Estado reaccional leprótico en una paciente con osteosarcoma de tobillo / No disponible

La lepra es una enfermedad infecciosa, poco transmisible, de evolución crónica, causada por el Mycobacterium leprae, que se caracteriza por afectar la piel, los nervios periféricos, la mucosa de las vías respiratorias superiores además de otras estructuras. Se ha subestimado su prevalencia y permanece siendo un problema de salud pública, detectándose aún nuevos casos cada año. Después de la introducción de la multiterapia MDT tanto prevalencia como incidencia han disminuido. En la actual investigación se hace la presentación de un caso clínico, paciente femenina, de 49 años, con diagnóstico de Lepra Dimorfa, que tiene antecedentes de haber sido amputada hace tres años de miembro inferior izquierdo por osteosarcoma de tobillo

Leprosy is an infectious disease with a chronic evolution and its etiological agent is Mycobacterium leprae. The disease affects skin, peripheral nerves, upper respiratory tract and other structures. Its prevalence has been underestimated and continues to be a public health problem in many countries. After the introduction of MDT, both prevalence and incidence declined. This study is a presentation of a clinical case of a 49 year old woman diagnosed of dimorphic leprosy and a history of amputation three years earlier due to osteosarcoma of the ankle

Histopathology of the lepromatous skin biopsy.

The histopathology of lepromatous skin varies according to the cell-mediated immunity of the host against Mycobacterium leprae. In tuberculoid and borderline tuberculoid leprosy, epithelioid noncaseating granulomas predominate, and acid-fast bacilli (AFB) are absent or only rarely present. In borderline lepromatous and lepromatous leprosy, the infiltrate is composed of macrophages with a vacuolar cytoplasm, lymphocytes, and plasma cells. AFB are numerous. Edema inside and outside the epithelioid granulomas, together with the appearance of large giant cells, are the main features of type 1 reactions. A conspicuous neutrophilic infiltrate in the subcutis with or without vasculitis is found in erythema nodosum leprosum. The main histopathologic features of leprosy and its particular forms are discussed in this review.

Clinical aspects of leprosy.

Leprosy is a chronic, infectious disease caused by Mycobacterium leprae. It mainly affects the peripheral nervous system, skin, and certain other tissues such as the reticulo-endothelial system, bones and joints, mucous membranes, eyes, testes, muscles, and adrenals. Leprosy clinical presentation varies from few to widespread lesions. In most patients, early leprosy presents as macular and hypopigmented lesions. This initial clinical presentation is known as indeterminate leprosy and occurs in individuals who have not developed cell-mediated immunity against M. leprae yet. The number of lesions depends on the genetically determined cellular immunity of the patient. Individuals presenting a vigorous cellular immune response and limited humoral immune responses to M. leprae, usually present few skin lesions. Without treatment, those patients tend to evolve into the polar tuberculoid or borderline tuberculoid form of leprosy. Due to the inability to mount an effective cellular-mediated response to M. leprae and the consequent hematogenous spread of the bacilli, some patients may present with numerous and symmetrically distributed hypochromic lesions. Without treatment these patients evolve to a nonresistant form of leprosy, polar lepromatous.

Chronic inflammatory joint disease revealing borderline leprosy.

Musculoskeletal symptoms are not infrequent in leprosy and, when inaugural, may be difficult to differentiate from other conditions, most notably rheumatoid arthritis. We report the case of a 24 year-old man with a 5 year history of intermittent inflammatory arthritis and fever. Physical findings and radiographs were normal initially. Several years later, he had severe wasting of the hand muscles, stocking-glove sensory loss, burn scars on the hands, and plantar ulcers. Electrophysiological test results indicated sensory-motor neuropathy with predominant demyelination. Laboratory tests showed inflammation without immunological abnormalities. A prominent endoneurial inflammatory infiltrate composed of mononuclear cells was seen on a nerve biopsy specimen, suggesting leprosy. A family study then revealed that the patient's aunt had been diagnosed with leprosy. Dapsone, clofazimine, and rifampin were given. The joint manifestations and laboratory tests for inflammation improved. However, no changes were noted in the neurological symptoms.

Perfil clinico-epidemiológico dos casos de hanseníase atentidos no Hospital Universitário em Campo Grande, Mato Grosso do Sul, de janeiro de 1994 a julho de 2005 / Clinical-epidemiological profile of leprosy patients assisted at the University Hospital of Mato Grosso do Sul Federal University, Campo Grande, MS, from January 1994 to July2005

Estudo descritivo, realizado a partir da coleta de dados de 192 fichas de notificação e controle da hanseníase, do total de pacientes atendidos no período de janeiro de 1994 a julho de 2005, no Ambulatório do Hospital Universitário da Universidade Federal de Mato Grosso do Sul, com o objetivo de traçar o perfil epidemiológico da hanseníase no grupo de pacientes estudados e gerar subsídios à política de controle da hanseníase. As variáveis estudadas constam da ficha de notificação e controle da hanseníase. Observou-se a predominância de casos no sexo masculino (62,5%); na faixa etária de 40 a 59 anos (45,8%); multibacilares (67,2%); da forma clinica dimorfa (35,9%) e virchowiana (27,6%). Setenta e três (73%) por cento dos casos foram avaliados em relação à incapacidade ao inicio do tratamento, encontrando-se 66,7% desses casos sem nenhum problema com as mãos, pés ou olhos e 33,3% com incapacidade ou deformidade ao início do tratamento.

