Comparison of Treatment Patterns in Patients with Migraine Initiating Calcitonin Gene-Related Peptide Monoclonal Antibodies: A Retrospective Real-World US Study.

Background: Calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) are indicated for migraine prevention in the United States. Limited data comparing real-world treatment patterns for CGRP mAbs are available. Objective: To compare the treatment patterns among patients with migraine initiating galcanezumab, fremanezumab, and erenumab. Methods: This retrospective study included adult patients with one or more claims for a self-injectable CGRP mAb (galcanezumab, fremanezumab, or erenumab), with continuous enrollment in medical and pharmacy benefits for 12 months pre-index and 6 and 12 months post-index using MerativeTM MarketScan® Commercial and Medicare databases from May 2017 through March 2021. Propensity-score matching was used to address confounding by observed covariates. Outcomes analyzed included proportion of days covered (PDC), medication-possession ratio (MPR), persistence (≤60-day gap), treatment discontinuation, and switch to a non-index drug. Descriptive X2 and t-test analyses were conducted. Results: At the 12-month follow-up, matched galcanezumab and fremanezumab cohorts each comprised 2674 patients and the galcanezumab and erenumab cohorts 3503 each. The mean (SD) PDC and MPR were both 0.6 (0.3) across all cohorts. Based on PDC ≥0.80 and MPR ≥0.80, a greater proportion of galcanezumab vs fremanezumab (46.2% vs 43.7%, p=0.053; 46.8% vs 44.3%, p=0.053) and galcanezumab vs erenumab (46.2% vs 44%, p=0.156; 46.7% vs 44.5%, p=0.262), respectively, initiators were adherent. Compared to galcanezumab, fremanezumab (248.0 days vs 236.5 days, p=0.001), and erenumab (247.8 days vs 241.7 days, p=0.061) initiators had lower mean persistence. Galcanezumab initiators were less likely to discontinue treatment than fremanezumab (47.8% vs 51.7%, p=0.005) and erenumab (47.7% vs 50.2%, p=0.040) initiators. Across cohorts, most switchers initiated onabotulinum toxin A as subsequent treatment. Similar results were observed for 6-month follow-up cohorts. Conclusion: Patients with migraine who initiated treatment with galcanezumab showed higher persistence and lower treatment discontinuation rates than those initiating either fremanezumab or erenumab.

Perceived racism associated with declines in self-rated oral health among U.S. Black women.

PURPOSE: Racial disparities in oral health are well-documented. Stress has been associated with both perceived racism and oral health, yet little research has directly investigated the association between perceived racism and oral health. METHODS: We used data from the Black Women's Health Study, a longitudinal cohort study that includes a geographically diverse sample of Black women across the United States. Perceived exposure to racism was assessed via two scales, one assessing lifetime exposure and one everyday exposure. Self-rated oral health was subsequently assessed over multiple time points. We used Cox proportional hazard models to calculate adjusted incidence rate ratios estimating the association between higher levels of perceived racism and incident "fair" or "poor" oral health, and explored potential effect measure modification using stratified models. RESULTS: The adjusted incidence rate ratios (n = 27,008) relating perceived racism to incident fair or poor oral health were 1.50 (95% confidence interval 1.35, 1.66) comparing the highest quartile of everyday racism to the lowest and 1.45 (95% confidence interval 1.31, 1.61) for the highest score of lifetime racism compared to the lowest. We did not see evidence of effect modification. CONCLUSIONS: Higher levels of perceived racism documented in 2009 were associated with declines in self-rated oral health from 2011 to 2019.

Hypertensive Disorders of Pregnancy and Risk of Stroke in U.S. Black Women.

