Congenital Diarrhea 5 with Tufting Enteropathy: A Rare Inherited Condition

Congenital diarrhea 5 with tufting enteropathy is a rare inherited condition characterized by severe and intractable diarrhea in infancy. This condition is also known as Congenital Tufting Enteropathy (CTE).

Key Features:

• Severe Diarrhea: The primary symptom of CTE is severe and persistent diarrhea, which can lead to dehydration and electrolyte imbalances.
• Villous Atrophy: The intestinal lining undergoes villous atrophy, leading to a reduction in the surface area for nutrient absorption.
• Absence of Inflammation: Unlike other forms of diarrhea, CTE is characterized by the absence of inflammation in the intestines.
• Intestinal Epithelial Cell Dysplasia: Focal epithelial tufts are present in the duodenum and

Early Signs and Symptoms

Congenital tufting enteropathy (CTE) typically presents within the first few months of life, with symptoms appearing as early as hours or days after birth. The primary sign is severe, watery diarrhea that does not resolve on its own [10]. This condition leads to malabsorption of nutrients from food, causing failure to thrive and significant morbidity.

Common Symptoms

• Severe, watery diarrhea
• Failure to thrive (weight loss and growth retardation)
• Vomiting and abdominal distension in some cases [9]
• Elevated osmolality, osmotic gap, and stool volume may be observed [9]

Clinical Features

The symptoms of CTE are often accompanied by villous atrophy and absence of inflammation in the small intestine. Intestinal epithelial cell dysplasia manifests as focal epithelial tufts in the duodenum and jejunum [1]. These features can lead to irreversible intestinal failure if left untreated.

Associated Conditions

CTE is an inherited disorder that affects the small intestine, leading to severe diarrhea and malabsorption of nutrients. It is essential to diagnose this condition early on to prevent long-term complications and ensure proper management.

CTE presents in the first few months of life with chronic watery diarrhea and failure to thrive, and most affected individuals require parenteral nutrition for survival. [9] Apart from intractable diarrhea, some CTE patients develop vomiting and abdominal distension [12,21]. Elevated osmolality, osmotic gap and stool volume may be observed [9]. [10] Signs of tufting enteropathy usually present within hours or days after birth. However, sometimes the symptoms appear later (around two months after birth) and are less severe. When babies have severe, watery diarrhea that doesn't go away, they cannot absorb the nutrients that they eat. [12] 1 Signs and symptoms.

Diagnostic Tests for Congenital Diarrhea 5 with Tufting Enteropathy

Congenital diarrhea 5 with tufting enteropathy, also known as congenital tufting enteropathy (CTE), is a rare inherited intractable diarrhea of infancy characterized by villous atrophy and absence of inflammation. Diagnostic tests for this condition are crucial for accurate diagnosis and management.

• Molecular Genetics Tests: These tests can help identify the genetic mutations responsible for CTE. Targeted variant analysis, RNA analysis, sequence analysis of the entire coding region, and deletion/duplication analysis are some of the molecular genetics tests that may be used to diagnose CTE [1][4].
• Histological Examination: A histological examination of the duodenal biopsy can help determine the diagnosis of CTE. The characteristic epithelial tufting in the duodenum is a key feature of this condition [7].

Genetic Sequencing for Congenital Diarrhea and Enteropathy (CODE): Genetic sequencing has important implications for the diagnosis, prognosis, and implementation of treatment plans for children with congenital diarrhea and enteropathy, including CTE [8].

It's worth noting that a patient was diagnosed with autoimmune enteropathy (AIE) based on histopathological examination and anti-enterocyte IgA positivity, which may be a differential diagnosis to consider in cases of congenital diarrhea [9].

Current Drug Treatment Options for Congenital Diarrhea 5 with Tufting Enteropathy

Unfortunately, there are no direct therapeutics being used to treat or ameliorate Congenital Tufting Enteropathy (CTE) or its symptoms [3]. However, some treatments have been explored and reported in medical literature.

• GLP-2 agonist: Teduglutide has been used in other forms of intestinal failure, but there is no direct evidence of its effectiveness in treating CTE [3].
• Supportive treatment: Nutritional management through specialized formulas or total parenteral nutrition (TPN) therapy may be necessary to manage the condition [8]. In some cases, oral rehydration therapy has been used to treat associated diarrhea [6].

It's essential to note that definitive treatment for CTE is rarely available, and supportive treatment is often the mainstay of care [8]. Further research is needed to explore effective drug treatments for this rare congenital enteropathy.

Congenital Diarrhea with Tufting Enteropathy: Differential Diagnosis

Tufting enteropathy, also known as intestinal epithelial dysplasia, is a rare autosomal recessive disease of infancy that presents with profuse watery diarrhea. The differential diagnosis for congenital diarrhea with tufting enteropathy includes several conditions that can cause severe intestinal failure and electrolyte imbalances.

Conditions to Consider:

• Congenital chloride diarrhea: This condition is characterized by the inability to absorb chloride ions, leading to excessive loss of water and electrolytes in the stool.
• Congenital sodium diarrhea: Similar to congenital chloride diarrhea, this condition involves an inability to absorb sodium ions, resulting in severe electrolyte imbalances.
• Familial microvillous atrophy: This rare genetic disorder affects the small intestine's ability to absorb nutrients and can lead to severe malabsorption and diarrhea.
• Glucose-galactose malabsorption: A rare congenital disorder that impairs the absorption of glucose, galactose, and other sugars in the small intestine.

Key Features:

• Severe intestinal failure with electrolyte imbalances
• Profuse watery diarrhea
• Autosomal recessive inheritance pattern
