Viral load in semen, vaginal fluid and rectal secretions - The effect of sexually transmitted infections on viral load

AbstractHerpes simplex viruses are evolutionarily ancient and ubiquitous. Correspondence to Professor Matthias Egger, Institute of Social and Preventive Medicine (ISPM), Finkenhubelweg 11, Bern, CH-3012, Switzerland. Frequent viral reactivation occurs within ganglia despite diverse and complementary host and viral mechanisms that predispose toward latency, suggesting that viral replication may be constantly occurring in a small minority of neurons at these sites. Of 122 patients, 30 (25%) had 32 infection episodes caused by RSV (5), PIV (17), MPV (6), influenza (3), RSV, or influenza (1). Correlations of STIs with rectal viral load were explored using multinomial regression modeling. At study enrollment, all had detectable PVL and 69% had detectable GT HIV-1 RNA. The link between STIs and people not on HAART has been proven since 1997, when a team of researchers found that men in Malawi with urethritis had a seminal viral load eight times higher than men without it.1 Similarly, in a study already referred to,2 Taylor and colleagues found that three of their nine ‘seminal super shedders’ had urethritis, one caused by chlamydia and two by NSU.

Validated for respiratory tract specimens only Other types of specimens which are not listed require consultation and approval by the MOC prior to testing The test is not intended for the screening of asymptomatic patients. Transmission was thought to be most common during an active outbreak; however, in the early 1980s, it was found that the virus can be shed from the skin in the absence of symptoms. Women in the treatment and observation groups had similar age (median, 42.5 years), race (of 30 women, 16 [53%] were white and 6 [20%] were black), and baseline plasma viral load distributions (27% detectable). The concentration of HIV-1-infected cells in semen varies substantially, ranging from 0.01% to 5% of white cells [8, 9]. Conclusion. Achieving a better understanding of how influenza is transmitted is an important public health goal [4]. Nine of the patients, four on treatment and five not, had asymptomatic STIs.

A randomized trial of HSV-2 suppression in Rakai, Uganda, showed a significant increase in HSV-2 shedding and genital ulcer disease after initiation of ART in a cohort of chronically HIV-infected women, possibly as part of immune reconstitution inflammatory syndrome (IRIS) [9, 11].
