Management of Home Parenteral Nutrition: Complications and Survival.

BACKGROUND AND AIMS: Parenteral nutrition (PN) has become an efficient, safe, and convenient treatment over years for patients suffering from intestinal failure. Home PN (HPN) enables the patients to have a high quality of life in their own environment. The therapy management however implies many restrictions and potentially severe lethal complications. Prevention and therapy of the latter are therefore of utmost importance. This study aims to assess and characterize the situation of patients with HPN focusing on prevalence of catheter-related complications and mortality. METHODS: Swiss multicentre prospective observational study collecting demographic, anthropometric, and catheter-related data by means of questionnaires every sixth month from 2017 to 2019 (24 months), focusing on survival and complications. Data were analysed using descriptive statistics. Logistic regression models were fitted to investigate association between infection and potential co-factors. RESULTS: Seventy adult patients (50% women) on HPN were included (≈5 patients/million adult inhabitants/year). The most common underlying diseases were cancer (23%), bariatric surgery (11%), and Crohn's disease (10%). The most prevalent indication was short bowel syndrome (30%). During the study period, 47% of the patients were weaned off PN; mortality rate reached 7% for a median treatment duration of 1.31 years. The rate of catheter-related infection was 0.66/1,000 catheter-days (0.28/catheter-year) while the rate of central venous thrombosis was 0.13/1,000 catheter-days (0.05/catheter-year). CONCLUSION: This prospective study gives a comprehensive overview of the adult Swiss HPN patient population. The collected data are prerequisite for evaluation, comparison, and improvement of recommendations to ensure best treatment quality and safety.

Clinical characteristics and predictive factors of survival of 761 cancer patients on home parenteral nutrition: A prospective, cohort study.

BACKGROUND: Robust data reporting the survival of cancer patients on home parenteral nutrition (HPN) are lacking. The aim of this prospective, cohort study was to investigate clinical characteristics, predictive factors, and overall survival (OS) of adult-malnourished cancer patients eligible for HPN according to the European guideline recommendations. METHODS: During the study period, 1658 cancer patients were consecutively evaluated in a tertiary university hospital. Of these, 761 who received HPN were grouped into four cohorts according to the provision of supplemental PN (SPN) or total (TPN) and whether they received chemotherapy (CT+ or CT- ): SPN/CT+ (n = 376), TPN/CT+ (n = 99), SPN/CT- (n = 191), and TPN/CT- (n = 95). Patient demographics, nutritional status, cancer-related characteristics, and prognostic scores assessed at HPN start. The primary outcome was OS. RESULTS: Median OS was 8.9, 4.3, 5.7, and 2.2 months for the SPN/CT+ , TPN/CT+ , SPN/CT- , and TPN/CT- cohorts, respectively. In multivariable analysis, predictors showing significant association with decreased survival were patient cohorts, modified Glasgow Prognostic Score (1 and 2 scores), weight loss (>15%) in the 3 months before HPN start, and TNM IV stage while protective factors of survival were Karnofsky Performance Status (>50), albumin level (>3.5 g/dL), oral protein intake, BMI (>20.5), and weight at HPN start. CONCLUSION: For the first time, in four different cohorts of cancer patients on HPN, clinical characteristics and survival were compared. This large study showed that survival is significantly correlated with patient characteristics at HPN start and that the presence of favorable factors may determine even a fourfold increase in survival. These data are expected to assist physicians in the appropriate prescription of HPN.

Home artificial nutrition in palliative care cancer patients: Impact on survival and performance status.

