Can clomiphene citrate resistance be predicted by RDW-CV levels in infertile women with PCOS?

OBJECTIVE

To identify whether red blood cell distribution width coefficient of variation (RDW-CV) and mean platelet volume (MPV) levels can predict clomiphene citrate resistance (CC-R) in infertile, anovulatory females with polycystic ovarian syndrome (PCOS).

METHODS

A total of 89 infertile patients who were admitted to a tertiary center diagnosed with non-obese PCOS were included in this study. The patients were divided into two groups: the first group comprised 53 non-obese patients with PCOS and CC-R, and the second group included 36 non-obese patients with PCOS and CC-S. RDW-CV, RDW-SD, and MPV values, along with routine whole blood count parameters were compared between the groups.

RESULTS

RDW-CV values were found to be significantly higher in the patients with CC-R compared to those with CC-S (P < 0.05). The sensitivity, specificity, positive, and negative predictive values were found to be 69%, 58.1%, 34.5%, and 12.5%, respectively, at an RDW-CV level of 12.85. The odds ratio was calculated as 3.077 (95% CI 1.245-7.603) in terms of the cut-off point.

CONCLUSION

We think that RDW-CV which is a marker of inflammation is a simple, cheap, and accessible marker for the prediction of CC resistance.
