Human papillomavirus types in women with invasive cervical carcinoma by HIV status in Kenya

To evaluate the fraction of invasive cervical carcinoma (ICC) that could be prevented in HIV-infected women by vaccines currently available against human papillomavirus (HPV)16 and 18, we conducted a cross-sectional study in women with ICC in Nairobi, Kenya. Fifty-one HIV-positive women were frequency-matched by age to 153 HIV-negative women. Cervical cells were tested for HPV DNA using polymerase chain reaction-based assays (SPF10-INNO-LiPA). Comparisons were adjusted for multiplicity of HPV types. As expected, multiple-type infections were much more frequent in HIV-positive (37.2%) than in HIV-negative (13.7%) women, but the distribution of HPV types was similar. HPV16 was detected in 41.2% versus 43.8% and HPV16 and/or 18 in 64.7% versus 60.1% of HIV-positive versus HIV-negative women, respectively. The only differences of borderline statistical significance were an excess of HPV52 (19.6% versus 5.2%) and a lack of HPV45 (7.8% versus 17.0%) in HIV-positive women compared to HIV-negative women, respectively. We have been able to assess an unprecedented number of ICCs in HIV-positive women, but as we did not know the age of HIV acquisition, we cannot exclude that it had occurred too late in life to affect the type of HPV involved in cervical carcinogenesis. However, if our findings were confirmed, they would suggest that the efficacy of current vaccines against HPV16 and 18 to prevent ICC is similar in HIV-positive and HIV-negative women, provided vaccination is administered before sexual debut, as recommended.     

Repeat abortion in Chinese adolescents: a cross-sectional study in 30 provinces

Background

Premarital sex has become more acceptable in China nowadays. The Chinese Family Planning (FP) programme mainly focuses on married couples, and young unmarried women have little access to information or advice about contraception. Abortion is commonly used to end unintended pregnancies in China. This study aimed to determine risk factors related to repeat abortions in Chinese adolescents.

CEPHEUS SA: a South African survey on the undertreatment of hypercholesterolaemia

Aim

The aim of the CEntralised Pan-South African survey on tHE Under-treatment of hypercholeSterolaemia (CEPHEUS SA) was to evaluate the current use and efficacy of lipid-lowering drugs (LLDs), and to identify possible patient and physician characteristics associated with failure, if any, to achieve low-density lipoprotein cholesterol (LDL-C) targets.

Methods

The survey was conducted in 69 study centres in South Africa and recruited consecutive consenting patients who had been prescribed LLDs for at least three months. One visit was scheduled for data collection, including fasting plasma lipid and glucose levels. Physicians and patients completed questionnaires regarding their knowledge, awareness and perceptions of hypercholesterolaemia and the treatment thereof.

Results

Of the 3 001 patients recruited, 2 996 were included in the final analyses. The mean age was 59.4 years, and 47.5% were female. Only 60.5 and 52.3% of patients on LLDs for at least three months achieved the LDL-C target recommended by the NCEP ATP III/2004 updated NCEP ATP III and the Fourth JETF/South African guidelines, respectively. Being male, older than 40 years, falling into the lower-risk categories, compliance with the medication regimen, and patient knowledge that the LDL-C goal had been reached, were associated with the highest probability of attaining LDL-C goals.

Conclusion

The results of this survey highlight the sub-optimal lipid control achieved in many South African patients taking lipid-lowering therapy.     

Reproductive health indicators in the European Union: The REPROSTAT project

Our objective was to develop a set of indicators for monitoring and describing reproductive health in the European Union (EU) that reflect common concerns of the different Member States. Ideally, the indicators would possibly draw upon existing data sources. The REPROSTAT project: (i) conducted a review of existing recommendations on reproductive health indicators; (ii) suggested a set of initial indicators in consultation with representatives from relevant outside agencies and organisations; and (iii) invited 200 reproductive health experts throughout Europe to review the provisional set of indicators. The feasibility of using the REPROSTAT indicators was tested for two countries, Italy and Germany. A final set of 13 core indicators was developed, as well as another recommended indicator and four that needed further development. The pilot use of the indicators in Italy and Germany provided useful information about availability of data in different Member States. The REPROSTAT project developed a set of reproductive health indicators believed to be of relevance for planning, prevention, and caring within the EU. Further, harmonisation of data from different Member States will be needed if the benefits of these indicators are to be fully realised.     

