[Familial and nonfamilial forms of arterial hypertension]

Area of Science:

• Cardiology
• Nephrology
• Genetics

Background:

• Essential hypertension presents with diverse clinical and etiological forms, including familial (FH) and non-familial (NFH) hypertension.
• Understanding the underlying physiological differences between these forms is crucial for effective management.

Purpose of the Study:

• To investigate the distinctions in sodium-lithium countertransport and calcium-activated adenosine triphosphatase (Ca2+ ATPase) activity between FH and NFH patients with essential hypertension.
• To compare the efficacy of plasma filtration, hemosorption, and surgical interventions in managing arterial pressure in FH versus NFH individuals.

Main Methods:

• Comparative analysis of Na-Li countertransport and Ca2+ ATPase activity in blood samples from FH and NFH patients.
• Evaluation of arterial pressure reduction following plasma filtration and hemosorption therapies.
• Assessment of surgical treatment outcomes in patients with symptomatic arterial hypertension stratified by FH and NFH status.

Main Results:

• Significantly increased Na-Li countertransport was observed in FH patients compared to NFH patients.
• Conversely, Ca2+ ATPase-mediated velocity was lower in FH subjects than in NFH subjects.
• Plasma filtration and hemosorption demonstrated greater effectiveness in reducing arterial pressure in NFH patients.
• Surgical treatment for symptomatic arterial hypertension yielded more successful arterial pressure reduction in NFH individuals.

Conclusions:

• Distinct cellular transport mechanisms (Na-Li countertransport and Ca2+ ATPase activity) differentiate familial and non-familial hypertension.
• Non-familial hypertension patients exhibit a more favorable response to interventions like plasma filtration, hemosorption, and surgical treatment.
• These findings suggest different pathophysiological pathways and therapeutic sensitivities between FH and NFH essential hypertension.
