RESUMEN
BACKGROUND: Short-term randomized trials suggest that a 500 mg/d vitamin C supplement reduces serum urate, whereas observational studies show vitamin E is inversely associated with gout risk. OBJECTIVES: We evaluated the effect of supplemental vitamin C (prespecified primary exposure) and vitamin E (prespecified secondary exposure) on new diagnoses of gout. METHODS: We performed a post hoc analysis of data from the Physicians' Health Study II, a randomized, double-blind, placebo-controlled factorial trial of randomized vitamin C (500 mg/d) and vitamin E (400 IU every other day). The primary outcome was new gout diagnoses, self-reported at baseline and throughout the follow-up period of ≤10 y. RESULTS: Of 14,641 randomly assigned male physicians in our analysis, the mean age was 64 ± 9 y; 1% were Black, and 6.5% had gout prior to randomization. The incidence rate of new gout diagnoses during follow-up was 8.0 per 1000 person-years among those assigned vitamin C compared with 9.1 per 1000 person-years among those assigned placebo. The vitamin C assignment reduced new gout diagnoses by 12% (HR: 0.88; 95% CI: 0.77, 0.99; P = 0.04). These effects were greatest among those with a BMI <25 kg/m 2 (P-interaction = 0.01). Vitamin E was not associated with new gout diagnoses (HR: 1.05; 95% CI: 0.92, 1.19; P = 0.48). CONCLUSIONS: Vitamin C modestly reduced the risk of new gout diagnoses in middle-aged male physicians. Additional research is needed to determine the effects of higher doses of vitamin C supplementation on serum urate and gout flares in adults with established gout.The Physicians' Health Study II is registered at clinicaltrials.gov (identifier: NCT00270647).

Systemic lupus erythematosus (SLE) is an autoimmune inflammatory condition that may involve multiple organ systems. Although the antinuclear antibody (ANA) test is positive in nearly every case of SLE, it is not specific for this disease and must be interpreted in the appropriate clinical context. Key features that warrant ANA testing include unexplained multisystem inflammatory disease, symmetric joint pain with inflammatory features, photosensitive rash, and cytopenias. ANA staining patterns and more specific autoantibody testing may be helpful in diagnosis of suspected SLE or ANA-associated disease. For patients with nonspecific symptoms, such as malaise and fatigue, ANA testing is of limited value.

BACKGROUND: Septic arthritis (SA) is associated with significant morbidity and mortality. Delayed or inadequate treatment may result in joint destruction, osteomyelitis and sepsis. Like other types of infection, the causative agents of SA may have changed over time. Early targeted intervention is important in cases of SA and can be achieved only by understanding the current trends in the microbiology of SA. OBJECTIVES: To determine the trends in the microbiology of SA over the last two decades. METHODS: We conducted a retrospective study including all patients 18 and older with culture positive, surgically treated, native joint septic arthritis (NJSA), admitted to a single tertiary medical centre in Boston between the years of 1997 and 2015. We excluded cases of osteomyelitis and septic bursitis. We focused our analysis on the microbiology data which included synovial fluid gram stain and culture, blood cultures and synovial biopsy cultures. RESULTS: Among 260 cases, the most common bacteria isolated were Methicillin Sensitive Staphylococcus aureus (MSSA, 36%), Methicillin Resistant Staphylococcus aureus (MRSA, 17.6%), Coagulase Negative Staphylococci (CoNS, 13%) and Group B Streptococcus (GBS, 7.3%). Trends in the rates of these bacteria demonstrated no significant variation. The knee was the most common joint affected, followed by the shoulder and hip. Shoulder SA was most commonly caused by MRSA while MSSA was the leading causative organism in other joints. GBS was a causative bacterium in shoulder SA significantly more often than in knee or hip infections. CONCLUSIONS: Although no significant trends were noted in the microbiology of SA over nearly 2 decades, we observed meaningful findings regarding shoulder SA as MRSA was the most common bacterial because of SA in this joint. Prompt joint aspiration, microbiologic testing of synovial fluid and empiric antibiotic therapy that covers MRSA may improve outcomes in SA.

