Insights

This case report details a patient with coeliac disease (CD) and an unusual co-occurrence of primary immunodeficiency (PID), specifically natural killer cell deficiency. The complex presentation underscores the need to investigate PID in autoimmune cases.

Area of Science:

  • Immunology
  • Gastroenterology
  • Clinical Medicine

Background:

  • Coeliac disease (CD) is an autoimmune disorder often associated with other immune conditions.
  • Primary immunodeficiency diseases (PID) can present with recurrent infections and autoimmunity.
  • The coexistence of CD and PID presents diagnostic and management challenges.

Observation:

  • A patient initially diagnosed with CD showed a poor response to standard treatment.
  • Recurrent opportunistic infections prompted an investigation into immunodeficiency.
  • The patient exhibited natural killer (NK) cell deficiency and low immunoglobulin levels (IgA, IgG2).

Findings:

  • The case highlights an unusual presentation of CD coexisting with PID.
  • Natural killer cell deficiency was identified as a key factor in the patient's susceptibility to infections.
  • Low serum IgA and IgG2 levels were noted alongside the NK cell deficiency.

Implications:

  • This case emphasizes the importance of considering PID in patients with refractory CD or recurrent infections.
  • Early investigation of PID in autoimmune patients can lead to timely diagnosis and management.
  • Understanding the interplay between CD and PID is crucial for improving patient outcomes.
