TOCILIZUMAB - An Option for Patients With COVID-19 Associated Cytokine Release Syndrome; A Single Center Experience

Study Overview
=================
Brief Summary
-----------------
Investigators conducted this study to see the effectiveness of Tocilizumab in COVID-19 participants who were in cytokine release syndrome and there was also a control group who received steroids(RECOVERY TRIAL wasn't published or available at that time) this study was conducted in the early days of 1st wave of COVID in our country Pakistan so it was need of the day to develop some national guidelines on the basis of multiple studies' results from Pakistan.

Detailed Description
-----------------
Objectives: To analyze the effectiveness of Tocilizumab in moderate to severe Covid-19 participants on the basis of predefined assessment criteria. Study Settings: Single center, Fatima Memorial Hospital, Lahore. Study Design: Quasi experimental. Duration of Study: From 12th May, 2020 to 12th July, 2020. Participants & Methods: Sample size and technique: Sample size was 93; 33 participants were kept in experimental group, given Tocilizumab, 8mg/kg intravenously or 162 mg subcutaneously and rest of the 60 participants were given corticosteroids, methylprednisolone 80 mg/day. Consecutive sampling. Failure of therapy was labeled when participants were intubated or died, and the endpoints were failure-free survival which was the primary endpoint and overall survival secondary at the time of discharge.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Tocilizumab Group<br>Tocilizumab administration protocol: Patients received an initial dose calculated as per the body weight (8mg/kg) maximum 800mg/dose) over 1 hour, followed by up to three additional doses if required as per the response after the first dose with 8 hours intervals. Predefined Parameters of disease severity were assessed 12 to 24 hourly. Injection Paracetamol 1g was administered before infusion. | Drug: Tocilizumab<br>* Participants received an initial dose calculated as per the body weight (8mg/kg) maximum 800mg/dose) over 1 hour, followed by up to three additional doses if required as per the response after the first dose with 8 hours intervals. Predefined Parameters of disease severity were assessed 12 to 24 hourly. Injection Paracetamol 1g was administered before infusion. The response of the participants after Tocilizumab administration was recorded based on clinical parameters (Oxygen requirement, Fever, Need for invasive positive pressure ventilation), biochemical parameters (D-dimers, C-reactive protein (CRP), Ferritin, Lactate dehydrogenase (LDH) levels), Chest X-ray findings, and Repeated PCR test for COVID-19. Any side effects noted after administration of TOCILIZUMAB were recorded. Any side effects noted after administration of TCZ/ Corticosteroid were recorded.<br>* Other names: Experimental;|
| Active Comparator: Methylprednisolone (corticosteroid) group<br>Corticosteroid administration protocol: Patients received methylprednisolone 80mg/day in two divided doses as per national/local guidelines and predefined parameters of disease severity were assessed on each day. | Drug: Tocilizumab<br>* Participants received an initial dose calculated as per the body weight (8mg/kg) maximum 800mg/dose) over 1 hour, followed by up to three additional doses if required as per the response after the first dose with 8 hours intervals. Predefined Parameters of disease severity were assessed 12 to 24 hourly. Injection Paracetamol 1g was administered before infusion. The response of the participants after Tocilizumab administration was recorded based on clinical parameters (Oxygen requirement, Fever, Need for invasive positive pressure ventilation), biochemical parameters (D-dimers, C-reactive protein (CRP), Ferritin, Lactate dehydrogenase (LDH) levels), Chest X-ray findings, and Repeated PCR test for COVID-19. Any side effects noted after administration of TOCILIZUMAB were recorded. Any side effects noted after administration of TCZ/ Corticosteroid were recorded.<br>* Other names: Experimental;|
