RESUMO
Leukocytoclastic vasculitis is a histopathologic term describing a type of small-vessel vasculitis characterized by a predominantly neutrophilic inflammatory infiltrate and nuclear debris. Skin involvement is common and can have a heterogeneous clinical presentation. Herein, we describe a 76-year-old woman with no history of chemotherapy or recent mushroom ingestion that presented with focal areas of flagellate purpura secondary to bacteremia. Histopathology revealed leukocytoclastic vasculitis and her rash resolved after antibiotic treatment. It is important to distinguish flagellate purpura from a similar condition, flagellate erythema, as they have been reported in association with distinct etiological and histopathological features.

OBJECTIVE: With hydroxychloroquine (HCQ) and chloroquine (CQ) emerging as potential therapies for coronavirus disease 2019 (COVID-19), shortages have been reported. We aimed to understand how rheumatologists, one of the most common prescribers of HCQ/CQ, prescribed these medications to manage COVID-19 and to understand if their patients are affected by shortages. METHODS: Between April 8 and April 27, 2020, an online survey was distributed to a convenience sample of rheumatologists who practice medicine in a diverse range of settings globally, resulting in 506 responses. Adjusted Poisson regression models were calculated. RESULTS: Only 6% of respondents prescribed HCQ/CQ for COVID-19 prophylaxis, and only 12% for outpatient treatment of COVID-19. Compared to the United States, the likelihood of prescribing HCQ/CQ for prophylaxis was higher in India (adjusted risk ratio [aRR], 6.7; 95% confidence interval [CI], 2.7-16.8; p < 0.001). Further, compared to the United States and those with 1 to 5 years of experience, rheumatologists in Europe (aRR, 2.9; 95% CI, 1.6-5.3; p < 0.001) and those with 10+ years of experience (11-20 years: aRR, 2.5; 95% CI, 1.2-5.3; p = 0.015; 21+ years: aRR = 3.3; 95% CI, 1.4-7.4; p = 0.004) had a higher likelihood of prescribing HCQ/CQ for outpatient treatment. Of note, 71% of all rheumatologists reported that their patients were directly affected by HCQ/CQ shortages. CONCLUSION: The results suggest that only a small percentage of rheumatologists are prescribing HCQ/CQ for prophylaxis or outpatient treatment of COVID-19. Medication shortages experienced by large numbers of autoimmune disease patients are concerning and should play a role in decisions, especially given poor efficacy data for HCQ/CQ in COVID-19.

Background: Patients with inflammatory arthritis are at increased risk of prosthetic joint infections (PJIs), but diagnosis in these patients can be challenging because active inflammatory arthritis produces elevated inflammatory markers that may mimic those seen in PJI. Purpose: In this pilot study, we sought to identify the clinical, microbiologic, and histopathologic features of culture-positive and culture-negative PJI in patients with inflammatory arthritis who underwent total hip arthroplasty (THA) or total knee arthroplasty (TKA). We also sought to obtain preliminary data to support a definitive study of optimal methods for PJI diagnosis in patients with inflammatory arthritis. Methods: We performed a retrospective analysis of TKA and THA patients treated for PJI from 2009 to 2018 at a single tertiary care orthopedic institution. Data were extracted from a longitudinally maintained hospital infection database. We reviewed hematoxylin and eosin slides of osteoarthritis and inflammatory arthritis PJI cases matched 3:1, respectively, by age, sex, and culture status. Clinical characteristics were evaluated using the Fisher exact test, χ2 test, Student t test, and Mann-Whitney U test where appropriate. Results: A total of 807 PJI cases were identified (36 inflammatory arthritis and 771 osteoarthritis cases). Patients with inflammatory arthritis presented younger, had a higher Charlson Comorbidity Index, more frequently used glucocorticoids, were more likely women, and had a higher proportion of culture-negative PJI compared with osteoarthritis patients. Of the 88 inflammatory arthritis cases reviewed for histopathology, a higher proportion of culture-positive than culture-negative PJI cases had >10 polymorphonuclear leucocytes per high-power field and met Musculoskeletal Infection Society criteria but presented with less chronic inflammation. Conclusions: This retrospective prognostic study suggests that culture-negative PJI may be more frequent in patients with inflammatory arthritis than in those with osteoarthritis. Chronic infections, antibiotic use, or misdiagnosis may be contributing factors to unclear PJI diagnoses among culture-negative cases. This preliminary work supports the need for further studies to assess the differences in clinical features between culture-negative and culture-positive PJI in patients with inflammatory arthritis and the ability of biological diagnostic markers to discriminate between them in this population.
RESUMO
OBJECTIVE: To investigate the perceptions and behaviors of rheumatologists in the United States (US) regarding the risk of COVID-19 for their autoimmune patients and the subsequent management of immunosuppressive and anti-inflammatory medications. METHODS: We administered an online survey to a convenience sample of rheumatologists in the US from 4/8/20-5/4/20 via social media and group emails. Survey respondents provided demographic information such as, age, gender, state of practice, and practice type. We asked questions about COVID-19 risk in rheumatic patients, as well as their medication management during the pandemic. We conducted descriptive analysis and Multivariable regression models. RESULTS: 271 respondents completed the survey nationally. 48% of respondents either agreed or strongly agreed with the statement "Patients with rheumatic diseases are at a higher risk of COVID-19 irrespective of their immunosuppressive medications". 50% disagreed or strongly disagreed with the statement "The pandemic has led you to reduce the use/dosage/frequency of biologics", while 56% agreed or strongly agreed with the statement "The pandemic has led you to reduce the use/dosage/frequency of steroids". A third of respondents indicated that at least 10% of their patients had self-discontinued or reduced at least one immunosuppressive medication to mitigate their risk of COVID-19. Responses to these questions as well as to questions regarding NSAID prescription patterns were significantly different in the Northeast region of US compared to other regions. CONCLUSION: In this national sample of rheumatologists, there are variations regarding perceptions of patients' risk of COVID-19, and how to manage medications such as NSAIDs, biologics and steroids during the pandemic. These variations are more pronounced in geographical areas where COVID-19 disease burden was high.

OBJECTIVE: There is emerging evidence that COVID-19 disproportionately affects people from racial/ethnic minority and low socioeconomic status (SES) groups. Many physicians across the globe are changing practice patterns in response to the COVID-19 pandemic. We sought to examine the practice changes among rheumatologists and what they perceive the impact to be on their most vulnerable patients. METHODS: We administered an online survey to a convenience sample of rheumatologists worldwide during the initial height of the pandemic (between 8 April and 4 May 2020) via social media and group emails. We surveyed rheumatologists about their opinions regarding patients from low SES and racial/ethnic minority groups in the context of the COVID-19 pandemic. Mainly, what their specific concerns were, including the challenges of medication access; and about specific social factors (health literacy, poverty, food insecurity, access to telehealth video) that may be complicating the management of rheumatologic conditions during this time. RESULTS: 548 rheumatologists responded from 64 countries and shared concerns of food insecurity, low health literacy, poverty and factors that preclude social distancing such as working and dense housing conditions among their patients. Although 82% of rheumatologists had switched to telehealth video, 17% of respondents estimated that about a quarter of their patients did not have access to telehealth video, especially those from below the poverty line. The majority of respondents believed these vulnerable patients, from racial/ethnic minorities and from low SES groups, would do worse, in terms of morbidity and mortality, during the pandemic. CONCLUSION: In this sample of rheumatologists from 64 countries, there is a clear shift in practice to telehealth video consultations and widespread concern for socially and economically vulnerable patients with rheumatic disease.
