Abstract
Human immunodeficiency virus type 1 (HIV-1) capsid, which is the target of the antiviral lenacapavir, protects the viral genome and binds multiple host proteins to influence intracellular trafficking, nuclear import, and integration. Previously, we showed that capsid binding to cleavage and polyadenylation specificity factor 6 (CPSF6) in the cytoplasm is competitively inhibited by cyclophilin A (CypA) binding and regulates capsid trafficking, nuclear import, and infection. Here we determined that a capsid mutant with increased CypA binding affinity had significantly reduced nuclear entry and mislocalized integration. However, disruption of CypA binding to the mutant capsid restored nuclear entry, integration, and infection in a CPSF6-dependent manner. Furthermore, relocalization of CypA expression from the cell cytoplasm to the nucleus failed to restore mutant HIV-1 infection. Our results clarify that sequential binding of CypA and CPSF6 to HIV-1 capsid is required for optimal nuclear entry and integration targeting, informing antiretroviral therapies that contain lenacapavir.

Abstract
Background Anogenital warts (AGWs) are a prevalent condition resulting from human papillomavirus (HPV) infection, which is the most frequently encountered sexually transmitted infection (STI) on a global scale. Women who are HIV-positive experience a disproportionately high burden of AGWs compared to other populations. It is imperative to comprehend the epidemiological factors linked to the disease within this particular at-risk population. Objectives The objective of the study was to ascertain the prevalence of AGWs and its demographic and socio-biological epidemiological features among recently diagnosed HIV-positive women (HPW) in Lagos, Nigeria. Materials and methods The research was a descriptive cross-sectional study conducted among a sample of 420 recently diagnosed HPW. The study was conducted at the HIV clinic of a tertiary health institution located in Lagos, Nigeria. The participants clinically diagnosed with AGWs were classified as the study group, while individuals without AGWs were classified as the comparison group. Interviewer-administered pretested questionnaires were utilized to gather pertinent demographic and socio-biological epidemiological data from the participants involved in the study. The data were analyzed using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, USA). Results The prevalence of AGWs among recently diagnosed HPW was found to be 8.5% (34/402). These warts were frequently observed on the vulvar labia (35.3%, 12/34), vaginal walls (14.7%, 5/34), and perianal region (14.7%, 5/34). It is worth noting that over a third of cases (35.3%, 12/34) involved multiple areas within the anogenital region. The diagnosis of AGWs was found to have significant associations with occupation (p=0.005), marital status (p<0.001), and educational status (p=0.028). The majority of HPW diagnosed with AGWs were unemployed (32.4%, 11/34), single (47.1%, 16/34), and did not have tertiary education (94.1%, 32/34). The utilization of oral contraceptive pills (OCPs), smoking, low CD4 count, and high viral load were the significant socio-biological factors associated with the diagnosis of AGWs (p<0.001, respectively). Conclusion The study found that the prevalence of AGW among HPW was 8.5% (34/402). Several epidemiological factors, including occupation, marital status, education, CD4 count, viral load, history of OCP use, and smoking, were found to be significantly associated with the diagnosis of AGW. There is a need to conduct more comprehensive studies to thoroughly assess the impact of these epidemiological factors.

Abstract
The use of tenofovir disoproxil fumarate (TDF) as an antiretroviral agent has been reported to adversely affect both renal tubules and bone health, leading to pathological fractures. While such an effect is largely reversible, substituting TDF with tenofovir alafenamide (TAF) might result in lower rates of adverse events with the preservation of tenofovir effectiveness. We report a case of a 40-year-old lady with HIV infection who had a vertebral fragility fracture secondary to TDF-associated Fanconi syndrome. The syndrome developed four years after TDF cessation and switching to TAF. Other etiologies for decreased bone mass were excluded, and the diagnosis of Fanconi syndrome was established based on her bone mineral density (BMD) and urine parameters. She was treated conservatively with active vitamin D, calcium, and progesterone/estrogen combination, but her phosphate wasting persisted despite switching to TAF; this likely represents a delayed irreversible effect of TDF on the patient's bone remodeling. This case report highlights the chronic sequelae of TDF therapy and the importance of monitoring for and early detection of renal tubulopathy and osteoporotic fractures in this patient population.

Abstract
BACKGROUND Sleep-disordered breathing (SDB) is a known risk factor for hypertension. Despite the well-established link between HIV infection and hypertension, it remains to be determined whether HIV infection modifies the association between SDB and hypertension. SETTING The Multicenter AIDS Cohort Study. METHODS SDB was assessed using in-home polysomnography in 779 men (436 with and 343 without HIV). The apnea-hypopnea index (AHI) based on oxyhemoglobin desaturation threshold of ≥3% or arousal (AHI 3a ) and ≥4% (AHI 4 ) along with oxygen desaturation index (ODI) were used to quantify SDB severity. Hypertension was defined as a blood pressure ≥140/90 mm Hg, use of antihypertensive medication, or self-report of a clinical diagnosis. The associations between HIV, SDB, and hypertension were characterized using multivariable logistic regression. RESULTS The prevalence of hypertension and SDB (AHI 3a ≥ 5 events/hr) was high, with estimates of 53.8% and 82.8%, respectively. Among men without SDB, HIV was independently associated with hypertension, with an adjusted odds ratio (OR) of 3.05 [95% confidence interval (CI): 1.33 to 7.01]. In men without HIV, SDB was associated with hypertension (OR: 2.93; 95% CI: 1.46 to 5.86). No significant increase in the odds of hypertension was noted in men with both HIV and SDB compared with men with either factor alone, with an OR of 3.24 (95% CI: 1.62 to 6.47). These results were consistent across different measures used to define SDB (AHI 3a , AHI 4 , ODI 3 , and ODI 4 ). CONCLUSIONS Predictors of hypertension differed by HIV status. SDB was associated with hypertension in men without HIV, but not in men with HIV. Among men with HIV, SDB did not affect the odds of hypertension.

Abstract
OBJECTIVES We sought to characterize atherosclerotic cardiovascular disease (ASCVD) risk and metrics of cardiovascular health in persons with HIV (PWH) eligible for primary prevention of ASCVD. DESIGN A cross-sectional study of PWH 40 years and older without documented ASCVD who received care at three HIV clinics in San Francisco from 2019 to 2022. METHODS We used ICD-10 codes and electronic health record data to assess ASCVD risk and cardiovascular health, as defined by the American Heart Association's Life's Essential 8 (LE8) metrics for nicotine exposure, BMI, lipids, glucose, and blood pressure (BP). RESULTS Among 2567 PWH eligible for primary prevention of ASCVD, the median age was 55 years, 14% were women, and 95% were on antiretroviral therapy. Seventy-seven percent had undergone complete assessment of ASCVD risk factors, and 50% of these patients had intermediate-high ASCVD risk (≥7.5%). Of those with hypertension, 39% were prescribed an antihypertensive. Among those eligible, 43% were prescribed a statin. The mean LE8 cardiovascular health score [0--100 (best health)] was 55.1 for nicotine exposure, 71.3 for BMI, 70.4 for lipids, 81.2 for blood glucose, 56.0 for BP, with an average score of 66.2 across the five metrics. Patients with Medicare insurance, black patients, and those with sleep apnea and chronic kidney disease had on average lower cardiovascular health scores; patients with undetectable viral loads had higher cardiovascular health scores. CONCLUSION We highlight opportunities for improving primary prevention of ASCVD among PWH, especially in the areas of guideline-based therapy, nicotine exposure, and BP control.

Abstract
OBJECTIVES Studies examining the sociodemographic characteristics associated with human immunodeficiency virus (HIV)-associated dementia (HAD) are lacking, especially in the southern United States. The aim of this study was to describe the characteristics of HAD using South Carolina Alzheimer's Disease Registry data, and examine these characteristics across two time periods. METHODS Data were obtained from the population-based, South Carolina Alzheimer's Disease Registry from 2000-2006 and 2010-2016 (N = 165,487). Crude and multivariable logistic regression models were applied to determine sociodemographic characteristics associated with HAD by time period. RESULTS Younger, Black, Other, men, and urban populations had greater odds of being diagnosed as having HAD in both time periods. For example, compared with individuals aged 85 years and older, individuals aged 18 to 34 had 97 times the odds (adjusted odds ratio 97.0; 95% confidence interval 31.6-297.8) of being diagnosed as having HAD. In 2010-2016, however, nursing facility populations had a greater odds of being diagnosed as having HAD. CONCLUSIONS We found that younger populations (younger than 74 years), communities of color, men, urban populations, and nursing facility populations were more likely to have HAD. Future research should focus on the association between HAD and risk for Alzheimer's disease.

