Abstract

Item does not contain fulltext, BACKGROUND AND AIMS: The case-mix of patients with intestinal failure due to short bowel syndrome (SBS-IF) can differ among centres and may also be affected by the timeframe of data collection. Therefore, the ESPEN international multicenter cross-sectional survey was analyzed to compare the characteristics of SBS-IF cohorts collected within the same timeframe in different countries. METHODS: The study included 1880 adult SBS-IF patients collected in 2015 by 65 centres from 22 countries. The demographic, nutritional, SBS type (end jejunostomy, SBS-J; jejuno-colic anastomosis, SBS-JC; jejunoileal anastomosis with an intact colon and ileocecal valve, SBS-JIC), underlying disease and intravenous supplementation (IVS) characteristics were analyzed. IVS was classified as fluid and electrolyte alone (FE) or parenteral nutrition admixture (PN). The mean daily IVS volume, calculated on a weekly basis, was categorized as <1, 1-2, 2-3 and >3 L/day. RESULTS: In the entire group: 60.7% were females and SBS-J comprised 60% of cases, while mesenteric ischaemia (MI) and Crohn' disease (CD) were the main underlying diseases. IVS dependency was longer than 3 years in around 50% of cases; IVS was infused ≥5 days/week in 75% and FE in 10% of cases. Within the SBS-IF cohort: CD was twice and thrice more frequent in SBS-J than SBS-JC and SBS-JIC, respectively, while MI was more frequent in SBS-JC and SBS-JIC. Within countries: SBS-J represented 75% or more of patients in UK and Denmark and 50-60% in the other countries, except Poland where SBS-JC prevailed. CD was the main underlying disease in UK, USA, Denmark and The Netherlands, while MI prevailed in France, Italy and Poland. CONCLUSIONS: SBS-IF type is primarily determined by the underlying disease, with significant variation between countries. These novel data will be useful for planning and managing both clinical activity and research studies on SBS.

Abstract

Natriuretic peptides (NPs) and their receptors (NPRs) are expressed in the heart, but their effects on myocyte function are poorly understood. Because NPRs are coupled to synthesis of cGMP, an activator of the sarcolemmal [Na.sup.+]-[K.sup.+] pump, we examined whether atrial natriuretic peptide (ANP) regulates the pump. We voltage clamped rabbit ventricular myocytes and identified electrogenic [Na.sup.+]-[K.sup.+] pump current (arising from the 3:2 [Na.sup.+]:[K.sup.+] exchange and normalized for membrane capacitance) as the shift in membrane current induced by 100 [micro]mol/1 ouabain. Ten nanomoles per liter ANP stimulated the [Na.sup.+]-[K.sup.+] pump when the intracellular compartment was perfused with pipette solutions containing 10 mmol/1 [Na.sup.+] but had no effect when the pump was at near maximal activation with 80 mmol/1 [Na.sup.+] in the pipette solution. Stimulation was abolished by inhibition of cGMP-activated protein kinase with KT-5823, nitric oxide (NO)-activated guanylyl cyclase with 1H-[1,2,4]oxadiazole[4,3-a]quinoxalin-1-one (ODQ), or NO synthase with [N.sup.G]-nitro-L-arginine methyl ester (L-NAME). Since synthesis of cGMP by NPR-A and NPR-B is not NO dependent or ODQ sensitive, we exposed myocytes to AP-811, a highly selective ligand for the NPR-C 'clearance' receptor. It abolished ANP-induced pump stimulation. Conversely, the selective NPR-C agonist ANP(423) reproduced stimulation. The stimulation was blocked by L-NAME. To examine NO production in response to ANP(4-23), we loaded myocytes with the NO-sensitive fluorescent dye diacetylated diaminofluorescein-2 and examined them by confocal microscopy. ANP(4-23) induced a significant increase in fluorescence, which was abolished by L-NAME. We conclude that NPs stimulate the [Na.sup.+]-[K.sup.+] pump via an NPR-C and NO-dependent pathway. cyclic guanosine 3',5'-cyclic monophosphate-activated kinase; nitric oxide synthase; congestive cardiac failure; atrial natriuretic peptide

Abstract

Pharmacological delivery of nitric oxide (NO) stimulates the cardiac [Na.sup.+]-[K.sup.+] pump. However, effects of NO synthesized by NO synthase (NOS) often differ from the effects of NO delivered pharmacologically. In addition, NOS can become 'uncoupled' and preferentially synthesize [O.sub.2*.sup.-], which often has opposing effects to NO. We tested the hypothesis that NOS-synthesized NO stimulates [Na.sup.+]-[K.sup.+] pump activity, and uncoupling of NOS inhibits it. To image NO, we loaded isolated rabbit cardiac myocytes with 4,5-diaminofluorescein-2 diacetate (DAF-2 DA) and measured fluorescence with confocal microscopy. L-Arginine (L-Arg; 500 [micro]mol/l) increased DAF-2 DA fluorescence by 51% compared with control (n = 8; P < 0.05). We used the whole cell patch-clamp technique to measure electrogenic [Na.sup.+]-[K.sup.+] pump current (Ip). Mean [I.sub.p] of 0.35 [+ or -] 0.03 pA/pF (n = 44) was increased to 0.48 [+ or -] 0.03 pA/pF (n = 7, P < 0.05) by 10 [micro]mol/l L-Arg in pipette solutions. This increase was abolished by NOS inhibition with radicicol or by NO-activated guanylyl cyclase inhibition with IH-[l,2,4]oxadiazole[4,3-a]quinoxalin-l-one. We next examined the effect of uncoupling NOS using paraquat. Paraquat (1 mmol/l) induced a 51% increase in the fluorescence intensity of [O.sub.2*.-]-sensitive dye dihydroethidium compared with control (n = 9; P < 0.05). To examine the functional effects of uncoupling, we measured [I.sub.p] with 100 [micro]mol/1 paraquat included in patch pipette solutions. This decreased [I.sub.p] to 0.28 [+ or -] 0.03 pA/pF (n = 12; P < 0.001). The paraquat-induced pump inhibition was abolished by superoxide dismutase (in pipette solutions). We conclude that NOS-mediated NO synthesis stimulates the [Na.sup.+]-[K.sup.+] pump, whereas uncoupling of NOS causes [O.sub.2*.-]-mediated pump inhibition. myocyte; nitric oxide; superoxide: oxidative stress

