摘要
目的探讨高泌乳素血症妇女免疫功能状态及下丘脑-垂体-肾上腺(H-P-A)轴功能的改变。方法检测高泌乳素血症妇女34例(病例组)和健康育龄妇女20例(对照组)外周血CD4+T、CD8+T淋巴细胞、抗心磷脂抗体和白细胞介素-2(IL-2)水平,皮质醇(Cs)和肾上腺皮质激素释放激素(ACTH)水平。结果(1)外周血CD4+T病例组为(42.17±6.28)%,明显低于对照组的(47.07±4.98)%(P<0.01);CD4+T/CD8+T比值病例组为(1.81±0.47),明显低于对照组(2.07±0.39)(P<0.05)。(2)抗心磷脂抗体IgG阳性率病例组(32.35%)明显高于对照组(5%)(P<0.05)。(3)IL-2水平病例组为(145.33±100)nmol/L,与对照组(89.33±40.67)mmol/L比较显著升高(P<0.05)。(4)8AM和4PM的Cs水平病例组分别为(588.61±226.61)、(348.53±179.02)nmol/L,ACTH分别为(6.31±1.85)、(6.28±3.27)pmol/L。其中病例组8AM的ACTH水平降低,4PM的ACTH、Cs水平升高,与对照组分别为(7.28±0.75)、(3.85±0.57)pmol/L,(261.70±64.11)nmol/L比较,均有显著性差异(P<0.01,P<0.05,P<0.01);病例组ACTH分泌峰值不明显,节律异常。(5)对照组IL-2与ACTH(8AM、4PM)水平均呈正相关(r=0.609,P=0.004;r=0.499,P=0.047);病例组降低的ACTH(8AM)与升高的泌乳素(PRL)水平呈负相关(r=-0.393,P=0.022)。结论高泌乳素血症患者机体内存在免疫系统机能异常状态,其H-P-A轴中Cs、ACTH分泌水平及节律紊乱。PRL可能对内分泌激素、细胞因子及神经递质发挥多重作用。
Objective: To investigate the immune function and the function of hypothalamic-pituitary-adrenal (H-P-A) axis in the condition of hyperprolactinemia. Methods: The levels of CD4^+ T, CD8^+ T, interleukin (IL)-2, cortisol, adrenocorticotropin and the anticardiolipin antibody were measured in thirty-four hyperprolactinemic women. Twenty normal fertile women were taken as control. Results: (1) The percentage of CD4^+T lymphocyte cell was significantly (P〈0.01) reduced in hyperprolactinemic women [(42.17 ±6.28)%] than that in control group [(47.07 ± 4.98)%]. The ratio of CD4^+ T/CD8^+T in hyperprolactinemic women (1.81±0.47) was significantly (P〈0. 05) lower than control group (2.07±0.39). (2) The positive rate of anticardiolipin antibody (IgG) in hyperprolactinemic women (32.35%) was significantly (P〈0.05)higher than that of control group (5%). (3) Serum level of IL-2 was significantly (P〈0.05) higher in hyperprolactinemic women [(2.18±1.5)ng/ml] than that in control group [(1.34 ± 0. 61) ng/ml]. (4) In hyperprolactinemic women, the levels of cortisol (8 : 00AM and 4PM) were (588. 16±226.61 and 348. 53±179.02)nmol/ml and the levels of ACTH (8:00AM and 4PM) were (28. 70±8. 93,28.53±14.86)pg/ml. There were significantly higher cortisol and ACTH levels at 4:00PM (P〈0.05 and P〈0.01, respectively) and lower ACTH level at 8:00AM (P〈0. 01) compared to controls [(261.70±64.11) nmol/ml, (17.49±2.60) pg/ml and (33. 70±3.40) pg/ml, respectively]. The abnormal diurnal rhythm of cortisol and ACTH secretion was observed. There was no normal ACTH peak phase at 8:00AM. (5) The levels of IL-2 in control correlated positively with the levels of ACTH both at 8:00AM and 4:00PM. In hyperprolactinemic women, the lower level of ACTH (8:00AM) correlated negatively with the higher level of prolactin. Conclusions: The immune system is abnormal in the women with hyperprolactinemia, and the levels and diurnal rhythm of cortisol and ACTH in H-P-A axis are disturbed. Prolactin may play various roles such as a cytokine, an endocrine hormone and a neurotransmitter in the regulation of network balance.
