Therapeutic role of kaempferol and myricetin in streptozotocin-induced diabetes synergistically via modulation in pancreatic amylase, glycogen storage and insulin secretion.

Kaempferol and Myricetin alone have promising benefits on diabetes and related complications, yet the effectiveness of cotreating the two compounds on diabetes have not been studied. The existing investigation was to study the combined anti-diabetic effect of kaempferol and myricetin in Streptozotocin (STZ)-activated diabetes in rats. To evaluate the anti-diabetic activity, 36 Wistar rats were segregated into six groups; Normal, 50 mg/kg STZ-induced diabetes, and four (50 mg/kg kaempferol, 50 mg/kg myricetin, 25 mg/kg kaempferol + myricetin, and 5 mg/kg glibenclamide) compound-treated diabetic groups. The effects of co-treatment on parameters, glucose, insulin, lipid profile, liver enzymes, antioxidant biomarkers, and inflammatory cytokines were measured. The study revealed that combined treatment restored the assessed parameters including glucose levels, inflammatory cytokines, oxidative markers, and lipid and liver enzymes in diabetic rats. The results indicate that cotreatment of kaempferol and myricetin has a beneficial role against diabetes suggesting that cotreatment of these compounds can be used therapeutically in treating diabetes.

[Diffuse large B-cell lymphoma complicated with pancreatic fistula and peritonitis following initial chemotherapy].

A 59-year-old-woman complained of weight loss and abdominal pain. A CT scan revealed a 20 cm large retroperitoneal mass, and she was diagnosed with diffuse large B-cell lymphoma via biopsy of the mass. After 75% CHP therapy, she developed an acute abdomen and CT revealed generalized peritonitis. Amylase in the ascites fluid was elevated, and infiltration into the pancreas was suspected on CT before treatment, suggesting a pancreatic fistula caused by tumor shrinkage. Enterobacteria were found in ascites fluid culture, suggesting a gastrointestinal perforation complication. The patient was refractory to treatment, and death was confirmed due to progression of the primary disease. The pathological autopsy revealed diffuse pancreatic infiltration, suggesting that the pancreatic fistula was caused by pancreatic injury. Pancreatic fistula is a known complication of surgical procedures but is rarely caused by tumor shrinkage due to chemotherapy. Since there is no preventive method for pancreatic injury caused by tumor shrinkage, early diagnosis and early treatment of pancreatic fistula are critical, and ascites fluid analysis, including amylase, was thought to be useful for the diagnosis.

[A case of lung adenocarcinoma with markedly elevated amylase in airway secretions].

A 45-year-old male patient was admitted to the hospital because of intermittent cough and expectoration for more than 1 year, worsened by dyspnea for 2 months, and was finally diagnosed with lung adenocarcinoma. The CT scan of the chest revealed lesions of diversity with fibrosis, mass and effusion, but his severe cough limited biopsy of the lesions. The difficult process of diagnosis was aided by the further analysis of the sputum, which showed significantly elevated amylase without any evidence of pancreatic disease. The cough was relieved by intravenous pumping octreotide acetate, and both CT-guided lung biopsy and transbronchial biopsy revealed the lung adenocarcinoma. The diagnostic process of this case provided a helpful diagnostic thinking and demonstrated the rare clinical features of lung adenocarcinoma.

Study of the gastrointestinal bioavailability of a pancreatic extract product (Zenpep) in chronic pancreatitis patients with exocrine pancreatic insufficiency.