BACKGROUND: Black women have a disproportionately higher burden of both preeclamptic pregnancy and stroke compared with White women, but virtually all existing evidence on this possible association has been generated from women of European ancestry. METHODS: In the Black Women's Health Study, a prospective cohort of U.S. Black women who enrolled in 1995, 42,924 participants were parous and free of cardiovascular disease at baseline. Biennial questionnaires included questions on preeclampsia, gestational hypertension, and stroke. We sought the medical records for participants who reported a stroke, and we reviewed them blinded to reproductive history. Cox proportional-hazards models, with control for potential confounders, were used to estimate hazard ratios and 95% confidence intervals (CIs). RESULTS: Over a median of 22 years of follow-up, there were 1555 incident strokes, including 310 among 4938 women with a history of hypertensive disorders of pregnancy (HDOP). The multivariable hazard ratio for stroke for women with any HDOP compared with those who had never experienced HDOP was 1.66 (95% CI, 1.46 to 1.89). Comparable hazard ratios were 1.53 (95% CI, 1.29 to 1.82) for preeclampsia and 1.81 (95% CI, 1.53 to 2.13) for gestational hypertension only. Associations were similar among women under age 55 years and those aged 55 years and older. CONCLUSIONS: In this prospective study of Black women, a history of HDOP was associated with an estimated 66% increased long-term risk of stroke. This association may contribute to the disproportionately higher stroke incidence in Black women given the higher prevalence of HDOP in this population.

Effect of Culturally Tailored, Internet-Delivered Cognitive Behavioral Therapy for Insomnia in Black Women: A Randomized Clinical Trial.

Importance: Black women are at risk for insomnia disorder. Despite interest in addressing sleep health disparities, there is limited research investigating the efficacy of criterion-standard treatment (cognitive behavioral therapy for insomnia [CBT-I]) among this racial minority population. Objective: To compare the efficacy of a standard version of an internet-delivered CBT-I program, a culturally tailored version, and a sleep education control at improving insomnia symptoms. Design, Setting, and Participants: In this single-blind, 3-arm randomized clinical trial, participants in a national, longitudinal cohort (Black Women's Health Study [BWHS]) were recruited between October 2019 and June 2020. BWHS participants with elevated insomnia symptoms were enrolled and randomized in the current study. Interventions: Participants were randomized to receive (1) an automated internet-delivered treatment called Sleep Healthy Using the Internet (SHUTi); (2) a stakeholder-informed, tailored version of SHUTi for Black women (SHUTi-BWHS); or (3) patient education (PE) about sleep. Main Outcomes and Measures: The primary outcome was insomnia severity (Insomnia Severity Index [ISI]). Index score ranged from 0 to 28 points, with those scoring less than 8 points considered to not have clinically significant insomnia symptoms and a score of 15 points or higher suggesting insomnia disorder. An ISI score reduction of more than 7 points was considered a clinically significant improvement in insomnia symptoms. The SHUTi-BWHS program was hypothesized to be more effective at significantly decreasing insomnia severity compared with the SHUTi program and PE. Results: A total of 333 Black women were included in this trial, and their mean (SD) age was 59.5 (8.0) years. Those randomized to receive either SHUTi or SHUTi-BWHS reported significantly greater reductions in ISI score at 6-month follow-up (SHUTi: -10.0 points; 95% CI, -11.2 to -8.7; SHUTi-BWHS: -9.3 points; 95% CI, -10.4 to -8.2) than those randomized to receive PE (-3.6 points; 95% CI, -4.5 to -2.1) (P < .001). Significantly more participants randomized to SHUTi-BWHS completed the intervention compared with those randomized to SHUTi (86 of 110 [78.2%] vs 70 of 108 [64.8%]; P = .008). Participants who completed either intervention showed greater reductions in insomnia severity compared with noncompleters (-10.4 points [95% CI, -11.4 to -9.4] vs -6.2 points [95% CI, -8.6 to -3.7]). Conclusions and Relevance: In this randomized clinical trial, both the SHUTi and SHUTi-BWHS programs decreased insomnia severity and improved sleep outcomes more than PE. The culturally tailored SHUTi-BWHS program was more effective at engaging participants with the program, as a greater proportion completed the full intervention. Program completion was associated with greater improvements in sleep. Trial Registration: ClinicalTrials.gov Identifier: NCT03613519.

Hypertensive diseases of pregnancy and risk of breast cancer in the Black Women's Health Study.

