Home enteral nutrition does not decrease oral feeding in children during the first year of nutritional support

BACKGROUND

Enteral nutrition is necessary when nutritional status is poor and oral intake is insufficient or impossible. Although it has been suspected to reduce spontaneous oral feeding, no study has formally assessed the influence of enteral nutrition on pediatric oral intake. The present study aimed to evaluate variation in oral feeding intake after enteral nutrition initiation, and to identify factors influencing oral feeding.

METHODS

This retrospective cohort study included 149 pediatric patients from two French tertiary care hospitals, who received home enteral nutrition from 2009 to 2022. The patients were aged 2 months to 17 years (median age 3 years, interquartile range 1.3-9.2). Oral and enteral intakes were assessed when enteral nutrition was initiated (M0), and again at M3 (n = 123), M6 (n = 129), and M12 (n = 134) follow-ups, based on dieticians' and home services' reports. Oral feeding and body mass index z score variations during follow-ups were evaluated using a linear mixed regression model, including "time" as a fixed effect and "patient" as a random effect. Factors associated with oral feeding changes were assessed using a model interaction term.

RESULTS

Oral intake did not vary significantly (P = 0.99) over time and accounted for 47.4% ± 27.4%, 46.9% ± 27.4%, 48.4% ± 28.2%, and 46.6% ± 26.9% of the ideal recommended daily allowance (calculated for the ideal weight for height) at M0, M3, M6, and M12, respectively. Delivery method (nasogastric tube versus gastrostomy), prematurity, underlying disease, history of intrauterine growth retardation, and speech therapy intervention did not influence oral intake. Administration (i.e., exclusively continuous nocturnal infusion versus daytime bolus) led to different oral intake development, although oral intake also differed at M0.

CONCLUSIONS

Enteral nutrition, although increasing total energy intake, does not alter oral feeding during the first year of administration. Only the mode of administration might influence oral intake.

Natural History of Perianal Fistulising Lesions in Patients With Elderly-onset Crohn's Disease: A Population-based Study

INTRODUCTION

Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD.

METHOD

All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD.

RESULTS

A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up.

CONCLUSION

During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

Pharmacokinetics and safety of fluconazole and micafungin in neonates with systemic candidiasis: a randomized, open-label clinical trial

AIMS

The pharmacokinetics (PK) of fluconazole and micafungin differ in neonates compared with children and adults. Dosing instructions in product labels appear to be inconsistent with the emerging scientific evidence. Limited information is available on the safety profile of these agents in neonates. Our objective was to study the population PK and safety of both drugs, randomly administered in neonates with suspected or confirmed systemic candidiasis.

METHODS

Neonates were randomized 1:1 to fluconazole (loading dose 25 mg kg^-1 ; maintenance dose 12 mg kg^-1 day^-1 or 20 mg kg^-1 day^-1 , respectively, for infants <30 weeks or ≥30 weeks' corrected gestational age) or micafungin (loading dose 15 mg kg^-1 day^-1 ; maintenance dose 10 mg kg^-1 day^-1 ). PK samples were taken on treatment days 1 and 5. Population parameters were determined using NONMEM and Monte Carlo simulations performed to reach predefined targets. Clinical and laboratory data, and adverse events were collected up to 36 weeks' corrected gestational age or hospital discharge.

RESULTS

Thirty-six neonates were enrolled. The median (range) gestational age was 28.2 (24.1-40.1) and 26.8 (23.5-40.0) weeks for fluconazole and micafungin, respectively. Based on 163 PK samples, the median population clearance (l h^-1 kg^-1 ) and volume of distribution (l kg^-1 ) for fluconazole were: 0.015 [95% confidence interval (CI) 0.008, 0.039] and 0.913, and for micafungin were: 0.020 (95% CI 0.010, 0.023) and 0.354 (95% CI 0.225, 0.482), respectively. The loading dose was well tolerated. No adverse events associated with micafungin or fluconazole were reported.

