Association of mortality and endothelial dysfunction with serum ADMA level in COVID-19 patients.

Objectives: To investigate the role of asymmetric dimethylarginine (ADMA) level in predicting intensive care and mortality in patients affected with coronavirus disease 2019 (COVID-19). Methods: This retrospective, cross-sectional study was conducted at Sakarya University Training and Research Hospital (Sakarya, Turkey) between April and August of 2020. We enrolled patients who were diagnosed with COVID-19 via real-time reverse-transcription polymerase chain reaction and admitted to the intensive care (Severe COVID-19; S-COVID) or non intensive care (Moderate COVID-19; M-COVID). We then analyzed the relationship of the ADMA level with various parameters between S-COVID and M-COVID groups. Results: This study included 87 patients, comprising 43 females and 44 males, with a mean age of 61 and 71.50 years, respectively. The male/female distribution was 22/25 (46.8%/53.2%) in the M-COVID group and 22/18 (55%/45%) in the S-COVID group. The hospitalization time, white blood cell count, neutrophil count, lymphocyte-to-albumin ratio, international normalization ratio, D-dimer, troponin, ferritin, lactate dehydrogenase, C-reactive protein, procalcitonin, erythrocyte sedimentation rate, fibrinogen, lactate, ADMA, and mortality rate were significantly higher (p < 0.05). In contrast, lymphocyte, total cholesterol, high-density lipoprotein, calcium, and albumin values were lower (p < 0.05) in the S-COVID group than in the M-COVID group. While the mortality rate was 55% in S-COVID patients, no mortality was detected in M-COVID patients (p < 0.05). Moreover, ADMA level was 6618 ± 3000 (6400) in S-COVID patients and 5365 ± 3571 (3130) in M-COVID patients, indicating a statistically significant difference (p = 0.012). Conclusion: The asymmetric dimethylarginine level increases in severe outcomes; hence, it can potentially predict severity in patients with COVID-19.

The effect of Thyroid Autoimmunity on Dyslipidemia in patients with Euthyroid Hashimoto Thyroiditis.

BACKGROUND & OBJECTIVE: The relationship between thyroid disorders and dyslipidemia has now been clearly demonstrated, but the relationship between thyroid autoimmunity and dyslipidemia in euthyroid patients is still controversial. Our aim in this study was to determine whether there is a risk of dyslipidemia in our patients with euthyroid hashimoto thyroiditis. METHODS: Fifty-five autoantibody positive hashimoto patients and 55 antibody negative control groups who came to Sakarya University Medicine Faculty Endocrinology Outpatient Clinics between January 2018 and November 2019 were included in our case control study. The groups were similar in terms of age, cardiovascular risk factors and BMI. Both groups were compared according to the lipid profile results. RESULTS: All type of lipids; including LDL (p = 0.008), HDL (p = 0.041), triglyceride (p = 0.045) and total cholesterol (p = 0.002), were higher in the patient group, and these differences were statistically significant. Anti-TPO and Anti-TG antibody titers and lipid levels were evaluated by separate correlation analysis. There was a significant positive correlation between Anti-TPO and LDL (r = 0.331, p <0.001), triglyceride (r = 0.267, p = 0.005) and total cholesterol (r = 0.316, p = 0.001), however no significant correlation was observed between Anti-TPO and HDL. Similarly, there was a significant positive correlation between Anti-TG and LDL (r = 0.318, p = 0.001), triglyceride (r = 0.218, p = 0.022), and total cholesterol (r = 0.301, p = 0.001), but HDL correlation relationship was not detected. CONCLUSION: The relationship between thyroid autoimmunity and dyslipidemia has been demonstrated in our study even in the euthyroid phase. Whether antibody positive patients should be followed more closely for dyslipidemia and cardiovascular events is still controversial. This question will be answered with larger randomized controlled trials.

The effect of short-term intensive insulin therapy in newly-diagnosed Type-2 diabetic patients.

