Three patients are described who presented with a glomerulopathy suggestive of lupus nephritis in the absence of other clinical and biological evidence of systemic lupus erythematosus (SLE). Renal biopsies showed a ”full-house” immunofluorescence pattern and two patients also had cytoplasmic tubuloreticular inclusions by electron microscopy. All these patients developed antinuclear and anti-double-stranded DNA antibodies 3, 5, and 10 years after their original presentation. Subsequently, 1 patient also developed clinical symptoms of lupus. Reviewing all renal biopsies performed in our department, we found 14 additional patients who presented with a ”full-house” immunofluorescence glomerulonephritis in the absence of other features of SLE. After a mean follow-up of 5.8 years, these patients have not developed serological or clinical evidence of SLE. We conclude that a ”full-house” glomerulopathy in children may be the first symptom of SLE, especially when cytoplasmic tubuloreticular inclusions are detected. The appearance of other clinical and biological symptoms may be delayed by several years.
