Efficacy of ginger as antiemetic in children with acute gastroenteritis: a randomised controlled trial.

BACKGROUND: Ginger is a spice with a long history of use as a traditional remedy for nausea and vomiting. No data on the efficacy of ginger are presently available for children with vomiting associated with acute gastroenteritis (AGE). AIM: To test whether ginger can reduce vomiting in children with AGE. METHODS: Double-blind, randomised placebo-controlled trial in outpatients aged 1 to 10 years with AGE-associated vomiting randomised to ginger or placebo. The primary outcome was the occurrence of ≥1 episode of vomiting after the first dose of treatment. Severity of vomiting and safety were also assessed. RESULTS: Seventy-five children were randomised to the ginger arm and 75 to the placebo arm. Five children in the ginger arm and 4 in the placebo arm refused to participate in the study shortly after randomisation, leaving 70 children in the ginger arm and 71 in the placebo arm (N = 141). At intention-to-treat analysis (N = 150), assuming that all children lost to follow-up had reached the primary outcome, the incidence of the main outcome was 67% (95% CI 56 to 77) in the ginger group and 87% (95% CI 79 to 94) in the placebo group, corresponding to the absolute risk reduction for the ginger versus the placebo group of -20% (95% CI -33% to -7%, P = 0.003), with a number needed to treat of 5 (95% CI 3 to 15). CONCLUSION: Oral administration of ginger is effective and safe at improving vomiting in children with AGE. TRIAL REGISTRATION: The trial was registered on https://clinicaltrials.gov/ with the identifier NCT02701491.

One-year glargine treatment can improve the course of lung disease in children and adolescents with cystic fibrosis and early glucose derangements.

BACKGROUND: Diabetes increases morbidity and mortality in cystic fibrosis (CF) patients, but several studies indicate that also prediabetic status may have a potential impact on both nutrition and lung function. OBJECTIVE: To evaluate the effect of glargine on the clinical course in CF patients with early glucose derangements. METHODS: CF population was screened for glucose tolerance. CF patients with age >10 yr were screened with fasting hyperglycemia (FH). CF patients with age >10 yr without FH and those with age <10 yr with occasional FH were evaluated for glucose abnormalities on the basis of oral glucose tolerance test and/or continuous glucose monitoring system. All CF patients with glucose derangements were enrolled in an open clinical trial with glargine. Body mass index (BMI) z-score, forced expiratory volume in the first second (FEV(1)), number of acute pulmonary exacerbations and hemoglobin A1c, were as outcome measures at baseline and after 1 yr of treatment. RESULTS: After 12 months of therapy, BMI z-score improved only in patients with baseline BMI z-score less than -1 (p = 0.017). An 8.8% increase in FEV(1) (p = 0.01) and 42% decrease in the number of pulmonary exacerbations (p = 0.003) were found in the whole group compared with previous 12 months of therapy. CONCLUSION: Glargine could represent an innovative strategy to prevent lung disease progression in CF patients with early glucose derangements. Larger controlled trials are needed to better clarify the effects of insulin on clinical status in CF patients with early glucose derangements.

Burkholderia cepacia complex infection in a cohort of Italian patients with cystic fibrosis.

The aims of this study were to detect Burkholderia cepacia complex (Bcc) strains in a cohort of Cystic Fibrosis patients (n=276) and to characterize Bcc isolates by molecular techniques. The results showed that 11.23% of patients were infected by Bcc. Burkholderia cenocepacia lineage III-A was the most prevalent species (64.3%) and, of these, 10% was cblA positive and 50% esmR positive. Less than half of the strains were sensitive to ceftazidime, meropenem, piperacillin tazobactam, and trimethoprim-sulfamethoxazole. About half of the strains (41%) had homogeneous profiles, suggesting cross-transmission. The infection by B. cenocepacia was associated to a high rate of mortality (p=0.01).

Preventive Effect of Cow's Milk Fermented with Lactobacillus paracasei CBA L74 on Common Infectious Diseases in Children: A Multicenter Randomized Controlled Trial.

