Point-of-care testing for sexually transmitted infections in low-resource settings.

BACKGROUND: Both the global incidence and the prevalence of sexually transmitted infections (STIs) continue to increase, affecting hundreds of millions of individuals, particularly in low-to middle-income countries. Although a definitive diagnosis is desirable to inform STI treatment, syndromic management is the most widely used strategy in resource-limited settings. With the development of point-of-care (POC) tests, it is important to discuss how laboratories will need to adapt to new training and supervisory roles in support of testing, which will largely be performed by peripheral clinical staff. OBJECTIVES: To discuss potential applications of STI POC tests, how they could improve existing STI control strategies and the role of clinical and reference laboratories in support of initiatives to improve STI management and control activities. SOURCES: Narrative literature review and expert opinion. CONTENT: The paper outlines the current status of the STI epidemic worldwide and discusses the problems associated with current approaches to control these infections, particularly in low-resource settings. The roles of clinical and reference laboratories will need to change to provide support for POC and near-patient STI testing as these technologies are introduced into clinical as well as laboratory settings. IMPLICATIONS: Laboratories will be expected to play a leading role in the introduction and implementation of POC and near-patient STI testing. They will be required to facilitate training and provide technical and supervisory support to clinical staff on the use of these technologies to augment existing STI management and surveillance programmes. In order to provide quality service, they will need to develop, introduce and maintain sustainable local quality control and external quality assurance systems. Evidence from implementation research for introduction and scale up of STI POC tests in different STI epidemic and laboratory infrastructure settings is required.

[The comparative characteristic of approaches to monitoring and evaluation of morbidity of psoriasis in the Russian Federation and the countries of the European region].

The psoriasis is chronic inflammatory dermatitis that is accompanied by severe damage of skin and musculoskeletal system and affects functions of other organs and systems. The epidemiological data concerning prevalence and morbidity of psoriasis all over the world varies significantly. The article presents comparative characteristic of approaches to monitoring and evaluation of psoriasis morbidity in the Russian Federation and in the countries of the European region. The differences were revealed such as absence both of indices to evaluate quality of life of patients with psoriasis and specific population epidemiological studies in national system of monitoring and evaluation of the Russian Federation.

Factors related to condomless anal intercourse between men who have sex with men: results from a European bio-behavioural survey.

BACKGROUND: Relationship status is an important factor associated with condomless anal intercourse (CAI) amongst men who have sex with men (MSM). METHODS: A multi-centre bio-behavioural survey with MSM was conducted in 13 European cities (n = 4901) exploring factors associated with CAI via bivariate and multivariate multilevel logistic regression analyses. RESULTS: Likelihood of CAI with casual partners was associated with being 'out' to a majority (AOR = 1.19;95% CI 1,1.42); knowing their HIV status (AOR = 1.86; 95% CI 1.25,2.76); using substances (1-2 AOR = 1.39; 95% CI 1.16,1.63, 2+ AOR = 1.81; 95% CI 1.35,2.42); being older (AOR = 0.98; 95% CI 0.97,0.99); successful sero-communication (AOR = 0.79; 95% CI 0.67,0.94); and, not having a recent HIV test (AOR = 0.78; 95% CI 0.66,0.92). CAI with steady partners was associated with successful sero-communication (AOR = 2.72; 95% CI 2.72,3.66); not having a recent HIV test (AOR = 1.26; 95% CI 1.09,1.46), and; being older (AOR = 0.99; 95% CI 0.98,0.99). CONCLUSIONS: Understandings of partner type and/or relationship status in relation to CAI amongst MSM can potentially play an important role in the development of culturally appropriate HIV/STI prevention and risk-reduction efforts targeting at-risk MSM. Our results speak to the need to consider segmented and tailored public health and health promotion initiatives for MSM with differing CAI behaviours and relationship profiles.

Brief sexuality communication--a behavioural intervention to advance sexually transmitted infection/HIV prevention: a systematic review.

BACKGROUND: Throughout the last decade substantial research has been undertaken to develop evidence-based behaviour change interventions for sexual health promotion. Primary care could provide an opportunistic entry for brief sexual health communication. OBJECTIVES: We conducted a systematic review to explore opportunistic sexual and reproductive health services for sexual health communication delivered at primary health care level. SEARCH STRATEGY: We searched for studies on PubMed, ProQuest, CINAHL, Jstor, Scopus/Science Direct, Cochrane database of systematic reviews, EBSCO, CINAHL, PsychoInfo, and Web of Knowledge. Both published and unpublished articles were reviewed. SELECTION CRITERIA: All randomised controlled trials and controlled clinical trials were included. Participants of all ages, from adolescence onwards were included. Brief (10-60 minutes) interventions including some aspect of communication on sexual health issues were included. DATA COLLECTION AND ANALYSIS: Data were extracted by two reviewers independently using a standardised form. Interventions differed from each other, hence meta-analysis was not performed, and results are presented individually. MAIN RESULTS: A total of 247 articles were selected for full-text evaluation, 31 of which were included. Sexually transmitted infections (STIs)/HIV were less often reported in the intervention group compared with the control group. Condom use was higher in most studies in the intervention group. Numbers of sexual partners and unprotected sexual intercourse were lower in the intervention groups. CONCLUSIONS: There is evidence that brief counselling interventions have some effect in the reduction and prevention of STIs/HIV. Some questions could not be answered, such as the effect over time and in different settings and population groups.

HIV bio-behavioural survey among men who have sex with men in Barcelona, Bratislava, Bucharest, Ljubljana, Prague and Verona, 2008-2009.

Data from 23 European countries show that the annual number of HIV diagnoses in men who have sex with men (MSM) increased by 86% between 2000 and 2006. This paper reports the main preliminary results of a bio-behavioural survey in MSM with a specific focus on HIV prevalence and use of United Nations General Assembly Special Session (UNGASS) indicators in six cities in Southern and Eastern Europe. Time-location sampling (TLS) was used. A total number of 2,356 questionnaires and 2,241 oral fluid samples were collected (invalid samples 4.1%). The data show different socio-demographic patterns across countries regarding age, level of education, living conditions, living area and self-identity. Southern European cities had the highest percentage of people who had tested for HIV and collected the result. More than 50% of respondents in the sample from Barcelona reported having used a condom last time they had anal sex (57.2%), whilst in all other cities this proportion was below 50%. The cities with the highest HIV prevalence in MSM were Barcelona (17.0%) and Verona (11.8%) whilst lower percentages were reported in Bratislava (6.1%), Bucharest (4.6%), Ljubljana (5.1%) and Prague (2.6%). The low prevalence in Eastern European cities is encouraging. However, with the level of high-risk sexual behaviour documented and the lower frequency of HIV test seeking behaviour, there is a clear risk of an increase in HIV transmission.
