Summary
Atopic dermatitis (AD) is linked to genetic factors like the filaggrin (FLG) gene and family history. It can lead to other allergic conditions and associated diseases, impacting overall health and sleep quality.
Area of Science:
- Dermatology
- Genetics
- Allergology
Background:
- Atopic dermatitis (AD) is a common inflammatory skin condition.
- Genetics, particularly filaggrin (FLG) gene mutations, plays a significant role in AD development.
- A family history of atopic or allergic diseases increases the risk of developing AD.
Purpose of the Study:
- To discuss the various risk factors associated with atopic dermatitis.
- To explore the common comorbidities observed in patients with atopic dermatitis.
- To provide a comprehensive overview of AD pathogenesis and associated conditions.
Main Methods:
- Literature review of genetic and epidemiological studies on atopic dermatitis.
- Analysis of the association between FLG gene mutations and AD.
- Examination of the relationship between family history and AD prevalence.
- Review of studies on the "atopic march" and associated comorbidities.
Main Results:
- Filaggrin (FLG) gene mutations are a key genetic risk factor for AD.
- Positive family history of atopic/allergic disease significantly elevates AD risk.
- AD often precedes other atopic conditions (asthma, allergic rhinitis, food allergies) in the "atopic march".
- Comorbidities include increased susceptibility to skin infections, neuropsychiatric disorders (ADHD, ASD), and poor sleep quality.
Conclusions:
- Understanding genetic and familial risk factors is crucial for AD prevention and management.
- AD serves as an early indicator for the "atopic march", necessitating early intervention.
- The high prevalence of comorbidities highlights the systemic impact of AD and the need for holistic patient care.

01:29Asthma-I: Introduction
2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

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.
