POU6F2 mutation in humans with pubertal failure alters GnRH transcript expression.

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by the absence of pubertal development and subsequent impaired fertility often due to gonadotropin-releasing hormone (GnRH) deficits. Exome sequencing of two independent cohorts of IHH patients identified 12 rare missense variants in POU6F2 in 15 patients. POU6F2 encodes two distinct isoforms. In the adult mouse, expression of both isoform1 and isoform2 was detected in the brain, pituitary, and gonads. However, only isoform1 was detected in mouse primary GnRH cells and three immortalized GnRH cell lines, two mouse and one human. To date, the function of isoform2 has been verified as a transcription factor, while the function of isoform1 has been unknown. In the present report, bioinformatics and cell assays on a human-derived GnRH cell line reveal a novel function for isoform1, demonstrating it can act as a transcriptional regulator, decreasing GNRH1 expression. In addition, the impact of the two most prevalent POU6F2 variants, identified in five IHH patients, that were located at/or close to the DNA-binding domain was examined. Notably, one of these mutations prevented the repression of GnRH transcripts by isoform1. Normally, GnRH transcription increases as GnRH cells mature as they near migrate into the brain. Augmentation earlier during development can disrupt normal GnRH cell migration, consistent with some POU6F2 variants contributing to the IHH pathogenesis.

Mental status and physical activity in patients with homozygous familial hypercholesterolemia: A subgroup analysis of a nationwide survey (A-HIT1 registry).

BACKGROUND: Homozygous familial hypercholesterolemia (HoFH) is a rare, life-threatening disease due to high serum low-density lipoprotein (LDL) cholesterol levels. LDL cholesterol-lowering interventions are fundamental for patients with HoFH. OBJECTIVE: It was aimed to investigate the association between the mental status of patients with HoFH and healthy lifestyle behaviors. METHODS: This subgroup analysis of the A-HIT1 population included the data of patients aged ≥18 years with a clinical diagnosis of HoFH undergoing therapeutic LDL apheresis. Besides the demographic and clinical characteristics of patients, healthy lifestyle behaviors were assessed, and psychiatric symptoms were screened by Symptom Check List (SCL-90-R). RESULTS: The highest percentage for pathology was observed in dimensions of obsessive-compulsive, somatization, interpersonal sensitivity, and depression in SCL-90-R. Patients with any cardiovascular condition have more psychiatric symptoms in different fields of SCL-90-R. The outcomes of the correlative analysis indicated that lower the age of the first coronary event better the psychiatric status, probably denoting a better adaptation to disease and its treatment. Among 68 patients, 36 patients were not exercising regularly. Patients with regular physical activity had significantly lower scores in most dimensions of SCL-90-R and there was no association between regular physical activity and other investigated variables. The strongest predictor of regular exercising was global severity index of SCL-90-R. CONCLUSION: In the HoFH population, there was a high prevalence of mental disturbances. Better psychiatric status was associated with regular exercising. Therefore, assessing the mental status of patients with HoFH and referring patients in need, to a psychiatrist, may improve the outcome of patients.

Clinical management, psychosocial characteristics, and quality of life in patients with homozygous familial hypercholesterolemia undergoing LDL-apheresis in Turkey: Results of a nationwide survey (A-HIT1 registry).

