A prospective study was carried out on 31 healthy individuals and 32 patients with rheumatoid arthritis at the Military Hospital N0 103 and the Enterology Department of the Police Hospital N0 198. The results showed that: in the patient group, there were increases of number of white blood cells, and lymphocytes, as compared to the control group (p<0.001); there was also wide fluctuation of tumor necrosis factor (TNF-), from 22.41 pg/ml to 1341.62pg/ml. 75% patients had concentration of rheumatoid factor RF≥8 IU/ml (positive). There were agreeable correlations between the number of lymphocytes T, Ta with lymphocytes B at rate r=0.64 (p<0.05); between the number and percentage of Ta-cell with serum concentration of rheumatoid factor (RF) in the patients at low level of r=0.24 and r=0.33

The nature of immunoresponse is to protect of body from antigens, but excessive immunoresponse leads harmful and serious effects for body. The communosuppressive drugs were effective in the treatment of patients with renal transplantation, primary nephritic syndrome and pyelonephritis. However, the drugs cause many side and adverse effects such as infection. It should monitor clinical manifestations and examine periodical blood during the treatment to reduce the dose or interruption of the treatment.

20 patients with glomerular nephritis received a biopsy through the skin to study the histological lesion by photomicroscopy and the direct fluorescent immune including the electromicroscopic immune and super structure for some cases. Some lesion were classified by the photomicroscopy comprise the minimal lesion glomerular disease (46%), the glomerular nephritis with intervascular proliferation (35%); glomerular nephritis with membrane proliferation with reduction or increase of crescent cells (15%). The results of comparison of the photomicroscope with the direct fluorescent immune found 1 patient with the glomerular nephritis IgA. In addition to, there is a deposition of IgG, IgM and IgA accompanied with C19 and/or C3c in the basal membrane of the glomerular and membrane Bowman. These showed that pathology of glomerular has an immunopathological mechanism. The deposition of the immunological complexes in the glomerular helped the prognosis of the clinical correspond of old patients to the treatment

New information regarding the molecular mechanisms of allergic disorders has led to a variety of novel therapeutic approaches. This article briefly reviews the pathogenesis of asthma and allergic diseases, discusses the rationale behind using immunomodulators in these diseases; and examines the therapeutic effects of immunomodulators on allergic diseases. There are a number of immunomodulators that have been developed for the treatment of allergic disorders. Some have looked very promising in pre-clinical trials, but have not shown significant benefits in human clinical trials thus indicating the disparity between mouse models and human asthma. This review focuses on immunomodulators that are in human clinical trials and not molecules in pre-clinical development.

Sepsis is defined as the presence of pathogenic microorganisms or their toxins in tissues or in the blood. It can be accompanied by multi-organ failure and can potentially lead to death if not treated properly. The pathogenesis of sepsis is related not only to the activation of inflammatory pathways but also to an immunodepressed state. The modulation of the host response to infection has been studied as an adjunctive therapeutic approach in many preclinical investigations and clinical trials. However, there are several limitations of immunomodulators currently in use for those studies. A review of the major clinical trials of immunomodulatory therapies in sepsis provides a perspective on the reasons why such approaches have failed to show benefits. Above all, the criteria for patient inclusion have not considered the timing of administration of immunomodulators, the infected organisms, the site of infections, and the monitoring of immune competence. These might have contributed to the negative results of clinical trials conducted thus far. Therefore, future studies addressing these factors may demonstrate a beneficial role of immunomodulatory therapies in well-defined groups of patients with severe infection.

T cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibition motif domain (TIGIT) is a newly discovered immune checkpoint molecule, mainly expressed on the surface of T cells and natural killer (NK) cells. By binding to cluster of differentiation 155 (CD155) and other ligands, it inhibits T cell and NK cell-mediated immune responses and affects the tumor microenvironment. Multiple preclinical studies have demonstrated that the TIGIT/CD155 pathway plays a role in a variety of solid and hematological tumors. Clinical trials investigating TIGIT inhibitors alone or in combination with programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors for lung cancer are currently underway.

Within the wide-ranging gamut of factors that comprise gene-environment interactions postulated to underlie schizophrenia, the crosstalk between environmental factors and feto-maternal immune components has been put forth as one of the important mechanisms that increase the risk towards schizophrenia in the offspring. Interestingly, immune factors have been shown to critically modulate the brain development during the prenatal stages. Moreover the past many decades, influential theoretical propositions and evidence base (albeit not unequivocally) have compellingly linked prenatal sex hormonal status to critically provoke long lasting immunological changes and subsequently affect developmental programming of cerebral asymmetry in schizophrenia. In this review, we summarize the select perspectives emphasizing the role of neuroimmunoendocrine pathways in anomalous cerebral asymmetry in contemporary understanding of schizophrenia pathogenesis.

OBJECTIVE: There has been no study in the literature evaluating total blood count in obsessive-compulsive disorder (OCD). Therefore, we performed the present study to spesifically measure serum total blood count particularly white blood cells to see whether or not its eventual alterations might have an etiopathogenetic significance in patients with OCD. METHODS: Total blood count was measured in thirty patients and same number of healthy controls. Additionally, all patients were assessed by Yale-Brown Obsession Compulsion Scale (Y-BOCS). RESULTS: Except for neutrophil count, there were no significant differences between the groups regarding any haematological parameter. The mean neutrophil count of the patient group was lower compared to that of the control subjects. CONCLUSION: In conclusion, the present study suggests that neutrophil count is reduced in pure OCD patients and this finding may contribute to the role of immunological factors in the pathogenesis of OCD.

Immunomodulatory drug lenalidomide is a synthetic compound derived by modifying the chemical structure of thalidomide to improve its potency and reduce its side effects. Lenalidomide is a 4-amino-glutamyl analogue of thalidomide that has emerged as a drug with activity against various hematological and solid malignancies. It is approved by FDA in USA for clinical use in myelodysplastic syndromes with deletion of chromosome 5q and multiple myeloma. Studies have shown that lenalidomide exert anti-tumor activity probably by various mechanisms in hematologic malignancies, such as immunomodulation, anti-angiogenesis and effects on signal transduction. In this article, the progresses of study on these problems are reviewed.
