Adherence and immune response to revaccination following hematopoietic stem cell transplantation at a pediatric onco-hematology reference center. Transpl Infect Dis 2018; 20:e12903. [PMID: 29668078 DOI: 10.1111/tid.12903] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2017] [Revised: 03/14/2018] [Accepted: 03/18/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Revaccination after hematopoietic stem cell transplantation (HSCT) is necessary to compensate for the loss of immunological memory. The aims of this study were to evaluate the adherence to revaccination schedule and the humoral immune response to different vaccine antigens in HSCT pediatric and young adult patients. METHODS Patients submitted to HSCT for over 3 years were recruited. After written informed consent, a questionnaire was filled in, the vaccination card was analyzed, a blood sample was collected and tested by ELISA for diphtheria, Haemophilus influenzae type b (Hib), hepatitis A, hepatitis B, tetanus, measles, rubella, and varicella antibodies. RESULTS Sixty-three patients (mean age at HSCT, 10.7 years) were evaluated. Forty-one (65%) were male; 34 (54%) had allogeneic and 29 (46%), autologous HSCT. Complete adherence to diphtheria revaccination was found in 79.4% patients and seropositivity was found in 92% of those who completed the revaccination schedule; for Hib, 68.3% adherence and 95.3% seropositivity were observed; for hepatitis A, 63.5% adherence and 92.5% seropositivity; for 3 doses of hepatitis B, 86.8% adherence and 79.2% seropositivity; for tetanus, 79.4% adherence and 100% seropositivity; for measles and rubella, 17.5% adherence and 100% seropositivity; for varicella, 7.9% adherence and 100% seropositivity. The existence of a Vaccination Center for Special Immunobiologicals in patients' municipality was positively associated with completed vaccine schedule; on the other hand, chronic GVHD was negatively associated with revaccination adherence. CONCLUSION Hematopoietic stem cell transplantation patients showed good seropositivity rates after complete vaccination schedule. However, a low coverage rate was observed for live attenuated antigens.

Abstract
BACKGROUND/AIMS Hepatitis B virus (HBV) continues to be one of the most important viral pathogens in humans. Surface (S) protein is the major HBV antigen that mediates virus attachment and entry and determines the virus subtype. Mutations in S gene, particularly in the "a" determinant, can influence virus detection by ELISA and may generate escape mutants. Since no records have documented the S gene mutations in HBV strains circulating in Saudi Arabia, the current study was designed to study sequence variation of S gene in strains circulating in Saudi Arabia and its correlation with clinical and risk factors. PATIENTS AND METHODS A total of 123 HBV-infected patients were recruited for this study. Clinical and biochemical parameters, serological markers, and viral load were determined in all patients. The entire S gene sequence of samples with viral load exceeding 2000 IU/mL was retrieved and exploited in sequence and phylogenetic analysis. RESULTS A total of 48 mutations (21 unique) were recorded in viral strains in Saudi Arabia, among which 24 (11 unique) changed their respective amino acids. Two amino acid changes were recorded in "a" determinant, including F130L and S135F with no evidence of the vaccine escape mutant G145R in any of the samples. No specific relationship was recognized between the mutation/amino acid change record of HBsAg in strains in Saudi Arabia and clinical or laboratory data. Phylogenetic analysis categorized HBV viral strains in Saudi Arabia as members of subgenotypes D1 and D3. CONCLUSION The present report is the first that describes mutation analysis of HBsAg in strains in Saudi Arabia on both nucleotide and amino acid levels. Different substitutions, particularly in major hydrophilic region, may have a potential influence on disease diagnosis, vaccination strategy, and antiviral chemotherapy.

High Prevalence of Hepatitis B Virus Infection in Young Adults in Ternate, Eastern Indonesia. Am J Trop Med Hyg 2015; 93:1349-55.

Abstract
The incidence of hepatitis B virus (HBV) infection has been declining thanks to the universal hepatitis B infant immunization program. Nevertheless, young adults born before the program implementation might have acquired HBV in early childhood or remain susceptible to infection. This study aimed to evaluate hepatitis B epidemiology in asymptomatic young adult population in Ternate, eastern Indonesia. Serum samples of 376 subjects (aged 17-25, mean 19.82 ± 1.69 years; male/female 138/238) were screened for HBV parameters serologically (HBV surface antigen [HBsAg]; its antibody [anti-HBs]; anti-core antigen [anti-HBc]), and molecularly (HBV DNA). HBsAg, anti-HBc, anti-HBs, and HBV DNA prevalence were 15.7%, 36.2%, 24.2%, and 27.9%, respectively, with male predominance. Of all subjects, 13.0% were HBsAg negative with detectable HBV DNA (occult hepatitis B [OHB]), and 56.4% showed negativity for all seromarkers. This population showed high hepatitis B prevalence with substantial occurrence of OHB. However, a high percentage of the population were still susceptible and at risk of HBV infection. This study emphasizes the necessity to improve prevention strategies to screen and manage HBV carriers, including the adoption of catch-up or booster vaccination targeted to young adult populations. Investigations on the roles of host-virus interactions associated with OHB and its implications are warranted.
