Diagnosis of sexually transmitted infections in developing nations using syndromic management: Is it working?

Sexually transmitted infections (STIs) are a major public health problem, and controlling their spread is a priority. According to the World Health Organization (WHO), there are 340 million new cases of treatable STIs among 15–49 year olds that occur yearly around the world (1). Infection with STIs can lead to several complications such as pelvic inflammatory disorder (PID), cervical cancer, infertility, ectopic pregnancy, and even death (1). Additionally, STIs and associated complications are among the top disease types for which healthcare is sought in developing nations (1), and according to the UNAIDS report, there is a strong connection between STIs and the sexual spread of HIV infection (2). In fact, it is estimated that the presence of an untreated STI can increase the likelihood of contracting and spreading HIV by a factor up to 10 (2). In addition, developing countries are poorer in resources and lack inexpensive and precise diagnostic laboratory tests for STIs, thereby exacerbating the problem. Thus, the WHO recommends syndromic management of STIs for delivering care where lab testing is scarce or unattainable (1). This approach utilizes the use of an easy to use algorithm to help healthcare workers recognize symptoms/signs so as to provide treatment for the likely cause of the syndrome. Furthermore, according to the WHO, syndromic management offers instant and legitimate treatment compared to clinical diagnosis, and that it is also more cost-effective for some syndromes over the use of laboratory testing (1). In addition, even though it has been shown that the vaginal discharge syndrome has low specificity for gonorrhea and Chlamydia and can lead to over treatment (1), this is the recommended way to manage STIs in developing nations. Thus, the purpose of this paper is to specifically address the following questions: is syndromic management working to lower the STI burden in developing nations? How effective is it, and should it still be recommended? To answer these questions, a systematic literature review was conducted to evaluate the current effectiveness of syndromic management in developing nations. This review examined published articles over the past 5 years that compared syndromic management to laboratory testing and had published sensitivity, specificity, and positive predicative value data. Focusing mainly on vaginal discharge, urethral discharge, and genital ulcer algorithms, it was seen that though syndromic management is more effective in diagnosing and treating urethral and genial ulcer syndromes in men, there still remains an urgent need to revise the WHO recommendations for managing STIs in developing nations. Current studies have continued to show decreased specificity, sensitivity and positive predicative values for the vaginal discharge syndrome, and high rates of asymptomatic infections and healthcare workers neglecting to follow guidelines limit the usefulness of syndromic management. Furthermore, though advocate d as cost-effective by the WHO, there is a cost incurred from treating uninfected people. Instead of improving this system, it is recommended that better and less expensive point of care and the development of rapid test diagnosis kits be the focus and method of diagnosis and treatment in developing nations for STI management. ^

The determinants of sexually transmitted infection screening uptake among African American young adults: A systematic review

Objective. To conduct a systematic review of literature to determine the factors associated with STI including HIV screening uptake among African American young adults in the United States. ^ Methods. The electronic databases OVID Medline and OVID PsycINFO were systematically searched to identify potentially relevant articles. Ninety-six articles were initially identified, five of which were included in the final review. ^ Results. The results of this review were inconclusive. There was no definitive evidence to suggest which determinants were predictive of screening uptake. ^ Conclusions. There is a limited body of literature examining the demographic and behavioral risk factors associated with uptake or non-uptake of STI including HIV screening among African American young adult populations. This finding points to the need for more quality research to be conducted in this area. ^

Sexually transmissible diseases, sexual factors and prostate cancer: A review of literature

A review of literature was carried out regarding sexually related factors, sexually transmissible diseases (STD's) and infections with prostate cancer (PC) development risk. The review of literature, in conjunction with the tabulation of studies, suggested that ejaculation and circumcision may play a protective role in the development of PC and that multiple sex partners and an active sex life may play a causal role in the development of PC which may negate and counteract the protective effects of ejaculation and circumcision. HIV infection may plausibly play a function in deteriorating and compromising immune controls on carcinogenesis. Because of the coexistence of a highly active sexual lifestyle and sexual promiscuity with the growing occurence of STD's, their maybe a correlation with the high incidence of prostate cancer in the United States. Potential multi-institutional studies are warranted to confirm the high incidence of this neoplasm with the increasing cases of STD's and if in fact there is a proportional association to further elucidate the factors responsible for its high incidence.^

A distinctive clade B HIV type 1 is heterosexually transmitted in Trinidad and Tobago

HIV-1 transmission worldwide is predominantly associated with heterosexual activity, and non-clade B viruses account for the most spread. The HIV-1 epidemic in Trinidad/Tobago and the Caribbean shares many features with such heterosexual epidemics, including a prominent role for coincident sexually transmitted diseases. This study evaluates the molecular epidemiology of HIV-1 in Trinidad/Tobago during a period when abrupt transition from homosexual to heterosexual transmission occurred in the absence of injecting drug use, concomitant with a rapid rise in HIV-1 prevalence in the heterosexual population. Of 31 viral isolates studied during 1987–1995, all cluster with subtype B reference strains. In the analysis of full env genes from 22 early seroconverters, the Trinidad isolates constitute a significant subcluster within the B subtype. The Trinidad V3 consensus sequence differs by a single amino acid from the prototype B V3 consensus and demonstrates stability over the decade of this study. In the majority of isolates, the V3 loop of env contains a signature threonine deletion that marks the lineage of the Trinidad HIV-1 clade B epidemic from pre-1984. No phenotypic features, including syncitium induction, neutralization profiles, and chemokine receptor usage, distinguish this virus population from other subtype B viruses. Thus, although the subtype B HIV-1 viruses being transmitted in Trinidad are genetically distinguishable from other subtype B viruses, this is probably the result of a strong founder effect in a geographically circumscribed population rather than genetic selection for heterosexual transmission. These results demonstrate that canonical clade B HIV-1 can generate a typical heterosexual epidemic.