Abstract
Monkeypox (Mpox) is a viral zoonotic disease caused by the Mpox virus, part of the Orthopoxvirus (OPXV) genus, which is a family of double-stranded DNA viruses. It typically presents with lymphadenopathy, fever, and most distinguishably, a rash that extends the cheeks, palms of hands, and soles of feet. This case report describes a unique manifestation of Mpox in a 71-year-old man with a past medical history of HIV, who presented to the emergency department with severe throat pain and oropharyngeal symptoms. Initially, the viral panel and blood cultures were negative, and the patient's condition continued to deteriorate. Under clinical suspicion of Mpox, the patient was tested and found positive. This case report highlights the importance of vigilant surveillance and consideration of Mpox in immunocompromised patients with atypical presentations.

Abstract
OBJECTIVE Depression is prevalent among persons with HIV (PWH) and is associated with poorer adherence and lack of viral load suppression (VLS). When treated for depression, PWH are more likely to stay in HIV care and adhere to medications; however, for many PWH, depression is not adequately diagnosed or treated. We adapted Progression and Transmission of HIV (PATH 3.0), a U.S. agent-based dynamic stochastic simulation model, by incorporating a continuum of depression care and estimating the impact on VLS of an enhanced depression diagnosis and care scenario (EDC). METHODS We compared EDC - whereby every PWH is assessed for depression, gets treatment if diagnosed, and of those, half achieve remission - to a status quo scenario (SQ) on VLS. Based on published findings, assumptions for SQ were: 34.7% depressed, 45% diagnosed, 55.3% treated and 33% of treated achieving remission. Compared to PWH without depression, we assumed the probability of being non-virally suppressed increased by 1.57 times for PWH with depression (PWH-D), and by 0.95 times for PWH with remitted depression. RESULTS There was an average increase of 14.6% (11.5-18.5) in the proportion of PWH-D who achieved VLS in EDC compared to SQ. Among all PWH, there was a 4.7% (3.4-6.0) increase in the proportion who achieved VLS in EDC compared to SQ. CONCLUSIONS Fully diagnosing and adequately treating depression would improve health and quality of life for a substantial proportion of PWH-D and result in a nearly 5% increase in expected rates of VLS in the United States, supporting national prevention goals.

Abstract
Background: Low- and middle-income countries (LMICs) account for nearly 85% of the global cervical cancer burden, yet have the least access to high-performance screening. International guidelines recommend human papillomavirus testing (HPV) as primary screening, yet implementation is inhibited by the cost of HPV testing.Atila AmpFire HPV Assay (AmpFire) is both affordable and easy to use, and offers individual genotyping. The objective of this study was to compare the performance of the AmpFire HPV assay to the Xpert HPV assay in detection of both HPV and clinically significant cervical disease. Methods: We utilized stored cervical specimens from a prospective cohortstudy of women living with human immunodeficiency virus (HIV) in Botswana conducted from May to July 2018. Positive and negative percent agreement was calculated for the AmpFire and Xpert assays, as was detection of high-grade cervical dysplasia. Results : 63 stored cervical specimens haddetectable DNA after thawing and were included in the analysis. The positive percent agreement was 91.2% (95%CI: 76.3-98.1) and negative percent agreement was 79.3% (95% CI: 60.3-92.0). Six cases positive by AmpFire but negative by Xpert were HPV genotypes 35, 52 (n=2), 58, 68, and co-infection with HPV 45 and 68. Both Xpert and AmpFire assays detected HPV in all 10 samples of women who had high-grade cervical dysplasia. Conclusions : The AmpFire HPV assay demonstrated excellent analytic performance in both detection of HPV and clinically significant cervical disease. AmpFire HPV is a promising option to increase access to affordable, type-specific HPV screening for cervical cancer in LMICs.

Abstract
OBJECTIVES Assess the impact of pre-treatment high-frequency and low-frequency drug-resistant HIV variants on long-term outcomes of first-line efavirenz-based antiretroviral therapy (ART). DESIGN Prospective observational study. METHODS Participants' pre-treatment plasma RNA had two sections of HIV pol encoding reverse transcriptase sequenced (Illumina, MiSeq) using unique molecular identifiers to detect wild-type (pre-treatment drug-resistant variants less than 1% of viral quasispecies), low-frequency (1-9%) or high-frequency drug-resistant variants (10-100%). Associations between pre-treatment drug resistance and virologic outcomes over 24 months of efavirenz-based ART were assessed for the number and frequency of mutations by drug class and other resistance parameters. RESULTS Virologic failure was detected in 30 of 352 (9%) and pre-treatment drug-resistant variants were detected in the viral quasispecies of 31 of 352 (9%) participants prescribed efavirenz-based ART. Survival analyses revealed statistically significant associations between pre-treatment drug resistance at low (P < 0.0001) and high (P < 0.001) frequencies, at oligonucleotide ligation assay (OLA) (P < 0.00001) and non-OLA (P < 0.01) codons, to a single-antiretroviral class (P < 0.00001), and a shorter time to virologic failure of efavirenz-based ART. Regression analyses detected independent effects across resistance categories, including both low-frequency (P < 0.01) and high-frequency (P < 0.001) drug-resistant variants. CONCLUSION We observed that pre-treatment HIV drug resistance detected at low frequencies increased the risk of virologic failure over 24 months of efavirenz-based ART, but that most failures, regardless of drug-resistant variants' frequencies, were detected within a year of ART initiation. These observations suggest that when efavirenz-based ART is prescribed, screening for pre-treatment drug resistance by an assay capable of detecting low-frequency variants, including OLA, may guide clinicians to prescribe more effective ART.

Abstract
BACKGROUND Rapid antiretroviral therapy (ART) initiation, in which people living with HIV start ART within days of diagnosis, is a key component of the US Ending the HIV Epidemic initiative. SETTING The Memphis Metropolitan Statistical Area ranked fourth in the United States for the highest HIV incidence per 100,000 population in 2018. Rapid ART programs are limited in the Memphis Metropolitan Statistical Area, and our objective was to identify local implementation barriers. METHODS We conducted participatory process mapping and in-depth interviews to detail steps between HIV testing at the municipal health department's Sexually Transmitted Infections Clinic and ART prescription from a nearby high-volume Ryan White-funded HIV Clinic. RESULTS Process mapping identified 4 modifiable, rate-limiting rapid ART barriers: (1) requiring laboratory-based confirmatory HIV results, (2) eligibility documentation requirements for Ryan White-funded services, (3) insufficient HIV Clinic medical provider availability, and (4) variability in ART initiation timing among HIV Clinic providers. Staff at both sites highlighted suboptimal communication and sense of shared management between facilities, limited resources to address important social determinants of health, and lack of Medicaid expansion in Tennessee as key barriers. In-depth interview themes negatively affecting rapid ART initiation included clinic burden; provider knowledge, attitudes, and beliefs; and client psychosocial needs. CONCLUSIONS Our preimplementation work identified modifiable and systemic barriers to systems flow and patient-level outcomes. This work will inform the design and implementation of a locally relevant rapid ART program in Memphis, a community disproportionately affected by the HIV epidemic.

Abstract
INTRODUCTION Early systemic and central nervous system viral replication and inflammation may affect brain integrity in people with HIV, leading to chronic cognitive symptoms not fully reversed by antiretroviral therapy (ART). This study examined associations between cognitive performance and markers of CNS injury associated with acute HIV infection and ART. METHODS HIV-infected MSM and transgender women (average age: 27 years and education: 13 years) enrolled within 100 days from the estimated date of detectable infection (EDDI). A cognitive performance (NP) protocol was administered at enrollment (before ART initiation) and every 24 weeks until week 192. An overall index of cognitive performance (NPZ) was created using local normative data. Blood (n = 87) and cerebrospinal fluid (CSF; n = 29) biomarkers of inflammation and neuronal injury were examined before ART initiation. Regression analyses assessed relationships between time since EDDI, pre-ART biomarkers, and NPZ. RESULTS Adjusting for multiple comparisons, shorter time since EDDI was associated with higher pre-ART VL and multiple biomarkers in plasma and CSF. NPZ scores were within the normative range at baseline (NPZ = 0.52) and at each follow-up visit, with a modest increase through week 192. Plasma or CSF biomarkers were not correlated with NP scores at baseline or after ART. CONCLUSIONS Biomarkers of CNS inflammation, immune activation, and neuronal injury peak early and then decline during acute HIV infection, confirming and extending results of other studies. Neither plasma nor CSF biomarkers during acute infection corresponded to NP scores before or after sustained ART in this cohort with few psychosocial risk factors for cognitive impairment.

