Introduction

End-stage renal disease (ESRD) patients receiving maintenance

hemodialysis are at high risk of hepatitis B virus (HBV) infection and demonstrate

inadequate immune response to vaccination. our objective is to assess the antibody response (anti-HBs levels) of hepatitis B vaccinated

maintenance hemodialysis patients.

Methods

A cross-sectional observational analytical study was conducted at marine

city medical College hospital,Chittagong, Bangladesh for 34months of

period among 50 patients receiving maintenance hemodialysis for more than 4

months. Demographic and clinical data were collected, and post-vaccination anti-

HBs titers were measured. Patients were classified as high responders (anti-HBs ≥100

mIU/ml), poor responders (anti-HBs ≥10 to <100 mIU/ml) and non-responders (anti-

HBs <10 mIU/ml).

Results

The mean age of participants was 52 ± 10 years; 60% were male. The mean

duration of dialysis was 19.7 ± 7.7 months. The common causes of ESRD were

diabetic nephropathy (58%), glomerulonephritis (24%), hypertension (12%), and

others (6%). Overall, 38% were high responders, 26% poor responders, and 36% non-

responders, seroconversion rate was 66%. Mean anti-HBs titers were 663 ± 463

mIU/ml in high responders, 31.55 ± 23.24 mIU/ml in poor responders, and 3.23 ±

1.98 mIU/ml in non-responders. Age >50 years, presence of diabetes mellitus, and

lower serum albumin were significantly associated with poor or non response (p<0.05).

Conclusion

Development of protective antibody levels after hepatitis B vaccination

in maintenance hemodialysis patients were inadequate.Older age, diabetes and low

serum albumin were important predictors of poor response. Strategies such as

booster dosing and revaccination may improve seroconversion rates in this

population
