High HIV prevalence, low condom use and gender differences in sexual behaviour among patients with STD-related complaints at a Nairobi primary health care clinic

Of 22,274 patients > or = 12 years old attending a Nairobi primary health care (PHC) clinic, 1076 (4.8%) had STD-related complaints, of whom 980 underwent assessment of risk factors for human immunodeficiency virus (HIV) infection and infrequent condom use. Gonorrhoea, chancroid, syphilis seroactivity, trichomoniasis, or objective signs of STD were found in 78%, and HIV seropositivity in 15% of men and 19% of women. Most women were married, living with a spouse; while most men were single, or married, but living separated from a spouse. Among married men, last sex was with a female sex worker (FSW) or casual partner for 60% not living with a spouse and 26% living with a spouse (P<0.005). Two or more partners during the past year were reported by 82% of men and 25% of women (P <0.001), and 55% of men and 11% of women reported the last partner was high risk. HIV seropositivity among both genders was associated with numbers of partners, and among women, with being widowed or divorced. Only 3% reported use of a condom with the last partner. Among men whose last sex was with a FSW, 74% said the reason for not using a condom was not having one. Thus, infrequent condom use, low condom availability, and gender differences in behaviour necessitate modifying development policies that separate families; and better coordination between family planning, PHC, and AIDS/STD programmes, with improved supply, social marketing and community-based distribution of condoms in high-risk settings for STD/HIV prevention.     

An assessment of care provided by a public sector STD clinic in Cape Town

A study was undertaken in a Cape Town public sector STD clinic to evaluate the content and quality of care provided since it has been recognized that appropriate improvements in the management of conventional sexually transmitted diseases (STDs), including provision of correct therapy, health education, condom promotion and partner notification, could result in a reduced incidence of HIV infection. Our objectives were to assess patients' needs for health education and to assess the quality of STD management in terms of health education, condom promotion, partner notification, the validity of the clinical diagnoses and the adequacy of the treatments prescribed. The study subjects were sampled systematically, according to their gender. Patients included in the study were given a standardized interview and their clinical records reviewed. Specimens were collected for laboratory investigations. For each STD detected, the treatment was defined as adequate if drugs currently known to be active against that infection were prescribed. One hundred and seventy men and 161 women were included in the study (median age: females 22 years, males 26 years). While almost all patients believed their STD may have been caused by unprotected sexual intercourse, many also believed it may have been caused by other factors, such as bewitchment with traditional medicine. Only 21% of male and 37% of female patients received any education about STD transmission during the clinic visit, and only 25% of male and 36% of female patients received education about condom use. As a result of the low sensitivity of the clinicians' diagnoses, 16% of men and 61% of women left the clinic with at least one infection inadequately treated. The majority of patients were not receiving education for the prevention of STDs including HIV. Many were not receiving adequate treatment for their infections. The introduction of a syndromic management protocol in this setting would substantially reduce the proportion of inadequately-treated patients. However, syndromic protocols, and the means by which they are implemented, need to take into account problems with the clinical detection of genital ulcerative disease and candidiasis in women.     

Different expression of the alpha2-macroglobulin receptor/low-density lipoprotein receptor-related protein in human keratinocytes and fibroblasts

BACKGROUND AND OBJECTIVES: Although partner notification has been a long-standing intervention and prevention strategy for sexually transmitted diseases (STD), variations in partner notification practices across sites have never been documented. GOALS OF THE STUDY: To describe provider-assisted partner notification practices in four STD programs in the United States. STUDY DESIGN: Eleven disease intervention specialists (DIS) in each of three urban sites and seven DIS in one rural site documented their activities and clients for 14 working days using a personal digital assistant. RESULTS: Of 2,506 recorded activity hours across sites, 37.4% of the recorded time was spent on partner notification (PN) activities with 1148 clients. Field visits to locate contacts accounted for the largest proportion of time spent on PN. Overall, PN clients were cases of or were contacts to nonprimary and secondary (P&S) syphilis (39.6%), gonorrhea (25.5%), chlamydia (18.0%), HIV/AIDS (10.4%), and P&S syphilis (6.5%). CONCLUSION: The activities which constitute PN, the diseases for which PN is used, and the time spent on each PN client vary across sites. More research is needed on the determinants of these variations and their association with the ultimate goal of disease prevention.     

