Malabsorption children

BACKGROUND: Micronutrient deficiencies from malabsorption, gut infections, and altered gut barrier function are common in children living with the human immunodeficiency virus (CLHIV) and may worsen with severe acute malnutrition (SAM). Exploratory data of baseline zinc and selenium levels and changes over 48 weeks in children living with HIV by nutritional status are presented. METHODS: Zinc, selenium, serum protein and albumin levels measured at study entry and over 48 weeks were compared between children aged 6 to < 36 months who were living with HIV and had SAM or mild malnutrition-normal nutrition...

OBJECTIVE: The aim of this study is to determine the prevalence of acute malnutrition and associated factors in South Wollo zone, East Amhara, Northeast Ethiopia. DESIGN: A community-based cross-sectional study was conducted among 504 children aged 6-59 months who were selected by using a multistage sampling technique. The mid-upper-arm-circumference and Z-scores for weight-for-height were used to determine the nutritional status of the participants. A semi-structured interview questionnaire was used to collect the data...

Norovirus infection in children on treatment for acute lymphoblastic leukemia can lead to severe morbidity due to chronic viral shedding, malabsorption, failure to thrive, and interruption of chemotherapy. We had four children with norovirus diarrhoea in eight years period in our pediatric oncology unit. Three children under two years of age had chronic noroviral shedding and persistent diarrhoea, probably due to poor adaptive immune responses. Two of those children didn't respond to nitazoxanide and succumbed to the illness...

UNLABELLED: The assessment of the nutritional and inflammatory status of paediatric patients with coeliac disease is an interesting approach to early diagnosis and functional follow-up. Most authors agree that the normalisation of symptoms takes about one year. The aim of the study was to evaluate the clinical manifestation and normalisation of routine analytics in Spanish children diagnosed with celiac disease. METHODS: We performed a retrospective case-control study in Spanish paediatric patients, including 21 celiac patients and 20 healthy controls...

Functional abdominal pain disorders (FAPDs) are among the most common types of chronic pain disorders in children. FAPD symptoms are characterized by chronic abdominal pain and changed bowel movements. The pathophysiology of FAPDs in children is unknown, but these conditions may have an imprecise clinical overlap to food intolerance/malabsorption. We report on 51 consecutive children (23/28 males/females; median age 15.3 years) with investigated FAPDs from 2017 to 2022 in this retrospective pilot study. Small intestinal biopsies in children demonstrated the association of lactase and diamine oxidase (DAO), which prompted us to perform hydrogen (H2 ) breath tests for lactose intolerance (LIT) and determine serum DAO for the evaluation of histamine intolerance (HIT) in pediatric patients with FAPDs...

BACKGROUND: The intestine of children with severe malnutrition (SM) shows structural and functional changes that are linked to increased infection and mortality. SM dysregulates the tryptophan-kynurenine pathway, which may impact processes such as SIRT1- and mTORC1-mediated autophagy and mitochondrial homeostasis. Using a mouse and organoid model of SM, we studied the repercussions of these dysregulations on malnutrition enteropathy and the protective capacity of maintaining autophagy activity and mitochondrial health...

BACKGROUND: Cryptosporidium is one of the major pathogens causing diarrhea worldwide. At present, cryptosporidiosis is difficult to prevent and control, especially in immunocompromised hosts. It may cause life-threatening diarrhea and malabsorption among children and immunocompromised patients. Therefore, it is very important to explore rapid diagnostic tools and treatment methods for Cryptosporidium infection. CASE PRESENTATION: We reported a case of severe diarrhea caused by cryptosporidiosis in a liver transplant recipient, whose condition was finally confirmed by metagenomic next-generation sequencing (mNGS) and fecal microscopy...

Unintentional weight loss is common in persons with chronic and acute disease and is often caused by insufficient intake or malabsorption. A new lysophosphatidylcholine (LPC)-rich structured lipid powder has micelle-like activity that facilitates digestion and absorption, independent of lipase and bile acids. The aim of this secondary analysis was to determine if recycled LPC increased fat absorption of coingested food. Fasting plasma fatty acid (FA) concentrations were measured at baseline and 3 mo in children ( n = 84) with cystic fibrosis and pancreatic insufficiency...

Small intestinal bacterial overgrowth (SIBO) is defined as the presence of an excessive number of bacteria within the small bowel. Pediatric SIBO is a heterogeneous disorder that manifests as various symptoms ranging from mild gastrointestinal symptoms to malabsorption or malnutrition. The carbohydrate breath test is a commonly used, safe, and noninvasive diagnostic test; however, a standardized methodology is lacking. Multiple factors, such as neuromuscular disorders, systemic diseases, chronic drug use, or altered intestinal anatomy that disturb intestinal motility or induce an abnormality in the body's defense systems against intestinal bacteria, predispose children to SIBO...

This review summarizes findings from studies assessing the nutritional status of patients with celiac disease (CD). Malnutrition, including over- and undernutrition, may be present in CD, both at diagnosis and while under treatment. Underweight and growth retardation in children, which mostly reflect malabsorption as a consequence of intestinal inflammation, are not a rule. Clinical presentations of CD can vary widely, and each manifestation has its own characteristics. Evaluating various nutritional parameters can be beneficial for CD patients and may improve health outcomes by facilitating an accurate definition of dietary needs and the development of a balanced diet that not only focuses on eliminating gluten but also provides adequate nutrients, alters metabolism, and reduces the risk of other disorders developing...