BACKGROUND: Homozygous familial hypercholesterolemia (HoFH) is a rare, life-threatening inherited disease leading to early-onset atherosclerosis and associated morbidity. Because of its rarity, longitudinal data on the management of HoFH in the real world are lacking, particularly on the impact the condition has on quality of life (QoL), including the impact of the extracorporeal lipid removal procedure apheresis (LA). METHODS: The A-HIT1 study included 88 patients with HoFH aged ≥12 years receiving regular LA in 19 centers in Turkey. Demographic and disease characteristics data were obtained. For patients aged ≥18 years, additional data on psychosocial status were obtained via the SF-36 score, the Hospital Anxiety and Depression Scale, and a HoFH-specific questionnaire. RESULTS: There was no standardized approach to therapy between centers. Mean (±SD) frequency of LA sessions was every 19.9 (±14) days, with only 11.6% receiving LA weekly, and 85% of patients were not willing to increase LA frequency. The most common concerns of patients were disease prognosis (31%), and physical, aesthetic, and psychological problems (27.5%, 15.9%, and 11.6%, respectively). Lower age at diagnosis was associated with better QoL, lower anxiety, improved functioning, and greater emotional well-being compared to later diagnosis. CONCLUSIONS: These findings demonstrate that adult patients with HoFH undergoing LA, experience significant impairment of QoL with an increased risk of depression. From patients' point of view, LA is time-consuming, uncomfortable, and difficult to cope with. The speed of diagnosis and referral has a considerable impact on patient well-being.

What have we learned from Turkish familial hypercholesterolemia registries (A-HIT1 and A-HIT2)?

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common genetic disease of high-level cholesterol leading to premature atherosclerosis. One of the key aspects to overcome FH burden is the generation of large-scale reliable data in terms of registries. This manuscript underlines the important results of nation-wide Turkish FH registries (A-HIT1 and A-HIT2). METHODS: A-HIT1 is a survey of homozygous FH patients undergoing low density lipoprotein (LDL) apheresis (LA). A-HIT2 is a registry of adult FH patients (homozygous and heterozygous) admitted to outpatient clinics. Both registries used clinical diagnosis of FH. RESULTS: A-HIT1 evaluated 88 patients (27 ±â€¯11 years, 41 women) in 19 centers. All patients were receiving regular LA. There was a 7.37 ±â€¯7.1-year delay between diagnosis and initiation of LA. LDL-cholesterol levels reached the target only in 5 cases. Mean frequency of apheresis sessions was 19 ±â€¯13 days. None of the centers had a standardized approach for LA. Mean frequency of apheresis sessions was every 19 ±â€¯13 (7-90) days. Only 2 centers were aware of the target LDL levels. A-HIT2 enrolled 1071 FH patients (53 ±â€¯8 years, 606 women) from 31 outpatients clinics specialized in cardiology (27), internal medicine (1), and endocrinology (3); 96.4% were heterozygous. 459 patients were on statin treatment. LDL targets were attained in 23 patients (2.1% of the whole population, 5% receiving statin) on treatment. However, 66% of statin-receiving patients were on intense doses of statins. Awareness of FH was 9.5% in the whole patient population. CONCLUSIONS: The first nationwide FH registries revealed that FH is still undertreated even in specialized centers in Turkey. Additional effective treatment regiments are urgently needed.

A nation-wide survey of patients with homozygous familial hypercholesterolemia phenotype undergoing LDL-apheresis in Turkey (A-HIT 1 registry).

BACKGROUND AND AIMS: Homozygous familial hypercholesterolemia (HoFH) is a genetic condition characterized by lethally high levels of low-density lipoprotein cholesterol (LDL-C) from birth, and requires rapid and aggressive intervention to prevent death due to coronary heart disease and/or atherosclerosis. Where available, lipoprotein apheresis (LA) is the mainstay of treatment to promote survival. METHODS: A-HIT1 registry was conducted with the aim of providing insight to the real-life management of HoFH patients undergoing LA in Turkey, where LA procedures are fully reimbursed and widely available. Participating centers provided patient information, including family history, treatment patterns and relevant laboratory values, via a standard questionnaire. RESULTS: The study evaluated 88 patients (mean age: 27 ±â€¯11 years, 41 women) in 19 centers. All patients were receiving regular LA with a clinical diagnosis of HoFH. Mean age at first symptom disease was 10 ±â€¯10 years, and at diagnosis it was 12 ±â€¯11 years; 74.7% were diagnosed before age 15 years; and only 31% before the age of 7. First referral of most patients was to pediatricians. Early onset coronary artery disease was present in 57.8% of patients. Mean age at first LA was 21 ±â€¯12 years. Only 11 (12.5%) patients were undergoing LA weekly. Mean frequency of apheresis sessions was 19 ±â€¯13 days. For the last four LA sessions, LDL-C levels reached the target in only in 5.7% of patients. CONCLUSIONS: Diagnosis of HoFH is delayed, and LDL targets are not reached. LA frequencies are not optimal. Urgent attention is needed to support the survival of patients with HoFH.

