Predicting budesonide performance in healthy subjects and patients with Crohn's disease using biorelevant in vitro dissolution testing and PBPK modeling. Eur J Pharm Sci 2021; 157:105617. [PMID: 33164838 DOI: 10.1016/j.ejps.2020.105617] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Revised: 10/02/2020] [Accepted: 10/19/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVES Drug product performance might be affected in Crohn's disease (CD) patients compared to healthy subjects due to pathophysiological changes. Since a low number of clinical studies is performed in this patient population, physiologically-based pharmacokinetic (PBPK) models with integrated results from biorelevant in vitro dissolution studies could be used to assess differences in the bioavailability of drugs. Using this approach, budesonide was used as model drug and its performance in healthy subjects and CD patients was predicted and compared against observed pharmacokinetic data. The in vitro release tests, under healthy versus CD conditions, revealed a similar extent of drug release from a controlled-release budesonide formulation in the fasted state, whereas in the fed state a lower extent was observed with CD. Differences in the physiology of CD patients were identified in literature and their impact on budesonide performance was investigated with a PBPK model, revealing the highest impact on the simulated bioavailability for the reduced hepatic CYP3A4 enzyme abundance and lower human serum albumin concentration. For CD patients, a higher budesonide exposure compared to healthy subjects was predicted with a PBPK population adapted to CD physiology and in agreement with observed pharmacokinetic data. Budesonide performance in the fasted and fed state was successfully predicted in healthy subjects and CD patients using PBPK modeling and in vitro release testing. Following this approach, predictions of the direction and magnitude of changes in bioavailability due to CD could be made for other drugs and guide prescribers to adjust dosage regimens for CD patients accordingly.

Nutrients 2019; 11:nu11071532. [PMID: 31284450 PMCID: PMC6683058 DOI: 10.3390/nu11071532] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Revised: 06/29/2019] [Accepted: 07/02/2019] [Indexed: 12/12/2022] Open
Abstract
This review discusses the personalised dietary approach with respect to inflammatory bowel disease (IBD). It identifies gene–nutrient interactions associated with the nutritional deficiencies that people with IBD commonly experience, and the role of the Western diet in influencing these. It also discusses food intolerances and how particular genotypes can affect these. It is well established that with respect to food there is no “one size fits all” diet for those with IBD. Gene–nutrient interactions may help explain this variability in response to food that is associated with IBD. Nutrigenomic research, which examines the effects of food and its constituents on gene expression, shows that—like a number of pharmaceutical products—food can have beneficial effects or have adverse (side) effects depending on a person’s genotype. Pharmacogenetic research is identifying gene variants with adverse reactions to drugs, and this is modifying clinical practice and allowing individualised treatment. Nutrigenomic research could enable individualised treatment in persons with IBD and enable more accurate tailoring of food intake, to avoid exacerbating malnutrition and to counter some of the adverse effects of the Western diet. It may also help to establish the dietary pattern that is most protective against IBD.

Abstract
INTRODUCTION These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries. METHODOLOGY The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. RESULTS Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation. CONCLUSIONS Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.

Abstract
BACKGROUND Malnutrition is a common sequela of Crohn's disease (CD) and may result in reduced skeletal muscle function and growth retardation. Energy requirements of parenterally fed hospitalized pediatric patients with active CD were measured using indirect calorimetry, to assess whether Food Agriculture Organization (FAO)/World Health Organization (WHO)/United Nations University (UNU) equations provide appropriate estimations of energy requirements in this patient population. METHODS Twenty hospitalized patients with active CD fed exclusively via parenteral nutrition (PN) were investigated. A chart review and patient interviews were conducted to assess disease duration, location, laboratory parameters, and symptomology associated with CD. Disease severity was quantified using the Pediatric Crohn's Disease Activity Index. Each subject underwent indirect calorimetry, bioelectrical impedance analysis, and anthropometric assessment once the ordered PN met estimated macronutrient requirements of each patient (predicted resting energy expenditure x1.3). Predicted resting energy expenditure (REE) was determined using the FAO/WHO/UNU equations. RESULTS REE showed a strong correlation with predicted REE (r(2) = .73, p < .01). CONCLUSIONS Measured REE did not significantly differ from predicted resting energy requirements. This indicates that REE for the parenterally fed pediatric patients with CD can be accurately predicted using the FAO/WHO/UNU equations.

