The problem of the anti-hepatitis B vaccination of patients with chronic obstructive lung disease (COPD) was discussed due to the lack of studies concerning the developing of the postvaccinal immunity, especially when vaccination is combined with the immunomodulating treatment. The data on the vaccination safety and its influence on the clinical course of COPD are also insufficient. Therefore, in this work we investigated the efficiency of the antihepatitis B vaccination in adults with chronic obstructive pulmonary disease under the treatment with the immunomodulating Affonoleikin drug. A total of 93 patients were tested including 59 patients with severe and moderate COPD (aged from 35 to 65 years). 34 of these 59 patients were vaccinated against hepatitis B (Kombioteh) according to 0-1-6 month scheme, and 25 of them were vaccinated against hepatitis B during the treatment with Affinoleikin. The control group, consisted of 34 healthy patients. Our study demonstrated good tolerance and high immune efficiency of the anti-hepatitis B vaccine. However, after the first vaccination the level of HBs-AT was below protective level in patients with COPD compared to healthy patients. Also, 64 to 70 % of patients with COPD were seronegative excluding the patients receiving the Affinoleikin treatment, whose antibody titer was protective after the first vaccine dose, but did not reach the level typical of healthy patients. After the second vaccination we detected low and medium protective antibody levels in 58.9% of patients from the 1st group, whereas 41% were seronegative. Introduction of the third vaccine-dose led to fast and significant increase in the antibody level mainly in high concentrations with 100% seroconversion in all patients. Combined antihepatitis B vaccination and Affinoleikin treatment in patients with COPD leads to faster biosynthesis of HBs- AT in protective concentrations and decrease of seronegative response, but it has no effect on frequency and type of general and local postvaccinal response.

Introduction: Despite the therapeutic effectiveness of biologics targeting immune cells or cytokines in patients with inflammatory arthritis, which reflects their pathogenic roles, an increased infection risk is observed in those undergoing biological treatment. However, there are limited data regarding the comparison of infection risks in inflammatory arthritis patients treated with non-biologics (csDMARDs), biologics (bDMARDs), including tumor necrosis factor (TNF) inhibitors and non-TNF inhibitors, or targeted synthetic (ts)DMARDs.Areas covered: Through a review of English-language literature as of 30 June 2019, we focus on the existing evidence on the risk of infections caused by bacteria, Mycobacterium tuberculosis, and hepatitis virus in inflammatory arthritis patients undergoing treatment with csDMARDs, bDMARDs, or tsDMARDs.Expert opinion: While the risks of bacterial and mycobacterial infection are increased in arthritis patients treated with csDMARDs, the risks are further higher in those receiving bDMARDs therapy, particularly TNF inhibitors. Regarding HBV infection, antiviral therapy may effectively prevent HBV reactivation in patients receiving bDMARDs, especially rituximab. However, more data are needed to establish effective preventive strategies for HBsAg-negative/HBcAb-positive patients. It seems safe to use cyclosporine and TNF inhibitors in patients with HCV infection, while those undergoing rituximab therapies should be frequently monitored for HCV activity.Abbreviations: ABT: abatacept; ADA: adalimumab; AS: ankylosing spondylitis; bDMARDs: biologic disease-modifying anti-rheumatic drugs; CKD: chronic kidney disease; COPD: chronic obstructive pulmonary disease; CS: corticosteroids; CsA: cyclosporine A; csDMARDs: conventional synthetic disease-modifying anti-rheumatic drugs; CZP: certolizumab; DAAs: direct-acting antiviral agents; DM: diabetes mellitus; DOT: directly observed therapy; EIN: Emerging Infections Network; ETN: etanercept; GOL: golimumab; GPRD: General Practice Research Database; HBV: hepatitis B virus; HBVr: HBV reactivation; HBsAg+: HBsAg-positive; HBsAg-/anti-HBc+: HBsAg-negative anti-HBc antibodies-positive; HCV: hepatitis C virus; HCQ: hydroxychloroquine: IFX: infliximab; IL-6: interleukin-6; JAK: Janus kinase; LEF: leflunomide; LTBI: latent tuberculosis infection; mAb: monoclonal antibody; MTX: methotrexate; OR: odds ratio; PsA: psoriatic arthritis; PMS: post-marketing surveillance; RA: rheumatoid arthritis; TNF: tumor necrosis factor; TNFi: tumor necrosis factor inhibitor; SCK: secukinumab; SSZ: sulfasalazine; TOZ: tocilizumab; RCT: randomized controlled trial; RR: relative risk; RTX: rituximab; 3HP: 3-month once-weekly isoniazid plus rifapentine; TB: tuberculosis; tsDMARDs: targeted synthetic disease-modifying anti-rheumatic drugs; UTK: ustekinumab; WHO: World Health Organization.
