Natural History is Progression Slowing

Objectives: Determine the likelihood of worsening clinical status in the near-term course of progressive MS and evaluate the predictive validity of our diagnostic impression of progressive forms of MS.
Methods: Retrospective review of charts from 175 patients seen between 2000 and 2007 who were diagnosed with either primary or secondary progressive multiple sclerosis. Data extracted included demographic factors, neurological examination findings to determine EDSS, timed 25 foot walk (T25FW) when available, duration of symptoms, clinical course as documented on initial visit, and history of disease-modifying agent (DMA) use. Significant change in EDSS was defined as a change of one point or more from initial to final clinical evaluation. Significant change in T25FW was defined as a ±20% difference from baseline.
Results: Of the 175 charts reviewed, 35 patients met criteria and had sufficient documentation to allow for EDSS abstraction. Twenty-four patients (68.6%) showed no significant change in EDSS from baseline while eleven patients (31.4%) worsened and none improved. For those patients that had T25FW data available, 6 out of 20 (30%) patients worsened while 11 (55%) showed no change. Three patients (15%) improved.
Conclusion: In this observational study at a tertiary care MS center, patients classified as progressive MS did not progress as often, or as rapidly, as previous studies have suggested. Greater than two-thirds of patients in this cohort, did not increase 1 step on the EDSS.
Highlights 
•68.6% Of progressive patients showed no significant change in EDSS from baseline.
•31.4% Of progressive patients worsened.
•For those patients that had T25FW data available, 30% worsened while 55% showed no change.
Conclusions say it all, as MSers getting better care than yesteryear
