RÉSUMÉ
The effects of the concomitant infection by COVID-19 and Burkholderia cepacia (Bc) in CF are not known. We describe the case of a 34 years woman with CF, colonized by Bc and found SARS-CoV2 positive. In the first hospital week she suffered acute respiratory failure and chest imaging showed interstitial involvement and multiple thickenings. She was treated with antibiotics, dexamethasone, remdesivir and heparin, with gradual improvement and discharge at day 20th. The reciprocal role of SARS-CoV-2 and Bc, their potential interactions and the contribution of the individual therapies to the favourable outcome are unclear. It is debatable whether it was SARS-CoV2 that triggered a Bc pulmonary exacerbation or if the chronic Bc infection facilitated the development of a COVID-19 more aggressive than usually seen in CF. If the latter hypothesis were confirmed by similar cases, Bc colonization should be regarded as a risk factor for severe COVID-19 expression in CF.

AIM: The aim of the present study is to retrospectively evaluate the effectiveness of noninvasive pressure ventilation in the 24-bed Pediatric Intensive Care Unit (PICU) of the G. Gaslini Institute during a 24-month period. METHODS: A retrospective analysis of the characteristics (pH, CO2, SpO2, respiratory rate, oxygen requirement) of patients treated with noninvasive mechanical ventilation for different acute pathologies has been performed. RESULTS: Twenty patients (mean age 7.4+/-0.28 years) with acute respiratory failure due to different pathologies were treated with noninvasive mechanical ventilation. They were divided into 2 groups: the hypoxic group, suffering from pulmonary diseases, and the hypercapnic group, presenting a failure of the mechanical strength or increased dead space. Modalities of ventilation were pressure assisted/controlled or pressure support, delivered through nasal or facial masks. Fifteen out of 20 patients presented a marked improvement of oxygenation and ventilation. Mean times of treatment were 69 and 200 h in the hypoxic and hypercapnic groups, respectively. Five patients required intubation. Two patients presented reversible skin lesions over the nasal bridge. CONCLUSIONS: Noninvasive ventilation can be used in PICU. Major advantages regard immunocompromised children and patients with exacerbations from chronic respiratory diseases, whereas the exact role of noninvasive positive pressure ventilation in patients affected by acute respiratory distress syndrome is still controversial.

AIM: To evaluate clinical and genetic factors, besides pancreatic insufficiency, associated with increased risk of cystic fibrosis-related diabetes. METHODS: Case-control (1:1) study on 138 cystic fibrosis patients. Data were collected on gender, age at diagnosis, reason for cystic fibrosis diagnosis, family history of type 1 or 2 diabetes mellitus, pre-existing severe liver disease, and class of cystic fibrosis transmembrane regulation mutation. Moreover, information was obtained on lung involvement and degree of exocrine pancreatic insufficiency evaluated 1 year before the diagnosis of cystic fibrosis-related diabetes in patients and age-matched controls. RESULTS: Compared to controls, patients with cystic fibrosis-related diabetes had a higher probability of having already been diagnosed with liver disease (16.7% versus 1.7%, OR = 11.6, 95% CI 1.43-93.0). Moreover, in the year before diabetes onset, cases had slightly worse pulmonary function compared to controls (FEV1 = 58.4 +/- 27% predicted versus 67.4 +/- 21% predicted; p = 0.05). No significant effects related to the other factors considered were found. CONCLUSION: Severe liver disease was found to significantly increase the risk of developing cystic fibrosis-related diabetes. Patients with liver disease should be scheduled for earlier diabetes screening in order to identify and possibly treat glucose intolerance.