BACKGROUND AND AIMS: The prevalence of malnutrition is over 70% in advanced cancer patients and impacts negatively on survival and quality of life. Artificial nutrition can be integrated into a home palliative care program. This observational study aims to describe the criteria for identifying the cancer patients that could benefit from home artificial nutrition (HAN) and to evaluate its impact on survival and performance status. METHODS: The selection criteria for patient's eligibility to HAN were: Karnofsky Performance Status (KPS) ≥40, life expectancy ≥6 weeks, inadequate caloric intake ± malnutrition, suitable psycho-physical conditions and informed consent. The access route for nutritional therapy (home parenteral nutrition, HPN; home enteral nutrition, HEN) was chosen according to the ESPEN Guidelines. The parameters considered were: primary site of the tumor; oral food intake; nutritional status; stage of cachexia; fluid, energy and protein supplied by HAN; survival. RESULTS: From 1990 to 2019, 43,474 cancer patients were assisted at home in Bologna (Italy). HAN started in 969 patients (2.2% of total patients, 571 men and 398 women, mean age 65.7 ± 12.7 years): HPN in 629 patients (64.9%), with gastrointestinal obstruction as the main indication; HEN in 340 patients (35.1%), with dysphagia as the main indication. Considering the 890 deceased patients, the mean survival after the start of HAN was 18.3 weeks and 649 patients (72.9%) survived more than 6 weeks. The mean survival was higher in HEN (22.1 weeks) compared to HPN patients (16.1 weeks) (p < .001). After one month, KPS was unchanged in 649 (67.0%), increased in 232 (23.9%) and decreased in 88 patients (9.1%). The mean KPS increased in patients starting HAN in pre-cachexia and cachexia (p < .001). Cachexia and refractory cachexia at the entry were associated with a reduced survival [odds ratio: 1.5 and 2.3 respectively, p < .001 for both condition] respect to pre-cachexia. CONCLUSIONS: The selection criteria allow the identification of the patient who can take advantage of HAN. HAN can be effective in avoiding death from malnutrition in 73% of patients, and in maintaining or improving the KPS at one month in 90% of cases. The benefits provided by HAN on survival and performance status depend on the cachexia degree at the entry.

Variations in practice patterns for adult cancer patients on home parenteral nutrition in Canada.

OBJECTIVES: Cancer has become a major indication for home parenteral nutrition (HPN). However, the use of HPN in adult cancer patients is highly variable between countries and may also differ within each country. The aim of the present study was to characterize regional variations in practice patterns for cancer patients on HPN using data from the Canadian HPN Registry. METHODS: This retrospective analysis included all cancer patients (n = 164) enrolled in the registry from 2005 to 2016. Patient demographic and clinical characteristics were described. Differences in baseline characteristics were evaluated by province and duration of HPN therapy. Survival was estimated with the Kaplan-Meier method and compared among different tumor types and provinces using the log-rank test. RESULTS: The most common tumors were gastrointestinal (54.2%) and gynecologic (31.8%). Most patients were from the provinces of Ontario (54.3%) and Alberta (41.5%). Patients who received HPN for ≥3 mo (64.6%) had a higher baseline Karnofsky Performance Status (80 versus 50) and albumin (35 versus 26 mmol/L) compared with those on HPN for <3 mo. There were no differences in survival based on tumor category. Patients in Ontario programs had a longer median survival (11.3 versus 7.1 mo) and higher proportion of secondary indications for HPN relative to patients in Alberta programs. CONCLUSIONS: Most cancer patients on HPN have gastrointestinal or gynecologic cancers. Those surviving for ≥3 mo have better baseline characteristics. Regional variability in the prevalence, selection, and survival of cancer patients receiving HPN suggests the need for consensus on the use of HPN in this population.

Bioelectrical impedance analysis for monitoring cancer patients receiving chemotherapy and home parenteral nutrition.

