Non-blinded trials of pemphigus vulgaris suggest that mycophenolate mofetil (MMF) may be beneficial. In a prospective, multicenter trial, outpatients with mild or moderate pemphigus vulgaris were randomized to MMF (2 or 3gday−1) plus oral corticosteroids or placebo plus oral corticosteroids for 52 weeks. The primary end point was the proportion of patients in the placebo and combined MMF groups responding to treatment (absence of new, persistent oral or cutaneous lesions, and prednisone dose ≤10mgday−1 from weeks 48 to 52). Of 96 randomized patients, 94 were given treatment and 75 completed the study. Treatment responses occurred in 40 of 58 patients (69.0%) in the combined MMF group and 23 of 36 (63.9%) in the placebo group (P=0.6558, 95% confidence interval –17.4 to 27.6). MMF-treated patients showed faster and more durable responses. In post hoc analyses, more patients taking MMF showed sustained responses for 3 or 6 months than did placebo patients. MMF was well tolerated. Although MMF did not show an advantage on the primary end point, there seemed to be a beneficial treatment effect on several secondary end points, including time to response and duration of response. Thus, MMF may be a potentially useful agent in patients with mild or moderate pemphigus vulgaris.

Disturbances of hair follicle cycling lie at the heart of most hair growth disorders, and have dramatic effects on visible hair growth and shedding. The two common disorders due to aberration in hair follicle cycling are telogen and anagen effluvium. Though a lot of literature addresses the problem of telogen effluvium, there are not many reviews on anagen effluvium or anagen hair loss. Anagen effluvium is considered synonymous with chemotherapy-induced alopecia and other causes are rarely considered. In this review, we try to discuss the etiopathogenesis, clinical presentation, differentials, and management issues in anagen effluvium. Anagen effluvium is the abrupt loss of hairs that are in their growing phase (anagen) due to an event that impairs the mitotic or metabolic activity of hair follicle. Chemotherapy, radiation and toxic chemicals, and sometimes inflammatory diseases like alopecia areata and pemphigus are also capable of diminishing the metabolic activity of hair follicles resulting in anagen hair loss. Although it is reversible, and hair regrowth occurs after a delay of 1-3 months; sometimes it can lead to permanent alopecia and can be psychologically devastating with negative impact on individual perceptions of appearance, body image, sexuality, and self-esteem. For some patients, the emotional trauma may be so severe that it may lead to discontinuing or refusing therapy that might otherwise be beneficial. In such cases, a psychosomatic approach as well as empathic consideration of the patients concerns and fears as well as the provision of practical medical-aesthetic and styling tips are equally important and can be integrated in management.

Mucormycosis is an uncommon systemic mycosis affecting the immunocompromised individuals. It is usually caused by organisms of the genera Rhizopus and Mucor , although rarely other organisms have also been implicated. Mycoses due to these angioinvasive fungi have an acute onset, rapidly progressive course with high mortality rate. A rare and less well known is the chronic subtype of primary cutaneous mucormycosis (PCM). Herein, we report a case of PCM clinically presenting as a chronic, giant destructive plaque in a young immunocompetent male and coin the term chronic granulomatous mucormycosis. A clinicopathological classification for cutaneous mucormycosis is also proposed.

Self-healing juvenile cutaneous mucinosis (SHJCM) is a rare childhood disease with characteristic cutaneous and rheumatic manifestations. Cutaneous manifestations include a combination of nodules affecting peri-articular (especially interphalangeal joints) and head and neck areas; and linearly arranged ivory white papules over an erythematous indurated skin. Despite a benign course, an abrupt onset of symptoms with extensive cutaneous involvement often leads to parental anxiety, overenthusiastic evaluation and sometimes aggressive treatment. A peculiar cutaneous distribution in SHJCM including nodular lesions and periorbital edema, arthritis and arthralgia in a few cases, may simulate juvenile dermatomyositis. It is, therefore, important for dermatologists and pediatricians to be aware of this entity. In this report, we describe two cases of SHJCM and briefly review similarly reported cases in children.

