ANCA associated vasculitis and chronic lymphocytic leukemia: a rare association.

The aim of the present work is to discuss the report of a patient who had simultaneous diagnosis of two rare diseases, vasculitis related to antineutrophil cytoplasmic antibodies and chronic lymphocytic leukemia. Both are diseases that may be multisystemic and thus cause diagnostic confusion. In this case, the patient had renal, pulmonary, hematological, and ocular symptoms, which could be secondary to vasculitis both as to leukemia. With the aid of imaging studies, pathological studies, immunohistochemistry and immunophenotyping, we conclude that it was a combination of the two diseases. There are other reports in literature of this association, however, with pANCA positive, this is the first report of chronic lymphocytic leukemia associated with cANCA positive vasculitis.

Hemochromatosis simulating rheumatoid arthritis: a case report.

This is a report of a patient who had a previous diagnosis of rheumatoid arthritis, nonerosive, rheumatoid factor negative, that despite the therapeutic approach presented progressive worsening of the articular and general condition. After extensive research, she had a diagnosis of hemochromatosis. Joint symptoms are common manifestations in hemochromatosis. The arthropathy of hemochromatosis may resemble inflammatory arthropathy mimicking RA, particularly in the most common sites as 2nd and 3rd metacarpophalangeal. Radiologically are observed decreased joint space, subchondral sclerosis, cyst formation and chondrocalcinosis. Treatment with disease modifying drugs for rheumatoid arthritis tend to worsen the clinical picture, since the liver is the major site of deposition of iron in hemochromatosis and these medications are known to be hepatotoxic. Phlebotomy treatment for hemochromatosis is apparently ineffective in reversing the articular manifestations, which requires the association with iron chelating drugs. Due to the apparent difficulty in differentiating between the two diseases, a screening profile of iron in patients with rheumatoid arthritis with atypical progression is necessary.

Vasculite associada à ANCA e leucemia linfocítica crônica: uma rara associação / ANCA associated vasculitis and chronic lymphocytic leukemia: a rare association

O presente trabalho tem por objetivo uma discussão acerca do relato de um doente que teve o diagnóstico simultâneo de duas doenças pouco frequentes, a vasculite relacionada ao anticorpo anticitoplasma de neutrófilos e a leucemia linfocítica crônica. Ambas são doenças que podem apresentar envolvimento multissistêmico e, assim, causar confusão diagnóstica. Neste caso, o doente apresentou comprometimento renal, pulmonar, hematológico e ocular, que poderiam ser secundários tanto à vasculite quanto à leucemia. Com auxílio de exames de imagem, estudos anátomopatológicos, imuno-histoquímica e imunofenotipagem concluímos tratar-se de uma associação das duas doenças. Há, na literatura, outros relatos desta associação, no entanto, com pANCA positivo; este é o primeiro relato de leucemia linfocítica crônica associada à vasculite com cANCA positivo.

Hemocromatose simulando artrite reumatoide: relato de caso / Hemochromatosis simulating rheumatoid arthritis: a case report

Este é um relato de uma paciente que teve diagnóstico prévio de artrite reumatoide, não erosiva, fator reumatoide negativo, que apesar da terapêutica instituída apresentava piora progressiva do quadro articular e do estado geral. Após extensa investigação, apresentou diagnóstico de hemocromatose. Sintomas articulares são manifestações frequentes na hemocromatose. A artropatia da hemocromatose pode assemelhar-se a artropatias inflamatórias imitando a AR, particularmente nos sítios mais comuns, como 2ª e 3ª metacarpofalangeanas. Radiologicamente são observadas diminuição do espaço articular, esclerose subcondral, formação de cistos e condrocalcinose. O tratamento com drogas modificadoras de doença para artrite reumatoide tende a piorar o quadro clínico, uma vez que o fígado é o principal sítio de depósito de ferro na hemocromatose e essas medicações são sabidamente hepatotóxicas. O tratamento com flebotomia para hemocromatose é aparentemente ineficaz na reversão das manifestações articulares, sendo necessária a associação com medicações quelantes de ferro. Devido à dificuldade aparente de diferenciação entre as duas patologias, faz-se necessária uma triagem no perfil do ferro em pacientes com diagnóstico de artrite reumatoide com evolução atípica.

[Hemorrhagic stroke related to snakebite by bothrops genus: a case report]. / Acidente vascular cerebral hemorrágico associado à acidente ofídico por serpente do gênero bothrops: relato de caso.

This research reports a clinical case of hemorrhagic stroke due to envenomation by bothrops snakebite associated with severe hypertension. Although bothrops snakebites are frequent in the State of Pará, such associations are uncommon, requiring specialized and early management to avoid severe complications.

Acidente vascular cerebral hemorrágico associado à acidente ofídico por serpente do gênero bothrops: relato de caso / Hemorrhagic stroke related to snakebite by bothrops genus: a case report

Este trabalho tem como objetivo relatar um caso de acidente vascular cerebral hemorrágico, associado à acidente ofídico por serpente do gênero bothrops e hipertensão arterial sistêmica grave. Apesar do ofidismo botrópico ser frequente no Estado do Pará, tais associações são incomuns, necessitando de uma abordagem especializada e precoce, visando menores complicações.

Acidente vascular cerebral hemorrágico decorrente de ofidismo por bothrops sp: relato de caso / Hemorrhagic stroke due to bothrops sp snakebite: case report

Objetivo: relatar um caso de hemorragia cerebral consequente a ofidismo por serpente Bothrops sp. Relato do caso: mulher de 62 anos vítima de acidente ofídico por serpente do gênero Bothrops, evoluiu com quadro de hemorragias sistêmicas, déficit neurológico focal e rebaixamento do nível de consciência. Tomografia de crânio revelou hematomas cerebrais intraparenquimatosos. Recebeu soroterapia antibotrópica e suporte clínico, apresentando boa recuperação. Considerações Finais: distúrbios hemorrágicos decorrente de ofidismo são causas potenciais de acidente vascular cerebral.

Purpose: to report a case of cerebral hemorrhage resulting from ophidism by Bothrops sp snake. Case report: a 62-year-old woman, victim of snakebite by Bothrops sp, evolved with systemic hemorrhage, focal neurologic deficit and declining level of consciousness. Tomography of the brain revealed cerebral intraparenchymal hematoma. The victim received bothropic antivenom and clinical support, presenting good recovery. Final considerations: bleeding disorders caused by snakebite are potential causes of stroke.

Predisposition to idiopathic thrombocytopenic purpura maps close to the major histocompatibility complex class I chain-related gene A.

Idiopathic thrombocytopenic purpura (ITP) is an autoimmune condition with poorly known etiology, characterized by platelet destruction. Genetic association studies of this disease are scarce, discrepant, and restricted to major histocompatibility complex (MHC) polymorphisms. Hence, a case-control study was conducted with an aim to map the MHC to IPT susceptibility using HLA-B and nine microsatellite loci encompassing MHC class I, II, and III regions. We compared the allelic frequencies in samples of unrelated healthy controls and ITP patients. After correction for multiple tests, only allele MICA*183, also known as A5.1, demonstrated an association, resulting in the identification of a major predisposing region close to STR-MICA. This result may highlight the putative functional role of MICA in the immune response to ITP.
