Summary

Multiple sclerosis (MS) in Sardinia shows complex etiopathogenesis, with heterogeneous distribution and varying immunogenetic profiles. This highlights the need for further research into genetic and environmental factors influencing MS.

Area of Science:

  • Neurology
  • Immunology
  • Genetics

Background:

  • Multiple sclerosis (MS) is a chronic central nervous system disease impacting young adults.
  • Its etiology and pathogenesis remain incompletely understood, with evidence suggesting both genetic and environmental influences.
  • MS exhibits significant heterogeneity, necessitating studies in genetically stable populations.

Purpose of the Study:

  • To review recent findings on the epidemiological, genetic, and environmental peculiarities of Multiple Sclerosis (MS) in Sardinia.
  • To investigate the complex factors contributing to MS in a genetically homogeneous population.

Main Methods:

  • Review of epidemiological data on MS distribution in Sardinia.
  • Analysis of immunogenetic profiles and clinical phenotypes within the Sardinian population.

  • Comparison of MS characteristics between northern and southern provinces.

    • Main Results:

    • Heterogeneous distribution of MS cases observed in northern Sardinia, not solely attributable to genetic variations.
    • Distinct immunogenetic profiles and associations with other immune-mediated diseases identified.
    • Progressive changes in clinical phenotype, including age at onset, noted in Sardinian MS patients.

    Conclusions:

    • MS etiopathogenesis in Sardinia is more complex than previously assumed, even in a genetically stable population.
    • Observed variations in patient cohorts and territorial distribution underscore the intricate interplay of factors.
    • Further research is crucial to unravel the multifaceted nature of MS in this unique setting.
