RESUMEN
BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of thrombosis. They often need parenteral nutrition (PN) requiring intravenous access for prolonged periods. We assessed the risk of deep vein thrombosis (DVT) associated with peripherally inserted central catheters (PICCs) and tunneled catheters for patients with IBD receiving home PN (HPN). METHODS: Using the Cleveland Clinic HPN Registry, we retrospectively studied a cohort of adults with IBD who received HPN between June 30, 2019 and January 1, 2023. We collected demographics, catheter type, and catheter-associated DVT (CADVT) data. We performed descriptive statistics and Poisson tests to compare CADVT rates among parameters of interest. We generated Kaplan-Meier graphs to illustrate longevity of CADVT-free survival and a Cox proportional hazard model to calculate the hazard ratio associated with CADVT. RESULTS: We collected data on 407 patients, of which, 276 (68%) received tunneled catheters and 131 (32%) received PICCs as their initial catheter. There were 17 CADVTs with an overall rate of 0.08 per 1000 catheter days, whereas individual rates of DVT for PICCs and tunneled catheters were 0.16 and 0.05 per 1000 catheter days, respectively (P = 0.03). After adjusting for age, sex, and comorbidity, CADVT risk was significantly higher for PICCs compared with tunneled catheters, with an adjusted hazard ratio of 2.962 (95% CI=1.140-7.698; P = 0.025) and adjusted incidence rate ratio of 3.66 (95% CI=2.637-4.696; P = 0.013). CONCLUSION: Our study shows that CADVT risk is nearly three times higher with PICCs compared with tunneled catheters. We recommend tunneled catheter placement for patients with IBD who require HPN infusion greater than 30 days.

BACKGROUND: Patients with chronic intestinal failure (CIF) are at increased risk of developing renal impairment. The aim of this study was to evaluate the occurrence of chronic kidney disease (CKD) in patients dependent on home parenteral nutrition (HPN) and assess risk factors for renal impairment, including patients with all mechanisms of CIF. METHODS: This was a cohort study of patients initiated on HPN between March 1, 2015, and March 1, 2020, at a national UK IF Reference Centre. Patients were followed from their first discharge with HPN until HPN cessation or the end of follow-up on December 31, 2021. RESULTS: There were 357 patients included in the analysis. Median follow-up time was 4.7 years. At baseline, >40% of patients had renal impairment, with 15.4% fulfilling the criteria for CKD. Mean estimated glomerular filtration rate (eGFR) decreased significantly during the first year after initiation of HPN from 93.32 ml/min/1.73 m2 to 86.30 ml/min/1.73 m2 at the first year of follow-up (P = 0.002), with sequential stabilization of renal function. Increased age at HPN initiation and renal impairment at baseline were associated with decreased eGFR. By the end of follow-up, 6.7% patients developed renal calculi and 26.1% fulfilled the criteria for CKD. CONCLUSION: This is the largest study of renal function in patients receiving long-term HPN. After the first year following HPN initiation, the rate of decline in eGFR was similar to that expected in the general population. These findings should reassure patients and clinicians that close monitoring of renal function can lead to good outcomes.

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.

INTRODUCTION: Chronic intestinal failure patients (CIF) require a central venous access device (CVAD) to administer parenteral nutrition. Most serious complication related to a CVAD is a central line-associated bloodstream infection (CLABSI). The golden standard to diagnose a CLABSI are blood cultures, however, they may require 1-5 days before getting a result. Droplet digital polymerase chain reaction (ddPCR) for the detection of pathogen 16S/28S rRNA is a novel culture-independent molecular technique that has been developed to enhance and expedite infection diagnostics within two and a half hours. In this study, we prospectively compared ddPCR with blood cultures to detect pathogens in whole blood. METHODS: We included adult CIF patients with a clinical suspicion of CLABSI in this prospective single-blinded clinical study. Blood cultures were routinely collected and subsequently two central samples from the CVAD and two peripheral samples from a peripheral venous access point. Primary outcome was the sensitivity and specificity of ddPCR. RESULTS: In total, 75 patients with 126 suspected CLABSI episodes were included, with 80 blood samples from the CVAD and 114 from peripheral veins. The central ddPCR samples showed a sensitivity of 91% (95%CI 77-98), and specificity of 96% (95%CI 85-99). Peripheral ddPCR samples had a sensitivity of 63% (95%CI 46-77) and specificity of 99% (95%CI 93-100). CONCLUSION: ddPCR showed a high sensitivity and specificity relative to blood cultures and enables rapid pathogen detection and characterization. Clinical studies should explore if integrated ddPCR and blood culture outcomes enables a more rapid pathogen guided CLABSI treatment and enhancing patient outcomes.

