Study of some cytokines in patients with brucellosis in Najaf province

Abstract

Background: To evaluate the levels of pro-inflammatory cytokines for ‘Th1/Th2 brucellosis’ patients serum to determine ‘antimicrobial susceptibilities’ of Brucella strains. Methodology: The study comprised 35 individuals with acute brucellosis, and 21 patients with chronic brucellosis, identified clinically. A group of 20 healthy adult persons was also enrolled in the study. For all of the participants, blood cultures and standard tube agglutination tests for Brucella were performed. ELISA was used to detect cytokine levels in serum samples collected following the treatment period and detect Brucella strains celebrated from different sites of infection, and in order to find-out the susceptibilities against antibiotics including rifampicin (RIF), streptomycin (STR), doxycycline (DOX), and ciprofloxacin (CIP) via the gradient strip (E test). Results: The patients included 22 (39.29 percent) males and 34 (60.71 percent) females based on their gender and age. Fever was the most common clinical feature (92%), sweating came in second place (75%), followed by back pain with 18%. Patients with brucellosis had substantially higher blood levels of interleukin-6 (IL-6), interferon (IFN), and tumor necrosis factor-alpha (TNF-alpha) analogous to the control group (P = 0.05). IL-4 and IL-2 levels between the sick and control groups did not vary significantly. The amounts of these cytokines were found to be identical in acute and chronic individuals. Rendering to "minimum inhibitory concentrations (MIC) 90 levels," CIP was determined to be the most effective antibiotic. Then followed DOX and then STR, correspondingly. All of the samples were CIP and DOX susceptible; 18 (23.2%) strains were discovered to be only mildly sensitive to RIF, with MIC50 and MIC90 maximal values. Conclusions: Our findings point to an important role for IFN and proinflammatory cytokines in brucellosis pathogenesis. However, these changes were shown to be unrelated to the severity or activity of the illness. Furthermore, all strains were identified as Brucella strains. ciprofloxacin, doxycycline, rifampicin and streptomycin were found to be effective for the treatment of brucellosis.
