Endoscopy and allergy cow milk protein

The etiology of upper gastrointestinal bleeding (UGIB) varies by age, from newborns to adolescents, with some of the causes overlapping between age groups. While particular causes such as vitamin K deficiency and cow's milk protein allergy are limited to specific age groups, occurring only in neonates and infants, others such as erosive esophagitis and gastritis may be identified at all ages. Furthermore, the incidence of UGIB is variable throughout the world and in different hospital settings. In North America and Europe, most UGIBs are non-variceal, associated with erosive esophagitis, gastritis, and gastric and duodenal ulcers...

OBJECTIVES: The objective of this study is to determine demographic and clinical characteristics of infants and toddlers <2 years with eosinophilic esophagitis (EoE) and to assess treatment response in this rarely studied pediatric age group. METHODS: Retrospective study of children <2 years diagnosed with EoE at a single center from 2016 to 2018. EoE was defined by ≥15 eosinophils per high power field (eos/hpf) on at least 1 esophageal biopsy. Demographics, symptoms, and endoscopic findings were collected via chart review...

PHYSIOLOGICAL OR PATHOLOGICAL ? Gastroesophageal reflux (GER) is defined by the rise of gastric contents into the esophagus, with or without externalization. GER is very common in young infants, with a peak around 4 months, and most often physiological due to high milk intakes and inappropriate relaxation of the lower esophageal sphincter. Evoking a GER disease (GERD) is not always obvious due to signs of poor specificity (crying, irritability, regurgitation). On the other hand, one should not miss warning signs evocative of GERD complicated by esophagitis or of recurrent upper respiratory or ENT infections, or even differential diagnoses (cow milk protein allergy, eosinophilic esophagitis, congenital malformations or brain tumours, etc...

Cow's milk allergy (CMA) and gastro-esophageal reflux disease (GERD) may manifest with similar symptoms in infants making the diagnosis challenging. While immediate reaction to cow's milk protein indicate CMA, regurgitation, vomiting, crying, fussiness, poor appetite, sleep disturbances have been reported in both CMA and GERD and in other conditions such as functional gastrointestinal disorders, eosinophilic esophagitis, anatomic abnormalities, metabolic and neurological diseases. Gastrointestinal manifestations of CMA are often non-IgE mediated and clinical response to cow's milk free diet is not a proof of immune system involvement...

Very-early-onset inflammatory bowel disease (VEO-IBD) has a distinct phenotype and should be considered a specific entity. VEO-IBD presents with very severe clinical pictures and is frequently known by an indeterminate colitis whose clinical remission is unmanageable. This study examines the case of a neonate with VEO-IBD, not responding to medical and surgical treatment. A 7-day-old Iranian female neonate presented with severe bloody diarrhea, poor feeding, abdominal distention, and dehydration suggesting severe proctocolitis due to an allergy to the protein in cow's milk...

RATIONALE: Celiac disease is a chronic, immune-mediated, multiorgan disorder that affects susceptible individuals, and it is triggered by gluten and other prolamins. PATIENT CONCERNS: We present the case of a 1-year-old male child, with a history of idiopathic pericardial effusion, admitted in our clinic for severe abdominal bloating, irritability, loss of appetite and intermittent diarrheic stools. The clinical findings were: influenced general status, irritability, distended abdomen, and diffuse abdominal tenderness...

BACKGROUND: The clinical presentation of cow's milk protein allergy (CMPA) in children varies. This retrospective study aimed to investigate the prevalence and clinical manifestations of CMPA in young children who visited for evaluation of iron deficiency anemia (IDA). METHODS: Patients aged <4 years who were diagnosed as having IDA (serum ferritin <12 ng/mL) at the National Cheng Kung University Hospital, Taiwan in the period 2005-2015 were reviewed. Their clinical presentations, laboratory data, endoscopy findings, and prognosis were analyzed...

The gastrointestinal form of food allergy is very common in children. The most frequently observed types are allergic proctitis and proctocolitis. In most cases the symptoms subside within the first 2 months of life. The babies seem healthy, and the only abnormality is a small amount of blood in stool. Symptoms can also include small intestine inflammation and colitis. Patients may present with irritability, abdominal pain, flatulence, colic, postprandial vomiting, chronic diarrhoea, and hindered physical development...

BACKGROUND: Cow's milk protein allergy is the most common cause of food allergy. The challenge test, either open or doubled-blind with a placebo control, is regarded as the criterion standard. Endoscopy and histologic findings are considered a method that can aid in the diagnosis of this entity. AIMS: The aim of this study was to describe the histopathologic findings in children suspected of cow's milk protein allergy that were seen at our hospital. MATERIAL AND METHODS: A descriptive, observational study was conducted on 116 children clinically suspected of presenting with cow's milk protein allergy that were seen at the Department of Gastroenterology and Nutrition of the Instituto Nacional de Pediatría...

Cow's milk protein allergy (CMPA) is common in infants with variable clinical presentation including varied gastrointestinal manifestation. Cow's milk protein allergy chiefly, involving occurs in children below the age of 3 years, successful therapy depends on completely eliminating cow's milk proteins (CMP) from the child's diet. Ideally, with the replacement of hypo or an allergenic food. Symptoms suggestive of CMPA may be encountered in approximately 5 to 15% of infants emphasizing the importance of controlled elimination/milk challenge procedures...

