Acute portal vein thrombosis secondary to COVID-19: a case report.

BACKGROUND: COVID-19 pneumonia exhibits several extra-pulmonary complications. CASE PRESENTATION: A 23-year old, asthmatic male with coronavirus pneumonia developed with generalized, acute abdominal pain. Further evaluations revealed a mild ascites and portal vein thrombosis although the patient received proper anticoagulation therapy. Routine lab data regarding the secondary causes of portal vein thrombosis were normal. CONCLUSION: We speculated that the underlying cause of portal vein thrombosis in our case was coronaviruses. Therefore, clinicians should always consider thrombosis and other hypercoagulable diseases in patients with COVID-19.

Diagnostic Value of Blood Oxygen Saturation and Serum C-Reactive Protein Level in Predicting Lung Sequels in Coronavirus Disease 2019-Infected Patients: A 12-week Cohort Study.

BACKGROUND: Evidence of Coronavirus disease 2019 (COVID-19) respiratory sequels is restricted and predisposing factors are not well studied more than two years passing pandemic. This study followed COVID-19 patients 12 weeks after discharge from hospital for respiratory sequels. MATERIALS AND METHODS: This was a prospective study on discharged COVID-19 patients in 2021, in Jahrom, Iran. Exposure was COVID-19 clinical features at hospitalization, including symptoms and physical examination and laboratory findings, and primary endpoint was 12-week lung sequel, being evaluated by a chest CT scan. Demographics and previous medical history were considered covariates. SPO2 and CRP 6-week changes were followed as an early tool for prediction of 12-week lung sequel. RESULTS: Totally, 383 participants (17 had sequels) with mean age of 57.43±18.03 years old (50.13% male) completed 12-week study follow-ups. Ninety-one (23.8%) subjects had an ICU admission history. SPO2% in 6th week was statistically significantly associated with a higher rate of 12-week sequelae (P0.001). Also, patients having CT scan scores between 40% to 50% (P=0.012) and higher than 50% (P=0.040) had higher chance of experiencing lung sequelae than patients with CT scan score of below 40%, as well as having ICU admission history and lower SPO2% at 6th week of discharge. There was a statistically significant increasing trend of SPO2% (P0.001) and a statistically significant decreasing trend of CRP levels (P0.001), overall. SPO2% increase after 6 weeks was lower in participants with lung sequels than fully improved ones (P=0.002) and as well as total 12-week change in SPO2% (P=0.001). CRP changes in none of evaluated periods were different among study groups (P0.05). CONCLUSION: Our results were in favor of closely following SPO2 levels after patient discharge, while CRP assessment seems not helpful based on our results.
