We read with interest the article "Dengue infection presenting as acute hypokalemic quadriparesis" by Gupta et al.[1] and would like to make the following observations. As mentioned by the authors quadriparesis can occur rarely in dengue patients and the reported causes include acute disseminated encephalomyelitis, [2] acute transverse myelitis [3] and compressive myelopathy, [4] acute inflammatory demyelinating polyneuropathy, [5] acute motor sensory axonal neuropathy, [6] acute motor axonal neuropathy, [7] hypokalemic paralysis, [8],[9] neuralgic amyotrophy [10] and myostis. [11] The genesis of hypokalemia could also result from a host of causes that include redistribution of potassium into cells either due to increased catecholamine release and/or due to secondary insulin resistance, transient renal tubular abnormalities leading to increased urinary potassium wasting, increased potassium consumption due to rapid cell growth, potassium loss due to vomiting and diarrhea [11] and hyperreninemia due to hypovolemia.
