Background and Objectives: Patients receiving in-center hemodialysis are at a high risk of coronavirus disease 2019 (COVID-19) infection. A reduction in hemodialysis frequency is one of the proposed measures for preventing COVID-19 infection. However, the predictors for determining an unsuccessful reduction in hemodialysis frequency are still lacking. Materials and Methods: This retrospective observational study enrolled patients who were receiving long-term thrice-weekly hemodialysis at the Thammasat University Hospital in 2021 and who decreased their dialysis frequency to twice weekly during the COVID-19 outbreak. The outcomes were to determine the predictors and a prediction model of unsuccessful reduction in dialysis frequency at 4 weeks. Bootstrapping was performed for the purposes of internal validation. Results: Of the 161 patients, 83 patients achieved a dialysis frequency reduction. Further, 33% and 82% of the patients failed to reduce their dialysis frequency at 4 and 8 weeks, respectively. The predictors for unsuccessful reduction were diabetes, congestive heart failure (CHF), pre-dialysis overhydration, set dry weight (DW), DW from bioelectrical impedance analysis, and the mean pre- and post-dialysis body weight. The final model including these predictors demonstrated an AUROC of 0.763 (95% CI 0.654–0.866) for the prediction of an unsuccessful reduction. Conclusions: The prediction score involving diabetes, CHF, pre-dialysis overhydration, DW difference, and net ultrafiltration demonstrated a good performance in predicting an unsuccessful reduction in hemodialysis frequency at 4 weeks.
BackgroundInvasive aspergillosis (IA) has been reported in systemic lupus erythematosus (SLE) patients. We assessed the risk factors of invasive aspergillosis in SLE patients.MethodsA retrospective age- and sex-matched case–control study with ratio 3:1 in adult SLE patients from January 2002- December 2017 at Srinagarind Hospital, Khon Kaen University, KhonKaen, Thailand has been conducted. We excluded the patients who were overlap with other immunocompromised condition.ResultsOf 1,585 SLE patients, 22 patients (1.4%) had invasive aspergillosis and 66 controls were included in the study. The mean age was 36.9 ± 11.8 years and 76 (86.4%) patients were female. SLE patients who developed IA had statistically significant lower median total absolute lymphocyte count than control (503 vs. 1342 cells/mm3, P = 0.05) and history of steroid treatment (adjusted OR 21.43, P = 0.006) were the risk factor of IA.ConclusionThere was a low prevalence of IA in SLE patients. Low total lymphocyte count, renal impairment and history of steroid treatment were significantly associated with invasive aspergillosis in SLE patients.
