Role of Co-trimoxazole in Severe COVID-19 Patients
Coronavirus Disease 19 (COVID-19) is a global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Severe disease occurs in 15% of the cases with COVID-19 and may progress to critical disease in only 5% of the cases with a high risk of mortality. Critical disease may present as acute respiratory failure secondary to Acute Respiratory Distress Syndrome (ARDS) and is caused by the body's hyper-immune response to the virus in the form of a cytokine storm syndrome (CSS). There is currently no effective anti-viral treatment against SARS-CoV-2 and the mainstay of treatment is supportive. Co-trimoxazole (combination of trimethoprim and sulphamethoxazole in a 1:5) ratio is a Sulphur containing anti-folate bactericidal antibiotic indicated for the treatment of respiratory tract infections. It has been around for over 60 years and is inexpensive and readily available with a good safety profile. It has a rapid onset of action with excellent bioavailability and lung penetration. In addition to having antimicrobial properties co-trimoxazole have immunomodulatory and anti-inflammatory properties and may be a potential treatment option for cytokine storm syndrome mediated severe COVID-19.
This open-label randomized controlled trial will be conducted in the department of medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Anwar Khan Modern Medical college and Mughda Medical College Hospital (DMCH), Dhaka for a duration of 6 months following approval of this protocol. It will recruit at least 94 consecutive adults (18 years or older) patients with clinically suspected COVID-19 and severe illness as per WHO criteria. After taking informed written consent patients will be randomly assigned in a 1:1 ratio to either oral co-trimoxazole in addition to standard therapy or standard therapy alone. Baseline characteristics, changes in the physiological and biochemical parameters like (SpO2/FiO2 ratio, respiratory rate, body temperature and C - reactive protein), length of hospital stay, side effects of drugs, requirement for ventilatory support (non-invasive and invasive ventilation) and in-patient mortality between the two groups will be compared.
Conclusion If the results from this clinical trial demonstrate the beneficial effects of co-trimoxazole in severe COVID-19 patients it could be used widely, thereby reducing the need for respiratory support and potentially saving thousands of lives in developing nations with limited resources where healthcare may be easily overwhelmed.

Detailed Description
Coronavirus disease (COVID-19) caused by SARS-COV2, represents a highly transmissible and potentially fatal disease that is of great global public health concern at this moment. The pandemic situation in Bangladesh is also evolving rapidly with positive cases and deaths increasing each day. Epidemiological changes in COVID-19 infection should be monitored taking into account potential routes of transmission and subclinical infections, in addition to the adaptation, evolution, and virus spread among humans and possible intermediate animals and reservoirs. But till today there is no specific management to deal with this highly deadly viral infection. Howeverthere are few drugs which might cause some beneficial effects in the recovery of the patient. Cotrimoxazole is a time tested antibiotic which has been in clinical use for 60 years with anti-bacterial action against a wide range of organism. In addition to the antimicrobial effects, co-trimoxazole has anti-inflammatory and immunomodulatory effects. Co-trimoxazole has previously been shown to exert anti-cytokine effect by inhibiting interleukin 1, 6 (IL-1, IL-6) and Tumour Necrosis Factor α (TNF α) which are the major cytokines identified in patients with severe COVID-19. As in some case reports this has shown significant clinical improvement in ARDS, so there is a possibility, that cotrimoxazole might have also role in improving the clinical outcome in COVID-19 patients especially in moderate to severe cases. As till today there is no specific treatment for COVID-19 infections, if cotrimoxazole ifs found to be effective this will bring a great benefit to the target populations. Beside this, cotrimoxazole is a very cheap drug in comparison to other ones this will also be of great economical benefit in taking cares of the general population. As there is no such study published about the role of cotrimoxazole in COVID-19 patients, this study will generate a new information which bring a great benefit in battling with the COVID-19 infection.
Research Question:
What is the outcome of co-trimoxazole in severe COVID-19 patients?
Objectives:
General Objectives To assess the clinical outcome of co-trimoxazolein patients with severe COVID-19
Specific Objectives:
To assess length of stay who are treated with co-trimoxazole in addition to standard treatment versus standard treatment alone.
To find out side effects (rash.itching. dizziness, headache, nausea,vomiting, diarrhea, sore throat, unusual bruising or bleeding, yellowing of the skin or eye discolorations, joint or muscle pain,red or purple skin.etc) of drugs who are treated with co-trimoxazole in addition to standard treatment versus standard treatment alone.
To find out requirement for ventilator support (non-invasive and invasive ventilation) who are treated with co-trimoxazole in addition to standard treatment versus standard treatment alone.
To assess the mortality in patients with severe COVID-19 who are treated with co-trimoxazole in addition to standard treatment versus standard treatment alone.