PURPOSE: Compared to white women, Black women have increased risk of developing hypertensive diseases of pregnancy (HDOP) and have a higher incidence of aggressive breast cancer subtypes. Few studies of HDOP and breast cancer risk have included large numbers of Black women. This study examined the relation of HDOP to incidence of breast cancer overall and by estrogen receptor (ER) status in Black women. METHODS: We followed 42,982 parous women in the Black Women's Health Study, a nationwide prospective study of Black women. Multivariable Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) to assess associations of self-reported HDOP, including preeclampsia and gestational hypertension, with breast cancer incidence overall and by ER subtype, adjusted for age and established breast cancer risk factors. RESULTS: Over 20 years of follow-up, we identified 2376 incident breast cancer cases. History of HDOP (11.7%) was not associated with breast cancer risk overall (HR 0.98; 95% CI 0.87, 1.11). HRs for invasive ER+ and ER- breast cancer were 1.11 (95% CI 0.93, 1.34) and 0.81 (95% CI 0.61, 1.07), respectively. CONCLUSIONS: HDOP was not associated with risk of overall breast cancer in Black women. A suggestive inverse association with ER- breast cancer may reflect an anti-tumorigenic hormone profile in HDOP, but those results require confirmation in other studies.

A prospective study of yogurt and other dairy consumption in relation to incidence of type 2 diabetes among black women in the USA.

BACKGROUND: Yogurt consumption and low-fat dairy consumption have been associated with reduced incidence of type 2 diabetes (T2D) in some studies. OBJECTIVE: We assessed the relation of yogurt and other dairy consumption to incidence of T2D in black women, a population group with a disproportionately high incidence of T2D. METHODS: The Black Women's Health Study has followed 59,000 US black women since 1995 through biennial questionnaires which update health information. Each questionnaire inquired about doctor-diagnosed diabetes in the previous 2 y. FFQs completed by participants in 1995 and 2001 provided information on yogurt and other dietary intake. HRs with 95% CIs for yogurt (nonfrozen or frozen) and other dairy consumption in relation to incident T2D (n = 8061 cases) were estimated with Cox proportional hazards regression, controlling for risk factors for T2D. RESULTS: The HR for consumption of ≥1 serving of yogurt/d relative to <1 serving/mo was 0.99 (95% CI: 0.87, 1.13, P trend = 0.65) after control for dietary and nondietary risk factors for T2D. The multivariable HR was 0.97 (95% CI: 0.75, 1.27; P trend = 0.74) for 2 or more servings/d of low-fat dairy other than yogurt relative to <1 serving/mo and 1.06 (95% CI: 0.91, 1.25, P trend = 0.36) for 2 or more servings/d of regular dairy relative to <1 serving/mo. CONCLUSION: Results from this study do not support an inverse association of yogurt consumption or other dairy consumption with T2D risk in black women.

Mental Health Needs of an Emerging Latino Community.

Over the last decade, Baltimore has become a non-traditional sanctuary city, receiving an unprecedented influx of Latino immigrants, mostly from Central America's Northern Triangle, who are often fleeing violence in their home countries. This study explored the nature and frequency of healthcare utilization for mental health problems among uninsured/uninsurable Latinos who received outpatient care between 2012 and 2015 through an academic hospital-affiliated program that covers primary and specialty services to uninsured patients without regard to documentation status. Encounters for mental health disorders were the most common category, accounting for 14.88% of all visits. Mood (78%) and anxiety disorders (16%) were the most prevalent mental health diagnoses. The most frequent reason to seek care was symptom, signs, and ill-defined conditions (37.47%), and within this subgroup, pain was the leading cause of seeking care (88%), which may indicate high rates of somatization of mental health distress. This study presents a unique opportunity to explore the burden and nature of mental health needs among a population for which healthcare information is rarely attainable and highlights the need for culturally competent screening mechanisms and interventions to address the stressors faced by emergent communities.

Immunological and Neurometabolite Changes Associated With Switch From Efavirenz to an Integrase Inhibitor.

