Pseudohyperchloremia in a patient taking bromine-containing drug: a clinical case

The development of pseudohyperchloremia in bromine poisoning has been described in several clinical cases, as well as in the veterinary literature. Among the side effects of bromides, the likelihood of developing such condition has not been described. We report a case of pseudohyperchloremia in patients taking a bromine-containing multicomponent drug. Severe hyperchloremia was detected – 209 mmol/l and 233 mmol/l – in the absence of metabolic acidosis and negative anion gap. This case is the first Russian-language description of the phenomenon.
