A two-arm, randomized, controlled, multi-centric, open-label Phase-2 study to evaluate the efficacy and safety of Itolizumab in moderate to severe ARDS patients due to COVID-19

An uncontrolled increase in cytokine production may lead to systemic hyperinflammation, vascular hypo-responsiveness, increased endothelial permeability, hypercoagulation, multi-organ dysfunction and eventually death in moderate to severely ill COVID-19 patients. Targeting T-cells, an important driver of the hyperinflammatory response, in the treatment of COVID-19, could potentially reduce mortality and improve survival rates. Itolizumab is an anti-CD6 humanized monoclonal antibody with an immunomodulating action on Teffector cells that downregulates T-cell activation, proliferation and subsequent production of various chemokines and cytokines. The efficacy and safety of Itolizumab for the treatment of cytokine release syndrome in patients with moderate to severe acute respiratory distress syndrome (ARDS) due to COVID-19 was evaluated in a multi-centric, open-label, two-arm, controlled, randomized, phase 2 study. Eligible patients were randomized (2:1) to arm A (best supportive care + Itolizumab) and arm B (best supportive care). The primary outcome of interest was reduction in all-cause mortality 30 days after enrolment. Thirty-six patients were screened, 5 were treated as first dose sentinels and the rest were randomized, whilst 4 patients were considered screen failures. Two patients in the Itolizumab treatment arm discontinued prior to receiving the first dose and were replaced. At the end of 1 month, there were 3 deaths in arm B, and none in arm A (p= 0.0296). At the end of the follow-up period, more patients in Arm A had improved SpO2 without increasing FiO2 (p=0.0296), improved PaO2 (p=0.0296), and reduction in IL-6 (43 pg/ml vs 212 pg/ml; p=0.0296) and tumor necrotic factor- (9 pg/ml vs 39 pg/ml; p=0.0253) levels. Itolizumab was generally safe and well tolerated, and transient lymphopenia (11 patients in Arm A) and infusion reactions (7 patients) were the commonly reported treatment related safety events. These encouraging results indicate that larger clinical trials are warranted to establish the role of Itolizumab in controlling immune hyperactivation in COVID-19.

Therapeutic Role of Yoga in Type 2 Diabetes

Yoga originated in India more than 5,000 years ago and is a means of balancing and harmonizing the body, mind, and emotions. Yoga practice is useful in the management of various lifestyle diseases, including type 2 diabetes. Psycho-neuro-endocrine and immune mechanisms are involved in the beneficial effects of yoga on diabetes. Incorporation of yoga practice in daily life helps to attain glycaemic control and reduces the risk of complications in people with diabetes. In this review, we briefly describe the role of various yoga practices in the management of diabetes based on evidence from various clinical studies.

Pneumococcal Vaccine in Diabetes: Relevance in India.

Currently we have more than 65 million Diabetes patients in India with estimated 80 million prediabetics. Diabetes is a immunologically vulnerable population to develop all types of microbial infections. Pneumoccocal infections do have a substantial morbidity and mortality burden in the community. India has a large geriatric pool now which has substantially increased pneumococcal disease burden. Diabetes is a well-known risk factor for pneumococcal infection and predisposes individuals to nasopharyngeal colonization with the pneumococcus which is associated with invasive infection. In diabetics who are elderly, with chronic kidney or pulmonary disease and long standing duration of the disease with poor glycemic control are the highest risk group susceptible to invasive pneumococcal disease. With now availibilty of Pneumoccal vaccine in India, now it may be an preventive option which can be offered. Most global organisations recommend pneumococcal vaccination to diabetics.
