RESUMEN

BACKGROUND: Syphilis is an infection caused by the bacteria Treponema pallidum. It is mainly transmitted through oral, vaginal and anal sex, in pregnancy and through blood transfusion. Syphilis develops in primary, secondary, latent and tertiary stages and presents with different clinical features at each stage. Infected patients can remain asymptomatic for several years and, without treatment, can, in extreme cases, manifest as damage in several organs and tissues, including the brain, nervous tissue, eyes, ear and soft tissues. In countries with a high human immunodeficiency virus (HIV) burden, syphilis increases the risk of HIV infections. We report the case of a young HIV-positive black woman who presented with alopecia and hypopigmentation as features of secondary syphilis. CASE PRESENTATION: A virologically suppressed 29-year-old woman on Anti-retroviral Therapy (ART) presented with a short history of generalized hair loss associated with a non-itchy maculopapular rash and skin depigmentation on the feet. Limited laboratory testing confirmed a diagnosis of secondary syphilis. She was treated with Benzathine Penicillin 2.4MU. After receiving three doses of the recommended treatment, the presenting features cleared, and the patient recovered fully. CONCLUSION: This case demonstrates the importance of a high index of clinical suspicion and testing for syphilis in patients presenting with atypical clinical features of secondary syphilis, such as hair loss and hypopigmentation. It also highlights the challenges in diagnosing and clinically managing syphilis in a resource-limited setting.

RESUMEN

We conducted secondary data analysis using a biobehavioral survey dataset of 1538 MSM from Zimbabwe. Survey participants were screened for the four symptoms suggestive of tuberculosis infection using the WHO TB screening algorithm. Results: All participants experienced at least one symptom suggestive of tuberculosis. 40% of HIV-positive MSM reported having had a cough in the last month and 13% of them experienced unexpected weight loss. The prevalence of experiencing any of the four TB symptoms amongst HIV-positive MSM was 23%. Contribution There is an urgent need for active TB case finding and treatment amongst HIV-positive MSM in Zimbabwe. Clinicians will need to ensure that MSM who need TB testing receive it timeously.

RESUMEN

High-fat diet (HFD) is well known to impact various aspects of gut health and has been associated with many diseases and inflammation. However, the impact of HFD feeding on HIV-1 rectal transmission has not yet been well addressed. With an increasing threat of HIV-1 infection in men who have sex with men (MSM), where the rectal route is the primary mode of infection, it is imperative to understand the impact of HFD on gut microbiota and inflammation and consequently, its effect on HIV-1 rectal transmission. Here, we utilized our double humanized bone marrow, liver, thymus (dHu-BLT) mouse model to assess the impact of HFD feeding on the host's susceptibility to HIV-1 rectal transmission. We found that feeding an HFD successfully altered the gut microbial composition within 3 weeks in the dHu-BLT mouse model. In addition, levels of inflammatory mediators, specifically IL-12p70, IP-10, ICAM-1, and fecal calprotectin, were significantly higher in HFD-fed mice compared to control mice on a regular chow diet. We also observed that significantly different inflammatory markers (IL-12p70 and ICAM-1) were negatively correlated with the number of observed ASVs, Shannon diversity, and Faith's diversity in the HFD-fed group. Notably, when repeatedly challenged with a low dose of HIV-1 via a rectal route, mice receiving an HFD were significantly more susceptible to HIV-1 rectal infection than control mice. Together, these results underscore the impact of HFD feeding on the gut microbiota and inflammation and suggest the significance of diet-induced gut microbial dysbiosis and inflammation in promoting viral infection.IMPORTANCEHFD induces gut microbial dysbiosis and inflammation and has been associated with many infections and disease progression; however, its impact on HIV-1 rectal transmission is largely unknown. Given the increasing threat of HIV-1 incidence in men who have sex with men (MSM), it has become crucial to comprehend the impact of factors associated with gut health, like HFD consumption, on host susceptibility to HIV-1 rectal transmission. This is particularly important since anal intercourse remains the primary mode of HIV transmission within the MSM group. In this study, utilizing our unique mouse model, featuring both the human immune system and gut microbiota, we showed that HFD feeding led to gut microbial dysbiosis, induced inflammation, and increased HIV-1 rectal transmission. Collectively, our study highlights the significant impact of HFD on gut microbiota and inflammation and suggests an HFD consumption as a potential risk factor for promoting HIV-1 rectal susceptibility.

