Summary
This summary is machine-generated.

A multiple sclerosis patient on interferon-β developed blurry vision and high blood pressure. Further tests revealed hypertensive retinopathy and elevated liver enzymes, suggesting treatment side effects.

Area of Science:

  • Neurology
  • Immunology
  • Ophthalmology

Background:

  • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
  • Interferon-beta (IFN-β) is a common disease-modifying therapy for relapsing MS.
  • Treatment monitoring is crucial to identify potential adverse effects.

Purpose of the Study:

  • To report a case of blurry vision in a multiple sclerosis patient on interferon-β therapy.
  • To investigate the potential causes of visual disturbances and other symptoms.
  • To evaluate the safety profile of interferon-β in long-term MS management.

Main Methods:

  • Case report of a 36-year-old male with relapsing multiple sclerosis.
  • Clinical presentation including blurry vision and severe hypertension.
  • Diagnostic workup involving MRI, fundoscopy, and laboratory tests (liver enzymes, urine albumin-to-creatinine ratio, lipid profile, CSF analysis).

Main Results:

  • The patient presented with blurry vision, significantly elevated blood pressure (214/122 mm Hg), and hypertensive retinopathy.
  • Laboratory findings showed elevated liver enzymes, microalbuminuria, and hyperlipidemia, consistent with interferon-β side effects.
  • Cerebrospinal fluid analysis was positive for oligoclonal bands, confirming MS activity, but negative for infections.

Conclusions:

  • Blurry vision in this MS patient was attributed to interferon-β treatment-induced hypertensive retinopathy and elevated liver enzymes.
  • Close monitoring for adverse effects, including hypertension and liver function, is essential during interferon-β therapy for multiple sclerosis.
  • A wait-and-see approach was adopted, managing hypertension without steroids or antimicrobials.
