RESUMO
BACKGROUND: Kidney transplant recipients (KTR) are at risk of severe coronavirus disease 2019 (COVID-19) disease and mortality after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We predicted that hospitalization for COVID-19 and subsequent admission to the intensive care unit (ICU) would yield worse outcomes in KTRs. AIM: To investigate outcomes among KTRs hospitalized at our high-volume transplant center either on the general hospital floor or the ICU. METHODS: We retrospectively describe all adult KTRs who were hospitalized at our center with their first SARS-CoV-2 infection between 04/2020 and 04/2022 and had at least 12 months follow-up (unless they experienced graft failure or death). The cohort was stratified by ICU admission. Outcomes of interest included risk factors for ICU admission and mortality, length of stay (LOS), respiratory symptoms at admission, all-cause graft failure at the last follow-up, and death related to COVID-19. RESULTS: 96 KTRs were hospitalized for SARS-COV-2 infection. 21 (22%) required ICU admission. The ICU group had longer hospital LOS (21.8 vs 8.6 days, P < 0.001) and were more likely to experience graft failure (81% vs 31%, P < 0.001). Of those admitted to the ICU, 76% had death at last-follow up, and 71% had death related to COVID-19. Risk factors for ICU admission included male sex (aHR: 3.11, 95%CI: 1.04-9.34; P = 0.04). Risk factors for all-cause mortality and COVID-19-related mortality included ICU admission and advanced age at SARS-CoV-2 diagnosis. Mortality was highest within a month of COVID-19 diagnosis, with the ICU group having increased risk of all-cause (aHR: 11.2, 95%CI: 5.11-24.5; P < 0.001) and COVID-19-related mortality (aHR: 27.2, 95%CI: 8.69-84.9; P < 0.001). CONCLUSION: ICU admission conferred an increased risk of mortality, graft failure, and longer LOS. One-fifth of those hospitalized died of COVID-19, reflecting the impact of COVID-19-related morbidity and mortality among KTRs.
RESUMO
Purpose: This report describes the clinical and histological characteristics and management of a keratinized lesion of the palpebral conjunctiva in a 59-year-old male. The lesion was identified as a rare acantholytic variant of squamous cell carcinoma that atypically arose from a non-sun exposed region of palpebral conjunctiva. Management was complete excision via Mohs surgery. Observations: A 59-year-old male presented with ocular irritation and chronic foreign body sensation in the right eye. Exam revealed a keratinized lesion in the right lower tarsal conjunctiva, and an initial shave biopsy was non-diagnostic. 12 months later, the patient presented with similar symptoms and a larger, more irregular lesion for which histopathology of a tarsal-involving excisional biopsy was consistent with acantholytic squamous cell carcinoma with involved margins. The patient subsequently underwent complete excision via Mohs surgery and a secondary reconstruction. Conclusions and importance: Acantholytic variants of squamous cell carcinoma are rare and are described as arising from areas with routine sun exposure. This case reports such a lesion arising from non-sun exposed tarsal conjunctiva, as identified by histopathology of a full-thickness excisional biopsy. The lesion was successfully managed with complete excision via Mohs surgery and secondary reconstruction. Given that this histologic variant may be more aggressive and have higher rates of recurrence than other forms of squamous cell carcinoma, this case highlights the importance of complete excisional biopsy and accurate histopathology of concerning periocular lesions and offers a template for management of similar lesions. The unique presenting location should bring awareness to consideration of this type of malignancy developing on palpebral conjunctiva.
RESUMO
Background: Kidney transplant recipients (KTRs) are a vulnerable immunocompromised population at risk of severe COVID-19 disease and mortality after SARS-CoV-2 infection. We sought to characterize the post-infection sequelae in KTRs at our center. Methods: We studied all adult KTRs (with a functioning allograft) who had their first episode of SARS-CoV-2 infection between 04/2020 and 04/2022. Outcomes of interest included risk factors for hospitalization, all-cause mortality, COVID-19-related mortality, and allograft failure. Results: Of 979 KTRs with SARS-CoV-2 infection, 381 (39%) were hospitalized. In the multivariate analysis, risk factors for hospitalization included advanced age/year (HR: 1.03, 95% CI: 1.02-1.04), male sex (HR: 1.29, 95% CI: 1.04-1.60), non-white race (HR: 1.48, 95% CI: 1.17-1.88), and diabetes as a cause of ESKD (HR: 1.77, 95% CI: 1.41-2.21). SARS-CoV-2 Vaccination was associated with decreased risk of hospitalization (HR: 0.73, 95% CI: 0.59-0.90), all-cause mortality (HR: 0.52, 95% CI: 0.37-0.74), and COVID-19-related mortality (HR: 0.47, 95% CI: 0.31-0.71) in the univariate and multivariate analyses. Risk factors for both all-cause and COVID-19-related mortality in the multivariate analyses included advanced age, hospitalization, and respiratory symptoms for hospital admission. Furthermore, additional risk factors for all-cause mortality in the multivariate analysis included being a non-white recipient and diabetes as a cause of ESKD, with being a recipient of a living donor as protective. Conclusions: Hospitalization due to COVID-19-associated symptoms is associated with increased mortality. Vaccination is a protective factor against hospitalization and mortality.
