    Background: Acute Respiratory Distress Syndrome (ARDS) is caused by non-cardiogenic pulmonary edema and occurs in critically ill patients. It is one of the fatal complications observed among severe COVID-19 cases managed in intensive care units (ICU). Supportive lung-protective ventilation and prone positioning remain the mainstay interventions. Purpose: We describe the severity of ARDS, clinical outcomes, and management of ICU patients with laboratory-confirmed COVID-19 infection in multiple Saudi hospitals. Methods: A multicenter retrospective cohort study was conducted of critically ill patients who were admitted to the ICU with COVID-19 and developed ARDS. Results: During our study, 1154 patients experienced ARDS: 591 (51.2%) with severe, 415 (36.0%) with moderate, and 148 (12.8%) with mild ARDS. The mean sequential organ failure assessment (SOFA) score was significantly higher in severe ARDS with COVID-19 (6 ± 5, p = 0.006). Kaplan–Meier survival analysis showed COVID-19 patients with mild ARDS had a significantly higher survival rate compared to COVID-19 patients who experienced severe ARDS (p = 0.023). Conclusion: ARDS is a challenging condition complicating COVID-19 infection. It carries significant morbidity and results in elevated mortality. ARDS requires protective mechanical ventilation and other critical care supportive measures. The severity of ARDS is associated significantly with the rate of death among the patients.

    Global emerging Omicron variant of SARS-CoV-2: Impacts, challenges and strategies
    (Elsevier, 2023) Dhama, Kuldeep; Nainu, Firzan; Frediansyah, Andri; Yatoo, Mohd Iqbal; Mohapatra, Ranjan K.; Chakraborty, Sandip; Zhou, Hao; Islam, Md Rabiul; Mamada, Sukamto S.; Kusuma, Hendrix Indra; Rabaan, Ali A.; Alhumaid, Saad; Al Mutair, Abbas; Iqhrammullah, Muhammad; Al-Tawfiq, Jaffar A.; Al Mohaini, Mohammed; Alsalman, Abdulkhaliq J.; Tuli, Hardeep Singh; Chakraborty, Chiranjib; Harapan, Harapan; Medicine, School of Medicine
    Newly emerging variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are continuously posing high global public health concerns and panic resulting in waves of coronavirus disease 2019 (COVID-19) pandemic. Depending on the extent of genomic variations, mutations and adaptation, few of the variants gain the ability to spread quickly across many countries, acquire higher virulency and ability to cause severe disease, morbidity and mortality. These variants have been implicated in lessening the efficacy of the current COVID-19 vaccines and immunotherapies resulting in break-through viral infections in vaccinated individuals and recovered patients. Altogether, these could hinder the protective herd immunity to be achieved through the ongoing progressive COVID-19 vaccination. Currently, the only variant of interest of SARS-CoV-2 is Omicron that was first identified in South Africa. In this review, we present the overview on the emerging SARS-CoV-2 variants with a special focus on the Omicron variant, its lineages and hybrid variants. We discuss the hypotheses of the origin, genetic change and underlying molecular mechanism behind higher transmissibility and immune escape of Omicron variant. Major concerns related to Omicron including the efficacy of the current available immunotherapeutics and vaccines, transmissibility, disease severity, and mortality are discussed. In the last part, challenges and strategies to counter Omicron variant, its lineages and hybrid variants amid the ongoing COVID-19 pandemic are presented.
