RESUMEN

BACKGROUND: While studies have demonstrated that mortality after total hip (THA) and total knee (TKA) arthroplasty is better than the general population, the causes of death are not well established. We evaluated cause-specific mortality after THA and TKA. METHODS: The study included population-based cohorts of patients who underwent THA (N = 2019) and TKA (N = 2259) between 1969 and 2008. Causes of death were classified using the International Classification of Diseases 9th and 10th editions. Cause-specific standardized mortality ratios (SMR) and 95% confidence intervals (CI) were calculated by comparing observed and expected mortality. Expected mortality was derived from mortality rates in the United States white population of similar calendar year, age, and sex characteristics. RESULTS: All-cause mortality was lower than expected following both THA and TKA. However, there was excess mortality due to mental diseases such as dementia following both THA (SMR 1.40, 95% CI 1.08, 1.80) and TKA (SMR 1.49, 95% CI 1.19, 1.85). There was also excess mortality from inflammatory musculoskeletal diseases in THA (SMR 3.50, 95% CI 2.11, 5.46) and TKA (SMR 4.85, 95% CI 3.29, 6.88). When the cohorts were restricted to patients with osteoarthritis as the surgical indication, the excess risk of death from mental diseases still persisted in THA (SMR 1.36, 95% CI 1.02, 1.78) and TKA (SMR 1.52, 95% CI 1.20, 1.91). CONCLUSION: THA and TKA patients experience a higher risk of death from mental and inflammatory musculoskeletal diseases. These findings warrant further research to identify drivers of mortality and prevention strategies in arthroplasty patients.

RESUMEN

OBJECTIVES: To assess the accuracy of dual-energy CT (DECT) for diagnosing gout, and to explore whether it can have any impact on clinical decision making beyond the established diagnostic approach using polarising microscopy of synovial fluid (diagnostic yield). METHODS: Diagnostic single-centre study of 40 patients with active gout, and 41 individuals with other types of joint disease. Sensitivity and specificity of DECT for diagnosing gout was calculated against a combined reference standard (polarising and electron microscopy of synovial fluid). To explore the diagnostic yield of DECT scanning, a third cohort was assembled consisting of patients with inflammatory arthritis and risk factors for gout who had negative synovial fluid polarising microscopy results. Among these patients, the proportion of subjects with DECT findings indicating a diagnosis of gout was assessed. RESULTS: The sensitivity and specificity of DECT for diagnosing gout was 0.90 (95% CI 0.76 to 0.97) and 0.83 (95% CI 0.68 to 0.93), respectively. All false negative patients were observed among patients with acute, recent-onset gout. All false positive patients had advanced knee osteoarthritis. DECT in the diagnostic yield cohort revealed evidence of uric acid deposition in 14 out of 30 patients (46.7%). CONCLUSIONS: DECT provides good diagnostic accuracy for detection of monosodium urate (MSU) deposits in patients with gout. However, sensitivity is lower in patients with recent-onset disease. DECT has a significant impact on clinical decision making when gout is suspected, but polarising microscopy of synovial fluid fails to demonstrate the presence of MSU crystals.

RESUMEN

Oxalate arthropathy is a rare cause of arthritis characterized by deposition of calcium oxalate crystals within synovial fluid. This condition typically occurs in patients with underlying primary or secondary hyperoxaluria. Primary hyperoxaluria constitutes a group of genetic disorders resulting in endogenous overproduction of oxalate, whereas secondary hyperoxaluria results from gastrointestinal disorders associated with fat malabsorption and increased absorption of dietary oxalate. In both conditions, oxalate crystals can deposit in the kidney leading to renal failure. Since oxalate is primarily renally eliminated, it accumulates throughout the body in renal failure, a state termed oxalosis. Affected organs can include bones, joints, heart, eyes, and skin. Since patients can present with renal failure and oxalosis before the underlying diagnosis of hyperoxaluria has been made, it is important to consider hyperoxaluria in patients who present with unexplained soft tissue crystal deposition. The best treatment of oxalosis is prevention. If patients present with advanced disease, treatment of oxalate arthritis consists of symptom management and control of the underlying disease process.

