Prediction of DAS28-ESR remission at 6 months by baseline variables in patients with rheumatoid arthritis treated with etanercept in Japanese population

We tried to determine which baseline variables are responsible for remission induction at 6 months in unselected rheumatoid arthritis (RA) patients of Japanese population treated with etanercept. One hundred forty-one patients with RA who were administered etanercept were registered. Thirty-four patients were started on etanercept monotherapy, 60 patients on cotherapy with methotrexate (MTX) (MTX cotherapy), and 47 patients on cotherapy with other non-MTX nonbiologic disease-modifying antirheumatic drugs (DMARDs) (non-MTX cotherapy). None of the patients were treated with both MTX and non-MTX nonbiologic DMARDs at entry. Outcome was set as achievement of disease activity score 28 (DAS28)-ESR remission at 6 months. We examined association of gender, DAS at baseline, MTX cotherapy at baseline, non-MTX cotherapy at baseline, and prednisolone use at baseline with achievement of remission at 6 months by logistic regression analysis. All subjects were classified as having high (N = 109) or moderate disease activity (N = 32) at entry. One hundred twenty out of 141 patients (85.1%) continued treatment with etanercept at 6 months. Continuation rate was statistically higher in MTX cotherapy (93.3%) compared with etanercept monotherapy (73.5%), and tended to be higher than with non-MTX cotherapy (85.1%). Logistic regression analysis identified that MTX cotherapy at entry and moderate disease activity at entry were independent variables for remission induction at 6 months. Accordingly, DAS28-ESR at 6 months was significantly lower with MTX cotherapy as compared with etanercept monotherapy or non-MTX cotherapy. To a lesser extent, DAS28-ESR with non-MTX cotherapy at 6 months was lower than with etanercept monotherapy. In this study of unselected patients, use of MTX and moderate disease activity at entry were associated with higher likelihood of response to etanercept. Non-MTX nonbiologic DMARDs may be an alternative in RA patients administrated etanercept who are intolerant to MTX

Utility of a simplified ultrasonography scoring system among patients with rheumatoid arthritis: A multicenter cohort study

ABSTRACT: We aimed to evaluate the utility of a simplified ultrasonography (US) scoring system, which is desired in daily clinical practice, among patients with rheumatoid arthritis (RA) receiving biological/targeted synthetic disease-modifying antirheumatic drugs (DMARDs).A total of 289 Japanese patients with RA who were started on tumor necrosis factor inhibitors, abatacept, tocilizumab, or Janus kinase inhibitors between June 2013 and April 2019 at one of the 15 participating rheumatology centers were reviewed. We performed US assessment of articular synovia over 22 joints among bilateral wrist and finger joints, and the 22-joint (22j)-GS and 22-joint (22j)-PD scores were evaluated as an indicator of US activity using the sum of the GS and PD scores, respectively.The top 6 most affected joints included the bilateral wrist and second/third metacarpophalangeal joints. Therefore, 6-joint (6j)-GS and -PD scores were defined as the sum of the GS and PD scores from the 6 synovial sites over the aforementioned 6 joints, respectively. Although the 22j- or 6j-US scores were significantly correlated with DAS28-ESR or -CRP scores, the correlations were weak. Conversely, 6j-US scores were significantly and strongly correlated with 22j-US scores not only at baseline but also after therapy initiation.Using a multicenter cohort data, our results indicated that a simplified US scoring system could be adequately tolerated during any disease course among patients with RA receiving biological/targeted synthetic DMARDs

Autoimmune Pancreatitis with Primary Sclerosing Cholangitis-like Lesion

Autoimmune pancreatitis is a recently proposed disease entity. It is sometimes associated with other inflammatory diseases such as Sj?gren\u27s disease and sclerosing cholangitis. We report here a case of autoimmune pancreatitis associated with sclerosing cholangitis. The patient was a 74-year-old Japanese male who presented with obstructive jaundice and mild epigastric pain. Computed tomography scan and magnetic resonance cholangiopancreatography showed a diffuse swollen pancreas and poor visualization of the main pancreatic duct. The distal bile ducts were stenotic with marked dilatation of the main and intrahepatic bile ducts. Consequently, a pylorus preserving pancreatoduodenectomy was performed because bile duct carcinoma could not be ruled out. Pathological findings of the removed tissues showed fibrosis with lymphoplasmacytic infiltration in both the choledochus and pancreas head, destruction of pancreatic acinar tissues and obliterative phlebitis. Postoperative laboratory studies showed elevated serum IgG and detection of antinuclear factor. Scattered IgG4-positive plasma cells detected by immunohistochemistry appeared in the pancreas and in the periductal region of the bile duct. This case was finally diagnosed as autoimmune pancreatitis associated with sclerosing cholangitis
