Hyperprolactinemia: a 12-year retrospective study at gynecologic endocrinology unit, Siriraj Hospital.

BACKGROUND: Hyperprolactinemia is one of the most common endocrine disorders of the hypothalamic-pituitary axis. To date, no available data about hyperprolactinemia in Thai women has been published OBJECTIVE: To determine clinical and laboratory findings of Thai female patients with different etiology of hyperprolactinemia, as well as the response of treatment, recurrence, and pregnancy after treatment. MATERIAL AND METHOD: Medical records of 139 female patients with the diagnosis of hyperprolactinemia in Gynecologic Endocrinology Unit, Siriraj Hospital between January 1, 1999 and December 30, 2011 were retrospectively reviewed after the study protocol was approved by Siriraj Institutional Review Board. The data was analyzed to determine patient demographic data, presenting symptoms, duration of symptoms, initial serum prolactin levels, causes, imaging studies, treatment, treatment outcomes, and adverse events. RESULTS: Ninety-seven female patients with hyperprolactinemia were included in the study. Mean age at diagnosis was 31.8 +/- 7.7 years. Amenorrhea was the most common presenting symptom (49.5%) followed by galactorrhea (44.3%). Median initial serum prolactin level was 117 ng/mL (25.1-1,624 ng/mL). Pituitary adenoma is the most common cause (40.2%) followed by idiopathic hyperprolactinemia (37.1%). Microadenomas were found in 74.3% of pituitary adenoma. The median size of the tumor was 9 mm. Medical treatment was given to 79 (88.8%) patients. Bromocriptine was given to 66 patients. Mean of maximum dose of bromocriptine was 5.8 mg. Median duration of treatment was 35.8 months. Adverse events were reported in 24.2% of patients, dizziness was the most common adverse event. Median time to normalize serum prolactin level was 3.8 months. In 29 patients who desired pregnancy, eight patients got pregnant. Median time to pregnancy was 25.9 months. Patients with macroadenoma had significantly higher prolactin level than those with microadenoma (p = 0.024). Patients with galactorrhea had the shortest duration of symptom (p = 0. 010). There were no statistically significant difference in symptoms, duration of symptoms, and initial prolactin level between patients with and without pituitary adenoma. Patients with pituitary adenoma needed higher doses (p = 0.009) and longer duration of treatment (p = 0.007) than those without a tumor Normalization of prolactin level and recurrence rate was not different between the two groups (p = 0.056 and 0.374). Log rank test showed that the time to normalize and survival time of recurrence were not significantly different between patients with and without a tumor (p = 0.136 and 0.146, respectively). CONCLUSION: Amenorrhea was the most common presenting symptom in Thai hyperprolactinemic females, who attended Siriraj gynecologic endocrinology unit, followed by galactorrhea. Pituitary adenoma is the most common cause followed by idiopathic hyperprolactinemia. Patients with pituitary adenoma needed higher doses and longer duration of treatment than those without a tumor

Hormonal replacement therapy in surgical menopause with underlying endometriosis.

OBJECTIVE: To evaluate the effect of hormonal replacement therapy (HRT) regimens in surgical menopause patients with underlying endometriosis. DESIGN: Observational retrospective study. MATERIAL AND METHOD: 123 women with endometriosis after definite surgery (total abdominal hysterectomy with bilateral salpingo-oophorectomy) were followed in the Gynecologic Endocrinology and Menopause clinics. Patients were classified into 4 groups according to HRT regimens, i.e. control (no HRT, n=17), estrogen only (ERT, n=50), cyclic estrogen/progestin regimen (cyclic E/P, n=16), and continuous combined estrogen/progestin (ccE/P, n=24). 12 patients who received more than one regimen and 4 patients who received less than 6 months of HRT were excluded from the study. The information was obtained from the medical records. RESULTS: Mean age at surgery of all patients was 38.9 years old. Mean duration of HRT was 41.2 months. There was no difference in age at surgery or duration of follow-up in each group. There was 1 (2%) case of recurrent endometriosis and 3 (6%) cases of recurrent symptoms in the estrogen only group; none of them required additional surgical treatment. Malignant transformation was not found. CONCLUSIONS: Although the present series is small, it seems that HRT is safe for postmenopausal women with underlying endometriosis. Recurrence of endometriosis has rarely been a problem with HRT, especially in those who received the combination of estrogen and progestin regimens.
