Summary
Epigenetic changes from environmental factors may explain the unknown cause of autoimmune hepatitis. Missing heritability could stem from gene interactions or inherited epigenetic marks, suggesting new therapeutic avenues.
Area of Science:
- Hepatology
- Immunology
- Epigenetics
Background:
- Autoimmune hepatitis (AIH) etiology remains unclear, with non-specific genetic associations.
- Understanding AIH causality and heritability is crucial for improved prevention and management.
Purpose of the Study:
- To explore epigenetic and genetic mechanisms behind AIH's missing causality and heritability.
- To assess the potential of these mechanisms in AIH pathogenesis and therapy.
Main Methods:
- Systematic review of English abstracts from PubMed.
- Analysis of 210 full-length articles on AIH genetics and epigenetics.
Main Results:
- Environmental factors inducing epigenetic changes (e.g., diet, toxins) are prime candidates for AIH causality.
- Epistatic gene interactions and transgenerational epigenetic inheritance may explain AIH's missing heritability.
- Potential management includes lifestyle changes, supplements, and epigenetic editing.
Conclusions:
- Epigenetic modifications and environmental factors likely contribute to AIH causality.
- Epistatic gene interactions and transgenerational epigenetic inheritance may explain AIH heritability.
- Further research into these areas is warranted for therapeutic development.

01:29Autoimmune Disorders
621
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.

01:21Causality in Epidemiology
684
Causality or causation is a fundamental concept in epidemiology, vital for understanding the relationships between various factors and health outcomes. Despite its importance, there's no single, universally accepted definition of causality within the discipline. Drawing from a systematic review, causality in epidemiology encompasses several definitions, including production, necessary and sufficient, sufficient-component, counterfactual, and probabilistic models. Each has its strengths and...

01:06Heritability
275
Heritability is a statistical concept that measures the degree to which genetic differences among individuals contribute to trait variations within a population. It is a fundamental idea in genetics, often prone to misinterpretation. Heritability is expressed as a percentage, reflecting the proportion of variation in a specific trait across a population that can be linked to genetic differences. However, it's important to understand that heritability does not determine how "genetic"...

01:28Criteria for Causality: Bradford Hill Criteria - II
537
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

01:30Criteria for Causality: Bradford Hill Criteria - I
442
The Bradford Hill criteria are a group of principles that provide a framework to determine a causal relationship between a specific factor and a disease. There are nine criteria that are pivotal in assessing causality in epidemiological studies. Here's a closer look at Strength, Consistency, Specificity, and Temporality criteria with definitions and examples:

01:17Gastritis-II: Pathophysiology
463
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...