The association between methylation levels of targeted genes and albuminuria in patients with early diabetic kidney disease.

OBJECTIVE: The incidence of diabetes and its complications are greatly increasing world-wide. Diabeticnephropathy (DN) is the main cause of end-stage renal disease and is associated with high morbidity and mortality. It is important to predict patients with high risk for DN in the early stage. We selected the genes which have an important role on diabetic kidney disease. We aimed to investigate the association between DNA methylation levels of targeted genes and albuminuria in patients with early DN. METHODS: We collected the clinical data of patients with type 2 diabetes mellitus. We measured spot urine albumin creatinine ratio to calculate albuminuria level. We divided patients into two groups based on albumin excretion as patients with (n = 69) and without DN (n = 27). We performed methylation profiling after bisulfite conversion by pyrosequencing method. The mean value of percent methylation level of each gene was calculated. RESULTS: We compared targeted genes (TIMP-2, AKR1B1, MMP-2, MMP-9, MYL9, SCL2A4, SCL2A1, SCL4A3) methylation levels and albuminuria. We found significant negative correlation between TIMP-2 and AKR1B1 gene methylation levels and albuminuria levels. CONCLUSIONS: The present study provided evidence that hypomethylation of TIMP-2 and AKR1B1 genes can be associated with albuminuria in patients with early DN. We may speculate that the hypomethylation of TIMP-2 and AKR1B1 genes may be an early surrogate marker of DN.

The relationship between phthalates and obesity: serum and urine concentrations of phthalates.

BACKGROUND: A limited number of human and animal studies suggest that a relationship exists between phthalates and obesity, although this is not supported by all research. The purpose of this study was to investigate the relationship between Body Mass Index (BMI) and the levels of phthalates in human blood and urine samples. METHODS: Sixty-four overweight or 132 obese individuals (total=196) of different ages (min-max, 17-62; mean ± SD, 42.07±11.3) and genders (F:M 97:99) enrolled in the study. BMI and waist circumference were measured to diagnose obesity. Venous blood samples were taken after overnight fasting. To compare the urine phthalates among participants, single spot urine (at least 10 mL) was collected from the subject after blood samples were taken. Urine and blood phthalate concentrations were measured using gas chromatography. RESULTS: Total blood/urinary phthalate levels significantly increased in proportion to the degree of obesity. There was a high correlation between the level of total phthalates in serum and BMI (ρ=0.697, P<0.001), and between total urinary phthalate levels and BMI (ρ=0.707, P<0.001). CONCLUSIONS: This is the first study to have shown that both blood and urinary phthalates increased in proportion to BMI. The results show a strong association between obesity and phthalates.

Calcium Homeostasis During Attack and Remission in Patients With Idiopathic Benign Paroxysmal Positional Vertigo.

