RESUMEN
The frontline immuno-chemotherapy regimen for HIV-associated non-Hodgkin Lymphoma is dose-adjusted EPOCH ± R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab). Chemotherapy-induced peripheral neuropathy (CIPN), caused by vincristine, is a common adverse effect of EPOCH ± R, negatively impacting long-term patient outcomes. The primary objective of this study was to determine the incidence of CIPN, stratified by HIV status, in patients treated with EPOCH ± R. A retrospective cohort study at a tertiary referral comprehensive cancer center evaluated patients treated with EPOCH ± R from 2011 to 2018. The final sample included 27 patients with HIV compared to 279 without HIV (total n = 306). Overall, the incidence of CIPN was 29.4% (n = 90), including 5 with HIV (18.5%) and 85 without HIV (30.5%). Propensity scores were used to match patients by HIV status. Although no relationship was found between HIV status and neuropathy, CIPN affects too many undergoing treatments for lymphoma, supporting future investigations to minimize toxicities.

BACKGROUND: Monoclonal antibody therapy (MAT) received Food and Drug Administration (FDA) Emergency Use Authorization (EUA) for mild to moderate COVID-19 treatment in adults at a high-risk for progression to severe disease in November 2020. This study assessed the impact of MAT on clinical outcomes. METHODS: We conducted a single-center, retrospective study comparing 30-day COVID-19-related emergency department (ED) visits, admissions, and mortality in patients receiving MAT (bamlanivimab, bamlanivimab-etesevimab, or casirivimab-imdevimab) between 16 November 2020 and 19 June 2021, compared to a control group of high-risk adults diagnosed with mild to moderate COVID-19 prior to MAT availability between 16 May 2020 and 15 November 2020. Statistical analysis used logistic regression analysis with backward selection to determine the odds ratios and 95% confidence interval evaluating the relationship between clinical characteristics and outcomes. RESULTS: 1187 patients who received MAT were compared to 1103 patients not treated with MAT. Multivariable regression model adjusted for possible confounders showed patients who received MAT had lower rates of ED visits (3.2% vs 7.4%, OR = 0.46, 95% CI = 0.31-0.70, p < .001) and hospital admissions (4.3% vs 7.8%, OR = 0.42, 95% CI = 0.29-0.62, p < .001) compared to the control group. After adjusting for confounders, MAT was associated with decreased mortality (OR = 0.36, p = .035). In the MAT group, those treated within 2 days of COVID-19 diagnosis had lower mortality than those treated more than 2 days post-diagnosis (unadjusted OR = 0.152, 95% CI = 0.031-0.734, p = .019). CONCLUSIONS: Individuals treated with MAT had lower rates of 30-day COVID-19-related ED visits and hospital admissions compared to those not receiving MAT. Early MAT resulted in lower 30-day mortality compared to receipt >2 days post COVID-19 diagnosis.
