Antibiotic-associated acute kidney injury (AA-AKI) is quite common, especially among hospitalized patients; however, little is known about risk factors or mechanisms of why AA-AKI occurs. In this review, the authors have reviewed all available literature prior to 1 June 2022, with a large number of AKI reports. Information regarding risk factors of AA-AKI, mechanisms behind AA-AKI, and treatment/management principles to decrease AA-AKI risk were collected and reviewed. Patients treated in the inpatient setting are at increased risk of AA-AKI due to common risk factors: hypovolemia, concomitant use of other nephrotoxic medications, and exacerbation of comorbid conditions. Clinicians should attempt to correct risk factors for AA-AKI, choose antibiotic therapies with decreased association of AA-AKI to protect their high-risk patients, and narrow, when clinically possible, the use of antibiotics which have decreased incidence of AKI. To treat AKI, it is still recommended to discontinue all offending nephrotoxic agents and to renally adjust all medications according to package insert recommendations to decrease patient harm.

Introduction: Neuropsychiatric disorders affect millions of older adults. Despite this, there are relatively few older adults included in clinical trials evaluating treatments for psychiatric disorders. Citalopram has been evaluated in older adults with neuropsychiatric disorders and has largely been found beneficial, making the 2011 US Food and Drug Administration (FDA) safety advisory on citalopram extremely impactful. Methods: A literature search was completed using the PubMed database. Results were limited to clinical trials conducted in older adults that were published in English. Results: Review of the literature confirms the efficacy of citalopram in depression, anxiety, depression associated with Parkinson disease, and behavioral and psychological symptoms of dementia. Additionally, no adverse cardiac outcomes have been described related to citalopram. Discussion: The FDA's evidence for applying this safety advisory to citalopram is minimal and largely based on surrogate markers, such as the QTc interval rather than clinical and safety outcomes. Citalopram is known to increase the QTc, but this increase has not been linked to adverse cardiac outcomes. The evidence for efficacy and against adverse outcomes suggests that a reevaluation of the dosing restrictions in older adults with neuropsychiatric disorders is needed.

The patient is a 75-year-old male who was admitted to the long-term care unit because of advancing dementia and was being treated with mirtazapine to improve his mood and stimulate his appetite. This case report outlines an interesting occurrence of hypertriglyceridemia followed by hyperglycemia, which resembled diabetes mellitus and required insulin therapy. The patient continued to have elevated triglyceride levels that persisted despite discontinuation of mirtazapine therapy.
