Abstract
Cystic fibrosis (CF) results in chronic pulmonary infections, inflammation, pancreatic insufficiency, and multiple gastrointestinal manifestations. Malnutrition and poor growth are hallmarks of CF, and strongly associated with poor outcomes. Through newborn screening, many infants can be diagnosed within a few days of life, which allows for early initiation of nutritional counseling and close clinical follow-up. Obstacles to growth for infants with CF start in utero, as newborns with CF can have a lower birth weight than the general population. Improving infant growth has been linked to improved clinical outcomes and survival. It remains a top priority and challenge for caregivers and healthcare teams. An interdisciplinary approach, including registered dietitian and social work support, is essential to optimize health for infants with CF. Remaining barriers to normalcy include deficits in linear growth, lack of accurate nutrition biomarkers, persistence of inequities related to social determinant of health, particularly in the global CF community.

Extracellular vesicles secreted by primary human bronchial epithelial cells reduce Pseudomonas aeruginosa burden and inflammation in cystic fibrosis mouse lung.

Abstract
Cystic fibrosis (CF) results in a reduction in the volume of airway surface liquid, increased accumulation of viscous mucus, persistent antibiotic-resistant lung infections that cause chronic inflammation, and a decline in lung function. More than 50% of adults with CF are chronically colonized by Pseudomonas aeruginosa (P. aeruginosa), the primary reason for morbidity and mortality in people with CF (pwCF). Although highly effective modulator therapy (HEMT) is an important part of disease management in CF, HEMT does not eliminate P. aeruginosa or lung inflammation. Thus, new treatments are required to reduce lung infection and inflammation in CF. In a previous in vitro study, we demonstrated that primary human bronchial epithelial cells (HBECs) secrete extracellular vesicles (EVs) that block the ability of P. aeruginosa to form biofilms by reducing the abundance of several proteins necessary for biofilm formation as well as enhancing the sensitivity of P. aeruginosa to β-lactam antibiotics. In this study, using a CF mouse model of P. aeruginosa infection, we demonstrate that intratracheal administration of EVs secreted by HBEC reduced P. aeruginosa lung burden and several proinflammatory cytokines including IFN-γ, TNF-α, and MIP-1β in bronchoalveolar lavage fluid (BALF), even in the absence of antibiotics. Moreover, EVs decreased neutrophils in BALF. Thus, EVs secreted by HBEC reduce the lung burden of P. aeruginosa, decrease inflammation, and reduce neutrophils in a CF mouse model. These results suggest that HBEC via the secretion of EVs may play an important role in the immune response to P. aeruginosa lung infection.NEW & NOTEWORTHY Our findings show that extracellular vesicles secreted by primary human bronchial epithelial cells significantly reduce Pseudomonas aeruginosa burden, inflammation, and weight loss in a cystic fibrosis mouse model of infection.

Dietary intake, weight status, pulmonary function, and metabolic profile in children with cystic fibrosis with or without pancreatic sufficiency. Nutrition 2023; 114:112091. [PMID: 37356169 DOI: 10.1016/j.nut.2023.112091] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 05/04/2023] [Accepted: 05/19/2023] [Indexed: 06/27/2023]
Abstract
OBJECTIVE Nutritional status and growth is well associated with disease outcomes and lung function in patients with cystic fibrosis (CF). Current dietary guidelines for the management of CF suggest a high-calorie, high-fat diet. Pancreatic insufficiency (PI) is present in most patients and contributes to malabsorption and malnutrition, but a considerable number of patients have pancreatic sufficiency (PS). The aim of this study was to compare weight status, clinical characteristics, and dietary intake of children with CF, with PS or PI. METHODS Patients with a diagnosis of CF (sweat test ≥60 mmol/L) and/or two known mutations for CF, ages 1 to 19 y were included in the study. Weight status, pulmonary characteristics, and blood lipid concentrations were evaluated. Dietary intake was evaluated through four 24-h recalls and energy, macronutrient intake, and intake in terms of food groups were assessed. RESULTS Included in the present analyses were 134 patients with CF (30 with PS and 104 with PI). The percentage of overweight/obesity (47%) was higher in children with PS than in those with PI (22%). Overall, children with PS had higher body mass index, blood lipid levels, and pulmonary function levels than those with PI (all P < 0.05). Total energy intake was lower in children with PS than in those with PI (P < 0.001), even after adjustment for age and sex (Padj < 0.001). CONCLUSIONS Weight status, dietary intake, pulmonary function, and lipid profile differed significantly in children with CF by pancreatic status. Nevertheless, the percentage of overweight and obesity was higher in children with PS than in those with PI. To avoid obesity, dietary recommendations for a high-calorie, high-fat diet should be reconsidered in patients with CF regarding their pancreatic status.

Trajectories of early growth and subsequent lung function in cystic fibrosis: An observational study using UK and Canadian registry data. J Cyst Fibros 2022:S1569-1993(22)00658-0. [PMID: 36088206 DOI: 10.1016/j.jcf.2022.09.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 08/18/2022] [Accepted: 09/01/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Understanding the pulmonary impact of changes in early life nutritional status over time in a paediatric CF population may help inform how to use nutritional assessment to guide clinical care. National registry data provides an opportunity to study patterns of weight gain over time at the level of the individual, and thus to gain detailed understanding of the relationship between early weight trajectories and later lung function in children with Cystic Fibrosis (CF). METHODS Using data from the United Kingdom (UK) and Canadian CF Registries, a mixed effects linear regression model was used to describe children's weight and BMI z-score trajectories from age 1 to 5 years. The intercept (weight-for-age at age 1) and slope (weight-for-age trajectory) from this model were then used as covariates in a linear regression of first lung function measurement at age 6 years. RESULTS In both the UK and Canadian data, greater weight-for-age z-score at age 1 year and greater change in weight-for-age over time were associated with higher FEV1% predicted. A greater weight-for-age z-score at age 1 year was associated with a higher FEV1% predicted (UK: 3.78% (95% CI: 1.76; 4.70); Canada: 3.20% (95%CI: 1.76, 4.70)). These associations were reproduced for BMI z-scores and FVC% predicted. CONCLUSIONS Early weight-for-age, specifically at age 1 year, and weight-for-age trajectories across early childhood are associated with later lung function. This relationship persists after adjustment for potential confounders. Current guidelines may need to be updated to place less emphasis on a specific cut-off (such as the 10th percentile) and encourage tracking of weight-for-age over time.