RESUMEN

The activities of HIV-1 in the central nervous system (CNS) are responsible for a dysregulated neuroinflammatory response and the subsequent development of HIV-associated neurocognitive disorders (HAND). The use of post-mortem human brain tissue is pivotal for studying the neuroimmune mechanisms of CNS HIV infection. To date, numerous studies have investigated HIV-1-induced neuroinflammation in post-mortem brain tissue. However, from the commonly investigated studies in this line of research, it is not clear which neuroinflammatory markers are consistently associated with HIV neurocognitive impairment (NCI) and neuropathology (i.e., HIV-encephalitis, HIVE). Therefore, we conducted a systematic review of the association between neuroinflammation and NCI/HIVE from studies investigating post-mortem brain tissue. Our aim was to synthesise the published data to date to provide commentary on the most noteworthy markers that are associated with NCI/HIVE. PubMed, Scopus, and Web of Science databases were searched using a search protocol designed specifically for this study. Sixty-one studies were included that investigated the levels of inflammatory markers based on their gene and protein expression in association with NCI/HIVE. The findings revealed that the (1) transcript expressions of IL-1ß and TNF-α were consistently associated with NCI/HIVE, whereas CCL2 and IL-6 were commonly not associated with NCI/HIVE, (2) protein expressions of CD14, CD16, CD68, Iba-1, IL-1ß and TNF-α were consistently associated with NCI/HIVE, while CD45, GFAP, HLA-DR, IL-1 and IL-6 were commonly not associated with NCI/HIVE, and (3) gene and protein expressions of CNS IL-1ß and TNF-α were consistently associated with NCI/HIVE, while IL-6 was consistently not associated with NCI/HIVE. These markers highlight the commonly investigated markers in this line of research and elucidates the neuroinflammatory mechanisms in the HIV-1 brain that are involved in the pathophysiology of NCI/HIVE. These markers and related pathways should be investigated for the development of improved diagnostics, prognostics, and therapeutics of HAND.

RESUMEN

OBJECTIVE: HIV-1 invades the brain within days post-transmission. This study quantitated cerebrospinal fluid (CSF) white blood cell count (WBC) and investigated whether it associated with plasma and CSF HIV-1 RNA during untreated acute HIV infection (AHI). DESIGN: Seventy participants underwent lumbar puncture during Fiebig stages I-V AHI. METHOD: WBC and HIV-1 RNA with a lower limit of quantification (LLQ) of 80 copies/ml were measured in CSF. RESULTS: Sixty-nine (99%) participants were men, with a median age of 26. Their blood CD4 + and CD8 + T-cell counts were 335 [interquartile range (IQR) 247-553) and 540 (IQR 357-802) cells/µl, respectively. Forty-five (64%) were in Fiebig stages III-V whereas 25 (36%) were in Feibig stages I-II. Fifty-two (74%) experienced acute retroviral syndrome. Median plasma and CSF HIV-1 RNA were 6.10 (IQR 5.15-6.78) and 3.15 (IQR 1.90-4.11) log 10 copies/ml, respectively. Sixteen (23%) CSF samples had HIV-1 RNA below LLQ. Median CSF WBC was 2.5 (IQR 1-8) cells/µl. CSF pleocytosis (WBC >5) was observed in 33% and was only present in CSF samples with detectable HIV-1 RNA. The frequencies of CSF pleocytosis during Fiebig stages III-V and among CSF samples of higher viral load (>1000 copies/ml) were 42 and 45%, respectively. Pleocytosis independently associated with CSF HIV-1 RNA in multivariate analysis [adjusted coefficient: 0.79, 95% confidence interval (CI) 0.41-1.14), P  < 0.001] and a lower plasma to CSF HIV-1 RNA ratio ( P  < 0.001). CONCLUSION: CSF pleocytosis was present in one-third of participants with AHI. It associated with higher CSF HIV-1 RNA and a lower plasma to CSF HIV-1 RNA ratio, suggesting a potential association with HIV-1 neuroinvasion.

