Borderline tuberculoid leprosy in childhood onset systemic lupus erythematosus patient.

Leprosy is a contagious and chronic systemic granulomatous disease caused by the bacillus Mycobacterium leprae. To our knowledge, no case of leprosy in a childhood-onset systemic lupus erythematosus (c-SLE) patient has been reported. For a period of 31 years, 312 c-SLE patients were followed at the Pediatric Rheumatology Unit of our University Hospital. One of them (0.3%) had tuberculoid leprosy skin lesions during the disease course and is here reported. A 10-year-old boy from Northwest of Brazil was diagnosed with c-SLE based on malar rash, photosensitivity, oral ulcers, lymphopenia, proteinuria, positive antinuclear antibodies, anti-double-stranded DNA, anti-Sm and anti-Ro/SSA autoantibodies. He was treated with prednisone, hydroxychloroquine and intravenous cyclophosphamide, followed by mycophenolate mofetil. At 12-years-old, he presented asymmetric skin lesions characterized by erythematous plaques with elevated external borders and hypochromic center with sensory loss. Peripheral nerve involvement was not evidenced. No history of familial cases of leprosy was reported, although the region where the patient resides is considered to be endemic for leprosy. Skin biopsy revealed a well-defined tuberculoid form. A marked thickening of nerves was observed, often destroyed by granulomas, without evidence of Mycobacterium leprae bacilli. At that time, the SLEDAI-2K score was 4 and he had been receiving prednisone 15 mg/day, hydroxychloroquine 200 mg/day and mycophenolate mofetil 3 g/day. Paucibacillary treatment for leprosy with dapsone and rifampicine was also introduced. In conclusion, we have reported a rare case of leprosy in the course of c-SLE. Leprosy should always be considered in children and adolescents with lupus who present skin abnormalities, particularly with hypoesthesic or anesthesic cutaneous lesions.

Leprosy in transplant recipients: report of a case after liver transplantation and review of the literature.

Leprosy still is an important public health problem in several parts of the world including Brazil. Unlike the diseases caused by other mycobacteria, the incidence and clinical presentation of leprosy seems little affected in immunosuppressed patients. We report the first case, to our knowledge, of a liver transplant patient who developed multi-bacillary leprosy. The patient presented with papules and infiltrated plaques with loss of sensation suggestive of leprosy 3.5 years after living-related liver transplantation for autoimmune hepatitis. A skin biopsy showing non-caseating macrophagic granulomas, neuritis, and intact acid-fast bacilli on Fite-Faraco stain, confirmed the diagnosis of borderline lepromatous leprosy. The donor of the liver did not show any evidence of leprosy. During follow-up, the patient presented 2 episodes of upgrading leprosy type I reactions, 1 mild before leprosy treatment, and 1 moderate 3 months after receiving standard multi-drug treatment (rifampicin, clofazimine, and dapsone). These reactions were accompanied by increase in liver function tests, especially of canalicular enzymes. This reaction occurred despite the patient's triple immunosuppression regimen. The moderate reaction was successfully treated with further immunosuppression (prednisone, 0.5 mg/kg). Currently, the patient is asymptomatic, off leprosy medication, with routine liver transplant follow-up. The dilemmas in diagnosis and management of such a case are discussed and the literature on leprosy in transplant recipients is reviewed.

Acute methemoglobinemia induced by dapsone / Metahemoglobinemia aguda induzida por dapsona: relato de caso no tratamento para hanseníase

Acute methemoglobinemia is an uncommon but potentially treatable disorder in witch patient can present with dramatic signs and symptoms. The early diagnostic and treatment are essentials to prevent this fatal medicine reaction.

Two patients coinfected with Mycobacterium leprae and human immunodeficiency virus type 1 and naive for antiretroviral therapy who exhibited type 1 leprosy reactions mimicking the immune reconstitution inflammatory syndrome.

Two case reports of patients with human immunodeficiency virus type 1 (HIV-1) infection who developed leprosy are presented. Both developed type 1 leprosy reactions in the absence of antiretroviral therapy. Reactions have been described for a number of HIV-1- and Mycobacterium leprae-coinfected patients and have been considered to be part of an immune reconstitution inflammatory syndrome (IRIS) since the reactions were usually linked to the administration of highly active antiretroviral therapy. The reports of our two patients suggest that the type 1 reactions in patients with leprosy and HIV may not always be an IRIS manifestation but may be akin to the classical reactional state described for the natural course of leprosy infection, which occurs in leprosy patients due to the fluctuations of the antimycobacterial immune response, whether they are coinfected with HIV or not.

[Physical disabilities in Hansen's disease at the time of diagnosis. I. Disability evaluation]. / Incapacidades físicas em hanseníase no momento do diagnóstico. I--Avaliação das incapacidades.

The evaluation of the physical disabilities at the moment of the hanseniasis diagnosis was carried out through the clinical and epidemiological forms of the 8,915 cases recorded in the State of São Paulo, Brazil, from 1981 to 1983. The records of the physical disabilities were studied by three different methods: the disabilities at their highest grade, the disabilities' grade index achieved from the arithmetic mean of the added values of the different disability grades, and the absolute disabilities frequency. The study suggested that the maximum grade was the best evaluation method of the physical disabilities at the moment of the diagnosis, being an important indicator for the evaluation of prevention efforts and of the hanseniasis control.

[Physical disabilities in Hansen's disease at the time of diagnosis. II. Indicators for evaluating a Hansen's disease control program]. / Incapacidades físicas em hanseníase no momento do diagnóstico. II--Indicador para avaliação do programa de controle da hanseníase.

The evaluation of physical disabilities caused by hanseniasis at the moment of the diagnosis, was carried out through the clinical and epidemiological forms of the 8,915 cases recorded in the State of São Paulo, Brazil, from 1981 to 1983. The resulting data showed that the disabilities' evaluation at the moment of the diagnosis is an important index for the hanseniasis control programme specially when related to other variable elements involved in the diagnosis of the hanseniasis situation.
