A comprehensive systematic review. Int J Rheum Dis 2022; 25:973-981. [PMID: 35791039 DOI: 10.1111/1756-185x.14382] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 05/28/2022] [Accepted: 06/20/2022] [Indexed: 11/30/2022]
Abstract
Rheumatoid arthritis (RA) and osteoarthritis (OA) both are chronic diseases affecting joints. Immune response against collagen in both diseases may have a role in the initiation and progression of the disease. There is a hypothesis that suppression of immune response vs collagen could be a therapeutic approach in RA and OA. Exposure of gut immune system to collagen is a way to suppress immune response against collagen in the joints. So, the current systematic review is aimed to evaluate the effects of collagen supplementation in OA and RA patients. In the current systematic review, online electronic databases including PubMed/MEDLINE, Web of Sciences and Scopus were searched and finally 19 articles were included. The enrolled articles evaluated the effects of collagen supplementation on treatment of OA (n = 9) and RA (n = 10). Intact (n = 4) and hydrolyzed (n = 5) collagen were used to treat OA. All of the studies on RA used intact and type II collagen in their intervention. The last trials on collagen supplementation in RA and OA patients were performed in 2011 and 2016, respectively. High adverse effects of collagen supplementation and its low efficiency compared to routine treatments were reported by several included studies. Also, risk of bias assessment showed that most of the studies had poor quality. Therefore, it is not possible to definitely decide on the beneficial or detrimental effects of collagen supplementation on OA and RA patients. Further studies are needed to reach a final decision.

BAFF, involved in B cell activation through the NF-κB pathway, is related to disease activity and bone destruction in rheumatoid arthritis. Acta Pharmacol Sin 2021; 42:1665-1675. [PMID: 33483588 PMCID: PMC8463593 DOI: 10.1038/s41401-020-00582-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Accepted: 11/16/2020] [Indexed: 02/02/2023] Open
Abstract
B cell activating factor of TNF family (BAFF) is a member of TNF ligand superfamily and plays a key role in B cell homeostasis, proliferation, maturation, and survival. In this study, we detected BAFF level, the expressions of BAFF receptors and important molecules in NF-κB pathway in rheumatoid arthritis (RA) patients and analyzed the correlation between BAFF level and clinical variables, laboratory parameters or X-ray scores in order to elucidate the roles of BAFF in RA. A total of 50 RA patients and 50 healthy controls (HCs) were enrolled. We showed that the serum BAFF level in RA patients was significantly higher than that of HCs, and the percentages of B cell subsets (CD19+ B cells, CD19+CD27+ B cells, CD19+CD20+CD27+ B cells, and CD19+CD20-CD27+ B cells) in the serum of RA patients were significantly increased compared with those of HCs. The percentages of CD19+BAFFR+ B cells, CD19+ BCMA+ B cells, and CD19+ TACI+ B cells in RA patients were significantly increased compared with those in HCs. The expression of important molecules in the NF-κB pathway (MKK3, MKK6, p-P38, p-P65, TRAF2, and p52) was significantly higher in RA patients than in HCs, but p100 level in RA patients was lower than that in HCs. The serum BAFF level was positively correlated with C-reactive protein, rheumatoid factor, disease activity score (in 28 joints), swollen joint counts, tender joint counts, and X-ray scores. When normal B cells were treated with BAFF in vitro, the percentages of the B cell subset and the expression of BAFF receptors were significantly upregulated. BAFF also promoted the expression of MKK3, MKK6, p-P38, p-P65, TRAF2, and p52. In conclusion, this study demonstrates that BAFF level is correlated with the disease activity and bone destruction of RA. BAFF is involved in the differentiation, proliferation, and activation of B cells in RA through NF-κB signaling pathway, suggesting that BAFF might be an ideal therapeutic target for RA.

Abstract
OBJECTIVE Methotrexate (MTX) increases the risk of alopecia and stomatitis, but the prevalence of these adverse events among rheumatic patients taking MTX is poorly defined. We conducted a systematic literature review and meta-analysis to estimate the prevalence of alopecia and stomatitis with MTX in rheumatic diseases. METHODS We searched PubMed, The Cochrane Library, and CINAHL databases for double-blind randomized controlled trials (RCTs) with an MTX monotherapy arm. Alopecia, stomatitis, and oral/mouth ulcers data were extracted. The quality of trials was assessed by 2 authors. We included trials published since 1990 that used at least 10 mg of MTX weekly, coadministered with folic or folinic acid. We estimated the prevalence using random-effects models because heterogeneity was anticipated. Two estimates of prevalence were included; the lower bound estimate included all trials (assuming no alopecia and stomatitis if not mentioned), and the upper bound estimate included only those that specifically described prevalence estimates of alopecia or stomatitis. RESULTS Of 3,954 studies identified, 20 RCTs were included, with a total of 24 MTX monotherapy arms, of which 10 reported the prevalence of alopecia (n = 1,113), and 21 reported stomatitis or mouth/oral ulcers (n = 2,056). The prevalence of alopecia was between 1.0% and 4.9%. The prevalence of stomatitis was between 5.7% and 8.0%. CONCLUSION This meta-analysis gives more precise estimates of mucocutaneous adverse events that occur in rheumatic disease patients taking MTX. These estimates will help inform patient decision-making regarding MTX.