Abstract
Cystic fibrosis (CF) is a chronic, multisystem disease with multiple comorbidities that can significantly affect nutrition and quality of life. Maintaining nutritional adequacy can be challenging in people with cystic fibrosis and has been directly associated with suboptimal clinical outcomes. Comorbidities of CF can result in significantly decreased nutritional intake and intestinal absorption, as well as increased metabolic demands. It is crucial to utilize a multidisciplinary team with expertise in CF to optimize growth and nutrition, where patients with CF and their loved ones are placed in the center of the care model. Additionally, with the advent of highly effective modulators (HEMs), CF providers have begun to identify previously unrecognized nutritional issues, such as obesity. Here, we will review and summarize commonly encountered comorbidities and their nutritional impact on this unique population.

Abstract
Cystic fibrosis (CF) is a life-shortening genetic disorder that affects the cystic fibrosis transmembrane conductance regulator (CFTR) protein. In the gastrointestinal (GI) tract, CFTR dysfunction results in low intestinal pH, thick and inspissated mucus, a lack of endogenous pancreatic enzymes, and reduced motility. These mechanisms, combined with antibiotic therapies, drive GI inflammation and significant alteration of the GI microbiota (dysbiosis). Dysbiosis and inflammation are key factors in systemic inflammation and GI complications including malignancy. The following review examines the potential for probiotic and prebiotic therapies to provide clinical benefits through modulation of the microbiome. Evidence from randomised control trials suggest probiotics are likely to improve GI inflammation and reduce the incidence of CF pulmonary exacerbations. However, the highly variable, low-quality data is a barrier to the implementation of probiotics into routine CF care. Epidemiological studies and clinical trials support the potential of dietary fibre and prebiotic supplements to beneficially modulate the microbiome in gastrointestinal conditions. To date, limited evidence is available on their safety and efficacy in CF. Variable responses to probiotics and prebiotics highlight the need for personalised approaches that consider an individual’s underlying microbiota, diet, and existing medications against the backdrop of the complex nutritional needs in CF.

Abstract
A 10-year-old female with cystic fibrosis (CF), diagnosed by newborn screen, and pancreatic insufficiency was referred by gastroenterology to endocrinology for short stature (Z-score -3.5 SD). She had poor growth velocity and delayed bone age, although stunting of her growth was evident by age 6 years. Her karyotype was consistent with Turner syndrome (45,X). Growth hormone therapy has improved her growth velocity; she is tolerating it without side effects. At 12 years old, she has delayed puberty due to primary ovarian failure and will initiate estrogen replacement. Her case highlights the importance of a comprehensive evaluation for short stature in individuals with CF. Poor growth velocity and extreme short stature should not be dismissed as expected comorbidities of CF. The differential for causes of short stature is broad, with some etiologies having significant sequalae and increased morbidity beyond that already seen in CF.

Abstract
Objectives: This study aimed to monitor the health and nutritional status of pediatric cystic fibrosis (CF) patients via telehealth services during the novel coronavirus disease 2019 (COVID-19). Additional aims were to determine the level of anxiety in the patients and their caregivers and to determine the COVID-19 transmission status among CF patients. Materials and Methods: The CF team supported the patients via remote contact. During telehealth services interviews, in addition to obtaining information about the patients' anthropometric measurements, health status, and CF-related complaints, the State-Trait Anxiety Inventory (STAI) was administered to the patients and controls. The Hospital Anxiety and Depression Scale (HAD) was administered to their caregivers. Results: The study included 144 pediatric CF patients (74 males and 70 females). Mean age of the patients was 8.9 years. In all, 42 (29.2%) of the patients were tested for COVID-19, of which 4 were positive. The mean STAI score was significantly lower in the patient group than in the control group (p < 0.001). The mean HAD anxiety score was significantly higher in the caregivers of the CF patients, compared to the caregivers of the controls (p = 0.005). In addition, the mean HAD depression score was significantly higher in the caregivers of the CF patients (p < 0.001). Conclusions: Telehealth is an innovative method for providing health care services while maintaining social distance and avoiding the risk of exposure and spread of COVID-19. Telehealth services reduce patient and parental anxiety and increase the level of confidence in managing CF-related complications.

Abstract
We investigated the relationship between self-reported adherence to pancreatic enzyme replacement therapy (PERT), nutritional status, and all-cause hospitalization in cystic fibrosis (CF) patients with a record of PERT use. Association of self-reported annual PERT use rate (adherence) with annual hospital admission rate (HAR) and annual total hospital nights (THNs) were analyzed for 5301 children (2000–2012) and 13,989 adults (2000–2013) from the CF Foundation Patient Registry. Multivariate linear regression was used to determine the association of HAR and THN with mean annual PERT use rate, cumulative PERT use rate, mean body mass index (BMI) (adult) or BMI percentile (pediatric), age, and sex. The median annual PERT use rate was 87% in children and 80% in adults. Statistically, higher annual PERT use, longer cumulative PERT, and higher BMI percentile (children) or BMI (adults) were significantly (p < 0.0001) associated with lower annual HAR and fewer annual THN in children and adults. Female sex was associated with higher annual HAR and more annual THN in children and adults (p < 0.05). Results indicate self-reported adherence to PERT, increased BMI, and male sex were associated with fewer hospital admissions and annual hospital nights in CF patients.

Abstract
RESUMO O objetivo deste trabalho é avaliar a capacidade de exercício e nível de atividade física diária de crianças e adolescentes com fibrose cística e associar com estado nutricional, função pulmonar, tempo de hospitalização e uso de antibióticos. Trata-se de estudo transversal em indivíduos com fibrose cística entre 6 e 18 anos, registrando-se informações sobre perfil clínico, histórico de hospitalizações e uso de antibióticos. Os participantes foram submetidos à espirometria, bioimpedância, avaliação da capacidade de exercício com teste de Shuttle modificado (MST), o nível da atividade física foi medido por meio do questionário internacional de atividade física (IPAQ) e usando acelerômetro por 5 dias. Participaram 30 indivíduos com idade de 11,2 ± 3,6 anos e volume expirado forçado (VEF1) de 68,0 ± 24,8%. A mediana da distância percorrida no MST foi de 820 metros (66,3%) e demonstrou associação com a função pulmonar (r = 0,78), estado nutricional (r = 0,38), tempo de hospitalização (r = -0,42) e uso de antibióticos (r = -0,46). De acordo com o questionário, 20 pacientes (64,6%) foram classificados como sedentários, o acelerômetro revelou que os indivíduos passam 354,2 minutos em atividades sedentárias e apenas 14,9 minutos em atividades moderadas a vigorosas por dia. Quanto maior a porcentagem de tempo em atividade física moderada a vigorosa, maior o índice de massa corpórea (IMC) e menor o tempo de hospitalização. Assim, a capacidade de exercício e nível de atividade física em crianças e adolescentes com fibrose cística apresentou-se reduzida e associada com menores valores de IMC e aumento do tempo de hospitalização.