RESUMEN

Both HIV-1 infection and smoking may contribute to the development of ageing-related manifestations affecting the prognosis of people living with HIV, but it is unclear whether HIV and smoking exert their effects independently or interact by potentiating each other. We conducted a cross-sectional study in 192 people living with HIV aged- and gender-matched with 192 HIV-uninfected controls, assessing the relative effect of HIV-1/smoking status on lung function (FEV1), bone mineral density (BMD), appendicular skeletal muscle mass index (ASMI), aortic pulse-wave velocity (PWV), insulin resistance (HOMA-IR) and renal function. In both unadjusted and adjusted analyses, FEV1, BMD and ASMI significantly differed according to smoking/HIV status, with the worst parameters found in HIV-1 infected patients currently smoking, and BMD and ASMI decreased to a lesser extent in HIV-1 infected patients formerly smoking (> 10 pack-years). Values in people living with HIV with < 10 pack-years exposure were of similar magnitude to those from controls. Regarding PWV, HOMA-R and eGFR, no significant differences were found, with the exception of eGFR values which were globally lower in HIV-1 infected patients. In conclusion HIV infection and smoking acted synergistically and were associated with a wasting phenotype combining muscle mass and bone mineral reduction.Clinical Trial Registration (registrar, website, and registration number), where applicable: CPP 10-023, 09-027, 10-034.

RESUMEN

BACKGROUND: Women who inject drugs in Ukraine are disproportionately burdened by HIV. To help address the needs of this population, a greater understanding of how interventions may uniquely benefit women who inject drugs is needed. METHODS: Data come from a randomized controlled trial of a social network intervention targeting people who inject drugs in Ukraine (N = 1195). Indexes, plus two of their injection network members, received HIV testing and counseling (control arm) or HIV testing and counseling plus a social network intervention (intervention arm), in which indexes were trained to influence network members' risk behaviors. We used Cox regressions with interaction terms to assess differences in time to HIV seroconversion between arms by network gender composition and gender of the index. For significant interaction terms, we calculated simple effects, generated survival functions using Kaplan-Meier methods, and compared survival curves using log-rank tests. RESULTS: At 12 months, there were 45 seroconversions among women (40.0 [28.3, 51.7] per 100 person years) and 111 among men (28.4 [23.1, 33.6] per 100 person years) in the control arm; there were 27 seroconversions among women (17.1 [10.7, 23.6] per 100 person years) and 77 among men (18.7 [14.5, 22.9] per 100 person years) in the intervention arm. Network gender composition (but not gender of the index) moderated the intervention effect on HIV incidence (p < 0.05). Specifically, the intervention appeared to be even more protective against HIV acquisition as female gender composition increased. In the intervention arm, the HIV seroconversion hazard rate was 44% lower with 1 network female; 61% lower with 2 network females; and 72% lower with 3 network females. CONCLUSIONS: A greater number of women in an injection network, coupled with the provision of risk-reduction strategies, is associated with HIV risk-mitigation, though the mechanisms through which this occurs remain unclear. Findings can support new research and practice directions that prioritize women who inject drugs and more thoughtfully support their health and wellbeing.

