Risk of reduced platelet counts in patients with nonalcoholic fatty liver disease (NAFLD): a prospective cohort study.

ABSTRACT:

Background

The production of peripheral platelet is mainly regulated by thrombopoietin, which is a glycoprotein hormone predominantly synthesized in the liver. Previously, many studies have reported that there was an inverse correlation between the degree of chronic viral hepatitis and the peripheral platelet count. However, the effect of nonalcoholic fatty liver disease (NAFLD) on the peripheral platelet counts remains unclear.

Methods

With 1303 participants from "The prevention of MS and multi-metabolic disorders in Jiangsu province of China (PMMJS)" cohort study, we investigated the associations between NAFLD and the risk of platelet counts reduction in Chinese adults. The paired-samples T test was used to explore the platelet counts changes between baseline and follow-up. Multivariate logistic regression was used to examine the association between presence of NAFLD and the risk of platelet reduction by calculating the odds ratios (ORs) and 95% confidence interval (CI).

Results

After five years of follow-up, platelet counts were markedly reduced from 220.6?±?42.22 (10⁹/L) at baseline to 208.41?±?40.70 (10⁹/L) at follow-up in NAFLD group (P?9/L) at baseline to 211.8?±?41.65 (10⁹/L) at follow-up in non-NAFLD people (P?=?0.2349). Meanwhile, there was a significant association between NAFLD and the risks of platelet count reduction, even after adjustment for confounding variables (OR: 1.68, 95% CI: 1.06-2.67). Additionally, among the participants with BMI???23 kg/m² and SUA???344.3 ?mol/L, the NAFLD participants have an increased risk of platelet count reduction compared to the persons in non-NAFLD group.

Conclusions

Our present results suggested that NAFLD individuals have an increased risk of platelet counts reduction.
