The PrEP cascade in a sample of HIV-negative or unknown status adolescent and young adult transgender women in Peru

Background Transgender women are a key population in the HIV epidemic globally, including in Peru. This cross-sectional epidemiological study characterized the pre-exposure prophylaxis (PrEP) cascade in adolescent and young adult transgender women in Peru to inform roll-out of early HIV prevention efforts. Methods Between February-July 2022, a community-recruited sample of HIV-negative or status unknown young transgender women ( n = 140) in Peru completed a socio-behavioral survey and biological testing for HIV and bacterial STIs. Logistic regression models estimated the association of sociodemographic, healthcare, and behavioral factors to PrEP indication and willingness. Results Median age was 22 years (range = 16-24 years); 65.7% reported sex work and 28.6% homelessness. Overall, 45.7% had a PrEP indication based on past 6 months HIV behavioral risk profiles. In a multivariable model, sex work (aRR = 2.27; 95% CI = 1.24-4.17) and homelessness (aRR = 1.27; 95% CI = 1.00-1.60) were associated with PrEP indication. More than one-third (38.6%) had never been HIV tested; 25.3% were tested >1 year ago. Only 34.3% heard of daily oral PrEP, 8.6% reported ever PrEP use, and 5.0% current PrEP use. Nearly half (49.3%) reported willingness to take daily oral PrEP. In a multivariable model, younger age was associated with increased willingness to use PrEP (aRR = 0.92; 95% CI = 0.87-0.98). Highest ranked PrEP preferences were a daily oral pill (35.7%), implant (32.1%), and injection by a provider (10.0%). Conclusions PrEP indication and willingness were high in this sample, but HIV testing and PrEP uptake were low. Findings highlight opportunities for age-responsive and contextually-relevant interventions to increase HIV prevention among young transgender women in Peru.

Co-Infection of Cytomegalovirus and Leishmania without Splenomegaly Resulting in Immunosuppression in an Hiv-Negative Patient.

Leishmaniasis is caused by the parasite Leishmania donovani and transmitted by the bite of the sand fly vector Phlebotomus. This disease is endemic in the Bihar region of India. There are three common forms of the disease - cutaneous, mucosal and visceral leishmaniasis. The most common presentation of this disease is prolonged unexplained fever with hepatosplenomegaly. We report an unusual case of pyrexia of unknown origin (PUO) in a patient who was extensively worked up for PUO. She was found to have low CD4 counts even though serial samples were negative for HIV. Workup for PUO revealed a positive result for cytomegalovirus (CMV) IgM and polymerase chain reaction (PCR), fundoscopy suggestive of CMV retinitis and bone marrow biopsy suggestive of visceral leishmaniasis. Interestingly, there was no evidence of hepatosplenomegaly. She was diagnosed as a case of CMV infection and visceral leishmaniasis resulting in immunosuppression and was managed with parenteral ganciclovir followed by oral valganciclovir and amphotericin respectively. She had a dramatic response to the treatment and was discharged after two months of in hospital management. Co-infection of CMV and Leishmania in an immunocompromised patient with HIV-negative status without hepatosplenomegaly posed a diagnostic dilemma and is a rare presentation. This report shows the importance of diagnosis of this co-infectious state, which upon management with ganciclovir and amphotericin lead to resolution of symptoms and pancytopenia. Clinicians should be aware of the unusual presentation to avoid missing the diagnosis of this potentially life-threatening treatable condition. Visceral leishmaniasis without splenomegaly is a rare presentation.Other aetiologies for low CD4 counts in an HIV-negative patient such as cytomegalovirus (CMV) should be considered.Co-infection of CMV and Leishmania resulting in immunosuppression in an HIV-negative patient is rare and poses a diagnostic dilemma.

Prevalence and risk factors of human papilloma virus infection among women living with HIV, Egypt, a cross sectional study

BackgroundHPV is considered the most common sexually transmitted infection. It is responsible of 70% of cervical cancers worldwide. HIV infection is associated with increased rates of HPV infection. Women Living With HIV (WLWH) are 6 times at greater risk of developing cervical cancer. The current study aimed to estimate prevalence and identify genotypes of HPV infection among WLWH in Egypt compared to women with negative HIV status and determine associated risk factors.MethodsThe study conducted among 251 WLWH and 268 women with negative HIV status enrolled from gynecological clinics in primary health care centers from nine Egyptian governorates. Data was collected from participants using a structured interview questionnaire and cervical samples were collected for HPV DNA detection and genotyping.ResultsThe overall prevalence of HPV infection was 13.5%, 3.4% among women with HIV negative status and 24.4% among WLWH. HR-HPVs other than genotype 16 and 18 were isolated from 71% of infected women. Woman’s age, age at first marriage, number of lifetime marriages and drug addiction are significant predictors for HPV infection (odds 0.96, 0.91, 2.06, 2.01 respectively).ConclusionHPV infection is more prevalent among WLWH. Infection with HR-HPV other than genotype 16 and 18 was the most prevalent among infected women in both groups. Young age, early life sexual activity, having more than one sexual partner during the life time, and drug addiction are independent predictors for HPV infection. Having a husband who has had other sexual partners is significantly associated with infection.

