Abstract
Sixteen descriptive studies out of 3,126 articles with 4,155 participants included. The frequency of malnutrition in reviewed studies ranged from 17% to 92%. Lower serum albumin was associated with more severe malnutrition in Nutritional Risk Assessment (NRA). Although there was a clear consensus on serum albumin association with malnutrition, there were more controversial results for blood lymphocyte count and other inflammatory indices.

The coronavirus pandemic has created a huge health crisis with significant financial impacts and resource shortcomings
A systematic literature search was conducted to investigate the relationship between nutritional and inflammatory parameters among malnourished COVID-19 patients diagnosed with different nutritional assessment tools, using Medline, Embase, APA PsycINFO, and Cochrane Database of Systematic Reviews via Ovid, CINAHL via Ebsco up to November 08, 2021
All patients were admitted to the hospital, and their diagnosis of COVID-19 was confirmed with RT-PCR
Summary
The coronavirus pandemic has created a huge health crisis with significant financial impacts and resource shortcomings. During this overwhelming situation, appropriate preventive, diagnostic, and therapeutic interventions are crucial. There are considerable nutritional concerns around COVID-19 disease and many new studies paid particular attention to malnutrition screening and micro-macro nutrient requirements among COVID-19 patients [1]. The prevalence of malnutrition reported in different studies varies according to many risk factors, including age, comorbidities, gastrointestinal symptoms of patients, and extended stay in intensive care units [2,3]. There is a growing need for nutritional screening.
