Early Tecovirimat Treatment for Mpox Disease Among People With HIV.

Importance: Despite a lack of effectiveness data in humans, tecovirimat was widely prescribed to people with HIV (PWH) with mpox during the 2022 mpox epidemic, particularly PWH with low CD4+ T-cell counts or severe mpox clinical manifestations. Objective: To evaluate if PWH with mpox who were treated with tecovirimat within 7 days of symptom onset were less likely to have mpox disease progression. Design, Setting, and Participants: This cohort study included PWH diagnosed with mpox at 4 hospitals in Atlanta, Georgia, between June 1 and October 7, 2022. Patients were grouped according to whether they were treated with tecovirimat within 7 days of mpox symptom onset (early tecovirimat cohort) or they did not receive tecovirimat or received the drug 7 or more days after symptom onset (late or no tecovirimat cohort). Multivariable logistic regression models were used to identify factors associated with progression of mpox disease. The 2 cohorts were then matched 1:1 using propensity scores based on the identified factors, and mpox disease progression was compared. Exposures: Treatment with tecovirimat within 7 days of mpox symptom onset. Main Outcome and Measures: Progression of mpox disease, defined as the development of at least 1 severe mpox criterion established by the US Centers for Disease Control and Prevention, after symptom day 7. Results: After propensity score matching, a total of 112 PWH were included in the analysis; 56 received tecovirimat within 7 days of mpox symptom onset (early tecovirimat group) and 56 were either treated later or did not receive tecovirimat (late or no tecovirimat group). In the early tecovirimat group, the median (IQR) age was 35 (30-42) years; 54 individuals (96.4%) were cisgender men, 46 (82.1%) were Black individuals, and 10 (17.9%) were individuals of other races (American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, or White) or unknown race. In the late or no tecovirimat group, the median (IQR) age was 36 (32-43) years; 54 (96.4%) were cisgender men, 49 (87.5%) were Black individuals, and 7 (12.5%) were individuals of other races or unknown race. Mpox disease progression occurred in 3 PWH (5.4%) in the early tecovirimat group and in 15 PWH (26.8%) in the late or no tecovirimat group (paired odds ratio, 13.00 [95% CI, 1.71-99.40]; P = .002). Conclusion and Relevance: Results of this cohort study support starting tecovirimat in all PWH as soon as an mpox diagnosis is suspected. Additional research is warranted to confirm these findings.

Associations Between HIV and Severe Mpox in an Atlanta Cohort.

BACKGROUND: In the Southeastern United States, the 2022 mpox outbreak disproportionately impacted people who are black and people with HIV (PWH). METHODS: We analyzed a cohort of 395 individuals diagnosed with mpox across 3 health care systems in Atlanta, Georgia between 1 June 2022 and 7 October 2022. We present demographic and clinical characteristics and use multivariable logistic regression analyses to evaluate the association between HIV status and severe mpox (per the US Centers for Disease Control and Prevention definition) and, among PWH, the associations between CD4+ T-cell count and HIV load with severe mpox. RESULTS: Of 395 people diagnosed with mpox, 384 (97.2%) were cisgender men, 335 (84.8%) identified as black, and 324 (82.0%) were PWH. Of 257 PWH with a known HIV load, 90 (35.0%) had > 200 copies/mL. Severe mpox occurred in 77 (19.5%) individuals and there was 1 (0.3%) death. Tecovirimat was prescribed to 112 (28.4%) people, including 56 (72.7%) people with severe mpox. In the multivariable analysis of the total population, PWH had 2.52 times higher odds of severe mpox (95% confidence interval [CI], 1.01-6.27) compared with people without HIV. In the multivariable analysis of PWH, individuals with HIV load > 200 copies/mL had 2.10 (95% CI, 1.00-4.39) times higher odds of severe mpox than PWH who were virologically suppressed. Lower CD4+ T-cell count showed a significant univariate association with severe mpox but was not found to be significantly associated with severe mpox in multivariable analysis. CONCLUSIONS: PWH with nonsuppressed HIV loads had more mpox complications, hospitalizations, and protracted disease courses than people without HIV or PWH with suppressed viral loads. PWH with nonsuppressed HIV loads who are diagnosed with mpox warrant particularly aggressive monitoring and treatment.

An Alternative to Cytology in Triaging Cisgender Men and Transgender Women With HIV for High-Resolution Anoscopy.

