Abstract
Worldwide, over 2 billion children under the age of 5 experience stunting, wasting, or are underweight. Malnutrition contributes to 45% of all deaths in this age group (approximately 3.1 million deaths) [1]. Poverty, food insecurity, suboptimal feeding practices, climate change, and conflict are all contributing factors. Malnutrition causes significant respiratory problems, including increased risk of respiratory infections, impaired lung function, and increased risk of subsequent adult respiratory disease, including asthma, COPD, and lung cancer. Childhood malnutrition not only has serious consequences for children's health but it also has numerous consequences on wellbeing and educational attainment. Childhood malnutrition is a complex and multifaceted problem. However, by understanding and addressing the underlying causes, and investing in prevention and treatment programs, it is possible to maximize children's health and wellbeing on a global scale. This narrative review will focus on the impact of childhood malnutrition on lung development, the consequent respiratory disease, and what actions can be taken to reduce the burden of malnutrition on lung health.

Tamer G, Arets HGM, van der Ent CK, van Santen HM, van der Kamp HJ. BMI increase during early childhood in boys with cystic fibrosis and early adrenarche. Pediatr Pulmonol 2024. [PMID: 38270329 DOI: 10.1002/ppul.26861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 11/21/2023] [Accepted: 01/02/2024] [Indexed: 01/26/2024]
Abstract
BACKGROUND Increase in body mass index (BMI) in early childhood (1-6 years) was found to be a contributing factor for impaired final height in boys with Cystic Fibrosis (CF). Early adrenarche (before age 9 years in boys) may contribute to an impaired final height by triggering an early acceleration of bone age resulting in a compromised growth spurt during puberty. We aimed to analyze the timing of adrenarche in boys with CF and to associate BMI increase in early childhood to timing of adrenarche. METHODS Boys with CF, aged 8-9 years, visiting the CF expertize center Utrecht were included. Since 2018, anthropomorphic, pubertal and endocrine data were collected. Early adrenarche in boys was defined as a dehydroepiandrosterone sulfate (DHEAS) ≥ 1 µmol/L before the age of 9 years. RESULTS Thirteen boys (mean age 8.55 ± 0.27 years) were enrolled. The median (IQR) DHEAS-level was 1.3 µmol/L (0.71-2.40). Eight boys (61.5%) had an early rise in DHEAS-levels ≥ 1 µmol/L. Mean increase in BMI Z-score between 1 and 6 years of age (ΔBMI1-6 ) was -0.07 ± 0.86. A significant correlation was found between ΔBMI1-6 and DHEAS-levels at the age of 8-9 years (r = 0.624, p = 0.040). In five boys with early rise in DHEAS, accelerated bone age was found (average 1.55 ± 0.96 years). CONCLUSION In this small cohort, 61.5% of boys with CF between 8 and 9 years had an early rise of DHEAS, which was correlated to ΔBMI1 -6 between 1 and 6 years. Early adrenarche may be caused by ΔBMI1 -6 .

Abstract
INTRODUCTION Over the last ten years an increasing prevalence and incidence of non-tuberculous mycobacteria (NTM) has been reported among patients with cystic fibrosis (CF) Viviani (J Cyst Fibros, 15(5):619-623, 2016). NTM pulmonary disease has been associated with negative clinical outcomes and often requires pharmacological treatment. Although specific guidelines help clinicians in the process of diagnosis and clinical management, the focus on the multidimensional assessment of concomitant problems is still scarce. MAIN BODY This review aims to identify the treatable traits of NTM pulmonary disease in people with CF and discuss the importance of a multidisciplinary approach in order to detect and manage all the clinical and behavioral aspects of the disease. The multidisciplinary complexity of NTM pulmonary disease in CF requires careful management of respiratory and extra-respiratory, including control of comorbidities, drug interactions and behavioral factors as adherence to therapies. CONCLUSIONS The treatable trait strategy can help to optimize clinical management through systematic assessment of all the aspects of the disease, providing a holistic treatment for such a multi-systemic and complex condition.

Abstract
Background: Ivacaftor, the first CFTR modulator drug, leads to significant long-term improvement in lung function and weight gain. The mechanism as well as the long-term impact of ivacaftor on weight, resting energy expenditure (REE) and body composition remains to be explored. Methods: This prospective observational study included 18 people with CF (pwCF) (age: median (range) 20 (6-58) years) carrying at least one CFTR gating mutation commencing ivacaftor. Assessments of body composition, REE and laboratory investigations were performed at baseline and 6, 12 and 24 months after treatment initiation. Results: Treatment with ivacaftor was associated with a significantly positive change in BMI z-score at 24 months. Fat mass (mean (95% CL) of 6.5 kg (4.0; 9.0) from baseline, p = 0.0001), but not fat-free mass changed under ivacaftor treatment. There was a significant positive correlation between weight and fat mass change. Overall, there was no significant change in measured REE from baseline (mean (95% CL) of 108 kcal/d (-12; 228), p = 0.07) in our cohort. Pancreatic function and other nutritional markers did not change with treatment, with the exception of an increase in serum vitamin A levels (p = 0.006). Conclusion: The weight gain observed in ivacaftor treated pwCF is predominantly secondary to increases in fat mass warranting early counseling of people starting on CFTR-modulating treatment with respect to healthy diet and physical exercise.

Abstract
RATIONALE Low body mass index (BMI) may influence lung transplant decisions for patients with advanced cystic fibrosis (CF) lung disease. OBJECTIVE Determine whether patients with advanced CF lung disease and BMI ≤17 kg/m2 are less likely to be listed for lung transplant or have a higher risk of death without listing compared to those with higher BMI. METHODS Using merged United Network for Organ Sharing and CF Foundation Patient Registries, we identified adults with onset of advanced lung disease (FEV1 ≤ 40% predicted) between May-2005 and December-2016. We analyzed survival using competing risks regression with cause-specific risks of listing for lung transplant and death without listing. BMI ≤ 17 kg/m2 was our predictor. MEASUREMENTS AND MAIN RESULTS Among 5,121 CF patients with advanced lung disease, 23% were listed for lung transplant (n = 1,201), 23% died without listing (n = 1,190), and 44% were alive without listing (n = 2,730) as of December-2016. Patients with BMI ≤ 17 kg/m2 were less likely to be listed for transplant (HR 0.69; 95% CI 0.57, 0.83) and more likely to die without listing (HR 1.63; 95% CI 1.41, 1.88). We identified important regional variations in the likelihood of referral and listing, based on BMI. CONCLUSIONS Patients with advanced CF lung disease and BMI ≤ 17 kg/m2 are less likely to be listed for lung transplant and have a higher risk of dying without listing, compared to those with higher BMI. Regional differences suggest access to transplant for malnourished CF patients may be limited by location.

