ABSTRACT

Background: Prior to pulmonary function testing (PFT), local and international recommendations advise pre-procedural screening. Pulmonary function tests generate aerosol droplets containing millions of viruses, significantly increasing the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission not only to the individuals in and around the PFT office, but also to subsequent patients who undergo the test later in the same room. Methods: This clinical audit was carried out to establish the rate of positive pre-procedural SARS-CoV-2 PCR testing before a PFT. The data were obtained over a 6-week period from our ATS accredited pulmonary function laboratory at the Hamad General Hospital, Qatar (December 01, 2021, to January 10, 2022). The PFT laboratory was closed from January 10, 2022, till the date of this report (January 27, 2022) owing to an increase in COVID cases in the community in Qatar during the fourth wave. Results: All the patients scheduled for PFT were asymptomatic of COVID-19. A total of 331 individuals were scheduled for PFT, and 221 PFTs were performed. There were 109 no-shows for both the PCR and the PFT. Between weeks 1 and 4, all the pre-procedural SARS-CoV-2 PCR tests were negative. The weekly average number of COVID-19 cases in Qatar increased from 157 per 100,000 population in week 1 to 2,918 in week 6.2 There was a similar trend in the pre-procedural SARS-CoV-2 PCR tests that increased and resulted in identifying 9 cases with positive SARS-CoV-2 PCR test over weeks 5 and 6 (). Conclusion: As the number of documented positive SARS-CoV-2 PCR tests in the community grew, so did the pre-procedural COVID-19 PCR positivity and the number of no-shows. The large number of no-shows may indicate greater worry or concern about contracting COVID-19 when visiting the hospital amid peak community cases. Our findings further call into question the utility of routinely performing pre-procedural PCR screening in asymptomatic cases when the prevalence of COVID-19 is low in the local population. Perhaps, it is time to consider replacing this with on-the-spot quick antigen testing for more effective use of resources.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has spread globally, resulting in an ongoing pandemic. Real-time reverse transcription-polymerase chain reaction (rRT-PCR) from a viral swab is diagnostic. The most common site to take this swab is from the nasopharyngeal area; however, patients with tracheostomies represent a major challenge as they have two sources for colonization and possible infection including the nose and the trachea. We present the case of a patient who had a COVID-19 diagnostic swab through his tracheostomy, when unfortunately the swab broke, resulting in a bronchial foreign body.

ABSTRACT

Common radiological findings of COVID -19 infection include bilateral ground-glass opacities in lower lobes with a peripheral distribution. Pleural effusion is considered a rare manifestation of COVID -19 infection. We present a 52 years old patient with a three-week history of right-sided pleuritic chest pain, fever, and dyspnea. Laboratory investigations revealed high C-reactive protein and ferritin levels and a positive COVID-polymerase chain reaction (PCR) from a nasopharyngeal swab. Chest X-ray and Computed tomography (CT) identified a moderate right-sided pleural effusion, which was exudative with mixed cellularity and high Lactate dehydrogenase (LDH). Histopathology of thoracoscopic pleural biopsy didn't reveal granulomas, malignancy, or any microbiological growth. We postulate that having ruled out any other cause the effusion was likely related to the Covid-19 infection. Our case highlights that COVID-19 can present with isolated pleural effusions, therefore it should be kept as an etiology of effusions especially if other possible causes have been ruled out.

ABSTRACT

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.
