Operational performance of an STD control programme in Mwanza Region, Tanzania.

OBJECTIVES: To describe important details of the design and operational features of the Mwanza sexually transmitted diseases (STD) control programme. To assess the feasibility of the intervention, the distribution of STD syndromes observed, the clinical effectiveness of syndromic STD case management, the utilisation of STD services by the population, and the quality of syndromic STD services delivered at rural health units. METHODS: The intervention was integrated into rural primary healthcare (PHC) units. It comprised improved STD case management using the syndromic approach, facilitated by a regional programme office which ensured the training of health workers, a reliable supply of effective drugs, and regular support supervision. Five studies were performed to evaluate operational performance: (i) a survey of register books to collect data on patients presenting with STDs and reproductive tract infections (RTIs) to rural health units with improved STD services, (ii) a survey of register books from health units in communities without improved services, (iii) a survey of register books from referral clinics, (iv) a home based cross sectional study of STD patients who did not return to the intervention health units for follow up, (v) a cross sectional survey of reported STD treatment seeking behaviour in a random cohort of 8845 adults served by rural health units. RESULTS: During the 2 years of the Mwanza trial, 12,895 STD syndromes were treated at the 25 intervention health units. The most common syndromes were urethral discharge (67%) and genital ulcers (26%) in men and vaginal discharge (50%), lower abdominal tenderness (33%), and genital ulcers (13%) in women. Clinical treatment effectiveness was high in patients from whom complete follow up data were available, reaching between 81% and 98% after first line treatment and 97%-99% after first, second, and third line treatment. Only 26% of patients referred to higher levels of health care had presented to their referral institutions. During the trial period, data from the cohort showed that 12.8% of men and 8.6% of women in the intervention communities experienced at least one STD syndrome. Based on various approaches, utilisation of the improved health units by symptomatic STD patients in these communities was estimated at between 50% and 75%. During the first 6 months of intervention attendance at intervention units increased by 53%. Thereafter, the average attendance rate was about 25% higher than in comparison communities. Home visits to 367 non-returners revealed that 89% had been free of symptoms after treatment, but 28% became symptomatic again within 3 months of treatment. 100% of these patients reported that they had received treatment, but only 74% had been examined, only 57% had been given health education, and only 30% were offered condoms. Patients did not fully recall which treatment they had been given, but possibly only 63% had been treated exactly according to guidelines. CONCLUSIONS: This study demonstrated that it is feasible to integrate effective STD services into the existing PHC structure of a developing country. Improved services attract more patients, but additional educational efforts are needed to further improve treatment seeking behaviour. Furthermore, clear treatment guidelines, a reliable drug supply system, and regular supervision are critical. All efforts should be made to treat patients on the spot, without delay, as referral to higher levels of care led to a high number of dropouts. The syndromic approach to STD control should be supported by at least one reference clinic and laboratory per country to ensure monitoring of prevalent aetiologies, of the development of bacterial resistance, and of the effectiveness of the syndromic algorithms in use.

The interrelation of HIV, cervical human papillomavirus, and neoplasia among antenatal clinic attenders in Tanzania.

OBJECTIVES: To determine the prevalence and interrelation of cervical human papillomavirus (HPV) genotypes, squamous intraepithelial lesions (SIL), HIV, and other reproductive tract infections (RTIs) among urban antenatal clinic attenders in Mwanza, Tanzania. METHODS: Genital swabs were collected from 660 pregnant women and tested for a range of RTIs and for cervical cytology. Cervical HPV-DNA was detected by PCR and genotyped. HIV and syphilis serologies were performed. RESULTS: HPV prevalence was 34% (209/612 women). Of the 144 typeable samples, 83% were high risk (HR-HPV) oncogenic strains (56% HPV 16 related types). SIL was detected in 43 women (7%), with high grade SIL in 3%. There was a high prevalence of HIV (15%), and of any RTI (83%). Genital warts were detected in 20 women (3%). HPV infection was associated with some behavioural factors (short duration of relationship, single status, not using condoms) and gonorrhoea. There was no overall association between HPV and HIV (OR=1.02, 95% CI 0.6-1.6), but a non-significant trend towards a stronger association with HR-HPV in women aged 15-19 (OR=2.79, 95% CI 0.8-9.5) and women aged > or =30 (OR=3.20, 95% CI 0.7-15). SIL was associated with HPV (OR=3.66, 95% CI 1.9-7.0), but not significantly with HIV (OR=1.54, 95% CI 0.7-3.4). Prevalence of SIL was higher among women dually positive for HPV/HIV compared to HPV infection only (21% v 12%), although this difference was not statistically significant (p=0.17). CONCLUSIONS: HPV infection was highly prevalent in this young antenatal population. The association of HIV with HR-HPV types in older women may suggest that the principal HIV/HPV interaction in this population is for HIV to upregulate HPV persistence, leading to subsequent development of SIL.

