Evaluation of anti-hepatitis B antibody among nurse's aid conservatory students of IRIAF Besat Hospital

Hepatitis B virus is the cause of acute and chronic hepatitis، cirrhosis and hepatocellular carcinoma. In the present، the only secure way to prevent hepatitis B is vaccination، but the vaccination is not 100% affective. Considering the importance of this، the efficacy of vaccination in high risk groups and health-care workers are at risk being involved with all types of hepatitis viruses. For reduction of hepatitis B infection among hospital staff these groups should be vaccinated against HBV besides using other standards for HBV prevention. The purpose of this study is to evaluate the anti-hepatitis B antibody among students of nurse’s aid school in Be''sat Hospital. Anti-hepatitis B antibody levels were measured using ELISA in 64 nurse’s aid students. the vaccination history of study population was unclear. 37 (57. 8%) cases were non-immune and 27 (42. 2%) cases were immune against HBV. Our results showed similarity with other studies. Several factors affected HBV immunization such as age، genetics، obesity، and smoking. This study showed that more than half of the people are non-immune. It should be noted that these people are in continuous contact with their classmates and patients so they should be evaluated for HBs antibody titer in different intervals.
