RESUMEN

BACKGROUND: The utility of surveillance bronchoscopy (SB) for the clinical management of lung transplant recipients (LTRs) is undefined. This study evaluates the role of SB in the monitoring and care of LTRs. METHODS: We retrospectively analyzed all LTRs who had SB at Henry Ford Hospital in Detroit, Michigan between August 2014 and August 2019. Bronchoscopies performed for clinical symptoms, new radiographic abnormalities, and to assess stents or acute rejection were excluded. A total of 107 LTRs and 449 bronchoscopies were analyzed. The primary outcome was the rate of change in clinical care based on microbiologic and pathologic test results. Secondary outcomes were rates of microbiologic and pathologic test positivity and rates of adverse effects. RESULTS: The most common microbiologic tests performed on bronchoalveolar lavage were bacterial (96.9%), fungal (95.3%), and acid-fast bacillus (95.1%) stains and cultures. Of 2560 microbiologic tests, 22.0% were positive and resulted in therapy changes for 2.9%. Positive galactomannan, acid-fast bacillus tests, and Pneumocystis jirovecii antigen/polymerase chain reaction did not result in therapy changes. Of the 370 transbronchial biopsies performed, 82.2% were negative for acute rejection and 13% were positive for A1/A2 rejection. Immunosuppressive therapy changes occurred after 15.8% with reduction in immunosuppression due to positive microbiologic tests in 16.9%. Adverse events occurred in 8.0% of patients. CONCLUSION: Diagnostic stewardship is warranted when performing SB in LTRs.

RESUMEN

Importance: In late December 2019, an outbreak caused by a novel severe acute respiratory syndrome coronavirus 2 emerged in Wuhan, China. Data on the clinical characteristics and outcomes of infected patients in urban communities in the US are limited. Objectives: To describe the clinical characteristics and outcomes of patients with coronavirus disease 2019 (COVID-19) and to perform a comparative analysis of hospitalized and ambulatory patient populations. Design, Setting, and Participants: This study is a case series of 463 consecutive patients with COVID-19 evaluated at Henry Ford Health System in metropolitan Detroit, Michigan, from March 9 to March 27, 2020. Data analysis was performed from March to April 2020. Exposure: Laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection. Main Outcomes and Measures: Demographic data, underlying comorbidities, clinical presentation, complications, treatment, and outcomes were collected. Results: Of 463 patients with COVID-19 (mean [SD] age, 57.5 [16.8] years), 259 (55.9%) were female, and 334 (72.1%) were African American. Most patients (435 [94.0%]) had at least 1 comorbidity, including hypertension (295 patients [63.7%]), chronic kidney disease (182 patients [39.3%]), and diabetes (178 patients [38.4%]). Common symptoms at presentation were cough (347 patients [74.9%]), fever (315 patients [68.0%]), and dyspnea (282 patients [60.9%]). Three hundred fifty-five patients (76.7%) were hospitalized; 141 (39.7%) required intensive care unit management and 114 (80.8%) of those patients required invasive mechanical ventilation. Male sex (odds ratio [OR], 2.0; 95% CI, 1.3-3.2; P = .001), severe obesity (OR, 2.0; 95% CI, 1.4-3.6; P = .02), and chronic kidney disease (OR, 2.0; 95% CI, 1.3-3.3; P = .006) were independently associated with intensive care unit admission. Patients admitted to the intensive care unit had longer length of stay and higher incidence of respiratory failure and acute respiratory distress syndrome requiring invasive mechanical ventilation, acute kidney injury requiring dialysis, shock, and mortality (57 patients [40.4%] vs 15 patients [7.0%]) compared with patients in the general practice unit. Twenty-nine (11.2%) of those discharged from the hospital were readmitted and, overall, 20.0% died within 30 days. Male sex (OR, 1.8; 95% CI, 1.1-3.1; P = .03) and age older than 60 years (OR, 5.3; 95% CI, 2.9-9.7; P < .001) were significantly associated with mortality, whereas African American race was not (OR, 0.98; 95% CI, 0.54-1.8; P = .86). Conclusions and Relevance: In this review of urban metropolitan patients with COVID-19, most were African American with a high prevalence of comorbid conditions and high rates of hospitalization, intensive care unit admission, complications, and mortality due to COVID-19.
