Aim: To identify risk factors for relapse after methotrexate (MTX) dose reduction in rheumatoid arthritis (RA) patients receiving golimumab (GLM)/MTX combination therapy., Method: Data on RA patients ≥20 years old receiving GLM (50 mg) + MTX for ≥6 months were retrospectively collected. MTX dose reduction was defined as a reduction of ≥12 mg from the total dose within 12 weeks of the maximum dose (≥1 mg/wk average). Relapse was defined as Disease Activity Score in 28 joints using C-reactive protein level (DAS28-CRP) score ≥3.2 or sustained (≥ twice) increase of ≥0.6 from baseline., Results: A total of 304 eligible patients were included. Among the MTX-reduction group (n = 125), 16.8% of patients relapsed. Age, duration from diagnosis to the initiation of GLM, baseline MTX dose, and DAS28-CRP were comparable between relapse and no-relapse groups. The adjusted odds ratio (aOR) of relapse after MTX reduction was 4.37 (95% CI 1.16-16.38, P = 0.03) for prior use of non-steroidal anti-inflammatory drugs (NSAIDs), and the aORs for cardiovascular disease (CVD), gastrointestinal disease and liver disease were 2.36, 2.28, and 3.03, respectively. Compared to the non-reduction group, the MTX-reduction group had a higher proportion of patients with CVD (17.6% vs 7.3%, P = 0.02) and a lower proportion of prior use of biologic disease-modifying antirheumatic drugs (11.2% vs. 24.0%, P = 0.0076)., Conclusion: Attention should be given to RA patients with history of CVD, gastrointestinal disease, liver disease, or prior NSAIDs-use when considering MTX dose reduction to ensure benefits outweigh the risks of relapse., (© 2023 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Background: Hepatic lymphorrhea is a rare and serious complication of surgery for digestive tract cancers and is thought to occur as a result of lymph node dissection of the hepatoduodenal ligament. This complication results in the accumulation of lymphatic fluid, which may in turn lead to nutritional disorders, immune deficiency, and circulation insufficiency. However, there is currently no standard strategy for treating this condition., Case Presentation: A 49-year-old woman with alcoholic liver damage underwent laparoscopic distal gastrectomy with lymph node dissection for early gastric cancer. Abundant ascites persisted postoperatively, and the fluid was suspected to indicate hepatic lymphorrhea. The patient was re-admitted on postoperative day 26 due to the onset of a brain infarction caused by dehydration. Various conservative treatments for hepatic lymphorrhea were ineffective. She underwent percutaneous transhepatic lymphangiography and embolization on postoperative day 81, with obvious effect. Computed tomography images demonstrated complete disappearance of ascites., Conclusions: Postoperative hepatic lymphorrhea is a rare and serious complication of radical surgery for digestive tract cancers. The current case suggests that percutaneous transhepatic lymphangiography and embolization may be a rational treatment option when conservative treatments fail., (© 2023. The Author(s).)

This case involved an 82-year-old man with a history of diabetes mellitus and myocardial infarction. He was undergoing treatment with 2 oral antiplatelet agents. The patient presented to our hospital for carcinomatous pyloric stenosis caused by type 4 advanced gastric cancer. Although distal gastrectomy was planned, preoperative coronary angiography revealed triple- vessel coronary artery disease. Therefore, surgery was performed under management of intra-aortic balloon pumping (IABP)therapy. The patient's hemodynamics at the time of the operation were stable, and no perioperative cardiovascular complications occurred. However, the patient was not able to start an oral diet because of impaired swallowing function. Although he underwent daily swallowing rehabilitation, he died of aspiration pneumonia 40 days postoperatively. There are many reports of cancer resection under IABP management for patients with severe heart disease. Because the perioperative hemodynamics were stable in all 21 reported cases of digestive malignant tumor resections in Japan, an IABP is suggested to be very effective for patients with severe heart disease. However, early death has also occurred, as in the present case. Close attention to the indications for IABP therapy is needed, especially in elderly patients, in consideration of not only cancer and heart disease but also preoperative activities of daily living.

