Background: Acute kidney injury (AKI) frequently affects patients with liver cirrhosis, diagnosed by changes in serum creatinine and urine output. This study aimed to evaluate the diagnostic and prognostic utility of serum cystatin C (Cys C) and angiopoietin 2 (Ang 2) in patients with liver cirrhosis complicated by AKI. Methods: A total of 81 cirrhotic patients with AKI were included. AKI was diagnosed according to Kidney Disease Improving Global Outcomes criteria. All patients were assessed clinically and biochemically. Baseline serum Cys C and Ang 2 were assessed, and patients were prospectively followed‐up to assess patients' and renal survival. Results: Cys C significantly predicted AKI (p < 0.001). Ang 2 (≤179.7 pg/ml) was an independent predictor of mortality in multivariate analysis. Marked ascites and partial pressure of carbon dioxide ≤ 29 were significant predictors of nonrenal recovery. Conclusion: Cys C showed validity AKI diagnosis in cirrhotic patients while Ang 2 was an independent predictor of mortality. [ABSTRACT FROM AUTHOR]

Left ventricular hypertrophy (LVH) is a risk factor of cardiovascular morbidity in dialysis patients. The association between LV mass and carotid intimal medial thickness (CIMT) could be due to increased hemodynamic load in dialysis patients. The relationship between CIMT and LVM indices in hemodialysis (HD) patients was investigated. This is a cross‐sectional study including 65 HD patients, divided into two groups: Group 1 with CIMT ≤ 1 mm (N = 29), Group 2 with CIMT > 1 mm (N = 36). Echocardiographic evaluation of the LVM, CIMT measurement using B‐mode ultrasonography, patients' basic clinical and biochemical data were recorded. Patients with CIMT > 1 mm (Group 2) showed significantly higher LVM, LVM/BSA (body surface area), and LVM/Ht2.7 (height). Regarding linear regression, CIMT was found to be an independent predictor for LVM, LVM/BSA, and LVM/Ht2.7. LVM, LVMI, and LVM/Ht2.7 are significantly elevated in HD patients with CIMT > 1 mm group. CIMT was found to be the independent predictor for LVH in maintenance HD patients. [ABSTRACT FROM AUTHOR]
