First cases of acute human granulocytic ehrlichiosis in Poland.

The first three cases of acute human granulocytic ehrlichiosis in Poland are described. Blood samples were tested by an indirect immunofluorescence method to detect specific serum antibodies, and the polymerase chain reaction was used to detect ehrlichial DNA. Additionally, peripheral blood smears were examined for the presence of morulae. According to criteria of the Centers for Disease Control and Prevention, all three cases can be classified as confirmed granulocytic ehrlichiosis. Using the criteria recommended by a consensus group, however, two cases can be classified as confirmed granulocytic ehrlichiosis and one case as probable granulocytic ehrlichiosis.

[Chemokines in meningitis of different etiologies].

Chemokines constitute a group of cytokines with strong chemotactic activity towards different populations of leukocytes, playing significant role in the pathogenesis of inflammatory responses. The chemokines of the alpha subfamily act mainly on neutrophiles, while beta subfamily chemokines attract primarily monocytes and lymphocytes. Research conducted within the last few years suggests chemokines to be the main factors responsible for the attraction of leukocytes to the cerebrospinal fluid (CSF) in the course of both bacterial and viral meningitis. In cerebrospinal fluid from patients with meningitis of different etiologies significant concentrations of both alpha and beta chemokines were observed, which tended to decrease after the introduction of the treatment, with the relationship to the clinical improvement. It was also confirmed in in vitro experiments that the chemotactic properties of the inflammatory CSF mainly depend on the presence of chemokines. The most important chemokines in the pathophysiology of the meningitis in humans are probably interleukin 8 (IL-8), monocyte chemoattractant protein (MCP-1) and INF-gamma inducible protein (IP-10). They seem to be responsible for the attraction to the cns of, respectively, neutrophiles, monocytes and activated T lymphocytes. Differences between the chemokine profiles observed in meningitides of different etiologies are to some degree relevant to coexisting differences in type and extent of pleocytosis. In future, measurements of concentrations of certain chemokines may become of some importance in diagnostics of meningitis and monitoring its clinical course.

[Incidence of antibody detection against Toxocara canis and clinical symptoms in inhabitants of North-Eastern Poland].

The purpose of this work was to evaluate the the level of exposition of humans on Toxocara eggs in North Eastern Poland on a base of serological tests and epidemiological and clinical data. 1025 inhabitants of North Eastern region of Poland were examine to detect antibodies against Toxocara antigens. 214 (20.7%) showed presence of antibodies against Toxocara. They were mostly males (71%) and country inhabitants (58.9%). No abnormalities in laboratory tests were found among these people. Some of them had complaints like joint pains (19.6%), temporary skin rash 2.3%).

[Tumor necrosis factor alpha and interleukin 1-beta in serum of patients with tick-borne encephalitis].

The purpose of this work was to evaluate the changes of IL-1 beta and TNF-alpha serum concentrations among patients with TBE (tick-borne encephalitis) of mild and severe clinical course. The detection of cytokines was performed by immunometric assay twice before and after treatment. There was no significant changes in IL-1 beta serum concentration after treatment in both groups of patients. But concentration of TNF-alpha decreased significantly after treatment in both groups of patients. It seems that changes of TNF-alpha concentration might be helpful in evaluation of efficacy of aseptic central nervous system treatment.

[Actual diagnostic possibilities of Lyme borreliosis].

Recognising of Lyme disease is based on epidemiology investigation, clinical manifestation of disease and results of diagnostic laboratory tests. Direct methods as isolation and culturing of Borrelia burgdorferi are very difficult and expensive. Depends on clinical stage PCR could be very useful but not often used. The other methods are based on detection of specific antispirochaetal antibodies produced in compartments or detection of antigens B. burgdorferi.

[Selected aspects of immunopathogenesis in Lyme disease].

Abilities of B. burgdorferi to infect and induce illness is connected with immunopathogenic factors as: immunomodulatory elements of tick saliva abilities of B. burgdorferi to move in extracellular matrix, connecting and activation of proteolitic zymogen, inducing endothelium to production of adhesive molecules, chemokines and acute phase proteins. Important elements in pathogenesis and course of Lyme disease are organ tropism, producing by lymphocytes T proinflammatory cytokines (Th1 and Th2 profile), phagocytic abilities of infected organisms. In pathogenesis of chronic and recurrent cases difficult to treat is essential is survive of metabolic inactive bacteria, antigens B. burgdorferi as form "blebs", cystic L-form or insoluble complexes antigen-antibody or possibility of intracellular survive of B. burgdorferi. Tissue and organs damage is caused not only directly by B. burgdorferi antigens. Undoubtedly in the late stages there are immunologic disregulation and molecular mimicry. In some cases important are concommitant other infections. All this factors and results of therapy have influence on prognosis of Lyme disease. Knowledge of pathogenesis of Lyme disease has an important meaning in interpretation of laboratory tests and estimation of clinical signs and choosing of treatment.

[Neurologic syndromes in Lyme disease].

