Study summary

The novel coronavirus disease (COVID-19) is posing a serious challenge to the health-care systems worldwide, with an enormous impact on health conditions and loss of lives. More than 30 millions of recoveries worldwide were registered at the end of October 2020 with more than 1 million of deaths. As the disease continues to spread, strategies aimed to reduce hospitalization time in sub intensive unit care, thus reducing pressure on health system, but also to reduce some of the pathological features of COVID-19 such as inflammation and the "cytokines storm".

The ketogenic diet is a high fat, low carbohydrate, adequate-protein diet that promotes a physiological ketosis (due to an increase of liver ketone bodies production). High fat, low carbohydrate diets have been shown to reduce duration of ventilator support and partial pressure carbon dioxide in patients with acute respiratory failure. Moreover, the physiological increase in plasma levels of ketone bodies exerts important anti-inflammatory and immunomodulating effects, which may reveal as precious tools to reduce potential adverse outcomes of COVID-19 disease.

The hypothesis of this study is that the administration of a ketogenic diet will improve gas exchange, reduce inflammation, and the duration of hospitalization. The plan is to enrol 28 patients with diagnosis of COVID-19 hospitalized but not in ICU with SPO2 higher than 88%.

What researchers measure

Primary outcomes

  1. inflammation panel: interleukine 6 (IL-6)

    change in IL-6 levels. IL-6 is an inflammatory cytokine. Units: in pg/mL

    Time frame: Daily until patient's hospital discharge, up to 30 days

  2. inflammation panel: tumor necrosis factor alfa (TNFα)

    change in TNFα levels. TNFα is an inflammatory cytokine Units: pg/mL

    Time frame: Daily untilpatient's hospital discharge, up to 30 days

  3. inflammation panel: C-reactive Protein (CRP)

    change in CRP levels. CRP is an non specific index of inflammation Units: in mg/dL

    Time frame: Daily until patient's hospital discharge, up to 30 days

  4. inflammation panel: Erythrocyte sedimentation rate (ESR)

    change in ESR. ESR is an non specific index of inflammationUnits: mm/h

    Time frame: Daily untilpatient's hospital discharge, up to 30 days

  5. coagulation panel: D-Dimer

    change in D-Dimer levels. D-Dimer is a fibrin degradation product. Units: 0.5 mcg/ml Fibrinogen Equivalent Units (FEU)

    Time frame: Daily until patient's hospital discharge, up to 30 days

  6. coagulation panel: fibrinogen

    change in fibrinogen levels. Fibrinogen is a protein involved in forming blood clots in the body. Units: mg/dL

    Time frame: Daily until patient's hospital discharge, up to 30 days

  7. coagulation panel: thrombin clotting time (TT)

    change in TT. TT measures the time it takes for a clot to form in the plasma of a blood sample containing anticoagulant, after an excess of thrombin has been added. Units: seconds

    Time frame: Daily until patient's hospital discharge, up to 30 days

  8. coagulation panel: activated partial thromboplastin time (aPTT)

    change inl aPTT. aPTT measures the overall speed at which blood clots by means of two consecutive series of biochemical reactions. Units: in seconds

    Time frame: Daily until patient's hospital discharge, up to 30 days

  9. Dyspnoea Visual Analog Scale Score (VAS)

    Change in VAS. VAS is a horizontal line, 100 mm in length, and anchored by word descriptors at each end. The VAS dyspnea score uses "no shortness of breath at all" and "maximum shortness of breath". The patient marks on the line the point that they feel represents the perception of their current state

    Time frame: Daily until patient's hospital discharge, up to 30 days

  10. Oxygen saturation

    change in basal peripheral oxygen saturation percentage (%)

    Time frame: Continuosly, daily until patient's hospital discharge, up to 30 days

  11. Evaluation of Lungs conditions

    Anteroposterior chest radiography (CXR)

    Time frame: Change from baseline, Every three days until patient's hospital discharge, up to 30 days

  12. The total hospital stay

    Time from hospital admission to discharge from the hospital.

    Time frame: up to 30 days

Secondary outcomes

    Time frame: Daily until patient's hospital discharge, up to 30 days

  3. mean corpuscular hemoglobin concentration (MCHC)

    change in the amount of hemoglobin per unit volume. Mean cell hemoglobin concentration is the average concentration of hemoglobin in a given volume of blood. Unites: g/dl of red blood cells

    Time frame: Daily until patient's hospital discharge, up to 30 days