Treatment Results in Patients with Drug Resistant Tuberculosis (MDR, pre-XDR, XDR) and HIV Infection in Stavropol Region

The objective: to compare treatment effectiveness of drug resistant tuberculosis (MDR, pre-XDR, XDR) depending on the HIV status of patients in Stavropol Region from 2019 to 2022.Subjects and Methods. In a retrospective study, chemotherapy outcomes for pulmonary tuberculosis (TB) were evaluated with distribution by treatment regimens for MDR, pre-XDR, and XDR in 100 patients with drug resistant tuberculosis (MDR, pre-XDR, XDR and HIV infection (DR TB/HIV Group ) and 707 patients with drug resistant tuberculosis (MDR, pre-XDR, and XDR) (and negative HIV status (DR TB Group). The immune status of patients in DR TB/HIV Group and its impact on the effectiveness of tuberculosis treatment were analyzed.Results. Effective treatment (definitions are given according to the Guidelines) was statistically significantly more frequently registered in DR TB Group versus DR TB/HIV Group (59% and 48%, respectively, p<0.05). Treatment failure was statistically significantly more frequently registered in patients in DR TB/HIV Group versus DR TB Group (42% and 26%, respectively, p<0.05). In DR TB/HIV Group, the lowest effectiveness (33%) of tuberculosis treatment was noted in the patients with CD4 count below 200 cells/µL. Among those died, the median time to death from the start of tuberculosis treatment was 12 months in DR TB Group, 8 months in DR TB/HIV Group, and 4 months in the subgroup of patients with CD4 count below 100 cells/µL.

Associations between perceived and actual risk of HIV infection and HIV prevention services uptake among men who have sex with men in Shandong province, China: a cross-sectional study

BackgroundAssociations between perceived and actual risk of HIV infection and HIV prevention services uptake are inconclusive. This study aimed to evaluate the discrepancy between the perceived and actual HIV risk, and quantify the associations between perceived and actual risk of HIV infection and three HIV prevention services utilization among men who have sex with men (MSM) in Shandong province, China.MethodsA cross-sectional study was conducted in Shandong province in June 2021. Participants were eligible if they were born biologically male, aged 18 years or older, had negative or unknown HIV status, and had sex with men in the past year. Participants were recruited online. The discrepancy between their perceived and actual risk of HIV infection was evaluated by calculating the Kappa value. Bayesian model averaging was used to assess the associations between perceived and actual risk of HIV infection and HIV prevention services uptake.ResultsA total of 1136 MSM were recruited, most of them were 30 years old or younger (59.9%), single (79.5%), with at least college education level (74.7%). Most participants (97.4%) perceived that they had low risk of HIV infection, and 14.1% were assessed with high actual risk. The discrepancy between their perceived and actual risk of HIV infection was evaluated with a Kappa value of 0.076 (P < 0.001). HIV testing uptake had a weak association with perceived high HIV prevalence among social networks (aOR = 1.156, post probability = 0.547). The perceived high HIV prevalence among national MSM was positive related to willingness to use PrEP (aOR = 1.903, post probability = 0.943) and PEP (aOR = 1.737, post probability = 0.829). Perceived personal risk (aOR = 4.486, post probability = 0.994) and perceived HIV prevalence among social networks (aOR = 1.280, post probability = 0.572) were related to history of using PrEP. Perceived personal risk (aOR = 3.144, post probability = 0.952), actual risk (aOR = 1.890, post probability = 0.950), and perceived risk among social networks (aOR = 1.502, post probability = 0.786) were related to history of using PEP.ConclusionsThere is discordance between perceived and actual personal risk of HIV infection among MSM in China. HIV risk assessment and education on HIV prevalence among MSM should be strengthened to assist high-risk populations aware their risk accurately and hence access HIV prevention services proactively.

Crosstalk between human immunodeficiency virus infection and salivary bacterial function in men who have sex with men.

