Vitamin D and inflammation: evaluation with neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio.

INTRODUCTION: Association of vitamin D, inflammation and endothelial dysfunction, beside the classic bone metabolism disorders, may explain the pathogenesis of numerous diseases associated with vitamin D deficiency. While large numbers of reports support the relationship of vitamin D with inflammation, several reports fail to confirm this relationship. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are novel and inexpensive markers of inflammation that can be studied in all centers. The goal of this study was to investigate the association between 25-hydroxy vitamin D (25(OH)D) and inflammation with the novel inflammatory markers NLR and PLR. MATERIAL AND METHODS: This study was performed retrospectively. Results of the simultaneously performed 25(OH)D, parathyroid hormone, albumin, calcium, phosphorus, alkaline phosphatase and creatinine level measurements and complete blood count were recorded. The data of 4120 patients were included in the study. RESULTS: Between vitamin D deficient and non-deficient groups there were significant differences in PLR (p < 0.001) and NLR (p = 0.001). Vitamin D had a significant negative correlation with PLR (p < 0.001) and NLR (p < 0.001). Multiple regression analysis indicated that 25(OH)D was independently and negatively correlated with PLR (OR = 0.994, 95% CI 0.991-0.998, p = 0.02). CONCLUSIONS: Platelet-to-lymphocyte ratio and NLR were significantly associated with 25(OH)D levels, and PLR was found to be an independent predictor of 25(OH)D levels. Our study revealed an inverse association of vitamin D levels and inflammation with these inexpensive and universally available markers.

Primary hyperparathyroidism in pregnancy: a case series and literature review.

Primary Hyperparathyroidism (PHP) in pregnancy constitutes a serious danger to mother and fetus. The diagnosis of PHP in pregnancy presents a challenge, and PHP commonly goes unidentified and untreated in pregnancy. We present four case reports about patients having PHP, which is very rare condition in pregnancy and their treatment modalities. Three patients, not to be controlled biochemically, denied the parathyroidectomy operation although they are informed about the details of their disease. They are followed up with medical therapy. The first one had no maternal or fetal complications, the second one acquired nephrolithiasis crisis in the last trimester and the third one gave birth to a premature baby who succumbed to tetany. The fourth patient who underwent parathyroidectomy operation in the second trimester had no maternal or fetal complications. PHP in pregnancy is a preventable cause of fetal and maternal mortality and morbidity. Thus, suspecting from PHP during the pregnancy and early diagnosis is critically important in terms of maternal and fetal wellness.

Natural History of Congenital Generalized Lipodystrophy: A Nationwide Study From Turkey.

CONTEXT: Congenital generalized lipodystrophy (CGL) is a rare autosomal recessive disorder characterized by near-total lack of body fat. OBJECTIVE: We aimed to study natural history and disease burden of various subtypes of CGL. DESIGN: We attempted to ascertain nearly all patients with CGL in Turkey. SETTING: This was a nationwide study. PATIENTS OR OTHER PARTICIPANTS: Participants included 33 patients (22 families) with CGL and 30 healthy controls. MAIN OUTCOME MEASURE(S): We wanted to ascertain genotypes by sequencing of the known genes. Whole-body magnetic resonance imaging was used to investigate the extent of fat loss. Metabolic abnormalities and end-organ complications were measured on prospective follow-up. RESULTS: Analysis of the AGPAT2 gene revealed four previously reported and four novel mutations (CGL1; c.144C>A, c.667_705delinsCTGCG, c.268delC, and c.316+1G>T). Analysis of the BSCL2 gene revealed four different homozygous and one compound heterozygous possible disease-causing mutations (CGL2), including four novel mutations (c.280C>T, c.631delG, c.62A>T, and c.465-468delGACT). Two homozygous PTRF mutations (c.481-482insGTGA and c.259C>T) were identified (CGL4). Patients with CGL1 had preservation of adipose tissue in the palms, soles, scalp, and orbital region, and had relatively lower serum adiponectin levels as compared to CGL2 patients. CGL4 patients had myopathy and other distinct clinical features. All patients developed various metabolic abnormalities associated with insulin resistance. Hepatic involvement was more severe in CGL2. End-organ complications were observed at young ages. Two patients died at age 62 years from cardiovascular events. CONCLUSIONS: CGL patients from Turkey had both previously reported and novel mutations of the AGPAT2, BSCL2, and PTRF genes. Our study highlights the early onset of severe metabolic abnormalities and increased risk of end-organ complications in patients with CGL.

