Survival has frequently been studied and reported in patients with long term intestinal failure (IF). However, studies comparing the survival and mortality rates with the background population are rare. This study compares the survival in an adult IF, non-malignant, short bowel syndrome (SBS) cohort with a control group and with age- and sex-specific background mortality rates.Patients with SBS, defined by a small bowel length of 200 cm or less, due to non-malignant disease, were included and followed until death or censoring on 31 December 2017. Causes of deaths occurring during home parenteral support (HPS) were assessed by review of the charts. Each case was matched with ten controls from the background population according to year of HPS initiation, age, and sex, and their survival was compared. Furthermore, age- and sex-specific mortality rates of the background population were used to calculate the standardized mortality ratio (SMR) and excess mortality.After five years, patients who initiated HPS had a relative survival of 76%. The SMR was 5.0 and the excess mortality was 50 per 1000 years. HPS-related deaths were assessed to account for 11% of deaths during HPS and occurred with an incidence of 10 per 1000 years. The excess mortality was as low as 15 per 1000 years in cases aged less than 40 years. Patients weaning off HPS had a mortality rate closer to that expected in the background population.In adult patients with a non-malignant cause of SBS-IF, the excess mortality was 50 per 1000 years. However, HPS related deaths were rarely registered with an incidence of 10 HPS related deaths per 1000 HPS treatment years.

In patients with short bowel syndrome (SBS), severe malabsorption may cause a need for parenteral support and, by definition, these patients suffer from SBS intestinal failure. Absorption of oral medications is likely diminished in patients with SBS intestinal failure and higher than normal doses may be required to achieve sufficient pharmacologic effect. We investigated the prescription patterns and oral dosages in a well-defined population of patients with non-malignant SBS intestinal failure.This was a cross-sectional analysis based on a cohort of adult patients with SBS intestinal failure treated with home parenteral support and registered in 2016 at the Department of Gastroenterology at the Copenhagen University Hospital - Rigshospitalet. The patients' clinical data and prescription patterns were extracted from electronic medical and medications records.The patients in our cohort (n = 74) were primarily females (58%), the median age was 63 years (interquartile range (IQR): 52-72 years) and the median BMI was 22 kg/m2 (IQR: 19-26 kg/m2). Each patient was treated with a median of eight drugs (range: 1-20). Most (75%) of the medications were administered orally. Only codeine, levothyroxine and loperamide were prescribed in higher dosages than recommended in their product labelling. All medication-treated patients were prescribed between one and four different analgesics.In our single-centre cohort of patients with SBS intestinal failure, orally administered medications were generally prescribed in recommended dosages.none Trial registration.

Background The objective of this retrospective cohort study was to assess the frequency, duration, and causes of hospitalizations in patients receiving home parenteral support (HPS) due to short-bowel syndrome (SBS) of nonmalignant causes. Furthermore, we aimed to investigate potential risk factors and hypothesized that patients with the shortest remnant, functional, small bowel-hence, the highest need for HPS-would have the highest incidence of hospitalizations. Methods Patients with nonmalignant SBS who initiated HPS in the period from 1970 to 2016 from the Department of Gastroenterology, Rigshospitalet, Copenhagen, Denmark, were included. Information about demography, hospitalizations at the department, and duration of HPS was obtained from the Copenhagen intestinal failure database. Results Patients (n = 331) received HPS for a total of 1409.9 years in the period. Hospitalizations accounted for 6.6% of the time registered as HPS-dependent. The average patient was hospitalized for 5.7% (range 0%-82%) of the registered HPS days. The incidence of admissions was 2.5 per HPS year. The median length of stay was 7 days (range; 0-387). Catheter-related complications were the most frequently registered causes of admissions (35.2%), subsequently accounting for 31.3% of the total admission time. A Cox regression of admissions showed no significant influence of the remnant-bowel anatomy but identified the ability to administer HPS unaided as associated with a significantly reduced hazard. Conclusions This retrospective study illustrated that 6.6% of the provided HPS days were, in fact, spent hospitalized. Since admissions elsewhere were not accounted for, this may be an underestimation.