Engaging in anal sexual intercourse markedly increases the risk of developing HIV among men who have sex with men (MSM); oral sexual activities tend to uniquely introduce gut-derived microbes to salivary microbiota, which, combined with an individual's positive HIV status, may greatly perturb oral microecology. However, till date, only a few published studies have addressed this aspect. Based on 16S rRNA sequencing data of bacterial taxa, MicroPITA picks representative samples for metagenomic analysis, effectively revealing how the development and progression of the HIV disease influences oral microbiota in MSM. Therefore, we collected samples from 11 HIV-negative and 44 HIV-positive MSM subjects (stage 0 was defined by HIV RNA positivity, but negative or indeterminate antibody status; stages 1, 2, and 3 were defined by CD4+ T lymphocyte counts ≥ 500, 200-499, and ≤ 200 or opportunistic infection) and selected 25 representative saliva samples (5 cases/stage) using MicroPITA. Metagenomic sequencing analysis were performed to explore whether positive HIV status changes salivary bacterial KEGG function and metabolic pathway in MSM. The core functions of oral microbiota were maintained across each of the five groups, including metabolism, genetic and environmental information processing. All HIV-positive groups displayed KEGG functions of abnormal proliferation, most prominently at stage 0, and others related to metabolism. Clustering relationship analysis tentatively identified functional relationships between groups, with bacterial function being more similar between stage 0-control groups and stage 1-2 groups, whereas the stage 3 group exhibited large functional changes. Although we identified most metabolic pathways as being common to all five groups, several unique pathways formed clusters for certain groups; the stage 0 group had several, while the stage 2 and 3 groups had few, such clusters. The abundance of K03046 was positively correlated with CD4 counts. As HIV progresses, salivary bacterial function and metabolic pathways in MSM progressively changes, which may be related to HIV promoting abnormal energy metabolism and exacerbate pathogen virulence. Further, infection and drug resistance of acute stage and immune cell destruction of AIDS stage were abnormally increased, predicting an increased risk for MSM individuals to develop systemic and oral diseases.

Awareness of U = U among Sexual and Gender Minorities in Brazil, Mexico, and Peru: Differences According to Self-reported HIV Status

The slogan Undetectable equals Untransmittable (U = U) communicates that people living with HIV (PLHIV) who are on antiretroviral therapy (ART) will not transmit HIV to their sexual partners. We describe awareness of U = U among sexual and gender minorities (SGM) living in Brazil, Mexico, and Peru by self-reported HIV status (PLHIV, negative, unknown) during 2021 using an online survey. We estimated two models using Poisson regression for each population group: Model A including socio-demographic factors (country, gender, age, race, education, and income), and then Model B including taking ART (for PLHIV) or risk behavior, ever-taking PrEP, and HIV risk perception (for HIV-negative or of unknown HIV status). A total of 21,590 respondents were included (Brazil: 61%, Mexico: 30%, Peru: 9%). Among HIV-negative (74%) and unknown status (12%), 13% ever used PrEP. Among PLHIV (13%), 93% reported current use of ART. Awareness of U = U was 89% in both Brazil and Mexico, which was higher than in Peru 64%. Awareness of U = U was higher among PLHIV (96%) than HIV-negative (88%) and HIV-unknown (70%). In multivariate models, PLHIV with lower education were less aware of U = U, while those taking ART were more aware. Among HIV-negative, non-cisgender, lower income, and those with lower education had lower awareness of U = U, while individuals ever using PrEP had higher awareness. In conclusion, awareness of U = U varied by HIV status, socio-demographic characteristics, and HIV risk behavior. The concept of U = U should be disseminated through educational strategies and include a focus on SGM to combat HIV stigma.

Molluscum Contagiosum Profile At The Dermatology And Venereology Polyclinic Of Prof. I.G.N.G. Ngoerah Central General Hospital Denpasar

Molluscum contagiosum (MC) is a viral infectious disease caused by the Molluscum Contagiosum Virus (MCV). There are four subtypes of MCV (MCV-1, MCV-2, MCV-3, and MCV-4). The worldwide incidence of MK infection is estimated to be around 2% to 8%, while in the HIV/AIDS population, it is approximately 5% to 18%. To date, there is limited research reporting on the profile of MC patients in Indonesia. This is a descriptive cross-sectional research design. Data were obtained retrospectively and collected from the medical records of patients with molluscum contagiosum who visited the Dermatology and Venereology Polyclinic at Prof. I.G.N.G. Ngoerah General Hospital in Denpasar, Bali, from January 2018 to December 2020. In this study of molluscum contagiosum infection at the Dermatology and Venereology Polyclinic of Sanglah General Hospital in Denpasar, Bali, during the period of January 2018 to December 2020, the majority of participants were aged between 18-44 years (61.1%) and were male (61.1%). Most participants were from Bali (77.8%) and were married (55.6%). Moreover, the majority of participants were sexually active (77.8%) and had a negative HIV status (55.6%). Concerning sexual orientation, most participants identified as heterosexual (83.3%). Regarding the type of therapy received, most participants underwent enucleation (55.5%) and combination therapy (22.2%). Broad public education, especially for parents, regarding molluscum contagiosum should be enhanced to support more effective healthcare efforts encompassing treatment, prevention, and health promotion.