Abstract
Over the past few years, the attention of the whole world has been riveted to the emergence of new dangerous strains of viruses, among which a special place is occupied by coronaviruses that have overcome the interspecies barrier in the past 20 years: SARS viruses (SARS), Middle East respiratory syndrome (MERS), as well as a new coronavirus infection (SARS-CoV-2), which caused the largest pandemic since the Spanish flu in 1918. Coronaviruses are members of a class of enveloped viruses that have a lipoprotein envelope. This class also includes such serious pathogens as human immunodeficiency virus (HIV), hepatitis, Ebola virus, influenza, etc. Despite significant differences in the clinical picture of the course of disease caused by enveloped viruses, they themselves have a number of characteristic features, which determine their commonality. Regardless of the way of penetration into the cell—by endocytosis or direct fusion with the cell membrane—enveloped viruses are characterized by the following stages of interaction with the target cell: binding to receptors on the cell surface, interaction of the surface glycoproteins of the virus with the membrane structures of the infected cell, fusion of the lipid envelope of the virion with plasma or endosomal membrane, destruction of the protein capsid and its dissociation from the viral nucleoprotein. Subsequently, within the infected cell, the newly synthesized viral proteins must self-assemble on various membrane structures to form a progeny virion. Thus, both the initial stages of viral infection and the assembly and release of new viral particles are associated with the activity of viral proteins in relation to the cell membrane and its organelles. This review is devoted to the analysis of physicochemical mechanisms of functioning of the main structural proteins of a number of enveloped viruses in order to identify possible strategies for the membrane activity of such proteins at various stages of viral infection of the cell.

Abstract
BACKGROUND Multiple previous studies have identified a detrimental effect of pediatric HIV on cognitive function. Socioeconomic status (SES) is one of the strongest predictors of cognitive performance and may affect the relationship between HIV and cognition. METHODS As part of the ongoing HIV-Associated Neurocognitive Disorders in Zambia (HANDZ) study, a prospective cohort study, we recruited 208 participants with HIV and 208 HIV-exposed uninfected controls, all aged 8-17 years. A standardized questionnaire was administered to assess SES, and all participants had comprehensive neuropsychological testing. An NPZ8 score was derived as a summary measure of cognitive function. Logistic regression and linear regression were used to model the relationship between SES and cognitive function, and mediation analysis was used to identify specific pathways by which SES may affect cognition. RESULTS Children with HIV performed significantly worse on a composite measure of cognitive function (NPZ8 score -0.19 vs. 0.22, P < 0.001) and were more likely to have cognitive impairment (33% vs. 19%, P = 0.001). Higher SES was associated with reduced risk of cognitive impairment (odds ratio 0.8, 95% confidence interval: 0.75-0.92, P < 0.001) in both groups, with similar effects in children with HIV and HIV-exposed uninfected groups. SES was more strongly correlated with NPZ8 score in children with HIV than in uninfected controls (Pearson's R 0.39 vs. 0.28), but predicted NPZ8 in both groups. Mediation analysis suggested that the effect of SES on cognition was most strongly mediated through malnutrition. CONCLUSIONS Cognitive function is strongly correlated with SES in children with HIV, suggesting a synergistic effect of HIV and poverty on cognitive function.

Abstract
BACKGROUND Depression is frequent among youth living with HIV (YLWH). Studies suggest that manualized treatment guided by symptom measurement is more efficacious than usual care. SETTING This study evaluated manualized, measurement-guided depression treatment among YLWH, aged 12-24 years at 13 US sites of the International Maternal Pediatric Adolescent AIDS Clinical Trials Network. METHODS Using restricted randomization, sites were assigned to either a 24-week, combination cognitive behavioral therapy and medication management algorithm (COMB-R) tailored for YLWH or to enhanced standard of care, which provided standard psychotherapy and medication management. Eligibility included diagnosis of nonpsychotic depression and current depressive symptoms. Arm comparisons used t tests on site-level means. RESULTS Thirteen sites enrolled 156 YLWH, with a median of 13 participants per site (range 2-16). At baseline, there were no significant differences between arms on demographic factors, severity of depression, or HIV status. The average site-level participant characteristics were as follows: mean age of 21 years, 45% male, 61% Black, and 53% acquired HIV through perinatal transmission. At week 24, youth at COMB-R sites, compared with enhanced standard of care sites, reported significantly fewer depressive symptoms on the Quick Inventory for Depression Symptomatology Self-Report (QIDS-SR score 6.7 vs. 10.6, P = 0.01) and a greater proportion in remission (QIDS-SR score ≤ 5; 47.9% vs. 17.0%, P = 0.01). The site mean HIV viral load and CD4 T-cell level were not significantly different between arms at week 24. CONCLUSIONS A manualized, measurement-guided psychotherapy and medication management algorithm tailored for YLWH significantly reduced depressive symptoms compared with standard care at HIV clinics.

Abstract
Nocardiosis is an opportunistic infection that most commonly affects immunocompromised patients, with clinical presentations ranging from localized to disseminated disease. In the United States, the reported incidence is approximately 500 to 1,000 cases per year, with an observed male-to-female predominance of 3:1. We present the case of a 37-year-old male with a past medical history of malaria who presented with watery, non-bloody diarrhea for four days associated with a fever for two weeks. The human immunodeficiency virus (HIV) was positive in the emergency room before admission. Computerized tomography (CT) of the chest with contrast revealed an irregular pleural base mass in the right lower lobe with several small air foci. CT of the abdomen and pelvis revealed the right pleural base lung mass to be adherent to the diaphragm, as well as mild splenomegaly. The cluster of differentiation 4 (CD4) count was 9 cells/mm3. An acid-fast bacilli (AFB) sputum culture was positive for Nocardia farcinica. Trimethoprim-sulfamethoxazole was started for a Nocardia farcinica pulmonary infection, in addition to antiretroviral therapy. The patient was strongly encouraged to follow-up at the outpatient department.

Abstract
ABSTRACT In this large online survey of primarily men who have sex with men, those who used preexposure prophylaxis reported greater sexual satisfaction than did nonusers, including sexual sensations, sexual presence/awareness, and sexual exchange. Person-centered care and messaging may require acknowledging that some people use preexposure prophylaxis for reasons beyond HIV prevention.

Abstract
BACKGROUND HIV prevention is the primary goal of preexposure prophylaxis (PrEP); however, ancillary benefits may exist, including PrEP as an entry point to primary care. OBJECTIVE To explore PrEP users' perspectives on how PrEP use relates to broader engagement in health care. DESIGN In-depth qualitative interviews. PARTICIPANTS We recruited PrEP users aged 18 years or older from a social media group for people interested in PrEP information and a Boston community health center specializing in health care for sexual and gender minorities. APPROACH Inductive content analysis to identify emergent themes. KEY RESULTS All 25 participants were men who have sex with men, whose mean age was 34 years, and 84% were White. Three major themes emerged: (1) accessing PrEP was a strong motivator for initial and continued engagement in health care, which for some evolved over time into accessing comprehensive primary care; (2) provider awareness and attitudes about PrEP influenced participants' ongoing engagement in health care; and (3) PrEP engendered a positive sense of control over users' personal health, giving them agency in reducing their risk of HIV and engaging in other aspects of their health. Quarterly PrEP visits helped participants establish and maintain a relationship with a primary care provider, access non-HIV-related care services, and feel empowered to keep themselves healthy. CONCLUSIONS The benefits of PrEP extend beyond HIV prevention to broader engagement in health care, including new relationships with primary care providers and use of other preventive health care services. To maximize those benefits, efforts are needed to ensure that providers are aware, nonjudgmental, and supportive of PrEP use.

