Comparison of overall efficacy and safety of oral versus subcutaneous methotrexate in severe psoriasis.

Subcutaneous (SC) methotrexate (MTX) is considered to be associated with a higher and predictable linear bioavailability as compared to oral MTX. Although various studies have reported SC MTX to be safe and effective in psoriasis, prospective head-to-head comparative trials on oral versus SC MTX are limited. To compare the efficacy and safety of SC versus oral MTX in severe psoriasis. It was a prospective, single-blinded, randomized controlled trial, in 100 eligible, adult patients of severe psoriasis randomized into two groups. Group-A (n = 50) patients were started on oral MTX at a full dose of 0.3 mg/kg/week (maximum 25 mg/week) given for 12 weeks or till achieving PASI90 [90% reduction in Psoriasis Area Severity Index (PASI) from baseline], whichever was earlier and group-B (n = 50) patients received SC MTX in the same dose and duration. MTX was then tapered gradually at 5 mg every 2 weeks and stopped. All patients were followed-up for 24 weeks post-treatment with monthly assessment of PASI and Dermatology Life Quality Index (DLQI) scores. Baseline demographic profiles of patients in both the groups were comparable. The mean ± SD baseline PASI scores were group-A: 15.1 ± 3.2 versus group-B:15.7 ± 3.3 (p = 0.35). The number of patients that achieved PASI90 at or before 12 weeks of treatment was numerically higher in group-B (39/50, 78%) versus group-A (31/50, 62%; p = 0.08) and the time to achieve PASI90 was significantly lesser (p < 0.001).Also, the percentage(%) decline in DLQI was significantly higher in group-B(p = 0.003). The overall side-effect profile was comparable between groups (p = 0.31), but the frequency of gastrointestinal side-effects was significantly less in group-B (p = 0.04). Among those patients who achieved a PASI90 response by week12, relapse rates were comparable during the subsequent 24-week follow-up period [group-A: 12/31 (39%), group-B: 11/39 (28%), and p-value = 0.33]. SC MTX results in a significantly faster achievement of PASI90 and greater reduction in DLQI as compared to oral MTX in patients who are candidates for systemic therapy with a comparable safety profile.

Psychological morbidity in pemphigus patients in clinical remission and its relation with clinico-demographic parameters.

BACKGROUND AND OBJECTIVES: Significant psychological morbidity exists in patients with active pemphigus. Pemphigus being a chronic disease, psychological morbidity may exist in pemphigus patients in remission as well. The objectives of the study were to assess the psychological morbidity in pemphigus patients in clinical remission and to correlate it with clinico-demographic parameters. PATIENTS AND METHODS: Pemphigus patients in clinical remission were consecutively included and were asked to respond to the Hindi/English version of Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD-7) and panic disorder module of PHQ. RESULTS: Of 107 patients recruited, 41 (38.3 %, 95 % CI: 29.1-48.2 %) patients were found to have either depression (33 [30.8 %, 95 % CI: 22.2-40.5 %]) or anxiety (38 [35.5 %, 95 % CI: 26.5-45.4 %] syndrome based on cut-offs of PHQ-9 score and GAD-7 score, respectively. Number of patients with mild, moderate and moderately severe/severe depression syndrome were 26 (24.3 %, 95 % CI: 17.2-33.2 %), 7 (6.5 %, 95 % CI: 0.3-12.9 %) and 0 respectively and patients with mild, moderate, severe anxiety syndrome were 29 (27.1 %, 95 % CI: 19.6-36.2 %), 9 (8.4 %, 95 % CI: 4.5-15.2 %) and 0 respectively. Patients with anxiety or depression syndrome had significantly higher clinical disease activity in the past, number of days spent in dermatology inpatient and significantly shorter clinical remission at the time of assessment as compared to those without these symptoms. CONCLUSIONS: Significant burden of mild/moderate depression or anxiety syndrome associated with past severity of disease and shorter duration of clinical remission was found.

