Unusual association of myasthenia gravis and ulcerative colitis in a 14-year-old boy

Area of Science:

• Gastroenterology and Immunology
• Pediatric Inflammatory Bowel Disease (IBD)
• Autoimmune Disorders

Background:

• Ulcerative colitis (UC) is a chronic inflammatory condition affecting the colon, with a notable incidence in the pediatric population.
• Extradigestive manifestations are common in inflammatory bowel disease (IBD), but neurologic complications are infrequently reported.
• Early diagnosis and management are crucial for improving long-term outcomes in pediatric IBD patients.

Observation:

• A 14-year-old boy was diagnosed with ulcerative colitis (UC).
• Subsequently, he developed autoimmune hepatitis with primary sclerosing cholangitis.
• Two months later, he was diagnosed with myasthenia gravis, a distinct autoimmune condition.

Findings:

• This case illustrates a rare clustering of multiple autoimmune diseases in a single pediatric patient with IBD.
• The patient presented with ulcerative colitis, autoimmune hepatitis, primary sclerosing cholangitis, and myasthenia gravis.
• The temporal association suggests a potential link between these autoimmune conditions.

Implications:

• Physicians should maintain a high index of suspicion for concurrent autoimmune disorders in pediatric IBD patients.
• Early recognition and integrated management of associated autoimmune conditions may improve patient prognosis.
• Further research is warranted to elucidate the underlying mechanisms connecting IBD and other autoimmune diseases.
