Adherence to antiretroviral therapy and its association with quality of life among people with HIV in the United States.

Adherence to antiretroviral therapy (ART) is critical for people with HIV (PWH) to achieve and maintain virologic suppression and minimize drug resistance. This study aimed to use real-world data to characterize ART adherence and its effect on quality of life (QoL) in PWH. Data were drawn from the Adelphi HIV Disease Specific Programme™, a cross-sectional survey of physicians and PWH in the United States, conducted June-October 2021. Demographic and clinical characteristics, ART adherence and treatment satisfaction for PWH were reported by physicians. PWH completed standardized QoL questionnaires. Adherence level was categorized into completely, mostly and less adherent. Regression analysis was used to investigate factors associated with adherence and the association between adherence and QoL measures. Of 578 PWH, 189 (32.7%) were not completely adherent. Having AIDS-defining illnesses, anxiety/depression or being symptomatic was significantly associated with lower adherence. Reasons for poor adherence included forgetting, difficulties integrating into routine and side effects. QoL scores were significantly higher in the completely adherent group. These findings highlight the strong association between suboptimal adherence and QoL among PWH and key factors and PWH reasons that may lead to suboptimal adherence. Interventions aimed at improving the QoL of PWH by understanding these factors are warranted.

Factors driving decisions in the use of HIV pre-exposure prophylaxis: a real-world study in the United States.

Background: Uptake of pre-exposure prophylaxis (PrEP) in the United States (US) remains below target, despite reported high efficacy in prevention of HIV infection and being considered as a strategy for ending new HIV transmissions. Here, we sought to investigate drivers for PrEP use and barriers to increased uptake using real-world data. Methods: Data were drawn from the Adelphi PrEP Disease Specific Programme™, a cross-sectional survey of PrEP users and PrEP non-users at risk for HIV and their physicians in the US between August 2021 and March 2022. Physicians reported demographic data, clinical characteristics, and motivations for prescribing PrEP. PrEP users and non-users reported reasons for or against PrEP use, respectively. Bivariate analyses were performed to compare characteris tics of users and non-users. Results: In total, 61 physicians reported data on 480 PrEP users and 121 non-users. Mean ± standard deviation of age of users and non-users was 35.3 ± 10.8 and 32.5 ± 10.8 years, respectively. Majority were male and men who have sex with men. Overall, 90.0% of users were taking PrEP daily and reported fear of contracting HIV (79.0%) and having at-risk behaviors as the main drivers of PrEP usage. About half of non-users (49.0%) were reported by physicians as choosing not to start PrEP due to not wanting long-term medication. PrEP stigma was a concern for both users (50.0%) and non-users (65.0%). More than half felt that remembering to take PrEP (57.0%) and the required level of monitoring (63.0%) were burdensome. Conclusions: Almost half of people at risk for HIV were not taking PrEP due to not wanting long-term daily medication and about half of current PrEP users were not completely adherent. The most common reason for suboptimal adherence was forgetting to take medication. This study highlighted drivers for PrEP uptake from physician, PrEP user, and non-user perspectives as well as the attributes needed in PrEP products to aid increased PrEP uptake.

Real-world outcomes in patients with chronic spontaneous urticaria receiving omalizumab: insights from a clinical practice survey.

OBJECTIVE: Chronic spontaneous urticaria (CSU) is a debilitating inflammatory skin condition, often impacting quality of life. International guidelines recommend omalizumab, an anti-immunoglobulin E antibody, for second-line treatment. Our objective was to understand patient characteristics associated with prescription of omalizumab, and assess real-world outcomes in patients with CSU treated with omalizumab. METHODS: We analyzed data from the Adelphi Real World CSU Disease Specific Programme, a cross-sectional survey with retrospective data collection (December 2020-October 2021) from physicians and patients with CSU in the United States. RESULTS: Data from allergists (n = 45), dermatologists (n = 51), and primary care physicians (PCPs; n = 20) were included. At the time of data collection, one-third of patients were receiving omalizumab (n = 220) and 67% were eligible for but not receiving omalizumab (n = 455). Using logistic regression, the odds of receiving omalizumab were higher in patients whose entire bodies were affected by hives [odds ratio (OR) = 2.551; 95% confidence interval (CI) 1.502-4.333; p < 0.001] or with deteriorating/unstable prognoses at treatment initiation [OR = 2.219; 95% CI 1.031-4.777; p = 0.042], and lower in patients managed by PCPs [OR = 0.276; 95% CI 0.130-0.584; p < 0.001]. Estimates from an inverse probability weighted regression adjustment model indicated that patients receiving omalizumab had higher treatment satisfaction, improvements in itching, hives, angioedema, insomnia, and anxiety, and lower impact on work productivity, compared with patients not receiving omalizumab. CONCLUSION: Around two-thirds of patients with CSU considered eligible for omalizumab were not receiving the guideline-recommended therapy. Patients receiving omalizumab had better real-world outcomes compared with patients not receiving omalizumab. Ensuring patients receive the most appropriate treatment could benefit patients with CSU.

People with a skin rash known as chronic spontaneous urticaria (also called long-lasting hives) have itchy spots that last longer than 6 weeks. People with long-lasting hives may be treated with a medicine called omalizumab to help their itching. We asked doctors why they gave some people omalizumab. We found that only one out of every three people with long-lasting hives were given omalizumab. Doctors gave some people omalizumab because they had long-lasting hives on their whole body or their hives were getting worse. Other people received omalizumab because they were seeing a specialist doctor (allergist) instead of a primary care physician (also called a general practitioner). When compared with people who received other medicines, people being treated with omalizumab had reduced itching, less anxiety, and better well-being. These findings could help doctors choose the right medicine for people with long-lasting hives.