OBJECTIVES: We aimed to determine the effect of short-term intensive insulin therapy (SIIT) on long-term glycemic control in newly-diagnosed Type-2 diabetes mellitus (nT2DM) patients. METHODS: In this retrospectively study conducted at Sakarya University Medical Faculty Training and Research Hospital Outpatient Clinic between 2016 and 2019, 65 nT2DM patients were enrolled soon after their SIIT was initiated and were followed for at least a year. Intensive insulin treatment was discontinued after three or 12 months in a total of 65 (23-73-year-old) patients who had been newly diagnosed with T2DM. Intensive insulin therapy was discontinued when glycemic control and the target Glycated Hemoglobin (HbA1c) level had been attained, after which oral anti-diabetic drug (OAD), long-term insulin, and diet therapies were pursued. RESULTS: There was a significant decrease in mean HbA1c from 11.25±1.96% to 6.67±1.07%. Fasting plasma glucose (FPG) was found to be an independent predictor of whether intensive insulin therapy could be discontinued after three months in a model that included FPG, HbA1c, and body mass index measured at baseline. Patients with FPG>13.8 mmol/L were 7.6 times more likely to require intensive insulin therapy beyond three months. There were significant decreases in HbA1c and low-density lipoprotein-cholesterol concentration, but no change in C-peptide between baseline and 3 months of therapy. CONCLUSION: These results demonstrate that in nT2DM patients, intensive insulin therapy could be effective on long-term glycemic control and high FPG prior to three months of SIIT may predict poor long-term glycemic control.

MYELOLIPOMA COEXISTENCE WITH GLUCOCORTICOID AND ANDROGEN SECRETING ADRENOCORTICAL CARCINOMA: SLOW AND BENIGN CLINICAL COURSE.

We present a case of androgen and glucocorticoid secreting adrenocortical carcinoma with concomitant myelolipoma. A giant adrenal tumor which was initially nonfunctional was reassessed four years later due to the patient's refusal to treat. The patient was a 48-year-old woman with hypertension and acne lesions on the face. Laboratory findings were consistent with glucocorticoid and androgen hypersecretion. Computed tomography revealed a heterogeneously contrasting mass of 145x118x100 mm with lobular contour and soft tissue areas. The patient underwent left laparoscopic transperitoneal adrenalectomy with three port technique. There were no complications in the perioperative period. The resected specimen weighed 850 grams. Pathological findings showed a combination of myelolipoma-adrenal cortical cancer. In the postoperative period, hypertension improved and the hormone panel was normalized. Postoperative computed tomography and PET-CT showed no residual mass and metastasis. Although imaging is compatible with benign masses such as myelolipoma, coexistence of ACC-myelolipoma should be kept in mind and functional evaluation should be performed.

Doppler ultrasonographical findings in the differential diagnosis of post-partum thyroiditis.

OBJECTIVE: To investigate the effects of haemodynamic indices on colour Doppler ultrasound in differential diagnosis in patients with postpartum thyroiditis and with Graves' disease. METHODS: The cross-sectional study was conducted at the Endocrinology Polyclinic of Medical Park Hospital, Ordu, Turkey, from March 2017 to May 2018 and comprised patients referred from the Gynaecology Department for routine check-up after parturition within the first 6 months. The patients were divided into two groups. Group 1 had postpartum thyroiditis patients and Group 2 had those of Graves' disease. In both groups, parameters measured were peak systolic velocity, end-diastolic velocity and resistive index of the inferior thyroid artery with proper angle (45-60°) on colour Doppler ultrasound. Data was analysed using SPSS 20. RESULTS: Of the 42 subjects,18(42.85%) were in Group 1 and 24(57.14%) were in Group 2. Peak systolic velocity and end-diastolic velocity values of the inferior thyroid artery were higher in Group 2 compared to Group 1 (p<005). (p<0.05), while the resistive index value was significantly higher in Group 1 compared to Group 2. CONCLUSIONS: Due to its wide availability, the use of colour Doppler ultrasound parameters indicating parenchymal perfusion were found to be broadly useful in distinguishing between postpartum thyroiditis and Graves' disease.

The role and importance of auxiliary tests in differential diagnosis in patients with mildly high basal 17-OH-progesterone levels in the evaluation of hirsutism

