Objectives:
We have preciously documented that many individuals with acute mania have immune activation. However, the sources of immune activation have not been identified. We investigated whether individuals hospitalized with acute mania have evidence of bacterial infections as determined by the prescription of systemic antimicrobial agents.
Methods:
We assessed the recent prescription of systemic antimicrobial medications and the site of presumed bacterial infection in 234 individuals hospitalized for acute mania in either an inpatient unit or a day hospital. We also assessed individuals hospitalized for other psychiatric disorders (n=368) and controls (n=555). We employed logistic regression models to compare the rates of antibiotic prescription in individuals with the different diagnoses, employing demographic variables as covariates.
Results:
We found that individuals hospitalized with acute mania had a substantially increased rate of recent antimicrobial prescription, defined as exposure within three days of ascertainment (adjusted odds ratio=5.5, 95% confidence interval: 2.2-14.1, P<.0002). Overall, a total of 18 of the 234 (7.7%) individuals hospitalized for acute mania were prescribed antibiotics as opposed to seven of 555 (1.3%) controls. The prescription of antibiotics was associated with being on an inpatient unit as opposed to being in the day hospital, and having increased mania symptom severity but not with other clinical ratings, demographic variables, or psychiatric medications. Hospitalization for other psychiatric disorders was not associated with the recent prescription of antimicrobial medications. The urinary tract was the most common site of infection in women, while the respiratory tract and mucosal surfaces were the most common sites in men.
Conclusions:
Individuals hospitalized with acute mania have a markedly increased rate of bacterial infections, as evidenced by the recent prescription of antimicrobial agents. The prevention and effective treatment of bacterial infections may be important interventions for the management of individuals with mania.
Insights
Individuals with acute mania show significantly higher rates of bacterial infections, indicated by antibiotic prescriptions. Addressing these infections could be key in managing mania symptoms and improving patient outcomes.
Area of Science:
- Psychiatry
- Infectious Diseases
- Immunology
Background:
- Acute mania is associated with immune activation, but the source remains unclear.
- Bacterial infections are a potential, yet under-investigated, contributor to immune activation in acute mania.
Purpose of the Study:
- To investigate the prevalence of bacterial infections in individuals hospitalized with acute mania.
- To determine if bacterial infections, evidenced by antimicrobial prescriptions, are a source of immune activation in acute mania.
Main Methods:
- Retrospective assessment of systemic antimicrobial prescriptions in 234 individuals hospitalized for acute mania.
- Comparison of antibiotic prescription rates between acute mania patients, other psychiatric disorder patients (n=368), and controls (n=555).
- Logistic regression analysis was used to compare antibiotic prescription rates, controlling for demographic variables.
Main Results:
- Individuals with acute mania had a significantly higher rate of recent antibiotic prescription (7.7%) compared to controls (1.3%).
- Antibiotic prescription was linked to inpatient status and mania symptom severity, not other clinical or demographic factors.
- Common infection sites included the urinary tract in women and respiratory/mucosal sites in men.
Conclusions:
- Hospitalized individuals with acute mania exhibit a substantially elevated incidence of bacterial infections.
- Effective prevention and treatment of bacterial infections may represent crucial therapeutic strategies for managing acute mania.
