ABSTRACT
A vast majority of COVID-19 patients experience fatigue, extreme tiredness and symptoms that persist beyond the active phase of the disease. This condition is called post-COVID syndrome. The mechanisms by which the virus causes prolonged illness are still unclear. The aim of this review is to gather information regarding post-COVID syndrome so as to highlight its etiological basis and the nutritional regimes and supplements that can mitigate, alleviate or relieve the associated chronic fatigue, gastrointestinal disorders and continuing inflammatory reactions. Naturally-occurring food supplements, such as acetyl L-carnitine, hydroxytyrosol and vitamins B, C and D hold significant promise in the management of post-COVID syndrome. In this pilot observational study, we evaluated the effect of a food supplement containing hydroxytyrosol, acetyl L-carnitine and vitamins B, C and D in improving perceived fatigue in patients who recovered from COVID-19 but had post-COVID syndrome characterized by chronic fatigue. The results suggest that the food supplement could proceed to clinical trials of its efficacy in aiding the recovery of patients with long COVID.

Nifedipine is a calcium-antagonist whose principal action is reduction of peripheral resistance. The utilization of nifedipine is still limited in infancy. We have studied the immediate effect on hypertensive blood pressure values of nifedipine administered sublingually in 10 children (3 males and 7 females; aged 6-14 years) with different clinical diagnoses: acute glomerulonephritis (6 cases), lupus erythematosus systemicus (2 cases), membrane proliferative glomerulonephritis (1 case), pyelonephritis secondary to vesico-ureteral reflux (1 case). Nifedipine (0.25-0.50 mg/Kg) lowered systolic and diastolic blood pressure values from 167.5 +/- 19.8 mmHg and 103.5 +/- 18.4 mmHg to 126 +/- 19.8 mmHg and 81.5 +/- 15.1 mmHg, respectively, 30 minutes after administration (p less than 0.001). We propose nifedipine as a simple, effective and safe alternative drug for managing hypertensive emergencies in childhood.
