Abstract
This article sets out to evaluate the prevalence and factors associated with adherence to enzyme replacement therapy among adolescents with cystic fibrosis. It is a cross-sectional, descriptive and observational study. Sociodemographic and clinical data were collected. The instruments used to assess adherence were: the Morisky-Green questionnaire and medication dispensation at the pharmacy, and interviews with structured questionnaires for the associated factors. Forty-four adolescents were interviewed. According to the method of the pharmacy medication dispensation analysis and the Morisky-Green questionnaire, the adherence of 45.5% and 11.4% was found, respectively. The higher adherence was observed in those with early diagnosis and the lowest in older adolescents and girls. The factors with the highest prevalence of non-adherence were: not taking enzymes when eating out of the home; only taking enzymes with major meals; normal lung function; with severe and very severe obstruction. The prevalence of adhesion to enzymes was low. Information related to the disease and treatment should be improved, especially among older adolescents and with impairment of lung function, with the creation of strategies and longitudinal studies to identify factors that interfere with adherence.

Abstract
OBJECTIVE To determine the relationship between nutritional status and dietary intake in patients with cystic fibrosis. METHODS Cross-sectional study involving 85 cystic fibrosis patients between 6 and 18 years of age. Dietary intake was evaluated by the 3-day diet record (weighing the food consumed). The outcome measures were the following nutritional status indicators: weight/height (W/H%) percentage, body mass index (BMI) percentiles, Z score for weight/age (W/A), Z score for height/age (H/A) and percentage of dietary intake compared with the Recommended Dietary Allowance (RDA). RESULTS The prevalence of well-nourished patients was 77.7%, using BMI above the 25th percentile as the cut-off value, and the W/H% was above 90% in 83.5%. The mean dietary intake, evaluated in 82 patients, was 124.5% of the RDA. In the univariate logistic regression analyses, we found a significant association between the independent variable calorie intake and the Z score for W/A. The multivariate analysis, based on the Z score for H/A and adjusted for FEV1, methicillin-resistant Staphylococcus aureus colonization and number of hospitalizations, demonstrated that a 1% increase in the calorie intake decreases the chance of having short stature by 2% (OR: 0.98; 95% CI: 0.96-1.00). Maternal level of education showed a borderline association (p = 0.054). CONCLUSIONS The prevalence of malnutrition was low in this sample of patients. The study model demonstrated an association between dietary intake and nutritional status. Dietary intake was a predictive factor of statural growth in patients with cystic fibrosis.

Abstract
OBJETIVO: Descrever o perfil de pacientes portadores de fibrose cística (FC). MÉTODOS: Estudo transversal, prospectivo, avaliando fibrocísticos de < 18 anos, durante o período de março a julho de 2006, em um centro de referência no nordeste do Brasil. A avaliação nutricional foi realizada pelo escore Z de altura/idade (A/I), peso/idade (P/I) e peso/altura (P/A) e %peso/altura (%P/A), além de medidas de composição corporal. Foram obtidos dados socioeconômicos e clínicos. RESULTADOS: Foram avaliados 21 pacientes, sendo 12 (57,1%) do sexo feminino. A média de idade de diagnóstico foi de 3,8 ± 3,9 anos, e as principais características ao diagnóstico foram infecção respiratória (85,7%), esteatorreia (66,7%) e déficit nutricional (47,6%). A média de escore Z para P/I, A/I e P/A, respectivamente, foi de -0,73 ± 0,28, -0,34 ± 0,21 e -0,73 ± 0,35. A média de %P/A foi de 94,52 ± 1,58. O percentual de desnutridos divergiu quando avaliado pelo escore Z e %P/A (déficit nutricional em 66,7% e 33,3%, respectivamente; p > 0,05). Os pacientes eutróficos apresentaram melhores condições socioeconômicas (p > 0,05) e clínicas, com melhor escore de Shwachman (p < 0,05) quando comparados aos distróficos. CONCLUSÕES: Eutrofia foi encontrada através dos indicadores nutricionais (P/I, A/I e P/A), ao passo que déficit nutricional foi encontrado quando avaliada a composição corporal. As condições socioeconômicas apresentaram-se favoráveis, principalmente em relação ao grau de instrução materna e renda per capita. A idade de diagnóstico foi maior do que o relatado na literatura, embora o escore de Shwachman e o número de infecções respiratórias tenham demonstrado que os pacientes tinham boas condições clínicas.

