Does gastrostomy tube feeding in children with cerebral palsy increase the risk of respiratory morbidity?
(9/39)
BACKGROUND: Children with severe neurological impairment may have significant oral motor dysfunction and are at increased risk of nutritional deficiencies, poor growth, and aspiration pneumonia. Gastrostomy tube feeding is increasingly being used for nutritional support in these children. AIM: To examine the occurrence of respiratory morbidity before and after gastrostomy feeding tube insertion in children with severe neurological disabilities. METHODS: This study was nested in a longitudinal, prospective, uncontrolled, multicentre cohort study designed to investigate the outcomes of gastrostomy tube feeding in 57 children with severe neurological disabilities. Parents completed a questionnaire prior to (visit 1) and 6 and 12 months (visits 2 and 3) following the gastrostomy, detailing number of chest infections requiring antibiotics and/or hospital admission. RESULTS: Mean number of chest infections requiring antibiotics was 1.8 on visit 1 and 0.9 on visit 3. Hospital admissions for chest infections fell significantly from 0.5 to 0.09. CONCLUSION: This study provides no evidence for an increase in respiratory morbidity following insertion of a feeding gastrostomy in children with cerebral palsy. (+info)
Fluoride exposure and bone status in patients with chronic intestinal failure who are receiving home parenteral nutrition.
(10/39)
BACKGROUND AND OBJECTIVE: Metabolic bone disease is frequent in chronic intestinal failure. Because fluoride has a major effect on bones, the status of both fluoride and bone was studied in long-term home parenteral nutrition (HPN) patients. DESIGN: We studied 31 adults aged (x +/- SD) 56.3 +/- 15.1 y, mainly patients with short-bowel syndrome, who had been receiving HPN for >1 y. Bone mineral density (BMD) was measured by absorptiometry, and serum fluoride was measured by using a fluoride-sensitive electrode. All patients ate and drank ad libitum. HPN (3.4 +/- 1.2 times/wk) complemented oral nutrition. Potential explicative factors were estimated by using a linear regression model (mixed-effects model). RESULTS: Of 120 fluoride dosages (2-6/patient), 102 were above the upper normal limit (1.58 micromol/L) at the laboratory. Mean (+/- SD) daily fluoride supply was 8.03 +/- 7.71 mg (US adequate intake: 3.1 mg/d for women and 3.8 for men; tolerable upper normal limit: 10 mg/d); intravenous fluoride varied from 0.06 to 1.45 mg, and oral fluoride varied from 0.09 to 27.8 mg. Serum fluoride concentrations were correlated with creatinine clearance and fluoride supply. BMD was significantly lower in the femoral neck than in the spinal area. After adjustment for sex and the duration of HPN, only the effect of serum fluoride on spinal BMD was significant. Two patients had symptoms of fluorosis, eg, calcaneum fissures, interosseous calcifications, or femoral neck osteoporosis. CONCLUSIONS: In chronic intestinal failure, high intakes of fluoride are frequent because of the beverages ingested to compensate for stool losses. Hyperfluoremia has an effect on bone metabolism and may increase skeletal fragility. The consumption of fluoride-rich beverages for extended periods is therefore not advisable. (+info)
Survival and dependence on home parenteral nutrition: experience over a 25-year period in a UK referral centre.
(11/39)
BACKGROUND: Home parenteral nutrition (HPN) is the standard treatment for severe intestinal failure in the United Kingdom. AIM: To review long-term survival and ongoing HPN dependence of patients receiving HPN treated at a specialist UK referral centre. METHODS: Medical records of patients commenced on HPN between 1979 and 2003 were reviewed retrospectively. Regression analysis was employed to identify factors associated with poor prognosis. RESULTS: Case notes of 188 patients were reviewed. Overall probability of survival was 86%, 77%, 73% and 71% at 1, 3, 5 and 10 years after starting treatment. In multivariate analysis, association was seen between mechanism of intestinal failure and survival: short bowel syndrome associated with a favourable prognosis, and intestinal dysfunction, dysmotility and obstruction with poorer prognoses. There was an association between increasing age and poor prognosis, but increased mortality was also seen in the youngest age groups. Only 9% of deaths were due to complications of HPN. Continued HPN dependence was 89%, 87%, 84% and 84% at 1, 3, 5 and 10 years in survivors. CONCLUSIONS: Long-term survival of patients receiving HPN remains better than that reported after intestinal transplantation. Mortality predominantly relates to underlying disease rather than complications of HPN. (+info)
Home parenteral nutrition in chronic intestinal failure.
(12/39)
In children with severe failure of intestinal function, intravenous nutrition is at present the only treatment able to maintain adequate nutrition for prolonged periods of time. Over the last five years we have discharged 10 patients home on parenteral nutrition for a total of 25 patient years and here the outcome of these children is presented. Of the 10 patients, one has discontinued home parenteral nutrition (HPN), seven patients remain well, one patient has recently moved to the USA, and one patient has died after major abdominal surgery. All children had either normal or an accelerated rate of growth on HPN and developmentally all have progressed well. All the children over 5 years attend normal schools. The major complication of treatment was line sepsis with an overall rate of one episode in 476 days and a total of nine central lines (five patients) have required replacement giving an average line life of 680 days. For those children unfortunate enough to suffer from severe intestinal failure, HPN is preferable to prolonged hospital treatment and offers the chance of a good quality of life with prolonged survival.

