Depression common in Lyme disease patients

There is still reservation among some in the medical community as to whether mood disorders, such as depression, are, in fact, associated with Lyme disease. The authors of a study published in Clinical Infectious Diseases explore the possible connection.

Child with Lyme disease presenting as pseudotumor cerebri

In a letter to the editor of the Journal of Pediatrics and Child Health, doctors describe the case of a 6-year-old girl with pseudotumor cerebri who was diagnosed with Lyme disease. [1] Pseudotumor cerebri is a neurologic condition that has also been called idiopathic intracranial hypertension or benign intracranial hypertension.

Case series shows wide range of Babesia symptoms and presentations

Babesia can be a serious tick-borne illness in some patients. A case series published in the Nurse Practitioner Journal demonstrates the difficulty in diagnosing the disease, as it can cause a wide range of clinical presentations. The authors focus on five cases which occurred in southeastern New Jersey, an area endemic for Babesia. All of the patients were hospitalized.

Case report: Lyme neuroborreliosis more common in children

In Europe, neurologic manifestations of Lyme disease are more likely to occur in children than adults. The authors of an article published in the Journal of Medical Microbiology Reports describe the case of a young boy who suffered a series of neurologic complications over several years due to Lyme disease. [1] A review of the case demonstrates the difficulties in unraveling the cause of neurologic events in patients with a history of Lyme disease.

Persister cells still a problem for Lyme disease patients

Bacterial persistence is not a new concept. “The term “bacterial persistence” is used to describe the ability of pathogenic bacteria (“persisters”) to survive in infected host tissues despite the presence of effective levels of antimicrobials and antibacterial cellular and humoral immunity,” writes Cabello from New York Medical College in the journal Environmental Microbiology.

Blood donor infects premature infants with Babesia

Babesia is a parasite which infects red blood cells, causing symptoms similar to those seen with malaria. It’s typically transmitted by a tick bite but can be acquired through contaminated blood transfusions. The disease can be extremely difficult to recognize in adults. Imagine the challenge of diagnosing it in premature infants.

European Ixodes tick found to carry Alpha Gal protein associated with red meat allergy

Studies have found an association between tick bites, specifically from the species Amblyomma americanum, also known as the Lone Star tick, and red meat allergies. “An association between tick bites, the development of immunoglobulin E (IgE) antibodies to galactose-α-1, 3-galactose (α-Gal or Alpha Gal) and red meat allergy has recently been reported,” explains the authors of an article published in PLoS One journal. [1]

Congenital transmission of babesiosis: two case reports

Congenital babesiosis is considered a rare disease with only nine cases reported in the U.S. - all in the northeastern region where babesiosis is endemic. Now, the authors of an article published in the Journal of the Pediatric Infectious Diseases Society [1] discuss two new cases of congenital babesiosis.

Case Report: Fatal Powassan virus infection: a.k.a. Deer tick virus

It is estimated that 1% - 3% of blacklegged ticks (I. scapularis) in the northeastern United States may be infected with Powassan virus (POWV), lineage II, otherwise known as the deer tick virus (DTV).

Borrelia miyamotoi detected in Canada

In 2013, the first cases of Borrelia miyamotoi in North America were reported in the northeastern United States. Cases have also been described in Russia, the Netherlands, Germany, Japan and the upper Midwestern United States. Ixodes ticks infected with B. miyamotoi have been found in other regions including several Canadian provinces, according to a study published in the Canadian Medical Association Journal by Kadkhoda and colleagues. [1] But human cases of the disease have yet to be identified in this region.
