Objective: Behçet's Disease (BD) is a polygenic and chronic autoinflammatory multisystemic vasculitis disease characterised by mucocutaneous, musculoskeletal, neurological, gastrointestinal and ophthalmologic lesions. There has been no specific test or serum marker to measure and determine the diagnosis and severity of BD. Purpose:The study aimed to investigate the diagnostic performance of haematological parameters as MLR (monocyte to lymphocyte ratio), NLR (neutrophil to lymphocyte ratio), PLR (platelet to lymphocyte ratio), MPV (mean platelet volume), MPVPR (mean platelet volume to platelet ratio), LMR (lymphocyte to monocyte ratio), LPM (lymphocyte and platelet multiplication), WLP (lymphocyte and leukocyte multiplication), RDW (red blood cell distribution width) and PCT (plateletcrit) in BD and compare these with disease activity and clinical findings.Methods: A total of 266 participants (49 healthy control and 217 BD patients) were recruited from the rheumatology department in a single-centre as a case-control study. The laboratory data were obtained from the electronic registration database.BD Activity scores (BDCAF/Behcet's Disease Current Activity Form) were calculated. Laboratory findings of BD patients and healthy controls were compared and evaluated.Results: RDW, Platelet, PCT, NLR and PLR values were significantly higher in patient group than in the healthy controls. However, haemoglobin, MPVPR and LMR were significantly lower in the patient group which compared with the healthy controls.LPM in BD with genital ulcers, WLP in BD with genital ulcers and arthritis, MPR in BD with uveitis, RDW in BD with thrombosis and neuro-Behçet's disease (NBD), PLR in NBD were observed to be higher. However, LMR in NBD and MPV in BD with thrombosis were lower than those without. There was a positive correlation between BDCAF score and RDW, and NLR.
Objectives Vitamin D is one of the major hormones involved in the metabolism of calcium (Ca) and phosphorus (P). In the present study, we aimed to determine the analytical performance of the immunoassay method used for determining plasma 25-hydroxyvitamin D [25(OH)D] levels in routine clinical practice in laboratories. Methods Venous blood samples were collected from 156 patients for the comparisons and were analyzed with Siemens ADVIA Centaur XPT, the Roche Cobas 6,000’s module e601, Abbott Architect i2000, and the liquid chromatography with tandem mass spectrometry (LC-MS/MS). Results The four methods were analyzed and compared through the Passing-Bablok regression for 25(OH)D, and the highest correlation was found at LC-MS/MS and Cobas 6,000’s module e601 (r=0.799), LC-MS/MS/Abbott Architect i2000, and LC-MS/MS/Siemens ADVIA Centaur XPT as r=0.736, 0.721, respectively. The correlation coefficient was found between Abbott Architect i2000 with Roche Cobas e601 and Siemens ADVIA Centaur XPT as r=0.934 and r=0.907, respectively. Also, the correlation coefficient was found between Roche Cobas e601 and Siemens ADVIA Centaur XPT as r=0.906. Conclusions The Roche Cobas assay showed better performance, compared with the other assays. Based on our findings, the chemiluminescence methods in automated systems seem to be expedient.
Objective: Telogen effluvium is one of the chronic diseases that affect the quality of life (QoL) in women. The study aimed to evaluate the RDW/MCV ratio and its correlation with ferritin in Telogen Effluvium patients and to reveal their potential role in the etiopathogenesis of Telogen effluvium. Material and Methods: We retrospectively evaluated the medical data of 250 patients who were admitted to the dermatology outpatient clinic between September 2020 and December 2020 with a diagnosis of Telogen effluvium. The control group was created retrospectively from the medical records of 250 healthy individuals. HB, HCT, MPV, MCV, RDW, ferritin, and MCV/RDW ratio of both groups were compared and evaluated statistically. Results: All of the Telogen effluvium patients were women in terms of gender. The mean age of the patient group was 33,11±9,66 years and the mean age of the control group was 34,98±12,37 years. The ratio of MCV/RDW, MPV, MCV, and ferritin is lower in the group with Telogen effluvium compared to the control group and a statistically significant difference was found(p<0.05). However, the correlation between MCV/RDW ratio and ferritin was evaluated in Telogen effluvium patients, and no significant differences were found (p>0.05). Conclusion: Iron deficiency anemia is thought of as a factor in female patients with telogen effluvium. Although the data shows the correction of iron deficiency is insufficient telogen effluvium, we proposed that laboratory tests should be routinely used in the diagnosis and treatment phase of patients who apply with the complaint of hair loss.
Objective Acne vulgaris is a multifactorial disease of the pilosebaceous unit. As the most common skin disease, it may affect approximately 85% of the young population. Survivin, a member of the inhibitors of the apoptosis (IAP) gene family, can inhibit apoptosis and regulate cell division and proliferation. In the study, we aimed to investigate the potential role of serum survivin in acne vulgaris. Methods Forty individuals who were diagnosed with acne vulgaris and forty healthy subjects as the control group were enrolled in the study. Venous blood samples were collected from each participant, and the serum levels of survivin were measured by enzyme‐linked immunosorbent assay (ELISA). Statistical analysis was performed using SPSS software version 25. Results The serum survivin levels were statistically significant between the groups, and the levels of survivin were measured as acne vulgaris patients group 153.44 and control group 104.17 pg/ml, respectively (p < 0.018). When the serum survivin levels were compared according to gender, females had higher levels of survivin than the males (168.16 versus 50.45 pg/mL, p = 0.001). A significant correlation was found between acne severity (p = 0.017) and Scale for Acne Scar severity (SCAR‐S) score (p = 0.001) according to the survivin levels. In terms of age, no significant relationship was found between age and survivin (p = 0.4048). Conclusion Elevated serum levels of survivin were determined in acne vulgaris. Moreover, there was a significant correlation between acne stage and SCAR‐S score according to survivin levels.
Objective: The measurements of electrolytes are an indispensable part of the routine tests performed in clinical biochemistry laboratories. In the present study, we aimed to evaluate Na, K, and Cl electrolytes with the ISE method in the Mindray BS-800M and Beckman Coulter AU5800 devices. Material and methods: The serum samples were obtained from the healthy volunteers admitted to the Karapınar State Hospital for control purposes between January and April 2021. The sample probe was conducted using the same indirect method in the Mindray BS-800M and Beckman Coulter AU5800 devices, which is an individual sample probe for the ISE method. Results: While the comparative measurements were performed on different devices, the correlations between the electrolytes were found as follows: Na [r=0.964, 95% CI (0.52-0.90)], K [r=0.995, 95% CI (0.09-0.12)], and Cl [r=0.972, 95% CI (0.69-1.12)]. Moreover, a correlation was also found between these results. Conclusion: A consistency between the measured Na, K, and Cl electrolytes was determined on the different analyzers. Also, a positive correlation was determined between those electrolytes. We consider that further and comprehensive studies are needed to elucidate these results.
