The practice guideline on STD consultations from the Dutch College of General Practitioners sets out guidelines for the diagnosis and treatment of Chlamydia-infection, gonorrhoea, syphilis, trichomoniasis, genital herpes condylomata acuminata, hepatitis B, HIV-infection and pubic lice. Testing for Chlamydia-infection is always indicated if an STD is suspected but the necessity of also testing for gonorrhoea, syphilis, hepatitis B or HIV-infection depends on the likely risk. For the diagnosis of Chlamydia in a symptomatic woman it advises taking material from the cervix and urethra. In an asymptomatic woman Chlamydia infection is excluded by means of a urine test. In men a urethral swab of the first part of the urinary stream can be used for diagnosis. The first choice of treatment for gonorrhoea is a single 1 g intramuscular dose ofcefotaxime. The practice guidelines also examine other aspects of treatment for STDs including counselling and telling partners.

An accelerated course of hepatitis B vaccination was offered to men who had sex with men attending a genitourinary medicine clinic. The uptake and completion rates of the vaccine between 1 November 2002 and 28 February 2004 were compared with data for 1994. The uptake of vaccine was significantly higher during the former audit period than the latter (310 [98%] of 315 versus 146 [74%]). There was, however, no significant difference in completion rates between the two audit periods: 220 (73%) of the 302 men who initiated the accelerated schedule, compared with 118 (81%) of the 146 men who completed the standard course in 1994. Innovative means of ensuring completion of vaccination are needed.

An audit of outcomes from the first year of implementation of a super-accelerated hepatitis B vaccination schedule was performed. One hundred and sixteen patients commenced vaccination for hepatitis B in the study period. All notes were located and reviewed. In all, 72.4% of patients completed three vaccinations compared with 61.5% in an earlier period using the old schedule. Serological response for 39 patients was measured at approximately 12 weeks post commencement of vaccination. Of these 69.2% had mounted some serological response, 48.7% a good response. As expected, a faster vaccination schedule improves completion rates for the first three injections. Early serological responses are encouraging and comparable to published data for new schedule vaccination responses at 12 weeks. It is anticipated that serological response will continue to improve over the year before a booster dose of hepatitis vaccination is due.

The objective of this study was to describe the prevalence of sexually transmitted infections (STI), sociodemographic and behavioural characteristics in a population of male sex workers (MSW) in Antwerp, Belgium. Between September 1999 and March 2004, 129 MSW were reached by Gh@pro, an outreach programme providing preventive health care, free STI check-up and hepatitis B vaccination, to sex workers (SW). Sera were collected from 121 men, urine samples from 115 men and a questionnaire was filled in by 43 MSW. In 45.5% of MSW one or more STI were diagnosed (including hepatitis B), 76% on laboratory testing at first screening, 9% through symptomatology at first visit. The prevalence of HIV was 10.8%, hepatitis B virus (HBV) infection 28.9%, syphilis 12.5%, gonorrhoea 1.7% and Chlamydia trachomatis 9.7%. More than 50% of non-immune MSW completed their three-dose hepatitis B vaccination course. Prevalence of STI is concordant with published data on MSW; this population clearly requests and deserves particular attention and approach. There is an important difference in sociodemographic and behavioural characteristics between MSW working in the red light district and those working on the street. Health promotion should be tailored to the different subpopulations and outreach appears to be a successful tool.

The effect of HIV-related immunosuppression and antiretroviral therapy on the reactivation of latent hepatitis B virus (HBV) infection is unclear. We report four patients with advanced HIV-related immunosuppression and abnormal liver function tests who had evidence of HBV reactivation. Reclearance of hepatitis B occurred in two cases with HIV treatment regimens not containing lamivudine, suggesting that improved immune function may be responsible. In three cases, HBV reactivation was recognized during investigation for abnormal liver function initially attributed to drug toxicity. The possibility of HBV reactivation must be considered in the differential diagnosis of abnormal liver function in cases with advanced HIV.

The hepatitis B virus (HBV) X protein (HBx) is a multifunctional regulator of cellular signal transduction and transcription pathways and has a critical role in HBV replication. Much of the cytoplasmic signal transduction activity associated with HBx expression and its stimulation of viral replication is attributable to HBx-induced activation of calcium signaling pathways involving Pyk2 and Src tyrosine kinases. To further characterize upstream signal transduction pathways that are required for HBx activity, including activation of Src and mitogen-activated protein kinase (MAPK) cascades, we determined whether focal adhesion kinase (FAK), a known regulator of Src family kinases and the other member of the Pyk2/FAK kinase family, is activated by HBx. We report that HBx activates FAK and that FAK activation is important for multiple HBx functions. Dominant inhibiting forms of FAK blocked HBx activation of Src kinases and downstream signal transduction, HBx stimulation of NF-kappaB and AP-1-dependent transcription, and HBV DNA replication. We also demonstrate that HBx-induced activation of FAK is dependent on cellular calcium signaling, which is modulated by HBx. Moreover, prolonged expression of HBx increases both FAK activity and its level of expression. FAK activation may play a role in cellular transformation and cancer progression. HBx stimulation of FAK activity and abundance may also be relevant as a potential cofactor in HBV-associated hepatocellular carcinoma.

