Catheter salvage or removal in catheter-related bloodstream infections with Staphylococcus aureus in children with chronic intestinal failure receiving home parenteral nutrition and the use of prophylactic taurolidine catheter lock solution: A descriptive cohort study.

BACKGROUND: Children with chronic IF require long-term home parenteral nutrition (HPN), administered through a central venous catheter. Catheter-related bloodstream infection (CRBSI) with Staphylococcus aureus is known to be a serious infection with a high mortality rate and risk of complications. A standardized protocol on the management of S aureus CRBSIs in children receiving HPN is lacking. The aim of this study is to evaluate the effectiveness and safety of the current management in an HPN expertise center in the Netherlands. METHODS: We performed a retrospective descriptive cohort study between 2013 and 2022 on children 0-18 years of age with chronic IF requiring long-term HPN. Our primary outcomes were the incidence of S aureus CRBSI per 1000 catheter days, catheter salvage attempt rate, and successful catheter salvage rate. Our secondary outcomes included complications and mortality. RESULTS: A total of 74 patients (39 male; 53%) were included, covering 327.8 catheter years. Twenty-eight patients (38%) had a total of 52 S aureus CRBSIs, with an incidence rate of 0.4 per 1000 catheter days. The catheter salvage attempt rate was 44% (23/52). The successful catheter salvage rate was 100%. No relapse occurred, and no removal was needed after catheter salvage. All complications that occurred were already present at admission before the decision to remove the catheter or not. No patients died because of an S aureus CRBSI. CONCLUSION: Catheter salvage in S aureus CRBSIs in children receiving HPN can be attempted after careful consideration by a multidisciplinary team in an HPN expertise center.

A scoping review of parenteral requirements (macronutrients, fluid, electrolytes and micronutrients) in adults with chronic intestinal failure receiving home parenteral nutrition.

INTRODUCTION: Home parenteral nutrition (HPN) prescriptions should be individualised in adults with chronic intestinal failure (IF). The aims of the review were to explore HPN requirements and available guidelines and to determine whether adults (≥ 18 years) receive recommended parenteral nutrient doses. METHODS: Online databases searches identified empirical evidence (excluding case-reports), reviews and guidelines (Published 2006-2024 in English language). Additional reference lists were hand-searched. Older studies, cited in national guidelines were highlighted to map evidence source. Two reviewers screened 1660 articles independently, with 98 full articles assessed and 78 articles included (of which 35 were clinical studies). Citation tracking identified 12 older studies. RESULTS: A lack of evidence was found assessing parenteral macronutrient (amounts and ratios to meet energy needs), fluid and electrolyte requirements. For micronutrients, 20 case series reported serum levels as biomarkers of adequacy (36 individual micronutrient levels reported). Studies reported levels below (27 out of 33) and above (24 out of 26) reference ranges for single micronutrients, with associated factors explored in 11 studies. Guidelines stated recommended parenteral dosages. Twenty-four studies reported variable proportions of participants receiving HPN dosages outside of guideline recommendations. When associated factors were assessed, two studies showed nutrient variation with type of HPN administered (multichamber or individually compounded bags). Five studies considered pathophysiological IF classification, with patients with short bowel more likely to require individualised HPN and more fluid and sodium. CONCLUSIONS: This review highlights substantial evidence gaps in our understanding of the parenteral nutritional requirements of adult receiving HPN. The conclusions drawn were limited by temporal bias, small samples sizes, and poor reporting of confounders and dose. Optimal HPN nutrient dose still need to be determined to aid clinical decision-making and further research should explore characteristics influencing HPN prescribing to refine dosing recommendations.

High Dose Fish Oil Added to Various Lipid Emulsions Normalizes Superoxide Dismutase 1 Activity in Home Parenteral Nutrition Patients.

(1) Objectives: Intestinal failure in home parenteral nutrition patients (HPNPs) results in oxidative stress and liver damage. This study investigated how a high dose of fish oil (FO) added to various lipid emulsions influences antioxidant status and liver function markers in HPNPs. (2) Methods: Twelve HPNPs receiving Smoflipid for at least 3 months were given FO (Omegaven) for a further 4 weeks. Then, the patients were randomized to subsequently receive Lipoplus and ClinOleic for 6 weeks or vice versa plus 4 weeks of Omegaven after each cycle in a crossover design. Twelve age- and sex-matched healthy controls (HCs) were included. (3) Results: Superoxide dismutase (SOD1) activity and oxidized-low-density lipoprotein concentration were higher in all baseline HPN regimens compared to HCs. The Omegaven lowered SOD1 compared to baseline regimens and thus normalized it toward HCs. Lower paraoxonase 1 activity and fibroblast growth factor 19 (FGF19) concentration and, on the converse, higher alkaline phosphatase activity and cholesten concentration were observed in all baseline regimens compared to HCs. A close correlation was observed between FGF19 and SOD1 in baseline regimens. (4) Conclusions: An escalated dose of FO normalized SOD1 activity in HPNPs toward that of HCs. Bile acid metabolism was altered in HPNPs without signs of significant cholestasis and not affected by Omegaven.

