Against the above background, Di Shen, Graduate School, Xinjiang Medical University, Urumqi, Xinjiang, People’s Republic of China, and colleagues explore the link between inflammatory indices and MAFLD in hypertensive patients while evaluating the predictive accuracy of these indices for the condition.
For this purpose, the researchers conducted a cross-sectional analysis of 34,303 hypertensive patients from a Chinese hospital registry. MAFLD was diagnosed using metabolic dysfunction criteria, and evidence of hepatic steatosis was confirmed through imaging. Inflammatory indices, including the monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammatory response index (SIRI), systemic immune-inflammation index (SII), and aggregate index of systemic inflammation (AISI), were calculated using complete blood counts.
The relationship between these indices and MAFLD was assessed using multivariable logistic regression, adjusting for potential confounders. The indices' diagnostic performance was evaluated using receiver operating characteristic (ROC) curves and area under the curve (AUC) calculations.
The study revealed the following findings:
- Patients with MAFLD had significantly higher levels of all inflammatory indices than those without MAFLD.
- After adjusting for confounders, each standard deviation increase in AISI, SIRI, and SII was associated with a 74%, 62%, and 58% increased odds of developing MAFLD, respectively.
- The AUC for AISI was 0.659, indicating moderate diagnostic accuracy.
- The AUCs for SIRI and SII were 0.626 and 0.619, respectively.
- NLR, PLR, and MLR showed lower AUCs of 0.593, 0.558, and 0.589, respectively.
The large cross-sectional study highlights a significant link between elevated inflammatory indices and MAFLD in hypertensive patients, with AISI demonstrating the strongest predictive value.
"These findings emphasize the potential of using non-invasive inflammatory biomarkers for MAFLD risk stratification, suggesting the need for further prospective research to explore their clinical applicability," the researchers concluded.
