METHODS: Patients (age >18 years) who met the criteria for systemic lupus erythematosus were recruited from 13 centres in Australia, Indonesia, Japan, Malaysia, the Philippines, Singapore, Taiwan, and Thailand, and followed longitudinally. Disease activity (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K] and Physician Global Assessment [PGA] scores) and treatment details were recorded at each visit (at least once every 6 months), and organ damage measured annually according to the Systemic Lupus International Collaborating Clinics Damage Index (SDI). Glucocorticoid use during the study period was recorded as any exposure to prednisolone, cumulative prednisolone exposure, and time-adjusted mean daily prednisolone dose. Multivariate survival analyses were used to examine time-dependent associations of glucocorticoid use with damage accrual (defined as an increase of ≥1 on SDI). A SLEDAI-2K score of 0 was taken to indicate the absence of clinical and serological disease activity; a subset of patients without disease activity during the study were defined by a time-adjusted mean SLEDAI-2K (AMS) score of 0.
FINDINGS: Between May 1, 2013, and Dec 31, 2016, 1707 patients were recruited. Over a median observation period of 2·2 years (IQR 1·5-3·0), damage accrual events were observed in 255 (14·9%) patients. 1405 (82·3%) of patients were exposed to prednisolone, with a median time-adjusted mean prednisolone dose of 5·0 mg/day (IQR 1·9-8·8). As SLEDAI-2K and PGA scores were highly correlated, two multivariable models were set, each including one of these two variables. In the model including AMS score, baseline SDI damage (SDI >0) was independently associated with damage accrual (HR 1·32 [95% CI 1·01-1·73], p=0·0427). In the other model, time-adjusted mean PGA score was independently associated with damage accrual (1·05 [1·02-1·08], p=0·0012). In both models, factors independently associated with damage accrual included time-adjusted mean prednisolone dose, age at enrolment, and ethnicity (Asian vs non-Asians). 157 (9·2%) patients had an AMS score of 0 (no disease activity), among whom 103 (65·6%) had glucocorticoid exposure and the median time-adjusted mean prednisolone dose was 2·0 mg/day (IQR 0·0-5·0). Accrual of irreversible organ damage occurred in 21 (13·4%) of these patients and was independently associated with time-adjusted mean prednisolone dose (HR 1·14 [95% CI 1·03-1·26], p=0·0117), time-adjusted mean PGA score (1·13 [1·03-1·23], p=0·0144), and age at enrolment (1·04 [1·01-1·07], p=0·0061), but not baseline SDI damage (0·94 [0·43-2·06], p=0·8675).
INTERPRETATION: Glucocorticoid use contributes to damage accrual in systemic lupus erythematosus independently of the presence of clinical or serological disease activity.

RESULTS: Minimal inhibitory concentration was determined at 0.625% of the concentration of ACV against S. mutans and E. faecalis and 1.25% of the concentration of ACV against L. casei with two-fold serial dilutions. A concentration of 5 × 10-1% with 10-fold serial dilutions was found to be the MIC value for all three bacteria. No significant differences were found when compared with the positive control (NaOCl) (p = 0.182, p = 0.171, and p = 0.234), respectively, for two-fold serial dilutions and (p = 1.000, p = 0.658, and p = 0.110), respectively for 10-fold serial dilutions. MBC was observed to be 5% ACV for both E. faecalis and S. mutans. However, positive microbial growth was observed on the agar plate when cultured with L. casei. An independent sample t-test showed no significant differences (p > 0.05) in the antimicrobial activities between 5% ACV and 5% pure AA. TEM revealed cell wall and cytoplasmic membrane disruptions on all three bacteria at MIC value.
CONCLUSION: Apple cider vinegar has antimicrobial activities against Enterococcus faecalis, Streptococcus mutans, and Lactobacillus casei at their respective MIC values.