Oral cyclosporine is effective in stabilizing active vitiligo: Results of a randomized controlled trial.

Oral dexamethasone mini pulse (OMP) is an established treatment modality for active vitiligo. Cyclosporine may have therapeutic role in active vitiligo but current evidence supporting its role is scarce. The objective of study was to compare the efficacy and safety of oral cyclosporine with OMP in patients of active vitiligo. Fifty patients with active vitiligo were randomized into two groups of 25 patients. Group 1 was treated with OMP (2.5 mg dexamethasone) on two consecutive days/week for 4 months while group 2 was treated with cyclosporine (3 mg/kg/day) for 4 months. Laboratory monitoring was performed as per the prevalent protocol. The patients were followed up for another 2 months after stopping treatment. Arrest of disease progression (ADP) was defined as change of vitiligo disease activity score from 4+ to 3+ (time elapsed since last disease activity being more than 6 weeks upto 3 months) during the study period (6 months). ADP was attained in 21 patients in group 1 and 22 patients in group 2 (84% vs. 88%, p = 1.00) at the end of 6 months. However, mean time to achieve ADP was significantly lower in group 2 as compared to group 1 (10.92 [4.12] weeks vs. 13.90 [3.92] weeks, p = 0.01). Extent of repigmentation, improvement in patient assessment score, vitiligo quality of life and clinical markers of disease activity were marginal and comparable in both groups. Cyclosporine leads to earlier disease stabilization in active vitiligo as compared to OMP. Although considered a rescue drug in dermatology, low dose cyclosporine can be an effective therapeutic alternative in vitiligo patients.

Oral mycophenolate mofetil in the treatment of acquired dermal macular hyperpigmentation: An open-label pilot study.

BACKGROUND: Literature on treating acquired dermal macular hyperpigmentation is sparse. AIMS AND OBJECTIVES: To assess treatment response of mycophenolate mofetil in patients having acquired dermal macular hyperpigmentation. MATERIAL AND METHODS: In this open-label, pilot study, patients of acquired dermal macular hyperpigmentation affecting at least the face and/or neck were included. Each participant was treated with mycophenolate mofetil 2 g/day for 24 weeks, with a follow-up of 12 weeks. Two aspects of disease severity were measured: activity (appearance of new lesions/extension of existing lesions), and degree of hyperpigmentation (measured using 'dermal pigmentation area and severity index'). Patient satisfaction was assessed on a scale of 0-10. RESULTS: Forty-three of 46 patients who were prescribed mycophenolate, completed the study (40 females, 6 males; mean disease duration 2.8 ± 1.4 years). Amongst 20 (43.5%) patients with active disease, stability was achieved in 17, after a mean duration of 6.1 ± 2.5 weeks (range 4-12 weeks; median 4; IQR 4 weeks). Mean dermal pigmentation area and severity index at baseline was 18.8 ± 7.1 and decreased to 13.7 ± 6.3 at 24th week (27.5 ± 14.7%; P < 0.001). A significant decreasing trend in dermal pigmentation area and severity index (P < 0.001) was observed, and first significant difference from baseline was noted at the 16th week (P 0.008). Less than 10%, >10-20%, >20%-30%, >30%-40%, >40%-50%, and >50% reduction in dermal pigmentation area and severity index was observed in 8, 5, 4, 15, 10 and 1 patients/patient respectively. The maximum mean grade of pre-treatment dermatoscopic severity was 3 ± 0.7, and decreased to 2.1 ± 0.8 on the face (P < 0.001) and 2.4 ± 0.7 on the neck (P < 0.001) post-treatment. There were 9 (20.1%) non-responders. Self-assessment scores of the rest of the patients fell in the range of moderate/fair improvement (>5 to 7). No significant correlation was seen between patient satisfaction score and degree of reduction in dermal pigmentation area and severity index (r -0.39). Three developed adverse effects (leucopenia, n = 1; transaminitis and hyperbilirubinemia, n = 2) that resolved following discontinuation of mycophenolate. CONCLUSION: Mycophenolate mofetil appears to be a promising treatment option in acquired dermal macular hyperpigmentation.

