Thrombocytopenia (less than 100 × 109/L platelets) presents in around one quarter of patients with nonalcoholic fatty liver disease (NAFLD), the hepatic component of insulin resistance (IR). It is unknown whether IR, by itself, associates with thrombocytopenia. Persons with NAFLD and/or IR were prospectively accrued in the study after February 2018. Insulin resistance was defined by assessing α hydroxybutyrate, lynoleoyl glycerolphosphocoline, oleic acid, and insulin (Quantose IR), whereas the presence of NAFLD was defined by serologic determinations (Fibromax) and liver transient elastography (Fibroscan). In 78 patients with NAFLD, thrombocytopenia was identified in 22 (28%), whereas in 19 persons with IR, 14 (73%) were found to have NAFLD. In persons with IR + NAFLD, thrombocytopenia presented in 9 (64%). In the subset of patients with IR, the prevalence of thrombocytopenia was 52%. There was only 1 patient with IR/without NAFLD who displayed thrombocytopenia. Significant statistical association between NAFLD and thrombocytopenia was found (odds ratio [OR]: = 13, confidence interval [CI]: 1.5-162, P = .05), whereas there was no association between IR and thrombocytopenia (OR = 0.38, CI: 0.06-2.3, P = .61). Insulin resistance, by itself, was not found to be associated with diminished platelet counts. The presence of NAFLD, one of the consequences of IR, seems to be required to lead into thrombocytopenia.
