Can allergic conjunctivitis be cured?

Allergic capillary inflammation causes damage to many organs such as joints, skin, heart, digestive tract... The early detection and treatment of allergic capillary inflammation helps to reduce symptoms and avoid complications.

Allergic vasculitis also has many other names such as Schonlein-Henoch vasculitis syndrome, anaphylactic purpura, purpura... is a disease related to the immune system, causing a condition Allergic reactions with diffuse damage to the microvascular system in many different organs are common, mainly joints, skin lesions, kidneys, intestines...
The disease is more common in children with the incidence before 5 age is about 50%, 3–10 years old is 75%. Prevalence by sex, mainly seen in men, the incidence is 2 times higher than that of women.
Pathogenesis:
Common in people with atopy, when the body is exposed to the allergen, then antigen and antibody reactions occur. Because the immune reaction between antigens and antibodies takes place in the endothelium (mainly capillaries). This antigen-antibody reaction results in the release of chemical mediators and the deposition of immune complexes in the mucosal layer of the capillaries. This chemical mediator and immune complex will cause damage, increase capillary permeability leading to bleeding, bleeding may occur on the skin or on other organs.
The cause of the disease is unknown. There are some risk factors that cause the disease such as:
People with atopy, atopic dermatitis, allergies to strange foods, changes in weather... When the body is infected with certain strains of bacteria or viruses such as group A streptococcus, Mycoplasma, staphylococcus, Varicella virus, cytomegalovirus, Epstein-Barr virus, Parvovirus B19, Campylobacter... Some cases appear after patients use certain drugs, after vaccination or after an insect sting.

Signs of allergic capillary disease appear on many different organs of the body:
Skin manifestations: About 50% of patients experience the first symptoms on the skin. The manifestation is the appearance of hemorrhagic spots in the folds of the limbs, around the ankles, thighs, buttocks, arms... These hemorrhages are not itchy, dotted. In addition, this purpura is rare on the trunk, sometimes appearing on the ears, nose and genitals. If only these purpura is present, it is sometimes easily confused with other diseases such as thrombocytopenic purpura, lupus erythematosus... Joint manifestations: This symptom is common in about 75% of inflammatory patients. Capillary allergies such as purpura on the ankles, knees, elbows, rarely in the wrists and hands. Hemorrhage causes pain at these sites, limited range of motion, peri-articular edema accompanied by pain in tendons, arthritis... Gastrointestinal tract: Patients with allergic capillaritis have gastrointestinal bleeding with symptoms. symptoms such as abdominal pain around the navel, which may be severe or continuous, vomiting and nausea, may vomit blood, pass black stools... Kidney damage: Usually can occur in the acute stage . Patients with symptoms of gross or microscopic hematuria, presence of proteinuria.

There are also some less common manifestations but there are some dangerous complications such as:
Orchitis: Causes painful swelling of the testicles, which can go away on their own after a few days. Cardiovascular: Myocarditis, pericarditis, myocardial infarction, arrhythmia, congestive heart failure due to allergic capillary inflammation. Lungs: The pulmonary manifestations are hemorrhages in the alveoli. This is a very rare complication of allergic conjunctivitis, but very serious. Which expression. Central Nervous System: May cause only headaches, sometimes causing meningitis, pressure on the central nervous system, causing motor paralysis, behavioral disturbances, coma... Eyes: Hemorrhagic retinitis fundus, seen in a small number of patients.

Allergic capillary disease is a disease that currently does not have any specific treatment, so the treatment is mainly to treat bleeding symptoms and thereby prevent dangerous hemorrhagic complications. .
The main method of treatment of allergic capillary disease is mainly based on medicine with drugs:
Anti-allergic: Using antihistamines, reducing inflammation in the capillaries. Circuit protection. Anti-inflammatory analgesics: For patients with mild pain symptoms, non-steroidal anti-inflammatory drugs or steroid anti-inflammatory drugs can be used for patients, in cases where the patient has severe kidney damage. In case the patient shows signs of infection, the combination of antibiotics should be used according to the results of the antibiogram. In case of heavy bleeding causing severe anemia, a red blood cell transfusion will be indicated. Immunosuppressants: Used in patients with severe renal impairment.

In addition, it is necessary to take care measures such as:
Eat enough nutrients, supplement vitamin C to strengthen resistance and increase stability of the vascular wall. Patients should limit movement, should rest from 1 to 2 months. In summary, allergic conjunctivitis has no specific treatment. However, the disease is treated and controlled with symptomatic treatments. Symptomatic treatment helps limit serious complications that may occur. Therefore, when having symptoms of similar disease, it is necessary to consult a reputable medical facility.