Abstract
IMPORTANCE The prevalence of overweight (body mass index [BMI] = 25-29.9 [calculated as weight in kilograms divided by height in meters squared]) and obesity (BMI ≥30) is increasing among patients with cystic fibrosis (CF). However, it is unclear whether there is a benefit associated with increasing weight compared with the reference range (ie, normal) in CF. OBJECTIVE To evaluate the association of altered BMI or body composition and clinical outcomes in patients with CF. DATA SOURCES For this systematic review and meta-analysis, the literature search was conducted November 2, 2020, of 3 databases: MEDLINE (via PubMed), Embase, and Cochrane Central Register of Controlled Trials. STUDY SELECTION Patients older than 2 years diagnosed with CF with altered body composition or BMI were compared with patients having the measured parameters within the reference ranges. Records were selected by title, abstract, and full text; disagreements were resolved by consensus. Cohort studies and conference abstracts were eligible; articles with no original data and case reports were excluded. DATA EXTRACTION AND SYNTHESIS Two authors independently extracted data, which were validated by a third author. Studies containing insufficient poolable numerical data were included in the qualitative analysis. A random-effects model was applied in all analyses. MAIN OUTCOMES AND MEASURES Pulmonary function, exocrine pancreatic insufficiency (PI), and CF-related diabetes (CFRD) were investigated as primary outcomes. Odds ratios (ORs) or weighted mean differences (WMDs) with 95% CIs were calculated. The hypothesis was formulated before data collection. RESULTS Of 10 524 records identified, 61 met the selection criteria and were included in the qualitative analysis. Of these, 17 studies were included in the quantitative synthesis. Altogether, 9114 patients were included in the systematic review and meta-analysis. Overweight (WMD, -8.36%; 95% CI, -12.74% to -3.97%) and obesity (WMD, -12.06%; 95% CI, -23.91% to -0.22%) were associated with higher forced expiratory volume in the first second of expiration compared with normal weight. The odds for CFRD and PI were more likely in patients of normal weight (OR, 1.49; 95% CI, 1.10 to 2.00) than in those who were overweight (OR, 4.40; 95% CI, 3.00 to 6.45). High heterogeneity was shown in the analysis of pulmonary function (I2 = 46.7%-85.9%). CONCLUSIONS AND RELEVANCE The findings of this systematic review and meta-analysis suggest that the currently recommended target BMI in patients with CF should be reconsidered. Studies with long-term follow-up are necessary to assess the possible adverse effects of higher BMI or higher fat mass in patients with CF.

Abstract
AIM Room service is a patient-focused foodservice model gaining interest in Australian hospitals following demonstrated patient and organisational benefits. This study aimed to compare nutritional intake, waste, patient satisfaction, meal costs and meal quality between a bought-in, thaw-retherm foodservice model and a cook-fresh, on-demand room service model at a large tertiary public hospital. METHODS A retrospective analysis of quality assurance data compared thaw-retherm to room service. Nutritional intake and plate waste were measured using a visual intake analysis tool; production waste was measured using weighted analysis methodology; patient satisfaction was measured using a validated patient satisfaction survey; meal quality was assessed using a validated meal quality audit tool, and meal costs were obtained from hospital finance reports. Independent sample t-tests or nonparametric equivalent (Mann-Whitney U-test) for continuous variables and Pearson's Chi-square for categorical data were applied for comparative purposes. RESULTS Average energy and protein intake, as well as percentage requirements met, improved between thaw-retherm and room service (4320 kJ/day vs 7265 kJ/day; 42.4 g/day vs 82.5 g/day; and 46% vs 80.7%; 49.9% vs 98.4%; all P < .001. Reductions in plate waste (40% vs 15%) and production waste (15% vs 5.6%, P < .001) were observed and food costs decreased by 9% with room service. Meal quality audit results improved, and patient satisfaction increased with % respondents satisfied increasing from 75.0% to 89.8% (χ2 9.985[2]; P = .007) for room service. CONCLUSIONS This research demonstrates significant improvements in patient and organisational outcomes with room service compared to a thaw-retherm model in a large public hospital.

Physiol Rep 2021; 9:e14886. [PMID: 34086412 PMCID: PMC8176904 DOI: 10.14814/phy2.14886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Accepted: 05/02/2021] [Indexed: 11/24/2022] Open
Abstract
Cystic fibrosis (CF) is a life‐limiting autosomal recessive genetic disease caused by variants in the CFTR gene, most commonly by the [F508del] variant. Although CF is a classical Mendelian disease, genetic variants in several modifier genes have been associated with variation of the clinical phenotype for pulmonary and gastrointestinal function and urogenital development. We hypothesized that whole genome sequencing of a well‐phenotyped CF populations might identify novel variants in known, or hitherto unknown, modifier genes. Whole genome sequencing was performed on the Illumina HiSeq X platform for 98 clinically diagnosed cystic fibrosis patient samples from the Adult CF Clinic at the University of California San Diego (UCSD). We compared protein‐coding, non‐silent variants genome wide between CFTR [F508del] homozygotes vs CFTR compound heterozygotes. Based on a single variant score test, we found 3 SNPs in common variants (MAF >5%) that occurred at significantly different rates between homozygous [F508del]CFTR and compound heterozygous [F508del]CFTR patients. The 3 SNPs were all located in one gene on chromosome 2: Tensin 1 (TNS1: rs3796028; rs2571445: and rs918949). We observed significantly lower BMIs in homozygous [F508del]CFTR patients who were also homozygous for Tensin 1 rs918949 (T/T) (p = 0.023) or rs2571445 (G/G) (p = 0.02) variants. The Tensin 1 gene is thus a potential modifier gene for low BMI in CF patients homozygous for the [F508del]CFTR variant.

