RESUMEN

Introduction: Women living with human immunodeficiency virus (WLHIV) face elevated risks of human papillomavirus (HPV) acquisition and cervical cancer (CC). Coverage of CC screening and treatment remains low in low-and-middle-income settings, reflecting resource challenges and loss to follow-up with current strategies. We estimated the health and economic impact of alternative scalable CC screening strategies in KwaZulu-Natal, South Africa, a region with high burden of CC and HIV. Methods: We parameterized a dynamic compartmental model of HPV and HIV transmission and CC natural history to KwaZulu-Natal. Over 100 years, we simulated the status quo of a multi-visit screening and treatment strategy with cytology and colposcopy triage (South African standard of care) and six single-visit comparator scenarios with varying: 1) screening strategy (HPV DNA testing alone, with genotyping, or with automated visual evaluation triage, a new high-performance technology), 2) screening frequency (once-per-lifetime for all women, or repeated every 5 years for WLHIV and twice for women without HIV), and 3) loss to follow-up for treatment. Using the Ministry of Health perspective, we estimated costs associated with HPV vaccination, screening, and pre-cancer, CC, and HIV treatment. We quantified CC cases, deaths, and disability-adjusted life-years (DALYs) averted for each scenario. We discounted costs (2022 US dollars) and outcomes at 3% annually and calculated incremental cost-effectiveness ratios (ICERs). Results: We projected 69,294 new CC cases and 43,950 CC-related deaths in the status quo scenario. HPV DNA testing achieved the greatest improvement in health outcomes, averting 9.4% of cases and 9.0% of deaths with one-time screening and 37.1% and 35.1%, respectively, with repeat screening. Compared to the cost of the status quo ($12.79 billion), repeat screening using HPV DNA genotyping had the greatest increase in costs. Repeat screening with HPV DNA testing was the most effective strategy below the willingness to pay threshold (ICER: $3,194/DALY averted). One-time screening with HPV DNA testing was also an efficient strategy (ICER: $1,398/DALY averted). Conclusions: Repeat single-visit screening with HPV DNA testing was the optimal strategy simulated. Single-visit strategies with increased frequency for WLHIV may be cost-effective in KwaZulu-Natal and similar settings with high HIV and HPV prevalence.

RESUMEN

BACKGROUND: In 2020, 14% of diagnosed persons living with HIV (PLWH) in Kenya were not taking antiretroviral therapy (ART), and 19% of those on ART had unsuppressed viral loads. Long-acting antiretroviral therapy (LA-ART) may increase viral suppression by promoting ART uptake and adherence. We conducted key informant (KI) interviews with HIV experts in Kenya to identify product and delivery attributes related to the acceptability and feasibility of providing LA-ART to PLWH in Kenya. METHODS: Interviews were conducted via Zoom on potential LA-ART options including intra-muscular (IM) injections, subcutaneous (SC) injections, implants, and LA oral pills. KI were asked to discuss the products they were most and least excited about, as well as barriers and facilitators to LA-ART roll-out. In addition, they were asked about potential delivery locations for LA-ART products such as homes, pharmacies, and clinics. Interviews were recorded and transcribed, and data were analyzed using a combination of inductive and deductive coding. RESULTS: Twelve KI (5 women, 7 men) participated between December 2021 and February 2022. Overall, participants reported that LA-ART would be acceptable and preferable to PLWH because of fatigue with daily oral pills. They viewed IM injections and LA oral pills as the most exciting options to ease pill burden and improve adherence. KI felt that populations who could benefit most were adolescents in boarding schools and stigmatized populations such as sex workers. SC injections and implants were less favored, as they would require new training initiatives for patients or healthcare workers on administration. In addition, SC injections would require refrigeration and needle disposal after use. Some KI thought patients, especially men, might worry that IM injections and implants would impact fertility, given their role in family planning. Pharmacies were perceived by most KI as suboptimal delivery locations; however, given ongoing work in Kenya to include pharmacies in antiretroviral delivery, they recommended asking patients their views. CONCLUSION: There is interest and support for LA-ART in Kenya, especially IM injections and LA oral pills. Identifying patient preferences for modes and delivery locations and addressing misconceptions about specific products as they become available will be important before wide-scale implementation.

RESUMEN

BACKGROUND: This post hoc analysis of a large, phase 3 program evaluated the effects of upadacitinib on fatigue, bowel urgency, and abdominal pain in patients with moderately to severely active ulcerative colitis. METHODS: Induction data were pooled from 2 identical studies, the U-ACHIEVE induction and U-ACCOMPLISH studies. Patients in these studies received upadacitinib 45 mg once daily or placebo as induction treatment. Responders to induction treatment were rerandomized in the U-ACHIEVE maintenance study to upadacitinib 15 mg once daily, upadacitinib 30 mg, or placebo. The percentage of patients reporting no abdominal pain and no bowel urgency daily via an electronic diary and a meaningful within-person change (≥5 points) in the Functional Assessment of Chronic Illness Therapy-Fatigue score were evaluated. RESULTS: The results demonstrated a statistically significantly greater percentage of patients reporting no abdominal pain and absence of bowel urgency observed from week 2 (P < .001), with upadacitinib induction treatment and clinically meaningful improvements in Functional Assessment of Chronic Illness Therapy-Fatigue score observed at week 8 (P < .001), when compared with placebo. The maintenance study showed that significant and meaningful improvements in abdominal pain, bowel urgency, and Functional Assessment of Chronic Illness Therapy-Fatigue score achieved during induction were sustained through 52 weeks of maintenance treatment in upadacitinib- vs placebo-treated patients. CONCLUSIONS: The findings of this study support the additional benefit of upadacitinib in treating moderately to severely active ulcerative colitis by demonstrating a statistically significant impact on clinically meaningful symptoms of fatigue, bowel urgency, and abdominal pain.(U-ACHIEVE induction and maintenance studies; NCT02819635; U-ACCOMPLISH induction study; NCT03653026).