Abstract

Contains fulltext : 220087.pdf (Publisher’s version ) (Closed access), BACKGROUND & AIMS: The safety and effectiveness of a home parenteral nutrition (HPN) program depends both on the expertise and the management approach of the HPN center. We aimed to evaluate both the approaches of different international HPN-centers in their provision of HPN and the types of intravenous supplementation (IVS)-admixtures prescribed to patients with chronic intestinal failure (CIF). METHODS: In March 2015, 65 centers from 22 countries enrolled 3239 patients (benign disease 90.1%, malignant disease 9.9%), recording the patient, CIF and HPN characteristics in a structured database. The HPN-provider was categorized as health care system local pharmacy (LP) or independent home care company (HCC). The IVS-admixture was categorized as fluids and electrolytes alone (FE) or parenteral nutrition, either commercially premixed (PA) or customized to the individual patient (CA), alone or plus extra FE (PAFE or CAFE). Doctors of HPN centers were responsible for the IVS prescriptions. RESULTS: HCC (66%) was the most common HPN provider, with no difference noted between benign-CIF and malignant-CIF. LP was the main modality in 11 countries; HCC prevailed in 4 European countries: Israel, USA, South America and Oceania (p < 0.001). IVS-admixture comprised: FE 10%, PA 17%, PAFE 17%, CA 38%, CAFE 18%. PA and PAFE prevailed in malignant-CIF while CA and CAFE use was greater in benign-CIF (p < 0.001). PA + PAFE prevailed in those countries where LP was the main HPN-provider and CA + CAFE prevailed where the main HPN-provider was HCC (p < 0.001). CONCLUSIONS: This is the first study to demonstrate that HPN provision and the IVS-admixture differ greatly among countries, among HPN centers and between benign-CIF and cancer-CIF. As both HPN provider and IVS-admixture types may play a role in the safety and effectiveness of HPN therapy, criteria to homogenize HPN programs are needed so that patients can have equal access to optimal CIF care.

Abstract

Contains fulltext : 225267.pdf (Publisher’s version ) (Closed access), BACKGROUND AND AIM: No marker to categorise the severity of chronic intestinal failure (CIF) has been developed. A 1-year international survey was carried out to investigate whether the European Society for Clinical Nutrition and Metabolism clinical classification of CIF, based on the type and volume of the intravenous supplementation (IVS), could be an indicator of CIF severity. METHODS: At baseline, participating home parenteral nutrition (HPN) centres enrolled all adults with ongoing CIF due to non-malignant disease; demographic data, body mass index, CIF mechanism, underlying disease, HPN duration and IVS category were recorded for each patient. The type of IVS was classified as fluid and electrolyte alone (FE) or parenteral nutrition admixture (PN). The mean daily IVS volume, calculated on a weekly basis, was categorised as <1, 1-2, 2-3 and >3 L/day. The severity of CIF was determined by patient outcome (still on HPN, weaned from HPN, deceased) and the occurrence of major HPN/CIF-related complications: intestinal failure-associated liver disease (IFALD), catheter-related venous thrombosis and catheter-related bloodstream infection (CRBSI). RESULTS: Fifty-one HPN centres included 2194 patients. The analysis showed that both IVS type and volume were independently associated with the odds of weaning from HPN (significantly higher for PN <1 L/day than for FE and all PN >1 L/day), patients' death (lower for FE, p=0.079), presence of IFALD cholestasis/liver failure and occurrence of CRBSI (significantly higher for PN 2-3 and PN >3 L/day). CONCLUSIONS: The type and volume of IVS required by patients with CIF could be indicators to categorise the severity of CIF in both clinical practice and research protocols.

Abstract

A study was conducted to analyze mechanisms of Na+-K+ pump regulation in cardiac myocytes during hyposmolar swelling. Single ventricular myocytes were determined from New Zealand White rabbits. Experimental results indicated that swelling-induced pump stimulation correlates with the activation of tyrosine kinase, phosphatidylinositol 3-kinase and a serine/threonine protein phosphatase.

Abstract

Contains fulltext : 165702.pdf (publisher's version ) (Closed access), Intestinal failure (IF) is the consequence of a reduction of gut function below the minimum necessary for the absorption of nutrients from the gastrointestinal tract. Types I and II comprise acute intestinal failure (AIF). Although its prevalence is relatively low, type II AIF is serious and requires specialist multidisciplinary care, often for prolonged periods before its resolution. The key aspects are: sepsis control, fluid and electrolyte resuscitation, optimization of nutritional status, wound care, appropriate surgery and active rehabilitation. The ESPEN Acute Intestinal Failure Special Interest Group (AIF SIG) has devised this position paper to provide a state-of-the-art overview of the management of type II AIF and to point out areas for future research.
