There is one clinical trial.
Introduction: SARS-CoV2 infection produces severe pneumonia with pulmonary alveolar collapse. There is no specific treatment to date. In experimental models and humans with septic shock, there is a high production of nitric oxide (NO) and reactive nitrogen species (RNS) and can cause multiple organ failure. The administration of antioxidants such as n-acetylcysteine (NAC), vitamin C, melatonin, and vitamin E participate in increasing the intracellular content of GSH, ROS sequestration, protection of the lipids of cell membranes, cytosol proteins, nuclear DNA, mitochondrial and decrease LPO. Justification: as there is no specific antiviral therapy, the therapeutic options are limited, complications and mortality are high; It is intended to evaluate the effect of antioxidants on the storm outcome of the dysregulation of oxidative stress. Hypothesis: It is postulated that adjuvant therapy with antioxidants and Pentoxifylline reduces the use of ventilators in patients with or without septic shock secondary to severe SARS-COV2 pneumonia as decreases lipoperoxidation, and corrects dysregulation of oxidative stress by increasing the antioxidant capacity. Objectives: To evaluate whether it is possible to avoid intubation or decrease assisted mechanical ventilation days, improve oxidative stress dysregulation in patients with SARS-COV2 infection with severe pneumonia with or without septic shock. Methodology: Quasi-experimental, open analytical, prospective, and longitudinal study (before-after). In patients over 18 years of age who are admitted to the CITIBANAMEX Center with or without septic shock secondary to severe SARS-COV2 pneumonia. There will be two groups: 1) patients without septic shock and 2) patients with septic shock secondary to severe pneumonia due to SARS-COV2. A single antioxidant will be applied following the clinical decision tree (NAC, Vit C, Vit E, melatonin) more Pentoxifylline orally or by orogastric tube for a total of 5 days from the start of the protocol. APACHE II will calculate the risk, SOFA, MEXSOFA, measurements of IL-8, vitamin C, NO3 / NO2, LOP, total antioxidant capacity will be carried out at baseline and 48 hours. SOFA will be calculated for seven days, in addition to days of hospitalization, days of mechanical ventilation. It was evaluated 28 days after discharge by telephone.
Description: It will be evaluated whether secondary to SARS-COV2 pneumonia, the outcome of the patient is dead.Measure: Death from any cause Time: From admission to discharge, up to 30 days.
Description: The percentage of patients with SARS-COV2 pneumonia in whom orotracheal intubation was avoided will be evaluated.Measure: Percentage of patients who required orotracheal intubation Time: From admission to discharge, up to 1 week
Description: It will be evaluated if it is possible to reduce the days of mechanical ventilationMeasure: Assisted mechanical ventilation Time: From admission to discharge, up to 1 week
Description: The number of days of stay in the intensive care unit will be evaluated.Measure: Stay in an intensive care unit Time: From admission to discharge, up to 1 week
Description: For the measurement of lipid peroxidation, 50 µL of CH3-OH with 4% BHT plus a phosphate buffer pH 7.4 was added to 100 µL of plasma. The mixture was vigorously vortexed for 5 seconds and subsequently incubated in a water bath at 37 ° C for 30 minutes. 1.5 mL of 0.8 M tribarbituric acid was added to the sample, which was incubated in a water bath with boiling temperature for one hour. After this time and to stop the reaction, the sample was placed on ice; 1 mL 5% KCl was added to each sample, as was 4 mL of n-butanol; The sample was vortexed for 30 seconds and centrifuged at 4000 rpm at room temperature for 2 min. Subsequently, the butanol phase was extracted, and the absorbance at 532 nm was measured. The calibration curve was obtained using tetra ethoxy propane as a standard.Measure: Measure lipoperoxidation in basal and post-therapy samples Time: Baseline and 5 days post-dose
Description: 100 mL of plasma was suspended in 1.5 mL of a reaction mixture prepared as follows: 300 mM of acetate buffer with pH 3.6, 20 mM of ferric chloride hexahydrate, and 10 mM of 2,4,6-Tris-2- Pyridyl-s-triazine dissolved in 40 mM hydrochloric acid in a ratio 10: 1: 1 v / v, respectively. The mixture was vigorously vortexed for 5 seconds. It was incubated at 37 ° C for 15 min in the dark. The absorbance was measured at 593 nm. The calibration curve was obtained using TroloxMeasure: Evaluation of the total antioxidant capacity Time: Baseline and 5 days post-dose
Description: For the measurement of NO3- / NO2-, 100 µl of plasma were added 100 µL of a 10% solution of ZnSO4, 100 µL of 0.5 N NaOH and 700 µl of tridestated water. It was shaken vigorously and centrifuged at 10,000 rpm for 5 minutes. To the resulting supernatant, Griess reagent (200 µL of 1% sulfanilamide and 200 µL of 1% N- (1-naphthyl) ethylenediamine hydrochloride) was added and incubated for 10 min protected from light at room temperature. The coloration developed after incubation was measured at an analytical wavelength of 540 nm in a double beam UV-Vis spectrometer (DW2000, SLM-Aminco, Urbana, Illinois, USA). The calibration curve was performed with a KNO3 stock solution (Spectrum Quality Products, Inc., Gardena CA) in a concentration range from 0.001 nM to 10 nM.Measure: Oxidative and antioxidant stress Time: Baseline and 5 days post-dose
Description: Measurements will be made using the Sequential Organ Failure Assessment (SOFA) every 24 hours. With a minimum score of 0-1 which translates a mortality in initial score and the highest of 0%. The maximum score of more than 14 translates a mortality of 95.2% in the initial evaluation and 89.7% in the highest evaluation.Measure: Effect of antioxidant therapy at the level on organ failure secondary to SARS-COV2 Time: From day 0 to day 7 post antioxidant dose.
Description: Measurements will be made using the Mexico Sequential Organ Failure Assessment (MEXSOFA) every 24 hours. highest evaluation. Patients with an initial MEXSOFA score of 9 points or less calculated during the first 24 hours after admission to the ICU had a mortality rate of 14.8%, while those with an initial MEXSOFA score of 10 points or more had a mortality rate. 40% mortality rate. The MEXSOFA score at 48 h was also associated with mortality: patients with a score of 9 points or less had a mortality rate of 14.1%, while those with a score of 10 points or more had a rate of 50% mortality.Measure: Effect of antioxidant therapy at the level on organ failure secondary to SARS-COV2 Time: From day 0 to day 7 post antioxidant dose.
