What are the Symptoms of Mixed Connective Tissue Disease?

Mixed connective tissue disease (MCTD) is a rare autoimmune disorder that features a combination of symptoms from various connective tissue diseases. Common symptoms associated with MCTD may include:

  • Raynaud’s phenomenon: Cold fingers or toes that turn white or blue in response to cold temperatures or stress, and then return to a red color when warm.
  • Swollen fingers or hands: Swelling in the fingers or hands, often with a sausage-like appearance, due to inflammation.
  • Joint pain and inflammation: Arthritis-like symptoms, such as joint pain, stiffness, and swelling, which can affect multiple joints.
  • Muscle weakness and fatigue: Generalized fatigue and muscle weakness, often accompanied by aches and stiffness.
  • Skin changes: Skin involvement may include a rash across the cheeks and bridge of the nose (resembling a butterfly), raised red patches on the skin, or thickened patches of skin on the hands.
  • Fever: Low-grade fever, usually as a result of the body’s inflammatory response.
  • Difficulty swallowing (dysphagia): Trouble swallowing due to muscle weakness in the esophagus.
  • Shortness of breath and cough: Respiratory symptoms may occur due to lung involvement, such as interstitial lung disease.
  • Heart and lung issues: Inflammation of the lining around the heart (pericarditis) or lung complications like pleuritis (inflammation of the lining of the lungs) may be present.
  • Digestive problems: Problems related to the digestive system, such as acid reflux, abdominal pain, or diarrhea.
  • Rash and photosensitivity: A skin rash that worsens with sun exposure (photosensitivity), often seen on the arms, chest, or face.
  • Headaches and seizures: Some individuals may experience headaches or, in rare cases, seizures.

It’s important to note that the symptoms and severity of MCTD can vary greatly from person to person. Additionally, the symptoms may overlap with those of other connective tissue diseases, making diagnosis challenging. If you suspect you may have MCTD or are experiencing concerning symptoms, it’s crucial to consult a healthcare professional for a thorough evaluation and appropriate management.
