Abstract

Novel coronavirus infection presents with greater severity in individuals with comorbid chronic lung diseases. Bronchiectasis is an illness characterized by permanent enlargement of the airways, presenting with chronic cough and sputum production and vulnerability to lung infections. Bronchiectasis is not a common comorbid disease in patients with COVID‑19 disease and bronchiectasis exacerbation rates were decreased during the pandemic. However, COVID‑19 disease is associated with worse outcomes in patients with bronchiectasis and patients with bronchiectasis are more susceptible to SARS‑CoV‑2 infection development. Pseudomonas putida is an opportunistic pathogen, causing infections mostly in immunocompromised hosts and is not a frequent bacterial colonizer in patients with bronchiectasis. This present study reports a rare case of exacerbation of bronchiectasis by Pseudomonas putida complicating COVID‑19 disease in an immunocompetent 70‑year‑old woman. Clinicians should be aware that SARS‑CoV‑2 infection is probably a precipitating factor of bronchiectasis exacerbation while bronchiectasis is a risk factor for greater severity of SARS‑CoV‑2 infection.

Introduction

Bronchiectasis is a chronic pulmonary disease characterized by a vicious cycle of infection and inflammation of the airways, leading to permanent structural lung damage (1). The incidence of the disease has risen since 2000 and there are ≤100,000 individuals in the United States with bronchiectasis, while the disease is also diagnosed more frequently worldwide (2). Bronchiectasis can be detected at all ages and generally presents with chronic cough, sputum production and recurrent lower respiratory tract infections (2). Bronchiectasis is usually post-infection while several lung and systemic diseases are associated with its development (3).

Bronchiectasis exacerbation is a generally infectious clinical condition characterized by deterioration of chronic symptoms with negative consequences on patient prognosis, caused mostly by bacterial microorganisms. Frequent bronchiectasis exacerbations lead to lung damage and rapid decline of lung function (4). Among numerous microorganisms associated with bronchiectasis, Pseudomonas aeruginosa is one of the most frequent and important, with its isolation being associated with frequent exacerbations, poor quality of life and greater possibility of hospitalization and mortality (5).

Novel coronavirus SARS-CoV-2, which causes COVID-19 disease, has exhibited a rapid spread worldwide, becoming the biggest threat ever observed from a pandemic (6). COVID-19 patients have a relatively low rate of bacterial co-infection or bacterial secondary infection. These infections are commonly observed in the critically ill patients (7,8). In addition, it has been reported that bronchiectasis exacerbation frequency is significantly decreased during COVID-19 pandemic (9).

Pseudomonas putida is a gram-negative, aerobic saprophytic bacterium that is a common colonizer of soil, plants and water. Due to its remarkable metabolism, it is used as a cell host for synthetic biology and metabolic engineering (10). It has been reported as an opportunistic pathogen causing sepsis in immunocompromised patients and infections among hospitalized patients experiencing invasive procedures due to its ability to contaminate medical solutions (11,12).

The present study reports a novel case of a bronchiectasis exacerbation due to Pseudomonas putida complicating COVID-19 disease.

Case presentation

A 70-year-old female, non-smoker, patient presented to the Emergency Department of Laiko General Hospital (Athens, Greece) with complaints of fever, runny nose, cough and progressive dyspnea at rest over the previous 10 days. She had a medical history of gastroesophageal reflux, arterial hypertension, hyperlipidemia, asthma, hypothyroidism, obesity with a body mass index (BMI) 33 kg/m2, obstructive sleep apnea (OSA), pulmonary embolism one year ago and appendectomy. Her medications included pantoprazole, irbesartan/hydrochlorothiazide, atorvastatin, inhaled fluticazone/salmeterol, montelucast, levothyroxine sodium and rivaroxaban. She was also using continuous positive airway pressure therapy for OSA.

Clinical evaluation revealed a febrile patient with wheezing and crackles on auscultation at the bases of both lungs. Clinical examination of the other systems was unremarkable. Blood pressure was 110/60 mmHg, heart rate was 80 beats per min, oxygen saturation was 90% on room air and body temperature 38.5˚C. Electrocardiography did not reveal abnormal findings on admission.

Arterial blood gas analysis showed pO2 52 mmHg, pCO2 32 mmHg, pH 7.53 and HCO3 26.7 mmol/l on room air. Chest X-Ray showed patchy diffuse infiltrates in both lungs mostly in the periphery of the left lung (Fig. 1A).

Laboratory investigation included complete blood cell count, basic biochemistry serum and urine parameters and coagulation testing. Laboratory findings included hemoglobin 13.1 g/dl (normal 12-16 g/dl), hematocrit 39.5% (normal 38-47%), white blood cells (WBC) 4.28x103/µl (normal 4-11x103/µl), neutrophils 2.8x103/µl (normal 1.5-6.6x103/µl), lymphocytes 1.24x103/µl (normal 1.2-3.4x103/µl), platelets 145x103/µl (normal 140-440x103/µl), serum glucose 110 mg/dl (normal 72-106 mg/dl), blood urea nitrogen 57 mg/dl (normal 15-43 mg/dl), creatinin 1.36 mg/dl (normal 0.6-1 mg/dl), C-reactive protein 18.78 mg/l (normal <6 mg/l), ferritin 145 ng/ml (normal 15-150 ng/ml), prothrombin time (PT) 28.5 sec (normal 11-13 sec), activated PTT 52.2 sec (normal 29-40 sec), international normalized ratio (INR) 2.16 (normal 0.9-1.2) and d-dimers 1.21 µg/ml (normal <0.5 µg/ml). The other blood biochemistry parameters were normal. Urinalysis revealed 1-2 WBCs per high power field (PHF; normal 0-2 PHF), 0-2 RBCs PHF (normal 0-2 PHF), pH 6 (normal 4.5-8), specific gravity 1.020 (normal 1.005-1.025), nitrites negative and leukocyte esterase negative.

