Co-infections associated with human immunodeficiency virus type 1 in pregnant women from southern Brazil: high rate of intraepithelial cervical lesions

Human immunodeficiency virus type 1 (HIV-positive) pregnant women require specific prophylactic and therapeutic approaches. The efficacy of established approaches is further challenged by co-infection with other sexually transmitted diseases (STDs). The objective of this study was to determine the prevalence of co-infections in pregnant women infected with different HIV-1 subtypes and to relate these findings, together with additional demographic and clinical parameters, to maternal and infant outcomes. Blood samples from pregnant women were collected and tested for syphilis, hepatitis B virus (HBV) and hepatitis C virus (HCV). Human papillomavirus (HPV) diagnosis was evaluated by the presence of alterations in the cervical epithelium detected through a cytopathological exam. Medical charts provided patient data for the mothers and children. Statistical analyses were conducted with STATA 9.0. We found a prevalence of 10.8% for HCV, 2.3% for chronic HBV, 3.1% for syphilis and 40.8% for HPV. Of those co-infected with HPV, 52.9% presented high-grade intraepithelial lesions or in situ carcinoma. Prematurity, birth weight, Apgar 1' and 5' and Capurro scores were similar between co-infected and non-co-infected women. The presence of other STDs did not impact maternal and concept outcomes. More than half of the patients presenting cervical cytology abnormalities suggestive of HPV had high-grade squamous intraepithelial lesions or cervical cancer, evidencing an alarming rate of these lesions.

Situation des personnes transgenres par rapport au VIH/IST en Suisse : rapid assessment

Ce rapport permet d'identifier le sous-groupe des personnes transgenres pratiquant ou ayant pratiqué le travail du sexe comme une population clairement exposée à un risque notoirement élevé d'infection par le VIH et les IST. L'ampleur rapportée du phénomène justifie pleinement l'inclusion de cette population dans le dispositif de surveillance comportementale du VIH et des autres IST, mais également la réalisation urgente d'actions de prévention communautaire. Par contre, il ne nous permet pas d'arriver à un consensus fort en ce qui concerne la situation des personnes transgenres non travailleuses du sexe par rapport au VIH et aux autres IST en Suisse. Les données internationales sont cependant suffisamment préoccupantes pour justifier la réalisation d'une recherche sur la santé sexuelle au sein de cette population. Cette recherche devra prendre en compte les contextes de vie souvent hostiles auxquels sont confrontées les personnes transgenres. Par ailleurs, les personnes transgenres devraient pouvoir être reconnues en tant que telles et enregistrées de manière systématique dans les systèmes de déclaration du VIH et des autres IST, dans les outils de suivi statistique des centres de dépistage et de conseil VIH/IST, ainsi que dans l'enquête suisse sur la santé.

Iron overload, an immunosuppression marker in HIV-infected patients.

Purpose: Iron overload (IO) has been associated with increased cardiovascular risk (CVR) and metabolic syndrome (MS) in the general population; both elevated CVR and MS are frequent in HIV- patients. Our aim was to analyze the prevalence of IO in a cohort of asymptomatic patients with HIV infection, and related factors. Methods: Cross-sectional study of a cohort of HIV outpatients in regular follow-up. Demographic, epidemiological, clinical, analytical and therapeutic data were collected. Patients completed a questionnaire about CVR factors and 10-year CV disease risk estimation (Framingham score), underwent a physical exam, and a fasting blood analysis. IO was defined as a plasma ferritin level higher than 200 m/L in women and 300 m/L in men. Results: 571 patients (446 men, 125 women), with a mean age of 43.2 years, sexual transmission of HIV in 68.5%, median CD4 count 474 cell/μL (IQR: 308-666), and 36.3% Aids cases 86.2% were on antiretroviral therapy (ART), and 74.8% of them had undetectable HIV viral load 14.6% met MS criteria, and mean CVR at 10 years was 6.67%. IO was detected in 11% of cases. Patients with IO were more immunosuppressed (CD4 count 369 vs 483/μL, p<0.0001), presented a higher prevalence of detectable HIV viral load (17.6% vs 8.9%; p<0.005), and of Aids cases (14.9% vs 8.7%; p<0.023), and lower plasma levels of cholesterol, HDLc and LDLc (154 vs 183, 34 vs 43, 93 vs 110 mg/dL, respectively; p<0.0001. In the multivariate analysis, the only related factor was CD4 count <350 cell/μL (OR 2.86, 95% CI 1.6-4.9; p<0.0001). IO was not associated with CVR nor with MS. Conclusions: IO is not uncommon in HIV patients, and it is only related with immunosuppression defined as CD4 count <350 cell/ mL, and in contrast to general population, it is not related with increased CVR nor with MS.

