Polymyalgia Rheumatica
Polymyalgia Rheumatica (PMR) and Giant Cell Arteritis (GCA) are two related illnesses that primarily affect people over 50 years old. PMR often causes stiffness and muscle pain in the neck, shoulders, and hips. It can also cause fever, fatigue, and unintended weight loss. GCA, on the other hand, can cause inflammation in the blood vessels in the head, neck, and other areas. Symptoms may include headaches, vision loss, and scalp tenderness. Both illnesses can be difficult to diagnose as symptoms can be non-specific and overlap with other conditions. Treatment for both illnesses may involve corticosteroids, which can help reduce inflammation and relieve symptoms. Without treatment, GCA can cause serious complications such as stroke or blindness, so early detection and treatment is essential.
Symptoms of Polymyalgia Rheumatica
What are the symptoms of Polymyalgia Rheumatica (PMR)?
Polymyalgia Rheumatica (PMR) is a disorder which causes pain and stiffness in the muscles of certain parts of the body. The common symptoms of PMR include aching and morning stiffness in the shoulders, hips, neck, arms, and thighs. Apart from this, patients may also experience fatigue, fever, weight loss, depression and insomnia.
What are the common causes of Giant Cell Arteritis (GCA)?
The common cause of Giant Cell Arteritis (GCA) is the inflammation of the arteries, mostly in the scalp and head region. The inflammation may cause the arteries to narrow or even block, which can disrupt the blood flow to some vital organs of the body like eyes and brain. The exact cause of the inflammation is still unknown, but it is believed that a genetic predisposition may increase the risk of developing GCA.
How does inflammation play a role in PMR and GCA symptoms?
Inflammation plays a significant role in both PMR and GCA symptoms. Inflammation occurs when the immune system attacks healthy tissues in the body, resulting in swelling, redness and pain. In PMR, the inflammation occurs in specific muscles groups, which causes pain and stiffness. In GCA, inflammation occurs in the walls of the arteries, which results in the blocking of blood flow, leading to vision loss, headaches and jaw pain among other symptoms.
What are the early signs of GCA?
Early signs of GCA may include symptoms such as a headache, tender scalp, blurred vision, jaw pain, fatigue, and fever. If not treated quickly, GCA may cause severe complications such as blindness, stroke, and even death. It is essential to note that some of these symptoms are not specific to GCA, and a medical professional must make a diagnosis.
What causes the severe headaches associated with GCA?
The severe headaches associated with GCA are caused by the inflammation of the arteries in the head region. The arteries in the brain supply oxygen and nutrients, and when they are inflamed, they can narrow or block, leading to insufficient blood supply, which results in headaches or even strokes. It is of utmost importance to raise awareness of GCA`s symptoms, and once diagnosed, it can be treated with steroids or immunosuppressants to manage inflammation and reduce complications.
Diagnosis of Polymyalgia Rheumatica
What are the blood tests commonly used to diagnose PMR/GCA?
The blood tests commonly used to diagnose PMR/GCA include erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels.

Temporal artery biopsy has been considered the gold standard test for diagnosing GCA, but recent studies have shown that imaging tests like ultrasound and MRI may be equally effective.

Imaging tests like ultrasound and MRI can aid in the diagnosis of PMR/GCA by showing inflammation in the affected areas, but they should not be used as the sole method of diagnosis. Source: NIAMS 4. It typically takes a few days to a week for the results of blood tests for PMR/GCA to come back. Source: Mayo Clinic 5. While there is no definitive test to rule out a diagnosis of PMR/GCA, a negative temporal artery biopsy does not necessarily mean that the patient does not have these conditions. Other tests and clinical manifestations should be taken into consideration. Source: NIAMS

Treatments of Polymyalgia Rheumatica
What medications are commonly prescribed for the management of PMR and GCA?
Corticosteroids such as prednisone are the mainstay of treatment for both PMR and GCA. Other medications that may be prescribed include methotrexate, tocilizumab, and azathioprine.
How frequently should patients undergo blood tests while on corticosteroid treatment for PMR and GCA?

