RESUMO
CASE: A 41-year-old woman with recent COVID-19 pneumonia presented to the hospital with several months of fever, polyarthralgia, and weight loss. She reported waxing and waning shoulder, elbow, wrist, hip, knee, and ankle pain without identifiable triggers. She had no pertinent medical or family history. Vital signs were only notable for fever of 40C which recurred daily. Exam revealed tenderness to palpation of multiple joints;her skin had no rash, purpura, or nodules. Hepatosplenomegaly and axillary lymphadenopathy were noted. Infectious workup was negative for bacterial, viral, fungal, mycobacterial, parasitic, and protozoal infections. Initial studies demonstrated hemoglobin 8.2 mg/dL, lymphopenia, and aspartate transaminase 58 U/L. Flow cytometry, excisional lymph node biopsy, and bone marrow biopsy were negative for lymphoproliferative disease. Rheumatologic workup revealed elevated ferritin, triglycerides, Interleukin-6, soluble Interleukin-2 receptor (sIL-2R), and “C-X-C Motif Chemokine Ligand 9” (CXCL9);extensive rheumatologic serologies were otherwise negative. Her clinical picture was consistent with Macrophage Activation Syndrome (MAS). She also met diagnostic criteria for Adult-Onset Still's Disease (AOSD) given arthralgia, fever, lymphadenopathy, splenomegaly, abnormal liver function test (LFT), and otherwise negative workup. Her presentation suggested COVID-19 triggered AOSD which triggered MAS. We administered intravenous immune globulin (IVIG) and high-dose steroids. She clinically improved and was discharged with oral steroids. She returned to the hospital two months later for fever, arthralgia, and faint, evanescent rash with elevated erythrocyte sedimentation rate, C-reactive protein, ferritin, lactate dehydrogenase, and LFT consistent with an AOSD flare. She received intravenous steroids and Anakinra. Symptoms resolved, and she was discharged with plans to continue Anakinra and oral steroids. At followup, she had resolution of all symptoms. IMPACT/DISCUSSION: COVID-19 has many chronic complications, including triggering of underlying rheumatic disease. This sequence of events suggests that COVID-19 Pneumonia triggered an underlying diagnosis of AOSD. AOSD should be considered in the differential diagnosis of patients with quotidian fever and arthralgia following COVID-19 infection. AOSD is a diagnosis of exclusion and requires ruling out infectious, malignant, and rheumatic etiologies. AOSD may trigger MAS, a dysregulated immune response to underlying inflammation, and should be considered in patients with suspected infection refractory to treatment who have fever, splenomegaly, cytopenias, and elevated ferritin, triglycerides, sIL-2R, and CXCL9. CONCLUSION: COVID-19 has many chronic complications. AOSD may manifest after COVID-19 infection and should be considered in the differential diagnosis of patients with persistent fever and arthralgia. MAS should be suspected in patients with systemic inflammation refractory to treatment. AOSD may cause MAS.
RESUMO
In summer 2020, we invited the 6761 undergraduate students who took a Spring 2020 math course at the University of Arizona to participate in a survey, with 13% responding. We asked about their experience with the emergency transition to remote learning and measured their math anxiety before and after the transition using the well-established Abbreviated Math Anxiety Scale (AMAS). "Unmotivated, depressed, anxious" are the words one undergraduate used to describe their emergency transition to remote learning. Our results indicate that limited access to quality technology and inadequate communication with an instructor were the two greatest predictors for an increase in math anxiety after the emergency transition to remote learning. These results may encourage instructors to foster community with their students, especially during emergency remote learning.
