Successful treatment of severe Reiter’s syndrome with etretinate

Abstract

The management of a hyperkeratoitic cutaneous lesion in Reiter’s syndrome (RS) is often unrewarding. Recently, several reports have demonstrated that treatment with etretinate was especially beneficial for severe cutaneous lesion in RS or RS associated with human immunodeficiency virus. We describe a patient with RS whose skin lesions as well as arthritis were successfully treated with oral etretinate.     

Comparison of in-office magnetic resonance imaging versus conventional radiography in detecting changes in erosions after one year of infliximab therapy in patients with rheumatoid arthritis

Abstract

The objective of this study was to compare standard hand radiographs with in-office 0.2?T magnetic resonance imaging (MRI) in monitoring response to therapy in patients with rheumatoid arthritis (RA) who were receiving infliximab, to evaluate the frequency and location of erosions, and to determine if there were differences in outcome based on disease duration at baseline. Patients who satisfied the American College of Rheumatology criteria for RA and were receiving infliximab therapy were evaluated with a baseline and 1-year follow-up MRI. Magnetic resonance images were interpreted by two blinded, board-certified radiologists. Bone erosions were identified as well-defined defects extending through the cortical margin. The mean age of the 48 patients was 58.5 years. The median infliximab dosage was 4?mg/kg. Baseline data showed that 41 patients had abnormal MRIs. The mean time between the baseline and follow-up MRI examinations was 10.5 months. Follow-up MRI revealed regression in 11 patients. Thirty-one patients had both MRIs and radiographs. Magnetic resonance imaging was approximately twice as sensitive as radiography in detecting erosions at baseline. In-office MRI was useful in monitoring disease response after the initiation of infliximab treatment. Magnetic resonance imaging is potentially a very valuable diagnostic tool and prognostic indicator for use in patients with RA.     

Obstacles to the implementation of the treat-to-target strategy for rheumatoid arthritis in clinical practice in Japan

Abstract

Objective. To clarify the obstacles preventing the implementation of the treat-to-target (T2T) strategy for rheumatoid arthritis (RA) in clinical practice.

Methods. A total of 301 rheumatologists in Japan completed a questionnaire. In the first section, participants were indirectly questioned on the implementation of basic components of T2T, and in the second section, participants were directly questioned on their level of agreement and application.

Results. Although nearly all participants set treatment targets for the majority of RA patients with moderate to high disease activity, the proportion who set clinical remission as their target was 59%, with only 45% of these using composite measures. The proportion of participants who monitored X-rays and Health Assessment Questionnaires for all their patients was 44% and 14%, respectively. The proportion of participants who did not discuss treatment strategies was 44%, with approximately half of these reasoning that this was due to a proportion of patients having a lack of understanding of the treatment strategy or inability to make decisions. When participants were directly questioned, there was a high level of agreement with the T2T recommendations.

Conclusion. Although there was a high level of agreement with the T2T recommendations, major obstacles preventing its full implementation still remain.     

Hemophagocytic syndrome in a patient with rheumatoid arthritis

Abstract

A 76-year-old man with rheumatoid arthritis, who had been treated with oral prednisolone and methotrexate, presented with high fever and generalized fatigability. Laboratory data demonstrated marked pancytopenia, which we first regarded as a side effect of methotrexate, and leucovorin was administered with granulocyte-colony stimulating factor and transfusions. Because no recovery was recognized, however, bone marrow aspiration was performed, by which hemophagocytic syndrome was diagnosed. After corticosteroid pulse therapy was initiated, the patient’s symptoms were rapidly attenuated and laboratory data rapidly normalized.     

Hand ultrasound: Comparative study between “no rhupus” lupus erythematosus and rheumatoid arthritis

Abstract

Objective. To compare hand US between systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) patients.

Methods. Hands (1st–5th metacarpophalangeal [MCP] and 1st–5th proximal interphalangeal [PIP] joints) and wrists (radiocarpal and distal radioulnar joints) of 62 “no rhupus” SLE and 60 RA patients were compared through US (linear probe, 6–18 MHz). The findings were compared to clinical, functional, serological outcomes, and disease activity indices.

Results. 2108 and 2040 joint recesses were evaluated in SLE and AR patients, respectively. Synovitis was found in 46.8% and 75% of wrists, 83.9% and 86.7% of MCPs and 58.1% and 70% of PIPs in the SLE and RA groups, respectively. More significant US findings were found in RA group. Greater values of synovitis (mm) in RA group were only found in the joint recesses of wrist (p < 0.001–0.002). In SLE group, US findings were associated with “puffy hands,” Health Assessment Questionnaire score and dynamometry. Twenty-two SLE patients (35.5%) had erosion in any of joints studied. SLE patient subgroup with US erosion was associated with hematological involvement and Jaccoud's arthropathy.

Conclusions. US of “no rhupus” SLE and RA patients is different, especially in wrists. In SLE patients the clinical variable most associated with US findings was “puffy hands.”     

A case with life-threatening interstitial pneumonia associated with bucillamine treatment

Abstract

We report a case of bucillamine-induced interstitial pneumonia accompanied by severe hypoxemia in an 83-year-old woman who had rheumatoid arthritis. Respiratory failure worsened even after withdrawal of bucillamine and administration of high-dose corticosteroids, and mechanical ventilation was required. A review of 15 cases with bucillamine-induced pulmonary injury suggests that advanced age may be associated with the development of severe interstitial pneumonia. Bucillamine can cause corticosteroid-resistant and life-threatening lung injury, especially in the elderly.     

Proposals for leflunomide use to avoid lung injury in patients with rheumatoid arthritis

Abstract

Among the 5,043 consecutive patients registered in the postmarketing surveillance for leflunomide, 61 were reported to have lung injury and 24 died from it. The adjusted multivariate logistic regression analysis of the risk factors showed that preexisting interstitial lung disease posed the greatest risk, as well as loading dose, smoking history, and low body weight of 40 kg or less with odds ratios of 8.17, 3.97, 3.12, and 2.91, respectively. In 12 patients, lung injury developed even 2 months after leflunomide withdrawal. When patients with (n = 9) and without (n = 13) fatal outcome were compared, eight out of the former, and six out of the latter had preexisting interstitial lung disease; the former showed severe hypoxemia, high serum C-reactive protein level, hypoalbuminemia, and continuous lymphocytopenia, and required mechanical ventilation. On the basis of these results and literature review, the committee proposes that leflunomide should only be recommended as a second-line drug, should not be administered to patients with preexisting interstitial lung disease, should also not be administered to patients with smoking history or those with low body weight, and should be administered without loading dose. Careful monitoring is necessary, and when lung injury develops, leflunomide elimination using colestyramine is mandatory.