Tuberculosis treatment outcomes and associated factors among tuberculosis patients treated at healthcare facilities of Motta Town, Northwest Ethiopia: a five-year retrospective study

Tuberculosis (TB) remains a significant public health concern, particularly in low-resource settings. The treatment outcome is a crucial indicator of the effectiveness of TB treatment programs. Assessing the current treatment outcome and its associated factors is essential for improving patient care and reducing the spread of TB. Therefore, this study aimed to assess TB treatment outcomes and their associated factors among TB patients who received treatment at public healthcare facilities in Motta Town, Northwest Ethiopia. A facility-based retrospective cross-sectional study design was employed in two TB treatment centers in Motta town from January 2017 to December 2021. The study participants were all patients diagnosed with TB who received treatment. A p-value of 0.05 with a 95% confidence interval (CI) was used to determine statistical significance. A total of 362 TB patients were included in the study. The overall treatment success rate was 88.4% (95% CI 85.1, 91.7). Male gender (AOR = 2.40, 95% CI 1.16, 4.98), normal nutritional status (AOR = 3.11, 95% CI 1.33, 7.25), HIV negative status (AOR = 3.35, 95% CI 1.31, 8.60), and non-presumptive drug resistance to TB (AOR = 3.72, 95% CI 1.74, 7.98) were significantly associated with successful TB treatment outcomes (p < 0.05). In the current study, nine out of ten study participants had successful TB treatment outcome rates. Male gender, normal nutritional status, non-presumed drug resistance to TB, and HIV-negative status were significantly associated with successful TB treatment outcomes. By taking risk factors associated with poor treatment outcomes like those found in this study into account, patient management and treatment can be optimized. Sufficient TB control measures for populations are imperative and could significantly reduce the nation's total TB burden.

Continuing Low Awareness and Use of Pre-exposure Prophylaxis (PrEP) for HIV among People Who Inject Drugs (PWID), San Francisco, 2022.

Clinical trials provide evidence that pre-exposure prophylaxis (PrEP) prevents HIV acquisition including through sharing of injection equipment among people who inject drugs (PWID). However, uptake among many populations at risk for HIV has been slow, particularly among PWID. We examined data from the National HIV Behavioral Surveillance (NHBS) from San Francisco in 2022 to measure PrEP uptake and identify factors associated with PrEP awareness among PWID. Of 479 PWID with HIV-negative or unknown HIV status, 54.9% were aware of PrEP, 5.9% had discussed PrEP with a healthcare provider, and 1.5% had used PrEP in the past year. Lack of PrEP awareness was associated with being age 50 years and older (adjusted odds ratio [aOR] 0.40, 95% CI 0.27-0.60), being men who have sex with women (vs. men who have sex with men, aOR 0.47, 95% CI 0.24-0.92), having a disability (aOR 0.58, 95% CI 0.35-0.95), using heroin as their most frequently injected drug (aOR 0.51, 95% CI, 0.34-0.78), not having tested for HIV, HCV, or an STD in the past year (aOR 0.43, 95% CI 0.28-0.64), and not having access to new sterile needles in the past year (aOR 0.28, 95%CI 0.08-1.00). We found negligible change in the awareness and uptake of PrEP among PWID since previously measured in NHBS in 2018. Low PrEP use among PWID may be addressed by increasing provider discussion of PrEP with their PWID patients and clients during routine care, expanding testing for injection-related infections among PWID, and integrating PrEP access into harm reduction programs.

HIV status and knowledge of cervical cancer among women in Ghana

BackgroundCervical cancer remains a disease of significant concern to women’s health. The aim of this study was to identify predictors of knowledge of cervical cancer among women living with HIV and those with negative or unknown HIV status at the Cape Coast Teaching Hospital (CCTH).MethodsThis study was based on a larger hospital-based analytical cross-sectional study conducted at the antiretroviral therapy (ART) and gynaecology clinics of the Cape Coast Teaching Hospital in Ghana. Participants were women living with HIV (WLHIV) and women without HIV or whose status was unknown, aged 25 to 65 years, seeking healthcare. Data were collected with a questionnaire and analysed using frequencies, percentages, Chi-square test, binary logistic regression and multivariate analysis.ResultsThe mean age was 39.5 years (± 9.8) and 47.2 years (± 10.7) for women without or unknown HIV and WLHIV, respectively. HIV-negative/unknown women were mostly nulligravida (76%) and nullipara (69%), while WLHIV mostly had pregnancies (76%) and children (84%) in excess of seven. Knowledge of cervical cancer was statistically significantly associated with HIV status (X2 = 75.65; P-value = 0.001). The odds of having knowledge of cervical cancer for women considered to be negative/unknown for HIV were about three times (AOR = 3.07; 95% CI = 1.47, 6.41) higher than their compatriots with HIV. Women with post-secondary/tertiary (AOR = 4.45; 95% CI = 2.11, 9.35) education had significantly higher odds of having knowledge of cervical cancer than those with no education or those with just primary education.ConclusionsTo improve knowledge of cervical cancer among women, an intentionally structured health education programme is needed, particularly for WLHIV, those with lower levels of education and the unemployed.