INTRODUCTION: The Food and Drug Administration in 2006 required that all pancreatic enzyme products demonstrate bioavailability of lipase, amylase, and protease in the proximal small intestine. METHODS: In this phase I open-label, randomized, crossover trial, 17 adult chronic pancreatitis (CP) patients with severe exocrine pancreatic insufficiency (EPI) underwent two separate gastroduodenal perfusion procedures (Dreiling tube suctioning and [14C]-PEG instillation by an attached Dobhoff tube in the duodenal bulb). Patients received Ensure Plus® alone and Ensure Plus with Zenpep (75,000 USP lipase units) in random order. The bioavailability of Zenpep was estimated by comparing the recovery of lipase, amylase, chymotrypsin activity in two treatment conditions. 14C-PEG was used to correct duodenal aspirates volume. The primary efficacy endpoint was lipase delivery in the duodenum after Zenpep administration under fed conditions. Secondary efficacy endpoints included chymotrypsin and amylase delivery, serum CCK levels, and measuring duodenal and gastric pH. RESULTS: Zenpep administration with a test meal was associated with significant increase in duodenal aspiration of lipase (p = 0.046), chymotrypsin (p = 0.008), and amylase (p = 0.001), compared to the test meal alone, indicating release of enzymes to the duodenum. Lipase delivery was higher in the pH subpopulation (the efficacy population with acid hypersecretors excluded) (p = 0.01). Recovery of [14C]-PEG was 61%. Zenpep was generally well tolerated. All adverse events were mild and transient. CONCLUSIONS: In CP patients with severe EPI, lipase, chymotrypsin and amylase were released rapidly into the duodenum after ingestion of Zenpep plus meal compared to meals alone. Results also reflected the known pH threshold for enzyme release from enteric coated products.

[DELAYED RESULTS OF ENZYME REPLACEMENT THERAPY, PRESCRIBED BY RESULTS OF 13C-TRIGLYCERIDE BREATH TEST].

Maldigestion persists in most patients with chronic pancreatitis (CP). The objective lipase and amylase insufficiency diagnosis is needed to achieve an adequate clinical response to oral pancreatic enzyme substitution therapy. The novel data is presented in the article about the role of 13C-mixed triglyceride breath test as a tool for exocrine pancreatic insufficiency diagnosis, for evaluating fat malabsorbtion in CP patients. 135 patients were included in the investigation. Delayed results of enzyme replacement therapy were estimated after 1 and 2 year of surveillance. It has been shown, that partial recovery of exocrine pancreatic function is possible, and replacement therapy leads to patients nutritional status improving. Thus 13C-triglyceride breath test could be useful tool in clinical practice for CP diagnosis. The test make it possible to choose the initial pancreatic enzyme dosage and are beneficial during the treatment for pancreatic enzyme dose correction.

The effect of oral pancreatic enzyme supplementation on the course and outcome of acute pancreatitis: a randomized, double-blind parallel-group study.

CONTEXT: Pancreatic exocrine insufficiency is a significant problem after acute pancreatitis. OBJECTIVE: To evaluate whether oral pancreatic enzyme supplementation improves the recovery of pancreatic exocrine function and to explore the efficacy, safety and tolerability of pancreatic enzyme supplementation in patients during the refeeding period after acute pancreatitis. DESIGN: Prospective double-blind, placebo controlled, randomized study. PATIENTS: The sudy included 56 patients with acute pancreatitis. MAIN OUTCOME MEASURES: Primary efficacy variable was recovery from pancreatic exocrine insufficiency. Secondary objectives were body weight, abdominal pain, course of APACHE II score, patient's symptoms and quality of life. RESULTS: Twenty of the 56 patients showed low fecal elastase values indicating pancreatic exocrine insufficiency after acute pancreatitis. Median time to recovery from exocrine pancreatic insufficiency was 14 days in the enzyme supplementation group and 23 days in the placebo group but overall differences for primary and all but one secondary endpoint did not reach statistical significance. However, a positive tendency in favour of enzyme supplementation was found for quality of life parameters (FACT-Pa) in all subscores. There were no relevant differences between placebo and oral pancreatic enzyme supplementation detected with respect to safety and tolerability. CONCLUSION: Enzyme supplementation positively effects the course of acute pancreatitis if administered during the early refeeding phase after acute pancreatitis. There is evidence that oral pancreatic enzyme supplementation has a positive impact on the course of the disease and the global health status (less weight loss, less flatulence, improved quality of life). Oral pancreatic enzyme supplementation was safely administered and can be added to the treatment regimen of patients in a refeeding status after severe acute pancreatitis.

[The clinical application of 13C-breath tests in pancreatic diseases].