CLINICAL SIGNIFICANCE: Apple cider vinegar can be an alternative antimicrobial dental pulp disinfectant to sodium hypochlorite. Apple cider vinegar can be used safely, especially in children's dental pulp therapy and deep caries management, when adequate tooth isolation is not readily achievable. Thus, adverse reactions commonly associated with other frequently used chemical disinfectants can be avoided.
METHOD: Subjects were allocated into RA (n = 49) or non-RA (NRA) (n = 55) groups, where 3 subgroups were further established; chronic periodontitis (CP), gingivitis (G) and periodontal health (H). Demographic and periodontal parameters were collected. Rheumatology data were obtained from hospital records. Serum and salivary LL-37 levels were measured using enzyme-linked immunosorbent assay and compared for all groups.
RESULTS: For salivary LL-37, RA-CP was significantly higher than NRA-G and NRA-H (P = .047). For serum LL-37, all RA and NRA-CP were significantly higher than NRA-G and NRA-H (P = .024). Salivary LL-37 correlated negatively with clinical attachment loss (CAL) (P = .048), but positively with erythrocyte sedimentation rate (ESR) in RA-H (P = .045). Serum LL-37 showed positive correlation with ESR (P = .037) in RA-G, with C-reactive protein (P = .017) in RA-H, but negative correlation with number of teeth (P = .002) in NRA-CP. Rheumatology data correlated positively with periodontal parameters in RA-CP group.
CONCLUSION: NRA-CP subjects with high serum LL-37 should receive comprehensive periodontal therapy. Positive correlation between rheumatology data and periodontal parameters showed that RA disease stability may be obtained by assessing the periodontal condition. Periodontal therapy is necessary to compliment RA treatment to achieve optimum outcome for RA patients with concurrent CP.
METHODS: This multinational cohort study was conducted at 25 sites across 13 Asia-Pacific countries. We included adult patients aged 18 years or older with stable SLE who were receiving routine clinical care, had two or more visits and had attained stable disease at one or more visits. We categorised stable disease into: LLDAS (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K] score ≤4, Physician Global Assessment [PGA] ≤1, and prednisolone ≤7·5 mg/day); Definitions of Remission in SLE (DORIS) remission (clinical SLEDAI-2K score 0, PGA <0·5, and prednisolone ≤5 mg/day); or complete remission on therapy (SLEDAI-2K score 0, PGA <0·5, and prednisolone ≤5 mg/day). Stable disease categories were mutually exclusive. Tapering was defined as any decrease in dose of corticosteroids or immunosuppressive therapy (mycophenolate mofetil, calcineurin inhibitors, azathioprine, leflunomide, or methotrexate). Using multivariable generalised estimating equations, we compared flares (SELENA-SLEDAI Flare Index) at the subsequent visit after drug tapering. We used generalised estimating equations and Cox proportional hazard models to compare tapering attempts that had begun in LLDAS, remission, and complete remission.
FINDINGS: Between May 1, 2013, and Dec 31, 2020, 4106 patients were recruited to the cohort, 3002 (73·1%) of whom were included in our analysis. 2769 (92·2%) participants were female, 233 (7·8%) were male, and 2636 (88·1%) of 2993 with ethnicity data available were Asian. The median age was 39·5 years (IQR 29·0-50·0). There were 14 808 patient visits for patients in LLDAS, or remission or complete remission, of which 13 140 (88·7%) entered the final multivariable model after excluding missing data. Among the 9863 visits at which patients continued the same therapy, 1121 (11·4%) flared at the next visit, of which 221 (19·7%) were severe flares. Of the 3277 visits at which a patient received a tapering of therapy, 557 (17·0%) flared at the next visit, of which 120 (21·5%) were severe flares. Tapering was associated with higher odds of flare compared with continuing the same therapy (odds ratio [OR] 1·24 [95% CI 1·10-1·39]; p=0·0005). Of 2095 continuous tapering attempts, 860 (41·1%) were initiated in LLDAS, 596 (28·4%) in remission, and 639 (30·5%) in complete remission. Tapering initiated in LLDAS (OR 1·37 [95% CI 1·03-1·81]; p=0·029) or remission (1·45 [1·08-1·94]; p=0·013) had higher odds of flare in 1 year compared with complete remission. Tapering in LLDAS (hazard ratio 1·24 [95% CI 1·04-1·48]; p=0·016) or remission (1·30 [1·08-1·56]; p=0·0054) had a significantly shorter time to first flare than tapering initiated in complete remission. Attaining sustained LLDAS, remission, or complete remission for at least 6 months just before the time of taper was associated with lower odds of flare at next visit, flares in 1 year, and longer time to flare.
