Conditions

Post-COVID syndrome Infections and Infestations

Interventions

This study tests treatment with Omega 3 fatty acid lipid mediators. It is designed as a randomized, double-blind, placebo-controlled trial, with four parallel supplement groups to assess the efficacy
it is a pilot study that aims to determine the effect of increasing food supplement doses. Three different amounts of the supplement (daily use of 500, 1500 and 3000 mg) will be tested and controlled

Design outcomes

Primary

MeasureTime frame
The following primary outcome measures are assessed using lipid mediator laboratory analyses at baseline, 4 and 12 weeks of use: 1. Blood samples and analytics of Polyunsaturated fatty acids: EPA, DHA, ARA, DPA. 2. Monohydroxylated specialized pro-resolving mediators (SPMs): 17-HDHA, 18-HEPE, 14-HDHA. SPMs: Resolvins (RvE1, RvD1, RvD2, RvD3, RvD4, RvD5), Maresins (MaR1, MaR2), Protectins (PD1, PDX), Lipoxins (LXA4, LXB4. 3. Pro-inflammatory eicosanoid lipid mediators: Prostaglandins (PGE2, PGD2, PGF2a.), Thromboxanes (TxB2), Leukotrienes (LTB4)

Secondary

MeasureTime frame
1. Fatigue measured using the Fatigue Severity Scale (FSS) test from at baseline, visit 2 (4th week of treatment, day 28) and to the end of the study (day 84 of treatment) 2. Dyspnea measured using the Modified Medical Research Council (mMRC) Dyspnea Scale at baseline, visit 2 (4th week of treatment, day 28) and to the end of the study (day 84 of treatment)