DeltaF508 CFTR Hetero- and Homozygous Paediatric Patients with Cystic Fibrosis Do Not Differ with Regard to Nutritional Status. Nutrients 2021; 13:nu13051402. [PMID: 33919435 PMCID: PMC8143312 DOI: 10.3390/nu13051402] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 04/03/2021] [Accepted: 04/19/2021] [Indexed: 12/30/2022] Open
Abstract
The purpose of this study was to compare the nutritional status between deltaF508 CFTR hetero- and homozygous paediatric patients with cystic fibrosis. We assessed the percentage profiles of fatty acids measured in erythrocyte membranes and the serum levels of vitamins A, D3, E and K1 in the studied groups. We also measured the weights and heights and calculated the body mass indexes (BMIs). The studied groups consisted of 34 heterozygous and 30 homozygous patients. No statistically significant differences were found in the serum vitamins or erythrocyte membrane fatty acid profiles between the hetero- and homozygous patient groups, except for heptadecanoic acid (p = 0.038). The mean percentiles of height, weight and BMI did not differ significantly between the two groups. The homozygous and heterozygous paediatric patients with cystic fibrosis were similar in terms of their nutritional statuses.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is associated with accelerated decline in lung health in children with cystic fibrosis (CF). Thus, antireflux surgery (ARS) is offered to a selected CF cohort with refractory GERD, but outcomes remain poorly investigated. This study aimed to determine the incidence of GERD in children with CF and to evaluate complications and outcomes of ARS. MATERIALS AND METHODS A systematic literature-based search was conducted using various online databases according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The number of GERD cases in pediatric CF cohorts who underwent diagnostic investigation(s) was recorded. Data on postoperative complications and outcomes (including symptoms, lung function, and nutritional status) following ARS were analyzed. RESULTS Ten articles (n = 289 patients) met the defined inclusion criteria (51% male; age range, 0.5 month-36 years). The overall incidence of GERD was 46% (range, 19-81%), derived from seven studies (n = 212 patients). Four publications (n = 82 patients) reported on ARS due to uncontrolled GERD. All ARSs were Nissen fundoplication (majority with gastrostomy placement). Major postoperative complications occurred in 15 (18%) patients, two required redo-ARS. Median follow-up time was 2 years (range, 3 months-6 years); 59% showed symptom improvement, and pulmonary exacerbations and decline in lung function were reduced. Nutritional status mainly improved in milder CF cases. There were no deaths related to ARS. CONCLUSION Approximately half of pediatric CF patients have GERD. Published data for children with CF are limited and heterogeneous in terms of GERD diagnosis and outcomes following ARS. However, ARS has shown to slow the deterioration of lung function in CF.

Triage for Malnutrition Risk among Pediatric and Adolescent Outpatients with Cystic Fibrosis, Using a Disease-Specific Tool. CHILDREN 2020; 7:children7120269. [PMID: 33291524 PMCID: PMC7761802 DOI: 10.3390/children7120269] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 11/26/2020] [Accepted: 12/01/2020] [Indexed: 01/01/2023]
Abstract
Malnutrition prevails in considerable proportions of children with Cystic Fibrosis (CF), and is often associated with adverse outcomes. For this, routine screening for malnutrition is pivotal. In the present cross-sectional study, we aimed to assess the risk for malnutrition in pediatric outpatients with CF. A total of 76 outpatients (44 girls, 11.9 ± 3.9 years old, 39.5% adolescents) were recruited and anthropometric, clinical, dietary and respiratory measures were collected. All outpatients were screened for malnutrition risk with a validated disease-specific instrument. Most children exhibited a low risk for malnutrition (78.9%), whereas none of the participants were characterized as having a high malnutrition risk. In the total sample, malnutrition risk was positively associated with age (r = 0.369, p = 0.001), and inversely related to the body mass index (r = −0.684, p < 0.001), height z-score (r = −0.264, p = 0.021), and forced expiratory volume (FEV1%, r = −0.616, p < 0.001). Those classified as having a low malnutrition risk were younger (p = 0.004), heavier (p < 0.001) and taller (p = 0.009) than their counterparts with a moderate risk. On the other hand, patients in the moderate risk group were more likely pubertal (p = 0.034), with a reduced mid-upper arm fat area (p = 0.011), and worse pulmonary function (p < 0.001). Interestingly, none of the children attaining ideal body weight were classified as having a moderate malnutrition. risk, whereas 37.5% of the patients allocated at the moderate risk group exhibited physiological lung function. In this cohort of outpatients with CF that were predominantly well-nourished and attained physiological lung function, malnutrition risk was identified only in small proportions of the sample. Our data support that patients that are older, pubertal, or have diminished fat mass are at greater risk for malnutrition.

Long-term use of tube feeding in children with cystic fibrosis: results from two Belgian CF centers. Eur J Clin Nutr 2020; 75:620-627. [PMID: 33077878 DOI: 10.1038/s41430-020-00782-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 09/21/2020] [Accepted: 10/08/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND Enteral tube feeding (ETF) is often used in an attempt to optimize the nutritional status. The aim of this study was to observe the long term effect of ETF and to compare the start of ETF with the current European guidelines on nutrition care in CF. METHOD From all patients who received ETF (ETFp) between February 2000 and September 2016 in the Ghent University Hospital (GUH) or Brussels University Hospital (BUH), z-scores for body weight (W), height (H), growth velocity (GV) and BMI, FEV1%, and FVC% were retrospectively collected from the patients' medical record, 3 years before and 5 years after the year of ETF initiation. Gender, age, and pancreatic status matched controls were selected from the GUH database. RESULTS All baseline (T0) measurements in ETFp were worse compared to controls. Only 11% of the controls had a Hz < -1.6 compared 58% of the ETFp. After the initiation of ETF a rapid weight gain was noted until the second year (T + 2:-1.9 (-2.8; -1.0) vs. T0:-2.7 (-3.2; -2.1) (p = 0.01) with a stabilization afterwards. A rapid GVz increase was noted at T + 1:1.0 (-0.8; 1.9) vs. T0:-1.5 (-2.0;-0.3). After the start of ETF until T + 3, a stabilization of FEV1% was noted. However, compared to controls, it remained significantly lower (p < 0.05). CONCLUSION ETF as a nutritional intervention has its effect on weight, height, GV, and BMI. To our knowledge this is the first study that describes the evolution of growth in ETFp. The effect on GV argues for a faster introduction of ETF in malnourished children with CF.

Abstract
Abstract
The study aimed to assess: (1) differences in nutritional status and lung function between CF patients and the control group; (2) differences in body composition and lung function between groups of patients with CF designated by type of mutation; (3) the relationship between lung function and body composition in CF patients.
We studied 37 CF patients aged 19 to 51 years, and 41 healthy non-CF volunteers. Nutritional status was evaluated based on the BMI and the bioelectrical impedance analysis. The lung function was described by FEV1%. CF patients were classified according to the CFTR genotype based on five classes of mutations. BMI were lower in CF patients compared to reference group (women: Z = 3.76, p <0.001, men: Z = 3.06, p = 0.002). CF patients had a lower mean content of particular body components, as well as FEV1% values. BMI differed significantly depending on the type of mutation in females (H = 10.33, p = 0.006) and males (H = 8.26, p = 0.016). The lowest values of BMI were observed in the group of patients with severe types of mutations. Also, variables describing body composition were statistically significantly lower in patients with a severe type of mutations. The CFTR gene mutation type statistically significantly differentiated FEV1% (H = 23.22, p <0.000). The results of the logistic regression analysis showed that the likelihood of dropping FEV1% below the norm was twice as high in undernourished females and males. To assess the nutritional status of CF patients, more informative methods describing the proportions of body components are required.

