Fatal allergy due to tick bite: Life-threatening risk in consuming mammal meat

Alpha-gal syndrome, which is an increasingly common and yet unknown health threat worldwide, draws attention as a condition that develops as a result of tick bites and causes fatal allergic reactions to the consumption of mammal meat. This disease, called Alpha-gal Syndrome (AGS) in the English literature, occurs with the immune system response triggered by a molecule called alpha-gal, which enters the body through a tick bite.

What happened?

Alpha-gal syndrome is a delayed allergic reaction to the alpha-gal molecule that enters the body after the bite of tick species such as Ixodes and Amblyomma. After the bite, the body begins to produce antibodies against this molecule, and serious allergic reactions may occur when mammal meat (such as beef, pork, mutton) is consumed later. Reactions can usually be seen within 3-6 hours, sometimes longer.

The most common symptoms of the disease include skin itching, hives, shortness of breath, nausea, vomiting and even anaphylactic shock. In case of anaphylaxis, an emergency injection of adrenaline may be required. According to data from the US Center for Disease Control and Prevention (CDC), cases of alpha-gal syndrome have increased significantly over the past decade. While approximately 24 thousand cases were reported in 2010, this number has reached 110 thousand in 2022.

Background

After alpha-gal syndrome was first identified in the USA in 2009, research on the geographical distribution of the disease and its relationship with tick species intensified. While the disease was initially seen only in the southern and central regions of the United States, it has now begun to be reported in Europe, Australia and some parts of Asia. The incidence of the disease is higher in areas where tick species such as Amblyomma americanum (star tick) and Ixodes scapularis (a type of deer tick) are common.

Diagnosis of the disease is usually made by evaluating the symptoms and the patient's tick bite history. The presence of alpha-gal antibodies can be detected through blood tests. However, experts also emphasize that the disease is not yet fully understood and treatment protocols are not standardized.

Why is it important?

Alpha-gal syndrome poses a serious threat to both individual and social health. First of all, because the disease is not yet widely known, many people are not aware of the risk they are exposed to after a tick bite. This is especially vital for people who live in rural areas or engage in nature activities. Secondly, the fact that there is no definitive method for the treatment of the disease yet and patients have to make serious restrictions on their diets significantly affects the quality of life.

The increasing number of cases of the disease also worries public health authorities. In the USA, the CDC is running various campaigns to monitor the spread of the disease and raise public awareness. In the European Union, there is no comprehensive data yet on the prevalence of the disease, but the number of cases is increasing in some countries.

What do experts and parties say?

Dr., an expert at the National Institute of Allergy and Infectious Diseases (NIAID) in the USA. [Name omitted] states that alpha-gal syndrome has not yet been adequately studied and treatment options are limited. Dr. [Name not given] said, "Although the mechanism of the disease is not fully understood, we know that the immune response to the alpha-gal molecule that enters the body after a tick bite causes allergic reactions to the consumption of mammal meat. However, it is not yet clear why the disease is seen in some people and not in others."

The National Health Service (NHS) in England has published a series of guides to inform the public about the diagnosis and treatment of the disease. The NHS recommends that people who have been bitten by a tick should contact a healthcare provider and seek urgent medical attention if symptoms occur. He also points out that the disease cannot yet be treated with vaccine or medication, so prevention is important first.

What to watch next?

To protect yourself from alpha-gal syndrome, experts emphasize that when you are in areas where the risk of tick bites is high, you should wear protective clothing, use tick repellent sprays and carefully check every part of your body. It is important for people who have been bitten by a tick to consult a health institution for medical follow-up and to monitor their symptoms.

As the disease becomes more widespread, researchers continue to work to develop an effective treatment or vaccine against the alpha-gal molecule. Although experimental treatments have begun to be implemented in some clinics in the USA, there is no standard treatment protocol yet. Patients are recommended to limit the consumption of mammalian meat in their diet and turn to alternative protein sources.

Public health authorities state that the tick population must be controlled and public awareness must be raised to prevent the disease from spreading. Especially those who live in rural areas and engage in nature activities should be more careful about the risk of tick bites and take the necessary precautions.