Abstract
BACKGROUND A key challenge of HIV surveillance-based HIV care reengagement is locating people living with HIV (PLWH) who seem to be out of care to reengage them in care. Providing reengagement services to PLWH diagnosed with a sexually transmitted disease (STD)-individuals who are in jurisdiction and connected to the health care system-could be an efficient means of promoting HIV treatment and reducing HIV transmission. METHODS Early and late syphilis (ES/LS) and gonorrhea (GC) cases diagnosed in 2016 and 2017 in Louisiana, Michigan, Mississippi, Oregon, Rhode Island, and Texas were matched to each state's HIV surveillance data to determine the proportion of PLWH with these infections who (1) did not have evidence of a CD4 count or viral load in the prior ≥13 months (out of care) or (2) had a viral load ≥1500 copies/mL on their most recent HIV RNA test before STD diagnosis (viremic). RESULTS Previously diagnosed HIV infection was common among persons diagnosed with ES (n = 6942; 39%), LS (n = 4329; 27%), and GC (n = 9509; 6%). Among these ES, LS, and GC cases, 26% (n = 1543), 33% (n = 1113), and 29% (n = 2391) were out of HIV medical care or viremic at the time of STD diagnosis. CONCLUSIONS A large proportion of STD cases with prior HIV diagnosis are out of care or viremic. Integrating relinkage to care activities into STD partner services and/or the use of matching STD and HIV data systems to prioritize data to care activities could be an efficient means for relinking patients to care and promoting viral suppression.

Abstract
BACKGROUND The Department of Veterans Affairs cares for the largest population of patients with HIV of any healthcare system in the United States. Screening for anal dysplasia/cancer is recommended for all veterans with HIV. Exams are invasive, burdensome, and resource intensive. We currently lack markers of disease to tailor screening. OBJECTIVE The purpose of this study was to establish the prevalence of advanced anal disease (high-grade dysplasia and anal cancer) and to determine whether CD4/CD8 ratio correlates with risk. DESIGN This was a retrospective regional cohort study of veterans with HIV. SETTINGS The study was conducted at eight medical centers between 2001 and 2019. PATIENTS Patients with advanced disease were compared with patients with nonadvanced anal pathology. MAIN OUTCOME MEASURES Logistic regression modeling was used to estimate adjusted odds of disease as a function of CD4/CD8. Lowest (nadir) CD4/CD8 and nearest CD4/CD8 ratio in each cohort were evaluated. RESULTS A total of 2267 veterans were included. Fifteen percent had anal pathology (112 with advanced disease (37 cancer and 75 high-grade), 222 with nonadvanced disease). Nadir and nearest ratio were lower in patients with advanced disease versus nonadvanced (0.24 vs 0.45 (p < 0.001) and 0.50 vs 0.88 (p < 0.001)). In adjusted models, a 1-unit increase in nadir or nearest ratio conferred decreased risk of advanced disease (OR = 0.19 (95% CI, 0.07-0.53); p < 0.001; OR = 0.22 (95% CI, 0.12-0.43); p < 0.001). Using a minimum sensitivity analysis, a cutoff nadir ratio of 0.42 or nearest ratio of 0.76 could be used to risk stratify. LIMITATIONS This was a retrospective analysis with a low screening rate. CONCLUSIONS In a regional cohort of veterans with HIV, 15% were formally assessed for anal dysplasia. Advanced anal disease was present in 33% of those screened, 5% of the HIV-positive population. A strong predictor of advanced disease in this cohort is the CD4/CD8 ratio, which is a promising marker to stratify screening practices. Risk stratification using CD4/CD8 has the potential to decrease burdensome invasive examinations for low-risk patients and to intensify examinations for those at high risk.

PREVALENCIA DE DISPLASIA ANAL DE ALTO GRADO Y CNCER ANAL EN VETERANOS QUE VIVEN CON EL VIH Y LA RELACIN CD / CD COMO MARCADOR DE MAYOR RIESGO UN ESTUDIO DE COHORTE REGIONAL RETROSPECTIVE ANTECEDENTES:El Departamento de Asuntos de Veteranos atiende a la población más grande de pacientes con el virus de inmunodeficiencia humana (VIH) de cualquier sistema de salud en los Estados Unidos. Se recomienda la detección de displasia / cáncer anal para todos los veteranos con VIH. Los exámenes son invasivos, onerosos y requieren muchos recursos. Actualmente carecemos de marcadores de enfermedad para adaptar la detección.OBJETIVO:Establecer la prevalencia de enfermedad anal avanzada (displasia de alto grado y cáncer anal) y determinar si la relación CD4 / CD8 se correlaciona con el riesgo.DISEÑO:Estudio de cohorte regional retrospectivo de veteranos con VIH.AJUSTE:Ocho centros médicos entre 2001-2019.PACIENTES:Se comparó a pacientes con enfermedad avanzada con pacientes con patología anal no avanzada.PRINCIPALES MEDIDAS DE RESULTADO:Se utilizó un modelo de regresión logística para estimar las probabilidades ajustadas de enfermedad en función de CD4 / CD8. Se evaluó la relación CD4 / CD8 más baja (nadir) y la relación CD4 / CD8 más cercana en cada cohorte.RESULTADOS:Se incluyeron un total de 2267 veteranos. El 15% tenía patología anal (112 enfermedad avanzada (37 cáncer, 75 de alto grado), 222 enfermedad no avanzada). El nadir y el cociente más cercano fueron menores en los pacientes con enfermedad avanzada frente a los no avanzados (0,24 frente a 0,45 (p <0,001) y 0,50 frente a 0,88 (p <0,001)), respectivamente. En modelos ajustados, el aumento de una unidad en el nadir o el cociente más cercano confirió una disminución del riesgo de enfermedad avanzada (OR 0,19 (IC del 95%: 0,07, 0,53, p <0,001)) y (OR 0,22 (IC del 95%: 0,12, 0,43, p <0,001))), respectivamente. Utilizando un análisis de sensibilidad mínima, se podría utilizar un cociente del nadir de corte de 0,42 o el cociente más cercano de 0,76 para estratificar el riesgo.LIMITACIONES:Análisis retrospectivo con una tasa de detección baja.CONCLUSIONES:En una cohorte regional de veteranos con VIH, el 15% fueron evaluados formalmente por displasia anal. La enfermedad anal avanzada estuvo presente en el 33% de los examinados, el 5% de la población VIH +. Un fuerte predictor de enfermedad avanzada en esta cohorte es la relación CD4 / CD8, que es un marcador prometedor para estratificar las prácticas de detección. La estratificación del riesgo usando CD4 / CD8 tiene el potencial de disminuir los exámenes invasivos onerosos para los pacientes de bajo riesgo e intensificar los exámenes para los de alto riesgo.

Abstract
A 37-year-old man with a history of renal transplantation in 2013 due to focal segmental glomerulosclerosis presented to the emergency room with a 2-week history of fever, chills, anorexia, weight loss, abdominal pain, diarrhea, and a new asymptomatic lesion on the right side of the neck. The patient worked as a truck driver and frequently traveled to Wisconsin; he had not traveled internationally in the past year. He lived with his brother who had a pet cat. He was compliant with his anti-rejection medication regimen, which included mycophenolate mofetil, tacrolimus, and prednisone. Physical examination of the neck revealed an 8-mm exophytic, friable, red papule with overlying blood crusts (Figure 1). The remainder of the mucocutaneous examination was unremarkable, and there was no palpable lymphadenopathy. The patient was started on empiric intravenous cefepime and metronidazole and admitted to the hospital for further management. A punch biopsy of the lesion was performed.

Abstract
Human immunodeficiency virus (HIV) supresses immune system, primarily cell-mediated immunity. Cluster of differentiation 4 (CD4) cell count, viral load, and oral lesions are the most important laboratory parameters to evaluate the evolution of acquired immunodeficiency syndrome. The present study aims to determine the incidence of HIV-related oral lesions with CD4 cell count and viral load in Yunnan, China.A cross-sectional study was conducted from December 2007 to December 2009, in 1812 HIV positive patients from Department of Infectious Diseases in Kunming Third People's Hospital. CD4, CD8, and viral load data were collected and analyzed statistically using SPSS 11.3.Out of 1812 HIV positive patients, 929 (51.27%) were associated with 1 or more oral lesions. The most common oral lesions observed were Candida Pseudomembranous (13.75%), Candida erythematous (10.93%), Oral hairy leukoplakia (7.95%), Aphthous ulcer (6.18%), Herpes simplex infection (5.58%). In most patients with oral lesions, the CD4 cell count was < 200/μL. The incidence of oral lesions was lower when CD4 count was > 200/μL and with undetectable (P < .01) HIV viral load. Almost no oral lesions was observed when CD4 count > 500/μL (P < .01). With highly active antiretroviral therapy, reduction in HIV-related oral lesions was observed especially in Candida erythematous, Candida Pseudomembranous, Oral hairy leukoplakia, and Aphthous ulcer.The higher incidence of oral lesions with lower CD4 count (<200/μL) in HIV-infected patients indicated importance of CD4 cell count in identifying disease progression.

