Background and aims : Home parenteral nutrition (HPN) is a life-saving treatment for patients affected by chronic intestinal failure (CIF). Both this clinical condition and its therapy require radical lifestyle modifications, affecting life quality and psychological balance in patients as well as family members. Patient psychological burden has rarely been taken into consideration, not to mention that of caregivers. This study aims to evaluate the levels of anxiety in CIF patients on HPN, and their caregivers, consequently determining their impact on the psychological and physical aspects. Methods: After a brief introductory interview, adult patients on HPN for CIF and their caregivers were asked to fill in the HAMA-A questionnaire. Results: Fifty patients and their respective caregivers were enrolled. Mean HAMA-A scores were similar in patients and caregivers and testified the presence of a mild to severe impact of CIF and HPN in both groups, with a significantly higher impact on female patients and caregivers. After adjusting age, education level, duration of CIF and HPN dependence, and degree of kinship, no differences were revealed in the scores. Conclusions: The study confirms that CIF patients on HPN and their caregivers have a significant anxiety burden independently from the duration of the disease, therefore needing appropriate support.

Background: Crohn's disease (CD) is a chronic inflammatory bowel disease frequently associated with malabsorption and secondary protein-energy malnutrition (PEM)., Methods: Biochemical and clinical data of 63 (34 females, 29 males) patients with PEM due to CD sent to our outpatient unit for nutritional evaluation were retrospectively analyzed. Patients were divided into two groups, according to disease activity. Thirty-eight patients (group A) had the active disease, and 25 patients (group B) suffered from malabsorption resulting from past intestinal resections due to CD. After a physical and hemato-biochemical evaluation at the first visit, all patients received disease-specific personalized dietetic indications. When indicated, oral nutritional supplements, oral/parenteral vitamins, micronutrients, and electrolytes, up to parenteral nutrition, were prescribed., Results: After 1, 3, and 6 months of nutritional therapy, body weight, body mass index (BMI), and serum butyryl-cholinesterase significantly improved in both groups. In 8 out of 13 (61.5%) patients with a cutaneous stoma, intestinal continuity was restored., Conclusions: This study confirms the effectiveness of nutritional rehabilitation and provides information on the time required for nutritional treatment in patients with CD, both during the acute phase and after malabsorption due to intestinal resection.

Patients with short bowel syndrome (SBS) on long-term home parenteral nutrition (HPN) chronically receive high fluid volumes directly into the right atrium (RA) through the superior vena cava. We retrospectively evaluated cardiac function measured by routine transthoracic echocardiography (TTE) in a population of 26 SBS patients on long-term HPN and compared their data on echocardiograph-derived right heart structure and function, with those of a control group of 26 patients also bearing a central venous catheter (CVC) for other reasons. Results showed that body weight and BMI were significantly higher in the control group. The echocardiographic estimate of RA pressure was higher in HPN patients than in controls ( p = 0.01). An increased estimate of RA pressure indicates the need to consider TTE in the follow-up of long-term HPN patients to detect functional impairment early.

Background: Septic pulmonary embolism (SPE) may be a frequently undetected complication of central venous catheter (CVC)-related bloodstream infections (CRBSIs)., Materials and Methods: The incidence of SPE was evaluated in a cohort of non-oncological patients on home parenteral nutrition (HPN) who were hospitalized for a CRBSI from January 2013 to December 2017. The main clinical, microbiological, and radiological features and the therapeutic approach were also described., Results: Twenty-three infections over 51,563 days of HPN therapy were observed, corresponding to an infection rate of 0.45/1000. In 10 out of the 23 cases (43.5%), pulmonary lesions compatible with SPE were identified., Conclusion: Our results demonstrated that a CRBSI can produce asymptomatic SPE with lung infiltrates in 43.5% of the cases, suggesting the need to check for secondary lung infections to choose the most appropriate antimicrobial therapy.

Background and Aims: The study compares the essential amino acid (EAA) composition of different parenteral nutrition (PN) mixtures with whey protein EAA profile and the theoretical daily EAA requirements (set by WHO/FAO/UNU or IAAO method). According to the individual EAA profile, the potential effect of several PN mixtures was evaluated on the skeletal muscle mass (SMM) of patients on home PN., Methods: Eight AA solutions and fifteen complete PN mixtures were considered. Twenty-nine clinically stable patients with short bowel syndrome on home total PN were retrospectively evaluated. SMM was estimated by bioelectrical impedance analysis., Results: The prescribed doses of EAA that showed a significant increase in home PN patients muscle mass were considerably greater than the theoretical ones, showing an EAA profile similar to whey protein. At the daily dose of 1 g of total AA s/kg body weight (BW), the considered PN mixtures mostly failed to improve SMM. Only prescribed doses which included more than 0.25 g/kg BW of total BCAA with at least 0.10 g/kg BW leucine, 0.08 g/kg BW isoleucine, and 0.06 g/kg BW methionine showed a significant increase in SMM., Conclusions: The theoretical daily requirement for each EAA was met by all considered PN solutions when the prescribed daily dose of total AAs was set at 1 g/kg BW. Nevertheless, our data suggest that only an increase in total BCAA, also richer in single AA leucine, isoleucine, and methionine, is associated with the maintenance and/or increase of SMM. According to these preliminary observations, we support the prescription of an EAA composition of PN mixtures close to that of whey protein for the preservation of SMM in patients on long-term total PN.