OBJECTIVE: To evaluate changes in calcium metabolism in patients with idiopathic benign paroxysmal positional vertigo (BPPV) on initial presentation and at the follow-up visit. SUBJECTS AND METHODS: The study comprised a total of 31 patients aged greater than 18 years who presented at the otorhinolaryngology outpatient clinic of our hospital, newly diagnosed as idiopathic BPPV based on the history compatible with BPPV and positive provocative maneuver (either Dix-Hallpike or Roll test). The first blood sample was obtained on the day of initial presentation when the patient was found to have active unilateral BPPV. After 6 months, a blood sample was again drawn in accordance with the procedure. Blood samples were analyzed for data on 25-hydroxyvitamin D (25(OH)-D), total calcium, parathormone and ionized calcium on initial presentation, and at the follow-up visit. RESULTS: The patients comprised 20 (64.5%) women and 11 (35.5%) men with a mean age of 49.78 years (range, 23-75 years). During an attack a higher prevalence of decreased serum Vitamin D is less than 20 ng/ml, was determined (93.5% versus 38.7%). There were statistical differences between the Vitamin D values, parathormone, and corrected by pH ionized calcium in both periods (p < 0.05). CONCLUSION: A statistically significant association was determined between Vitamin D and calcium metabolism in patients with idiopathic BPPV. It can be considered that Vitamin D deficiency and decreased ionized Ca level may be a risk for BPPV, not only in patients with osteoporosis but also in all patients. Very low levels of 25(OH)-D seem to be associated with recurrence of BPPV. The recurrences might possibly be prevented with supplementary Vitamin D especially in those with recurrent idiopathic BPPV but further studies would be necessary to determine this.

Higher Serum Bisphenol A Levels in Diabetic Hemodialysis Patients.

BACKGROUND: Bisphenol A (BPA) has been implicated as an 'endocrine disruptor'. We aimed at exploring the association between serum BPA levels and patient characteristics, particularly the presence of diabetes mellitus, and laboratory parameters in hemodialysis patients. METHODS: This study included 47 chronic hemodialysis patients. Patient characteristics were recorded. Blood was drawn before and after hemodialysis session. Serum BPA levels were measured by the high-performance-liquid-chromatography and laboratory parameters were measured by using standard methods. RESULTS: In hemodialysis patients, postdialysis serum BPA levels were significantly higher than predialysis after a single hemodialysis session (5.57 ± 1.2 vs. 4.06 ± 0.73, p < 0.0001). Predialysis serum BPA levels were significantly higher in patients with diabetes than non-diabetics (4.4 ± 0.6 vs. 3.9 ± 0.7, p = 0.025). No association was found between serum BPA levels and patient characteristics, and particularly laboratory parameters. CONCLUSION: Serum BPA levels were rising significantly after a single dialysis session. Diabetic hemodialysis patients had higher predialysis serum BPA levels.

The Presence of Demodex Folliculorum in Various Obese Groups According to BMI Levels.

BACKGROUND: This study aimed to detect the presence of the parasite Demodex folliculorum (DF) in various obese groups according to BMI Levels. MATERIALS AND METHODS: A total of 182 patients (40.8 ± 14.8 years, min-max age 19 - 73 years) were enrolled in the study, of those 65 (35.7%) were female and 117 (64.3%) were male. They had previously applied to Mustafa Kemal University (Faculty of Medicine, Endocrine Outpatient Clinic) during 2012. A standardized skin surface biopsy method was used to research the existence of DF. Patients were classified into four main groups, including: obese (n = 89), overweight (n = 31), normal (n = 32), and underweight (n = 30). RESULTS: There was no significant difference between groups in terms of age and sex. The total DF positivity was 19 (21.3%) in obese patients. Among those with positive DF, the mean BMI was 35.7 ± 12.1 kg/m(2), while those with negative DF had a mean BMI of 29.2 ± 9.2 kg/m(2). There was a significant difference between two groups (P = 0.002). Also, the underweight group has significantly higher DF positivity in comparison to the normal weight group. CONCLUSION: The DF positivity was significantly higher in obese patients in accordance with the physiopathologic nature of the disease.

Mortal quintet of sickle cell diseases.