Abstract
OBJECTIVES To determine whether nutritional intake and status vary with age in children with cystic fibrosis (CF). METHODS Case-control study examining differences in nutritional parameters and intakes in 58 children with CF recruited from a regional centre (2000-2001) and 45 controls. Participants were divided into age groups of 5-8 years, 9-12 years and 13-16 years. Weight, height, body mass index and standard deviation scores were recorded. A 4-day food diary (51 CF, 31 controls) was calculated for macronutrients and micronutrients. RESULTS Energy intakes (%EAR) increased with age (112%, 115% and 116%, respectively) and were significantly higher in children with CF than controls. Lower weight and growth trends were observed in children ages 5 to 8 years (NS). Weight gain and growth was normal in children with CF ages 9 to 12 years but declined at 13 to 16 years (weight z score -0.85 vs 0.68 P = 0.003, height z score -0.54 vs 0.53 P = 0.002, body mass index z score -0.72 vs 0.41 P = 0.03). Lung function was the most significant predictor of nutritional status at 9 to 12 years (r2 = 0.37, P = 0.006) and 13 to 16 years (r2 = 0.31, P = 0.01), but was not significant in children ages 5 to 8 years. CONCLUSION Energy intakes increased with age in children with CF and exceeded that of healthy peers in all age groups. Weight gain and growth equaled that of healthy peers at 9 to 12 years but was suboptimal at 5 to 8 years and dramatically declines at 13 to 16 years. Energy intakes were unable to meet the clinical demands of children in these age groups. Both remain vulnerable and require greater nutritional targeting.

Abstract
BACKGROUND Most patients with cystic fibrosis (CF) require a higher energy and protein intake than their healthy peer group. There are few data on dietary intakes of adult patients. The aim of this study was to determine nutritional intakes in an adult population with CF. The impact of nutritional intervention and disease on macronutrient intake was examined. METHODS Retrospective cross-sectional analysis of 94 unweighed food diaries at annual review (1995-2000). Energy and protein intakes were compared to the estimated average requirement (EAR) for energy and reference nutrient intake (RNI) for protein. The effect of diet alone, oral supplements, enteral tube feeding, and cystic fibrosis related diabetes (CFRD), on macronutrient intake was examined and impact of pancreatic sufficency (PS) and lung transplantation. RESULTS Mean energy and protein intakes approached recommended CF guidelines, but in 72% of assessments these values were not achieved. Mean energy and protein intakes for patients on diet alone and protein intake for those with CFRD failed to meet recommendations. Oral supplementation and enteral tube feeding regimens increased energy and protein intake above recommended levels. No group achieved 40% total energy from fat. Patients receiving enteral tube feeds had the highest mean energy and protein intakes but lowest body mass index (BMI) and lung function. CONCLUSION Adequate mean energy and protein intakes in adult patients with CF mask subgroups of patients who fail to meet recommendations ie. diet alone, diabetic. Oral supplementation and enteral tube feeding increase energy and protein intake but fail to achieve an adequate BMI level in subjects with a decreased clinical status. Individual nutritional assessment remains essential.

