Treatment of recalcitrant idiopathic orbital inflammation (chronic orbital myositis) with infliximab.

PURPOSE: To report results of treatment with a monoclonal antibody (infliximab) directed against tumor necrosis factor alpha in seven patients with chronic and difficult-to-control idiopathic orbital inflammation (orbital myositis). DESIGN: Observational case series. METHODS: Retrospective data were collected from seven patients who had idiopathic orbital inflammation and who were evaluated at three medical centers. All patients were treated with infliximab after the failure of traditional therapy, which included corticosteroids, radiotherapy, or anti-inflammatory chemotherapeutic agents. RESULTS: All seven patients had a favorable response to treatment with infliximab. One patient with Behcet disease required supplemental oral corticosteroids. Pain, swelling, and need for concomitant corticosteroids were the primary measures of treatment success. Symptoms of comorbid disease in four patients also improved (Crohn disease in two, Behcet disease in one, and psoriasis in one). There were no untoward effects of treatment after a mean follow-up of 15.7 months (range, 4 to 31 months). CONCLUSIONS: Treatment with infliximab appears to offer another therapeutic option in cases of recalcitrant or recurrent idiopathic orbital inflammation in which conventional treatment fails.

Management of extra-articular disease manifestations in rheumatoid arthritis.

PURPOSE OF REVIEW: To discuss the rationale for various treatment strategies in rheumatoid arthritis with extra-articular manifestations, and to review advances in understanding the impact of extra-articular rheumatoid arthritis and its management. RECENT FINDINGS: Recent epidemiologic studies of extra-articular rheumatoid arthritis manifestations have emphasized their major role as predictors of premature mortality in patients with rheumatoid arthritis, and provide a rationale for aggressive ant-rheumatic treatment of extra-articular rheumatoid arthritis. Previous uncontrolled or nonrandomized studies favor the use of cyclophosphamide in patients with systemic rheumatoid vasculitis, and methotrexate in the case of other manifestations of extra-articular rheumatoid arthritis. Recent case reports indicate that patients with rheumatoid lung disease may respond to cyclosporine or tumor necrosis factor inhibitors, and that tumor necrosis factor blocking therapy also may be successful in cases of treatment-resistant vasculitis. By contrast, it has been suggested that tumor necrosis factor inhibitors may induce some manifestations of extra-articular rheumatoid arthritis. Data indicating a high risk of serious infections and cardiovascular disease in patients with extra-articular rheumatoid arthritis underline the importance of carefully monitoring such patients. SUMMARY: Extra-articular rheumatoid arthritis is a serious condition, and rheumatoid arthritis patients with extra-articular manifestations should be aggressively treated and monitored. Advances in the understanding of the pathogenesis of rheumatoid arthritis and developments of new, more specific drugs may be of particular benefit to patients with extra-articular disease.

Histoplasmosis with tenosynovitis of the hand and hypercalcemia mimicking sarcoidosis.

We report on an otherwise healthy 47-year-old male who developed subacute tenosynovitis of the hand associated with night sweats and inguinal lymphadenopathy. He had a past history of granulomatous mediastinal lymphadenitis with positive histoplasmosis serology 11 years previously. Carpal tunnel exploration with biopsy demonstrated granulomatous inflammation. Granulomatous inflammation, hypercalcemia, and an elevated serum angiotensin converting enzyme (ACE) level suggested the diagnosis of sarcoidosis, however histoplasmosis infection could eventually be diagnosed. This unusual presentation of histoplasmosis underscores the fact that the diagnosis of sarcoidosis requires careful exclusion of other causes of granulomatous inflammation, particularly infectious agents. Even in the setting of an elevated ACE level and hypercalcemia, the possibility of an infectious etiology must be considered before establishing a diagnosis of sarcoidosis.

Declining use of orthopedic surgery in patients with rheumatoid arthritis? Results of a long-term, population-based assessment.

OBJECTIVE: To describe the use of orthopedic surgery, including joint replacement surgery, in a well-defined, population-based cohort of patients with rheumatoid arthritis (RA) and to identify characteristics that predict such use. METHODS: A retrospective medical record review was performed of cases of RA incident in Rochester, Minnesota, during the years 1955-1995. All joint surgeries were recorded. RESULTS: Of the total 609 RA incident cases, 242 patients underwent 1 or more (maximum of 20/patient) surgical procedures involving joints during their followup. Overall, this RA cohort had 7.4 surgeries per 100 person-years of followup; the cumulative incidence for joint surgery for RA-related joint disease at 30 years was 33.7% +/- SEM 3.8%. The risk of having a disease-related joint surgery for RA is increased in patients who are women, younger, positive for rheumatoid factor, and have rheumatoid nodules. When adjusted for duration of followup, patients with RA diagnosed after 1985 were significantly less likely to have undergone joint surgery for RA (P < 0.001). Survival of patients who underwent total joint arthroplasty was similar to those who did not. CONCLUSION: Reconstructive surgeries are common in RA, although patients diagnosed after 1985 are less likely to require joint surgery. These findings may reflect trends in medical disease management and have importance for health care resource utilization planning.