Abstract
OBJECTIVES Forced expiratory volume in 1 second (FEV1) is an important predictor of outcome in cystic fibrosis (CF). This study aimed to describe the change in lung function, nutritional status, and mortality of children with CF at a single center in Cape Town, South Africa, and identify factors associated with poor lung function and mortality. METHODS A retrospective study was conducted of children aged between 5 and 18 years between January 2007 and December 2016. At least two separate best annual FEV1 measurements were required for inclusion in the study. RESULTS A total of 143 children were followed up from which 107 study participants (median diagnosis age 5.5 months) were included. There was no statistically significant improvement from 2007 to 2016 in population mean FEV1 (2.5 ± 1.70 to -1.9 ± 1.70 [P = .1]) and body mass index (-0.7 ± 1.2 to -0.4 ± 1.2 [P = .3]) Z scores. FEV1 Z score declined by 0.17 per year. No significant correlation between FEV1 and age of diagnosis, sex, ethnicity, genotype, geographical location, pancreatic status, or infections was identified. On multiple stepwise regression analysis, FEV1 at age 6 was found to be the only independent predictor of mortality (adjusted odds ratio [95% CI] 0.5 [0.3-0.8]; P = .005). CONCLUSION FEV1 at age 6 was an independent predictor for CF-related mortality. Measurement of lung function in preschool children in SA with CF using more sensitive methods than spirometry is important to identify children at risk of poor outcomes.

Underweight Patients With Cystic Fibrosis Have Acceptable Survival Following Lung Transplantation: A United Network for Organ Sharing Registry Study. Chest 2020; 157:898-906.

Abstract
BACKGROUND Reduced BMI is an absolute contraindication for lung transplantation (LTx) at most centers in the United States. The objective of this study was to quantify post-LTx survival of moderate to severely underweight patients with cystic fibrosis (CF) (BMI < 17 kg/m2) in the United States relative to normal-weight recipients with CF and other frequently transplanted patient cohorts. METHODS Using United Network for Organ Sharing Registry data (undergoing transplant from June 2005-November 2015), Kaplan-Meier estimates of median posttransplant survival were calculated for all patients with CF, COPD, and idiopathic pulmonary fibrosis (IPF), as well as low and normal weight CF subgroups. Cox regression modeling stratified according to transplant center assessed risk of posttransplant mortality in recipients with CF and a BMI < 17 kg/m2 compared with recipients with COPD (reference). RESULTS Median posttransplant survival (95% CI) for CF, COPD, and IPF was 7.9 (7.2-8.6), 5.9 (5.6-6.2), and 5.5 (5.2-5.8) years, respectively. Although an absolute decrease was noted in posttransplant survival for recipients with CF and a BMI < 17 kg/m2, compared with those with CF and a BMI ≥ 17 kg/m2 (7.0 years [4.5-7.9] vs 8.2 years [7.3-9.0]), Cox modeling found no increased mortality risk (adjusted hazard ratio, 1.09; 95% CI, 0.90-1.32; P = .38). There was no difference in posttransplant mortality between patients with CF and a BMI < 17 kg/m2 and recipients with COPD and all BMIs (adjusted hazard ratio, 1.04; 95% CI, 0.86-1.25; P = .71). CONCLUSIONS Transplant recipients with CF and a BMI < 17 kg/m2 had posttransplant survival rates comparable to those of other groups frequently undergoing transplantation. BMI < 17 kg/m2 as a single risk factor in the CF population should not be treated as an absolute contraindication to LTx.

Abstract
Cystic fibrosis (CF), a severe life-limiting disease, is associated with multi-organ pathologies that contribute to a reduced exercise capacity. At present, the impact of, and interaction between, disease progression and other age-related physiological changes in CF on exercise capacity from child- to adult-hood is poorly understood. Indeed, the influences of disease progression and aging are inherently linked, leading to increasingly complex interactions. Thus, when interpreting age-related differences in exercise tolerance and devising exercise-based therapies for those with CF, it is critical to consider age-specific factors. Specifically, changes in lung function, chronic airway colonization by increasingly pathogenic and drug-resistant bacteria, the frequency and severity of pulmonary exacerbations, endocrine comorbidities, nutrition-related factors, and CFTR (cystic fibrosis transmembrane conductance regulator protein) modulator therapy, duration, and age of onset are important to consider. Accounting for how these factors ultimately influence the ability to exercise is central to understanding exercise impairments in individuals with CF, especially as the expected lifespan with CF continues to increase with advancements in therapies. Further studies are required that account for these factors and the changing landscape of CF in order to better understand how the evolution of CF disease impacts exercise (in)tolerance across the lifespan and thereby identify appropriate intervention targets and strategies.

Abstract
CASE DETAILS A 19-year-old girl presented to the emergency department following overdose of 10 g of paracetamol on a background history of cystic fibrosis. Paracetamol concentration was below the nomogram line, but was treated with acetylcysteine seven hours post-overdose given her symptomatology. Nineteen hours following her overdose she developed hepatotoxicity, despite early initiation of acetylcysteine. She was discharged well six days post-ingestion. On presentation, delta miRNA-122-miR483 was 20 times that of control patients, however, alanine aminotransferase was normal. DISCUSSION Patients with cystic fibrosis are more likely to have glutathione deficiency, and greater susceptibility to liver injury. Delta miRNA may be a better detector of early liver injury than hepatic aminotransferases. Empiric treatment with acetylcysteine and serial biochemical reassessment in this setting should be considered.

Abstract
Objective: To evaluate the association between nutritional status, lung function and
morbidity in a 36-month cohort in children and adolescents with cystic
fibrosis. Methods: Prospective cohort of children and adolescents with cystic fibrosis aged 1-15
years. At the baseline, the nutritional status was determined by weight-for-height
and body mass index-for-age for children <2 years and ≥2 years, respectively,
and classified as: nutritional failure, nutritional risk and acceptable; and by
the 50th percentile, according to the World Health Organization (WHO) growth
charts. Lung function was assessed by forced expiratory volume in one second
(FEV1). Morbidity was determined by the presence of infection and hospitalization
by pulmonary exacerbation. Risk ratio and 95% confidence interval (95%CI) were
calculated, being significant when p<0.05. Results: We evaluated 38 children and adolescents (median age 3.8 years). Patients that
were classified as having nutritional failure at baseline had a RR of 5.00 (95%CI
1.49; 16.76) to present impaired lung function after 36 months. Those classified
bellow the 50th percentile had a RR of 4.61 (95%CI 0.89; 23.81) to present the
same outcome. Nutritional status was not a risk factor for morbidity in this
cohort. Conclusions: Nutritional deficit was associated with impaired lung function, but not with
morbidity in children and adolescents with cystic fibrosis.