The reliability of a structured examination protocol and self administered vaginal swabs: a pilot study of gynaecological outpatients in Goa, India.

OBJECTIVES: Low participation rates for gynaecological examination and low reliability of clinical reporting of gynaecological examination findings are problems in community studies of gynaecological morbidity in India. This pilot study aimed to describe the reliability of a new examination protocol for recording the findings of gynaecological examination and the reliability and acceptability of the use of self administered vaginal swabs for the diagnosis of reproductive tract infections. METHOD: 75 women attending a gynaecology outpatient clinic were purposively sampled. Each woman was examined by two gynaecologists independently who recorded findings on the new examination protocol. Two swabs were collected from each woman, one by the gynaecologist and one by the woman. Swabs were smeared on separate slides which were stained and read for bacterial vaginosis and candidiasis by laboratory technicians blind to the mode of collection of the slides. RESULTS: The study showed a high inter-rater reliability for most of the items of the examination protocol. The interslide agreement for the diagnosis of the two RTIs was high. One third of women preferred the self administered swab. CONCLUSIONS: The examination protocol is a reliable method of recording gynaecological examination findings, and self administered swabs a useful way of obtaining vaginal specimens from women who did not wish to undergo gynaecological examinations in studies in the Indian setting.

Reliability of Omani women's self-reporting of gynaecologic morbidities.

OBJECTIVES: To assess the agreement of women's self-reports of gynaecologic morbidities (reproductive tract infections, RTIs; genital prolapse, and urinary tract infections, UTIs), physician's observations and the final diagnosis of these conditions. SUBJECTS AND METHODS: A nationally representative sample of 1,662 Omani women selected by a multi-stage, stratified probability-sampling procedure was included in the study. A questionnaire interview, physical and gynaecologic examination, and laboratory investigations were used. RESULTS: A total of 1,364 women completed all forms. The agreement between women's report of vaginal discharge and the diagnosis of RTI was poor. The sensitivity but not the specificity improved when the women were asked about specific discharge questions that upset them or are medically suspicious. Sensitivity of self-report in the diagnosis of genital prolapse and UTI from self-report was high but specificity was low. CONCLUSIONS: Self-report of vaginal discharge, coupled with clinical examination, can be used in community diagnosis of RTI. Self-report of symptoms of vaginal prolapse can also be used for community diagnosis of genital prolapse. A urinary culture should supplement self-reports of UTI to enhance specificity, although the presence of a positive culture in the absence of symptoms is of no clinical significance in non-pregnant women or women without renal disease.

Distribution of trimethoprim and sulfametopyrazine in the female reproductive tract.

A combination of trimethoprim (TMP) 250 mg and sulfametopyrazine (SMP) 200 mg (dose ratio 5:4) in capsules was administered to ten patients undergoing hysterectomy for uterine leiomyoma. Each patient received a total of 3 of these Kelfiprim capsules: 2 capsules in a single administration 36 hours before surgery and 1 capsule 24 hours later. TMP and SMP concentrations were analyzed in plasma and also in the ovary, Fallopian tube and uterus, removed during surgery. The results indicated that in the reproductive organs of the female genital tract TMP reaches the same concentrations as in plasma. In contrast SMP is 3 to 3.5 times less concentrated in these tissues compared with plasma. At the TMP/SMP ratios obtained in these various organs synergism of the two compounds is reported to be particularly prominent for most bacterial strains. These findings indicate that this TMP-SMP combination may be useful in the treatment of female reproductive tract infections.

Response to podophyllotoxin treatment of genital warts in relation to HIV-1 infection among patients in Dar es Salaam, Tanzania.

Forty-two Tanzanian patients with genital warts were treated with 0.5% podophyllotoxin solution (Wartec) for 3 days. Thirteen patients (30.9%) were cured and a further 7 patients (16.7%) had more than 50% of lesions cleared at 6 weeks, while 19 patients were resistant to treatment. Three patients had a recurrence of lesions after an initial response. Thirty-three patients were tested for serological evidence of infection with human immunodeficiency virus (HIV) and 15 (45.5%) patients were shown to be HIV-1 antibody positive. The response to treatment was analysed in relation to HIV antibody status. The cure rate was significantly higher in HIV seronegative patients (8/18 = 44.4%) compared to HIV seropositive patients (1/15 = 6.7%) (P = 0.018). We conclude that podophyllotoxin treatment provides a useful non-hospital based treatment for genital warts, but HIV infection appears to contribute to the failure of treatment for genital warts.

