AbstractIn orally fed preterm infants, poor weight gain may be linked to low fecal pancreatic elastase-1 (FPE-1) activity, indicative of exocrine pancreatic insufficiency. The objective of this study was the retrospective assessment of the effect of exogenous digestive enzyme replacement by gavage in preterm infants with growth failure and low FPE-1 (<200 μg/g). We analyzed weight gain relative to baseline and caloric intake during 14-day periods before and after institution of digestive enzyme replacement containing 6000 U lipase and 240 U protease kg−1 d−1. Among 46 of 132 preterm infants < 1250g birth weight surviving to at least 14 days in whom FPE-1 was determined, 38 infants had low FPE-1 (< 200 μg/g), and 33 infants received exogenous digestive enzyme replacement. Average daily weight gain significantly increased from 14.4 [range 2.6–22.4] g kg−1 d−1 to 17.4 [8.4–29.0] g kg−1 d−1 (P = 0.001), as did weight gain per kcal, from 0.08 [0.02–0.13] g kcal−1 d−1 to 0.11 [0.05–0.18] g kcal−1 d−1.Conclusion: In preterm infants with signs and symptoms of exocrine pancreatic insufficiency, exogenous digestive enzyme replacement is associated with improved growth. What is Known:• Very preterm infants on full enteral nutrition may display growth failure linked to transient poor exocrine pancreatic function.• Porcine pancreatic enzymes covered with an acid-resistant coating are too large to pass the internal diameter of most gavage tubes used in very preterm infants.What is New:• Administration of a liquid formulation of acid-resistant microbial digestive enzymes in preterm infants with growth failure and low fecal pancreatic elastase-1 values was associated with improved weight gain.• Response to exogenous digestive enzyme replacement was associated with the prior extent of growth failure.

New Formulation

Background. Pancreatic enzyme replacement therapy is the standard of care for treatment of malabsorption in patients with cystic fibrosis (CF) and exocrine pancreatic insufficiency (PI).Aim. To evaluate efficacy and safety of a new formulation of pancrelipase (Ultrase MT20) in patients with CF and PI. Coefficients of fat absorption (CFA%) and nitrogen absorption (CNA%) were the main efficacy parameters. Safety was evaluated by monitoring laboratory analyses, adverse events (AEs), and overall signs and symptoms.Methods. Patients (n=31) were randomized in a crossover design comparing this pancrelipase with placebo during 2 inpatient evaluation periods (6-7 days each). Fat and protein/nitrogen ingestion and excretion were measured from food diaries and 72-hour stool collections. CFA% and CNA% were calculated for each period and compared.Results. Twenty-four patients provided analyzable data. This pancrelipase increased mean CFA% and CNA% (+34.7% and +25.7%, resp.,P<.0001for both), reduced stool frequency, and improved stool consistency compared with placebo. Placebo-treated patients reported more AEs, with gastrointestinal symptoms being the most frequently reported AE.Conclusions. This pancrelipase is a safe and effective treatment for malabsorption associated with exocrine PI in patients with CF.

The article presents a detailed review of the research results in the field of pancreatology published in 2018. Certain parts of the review are devoted to the pathogenesis, diagnostics, course of pancreatitis, its treatment, as well as autoimmune, hereditary pancreatitis, pancreatic pathology in children, as well as treatment. In studying the pathogenesis of pancreatitis, attention is paid to genetic markers of pancreatitis along with a role of bacterial overgrowth syndrome in the small intestine, both in terms of worsening of the course of pancreatitis and the lack of effectiveness of enzyme replacement therapy. The study of the role of alcohol abuse and smoking in the pathogenesis of pancreatic pathology is still in progress. Diagnostics is going on. Endosonography remains the most informative method. A number of studies have been devoted to the studying of exocrine and endocrine pancreatic insufficiency both upon pancreatitis, pancreatic tumors, and in functional dyspepsia and HIV infection. Autoimmune pancreatitis is increasingly being diagnosed, a number of studies are devoted to its diagnostics and treatment. Pancreatic diseases in children develop mainly on the background of genetic predisposition, while functional pancreatic insufficiency occurs in adult patients. The study of the peculiarities of the effect of enzyme replacement therapy continues. The immediate and remote results of the surgical treatment of pancreatic pathology are assessed.

Exocrine pancreatic insufficiency (EPI) is defined as the maldigestion of foods due to inadequate pancreatic secretion, which can be caused by alterations in its stimulation, production, transport, or interaction with nutrients at duodenal level. The most frequent causes are chronic pancreatitis in adults and cystic fibrosis in children. The prevalence of EPI is high, varying according to its etiology, but it is considered to be underdiagnosed and undertreated. Its importance lies in the quality of life impairment that results from the malabsorption and malnutrition and in the increased morbidity and mortality, being associated with osteoporosis and cardiovascular events. The diagnosis is based on a set of symptoms, indicators of malnutrition, and an indirect non-invasive test in at-risk patients. The treatment of choice combines non-restrictive dietary measures with pancreatic enzyme replacement therapy to correct the associated symptoms and improve the nutritional status of patients. Non-responders require the adjustment of pancreatic enzyme therapy, the association of proton pump inhibitors, and/or the evaluation of alternative diagnoses such as bacterial overgrowth. This review offers an in-depth overview of EPI in order to support the proper management of this entity based on updated and integrated knowledge of its etiopathogenesis, prevalence, diagnosis, and treatment.

A 14-year-old child treated with valproic acid over several years for a seizure disorder developed abdominal pain with radiological evidence of acute pancreatitis. The association with valproic acid was not recognized, and the child continued to take the drug. The patient eventually developed steatorrhea and weight loss that improved with pancreatic enzyme replacement. Radiological evaluation showed an atrophic pancreas. Without evidence of other etiological factors, valproic acid by itself appeared to be the cause of chronic pancreatitis with exocrine pancreatic insufficiency in this patient.

Immunoreactive Elastase

Abstract We have evaluated the diagnostic value of the fecal elastase test in comparison with the secretin-pancreozymin test in the diagnosis of exocrine pancreatic insufficiency. Pancreatic elastase was measured immunologically. Immunoreactive elastase activity in spot stools from controls ranged from 136 to 4440 microgram/g; 95% of all values were within 175 to 1500 microgram/g. The elastase assay CVs ranged from 3.3% to 6.3% (intraassay) and from 4.1% to 10.2% (interassay). The output of elastase correlated well with those of amylase, lipase, and trypsin, yielding respective correlation coefficients of 0.83, 0.82, and 0.84 in controls and 0.86, 0.91, and 0.91 in patients with impaired pancreatic function. In contrast to fecal chymotrypsin, the test results were unaffected by pancreatic enzyme replacement therapy. These results indicate that fecal immunoreactive elastase may be recommended as a new, noninvasive tubeless test of pancreatic function.
