The contribution of anti-inflammatory cytokines to rheumatoid arthritis (RA) is not fully comprehended. In the current research we assessed the serum concentration of interleukin (IL)-37 anti-inflammatory cytokine in RA, studied its association to disease activity score 28 (DAS28) and investigated single nucleotide polymorphism (rs2723176) of IL-37 gene as a threat for RA development. The case-control study included 60 RA patients and 30 normal control individuals. Serum IL-37 was assessed by ELISA and genotyped by "sequence-specific primer-polymerase chain reaction (SSP-PCR)". The mean IL-37 was elevated in RA patients (69.42 ng /l ± 62.99) compared to control individuals (14.66 ng /l ± 23.58, p < 0.001). IL-37 tended to increase with age where highest levels were noted in patients more than 60 years (p = 0.037). No Gender influence was found on IL-37 level (p>0.05). At best cut-off value of 31.5 ng/ l, IL-37 had a sensitivity of 73.3% and specificity of 83.3%. No correlation of IL-37 with DAS 28 score was observed (r=0.1497, p=0.2535). For IL-37 (rs2723176) gene polymorphism, C/C genotype was prevailing in both RA (90%) and normal controls (93.3%) compared to A/C or A/A. Also, no variation was found between patents and controls in regard to C/C genotype (OR = 0.643, 95% CI (0.122-3.39, p=0.603). The mean IL-37 concentration in RA patients with C/C genotype (59.70± 67.92) was not different from AC genotype (80.54± 94.18, p=0.4748). We concluded that serum IL-37 had the implication as a diagnostic marker in RA. However, it did not correlate with clinical severity of the disease. Meanwhile, IL-37 (rs2723176) gene polymorphism did not seem to be as a risk factor for RA, nor contributed to the increase of IL-37 level among patients.

Human papillomavirus (HPV) is the most prevalent sexually transmitted infection globally, with significant implications for various anogenital cancers, such as vulval, vaginal, anal, penile, head and neck cancers. HPV infections have been linked to the induction of inflammation. In contrast, Interleukin-37 (IL-37) is recognized as an anti-inflammatory cytokine.

Background: Human interleukin (IL)-37 is a constituent of the IL-1 family with potent anti-inflammatory and immunosuppressive attributes. It has been demonstrated extensive beneficial effects on various diseases; however, its role in the pathogenesis of diabetic cardiomyopathy (DCM) remains unclear.
Methods: , DCM mouse model was established with streptozotocin injection and a high-fat diet in WT and cardiac fibroblasts (CFs) specific hIL-37b overexpression mice (IL-37-Tg).

Aims/introduction: Diabetic foot ulcer (DFU) is a prevalent complication of diabetes characterized by heightened inflammation and impaired wound-healing processes. Interleukin-37 (IL-37) is a natural suppressor of innate inflammation. Here, we aim to investigate the potential of IL-37 in enhancing the healing process of diabetic wounds.

Background: Acute respiratory distress syndrome (ARDS) is prominently characterized by uncontrolled inflammation and high mortality. The effect of interleukin-37 (IL-37) on the prognosis of ARDS remains unclear.
Methods: This prospective cohort study detected and analyzed serum IL-37 levels on day 1 (baseline) in 128 patients with ARDS and 40 healthy controls, and on day 7 in patients with ARDS.