A significantly higher percentage of patients with moderately to severely active ulcerative colitis reported no abdominal pain, no bowel urgency, and a meaningful change in fatigue following 8-week upadacitinib induction treatment and 52-week maintenance treatment compared with placebo.

RESUMEN

BACKGROUND: We evaluated the health-related quality of life (HRQoL) benefits of upadacitinib (UPA) induction and maintenance treatment in a phase 3 study of patients with ulcerative colitis (UC) across a broad range of patient-centered outcomes. METHODS: Patients received UPA 45 mg once daily or placebo as induction treatment for 8 weeks. Patients who achieved clinical response were rerandomized to receive once daily UPA 15 mg, 30 mg, or placebo as maintenance treatment for 52 weeks. The percentages of patients reporting a clinically meaningful within-person change from baseline in the Ulcerative Colitis Symptoms Questionnaire, Inflammatory Bowel Disease Questionnaire, Work Productivity and Impairment Questionnaire, 36-Item Short Form Survey, and European Quality of Life-5 Dimension 5 Levels were evaluated at weeks 2 and 8 of induction and at weeks 0 and 52 of maintenance. RESULTS: Significant improvements from baseline in all HRQoL measures except the Work Productivity and Impairment Questionnaire-absenteeism were achieved with UPA (P < .001) vs placebo as early as week 2 of induction. These improvements were sustained at week 52 with significantly more patients treated with either 15 mg or 30 mg UPA vs placebo achieving meaningful within-person change in the Ulcerative Colitis Symptoms Questionnaire; Inflammatory Bowel Disease Questionnaire; overall work impairment, presenteeism, and activity impairment; both 36-Item Short Form Survey Physical and Mental Component Summaries; and European Quality of Life-5 Dimension 5 Levels (P < .001). CONCLUSIONS: Induction treatment with UPA 45 mg significantly improved HRQoL measures. A significantly higher percentage of patients who responded to induction treatment with UPA maintained clinically meaningful improvements consistently across a wide range of HRQoL outcomes after 52 weeks of maintenance therapy with UPA (15 mg and 30 mg) compared with placebo. (ClinicalTrials.gov, Numbers: NCT02819635, NCT03653026).


Patients with moderate-to-severe ulcerative colitis who received upadacitinib induction treatment demonstrated clinically meaningful improvements across multiple health-related quality of life assessments, as early as induction week 2, that persisted with maintenance treatment to 52 weeks, compared with placebo.

RESUMEN

INTRODUCTION: Our objective was to evaluate physicians' perspectives on the clinical utility of pharmacogenetic (PGx) testing in kidney, liver, heart, and lung transplantation (KLHL-Tx). METHODS: A 36-question web-based survey was developed and administered to medical and surgical directors of US KLHL-Tx centers. RESULTS: There were 82 respondents (10% response rate). The majority were men (78%), non-Hispanic whites (70%), medical directors (72%), and kidney transplant physicians (35%). Although 78% of respondents reported having some PGx education, most reported lack of confidence in their PGx knowledge and ability to apply a PGx test. Participants reported mixed views about the clinical utility of PGx testing-most agreed with the efficacy of PGx testing, but not the benefits relative to the risks or standard of care. While 55% reported that testing was available at their institution, only 38% ordered a PGx test in the past year, most commonly thiopurine-S-methyltransferase. Physician-reported barriers to PGx implementation included uncertainty about the clinical value of PGx testing and patient financial burden. CONCLUSION: Together, our findings suggest prospective PGx research and pilot implementation programs are needed to elucidate the clinical utility and value of PGx in KLHL-Tx. These initiatives should include educational efforts to inform the use of PGx testing.

RESUMEN

Aims: To assess stakeholder perspectives regarding the clinical utility of pharmacogenomic (PGx) testing following kidney, liver, and heart transplantation. Methods: We conducted individual semi-structured interviews and focus groups with kidney, liver, and heart transplantation patients and providers. We analyzed the qualitative data to identify salient themes. Results: The study enrolled 36 patients and 24 providers. Patients lacked an understanding about PGx, but expressed interest in PGx testing. Providers expressed willingness to use PGx testing, but reported barriers to implementation, such as lack of knowledge, lack of evidence demonstrating clinical utility, and patient healthcare burden. Conclusion: Patient and provider educational efforts, including foundational knowledge, clinical evidence, and applications to patient care beyond just immunosuppression, may be useful to facilitate the use of PGx testing in transplant medicine.
