Temporal arteritis, also known as giant cell arteritis, is an inflammatory disease of the large arteries, primarily affecting the temporal and medium to large arteries. It is classified as a form of arteritis that is often associated with other systemic diseases such as polymyalgia rheumatica. Temporal arteritis primarily affects older adults, especially women, and can present with severe neurological complications, including vision loss, due to involvement of the arteries that supply the eye. Symptoms often include headaches, tenderness to palpation of the temporal region, fatigue, fever, and weight loss. Early diagnosis and treatment are important, as advanced forms can lead to serious complications.
History of the disease and interesting historical facts
Historically, temporal arteritis was first described in the late 19th century. Around 1890, Swedish physicians began observing cases in which acute headaches and visual disturbances were associated with arterial abnormalities. The scientific community began to pay attention to the nosology only in the early 20th century. Initially, the disease was associated with acute arteritis, but later it became clear that this chronic inflammation leads to acute exacerbations. An important step in the scientific understanding of temporal arteritis were studies in the 1970s and 1980s, which demonstrated a link between this disease and infectious agents.
Epidemiology
Statistics show that temporal arteritis occurs with a frequency of approximately 20 cases per 100,000 people per year. The dependence of the incidence on age is manifested starting from the age of 50, with a sharp increase in cases among people over 70. Women suffer from temporal arteritis 2-3 times more often than men, which may indicate possible hormonal and genetic factors influencing the predisposition to the disease. In addition, the frequency of occurrence of this disease varies in different populations: for example, it is observed more often among Scandinavian peoples than among the Chinese population.
Genetic predisposition to this disease
Current research suggests a genetic predisposition to temporal arteritis, particularly the involvement of certain genes, such as HLA-DRB1, which are associated with inflammatory diseases. Mutations in these genes may affect the immune response and predispose to autoimmune reactions, which may lead to the development of inflammatory processes in the arterial walls. Research also points to the possible influence of certain polymorphisms in genes associated with cytokine production, which may enhance the inflammatory process.
Risk factors for the development of this disease
Risk factors for temporal arteritis can be divided into several categories:
- Age: the incidence distribution increases with age, with the most vulnerable group being over 50 years of age.
- Gender: Women are more likely to suffer from temporal arteritis than men.
- Family history: Having relatives with autoimmune diseases increases the risk.
- Certain medical conditions: Having medical conditions such as polymyalgia rheumatica may indicate an increased risk of developing temporal arteritis.
- Environmental factors: Exposure to certain chemicals and physical factors may be associated with disease development, although the specific mechanisms are unclear.
Diagnosis of this disease
The main symptoms of temporal arteritis include:
- Intense headaches, often in the temporal region.
- Pain on palpation over the temporal artery.
- Tired from physical activity and long walks.
- Unexplained weight loss and fever.
- Visual symptoms associated with impaired blood supply to the eyes.
Laboratory tests typically include C-reactive protein and erythrocyte sedimentation rate (ESR), which are often elevated in inflammation. Radiological tests such as ultrasound or MRI may be used to visualize inflammation of the arteries. Differential diagnosis with other types of arteritis and neurological diseases is also important.
Treatment
Treatment of temporal arteritis should always be comprehensive and aimed at relieving inflammation and preventing complications. General treatment includes:
- Reduction in the intensity of symptoms.
- Prevent complications such as vision loss.
Pharmacological treatment usually begins with corticosteroids, usually prednisone, used in high doses to quickly control symptoms. Other anti-inflammatory drugs may be added to control chronic pain. In rare cases, if drugs are not effective enough, surgery may be required to correct vascular abnormalities.
List of medications used to treat this disease
The main drugs used in the treatment of temporal arteritis include:
- Prednisolone
- Methotrexate
- Azothioprine
- Tofacitinib
- Hydroxychloroquine
Disease monitoring
Regular monitoring of the patient's condition includes monitoring of blood clotting levels, assessment of inflammatory markers, and assessment of the functional state of the optic nerve. The prognosis with adequate therapy is good, but an advanced form of the disease can lead to irreversible complications, including vision loss and behavioral disorders. Complications can develop if therapy is started with a significant delay.
Age-related features of the disease
Temporal arteritis usually has its own characteristics depending on the age group. In people over 70 years of age, the disease often occurs with pronounced systemic manifestations and a higher risk of complications, including complications in vision. In patients under 70 years of age, symptoms may be less pronounced, but there is a possibility of rapid progression of the disease, which requires vigilant monitoring.
