Immunoblot reactivity at follow-up in treated patients with Lyme neuroborreliosis and healthy controls

Publication date: Available online 26 September 2018Source: Ticks and Tick-borne DiseasesAuthor(s): R. Dersch, A. Sarnes, M. Maul, O. Minakowski, T. Hottenrott, O. Stich, S. RauerAbstractAbout 5–20% of the general population in endemic areas have seroprevalence for anti-borrelial antibodies. Previous studies have shown a high rate of 25–97% of persisting anti-borrelial antibodies in patients with treated Lyme neuroborreliosis (LNB) at follow-up. These studies used immunoblots with antigens from whole-cell sonicates, which could be less specific than modern recombinant antigens. We assessed the seroprevalence of anti-borrelial antibodies in serum from patients with definite LNB and healthy controls with a line immunoblot using highly specific recombinant antigens.We retrospectively identified patients with treated definite LNB who were treated at the Medical Center–University of Freiburg. Serum from LNB patients at a mean follow-up period of 4.9 years (SD: 3.3) and serum from healthy controls were assessed for anti-borrelial antibodies with a line immunoblot with recombinant antigens.A total of 45 patients with definite LNB and 40 healthy controls were included. Ten LNB patients (22.7%) had persisting antibodies (IgG and/or IgM) in serum at follow-up. Serum samples from six healthy controls (15%) were positive for anti-borrelial antibodies (IgG and or IgM). Prevalence of positive IgM or IgG antibodies showed no statistically significant difference between LNB...

Lyme disease (LD) is an increasing public health problem. Current laboratory testing is insensitive in early infection, the stage at which appropriate treatment is most effective in preventing disease sequelae. The Lyme Disease Biobank (LDB) collects samples from individuals with symptoms consistent with early LD presenting with or without erythema migrans (EM) or an annular, expanding skin lesion and uninfected individuals from areas of endemicity. Samples were collected from 550 participants (298 cases and 252 controls) according to institutional review board-approved protocols and shipped to a centralized biorepository....

The laboratory diagnosis of Lyme disease relies upon serologic testing. A standard or modified two-tiered testing algorithm is used to enhance the accuracy of antibody detection. However, this approach suffers from a lack of sensitivity in early Lyme disease. Ongoing efforts to develop more sensitive antibody detection technologies and other diagnostic approaches are dependent upon the availability of quality-assured biospecimens linked to reliable clinical data.

Lyme borreliosis is a tick-borne disease caused by the Borrelia burgdorferi sensu lato complex. Bio-Rad Laboratories has developed a fully automated multiplex bead-based assay for the detection of IgM and IgG antibodies to B. burgdorferi. The BioPlex 2200 Lyme Total assay exhibits an improved rate of seropositivity in patients with early Lyme infection. Asymptomatic subjects from endemic and nonendemic origins demonstrated a seroreactivity rate of approximately 4% that was similar to other commercial assays evaluated in this study. Coupled to this result was the observation that the Lyme Total assay retained a high first-t...

Lyme disease is a tick-borne spirochete illness with multi-system involvement. Although neurological manifestations of Lyme disease are becoming increasingly well recognized, its psychiatric presentations are not well known. Physicians need to be aware of its neuropsychiatric symptoms that may present months to years later. Endemic areas to Borellia Burgdorferi also have higher rates of schizophrenia. Prompt diagnosis and effective treatment is need to to avoid irreversible neuropsychiatric complications.

Conclusions: This study found a high incidence of Lyme disease in Lithuania. We elucidated the baseline characteristics regarding the infected Lithuanian population which may ease medical clinicians' work on new Lyme diagnoses. PMID: 32151097 [PubMed - in process]

Abstract Ixodes scapularis is currently known to transmit 7 pathogens responsible for Lyme disease, anaplasmosis, babesiosis, tick-borne relapsing fever, ehrlichiosis, and Powassan encephalitis. Ixodes scapularis can also be colonized by endosymbiotic bacteria including those in the genus of Rickettsia. We screened 459 I. scapularis ticks submitted to the Connecticut Agricultural Experiment Station Tick Testing Laboratory with the objectives to (1) examine differences in infection prevalence of Borrelia burgdorferi, Anaplasma phagocytophilum, Babesia microti, and Borrelia miyamotoi, (2) evaluate whether prevalence...

AbstractPurpose of reviewThis review describes mosquito- and tick-borne diseases found in the Western Hemisphere. It focuses on emerging diseases and recent geographic shifts in the presence of disease vectors.Recent FindingsMosquito and tick vectors have become more widespread as environmental conditions have become more favorable. Zika recently has emerged as a concern for fetal anomalies. West Nile Virus has become widespread. Lyme disease and other tick-borne diseases are more prevalent in areas previously inhospitable to these ticks.SummaryHealthcare providers must consider the possibility of mosquito- and tick-borne ...
