Combination of Curcuminoid with Acupressure for Inflammation and Pain in Elderly People with Osteoarthritis Genu: Protocol for a Randomized Controlled Trial.

BACKGROUND: Curcuminoids and acupressure have beneficial effects in reducing pain and inflammation in patients with Osteoarthritis. However, only a few clinical trials are investigating biomarkers to prove this objectively. OBJECTIVE: This study aimed to investigate the efficacy of acupressure and curcuminoids to inflammatory markers and pain in elderly with Osteoarthritis Genu. METHODS: Randomized controlled trial (RCT) was conducted among elderly with Osteoarthritis. All participants were randomized to divided into the group with 30 mg curcuminoids from turmeric extract capsules and acupressure (group 1) or the group with placebo and sham acupressure (group 2) for 3 weeks. RESULTS: The study was approved by the research ethics board and Clinical Trials.gov had reviewed this protocol. The extracts were manufactured from May 2023 to June 2023. Participant recruitment was conducted in September-October 2023, a total of 72 participants aged over 60 years had participated of whom 75.0% (n=54) were female. Data was analyzed in April of 2024, and dissemination of results by the end of 2024. CONCLUSIONS: Primary outcomes were assessed at baseline and after intervention and related to inflammatory markers, endorphin hormones, and cycloxygenase-2 hormone in the blood. Additionally, secondary outcomes included pain, ability to activity daily living, and quality of life. The beneficial effects that may be found in this trial can be exceptionally relevant in clinical practice, justifying this scientific question. The benefits of herbs and acupressure can be helpful to additional options in treating inflammation and pain in patients with Osteoarthritis.

Immunogenicity and safety of inactivated SARS-CoV-2 vaccine in haemodialysis patients: a prospective cohort study.

End-stage renal disease patients on haemodialysis (HD) have been largely excluded from SARS-CoV-2 vaccine trials due to safety reasons and shown to mount lower responses to vaccination. This study aims to evaluate the immunogenicity and safety of inactivated COVID-19 vaccine among HD patients compared to healthy controls. All subjects who received the primary inactivated COVID-19 vaccination had their blood samples tested 21 days after the second dose. We report the immunogenicity based on anti-RBD IgG titre (IU/mL), the inhibition rate of neutralizing antibodies (NAbs) (%) to RBD, and seroconversion rates. Adverse events were assessed within 30 min and on the 7th day after each dose. Among 75 HD patients and 71 healthy controls, we observed no significant difference in all immunogenicity measures: anti-RBD IgG GMT (277.91 ± 7.13 IU/mL vs. 315.50 ± 3.50 IU/mL, p = 0.645), NAbs inhibition rate (82% [53-96] vs. 84% [39-98], p = 0.654), and seroconversion rates (anti-RBD IgG: 86.7% vs. 85.9%, p = 0.895; NAbs: 45.3% vs. 60.6%, p = 0.065). The number of adverse events is not significantly different between the two groups. The primary inactivated SARS-CoV-2 vaccination elicits an adequate antibody response and can be safely administered in haemodialysis patients.

Immunogenicity and safety of COVID-19 BNT162b2 booster vaccine in end-stage kidney disease patients receiving haemodialysis in Yogyakarta, Indonesia: a cohort prospective study.

BACKGROUND: A significant decrease in antibody titres several months after COVID-19 primary vaccination in end-stage kidney disease (ESKD) patients receiving maintenance haemodialysis has recently been reported. The waning in antibody titres has led to the recommendations for a booster dose to increase the antibody titres after vaccination. Consequently, it is crucial to analyse the long-term humoral immune responses after COVID-19 primary vaccination and assess the immunogenicity and safety of booster doses in haemodialysis (HD) patients. METHODS: Patients on maintenance haemodialysis who received the primary vaccine of CoronaVac (Sinovac) vaccine were administered with BNT162b2 (Pfizer-BioNTech) as the booster dose. The immunogenicity was assessed before (V1), one month (V2) and eight months (V3) after the primary vaccination, as well as one month after the booster dose (V4). Patients were followed up one month after the booster dose to assess the adverse events (AEs). RESULTS: The geometric mean titre (GMT) of anti-SARS-CoV-2 S-RBD IgG antibody at 8 months after the primary vaccination increased significantly to 5,296.63 (95%CI: 2,930.89-9,571.94) U/mL (p = < 0.0001) compared to before the primary vaccination. The GMT also increased significantly to 19,142.56 (95% CI: 13,489.63-27,227.01) U/mL (p < 0.0001) 1 month after the booster vaccine. Meanwhile, the median inhibition rate of neutralizing antibodies (NAbs) at 8 months after the primary vaccine and 1 month after the booster dose were not significantly different (p > 0.9999). The most common AEs after the booster dose included mild pain at the injection site (55.26%), mild fatigue (10.53%), and swelling at the injection site (10.53%). No serious AEs were reported. CONCLUSIONS: The majority of ESKD patients on haemodialysis mounted a good antibody response to the BNT162b2 booster vaccination with tolerable adverse events.