OBJECTIVES: To evaluate high-risk human papillomavirus testing (hrHPV) as an alternative for anal cytology in screening for high-grade anal neoplasia (AIN2-3) among males with HIV. To identify predictive risk factors for AIN2-3 and develop a clinical tool to triage males with HIV for high-resolution anoscopy (HRA) without cytology. DESIGN: Retrospective cohort study of 199 adult cisgender men and transgender women with HIV referred to an anal neoplasia clinic in the Southeastern United States between January 2018 and March 2021. METHODS: Each subject underwent cytology, hrHPV, and HRA. Clinical and sociodemographic risk factors were collected for each subject. Significant risk factors for AIN2-3 were identified using logistic regression, and a triage tool incorporating these factors was developed. Screening test characteristics were calculated for cytology with and without adjunct hrHPV, hrHPV alone, and the triage tool. RESULTS: In multivariate analysis, significant predictors of AIN2-3 were hrHPV positivity (odds ratio [OR] = 11.98, CI = 5.58-25.69) and low CD4 count (OR = 2.70, CI = 1.20-6.11). There was no significant difference in positive or negative predictive values among the tool, stand-alone hrHPV, and anal cytology with adjunct hrHPV. Sensitivity and specificity were not significantly different for stand-alone or adjunctive hrHPV testing. Compared with cytology, stand-alone hrHPV and the novel triage tool reduced unnecessary HRA referrals by 65% and 30%, respectively. CONCLUSIONS: Stand-alone hrHPV would have missed 11 of 74 AIN2-3 and generated 74 fewer unnecessary HRAs than current cytology-based screening patterns, which led to 115 unnecessary HRAs in our cohort. We propose triaging those with low CD4 count, hrHPV positivity, and/or smoking history for HRA.

"DNA signaturing" database construction for Tetradesmus species identification and phylogenetic relationships of Scenedesmus-like green microalgae (Scenedesmaceae, Chlorophyta).

Species identification of Scenedesmus-like microalgae, comprising Desmodesmus, Tetradesmus, and Scenedesmus, has been challenging due to their high morphological and genetic similarity. After developing a DNA signaturing tool for Desmodesmus identification, we built a DNA signaturing database for Tetradesmus. The DNA signaturing tool contained species-specific nucleotide sequences of Tetradesmus species or strain groups with high similarity in ITS2 sequences. To construct DNA signaturing, we collected data on ITS2 sequences, aligned the sequences, organized the data by ITS2 sequence homology, and determined signature sequences according to hemi-compensatory base changes (hCBC)/CBC data from previous studies. Four Tetradesmus species and 11 strain groups had DNA signatures. The signature sequence of the genus Tetradesmus, TTA GAG GCT TAA GCA AGG ACCC, recognized 86% (157/183) of the collected Tetradesmus strains. Phylogenetic analysis of Scenedesmus-like species revealed that the Tetradesmus species were monophyletic and closely related to each other based on branch lengths. Desmodesmus was suggested to split into two subgenera due to their genetic and morphological distinction. Scenedesmus must be analyzed along with other genera of the Scenedesmaceae family to determine their genetic relationships. Importantly, DNA signaturing was integrated into a database for identifying Scenedesmus-like species through BLAST.

The association between comorbidities and coronavirus disease 2019 hospitalization among people with HIV differs by age.

