Black Male With Psoriasis and Dyspigmentation

Successful Management of a Black Male With Psoriasis and Dyspigmentation Treated With Halobetasol Propionate 0.01%/Tazarotene 0.045% Lotion: Case Report

By | Case Reports, SOC Manuscripts | No Comments

Introduction

Skin of color patients with psoriasis face unique challenges related to disease characteristics and treatment. Distribution and severity of psoriasis may be greater in patients with skin of color.1,2 Dyspigmentation—including postinflammatory hypo- and hyperpigmentation—also more frequently and severely affects patients with skin of color3,4 and remains a challenge for dermatologists to manage.5 Finally, Black and Hispanic/Latino patients have demonstrated worse health-related quality of life (QoL) compared with White patients, as assessed by the Dermatology Life Quality Index (DLQI)6; these differences are likely related to several factors, which include varying cultural perceptions of skin disorders and the greater negative impact of dyspigmentation in patients with skin of color.2,7 The treatment of psoriasis commonly involves the use of topical corticosteroids, such as the superpotent topical corticosteroid halobetasol propionate (HP).8,9 Corticosteroids are anti-inflammatory, immunosuppressive, antiproliferative, and vasoconstrictive; however, tachyphylaxis and adverse events following long-term use remain a concern.8-10 The topical retinoid tazarotene (TAZ) has several mechanisms of action that modulate pathogenic factors of psoriasis—including normalizing markers of differentiation, proliferation, and inflammation—though TAZ used alone may induce cutaneous irritation.10-13 The combination of HP with TAZ may enhance efficacy in the treatment of psoriasis, reduce side effects of both active drugs, and sustain treatment response.10,11

A fixed combination lotion of HP 0.01% and TAZ 0.045% (HP/TAZ; Duobrii,® Ortho Dermatologics, Bridgewater, NJ) was developed utilizing a novel polymeric emulsion technology, which allows for rapid and uniform distribution of HP and TAZ, humectants, and moisturizers on the skin.10 Phase 3 clinical data have demonstrated efficacy and tolerability of HP/TAZ lotion in patients with moderate-to-severe localized plaque psoriasis.14,15 Here, we present a case report of a Black male with moderate plaque psoriasis who was successfully treated with once-daily HP/TAZ lotion over 8 weeks, with resolution of skin dyspigmentation by week 12.

Case Report

The patient was a 58-year-old, non-Hispanic, Black male with moderate psoriasis (Investigator’s Global Assessment [IGA]=3) and affected body surface area (BSA) of 10% at baseline (Table 1). The patient was enrolled in a phase 3, randomized, double-blind, vehicle-controlled study that assessed HP/TAZ lotion in participants with moderate-to-severe psoriasis (NCT02462070); detailed methodology and study results have been previously published.14,15 The patient, randomized to HP/TAZ for 8 weeks with a 4-week posttreatment follow-up, was instructed to apply a thin layer of HP/TAZ lotion once-daily over all affected areas. The target lesion (Figure 1), located on the upper right arm, was 99 cm2 in size at baseline; prominent keloid scars were also apparent. The patient also had an additional non-target lesion treated with HP/TAZ during the study (Figure 2). At baseline, both lesions appeared as classic psoriatic elevated plaques covered with white/silvery scales. By week 2 of HP/TAZ treatment, scales had diminished, though affected skin was hypopigmented in the center with hyperpigmentation at the border of the psoriatic plaque resolution. The degree of hypopigmentation appeared to be greatest at week 4, with skin pigmentation nearing normal by week 8. At 4 weeks posttreatment, the affected skin area had returned to normal with small regions of hyperpigmentation, the greatest around the periphery of the affected skin lesion.

The patient achieved treatment success with HP/TAZ lotion, with an improvement to ‘almost clear’ at week 4 that was maintained posttreatment at week 12 (Table 1). Improvements in affected BSA and signs of psoriasis at the target lesion were also observed early following treatment with HP/TAZ lotion and maintained up to 4 weeks posttreatment. The patient had substantial improvements in QoL during the study, with DLQI score decreasing from 9 (“moderate effect” on life) at baseline to 1 (“no effect” on life) at weeks 4 and 8.

No adverse events were reported. Dryness was the only local skin reaction present at baseline (assessed as moderate by the investigator), which subsided at weeks 2–6 and returned to mild dryness by study end (Table 1). No itching was reported during HP/TAZ treatment until posttreatment follow-up, where it was assessed as moderate. The patient did not report burning/stinging at any study visit. Further, there were no instances of skin atrophy, striae, telangiectasias, or folliculitis—other known drug-related skin reactions.

Discussion

Racial and ethnic differences in epidemiology, clinical features, genetic predisposition, and response to treatment of psoriasis are important to address given our increasingly diverse patient population.7 Here we report the management of psoriasis in a Black male enrolled in a clinical trial who was randomized to treatment with HP 0.01%/TAZ 0.045% lotion once daily for 8 weeks, with a 4-week posttreatment follow-up at week 12.

