Lot number and expiry information are not available at this time. Investigation: patient had no past medical history. Patient was hospitalized for 3 months following myasthenia crisis, with chronic respiratory failure requiring tracheotomy and mechanical ventilatory support. The management of this refractory myasthenia was based on acetylcholinesterase inhibitors, corticosteroids, rituximab, and thymectomy. After a new relapse, daily tpes were started, with 4% albumin as the replacement fluid, which had a sodium concentration of 148 mmol/l and chloride concentration of 145 mmol/l. After the second saily tpe, the patient had a hyperchloremic metabolic acidosis reaction, so every other day tpes were started. Subsequent exchanges were spaced (every other day) and performed with less volume (1. 2 plasma volume). Laboratory tests performed after the next exchange showed an elevation of chloride at 110 mmol/l, but without significant acidosis. The analysis of substitution 4% albumin solution revealed a sodium concentration of 148 mmol/l and chloride concentration of 145 mmol/l. This acidosis is due to a reduction of the strong anion gap by an excessive rise of plasma chloride as well as a disproportionate renal bicarbonate elimination.

Per an article in journal of clinical apheresis, a myasthenia gravis patient was started on every-other-day therapeutic exchange procedures (tpe) following a hyperchloremic metabolic acidosis reaction on daily tpes. Laboratory tests performed after the next exchange showed an elevation of chloride at 110 mmol/l, but without significant acidosis. Is unknown at this time if medical intervention was required for the elevated chloride level. The disposable set is not available for return because it was discarded by the customer. This product is not available within the us, but this report is being filed due to an alleged failure that could occur on a similarly marketed device platform cleared for use by the fda.
