Lung Function in Women with Idiopathic Central Precocious Puberty: A Pilot Study
Hormone Research in Paediatrics
|January 24, 2017
Summary
Women with idiopathic central precocious puberty (ICPP) treated with gonadotropin-releasing hormone agonist (GnRHa) exhibit reduced lung function. This suggests potential long-term respiratory health implications requiring further investigation into hormonal influences.
Area of Science:
- Endocrinology
- Pulmonology
- Pediatric Endocrinology
Background:
- Early menarche is linked to diminished lung function in women.
- Idiopathic central precocious puberty (ICPP) involves early puberty onset.
- GnRH agonist (GnRHa) treatment is used for ICPP.
Purpose of the Study:
- To assess lung function in women with a history of ICPP treated with GnRHa.
- To compare lung function between ICPP survivors and healthy controls.
Main Methods:
- A cohort of 23 women with ICPP and 23 age-matched controls were evaluated.
- Methods included questionnaires, spirometry (pre- and post-bronchodilator), impulse oscillometry, and fractional exhaled nitric oxide (FeNO) measurement.
- Lung function parameters such as FEV1, PEF, MMEF, and airway resistance were assessed.
Main Results:
- Women with ICPP demonstrated significantly lower lung function (FEV1, PEF, MMEF) compared to controls.
- Fractional exhaled nitric oxide (FeNO) was also significantly lower in the ICPP group.
- Negative correlations were found between lung function parameters and indicators of puberty onset (hysterometry, age at diagnosis).
Conclusions:
- Women with a history of ICPP treated with GnRHa may experience persistent deficits in lung function.
- The findings highlight the need to consider the interplay between sex hormones and airway development in precocious puberty.
- Further research is warranted to elucidate the long-term respiratory effects of ICPP and its treatment.

01:27Signs of Puberty
1.8K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

751
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

01:47Lung Capacity
56.8K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

2.0K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
