RESUMO

We report the nationwide experience with solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients diagnosed with coronavirus disease 2019 (COVID-19) in Spain until 13 July 2020. We compiled information for 778 (423 kidney, 113 HSCT, 110 liver, 69 heart, 54 lung, 8 pancreas, 1 multivisceral) recipients. Median age at diagnosis was 61 years (interquartile range [IQR]: 52-70), and 66% were male. The incidence of COVID-19 in SOT recipients was two-fold higher compared to the Spanish general population. The median interval from transplantation was 59 months (IQR: 18-131). Infection was hospital-acquired in 13% of cases. No donor-derived COVID-19 was suspected. Most patients (89%) were admitted to the hospital. Therapies included hydroxychloroquine (84%), azithromycin (53%), protease inhibitors (37%), and interferon-ß (5%), whereas immunomodulation was based on corticosteroids (41%) and tocilizumab (21%). Adjustment of immunosuppression was performed in 85% of patients. At the time of analysis, complete follow-up was available from 652 patients. Acute respiratory distress syndrome occurred in 35% of patients. Ultimately, 174 (27%) patients died. In univariate analysis, risk factors for death were lung transplantation (odds ratio [OR]: 2.5; 95% CI: 1.4-4.6), age >60 years (OR: 3.7; 95% CI: 2.5-5.5), and hospital-acquired COVID-19 (OR: 3.0; 95% CI: 1.9-4.9).

RESUMO

BACKGROUND: Few studies have analyzed differences in clinical presentation and outcomes in solid organ transplant (SOT) recipients with coronavirus disease 2019 (COVID-19) across different pandemic waves. METHODS: In this multicenter, nationwide, prospective study, we compared demographics and clinical features, therapeutic management, and outcomes in SOT recipients diagnosed with COVID-19 in Spain before (first wave) or after (second wave) 13 July 2020. RESULTS: Of 1634 SOT recipients, 690 (42.2%) and 944 (57.8%) were diagnosed during the first and second periods, respectively. Compared with the first wave, recipients in the second were younger (median: 63 y [interquartile range, IQR: 53-71] versus 59 y [IQR: 49-68]; P < 0.001) and less likely to receive anti-severe acute respiratory syndrome coronavirus 2 drugs (81.8% versus 8.1%; P < 0.001), with no differences in immunomodulatory therapies (46.8% versus 47.0%; P = 0.931). Adjustment of immunosuppression was less common during the second period (76.4% versus 53.6%; P < 0.001). Hospital admission (86.7% versus 58.1%; P < 0.001), occurrence of acute respiratory distress syndrome (34.1% versus 21.0%; P < 0.001), and case-fatality rate (25.8% versus 16.7%; P < 0.001) were lower in the second period. In multivariate analysis, acquiring COVID-19 during the first wave was associated with an increased risk of death (OR: 1.47; 95% confidence interval [CI], 1.12-1.93; P = 0.005), although this impact was lost in the subgroup of patients requiring hospital (OR: 0.97; 95% CI, 0.73-1.29; P = 0.873) or intensive care unit admission (OR: 0.65; 95% CI, 0.35-1.18; P = 0.157). CONCLUSIONS: We observed meaningful changes in demographics, therapeutic approaches, level of care, and outcomes between the first and second pandemic waves. However, outcomes have not improved in the more severe cases of posttransplant COVID-19.
