<b><i>Introduction:</i></b> Kidney involvement, ranging from mild hematuria and proteinuria to acute kidney injury (AKI) in patients with coronavirus disease-2019 (COVID-19), is a recent finding with various incidence rates reported among hospitalized patients with COVID-19. Given the various AKI rates and their associated risk factors, lack of AKI recovery in the majority of patients hospitalized with COVID-19, and limited data regarding AKI in patients with COVID-19 in Iran, we aim to investigate the potential risk factors for AKI development and its incidence in patients hospitalized with COVID-19. <b><i>Methods:</i></b> In this retrospective cohort study, we enrolled adult patients referred to the Sina Hospital, Iran, from February 20 to May 14, 2020, with either a positive PCR test or a highly susceptible chest computed tomography features consistent with COVID-19 diagnosis. AKI was defined according to the kidney disease improving global outcomes criteria, and patients were stratified based on their AKI staging. We evaluated the risk indicators associated with AKI during hospitalization besides in-hospital outcomes and recovery rate at the time of discharge. <b><i>Results:</i></b> We evaluated 516 patients with a mean age of 57.6 ± 16.1 years and a male-to-female ratio of 1.69 who were admitted with the COVID-19 diagnosis. AKI development was observed among 194 (37.6%) patients, comprising 61.9% patients in stage 1, 18.0% in stage 2, and 20.1% in stage 3. Out of all patients, AKI occurred in 58 (11.2%) patients during the hospital course, and 136 (26.3%) patients arrived with AKI upon admission. AKI development was positively associated with all of the in-hospital outcomes, including intensive care unit admissions, need for invasive ventilation, acute respiratory distress syndrome (ARDS), acute cardiac injury, acute liver injury, multiorgan damage, and mortality. Patients with stage 3 AKI showed a significantly higher mortality rate, ARDS, and need for invasive ventilation than other stages. After multivariable analysis, male sex (odds ratio [OR]: 11.27), chronic kidney disease (CKD) (OR: 6.89), history of hypertension (OR: 1.69), disease severity (OR: 2.27), and high urea levels (OR: 1.04) on admission were independent risk indicators of AKI development. Among 117 (28.1%) patients who experienced AKI and survived, only 33 (28.2%) patients made a recovery from the AKI, and 84 (71.8%) patients did not exhibit full recovery at the time of discharge. <b><i>Discussion/Conclusion:</i></b> We found that male sex, history of CKD, hypertension, disease severity, and high serum urea were independent risk factors associated with AKI in patients with COVID-19. Also, higher stages of AKI were associated with increased risk of mortality and in-hospital complications. Our results indicate a necessity for more precise care and monitoring for AKI during hospitalization in patients with COVID-19, and lack of AKI recovery at the time of discharge is a common complication in such patients.
Background: Esophageal stent insertion in patients with inoperable esophageal cancer is usually accompanied with relatively high adverse symptoms and even mortality. The current study aims at investigating the outcomes of esophageal stenting in patients with inoperable non-cervical esophageal cancer.Materials and Methods: The current descriptive-analytical research evaluates 25 patients with esophageal cancer. The stent was placed in esophagus based upon endoscopy analysis with or without fluoroscopy and then the stent position and its opening was investigated by making use of CXRand Gastrografin studies. Demographic characteristics, dysphagia scores, stent placement side effects and the dysphagia-related indices were recorded and examined by taking advantage of a questionnaire which was administered pre and post stent insertion.Results: The study population was comprised of 15 women and 10 men. The individuals' average age was 69.20 ± 11.25 years. Dysphagia mean score was lowered from a value of 4.32 ± 0.80 to 2.00 ± 1.22 (P-value<0.05). The prevalent side effects were chest pain (64%), dysphagia recurrence (40%), stent blockage (20%), stent migration (16%), GI bleeding (8%), and malposition (8%). Also, it was found out that 64% of the patients survived for 6 months.Conclusion: The results indicated that although esophageal stenting is accompanied with side effects in patients with inoperable esophageal cancer, but it is the most frequently used and the most reliable method in relieving dysphagia and improving dysphagia-related life indices.
The novel coronavirus disease 2019 (COVID-19) is a respiratory infection that has received much attention due to its rapid expansion. Currently, it has been revealed that patients with underlying disease, especially those with kidney disease are more prone to develop complications. Some studies associate kidney transplantation as a risk factor for COVID-19 progression; however, epidemiologic data that demonstrate this are amazingly rare. Considering the importance of the topic, we report on six kidney transplant recipients (median age 47 [41-55]) with confirmed or clinically suspected COVID-19. The most common admission presentations were fever (83.3%), dyspnea, and myalgia. At baseline, immunosuppressive therapy was ceased, prednisolone dose was increased, and all patients received antiviral treatment including hydroxychloroquine and umifenovir. After a median follow-up of 11.5 days from admission, six patients (100%) developed acute kidney injury (AKI), 50% required intensive care unit (ICU) admission, and two patients (33.3%) deceased as a result of deterioration in respiratory status. Overall, these findings demonstrate that respiratory involvement may be a risk indicator of in-hospital mortality in kidney recipients with COVID-19. In addition, AKI development in kidney recipients with COVID-19 is of utmost importance given the higher AKI occurrence in these patients compared with others. Therefore, more intensive attention should be paid to kidney transplant recipients with COVID-19.