Levels of endothelial cell-specific molecule-1 (ESM-1) in overt hypothyroidisim.

PURPOSE: Endothelial cell-specific molecule-1, endocan, is a proteoglycan that is expressed by the vascular endothelium. Endocan can be a biomarker of endothelial dysfunction caused by endothelial cell-dependent disorders. Endothelial dysfunction is an early step of atherosclerosis and is developed in hypothyroid patients, which indicates an association between hypothyroidism and atherosclerosis. Therefore, we aimed to investigate whether circulating endocan levels are associated with endothelial dysfunction in overt hypothyroid patients. MATERIALS AND METHODS: Forty patients with hypothyroidism diagnosed in the last 5 years and 30 healthy subjects were recruited. RESULTS: The mean endocan value in all patients was 0.63 ± 0.26 pg/ml, which was higher than that in controls (0.36 ± 0.10 pg/ml, p < 0.05). When we subgrouped the patients as hypothyroid and euthyroid, all groups demonstrated significantly different endocan levels, and hypothyroid patients had the highest endocan levels. A correlation analysis demonstrated that endocan levels were positively correlated with body mass index (BMI), thyroid-stimulating hormone (TSH), anti-thyroid peroxidase, and anti-thyroglobulin and negatively correlated with free thyroid hormone 4 (FT4) and vitamin D levels. In addition, in the patient group, endocan levels were correlated with FT4 levels independently in a covariance analysis. CONCLUSIONS: The circulating endocan level increased in hypothyroid patients, suggesting that endocan levels may be an early biomarker of the development of endothelial dysfunction in patients with hypothyroidism. They may also prove useful in the prediction of cardiovascular diseases after further studies using cardiovascular disease biomarkers. In addition, targeting endocan levels to decrease cardiovascular risk may be a new treatment strategy in these patients.

Salivary IL-6 and IL-10 levels in subjects with obesity and gingivitis.

PURPOSE: To evaluate the association between cytokines IL-6 and IL-10 in saliva, obesity and periodontal disease. METHODS: The study was carried out in 40 subjects: 20 obese subjects with gingivitis and 20 non-obese subjects with gingivitis (controls). Periodontal parameters such as gingival index (GI) and plaque index (PI) of subjects were recorded. Saliva samples were used for measuring IL-6 and IL-10 levels by ELISA method. RESULTS: Saliva IL-6 levels were significantly higher in obese subjects than those of non-obese subjects (P= 0.002). When total groups were evaluated, negative significant correlation between GI and salivary IL-10 levels (r= -0.452, P= 0.003) and positive correlations between salivary IL-6 level and body mass index (BMI) (r= 0.369, P= 0.019) were found. There was a negative correlation between the GI and salivary IL-10 levels in obese subjects (r= -0.548, P= 0.012). Also there was a positive correlation between the salivary level of IL-6 and IL-10 in obese subjects (r= 0.594, P= 0.006). CLINICAL SIGNIFICANCE: Obesity and adipose tissues can affect periodontal health by altering the levels of IL-6 and IL-10. IL-6 in saliva clearly increased in subjects with obesity compared to subjects without obesity. Also negative correlations between saliva IL-10 levels and GI were found in the total group and obese subjects.

Retinal Nerve Fiber Layer Thickness in Early-Stage Diabetic Retinopathy With Vitamin D Deficiency.