Lyme borreliosis, multisystem disease, when involve neurologic system is named neuroborrelosis. Symptomatology of neuroborreliosis is rich and various. Difficulties in recognition are connected usually with long period from tick bite to late neurological signs. Any headache and psychiatric disorder in the course of Lyme disease could be an early manifestation of invasion of the CNS by the spirochaetes. Each part of neurologic system could be involved. The most common clinical picture of neuroborreliosis is meningitis with cranial or peripheral neuropathies connected with radiculalgia, less common are encephalitis and myelitis, neuropathies and polyneuropathies, encephalopathies. Encephalomyelitis is the most serious form of neuroborreliosis. From the pathophysiologic point of view all cranial and peripheral neuropathies are forms of mononeuritis multiplex. Vasculitis and autoimmunology processes are present. Encephalopathy is due to neuroimmunomodulators, like lymphokines and by toxico-metabolic effect could be connected with each form of systemic borreliosis. Spheroplast L-form of borrelia could be responsible for difficulties with their eradication. Diagnosis of neuroborreliosis is based on culturing of B. burgdorferi from CSF, detection of specific antispirochaetal antibodies produced in subarachnoid space, detection of activated lymphocytes, other antigens detection in CSF (also after dissociation of complexes) or borrelial DNA sequences.

[Bactericidal properties of neutrophils from peripheral blood (PMN)of patients with Lyme borreliosis].

In recent years in Poland, the interest has increased in studies about tick borne diseases, mainly Lyme borreliosis. Immune response and genotype of pathogen play an important role in the course of this disease. Phagocytic cells, especially PMN are dominant in defence mechanisms against bacterial infections. The main feature of PMN is their ability to destroy pathogenic microorganisms by phagocytosis. The aim of this study was to estimate the phagocytic activity of PMN connected with intracellular respiratory burst in patients with Lyme borreliosis. The PMN activity tests completed were: phagocytosis, spontaneous and reduced of nitrotetralizate blue test (NBT). Decreased phagocytic activity and oxygen metabolism of PMN from patients with borreliosis in comparison with values of controls were found. Normalization of these parameters after treatment was observed. Changed phagocytic activity connected with intracellular oxygen metabolism during the course of therapy was the main observation. Depression of phagocytic activity of PMN connected with oxygen metabolism can influence defence reactions in patients with Lyme borreliosis. It is suggested that changes observed are acquired and associated with Borrelia burgdorferi presence.

[Evaluation of FcR and CR receptor expression in granulocytes and immune complex level in patients with tick-borne encephalitis (TBE)].

The aim of this study was to estimate expression of FcR and CR membrane receptors of PMN and circulating immune complexes level in serum from infected patients before and after treatment. Before treatment we observed significant decrease of PMN percentage with FcR and CR receptors in comparison to control. After treatment there was increase of PMN percentage with receptors in comparison to values before treatment but it did not reach values of controls. Immune complexes level before treatment was significant higher than controls before treatment and it decreased after treatment but did not reach control level. Depression of phagocytic activity of PMN may be one of the main reasons for spreading viral infection.

Analysis of some peripheral blood lymphocyte subsets in relation to Borrelia burgdorferi antibodies in patients with Lyme disease.

The aim of our study was to evaluate the changes in T (CD3), B(CD19) lymphocytes, CD4 and CD8 subsets, activated CD3+ HLA-DR+ lymphocytes, lymphocytes with receptor for IL-2 (CD3+CD25), NK cells as well as the rate of CD4/CD8 in 30 patients with recognized Lyme disease, before and after antibiotic therapy. Patients were divided into the following groups: Group I n = 9--without detected specific antibodies against B. burgdorferi and with clinical recognition of EM(erythema migrans). Group II n = 10--with increased IgM production, with a clinical form of Lyme arthritis and neuroborreliosis. Group III n = 11--with increased IgG anti B. burgdorferi production, with clinical recognition of Lyme arthritis. The results were compared with the results obtained in the control group consisting of 90 healthy people. The measurements were performed in the flow cytometer COULTER EPI XL with Becton Dickinson antibodies. The antibodies against B. burgdorferi were detected by means of ELISA method using Dako, Biomedica and Biocom kits. The statistic analysis was performed with AnStat Program. The changes in lymphocyte subsets were characterised by the decrease in the percentage of CD4, CD8, NK and CD3+HLA-DR+ lymphocytes in peripheral blood before treatment with later tendency to increase. The results show that the lag phase of antibodies production coincides with high activity of lymphocytes (group I). The significant level of antibodies in IgM class induced by the collaboration of T and B cells was found in the group II. In the group III, in which antibodies in IgG class predominated, the changes in lymphocyte subsets were less intensive. The results of our investigations indicate that the immune response in Lyme disease develops mainly with the participation of both cellular and humoral response which is involved in both the defense against and the pathogenesis of the disease.

[Selected lymphocyte subsets in Lime borreliosis: a preliminary study].

