INTRODUCTION: Neuromyelitis optica (NMO) is an idiopathic demyelinating disorder characterized mainly by optic neuritis and myelitis, causing gradual loss of vision and deterioration of neurological function. The underlying pathogenesis mainly involves antibodies against aquaporin 4. The effectiveness of therapeutic plasma exchange (TPE) has been shown by many studies across the globe but are only a few from India. We studied ten cases of NMO retrospectively to find out the safety and efficacy of plasma exchange and to know the outcome of those patients who underwent the procedure.
MATERIALS AND METHODS: We retrospectively analyzed ten cases of NMO who underwent TPE from January 2017 to July 2021. Out of 153 patients on whom plasma exchange procedures were done during this period, ten cases of NMO were diagnosed and managed with TPE.
RESULTS: In our study, we found that 6 of our patients (60%) had a marked improvement noticed clinically with an increase in baseline power of limbs from 0–2/5 to 3–5/5. However, two patients expired after despite TPE. The other two did not show any improvement. Four of our patients started showing clinical improvement after the 2nd–3rd cycles of treatment. TPE was initiated early (within 5 days). There were no notable events in most of the procedures except in one procedure where the patient developed hypotension, her saturation started to drop, and the procedure had to be aborted.
CONCLUSION: Our study supports the effectiveness of timely initiation of plasma exchange to improve the overall mortality rate of the patients. |