PURPOSE: To evaluate retinal nerve fiber layer (RNFL) thickness in early-stage diabetic retinopathy (DR) patients with and without vitamin D deficiency (VDD). METHODS: This study compared 50 early-stage DR patients with VDD (group 1) and 50 early-stage DR patients without VDD (group 2). All patients were examined by the same ophthalmologist. Mean RNFL thickness was determined by optical coherence tomography (OCT) performed by the two independent ophthalmologists for all subjects. Vitamin D levels were measured by using a radioimmunoassay. Vitamin D deficiency was defined, in accordance with the general standards, as a 25-hydroxyvitamin D (25(OH)D) level lower than 20 ng/mL. RESULTS: There were no significant differences between the groups in terms of age and sex distribution (P > 0.05). The mean serum 25(OH)D concentration of group 1 was significantly lower than that of group 2 (P < 0.001). The mean RNFL thickness of group 1 was significantly reduced compared to that of group 2 (P < 0.001). A significant relationship between the mean RNFL thickness and serum 25(OH)D concentrations was observed in group 1 (P < 0.001). CONCLUSIONS: The results indicate that vitamin D functions as a neuroprotective component for optic nerves. Low serum 25(OH)D concentrations contribute to RNLF thinning in early-stage DR patients with VDD.

Schwannomatozis of the Chest Wall: FDG PET Findings.

Authors present a rare case of bifocal schwannoma of thoracic wall showing metabolic activity on FDG PET images. A 43-year-old male with palpable mass on lateral chest wall was referred for F-18 FDG PET/CT imaging for differential diagnosis. His medical history and basic laboratory results were unremarkable. PET/CT images revealed a mild FDG uptake in the solid soft tissue mass in the left lateral chest wall that was growing outside of the thorax. It was located in 7th intercostal space and adjacent ribs were intact. Incidentally, second mass lesion was detected in the right posterior seventh intercostal space protruding to the pleural space and showing higher FDG uptake on PET/CT images. The lesions were surgically removed at the same session for definite diagnosis and treatment. Histopathologic evaluation of both lesions revealed benign schwannoma.

Spectrum and prevalence of nodular thyroid diseases detected by ultrasonography in the Western Black Sea region of Turkey.

OBJECTIVE: The aim of the study was to investigate thyroid diseases and the prevalence of goiter by ultrasonography (US) in a moderately iodine deficient area. MATERIAL-METHODS: The MELEN Study is a prospective cohort study on the prevalence of thyroid diseases in Turkish adults. A total of 2233 subjects with a mean age of 50 (age range 18 to 92) were submitted to study. Thyroid US was performed and interpreted by the same experienced physician. Goiter prevalence was defined according to Gutekunst's criteria. RESULTS: The most common thyroid disease was multinodular goiter (MNG) (42%), followed by nodular goiter (NG) (14.6%). The crude prevalence of nodular disease in the region was 56.6%. In the study cohort, thyrotoxicosis (TSH <0.35 µIU/ml) prevalence was 12 % and subclinical and overt hypothyroidism (TSH > 4.5 µIU/ml) prevalence was 6.5 %. CONCLUSION: We found that thyrotoxicosis and nodular thyroidal diseases are more important public health issues in moderate iodine deficient geographical areas. We recommend the increased rates of US screening especially in the endemic regions in order to detect thyroidal nodules earlier.

Association of uric acid, atherogenic index of plasma and albuminuria in diabetes mellitus.