OBJECTIVE: Hydroxychloroquine (HCQ) is commonly prescribed for the treatment of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and other rheumatic diseases. To limit retinal toxicity, the 2016 American Academy of Ophthalmology (AAO) guidelines recommended limiting the HCQ dose to 5 mg/kg/day or less. Our objective was to develop a quality improvement program to improve adherence to these guidelines. METHODS: We performed a retrospective analysis of 801 adult patients receiving HCQ for SLE and RA in a single academic rheumatology practice. In 2018, we calculated weight-based doses of HCQ at two time points at least 6 months apart. We surveyed provider opinions regarding the 2016 AAO guidelines and implemented a quality improvement intervention during which dosing data were shared with all prescribers (individually and in aggregate) and nurse-aided decision support was provided for HCQ refill requests. One year after the initial analysis and intervention, we again assessed weight-based doses of HCQ for the 674 patients still taking HCQ. RESULTS: At both measured time points during 2018, 22.8% of patients received doses greater than 5 mg/kg/day. For 60% of those patients, the dose of HCQ was reduced to 5 mg/kg/day or less by the study end. Between the second time point in 2018 and the postintervention time point in 2019, there was a statistically significant increase in the proportion of patients receiving of dose of 5 mg/kg/day or less (from 74% to 87%; P < 0.0001). CONCLUSION: We observed a significant increase in adherence with current AAO guidelines for weight-based HCQ dosing after providing feedback to providers regarding their prescribing data and reviewing weight-based dosing prior to refilling prescriptions.
RESUMEN
Background: Peri-prosthetic joint infection (PJI) is a debilitating and costly complication of joint replacement. Synovial fluid cultures are negative in up to 25% of PJI cases. The purpose of this study was to compare the clinical characteristics and outcomes of culture negative and culture positive PJI. Patients and Methods: We conducted a retrospective study including all patients aged 18 and older admitted to a single tertiary-care hospital between 1998 and 2015 diagnosed with PJI and treated with antibiotic agents and surgery. Results: One hundred ninety-six patients with PJI were identified; 48 (24.5%) were culture-negative (CN) and 148 (75.5%) were culture-positive (CP). The groups were similar in age and presence of associated comorbidities. Fever was more common among the CP patients (CN, 23.8%; CP, 38.4%; p = 0.03) as was sepsis defined by Sepsis-2 criteria (CN, 12.8%; CP, 28.7%; p = 0.03). Patients who were CP had higher synovial white blood cell (WBC) count (CN, 30,500 per milliliter; CP, 95,400 per milliliter; p < 0.01), a longer length of stay (CN, 3.8%; CP,7.9%; p = 0.02), and fewer alternative diagnoses established within one year (CN, 25.0%; CP, 2.7%; p < 0.01). Our logistic regression models also found that CP patients had an adjusted odds ratio (OR) of 2.59 for rehabilitation placement with 95% confidence interval (CI) of 1.15-5.83 and adjusted OR of 0.04 for an alternative diagnosis within one year with 95% CI, 0.009-0.22 compared with their CN counterparts. Conclusions: This study suggests that patients with CN PJI have less severe disease, better outcomes, and higher rates of alternative diagnoses within one year.

BACKGROUND: Dietary recommendations to prevent gout emphasize a low-purine diet. Recent evidence suggests that the Dietary Approaches to Stop Hypertension (DASH) diet reduces serum urate while also improving blood pressure and lipids. OBJECTIVE: To compare the effects of DASH-style diets emphasizing different macronutrient proportions on serum urate reduction. METHODS: We conducted a secondary analysis of the Optimal Macronutrient Intake Trial to Prevent Heart Disease feeding study, a 3-period, crossover design, randomized trial of adults with prehypertension or hypertension. Participants were provided with 3 DASH-style diets in random order, each for 6 wk. Each DASH-style diet emphasized different macronutrient proportions: a carbohydrate-rich (CARB) diet, a protein-rich (PROT) diet, and an unsaturated fat-rich (UNSAT) diet. In the PROT diet, approximately half of the protein came from plant sources. We compared the effects of these diets on serum urate at weeks 4 and 6 of each feeding period. RESULTS: Of the 163 individuals included in the final analysis, the mean serum urate at baseline was 5.1 mg/dL. Only the PROT diet reduced serum urate from baseline at the end of the 6-wk feeding period (-0.16 mg/dL; 95% CI: -0.28, -0.04; P = 0.007). Neither the CARB diet (-0.03 mg/dL; 95% CI: -0.14, 0.09; P = 0.66) nor the UNSAT diet (-0.01 mg/dL; 95% CI: -0.12, 0.09; P = 0.78) reduced serum urate from baseline. The PROT diet lowered serum urate by 0.12 mg/dL (95% CI: -0.20, -0.03; P = 0.006) compared with CARB and by 0.12 mg/dL (95% CI: -0.20, -0.05; P = 0.002) compared with UNSAT. CONCLUSIONS: A DASH-style diet emphasizing plant-based protein lowered serum urate compared with those emphasizing carbohydrates or unsaturated fat. Future trials should test the ability of a DASH-style diet emphasizing plant-based protein to lower serum urate and prevent gout flares in patients with gout. This trial was registered at clinicaltrials.gov as NCT00051350.

