Acute renal impairment is uncommon in SARS but carries a high mortality. The acute renal impairment is likely to be related to multi-organ failure rather than the kidney tropism of the virus. The development of acute renal impairment is an important negative prognostic indicator for survival with SARS.
Lupus nephritis is associated with a 6-fold increase in mortality compared with the general population. Lupus patients who develop ESRD have a 26-fold excess in the risk of death, which is more than twice the risk associated with malignancy or cardiovascular disease in these patients.
Manystudies have shown that kidney transplant recipients have a higher incidence of cancers when compared with general population. However, most data on the posttransplant malignancies (PTM) are derived from Western literature and large population-based studies are rare. There is also lack of information about the posttransplant cancer-specific mortality rate. We conducted a population-based study of 4895 kidney transplants between 1972 and 2011, with data from the Hong Kong Renal Registry. Patterns of cancer incidence and mortality in our kidney transplant recipients were compared with those of the general population using standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) respectively. With 40 246 person-years of follow-up, 299 PTM was diagnosed. The SIR of all cancers was 2.94 (female 3.58 and male 2.58). Non-Hodgkin lymphoma (NHL), kidney, and bladder cancers had the highest SIRs. The overall SMR was 2.3 (female 3.4 and male 1.7) and the highest SMR was NHL. The patterns of PTM differ among countries. Increases in cancer incidence can now translate into similar increases in cancer mortality. NHL is important in our kidney transplant recipients. Strategies in cancer screening in selected patient groups are needed to improve transplant outcomes.
Objective The ISPD 2005 guidelines for peritonitis recommend antibiotic prophylaxis for patients undergoing colonoscopy with polypectomy while on continuous ambulatory peritoneal dialysis (CAPD) but there is little literature to support this recommendation. This study aimed to look into the risks and outcomes of peritonitis after colonoscopy in CAPD patients. Patients and Methods All records of flexible colonoscopy performed on our CAPD patients from January 1994 to January 2006 were retrieved. Demographic and clinical data, use of antibiotics before colonoscopy, endoscopic findings, procedure performed, and peritonitis data were analyzed. Results 77 CAPD patients underwent 97 colonoscopies. No peritonitis developed in the 18 cases where antibiotics were given before colonoscopy. Among those without antibiotic prophylaxis, 4 episodes of peritonitis occurred within 24 hours after the procedure and 1 occurred 5 days later. All responded to intraperitoneal antibiotics. Colonic biopsy and polypectomy were not associated with more peritonitis (2 in 41 with biopsy vs 3 in 38 without biopsy, p = 0.67; 1 in 30 with polypectomy vs 4 in 49 without polypectomy, p = 0.64). Conclusion The risk of peritonitis after colonoscopy without antibiotic prophylaxis was 6.3%. All peritonitis episodes responded to intraperitoneal antibiotics. Colonic biopsy or polypectomy did not appear to increase the risk of peritonitis. Although statistically not significant when compared with patients without antibiotic prophylaxis, we observed no peritonitis after colonoscopy in patients that were given antibiotics for prophylactic purposes or for other reasons. The efficacy of prophylactic antibiotics would be better defined by large randomized trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