RESUMEN

PURPOSE: We aimed to study the ocular manifestations in human immunodeficiency virus (HIV)-infected patients and the correlation of posterior segment lesions with CD4+ counts. METHODS: This hospital-based, cross-sectional study enrolled HIV-positive patients attending the ophthalmology department of a tertiary care hospital in Eastern India. Complete demographic information was obtained for each patient. Comprehensive ophthalmic evaluation was done in each case. RESULTS: A total of 184 HIV-positive patients were enrolled in the study. Ocular manifestations were detected in 62 cases. The prevalence of ocular manifestations in the present study was 33.69%. Mean age of patients included in the study was 34.8 ± 10.77 years. Prevalence of ocular manifestations was highest in the age group of 30-39 years (41.93%). Highest prevalence of ocular manifestations was noted in patients with low level of education and poor socioeconomic status. Sexual transmission was the major route of HIV transmission (in 92% of cases). Posterior segment lesions were seen in 69.35% of cases. HIV retinopathy was the most common posterior segment manifestation noted in 25 eyes. Significant positive correlation was noted between severities of posterior segment findings and CD4+ counts, which we found to increase with decrease in CD4+ counts (P < 0.001). CONCLUSION: Detailed ophthalmic evaluation including fundus examination is must in all cases of HIV/acquired immunodeficiency syndrome (AIDS) patients as it may help in early diagnosis, treatment, and prevention of sight-threatening complications due to opportunistic infections.

RESUMEN

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.

RESUMEN

BACKGROUND: Adjunctive glucocorticoids are widely used to treat human immunodeficiency virus (HIV)-associated tuberculous meningitis despite limited data supporting their safety and efficacy. METHODS: We conducted a double-blind, randomized, placebo-controlled trial involving HIV-positive adults (≥18 years of age) with tuberculous meningitis in Vietnam and Indonesia. Participants were randomly assigned to receive a 6-to-8-week tapering course of either dexamethasone or placebo in addition to 12 months of antituberculosis chemotherapy. The primary end point was death from any cause during the 12 months after randomization. RESULTS: A total of 520 adults were randomly assigned to receive either dexamethasone (263 participants) or placebo (257 participants). The median age was 36 years; 255 of 520 participants (49.0%) had never received antiretroviral therapy, and 251 of 484 participants (51.9%) with available data had a baseline CD4 count of 50 cells per cubic millimeter or less. Six participants withdrew from the trial, and five were lost to follow-up. During the 12 months of follow-up, death occurred in 116 of 263 participants (44.1%) in the dexamethasone group and in 126 of 257 participants (49.0%) in the placebo group (hazard ratio, 0.85; 95% confidence interval, 0.66 to 1.10; P = 0.22). Prespecified analyses did not reveal a subgroup that clearly benefited from dexamethasone. The incidence of secondary end-point events, including cases of immune reconstitution inflammatory syndrome during the first 6 months, was similar in the two trial groups. The numbers of participants with at least one serious adverse event were similar in the dexamethasone group (192 of 263 participants [73.0%]) and the placebo group (194 of 257 participants [75.5%]) (P = 0.52). CONCLUSIONS: Among HIV-positive adults with tuberculous meningitis, adjunctive dexamethasone, as compared with placebo, did not confer a benefit with respect to survival or any secondary end point.

RESUMEN

INTRODUCTION: The success of antiretroviral therapy (ART) has changed HIV from a deadly to a chronic infection, thus increasing the transitioning from infancy toward adulthood. However, the virostatic nature of antiretrovirals maintains viruses in sanctuaries, with reactivation potentials. Because current ARTs are very limited for children, the emergence of new HIV epidemics driven by HIV drug-resistance mutations is favoured. Our systematic review aims to estimate the global burden of archived drug-resistance mutations (ADRMs) and the size of reservoir (HIV-1 DNA load), and their associated factors in children and adolescents. METHODS AND ANALYSIS: Papers from the PubMed/MEDLINE, Google Scholar, ScienceDirect, African Journals Online and Academic Medical Education Databases will be systematically identified using the keywords: "HIV-1 reservoirs", "viral reservoirs", "HIV-1 DNA", infants, adolescents, child and children, linked by the following Boolean operators: 'OR' and 'AND'. Randomised and non-randomised trials, cohort studies and cross-sectional studies published in French or English from January 2002 will be included, while case reports, letters, comments, reviews, systematic reviews and meta-analyses, and editorials will be excluded. All studies describing data on ADRMs, HIV-1 DNA load and/or immunological markers among children/adolescents will be eligible. A random-effects model will be used to calculate the pooled prevalence of ADRMs. Data will be reported according to type of viral reservoir (peripheral blood mononuclear cells, CD4 cells), geographical location (country/continent), ethnicity/race, age (infants vs adolescents), gender, HIV-1 clades, ART exposure (naïve vs treated, drug class, type of regimen, age at ART initiation and treatment duration), WHO clinical staging (I, II, III, IV), immune status (immune compromised vs immune competent) and virological response (viraemic vs non-viraemic). Multivariate logistic regression will be performed to determine predictors of HIV reservoir profile in paediatric populations. The primary outcome will be to assess the genotypical and quantitative profile of HIV reservoirs, while the secondary outcomes will be to identify factors associated with ADRMs and reservoir size in paediatric populations. ETHICS AND DISSEMINATION: Ethical approval is not applicable for this study as it will be based on published data. Results will be disseminated via a peer-reviewed scientific journal and relevant conferences. PROSPERO REGISTRATION NUMBER: CRD42022327625.