RESUMEN

The objective of this study was to develop European League Against Rheumatism/American College of Rheumatology classification criteria for polymyalgia rheumatica (PMR). Candidate criteria were evaluated in a 6-month prospective cohort study of 125 patients with new-onset PMR and 169 non-PMR comparison subjects with conditions mimicking PMR. A scoring algorithm was developed based on morning stiffness >45 minutes (2 points), hip pain/limited range of motion (1 point), absence of rheumatoid factor and/or anti-citrullinated protein antibody (2 points), and absence of peripheral joint pain (1 point). A score ≥4 had 68% sensitivity and 78% specificity for discriminating all comparison subjects from PMR. The specificity was higher (88%) for discriminating shoulder conditions from PMR and lower (65%) for discriminating RA from PMR. Adding ultrasound, a score ≥5 had increased sensitivity to 66% and specificity to 81%. According to these provisional classification criteria, patients ≥50 years old presenting with bilateral shoulder pain, not better explained by an alternative pathology, can be classified as having PMR in the presence of morning stiffness >45 minutes, elevated C-reactive protein and/or erythrocyte sedimentation rate, and new hip pain. These criteria are not meant for diagnostic purposes.

RESUMEN

The objective of this study was to develop EULAR/ACR classification criteria for polymyalgia rheumatica (PMR). Candidate criteria were evaluated in a 6-month prospective cohort study of 125 patients with new onset PMR and 169 non-PMR comparison subjects with conditions mimicking PMR. A scoring algorithm was developed based on morning stiffness >45 minutes (2 points), hip pain/limited range of motion (1 point), absence of RF and/or ACPA (2 points), and absence of peripheral joint pain (1 point). A score ≥4 had 68% sensitivity and 78% specificity for discriminating all comparison subjects from PMR. The specificity was higher (88%) for discriminating shoulder conditions from PMR and lower (65%) for discriminating RA from PMR. Adding ultrasound, a score ≥5 had increased sensitivity to 66% and specificity to 81%. According to these provisional classification criteria, patients ≥50 years old presenting with bilateral shoulder pain, not better explained by an alternative pathology, can be classified as having PMR in the presence of morning stiffness>45 minutes, elevated CRP and/or ESR and new hip pain. These criteria are not meant for diagnostic purposes.

RESUMEN

OBJECTIVE: Understanding of the personal risks for rheumatoid arthritis (RA) and other rheumatic diseases remains poor, despite advances in knowledge with regard to their pathogenesis, therapeutics, and clinical impact, in part because the personal lifetime risk of developing these diseases is unknown. This study was undertaken to estimate the lifetime risk of RA, as well as other inflammatory autoimmune rheumatic diseases, including systemic lupus erythematosus, psoriatic arthritis, polymyalgia rheumatica (PMR), giant cell arteritis, ankylosing spondylitis, and Sjögren's syndrome, and to provide an overall estimate of the risk of developing inflammatory autoimmune rheumatic disease over a lifetime. METHODS: Using the incidence rates obtained from our population-based studies of rheumatic diseases among residents of Olmsted County, Minnesota, and mortality rates from life tables for the general population, we estimated the sex-specific lifetime risk of rheumatic disease. RESULTS: The lifetime risk of RA developing in US adults was 3.6% for women and 1.7% for men, and the lifetime risk of rheumatoid factor-positive RA was 2.4% for women and 1.1% for men. The second most common inflammatory autoimmune rheumatic disease was PMR, with a lifetime risk of 2.4% for women and 1.7% for men. The overall lifetime risk of inflammatory autoimmune rheumatic disease was 8.4% for women and 5.1% for men. CONCLUSION: One in 12 women and 1 in 20 men will develop an inflammatory autoimmune rheumatic disease during their lifetime. These results can serve as useful guides in counseling patients regarding their lifetime risk of these conditions and have important implications regarding disease awareness campaigns.

