Prevention and treatment of implanted central venous catheter (CVC) - related sepsis: a report after six years of home parenteral nutrition (HPN).

Catheter-related sepsis is a serious and common complication in patients receiving home parenteral nutrition (HPN). Prevention measures, prevalence of infections, types of agents and implanted central venous catheters (CVC), effectiveness of antibiotic therapy have been evaluated in 221 patients consecutively followed in our unit from January 1995 to December 2000. The clinical diagnosis of catheter-related infection was made using well-defined criteria. Patients were divided into two groups: A and B, receiving instructions with different modalities: standard (A) and detailed (B), respectively. Sixty CVC-related sepsis occurred in 32 (14%) patients. A multivariate analysis showed that the duration of HPN (P<0.001; OR=0.9), type of catheter (P=0.009; OR=0.12) and type of disease (P=0.033; OR=4.92) significantly influence catheter infection. The type of implanted CVC (159 port-a-cath in 153 patients and 71 tunnelled in 68) seems to affect the infection rate, this being lower in tunnelled (P=0.03). Infection rate was lower in B vs A group (P<0.001) with all types of catheters, suggesting the preventive role of very careful training. In particular, the incidence of CVC-related sepsis was 6/1000 days of HPN (i.e. 6/1000 days of catheterization) in Group A and 3/1000 in Group B. Systemic and antibiotic lock therapy was performed with an 83% successful rate. Gram-positive bacteria were the most frequent CVC infection agents, which are usually eradicated by antibiotic therapy lasting 7 days.

Prevalence of bone disease in patients on home parenteral nutrition.

BACKGROUND & AIMS: The epidemiology of bone disease in home parenteral nutrition (HPN) is unknown. The aim of this paper is to evaluate the prevalence and severity of reduced bone mineral density (BMD) in long-term HPN. DESIGN: Cross-sectional, multicentre study including patients who within the last 12 months had their BMD assessed by dual-energy-X-ray absorptiometry after at least 6 months of HPN. Data on bone pain and fractures, the primary gastrointestinal diseases, nutritional and rehabilitation status and HPN regimen were reviewed. Both the T-score (no. of SD below mean BMD of young subjects) and the Z-score (no. of SD from normal BMD values corrected for sex and age) were analysed. RESULTS: A T -score <-1 at any site of assessment was observed in 84% of the 165 patients enrolled (<or= -2.5 in 41%). Bone pain occurred in 35% and bone fracture in 10% of patients. Both T - and Z-scores were significantly lower in symptomatic patients. The frequency of bone disease was higher in post-menopausal women but did not differ among the subgroups of the primary diseases. Stepwise regression analysis showed the lumbar spine Z -score positively associated with the age at starting HPN and the femoral neck Z-score positively associated with the body mass index. CONCLUSIONS: Bone disease was present in most of the patients on HPN, was of severe degree in one-half of them and symptomatic in one-third. The BMD Z-score appeared predictive of the risk of fracture. The prevalence of bone disease did not differ between the various primary diseases. Age at starting HPN and body mass index appeared to be the major factors associated with BMD Z-scores.

[Clinical nutritional outcome in patients recovering in a psychiatric setting from severe protein-energy malnutrition of anorexia nervosa].

Protein energy malnutrition due to anorexia nervosa, either restrictive or bulimic, requires an integrated medical psychiatric intervention to be treated. The aim of this study was to evaluate the effectiveness of this integrated treatment in severely malnourished anorectic patients requiring to be hospitalized in Psychiatry Unit. Fifteen patients (14 females, 1 male, mean age 19.6 +/- 4.7 years, body mass index 14.0 +/- 1.9 kg/m2) 13 of whom affected by restrictive anorexia nervosa and 2 by bulimic anorexia nervosa, have been hospitalized in the Psychiatry Unit of the Federico II University Hospital, Naples from September 2000 to July 2003, always without requiring compulsory sanitary treatment. Hospitalization was due to failure of the outpatient treatment in all of them, complicated by uncontrolled weight loss in 7, hydroelectrolytic unbalance in 2, edema in 1 patient. All were hypotensive and 4 had marked bradycardia. Forced nutrition was never necessary. Enteral nutrition by nasogastric tube was prescribed in 4 patients, oral nutrition supplements with diet in 4 and only diet in the remaining 7. All patients received vitamin and mineral supplements, if necessary parenterally. A mild body weight increase and satisfactory normalization of biochemical parameters was obtained in all patients during hospitalization. Thereafter they were enrolled in an outpatient integrated medical/psychiatric protocol, including group therapy. Only in 1 case, a few months later, a second hospitalization was necessary. In conclusion, integrated medical psychiatric treatment represents an effective intervention also in severely malnourished anorectic patient requiring hospitalization.