Maldigestion persists in most patients with chronic pancreatitis (GP). The objective lipase and amylase insufficiency diagnosis is needed to achieve an adequate clinical response to oral pancreatic enzyme substitution therapy. The novel data is presented in the article about the role of 13C-mixed triglyceride and 13C-corn starch breath tests as a tools for exocrine pancreatic insufficiency diagnosis, for evaluating fat and starch malabsorbtion in CP patients. 135 patients were included in the investigation. It has been shown, that 13C-breath tests could be useful tools in clinical practice for CP diagnosis. They are well correlate with fecal elastase-1 level, has high sensitivity and specificity for diagnosis of lipase and amylase deficiency. Tests make it possible to choose the initial pancreatic enzyme dosage and are beneficial during the treatment for pancreatic enzyme dose correction.

Salivary Amylase-Responsive Buccal Tablets Wipe Out Chemotherapy-Rooted Refractory Oral Mucositis.

Oral mucositis (OM) is the most common and refractory complication of cancer chemotherapy and radiotherapy, severely affecting patients' life quality, lowering treatment tolerance, and discouraging patient compliance. Current OM delivery systems mostly affect the comfort of patient use and lead to poor compliance and unsatisfactory effects. Herein, salivary amylases (SAs)-responsive buccal tablets consisting of porous manganese-substituted Prussian blue (PMPB) nanocubes (NCs), anti-inflammatory apremilast (Apr) and starch controller have been engineered. PMPB NCs with large surface area can serve as carriers to load Apr, and their multienzyme-mimicking activity enables them to scavenge reactive oxygen species (ROS), which thus synergize with Apr to mitigate inflammation. More significantly, the starch controller can respond to abundant SAs in the oral cavity and realize the cascade, continuous, and complete drug release after enzymatic decomposition, which not only aids with high tissue affinity to prolong the resistance time but also improves the comfort of use. The preclinical study reveals that contributed by the above actions, such buccal tablets mitigate inflammation, promote endothelium proliferation and migration, and accelerate wound healing for repressing chemotherapy-originated intractable OM with positive oral microenvironment and shorter recovery time, thus holding high potentials in clinical translation.

Liprotamase long-term safety and support of nutritional status in pancreatic-insufficient cystic fibrosis.

OBJECTIVES: Patients with cystic fibrosis (CF) who have exocrine pancreatic insufficiency (EPI) require treatment with pancreatic enzyme replacement therapy (PERT) to maintain adequate nutrition and age-appropriate growth and weight gain. Liprotamase, a nonporcine, highly purified biotechnology-derived PERT, has demonstrated significant efficacy in fat and protein malabsorption in patients with EPI compared to placebo. This study of liprotamase is the first ever long-term trial of a PERT to evaluate safety and nutritional parameters. METHODS: This phase III 12-month open-label trial assessed the safety, tolerability, and long-term nutritional effects of liprotamase treatment in patients with CF and EPI 7 years and older. All of the patients were required to discontinue their long-term use of porcine PERTs at the time of enrollment. Dosing started at 1 capsule of liprotamase (32,500 US Pharmacopoeia (USP) units crystallized cross-linked lipase, 25,000 USP units crystallized protease, and 3,750 USP units amorphous amylase) per meal or snack; dose could be increased based on protocol-defined parameters. RESULTS: A total of 215 subjects were enrolled and 214 received at least 1 dose of liprotamase (mean 5.5 capsules per day). During the study period, height, weight, and body mass index z scores and lung function as measured by forced expiratory volume in 1 second were stable. There were no clinically meaningful changes in laboratory tests, including levels of fat-soluble vitamins. Liprotamase was well tolerated without any significant safety concerns. Adverse events, primarily gastrointestinal, led to treatment discontinuation for 36 subjects (16.8%), most within the first 3 months. CONCLUSIONS: Treatment with a mean of 5.5 capsules of liprotamase per day, during meals and snacks, for up to 12 months was safe, well tolerated, and associated with age-appropriate growth and weight gain or weight maintenance in subjects with CF-related EPI.

Identification of novel immune-related targets mediating disease progression in acute pancreatitis.

