Non-lupus full-house nephropathy: a case series

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.