Background In patients with intestinal failure (IF), who are receiving home parenteral support (HPS), variations between centers in estimates of survival and HPS dependency often reflect differences in population characteristics. However, variations in methodology and adherence to model assumptions may further contribute. Objectives We investigated how differences in methodology affect estimates of outcomes in IF patients. Methods We applied different model assumptions and statistical methods to real-life outcome data from a well-characterized cohort of nonmalignant short bowel syndrome (SBS) patients. This retrospective study was based on extracts from the Copenhagen IF database and from the Danish death registry. Results Estimates of mortality varied substantially, depending on the study design and statistical method. The 5-y mortality rate obtained with the Kaplan-Meier (KM) method was estimated to be 10.1% higher if patients were only followed during HPS treatment, compared with follow-up regardless of HPS treatment. The 5-y cumulative incidence of weaning off HPS was overestimated by 4.4% when inappropriately using the KM method, instead of the cumulative incidence function. The 5-y survival rates in nonmalignant SBS-IF patients who initiated HPS were 89.1% for those aged younger than 40 y, 74.8% for patients aged 40-60 y, and 52.1% for those older than 60 y. A Cox regression analysis identified age and diagnoses other than inflammatory bowel disease as significant risk factors for mortality. For HPS dependency, bowel anatomy was significantly associated with the ability to wean off, and no patients without a colon and less than 100 cm remnant of the small bowel remained continuously weaned off and alive for one year. Conclusions The large variations in outcomes illustrated in this study emphasize the importance of the appropriate selection of statistical methods. A comparison between studies is problematic, due to differences in the methods employed.

Background Weaning from parenteral support is considered indirect evidence of intestinal adaptation in patients with short bowel syndrome (SBS), but direct evidence is lacking. The objective of this study was to examine if intestinal adaptation could be demonstrated as increase in intestinal absorption of energy and wet weight over time measured by repeated metabolic balance studies (MBSs) and to examine whether adaptation was determined by the anatomy of the remnant bowel. Methods We retrospectively analyzed data from 48 repeated MBSs performed in 13 adult patients with SBS. Results were presented graphically and interpreted. The interpatient and intrapatient heterogeneity was compared based on anatomy of the remnant bowel. Results The number of repeated MBSs ranged from 2 to 7, and time between last intestinal resection and MBS from 5 months to 18.1 years. In 6 patients, the first MBS was performed within 2 years after last resection, but only 1 patient had repeated MBSs within this period. Nine patients had an end jejunoileostomy, and 4 patients had a jejuno-colonic or ileo-colonic anastomosis. None of the patients had jejunoileal anastomosis with a preserved ileocecal valve. Interpatient and intrapatient heterogeneity of wet weight and energy absorption was larger in patients without colon in continuity. The wet weight and energy absorption data showed no tendency toward intestinal adaptation in any anatomical group. Conclusion We observed no signs of late-phase intestinal adaptation in this selected group of patients with SBS. Future prospective MBSs are needed to understand the time course and magnitude of intestinal adaptation.

BACKGROUND Progressive renal impairment, given by an annual decline in estimated glomerular filtration rate (eGFR), has been described in patients with intestinal failure (IF) receiving home parenteral support (HPS). The objective of this study was to examine changes in eGFR over 5 years following initiation of HPS treatment and to identify potential risk factors for loss of renal function. METHOD This retrospective database study investigates eGFR changes in nonmalignant IF patients discharged with HPS from Rigshospitalet, Copenhagen, in an 8-year period. RESULTS One year after HPS initiation, mean eGFR decreased by 15.3 ml/min/1.73 m2 . Paired t-test showed a decline of 15.0 ml/min/1.73 m2 (95% CI, -18.3 to -11.6; P < .0001). Over the following years, eGFR continued to decrease but at insignificant lower rates. Decreased eGFR was associated with increasing age, female sex, increasing body weight, diabetes at HPS initiation, and a high requirement of HPS volume. CONCLUSION In nonmalignant IF patients, the decrease of eGFR was mainly seen during the first year of HPS. This may be due to a higher risk of dehydration and possibly secondary hyperaldosteronism leading to renal damage following the onset of IF. However, the decrease in eGFR may also represent a higher production of creatinine due to a beneficial increase of muscle mass in the initial recovery phase. In general, once the patients were stabilized, the eGFR decline followed a physiological course resembling the background population. Patients with diabetes or high HPS volume needs seem to be more vulnerable and may require special attention.

Aim was to investigate the association between quality of life (QoL), bowel anatomy, and the need for home parenteral support (HPS) volume in patients with nonmalignant short-bowel syndrome (SBS) and intestinal failure (IF).The SBS-QoL scale was used in a cross-sectional study of 95 nonmalignant SBS-IF patients. Sum QoL scores (0: best, 170: worst) were calculated. Patients were defined as having a small bowel (≤200 cm), and patients with jejunostomy or ileostomy were subclassified based on functional small-bowel length (cm) into 4 anatomy subgroups: 1a-1d (0-49, 50-99, 100-149, 150-200 cm, respectively). Multiple linear regression analyses explored associations between QoL, patient groups, and HPS volume, adjusting for age, sex, body mass index, and education.Complete data were obtained from 60 patients. HPS volume was associated with a worse SBS-QoL score (L/d, β = 7.91; SE = 3.90; P = .048), but male sex associated with improvement (β = -26.28; SE = 11.06; P = .021). No differences in sum QoL were seen between the benign SBS-IF subgroups 1a-d (P = .210). Multivariate regression analyses showed that patients with a small-bowel stoma, a small-bowel length50 cm was associated with a significantly worse/higher SBS-QoL score compared with a length50 cm.In patients with benign SBS-IF, high HPS volume was associated with poor QoL. Also, jejunostomy or ileostomy with small-bowel length50 cm was associated with impaired QoL. These findings support rehabilitation strategies that reduce fecal losses and decrease HPS needs.