Analysis on the use of HIV post-exposure prophylaxis and related factors in men who have sex with men in Qingdao

Objective: To understand the use of post-exposure prophylaxis (PEP) and analyze related factors among men who have sex with men (MSM) in Qingdao, and provide a reference for the AIDS prevention and control in this population. Methods: A cross-sectional survey conducted from April 2022 to February 2023. Relying on MSM social groups in Qingdao, a snowball sampling method was applied to recruit research subjects who met the inclusion criteria of age ≥18 years old, having had homosexual anal or oral sex in the past six months, and HIV-negative or infection status unknown. The sample size was estimated at 566. Data on demographic characteristics, sexual behavior characteristics, PEP use, and others of the research subjects was collected through on-site questionnaires. The logistic regression model was used to analyze the factors associated with using PEP. Results: A total of 811 participants were recruited, mainly aged 25-34 (53.6%, 435/811), unmarried (74.7%, 606/811), with an average monthly income of ≥5 000 yuan (52.2%, 423/811), and having lived in Qingdao for ≥10 years (75.6%, 613/811). The proportion of those who knew the HIV status of their sexual partners in the last six months was 67.1% (544/811), and those with HIV-positive partners were 3.6% (29/811). In the last six months, the proportion of participants who had group sex (86.4%, 701/811), unprotected anal sex (98.2%, 796/811), and use of club drugs (80.3%, 651/811) was high. Moreover, 28.4% (230/811) had used PEP. The multivariate logistic regression analysis showed that the factors related to the use of PEP included divorced or widowed (aOR=5.46,95%CI:1.96-15.17), average monthly income ≥5 000 yuan (aOR=2.04,95%CI:1.44-2.89), same-sex sexual orientation (aOR=0.40,95%CI:0.22-0.71), having HIV-positive sexual partners in the last six months (aOR=2.54,95%CI:1.13-5.71) and having been tested for HIV ≥3 times in the last six months (aOR=1.46,95%CI:1.04-2.06). Conclusions: The prevalence of risk behaviors among MSM in Qingdao was high, and the use of PEP was low. In the future, it is essential to increase HIV/AIDS prevention education among MSM, promote MSM to know the HIV status of their sexual partners, and reduce the prevalence of risk behaviors among this population. Additionally, explore medical insurance reimbursement plans for PEP to reduce utilization costs and promote the use of PEP by MSM after HIV exposure occurs as soon as possible.

Determinants of sputum culture conversion time in multidrug-resistant tuberculosis patients in ALERT comprehensive specialized hospital, Addis Ababa, Ethiopia: A retrospective cohort study.

The treatment response of multi-drug resistance tuberculosis (MDR-Tuberculosis) patients is mainly dictated by the sputum culture conversion. An earlier culture conversion is a remarkable indicator of the improvement in the treatment response. In this study, we aimed to determine the time to culture conversion and its associated factors among MDR-Tuberculosis patients in All Africa Leprosy, Tuberculosis and Rehabilitation Training Center (ALERT) Hospital, Addis Ababa, Ethiopia. A retrospective cohort study was conducted on 120 MDR-Tuberculosis patients attending ALERT Hospital from 2018-2022. Kaplan-Meier methods were used to determine the time to initial sputum culture conversion. All relevant laboratory, socio-demographic characteristics, and other clinical data were collected by chart abstraction using a structure data extraction form. The log-rank test was used to determine the survival rate. To identify the predictors of culture conversion, bivariate and multivariate Cox proportional hazard regression analysis was used. The hazard ratio (HR) with a 95% confidence interval was used to estimate the effect of each variable on the initial culture conversion. A test with a P value of < 0.05 was considered statistically significant. From the total of 120 study participants, 89.2% (107/120) have shown a successful culture conversion. The median age of the participants was 30 years (IQR = 12). The study participants were followed for 408.6 person-months (34.05 person-years). The median time to initial sputum culture conversion was 80 days. The median time to initial sputum culture conversion among HIV-positive and HIV-negative participants was 61 days (IQR = 58-63.5) and 88 days (IQR = 75-91), respectively. HIV-negative and patients with previous treatment history were shown to be the predictor for a prolonged time to initial sputum culture conversion, (aHR = 0.24 (95% CI: 0.1-0.4), P value <0.001) and (aHR = 0.47 (95% CI: 0.31-0.71), P value <0.001) respectively. The median time to sputum culture conversion for HIV positive was found to be 61 days in our study. Notably, patients with a history of previous anti-tuberculosis treatment, HIV-negative status, and higher bacillary load at baseline exhibited delayed culture conversion. These findings underscore the importance of considering such patient characteristics in the management of MDR-TB cases, as tailored interventions and close monitoring may lead to more favorable treatment outcomes. By identifying individuals with these risk factors early in the treatment process, healthcare providers can implement targeted strategies to optimize patient care and improve overall treatment success rates in MDR-TB management programs.

