Allergic bronchopulmonary aspergillosis as an initial manifestation of cystic fibrosis: Diagnostic and therapeutic implications in the era of CFTR modulators.

Allergic bronchopulmonary aspergillosis (ABPA) results from complex hypersensitivity reactions to , which often occur in patients with asthma, cystic fibrosis (CF), or CF transmembrane conductance regulator (CFTR)-related disorders. Genetic predisposition, particularly variants of the gene, probably plays a significant role in the development of ABPA. We present the case of a 20-year-old male with ABPA and bronchiectasis that was initially misdiagnosed as a result of normal sweat chloride values and negative first-level genetic testing results.

Allergic bronchopulmonary aspergillosis in a lung transplant recipient treated with mepolizumab.

Allergic bronchopulmonary aspergillosis (ABPA) is a complex hypersensitivity reaction to Aspergillus spp. ABPA diagnosis may be challenging due to its non-specific presentation. Standard ABPA treatment consists of systemic corticosteroids and antifungal agents.

Antifungal drug penetration in soft tissue abscesses: a comparative analysis.

Background: Invasive fungal infections (IFIs) are severe and difficult-to-treat infections affecting immunocompromised patients. Antifungal drug penetration at the site of infection is critical for outcome and may be difficult to achieve. Data about antifungal drug distribution in infected human tissues under real circumstances of IFI are scarce.

Successful pregnancy in a cystic fibrosis patient with a severe impairment of lung function receiving Elexacaftor-Tezacaftor-Ivacaftor.

Before the arrival of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) modulators women with CF and impaired lung function were experiencing a high risk of complications and mortality during and the years after pregnancy. The arrival of the highly efficient CFTR modulator, Elexacaftor-Tezacaftor-Ivacaftor (ETI) resulted in an improvement of lung function, quality of life and fertility. Here we report a case of successful pregnancy and uncomplicated delivery for a CF patient with severely impaired lung function receiving ETI prior to conception.

[When to consider lung transplantation?].

Pulmonary transplantation remains the ultimate therapeutic option for selected patients with an advanced pulmonary disease and terminal respiratory insufficiency when all other therapeutic options have been exhausted. The optimal time-frame to proceed to a first discussion and evaluation about lung transplantation may be difficult to determine. This article describes the pathway of a patient towards lung transplantation and summarizes the criteria, which may help to timely identify eligibility for this therapeutic modality.

[Systemic biomarkers in respiratory tract infections].

Respiratory tract infections represent a major cause of morbidity and mortality despite the progress made in their diagnosis and treatment. Since the clinical presentation of a viral or bacterial infection is often similar, the identification of a biomarker that could guide the clinician whether or not to introduce an antibiotic therapy is crucial. C-reactive protein and procalcitonin are the most commonly used biomarkers as a diagnostic tool for respiratory tract infections.
