Raised interleukin-6 levels in obese patients

Area of Science:

• Biochemistry
• Metabolic Syndrome
• Pulmonary Medicine

Background:

• Obesity is linked to biochemical, metabolic, and pulmonary abnormalities.
• Inflammatory mediators like IL-6 may impact glucose and lipid metabolism.
• Hypoxemia can trigger IL-6 release.

Purpose of the Study:

• To investigate serum IL-6 levels in healthy individuals and obese patients.
• To compare IL-6 levels across obese patients without OSAS, with OSAS, and with OHS.
• To explore the relationship between IL-6 and obesity-related respiratory conditions.

Main Methods:

• Serum IL-6 levels were measured.
• Study included 25 obese patients (BMI > 35 kg/m2) and 12 healthy women.
• Obese patients were categorized into groups: without OSAS, with OSAS, and with OHS (baseline SpO2 < 93%).

Main Results:

• Significant differences in IL-6 levels were observed between controls and obese groups.
• Obese patients without OSAS showed higher IL-6 (7.69 pg/mL) than controls (1.28 pg/mL).
• Patients with OHS exhibited the highest IL-6 concentrations (43.13 pg/mL).

Conclusions:

• Serum IL-6 is elevated in obese patients.
• Obesity hypoventilation syndrome is associated with the highest IL-6 levels.
• IL-6 may serve as a biomarker for obesity-related complications.
