Abstract

Background: Borreliosis infection and post-treatment Lyme disease syndrome are associated with nonspecific, multisystem symptoms, and there is currently no effective direct test for Lyme disease. The seroprevalence of Borrelia miyamotoi among individuals with suspected tick-borne illnesses and persistent symptoms is not well documented. Although bacterial extracellular vesicles (BEVs) have been suggested as potential sources of disease biomarkers, evidence supporting their role in Borrelia infection is lacking.

Methods: Patients (N=66) with symptoms and with clinical suspicion of a tick-borne illness were enrolled in the study and followed longitudinally over the course of 1 year (min 1 visit, max 4 visits). The General Symptom Questionnaire (GSQ-30) was administered to the patients at each visit to measure symptom burden. Lyme and Borrelia miyamotoi serologies were conducted at LabCorp or Quest, under the standard of care. A mass spectrometry proteomic assay measuring Borrelia-specific peptides was conducted in the urine of the patients.

Results: Among the analyzed patients, 65% had positive Lyme serology and 33% had positive B. miyamotoi serology with partial overlap (20%). Urinary Borrelia-specific peptides correlated with the GSQ-30 score after correcting for age, Lyme serology, and B. miyamotoi serology (coefficient = 0.57, t-test p-value < 0.00001). Urinary extracellular vesicles had positive reactivity in a p66 immunoassay, a known marker of Borrelia BEVs. Urinary peptides included glycerophosphodiester phosphodiesterase, variable small and large outer membrane proteins, the multicopy lipoprotein family, and Borrelia direct repeat proteins, which are also known markers of Borrelia BEVs.

Conclusions: The B. miyamotoi seroprevalence (33%) in a symptomatic population with clinical suspicion of a tick-borne illness was higher than the seroprevalence estimated from previous studies. As it provides an objective measurement correlated with a standardized symptom burden score, urinary Borrelia peptide detection offers a promising avenue for future assay development. This proteomic analysis supported the presence of Borrelia BEVs in the urine of symptomatic patients with suspected tick-borne illnesses.

Healthy Fetal Outcomes Using a Novel Treatment for Maternal Lyme Disease and Babesiosis During Consecutive Pregnancies: A Case Study and Literature Review

Babesia is a single celled protozoan parasite which may be transmitted through the bite of an infected tick, blood transfusion and/ or maternal-fetal transmission. We describe the case of a woman previously treated for Lyme disease and babesiosis who relapsed with severe malaria-like symptoms during the 3rd trimester of two consecutive pregnancies.

The Dual Role of Macrophages during Hepatitis B Infection

Hepatitis B virus (HBV) chronically infects more than 250 million individuals worldwide and is responsible for more than 800,000 deaths per year by promoting end-stage liver diseases, among which decompensated cirrhosis and hepatocellular carcinoma (HCC) (WHO, July 2020) are prominent. Studies performed in chimpanzees or in animalversion of HBV (woodchuck HBV: WHBV) highlighted the lack of immune responses against the virus upon primary infection.

What Can Go Wrong When Applying Immune Modulation Therapies to Target Persistent Bacterial Infections

Antibiotics can treat the acute phase of a disease, but often do not completely clear the etiologic agent, allowing the pathogen to establish persistent infection that can revive the disease in a frustrating recurrence of infection. The mechanisms that control chronic bacterial infections are complex and involve pathogen adaptations that favor survival from both host immune responses and antibiotic bactericidal activity.

Tenofovir at the Crossroad of the Therapy and Prophylaxis of HIV and HBV Infections

Tenofovir, alias (R)-PMPA, was first divulged as an anti- HIV agent in 1993 [1]. That it would in 2012, become the first antiretroviral agent, approved by the US FDA (Food and Drug Administration) to prevent HIV infection, could have been predicted from the findings of Tsai et al.

Extragastric Manifestations of Helicobacter pylori Infection: A Commentary

Helicobacter pylori (Hp) is characterized as a gram-negative bacterium with microaerophilic metabolism, flagellated and helix-shaped that affects approximately 50% of the world population and, in some regions, this rate can exceed 80%. Hp infection is well known to infect the epithelial tissue of the stomach, being involved with development of many stomach diseases, including gastric carcinoma.