BACKGROUND: Home parenteral nutrition (HPN) can improve survival, quality of life, nutritional and functional status in cancer patients. Bioelectrical impedance analysis (BIA) is a non-invasive, validated method to assess body composition. The objective of this prospective single-arm study was to investigate the impact of HPN in advanced cancer patients receiving chemotherapy assessed by BIA, clinical and laboratory measures. METHODS: Adult malnourished cancer outpatients with solid tumors receiving anticancer treatments who were candidates for daily HPN were enrolled. Patients were assessed at baseline (T0), 60 (T1) and 90 days (T2) after HPN start. Assessments included anthropometric and clinical-oncological characteristics, performance status, inflammatory response and Patient-Generated Subjective Global Assessment (PG-SGA). RESULTS: Sixty-five advanced cancer patients were enrolled. Median overall survival was 317 days. Body weight, BMI, oral calorie and protein intake increased over time (P < 0.01). At T2 the proportion of well-nourished patients, Karnofsky performance status and modified Glasgow prognostic score were improved (P < 0.01), total body water was reduced (P = 0.04), and fat mass increased (P = 0.04). Reactance, resistance and phase angle were significantly associated with survival at T0, T1, and T2, respectively. At T2, PG-SGA category A was a predictor of survival (P < 0.0001). CONCLUSIONS: After 90 days of HPN, patients experienced significantly improved nutritional status, performance status, prognostic score and some BIA measures. HPN may be an important therapy in oncology patients receiving chemotherapy. Longitudinal use of BIA may help track the effects of HPN and disease progression, potentially contributing to optimal global patient management.

Home parenteral nutrition for people with inoperable malignant bowel obstruction.

BACKGROUND: People with advanced ovarian or gastrointestinal cancer may develop malignant bowel obstruction (MBO). They are able to tolerate limited, if any, oral or enteral (via a tube directly into the gut) nutrition. Parenteral nutrition (PN) is the provision of macronutrients, micronutrients, electrolytes and fluid infused as an intravenous solution and provides a method for these people to receive nutrients. There are clinical and ethical arguments for and against the administration of PN to people receiving palliative care. OBJECTIVES: To assess the effectiveness of home parenteral nutrition (HPN) in improving survival and quality of life in people with inoperable MBO. SEARCH METHODS: We searched the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1), MEDLINE (Ovid), Embase (Ovid), BNI, CINAHL, Web of Science and NHS Economic Evaluation and Health Technology Assessment up to January 2018, ClinicalTrials.gov (http://clinicaltrials.gov/) and in the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal (http://apps.who.int/trialsearch/). In addition, we handsearched included studies and used the 'Similar articles' feature on PubMed for included articles. SELECTION CRITERIA: We included any studies with more than five participants investigating HPN in people over 16 years of age with inoperable MBO. DATA COLLECTION AND ANALYSIS: We extracted the data and assessed risk of bias for each study. We entered data into Review Manager 5 and used GRADEpro to assess the quality of the evidence. MAIN RESULTS: We included 13 studies with a total of 721 participants in the review. The studies were observational, 12 studies had only one relevant treatment arm and no control and for the one study with a control arm, very few details were given. The risk of bias was high and the certainty of evidence was graded as very low for all outcomes. Due to heterogeneity of data, meta-analysis was not performed and therefore the data were synthesised via a narrative summary.The evidence for benefit derived from PN was very low for survival and quality of life. All the studies measured overall survival and 636 (88%) of participants were deceased at the end of the study. However there were varying definitions of overall survival that yielded median survival intervals between 15 to 155 days (range three to 1278 days). Three studies used validated measures of quality of life. The results from assessment of quality of life were equivocal; one study reported improvements up until three months and two studies reported approximately similar numbers of participants with improvements and deterioration. Different quality of life scales were used in each of the studies and quality of life was measured at different time points. Due to the very low certainty of the evidence, we are very uncertain about the adverse events related to PN use. Adverse events were measured by nine studies and data for individual participants could be extracted from eight studies. This revealed that 32 of 260 (12%) patients developed a central venous catheter infection or were hospitalised because of complications related to PN. AUTHORS' CONCLUSIONS: We are very uncertain whether HPN improves survival or quality of life in people with MBO as the certainty of evidence was very low for both outcomes. As the evidence base is limited and at high risk of bias, further higher-quality prospective studies are required.

Point Prevalence of Adult Intestinal Failure in Republic Of Ireland.