Abstract
Cystic fibrosis (CF) is a rare, progressive, multi-organ genetic disease. Ivacaftor, a small-molecule CF transmembrane conductance regulator modulator, was the first medication to treat the underlying cause of CF. Since its approval, real-world clinical experience on the use of ivacaftor has been documented in large registries and smaller studies. Here, we systematically review data from real-world observational studies of ivacaftor treatment in people with CF (pwCF). Searches of MEDLINE and Embase identified 368 publications reporting real-world studies that enrolled six or more pwCF treated with ivacaftor published between January 2012 and September 2019. Overall, 75 publications providing data from 57 unique studies met inclusion criteria and were reviewed. Studies reporting within-group change for pwCF treated with ivacaftor consistently showed improvements in lung function, nutritional parameters, and patient-reported respiratory and sino-nasal symptoms. Benefits were evident as early as 1 month following ivacaftor initiation and were sustained over long-term follow-up. Decreases in pulmonary exacerbations, Pseudomonas aeruginosa prevalence, and healthcare resource utilization also were reported for up to 66 months following ivacaftor initiation. In studies comparing ivacaftor treatment to modulator untreated comparator groups, clinical benefits similarly were reported as were decreases in mortality, organ-transplantation, and CF-related complications. The safety profile of ivacaftor observed in these real-world studies was consistent with the well-established safety profile based on clinical trial data. Our systematic review of real-world studies shows ivacaftor treatment in pwCF results in highly consistent and sustained clinical benefit in both pulmonary and non-pulmonary outcomes across various geographies, study designs, patient characteristics, and follow-up durations, confirming and expanding upon evidence from clinical trials.

Abstract
BACKGROUND Cystic fibrosis (CF) causes malabsorption of nutrients that exacerbate pulmonary problems. Nutritional interventions can improve pulmonary functions. We aimed to evaluate the effects of nutritional intervention in CF patients with malnutrition, and to determine if there is a correlation between nutritional status and pulmonary functions. METHODS The study included 143 CF patients (67 females) with a mean 2 year follow-up time. Patients' sociodemographic data, presenting symptoms and history were recorded. Height-for-age, weight-for-age, weight-for-length/height (WFL/H), and body mass index (BMI) were calculated in all patients. Patients were grouped as well nourished, mild malnutrition, moderate malnutrition, and severe malnutrition. These four groups were compared in terms of pulmonary function test results, lung infections, and the hospitalization rate. RESULTS Among the patients with a WFL/H or BMI z-scores that decreased, the frequency of lung infection was 74.1% and the hospitalization rate was 40.7%, versus 34% and 12.3%, respectively among the patients with a WFL/H or BMI z-scores that increased. The difference was significant (P = 0.02 and P = 0.01, respectively). The difference in bacterial lung infections differed significantly between the four nutritional status groups (P = 0.002). Patients in the well-nourished group had significantly higher pulmonary function test scores than the other groups. The forced expiratory volume in the first second differed significantly between the patients with and without an increase in the WFL/H or BMI z-scores (P = 0.001). CONCLUSIONS The appropriate nutritional intervention to pediatric CF patients with malnutrition, decrease the frequency of lung infections, and improve respiratory function.

Early-Life Height Attainment in Cystic Fibrosis Is Associated with Pulmonary Function at Age 6 Years. Ann Am Thorac Soc 2021; 18:1335-1342. [PMID: 33476226 DOI: 10.1513/annalsats.202008-933oc] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Rationale: In contrast to the well-described association between early-life weight for age, body mass index (BMI), and later lung disease in people with cystic fibrosis (CF), the relationship between height-for-age (HFA) percentiles and respiratory morbidity is not as well-studied. We hypothesized that changes in HFA in children with CF in the first 6 years of life would be associated with pulmonary function at the age of 6-7 years. Objectives: To determine if an association exists between changes in HFA in early life and pulmonary function in school-aged children with CF. Methods: We performed a retrospective longitudinal cohort study of children with CF followed in the CF Foundation Patient Registry who were born between 2003 and 2010, had CF diagnosed before the age of 2 years, and were followed through at least the age of 7 years. Changes in annualized HFA were classified into mutually exclusive categories. Multivariable analysis of covariance models were used to test for an association between the percent-predicted forced expiratory volume in 1 second (FEV1) at the age of 6-7 years and height-trajectory categories. Results: There were 5,388 eligible children in the CF Foundation Patient Registry. The median (interquartile range) HFA at the age of 6-7 years was in the 39.5th (17.2th-64.9th) percentile. The mean (95% confidence interval) FEV1% predicted at the age of 6-7 years was 95.6% (95.1-96.1%). In a multivariable regression model, the mean (95% confidence interval) FEV1% predicted was higher for children with HFA that was always above the 50th percentile (97.8% [96.3-99.4%]) than for children whose height had been below the 50th percentile for at least 1 year and increased by ≥10 percentile points (95.1% [93.7-96.6%]), was stable (94.3% [92.8-95.7%]), or decreased by ≥10 percentile points (95.7% [94.2-97.3%]). The association between HFA categories and FEV1% predicted was not affected by adding the mean annualized BMI percentile at the age of 6-7 years to the regression model. Among those with HFA that decreased by ≥10 percentile points, there was a correlation between the nadir annualized HFA percentile and the FEV1% predicted at the age of 6-7 years. Conclusions: Children with CF with HFA that is always above the 50th percentile have the highest pulmonary function at the age of 6-7 years. Maintaining a BMI above the 50th percentile remains an important achievable goal for children with CF but is not the sole marker that should be examined in evaluating nutrition.

