Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has undergone various mutations of Corona Virus Disease 2019 (COVID-19). The World Health Organization (WHO) has designated B.1.617.2 (Delta) and B.1.1.529 (Omicron) as variants of concern (VOC). Since clinical features and epidemiological characteristics of patients infected with SARS-CoV-2 variants remain largely unknown, especially in Indonesia, this study aimed to identify the clinical characteristics of COVID-19 patients from South Kalimantan, Indonesia. Methods: Data from medical records of COVID-19 patients at Ulin General Hospital Banjarmasin from June 2021 to February 2022 were randomly extracted, containing demographic data, comorbidities, and laboratory data, as well as the type of virus. Results: In total, 32 patients were included, 9 were infected with delta, 14 with probable omicrons, and 9 with non-VOC. Patients in the probable Omicron group were significantly older than other groups (median age 64 years old, range 54–73 years; p=0.049), had hypertension as the dominant comorbidity (85.7%; p=0.039), the onset appeared slightly earlier (median 3 days; range 2-3 days, p=0.062), with no anosmia symptom (p=0.006). Critical illness predominated and mostly survived in all variants but was not statistically significant (p=0.590 and 0.726, respectively). The three variants showed similarities in laboratory findings; hence, statistical analysis suggested that the leucocytes differed significantly (p=0.020). Conclusions: Patients with the likely Omicron variant are much older, have hypertension as their main comorbidity, do not have any symptoms of anosmia, and have higher leukocyte counts compared to other variants.

Corona Virus Disease (COVID-19) is becoming a global pandemic. Indonesia, especially South Kalimantan had recorded increasing cases with a high fatality rate of 3.7%. Information about factors related to outcomesbased on clinical and laboratory features in Indonesia is still limited. Identification of the risk is crucial to determine optimal management and reducing mortality. This retrospective study enrolled 455 adults COVID-19 patients and data were extracted from med-ical records of Ulin General Hospital Banjarmasin.The latter is COVID-19 refer-ral hospital in South Kalimantan between March-November 2020. Demographic data, comorbidities,and laboratory were all collected. Data were compared be-tween survivors and non-survivors. Fisher’s exact test and chi-square wereused to compare categorical variables. The Mann-Whitney U test was used to compare continuous variables. Analysis was continued by multivariate logistic regression then receiver operating characteristic (ROC) curve to determine cut-off value. The multivariate analysis showed that number of comorbidities [odds ratio (OR) 1,339 (95% confidence interval (CI): 1,064-1,685, P = 0,013) was significant risk factor to the outcome. In laboratory, lactate dehydrogenase (LDH) [OR: 1.001, 95% CI: 1,000-1.002, P = 0.001], Ferritin (OR 1.000, CI: 1,000-1.001, P = 0.013), APTT (OR: 1.045, CI: 1.010-1.082, P = 0.012), and D-dimer (OR: 1.188, CI: 1.064 -1.327, P = 0.002) were significant predictor factors but only LDH, ferritin and D-dimer were obtained good AUC 0.731, 0.715, and 0.705, respectively. The cut of the value of LDH was 656.5 U/L, ferritin was 672.18 ng/ml, and D-dimer was 2.28 mg/L. Sensitivity and specificity were 66.7% and 68,0% for LDH, 83,2% and 56,3% for ferritin, and 62,8 and 70,8% for D-dimer. From this research,we re-vealed that the number of comorbidities was a risk factor for death. Elevated LDH, ferritin, and D-dimer could be good predictive factors for poor outcomes, thereby considering theaccelerating management of COVID-19 patients

Background: Corona Virus Disease (COVID-19) has become a global pandemic and has spread to more than 200 countries including Indonesia. South Kalimantan is one of the provinces in Indonesia that has a high COVID-19 mortality rate (case fatality rate 4.1%). Information about characteristic of mortality patients with SARS-CoV-2 infection in Indonesia was limited. The objective of this study to describe clinical characteristics of COVID-19-confirmed deaths at Ulin Regional Hospital Banjarmasin, as a referral hospital in South Kalimantan Methods: Medical records of 108 hospitalized patients dying with COVID-19 between March until August 2020 were collected. The recorded information included gender, age, onset and severity of disease, comorbidities, symptoms, signs, and laboratory findings Results: The 108 confirmed cases of COVID-19 deaths were mostly male (73.1%) aged