Abstract
This study described the prevalence of adverse pregnancy outcomes (APOs) in Chinese HIV-infected pregnant women, and examined the relationship between maternal HIV infection /HIV-related factors and APOs.This prospective cohort study was carried out among 483 HIV-infected pregnant women and 966 HIV-uninfected pregnant women. The HIV-infected and HIV-uninfected women were enrolled from midwifery hospitals in Hunan province between October 2014 and September 2017. All data were extracted in a standard structured form, including maternal characteristics, HIV infection status, HIV-related factors and their pregnancy outcomes. APOs were assessed by maternal HIV infection status and HIV-related factors using logistic regression analysis.The incidences of stillbirth (3.9% vs 1.1%), preterm birth (PTB) (8.9% vs 3.7%), low birth weight (LBW) (12.2% vs 3.1%) and small for gestational age (SGA) (21.3% vs 7.0%) were higher in HIV-infected women than HIV-uninfected women, with adjusted ORs of 2.77 (95%CI: 1.24-6.17), 2.37 (95%CI: 1.44-3.89), 4.20 (95%CI: 2.59-6.82) and 3.26 (95%CI: 3.26-4.64), respectively. No differences were found in neonatal asphyxia or birth defects between HIV-infected and HIV-uninfected groups, with adjusted ORs of 1.12 (95%CI: 0.37-3.43) and 1.10 (95%CI: 0.51-2.39), respectively. Among HIV-infected pregnant women, different antiretroviral (ARV) regimens were significantly associated with stillbirths, but not PTB, LBW or SGA. Compared with untreated HIV infection (10.1%), both mono/dual therapy and HAART were associated with a reduced risk of stillbirths (2.0% and 3.2%, respectively), with an AOR of 0.19 (95%CI: 0.04-0.92) and 0.31 (95%CI: 0.11-0.85), respectively. Initial time of ARV drugs use and HIV infection status of the sexual partner were not associated with maternal APOs.The findings of this study indicated that maternal HIV infection was associated with significantly increased risks of stillbirth, PTB, LBW and SGA, but not neonatal asphyxia or birth defects. On the condition that most HIV-infected pregnant women started ARV therapy in or after the second trimester, both mono/dual therapy and HAART had a protective effect on stillbirth compared with untreated HIV infection. As some important confounders were not effectively controlled and the specific regimens of HAART were not analyzed, the above findings may have certain bias.

Abstract
Human immunodeficiency virus (HIV) disclosure is a prerequisite to get access to antiretroviral therapy (ART) and social support. Increased disclosure of HIV status has been shown to reduce mother-to-child transmission and high-risk sexual behaviors. Limited studies were conducted to get an insight into HIV disclosure among people living with HIV/acquired immune deficiency syndrome (AIDS) (PLWHA) in Liangshan.Our study aimed to investigate the status and associated characteristics of HIV disclosure among PLWHA in Liangshan.We conducted a cross-sectional study using a stratified, convenience sampling method from August to December in 2017. All of the participants were from Liangshan, a typical impoverished mountainous area which also has a long history of drug production and drug trade. Each participant completed a structured questionnaire including HIV disclosure status, demographic and HIV-related characteristics, social support, and perceived HIV-related stigma. We performed a binary regression analysis to detect associated characteristics of HIV disclosure among PLWHA in Liangshan.A final sample size of 318 participants was included in this study. The overall prevalence of HIV disclosure was 83.6% (266/318). In binary logistic regression analysis, PLWHA who had higher educational levels, and got infected by sexual transmission were less likely to disclose their HIV status (both P < .05). HIV nondisclosure was correlated with a higher level of perceived HIV-related stigma (P < .01).The prevalence of HIV disclosure was relatively low in Liangshan. Healthcare workers are suggested to conduct more counseling and education to promote safe sexual behaviors and reduce perceived stigma among PLWHA, then enhance HIV serostatus disclosure.

Abstract
Primary gastrointestinal lymphoma is a rare neoplasm that accounts for less than 5% of all gastrointestinal malignancies. We present a case of a 37-year-old woman positive for human immunodeficiency virus who presented with abdominal pain and vomiting for three months. She underwent endoscopic biopsy and was found to have high-grade diffuse large B-cell lymphoma in the jejunum. This report discusses her treatments and includes a brief literature review highlighting the rarity of this entity, the etiological agents implicated in its pathogenesis, and the lack of specific guidelines for treatment.

Abstract
Among human immunodeficiency virus-positive women in Botswana on the recommended first-line antiretroviral therapy regimen, tenofovir-emtricitabine-efavirenz, initiated within the first or early second trimester, we found no increased risk of stillbirth, neonatal death, preterm/very preterm delivery, or the infant being born small or very small for gestational age. Treatment with tenofovir-emtricitabine-efavirenz <1 year before conception increased the risk of preterm delivery slightly over late-second-trimester treatment initiation (adjusted risk ratio, 1.33 [95% confidence interval, 1.04-1.70]).

Abstract
Although significant progress has been made, the latest data from low- and middle-income countries show substantial gaps in reaching the third "90%" (viral suppression) of the UNAIDS 90-90-90 goals, especially among vulnerable and key populations. This article discusses critical gaps and promising, evidence-based solutions. There is no simple and/or single approach to achieve the last 90%. This will require multifaceted, scalable strategies that engage people living with human immunodeficiency virus, motivate long-term treatment adherence, and are community-entrenched and ‑supported, cost-effective, and tailored to a wide range of global communities.

Abstract
Antiretroviral medications are the mainstay of human immunodeficiency virus (HIV) therapy and some have been in use for over 20 years. To date, there have been no reported cases of antiretroviral therapy (ART) induced drug-induced lupus erythematosus (DILE). We present a case of a 35-year-old woman who received a combination of emtricitabine, rilpivirine, and tenofovir disoproxil fumarate for HIV treatment. Three years later, she developed an extensive rash and polyarthralgia in her extremities with laboratory findings significant for positive antinuclear antibody (ANA), anti-double stranded deoxyribonucleic acid (DNA) antibody (anti-dsDNA), and anti-histone antibody titers. Her systemic symptoms and rash improved with ART discontinuation. She was later restarted on her original ART due to difficulty in tolerating a different combination therapy. A few months after restarting ART, she developed new dermatologic symptoms, worsening arthralgias, tenderness of the metacarpophalangeal and proximal interphalangeal joints of the hand, and an increase in anti-dsDNA titers to 286 IU/ml. ART was then discontinued, which led to complete resolution of her symptoms and her anti-dsDNA decreased significantly. She had no further recurrence of symptoms. Awareness of the possibility of ART-induced DILE in the right clinical setting would prompt early recognition and management of this condition.

Abstract
Ritonavir is commonly used in low doses to boost plasma levels of protease inhibitors in patients with human immunodeficiency virus (HIV) infections. It is also a potent inhibitor of cytochrome P450. We present a 50-year-old African American male with past medical history of HIV on highly active antiretroviral therapy (HAART), which also included ritonavir and long standing asthma that has been treated with inhaled fluticasone, who presented with back pain. He had central obesity, prominent abdominal striae and wasted extremities on physical examination. Laboratory tests showed low morning serum cortisol and suboptimal cosyntropin test consistent with adrenal insufficiency. Computed tomography (CT) of the spine showed a fracture of inferior endplate of the lumbar (L3) vertebra. The cause of osteoporosis is believed to be iatrogenic Cushing syndrome caused by enhanced levels of inhaled fluticasone effects secondary to inhibition of cytochrome P450. The patient was managed surgically and fluticasone was discontinued.

