Case Study:
Patient Profile:
- Name: Mary Johnson
- Age: 32 years
- Gender: Female
- Medical History: Generally healthy, no significant medical conditions.
Presenting Problem:
Mary Johnson visited her primary care physician complaining of irregular menstrual cycles and a milky discharge from her breasts. She had been trying to conceive with her husband for over a year without success. Her physician ordered blood tests, including hormone levels, and the results indicated significantly elevated prolactin levels (hyperprolactinemia).
Diagnostic Workup:
- Blood Tests: Mary’s serum prolactin levels were found to be consistently elevated at 90 ng/mL (normal range: 2-18 ng/mL).
- Imaging: An MRI scan of the brain was performed to rule out any pituitary tumors that might be causing the hyperprolactinemia. The MRI showed a small microadenoma in the pituitary gland.
Treatment Options:
Given Mary’s elevated prolactin levels and the presence of a pituitary microadenoma, her endocrinologist discussed various treatment options:
- Dopamine Agonists: The standard treatment for hyperprolactinemia caused by pituitary tumors is dopamine agonist therapy, such as cabergoline or bromocriptine. These drugs work by reducing prolactin secretion from the pituitary gland.
- Cholecystokinin (CCK) Therapy: Mary’s endocrinologist mentioned a novel approach involving cholecystokinin (CCK) therapy, which has shown promise in reducing prolactin levels in some preliminary studies. CCK would be administered via subcutaneous injections.
Treatment Plan:
Mary opted to participate in a clinical trial exploring the potential use of CCK as a treatment for hyperprolactinemia. Her treatment plan included:
- Baseline Assessment: A thorough assessment of Mary’s hormonal profile and pituitary function was conducted before starting treatment.
- CCK Administration: Mary received subcutaneous CCK injections three times a week for a duration of three months.
- Monitoring: Throughout the treatment period, Mary’s hormone levels were closely monitored, and any side effects or adverse reactions were documented.
Outcome:
After three months of CCK therapy, Mary’s serum prolactin levels were reevaluated. The results showed a significant reduction in prolactin levels, which had returned to the normal range (14 ng/mL). Additionally, her menstrual cycles became regular, and the milky discharge from her breasts ceased.
Discussion:
Mary’s case highlights the potential of CCK as an alternative treatment for hyperprolactinemia, especially in cases where dopamine agonists may be less effective or not well-tolerated. The use of CCK in this clinical trial demonstrated promising results, providing a potential avenue for individuals like Mary to manage their condition and improve their fertility.
