Linking genetic susceptibility to Crohn's disease with Th17 cell function: IL-22 serum levels are increased in Crohn's disease and correlate with disease activity and IL23R genotype status

BACKGROUND: We analyzed the influence of Crohn's disease (CD)-associated IL23R gene variants on IL-22 that is expressed in IL-23R+ Th17 cells. METHODS: IL-22 serum levels were measured in 242 CD patients and in 31 healthy controls. Subanalyses included serum levels of IL-6, TNF-alpha, IL-17A, IL-17F, C-reactive protein (CRP), and leukocyte count. In all patients, genotyping for 10 CD-associated IL23R single nucleotide polymorphisms (SNPs) and the 3 main CD-associated CARD15 variants was performed. RESULTS: There was a highly significant increase in IL-22 serum expression in CD patients compared to healthy controls (P = 2.53 x 10(-9)). IL-22 serum levels correlated with disease activity: IL-22 levels in patients with a Crohn's disease activity index (CDAI) >150 were significantly higher than in patients with a CDAI <150 (P = 0.001), while TNF-alpha and IL-6 were not significantly different between these 2 groups. Analyzing the effect of 10 IL23R variants on IL-22 serum levels, we demonstrated that the quotients of mean IL-22 serum levels of carriers of the minor allele to the mean serum IL-22 in wildtype carriers correlated highly with the corresponding CD susceptibility risk for each gene variant (r = 0.807). The IL-22 levels in carriers of CD risk-increasing IL23R variants were significantly higher than in carriers of CD risk-decreasing IL23R variants (P = 0.008). CONCLUSIONS: The Th17 cytokine IL-22 is expressed at high levels in CD and correlates with disease activity, offering a better separation between active and inactive CD than IL-6 and TNF-alpha. IL23R genotypes influence IL-22 serum expression, linking genetic CD susceptibility to Th17 cell function for the first time.

Increased serum interleukin 23 in patients with systemic sclerosis

OBJECTIVE: The relationship between systemic sclerosis (SSc) and interleukin 23 (IL-23), a cytokine associated with the differentiation of T lymphocytes, is unknown. We investigated serum IL-23 levels and their clinical association in patients with SSc. METHODS: Serum IL-23 levels were examined by ELISA in 63 patients with SSc, 15 patients with systemic lupus erythematosus (SLE), and 31 healthy individuals. SSc patients comprised 25 with limited cutaneous SSc and 38 with diffuse cutaneous SSc. RESULTS: Serum IL-23 levels were significantly elevated in SSc patients compared to patients with SLE (p < 0.05) and controls (p < 0.005). Elevated serum IL-23 levels were associated with the disease duration (p < 0.05) and the prevalence of pulmonary fibrosis (p < 0.05), although they were not associated with other clinical features, including the extent of skin sclerosis or the severity of pulmonary fibrosis. CONCLUSION: The results suggest that IL-23 is associated with induction of SSc and that blockade of IL-23 can be a potential therapeutic strategy in early SSc.     

Increased serum IL-17 and IL-23 in the patient with ankylosing spondylitis

Interleukin 17 (IL-17) is a Th17 cytokine associated with inflammation, autoimmunity, and defense against some bacteria; it has been implicated in many chronic autoimmune diseases including psoriasis, multiple sclerosis, and systemic sclerosis. However, whether IL-17 plays a role in the pathogenesis of ankylosing spondylitis (AS) remains unclear. To analyze the content of IL-17 and IL-23 in the serum from patients with AS compared with health control subject, 50 patients with AS and 43 healthy volunteers were recruited. Serum IL-17 levels were examined by enzyme linked immunosorbent assay (ELISA). Statistic analyses were performed by SPSS 13.0. Results show that the serum IL-17 and IL-23 levels were significantly elevated in AS patients as compared with normal controls. Nevertheless, no associations of serum IL-17 and IL-23 levels with clinical and laboratory parameters were found; no significant difference regarding serum IL-17 and IL-23 levels was found between less active AS and more active AS. However, there was a strong positive association between the serum levels of IL-17 and IL-23 in the AS patients. Our results indicate increased serum IL-17 and IL-23 levels in AS patients, suggesting that this two cytokine may play critical roles in the pathogenesis of AS. Therefore, further studies are required to confirm this preliminary data.     

Elevated circulating levels of IL-21 and IL-22 define a cytokine signature profile in type 2 autoimmune hepatitis patients

Background and aims. Autoimmune hepatitis (AIH) is a chronic inflammatory condition of the liver in which the immunological mechanisms involved in tissue destruction and/or repair are still unclear. Different pro-inflammatory cytokines have been shown to play a determinant role in AIH pathogenesis. Here, we aim to compare the circulating levels of pro-and anti-inflammatory cytokines such as IL-6, TNF-α, IL-17A/F, IL-21, IL-22, IL-23, and IL-10 in patients with type 2 AIH compared to patients with type 1 AIH and healthy controls (HC). Fourty-six Mexican patients with AIH were recruited in our study. Patients were classified as type 1 or 2 AIH based on immune serological markers. Fourty-four serum samples from healthy individuals were included as controls. Serum cytokine levels were determined by ELISA technique.Results. Compared to healthy controls, serum levels of IL-17F, IL-21, IL-23, IL-10, IL-6, and TNF-α, but not IL-17A and IL-22, were significantly increased in AIH patients. When patients were grouped by aminotransferase activity, a biomarker of active disease, a positive correlation between serum IL-17F and alanine transaminase (rs: 0.4739; P = 0.0009) and aspartate transaminase (rs: 0.4984; P = 0.0004) levels was found. A cytokine signature profile associated with type 2 AIH was characterized by high serum IL-21 (type 1 AIH: 0.66 pg/mL; type 2 AIH: 331.1 pg/mL; P = 0.0042) and IL-22 (type 1 AIH: 0.1 pg/mL; type 2 AIH: 55.26 pg/mL; P = 0.0028) levels.Conclusions. We show for the first time, differential regulation of certain pro-inflammatory cytokines associated with disease progression and AIH type in Mexican patients.

The role of interleukins 4, 17 and interferon gamma as biomarkers in patients with Systemic Lupus Erythematosus and their correlation with disease activity

Aim of the workThis work was designed to study the production of proinflammatory cytokines in SLE patients and their correlation with disease activity and study if they can be used as biomarkers for renal activity in lupus nephritis patients.Patients and methodsThis study was carried out on 70 subjects divided into two groups: Group I (SLE group) which included 40 SLE patients and Group II (Control group) which included 30 apparently healthy controls. The patients were subjected to full history taking and complete clinical examination. Assessment of disease activity in SLE patients by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Sera of patients and controls were screened for the level of cytokine expression of T helper cells including interleukin 17 (IL-17), interleukin 4 (IL-4) and interferon gamma (IFN-γ).ResultsSerum levels of IL-4 were significantly lower while both IL-17 and IFN-γ were significantly higher in SLE patients than in the control group. The most powerful predictor and correlated cytokine with the SLEDAI in SLE patients was IL-17. Higher serum level of IFN-γ was associated with more pyuria and hematuria, while higher IL-17 was associated with more pyuria and proteinuria in SLE patients.ConclusionThe serum level of IL-17 and IFN-γ was proven to be significantly higher in SLE patients and can be used as biomarkers of renal activity.