HP/TAZ was efficacious in this patient, who achieved an IGA score of 1 (almost clear) within 4 weeks and maintained treatment success at weeks 8 and 12. Affected BSA decreased 50% from baseline to week 8. Quality of life was improved in this patient, whose DLQI score by week 8 indicated “no effect” of psoriasis on the patient’s QoL, a substantial and clinically meaningful16 improvement from the “moderate effect” observed at baseline. A clinical feature of this patient was the presence of prominent keloid scars, which are benign fibrous growths resulting from an abnormal connective tissue response.17 While the cause of the keloids in this patient is not known, the presence of keloids is not unexpected, as there are racial differences in prevalence, with Black individuals forming keloids more often than White individuals.17

The patient experienced dyspigmentation of the affected skin during the trial, which is also not unexpected, given that resolution of psoriasis in darker skin is associated with both hypo- and hyper-pigmentation.18 Dyspigmentation is of particular concern, as it can have significant psychosocial impacts, contribute to greater negative emotions, and even be more bothersome than the psoriasis itself in patients with skin of color.2,4,7 Hypopigmentation was primarily experienced from weeks 2-8, with the greatest degree at week 4. By week 12 the affected skin area had returned to normal, with only small regions of hyperpigmentation, primarily around the periphery of the lesion. This relatively fast time to resolution is notable given that dyspigmented patches can take between 3 and 12 months to resolve.2

Skin color is primarily due to the presence of melanin, a pigment formed by immune cells called melanocytes. Melanin formation, or melanogenesis, is a complex process of melanin synthesis, transport, and release to keratinocytes, which occurs within organelles of melanocytes called melanosomes.19 The mechanisms and pathogenesis of postinflammatory hypo- and hyperpigmentation in psoriasis are not fully elucidated, though multiple hypotheses have been suggested. Inflammation-associated hypopigmentation may be a result of rapid turnover of keratinocytes during hyperplasia, which can interfere with melanosome transfer.18 Cutaneous inflammation, through signaling of growth factors and pro-inflammatory cytokines such as IL-17 and TNF-α, can also lead to hypopigmentation through inhibition of melanogenesis, 18,20 with more severe inflammation potentially leading to permanent pigmentary changes through loss or death of melanocytes.20 Interestingly, it has been observed that while hypopigmentation often accompanies active inflammation, patients are at risk of developing hyperpigmentation once the inflammation has resolved, potentially due to increased numbers and activity of melanocytes.18,21 This too may be the result of cytokine signaling during inflammation. For example, IL-17 and TNF-α can simultaneously suppress melanogenesis while also stimulating the proliferation of melanocytes; as such, upon resolution of inflammation, the increased number of melanocytes in lesional skin (without concurrent suppression of melanogenesis) will produce excess melanin, leading to postinflammatory hyperpigmentation.18

The fixed combination of HP and TAZ used to treat psoriasis in the patient from this case report resulted in psoriasis lesion clearance with self-limited postinflammatory hypopigmentation and low levels of hyperpigmentation observed by week 12. Topical corticosteroids, a mainstay of treatment for psoriasis,8 are used as first-line therapy for hyperpigmentation when combined with hydroquinone and topical retinoids.5,22 Corticosteroids are thought to be effective by decreasing cellular metabolism, thereby inhibiting melanin synthesis.22 Corticosteroids have also been shown to minimize the risk of postinflammatory hyperpigmentation after laser resurfacing.23 Topical retinoids are effective in treating postinflammatory hyperpigmentation with other agents as described above or as monotherapy.22 For example, TAZ 0.1% gel and cream have demonstrated efficacy in acne-related postinflammatory hyperpigmentation, significantly improving pigmentation intensity versus vehicle24,25; TAZ was also more effective than adapalene 0.3% gel in reducing hyperpigmentation.25 Tazarotene 0.1% cream is approved as an adjunctive treatment in the mitigation of facial mottled hyper- and hypopigmentation. Retinoids are thought to reduce hyperpigmentation through multiple mechanisms, including: stimulating keratinocyte turnover (promoting loss of melanin), reducing/inhibiting melanosome transfer to keratinocytes, and interrupting melanin synthesis.22,26 TAZ has also been shown to downregulate markers of cell proliferation and inflammation such as IL-6,12,13 which is known to have hypopigmenting effects.18

The fixed combination HP 0.01%/TAZ 0.045% lotion used by the patient in this case report has additional efficacy and safety benefits. The new polymeric emulsion technology used to develop HP/TAZ lotion allows for efficient permeation of the active ingredients into the dermal layers, at around half the concentration of traditional topical formulations.10 Further, HP/TAZ lotion has demonstrated synergistic activity, with efficacy greater than that which would be predicted from the individual active ingredients.10 The maintenance of therapeutic effect seen in this patient—who sustained disease reduction 4 weeks posttreatment—is likely due to the mechanism of action of TAZ in psoriasis, which restores skin to a quiescent, prelesional status.27 However, when used alone, TAZ can cause cutaneous irritation; HP alone can also result in AEs that limit long term use. These safety limitations can be minimized when combining HP with TAZ.10,11 The patient in this case report did not report any adverse events—including any application or irritation events—and local skin reactions were limited. Though the patient was limited to 8-weeks of HP/TAZ treatment as part of the clinical trial design, treatment with HP/TAZ for up to 1 year (maximum 24 weeks of continuous use) in an open-label, long-term study (NCT02462083) has demonstrated a favorable safety profile.28

