Association between platelet indices and non-alcoholic fatty liver disease: a systematic review and meta-analysis

Metabolic Dysfunction-Associated Steatotic Liver Disease in Type 2 Diabetes Patients-The Relationship with Platelets Indicators

Background and Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is an important chronic liver disease with major health risks, especially in the presence of T2DM, but the pathophysiology of this condition is not fully understood. This study aimed to investigate the platelet hematometric indices in patients with T2DM and MASLD. Materials and Methods: Demographic and medical (including anthropometric) data were collected from 271 participants, from whom blood samples were also drawn in fasting conditions for complete blood count, liver and metabolic panel, ferritin, haptoglobin, creatinine, and fibrosis markers. The correlations of main platelet parameters with clinical and laboratory data were investigated by bivariate and multiple regression analyses. Results: The median platelets number was 235·103/μL, and thus, the study population was divided into two subgroups: with higher and lower numbers (group 1 (mean): 286.38 ± 43.29·103/μL and group 2 (mean): 188.12 ± 39.77·103/μL). Despite similar BMIs, group 2 had higher fatty liver index (FLI) (84.44 ± 18.04 vs. 79.85 ± 17.98; p = 0.0088) and insulin resistance (HOMA-IR: 3.16 ± 1.50 vs. 2.63 ± 1.31; 0.0008), higher direct bilirubin, transaminases, uric acid, and ferritin concentrations. Higher percentages of males and subjects with HOMA-IR values >2.5 were accounted for in this group. In the multiple regression analyses, the platelet count and plateletcrit (PTC) correlated independently with sex, leucocyte count, HOMA-IR, and bilirubin concentrations (p < 0.0001). The platelet distribution width (PDW) was positively correlated with insulin resistance in two separate analyses (β = 0.060; p = 0.0004, and β = 0.052; p = 0.0025), and with GGT, while the mean platelet volume presented a weak but significant positive association with FLI. Patients with higher HOMA-IR had higher PDW and a lower platelet count and PTC. Conclusions: Male patients with T2DM and MASLD had lower platelet count and PTC and larger PDW. Higher insulin resistance was associated with lower platelet count and PTC and higher PDW.

Mean platelet volume is associated with periodontitis: a cross-sectional study

BACKGROUND

It is uncertain if mean platelet volume and periodontitis are related. The objective of this study was to examine the association between levels of mean platelet volume and moderate/severe periodontitis in adult persons who inhabit the U.S.

METHODS

We screened 6,809 people from the National Health and Nutrition Examination Survey (NHANES 2009-2012). Mean platelet volume was measured in the Mobile Examination Centers (MECs) using the Beckman Coulter analyzer. The category of periodontitis was defined by the CDC/AAP using clinical periodontal parameters. Multiple logistic regression models were employed to examine the distribution for covariate differences across the various independent groups. Four models were employed to examine the relationship between mean platelet volume level and periodontitis. Smoothed curve fitting was utilized to confirm the linearity of the relationships. To determine the impact of factors on the connection between MPV and periodontitis, subgroup analysis and interaction testing were utilized.

RESULTS

Results from the multiple logistic regression analysis indicate a significant association between moderate/severe periodontitis and the mean platelet level, even after considering any potential confounding variables (OR = 1.090, 95% CI: 1.019-1.166, P-value = 0.01211). Additionally, those in the upper tertile of mean platelet volume levels had a 21.6% higher probability of developing periodontitis when compared with those in the least tertile of mean platelet levels (OR = 1.216, 95% CI:1.052-1.406, P-value = 0.00816). Moreover, it showed a positive correlation between mean platelet volume (MPV) and moderate/severe periodontitis. Subgroup analyses indicated a positive association between the level of mean platelet volume and moderate/severe periodontitis among individuals who were under 60 years of age, had low income, were obese, never smoked, were heavy drinkers, had hypertension, and had no cardiovascular disease (p < 0.05). However, none of the subgroups exhibited significant interactions (p for interaction > 0.05).

CONCLUSION

A correlation has been found between mean platelet volume levels and periodontal disease in individuals residing in the United States.
