Problem:
Uterine leiomyomata are the most common reproductive tumor in women, and their cause is not known.
Methods Of Study:
Plasma samples from 155 women (74 with and 81 without ultrasound-confirmed leiomyoma) from a new study of leiomyoma risk factors in the Detroit, Michigan area, were examined for any cross-sectional associations between commonly examined cytokines and leiomyoma presence.
Results:
Associations varied by season of sample collection defined a priori as winter (December-February) and non-winter seasons. In the winter months, interleukin (IL)13 and IL17 were positively and IP10 was inversely associated with having a leiomyoma. In the non-winter samples, VEGF, G-CSF, and IP10 were positively associated and Monocyte chemotactic protein-1, IL13, and IL17 were inversely associated with having a leiomyoma. Associations were not changed by adjustment for age or BMI.
Conclusions:
These data suggest that new insight into leiomyoma formation may be acquired through investigation of the immune system.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