Weissella confusa is a Gram-positive coccus and a commensal bacterium of the human gastrointestinal tract with a potential to cause invasive infections. We report the presence of W. confusa in the blood of a 25-year-old male patient with Crohn’s disease, short bowel syndrome treated with home parenteral nutrition, and a history of recurrent bloodstream infections, admitted to our hospital with fever and malaise. A polymicrobial culture of W. confusa and Aeromonas hydrophila was identified from blood, for which treatment with meropenem and metronidazole was initiated. The literature was searched for previous cases of infection with W. confusa . In total, 14 reports describing infection of 28 patients were found, most cases presenting with bacteremia. The previous reports have described variable susceptibility to antibiotics; however, all were reported to be vancomycin resistant. Because of its similarities to other vancomycin-resistant cocci, isolates of W. confusa might be difficult to identify with traditional methods. Infection may be facilitated by its natural vancomycin resistance, leading to severe infection in hosts with underlying diseases. We describe the treatment of previous cases of infection and suggest treatment methods shown effective in other cases. Vancomycin is often used as treatment of infection with Gram-positive organisms, but this may need to be reevaluated, as several pathogenic bacteria are intrinsically vancomycin resistant. A review on reported treatments of bacteremia by W. confusa suggests the use of daptomycin, amoxicillin-clavulanate or piperacillin/tazobactam as recommendable antibiotic regimens.

Background: In patients with intestinal failure who are receiving home parenteral support (HPS), catheter-related bloodstream infections (CRBSIs) inflict health impairment and high costs.Objective: This study investigates the efficacy and safety of the antimicrobial catheter lock solution, taurolidine-citrate-heparin, compared with heparin 100 IE/mL on CRBSI occurrence.Design: Forty-one high-risk patients receiving HPS followed in a tertiary HPS unit were randomly assigned in a double-blinded, placebo-controlled trial. External, stratified randomization was performed according to age, sex, and prior CRBSI incidence. The prior CRBSI incidence in the study population was 2.4 episodes/1000 central venous catheter (CVC) days [95% Poisson confidence limits (CLs): 2.12, 2.71 episodes/1000 CVC days]. The maximum treatment period was 2 y or until occurrence of a CRBSI or right-censoring because of CVC removal. The exact permutation tests were used to calculate P values for the log-rank tests.Results: Twenty patients received the taurolidine-citrate-heparin lock and 21 received the heparin lock, with 9622 and 6956 treatment days, respectively. In the taurolidine-citrate-heparin arm, no CRBSIs occurred, whereas 7 CRBSIs occurred in the heparin arm, with an incidence of 1.0/1000 CVC days (95% Poisson CLs: 0.4, 2.07/1000 CVC days; P = 0.005). The CVC removal rates were 0.52/1000 CVC days (95% Poisson CLs: 0.17, 1.21/1000 CVC days) and 1.72/1000 CVC days (95% Poisson CLs: 0.89, 3.0/1000 CVC days) in the taurolidine-citrate-heparin and heparin arm, respectively, tending to prolong CVC survival in the taurolidine arm (P = 0.06). Costs per treatment year were lower in the taurolidine arm (€2348) than in the heparin arm (€6744) owing to fewer admission days related to treating CVC-related complications (P = 0.02).Conclusions: In patients with intestinal failure who are life dependent on HPS, the taurolidine-citrate-heparin catheter lock demonstrates a clinically substantial and cost-beneficial reduction of CRBSI occurrence in a high-risk population compared with heparin. This trial was registered at clinicaltrials.gov as NCT01948245.

Intestinal failure (IF) is the reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that parenteral support (PS) is required to maintain health and/or growth. This article critically revises the gaps in and evidence for providing general nutritional therapy recommendations in the Short Bowel Syndrome-IF population. It addresses the need for an individualized approach, aiming to reduce or even eliminate the need for PS, and emphasizes a need to focus on effects of dietary interventions on the quality of life of these patients.

Background In intestinal failure (IF) patients receiving home parenteral support (HPS), catheter-related bloodstream infections (CRBSIs) frequently result in replacement of their tunneled central venous catheters (CVCs), which may lead to future loss of central venous access. Objective This observational study investigated the consequences of a catheter-salvage strategy related to CRBSIs. Design All CRBSIs from 2002 to 2016 in the Copenhagen IF and microbiological databases were retrospectively analyzed. Catheter salvage was defined by successful antimicrobial therapy with a retained CVC at discharge. Re-occurrences of CRBSIs with the same microbial species and identical antibiogram were defined as a relapse (