Conclusion

In conclusion, this case report in a Black male patient demonstrates that this new formulation of HP 0.01%/TAZ 0.045% lotion was efficacious in the treatment of psoriasis, with treatment success achieved early and maintained 4 weeks posttreatment. Hypopigmentation was evident during resolution of disease, though had completely resolved by week 12 with minimal hyperpigmentation observed. These results indicate that HP/TAZ may be a treatment option for patients with skin of color, who are disproportionally affected by postinflammatory dyspigmentation.

Treating Alopecia in Skin of Color Patients: How to Arrest Loss and Promote Regrowth

By | Uncategorized | No Comments
Treating Alopecia in Skin of Color Patients

Source: Next Steps in Derm

Can you improve your culturally-competent hair loss consultation? Would you like to grow your toolbox for comprehensive alopecia treatment? If so, you are in the right place!

Hair loss is a frequent concern for patients visiting the dermatologist, especially in patients with pigmented skin types. Kinky or coiled hair has an innate fragility that makes African Americans especially prone to hair loss concerns. At the  2020 Skin of Color Virtual Update, Dr. Susan Taylor discussed Conventional Treatment Approaches for Hair & Scalp Disorders in Skin of Color Patients. Dr. Taylor advised how to have a culturally competent hair loss consultation, reviewed common patterns of hair loss, and highlighted comprehensive treatment of multifactorial causes of alopecia.

Before we get into therapeutic strategies for alopecia, let’s highlight important considerations to institute an effective treatment plan:

  • Understand common ethnic hairstyles and practices
  • Recognize the impact of hair and scalp disorders
  • Clearly identify the problem and obtain a thorough history, including details regarding hair care practices, products used, and symptoms
  • Complete physical examination and consider scalp biopsy
  • Accurately diagnose the disease (see Table 1 for common causes of alopecia)
  • Effectively and competently partner with the patient to treat the disorder with appropriate therapy
Common Cause of Scarring Non-Scarring Alopecia

Dr. Taylor stressed the importance of culturally competent questioning during the visit. For example, asking an African American woman if she shampoos daily can reduce the patient’s confidence in the physician’s understanding of her hair type, especially during a race discordant visit. To build confidence, it is critical to understand routine hair practices and to be familiar with common products.

During the hair loss consultation, it is important to understand the problem experienced by the patient. Frequent symptoms noted by the patient that can clue in the underlying alopecia include:

    • Hair length is not increasing.
    • There is hair breakage.
    • Hair is falling out at the root.
    • There is decreased hair density.
    • There is focal or localized hair loss.

Other considerations include the duration of hair loss, any associated symptoms, and presence of family history of hair loss. Further, it is important to ask about their hair care history. The types of hairstyles used by the patient and the hair care routine should be discussed.

The physical exam should be thorough to evaluate the scalp and hair density, a hair pull test, and examination of the eyebrows and eyelashes. The presence of weaves, braids, or wig caps may impede evaluation. If the patient has any of these hairpieces on the scalp that cannot be easily removed during the visit, the patient should return for evaluation after these are removed. History can still be discussed during the visit, however, the co-pay should be refunded, and the patient should be offered an earlier appointment for evaluation of the hair and scalp.

Now that we have discussed how to approach the consultation, let’s get into the alopecias! Dr. Taylor highlighted central centrifugal cicatricial alopecia, traction alopecia, and frontal fibrosing alopecia, as well as tips to minimize breakage, reduce hair tension, and scalp care to treat seborrheic dermatitis.

Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia seen in about 5.6% of African American women. It frequently starts with increased hair breakage at the vertex, and patients often have associated symptoms of itching, burning, tenderness, and soreness of the scalp. The goals of treatment are to aggressively treat the CCCA in the early stages to prevent progression, relieve symptoms, and possibly have some regrowth in the affected areas. There are no randomized controlled trials for CCCA treatment, thus evidence for treatment comes from case reports and series. The mainstay of treatment is corticosteroids (topical and intralesional), anti-inflammatory antibiotics, antimalarials, and minoxidil (topical and oral formulations). Anti-seborrheic shampoos, hair transplantation, and platelet-rich plasma injections serve as adjuncts to treatment. See Table 2 for detailed treatment options. Frequently multiple agents are used in combination to control the disease.

Two important areas of focus when treating CCCA that Dr. Taylor highlighted are practices to minimize hair breakage and treatment of frequently concurrent seborrheic dermatitis.

Cutaneous Sarcoidosis

Hypopigmented Cutaneous Sarcoidosis Responsive to Minocycline

By | Case Reports, SOC Manuscripts | No Comments

Hypopigmented patches and plaques are a rare presentation of cutaneous sarcoidosis. JDD authors describe a case of generalized hypopigmented cutaneous sarcoidosis that showed good response to minocycline therapy.

