ABSTRACT

Abstract: A 39-year-old woman presented with prominent and painful livedo reticularis lesions spreading on her upper and lower extremities. Histopathologically, the small-to medium-sized arteries in the deep dermis and subcutis showed necrotizing vasculitis with cellular infiltration, suggesting cutaneous polyarteritis nodosa. The serum levels of inflammatory markers normalized with aspirin 100mg/day and prednisolone 10mg/day within 2 months, and there was no other skin or organ involvement over 18 months of follow up. However, serious refractory skin depressions and pigmentation remained after two years of treatment. This suggests the importance of early and aggressive therapy for cutaneous polyarteritis nodosa to prevent unsightly skin sequel, as well as control of disease activity.

ABSTRACT

Livedoid vasculopathy (LV) is a chronic and recurrent disease consisting of livedo reticularis and symmetric ulcerations, primarily located on the lower extremities, which heal slowly and leave an atrophic white scar ("atrophie blanche"). Neurological involvment is rare and presumed to be secondary to the ischemia from vascular thrombosis of the vasa nervorum. Laboratory evaluation is needed to exclude secondary causes such as hyper-coagulable states, autoimmune disorders and neoplasms. We present two patients with a rare association of peripheral neuropathy and LV, thereby highlighting the importance of a multidisciplinary approach to reach the correct diagnosis. .


Vasculopatia livedoide é uma doença crônica e recorrente caracterizada por livedo reticular e úlceras simétricas nos membros inferiores, que cicatrizam e deixam uma cicatriz branca atrófica ("atrophie blanche"). Envolvimento neurológico é raro e está provavelmente associado a isquemia pela trombose dos vasa nervorum. Avaliação laboratorial é indicada com o intuito de excluir causas secundárias como estados de hipercoagulabilidade, doenças autoimunes e neoplasias. Apresentamos dois pacientes com uma rara associação de vasculopatia livedoide com neuropatia periférica, enfatizando a importância de uma abordagem multidisciplinar na busca do diagnóstico correto.

ABSTRACT

OBJETIVO: Relatar o caso de uma criança com diagnóstico de síndrome do anticorpo antifosfolípide associada à trombocitopenia grave e realizar uma revisão de literatura sobre o assunto. DESCRIÇÃO DO CASO: Criança de nove anos e oito meses de idade com trombocitopenia grave associada a anticorpo anticardiolipina positivo. Os dados foram coletados por meio de anamnese, exame físico e exames complementares da paciente. O diagnóstico foi determinado de acordo com os critérios estabelecidos para a síndrome antifosfolípide, associados às manifestações mais comuns na faixa etária pediátrica: livedo reticular e trombocitopenia. COMENTÁRIOS: A síndrome do anticorpo antifosfolípide é uma doença incomum na população pediátrica e suas manifestações clínicas, com a redução do número de plaquetas, devem ser consideradas.


OBJECTIVE: To report the case of a child diagnosed with antiphospholipid syndrome associated with severe thrombocytopenia, and to review the literature on the subject. CASE DESCRIPTION: Child aged nine years and eight months old with severe thrombocytopenia associated with a positive anticardiolipin antibody. Data were collected by clinical history, physical examination, and laboratorial exams. Diagnosis was confirmed according to criteria established for the antiophospholipid syndrome, associated with the presence of the most common manifestations of the syndrome in children: livedo reticularis and thrombocytopenia. COMMENTS: The antiphospholipid syndrome is an uncommon pediatric disease, and clinical manifestations such as decreased platelet number should be considered.


OBJETIVO: Relatar el caso de un niño con diagnóstico de síndrome del anticuerpo antifosfolípido asociado a trombocitopenia grave y realizar una revisión de literatura sobre el tema. DESCRIPCIÓN DEL CASO: Niño de nueve años y ocho meses de edad, con trombocitopenia grave asociada a anticuerpo anticardiolipina positivo. Los datos fueron recogidos por medio de historia, examen físico y exámenes complementarios de la paciente internada en un hospital de Curitiba, en Paraná (Brasil). El diagnóstico fue determinado conforme a los criterios establecidos para el síndrome antifosfolípido, asociados a las manifestaciones más comunes en la franja de edad pediátrica: livedo recticular y trombocitopenia. COMENTARIOS: El síndrome del anticuerpo antifosfolípido es una enfermedad poco común en la población pediátrica, y su manifestación con reducción del número de plaquetas debe ser considerada.

ABSTRACT

A anemia hemolítica autoimune (AHAI) é uma doença na qual são produzidos anticorpos diretamente contra as glicoproteínas adsorvidas na superfície da membrana dos eritrócitos. Algumas medicações e outras associações têm sido implicadas. Descrevemos e discutimos um caso de livedo reticular associado à AHAI tratado com transplante de células-tronco de sangue periférico (TCTSP) e que entrou em total remissão por 10 anos. Após esse período, a paciente apresentou recaída, foi tratada com anticorpo anti-CD20 (rituximabe), e atualmente encontra-se em total remissão. O papel do TCTSP e o uso de rituximabe no tratamento de AHAI serão discutidos neste relato de caso.


Autoimmune hemolytic anemia (AIHA) is a disease where patients produce antibodies against erythrocytes directed towards membrane glycoproteins adsorbed onto the erythrocyte surface. Drugs and other associations have been implicated. It is described and discussed a case of livedo reticularis associated with AIHA treated with peripheral blood stem cell transplantation (PBSCT) that went into full remission for 10 years. After that period the patient relapsed and was treated with antibody anti-CD20, rituximab, and is now in full remission. The role of PBSCT and rituximab in the treatment of AIHA will be discussed.
