Cím:A novel rapid (20-minute) IL-6 release assay using blood mononuclear cells of patients with various clinical forms of drug induced skin injuries / Baló-Banga Joseph M., Schweitzer Katalin, Lakatos Susan, Sipka Sándor
Dátum:2015
ISSN:1939-4551
Megjegyzések:Background: IL-6 is a pro-inflammatory cytokine which has many well-defined effects. Its synthesis and release from mononuclear cells of drug-sensitized patients was related before to in vitro drug-allergy diagnostics but has not yet been studied in detail. Methods: The specific release of preformed IL-6 from peripheral blood mononuclear cells (PBMC) after 20 minutes incubation with 0.15?0.5 ?M of pure drugs was measured in two groups of drug-allergy suspected donors (159) and respective controls (48). IL-6, TNF-alpha, IL-2, IL-4, IFN-gamma have been measured from cell supernatants by ELISA or by cytometric bead assay. Epicutaneous, intradermal and systemic provocation tests were performed to prove or disprove culprit substances (203 in vivo against 482 in vitro tests). T-test (paired and unpaired); chi2 contingency table; Z statistics and McNemar's test were used to evaluate results. Results: Concanavalin A as positive control released IL-6 from PBMC in linear concentration and exponential time dependent fashion (up to 60 minutes) pointing to the existence of a preformed pool of this cytokine. Preformed IL-6 released at any of 4 standard drug dilutions tested, above 50% over their diluents' levels significantly correlated with the patients' history on drug-induced hypersensitivity symptoms and with in vivo tests. Sensitivity of 85.4% and specificity of 82.4% of the IL-6 release assay were found. The 20· drop in release of TNF-alpha had no diagnostic importance; it has accompanied increased IL-6 release. IL-2, IL-4 and IFN-gamma were undetectable in 20 minutes supernatants. IL-6 release depended on the clinical phenotype but not on the eliciting drug(s) in the molecular mass range of 76?4000 Da. Reactivity of mononuclear cells at the lowest or at multiple drug test concentrations reflected clinical severity per diagnoses and according to area of skin involvement. Conclusion: This rapid test is applicable to detect a wide scale of drug hypersensitivity

Cím:Association between Serum IL-16 Levels and the Degree of Sensitization in Patients with Atopic Dermatitis / Nagy Georgina, Gáspár Krisztián, Irinyi Beatrix, Gál Mónika, Tumpek Judit, Gyimesi Edit, Sipka Sándor, Remenyik Éva, Szodoray Péter, Szegedi Andrea

Megjegyzések:Background: Interleukin (IL)-16 has been characterized as animmunomodulatory cytokine. Besides its chemotactic properties,IL-16 amplifies inflammatory processes and possessesimmunoregulatory functions. Our aim was to investigate theassociation between serum IL-16 levels and the degree of allergicsensitization in patients with atopic dermatitis (AD).Methods: The serum level of IL-16 was measured by immunoenzymaticassays. Eosinophil cell count, serum total andspecific IgE levels were assessed; prick tests were also carriedout. Based on specific IgE levels and prick tests, AD patientswere divided into sensitized and nonsensitized subgroups,and correlations among serum IL-16, total IgE levels and eosinophilcell counts were measured in the total patient groupand in subgroups. Results: In the total patient group, significantlyhigher levels of IL-16 were found in the sera of patientswith AD, compared to healthy individuals and patientswith psoriasis. A significant correlation was detected betweenserum levels of IL-16 and total IgE, total IgE andeosinophil counts, but not between IL-16 and eosinophils.

Cím:Histamine potentiates human platelet aggregation induced by platelet-activating factor / Sándor Sipka, Mátyás Koltai, Pierre Braquet, Gyula Szegedi
Dátum:1992
Megjegyzések:Using human platelet-rich plasma (PRP) we found that histamine concentration-dependently potentiated platelet aggregation induced by platelet-activating factor (PAF). When added separately, neither histamine nor chloropyramine, a competitive antagonist of H1 receptors, influenced platelet aggregation, however BN 52021, a specific PAF receptor antagonist, concentration-dependently inhibited the response. Chloropyramine reduced the potentiating effect of histamine on PAF-induced platelet aggregation, and when it was coadministered with BN 52021, inducing 63% inhibition of PAF-induced aggregation, the histamine-potentiated PAF response was completely abolished. This observation draws attention to the importance of cooperation between histamine and PAF in mediation of platelet aggregation in human PRP, and points to the powerful antiaggregatory effect of BN 52021 combined with an antagonist of H1 receptors.

