Introduction
The aim of the study was to assess the etiological distribution of patients with an erythrocyte sedimentation rate (ESR) over 100 mm/hour and to evaluate differences in demographic, comorbidity, laboratory characteristics, and clinical outcomes.
Methods
This retrospective observational clinical study included patients aged 18 years and older who were admitted to the internal medicine inpatient clinic between May 1, 2015 and June 1, 2021 and had ESR values above 100 mm/h. Demographic data, comorbidities, laboratory parameters, imaging studies, histopathological findings, microbiological and serological data, along with in-hospital and post-discharge mortality, were collected from the hospital’s electronic database. Two independent clinicians evaluated the data to identify diagnoses associated with elevated ESR. Patients were divided into six categories based on the most likely diagnosis.
Results
The study included 441 patients, 52.6% of whom were female, and the mean age was 72.6 years. The etiological distribution was as follows: infectious diseases (34%), malignancies (31.5%), undiagnosed cases (15.9%), renal diseases (9.8%), other causes (5%), and rheumatologic diseases (3.8%). Etiological distributions did not differ by gender, age, or ESR ranges. The in-hospital mortality rate was 3.6%, and the overall mortality rate from hospitalization to the data collection date was 64.4%. Mortality was higher in patients with malignancies (81.3%) compared to other etiologies (p<0.001). Patients who died had higher mean age, ferritin levels, having diabetes mellitus, heart failure, or malignancy, and lower hemoglobin and lymphocyte levels compared to survivors (p<0.05 for all).
Conclusion
Most patients with an ESR over 100 mm/hour had significant underlying medical conditions, with infectious diseases and malignancies comprising two-thirds of the cases.
