Neuron-specific enolase (NSE) levels decrease in sclerotic skin lesions after UVA1 phototherapy. This reduction in NSE correlates with improved skin texture, suggesting NSE

Area of Science:

  • Dermatology
  • Immunology
  • Neurology

Background:

  • Elevated neuron-specific enolase (NSE) levels are linked to autoimmune rheumatic disorders like systemic sclerosis (SSc).
  • Serum NSE correlates with disease activity and skin score in systemic sclerosis.
  • UVA1 phototherapy is a treatment for systemic sclerosis, but its neuromodulatory effects are not fully understood.

Purpose of the Study:

  • To investigate the neuromodulatory effects of UVA1 phototherapy on acrosclerosis.
  • To assess changes in dermal neuron-specific enolase (NSE) expression following UVA1 treatment.
  • To explore the potential role of NSE in sclerotic skin lesions and its utility as a diagnostic marker.

Main Methods:

  • Punch skin biopsies were obtained from four patients with acrosclerosis before and after UVA1 phototherapy.

  • Immunohistochemical analysis was performed to detect NSE, S100, and neurofilament expression.
  • Changes in marker expression were correlated with clinical improvements in skin sclerosis.

    • Main Results:

    • UVA1 phototherapy induced a significant decrease in dermal NSE expression in sclerotic skin lesions.
    • No significant alteration was observed in neurofilament-positive cells.
    • A reduction in dermal NSE levels correlated with a softening of the sclerotic skin lesions.

    Conclusions:

    • UVA1 phototherapy reduces dermal neuron-specific enolase (NSE) levels in acrosclerosis.
    • The decrease in NSE correlates with clinical improvement, suggesting a role for NSE in sclerotic skin.
    • NSE may serve as a potential diagnostic marker for SSc-associated acrosclerotic skin.
