Gastritis-II: Pathophysiology

1.1K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
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...

Autoimmune Disorders

1.3K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Summary
This summary is machine-generated.

Autoimmune Polyglandular Syndrome type 2 (APS 2) involves Addison's disease (AD) with other autoimmune disorders. This case highlights the importance of suspecting AD and screening for other conditions in rare autoimmune disease diagnoses.

Area of Science:

  • Endocrinology
  • Immunology
  • Internal Medicine

Background:

  • Autoimmune Polyglandular Syndrome type 2 (APS 2) is a rare endocrine disorder characterized by Addison's disease (AD) combined with autoimmune thyroid disease and/or Type 1 diabetes mellitus (T1DM).
  • A less common presentation involves AD, Graves' disease, and T1DM.
  • Early diagnosis and management are crucial for patient outcomes.

Observation:

  • A 42-year-old woman presented with symptoms including asthenia, dizziness, nausea, and vomiting, with a history of Graves' disease, type 2 diabetes mellitus, and hypertension.
  • Physical examination revealed cutaneous hyperpigmentation.
  • Laboratory results showed low serum cortisol, elevated ACTH, suppressed aldosterone, and positive 21-hydroxylase antibodies, indicative of Addison's disease.

Findings:

  • The patient was diagnosed with Addison's disease, confirmed by hormonal assays and positive autoantibodies.
  • Despite a history of type 2 diabetes, positive anti-GAD antibodies suggested an autoimmune component potentially related to T1DM.
  • The patient responded well to treatment with insulin, prednisolone, and fludrocortisone.

Implications:

  • This case underscores the necessity of maintaining a high index of clinical suspicion for Addison's disease, even with atypical presentations.
  • Screening for other autoimmune conditions is vital in patients diagnosed with rare autoimmune diseases to identify or exclude APS.
  • Prompt diagnosis and comprehensive management of associated autoimmune disorders can significantly improve patient prognosis.
