ReviewGastrointestinal and Hepatobiliary Disease in Cystic Fibrosis.
Cystic fibrosis (CF) is a multiorgan disease, and gastrointestinal (GI) manifestations can contribute to significant morbidity and mortality for individuals with CF. Up to 85% of patients with CF experience GI symptoms, thus addressing the GI aspects of this disease is paramount. With the advent of highly effective CF transmembrane conductance regulator modulators that are increasingly available, many individuals with CF now have significantly improved life expectancy. ⋯ In addition, as individuals have increased longevity, it has become essential for care providers to be aware of topics such as hepatobiliary disease and colorectal cancer screening. An understanding of the wide scope of GI manifestations in CF can enable providers to optimize the overall health and well-being of their patients. In this review, we aim to provide an up-to-date overview of key aspects of GI and hepatic disease in CF.

Cystic fibrosis (CF) is now more common in adults than children in countries with well-developed health care systems. The number of adults continues to increase and will further increase if the new cystic fibrosis transmembrane conductance regulator (CFTR) modulators are disease modifying. Most of the complex morbidity and almost all the mortality of CF occur in adults and will increasingly follow this pattern even with new effective modulator therapies. ⋯ Changes in health care systems will require current models of care to adapt to provide care for the large number of adult patients. With increasing survival and age, many are likely to have both CF morbidities and additional diseases of aging. New models are needed for health care delivery for this expanding population with complex medical conditions.

With the improving survival of cystic fibrosis (CF) patients and the advent of highly effective cystic fibrosis transmembrane conductance regulator therapy, the clinical spectrum of this complex multisystem disease continues to evolve. One of the most important clinical events for patients with CF in the course of this disease is an acute pulmonary exacerbation. ⋯ This work has now led to a number of large scale clinical trials with the goal of improving the treatment paradigm for CF pulmonary exacerbation. The primary goal of this review is to provide a summary of the pathophysiology, the clinical epidemiology, microbial epidemiology, outcome and the treatment of CF pulmonary exacerbation.

ReviewTreating the Airway Consequences of Cystic Fibrosis Transmembrane Conductance Regulator Dysfunction.
In cystic fibrosis (CF), absent or dysfunctional CF transmembrane conductance regulator (CFTR) on the surface of airway epithelial cells causes abnormal mucociliary clearance, leading to chronic endobronchial infection and inflammation, in turn resulting in life-shortening progressive obstructive lung disease and structural airway damage. Fortunately, CF-specific therapies have been developed that improve lung function and reduce pulmonary exacerbations, contributing significantly to improved survival over the past 4 decades. ⋯ Determining which therapies to utilize can be challenging, as there is variable evidence for each treatment, differing national guidelines, few head-to-head studies, potential for drug-drug interactions, and synergistic toxicities, as well as issues with burden of care. In this review, we summarize the mechanism of action and available evidence, and compare national guidelines for each major medication used to treat the airway consequences of CFTR dysfunction.
