Insights

Children with autoimmune hepatitis and celiac disease achieved sustained remission more often after treatment. A gluten-free diet may improve long-term outcomes in these patients.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Immunology

Background:

  • Autoimmune liver disease (AILD) frequently coexists with celiac disease (CD).
  • Long-term treatment responses in patients with coexisting AILD and CD are not well-documented.
  • Autoimmune hepatitis (AIH) is a common form of AILD.

Purpose of the Study:

  • To investigate the clinical features of autoimmune hepatitis (AIH) in children with coexisting celiac disease (CD).
  • To analyze the long-term response to immunosuppressive therapy in pediatric patients with AIH and CD.
  • To compare treatment outcomes between AIH patients with and without CD.

Main Methods:

  • Retrospective and prospective single-center study.
  • Inclusion of 79 patients with AIH, with 15 diagnosed with CD.
  • Evaluation of immunosuppressive treatment (prednisone, azathioprine, cyclosporine) and gluten-free diet adherence.

Main Results:

  • 19% of AIH patients had CD; these patients were more often female and diagnosed earlier.
  • All 15 AIH patients with CD on a gluten-free diet achieved sustained remission.
  • Significantly higher proportion (33%) of AIH patients with CD achieved treatment-free remission compared to AIH patients without CD (8%).

Conclusions:

  • Coexistence of celiac disease in autoimmune hepatitis may lead to a higher rate of treatment-free sustained remission.
  • A gluten-free diet might have a long-term adjuvant effect in managing autoimmune hepatitis.
  • Further research is warranted to confirm the impact of gluten-free diet on AIH prognosis.

Type I Diabetes I: Introduction

Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...

Gastritis-II: Pathophysiology

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

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.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