INTERPRETATION: Tapering of corticosteroids or immunosuppressive therapy in patients with stable SLE was associated with excess flares. Our findings suggest that drug tapering should be carefully considered, weighing the risks and benefits, and is best exercised in complete (clinical and serological) remission and after maintaining stable disease for at least 6 months.

METHODS: We used data from a large multicenter, longitudinal SLE cohort in which patients received standard of care. The first visit with active disease (defined as SLE Disease Activity Index 2000 [SLEDAI-2K] score ≥6) was designated as baseline, and mSRI attainment (defined as a reduction in SLEDAI-2K ≥4 points with no worsening in physician global assessment ≥0.3 points) was determined at annual intervals from baseline up to 5 years. Associations between mSRI attainment and outcomes including disease activity, glucocorticoid dose, flare, damage accrual, Lupus Low Disease Activity State (LLDAS), and remission were studied.
RESULTS: We included 2,060 patients, with a median baseline SLEDAI-2K score of 8. An mSRI response was attained by 56% of patients at 1 year, with similar responder rates seen at subsequent annual time points. Compared to nonresponders, mSRI responders had significantly lower disease activity and prednisolone dose and higher proportions of LLDAS and remission attainment at each year, and less damage accrual at years 2 and 3. Furthermore, mSRI responder status at 1 year predicted clinical benefit at subsequent years across most outcomes, including damage accrual (odds ratio [OR] range 0.58-0.69, P
METHODS: We included patients from a multicentre longitudinal cohort (recruited between May 1, 2013, and Dec 31, 2019) with active SLE (SLEDAI-2K ≥6) coinciding with an abnormality in at least one of 13 routine laboratory tests, at a visit designated as baseline. At 12 months, we analysed associations between thresholds of improvement in individual laboratory test results, measured as continuous variables, and five clinical outcomes using logistic regression. Primary outcomes were damage accrual and lupus low disease activity state (LLDAS), and secondary outcomes were modified SLE responder index (mSRI), physician global assessment (PGA) improvement of at least 0·3, and flare.
FINDINGS: We included 1525 patients (1415 [93%] women and 110 [7%] men, 1328 [87%] Asian ethnicity) in separate subsets for each laboratory test. The strongest associations with LLDAS and damage protection were seen with improvements in proteinuria (complete response: adjusted odds ratio [OR] 62·48, 95% CI 18·79-208·31 for LLDAS, OR 0·22, 95% CI 0·10-0·49 for damage accrual), albumin (complete response: adjusted OR 6·46, 95% CI 2·20-18·98 for LLDAS, OR 0·42, 95% CI 0·20-1·22 for damage accrual), haemoglobin (complete response: adjusted OR 1·97, 95% CI 1·09-3·53 for LLDAS, OR 0·33, 95% CI 0·15-0·71 for damage accrual), erythrocyte sedimentation rate (complete response: adjusted OR 1·71, 95% CI 1·10-2·67 for LLDAS, OR 0·53, 95% CI 0·30-0·94 for damage accrual), and platelets (complete response: adjusted OR 4·82, 95% CI 1·54-15·07 for LLDAS, OR 0·49, 95% CI 0·20-1·19 for damage accrual). Improvement in serological tests were mainly associated with PGA and mSRI. White cell and lymphocyte count improvements were least predictive.