BACKGROUND: The associations of serum uric acid (UA), atherogenic index of plasma (AIP) and albuminuria with cardiovascular disease have been shown. Several studies focused on association of serum UA and dyslipidemia, serum UA and renal impairment, dyslipidemia and renal impairment. However, to date, in literature, there have been no studies demonstrating the relationship between these parameters in diabetic patients together. AIMS: We aimed to investigate the association between serum UA, albuminuria and AIP in diabetic patients. METHODS: This was a retrospective study involving data of 645 diabetic patients. The patients were separated into groups according to their serum uric acid and AIP levels. The quantitative urine albumin/creatinine ratio in morning spot urine samples were used for standard albuminuria determination. Serum uric acid levels under 6 mg/dL were considered as normal. AIP was calculated as the logarithmically transformed ratio of triglyceride to high density lipoprotein cholesterol. RESULTS: AIP and albuminuria levels were high in high serum UA group compared to normal UA group. Uric acid and albuminuria tended to increase with increasing AIP. Correlation analysis showed that albuminuria, AIP and UA were significantly correlated with each other. Additionally, in binary logistic regression analysis, AIP was found to be independently associated with high UA levels. CONCLUSIONS: Present study reveals that serum UA, AIP and albuminuria are closely related. Physicians should be aware that patients with concomitant hyperuricemia, albuminuria and high AIP are at increased risk of developing cardiovascular disease. Our study confirms that there is a need for larger prospective studies to determine the mechanisms underlying the association of serum UA, AIP and albuminuria.

Unusually high prolactin level for medication-induced hyperprolactinemia: a case report.

Hyperprolactinemia has a number of etiologies, including physiological, pathological and pharmacological causes. Hyperprolactinemia is frequently associated with the use of certain medications. Patients using medications known to cause hyperprolactinemia generally develop a mild form of the condition, and the prolactin level rarely exceeds 100 ng/mL in these cases. We report a case of a 43-year-old woman with an extremely high prolactin level in medication-induced hyperprolactinemia caused by a combination of an antipsychotic (sulpirid) and an antidepressant (paroxetine).

Efficiency of radioactive I-131 therapy in geriatric patients with toxic nodular goiter.

BACKGROUND AND AIMS: The success of I-131 therapy in geriatric patients who were referred to an endocrinology clinic with toxic nodular goiter and who lived in iodine-deficiency regions was studied. MATERIALS AND METHODS: Patients older than 60 years who received I-131 therapy were included via retrospective data analyses. Fifty-nine patients between 60 and 82 years of age were enrolled in the study. The patients received an oral capsular form of I-131 (10-25 mCi) and were followed up for 1 year with clinical and laboratory results. Euthyroid or hypothyroid status at the end of the year after treatment was deemed to be a response to treatment. RESULTS: Of the 21 (36%) male and 38 (64%) female patients, 29 (49%) had a solitary toxic nodule and 30 (51%) had toxic multinodular goiter. Twenty-nine (49%) of the patients received propylthiouracil therapy. At the end of the year, 38 (64%) patients were euthyroid, 11 (19%) were hypothyroid, and 10 (17%) were thyrotoxic. Forty-nine (83%) patients who were euthyroid and hypothyroid were considered responders. CONCLUSION: Geriatric patients with toxic nodular goiter were shown to have a high response rate to I-131 therapy. Thus, we suggest that radioactive iodine treatment should be the first-line treatment in these patients.

[Normal value correlates of carotid intima- media thickness and affecting parameters in healthy adults]. / Saglikli eriskinlerde karotis intima-media kalinliginin normal degerleri ve etkileyen parametreler.

OBJECTIVE: Early changes in atherosclerosis can be diagnosed by the carotid artery intima-media thickness (CIMT) measurement. Normal range of CIMT in healthy subjects has not been studied yet in our country. Therefore, the aim of this study was to measure the CIMT in healthy individuals and investigate affecting parameters of CIMT. METHODS: Overall, 2298 subjects, aged 18 to 92 years were undergone CIMT measurement in this observational cohort study. 151 healthy adult subjects, aged 20 to 79 year without atherosclerotic risk factors, normal body mass index and normal metabolic parameters were selected to establish normative CIMT values. Correlations between CIMT and atherosclerotic risk factors were evaluated in the Turkish population. The independent variables associated with CIMT were evaluated with multiple linear regression analysis. RESULTS: CIMT value was 0.458 ± 0.116 mm in males and 0.47 ± 0.104 mm in females. Mean values of CIMT (in mm) for healthy reference sample aged 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 years were 0.402; 0.466; 0.492; 0.586; 0.692 and 0.733, respectively. CIMT increased significantly (p<0.001) by 0.066 mm, in every decade. Correlates of CIMT were age, visceral fat level, fasting serum glucose, total and low-density lipoprotein cholesterol. Multiple linear regression analysis revealed that age was the single independent predictor of CIMT thickness in healthy individuals (ß=0.007, 95% CI: 0.006-0.008, p<0.001). CONCLUSION: CIMT was 0.458 ± 0.116 mm in men and 0.47 ± 0.104 mm in Turkish healthy adults. Age was the only predictor of CIMT. CIMT measurement can be used in the assessment of early atherosclerosis burden in adults.