BACKGROUND AND AIMS: Short bowel syndrome is a malabsorption disorder typically caused by the physical loss of a portion of the intestine, whereafter the body is unable to adequately absorb nutrients, fluids, and electrolytes. Many patients with short bowel syndrome are reliant on home parenteral nutrition through a tunneled or peripherally inserted central catheter to ensure sufficient hydration and nutrition. Central venous catheters are a nidus for bacteria, and patients are at risk for infections associated with high levels of morbidity and mortality. Lactobacillus is a ubiquitous microorganism that most frequently colonizes mucosal surfaces such as the gastrointestinal tract. Lactobacillus bacteremia is rare, with limited occurrence in current medical literature. METHODS: Our patient is a 60-year-old female with a past medical history significant for multiple abdominal surgeries resulting in short bowel syndrome, with subsequent dependence on home parenteral nutrition via peripherally inserted central catheter. She had type III chronic intestinal failure, category D2, and stage 1 moderate malnutrition. She was originally admitted to the hospital for a presumed pulmonary embolism and was found to have a deep vein thrombosis in the setting of her peripherally inserted central catheter. On admission her abdominal exam was unremarkable, she denied abdominal pain, and her only gastrointestinal complaint was chronic stable diarrhea. During the hospitalization she developed severe left lower quadrant abdominal pain and noted decreased frequency of her bowel movements. A computed tomography scan of her abdomen revealed chronic stable intestinal distension and was concerning for obstruction. Clinically she remained without symptoms of acute obstruction or ileus. During the admission she became febrile, with blood cultures from her peripherally inserted central catheter and peripheral IV growing out gram negative rods determined to be lactobacillus bacteremia. The infectious disease team recommended removal of her peripherally inserted central catheter given their concern for a line infection. RESULTS: The patient was treated with broad-spectrum antibiotics, did well clinically, and was ultimately discharged following reinsertion of her peripherally inserted central catheter after negative repeat blood cultures. Though she initially did well in the outpatient setting, she ultimately passed away ten months later after re-presenting to the hospital in septic shock, secondary to bowel ischemia and suspected fungemia of her peripherally inserted central catheter. CONCLUSIONS: In this case report, we describe an unusual case of a patient with short bowel syndrome on chronic parenteral nutrition who developed catheter-associated lactobacillus bacteremia - the first reported case in an adult patient on parenteral nutrition.

Home parenteral nutrition (HPN) is increasingly prescribed for patients with advanced cancer. This therapy improves free-fat mass, quality of life and survival, but it is not free from complications, especially catheter-related bloodstream infections (CRBSIs). The use of commercial multichamber bags in HPN has not been extensively explored in oncologic patients and their association with complications is not well known. In this prospective cohort study, we included 130 patients with advanced cancer and HPN. We compared the effects of individual compounded bags (n = 87) vs. commercial multichamber bags (n = 43) on complications. There were no differences in any complication, including thrombosis (p > 0.05). There were 0.28 episodes of CRBSI per 1000 catheter days in the individual compounded bag group and 0.21 in the multichamber bag group (p > 0.05). A total of 34 patients were weaned off HPN, 22 with individual bags and 12 with multichamber bags (p = 0.749). Regarding survival when on HPN, the group with individual bags showed a median of 98 days (95% CI of 49-147), whereas those with multichamber bags showed a median of 88 days (95% CI of 43-133 (p = 0.913)). In conclusion, commercial multichamber bags for HPN in patients with advanced cancer are non-inferior when compared to individual compounded bags in terms of complications.

