RESUMO

Critical illness is associated with a disturbed regulation of gastrointestinal hormones resulting in functional and metabolic anomalies. Fibroblast growth factor 19 (FGF19) is an ileum-derived metabolic hormone induced by bile salts upon gallbladder emptying after enteral nutrient stimulation. Our aim was to study the nutrient-stimulated FGF19 response in 24 patients admitted to the intensive care unit (ICU) compared with 12 healthy controls. All subjects received intraduodenal high-lipid nutrient infusion for 120 minutes. Blood was collected every 30 minutes until 1 hour after infusion, and gallbladder emptying was studied by ultrasound. Serum levels of bile salts and FGF19 were assessed. ICU patients had significantly higher fasting bile salt serum levels compared with controls, whereas FGF19 serum levels were similar. In both groups, nutrient infusion elicited substantial bile salt elevations (P < 0.001), peaking at 90 minutes, albeit with a significantly lower peak in the ICU patients (P = 0.029). In controls, FGF19 was significantly elevated relative to baseline from 120 minutes onward (P < 0.001). In ICU patients, the FGF19 response was blunted, as reflected by significantly lower FGF19 elevations at 120, 150, and 180 minutes (P < 0.05) and significantly lower area under the curve (AUC) values compared with controls (P < 0.001). Gallbladder dysmotility was associated with the impaired FGF19 response in critical illness. The gallbladder ejection fraction correlated positively with FGF19 AUC values (ρ = +0.34, P = 0.045). In 10 of 24 ICU patients, gallbladder emptying was disturbed. These patients had significantly lower FGF19 AUC values (P < 0.001). Gallbladder emptying and the FGF19 response were respectively disturbed or absent in patients receiving norepinephrine. Conclusion: The nutrient-stimulated FGF19 response is impaired in ICU patients, which is mechanistically linked to gallbladder dysmotility in critical illness. This may contribute to disturbed liver metabolism in these patients and has potential as a nutritional biomarker.

RESUMO

Age individuality is characterized by an imbalance of the molecular mechanisms of antioxidant defense in adolescents with arterial hypertension and biliary dyskinesia, as documented by an enzyme imbalance of the first line of antioxidant defense and H2O, accumulation, by a substantial increase in glutathione peroxidase activity, and by inhibition of the activity of glutathione-dependent enzymes. The considerable rise of 2,3-diphosphoglycerate suggests tissue hypoxia. With this, enhanced neutrophil elastase activity causes damage to the structural components of vascular wall connective tissue, resulting in the development of endothelial dysfunction.

RESUMO

BACKGROUND: Bioidentical hormones, including implanted estradiol-17beta pellets, have received considerable interest in the lay media. It is thought that parenteral estrogens have fewer gastrointestinal side effects than oral products. CASE: A 46-year-old woman in surgical menopause was transferred due to persistent abdominal pain and nausea after cholecystectomy in the setting of long-term hyperestrogenemia. She denied recent use of hormone therapy. Significant findings included biliary dyskinesia, hypertriglyceridemia and focal nodular hyperplasia of the liver with fatty infiltration. Laboratory findings were significant for hyperestrogenemia with markedly suppressed gonadotropin levels and undetectable inhibin level. The patient eventually disclosed receiving serial implants of estradiol-17beta and testosterone pellets by another provider. CONCLUSION: Serum levels from hormone pellets are unpredictable and can remain elevated for years. Lack of standardized dosing parameters for this nonregulated product likely contributes to the chance of hyperestrogenemia. Despite bypassing first-pass metabolism, supraphysiologic levels of these hormones can cause significant metabolic and gastrointestinal impairments.