RESUMEN

BACKGROUND: Despite the human immunodeficiency virus (HIV) being the most common comorbidity in South African surgical patients, its impact on appendicitis has not been well-described. We aimed to determine HIV status' influence on patients' presentation, assessment, management and outcomes with acute appendicitis. METHODS: The retrospective chart review included all patients aged 12 years and older who were HIV-positive or HIV-negative and presented with acute appendicitis between 1 January 2013 and 31 December 2019. The primary outcome measure was survival to discharge. Secondary outcomes included analysis of the presentation (vital signs), assessment (biochemical, inflammatory markers) and management (intraoperative anatomical severity grading, length of hospital stay). RESULTS: Of the 1096 patients with appendicitis, 196 (17.9%) were HIV-positive, and CD4 counts were available for 159. The median age was 23 years, with the HIV-positive patients being older and HIV-negative group having more males (58.7%). While the HIV-positive patients had a longer median length of hospital stay, there was no statistically significant difference in the two groups' incidence of high-grade appendicitis (p = 0.670). The HIV-positive patients had a higher median shock index (OR 7.65; 95% [CI 2.042-28.64]) than their HIV-negative counterparts. HIV-positivity had a significant association with mortality (OR 9.56; 95% CI [1.68-179.39]), and of the seven HIV-positive patients who died, 66.7% (n = 4) had a CD4 < 200 cells/mm3 (OR 8.6; 95% CI [1.6-63.9]). CONCLUSION: HIV-positive patients, those with CD4 < 200 cells/mm3 or not on ART, have increased mortality risk and may benefit from increased perioperative surveillance. Patients with an unknown HIV status in a high-prevalence population should be offered HIV testing to risk stratify more accurately.

RESUMEN

BACKGROUND: We identified whether maternal human immunodeficiency virus (HIV) infection during pregnancy affects transplacental transfer of Kaposi sarcoma-associated herpesvirus (KSHV)-specific antibodies and subsequent infant infection. METHODS: We followed pregnant Kenyan women through delivery and their infants until age 2 years. Children were classified as HIV-exposed uninfected (HEU) or HIV-unexposed uninfected (HUU) based on maternal HIV status. Maternal venous and cord blood at delivery and child venous blood every 6 months were tested for antibodies to 20 KSHV antigens by multiplex bead-based immunoassay. Multiple comparisons were adjusted using false discovery rate (FDR). RESULTS: Maternal HIV infection was significantly associated with decreased transplacental transfer of antibodies against all KSHV antigens and lower cord blood levels for 8 antigens at FDR P < .10. Neither birth to 6-month antibody level changes nor 6-month levels differed in HEU and HUU, except for ORF50. By age 24 months, 74% of children KSHV seroconverted but HEU and HUU did not differ in time to seroconversion nor 2-year seropositivity after adjustment for child malaria infection. CONCLUSIONS: Maternal HIV infection reduced a child's initial KSHV antibody levels but did not affect age of infection. Regardless of HIV exposure in utero, KSHV seroconversion in Kenyan children occurred early; associated factors must be identified.

RESUMEN

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.

