Background: Erysipelas is an acute, recurrent infectious disease caused by Group A β-hemolytic streptococcus. Recurrence occurs in 12–29% of patients, and complications in approximately 31%. International studies indicate that age, sex, and skin conditions are key factors influencing complications and recurrence. In Mongolia, the incidence of erysipelas has not steadily declined, and there is a lack of studies investigating clinical and laboratory predictors of complications and recurrence. Aim:: This study aimed to investigate clinical and laboratory predictors of complications and recurrence among erysipelas cases registered in Mongolia. Materials and Methods: A retrospective cross-sectional study design was employed. A total of 165 patients hospitalized with a diagnosis of erysipelas at the National Center for Communicable Diseases between 2020 and 2024 were randomly selected. Data were collected based on the “Clinical Guidelines for Erysipelas.” Statistical analysis was performed using SPSS-26, and ROC curve analysis along with regression models were used to determine risk and predictive factors. A p-value <0.05 was considered statistically significant. Results: The mean age of participants was 50.4±14.2 years; 76.5% were female, and 32.1% were herders. Recurrence was observed in 55.1% of patients (42.8% repeated episodes, 57.2% recurrent cases), and complications occurred in 10.3%. Among patients with complications, lesions were most commonly located on the face (41.2%) and predominantly presented as erythematous-bullous forms (70.6%). The neutrophil-to-lymphocyte ratio was 7.1 (AUC: 0.85, 95% CI: 0.79–0.91, p=0.001), and the systemic inflammatory response index was 3.9 (AUC: 0.93, 95% CI: 0.88–0.98, p=0.001), indicating high levels. Multivariable regression analysis showed that risk factors for complications included age >45 years (aOR=1.8, 95% CI: 1.2–2.7, p=0.004), female sex (aOR=2.8, 95% CI: 1.7–4.6, p=0.001), and occupation (herder) (aOR=2.6, 95% CI: 1.3–5.4, p=0.001). Chronic tonsillitis was significantly associated with recurrence (OR=3.8, 95% CI: 2.5–5.7, p=0.001). Cox regression analysis demonstrated that each additional year of age increased the risk of complications by 2% (HR=1.02, 95% CI: 1.01–1.03, p=0.003), while the presence of chronic tonsillitis increased the risk of recurrence by 7.69 times (HR=7.69, 95% CI: 5.15–11.49, p=0.001). Conclusion Cellular ratio indicators in erysipelas are useful for assessing inflammatory activity and disease progression. Age, sex, occupation, and the presence of chronic tonsillitis significantly influence the risk of complications and recurrence in erysipelas.

Background: The purpose of this study is to evaluate serum creatinine as a marker of estimated glomerular filtration rate (eGFR) in alcohol use disorder people, and to determine correlation between mean arterial pressure (MAP) and eGFR in chronic kidney disease classification level. Methods: In this study, 118 people were examined 2024. We measured serum creatinine based GFR using the Cockroft Gault formula. Biochemical analysis and serum creatinine were evaluated using a fully automatic analyzer (GOLSITE, China). Statistical results were analyzed SPSS. Result: The mean subject age was 48.6±10.3, BMI 25.3±3.7 and male: female ratio was 5:1. Mean arterial pressure was 104±12.8 mmHg, eGFR 94±28 ml/ min/1.73m2, and mean arterial pressure was significantly correlated with estimated glomerular filtration rate (P<0.05) and no difference between male and female recipients. Mean eGFR was calculated into 4 groups of 10-year intervals, that eGFR was decreased significantly with age groups. For the alcohol dependence stages of the Michigan Test, the mean eGFR was stage 1 is 112 ml/min/1.73m2, stage 2 is 89 ml/min/1.73m2, stage 3 is 97 ml/min/1.73m2 and there is not statistically significant correlation between Michigan test scores and eGFR. Conclusion According to our research, one of the optimal methods for assessing kidney function is the creatinine-based CKD calculation method, and long-term excessive alcohol consumption is a risk factor for CKD, as well as one of the main causes of death due to hypertension and cardiovascular disease.

Methods: In this study, 99 people were examined between January 2024 to November 2024. We measured serum creatinine based GFR using the Cockroft Gault formula. Results were analyzed SPSS. Result: The mean subject age was 48.2±9.9 years, male: female ratio was 5:1. Mean arterial pressure was 103±13.5 mmHg, eGFR 95.5±28.8 ml/min/1.73m2, and mean arterial pressure was significantly correlated with estimated glomerular filtration rate (P<0.05) and no difference between male and female recipients. Conclusion According to our research, one of the optimal methods for assessing kidney function is the creatinine-based CKD calculation method, and excessive alcohol consumption is a risk factor for chronic kidney disease, as well as one of the main causes of complication and mortality in cardiovascular disease.
