Is Tocilizumab An Effective Therapy For Severe Covid-19: A Single Center Study.

Background: The quest for effective therapies in Covid-19 continues. We compared the outcome of severe COVID-19 patients treated with and without Tocilizumab, an IL-6 inhibitor. Methods: This is a prospective cohort study on the clinical characteristics and outcomes of patients with Covid-19 patients admitted at The Indus Hospital and Health Network, Karachi between 24th March and 19th June 2020. Adult patients who received TCZ were compared with respect to mortality and days of hospitalization with those who did not. Results: A total of 88 patients including 41 patients in the TCZ group and 47 in non-TCZ group were recruited. Baseline demographic characteristics were comparable. TCZ group patients presented with worse clinical features including median SpO2 82% vs 88%, p<0.05 and CRP 193 vs 133.9 mg/L, p<0.05. Approximately, 85.4% were admitted in ICU compared to 69.8% in non-TCZ group, p>0.05. Mortality was not different among the groups (46% in TCZ group vs 51.1% in non-TCZ group, p>0.05). Median length of hospital stays, days of intubation, use of inotropic agents, and use of invasive ventilation or in-hospital complications were similar between the groups. Sub-group analysis revealed that mortality within TCZ group was associated with high IL-6 levels (173 vs 69.66 pg/ml, p<0.05), ICU admission (100% vs 72%, p<0.05), need for mechanical ventilation (100% vs 13.6%, p<0.05) and higher incidence of in-hospital complications, p<0.05. Conclusion: TCZ failed to demonstrate any mortality benefit in our patients. Non-survivors within the TCZ group were more critical compared to survivors and developed more in hospital complications.

Experiences of medical and dental students of Pakistan during COVID-19 pandemic lockdown: a qualitative study.

OBJECTIVE: The COVID-19 pandemic resulted in medical institutes being shut down. Face-to-face activities were shifted to online medium. The unpredictability of the situation impacted medical faculty and students alike, creating panic and anxiety. Since these students are to take hold of the healthcare system of the country soon, it is important to learn their perspective on how COVID impacted them. Therefore, this study aimed to explore the lived experiences of Pakistani medical students in-depth by a qualitative observation of their personal and educational experiences. DESIGN: A phenomenological qualitative study interviewing medical students of Pakistan was conducted. PARTICIPANTS/METHODOLOGY: This study was designed to interview medical and dental students from various cities in Pakistan using a semistructured, open-ended questionnaire. A total of 34 interviews were recorded and transcripts were prepared. All authors (SI, SS, IA and MS) were involved in the thematic analysis of the data, whereby transcripts were read thoroughly, and codes were developed. Similar codes were then combined to generate themes. RESULTS: Three major themes emerged after the analysis of results. The students' 'diverse experiences' of panic and anxiety or excitement were high initially but gradually reduced as time progressed. The 'unprecedented academic experiences' of students included teaching/learning, communication and technical challenges that they faced during online classes. Despite facing a lot of challenges, the students still saw 'light at the end of the tunnel' and looked forward to going back to their college. CONCLUSION: The effects of COVID on the physical, psychological, social and academic life of medical students were enormous. It is highly recommended that institutes and faculty provide support for personal and professional development of students in these unprecedented times in the form of counselling, provision of technical facilities or leniency in fee process. Peer support is also considered crucial in reducing anxiety among students.

Inducting undergraduate medical students via WhatsApp-based multiple mini interviews during COVID-19 pandemic.

Selection of medical students requires both cognitive and soft skills assessment. Shalamar Medical and Dental College (SMDC) has been using on-campus multiple mini interviews to assess the latter but due to Covid-19 pandemic it became imperative that an alternative be found. The aim of this communication is to share the process SMDC went through to plan, design, and ultimately conduct WhatsApp-based multiple mini interviews (wMMI) in a low risk method as an entry criteria for undergraduate medical students. The process involved designing scenarios appropriate for online interviews, training the faculty members regarding conducting MMI as well as the use of technology, and designing an online webpage for enrolling, scheduling and assessing candidates. We were able to successfully complete wMMI process for 522 candidates within one week in a low risk setting using WhatsApp as communication medium with strong IT and administrative support.

Sensitivity and Specificity of Anti-SARS-CoV-2 Detection Kits - Comparison and Agreement between Fifteen Different Assays.

Accurate and rapid diagnosis of coronavirus disease 2019 (COVID-19) is critical for proper care and identification of affected individuals. This led to early availability of many serological assays in the market, but with limited validation. In this study, we aimed to validate the serological assays based on different techniques. We evaluated 15 different assays based on four immunoassay techniques in 235 patients. The most sensitive kits employed were as follows: immunochromatography (Zybio severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] IgM/IgG Antibody Assay Kit - 83%), ELISA (Aeskulisa SARS-CoV-2 NP IgG -88.1%), chemiluminescence (Alinity SARS-CoV-2 IgG - 82.2%), and immunofluorescence (Lifotronic FA160 (Shenzhen SARS-CoV-2 Assay Kit [IgG]) - 88.9%). The kits by Uniper (Singuway Biotec COVID-19 IgM/IgG Presumptive Kit), Genrui 2019-nCoV IgM/IgG Test Kit, Wondfu SARS-CoV-2 Antibody Test, and Aeskulisa SARS-CoV-2 NP IgG exhibited 100% specificity, whereas IgG assay using Lifotronic FA160 (Shenzhen SARS-CoV-2 Assay Kit) exhibited the lowest specificity at 58%. Maximum agreement was observed between Aeskulisa SARS-CoV-2 NP IgG and Alinity SARS-CoV-2 IgG at 94%. Serological tests are practical alternatives, but their reliability depends on critical validation. The COVID-19 pandemic warranted investment in healthcare research at both the national and international levels.