OBJECTIVES: To determine whether factors associated with coronavirus disease 2019 (COVID-19) hospitalization among people with HIV (PWH) differ by age stratum. DESIGN: Retrospective cohort study. METHODS: All adult PWH with a positive SARS-CoV-2 PCR in a public safety-net health system between 1 March 2020 and 28 February 2021 and a Veterans Affairs Medical Center between 1 1 March 2020 and 15 November 2020 in Atlanta, Georgia were included. We performed multivariable logistic regression to determine demographic and clinical factors associated with COVID-19 hospitalization overall and stratified by age less than 50 and at least 50 years. RESULTS: Three hundred and sixty-five PWH (mean age 49 years, 74% cisgender male, 82% black) were included. Ninety-six percent were on antiretroviral therapy (ART), 87% had CD4 + T-cell count at least 200 cells/µl, and 89% had HIV-1 RNA less than 200 copies/ml. Overall, age [adjusted odds ratio (aOR) 95% confidence interval (CI) 1.07 (1.04-1.10)], later date of SARS-CoV-2 infection [aOR 0.997 (0.995-1.00)], heart disease [aOR 2.27 (1.06-4.85)], and history of hepatitis C virus (HCV) [aOR 2.59 (1.13-5.89)] were associated with COVID-19 hospitalization. Age-adjusted comorbidity burden was associated with 30% increased risk of hospitalization [aOR 1.30 (1.11-1.54)]. Among 168 PWH less than 50 years old, older age [aOR 1.09 (1.01-1.18)] and no ART use [aOR 40.26 (4.12-393.62)] were associated with hospitalization; age-adjusted comorbidity burden was not ( P  = 0.25). Among 197 PWH at least 50, older age [aOR 1.10 (1.04-1.16)], heart disease [aOR 2.45 (1.04-5.77)], history of HCV [aOR 3.52 (1.29-9.60)], and age-adjusted comorbidity burden [aOR 1.36 (1.12-1.66)] were associated with hospitalization. CONCLUSION: Comorbidity burden is more strongly associated with COVID-19 hospitalization among older, rather than younger, PWH. These findings may have important implications for risk-stratifying COVID-19 therapies and booster recommendations in PWH.

Isolation of indole-3-acetic acid-producing Azospirillum brasilense from Vietnamese wet rice: Co-immobilization of isolate and microalgae as a sustainable biorefinery.

Production of indole-3-acetic acid (IAA) is well documented in various studies for the bacteria that inhabit the rhizosphere of plants, but with roots of wet rice, the outstandings have been not yet elucidated. This study began with the isolation of bacteria type strain Azospirillum sp. and developed the investigation to a screening of their ability in IAA production. This screening conducted a selection of only bacteria that was capable of the production of IAA with its content of over 25 µg. mL-1 for sequencing. Of 10 isolates only one resulted from the type strain Azospirillum brasilense (A. brasilense) with a similarity of 100%. Various factors that influence A. brasilense in biosynthesizing IAA such as temperature, pH, nitrogen presence and concentration of tryptophan in the culture medium were examined. The results indicated that the culture conditions were suitable for IAA biosynthesis at pH 6.5, 30 °C, culture media with nitrogen, and 0.1% trytophan. The next survey on the role of the immobilization of this bacteria with microalgae in alginate was highlighted to its support in microalgal growth. With the co-immobilization of bacteria and microalgae, the density of Chlorella vulgaris was significantly increased during 15-day culture, inducing 2.2 times of cell content in culture batch microalgae immobilized A. brasilense higher than that free-bacteria.

Patient Experiences with Telemedicine for HIV Care During the First COVID-19 Wave in Atlanta, Georgia.

We explored experiences with telemedicine among persons with HIV (PWH) during the first wave of the coronavirus disease 2019 (COVID-19) pandemic. A convenience sample of adults (>18 years) receiving care in an urban clinic in Atlanta were invited to participate. Patients completed a structured survey that assessed the usefulness, quality, satisfaction, and concerns with telemedicine services (telephone calls) received during the first wave of the COVID-19 pandemic (March-May 2020). Demographic, plasma HIV-1 RNA, and CD4+ T cell count data were obtained through medical chart abstraction. Bootstrapped t-tests and chi-square tests were used to examine differences in patient experiences by age, sex, and race. Of 406 PWH contacted, 101 completed the survey (median age 55 years, 84% men, 77% Black, 98% virally suppressed, median CD4 count 572 cells/µL). The main HIV care disruptions experienced were delays in follow-up visits (40%), difficulty getting viral load measured (35%), and difficulty accessing antiretroviral therapy (21%). Participant ratings for quality (median score 6.5/7), usefulness (median score 6.0/7), and satisfaction (median score 6.3/7) with telemedicine were high. However, 28% of patients expressed concerns about providers' ability to examine them and about the lack of laboratory tests. More women had concerns about providers' ability to examine them (92% vs. 50%, p = .005) and about the safety of their personal information (69% vs. 23%, p = .002) compared with men. No age or race differences were observed. Although PWH are generally satisfied with telephone-based telemedicine, concerns with its use were notable, particularly among women. Future HIV telemedicine models should address these.

Diagnosis and Management of HIV-Associated Pulmonary Diseases in a Ryan White-Funded Primary Care Setting.