Introduction

A 58-year-old African-American male with a past medical history of hypertension, diabetes mellitus, tobacco use, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and hyperlipidemia presented with a two-year history of asymptomatic light spots on his trunk and upper extremities. He reported a history of cutaneous sarcoidosis a decade prior, characterized by erythematous papules and plaques that had regressed with hydroxychloroquine therapy. The newer light patches were not responsive to mid-potency topical steroids or tacrolimus 0.1% ointment. Review of systems was negative. The patient denied any new medications or history of travel outside of the metropolitan area.

 

Physical examination of the skin was significant for multiple hypopigmented patches on the face, neck, and extremities; hypopigmented plaques on the back (Figure 1); and annular plaques of hypopigmented papules on the chest and abdomen (Figure 2). The lesions were not hypoesthetic. There was no lymphadenopathy and physical exam was otherwise unremarkable.

 

A biopsy from the left arm showed a superficial and deep multinodular granulomatous infiltrate sparing the epidermis (Figure 3). The granulomas were predominantly composed of epithelioid histiocytes with a few scattered lymphocytes (Figure 4). Special stains for microorganisms were negative. There was no appreciable epidermal change or pigment incontinence. The histopathological picture was consistent with recurrent cutaneous sarcoidosis.
Computed tomography of the chest with and without contrast showed no evidence of active pulmonary sarcoidosis or lymphadenopathy. An ophthalmologic exam, abdominal ultrasound, and spirometry were within normal limits, as were serum cal cium and angiotensin-converting enzyme (ACE) levels.

 

Because the patient’s skin manifestations had resolved with hydroxychloroquine in the past, this treatment was restarted at 200 mg twice-daily. Unfortunately, laboratory monitoring revealed hepatic transaminitis and mild anemia 2 months into the treatment course, corresponding with only minimal improvement of the hypopigmented plaques, necessitating discontinuation of hydroxychloroquine. Minocycline at a dose of 100 mg twice daily was then initiated 4 months after normalization of liver function tests. After 5 months of treatment, all hypopigmented patches, papules, and plaques had completely or partially repigmented and were appreciably smoother and flatter (Figures 5 and 6). The patient tolerated the medication well with no adverse effects.

Discussion

The skin is one of myriad organs potentially affected by sarcoidosis, a multisystem idiopathic disorder characterized histologically by infiltration of noncaseating granulomas. Cutaneous manifestations of sarcoidosis are protean, including papules and plaques of various morphology and distribution, subcutaneous nodules, pruritus, ichthyosis, erythroderma, ulceration, verrucosis, nail disease, and infiltrative scars.1 In the United States, sarcoidosis is more common in African-Americans than in other ethnic groups, and cutaneous manifestations in individuals of African descent are more likely to be atypical.2

In 1973, Cornelius et al reported 4 patients who presented with hypopigmented and depigmented patches and plaques that showed the naked tuberculoid granulomas characteristic of sarcoidosis on skin biopsy.3 The distribution in these cases was variable, with generalization in one patient and localization to the face, legs only, or legs and arms in the other three. Histologically, no difference in epidermal melanocyte count was noted between affected and unaffected skin, but relative hypomelanosis of the malphigian and corneal layers was appreciated. All patients had multisystem disease. Four years later, Hubler described a “hypomelanotic canopy” in a woman with lupus pernio and lymphadenopathy whose hypopigmented patches overlay deep subcutaneous nodules on the arms.4Biopsy of an enlarged lymph node revealed epithelioid granulomas that were reduplicated on skin biopsy. Interestingly, cutaneous hypopigmentation lacking any histological evidence of granulomatous dermatitis has also been observed in the setting of systemic sarcoidosis;5,6 this highlights the need for vigilant continued surveillance when the clinical index of suspicion for sarcoidosis is high and biopsy is noncorroborative.

 

The etiopathogenesis of hypopigmentation in sarcoidosis, like the disease itself, is unknown. Theories regarding the likely mul tifactorial cause of sarcoidosis center around T-cell—mediated autoimmunity, genetic predisposition, and aberrant response to bacterial or other antigens; the evidence for each has been extensively reviewed elsewhere.1,7 The rare cutaneous hypopigmentation seen in dark-skinned individuals with sarcoidosis appears to represent a melanopenic hypomelanosis, as opposed to postinflammatory hypopigmentation or melanocytopenia.3,4,8 In our patient, there were no epidermal changes, interface in flammation, or melanin-containing dermal macrophages to suggest postinflammatory dyspigmentation.