Risk factors for catheter-related bloodstream infections in patients with intestinal failure undergoing home parenteral nutrition: a single-center study.

PURPOSE: The incidence and risk factors of catheter-related bloodstream infections (CRBSI) in patients with intestinal failure (IF) have not been established, partly because catheter management methods vary from different facilities. This study aimed to identify the risk factors and incidence rate of CRBSIs in patients with IF who were given prophylactic treatment. METHODS: Sixteen patients with IF who required home parenteral nutrition were enrolled in this study. Prophylactic management of CRBSI included monthly ethanol lock therapy and standardized infection prevention education. The outcomes included the incidence and risk factors of CRBSI. RESULTS: The median incidence rate of CRBSI was 1.2 per 1000 catheter days. Univariate analysis showed that the risk of developing CRBSI was significantly associated with short bowel syndrome (< 30 cm) (p = 0.016). Other relevant findings included a significant negative correlation between serum albumin and CRBSI rate (r = - 0.505, p = 0.046), and past history of mixed bacterial infections was significantly associated with increased CRBSI rate (p = 0.013). CONCLUSION: CRBSIs can still develop despite undergoing prophylactic management. Risk factors for CRBSI include the residual intestinal length, nutritional status, and susceptibility to certain microorganisms.

Implementation of a parenteral nutrition home care programme in a tertiary hospital.

Introduction: Aim: the objective of this study was to describe the results of the implementation of a home parenteral nutrition (HPN) care programme (Nutrihome©) in a cohort of patients treated at a tertiary hospital. Methods: retrospective study of the patients included in Nutrihome© at Hospital General Universitario Gregorio Marañón, Madrid, Spain. Nutrihome consists of different modules including pre-discharge nursing hospital visits and nursing home visits, deliveries of the infusion pump, consumables and parenteral nutrition bags, patient training, weekly scheduled nursing home visits, scheduled nursing phone calls, stock control phone calls and 24-hour on-call line manned by the nurses. Results: the study included 8 (75 % women) and 10 (70 % women) patients in the Nutrihome© pilot and Nutrihome© programme, respectively. A total 37 adverse events were reported during Nutrihome© pilot, 26 of which were technical, 9 clinical, 1 was catheter-related and 1 other event. Nutrihome© programme registered a total of 107 adverse events reported, 57 of which were technical, 21 clinical, 16 were catheter-related and 13 were other events. A total of 99 % of these events were solved by Nutrihome© via phone calls or home visits. Conclusions: Nutrihome© programme has been extremely useful during this pandemic, facilitaing both the start of HPN and training at the patient home without the need for hospitalisation. Additionally, the adverse events reported and solved by Nutrihome© not only reduced the physicians' burden during those tough times and the patients´ stress of being hospitalised during a pandemic, but supported the entire healthcare system.

Introducción: Objetivo: el objetivo de este estudio fue describir los resultados de la implementación de un programa de cuidados de nutrición parenteral domiciliaria (NPD) (Nutrihome©) en una cohorte de pacientes atendidos en un hospital terciario. Métodos: estudio retrospectivo de los pacientes incluidos en Nutrihome© en el Hospital General Universitario Gregorio Marañón de Madrid (España). Nutrihome consta de diferentes módulos que incluyen visitas de enfermería previas al alta y visitas al domicilio, entregas de la bomba de infusión, consumibles y bolsas de nutrición parenteral, formación del paciente, visitas semanales al domicilio programadas, llamadas telefónicas de enfermería programadas, llamadas telefónicas de control de existencias y atención telefónica de enfermería las 24 horas al día. Resultados: el estudio incluyó a 8 (75 % mujeres) y 10 (70 % mujeres) pacientes en el piloto Nutrihome© y en el programa Nutrihome©, respectivamente. Durante el piloto, se registraron un total de 37 eventos adversos, de los cuales 26 fueron técnicos, 9 clínicos, 1 relacionado con el catéter y 1 otro evento. Durante el programa Nutrihome©, se registró un total de 107 eventos adversos, de los cuales 57 fueron técnicos, 21 clínicos, 16 relacionados con el catéter y 13 otros eventos. El 99 % de estos eventos fueron resueltos por Nutrihome© por teléfono o mediante visitas a domicilio. Conclusiones: el programa Nutrihome© ha sido de gran utilidad durante esta pandemia, posibilitando tanto el inicio de la NPD como la formación en el domicilio del paciente sin necesidad de hospitalización. Además, los eventos adversos descritos y resueltos por Nutrihome© no solo redujeron la carga de los médicos durante esos tiempos difíciles y el estrés de los pacientes derivado de estar hospitalizados durante la pandemia, sino que fue un apoyo para todo el sistema de salud.