Hypomagnesemia associated with chondrocalcinosis: a cross-sectional study.
(13/39)
OBJECTIVE: To determine an association between magnesium (Mg) depletion and chondrocalcinosis, which has been reported but not investigated in a cross-sectional study. METHODS: Prevalence of chondrocalcinosis was investigated in 144 individuals: 72 patients receiving home parenteral nutrition (HPN) compared with 72 age- and sex-matched controls. Presence of chondrocalcinosis was assessed by knee radiographs. Blood serum and globular Mg levels and 24-hour urinary Mg content were compared. RESULTS: Mean +/- SD age for both patients and controls was 51 +/- 17 years, and 51% in both groups were women. Mean duration of HPN was 6.4 years. Prevalence of chondrocalcinosis was markedly higher in patients receiving HPN than controls (16.6% versus 2.7%; P = 0.006, odds ratio [OR] 7.0, 95% confidence interval [95% CI] 1.45-66.1). Mean +/- SD serum and globular Mg levels were significantly lower in patients than controls (serum: 0.75 +/- 0.09 mmoles/liter versus 0.81 +/- 0.08 mmoles/liter, P = 0.0006; globular Mg: 1.8 +/- 0.31 mmoles/liter versus 2.0 +/- 0.35 mmoles/liter, P = 0.0003). Twenty-four-hour urinary Mg level was lower in patients than controls (mean +/- SD 3.85 +/- 1.50 mmoles versus 5.37 +/- 3.71 mmoles; P = 0.001). Prevalence of chondrocalcinosis was significantly higher in patients with a low serum Mg level (OR 13.5, 95% CI 2.76-127.3, P < 0.0001), with a similarly high but not significant occurrence of chondrocalcinosis in patients with a low globular Mg level (OR 4.09, 95% CI 0.603-20.26, P = 0.08) and in patients with a low 24-hour urinary Mg level (OR 3.9, 95% CI 0.77-16.34, P = 0.05). CONCLUSION: Long-lasting Mg depletion is strongly associated with chondrocalcinosis. (+info)
Home parenteral nutrition--an effective and safe long-term therapy for systemic sclerosis-related intestinal failure.
(14/39)
OBJECTIVES: To examine the outcome in patients with SSc requiring parenteral nutrition (PN), and to compare their clinical characteristics with those of other SSc patients and of patients requiring PN/home parenteral nutrition (HPN) for other conditions. METHODS: Retrospective review of SSc and Intestinal Failure Unit databases at a tertiary referral centre for SSc/national unit for intestinal failure over a 13-yr period. RESULTS: Eight patients with SSc requiring PN during the study period were identified (2 males, 6 females: median age at commencement of PN 51 yrs, range 42-56 yrs). All patients commencing PN had bacterial overgrowth and malabsorption not responding to antibiotic therapy. The median duration of PN therapy in the eight patients was 40 months (range 0.8-192 months). Between them the eight patients had a total of 13,851 catheter-use days and only two line infections (0.14/1000 catheter days), a lower rate of line infection than in other HPN-treated patients at Hope Hospital (0.52/1000 catheter days). Three patients died during the 13-yr period, none of causes related to their PN. Six were unable to manage their HPN regime themselves, mainly because of problems with hand function. CONCLUSIONS: Although patient numbers were small, our findings suggest that HPN can be safely and successfully used long-term in patients with SSc and should be considered for patients unable to maintain their nutritional status because of severe gastrointestinal involvement. Impaired hand function should not preclude SSc patients from receiving HPN: family members or community nurses may be trained in the care of the HPN line. (+info)

Oral nutrition in patients receiving home cyclic parenteral nutrition: pattern of substrate utilization.
(16/39)
Patients receiving cyclic home parenteral nutrition (PN) often have a significant oral caloric intake. This study describes the metabolic use of fuels, as assessed by indirect calorimetry, in eight stable, ambulatory, noncancerous, adult patients receiving glucose-based PN with (PN + oral) or without (PN only) a self-selected oral intake. Patients' weight was 91 +/- 2% (mean +/- SE) of ideal body weight, and fat mass was 22 +/- 5 and 31 +/- 2% of actual body weight in males and females, respectively. Under the PN-only regimen, providing 104 +/- 5% of predicted basal energy expenditure (BEE), patients were in equilibrium for energy and nitrogen balances. Oral supplementation (absorbed oral intake 80 +/- 5% of BEE) was associated with positive energy and nitrogen balances but also with nearly continuous net fat synthesis. We conclude that the glucose-based PN + mixed oral regimen enables the patients to face the increased energy requirements of everyday ambulatory life but is not associated with an optimal body composition in long-term PN patients.
