GUERRERO, Gustavo Adolfo; GUERRERO, Luis Francisco  and  GONZALEZ, Tatiana. Non-lupus full house nephropathy in pediatrics: Case reports. Biomed. [online]. 2020, vol.40, n.2, pp.220-227.  Epub June 30, 2020. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.4863.

Full house nephropathy is defined as the simultaneous detection of IgA, IgG, IgM, C3, and C1q deposits by immunofluorescence, usually indicating lupus nephritis. There are patients with this immunofluorescence pattern, but with negative autoantibody serology, which means they cannot be diagnosed with systemic lupus erythematosus. Patients presenting with full house nephropathy but no other criteria for lupus are diagnosed as having nonlupus full house nephropathy.

Here, we describe two cases: A male patient who debuted with rapidly progressive glomerulonephritis and a female patient with nephrotic syndrome. Both had negative autoantibody serology, findings in the renal biopsy of class IV lupus nephritis and a full house immunofluorescence pattern. Histological findings in non-lupus full house nephropathy are similar to those in lupus nephritis and, probably, similar physiopathological bases. However, prospective studies are needed to determine risk factors and the renal prognosis and to make suggestions for specific treatments.

Keywords : Lupus nephritis; lupus erythematosus; systemic, kidney diseases.
