Decreased susceptibility to azithromycin in clinical Shigella isolates associated with HIV and sexually transmitted bacterial diseases, Minnesota, USA, 2012–2015
Emerging Infectious Diseases Mar 13, 2020
Eikmeier D, Talley P, Bowen A, et al. - Given the worldwide reporting of Shigellosis outbreaks caused by Shigella with decreased susceptibility to azithromycin (DSA-Shigella) among men who have sex with men (MSM), researchers sought to report sexual health indicators and antimicrobial drug resistance for shigellosis cases in Minnesota, USA. They performed analysis of a sample of isolates received during 2012–2015 as well as cross-referenced cases with the Minnesota Department of Health Sexually Transmitted Disease Database to determine patients’ HIV status and recent chlamydia, gonorrhea, and syphilis infections. Amongst 691 Shigella isolates, 46 (7%) were identified as DSA-Shigella. Among DSA-Shigella patients, 91% were men, of whom 60% were living with HIV. Greater odds of living with HIV, identifying as MSM, or having a recent diagnosis of a sexually transmitted disease were observed among men with DSA-Shigella infection. They observed an association of DSA-Shigella with MSM, HIV infection, and recent sexually transmitted disease. Findings suggest the necessity for interventions targeting communities at high risk in order to reduce the spread of DSA-Shigella.
