Background: Overproduction of interleukin (IL)-6 may play a pathologic role in rheumatoid arthritis (RA) and chronic periodontitis (CP). The present study assesses IL-6 receptor (IL-6R) inhibition therapy on the periodontal condition of patients with RA and CP.
Methods: The study participants were 28 patients with RA and CP during treatment with IL-6R inhibitor, and 27 patients with RA and CP during treatment without IL-6R inhibitor. Periodontal and rheumatologic parameters and serum levels of cytokine and inflammatory markers and immunoglobulin G against periodontopathic bacteria were examined after medication with IL-6R inhibitor for 20.3 months on average (T1) and again 8 weeks later (T2).
Results: No differences were observed between the groups in any parameter values at T1, except for serum IL-6 levels. The anti-IL-6R group showed a significantly greater decrease in gingival index, bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and serum levels of IL-6 and matrix metalloproteinase (MMP)-3 from T1 to T2 than the control group (P <0.05). A significant correlation was found between changes in serum anticyclic citrullinated peptide levels and those in PD and CAL in the anti-IL-6R group (P <0.05), whereas both groups exhibited a significant association between changes in serum MMP-3 levels and those in BOP (P <0.05).
Conclusion: Changes in periodontal and serum parameter values were different between the patients with RA and CP during treatment with and without IL-6R inhibitor.

Breast cancer stem cells (CSCs) are resistant to most cancer therapeutics and contribute to tumor recurrence and metastasis. Two breast CSC-promoting transcription factors, truncated glioma-associated oncogene homolog 1 (tGLI1) and signal transducer and activator of transcription 3 (STAT3), have been reported to be frequently co-expressed in HER2-enriched breast cancer and triple-negative breast cancer (TNBC), undergo protein-protein interactions for gene regulation and activation, and functionally cooperate to promote breast CSCs. STAT3 can be activated by activated interleukin-6 receptor/glycoprotein-130 (IL-6R/GP130).

IL-6R inhibitors are widely used in many inflammation-related diseases, especially so during the COVID-19 pandemic. However, their relationship with gastrointestinal perforations (GIPs) has been reported more and more. We comprehensively analyzed IL-6R inhibitors in association with GIPs from the United States FDA Adverse Event Reporting System (FAERS).

Interleukin-6 (IL-6) is a relevant cytokine in rheumatoid arthritis (RA) pathogenesis, potentially activating Janus kinases (JAK)-1, -2, and tyrosine kinase 2 (TYK2), and thus, three signal transducer and activator of transcription (STAT)-1, -3 or - 5 pathways. This pilot study aims to explore differences in phosphorylated (p)STAT3 levels among patients with RA, those not classified as RA (nRA), and healthy donors (HD), providing some clues on the relative contribution of each JAK protein to the downstream of the IL-6-induced STAT3 pathway. Clinical data and blood samples from 80 subjects (41 RA, 14 nRA, and 25 HD) were collected.

Although interleukin (IL)-6 is considered immunosuppressive and tumor-promoting, emerging evidence suggests that it may support antitumor immunity. While combining immune checkpoint inhibitors (ICIs) and radiotherapy in patients with pancreatic cancer (PC) has yielded promising clinical results, the addition of an anti-IL-6 receptor (IL-6R) antibody has failed to elicit clinical benefits. Notably, a robust TGFβ-specific immune response at baseline in PC patients treated solely with ICIs and radiotherapy correlated with improved survival.