Association of human papillomavirus and Chlamydia trachomatis with intraepithelial alterations in cervix samples

The influence of different infectious agents and their association with human papillomavirus (HPV) in cervical carcinogenesis have not been completely elucidated. This study describes the association between cytological changes in cervical epithelium and the detection of the most relevant aetiological agents of sexually transmitted diseases. Samples collected from 169 patients were evaluated by conventional cytology followed by molecular analysis to detect HPV DNA, Chlamydia trachomatis, herpes simplex virus 1 and 2,Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, andTreponema pallidum, besides genotyping for most common high-risk HPV. An association between cytological lesions and different behavioural habits such as smoking and sedentariness was observed. Intraepithelial lesions were also associated with HPV and C. trachomatis detection. An association was also found between both simple and multiple genotype infection and cytological changes. The investigation of HPV and C. trachomatisproved its importance and may be considered in the future for including in screening programs, since these factors are linked to the early diagnosis of patients with precursor lesions of cervical cancer.

The role of polymerase chain reaction of high-risk human papilloma virus in the screening of high-grade squamous intraepithelial lesions in the anal mucosa of human immunodeficiency virus-positive males having sex with males.

OBJECTIVES To evaluate the advantages of cytology and PCR of high-risk human papilloma virus (PCR HR-HPV) infection in biopsy-derived diagnosis of high-grade squamous intraepithelial lesions (HSIL = AIN2/AIN3) in HIV-positive men having sex with men (MSM). METHODS This is a single-centered study conducted between May 2010 and May 2014 in patients (n = 201, mean age 37 years) recruited from our outpatient clinic. Samples of anal canal mucosa were taken into liquid medium for PCR HPV analysis and for cytology. Anoscopy was performed for histology evaluation. RESULTS Anoscopy showed 33.8% were normal, 47.8% low-grade squamous intraepithelial lesions (LSIL), and 18.4% HSIL; 80.2% had HR-HPV. PCR of HR-HPV had greater sensitivity than did cytology (88.8% vs. 75.7%) in HSIL screening, with similar positive (PPV) and negative predictive value (NPV) of 20.3 vs. 22.9 and 89.7 vs. 88.1, respectively. Combining both tests increased the sensitivity and NPV of HSIL diagnosis to 100%. Correlation of cytology vs. histology was, generally, very low and PCR of HR-HPV vs. histology was non-existent (<0.2) or low (<0.4). Area under the receiver operating characteristics (AUROC) curve analysis of cytology and PCR HR-HPV for the diagnosis of HSIL was poor (<0.6). Multivariate regression analysis showed protective factors against HSIL were: viral suppression (OR: 0.312; 95%CI: 0.099-0.984), and/or syphilis infection (OR: 0.193; 95%CI: 0.045-0.827). HSIL risk was associated with HPV-68 genotype (OR: 20.1; 95%CI: 2.04-197.82). CONCLUSIONS When cytology and PCR HR-HPV findings are normal, the diagnosis of pre-malignant HSIL can be reliably ruled-out in HIV-positive patients. HPV suppression with treatment protects against the appearance of HSIL.