Outcomes of vaccinations against respiratory diseases in patients with end-stage renal disease undergoing hemodialysis: A systematic review and meta-analysis.

Due to the nature of the disease, end-stage renal disease (ESRD) patients suffer from dysfunction of the adaptive immune system, which leads to a poorer response to vaccination. Accordingly, it is crucial to evaluate the efficacy and safety of management strategies, including vaccinations, which could potentially reduce the risk of respiratory diseases, such as pneumonia, influenza, or COVID-19, and its associated outcomes. We searched PubMed, CENTRAL, ScienceDirect, Scopus, ProQuest, and Google Scholar databases using designated MeSH keywords. The risk of bias was assessed using ROBINS-I. The quality of evidence was assessed using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. Relative risk (RR) and 95% confidence interval (CI) were calculated. Heterogeneity was investigated using forest plots and I2 statistics. This systematic review included a total of 48 studies, with 13 studies of influenza (H1N1 and H3N2) vaccination and 35 studies of COVID-19 vaccination. H1N1 vaccination in ESRD patients undergoing hemodialysis induced lower seroconversion rates (RR 0.62, 95% CI: 0.56-0.68, p <0.00001) and lower seroprotection rates (RR 0.76, 95% CI: 0.70-0.83, p <0.00001) compared to controls. H3N2 vaccination in ESRD patients undergoing hemodialysis yielded lower seroconversion rates (RR 0.76, 95% CI: 0.68-0.85, p <0.00001) and lower seroprotection rates (RR 0.84, 95% CI: 0.77-0.90, p <0.00001) compared to controls. Twenty-nine studies demonstrate significantly lower antibody levels in ESRD patients undergoing hemodialysis compared to the controls following COVID-19 vaccination. This review presents evidence of lower seroconversion and seroprotection rates after vaccination against viral respiratory diseases in patients with ESRD undergoing hemodialysis. Since hemodialysis patients are more susceptible to infection and severe disease progression, a weakened yet substantial serological response can be considered adequate to recommend vaccination against respiratory diseases in this population. Vaccination dose, schedule, or strategy adjustments should be considered in stable ESRD patients on maintenance hemodialysis.

Influence of Oral Microbiota on the Presence of IgA Anti-Citrullinated Protein Antibodies in Gingival Crevicular Fluid.

Introduction: The relation between rheumatoid arthritis (RA) and periodontitis (PD) has been investigated ever since the discovery of the citrullinating enzyme peptidyl arginine deaminase presents in the oral bacterium Porphyromonas gingivalis. Recently, we demonstrated the presence of RA autoantibodies, especially of IgA anti-citrullinated protein antibody (ACPA), in gingival crevicular fluid (GCF) of Indonesian patients with and without RA or PD which might indicate the local formation of RA antibodies in the periodontium. Aim: The purpose of this study was to assess whether the subgingival microbiome is related to the presence of IgA ACPA in the GCF of healthy individuals with or without PD. Patients and Methods: Healthy individuals with a known periodontal status and high IgA ACPA (>0.1 U/ml) in GCF (n = 27) were selected and matched for age, gender, periodontal status, and smoking status with 27 healthy individuals without IgA ACPA in their GCF. Taxonomic profiling of the subgingival microbiome was based on bacterial 16S rRNA gene sequencing. Downstream analyses were performed to assess compositional differences between healthy subjects with or without IgA ACPA in GCF and with or without PD. Results: Between groups with or without PD, or with or without IgA ACPA in GCF, no differences in alpha diversity were seen. Beta diversity was different between groups with or without PD (p < 0.0001), and a trend was seen in subjects with PD between subjects with or without IgA ACPA in GCF (p = 0.084). Linear discriminant analysis effect size (LEfSe) revealed no significant differences in the total population between subjects with IgA ACPA compared to subjects without IgA ACPA in GCF. Although Porphyromonas was not identified by LEfSe, its relative abundance was significantly higher in healthy individuals with high IgA ACPA in GCF compared to individuals without IgA ACPA in GCF (p = 0.0363). Zooming in on the subgroup with PD, LEfSe revealed that species Neisseriaceae, Tannerella, and Haemophilus were more abundant in the subjects with IgA ACPA in GCF compared to subjects without IgA ACPA in GCF. Conclusion: Periodontitis and certain taxa, including Porphyromonas, seem to be associated with the local presence of ACPA in the periodontium.