Despite widespread use of antiretroviral therapy (ART), people with HIV (PWH) continue to suffer substantial morbidity and mortality from pulmonary diseases. We sought to evaluate the prevalence of pulmonary symptoms, evaluations, and diagnoses (both infectious and noninfectious) among PWH receiving care at one of the largest HIV clinics in the United States. All PWH seen at the Infectious Disease Program in Atlanta, Georgia, from July 2013 to June 2018 were included. Multivariable logistic regression was used to assess the odds of all-cause mortality. Among 8387 patients, median age was 48 years, 35% had documented smoking, 74% were male, and the 47% with ≥1 pulmonary symptom or diagnosis were older and had higher rates of smoking compared to those without any symptoms or diagnoses (p-values <0.0001). Percent on ART was 97% and 81% for individuals with and without symptoms or diagnoses, respectively (p-value <0.0001). Patients with an infectious diagnosis were more likely to have a diagnostic test ordered than those with a noninfectious diagnosis (p-value <0.0001). After adjustment for demographic and clinical risk factors, odds of death were 2.1 times greater [95% confidence interval (CI) = 1.3-3.5] among those with a pulmonary symptom or diagnosis compared to those without. Despite a high prevalence of pulmonary symptoms and diagnoses in this large cohort of PWH, many did not have a complete diagnostic evaluation, particularly those with noninfectious diagnoses. Greater awareness of evaluation and treatment of noninfectious pulmonary diseases among HIV care providers will be critical to improving long-term outcomes for PWH.

Successful Treatment of Pulmonary Edema Caused by Transurethral Resection of the Prostate Syndrome.

BACKGROUND: Transurethral resection of the prostate (TURP) syndrome is a complication of transurethral resection of the prostate procedure. The incidence of TURP syndrome ranges from 0.78% to 1.4%. This syndrome is caused by excessive absorption of electrolyte-free and hypotonic washing solution. The fluids absorb into the circulation, which leads to heart failure, hyponatremia, and a decrease in serum osmolality. Cerebral edema, coma, pulmonary edema, cardiovascular collapse, and even death are common complications. CASE PRESENTATION: We report a patient who suffered severe TURP syndrome after transurethral resection of the prostate procedure. Clinical manifestations were pulmonary edema and respiratory failure. The concentration of Na+ was 112.6 mmol/l, which was severe hyponatremia. The serum osmolality pressure was 234mOsmol/kg, pH was 7.23, pO2 was 45mmHg and pCO2 was 44mmHg. The patient had successfully recovered after being used CPAP-PSV Pro breathing through a mask with + 5cmH2O of PEEP, 8cmH2O of supporting pressure, 70-100% of FiO2, 20mg furosemide of intravenously, 150 mL of 3% NaCl, and 100mL natribicarbonate 8.4%. CONCLUSION: TURP syndrome is a life-threatening complication of transurethral resection of the prostate procedure, which is caused by excessive absorption of electrolyte-free and hypotonic washing solution. Therefore, the patient should be monitored seriously, diagnosed early, and treated promptly.

Criminal Justice Involvement and Abnormal Cervical Cancer Screening Results Among Women in an Urban Safety Net Hospital.

OBJECTIVE: The aim of the study was to elucidate the risk factors underlying abnormal cytology-based cervical cancer screening (Pap testing) in justice-involved women (JIW) compared with non-JIW in an urban safety net hospital. METHODS: Retrospective chart review of women with a history of correctional involvement who received care at Grady Health System between 2010 and 2018 and had a Pap test was performed (n = 191). An age-matched cohort of women with no correctional involvement and had a Pap test at Grady served as the control (n = 394). Variables of interest were age, HIV, smoking, race, mental health history, and history of incarceration. Outcomes of interests were rate of abnormal Pap tests and follow-up. χ2 and logistic regression models evaluated associations between the variables of interest and outcomes. RESULTS: Rates of abnormal Pap tests were significantly higher in JIW (35.6%) than controls (18.5%, p < .0001). Compared with controls, JIW were significantly more likely to have high-grade cervical cytology (odds ratio [OR] = 3.89, p < .0005) and be lost to gynecologic follow-up (OR = 8.75, p < .0001) and a history of severe mental illness (29.5% vs 4.3%, p < .0001). Those with abnormal Pap tests were likely to be HIV-positive (OR = 20.7, p < .001) and have a history of incarceration (OR = 2.33, p < .001). Predictors of high-grade Pap test were smoking history (OR = 0.16, p = .014), HIV-positive (OR = 3.66, p = .025), and history of incarceration (OR = 3.96, p < .0005). CONCLUSIONS: Justice-involved women represent a high-risk subpopulation with significantly increased rates of high-grade cytology and lost to follow-up. This underscores the need for attention to screening programs and follow-up interventions for JIW.

