RESUMO

BACKGROUND: Sexual problems are rarely addressed in human immunodeficiency virus (HIV) management, even though overt sexual dysfunctions are more prevalent in people living with HIV. This study aimed to ascertain the prevalence of erectile dysfunction (ED) among HIVinfected men in a stable clinical state, examine the relationship between antiretroviral therapy (ART) exposure and sexual dysfunction, and identify the associated risk factors. METHOD: This cross-sectional study recruited HIV-positive males who visited the Voluntary Counseling and Testing (VCT) center of Imam Khomeini Hospital (Tehran) in 2020. The International Index of Erectile Function (IIEF) questionnaire was used to evaluate the ED in participants. Sociodemographic and clinical data were also collected. RESULTS: Of 65 patients who participated in this study, 27.7% had ED. The mean age of participants with and without ED was 39.4±11.5 and 40.4±7.6 years old, respectively. No significant difference was observed between patients with and without ED concerning the sociodemographic status and the use of ART drugs. CONCLUSION: The prevalence of ED is relatively high among men living with HIV. Future research is recommended among HIV-positive males to identify the underlying causes and explore the potential impact that associated psychological distress could have on sexual dysfunction.

RESUMO

Background: Human immunodeficiency virus (HIV)-positive patients with anal condyloma acuminata (CA) present an increased risk of anal cancer progression associated with oncogenic human papillomavirus (HPV) infection. It is essential to explore determinants of anal infection by oncogenic HPV among HIV-positive patients with CA. Methods: A retrospective cohort study was performed in HIV-positive patients with CA between January 2019 to October 2021 in Shenzhen, Southeast China. Exfoliated cells were collected from CA lesions and the anal canal of HPV genotypes detected by fluorescence PCR. Unconditional logistic regression analysis was used to probe associations of independent variables with oncogenic HPV infection. Results: Among HIV-positive patients with CA, the most prevalent oncogenic genotypes were HPV52 (29.43%), HPV16 (28.93%), HPV59 (19.20%), and HPV18 (15.96%). Risk of oncogenic HPV infection increased with age at enrollment (COR: 1.04, 95% CI: 1.01-1.07, p = 0.022). In the multivariable analysis, age ≥ 35 years (AOR: 2.56, 95% CI: 1.20-5.70, p = 0.02) and history of syphilis (AOR: 3.46, 95% CI: 1.90-6.79, p < 0.01) were independent risk factors statistically associated with oncogenic HPV infection. History of syphilis (AOR: 1.72, 95% CI: 1.08-2.73, p < 0.02) was also an independent risk factor statistically associated with HPV16 or HPV18 infection. Conclusion: In clinical practice, HIV-positive CA patients aged ≥35 years or with a history of syphilis should carry out HR-HPV testing and even anal cancer-related examinations to prevent the occurrence of anal cancer.

RESUMO

BACKGROUND: Due to the restricted availability of health services in Thailand, there are still some transgender women (TGW) who do not have access to HIV counseling and testing. Telehealth, which is accessible to individuals who are reluctant to undergo face-to-face interviewing, played an especially important role during the COVID-19 epidemic. The objectives of this study are to compare the characteristics, pattern of accessing HIV testing, and the HIV-positive rates of TGW between the face-to-face and telemedicine services. METHODS: We conducted a cross-sectional study to compare the access to HIV testing and the HIV-positive rates among TGW via face-to-face service and telemedicine services and examined the influence of potential associated factors on the risk of being HIV-positive. RESULTS: Of the 637 TGW participants, 26 (4.1%) were HIV-positive. Accessing the telemedicine service increased in the third and fourth COVID-19 waves (28.1% in the first and second vs. 71.9% in the third and fourth). There was no difference in the risk of being HIV-positive between the types of service. Having sex work experience (adjusted odds ratio (aOR) = 5.92; 95% confidence interval (CI): 1.57-22.30) and either never having been or tested more than 1 year ago were independently significantly associated with a higher risk of being HIV-positive (aOR = 4.05; 95% CI: 1.11-14.77). CONCLUSION: The telemedicine service became more popular among TGW during the COVID-19 pandemic and was not related to a higher risk of being HIV-positive. Moreover, it proved to be an effective alternative channel to access HIV testing, especially for intravenous drug users. Sex work experience and irregular HIV testing are key risk factors for HIV infection in TGW seeking either the telemedicine or face-to-face service.

