Abstract

Objective: In our study, we aimed to show whether there is a relationship between antiphospholipid antibody (aPL) positivity and complications of COVID-19. Material and Methods: Eighty-three patients who were diagnosed with COVID-19 infection and hospitalized in the intensive care unit (ICU) of Bakirkoy Dr. Sadi Konuk Research and Training Hospital were included in our study as the case group and 79 healthy volunteers as the control group. Only patients with a positive polymerase chain reaction (PCR) test were included in the case group. Serum antiphospholipid antibodies (aPL IgM/G), C-Reactive Protein (CRP), ferritin, procalcitonin (PCT), plasma D-Dimer levels, prothrombin time (PT), international normalized ratio (INR), and activated partial thromboplastin time (aPTT) were analyzed by routine laboratory methods. Results: Both groups were found statistically similar in terms of gender (χ2 test, p=0.236). The mean age of the case group and control group was 60.54±16.86 and 51.47±14.64 years, respec-tively. When aPL positivity was evaluated between the case and control groups, a statistically remarkable difference was found between the groups (p=0.046). The case group showed an aPL positivity of 7.5% and the control group 1%. The correlation be-tween D-Dimer, PT, INR, aPTT levels, and aPL IgM/G positivity in the case group was significant. Conclusion: Our results revealed that aPL positivity in patients with COVID-19 infection relate to the severity of the disease, in-dependent from age and gender. To confirm the result of this study further studies with participation of larger patient groups from national and international hospitals are required.

COVID-19 HASTALARINDA ANTİFOSFOLİPİD ANTİKOR (AFA) VARLIĞI

Abstract

Amaç: Çalışmamızda antifosfolipid antikor (AFA) pozitifliği ile COVID-19 komplikasyonları arasında bir ilişki olup olmadığını göstermeyi amaçladık.Gereç ve Yöntem: Bakırköy Dr. Sadi Konuk Eğitim ve Araştırma Hastanesi yoğun bakım servisinde yatan COVID-19 enfeksiyonu tanısı almış 83 hasta olgu grubu olarak, 79 sağlıklı gönüllü de kontrol grubu olarak çalışmamıza dahil edildi. Olgu grubuna sadece polimeraz zincir reaksiyon (PZR) test sonucu pozitif olan hastalar alındı. Serum antifosfolipid antikorları (AFA IgM/G), C-Reaktif Protein (CRP), ferritin, prokalsitonin (PCT) ve plazma D-Dimer seviyeleri, protrombin zamanı (PT) ve uluslararası nor-malleştirilmiş oran (INR), aktive parsiyel tromboplastin zamanı (aPTT), rutin laboratuvar yöntemleriyle analiz edildi.Bulgular: Her iki grup cinsiyet açısından istatistiksel olarak ben-zer bulundu (χ2 testi, p=0,236). Olgu grubu ve kontrol grubunun yaş ortalaması sırasıyla 60,54±16,86 ve 51,47±14,64 yıl idi. Olgu ve kontrol grupları arasında AFA pozitifliği değerlendirildiğin-de, gruplar arasında istatistiksel olarak anlamlı fark bulundu (p=0,046). Olgu grubu %7,5 ve kontrol grubu %1 AFA pozitifliği gösterdi. Olgu grubunun D-Dimer, PT, INR, aPTT seviyeleri ile AFA IgM/G pozitifliği arasındaki korelasyon anlamlı bulundu. Sonuç: Sonuçlarımız, COVID-19 enfeksiyonu olan hastalarda AFA pozitifliğinin yaş ve cinsiyetten bağımsız olarak hastalığın şiddeti ile ilişkili olduğunu ortaya koydu. Bu çalışmanın sonucunu doğrulamak için ulusal ve uluslararası hastanelerden daha geniş hasta gruplarının katılımıyla daha ileri çalışmalara ihtiyaç vardır.