Involvement of scalp in leprosy.

It is generally believed that hairy scalp is an immune zone for leprosy lesion, because of the higher temperature of the scalp, which is not suitable for the habitation of lepra bacilli. Here is a report of borderline tuberculoid leprosy involving scalp and the right side of the face. The patient also had features of type 1 lepra reaction and facial palsy on the right side.

A study of leprosy reactions in a tertiary hospital in Delhi.

A retrospective study of 531 leprosy patients was undertaken to study the profile of reactions in the post Multi-Drug-Therapy period in a tertiary hospital in Delhi. BT was the most common group. The prevalence of reactions was found to be 8.09% for the Type 1 and 4.70% for the Type 2 reactions for a male:female ratio of 2.2. The Type 1 reaction was most frequently observed in the BB group followed by BL, BT and LL groups respectively. More than half of the patients had reactions at the time of presentation. In only 39.8% of the patients did reaction follow Multi-Drug-Therapy. In 4.5% of the patients with Type 1 reactions (T1R), concomitant infections were noted. The most common presentation of T1R was cutaneous lesions (74.41%) followed by cutaneous lesions and neuritis (53.6%), neuritis alone (12.1%), and only edema of hands and feet (7.31%) respectively. The Type 2 reactions (T2R) presented chiefly as papulo-nodular (92%) lesions followed by pustulonecrotic (8%) lesions. Associated neuritis was found in 40% and periosteitis and iritis in 8% and 4%, respectively. In 8.6% of the patients with T2R, precipitating factors could be observed. The prevalence of deformities in patients with reaction was 25%, and was more common in females. Deformities were observed in 23.25% of the T1R patients and 28% of the T2R patients.

Ovarian function in female patients with multibacillary leprosy.

Eighty six adult female patients with multibacillary leprosy were included to study the sex hormone profile LH, FSH, and prolactin, as well as their gynecological events like menstrual function and fertility status. A third of the patients gave a history of irregularity of periods. The mean levels of LH and FSH were significantly higher in patients with multibacilary leprosy vis-à-vis the controls. Of the 24 married women with irregularity of periods, 12 (50%) were infertile. Seven of these patients had elevated levels of FSH and LH, almost reaching castration levels.

A case report of fatal dapsone-induced agranulocytosis in an Indian mid-borderline leprosy patient.

Leprosy affects facial nerves in a scattered distribution from the main trunk to all peripheral branches and neurolysis improves muscle function of the face.

Current literature rejects nerve release in leprous facial neuropathy and states that lesions are restricted to the peripheral zygomatic branches. Since there are approximately 500,000 patients with this disease throughout the world, we wanted to clarify the precise location of facial nerve's affection and the benefit of neurolysis. Our study showed that in patients with leprosy, the facial nerve's main trunk, the peripheral zygomatic branches, and all other branches were affected. Follow-up showed improvement in lagophthalmos and in misreinnervation, with no improvement in the control cohort. Nerve release improves muscle function in leprous facial neuropathy, provided surgery is performed on all affected segments. Intraoperative electroneurodiagnostics is an effective tool for detecting the most proximal site of lesion and ensuring effective surgery.

Paciente com reacao tipo I e tipo II e dez anos de seguimento / Type I and type II reactions in a patients with ten years of follow-up

Relata-se o caso de um individuo do sexo masculino, de 52 anos de idade, que desde 20 anos atras vinha apresentando sinais e sintomas de hanseniase multibacilar, mas so procurou tratamento apos 5 anos, quando apresentava manifestacoes de Eritema Nodoso Hansenico (ENH - Reacao tipo 1) inclusive com comprometimento articular. Instalado o tratamento (PQT/MB) o paciente passou a apresentar episodios de ENH, que se continuaram apos a alta medicamentosa alternando-se ou em concomitancia com episodios de reacao tipo 1 (reacao reversa) o que definiu como dimorfo. Assim permaneceu quase 10 anos, tendo apresentado, por algum tempo, esplenomegalia e sinais de hiperesplenismo. So melhorou, quando a deteccao de bacilos viaveis levou a reinstalacao da PQT. A discussao do caso ressalta alguns aspectos interessantes desta evolucao: 1) a demora no diagnostico leva pacientes dimorfos a adquirirem caracteristicas virchovianas com rica baciloscopia (virchovianos sub-polares); 2) estes pacientes tem maior possibilidade de albergarem bacilos persistentes que eventualmente se multiplicam e estimulam reacoes tipo I; 3) a alternancia de reacoes tipo 1 e tipo 2 pode indicar a participacao da imunidade celular no desencadeamento do ENH, onde a reacao granulomatosa romperia os infiltrados especificos regressivos, expondo antigenos intracelulares. Frente ao estado de hipersensibilidade humoral, haveria deposicao de complexos imunes e desencadeamento de reacao inflamatoria aguda; 4) a alta da PQT nao significa cura da hanseniase.