In Pakistan, male sex workers are predominantly transvestites and transsexuals known as Hijras. In 1998 in Karachi, Pakistan, we studied the seroprevalence of HIV, HBsAg and syphilis and associated risk factors in Hijras. Study subjects were verbally administered a structured questionnaire that determined risk behaviours for sexually transmitted and blood-borne diseases and knowledge of AIDS/STDs. After pre-test counselling, verbal consent was taken for serological testing. The results were provided on a one-on-one post-test counselling session. Three hundred male transvestites were approached; all agreed to answer the questionnaire, 208 consented to blood testing. Of 300, 81% acknowledged commercial sex with men. Of 208, prevalence of syphilis was 37%; HBsAg 3.4%; HIV 0%. The prevalence of HIV and hepatitis B virus (HBV) is low in transvestite sex workers but that of syphilis is high. Intervention programmes implemented at this stage can have an impact on HIV and STD prevention (Int J STD AIDS 1990;10:300-4).

To assess the potential for HIV acquisition among men who have sex with men (MSM) in Guangzhou, China, we conducted a cross-sectional, anonymous, face-to-face survey of MSM in the metropolitan area of Guangzhou, China. As a pilot recruitment for a cohort study, participants were recruited by convenience sampling through newspaper and television advertising, website information, and respondent referral. Blood samples were tested for HIV, hepatitis B (HBV), hepatitis C (HCV), and syphilis. Client-centered HIV and STD counseling was provided.A total of 201 MSM were interviewed and 200 blood samples were tested. The prevalence of HIV antibody was 0% (97.5% CI 0-1.8%); 17.5% of MSM were HBV surface antigen positive; 1.0% had HCV antibodies; 10.5% had antibodies to syphilis. Syphilis seropositivity was associated with sex with a foreign MSM in the last six months and 10.4% reported sex with a foreign MSM overall. The majority (54.7%) reported unprotected anal sex with other men. Nearly one-third (31.8%) had regular female partners; 25.9% were currently married to a woman; 6% had casual female partners; 4.5% had sex with a female sex worker; 4.5% had sex with a male sex worker; and 12.9% had unprotected vaginal sex and unprotected anal sex with a man in the past six months. Only one MSM reported injection drug use (0.5%). The currently low prevalence of HIV but high level of unprotected anal sex, high prevalence of syphilis infection, and sexual networks that include foreign MSM point to a transient window for HIV prevention among MSM in Guangzhou. We recognize challenges to recruiting a representative sample of MSM and retaining them in longitudinal cohort studies.

A cohort of 458 HIV-positive women under antiretroviral therapy has been followed at a reference hospital in Rio de Janeiro, Brazil. Most of them belong to impoverished social strata. Patients were screened for sexually transmitted infections (STIs) and gynaecologic conditions. Some STIs were found to be uncommon (e.g. chlamydial and gonococcal infections), while some conditions (bacterial vaginosis) and STIs, e.g. hepatitis B and human papilloma virus (HPV) infection, were found to be quite prevalent. The latter is of special concern, due to the high prevalence of HIV/HPV co-infection ( approximately 51%) and its association with severe immunodeficiency, in a context of unacceptable high levels of uterine cancer and uneven gynaecological care. HIV-positive women are in need of comprehensive health services, including high-quality, regular, gynaecologic care in order to diagnose and treat lower genital tract infections and prevent the evolution of HPV-related lesions. Reproductive counselling should be a part of this approach.

PTEN gene, a novel tumor suppressor is frequently mutated or deleted in several malignancies including human hepatocellular carcinoma (HCC). We report previously that human hepatitis B virus-X (HBx) protein achieves protection from apoptotic cell death through-PI3K-Akt-Bad signaling that is p53-independent in liver cells (JBC; 276, 16969 (2000)). In this report, we demonstrated the PTEN effect on HBx induced anti-apoptotic signaling in Chang liver cells (CHL). Expression of PTEN in CHL cells downregulate HBx induced PI3K, Akt activities, Akt, Bad phosphorylations, decreased caspase 3 activity and protection from DNA fragmentations. PTEN suppression of CHL cell growth at G1 phase (JBC;278,4057(2003)) in cell cycle analysis, which is overcome by HBx activated Akt/PKB further confirmed that same PI3K/Akt pathway is involved in cell survival and apoptosis by HBx and PTEN. PTEN suppression of HBx-mediated cell survival through PI3K pathway is specific, since PTEN does not suppress the effect of HBx on the protection from Fas-mediated apoptosis. Taken together, these findings demonstrate that PTEN potently modulate HBx-mediated signaling and is a viable target in therapeutic approaches to inhibit the formation of HCC caused by HBV infections.