Abstract
Assessment of micronutrient status of patients requiring long-term parenteral nutrition (PN) continues to be a challenge for clinicians. The scientific literature primarily consists of small studies and case reports. There are no evidence-based guidelines available. Clinicians rely on clinical assessment according to the patient's disease process, medication regimen, physical examination, and history of nutrient intake to determine existence or risk of micronutrient deficiency and toxicity. This paper will examine current scientific evidence and existing recommendations for the micronutrient assessment and management of patients requiring long-term PN.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) starting during childhood has been assumed to impair quality of life (QoL) of affected children. As this aspect is crucial for further personality development, the health-related quality of life (HRQOL) was assessed in a Swiss nationwide cohort to obtain detailed information on the fields of impairment. METHODS Data were prospectively acquired from pediatric patients included in the Swiss IBD Cohort Study. IBD activity was evaluated by PCDAI and PUCAI. The age adapted KIDSCREEN questionnaire was evaluated for 110 children with IBD (64 with Crohn's disease 46 with ulcerative colitis). Data were analyzed with respect to established reference values of healthy controls. RESULTS In the KIDSCREEN index a moderate impairment was only found for physical wellbeing due to disease activity. In contrast, mental well-being and social support were even better as compared to control values. A subgroup analysis revealed that this observation was restricted to the children in the German speaking part of Switzerland, whereas there was no difference compared to controls in the French part of Switzerland. Furthermore, autonomy and school variables were significantly higher in the IBD patients as compared to controls. CONCLUSIONS The social support for children with IBD is excellent in this cohort. Only physical well-being was impaired due to disease activity, whereas all other KIDSCREEN parameters were better as compared to controls. This indicates that effective coping and support strategies may be able to compensate the burden of disease in pediatric IBD patients.

Abstract
Objective. To analyze the effect of total parenteral nutrition (TPN) and enteral nutrition (EN) in patients with acute pancreatitis. Methods. Randomized controlled trials of TPN and EN in patients with acute pancreatitis were searched in NCBI and CBM databases and The Cochrane Controlled Trials Register. Six studies were enrolled into the analysis, and the details about the trial designs, characters of the subjects, results of the studies were reviewed by two independent authors and analyzed by STATA 11.0 software. Results. Compared with TPN, EN was associated with a significantly lower incidence of pancreatic infection complications (RR = 0.556, 95% CI 0.436∼0.709, P = .000), MOF (RR = 0.395, 95% CI 0.272∼0.573, P = .003), surgical interventions (RR = 0.556, 95% CI 0.436∼0.709, P = .000), and mortality (RR = 0.426, 95% CI 0.238∼0.764, P = .167). There was no statistic significance in non-pancreatitis-related complications (RR = 0.853, 95% CI 0.490∼1.483, P = .017). However, EN had a significantly higher incidence of non-infection-related complications (RR = 2.697, 95% CI 1.947∼3.735, P = .994). Conclusion. EN could be the preferred nutrition feeding method in patients with acute pancreatitis.

Abstract
BACKGROUND Metabolic syndrome (MS) is associated with an increased risk of cardiovascular disease. However, its prevalence in inflammatory bowel disease (IBD) patients remains largely unknown. This study was planned to determine the prevalence of MS in Japanese IBD patients. METHODS The prevalence of MS among outpatients with IBD aged 18 or older was studied using the modified National Cholesterol Education Program Adult Treatment Panel III definition. RESULTS A total of 107 quiescent IBD patients, including 76 ulcerative colitis (UC) patients and 31 Crohn's disease (CD) patients, were studied. Sufficient data were collected from a total of 102 patients. Prevalence of MS was significantly higher in UC (23.0%) patients compared to CD patients (7.1%). MS prevalence was substantially higher among male IBD patients (21.1%) compared to female IBD patients (12.9%), particularly in patients over 30 years of age. No difference was observed in the prevalence of MS between our IBD cohort and the general population in both males and females aged 40 years and older (P = 0.707 in males, P = 0.328 in females). IBD patients with MS were also older than those without (50.2 ± 15.0 vs. 38.0 ± 11.9 years, P = 0.013). In a logistic regression analysis, age was the statistically significant predictor of MS among IBD patients. The odds ratio (95% confidence interval) was 1.064 (1.017-1.114). CONCLUSIONS Prevalence of metabolic syndrome in our IBD patients was comparable to that of the general population. Because age was the independent risk factor for developing MS, evaluation for MS is needed for elderly IBD patients.

Abstract
Undernutrition as well as specific nutrient deficiencies has been described in patients with Crohn's disease (CD), ulcerative colitis (UC) and short bowel syndrome. In the latter, water and electrolytes disturbances may be a major problem. The present guidelines provide evidence-based recommendations for the indications, application and type of parenteral formula to be used in acute and chronic phases of illness. Parenteral nutrition is not recommended as a primary treatment in CD and UC. The use of parenteral nutrition is however reliable when oral/enteral feeding is not possible. There is a lack of data supporting specific nutrients in these conditions. Parenteral nutrition is mandatory in case of intestinal failure, at least in the acute period. In patients with short bowel, specific attention should be paid to water and electrolyte supplementation. Currently, the use of growth hormone, glutamine and GLP-2 cannot be recommended in patients with short bowel.