Abstract
OBJECTIVE Chronic undernutrition is a common phenomenon in Bangladesh. However, information is grossly lacking to report the correlation between chronic undernutrition trajectory and lung function in children. The aim of the current study was to understand the association between early-childhood chronic undernutrition trajectory and lung function at preadolescence. DESIGN The current study is a part of the 9-year follow-up of a large-scale cohort study called the Maternal and Infant Nutrition Interventions in Matlab. SETTINGS The current study was conducted in Matlab, a sub-district area of Bangladesh that is located 53 km south of the capital, Dhaka. PARTICIPANTS A total of 517 children participated in lung function measured with a spirometer at the age of 9 years. Weight and height were measured at five intervals from birth till the age of 9 years. RESULTS Over half of the cohort have experienced a stunting undernutrition phenomenon up to 9 years of age. Children who were persistently or intermittently stunted showed lower forced expiratory volume (ml/s) than normal-stature children (P < 0·05). Children who exhibited catch-up growth throughout 4·5 years from the stunted group showed similar lung function with normal counterparts, and a better lung function than in children with the same growth velocity or who had faltering growth. In the multivariable models, similar associations were observed in children who experienced catch-up growth than their counterparts after adjusting for covariates. CONCLUSION Our data suggest that catch-up growth in height during early childhood is associated with a better lung function at preadolescence.

Abstract
BACKGROUND Dietary intervention in cystic fibrosis (CF) has historically focused on high-energy diets to address malnutrition, with little attention on diet quality. With increased survival, CF complications such as impaired glucose tolerance (IGT) and cystic fibrosis related diabetes (CFRD) have increased in prevalence. In the absence of consensus on the management of IGT, the role of dietary intake, specifically carbohydrate quality, requires consideration. AIMS The aims of this study were to: 1) determine nutritional quality of dietary intake at an adult CF clinic and compare this to the Australian Dietary Guidelines 2) explore relationships between dietary intake, including glycaemic index (GI) and glycaemic load (GL), and glucose response variables using continuous glucose monitoring (CGM). METHODS Adults attending a Sydney hospital were recruited to undergo CGM for five-seven days and record dietary intake using a food record over the CGM period. The relationship between variables of dietary intake, including GI and GL and variables of glycaemic response, including mean amplitude of glycaemic excursions (MAGE), percentage of time in hyperglycaemic and euglycaemic range, were determined. RESULTS Eighteen participants completed the study with 87 full days of dietary and CGM data. Dietary intake was higher than recommendations in the Australian Dietary Guidelines in relation to grains and protein foods and only slightly higher in saturated fat. Bivariate correlations showed dietary GI was significantly positively associated with percentage of time in hyperglycaemic range. Dietary GL was significantly associated with SD, MAGE and percentage of time in euglycaemic range on CGM. Results remained significant when controlled for energy intake in partial correlation analyses. CONCLUSIONS This study suggests GI and GL may be important dietary factors influencing glucose metabolism in CF. Further studies exploring low GI or GL diets as a dietary intervention in CF are the next step.

Abstract
Introduction The impact of glutathione on pulmonary function remains elusive for patients with cystic fibrosis. The aim of this systematic review and meta-analysis is to explore the influence of glutathione versus placebo on pulmonary function of cystic fibrosis. Methods We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through May 2019, and randomized-controlled trials (RCTs) regarding the effect of glutathione on pulmonary function of cystic fibrosis are included in this meta-analysis. Results Four RCTs are included. Compared with control group in patients with cystic fibrosis, glutathione treatment shows positive impact on forced expiratory volume 1 second (FEV1) (mean difference [MD] = 0.19; 95% confidence interval (CI), 0.10–0.28; P < .0001) and body mass index (MD = 0.27; 95% CI, 0.02–0.51; P = .03), but has no obvious influence on 6-minute walk test (standard MD = 0.28; 95% CI, −0.08 to 0.64; P = .13), number of exacerbations (MD = −0.10; 95% CI, −0.34 to 0.15; P = .43), abdominal pain or distal intestinal obstruction (risk ratios [RR] = 0.78; 95% CI, 0.32–1.90; P = .58), or hemoptysis (RR = 1.87; 95% CI, 0.43–8.26; P = .41). Conclusions Glutathione treatment provides some benefits to improve pulmonary function of patients with cystic fibrosis, as evidenced by the increase in FEV1.

Abstract
BACKGROUND We aimed to assess whether final height in children with cystic fibrosis (CF) is affected by body mass index (BMI), BMI increase, pulmonary function, and cystic fibrosis-related diabetes (CFRD). STUDY DESIGN A longitudinal, retrospective study was performed in a cohort of 57 patients with CF (30 boys, 27 girls) born between 1997 and 2001. Height and weight were recorded annually from ages 0.5 to 10 years and biannually up to the age of 18. Measurements were converted to height-for-age-adjusted-for-target-height (HFA-TH) and BMI-for-age z-scores. Analyses were performed using the independent t tests and the Pearson's correlation. RESULTS For both boys and girls, HFA-TH and BMI-for-age z-scores were significantly lower in the first year of life, these scores increased rapidly until the age of 11 and 8 years, respectively. In boys, HFA-TH z-scores declined during puberty, with subsequently significantly impaired final height (z-score, -0.56, n = 30, standard deviation [SD] = 0.81, P = 0.001). In girls, HFA-TH z-scores briefly declined after the age of 8 years, but then increased to a z-score of -0.21 (n = 27, SD = 0.87) at age 18, which is not significantly lower than the national average (P = 0.22). Pulmonary function and the presence of CFRD were not associated with final height. However, rapid BMI increase between ages 1 and 6 was negatively associated with final height in boys (n = 29, r =-0.420; P = 0.023) and girls (n = 25, r =-0.466; P = 0.019). CONCLUSIONS In boys and girls, early BMI increase was associated with impaired final height. We suggest that early childhood serves as a "window" in which nutritional variations may program subsequent growth. Further refinement of nutritional strategies could be needed.

Abstract
The hypothesis of this study was that Hdac6 depletion would restore cystic fibrosis (CF) responses to bacterial challenge to more wild type profiles using a CF mouse model. CF mice harboring the F508del Cftr mutation respond to bacterial challenge with 25,000 CFU Pseudomonas aeruginosa embedded into agarose beads to slow clearance. CF mice respond significantly more aggressively to this challenge compared to WT mice with respect to bacterial clearance, weight loss, neutrophil recruitment, and MIP-2 production. Depletion of Hdac6 expression in the CF mice (CF/Hdac6) significantly improves these responses to more WT levels. Weight loss in response to infection is most severe in CF mice and significantly attenuated in CF/Hdac6 mice. Bacterial levels are reduced at a faster rate in CF/Hdac6 mice compared to CF mice where infection persists. Percent neutrophils in lung lavage fluid post-infection are significantly higher in CF mice, but returned to WT levels with CF/Hdac6 mice. Similarly, CF Mip-2 levels are restored to WT levels in the absence of Hdac6 expression. These data demonstrate that Hdac6 depletion restores CF responses to bacterial challenge to WT-like profiles and offer a potential therapeutic avenue for addressing inflammation and infection in CF airways independently of Cftr correction.

