RESUMO

BACKGROUND: There is a limited understanding about the impact of spiritual beliefs and activities on HIV seroconversion among black men who have sex with men (BMSM), which we investigate in this study. SETTING: United States. METHODS: The HIV Prevention Trials Network Study 061 collected demographic and biomedical assessments among BMSM across 6 United States cities for longitudinal analysis. Spiritual beliefs and spiritual activities are constructed composite scales. Bivariate analyses among 894 who provided data at 12-month follow-up compared men who seroconverted to HIV between baseline and 6 months with those who remained uninfected with HIV at 12 months. Cox proportional hazard regression among 944 men tested spiritual beliefs and activities on the longitudinal risk of HIV seroconversion adjusting for age and any sexually transmitted infection (STI). RESULTS: Among this sample, HIV incidence between baseline and 6 months was 1.69%, (95% confidence intervals [CI]: 1.04 to 2.77). Men who seroconverted to HIV were significantly younger than those who remained uninfected at the 12-month follow-up: (mean age 27, SD = 11 vs 37, SD = 12) and a higher proportion reported any STI (46.67% vs 11.39%, P < 0.01). A one-unit increase in spiritual beliefs was associated with lower hazard rate of seroconverting to HIV at follow-up [adjusted hazard ratio (aHR) = 0.37, 95% CI: = (0.16 to 0.87)]. Religious service attendance and spiritual activities were unrelated to seroconverting. CONCLUSIONS: Spirituality is important in the lives of BMSM. Biomedical and behavioral HIV prevention interventions should consider assessing spiritual beliefs in HIV care among BMSM.

RESUMO

Background: Human immunodeficiency virus (HIV) infection constitutes a major medical complication of pregnancy and is associated with adverse feto-maternal outcomes. However, the relationship between maternal serum selenium levels and pregnancy outcomes has been inconsistent. Objective: This study aimed to determine the relationship between maternal serum selenium status and pregnancy outcome in HIV-positive and HIV-negative women in a tertiary health facility. Methodology: A.comparative cross-sectional study was carried out among HIV-positive and HIV-negative pregnant women at a tertiary health-care facility in Owerri. Participants were recruited from the labor ward and interviewed using a structured questionnaire. One hundred and ten HIV-positive pregnant women were compared with an equal number of HIV-negative pregnant women. They were matched for age, parity and gestational age. Selenium level was measured using atomic absorption spectrophotometer. Maternal packed cell volume (PCV) was also assessed at recruitment. At delivery, the birth weight was measured using a standard weighing scale and documented. Cases of preterm births, perinatal deaths, major congenital abnormalities, and neonatal admission were noted and also documented. Statistical analysis was performed using means and standard deviation. Chi-square test, Student's t-test, logistic regression, and Pearson correlation were also employed. Statistical significance was considered at P < 0.05. Results: HIV-positive pregnant women had significantly lower mean serum selenium concentration compared with HIV-negative pregnant women (64.3 ± 19.6 µg/L vs. 100.1 ± 30.9 µg/L; P < 0.001). There was a statistically significant association between serum selenium concentration and birth weight among both HIV-positive and HIV-negative pregnant women (P < 0.001). Similarly, a statistically significant association was seen between serum selenium and maternal PCV in HIV-positive and HIV-negative pregnant women (P = 0.024 and P < 0.001, respectively). However, there was no association found between serum selenium and other pregnancy outcomes. Conclusion: HIV-positive pregnant women had a lower mean serum selenium level compared to HIV-negative pregnant women. There was a significant association between low maternal serum selenium level and maternal anemia, as well as low birth weight, especially in HIV-positive pregnant women.