Home Parenteral Nutrition for Children: What Are the Factors Indicating Dependence and Mortality?

Parenteral nutrition (PN) in children with short bowel syndrome is crucial and lifesaving. Taking care of such patients requires interprofessional practice and multiple team resource management. Home PN (HPN) usage allows patients and families to live regular lives outside hospitals. We share our experiences for the last two decades and identify the risk factors for complications and mortality. A retrospective study of HPN patients was conducted between January 2000 and February 2022. Medical records of age, body weight, diagnosis, length of residual intestines, HPN period, central line attempts, complications, weaning, and survival were collected and analyzed. The patients were classified as HPN free, HPN dependent, and mortality groups. A total of 25 patients received HPN at our outpatient clinic, and one was excluded for the adult age of disease onset. There were 13 patients (54.1%) who were successfully weaned from HPN until the record-enroled date. The overall mortality rate was 20.8% (five patients). All mortality cases had prolonged cholestasis, Child Class B or C, and a positive Pediatric End-Stage Liver Disease (PELD) score. For HPN dependence, extended resection and multiple central line placement were two significant independent factors. Cholestasis, Child Class B or C, and positive PELD score were the most important risk factors for mortality. The central line-related complication rate was not different in all patient groups. The overall central line infection rate was 1.58 per 1000 catheter days. Caution should be addressed to prevent cholestasis and intestinal failure-associated liver disease during the HPN period, to prevent mortality. By understanding the risks of HPN dependence and mortality, preventive procedures could be addressed earlier.

Effect of home parenteral nutrition in malnourished patients.

OBJECTIVE: The goal of our research was to determine the impact of clinical nutrition in the form of home parenteral nutrition (HPN) in patients with nutritional disorders, most often caused by diseases of the digestive tract, with the risk of developing malnutrition. PATIENTS AND METHODS: We retrospectively evaluated 39 patients from the Gastroenterology Clinic and the Home Parenteral Nutrition Center of the University Hospital Bratislava, whose nutritional status was evaluated based on the determination of the body mass index (BMI), the completed nutritional risk screening (NRS) questionnaire and the determination of performance status. Subsequently, after fulfilling the criteria for HPN, the initiation of parenteral nutrition (PN) followed, implemented in a domestic environment for the following two years as HPN. During this period, we did a monthly check-up of the objective condition and laboratory parameters of the enrolled patients, which were the basis for adjusting the nutritional treatment. We also evaluated the occurrence of infectious and thrombotic complications clinically and on the basis of laboratory parameters focused on culture and hemocoagulation examination. After two years, we performed control exit examinations, which we compared with the entrance examinations and statistically evaluated the success of the treatment. We evaluated the obtained data using standard statistical methods. RESULTS: During HPN, there was a statistically significant elevation of the individual monitored values ​​(BMI, absolute lymphocytes count, cholesterol, cholinesterase, total proteins, albumins), which clearly proves correctly indicated and managed HPN. We recorded vein thrombosis in v. subclavia and v. jugularis in 6 (15 %) patients. Subsequent catheter extraction was necessary after unsuccessful catheter insertion. In 13 (33 %) patients, tunneled catheter replacement was required due to infection. The mortality rate in our group was 8 % (3 patients). These were female patients aged 39, 42, and 66 years. The cause of death in all of these patients was the underlying diagnosis (oncohematological disease, systemic connective tissue disease, and repeated resections of the digestive tract for inflammatory GIT disease with the development of severe malnutrition). We recorded a positive effect of applied HPN in all three patients until death.We did not register any factors that would have a relevant influence on the success of administered HPN. CONCLUSION: Based on our results, we can conclude that the patients included in the HPN were correctly indicated, and all of them, based on the monitored parameters (regardless of gender, age, initial diagnosis, or BMI value), benefited from the applied treatment, which was correctly chosen based on their individual needs. Our results clearly document the irreplaceable role of HPN in the management of patients with nutritional intake disorders leading to the development of malnutrition (Tab. 2, Fig. 10, Ref. 44).

Mortality and parenteral nutrition weaning in patients with chronic intestinal failure on home parenteral nutrition: A 30-year retrospective cohort study.

