BACKGROUND: Atrial fibrillation (AF) is a common cardiac rhythm disorder associated with hemodynamic disruptions and thromboembolic events. While antiarrhythmic drugs are often recommended as the initial treatment, catheter ablation has emerged as a viable alternative. However, the recurrence of AF following ablation remains a challenge, and there is growing interest in exploring inflammatory markers as predictors of recurrence. METHODS: This retrospective, cross-sectional analysis included 249 patients who underwent cryoablation for paroxysmal AF. The relationship between the ‘C-reactive protein (CRP) to albumin ratio (CAR)’ and AF recurrence was examined. RESULTS: Two hundred and forty-nine patients with paroxysmal non-valvular atrial fibrillation were included. They were divided into two groups: those without recurrence (Group 1) and those with recurrence (Group 2). Significant differences were observed in age (57.2 ± 9.9 vs. 62.5 ± 8.4, p = 0.001) and left atrial size (4.0 ± 0.5 vs. 4.2 ± 0.7, p = 0.001) between the two groups. In blood parameters, significant differences were found in CRP (5.2 ± 1.3 vs. 9.4 ± 2.8, p < 0.001) and neutrophil counts (5.1 ± 2.2 vs. 6.7 ± 3.6, p = 0.001). In univariate regression analysis, age (OR: 1.058, CI: 1.024–1.093, p = 0.001), WBC count (OR: 1.201, CI: 1.092–1.322, p < 0.001), neutrophil count (OR: 1.239, CI: 1.114–1.378, p = 0.001), CAR (OR: 1.409, CI: 1.183–1.678, p < 0.001), and left atrial diameter (OR: 0.968, CI: 0.948–0.989, p = 0.002) showed significant associations with AF recurrence. CONCLUSIONS: Inflammation plays a crucial role in the initiation and progression of AF. This study demonstrated that along with age, the CAR can serve as an independent predictor of AF recurrence following cryoablation.

Hypertriglyceridemia is a metabolic condition with multifactorial etiology that may cause life-threatening complications, such as pancreatitis. In pregnant women, hypertriglyceridemia may be secondary to physiological changes during pregnancy or may be exacerbated by medications. The combination of tacrolimus and estradiol is sometimes used in in vitro fertilization (IVF) for women with a history of recurrent implantation failure. This case report discusses a case of acute pancreatitis caused by hypertriglyceridemia secondary to the use of tacrolimus and estradiol.

Otozomal dominant polikistik böbrek hastalığı (ODPBH) en sık görülen kalıtsal böbrek hastalığıdır ve olguların %85’inde PKD1, %10-15’inde ise PKD2 gen mutasyonu görülmektedir. ODPBH da renal 3',5'-siklik adenozin monofosfat ()seviyeleri artarak kist oluşumunda önemli rol oynar. Vazopressin üretiminin, salgılanmasının veya etkisinin sürekli baskılanması kist oluşumunu engelleyerek böbrek fonksiyonunun korunmasını sağladığı gösterilmiştir. Tolvaptan kısa etkili V2R inhibitörü olarak etki eder ve vazopressinin etkisini tamamen bloke ederek kist gelişimini azaltır. Bu vakada ODPBH’ta hastalık progresyonu yavaşlatmak amacıyla tolvaptan tedavisi kullanırken eşzamanlı KVH ve dislipidemi nedeniyle statin tedavisi başlanmış ancak takiplerde hepatotoksisite gelişmesine bağlı tolvaptan tedavisinin aksatılmadan devam edilmesi için statin yerine ezetimib monoterapisi tercih edilen hasta sunulmuştur.