INTRODUCTION In 2015, the Australasian Pancreatic Club (APC) published the Australasian guidelines for the management of pancreatic exocrine insufficiency (http://pancreas.org.au/2016/01/pancreatic-exocrine-insufficiency-guidelines). Pancreatic exocrine insufficiency (PEI) occurs when normal digestion cannot be sustained due to insufficient pancreatic digestive enzyme activity. This may be related to a breakdown, at any point, in the pancreatic digestive chain: pancreatic stimulation; synthesis, release or transportation of pancreatic enzymes; or synchronisation of secretions to mix with ingested food. Main recommendations: The guidelines provide advice on diagnosis and management of PEI, noting the following: A high prevalence of PEI is seen in certain diseases and conditions, such as cystic fibrosis, acute and chronic pancreatitis, pancreatic cancer and pancreatic surgery. The main symptoms of PEI are steatorrhoea or diarrhoea, abdominal pain, bloating and weight loss. These symptoms are non-specific and often go undetected and untreated. PEI diagnosis is predominantly based on clinical findings and the presence of underlying disease. The likelihood of PEI in suspected patients has been categorised into three groups: definite, possible and unlikely. If left untreated, PEI may lead to complications related to fat malabsorption and malnutrition, and have an impact on quality of life. Pancreatic enzyme replacement therapy (PERT) remains the mainstay of PEI treatment with the recommended adult initial enzyme dose being 25 000-40 000 units of lipase per meal, titrating up to a maximum of 75 000-80 000 units of lipase per meal. Adjunct acid-suppressing therapy may be useful when patients still experience symptoms of PEI on high dose PERT. Nutritional management by an experienced dietitian is essential. Changes in management as a result of these guidelines: These are the first guidelines to classify PEI as being definite, possible or unlikely, and provide a diagnostic algorithm to facilitate the early diagnosis of PEI and appropriate use of PERT.

Abstract
The aim of the present study is to evaluate of the impact of immunonutrition on parameters of oxidative stress and inflammation in patients with cystic fibrosis and malnutrition. In the 30 patients with cystic fibrosis and long-term enteral nutrition support for malnutrition the effect of standard and immunonutrion sipping on oxidative stress and inflammatory activity parameters was compared. Malonyldialdehyde (MDA) as parameter of oxidative stress and serum amyloid A (SAA), interleukin 1 and 6, hsCRP, IgM, IgA, IgG as parameters of inflammatory activity were examined. Immunonutrition decreased SAA to 17.6 mg/L comparing to 25.6 mg/L when standard nutrition was given (p = 0.014). MDA was 0.66 µM on standard and 0.96 µM on immunonutrition support (p<0.01). The significant negative correlation was recorded between MDA and SAA, hs-CRP, interleukin 6, IgA and IgG. In conclusion, the application of immunonutrition in patients with cystic fibrosis and malnutrition is associated with drop of SAA but with the rise of MDA.

Abstract
Nutrition therapy is vital to the overall management of lung transplant recipients. The objective of this review is to outline the current applications of pre- and posttransplant nutrition management of the adult lung transplant recipient. Pretransplant nutrition therapy decisions are based on cause of end-stage lung disease, transplant indications, and pretransplant nutritional status. Maintaining adequate nutrient stores is the major goal of nutrition therapy for patients awaiting transplantation. In the posttransplant course, several gastrointestinal (GI) complications such as gastroesophageal reflux, gastroparesis, and distal intestinal obstruction syndrome complicate nutritional recovery. Long-term nutrition therapy for lung transplant recipients is aimed at management of common comorbid conditions such as obesity, diabetes mellitus, hypertension, osteoporosis, and hyperlipidemia. Lung transplantation outcomes are steadily improving; however, much has yet to be explored to improve the nutrition management of these patients in both the pre- and posttransplantation course.

Abstract
The purpose of the study was to evaluate the influence of nutrition and of the severity of mutation type on survival rate in cystic fibrosis (CF) patients. Data were longitudinally collected from 60 hospitalized adult CF patients, aged 18-50. The variables consisted of body mass index (BMI) ratio, Cole's BMI cut-off points, severity of mutation type, and survival rate of CF patients. We found that the mean BMI was strongly associated with the severity of mutation type and was significantly lower in patients with severe mutations of grade I and II. The mutation type significantly affected the patients' survival rate; survival was greater in patients with mild and undefined mutation types. The BMI and Cole's cut-off points also had a significant influence on survival rate. CF patients, who suffered from malnutrition and emaciation, had a shorter survival rate than those with proper nutritional status. In conclusion, the study findings confirmed a significant effect of nutritional status and of mutation type on survival rate of CF patients.

Abstract
Nutrition is integral to the care of individuals with cystic fibrosis (CF). Better nutritional status is associated with improved pulmonary function. In some individuals with CF, enteral tube feeding can be useful in achieving optimal nutritional status. Current nutrition guidelines do not include detailed recommendations for enteral tube feeding. The Cystic Fibrosis Foundation convened an expert panel to develop enteral tube feeding recommendations based on a systematic review of the evidence and expert opinion. These guidelines address when to consider enteral tube feeding, assessment of confounding causes of poor nutrition in CF, preparation of the patient for placement of the enteral feeding tube, management of the tube after placement and education about enteral feeding. These recommendations are intended to guide the CF care team, individuals with CF, and their families through the enteral tube feeding process.

Abstract
Ataxia telangiectasia (A-T) is a rare, progressive, multisystem disease that has a large number of complex and diverse manifestations which vary with age. Patients with A-T die prematurely with the leading causes of death being respiratory diseases and cancer. Respiratory manifestations include immune dysfunction leading to recurrent upper and lower respiratory infections; aspiration resulting from dysfunctional swallowing due to neurodegenerative deficits; inefficient cough; and interstitial lung disease/pulmonary fibrosis. Malnutrition is a significant comorbidity. The increased radiosensitivity and increased risk of cancer should be borne in mind when requesting radiological investigations. Aggressive proactive monitoring and treatment of these various aspects of lung disease under multidisciplinary expertise in the experience of national multidisciplinary clinics internationally forms the basis of this statement on the management of lung disease in A-T. Neurological management is outwith the scope of this document.