RESUMO

BACKGROUND: Multiple HIV outbreaks have been recorded among people who inject drugs (PWID) since 2010. During an intervention for PWID in 2019-2021 in Thessaloniki, Greece, an increasing number of HIV cases was documented. Here, we provide an analysis of this new outbreak. METHODS: ALEXANDROS was a community-based program and participation included interviewing, rapid HIV/HCV tests, counselling and linkage to care. PWID were recruited through Respondent-Driven Sampling (RDS) in five sampling rounds. Crude and RDS-weighted HIV prevalence estimates were obtained. HIV incidence was estimated from data on 380 initially seronegative PWID with at least two tests. Multivariable Cox proportional hazards model was used to assess risk factors for HIV seroconversion. RESULTS: In total, 1,101 PWID were recruited. At first participation, 53.7% were current PWID, 20.1% homeless, 20.3% on opioid substitution treatment and 4.8% had received syringes in the past 12 months. HIV prevalence (95% CI) was 7.0% (5.6-8.7%) and an increasing trend was observed over 2019-2021 (p = 0.002). Two-thirds of the cases (67.5%) were new diagnoses. HIV incidence was 7.0 new infections/100 person-years (95% CI:4.8-10.2). Homelessness in the past 12 months (HR:2.68; 95% CI:1.24-5.81) and receptive syringe sharing (HR:3.86; 95% CI:1.75-8.51) were independently associated with increased risk of seroconversion. By the end of the program, 67.3% of the newly diagnosed cases initiated antiretroviral treatment. CONCLUSIONS: A new HIV outbreak among PWID was documented in Greece during the COVID-19 pandemic with homelessness and syringe sharing being associated with increased risk of HIV acquisition. Peer-driven programs targeting the population of high-risk underserved PWID can be used to early identify emerging outbreaks and to improve linkage to HIV care.

RESUMO

BACKGROUND: The frequency of new HIV infections among female sex workers in sub-Saharan Africa is poorly understood. We used routinely collected data that enable unique identification of repeat HIV testers to assess temporal trends in seroconversion and identify associated risk factors for female sex workers accessing Sisters with a Voice, Zimbabwe's national sex worker programme. METHODS: We pooled HIV testing data gathered between Sept 15, 2009, and Dec 31, 2019, from 36 Sisters programme sites in Zimbabwe. We included female sex workers aged 16 years or older with an HIV-negative test and at least one subsequent programme test. We calculated HIV seroconversion rates (using the midpoint between the HIV-positive test and the last negative test as the seroconversion date) and estimated rate ratios to compare 2-year periods by using Poisson regression, with robust SEs to account for clustering by site and adjusting for age and testing frequency to assess temporal trends. We did sensitivity analyses to explore assumptions about seroconversion dates and the effects of variation in follow-up time on our conclusions. FINDINGS: Our analysis included data for 6665 female sex workers, 441 (7%) of whom seroconverted. The overall seroconversion rate was 3·8 (95% CI 3·4-4·2) per 100 person-years at risk. Seroconversion rates fell with time since first negative HIV test. After adjustment, there was evidence of a decrease in seroconversion rates from 2009 to 2019 (p=0·0053). In adjusted analyses, being younger than 25 years, and having a sexually transmitted infection diagnosis at a previous visit, were significantly associated with increased seroconversion rates. Our findings were mostly robust to sensitivity analyses, but when 1 month before an HIV-positive test was used as the seroconversion date, seroconversion rates no longer fell with time. INTERPRETATION: We identified high rates of seroconversion shortly after linkage to programme services, which emphasises the need to strengthen HIV prevention programmes from first contact with female sex workers in Zimbabwe. New infections among female sex workers remain challenging to measure, but longitudinal analysis of routine testing data can provide valuable insights into seroconversion rates and associated risk factors.

RESUMO

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.

