Abstract
Progressive familial intrahepatic cholestasis type 1 (PFIC1) is caused by mutations in the gene encoding the phospholipid flippase ATP8B1. Apart from severe cholestatic liver disease, many PFIC1 patients develop extrahepatic symptoms characteristic of cystic fibrosis (CF), such as pulmonary infection, sweat gland dysfunction and failure to thrive. CF is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR), a chloride channel essential for epithelial fluid transport. Previously it was shown that CFTR transcript levels were strongly reduced in livers of PFIC1 patients. Here we have investigated the hypothesis that ATP8B1 is important for proper CFTR expression and function. We analyzed CFTR expression in ATP8B1-depleted intestinal and pulmonary epithelial cell lines and assessed CFTR function by measuring short-circuit currents across transwell-grown ATP8B1-depleted intestinal T84 cells and by a genetically-encoded fluorescent chloride sensor. In addition, we studied CFTR surface expression upon induction of CFTR transcription. We show that CFTR protein levels are strongly reduced in the apical membrane of human ATP8B1-depleted intestinal and pulmonary epithelial cell lines, a phenotype that coincided with reduced CFTR activity. Apical membrane insertion upon induction of ectopically-expressed CFTR was strongly impaired in ATP8B1-depleted cells. We conclude that ATP8B1 is essential for correct apical localization of CFTR in human intestinal and pulmonary epithelial cells, and that impaired CFTR localization underlies some of the extrahepatic phenotypes observed in ATP8B1 deficiency.

The innate immune protein calprotectin promotes Pseudomonas aeruginosa and Staphylococcus aureus interaction.

Nat Commun. 2016;7:11951

Authors: Wakeman CA, Moore JL, Noto MJ, Zhang Y, Singleton MD, Prentice BM, Gilston BA, Doster RS, Gaddy JA, Chazin WJ, Caprioli RM, Skaar EP

Abstract
Microorganisms form biofilms containing differentiated cell populations. To determine factors driving differentiation, we herein visualize protein and metal distributions within Pseudomonas aeruginosa biofilms using imaging mass spectrometry. These in vitro experiments reveal correlations between differential protein distribution and metal abundance. Notably, zinc- and manganese-depleted portions of the biofilm repress the production of anti-staphylococcal molecules. Exposure to calprotectin (a host protein known to sequester metal ions at infectious foci) recapitulates responses occurring within metal-deplete portions of the biofilm and promotes interaction between P. aeruginosa and Staphylococcus aureus. Consistent with these results, the presence of calprotectin promotes co-colonization of the murine lung, and polymicrobial communities are found to co-exist in calprotectin-enriched airspaces of a cystic fibrosis lung explant. These findings, which demonstrate that metal fluctuations are a driving force of microbial community structure, have clinical implications because of the frequent occurrence of P. aeruginosa and S. aureus co-infections.

Cystic Fibrosis Revisited - a Review Study.

Med Chem. 2016 Jun 8;

Authors: Kuca K, Klimova B, Novotny M, Maresova P

Abstract
BACKGROUND: Cystic fibrosis (CF) is an incurable, chronic disease, which causes severe damages to respiratory and digestive tracts. It is the most common genetically inherited disease among caucasians. This disease is caused by defects in CF genes, the so-called mutations in cystic fibrosis transmembrane conductance regulator (CFTR) gene population. At present over 100,000 people suffer from this disease worldwide.
OBJECTIVE: The purpose of this review study is to describe the pathophysiology of CF and provide the latest information on its diagnosis and treatment therapies with respect to the improvement of patient's quality of life and emphasis on targeted specialized care.
METHOD: The methodological approaches include a method of literature review of available sources exploring the issue of cystic fibrosis both from a global and specific perspective point of view. A search was performed in the databases PubMed, MEDLINE, Web of Science, Scopus, Springer and ScienceDirect. Furthermore, other sources cited in the analyzed studies were also examined. On the basis of evaluation of these literature sources, the research issue was explored.
RESULTS: The main benefits (e.g., specialized centres for the treatment of CF exist or a new breakthrough in the gene therapy of CF has been made) and limitations (e.g., comorbidity of CF, lifelong and costly treatment, or adverse impact on patient's and caregiver's quality of life) in the treatment of narcolepsy are highlighted.
CONCLUSION: CF requires an integrated treatment approach in specialized CF centers, involving various factors contributing to a better patient's state of health in the form of relevant and well-balanced non-pharmacological and pharmacological therapies. In addition, further large scale clinical trials are needed in order to develop compounds that are aimed at the most common classes of CFTR.

[Italian Cystic Fibrosis Register - Report 2010].