Objectives: To evaluate the cost-effectiveness of biologics and methotrexate (MTX) for rheumatoid arthritis (RA) using the number needed to treat (NNT) concept and total actual health care cost., Methods: This study included 121 RA patients with newly prescribed biologics and/or MTX between 2012 and 2017. The NNT was calculated based on the 24 week remission rate of Disease Activity Score in 28 joints using erythrocyte sedimentation rate (DAS28-ESR) and Clinical Disease Activity Index (CDAI)., Results: Remission rates were 76.4% for DAS28-ESR and 45.4% for CDAI in the biologics group and 63.6% and 24.2%, respectively, in the MTX group. The NNT was calculated as 6.4 and 4.2 in the biologics group and 34.2 and 35.2 in the MTX group, respectively. Mean total actual health care costs were 1,044,066 JPY (9835 US$)/24 weeks per treated patient in the biologics group and 75,860 JPY (715 US$)/24 weeks in the MTX group. Although the effectiveness of biologics was superior to MTX from the standpoint of NNT, the mean total health care cost and mean cost per NNT were much higher in the biologics group., Conclusions: Cost-effectiveness is clearly higher for MTX than biologics from the standpoint of mean total health care cost per adjusted NNT under the Japanese health insurance system., (© 2022.

Study Design: A retrospective cohort study., Objective: To examine factors related to severe aggravation of preexisting cervical lesions in patients with rheumatoid arthritis (RA) under current pharmacologic treatments with biologics., Summary of Background Data: Advanced RA cervical lesions carry a risk of irreversible damage to the spinal cord; however, risk factors for aggravation are unclear after the use of biologics became more popular., Methods: Of 166 patients with preexisting cervical lesions at baseline, 87 who had cervical X-ray images taken at baseline and at the final visit (with an interval of more than 1 yr) were evaluated retrospectively. Aggravated instabilities determined at the final visit, were defined as follows: atlantoaxial subluxation (AAS) = atlantodental interval ≧ 10 mm; vertebral subluxation (VS) = a Ranawat value < 10 mm; and subaxial subluxation (SAS) = an anterior vertebral slip ≧ 4 mm or a multilevel slip ≧ 2 mm. Patients were divided into two groups based on the radiographic results: severe aggravation and non-severe aggravation. Explanatory variables were gender, age of RA onset, duration of disease, average observation period, Disease Activity Score 28 based on C-reactive protein (DAS28-CRP) at baseline, drug treatment history, presence of mutilating deformities in the hands, presence of RA-related joint surgery, and the prevalence of each cervical lesion at baseline., Results: The severe group comprised 14 patients (16.1%). There was no significant difference between the two groups with respect to demographic data. Multivariate logistic regression analysis revealed that preexisting SAS lesions (odds ratio: 7.59, 95% confidence interval: 1.16-49.6) and no history of biologic treatment (odds ratio, 0.10; 95% confidence interval, 0.17-0.58) were associated with aggravation., Conclusion: Preexisting SAS lesions were associated with aggravation. Meanwhile, biologics may be effective at preventing aggravation.Level of Evidence: 3., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)

Objective: This study evaluated the effect of surgical intervention on disease activity and factors associated with postoperative disease activity in patients with rheumatoid arthritis (RA). Methods: One hundred and seventy-five patients with RA who underwent a single orthopaedic surgical procedure with 1 year of follow-up were retrospectively reviewed to assess postoperative changes in disease activity using disease activity score in 28 Joints calculated with C-reactive protein (DAS28-CRP). European League against Rheumatology (EULAR) response criteria were used to assess the response to surgical intervention. Results: Overall disease activity was significantly improved after surgery. Therapeutic regimens including biological/targeted-synthetic (b/ts) disease-modifying anti-rheumatic drugs (DMARDs), methotrexate (MTX), and prednisolone (PSL) were not significantly changed 1 year after surgery. Shorter disease duration, surgery of large joints, higher baseline DAS28-CRP, and no use of b/tsDMARDs affected postoperative improvement of disease activity. Multivariate logistic regression analysis revealed that large joint surgery and no preoperative use of b/tsDMARDs were independent factors leading to good response to EULAR criteria after surgery (OR = 2.70; 95% CI, 1.03-7.06; p  < .05, OR = 4.09; 95% CI, 1.50-11.14; p  < .01, respectively). Conclusion: Significant improvement of disease activity after surgical intervention may be expected in patients with RA with large joint surgeries or no preoperative use of b/tsDMARDs.