Changing paradigms of dermatology practice in developing nations in the shadow of COVID-19: Lessons learnt from the pandemic.

At present, routine dermatology practices stay mostly disrupted worldwide owing to the ongoing COVID-19 pandemic. However, dermatology services need to be resumed in future and dermatologists especially in developing countries face a mammoth task of devising plans to tackle the upcoming surge of patients while still maintaining the precautions to avoid risk of infection to health care workers and our patients. Teledermatology practice is a viable alternative and there is need of starting functioning teledermatology centers at primary health care centers and training health care workers in telemedicine. Several steps like increasing the working hours of outpatient clinics, posting dermatologists and health staffs in shifts, encouraging online registration and payment, providing time slots to patients should be taken to prevent overcrowding at outpatient departments in hospitals of developing countries like India where the usual patient turnover during summers maybe around 600 to 800 per day. Once diagnosed by the dermatologist, a subsequent meticulous use of teledermatology can limit the number of follow-up visits. To avoid student gatherings, the undergraduate and postgraduate teaching schedule should be replaced by online or virtual teaching in form of webinars and video conferencing. Above all, intense upgradation of health care infrastructure, recruitment, training of new health care staffs on mass level and huge investment in health care sector is required in all the developing countries.

Intralesional sclerotherapy for the treatment of acne cysts: A case series.

Acne cysts are a common dermatological problem that often leads to scarring and a significant negative impact on patients' psyche. The aim of the study was to evaluate the usefulness of intralesional foam sclerotherapy for the treatment of cystic acne. Patients with cystic acne treated with intralesional foam sclerotherapy between June 2018 and May 2019 were identified. Treatment response and adverse effects were assessed during follow-up. Twelve patients (10 men and 2 women) with cystic acne with a median age of 21 years were treated during the study period. Of these 12 patients, eight (66.7%) showed complete resolution within 48 hours and two (16.7%) experienced complete resolution within 1 week. Two patients failed treatment at the end of the 4-week follow-up. Of the two patients with more than one acne cyst, response was noted only at the treated site. All patients who showed improvement sustained the effects at the 12-week follow-up. No adverse effects were observed and the treated sites healed with good cosmesis and minimal scarring. To conclude, single-session percutaneous polidocanol sclerotherapy is useful for the treatment of acne cysts. Future controlled studies are required to compare the efficacy of intralesional sclerotherapy with intralesional corticosteroids.

A critical appraisal on pure neuritic leprosy from India after achieving WHO global target of leprosy elimination.

Background: Clinical data on pure-neuritic leprosy (PNL) is limited. Objective: To study the clinical and epidemiological features of PNL in the leprosy post-elimination era. Methods: This was a retrospective analysis of the clinic records of leprosy patients from January 2006 to June 2013. Data regarding age, sex, disease duration, presenting complaints, nerves affected, complications and treatment received were extracted from PNL cases. Results: Among 906 registered leprosy cases, 48 (5·3%) were found to have PNL. The mean age was 36·9 ± 16·2 years and predominantly males were affected (85·4%). The mean delay between onset of symptoms and diagnosis was 2·1 ± 2·2 years. Multiple nerves were affected in 36 patients (75%) and 12 (25%) had only one nerve involved. Visible deformities at presentation were noted in 32 (66·7%) patients. Forty patients (83·3%) were treated with multi drug therapy-multibacillary (MDTMB) regimen and three (6·25%) were treated with MDT-paucibacillary regimen. Twenty-one patients (43·8%) were considered positive responders to treatment. There was no correlation between the duration of NFI and treatment outcome. Conclusion: PNL continues to occur in the post-elimination era. Grade 2 deformities are common in PNL compared to other leprosy patients because of delayed diagnosis and treatment. Distinct diagnosis and treatment guidelines and sensitisation of health care workers and physicians to the occurrence of PNL is the need of the day.
