BACKGROUND Zinc supplementation has been considered one of the potential therapies for coronavirus disease-19 (COVID-19). We aimed to examine zinc efficacy in adult patients with COVID-19 infection. METHODS We conducted a prospective, randomized, double-blind, placebo-controlled, multicenter trial. Patients tested positive for COVID-19 without end organ failure were randomized to oral zinc (n = 231) or matching placebo (n = 239) for 15 days. The primary combined outcome was death due to COVID-19 or ICU admission within 30 days after randomization. Secondary outcomes included length of hospital stay for inpatients and duration of COVID-19 symptoms with COVID-19 related hospitalization for outpatients. FINDINGS One hundred ninety patients (40.4%) were ambulatory and 280 patients (59.6%) were hospitalized. Mortality at 30-day was 6.5% in Zinc group and 9.2% in Placebo group [odds ratio (OR) 0.70 (0.37-1.32)]; ICU admission rate was respectively 5.2% and 11.3% [OR 0.46 (0.23-0.88)]. Combined outcome was lower in zinc group compared to placebo group [OR 0.62 (0.38-0.99)]. Consistent results were observed in prespecified subgroups of patients with age < 65 years, those with comorbidity, and those who needed oxygen therapy at baseline. Length of hospital stay was shorter in zinc group compared to placebo group [difference 3.5 days, 95% CI (2.76-4.23)] in inpatients group; duration of COVID-19 symptoms decreased with zinc treatment compared to placebo in outpatients [difference 1.9 days, 95% CI (0.62-2.6)]. No severe adverse events were observed during the study. INTERPRETATION Our results showed that in COVID-19 patients, oral zinc can decrease 30-day death and ICU admission rate and can shorten symptoms duration.
ObjectiveThe objective of this study was to compare the analgesic effect and tolerance profile of acupuncture versus intravenous (IV) titrated morphine in patients presenting to the emergency department (ED) with renal colic.Materials and methodsA total of 115 patients were randomized into two groups. Patients in the IV titrated-morphine group (n=61) received 0.1 mg/kg morphine every 5 minutes until pain score dropped by at least 50% of its baseline value. Patients in the acupuncture group (n=54) received an acupuncture session of 30 minutes following a prespecified protocol. The visual analog scale (VAS) was used to assess pain intensity at baseline and at 10, 20, 30, 45, and 60 minutes following the start of the treatment protocol. Possible treatment side effects were also recorded.ResultsNo significant differences were found between the two groups concerning age, sex, or baseline VAS score. From the 10th minute until the end of the intervention, acupuncture was associated with a deeper analgesic effect than titrated morphine (P<0.05 from the 10th minute and over). Analgesia was also faster in the acupuncture group, with time to obtain 50% reduction of baseline VAS of 14 minutes in the acupuncture group versus 28 minutes in the IV titrated-morphine group (P<0.001). Only three patients in the acupuncture group experienced minor side effects versus 42 in the morphine group (P<0.001). No major side effects were observed in this study.ConclusionIn ED patients with renal colic, acupuncture was associated with a much faster and deeper analgesic effect and a better tolerance profile in comparison with titrated IV morphine.