CONCLUSION

Based on Monte Carlo simulations, a loading dose for fluconazole and dosing higher than recommended for both drugs are required to increase the area under the plasma drug concentration-time curve target attainment rate in neonates.

Dramatic Increase in Incidence of Ulcerative Colitis and Crohn's Disease (1988-2011): A Population-Based Study of French Adolescents

OBJECTIVES

Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period.

METHODS

Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification.

RESULTS

1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/10⁵ for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/10⁵ (+126%; P<0.001) and for UC, from 1.6 to 4.1/10⁵ (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC.

CONCLUSIONS

In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Extra-intestinal Manifestations at Diagnosis in Paediatric- and Elderly-onset Ulcerative Colitis are Associated With a More Severe Disease Outcome: A Population-based Study

BACKGROUND AND AIMS

Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome.

METHODS

Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected.

RESULTS

In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups.

CONCLUSIONS

Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.

[Neonatal management of a child exposed to tobacco smoke in utero]

The gravidic toxicity of the nicotinism on the fetus is now established. Certain long-term effects related to some substances, including certain unquestionable carcinogens, still remain to be evaluated. The risk of preterm birth is increased and the incidence of the intra-uterine growth retardation is high. Behavioral and physiological disorders, in particular metabolic, cardiac and respiratory disorders are observed from the first day of life. The risk of oro-facial malformations is not excluded. At mid-term the number of ORL and respiratory complications is higher and the risk of sudden infant death is almost doubled. The neonatale period should be used to assess the state of the newborn and to renew recommendations and advice for prevention. Breast feeding should and encouraged. This assessment also gives the mother an additional opportunity to reduce, to even cease smoking. A specialized consultation can be proposed if needed.

Identification of cross-reaction patterns in allergic contact dermatitis from topical corticosteroids

Contact allergy to topical corticosteroids occurs more frequently than previously supposed. Cross-allergic phenomena are common. On the basis of a review of the literature and our own patch test data on 15 patients, we conclude that positive patchtests to corticosteroids occur approximately six to seven times more frequently in well-defined groups of structurally-related substances than between corticosteroids of different groups. An analogous substitution pattern on the steroid D-ring or the carbon side chain (C20, C21) seems to have a significant influence on the association of positive patchtest results. This is not the case for other structural variables, such as the presence of a double bond in the steroid A-ring or fluoride substitutions on the B-ring. The effect of other factors such as concomitant sensitization and steroid metabolism in the skin on the development of a corticosteroid polyallergy are analysed, and the specificity and sensitivity of cross-allergy phenomena are evaluated. These are important in the selection of a topical steroid in the future treatment of a corticosteroid sensitive patient.

Silver polish: another source of contact dermatitis reactions to thiourea

A cleaning woman in a restaurant became sensitized to thiourea in a silver polish. The dermatitis persisted for several months and occasionally flared up after exposure to sunlight, even after she no longer used the product. Patch testing and photopatch testing showed that she had both contact and photocontact allergy.

Physicochemical studies on bovine eye lens proteins. II. Comparative physical study of the low-molecular-weight alpha-crystallins from calf lens cortical and nuclear fiber cells

The alpha L of cortical and nuclear fiber cells have been studied using hydrodynamical and physicochemical techniques. From the sedimentation and the diffusion coefficients in identical conditions, it can be concluded that alpha L,N is appreciably larger than alpha L,C but both have a similar structure in solution: a spherical particle with a high hydration. The alpha L,N not only contains several degraded alpha A- and alpha B-peptides but also a typical pattern of beta-peptides. The fluorescence spectrum indicates a shift of the hydrophobic tryptophan residues from a hydrophobic environment in alpha L,C to a more solvent-exposed and polar neighbourhood for alpha L,N. Also solubility studies on alpha L,C and alpha L,N in different solvent conditions and temperatures, indicate more apolar interactions between the peptides of the nuclear alpha L, than its cortical counterpart. The more hydrophobic interaction pattern of the peptides in alpha L,N can also be reconciled with a lower mean hydration potential, indicative of a higher hydrophobicity of the degraded alpha A-peptides.
