The varied presentation of acute respiratory illness from SARS-CoV-2 poses a diagnostic challenge to the physician. The classic presentation of fever, cough and shortness of breath is often not reported in a number of patients. We report a case of acute respiratory illness in a middle-aged asthmatic man who presented with acute severe bronchospasm.
A 59-year-old male patient presented in emergency department with a history of shortness of breath for 5 days and he was immediately shifted to the screening intensive care unit (ICU) as dyspnea was rapidly increasing. He was a known case of bronchial asthma for 4 months and type 2 diabetes for 2 years, on regular medical management. He denied any history of fever and cough or any relevant contact history. On arrival in the ICU, he was conscious and oriented, but dyspneic, using accessory muscles of respiration with respiratory rate of 28 per minute and maintaining SpO2 of 86% on room air. The rest of the hemodynamic parameters were stable. Lung ultrasonography showed B profile in zone 1 of right lung with shredding. The other lung zones were normal. Oxygen supplementation by face mask, and nebulization with salbutamol were started and intravenous hydrocortisone 100 mg was administered. Nasal and throat swabs were sent for real time polymerase chain reaction (RT-PCR) for SARS-CoV-2 identification. However, despite of medical management, respiratory rate increased to 40 and SpO2 decreased to 65-70% and altered sensorium was also noted. Immediately, endotracheal intubation was performed by videolaryngoscope after administering intravenous propofol 2 mg/kg and rocuronium 1.2 mg/kg. Mechanical ventilation was initiated by volume-controlled ventilation with a tidal volume of 350 ml, respiratory rate of 18/m and an initial PEEP of 5 cm H2O. A peak airway pressure of 45 cm H2O and a plateau airway pressure of 25 cm H2O was noted which further supported the diagnosis of acute bronchospasm. Intravenous magnesium sulphate of 2 gm administered followed by intravenous ketamine infusion which decreased peak airway pressure to 35 cm H2O and SpO2 increased to 95%. RT- PCR revealed that the patient was infected with SARS-CoV-2.
Viral respiratory infections are often implicated as an inciting event for acute exacerbation of bronchial asthma and asthma is associated with adverse outcome in patients with viral respiratory infection. SARS-CoV-2 exhibited a diverse range of clinical symptoms including the classic triad of fever, cough and shortness of breath. However, majority of the large series did not actually mention the proportion of asthmatic patients who were infected with SARS-COV-2. Richardson et al. mentioned 9% of the cases had bronchial asthma as a comorbidity but the presentation as acute exacerbation of asthma was not described. The presentation in our patient was unique, as he presented with only rapidly progressive dyspnea without any other clinical feature. In the era of current pandemic, SARS-CoV-2 must be kept as a differential diagnosis in any patient who is presenting with acute exacerbation of asthma.
