Mesenteric Thrombosis

A 52-year-old patient with SARS-CoV-2 was diagnosed with interstitial pneumonia and treated with darunavir/ritonavir, hydroxychloroquine, azithromycin and low molecular weight heparin (LMWH). After LMWH cessation, he developed superior mesenteric arterial thrombosis. An abdominal CT scan showed arterial thrombosis of vessels efferent of the superior mesenteric artery with bowel distension. COVID-19 may predispose to venous and arterial thromboembolism. Anticoagulation prophylaxis should be considered in hospitalized patients with COVID-19, and potential thromboembolism investigated in each symptomatic patient affected by SARS-CoV-2.

Abstract The low-molecular weight heparin nadroparin calcium is used clinically for the prevention and treatment of venous and arterial thrombosis. The antifactor Xa and antifactor IIa assays were validated by investigating the parameters of range, linearity (r2 0.9905 and r2 0.9914, respectively) precision, accuracy, and robustness. The 2 methods incorporated a chromogenic endpoint and detection at 405 nm, yielding good results with detection limits of 0.004 and 0.01 IU/mL and quantitation limits of 0.01 and 0.03 IU/mL, respectively, for the antifactor Xa and antifactor IIa assays. Nadroparin calcium pharmaceutical products were evaluated by the antifactor Xa assay and the antifactor IIa assay, giving potencies between 93.86 and 109.88%, with an antifactor Xa/antifactor IIa ratio between 3.2 and 3.7. The results demonstrated the validity of the assays that are useful methodologies for the routine quality control of nadroparin in pharmaceutical formulations.