Abstract
To describe the clinical manifestations, treatments, prognosis, and prevalence of autoimmune diseases (ADs) in human immunodeficiency virus (HIV)-infected patients.All HIV-infected patients managed in the Infectious Diseases Department of the Lyon University Hospitals, France, between January 2003 and December 2013 and presenting an AD were retrospectively included.Thirty-six ADs were found among 5186 HIV-infected patients which represents a prevalence of 0.69% including immune thrombocytopenic purpura (n = 15), inflammatory myositis (IM) (n = 4), sarcoidosis (n = 4), Guillain-Barré syndrome (GBS) (n = 4), myasthenia gravis (n = 2), Graves' disease (n = 2), and 1 case of each following conditions: systemic lupus erythematosus, rheumatoid arthritis, autoimmune hepatitis, Hashimoto thyroiditis and autoimmune hemolytic anemia. One patient presented 2 ADs. Thirty patients were known to be HIV-infected when they developed an AD. The AD preceded HIV infection in 2 patients. GBS and HIV infection were diagnosed simultaneously in 3 cases. At AD diagnosis, CD4 T lymphocytes count were higher than 350/mm in 63% of patients, between 200 and 350/mm in 19% and less than 200/mm in 19%. Twenty patients benefited from immunosuppressant treatments, with a good tolerance.ADs during HIV infection are uncommon in this large French cohort. Immune thrombocytopenic purpura, sarcoidosis, IM, and GBS appear to be more frequent than in the general population. Immunosuppressant treatments seem to be effective and well tolerated.

Abstract
BACKGROUND Non-tuberculous mycobacteria (NTM) are increasingly reported worldwide associated with human disease. Defining the significance of NTM in settings with endemic tuberculosis (TB) requires the discrimination of NTM from TB in suspect patients. Correct and timely identification of NTM will impact both therapy and epidemiology of TB and TB-like diseases. The present study aimed at determining the frequency and diversity of NTM among TB suspects in northeastern Tanzania. METHODS A cross-sectional study was conducted between November 2012 through January 2013. Seven hundred and forty-four sputum samples were collected from 372 TB suspects. Detection was done by using phenotypic, GenoType(®) Mycobacterium CM/AS kits, 16S rRNA and hsp65 gene sequencing for identification of isolates not identified by Hain kits. Binary regression model was used to analyse the predictors of NTM detection. RESULTS The prevalence of NTM was 9.7% of the mycobacterial isolates. Out of 36 patients with confirmed NTM infection, 12 were HIV infected with HIV being a significant predictor of NTM detection (P < 0.001). Co-infection with Mycobacterium tuberculosis (M. tb) was found in five patients. Twenty-eight NTM isolates were identified using GenoType(®) Mycobacterium CM/AS and eight isolates could not be identified. Identified species included M. gordonae and M. interjectum 6 (16.7%), M. intracelullare 4 (11.1%), M. avium spp. and M. fortuitum 2 (5.5%), M. kansasii, M. lentiflavum, M. simiae, M. celatum, M. marinum 1 (2.8%) each. Of isolates not identified to subspecies level, we identified M. kumamotonense (2), M. intracellulare/kansasii, M. intermedium/triplex, M. acapulcensis/flavescens, M. stomatepiae, M. colombiense and M. terrae complex (1) each using 16S rRNA sequencing. Additionally, hsp65 gene sequencing identified M. kumamotonense, M. scrofulaceum/M. avium, M. avium, M. flavescens/novocastrense, M. kumamotonense/hiberniae, M. lentiflavum, M. colombiense/M. avium and M. kumamotonense/terrae/hiberniae (1) each. Results of the 16S rRNA and hsp65 gene sequencing were concordant in three and discordant in five isolates not identified by GenoType(®) Mycobacterium CM/AS. CONCLUSION NTM infections may play a vital role in causing lung disease and impact management of TB in endemic settings. GenoType(®) Mycobacterium CM/AS represents a useful tool to identify clinical NTM infections. However, 16S rRNA gene sequencing should be thought for confirmatory diagnosis of the clinical isolates. Due to the complexity and inconsistence of NTM identification, we recommend diagnosis of NTM infections be centralized by strengthening and setting up quality national and regional infrastructure.

Abstract
The Centers for Disease Control and Prevention (CDC) recommends annual HIV screening for persons at high risk for HIV infection. We assessed the testing history and factors associated with recent testing (tested in the last 12 months) among persons at high risk for HIV infection. We analyzed 2006-2010 National Survey of Family Growth data and classified respondents aged 15-44 who reported a sexual or drug-use risk behavior in the past year as 'high-risk'. Logistic regression models estimated prevalence ratios assessing the association between demographic and health-related factors and having been recently tested for HIV compared with never been tested. Among high-risk men, 29.3% had recently tested for HIV, 30.7% tested more than 12 months ago, and 40.0% had never been tested. Among high-risk women, 38.0% had recently tested, 36.9% tested more than 12 months ago, and 26.1% had never been tested. Compared with men who were aged 15-19, white, heterosexual, and had not recently visited a doctor, men who were aged 40-44, black/African American, homosexual/gay or bisexual, and had visited a doctor in the past year were more likely to have recently tested. Compared with women who were white, had not recently visited a doctor, and had never been pregnant, women more likely to have recently tested were black/African American, had visited a doctor in the past year, and had been pregnant. Approximately two-thirds of high-risk men and women had not been recently tested for HIV. CDC recommendations for annual screening are not being implemented for the majority of persons at risk.

Abstract
IMPORTANCE Age-related hearing loss affects quality of life. Data on hearing loss among aging human immunodeficiency virus-seropositive (HIV+) adults are limited. OBJECTIVE To evaluate pure-tone hearing thresholds among HIV+ and HIV-seronegative (HIV-) adults and to determine whether HIV disease variables and antiretroviral therapy are associated with pure-tone threshold levels. DESIGN, SETTING, AND PARTICIPANTS A total of 262 men (117 HIV+) from the Baltimore, Maryland/Washington, DC, site of the Multicenter AIDS Cohort Study and 134 women (105 HIV+) from the Washington, DC, site of the Women's Interagency HIV Study participated. Pure-tone air conduction thresholds were collected in a sound-treated room for each ear at frequencies from 250 through 8000 Hz. Linear mixed regression models tested the effect of HIV on hearing after adjustment for age, sex, race, and noise exposure history. MAIN OUTCOMES AND MEASURES Low-frequency pure-tone average (LPTA) at 250, 500, 1000, and 2000 Hz and high-frequency PTA (HPTA) at 3000, 4000, 6000, and 8000 Hz. Differential HIV effects for LPTA and HPTA and better/worse ear were also examined. CD4⁺ and CD8⁺ T-cell counts, log10 plasma HIV RNA concentrations, receipt of AIDS diagnosis, and cumulative duration of antiretroviral therapy were included in the models for HIV+ participants only. RESULTS HPTA and LPTA were significantly higher (18%: estimated ratio, 1.18 [95% CI, 1.02-1.36]; P = .02; and 12%: estimated ratio, 1.12 [95% CI, 1.00-1.26]; P = .05, respectively) for HIV+ participants compared with HIV- participants for the better ear. The direction of the effect was consistent across both the better and worse ears. There were no significant associations between HIV disease variables or treatment variables and LPTA or HPTA. CONCLUSIONS AND RELEVANCE The HIV+ adults had significantly poorer lower-frequency and higher-frequency hearing than HIV- adults. High-frequency hearing loss is consistent with an accelerated aging (presbycusis); low-frequency hearing loss in middle age is unexpected. Because some vowels and consonants have predominantly low-frequency acoustic energy, poor low-frequency hearing may impair communication in HIV+ individuals.

Abstract
Two lines of investigation have highlighted the importance of antibodies to the V1/V2 domain of gp120 in providing protection from HIV-1 infection. First, the recent RV144 HIV-1 vaccine trial documented a correlation between non-neutralizing antibodies to the V2 domain and protection. Second, multiple broadly neutralizing monoclonal antibodies to the V1/V2 domain (e.g. PG9) have been isolated from rare infected individuals, termed elite neutralizers. Interestingly, the binding of both types of antibodies appears to depend on the same cluster of amino acids (positions 167–171) adjacent to the junction of the B and C strands of the four-stranded V1/V2 domain β-sheet structure. However, the broadly neutralizing mAb, PG9, additionally depends on mannose-5 glycans at positions 156 and 160 for binding. Because the gp120 vaccine immunogens used in previous HIV-1 vaccine trials were enriched for complex sialic acid-containing glycans, and lacked the high mannose structures required for the binding of PG9-like mAbs, we wondered if these immunogens could be improved by limiting glycosylation to mannose-5 glycans. Here, we describe the PG9 binding activity of monomeric gp120s from multiple strains of HIV-1 produced with mannose-5 glycans. We also describe the properties of glycopeptide scaffolds from the V1/V2 domain also expressed with mannose-5 glycans. The V1/V2 scaffold from the A244 isolate was able to bind the PG9, CH01, and CH03 mAbs with high affinity provided that the proper glycans were present. We further show that immunization with A244 V1/V2 fragments alone, or in a prime/boost regimen with gp120, enhanced the antibody response to sequences in the V1/V2 domain associated with protection in the RV144 trial.