OBJECTIVE: there are many questions and little evidence regarding the diagnosis and treatment of gastroesophageal reflux disease (GERD) in children. The association between GERD and cow's milk protein allergy (CMPA), overuse of abdominal ultrasonography for the diagnosis of GERD, and excessive pharmacological treatment, especially proton-pump inhibitors (PPIs) are some aspects that need clarification. This review aimed to establish the current scientific evidence for the diagnosis and treatment of GERD in children...

Paediatric GERD is complicated to manage, as symptoms are diverse and often difficult to interpret. In infants, regurgitation is a common physiological condition. Nevertheless, when it occurs frequently (>4 times per day) and causes the infant distress, parents often seek medical help. In children 2-10 years of age, GERD is often considered to cause extra-oesophageal symptoms, despite the absence of hard evidence. Diagnostic investigations often lack solid validation and the signs and symptoms of GERD overlap with those of cow's milk protein allergy and eosinophillic oesophagitis...

Rectal bleeding in neonates is an alarming sign that suggests a possible serious underlying condition, such as infection or bleeding disorder that would necessitate hospitalization and prompt intervention. We report a case of eosinophilic gastroenteritis caused by cow's milk protein allergy in a one-day- old infant, who presented with frankly bloody stools associated with massive gastrointestinal and peripheral blood eosinophilia prior to initiation of enteral feedings. The patient's outcome was favorable, with complete spontaneous recovery in one week, after a period of bowel rest, parenteral nutrition, and use of amino acid formula...

GOAL: Milk-based formulas can induce cow’s milk protein allergy (CMPA) in infants. This article discusses two cases of severe CMPA in infants exposed to casein-based formulas. CASES: Case N°1: A 7 day old boy developed diarrhea with no improvement despite several courses of antibiotic and switching to formula without lactose. At 2 months of age he had a hemoglobin 8.6 mg/dL, IgE = 17.8 IU/ml (normal <1.5 UI/ml) and a CD4/CD8 ratio = 0.16 (normal 1.5 – 2...

BACKGROUND/AIMS: Infantile persistent diarrhea series are not well documented in the literature. Evaluating the literature, the aim of this study was to document persistent diarrhea cases followed in our center and to constitute a practical diagnostic algorithm for the pediatrician by means of surveying methods. METHODS: Diarrheas lasting more than 14 days were accepted as persistent diarrhea. Forty-one persistent diarrhea cases aged 0-24 months were investigated in this study...

BACKGROUND: Allergic proctocolitis (APC) in exclusively breast-fed infants is caused by food proteins, deriving from maternal diet, transferred through lactation. In most cases a maternal cow milk-free diet leads to a prompt resolution of rectal bleeding, while in some patients a multiple food allergy can occur. The aim of this study was to assess whether the atopy patch test (APT) could be helpful to identify this subgroup of patients requiring to discontinue breast-feeding due to polisensitization...

AIM: The aim of this prospective study was to determine cow's milk protein allergy (CMPA) cases in a tertiary care hospital in India and to study its clinical presentations and outcome following treatment. METHODS: Consecutive children with chronic diarrhea from June 2004 to December 2007 were evaluated with hemogram, anti-endomysial antibody, upper gastrointestinal endoscopy, sigmoidoscopy and intestinal biopsies. Initial diagnosis of CMPA was based on characteristic intestinal biopsy (> 6 eosinophils/HPF) and diagnosis was confirmed by positive milk challenge...

UNLABELLED: Patchy villous atrophy of duodenal mucosa has been described in young children with cow's milk allergy (CMA). Cow's milk protein-sensitive enteropathy may persist in older children and shows characteristic histological features. The advent of magnification endoscopy may allow the macroscopic detection of unrecognised villous atrophy in these patients. AIM: the aim of the study was to evaluate the duodenum mucosa in older children with CM A in infancy using chromoendoscopy and magnification endoscopy...

PURPOSE: The hypothesis put forward in the current study was that food intolerance can be a cause of gastroesophageal reflux (GER) affecting children with this pathology at various age. In order to confirm or exclude this hypothesis, the study objective was to determine the frequency of the cause-and-effect relationship between allergy to cow milk proteins and/or other food products and gastroesophageal reflux found in the study group of patients, and to establish diagnostic differentiation guidelines in GER caused by food intolerance, i...

UNLABELLED: Eosinophilic oesophagitis is an emerging disease, well known also in paediatric age, probably caused by both IgE and non-IgE mediated food allergies, diagnosed by upper endoscopy with biopsy. The most severe complication is oesophageal stenosis. The identification of the offending allergens is often difficult; therapy is focused to eliminate the supposed antigenic stimulus, to control the acute symptoms and to induce long-term remission. AIM: We report the clinical outcome and the typical endoscopic findings of children and adolescents affected by eosinophilic oesophagitis, referring a proposal of diagnostic and treatment protocol...
