Efficacy of Ivermectin Treatment on Disease Progression Among Adults With Mild to Moderate COVID-19 and Comorbidities: The I-TECH Randomized Clinical Trial.

Importance: Ivermectin, an inexpensive and widely available antiparasitic drug, is prescribed to treat COVID-19. Evidence-based data to recommend either for or against the use of ivermectin are needed. Objective: To determine the efficacy of ivermectin in preventing progression to severe disease among high-risk patients with COVID-19. Design, Setting, and Participants: The Ivermectin Treatment Efficacy in COVID-19 High-Risk Patients (I-TECH) study was an open-label randomized clinical trial conducted at 20 public hospitals and a COVID-19 quarantine center in Malaysia between May 31 and October 25, 2021. Within the first week of patients' symptom onset, the study enrolled patients 50 years and older with laboratory-confirmed COVID-19, comorbidities, and mild to moderate disease. Interventions: Patients were randomized in a 1:1 ratio to receive either oral ivermectin, 0.4 mg/kg body weight daily for 5 days, plus standard of care (n = 241) or standard of care alone (n = 249). The standard of care consisted of symptomatic therapy and monitoring for signs of early deterioration based on clinical findings, laboratory test results, and chest imaging. Main Outcomes and Measures: The primary outcome was the proportion of patients who progressed to severe disease, defined as the hypoxic stage requiring supplemental oxygen to maintain pulse oximetry oxygen saturation of 95% or higher. Secondary outcomes of the trial included the rates of mechanical ventilation, intensive care unit admission, 28-day in-hospital mortality, and adverse events. Results: Among 490 patients included in the primary analysis (mean [SD] age, 62.5 [8.7] years; 267 women [54.5%]), 52 of 241 patients (21.6%) in the ivermectin group and 43 of 249 patients (17.3%) in the control group progressed to severe disease (relative risk [RR], 1.25; 95% CI, 0.87-1.80; P = .25). For all prespecified secondary outcomes, there were no significant differences between groups. Mechanical ventilation occurred in 4 (1.7%) vs 10 (4.0%) (RR, 0.41; 95% CI, 0.13-1.30; P = .17), intensive care unit admission in 6 (2.4%) vs 8 (3.2%) (RR, 0.78; 95% CI, 0.27-2.20; P = .79), and 28-day in-hospital death in 3 (1.2%) vs 10 (4.0%) (RR, 0.31; 95% CI, 0.09-1.11; P = .09). The most common adverse event reported was diarrhea (14 [5.8%] in the ivermectin group and 4 [1.6%] in the control group). Conclusions and Relevance: In this randomized clinical trial of high-risk patients with mild to moderate COVID-19, ivermectin treatment during early illness did not prevent progression to severe disease. The study findings do not support the use of ivermectin for patients with COVID-19. Trial Registration: ClinicalTrials.gov Identifier: NCT04920942.

Therapeutic challenges of extrapulmonary dual organ system involvement in COVID-19: A case report.

Respiratory symptoms and signs remain the hallmark of coronavirus disease 2019 (COVID-19) infection. However, extrapulmonary manifestations of COVID-19 are not uncommon, and are likely to be underreported. The present study describes a clinical case of a 64-year-old patient with COVID-19 with marked extrapulmonary manifestations in the setting of strong positive reactions with cycle threshold values of reverse transcription polymerase chain reaction for COVID-19. He presented with asymptomatic bradycardia with wide pulse pressure, eventually requiring transvenous cardiac pacing. He later complained of lower abdominal pain associated with no bowel movements for four days. The computed tomography examination of the abdomen revealed circumferential wall thickening at the proximal ascending colon, suggestive of inflammatory changes and features of obstruction in the presence of inguinal hernia. Despite aggressive resuscitative efforts, the patient continued to deteriorate with multiorgan failure, and eventually succumbed to the disease after 6 days of hospitalization. The present case study deliberates the sharing of our clinical experience and therapeutic challenges in the management of COVID-19 with complex extrapulmonary manifestation.
