Serum Albumin and C3 Complement Levels in Endometriosis

Endometriosis remains a challenging diagnosis due to nonspecific symptoms and limited biomarkers. Prior research has shown that diagnostic accuracy often depends on imaging and surgical confirmation. No prior work had resolved whether serum proteins like albumin or C3 complement could serve as reliable indicators. This gap motivated the current study to explore these markers. Researchers aimed to determine if these proteins could differentiate endometriosis from healthy controls. The study focused on reproductive-age women, a key demographic for early diagnosis. Existing methods lack non-invasive options, prompting interest in serum-based alternatives. This paper's contribution lies in comparing two potential biomarkers for endometriosis detection.

The study aimed to assess whether serum albumin and C3 complement levels could serve as diagnostic tools for endometriosis. Researchers sought to compare these markers between patients and controls. The motivation stemmed from the need for non-invasive, cost-effective diagnostic methods. Endometriosis often requires invasive procedures for confirmation. This paper tested if serum levels of these proteins could provide a simpler alternative. The specific problem addressed was the lack of reliable early biomarkers. The study focused on reproductive-age women to capture relevant diagnostic patterns. The goal was to identify which marker, if any, showed significant differences between groups.

The study employed a cross-sectional design comparing endometriosis patients and controls. Forty-four patients and 44 controls were recruited for the analysis. Serum albumin levels were measured using the Micro Lab 300 device. C3 complement levels were assessed via ELISA. Data were analyzed using SPSS version 21. Groups were compared using statistical tests for mean differences. Patients with comorbid conditions were excluded to ensure accuracy. The study focused on reproductive-age women to maintain consistency.

Serum C3 complement levels were significantly higher in endometriosis patients compared to controls. The mean C3 level was 1120.9±265 μg/ml in controls and 2241.0±293 μg/ml in patients. The p-value for this difference was less than 0.001, indicating statistical significance. Albumin levels showed no significant difference between groups. The mean albumin level was 4.62±0.88 g/dl in controls and 4.42±0.52 g/dl in patients. The p-value for albumin was 0.201, suggesting no meaningful difference. These results suggest C3 complement may be a useful diagnostic marker. Albumin did not demonstrate sufficient discriminatory power.

The authors concluded that serum C3 complement levels were significantly elevated in endometriosis patients. This finding suggests C3 could serve as a potential diagnostic marker. Albumin levels did not show significant differences between groups. The study did not propose C3 as a definitive diagnostic tool. Researchers emphasized the need for further validation in larger cohorts. No essentiality was assigned to either marker beyond the observed differences. The results highlight the importance of exploring multiple serum proteins. Future work may refine the role of C3 in endometriosis diagnostics.
