Mixed connective tissue disease (MCTD) is a rare autoimmune disorder that often shows overlapping symptoms from three different connective tissue disorders, including systemic lupus erythematosus (SLE), scleroderma, and polymyositis. Some people with MCTD may also have rheumatoid arthritis and Sjogren’s Syndrome. MCTD often affects women under the age of 30 but can also affect people at any age. Signs and symptoms vary but may include Raynaud's phenomenon, arthritis (usually pain in the joints in the hands or feet), abnormalities of the heart, lung and skin, kidney disease, muscle weakness, and esophageal dysfunction. The cause of MCTD is currently unknown. Treatment may include medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immune-suppressing medications (such
People with MCTD may have symptoms that overlap with SLE, scleroderma, polymyositis, Sjogren’s Syndrome, or rheumatoid arthritis.
A condition called Raynaud's phenomenon sometimes occurs months or years before other symptoms of MCTD develop. Most people with MCTD have pain in multiple joints, and/or inflammation of joints (arthritis). Muscle weakness, fevers, and fatigue are also common.
Other signs and symptoms may include:
- Accumulation of fluid in the tissue of the hands that causes puffiness and swelling (edema) of one or more fingers
- Skin findings including lupus-like rashes (including reddish brown patches), reddish patches over the knuckles, violet coloring of the eyelids, loss of hair (alopecia), and dilation of small blood vessels around the fingernails (periungual telangiectasia)
- Dysfunction of the esophagus (hypomotility) causing difficulty swallowing
- Abnormalities in lung function which may lead to breathing difficulties, and/or pulmonary hypertension
- Heart involvement (less common in MCTD than lung problems) including pericarditis, myocarditis, and aortic insufficiency
- Kidney disease
- Neurologic abnormalities (in about 10% of people with MCTD) such as blood vessel narrowing causing "vascular" headaches; a mild form of meningitis; seizures; blockage of a cerebral vessel (cerebral thrombosis) or bleeding; and/or various sensory disturbances in multiple areas of the body (multiple peripheral neuropathies)
- Anemia (decreased hemoglobin and red blood cells) and leukopenia (decreased white blood cells) in 30 to 40% of cases
- Lymphadenopathy, enlargement of the spleen (splenomegaly), enlargement of the liver (hepatomegaly), and/or intestinal involvement in some cases

METHODS OF HEALING
FROM MEGHAN -
- Healthy eating (cooking at home, meal prepping meals and snacks, restricting or reducing the foods that cause the most inflammation, including gluten, dairy, and sugar)
- Exercise (only workouts that increase energy as opposed to leaving you feeling drained or fatigued, such as swimming, hiking, and yoga)
- Sleep (this is so much more crucial than I ever thought - at least 7-8 hours of sleep each night)
- Stress management (with exercise, socializing, reading, meditating, reflective yoga, and prayer)
- Supplements (such as Vitamin D3/K2, omega 3 fatty acids, vitamin c, zinc, and magnesium)
- Take prescribed medication regularly (I have been on Hydroxychloroquine (plaquenil) for over 10 years and may not be able to take it much longer due to the side effects that can occur in the eye. I am unsure about taking the other medications prescribed for MCTD, such as methotrexate. I am working with my rheumatologist to get to a place where I can decrease and then eventually stop taking plaquenil and manage MCTD with a healthy lifestyle. I think it is very important to work with your rheumatologist before stopping any prescribed medications as these medications may be preventing your immune system from causing more damage to your body, such as kidney failure.)