OBJECTIVE: This study is an assessment of home parenteral nutrition service performance and safety and efficacy outcomes in patients with benign chronic intestinal failure. METHODS: This is a retrospective, non-interventional, and multicenter study. Data were collected by trained nurses and recorded in a dedicated registry (SERECARE). RESULTS: From January 1, 2013 to June 30, 2018, data from a total of 683 patients with benign chronic intestinal failure were entered in the registry. Patients included 208 pediatric (53.8% male; median age = 4.0 y) and 475 adult (47.6% male; median age = 59.0 y) participants. On average, patients were visited 5.4 ± 4.5 times and received 1.4 ± 0.8 training sessions. Retraining was not common and mostly due to change of therapy or change of caregiver. Of 939 complications, 40.9% were related to the central venous catheter and were mostly infectious (n = 182) and mechanical (n = 187). The rate of infectious and mechanical complications per 1000 catheter days decreased over 5 y (0.30-0.15 and 0.33 -0.19, respectively). The rate of complications per 1000 catheter days and the mean complications per patient were higher in pediatric than in adult patients. The hospitalization rate was 1.01 per patient throughout the study period. These data were similar to those registered in a previous study period (2002-2011) (n = 1.53 per patient). Changes over time in the efficacy variables were mostly small and non-significant. CONCLUSIONS: This study confirms the importance of setting up and maintaining structured registries to monitor and improve home parenteral nutrition care. Safety outcomes have improved over the years, most likely due to the underlying efficient nursing service.

BACKGROUND: Central venous catheter (CVC) complications are frequently reported in patients receiving home parenteral support (HPS). Compromised CVC integrity or breakage is one such issue. Repairing such breakages can potentially avoid costly and risky catheter replacements. METHODS: We completed a retrospective descriptive cohort study using a prospectively maintained data set, in a national UK intestinal failure reference center. Repair success, CVC longevity, and catheter-related bloodstream infection (CRBSI) rates after repair were the primary outcome measures. RESULTS: A total of 763 patients received HPS. There were 137 CVC repairs: 115 (84%) tunneled CVCs and 22 peripherally inserted central catheters (PICCs) attempted in 72 patients. Of the 137 attempts at CVC repair, 120 (88%) were deemed to be successful, allowing a median duration of subsequent CVC use of 336 days following repair (range 3-1696 days), which equates to 99,602 catheter days of HPS infusion. Three patients had a CRBSI within 90 days of repair, and patients required admission to the hospital for refeeding on 14 occasions following repair, such that hospitalization was avoided in 103/120 (86%) occasions following successful CVC repair. There was no increase in the recorded rate of CRBSIs in patients undergoing CVC repair compared with the CRBSI rates of all HPS-dependent patients under our care during the study period (0.03 vs 0.344/1000 catheter days, respectively). CONCLUSION: This is the largest single-center experience to demonstrate that CVCs, including PICCs, used for the administration of HPS can be safely repaired, prolonging CVC longevity without leading to an increased risk of CRBSI.

INTRODUCTION: Up to 83% of oncology patients are affected by cancer-related malnutrition, depending on tumour location and patient age. Parenteral nutrition can be used to manage malnutrition, but there is no clear consensus as to the optimal protein dosage. The objective of this systematic literature review (SLR) was to identify studies on malnourished oncology patients receiving home parenteral nutrition (HPN) where protein or amino acid delivery was reported in g/kg bodyweight/day, and to compare outcomes between patients receiving low (< 1 g/kg bodyweight/day), standard (1-1.5 g/kg/day), and high-protein doses (> 1.5 g/kg/day). METHODS: Literature searches were performed on 5th October 2021 in Embase, MEDLINE, and five Cochrane Library and Centre for Reviews and Dissemination databases. Searches were complemented by hand-searching of conference proceedings, a clinical trial registry, and bibliographic reference lists of included studies and relevant SLRs/meta-analyses. RESULTS: Nineteen publications were included; sixteen investigated standard protein, two reported low protein, and one included both, but none assessed high-protein doses. Only one randomised controlled trial (RCT) was identified; all other studies were observational studies. The only study to compare two protein doses reported significantly greater weight gain in patients receiving 1.15 g/kg/day than those receiving 0.77 g/kg/day. CONCLUSION: At present, there is insufficient evidence to determine the optimal protein dosage for malnourished oncology patients receiving HPN. Data from non-HPN studies and critically ill patients indicate that high-protein interventions are associated with increased overall survival and quality of life; further studies are needed to establish whether the same applies in malnourished oncology patients.

