HSP does occur in older patients at a much lower frequency. <strong>Objective:</strong> To discuss the atypical presentation of HSP in an elderly adult and the increased nephrogenic risks that are involved in this patient group. <strong>Case Presentation: </strong>We present the history, physical findings, laboratory results, and the clinical course of a 74-year-old Caucasian male with an atypical presentation of HSP. Our patient presented with severe gastrointestinal and cutaneous symptoms which occurred after the onset of abdominal pain. Biopsies demonstrated leukocytoclastic vasculitis in the skin and acute inflammation and hemorrhage in the gastrointestinal tract. The diagnosis was confirmed as IgA vasculitis following the renal biopsy. The patient’s symptoms improved with the administration of methylprednisolone. <strong>Conclusion:</strong> In adults with HSP there is greater concern regarding renal involvement and a greater risk of developing end-stage renal disease compared to children. The importance of recognizing HSP in the elderly is imperative for early diagnosis and appropriate treatment to limit renal damage.展开更多

Several mechanisms were postulated as a cause of AKI in patients infected with COVID-19. The appropriate management of AKI in patients with COVID-19 remains unclear at this time. One point of absolute importance, is the consideration of volume status. Given the paucity of knowledge with regards to the role of different strategies for fluid management during an episode of AKI in patients with COVID-19, this retrospective study aims to compare renal outcome and overall prognosis in patients who received conservative versus liberal fluid management. <strong>Methods:</strong> This is a single-center retrospective observational cohort study at a community hospital in Westchester County, NY. All adult patients who tested positive for the COVID-19 infection by PCR testing of a nasopharyngeal swab and were hospitalized from March 22, 2020 to May 25, 2020 are eligible. Among those identified with AKI, patients were divided into two groups: conservative fluid administration versus liberal fluid administration. <strong>Results:</strong> Of the 136 patients, 84 (61.76%) were admitted to the ICU, with 60% of patients under the conservative fluid strategy and 40% receiving liberal fluid management. On the other hand, 52 (38.23%) patients were admitted on the medical floors, with more patients (67.31%) receiving liberal fluid management. <strong>Discussion:</strong> In our cohort of 136 patients with COVID-19 respiratory illness and AKI, there was a significant difference in renal outcome, in terms of improvement of renal function in patients receiving liberal fluid management (55.07%) versus conservative fluid management (16.41%, p ≤ 0.001), with more patients in the liberal group having lower peak creatinine before levels improved. This, as well, was associated with improvement in oxygenation, characterized by improvement in respiratory status, facilitating weaning of oxygen supplementation (p < 0.001). On the other hand, there was no significant difference between the conservative and liberal groups in terms of undergoing renal replacement therapy. Twenty-one of the 136 patients with AKI required RRT and 19 (90%) of them were admitted to the ICU and mechanically ventilated. On the other hand, there was no statistical difference in mortality rate of patients who underwent renal replacement therapy, regardless of whether they were in the conservative or liberal strategy group. <strong>Conclusion:</strong> Our data report that liberal fluid management in COVID-19 patients with AKI, had better outcomes, in terms of renal function, oxygenation and mortality rate, as compared to patients in the conservative fluid management group. Once patients are started on renal replacement therapy, however, renal and lung outcomes and mortality rate become insignificant between the two groups.展开更多