RESUMEN

Gout has been recognized for centuries but is also a modern day scourge. It is the most common type of inflammatory arthritis in men and appears to be increasing in both incidence and prevalence (Arromdee et al. in J Rheumatol 29(11):2403-2406, 2002). Despite these facts, few advances have been made in the diagnosis and treatment of gout for over 50 years. Difficult cases of gout challenge available therapeutic options. It is only recently that the Food and Drug Administration has approved febuxostat as a treatment option for patients intolerant of allopurinol. We describe a difficult case of tophaceous gout notable for several reasons: utilization of rasburicase as uricolytic treatment to dramatically reduce tissue urate burden; treatment of gout flares with interleukin-1ß inhibition; and quantification of tissue urate with novel dual energy computed tomography technology before and after uricolytic therapy.

RESUMEN

Tocilizumab (Actemra; Genentech, Inc) is the first biologic therapy targeting the cytokine interleukin 6 (IL-6). It is a humanized monoclonal immunoglobulin G1 antibody against the α-chain of the IL-6 receptor that prevents the binding of IL-6 to membrane-bound and -soluble IL-6 receptor. It was approved by the US Food and Drug Administration in January 2010 for rheumatoid arthritis refractory to other approved therapies and in April 2011 for systemic juvenile idiopathic arthritis. It has been used as an off-label treatment in many autoimmune diseases, where IL-6 plays a major role in pathogenesis. We report a case of refractory systemic lupus erythematosus in a 22-year-old woman with recurrent high-grade fever, polyarthritis, diffuse rash with urticarial vasculitis, and tumid lupus who did not respond to topical corticosteroids, photoprotection, antimalarials, methotrexate, anakinra, mycophenolate mofetil, etanercept, and intravenous immunoglobulin therapy. Symptoms recurred after corticosteroid tapers below 10 mg. She was noted to have an elevated IL-6 level, and tocilizumab was started. She responded favorably with remission of fever, arthritis, and skin manifestations and was able to taper corticosteroid therapy successfully.

RESUMEN

Inflammatory processes, such as an infection or drug reaction, can cause antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV). Although quite rare, AAV may occur with SARS-coronavirus disease 2019 (COVID-19) antigenic exposure, either from infection or immunization. We present two cases of AAV: one that developed after COVID-19 infection presenting as diffuse alveolar haemorrhage and another that developed shortly after vaccination, presenting as granulomatous pulmonary nodules. Both patients improved with supportive care and immunosuppressive therapies. This adverse event appears to be a very rare complication of COVID-19 infection or vaccination. Early diagnosis of AAV is important because immunosuppressive therapy may improve patient outcomes.

RESUMEN

The objective of this study is to describe the clinical features and outcomes of patients with the newly defined vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome. Nine men with somatic mutations in the UBA1 gene were identified; the most frequent variant was p.Met41Thr (7 of 9, 78%). The median age at VEXAS diagnosis was 74 (67, 76.5) years, and patients had a median duration of symptoms for 4 years before diagnosis. Refractory constitutional symptoms (88%), ear and nose chondritis (55%), and inflammatory arthritis (55%) were common clinical features. Vasculitis was noted in 44%. All patients had significantly elevated inflammatory markers and macrocytic anemia. Thrombocytopenia was present in 66% at diagnosis of VEXAS. Eight patients had bone marrow biopsies performed. All bone marrows were hypercellular, and there was vacuolization of the erythroid (100%) or myeloid precursors (75%). Glucocorticoids attenuated symptoms at prednisone doses ≥20 mg per day, but no other immunosuppressive agent showed consistent long-term control of disease. One patient with coexisting plasma-cell myeloma received plasma-cell-directed therapy with improvement of the inflammatory response, which is a novel finding. In conclusion, VEXAS syndrome is a clinically heterogeneous, treatment-refractory inflammatory condition caused by somatic mutation of the UBA1 gene. Patients often present with overlapping rheumatologic manifestations and persistent hematologic abnormalities. As such, internists and subspecialists, including pathologists, should be aware of this condition to avert diagnostic delay, now that the etiology of this syndrome is known.

