Clin Infect Dis:干预疗法或促进婴儿期HIV感染者的安全行为

来源:生物谷 2012-11-10 12:54

2012年11月10日 讯 /生物谷BIOON/ --近日,刊登在国际杂志Clinical Infectious Diseases上的一篇研究报告中,来自国外的研究者指出随着在婴儿期感染HIV的人群逐渐经历青春期以及成年期,在其进行性行为之前,需要对其进行健康行为的引导来避免HIV的传播以及感染。

这项研究中,研究者对330名年轻人进行调查发现,其均有未进行保护措施的性行为,而且这些HIV感染者并没有向自己的性伴侣说明自己的自身情况。当性行为变得在年轻人中非常寻常的时候,研究者就要考虑HIV的感染与传播的问题了。HIV的感染容易增加年轻人健康状况的复杂程度,并且对其自身以及性伴侣的健康都有极大的影响。

及时成功的干预行为有助于预防青春期年轻人感染HIV的高危行为。医生的早期干预会帮助这些年轻人及时作出安全的措施来保护HIV感染者伴侣不受HIV的感染。关键的一步就是告诉年轻人其HIV的感染状况。

这项研究中,18%的参与者在其发生性行为的时候并不知道自己已经感染了HIV。医生和家人必须告知年轻人自己HIV感染的情况和病情状况。研究者发现,有性行为的年轻人机体中HIV的病毒载量较高,大于5000拷贝/ml血液,而且81%的人群机体存在耐药性。这就无疑中增加了耐药性病毒在人群中的传播,以及限制了当前的疗法。研究者认为当前最关键的一步就是及时干预并且告知患病者的HIV感染情况,而且抗病毒疗法可以明显降低患者通过性行为传播HIV的可能性。

后期研究者希望能够开展更多的干预措施来降低青春期HIV感染者病毒的传播并且加强其意识和安全措施的使用。(生物谷Bioon.com)

Background. Factors associated with initiation of sexual activity among perinatally human immunodeficiency virus (HIV)–infected (PHIV+) youth, and the attendant potential for sexual transmission of antiretroviral (ARV) drug-resistant HIV, remain poorly understood. Methods. We conducted cross-sectional and longitudinal analyses of PHIV+ youth aged 10–18 years (mean, 13.5 years) enrolled in the US-based Pediatric HIV/AIDS Cohort Study between 2007 and 2009. Audio computer-assisted self-interviews (ACASI) were used to collect sexual behavior information. Results. Twenty-eight percent (95% confidence interval [CI], 23%–33%) (92/330) of PHIV+ youth reported sexual intercourse (SI) (median initiation age, 14 years). Sixty-two percent (57/92) of sexually active youth reported unprotected SI. Among youth who did not report history of SI at baseline, ARV nonadherence was associated with sexual initiation during follow-up (adjusted hazard ratio, 2.87; 95% CI, 1.32–6.25). Youth living with a relative other than their biological mother had higher odds of engaging in unprotected SI than those living with a nonrelative. Thirty-three percent of youth disclosed their HIV status to their first sexual partner. Thirty-nine of 92 (42%) sexually active youth had HIV RNA ≥5000 copies/mL after sexual initiation. Viral drug resistance testing, available for 37 of these 39 youth, identified resistance to nucleoside reverse transcriptase inhibitors in 62%, nonnucleoside reverse transcriptase inhibitors in 57%, protease inhibitors in 38%, and all 3 ARV classes in 22%. Conclusions. As PHIV+ youth become sexually active, many engage in behaviors that place their partners at risk for HIV infection, including infection with drug-resistant virus. Effective interventions to facilitate youth adherence, safe sex practices, and disclosure are urgently needed.