Survival in rheumatoid arthritis: a population-based analysis of trends over 40 years.

OBJECTIVE: To evaluate trends in and risk factors for mortality among patients with rheumatoid arthritis (RA) over a 40-year period. METHODS: A population-based inception cohort was assembled from among all Rochester, Minnesota residents ages > or =18 years who were first diagnosed with RA (fulfilling the 1987 American College of Rheumatology criteria for RA) between January 1, 1955 and December 31, 1994. Patients were followed up longitudinally through their entire medical records (including all inpatient and outpatient care by any provider) until death or migration from the county. Survival was described using the Kaplan-Meier method. Observed and expected survival were compared using the log-rank test, and standardized mortality ratios (SMRs) with expected survival were based on the sex and age of the study population and death rates from the Minnesota life tables. Cox proportional hazards models were used to estimate the influence of extraarticular manifestations and comorbidities, controlling for age, sex, body mass index (BMI), smoking, and rheumatoid factor positivity. RESULTS: Survival in this RA cohort was significantly lower than that expected in the population (P < 0.001) over the entire time period. Patients with RA were at significantly higher risk of death, with an SMR of 1.27 (95% confidence interval 1.13-1.41). Excess mortality among women was more pronounced than among men, with SMRs of 1.41 and 1.08, respectively. Presence of > or =1 extraarticular manifestation was the strongest predictor of mortality after adjusting for age, sex, BMI, smoking, and rheumatoid factor positivity. CONCLUSION: Survival in RA patients is significantly lower than expected. The strongest predictors of survival appear to be those related to RA disease complications, specifically, extraarticular manifestations of the disease and comorbidities. More attention should be paid to mortality as an outcome measure in RA.

Incidence and predictors of large-artery complication (aortic aneurysm, aortic dissection, and/or large-artery stenosis) in patients with giant cell arteritis: a population-based study over 50 years.

OBJECTIVE: To determine the incidence and predictors of large-artery complication (aortic aneurysm, aortic dissection, and/or large-artery stenosis) in patients with giant cell arteritis (GCA). METHODS: The cohort of all residents of Olmsted County, Minnesota, in whom GCA was diagnosed between January 1, 1950, and December 31, 1999, was followed up. The incidence of aortic aneurysm, aortic dissection, and large-artery stenosis was determined. Possible predictors and correlates of large-artery complication were assessed. RESULTS: Forty-six incident cases of large-artery complication (representing 27% of the 168 patients in the cohort) were identified. These included 30 incident cases (18%) of aortic aneurysm and/or aortic dissection. Of these cases, 18 (11%) involved the thoracic aorta, with aortic dissection developing in 9 (5%). There were 21 incident cases (13%) of large-artery stenosis. Fifteen patients (9%) had incident cervical artery stenosis, and 6 (4%) had incident subclavian/axillary/brachial artery stenosis. One patient (0.6%) had incident iliac/femoral artery stenosis attributable to GCA. Hyperlipidemia and coronary artery disease were associated with aortic aneurysm and/or dissection (P < 0.05 for both). Cranial symptoms (headache, scalp tenderness, abnormal temporal arteries) were negatively associated with large-artery stenosis (hazard ratio [HR] 0.10 [95% confidence interval (95% CI) 0.03-0.35, P < 0.0005]), as was a higher erythrocyte sedimentation rate (HR 0.80 [95% CI 0.67-0.95, P < 0.05] per 10 mm/hour). CONCLUSION: Large-artery complication is common in GCA. Increased awareness of large-artery complication in GCA, particularly early-occurring aortic dissection, may decrease associated mortality.

Mortality of large-artery complication (aortic aneurysm, aortic dissection, and/or large-artery stenosis) in patients with giant cell arteritis: a population-based study over 50 years.

