Interleukin 6 Receptor

We investigated the serum concentrations of interleukin-6 (IL-6) and two IL-6 family of cytokines (leukaemia inhibitory factor (LIF) and ciliary neurotrophic factor (CNTF) as well as IL-6 soluble receptor (sIL-6R) using an enzyme-linked immunosorbent assay (ELISA) in 66 patients with rheumatoid arthritis (RA) and 24 healthy controls. We examined a possible association between the serum levels of these peptides and RA activity according to the Mallya and Mace scoring system and Ritchie's index. We also evaluated the correlation between the serum levels of IL-6, LIF, CNTF and sIL-6R and duration of the disease and calculated sIL-6R/IL-6 ratio in RA patients and in the control group. IL-6 and sIL-6R were detectable in all 66 patients with RA and 24 normal individuals. LIF was also found in the serum of all patients with RA and in 16 (66.7%) normal individuals. In contrast CNTF was measurable only in 15 (22.7%) patients with RA and 24 (33.3%) normal individuals. The highest IL-6 and sIL-6R levels were found in the patients with Stages 3 and 4 of RA activity and the lowest in the control group. In contrast there were no statistically significant diferences between the LIF and CNTF levels in RA patients and normal individuals. We found positive correlation between IL-6 and sIL-6R concentrations and Ritchie's index and a lack of such correlation with LIF and CNTF. IL-6 serum level correlated positively with the disease duration, but sIL-6R, LIF and CNTF did not. Serum sIL-6R/IL-6 ratio was significantly lower in RA patients than in healthy controls. In conclusion, an increase in the serum levels of IL-6 and sIL-6R, but not LIF and CNTF concentrations, may be useful markers for RA activity.

SummarySoluble Interleukin-6 receptor (sIL-6R) levels are strongly related to the levels of Interleukin-6 (IL-6), and sIL-6Rs increase the immune activating properties of IL-6. We estimated sIL-6R serum levels in 25 schizophrenic patients and 25 healthy controls. In the patients, SIL-6R-CSF levels were also measured. The psychopathology was rated according to the AMDP system. We found a significant correlation between serum and cerebrospinal fluid (CSF) levels of sIL-6R, suggesting that serum levels may be a meaningful marker for the central action of sIL-6R. Moreover, significant correlations between the paranoid-hallucinatory syndrome and sIL-6R levels both in serum and CSF were observed. This finding suggests that IL-6 plays a role in the paranoid-hallucinatory symptomatology in schizophrenia. This can be understood regarding the influence of IL-6 to the catecholaminergic neurotransmission. The downregulating effects of neuroleptic treatment to sIL-6R demonstrate that the sIL-6R levels are decreased in the whole group of schizophrenic patients compared to controls.

Introduction. Fucosylation of acute phase proteins and serum soluble selectin levels is increased in rheumatoid arthritis (RA) patients and can influence leukocyte extravasation. Aim. The aim of this study was to evaluate the concentration and fucosylation of ?1-antichymotrypsin (ACT) in relation to serum concentrations of soluble forms of selectins in RA patients. Material and methods. Serum samples of 70 RA patients and 30 healthy controls were examined using sandwich enzyme-linked immunosorbent assay (ELISA). Results. ACT-FR was significantly increased in RA patients when compared to healthy controls (p < 0.001) and significantly correlated with serum concentrations of rheumatoid factor (RF) and antibodies against cyclic citrullinated peptides (ACPA) (p = 0.006, p = 0.04, respectively). Moreover, we found significant correlations between the serum levels of soluble (s)P- and sE-selectin and ACT-FR (p = 0.008 and p = 0.03, respectively) only in male RA patients.Conclusions. Fucosylation of ACT differs between male and female RA patients and is related to sP- and sE-selectin levels only in men.

