Trends in Characteristics of Prescription Opioid-related Poisonings among Older Adults in the United States, 2015-2021.

OBJECTIVES: Few studies have considered how trends in opioid poisonings have changed among older adults. The objective of this study was to examine trends in fatal and nonfatal opioid-related poisonings ("exposures") among older adults. METHODS: National poison center data were used to examine trends in characteristics of reported exposures to commonly prescribed opioids between 2015 and 2021 among adults 60 years or older. We estimated the proportion of opioid exposures by demographic characteristics, the specific opioid(s) involved, exposure type, route of administration, other substances co-used, and medical outcomes for each calendar year. We estimated whether there were linear changes in prevalence by year using logistic regression. RESULTS: Although there was a decrease in the number of opioid exposures within the study population from 7706 in 2015 to 7337 in 2021 (a 4.8% decrease, P = 0.04), exposures increased for adults aged 70 to 79 years (a 14.0% increase, P < 0.001). The proportion classified as "abuse" increased by 63.3% ( P < 0.001). There were significant decreases in the proportion involving hydromorphone (a 23.3% decrease, P < 0.001) and morphine (a 22.0% decrease, P < 0.001), with an increase involving buprenorphine (a 216.0% increase, P < 0.001). The proportion increased for co-use of cocaine (a 488.9% increase, P < 0.001) and methamphetamine (a 220.0% increase, P = 0.02), with a decrease in co-use of benzodiazepines (a 25.5% decrease, P < 0.001). The proportion of major medical outcomes increased by 93.9% ( P < 0.001). CONCLUSIONS: National patterns of opioid-related poisonings are shifting among older adults, including the types of opioids involved and co-use of other drugs. These results can inform prevention and harm reduction efforts aimed at older adults.

A simultaneous presentation of drug-induced lupus with drug-induced ANCA vasculitis secondary to hydralazine use in a patient with sarcoidosis.

Frequently used in the management of hypertension and heart failure, hydralazine is associated with the development of adverse rheumatologic side effects. The authors highlight a unique case of drug-induced lupus and drug-induced anti-neutrophil cytoplasmic antibody (ANCA) vasculitis from hydralazine use in a 50-year-old man with sarcoidosis and hypertension.

Conservative management of severe serotonin syndrome with coma, myoclonus, and crossed-extensor reflex complicated by hepatic encephalopathy.

Serotonin syndrome (SS) is an underrecognized and potentially fatal disorder that occurs secondary to combinational use or overdose of a single serotonergic medication. The presentation may be complicated by hepatic encephalopathy in cirrhotic patients, which may also affect metabolism of these serotonergic agents. The authors report a rare case of severe SS complicated by hepatic encephalopathy secondary to cirrhosis in a 52-year-old woman after an increase in her home dosage of fluoxetine and addition of other psychiatric medications.
