A dog can be man’s best friend, particularly when it comes to helping identify the risk of tick-borne diseases for humans. The true spread of Babesia may currently be underestimated, under-reported, and untreated, writes Mahachi and colleagues in the journal Parasites Vectors.¹ But new research indicates that hunting dogs can offer insight into the distribution of Babesia in the Southern and Western USA.
Some medical professionals and their patients have dismissed Lyme disease, believing the prevalence and potential damage a Lyme infection can cause is over-exaggerated. But what happens if your family is directly affected? A researcher from the University of Pennsylvania shares his story “Lemons and Lyme” in the Journal of the Pediatric Infectious Diseases Society.
Postural tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance which affects circulation or blood flow. It’s typically triggered when a person suddenly stands up after lying down. The primary symptoms include lightheadedness, fainting and an uncomfortable, rapid increase in heartbeat.
A recent article by Carriveau and colleagues recommends that a single dose of doxycycline should be prescribed to children following a tick bite to prevent Lyme disease.¹ Unfortunately, there is no evidence to support this recommendation.
Individuals with a weakened immune system are more susceptible to developing infections, such as COVID-19. A review study has also found that people with compromised immune systems are at a greater risk of developing disseminated Lyme disease. The authors of “Erythema Migrans: Course and Outcome in Patients Treated With Rituximab” investigated patients diagnosed with Lyme disease, who were also taking Rituximab, a medication known to impair immunity. 
In a recent editorial, Dr. Allen Steere describes the clinical features and proposed mechanisms triggering what he believes are 4 distinct post-treatment Lyme disease syndromes (PTLDS) in patients who fail antibiotic treatment for Lyme disease. 
Patients with Lyme disease are typically treated with a standard antibiotic, which may include doxycycline, amoxicillin, or cefuroxime, for a 2 to 4 week period. However, studies have shown that between 36-63% of treated patients continue to suffer with persistent symptoms. 
Chronic pain, debilitating fatigue, and heightened sensory disturbances are common in Lyme disease patients. In their article, “Post-Treatment Lyme Syndrome and Central Sensitization,” Batheja and colleagues suggest that, in some cases, such symptoms may be due to central sensitization syndrome (CSS). 
Atrial fibrillation, the most common type of arrhythmia (irregular heartbeat), can increase your risk of strokes, heart disease or other heart-related complications. In many cases, atrial fibrillation is associated with a history of cardiac inflammation, writes Szymanska et al. in their article “History of Lyme Disease as a Predictor of Atrial Fibrillation.”
A study by Stanford Medicine indicates that a drug called azlocillin “completely kills off the disease-causing bacteria Borrelia burgdorferi at the onset of the illness.”  In addition, the authors say, azlocillin “could be effective for treating [Lyme disease] patients infected with drug-tolerant bacteria that may cause lingering symptoms.”
Dr. Daniel Cameron, MD, MPH, is a nationally recognized leader for his expertise in the diagnosis and treatment of Lyme disease and other tick-borne illnesses. For more than 30 years, he has been treating adolescents and adults suffering from Lyme disease.