Prevalence and risk factors of sexually transmitted infections and cervical neoplasia in women's health clinics in Nicaragua

OBJECTIVES: To determine prevalence and risk factors of sexually transmitted infections (STIs), HIV, and cervical neoplasia in women attending women's health clinics in Nicaragua, and to assess the potential impact of screening for these diseases. METHODS: Consecutive women attending women's health clinics in different regions were interviewed and examined for STI, HIV, and cervical neoplasia. RESULTS: Whereas only 30.4% of the 1185 participating women attended the clinics because of STI related complaints, 77.0% reported symptoms after probing. Clinical cervicitis was diagnosed in 32.8%, Chlamydia trachomatis in 4.1%, gonorrhoea in 0.4%, trichomoniasis in 10.2%. Antibodies for syphilis were found in 0.7%, for hepatitis B in 3.7%, and none were HIV seropositive. The STI prevalence was 21.8% in women offending with complaints, 17.3% in symptomatic women after probing, and 14.8% in asymptomatic women. Abnormal Papanicolaou (Pap) smears were found in 7.7%, with high risk human papilloma virus (HPV) types in almost 60%. Male promiscuity was associated with high grade squamous intraepithelial lesions (HSIL) and reported former screening was not shown to be protective. Young age and being employed were risk factors for C. trachomatis. CONCLUSION: Nearly one out of five women attending women's health clinics in Nicaragua had an STI, and one out of 13 a precancerous lesion of the cervix. These clinics provide an opportunity to improve the reproductive health of women by probing for STI symptoms, especially in young women, and by offering cervical screening to casual attendees. Of concern is the high rate of cervical lesions in women with a screening history, underlining the need for proper quality control.     

Effectiveness of a peer-led HIV prevention intervention in secondary schools in Rwanda: results from a non-randomized controlled trial

ABSTRACT: BACKGROUND: While the HIV epidemic is levelling off in sub-Saharan Africa, it remains at an unacceptably high level. Young people aged 15-24 years remain particularly vulnerable, resulting in a regional HIV prevalence of 1.4% in young men and 3.3% in young women. This study assesses the effectiveness of a peer-led HIV prevention intervention in secondary schools in Rwanda on young people's sexual behavior, HIV knowledge and attitudes. METHODS: In a non-randomized longitudinal controlled trial, fourteen schools were selected in two neighboring districts: Bugesera (intervention) and Rwamagana (control). Students (n = 1950) in eight intervention and six control schools participated in three surveys (baseline, six and twelve months in the intervention). Analysis was done using linear and logistic regression using generalized estimation equations adjusted for propensity score. RESULTS: The overall retention rate was 72%. Time trends in sexual risk behavior (being sexually active, sex in last six months, condom use at last sex) were not significantly different in students from intervention and control schools, nor was the intervention associated with increased knowledge, perceived severity or perceived susceptibility. It did significantly reduce reported stigma. CONCLUSIONS: Analyzing this and other interventions, we identified several reasons for the observed limited effectiveness of peer education: 1) intervention activities (spreading information) are not tuned to objectives (changing behavior); 2) young people prefer receiving HIV information from other sources than peers; 3) outcome indicators are not adequate and the context of the relationship in which sex occurs. Effectiveness of peer education may increase through integration in holistic interventions and redefining peer educators' role as focal points for sensitization and referral to experts and services. Finally, we argue that a narrow focus on sexual risks will never significantly turn the tide.     

