What autoimmune disease causes an itchy rash? Some autoimmune diseases that may cause an itchy rash are cutaneous lupus, oral lichen planus, and erythrodermic psoriasis.
Like systemic lupus, cutaneous lupus is caused by an autoimmune response, meaning the body attacks its own tissues and organs. In cutaneous lupus, the immune system targets skin cells, causing inflammation that leads to red, thick, and often scaly rashes and sores that may burn or itch.
Skin inflammation and rashes can cause redness, pain, itching and dryness and be challenging to diagnose and manage. Common inflammatory skin conditions include dermatitis, poison ivy and poison oak, and drug rashes.
The causes of skin itching, or pruritis, are usually harmless. They are often temporary issues such as dry skin or a bug bite. Less commonly, nerves, kidneys, thyroid, or liver issues can cause itching sensations without necessarily causing a rash.
If this system is not functioning well, certain cytokines can be expressed abnormally. In your case, it would appear that when you get a bit run down and as your immune system weakens, you have a tendency to histamines and it is this substance that causes you to itch.
Dry, itchy skin is often a sign of a vitamin D deficiency. As vitamin D is created through skin exposure to the sun and cholesterol in the skin, in the winter months, when sunlight exposure is less, people often experience dry, itchy skin attributing it to the cold weather.
Itching with kidney disease can be generalized, or it can occur in specific parts of the body. Common areas for this type of itching include the head, arms, back, and abdomen. It also tends to be worse at night, which can disturb your sleep.
Disease Overview
Prurigo nodularis (PN) is a chronic inflammatory skin disease where an extremely itchy, symmetrically distributed rash appears most commonly on the arms, legs, the upper back and/or the abdomen. The itch associated with PN is so severe that it often interferes with sleep and psychological wellbeing.
C-Reactive Protein (CRP): A high CRP can be a marker for inflammation and immune activity and help screen for autoimmune disorders.
Duke dermatologists diagnose autoimmune skin diseases like pemphigus, pemphigoid, scleroderma, morphea, dermatomyositis, dermatitis herpetiformis, vasculitis, lupus, and Sjögren's syndrome -- all of which occur when the body's immune system attacks healthy skin.
Systemic sodium channel blockers, such as carbamazepine and oxcarbazepine are the first-line choice, as they calm the ectopic neuronal firing. Gabapentin and pregabalin are commonly prescribed for patients with brachioradial pruritus and appear effective at similar concentrations as used for neuropathic pain.
Other possible symptoms of Sjögren's syndrome can include: dry, itchy skin. severe tiredness and exhaustion. vaginal dryness in women, which can make sex painful.
Common symptoms include fatigue, hair loss, sun sensitivity, painful and swollen joints, unexplained fever, skin rashes, and kidney problems. There is no one test for SLE. Usually, your doctor will ask you about your family and personal medical history and your symptoms. Your doctor will also do some laboratory tests.
Itching on the whole body might be a symptom of an underlying illness, such as liver disease, kidney disease, anemia, diabetes, thyroid problems and certain cancers. Nerve disorders. Examples include multiple sclerosis, pinched nerves and shingles (herpes zoster). Psychiatric conditions.
What does diabetes itching feel like? If you have diabetes, itching can be intense. It's an irritating feeling that makes it hard not to scratch, but scratching can make the itch worse. You can itch anywhere, but if you have nerve damage (neuropathy) associated with diabetes, your lower legs may itch.
It's important to note that it isn't strictly true that magnesium does help itchy skin or that a magnesium deficiency causes dry skin. However, one of the many skincare benefits of magnesium is that it can help reduce the inflammation caused by conditions which lead to dry and itchy skin, such as eczema.
Vitamin D. Studies have concluded that people who suffer from eczema and other similar skin conditions tend to have lower levels of vitamin D than the rest of the population. Taking a vitamin D supplement therefore increases your levels, helping to reduce the severity of itchy skin.
Dry skin: Your body loses moisture at night, which can make your skin itchy. Hormonal changes: At night, your body doesn't produce as many hormones as it does during the day and certain hormones reduce inflammation (swelling). As you have fewer hormones at night, your skin could be itchy.
Signs of a weak immune system include frequent colds, infections, digestive problems, delayed wound healing, skin infections, fatigue, organ problem, delayed growth, a blood disorder, and autoimmune diseases. The immune system helps protect the body from harmful pathogens and other environmental risks.