Abstract
Introduction. Optimizing nutrition remains the cornerstone of therapy for patients with cystic fibrosis (CF) since it is associated with better pulmonary function and survival. However, a significant proportion of patients still fail to achieve normal growth and nutritional status. Areas covered. This review describes the current challenges in providing effective nutritional therapy in CF with a focus on the current issues related to energy imbalance, dietary composition, adherence to nutritional recommendations, pancreatic enzyme replacement therapy, and the effects of modulators of the CF transmembrane conductance regulator. Expert opinion. CF is a multisystemic disease that requires a personalized nutritional approach with accurate evaluation of energy balance. There is an urgent need for evidence-based recommendations on the dietary composition, in consideration of the increasing prevalence of overweight, diabetes and the potential effects of fatty acids on inflammation and immune response. More research into new pancreatic enzyme formulations is also required.

Abstract
Cystic fibrosis (CF)-related diabetes is associated with increased mortality. We analysed the clinical and glycemic profiles of two cohorts of patients treated according to the same guidelines in France and Canada. To investigate incidence differences in phenotypic and glucose abnormalities and to explore the evolution over a 4-year follow-up period, two cohorts of 224 Canadian and 147 French adult CF patients (≥18 years) without treated CF-related diabetes (CFRD) were followed over a 4 year period. In each of these groups, we investigated the longitudinal relationship between glucose tolerance and pulmonary function. An annual 2-hour oral glucose tolerance test was performed: fasting blood glucose (G0) and 2-h blood glucose (G2) were measured. Patients were classified at inclusion according to their glucose tolerance status: Normal glucose tolerant, abnormal glucose tolerant or de novo CFRD. Age, sex ratio and proportion of F508del homozygous patients were not statistically different between both cohorts. Canadian patients had better pulmonary function (median %FEV1 (IQR): 71.0 (55.0–82.0) vs. 64.0 (40.0–78.0), p < 0.001) and greater body mass index (BMI; median BMI in kg/m2) (IQR) 21.1 (19.5–22.8) vs. 19.9 (18.4–21.4), p < 0.001). Glucose values: G0 (5.4 (5.0–5.9) vs. 4.8 (4.5–5.1) mmol/L, p < 0.001) and G2 (7.6 (5.8–9.7) vs. 6.5 (5.2–8.5) mmol/L, p = 0.001) were higher in the Canadian cohort translating into a higher incidence of de novo CFRD diagnosis (19.2 vs. 9.8%, p = 0.003). Decline in FEV1 over time was not different between patients according to glucose tolerance groups. Despite higher glucose levels and incidence of de novo CFRD, Canadian CF patients have a better lung function and a higher BMI than French patients. In spite of these differences between the cohorts, the decline in FEV1 in patients with abnormal glucose tolerance is similar between these groups.

Abstract
Background Cystic fibrosis (CF) is a disease in which nutritional barriers are diverse and common, with malnutrition greatly influencing pulmonary trajectory and overall outcomes. Despite this, the most effective methods to optimize CF nutrition are unknown, and literature describing patients’ perspectives on their specific nutritional needs is lacking, particularly in the modern era of CF care. This study aimed to identify the most important nutritional needs and desired health-improvement resources in a contemporary adult CF cohort. Methods A 14-question investigator-designed survey addressing nutrition concerns, preferred health-improvement resources, and dietary/exercise routines was administered to CF adults. Clinical characteristics and survey responses are presented with descriptive statistics, and responses compared by body mass index (BMI) category (< 18.5 kg/m2; 18.5–24.99 kg/m2; 25–29.99 kg/m2; ≥30 kg/m2), gender, and socioeconomic status using Chi square or Fisher’s Exact testing. Results Of 66 total patients, nine (13.6%) were underweight (BMI < 18.5 kg/m2), while 19 (28.8%) were overweight or obese (BMI ≥ 25 kg/m2). In the overall cohort, the most common primary concern was preventing weight loss [in 20/66 patients (30.3%)], but there were significant differences by BMI (p < 0.001), with the most common concern in the overweight subgroup being preventing weight gain. Fifteen (46.9%) men (BMI mean 20.7, range 16.4–29.2 kg/m2) listed preventing weight loss as the primary concern, compared to only 5 (14.7%) women (BMI mean 18.4, range 16.2–19.9 kg/m2), representing a trend toward a difference in primary concerns by gender (p = 0.066). The most commonly desired health-improvement resource was online CF nutrition and fitness information, found in 26 patients (39.4%) in the overall cohort, without significant differences by BMI (p = 0.814) or gender (p = 0.199). Financial assistance was the preferred resource in 17 (26.2%), without differences by socioeconomic status (p = 0.367). Conclusions We identified a wide variety of nutritional needs in CF adults, including a high prevalence of overweight status, many patients desiring weight loss, and many seeking financial resources. Our findings support the individualization of modern-day CF nutrition programs and development of online resources, in an effort to address the heterogeneous barriers that exist in the contemporary CF population and improve outcomes in patients with the disease.

[PMID: 30803355 PMCID: PMC6366006 DOI: 10.1177/1753466618820186] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 11/27/2018] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Lumacaftor/ivacaftor combination therapy is efficacious and generally safe for patients with cystic fibrosis (CF) homozygous for the F508del-CF transmembrane conductance regulator (CFTR) mutation. However, long-term survival benefits of lumacaftor/ivacaftor (LUM/IVA) cannot yet be quantified. Simulation models can provide predictions about long-term health outcomes. In this study, we aimed to project long-term health outcomes of LUM/IVA plus standard care (SC) in patients with CF homozygous for F508del-CFTR. METHODS This modeling study was an individual patient simulation in US patients aged ⩾6 years with CF, homozygous for F508del-CFTR. The primary outcome was projected survival among (a) a cohort of patients who ever initiated LUM/IVA, accounting for treatment discontinuations, and (b) a cohort of patients who remain on continuous LUM/IVA. Patient characteristics and model parameters were derived from clinical trials: VX14-809-109, VX13-809-011B, TRAFFIC/TRANSPORT, and PROGRESS; published literature; and the US CF Foundation Patient Registry. RESULTS Lumacaftor/ivacaftor + SC is expected to increase median survival by 6.1 years versus SC alone, accounting for treatment discontinuations. The incremental median predicted survival versus SC assuming initiation of LUM/IVA at ages 6, 12, 18, and 25 years was 17.7, 12.6, 8.0, and 3.8 years, respectively. Assuming lifetime treatment with LUM/IVA, incremental median survival was predicted to be 7.8 years longer in the LUM/IVA + SC cohort. Initiating LUM/IVA at ages 6, 12, 18, and 25 years and assuming lifetime treatment resulted in incremental median predicted survival of 23.4, 18.2, 11.0, and 4.8 years, respectively. CONCLUSIONS Lumacaftor/ivacaftor is projected to increase survival for patients with CF. Initiation at an early age and treatment persistence result in further increments in projected survival.

