Usefulness of convalescent plasma transfusion for the treatment of severely ill COVID-19 patients in Pakistan.

BACKGROUND: Convalescent plasma(CP) was utilized as potential therapy during COVID-19 pandemic in Pakistan. The study aimed at appraisal of CP transfusion safety and usefulness in COVID pneumonia. METHODS: Single arm, MEURI study design of non-randomized open label trial was conducted in five centers. Patients werecategorized as moderately severe, severe, and critical. The primary endpoint was a) improvement in clinical status and change in category of disease severity; secondary endpoint was b) CP ability to halt disease progression to invasive ventilation. CP transfused to hospitalized patients. Statistical tests including median (interquartile ranges), Mann-Whitney U test, Fisher's exact test using SPSS ver. 23, ANOVA and Chi-square test were applied for the analysis of results parameters before and after CP treatment. SOFA score was applied for multiorgan failure in severe and critical cases. RESULTS: A total of 50 adult patients; median age 58.5 years (range: 29-92 years) received CP with infusion titers; median 1:320 U/mL (Interquartile range 1:80-1:320) between April 4 to May 5, 2020. The median time from onset of symptoms to enrollment in trial was 3 to 7 days with shortness of breath and lung infiltration as severity criterion. In 35 (70%) recipients, oxygen saturation improved from 80 to 95% within 72h, with resolution of lung infiltrates. Primary endpoint was achieved in 44 (88%) recipients whereas secondary endpoint was achieved in 42 (84%). No patient experienced severe adverse events. A high SOFA score (> 7) correlated with deaths in severe and critical patients. Eight (16%) patients expired due to comorbidities; cardiac arrest in 2 (4%), multiorgan failure secondary to cytokine storm in 5 (10%) and ventilator associated complications in 1 (2%). CONCLUSION: CP transfusion can be used as a safe and useful treatment in moderately severe and severe patients. TRIAL REGISTRATION: The trial registration number is NCT04352751  ( https://www.irct.ir/search/result?query=IRCT20200414047072N1 ). Trial Registration date is 28th April 2020.

"Asocial" Virus in the Social World: A Comparative Study of the Internet Usage and Psychological States before and during COVID-19 Pandemic

The study aims to find out the changes in internet usage mainly screen time and online activities, health information seeking behavior and various psychological states during COVID-19. The sample consists of300 participants. The age range is 15-62 year, mean age is 27.41. The study was conducted during the nationwide lockdown in India. The data was analyzed with t-test and percentage difference analysis. The present study suggests that there has been an increase of screen time which indicates towards sedentary lifestyle. Preference to use internet to carry day to day work has increased including its use for variety of purposes. Increase in anxiety and depression during the pandemic was found. The findings suggest that there is a need for educating people about maintaining healthy lifestyle and avoiding sedentary behavior. There is also need for psycho educating people and provide them with mental health services.

COVID-19 Infection-Related Coagulopathy and Acute Limb Ischemia in a Patient With Pre-existing Diabetes.

The pandemic of coronavirus 19 (COVID-19) infection has presented the clinicians with a challenge never experienced on this scale before. Although coagulopathy has been well described in association with COVID-19 infection, some recommendations have emerged so far for the potential role of empiric anticoagulation in specific situations. We describe a case of a middle-aged male with extensive acute lower limb ischemia and severe pneumonia related to COVID-19 infection. This case highlights the role of prophylactic anticoagulation in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection regardless of co-morbidities and D- dimer levels.

Clinical Variants, Characteristics, and Outcomes Among COVID-19 Patients: A Case Series Analysis at a Tertiary Care Hospital in Karachi, Pakistan.

Introduction Coronavirus disease 2019 (COVID-19) has become a global threat to public health. The current study investigates alterations in the biological estimates concerning the severity, recovery, mortality, and assessment of treatment-based outcomes. Methods A case series of 165 COVID-19 patients admitted to OMI Institute (a tertiary care hospital) was conducted between May and August 2020. The data regarding demographic characteristics, comorbid conditions, radiographic abnormalities, biological estimations, symptoms, treatment, disease progression, complications, and outcomes were recorded using a structured questionnaire. Laboratory estimations included complete blood count (CBC), renal and electrolyte profile, liver function tests (LFTs), hematological indices, and inflammatory markers. Chest X-ray, electrocardiogram (ECG), and a high-resolution computed tomography (HRCT) scan were also performed, and data were extracted from the medical records. Analysis was done using the Statistical Package for the Social Sciences (SPSS) version 22.0. Results Out of the 165 COVID-19 patients, 79.4% recovered and were successfully discharged, while 20.6% of inpatient died. The patients' mean age was 56.03 ± 15.96 years, with a male majority (55.1%). The most common comorbid conditions were diabetes and hypertension; fever and dry cough were among the most frequently reported symptoms. The chest imaging findings among the severe/critical COVID-19 patients showed extensive bilateral patchy opacities. The median laboratory investigations, including neutrophil-to-lymphocyte ratio (NLR) (14.83), C-reactive protein (CRP) (7.4 mg/dl), lactate dehydrogenase (LDH) (786 IU/L), ferritin (1401.15 mcg/ml), and mean oxygen saturation (88.25%), were significantly altered among cases with increased disease severity and those who expired (p<0.05). The proportion of acute respiratory distress syndrome (ARDS) and sepsis development was significantly high among severe/critical COVID-19 patients (p<0.05). Treatment with tocilizumab, remdesivir, doxycycline, ivermectin, enoxaparin sodium, and steroids was deemed to be potentially effective treatment options in terms of reducing COVID-19 severity and chances of recovery. Furthermore, age (OR 1.05; p=0.047), presence of comorbidity (OR 8.471; p=0.004), high NLR, LDH (final outcome) (OR 1.361 and 1.018; p<0.05), and CRP levels (midpoint) (OR 1.631; p=0.05) were identified as the strong predictors of death among COVID-19 patients. Conclusion The study identified several alterations in the clinical profile of the COVID-19 patients concerning severity during the hospital stay, affecting prognosis. Clinically, tocilizumab, remdesivir, doxycycline, ivermectin, enoxaparin sodium, and steroids were identified as potential therapeutic options for COVID-19 due to their ability to alter disease-associated severity and recovery rate.
