Cerebrospinal fluid oestrone in pseudotumour cerebri

Area of Science:

• Neurology
• Endocrinology
• Metabolic Disorders

Background:

• Pseudotumour cerebri (idiopathic intracranial hypertension) is a condition affecting young, often obese, women.
• Cerebrospinal fluid (CSF) oestrone levels in these patients are not well-characterized.
• Elevated intracranial pressure in pseudotumour cerebri requires effective management strategies.

Purpose of the Study:

• To investigate the concentration of oestrone in the CSF of obese young women diagnosed with pseudotumour cerebri.
• To evaluate the clinical efficacy of a low-calorie diet and dexamethasone treatment in this patient group.

Main Methods:

• CSF samples were collected from obese young women with pseudotumour cerebri and compared to normal subjects.
• Oestrone concentration in CSF was measured.
• Patients with pseudotumour cerebri, elevated CSF oestrone, and low CSF protein (<0.2 g/l) received an 800 calorie/day diet and dexamethasone 2 mg/day.

Main Results:

• CSF oestrone concentrations were significantly higher than predicted and in normal subjects.
• All women with pseudotumour cerebri, high CSF oestrone, and low CSF protein (<0.2 g/l) showed clinical improvement with the combined treatment.
• The treatment regimen included a restricted 800 calorie/day diet and 2 mg/day dexamethasone.

Conclusions:

• Elevated CSF oestrone may be a contributing factor in the pathophysiology of pseudotumour cerebri in obese young women.
• A combination of caloric restriction and dexamethasone is an effective treatment for pseudotumour cerebri in patients with high CSF oestrone and low CSF protein.
• Further research is warranted to elucidate the role of oestrone in idiopathic intracranial hypertension.