 

Minocycline represents an attractive alternative treatment for chronic sarcoidosis in patients who might otherwise be treated with long-term corticosteroids, antimalarials, methotrexate, or other immunosuppressants. The tetracycline class of antibiotics has previously demonstrated utility in a variety of dermatoses and autoimmune-connective tissue diseases, and may be particularly efficacious for granulomatous skin conditions.9,10 Tetracyclines have specifically shown efficacy in the treatment of granulomatous periorificial dermatitis, cheilitis granulomatosa, granulomatous rosacea, and silicone granulomas.11-14 More recently, tetracyclines proved beneficial in treating granuloma annulare (GA), an entity often with significant clinicopathological overlap with cutaneous sarcoidosis.15,16 Marcus et al showed that, in combination with rifampin and ofloxacin, 3 to 5 courses of monthly minocycline therapy led to complete clearance of GA in 6 patients, half of whom had generalized disease.15 In this series, the rationale for selection of the same triple combination antimicrobial therapy as that used for paucibacillary leprosy (PBL) was that the clinical and histological similarities between PBL and GA might impart an equally similar response to treatment. The same logic could be extrapolated further to include patients with cutaneous sarcoidosis as candidates for a treatment regimen, including minocycline, with or without rifampin and ofloxacin.

 

Minocycline as monotherapy was efficacious for the treatment of chronic cutaneous sarcoidosis in an open observational study of 12 patients by Bachelez et al.17 The cutaneous manifestations of patients in the Bachelez group included classic plaques, papulonodules, subcutaneous nodules, and lupus pernio. Ten of 12 patients completely or partially responded to treatment, which was generally well tolerated except for drug hypersensitivity syndrome in one patient with a history of other autoimmune diseases. Park et al later reported a patient with cutaneous, lacrimal gland, pulmonary, and ocular (choroidal) sarcoidosis that responded to minocycline.18

Miyazaki et al described a patient with a unique presentation of muscular sarcoidosis of the limbs, as well as uveitis and pulmonary disease, in whom clinical response to minocycline was paralleled by normalization of an elevated ACE level.19 The patient relapsed off of minocycline, but rapidly responded to reintroduction of the medication. Immunohistochemical staining of muscle biopsy specimens for Propionibacterium acnes showed multiple small particles within granuloma macrophages and giant cells, substantiating the theory that sarcoidosis is an infectious disease or an aberrant immunologic response to bacteria. Evidence for the role of other infectious agents in sarcoidosis, especially Mycobacterium tuberculosis, has been mixed and inconclusive.20 That sarcoidosis is purely an infectious disease is certainly within the realm of possibility,21 but the recurrence of disease once antibiotics are discontinued argues against this theory.19 An alternative explanation is that the benefits of tetracyclines in sarcoidosis and other autoimmune diseases are derived more from their nonantibiotic immunomodulating properties. The anti-inflammatory properties ascribed to minocycline include inhibition of T cell activation, proliferation, and transmigration as well as expression of nitric oxide synthetase and matrix metallopeptidase 9 (MMP-9).9Furthermore, tetracyclines have been shown to inhibit granuloma formation in vitro.22

 

Conclusion

The role of tetracyclines in the therapeutic armamentarium of sarcoidosis, especially in those who cannot tolerate antimalarials or other immunomodulating medications, is likely to expand. Whether minocycline is particularly effective for the hypopigmented variety of cutaneous sarcoidosis remains to be seen.

Pemphigus Foliaceus

Psoriasiform Pemphigus Foliaceus in an African American Female: An Important Clinical Manifestation

By | Case Reports, SOC Manuscripts | No Comments

JDD authors document and highlight this atypical psoriasiform presentation of Pemphigus Foliaceus in a patient with skin of color to raise awareness and improve diagnosis and outcomes.

Case Report

A 50-year-old African-American woman presented to the dermatology clinic with a pruritic eruption of 3 years’ duration that began as discrete plaques on the inframammary folds and subsequently spread towards the mid-chest, ears, back, elbows, knees, and scalp. Past treatments by other clinicians included clotrimazole cream and a topical corticosteroid of unknown potency without significant improvement. She denied any new medications and was taking aspirin, divalproex, mirtazapine, cetirizine, venlafaxine, atorvastatin, and omeprazole.

On clinical examination, the patient had well-demarcated, pink, atrophic plaques and superficial erosions over the inframammary folds and mid-chest (Figures 1). She also had well-demarcated, hyperpigmented, hyperkeratotic scaly plaques over the abdomen, suprapubic region, elbows, knees, and back with sporadic small superficial blisters (Figure 2). Complete blood count, complete metabolic panel, rheumatoid factor, and antinuclear antibody were within normal limits. Rapid plasma reagin test was negative. Erythrocyte sedimentation rate was elevated at 54 millimeter/hour (reference range 0-22 millimeter/hour). A punch biopsy of the right abdomen was performed and revealed psoriasiform epidermal hyperplasia, focal parakeratosis, and acantholysis throughout the superficial spinous and granular layers (Figure 3). Only a sparse inflammatory infiltrate was present in the underlying dermis. These clinical and histological findings supported the diagnosis of pemphigus foliaceus (PF). Patient was started on 50 mg oral dapsone daily.