The patient was tested for coronavirus and had positive detection of SARS-CoV-2 nucleic acid in examined nasopharyngeal sample using reverse transcription-PCR.

The patient was unvaccinated for SARS-CoV-2. She was transferred to the COVID-19 unit and received oxygen therapy with Venturi mask delivering 35% oxygen and intravenous dexamethasone, remdesivir and subcutaneous enoxaparin. After three days of hospitalization she presented with resolution of the fever and improvement of oxygen level.

On the fifth day of hospitalization, fever reoccurred and the patient presented with worsening cough with green sputum, with reduction in partial pressure of oxygen, changes in findings from lung auscultation with rhonchi sounds found in all lung fields and worsening infiltrates on chest X-ray (Fig. 1B). The patient received oxygen with Venturi mask delivering 50% oxygen and intravenous piperacillin-tazobactam empirically. She underwent high resolution computed tomography of the chest showing bronchiectasis and nodular ground glass opacifications mostly with peripheral and subpleural distribution in both lungs (Fig. 2A-C).

Sputum culture was performed which revealed the presence of Pseudomonas putida. Antimicrobial susceptibility testing showed that the microorganism is pansusceptible. The patient presented with improvement after three days of piperacillin-tazobactam administration. She had gradual recovery and she was discharged on the 12nd day of hospitalization without the need of supplemental oxygen and with instructions to receive oral ciprofloxacin in order to have overall a 14-day antibiotic course.

Discussion

The case is notable for two reasons. First, it is, to the best of the authors' knowledge, the second case in literature mentioning bronchiectasis exacerbation by Pseudomonas putida. The first case was reported by Fujita et al (13) in 1998, in a 57-year-old woman with bronchiectasis and without serious comorbidities. In that case, the patient was non-immunocompromised, had a known history of bronchiectasis, presented with increase in the volume and purulent nature of the sputum and mild hemoptysis and had a right lower lobe consolidation on imaging. The patient in the current study was also an immunocompetent host. She did not present with hemoptysis or consolidation on chest computed tomography scan and she had no known history of bronchiectasis. Pseudomonas putida has emerged as an opportunistic pathogen for non-immunocompetent hosts, causing bacteremia, wound and ocular infections, urinary tract and lower respiratory tract infections, central venous catheter and soft tissue infections in this patients population (14).

Second, the case in the current study indicated that SARS-CoV-2 infection precipitated bronchiectasis exacerbation. Mask-wearing and social distancing during the COVID-19 pandemic were associated with a marked decrease in bronchiectasis exacerbation frequency (15). This decrease was probably noticed due to a reduction in circulating viruses and in traffic-related air pollution, documented during the pandemic (9). However, SARS-CoV-2 infection seems to result in co-infections and exacerbations in patients with bronchiectasis. Lopinto et al (16) reported the first case of acute exacerbation of bronchiectasis, precipitated by COVID-19 disease and complicated by severe hemoptysis. In addition, Faqihi et al (17) describe a case of co-infection of Bordetella bronchiseptica and novel coronavirus in a young patient with idiopathic bronchiectasis leading to critical illness and requirement of mechanical ventilation. One may hypothesize that the novel virus triggers acute bronchial inflammation and exacerbation of the chronic disease of airways.

It has been reported that ~2% of patients with COVID-19 have underlying lung disease, which is related to severe clinical manifestations and higher mortality compared with those without chronic lung diseases (18). Bronchiectasis is an uncommon comorbidity observed in COVID-19 patients and thus research about manifestations and clinical outcome of COVID-19 disease in patients with bronchiectasis is limite (19,20). Choi et al (20), in which 8,070 patients with COVID-19 were enrolled, report that the patients with bronchiectasis are significantly older (P<0.001) and more frequently exhibit pulmonary comorbidities, including asthma. The researchers also reported that the rate of SARS-CoV-2 infection is relatively higher in patients with bronchiectasis compared with those without bronchiectasis and that COVID-19 patients with bronchiectasis present with a higher rate of supplemental oxygen and extracorporeal membrane oxygenation requirement and higher mortality than those without bronchiectasis, indicating that impaired mucociliary clearance and bronchial inflammation possibly increase their vulnerability to, and severity of, COVID-19(20). Larger prospective studies may be needed to address issues concerning patients with bronchiectasis experiencing SARS-CoV-2 infection.

In conclusion, the present study detailed a rare case of exacerbation of bronchiectasis by Pseudomonas putida complicating COVID-19 disease. Pseudomonas putida can cause pulmonary infection and bronchiectasis exacerbation even in immunocompetent hosts (13). Moreover, SARS-CoV-2 infection should be considered a precipitating factor of bronchiectasis exacerbation, while the presence of bronchiectasis make individuals susceptible to development and greater severity of SARS-CoV-2 infection.