RESUMEN

OBJECTIVE: To examine whether a change in the presentation of incident gout happened over the last 20 years and to determine the risk of subsequent gout flares after an initial gout attack. METHODS: All incident cases of gout were identified among residents of Olmsted County, Minnesota, diagnosed in 1989-1992 and 2009-2010 according to the earliest date fulfilling the 1977 American Rheumatism Association preliminary criteria, or the New York or Rome criteria for gout. Patients in both cohorts were then followed for up to 5 years. Cumulative incidence and person-year methods were used to compare flare rates, and conditional frailty models were used to examine predictors. RESULTS: A total of 429 patients with incident gout (158 patients in 1989-1992 and 271 patients in 2009-2010) were identified and followed for a mean of 4.2 years. The majority of patients were male (73%) and the mean age (SD) at gout onset was 59.7 (17.3) years. Classic podagra decreased significantly from 74% to 59% (p < 0.001). Cumulative incidence of first flare was similar in both cohorts (62% vs 60% by 5 yrs in 1989-1992 and 2009-2010, respectively; p = 0.70), but overall flare rate was marginally higher in 2009-2010 compared to 1989-1992 (rate ratio: 1.24). Hyperuricemia (HR 1.59) and kidney disease (HR 1.34) were significant predictors of future flares. CONCLUSION: Gout flares were common in both time periods. Hyperuricemia and kidney disease were predictors of future flares in patients with gout. Podagra as a presentation of gout has become relatively less frequent in recent years.

RESUMEN

OBJECTIVE: To identify longitudinal predictors of discordance between patients with rheumatoid arthritis (RA) and their health care providers, where patient global assessment of disease activity is substantially higher than provider global assessment. METHODS: This retrospective case-control study included 102 cases with positive discordance (i.e., ≥25 mm between patient and provider global assessments) and 102 controls without discordance who were matched for age, sex, RA duration, and Clinical Disease Activity Index (CDAI) score. Data were collected at the baseline visit (date of diagnosis or earliest available visit), the index visit (participation in a previous cross-sectional study), and at up to 11 additional visits before the index visit. Data included patient characteristics, disease activity measures, Disease Activity Score in 28 joints (3-variable) using the C-reactive protein level (DAS28-CRP), and medications. Data were analyzed by using linear and logistic regression models with smoothing splines for nonlinear trends. RESULTS: Overall, the mean age was 63 years, 75% of patients were female, and the mean RA duration was 10 years. Compared with controls, cases had higher rates of discordant visits during the 4 years before the index visit, and they had a higher CDAI score and DAS28-CRP earlier in the disease course. Cases more frequently had antinuclear antibodies, nonerosive disease, prior depression, or prior use of antidepressants or fibromyalgia medications. Disease-modifying medication use was not different between cases and controls. CONCLUSION: The findings inform new hypotheses about the relationships of disease activity and antinuclear antibodies to the later occurrence of positive discordance among patients with RA.

RESUMEN

Previously, we demonstrated in test and validation cohorts that type I IFN (T1IFN) activity can predict non-response to tumor necrosis factor inhibitors (TNFi) in rheumatoid arthritis (RA). In this study, we examine the biology of non-classical and classical monocytes from RA patients defined by their pre-biologic treatment T1IFN activity. We compared single cell gene expression in purified classical (CL, n = 342) and non-classical (NC, n = 359) monocytes. In our previous work, RA patients who had either high IFNß/α activity (>1.3) or undetectable T1IFN were likely to have EULAR non-response to TNFi. In this study comparisons were made among patients grouped according to their pre-biologic treatment T1IFN activity as clinically relevant: "T1IFN undetectable (T1IFN ND) or IFNß/α >1.3" (n = 9) and "T1IFN detectable but IFNß/α ≤ 1.3" (n = 6). In addition, comparisons were made among patients grouped according to their T1IFN activity itself: "T1IFN ND," "T1IFN detected and IFNß/α ≤ 1.3," and "IFNß/α >1.3." Major differences in gene expression were apparent in principal component and unsupervised cluster analyses. CL monocytes from the T1IFN ND or IFNß/α >1.3 group were unlikely to express JAK1 and IFI27 (p < 0.0001 and p 0.0005, respectively). In NC monocytes from the same group, expression of IFNAR1, IRF1, TNFA, TLR4 (p ≤ 0.0001 for each) and others was enriched. Interestingly, JAK1 expression was absent in CL and NC monocytes from nine patients. This pattern most strongly associated with the IFNß/α>1.3 group. Differences in gene expression in monocytes among the groups suggest differential IFN pathway activation in RA patients who are either likely to respond or to have no response to TNFi. Additional transcripts enriched in NC cells of those in the T1IFN ND and IFNß/α >1.3 groups included MYD88, CD86, IRF1, and IL8. This work could suggest key pathways active in biologically defined groups of patients, and potential therapeutic strategies for those patients unlikely to respond to TNFi.

