One of the things that can trigger an episode of angioedema is systemic lupus erythematosus (SLE). This disease is often simply referred to as lupus. It is autoimmune in nature.
Along with being autoimmune, SLE is also systemic in nature. It can affect various locations and lead to symptoms in numerous areas throughout the body. Many people with this disease have the malar rash that is commonly associated with the condition. Other symptoms can also affect the skin. Various heart-related issues can also occur. For instance, the patient may have certain kinds of inflammation of the heart, including amongst others, endocarditis. Atherosclerosis may result in those with lupus.
Many patients with SLE end up developing anemia -- that is, a decrease in red blood cells (anemia can also refer to a lower level of hemoglobin in the person's blood). Having seizures is another possible symptom. The person might be impacted by headaches. A particular disorder known as polyneuropathy can occur. In this condition, numerous peripheral nerves in the patient's body fail, at the same time, to function properly. Related to the kidneys, both blood and protein might be found in the urine.
No one item is the lone underlying cause for systemic lupus erythematosus. However, various things seem to be factors, including genetics and environmental triggers.
There are various methods used to diagnose a case of SLE. In general, the most widely used diagnostic techniques involve checking for antinuclear antibodies (ANA). However, general ANA testing may give positive results in people who do not have SLE. Subtypes that are more specific to the condition can also be checked for, in which case a positive result is more directly correlated to lupus. Other things may also be used for diagnosis, including various tests (kidney and liver function, as well as others), and symptomatic criteria.
Methods of treating SLE generally aim both to avoid episodes and lessen their length of time and severity when they do happen. Different medications can be involved in the treatment of this condition. Some of these are intended to modify the course of the disease, while others are intended to provide relief for symptoms. Certain modifications to lifestyle might also be employed. If the patient develops lupus nephritis and eventually end-stage kidney disease, then a kidney transplant might be performed.
