Postdischarge thromboembolic outcomes and mortality of hospitalized patients with COVID-19: the CORE-19 registry.

Thromboembolic events, including venous thromboembolism (VTE) and arterial thromboembolism (ATE), and mortality from subclinical thrombotic events occur frequently in coronavirus disease 2019 (COVID-19) inpatients. Whether the risk extends postdischarge has been controversial. Our prospective registry included consecutive patients with COVID-19 hospitalized within our multihospital system from 1 March to 31 May 2020. We captured demographics, comorbidities, laboratory parameters, medications, postdischarge thromboprophylaxis, and 90-day outcomes. Data from electronic health records, health informatics exchange, radiology database, and telephonic follow-up were merged. Primary outcome was a composite of adjudicated VTE, ATE, and all-cause mortality (ACM). Principal safety outcome was major bleeding (MB). Among 4906 patients (53.7% male), mean age was 61.7 years. Comorbidities included hypertension (38.6%), diabetes (25.1%), obesity (18.9%), and cancer history (13.1%). Postdischarge thromboprophylaxis was prescribed in 13.2%. VTE rate was 1.55%; ATE, 1.71%; ΑCM, 4.83%; and MB, 1.73%. Composite primary outcome rate was 7.13% and significantly associated with advanced age (odds ratio [OR], 3.66; 95% CI, 2.84-4.71), prior VTE (OR, 2.99; 95% CI, 2.00-4.47), intensive care unit (ICU) stay (OR, 2.22; 95% CI, 1.78-2.93), chronic kidney disease (CKD; OR, 2.10; 95% CI, 1.47-3.0), peripheral arterial disease (OR, 2.04; 95% CI, 1.10-3.80), carotid occlusive disease (OR, 2.02; 95% CI, 1.30-3.14), IMPROVE-DD VTE score ≥4 (OR, 1.51; 95% CI, 1.06-2.14), and coronary artery disease (OR, 1.50; 95% CI, 1.04-2.17). Postdischarge anticoagulation was significantly associated with reduction in primary outcome (OR, 0.54; 95% CI, 0.47-0.81). Postdischarge VTE, ATE, and ACM occurred frequently after COVID-19 hospitalization. Advanced age, cardiovascular risk factors, CKD, IMPROVE-DD VTE score ≥4, and ICU stay increased risk. Postdischarge anticoagulation reduced risk by 46%.

IgG4-Related Sclerosing Disease of the Breast in a Male Patient.

IgG4-related sclerosing disease of the breast is a rare entity with 10 reports in the literature. We report the first case in a male patient. A 48-year-old male presented with 4-week history of palpable right upper outer quadrant breast mass associated with skin puckering. He reported a family history of breast cancer in his aunt. Ultrasound and mammography showed a spiculated 2.5-cm mass associated with skin retraction with extension to the pectoralis muscle. Ultrasound-guided core biopsy was performed. The findings were interpreted as acute and chronic inflammatory process. The patient subsequently denied improvement of the mass, and an excisional biopsy was performed. Histologic examination showed fibrosis and dense lymphoplasmacytic inflammation in the breast mass and muscle biopsy. Focal obliterative phlebitis was noted. IgG4-positive plasma cells were increased with counts of over 50 per high-power field. The diagnosis was confirmed as sclerosing IgG4-related disease of breast.

Severe upper airway obstruction from cricoarytenoiditis as the sole presenting manifestation of a systemic lupus erythematosus flare.

Upper airway obstruction due to laryngeal involvement is a known complication of systemic lupus erythematosus (SLE). Laryngeal involvement typically accompanies inflammatory activity involving other sites and varies from mild mucosal inflammation to bilateral vocal cord immobility. Cricoarytenoid arthropathy is a rare cause of severe airway obstruction in patients with SLE and almost always occurs in the presence of other associated symptoms. Furthermore, in contrast to patients with rheumatoid arthritis, in whom chronic involvement of cricoarytenoid joints occurs more commonly and often requires surgical intervention, patients with SLE typically present with acute arthritis of cricoarytenoid joints and respond to corticosteroid therapy alone. We describe a patient with known SLE who presented with severe acute upper airway obstruction as the sole manifestation of active SLE after several years of quiescence. The laryngeal involvement progressed from mucosal inflammation to acute cricoarytenoiditis, despite the administration of high-dose corticosteroid therapy, necessitating emergent intubation and tracheostomy. This case illustrates the importance of considering SLE in the differential diagnosis of patients presenting with acute upper airway obstruction.