Discussion

Herein, we present a case of Pemphigus Foliaceus with a psoriasiform clinical presentation in an African-American patient. PF is an autoimmune skin disease caused by antibodies against the desmosomal glycoprotein, desmoglein 1.¹ Desmogleins, members of the cadherin family, serve to anchor epidermal desmosomes between adjacent keratinocytes and assist in epithelial differentiation.² Antibodies targeting desmoglein 1 result in acantholysis in the upper epidermis with limited separation in the basal layers and minimal mucosal involvement as desmoglein 1 is primarily expressed in the granular layer of the non-mucosal epidermis.¹ Patients present with scaly plaques on an erythematous base and fragile shallow blisters which are infrequently found intact; rarely, the condition can progress to exfoliative erythroderma.1,3 Initially, PF usually presents on the trunk, face, or scalp, but may subsequently involve other regions of the skin.1 Diagnosis may be confirmed with biopsy and direct immunofluorescence with intercellular IgG and C3 limited to the upper epidermis. Treatment includes oral and topical steroids, azathioprine, dapsone, and rituximab. The differential diagnosis for PF may include systemic lupus erythematosus, bullous impetigo, psoriasis, and seborrheic keratosis depending on the presentation.1

Physical exam findings in this patient were suggestive of PF due to the presence of superficial secondary erosions and “corn flake-like” scales, but psoriasis was included in the differential diagnosis due to the presence of discrete plaques with an erythematous border. PF is a relatively rare condition with a prevalence of less than 1 case per 100,000 and is about 5 to 10 times less common than pemphigus vulgaris.4 In contrast, psoriasis impacts approximately 2-4% of people in the United States.5 An endemic form of PF, fogo selvagem, has been reported in Brazil, Colombia, Peru, and Tunisia, while pemphigus vulgaris is more common in Mediterranean and Ashkenazi Jewish populations.4

We hypothesize that patients with psoriasiform presentations of PF may be misdiagnosed with plaque psoriasis. One author (JJ) has previous significant clinical experience with patients with skin of color and has seen other skin of color patients present with a psoriasiform manifestation of PF. PF and psoriasis share similar treatments including topical corticosteroids and immunosuppressants, and this may lead to underreporting of PF with psoriasiform manifestations. It is important to distinguish between these findings as there is evidence that ultraviolet light, a common treatment for psoriasis, may exacerbate PF.6,7 We performed a search of the published literature and identified one article that describes three patients with pemphigus erythematosus, a variant of PF, which was misdiagnosed as psoriasis.8 No identified articles described cases of PF with a psoriasiform presentation in patients with skin of color. We document and highlight this atypical psoriasiform presentation of PF in a patient with skin of color to raise awareness and improve diagnosis and patient outcomes.

SOCU Pearls Galore: AD, HS, Hair Care in SOC, and Medication Compliance Among Teens

By | Uncategorized | No Comments
Skin of Color Update Q&A Session Pearls

Source: Next Steps in Derm

The following is a summary of one of the many Q&A sessions held during the 2020 Skin of Color Virtual Update. During this particular session, questions were moderated by SOCU Co-Chair Dr. Andrew Alexis and answered by Drs. Ginette Okoye and Candrice Heath. The audience posed important questions and the faculty offered insightful answers regarding atopic dermatitis, hidradenitis suppurativa, hairstyle recommendations for patients with traction alopecia and follicular disorders,  and medication compliance among teens.

Q1. Dr. Alexis: “Dr. Okoye, when do you use spironolactone for Hidradenitis Suppurativa and when do you consider it for patients? What has been your experience?”

A1. Dr. Okoye: “Thank you for your question. Spironolactone like metformin is a good adjunct for other treatments with HS. I really never use it alone. It’s not a slam dunk by any means. I combine it with other modalities like metformin or a biologic or even antibiotics. I prefer to use spironolactone in patients who report flair with their menses. I specifically target these patients. I usually start at 50 mg/day or 100 mg/day, depending on their weight, intending to go as high as 200 mg/day.  If they can tolerate it, I will leave them on that. It is one of the many layers as I mentioned.”

Q2. Dr. Alexis: “Excellent. Staying on the same theme of HS, a real burning question a lot of us have is what if you’ve tried adalimumab for HS and it’s not working? What do you do next?”

A2. Dr. Okoye: “There are 3 types of people who receive adalimumab. There are patients with a nice response who get about 50 percent or maybe a little bit more. There are patients that are the same and nothing happens, according to the patient, and then there are people who seem to get worse. For the latter two groups, I try to stick with a biologic and attack a different pole of the immune system. My next option is usually Utsekinumab. First, because it is not a TNF alpha inhibitor and second, it has weight-based dosing, I can use a higher dose and use it every 4 weeks if I can get it covered. I’ve also had better luck getting it covered by insurance than the other biologics. I would say maybe a year or two ago, my next option may have been infliximab but if I find a patient does not respond to adalimumab that TNF alpha pole of the disease may not be as active in that person so I tend not to use infliximab in those patients anymore.”

Q3. Dr. Alexis: “Thank you. That’s very helpful. I’m going to give you one last HS question for the time being before we shift gears. This is a practical one in terms of diagnostic criteria for HS. The audience member says he or she has a lot of patients who have recurrent folliculitis of the thighs with one or more comedones in the area and would this be considered an HS variant?”

