Background and Objectives: Vitamin D supplementation plays a key effect in lowering cytokine storms among COVID-19 patients by influencing the activity of the renin-angiotensin system and the production of the angiotensin-2 converting enzyme. The study was conducted to explore the effect of high-dose intramuscular vitamin D in hospitalized adults infected with moderate-to-severe SARS-CoV-2 in comparison with the standard of care in the COVID-19 protocol. Materials and Methods: Two groups of patients were compared in this prospective randomized controlled trial as the vitamin D was administered orally to group 1 (alfacalcidol 1 mcg/day) and intramuscularly to group 2 (cholecalciferol 200,000 IU). One hundred and sixteen participants were recruited in total, with fifty-eight patients in each group. Following the Egyptian Ministry of Health’s policy for COVID-19 management, all patients received the same treatment for a minimum of five days. Results: A significant difference was recorded in the length of hospital stay (8.6 versus 6.8 days), need for high oxygen or non-invasive mechanical ventilator (67% versus 33%), need for a mechanical ventilator (25% versus 75%), clinical improvement (45% versus 55%), the occurrence of sepsis (35% versus 65%), and in the monitored laboratory parameters in favor of high-dose vitamin D. Moreover, clinical improvement was significantly associated with the need for low/high oxygen, an invasive/non-invasive mechanical ventilator (MV/NIMV), and diabetes, while mortality was associated with the need for MV, ICU admission, atrial fibrillation, chronic obstructive pulmonary disease, asthma, and the occurrence of secondary infection. Conclusions: Our study showed that high-dose vitamin D was considered a promising treatment in the suppression of cytokine storms among COVID-19 patients and was associated with better clinical improvement and fewer adverse outcomes compared to low-dose vitamin D.
Background
The treatment of severe cases of COVID‐19 disease remains a dilemma so far, because there is no approved therapy for it. This study aimed to estimate the therapeutic efficacy of tocilizumab and its role in reducing the need for mechanical ventilation, length of hospital stay, mortality rate for these cases.
Method
The study included 25 adult patients with confirmed severe COVID‐19 infection. Treatment of all patients followed Egyptian Ministry of Health COVID‐19 protocol in addition to tocilizumab IV (400‐800 mg) as a single dose and then the dose was repeated after at least 12 hours and up to 24 hours from the previous dose. All laboratory and clinical parameters were assessed before and within 24 hours after tocilizumab administration.
Results
After receiving TCZ, all patients showed significantly lower median IL 6, LDH, CRP, ferritin , TLC at P < .001, and D‐Dimer at P = .223 than their baseline levels. Also, the number of patients who required mechanical ventilation decreased from 11 to 8. Only five patients died after TCZ treatment. A moderate correlation was found between therapeutic failure and death outcomes and mechanical ventilation need at baseline. The median days of hospitalisation (IQR) were 10 (6‐16).
Conclusion
Tocilizumab treatment in patients with severe COVID‐19 is safe and has significant therapeutic effects and a significant role in the improvement of all laboratory parameters. Also TCZ plays a significant role in the reduction of the length of stay in hospital and ICU, need for mechanical ventilation, and mortality rate.
Objective
This study aimed to assess the correlation between body mass index (BMI) and plasma lipid profile levels in mild and severe COVID-19 patients.
Method
This was a prospective, observational, cohort study, conducted in a medical referral center specializing in management of COVID-19 cases. Patients were divided into two groups according to infection severity (mild and severe). Blood samples were obtained from all patients who tested positive to a PCR test for measuring biochemical and inflammatory markers such as lactate dehydrogenase, ferritin, C-reactive protein, and
d
-dimer, as well as lipid profile, including total cholesterol, triacylglycerols, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), which were analyzed and compared between the two groups. Pearson’s correlation was used to assess the correlation between BMI and plasma lipid profile among mild and severe cases.
Results
The levels of plasma triacylglycerols,
d
-dimer, lactate dehydrogenase, ferritin, and C-reactive protein with severe infection were significantly different between patients with mild and severe COVID-19 symptoms (
p
= 0.036, 0.03, 0.001, 0.014, and 0.006, respectively). A positive correlation between BMI and triglyceride levels was observed only in the severe infection group. However, HDL-C was negatively correlated with BMI.
Conclusion
A routine lipid profile test might help as a marker of inflammation and risk stratification in patients with COVID-19. Especially in middle- or low-income countries, the test can rapidly help clinicians to delineate prognostic measures and hence management and treatment plans for this disease as the levels of the lipid profile were correlated with the patients’ BMI and infection severity.