BACKGROUND: Sickle cell diseases (SCDs) are chronic inflammatory processes on capillary level. We tried to understand some possible correlations between stroke and severity of SCDs. METHODS: All patients with SCDs were taken into the study. RESULTS: The study included 343 patients (174 males and 169 females). There were 30 cases (8.7%) with stroke. The mean ages were similar in both groups (32.5 versus 29.1 years in the stroke group and other, respectively, P>0.05). The female ratios were similar in both groups, too (43.3% versus 49.8%, respectively, P>0.05). Prevalences of associated thalassemia minors were also similar in them (73.3% versus 65.1%, respectively, P>0.05). Smoking was higher among the stroke cases, significantly (26.6% versus 13.0%, P<0.05). Mean white blood cell count, hematocrit value, and mean platelet count of the peripheric blood were similar in both groups (P>0.05 for all). On the other hand, although the painful crises per year, tonsilectomy, priapism, ileus, pulmonary hypertension, chronic obstructive pulmonary disease, coronary heart disease, chronic renal disease, rheumatic heart disease, avascular necrosis of bones, cirrhosis, and mortality were all higher in the stroke group, the differences were only significant for acute chest syndrome (ACS), digital clubbing, and leg ulcers (P<0.05 for all), probably due to the small sample size of the stroke group. CONCLUSION: SCDs and smoking are chronic destructive processes on endothelium, and both terminate with early organ failures in life. Probably smoking, digital clubbing, leg ulcers, ACS, and stroke are mortal quintet of the SCDs that may indicate shortened survival in such patients.

Tonsilectomy in sickle cell diseases.

BACKGROUND: We tried to understand whether or not there are lowered prevalences of terminal consequences of sickle cell diseases (SCDs) with tonsilectomy. METHODS: All cases with SCDs were taken into the study. RESULTS: The study included 334 patients (164 females). There were 27 cases with tonsilectomy and 307 cases without. The mean ages, female ratios, and prevalences of associated thalassemia minors and smoking were similar in both groups (P>0.05 for all). Although the white blood cell and platelet counts of peripheric blood were higher in patients without tonsilectomy, the mean hematocrit value was lower in them, but the differences were nonsignificant probably due to the small sample size of the tonsilectomy group (P>0.05 for all). Similarly, although the painful crises per year, digital clubbing, leg ulcers, pulmonary hypertension, chronic obstructive pulmonary disease, rheumatic heart disease, avascular necrosis of bone, cirrhosis, stroke, and mortality were higher in cases without tonsilectomy, the differences were nonsignificant probably due to the same reason again (P>0.05 for all). CONCLUSION: There may be an inverse relationship between prevalence of tonsilectomy and severity of SCDs, and the tonsils may act as chronic inflammatory foci accelerating the chronic endothelial damage all over the body in such patients.

Migrated phthalate levels into edible oils.

The determination of phthalates in edible oils (virgin olive oil, olive oil, canola oil, hazelnut oil, sunflower oil, corn oil) sold in Turkish markets was carried out using gas chromatography-mass spectrometry. Mean phthalate concentrations were between 0.102 and 3.863 mg L(-1) in virgin olive oil; 0.172 and 6.486 mg L(-1) in olive oil; 0.501 and 3.651 mg L(-1) in hazelnut oil; 0.457 and 3.415 mg L(-1) in canola oil; 2.227 and 6.673 mg L(-1) in sunflower oil; and 1.585 and 6.248 mg L(-1) in corn oil. Furthermore, the influence of the types of oil and container to the phthalate migration was investigated. The highest phthalate levels were measured in sunflower oil. The lowest phthalate levels were determined in virgin olive oil and hazelnut oil. The highest phthalate levels were determined in oil samples contained in polyethylene terephthalate.

Does polycystic ovary syndrome itself have additional effect on apelin levels?

Objective. The present study was designed to compare serum levels of apelin between lean PCOS women and healthy women with regular menses. Study Design. A total of 30 lean patients with PCOS and 30 healthy subjects were included in this study. Serum apelin levels were compared between groups. Results. Serum apelin levels in lean PCOS patients were not significantly different from the control subjects. Conclusion. Our findings indicate that PCOS itself does not seem to change apelin levels. Further investigation on a large number of subjects will need to be conducted to prove the consistent or variable association in PCOS.