No Obvious Role for Suspicious Oral Pathogens in Arthritis Development.

A particular role for Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa) has been suggested in periodontitis and rheumatoid arthritis (RA), as these bacteria could initiate the formation of rheumatoid factor (RF) and anticitrullinated protein autoantibodies (ACPA). We assessed whether serum antibodies against Pg and Aa in RA patients and non-RA controls reflect the subgingival presence of Pg and Aa, and evaluated the relationship of these antibodies to the severity of periodontal inflammation and RA-specific serum autoantibodies. In 70 Indonesian RA patients and 70 non-RA controls, the subgingival presence of Pg and Aa was assessed by bacterial 16S rRNA gene sequencing, and serum IgG levels specific for Pg and Aa were determined. In parallel, serum levels of ACPA (ACPA:IgG,IgA) and RF (RF:IgM,IgA) were measured. The extent of periodontal inflammation was assessed by the periodontal inflamed surface area. In both RA patients and the controls, the presence of subgingival Pg and Aa was comparable, anti-Pg and anti-Aa antibody levels were associated with the subgingival presence of Pg and Aa, and anti-Pg did not correlate with ACPA or RF levels. The subgingival Pg and Aa were not related to RA. No noteworthy correlation was detected between the antibodies against Pg and Aa, and RA-specific autoantibodies.

Increased IgA anti-citrullinated protein antibodies in the periodontal inflammatory exudate of healthy individuals compared to rheumatoid arthritis patients.

AIM: To assess rheumatoid arthritis (RA)-associated autoantibodies in the gingivocrevicular fluid (GCF) of RA patients and healthy controls with or without periodontal disease, as chronic mucosal inflammation in periodontal disease is hypothesized to contribute to the formation of these autoantibodies. MATERIALS AND METHODS: Anti-citrullinated protein antibodies (ACPA), rheumatoid factor (RF), and their IgA isotypes were assessed in the serum and GCF of RA patients (n = 72) and healthy controls (HC, n = 151). The presence and levels of these antibodies were studied in relation to interleukin (IL)-8 and periodontal disease. RESULTS: In contrast to the HC, the levels of ACPA and RF in the serum and GCF of the RA patients were strongly correlated (p < .0001). The HC with high levels of IgA-ACPA (n = 27) also had significantly higher levels of total IgG, total IgA, and IL-8 in the GCF than the HC with low levels of IgA-ACPA in the GCF (n = 124). Periodontal inflammation and smoking were seen more frequently in the group with high levels of IgA-ACPA compared to the group with low IgA-ACPA. CONCLUSION: The IgA-ACPA in the GCF of HC may be associated with periodontal inflammation and smoking, and could be involved in the progression to RA.

Cytokines in gingivocrevicular fluid of rheumatoid arthritis patients: A review of the literature.

OBJECTIVE: Rheumatoid arthritis (RA) and periodontitis share several pathological features including bone and soft tissue destruction and high levels of circulating inflammatory proteins. Studies related to cytokines in the periodontal inflammatory exudate (gingivocrevicular fluid, GCF) of RA patients might provide insight into the association between periodontitis and RA. The aim of our study was to review the literature on cytokines in GCF of RA patients including the effect of anti-rheumatic treatment with biological disease-modifying anti-rheumatic drugs (DMARDs) and periodontal treatment on these cytokines. MATERIALS AND METHODS: MedLine/PubMed searches with different combinations of keywords "rheumatoid arthritis or RA" and "crevicular fluid or GCF" until June 2019 revealed 64 articles. Ten cross-sectional observational studies and nine treatment studies fulfilled the inclusion criteria. RESULTS: Rheumatoid arthritis patients have increased circulating and GCF levels of pro-inflammatory cytokines and proteins, despite anti-rheumatic treatment with biological DMARDs. Presence of periodontitis was accompanied by higher cytokine and protein levels. Treatment of periodontitis resulted in a decrease of these levels. CONCLUSION: Analysis of GCF of RA patients reveals that the relationship between periodontitis and RA is bidirectional, probably caused by a non-specific inflammatory burden. Data for a specific relationship are barely present in GCF.

A Double-blind, Randomized Controlled Trial of Ciplukan (Physalis angulata Linn) Extract on Skin Fibrosis, Inflammatory, Immunology, and Fibrosis Biomarkers in Scleroderma Patients.

