Abstract

Nonacetylated salicylates are frequently used in the treatment of musculoskeletal complaints and pain management in older patients because of their possible lower gastrointestinal and renal toxicity as compared with other nonsteroidal anti-inflammatory agents. We report five patients with chronic salicylate intoxication seen at the Atlanta VA Medical Center. All charts of patients diagnosed with salicylate toxicity were reviewed, and cases with acute, intentional intoxication were excluded. In the study group, three patients took a nonacetylated salicylate, the other two took an acetylated salicylate. Our patients ranged in age from 51 to 78 years old. One patient died of respiratory failure and "sepsis-like syndrome," a potentially lethal complication of salicylate toxicity. Four of the patients had altered mental status as a presenting complaint. The presence of a combined respiratory alkalosis and metabolic acidosis, present in all five patients, was the clue for diagnosis in three of the cases. Tinnitus was reported in only one patient. A significantly decreased urate level and a wide anion gap were consistent findings as well. Two of the patients improved after hydration and discontinuation of use of the drug, two required alkalinization of the urine, and one required dialysis. Clinicians need to be more aware of the potential toxicity, including life-threatening complications, with the use of salicylates, particularly in high risk populations such as elderly patients and patients with multiple medical problems.