Improved Synthesis of Ag/SiO2 Colloidal Nanocomposites and Their Antibacterial Activity Against Ralstonia solanacearum 15.

Ag/SiO2 colloidal nanocomposites (NCs) were prepared through the semi-continuous chemical reduction of silver ions on a silica surface; NaBH4 was used as a primary reducing agent, while carboxymethyl cellulose (CMC) served as a secondary reductant and a stabilizer at low temperature. Silver nanoparticles (AgNPs) of an average diameter of 3.89±0.18 nm were uniformly and densely dispersed on the SiO2 surface, forming 218.6-nm-sized Ag/SiO2 NCs. The zeta potential of the Ag/SiO2 NCs (-92.6 mV) was more negative than that of silica (-24 mV), indicating their high long-term stability. Furthermore, their proposed formation mechanism was confirmed via Fourier transform infrared spectroscopy. Then, the bactericidal effect of the Ag/SiO2 was evaluated based on their minimal inhibitory concentration (MIC) against Ralstonia solanacearum 15 (R. solanacearum 15); it was 62.5 ppm, much lower than that of conventional AgNPs (500 ppm). Therefore, these highly stable Ag/SiO2 colloidal NCs with more effective antibacterial activity than conventional AgNPs are a promising nanopesticide in agriculture.

Predictors of disparities in retention in care among African Americans living with HIV.

Limited health literacy may contribute to racial disparities in retention in HIV care. The purpose of this study was to evaluate the effects of health literacy and patient and social-level factors on retention in care among African Americans living with HIV. This study included 699 participants recruited from outpatient HIV clinics and retention in care was defined as visit adherence. Multivariable logistic regression models were used to assess predictors of visit adherence among persons with 100% visit adherence compared to less than 100% visit adherence. Controlling for demographic factors, the odds of 100% visit adherence was greater among non-African Americans compared to African Americans. In models that included health literacy, race was no longer significant and health literacy was a significant predictor of 100% visit adherence. Among participants with less than 100% visit adherence, health literacy was not a significant predictor of visit adherence; however, age, marital status, and patient attitudes towards the health care provider were significant predictors. Findings suggest that health literacy may mediate the relationship between race and visit adherence. Future studies should further examine these relationships and develop interventions that target modifiable factors, with a goal of improving health equity and minimizing disparities.

Disparities in Retention in Care Among Adults Living with HIV/AIDS: A Systematic Review.

As national HIV prevention goals aim to increase the proportion of persons living with HIV, determining existing disparities in retention in care will allow for targeted intervention. The purpose of this systematic review was to identify existing disparities in retention in care. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) 2015 guided this systematic review. Electronic databases, including PubMed/MEDLINE, CINAHL, Sociological Collection, PsychInfo, and Cab Direct/Global Health, were systematically searched and twenty studies were included. This review identified disparities in retention in care that have been documented by race, gender, age, HIV exposure, incarceration history, place of birth, and U.S. geographic location. Research is necessary to further identify existing disparities in retention in care and to better understand determinants of health disparities. Additionally, interventions must be tailored to meet the needs of health disparate populations and should be assessed to determine their effectiveness in reducing health disparities.

Pilot Study of Markers for High-grade Anal Dysplasia in a Southern Cohort From the Women's Interagency Human Immunodeficiency Virus Study.