Introduction: Acute pancreatitis (AP) is an inflammatory disease with very poor outcomes. However, the order of induction and coordinated interactions of systemic inflammatory response syndrome (SIRS) and compensatory anti-inflammatory response syndrome (CARS) and the potential mechanisms in AP are still unclear. Methods: An integrative analysis was performed based on transcripts of blood from patients with different severity levels of AP (GSE194331), as well as impaired lung (GSE151572), liver (GSE151927) and pancreas (GSE65146) samples from an AP experimental model to identify inflammatory signals and immune response-associated susceptibility genes. An AP animal model was established in wild-type (WT) mice and Tlr2-deficient mice by repeated intraperitoneal injection of cerulein. Serum lipase and amylase, pancreas impairment and neutrophil infiltration were evaluated to assess the effects of Tlr2 in vivo. Results: The numbers of anti-inflammatory response-related cells, such as M2 macrophages (P = 3.2 × 10-3), were increased with worsening AP progression, while the numbers of pro-inflammatory response-related cells, such as neutrophils (P = 3.0 × 10-8), also increased. Then, 10 immune-related AP susceptibility genes (SOSC3, ITGAM, CAMP, FPR1, IL1R1, TLR2, S100A8/9, HK3 and MMP9) were identified. Finally, compared with WT mice, Tlr2-deficient mice exhibited not only significantly reduced serum lipase and amylase levels after cerulein induction but also alleviated pancreatic inflammation and neutrophil accumulation. Discussion: In summary, we discovered SIRS and CARS were stimulated in parallel, not activated consecutively. In addition, among the novel susceptibility genes, TLR2might be a novel therapeutic target that mediates dysregulation of inflammatory responses during AP progression.

Bifidobacterium spp. and their metabolite lactate protect against acute pancreatitis via inhibition of pancreatic and systemic inflammatory responses.

Severe acute pancreatitis (SAP) is a critical illness characterized by a severe systemic inflammatory response resulting in persistent multiple organ failure and sepsis. The intestinal microbiome is increasingly appreciated to play a crucial role in modulation of AP disease outcome, but limited information is available about the identity and mechanism of action for specific commensal bacteria involved in AP-associated inflammation. Here we show that Bifidobacteria, particularly B. animalis, can protect against AP by regulating pancreatic and systemic inflammation in germ-free (GF) and oral antibiotic-treated (Abx) mouse models. Colonization by B. animalis and administration of its metabolite lactate protected Abx and GF mice from AP by reducing serum amylase concentration, ameliorating pancreatic lesions and improving survival rate after retrograde injection of sodium taurocholate. B. animalis relieved macrophage-associated local and systemic inflammation of AP in a TLR4/MyD88- and NLRP3/Caspase1-dependent manner through its metabolite lactate. Supporting our findings from the mouse study, clinical AP patients exhibited a decreased fecal abundance of Bifidobacteria that was inversely correlated with the severity of systemic inflammatory responses. These results may shed light on the heterogeneity of clinical outcomes and drive the development of more efficacious therapeutic interventions for AP, and potentially for other inflammatory disorders.

Pancreatic enzyme supplementation.

PURPOSE OF REVIEW: In 2010, the Food and Drug Administration required manufacturers of pancreatic enzymes replacement therapy (PERT) to have approval for marketing, rescinding the distribution of PERT that had been available for decades without definitive studies of efficacy and safety. Therefore, many patients on PERT had to change preparation in the last year and be placed on new formulations of PERT or switched to a new branded product altogether. This review summarizes the clinical data on these new products and reviews their general use. RECENT FINDINGS: The three new commercially available PERTs all demonstrated similar (as good as or slightly improved) abilities to increase the absorption of fat and nitrogen compared with previous PERT preparations. All preparations tests demonstrated superiority over placebo-controlled portions of the clinical trials. Side-effects seem to be no different compared with placebo. Additional PERTs are being evaluated including a nonporcine preparation which may be available in the future. SUMMARY: These new preparations, Creon, Zenpep, and Pancreaze, demonstrated improvement in the absorption of fat and nitrogen in patients with pancreatic insufficiency related to cystic fibrosis. Some patient variability to response continues, so clinicians need to continue to titrate dose and preparations based on weight gain and patient response.

Improvement in serum amylase and glucose levels in diabetic rats on oral administration of bisdemethoxycurcumin from Curcuma longa and limonoids from Azadirachta indica.

