ABSTRACT
Abstract: Approximately 10% of individuals do not respond to hepatitis B virus (HBV) vaccination, i.e. non-responders (NRs). We aimed to investigate the association of interleukin (IL)-4 and IL-12B gene polymorphisms with responsiveness to the HBV vaccine in Korean infants. Among 300 healthy infants (9-12 month), SNPs for the IL-4 gene (rs2243250, rs2070874, and rs2227284) and for the IL-12B gene (rs3213094 and rs17860508) were compared between subgroups in terms of the response to HBV vaccination. The percentages of NRs (< 10 mIU/mL), low-titer responders (LRs, 10-100 mIU/mL), and high-titer responders (HRs, ≥ 100 mIU/mL) were 20.3%, 37.7% and 42.0%, respectively. No SNPs differed in frequency between NRs and responders or between LRs and HRs. We divided the subjects into two groups according to the time interval from the 3rd dose of HBV vaccination to Ab quantification: > 6 months from the 3rd dose (n = 87) and ≤ 6 months from the 3rd dose (n = 213). In the ≤ 6 month subjects, rs2243250C and rs2227284G were significantly frequent in the lower-titer individuals (NRs + LR) than HRs (40.1 vs. 25.9%, p = 0.014 and 45.1 vs. 33.0%, p = 0.018, respectively), and the rs2243250C and rs2227284G frequencies were significantly different among the three subgroups (13.2 vs. 26.9 vs. 25.9%, p = 0.040 and 15.5 vs. 29.6 vs. 33.0%, p = 0.038, respectively). In conclusion, those results suggest that IL-4 gene polymorphisms may play a role in the response to the HBV vaccine in Korean infants.

ABSTRACT Objective: To investigate the safety and efficacy of allogeneic platelet-rich plasma (PRP) in rotator cuff repair . Methods: Seventeen patients with a full-thickness rotator cuff tear were included. Ten patients underwent arthroscopic rotator cuff repair with allogeneic, and seven patients with autologous PRP. Three PRP gels in a volume 3 ml each were applied between the torn end and the greater tuberosity. Clinical outcomes were assessed preoperatively and at a minimum of 2 years after surgery. Structural outcomes were evaluated with the presence of retear and the change of the cross-sectional area (ACT) of the supraspinatus . Results: Allogeneic PRP did not cause any adverse events during the follow-up period. There was no significant difference in the clinical outcome measures between the two groups (all p > 0.05). The retear rate was 33.3% and 25.0% in the allogeneic group and autologous group, respectively (p = 0.764). The change between the one-year postoperative and immediately postoperative ACT was not also significantly different between the two groups (p = 0.373) . Conclusion: Allogeneic PRP in arthroscopic rotator cuff did not cause any local or general complications and that has the efficacy comparable to autologous PRP with respect to the clinical and structural outcomes. Level of Evidence III, Retrospective Comparative Study.
RESUMO Objetivo: Investigar a segurança e eficácia do plasma rico em plaquetas alogênico (PRP) no reparo do manguito rotador. Métodos: Foram incluídos dezessete pacientes com ruptura da espessura total do manguito rotador. Dez pacientes foram submetidos a reparo artroscópico do manguito rotador com PRP alogênico e sete pacientes com PRP autólogo. Três géis de PRP de 3ml cada foram aplicados entre a extremidade lesionada e a tuberosidade maior. Os resultados clínicos foram avaliados no pré-operatório e no mínimo 2 anos após a cirurgia. Os resultados estruturais foram avaliados com a presença de nova ruptura e a alteração da área em corte transversal (ACT) do supra-espinhal. Resultados: O PRP alogênico não causou quaisquer eventos adversos durante o período de acompanhamento. Não houve diferença significativa nas medidas de resultados clínicos entre os dois grupos (todos os valores p> 0,05). A taxa de nova ruptura foi de 33,3% e 25,0% no grupo alogênico e grupo autólogo, respectivamente (p = 0,764). A alteração da ACT entre o pós-operatório de um ano e imediatamente no pós-operatório também não foi significativamente diferente entre os dois grupos (p = 0,373) . Conclusão: O PRP alogênico administrado por via artroscópica no manguito rotador não causou quaisquer complicações locais ou gerais e sua eficácia é comparável ao PRP autólogo no que diz respeito aos resultados clínicos e estruturais.