BACKGROUND: Anal cancer rates have increased, particularly in human immunodeficiency virus (HIV)-infected (HIV+) women. We assessed factors associated with anal precancer in HIV+ and at-risk HIV-negative women from the Atlanta Women's Interagency HIV Study cohort. METHODS: All participants underwent high-resolution anoscopy and anal cytology and had anal and cervical samples collected. Specimens were tested for 37 human papillomavirus (HPV) types and for FAM19A4 and microRNA124-2 promoter methylation. Binary logistic regression and multivariate analysis were conducted with histologic anal high-grade squamous intraepithelial lesion (A-HSIL) as the dependent variable. RESULTS: Seventy-five women were enrolled: 52 (69%) were HIV+ with three-fourths having undetectable viral load; 64 (86%) were black; mean age was 49 ± 8 years. Forty-nine (65%) anal cytology samples were abnormal, and 38 (51%) of anal samples were positive for at least 1 of 13 high-risk HPV (hrHPV) types. Thirteen (18%) anal biopsies identified A-HSIL. Hypermethylation of FAM19A4 and/or microRNA124-2 was found in 69 (95%) anal samples and 19 (26%) cervical samples. In multivariate analyses, the odds of having A-HSIL were >6 times higher in women with anal hrHPV (adjusted odds ratio [aOR], 6.08 [95% confidence interval {CI}, 1.27-29.18], P = .02) and with positive cervical methylation (aOR, 6.49 [95% CI, 1.66-25.35], P = .007), but not significantly higher in women with positive anal methylation. CONCLUSIONS: Anal hrHPV and promoter hypermethylation in the cervix show promise as biomarkers for anal cancer screening in HIV+ and at-risk HIV-negative women. Greater understanding of gene silencing by promoter hypermethylation in anal carcinogenesis is needed.

Knowledge of Anal Cancer, Anal Cancer Screening, and HPV in HIV-Positive and High-Risk HIV-Negative Women.

The incidence of anal cancer in HIV-positive women is a growing public health concern where they have a 7.8-fold increased risk for anal cancer than women in the general population. We examined knowledge of anal cancer, anal cancer screening, and HPV in HIV-positive women and high-risk HIV-negative women. Women were recruited from the Women's Interagency HIV Study and completed an adapted Knowledge of Anal Cancer and HPV Scale. Correlations among anal cancer knowledge and sociodemographic and risk factors were assessed using Pearson's or Spearman's rho r test. Student's t test or chi-square tests identified significant differences between groups by HIV status or risk factors. Among 155 women, 72% (n = 113) correctly identified the purpose of an anal Pap test. However, only 42% (n = 65) identified HIV as a risk factor for anal cancer. HIV-positive women were more knowledgeable about anal cancer than high risk HIV-negative women (t = 2.104, p = .037). Women with a history of an abnormal cervical Pap test (t = 2.137, p = .034), younger age (t = 3.716, p = .000), reported history of anal sex (t = 3.284, p = .001), some college education or higher (t = -2.005, p = .047), and non-smokers (t = 2.425, p = .016) were significantly more knowledgeable about HPV. Although most women were knowledgeable about anal cancer, many women could not identify important risk factors for anal cancer, such as HIV infection. Patient educational interventions tailored to HIV-positive women are warranted to improve knowledge and awareness of risk for anal cancer.

A Path Analysis of Patient and Social-Level Factors on Health Literacy and Retention in Care Among African Americans Living with HIV.

Low health literacy and poor retention in care may contribute to HIV health disparities among African Americans, but causal pathways have not been examined. We utilized an adapted health literacy model to examine the role of health literacy on racial disparities in retention in care. Retention in care for 699 participants was assessed 24-months post survey and operationalized as 100% visit adherence versus less than 100% visit adherence. Most participants were African American (60%) and virally suppressed (93%). Results from a path analysis revealed that non-African American race was related to greater health literacy (p = .023) and to 100% visit adherence (p = .024). Greater health literacy was associated with 100% visit adherence (p = .008), which was in turn related to viral suppression (p < .001). Findings indicate that health literacy partially mediates the relationship between race and retention in care and are among the first to suggest these causal pathways.

Improved Perinatal and Postpartum Human Immunodeficiency Virus Outcomes After Use of a Perinatal Care Coordination Team.

In a high-volume clinic in the Southeastern United States, pregnant women living with human immunodeficiency virus (HIV) had improved HIV outcomes up to 6 months after delivery following the introduction of a multidisciplinary perinatal care coordination team.

Not a Disease of the Past: A Case Series of Progressive Multifocal Leukoencephalopathy in the Established Antiretroviral Era.