Background/aim: In the differential diagnosis of hirsutism, early follicular basal 17-OH-progesterone levels sometimes overlap with the diagnosis of late onset congenital adrenal hyperplasia (LOCAH) and other causes of hyperandrogenism. This study aims to investigate the role of some common tests and clinical findings in differential diagnosis in such cases. Materials and methods: One hundred seventy-five female patients with hirsutism and mildly high initial 17-OH-progesterone levels (2-10 ng/mL) were included in the study. The cases were divided into three groups according to their diagnosis: LOCAH (n = 16, mean age = 26.1 ± 6.9), polycystic ovary syndrome (PCOS) (n = 122, mean age = 23.9 ± 5.1), and intracranial hypertension (IH) (n = 37, mean age = 25.2 ± 7.3). Clinical signs and symptoms, such as menstrual irregularity and hirsutism score, and hormone levels including total testosterone and dehydroepiandrosterone sulfate (DHEAS), were compared between the groups. Results: There was no difference between the groups with PCOS, LOCAH, and IH for total testosterone level results (P = 0.461). The DHEAS level was higher in the PCOS group than in the LOCAH group (449.6 ± 151.14 vs. 360.31 ± 152.40, P = 0.044). While there was no difference between the PCOS and LOCAH groups in terms of menstrual irregularity (P = 0.316), the hirsutism score for IH was significantly lower than those of PCOS and LOCAH (9.2 vs. 12.2 and 11.1, respectively; P < 0.001). Basal 17-OH-progesterone levels were higher in the LOCAH group than in the other groups (P = 0.016). Conclusion: While DHEAS level was lower in LOCAH than in PCOS, it was not different from that in IH. While the severity of hirsutism was higher in LOCAH than in IH, it was not different from that in PCOS. Menstrual irregularity was similar between PCOS and LOCAH. According to these results, although the auxiliary tests and clinical findings for the diagnosis of LOCAH contribute to the clinical interpretation, they are not superior to the 17-OH-progesterone level for diagnosis.

Hemogram parameters in the patients with subacute thyroiditis.

BACKGROUND &OBJECTIVE: Subacute Granulomatous Thyroiditis (De Quervain's Thyroiditis) is an acute painful inflammatory disease of the thyroid. We aimed to investigate easily accessible and cheap hemogram based parameters of Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), and Mean Platelet Volume (MPV) in the follow up of inflammatory thyroid disease. METHODS: Patients admitted to Sakarya University Education and Research Hospital Endocrinology and Metabolism Outpatient Clinic and diagnosed as Subacute Granulomatous Thyroiditis between May 2017 and November 2018 were included in the study. Hemogram, thyroid function tests and acute phase values of these patients were recorded and compared with the values after treatment and disease recovery. On the sixth month, thyroid function tests were repeated and the rate of permanent hypothyroidism was screened. The relationships between initial hemogram parameters and acute phase reactants were evaluated. RESULTS: Total 71 patients were included in our study. 60 (84.5%) were female and 11 (15.5%) were male. The F/M ratio was found to be 6/1. Mean age was 43 ± 9.95 years. Receiver Operating Characteristics (ROC) Curve Analysis was performed and values for Area Under the Curve (AUC) for NLR and PLR, respectively, were 0.739 (95% CI 0.657-0.820 p<0.0001) and 0.772 (95% CI 0.694-0.850 p<0.0001), which are significant and associated with disease activity. However, the AUC for MPV parameter was: 0.578 (95% CI 0.484-0.672 P: 0.10) and was not significant. The cut off values defined as 2.4 (80% sensitivity and 51% specificity) for NLR and 146.84 (83% sensitivity and 54% specificity) for PLR for the acute phase of the disease. In the Correlation Analysis, NLR and PLR values were significantly correlated with ESR and CRP parameters, which are the most commonly used acute phase reactants. CONCLUSION: According to the present study, we believe that the NLR and PLR parameters will be of benefit in the follow-up the disease, accurately demonstrate the inflammatory load in the acute phase of the disease, and correlate with the common acute phase reactants.

Is Change in Hemoglobin Level a Predictive Biomarker of Tyrosine Kinase Efficacy in Metastatic Renal Cell Carcinoma? A Turkish Oncology Group Study.

BACKGROUND: There are insufficient predictive markers for renal cell carcinoma (RCC). METHODS: A total of 308 metastatic RCC patients were analyzed retrospectively. RESULTS: The increased hemoglobin (Hb) group had significantly higher progression-free survival and overall survival (OS) compared with the decreased Hb group at 11.5 versus 6.35 months (p < .001) and 21.0 versus 11.36 months (p < .001) respectively. The 1- and 3-year OS rates were higher in the Hb increased group, i.e., 84% versus 64% and 52% versus 35% respectively. CONCLUSIONS: The present study showed that increased Hb levels after tyrosine kinase inhibitor therapy could be a predictive marker of RCC.

Predictors of periprocedural complications of carotid artery stenting - a multivariate analysis of a single-centre experience.