Cystatin C levels in patients with dipper and nondipper hypertension.

OBJECTIVE: Subjects with nondipper hypertension carry a higher risk of cardiovascular events than their normotensive counterparts. The present study was designed to investigate cystatin C levels in patients with dipper and nondipper hypertension. METHODS: Eighty-eight consecutive patients who had been treated with antihypertensive drugs for at least 6 months were included in the study. Dipping and nondipping patterns were detected with ambulatory blood pressure monitoring. Clinical, laboratory, and ambulatory blood pressure monitoring data of patient groups with nondipper and dipper hypertension were compared. RESULTS: Patients in the nondipper group were older than those in the dipper group. Serum cystatin C level was higher in the patients in the nondipper group. Cystatin C was negatively correlated with the rate of systolic blood pressure fall at night (r = -0.41; P < 0.001). Linear regression analyses revealed that only cystatin C level was a significant correlate of nocturnal systolic blood pressure decrease. Logistic regression analyses also showed that cystatin C was an independent predictor of nondipping pattern (odds ratio, 3.586; 95% confidence interval, 1.432-8.98; P = 0.006]). CONCLUSION: The present study showed that cystatin C is higher in patients with nondipper hypertension patients.

Benign localized fibrous tumor of the pleura: report of 25 new cases.

OBJECTIVE: Benign localized fibrous tumors (BLFT) of the pleura are very rare slow-growing neoplasms that generally have a favorable prognosis. The aim of this manuscript is to evaluate the predictors of outcome with the review of the literature in a series of 25 patients with BLFT. METHODS: Between January 1985 and November 2009, 25 patients underwent an operation due to BLFT. Of these patients, 14 (56%) were male; mean age was 41.1 (25 to 64) years. All patients underwent thoracotomy. Left thoracotomy approach was used in 16 patients. The mass lesions were totally excised. The histopathological examinations were performed with hematoxylin-eosin and immunohistochemical staining methods. RESULTS: Of the patients, 18 (72%) were symptomatic. Symptoms were cough in 36%, shortness of breath in 32%, and chest pain in 20% of the patients. One patient (4%) appeared to have some symptoms (pain and swelling of the joints) associated with pulmonary osteoarthropathy. Seven patients (28%) underwent an operation due to mass lesion detected at routine control visits. None of the patients had a history of exposure to asbestos. Radiological investigations revealed 16 (64%) mass lesions in the left. Of the lesions found on exploration, 5 (20%) were intrapulmonary localized lesion without pedicle and 20 were pedicled. Of the pedicled masses, 5 were connected to parietal pleura and 15 to visceral pleura and all were intrathoracic extrapulmonary localized lesions. Eight (32%) lesions connected to left lower lobe. Additionally, three pedicled lesions were located in the lung fissure. Pedicled lesions were totally excised together with their pedicles. Intraparenchymal mass lesions were resected using wedge resection. The diameter of the resected masses was ranging between 3 and 22 cm (mean: 8.7). Macroscopically, all were encapsulated with a homogeneous cut surface. Intraoperative mortality and morbidity was not observed. The average hospitalization duration for all patients was 8.6 days (5 to 12). The mean follow-up was 33.6 (9 to 142) months with no recurrence. CONCLUSIONS: Benign localized fibrous tumors are uncommon and treated by surgical means. According to our data obtained from literature review, clinicians should be aware of recurrence possibility even after complete resection of benign localized fibrous tumor and the risk of malign transformation.