The meaning of RTI in Vietnam--a qualitative study of illness representation: collaboration or self-regulation?

In collaboration with the National Committee for Population and Family Planning, a study was conducted in a rural and urban commune of northern Vietnam to provide community-level information about women's reproductive health and behaviors. Ethnographic and structured interviews were conducted with 32 women. A psychosocial model of health behavior, the Dual Process Model, was applied to provide a theoretical framework for understanding women's interpretations of, and strategies for, coping with symptoms of reproductive tract infections (RTIs). Women were found to interpret and manage RTI symptoms collaboratively with other women. Therefore, women's approach to care seeking was influenced heavily by their peer network and not driven by their method of family planning.

A strategic assessment of cervical cancer prevention and treatment services in 3 districts of Uttar Pradesh, India.

BACKGROUND: Despite being a preventable disease, cervical cancer claims the lives of almost half a million women worldwide each year. India bears one-fifth of the global burden of the disease, with approximately 130,000 new cases a year. In an effort to assess the need and potential for improving the quality of cervical cancer prevention and treatment services in Uttar Pradesh, a strategic assessment was conducted in three of the state's districts: Agra, Lucknow, and Saharanpur. METHODS: Using an adaptation of stage one of the World Health Organization's Strategic Approach to Improving Reproductive Health Policies and Programmes, an assessment of the quality of cervical cancer services was carried out by a multidisciplinary team of stakeholders. The assessment included a review of the available literature, observations of services, collection of hospital statistics and the conduct of qualitative research (in-depth interviews and focus group discussions) to assess the perspectives of women, providers, policy makers and community members. RESULTS: There were gaps in provider knowledge and practices, potentially attributable to limited provider training and professional development opportunities. In the absence of a state policy on cervical cancer, screening of asymptomatic women was practically absent, except in the military sector. Cytology-based cancer screening tests (i.e. pap smears) were often used to help diagnose women with symptoms of reproductive tract infections but not routinely screen asymptomatic women. Access to appropriate treatment of precancerous lesions was limited and often inappropriately managed by hysterectomy in many urban centers. Cancer treatment facilities were well equipped but mostly inaccessible for women in need. Finally, policy makers, community members and clients were mostly unaware about cervical cancer and its preventable nature, although with information, expressed a strong interest in having services available to women in their communities. CONCLUSION: To address gaps in services and unmet needs, state policies and integrated interventions have the potential to improve the quality of services for prevention of cervical cancer in Uttar Pradesh.

An acceptability study of female-controlled methods of protection against HIV and STDs in south-western Uganda.

We aimed to assess the acceptability of a variety of formulations of female-controlled methods of protection against HIV and STDs among men and women in south-western Uganda. Pilot interviews were carried out with 50 men and 55 women and 25 focus group discussions (FGDs) were held with 138 women and 42 men. The female condom, foaming tablets, sponge, foam, gel and film were demonstrated to 146 women and 35 of their male partners, who then tried out 2 of the products. They were interviewed 7 times during the course of 5 months. At the end experiences were evaluated during a second series of FGDs. Sixty-five (45%) women completed the trial. The main reasons for non-completion were related to geographical mobility. Product preference after the initial demonstration was similar to that at the end of the trial. The most popular formulations were the sponge (25% of the women), foaming tablets (23%), and the female condom (19%). The foam was of medium popularity (16%). The gel (9%) and film (7%) were least popular. Ten per cent of the women and 14% of the men reported products interfering with sexual enjoyment; 24% of the women and 67% of the men said products increased enjoyment. 'Dry sex' is not popular in this area and increased lubrication was an important determinant of acceptability. Age, level of education and location did have some effect on preference. Although secrecy was a dominant theme in the FGDs, 87% of the women had informed their partners by the end of the trial. The products were generally well received. Female control was an important issue for both sexes. Male attitudes were ambivalent because female ownership of products increased women's control. Although they have clear preferences, women appear to accept the products generally and might use a single available product just as readily if choice was limited, as long as it conforms to general cultural preferences, such as those relating to wet/dry sex.