BACKGROUND: Carotid artery stenting (CAS) is currently used as an alternative treatment to carotid endarterectomy (CEA). The objective of this study was to analyse our 5-year experience performing CAS. Secondarily, we sought to determine independent risk factors which predict periprocedural complications. PATIENTS AND METHODS: A total of 146 patients who underwent 153 CAS procedures were analysed. The majority of patients (123, 84.2%) had symptomatic carotid stenosis. Demographic and interventional data, angiographic lesion characteristics, and periprocedural complications were recorded. Using univariate and multivariate logistic regression analyses, risk factors associated with adverse clinical outcomes were determined. RESULTS: Periprocedural neurological complications, including four (2.7 %) major strokes, three (2 %) transient ischaemic attacks, one (0.7%) amaurosis fugax, and two (1.3 %) cases of hyperperfusion syndrome occurred in ten (6.8%) patients. The incidence of periprocedural complications significantly increased in female patients (r = 0.214, p = 0.009) and patients with longer lesions (r = 0.183, p = 0.027), contralateral stenosis ≥50 % (r = 0.222, p = 0.007), the presence of complicated plaques (r = 0.478, p < 0.001) and inadequate glycaemic control (r = 0.259, p = 0.002). Multivariate regression analysis also determined four variables to be potential independent risk factors for 30-day adverse events: higher age (Odds ratio [OR] = 1.283; 95 % CI, 1.051 to 1.566, p = 0.014); longer lesions (OR = 1.459, 95 % CI, 1.124 to 1.893, p = 0.004); higher tortuosity index (OR = 1.015, 95 % CI, 1.001 to 1.030, p = 0.034), and the presence of complicated plaque morphology (OR = 4.321, 95 % CI, 1.621 to 10.23, p = 0.001). CONCLUSIONS: Patient and lesion characteristics including age, lesion length, complicated plaque morphology and tortuosity index, may be associated with periprocedural complications.

Echocardiographic Evaluation of Biventricular Function in Patients with Euthyroid Hashimoto's Thyroiditis.

OBJECTIVE: The aim of this study was to evaluate the left (LV) and right (RV) ventricular function in euthyroid Hashimoto's thyroiditis (eHT) patients. SUBJECTS AND METHODS: Forty-five patients diagnosed with eHT and 45 age- and gender-matched control subjects were enrolled in this study. Echocardiographic parameters reflecting RV and LV functions such as chamber dimensions, ejection fraction, fractional shortening, conventional and tissue Doppler-derived early and late filling velocities (E, A, E', A'), isovolumic relaxation (IVRT) and contraction (IVCT) times, ejection time (ET), deceleration time (DT), Tei index, pulmonary acceleration time (PAcT) and tricuspid annular plane systolic excursion (TAPSE) of patients with eHT were compared to those of control subjects using the paired-samples t test or Wilcoxon signed-rank test. RESULTS: Regarding the LV function, compared to the controls patients with eHT had a higher LV-Tei index (0.6 ± 0.2 vs. 0.4 ± 0.1, p < 0.001), higher DT (p < 0.001) and IVRT (p < 0.001) values, and higher E/E' ratios (p = 0.04). In contrast, the peak E wave velocity (p = 0.02), E/A ratio (p = 0.01) and ET (p = 0.02) were significantly lower in the eHT group than amongst the controls. The RV, Tei index (0.40 ± 0.11 vs. 0.28 ± 0.07, p < 0.001), TAPSE (2.0 ± 0.3 vs. 2.2 ± 0.2 mm, p < 0.001), PAcT (124.3 ± 22.6 vs. 149.4 ± 18.3 ms, p < 0.001), A' (p = 0.007) and IVCT (p = 0.001) were significantly higher in patients with eHT than the controls. However, the tricuspid E/A ratio (p = 0.01), E' (p = 0.03) and E'/A' ratio (p = 0.001) were significantly lower in the eHT patients than the control group. CONCLUSIONS: This study demonstrated that both RV and LV functions were impaired in patients with eHT.

Neutrophil to lymphocyte ratio might help prediction of acute myocardial infarction in patients with elevated serum creatinine.

