The aim of this study is to assess the efficacy and efficiency of a nutraceutical from sea urchin eggs with Echinochrome A in the inflammation of tissues in subjects with long Corona Virus (COVID) syndome
This is a double-blind placebo-controlled study in approximately 60 subjects with long COVID syndrome. After being informed about the study and potential risks, all subjects giving written informed consent will be screened to assess initial respiratory, cardiological inflammatory, neurological and emotional conditions. Prior to the first administration of the treatment, subjetcs will be randomized to receive three vials of the Dietary Supplement with sea urchin eggs extract with presence of the antioxidant Echinochrome A or placebo. According with the ACRO suggestions this study is focus on the patients. Subjects will be monitor by a Telemedicine platform called SkyMed developed for this study to assess their health daily and will have a weekly virtual meeting with a counselors to assess emotional state. Subjects will attend tp the Hospital, at the beggining of the study, and after finishing the vials of the Dietary Supplement (30, 60 and 90 days). Clinical, cardiological, neumonological and neurological studies will carried out to asses the systemic health as well as the quality of life indicators. Inflammation, trombolotic and inmune indicators will be assess in blood samples (basal, 30, 60 and 90 days). The main objetivec behind this clinical trial is to diminish ROS in the cells, enhance gluthation pathways and diminish cellular inflammation. Echinochrome A is a powerfull marine poliphenol with known antioxidant activity found in the eggs, shells and spines of sea urchins, that had been use in eastern medicien for a long time. Powder of sea urchin eggs are mention in Materia Medica back far 1647 as a powerfull anti inflamation agent.

Change of lung capacity over four times (baseline, 4 weeks, 8 weeks, 12 weeks) assessed during spirometry.
The main variables of forced spirometry that are measured are the forced vital capacity (FVC) and the forced expiratory volume in the first second (FEV1). The FVC represents the maximum volume of air exhaled in a maximal effort expiratory maneuver, initiated after a maximal inspiration maneuver, expressed in liters. FEV1 corresponds to the maximum volume of air exhaled in the first second of the FVC maneuver, also expressed in liters. In turn, the FEV1/FVC ratio shows the relationship between both parameters.

After five repetitions of free-recall, a second "interference" list (List B) is presented in the same manner, and the participant is asked to recall as many words from List B as possible. After the interference trial, the participant is immediately asked to recall the words from List A, which she or he heard five times previously. After a 20 min delay, the participant is asked to again recall the words from List A. After this "delayed recall" task, a list of 50 words is presented containing all of the words from Lists A. The score given for each trial is the total number of words recalled. Normal scores are 6 words hit on the first trial and 12 or 13 on the fifth trial.

On average a person is not capable of retaining more than 7 pieces of information. This means that when the longest repeated sequence is 7, the participant reached level 7. The test was assessed in forward orders of the digits.

Changes in concussion over time-points (baseline, 4 weeks, 8 weeks, 12 weeks) via king figure method.
Demonstration and test cards for the King-Devick test, a candidate rapid sideline screening for concussion based on speed of rapid number naming. To perform the King-Devick test, participants are asked to read the numbers on each card from left to right as quickly as possible, but without making any errors. Following completion of the demonstration card (upper left), subjects are then asked to read each of the three test cards in the same manner. The times required to complete each card are recorded in seconds using a stopwatch. The sum of the three test card time scores constitutes the summary score for the entire test, the King-Devick time score. Numbers of errors made in reading the test cards are also recorded; misspeaks on numbers are recorded as errors only if the subject does not immediately correct the mistake before going on to the next number.
