A case of bilateral rheumatoid pleuritis successfully treated with tocilizumab

Abstract

The patient was a 77-year-old woman diagnosed as having rheumatoid arthritis (RA) in 1973. She was initiated on infliximab therapy in addition to methotrexate administration in 2009. The therapeutic response decreased after the fifth dose of infliximab, and the patient developed rheumatoid pleuritis due to increased RA disease activity. The therapy was switched from infliximab to tocilizumab, which resulted in amelioration of the arthralgias well as pleuritis. Our results suggest that tocilizumab is an effective treatment alternative for the treatment of rheumatoid pleuritis.     

Bilateral vocal fold immobility in a patient with overlap syndrome rheumatoid arthritis/systemic sclerosis

Bilateral vocal fold immobility (BVFI) can be the result of a primary disorder or as an iatrogenic complication of surgery or intubation. Laryngeal involvement can be a rare complication of connective tissue disorders and it usually occurs in association with other symptoms and signs that indicate active disease. We present a case of BVFI in a patient with an overlap syndrome rheumatoid arthritis/systemic sclerosis, referred to our division because of dysphonia and dyspnea. The videolaryngostroboscopy showed the presence of BVFI. Physical examination, blood tests, lung and neck high resolution computed tomography scans did not demonstrate significant abnormalities. She was treated with pulses of intravenous methylprednisolone with slow improvement.     

Spontaneous and aggregated IgG induced rheumatoid factor producing cells in rheumatoid arthritis

Summary Seropositive rheumatoid arthritis (RA) patients were found to have high numbers of spontaneously occurring cells making rheumatoid factor (RF) reactive with human IgG as measured by a RF plaque forming cell (RF-PFC) assay. There was a significant positive correlation between the number of RF-PFC and both disease activity measured by the sedimentation rate and RF titer measured by the RA latex test. Aggregated IgG and pokeweed mitogen were equally effective stimulators of RF-PFC in cultures of RA peripheral blood mononuclear leukocytes. The rheumatoid ratio of helper (T4): suppressor (T8) T lymphocytes was also significantly increased over the ratio of normal controls, but this ratio did not correlate with the number of RF-PFC. Aggregated IgG or immune complexes may be responsible for stimulating RA RF-PFC in vivo.     

Leflunomide-induced polymyositis in a patient with rheumatoid arthritis

Abstract

Although rheumatoid arthritis (RA) and myositis are major autoimmune diseases, co-occurrence of the two is rare. We treated a patient who developed polymyositis (PM) following the treatment of RA with leflunomide. Prednisolone (PSL) in combination with methotrexate (MTX) was effective in managing the PM, but the RA relapsed during the treatment. Based on the clinical course, we suspect that the PM was induced by the leflunomide treatment and suggest that clinicians should consider the possibility of this rare adverse event in cases of cholestyramine-resistant elevation of transaminases.

Spontaneous multiple insufficiency fractures after pelvic abscess and sepsis in a rheumatoid arthritis patient treated with high-load corticosteroid therapy: a case report

We report the unique occurrence and treatment of spontaneous multiple insufficiency fractures after sepsis in a patient with rheumatoid arthritis (RA). The patient was a 53-year-old woman with a 13-year history of RA. Her disease activity was not influenced by a disease-modifying antirheumatic drug (DMARD) regimen that included bucillamine, d-penicillamine, gold, sulfasalazine, and methotrexate. Due to an increased disease activity, her DMARD treatment regimen was changed to leflunomide. She had also undergone corticosteroid therapy with prednisolone ranging from 10 to 15 mg daily over the previous 8 years. She first presented with a wound infection at the surgical site of resection arthroplasty on her left foot, which had caused hematogenous dissemination that led to pelvic abscess and sepsis. For the next 2 years, she experienced multiple insufficiency fractures in parts of the ilium, sacral body, sacral ala, three thoraco-lumbar vertebral bodies (T12, L1, and L2), and subcapital femoral neck without low energy trauma. Postmenopausal osteoporosis, pelvic abscess, sepsis, decreasing daily activity, high RA disease activity, and high-load corticosteroid therapy were considered to be the causes of these fractures. Nonspecific symptoms such as low back pain and fever delayed diagnosis, which may have led to secondary fractures. Although her course after treatment was satisfactory during the study period, we recommend taking repetitive radiographs to detect insufficiency fracture for RA patients with continuing pain and reducing the corticosteroid dose to prevent infection and fracture.     