Female sex work and international sport events - no major changes in demand or supply of paid sex during the 2010 Soccer World Cup: a cross-sectional study

ABSTRACT: BACKGROUND: Important unanswered questions remain on the impact of international sporting events on the sex industry. Speculation about increased demand and supply of sex work often generates significant attention, but also additional funding for HIV programmes. This study assessed whether changes occurred in the demand and supply of paid sex during the 2010 Soccer World Cup in South Africa. METHODS: Trained sex worker interviewers conducted face-to-face semi-structured interviews among consenting female sex workers during May-September 2010. Using bivariate analyses we compared supply, demand, sexual risk-taking, and police and health services contact pre-World Cup, to levels during the World Cup and after the event. RESULTS: No increases were detected in indicators of sex work supply, including the proportion of sex workers newly arrived in the city (< 2.5% in each phase) or those recently entering the trade (<= 1.5%). Similarly, demand for sex work, indicated by median number of clients (around 12 per week) and amount charged per transaction ($13) remained similar in the three study periods. Only a third of participants reported observing any change in the sex industry ascribed to the World Cup. Self-reported condom-use with clients remained high across all samples (> 92.4% in all phases). Health-care utilisation decreased non-significantly from the pre- to during World Cup period (62.4% to 57.0%; P = 0.075). Across all periods, about thirty percent of participants had interacted with police in the preceding month, two thirds of whom had negative interactions. CONCLUSIONS: Contrary to public opinion, no major increases were detected in the demand or supply of paid sex during the World Cup. Although the study design employed was unable to select population-based samples, these findings do not support the public concern and media speculation prior to the event, but rather signal a missed opportunity for public health action. Given the media attention on sex work, future sporting events offer strategic opportunities to implement services for sex workers and their clients, especially as health service utilisation might decrease in this period.     

Detection of human immunodeficiency virus type 1 (HIV-1) in heel prick blood on filter paper from children born to HIV-1-seropositive mothers.

The human immunodeficiency virus type 1 (HIV-1) DNA PCR results of 94 dried blood spot (DBS) samples on filter paper and corresponding venous blood in EDTA obtained from infants born to HIV-1-seropositive mothers were compared. In addition, the results of HIV-1 DNA PCR on DBS and the HIV-1 RNA PCR from plasma of 70 paired samples were compared. A 100% specificity and a 95% sensitivity for HIV-1 DNA PCR on DBS compared with results for venous blood were observed for the 94 paired samples. The results of the DBS HIV-1 DNA PCR and HIV-1 RNA PCR of 70 corresponding plasma samples correlated perfectly (100%). The DBS HIV-1 DNA PCR method proved reliable for HIV-1 detection.     

Puncture of unilateral renal cyst in utero

Although most authors do not recommend prenatal puncture of a unilateral single cystic renal mass, in case the contralateral kidney is normal and there is sufficient amniotic fluid, this case report shows that the procedure, which can be done very carefully under ultrasonic guidance, can be helpful in establishing the presumed diagnosis.     

HIV and cervical cancer in Kenya.

OBJECTIVES: To determine the effect of the HIV epidemic on invasive cervical cancer in Kenya. METHODS: Of the 3902 women who were diagnosed with reproductive tract malignancies at Kenyatta National Hospital (KNH) from 1989 to 1998, 85% had invasive cervical cancer. Age at presentation and severity of cervical cancer were studied for a 9-year period when national HIV prevalence went from 5% to 5-10%, to 10-15%. RESULTS: There was no significant change in either age at presentation or severity of cervical cancer. Of the 118 (5%) women who were tested for HIV, 36 (31%) were seropositive. These women were 5 years younger at presentation than HIV-negative women. CONCLUSIONS: A two- to three-fold increase in HIV prevalence in Kenya did not seem to have a proportional effect on the incidence of cervical cancer. Yet, HIV-positive women who presented with cervical cancer were significantly younger than HIV-negative women.
