Comparative StudyLaparoscopic or open surgery for living donor nephrectomy.
The anterior extraperitoneal approach for living donor nephrectomy has been used in more than 700 living cases in the unit and proved to be safe for the donor. In 1998, laparoscopic nephrectomy was introduced as an option when technically feasible. We found it essential to investigate the consequences of the new technique. ⋯ Laparoscopic nephrectomy is safe. Less post-operative pain is a definite advantage for the donor.

Meta Analysis Comparative StudyDo the Y-set and double-bag systems reduce the incidence of CAPD peritonitis? A systematic review of randomized controlled trials.
Peritonitis is the most frequent serious complication of continuous ambulatory peritoneal dialysis (CAPD). It has a major influence on the number of patients switching from CAPD to haemodialysis and has probably restricted the wider acceptance and uptake of CAPD as an alternative mode of dialysis. This systematic review sought to determine if modifications of the transfer set (Y-set or double-bag systems) used in CAPD exchanges are associated with a reduction in peritonitis and an improvement in other relevant outcomes. ⋯ Double-bag systems should be the preferred exchange systems in CAPD.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of continuous haemofiltration vs intermittent haemodialysis on systemic haemodynamics and splanchnic regional perfusion in septic shock patients: a prospective, randomized clinical trial.
Parameters of splanchnic regional perfusion, like intramucosal pH (pHi) and pCO(2) (pCO(2)i), may predict outcome in septic shock patients. Continuous venovenous haemofiltration (CVVH) has been considered beneficial in haemodynamically unstable septic shock patients. In a prospective, randomized, clinical study, we investigated whether CVVH, in comparison to intermittent haemodialysis (IHD), is able to improve splanchnic regional perfusion in critically ill patients. ⋯ Despite different changes of systemic haemodynamics between CVVH and IHD, CVVH did not improve parameters of splanchnic regional perfusion like pHi, pCO(2)i or pCO(2) gap in septic shock patients.

Several therapeutic approaches have been tried in patients with membranous nephropathy. Corticosteroids have been largely used, but a meta-analysis of the available controlled trials did not show any benefit of corticosteroids either in favouring remission of the nephrotic syndrome or in preventing renal dysfunction. Controversial results have been obtained with cytotoxic agents. ⋯ A number of non-controlled studies and a randomized trial also showed the efficacy of cyclosporine in reducing proteinuria. In many but not all cases, proteinuria reappeared when cyclosporine was stopped. In conclusion, although the treatment of membranous nephropathy remains difficult, some therapeutical approaches have proved to favour remission and protect renal function

Leptospirosis is a re-emerging infectious disease, affecting both animals and humans worldwide. Multiple organ involvement may be encountered in leptospirosis, and early renal involvement is very common, characterized by tubulo-interstitial nephritis and tubular dysfunction. All 12 patients diagnosed in Chang Gung Memorial Hospital (Taiwan) between 1997 and 1999 had acute renal failure, with five patients requiring dialysis. ⋯ To understand the mechanism behind tubular injuries by leptospira infection, outer membrane proteins (OMPs) extracted from pathogenic leptospira were given to tubular cells in culture. Our in vitro experiment showed that OMPs of pathogenic leptospira activate nuclear NFkappaB binding and stimulate downstream inducible nitric oxide (iNOS), monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor-alpha (TNF-alpha) expression. These results indicate that leptospiral infection may induce tubulo-interstitial nephritis through a toxic component in the outer membrane followed by expression of inflammatory genes.
