- Original description
This observational study aims to evaluate the diagnostic and prognostic value of the systemic immune-inflammatory index (SII) and the systemic inflammation response index (SIRI) in individuals with overweight or obesity. The study will assess their association with obesity status, metabolic complications, lifestyle patterns, dietary indices, and established inflammatory biomarkers. Participants will undergo anthropometric assessment, laboratory testing, dietary evaluation, and follow-up for response to different obesity treatment modalities over 3 years. The study intends to determine whether SII and SIRI can serve as clinically useful predictors of metabolic risk and treatment outcomes of obesity.Read full original descriptionShow less
Clinical Significance and Prognostic Value of Systemic Immune Inflammation Index and Systemic Inflammation Response Index in Obesity and Associated Metabolic Complications
This observational study aims to evaluate the diagnostic and prognostic value of the systemic immune-inflammatory index (SII) and the systemic inflammation response index (SIRI) in individuals with overweight or obesity. The study will assess their association with obesity status, metabolic complications, lifestyle patterns, dietary indices, and established inflammatory biomarkers. Participants will undergo anthropometric assessment, laboratory testing, dietary evaluation, and follow-up for response to different obesity treatment modalities over 3 years. The study intends to determine whether SII and SIRI can serve as clinically useful predictors of metabolic risk and treatment outcomes of obesity.
Inclusion: Age ≥ 18 years; BMI 25.0-29.9 kg/m² (overweight) or BMI ≥ 30 kg/m² (obesity); Ability to attend scheduled clinical visits; Willingness to provide informed consent.
Exclusion: Use of immunosuppressive therapy; Recent major surgery (within the last 3 months); Active infection; Inflammatory disease; Malignancy; Acute illness affecting immune parameters; Conditions interfering with study participation (as assessed by the investigator); Chronic inflammatory diseases requiring systemic therapy; Any condition that could confound the relationship between SII/SIRI and obesity-driven inflammation, such as immune disorders; Known hematologic disorders affecting leukocyte or platelet counts; Pregnancy or breastfeeding.
