Allergic purpura is a special type of vasculitis and also a hypersensitivity disorder. It commonly occurs in adolescents and children aged 5 to 14, with a higher incidence rate in the spring and autumn seasons. The disease frequently relapses and cannot be completely cured. The most common causes of allergic purpura include infections, medications, and foods. Infections are the most frequent cause, such as bacteria, viruses, parasites, tuberculosis, etc. If it is merely a cutaneous form, no special treatment is required at this time, and bed rest alone can alleviate the condition. If there is the presence of blood or protein in the urine, and renal biopsy shows a large number of crescents, it then indicates a serious aggravation of the condition.

Is allergic purpura contagious?

Allergic purpura is not a contagious disease; it is an autoimmune disorder, and therefore it is not transmissible. This condition is a self-limiting disease commonly found in adolescents and children. It mainly comes in four types: simple, renal, abdominal, and articular. Common symptoms include purpura on the limbs and body, and it may also involve abdominal pain, joint pain, and hematuria among other organ impairments. During the acute phase, bed rest is required. Sometimes, when the kidneys are affected, corticosteroids are necessary for timely treatment. If there is joint swelling and pain, nonsteroidal anti-inflammatory drugs can be used to alleviate pain, and antispasmodic analgesics can be used for abdominal pain.

Is allergic purpura with abdominal pain easy to treat?

Allergic purpura with abdominal pain, also known as abdominal allergic purpura, involves gastrointestinal symptoms associated with allergic purpura, primarily characterized by episodic severe abdominal pain, usually around the navel or lower abdomen, and may sometimes be accompanied by vomiting. Treatment typically involves bed rest, actively identifying the cause, controlling infections, and supplementing relevant vitamins. It's also important to check for any symptoms of gastrointestinal bleeding. If there are signs of gastrointestinal bleeding, strict dietary management is necessary, blood transfusions may be required when needed, and the healing of the gastrointestinal tract must be monitored. Medications to suppress acid or protect the gastric mucosa could be considered. Generally, the prognosis for allergic purpura is favorable, though very few severe cases may experience gastrointestinal complications such as bleeding, intussusception, or even necrosis. Although the prognosis is generally good, relapse is common. (Please use medications under the guidance of a professional physician and do not self-medicate.)

What causes allergic purpura?

Allergic purpura commonly occurs in adolescents and children, characterized by frequent relapses and being intractable. It is primarily seen in youth aged between 5 to 14 years. As they age and their immunity strengthens, the frequency of episodes gradually decreases. The most common causes of allergic purpura include infections such as bacteria, viruses, parasites, mycoplasma infections, and allergies to medications and foods, with food allergies mainly stemming from high-protein foods like fish and shrimp, which can easily trigger allergic reactions. Therefore, once skin purpura or proteinuria appears, it is crucial to rest in bed until the pain and proteinuria dissipate and the purpura eases. During treatment, it is also important to avoid cold exposure and overexertion.

Is allergic purpura nephritis contagious?

Henoch-Schönlein purpura nephritis and allergic purpura are not infectious diseases; there is no contagious element involved. Henoch-Schönlein purpura nephritis is actually kidney damage caused by allergic purpura, which is an allergic disease itself. Patients suffer from an abnormal immune response in the body’s immune system after coming into contact with allergenic drugs or foods, leading to necrotizing vasculitis. This disease is unrelated to pathogens. Generally, there is no direct damage to the kidneys caused by a specific pathogen in this disease, nor do patients carry pathogens that can cause Henoch-Schönlein purpura nephritis, such as bacteria or viruses, thus making the disease non-contagious.

Mild symptoms of allergic purpura

Allergic purpura mainly includes three pathological types. The symptoms of the mild type mainly involve changes in the skin, primarily purpura-like rashes around the lower legs and ankle joints. If there are only skin lesions, it is considered a very mild case of allergic purpura. Additionally, more severe cases may involve kidney impairment, such as the presence of protein in the urine. Some patients primarily experience joint pain, also known as the arthritic type. Another group of patients presents mainly with sudden abdominal pain, primarily known as the abdominal type. Therefore, mild symptoms of allergic purpura might just be typical rashes. As long as there is no involvement of the visceral system, it is considered relatively mild.
