The chloride channel dysfunction caused by deleterious cystic fibrosis transmembrane conductance regulator (CFTR) variants generally correlates with severity of (CF). However, 3 adults bearing the common severe variant p.Phe508del (legacy: F508del) and a deletion in an ivacaftor binding region CFTR (p.Phe312del; legacy: F312del) manifested only elevated sweat concentration (sw[Cl-]; 87-105 mEq/L). A database review 25 individuals F312del CF-causing revealed sw[Cl-] (75-123 mEq/L) variable CF...

We determined the density in Hounsfield units of mesenteric, retroperitoneal, and subcutaneous fat on CT scans made 41 patients with biopsy-proved cirrhosis compared results these locations 34 control subjects, an attempt to quantify changes cirrhosis. The mean densities were -56, -107, -111 H, respectively. corresponding subjects -118, -124 H. mesenteric was 50% greater than that their (p less .0001), 48% retroperitoneal .0001). anterior abdominal wall -96 H -119 for posterior wall. -109...

Single-center studies have suggested that up to 70% of adults with cystic fibrosis (CF) lower than expected bone mineral density (BMD), substantially higher the 25% prevalence reported from national registries. We determined low BMD in CF at our center and assessed risk factors for BMD. This retrospective cohort study was conducted all patients ≥18 years age who had a dual-energy X-ray absorptiometry (DXA) scan performed Johns Hopkins Adult Cystic Fibrosis between 2010 2018. Prevalence...

Abstract Catamenial haemoptysis, the expectoration of blood during menses, has not been extensively reported in cystic fibrosis (CF) literature. We describe four cases (age range: 25–34 years) catamenial haemoptysis across CF centres United States. These may represent thoracic endometriosis versus hormonal fluctuations airway inflammation or infection resulting bronchial artery bleeding. identify common and nuanced management strategies including use pro‐coagulants, hormone contraceptives,...

Cystic fibrosis (CF) was historically a disease largely afflicting children. Due to therapeutic advancement, there are now more adults with CF than In the past decade, medications became available that treat underlying cause of and dramatically improving lung function as well quality quantity life for people CF. As result, women having babies. We gathered panel experts in care, family planning, high risk obstetrics, nutrition, genetics review current literature on pregnancies provide care...

Abstract Background Cholangiocarcinoma is a rare gastrointestinal malignancy that arises within the intrahepatic, perihilar, and/or extrahepatic bile ducts. Individuals with cystic fibrosis are at increased risk for malignancies. The most common in colon cancer, but other malignancies also occur greater rates than general population. Case presentation We present case of rapidly progressive metastatic intrahepatic cholangiocarcinoma an individual who was 5 months postpartum, incidentally...
