Telemedicine and HIV Care Quality Measures During the COVID-19 Pandemic.

BACKGROUND: During the COVID-19 pandemic, telemedicine was adopted to ensure continuity of HIV care. We examined how introducing televisits affected technical quality of care for people with HIV (PWH) during this time. METHODS: PWH receiving HIV care at Howard Brown Health Centers and Northwestern University in Chicago, Illinois were included. HIV care quality indicators were calculated using data extracted from electronic medical records during 4 timepoints every 6 months from March, March 1, 2020 to September 1, 2021. Generalized linear mixed models estimated differences in indicators across timepoints within each site while controlling for multiple observations of individuals. Generalized linear mixed models were also used to compare differences in outcomes among PWH who attended all versus a combination of in-person and televisits versus no televisits across the study time periods. RESULTS: 6447 PWH were included in the analysis. Compared with prepandemic levels, there were significant declines in care utilization and processes of care measures. Measures of HIV virologic suppression, blood pressure control, and HbA1C <7% (in both people with and without diabetes) were stable with no significant differences noted across the study timepoints. Similar trends were observed across all age, race, and sex subgroups. In multivariable models, televisits were not associated with decreased HIV viral suppression. CONCLUSIONS: During the COVID-19 pandemic and rapid implementation of televisits, indicators of care utilization and processes of care decreased compared with prepandemic levels. Among PWH who remained in care, televisits were not associated with worse virologic, blood pressure, and glycemic control in PWH.

Tecovirimat Use in Ambulatory and Hospitalized Patients With Monkeypox Virus Infection.

ABSTRACT: In this case series of 20 ambulatory and hospitalized adult patients treated for monkeypox virus at a large academic medical center in Chicago, Illinois, tecovirimat use was reserved for those with or at high risk of severe disease, delayed because of logistical and clinical factors, but well tolerated.

Disseminated Streptococcus pneumoniae infection associated with an intrauterine device.

Streptococcus pneumoniae is a common pathogen afflicting a wide variety of disease in both immunocompetent and immunocompromised individuals. Presentation can be variable in initial symptomatology leading to difficulties in diagnosis and management. We present a case of septic shock due to Streptococcus pneumoniae associated with an intrauterine device (IUD) in an immunocompromised patient.

Inflammatory Biomarkers and Mortality Risk Among HIV-Suppressed Men: A Multisite Prospective Cohort Study.

BACKGROUND: Human immunodeficiency virus (HIV)-induced inflammation and immune activation persist after initiation of combination antiretroviral therapy (cART) and HIV suppression and may contribute to mortality risks that exceed those in HIV-uninfected populations, though associations are unclear. METHODS: In the prospective Multicenter AIDS Cohort Study, comprising men who have sex with men from Baltimore, Chicago, Los Angeles, and Pittsburgh, concentrations of 24 biomarkers of inflammation and immune activation were measured in stored serum from HIV-positive men obtained after cART-induced HIV suppression between 1996 and 2009. The outcome was nonaccidental death, with follow-up until 2014. We used Cox proportional hazards models to test whether biomarker concentrations predict time from HIV suppression to death and adjusted for multiple tests. Exploratory factor analysis (EFA) was employed to identify groupings of biomarkers that predict mortality risk. RESULTS: Of 670 men followed up from HIV suppression, 54 died by the end of 2013. After adjustment for age, CD4(+) cell count, hepatitis B or C virus infection, and smoking, concentrations in the highest quartile of 4 biomarkers were significantly associated with mortality risk after controlling the false discovery rate at 5%: interleukin (IL) 6 (hazard ratio, 3.54; 95% confidence interval, 2.06-6.10), soluble IL 2Rα (3.29, 1.85-5.85), soluble CD14 (2.67, 1.55-4.61), and chemokine (CXC motif) ligand 13 (CXCL13; 2.26; 1.29-3.95). EFA yielded 2 biomarker groupings that were independent predictors of mortality risk. CONCLUSIONS: Despite having undetectable HIV RNA levels during cART, men with higher concentrations of several biomarkers (particularly IL 6, soluble IL 2Rα, soluble CD14, and CXCL13) had higher hazards of long-term mortality. Correlations observed among biomarker concentrations may represent underlying inflammatory processes that contribute to mortality risk.

Comparison of HIV Testing Uptake in an Urban Academic Emergency Department Using Different Testing Assays and Support Systems.

Despite 2006 recommendations by the Centers for Disease Control and Prevention for opt-out HIV testing in all healthcare settings, Emergency Department (ED) testing has been limited. We conducted an observational cohort study to assess the impact of two workflow interventions on the proportion of HIV tests ordered in an urban academic ED. First, a 4(th)-generation HIV antigen/antibody combination test replaced the existing assay, and ED staff continued to notify patients of their reactive tests. Six months later, the HIV Rapid Diagnosis Team, composed of an Infectious Diseases (ID) physician and the HIV Advanced Practice Nurse, immediately assisted with disclosure of positive results to the patients and facilitated linkage to outpatient care. The new assay did not change the proportion of HIV tests ordered (0.14-0.11%, χ2, p = 0.2). However, ID support was associated with a statistically significant increase in the proportion of HIV tests ordered (0.14-0.43%, χ2, p < 0.00010) and a nonstatistically significant increase in the proportion of new HIV diagnoses (1.6-6.8%, Fisher exact test = 0.113). Male gender and lack of insurance were associated with a reactive HIV test. Reduction of barriers to linkage to outpatient HIV care through a collaborative relationship between the ED and ID team increased HIV testing and diagnosis. The role of this model as a component of a universal HIV screening program will need to be further assessed.

