Parenteral therapy and complications in patients with intestinal failure in a regional unit

Intestinal failure among adults and children: Similarities and differences

Intestinal failure (IF) is a complex medical condition that is caused by a constellation of disorders, resulting in the gut's inability to adequately absorb fluids and nutrients to sustain hydration, growth, and survival, thereby requiring the use of parenteral fluid and/or nutrition. Significant advancements in intestinal rehabilitation have resulted in improved survival rates for individuals with IF. There are distinct differences, however, related to etiology, adaptive potential and complications, and medical and surgical management when comparing children with adults. The purpose of this review is to contrast the similarities and differences between these two distinct groups and provide insight for future directions, as a growing population of pediatric patients will cross into the adult world for IF management.

ESPEN guideline on Clinical Nutrition in inflammatory bowel disease

The present guideline is an update and extension of the ESPEN scientific guideline on Clinical Nutrition in Inflammatory Bowel Disease published first in 2017. The guideline has been rearranged according to the ESPEN practical guideline on Clinical Nutrition in Inflammatory Bowel Disease published in 2020. All recommendations have been checked and, if needed, revised based on new literature, before they underwent the ESPEN consensus procedure. Moreover, a new chapter on microbiota modulation as a new option in IBD treatment has been added. The number of recommendations has been increased to 71 recommendations in the guideline update. The guideline is aimed at professionals working in clinical practice, either in hospitals or in outpatient medicine, and treating patients with IBD. General aspects of care in patients with IBD, and specific aspects during active disease and in remission are addressed. All recommendations are equipped with evidence grades, consensus rates, short commentaries and links to cited literature.

Anticoagulants decrease the risk for catheter-related venous thrombosis in patients with chronic intestinal failure: A long-term cohort study

BACKGROUND

Catheter-related venous thrombosis (CRVT) is a severe complication of home parental nutrition (HPN). Although primary prevention of CRVT is crucial, there is no consensus on anticoagulant use to prevent this adversity. Aim of this study was to compare CRVT risk in chronic intestinal failure (CIF) patients in the presence or absence of anticoagulants, and to identify CRVT risk factors .

METHODS

This retrospective cohort study comprised adult CIF patients with a central venous access device (CVAD) between 2010 and 2020 who were treated at our national CIF referral center. Analyses were performed at CVAD level. Primary outcome was the CRVT risk of CIF patients using anticoagulants compared to those without anticoagulants.

RESULTS

Overall, 1188 CVADs in 389 patients were included (540.800 CVAD days). Anticoagulants were used in 403 CVADs. In total, 137 CRVTs occurred in 98 patients, resulting in 0.25 CRVTs/1000 CVAD days (95%CI 0.22-0.29). Anticoagulant use was associated with a decreased CRVT risk (OR 0.53 95%CI 0.31-0.89; P = 0.02). Left-sided CVAD insertion (OR 2.00 95%CI 1.36-2.94), a history of venous thrombosis (OR 1.73 95%CI 1.05-2.84), and a shorter period post-insertion (OR 0.78 95%CI 0.65-0.92) were independently associated with an increased CRVT risk.

CONCLUSION

Anticoagulants decreased the CRVT risk. In addition, we identified left-sided vein insertion, a history of venous thrombosis, and a shorter period post CVAD insertion as CRVT risk factors. Further prospective studies should provide guidance whether prophylactic anticoagulant use, especially in higher-risk patients with a left-sided CVAD or a history of venous thrombosis, is justified.

Comparing success rates in central venous catheter salvage for catheter-related bloodstream infections in adult patients on home parenteral nutrition: a systematic review and meta-analysis

BACKGROUND

Catheter-related bloodstream infection (CRBSI) is a life-threatening complication of parenteral nutrition. Therefore, optimal management, ideally with catheter salvage, is required to maintain long-term venous access.

OBJECTIVES

We aimed to evaluate successful catheter salvage rates in patients on home parenteral nutrition (HPN).

METHODS

Studies were retrieved from medical databases, conference proceedings, and article reference lists. Data were collected relating to clinical outcomes of 3 treatments: systemic antibiotics, antimicrobial lock therapy (ALT), and catheter exchange. ORs and 95% CIs were calculated from a mixed logistic effects model.

RESULTS

From 10,036 identified publications, 28 met the inclusion criteria (22 cohort studies, 5 case-control studies, and 1 randomized clinical trial), resulting in a total of 4911 CRBSIs. To achieve successful catheter salvage, the addition of an antimicrobial lock solution was superior to systemic antibiotics alone (OR: 1.75; 95% CI: 1.21, 2.53; P = 0.003). Recurrence of infection was less common in studies that used ALT than in those that used systemic antibiotics alone (OR: 0.26; 95% CI: 0.11, 0.61; P = 0.002). The catheter exchange group was excluded from multilevel regression analysis because only 1 included study applied this treatment. Successful salvage rates were highest for coagulase-negative staphylococci, followed by Gram-negative rods and Staphylococcus aureus .

CONCLUSIONS

The addition of an antimicrobial lock solution seems beneficial for successful catheter salvage in HPN-dependent patients with a CRBSI. Future prospective randomized studies should identify the most effective and pathogen-specific strategy.This review was registered at www.crd.york.ac.uk/PROSPERO as CRD42018102959.

Epidemiology of Infectious and Noninfectious Catheter Complications in Patients Receiving Home Parenteral Nutrition: A Systematic Review and Meta-Analysis

Patients receiving parenteral nutrition (PN) as their primary source of nutrition are at high risk for both infectious and noninfectious catheter complications (catheter-related infections, catheter occlusion, and venous thrombosis). The aim of this review was to synthesize and evaluate what is known about catheter complications and prevention strategies in the PN population. Three electronic databases (Medline, Embase, and CINAHL) were screened for studies published between January 2012 and February 2019 regarding infectious and noninfectious catheter complications in patients receiving PN. Rates of infectious and noninfectious catheter complications, prevalence of causative pathogens, potential risk factors, and prevention strategies via the use of antimicrobial lock therapy (ALT) were assessed. Fifty-three catheter complication studies and 12 ALT studies were included. Studies were grouped by definition of complication: catheter-related bloodstream infections (CRBSI) or central line-associated bloodstream infections (CLABSI). Random effects summary rates per 1000 catheter days were 0.85 CRBSI episodes (95% CI 0.27-2.64) and 1.65 CLABSI episodes (95% CI 1.09-2.48). Use of taurolidine or ethanol ALT was efficacious in reducing infectious catheter complications; however, several studies had concerns for adverse mechanical complications. Potential risk factors for catheter complications were highly varied and often contradictory between studies. The rates of catheter complications were higher among catheterized patients receiving PN compared with nationally reported rates of complications in all catheterized patients. Risk factors for catheter complications need to be better understood for targeted prophylactic use of ALT. Future studies are warranted; however, they should be conducted using more standardized definitions and criteria.
