Background:
The SARS-CoV-2 coronavirus gains entry to target cells via the angiotensin-converting enzyme 2 (ACE2) receptor present on cells in blood vessels, lungs, heart, intestines, and kidneys. Renin-Angiotensin System (RAS) overactivity has also been described in metabolic syndrome, type 2 diabetes (T2D) and obesity, conditions shared by women with polycystic ovary syndrome (PCOS) We hypothesized that RAS overactivity may be present in PCOS.
Methods:
We determined plasma levels of RAS-related proteins in a cohort of age matched control women (n = 97) and women with PCOS (n = 146). Plasma levels of RAS-related proteins (ACE2, Renin and Angiotensinogen (AGT)) were determined by Slow Off-rate Modified Aptamer (SOMA)-scan plasma protein measurement.
Results:
PCOS women had a higher BMI (p < 0.001), systolic (p < 0.0001) and diastolic (p < 0.05) blood pressure, waist circumference (p < 0.0001), testosterone (p < 0.0001), free androgen index (p < 0.0001) and CRP (p < 0.0001). Renin was elevated in PCOS (p < 0.05) and angiotensinogen was lower in PCOS (p < 0.05), indicating overactivity of the RAS system in PCOS. ACE2 levels were lower in PCOS (p < 0.05), suggesting that PCOS women are at risk for development of hypertension.
Conclusion:
RAS proteins levels differed between PCOS and control women, suggesting that the insulin resistance inherent in PCOS may predispose these women to more severe COVID-19 infection.
Insights
Polycystic ovary syndrome (PCOS) is linked to Renin-Angiotensin System (RAS) overactivity, with altered RAS protein levels observed in women with PCOS. This may increase their risk for severe COVID-19 due to insulin resistance.
Area of Science:
- Endocrinology
- Cardiovascular Science
- Reproductive Medicine
Background:
- Polycystic Ovary Syndrome (PCOS) shares metabolic and cardiovascular risk factors with conditions linked to Renin-Angiotensin System (RAS) overactivity.
- SARS-CoV-2 utilizes the ACE2 receptor for cell entry, a component of the RAS.
- RAS overactivity is implicated in metabolic syndrome, type 2 diabetes (T2D), and obesity.
Purpose of the Study:
- To investigate potential Renin-Angiotensin System (RAS) overactivity in women with Polycystic Ovary Syndrome (PCOS).
- To compare plasma levels of key RAS-related proteins between women with and without PCOS.
Main Methods:
- Plasma levels of Angiotensin-Converting Enzyme 2 (ACE2), Renin, and Angiotensinogen (AGT) were measured using SOMA-scan technology.
- A cohort of 146 women with PCOS and 97 age-matched control women were analyzed.
- Clinical and biochemical parameters including BMI, blood pressure, and hormone levels were assessed.
Main Results:
- Women with PCOS exhibited higher BMI, blood pressure, waist circumference, testosterone, and CRP levels.
- Elevated Renin and lower Angiotensinogen levels in PCOS women indicate Renin-Angiotensin System (RAS) overactivity.
- Lower ACE2 levels in PCOS women suggest an increased risk for hypertension development.
Conclusions:
- Plasma levels of RAS proteins differ significantly between women with and without PCOS.
- Insulin resistance associated with PCOS may predispose women to more severe COVID-19 outcomes.
- Findings suggest a potential link between PCOS, RAS dysregulation, and infectious disease susceptibility.
