Background: Preeclampsia is a unique vascular disease during pregnancy that generally appears after 20 of weeks gestation or until 6 weeks after delivery. Left undiagnosed, preeclampsia can lead rapidly to death of both mother and fetus.

Objectives: To verify the efficacy of peripheral blood inflammatory markers (BIMs)in diagnosing preeclampsia and compare them with results from other studies.

Methods: Our retrospective case-control study comprised two patient groups. Pregnant women with preeclampsia and pregnant women without preeclampsia were compared for BIMs: neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and mean platelet volume (MPV). The primary endpoint of our research was to assess the predictive power of BIMs for preeclampsia diagnosis.

Results: The sample size was calculated based on expected differences of BIMs between the control and study groups. Comparison of quantitative variables was conducted with independent sample t-test or alternatively by Wilcoxon rank sum test. The MPV values were slightly higher in the preeclampsia group, but not statistically significant. NLR and PLR did differentiate between study and control groups.

Conclusions: The diagnostic accuracy of BIMs is unsatisfactory for preeclampsia diagnosis. Discrepancies concerning these values need to be clarified. Further large prospective studies are necessary to validate the potential factor accuracy in preeclampsia diagnosis.

Background: Venous thromboembolism (VTE) is a serious disease, which demands a fast accurate diagnosis to begin suitable treatment. It presents a major problem in the emergency department (ED), and its confirmation requires adequate evaluation.

Objectives: To evaluate a potential role of mean platelet volume (MPV) in differentiating VTE from other potential diagnosis in patients with suspected VTE.

Methods: We conducted a retrospective case-controlled study of 440 consecutive patients who presented to the ED of our hospital with clinical VTE, but only 316 with proven VTE. A control group was composed of patients (124) who presented with clinical VTE but without proven VTE. We checked the MPV value in all 440 patients and the correlation with VTE occurrence in the study group vs. control group.

Results: Statistical analysis of the acquired results indicated that MPV value could not aid in determining the difference of real VTE vs. patients with VTE-like clinical picture presenting to the ED. We found an inverse correlation between MPV value and proven VTE, in contrast to most researchers who have studied the same issue.

Conclusions: Although MPV can be a useful diagnostic marker in many diseases, we found no definite association between low MPV and VTE

Background: The incidence of Clostridium difficile-associated diarrhea (CDAD) is increasing and is associated with significant morbidity and mortality. Therefore, there is a need to find new tools to determine the severity of the disease.

Objectives: To investigate the prognostic values of inflammatory markers such as mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR), and C-reactive protein (CRP) in patients with CDAD.

Methods: The study comprised of 100 patients diagnosed with CDAD. The study included an additional control group of 69 patients with diarrhea who were negative for C. difficile toxin. The control group was age- and sex-matched and hospitalized at the same time period. NLR and MPV were obtained from complete blood count results. Serum CRP levels were measured by the latex particle enhanced immunoturbidimetric assay. Blood samples for all inflammatory markers were collected at time of diagnosis and prior to initiating the antibiotic therapy. Demographic, clinical, laboratory, and prognostic data were collected from medical records for a period of 90 days from the initial diagnosis of CDAD.

Results: The mean age of the CDAD group was 68.6 ± 21.5 years compared to 65.6 ± 24.5 in the control group (P = 0.29). Our findings show that patients with CDAD had significantly higher NLR, MPV and serum CRP levels compared to the control group (P < 0.001)). Moreover, significantly higher levels were observed when CDAD was fatal (P < 0.001).

Conclusions: Elevated NLR, MPV, and serum CRP levels may serve as biomarkers for prediction of recurrence and mortality in patients with CDAD.
