Nutritional support is an effective strategy to restore or maintain nutritional status, to reduce clinical complications, hospitalization period and the morbidity/mortality risk of hospitalized patients. So, a good marker is important to evaluate the nutritional support. Objectives: This study aims to evaluate the evolution of transthyretin levels in patients receiving parenteral nutrition (PN) during 14 days. Design & methods: Longitudinal study of 88 hospitalized patients. The assessments and samples were taken during the first 72 h (T0), on the 7th day (T7) and 14th day (T14) of PN. This study was approved by the Ethics Committee of the School of Medical Sciences at UNICAMP (No 538/2011). Results: The C-reactive protein (CRP) levels were high and albumin and transthyretin levels were low at baseline. From T0 to T14, only transthyretin increased (p = 0.03). According to the receiver operation characteristic (ROC) curve, we found that the transthyretin had some improvement when the CRP levels were less than 10.4 mg/dl (T7). According to the CRP/albumin ratio, all patients classified as without risk for complications were discharged from the hospital. In addition, we observed that patients with transthyretin reduction had a concomitant higher risk for complications according to their ratio CRP/albumin (p = 0.03). Conclusions: CRP/albumin ratio was associated with the evolution of transthyretin levels. Transthyretin values showed significant improvement in the 14 days of PN. Especially, less inflamed patients (ie CRP less than 10.4 mg/dl) improved their transthyretin levels. So, CRP value at day 7 that predicts the transthyretin and transthyretin is a good biomarker for classification of nutritional support and clinical complications risk in patients receiving PN.