A3. Dr. Okoye: “Well, it depends. In order to diagnose someone with HS, we need to have typical HS lesions in typical HS locations (intertriginous areas) and they need to have recurrences. Some of these lesions include abscesses and sinus tracts.  Follicular papules and follicular pustules can be one of those typical lesions of HS, in my opinion. There are different subtypes of HS. One of them is called follicular subtype with more of a folliculitis type picture and they can have epidermal inclusion cysts and comedones. So yes, I suspect that your patient does have HS, just this particular subtype.”

Q4. Dr. Alexis: “Terrific, thank you. Now over to Dr. Heath. A general but very practical question. What pearls do you have for addressing medication compliance among teens since we know that is a unique group with unique challenges?”

A4. Dr. Heath: “Absolutely. I love the teenage population. One of my biggest tips is definitely to let them off the hook. So, what I mean by that is let them know they don’t have to do the regimen every single day. Say this in front of the parents so that skin disease does not become a battle at home. If the parents are not bugging them about it all the time, and the kid actually does commit to using it a few times and see some improvement, then I definitely let them know “great, you made and effort, let’s try to step it up if you can”. This strategy helps decrease the battle between parents and teens. Also, get them engaged in the visit. It is their skin so I speak directly to the teenager, especially if the parent is answering a lot about the patient’s health history questions, in which case I politely stop them and tell them that I really want to hear from the patient (and say the patient’s name). This makes them feel that it is their body and a really important time in their life where they can start to feel independence and positivity around seeking health care in general. One other tip is, once I give them step by step instructions to follow, I ask them to snap a picture with their cell phone or give them the idea of hanging the directions on the mirror in the bathroom, which can serve as a reminder. Those are just a few tips!”

Q5.  Dr. Alexis: “Another question for you Dr. Heath, about hair. What hairstyles do you typically recommend to patients and their families in the context of traction alopecia and follicular disorders that you see commonly in SOC and do you partner with any salons in the area?”

A5. Dr. Heath: “This is a very important question.  Not everyone is well versed in what is the cool hairstyle of the day. I simply start with whatever hairstyle you choose if it hurts, I would like for you to stop or loosen it. Also, if braids or cornrows are being used, I ask them “what about making the hairstyle already look like it’s one or two weeks old?”. This gives them a visual of how loose the braids should be to the scalp. I have not given a specific hairstyle, but I have given them some guidance. If it hurts, then you should stop or modify, and if it requires braids close to the scalp make it look older. Another example is doing crochet braids. This hairstyle involves hair being braided back and then just like you are knitting, very lightweight hair is attached to the braids going back. Often this is done with synthetic hair and the style doesn’t last as long as with regular human hair. So this does two things: 1) I have instructed them to use a hair that is now lighter, and a hairstyle that will self-destruct way sooner than something they would have spent 300 dollars on, so they would feel more comfortable replacing it because they didn’t spend that much. With regards to partnering with salons, if you’re new to a specific area or you’re just venturing out with skin of color and you want to give them more resources, one great place to start is online. I’m active on social media and a lot of salons and hairstylists will put their work online. I examine their work and look at the content they produce to see if we have the same hair values. See if they’re talking about healthy hair or if they have hairstyles that look too tight. Sometimes it can take time. Don’t rush it. Ask your patients who have very well-maintained hair that does not look tight: “Oh who does your hair? They’re doing a great job on their side while we are treating you medically.” You can make a list and go online and look these people up. You can talk to them or stop by. It helps them to know that you are invested in this person getting better and you’d love for them to have the client for a long time. But if the client doesn’t have any hair, they won’t be able to go there for a long time., so we (both parties) have a common goal”.

A5. Dr. Alexis: “Similar approaches have worked for me. Sometimes I will get patients who have very early CCCA/traction alopecia sent by the stylist and I want to know who that stylist is! I have a handful of excellent ones who can diagnose it early I have a very good relationship with them!”

Q6. Dr. Alexis: “I have some questions for myself that I’m going to take about atopic dermatitis.  One question that I have is about hyperpigmentation and lichenification left behind from an atopic dermatitis flare. How do you manage the pigmentary sequelae?”

A6. Dr. Alexis: “This is really an area where we want to educate the patient on the importance of treating the underlying cause of the pigmentary sequelae. There is no use in chasing after hyperpigmentation without actually controlling the chronic, underlying inflammatory disease that is atopic dermatitis. So really emphasize the core aspects of treating the active disease. As far as treating the pigmentation itself, you are left with an area of persistent post-inflammatory hyperpigmentation. My treatment of that is delayed action. Why? Because many of the skin lightening agents that we would consider can be irritating to the skin especially in the context of someone who has a compromised barrier as an atopic dermatitis patient would. The endpoint for knowing when is the time to consider a bleaching agent is when I or the patient palpate the area and it’s completely smooth and there is no elevation, scaling,  any sign of erythema whatsoever, no pruritus and it is just a persistent hyperpigmented macule or a patch, that persisted there for at least four weeks after the last activity. That’s when you want to consider a bleaching agent, not before. Really leveraging the non-corticosteroid topical agents such as TCIs, PDE4 inhibitors, and also if it’s a more moderate to severe patient, systemic agents like Dupilumab really can improve the sequalae too, anecdotally, because if you control the underlying inflammatory pathways there is less development of new areas of dyspigmentation and you have a better opportunity to clear the pigmentation that does occur.”

