Actinic purpura was first described by British dermatologist Thomas Bateman in 1818. Just what is actinic purpura? Well, the simplest actinic purpura definition is when elderly are more prone to bruises.
While it may appear as if a person with actinic purpura has experienced a serious trauma, it is likely that some sort of mild trauma led to the development of the purplish bruises. Large purpura spots are called ecchymosis and the smaller spots are known as petchiae.
Prevalence of Actinic Purpura
Actinic purpura is most common among seniors with roughly 11.9 percent of adults over the age of 50 having it. Prevalence is also highest among individuals who have greater exposure to the sun.What Causes Actinic purpura?
Many people seem to think that actinic purpura is the result of mineral and vitamin deficiency, but this is not the case. The list below covers some of the potential senile purpura causes:- UV rays—ultraviolet (UV) radiation, like too much exposure to the sun, can weaken the connective tissues holding the blood vessels in the matrix. Since we are exposed to sunlight over many, many years, tissues weaken and become thinner naturally in old age.
- Medications—overuse of blood thinners, such as steroids and aspirin.
- Vascular diseases—this is a class of disease affecting the blood vessels.
- Diabetes—this is defined by high blood sugar levels over a long period of time
- Thrombocytopenia—defined as deficiency of platelets in the blood, which leads to bleeding into the tissues and bruising.
- Non-thrombocytopenic—this includes blood clotting disorders, medications that impact platelet function, fragile blood vessels, inflammation of blood vessels, pressure changes during childbirth, haemangioma—which is a benign tumor of infancy—and amyloidosis, a disorder that occurs when amyloid protein deposits in tissues.
- Meningococcemia—meningococcal disease is caused by bacteria and can lead to meningitis, which is a serious illness that involves infection of the brain and spinal cord. It can also cause blood infections and a rash that can advance to purpura.
What Are the Symptoms of Actinic Purpura?
Despite what some people think, the elderly don’t suddenly wake up covered in purplish red spots. There are common actinic purpura symptoms that can appear before bruising. Some are covered in the list of symptoms below.- Thin skin
- Skin tears easily
- Irregularly shaped lesions appear that may measure one to four cm and are dark in color. They appear on hands, forearms and sometimes the face or neck.
- Adjacent skin is often thin, not very elastic.
- Bruising disappears on average in about three weeks
- Yellowish or brown stains appear where purple bruises once were
- Bruises appear with or without minor trauma
- Bruises occur as a relapsing condition
- One of the distinctions between actinic purpura and a regular bruise is that regular bruises tend to change color. Bruises that are the result of actinic purpura do not change color—they remain purple until they disappear. In some cases, a yellow of brown stain takes the place of the purple bruise for a short period of time, while in other cases, the yellowish stain is unfortunately permanent. There are people who struggle with the signs and symptoms of actinic purpura. When they have just a few lesions or bruises, they attempt to cover them up with makeup.
How to Diagnose Actinic Purpura?
When it comes to diagnosing actinic purpura, the doctor will conduct a thorough examination of the patient, including a look at their hands, legs, neck, face, and underarms. Any bruising or skin atrophy will be noted. A beam arm test is also likely. It looks at the structure and function of capillary walls. Laboratory tests such as a platelets test, capillary fragility tests, and hemostasis tests—which is a test that checks for blood clotting issues and platelet plugs—are possible.- CBC—complete blood count with a differential count
- PT, aPTT with INR—this is a coagulation profile
- Examination of urine to help rule out Henoch-Schonlein purpura, which is inflammation of the small blood vessels.
- LFT—liver function test to rule out hepatitis
- ESR or CRP—erythrocyte sedimentation rate or C-reactive protein to evaluate inflammation related to potential vascular diseases.
- RFT—renal functions test
- Skin and blood cultures
- RF—rheumatoid factor
How to Treat and Prevent Actinic Purpura
Actinic purpura doesn’t require any treatment. The lesions or bruises usually clear up on their own without causing any serious health complications. The problem with the condition is that it tends to be chronic. In other words, it recurs, and people have to live with it for the remainder of their lives. Those who find that they experience skin tearing should see a doctor for advice on how to manage the problem.While it is a new area of research, a study published in the Journal of Drugs in Dermatology indicates that a twice-daily dose of citrus bioflavonoids is a good natural remedy for senile purpura. The study showed a reduction of purpura lesions by 50 percent in a group of 70 seniors who used a “citrus bioflavonoid blend.”
More research continues, including investigations into how other supplements might impact actinic purpura. In the meantime, people who suffer from the condition are encouraged to use sun protection when outdoors to prevent future breakouts and apply skin moisturizers to help protect the skin.
In the majority of cases of actinic purpura, treatment is not necessary, but for those who do not like the appearance of bruises, there are a few options available to them. For example, your doctor can prescribe topical retinoids, which can prevent further skin aging, thus reducing the appearance of actinic purpura.
On the other hand, these retinol formulas can bring with them unwanted side effects and sometimes the cons outweigh the benefits. It may also be wise to wear protective gear to prevent injury, which can lead to further bruising.
If you want to avoid side effects, then there are some natural remedies you can try to reduce actinic purpura. One study found that seniors who took citrus bioflavonoids twice daily had a reduction in actinic purpura.
An alternative study uncovered that applying epidermal growth factor to the affected area can help skin thicken and reduce lesions.
Some studies have explored using vitamin K topically to reduce the appearance of bruising, but no studies have been conducted on vitamin K’s effects on actinic purpura, so speak to your doctor before using this technique.
Some patients may seek relief from Arnica Montana, which is derived from the Arnica plant. Arnica Montana has anti-inflammatory properties and can control bleeding which can make it effective at treating actinic purpura. Arnica Montana can be taken orally or topically. It’s important that if you have actinic purpura, you avoid foods and beverages that can thin the blood.
It is unfortunate, but for many people, actinic purpura is a condition that comes with age. The number of elderly in industrialized nations continues to increase, so the incidence of senile purpura and other age-related skin conditions is expected to rise significantly over the next few decades.
Dermatologists suggest we do whatever we can to protect our skin from an early age. If and when something like senile purpura occurs, it is important to understand that you’re not alone and that you can reach out to doctors and dermatologists for guidance.