BACKGROUND: Home parenteral nutrition (HPN) is the standard treatment for patients with chronic intestinal failure (CIF). Mortality and weaning rates of these patients differ widely among cohorts; however, these outcomes were often considered independent-rather than competing-events, leading to an upward bias of the retrieved estimates. OBJECTIVES: The aim of this retrospective cohort study was to evaluate, evaluating through a competing risk analysis, the rates and predictors of mortality and weaning in CIF patients from an Italian referral center. METHODS: All adult patients with CIF receiving > 3 mo HPN from 1985 until 2016 were enrolled. Clinical information was collected from the database of the Intestinal Failure Unit of Torino, Italy. Patients were stratified according to the presence or not of short bowel syndrome (SBS). RESULTS: The cumulative incidences of death and weaning were 27.3% and 32.3% and 39.0% and 33.7% at 5 and 10 y from HPN initiation, respectively. At multivariable competing risk analyses, mortality was predicted by age (sub-distribution hazard ratio [SHR] = 1.65 per 10-y increase; 95% CI, 1.35-2.01), type 3 SBS (SHR = 0.38; 0.15-0.94), small bowel length ≥ 100 cm (SHR = 0.42; 0.22-0.83), and reconstructive surgery (SHR = 0.11; 0.02-0.64) in SBS patients, and by age (SHR = 1.38 per 10-y increase; 1.16-1.64) and presence of stoma (SHR = 0.30; 0.12-0.78) in non-SBS patients. In the same model, weaning was predicted by type 3 SBS (SHR = 6.86; 3.10-15.16), small bowel length ≥ 100 cm (SHR = 3.54; 1.99-6.30), and reconstructive surgery (SHR = 2.86; 1.44-5.71) in SBS patients, and by age (SHR = 0.79 per 10-y increase; 0.66-0.94) and presence of stoma (SHR = 2.64; 1.38-5.07) in non-SBS patients. CONCLUSIONS: Surgical procedures strongly affected mortality and weaning risk in CIF patients.

Quality of life and home parenteral nutrition: a survey of UK healthcare professionals' knowledge, practice and opinions.

BACKGROUND: There is increasing interest in the assessment of health-related quality of life (QoL) in the care of patients treated with home parenteral nutrition (HPN). However, it is not known whether healthcare professionals (HCPs) have embedded QoL assessment into routine clinical practice in line with current guidelines to favour a more holistic approach to HPN care. The aim of this study was to assess knowledge, current practice and the opinions of HCPs regarding QoL in care of patients on HPN. METHODS: An online survey was distributed via email to HCPs working with HPN patients throughout England, Scotland, Wales and Northern Ireland. Participants were identified using a mailing list for the British Intestinal Failure Alliance, a specialist group within the British Association for Parenteral and Enteral Nutrition. RESULTS: The survey was completed by 67 professionals comprising 24 dietitians, 17 nurses, 14 gastroenterologists, 6 pharmacists, 5 surgeons and 1 psychologist. Of these, 54 (80%) participants agreed that the measurement of QoL is useful. In contrast, 38 (57%) of all participants, including 27 (50%) of those participants who agreed that the measurement of QoL was useful, never measured QoL. Knowledge of QoL literature was rated as poor or very poor by 27 (40%) participants. CONCLUSIONS: Despite the perceived usefulness and importance of QoL assessment, very few HCPs embed it into clinical practice. Knowledge of QoL literature and QoL tools is variable, and there is significant variability in QoL practice. This is clear in terms of the frequency of QoL assessments and heterogeneity in methodology. In contrast, there was almost unanimous agreement that the complications associated with HPN contribute to poorer QoL. There is a need for specific, evidence-based, clinical practice guidelines detailing how to define and measure QoL in this patient population.

Infusion timing and sleep habits of adults receiving home parenteral and enteral nutrition: A patient-oriented survey study.

BACKGROUND: The emerging field of chrononutrition investigates the effects of the timing of nutritional intake on human physiology and disease pathology. It remains largely unknown when patients receiving home nutrition support routinely administer home parenteral nutrition (HPN) and/or home enteral nutrition (HEN). METHODS: The present descriptive study included data collected from a patient-oriented survey designed to assess the timing of infusions and sleep habits of patients receiving HPN and HEN in the United States. RESULTS: A total of 100 patients were included. Patients had a mean age of 44.1 years and 81% were female. Among 73 patients supported with HPN and 27 patients supported with HEN, 86% and 44% reported overnight infusions, respectively. The median start and end times of overnight infusions were 2100 (interquartile range [IQR] = 1900-2200) and 0800 (IQR = 0700-1000), respectively, for HPN and 2000 (IQR = 1845-2137) and 0845 (IQR = 0723-1000), respectively, for HEN. Overnight infusions started 2.0 h (IQR = 1.1-3.0) and 2.0 h (IQR = 0.6-3.3) before bedtime for HPN and HEN, respectively, and stopped 12.9 min (IQR = -21.3 to 29.1) and 30.0 min (IQR = -17.1 to 79.3) after wake time for HPN and HEN, respectively. Sleep disruption because of nutrition support or urination was most common among patients receiving infusions overnight compared with those receiving infusions continuously or during the daytime. CONCLUSIONS: Our survey study focusing on a novel and medically relevant dimension of nutrition found that most HPN-dependent and HEN-dependent patients receive infusions overnight while asleep. Our findings suggest that overnight infusions coinciding with sleep may result in sleep and circadian disruption.

