Management of the Most Common Functional Gastrointestinal Disorders in Infancy: The Middle East Expert Consensus.

The occurrence of functional gastrointestinal disorders (FGIDs) is a formidable challenge for infants, parents, and healthcare professionals. Although data from the Middle East are scarce, experts consider FGIDs a prevalent condition in everyday clinical practice. The new Rome IV criteria revisited the definitions from a clinical perspective to provide a practical and consistent diagnostic protocol for FGIDs. However, the treatment practices for functional disorders vary considerably among Middle Eastern countries, often resulting in mismanagement with unnecessary investigations and treatments. In addition, the role of various treatment modalities, including probiotics such as Lactobacillus reuteri DSM 17938, in FGIDs requires further discussion and evaluation. During a consensus meeting, a locally relevant approach for treating common FGIDs such as infant regurgitation, infant colic, and functional constipation was discussed and approved by regional experts. The participants suggested a simplified treatment plan and protocol for general pediatricians and other primary care physicians managing FGIDs. This easy-to-follow standardized protocol will help streamline the initial management of this complex disorder in the Middle East region and even globally.

Incidental finding of a needle in the root of the mesentery of an 11-month-old boy: A case report.

Foreign body (FB) ingestion is very common in the pediatric population. Children will have different presentations based on their age, size, type, and site of the ingested FB. Some children can present with serious complications, others can be completely asymptomatic. An eleven-month-old male child, previously healthy, was following up with the family medicine department for a routine visit. A pelvic x-ray was done to rule out developmental dysplasia of the hip, and a needle was found incidentally in the small bowel loops. The child was completely asymptomatic. Daily radiographs were taken three days in a row and showed that the needle was still in place. The patient was then referred to the pediatric surgery department for laparoscopic exploration and removal of the needle before complications occur. During exploration, the needle was found at the root of the mesentery. The needle was taken out uneventfully without the evidence of perforation. It is unusual to find a sharp FB located at the root of the mesentery in a completely asymptomatic infant as an incidental finding. Serial radiographic images after the initial presentation of foreign body ingestion is important to guide us through surgical intervention.

PLACK syndrome is potentially treatable with intralipids.

We describe an 11-year-old girl with PLACK Syndrome (peeling skin, leukonychia, acral punctate keratosis, cheilitis, and knuckle pads), who was found to have a novel homozygous variant in CAST, the pathogenicity of which was confirmed using blood-derived RNA. There is no established treatment for PLACK syndrome. However, we demonstrate for the first time that this condition is associated with low levels of vitamin A and essential fatty acids, which prompted us to consider a potential treatment strategy. Indeed, we initiated this patient on intravenous lipid infusion (Vitalipid®; an emulsion of fat-soluble vitamins and lipofundin-MCT/LCT 20%) and the response was dramatic. Following the fourth monthly course of treatment, pruritis disappeared and the skin lesions showed remarkable objective improvement. PLACK syndrome is a very rare genodermatosis and only six families have been described to date with pathogenic CAST variants. This is the first report of an objective response to a therapeutic agent, which suggests that PLACK is a potentially treatable condition. The remarkable response we report and the relative safety of the intervention should prompt healthcare providers who care for PLACK syndrome patients to explore this as a potential treatment strategy in future studies.

SLC5A1 Mutations in Saudi Arabian Patients With Congenital Glucose-Galactose Malabsorption.

Congenital glucose-galactose malabsorption (cGGM) is a rare autosomal recessive disorder, caused by mutations in the SLC5A1 gene, encoding the sodium/glucose cotransporter 1, which may result in severe life-threatening osmotic diarrhea due to the accumulation of unabsorbed sugars in the intestinal lumen. If treated early with elimination of glucose and galactose from the diet, patients usually recover and develop normally. We present clinical and molecular data from 16 unrelated cGGM diagnosed Saudi patients from consanguineous families with majority of them having previous positive family history of cGGM. Sanger sequencing for the full coding regions of SLC5A1 for all patients resulted in the identification of 4 allelic variants in a homozygous state. Two mutations are novel; c.265G>A (p.G89R) and c.1304 G>A (p.G435D), and 2 have been previously reported to cause cGGM, c.765 C>G (p.C255W) and c.1136 G>A (p.R379Q). This is the first report delineating the clinical and molecular basis of cGGM in patients from this region.

Prevalence of celiac disease in Saudi children with Down syndrome: A retrospective study.

Celiac disease (CD) is an immune-mediated disease affecting the small intestine secondary to gluten exposure. The currently available treatment is lifelong adherence to a gluten-free diet (GFD). Several disorders are known to be associated with celiac disease, including Down syndrome (DS). In several studies, the prevalence of CD in DS ranged between 4 and 17%. CD is prevalent in Arabs; however, few studies have been performed to determine the prevalence of CD in DS patients. Our study aimed to determine the prevalence of CD in Saudi Down syndrome patients using serological markers and small bowel biopsy. This is a retrospective study in which files relating to Down syndrome patients who were followed up in a general pediatric clinic at King Faisal Specialist Hospital and Research Center were reviewed regarding demographic data, serological markers and biopsy results. Of the total number of patients reviewed (91), 7 were excluded because data were missing; the remaining 84 patients included 35 females and 49 males. The age range of the patients at the time of screening was from 1 to 18 years. Patient demographic data are shown in Table 1. Among the studied patients, antigliadin antibody (AGA) IgA was high in 27 patients (32.14%), and AGA IgG was high in 44 patients (52.38%). Twelve patients (14.28%) tested positive and 58 (69.04%) tested negative for anti-endomysial antibodies. Anti-tissue glutaminase antibody IgA was found to be high in 13 patients (15.5%) and normal in 54 patients (64.28%). Serum IgA levels were normal in 36 patients (43%) and low in 1 patient (1.2%). Biopsy was performed in 22 patients who tested positive for anti-endomysial or anti-tissue transglutaminase antibodies. The biopsies provided positive results in 9 patients (10.7%). Our study showed a confirmed prevalence of 10.7% for celiac disease in Saudi patients with Down syndrome based on serology and biopsy; together with previous cases reported in the literature, this result indicates a need to screen these patients for celiac disease.

Intestinal lymphangiectasia in a patient with infantile systemic hyalinosis syndrome: a rare cause of protein-losing enteropathy.

Infantile systemic hyalinosis (ISH) is a rare autosomal recessive disease. Typically, ISH patients present with progressive painful joint contractures, intractable diarrhea, hyperpigmented skin lesions, and peri-anal fleshy nodules. We report a case of a 19-month-old male child with atypical ISH presentation. His main clinical finding was protein-losing enteropathy due to intestinal lymphangectasia. This report is intended to enhance awareness about the gastrointestinal tract presentation of ISH.
