Article Abstract
Objective: Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse perinatal outcomes. Accurate and timely diagnosis is essential to minimize maternal and fetal risks. The standard diagnostic method-measurement of fasting serum bile acids (BA)-poses challenges due to limited availability, high cost, and delayed results. This study aimed to evaluate the diagnostic and prognostic utility of the aspartate aminotransferase to platelet ratio index (APRI) and the De Ritis ratio in ICP.
Methods: This retrospective case-control study included 238 pregnant women, categorized into three groups: mild ICP (n = 62), severe ICP (n = 57), and healthy controls (n = 119). Demographic, biochemical, and perinatal outcomes were compared among the groups. APRI and De Ritis ratios were calculated and analyzed using receiver operating characteristic (ROC) curves and correlation analyses.
Results: APRI levels were significantly elevated in ICP patients and demonstrated strong diagnostic performance for identifying ICP (cut-off: 0.295; AUC = 0.842). The De Ritis ratio was significantly lower in both ICP groups compared with controls (cut-off: 1.097; AUC = 0.770). APRI also correlated with disease severity (cut-off: 0.615 for severe ICP; AUC = 0.868). Higher APRI values were associated with increased neonatal intensive care unit (NICU) admissions and lower gestational age and birth weight.
Conclusions: APRI and De Ritis ratios are simple, inexpensive, and non-invasive markers that may aid in the diagnosis and severity assessment of ICP. They could serve as useful alternatives in clinical settings where BA testing is limited or unavailable.

The clinical implementation of noninvasive tests for liver fibrosis assessment has attracted increasing attention, particularly for diagnosing advanced fibrosis (≥F3). This observational study aimed to evaluate the stratification accuracy of nine direct and seven indirect biomarkers across four etiologies: chronic hepatitis B (CHB), chronic hepatitis C (CHC), alcoholic liver cirrhosis (ALC), and nonalcoholic liver cirrhosis (NALC). : Our study was conducted on 116 participants, including 96 with chronic liver disease (16 CHB, 15 CHC, 49 ALC, and 16 NALC) and 20 healthy controls.

The implementation of easily accessible prognostic biomarkers for patients with COVID-19 remains an important area of clinical research. In this large monocentric study at a German tertiary care hospital, we determined the prognostic performance of different liver scores in 605 patients with COVID-19. We evaluated the Fibrosis-4 (FIB-4) index, the Aspartate Aminotransferase-to-Platelet Ratio Index (APRI), the Model for End-Stage Liver Disease (MELD) score, and the De Ritis ratio (DRR; AST/ALT ratio).

Article Synopsis
- Neoadjuvant and adjuvant therapies are becoming increasingly important in treating cutaneous melanoma (CM), but there is still a need for better prognostic tools to identify patients at high risk.
- Recent evidence suggests that liver scores could serve as potential prognostic indicators across various tumor types, prompting an investigation into their relevance for CM prognosis.
- A study involving 423 patients demonstrated that while tumor thickness and ulceration were key predictors of survival across all stages, liver scores like the APRI showed significant associations with survival outcomes specifically in earlier stages (I and II) of melanoma.

Objective: Haematological and liver fibrotic markers could be appreciably utilized for effective monitoring of Chronic Hepatitis B viral (HBV) infection, thereby increasing patient's treatment outcome. The objective of this study was to assess the applicability of complete blood count (CBC) and non-invasive liver-fibrotic indices as markers of prognostic outcome and monitoring in HBV infections.
Results: Significant differences in levels of white cell and differentials counts, red blood cell count, hemoglobin indices, and platelet indices were observed between HBV-infected patients (cases) and uninfected persons (controls).
