- چکیده انگلیسی: Recent studies have reported a relationship between vitamin D and atopic diseases such as asthma, allergic rhinitis, and atopic dermatitis, which is due to the recently discovered vitamin D receptors on many immune system cells. Among all atopic diseases, asthma has been studied the most in this regard. However, the role of vitamin D in other atopic diseases such as allergic rhinitis and atopic dermatitis is a matter of controversy. In this paper, we review the literature on the association between atopic diseases and vitamin D level with a focus on the childhood period. As of today, the role of vitamin D in atopic march is not clear and studies show controversial results. Therefore, further studies with adequate sample sizes and correction for perplexing factors are needed since this could be an innovative treatment in atopic children. It is also advisable to examine high-risk groups of children for vitamin D deficiency.
According to the extracted data, vitamin D has a protecting effect against atopic diseases. At the same time, no evidence was found for such an association in some studies, thus, further studies are needed to clarify this issue.- انتشار مقاله: 17-03-1397

- چکیده انگلیسی: The active form of vitamin D is synthesized in some body organs following sun exposure and dietary intake. Vitamin D exhibits its major and critical effects not only through regulation of calcium and phosphate metabolism but also by influencing on respiratory and immune system. Serum concentrations of 25-hydroxyvitamin D below the optimum limit lead to vitamin D insufficiency or maybe deficiency. These inappropriate concentrations of vitamin D lead to different types of pulmonary diseases such as viral and bacterial respiratory infection, asthma, chronic obstructive pulmonary disease, and cancer. In this review we described the association between vitamin D deficiency and severe therapy resistant asthma. We also reviewed the underlying molecular mechanism of vitamin D deficiency in children with severe- therapy resistant asthma. Based on current information, future clinical trial are needed to study the role of vitamin D supplementation on different groups of patients with severe asthma including infants, children of school age, and ethnic minorities.

- چکیده انگلیسی: Background
The popularity of probiotics is on the rise. Despite the beneficial effects of antibiotics, gastrointestinal health is at risk of diarrhea. This study aimed to investigate whether probiotic yogurt is of capability to prevent the incidence of diarrhea versus conventional yogurt.
Materials and Methods
This controlled, randomized, double-blind trial was designed to recruit 48 hospitalized children, whose treatments included different types of antibiotics. They were subsequently assigned into a 1:1 ratio into groups A and B at random. The first group was instructed to consume probiotic yogurt (Bifidobacterium strains and Lactobacillus acidophilus), while the second were on conventional yogurt (placebo containing Streptococcus thermophiles and Lactobacillus bulgaricus) at least for 7 days. The incidence of diarrhea, its onset and duration were compared between the two groups.
Results
The findings indicated that there was no statistically significant difference between the experimental and control groups (p > 0.05). No significant decrease was observed in the incidence of diarrhea between the groups following adjustment for negative C-reactive protein (CRP) (p > 0.05).
Conclusion
According to the results, the consumption of yogurt, either probiotic or conventional, reduced the incidence, duration, and onset of antibiotic-associated diarrhea in pediatric population. This study showed no significantly better performance for probiotic yogurt than conventional yogurt.- انتشار مقاله: 25-07-1396

- چکیده:
- چکیده انگلیسی: Introduction
Mild intermittent asthma is common in children and viral infections are responsible for the majority of exacerbations. As leukotrienes are potent inflammatory mediators, some studies have shown that Montelukast, a leukotriene receptor antagonist, may be effective on reduction of asthma symptom. To determine whether a short course of Montelukast in asthmatic children with common cold would modify the severity of an asthma episode.
Materials and Methods
Children, aged 6-12 years with intermittent asthma participated in this randomized, double-blind, placebo-controlled clinical trial. Treatment with Montelukast or placebo was initiated at the onset of viral upper respiratory tract infection and continued for 7 days. Primary outcomes included the clinical manifestation: duration of episodes, daily symptom, nights symptoms and activity limitation. Secondary outcomes included the need for beta agonist usage, oral prednisolone, physician visit, hospital admission and school absence.
Results
A total of 187 children with intermittent asthma were randomized, 93 to Montelukast group and 94 to placebo group. Montelukast significantly decreased the cough by 17.3% (P<0.001), nighttime awakenings by 5.4% (P=0.01), interference with normal activity by 6% (P<0.01), time off from school by 6% (P<0.01), β-agonist usage by 17.2% (P<0.001) and doctor visits by12.2% (P<0.01) compared to placebo. Whereas there was a non significant reduction in wheezing, tachypnea, respiratory distress, asthma exacerbation, oral prednisolone and hospitalization (P=0.8).
Conclusion
A short course of Montelukast, introduced at the first sign of a viral infection, results in a reduction in cough, β-agonist use and nights awakened, time off from school and limitation of activity. More studies are needed to evaluate the optimal dose and duration of treatment.- انتشار مقاله: 25-03-1392

- چکیده:
- چکیده انگلیسی: Primary immunodeficiency (PID) is a group of more than 400 distinct genetic disorders affecting both children and adults. As signs and symptoms of PID are usually heterogeneous and unspecific, based on the available human resources and laboratory facilities, diagnosis and follow-up of these patients can be challenging. In line with this notion, management and treatment of PID are practiced divergently in different PID centers. In order to reach a distinct national protocol and given the little evidence on appropriate or universal guidelines to improve the current status of management of the disease, the Iranian PID network designed a consensus suitable for regional resources. This review summarizes this PID guideline based on the importance of different clinical complications and the level of medical authority visiting those at the first line. Further, for each complication, appropriate interventions are mentioned to improve the approach.