Background: Fermented foods have been proposed to prevent common infectious diseases (CIDs) in children attending day care or preschool. OBJECTIVES: To investigate the efficacy of dietary supplementation with cow's skim milk fermented with the probiotic Lactobacillus paracasei CBA L74 in reducing CIDs in children attending day care or preschool. Methods: Multicenter, randomized, double-blind, placebo-controlled trial on healthy children (aged 12-48 months) consuming daily 7 grams of cow's skim milk fermented with L. paracasei CBA L74 (group A), or placebo (maltodextrins group B) attending day care or preschool during the winter season. The main outcome was the proportion of children who experienced ≥1 episode of CID during a 3-month follow-up. Fecal biomarkers of innate (α- and ß-defensins, cathelicidin) and acquired immunity (secretory IgA) were also monitored. Results: A total of 126 children (71 males, 56%) with a mean (SD) age of 33 (9) months completed the study, 66 in group A and 60 in group B. At intention to treat analysis, the proportion of children presenting ≥1 CID was 60% in group A vs. 83% in group B, corresponding to an absolute risk difference (ARD) of -23% (95% CI: -37% to -9%, p < 0.01). At per-protocol-analysis (PPA), the proportion of children presenting ≥1 CID was 18% in group A vs. 40% in group B, corresponding to an absolute risk difference (ARD) of -22% (95% CI: -37% to -6%, p < 0.01). PPA showed that the proportion of children presenting ≥1 acute gastroenteritis (AGE) was significantly lower in group A (18% vs. 40%, p < 0.05). The ARD for the occurrence of ≥1 AGE was -22% (95% CI: -37% to -6%, p < 0.01) in group A. Similar findings were obtained at PPA regarding the proportion of children presenting ≥1 upper respiratory tract infection (URTI), which was significantly lower in group A (51% vs. 74%, p < 0.05), corresponding to an ARD of -23% (95% CI: -40% to -7%, p < 0.01). Significant changes in innate and acquired immunity biomarkers were observed only in subjects in group A. Conclusions: Dietary supplementation with cow's skim milk fermented with L. paracasei CBA L74 is an efficient strategy in preventing CIDs in children.

Cow's milk and rice fermented with Lactobacillus paracasei CBA L74 prevent infectious diseases in children: A randomized controlled trial.

BACKGROUND & AIM: Fermented foods have been proposed for the prevention of infectious diseases. We evaluated the efficacy of fermented foods in reducing common infectious diseases (CIDs) in children attending daycare. METHODS: Prospective randomized, double-blind, placebo-controlled trial (registered under Clinical Trials.gov identifier NCT01909128) on healthy children (aged 12-48 months) consuming daily cow's milk (group A) or rice (group B) fermented with Lactobacillus paracasei CBA L74, or placebo (group C) for three months during the winter season. The main study outcome was the proportion of children who experienced at least one CID. All CIDs were diagnosed by family pediatricians. Fecal concentrations of innate (α- and ß-defensins and cathelicidin LL-37) and acquired immunity biomarkers (secretory IgA) were also evaluated. RESULTS: 377 children (193 males, 51%) with a mean (SD) age of 32 (10) months completed the study: 137 in group A, 118 in group B and 122 in group C. Intention-to-treat analysis showed that the proportion of children who experienced at least one CID was lower in group A (51.8%) and B (65.9%) compared to group C (80.3%). Per-protocol analysis showed that the proportion of children presenting upper respiratory tract infections was lower in group A (48.2%) and group B (58.5%) compared with group C (70.5%). The proportion of children presenting acute gastroenteritis was also lower in group A (13.1%) and group B (19.5%) compared with group C (31.1%). A net increase of all fecal biomarkers of innate and acquired immunity was observed for groups A and B compared to group C. Moreover, there was a negative association between fecal biomarkers and the occurrence of CID. CONCLUSION: Dietary supplementation with cow's milk or rice fermented with L. paracasei CBA L74 prevents CIDs in children attending daycare possibly by means of a stimulation of innate and acquired immunity.

Hyaluronic acid improves "pleasantness" and tolerability of nebulized hypertonic saline in a cohort of patients with cystic fibrosis.

INTRODUCTION: Inhaled hypertonic saline improves lung function and decreases pulmonary exacerbations in people with cystic fibrosis. However, side effects such as cough, narrowing of airways and saltiness cause intolerance of the therapy in 8% of patients. The aim of our study was to compare the effect of an inhaled solution of hyaluronic acid and hypertonic saline with hypertonic solution alone on safety and tolerability. METHODS: A total of 20 patients with cystic fibrosis aged 6 years and over received a single treatment regimen of 7% hypertonic saline solution or hypertonic solution with 0.1% hyaluronate for 2 days nonconsecutively after a washout period in an open crossover study. Cough, throat irritation, and salty taste were evaluated by a modified ordinal score for assessing tolerability; "pleasantness" was evaluated by a five-level, Likert-type scale. Forced expiratory volume in 1 second was registered before and after the end of the saline inhalations. RESULTS: All 20 patients (nine males, 11 females, mean age 13 years, range 8.9-17.7) completed the study. The inhaled solution of 0.1% hyaluronic acid and hypertonic saline significantly improved tolerability and pleasantness compared to hypertonic saline alone. No major adverse effects were observed. No difference was documented in pulmonary function tests between the two treatments. CONCLUSION: Hyaluronic acid combined with hypertonic saline solution may contribute to improved adherence to hypertonic saline therapy. Further clinical trials are needed to confirm our findings. Considering the extraordinary versatility of hyaluronic acid in biological reactions, perspective studies could define its applicability to halting progression of lung disease in cystic fibrosis.

