Neutrophil/lymphocyte ratio and mean platelet volume in Behçet's disease.

OBJECTIVE

With this retrospective study, we researched the effects of mean platelet volume (MPV) and neutrophil/lymphocyte ratio (NLR) on the activity of Behçet's disease and susceptibility to thrombosis.

PATIENTS AND METHODS

One hundred eighty-six patients with Behçet's disease, who met the inclusion criteria, were separated into two groups: 120 patients had active Behçet's disease (Group I) and 66 patients with inactive Behçet's disease (Group II). 79 healthy subjects as controls were included in the study.

RESULTS

MPV was similar between all three groups. CRP (C reactive protein) was statistically higher in the active BD group when compared to the inactive BD group and the control group. CRP of the inactive BD and the healthy control group were similar. In addition, erythrocyte sedimentation rate (ESR) was found higher than the control group in both active and inactive BD groups, whereas ESR of the active BD group was higher than the inactive BD group. N/L ratio was found statistically higher in the active BD group when compared to inactive BD and healthy control groups, while the N/L ratio of inactive BD and healthy control groups were found similar to each other. While MPV, CRP, and NLR didn't statistically differ between active BD subgroups with and without thrombosis, ESR was statistically and significantly higher in the active BD group with thrombosis when compared to the active BD group without thrombosis.

CONCLUSIONS

The data obtained from the present study showed that the patients with BD are exposed to chronic inflammation. And the N/L ratio may be a simple, inexpensive, and convenient diagnostic marker of active BD.