RATIONALE, AIMS AND OBJECTIVES: Approximately 20 000 cases of septic arthritis (SA) occur in the U.S. yearly. We examined whether gender-related differences exist in the presentation, management, and outcomes of patients with native joint septic arthritis (NJSA). METHODS: This was a retrospective study of medical files of patients aged 18 years and older admitted between 1998 and 2015 to a single tertiary care hospital and diagnosed with NJSA. All study subjects had positive synovial fluid or blood cultures and each was managed surgically. Patients' charts were reviewed for demographics, comorbidities, clinical presentations, microbiology profiles, management, and outcomes. Cases of osteomyelitis, septic bursitis, prosthetic joint, and culture-negative SA were excluded. RESULTS: Of 324 NJSA patients, those who were female (n = 130; 40.1%) were significantly older at presentation than males (mean age: 63.6 vs 58.3; P = .006). Prior joint pathology was more common amongst females, including osteoarthritis (20.8% vs 12.9%; P = .04) and rheumatoid arthritis (10% vs 3.6%; P = .03). Female patients had a higher frequency of hip involvement (17.7% vs 10.8%; P = .05). No differences were observed in clinical presentations, culture results, medical management, or outcomes between genders. CONCLUSIONS: Compared to men, women with NJSA presented at an older age and had more prior joint pathology and a higher frequency of hip involvement. These differences, however, had no significant impact on the clinical presentation, medical management, or outcomes of NJSA.

Background: Patients with culture-negative septic arthritis patients are often treated surgically but might be successfully managed medically. We compared clinical characteristics and outcomes in patients with culture negative and culture positive native joint monoarticular septic arthritis.Methods: This retrospective study included all patients age ≥18 years admitted to a single, tertiary-care hospital between 1998 and 2015 with native joint monoarticular SA and treated with antibiotics and surgery.Results: Of 306 patients, 85 had negative and 221 had positive cultures. Mean C-reactive protein (p < .01) and mean percentage of peripheral polymorphonuclear cells (p = .01) were higher in culture-positive patients who had higher intensive care unit admission rates (16.7% vs. 4.7%, respectively, [p < .01]), longer length of hospital stay (11.4 vs. 7.1 days, respectively, [p < .01]) and higher mortality rates within 30 days (0% vs. 5.5%, respectively,[p = .02]). Of culture-negative patients, 28.6% received an alternative diagnosis within one year. Logistic regression models showed that culture positive patients had an adjusted odds ratio for length of stay of 4.5 (2.69, 7.51), intensive care unit admission of 5.76 (1.31, 25.22), discharge to rehabilitation of 4.7 (2.28, 9.71) and an alternative diagnosis within one year of 0.05 (0.02, 0.15) compared to culture negative patients.Conclusion: Patients with culture-negative native joint septic arthritis had less severe disease, better outcomes and higher rates of alternative diagnosis within one year than patients with positive cultures.

Septic arthritis (SA) is typically managed with antibiotic therapy with or without surgery. Little is known about how patients without surgery differ from their operatively managed counterparts. We compared SA patients who received antibiotic treatment with and without surgery. We conducted a retrospective study of patients with monoarticular septic arthritis admitted to a single tertiary care centre between 1998 and 2015. All 441 monoarticular septic arthritis patients received antibiotics; 382 were also managed operatively and 59 nonoperatively. Nonoperative patients were older (64.4 vs 58.3 years old; p = 0.02) and less likely to have prior joint pathology (44.1% vs 67.5%; p < 0.001). Nonoperative patients presented more often with sepsis (37.3% vs 31.9; p = 0.02) and were more frequently admitted to the intensive care unit (23.7% vs 16.5%; p = 0.04). Nonoperative patients were less often discharged to a rehabilitation facility (37.9% vs 55.8%; p = 0.002) and less frequently readmitted to hospital within 60 days of initial discharge (15.3% vs 18.6%; p = 0.05). However, nonoperative patients were more likely to expire within 30 days after hospital discharge (11.9% vs 3.9%; p = 0.009). Nonoperative patients were sicker at presentation; despite deferral of surgery, they had a relatively high survival rate (88%). Among survivors whose data was available, there were no significant sequelae in post-discharge imaging. These findings support the nonsurgical approach as effective for patients with septic arthritis who are not critically ill at time of presentation.