Parenteral Nutrition (PN) is a life-saving treatment used for patients with Intestinal Failure (IF). PN is complex and demands highly specialised care to avoid serious complications in the home setting. All tertiary centres in the Republic of Ireland (ROI) were contacted to assess the prevalence of IF requiring PN and complications, over a one year period. Sixty-seven patients were treated across 15 centres: a period prevalence of 14.6 and 9.6 patients per million for long-term PN and home PN respectively. Three-quarters of patients experienced at least one major complication with 18% mortality rate over the study period. There were 2.86 admissions per HPN patient, each lasting mean 13.4 days. One-third experienced catheter-related infections. There was a reduced length of stay during emergency re-admissions in high volume centres (mean 31 v 43 days, p=0.17). The establishment of a National Centre for IF/HPN in ROI is integral to reducing PN-associated complications.

Intestinal failure: the evolving demographic and patient outcomes on home parenteral nutrition.

AIM: We performed this study to examine and understand the evolving demographics and changing outcomes of intestinal failure (IF) and its implications for healthcare delivery. METHOD: We conducted a retrospective analysis of outcome data of children on home parenteral nutrition (HPN), over a 15-year period. RESULTS: A total of 31 patients received HPN: 15 for short bowel syndrome (SBS), eight neuromuscular disease (NMD) and eight for other causes. The HPN prevalence increased from 1.54 per million children in 2000 to 21.5 in 2016. The outcomes over last 5 years were better than those of previous 10 years. The rate of catheter-related bloodstream infection (CRBSI) had fallen from 4 to 1.3 and IF liver disease (IFALD) from 20% to 7.7%. The aetiology changed over years from SBS being the main cause to NMD contributing 43% to the total in 2016. This was especially relevant as NMD was associated with greater numbers of IFALD (38% vs 6.7%), CRBSI (1.51 vs 0.64/1000 PN days) and mortality. CONCLUSION: The outcome of long-term parenteral nutrition (PN) has improved. The increasing number of patients with NMD, coupled with their higher burden of care, results in an increasing health care burden, and the planning of intestinal rehabilitation services needs to reflect this.

Home parenteral nutrition for advanced cancer patients: Contributes to survival?

OBJECTIVES: Patients with advanced cancer often suffer from severe malnutrition and gastrointestinal obstruction. This population could benefit from home parenteral nutrition (HPN). The aim of this study was to observe the outcome of patients with advanced cancer patients who were eligible for HPN. METHODS: All patients in the nutrition clinic who received HPN over the past 7 y were included in the present study. We compared patients with advanced cancer with the noncancer population in terms of hospitalization rate and mortality. RESULTS: Of 221 advanced cancer patients, 153 who had no oral/enteral intake and who received HPN survived. Of these, 35% survived for 6 mo, 27% for 1 y, 18.9% survived 2 y, and 3.9% survived for the 7 y of the follow-up. Hospitalization rate was not significantly different from the noncancer population. CONCLUSION: These results show that HPN is a relevant palliative therapy for patients with advanced cancer patients without oral or enteral feeding access.

Five-year survival and causes of death in patients on home parenteral nutrition for severe chronic and benign intestinal failure.