Abstract
This clinical observation describes the enteral nutrition (EN) management of 2 toddlers at high nutrition risk due to cystic fibrosis (CF), exocrine pancreatic insufficiency, and comorbid medical conditions. The first case report describes a boy with severe malabsorption after intestinal resection. The second case report reviews a boy with CF and neuroblastoma. When pancreatic enzyme replacement therapy with EN was not effective or appropriate, use of an in-line digestive cartridge was initiated. While using the digestive cartridge, both children showed improvements in their anthropometric measures. This observation reviews the nutrition management throughout their clinical course and describes the use of a digestive cartridge with EN.

Abstract
INTRODUCTION Progressive lung disease is the major cause of morbidity and mortality in patients with cystic fibrosis (CF). Methods of correctly predicting the future progression of lung disease in patients with CF are essential for directing aggressive treatment to prevent loss of lung function and end stage respiratory failure. Areas covered: This review addresses predictors of respiratory disease progression in patients with CF. We searched Web of Science and Medline, with no restriction on publication date, with the search terms 'cystic fibrosis' and 'disease progression', 'lung function decline', 'prognosis', 'prediction/predictive', 'prediction/prognostic scores', 'risk factors', 'outcome measures/endpoints/disease surrogate', 'longitudinal/long term', 'statistical model', and 'survival'. Expert commentary: Forced expiratory volume in 1 sec (FEV1) and rate of FEV1 decline, remain the most significant predictors of mortality in patients with CF while CT scores and airway secretion biomarkers are the main predictors of early CF lung disease. Comprehensive scores incorporating clinical, lung function, imaging and laboratory data will become essential in the future for predicting disease progression and for use in clinical trials. Early interventions may delay the progression of structural lung disease.

Abstract
RATIONALE Neuroendocrine cell hyperplasia of infancy (NEHI) typically presents in infancy with tachypnea, retractions, and hypoxemia. Some infants have failure to thrive, yet the frequency of this and other non-respiratory phenotypic features have not been delineated. While gradual improvement occurs, the clinical course is variable and the duration of supplemental oxygen requirement has not been defined. OBJECTIVES Our objective was to identify factors in NEHI that may drive differences in clinical course. We hypothesized that failure to thrive would be associated with greater duration of supplemental oxygen use. METHODS Children with NEHI were identified as a nested retrospective cohort within an ongoing observational prospective study. An electronic questionnaire evaluating health status was distributed to the parents/guardians. Clinical data were obtained via chart review and parent interview. RESULTS Of 42 children, 74% had a diagnosis of failure to thrive during their clinical course. Time to event analysis demonstrated that 50% discontinued daytime and nighttime oxygen at 32 and 87.5 months after initiation, respectively. Diagnosis of failure to thrive was associated with longer continuous oxygen supplementation, P = 0.03. Additional parental concerns identified through the electronic questionnaire included developmental delays, multiple hospitalizations, and delays in diagnosis. CONCLUSIONS NEHI is associated with substantial respiratory and extra-pulmonary morbidity. Failure to thrive may be associated with greater respiratory morbidity, though further studies are required to define this interaction. Determining the association of these comorbidities and respiratory course in NEHI may enable development of strategies to improve these modifiable factors and potentially pulmonary outcomes.

Abstract
Background The Cystic Fibrosis (CF) center in Roscoff (Brittany) has been involved in therapeutic education programs (TEP) since 2006 and took part in the pilot phase of the French quality improvement program (QIP) since 2011. The aim was to improve the nutritional status of children with cystic fibrosis aged 2-12 years old in order to optimize their health status as they enter adolescence. Methods A multidisciplinary quality team was created in order to select and address a specific health problem among our pediatric population. Following analysis of yearly indicators for our CF center, our team chose to improve quality of care concerning nutritional status of children aged 2-12 years old. Factors influencing efficacy were studied, tools were developed to implement a new nutritional program, results were analyzed on a real-time basis. Results Over the 3 year period, all patients from 2 years of age, were monitored with the new follow-up program (2012: N = 34; 2014: N = 44). Each patient was followed up at every clinic visit, their BMI z-score was calculated to decide their nutritional risk and personalize their follow-up program consequently. Between 1/1/2012 and 31/12/2014, the mean BMI z-score of the open cohort improved from −0.49 to −0.22. Conclusions Since 2014, focus on nutrition using the newly-adapted program has become routine practice at each follow-up visit. Patients and parents expressed a high level of satisfaction (75% very satisfied). The follow-up program aimed at improving nutritional status for children aged 2-12 years old was successfully implemented and integrated into routine practice; it was therefore extended to all children with CF (1 month - 18 years) in our center. The relationship among professional and patients and parents was strengthened.

Abstract
BACKGROUND In children with cystic fibrosis (CF), recovery from growth faltering within 2 years of diagnosis (Responders) is associated with better growth and less lung disease at age 6 years. This study examined whether these benefits are sustained through 12 years of age. METHODS Longitudinal growth from 76 children with CF enrolled in the Wisconsin CF Neonatal Screening Project was examined and categorized into 5 groups: R12, R6, and R2, representing Responders who maintained growth improvement to age 12, 6, and 2 years, respectively, and I6 and N6, representing Non-responders whose growth did and did not improve during ages 2-6 years, respectively. Lung disease was evaluated by % predicted forced expiratory volume in one second (FEV1) and chest radiograph (CXR) scores. RESULTS Sixty-two percent were Responders. Within this group, 47% were R12, 28% were R6, and 25% were R2. Among Non-responders, 76% were N6. CF children with meconium ileus (MI) had worse lung function and CXR scores compared to other CF children. Among 53 children with pancreatic insufficiency without MI, R12 had significantly better FEV1 (97-99% predicted) and CXR scores during ages 6-12 years than N6 (89-93% predicted). Both R6 and R2 experienced a decline in FEV1 by ages 10-12 years. CONCLUSIONS Early growth recovery in CF is critical, as malnutrition during infancy tends to persist and catch-up growth after age 2 years is difficult. The longer adequate growth was maintained after early growth recovery, the better the pulmonary outcomes at age 12 years.