MRI appearance of retrocalcaneal bursitis and rheumatoid nodule in a patient with rheumatoid arthritis

Rheumatoid arthritis is an autoimmune disorder of unknown etiology characterized by symmetric, erosive synovitis and sometimes multisystem involvement. Rheumatoid nodules have been reported in as many as 20–30% of patients with rheumatoid arthritis; however, they are not commonly seen in the feet. We present magnetic resonance (MR) findings of a rarely seen case of rheumatoid bursitis in the retrocalcaneal bursa associated with a subcutaneous rheumatoid nodule inferior to the calcaneus which histologically confirmed the rheumatoid arthritis. To the best of our knowledge, this is the first case that rheumatoid bursitis in the retrocalcaneal bursa associated with the rheumatoid nodule in the foot was revealed by MR imaging.     

Acute destruction of the hip joints and rapid resorption of femoral head in patients with rheumatoid arthritis

Abstract

We report three rheumatoid arthritis (RA) cases with acute destruction of hip joint and rapid resorption of femoral head. The condition occurred in less than 6 months and closely resembled rapid destructive coxarthrosis. All three patients were postmenopausal women with active RA who had been taking steroids. Two of the patients were taking prednisolone (PSL) of over 20?mg as maximum dose per day, and all patients were resistant to disease-modifying anti-rheumatic drugs (DMARDs). Other than the problems of their hip joints, one had a giant bursitis around the pathological side of the hip joint, another had multiple rheumatoid nodules and skin infarction, and the other suffered from insufficiency fracture of the contralateral femoral subcapital lesion. As a result, all of them had total hip arthroplasty. We recommend taking repetitive radiographs for RA patients with continuing severe hip pain.     

Pericarditis in rheumatoid arthritis

Summary The annual incidence of clinically manifest pericarditis was found to be 0.34% in 157 females and 0.44% in 77 males with rheumatoid arthritis, observed for a mean time of 5.7 years. The development of pericarditis was independent of disease duration, but was related to extensive joint involvement, subcutaneous nodules, and a high Waaler Rose titre. Concomitant pleural effusion was present in four of five patients. Pericarditis in rheumatoid arthritis may indicate a serious prognosis quo ad vitam. Four of the five patients died within eight years, but their age at death was relatively high (62–73 years).     

Acute destruction of the hip joints and rapid resorption of femoral head in patients with rheumatoid arthritis

We report three rheumatoid arthritis (RA) cases with acute destruction of hip joint and rapid resorption of femoral head. The condition occurred in less than 6 months and closely resembled rapid destructive coxarthrosis. All three patients were postmenopausal women with active RA who had been taking steroids. Two of the patients were taking prednisolone (PSL) of over 20 mg as maximum dose per day, and all patients were resistant to disease-modifying anti-rheumatic drugs (DMARDs). Other than the problems of their hip joints, one had a giant bursitis around the pathological side of the hip joint, another had multiple rheumatoid nodules and skin infarction, and the other suffered from insufficiency fracture of the contralateral femoral subcapital lesion. As a result, all of them had total hip arthroplasty. We recommend taking repetitive radiographs for RA patients with continuing severe hip pain.     

