Colistin-induced myasthenic syndrome in a patient with end-stage renal disease

With resurgence of multidrug resistance (MDR) bacteria and no new novel broad-spectrum antibiotic in research pipeline, usage of older generation antibiotics, once discarded due to their toxicity profile are becoming popular again. Often these drugs are the only option left in managing MDR bacteria-related sepsis. Colistin is one of such antibiotic which is often used in recent times after decades of its avoidance due to its diverse toxicity profile. In this case report, we present a rare myasthenic syndrome like neuromuscular complication developed in a patient after receiving colistin for treatment of MDR Klebsiella-related urosepsis.
