ABSTRACT
BACKGROUND: SARS-COV 2 turned in a global epidemic since January 2020. It is able to directly stimulate the release of proinflammatory cytokines (cytokine storm) and, affecting enterocytis, dysregulates intestinal permeability likewise Inflammatory Bowel Diseases. According to Guidelines, nutritional support in COVID-19 patients is relevant in a perspective of a fast recovery. Aim of this study is to propose in SARS-COV2 patients an early nutritional support using a polymeric-TGF-beta2 containing formula, with immunoregulatory properties specific for bowel disease, evaluating its effects on systemic inflammation and protein energy malnutrition. METHOD(S): COVID-19 patients hospitalized in Santa Maria Hospital of Terni and in Madonna delle Grazie Hospital of Matera (March-December 2020) were enrolled. The protocol consists in supplying 150 gr of nutritional formula powder (750 kcal/day). Values of serum prealbumin, transferrin, C-reactive protein and Lymphocyte count were collected at baseline and every week. Data were compared to a untreated sample of inpatients. RESULT(S): TGF-beta2 containing formula use seems to be associated to a lower needing and longer time free from steroid therapy, increasing of prealbumin and transferrin values and overall with a better outcome in exposed patients;higher values of serum prealbumin seemed to be associated with lower CRP. It does not induce gastrointestinal discomfort or worsen gastrointestinal symptoms. CONCLUSION(S): TGF-beta2 containing formula represents a valid nutritional support in COVID-19, preventing sarcopenia associated to hypercatabolic status and modulating inflammatory response probably thanks to specific properties of its nutritional components. This is only a preliminary observation: further investigations are on-going, involving several Italian Centers. Copyright © 2022-IOS Press. All rights reserved.
