Abstract

Insights

Sclerosing skin disorders, like systemic sclerosis (SSc), can occur in patients with multiple sclerosis (MS). Interferon beta treatment may be a trigger for SSc in MS patients.

Area of Science:

  • Dermatology and Neurology
  • Autoimmune Disorders

Background:

  • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
  • Sclerosing skin disorders, particularly systemic sclerosis (SSc), are characterized by skin hardening and connective tissue abnormalities.

Observation:

  • Three patients with relapsing-remitting MS developed skin sclerosis during interferon (IFN)-beta therapy.
  • A literature review identified nine additional cases of SSc in MS patients, totaling 12 cases.
  • The majority of SSc cases were limited cutaneous SSc (8/12), with three diffuse cutaneous SSc and one antisynthetase syndrome.

Findings:

  • Systemic sclerosis (SSc) onset in MS patients occurred at a mean age of 38.3 years, significantly after MS diagnosis (mean age 25.2 years).
  • In five patients, IFN-beta treatment preceded SSc development by a mean of 4.6 years.
  • No correlation was found between SSc onset and MS disease activity; most patients (11/12) tested positive for antinuclear antibodies.

Implications:

  • The early onset of SSc in MS patients suggests a potential genetic predisposition or an IFN-beta-associated trigger.
  • These findings highlight the importance of monitoring for sclerosing skin disorders in MS patients, especially those on IFN-beta therapy.
  • Further research is warranted to elucidate the mechanisms linking MS, SSc, and IFN-beta treatment.

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Skin Diseases and Disorders

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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
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.

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
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...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
