Comparing immune response of intradermal low dose versus intramuscular high dose

of hepatitis B vaccination in hemodialysis patients

Ali Momeni, Mohammad Rajaei

Abstract

•BACKGROUND: Hepatitis B is the most important cause of cirrhosis in developing

countries. Hemodialysis patients are susceptible to infection due to repeated

contact with dialysis machines and blood products. The aim of this study was to

compare the efficacy of intradermal low dose with intramuscular high dose

hepatitis B vaccination in hemodialysis patients.

•METHODS: In a cross-sectional study on 24 hemodialysis patients that not

responded to conventional method of vaccination in this center (double dose in

0, 1 and 6 months) and have antibody titer less than 10 mu/ml were enrolled to

intramuscular or intradermal group, randomly. In intradermal (ID) group 10 µg

(0.5 ml) recombinant vaccine, every 2 weeks to 6 months and in intramuscular

(IM) group 40 µg (2 ml) at 0, 1, 2, and 6 months were prescribed and antibody

titer were checked after 1 and 3 months of the end of vaccination.

•RESULTS: Mean HBS antibody titer in patients was 4.4 ± 3.1 mu/ml at the

beginning of study (minimum: 1.1 mu/ml and maximum: 9.2 mu/ml) and after 1 month

and 3 months, mean HBS antibody were 190.4 ± 59 and 223.3 ± 83.9, respectively

(p < 0.001). After one month, in intradermal and intramuscular groups, mean HBS

antibody was 198.8 ± 75.6 mu/ml and 181.2 ± 61.8 mu/ml, respectively (p = 0.5)

and after 3 months it was 230 ± 76 mu/ml and 216.2 ± 94.3 mu/ml, respectively (p

= 0.83).

•CONCLUSIONS: Antibody titer was high (> 50 mu/ml) in two groups after 1 and 3

months of vaccination and no significant difference was found between the 2

groups. Therefore, two methods of vaccination (high dose IM and low dose SC) are

equally effective and the selection of vaccination method is based on health

policy.
