Investigation of chronic kidney diseases from inpatients with cerebrovascular diseases in Shanghai / 中华肾脏病杂志

ABSTRACT

ObjectiveTo investigate the prevalence of chronic kidney diseases (CKD) from inpatients with cerebrovascular diseases in Shanghai district. MethodsInpatients with cerebrovascular diseases from neurology department of five hospitals in Shanghai from Jun. 2007 to Feb. 2008 were recruited . All the patients were respectively diagnosed by brain CT, CTA, MRI, MRA and TCD. Laboratory data included urinary microalbumin-to-creatinine ratio (ACR), routine urinalysis, fasting plasma glucose, 2-hour-postprandial plasma glucose, Scr, uric acid, etc. All the serum creatinine samples were uniformly tested in central laboratory of Shanghai Ruijin Hospital.Glomendar filtration rate (GFR) was estimated by complicated MDRD equation and CKD stage was classified according to K/DOQI guidelines. ResultsA total of 1014 hospitalized patients with cerebrovascular diseases were enrolled during the observation period, with M/F ratio of 559/455 and mean age of (68.56±12.17) years. Cerebrovascular diseases included ischemic stroke (708 cases), hemorrhagic stroke (197 cases) and transient cerebral ischemie attack (TIA) (109 cases). Microalbuminuria (MAU) was detected in 11.2%, while 24.8% patients had proteinuria. The prevalence of CKD was 47.7%. The percentage of these inpatients in CKD stage 1 to 5 was approximately 6.90%, 14.69%, 21.60%, 2.56% and 1.97% respectively. The Logistic regression model showed that the risk factors of short-term (<30 days) prognosis were albuminuria, hyperglycemia (fast glucose) and anemia. ConclusionsThe prevalence of CKD in inpatients with cerebrovascular diseases was 47.7% in Shanghai. It is significant to evaluate CKD among patients with cerebrovascular diseases, especially to use the screening of ACR in the early stage.