Comportamiento anticonceptivo en estudiantes universitarios y riesgo de infección con el virus de inmunodeficiencia humana (VIH)

Se examinan los comportamientos anticonceptivos de 225 jóvenes universitarios (22'7% hombres y 77'3% mujeres) con el objetivo de conocer su eficacia para evitar embarazos no deseados, SIDA y otras enfermedades de transmisión sexual (ETS). Se recogió información sobre los diferentes métodos anticonceptivos empleados por los sujetos con su última pareja, sin establecer ningún límite temporal. La mitad de los estudiantes no habían tenido nunca relaciones sexuales completas. La mitad de las conductas heterosexuales de los jóvenes sexualmente activos fueron adecuadas para protegerse frente al SIDA, otras ETS y embarazos no deseados (usar siempre preservativo); un tercio de las conductas únicamente eran útiles para evitar embarazos (píldora anticonceptiva) y las restantes (usar ocasionalmente el preservativo o el coitus interruptus ) les pusieron en riesgo frente a los tres problemas. Además, conforme se eleva la edad o el número de parejas de los estudiantes, es más frecuente el uso de píldoras anticonceptivas y menos probable el empleo de preservativo. Estos resultados sugieren que los estudiantes sexualmente activos están más interesados en la prevención de los embarazos no deseados que en evitar infectarse con el SIDA u otras ETS, por lo que seria conveniente promocionar entre ellos el uso del preservativo como método anticonceptivo, destacando sus ventajas frente a la píldora

Prevención de la transmisión sexual del VIH en adolescentes

En una muestra de 119 estudiantes de cuarto de Educación Secundaria Obligatoria (ESO) y primerode Bachillerato (52,6% mujeres) se analizan los conocimientos sobre la prevención de latransmisión sexual del virus del sida, las expectativas de resultados y de autoeficacia respecto a losmétodos preventivos y el tipo de prevención utilizada durante la última relación sexual. Para evitarlas respuestas inducidas respecto a los comportamientos preventivos se emplea un formato de preguntaabierta. Los resultados muestran que sólo el 23,5% de los estudiantes han dado dos respuestastotalmente correctas sobre estrategias consideradas eficaces en la prevención sexual del VIH:uso del preservativo y abstinencia (por este orden). El 70,5% valoran totalmente o muy eficaz elpreservativo para evitar la transmisión sexual del VIH y el 95% de los que dan la segunda respuestajuzgan totalmente eficaz la práctica de la abstinencia con la misma finalidad. En el caso del preservativose sienten totalmente o muy capaces de usarlo el 64,3%, mientras que cuando se trata de laabstinencia sólo se perciben con esa competencia el 20%. Por lo que se refiere al uso autoinformadode métodos preventivos en la última relación, por parte de los 29 estudiantes que tuvieronactividad sexual durante el mes anterior, se observa que 21 de ellos emplearon el preservativo, dosla píldora anticonceptiva, otros dos no precisan el tipo de precaución y el resto no tomó ninguna.Tanto el reducido nivel de conocimientos sobre prevención, como la baja percepción de autoeficaciapara mantenerse abstinentes, nos alertan sobre la necesidad de hacer un mayor esfuerzo de informaciónpara eliminar creencias equivocadas, como por ejemplo: sobre la pretendida eficacia protectorade tener relaciones sexuales con una pareja estable o conocida. Así mismo, conviene insistiren el uso del preservativo como anticonceptivo de elección entre los adolescentes

Influencia social y uso del preservativo en la prevención de la transmisión heterosexual del VIH = Social influence and condom use for VIH heterosexual transmission prevention