Curcuma longa and Azadirachta indica are traditionally used in Indian cuisine and Ayurvedic medicine as nutraceuticals against diabetes. The crude C. longa isopropanol extract, bisdemethoxycurcumin (BDMC), the purified bioactive component from C. longa, and limonoids azadiradione, gedunin from A. indica, are able to inhibit in vitro the antidiabetic target human pancreatic α-amylase independently. However, no reports on their in vivo efficacy in animal models exist. Thus, the antidiabetic effect of these orally administered human pancreatic α-amylase inhibitors was performed on streptozotocin-induced Sprague-Dawley rats. Initially, the normal rats were treated with test compounds (10-100 mg/kg of body weight) in corn oil (5 ml/kg), and as no lethality was observed in these doses, further studies were carried out with lowest concentration of 10 mg/kg of body weight. A reduction in area under curve (AUC) suggested glucose-lowering effect of these compounds in starch fed diabetic rats. The efficacy study showed a significant improvement in body weight, blood glucose levels, serum amylase, and fructosamine levels as well in other serum parameters associated with diabetes with respect to liver and renal functions. Hence, under in vivo conditions, inhibition of α-amylase activity by BDMC and limonoids affirms it as one of the mechanisms of action resulting in reduction of blood glucose levels. PRACTICAL APPLICATIONS: Bisdemethoxycurcumin from C. longa and limonoids, namely, azadiradione and gedunin, from A. indica are potent inhibitors of the antidiabetic target human pancreatic α-amylase. Oral Starch Tolerance Test (OSTT) and 28-day efficacy study to check the effect of these orally administered inhibitors in diabetic rat models showed significant improvements in serum blood glucose and amylase levels as well as in other diabetes related serum parameters, namely, bilirubin, lipids, lactate dehydrogenase, alkaline phosphatase, and urea. The study contributes to understanding the action and efficacy of these pancreatic α-amylase inhibitors and suggests a potential role for them as nutraceuticals/therapeutics in management of post-prandial hyperglycemia.

Plasma concentrations of neurotensin and CCK in patients with chronic pancreatitis with and without enzyme substitution.

The peptide hormones neurotensin (NT) and cholecystokinin (CCK) are commonly attributed with a physiological role in the stimulation of exocrine pancreatic secretion. However, on the other hand, little is known about the effect of diminished exocrine pancreatic function and of the resulting maldigestion on postprandial plasma levels of these two gastrointestinal peptides. We investigated, therefore, the effect of enzyme substitution therapy on the magnitude and time course of plasma concentrations of both hormones in patients suffering from severe chronic pancreatitis. Pancreatic insufficiency led to elevated NT-concentrations, in response to a standard meal, which could be reduced by enzyme replacement therapy. Prior to enzyme therapy, the mean integrated postprandial release of NT amounted to 2800 +/- 250 pg/ml after 60 min in patients with severe chronic pancreatitis. This amount was significantly reduced to 1250 +/- 150 pg/ml after 60 min after enzyme therapy, compared to 810 +/- 90 pg/ml after 60 min in healthy volunteers after the standard meal. The integrated postprandial CCK level in patients investigated was significantly lower (35 +/- 4.8 pmol/L after 60 min) without any substitution therapy, compared to the integrated peptide amount in healthy volunteers (145 +/- 13.5 pmol/L after 60 min). Enzyme therapy in patients suffering from chronic pancreatitis led to an increased postprandial CCK-level (80 +/- 9.6 pmol/L after 60 min). Elevated CCK-plasma concentrations have not been demonstrated in these patients with pancreatic insufficiency. We therefore suggest that CCK might not play a major role in feedback regulation in patients with chronic pancreatitis. However, in light of elevated NT plasma concentrations in patients with chronic pancreatitis, NT-mediated influence on the pancreas deserves further study.

The effect of pancreatic enzyme supplementation in patients with steatorrhoea after total gastrectomy.