OBJECTIVES: Gout is a common complication of blood pressure management and a frequently cited cause of medication nonadherence. Little trial evidence exists to inform antihypertensive selection with regard to gout risk. METHODS: The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) was a randomized clinical trial on the effects of first-step hypertension therapy with amlodipine, chlorthalidone, or lisinopril on fatal coronary heart disease or nonfatal myocardial infarction (1994-2002). Trial participants were linked to CMS and VA gout claims (ICD9 274.XX). We determined the effect of drug assignment on gout with Cox regression models. We also determined the adjusted association of self-reported atenolol use (ascertained at the 1-month visit for indications other than hypertension) with gout. RESULTS: Claims were linked to 23â964 participants (mean age 69.8â±â6.8 years, 45% women, 31% black). Atenolol use was reported by 928 participants at the 1-month visit. Over a mean follow-up of 4.9 years, we documented 597 gout claims. Amlodipine reduced the risk of gout by 37% (hazard ratio 0.63; 95% CI 0.51--0.78) compared with chlorthalidone and by 26% (hazard ratio 0.74; 95% CI 0.58--0.94) compared with lisinopril. Lisinopril nonsignificantly lowered gout risk compared with chlorthalidone (hazard ratio 0.85; 95% CI 0.70--1.03). Atenolol use was not associated with gout risk (adjusted hazard ratio 1.18; 95% CI 0.78--1.80). Gout risk reduction was primarily observed after 1 year of follow-up. CONCLUSION: Amlodipine lowered long-term gout risk compared with lisinopril or chlorthalidone. This finding may be useful in cases where gout risk is a principal concern among patients being treated for hypertension.This trial is registered at clinicaltrials.gov, number: NCT00000542.

PURPOSE: Patients with septic arthritis (SA) often undergo echocardiographic evaluation to identify concomitant infective endocarditis (IE). The purpose of this study is to identify distinguishing features of patients with SA and IE by comparing them to patients with SA alone. METHODS: We conducted a retrospective study of all patients 18 and older admitted to a single tertiary hospital between 1998 and 2015 with culture-positive SA. Patients were stratified by echocardiogram status and the presence of vegetations: those who had echocardiographic evaluation with no evidence of infective endocarditis (ECHO + IE-) or with a vegetation present (ECHO + IE+) and those who had no echocardiographic evaluation (ECHO-). Demographic data, clinical characteristics, microbiology data, treatment strategies, and patient outcomes were recorded and compared. RESULTS: We identified 513 patients with SA. Transthoracic echocardiogram and/or transesophageal echocardiogram were performed in 263 patients (51.2%) and demonstrated evidence for IE in 19 patients (3.7%). While most demographic features, comorbidities, and clinical characteristics did not differ significantly between those with and without IE, those with IE had higher rates of sepsis and septic shock. In addition, patients with SA and IE had higher rates of positive blood cultures and Methicillin-sensitive staphylococcus aureus (MSSA) infection when compared to those with SA without IE. Patients with IE had higher rates of intensive care unit admission and increased 30-day mortality. CONCLUSIONS: IE is uncommon among patients with SA. Echocardiography may be overutilized and may be more useful among patients presenting with sepsis, shock, or positive blood cultures, especially when MSSA is isolated.