Experience of Fixed-Dose Combinations of Anti-Tuberculosis Drugs for Preventive Treatment in Children

The objective: to evaluate the effectiveness and safety of preventive treatment with fixed-dose combination of anti-tuberculosis drugs (FDCs) in children from groups at high risk of developing tuberculosis.Subjects and Methods. Effectiveness of preventive treatment was analyzed in 318 children from groups at high risk of developing tuberculosis. Also, we studied the possibility of successful completion of the full course of treatment using FDCs and preventive treatment regimens containing at least two single drugs. Inclusion criteria were as follows: the child at high risk of developing tuberculosis; no clinical and radiological signs of active tuberculosis; lack of information about the resistance to first-line drugs at the suspected source of infection; and negative HIV status. A group of children (172 people) underwent preventive treatment using FDCs, of them 126 patients received FDCs containing isoniazid 150 mg + pyrazinamide 500 mg + pyridoxine hydrochloride 15 mg, and 46 patients received FDCs containing isoniazid 150 mg + ethambutol 400 mg + pyridoxine hydrochloride 15 mg. The comparison group (CG) included 146 children who received preventive treatment with single drugs: 111 children received isoniazid and pyrazinamide, and 35 children received isoniazid and ethambutol.Results. When assessing the safety and effectiveness, no statistically significant differences were found when using FDCs and single-drug regimens. 91.9% of children receiving FDCs and 86.3% of children receiving single-drug regimens successfully completed the full course of treatment. When taking FDCs, there was a tendency to lower incidence of adverse events. With the FDC (isoniazid 150 mg + pyrazinamide 500 mg + pyridoxine hydrochloride 15 mg), the proportion of adverse events did not exceed 4.0%. There were no adverse events with the FDC (isoniazid 150 mg + ethambutol 400 mg + pyridoxine hydrochloride 15 mg).Conclusion. Preventive treatment of children with tuberculosis infection with FDC is a modern and effective technology.

The Burden of Bacteriologically Negative TB Diagnosis: A Four-Year Review of Tuberculosis Cases at a Tertiary Facility.

We aimed to investigate the demographic and clinical factors associated with TB mortality in patients managed at a tertiary TB referral center. We conducted a retrospective review of the medical records of 1,933 TB patients seen between January 2017 and December 2020 at the Korle-Bu Teaching Hospital (KBTH) Chest Department in Accra, Ghana. TB mortality was defined as any TB patient who died for any reason during the course of treatment. Multivariable logistic regression was used to estimate adjusted odds ratios with 95% confidence intervals for factors associated with TB mortality. A total of 1,933 patients with TB were registered at the chest clinic over the study period. Males accounted for 1,227 (63.5%), and majority of participants were between 24 and 64 years old. Pulmonary TB (PTB) and extrapulmonary TB (EPTB) cases accounted for 51% and 48.4% of the total TB cases, respectively. A significant proportion (69%) of the patients managed for TB had no bacteriological confirmation of the disease. About 34% of tested TB patients were HIV positive. Mortality among patients was 33.6%. In a multivariable regression model, patients with HIV positive status had over 3-fold increased risk of mortality, compared to those with HIV negative status. TB patients diagnosed empirically had an increased risk of death compared to those with a confirmed diagnosis. The proportion of clinically diagnosed TB was high among the patients seen at the chest clinic. Mortality was high among the patients with HIV/TB coinfection as well as in patients with empirical TB diagnosis.

