Thalassemia patients often develop sensory polyneuropathy, particularly older individuals. Optimal treatment, including transfusions and deferoxamine, improves nerve function in these patients.

Area of Science:

  • Neurology
  • Hematology
  • Genetics

Background:

  • Thalassemia is a genetic blood disorder.
  • Patients may experience neurological symptoms like numbness and weakness in lower extremities.
  • The underlying cause of these symptoms is not fully understood.

Purpose of the Study:

  • To investigate the prevalence of polyneuropathy in thalassemia patients.
  • To identify factors contributing to the development of neuropathy in this population.

Main Methods:

  • Clinical and electrophysiological examinations were performed on 30 patients with thalassemia major and intermedia.
  • Findings were correlated with patient demographics, blood status, and treatment history.
  • Electrophysiological data were compared to 30 age- and sex-matched controls.

Main Results:

  • A mild sensory polyneuropathy was diagnosed in 78% of thalassemic patients.
  • Neuropathy was more severe in thalassemia intermedia.
  • Patients receiving blood transfusions and deferoxamine showed better nerve function.
  • Older age correlated with worse neuropathy, independent of sex.
  • Hemoglobin levels and splenectomy status did not impact nerve function.

Conclusions:

  • Sensory polyneuropathy is common in thalassemia patients.
  • Neuropathy risk increases with age and suboptimal treatment.
  • Effective management may mitigate neurological complications.