Sexual behaviour among London GUM clinic attenders: implications for HIV education

The aim of this study was to describe the sexual behaviour of a sample of genitourinary medicine (GUM) clinic attenders, 5 years after the launch of the UK government HIV media campaigns. A gender-specific and anonymous cross-sectional self-completion questionnaire was modified from the National Survey of Sexual Attitudes and Lifestyle and completed by 250 men and 250 women. The majority of the respondents were in their twenties, lived in London and were employed or students. Sixty-eight per cent of the men reported that one or more of their last 3 partners was not a regular partner. For those men whose last sexual encounter was with a new partner, 27% of heterosexuals and 33% of homosexuals reported using a condom. Fifty-one per cent of women reported one or more non-regular partners among their last 3 partners. For those women whose last sexual encounter was with a new partner, 43% of heterosexuals and 75% of bisexuals used a condom. Seventy-eight per cent of men and 75% of women had had a previous sexually transmitted disease (STD). These findings highlight the persistence of practices associated with the risk of contracting or transmitting HIV infection and which needs to be addressed in future educational campaigns. The GUM clinic population is an important population to monitor over time, either by longitudinal or serial cross-sectional studies. The results of this study provide a baseline against which to gauge the effects of future educational interventions.     

Risk factors for urethritis in heterosexual men. The role of fellatio and other sexual practices

BACKGROUND: Nonchlamydial nongonococcal urethritis (NGU) is a common sexually transmitted disease (STD) in heterosexual men. Prior studies have suggested that NGU may be acquired by insertive oral sex. GOAL: To assess the association of oral sex and other sexual practices with nonchlamydial NGU in heterosexual men in order to better understand this syndrome and to guide its prevention and treatment. Risk factors for urethral gonorrhea and chlamydial infection were explored to contrast with NGU. STUDY DESIGN: A retrospective case-control study was conducted among heterosexual men attending as STD clinic during 1993 and 1994. The study included 4,848 men who were sexually active within the prior 2 months and had urethral specimens obtained for Gram's stain, culture for Neisseria gonorrhoeae, and culture for Chlamydia trachomatis. RESULTS: Insertive oral sex was not shown to be an independent risk factor for NGU. Independent predictors of nonchlamydial NGU by multivariate analysis included African-American race (odds ratio [OR] 3.71, 95% confidence interval [95% CI] 3.06 to 4.50) and having > or = two sex partners in the prior 2 months (OR 1.45, 95% CI 1.20 to 1.75). History of using condoms "always" was negatively associated with NGU (OR 0.59, 95% CI 0.43 to 0.79), gonorrhea (OR 0.31, 95% CI 0.17 to 0.56), and chlamydial infection (OR 0.67, 95% CI 0.44 to 1.03). CONCLUSIONS: This study supports the sexually transmitted nature of nonchlamydial NGU but did not confirm an association with oral sex. However, the analysis was compromised by the rarity of insertive oral sex as patients' only sexual exposure. Consistent condom use protects against all causes of sexually acquired urethritis.     

Mechanical alterations in smooth muscle from mice lacking desmin

The authors conducted formative research on the use of partner notification with HIV-infected drug users (i.e. those who use/abuse injectable drugs, crack or cocaine) in order to guide the development of an effective intervention for this population in New York City. Structured focus group and personal interviews were conducted with 25 in- and out-of-treatment drug users, 23 counsellors from a sexually transmitted disease (STD) clinic and a methadone maintenance treatment programme (MMTP), and nine experts in the field of HIV partner notification and/or substance abuse prevention and treatment. Results revealed factors associated with HIV-positive disclosure, the strengths and barriers of existing partner notification programmes and issues that should be considered in designing an effective intervention with HIV-infected drug users. Further research and planning activities are recommended before piloting and evaluating such a programme.     

