Lymphopaenia in cardiac arrest patients

Lymphopaenia in cardiac arrest patients Background: A decrease in circulating lymphocytes has been described as a marker of poor prognosis after septic shock; however, scarce data are available after cardiac arrest (CA).

Abstract

Background: A decrease in circulating lymphocytes has been described as a marker of poor prognosis after septic shock; however, scarce data are available after cardiac arrest (CA). The aim of this study was to evaluate the impact of lymphopaenia after successful cardiopulmonary resuscitation. Methods: This is a retrospective analysis of an institutional database including all adult CA patients admitted to the intensive care unit (ICU) between January 2007 and December 2014 who survived for at least 24 h. Demographic, CA‑ related data and ICU mortality were recorded as was lymphocyte count on admission and for the first 48 h. A cerebral performance category score of 3–5 at 3 months was considered as an unfavourable neurological outcome. Results: Data from 377 patients were analysed (median age: 62 [IQRs: 52–75] years). Median time to return of spon‑ taneous circulation (ROSC) was 15 [8–25] min and 232 (62%) had a non‑ shockable initial rhythm. ICU mortality was 58% (n = 217) and 246 (65%) patients had an unfavourable outcome at 3 months. The median lymphocyte count on 3 3 admission was 1208 [700–2350]/mm and 151 (40%) patients had lymphopaenia (lymphocyte count <1000/mm ). Predictors of lymphopaenia on admission were older age, a