Aim. To establish the pathogenic value of serum cytokine (interleukin-6 and interleukin-8) production in patients with candidal vulvovaginitis to optimize diagnostic and therapeutic approaches. Methods. 74 adolescent girls suffering from candidal vulvovaginitis aged from 12 to 19 years were examined. The diagnosis of candidal vulvovaginitis was verified according to the international classification of World Health Organization (ICD-X codes B37.3 and N77.1). At the stage of clinical examination, medical and general history was analyzed, general and gynecological examination was performed. The diagnosis of candidiasis was confirmed by the presence of vegetative forms of Candida spp. (budding yeast cells, pseudomycelium and/or mycelium) in Gram-stained smears from the mucous membranes of the vulva, urethra. The control group consisted of 20 healthy patients of appropriate age and sex. Serum levels of interleukin-6 and interleukin-8 were measured by enzyme-linked immunosorbent assay using «ELISA interleukin-6» and «ELISA interleukin-8» test systems (ZAO «Vector-Best», Russia). Results. The study has shown increased serum levels of interleukin-6 in adolescent patients with candidal vulvovaginitis. Interleukin-6 level in peripheral blood was significantly higher in patients with candidal vulvovaginitis (21.7±2.4 pg/ml) compared to controls (9.4±1.5 pg/ml, p 0.02). Serum interleukin-8 level was also significantly higher (51.2±2.1 pg/ml) in patients with candidal vulvovaginitis compared to controls (23.9±1.04 pg/ml, p 0.01). Conclusion. The revealed features of interleukin-6 and interleukin-8 production may be used as additional objective criteria of the orientation of the inflammatory response in patients with various forms of vaginal candidiasis. The changes of the studied parameters might reflect the state of the immune system and the severity of the inflammatory response.

Rheumatoid arthritis (RA) is one of the chronic inflammatory autoimmune diseases which occurs as a result of unknown reasons. This study was conducted at Baghdad Teaching Hospital/City of Medicine, where blood samples were taken from 60 Iraqi patients with RA (49 females and 11 males) and these patients were matched by age and sex with 20 healthy controls (16 females and 4 males). Patients with RA were diagnosed by a consultant rheumatologist according to ACR / EULAR criteria in 2010. In this study the patients were divided into four groups as follows; the first group consisted of 12 patients treated with methotrexate (MTX), the second group consisted of 10 patients treated with etanercept, the third group consisted of 18 patients treated with a combination of MTX, etanercept and prednisolone, the fourth group consisted of 20 patients treated with MTX and etanercept. Enzyme linked immunosorbent assay (ELISA) was used to detect CCL18/PARC antibodies, while a spectrophotometer (Humalyzer2000) was used for the measurement of alkaline phosphatase (ALP). Serum levels of CCL18 / PARC showed a significant increase in RA patients compared with healthy controls (p ≤ 0.001). The levels of CCL18/PARC showed a significant correlation with disease activity (CDAI), except in RA patients treated with etanercept. There was also no significant correlation between CCL18/PARC and erythrocyte sedimentation rate (ESR). The results showed a significant increase in serum levels of alkaline phosphatase (ALP) was recorded in RA patients (with treatment) as compared to healthy controls (p ≤ 0.001).

We investigated the serum concentration of total metalloproteinase-9 (tMPP-9), active MMP-9 (aMMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) in a group of 41 patients with SLE and 20 healthy controls. Serum levels of tMMP-9 and TIMP-1 were assessed by an enzyme-linked immunosorbent assay (ELISA) and aMMP-9 by fluorometric assay. The tMMP-9 level was lower in SLE patients (mean 262 ng/mL) than in healthy volunteers (mean 325 ng/mL) (P=.048). Similarly, aMMP-9 level was lower in SLE patients (mean 121 ng/mL) than in control group (mean 169 ng/mL) (P=.0355) and lower in active SLE (mean 54 ng/mL) than in inactive disease (mean 99 ng/mL) (P=.033). TIMP-1 level was also lower in SLE patients (mean 181 ng/mL) than in control group (mean 233 ng/mL) (P=.004). In SLE patients, a positive correlation was found between tMMP-9 and aMMP-9 (ρ=0.568;P=.001). We also found a positive correlation of tMMP-9 and TIMP-1 with VEGF concentrations (ρ=0.450,P=.005andρ=0.387;P=.018, resp). tMMP-9, aMMP-9, and TIMP-1 serum levels are lower in SLE patients than in healthy control group.

