Adults with cirrhosis who underwent TIPS creation at 9 U.S. hospitals from 2010 to 2015 were included in this retrospective analysis. Change in platelets from before TIPS to 4 months after TIPS creation was characterized. Logistic regression was used to assess factors associated with top quartile percentage platelet increase after TIPS. Subgroup analyses were performed among patients with a pre-TIPS platelet count of ≤50 ×109/L.
A total of 601 patients were included. The median absolute change in platelets was 1 × 109/L (-26 × 109/L to 25 × 109/L). Patients with top quartile percent platelet increase experienced ≥32% platelet increase. In multivariable analysis, pre-TIPS platelet counts (odds ratio [OR], 0.97 per 109/L; 95% CI, 0.97-0.98), age (OR, 1.24 per 5 years; 95% CI, 1.10-1.39), and pre-TIPS model for end-stage liver disease (MELD) scores (OR, 1.06 per point; 95% CI, 1.02-1.09) were associated with top quartile (≥32%) platelet increase. Ninety-four (16%) patients had a platelet count of ≤50 × 109/L before TIPS. The median absolute platelet change was 14 × 109/L (2 × 109/L to 34 × 109/L). Fifty-four percent of patients in this subgroup were in the top quartile for platelet increase. In multivariable logistic regression, age (OR, 1.50 per 5 years; 95% CI, 1.11-2.02) was the only factor associated with top quartile platelet increase in this subgroup.
TIPS creation did not result in significant platelet increase, except among patients with a platelet count of ≤50 × 109/L before TIPS. Lower pre-TIPS platelet counts, older age, and higher pre-TIPS MELD scores were associated with top quartile (≥32%) platelet increase in the entire cohort, whereas only older age was associated with this outcome in the patient subset with a pre-TIPS platelet count of ≤50 × 109/L.
