Background Each year, millions face natural disasters, encountering mass fatalities and severe medical issues such as crush injuries and crush syndrome. Crush syndrome, marked by acute kidney injury (AKI) and hyperkalemia, correlates with mortality. This study focuses on presenting epidemiological data on kidney disease resulting from the February 6, 2023 earthquakes centered in Kahramanmaras. Methods This retrospective analysis included patients diagnosed with crush syndrome after the 2023 Kahramanmaras earthquakes, treated in regional hospitals or referred elsewhere in Turkey. Patient data were documented using the web-based system developed by the Turkish Nephrology Association Renal Disaster Working Group. Results Of the 1024 analyzed patients from 46 centers, 515 (50.3%) were women. The mean age was 41 ± 16 years, with a median duration of 12 h under rubble, and the median presentation time to the first health facility was 4 h after extrication from the rubble. Upon admission, 79.8% received intravenous fluid therapy, all potassium-free. Initial serum creatinine, K⁺, and creatinine kinase levels averaged 2.59 ± 2 mg/dl, 5.1 ± 1 mmol/L 38,305 ± 54,303 U/L, respectively. Intensive care unit (ICU) admissions were 53.6%, with mean hospital and ICU stays of 20 and 11 days, respectively. Compartment syndrome occurred in 40.8% of patients, with 75.8% undergoing fasciotomy. Acute kidney injury developed in 67.9% of patients, with 70.3% undergoing hemodialysis, totaling 3016 sessions on 488 patients. The overall in-hospital mortality rate was 9.8%. Conclusion Earthquakes have a significant impact on kidney health. Although our study indicates some progress compared to previous earthquake responses, there remains a crucial need for drills emphasizing post-earthquake initial response, fluid-electrolyte balance management, and emergency dialysis protocols.

Objective: Chronic kidney disease (CKD) is characterized by an irreversible decrease in kidney functions and accumulation of uremic toxins in the body. Platelet indices have the potential to predict the inflammatory status and disease progression in patients with CKD. In this study it was aimed to investigate platelet indices and their relations with renal function and comorbid conditions in CKD patients. Method: In this study it was included 411 CKD patients. We looked for associations between platelet indices and estimated glomerular filtration rate (eGFR). We generated linear regression models for platelet indices that may be associated with eGFR. We evaluated CKD patients for possible associations between platelet indices and comorbid conditions such as diabetes, hypertension, and cardiovascular diseases. Results: The mean age of CKD patients was 60.5 and the GFR value was 40.1+24.8 mL/min/1.73m2. While the mean platelet count, MPV, PCT, PDW, P-LCR values were lower in the advanced CKD group, hematocrit adjusted platelet count (HAPC), MPV/Lymphocyte ratio and SII parameters were higher in the advanced CKD group (p