Improving quality of sexually transmitted disease case management in rural South Africa

OBJECTIVE: To measure quality of sexually transmitted disease (STD) syndromic case management and aspects of health-seeking behaviour at baseline in an intervention trial. SETTING: Ten rural primary care clinics, Hlabisa district, South Africa. DESIGN: Simulated patients (fieldworkers trained to present with STD syndromes) made a total of 44 clinic visits; 49 STD patients were interviewed when exiting clinics; facilities were assessed for availability of necessary equipment and drugs; 10 focus group discussions were held with staff; and STD syndrome surveillance was performed in all 10 clinics. RESULTS: A total of 9% of simulated patients were correctly managed (given correct drugs, plus condoms and partner notification cards), recommended drug treatment was given in only 41% of visits, and appropriate counselling was given in 48% of visits. Among patients leaving the clinic, although 39% waited over an hour to be seen and only 37% were consulted in private, all reported staff attitudes as satisfactory or good. Only six clinics had syndromic management protocols available, three reported intermittent drug shortages, and seven lacked partner notification cards. Focus group discussions revealed good staff knowledge about STD, but showed lack of training in syndromic management and low morale. Surveillance data showed that while 75% of those presenting for care did so within 1 week of symptom onset, 27% had been treated for an STD in the preceding 3 months, and only 6% of those treated were contacts. CONCLUSIONS: Quality of STD case management was poor despite good staff knowledge and availability of most essential resources. An intervention comprising staff training and STD syndrome packets has been designed to improve quality of case management.     

Detection of Chlamydia trachomatis infection by PCR in first voided urines in men

The goal of this study was to evaluate whether the new commercially available PCR-based assay Amplicor C. trachomatis (Roche Molecular Systems) could improve the diagnosis of chlamydial urogenital infections in men, compared with cell culture of C. trachomatis considered as the reference method. A total of 466 men attending the STD clinic were tested by the Amplicor test in urine and by cell culture in urethra. The prevalence of C. trachomatis was 13.7% (64/466) by cell culture and 14.4% (67/466) by the Amplicor test. After resolution of the discrepant results, the sensitivity of culture was 91.4% in male urethral specimens. The resolved sensitivity of the PCR assay was 92.7% in male urine and the specificity was 99.5%. We concluded that this rapid PCR-based assay showed an improvement in quality for diagnosing C. trachomatis infections in men.     

The spread of HIV in Greenland. Heterosexual epidemic--risk or reality? A 10-year review of HIV transmission and preventive care

With the first report of an HIV-positive Inuit in 1985 Greenland was considered a high risk area for a self-sustained heterosexual HIV-epidemic, due to high incidences of sexually transmitted diseases. In 1986 a national HIV-intervention programme began with two major aims: Firstly, improved STD treatment and incitation to change of sexual high-risk behaviour, secondly, close monitoring of HIV-antibody test activity, partner notification and repeated surveys of knowledge and sexual behaviour in selected populations. Very early the spread of HIV in Greenland became heterosexually transmitted and self-sustained, with repeated local small-scale epidemics in a subpopulation characterized by frequent STD's, alcoholism, lack of education and vulnerable social and economic resources. From 1994 to 1997 a marked increase in new cases was reported, and in November 1997 the total number was 76 HIV-positives in the Greenlandic population of 50,000 Inuits. The successful defeat of STD's, such as gonorrhoea and syphilis has not been followed by a change in sexual behaviour among the youth in Greenland. High incidences of genital chlamydial infections, early sexual debut and high frequencies of excessive promiscuity render Greenland an alarming potential for a future HIV-epidemic. This threat calls for an intensified national prevention programme, with close monitoring of the known HIV-positives and the potentially infected persons in the population at risk, and new campaigns to reduce high-risk sexual behaviour among the youth.     

