Familial hyperaldosteronism: an European Reference Network on Rare Endocrine Conditions clinical practice guideline

Area of Science:

• Endocrinology
• Genetics
• Rare Diseases

Background:

• Familial hyperaldosteronism is a rare endocrine condition.
• Existing guidelines for primary aldosteronism may not fully address familial forms.
• Expert consensus is needed for managing these rare genetic disorders.

Purpose of the Study:

• To establish a clinical practice guideline for the diagnosis and management of familial hyperaldosteronism.
• To provide recommendations for screening, genetic testing, and treatment.
• To address the specific needs of patients with genetically confirmed familial hyperaldosteronism.

Main Methods:

• A systematic literature search was conducted by a panel of 10 experts.
• Recommendations were primarily based on expert opinion and small patient series due to the rarity of the condition.
• The guideline development involved specialists in primary aldosteronism, endocrine hypertension, pediatric endocrinology, and cardiology.

Main Results:

• The guideline outlines the genetics and molecular pathophysiology of familial hyperaldosteronism subtypes.
• It specifies patient populations to be screened and appropriate screening methodologies.
• Diagnostic and treatment strategies for genetically confirmed cases are presented.

Conclusions:

• This guideline provides a framework for managing genetically proven familial hyperaldosteronism.
• It emphasizes the importance of genetic confirmation for applying these specific recommendations.
• The guideline aims to improve the care of patients with rare endocrine conditions.
