| Abstract | A longitudinal study was conducted to evaluate the viral shedding present in cervicovaginal secretions of HIV-1-seropositive women receiving antiretroviral therapy. A total of 128 paired cervicovaginal and blood samples was obtained from 37 women during a median follow-up period of 21 months. A sensitive, competitive, polymerase chain reaction and a reverse transcription polymerase chain reaction were used for the simultaneous quantitation of HIV-1 proviral DNA and RNA in cervicovaginal cells and cell-free RNA in cervicovaginal secretions, as well as HIV-1 RNA in peripheral blood. The cumulative probability of detecting proviral DNA in genital secretions was significantly higher over time in women with detectable viremia than in women in whom HIV-1 RNA was persistently undetectable in plasma (<50 copies/ml) (P=0.028 by log-rank test). The presence and amount of proviral DNA, cell-associated RNA and cell-free RNA in the cervicovaginal secretions were positively correlated with the presence of detectable viremia or the number of HIV-1 RNA copies in plasma (Spearman rank correlation, 0.290, 0.279, and 0.305, respectively; all P<0.01), but no correlation was found with the CD4+ cell count. In addition, vaginal infections were positively correlated with the detection of proviral DNA in cervicovaginal secretions (odds ratio, 2.60; 95% confidence interval, 1.07–5.70). However, the positive correlation between the presence and amount of HIV in cervicovaginal secretions and the viral load in plasma provides no assurance that HIV shedding does not occur in the genital tract of women with undetectable HIV-RNA in plasma. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