Progressive multifocal leukoencephalopathy (PML) and PML immune reconstitution inflammatory syndrome (PML-IRIS) can be devastating neurological processes associated with HIV, but limited knowledge of their characteristics in the established antiretroviral therapy (ART) era is available. We conducted a case series to evaluate the clinical course of PML and PML-IRIS at our urban safety-net hospital in Atlanta, GA. All HIV-positive individuals with a positive John Cunningham virus DNA polymerase chain reaction in the spinal fluid between May 1, 2013 to June 1, 2017 were identified from the electronic health records (EHRs) using the HIV Disease Registry. Demographics, symptom presentation, laboratory data, imaging results, treatment, and outcomes were abstracted from the EHR. PML and PML-IRIS were defined using the American Association of Neurology criteria. Of the 32 individuals identified, 6 (19%) were felt to have asymptomatic positive results. Of the remainder, 15 (58%) HIV-positive patients had PML and 11 (42%) PML-IRIS (2 with an unmasking presentation and 9 with a paradoxical presentation). The most common presenting symptoms were motor weakness (18, 69%), cognitive deficits (15, 58%), and dysarthria (11, 42%). Corticosteroids were used in 12 patients and maraviroc in 3 patients. Outcomes were dismal with 7 (47%) patients with PML and 9 (82%) with PML-IRIS dying or being referred to hospice, with median survival times of 266 days in the PML group and 109 days in the PML-IRIS group. Despite widespread access to ART, patients with PML continue to have poor outcomes, particularly among those who develop PML-IRIS. More research is needed to understand the risks for and prevention of PML-IRIS.

Comparison of bead array and glass nanoreactor multi-analyte platforms for the evaluation of CNS and peripheral inflammatory markers during HIV infection.

While human immunodeficiency virus (HIV) infection has become a treatable disease with the development of combination antiretroviral therapy (cART), chronic inflammation that affects the central nervous system and other organs is still common. Reliable methods are needed to study HIV-associated inflammatory biomarkers. In this study involving both plasma and cerebrospinal fluid (CSF), we compared multiplex bead array (MBA) to a relatively new technology based on microfluidics and glass nanoreactor (GNR) technology for the measurement of three commonly studied markers from HIV-infected individuals. We found that results correlated between the two platforms for MCP-1 in both fluids as well as for plasma TNFα (all p < .005). However, results between the two platforms did not correlate for CSF TNFα or fractalkine from plasma or CSF. A statistically significant decrease in CSF TNFα over time (p < .0001) was only detectable with the MBA platform, and TNFα on the MBA was the only CSF biomarker to correlate with CSF HIV RNA (rho = 0.71, p < .0001). Meanwhile, the GNR platform was superior in terms of intra-assay fractalkine (FKN) variability and the detection of a significant FKN decrease over time. Additionally, the only significant correlation between blood biomarkers and plasma HIV RNA was with FKN on the GNR platform (rho = 0.38, p = .015). Given the variability in results between platforms, more research is needed on methods to quantitate HIV-associated inflammation.

Implementation of a Rapid Entry Program Decreases Time to Viral Suppression Among Vulnerable Persons Living With HIV in the Southern United States.

BACKGROUND: Rapid entry programs (REPs) improve time to antiretroviral therapy (ART) initiation (TAI) and time to viral suppression (TVS). We assessed the feasibility and effectiveness of a REP in a large HIV clinic in Atlanta, Georgia, serving a predominately un- or underinsured population. METHODS: The Rapid Entry and ART in Clinic for HIV (REACH) program was implemented on May 16, 2016. We performed a retrospective cohort study with the main independent variable being period of enrollment: January 1, 2016, through May 15, 2016 (pre-REACH); May 16, 2016, through July 31, 2016 (post-REACH). Included individuals were HIV-infected and new to the clinic with detectable HIV-1 RNA. Six-month follow-up data were collected for each participant. Survival analyses were conducted for TVS. Logistic and linear regression analyses were used to evaluate secondary outcomes: attendance at first clinic visit, viral suppression, TAI, and time to first attended provider visit. RESULTS: There were 117 pre-REACH and 90 post-REACH individuals. Median age (interquartile range [IQR]) was 35 (25-45) years, 80% were male, 91% black, 60% men who have sex with men, 57% uninsured, and 44% active substance users. TVS decreased from 77 (62-96) to 57 (41-70) days (P < .0022). Time to first attended provider visit decreased from 17 to 5 days, and TAI from 21 to 7 days (P < .0001), each remaining significant in adjusted models. CONCLUSIONS: This is the largest rapid entry cohort described in the United States and suggests that rapid entry is feasible and could have a positive impact on HIV transmission at the population level.
