Study Notes
Patient Presentation
- A 27-year-old woman diagnosed with vitiligo experiences progressive fatigue and weight loss despite maintaining a good appetite.
- Clinical examination reveals hypertension (blood pressure: 170/110 mmHg) and tachycardia (pulse: 110/min).
- Additional symptoms include diaphoresis, brisk reflexes, and bilateral exophthalmos.
Key Medical Considerations
- Common triggers for hyperthyroid symptoms include childbirth, infection, steroid withdrawal, and trauma to the thyroid gland.
- Thyroid hormones notably increase heart rate and contractility while decreasing systemic vascular resistance, a key hallmark of Graves' disease.
Diagnostic Imaging
- Computed tomography (CT) scan or magnetic resonance imaging (MRI) of the orbits may be indicated to evaluate the condition, especially if T4 levels are normal.
- In cases of hyperthyroidism, a T3 level assessment might also provide helpful insights into thyroid function.
Laboratory Findings
- Normocytic anemia may be present in addition to low-normal levels of leukocytes and platelets.
- While not routinely performed, a biopsy would show lymphocytic infiltrates and follicular hypertrophy, indicative of autoimmune involvement.
Clinical Management
- Discontinuation of any current medication is advised if signs of infection are detected, followed by obtaining a complete blood count (CBC) with differential.
- Post-ablation of thyroid tissue, patients often transition to hypothyroidism 3-6 months later and will require lifelong thyroid hormone replacement therapy.
- Note that the destruction of thyroid tissue can initially worsen symptoms due to a transient release of thyroid hormones.
Maternal-Fetal Considerations
- Anti-TSH receptor antibodies can cross the placenta, potentially leading to fetal hyperthyroidism, necessitating careful monitoring in pregnant patients with Graves' disease.