OBJECTIVE: To assess the influence of pancreatic enzyme supplementation on symptoms, energy intake, bowel habits, and fat malassimilation in patients after total gastrectomy. DESIGN: A prospective, double-blind, randomized, parallel, placebo-controlled, multi-centre trial. SETTING: Institutionalized patients in three gastroenterological rehabilitation clinics. PARTICIPANTS: 52 institutionalized patients with a faecal fat output > or = 14 g/day, operated on for malignant gastric disease a median of 198 days (interquartile range (IQR) 47-608) previously, and free from recurrence and/or metastasis. INTERVENTIONS: Nine sachets of pancreatic enzymes per day (each containing lipase 36,000, amylase 27,000, protease 2400 FIP (Federation International Pharmaceutique)) or identical-looking placebo were given for 14 days. MAIN OUTCOME MEASURES: Abdominal symptoms, energy intake, bowel habits and fat malassimilation. RESULTS: After treatment, patients on enzyme therapy felt better overall (P = 0.006), but no improvement of a specific symptom could be identified. During the intervention, the median kilojoule intake per kilogram body weight was 9% higher in the placebo group (170.8 (IQR 146.9-202.6)) than in the enzyme-treated group (157.0 (IQR 134.8-170.4)) (P = 0.03). Enzyme treatment did not result in a significant difference between the placebo and the enzyme-treated group regarding bowel habits or fat malassimilation. CONCLUSIONS: The effect of high-dose pancreatic enzymes supplementation on symptoms and steatorrhoea after total gastrectomy is marginal and does not justify its routine use.

Quality of life assessment after pancreatic enzyme replacement therapy in chronic pancreatitis.

GOALS: To evaluate the quality of life (QoL) of patients with chronic pancreatitis before and after pancreatic enzyme replacement therapy in a prospective, multicentre, follow-up study. STUDY: Two groups of patients were evaluated. Group 1 consisted of 31 patients with newly diagnosed chronic pancreatitis who had never been treated with pancreatic enzyme preparations. Group 2 consisted of 39 patients whose disease was diagnosed on average 3.4 years before the start of the study. The latter group of patients had undergone pancreatic enzyme replacement therapy, but during follow-up this treatment proved to be insufficient. The dose of pancreatic enzyme replacement therapy was tailored in accordance with the degree of pancreatic exocrine insufficiency measured by means of exocrine pancreatic function tests. A modified European Organizaton for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) was used to assess QoL. RESULTS: The social functioning and financial strain were significantly better, while the levels of hope and confidence were significantly reduced in group 1 compared with group 2. A significant gain in body weight and a significantly reduced defecation rate were found in both groups one month after the beginning of the pancreatic enzyme replacement therapy when compared with the pretreatment values. The prevalence of general and disease-specific symptoms and the intensity of pain were reduced in both groups after one month of enzyme substitution therapy. The working ability, the financial strain and the overall QoL scores were improved significantly in both groups, while the cognitive functioning score was found to be significantly improved during the follow-up only in group 1. The overall increase in the QoL score correlated significantly with the increase in body weight and the decrease in defecation number in both groups. CONCLUSIONS: Pancreatic enzyme replacement therapy in patients with chronic pancreatitis not only reduced the extent of steatorrhea and pain, but also significantly improved a variety of other symptoms and the patient's QoL. Individually tailored enzyme replacement therapy improved the QoL not only in the untreated chronic pancreatitis patients, but also in the inadequately treated group. This study demonstrated that the EORTC QLQ-C30 questionnaire, with the addition of two further questions about steatorrhea, is a useful tool for the evaluation of QoL in patients with chronic pancreatitis.

Pancreatic enzyme replacement therapy: comparative effects of conventional and enteric-coated microspheric pancreatin and acid-stable fungal enzyme preparations on steatorrhoea in chronic pancreatitis.

The therapeutic effectiveness of a conventional (Pankreon-Granulat) and an acid-protected (Kreon) porcine pancreatic enzyme preparation, and an acid-stable fungal enzyme preparation (Nortase) in the treatment of severe pancreatogenic steatorrhoea was investigated. The study comprised 17 patients with chronic pancreatitis and exocrine pancreatic insufficiency with (A) or without (B) a previous Whipple's procedure (B II resection + partial duodenopancreatectomy). With all three enzyme preparations, a significant (p less than 0.05) reduction in the total faecal fat excretion/day was achieved. In therapy group A, this reduction was, on average, 58% for Kreon (100,000 U lipase/day), 67% for Pankreon-Granulat (360,000 U lipase/day) and 54% for Nortase (75,000 U lipase/day), the respective figures for therapy group B being 58%, 52% and 46% at identical dosages. Thus, in both groups, the effect produced by the conventional porcine pancreatic enzyme preparation and the acid-protected porcine or the acid-stable fungal enzyme preparation was largely equivalent, although the latter two preparations were administered at only 1/4 of the dosages of the former preparation. On the basis of the respective average reduction in total faecal fat excretion and average number of stools/day, it would appear that in patients with chronic pancreatitis and prior Whipple's procedure, Pankreon-Granulat should be administered for enzyme replacement while in patients with an intact upper gastrointestinal tract, Kreon should be administered, in the treatment of steatorrhoea in chronic pancreatitis.

