A systematic review on the epidemiological data of erythema nodosum leprosum, a type 2 leprosy reaction.

ABSTRACT:

Multiple episodes are frequent and suppression requires high doses of immunosuppressive drugs. Global occurrence is unknown.

Methodology/principal findings

Systematic review of evidence on ENL incidence resulted in 65 papers, predominantly from India (24) and Brazil (9), and inclusive of four reviews. Average incidences are based on cumulative incidence and size of study populations (n>100). In field-based studies 653/54,737 (1.2%) of all leprosy cases, 194/4,279 (4.5%) of MB cases, and 86/560 (15.4%) of LL cases develop ENL. Some studies found a range of 1
