Summary: | Abstract Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune inflammatory disease. However, some patients may exhibit a histological pattern of kidney injury, with characteristics indistinguishable from lupus nephritis, but without presenting any extrarenal symptoms or serologies suggestive of SLE. Such involvement has recently been called non-lupus full-house nephropathy. The objective is to report a series of clinical cases referred to the Laboratory of the Federal University of Maranhão that received the diagnosis of "full-house" nephropathy unrelated to lupus, upon immunofluorescence and to discuss its evolution and outcomes. Non-lupus full-house nephropathy represents a diagnostic and therapeutic challenge, because it is a new entity, which still needs further studies and may be the initial manifestation of SLE, isolated manifestation of SLE or a new pathology unrelated to SLE.
Resumo O lúpus eritematoso sistêmico (LES) é uma doença inflamatória crônica autoimune multissistêmica. Alguns pacientes, contudo, podem exibir um padrão histológico de lesão renal, com características indistinguíveis da nefrite lúpica, porém sem apresentar quaisquer sintomas extrarrenais ou sorologias sugestivas de LES. Tal acometimento tem sido recentemente denominado nefropatia “full-house” não relacionada ao lúpus. O objetivo é relatar uma série de casos clínicos encaminhados ao Laboratório da Universidade Federal do Maranhão que receberam o diagnóstico de nefropatia “full-house” não relacionada ao lúpus à imunofluorescência e discutir sua evolução e desfechos. A nefropatia “full-house” não relacionada ao lúpus representa um desafio diagnóstico e terapêutico por ser uma entidade nova, que ainda necessita de maiores estudos e pode ser a manifestação inicial do LES, manifestação isolada do LES ou uma patologia nova não relacionada ao LES. |