Résumé Contexte: L'infection par le virus de l'immunodéficience humaine (VIH) constitue une complication médicale majeure de la grossesse et est associée avec des issues fœto-maternelles défavorables. Cependant, la relation entre les niveaux de sélénium sérique maternel et les résultats de la grossesse aété incohérent. Objectif: Cette étude visait à déterminer la relation entre le statut maternel en sélénium sérique et la grossesse résultat chez les femmes séropositives et séronégatives dans un établissement de santé tertiaire Méthodologie: une étude transversale comparative a été menée auprès de femmes enceintes séropositives et séronégatives dans un établissement de soins de santé tertiaires à Owerri. Les participants étaient recrutés dans la salle de travail et interrogés à l'aide d'un questionnaire structuré. Cent dix femmes enceintes séropositives ont été comparativement à un nombre égal de femmes enceintes séronégatives. Elles ont été appariées pour l'âge, la parité et l'âge gestationnel. Le niveau de sélénium a été mesuré à l'aide d'un spectrophotomètre d'absorption atomique. L'hématocrite maternel (PCV) a également été évalué à recrutement. À l'accouchement, le poids à la naissance a été mesuré à l'aide d'une balance standard et documenté. Des cas de naissances prématurées, de décès périnataux, d'anomalies congénitales majeures et d'admissions néonatales ont été notés et également documentés. L'analyse statistique a été effectuée à l'aide des moyennes et des normes déviation. Le test du chi carré, le test t de Student, la régression logistique et la corrélation de Pearson ont également été utilisés. La signification statistique était considéré à P < 0,05. Résultats: Les femmes enceintes séropositives avaient une concentration sérique moyenne de sélénium significativement plus faible que avec des femmes enceintes séronégatives (64,3 ± 19,6 µg/L vs 100,1 ± 30,9 µg/L ; P < 0,001). Il y avait une association statistiquement significative entre la concentration sérique de sélénium et le poids à la naissance chez les femmes enceintes séropositives et séronégatives (P < 0,001). De la même manière, une association statistiquement significative a été observée entre le sélénium sérique et l'hématocrite maternel chez les femmes enceintes séropositives et séronégatives.femmes (P = 0,024 et P < 0,001, respectivement). Cependant, aucune association n'a été trouvée entre le sélénium sérique et d'autres grossesses. Résultats. Conclusion: les femmes enceintes séropositives avaient un taux sérique moyen de sélénium par rapport aux femmes enceintes séronégatives femmes. Il y avait une association significative entre la faible taux sérique de sélénium et anémie maternelle, ainsi que faible taux de naissance poids, en particulier chez les femmes enceintes séropositives. Mots-clés: enceinte séronégative pour le virus de l'immunodéficience humaine femmes, femmes enceintes séropositives pour le virus de l'immunodéficience humaine, taux de sélénium maternel, résultat de la grossesse.

RESUMO

Literature reports increased FDG nodal uptake in HIV-positive patients. Our aim is to identify differences in presentation and characteristics of FDG-avid lymph nodes between HIV-positive and HIV-negative locally advanced cervical cancer (LACC) patients in our clinical setting. We evaluated 250 pre-treatment 18F-FDG PET/CT imaging studies from women screened for a phase III randomised controlled trial investigating modulated electro-hyperthermia as a radiosensitiser (Ethics approval: M120477). The number of nodes; size; maximum standardised uptake value (SUVmax); symmetry; and relationship between nodal size and SUVmax uptake, were assessed by region and by HIV status. In total, 1314 nodes with a SUVmax ≥ 2.5 were visualised. Of 128(51%) HIV-positive participants, 82% were on antiretroviral therapy (ART) and 10 had a CD4 count <200 cells/µL. Overall pattern of presentation and nodal characteristics were similar between HIV-positive and -negative groups and the uniformity in presentation of the nodes draining the cervix strongly suggests these nodes may be attributed to malignancy rather than HIV infection. Novel findings: HIV infection is associated with: >four nodes visualised in the neck, symmetrical inguinal lymph nodes, increased rates of supraclavicular node visualisation; FDG-avid axillary nodes were more common, but not exclusive, in HIV-positive participants. 18F-FDG PET/CT is a reliable staging method for LACC in HIV-positive patients who are not in acute stages of HIV infection, have a CD4 count >200 cells/µL, and/or are on ART and there is a potential risk of underestimating metastatic spread by attributing increased nodal metabolic activity to HIV infection in these patients.

