ABSTRACT

A significant segment of the United States adult population is obese. Bariatric surgery is one approach to weight loss when nonsurgical efforts have failed. In individuals with a body mass index ≥50, gastric reduction with duodenal switch is more effective than gastric bypass. More than half of bariatric surgery candidates report a history of mental illness and more than one third were taking at least one psychotropic medication at the time of surgery. Thus, the impact of surgery on absorption of psychiatric medications should be considered. Lurasidone, a second-generation antipsychotic used to treat schizophrenia and bipolar disorder, is recommended to be taken with food of at least 350 calories. We describe the case of a patient with incomplete response to lurasidone therapy in the year following a duodenal switch procedure. This case raises concern about the effect that the duodenal switch procedure may have on lurasidone absorption.

ABSTRACT

OBJECTIVE: To report a case of indinavir-induced urolithiasis, and the greater risk of this occurrence in individuals with spinal cord injury (SCI) who require fluid restriction for an intermittent catheterization program (ICP). METHODS: Case report. RESULTS: A 38-year-old man with a T4 ASIA A SCI (according to the American Spinal Injury Association classification scale) and human immunodeficiency virus (HIV) infection was using an ICP and taking indinavir (a protease inhibitor) as part of his antiviral regimen. Cystoscopy was performed to rule out recurrent urethral condylomata. He was found to have a bladder stone measuring 0.5 cm x 0.5 cm x 0.3 cm, which, on analysis, was composed of indinavir (100% exterior, 90% interior). The bladder stone was removed under direct visualization. The plain abdominal radiograph did not reveal any stones. CONCLUSION: Indinavir is a frequently used drug for the treatment of HIV that has the potential to induce urinary lithiasis. This is particularly problematic for individuals with SCI who are on fluid restriction and an ICP. Therefore, cystoscopy and monitoring for indinavir-induced urolithiasis should be undertaken in individuals with SCI who are taking indinavir. Considerations include switching to a different protease inhibitor or choosing an entirely new HIV drug cocktail with less potential for urolithiasis.
