To determine the frequency of confirmed Lyme neuroborreliosis (LNB) cases in adult patients with three different clinical presentations consistent with early LNB. Data were obtained through routine health care at the UMC Ljubljana, Slovenia from 2005-2022, using clinical pathways. The patients were classified into three groups: i) radicular pain of new onset (N = 332); or ii) involvement of cranial nerve(s) but without radicular pain (N = 997); or iii) erythema migrans (EM) skin lesion(s) in conjunction with symptoms suggestive of nervous system involvement but without either cranial nerve palsy or radicular pain (N = 240).

Methods: Data were obtained through routine health care at the UMC Ljubljana, Slovenia from 2005 to 2022, using clinical pathways. The patients were classified into three groups: (i) radicular pain of new onset (N = 332); or (ii) involvement of cranial nerve(s) but without radicular pain (N = 997); or (iii) erythema migrans (EM) skin lesion(s) in conjunction with symptoms suggestive of nervous system involvement but without either cranial nerve palsy or radicular pain (N = 240).
Purpose: Diagnosis of (European) Lyme neuroborreliosis has been based on clinical presentation, cerebrospinal fluid (CSF) pleocytosis and demonstration of intrathecal borrelial antibody synthesis (ITBAS) to document Borrelia burgdorferi s. l.
Infection: It is not known if other criteria to document Borrelia infection may contribute to the diagnosis.
Purpose: Since some patients with tick-borne encephalitis (TBE) have pronounced myalgias, and since myositis is reported in diseases such as dengue, we performed systematic search for abnormalities of muscle enzymes in a group of patients in whom the presence of tick-borne encephalitis virus (TBEV) RNA in the first phase of the disease was demonstrated and who developed second phase of TBE.
Methods: Total leukocyte and platelet blood counts were determined routinely at the initial examination during the first and the second phase of TBE. Activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK), myoglobin and troponin was determined from the available stored serum specimens; the first and second phase disease specimens were tested simultaneously.
In prior studies, the skin lesion erythema migrans (EM) was present for a longer time period before diagnosis of concomitant borrelial meningoradiculoneuritis (Bannwarth's syndrome) compared to EM patients without neurologic symptoms. To determine if this observation pertains to other manifestations of Lyme neuroborreliosis (LNB), we compared EM characteristics in patients with borrelial meningoradiculoneuritis (n = 122) to those with aseptic meningitis without radicular pain (n = 72 patients), and to patients with EM but without neurologic involvement (n = 12,384). We also assessed factors that might impact duration.

Sensation seeking (SS) is a psychobiological personality trait characterized by an individual's propensity to engage in various forms of risk-taking behavior. The Brief Sensation Seeking Scale (BSSS-8) is a widely used instrument for assessing SS that has been translated into several languages. However, only outdated and non-validated questionnaires have been used to measure SS in the Slovenian population.

We tested whether those symptoms are caused by maladaptive immune responses by measuring 20 immune mediators in serum and cerebrospinal fluid (CSF) in 79 LNB patients followed for 1 year. At study entry, most mediators were highly concentrated in CSF, the site of the infection.

Because TBE is not yet suspected during the initial phase, knowledge of early TBE pathogenesis is incomplete. Herein we evaluated laboratory and immune findings in the initial and second (meningoencephalitic) phase of TBE in 88 well-defined adult patients.

Methods: Extensive literature search has been done for available data on vaccine safety, efficacy and immunization recommendations in patients with neuromuscular disease in general and when receiving immune-modulating treatments.
Results: Vaccinations have been associated with some neuromuscular diseases, but these occurrences are very rare and should not influence the general vaccination recommendations for the pediatric population and for the especially vulnerable patient populations, such as neuromuscular disease patients.
Background: There is a general assumption that after deposition into skin, Lyme borreliae disseminate hematogenously to other organs, resulting in extracutaneous manifestations of Lyme borreliosis, including Lyme neuroborreliosis. However, our experience over the past 40 years, along with several published case reports that observed colocalization of radicular pain and erythema migrans (EM) in patients with borrelial meningoradiculoneuritis (Bannwarth syndrome), argues against hematogenous dissemination in Lyme neuroborreliosis.
Methods: We compared the location of EM in 112 patients with Bannwarth syndrome to 12315 EM patients without neurological involvement.
To assess whether differences in presentation between US and European patients with early Lyme borreliosis are due to the lower rate of spirochetemia in Europe, we compared multiple variables for patients with erythema migrans (EM), restricting the analysis to subjects with a positive blood culture at the time of presentation: 93 US patients infected with versus 183 European patients infected with (No = 144) or (No = 39). Compared to spirochetemic Slovenian EM patients infected with , US patients with a positive blood culture significantly less often recalled a preceding tick bite at the site of the EM skin lesion, had a shorter duration of EM prior to diagnosis and more often had multiple EM lesions, regional lymphadenopathy, constitutional symptoms, an increased ESR value, a low blood lymphocyte count and detectable borrelia antibodies in acute and convalescent phase blood samples. Similar differences were observed when US patients were compared to Slovenian patients with infection, but not all reached statistical significance.

In the present study, patients with a solitary erythema migrans (EM) who had a positive blood culture for either Borrelia afzelii (n = 116) or Borrelia garinii (n = 37) were compared with age- and sex-matched patients who had a negative blood culture, but were culture positive for the corresponding Borrelia species from skin. Collectively, spirochetemic patients significantly more often recalled a tick bite at the site of the EM skin lesion, had a shorter time interval from the bite to the onset of EM, had a shorter duration of the skin lesion prior to diagnosis, and had a smaller EM skin lesion that was more often homogeneous in appearance.

Statins have anti-inflammatory and potentially antimicrobial activity, but whether they have a beneficial effect on the course of infectious diseases is controversial. In this study, we assessed the impact of pre-existing statin use on the course and outcome of Lyme neuroborreliosis manifested as meningoradiculitis (Bannwarth's syndrome). One hundred and twenty three consecutive patients with Bannwarth's syndrome, of whom 18 (14.

The aims of the study were to determine the frequency of borrelial infection in patients with peripheral facial palsy (PFP) and to compare clinical and laboratory characteristics of patients with borrelial PFP and patients with PFP of unknown etiology. Adult patients with PFP who presented at our department between January 2006 and December 2013 qualified for the study if they had undergone lumbar puncture and also been tested for the presence of borrelial IgM and IgG antibodies in serum and cerebrospinal fluid (CSF) in indirect chemiluminescence immunoassay. Patients with PFP who had obvious signs/symptoms indicating a disease other than Lyme borreliosis (LB) were excluded.