Abstract
OBJECTIVES AND STUDY DESIGN In the present study, the caries experience (ie, the number of decayed, missing, and filled teeth) and oral cleanliness (ie, measures of plaque, calculus, and gingival bleeding) of patients homozygous for cystic fibrosis (CF; n = 42), patients heterozygous for CF (n = 48), and healthy control subjects (n = 62) were recorded and statistically analyzed. RESULTS Those who were homozygous for CF had a significantly lower caries experience than both the control subjects (P <.001) and those who were heterozygous for CF (P =.011). They also had significantly less gingival bleeding sites than the controls (P =.014) and those heterozygous for CF (P =.019). Patients heterozygous for CF showed significantly more extensive restorations than those who were homozygous (P =.015) and significantly more missing teeth than the controls (P =.008), whereas the controls had significantly more missing teeth than those who were homozygous for CF (P <.001). CONCLUSIONS Although those homozygous for CF are expected to have a high caries risk because of their essential sugar-rich diet, they did not have a significantly higher caries experience in this study. Their better gingival health and lower caries experience may be attributed to medication use (antibiotics) and as-yet unidentified intrinsic salivary mechanisms.

Abstract
PATHOGENESIS We have developed a model of the pathogenesis of malnutrition in cystic fibrosis. It consists of the relationship between nutrient balance and nutrient requirement. The validation has been conducted with respect to energy, but the same general principals can be applied to any nutrient. A patient with CF either loses weight or fails to grow normally if their absorbed energy intake is less than their total daily energy expenditure. Multiple factors have the potential to contribute to reduced energy intake including, anorexia, gastroeosophageal (GE) reflux leading to vomiting and hence food loss, as well as maldigestion. Another more recently recognized source of energy loss, is glucosuria as a result of CF related diabetes (CFRD). Conversely, lung inflammation appears to be related to increases in resting metabolic rate (RMR). Acute exacerbations of the chronic lung disease increases RMR which returns to a basal level some weeks after the inflammation is treated. In clinically stable patients with CF, RMR rises in a quadratic fashion as lung function falls. When FEV(1)is >85% predicted RMR is not different from controls, but it rises in a curvilinear fashion as FEV(1)falls. Initially it appears that patients adapt to their increased RMR by reducing their activity so their total daily energy expenditure (TDEE) is often no higher than controls. But this is by no means always the case. Furthermore good lung care requires CF patients to be involved in aerobic activities, hence their TDEE would rise. Although there has been considerable interest as to whether the genetic defect has an energy wasting effect, it appears genetic factors have little or no effect on RMR. TREATMENT This starts with making an energy diagnosis. First, a 3 day faecal fat balance study is conducted. This provides information with regard to intake as well as to maldigestion. In addition a history of GE reflux is sought, since it can readily be treated with H(2)-blockers. If significant fat malabsorption exists, efforts are made to improve pancreatic enzyme dose and function. The possibility of CFRD also needs to be considered. We measure the RMR of the patient using open circuit indirect calorimetry. Recommendations for diet therapy are based on estimated TDEE, which is determined from RMR taking into account faecal losses. Diet therapy places the emphasis on increasing the fat content of the diet. We have conducted a study to determine whether or not oral supplements help increase TDEE and they did not; they merely replaced food energy. Conversely, nocturnal gastrostomy supplemental feeding, while reducing voluntary food energy intake by about 20%, does result in a significant increase in total daily energy intake. Our target is to achieve a completely normal nutritional status. Long term follow-up of these patients has shown significantly better survival in patients who achieve normal nutritional status. The advent of lung transplantation has added another dimension. In our experience, following a successful lung transplant, most patients no longer need their supplemental gastrostomy feeding. SUMMARY Our clinic policy is to encourage a high fat diet (35-40% total energy) and our patients grow normally in height and weight until their lung disease deteriorates significantly. Patients who develop a negative energy balance seldom if ever respond to diet therapy and hence are candidates for supplemental nocturnal gastrostomy feeds. Gastrostomy fed patients constitute 3 to 5% of our total CF population of approximately 590 patients.

