Despite great improvement in patient and graft survival, the long-term morbidity and mortality in renal transplant recipients are still significant. Cardiovascular disease accounts for much of the mortality in long-term survivors; screening before the transplant procedure and adequate control of hypertension should help improve patient survival. Many of the gastrointestinal complications are due to overimmunosuppression and sepsis. Adequate management must include withdrawal of all immunosuppressive medications in order to save the patient's life. Liver disease is usually of viral origin; patients with chronic active hepatitis or cirrhosis should remain on dialysis. Chronic rejection is the major cause of graft loss in long-term survivors; it is unresponsive to antirejection treatment and its progression may be mediated by nonimmunologic mechanisms. Correctable problems such as renal artery stenosis and ureteral obstruction should be ruled out before a late deterioration in graft function is disregarded as chronic rejection. Post-transplant diabetes, osteonecrosis, cataracts, and nephrotoxicity are directly related to the various immunosuppressive drugs currently used. The lowest dose compatible with graft acceptance should help reduce the incidence of these nonfatal but significant complications. Recurrence of disease is a common histologic finding in many transplant recipients but, except for a few diseases such as HUS, FSGS, and oxalosis, it usually does not lead to graft failure. Successful transplantation restores fertility in many uremic patients. Adequate counseling on contraception is imperative in order to avoid unwanted pregnancies and to delay parenthood for at least 1 year. Current immunosuppressive agents are not teratogenic, no dose adjustments are necessary, and an ill-advised decrease in medication may precipitate a rejection episode. Premature delivery is the major problem in these patients and can be avoided by maintaining adequate graft function and controlling hypertension and infections. It is evident from this review that most of the long-term morbidity and mortality seen in renal allograft recipients are due to overimmunosuppression with sepsis or to side effects of the individual drugs, steroids being a common denominator in almost all cases. New immunosuppressive protocols must aim not only to improve patient and graft survival but also to avoid the many complications that limit the full rehabilitation of these patients.

The authors experienced an extremely rare case of secondary sclerosing cholangitis and portal hypertension developed as late complications of hemolytic uremic syndrome (HUS) owing to Escherichia coli O157:H7 in a 2-year-old boy. HUS after E coli O157 infection is the most frequent cause of acute renal failure in childhood and occasionally is accompanied by extrarenal complications such as encephalopathy, cardiomyopathy, ischemic colitis, and pancreatitis. Rarely, late colonic stenosis may develop secondary to the ischemic damage. Sclerosing cholangitis and subsequent cirrhosis with portal hypertension are very uncommon as late complications of HUS. To our knowledge, such a case has not been previously reported in the literature. J Pediatr Surg 36:1838-1840.

The aim of the study was to analyze the etiology, the factors for progression of chronic renal failure to end-stage-renal disease (ESRD), and the influence of ESRD on the survival rate among a cohort of 59 heart transplant patients (HTP) referred for the management of chronic renal failure (CRF). At the time of the first nephrology consultation (6 +/- 4.25 years after cardiac transplantation) the mean creatininemia was 261.5 +/- 99 micromol/L and mean creatinine clearance (Cockcroft formula) was 32 +/- 15 mL/min. The cause of CRF were calcineurin inhibitor toxicity in 38.9% of patients, vascular events in 15.2%, hemolytic uremic syndrome in 5%, membranous glomerulopathy in 3.3%, diabetes in two patients, focal/segmental glomerulosclerosis in 3.3%, renal hypoplasia in 1.7%, and unknown in 27%. Evolution to ESRD occurred in 38.9% of patients: 17 patients started hemodialysis, three peritoneal dialysis, and two received a preemptive kidney transplantation. Creatininemia (micromol/L) at the time of nephrology referral was 229.2 +/- 72.6 versus 315.8 +/- 113.4 (P < .001) and creatinine clearance (mL/min) was 34.9 +/- 15.1 versus 27.3 +/- 13.7 (P = .049) for patients with CRF versus ESRD, respectively. Both proteinuria (g/24 hours) of 1 +/- 2.2 versus 2.3 +/- 1.8 (P = .02) and tobacco use in 35.1% versus 54.4% (P = .045) were significantly associated with progression of CRF, while age at the time of heart transplantation, cause of cardiac failure and renal failure, high blood pressure, type 2 diabetes, dyslipidemia, alcoholism, cirrhosis, and cerebral vascular accident were not. Death occurred in 18 HTP: 50% of patients with ESRD and 18.5% of patients with CRF-a 2.6 relative risk of of death in HTP patients with ESRD compared with HTP with CRF only (P < .01).

Atypical hemolytic uremic syndrome (aHUS) is a rare and heterogenous disease caused by a disregulation of the alternative pathway of the complement cascade. Specifically, microvascular damage is produced that can lead to acute kidney disease, hemolytic anemia and thrombocytopenia. It accounts for 10% of all hemolytic uremic syndromes and can result in death or in end stage renal disease since the first episode. We can differentiate two forms of aHUS: a sporadic form (80%), affecting adult people, and a familial form (20%) that usually became manifest during infancy. In the acute phase of the disease, frequent and severe anemia requires multiple blood transfusions, exposing patients to the risk of catching an infective disease. HCV hepatitis is the most prevalent chronic hepatitis worldwide, with approximately 170 million chronically infected individuals - many of which are unaware of their condition. The evolution of the HCV infection is variable: almost 20% of patients spontaneously clear the infection over time (Anti HCV positive, HCV RNA negative patients); 80% of patients cannot control the virus and develop chronic infection (Anti HCV positive; HCV RNA positive patients) that can evolve into liver cirrhosis and hepatocellular carcinoma. The aim of this paper is to describe a clinical case of acute HCV hepatitis in a patient with aHUS treated with Eculizumab.
