Efficacy and Safety of Ivermectin for Treatment and Prophylaxis of COVID-19 Pandemic
Condition: Covid19
MeSH terms: COVID-19
Study type: Interventional

Summary: 
      Background: Up-to-date, there is no recognized effective treatment or vaccine for the
      treatment of coronavirus disease (COVID-19) that emphasize urgency around distinctive
      effective therapies. This study aims to evaluate the anti-parasitic medication efficacy
      "Ivermectin" plus standard care (Azithromycin, Paracetamol, vitamin C, Zinc, Lactoferrin,
      Acetylcystein, prophylactic or therapeutic anticoagulation if D-dimer > 1000 and/or steroids)
      in the treatment of mild/moderate and severely ill cases with COVID 19 infection versus
      Hydroxychloroquine plus standard care, as well as Ivermectin prophylaxis of health care and/
      or household contacts.

      Subject and methods: 600 subjects; 400 symptomatic confirmed COVID-19 patients and 200 health
      care and household contacts distributed over 6 groups; Group I: 100 patients with
      Mild/Moderate COVID-19 infection received a 4-days course of Ivermectin plus standard care;
      Group II: 100 patients with mild/moderate COVID-19 infection received hydroxychlorquine plus
      standard care; Group III: 100 patients with severe COVID-19 infection received Ivermectin
      plus standard of care; Group IV: 100 patients with Severe COVID-19 infection received
      hydroxychlorquine plus standard care. Routine laboratory investigations and real time-
      polymerase chain reaction (rt-PCR) were reported before and after initiation of treatment.
      Group V stick to personal protective equipment (PPE) plus Ivermectin, and Group VI stick to
      PPE only and both groups were followed for two weeks.

      (RCCT) study Study period: The study was carried out from 8th June to 15th September 2020.

      *Study population (Sampling Design and Sample Size):

      The study was conducted on 600 subjects; 400 patients and 200 health care and household

           Ivermectin 400 mcg/kg body weight maximum 4 tablets (6mg / tablet) once daily dose
           before breakfast plus standard care as issued by Egyptian protocol of COVID-19 treatment
           (Azithromycin 500mg once daily/5days, Paracetamol 500mg as needed, vitamin C 1gm once
           daily, Zinc 50 mg once daily, Lactoferrin 100mg sachets/12 hours & Acetylcystein
           200mg/8hours & prophylactic or therapeutic anticoagulation if D-dimer > 1000), (MOH
           version 30 May 2020).

        -  Group II: 100 patients with mild/moderate COVID-19 infection received hydroxychlorquine
           (400 every 12 hours for one day followed by 200 mg every 12 hours for 5 days) plus
           standard care (Azithromycin 500mg once daily/5days, Paracetamol 500mg as needed, vitamin
           C 1gm once daily, Zinc 50 mg once daily, Lactoferrin 100mg sachets /12 hours &
           Acetylcystein 200mg sachets /8 hours & prophylactic or therapeutic anticoagulation if
           D-dimer > 1000) as issued by Egyptian protocol of COVID-19 treatment.

        -  Group III: 100 patients with severe COVID-19 infection received a 4 days course of
           Ivermectin 400 mcg/kg body weight maximum 4 tablets (6mg / tablet) once daily dose
           before breakfast plus standard care (Azithromycin 500mg once daily/5days, Paracetamol
           500mg as needed, vitamin C 1gm once daily, Zinc 50 mg once daily, Lactoferrin 100mg
           sachets/ 12 hours & Acetylcystein 200mg sachets/ 8 hours & prophylactic or therapeutic
           anticoagulation if D-dimer > 1000) as issued by Egyptian protocol of COVID-19 treatment
           for severe patients.

        -  Group IV: 100 patients with Severe COVID-19 infection received hydroxychlorquine (400 mg
           every 12 hours for one day followed by 200 mg every 12 hours for 9 days) plus standard
           care (Azithromycin 500mg once daily/5days, Paracetamol 500mg as needed, vitamin C 1gm
           once daily, Zinc 50 mg once daily, Lactoferrin 100mg/12 hours & Acetylcystein 200mg
           sachets/ 8 hours & prophylactic or therapeutic anticoagulation if D-dimer > 1000) as
           issued by Egyptian protocol of COVID-19 treatment for severe ill patients.

        -  Group V: 100 health care and or household patients' contacts received a prophylactic
           dose of ivermectin 400 micrograms/kg single oral dose before breakfast to be repeated
           after one week in addition to PPE (personal protective equipment).

        -  Group VI: 100 health care and or household patients' contacts received only PPE

      Study methods and Tools:

      All patients were subjected to:

        -  Full history and clinical examination taking, and laboratory assessment including liver
           function tests, kidney function tests, full blood count, serum Ferritin level.
           C-reactive protein (CRP), D-dimer, rt- PCR for COVID-19 and, radiological assessments
           including CT chest.

        -  Follow up: Patients were followed up daily clinically and by laboratory assessment for
           two weeks but radiological assessment after two weeks or until one of the endpoints is
           reached. Follow up the duration of treatment, swab conversion, hospital stay, the
           clinical and radiological improvement was recorded.