Gender differences in risk behaviors among HIV+ persons with an IDU history. The link between partner characteristics and women's higher drug-sex risks. The Manif 2000 Study Group

BACKGROUND AND OBJECTIVES: Risk-taking behaviors differ among women and men injection drug users (IDU). GOAL: To specify the nature of sexual and drug risk-taking among women IDU and ex-IDU and how it relates to partner characteristics. DESIGN: A cross-sectional analysis of 324 HIV+ subjects enrolled into a prospective cohort study in Marseille, France. RESULTS: Women, as compared with men, were considerably more likely to report nonuse of condoms with a main partner (31% versus 12%). They were more likely to shoot with a partner at last injection (39% versus 12%), but far less likely to sterilize used needles (4% versus 16%). Two thirds of both men and women reported consistent condom use with a seronegative partner, but only 47% of men and 23% of women reported the same with a seropositive partner. Among the women only, needle and syringe sharing was associated with consistent use of a condom. CONCLUSIONS: Women reported behaviors which protect their partners from STD infection more frequently than behaviors which protect themselves. Greater attention must be paid to sexual risk-taking among HIV+ women.     

IgE, IgA, and IgG responses to common yeasts in atopic patients

To assess the incidence of HIV infection and risk factors associated with HIV seroconversion among patients attending clinics for sexually transmitted diseases (STD), medical record reviews were conducted in 12 clinics in 7 U.S. cities. The records of all patients who initially tested negative for HIV from 1991 through 1996 and who received at least one additional HIV test during the study period were reviewed. In each of 7 cities, 5 to 112 patients seroconverted. Of the 286 seroconverters identified in total, 53% (152 of 286) were heterosexual men and 28% (81 of 286) were women. HIV incidence rates among men who have sex with men (MSM) ranged by city from 0.81 to 7.0 new infections/100 person-years. Rates among heterosexual men and women ranged from 0.018 to 1.2 infections/100 person-years. Multivariate analyses showed that drug use was associated with HIV seroconversion only among heterosexuals. Most new HIV infections in these clinics are being transmitted heterosexually and are associated with drug use. Nevertheless, MSM, particularly young MSM, are at greatest risk for HIV in this population: 1 of 47 seroconvert/year. The effective use of targeted prevention efforts depends upon the continued ability to monitor the incidence of HIV infection.     

Morning-to-evening change in refraction, corneal curvature, and visual acuity 11 years after radial keratotomy in the prospective evaluation of radial keratotomy study. The PERK Study Group

One-hundred thirteen men (mean age, 23 years) who presented with inguinal buboes to a government-operated hospital for sexually transmitted diseases (STDs) in Bangkok were studied between February 1987 and February 1989. The median duration of preceding symptoms was 7 days (range, 1-62 days). The majority of patients (74; 65%) had received treatment previously; 31 (27%) were febrile, 13 (12%) had extrainguinal lymphadenopathy, and 31 (27%) had concurrent active genital ulcers. There was no history of genital ulceration in 66 (58%) of the patients. Pus was obtained from 51 of the 110 buboes aspirated for culture; 21 (41%) of these cultures yielded Haemophilus ducreyi, and 2 (3.9%) were positive for Chlamydia trachomatis on immunofluorescence microscopy. Saline (1 mL) was injected and reaspirated from the buboes of 35 of the other 59 patients; 3 buboes yielded H. ducreyi and 9 were positive for C. trachomatis. All cultures for other aerobic and anaerobic bacteria and viruses in intact buboes were negative. Syphilis serology was positive in only one case. Patients attending STD clinics in this region who have large, fluctuant, edematous inguinal buboes containing pus should receive presumptive treatment for chancroid. If there is no pus, then the bubo is more likely to be caused by lymphogranuloma venereum.     

Prevalence and risk factors for hepatitis B virus infections among visitors to an STD clinic

OBJECTIVE: To determine the prevalence and risk factors for hepatitis B virus (HBV) infections among individuals attending an STD clinic in a low endemic region. STUDY DESIGN: A total of 1228 women and 1648 men attending the STD clinic at the University Hospital Rotterdam, Netherlands, were examined for HBV infection by determination of hepatitis B surface antigen (HBsAg) and antibodies to hepatitis B core antigen (anti-HBc). Demographic characteristics, information on sexual behaviour, and intravenous drug use were recorded. RESULTS: The seroprevalence of HBsAg was 1.4% in women and 2.1% in men (0% in homosexual men). The seroprevalence of anti-HBc was 13% in women and 20% in men (36% in homosexual men). Native country, intravenous drug use, a history of STD, and the number of partners in the past half year (inversely) were independent risk factors for HBsAg positivity in women and heterosexual men. For anti-HBc independent associations were observed for native country, age, intravenous drug use, commercial sex, number of lifetime partners, homosexual contacts, orogenital contact (inverse), and a history of STD. CONCLUSION: The HBV prevalence in the STD clinic attendants was high, exceeding the national estimate, and indicates that the STD clinic population may be considered a high risk group. Our data confirmed an increased risk for HBV infections among established risk groups. Therefore, these risk groups should be routinely screened to identify HBV cases for counselling and contact tracing.     

