For patients with atypical clinical manifestations, the diagnosis of sarcoidosis is difficult and specific biomarkers may play an important role in assisting diagnosis. Previous research has demonstrated a correlation between sarcoidosis and increased carbohydrate antigen 125(CA125), but remains a lack of large cohort studies to validate this observation.AIM To compare serum CA125 levels in sarcoidosis patients and healthy controls, and explore whether CA125 can be used as a biomarker for the diagnosis of sarcoidosis.METHODS In this study, the serum CA125 levels were measured by enzyme-linked immunosorbent assay in 108 consecutive sarcoidosis patients between June 2016 and December 2020(31 males, 77 females;age at diagnosis 49.69 ± 9.10 years) and 112 healthy subjects. Data on the C-reactive protein, erythrocyte sedimentation rate, and angiotensin-converting enzyme were also collected. The association of serum CA125 levels with clinical, radiological, and respiratory functional characteristics was analyzed between patient groups with CA125 ≤ 35 U/mL or CA125 >35 U/mL.RESULTS We found that serum CA125 levels were higher in sarcoidosis patients compared to healthy controls(median: 44.78 vs 19.11 U/mL, P < 0.001). The area under the receiver operator characteristic was 0.9833(95%CI: 0.9717-0.9949), and the best cutoff point was 32.33 U/mL. The elevated serum CA125 was notably associated with the percentage of predicted forced vital capacity(FVC%) and neutrophil-to-lymphocyte ratio(P =0.043 and P = 0.038, respectively) in sarcoidosis patients. Multivariate analysis revealed that FVC%was a statistically notable predictor of elevated serum CA125(P = 0.029). Also, our research revealed that compared to patients with Stage I of radiology classification, patients with Stage Ⅱ and Ⅲ showed a higher concentration of serum CA125(46.16 ± 8.32 vs 41.00 ± 6.04 U/mL, P =0.005, and 47.92 ± 10.10 vs 41.00 ± 6.04 U/mL, P = 0.002, respectively).CONCLUSION Serum CA125 was highly increased in sarcoidosis patients and showed high efficiency for noninvasive diagnosis of the disease. In addition, abnormally elevated serum CA125 was correlated with pulmonary function and radiological Scadding’s classification of sarcoidosis.展开更多
