Firstly, allergic purpura commonly occurs in adolescents and children, mainly between the ages of 5 to 14, and is frequent during the spring and autumn seasons. The most common causes of allergic purpura are infections, drug and food allergies, with infections being the most prevalent cause, such as bacterial, viral, and parasitic infections. Allergic purpura cannot be cured and often relapses. During the acute phase, it is primarily recommended to rest in bed, and to eat a light diet. It is advisable to consume fresh fruits and vegetables, such as oranges, grapes, grapefruits, and kiwis, which are rich in vitamin C, as well as various green leafy vegetables. These foods, rich in vitamin C, are beneficial for recovery and good for the body. Additionally, foods like seafood and mangoes, as well as previously untried fruits and foods, are not recommended during this phase to avoid triggering allergic reactions or worsening the condition.

Can allergic purpura be cured completely?

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.

How many days will allergic purpura take to fade?

The symptoms of the rash from allergic purpura generally subside naturally after about 7 to 10 days. However, if care is not taken in daily life, there is a high likelihood of recurrence of the rash. Patients with allergic purpura should avoid vigorous activities such as fast running and should also avoid getting chilled and infections, as both cold and infections could exacerbate the condition. Additionally, patients should consume less of foods like shrimp and crab, which may trigger allergic reactions.

Are there many children with allergic purpura?

Firstly, allergic purpura is commonly found in adolescents and children, with children being the most commonly affected, particularly between the ages of 8 to 15. It typically occurs during the spring and autumn seasons. The most common clinical manifestations are bleeding spots on the lower limbs, hematuria, black stools, and joint pain, which are the most typical clinical presentations. If there are only bleeding spots on the skin, no special treatment is required at this time; rest in bed is necessary, and these bruises can be absorbed. Once the kidneys are involved, it indicates a relatively severe condition, and at this time, active and standard treatment is necessary, including the need to improve routine urine and kidney function indicators. If protein quantification is relatively high, then glucocorticoids are needed, combined with anti-allergic medication. (Medication should be taken under the guidance of a doctor.)

Precautions for Allergic Purpura

Allergic purpura is a common allergic disorder, also known as vasculitis, and occurs more frequently in adolescent males. Adults can also be affected, but it is less common, and the majority of cases are due to infections, such as bacterial, viral, or parasitic infections. Food or drug allergies are also part of the causes of allergic purpura. For adolescents who develop allergic purpura, infections should be considered first, followed by allergies. It's important to maintain a light diet, drink plenty of water, wear a mask when going out to prevent upper respiratory infections, and control the intake of high-protein foods such as fish, shrimp, eggs, milk, and lean meat. As for fruits, including mangoes, some people can be triggered to have allergic purpura, especially fruits they have not been exposed to before; it's best to minimize contact with unfamiliar fruits to avoid inducing an allergic purpura attack.

Is allergic purpura prone to recurrence?

First and foremost, allergic purpura refers to a hemorrhagic disease that affects the capillaries in the skin or other organs; it is categorized as a rheumatic immune disease. It primarily occurs in adolescents and children aged between five to fourteen years, and cannot be cured. The disease is prone to recurring, which is its main clinical characteristic. The primary causes are infections, drugs, or food allergies, with infections being the most significant factor. Therefore, upon the appearance of skin purpura or bleeding spots, joint swelling, or signs such as hematuria and proteinuria, timely and comprehensive examinations should be conducted for diagnosis. Once the kidneys are involved, it is essential to rest in bed until the proteinuria alleviates. Moreover, it is crucial to conduct a 24-hour urinary protein quantification to assess the extent of kidney damage. If there is a significant amount of proteinuria, it is advisable to promptly perform a renal biopsy to clarify the type of pathology.