Determinants of condom-use behaviour among STD clinic attenders in South Africa.

This cross-sectional study analyses determinants of condom-use behaviour among patients attending dedicated STD clinics in South Africa. A structured interviewer-administered survey was conducted among 1473 patients. Patients' beliefs and attitudes towards condom use in general, as well as their personal condom-use behaviour were measured. Their perceptions, regarding the social influence of their partners and friends on their condom use, and of their self-efficacy in using condoms, while infected with an STD were also measured. Condom use, as a dependent variable, was examined and patients were placed in a pre-contemplation stage if they had never used a condom, contemplation if they had seriously thought of using a condom, some action stage if they sometimes used a condom and regular action stage if they used a condom every time. The relationships between the stages of change, as dependent variables, and the independent variables were investigated for both those patients with steady partners and those with outside partners. This was performed by stepwise multiple regression analyses. The variables that significantly explained stages of change were similar for patients with steady partners and those with outside partners. In both partner groups communication was the variable most strongly associated with the use of condoms. General self-efficacy in condom use, self-efficacy in condom use with a partner and attitudes towards the use of condoms played a role in determining patients' different stages of change.

Presumptive specific clinical diagnosis of genital ulcer disease (GUD) in a primary health care setting in Nairobi.

Of 22,274 patients 12 years of age or older attending a primary health care clinic in Nairobi, 1076 (4.8%) complained of symptoms suggesting a sexually transmitted disease (STD). Of these, 518 females and 462 males underwent complete clinical evaluation, and 78% had objective microbiologic or clinical evidence of STD, including 168 (17.1%) with genital ulcer disease (GUD). Presumptive specific clinical diagnoses on initial physical examination in cases of GUD were chancroid (131 patients), syphilis (25), genital herpes (15) and lymphogranuloma venereum (LGV) (1). Clinical diagnoses correlated only weakly with microbiological and serological diagnoses. Haemophilus ducreyi was isolated from 51 (41%) of the 125 with a clinical diagnosis of chancroid, and 4 (22%) of 18 with a diagnosis of syphilis, herpes, or LGV (P = 0.13). The rapid plasma reagin (RPR) test was reactive in 6 (24%) of 25 with a clinical diagnosis of syphilis, 18 (12.3%) of 146 with a diagnosis of chancroid or herpes, and 37 (4.7%) of 786 without a genital ulcer (P < 0.001, GUD vs no GUD). Sensitivity, specificity, and positive predictive value for presumptive clinical diagnosis of chancroid, relative to H. ducreyi isolation, were 93%, 16%, and 41%; and for diagnosis of syphilis, relative to reactive RPR, were 25%, 88% and 25%. Specific treatment based on presumptive specific clinical diagnosis frequently was inadequate for syphilis among patients with GUD and reactive RPR test. Syndromic treatment of GUD with antimicrobial combinations active against both chancroid and syphilis would be preferable to treatment with single drugs based on presumptive specific clinical diagnoses for this population.

Antimicrobial self medication in patients attending a sexually transmitted diseases clinic.

One of the health education messages given in sexually transmitted disease (STD) control is patients' adopting appropriate health seeking behaviour. This includes reporting to health facilities for appropriate diagnosis and treatment. In parts of the world where STD aetiologic agents have assumed resistance to commonly used antimicrobials, this is important. The antimicrobial self medication practices of 764 patients attending an STD clinic in a developing country were studied. Seventy-four and a half per cent admitted to self medication before reporting to the clinic. The antibiotics taken in inappropriate dosages were purchased over the counter, given by friends or were 'left-overs' from previous medications. In the fight to control STD spread as a means of reducing the incidence of HIV/AIDS, indiscriminate use of antimicrobials needs to be guarded against.

Genital ulcers in a primary health clinic in Rwanda: impact of HIV infection on diagnosis and ulcer healing (1986-1992).

During 1986-88 and 1990-92, 1025 (97%) out of 1057 genital ulcer patients in Kigali, Rwanda, were tested for HIV antibodies and for infection with Treponema pallidum, Haemophilus ducreyi and herpes simplex virus. Overall, 57% of men and 80% of women had antibodies to HIV-1. The most frequent laboratory diagnoses were chancroid (27%), syphilis (19%) and genital herpes (19%) among men and syphilis (35%), genital herpes (23%) and chancroid (20%) among women. HIV-1 seroprevalence increased sharply over time among men but not among women. The clinical presentation of ulcers as well as laboratory diagnoses were similar in the HIV-1 seropositive and seronegative groups. The relative frequency of all laboratory diagnoses remained unchanged over time. HIV-1 seropositivity had no impact on ulcer healing. Advanced immunodeficiency was diagnosed among 12% of the HIV-1 seropositive patients and was significantly associated with increasing age and genital herpes.