Epidemiol Prev. 2016 Mar-Apr;40(2 Suppl 2):1-47

Authors: Amato A, Ferrigno L, Salvatore M, Toccaceli V, Gruppo di lavoro RIFC/ICFR Working Group

Abstract
UNLABELLED: The Italian National CF Registry (INCFR) is based on the official agreement between the clinicians of the Italian National Referral Centers for Cystic Fibrosis and the researchers of the Istituto Superiore di Sanità (National Center for Rare Diseases; National Center for Epidemiology, Surveillance and Health Care Promotion). OBJECTIVES The main aim of INCFR is to contribute to the improvement in CF patients health care and clinical management through: i. the estimates of CF prevalence and incidence in Italy; ii. the analyses of medium and long term clinical and epidemiological trends of the disesase; iii. the identification of the main health care needs at regional and national level to contribute to the Health Care programmes and to the distribution of resources. MATERIALS AND METHODS Analyses and results described in the present Report are referred to patients in charge to the Italian National Referral Centers for Cystic Fibrosis in 2010. Data were sent by Centers by means of a specific software (Camilla, Ibis Informatica). The Italian National Referral Centers for Cystic Fibrosis sent a total of 5,271 individual records; 1,112 records were excluded from the analyses due to restricted inclusion criteria. The total number of patients included in INCFR for analyses is 4,159. RESULTS INCFR database includes all prevalent cases at 1th January 2010 as well as all new diagnoses done in 2010. The present Report has been organized into 9 sections. 1. Demography: estimated 2010 CF prevalence was 7/100,000 residents in Italy; 52% of the patients were male, CF distribution showed higher frequency in patients aged 7 to 35 years. In 2010, 48.9% of the patients were more than 18 years old. 2. Diagnoses: most of the CF patients were diagnosed before two years of age (66.7%); a significant percentage of patients (11.4%) was diagnosed in adult-age. 3. New diagnoses (2010): new diagnoses were 168. Sixty-five percent of them was diagnosed before the second year of age and 17%in adulthood. No differences were observed between male and female. Incidence at birth was estimated 1/4,854 living births. 4.
GENETICS: in 95.9% of patients, 2 (or more) CFTR mutations were identified. [delta]508F mutation was the most frequent (45.1%). 5. Respiratory function: analyses were performed on 2,966 out of 3,341 patients aged 7 years or older. FEV1 (Forced Expiratory Volume in the first second) scores progressively decreased before adult age, in accordance with the natural history of the disease. 6. Nutrition: most critical periods are during the first 6 months of life and during adolescence. Fourteen per cent of the patients within 2-18 years resulted malnourished. From 18 years onwards, optimal BodyMass Index (BMI) values were detected in 36.5%of males and in 28%of females. BMI also improved during age. 7. Transplantation: in 2010, 20 patients (10 males and 10 females) were bi-pulmunary transplanted; age was comprised between 11 and 46 years, median age at transplantation was 27.5 years. Eleven out of the 20 patients resulted still alive on the 31th December 2010. 8. Microbiology: analyses were performed on 3.272 patients (887 did not report these data) and were exclusively referred to tests performed in 2010. A percentage of 34 patients, younger than 18 years of age, was characterized by the presence of Pseudomonas aeruginosa compared to 61.8% of the older patients. Prevalence of Burkholderia Cepacia was 0.8% in patients aged up to 17 years; in patients aged more than 17 years, prevalence was 6.8%. Staphylococcus aureus meticillino sensitive prevalence was not correlated with patients' age. 9.
MORTALITY: 34 patients aged from 0 to 45 years died in 2010 (16 males and 18 females). Respiratory insufficiency was the main cause of death (73.5%). CONCLUSIONS The report aims at being an instrument for CF community, with particular attention to the needs of patients and their families. Information collected within INCFR are an important starting point for further studies from health care perspectives. Finally, INCFR represents an important tool to foster research and innovative treatment for CF, as the rareness of the disease is a constraint to clinical trials and other studies set-up. A significant subset of data are regularly sent to the European Registry of Cystic Fibrosis.

Bioelectrical impedance in young patients with cystic fibrosis: Validation of a specific equation and clinical relevance.

J Cyst Fibros. 2016 Jun 8;

Authors: Charatsi AM, Dusser P, Freund R, Maruani G, Rossin H, Boulier A, Le Bourgeois M, Chedevergne F, de Blic J, Letourneur A, Casimir G, Jais JP, Sermet-Gaudelus I

Abstract
BACKGROUND: Body composition (BC) analysis based on bioelectrical impedance analysis (BIA) provides conflicting results. The purpose of the study was to validate an equation specific for young patients with cystic fibrosis (CF), describe their BC and investigate its association with lung function.
METHODS: Fifty-four young CF patients were evaluated by BIA and dual X-ray absorptiometry (DXA). An empirically derived CF-specific equation for fat-free mass (FFM) estimation by BIA was elaborated after stepwise multivariate regression and the agreement between BIA and DXA was assessed by Bland-Altman plots. The association between BC and lung function was investigated by regression analysis.
RESULTS: The mean difference between the BIA and DXA assessment was close to zero. A total of 22.5% of patients (n=9) presented a FFM z-score≤-2. They had a worse pulmonary function and diaphragmatic impairment. Among these 9 patients, 7 had a normal BMI z-score>-1.
CONCLUSIONS: BIA, based on a CF-specific equation, is a reliable method for BC assessment and allows the identification of patients at risk of nutritional degradation and bad respiratory prognosis.