RESUMO

Hahnemann University Hospital has performed 120 kidney transplantations in human immunodeficiency virus (HIV)-positive individuals during the last 16 years. Our patient population represents ∼10% of the entire US population of HIV-positive kidney recipients. In our earlier years of HIV transplantation, we noted increased rejection rates, often leading to graft failure. We have established a multidisciplinary team and over the years have made substantial protocol modifications based on lessons learned. These modifications affected our approach to candidate evaluation, donor selection, perioperative immunosuppression, and posttransplantation monitoring and resulted in excellent posttransplantation outcomes, including 100% patient and graft survival at 1 year and patient and graft survival at 3 years of 100% and 96%, respectively. We present key clinical data, including a granular patient-level analysis of the associations of antiretroviral therapy regimens with long-term survival, cellular and antibody-mediated rejection rates, and the causes of allograft failures. In summary, we provide details on the evolution of our approach to HIV transplantation during the last 16 years, including strategies that may improve outcomes among HIV-positive kidney transplantation candidates throughout the United States.

RESUMO

Hazardous alcohol consumption is a common diagnosis among people living with HIV infection. The relationship between alcohol consumption and poor adherence to antiretroviral therapy has been highlighted in different studies, yet few of them performed a parallel analysis of other substance use. In Spain, alcohol consumption is frequently associated with other substance use, mainly cannabis and cocaine. The aim of this study is to assess the influence of hazardous alcohol consumption both combined with other substances (cocaine, heroin, methadone and/or cannabis) or alone on antiretroviral therapy adherence in our social environment. We performed an observational case-control study including 119 HIV+ individuals. We recruited 40 non-adherent patients, defined by less than 90% compliance according to hospital pharmacy refill data, and corroborated by the Simplified Medication Adherence Questionnaire (SMAQ) and referring professional's opinion. Control cases (n=79) were defined as those patients with similar characteristics but considered adherent according to the same parameters. Data collection took place between May 2013 and September 2015. Statistical analysis was performed using a binary logistic regression model. Our results indicate that alcohol consumption decreases adherence to antiretroviral therapy. The use of methadone represents a statistically significant increased risk of poor adherence. No significant differences were found between adherent and non-adherent groups regarding cocaine, heroin or cannabis use in this study. In summary, the detection of substance use and especially alcohol consumption in HIV+ patients can improve the effectiveness of antiretroviral therapy by identifying and treating at-risk individuals for a poor therapeutic adherence.


El consumo perjudicial de alcohol es un diagnóstico de elevada prevalencia en pacientes VIH+. Distintos estudios han destacado la influencia negativa del mismo sobre la adherencia al tratamiento antirretroviral, aunque pocos de ellos valoran además el consumo de otras sustancias. En España, el consumo de alcohol se presenta frecuentemente en situación de policonsumo, fundamentalmente de cannabis y cocaína. El objetivo es comprobar cómo influye el consumo de alcohol, asociado o no al uso de otras sustancias (cocaína, heroína, metadona y/o cannabis), en la adherencia al tratamiento antirretroviral en nuestro entorno. Se ha realizado un estudio observacional tipo casos y controles sobre una muestra de 119 individuos VIH+. Conforman los casos (n=40) sujetos no adherentes al tratamiento farmacológico según reporte de Farmacia Hospitalaria, corroborado por el Simplified Medication Adherence Questionnaire (SMAQ) y la opinión del profesional de referencia. Se consideran controles (n=79) una muestra de pacientes de características similares con buena adherencia terapéutica según los mismos métodos de valoración. La recogida de datos se hizo entre mayo 2013 y septiembre 2015. El análisis estadístico se realizó mediante regresión logística binaria. Los resultados muestran que el consumo de alcohol empeora la adherencia al tratamiento antirretroviral. El uso de metadona supone un incremento estadísticamente significativo del riesgo de no adherencia. No se han encontrado diferencias significativas entre los grupos del estudio respecto a los consumos de cocaína, heroína o cannabis. Por tanto, la detección del consumo de sustancias, especialmente de alcohol, y su abordaje en pacientes VIH+ puede repercutir positivamente en el cumplimiento terapéutico, en beneficio de una mayor efectividad de la terapia antirretroviral.

