Summary
A patient with severe psoriasis and myasthenia gravis experienced skin lesion clearance and symptom remission with ixekizumab. This interleukin-17 (IL-17) inhibitor allowed for corticosteroid tapering, suggesting IL-17
Area of Science:
- Immunodermatology
- Neuromuscular Diseases
Background:
- Psoriasis management is complicated by comorbidities.
- Myasthenia gravis (MG) is an autoimmune disorder affecting neuromuscular junctions.
Observation:
- A 55-year-old female with severe chronic plaque psoriasis and steroid-dependent myasthenia gravis (MG) was treated with ixekizumab.
- Previous treatments including topical corticosteroids and phototherapy were ineffective for her psoriasis.
Findings:
- Ixekizumab, an anti-interleukin-17 (IL-17) antibody, achieved complete clearance of psoriatic lesions.
- The patient experienced significant remission of myasthenic symptoms, enabling a reduction in oral corticosteroid dosage.
Implications:
- This case suggests a potential role for IL-17 cytokines in the pathogenesis of myasthenia gravis.
- Ixekizumab may represent a novel therapeutic option for patients with coexisting psoriasis and steroid-dependent myasthenia gravis.

T Cell Types and Functions
1.4K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Myasthenia Gravis: Overview and Treatment
2.0K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Autoimmune Disorders
703
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.

The JAK-STAT Signaling Pathway
9.4K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Asthma: Pathogenesis and Management
744
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.

Myasthenia Gravis: Diagnostic Tests
1.4K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
