A 42-year-old man from New York City received a Lyme carditis diagnosis after quarantining in upstate New York during the COVID-19 pandemic. The case is discussed in the article “A curious case of Lyme carditis in an urban hospital,” by Brissett et al. 1 “Lyme carditis was a surprise diagnosis in our hospital due to the […]

In their article “Underrecognized Tickborne Illnesses: Borrelia Miyamotoi and Powassan Virus,” Della-Giustina et al. explain what is the Powassan virus and why it’s raising concerns. “We chose to review the Powassan virus because it only requires 15 min. of tick attachment for transmission, and the sequelae of the neurologic disease are devastating, in addition to

Adult-onset Still’s disease (AOSD) is often thought to be an autoimmune disease, but is, in fact, a systemic auto-inflammatory condition, believed to be caused by an over-reactive immune response to an infection, such as Lyme disease. As Cimmino points out, both diseases share several clinical characteristics.¹ Still’s disease can cause “a triad of high fever,

According to the American Lung Association, an “infection or exposure to something in the environment can trigger the immune system to overreact,” resulting in sarcoidosis.¹ In a 2018 study, van Dee and colleagues suggest that Borrelia burgdorferi, the Lyme disease bacterium, may be one of those infectious pathogens capable of triggering sarcoidosis. ² Their study

A study by Eisen and colleagues addressed a frequently asked question: “How long does it take to get Lyme disease?” According to their findings,  the probability of an individual becoming infected with Borrelia burgdorferi (Bb), the pathogen which causes Lyme disease, increases the longer the tick is attached. [1] Researchers found the risk increases: Approximately

This case report describes an elderly woman from Maine, who was diagnosed post-mortem with a rare deer tick virus, known as the Powassan virus. The 72-year-old woman was admitted to the hospital with myalgias, chills, and an erythema migrans rash on her left scapula. She reportedly had 2 tick bites over the course of one

Can Ticks Be Tested for Lyme Disease? Ticks can be tested for the Lyme disease bacteria and other tick-borne pathogens. But the accuracy of test results may depend on whether the tick is engorged. A study by Gasmi et al. found that results may not be accurate when testing ticks which are engorged. The authors

Stomach pain from Lyme disease sent a 71-year-old woman through extensive gastrointestinal workup—CT scans, PET scan, colonoscopy, gastroscopy, MRI of small intestines—all normal. Her severe abdominal pain wasn’t from her digestive system at all. It was neurologic Lyme disease causing radiculitis (nerve root inflammation) that mimicked a gastrointestinal disorder. After two weeks of IV ceftriaxone