BACKGROUND & AIM: Home parenteral nutrition (HPN) is the primary treatment for chronic intestinal failure (IF). Intestinal transplantation (ITx) is indicated when there is an increased risk of death due to HPN complications or to the underlying disease. Age, pathophysiologic conditions and underlying disease are known predictors of HPN dependency and overall survival. Although the cause of death on HPN is mostly related to underlying disease in these patients, the relationship between mortality and duration of HPN use remains unclear. The purpose of the present study is to describe factors associated with survival and HPN dependency as well as causes of death in adult patients requiring HPN for chronic intestinal failure during the first 5 years of treatment with HPN. METHODS: A multicenter international (European and USA) questionnaire-based retrospective follow-up of a cohort of 472 IF patients who started HPN was conducted between June and December 2000. Study endpoint was either end of 5-year follow-up, weaned-off HPN, ITx, or death on HPN. Data were analyzed for HPN dependence and overall survival using Kaplan-Meier models and log rank tests. RESULTS: The overall survival probability was 88%, 74% and 64% at 1, 3 and 5 years respectively. Survival was inversely related to age (p < .001) and higher in patients with Crohn's disease or chronic idiopathic pseudo-obstruction. A total of 169 (36.5%) patients were weaned-off HPN mainly (80%) within the first year and most frequently in patients with fistulae. Five of the 14 patients who underwent ITx died. By the end of the study, 104 (23%) of patients died on HPN; 65% of deaths occurred within the first 2.5 years of HPN. CONCLUSIONS: Younger ages at HPN initiation and underlying pathologies are significantly predictive of survival on HPN. Risk of death is greatest during the first 2 years of HPN.

The influence of the initial state of nutrition on the lifespan of patients with amyotrophic lateral sclerosis (ALS) during home enteral nutrition

Aim: Amyotrophic lateral sclerosis (ALS) is a chronic, neurodegenerative disease, which leads to development of malnutrition. The main purpose of this research was to analyze the impact of malnutrition on the course of the disease and long-term survival. Material and methods: A retrospective analysis has been performed on 48 patients (22 F [45,83%] and 26 M [54,17%], the average age of patients: 66,2 [43-83]) in 2008-2014.The analysis of the initial state of nutrition was measured by body mass index (BMI), nutritional status according to NRS 2002, SGA and concentration of albumin in blood serum. Patients were divided into two groups, depending on the state of nutrition: well-nourished and malnourished. The groups were created separately for each of these, which allowed an additional comparative analysis of techniques used for the assessment of nutritional status. Results: Proper state of nutrition was interrelated with longer survival (SGA: 456 vs. 679 days, NRS: 312vs. 659vs. 835 days, BMI: respectively, 411, 541, 631 days, results were statistically significant for NRS and BMI). Concentration of albumin was not a prognostic factor, but longer survival was observed when level of albumin was increased during nutritional therapy. Conclusions: The initial nutrition state and positive response to enteral feeding is associated with better survival among patients with ALS. For this reason, nutritional therapy should be introduced as soon as possible.

Objetivo: la esclerosis lateral amiotrófica (ELA) es una enfermedad crónica, neurodegenerativa que genera malnutrición. El objetivo principal de este estudio es analizar el impacto de la malnutrición en el curso de la enfermedad y la sobrevida a largo plazo. Materiales y métodos: se realizó un análisis retrospectivo de 48 pacientes (22 mujeres [45.83%] y 26 hombres [54.17%], con un promedio de edad de 66,2 [43-83]) del 2008 al 2014. El análisis del estado nutricional inicial se midió utilizando el índice de  masa corporal (IMC), el estado nutricional de acuerdo al NRS 2002, la valoración global subjetiva (VGS) y la concentración sérica de albúmina. Los pacientes se dividieron en dos grupos, dependiendo del estado nutricional en el que se encontraban: bien nutridos o malnutridos. Los grupos se crearon por  separado, lo que permitió un análisis comparativo adicional de las técnicas utilizadas para la evaluación del estado nutricional. Resultados: un estado nutricional adecuado se relaciona con mayor sobreviva a largo plazo (456 vs. 679 días, NRS 312 vs. 659 vs. 835 días, IMC respectivamente: 41, 541, 631 días, resultados estadísticamente significativos para NRS e IMC). Las concentraciones de albúmina no fueron un factor pronóstico, pero se observó mayor sobrevida si las concentraciones de albúmina incrementaban durante el tratamiento nutricional. Conclusiones: el estado nutricional inicial y la respuesta positiva a la alimentación enteral están asociados a mayor sobrevida en pacientes con ELA, razón por la cual, la terapia nutricional debe de iniciarse lo antes posible.

