ABSTRACT
OBJECTIVE To analyze the characteristics of nosocomial infections,risk factors and prevention measures in patients with chronic severe hepatitis B.METHODS A retrospective review of the medical records of 354 patients with chronic severe hepatitis B admitted between Jan 2006 and Dec 2006 was performed.RESULTS The incidence of nosocomial infection in patients with chronic severe hepatitis B was 16.67% and mainly infection sites consisted of abdominal cavity(40.32%),and upper respiratory tract(22.58%).The most common infection(47.46%) was occurred during the period of hospitalization 15-30 days after and the most commonly pathogens were Gram-negative bacilli(68.75%).The infection risk factors were associated with invasive operation,hypoalbuminemia,endotoxemia,advanced age,antibiotics application and decrease in cell immune function.CONCLUSIONS It is important for the patients with chronic severe hepatitis B to strengthen management on related risk factors in order to prevent nosocomial infection effectively.
ABSTRACT
Objective To investigate the infection status of nanobacteria on patients of chronic hepatopathy and hepatocellular carcinoma,and evaluate the clinical value of PCR.Methods In sera of 68 cases of chronic hepatitis B(CHB),56 chronic severe hepatitis B(CSHB),66 cirrhosis of liver(CL)and 23 hepatocellular carcinoma(HCC),nanobacteria were detected by immunohistochemistry stain(IHC),Transmission Electron Microscopy(TEM)and polymerase chain reaction(PCR),compared with 40 healthy people.Results The positive rates of PCR were 27.69%,50.00%,61.29%,52.38% and 5.00% in patients with CHB,CSHB,CL,HCC and normal control respectively(P