RESUMEN

BACKGROUND: Psychosocial challenges among human immunodeficiency virus (HIV)-positive patients may promote substance use disorders. This study explored the relationship between conjoint tobacco and alcohol use and depression symptoms among HIV positive patients in Sedibeng District, South Africa. METHODS: In a cross-sectional study of 404 participants, a questionnaire collected information on sociodemography, tobacco and alcohol use and depression symptoms. Outcome measures included the prevalence of conjoint tobacco and alcohol use and its association with positive screen for depression. RESULTS: The mean participant age was 43.2 years. Most completed secondary school (62.9%), were black (99.0%), female (65.8%), unemployed (53.6%) and on antiretroviral therapy (ART) for 1 year (97.8%). Current tobacco use was reported by 23.3% (n = 94) participants with most smoking cigarette (73.7%) and having low nicotine dependence (75.5%). Current alcohol use was reported by 43.6% (n = 176) participants, and 36.9% were categorised as harmful users. Only 7.7% (n = 31) participants screened positive for depression; the prevalence of conjoint tobacco and alcohol use was 19.6% (n = 79) and this was not associated with depression (p = 0.438). Harmful alcohol users were more than five times likely to report conjoint tobacco and alcohol use (p = 0.000), but women were less likely to report it (p = 0.000). CONCLUSION: Conjoint tobacco and alcohol use is common among patients with HIV infection. Although not associated with positive screen for depression, its relationship with harmful alcohol use reiterates the need for an integrated tobacco and alcohol use screening and treatment strategy in the HIV treatment programme in primary care.Contribution: To the authors best knowledge, this study is the first published study that explored the relationship between conjoint tobacco and alcohol use, and depression among HIV-positive patients in the South African primary care settings.

RESUMEN

BACKGROUND: Cervical cancer is the leading cause of disability and mortality among women in Africa. Despite a significant correlation between HIV/AIDS and cervical cancer, there is unacceptably low coverage of the uptake of cervical cancer screening among human immunodeficiency virus-positive women in Sub-Saharan Africa. Individual primary studies are limited in explaining the patterns of uptake of cervical cancer screening. This review therefore considers the uptake of cervical cancer screening and its barriers among human immunodeficiency virus-positive women in Sub-Saharan Africa. METHODS: We systematically searched articles published until December 31, 2019, from the PubMed, Cochrane Library, POP LINE, Google Scholar, African Journals Online and JURN databases. The quality of the included articles was assessed by using the Newcastle‒Ottawa Scale, and the coverage of uptake of cervical cancer screening was pooled after checking for heterogeneity and publication bias. The random effect model was used, and subgroup analysis estimates were performed by country. RESULTS: Twenty-one studies comprising 20,672 human immunodeficiency virus-positive women were included. Applying a random effect model, the overall cervical cancer screening uptake among this group of women in Sub-Saharan Africa was estimated to be 30% (95% CI: 19, 41, I2 = 100%). The main barriers to uptake of cervical screening include poor knowledge about cervical cancer and screening, low risk perception of cervical cancer, fear of test result and fear of screening as painful, lack of access to screening services, high cost of screening service, and poor partner attitude and acceptance of the service. The perception of an additional burden of having a cervical cancer diagnosis was found to be a unique barrier among this population of women. CONCLUSION: The unacceptably low coverage of uptake of cervical cancer screening would indicate that the need to scale up the opportunities to these groups of women as well. This review revealed that in addition to structural and health care system barriers, sociocultural and personal barriers are powerful barriers in HIV-positive women. For these cohorts of population, a particular obstacle was discovered to be perception of an additional burden of having cervical cancer.

