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 nephritis contagious?

Kidney damage caused by allergic purpura is called allergic purpuric nephritis. The main mechanism of allergic purpuric nephritis is the deposition of immune complexes in the kidneys, causing hematuria, proteinuria, edema, and hypertension. Severe cases of purpuric nephritis may also lead to renal failure. Additionally, patients with allergic purpuric nephritis exhibit systemic symptoms such as skin purpura, abdominal pain, joint pain, and melena. Allergic purpuric nephritis usually occurs in children, and it is not contagious. Unlike viral hepatitis, tuberculosis, and dysentery, it does not spread through respiratory, digestive, or blood pathways.

What medicine is taken for allergic purpura?

The medication for allergic purpura should be determined based on the severity of the patient's condition. If the patient only shows symptoms like rashes, the focus should be on reducing the rashes, and medications such as compound glycyrrhizin and desloratadine can be used for their anti-allergic effects. If the main clinical manifestation of allergic purpura is joint pain, some non-steroidal pain relief medications can be added for pain relief. However, if the patient primarily exhibits involvement of internal organs, such as gastrointestinal involvement in allergic purpura starting with abdominal pain, or kidney damage marked by significant proteinuria, then corticosteroids and immunosuppressants should be considered for treatment. (Please use medications under the guidance of a doctor).

Can people with allergic purpura take baths?

Patients with allergic purpura can take baths, but the water temperature should not be too hot. This is because excessive heat or vigorous exercise can potentially trigger a recurrence of allergic purpura. Additionally, patients should avoid getting cold to reduce the risk of infection, as infections can also provoke episodes of allergic purpura. During an episode of allergic purpura, it is necessary to take some anti-allergy medications and medications that reduce rashes, such as desloratadine dispersible tablets and compound glycyrrhizin tablets. If there is significant involvement of vital organs, such as the kidneys or gastrointestinal tract, some patients may also need to use corticosteroids. (Medication should be taken under the guidance of a doctor.)

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.

Is allergic purpura nephritis easy to treat?

Allergic purpura nephritis is essentially a kidney complication caused by allergic purpura. The main symptoms are that the patient first presents with scattered purple spots on the lower limbs, known as allergic purpura. Subsequently, routine urine tests reveal hematuria or proteinuria, allowing for a diagnosis of allergic purpura nephritis. It cannot be completely cured. Currently, treatment first requires complete quantification of urine protein and a renal biopsy to confirm whether it is allergic purpura nephritis and its severity. Generally, it involves the use of steroids. Typical treatment involves firstly avoiding allergens, so any substances that cause allergies should not be contacted to prevent triggering allergic purpura, and thus prevent the recurrence of purpura nephritis. Additionally, it involves adhering to a low-salt, low-fat diet, and avoiding catching colds or staying up late.
