Does Linear IgA go away?
Linear IgA bullous dermatosis (LABD) tends to wax and wane in severity. Drug-induced cases usually resolve spontaneously when the causative agent is stopped. Cutaneous lesions usually heal without scarring while mucous membrane lesions leave scars and pose considerable morbidity.
How common is linear IgA disease?
Linear IgA bullous dermatosis is rare; the annual incidence in some countries is reported to be approximately 0.5–2 cases per million people. It can occur in both adults and children. In adults, disease onset is more common in the sixth decade.
How do you get linear IgA disease?
The exact cause of Linear IgA Disease is unknown however it is considered to be an “autoimmune” disease. The body’s immune system produces antibodies known as Immunoglobulin A (IgA) which are incorrectly deposited in the top layer of the skin in a line – hence the term “linear”.
How long does linear IgA last?
The mean duration of idiopathic linear IgA dermatosis of childhood is 3.9 years, ranging from 2.1-7.9 years. Remission has been reported to occur in 64% of children, in most cases within 2 years. Disease of adults is more protracted, with a mean duration of 5.6 years, lasting anywhere from 1-15 years.
What causes Linear IgA dermatosis?
Antilaminin 332 antibodies are typically seen in malignancy-associated mucous membrane pemphigoid (MMP). The etiology underlying drug-induced linear IgA dermatosis remains elusive but is speculated to be caused by an immune response towards a drug-derived hapten-protein antigen.
What is IgA dermatosis?
Linear IgA bullous dermatosis (LABD), also known as linear IgA disease, is a rare, idiopathic or drug-induced autoimmune blistering disease characterized by the linear deposition of IgA at the dermoepidermal junction.
What is IgA Pemphigus?
IgA pemphigus is a rare autoimmune blistering disease characterized by painful and pruritic vesiculopustular eruptions. These eruptions form as a result of circulating IgA antibodies against keratinocyte cell surface components responsible for cell to cell adherence.
What causes chronic bullous disease of childhood?
We are not sure what causes autoimmune disorders such as chronic bullous disease of childhood. More research is needed to discover what triggers antibodies to attack the body instead of fighting foreign invaders like viruses. The condition is not inherited, so cannot be passed on to other children or adults.
Can low IgA cause fatigue?
Fatigue Is Common in Immunoglobulin G Subclass Deficiency and Correlates With Inflammatory Response and Need for Immunoglobulin Replacement Therapy. Purpose: Individuals with immunoglobulin G deficiency (IgGsd) often complain of fatigue. The correlation between systemic inflammation and fatigue is unknown.
What does IgA deficiency mean?
Overview. Selective IgA deficiency is an immune system condition in which you lack or don’t have enough immunoglobulin A (IgA), a protein that fights infection (antibody). Most people with selective IgA deficiency don’t have recurrent infections.
What is linear dermatitis?
What causes IgA pemphigus?
The exact cause of IgA pemphigus is unclear. IgA autoantibodies bind to desmogleins or desmocollins, the cells responsible for adhesion between cells. In SPD-type IgA pemphigus, the autoantigen is described as desmocollin 1, one of the desmosomal cadherins, the glycoproteins that maintain the shape of a cell.
Can kids get bullous pemphigoid?
Bullous pemphigoid (BP) is an autoimmune subepidermal blistering disease that commonly affects elderly individuals. The disease is very rare in children, and most cases occur in school-aged children (generally, those older than 8 years).
