Pseudoxanthoma elasticum

Area of Science:

• Genetics and rare diseases
• Connective tissue disorders
• Medical pathology

Background:

• Pseudoxanthoma elasticum (PXE) is a genetic disorder impacting connective tissue.
• It presents with multi-systemic manifestations, notably affecting skin, eyes, and the cardiovascular system.
• While skin changes are visible, ocular and cardiovascular complications pose the most severe risks to patients.

Purpose of the Study:

• To provide a comprehensive review of Pseudoxanthoma elasticum (PXE).
• To discuss current clinical and pathological findings.
• To explore recent advancements in therapeutic approaches, pathogenesis, and genetics.

Main Methods:

• Literature review of clinical and pathological findings in PXE.
• Analysis of recent research on PXE pathogenesis and genetics.
• Summary of current and emerging therapeutic strategies for PXE.

Main Results:

• PXE is characterized by progressive calcification and fragmentation of elastic fibers.
• Ocular manifestations include angioid streaks, leading to potential vision loss.
• Cardiovascular involvement can result in peripheral arterial disease and hypertension.

Conclusions:

• PXE requires a multi-disciplinary approach for management due to its systemic nature.
• Understanding the genetic basis of PXE is crucial for developing targeted therapies.
• Ongoing research into pathogenesis and therapeutics offers hope for improved patient outcomes.
