The peritonitis rate was relatively low in the present investigation. Elderly patients were at higher risk of peritonitis episodes. Peritonitis independently predicted technique failure, in agreement with other reports. However, contrary to previous studies, all-cause mortality was better in patients experiencing peritonitis than in those free of peritonitis. The underlying mechanisms of this presumptive "peritonitis paradox" remain to be clarified.

Background: Glomerular "full-house" immunofluorescence staining commonly indicates lupus nephritis. However, some non-lupus nephropathy also can present with a "full-house" immunofluorescence pattern mimicking lupus nephritis. The goal of this study is to define the clinicopathological spectrum of originally non-lupus "full-house" nephropathy. Methods: Records of 24 patients with "full-house" nephropathy in the absence of clinical or serological evidence of systemic lupus erythematosus (SLE) at the time of renal biopsy were abstracted for demographics, clinical presentation, laboratory data, renal biopsy findings, and clinical follow-up. Results: The clinicopathological diagnoses included membranous glomerulonephritis (GN) (46%), IgA nephropathy (21%), membranoproliferative GN (12.5%), postinfectious GN (12.5%), C1q nephropathy (4%), and unclassified mesangial GN (4%). No one had endothelial tubuloreticular inclusions. One patient originally diagnosed as IgA nephropathy developed anti-DNA antibody and another one patient with membranous GN developed hypocomplementemia 8 months and 10 months after renal biopsy, respectively. The two patients also developed clinical symptoms of lupus subsequently. Conclusions: There was a broad spectrum of glomerular histological findings in non-lupus "full-house" nephropathy. The possibility of "full-house" nephropathy preceding the emergence of overt systemic lupus erythematosus remained to be elucidated.

Time to first peritonitis is significantly correlated with clinical outcomes of peritonitis patients with early peritonitis patients having poor prognosis. Patients with shorter time to first peritonitis were prone to having a higher peritonitis rate.

In patients with stages 3-5 CKD, mean corpuscular volume was associated with all-cause mortality, cardiovascular disease mortality, and infection-associated mortality, independent of other factors. The underlying pathophysiologic mechanisms warrant additional investigation.
