Graves' Disease

 

Welcome to PT 635 Pathophysiology of Complex Patient Problems This is a wiki created by and for the students in the School of Physical Therapy at Bellarmine University in Louisville KY. Please do not edit unless you are involved in this project, but please come back in the near future to check out new information!!

Definition/Description

Graves’ is classified as an autoimmune disease that affects the thyroid gland. It causes goiters, hyperthyroidism, ophthalmopathy, and occasionally dermopathy.(ginsberg) Graves'  disease is known for increasing the thyroid stimulating hormone raising the T4 levels which leads to hyperthyroidism symptoms.(DD) Hyperthyroidism /Graves' disease can manifest itself in multiple systems.

Prevalence

Graves’ disease is more prevalent in the Caucasian race affecting more women than men at a ratio of 4:1 and ages range from 30-60years (Hemmiki and DD). Graves’ disease accounts for 85% of all cases of hyperthyroidism. (Pathology)

Characteristics/Clinical Presentation

Goiter, Exophthalmos, tremors, tachycardia with palpitations, heat intolerances, weight loss, increased deep tendon reflexes, weakness and muscle atrophy, increased cardiac output, myasthenia gravis, thin hair, warm moist skin, sensitivity to light, dysphasia, diarrhea, amenorrhea, polyuria, and many other presentations, some of which may not be as common and more subtle. (pathology)

Associated Co-morbidities

Rhuematoid arthritis is one of the major associated autoimmune diseases but a raise in incidence for a co-morbidity of any autoimmune diseases. (Boelaert) Recommendation for futher autoimmune disease screening may be warrented with the diagnosis of Graves' disease. 

There is also an increased risk of cancer in the thyroid nodules associated with Graves' disease and further ultrasonography imaging and/or biopsy may be needed for further testing if suspected malignancy. (Ginsberg)

Diagnostic Tests/Lab Tests/Lab Values

Thyroid blood serum testsare taken A positive test results include a decreased or normal TSH levels, elevated free thyroxine t4 diagnosis of hyperthyriodism. To specify graves disease Radioiodine uptake test is used.(Ginsberg)

Thyroid stimulating Hormone Antibodies (TRAb) and thyroid peroxidase autoantibodies (TPOAb) may be found in most patients, but is not needed for specific diagnosis since most patients are diagnosed with blood serum tests and symptomology. (Fukushima)

Etiology/Causes

Has both a genetic, lack of suppressor t-cells causing increase in TSH receptor antibodies, and environmental causes which includes, but not limited to the following: stress, smoking, post pardum, and infections (Hemminki and ginsburg)

Systemic Involvement

Medical Management (current best evidence)

The current best management of Graves' disease varies upon several factors of the individual recieving it. The options include partial and full removal of thyroid gland, antithyroid drug therapy, and radioiodine therapy (franklyn).