BACKGROUND AND OBJECTIVE: Diagnostic performance of troponin assays is affected by renal insufficiency. Neutrophil to lymphocyte ratio(NLR) is an independent predictor of acute coronary syndrome. Our objective was to evaluate performance of NLR in diagnosing acute myocardial infarction (AMI) among patients with elevated serum creatinine. METHODS: Patients with elevated creatinine levels evaluated for coronary artery disease were included (n=284). Patients were divided into two groups according to having AMI or non-specific chest pain. AMI diagnosis was made based on clinical and laboratory data, including serial EKG and cardiac enzymes, ECHO and coronary angiography. RESULTS: Troponin, neutrophil, and NLR were found to be higher in patients with AMI, compared to patients without AMI (P= 0.001, P= 0.001 and P=0.028, respectively). ROC curve analysis for NLR in diagnosing AMI was significant (AUC: 0.607; P=0.003). Sensitivity, specificity, LR +, LR-, PPV and NPV for NLR>7.4 were found as 42.3%, 74.7%, 1.68%, 0.77%, 77% and 40%, respectively. Logistic regression analysis revealed that patients whose NLR>7.4 were 2.18 times as likely to have AMI. CONCLUSIONS: NLR can be used as an independent predictor of AMI in patients with renal insufficiency. This seems to get more important in the era of high sensitivity troponin assays. Our results might also help in early diagnosis of AMI in this high risk population while serial cardiac enzyme results are pending.

The effects of zoledronic acid treatment on depression and quality of life in women with postmenopausal osteoporosis: A clinical trial study.

BACKGROUND: Osteoporosis affects quality of life (QoL) and may lead to depression in women. The purpose of this study was to evaluate the effects of zoledronic acid (ZA) treatment on depression and QoL in women with postmenopausal osteoporosis (PO). MATERIALS AND METHODS: A total of 88 newly diagnosed women with PO were included in this study. All patients were treated with once-yearly ZA (5 mg). A QoL questionnaire from the European Foundation for Osteoporosis and Beck Depression Inventory were given to patients at baseline and at 12 months. The results for baseline and post - 12th month were compared, and bone mineral density (BMD) levels were compared. RESULTS: The consumption of once-yearly ZA (5 mg) treatment increases BMD at levels of lumbers 1-4 (P = 0.026), total Hip T score's P value is same as femoral neck (P: 0,033). ZA 5 mg treatment also improved QoL (P = 0.001) and reduced depression (P = 0.001). CONCLUSION: ZA treatment increases BMD levels and QoL while reducing depression. Once-yearly ZA (5 mg) may be considered for postmenopausal women as a first-line treatment.

Acoustic Voice Analysis in Subclinical Hyperthyroidism.

OBJECTIVE: To investigate the effect of subclinical hyperthyroidism on voice quality using acoustic analysis. STUDY DESIGN: Cross-sectional comparative study. Place and Duration of the Study: Department of Endocrinology and Metabolism, Ankara Diskapi Yildirim Beyazit Research and Education Hospital, Ankara, Turkey, from January to June 2020. METHODOLOGY: A total of 115 participants, with 60 patients with subclinical hyperthyroidism and 55 healthy volunteers, were evaluated and compared. Healthy volunteers with similar age and gender distributions were also evaluated and compared. Acoustic variables including average fundamental frequency (F0), relative average perturbation (RAP), jitter, shimmer, noise-to-harmonic ratio (NHR), and voice turbulence index (VTI) were measured and recorded. RESULTS: In the patient group, acoustic voice analysis results were obtained for F0 224.97%, jitter 0.85%, RAP 0.51%, shimmer 3.16%, NHR 0.12 dB, and VTI 0.047, respectively. In the control group, these respective values were 219.60%; 0.74%; 0.46%; 3.11%; 0.12 dB; and 0.045, respectively. There was no statistically significant difference between the groups (p>0.05). CONCLUSION: Subclinical hyperthyroidism does not cause a significant change in voice quality. KEY WORDS: Acoustic analysis, Subclinical hyperthyroidism, Voice, Frequency.

Glycemic responses to whole grain sourdough bread versus refined white bread in patients with gestational diabetes.