RESUMO

BACKGROUND: Data on human immunodeficiency virus (HIV) seroconversion among men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) in West Africa are needed. This study aimed to document HIV seroconversion and associated determinants, PrEP adherence, plasma drug concentrations, and HIV drug resistance in MSM using event-driven or daily PrEP in Burkina Faso, Côte d'Ivoire, Mali, and Togo. METHODS: A prospective cohort study was conducted in 2017-2021 among HIV-seronegative MSM aged 18 or over who were at high risk of HIV infection. Participants could choose between event-driven and daily PrEP, switch regimens, and discontinue or restart PrEP. The determinants of HIV incidence were investigated using a multivariate mixed-effects Poisson regression analysis. RESULTS: A total of 647 participants were followed for a total time of 1229.3 person-years. Of 5371 visits, event-driven PrEP was chosen in 3873 (72.1%), and daily PrEP in 1400 (26.1%). HIV incidence was 2.4 per 100 person-years (95% confidence interval [CI] 1.5-3.6) for event-driven PrEP, and 0.6 per 100 person-years (95% CI .1-2.3) for daily PrEP (adjusted incidence rate ratio 4.40, 95% CI 1.00-19.36, P = .050). Adequate adherence was lower with event-driven than daily PrEP (44.3% vs 74.9%, P < .001). Plasma drug concentrations were undetectable in 92 (97.9%) of the 94 measures taken for 23 participants who seroconverted. Only 1 participant had resistance to PrEP drugs. CONCLUSIONS: HIV seroconversions mainly occurred in participants who chose event-driven PrEP. The study's data highlighted major difficulties with adherence to this regimen. Improving adherence to event-driven PrEP constitutes a major research and public health priority in this context.

RESUMO

BACKGROUND: People with HIV generally have more ageing-associated comorbidities than those without HIV. We aimed to establish whether the difference in comorbidities and their disease burden changes with ageing. METHODS: In this prospective, longitudinal cohort study, we assessed comorbidities commonly associated with ageing every 2 years in 596 HIV-positive and 550 HIV-negative participants. HIV-positive participants were recruited from the HIV outpatient clinic of the Amsterdam University Medical Centres (Amsterdam, Netherlands). HIV-negative participants were recruited from the sexual health clinic and the Amsterdam Cohort Studies at the Public Health Service of Amsterdam (Amsterdam, Netherlands). Inclusion criteria were participants aged 45 years or older and, for HIV-negative participants, a documented HIV-negative antibody test. The mean number of comorbidities present over time was compared between groups by use of Poisson regression, accounting for dropout and death through joint survival models. Mean disability-adjusted life-years (DALYs) accrued during 2-year intervals were compared between groups by use of an exponential hurdle model. FINDINGS: Between Oct 29, 2010, and Oct 9, 2012, participants were enrolled and then prospectively followed up until their last visit before Oct 1, 2018. 1146 participants were followed up for a median 5·9 years (IQR 5·7-6·0), during which 231 participants (20·2%) dropped out: 145 (24·3%) of 596 HIV-positive and 86 (15·6%) of 550 HIV-negative. 38 (3·3%) of 1146 participants died: 31 (5·2%) of 596 HIV-positive and seven (1·3%) of 550 HIV-negative. 24 HIV-positive and two HIV-negative participants died from ageing-associated comorbidities. 15 HIV-positive participants versus one HIV-negative participant died from non-AIDS malignancies. At inclusion, mean number of comorbidities was higher in HIV-positive participants (0·65) than in HIV-negative participants (0·32; p<0·0001). Mean number of comorbidities increased at similar rates over time: rate ratio (RR) per year for HIV-positive participants 1·04 (95% CI 1·00-1·08), RR per year for HIV-negative participants 1·05 (1·01-1·08; pinteraction=0·78). Number of comorbidities was associated with an increased risk of death (hazard ratio 3·33 per additional comorbidity, 95% CI 2·27-4·88; p<0·0001). HIV-positive participants had higher increases in mean DALYs than HIV-negative participants (0·209 per year, 95% CI 0·162-0·256 vs 0·091 per year, 0·025-0·157; pinteraction=0·0045). This difference was reduced when deaths were excluded in establishing DALYs (0·127, 0·083-0·171 vs 0·066, 0·005-0·127; pinteraction =0·11). INTERPRETATION: The larger comorbidity prevalence in HIV-positive participants aged 50-55 years on effective antiretroviral treatment than in HIV-negative participants increased similarly as participants aged and was associated with an increased risk of death, particularly of non-AIDS malignancies. Our findings reinforce the need for strategies to optimise prevention, screening, and early intervention.