BACKGROUND: scleroderma is an autoimmune disease characterized by organ fibrosis, resistant to standard treatment. It is suspected the addition of Physalis angulata Linn. (Ciplukan) extract as adjuvant therapy can improve the scleroderma skin fibrosis. The aim at this study is to evaluate the effect of ciplukan extract as adjuvant on scleroderma skin fibrosis in standard therapy, based on modified Rodnan skin scale (MRSS), inflammatory biomarkers, immunology and serum fibrosis. METHODS: double-blind, randomized clinical trial was performed in scleroderma patients with stable disease at Cipto Mangunkusumo hospital and Hasan Sadikin hospital during November 2015-March 2017 who met the selection criteria and continued to receive standard therapy. The subjects were randomly allocated into two groups: the study group received the ciplukan  extract 3 x 250 mg / day for 12 weeks and the placebo group. Examination of MRSS, ESR, P1NP, BAFF and sCD40L was performed every 4 weeks until the end of the study. RESULTS: fifty-nine subjects completed the study. They consisted of 29 subjects of the treatment group and 30 of the placebo group, with an average age of 41 (SD 9) years, the proportion of women: male = 9 : 1. There was a significant improvement of skin fibrosis in the study group with a highly significant decrease in MRSS (35.9% VS 6.3%, p <0.001) and a relative decrease in P1NP levels (17.8% VS 0.7%, p = 0.002). No decrease in ESR, BAFF and sCD40L levels in both groups. There was a weak but significant positive correlation between MRSS with P1NP levels (r = 0.236, p = 0.036). CONCLUSION: Ciplukan extract with dose 3 x 250 mg for 12 weeks as adjuvant on scleroderma standard therapy alleviates skin fibrosis significantly based on MRSS and P1NP levels.

Prevalence and severity of periodontitis in Indonesian patients with rheumatoid arthritis.

BACKGROUND: Patients with rheumatoid arthritis (RA) may have more prevalent and severe periodontitis than healthy controls. Periodontitis may increase the systemic inflammation in RA. The aim of this study is to assess periodontitis prevalence and severity and its potential association with systemic inflammation in Indonesian patients with RA. METHODS: A full-mouth periodontal examination including probing depth, gingival recession, plaque index, and bleeding on probing was performed in 75 Indonesians with RA and 75 age-, sex-, and smoking-matched Indonesian controls. A validated questionnaire was used to assess smoking, body mass index, education, and medical conditions. In addition, in all participants, the use of drugs was noted, and erythrocyte sedimentation rates and serum levels of high-sensitivity C-reactive protein (hsCRP), rheumatoid factor, and anti-citrullinated protein antibodies were measured. Differences in periodontitis prevalence and 12 measures of periodontitis severity between patients with RA and controls were analyzed using univariate analyses. RESULTS: No significant differences in periodontitis prevalence and 11 measures of periodontitis severity between patients with RA and controls were observed. Conversely, patients with RA had a significantly lower surface area of healthy pocket epithelium versus controls (P = 0.008), and a tendency toward higher hsCRP levels was observed in patients with RA with severe periodontitis compared with patients with RA with no mild or moderate periodontitis (P = 0.063). It has to be noted that all patients with RA were on anti-inflammatory drugs, whereas none of the controls used such drugs. CONCLUSION: Prevalence and severity of periodontitis in Indonesian patients with RA is comparable to controls but with less healthy pocket epithelium than in controls and a tendency toward a higher inflammatory state in patients with RA and severe periodontitis.

Ability of curcuminoid compared to diclofenac sodium in reducing the secretion of cycloxygenase-2 enzyme by synovial fluid's monocytes of patients with osteoarthritis.

AIM: to assess the ability of curcuminoid from Curcuma domestica Val in reducing the cycloxygenase-2 secretion by synovial fluid's monocytes compared to diclofenac sodium in patients with osteoarthritis. METHODS: this was a prospective randomized open end blinded evaluation (PROBE) study. The subjects were patients with knee osteoarthritis who were divided randomly into two groups, the first group received 30 mg 3 times daily of curcuminoid and the second group received 25 mg 3 times daily of diclofenac sodium. The joints aspiration was done and the secretion of cycloxygenase-2 enzyme by synovial fluid's monocytes was evaluated by scoring method before and after 4 weeks of treatments. RESULTS: a total of 80 patients with knee osteoarthritis were enrolled. In curcuminoid group the average scores were 1.84±0.37 and 1.15±0.28 respectively (p<0.001). In diclofenac group the average scores were 1.79±0.38 and 1.12±0.27 respectively (p<0.001). In curcuminoid group the decreasing score of cycloxygenase-2 secretion was 0.70±0.51 while in diclofenac group was 0.67±0.45. There was no significant difference in decreasing the score of cycloxygenase enzyme secretion between both treatment groups (p=0.89). CONCLUSION: the ability of curcuminoid from Curcuma domestica Val. rhizome extract was not significantly different compared to diclofenac sodium in suppressing the secretion of cycloxygenase-2 enzyme by synovial fluid's monocytes.