RESUMEN

BACKGROUND: In population-based estimates of disease, the incidence of ANCA-associated vasculitides is increasing, with the peak age of onset in middle aged and older adults. Clinical characteristics of the very elderly have not been fully elucidated. METHODS: Patients who met the criteria for Wegener granulomatosis and microscopic polyangiitis were included in the study. The following characteristics were analyzed by retrospective review: time interval from first symptoms to date of diagnosis, age at diagnosis, laboratory values on initial presentation, and Birmingham Vasculitis Activity Score when diagnosed. RESULTS: Patients >75 years old were more often female, had fewer ear, nose, or throat symptoms, and had lower hemoglobin values. At date of latest follow-up, 40% of the older patients died compared with 11% of the younger cohort (P = 0.0006). Of the deceased elderly patients, nearly one-half died within 6 months. Age >75 carried an elevated risk of mortality (hazard ratio = 2.69, 95% confidence interval = 1.55-4.96; P = 0.0005) as did elevated serum creatinine (hazard ratio = 1.25 per 1 mg/dL, 95% confidence interval = 1.06-1.43; P = 0.0109). Survival was worse in those presenting with Birmingham Vasculitis Activity Score >20 and those >75-year-old. CONCLUSION: The clinical presentation of ANCA-associated vasculitis is relatively similar among elderly and younger patients. In patients aged 75 years or older, ANCA vasculitis is associated with higher mortality, and related to the presence of renal involvement. Elderly patients have a greater risk for death within the first 6 months after diagnosis.

RESUMEN

OBJECTIVE: To assess in-hospital gout flares in patients with gout. METHODS: Hospitalizations were evaluated for gout flares in a cohort of Olmsted County, Minnesota, residents with incident gout in 1989-1992 or 2009-2010. RESULTS: There were 429 patients followed up to 5 years. Of these, 169 patients experienced 454 hospitalizations. Hospitalization rates increased without reaching statistical significance from 1989-1992 to 2009-2010 [rate ratio (RR) 1.19, 95% CI 0.98-1.45]. The gout flare rate increased significantly during hospitalization (RR 10.2, 95% CI 6.8-14.5). In-hospital gout flare increased the average hospital stay by 1.8 days (p < 0.001). CONCLUSION: Hospitalization increased the risk of gout flares 10-fold. In-hospital gout flares were associated with longer hospitalization.

RESUMEN

OBJECTIVE: To examine the incidence of gout over the last 20 years and to evaluate possible changes in associated comorbid conditions. METHODS: The medical records were reviewed of all adults with a diagnosis of incident gout in Olmsted County, Minnesota, USA, during 2 time periods (January 1, 1989-December 31, 1992, and January 1, 2009-December 31, 2010). Incident cases had to fulfill at least 1 of 3 criteria: the American Rheumatism Association 1977 preliminary criteria for gout, the Rome criteria, or the New York criteria. RESULTS: A total of 158 patients with new-onset gout were identified during 1989-1992 and 271 patients during 2009-2010, yielding age- and sex-adjusted incidence rates of 66.6/100,000 (95% CI 55.9-77.4) in 1989-1992 and 136.7/100,000 (95% CI 120.4-153.1) in 2009-2010. The incidence rate ratio was 2.62 (95% CI 1.80-3.83). At the time of their first gout flare, patients diagnosed with gout in 2009-2010 had higher prevalence of comorbid conditions compared with 1989-1992, including hypertension (69% vs 54%), diabetes mellitus (25% vs 6%), renal disease (28% vs 11%), hyperlipidemia (61% vs 21%), and morbid obesity (body mass index ≥ 35 kg/m2; 29% vs 10%). CONCLUSION: The incidence of gout has more than doubled over the recent 20 years. This increase together with the more frequent occurrence of comorbid conditions and cardiovascular risk factors represents a significant public health challenge.

