Diabetes drug may prevent or delay development of polycystic ovary syndrome

30.06.2011
PCOS is most common cause of infertility in women

A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that early, prolonged treatment with the diabetes drug metformin may prevent or delay the development of polycystic ovary syndrome (PCOS) in adolescence.

PCOS affects 7 to 10 percent of women of childbearing age and is the most common cause of infertility, affecting an estimated 5 to 6 million women in the United States, according to The Hormone Foundation.

"PCOS often presents in adolescence, with irregular menstrual cycles, acne, or too much body hair," said the study's senior author, Lourdes Ibáñez, MD, PhD, professor of pediatrics at the University of Barcelona in Spain and lead author of the study. "But we believe the critical years for PCOS development may be during childhood and puberty when excessive amounts of fat are stored. That excessive weight gain overexposes the ovaries to insulin, causing them to stop ovulating and start releasing male hormones, resulting in PCOS."

In this study of 38 girls with low birth-weight and early puberty, researchers compared the efficacy of early versus late metformin treatment to prevent adolescent PCOS. A group of 19 8-year-old girls were treated with daily doses of metformin for four years. A second group of 19 girls waited five years before they began receiving daily doses of metformin at age 13 and then continued treatment for only one year. They found that early metformin therapy prevented or delayed the development of hirsutism, androgen excess and PCOS more effectively than late metformin treatment.

"Metformin, when given across the potentially critical window of puberty, may have the capacity to reprogram metabolism toward less abdominal and liver fat," Ibáñez concluded. "In the years ahead, the focus of attention should shift from late treatment of PCOS and its complications, toward the early and large-scale prevention of PCOS, with measures such as diet, exercise and metformin in young girls."

Other researchers working on the study include: Abel Lopez-Bermejo of Dr. Josep Trueta Hospital and Girona Institute for Biomedical Research in Spain; Marta Diaz of the University of Barcelona in Spain; Maria Marcos of Hospital de Terrassa in Spain; and Francis de Zegher of the University of Leuven in Belgium.

The article, "Early Metformin Therapy (Age 8-12yr) in Girls with Precocious Pubarche to Reduce Hirsutism, Androgen Excess and Oligomenorrhea in Adolescence," appears in the August 2011 issue of JCEM.

Founded in 1916, The Endocrine Society is the world's oldest, largest and most active organization devoted to research on hormones and the clinical practice of endocrinology. Today, The Endocrine Society's membership consists of over 14,000 scientists, physicians, educators, nurses and students in more than 100 countries. Society members represent all basic, applied and clinical interests in endocrinology. The Endocrine Society is based in Chevy Chase, Maryland.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
