INTRODUCTION: Mortality rates and clinical characteristics of patients with coronavirus disease 2019 (COVID-19) admitted to the intensive care unit (ICU) vary significantly. OBJECTIVES: To describe the data of patients with pulmonary comorbidities who were admitted to the ICU with COVID-19 in Qatar in terms of demographic characteristics, coexisting conditions, imaging findings, and outcomes. METHODS: We conducted a retrospective study of the outcomes with regard to mortality and requirement of invasive ventilation, demographic characteristics, coexisting conditions, secondary infections, and imaging findings for critical care patients with COVID-19 in Qatar who had pulmonary comorbidities between March and June 2020. RESULTS: A total of 923 patients were included, 29 (3.14%) were found to have pulmonary disease. All these 29 patients' respiratory disease was noted to be asthma. Among these, three patients (10.3%) died in the ICU within 28 days of ICU admission. They were all above 50 years old. Nineteen (66%) patients required intubation and mechanical ventilation. Twenty-one (72.4%) patients were males. The most common comorbidities included diabetes mellitus (55.1%) and hypertension (62%). Eighteen (62%) patients developed secondary infections in the ICU. Five (17.24%) patients developed renal impairment. Twenty (69%) patients received tocilizumab as part of their COVID-19 management, and out of these 16 (80%) patients developed a coinfection. CONCLUSION: Patients with pulmonary disorders had higher mortality rates than other patients admitted to ICU during the same time frame with similar comorbidities; these patients require extra consideration and care to avoid disease progression and death.

INTRODUCTION: Pneumatocele formation in COVID-19 pneumonia is arguably a common occurrence. CASE PRESENTATION: We present a case of pneumatoceles, developing as a sequel of COVID-19 infection. We argue that pneumatocele formation in COVID-19 pneumonia is a common occurrence. Importantly pneumothorax, which can lead to a raised morbidity and mortality in these patients, can be a complication of a pneumatocele rupture. CONCLUSION: As pneumatocele in COVID-19 pneumonia patients can lead to life-threatening complications, we emphasize the need to formulate appropriate and standardized monitoring and management guidelines. Our literature review also discusses various plausible mechanisms leading to pneumatocele formation and points to management strategies that may prevent pneumatocele formation and its complications.

Our work highlights patients at risk of prolonged viral shedding in COVID-19 and its implications for isolation strategies and explores possible solution by PCR-CT value testing (cycle threshold value). We also review the impact of HIV on COVID-19.

BACKGROUND: Coronavirus disease 2019 (Covid-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It mainly affects the lungs and common symptoms are fever, cough and shortness of breath. Pneumothorax has been noted to complicate Covid-19 cases requiring hospital admission, however the exact incidence and risk factors are still unknown. DISCUSSION: We present a series of 3 cases of primary spontaneous pneumothorax with Covid-19 pneumonia. All cases in our series did not require positive pressure ventilation and none had any pre-existing lung disease. All were never smokers and had favourable outcomes despite having severe Covid-19 with a pneumothorax during the course of the disease. In our literature review we discuss several plausible mechanisms and risk factors resulting in a pneumothorax with Covid-19. CONCLUSION: Our cases are a reminder that an acute deterioration with hypoxia in a Covid-19 patient could indicate a pneumothorax. Pneumothorax is one of the reported complications in Covid-19 and clinician vigilance is required during assessment of patients, as both share the common symptom of breathlessness and therefore can mimic each other.