Abstract
BACKGROUND & OBJECTIVES Newly diagnosed HIV patients may be asymptomatic or present with a wide range of symptoms related to opportunistic infections, acute seroconversion illness or other medical illnesses. This study was designed to evaluate the socio-demographic parameters, spectrum of the presenting clinical conditions and concurrent immunological status of newly diagnosed HIV patients and document the WHO clinical stages at the time of HIV diagnosis. METHODS This cross-sectional, observational study was undertaken over a 12 month period at a tertiary referral hospital in eastern India. Three hundred sixty consecutive newly diagnosed HIV patients were selected for the study from the HIV clinic and medicine wards of this hospital. Demographic and clinical data and relevant laboratory investigations of the patients were recorded and analyzed. RESULTS Mean age of patients was 36.38±10.62 yr, while 63.89 per cent were males. The main mode of transmission of HIV for males and females were unprotected exposure to commercial sex (139, 60.44%) and intercourse with HIV seropositive spouses (89, 68.46%), respectively. Fever (104, 28.89%), weight loss (103, 28.61%) and generalized weakness (80, 22.22%) were the predominant symptoms. Overall mean CD4 count was 176.04±163.49 cells/μl (males 142.19±139.33 cells/μl; females 235.92±185.11 cells/μl). Overall, 224 opportunistic infections were documented in 160 patients, opportunistic diarrhoea (44, 12.22%) and pulmonary tuberculosis (39, 10.83%) being the commonest. There were 83 and 133 patients in WHO clinical stages 3 and 4, respectively; 291 (80.83%) patients were eligible for initiation of first-line antiretrovirals at presentation. INTERPRETATION & CONCLUSIONS Advanced immunodeficiency and burden of opportunistic infections characterize newly diagnosed HIV patients in eastern India. The physicians should keep in mind that these patients may have more than one clinical condition at presentation.

Abstract
BACKGROUND & OBJECTIVES Progressive multifocal leucoencephalopathy (PML) is seen mostly in advanced human immunodeficiency virus (HIV) infection. Little is known about the epidemiology and disease course of these patients from India. This study was aimed to determine the frequency of PML in patients with HIV/AIDS, and the clinical features and survival of these patients. METHODS The charts of HIV/AIDS patients with PML seen over a period of five years (2006-2011) at the Antiretroviral treatment (ART) centre at a tertiary care centre in New Delhi, India, were retrospectively reviewed. RESULTS Of 1465 patients with HIV/AIDS, 18 (1.2%) were diagnosed with PML; four were laboratory confirmed and 14 had consistent clinical and radiological features. PML was the initial presentation of HIV infection in 10 (56%) patients, and 16 (89%) patients had CD4 count less than 200/μl. Insidious onset focal limb weakness (78%) and visual disturbance (28%) were common symptoms. Magnetic resonance imaging (MRI) of the brain revealed characteristic white matter lesions in all the patients. The estimated median survival was 7.6 months (95% CI, 0-20 months). INTERPRETATION & CONCLUSIONS Our results show that the patients present late to access treatment with advanced immunosuppression at presentation. PML is associated with high morbidity and mortality despite institution of highly active antiretroviral therapy (HAART). There is a need to address the lacuna in diagnostic and management services for these patients in India.

Abstract
BACKGROUND & OBJECTIVES HIV/AIDS patients may have renal involvement also, however, Indian data are sparse. The present study was done to find the spectrum of renal diseases in HIV/AIDS patients in north India. METHODS In this prospective pilot study, HIV positive patients aged >18 yr were screened for renal involvement [serum creatinine >1.5 mg% and/or significant proteinuria (>500 mg /day)]. Patients who were positive on screening were followed up prospectively and underwent kidney biopsy if indicated. RESULTS A total of 526 patients were screened, of these, 91 (17.3%) were found to have renal involvement. Group A (Treatment naοve) comprised 392 patients who were not on antiretroviral treatment (ART) and group B (patients on ART) comprised 134 patients. More patients (74/392, 18.9%) in group A had renal involvement as compared to patients in group B (17/134, 12.7%). Of the 91 patients with renal involvement, 26 were followed up and underwent kidney biopsy. Thirteen patients had only proteinuria and another 13 had renal dysfunction with or without proteinuria. Most common histological diagnosis was mesangioproliferative glomerulonephritis (mes PGN) (10/26). Two patients had collapsing FSGS (focal segmental glomerulosclerosis) and three patients had immune complex glomerulonephritis. Seven patients had acute kidney injury, whom six totally recovered from their renal function. All patients with mesPGN tolerated angiotensin converting enzyme (ACE) inhibitors well. There was mixed response of collapsing FSGS to steroids. Both patients with MPGN (membranoproliferative glomerulonephritis) did well on low dose of steroid and ART. INTERPRETATION & CONCLUSIONS Renal involvement was found to be common in HIV positive patients (17.3%). A low occurrence of renal involvement found in patients already on ART suggests some renoprotective effect of ART. Our preliminary results showed that collapsing FSGS was not rare in Indian HIV positive population, but classical HIV associated nephropathy was not seen. Longitudinal studies with robust study design and large sample size need to be done to confirm the findings.

Abstract
BACKGROUND Human papillomavirus (HPV) RNA detection is reportedly more specific for the detection of anogenital precancer than HPV DNA but it is unknown whether this is due to detection of RNA or due to HPV genotype restriction. METHODS A total of 363 human immunodeficiency virus (HIV)-positive men who have sex with men had two anal cytology samples taken and were evaluated using high-resolution anoscopy and biopsies of visible lesions. Anal specimens were tested for E6/E7 RNA for five carcinogenic HPV genotypes (HPV16, 18, 31, 33, and 45) and tested for the DNA of 13 carcinogenic HPV genotypes. RESULTS DNA testing was more likely to be positive than RNA testing (53% vs. 48%; P = 0.02) for the same five HPV genotypes in aggregate. When restricted to five HPV genotypes targeted by the RNA test, the sensitivity to detect anal precancer was the same for DNA and RNA (81%), whereas RNA was more specific than DNA (65% vs. 58%; P = 0.007). In comparison, DNA detection of all 13 carcinogenic HPV genotypes was more sensitive (96% vs. 81%; P = 0.001) but much less specific (65% vs. 33%; P < 0.001) as compared with RNA detection of the five HPV genotypes. CONCLUSION After controlling for HPV genotypes, RNA was only slightly more specific than DNA detection for anal precancer. IMPACT DNA or RNA testing for a subset of the most carcinogenic HPV genotypes may be useful for distinguishing between those HPV-positive men at higher and lower risk of anal precancer and cancer.

Abstract
OBJECTIVES Vapreotide, a synthetic analog of somatostatin, has analgesic activity most likely mediated through the blockade of neurokinin-1 receptor (NK1R), the substance P (SP)-preferring receptor. The ability of vapreotide to interfere with other biological effects of SP has yet to be investigated. METHODS We studied the ability of vapreotide to antagonize NK1R in three different cell types: immortalized U373MG human astrocytoma cells, human monocyte-derived macrophages (MDM) and a human embryonic kidney cell line, HEK293. Both U373MG and MDM express endogenous NK1R while HEK293 cells, which normally do not express NK1R, are stably transformed to express human NK1R (HEK293-NK1R). RESULTS Vapreotide attenuates SP-triggered intracellular calcium increases and nuclear factor-κB activation in a dose-dependent manner. Vapreotide also inhibits SP-induced interleukin-8 and monocyte chemotactic protein-1 production in HEK293-NK1R and U373MG cell lines. Vapreotide inhibits HIV-1 infection of human MDM in vitro, an effect that is reversible by SP pretreatment. CONCLUSIONS Our findings indicate that vapreotide has NK1R antagonist activity and may have a potential application as a therapeutic intervention in HIV-1 infection.