Taurolidine-related adverse events in patients on home parenteral nutrition frequently indicate catheter-related problems.

BACKGROUND & AIMS: A catheter-related bloodstream infection (CRBSI) is a serious complication of home parenteral nutrition (HPN) treatment. Despite taurolidine's frequent use as catheter lock solution (CLS) to prevent CRBSIs and its presumed favourable safety profile, data on taurolidine-related adverse events (AEs) and the clinical implications thereof remain merely anecdotal. Aim of this study was to explore taurolidine-related AEs in our large cohort of HPN patients and to develop an algorithm on how to deal with these AEs in clinical practice. METHODS: This retrospective cohort study comprised all adult HPN patients who used taurolidine as a CLS between 2006 and 2021 at our national HPN referral centre. Primary outcome was to identify taurolidine-related AEs. Secondary outcomes were median time to a taurolidine-related AEs and development of a clinical algorithm. A taurolidine-related AE was defined as an event that occurred directly after instillation of taurolidine in the CVAD or at start of fluid/PN infusion. RESULTS: In total, 470 patients used taurolidine during 700.232 catheter days. In 89 (19%) patients, 103 mild- to severe AEs related to taurolidine were observed. Six patients developed an allergic reaction. Reported AEs compromised vascular access device-related problems (group A) or taurolidine-related problems (group B) in 53 (51%) and 50 (49%), patients, respectively. In groups A and B, 51 (85%) and 21 (18%) patients presented with taurolidine infusion-related pain. Upon rechallenge, 45 (85%) and 16 (32%) patients, respectively, successfully resumed taurolidine locking without residual symptoms. CONCLUSION: In this study, use of taurolidine as CLS was generally safe. Most reported AEs were vascular access device-related, and the majority of symptoms concerned pain. Upon rechallenge, a substantial number of patients, especially those in whom pain was the main symptom, could resume CLS locking after addressing the underlying catheter-related problem. Based on these results, we present a clinical algorithm for patients with possible taurolidine-related symptoms.

Increase of recurrent central line-associated bloodstream infections in children with home parenteral nutrition in a rehabilitation care facility compared to home.

BACKGROUND AND AIMS: Central line-associated bloodstream infections (CLABSIs) are the main complication in children with home parenteral nutrition (HPN) and some patients develop recurrent CLABSIs (REC-CLABSIs), defined as two or more infections within six months. Our aims were to assess the incidence and to characterize the risk factors of REC-CLABSIs in children with HPN. METHODS: We characterized 79 HPN children from 2014 to 2019 and calculated the incidence of CLABSIs. To minimize the risk of bias related to the exposure time of the septic risk, we paired the patients according to their central venous catheter (CVC) dwell time. After analyzing the whole cohort, a univariate and multivariate unconditional logistic regression was performed on the paired cohort. RESULTS: We included 75 (94.9%) children with a mean age of 7.11 years. The rate of septicemia was 1.55/1000 CVC days, mainly with Staphyloccocus sp. The patients with recurrent CLABSIs (REC group) represented 25% of the cohort, with an incidence of 2.99/1000 CVC days. In the whole cohort, a higher risk of recurrent infections was significantly associated with a longer CVC dwell time (OR = 1.04, IC 95% [1.01-1.06], p = 0.004), and with care located in rehabilitation care facilities (RCF) compared to home (OR = 6, IC 95% [1.5-26.6], p = 0.012). When children were paired according to their CVC dwell time, only in univariate analysis did the care in RCF remain significant (OR = 6.27, IC 95% [1.21-32.5], p = 0.03). CONCLUSIONS: Recurrent CLABSIs incidence was 2.99/1000 CVC days. Our study suggests that preventive measures should be implemented especially in RCFs to reduce the proportion of children with recurrent infections. A multicenter study is needed to confirm our results in a larger cohort with several RCFs.

Sleep patterns of patients receiving home parenteral nutrition: A home-based observational study.

