Yoğun Bakımda Yatan COVID-19’lu Hastaların Tedavisinde Erken ve Geç Dönem Konvalesan Plazma Uygulamalarının Retrospektif Olarak Karşılaştırılması
Amaç: Yoğun bakımda konvalesan plazma tedavisi alan Corona- virüs hastalığı 2019 (COVID-19)’lu hastaları tedavi uygulanma za- manlarından yola çıkarak, kan grupları, laboratuvar değerleri ve sonlanım açısından karşılaştırmayı amaçladık. Yöntem: Çalışmada yoğun bakımda 200 mL konvalesan plazma te- davisi almış hastalar retrospektif olarak değerlendirildi. Semptom başlangıcı göz önüne alınarak, erken tedavi grubu (≤ 7 gün) ve geç tedavi grubu (>7 gün) olarak iki gruba ayrıldı. Hastaların demogra- fik özellikleri, kan grupları, komorbiditeleri, tedavileri, laboratuvar değerleri [tedavi öncesi (TÖ), tedavi sonrası 1. Gün (TS1), tedavi sonrası 3. Gün (TS3)] ve sonlanımları (mortalite) karşılaştırıldı. Bulgular: Belirlenen kriterleri karşılayan 152 hasta oldu. Erken (n=82) ve geç (n=70) tedavi grupları arasında demografik özellikler, komorbidite, tedaviler, mortalite, yoğun bakım yatış süreleri açı- sından fark tespit edilmedi. Laboratuvarda TÖ ve TS1’de, erken te- davi grubunda ferritin değeri geç tedavi grubuna göre daha yüksek bulundu (p=0,023, p=0,015). Geç tedavi grubunda, TS3’de C reaktif protein değeri, erken tedavi grubuna göre düşüktü (p=0,011). Te- davinin 1. günü ile 3. günü arasındaki değişim incelendiğinde fer- ritin ve fibrinojen değerlerindeki değişiminin geç tedavi grubunda erken tedavi grubuna göre daha fazla olduğu görüldü (p=0,014, p=0,049). Gruplar arasında, diğer laboratuvar değerlerinde farklı- lık saptanmadı. Erken ve geç dönem tedavi alanlar arasında sonla- nım açısından fark bulunmadı. Sonuç: Çalışmamızda konvalesan plazma verilme zamanının sonla- nım üzerine etkisinin olmadığını gördük. Laboratuvar sonuçlarında bulunan farklılığın kontrollü çalışmalar ile tekrar değerlendirilmesi gerektiği görüşündeyiz.
Comparison of Early and Late Administration of Convalescent Plasma for the Treatment of COVID-19 Patients Hospitalized in Intensive Care Unit Retrospectively
Objective: We aimed to compare laboratory and outcome of the patients who were hospitalized in the intensive care unit with the diagnosis of Coronavirus Disease-19 (COVID-19) and transfused convalescent plasma based on timing of treatment. Methods: Patients administered 200 mL of convalescent plasma were analysed retrospectively. Based on symptoms’ onset, pa- tients were divided into two groups as early (≤ 7 days) and late (> 7 days) plasma treatment groups. Patients’ characteristics, comorbi- dities, treatments, laboratory (pre-transfusion, day 1 and day 3 af- ter transfusion) and outcome were evaluated according to groups. Results: A total of 152 patients matched criteria. There was no difference between the early (n=82) and late (n=70) treatment groups in terms of demographic characteristics, comorbidities, treatments, outcomes. Ferritin levels were higher in the early tre- atment group than in the late treatment group on before transfu- sion and day 1 (p=0.023, p=0.015). C reactive protein value was lower in the late treatment group on day 3 (p=0.011). Compa- ring the rate of change between day 1 and day 3 of treatment, it was observed that the changes in ferritin and fibrinogen values were higher in the late group than in the early group (p=0.014, p=0.049). There was no difference between the groups in other laboratory values and outcome. Conclusion: In our study, we observed that the timing of convales- cent plasma had no significant effect on outcome. However, more evidence was needed to prove the difference in laboratory results.
