Causes of elevated ESR (Erythrocyte Sedimentation Rate)


Hello Dr.
Zhao: I am a patient with ankylosing spondylitis and am currently undergoing stable treatment with medication in the rheumatology department.
All my symptoms and indices have been well controlled, except for my ESR, which remains around 30.
I would like to ask you some questions regarding ESR: 1) Generally, if there is a spinal fracture or spondylolisthesis causing lower back pain, can it lead to an ESR elevation above 30? 2) Can tendonitis caused by sports injuries also result in an ESR elevation above 30? Thank you, doctor.

Hello: ESR refers to the erythrocyte sedimentation rate, which is a method for measuring inflammatory proteins.
However, lower back pain caused by vertebral fractures or slippage, as well as muscle and tendon inflammation due to sports injuries, typically do not result in an elevated ESR.
It is recommended to seek treatment at our Rheumatology and Immunology Department.
Thank you for your concern for your health from Changhua Hospital.

Elevated Erythrocyte Sedimentation Rate (ESR) levels can be a significant concern for patients with Ankylosing Spondylitis (AS), particularly when they are undergoing treatment and monitoring their inflammatory markers. ESR is a non-specific marker of inflammation, which means that while it can indicate the presence of inflammation in the body, it does not specify the cause or location of that inflammation.
In the context of your questions regarding ESR levels in relation to spinal conditions and sports injuries, let's break down the inquiries:
1. Impact of Spinal Fractures or Spondylolisthesis on ESR Levels:
Spinal fractures or spondylolisthesis can indeed lead to increased pain and inflammation in the lower back. However, while these conditions can cause discomfort and may lead to an inflammatory response, it is not guaranteed that they will elevate ESR levels to 30 or above. ESR levels can be influenced by various factors, including the extent of inflammation, the presence of other underlying conditions, and individual patient responses. In many cases, localized pain from such conditions may not significantly elevate systemic inflammatory markers like ESR unless there is a more widespread inflammatory process occurring.

2. Effect of Sports Injuries and Tendonitis on ESR Levels:
Similar to spinal issues, sports injuries, particularly those that result in tendonitis, can also lead to localized inflammation. However, the degree to which these injuries elevate ESR levels can vary widely among individuals. Generally, mild to moderate tendonitis may not cause a significant increase in ESR, and levels may remain within normal ranges. In more severe cases, or if there is a significant inflammatory response, it is possible for ESR to rise, but reaching levels above 30 would typically indicate a more pronounced inflammatory process.

In your case, with an ESR consistently around 30 despite stable treatment for AS, it is essential to consider that this level may reflect a chronic inflammatory state rather than an acute exacerbation. Chronic conditions like AS can lead to persistent low-grade inflammation, which may keep ESR elevated even when other symptoms are well-controlled.
It is also important to note that ESR is influenced by various factors, including age, sex, and even certain medications. For instance, some anti-inflammatory medications can lower ESR levels, while others may not have a significant effect. Therefore, it is crucial to interpret ESR levels in conjunction with clinical symptoms and other laboratory findings, such as C-reactive protein (CRP) levels, which can provide additional insight into the inflammatory status of the patient.

If you are concerned about your ESR levels, it would be advisable to discuss this with your rheumatologist. They may consider further investigations or adjustments to your treatment plan based on a comprehensive assessment of your symptoms, ESR, and other inflammatory markers. Additionally, maintaining a healthy lifestyle, including regular exercise and a balanced diet, can help manage inflammation and overall health in patients with AS.

In conclusion, while elevated ESR levels can indicate inflammation, the specific causes and implications can vary significantly among individuals, especially in chronic conditions like Ankylosing Spondylitis. Regular monitoring and open communication with your healthcare provider are key to managing your condition effectively.