Development and validation of a nomogram to predict survival in incurable cachectic cancer patients on home parenteral nutrition.

BACKGROUND: The use of home parenteral nutrition (HPN) in incurable cancer patients is extremely varied across different countries and institutions. In order to assess the clinical impact implied, we previously conducted a survey of incurable cancer patients receiving HPN, which shows that survival was markedly affected by Karnofsky performance status (KPS), tumor spread, Glasgow prognostic score (GPS) and tumor site. The aim of this study was to develop a nomogram incorporating the above factors for survival prediction. PATIENTS AND METHODS: We gathered a series of 579 patients, all receiving HPN, which was randomly split into a training and a testing sample. Using Cox proportional hazard regression modeling, a nomogram was built in the training sample, in order to estimate median survival or survival probability at 3 and 6 months according to individual patient characteristics. The nomogram performance was then verified in the testing sample. RESULTS: In the training sample, median survival was 3.2 (95% CI 3.0-3.7) months. GPS, KPS, tumor site and spread were confirmed to be significant prognostic factors. A significant interaction was also shown between the site and spread while weight loss (WL), adjusted for body mass index, failed to provide any substantial prognostic contribution. In the testing sample, nomogram performance was good in terms of calibration and discreet regarding discrimination. CONCLUSION: With the growing availability of new oncological treatments and their tendency to transform the trajectory of the advanced cancer into a chronic condition characterized by progressive WL and poor nutrients intake, an increasing number of patients are expected to receive HPN. In such a setting, tools for predicting the survival outcome may play a role toward personalized medicine and for investigating novel experimental therapies. Our proposed nomogram is a step forward in this direction but needs to be made stronger in order to definitely have clinical utility.

Home parenteral nutrition (HTPN) for incurable patients with cancer with gastrointestinal obstruction: do the benefits outweigh the risks?

Patients with cancer may suffer from malnutrition due to cachexia, this maybe secondary to treatment, psychological factors and/or gastrointestinal (GI) obstruction. GI obstruction indicates a need for TPN. Does this apply to patients with incurable terminal cancer? How does TPN affect longevity and quality of life in this group of patients? What is the course of TPN treatment compared with patients receiving TPN due to nonmalignant GI failure (NMGIF). The aim of this work was to help define the role of TPN in patients with incurable cancer and GI obstruction. Data of all patients treated by home TPN (HTPN) 2003-2009 were collected prospectively and analyzed. Sixty-eight patients were treated with HTPN, 30 of them for NMGIF. Mean age was 52 years (37-87). Primary sites of cancer were ovary (9), stomach (8) and others (11). Median survival of patients with malignant GI failure (MGIF) was 140 days (20-783) with no difference with regard to age, gender, primary diagnosis, BMI, percentage of weight loss and albumin level. Patients with MGIF and a higher performance score had longer survival. Patients with MGIF suffered significantly higher rates of overall and infectious complications per treatment days [P < 0.001]. TPN for MGIF incurable patients with cancer prolongs survival but at the cost of frequent complications. TPN is indicated in a selected group of MGIF. We do not have the tools to predict in which patients the benefits will outweigh the cost, but we found variables which may assist caregivers to make clinical and empathic decisions individually.

Long-term outcome of chronic intestinal pseudo-obstruction adult patients requiring home parenteral nutrition.