[Therapeutic effect of a pharmacologic combination of choleretics and digestive enzymes in exocrine pancreatic insufficiency]. / Sull'effetto terapeutico di una associazione farmacologica a base di coleretici ed enzimi digestivi nell'insufficienza pancreatica esocrina

Phosphorylcholine and homocysteine have an important choleretic action and also potentiate exocrine pancreatic secretion by way of stimulation and a more effective preparation of the substrate against attack by lipolytic enzymes. The protection offered by pancreatic enzymes in the correction of the digestive insufficiency in the endoluminal stage is also known. An analysis was therefore made of the action of an association of phosphorylcholine homocysteine and digestive enzymes in cases of exocrine pancreatic insufficiency and primary or secondary malabsorption. This action was evaluated on the basis of the reduction of elimination of steatorrhoea. For this purpose, faecal lipids were determined with the method proposed by van de Kramer et al. The most significant results were obtained in cases where digestive insufficiency was most marked, where correction of the pancreatic enzyme deficiency and improved biliary function were particularly required.

[Steatorrhea and its treatment with pancreatic enzymes in endocrine tumors of the pancreas (pancreatic adenomas)]. / Esteatorrea y su tratamiento con fermentos pancreáticos en los tumores endocrinos del páncreas (apudomas pancreáticos).

We report the treatment of steatorrhea with pancreatic enzymes in four pancreatic endocrine tumors treated in our hospital. All four patients were males, with a mean age of 50 +/- 4.6, a basal steatorrhea of 10.8 +/- 3.7 g/24 h (N: less than 5 g/24 h), and a defecation rate of 1.8 +/- 0.8 (mean +/- SD). They were treated for one week with Pankreon 700 in the form of pills of 700 mg pancreatin (28,000 U lipase PIF, 22,000 U amylase PIF and 1,500 U protease PIF). They were given 15 pills/day divided into three doses. The mean steatorrhea dropped to 7.1 +/- 1.5 g/24 h. Then the patients were given Creon capsules with 300 mg pancreatin in pellets (8,000 U lipase PIF, 9,000 U amylase PIF and 450 U protease PIF). They were given six capsules/day divided into three doses, and the steatorrhea dropped to 7.2 +/- 4.1 g/24 h, while the rate of defecation dropped to 1/day. On comparison of the two products (Pankreon-- a classic form of pancreatin, and Creon-- a modern galenical in pellets), it was found that Creon achieved the same results as Pankreon 700 in a doses 2.5 times lower. This pilot study demonstrates that exocrine pancreatic insufficiency can be frequent in endocrine tumors of the pancreas, and although underestimated, it can be partially corrected with pancreatic enzymes.

Pancreatic enzyme supplementation in normal and exocrine pancreatic insufficient pigs.

The effect of pancreatic enzyme preparation (Combizyme Forte granulate) on the growth rate of normal, sham-operated and pancreatic duct ligated growing pigs was studied in 2 trials. In the first trial 6 normal Yorkshire pigs were fed a pancreatic enzyme supplement and 6 other pigs from the same litter were fed without supplementation. The growth rate over a period of 4 weeks was not significantly greater in the supplemented group. In a second trial exocrine pancreatic insufficiency, without diabetic symptoms, was produced in 12 pigs (aged 1.5 months and weighing 14 kgs) by ligation of the main pancreatic duct. The growth rates over a period of 20 days after surgery were 240 g, 454 g and 483 g/day in ligated pigs, in ligated pigs supplemented with pancreatic enzyme and in sham-operated control pigs, respectively. The difference between the ligated groups was significant (p less than 0.01) indicating the efficiency of the pancreatic enzyme therapy.
