Simplified Creatinine Index as Predictor of Malnutrition in Stage 5 Chronic Kidney Disease Patients on Maintenance Haemodialysis.

Background: Malnutrition inflammation score (MIS) is an instrument for assessing the nutritional status of stage 5 CKD patients, while simplified creatinine index (SCI) is used to assess muscle mass indirectly. Purpose: This study aims to analyse the correlation between SCI and MIS, as well as determine the SCI cut-off value as a predictor of malnutrition in stage 5 CKD patients on maintenance HD. Methods: This research was an analytical observational study with a cross-sectional study approach. The 132 research subjects were stage 5 CKD patients at the HD Unit of RSUP Dr. Hasan Sadikin Bandung. The research used the Rank-Spearman test with SPSS for correlative bivariate analysis. The area under the curve (AUC) on the receiver operating characteristic (ROC) curve was analysed to find the SCI cut-off value as a predictor of malnutrition in stage 5 CKD patients. Results: Sixty-three subjects (47.7%) were classified as good nutrition and 69 subjects (52.3%) as poor nutrition. The average SCI value in this study was 24.5 mg/kg/day ± SD 3.2 mg/kg/day, with a median MIS value was 6. This study showed a significant negative correlation between SCI and MIS (r = -0.586, p < 0.001). The optimal SCI cut-off from the ROC curve analysis value was ≤ 24.53 mg/kg/day (sensitivity = 76.8%; specificity = 79.4%). Conclusion: A negative correlation existed between SCI and MIS, with an SCI value ≤ 24.53 indicating poor nutritional status in stage 5 CKD patients on maintenance HD. SCI can be used as a predictor of malnutrition at a lower cost and easier.

Challenge in diagnosis of COVID-19 in hemodialysis patient: a case report and brief review of the literature.

Diagnosis of COVID-19 in end-stage kidney disease (ESKD) patients on hemodialysis is challenging,  as the symptoms are often atypical. Herein, we reported a confimed case of COVID-19 in a patient on maintenance hemodialysis. A 38-year-old man with ESKD on regular hemodialysis initially presented with progressive shortness of breath and dry cough, without fever. He had lymphopenia, and chest X-ray suggested pulmonary edema with cardiomegaly and suspected bilateral bronchopneumonia. The patient clinically improved after 7 days of hospitalization, and was subsequently discharged from hospital. Ten days after being discharged, the patient was re-admitted with progressive shortness of breath and dry cough, without fever. SARS-CoV-2 infection was later confirmed by a qualitative RT-PCR test and the diagnosis COVID-19 pneumonia was established. We presented a case of atypical presentation of COVID-19 in an ESKD patient on maintenance hemodialysis with a brief review of the current literature.
