No full textButyrate as an effective treatment of congenital chloride diarrhea
No full textBackground & Aims: Many therapeutic attempts have demonstrated to be ineffective in reducing the severity of congenital chloride diarrhea and its long-term complications. The short-chain fatty acid butyrate stimulates intestinal water and ion absorption through a variety of mechanisms, including the activation of a parallel Cl -/butyrate and Na +/H + exchanger. In this case report, we report the therapeutic efficacy of butyrate on an 11-year-old patient affected by congenital chloride diarrhea. Methods: The efficacy of increasing doses of oral butyrate (from 50 to 100 mg/kg/day) was investigated through the daily evaluation of stool volume, bowel movements, fecal incontinence, serum, and stool electrolytes concentrations. The modifications in transepithelial intestinal ion transport elicited by butyrate were examined by rectal dialysis study. Results: A butyrate dose of 100 mg/kg/day induced a normalization of stool pattern and of serum and fecal electrolytes concentration. The rectal dialysis study demonstrated a proabsorptive effect induced by butyrate on Na +, Cl -, and K + intestinal transport. Butyrate therapy was well tolerated during the entire 12-month observation period, and the stool pattern and fecal and serum ion concentrations remained stable within the normal ranges. No clinical adverse events or episodes of dehydration requiring hospital care were observed. Conclusions: Butyrate could be effective in treating congenital chloride diarrhea. It is easily administered, useful in preventing severe dehydration episodes, and may be a promising therapeutic approach for a long-term treatment in this rare and severe condition

Calcium and vitamin D intakes in children: a randomized controlled trial
No full textBackground: Calcium (Ca2+) and vitamin D (VitD) play an important role in child health. We evaluated the daily intake of Ca2+ and VitD in healthy children. Moreover, we demonstrate the efficacy of Ca2+ and VitD supplementation. Methods: Daily Ca2+ and VitD intake was evaluated in consecutive healthy children through a validated questionnaire. Subjects with = 30 ng/ml) was observed in all children in Group 1 and in only one subject in Group 2 [Group 1: T1 33.8 ng/ml (IQR 2.5) vs Group 2: T1 24.5 ng/ml (IQR 5.2), p < 0.001]. Conclusions: Adequate Ca2+ and VitD intakes are difficult to obtain through dietary counseling alone in pediatric subjects. Oral supplementation with of Ca2+ and VitD is a reliable strategy to prevent this condition

Treatment of low bone density in young people with cystic fibrosis: a multicentre, prospective, open-label observational study of calcium and calcifediol followed by a randomised placebo-controlled trial of alendronate.
No full textSummary Background Long-term complications of cystic fibrosis include osteoporosis and fragility fractures, but few data are available about effective treatment strategies, especially in young patients. We investigated treatment of low bone mineral density in children, adolescents, and young adults with cystic fi brosis. Methods We did a multicentre trial in two phases. We enrolled patients aged 5-30 years with cystic fi brosis and low bone mineral density, from ten cystic fi brosis regional centres in Italy. The fi rst phase was an open-label, 12-month observational study of the eff ect of adequate calcium intake plus calcifediol. The second phase was a 12-month, double-blind, randomised, placebo-controlled, parallel group study of the effi cacy and safety of oral alendronate in patients whose bone mineral apparent density had not increased by 5% or more by the end of the observational phase. Patients were randomly assigned to either alendronate or placebo. Both patients and investigators were masked to treatment assignment. We used dual x-ray absorptiometry at baseline and every 6 months thereafter, corrected for body size, to assess lumbar spine bone mineral apparent density. We assessed bone turnover markers and other laboratory parameters every 3-6 months. The primary endpoint was mean increase of lumbar spine bone mineral apparent density, assessed in the intention-totreat population. This study is registered with ClinicalTrials.gov, number NCT01812551. Findings We screened 540 patients and enrolled 171 (mean age 13.8 years, SD 5.9, range 5-30). In the observational phase, treatment with calcium and calcifediol increased bone mineral apparent density by 5% or more in 43 patients (25%). 128 patients entered the randomised phase. Bone mineral apparent density increased by 16.3% in the alendronate group (n=65) versus 3·1% in the placebo group (n=63; p=0.0010). 19 of 57 young people (33.3%) receiving alendronate attained a normal-for-age bone mineral apparent density Z score. In the observational phase, fi ve patients had moderate episodes of hypercalciuria, which resolved after short interruption of calcifediol treatment. During the randomised phase, one patient taking alendronate had mild fever versus none in the placebo group; treatment groups did not diff er signifi cantly for other adverse events. Interpretation Correct calcium intake plus calcifediol can improve bone mineral density in some young patients with cystic fi brosis. In those who do not respond to calcium and calcifediol alone, alendronate can safely and eff ectively increase bone mineral density. Funding Telethon Foundation (Italy)