Abstract
Background Previous studies have suggested the existence of enteropathy in cystic fibrosis (CF), which may contribute to intestinal function impairment, a poor nutritional status and decline in lung function. This study evaluated enterocyte damage and intestinal inflammation in CF and studied its associations with nutritional status, CF-related morbidities such as impaired lung function and diabetes, and medication use. Methods Sixty-eight CF patients and 107 controls were studied. Levels of serum intestinal-fatty acid binding protein (I-FABP), a specific marker for enterocyte damage, were retrospectively determined. The faecal intestinal inflammation marker calprotectin was prospectively studied. Nutritional status, lung function (FEV1), exocrine pancreatic insufficiency (EPI), CF-related diabetes (CFRD) and use of proton pump inhibitors (PPI) were obtained from the medical charts. Results Serum I-FABP levels were elevated in CF patients as compared with controls (p<0.001), and correlated negatively with FEV1 predicted value in children (r-.734, p<0.05). Faecal calprotectin level was elevated in 93% of CF patients, and correlated negatively with FEV1 predicted value in adults (r-.484, p<0.05). No correlation was found between calprotectin levels in faeces and sputum. Faecal calprotectin level was significantly associated with the presence of CFRD, EPI, and PPI use. Conclusion This study demonstrated enterocyte damage and intestinal inflammation in CF patients, and provides evidence for an inverse correlation between enteropathy and lung function. The presented associations of enteropathy with important CF-related morbidities further emphasize the clinical relevance.

Abstract
AIM The association between nutritional status, pulmonary function and survival in cystic fibrosis (CF) is well established. A previous case series from the Royal Children's Hospital, Melbourne (RCH), demonstrated suboptimal referral practices and highlighted the importance of early nutritional interventions in children with CF. Various qualitative changes were made to our CF service, and this study assesses the effects of these practice changes timing of gastrostomy and clinical outcome in patients who underwent gastrostomy insertion. METHOD Clinical audit of all CF patients who had undergone gastrostomy insertion from 2002 to 2010 at Royal Children's Hospital. Clinical data, including nutritional parameters, respiratory function and survival, were collected at 2 years prior and 2 years post gastrostomy insertion. Data were compared with the previous study from 1989 to 1997. RESULTS Patients with CF who underwent gastrostomy insertion between 2002 and 2010 (n = 22) had higher weight-for-age scores (-1.5 ± 0.68 vs. -2.67 ± 1.06; P = 0.0001) and higher forced expiratory volume in 1 s (68% ± 22 vs. 52% ± 18.5; P = 0.006), compared with the cohort from 1989 to 1997 (n = 37). These differences were maintained at 2-year follow-up. Pseudomonas aeruginosa colonisation rate was 100% in 1989-1997 vs. 41% in 2002-2010; P = 0.0001. The 2-year survival post-gastrostomy insertion improved from 70% to 100%; P = 0.004. CONCLUSION Earlier referral of patients in the recent cohort resulted in sustained improvements in weight-for-age and lung function. Survival at 2 years post-procedure was significantly improved. This study confirms the value of clinical audits and subsequent re-evaluation of clinical services.

Abstract
Cystic fibrosis (CF) is a lethal, monogenic disorder that affects multiple organ systems of the body. The incidence has been described before in the Middle East to be 1 in 2000 to 1 in 5800 live births, and the median survival was estimated to be from 10 to 20 years of age. The present article attempts to revisit various facets of this disease and specifically highlights the most important lacunae that exist in treating CF. In addition, it also tries to emphasize the steps in improving the median survival of patients with CF, in these countries.

Monitoring changes in plasma levels of pancreatic and intestinal enzymes in a model of pancreatic exocrine insufficiency--induced by pancreatic duct-ligation--in young pigs.

Abstract
PURPOSE Plasma levels of pancreatic and intestinal enzymes were measured after pancreatic duct ligation (PDL) to monitor pancreatic exocrine insufficiency (PEI) in a model using young pigs. MATERIAL/METHODS Five, 6 week-old pigs (10.9±0.2kg), underwent PDL while age-matched, un-operated pigs were used as controls. Plasma levels of immunoreactive cationic trypsinogen (IRCT), amylase, lipase, and diamine oxidase (DAO) activities were analyzed for 48 days after PDL, including 1 week of oral pancreatic enzyme supplementation (PES) with Creon(®). RESULTS PDL resulted in an arrested body growth and a rapid surge of pancreatic enzymes (IRCT, amylase and lipase) into the plasma. Nine days after PDL, the plasma levels of these pancreatic enzymes had decreased. IRCT then remained below the level in un-operated pigs while amylase only fell below control at 25 days. The intestinally derived marker DAO and plasma protein levels were unaffected by PDL but DAO decreased slightly with time in PEI pigs. One-week of oral PES restored body growth, but had little effect on pancreatic enzyme plasma levels, except for a tendency towards increased DAO. CONCLUSIONS The study showed that PEI developed within 1-2 weeks after PDL and that only IRCT is a reliable plasma enzyme marker for this. The reduced plasma DAO indicated that PEI also affected the intestines, while PES therapy restored growth of the PDL pigs and slightly increased plasma DAO, suggesting an improved intestinal function.

Abstract
Cystic fibrosis can affect food digestion and nutrient absorption. The underlying mutation of the cystic fibrosis trans-membrane regulator gene depletes functional cystic fibrosis trans-membrane regulator on the surface of epithelial cells lining the digestive tract and associated organs, where Cl(-) secretion and subsequently secretion of water and other ions are impaired. This alters pH and dehydrates secretions that precipitate and obstruct the lumen, causing inflammation and the eventual degradation of the pancreas, liver, gallbladder and intestine. Associated conditions include exocrine pancreatic insufficiency, impaired bicarbonate and bile acid secretion and aberrant mucus formation, commonly leading to maldigestion and malabsorption, particularly of fat and fat-soluble vitamins. Pancreatic enzyme replacement therapy is used to address this insufficiency. The susceptibility of pancreatic lipase to acidic and enzymatic inactivation and decreased bile availability often impedes its efficacy. Brush border digestive enzyme activity and intestinal uptake of certain disaccharides and amino acids await clarification. Other complications that may contribute to maldigestion/malabsorption include small intestine bacterial overgrowth, enteric circular muscle dysfunction, abnormal intestinal mucus, and intestinal inflammation. However, there is some evidence that gastric digestive enzymes, colonic microflora, correction of fatty acid abnormalities using dietary n-3 polyunsaturated fatty acid supplementation and emerging intestinal biomarkers can complement nutrition management in cystic fibrosis.

