Classification of HIV virological failure using whole blood versus plasma viral load
Introduction: HIV viral load testing is the preferred monitoring approach for HIV infected patients on combination antiretroviral therapy (cART) as it is more sensitive than CD4 count and clinical monitoring. In resource limited settings, timely plasma separation and transportation to testing …

The impact of stressful life events on antiretroviral treatment adherence and viral load amongst adults in Gugulethu, Cape Town
Optimal antiretroviral treatment (ART) adherence is critical in achieving virologic suppression. Most people living with HIV (PLWH) experience HIV-related challenges which may be compounded by the experience of stressful life events (SLE) with adverse effects on their ART adherence and therefore …

Comparison of viral load values of Hybridcapture-II test between pre- and post- conization in patients with grade II/III cervical intraepithelial neoplasia
고등급 자궁경부 상피내종양의 원추절제술 전후의 인유두종바이러스 검사의 임상적 의의를 알아보고자 하였다. 아주대학교 병원에서 상피내종양으로 원추절제술을 받은 환자들 중 수술 전후에 인유두종바이러스 검사 (Hybrid capture-II)를 시행한 환자들을 대상으로 하여 임상양상과 재발 유무를 비교 분석하였다. 102명이 설정된 기준에 적합하였다. 이들 중 수술 시 절제 경계면의 종양침범 유무를 알 수 있는 경우는 64명이었다. 재발의 유무는 수술 후 인유두종바이러스 검사 결과 및 수술 시 경계면의 종양침범과 상관관계를 가지고 …