Andrological evaluation of oligozoospermic men for AIH.

A protocol for the assessment of oligozoospermia prior to AIH is presented. Three to six carefully performed semen analyses at optimal intervals are required to confirm oligozoospermia. Routine semen analysis consist of volume, pH, viscosity, sperm count, motility, morphology, agglutination, fructose content, and leukocytes. Because of the high incidence of reproductive tract infection and chromosomal abnormalities in oligozoospermic men, microbiological investigation and full chromosomal analyses should be performed in all cases with sperm counts below 10 million/ml. Chromosomal abnormalities are an indication to reject a couple from AIH. Genital tract infections must be treated prior to insemination. Only sperm counts below 10 million/ml require the estimation of FSH levels. The existence of an oligozoospermia group with pituitary adenoma justifies routine PRL measurements in all cases of oligozoospermia and further investigations such as visual field examination and sella tomogram in case of hyperprolactinemia. Testicular biopsy may indicate an epididymal block that can be surgically repaired. Simultaneous in-depth evaluation of the female partner is emphasized, as oligozoospermia in the man does not rule out the possibility of an additional infertility factor in his partner. It is still controversial whether or not AIH, as compared to intercourse, will improve the conception rate for oligozoospermic men.

Susceptibility pattern of Neisseria gonorrhoeae to antimicrobial agents in Dar es Salaam.

OBJECTIVE: To determine the susceptibility pattern of local strains of Neisseria gonorrhoeae from Dar es salaam, Tanzania to locally used antibiotics. METHOD: Out of 429 Neisseria gonorrhoeae strains isolated between 1993 and 1995, one hundred and ninety nine were recovered and tested. Minimum inhibitory concentrations (MIC) of penicillin, doxycycline, erythromycin, cefuroxime and ciprofloxacin were determined by the E-test method while that of spectinomycin was measured by the agar dilution method. Penicillinase producing N. gonorrhoeae were identified by the chromogenic cephalosporin method. RESULTS: Of the 199 strains tested 128 (64%) were found to be penicillinase producing Neisseria gonorrhoeae (PPNG). Only 19 (10%) were penicillin sensitive while all penicillin resistant strains were found to be PPNG. One hundred and seventy five (88%), 11(5%) and 13 (7%) of the tested isolates were resistant, less susceptible and fully susceptible to doxycycline respectively. Resistance to cotrimoxazole, cefuroxime and ciprofloxacin was 36 (18%), 11 (6%), and 3 (2%) respectively. The trend of antibiotic susceptibility rates over the three year period of study showed a significant increase in the proportion of susceptible strains to cotrimoxazole. All of the 75 strains tested against spectinomycin were susceptible. There was a statistically significant difference between the susceptibility patterns of non-PPNG and PPNG. Non-PPNG isolates were more susceptible to doxycycline (chi 2 = 78.2, df 2, p = < 0.0001). CONCLUSION: These findings have shown that spectinomycin, ciprofloxacin and cefuroxime could continue to be used to treat gonorrhoea in our settings. Continuous surveillance of susceptibility to the commonly used antibiotics is important in order to detect emergence of resistance early and control the possible wide spread of resistant strains.

Reproductive health and STDs among clients of a women's health mobile clinic in rural Bali, Indonesia.

Recent studies in Indonesia have reported significant levels of STDs in low-risk urban groups. To gather data on rural women, a prevalence study was undertaken in Bali utilizing a women's health mobile clinic. Rural (n=312) women were tested for vaginal reproductive tract infections (RTIs) by on-site wet mount, for Neisseria gonorrhoeae and Chlamydia trachomatis by unamplified DNA (Gen-Probe) test, and for syphilis by rapid plasma reagin (RPR). Results were: candidiasis 5.8%; bacterial vaginosis (BV) 37.2%; trichomoniasis 15.1%; gonorrhoea 0.7%; chlamydial infection 5.6%; syphilis 0%. Overall 55.1% had at least one RTI and 19.2% had at least one STD. Reported non-monogamy, pain with urination and genital lesions, observed cervical friability and cervical motion tenderness were associated with cervical STD infection (P<0.05). We conclude that there is a need for improved services for STD prevention and RTI/STD management in rural Bali, and for condom promotion.
