Celiac disease (CD) is defined by gluten-induced immune-mediated enteropathy, affecting approximately 1% of the genetically predisposed population. The immunologic response to gluten causes characteristic intestinal alterations with gradual development. Histologic recovery of intestinal architecture was reported to occur within 6-12 months after starting a gluten-free diet, simultaneously with clinical remission. The aim of this study was to assess the rate and timing of histologic recovery among children with CD on a gluten-free diet, diagnosed and followed in an academic referral pediatric center during a 10-year period. ⋯ Histologic recovery in CD after starting a gluten-free diet in children takes at least 1 year and might be incomplete only in a small proportion of children, mainly associated with IgA immunodeficiency. Systematic follow-up of children with CD and persistent malabsorption syndrome is needed in order to avoid secondary complications.

Non-alcoholic fatty liver disease (NAFLD), considered the leading cause of chronic liver disease in children, can often progress from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH). It is clear that obesity is one of the main risk factors involved in NAFLD pathogenesis, even if specific mechanisms have yet to be elucidated. We investigated the distribution of intestinal bifidobacteria and lactobacilli in the stools of four groups of children: obese, obese with NAFL, obese with NASH, and healthy, age-matched controls (CTRLs). ⋯ Bifidobacteria seem to have a protective role against the development of NAFLD and obesity, highlighting their possible use in developing novel, targeted and effective probiotics.

Oxidative stress has been implicated in the normal ageing process and the pathogenesis of several diseases, including goitre. The aim of the study was to evaluate the relationship between urine lipid peroxidation (LPO) and anthropometric parameters as well as the parameters associated with goitre formation in children. ⋯ Anthropometric parameters of school-age children independently of age are negatively associated with oxidative damage to membrane lipids, whereas factors promoting goitrogenesis do not contribute to this process.

Apart from many positive changes associated with technical civilization, there are also - from the health point of view - some threats. The reduction in the level of physical activity is one of them. The aim of the study was to investigate whether there are any relationships between children's physical activity and behaviors, and to assess the impact of the adults' activity on their children's habits. ⋯ The level of physical activity in younger children depends on the children's relationship with their parents and their level of activity. Children spend a lot of free time with their electronic devices. It is necessary to develop and implement activities intended to raise awareness of children and their families about the effects of hypokinesis.

Elevated HbA2 (hemoglobin A2) level is considered the most reliable hematological parameter for the detection of β-thalassemia carriers. However, some carriers are difficult to recognize because the level of HbA2 is not in the distinctive carrier range, i.e. 4.0-6.0%; instead, some carriers have HbA2 levels between normal and carrier levels, i.e. borderline HbA2 (HbA2 = 3.1-3.9%). Studies have shown that variations in the erythroid Krüppel-like factor (KLF1) gene lead to borderline HbA2 in β-thalassemia carriers from various populations. The incidence of borderline HbA2 in Saudis is high. ⋯ Further studies are necessary to determine the influence of other factors on the presence of borderline HbA2 in 41.67% of Saudis.