Alopecia in Skin of Color: Alternative Therapies

By | Uncategorized | No Comments
Alopecia in Skin of Color Dermatology Conference

Source: Next Steps in Derm

Management of alopecia in skin of color is challenging due to a paucity of research into its pathophysiology coupled with a poor understanding of the basic hair care practices in this patient population. For the patient, it is often associated with severe emotional distress. Unfortunately, many forms of hair loss are refractory to standard therapies.

At the 2020 Skin of Color Virtual Update, Dr. Crystal Aguh highlighted emerging therapies for various forms of alopecia in skin of color as our understanding of these conditions continue to unfold.

Central Centrifugal Cicatricial Alopecia (CCCA) is the prototypical form of hair loss in black women. It is a progressive form of scarring alopecia where fibrosis, not inflammation, is the predominant finding. The literature supports preferential expression of fibroproliferative genes in patients with CCCA. In fact, Dr. Aguh’s group demonstrated that PRKAA2, a gene that encodes for adenosine monophosphate kinase (AMPK), was under-expressed by a 1/3 in CCCA scalp samples.

So why metformin?

Reduced activity of AMPK is also implicated in the pathogenesis of hepatic fibrosis and idiopathic pulmonary fibrosis. In mouse model of IPF, metformin was found to reverse and accelerate resolution of the fibrotic processes via deactivation and apoptosis of myofibroblasts through AMPK activation.

    • Dosage: 10-20% Topical Metformin compounded in lipoderm once daily.
    • At that concentration, there is limited systemic absorption.
    • Main side effects are scalp dryness and irritation. Dr. Aguh recommends applying light oil (olive or Jojoba) coat to scalp to help with irritation and dryness.
    • It works 10-15 % of the time.

Another form of alopecia that disproportionately affects women is Lichen planopilaris (LPP). LPP is an inflammatory form of primary scarring alopecia. Signs of clinical activity include follicular hyperkeratosis, perifollicular erythema, and loss of follicular ostia. Patients also report loss of body hair. Meanwhile frontal fibrosing alopecia (FFA) is a subtype of lichen planopilaris characterized by slow recession of the frontal and bitemporal hairline. Dr. Aguh highlighted two adjunctive options for the treatment of LPP and FFA for patients who have failed standard therapies.

1. Naltrexone

    • mu-opioid receptor antagonist currently FDA approved for the treatment of opioid and alcohol dependence. In dermatology, it has been used off-label for the treatment of pruritus and as an anti-inflammatory agent.
    • It is hypothesized that lower than standard doses of naltrexone inhibits cellular proliferation of T and B cells and block Toll-like receptor 4, resulting in an analgesic and anti-inflammatory effect.
    • In one case series of four patients with LPP, use of naltrexone led to reduction in symptoms of pruritus, clinical evidence of inflammation of the scalp, and disease progression.
    • Dose: 3 mg daily
    • Drawback: 3 mg pills have to be compounded as the standard pill comes in 50 mg

2. 3% Tacrolimus cleanser (in Cetaphil cleanser)

    • Tacrolimus is a commonly anti-inflammatory agent for inflammatory skin conditions including lichen planopilaris.
    • Higher strengths of tacrolimus can be compounded to improve efficacy.
    • One retrospective study demonstrated that patients treated with 0.3% tacrolimus were significantly more likely to stabilize in 3 months compared with patients treated with clobetasol/betamethasone.
    • Drawback: very expensive. It costs about $120 for 30 ml of cleanser.

Acquired Trichorrhexis Nodosa (ATN) is a recurrent hair breakage that occurs as a result of damaging hair practices. Common culprits include chemical relaxers, thermal styling, and hair coloring. Patients will often complain of lack of hair growth. It can involve all parts of the scalp but nape of the neck is often affected. Dr. Aguh’s stressed that proper hair care is key for successful treatment. She proposed the following regimen for curly damaged hair:

    • Apply protein treatment to dry or damp hair. Cover with shower cap or heating source for 30 minutes.
    • Wash hair once weekly with gentle shampoo (sulfate-free or containing a gentle sulfate)
    • Deep condition with every shampoo. Follow deep conditioning with moisturizing rinse-out conditioner.
    • Add leave in conditioner after washing, at least 3x/week. Glycerin based leave in conditioners can be especially helpful for very dry hair
    • End washing session with light oil.

Traction Alopecia is another very common form of hair loss, especially in black women. It is likely due to the curly hair type, intrinsic low density of the hair at baseline as well as hairstyle practices. Dr. Aguh found that oral minoxidil, in lieu of topical minoxidil, is very effective for this type of hair loss.
