What is muscular rheumatism?
Muscular rheumatism is an inflammatory condition that results in muscle pain and stiffness, primarily in the shoulder and pelvic areas. It more commonly affects adults over 50 and can significantly impact quality of life.
Difference between muscle rheumatism and other forms of rheumatism
Unlike other rheumatic diseases, such as rheumatoid arthritis , polymyalgia rheumatica (PER) affects the muscles rather than the joints . Symptoms are also more concentrated in specific areas (especially the shoulders and hips) and are not accompanied by joint damage seen in other forms of rheumatism.
Causes of muscular rheumatism
Although the exact cause of polymyalgia rheumatica is not fully understood, researchers have identified several factors that contribute to its development. These factors include known risk factors and triggers, as well as theories about the origin of the disease.
Known risk factors and triggers
The chance of developing polymyalgia rheumatica is influenced by several factors:
- Age : Polymyalgia rheumatica primarily affects people over 50. The risk increases with age, suggesting that age-related changes in the immune system or metabolism may play a role in the development of the condition.
- Gender : Women are more likely to develop polymyalgia rheumatica than men. This difference may reflect the influence of hormonal factors or differences in immune responses between the sexes.
- Ethnicity : Polymyalgia rheumatica is more common in people of European (particularly Scandinavian) descent. This pattern suggests that genetic components play a role in susceptibility to the disease.
Theories about the origin of the disease
Researchers have developed several theories to explain the origins of polymyalgia rheumatica, pointing to the interaction between genetic and environmental factors:
- Heredity : Genetic research has shown that people with certain genetic markers have a higher risk of developing polymyalgia rheumatica. This suggests that heredity plays a significant role in susceptibility to the disease.
- External triggers : There is evidence that external factors, such as viral or bacterial infections, can trigger an inflammatory response in people genetically predisposed to polymyalgia rheumatica. These infections can activate the immune system in a way that leads to the symptoms of polymyalgia rheumatica.
- Immune system dysregulation : Some theories suggest that polymyalgia rheumatica is the result of an abnormal immune response, where the body attacks its own tissues, resulting in inflammation and its associated symptoms.
- Environmental factors : Besides infections, other environmental factors, such as exposure to certain chemicals or extreme climates, can also contribute to the development of polymyalgia rheumatica. These factors can influence both genetic predisposition and the immune response.
Symptoms and complaints of muscular rheumatism
Muscular rheumatism manifests itself in a range of symptoms and complaints that can be both general and specific to the condition. These symptoms can significantly impact not only the patient's physical well-being but also their emotional and social life. Below is a detailed explanation of these symptoms and their effects.
General symptoms
The most common symptoms of muscular rheumatism include:
- Morning stiffness : This is often the first sign of polymyalgia rheumatica, with patients noticing that their muscles are stiff and painful upon waking. This stiffness can be so severe that it significantly hinders routine morning activities, such as getting out of bed.
- Pain : The pain is diffuse and can vary in intensity, often described as a deep, aching pain that can affect both rest and activity.
- Fatigue : An overwhelming feeling of exhaustion that is disproportionate to recent activities. This fatigue is often more pronounced than one would expect from normal daily activities and does not necessarily resolve with rest.
Specific symptoms related to muscular rheumatism
In addition to the general symptoms, there are specific signs that are particularly indicative of polymyalgia rheumatica:
- Acute pain and stiffness in the shoulder and pelvic areas : These symptoms can come on suddenly and are often so severe that they restrict normal movement. The pain and stiffness may be asymmetrical, with one side of the body affected more than the other.
- Sensitivity to touch : The areas around the affected muscles may be exceptionally sensitive, making even light touch or pressure uncomfortable or painful.
Impact on daily life
The symptoms of polymyalgia rheumatica can have a significant impact on daily activities and quality of life:
- Difficulty with daily activities : Tasks that were once simple, such as putting on clothes, reaching overhead, or rising from a sitting position, can become challenging. These limitations can lead to frustration and a sense of dependency.
- Impact on personal care and hygiene : Activities such as combing hair, taking a shower, or performing personal hygiene routines can be painful and difficult, affecting the patient's autonomy and well-being.
- Social and emotional consequences : The chronic pain and disability associated with polymyalgia rheumatica can lead to social isolation, depression and anxiety, as patients may have to limit or give up their usual activities and hobbies.
Diagnosis of muscular rheumatism
Diagnosing muscular rheumatoid arthritis, a complex and often misunderstood condition, requires careful evaluation and a series of diagnostic procedures. Despite the challenges associated with diagnosing muscular rheumatoid arthritis, an accurate diagnosis is crucial for initiating effective treatment and improving patient care.
Medical tests and procedures
- Clinical presentation : The diagnostic process begins with a thorough medical history and physical examination. Doctors look for typical symptoms of polymyalgia rheumatica, such as muscle pain and stiffness in the shoulders and hips, morning stiffness, and how these symptoms affect daily activities. The patient's age and the sudden onset of symptoms can also be important clues.
-
Blood tests : Blood tests are essential for identifying signs of inflammation in the body. Two important markers are:
- Erythrocyte sedimentation rate (ESR) : An increased value may indicate the presence of an inflammatory process in the body.
- C-reactive protein (CRP) : Like ESR, an elevated CRP level is an indicator of inflammation. A significant increase supports the diagnosis of polymyalgia rheumatica.
- Imaging : Although polymyalgia rheumatica is primarily a clinical diagnosis, imaging tests such as ultrasound, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans can be used to visualize the inflammation of the tissues surrounding the joints and rule out other potential causes of the symptoms. These tests can help identify polymyalgia rheumatica-specific patterns of inflammation not seen in other conditions.
Treatment of muscular rheumatism
Treatment for muscular rheumatism focuses on reducing inflammation, pain, and stiffness to improve patients' quality of life. Treatment for this condition involves a combined approach of medication and non-drug therapies.
Medicines
- Corticosteroids : These form the basis of treatment for polymyalgia rheumatica and work by reducing inflammation, thus relieving symptoms such as pain and stiffness. Prednisone is the most commonly prescribed corticosteroid. The initial dose is often higher to quickly control symptoms, after which the dose is gradually reduced to minimize side effects.
- Painkillers : In addition to corticosteroids, painkillers such as NSAIDs (nonsteroidal anti-inflammatory drugs) or acetaminophen can be used to provide comfort and manage pain. However, the use of these medications should always be discussed with your doctor to avoid interactions and side effects.
- DMARDs and Biologic Agents : In some cases, when patients do not respond well to corticosteroids or when long-term corticosteroid use is inadvisable, disease-modifying anti-rheumatic drugs (DMARDs) or biologic agents may be considered. These medications can help modulate the immune system and reduce inflammation.
Other treatments
- Physical therapy : An essential part of treatment, physical therapy helps patients maintain muscle strength, improve flexibility, and increase overall functionality. Exercises specifically designed for patients with polymyalgia rheumatica can help manage symptoms and improve mobility.
-
Lifestyle adjustments :
- Regular exercise : Gentle, regular exercise such as walking, swimming, or yoga can help reduce muscle stiffness and improve overall physical condition. It's important to choose activities that don't put extra stress on painful areas.
- Healthy eating : A balanced diet rich in anti-inflammatory foods can help support overall health and potentially reduce the body's inflammatory response. Foods rich in omega-3 fatty acids , antioxidants, and fiber are recommended.
- Stress management : Stress can worsen the symptoms of polymyalgia rheumatica. Techniques such as mindfulness, meditation, and relaxation exercises can help manage stress and improve well-being.
