ABSTRACT

OBJECTIVE: This aim of this study was to evaluate hemoglobin and hematocrit values of polycythemia vera and secondary polycythemia patients with updated World Health Organization thresholds. In addition, by determining our own threshold values, we aimed to demonstrate the necessity of bone marrow biopsy and genetic analysis to be used for further diagnosis in patients with high-normal hematocrit and hemoglobin values. METHODS: A cross-sectional and retrospective study was performed with the medical records of patients from Eskisehir City Hospital hematology clinics and outpatient clinics between July 1, 2019 and July 1, 2020. The study included patients with polycythemia, divided into two groups according to polycythemia vera and secondary polycythemia. A bone marrow biopsy was performed on patients with either Janus kinase mutation positivity and/or subnormal erythropoietin levels. Receiver operating characteristics analysis was used to find threshold values, and the diagnostic efficiency of these values in differentiating World Health Organization thresholds in 2008 and 2016 was evaluated. RESULTS: A total of 73 patients were included. The median age was 43.5 years (min: 18; max: 84). The hematocrit value of 54.1 was predicted to diagnose polycythemia vera with a sensitivity of 45% and a specificity of 80%. Subsequent analysis revealed that an hemoglobin value of 17.7 was indicative of diagnosing polycythemia vera with a sensitivity of 60% and a specificity of 63%. The mean follow-up length was 6.4 months (2-12). CONCLUSION: Our study demonstrated that modified World Health Organization criteria might lead to unnecessary additional tests for polycythemia vera patients with high-normal hemoglobin and hematocrit values.

ABSTRACT

Aim    Early diagnosis and treatment is very important in acute coronary syndromes (ACS). Previous studies showed that not all non-ST elevation myocardial infarction (NSTEMI) patients should be considered and treated in the same way. The systemic immune-inflammation index (SII), which is an easily accessible, rapidly computed, and cost-effective parameter, was evaluated in this study to determine the optimal intervention time for NSTEMI.Material and methods    469 patients diagnosed with ACS were included to the study. STEMI and NSTEMI patients were compared according to their SII. Univariate and binary logistic regression analysis were performed to determine which parameters have a significant effect on the discrimination of types of myocardial infarction.Results    The mean age of the patients was 61.43±11.52 yrs, and 348 (74.2 %) were male. NSTEMI patients with an SII value higher than 768×109 / l may be assumed to be STEMI (p<0.001). Univariate analysis and binary logistic regression showed that only SII and hypertension had statistically impact on differentiation of STEMI and NSTEMI. In addition, SII value of 1105×109 / l was the cut-off point for discrimination of cardiovascular survival (p<0.001, AUC =0.741). This study was performed to find out which NSTEMI patients should be treated percutaneously immediately after first medical contact according to SII. It was found that, SII value of higher than 768×109 / l is related with STEMI.Conclusion    In conclusion, NSTEMI patients with a SII value higher than 768×109 / l may be considered as STEMI and treated with in 120 min after first contact. In addition, SII was found to be a cardiovascular mortality predictor after myocardial infarction, and this may be used for identifying high-risk patients after percutaneous coronary intervention.

ABSTRACT

In order to replenish iron stores and bring hemoglobin (Hb) levels back to normal, oral iron is the primary treatment option for women with iron deficiency anemia (IDA). This study investigated the efficacy and side effects of daily versus alternate-day, given single doses versus double doses oral iron supplementation for treating IDA. A retrospective cohort study was performed between 2021 and 2022, including 120 patients. Study group were divided into 4 age-sex-matched groups; Group I (n = 30) and Group II (n = 30) which were received ferrous sulphate tablets daily in single or double doses, respectively, containing 60 mg of elemental iron each. Groups III (n = 30) and IV (n = 30) were received a single and double dose on alternate days, respectively. The primary outcome was the mean difference in Hb from baseline at week 4. Gastrointestinal (GI) side effects were accepted as a secondary outcome. The daily single dose and alternate day double dose groups had median Hb changes of 2.3 (2.1) and 2.6 (1.8) g/dL. The differences in Hb between Groups I and II, I and III, and Groups IV and II, IV and III were significant (P < .001, P = .001, P < .001, and P < .001, respectively). There is no significant difference between groups regarding improving iron parameters such as serum iron, total iron binding capacity, transferrin saturation, and ferritin. The incidence of GI side effects were greater in double doses than in single doses of daily or alternate-day therapies (43.3% and 30% vs 10% and 3.3%). Daily or alternate-day double dose resulted in more side effects but less therapeutic efficacy in women with IDA. To find the best supplementation method, randomized controlled trials with a larger sample of participants, longer study lengths, and various iron doses may be helpful.

ABSTRACT

Objective    Early diagnosis of hypertension (HT) is a critical issue for physicians. This study was conducted to determine if morning surge blood pressure (MSBP) could be used to predict future HT. The study also examined which demographic data in a regression model might help to detect future HT without any invasive procedure.Material and methods    A young population between 18 and 40 yrs of age was included in the study. MSBP and demographic data were used to determine an optimal model for predicting future HT by using Bayesian information criteria and binary logistic regression.Results    1321 patients with 24 hr ambulatory blood pressure monitoring were included in this study. The odds ratio of 10 units of increase in diastolic MSBP was 1.173511 in the model, which indicates that a 10 mmHg increase in diastolic MSBP increases the odds of future HT in the patient by 17.4 %. The odds ratio of age was 1.096365, meaning that at each age above 18 yrs, the patients' odds of future HT rise by 9.6 %. The odds ratios for gender (male) and previous HT were 1.656986 and 3.336759, respectively. The odds of future HT in males were 65 % higher than for females, and a history of HT implies that the odds of future HT were higher by 230 %.Conclusion    Diastolic MSBP can be used to predict HT in young individuals. In addition, age, male gender, and previous HT add more predictive power to diastolic MSBP. This statistically significant, predictive model could be useful in lessening or preventing future HT.

ABSTRACT

Aim    Mortality prediction is very important for more effective treatment of patients with acute coronary syndrome. Hematological and lipid parameters have been used for this purpose, as this approach is non-invasive and cost effective. In this study, our aim was to evaluate which parameter predicts mortality most accurately.Material and Methods    Data of 554 patients with at least one total coronary artery occlusion were collected retrospectively. Receiver operating characteristic curves were used to determine the optimal cut-off points of Neu / HDL, Neu / Lym, Mono / HDL, Trig / HDL, HDL / LDL, Plt / Lym and Lym / HDL according to long-term cardiovascular survival. Median follow-up time was 520 days, and 30 patients died.Results    The mean age was 60.96±0.50 yrs. The area under the curve (AUC) for Neu / HDL was 0.830 (p<0.001, 95 % confidence interval [CI]: 0.753 to 0.908). The cut-off point was 0.269, with a sensitivity of 74.2 % and a specificity of 74.2 %. The AUC for Neu / Lym was 0.688 (p<0.001, 95 % CI: 0.586 to 0.790). The cut-off point was 5.322, with a sensitivity of 67.7 % and a specificity of 67.1 %. The Neu / HDL (hazard ratio, HR [confidence interval, CI]: 0.202 [0.075-0.545], p=0.002) and Neu / Lym (0.306 [0.120-0.777], p=0.013) were associated with increased risk of death according to multivariate Cox regression analysis.Conclusions    Neu / HDL offers a better long-term mortality prediction than Neu / Lym, Mono / HDL, Trig / HDL, HDL / LDL, Plt / Lym, or Lym / HDL after treatment of total coronary artery occlusion.