Abstract
RATIONALE Several extrapulmonary disorders have been linked to cigarette smoking. Smoking is reported to cause cystic fibrosis transmembrane conductance regulator (CFTR) dysfunction in the airway, and is also associated with pancreatitis, male infertility, and cachexia, features characteristic of cystic fibrosis and suggestive of an etiological role for CFTR. OBJECTIVES To study the effect of cigarette smoke on extrapulmonary CFTR function. METHODS Demographics, spirometry, exercise tolerance, symptom questionnaires, CFTR genetics, and sweat chloride analysis were obtained in smokers with and without chronic obstructive pulmonary disease (COPD). CFTR activity was measured by nasal potential difference in mice and by Ussing chamber electrophysiology in vitro. Serum acrolein levels were estimated with mass spectroscopy. MEASUREMENTS AND MAIN RESULTS Healthy smokers (29.45 ± 13.90 mEq), smokers with COPD (31.89 ± 13.9 mEq), and former smokers with COPD (25.07 ± 10.92 mEq) had elevated sweat chloride levels compared with normal control subjects (14.5 ± 7.77 mEq), indicating reduced CFTR activity in a nonrespiratory organ. Intestinal current measurements also demonstrated a 65% decrease in CFTR function in smokers compared with never smokers. CFTR activity was decreased by 68% in normal human bronchial epithelial cells exposed to plasma from smokers, suggesting that one or more circulating agents could confer CFTR dysfunction. Cigarette smoke-exposed mice had decreased CFTR activity in intestinal epithelium (84.3 and 45%, after 5 and 17 wk, respectively). Acrolein, a component of cigarette smoke, was higher in smokers, blocked CFTR by inhibiting channel gating, and was attenuated by antioxidant N-acetylcysteine, a known scavenger of acrolein. CONCLUSIONS Smoking causes systemic CFTR dysfunction. Acrolein present in cigarette smoke mediates CFTR defects in extrapulmonary tissues in smokers.

Abstract
BACKGROUND Optimal nutritional status (NS) in cystic fibrosis (CF) is associated with better lung function and increased overall survival. This study estimated the prevalence of malnutrition and obesity among CF patients in a tertiary center. METHODS In a cross-sectional study of 68 CF patients (33 female; 37 children/adolescents) weight, height, body composition, respiratory function (% of the predicted forced expiratory volume in 1 s; FEV1%pred ) and serum lipids were measured; body mass index (BMI), BMI standard deviation score (BMI-SDS) and BMI percentiles were calculated; Pseudomonas colonization, pancreatic insufficiency, diabetes mellitus (CFDM), liver disease (CFLD) and genotype were recorded; NS was classified according to the 2005 Cystic Fibrosis Foundation (CFF) criteria. Frequency distributions and associations between anthropometric and clinical parameters (univariate/multivariate) were calculated. RESULTS Mean age (±SD) was 19.81 ± 8.98 years. Regarding NS: 22.1% were malnourished, 13.2% overweight/obese and 29.4% had optimal NS. Pancreatic function (PF), Pseudomonas colonization, CFDM, CFLD and genotype differed significantly among the three groups. FEV1%pred was significantly higher among overweight/obese patients and correlated positively with anthropometric characteristics as well as serum cholesterol and negatively with age. BMI-SDS was associated with PF, FEV1%pred and CFDM. Among overweight/obese patients 89.9% had adequate PF and 66.7% carried mutations other than F508del. No patient had any traits of metabolic syndrome. CONCLUSIONS Despite appropriate management only one-third of the present patients had optimal NS. One-fourth were malnourished and a significant percentage were overweight/obese. The latter were mostly carriers of mutations other than F508del and had better pulmonary function. CF patients require intensive monitoring for both malnutrition and overweight/obesity.

Abstract
RATIONALE Ivacaftor (VX-770), a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, has been shown to improve lung function, pulmonary exacerbation rate, respiratory symptoms, and weight gain compared with placebo in patients with cystic fibrosis aged 12 years or older with a G551D-CFTR mutation. OBJECTIVES This randomized, double-blind, placebo-controlled trial evaluated ivacaftor in patients with cystic fibrosis aged 6-11 years with a G551D-CFTR mutation on at least one allele. METHODS Patients were randomly assigned to receive ivacaftor administered orally at 150 mg (n = 26) or placebo (n = 26) every 12 hours for 48 weeks in addition to existing prescribed cystic fibrosis therapies. MEASUREMENTS AND MAIN RESULTS Despite near-normal mean baseline values in FEV1, patients receiving ivacaftor had a significant increase in percent predicted FEV1 from baseline through Week 24 versus placebo group (treatment effect, 12.5 percentage points; P < 0.001). Effects on pulmonary function were evident by 2 weeks, and a significant treatment effect was maintained through Week 48. Patients treated with ivacaftor gained, on average, 2.8 kg more than those receiving placebo at Week 48 (P < 0.001). The change from baseline through Week 48 in the concentration of sweat chloride, a measure of CFTR activity, with ivacaftor was -53.5 mmol/L (P < 0.001) versus placebo. The incidence of adverse events was similar in the two groups. CONCLUSIONS In patients who are younger and healthier than those in previously studied populations, ivacaftor demonstrated a significant improvement in pulmonary function, weight, and CFTR activity compared with placebo. Clinical trial registered with www.clinicaltrials.gov (NCT00909727).

Abstract
Poor clinical outcomes in cystic fibrosis are often associated with undernutrition. Normal growth and development should be achieved in cystic fibrosis, and nutritional counseling is paramount at all ages. Prevention and early detection of growth failure is the key to successful nutritional intervention. The advance in nutritional management is certainly one factor that has contributed to the improved survival in recent decades. This review outlines the major nutritional parameters in the management of the patient with cystic fibrosis, including recent advances in pancreatic enzyme replacement therapy and fat-soluble vitamin therapy. There are sections on complicated clinical situations which directly affect nutrition, for example, before and after lung transplantation, cystic fibrosis-related diabetes, and bone health.

