Abstract

Objective: To investigate the effect of targeted temperature management (TTM) on pyroptosis in patients who achieved return of spontaneous circulation (ROSC) following cardiopulmonary resuscitation (CPR) after cardiac arrest (CA). Methods: This study included 30 patients with CA in whom CPR was initiated within the first 15 minutes after arrest and lasted no longer than 60 minutes, as well as 30 age- and sex-matched healthy volunteers. The study was conducted at Harran University Medical Faculty Hospital between 2021 and 2022. The patient group received TTM therapy for 48 hours. Exclusion criteria were age <18 years, pregnancy, coagulopathy, thrombocytopenia, uncontrolled arrhythmia, end-stage disease, pre-existing neurological disease with cognitive impairment, persistent cardiogenic shock, suspected or confirmed acute intracerebral hemorrhage/acute stroke, and malignancy. Blood samples were collected from patients at three time points: at initiation of TTM (baseline), at 24 hours, and at 48 hours. Serum levels of NLRP3, caspase-1, gasdermin-D, and IL-1β were measured. Results: Serum NLRP3, caspase-1, gasdermin-D, and IL-1β levels were significantly higher in the patient group compared with the control group at all time points. Although not reaching statistical significance, NLRP3, caspase-1, and gasdermin-D levels showed a decreasing trend during the 48-hour follow-up after TTM compared with baseline values. Conclusion: Pyroptosis markers were significantly elevated following cardiac arrest compared with healthy controls. Although the reductions observed after TTM did not reach statistical significance, a downward trend in pyroptosis markers was noted during treatment.

Özet

Amaç: Kardiyopulmoner resüsitasyon (KPR) sonrası spontan dolaşımı geri dönen hastalarda hedefe yönelik sıcaklık yönetiminin (TTM) Piroptoz üzerindeki etkisini araştırmak. Yöntem: 2021 ve 2022 yılları arasında Harran Üniversitesi Tıp Fakültesi Hastanesi’nde, Kardiyak arrest (KA) sonrası ilk 15 dakika içinde başlatılan ve toplamda 60 dakikadan fazla sürmeyen KPR uygulanan 30 KA hastası ile yaş ve cinsiyet açısından eşleştirilmiş 30 sağlıklı gönüllü çalışmaya dahil edildi. Çalışma grubu 48 saat boyunca TTM tedavisi aldı. 18 yaşından küçük hastalar, gebelik, koagülopati, trombositopeni, kontrolsüz aritmi, son dönem hastalıklar, bilişsel bozukluk öyküsü olan önceki nörolojik hastalık, persistan kardiyojenik şok, şüpheli veya doğrulanmış akut intraserebral kanama/akut inme ve malignite olan hastalar çalışmadan hariç tutuldu. Çalışma grubundan üç kez kan örneği alındı: TTM’nin başlangıcında, TTM’nin 24. saatinde ve TTM’nin 48. saatinde. NLRP3, kaspaz-1, gasdermin-D ve IL-1B proteinleri ölçüldü. Bulgular: NLRP3, kaspaz-1, gasdermin D ve IL-1B düzeylerinin tüm zaman noktalarında kontrol grubuna göre denek grubunda anlamlı olarak daha yüksek olduğu saptandı. Öte yandan, istatistiksel olarak anlamlı olmasa da, NLRP3, kaspaz-1 ve gasdermin-D düzeyleri, 48 saatlik takip süresi boyunca TTM tedavisi sonrası test grubunda başlangıç değerlerine kıyasla azaldı. Sonuç: Kalp durması sonrasında piroptozis belirteçleri, sağlıklı kontrollere kıyasla anlamlı derecede artmıştır. TTM sonrasında gözlemlenen azalmalar istatistiksel olarak anlamlı olmasa da, tedavi sırasında piroptozis belirteçlerinde aşağı yönlü bir eğilim kaydedilmiştir