Anti-CCP antibodies in rheumatoid arthritis and psoriatic arthritis

Our aim is to assess the prevalence and associated clinical features of anti-CCP (cyclic citrullinated peptide) antibodies for RF (rheumatoid factor)-positive and RF-negative rheumatoid arthritis (RA) and psoriatic arthritis (PsA). In a prospective, cross-sectional, multi-centre study, we determined the titres of anti-CCP antibodies in 208 RA patients (129 RF-positive, 79 RF-negative), 56 PsA patients and 39 healthy controls (HC). Clinical parameters including disease activity (disease activity score 28-DAS28), physical disability (health assessment questionnaire-HAQ), functional capacity (functional class) and radiological erosions were investigated in patients with RA. In PsA patients, clinical and radiological features were determined. Anti-CCP2 antibodies were measured using a second-generation anti-CCP enzyme-linked immunosorbent assay (Euro-Diagnostica, Netherlands). One-hundred four of 129 RF-positive RA (81%), 16 of 79 RF-negative RA (20%), seven of 56 PsA patients (12.5%) and none of the HC had anti-CCP antibodies. RA patients with anti-CCP antibodies had significantly higher disease activity, greater loss of function and more frequent erosive disease than anti-CCP antibody-negative group. In subgroup analysis, anti-CCP antibodies in RF-negative patients were also associated with erosive disease. All PsA patients with anti-CCP antibodies had symmetric arthritis with higher number of swollen joints. The prevalence of anti-CCP antibodies in RF-positive RA patients was significantly higher than in RF-negative RA and PsA patients. Anti-CCP antibodies were also associated with erosive disease in RF-negative RA patients. Both anti-CCP and RF tests were negative in 30% of the patients. Anti-CCP positivity was a frequent finding in PsA and associated with symmetrical polyarthritis.     

Rare copresent rheumatoid arthritis and gout: comparison with pure rheumatoid arthritis and a literature review

Copresent rheumatoid arthritis (RA) and gout is seldom reported. This study summarizes the findings of eight cases of copresent RA and gout and compares them with 31 pure RA cases. Additional reported cases were retrieved from the current literature by Medline search. Patients with copresent RA and gout were older (p = 0.014) and predominantly male (p < 0.01). Synovial fluid, positive for urate crystals, was aspirated most frequently from the knee (five out of eight), followed by the first metatarsophalangeal joint (three out of eight). Serum creatinine and urate levels in the copresent group were significantly higher (p < 0.01, both), and serum hemoglobin was lower (p = 0.04) than those with pure RA. Copresent subjects had much lower percentage of positive rheumatoid factor (RF) tests than patients with pure RA (37.5 vs 80.6%). Only one copresent subject had both RF and anti-cyclic citrullinated peptide antibody. Of copresent subjects, 75% had gouty arthritis before diagnosis of RA, which is consistent with earlier reports. Seven copresent subjects had gout attacks under disease-modifying antirheumatic drug use. This study revealed that polyarthritis negative for RF in a previously gouty patient may be RA and vice versa. This combination occurs more frequently in males. Moreover, anti-CCP antibody examination is not helpful for this diagnosis. Therefore, physicians must obtain synovial fluid for analysis in joints with intense swelling, especially in old RA subjects with renal insufficiency or involvement of lower extremities. Conversely, RA must be considered in gouty patients with polyarticular involvement.     

Subchondral insufficiency fracture of the femoral head after total knee arthroplasty in a patient with rheumatoid arthritis

We report an 80-year-old woman with rheumatoid arthritis (RA) who was found to have subchondral insufficiency fracture of the right femoral head after total knee arthroplasty (TKA). Initially, plain radiographs showed no obvious changes, but magnetic resonance imaging (MRI) revealed an irregular, discontinuous, low-intensity band on T1-weighted images of the right hip. She underwent hemiarthroplasty of the hip. This report describes a rare case of subchondral insufficiency fracture of the femoral head after TKA in a patient with RA.     

Carpal collapse in patients with rheumatoid arthritis

The inflammation of the wrist and carpal collapse play an important role in the deformity of the rheumatoid hand and leads to functional limitation. The aim of this study was to evaluate carpal collapse and related clinical variables in patients with rheumatoid arthritis (RA). Carpal height ratio (CHR) indicating the degree of carpal collapse was measured in 33 female RA patients with a mean age of 41.9±10.3 years and 30 female healthy control subjects with a mean age of 40.5±9.2 years. The normal range of the carpal collapse was defined in our study population and the incidence of carpal collapse was determined. The correlation between carpal collapse and clinical and laboratory variables including pain by visual analog scale, Ritchie articular index, erythrocyte sedimentation rate, C-reactive protein, health assessment questionnaire indicating functional status, and Larsen roentgenological evaluation were determined. Subgroup analyses were also performed in patients with and without carpal collapse. The mean disease duration of the patients was 12.4±5.5 years. The mean CHR index of the patients was significantly lower than in the control group (0.47±4.3 and 0.54±1.4 respectively). CHR <0.48 was defined as carpal collapse in our study group. Seventeen patients (51.5%) had carpal collapse in the patient group. None of the clinical or laboratory variables except levels of disease duration and Larsen score was correlated with carpal collapse as represented by CHR. The best related clinical variable with carpal collapse was found as duration of disease. The mean duration of disease and the Larsen score were significantly higher in patients with carpal collapse than those without collapse. Other clinical parameters and functional status were similar between patients with and without carpal collapse. In conclusion, although various clinical parameters and functional disability in patients with RA may not be correlated with radiological malalignment, the carpal collapse may be more common in RA than is generally recognized.     