RESUMO

Herpes simplex virus type 2 (HSV-2) is common globally and contributes significantly to the risk of acquiring HIV-1, yet these two sexually transmitted infections have not been sufficiently characterized for sexual and gender minorities (SGM) across Sub-Saharan Africa. To help fill this gap, we performed a retrospective study using plasma and serum samples from 183 SGM enrolled at the Lagos site of the TRUST/RV368 cohort in Nigeria, assayed them for HSV-2 antibodies with the Kalon ELISA and plasma cytokines and chemokines with Luminex, and correlated the findings with HIV-1 viral loads (VLs) and CD4 counts. We found an overall HSV-2 prevalence of 36.6% (49.5% and 23.9% among SGM with and without HIV-1, respectively, p < .001). Moreover, HSV-2-positive status was associated with high circulating concentrations of CCL11 among antiretroviral therapy-treated (p = .031) and untreated (p = .015) participants, and with high concentrations of CCL2 in the untreated group (p = .004), independent of VL. Principal component analysis revealed a strong association of cytokines with HIV-1 VL independent of HSV-2 status. In conclusion, our study finds that HSV-2 prevalence among SGM with HIV-1 is twice as high than HSV-2 prevalence among SGM without HIV-1 in Lagos and suggests that this is associated with higher levels of certain systemic cytokines. Additional work is needed to further characterize the relationship between HSV-2 and HIV-1 in SGM and help develop targeted therapies for coinfected individuals.

RESUMO

Prevalence of hypertension (HTN) and human immunodeficiency virus (HIV) are high among men while screening rates are low. Assisted partner notification service is a strategy recommended by the World Health Organization that aims to increase HIV testing and treatment uptake and may present an opportunity to offer integrated HIV/HTN screening and treatment services. In this prospective cohort study, we assessed the feasibility of integrating HTN screening for male sexual partners of females newly tested HIV-positive in 10 health facilities in Kenya. Participants were notified of the exposure and offered HIV testing and HTN screening; if they accepted and tested positive for either HTN, HIV, or both, they were referred for care. HTN was defined as systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90, or the use of antihypertensive medication. Among 1313 male partners traced, 99% accepted HIV testing and HTN screening. Overall, 4% were found to have HTN, 29% were in the pre-HTN stage, and 9% were HIV-positive. Only 75% had previously been screened for HTN compared to 95% who had previously tested for HIV. A majority preferred non-facility-based screening. The participants who refused HTN screening noted time constraints as a significant hindrance. HIV and HTN screening uptake was high in this hard-to-reach population of men aged 25 to 50. Although HTN rates were low, an integrated approach provided an opportunity to detect those with pre-HTN and intervene early. Strategic integration of HTN services within assisted partners services may promote and normalize testing by offering inclusive and accessible services to men.