BACKGROUND: Nutritional therapy remains a key tool for prevention and management of gestational diabetes (GDM). Carbohydrate type and absorption rate rather than the carbohydrate amount have more impact on postprandial glucose (PPG) levels in GDM. The effect of refined white bread and whole grain sourdough bread on glycemic indexes were compared in GDM patients. METHODS: A total of 43 patients with GDM and 38 healthy pregnant women were included. A similar breakfast menu was given to both groups of patients at two different times in consecutive weeks; however, different types of bread with the same weight were used for both breakfasts; 1) white wheat (WW) bread, 2) sourdough whole grain wheat (SWGW) bread. Blood glucose, insulin and C­peptide levels were compared before and after breakfast. RESULTS: Fasting glucose, insulin and c­peptide levels were similar between groups (p > 0.05). While the second hour glucose levels were similar between the groups, the first hour results of glucose, insulin and C­peptide levels were lower in the SWGW group (p < 0.05). In the control patients, first hour glucose, insulin and C­peptide levels were also lower in the SWGW group (p < 0.05). CONCLUSION: The WW bread, which is more preferred in daily life routine, causes 45.5% more insulin secretion and 9.6% more first hour postprandial blood glucose compared to SWGW bread both in GDM patients and healthy pregnant women. According to the results of this study, we recommend that sourdough whole grain bread should be preferred in order to increase the success in the management of GDM.

The prognostic significance of erythrocyte sedimentation rate in COVID-19.

OBJECTIVE: There are limited data about the significance of erythrocyte sedimentation rate as a single prognostic parameter for the prognosis and mortality of COVID-19. This study aimed to investigate the diagnostic utility of erythrocyte sedimentation rate as a prognostic factor for the disease severity and mortality in patients with COVID-19. METHODS: A total of 148 consecutive patients with a confirmed diagnosis of COVID-19 and hospitalized at the intensive care unit or non-the intensive care unit were included in the study. The patients were allocated to groups as severe/critical disease versus nonsevere disease and survivors and nonsurvivors. The prognostic role and predictable values of erythrocyte sedimentation rate were analyzed. RESULTS: Erythrocyte sedimentation rate was found to be higher among patients with severe/critical disease compared to those with nonsevere disease (p<0.001) and among nonsurvivors compared to survivors (p<0.001). The logistic regression analysis showed that erythrocyte sedimentation rate was an independent parameter for predicting disease severity and mortality. The role of erythrocyte sedimentation rate in the assessment of severity and mortality in patients with COVID-19 was analyzed using the receiver operating characteristic curve and was found to be significant in both. The analyses suggested that the optimum erythrocyte sedimentation rate cutoff point for disease severity and mortality were 52.5 mm/h with 65.5% sensitivity and 76.3% specificity and 56.5 mm/h with 66.7% sensitivity and 72.5% specificity. CONCLUSION: Our results suggest that erythrocyte sedimentation rate was an independent prognostic factor for severity and mortality in patients with COVID-19.

Has the COVID-19 Pandemic Increased Mortality Among Patients with Cancer Receiving Systemic Anticancer Treatments?

OBJECTIVE: To evaluate the mortality rates in patients receiving anticancer therapy in the coronavirus disease-19 (COVID-19) pandemic period. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Medical Oncology, Sakarya University Training and Research Hospital, Sakarya, Turkey, from December 2017 to May 2020. METHODOLOGY: Only patients who received chemotherapy and immunotherapy were selected and enrolled in the study. All patients (n=3,204) were divided into three groups, namely the first group (1st December 2017-31st May 2018, n=918), second group (1st December 2018-31st May 2019, n=1,147), and the pandemic period group (PPG) (1st December 2019-31st May 2020, n=1,139), according to the period during which they received anticancer treatment. The clinical and demographic characteristics and mortality rates of these three groups of patients were compared. RESULTS: The median age of the total of 3,204 patients was 61 (53-69). In this study, 51.1% (n=1,636) were females and 48.9% were males. The mortality rates were 13.5% (n=124) in the first group, 13.4% (n=154) in the second group, and 13.0% (n=148) in the PPG, respectively. Overall mortality rates did not differ among patients with cancer in the three different six-month periods analysed (p = 0.931). CONCLUSION: There was no unexpected increased in mortality rate among patients undergoing cancer therapy during the COVID-19 pandemic as compared to the previous years of the same timeline. No increase in monthly mortality rates among patients receiving anti-cancer treatment were demonstrated during the pandemic period.