INTERPRETATION: Improvements in several routine laboratory tests correspond with clinical outcomes in SLE over 12 months. Tests with the strongest associations were discrepant with laboratory tests included in current trial endpoints, and associations were observed across a range of improvement thresholds including incomplete resolution. These findings suggest the need to revise the use of laboratory test results in SLE trial endpoints.

METHODS: Following a systematic literature review, drug survival at 12 and 12-24 months of followup was estimated by summing proportions of patients continuing treatment and dividing by number of studies. Drug survival at ≥ 36 months of followup was estimated through Metaprop.
RESULTS: There were 170 publications included. In the first-line setting, drug survival at 12 months with ETN, IFX, or ADA was 71%, 69%, and 70%, respectively, while at 12-24 months the corresponding rates were 63%, 57%, and 59%. In the second-line setting, drug survival at 12 months with ETN, IFX, or ADA was 61%, 69%, and 55%, respectively, while at 12-24 months the corresponding rates were 53%, 39%, and 43%. Drug survival at ≥ 36 months with ETN, IFX, or ADA in the first-line setting was 59% (95% CI 46-72%), 49% (95% CI 43-54%), and 51% (95% CI 41-60%), respectively, while in the second-line setting the corresponding rates were 56% (95% CI 52-61%), 48% (95% CI 40-55%), and 41% (95% CI 36-47%). Discontinuation of ETN, IFX, and ADA at 36 months of followup was 38-48%, 42-62%, and 38-59%, respectively. Data on CZP and GOL were scarce.
CONCLUSION: After > 12 months of followup, more patients with RA receiving ETN remain on treatment compared with other tumor necrosis factor inhibitors.
METHODS: In this prospective cohort study, we enrolled patients with SLE from 13 international centres that are part of the Asia Pacific Lupus Collaboration. Eligible patients were older than 18 years and fulfilled one of two classification criteria for SLE (1997 American College of Rheumatology criteria or the 2012 Systemic Lupus International Collaborating Clinics criteria). Visits were according to clinical need, with a minimum frequency of one visit per 6 months. We assessed attainment of remission on the basis of the eight DORIS definitions of remission, which varied in terms of serological activity, glucocorticoid use, and use of immunosuppresive agents; attainment of LLDAS; and disease flares at each visit. Irreversible organ damage accrual was recorded annually. Our primary aim was to assess exposure of patients to each of the remission definitions or LLDAS, and the respective association of these states with accrual of irreversible organ damage as the primary outcome measure. Occurrence of disease flares was the key secondary outcome. We used time-dependent Cox proportional hazards models and generalised linear models to assess DORIS definitions of remission and LLDAS in terms of their association with damage accrual and disease flares.
FINDINGS: Between May 1, 2013, and Dec 31, 2016, 1707 patients with SLE were recruited and followed for a mean of 2·2 years (SD 0·9), totalling 12 689 visits. Remission, depending on DORIS definition, was achieved in 581 (4·6%) to 4546 (35·8%) of 12 689 visits. Spending 50% or more of observed time in any remission state was associated with a significant reduction in damage accrual, except for the two most stringent remission definitions, for which the frequency of attainment was lowest. Remission definitions disallowing serological activity were associated with the greatest reductions in disease flares. LLDAS was more attainable than any remission definition and was associated with a similar magnitude of protection from damage accrual and disease flares. Sustained remission and LLDAS were associated with a wider spread of effect sizes for reduction in risk of damage. By analysing patients who met the definition for LLDAS but not remission, we found that LLDAS was significantly associated with reduction in damage accrual, independent of all definitions of remission, except the least stringent.
INTERPRETATION: Attainment of remission was associated with significant reductions in damage accrual and disease flares. LLDAS was more achievable than remission based on the DORIS criteria, but was similarly protective. Remission definitions with less stringency might be insufficiently distinct from LLDAS to substantially affect outcome measures, and further studies are needed to distinguish the protective effects of the various remission definitions.