Abstract
Osteoporosis is now recognized as a problem in children with chronic illness. Decreased bone mineral density and increased risk of fracture have been reported in children with inflammatory bowel disease (IBD). Recent studies have led to a better understanding of the pathogenesis of bone loss. There are many risk factors for osteopenia and osteoporosis in children with IBD. Dual-energy x-ray absorptiometry remains the diagnostic procedure of choice for assessment of bone mineral density, but other modalities are being explored. Guidelines for diagnosis and treatment of osteoporosis in children have not been established. This article reviews the current understanding of osteopenia and osteoporosis in children with IBD.

Abstract
Dietary antigens may act as important stimuli of the mucosal immune system and have led to the study of nutritional therapy for IBD. Patients with active CD respond to bowel rest, along with total enteral nutrition or TPN. Bowel rest and TPN are as effective as corticosteroids at inducing remission for patients with active CD, although benefits are short-lived. Enteral nutrition is consistently less effective than conventional corticosteroids for treatment of active CD. Use of palatable, liquid polymeric diets in active CD is controversial, but these diets are of equal efficacy when compared with elemental diets. UC has not been treated effectively with either elemental diets or TPN. Fish oil contains n-3-PUFA, which inhibits production of proinflammatory cytokines and has some benefit in the treatment of CD. Topical applications of short-chain fatty acids have benefited diversion colitis and distal UC, whereas probiotics hold promise in the treatment of pouchitis.

Abstract
BACKGROUND AND AIMS Obesity is unusual in Crohn's disease and the particularities of the disease in obese patients have not been studied. METHODS 2065 patients were studied retrospectively. Obesity was defined by a BMI value >25.0 at disease onset and >30.0 at any time during the course of the disease. Disease characteristics, therapeutic needs, and year-by-year disease activity were determined in patients with and without obesity. RESULTS 62 patients (3%) were obese. When compared with non-obese patients, obese patients did not show differences regarding sex, intestinal disease location, and disease behavior, but at diagnosis they were older (32 vs 28 years, P = 0.01) and a larger proportion had anoperineal disease (35 vs 24%, P = 0.03). When the 62 obese patients were paired for sex, location of disease at onset, date of birth, and date of diagnosis with 124 non-obese patients, the disease severity assessed by the importance of medical therapy and excisional surgery did not differ in the two groups but time to development of anoperineal abscess or fistula was shorter in obese patients, and obese patients were more prone to develop an active disease (OR 1.50, 95% CI 1.07-2.11) and to require hospitalization (OR 2.35, 95% CI 1.56-3.52) CONCLUSION Obesity in Crohn's disease is associated with more frequent anoperineal complications and a more marked year-by-year disease activity, but does not alter significantly the long-term course of the disease.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a chronic inflammatory process, the aetiology of which remains unknown. Nutrition may play an important role in the pathogenesis and treatment of IBD. The evidence regarding the role of specific dietary components in the pathogenesis of IBD is still inconclusive. Many studies have been subject to methodological limitations; studies of better design are necessary to confirm the hypothesis that nutritional factors may indeed play a role in the development of IBD. Several studies have reported nutritional and functional deficiencies in IBD patients, especially in Crohn's disease. It is, however, hard to discriminate between disease-induced and malnutrition-induced changes in nutritional parameters. Maintaining adequate nutritional status has been suggested to be beneficial to the course of the disease in IBD. Studies have provided further insight into the possible beneficial effects of nutritional supplementation as primary and adjunctive therapy in IBD. The effects of specific nutritional therapy may be caused by alterations in intestinal flora and hence in the production of intraluminal proinflammatory substances. Immunonutrients such as n-3 fatty acids and antioxidants may also play a role in the treatment of IBD. In this paper, the relation between nutritional aetiological factors, nutritional status and nutritional therapy is discussed in detail.

Abstract
The nutritional impact of inflammatory bowel disease is notable, both in Crohn's disease and ulcerative colitis. The causes of malnutrition include decreased intake, maldigestion, malabsorption, accelerated nutrient losses, increased requirements, and drug-nutrient interactions. Inflammatory bowel disease causes alterations in body composition and, because of these changes, affects energy expenditure. Various approaches have been most effective in correcting malnutrition, supporting growth, and managing short-bowel syndrome, but the success of primary therapy has been limited.

