It has been suggested that the longitudinal evaluation of the MELD score may reflect the progression of liver failure more reliably and therefore be more useful in prognostic assessment. Aim: To assess the prognostic meaning of MELD score modifications in a cohort of cirrhotic patients in whom clinical and bioche mical workup was carried out at least twice during a minimum interval of 30 days . Methods: Forty-six cirrhotic patients were longitudinally evaluated for a med ian follow-up of 365 days. After initial assessment, all the patients had at le ast one clinical and biochemical reevaluation during follow-up, which was perfo rmed no less than 1 month after initial evaluation. MELD was calculated at entry and at second evaluation. △MELD was calculated as MELD at second evaluation mi nus MELD at entry. △MELD/time was calculated as △MELD divided by time elapsed between initial assessment and second evaluation expressed in months. Results: D uring follow-up, 13 patients died (28%). The median interval between clinical evaluations was 120 days. MELD scores at entry (13 ±4 vs 16 ±6, P = 0.0516) an d △MELD (0 ±4 vs 4 ±2, P = 0.0028) were significantly different between patie nts who died and those who survived during the 1-year follow-up. All the patie nts who died during follow-up showed an increase of at least 1 unit in △MELD/t ime (sensitivity = 100%), and all the patients who survived showed a decrease o f more than 1 unit in △MELD/time (specificity = 100%). Conclusions: Longitudin al evaluation of the MELD score provides important prognostic information that s eems to complete the prognostic definition provided by “static" MELD. Prospecti ve studies in larger series are needed to validate the prognostic use of MELD mo difications over time.展开更多