Dexamethasone cyclophosphamide pulse (DCP) therapy is an established mode of treatment for pemphigus in India. To assess the therapeutic benefit of additional DCPs (phase II, consolidation phase) versus immediate oral cyclophosphamide, usually used in phase III (maintenance phase), after initial DCP therapy (phase I) and to assess which laboratory test (DIF or ELISA) will reflect the clinical relapse best. Nineteen newly recruited patients of pemphigus vulgaris (PV) received monthly DCPs in phase I and were then randomized into two groups. Group A (10 patients) received monthly DCPs for nine months and Group B (nine patients) received only oral cyclophosphamide for nine months. Direct immunofluorescence (DIF) and enzyme-linked immunosorbent assay (ELISA) were tested before starting DCP regimen, and at 0,3,6,9 months after randomization. Clinical relapse by the end of follow-up period occurred in only one patient in each group. In these cases, DIF became (again) positive before the relapse. No statistically significant difference between the two groups was found at three, six and nine months by ELISA indices and DIF grading. Although the DCP regimen is the standard therapy for pemphigus in India, we found no difference in the clinical outcome between patients receiving nine DCPs in phase II and patients shifted directly from phase I to III. Periodic testing using DIF and Dsg ELISA were found to be useful to monitor disease activity and predict a relapse. Further large scale studies are required to assess if patients can be shifted directly from phase I to III and maintained only on oral cyclophosphamide.

Pemphigus is a chronic epidermal immunobullous disease with potentially fatal outcome. The journey of literature on pemphigus in India has come a long way in last five decades. Pemphigus in Indian patients has unique genetic, clinical, and epidemiological differences from those in the Western countries. Corticosteroids remain the mainstay of treatment for pemphigus. Dexamethasone-cyclophosphamide pulse therapy has revolutionized the management of pemphigus in India and abroad for nearly 3 decades now. Corticosteroid-based treatment, along with adjuvants, has significantly brought down the high mortality rates that had been observed in precorticosteroid era. Present day research is largely based on elucidating the pathogenesis beyond the antidesmoglein antibodies, and newer diagnostic and treatment approaches. In this article, we review various aspects of literature on pemphigus in India, on Indians abroad, or literature from other countries that are considered relevant to the topic.

Background Pemphigus vulgaris (PV) is an autoimmune bullous disease caused by acantholysis of keratinocytes due to pathogenic desmoglein-3 autoantibodies. Role of vitamin D has been recently implicated in various autoimmune conditions due to its immunomodulatory effects on innate and adaptive immune responses. One of the key mechanisms of the immune regulation by vitamin D is through its anti-inflammatory effects by suppression of Th17 functions. Thus, vitamin D may be involved in pathogenesis of PV. In this study, the serum vitamin D, IL-17 and TGF-β levels in PV patients as well as healthy controls were estimated in order to understand the underlying immune mechanism involved in disease pathogenesis. Results This retrospective study included 30 biopsy proven PV patients’ sera. Ten age matched volunteers without any cutaneous or autoimmune conditions were recruited as healthy control (HC). Serum Vitamin D levels were measured using chemiluminescence, whereas IL-17 and TGF-β levels were determined using ELISA. All patients showed deficient vitamin D levels (11.1 ± 5.8 ng/ml). Moreover, all the PV patients had elevated serum IL-17 levels (210.7 ± 105.3), whereas it was not detectable in any (n = 10) of the healthy controls sera (ELISA sensitivity ≥ 8 pg/ml). The mean serum TGF-β concentration was also lower in patient sera as compared to healthy control, and the TGF-β/IL-17 ratio was drastically reduced in patients (30.30 ± 28), as compared to healthy controls (1363.34 ± 559.52). Conclusions Hypovitaminosis is common in North India, as ascertained by deficient levels in healthy controls, and was also consistently observed in PV patient. These low levels were not related to age or gender. The increased serum IL-17 and dramatic reduction in TGF-β/IL-17 ratio in diseased patients further indicate that dysregulation of the Treg/Th-17 axis of T effector cells may be of significance in pathogenesis of PV. Thus, the study indicates that vitamin D insufficiency may be a predisposing factor in PV, contributing through its role in any of the various adaptive immune mechanisms that regulate T cell functions in vivo . Thus, there is a need to further evaluate the Treg/Th-17 axis, as it may have an important role in disease progression.

Pemphigus is a chronic, muco-cutaneous autoimmune blistering disorder; two main variants being pemphigus vulgaris (PV) and pemphigus foliaceus (PF). PV is the most common subtype, varying between 75 to 92% of total pemphigus patients.
