Immune reconstitution therapy (IRT) is a relatively new and highly effective treatment option for multiple sclerosis (MS). Uncertainty regarding the development of autoimmune disorders (ADs) after some therapies remains. The aim of this study was to assess new AD development after IRT in MS patients and to describe the nature of those ADs and the time to onset. A total of 179 patients with relapsing multiple sclerosis (37 after autologous haematopoietic stem cell transplantation (AHSCT), 19 after alemtuzumab (ALE) and 123 after cladribine (CLA) treatment) over a ten year period were included in the study. ADs were observed in 6 patients (16.2%) after AHSCT, 8 patients (42.1%) after ALE and 2 patients (1.6%) after CLA treatment. ADs developed earlier after ALE infusions, but later after AHSCT except for cytopenias. Neurologists should be attentive to the development of secondary ADs after ALE and AHSCT in MS patients.

Autoimmune Disorders01:29

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.

T Cell Types and Functions01:24

T Cell Types and Functions

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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Myasthenia Gravis: Overview and Treatment

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...