Little is known about the incidence, risk factors, clinical characteristics, and outcomes of patients with polymicrobial SA (PMSA). We aimed to determine the unique characteristics of patients with PMSA by comparing them to patients with monomicrobial SA (MMSA). We conducted a retrospective cohort study of patients 18 years and older admitted to a single tertiary care medical center, between 1998 and 2015, with surgically treated culture-positive SA affecting one or more joints. Patients were separated into two groups by the presence of one (MMSA) or more organisms (PMSA). A total of 441 patients with MMSA and 47 with PMSA were identified. Prior history of SA was more common among the PMSA group (31.9% vs. 18.6%; p = 0.03) as well as higher rates of prosthetic joint involvement (48.9% vs. 36.1%; p = 0.06). Patients with PMSA were sicker with higher rates of shock at presentation (14.9% vs. 5.5%; p = 0.02), intensive care unit admissions (39.1% vs. 18%; p < 0.001), and longer mean length of stay (16.1 vs. 10.9 days; p < 0.001). The most prevalent pathogens in the PMSA group were coagulase-negative Staphylococcus (31%), followed by methicillin-sensitive Staphylococcus aureus (29%), and Enterococcus (24%). To our knowledge, this is the first study to determine the clinical and microbiologic profiles of patients with PMSA. Important differences were noted such as more frequent involvement of atypical and prosthetic joints in PMSA. PMSA should be suspected in patients with these clinical features, and broad-spectrum antibiotics should be considered as these patients appear to be sicker and have worse outcomes.

BACKGROUND: This study aims to test whether persistent pain quality is associated with incident or worsening disability in four domains: mobility, activity of daily living (ADL) and instrumental activity of daily living (IADL) difficulty, and physical performance. METHODS: From the MOBILIZE Boston Study, a population-based cohort of adults aged ≥70 years, we studied participants with chronic pain who endorsed at least one pain quality descriptor (N = 398) and completed baseline and 18-month assessments. Pain quality was assessed using an adapted short-form McGill Pain Questionnaire with 20 pain quality descriptors in three categories: sensory, cognitive/affective, neuropathic. Persistence was defined as endorsing the same category at baseline and 18 months. Self-reported outcomes included mobility, ADL, and IADL difficulty. Physical performance was assessed using the short physical performance battery. RESULTS: After adjusting for baseline pain severity and other covariates, individuals with three persistent categories had a greater risk of developing new or worsening IADL difficulty relative to those with one persistent category (relative risk [RR] 2.69, 95% confidence interval [CI] 1.34, 7.79). Similar results were observed for ADL difficulty (RR 5.83, 95% CI 1.32, 25.85), but no differences were noted in risk for mobility difficulty. There was no significant linear trend in physical performance over 18 months according to number of persistent categories (p =.68). CONCLUSION: Elders with persistent pain quality experienced a higher risk of developing new or worsening IADL and ADL disability with each additional category but not mobility difficulty or poorer physical performance. Longitudinal assessment of pain quality could be useful in determining risk for global disability among elders with chronic pain.

BACKGROUND: Chronic musculoskeletal pain is highly prevalent in the older adults, and individuals with musculoskeletal pain frequently report pain in two or more sites. AIMS: To determine the prevalence and characteristics of multisite pain in relation to other geriatric syndromes and to evaluate whether multisite pain may represent a distinct geriatric syndrome. METHODS: The MOBILIZE Boston Study is a population-based cohort study of older adults that enrolled 749 participants aged 70 and older. Persistent pain in the back and major joint areas was assessed using a joint pain questionnaire. Assessment of other geriatric syndromes included urinary incontinence, fall history, ADL disability, and frailty. A number of risk factors for geriatric syndromes were assessed. RESULTS: The prevalence of multisite pain was 40% in this population of older adults. Many participants had more than one geriatric syndrome, indicating substantial overlap in the prevalence of these conditions. Nearly half (48%) of participants with urinary incontinence or falls, 61% with ADL disability, and 49% of those with frailty also had multisite pain. Shared risk factors for established geriatric conditions were similarly distributed among the elderly population who had multisite pain. Demographic and health characteristics associated with multisite pain and other geriatric syndromes, included gender (female), depression, number of comorbid conditions, and mobility limitations. CONCLUSION: Although prior studies have explored risk factors for chronic multisite pain, these findings reveal that multisite pain, often unexplained, bears many similarities to established geriatric syndromes. Multisite pain warrants further consideration as a unique geriatric syndrome.

Gout is the most common form of inflammatory arthritis. In 2012, the American College of Rheumatology (ACR) issued a guideline, which was followed in 2017 by one from the American College of Physicians (ACP). The guidelines agree on treating acute gout with a corticosteroid, nonsteroidal anti-inflammatory drug, or colchicine and on not initiating long-term urate-lowering therapy (ULT) for most patients after a first gout attack and in those whose attacks are infrequent (<2 per year). However, they differ on treatment of both recurrent gout and problematic gout. The ACR advocates a "treat-to-target" approach, and the ACP did not find enough evidence to support this approach and offered an alternative strategy that bases intensity of ULT on the goal of avoiding recurrent gout attacks ("treat-to-avoid-symptoms") with no monitoring of urate levels. They also disagree on the role of a gout-specific diet. Here, a general internist and a rheumatologist discuss these guidelines; they debate how they would manage an acute attack of gout, if and when to initiate ULT, and the goals for ULT. Lastly, they offer specific advice for a patient who is uncertain about whether to begin this therapy.

