Delayed onset of Babesia highlights importance of follow-up visits

A recent case report published in the British Medical Journal demonstrates the importance of monitoring patients with Lyme disease even after initial treatment, as co-infections can surface at a later stage.

Don’t be misled: patients can have both mono and Lyme disease

Mononucleosis (EBV) and Lyme disease share similar characteristics, making an accurate diagnosis difficult. Each condition causes non-specific symptoms including fatigue, fever, myalgia, arthritis, headaches, neck soreness and swollen or enlarged lymph nodes. And each greatly impacts children. While mono is a common childhood illness,  25% of all Lyme disease cases in the US involve children. 

Infected ticks prevalent in urban areas in the United Kingdom (UK)

The prevalence of vector-borne diseases in Europe, including the UK, has changed dramatically over the past 15 years. Today, there are regular outbreaks of West Nile, chikungunya, and dengue viruses. Malaria has returned. The number of Lyme disease cases is rising and tick-borne encephalitis virus is expanding to the northern regions of Europe. Meanwhile, new pathogens continue to be discovered, such as Borrelia miyamotoi and various tick-borne rickettsiae.

First-line combination therapy for tick-borne illnesses

Black-legged ticks can carry and transmit multiple pathogens causing a range of different diseases including Lyme disease, Babesia, anaplasmosis, Borrelia miyamotoi, ehrlichiosis and the Powassan virus. In fact, an individual can develop several diseases from just a single tick bite.

Neurologic Lyme disease presenting as abdominal pain in 71-year-old patient

“Although abdominal pain is generally not considered a sign of LD [Lyme disease], in this case report we describe a patient with unexplained severe abdominal pain that eventually turned out to be LD due to radiculopathy,” explains Stolk from the Haga Teaching Hospital in the Netherlands. [1]

Can we avoid using a pacemaker for Lyme carditis with high-degree AV block?

A pacemaker implantation is typically an effective treatment for patients with high-degree atrioventricular (AV) block due to Lyme carditis (LC). “However, the AV block in LC may revert back to normal conduction and usually resolves within the first 10 days of antibiotic administration,” says Yeung from Queen’s University in Kingston, Ontario. [1] “If the AV block in LC is indeed transient, then a permanent pacemaker is not indicated.”

Can Lyme disease trigger an autoimmune disease?

Adult-onset Still’s disease (AOSD) is an autoimmune condition which can cause symptoms similar to those seen with Lyme disease. In fact, several case reports have shown that Lyme disease can mimic AOSD. But now researchers describe the first known case of Lyme disease triggering AOSD.

10 cases of Heartland virus reviewed

This past week, Illinois health officials reported the first case of Heartland virus in their state. The disease, believed to be spread by the lone star tick, is relatively new. Although it was first identified in 2009 in Missouri, it wasn’t described in the medical literature until 2012, when researchers from the Centers for Disease Control and Prevention (CDC) announced that the virus could be “a more common cause of human illness than is currently recognized.” [1]

Lyme disease remains a threat to international travelers to the US

Researchers have primarily studied travel-related illnesses in individuals travelling from high-income countries (such as the United States) to low- and middle-income countries. But now as vector-borne diseases, including Lyme disease, become a growing threat in the USA, researchers are switching their attention to the dangers now faced by travelers visiting the States.

Citizen scientists help uncover growing risk of Babesia

Tick-borne pathogens have expanded into new geographical territories across the United States resulting in a greater incidence of tick-related diseases. Gathering data to understand patterns of exposure to tick bites and the risk of disease on a national level is becoming increasingly important. As a result, researchers have teamed up with citizen scientists (members of the public) to help collect samples and data.