BACKGROUND: The biological mechanisms by which efavirenz (EFV) causes central nervous system (CNS) effects are unclear. The objective of this pilot study was to elucidate the mechanisms underlying these CNS effects by correlating well-described neuropsychological (NP) changes with neurometabolites and immunologic markers following switch off EFV. SETTING: Two single-arm parallel switch studies among HIV-infected adults in Boston, USA, from 2015 to 2017. METHODS: Twenty asymptomatic HIV-infected adults on EFV-containing regimens were switched to an integrase strand transfer inhibitor-based regimen for 8 weeks. NP assessments were conducted before and after switch and correlated with neurometabolite changes measured using magnetic resonance spectroscopy and immunological markers. All pre-EFV and post-EFV measures were evaluated using matched-paired analyses. RESULTS: NP testing demonstrated improvement in the domains of mood, cognition, and sleep off EFV. Magnetic resonance spectroscopy revealed decreases in the neurometabolite glutathione level (P = 0.03), a marker of oxidative stress after switch. Inhibitory neuronal activity as reflected by gamma-amino butyric acid levels increased (P = 0.03), whereas excitatory neurotransmitters glutamine + glutamate (Glx) and aspartate decreased (P = 0.04, 0.001). Switching off EFV was also associated with changes in inflammatory markers; plasma markers sCD14 (P = 0.008) decreased, whereas I-FABP and TNFRI levels increased (P = 0.05, 0.03). Cellular markers CD4 and CD8 HLA-DR-/CD38 subsets both increased (P = 0.05, 0.02). CONCLUSIONS: Even asymptomatic participants showed improvements in NP parameters when switched off EFV. These improvements were associated with decreased CNS oxidative stress and excitatory neuronal activity. Changes in immune activation biomarkers suggested overall decreased inflammation. EFV may exert CNS effects through oxidative and inflammatory pathways, providing insight into possible mechanisms of EFV neurotoxicity.

Human Herpes Virus 8 in HIV-1 infected individuals receiving cancer chemotherapy and stem cell transplantation.

BACKGROUND: Human Herpes Virus 8 (HHV8) can cause Kaposi's Sarcoma (KS) in immunosuppressed individuals. However, little is known about the association between chemotherapy or hematopoietic stem cell transplantation (HSCT), circulating HHV8 DNA levels, and clinical KS in HIV-1-infected individuals with various malignancies. Therefore, we examined the associations between various malignancies, systemic cancer chemotherapy, T cell phenotypes, and circulating HHV8 DNA in 29 HIV-1-infected participants with concomitant KS or other cancer diagnoses. METHODS: We quantified HHV8 plasma viral loads and cell-associated HHV8 DNA and determined the relationship between circulating HHV8 DNA and lymphocyte counts, and markers of early and late lymphocyte activation, proliferation and exhaustion. RESULTS: There were no significant differences in plasma HHV8 DNA levels between baseline and post-chemotherapy time points or with the presence or absence of clinical KS. However, in two participants circulating HHV8 DNA increased following treatment for KS or HSCT for lymphoma,. We observed an approximately 2-log10 reduction in plasma HHV8 DNA in an individual with KS and multicentric Castleman disease following rituximab monotherapy. Although individuals with clinical KS had lower mean CD4+ T cell counts and percentages as expected, there were no significant associations with these factors and plasma HHV8 levels. We identified increased proportions of CD8+ and CD4+ T cells expressing CD69 (P = 0.01 & P = 0.04 respectively), and increased CD57 expression on CD4+ T cells (P = 0.003) in participants with detectable HHV8. CONCLUSION: These results suggest there is a complex relationship between circulating HHV8 DNA and tissue-based disease in HIV-1 and HHV8 co-infected individuals with various malignancies.

Human Immunodeficiency Virus Type 1 Persistence Following Systemic Chemotherapy for Malignancy.

Background: Systemic chemotherapies for various malignancies have been shown to significantly, yet transiently, decrease numbers of CD4+ T lymphocytes, a major reservoir for human immunodeficiency virus type 1 (HIV-1) infection. However, little is known about the impact of cytoreductive chemotherapy on HIV-1 reservoir dynamics, persistence, and immune responses. Methods: We investigated the changes in peripheral CD4+ T-cell-associated HIV-1 DNA and RNA levels, lymphocyte activation, viral population structure, and virus-specific immune responses in a longitudinal cohort of 15 HIV-1-infected individuals receiving systemic chemotherapy or subsequent autologous stem cell transplantation for treatment of hematological malignancies and solid tumors. Results: Despite a transient reduction in CD4+ T cells capable of harboring HIV-1, a 1.7- and 3.3-fold increase in mean CD4+ T-cell-associated HIV-1 RNA and DNA, respectively, were observed months following completion of chemotherapy in individuals on antiretroviral therapy. We also observed changes in CD4+ T-cell population diversity and clonal viral sequence expansion during CD4+ T-cell reconstitution following chemotherapy cessation. Finally, HIV-1 DNA was preferentially, and in some cases exclusively, detected in cytomegalovirus (CMV)- and Epstein-Barr virus (EBV)-responsive CD4+ T cells following chemotherapy. Conclusions: Expansion of HIV-infected CMV/EBV-specific CD4 + T cells may contribute to maintenance of the HIV DNA reservoir following chemotherapy.