RESUMO

BACKGROUND: HIV-1 infections initiated by multiple founder variants are characterised by a higher viral load and a worse clinical prognosis than those initiated with single founder variants, yet little is known about the routes of exposure through which transmission of multiple founder variants is most probable. Here we used individual patient data to calculate the probability of multiple founders stratified by route of HIV exposure and study methodology. METHODS: We conducted a systematic review and meta-analysis of studies that estimated founder variant multiplicity in HIV-1 infection, searching MEDLINE, Embase, and Global Health databases for papers published between Jan 1, 1990, and Sept 14, 2020. Eligible studies must have reported original estimates of founder variant multiplicity in people with acute or early HIV-1 infections, have clearly detailed the methods used, and reported the route of exposure. Studies were excluded if they reported data concerning people living with HIV-1 who had known or suspected superinfection, who were documented as having received pre-exposure prophylaxis, or if the transmitting partner was known to be receiving antiretroviral treatment. Individual patient data were collated from all studies, with authors contacted if these data were not publicly available. We applied logistic meta-regression to these data to estimate the probability that an HIV infection is initiated by multiple founder variants. We calculated a pooled estimate using a random effects model, subsequently stratifying this estimate across exposure routes in a univariable analysis. We then extended our model to adjust for different study methods in a multivariable analysis, recalculating estimates across the exposure routes. This study is registered with PROSPERO, CRD42020202672. FINDINGS: We included 70 publications in our analysis, comprising 1657 individual patients. Our pooled estimate of the probability that an infection is initiated by multiple founder variants was 0·25 (95% CI 0·21-0·29), with moderate heterogeneity (Q=132·3, p<0·0001, I2=64·2%). Our multivariable analysis uncovered differences in the probability of multiple variant infection by exposure route. Relative to a baseline of male-to-female transmission, the predicted probability for female-to-male multiple variant transmission was significantly lower at 0·13 (95% CI 0·08-0·20), and the probabilities were significantly higher for transmissions in people who inject drugs (0·37 [0·24-0·53]) and men who have sex with men (0·30 [0·33-0·40]). There was no significant difference in the probability of multiple variant transmission between male-to-female transmission (0·21 [0·14-0·31]), post-partum transmission (0·18 [0·03-0·57]), pre-partum transmission (0·17 [0·08-0·33]), and intra-partum transmission (0·27 [0·14-0·45]). INTERPRETATION: We identified that transmissions in people who inject drugs and men who have sex with men are significantly more likely to result in an infection initiated by multiple founder variants, and female-to-male infections are significantly less probable. Quantifying how the routes of HIV infection affect the transmission of multiple variants allows us to better understand how the evolution and epidemiology of HIV-1 determine clinical outcomes.

RESUMO

BACKGROUND: Assessing the maternal mental health status during the coronavirus disease 2019 (COVID-19) pandemic is necessary to prevent the occurrence of severe mental disorders. Prenatal depression, anxiety and stress disorders are prominent in pregnant women living with human immunodeficiency virus (HIV) and highly associated with poor maternal and neonatal outcomes. Therefore this study aimed to assess the level of depression, anxiety, and stress among HIV-positive pregnant women in Ethiopia during the COVID-19 pandemic. METHODS: An institution-based cross-sectional study was conducted in Amhara region referral hospitals from 17 October 2020 to 1 March 2021. A systematic random sampling technique was used to select 423 eligible women. A structured, pretested and interviewer-administered questionnaire was employed to collect the data. A multivariable logistic regression analysis was implemented to identify factors associated with women's depression, anxiety and stress. Statistical association was certain based on the adjusted odds ratio (AOR) with its 95% confidence interval (CI) and p-values ≤0.05. RESULTS: Prenatal depression, anxiety and stress among HIV-positive pregnant women were 37.6% (95% CI 33 to 42.3), 42.1 (95% CI 37.7 to 46.7) and 34.8% (95% CI 30.3 to 39.2), respectively. Having an HIV-negative sexual partner (AOR 1.91 [95% CI 1.16 to 3.15]) and being on antiretroviral therapy >1 year (AOR 2.18 [95% CI 1.41 to 3.36]) were found to be statistically significant with women's antenatal depression, while unplanned pregnancy (AOR 1.09 [95% CI 1.02 to 2.33]) and did not discuss with the sexual partner about HIV (AOR 3.21 [95% CI 2.12 to 7.07]) were the factors associated with prenatal anxiety. CONCLUSIONS: In this study, more than one in three HIV-positive pregnant women had depression and anxiety. Thus, implementing strategies to prevent unplanned pregnancy and advocating open discussion with sexual partners about HIV will play a large role in reducing pregnancy-related depression and anxiety.

