Giant cell arteritis
Dr.
Lin: Hello! In this moment when healthcare resources are scarce and rare diseases are often overlooked, I am very happy to find a channel to ask some questions.
I sincerely hope you can answer my question.
Why is the incidence of Takayasu's arteritis, which is 2.6 per million, not classified as a rare disease? Because it is not classified as a rare disease, when complications such as stroke occur, we cannot apply for a disability certificate under rare disease criteria.
We really need your help! Thank you for taking the time to respond to me amidst your busy schedule! I really want to keep living.

Dr. Lin Sixie reply Rare Disease
I sincerely apologize, as I am also unclear about the criteria for including rare diseases.
I empathize with your situation.
It is classified as an autoimmune disease.
Generally speaking, with proper treatment, the prognosis is quite good.
However, I believe that in the event of a stroke complication, depending on the degree of visual impairment, one should still be able to apply for a disability certificate.
Regular follow-ups and maintaining a positive outlook are still key to a bright future.

More Info
Takayasu arteritis (TA) is a rare form of large vessel vasculitis that primarily affects the aorta and its major branches. It is characterized by inflammation of the blood vessels, which can lead to significant complications, including hypertension, ischemia, and even stroke. The incidence of Takayasu arteritis is reported to be approximately 2.6 cases per million people, which indeed qualifies it as a rare disease according to many health organizations. However, the classification of diseases as "rare" can vary by region and the specific criteria used by health authorities.
One of the challenges in recognizing Takayasu arteritis as a rare disease lies in the criteria used to define "rare." In the United States, for example, the Orphan Drug Act defines a rare disease as one that affects fewer than 200,000 individuals. While Takayasu arteritis may have a low incidence, it does not meet the threshold for being classified as an orphan disease under this definition. This can lead to difficulties in accessing specific resources, funding, and support for patients suffering from this condition.
Moreover, the lack of awareness and understanding of Takayasu arteritis among healthcare providers can contribute to its underdiagnosis and under-treatment. Many patients may experience a delay in diagnosis due to the nonspecific nature of the initial symptoms, which can include fatigue, fever, weight loss, and joint pain. This delay can lead to more severe complications, such as stroke, which you mentioned in your question. The absence of a clear classification as a rare disease can hinder patients' ability to apply for disability benefits or special healthcare programs designed for those with rare conditions.
In terms of treatment, Takayasu arteritis is typically managed with corticosteroids and immunosuppressive agents to control inflammation and prevent complications. Early diagnosis and treatment are crucial for improving outcomes and reducing the risk of serious complications, including vascular damage and stroke. Regular follow-up with healthcare providers is essential to monitor disease activity and adjust treatment as necessary.
For patients experiencing complications such as stroke, it is important to work closely with a neurologist and a vascular specialist. They can provide comprehensive care and help manage any neurological deficits that may arise. Additionally, maintaining a positive outlook and engaging in supportive care can significantly impact the quality of life for individuals living with this condition.
In conclusion, while Takayasu arteritis is classified as a rare disease based on its incidence, the challenges associated with its recognition and management highlight the need for increased awareness and resources. Patients and healthcare providers must advocate for better recognition of this condition to ensure that those affected receive the appropriate care and support. If you or someone you know is facing difficulties related to Takayasu arteritis, it is crucial to seek out specialists who are knowledgeable about the disease and can provide the necessary guidance and treatment options.
