Background Digestion of collagen with clostridial collagenase (CC) produces peptides that can induce cellular responses consistent with wound healing in vivo. However, nonhealing human wounds are typically in a state of chronic inflammation. We evaluated the effects of CC on markers of inflammation in cell culture and wound fluid from diabetic patients. Methods Lipopolysaccharide-induced release of tumor necrosis factor-α and interleukin-6 from interferon-γ–activated THP-1 monocytes was measured in the presence or absence of CC or CC collagen digests. In the clinical study, 17 individuals with mildly inflamed diabetic foot ulcers were randomized to receive CC ointment (CCO) or hydrogel. Weekly assessments included wound appearance and measurements. Wound exudate was collected at baseline and at 2 and 4 weeks of treatment. A multiplex assay was used to measure levels of analytes, including those associated with inflammation and with inflammation resolution. Results Lower levels of tumor necrosis factor-α and interleukin-6 were found in media of cells cultured with CC or CC digests of collagen type I or III than for untreated lipopolysaccharide controls (P < .05). Clinically, CCO and hydrogel resulted in improvement in wound appearance and a decrease in mean wound area. The CCO, but not the hydrogel, was found to increase the level of analytes associated with resolution of inflammation while decreasing those associated with inflammation. There was a general correlation between resolution of inflammation and healing. Conclusions These results support a hypothesis that debridement with CCO is associated with decreased inflammation and greater progress toward healing.

Background:Chronic non-bacterial osteomyelitis (CNO) is an immune-mediated disease associated with cytokine dysbalance.Objectives:The aim of our study was to evaluate the cytokines levels in CNO and compare to juvenile idiopathic arthritis (JIA) – disease with immune-mediated mechanism.Methods:The diagnosis of CNO made with criteria, proposed by Jansson (2007, 2009), after the exclusion of other causes of bone disease [1]. We included 42 patients with NBO, 28 patients with non-systemic juvenile idiopathic arthritis (JIA). We evaluated plasma levels of 14-3-3 protein, S100A8/S100A9-protein, interleukine-6 (IL-6), interleukine-18 (IL-18), interleukine-4 (IL-4), interleukine-17 (IL-17), interleukine-1β (IL-1 β) and tumor necrosis factor-α (TNFα) in 2 groups by the ELISA. Statistical analysis was carried out with Statistica 10.0 software. We utilized descriptive statistics (Me; IQR), Mann-Whitney tests.Results:We have found differences in the proinflammatory biomarkers between CNO, JIA. Patients with NBO had lower levels of studied cytokines, exclude14-3-3-protein, S100A8/S100A9 and interleukin-6 compare to JIA patients (table 1).Table 1.Comparison the cytokine levels between CNO, JIA NParameterNBO (n=42)JIA (n=28)pHemoglobin, g/l112 (104; 124)120 (114.5; 126.0)0.02WBC x 109/l7.9 (7.0; 10.5)8.0 (6.7; 10.0)0.86PLT x 109/l347 (259; 408)336.5 (274.0; 390.5)0.98ESR. mm/h25.0 (9.0; 46.0)8.5 (2.5; 13.0)0.013CRP, mg/l6.1 (0.6; 2.4)1.8 (0.4; 11.9)0.02714-3-3, ng/ml21.4 (18.5; 27.1)19.9 (18.0; 27.8)0.77S100A8/S100A9, ng/ml5.9 (5.2; 6.5)5.9 (5.0; 6.2)0.76IL-6, ng/ml126,2 (112.8; 137.5)132.4 (117.4; 142.9)0.16IL-18, ng/ml270.1 (200.1; 316.1)388.3 (373.9; 405.1)0.0000001IL-4, ng/ml15.3 (11.5; 18.2)18.7 (16.2; 20.2)0.003IL-17, ng/ml83.1 (71.1; 97.3)99.2 (87.3; 115.8)0.003IL-1b, ng/ml47.4 (42.0; 51.3)70.8 (65.3; 73.6)0.0000001TNFa, ng/ml19.4 (17.8; 21.3)23.1 (20.2; 25.9)0.0006Conclusion:Patients with CNO had less proinflammatory activity then JIA patients, besides IL-6 and S100A8/S100A9. Further investigations required for finding new more precise biomarkers and finding possible molecular targets for treatment.This work supported by the Russian Foundation for Basic Research (grant № 18-515-57001)References:[1]Jansson AF, et al.
