Selective IgG subclass deficiencies, like IgG1, can manifest with autoimmune disorders and severe infections. This case highlights the link between latent humoral defects and autoimmunity, emphasizing the need for thorough immune evaluation.
Area of Science:
- Immunology
- Endocrinology
- Infectious Diseases
Background:
- Antibody deficiencies, such as selective IgA deficiency, are linked to autoimmunity and severe infections.
- Information on selective IgG subclass deficiencies and their association with autoimmune conditions remains limited.
Observation:
- A 19-year-old woman presented with a severe Campylobacter infection.
- She had a complex, previously undiagnosed immune disorder.
- This included selective IgG1 immunodeficiency, Hashimoto's autoimmune thyroiditis, hypothyroidism, and Addison's disease.
Findings:
- The patient's complex immune disorder involved selective IgG1 immunodeficiency and multiple autoimmune conditions.
- The severe Campylobacter infection underscored the risks associated with undiagnosed humoral defects.
- Autoimmunity in latent humoral defects presents complex pathophysiological mechanisms.
Implications:
- This case highlights the critical need to investigate potential immune deficiencies in patients with unexplained autoimmunity.
- Early diagnosis and management of selective IgG subclass deficiencies can prevent severe infections and complications.
- Further research into the pathophysiology of autoimmunity in latent humoral defects is warranted.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
