A real-world study of low-dose thalidomide in severe erythema nodosum leprosum highlighting its mechanistic rationale in a resource-constrained target population.

Background: Corticosteroids remain the main therapy in erythema nodosum leprosum (ENL), and long-term usage in chronic or recurrent ENL is a cause of significant morbidity and mortality. Thalidomide exerts dramatic effect in controlling ENL and helps reduce the dose of steroids, but the cost is a hindrance to its usage.

Methods: Patients of ENL (steroid naïve and steroid-dependent) were recruited over a 1-year period.

Case Report: Successful Outcome of Primary Infertility with Multidrug Therapy in a Long-Standing Case of Hypogonadism Resulting from Lepromatous Leprosy: Shattering the Dogma of Irreversible Infertility in Leprosy.

We present a case of primary infertility with features of hypogonadism in a male patient with lepromatous leprosy who had remained undiagnosed for 3 years. On investigation, azoospermia and deranged gonadotropin levels with normal serum testosterone were noted and the patient was initiated on multibacillary-multidrug therapy with the primary aim of treating the disease. Although the cutaneous lesions improved within 6 weeks, remarkably infertility was reversed in 2 months-with concomitant normalization of luteinizing hormone, follicle stimulating hormone, and sperm count-an outcome that was unexpected.

Case Report: Rapid Response to Low-Dose Thalidomide in a Case of Severe Steroid Recalcitrant Erythema Nodosum Leprosum.

Erythema nodosum leprosum (ENL), or type 2 lepra reaction, presents with crops of evanescent, tender erythematous nodules accompanied by fever, arthralgia, malaise and organ-specific manifestations and is seen in borderline and lepromatous leprosy. The drugs approved for ENL include nonsteroidal anti-inflammatory drugs, systemic steroids, thalidomide and clofazimine. The management of ENL is challenging because long-term steroid use leads to steroid dependence.
