Abstract

Objectives: Hepatitis B virus (HBV) vaccination is efficient inthe normal population, whereas lower humoral response ratesin immunosuppressed patients. Biological agents used in thetreatment of several diseases in recent years are a significantcause of immunosuppression in patients. In this study we aimed toevaluate the efficacy of double-dose HBV vaccination at months 0,1, 2, and 6 in patients using biological agents.Materials and Methods: The patients who were using biologicalagents and seronegative for HBV received double-dose HBVvaccine (40 µg) on months 0, 1, 2 and 6, and response rates wereassessed. Patients with anti-HBs titers >10 mIU/mL one monthafter completion of the vaccine plan were regarded as vaccineresponsive.Results: Eighty-four patients were evaluated. Forty patients(47.4%) were men and 44 (52.4%) were women. The mean ageof the patients was 43.1±12.5 years. The most common underlyinginflammatory rheumatic disease was ankylosing spondylitis at51.2% (n=43). The most commonly used biological agent wasadalimumab at 36.9% (n=31). Vaccine response was achieved in85.7% (n=72) of the patients, while no response was achievedin 12 patients (14.3%). Sex, comorbidities, type of underlyinginflammatory disease and biological agents had no effect on vaccineresponse.Conclusion: Administration of 40 µg HBV vaccine at months 0, 1,2, and 6 to HBV seronegative patients using biological agents wasfound to be effective. This efficacy was found to be independent ofthe type of biological agent, the time of onset of the biological agentand the length of use of the biological agent.

Özet

Amaç: Hepatit B virus (HBV) aşısı normal popülasyonda etkin iken, immünosüpresif hastalarda humoral yanıt oranları daha düşüktür. Son yıllarda birçok hastalıkta kullanılan biyolojik ajanlar önemli bir immünosüpresyon nedenidir. Bu çalışmada, biyolojik ajan kullanan hastalarda 0, 1, 2 ve 6. aylarda çift doz HBV aşılamasının etkinliğinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Biyolojik ajan kullanan ve HBV için seronegatif olan hastalara 0, 1, 2 ve 6. aylarda çift doz (40 µg) HBV aşısı uygulanarak yanıt oranları değerlendirildi. Aşı şeması tamamlandıktan bir ay sonra bakılan anti-HBs titresi >10 mIU/mL olan hastalar aşı yanıtlı olarak kabul edildi. Bulgular: Seksen dört hasta değerlendirildi. 40 hasta (%47,4) erkek ve 44 hasta (%52,4) kadındı. Hastaların yaş ortalaması 43,1±12,5 idi. Altta yatan enflamatuvar romatizmal hastalıklarından en sık görüleni %51,2 (n=43) oranında ankilozan spondilit idi. Biyolojik ajanlardan en sık %36,9 (n=31) oranında adalimumab kullanılmıştı. Çalışmada hastaların %85,7’sinde (n=72) aşı yanıtı sağlanırken 12 hastada (%14,3) aşı yanıtı alınamadı. Cinsiyetin, komorbiditelerin ve altta yatan enflamatuvar romatizmal hastalığın ve biyolojik ajanın türünün aşı yanıtını etkilemediği saptandı. Sonuç: Biyolojik ajan kullanan HBV seronegatif hastalarda; 0, 1, 2 ve 6. aylarda 40 µg HBV aşı uygulamasının etkin olduğu saptanmıştır. Bu etkinliğin biyolojik ajanın türünden, biyolojik ajana başlama zamanından ve biyolojik ajanı kullanma süresinden bağımsız olduğu görülmüştür.
