Cytokine release syndrome (CRS) or cytokine storm is thought to be the cause of inflammatory lung damage, worsening pneumonia and death in patients with COVID-19. Steroids (Methylprednislone or Dexamethasone) and Tocilizumab (TCZ), an interleukin-6 receptor antagonist, are approved for treatment of CRS in India. The aim of this study was to evaluate the efficacy and safety of combination therapy of TCZ and steroid in COVID-19 associated CRS.This retrospective cohort study was conducted at Noble hospital and Research Centre (NHRC), Pune, India between April 2 and November 2, 2020. All patients administered TCZ and steroids during this period were included. The primary endpoint was incidence of all cause mortality. Secondary outcomes studied were need for mechanical ventilation and incidence of systemic and infectious complications. Baseline and time dependent risk factors significantly associated with death were identified by Relative risk estimation.Out of 2831 admitted patients, 515 (24.3% females) were administered TCZ and steroids. There were 135 deaths (26.2%), while 380 patients (73.8%) had clinical improvement. Mechanical ventilation was required in 242 (47%) patients. Of these, 44.2% (107/242) recovered and were weaned off the ventilator. Thirty seven percent patients were managed in wards and did not need intensive care unit (ICU) admission. Infectious complications like hospital acquired pneumonia, blood stream bacterial and fungal infections were observed in 2.13%, 2.13% and 0.06% patients respectively. Age ≥ 60 years (P = .014), presence of co-morbidities like hypertension (P = .011), IL-6 ≥ 100 pg/ml (P = .002), D-dimer ≥ 1000 ng/ml (P < .0001), CT severity index ≥ 18 (P < .0001) and systemic complications like lung fibrosis (P = .019), cardiac arrhythmia (P < .0001), hypotension (P < .0001) and encephalopathy (P < .0001) were associated with increased risk of death.Combination therapy of TCZ and steroids is likely to be safe and effective in management of COVID-19 associated cytokine release syndrome. Efficacy of this anti-inflammatory combination therapy needs to be validated in randomized controlled trials.

Background: Cytokine release syndrome (CRS) or cytokine storm is thought to be the cause of inflammatory lung damage, worsening pneumonia and death in patients with COVID-19. Steroids (Methylprednisolone or Dexamethasone) and Tocilizumab (TCZ), an interleukin-6 receptor antagonist, are approved for the treatment of CRS in India. The aim of this study was to evaluate the efficacy and safety of combination therapy of TCZ and steroids in COVID-19 associated CRS. Methods: This retrospective cohort study was conducted at a tertiary level private hospital in Pune, India between 2nd April and 2nd November 2020. All patients administered TCZ and steroids for treatment of CRS were included. The primary endpoint was the incidence of all-cause mortality. Secondary outcomes studied were the need for mechanical ventilation and incidence of infectious complications. Baseline and time-dependent risk factors significantly associated with death were identified by Relative risk estimation. Results: Out of 2831 admitted patients, 515 (24.3% females) were administered TCZ and steroids. Median age of the cohort was 57 (IQR: 46.5, 66) years. Almost 72 % patients had preexisting co-morbidities. Median time to TCZ administration since onset of symptoms was 9 days (IQR: 7, 11). 63% patients needed intensive care unit (ICU) admission. Mechanical ventilation was required in 242 (47%) patients. Of these, 44.2% (107/242) recovered and were weaned off the ventilator. There were 135 deaths (26.2%), while 380 patients (73.8%) had clinical improvement. Infectious complications like hospital acquired pneumonia, bloodstream bacterial and fungal infections were observed in 2.13 %, 2.13 % and 0.06 % patients respectively. Age ≥ 60 years (p=0.014), presence of co-morbidities like hypertension (p = 0.011), IL-6 ≥ 100 pg/ml (p = 0.002), D-dimer ≥ 1000 ng/ml (p < 0.0001), CT severity index ≥ 18 (p < 0.0001) and systemic complications like lung fibrosis (p = 0.019), cardiac arrhythmia (p < 0.0001), hypotension (p < 0.0001) and encephalopathy (p < 0.0001) were associated with increased risk of death. Conclusions: Combination therapy of TCZ and Steroids is likely to be safe and effective in the management of COVID-19 associated cytokine release syndrome. Efficacy of this anti-inflammatory combination therapy needs to be validated in randomized controlled clinical trials.