Celiac disease is an autoimmune disorder in which the immune system of genetically susceptible individuals elicits a reaction to gluten causing small intestine damage. If left undiagnosed and untreated, the resulting nutrition malabsorption can lead to anemia, bone disease, growth faltering, or other consequences. The condition is lifelong and lacks a cure; the only treatment is lifelong adherence to a gluten-free diet (GFD). This diet is challenging to follow and adversely influences quality of life; however, it is essential to ensure intestinal recovery and prevent future negative health consequences...

BACKGROUND: Worldwide, iron deficiency anemia is the most prevalent nutritional deficiency disorder and the leading cause of anemia in children, especially in developing countries. When present in early childhood, especially if severe and prolonged, iron deficiency anemia can result in neurodevelopmental and cognitive deficits, which may not always be fully reversible even following the correction of iron deficiency anemia. OBJECTIVE: This article aimed to familiarize physicians with the clinical manifestations, diagnosis, evaluation, prevention, and management of children with iron deficiency anemia...

Small bowel villous atrophy is most often caused by celiac disease in the Western world, but other diseases should be explored in patients without positive serology. Adult-onset autoimmune enteropathy (AIE) is a rare cause of villous atrophy first known in children with T-cell dysregulation but also seen in adults with autoimmune predispositions. Here, an 82-year-old woman with autoimmune thyroiditis was admitted with weight loss and watery diarrhoea not responding to diet change. Endoscopy revealed villous atrophy both in the duodenum and in the ileum, but no positive celiac serology...

OBJECTIVE: Nutritional status and growth is well associated with disease outcomes and lung function in patients with cystic fibrosis (CF). Current dietary guidelines for the management of CF suggest a high-calorie, high-fat diet. Pancreatic insufficiency (PI) is present in most patients and contributes to malabsorption and malnutrition, but a considerable number of patients have pancreatic sufficiency (PS). The aim of this study was to compare weight status, clinical characteristics, and dietary intake of children with CF, with PS or PI...

Celiac disease (CD) and systemic lupus erythematosus (SLE) are two diseases intensively studied in all age groups, with an increasing incidence at the global level, possibly due to the increased awareness of the diseases and their accurate diagnosis and as a consequence of the new research and innovation technologies that have appeared in medicine. The first is a controllable condition found in approximately 1% of the entire population in the form of a reaction to environmental stimuli affecting individuals with genetic susceptibility, causing gluten intolerance, gastrointestinal and extradigestive symptoms, starting from subclinical stages and culminating in severe malabsorption...

BACKGROUND: This review aims to identify the current indications and gaps in the management of fat-soluble vitamins in pediatric patients with cholestasis. METHODS: A comprehensive review of the literature using PubMed, Scopus, Web of Science and Embase was performed. Two authors independently identified the most relevant studies published over the past 20 years up to February 2022, including original papers, narrative reviews, observational studies, clinical trials, systematic reviews and meta-analyses...

BACKGROUND: Suboptimal vitamin D status is common in people with celiac disease (CeD), a disease that can be characterized by the presence of serum anti-tissue transglutaminase antibodies (TG2A) (i.e., TG2A positivity). To date, it remains unclear whether childhood TG2A positivity is associated with vitamin D status and how this potential association can be explained by other factors than malabsorption only, since vitamin D is mainly derived from exposure to sunlight. The aim of our study was therefore to assess whether childhood TG2A positivity is associated with vitamin D concentrations, and if so, to what extent this association can be explained by sociodemographic and lifestyle factors...

Biliary atresia (BA) is a rare congenital liver disease with unknown etiology, and it is the most common indication for liver transplantation in children. As BA infants suffer from intestinal malabsorption and neurodevelopmental deficits, it is necessary to identify optimal medical and nutritional strategies using appropriate neonatal animal models. We aim to determine the feasibility of using newborn piglets with surgically induced cholestasis (bile duct ligation (BDL)) to mimic clinical features of BA. Six piglets were subjected to abdominal surgery on day 4 after birth...

BACKGROUND: Celiac disease (CD) is associated with malabsorption and consequential nutritional deficiencies. Patients with CD must follow a gluten-free diet (GFD), which is also associated with nutrient deficiencies. Despite the clinical significance, consensus is lacking on the pattern and frequency of nutrient deficiencies in CD and the usefulness of assessment during follow-up. The aim was to investigate the presence of micronutrient and protein deficiencies in pediatric patients with CD after starting a GFD and receiving standard clinical care, taking disease activity into account...

Short-bowel syndrome (SBS) in pediatric age is defined as a malabsorptive state, resulting from congenital malformations, significant small intestine surgical resection or disease-associated loss of absorption. SBS is the leading cause of intestinal failure in children and the underlying cause in 50% of patients on home parental nutrition. It is a life-altering and life-threatening disease due to the inability of the residual intestinal function to maintain nutritional homeostasis of protein, fluid, electrolyte or micronutrient without parenteral or enteral supplementation...