HIV and other sexually transmitted diseases at a rural hospital in Zimbabwe

OBJECTIVE: To define the epidemiological characteristics of STD patients attending an outpatient clinic in rural Zimbabwe, to examine the aetiologic agents causing infection and to determine their relationship with HIV infection. SUBJECTS: 319 men and 146 women, making a sample of about 7% all patients attending an STD clinic during the 3 month study period. Microbiological data were collected from 104 men and 72 women selected randomly from these. Pregnant women were excluded and patients who had received antibiotics within the previous 14 days were excluded from the microbiology sub-sample. SETTING: An outpatient STD clinic at a District Hospital on a major truck route about 300 km north of the capital, Harare. METHODS: All new patients attending the clinic during a 3 month period were enrolled for clinical and epidemiological investigations using a standard procedure. Specimens for microbiological investigation were taken from every second patient seen on the first three days of each week. RESULTS: The typical patient was male (m:f ratio 2.2) aged 20-29 years (68% patients), not married (56% men) and in paid employment (66% men vs. 27% for the district). In men the most common presenting feature was genital ulceration, while in women, discharges were more common. Genital warts were noted frequently in both sexes. In the sub-sample examined microbiologically, H ducreyi was isolated from 46% ulcers clinically diagnosed as chancroid, and motile spirochaetes were detected in 25% painless ulcers. Neither of these were detected in ulcers in women, but HSV antigen was found as frequently in ulcers from men (19%) as from women (17%). In patients with genital discharges, gonococcal infection occurred in 64% men and 17% women, while T vaginalis was isolated from 39% women and only 8% men. Over 60% gonococcal isolates were PPNG, and 18% showed in vitro resistance to tetracycline. Yeasts, mainly C albicans were isolated from 42% women with a discharge and 25% women with ulcers. In men the presence of yeasts was associated with superficial ulceration and itchiness of the glans. Positive HIV-1 serology was found in 64% patients. There was no statistical association with current genital ulcers, though there was an association with previous STD episodes and particularly with serological evidence of syphilis. Apart from yeasts, there was no association between positive HIV-1 serology and the presence of pathogens in the genital tract. CONCLUSIONS: The high prevalence of HIV-1 antibodies in STD patients in Karoi suggests integration of STD and AIDS control programmes to be a necessity. Since paid employment was a common feature of both STD clinic attendance and HIV-1 seropositivity, these programmes may be effectively directed through the work place.     

A graduating medical school class evaluates their educational experience

CONTEXT: Comparatively little is known about how U.S. adult men's attitudes and characteristics influence their decision to use contraceptives to prevent pregnancy and to take actions to protect themselves from infection with sexually transmitted diseases (STDs). METHODS: Attitudinal and background data on 1,595 men from the 1991 and 1993 waves of the National Survey of Men (NSM) were used, through logistic regression techniques, to predict the likelihood of current contraceptive use to prevent pregnancy and recent efforts to avoid STD infection among men in three types of sexual relationship--marriage, cohabitation and dating. RESULTS: At the 1993 interview, 58% of men were using contraceptives to prevent pregnancy and 22% had recently taken actions to protect themselves from STDs. Men's concern about how easy a method was to use reduced the likelihood of STD protection, but had no influence on contraceptive use to prevent pregnancy; however, concerns about a method's risks to the female partner increased the likelihood of both outcomes. Couples in which the man expected his partner to take primary responsibility for contraception were 40% as likely to be protecting themselves against STDs as were couples in which the man believed he shared or had greater responsibility. Married men were the least likely to be protecting themselves against STDs, whereas men who were dating were the most likely to do so. CONCLUSIONS: Men's attitudes and characteristics were important predictors of contraceptive use to prevent pregnancy and of efforts to protect against STDs, even after controls for the female partner's characteristics were entered in the analysis. The findings emphasize the need to include men in interventions aimed at reducing unintended pregnancy and STD transmission.     