Molecular assembly of recombinant chicken type II collagen in the yeast Pichia pastoris. SCIENCE CHINA-LIFE SCIENCES 2018; 61:815-825.

Abstract
Effective treatment of rheumatoid arthritis can be mediated by native chicken type II collagen (nCCII), recombinant peptide containing nCCII tolerogenic epitopes (CTEs), or a therapeutic DNA vaccine encoding the full-length CCOL2A1 cDNA. As recombinant CCII (rCCII) might avoid potential pathogenic virus contamination during nCCII preparation or chromosomal integration and oncogene activation associated with DNA vaccines, here we evaluated the importance of propeptide and telopeptide domains on rCCII triple helix molecular assembly. We constructed pC- and pN-procollagen (without N- or C-propeptides, respectively) as well as CTEs located in the triple helical domain lacking both propeptides and telopeptides, and expressed these in yeast Pichia pastoris host strain GS115 (his4, Mut+) simultaneously with recombinant chicken prolyl-4-hydroxylase α and β subunits. Both pC- and pN-procollagen monomers accumulated inside P. pastoris cells, whereas CTE was assembled into homotrimers with stable conformation and secreted into the supernatants, suggesting that the large molecular weight pC-or pN-procollagens were retained within the endoplasmic reticulum whereas the smaller CTEs proceeded through the secretory pathway. Furthermore, resulting recombinant chicken type II collagen pCα1(II) can induced collagen-induced arthritis (CIA) rat model, which seems to be as effective as the current standard nCCII. Notably, protease digestion assays showed that rCCII could assemble in the absence of C- and N-propeptides or telopeptides. These findings provide new insights into the minimal structural requirements for rCCII expression and folding.

Abstract
OBJECTIVE Methotrexate is an effective treatment for a variety of inflammatory diseases. Robust evidence on the risk of serious liver injury is lacking. The aim of this study was to evaluate the relative risk and severity of liver disease among patients treated with methotrexate. METHODS We searched PubMed and the Cochrane Central Register of Controlled Trials from 1 January 1990 to 24 April 2014 for double-blind randomised controlled trials of methotrexate versus comparator agents in adults with rheumatoid arthritis, psoriasis, psoriatic arthritis or inflammatory bowel disease. Studies with less than 100 subjects or of less than 24 weeks' duration were excluded. Two investigators independently searched both the databases. All authors reviewed the selected studies. We compared relative risk (RR) differences using the Mantel-Haenszel random effects method to assess total liver adverse events, minor liver enzyme abnormalities (≤ 3 ULN), major liver enzyme abnormalities (>3 ULN or treatment withdrawal) and a composite outcome of liver failure, fibrosis, cirrhosis or death. RESULTS A total of 32 studies with 13,177 participants met our inclusion criteria. Methotrexate was associated with an increased risk of total adverse liver events, RR = 2.19 (95% CI: 1.73-2.77, I(2) = 68%), as well as minor and major liver enzyme abnormalities, RR = 2.16 (95% CI: 1.67-2.79, I(2) = 68%) and RR = 2.63 (95% CI: 1.90-3.64, I(2) = 10%), respectively. Patients treated with methotrexate were not at increased risk of liver failure, cirrhosis or death, RR = 0.12 (95% CI: 0.01-1.09, I(2) = 0%). CONCLUSION Our study found an increased risk of elevated transaminases but not liver failure, cirrhosis or death with methotrexate compared to other agents. We were unable to assess long-term liver toxicity due to the short duration of included clinical trials.

Abstract
In patients with rheumatoid arthritis (RA), symptoms of joint stiffness and pain may be most severe in the morning, resulting in impaired ability to carry out normal morning functions. Although morning stiffness was included in the criteria for classification and remission of RA, defined by the American College of Rheumatology (ACR) in 1987, the approach to assessment of this circadian symptom has not been standardized, and other circadian aspects of the disease (i.e. pain, functional ability) were not included. A bibliographic study of papers published in English in the period January 2007 to January 2010 and reporting morning stiffness, pain or function was undertaken to investigate methods of assessing circadian aspects of RA. A total of 73 studies were identified using Medline, including 62 clinical trials. Full papers were obtained for 52 reports of clinical studies (84%), most of which (44/52, 85%) assessed duration of morning stiffness. Only two studies (4%) specified that severity of morning stiffness was assessed, only three (6%) assessed pain in the morning, and none assessed morning functional ability. These findings suggest the need for consistent reporting of a measure to reflect the impaired morning function, arising from joint stiffness and pain that is commonly experienced by patients.

