Lupus-like glomerulonephritis, defined by immunohistologic features and absence of serologic evidence of SLE, is not an uncommon form of glomerular disease in HIV-infected patients undergoing a renal biopsy. Renal outcomes in these patients were poor, although this may be due largely to most patients presenting with advanced disease.

High citrate diet preserved renal function and delayed progression of renal disease in ClC-5 knockout mice even in the apparent absence of stone formation. We conclude from this that long-term control of hypercalciuria is an important factor in preventing renal failure in these mice.

Granulosa cell tumor (GCT) is a rare neoplasm hallmarked by a very indolent course and late recurrences. Although numerous clinical and pathological parameters have been implicated as prognostic factors for GCT, their role remains controversial. We performed a retrospective study at our institution where we identified 48 patients with GCT from our tumor registry. Demographic and clinical course information was recorded from the medical record. Twenty of 48 formalin-fixed, paraffin-embedded blocks were retrieved from archived specimens. Pathological parameters such as nuclear atypia, mitotic count, Ki-67 index using immunohistochemistry, and quantitative DNA ploidy were performed. DNA aneuploidy by quantitative method was associated with patients' overall survival. The degree of nuclear atypia, mitotic count, Ki-67 index, and DNA aneuploidy was not predictive of tumor recurrence. Multi-institutional collaboration is imperative to create a comprehensive national database for investigation into ways that may better indicate prognosis in these patients.