RESUMEN

BACKGROUND: High-risk HPV is considered a major risk factor for the development of cervical cancer, the most common malignancy among women in Uganda. However, there is a paucity of updated epidemiological data on the extent of the burden and factors associated with hr-HPV infection among women of reproductive age. The aim of this study was to determine the prevalence and genotype distribution of hr-HPV and associated factors among women of reproductive age attending a rural teaching hospital in western Uganda. METHODS: We conducted a cross-sectional study from April to June 2022. A total of 216 women of reproductive age attending the gynecological outpatient clinic were consecutively enrolled. Interviewer-administered questionnaires were used to collect participant characteristics, cervical specimens were collected by clinicians, and molecular HPV testing was performed using the Cepheid Xpert HPV DNA test. Descriptive statistics followed by binary logistic regression were conducted using SPSS version 22. RESULTS: The prevalence of hr-HPV was 16.67%. Other hr-HPV types other than HPV 16 and 18 were predominant, with a prevalence of 10.6%; HPV 18/45 (2.31%), HPV 16 (0.46%), and 3.24% of the study participants had more than one hr-HPV genotype. On multivariate logistic regression, an HIV-positive status (aOR = 7.06, CI: 2.77-10.65, p = 0.007), having 3 or more sexual partners in life (aOR = 15.67, CI: 3.77-26.14, p = 0.008) and having an ongoing abnormal vaginal discharge (aOR = 5.37, CI: 2.51-11.49, p = 0.002) were found to be independently associated with hr-HPV infection. CONCLUSIONS AND RECOMMENDATIONS: The magnitude of hr-HPV is still high compared to the global prevalence. HIV-positive women and those in multiple sexual relationships should be prioritized in cervical cancer screening programs. The presence of abnormal vaginal discharge in gynecology clinics should prompt HPV testing.

RESUMEN

BACKGROUND: Herpes simplex virus type 2 (HSV-2) is an incurable sexually transmitted infection associated with increased risk of acquiring and transmitting human immunodeficiency virus (HIV). HSV-2 is highly prevalent in sub-Saharan Africa, but population-level estimates of incidence are sparse. METHODS: We measured HSV-2 prevalence from cross-sectional serological data among adults aged 18-49 years in 2 south-central Uganda communities (fishing, inland). We identified risk factors for seropositivity, then inferred age patterns of HSV-2 with a Bayesian catalytic model. RESULTS: HSV-2 prevalence was 53.6% (n = 975/1819; 95% confidence interval, 51.3%-55.9%). Prevalence increased with age, was higher in the fishing community, and among women, reaching 93.6% (95% credible interval, 90.2%-96.6%) by age 49 years. Factors associated with HSV-2 seropositivity included more lifetime sexual partners, HIV positive status, and lower education. HSV-2 incidence peakied at age 18 years for women and 19-20 years for men. HIV prevalence was up to 10-fold higher in HSV-2-positive individuals. CONCLUSIONS: HSV-2 prevalence and incidence were extremely high, with most infections occurring in late adolescence. Interventions against HSV-2, such as future vaccines or therapeutics, must target young populations. Remarkably higher HIV prevalence among HSV-2-positive individuals underscores this population as a priority for HIV prevention.

RESUMEN

BACKGROUND: There has been a significant increase in methamphetamine use among persons who use drugs in Vietnam in the last 5-10 years. We examined the degree to which adherence to antiretroviral therapy (ART) mediates the relationship between recent methamphetamine use and unsuppressed HIV viral load among people who inject drugs (PWID) in Hai Phong, Vietnam. METHODS: We recruited PWID from October 2016-October 2018 and enrolled HIV positive PWID into a cohort, with up to three years of total follow-up. We assessed relationships among recent methamphetamine use frequency, ART adherence and unsuppressed HIV viral load. Mediation analysis was used to estimate the total and natural direct effects of recent methamphetamine use on unsuppressed HIV viral load and the indirect effect proportion. RESULTS: We enrolled 792 HIV seropositive PWID into the cohort; approximately 75.9% reported high/perfect ART adherence at baseline and 81.3% were virally suppressed. In mediation analysis, the total effect for the association between methamphetamine use and unsuppressed HIV viral load (1000 copies/mL) was 3.94 (95% CI: 1.95, 7.96); the natural direct effect was 2.14 (95% CI: 1.29, 3.55); the proportion mediated by self-reported ART adherence was 0.444. Similar results were found when examining lower unsuppressed HIV viral load cutpoints of 250 copies/mL and 500 copies/mL. CONCLUSIONS: Methamphetamine use is associated with unsuppressed HIV viral load among PWID despite high levels of ART adherence. Further research is needed to better understand these relationships, with emphasis on potential biological pathways that may interact with ART.