Abstract
Chicken type II collagen (CCII) is a protein extracted from the cartilage of chicken breast and exhibits intriguing possibilities for the treatment of autoimmune diseases by inducing oral tolerance. In this study, we investigated the effects of CCII on inflammatory and immune responses to the mesenteric lymph node lymphocytes (MLNLs) and the mechanisms by which CCII regulates beta2-adrenergic receptor (beta2-AR) signal transduction in collagen-induced arthritis (CIA) rats. The onset of secondary arthritis in rats appeared around day 14 after injection of CCII emulsion. Remarkable secondary inflammatory response and lymphocytes proliferation were observed in CIA rats. The administration of CCII (10, 20, 40μgkg(-1)day(-1), days 15-22) could significantly reduce synovial hyperplasia, lymphatic follicle hyperplasia, inflammatory cells infiltration of MLNLs in CIA rats. CCII (10, 20, 40μgkg(-1)day(-1), days 15-22) restored the previously decreased level of cAMP of MLNLs of CIA rats. Meanwhile, CCII increased total protein expressions of beta2-AR, GRK2 and decreased that of beta-arrestin1, 2 of MLNLs in CIA rats but had an slight effect on GRK3. CCII further increased plasmatic protein expressions of GRK2, G(α)s and decreased that of beta-arrestin1, 2, beta2-AR, and increased membrane protein expressions of beta2-AR, GRK2, G(α)s and decreased that of beta-arrestin1, 2 of MLNLs in CIA rats. These results demonstrate that the mechanisms of CCII on beta2-AR desensitization and beta2-AR-AC-cAMP transmembrane signal transduction of MLNLs play crucial roles in pathogenesis of this disease.

Serological investigation of IgG levels and subclasses in rheumatoid arthritis patients following ingestion of bovine type II collagen: results of a double blind, randomised controlled trial. Clin Rheumatol 2010; 30:193-9.

Abstract
The purpose of this study was to investigate whether clinical improvement in patient with rheumatoid arthritis (RA) taking oral Bovine type II collagen (bCII) is associated with changes in levels of anti-bCII total IgG antibody and its subclasses. Four groups were given either 5, 0.5 or 0.05 mg of bCII or a placebo in a double-blind randomised control trial. The sera IgG anti-collagen type II and antibodies of the IgG subclasses, IgG1-4, were measured at the start and end of the trial by ELISA. Total IgG anti-collagen II antibodies in the pooled active treatment groups were statistically significantly reduced compared with the placebo group (p = 0.021). Decreasing total IgG titres were observed in the 0.5-mg group (p = 0.008), 0.05-mg group (p = 0.004) and 5-mg group (p = 0.078) before and after treatment. For IgG1, IgG2, IgG3 and IgG4 subclasses, in the 0.5-mg group in which the best clinical response was observed, there was statistically significant decreases observed in the IgG2 and IgG3 subclasses (p = 0.047, p = 0.046). Treatment with bCII in patients with RA led to a reduction in anti-collagen II antibody titre indicating an active biological effect as observed previously in animal model of RA. The largest decrease in total and subclasses of anti-collagen antibody titres occurred in the groups of patients with the best therapeutic response to bCII, supporting the conclusion of the clinical trial and suggests that immune regulation explains the therapeutic effect.

Abstract
Introduction Chicken type II collagen (CCII) is a protein extracted from the cartilage of chicken breast and exhibits intriguing possibilities for the treatment of autoimmune diseases by inducing oral tolerance. A 24-week, double-blind, double-dummy, randomized, methotrexate (MTX)-controlled study was conducted to evaluate the efficacy and safety of CCII in the treatment of rheumatoid arthritis (RA). Methods Five hundred three RA patients were included in the study. Patients received either 0.1 mg daily of CCII (n = 326) or 10 mg once a week of MTX (n = 177) for 24 weeks. Each patient was evaluated for pain, morning stiffness, tender joint count, swollen joint count, health assessment questionnaire (HAQ), assessments by investigator and patient, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) by using the standard tools at baseline (week 0) and at weeks 12 and 24. Additionally, rheumatoid factor (RF) was evaluated at weeks 0 and 24. Measurement of a battery of biochemical parameters in serum, hematological parameters, and urine analysis was performed to evaluate the safety of CCII. Results Four hundred fifty-four patients (94.43%) completed the 24-week follow-up. In both groups, there were decreases in pain, morning stiffness, tender joint count, swollen joint count, HAQ, and assessments by investigator and patient, and all differences were statistically significant. In the MTX group, ESR and CRP decreased. RF did not change in either group. At 24 weeks, 41.55% of patients in the CCII group and 57.86% in the MTX group met the American College of Rheumatology 20% improvement criteria (ACR-20) and 16.89% and 30.82%, respectively, met the ACR 50% improvement criteria (ACR-50). Both response rates for ACR-20 and ACR-50 in the CCII group were lower than those of the MTX group, and this difference was statistically significant (P < 0.05). The DAS28 (disease activity score using 28 joint counts) values of the two treatment groups were calculated, and there was a statistically significant difference between the two treatment groups (P < 0.05). Gastrointestinal complaints were common in both groups, but there were fewer and milder side effects in the CCII group than in the MTX group. The incidence of adverse events between the two groups was statistically significant (P < 0.05). Conclusions CCII is effective in the treatment of RA and is safe for human consumption. CCII exerts its beneficial effects by controlling inflammatory responses through inducing oral tolerance in RA patients. Trials Registration Clinical trial registration number: ChiCTR-TRC-00000093.