Longitudinal assessment of chronic geriatric pain is complicated by an age-associated plateau in pain severity and increase in widespread pain, calling for innovative measures such as pain quality descriptors that characterize how pain may feel. We characterized persistence of pain quality and its relation to severity, activity interference and distribution of sites, in a population-based sample of adults aged≥70 years with chronic pain (n = 398). Persistent pain quality was defined as reporting descriptors within the same category: sensory, cognitive/affective, or neuropathic at baseline and 18 months. A count variable indicated number of persistent categories. Pain quality was highly persistent. Adjusted for baseline covariates, individuals endorsing 3 persistent categories were 2-2.5x more likely to experience more widespread pain at 18 months compared to fewer persistent categories. No associations were noted in changes in pain severity or interference. A comprehensive pain assessment that includes diverse pain quality descriptors may improve individualized pain management.

OBJECTIVES: Septic polyarthritis is rarer than septic monoarthritis, but associated with higher mortality. Septic polyarthritis may be difficult to distinguish clinically from noninfectious inflammatory arthritis. We describe one of the largest samples of septic polyarthritis with the aim of distinguishing septic monoarthritis from polyarthritis. METHODS: We conducted a retrospective study of adults admitted to tertiary care with septic monoarthritis and polyarthritis. Baseline characteristics, microbial profiles, joint involvement, length of stay, and 60-day readmission rates were determined. RESULTS: We identified 464 and 42 cases of septic monoarthritis and polyarthritis, respectively, including 7 cases of septic polyarthritis with comorbid rheumatoid arthritis. Compared to those with septic monoarthritis, patients with septic polyarthritis were more likely to have rheumatoid arthritis (P<0.01), sepsis (P<0.01), and higher peripheral (P<0.001) and synovial (P<0.001) white blood cell counts. Operative intervention rates were similar, but mean length of stay was longer in polyarticular septic arthritis (P<0.001). Patients with septic polyarthritis with/without underlying rheumatoid arthritis were similar in terms of presenting features and outcomes, except for more frequent immunosuppressive therapy in rheumatoid arthritis (P<0.01). CONCLUSIONS: In this sample of patients with septic arthritis, patients with septic polyarthritis were more likely to have systemic infection at presentation than those with septic monoarthritis. Despite this difference, patients with septic monoarthritis and polyarthritis tended to have similar outcomes. While rheumatoid arthritis was observed more frequently among patients with septic polyarthritis, those with/without underlying rheumatoid arthritis had similar presenting features and outcomes.

BACKGROUND: Isolation of bacteria from synovial fluid (SF) is the gold standard for diagnosis of septic arthritis (SA). Contamination results in misdiagnosis and mismanagement. This study identifies clinical characteristics, microbiology, and outcomes of patients with contaminated SF and compares them with patients with true SA. METHODS: We conducted a retrospective study including all patients aged 18 and older admitted to a single, tertiary-care hospital between 1998 and 2015 with suspected SA and positive SF cultures. Contamination cases were determined by infectious disease specialists involved in the patients' care and a clinical course inconsistent with SA. RESULTS: 398 patients with true SA and 22 with contaminated SF were identified. The SA group was younger (60.9 vs. 75.6 years; p < 0.01), had higher peripheral polymorphonuclear lymphocytes (78.0 vs. 69.4%; p < 0.01) and SF white blood cell count (91.7 vs. 25.6K/mL; p = 0.02), and longer mean length of stay (10.9 vs. 6.7 days; p = 0.02). The average time to positive culture was longer in the contaminated group (3.62 vs. 1.4 days; p < 0.01). The SA group was less likely to receive a new rheumatologic diagnosis within 1 year (3.0 vs. 36.4%; p < 0.01). CONCLUSION: This is the first study of its kind looking at clinical features and outcomes of patients with contaminated SF. These patients present with less severe disease, have better outcomes, and receive new rheumatologic diagnoses in more than a third of cases within 1 year. We recommend a conservative approach for patients with suspected contaminated SF, mild symptoms, and no bacterial growth within the first 48 h.