Se revisan diferentes formas en que la influencia social puede incidir sobre los comportamientosheterosexuales de prevención de la transmisión del VIH de los jóvenes y se presentanlos resultados de algunos trabajos de las autoras, así como de otros investigadores, en que seanalizan dichas relaciones. Se concluye resaltando: 1) la utilidad clínica de la evaluación de lasexpectativas de autoeficacia para poder intervenir específicamente en aquellas áreas en que losjóvenes se perciban con menores capacidades para ser preventivos, 2) la relación observadaentre el uso de preservativo autoinformado y la creencia en su aceptación por parte de los referentessociales más cercanos y 3) la conveniencia de que los jóvenes posean suficientes habilidadesde comunicación que les permitan negociar con éxito el uso del preservativo y les ayudena compensar posibles influencias sociales en contra de su empleo

Talking about sexuality with the physician: are patients receiving what they wish?

QUESTIONS UNDER STUDY/PRINCIPLES: Little is known concerning patients' expectations regarding sexual history taking by doctors: to ascertain expectations and actual experience of talking about sexuality among male patients attending outpatient clinics, and their sexual behaviour. METHODS: Patients consecutively recruited from two outpatient clinics in Lausanne, Switzerland were provided with an anonymous self-administered questionnaire. Survey topics were: patients' expectations concerning sexual history taking, patients' lifetime experience of sexual history taking, and patients' sexual behaviour. RESULTS: The response rate was 53.0% (N = 1452). Among respondents, 90.9% would like their physician to ask them questions regarding their sexual history in order to receive advice on prevention (60.0% yes, 30.9% rather yes). Fifteen percent would be embarrassed or rather embarrassed if asked such questions. Nevertheless, 76.2% of these individuals would like their physician to do so. Despite these wishes, only 40.5% reported ever having a discussion "on their sexual life in general" with a doctor. Only one patient out of four to five was asked about previous sexually transmitted infections (STIs), the number of sexual partners and their sexual orientation. No feature of their sexual life distinguishes those who had discussed sexual issues with a doctor from those who had not, except a history of previous consultation for health problems related to sexuality. Conversely, being embarrassed about conducting this discussion was significantly associated with lack of discussion regarding sexuality. CONCLUSIONS: This study highlights the gap existing in the field of STI prevention in terms of doctors' advice and patients' wishes.

Epidemiological Profile for Iowa, 2002

This statewide profile describes the epidemiology of HIV, AIDS, and other sexually transmitted diseases in Iowa through December, 2002. The report characterizes the distribution of these diseases in terms of geography, race, gender, age, and associated causal factors. This epidemiological profile has been prepared to assist in developing a comprehensive HIV/AIDS Prevention and Care Plan. This description of the HIV epidemic in the state serves to guide prevention and service efforts, to quantify unmet need for prevention and care programs, and to evaluate programs and policies in Iowa. Five key questions are addressed: 1. What are the sociodemographic characteristics of Iowa’s population? 2. What is the epidemiology, including the geographical distribution, of HIV, AIDS, and other sexually transmitted diseases (STDs) in Iowa? 3. Who is at the greatest risk of becoming infected with HIV and other STDs in Iowa? 4. What are the patterns of utilization of HIV services throughout the state? 5. What are the number and characteristics of persons who know they are HIV-positive, but who are not receiving primary medical care?

Assessing AIDS/HIV prevention: what do we know in Europe?

An EC concerted action on the assessment of AIDS/HIV prevention strategies was conducted between 1989 and 1992. The aim of this concerted action (CA) was to bring together researchers who are active in this assessment field, make an initial appraisal of the results of AIDS prevention efforts, in various population groups in Europe and develop an assessment methodology. Five areas of study were selected for the CA: the population as a whole ("general population"), men who have sexual relations with other men, intravenous drug users, migrant populations, monitoring of sexually transmitted diseases (STDs) to determine changes in behaviour. For each of these areas, a working group composed of the leading researchers in the field in Europe was constituted and commissioned by the project administration and coordination team to collate and analyse data on prevention efforts and their assessment in different countries of Europe. This review presents the main results from the groups responsible in each area in the concerted action. A number of general conclusions from the results of this concerted action are drawn.
