Abstract

Histoid Leprosy is a variant of lepromatous leprosy with characteristic clinical and histopathological features. Usually it is occured in lepromatous patients who relaps after dapsone monotherapy, in those with dapsone resistance , sometimes even after multidrug treatment, or at times, de novo with characteristic clinical and histopathological features. A 36 years old male, originated from Papua, visited to the skin outpatient clinic with translucent shiny nodules on the left elbow and thumb for the last 18 months. The nodules were multiple, painless and firm. There were nasal congestion, tickening of ear lobes and loss of eye brows. Patient did not have any history of previous antileprotic treatment. Routine blood examination was normal. Bacteriological examination of slit skin smear revealed acid-fast bacilli of Bacterial Index 4+ and Morfologic Index 10%. Histopathology of skin suggested lepromatous leprosy of histoid type with characteristic interlacing bundles of spindle shaped cells. Anti-PGL1 antibody (ELISA) revealed high titer of IgM (>5.300 u/ml) and also IgG anti PGL-1 (>5.300 u/ml). Polymerase chain reaction examination test to detect M.leprae was positive and direct sequencing of M.leprae isolate shows no mutation, which means no resistancy to MDT treatment. Treatment with MDTWHO regiment give clinical improvements and the histoid lesions disappered after 3 months treatment.The histoid form of leprosy in this case developed without any prior treatment of anti leprotic drugs ( de novo ). Some theoretical aspects of the patho-mechanism of histoid leprosy are discussed.

Abstract

East Java province still has some pocket of leprosy endemic areas. In order to solve the problem, molecular typing will make it feasible to study the transmission pattern of Mycobacterium leprae in leprosy endemic area. The present study is to analyze the presence of M.leprae DNA in the environment and to study variation number of TTC repeats and their distribution. Poteran Island is located in Madura, East Java and was chosen because this island has a high prevalence of leprosy and remains stable for the last five years. All samples were analyzed by PCR and the numbers of TTC repeats were confirmed by direct sequencing. Of all collected samples, 26.4% isolates of water resources (24); 61.9% nasal swabs (26); and 35.3% skin tissues (24) are positives. No statistically difference in the pattern distribution of TTC repeats between skin tissues of patients and nasal swab of households contact (p=0.594); also distribution of TTC repeats between skin tissues of leprosy patients and those of water resources (p=0.441); and distribution of TTC repeats between nasal swab of households contact with water resources (p=0.906). It means that the transmission of M.leprae in leprosy endemic area has closely related in 3 aspects: agent, host & environment.