Herpesvirus infections and HIV (diagnosis and clinical features)

Objective. Epidemiologic analysis of the incidence, prevalence, and structure of various forms of herpesvirus infections (HVI) in patients with and without HIV infection. Material and Methods. The study included 8729 adult patients with HIV-negative status, as well as 937 HIV-infected patients of both sexes aged over of 18 years, with established diagnoses of manifest HVI in 224 cases. The methods used were epidemiological, clinical, laboratory and statistical methods of data processing (Excel, Statistica 10). Results. Among the total number of adult patients, herpes zoster (HZ) was detected in 4446 patients without HIV infection. In 218 patients, a combined course of HVI and HIV infection was detected, of which 203 (22.02%) patients were hospitalized with clinically and laboratory confirmed HVI with moderate to severe course. The frequency of combination of HVI+HIV in relation to the entire group of HVI in hospitalized patients was 1.94%. Among all identified forms of HVI, the most common was HZ – 89.16%, while herpes simplex – 10.71%, Epstein-Barr virus (EBV) infection including infectious mononucleosis – 5.80%, and cytomegalovirus infection (CMVI) – 2.68%. In hospitalized patients with HVI and HIV, HZ was diagnosed in 89.16% of cases, herpes simplex in 6.90%, infectious mononucleosis in 2.46%, and CMVI in 1.48%. Among outpatients with HIV infection, the most common forms of HVI were herpes simplex in 47.61%, EBV infection, including infectious mononucleosis, in 38.09%, and CMVI in 14.29%. Among HIV-infected patients, the main reason for hospitalization was HZ (89.16%). HZ in the presence of HIV infection prevailed among young patients under 40 years of age, and patients over 55 years of age with HZ were significantly more common among patients without HIV infection. Among patients with HZ and HIV infection, severe and generalized forms, cases of meningitis and meningoencephalitis, and damage to 2 dermatomes were significantly more common. The incidence of postherpetic neuralgia and neuropathy among patients with HZ without HIV infection was 14.10% of cases, among patients with HZ and HIV infection in 10.49%. Cases of acute cerebral circulatory failure occurred only among patients of older age groups without HIV infection with the presence of HZ. The most common cause of death among all examined patients with HVI was HZ – 71.43% with complications (encephalitis, pneumonia).

Secondary distribution of HIV self-test kits from males to their female sexual partners in two fishing communities in rural Uganda.

Secondary distribution of HIV self-test kits from females to their male partners has increased HIV testing rates in men but little evidence exists on the potential for HIV self-test kits distribution from males to their female partners. We assessed the acceptability of secondary HIV self-test kits distribution from males to their female sexual partners in a fishing community context. This secondary analysis used data from the PEer-led HIV Self-Testing intervention for MEN (PEST4MEN), a pilot interventional study in Buvuma and Kalangala districts in Uganda. At the baseline visit, in July 2022, data were collected from 400 men aged 15+ years who self-reported a HIV-negative or unknown HIV status. Enrolled men were asked to pick two oral fluid HIV self-test kits from a trained male distributor. At the first follow-up visit, in September 2022, men were asked about the number of kits that they received and if they gave kits to anyone, including to their female sexual partners. We used a modified Poisson regression model to determine the factors independently associated with giving kits to sexual partners. Data were analyzed using STATA version 16.0. Of 361 men interviewed at follow-up, 98.3% (355) received at least one kit; 79.7% (283) received two kits. Of those who received two kits, 64% (181) gave the second kit to anyone else; of these, 74.6% (132/177) gave it to a sexual partner. Being currently married (adjusted prevalence ratio [adj. PR] = 1.39; 95% confidence interval [95%CI]: 1.10, 1.75) and having difficulty in reading text prepared in the local language (adj. PR = 1.26; 95%CI: 1.03, 1.55) were significantly associated with men giving kits to their female sexual partners. Ninety-seven per cent (112/132) of the men reported that they knew their sexual partners' HIV self-test results. Of these, 93.7% (n = 105) reported that their partners were HIV-negative while 6.3% (n = 7) reported that they were HIV-positive. Only 28.6% (n = 2) of the HIV-positive sexual partners were reported to have initiated HIV care. Secondary distribution of HIV self-test kits from males to their female sexual partners is well accepted by women in the fishing communities, suggesting that distribution of kits through men in the fishing communities can help to improve HIV testing uptake among their female sexual partners.