BACKGROUND: Patients supported with home parenteral nutrition (HPN) often report poor sleep; however, limited research has been conducted to objectively measure sleep patterns of HPN-dependent patients. METHODS: We aimed to characterize the sleep patterns of patients receiving HPN through 7-day actigraphy in a home-based observational study. Sleep measures of clinical importance were derived from actigraphy, including sleep duration, sleep efficiency, sleep onset latency, and wake after sleep onset. Participants also completed validated sleep surveys. RESULTS: Twenty participants completed all study procedures (mean [SD]: age = 51.6 [13.9] years, body mass index = 21.4 [4.6], and 80% female). The population median (IQR) for sleep duration, sleep efficiency, sleep onset latency, and wake after sleep onset was 6.9 (1.1) h, 83.3% (7.8%), 11.8 (7.1) min, and 57.2 (39.9) min, respectively, and 55%, 60%, 35%, and 100% of participants did not meet the recommendations for these measures from the National Sleep Foundation. Sixty-five percent of participants reported napping at least once during the 7-day period. Based on the Insomnia Severity Index, 70% of participants were classified as having subthreshold or more severe insomnia. Based on the Pittsburgh Sleep Quality Index, 85% were classified as having significant sleep disturbance. CONCLUSION: Most HPN-dependent patients likely have disrupted sleep largely driven by difficulty maintaining sleep. The extent to which HPN contributed to poor sleep cannot be elucidated from this observational study. Addressing known factors that contribute to sleep disruption and considering sleep interventions may improve the overall quality of life of patients receiving HPN.

Longitudinal evolution of catheter-related bloodstream infections, kidney function and liver status in a nationwide adult intestinal failure cohort.

OBJECTIVES: The development of intestinal failure-related complications in Finnish adults is unknown. This study aimed to investigate the incidence of catheter-related bloodstream infections (CRBSI), and the longitudinal changes in biochemical liver and kidney tests in a nationwide cohort. MATERIALS AND METHODS: The search for Finnish adults with intestinal failure (IF) utilized a survey to Finnish health-care providers (n = 111) with the potential to provide long-term parenteral support (PS) for adult IF. Our nationwide, cross-sectional cohort included all IF patients aged ≥ 18 years who had received PS for ≥ 120 d in 2017. Data regarding CRBSI and biochemical liver and kidney tests were collected from patient records at the start of PS up to the latest available measurement in 2017. RESULTS: In the nationwide cohort of 52 patients, the CRBSI incidence was 1.35/1000 catheter days. Seventy-three percent of CRBSI in a long-term catheter led to catheter replacement. During a median PS duration of 27.5 (interquartile range [IQR] 11.3-57.3) months, a statistically significant median change occurred in estimated glomerular filtration rate (eGFR; -8.5 ml/min/1.73 m2, IQR -30-7, p = .005) and alkaline phosphatase (ALP; 26 U/l, IQR -11-95, p = .019). In a multiple regression model for eGFR at data collection, baseline eGFR and age were strong explanatory variables. CONCLUSIONS: Incidence of CRBSI, but not treatment strategies, in this nationwide adult IF population correspond well to those reported from specialized centers. Decreased kidney function and abnormal liver test results are frequent findings, and even more so over time, emphasizing the importance of regular monitoring.

How Broad Should Gram-Negative Coverage Be for Febrile Parenteral Nutrition Dependent Short Bowel Syndrome Patients?

ABSTRACT: Broader spectrum Gram-negative antibiotics are commonly utilized empirically for central line-associated bloodstream infections (CLABSI) in febrile short bowel syndrome (SBS) patients receiving home parenteral nutrition compared to those used empirically for inpatient-acquired CLABSI. This analysis reports 57 CLABSI in 22 patients with SBS admitted from the community and 78 inpatient-acquired CLABSI in 76 patients over a 5-year period. Proportional Gram-negative CLABSI was similar between the SBS and inpatient-acquired cohorts (43.8% vs42.3%, respectively, P  = 0.78). 1.8% and 10.3% (P = 0.125) of Gram-negative CLABSI were non-susceptible to ceftriaxone and 0% and 3.8% (P = 0.52) were non-susceptible to ceftazidime in the SBS and inpatient-acquired cohorts, respectively. In the SBS cohort, home ethanol lock therapy and prior culture results impacted Gramnegative pathogen distribution. Broader empiric Gram-negative coverage for CLABSI among SBS patients compared to inpatients is unnecessary. Third-generation cephalosporins represent appropriate empiric Gramnegative agents for febrile SBS patients presenting from the community to our institution.

Erythrocyte fatty acid membrane composition in children on long-term parenteral nutrition enriched with ω-3 fatty acids.

