Intern Emerg Med. The researchers sum up: "Hyperactivation of platelets could explain the lower platelet count and, importantly, may contribute to the thrombo-inflammatory state associated with COVID-19 infection. On admission day, severe COVID-19 patients had significantly higher white blood count (WBC), neutrophil, and CRP values than moderate COVID-19 patients (p < 0.05). Though these may seem like significant numbers, it is important to remember that the majority of elevated platelet counts are caused by a reactive process, such . Leukoerythroblastic reactions in blood usually indicate a significant deviation to the body’s normal immune response. Platelet counts, MPV, and platelet morphology in COVID-19 patients are normal. This is an important and timely volume. The history of research in homocysteine metabolism can be divided into three periods. “If leukoerythroblastic reactions were cited in peripheral blood and the patient has a cough and pneumonia, we advise physicians to order COVID-19 testing instead of flow cytometry or bone marrow evaluation for suspicion of leukemia.”. The pooled analysis revealed that platelet count was significantly lower in patients with more severe COVID-19 (WMD -31 × 10 9 /L; 95% CI, from -35 to -29 × 10 9 /L). A meta-analysis was performed, with calculation of weighted mean difference (WMD) of platelet number in COVID-19 patients with or without severe disease and odds ratio (OR) of thrombocytopenia for severe form of COVID-19. This is due to a low number of blood cell fragments called platelets (PLATE-lets) or thrombocytes (THROM-bo-sites). 2021 Sep 14;21(1):945. doi: 10.1186/s12879-021-06645-z. 8600 Rockville Pike [] showed that COVID-19 patients with thrombocytopenia had a statistically significantly larger mean platelet volume (MPV, median 10.3 fL) than COVID-19 patients with retained platelet counts (median 9.9 fL).Outside of congenital platelet disorders, an increased mean platelet volume implies an increase in circulating young platelets and is the body's response to thrombocytopenia [].