Spread of HIV infection in married monogamous women in India

CONTEXT: A high prevalence of human immunodeficiency virus (HIV) infection in female sex workers (FSWs) and men who attend sexually transmitted disease (STD) clinics poses a risk for spread of infection to other populations. OBJECTIVE: To examine spread of HIV to a low-risk population by comparing prevalence of, and risk factors for, HIV and STDs in FSWs and non-FSWs. METHODS: Women attending STD clinics in Pune, India, were assessed for STDs and HIV from May 13, 1993, to July 11, 1996. Demographic and behavioral information was collected, and clinical and laboratory assessment was performed. MAIN OUTCOME MEASURE: Prevalence and risk determinants of HIV infection. RESULTS: Of 916 women enrolled, 525 were FSWs and 391 were non-FSWs. Prevalence of HIV in FSWs and non-FSWs was 49.9% and 13.6%, respectively (P<.001). In multivariate analysis, inconsistent condom use and genital ulcer disease or genital warts were associated with prevalent HIV in FSWs. History of sexual contact with a partner with an STD was associated with HIV in non-FSWs. CONCLUSIONS: Infection with HIV is increasing in non-FSWs, previously thought to be at low risk in India. Since history of sexual contact with their only sex partner was the only risk factor significantly associated with HIV infection, it is likely that these women are being infected by their spouses. This underscores the need for strengthening partner-notification strategies and counseling facilities in India.     

Sexually transmitted diseases: United States, 1995

Over the past two decades, the United States has experienced some dramatic changes in the rates of three "classic" sexually transmitted diseases (STDs) as well as the introduction of a variety of newer and more complex STD organisms. Rates of primary and secondary syphilis increased through the mid-1980s to a record high of 20.3 cases per 100,000 population in 1990. Since then, rates have dropped 69 percent to 6.3, the lowest rate in 35 years. Gonorrhea rates increased steadily between 1950 and 1975, plateaued between 1975 and 1978, before beginning a gradual but quite steady decline. In 1995 the rate of gonorrhea reached a 30-year low of 149.5 per 100,000. Rates of chlamydial infections, however, have increased more than 55 since 1984 as screening programs proliferated and reporting improved. These infections are commonly found in sexually active adolescents and young adults, and for every case detected in men, there are approximately six detected in women. Rates of syphilis (primary and secondary) and gonorrhea are concentrated primarily in southern states, while chlamydial infections appear to be more widespread geographically. Despite the availability of diagnostic tests and effective treatment regimens for many infectious diseases, STDs continue to target certain populations. They disproportionately affect the poor, inner-city residents and minority groups. The consequences of the diseases are many and varied, and risk of sterility, ectopic pregnancy, fetal death and/or blindness are markedly increased among women with STDs. In addition, risk of HIV infection appears to be increased among persons with a history of having an STD.     

Low frequency of BRCA1 germline mutations in 45 German breast/ovarian cancer families

Serum samples from 47 men with current condylomas, 32 men with a history of condylomas and from 205 men with no history of genital wart disease, who were attending sexually transmitted disease (STD) clinics at two different hospitals in Stockholm, were analyzed for the presence of immunoglobulin G (IgG) and A (IgA) antibodies to capsids of human papillomavirus types 6 and 11. IgG to HPV type 6 was found among 35% of patients with a history of condylomas compared to 10% of controls (p = 0.0003), but only among 27% of patients with current condylomas. Antibodies to HPV 6 and to HPV 11 showed a very limited correlation, suggesting that the antibodies are HPV-type restricted. The results strengthen conclusions from a previous serological study indicating that IgG antibodies against HPV 6 develop late during condylomatous disease and mostly reflect previous exposure to the virus.