BACKGROUND: Composite lipid emulsions containing soybean oil (30%), medium-chain triglycerides (30%), olive oil (25%), and fish oil (15%) (SMOF) are now widely used. OBJECTIVES: We aimed to evaluate the tolerance, the efficiency, and the erythrocyte fatty acid (FA) profile for children on long-term home parenteral nutrition (HPN) receiving a composite fish oil-based emulsion (FOLE). METHODS: At baseline, children (n = 46) with severe intestinal failure highly dependent on parenteral nutrition (PN) for ≥1 y were included in the study when they had received the composite FOLE for >6 mo. Out of this baseline group, only 25 children remained highly PN-dependent (SMOF1, n = 25) and could be assessed a second time, 2.4 y later (SMOF2, n = 25). An independent control group ("weaned off PN" group; n = 24) included children who had been weaned off PN for >2 y (median: 4 y). RBC-FA composition was established by GC-MS. Growth parameters, plasma citrulline, conjugated bilirubin, FA profiles, and the Holman ratio (20:3ω-9/20:4ω-6) were compared between groups. RESULTS: No difference for growth parameters, citrulline, and bilirubin was observed between the SMOF groups after 2.4 y (0.2 < P < 0.8). The weaned-off group did not differ from the SMOF groups for growth parameters (0.2 < P < 0.4) but citrulline was higher (P < 0.0001) and conjugated bilirubin lower (P < 0.01). The composite FOLE induced higher proportions of EPA (20:5n-3) (8.4% ± 2.9%) and DHA (22:6n-3) (11.7% ± 2.2%) than what was observed in weaned-off children (0.8% ± 0.4% and 6.6% ± 2.3%, respectively) but lower proportions of arachidonic acid (20:4n-6). However, the Holman ratio did not vary between groups (P = 0.9), whereas the PUFA concentrations varied widely. CONCLUSIONS: Long-term use of the composite FOLE was well tolerated in HPN-dependent children. The RBC-FA profile alterations were consistent with the ω-3 PUFA-enriched composition of this emulsion without evidence of essential FA deficiency.

Home parenteral nutrition patients on mixed oil lipid emulsion have a higher rate of hospitalizations compare to those on soybean oil- a prospective 2-year cohort study.

BACKGROUND & AIMS: Mixed oil intravenous lipid emulsion (MO ILE) that contains 30% soybean oil (SO), 30% medium chain triglycerides, 25% olive oil and 15% fish oil can benefit hospitalized patients receiving parenteral nutrition (PN) but there are very few studies on its long-term use. Our goal was to evaluate the clinical outcomes of adults receiving home PN (HPN) with MO versus those receiving SO ILE over a 2-year period. METHOD: This is a retrospective analysis of data collected prospectively from a cohort of patients recorded in the Canadian HPN Registry over a 2-year period. HPN patients from academic programs across Canada were entered in the Registry according to a validated protocol. For this study, demographic, nutritional, laboratory and clinical data were extracted from January 1st 2015, when MO lipid emulsion became available in Canada, to July 24th 2019. Clinical data for each patient included: number of hospitalizations, number of hospitalizations related to HPN and number of hospitalization days related to HPN, over a year; incidence of line sepsis per 1000 catheter days and mortality. Data are presented as median (1st, 3rd quartile) for continuous variables and frequency (percentage) for categorical variables. Comparisons between groups were performed using two sample t-test or Wilcoxon Rank Sum tests for continuous variables and Chi-square tests or Fisher's exact tests for categorical variables. Univariate and multiple linear regressions were also carried out. Statistical significance is set at a p-value <0.05. RESULTS: A total of 120 patients were included (MO n = 68, SO n = 52). Significant differences at baseline between the two groups were a higher use of Hickman line (62.12% vs 42%, p = 0.038) and more western Canada based hospital care with MO (75% vs 42.31%, p = 0.0002). The MO group had significantly more hospitalizations (p = 0.001), more hospitalizations related to HPN (p = 0.012) and more hospitalization days related to HPN (p = 0.016) per patient per year compared to SO patients. There was no significant difference between groups for line sepsis per 1000 catheter days (MO: 0.05 (0.0, 1.0) vs SO: 0.0 (0.0, 0.22), p = 0.053) or mortality. All other variables, including biochemical variables, were similar between groups. In a multiple regression analysis, the following factors were significantly associated with a greater number of hospitalizations per patient per year: use of MO, high blood glucose from the last recorded value and having died by the end of the study period. CONCLUSION: This 2-year prospective cohort study suggests an increased risk of hospitalization in HPN patients receiving MO lipid emulsion. The long-term effect of using MO lipid emulsion in HPN patients should be further evaluated using a large randomized controlled trial. THE STUDY WAS REGISTERED IN CLINICALTRIALS.GOV: (NCT02299466).

