Background. The study was performed to investigate the prevalence, awareness and the risk factors of chronic kidney disease (CKD) in the community population in Shanghai, China.Methods. A total of 2596 residents were randomly recruited from the community population in Shanghai, China. All were screened for albuminuria, haematuria, morning spot urine albumin-to-creatinine ratio and renal function. Serum creatinine, uric acid, cholesterol, triglyceride and haemoglobin were assessed. A simplified MDRD equation was used to estimate the glomerular filtration rate (eGFR). All studied subjects were screened by kidney ultrasound. Haematuria, if present in the morning spot urine dipstick test, was confirmed by microscopy. The associations among the demographic characteristics, health characteristics and indicators of kidney damage were examined.Results. Two thousand five hundred and fifty-four residents (n = 2554), after giving informed consent and with complete data, were entered into this study. Albuminuria and haematuria were detected in 6.3% and 1.2% of all the studied subjects, respectively, whereas decreased kidney function was found in 5.8% of all studied subjects. Approximately 11.8% of subjects had at least one indicator of kidney damage. The rate of awareness of CKD was 8.2%. The logistic regression model showed that age, central obesity, hypertension, diabetes, anaemia, hyperuricaemia and nephrolithiasis each contributed to the development of CKD.Conclusion. This is the first Shanghai community-based epidemiological study data on Chinese CKD patients. The prevalence of CKD in the community population in Shanghai is 11.8%, and the rate of awareness of CKD is 8.2%. All the factors including age, central obesity, hypertension, diabetes, anaemia, hyperuricaemia and nephrolithiasis are positively correlated with the development of CKD in our studied subjects.

MMF has higher efficacy in inducing remission in severe LN than pulsed intravenous therapy with CYC. Induction therapy with MMF is also associated with fewer side effects than induction therapy with CYC. Compared with AZA, MMF also is an alternative for maintenance therapy of severe LN without significant difference in the prognosis or risks of amenorrhoea and herpes zoster.

Background/Aims: Primary antineutrophil cytoplasmic antibodies (ANCA)-associated systemic vasculitis (AASV) used to have poor prognosis, and renal involvement is its most common manifestation. Few studies have been published focusing on AASV patients with poor prognosis. Methods: From 1997 to 2006, 101 patients with ANCA-associated renal vasculitis (70 microscopic polyangiitis, MPA; 14 Wegener’s granulomatosis, WG; 3 Churg-Strauss syndrome, CSS; 14 renal limited vasculitis, RLV) were diagnosed in Shanghai Ruijin Hospital and 26 deaths were recorded among them. Patients’ data were retrospectively analyzed. Results: Patients with WG, MPA and RLV made up for 23.1% (6/26), 65.4% (17/26) and 11.5% (3/26) of all deaths. No deaths were observed among CSS patients. Infection alone accounted for 13 deaths. Infection together with pulmonary involvement of active vasculitis accounted for 3. Organ-specific involvement of active vasculitis alone caused 8 deaths. Others died of acute myocardial infarction or gastric carcinoma. Compared with patients who survived, nonsurvivors had more severe renal insufficiency and older age (p < 0.01). There was no significant difference regarding clinical presentation at diagnosis and cause of death between patients who survived first remission-induction treatment and those who did not. Infection remained the major cause of death. Conclusion: Infection is the major cause of death in patients with ANCA-associated renal vasculitis, and treatment response might not correlate to severity of disease in patients with poor prognosis. Rational use of immunosuppressants could improve the prognosis.