Cím:Association between the occurrence of the anticardiolipin IgM and mite allergen-specific IgE antibodies in children with extrinsic type of atopic eczema/dermatitis syndrome / E. Szakos, G. Lakos, M. Aleksza, E. Gyimesi, G. Páll, B. Fodor, J. Hunyadi, E. Sólyom, S. Sipka
Dátum:2004
ISSN:0105-4538
Megjegyzések:AbstractBACKGROUND: As the literature has only controversial data on the role of nonallergen-specific antibodies in atopic eczema dermatitis syndrome, the authors investigated the link between the occurrence of the antiphospholipid [anticardiolipin (ACL), anti-beta2-glycoprotein I] and allergen-specific immunoglobulin E (IgE) antibodies in 72 children with atopic eczema/dermatitis syndrome (AEDS).METHODS: The measurement of antiphospholipid antibodies was carried out by enzyme-linked immunosorbent assay (ELISA), serum total IgE by nephelometry, and allergen-specific IgE by immunoblotting assay. The statistical analysis was carried out by Fisher's exact test and odds ratio was calculated.RESULTS: Thirteen of 72 children with AEDS (mean age 8.3 years) had elevated serum levels of ACL, and eight anti-beta2-glycoprotein I antibodies. The presence of allergen-specific IgE against inhalant allergens and nutritive allergens was among eight of 13 and three of eight in the cases with elevated ACL. The ratio of patients with highly increased severity scoring of atopic dermatitis (SCORAD) index (>75) was significantly higher in the group with elevated (4/13) than in those with the normal ACL levels (2/59). There was a significant association between the appearance of mite (Dermatophagoides pteronyssinus, D. farinae)-specific IgE and ACL IgM antibodies (6/13).CONCLUSION: These findings show that there are significant linkage and association between the appearance of ACL IgM or the production of allergen-specific IgE against inhalant (mainly mite) allergens in children with atopic eczema/dermatitis syndrome.

Cím:Anti-citrullinated protein antibodies in rheumatoid arthritis : as good as it gets? / Szekanecz, Z., Soos, L., Szabo, Z., Fekete, A., Kapitany, A., Vegvari, A., Sipka, S., Szucs, G., Szanto, S., Lakos, G.
Dátum:2008
ISSN:1080-0549 (Print)
Megjegyzések:Anti-citrullinated protein antibodies (ACPAs) have recently emerged as sensitive and specific serological markers of rheumatoid arthritis (RA), providing superior alternative of the rheumatoid factor (RF) test in the laboratory diagnostics of RA. The first members of this autoantibody family were anti-perinuclear factor (APF) and anti-keratin antibodies (AKA). It became evident that both APF and AKA recognize citrullinated epitopes of filaggrin. Citrullination is a post-translational modification of arginine by deimination, physiologically occurring during apoptosis, inflammation or keratinization. The presence of several citrullinated proteins has been demonstrated in the RA synovium. The identification of citrullinated epitopes as targets for anti-filaggrin antibodies led to the development of the first and later second generation anti-cyclic citrullinated peptide (anti-CCP) antibody assays. The widely used anti-CCP2 assays have high diagnostic sensitivity and specificity, and they also show important predictive and prognostic value in RA. The anti-Sa antibody has been identified a decade ago; however, recent studies confirmed that anti-Sa is directed against citrullinated vimentin, hence it is a new member of the family of ACPAs. The newly developed anti-mutated citrullinated vimentin (anti-MCV) assay has similar diagnostic performance than the anti-CCP2 ELISA; however, the diagnostic spectrum of the anti-MCV test is somewhat different from that of anti-CCP2. It's especially useful in the diagnosis of RA in RF and anti-CCP2 seronegative patients. The combined application of anti-CCP2 and anti-MCV assays can improve the laboratory diagnostics of RA. The family of ACPAs is expected to expand; there is an increasing need for developing new diagnostic strategies after careful evaluation of the characteristics of the available assays.