OBJECTIVE: To determine the mortality of giant cell arteritis (GCA) with large-artery complication compared with that of GCA without large-artery complication. METHODS: An inception cohort of 168 residents of Olmsted County, Minnesota, in whom GCA was diagnosed between January 1, 1950, and December 31, 1999, was followed up. Mortality in patients with incident large-artery complication (aortic aneurysm, aortic dissection, and large-artery stenosis) was determined and compared with that in patients in whom large-artery complication did not develop. RESULTS: No difference in survival was observed between the total group of patients with any type of large-artery complication and patients without large-artery complication or the general population. However, mortality was markedly increased in the 9 patients in whom thoracic aortic dissection developed (median survival 1.1 years [interquartile range 0.2-7.8 years]) compared with that in all other patients with GCA (P < 0.001). No difference in survival was observed between the group of patients with either aortic aneurysm and/or dissection (thoracic and/or abdominal aorta) and the group with GCA without large-artery complication. Survival of patients with GCA and large-artery stenosis was not different from that of patients with GCA without large-artery complication. CONCLUSION: Thoracic aortic dissection in GCA is associated with markedly increased mortality. Overall, mortality in the whole group of patients with GCA with large-artery complication was similar to that in patients with GCA without large-artery complication.

Think clearly, be sincere, act calmly: Adolf Kussmaul (February 22, 1822-May 28, 1902) and his relevance to medicine in the 21st century.

This past year, 2002, marked the 100th anniversary of the death of Adolf Kussmaul. To rheumatologists, he is important as the author of the first case of idiopathic vasculitis, polyarteritis nodosa, which even today is the basis of our understanding of vasculitis. To general internists, his name is linked to Kussmaul's sign and Kussmaul breathing, and to gastroenterologists, he is in many ways-through the development of the gastric pump and the first gastroscope-the father of modern gastroenterology. His reputation as an excellent teacher, his compassion for his patients, and his ability as a clinician scientist led him to be regarded as a giant of 19th century medicine. Kussmaul's life and career, dedicated foremost to reducing human suffering and advancing medicine as a scientific discipline with a strong humanistic foundation, make him a role model for physicians of today.

The utility of positron emission tomography in the evaluation of autoimmune hearing loss.

OBJECTIVE: To evaluate positron emission tomography as an imaging tool in the diagnosis, evaluation, and management of autoimmune inner ear disease. BACKGROUND: Autoimmune inner ear disease is a form of cochleovestibular disease associated with variable hearing loss and vertigo for which no reliable diagnostic tests are available. METHODS: Pilot study of 10 patients with autoimmune inner ear disease and 5 sex-matched and age-matched control subjects without any history of autoimmune inner ear disease, who underwent limited positron emission tomography of the inner ear. Five patients with new or active autoimmune inner ear disease underwent serial positron emission tomography before and after 4 to 6 weeks of a high-dose tapering course of prednisone. The subjects had cranial magnetic resonance imagining, audiometric and vestibular studies, and heat-shock protein (HSP-70) measurements. Reading of the positron emission tomography scans was blinded. RESULTS: Positron emission tomography was normal in 4 of 5 normal control subjects and abnormal in 1 with normal audiometric and vestibular studies and positive HSP-70. Of patients with established and stable autoimmune inner ear disease, 4 of 5 had no positron emission tomography abnormalities and negative HSP-70, and the one with abnormal positron emission tomography shortly thereafter manifested clinically active disease. Of the 5 patients with active autoimmune inner ear disease monitored serially, 4 had an initial abnormal positron emission tomography in at least one ear, which became normal in all but 1 patient after therapy. HSP-70 correlated with disease activity. Only 1 patient with clinically active autoimmune inner ear disease had a normal positron emission tomography before and after therapy (the HSP-70 was positive before therapy and negative after the therapy). CONCLUSIONS: Positron emission tomography, especially when combined with HSP-70 determination, may be a useful technique for assessing disease in patients with autoimmune inner ear disease.

Costimulating aberrant T cell responses by B7-H1 autoantibodies in rheumatoid arthritis.

A pathogenic hallmark of rheumatoid arthritis (RA) is persistent activation of self-reactive CD4(+) T cells. The cause of this aberrant activity remains elusive. We report here detection of autoantibodies against B7-H1, a recently described member of the B7 family, in 29% of patients with RA versus 4% of healthy donors. High-level expression of cell surface B7-H1 are found on activated human CD4(+), CD8(+), and CD45RO(+) T cells. Immobilized autoantibodies to B7-H1 are capable of costimulating the proliferation of CD4(+) T cells in vitro, and the presence of these autoantibodies correlates with active disease status. Using immobilized B7-H1 mAb's and programmed death 1Ig, we demonstrate that engagement of B7-H1 on CD4(+) T cells costimulates proliferation and secretion of IL-10, and subsequently leads to programmed cell death, accompanied with upregulated expression of TNF-related apoptosis-inducing ligand and activation of caspase-3. Taken together with our previous findings, these data indicate a bidirectional signaling role of B7-H1 in T cell costimulation and apoptosis and implicate B7-H1 autoantibodies as contributing to the progression of RA by inducing aberrant T cell responses.