METHODS: In this prospective cohort study, patients aged 18 years or older with SLE were recruited from 13 centres in eight countries and followed prospectively. Patients with at least two visits over the study period no more than 6 months apart were included in the longitudinal analysis. Patients with no visits in the final year of the study were censored from their last visit. Attainment of the lupus low disease activity state (LLDAS) was assessed at each visit. The primary outcome measure was accrual of irreversible end-organ damage, defined as at least a 1-point increase in the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. We used time-dependent hazard regression models and generalised linear models to measure the association between LLDAS (attainment at any timepoint, cumulative time in LLDAS, and sustained LLDAS) with accrual of irreversible end-organ damage or flare (key secondary outcome). This study is registered with ClinicalTrials.gov, NCT03138941.
FINDINGS: Between May 1, 2013, and Dec 31, 2016, 1707 patients were recruited and followed for a mean of 2·2 years (SD 0·9), totalling 12 689 visits. Attainment of LLDAS at any timepoint was associated with reduction in damage accrual (hazard ratio 0·59, 0·45-0·76; p<0·0001) and subsequent flare (0·65, 95% CI 0·56-0·75; p<0·0001). Cumulative time in LLDAS was associated with improved outcomes: compared with patients with less than 50% of observed time in LLDAS, those with at least 50% of observed time in LLDAS had reduced risk of damage accrual (0·54, 0·42-0·70; p<0·0001) and flare (0·41, 0·35-0·48; p<0·0001). Similarly, increased durations of sustained LLDAS were associated with incremental reductions in the risk of damage accrual. The association of LLDAS with reduced damage accrual was observed regardless of pre-existing damage or disease activity at study entry.
INTERPRETATION: LLDAS attainment is associated with significant protection against flare and damage accrual in SLE. These findings validate LLDAS as an endpoint for clinical studies in SLE.

METHODS: Data from a 13-country longitudinal SLE cohort were collected prospectively between 2013 and 2020. An inception cohort was defined based on disease duration <1 year at enrolment. Patient characteristics between inception and non-inception cohorts were compared. Survival analyses were performed to examine the association between LLDAS attainment and damage accrual and flare.
RESULTS: Of the total 4,106 patients, 680 (16%) were recruited within 1 year of SLE diagnosis (inception cohort). Compared to the non-inception cohort, inception cohort patients were significantly younger, had higher disease activity, used more glucocorticoids, but had less organ damage at enrolment. Significantly fewer inception cohort patients were in LLDAS at enrolment than the non-inception cohort (29.6% vs. 52.3%, p<0.001), but three quarters of both groups achieved LLDAS at least once during follow-up. Limiting analysis only to patients not in LLDAS at enrolment, inception cohort patients were 60% more likely to attain LLDAS (HR = 1.37 (95%CI: 1.16-1.61), p<0.001) than non-inception cohort patients and attained LLDAS significantly faster. LLDAS attainment was significantly protective against flare in both the inception and non-inception cohorts. A total of 88 (13.6%) inception cohort patients accrued damage during a median 2.2 years follow-up.
CONCLUSION: LLDAS attainment is protective from flare in recent onset SLE. Significant protection from damage accrual was not observed, due to low rates of damage accrual in the first years after SLE diagnosis.
METHODS: Subjects from dental and RA clinics were screened. Complete periodontal examinations were performed. Subjects were divided into 4 groups: RA-PD, RA, PD and healthy controls (HC). Questionnaires on characteristics and Malaysian versions of Oral Health Impact Profile (OHIP-14(M)) and Health Assessment Questionnaire (HAQ-DI)) were answered.
RESULTS: A total of 187 subjects were included (29 RA-PD, 58 RA, 43 PD and 57 HC). OHIP-14(M) severity score was highest in the PD group (17.23 ± 10.36) but only significantly higher than the HC group (p