Observation of percentages changes of lymphocytes (CD19), T(CD3), subsets CD4, CD8, NK cells, activated lymphocytes with fenotype CD3+HLA-DR, CD4/CD8 rate in Lyme borreliosis was carried out before (I examination) and after antibioticotherapy (II examination). 30 patients in aged 17-60 (x = 41) with recognition of erythema migrans(EM), Lyme arthritis(LA) and neuroborreliosis(NB) were examined. Epidemiological, clinical diagnosis was confirm by the presence of antibodies in ELISA test. Lymphocytes and their subsets, NK cells were signed and measured by flow cytometric immunophenotyping in Coulter EPIX XL with Becton-Dickinson antibodies twice: before and after treatment. Ampicillin, ceftriaxon or cefotaxim was applied during 4 weeks. AnStat program was used in statistic analysis. Value CD3 (x = 72.54) in I test was higher than control (x = 69.3), but CD19 (x = 13.2) was lower than control (x = 12.9). In II examination we stated CD19 (x = 9.48) progressive significant decreased in comparison to I examination. Percentage CD4 in II examination (x = 42) was lower than control (x = 45.8). Subset of CD8 had lower value in I examination (x = 28.03), as in II (x = 30.72) in comparison with control (x = 34.2). We showed lower CD4/CD8 (x = 1.40) rate after treatment than control (x = 2.67). We showed lower percentage NK cells after treatment (x = 13.5) than control. We also found lower percentage activated subsets T cells with phenotype CD3+HLA-DR before (x = 4.78) and after treatment (x = 4.03) compared with control (x = 7.27). No statistical changes in subsets with receptor for IL-2 before and after treatment was shown. In the course of active infection B.burgdorferi essential changes in lymphocytes subsets are observed. Decreased percentages of CD4, CD8, NK and CD3+HLA-DR+ in whole blood indicate their important role in immunopathogenesis of Lyme borreliosis. Lack of normalization of investigated parameters after treatment can be caused by inertion of elements immunologic system, as well as too short antibioticotherapies.

[Herpes simplex encephalitis].

Herpes simplex virus infection of the central nervous system is still a significant cause of morbidity and often mortality. Changes of central nervous system are results of primary infection or activation of latent HSV-1, HSV-2. Neurological deficits often follow encephalitis herpetica. The application of PCR is prompt and specific diagnosis of herpes simplex virus infections of the brain. Advances in treatment herpes simplex encephalitis with acyclovir have improved outcome.

[Lyme disease vaccine: hopes and concerns].

The vaccine against Lyme disease for last decade became an important issue for many researchers. Recently two groups of scientists published data of their trials carried out on humans. The vaccine which was given to volunteers consisted of recombinant outer surface protein (Osp)A. These people were observed for two years when approximately 79% of them developed resistance to Borrelia burgdorferi infection. These data were evaluated by FDA experts who recommended vaccine for approval. Main concerns of experts are: short duration of observation of vaccinated people, no possibility to vaccinate children, problematic vaccination people with undiagnosed Lyme disease. However the moment when effective and safe vaccine against Lyme disease will be available seems to approach.

[Prevention of Lyme disease].

Over the last decade many researchers have turned much attention to the vaccine against Lyme disease as the only effective preventive method. Recently two groups of researchers have published data on their trials carried out on humans. The vaccine given to volunteers consisted of recombinant outer surface protein (Osp)A. A two-year observation of the persons studies revealed that 79% of them had developed resistance to Borrelia burgdorferi infection. These data were evaluated by the FDA experts who recommended the vaccine for general use with the following reservations that have to be elucidated: too short observation of vaccinated persons, no possibility to vaccinate children and the problem of vaccinating people with undiagnosed Lyme disease.

[Levels of proinflammatory cytokines: IL-1, IL-6, IL-8, TNF-alpha and receptor IL-6R in Lyme borreliosis].

We estimated serum concentrations of cytokines IL-1, IL-6, IL-8, TNF-alfa and IL-6R of patients with diagnosed Lyme disease treated with beta-lactam antibiotics. Detection of proinflammatory cytokines was performed in ELISA tests. The examination was performed before and after treatment. Comparison with control group stated statistically significant higher concentration of IL-1 and IL-6 before and after treatment. There were no differences in concentration of TNF-alfa, IL-8 and IL-6R. Comparing concentrations of cytokines before and after treatment there was no differences either. Lack of changes in concentration of proinflammatory cytokines during beta-lactam therapy could be explained by too short period of therapy or immunologic background of inflammatory process in Lyme disease which was only initiated by spirochete Borrelia burgdorferi.

[Concentrations of tumor necrosis factor alpha and interleukin-1 beta in cerebrospinal fluid in the course of tick-borne encephalitis].

CSF concentrations of TNF-alpha and Il-1 beta were detected in patients with TBE. The cytokines were detected by immunometric assay by MEDGENIX kit. CSF Concentrations of TNF-alpha and IL-1 beta in patients with TBE were significantly higher than in control group before as well as after treatment and normalization of CSF parameters. These concentrations were lower comparing to one obtained in group of bacterial meningitis. There was no correlation between concentration of cytokines and other CSF parameters (cytosis, protein, glucose concentration). Concentrations of analysed cytokines did not change significantly before and after treatment. Detection of CSF concentrations of TNF-alpha and Il-1 beta in patients with tick-borne encephalitis can be used to evaluate efficacy of treatment and retreat of infection.