Relationship between serum osteopontin levels and the severity of COVID-19 infection.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an acute inflammatory respiratory disease. Osteopontin (OPN) is a glycoprotein expressed in various cell types, such as bone, immune, smooth muscle, epithelial and endothelial cells. It also acts as a regulator of immune response. The aim of the present study was to reveal the place of serum osteopontin levels in predicting severity among patients with COVID-19. METHODS: This study included 84 patients, 43 female and 45 male. Patients were divided into 2 groups, group 1 non-severe group (n: 48), group 2 severe (n: 40). Demographic data, neutrophil, lymphocyte, platelet, white blood cell counts, albumin, procalcitonin, C­reactive protein (CRP) and OPN levels were recorded. The OPN levels and these inflammatory parameters of the two groups were compared. RESULTS: There were no significant differences in terms of gender (female/male 25/23 vs. 18/22) and platelet count (178 K/µL vs. 191 K/µL) between the groups (p > 0.05). Ages (57.7 ± 17.0 years vs. 71.4 ± 12.8 years), procalcitonin (0.07 vs. 0.24 ng/mL), CRP (17 vs 158 mg/l), neutrophil count (3.7 vs 5.64 K/µL), WBC counts (5.38 vs 7.85 K/µL) and number of deaths (0 vs 26) (p < 0.001). The OPN levels (98.5 vs 13.75 ng/mL, p = 0.002) were found to be statistically higher, in group 2 than group 1. CONCLUSION: The present study showed that OPN can be used to predict the severity in patients with COVID-19.

Does Macrophage Migration Inhibitory Factor predict the prognosis of COVID-19 disease?

INTRODUCTION: The aim of this study is to investigate whether macrophage migration inhibitory factor (MIF) predicts the prognosis of COVID-19 disease. METHODOLOGY: This descriptive and cross-sectional study was conducted on 87 confirmed COVID-19 patients. The patients were separated into two groups according to the admission in the ICU or in the ward. MIF was determined batchwise in plasma obtained as soon as the patients were admitted. Both groups were compared with respect to demographic characteristics, biochemical parameters and prediction of requirement to ICU admission. RESULTS: Forty seven patients in ICU, and 40 patients in ward were included. With respect to MIF levels and biochemical biomarkers, there was a statistically significant difference between the ICU and ward patients (p< 0.024). In terms of ICU requirement, the cut-off value of MIF was detected as 4.705 (AUC:0.633, 95%CI:0.561-0.79, p= 0.037), D-dimer was 789 (AUC:0.779, 95%CI: 0.681-0.877, p= 0.000), troponin was 8.15 (AUC: 0.820, 95%CI:0.729-0.911, p= 0.000), ferritin was 375 (AUC: 0.774, 95%CI:0.671-0.876, p= 0.000), and lactate dehydrogenase (LDH) was 359.5 (AUC:0.843, 95%CI: 0.753-0.933, p= 0.000). According to the logistic regression analysis; when MIF level > 4.705, the patient's requirement to ICU risk was increased to 8.33 (95%CI: 1.73-44.26, p= 0.009) fold. Similarly, elevation of troponin, ferritin and, LDH was shown to predict disease prognosis (p< 0.05). CONCLUSIONS: Our study showed that MIF may play a role in inflammatory responses to COVID-19 through induction of pulmonary inflammatory cytokines, suggesting that pharmacotherapeutic approaches targeting MIF may hold promise for the treatment of COVID-19 pneumonia.

Comparison of real-life data of abiraterone acetate and enzalutamide in metastatic castration-resistant prostate cancer.

To compare enzalutamide (E) and abiraterone acetate (AA) in terms of efficacy, survival and to characterize prognostic factors affecting survival in metastatic castration-resistant prostate cancer (mCRPC) patients. A total of 250 patients treated with E or AA in 5 centers were included. The number of patients with no prostate specific antigen (PSA) decline was higher in the AA group than that in the E group, and the proportion of patients with a PSA decline of ≥ 50% was higher in the E group (p = 0.020). Radiological progression free survival (rPFS) and overall survival (OS) were significantly longer in the E group when compared to that in the AA group (p < 0.001 and p = 0.027, respectively). In the E group, rPFS was significantly longer than that in the AA group in both pre- and post-docetaxel settings (p = 0.010 and p = 0.003, respectively). OS was similar in the pre-docetaxel setting; but in the post-docetaxel setting, E group had a significantly longer OS than the AA group (p = 0.021). In the multivariate analysis performed in the whole patient group, we found that good prognostic factors for rPFS were E treatment, being ≥ 75 years and a PSA decline of ≥ 50% while there was no factor affecting OS. With longer OS and PFS, E seems to be more suitable for mCRPC patients in the post-docetaxel setting than AA.