Rheumatoid arthritis masquerading as acromegaly recurrence: report of two cases.

Acromegaly is a chronic endocrinopathy characterized by hypersecretion of growth hormone (GH) and consequently of insulin-like growth factor-1 (IGF-1). The arthropathy in acromegaly is the most frequent and important cause of morbidity and functional disability in acromegaly. Rheumatoid arthritis (RA) is a rarely reported clinical situation in patients with acromegalic. We herein report 57- and 45-year-old two women, who complained bilateral, symmetric pain, swelling and morning stiffness in the joints of hands after optimal acromegaly treatment resembling acromegaly arthropathy. There was not arthralgia in other joints of the patients. Laboratory and radiological evaluations were carried out. After excluding the acromegaly activation and arthropathy by GH and IGF-1 measurement, according to clinical presentation, laboratory and radiological assessments, patients were diagnosed as RA.

Association of mean platelet volume with DSM-IV major depression in a large community-based population: the MELEN study.

The relationship between major depression and increased platelet activity has been previously stated by several studies. This study sought to test the relationship between mean platelet volume (MPV)--an indicator of platelet activity--and major depression, in an adult Turkish population sample. Respondents were 2286 participants interviewed in a regional survey. The diagnosis of current (one month) major depression was made according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. MPV was measured along with total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, BMI, and waist circumference. Two hundred eighty-nine participants (12.5%) were diagnosed as having major depression. Patients with major depression were found to have increased MPV levels in comparison with participants without depression (p = 0.001). After excluding the subjects with risk factors capable of influencing platelet activity, MPV was still found to be elevated in patients with major depression compared with non-depressed individuals (p < 0.01). Linear regression analysis revealed a significant independent association of major depression with MPV levels (r = 0.123; p = 0.001). According to the findings of this study, increased MPV (or platelet activation) is associated with current (one month) diagnosis of major depression. Future research should investigate the effect of depression treatment on MPV.

Mean platelet volume in patients with non-alcoholic fatty liver disease.

Mean platelet volume (MPV) is an indicator of platelet activation. Platelet activation and aggregation are central processes in the pathophysiology of coronary heart disease. Non-alcoholic fatty liver disease (NAFLD) is present up to one-third of the general population and the majority of patients with cardio-metabolic risk factors such as abdominal obesity, type 2 diabetes and other components of the metabolic syndrome (MS). The aim of the current study was to investigate the MPV in patients who had NAFLD. MPV values of the patients with NAFLD and of the patients without fatty liver disease were compared. NAFLD patients had significantly higher body mass index compared to the control cases. Among biochemical variables, fasting plasma glucose and triglyceride were significantly higher in the NAFLD group. NAFLD cases also had lower platelet count and higher MPV (10.43 +/- 1.14 vs. 9.09 +/- 1.25; p < 0.001, respectively). MPV was positively correlated with AST (r: 0.186, p < 0.042), ALT level (r: 0.279; p 0.002) and the presence of NAFLD (0.492; p < 0.001) but negatively correlated with platelet number (r: -0.26; p 0.004) and creatinine (r: -0.255; p 0.005). In logistic regression analysis (age, gender, NAFLD, body mass index, high-density lipid (HDL) cholesterol, systolic and diastolic blood pressure, triglyceride and fasting plasma glucose were used as covariates) only NAFLD was found to be the independent predictor of MPV (Odds Ratio (OR) 21.98) [95% confidence interval (CI): 2.404-201.048; p: 0.006]. We have shown for the first time in the literature that, patients with NAFLD have higher MPV. It may have prognostic value in NAFLD patients indicating a possible cardiovascular disease (CVD) risk increase.
