Change in Platelet Count after Transjugular Intrahepatic Portosystemic Shunt Creation: An Advancing Liver Therapeutic Approaches (ALTA) Group Study.

PURPOSE: To evaluate recovery of platelet count after transjugular intrahepatic portosystemic shunt (TIPS) creation and patient factors predicting platelet recovery after TIPS creation. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Psychological contributors to the frail phenotype: The association between resilience and frailty in patients with cirrhosis.

We examined whether a key psychological trait-resilience, defined as one's ability to recover quickly from difficulties-contributes to the frail phenotype in patients with cirrhosis. Included were 300 adult patients with cirrhosis who underwent outpatient physical frailty testing using the Liver Frailty Index and resilience testing using the Connor-Davidson Resilience Scale (CD-RISC). The Liver Frailty Index was categorized as robust, prefrail-robust, prefrail-frail, and frail; CD-RISC was categorized using population norms as: least, less, more, and most resilient. Linear regression was used to assess factors associated with frailty (by the Liver Frailty Index per 0.1 unit change). Among the most resilient, only 10% were frail; among the least resilient, 29% were frail. In univariable analysis, resilience was strongly associated with the Liver Frailty Index (coef = -0.13 per point increase; 95% confidence interval [CI], -0.20 to -0.60; P < .001) and remained significantly associated with frailty in multivariable adjustment (coef = -0.13, 95% CI -0.19 to -0.07; P < .001). Low resilience is strongly associated with the frail phenotype in patients with cirrhosis. Given that resilience is modifiable, our data suggest that effective interventions to mitigate frailty should include strategies to build resilience in patients with low baseline resilience.