OBJECTIVES: Chronic intestinal pseudo-obstruction (CIPO) is a rare, disabling disorder responsible for motility-related intestinal failure. Because it induces malnutrition, CIPO is a significant indication for home parenteral nutrition (HPN). The objective of the study was to evaluate long-term outcome of CIPO patients requiring HPN during adulthood. METHODS: In total, 51 adult CIPO patients (18 men/33 women, median age at symptom occurrence 20 (0-74) years, 34/17 primary/secondary CIPO) followed up at our institution for HPN management between 1980 and 2006 were retrospectively studied for survival and HPN dependence rates using univariate and multivariate analysis. RESULTS: Follow-up after diagnosis was 8.3 (0-29) years. Surgery was required in 84% of patients. The number of interventions was 3 +/- 3 per patient (mean +/- s.d.), leading to short bowel syndrome in 19 (37%) patients. Actuarial survival probability was 94, 78, 75, and 68% at 1, 5, 10, and 15 years, respectively. Multivariate analysis showed that lower mortality was associated with the ability to restore oral feeding at baseline (hazard ratio (HR) = 0.2 (0.06-0.65), P = 0.008) and symptom occurrence before the age of 20 years (HR=0.18 (0.04-0.88), P = 0.03). Higher mortality was associated with systemic sclerosis (HR=10.4 (1.6-67.9), P = 0.01). Actuarial HPN dependence was 94, 75, and 72% at 1, 2, and 5 years, respectively. CONCLUSIONS: In this large cohort of CIPO adult patients with severe intestinal failure, i.e., those requiring HPN, we found a higher survival probability than previously reported. These results should be taken into account when considering intestinal transplantation.

Survival of patients identified as candidates for intestinal transplantation: a 3-year prospective follow-up.

BACKGROUND & AIMS: The US Medicare indications for intestinal transplantation are based on failure of home parenteral nutrition. The American Society of Transplantation also includes patients at high risk of death from their primary disease or with high morbidity intestinal failure. A 3-year prospective study evaluated the appropriateness of these indications. METHODS: Survival on home parenteral nutrition or after transplantation was analyzed in 153 (97 adult, 56 pediatric) candidates for transplantation and 320 (262 adult, 58 pediatric) noncandidates, enrolled through a European multicenter cross-sectional survey performed in 2004. Kaplan-Meier and chi-square test statistics were used. RESULTS: The 3-year survival was 94% (95% CI, 92%-97%) in noncandidates and 87% (95% CI, 81%-93%) in candidates not receiving transplants (P = .007). Survival was 80% (95% CI, 70%-89%), 93% (95% CI, 86%-100%), and 100% in parenteral nutrition failure, high-risk primary disease, and high-morbidity intestinal failure, respectively (P = .034). Fifteen candidates underwent transplantation. Six died, including all 3 of those who were in hospital, and 25% of those who were at home at time of transplantation (P = .086). Survival in the 10 patients receiving a first isolated small bowel transplant was 89% (95% CI, 70%-100%), compared with 85% (95% CI, 74%-96%) in the candidates with parenteral nutrition failure not receiving transplants because of central venous catheter complications, or 70% (95% CI, 53%-88%) in those with parenteral nutrition-related liver failure (P = .364). CONCLUSIONS: The results confirm home parenteral nutrition as the primary therapeutic option for intestinal failure and support the appropriateness and potential life-saving role of timely intestinal transplantation for patients with parenteral nutrition failure.

[Spanish Registry of Home-based Parenteral Nutrition during 2006 (NADYA-SENPE Group)]. / Registro de la Nutrición Parenteral Domiciliaria (NPD) en España del año 2006 (Grupo NADYA-SENPE).

OBJECTIVE: To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the year 2006. METHODOLOGY: We compiled the data from the on-line registry introduced by the responsible Units for the monitoring of HPN from January 1st to December 31st 2006. RESULTS: 103 patients with HPN were registered (47 males and 56 females), belonging to 19 hospitals. Average age for the 91 patients older than 14 years old was 53.3 +/- 14.9 years old, and that for the 12 patients under 14 years old was 2 +/- 0 years old. Most frequent pathology was neoplasm (29%), followed by intestinal motility disorders (13%). The reason for HPN provision was short bowel syndrome (40%), intestinal obstruction (22%), and malabsorption (21%). Tunneled catheters were mostly used (45%), followed by implanted port-catheters (32%). Catheter related infections were the most frequent complications, with a rate of 0.85 episodes / 10(3) days. HPD was provided for more than two years in 50% of the cases. By the end of 2006, 70.9% of the patients remained active; exitus was the most frequent reason to end HPN (53%). Complementary oral or enteral nutrition was provided to 52% of the patients. 48% of the patients had a normal activity level, and a 55% were autonomous. PN formula was supplied by the hospital in 82% of the cases, while this number was 78% for fungible materials. 27% of the patients were eligible for intestinal transplant. CONCLUSIONS: We observe an increase in registered patients with respect to previous years, with a very different prevalence among regions. Neoplasia remains as the main pathology since 2003. We observe a decrease in catheter-related infections with respect to the 2004-2005 period.

