    Simarteriviruses (Arteriviridae: Simarterivirinae) are commonly found at high titers in the blood of African monkeys but do not cause overt disease in these hosts. In contrast, simarteriviruses cause severe disease in Asian macaques upon accidental or experimental transmission. Here, we sought to better understand the host-dependent drivers of simarterivirus pathogenesis by infecting olive baboons (n = 4) and rhesus monkeys (n = 4) with the simarterivirus Southwest baboon virus 1 (SWBV-1). Surprisingly, none of the animals in our study showed signs of disease following SWBV-1 inoculation. Three animals (two rhesus monkeys and one olive baboon) became infected and sustained high levels of SWBV-1 viremia for the duration of the study. The course of SWBV-1 infection was highly predictable: plasma viremia peaked between 1 × 107 and 1 × 108 vRNA copies/mL at 3–10 days post-inoculation, which was followed by a relative nadir and then establishment of a stable set-point between 1 × 106 and 1 × 107 vRNA copies/mL for the remainder of the study (56 days). We characterized cellular and antibody responses to SWBV-1 infection in these animals, demonstrating that macaques and baboons mount similar responses to SWBV-1 infection, yet these responses are ineffective at clearing SWBV-1 infection. SWBV-1 sequencing revealed the accumulation of non-synonymous mutations in a region of the genome that corresponds to an immunodominant epitope in the simarterivirus major envelope glycoprotein GP5, which likely contribute to viral persistence by enabling escape from host antibodies

    Seroprevalence of Zika virus in wild African green monkeys and baboons

    ABSTRACT Zika virus (ZIKV) has recently spread through the Americas and has been associated with a range of health effects, including birth defects in children born to women infected during pregnancy. Although the natural reservoir of ZIKV remains poorly defined, the virus was first identified in a captive “sentinel” macaque monkey in Africa in 1947. However, the virus has not been reported in humans or nonhuman primates (NHPs) in Africa outside Gabon in over a decade. Here, we examine ZIKV infection in 239 wild baboons and African green monkeys from South Africa, the Gambia, Tanzania, and Zambia using combinations of unbiased deep sequencing, quantitative reverse transcription-PCR (qRT-PCR), and an antibody capture assay that we optimized using serum collected from captive macaque monkeys exposed to ZIKV, dengue virus, and yellow fever virus. While we did not find evidence of active ZIKV infection in wild NHPs in Africa, we found variable ZIKV seropositivity of up to 16% in some of the NHP populations sampled. We anticipate that these results and the methodology described within will help in continued efforts to determine the prevalence, natural reservoir, and transmission dynamics of ZIKV in Africa and elsewhere. IMPORTANCE Zika virus (ZIKV) is a mosquito-borne virus originally discovered in a captive monkey living in the Zika Forest of Uganda, Africa, in 1947. Recently, an outbreak in South America has shown that ZIKV infection can cause myriad health effects, including birth defects in the children of women infected during pregnancy. Here, we sought to investigate ZIKV infection in wild African primates to better understand its emergence and spread, looking for evidence of active or prior infection. Our results suggest that up to 16% of some populations of nonhuman primate were, at some point, exposed to ZIKV. We anticipate that this study will be useful for future studies that examine the spread of infections from wild animals to humans in general and those studying ZIKV in primates in particular.

    32388 Demographic and socioeconomic factors drive disparate outcomes in mycosis fungoides

    Background: Mycosis fungoides (MF) occurs more frequently in young Black patients, though debate persists as to whether this group is at uniformly increased risk of poorer outcomes. Recent studies have postulated that outcomes among Black patients are heterogeneous, though previous literature suggests that demographics may play a role in MF. Methods: Clinicopathologic, sociodemographic, and follow-up data were analyzed for patients with MF at Henry Ford Health Systems in Detroit, MI, over 19 years. Data were analyzed for factors predicting progression-free survival (PFS) via multivariable stepwise Cox proportional hazards regression models and Kaplan-Meier analysis of intersectional demographic groups based on age at diagnosis (\u3c40 or ≥40), race, and sex. Results: Of the 440 patients, a majority (52.7%) were male, and the most common race/ethnicity was White/Caucasian (50.2%), followed by Black/African American (40%). Medicaid insurance was an independent predictor of shortened PFS (HR 3.13, 95% CI 1.46-6.69) regardless of race, and young Black patients had the shortest PFS, with young Black female patients experiencing shorter PFS than their older Black female (P =.027) and younger Black male (P =.014) counterparts. Conclusions: This study provides the strongest evidence to date that demographic and socioeconomic factors should be a part of the prognostic picture in MF. Their predictive value is likely based on societal and additional health-related variables, such as access to care/medication, health literacy, and bias in a provider or health system. It is our hope that this analysis will spur continued discussion as to the cause and effect of such differences in MF outcomes

    Antecedent Immunosuppressive Therapy for Immune-Mediated Inflammatory Diseases in the Setting of a COVID-19 Outbreak

    BACKGROUND: Finite clinical data and understanding of COVID-19 immunopathology has led to limited, opinion-based recommendations for management of immune-mediated inflammatory disease (IMID) patients on immunosuppressive (IS) therapeutics. OBJECTIVE: Determine if IS therapeutic type impacts COVID-19 risk among IMID patients. METHODS: We conducted a retrospective cohort analysis of Henry Ford Health System (HFHS) patients tested for COVID-19 between February 1 RESULTS: Of 213 IMID patients, 36.2% tested positive for COVID-19, who had no greater odds of being hospitalized or requiring ventilation relative to the general population. No IS therapeutic worsened the course of disease after multivariate correction, though multi-drug regimens and biologics predicted an increased and decreased rate of hospitalization, respectively, with the latter driven by TNFα inhibitors. LIMITATIONS: A single-center study somewhat limits generalization to community-based settings. Only patients tested for COVID-19 were analyzed. CONCLUSION: IS therapies for IMIDs are not associated with a significantly greater risk of SARS-CoV-2 or severe sequelae when controlling for other factors, and TNFα inhibitors may decrease odds of severe infection