Objectives: This retrospective, single-center study aimed to compare leg morphology between patients with rheumatoid arthritis (RA) and those with osteoarthritis (OA) undergoing total knee arthroplasty (TKA). Methods: We enrolled 70 RA and 327 OA female patients undergoing TKA. Hip-knee-ankle angle (HKA), femorotibial angle (FTA), valgus correction angle (VCA), and femoral/tibial bowing were measured using full-length radiographs. Femoral bowing of more than 3° or tibial bowing more than 2°, either laterally or medially, was considered substantial. Distribution of these results and the incidence of substantial bowing in RA and OA were compared. Results: HKA, FTA, and VCA were significantly smaller in RA than those in OA. Femoral bowing was significantly smaller in RA (mean angle: 0.04° ± 3.1°) than that in OA (mean angle: 2.1° ± 3.6°) ( p  < .05). In almost half of the patients with RA (48.6%), femoral bowing occurred medially, whereas femoral bowing occurred laterally in approximately three quarters of OA patients (73.1%). Tibial bowing did not differ. The incidence of substantial femoral bowing was significantly lower in RA (27.1%) than that in OA (43.0%) ( p  < .05). Conclusion: RA patients undergoing TKA had different leg morphology than OA patients. These findings have implications for surgical planning.

Objective: This study evaluated the effect of TKA with capsulosynovectomy on disease activity and knee function in patients with RA., Methods: Seventy-six RA patients who underwent primary TKA with more than two years of follow-up were retrospectively reviewed to assess postoperative knee function and disease activity., Results: Postoperative knee function was significantly improved in all clinical scores, and maintained up to 24 months after surgery. RA disease activity was significantly decreased in DAS28-CRP, CDAI, and serum CRP level, and maintained up to 24 months after surgery. Postoperative knee function was negatively correlated with RA disease activity., Conclusions: TKA improves both knee function and disease activity in patients with rheumatoid arthritis.

Background: The mobile bearing knee system was introduced to lessen contact stress on the articular bearing surface and reduce polyethylene wear. The purpose of the current study was to investigate the mid-term results of patients undergoing total knee arthroplasties (TKAs) using Scorpio Plus Mobile Bearing Knee System (Stryker, Mahwah, NJ), and compare the outcomes between patients with osteoarthritis and osteonecrosis (OA·ON group) and patients with rheumatoid arthritis (RA group)., Methods: Eight males and 58 females were followed up for a period of 4.4- 7.6 years from June 1, 2003 to December 31, 2005. There were 53 knees with osteoarthritis, 17 knees with rheumatoid arthritis, and 6 knees with osteonecrosis. Clinical and radiographic follow- up was done using The Japanese Orthopedic Association knee rating score (JOA score) and Knee Society Total Knee Arthroplasty Roentgenographic Evaluation and Scoring System., Results: With regard to the JOA score, there was significant improvement in both groups. The postoperative range of motion was between 0.8°and 116.8° in OA·ON group, and between 0.0° and 113.7° in RA group. There were no significant differences with the radiographic evaluation between two groups. Spontaneous dislocation of a polyethylene insert occurred in one patient, and deep infection was occurred in one patient., Conclusion: There was significant improvement with regard to the clinical and radiographic results of patients undergoing TKAs using the model. The risk of polyethylene insert dislocation related to the mobile bearing TKA is a cause for concern.

Total elbow arthroplasty (TEA) with the GSB III prosthesis was performed in 32 patients (36 elbows) with rheumatoid arthritis between 2001 and 2009. At final follow-up, 31 patients (35 TEAs) were available for clinical and radiological evaluation. The mean follow-up period was 6.3 (2.0-10.3) years, with a minimum follow-up of 2 years. The mean Mayo elbow performance score was significantly improved from 48 points preoperatively to 83 points at final follow-up. The radiographic loosening rate was 14.3% for humeral components and 5.7% for ulnar components. There were 4 cases of intraoperative fracture and 1 case of humeral shaft fracture at 4 months after surgery. The rates for loosening and fracture were relatively low when compared with those in other studies of linked TEA. There were 2 cases of ulnar nerve palsy, but there was no deep infection or triceps disruption. The clinical results of TEA using the GSB III prosthesis in patients with rheumatoid arthritis were found to be satisfactory.

We report a rare case of dystrophic calcinosis in a patient with rheumatoid arthritis in bilateral buttock lesions and the right elbow joint. The calcinosis was surgically removed because it caused severe local pain, possible infection, and difficulty in sitting. Because no recommended standard pharmacotherapy exists for dystrophic calcinosis, surgical treatment should be taken into consideration when calcinosis causes severe local pain or restricts activities of daily life.
