A case of celiac disease

Celiac disease is a chronic autoimmune disorder triggered by the consumption of gluten, a protein found in wheat, barley, and rye. In individuals with celiac disease, gluten consumption leads to an immune response that damages the lining of the small intestine, resulting in various symptoms and potential long-term complications. Here’s a typical case of celiac disease:

Patient Profile:

  • Age and Gender: A 32-year-old female
  • Medical History: No significant medical history; may have experienced gastrointestinal symptoms like bloating, abdominal pain, and irregular bowel movements in the past.

Presenting Symptoms:

  • Digestive Symptoms: Chronic diarrhea or constipation, bloating, abdominal pain, gas, nausea, and vomiting.
  • Fatigue: Unexplained fatigue and weakness.
  • Weight Loss: Unintentional weight loss or difficulty gaining weight.
  • Nutrient Deficiencies: Deficiencies in vitamins (e.g., B12, D, iron, folate) and minerals (e.g., calcium) due to poor nutrient absorption in the intestine.

Clinical Evaluation and Diagnosis:

  1. Medical History and Physical Examination: The patient’s medical history and symptoms suggest a gastrointestinal disorder. Physical examination may reveal signs of malnutrition or nutrient deficiencies.
  2. Blood Tests:
  • Antibody Testing: Serological tests to detect specific antibodies (e.g., anti-tissue transglutaminase antibodies, anti-endomysial antibodies) associated with celiac disease.
  • Complete Blood Count (CBC): To check for anemia, a common finding in celiac disease.
  1. Intestinal Biopsy:
  • Upper Endoscopy with Biopsy: If blood tests suggest celiac disease, an upper endoscopy is performed to obtain small intestine tissue samples (biopsy) to confirm the diagnosis. The characteristic histological changes associated with celiac disease include villous atrophy, increased intraepithelial lymphocytes, and crypt hyperplasia.
  1. Genetic Testing:
  • HLA Typing: Genetic testing to identify HLA-DQ2 and HLA-DQ8 genotypes, which are associated with an increased risk of celiac disease. However, having these genotypes does not guarantee the development of the disease.

Diagnosis: Based on positive serological tests, characteristic histological changes on biopsy, and potential HLA-DQ2 or HLA-DQ8 genotypes, a diagnosis of celiac disease is confirmed.

Management and Treatment:

  • Gluten-Free Diet: Strict adherence to a lifelong gluten-free diet, avoiding all sources of gluten, including wheat, barley, and rye.
  • Dietary Counseling: Consultation with a registered dietitian to learn about gluten-free alternatives and proper nutrition.
  • Follow-up Monitoring: Regular follow-ups with healthcare providers to monitor symptoms, nutritional status, and antibody levels. Additional biopsies may be performed to assess intestinal healing over time.

Celiac disease is a chronic condition that requires lifelong dietary management and monitoring to prevent symptoms and complications associated with gluten ingestion.