Investigation of vitamin D levels in patients with vitiligo vulgaris.

The aim of the study was to investigate serum 25-hydroxyvitamin D (25(OH) D3) levels in patients with vitiligo vulgaris in terms of causal relation and extension of the disorder. This study is a clinical cross-sectional study carried out in order to determine 25-hydroxyvitamin D levels among 25 patients with vitiligo vulgaris and in 41 controls. Fitzpatrick skin phototypes, history of autoimmune disease, family history of vitiligo, and duration of the disease were also evaluated. The mean levels of vitamin D in patient and the control group were 15.2±5.2 ng/dL and 14.4±6.2 ng/dL respectively (P>0.05). In our study, 48% of the patients had insufficient (<30 ng/mL) and 52% had very low (<15 ng/mL) levels of vitamin D. There was no correlation between age, duration of the disease, and body surface area affected with vitamin D levels. There was no significant difference in vitamin D levels between patients who had family history of vitiligo (5 patients, 20%) and those that did not. Vitamin D levels were found to be insufficient (<30 ng/mL) or very low (<15 ng/mL) in most of the patients with vitiligo vulgaris, but not statistically significantly different as a group when compared to the controls. More studies are needed to differentiate between the effects of low vitamin D levels on pathogenesis of vitiligo vulgaris and lower vitamin D levels as a result of the disease.

Diabetic foot due to anaphylactic shock: a case report.

INTRODUCTION: Diabetic foot is a clinical disorder, which is commonly seen in patients with diabetes mellitus. It is also the major cause of below knee amputation in the world. There are many underlying causes such as neuropathic, ischemic, and infectious causes for diabetic foot. Local or systemic complications may develop after snake bite. CASE PRESENTATION: We reported a very rare case, involving a 78-year-old male admitted to the Emergency Department, who developed anaphylactic shock and diabetic foot after the snake bite. CONCLUSIONS: Reviewing the literature, this is the second reported case of snake bite associated with diabetic foot.

Evaluation of mean platelet volume in patients with type 2 diabetes mellitus and blood glucose regulation: a marker for atherosclerosis?

OBJECTIVE: Platelets have an important role in atherosclerosis and arterial thrombosis. Cardiovascular complication prevalence of type 2 diabetes mellitus (type 2 DM) may be associated with glycosylated hemoglobin (HbA1c) and mean platelet volume (MPV). The aim of the study was to investigate if platelets were activated in diabetes and its associated vascular complications by measuring the MPV in the diabetics compared to the non-diabetics, and to determine the correlation of MPV with fasting serum glucose (FSG), HbA1c and duration of diabetes in the diabetic patients, respectively. MATERIALS AND METHODS: The study carried out in 65 patients with type 2 DM and 40 non-diabetic subjects. In addition to non-diabetic patients, all diabetic patients were divided into two groups according to their HbA1c levels: group A consisted of patients with HbA1c levels ≤7% and group B consisted of patients with HbA1c levels >7%. RESULTS: MPV was significantly higher in Group B as compared to both non-diabetics and Group A. MPV had a high positive correlation with HbA1c and FSG, as with diabetes duration. It is found that MPV was increased in type 2 DM. CONCLUSION: Our findings suggested an association between MPV and HbA1c. Therefore, MPV would be a beneficial prognostic marker of cardio-vascular complications in patients with type 2 DM.

Comparison of the chronic effects of ribavirin and caffeic acid phenethyl ester (CAPE) on pancreatic damage and hepatotoxicity.