1549. Risk Factors, Risk Perception, and Long-acting PrEP Awareness and Interest among US Women: A National Survey

Abstract Background Cisgender women account for approximately 20% of incident HIV diagnoses in the US. However, only 10% of women who could benefit from HIV pre-exposure prophylaxis (PrEP) have been prescribed PrEP. US women face several challenges that may affect their seeking HIV prevention services, such as lack of PrEP awareness. Understanding these challenges may improve PrEP uptake, especially as innovative PrEP options, such as long-acting (LA) injectable PrEP, become available. This study explored interest in using LA-PrEP by factors that may increase risk of HIV acquisition. Methods Cisgender women were recruited between November 2021 – March 2022 though targeted social media ads on Facebook, Instagram, and Tinder to complete an online, self-administered survey. Eligible participants were cisgender women who were: 18+ years, current US residents, reported penetrative sex in the past six months, and reported an unknown or negative HIV status. The survey included questions on demographics, sexual health and behavior, LA-PrEP awareness, and LA-PrEP interest. Descriptive statistics were calculated using SAS v9.4. Results 1,834 eligible women completed the survey (median age: 28 years (IQR: 25, 33); Geography: South – 65%, West – 21%, Northeast – 7.3%, Midwest – 6.8%; Race: Black, non-Hispanic – 34%, White, non-Hispanic – 25%, Hispanic – 27%, Another race – 14%). Women were more likely to have heard of LA-PrEP if they had reported injection drug use in the past year (71%), had an STI diagnosis (70%) or HIV test (66%) in the past two years, and were currently using contraception (65%). Interest in using LA-PrEP was consistently high; the difference between LA-PrEP awareness and interest was greatest among women with non-private health insurance and those with perceived likelihood of future HIV acquisition. Conclusion Although interest in using LA-PrEP is high among US women, these results demonstrate the large gap between LA-PrEP awareness and interest in using it.

Evaluation of treatment outcomes among adult patients diagnosed with tuberculosis in Ghana: A 10 year retrospective review

ObjectivesThe study determined tuberculosis (TB) treatment outcomes in Southern Ghana from 2012 to 2021. MethodsA retrospective analysis of service data on TB cases was conducted. Treatment success was defined as TB cure or completion of treatment course, whereas unsuccessful outcomes was defined as death, failure of treatment and lost to follow up. Bivariate and multivariate logistic regression was used to determine factors associated with treatment outcomes. ResultsA total of 4106 adult TB cases were reported with a median age of 41 (interquartile range 32-52) years. Of these, 93.1% (n = 3823) were newly diagnosed. The treatment success rate declined from 71.0% in 2012 to 55.7% in 2021 (ktau-b = −0.56, P = 0.0318). Clinically diagnosed TB and extra-pulmonary TB had 7.0% (adjusted prevalence ratio [aPR]: 0.93, 95% confidence interval [CI]: 0.88-1.00) and 24.0% (aPR: 0.76, 95% CI: 0.69-0.84) respectively, less successful treatment outcome compared to pulmonary TB patients. HIV negative status was associated with 22% higher successful treatment outcome compared with being HIV positive (aPR: 1.22, 95% CI: 1.12-1.33). ConclusionTuberculosis treatment success rate declined over the period. There is a need for the TB Control Programme to review the national and sub-national TB data to ascertain poor performing TB treatment sites to identify and address context specific challenges with treatment interventions and system inadequacies to improve treatment success rates.

From Option B+ to Universal "Test and Treat" in Cameroon: Identification and Evaluation of District-level Factors Associated with Retention in Care.

Retaining women in Option B+ services is crucial for eliminating new pediatric HIV infections. However, there are few studies on factors influencing retention at the district level. This study evaluates the factors associated with retention in two health districts of Cameroon. From September 1, 2015, to February 29, 2016, we reviewed the records of pregnant and breastfeeding women initiating Option B+, a lifelong approach to preventing mother-to-child transmission (PMTCT) of HIV, between October 2013 and July 2014. We abstracted sociodemographic and clinical data from registers in 22 health facilities in the Bamenda urban and Kumba rural districts into spreadsheets. Cox regression age-adjusted survival curves were used to compare retention probabilities at 6 and 12 months post-antiretroviral therapy (ART) initiation. Multivariable modified Poisson regressions were run to estimate adjusted relative risk (aRR) of factors associated with retention in PMTCT care at 12 months post-ART initiation. STATA software was used for the analyses. Of the 560 files reviewed, majority, 62.7% (n=351), were above 24 years of age and married, 68.9% (n=386). From the multivariable analysis, enrolling early in antenatal care (ANC) (aRR: 1.50, 95% CIL: 1.17-1.93) and knowing the male partner's HIV-negative status (aRR: 1.16, 95% CI: 1.00-1.34) were significantly associated with higher retention in care, adjusting for maternal age, marital status, and distance from the health facility. By health district, knowing the male partner's HIV-negative status (aRR: 1.30, 95% CI: 1.13-1.50) in the Bamenda urban and enrolling early in ANC (aRR: 2.03, 95% CI" 1.21-3.41) in the Kumba rural district, had significantly higher retention rates after adjusting for the same covariates. Overall, factors influencing retention varied by urban or rural district. Therefore, tailored district-level interventions are needed to enhance early ANC enrollment in the rural and partner HIV status disclosure in the urban districts to improve retention in PMTCT care.
