Rheumatoid arthritis (RA) is a chronic inflammatory condition that primarily affects the joints but can also cause systemic symptoms, including fevers. While joint pain, stiffness, and swelling are the hallmark signs of RA, many people with the condition also experience unexplained fevers. In this article, we’ll explore the causes, symptoms, and treatment options for RA fevers, offering insights on how this common but often overlooked symptom can impact overall health.
What Causes Fevers in Rheumatoid Arthritis?
Fevers in RA occur as a result of the body’s immune system attacking its own tissues. RA is classified as an autoimmune disease, where the immune system mistakenly identifies healthy tissues in the joints as foreign invaders, triggering an inflammatory response. This inflammatory response can extend beyond the joints, affecting other parts of the body and leading to systemic symptoms, including fevers.
Several factors contribute to fevers in RA, including:
- Inflammation: The chronic inflammation that characterizes RA can lead to the release of various cytokines, such as interleukins and tumor necrosis factor (TNF). These molecules can increase body temperature, causing low-grade fevers.
- Infections: People with RA, especially those taking immunosuppressive medications like methotrexate or biologics, are at a higher risk for infections. Infections can lead to fever, and distinguishing between a fever caused by RA inflammation and one caused by an infection can be challenging.
- Medications: Certain medications used to manage RA, such as disease-modifying antirheumatic drugs (DMARDs), can cause side effects like fever. These drug-induced fevers are usually mild and resolve when the medication is adjusted or stopped.
Symptoms of Rheumatoid Arthritis Fevers
The fever associated with rheumatoid arthritis is typically low-grade, meaning it usually ranges from 99°F to 100.4°F (37.2°C to 38°C). However, in some cases, the fever may be higher. The fever is often accompanied by other systemic symptoms, which may include:
- Fatigue: One of the most common symptoms associated with RA fevers is extreme fatigue. The body is expending energy dealing with inflammation, which can leave a person feeling constantly drained.
- Joint pain and stiffness: RA is known for causing pain, stiffness, and swelling in the joints, and when fevers occur, these symptoms may worsen. Morning stiffness, lasting for more than 30 minutes, is common.
- Night sweats: People with RA fever may experience excessive sweating, particularly at night. This is another systemic symptom that can affect sleep quality.
- Loss of appetite: Fever, combined with inflammation, often results in a decreased appetite. Some people with RA report losing weight due to this combination of symptoms.
- Chills: Chills may accompany fever in RA, making it feel like the person is alternating between feeling cold and hot.
Diagnosing Fevers in Rheumatoid Arthritis
Since fever is a common symptom in various conditions, it’s essential to diagnose the underlying cause of the fever. In RA, the fever typically comes along with other telltale symptoms like joint pain and inflammation, which help differentiate it from other potential causes. However, due to the overlap with infections and side effects of medications, diagnosis often requires careful evaluation by a healthcare professional.
Diagnosis may include the following:
- Blood tests: Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies are common biomarkers used to diagnose RA. Elevated inflammatory markers like ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein) are also typical in people with RA fevers.
- Imaging: X-rays or ultrasound scans can help determine the extent of joint damage in RA and identify any complications that might contribute to systemic symptoms.
- Infection screening: A physician may also conduct tests to rule out infections that could be causing the fever, such as blood cultures or urinalysis.
Treatment of Fevers in Rheumatoid Arthritis
Treating fevers in RA involves managing the underlying disease as well as addressing any potential infections or medication-related side effects. Common approaches include:
1. Disease-Modifying Anti-Rheumatic Drugs (DMARDs)
The primary treatment for RA involves DMARDs, which help slow down the disease’s progression and reduce inflammation. By controlling the inflammation, DMARDs may help reduce the occurrence of fevers. Common DMARDs include:
- Methotrexate: Often the first line of defense, methotrexate works by suppressing the immune system, reducing inflammation, and controlling RA symptoms.
- Biologic DMARDs: These drugs target specific parts of the immune system involved in inflammation, such as TNF-alpha inhibitors and interleukin-6 inhibitors. They are especially useful in severe cases of RA where traditional DMARDs are ineffective.
- Janus kinase inhibitors (JAK inhibitors): A newer class of medications that target specific pathways involved in RA inflammation. These are typically used when other treatments are ineffective or intolerable.
2. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
NSAIDs like ibuprofen can help alleviate pain, reduce inflammation, and bring down fever. They’re often used in conjunction with DMARDs to manage the symptoms of RA. However, long-term use of NSAIDs can lead to side effects like stomach ulcers, so they should be used cautiously.
3. Corticosteroids
Corticosteroids, such as prednisone, can quickly reduce inflammation and control fever in people with RA. They are typically used for short periods during flare-ups. However, long-term use can lead to serious side effects like osteoporosis and increased infection risk.
4. Treating Infections
If the fever is determined to be caused by an infection, appropriate antibiotics, antifungals, or antiviral medications will be prescribed. Infections must be treated promptly to prevent complications, especially in RA patients who are immunocompromised due to their medications.
Experiences with Rheumatoid Arthritis Fevers: Real-Life Stories
Living with rheumatoid arthritis is often a balancing act. For many people, fevers are just another part of the package. Here are a few experiences shared by those managing RA and its associated fevers:
Jane’s Journey: Jane, a 45-year-old woman diagnosed with RA, had struggled with low-grade fevers for several months. The fevers, accompanied by joint pain and stiffness, made it difficult to get through her daily routine. After visiting her rheumatologist, she was started on a combination of methotrexate and a biologic DMARD, which significantly reduced the frequency of her fevers. “The fevers weren’t just uncomfortablethey were debilitating,” she says. “I’m so grateful for the new medications that have helped me regain some normalcy in my life.”
Tom’s Story: Tom, 60, has lived with RA for over 10 years. His fever episodes were often confused with infections, causing delays in diagnosis. After being tested for infections, he was prescribed NSAIDs to manage inflammation and fever. “It took a while to get the medication balance right, but I’m feeling much better now,” he shares. “The fevers are still a problem from time to time, but I’ve learned how to manage them with my treatment plan.”
For those living with RA, it’s important to remember that you’re not alone. Managing the disease, including its fever-related symptoms, takes time and perseverance. But with the right treatment and support, it’s possible to regain control of your health and quality of life.
Conclusion
Rheumatoid arthritis fevers are a common but often underestimated symptom of the disease. Understanding the causes, recognizing the symptoms, and knowing how to treat the fevers can greatly improve a person’s quality of life. With effective medication management and lifestyle adjustments, many people with RA can reduce the frequency and severity of fevers, allowing them to focus on managing the other aspects of the disease. If you’re experiencing persistent fevers or other systemic symptoms with your RA, don’t hesitate to consult your doctor for guidance on the best treatment options.