RESUMO

CONTEXT: Women who are living with HIV use IUDs at a lower rate than the general population, and it is unclear whether health care providers' misconceptions about IUD safety contribute to this disparity. METHODS: A 2013-2014 nationwide survey of 1,998 U.S. family planning providers assessed perceptions of IUD safety for women with HIV or other medical conditions. Multivariable logistic regression was used to examine associations between provider characteristics and whether individuals believed IUDs were safe for HIV-positive women. Data from public-sector providers and office-based physicians were analyzed separately. RESULTS: Seven in 10 providers considered IUDs safe for women with HIV, and there were no differences by provider type. Among public-sector providers, some of the characteristics associated with believing that IUDs were unsafe for seropositive women were working at a clinic without Title X funding (odds ratio, 1.5), not being trained in IUD insertion (2.1) and not using the U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) for clinical guidance (1.8). Office-based physicians who did not use the guidelines also had an increased likelihood of believing that IUDs were unsafe for women with HIV (2.9), and physicians who had completed training 25 or more years ago were more likely than those who had done so less than five years ago to consider IUDs unsafe (3.3). CONCLUSIONS: Greater use of evidence-based contraceptive guidance such as the U.S. MEC may help inform provider perceptions of IUD safety and hence contribute to increased contraceptive choice for women with HIV.

RESUMO

Simple effective tools to monitor the long treatment of tuberculosis (TB) are lacking. Easily measured host derived biomarkers have been identified but need to be validated in larger studies and different population groups. Here we investigate the early response in IP-10 levels (between day 0 and day 7 of TB therapy) to identify bacteriological status at diagnosis among 127 HIV-infected patients starting TB treatment. All participants were then classified as responding or not responding to treatment blindly using a previously described IP-10 kinetic algorithm. There were 77 bacteriologically confirmed cases and 41 Xpert MTB/RIF® and culture negative cases. Most participants had a measurable decline in IP-10 during the first 7 days of therapy. Bacteriologically confirmed cases were more likely to have high IP-10 levels at D0 and had a steeper decline than clinically diagnosed cases (mean decline difference 2231 pg/dl, 95% CI: 897-3566, p = 0.0013). Bacteriologically confirmed cases were more likely to have a measurable decline in IP-10 at day 7 than clinically diagnosed cases (48/77 (62.3%) vs 13/41 (31.7%), p < 0.001). This study confirms the association between a decrease in IP-10 levels during the first week of treatment and a bacteriological confirmation at diagnosis in a large cohort of HIV positive patients.

RESUMO

PURPOSE: To evaluate efficacy and safety of 20 000 IU cholecalciferol weekly in HIV-infected patients. METHODS: Longitudinal data for 243 HIV-infected patients with paired 25-OH-vitamin D3 values for the same month in 2 consecutive years were stratified by the initiation of supplementation in this retrospective study. RESULTS: After 1 year of administration of cholecalciferol 20 000 IU weekly, about 78% of patients with initial vitamin D level <20 µg/L achieved vitamin D levels >20 µg/L and 42% achieved levels >30 µg/L. Supplemented patients with baseline vitamin D levels <20 µg/L showed a significant risk reduction for hypocalcemia ( P = .006; risk difference: 20.8%) and a significantly lower increase in alkaline phosphatase (AP) compared to those in the nonsubstituted group. CONCLUSION: The dose of 20 000 IU of cholecalciferol once weekly was found to be safe and effective. Normalization of vitamin D levels within 1 year was observed in 42% to 75% of the patients.