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.

Abstract
BACKGROUND Pediatric cystic fibrosis (CF) patients suffer high rates of undernutrition, subject to several parameters. We aimed to assess growth and nutritional status of Greek children and adolescents with CF. METHODS Eighty-four patients (35 boys) formed the sample. Anthropometrics and FEV1 were measured, growth and weight status were assessed. Body mass index (BMI), arm circumference (MUAC), fat (MUAFA) and muscle (MUAMA) were calculated. RESULTS In the total sample, 6.0% of the patients were underweight, 4.8% stunted, 8.3% wasted and 17.9% in nutritional failure, whereas 59.5% attained the ideal BMI for CF. FEV1 positively associated with BMI (B=0.03, p≤0.003), weight (B=0.03, p≤0.003) and MUAMA z-scores (B=0.04, p≤0.005). Meconium ileus negatively associated with FEV1 (B=-14.17, p≤0.003) and stature (B=-0.65, p≤0.043). Pancreatic insufficiency negatively influenced MUAC and MUAFA z-scores (p≤0.05 for both). CONCLUSIONS The examined CF patients appear to be thriving. Unlike published research, the participants' sex, gene mutation and acquisition of pathogens did not affect growth.

Abstract
OBJECTIVE To determine the prevalence of malnutrition in patients attending an adult cystic fibrosis (CF) program and to investigate the associations of malnutrition with the clinical characteristics of those patients. METHODS This was a cross-sectional study involving patients with clinically stable CF patients (16 years of age or older). The patients underwent clinical assessment, nutritional assessments, pulmonary function tests, and pancreatic function assessment. They also completed a questionnaire regarding diet compliance. On the basis of their nutritional status, the patients were classified divided into three groups: adequate nutrition; at nutritional risk; and malnutrition. RESULTS The study has included 73 patients (mean age, 25.6 ± 7.3 years), 40 of whom (54.8%) were female. The mean body mass index was 21.0 ± 3.0 kg/m2 and the mean FEV1 was 59.7 ± 30.6% of predicted. In this sample of patients, 32 (43.8%), 23 (31.5%), and 18 (24.7%) of the patients were allocated to the adequate nutrition, nutritional risk, and malnutrition groups, respectively. The logistic regression analysis identified three independent factors associated with the risk of malnutrition: Shwachman-Kulczycki score, percent predicted FEV1; and age. CONCLUSIONS Malnutrition remains a common complication in adolescents and adults with CF, despite dietary advice. Malnutrition is associated with age, clinical severity, and lung function impairment.

Abstract
Growth failure in cystic fibrosis (CF) patients has been well-documented and shown to correlate with poorer disease outcomes. This observation is also true in CF animal models, including mouse, pig, rat, and ferret. The etiology underlying growth deficits is unknown, and our previous work demonstrated reduced tubulin acetylation in CF cell models and tissue that is correctable by inhibition of histone deacetylase-6 (HDAC6). Here, we hypothesize that loss of HDAC6 will improve growth phenotype in a CF mouse model. Hdac6 knockout mice were crossed with F508del (CF) mice to generate F508del/Hdac6 (CF/HDA) mice. Growth, fat deposits, survival, and bioelectric measurements were analyzed. CF/HDA mice displayed improvements in length and weight with no correction of CFTR function. Mechanistically, Igf1 levels likely account for increased length and improvements in fertility. Weight gain is attributed to increased fat deposits potentially mediated by increased adipocyte differentiation. CF-related growth deficits can be improved via inhibition of HDAC6, further implicating it as a potential therapeutic target for CF.

Abstract
OBJECTIVES The present study sought to determine the long-term growth consequences after a pulmonary exacerbation in children with cystic fibrosis (CF). METHODS Retrospective cohort study of pediatric patients with CF with a hospital admission for a pulmonary exacerbation. Logistic regression used to determine risk factors for failure to recover baseline body mass index (BMI) percentile. RESULTS Of 72 patients, 43% failed to recover their baseline BMI percentile 12 months after discharge and these patients also had a lower forced expiratory volume in 1 second at follow-up. A greater decrease in weight percentile from baseline to admission was the only risk factor identified (odds ratio 0.83, P = 0.0015). CONCLUSIONS Greater decrease in weight percentile from baseline to admission predicts failure to recover BMI percentile 1 year after a pulmonary exacerbation. Children with CF with poor growth preceding a pulmonary exacerbation continue to be at risk for long-term nutritional failure despite treatment for pulmonary exacerbation.

Articles that addressed the long term association of growth and nutritional parameters, with an emphasis on growth, with pulmonary disease in cystic fibrosis, were included, and we excluded those that addressing only the relationship between nutritional parameters and cystic fibrosis and those in which the aim was to describe the disease. Data synthesis: Seven studies were included, with a total of 12,455 patients. Six studies reported relationship between growth parameters and lung function, including one study addressing the association of growth parameters, solely, with lung function, and all the seven studies reported relationship between nutritional parameters and lung function. Conclusions: The review suggests that the severity of the lung disease, determined by spirometry, is associated with body growth and nutritional status in cystic fibrosis. Thus, the intervention in these parameters can lead to the better prognosis and life expectancy for cystic fibrosis patients.

Abstract
Although outcome data for individuals with cystic fibrosis (CF) have shown consistent improvements throughout the twentieth century, more recent national registry data suggests that outcomes have reached a plateau. Median values for nutritional outcomes in CF currently cluster around the fiftieth centile for the normal population. These data suggest that up to half of CF patients have sub-optimal body mass index (BMI) which might have a significant adverse impact on their respiratory status. BMI might be underestimating the extent to which more important lean body mass might also be reduced. Nutritional decline is a particular problem during adolescence and commonly persists into early adult life. Current treatment strategies to optimize nutrition include the use of high energy diets, proton pump inhibitors and optimal use of enzyme preparations including higher strength preparations to decrease pill burden. Whilst these are all of potential benefit, poor adherence to nutritional care recommendations is probably the greatest impediment to future health improvement. More effective strategies to impact on treatment adherence are needed.