RESUMO

BACKGROUND: Over the past decade, the incidence of primary and secondary syphilis has increased dramatically in the United States and Western Europe. Men living with human immunodeficiency virus (HIV) and those at risk of HIV infection experience disproportionately high rates of early syphilis (ES). We compared the odds of ES among HIV-positive and HIV-negative men participating in a status-neutral comprehensive HIV prevention and treatment program (CHP). METHODS: We conducted a retrospective analysis of men aged 18 to 65 years with ≥ 1 CHP visit and ≥2 rapid plasma reagin (RPR) tests performed between January 1, 2018, and December 31, 2021. Early syphilis was defined as newly reactive RPR with a minimum titer of ≥1:4 or a ≥ 4-fold increase in the RPR titer. Multiple logistic regression analyses were performed to determine predictors of ES. RESULTS: A total of 2490 men met the inclusion criteria, of whom 1426 (57.3%) were HIV-positive and 1064 (42.7%) were HIV-negative. Of the 393 men with ES, 284 (72.3%) were HIV-positive and 109 (27.7%) were HIV-negative. Human immunodeficiency virus-positive men had higher adjusted odds of ES (adjusted odds ratio, 2.86; 95% confidence interval, 2.45-3.27) than HIV-negative men did. Chlamydia or gonorrhea infection did not differ according to HIV status (adjusted odds ratio, 0.93; 95% confidence interval, 0.82-1.04). CONCLUSIONS: In our status-neutral care setting, HIV-positive status was associated with significantly higher odds of ES, but not chlamydia or gonorrhea. Our findings emphasize the vulnerability of HIV-positive men to syphilis in an era of effective HIV biomedical prevention.

RESUMO

BACKGROUND: A large number of HIV-1 recombinants that originated from CRF01_AE and B strains are constantly emerging in men who have sex with men populations in China and deserve more attention and further monitoring. OBJECTIVE: To analyze the near-full-length genome structure and recombination characteristics of a new HIV-1 strain (BD226AJ) detected in Baoding City and determine its subtype. CASE REPRESENTATION: Viral RNA was extracted from a blood sample collected from an infected individual and reverse transcribed to cDNA. Two overlapping segments of the HIV-1 genome were amplified using a near-endpoint dilution method and sequenced. Recombinant breakpoints were determined using RIP, jpHMM, and SimPlot 3.5.1 software. MEGA v6.0 was used to construct a neighbor-joining phylogenetic tree to determine the homology relationships of this strain. RESULTS AND DISCUSSION: We obtained 8830 nucleotides (nt) of the HIV-1 genome sequence by amplification and sequencing, and four recombinant fragments were identified by recombination analysis, namely CRF01_AE (HXB2, 823-4224 nt), subtype B (HXB2, 4225-5991 nt), CRF01_AE (HXB2, 5992-9295 nt), and subtype B (HXB2, 9296-9406 nt). The BLAST results showed that 96% of the sequence was similar to CRF112_01B. The jpHMM results confirmed that BD226AJ was the CRF112_01B strain. CONCLUSION: Our results confirm the first epidemic of CRF112_01B in Hebei Province. This finding suggests that HIV-1 CRF112_01B may have been introduced into Hebei by men who have sex with men and indicates that the epidemic trend of this strain should be closely monitored.

RESUMO

BACKGROUND: HIV-positive men who have sex with men (MSM) are more likely to experience human papillomavirus (HPV) infection. The persistent HPV infection is the major factor in the development of anal and oropharyngeal neoplasms. Data on the prevalence of anal and oral HPV in MSM are almost absent from the countries of Central and Eastern Europe. We conducted a cross-sectional study focused on the prevalence of oral and anal HPV infections and the relationship between current anal and oral HPV intrapersonal infection in a Czech population of predominantly HIV-positive MSM. METHODS: Oral gargle and anal swab samples from 205 predominantly HIV-positive MSM from the Czech Republic were analysed for HPV infection using PCR. Selected sociodemographic and clinical data were correlated with HPV detection using generalized linear models and multivariate analysis. RESULTS: HPV infection was detected in 183 (96.8%) anal and 48 (23.6%) oral samples. The most common type of HR-HPV was HPV16 in both anal (25.4%) and oral (2.5%) samples. Multiple anal HPV infections and the presence of vaccine-targeted HR-HPV types were significantly correlated with abnormal anal cytology and HIV status. CONCLUSION: The prevalence of anal HPV infection in Czech predominantly HIV-positive MSM ranks among the highest reported, while oral HPV prevalence is consistent with MSM populations. Minimal overlap of oral and anal HPV types within a patient was observed.