Abstract
OBJETIVO: Revisar e discutir evidências sobre a avaliação do estado nutricional e as recomendações para o tratamento nutricional de crianças e adolescentes com fibrose cística. FONTES DE DADOS: Bancos de dados MEDLINE (versão PubMed) e Latin American and Caribbean Center on Health Sciences Information (LILACS), entre 1984 a 2009. Aplicou-se a combinação dos seguintes descritores: fibrose cística, estado nutricional, criança e adolescente - em inglês e português. SÍNTESE DOS DADOS: A fibrose cística é uma doença genética, de evolução crônica, progressiva e fatal. Resulta do defeito na proteína reguladora transmembrana que regula a condução de cloro e, consequentemente, o fluxo de sódio e água através da membrana apical das células epiteliais. Pacientes fibrocísticos são vulneráveis à desnutrição, que resulta do desequilíbrio entre ingestão alimentar, gasto e perdas energéticas. Novos conhecimentos sobre a fisiopatologia da doença, adquiridos nas últimas décadas, resultaram em mudanças significativas nas atuais recomendações energéticas e principalmente de lipídeos. A importância da nutrição no bem-estar e sobrevida dos fibrocísticos está bem estabelecida, assim como a associação entre a desnutrição e a deterioração da função pulmonar. Existem múltiplos fatores inter-relacionados que afetam o estado nutricional, tais como, mutação genética, insuficiência pancreática, ressecção intestinal, perda de sais e ácidos biliares, refluxo gastroesofágico, inflamação e infecções pulmonares, diabetes e condições emocionais. CONCLUSÕES: O monitoramento nutricional e o aconselhamento dietético são elementos chave no manejo de crianças e adolescentes com fibrose cística com o intuito de controlar a sintomatologia e a progressão da doença, proporcionando melhor qualidade de vida.

Abstract
BACKGROUND Malnutrition is a well-known complication in cystic fibrosis (CF). There is good evidence that maintaining a normal body-weight correlates well with improved survival in CF. Energy intake in excess of 120% of the estimated average requirement (EAR) has been advised since 1980s. OBJECTIVES To investigate the nutritional intake and status in the adult Scandinavian CF-population. SUBJECTS/METHODS A cross-sectional multi-centre study was used to investigate the nutritional status of 456 adult CF-patients (2003 2006). Height and weight were measured and body mass index (BMI) and z-scores were calculated. Pulmonary function was examined by dynamic spirometry. A 7-day pre-coded food record (FR) obtained energy and nutrient intake data in 180 patients. RESULTS The mean energy intake was 114 (SD 30.0)% of EAR and thus significantly lower than the target of 120% EAR (p< 0.001) for patients with pancreatic insufficiency (PI) (n=136). Mean BMI was 22.0 (SD 2.9), the prevalence of BMI <18 was 13% and the prevalence of BMI ≥25 was 15% (n=136). Mean BMI was 20.8 (SD 2.4) in PI-patients with FEV(1) <70% and 23.2% (SD 3.0), in PI-patients with FEV(1) ≥70%, mean difference 2.4, (95% CI: 1.5, 3.3) (p<0.001), but there was no difference in energy intake. BMI ≥18.5 and a reported energy intake <120% were revealed in 54% of the PI-patients. CONCLUSIONS The energy intake did not reach the recommended 120% EAR, but the prevalence of underweight was lower than reported in other studies. The recommendation may exceed the requirement for a number of CF-patients. The nutritional status must still be closely monitored and nutritional advice and intervention should be individualised and adjusted to actual needs.

Abstract
OBJECTIVES The aim of the study was to assess the efficacy of gastrostomy tube (GT) placement on improving nutritional status and pulmonary function in patients with cystic fibrosis (CF). PATIENTS AND METHODS Data were collected from the Minnesota Cystic Fibrosis Database. Subjects with at least 5 percent-predicted forced expiratory volume in 1 second (ppFEV1) and 1 BMI percentile (pBMI) measurements before and after GT placement were included. Median pBMI values were compared 2 years before and 1, 2, and 4 years after GT placement using a signed rank test. Longitudinal mixed model analysis was used to assess the effect of GT placement on ppFEV1. To assess the effect of ppFEV1 at GT placement on efficacy, the estimated ppFEV1 change was regressed against the ppFEV1 level at placement. RESULTS Forty-six subjects with CF who met entry criteria were identified. Mean estimated step changes in ppFEV1 at placement for men, women, boys, and girls were 2.16% (P = 0.52), 0.43% (P = 0.92), 0.99% (P = 0.65), and -0.91% (P = 0.74), respectively. Mean estimated slope changes of ppFEV1 after GT placement were 5.01% (P = 0.02), 4.48% (P = 0.07), 1.49% (P = 0.23), and 4.02% (P = 0.01) per year for men, women, boys, and girls, respectively. Median change in pBMI in the second year after GT placement was 13.3% (P ≤ 0.0001). Estimated coefficients for the effect of ppFEV1 level at placement on the ppFEV1 step and slope change were -0.041 (P = 0.28) and -0.005 (P = 0.84), respectively. CONCLUSIONS GT placement in patients with CF results in significant improvement in both pBMI and ppFEV1, except in women. The change in lung function after GT placement is not dependent on the level of lung function at placement.

Abstract
Fat malabsorption in pancreatic insufficient cystic fibrosis (CF) patients is classically treated with pancreatic enzyme replacement therapy (PERT). Despite PERT, intestinal fat absorption remains insufficient in most CF patients. Several factors have been suggested to contribute to the persistent fat malabsorption in CF (CFPFM). We reviewed the current insights concerning the proposed causes of CFPFM and the corresponding intervention studies. Most data are obtained from studies in CF patients and CF mice. Based on the reviewed literature, we conclude that alterations in intestinal pH and intestinal mucosal abnormalities are most likely to contribute to CFPFM. The presently available data indicate that acid suppressive drugs and broad spectrum antibiotics could be helpful in individual CF patients for optimizing fat absorption and/or nutritional status.

Abstract
New treatments are needed to improve the health of people with cystic fibrosis (CF). Reducing lung-damaging inflammation is likely to be beneficial, but specific anti-inflammatory targets have not been identified. By combining cellular immunology with a population-based genetic modifier study, we examined TLR5 as an anti-inflammatory target and modifier gene in CF. Using two pairs of human CF and control airway epithelial cells, we demonstrated that the TLR5-flagellin interaction is a major mediator of inflammation following exposure to Pseudomonas aeruginosa. To validate TLR5 as an anti-inflammatory target, we analyzed the disease modifying effects of the TLR5 c.1174C>T single nucleotide polymorphism (rs5744168) in a large cohort of CF patients (n = 2219). rs5744168 encodes a premature stop codon and the T allele is associated with a 45.5-76.3% reduction in flagellin responsiveness (p < 0.0001). To test the hypothesis that reduced TLR5 responsiveness would be associated with improved health in CF patients, we examined the relationship between rs5744168 and two clinical phenotypes: lung function and body weight. Adults with CF carrying the TLR5 premature stop codon (CT or TT genotype) had a higher body mass index than did CF patients homozygous for the fully functional allele (CC genotype) (p = 0.044); however, similar improvements in lung function associated with the T allele were not statistically significant. Although follow-up studies are needed to confirm the impact of TLR5 on nutritional status, this translational research provides evidence that genetic variation in TLR5 resulting in reduced flagellin responsiveness is associated with improved health indicators in adults with CF.
