Oro-facial manifestations in lepromatous leprosy patients in Central India: clinical findings from a cross-sectional study.

OBJECTIVES: To clinically evaluate the oro-facial manifestations in lepromatous leprosy patients undergoing multidrug therapy in Central India. MATERIALS AND METHODS: Two hundred patients from 2 leprosy treatment centers in Central India who satisfied the diagnostic criteria set by the WHO (2006-2010) committee on leprosy were included in the study. To avoid bias, only patients who started the multi-drug treatment regimen less than 1 year ago were included. All the patients were examined for the presence of oral and facial manifestations. To confirm that the oro-facial manifestations were not due to HIV co-infection, serological diagnostic tests including ELISA, Immunocomb, and Tri-dot were performed. RESULTS: Majority of the patients (n = 189) exhibited oral (n = 145) and/or facial (n = 147) manifestations. The most common oral lesions were found to be fissuring and depapillation of the tongue followed by fibrosis and loss of uvula. Among the facial manifestations, facial skin lesions and loss of eyebrows were most prevalent followed by sagging of facial skin and facies leonine. CONCLUSION: The facial manifestations of leprosy are quite common, readily recognizable, and relatively specific to the disease. Thus, the presence of facial manifestations, especially with co-existing oral lesions must prompt the clinician to mandate further investigations to confirm the diagnosis. CLINICAL RELEVANCE: As evidenced by the present study, facial manifestations and oral lesions are an integral part of leprosy. In addition to being a diagnostic parameter, facial manifestations and oral lesions could potentially be used to monitor the disease progression and treatment outcome.

Hematological alterations in lepromatous leprosy: A cross-sectional observational study.

BACKGROUND: Dapsone has been the mainstay for the treatment of leprosy since its discovery in the 1940s. However, hematological disturbances are not uncommon in leprosy patients on daily dapsone therapy. Hence, the present study was conducted to document the hematologic alterations observed in lepromatous leprosy patients treated with Dapsone 100 mg daily. METHODOLOGY: A cross-sectional observational study was conducted amongst 32 lepromatous leprosy patients treated with Dapsone 100 mg daily. A complete hemogram was conducted for all the study recruits. The test results were compared against the standard average values for adults for the given variables. The one sample t-test was employed to compare the difference between the study values and the standard normal values for adults. The statistical significance was considered at p < 0.05. RESULTS: The study reveals a marked decrease in hemoglobin concentration in patients on dapsone, 100 mg daily. Other hematological alterations found were reduced platelet count, reduced mean platelet volume, reduced Hematocrit, reduced Mean Corpuscular hemoglobin, reduced Mean Corpuscular hemoglobin concentration. (p < 0.05). CONCLUSION: Treatment of lepromatous leprosy with 100 mg daily Dapsone therapy may lead to hematological alterations. These findings are suggestive of dapsone-induced hemolysis.

Epidemiological aspects of leprosy.

Leprosy is a bacterial infection causing severe disfigurement of the affected individual. It is considered as an ancient disease affecting humanity since thousands of years and also has tremendous stigma associated with it. It is known as a neglected tropical disease. In spite of all the efforts, the disease remains a major healthcare distress in many underdeveloped and developing countries like India and Brazil. Thus, to understand the disease and implement various strategies successfully, one need to understand the epidemiological aspect of the disease along with various operational factors influencing the epidemiological data. Thus, the present paper describes the various epidemiological facts and figures of leprosy along with the suggestions and measures to tackle this global ailment.

Current updates on dental perspectives of leprosy - Revisited.

The present review summarizes the current updates on dental perspectives on leprosy and the affording factors that are responsible for the prevalence of caries and periodontal diseases in leprosy. It also highlights immunopathological phenomena and reactional episodes of leprosy that occur due to daedal interactions between the perio-odontopathic bacteria and M. leprae. In addition, a brief introduction, historiography, classification and clinicopathological aspects are also been covered.