RESUMO

BACKGROUND/AIMS: To investigate whether diabetics have altered gallbladder motility, and whether cisapride has any effect on gallbladder motility in these patients. The factors associated with abnormal gallbladder contractility, and with the effects of cisapride on gallbladder contractility in diabetics were also evaluated. METHODOLOGY: The gallbladder contractility parameters of 20 diabetics and 20 controls were assessed by real time ultrasonography. The same measurements were made after cisapride treatment in diabetics. RESULTS: Fasting gallbladder volume and residual gallbladder volume were statistically higher in the diabetic group than in the controls (P = 0.018 and P = 0.022, respectively). Multivariate analysis also showed a significant association between fasting gallbladder volume and existing diabetes (P = 0.0002). There was a significant positive correlation between level of hemoglobin A1c and fasting gallbladder volume (r = 0.48, P = 0.031). Responders to cisapride treatment had significantly higher hemoglobin A1c levels than nonresponders (6.6 +/- 1.3 vs. 9.1 +/- 1.8, respectively; P = 0.004). Logistic multiple regression analysis revealed that hemoglobin A1c level was the only independent factor that was predictive for efficacy of cisapride treatment. CONCLUSIONS: This study demonstrates that diabetics have impaired gallbladder contractility, and that control of diabetes is predictive for gallbladder contractility and response to cisapride therapy in these patients.

RESUMO

Experiments on 80 Wistar rats revealed the ability of Essentuki mineral waters to stimulate the reserves and sensitivity of the intestinal serotonin-producing system. A clinical trial on two groups of children (exposed to low-dose ionizing radiation or with posttraumatic astheno-neurotic syndrome) found out pronounced positive changes in the psychological status of the children which progressed in correlation with an increase of the blood serotonin levels.

RESUMO

The interrelationship between carotenemia and biliary dyskinesia was studied in eighty-two biliary dyskinesia patients and twenty-seven normal subjects. Incidence of serum carotene levels of more than 300 micrograms/dl was more frequent in biliary dyskinesia patients without liver damage or hyperlipemia. Among the carotenemia patients, no dietary cases were found, but metabolic and hyperlipemic ones were observed. Significant relationships were found between gall bladder contraction rate and the levels of serum carotene, vitamin A, and lipids in metabolic carotenemia. A close relationship between metabolic carotenemia and biliary dyskinesia was strongly suggested.

RESUMO

He-Ne laser irradiation of biologically active points and infrared laser irradiation of the liver were employed to improve gallbladder and sphincter functions, bile production and biochemistry, respectively, in a total of 57 patients with biliary dyskinesia presenting as hypokinetic dyskinesia of the gallbladder, hyperkinetic dyskinesia of the sphincter of Oddi or the combination of the two affections. Simultaneous use of the two kinds of laser irradiation appreciably shortens treatment duration, abolishes biliferous dysfunction, reestablishes physiological balance of bile components in case of its initial lithogenic potential.

RESUMO

Vasoactive intestinal polypeptide (VIP) has been postulated as a neuropeptide with inhibitory neurotransmitter activity in nonadrenergic noncholinergic pathways. Transcutaneous electric nerve stimulation (TENS) relaxes the lower esophageal sphincter in patients with achalasia. Such response is accompanied by a 30% increase in VIP concentrations in the systemic circulation. Since the sphincter of Oddi (SO) receives a very dense VIP nerve supply, we evaluate the effect of TENS on SO motor activity and on VIP plasma concentrations in patients with biliary dyskinesia and in healthy volunteers. TENS was performed with a pocket stimulator for 45 min. SO pressure and VIP levels were obtained before and after 45 min of TENS. In patients with SO dyskinesia, TENS produced a significant decrease in SO pressure from 80.1 +/- 11.9 mm Hg to 58.3 +/- 9.7 mm Hg p less than 0.01); this was accompanied by a significant increase in VIP plasma levels from 21.1 +/- 0.5 pg/ml to 32.6 +/- 1.5 pg/ml (p less than 0.01). In healthy volunteers, TENS did not produce significant changes in SO pressure. However, a significant increase in VIP plasma values was observed (p less than 0.01). No significant changes in amplitude, duration and frequency of SO phasic contractions were observed in either of the two groups evaluated. We conclude that, in patients with SO dyskinesia, TENS decreases SO basal pressure, possibly by a direct action of the released VIP in the systemic circulation. In healthy volunteers, TENS increases VIP plasma values without significant effect on SO basal pressure. These findings suggest that the response to TENS may be mediated by VIP. It is also possible that the alterations seen in patients with biliary dyskinesia may be due to impairment of the VIP nerve supply at the level of the SO.