UNLABELLED: This study was aimed to comparison of the effects of the chronic use of the Ribavirin and caffeic acid phenethyl ester (CAPE) on the pancreatic damage and hepatotoxicity in rats. METHODS: The rats were given orally 30 mg/kg/day doses of Ribavirin for 30 days, and intraperitoneally 10 µmol/kg doses of CAPE. The 37 rats were divided into 4 groups: (I) Control (n=7), (II) Ribavirin (R) (n=10), (III) CAPE (n=10), and (IV) R+CAPE (n=10). RESULTS: Ribavirin and CAPE yielded similar results in terms of Serum, total antioxidant status (TAS), total oxidant status (TOS), amylase, lipase, and insulin compared to the control group. However, while Ribavirin provided similar results with the control group in terms of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes, the CAPE group had elevated AST and ALT levels compared to the control group. Histopathologic evaluations revealed that CAPE or Ribavirin had no degenerative effects on both the pancreas and liver tissues. In this way, the biochemical results were confirmed by the histopathologic results. CONCLUSION: It can be concluded that Ribavirin does not lead to any pancreatic damage and hepatotoxicity, and has more beneficial effects than CAPE on especially liver tissue.

Low serum levels of vitamin D in metastatic cancer patients: a case-control study.

Accompanying comorbidities observed during the cancer treatment usually affect the course and outcome of the therapy. Hypovitaminosis D, which is one of these conditions, is a resolvable problem, if recognized. In this study, we investigated whether the serum 25(OH)D levels of the patients who were presented to our outpatient clinic were different from the serum levels of the healthy population living in the same area. Our study included 90 patients who were presented to the Medical Oncology outpatient clinic and 90 age, gender, body mass index and ethnic origin matched controls without a known disease, who were presented to the outpatient clinics of the Departments of Internal Diseases and Family Medicine for routine controls. Blood count tests, detailed biochemistry tests (including serum levels of Cr, Ca and P), measurement of serum 25(OH)D levels and C-reactive protein were performed in serum samples of all of the patients and controls. Mean serum levels of 25(OH)D were 13.5 ng/ml (SD 5.1) in all cancer patients, 13.1 ng/ml (SD 4.2) in the patients who were presented for adjuvant therapy, 13.8 ng/ml (SD 5.5) in the patients who were presented at metastatic stage and 18.4 ng/ml (SD 12.5) in the controls. Mean serum CRP levels were 5.4 mg/dl (SD 1.2) in the control group, 8.4 mg/dl (SD 4.3) in the adjuvant therapy group and 20.3 (SD 16.8) in the patients with metastatic disease. Generally, all cancer patients (p 0.003) and the patients with metastatic cancer (p 0.004) had lower serum 25(OH)D levels compared to controls, and there was an inverse correlation between serum 25(OH)D and CRP levels in patients with metastatic cancer (p 0.036). In metastatic cancer patients, hypovitaminosis D may be a comorbidity and it is recommended to consider during initial evaluation and follow-up. Because it might improve these patients quality of life and chemotherapy adherence.

Investigation of neutrophil lymphocyte ratio and blood glucose regulation in patients with type 2 diabetes mellitus.

OBJECTIVE: Leukocytosis is thought to be directly associated with the pathogenesis of atherosclerosis and metabolic syndrome. Increased white blood cell (WBC) count is related to cardiovascular disease in patients with type 2 diabetes mellitus; raised neutrophil lymphocyte ratio (NLR) is associated with metabolic syndrome. There is little information, however, concerning a correlation between glycosylated haemoglobin (HbA1c) and NLR. The aim of the present study was to investigate the relationship between NLR and blood glucose regulation. METHODS: This retrospective study was conducted in patients with type 2 diabetes mellitus, divided into two groups according to HbA1c levels: group 1, HbA1c levels ≤ 7%; group 2, HbA1c levels > 7%. Venous WBC, neutrophil and lymphocyte counts were determined. RESULTS: Of 71 patients included, fasting serum glucose, neutrophil and WBC counts were significantly higher in group 2 compared with group 1. NLR had a positive correlation with HbA1c. CONCLUSION: There may be a significant relationship between NLR and blood glucose regulation. The authors propose that increased NLR may be associated with elevated HbA1c in patients with type 2 diabetes mellitus.