RESUMO

OBJECTIVES: This systematic review and meta-analysis aimed to assess the pooled estimate of option B+ level of adherence and its association with disclosure status and counseling among pregnant and lactation women in Ethiopia after option B+ implementation. STUDY DESIGN: Systematic review and meta-analysis. METHODS: We searched Web of Science, MEDLINE, PUBMED, Scopus, Embase, CINAHL, and Google Scholar databases for studies reporting adherence to option B+ and its association with disclosure status and counseling among pregnant and lactating women in Ethiopia. Heterogeneity was assessed by forest plot, Cochran's Q test, and I2 test. A random effects model was calculated to estimate the pooled prevalence of adherence toward option B+. RESULTS: We included eight studies, which gives a total of 1852 pregnant and lactating women in this systematic review and meta-analysis. The overall pooled estimate of good adherence toward option B+ antiretroviral therapy (ART) drug among pregnant and lactating women in Ethiopia was 84.23% (95% confidence interval [CI]: 80.79-87.66). Women who have disclosed their HIV status to their partner (adjusted odds ratio = 4.48, 95% CI: 1.86-10.76) and got counseling during the antenatal period (adjusted odds ratio = 5.02, 95% CI: 2.43-10.34) had a positive association with good adherence to option B+ ART drugs. CONCLUSION: Four of five pregnant and lactating women have good adherence to option B+ ART drugs in Ethiopia. Therefore, promoting HIV disclosure status to partners and enhancing counseling services should be strengthened to improve adherence toward option B+ among pregnant and lactating women.

RESUMO

Introduction: HIV-positive status disclosure for children is challenging for family members, guardians, and healthcare professionals. Disclosure is very challenging, particularly for children, yet no systematic synthesis of evidence accurately measures HIV-positive status disclosure in children. This systematic review and meta-analysis study aimed to quantify the national prevalence of pediatric HIV-positive status disclosure in Ethiopia and identify factors associated with HIV-positive status disclosure. Method: We systematically searched PubMed, EMBASE, Web of Science databases, and google scholar for relevant published studies. Studies published in the English language and conducted with cohort, case-control, and cross-sectional designs were eligible for the review. The primary and secondary outcomes of the study were HIV-positive status disclosure and factors associated with HIV-positive status disclosure, respectively. The quality of the included studies was assessed using the Joanna Briggs Institute critical appraisal tools. A random effect- model was used to estimate the pooled prevalence of HIV-positive status disclosure. Heterogeneity and publication bias of included studies was determined using I2 and Egger's test, respectively. Result: From 601 records screened, nine relevant studies consisting of 2,442 HIV-positive children were included in the analysis. The overall pooled prevalence of HIV-positive status disclosure among children living with HIV/AIDS in Ethiopia was 31.2% (95% CI [23.9-38.5]). HIV-negative status of caregivers (AOR: 2.01; 95% CI [1.28-3.18]), long duration on ART (greater than 5 years) (AOR: 3.2; 95% CI [1.77-5.78]) and older age of the child (>10 years) (AOR: 7.2; 95% CI [4.37-11.88]) were significantly associated with HIV-positive status disclosure. Conclusion: Low prevalence of pediatric HIV-positive status disclosure was observed in Ethiopia. The longer duration of ART, the HIV-negative status of the caregiver, and older age greater than 10 years were the predictors of pediatric HIV-positive status disclosure. Health system leaders and policymakers shall design training and counseling programs for healthcare professionals and caregivers to enhance their awareness about HIV-positive status disclosure. Trial registration: This review was registered under PROSPERO and received a unique registration number, CRD42019119049.

RESUMO

In 2019, an outbreak of HIV infection predominantly affecting children occurred in Larkana district, Pakistan. This is the largest outbreak ever reported in this age group in Pakistan. In this study, we report two HIV-1 unique recombinant forms identified during the outbreak. Blood samples were collected from HIV-positive children as part of a case-control study to investigate the outbreak. The pol gene was sequenced and used to detect HIV subtype/recombinant forms using subtype, recombination, and phylogenetic analyses. Drug resistance mutation (DRM) analysis was performed to characterize the DRMs in each sequence. We observed the emergence of two unassigned unique recombinant forms related to CRF36_cpx in 15 individuals of the 344 samples collected. Genotype analysis revealed the presence of multiple DRMs associated with resistance to reverse transcriptase inhibitors. The discovery of these unassigned unique recombinant forms in our population highlights the need for comprehensive molecular epidemiological studies to fully understand the distribution and drug resistance patterns to aid control efforts.