Background: The second COVID-19 wave in India, triggered by the Delta variant,has been associated with an unprecedented increase in cases of COVID-19 associated Mucormycosis(CAM), mainly Rhino-orbito-cerebral mucormycosis(ROCM).The primary reason appears to be an unusual alignment of multiple risk factors in patients like prevalence of hypoxia, uncontrolled diabetes mellitus, indiscriminate use of steroids, high iron levels and immune dysfunction. Methods: This retrospective cohort study was conducted at Noble hospital and Research Centre (NHRC), Pune, Western India between 1st April 2020 and 1st August 2021 to identify patients admitted with CAM. The primary endpoint was incidence of all cause mortality due to CAM. Secondary outcomes studied were need for mechanical ventilation and intensive care unit(ICU) admission. Baseline and time dependent risk factors significantly associated with death due to CAM were identified by Relative risk estimation. Results: 59 patients were diagnosed with Mucormycosis at NHRC (58 ROCM, 1 Renal (disseminated) mucormycosis). Median age of the cohort was 52(IQR: 41,61) years and it included 20.3% females. Median duration from first positive COVID-19 RT PCR test to diagnosis of Mucormycosis was 17(IQR: 12,22) days. 90% patients were diabetic with 30% being newly diagnosed at the time of COVID-19 admission and 89% having uncontrolled sugar level (HbA1c > 7%). All patients were prescribed steroids during treatment for COVID-19. 56% patients were prescribed steroids for non-hypoxemic, mild COVID (irrational steroid therapy) while in 9%, steroids were indicated but were prescribed in inappropriately high dose. Majority of the patients were treated with a combination of surgical debridement(94%), intravenous Amphotericin B(91%) and concomitant oral Posoconazole therapy(95.4%). 74.6% patients were discharged after clinical and radiologic recovery while 25.4% (15 patients) died. On Relative risk analysis, CT severity score during COVID-19 admission ≥18 (p=0.017), presence of orbital symptoms(p=0.002), presence of diabetic ketoacidosis(p=0.011) and cerebral involvement by Mucor(p=0.0004) were associated with increased risk of death. Duration of Amphotericin B therapy of ≥ 21 days was associated with statistically significant reduction in mortality(p=0.002). Conclusions: CAM is an uncommon, rapidly progressive, angioinvasive, opportunistic fungal infection which is fatal if left untreated. Combination of surgical debridement and antifungal therapy leads to clinical and radiologic improvement in majority of cases.

<p class="abstract">The role of biologicals in dermatology has seen an exponential growth in the last few years. Biologicals such as TNF-alpha inhibitors have now lost their novelty and are routinely used all over the world. As the pathogenesis of various diseases is now being understood better, we have been able to create more targeted biological therapies for a number of dermatological conditions. We attempt to compile an update on the newer biologicals in use today, and briefly touch upon the older ones as well. We conducted an extensive literature search and have covered TNF-alpha inhibitors, molecules against T cell receptors, Janus Kinase inhibitors, interleukin based molecules, fusion proteins, and some newer biologicals as well. Their mechanisms of action, indications and dosage have been covered in our review.</p>

Introduction: Peripheral arterial disease (PAD) decreases arterial perfusion leading to limb ischemia. It is considered one of the markers of subclinical atherosclerosis process. For this reason, it can be a major risk factor for ischemic stroke. Early detection of PAD has an important role in preventing ischemic stroke. Materials and Methods: This study was carried out in District Hospital, Barasat, Kolkata, from March 2011 to March 2013. Eighty-two patients with ischemic stroke (aged 40–80 years) were recruited. Patients having atrial fibrillation and diabetes mellitus and embolic source were excluded. Ankle–brachial index (ABI) was performed with ultrasonography Doppler in each patient. PAD was diagnosed when the ABI was below 0.9. The severity of stroke was assessed by the National Institutes of Health Stroke Scale. Statistical Analysis: For continuous variables, analysis of variance was used to compare three or more groups of patients and Student’s t-test for two groups. Chi-square test or Fisher’s exact test was used for categorical variables. For all analytical purposes, a two-tailed P < 0.05 was considered statistically significant. Results: According to ABI, 62 patients had no pad, 13 patients had mild, and 7 patients had severe PAD. High total cholesterol and low-density lipoprotein were significantly associated with low ABI (P = 0.001). High total cholesterol levels and low ABI were significantly correlated (P < 0.001). A significant association between moderately-low ABI and recurrent stroke was noted (P = 0.019). Conclusion: PAD is significantly associated with recurrent ischemic strokes. Evaluation of ABI for PAD revealed increased risk of recurrent stroke.
