Clinical Trials
1 Lessening Organ Dysfunction With VITamin C (LOVIT)
LOVIT is a multicentre concealed-allocation parallel-group blinded randomized controlled trial to ascertain the effect of high-dose intravenous vitamin C compared to placebo on mortality or persistent organ dysfunction at 28 days in septic intensive care unit patients. Patients with COVID-19 are considered eligible for this study.
NCT03680274 Sepsis Vitamin C Intensive Care Unit COVID-19 Pandemic Coronavirus Drug: Vitamin C Other: Control MeSH:Coronavirus Infections
Primary Outcomes
Description: Defined as death or dependency on mechanical ventilation, renal replacement, or vasopressors
Measure: Number of deceased participants or with persistent organ dysfunction Time: Both assessed at 28 daysSecondary Outcomes
Description: Persistent organ dysfunction-free days in intensive care unit
Measure: Number of participants with persistent organ dysfunction-free days in intensive care unit Time: Up to day 28Description: Mortality at 6 months
Measure: Number of participants deceased at 6 months Time: 6 monthsDescription: Assessed by the questionnaire EuroQol-5D (EQ-5D-5L). The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'.
Measure: Score of health related quality of life in 6-month survivors Time: 6 monthsDescription: Assessed by serum lactate concentration
Measure: Global tissue dysoxia Time: Days 1, 3, 7Description: Assessed by the Sequential Organ Failure Assessment (SOFA) score. Used to track a person's status during the stay in an intensive care unit to determine the extent of a person's organ function or rate of failure. The score is based on 6 different sub-scores, one each for the respiratory (PaO2/FiO2 mmHg), cardiovascular (mean arterial pressure OR administration of vasopressors required), hepatic (liver bilirubin (mg/dl) [μmol/L]), coagulation (platelets×103/µl), renal (kidneys creatinine (mg/dl) [μmol/L] (or urine output)) and neurological (Glasgow coma scale). The sub-score of eah system ranges from 0 (best) to +4 (worst).
Measure: Organ function (including renal function) Time: Days 1, 2, 3, 4, 7, 10, 14, 28Description: Assessed by interleukin-1 beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP)

Measure: Vitamin C plasma concentration Time: 6th dose of vitamin C (second dose on day 2) at time 0 (immediately prior to the dose) and then after administration at times 1 hour, 2 hours, 4 hours and 6 hours (Pharmacokynetic substudy)2 Use of Ascorbic Acid in Patients With COVID 19
Different studies showed that ascorbic acid (vitaminC) positively affects the development and maturation of T-lymphocytes, in particular NK (natural Killer) cells involved in the immune response to viral agents. It also contributes to the inhibition of ROS production and to the remodulation of the cytokine network typical of systemic inflammatory syndrome. Recent studies have also demonstrated the effectiveness of vitamin C administration in terms of reducing mortality, in patients with sepsis hospitalized in intensive care wards. Given this background, in the light of the current COVID-19 emergency, since the investigators cannot carry out a randomized controlled trial, it is their intention to conduct a study in the cohort of hospitalized patients with covid-19 pneumonia, administering 10 gr of vitamin C intravenously in addition to conventional therapy.

Healthcare workers (HCW) at risk of Covid-19 will have baseline serology for SARS-CoV-2 to see if they are already immune to Covid-19. HCW will get baseline assessment and if meeting inclusion criteria and no exclusion criteria they will be randomized in a 2:1 ratio to hydroxychloroquine or Vitamin C on a weekly basis for three months. Subjects will complete daily diary of symptoms and temperature, and will have repeat SARS-CoV-2 serology at 6 weeks and 3 months to determine seroconversion.