From hospital unit to intestinal failure center: Twenty years of history.

AIM: Home parenteral nutrition (HPN) is one of the most demanding medical therapies as it is the only option for patients for intestinal failure (IF). No unequivocal policy on how to start and progress with HPN has ever been presented. The IF Center at the Stanley Dudrick's Memorial Hospital in Skawina is one of the biggest centers in Poland, celebrating its twentieth birthday last year. It offered the unique chance to present how to create and grow the IF center, increasing the quality of care. The above became the aim of this study. METHODS: A retrospective analysis of all medical records of HPN patients from the University Hospital and Stanley Dudrick's Memorial Hospital in Skawina. Patient profile, clinical course and treatment outcomes were assessed. The evolution of all aspects of HPN is presented. A brief historical perspective has been added to better illustrate the center's growth and transformation. RESULTS: 608 patients (363 female, 245 male, mean age 55.55 year) from all over Poland were treated between December 1999 and December 2019. The most frequent indication for HPN was mechanical obstruction (277, 45.7%), followed by short bowel syndrome (SBS, 208, 34.3%) and intestinal fistula (46, 7.59%). The most common primary disease was cancer (n = 267), followed by mesenteric ischemia (n = 104), and surgical complications (n = 62). 314 patients (51.8%) died. 73 (12.04%) were successfully weaned off PN. The catheter infection rate reached 0.39/1000 catheter days. CONCLUSIONS: the founding of the HPN center and its further development is possible provided that there is team of dedicated people, supported by hospital base. The real growth opportunity is guaranteed by the reimbursement. It is necessary to adapt to the changing circumstances.

Home Artificial Nutrition in Polish Children: An Analysis of 9-Year National Healthcare Provider Data.

BACKGROUND: Home artificial nutrition (HAN) is a developing method of treatment that reduces the need for hospitalizations. The epidemiology of pediatric HAN in Poland has not yet been covered in detail. This study is a longitudinal nationwide analysis of incidence, prevalence, and patients' profile for HAN in Polish children. METHODS: Assessment of National Health Fund (NFZ) data covering all pediatric patients treated with HAN in Poland between 2010 and 2018. RESULTS: HAN was received by 4426 children, 65 patients were on home enteral nutrition (HEN) or home parenteral nutrition (HPN) at different times (HEN n = 3865, HPN n = 626). HAN was most frequently started before the child was 3 years old and long-term HAN programs (5-9 years) were reported. The most common principal diagnosis in HEN was food-related symptoms and signs. In HPN, it was postoperative gastrointestinal disorders. A regionally differentiated prevalence of HAN patients and centers was demonstrated. Mortality among patients was 24.9% for HEN, and 9.6% for HPN, and the main in-hospital cause of death was cardiac arrest. CONCLUSIONS: HAN's use is increasing and evolving in Poland. Uneven distribution of patients and centers results in difficult access to the nutritional procedure which, together with the increasing number of patients, highlights the need for data analysis and development of nutrition centers.

Quality of life in patients and in family members of those receiving home parenteral support with intestinal failure: A systematic review.

BACKGROUND & AIMS: People with type 3 intestinal failure require regular home parenteral support (HPS) for survival. Intestinal failure is a long term condition and HPS is a burdensome treatment so understanding quality of life (QoL) and how people live with HPS over time is essential. The aim of this review was to assess the impact of HPS on QoL in adults receiving HPS and their family members. METHODS: A systematic review (PROSPERO 2020 CRD42020166197) of the literature was performed using MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trails, PsycInfo, Web of Science and PROSPERO. Included articles were hand searched to identify any other relevant studies. Eligibility assessment was performed independently by two reviewers in an unblinded standardised manner. Quality was assessed using appropriate Joanna Briggs Institute critical appraisal tools. Data were extracted independently by two reviewers using predefined data fields. Certainty of evidence was assessed using GradePro. RESULTS: Included in this review were 12 studies with 1236 patients receiving HPS. There were 10 observational studies and 2 randomised controlled trials. Only studies examining QoL in adults receiving HPS were found. There were no studies examining QoL in family carers of these patients. The quality of evidence was graded as low to high and the certainty of evidence for QoL was graded as very low to low. It was not possible to perform a meta-analysis so a narrative review was conducted. All of the studies considered quality of life using validated questionnaires. QoL of patients receiving HPS was lower than the general population regarding physical functioning. Patients had a higher QoL the fewer nights each week they received HPS. CONCLUSIONS: HPS prescriptions seemed to influence QoL. However, the certainty of evidence was very low to low so there is very little to limited confidence about the effect of HPS on patient QoL. Research into family members' QoL is lacking and requires further investigation.
