A Novel Rapid IL-6 Release Assay Using Blood Mononuclear Cells in the Differential Diagnostics of Patients after Skin Localized Hypersensitivity Reactions to Drugs | Chapter 10 | Perspective of Recent Advances in Medical Research Vol. 10

 Interleukin-6 (IL-6) has a main role in the musical arrangement of immune response. It is showed to have a key role in the change from innate to adjusting immune reaction. It has two together pro and antagonistic-inflammatory features. Normal values in antitoxin are below 7 pg/ml. Its effects are mostly dependent on the demeanor of its receptor (IL-6R) that is bound either on the cell surface or exists in free dissolved form (sIL-6R). The binding of a small microscopic weight fragment (i.e a drug) to its receptor and to HLA fragments on T-memory containers does not involve certainly hapten presentation but can proceed very immediately by pharmacologic interaction (p-i) mobilizing immune means (Pichler). This in turn can mobilize pro-inflammatory means and start through the IL-6 release a response order both artificial and in vivo. Our aim was to measure secreted IL-6 from the mononuclear containers’ supernatants after 20 proceedings incubation in a big cohort of patients following in position or time both of early and late skin sensitivity (HS) reactions to differing common drugs (43) arising from the record and compare the results accompanying those of an appropriate control group and validate bureaucracy by in vivo tests. Together 213 patients accompanying the history of adverse belongings to drugs and 48 control subjects were complicated. The majority of cases (159) and all the controls’ mononuclear cells were divided and after readiness with a standard order of 0.15-0.5 µmol solutions of various drugs for 20’ in addition to negative and positive controls, IL-6 announced into the cell free supernatants was calculated by ELISA assay. The tests were correlated to the former diagnostic method expanded to measure nuclear rearrangements afterwards similarly short development with drugs named chromatin incitement test. The exact conditions unavoidable for reproducible and clinically relevant results were settled by comparing two groups of similar dispassionate phenotype composition. The form offering extreme sensitivity was selected out.   Sensitivity of 85.4% and particularity of 82.4% of the IL-6 release assay was found against the in vivo tests. In the microscopic mass range of 76-4000 Da, IL-6 release was helpless on the clinical phenotype but gone the evoking drug(s). Reactivity of mononuclear cells at rude or at multiple drug test concentrations mirrored clinical asperity per diagnoses, or in HS cases with varying skin difficulty the area, complicated. The largest pharmacological subgroup provoking positive test results was of nonsteroidal anti-angering drugs (NSAID). Consisting of 51 patients and 9 controls, individually was tested by 9 various non-steroidal anti-inflammatory drugs and distinguished with another group of subjects (56 with next or early HS reaction in their record) using determination of particular IgE against NSAID from their sera within individual year following in position or time the event. In vivo tests (patch, intradermal and oral provocations) were acted in parallel to artificial testing. The zeal ratio of validated test results was almost double within the IL-6 release-proven group after antagonistic reactions due to NSAID compounds as distinguished to specific IgE proven patients’ positiveness in their sera (65.4% vs. 36.5%). The mechanism of IL-6 transsignaling that is behind the life threatening “Cytokine Release Syndrome” is trusted to account for this novel demonstrative test.