High-throughput Characterization of HIV-1 Reservoir Reactivation Using a Single-Cell-in-Droplet PCR Assay.

Reactivation of latent viral reservoirs is on the forefront of HIV-1 eradication research. However, it is unknown if latency reversing agents (LRAs) increase the level of viral transcription from cells producing HIV RNA or harboring transcriptionally-inactive (latent) infection. We therefore developed a microfluidic single-cell-in-droplet (scd)PCR assay to directly measure the number of CD4+ T cells that produce unspliced (us)RNA and multiply spliced (ms)RNA following ex vivo latency reversal with either an histone deacetylase inhibitor (romidepsin) or T cell receptor (TCR) stimulation. Detection of HIV-1 transcriptional activity can also be performed on hundreds of thousands of CD4+ T-cells in a single experiment. The scdPCR method was then applied to CD4+ T cells obtained from HIV-1-infected individuals on antiretroviral therapy. Overall, our results suggest that effects of LRAs on HIV-1 reactivation may be heterogeneous-increasing transcription from active cells in some cases and increasing the number of transcriptionally active cells in others. Genomic DNA and human mRNA isolated from HIV-1 reactivated cells could also be detected and quantified from individual cells. As a result, our assay has the potential to provide needed insight into various reservoir eradication strategies.

Elevated Levels of Microbial Translocation Markers and CCL2 Among Older HIV-1-Infected Men.

The aging of the human immunodeficiency virus type 1 (HIV-1)-infected population obligates a focus on the interaction between aging, comorbid conditions, and HIV-1. We recruited a cohort of HIV-1-infected men aged ≤ 35 years or ≥ 50 years who were receiving fully suppressive antiretroviral therapy (ART). We analyzed plasma markers of inflammation; T-cell activation, exhaustion, proliferation; and innate cellular subsets and functional capacity. Levels of lipopolysaccharide and the plasma marker of chemokine (C-C motif) ligand 2 were significantly elevated in older HIV-infected men despite comparable cellular phenotypes. Compared with similarly age-stratified uninfected subjects, older HIV-1-infected adults were also more frequently in the upper quartile of soluble CD14 expression.

Antiretroviral-free HIV-1 remission and viral rebound after allogeneic stem cell transplantation: report of 2 cases.

BACKGROUND: It is unknown whether the reduction in HIV-1 reservoirs seen after allogeneic hematopoietic stem cell transplantation (HSCT) with susceptible donor cells is sufficient to achieve sustained HIV-1 remission. OBJECTIVE: To characterize HIV-1 reservoirs in blood and tissues and perform analytic antiretroviral treatment interruptions to determine the potential for allogeneic HSCT to lead to sustained, antiretroviral-free HIV-1 remission. DESIGN: Case report with characterization of HIV-1 reservoirs and immunity before and after antiretroviral interruption. SETTING: Tertiary care center. PATIENTS: Two men with HIV with undetectable HIV-1 after allogeneic HSCT for hematologic tumors. MEASUREMENTS: Quantification of HIV-1 in various tissues after HSCT and the duration of antiretroviral-free HIV-1 remission after treatment interruption. RESULTS: No HIV-1 was detected from peripheral blood or rectal mucosa before analytic treatment interruption. Plasma HIV-1 RNA and cell-associated HIV-1 DNA remained undetectable until 12 and 32 weeks after antiretroviral cessation. Both patients experienced rebound viremia within 2 weeks of the most recent negative viral load measurement and developed symptoms consistent with the acute retroviral syndrome. One patient developed new efavirenz resistance after reinitiation of antiretroviral therapy. Reinitiation of active therapy led to viral decay and resolution of symptoms in both patients. LIMITATION: The study involved only 2 patients. CONCLUSION: Allogeneic HSCT may lead to loss of detectable HIV-1 from blood and gut tissue and variable periods of antiretroviral-free HIV-1 remission, but viral rebound can occur despite a minimum 3-log10 reduction in reservoir size. Long-lived tissue reservoirs may have contributed to viral persistence. The definition of the nature and half-life of such reservoirs is essential to achieve durable antiretroviral-free HIV-1 remission.