Abstract
Infectious pseudotumors are unusual proliferations of histiocytes in response to certain microbial organisms. Occasionally this process may involve large airways, producing a mass lesion that may cause respiratory obstruction. Infectious pseudotumors can be confused with malignancy in their radiologic appearance and clinical presentation. We present a case of an aggressive endotracheal pseudotumor associated with Rhodococcus equi infection in a patient with advanced HIV disease. Microscopically, the lesion was composed of sheets of epithelioid histiocytes with large, strongly eosinophilic intra-cytoplasmic granules and features of malakoplakia. In this report, we review the literature of these unusual lesions and compare them to cases of conventional malakoplakia involving the large airways. We also explore the pathogenetic mechanisms that may contribute to the distinctive histologic appearance of Rhodococcus-associated pseudotumors.

Abstract
Pneumocystis pneumonia (PcP) remains a significant cause of morbidity and mortality in immunocompromised persons, especially those with human immunodeficiency virus (HIV) infection. Pneumocystis colonization is described increasingly in a wide range of immunocompromised and immunocompetent populations and associations between Pneumocystis colonization and significant pulmonary diseases such as chronic obstructive pulmonary disease (COPD) have emerged. This mini-review summarizes recent advances in our clinical understanding of Pneumocystis and PcP, describes ongoing areas of clinical and translational research, and offers recommendations for future clinical research from researchers participating in the "First centenary of the Pneumocystis discovery".

Abstract
BACKGROUND Few data on the effect of human papillomavirus (HPV) infection on human immunodeficiency virus (HIV) acquisition are available. METHODS HIV-seronegative, sexually active, 18-24-year-old Kenyan men participating in a randomized trial of male circumcision provided exfoliated penile cells from 2 anatomical sites (glans/coronal sulcus and shaft) at baseline. The GP5+/6+ polymerase chain reaction assay ascertained a wide range of HPV DNA types at the baseline visit. The risk of HIV infection was estimated using Kaplan-Meier methods and hazard ratios from proportional hazards models. RESULTS Of 2168 uncircumcised men with baseline HPV data, 1089 (50%) were positive for HPV DNA. The cumulative incidence of HIV infection by 42 months was 5.8% (95% confidence interval [CI], 3.6%-7.9%) among men with HPV-positive glans/coronal sulcus specimens, versus 3.7% [95% CI, 1.8%-5.6%] among men with HPV-negative glans/coronal sulcus specimens (P = .01). Controlling for subsequent circumcision status, baseline herpes simplex virus type 2 serostatus, and sexual and sociodemographic risk factors, the hazard ratio for HIV infection among men with HPV-positive glans/coronal sulcus specimens was 1.8 (95% CI, 1.1-2.9), compared with men with HPV-negative glans/coronal sulcus specimens. CONCLUSION The results suggest an independent increased risk of HIV seroconversion among HPV-positive men. If this finding is confirmed in other studies, HPV prevention could be another tool for HIV prevention.

Abstract
People who use and abuse alcohol and other drugs are an important population to target for HIV prevention because they are more likely to engage in sexual behaviors that increase their likelihood of acquiring or transmitting HIV. A variety of biomedical approaches to HIV prevention have been evaluated or currently are being studied. These approaches include an anti-HIV vaccine; topical protection treatments; and additional biomedical and barrier approaches, such as controlling sexually transmitted diseases, male circumcision, diaphragm use, and substance abuse treatment. The article also reviews topical versus oral antiretrovirals to prevent HIV transmission, antiretroviral treatment as prevention, and the role of alcohol and other drug use in HIV prevention.

Abstract
Alcohol use has negative effects on HIV disease progression through several mechanisms, including transmission, viral replication, host immunity, and treatment efficacy. Research with animal models has explored the effect of alcohol intake on several aspects of simian immunodeficiency virus (SIV) disease progression. Data suggest that the increased SIV levels observed in alcohol-consuming animals may represent an increase in virus production as opposed to a decrease in host defense. Results also suggest that changes in nutritional balance and metabolism, as a possible consequence of a proinflammatory state, together with increased virus production in animals consuming alcohol, accelerate SIV and possibly HIV disease progression. Further studies using the animal model are necessary.

Abstract
Antiretroviral therapy (ART) has substantially altered the fate of HIV-infected people, transforming the infection from an invariably fatal disease to a chronic condition manageable by pharmacotherapy. However, in order for ART to be effective, patients must adhere strictly to an often-demanding treatment regimen. Alcohol consumption may impact survival of HIV-infected patients through a variety of pathways. Some of these are not related to the effectiveness of ART (e.g., alcohol-induced immunosuppression that exacerbates the HIV-related immunosuppression, increased hepatotoxicity, and increased mortality from non-HIV-related causes). However, some pathways mediating alcohol's negative effect on survival are related to ART effectiveness. In particular, alcohol consumption may reduce adherence to ART, leading to decreased ART effectiveness and, ultimately, increased HIV-related mortality. Both clinical data and computer simulations have yielded information about the impact of alcohol consumption on medication adherence in both HIV-infected and noninfected patients. The findings suggest that alcohol-related nonadherence may account for a substantial amount of preventable mortality among HIV-infected patients. These findings may have clinical implications with respect to optimal treatment for HIV-infected patients who also consume alcohol.

Abstract
STUDY DESIGN Resident's case problem. BACKGROUND Kaposi's sarcoma (KS) is the most common form of cancer in patients with human immunodeficiency virus (HIV) infection. Although KS is often initially asymptomatic, this neoplasm may progress to affect multiple organ systems, including structures of the musculoskeletal system, which can produce symptoms similar to those associated with common orthopaedic conditions. This resident's case problem describes the evaluation and differential diagnosis of a 45-year-old male with HIV and KS, referred to physical therapy with an initial diagnosis of radiographic osteoarthritis (OA) and patellofemoral pain syndrome (PFPS) of the left knee. His primary complaint was knee pain during end range knee flexion. DIAGNOSIS The history, systems review, and examination suggested a source of pain of a nonorthopaedic origin. Differential examination ruled out clinical OA, PFPS, ligament/cartilage derangement, and tendonitis. Avascular necrosis of the medial femoral condyle was also considered as a possible source of pain. Recent blood tests indicated a high viral load and low CD4 count, which might have increased susceptibility to opportunistic infections or KS tumor progression. The patient was referred back to his physician for additional follow-up. Magnetic resonance imaging (MRI) of the knees were consistent with a systemic inflammatory process such as KS. A true-cut biopsy was subsequently scheduled, which confirmed KS lesions at the left knee. DISCUSSION Physical therapists who manage orthopaedic conditions should be aware of the disablement that may result from acquired immunodeficiency syndrome-related KS. A thorough joint-specific examination, with a broad differential diagnosis, should be employed for patients having known systemic diseases. LEVEL OF EVIDENCE Differential diagnosis, level 4.

Abstract
Although the introduction of highly active antiretroviral therapy (HAART) has led to a strong reduction of HIV-associated dementia (HAD) incidence, the prevalence of minor HIV-1-associated neurocognitive disorder (HAND) is rising among AIDS patients. HAART medication has shifted neuropathology from a subacute encephalitic condition to a subtle neurodegenerative process involving synaptic and dendritic degeneration, particularly of hippocampal neurons that are spared prior to HAART medication. Considerable neuroinflammation coupled with mononuclear phagocyte activation is present in HAART-medicated brains, particularly in the hippocampus. Accumulating evidence suggests that the resultant elevated secretion of pro-inflammatory cytokines such as interferon-gamma, tumor necrosis factor-alpha, and interleukin-1beta can increase amyloid-beta peptide (Abeta) generation and reduce Abeta clearance. Recent advancements in Alzheimer's disease (AD) research identified Abeta biogenesis and clearance venues that are potentially influenced by HIV viral infection, providing new insights into beta-amyloidosis segregation in HIV patients. Our study suggests enhanced beta-amyloidosis in ART-treated HAD and HIV-associated encephalitis brains and suppression of Abeta clearance by viral infection of human primary macrophages. A growing awareness of potential convergent mechanisms leading to neurodegeneration shared by HIV and Abeta points to a significant chance of comorbidity of AD and HAND in senile HIV patients, which calls for a need of basic studies.
