S.R. Rathinam FAMS PhD Uveitis service Aravind Eye Hospital Madurai. LeprosyOcular Erythema nodosum leprosum
History • 45 year old male patient with lepromatous leprosy • he was advised treatment several times, but because of • recurrent ENL reaction, patient never took proper treatment.
First Examination • OS: leproma with hypopyon • aqueous tap, staining for Mycobacterium lepra + • hypopyon is reported but very rare in leprosy
Treatment • Standard multi drug anti leprosy treatment • 20 mg oral steroids • 600 mg Rifampicin and 300 mg Clofazimine on day 1 of every month • 100 mg Dapsone daily and • 50 mg Clofazimine for 12-24 months
Follow up - Day 7 • developed very severe type 2 reactions, • experienced fever, malaise, and polyarthralgia as well as an abrupt onset of numerous tender, erythematous nodules over the face, extremities and over the trunk. • This is termed erythema nodosum leprum (ENL) and tends to occur • with poor cellular immunity but strong humoral immunity to M. leprae, • more specifically in patients with high bacillary load
Follow up – Day 7 • severe ocular ENL resulted in ocular perforation • because of severe pain the globe was enucleated • histopathological staining
Histopathology • limbal region LE • Polymorphonuclear cells in ENL
Treatment Options • Corticosteroids are highly useful for type 1 and type 2 reactions, but • Thalidomide is the most effective agent to treat severe forms of type 2 reactions • Thalidomide was not available freely but would have helped this patient
Uveitis was found in 56% In HPE Clinically 5-6 %
Type III Hypersensitivity • Erythema nodosum leprosum (ENL) is induced in a Type 2 lepra reaction • Type 2 lepra reactions are acute inflammatory complications that often present as medical emergencies during the chronic course of treated or untreated Hansen's disease