Ursodeoxycholic acid treatment in patients with cystic fibrosis at risk for liver disease.

BACKGROUND: Meconium ileus has been detected as a risk factor for development of liver disease in cystic fibrosis, with influence on morbidity and mortality. AIMS: To evaluate the effect of early treatment with ursodeoxycholic acid in patients with cystic fibrosis and meconium ileus to prevent chronic hepatic involvement and to explore the potential role of therapy on clinical outcomes. METHODS: 26 cystic fibrosis patients with meconium ileus (16 M, mean age 8,4 years, range 3,5-9) were assigned to two groups: group 1 (14 patients) treated early with ursodeoxycholic acid (UDCAe); group 2 (12 patients) treated with ursodeoxycholic acid at the onset of cystic fibrosis liver disease (UDCAd). Anthropometric data, pulmonary function tests, pancreatic status, complications such as diabetes, hepatic involvement and Pseudomonas aeruginosa colonisation were compared among groups. RESULTS: A higher prevalence of cystic fibrosis chronic liver disease was observed in the UDCAd group with a statistically significant difference at 9 years of age (p<0.05). Chronic infection by P. aeruginosa was found in 7% of UDCAe and 33% of UDCAd (p<0.05). No differences were observed in nutritional status and other complications. CONCLUSIONS: Early treatment with ursodeoxycholic acid may be beneficial in patients at risk of developing cystic fibrosis chronic liver disease such as those with meconium ileus. Multicentre studies should be encouraged to confirm these data.

Chryseobacterium respiratory tract infections in patients with cystic fibrosis.

OBJECTIVES: To investigate the prevalence of infections by Chryseobacterium in a cohort of cystic fibrosis (CF) patients, to assess the antimicrobial susceptibility of these strains, to examine their DNA fingerprinting and to evaluate some clinical outcomes of patients infected by these bacteria. METHODS: Patients (300) attending a Regional Cystic Fibrosis Unit were enrolled in this study over 4 years. Natural or induced sputum samples were processed for microscopic and cultural tests. For phenotypic identification, automated and manual systems were used. For chemosusceptibility test, an automatic broth microdilution test and a disk-diffusion test were used and strains underwent DNA fingerprinting by pulsed-field gel electrophoresis (PFGE). RESULTS: Thirty-five strains of Chryseobacterium were isolated from 22 patients. These strains showed a broad-spectrum antimicrobial resistance, with activity only for trimethoprim-sulfamethoxazole and quinolones. PFGE profiles of all isolates were generally heterogeneous, suggesting independent circulation. CONCLUSIONS: This is the first report about clinical isolates of Chryseobacterium spp from CF patients in an Italian Centre. The infection by Chryseobacterium was not associated to a deterioration of pulmonary function and mortality: therefore, all patients infected by Chryseobacterium were co-infected by Pseudomonas aeruginosa and 3 of these were also co-infected by Burkholderia cepacia complex.

Cutaneous manifestations as presenting sign of autoimmune lymphoproliferative syndrome in childhood.

Autoimmune lymphoproliferative syndrome is a disorder due to a defect of lymphocyte apoptosis, whose clinical manifestations consist of hyperplasia of lymphoid tissues and autoimmune diseases. We report on a 26-month-old child who presented with frequent eruptions of weals and angioedema without any apparent triggering factor, who subsequently developed an erythematopapular rash with a histological pattern of a lymphoplasmacellular infiltrate. Familial anamnesis revealed a history of lymphoadenomegaly and massive spleen and liver enlargement in her sister. Functional and molecular analysis led to a diagnosis of type 1a autoimmune lymphoproliferative syndrome. Immunophenotyping of the cutaneous lesion revealed the presence of an inflammatory infiltrate with a considerably high number of Langerhans cells. Cutaneous features such as urticaria, angioedema and vasculitis in children with a personal and familial history of hyperplasia of lymphoid tissues may be a presenting sign of a systemic disease, such as autoimmune lymphoproliferative syndrome.