Risk factors for osteoporosis and fractures in rheumatoid arthritis

People with rheumatoid arthritis (RA) have both disease-specific risk factors for osteoporosis and fractures in addition to those that affect the general population. Disease specific risks include directly pathogenic auto-antibodies, chronic exposure to systemic inflammation, and joint damage causing early disability. Risk factors that affect the general population which may have a higher prevalence in RA include smoking, calcium and vitamin D deficiency as well as hypogonadism. Additionally, chronic exposure to glucocorticoids results in reduced bone mineral density and body composition changes which can further increase fracture risk. In this review we discuss these risk-factors for osteoporosis as well as factors that may impact fall and fracture risk in people with RA.     

Nodular pulmonary amyloidosis in a patient with rheumatoid arthritis

We describe a 67-year-old white woman with a long-standing active rheumatoid arthritis who refused treatment. Chest roentgenograms performed in 2000 revealed a pulmonary nodule in the mid-left lung. Progression of the nodule was followed annually by computerized tomography (CT). In the last CT in 2002, we observed multiple nodules in both lungs in the absence of lymph gland involvement. The patient was operated by videothoracoscopy to resect one of the pulmonary nodules. Pathological examination of the excised tissue revealed amyloid A-type (AA) amyloidosis. Although pulmonary amyloidosis is rare in patients with systemic AA amyloidosis, we recommend that this possibility be considered when confronted with a patient with these characteristics.     

Cutaneous manifestations associated with rheumatoid arthritis

Rheumatoid arthritis presents various cutaneous manifestations, either specific or nonspecific skin features, which are induced by the activation of inflammatory cells (neutrophils, lymphocytes, macrophages), vasculopathy, vasculitis, acral deformity, drugs, and so on. These include (1) specific findings, (2) findings due to vascular impairment, (3) findings due to immune dysfunction, (4) characteristic neutrophilic conditions, and (5) miscellaneous conditions. On the other hand, some of the specific manifestations show common histopathological features such as palisading granulomas with necrobiosis. It is important to recognize the common and/or uncommon skin conditions of RA for all clinicians associated with RA therapy.     

Organizing pneumonia in a patient with rheumatoid arthritis treated with etanercept

Abstract

Etanercept-induced organizing pneumonia (OP) has not been reported in Japan. We describe the case of a rheumatoid arthritis patient who developed OP during etanercept treatment and discuss the possible mechanisms underlying the development of etanercept-induced OP and the existence of factors that predispose Japanese patients to drug-induced OP.     

Self-care agency in persons with rheumatoid arthritis

Using a framework based on Orem's self-care deficit theory, five hypotheses related to conditioning factors in self-care agency were tested. The study sample consisted of 60 outpatients with a diagnosis of rheumatoid arthritis in a large research hospital. Patients completed the Exercise of Self-Care Agency instrument and the Health Assessment Questionnaire; a physician rated their arthritis severity. Twenty percent of subjects had high scores on self-care agency, 63% had average scores, and 16% had low scores. The conditioning factor of age was not relatedto selfcare agency. However, education and the duration of illness were related to self-care agency in this group of persons with rheumatoid arthritis.     

Bilateral tibia and fibula fractures in a patient with rheumatoid arthritis

A 52-year-old woman with rheumatoid arthritis treated with low-dose steroids developed bilateral distal tibia and fibula fractures over a 15-month period. Her bone density was within osteopenic levels. Such fractures are an unusual but increasingly recognised complication of rheumatoid disease and its treatment, although there is often diagnostic delay. Bilateral fractures are particularly rare. A high level of clinical suspicion is required for early diagnosis. Received: 19 June 2000 / Accepted: 26 January 2001