RESUMEN

BACKGROUND: Discordance between patients with rheumatoid arthritis (RA) and their rheumatology health care providers is a common and important problem. The objective of this study was to perform a comprehensive clinical evaluation of patient-provider discordance in RA. METHODS: A cross-sectional observational study was conducted of consecutive RA patients in a regional practice with an absolute difference of ≥ 25 points between patient and provider global assessments (possible points, 0-100). Data were collected for disease activity measures, clinical characteristics, comorbidities, and medications. In a prospective substudy, participants completed patient-reported outcome measures and underwent ultrasonographic assessment of synovial inflammation. Differences between the discordant and concordant groups were tested using χ2 and rank sum tests. Multivariable logistic regression was used to develop a clinical model of discordance. RESULTS: Patient-provider discordance affected 114 (32.5%) of 350 consecutive patients. Of the total population, 103 patients (29.5%) rated disease activity higher than their providers (i.e., 'positive' discordance); only 11 (3.1%) rated disease activity lower than their providers and were excluded from further analysis. Positive discordance correlated with negative rheumatoid factor and anticyclic citrullinated peptide antibodies, lack of joint erosions, presence of comorbid fibromyalgia or depression, and use of opioids, antidepressants, or anxiolytics, or fibromyalgia medications. In the prospective study, the group with positive discordance was distinguished by higher pain intensity, neuropathic type pain, chronic widespread pain and associated polysymptomatic distress, and limited functional health status. Depression was found to be an important mediator of positive discordance in low disease activity whereas the widespread pain index was an important mediator of positive discordance in moderate-to-high disease activity states. Ultrasonography scores did not reveal significant differences in synovial inflammation between discordant and concordant groups. CONCLUSIONS: The findings provide a deeper understanding of patient-provider discordance than previously known. New insights from this study include the evidence that positive discordance is not associated with unrecognized joint inflammation by ultrasonography and that depression and fibromyalgia appear to play distinct roles in determining positive discordance. Further work is necessary to develop a comprehensive framework for patient-centered evaluation and management of RA and associated comorbidities in patients in the scenario of patient-provider discordance.

RESUMEN

OBJECTIVES: To analyze the cardiac findings that necessitate surgery in patients with relapsing polychondritis (RP) and to compare our results to cases in the literature. MATERIAL AND METHODS: A systematic overview of the literature was completed with the addition of cases of RP from the Mayo patient population that necessitated cardiac surgery. RESULTS: Thirty-three patients were identified (25 from the literature and 8 from the Mayo patient population). Nine patients (27%) were female, 22 (67%) were male, and sex was not stated for 2 patients (6%). The patient age ranged from 17 to 69 years (mean +/- SD, 42.5 +/- 15.7 years). At operation, 30 patients (91%) had aortic regurgitation, 21 (64%) had aortic root disease, and 13 (39%) had mitral regurgitation. The most common surgical procedure performed was aortic valve replacement in 12 patients (36%). The most common complications were death in 12 patients (36%) and prosthetic valve dehiscence in 4 patients (12%). CONCLUSIONS: Cardiac involvement is more prominent in the male population and requires more invasive procedures. Aortic valve replacement with composite graft replacement of the ascending aorta along with coronary artery ostial reimplantation should be considered in these patients. Postsurgical valvular complications include prosthetic dehiscence, paravalvular leakage, mediastinitis, and heart failure, and these complications are associated with postoperative corticosteroid therapy. Initiation of second-line immunosuppressive therapy should be substituted for corticosteroids after cardiac surgery.