Improved detection of acute HIV-1 infection in sub-Saharan Africa: development of a risk score algorithm.

OBJECTIVE: Individuals with acute (preseroconversion) HIV infection (AHI) are important in the spread of HIV. The identification of AHI requires the detection of viral proteins or nucleic acids with techniques that are often unaffordable for routine use. To facilitate the efficient use of these tests, we sought to develop a risk score algorithm for identifying likely AHI cases and targeting the tests towards those individuals. DESIGN: A cross-sectional study of 1448 adults attending a sexually transmitted infections (STI) clinic in Malawi. METHODS: Using logistic regression, we identified risk behaviors, symptoms, HIV rapid test results, and STI syndromes that were predictive of AHI. We assigned a model-based score to each predictor and calculated a risk score for each participant. RESULTS: Twenty-one participants (1.45%) had AHI, 588 had established HIV infection, and 839 were HIV-negative. AHI was strongly associated with discordant rapid HIV tests and genital ulcer disease (GUD). The algorithm also included diarrhea, more than one sexual partner in 2 months, body ache, and fever. Corresponding predictor scores were 1 for fever, body ache, and more than one partner; 2 for diarrhea and GUD; and 4 for discordant rapid tests. A risk score of 2 or greater was 95.2% sensitive and 60.5% specific in detecting AHI. CONCLUSION: Using this algorithm, we could identify 95% of AHI cases by performing nucleic acid or protein tests in only 40% of patients. Risk score algorithms could enable rapid, reliable AHI detection in resource-limited settings.

Genital tract reservoirs.

PURPOSE OF REVIEW: The purpose of this article is to review recent findings about HIV in the genital tract. HIV is primarily a sexually transmitted disease, and the efficiency of transmission must reflect the biology of the genital tract. In addition, it has become increasingly clear that the male and female genital tract represent a unique reservoir that requires independent and detailed study. RECENT FINDINGS: This review will address new data on the source of HIV in the genital tract, factors that affect HIV genital viral burden, ways that genital HIV differs from circulating HIV, drug resistance in the genital tract, and new insights and models of genital HIV transmission and immune response. SUMMARY: Understanding how HIV infects, resides, and survives in the genital milieu is critical to understanding the disease itself, and devising ways to halt its spread.

The role of sexually transmitted diseases in HIV transmission.

More than 42 million people worldwide are now infected with HIV, in spite of sustained prevention activities. Although the spread of HIV has been primarily sexual, epidemiological studies have indicated that the efficiency of the spread of HIV is poor, perhaps as infrequently as 1 in every 1,000 episodes of sexual intercourse. However, sexually transmitted diseases (STDs) that cause ulcers or inflammation greatly increase the efficiency of HIV transmission--by increasing both the infectiousness of, and the susceptibility to HIV infection. STDs might be particularly important in the early stages of a localized HIV epidemic, when people with risky sexual behaviour are most likely to become infected. In China, eastern Europe and Russia, there has been a remarkable increase in the incidence of STDs in recent years, and this is reflected in the rapid increase in the spread of HIV in these areas. Targeted STD detection and treatment should have a central role in HIV prevention in these emerging epidemics.

Distribution of the CCR5 gene 32-base pair deletion and CCR5 expression in Chinese minorities.

China has an ethnically diverse population. Genetic differences may contribute to disparities in the efficiency of HIV transmission. To further characterize this risk, we examined the HIV-related genetic diversity in the predominant Han Chinese and in six minority groups. We searched for the delta32-CCR5 mutation, a common cause of relative HIV resistance in the white population. In addition, CCR5 receptor expression was measured. Blood samples were obtained from adults belonging to the Han, Meng, Zang, Weiwuer, Zhuang, Yi, and Dai ethnic groups. Polymerase chain reaction analysis was performed on genomic DNA samples. Surface expression of CCR5 on peripheral blood mononuclear cells was measured by flow cytometry. One-way ANOVA was used to determine mean statistical differences. Samples from 10 members of each minority were examined. A delta32-CCR5 heterozygote phenotype was detected in one Weiwuer subject, but no mutations were found in the other 69 subjects studied. The mean CCR5 expression of cells harvested from the Dai minority was greater than that of cells from all other minorities studied, for both CD3+CCR5+ and CD4+CCR5+ sets (p < .01, one-way ANOVA). The delta32-CCR5 mutation seems to be rare in most Han Chinese and the minority populations studied. CCR5 expression appears to be greater in the Dai minority than in the other minorities investigated. The mechanism for this increased expression requires further study.