ABSTRACT Background: Migraine is a multifactorial neurovascular syndrome and closely associated to inflammation. Cystatin C (Cys C) is a neuroendocrine polypeptide which also plays a role in inflammation. Objective: To investigate the levels of Cys C in migraine patients without aura. Methods: A total of 80 participants were included in the study; 40 patients and 40 healthy controls. Serum Cys C levels were investigated by using enzyme-linked immunosorbent assay (ELISA). Statistical analysis were performed using Statistical Package for the Social Sciences (SPSS) version 22.0 (SPSS Inc, IL, USA). Results: Serum Cys C levels were found as 73.88 ng/mL in the patient group and 24.92 ng/mL in the healthy control group, being significantly higher among patients (p=0.000). Serum Cys C levels were significacntly different across age subgroups among patients (p=0.049), but not among controls. However, visual analog scale (VAS) (p=0.707), disease duration time (p=0.725) and body mass index (p=0.136) were not significantly different between the two groups. Conclusion: Our findings demonstrate that high serum Cys C levels are independently associated to migraine without aura. To the best of our knowledge, this is the first study to determine the serum levels of Cys C in patients with migraine. Thus, serum Cys C may be a potential biomarker of migraine.

Cell Chronic Lymphocytic Leukemia

We have investigated the serum concentrations of interleukin-6 (IL-6) and two IL-6 family cytokines-oncostatin M (OSM) and leukemia inhibitory factor (LIF)-in 63 patients with B-cell chronic lymphocytic leukemia (B-CLL) and 17 healthy controls using the enzyme-linked immunosorbent assay (ELISA) method. Simultaneously, we measured the serum levels of the soluble forms of two subunits of the IL-6 receptor complex-ligand binding glycoprotein 80 (sIL-6R) and glycoprotein 130 (sgp130). The cytokines and receptors were evaluated in 25 untreated patients and 38 patients treated with cladribine (2-CdA), as well as in 17 healthy controls. We have correlated the serum levels of these proteins with Rai's clinical stage of the disease, the response to 2-CdA treatment and some hematological parameters. We have also evaluated the correlation of the IL-6 serum level with the concentration of OSM and IL-6 soluble receptors. IL-6 was measurable in 62/63 (98.4%), OSM in 20/25 (80%) of untreated and 14/38 (37.8%) of the treated patients. sIL-6R and sgp130 were detectable in all 63 patients and LIF in none of the CLL patients. IL-6 serum level in untreated patients was not significantly different as compared to its concentration in the control group (P>0.05). However, in the patients treated with 2-CdA the IL-6 level was significantly lower (P<0.02), and the lowest concentration was found in the patients with complete remission (CR; median 1.4 pg/ml; P<0.02). The concentration of sIL-6R was significantly higher in untreated (median 61.8 ng/ml) and treated (median 50.1 ng/ml) CLL patients when compared to normal persons (median 41.2 ng/ml; P=0.04; P<0.001, respectively). There was no difference between the sIL-6R levels in the patients with CR and the healthy controls. In non-responders sIL-6R concentration was the highest and similar to its level in the untreated patients. OSM level was higher in the untreated patients (median 1.8 pg/ml) than in the normal controls (median 0.0 pg/ml; P<0.001) and in the CR patients (median 0.0 pg/ml; P<0.03). The serum concentration of sgp130 was similar in the untreated (median 480 pg/ml) and treated (median 470 pg/ml) patients, as well as in the healthy persons (median 420 pg/ml; P>0.05). We have found significant positive correlation between the levels of sIL6R and the lymphocytes count in CLL patients (Ρ=0.423; P<0.001). In addition, sIL-6R and OSM serum concentrations correlated also with CLL Rai stage. In conclusion, the serum level of IL-6, OSM and sIL-6R, but not LIF and sgp130, are useful indicators of CLL activity.
