Mycophenolate Mofetil for the Management of Autoimmune Bullous Diseases

Treatment options for autoimmune bullous dermatoses other than systemic steroids: A systematic review and network meta-analysis

Autoimmune blistering diseases can eventually cause life-threatening complications if left untreated. Although there is no cure for these bullous diseases; their therapy is based on suppressing the immune system to cease the de novo formation of the generated antibodies. The current study aimed to assess the safety and efficacy of using standing alone alternative therapies beyond systemic steroids for management of autoimmune bullous diseases. We searched six literature databases for both randomized and quasi-randomized clinical trials that assessed the efficacy of drugs other than systemic steroids in autoimmune bullous diseases. Outcomes were calculated as odds ratios with 95% confidence-interval. We used the R software to perform conventional and network meta-analyses with a frequentist approach. The network ranking order for 629 bullous pemphigoid patients, from the best to the worst was, clobetasol propionate cream (40 mg; (P-score = .87), clobetasol propionate cream (10-30 mg; P-score = .77), nicotinamide plus tetracycline (P-score = .56), steroids (P-score = .29) and doxycycline (P-score = .01). Limitations of this study are the small sample of the included studies except for blister trial and lack of randomization in most trials. To conclude, Combined doxycycline and nicotinamides are safer and more effective option for extensive bullous pemphigoid patients than the usual use of systemic steroids. For limited disease, topical corticosteroid (40 mg/d) use provides a safer and better response modality than the other proposed treatments.

Rare Vesiculopustular Eruptions of the Neonatal Period

Numerous disorders present with vesiculopustular eruptions in the neonatal period, ranging from benign to life-threatening. Accurate and prompt diagnosis is imperative to avoid unnecessary testing and treatment for benign eruptions, while allowing for adequate treatment of potentially fatal disorders. In this review, we highlight several rare blistering diseases of the newborn. A diagnostic approach is outlined to provide clinicians with a framework for approaching a neonate with vesicles, pustules, or ulcers.

A Case of Acute Pemphigus Vulgaris Relapses Associated with Cocaine Use and Review of the Literature

Pemphigus is a bullous autoimmune disease that affects the skin and mucous membranes. It is very difficult to establish the etiology and the triggering factors that influence reactivations in pemphigus vulgaris (PV). The case of a 33-year-old male with chronic history of intranasal cocaine consumption is presented in this report. We present the clinical case of the patient, followed for a total of 86 weeks, with ten relapses secondary to probable cocaine use. The patient was admitted to the emergency department after presenting polymorphic dermatosis characterized by blisters, vesicles, and excoriations extending from the oral cavity to the thorax, and to the inguinal and genital regions, affecting approximately 35 % of the body surface area with a score of 56 on the Pemphigus Skin Disorder Index. Skin biopsies were compatible with PV diagnosis. The patient had clinical improvement with a combination of methylprednisolone 500 mg intravenously (IV) and cyclophosphamide 500 mg IV every 15 days, along with prednisone 50 mg orally (PO) q24 h and mycophenolic acid 500 mg PO q6 h. Persistent cocaine use is highly likely to be the factor triggering lesion reactivation and responsible for the torpid evolution. We cannot definitively conclude whether the change from azathioprine to mycophenolic acid after the tenth relapse was the adjuvant medication responsible for the end of the consolidation phase and complete remission on therapy. This case study could potentially serve as a guide for management of patients who continuously persist with cocaine use, leading to a clinical picture refractory to multiple therapeutic schemes.
