Arterial thrombosis and unusual patterns of thrombotic events in young adults patientswith COVID-19 are yet rarely described in this setting and could be underestimated. Thereis a real need for studies to describe the frequency of unusual thrombotic complications.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in Wuhan,
China in December of 2019, has become a worldwide pandemic with widespread illness and
mortality. Clinical manifestations of Coronavirus disease 2019 (COVID-19) are absent or
mild in a substantial proportion of patients who test positive for COVID-19. Although
respiratory compromise is the cardinal feature of the disease, early studies have
suggested that elevated circulating D-dimer levels are associated with mortality
suggesting a distinct coagulation disorder associated with COVID-19. COVID-19 infection
is commonly complicated with pro-thrombotic state and endothelial dysfunction.
Recent autopsy studies of COVID-19 patients supported this hypothesis by demonstrating
the extensive extracellular fibrin deposition and presence of fibrin thrombi within
distended capillaries and small vessels. Observational studies reported an excess of
venous thromboembolic events (deep vein thrombosis (DVT), pulmonary embolism (PE)) among
patients suffering from Covid-19. Retrospective studies have reported thrombotic rates in
excess of 20% to 30%, but the use of prophylactic anticoagulation and duration of
treatment were not consistent between studies. Unrecognized PE and pulmonary in situ
thrombosis were reported as causes of the high mortality observed among COVID-19
patients. There is currently no clear estimation of the risk of arterial and, in
particular, venous thromboembolic complications which depend on local diagnostic and
pharmacological preventive strategies. In addition to D-dimer, a prolonged prothrombin
time (PT) has been associated with decreased survival and increased need for critical
care.
However, arterial thrombosis and unusual patterns of thrombotic events in young adults
patients with COVID-19 are yet rarely described in this setting and could be
underestimated (9). Thus, there is a real need for studies to describe the frequency of
unusual thrombotic complications. Therefore, the purpose of this study will be to explore
thromboembolic risk and associated predicting factors in the young adults' cohort of
noncritically ill COVID-19 patients which will help to optimize diagnostic, therapeutic,
and preventive strategies of COVID-19 related thrombosis.
Diagnostic Test: Thrombophilia screening
Genetic thrombophilia and acquired thrombophilia screening
Inclusion Criteria:
- non-critically ill young adults' patients with COVID-19 admitted to our hospital
will have confirmed unusual thrombotic events and accept recruitment to this study.
After that, we will focus only on previously healthy patients without pre-existing
prothrombotic factors and presented with COVID-19 related unusual thrombotic events
Exclusion Criteria:
- COVID-19 patients below 18 years and above 40 years
- COVID-19 patients diagnosed as critically ill COVID-19
- COVID-19 patients with pre-existing diabetes mellitus (DM), hypertension, ischemic
heart disease (IHD), valvular heart disease, cardiomyopathy and chronic arrhythmia,
dyslipidemia, metabolic syndrome, chronic kidney disease, liver disease, nephrotic
syndrome, previous autoimmune disease, and malignancy
- COVID-19 patients with chronic lung disease or immune compromise
- COVID-19 pregnant women
- COVID-19 patient with history of thrombosis/ psychiatric disorders/ drug abuse
- COVID-19 patient previously diagnosis with congenital thrombophilia
- COVID-19 patient with drug history could induce thrombosis.
- COVID-19 patient unwilling to be followed up.
- Patients are previously diagnosed with one or more risk factors of thrombosis