Nutritional status of children with clinical conditions.

Clin Nutr. 2016 May 26;

Authors: Murphy AJ, Hill RJ, Buntain H, White M, Brookes D, Davies PS

Abstract
BACKGROUND & AIMS: Nutritional status is an important consideration in many pediatric clinical conditions. This paper aimed to examine and compare the nutritional status, represented by body cell mass (BCM), of children with cancer, Crohn's disease (CD), cystic fibrosis (CF) and anorexia nervosa (AN).
METHODS: Anthropometry was measured and BCM was calculated from whole body potassium-40 counting in 259 children being treated for clinical conditions (n = 66 cancer; n = 59 AN; n = 75 CF; n = 59 CD) and 108 healthy children. BCM was adjusted for height (BCMI) and expressed as a Z-score relative to laboratory reference data.
RESULTS: The CD (-0.80 ± 1.61; p = 0.0001) and AN (-1.13 ± 0.99; p = 0.0001) groups had significantly lower BMI Z-score than the healthy control (0.13 ± 0.75), cancer (0.50 ± 1.40) and CF groups (-0.09 ± 0.95). The cancer (-1.16 ± 1.60; p = 0.0001), CD (-1.13 ± 1.36; p = 0.0001) and AN (-0.97 ± 1.18; p = 0.0001) groups had significantly reduced BCM compared to the healthy control (0.07 ± 0.93) and CF group (0.31 ± 1.08). According to BCMI Z-score, 42.4% of patients with cancer, 41.7% of the patients with CD, 27.1% of patients with AN, and 4.0% of patients with CF were considered malnourished.
CONCLUSIONS: This study demonstrates that children undergoing treatment for clinical conditions may have alterations in BCM, independent of BMI. Children with cancer, CD and AN all had a high prevalence of malnutrition. Assessment of body composition, not just body size, is vital to understand nutritional status in children with clinical conditions.

Nontuberculous mycobacteria in cystic fibrosis patients on the Island of Gran Canaria. A population study.

J Infect Chemother. 2016 Jun 1;

Authors: Campos-Herrero MI, Chamizo FJ, Caminero JA, Gilarranz R, Cabrera G, Cuyás J

Abstract
OBJECTIVE: To determine the prevalence of nontuberculous mycobacteria (NTM) colonization and disease in cystic fibrosis (CF) patients.
PATIENTS AND METHODS: All the CF patients followed-up from 2002 to 2012 with three acid-fast bacilli (AFB) cultures were included. The American Thoracic Society (ATS) criteria for NTM lung disease were applied.
RESULTS: Forty-four of the 53 patients being followed-up were included. The mean time of follow-up was 7.0 years. A total of 18 patients (40.9%) were NTM positive. The NTN mean annual prevalence was 14.1%. The risk of Mycobacterium abscessus complex was higher in the group of 10-14 years-old (p < 0.001). Ten patients (22.7% of the entire cohort) met the ATS microbiological criteria. The mean annual prevalence of NTM disease was 10.4%. Seven patients (four with Mycobacterium simiae and three with M. abscessus complex) with multiple positive cultures, positive AFB smears and clinical worsening were treated. Three patients with M. simiae and none of those with M. abscessus were cured.
CONCLUSIONS: Overall NTM prevalence of colonization and disease were high in our CF patients. Patients <15 years old had a higher risk of M. abscessus complex colonization. Multiple positive cultures or positive AFB smears were associated with disease.

Cystic fibrosis in Latin America-Improving the awareness.

J Cyst Fibros. 2016 Jun 1;

Authors: Silva Filho LV, Castaños C, Ruíz HH

Abstract
The burden of cystic fibrosis (CF) in Latin America is being increasingly recognized and is significant compared with other regions of the world. In this short communication, we assess the current situation in some Latin American countries and make suggestions for possible directions for future focus. We discuss the work that remains in deciphering how the various genetic, environmental and medical factors interact and influence outcomes in different ethnic groups. We also consider the need for consistency in both research and access to services across Latin America, including CF registries, neonatal screening programs, access to specialized CF healthcare practitioners, transition to adult clinics and treatment regimens. Progress in these areas is likely to build on the advances to date, and improve the lives of patients in Latin America who are affected by this debilitating and life-limiting disorder.
