Objective To evaluate the bone health of a cohort of patients with an acute Multiple Sclerosis (MS) relapse and to develop an algorithm for the management of bone health in this patient group.

Methods We recruited 53 consecutive patients from our acute relapse clinic. Bone health was assessed with Dual Energy X-ray Absorptiometry (DEXA) scanning and vitamin D levels. Statistical analyses including regression were used to define predictive variables. A review of the literature led to a proposed management protocol.

Results Pre-relapse the baseline EDSS was ≤6.5 in all subjects, and ≤4.0 in the majority. The majority of patients received corticosteroids. Half of all subjects who attended for DEXA scanning had low bone mineral density (BMD) as defined by a T-score or Z-score less than −1.0. Two were osteoporotic (T-score less than −2.5).
One third of subjects were Vitamin D deficient (25–OH–Vitamin D less than 25nmol/L).
There were no significant predictive variables for reduced BMD, including previous corticosteroid usage.

Conclusion There was a high frequency of both low BMD and Vitamin D deficiency in this cohort of relatively young and largely ambulatory patients with an acute relapse. Current tools, such as the WHO FRAX algorithm, are inadequate in assessing bone status and fracture risk in this patient group, predominantly as they are focused on older age groups. We present a simple clinical management algorithm.


Thus, among acute MS patients

  • 50% had low bone mineral density
  • 30% had < 10ng/ml of vitamin D
