Hemophagocytic lymphohistiocytosis (HLH) is a highly detrimental syndrome that can progress to multiorgan failure, necessitating the resources of an intensive care unit, with a mortality rate as high as 40%. Secondary HLH is usually triggered by infection, most often from a viral infection or malignancy. Management of HLH in adults is challenging as treatment algorithms targeting hyperinflammation are based on pediatric protocols, such as HLH-94 and HLH-2004. To our knowledge, there are only a few reported cases of HLH secondary to ehrlichiosis infection and none in elderly patients with multiple comorbidities. Here, we present a unique case of HLH secondary to ehrlichiosis infection in an 82-year-old female successfully treated with antibiotics and steroids.

356 Background: Healthcare disparities exist in patients living with cancer which could be due to age, sex, race or sociodemographic variables. This study was undertaken to analyze the racial representation in oncology clinical trial study population of selected cancers over a period of 13 years. Methods: ClinicalTrials.gov was utilized for data collection. Clinical trials in 4 major cancers were filtered using the following criteria in advanced search: Disease, Study type: Interventional (Clinical trial), Study results: Studies with results, Status: Completed, Location: United States, Phase: 3 or 4, Last updated: 01/01/2009 to 01/01/2022. Prostate Cancer (PC), Colorectal Cancer (CRC), Breast Cancer (BC), and Lung Cancer (LC) were included in the study. Data were collected in an Excel spreadsheet and descriptive statistics were used for analysis. Comparison of racial representation was made with the National Cancer Institute Surveillance, Epidemiology and End Results Program (SEER) 2019 data for respective cancers. Results: 165 (52.21%) studies out of 316 studies, which met inclusion criteria, were disclosing racial demographic data. Breaking down into respective cancers, PC had 57.69%, LC had 59.04%, CRC had 44.12%, and BC had 46.28% clinical trials with racial demographic data. Table shows detailed racial demographic data of cancers included with comparison to SEER’s incidence data. Whites/Caucasians (Whites) were the most common race in all the cancer trials, followed by Asian/Pacific Islanders (API) in LC, CRC and BC while Blacks/African Americans (AA) being second common in PC. American Indians/Alaskan Natives (AI/AN) were least represented in all the cancer trials. In comparison to SEER’s 2019 incidence data AA and AI/AN were under-represented in all the included cancer trials, while Whites were over-represented. Conclusions: It is prudent to address the issue of racial disparities in clinical trials. To begin with, it is imperative to include racial demographics in the results, as only 52.21% trials had racial demographic data. AA and AI/AN are under-represented in all the included cancer trials while Whites were over-represented, hindering the generalization of the trial results. It is important to make changes at the grass root level, meaning at the conception of the trial and at the research regulatory level.[Table: see text]
