RESUMEN
INTRODUCTION: Cytokine storm syndrome (CTS) is a serious complication of patients with SARS-CoV-2 infection. Treatment and evolution in octogenarians are not well defined. Our objective is to describe its clinical characteristics, the treatments and its clinical evolution. PATIENTS AND METHOD: Retrospective observational study of consecutive patients admitted in the period between March 23 and April 12, 2020 with confirmed SARS-CoV-2 infection, with pneumonia by radiological study or chest tomography, whith STC criteria and who received treatment. We classified patients as those who received only glucocorticoid (GC) pulses, or GC and tocilizumab pulses. We determined serum levels of ferritin, CRP and D-dimers. The final variable was survival. RESULTS: 21 patients, (80-88 years). The mean ferritin was 1056 microg/L (317-3,553), CRP 115.8mg/dL (22-306) and D-dimers 2.9m/L (0.45-17.5). All patients received GC pulses and in 2 cases simultaneously tocilizumab. The mean follow-up time was 13.7 days (8-21). The overall mortality was 38.1% (8/21 patients). The 2 patients who received tocilizumab died. The deceased had significantly higher levels of ferritin (1,254 vs. 925microg/L; P=.045) and CRP (197.6 vs. 76mg / dL; P=.007). At the end of the follow-up, a decrease in the biochemical parameters was observed with ferritin of 727microg/L, CRP of 27mg/dl and D-dimers of 1.18mg/L. In 13/21 patients (61.9%), the CTS was controlled without the need to add other treatments. CONCLUSIONS: STC mortality from SARS-CoV-2 is high despite treatment. A greater inflammatory response was associated with a higher mortality. Although it seems that the early use of GC pulses could control it, and the use of other treatments such as tocilizumab shouldo be, with the study design and its limitations, this conclusion cannot be stablished.