Abstract
Although ulcerative colitis and Crohn's disease are relatively uncommon disorders, most primary care practices include a number of individuals with these diagnoses. Much of the initial evaluation and long-term care of these patients is managed or coordinated by their primary care physicians. A familiarity with current principles of diagnosis and treatment is essential. Ulcerative colitis and Crohn's disease are related, immunologically mediated disorders of unknown cause. Both are characterized by chronic relapsing courses, frequent need for surgical intervention, and increased colorectal cancer risk. Significant differences are seen between these two inflammatory bowel disease syndromes, in their histopathologic features, clinical manifestations, and response to treatment. This review focuses on the colorectal manifestations of inflammatory bowel disease, emphasizing clinical presentation, approach to diagnosis, medical and surgical management, and long-term prognosis.

Abstract
OBJECTIVE We conducted this study to evaluate the effect of disease localization on the anthropometric and metabolic characteristics of inactive Crohn's disease (CD). METHODS Forty-three patients with biopsy or radiology proven CD (23 men; age, 33.8 yr; range, 18-54 yr) in clinical remission (simplified Crohn's diseases activity index [SCDAI] < 3) and not receiving steroid therapy or nutritional support were enrolled in the study. Patients were separated into three subgroups according to disease localization: ileal (n = 16), ileo-colonic (n = 13), and colonic CD (n = 14). Sixty healthy volunteers (26 men; age, 32.0 yr; range, 18-60 yr), matched for age and height were used as control subjects. Body composition was assessed by both anthropometry and bioimpedance analysis and indirect calorimetry was performed to measure energy expenditure and substrate oxidation rates. RESULTS CD patients showed a lower body weight than controls, both as a whole (61.5 kg; range, 41.5-74.0 vs 66.9 kg; range, 55.0-86.0 kg; p < 0.001) and separated by disease localization (ileal; p < 0.001; ileo-colonic; p < 0.001; and colonic; p < 0.05 vs controls). Fat-free mass (FFM) did not differ between the groups, whereas fat mass was significantly lower in CD patients than in controls (p < 0.001), with the lowest values in ileal and ileo-colonic patients. Basal metabolic rate by kg of FFM was higher in CD patients than in healthy individuals (p < 0.01). Nonprotein respiratory quotient was significantly lower in CD than in controls as a whole (0.79; range, 0.73-0.84 vs 0.83; range, 0.79-0.89; p < 0.001) or separated by disease localization (p < 0.001 each subgroup vs controls), with a consequent higher lipid oxidation rate. A lower dietary lipid intake was found in patients than in controls (p < 0.01). CONCLUSIONS Regardless of disease localization, CD patients showed a lower fat mass and a higher utilization of lipids than control subjects. Patients with ileal and ileo-colonic disease showed the greater reduction in body weight, compared with control subjects, suggesting they were at a higher risk of malnutrition, probably as a consequence of the simultaneous occurrence of both malabsorption and decreased energy intake.

Abstract
OBJECTIVES To evaluate the anthropometric and metabolic characteristics of patients with Crohn's disease (CD) and ulcerative colitis (UC), comparing both groups with healthy volunteers. DESIGN A cross-sectional study. SETTING The Department of Internal Medicine, Catholic University Hospital, Rome, Italy. SUBJECTS Thirty-four patients with biopsy-proven inflammatory bowel disease (18 CD; 16 UC) in clinical remission (SCDAI < 3 and Powell-Tuck index < 4) not receiving steroid therapy. INTERVENTIONS All patients had a clinical examination. MAIN OUTCOME MEASURES Blood indicators of inflammation and nutritional status. Body composition was assessed by both anthropometry and bioimpedance and metabolic variables were measured by indirect calorimetry over a 60-90 min period. RESULTS CD had a lower body weight than both controls (58.1 kg, range 41.5-71.0 vs. 66.4 kg, range 57.0-76.0; P < 0.001) and UC) 58.1 kg, range 41.5-71.0 vs. 69.6 kg, range 50.5-94.0; (P < 0.001). Fat-free mass (FFM) did not differ between the groups, whilst fat mass was significantly lower in CD than in UC (P < 0.05) and controls (P < 0.001). Normalizing the basal metabolic rate by FFM, a higher value was found in CD compared with UC (143 kJ kg-1) d-(-1), range 97.5-179 vs. 133 kJ kg-1 d-1, range 123-148; P < 0.05) and control subject 143 kj kg-1 d-1, range 97.5-179 vs. 134 kj kg-1 d-1, range 122-162; P < 0.05). The nonprotein respiratory quotient was significantly lower in CD compared to UC 0.80, range 0.73-0.84 vs. 0.84, range 0.79-0.91; P < 0.01) and controls (0.80, range 0.73-0.84 vs. 0.83, range 0.81-0.87; P < 0.001), with a consequently higher lipid oxidation rate in CD. CONCLUSIONS CD subjects showed a decreased fat mass and enhanced utilization of lipids compared with UC and controls. These data could be explained by the larger intestinal involvement and considered as a contribution to lipid tissue wasting in CD.
