A nationwide multicentre study in Turkey for establishing reference intervals of haematological parameters with novel use of a panel of whole blood

IntroductionA nationwide multicentre study was conducted to establish well-defined reference intervals (RIs) of haematological parameters for the Turkish population in consideration of sources of variation in reference values (RVs). Materials and methodsK2-EDTA whole blood samples (total of 3363) were collected from 12 laboratories. Sera were also collected for measurements of iron, UIBC, TIBC, and ferritin for use in the latent abnormal values exclusion (LAVE) method. The blood samples were analysed within 2 hours in each laboratory using Cell Dyn and Ruby (Abbott), LH780 (Beckman Coulter), or XT-2000i (Sysmex). A panel of freshly prepared blood from 40 healthy volunteers was measured in common to assess any analyser-dependent bias in the measurements. The SD ratio (SDR) based on ANOVA was used to judge the need for partitioning RVs. RIs were computed by the parametric method with/without applying the LAVE method. ResultsAnalyser-dependent bias was found for basophils (Bas), MCHC, RDW and MPV from the panel test results and thus those RIs were derived for each manufacturer. RIs were determined from all volunteers’ results for WBC, neutrophils, lymphocytes, monocytes, eosinophils, MCV, MCH and platelets. Gender-specific RIs were required for RBC, haemoglobin, haematocrit, iron, UIBC and ferritin. Region-specific RIs were required for RBC, haemoglobin, haematocrit, UIBC, and TIBC. ConclusionsWith the novel use of a freshly prepared blood panel, manufacturer-specific RIs’ were derived for Bas, Bas%, MCHC, RDW and MPV. Regional differences in RIs were observed among the 7 regions of Turkey, which may be attributed to nutritional or environmental factors, including altitude

Long-term outcomes of the global tuberculosis and COVID-19 co-infection cohort

Background: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. Methods: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. Results: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). Conclusions: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes

DETERMINATION OF SERA NGAL LEVELS IN PATIENTS WITH LUNG CANCER AND ITS RELATION WITH APOPTOSIS

WOS: 000427344600043The NGAL synthesis induces in neoplasms; therefore, probably, it is benefited from the level of this protein for the determination of carcinogenesis and the progress stages of human tumors. In this study, it was aimed to investigate the expression of NGAL (neutrophil gelatinase associated lipocalin) in lung cancer patients and its relation with apoptosis. The study was conducted on the patients between the ages of 40 and 70 years accepted by the Thoracic Surgery Clinic (Selcuk University, Faculty of Medicine) based on their lung cancer diagnosis. The patients aged between 40 and 70 were included in the study from the thoracic surgery clinic of the Selcuk University as they were administered into the clinic based on their lung cancer diagnosis and had operation before. Patients who have acute stroke, rheumatic diseases, chronic kidney disease, congestive heart failure, chronic infection and other organ and system cancers (except lung cancer) were excluded from the study. Two groups including a lung cancer group (N=40) and a normal group (N=40) were formed to determine the NGAL and M30 levels in sera of patients using the ELISA method. According to the analysis results, the NGAL levels for the lung cancer group and the normal group were observed as 424.03 +/- 74.49 and 374.04 +/- 90.34 ng/mL, respectively. This increase in the lung cancer group was found statistically significant according to the normal group (p < 0.01). The M30 levels, marker for apoptosis in circulation, were obtained as 144.08 +/- 45.91 and 118.76 +/- 46.16 U/L for the lung cancer group and the normal group, respectively. This increase in the lung cancer group was found statistically significant according to the normal group (p < 0.01). A positive correlation was obtained between the NGAL and M30 data by means of Spearman's correlation test (r(40)=0.58, p < 0.01). The antigen levels of caspase 3, 8 and 9 were determined by the immunohistochemical staining methods in the samples of cancerous tissues and normal tissues adjacent to the cancerous tissue, and the apoptotic indexes were calculated. The apoptotic indexes of the cancerous tissues were significantly lower than the normal tissues (p < 0.01). This result demonstrates that the predominant type of cell death might be other cell death pathways rather than the apoptotic pathways in lung cancer. In addition, these results support the opinion about the fact that apoptosis may be inhibited by cancer cells in cancerous tissues. The significant increase in the M30 and NGAL levels supports the claims of the previous studies about the fact that it causes the consumption of cellular iron reserves and NGAL induced apoptosis in cancer patients

Sex-specific analysis in Behcet's disease reveals higher genetic risk in male patients

Objectives: Behcet's disease tends to be more severe in men than women. This study was undertaken to investigate sex-specific genetic effects in Behcet's disease. Methods: A total of 1762 male and 1216 female patients with Behcet's disease from six diverse populations were studied, with the majority of patients of Turkish origin. Genotyping was performed using an Infinium ImmunoArray-24 BeadChip, or extracted from available genotyping data. Following imputation and extensive quality control measures, genome-wide association analysis was performed comparing male to female patients in the Turkish cohort, followed by a meta-analysis of significant results in all six populations. In addition, a weighted genetic risk score for Behcet's disease was calculated and compared between male and female patients. Results: Genetic association analysis comparing male to female patients with Behcet's disease from Turkey revealed an association with male sex in HLA-B/MICA within the HLA region with a GWAS level of significance (rs2848712, OR = 1.46, P = 1.22 x 10-8). Meta-analysis of the effect in rs2848712 across six populations confirmed these results. Genetic risk score for Behcet's disease was significantly higher in male compared to female patients from Turkey. Higher genetic risk for Behcet's disease was observed in male patients in HLA-B/ MICA (rs116799036, OR = 1.45, P = 1.95 x 10-8), HLA-C (rs12525170, OR = 1.46, P = 5.66 x 10-7), and KLRC4 (rs2617170, OR = 1.20, P = 0.019). In contrast, IFNGR1 (rs4896243, OR = 0.86, P = 0.011) was shown to confer higher genetic risk in female patients. Conclusions: Male patients with Behcet's disease are characterized by higher genetic risk compared to female patients. This genetic difference, primarily derived from our Turkish cohort, is largely explained by risk within the HLA region. These data suggest that genetic factors might contribute to differences in disease presentation between men and women with Behcet's disease.National Institute of Arthritis and Musculoskeletal and Skin Diseases of the National Institutes of Health [R01AR070148]Funding This work was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases of the National Institutes of Health grant number R01AR070148