Which symptoms of PMR and GCA can be managed with non-pharmacological interventions?
Patients undergoing corticosteroid treatment for PMR and GCA should have regular blood tests to monitor their blood sugar, cholesterol, and bone density. The frequency of these tests may vary depending on the patient`s individual needs and response to treatment.
Are there any alternative therapies that can be used in conjunction with conventional treatment for PMR and GCA?

How can healthcare providers monitor and manage the potential side effects of long-term corticosteroid use in patients with PMR and GCA?
Non-pharmacological interventions such as exercise, physical therapy, and rest can help manage symptoms of PMR and GCA. These interventions can improve strength, flexibility, and mobility, reduce pain and stiffness, and improve overall quality of life.
Prognosis of Polymyalgia Rheumatica
What is the typical duration of PMR and GCA?
The typical duration of PMR (polymyalgia rheumatica) ranges from six months to several years, with the average duration being around two years. GCA (giant cell arteritis) typically lasts for a few years but can continue for up to a decade.
Are patients with GCA prone to relapses?
Yes, patients with GCA are prone to relapses. According to a study published in the Journal of Rheumatology, up to 50% of patients with GCA experience relapses, often within the first two years after the initial diagnosis.
Does the severity of symptoms affect the long-term outlook for PMR and GCA?
The severity of symptoms does not necessarily affect the long-term outlook for PMR and GCA. According to a study published in the Journal of Clinical Rheumatology, patients with severe PMR symptoms tend to have a longer treatment duration but similar long-term outcomes compared to those with less severe symptoms.
What is the overall survival rate for patients with PMR and GCA?
The overall survival rate for patients with PMR and GCA is relatively high. According to a study published in the Annals of Internal Medicine, the 10-year survival rate for patients with PMR and GCA is around 70% – similar to that of the general population.
Can early diagnosis and treatment improve the prognosis for PMR and GCA?
Early diagnosis and treatment can improve the prognosis for PMR and GCA. According to the American College of Rheumatology, early treatment with glucocorticoids (steroids) can prevent serious complications and improve outcomes for both PMR and GCA. It is important for patients to seek medical attention as soon as symptoms appear and for healthcare providers to promptly diagnose and treat these conditions.
Prevention of Polymyalgia Rheumatica
What are the recommended preventative measures for Polymyalgia Rheumatica (PMR) and Giant Cell Arteritis (GCA)?
Recommended preventative measures for Polymyalgia Rheumatica (PMR) and Giant Cell Arteritis (GCA) include regular exercise, healthy eating, and not smoking. Ensuring a healthy weight, getting enough sleep, and managing stress can also help prevent these conditions. People who are over 50 and have a family history of either PMR or GCA should be more vigilant in monitoring any symptoms.
Can lifestyle changes lower the risk of developing PMR and GCA?
While lifestyle changes such as a healthy diet and exercise can help prevent the development of PMR and GCA, there is no definitive evidence to suggest that they can fully eliminate the risk. However, making these lifestyle changes can improve overall health and reduce the risk of other related conditions.
Are there any medications that can act as preventative measures for PMR and GCA?
Medications such as low-dose aspirin and statins may have a preventative effect in reducing the risk of PMR and GCA. However, more research is needed to fully understand the impact of these medications for prevention.
How effective are regular check-ups and screenings for detecting PMR and GCA before they progress?
Regular check-ups and screenings are important for detecting PMR and GCA before they progress, as early detection and treatment can significantly improve outcomes. People who are at higher risk, such as those over 50 or with a family history of these conditions, should discuss screening options with their healthcare provider.
Are there any specific dietary changes that can help prevent PMR and GCA?
While there are no specific dietary changes that can prevent PMR and GCA, a balanced and healthy diet can contribute to overall health and reduce the risk of related conditions. Eating a variety of fruits, vegetables, lean proteins, and whole grains can provide the essential nutrients needed for optimal health.
