Trench fever in urban people who are homeless

A disease common during the First World War, trench fever, has been found in some urban populations experiencing homelessness in Canada, and physicians should be aware of this potentially fatal disease, highlights a practice article in CMAJ (Canadian Medical Association Journal).

The article describes a 48-year-old man who visited an in Manitoba with chest pain and shortness of breath. In the previous 18 months, the patient had sought care for episodes of and body lice infestation.

Bartonella quintana is a bacterium that is transmitted by body lice and causes a disease called , which killed millions of people during the First World War. It can lead to an infection of the heart, known as endocarditis, that can be fatal if untreated.

"Our public health message is that this disease is present in Canada and that people and physicians aren't always aware," says Dr. Carl Boodman, an infectious disease physician at the University of Manitoba, Winnipeg, Manitoba. "It's associated with homelessness and , and physicians should consider B. quintana infection in people who are unwell and have a history of body lice infestation."

The authors are aware of only 4 other cases in Canada over the last 20 years.

Symptoms of trench fever include fever, headache and malaise. It can be difficult to detect, requiring molecular testing and consultation with infectious disease experts.

"Clinicians should consider Bartonella serology, echocardiography and infectious disease consultation when caring for individuals who present unwell with a history of body lice infestation. B. quintana infection likely remains underdiagnosed," the authors conclude.
