Insights

Severe atopic dermatitis (AD) can cause protein-losing enteropathy (PLE). This case highlights the importance of considering PLE in infants with severe AD and low protein levels, even after eczema treatment.

Area of Science:

  • Pediatric Dermatology
  • Gastroenterology
  • Clinical Case Study

Background:

  • Severe atopic dermatitis (AD) is a chronic inflammatory skin condition.
  • Hypoproteinaemia is a potential complication of severe AD.
  • Protein-losing enteropathy (PLE) is characterized by excessive protein loss through the gastrointestinal tract.

Observation:

  • A 7-month-old infant with severe AD, untreated with topical corticosteroids due to familial steroid phobia.
  • Infant presented with decreased feeding, diarrhea, reduced urine output, and vomiting.
  • Despite initial improvement of eczema with topical corticosteroids, persistent hypoproteinaemia, oliguria, and worsening edema were noted.

Findings:

  • Serum albumin scintigraphy confirmed protein-losing enteropathy (PLE) in the distal duodenum.
  • Treatment with systemic prednisolone and albumin resolved PLE symptoms and prevented relapse.
  • This case represents one of the few reported instances of PLE associated with AD in infancy.

Implications:

  • PLE should be considered in the differential diagnosis of infants presenting with severe atopic dermatitis and persistent hypoproteinaemia.
  • Early recognition and management of PLE are crucial in pediatric patients with severe AD.
  • This case underscores the complex interplay between severe skin inflammation and gastrointestinal dysfunction in infants.

Overview of Protein Metabolism

Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
