CD55 deficiency with hyperactivation of complement, angiopathic thrombosis, and protein-losing enteropathy (the CHAPLE syndrome) is caused by abnormal complement activation due to biallelic loss-of-function mutations in CD55.

PurposeCalprotectin is a cytosolic protein with immunomodulatory, antimicrobial, and antiproliferative actions. The concentration of calprotectin increases in infection, inflammation, and malignancy. We determined if calprotectin can be used as a marker for the diagnosis and follow-up of bowel inflammation in cow's milk protein allergy (CMPA).MethodsIn total, 32 patients newly diagnosed with CMPA were included (24 IgE-mediated, 8 non-IgE-mediated). In all subjects, a complete blood count, total IgE, cow's milk-specific IgE, and fecal calprotectin (FC) were assessed before and after a cow's milk protein (CMP) elimination diet was started. The results were compared with those of 39 healthy children.ResultsThe mean FC value before the CMP elimination diet was 516±311 µg/g in the 32 patients with CMPA and 296±94 µg/g in the control group (P=0.011). The mean FC value after the diet in these patients was 254±169 µg/g, which was significantly different from the mean value before the CMP elimination diet (P<0.001). When we compared FC levels before the CMP elimination diet in the IgE-mediated group with the control group, we found no significant statistical difference (P=0.142). The mean FC value before the CMP elimination diet was 886±278 µg/g in the non-IgE-mediated group and 296±94 µg/g in the control group; this difference was statistically significant (P<0.001). In the IgE-mediated and non-IgE-mediated groups, FC values after CMP elimination diet were 218±90 µg/g and 359±288 µg/g, respectively, and FC values before CMP elimination diet were 392±209 µg/g and 886±278 µg/g, respectively; these differences were statistically significant (P=0.001 and P=0.025, respectively).ConclusionsFC levels may be a useful marker for follow-up treatment and recurrence determination in CMPA.
Use of anthropometric measurements in addition to screening tools to identify hospital malnutrition (such as PYMS, STRONGkids) will prevent some nutritional risk patients from being overlooked.
Although liver fibrosis can be detected using SWE, differentiation of fibrosis stages could not be achieved. The presence of steatosis significantly increased the mean SWE values on elastography and so care should be taken when assessing children with nonalcoholic steatohepatitis.
In spite of the small number of patients with mutations affecting the IL-10 signaling pathway in our study, in all of the patients with IL10 receptor mutations, the disease onset occurs at an early age, the prognosis is poor, and the response to treatment is insufficient.
Background/AimsIrritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders and when compared to the vast knowledge pertaining to adults with IBS, very little is known about IBS in children and adolescents. We aimed to explore the prevalence of IBS, identify symptoms and contributing factors and also to examine the efficacy of trimebutine maleate in children and adolescents.MethodsThe study involved 345 children and adolescents (4-18 years) and parents were requested to fill in a questionnaire, Rome III criteria was used to diagnose IBS. To exclude organic disease, all patients underwent medical investigations. Half of the randomly selected IBS patients were treated with trimebutine maleate while the rest of IBS patients were not. The IBS patients were reevaluated at the end of 3 weeks.ResultsThe prevalence of IBS according to Rome III criteria in children and adolescents was 22.6% and IBS with constipation was the predominant subtype. Back pain (OR, 6.68), headache (OR, 4.72) and chronic fatigue (OR, 3.74) were significantly higher in IBS group. The prevalence of IBS in both parents and depression in mothers was greater for the patient group than the healthy controls (P < 0.0001). The prevalence of functional dyspepsia in IBS group was 80.8% and was significantly higher than control group. Clinical recovery was seen in 94.9% of the trimebutine maleate group versus spontaneous recovery in 20.5% of the non-medicated group. The difference was significant (P < 0.0001).ConclusionsIBS is a common disorder in children and adolescents. IBS is closely associated with somatic and familial factors. Trimebutine maleate is effective for pediatric IBS patients.
We found that the number of patients with FMF was higher than the number with IBD in the general population. When IBD accompanied FMF, the most common mutation was M694 V; however, the high rate (25%) of K695R mutation in our patients with FMF and IBD was not observed in previous studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
