Acute Flaccid paralysis in adults: Our experience

Acute flaccid paralysis (AFP) is a complex clinical syndrome with a broad array of potential etiologies that vary with age. We present our experience of acute onset lower motor neuron paralysis. Materials and Methods: One hundred and thirty-three consecutive adult patients presenting with weakness of duration less than four weeks over 12 months period were enrolled. Detailed history, clinical examination, and relevant investigations according to a pre-defined diagnostic algorithm were carried out. The patients were followed through their hospital stay till discharge or death. Results: The mean age was 33.27 (range 13-89) years with male preponderance (67.7%). The most common etiology was neuroparalytic snake envenomation (51.9%), followed by Guillain Barre syndrome (33.1%), constituting 85% of all patients. Hypokalemic paralysis (7.5%) and acute intermittent porphyria (4.5%) were the other important conditions. We did not encounter any case of acute polio mylitis in adults. In-hospital mortality due to respiratory paralysis was 9%. Conclusion: Neuroparalytic snakebite and Guillain Barre syndrome were the most common causes of acute flaccid paralysis in adults in our study.
