Beginning in late 2023, Oropouche virus was identified as the cause of large outbreaks in Amazon regions with known endemic transmission and in new areas in South America and the Caribbean. The virus is spread to humans by infected biting midges and some mosquito species. Although infection typically causes a self-limited febrile illness, reports of two deaths in patients with Oropouche virus infection and vertical transmission associated with adverse pregnancy outcomes have raised concerns about the threat of this virus to human health. In addition to approximately 8,000 locally acquired cases in the Americas, travel-associated Oropouche virus disease cases have recently been identified in European travelers returning from Cuba and Brazil. As of August 16, 2024, a total of 21 Oropouche virus disease cases were identified among U.S. travelers returning from Cuba. Most patients initially experienced fever, myalgia, and headache, often with other symptoms including arthralgia, diarrhea, nausea or vomiting, and rash. At least three patients had recurrent symptoms after the initial illness, a common characteristic of Oropouche virus disease. Clinicians and public health jurisdictions should be aware of the occurrence of Oropouche virus disease in U.S. travelers and request testing for suspected cases. Travelers should prevent insect bites when traveling, and pregnant persons should consider deferring travel to areas experiencing outbreaks of Oropouche virus disease.

BACKGROUND: Medication access and adherence are important determinants of health outcomes. We investigated factors associated with access and cost-related non-adherence to prescriptions in a population-based cohort of systemic lupus erythematosus (SLE) patients and controls. METHODS: Detailed sociodemographic and prescription data were collected by structured interview in 2014-2015 from participants in the Michigan Lupus Epidemiology & Surveillance (MILES) Cohort. We compared access between cases and frequency-matched controls and examined associated factors in separate multivariable logistic regression models. RESULTS: 654 participants (462 SLE cases, 192 controls) completed the baseline visit; 584 (89%) were female, 285 (44%) black, and mean age was 53 years. SLE cases and controls reported similar frequencies of being unable to access prescribed medications (12.1% vs 9.4%, respectively; p=NS). SLE patients were twice as likely as controls to report cost-related prescription non-adherence in the preceding 12 months to save money (21.7% vs 10.4%; p=0.001), but also more likely to ask their doctor for lower cost alternatives (23.8% vs 15.6%, p=0.02). Disparities were found in association with income, race and health insurance status, but main findings persisted after adjusting for these and other variables in multivariable models. CONCLUSION: SLE patients were more likely than controls from the general population to report cost-related prescription non-adherence, including skipping doses, taking less medicine and delaying filling prescriptions, yet less than 1 in 4 patients asked providers for lower cost medications. Consideration of medication costs in patient decision-making could provide a meaningful avenue for improving access and adherence to medications.

Rheumatic diseases are a leading cause of chronic, noncancer pain. Systemic lupus erythematosus (SLE) is a chronic autoimmune rheumatic disease characterized by periodic flares that can result in irreversible target organ damage, including end-stage renal disease. Both intermittent and chronic musculoskeletal pain, as well as fibromyalgia (considered a centralized pain disorder due to dysregulation of pain processing in the central nervous system), are common in SLE. Opioids are generally not indicated for long-term management of musculoskeletal pain or centralized pain (fibromyalgia) because of lack of efficacy, safety issues ranging from adverse medical effects to overdose, and risk for addiction (1,2). In this study of 462 patients with SLE from the population-based Michigan Lupus Epidemiology and Surveillance (MILES) Cohort and 192 frequency-matched persons without SLE, nearly one third (31%) of SLE patients were using prescription opioids during the study period (2014-2015), compared with 8% of persons without SLE (p<0.001). Among the SLE patients using opioids, 97 (68%) were using them for >1 year, and 31 (22%) were concomitantly on two or more opioid medications. Among SLE patients, those using the emergency department (ED) were approximately twice as likely to use prescription opioids (odds ratio [OR] = 2.1; 95% confidence interval [CI] = 1.3-3.6; p = 0.004). In SLE, the combined contributions of underlying disease and adverse effects of immunosuppressive and glucocorticoid therapies already put patients at higher risk for some known adverse effects attributed to long-term opioid use. Addressing the widespread and long-term use of opioid therapy in SLE will require strategies aimed at preventing opioid initiation, tapering and discontinuation of opioids among patients who are not achieving treatment goals of reduced pain and increased function, and consideration of nonopioid pain management strategies.