Long-term outcome of children receiving home parenteral nutrition: a 20-year single-center experience in 302 patients.

BACKGROUND: More information is needed regarding the prognosis of children receiving home parenteral nutrition (HPN). This article describes 20-year outcome data in children receiving HPN and provides separate profiles for the major pediatric diagnostic subgroups. PATIENTS AND METHODS: This retrospective study included children who started receiving HPN between January 1, 1980, and December 31, 1999, in a single pediatric HPN center. RESULTS: A total of 302 children were recruited, 230 (76%) with primary digestive disorders and 72 (24%) with nonprimary digestive disorders. Median age at HPN onset was 1.5 years. Median duration of HPN was 1.3 years. By January 1, 2000, 54% had weaned from HPN, 26% were still receiving HPN, 16% had died, and 4% had undergone intestinal transplantation. The survival probabilities at 2, 5, 10, and 15 years were 97%, 89%, 81%, and 72%, respectively. The likelihood and cause of death depended on the underlying diagnosis. Nine percent of children with primary digestive disorders died, 24% from their primary disease and 48% from liver disease or sepsis. Children with intractable diarrhea of infancy had the highest mortality rate (25%) and the highest incidence of liver disease (48%; P = 0.0002). Thirty-eight percent of children with primary nondigestive diseases died, 94% from their primary disease and 6% from liver disease or sepsis. CONCLUSIONS: Outcome and survival of children receiving HPN are mainly determined by their underlying diagnosis. Nearly all children with primary digestive disease survive if referred early to an expert center.

[Quality of the home parenteral nutrition program: 14 years of experience at a general university hospital]. / Calidad del programa de nutrición parenteral a domicilio: 14 años de experiencia en un hospital general universitario.

The quality of home parenteral nutrition (NPD in its Spanish acronym) depends on the frequency and type of complication associated with NPD treatment and the likelihood of survival. The present study assesses the quality of the NPD programme in place in our hospital in terms of survival, infections and mechanical complications. A retrospective study was carried out into the clinical follow-up data of all the patients (n = 24) included in our NPD programme since its start in 1985 until 1998 (14 years). An estimate is made for: a) the annual index of infectious complications (IAC in its Spanish acronym), b) the annual index of mechanical complications (MAC in its Spanish acronym) and c) the likelihood of survival by means of the Kaplan-Meier method. The quality specifications adopted are those of the literature reflecting the current provision of NPD programmes and the survival values of patients undergoing dialysis for chronic kidney failure. The most frequent pathology in our context is benign (70.8%), distributed as follows: small bowel syndrome of ischaemic origin (45.8%), small bowel syndrome of non-ischaemic origin (12.5%) and idiopathic intestinal pseudo-obstruction (12.5%). The patients with benign pathologies present a higher survival rate than patients with neoplastic disease (95% in the fifth year of treatment versus 45% at twenty months), with a statistically significant difference. The annual index of infectious complications is 0.6 (median value of the 14 years studied). Similarly, the annual indices of obstructions and thromboses are 0.11 and 0.0095, respectively. In our opinion, the quality of the NPD programme in place at our hospital is highly satisfactory because both the survival rate and the annual indices of mechanical and infectious complications are acceptable with regard to the programmes in place in the international sphere. In addition, in terms of survival, NPD seems slightly more effective than dialysis for chronic kidney disease.
