Abstract

A 2-year-old girl presented with gonadotrophin-independent precocious puberty due to ovarian follicles. Central precocious puberty was excluded by several GnRH-tests and overnight LH sampling. There were no signs of McCune-Albright syndrome. An ovarian tumour was excluded by laparotomy and biopsies. Abdominal sonography demonstrated follicles occurring mostly in the left, sometimes in the right, ovary. Immunoglobulin G (IgG) purified from the patient's serum was capable of stimulating DNA synthesis in granulosa cells of rat ovarian segments kept in organ culture. Since FSH had a similar in-vitro action it is hypothesized that this patient's IgG mimics the action of FSH.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