RESUMO

Abstract Objectives: to estimate the proportion of seroconversion cases among infants exposed to HIV and verify the risk factors associated. Methods: this was a historical cohort study conducted in the State of Santa Catarina between 2007 and 2017. The data were obtained from the Notifable Diseases Information System (SINAN - Portuguese acronym) that records HIV-infected pregnant women and HIV-exposed infants. The public health service monitored the infants from birth to 18 months of age to determine whether HIV seroconversion occurred. Results: a total of 5,554 HIV-infected pregnant women were included in the study (mean age 26.7±6.5 years). They were predominantly white, with poor education level, and were diagnosed with HIV until the 2nd trimester of pregnancy. A total of 4,559 records of HIV-exposed infants were screened, of which 130 cases (2.9%) of seroconversion were confrmed. Non-use of antiretroviral drugs during pregnancy (OR=9.31, CI95%=5.97-14.52; p<0.001) and breastfeeding (OR=3.10, CI95%=1.34-7.20; p=0.008) were independent risk factors for seroconversion. Conclusions: these data demonstrate gaps in prenatal care, regarding adherence to treatment and monitoring of HIV-infected mothers, resulting in new cases of HIV among children, which could be avoided.


Resumo Objetivos: estimar a proporção de soroconversão da criança exposta ao HIV e verificar os fatores de risco associados, no período de 2007-2017 em Santa Catarina. Métodos: o delineamento utilizado foi de coorte histórica e os dados obtidos no Sistema de Informação de Agravos de Notificação (SINAN) que registra as gestantes infectadas e as crianças expostas ao HIV. As crianças foram acompanhadas pelo serviço de saúde desde o nascimento até o 18º mês de vida, para determinar a ocorrência de soroconversão pelo HIV. Resultados: foram identificadas 5.554 gestantes infectadas pelo HIV com média de idade de 26,7±6,5 anos, predomínio da raça branca, baixa escolaridade e que receberam o diagnóstico para o HIV até o 2º trimestre gestacional. Foram incluídas 4.559 fichas de crianças expostas ao HIV, das quais 130 casos (2,9%) de soroconversão foram confrmados. O não uso de antirretroviral durante a gestação (OR=9,31, IC95%=5,97-14,52; p<0,001) e aleitamento materno (OR=3,10, IC95%=1,34-7,20; p=0,008) foram fatores de risco independentes para a soroconversão. Conclusões: esses dados demonstram lacunas na assistência pré-natal, quanto a adesão ao tratamento e acompanhamento de mães infectadas pelo HIV, resultando em casos novos de HIV entre crianças, que poderiam ser evitados.

RESUMO

AIM: The initial cases of COVID-19 appeared in December 2019 and Spain was one of the most affected countries during the first wave (March to June). Since then, HIV HGM BioBank has been restructured as an established Paediatrics and Adults HIV_COVID-19 BioBank that aims at the long-term storage of samples obtained from not only HIV-1, but also from COVID-19 patients and HIV-1_COVID-19 coinfected patients. METHODS: HIV HGM BioBank holds high quality biological samples from newborns, children, adolescents and adults with their associated clinical data. Research groups trying to establish large networks focused on research on specific clinical problems in epidemiology, biology, routes of transmission and therapies, are potential users of the clinical samples and of associated data of HIV-1_COVID-19 HGM BioBank. RESULTS: The HIV HGM BioBank is an academic and ethical enterprise complying with all the legal regulatory rules to provide service to the society. HIV_COVID-19 HGM BioBank has been repurposed to offer an important resource for global research of COVID-19 in newborns, children, adolescents, adults and elders to study the biological effect of the pandemic. CONCLUSION: Herein, we present a description of how HIV HGM BioBank has rapidly become an indispensable structure in modern biomedical research, including COVID-19 research.