Abstract
Cystic fibrosis related diabetes mellitus is an increasingly recognized problem as survival in patients with cystic fibrosis improves. In a 5 year retrospective study of 627 children and adults attending Toronto cystic fibrosis clinics, we identified 57 (9%) patients with cystic fibrosis related diabetes mellitus; four (1.3%) of 301 children (<18 years) and 53 (16%) of 326 adults. The development of this complication of cystic fibrosis is associated with increased mortality, deteriorations in both respiratory and nutritional status, and the development of late microvascular, but not macrovascular, diabetic complications. Unfortunately, systematic review of the literature provides few well designed studies that provide sound evidence for clinical practice. Recommendations are therefore often based on anecdote, rather than physiological or outcomes research. Dietary therapy combines the principles of the dietary management of both cystic fibrosis and diabetes mellitus, but emphasizes the need for a high energy diet (> 100% of recommended daily intake) in patients with cystic fibrosis related diabetes mellitus. The importance of calories from fat is emphasized, with no restriction on total carbohydrate intake. Insulin intake mirrors carbohydrate intake. Routine dietary therapy is straightforward, but challenges occur due to both complications of cystic fibrosis and advancing disease. If a patient with cystic fibrosis related diabetes mellitus is malnourished, overnight enteral tube feeding is often used, with an adjusted insulin regimen. There is a great need for both physiological and outcomes research to provide sound scientific evidence for the dietary treatment of cystic fibrosis related diabetes mellitus.

Abstract
Malnutrition was once thought to be an inevitable consequence of cystic fibrosis (CF). It is now considered preventable but still contributes considerable morbidity in children. Malnutrition is linked to poorer pulmonary function, reduced survival and quality of life. As the anticipated lifespan of children with CF continues to lengthen, the prevention of malnutrition attains greater importance. This review explores the complex organic and psychosocial factors implicated in the aetiology of malnutrition associated with CF.

Abstract
Cystic fibrosis is commonly associated with energy deficiency in children and adults. Chronic undernutrition will lead to failure to thrive, wasting, and stunting of linear growth; nutrition and survival are intimately related in cystic fibrosis. These problems can simply be considered as energy imbalance, and management centers on restoration of energy balance. Specific nutrient deficiencies, such as fat soluble vitamins, are common in cystic fibrosis. Recent work has highlighted problems with bone density and also the prevalence of vitamin K deficiency. Management of nutritional problems can be complex, and injudicious treatment can further worsen the situation, as the relationship between high daily doses of pancreatic enzymes and the development of fibrosing colonopathy illustrates.

Abstract
This study evaluated adherence to current dietary recommendations of children with cystic fibrosis and mild lung disease and their siblings by comparing energy intake. Fifty children (25 with cystic fibrosis) aged between 7 and 12 years completed the study. Energy intake was assessed by weighed dietary intake, resting energy expenditure was used to calculate recommended daily intakes. The children with cystic fibrosis had significant deficits in Z scores for both height and weight compared with their siblings, but there was no difference in percentage of ideal weight for height. The cystic fibrosis group had a significantly higher energy intake per kilogram body weight per day but there was no difference in the percentage of energy derived from fat, protein or carbohydrate. Energy intake (per kg/day) and fat intake (g/kg) were both significant predictors of weight for height in the cystic fibrosis group. Targets for dietary management in cystic fibrosis should perhaps be related to fat intake per kilogram body weight.

Abstract
BACKGROUND Length of survival of females with cystic fibrosis is worse than it is in males. Results of current research have shown an important correlation among dietary intake, nutritional status, lung function, and survival. The purpose of this study was to explore gender differences in dietary intake and pancreatic enzyme replacement therapy in males and females with cystic fibrosis. METHODS The study was a cross-sectional measurement of clinical characteristics, energy, and fat intakes in males and females attending the cystic fibrosis outpatients clinics of the John Hunter Hospital, Newcastle, Australia. Twenty-nine subjects, (17 females and 12 males), completed 4-day weighed food records to measure total energy intake and the contribution of macronutrients and to document use of pancreatic enzyme replacement therapy. Energy intake was assessed as the percentage of the recommended energy intake for age and sex. RESULTS Females with cystic fibrosis had significantly lower energy and fat intakes than males, whereas the females used significantly more pancreatic enzyme replacement therapy. There were no significant differences in clinical characteristics between groups. CONCLUSION The results support the possibility that gender differences in the energy and fat intakes of older patients may contribute to differential median survival time of males and females with cystic fibrosis.