Abstract
In recent years, much effort has been directed at redefining malnutrition in the pediatric population to include the acute clinical population in addition to the more traditional ambulatory populations. In 2013, an expert panel convened to perform a critical review of available literature to craft a new approach to malnutrition. Closely thereafter, the Academy of Nutrition and Dietetics and the American Society for Parenteral and Enteral Nutrition published recommended indicators for the identification and documentation of malnutrition in pediatric populations. The purpose of this article is to review the domains within the new definition of malnutrition in pediatric practice, describe populations in which the recommended indicators for identification and management are problematic in clinical practice, give case studies that apply the new definition, and finally describe the implementation of a malnutrition identification program within a large tertiary care children's hospital.

Association of the relative change in weight and body mass index with lung function in teenagers and adults with cystic fibrosis: Influence of gender and diabetes. ACTA ACUST UNITED AC 2015; 62:422-9. [PMID: 26311609 DOI: 10.1016/j.endonu.2015.06.009] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2015] [Revised: 06/20/2015] [Accepted: 06/25/2015] [Indexed: 01/04/2023]
Abstract
BACKGROUND Nutritional status is a prognostic factor in cystic fibrosis. Prevention of nutritional impairment and weigh loss are major clinical objectives because they are associated with worsening of lung function and increased mortality. OBJECTIVE To identify a potential relationship of clinical nutrition parameters, and their relative changes, with lung function (FEV1%) in a cohort of adolescent and adult patients with CF. METHODS A retrospective analysis of 64 patients older than 14years. Weight, height, BMI, and lung function data were collected at a period of disease stability, both in the year of the first abnormal oral glucose tolerance test (OGTT) and in the previous year. Relative changes in weight and BMI, and their relationship with FEV1%, were determined by linear regression and ANOVA tests; influence of gender and diabetes was also assessed. RESULTS Mean age of the series (28 females and 36 males) was 26.8years. Normal glucose tolerance (NGT) was found in 26.7%, while 18.3% had diabetes without impaired fasting glucose (CFRD without FPG). Mean BMI was 20.32, with a mean weight of 53.53kg; 32.8% had BMI<18.5, and only 4.7% were overweight. Overall, a positive relative change in weight (≥6%) was associated with an increase in FEV1% (9.31%), as compared to those with a greater weight loss (at least 2%), who had a 12.09% fall in FEV1. Patients with CFRD without FPG had poorer lung function if they had a negative relative change in weight by at least 2% as compared to NGT. CONCLUSIONS In patients with CF, a relative weight gain is positively associated to FEV1%, while a relative weight loss of at least 2% has a significant negative impact on lung function.

Abstract
OBJECTIVE Our study aimed to develop a survey that could be used by nurses during regular cystic fibrosis (CF) clinic visits, providing clinicians with a standardized means of longitudinally assessing and monitoring symptom progression in their patients. In addition, the use of this survey would provide an opportunity for patient engagement and relationship building, thereby enhancing patient education and improving adherence to treatment. This is the first such survey designed specifically for use in Arab populations. . METHODS The Cystic Fibrosis Symptom Progression Survey (CF-SPS) was developed using previously published patient reported outcomes relating to pulmonary exacerbations in CF. It contains 10 items that provide a patient-focused account of symptoms. The survey was translated into Arabic and was completed by 12 patients on 139 occasions over 22 months. The psychometric properties of the survey were evaluated, as was the relationship between the survey findings and other known clinical measures of health status in CF. . RESULTS The CF-SPS performs well as a psychometrically valid clinical tool, with good internal consistency as determined by Cronbach's alpha analysis. Our results suggest that the CF-SPS is able to identify significant declines in health status in line with routine clinical patient assessment (chest sounds, body mass index and admissions). As such it is a useful tool that can support clinical decision making in the care of Arabic speaking CF patients. . CONCLUSION We recommend the CF-SPSa (Arabic version) as a valid tool for the longitudinal monitoring of symptom progression in CF in Arabic speaking populations.

Abstract
The malabsorption blood test (MBT), consisting of pentadecanoic acid (PA), a free fatty acid, and triheptadecanoic acid (THA), a triglyceride that requires pancreatic lipase for absorption of the heptadecanoic acid (HA), was developed to assess fat malabsorption in patients with cystic fibrosis (CF) and pancreatic insufficiency (PI). The objective was to construct a population pharmacokinetic (PK) model to describe PA and HA disposition in healthy subjects and CF subjects. A model was simultaneously fit to PA and HA concentrations, consisting of 1-compartment disposition and a transit model to describe absorption. PA bioavailability estimates for CF subjects without pancreatic enzyme administration (1.07 [0.827, 1.42]) and with enzymes (0.88 [0.72, 1.09]) indicated PA absorption comparable to healthy subjects. HA bioavailability in CF without enzyme administration was 0.0292 (0.0192, 0.0459) and with enzymes increased to 0.606 (0.482, 0.823). In CF, compared with taking enzymes with the MBT, HA bioavailability was further decreased by factors of 0.829 (0.664, 0.979) and 0.78 (0.491, 1.13) with enzymes taken 30 and 60 minutes after MBT, respectively. The MBT detected differences in fat absorption in subjects with CF with and without enzyme administration and with changes in enzyme timing. Future studies will address application of the MBT in CF and other malabsorption diagnoses.

Abstract
Growth failure is a common problem in many children with chronic diseases. This article is an overview of the most common causes of growth failure/growth retardation that affect children with a number of chronic diseases. We also briefly review the nutrition considerations and treatment goals. Growth failure is multifactorial in children with chronic conditions, including patients with cystic fibrosis, chronic kidney disease, chronic liver disease, congenital heart disease, human immunodeficiency virus, inflammatory bowel disease, short bowel syndrome, and muscular dystrophies. Important contributory factors to growth failure include increased energy needs, increased energy loss, malabsorption, decreased energy intake, anorexia, pain, vomiting, intestinal obstruction, and inflammatory cytokines. Various metabolic and pathologic abnormalities that are characteristic of chronic diseases further lead to significant malnutrition and growth failure. In addition to treating disease-specific abnormalities, treatment should address the energy and protein deficits, including vitamin and mineral supplements to correct deficiencies, correct metabolic and endocrinologic abnormalities, and include long-term monitoring of weight and growth. Individualized, age-appropriate nutrition intervention will minimize the malnutrition and growth failure seen in children with chronic diseases.
