Evaluation of Platelet Indices in Patients with Splanchnic Vein Thrombosis.

ABSTRACT: Splanchnic vein thrombosis (SVT) is a rare and lethal form of venous thrombosis. The role of platelet indices (PI's) is not well studied in SVT. The present study was aimed to assess if the PI's have a significant association with SVT. This was a prospective case control study from coagulation laboratory of Hematology department. A total 100 cases of SVT and 80 controls were screened for PI's (MPV, PCT & PDW) and platelet count (PC) along with routine thrombophilic risk factors. The SVT cases were divided into 3 subgroups, that comprised of EHPVO/ PVT (n = 69), BCS (n = 27), and MVT (n = 4). The mean PC and PCT were significantly lower in patients than the controls. The PDW was significantly higher in cases than in the controls and MPV was relatively higher in cases however did not show statistical significance. In addition, 16 patients were found to have deranged thrombophilic risk factors. Among these, 8 cases had inherited risk factors (2: FVL; 5: PC; 1: PS) and 8 cases had acquired risk factors (2: APL; and 5: multiple factors and one case had both FVL mutation and APL positivity). The PDW and PCT together with PC were found to significantly differ in SVT cases than in controls, particularly in idiopathic cases. It may be worthwhile to explore the utility of PI's as a potential risk factor in SVT.

Project description:Background & aimsWhether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is a risk factor for splanchnic vein thrombosis (SVT) is unknown. This study aims to assess the impact of SARS-CoV-2 infection on the presentation and prognosis of recent SVT and to identify specific characteristics of SARS-CoV-2-associated SVT.MethodsThis is a retrospective study collecting health-related data of 27 patients presenting with recent SVT in the context of SARS-CoV-2 infection in 12 Vascular Liver Disease Group (VALDIG) centres and in comparison with 494 patients with recent SVT before the SARS-CoV-2 pandemic.ResultsTwenty-one patients with SARS-CoV-2 had portal vein thrombosis with or without thrombosis of another splanchnic vein, two had superior mesenteric vein thrombosis, one had splenic vein thrombosis, and three had hepatic vein thrombosis. Diagnosis of SVT was made 10 days (95% CI 0-24 days) after the diagnosis of SARS-CoV-2 infection. Fever (52 vs. 15%; p <0.001) and respiratory symptoms (44 vs. 0%; p <0.001) were more frequent, and median lymphocyte count was lower (1.1 × 103/mm3vs. 1.6 × 103/mm3; p = 0.043) in patients with infection than in those without SARS-CoV-2 infection. A prothrombotic condition was identified in 44 and 52% of patients with and without SARS-CoV-2 infection, respectively (p = 0.5). All patients with SARS-CoV-2 received anticoagulation therapy. During a median follow-up of 250 days, three SARS-CoV-2-infected patients (11%) required intestinal resection for infarction 1 to 3 months after diagnosis of SVT compared with 13 (2.6%) controls (p = 0.044). Partial or complete recanalisation of the thrombosed splanchnic vein was performed in 33% of patients with SARS-CoV-2.ConclusionsSARS-CoV-2 infection can be associated with recent SVT. Intestinal infarction leading to intestinal resection might be more frequent in patients with SARS-CoV-2.Impact and implicationsSARS-CoV-2 infection can be associated with recent SVT. SVT occurring during SARS-CoV-2 infection is characterised by a higher frequency of respiratory symptoms and a lower lymphocyte count. Intestinal infarction leading to intestinal resection appears to occur more frequently in patients with SARS-CoV-2.
