ABSTRACT

Objective: To describe the prevalence of antiphospholipid antibodies in coronavirus disease-19 (COVID-19) and to find potential associations between antiphospholipid antibody positivity and clinical outcomes. Methods: From September to November 2020, clinical and laboratory data were collected from 50 COVID-19 patients hospitalized at Saiful Anwar General Hospital in Malang, Indonesia. Antiphospholipid antibodies were measured by finding IgM anti-β2 glycoprotein, lupus anticoagulant, and IgM/IgG anticardiolipin. Clinical characteristics, thrombotic events, ICU admission, and mortality during hospitalization were recorded. Disease severity was defined by the Guidelines for the Prevention and Control of COVID-19, Indonesia. Results: Among 50 patients, 5 patients (10.0%) were positive for antiphospholipid antibodies: 4 patients (80.0%) had IgM anti-β2 glycoprotein and 1 patient had IgG anti-cardiolipin (20.0%) and IgM anti-cardiolipin (20.0%), none of lupus anticoagulant was detected. Antiphospholipid antibodies were associated with anosmia (OR 8.1; 95% CI 1.1-57.9; P=0.018), nausea and vomiting (OR 12.4; 95% CI 1.2-122.6; P=0.010), diarrhea (OR 9.8; 95% CI 1.3-70.9; P=0.010), cardiovascular disease (OR 1.4; 95% CI 1.0-1.9; P=0.001), chronic kidney disease (OR 12.0; 95% CI 1.6-90.1; P=0.05), acute coronary syndrome (OR 29.3; 95% CI 2.0-423.7; P=0.001), moderate (OR 0.11; 95% CI 0.01-1.10; P=0.031) and severe (OR 18.5; 95% CI 1.8-188.4; P=0.002) disease severity, and in-hospital mortality (OR 8.1; 95% CI 1.1-57.9; P=0.018). However, there is no correlation between the presence of antiphospholipid antibody and ICU admission. Conclusions: In summary, the prevalence of antiphospholipid antibodies in COVID-19 patients is low, mainly against IgM anticardiolipin, and is associated with an acute coronary syndrome, gastrointestinal manifestations, moderate and severe disease severity, and increased risk of mortality.

ABSTRACT

Objective To know the difference between chemerin and adipocyte fatty acid-binding protein (AFABP) levels in obese individuals with positive Toxoplasma gondii (T. gondii) immunoglobulin G (IgG) compared with negative T. gondii IgG. Methods This study is a cross-sectional study by using consecutive sampling methods conducted from January to April 2013. The subjects were 57 obese individuals who were divided into obese group of positive and negative T. gondii IgG. The level of chemerin, AFABP and T. gondii IgG was done by ELISA. The data were analyzed by independent t test. Results The results showed that the level of chemerin of positive T. gondii IgG group was significantly higher than the negative T. gondii IgG group [(70.0 ± 16.5) vs. (64.4 ± 16.1) pg/mL; P = 0.003], but there was not significant AFABP difference between seropositive and negative IgG groups [(83.6 ± 41.9) vs. (74.2 ± 36.7) pg/mL; P = 0.598]. Conclusions It can be concluded that the level of chemerin of seropositive T. gondii IgG was higher than that in the negative T. gondii IgG group.