INTRODUCCIÓN: La Nutrición Parenteral Domiciliaria (NPD) ha demostrado ofrecer importantes be neficios para los pacientes y el sistema de salud. En Chile se desconoce el número de pacientes que se encuentran recibiendo esta modalidad de tratamiento o que podrían ser candidatos a ella. OBJETIVO: Determinar la prevalencia y características clínicas de pacientes con Insuficiencia Intestinal (II) que reciben actualmente NPD o que son candidatos a esta. PACIENTES Y MÉTODO: Estudio descriptivo transversal que incluyó pacientes de 0 a 18 años, con diagnóstico de II que se encontraban recibiendo NP por un tiempo superior a 3 meses en el domicilio, o en el hospital con situación clínica estable y con catéter venoso de larga duración (CVC). A través de una encuesta digitalizada se recolectaron y estudiaron las variables: sexo, antecedentes de nacimiento, indicación para iniciar soporte nutricional parenteral, edad de inicio de NP, tipo de CVC utilizado, frecuencia de NP, estado nutricional, alimentación al último control y complicaciones asociadas al uso de NP. Se utilizó el Programa SPSS Statistics, Versión 21, Macintosh, para el análisis de los datos. El análisis descriptivo consideró análisis de frecuencia y medidas de tendencia central. La prueba de Chi cuadrado y de Fisher se usaron para la comparación de proporciones. RESULTADOS: Se registraron datos de 46 pacientes, cuya edad promedio fue de 55,5 meses. La principal indicación para iniciar la Nutrición Parenteral (NP) fue la disminución de la superficie intestinal (78,3%.). El 63% de los pacientes se encontraba hospitalizado. No se encontraron diferencias significativas entre el lugar de tratamiento y las variables estado nutricional e infecciones de catéter en el último año. CONCLUSIONES: Se identificó la prevalencia de pacientes con NP prolongada y sus características clínicas. No se encontraron diferencias que respalden la entrega de este tratamiento en el hospital por sobre el domicilio. Es necesario desarrollar políticas públicas que garanticen la opción de recibir este tratamiento en el domicilio.
INTRODUCTION: Home parenteral nutrition (HPN) has been shown to offer important benefits for pa tients and the health system. In Chile, the number of patients who are receiving this type of treatment or who could be candidates for it is unknown. OBJECTIVE: To determine the prevalence and clinical characteristics of patients with intestinal insufficiency (II) currently receiving HPN or who are can didates for it. PATIENTS Y METHOD: Cross-sectional descriptive study which included patients aged between 0 to 18 years with diagnosis of II who were receiving parenteral nutrition (PN) for over three months, either at home or in the hospital, with a stable clinical situation and a long-term venous catheter (CVC). Through a digitalized survey, the following variables were collected and studied: gender, birth history, indication to initiate parenteral nutritional support, age of initiation of PN, type of CVC, frequency of PN, nutritional status and feeding in the last control and complications as sociated with the use of PN. Data analysis was performed using the SPSS Statistics Software, Version 21, Macintosh. The descriptive analysis considered frequency analysis and central trend measures. The Chi-square and Fisher tests were used for comparison of proportions. RESULTS: Data from 46 patients were recorded. The average age was 55.5 months. The main indication for initiating the PN was the decrease of the intestinal surface (78.3%). 63% of the patients were hospitalized. No significant differences were found between the place of treatment and the nutritional status and catheter infections variables in the last year. CONCLUSIONS: The prevalence of patients with long-term PN and their clinical characteristics were identified. No differences were found to support the administration of this treatment in the hospital over the home. Public policies must be developed to guarantee the option of receiving this treatment at home.
