Simple Markers for Subclinical Inflammation in Patients with Familial Mediterranean Fever

Background In this study we investigated the potential of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), and red cell width distribution (RDW) as new inflammatory markers to identify chronic inflammations during symptom-free periods in children diagnosed with Familial Mediterranean Fever (FMF). Material/Methods The study included 153 children diagnosed with FMF based on the Tel-Hashomer Criteria, and 90 healthy volunteers. Hospital records were obtained to collect NLR, PLR, MPV, RDW, and FMF scores and the FMF mutation analyses of the patients enrolled in the study. Data on proteinuria were also collected and defined as a protein/creatinine ratio >0.2. Results NLR, PLR, MPV, and RDW were significantly higher in symptom-free FMF patients than in the control group. C-reactive protein values also weakly correlated with NLR, PLR, MPV, and RDW, but the correlation was not statistically significant. NLR had the strongest correlation with CRP. The NLR cut-off point to indicate subclinical inflammation in symptom-free FMF patients was calculated to be 1.65. Conclusions NLR, PLR, MPV, and RDW are potential subclinical inflammation markers in patients with FMF. NLR, PLR, MPV, and RDW values are higher in patients with FMF during symptom-free periods. NLR was found to be the most reliable marker for subclinical inflammation when compared to PLR, MPV, and RDW. We also found that these markers are not significantly higher in proteinuric patients when compared with levels in non-proteinuric patients.

The relationship between the neutrophil-lymphocyte ratio and disease activity in patients with ulcerative colitis.

Preliminary evidence suggests that a higher neutrophil–lymphocyte ratio (NLR) may be an indicator of active ulcerative colitis (UC). However, it is not clear whether the NLR is a useful and simple indicator of clinical activity in UC after adjusting for the other inflammatory markers. We designed a retrospective study to evaluate the role of the NLR in estimating disease severity in UC patients. The study consisted of 71 patients with UC and 140 age‐ and sex‐matched healthy individuals (control group). The NLR, erythrocyte sedimentation rate, C‐reactive protein, and white blood cell count were measured. The NLR values of the active UC group were elevated compared with those of the patients with inactive UC and the controls (2.59 ± 1.47, 2.03 ± 1.07, and 1.98 ± 0.85, respectively; p = 0.005). The receiver operating characteristic revealed that the optimum NLR cut‐off point for active UC was 2.39. A multivariable logistic analysis showed that of the parameters studied, C‐reactive protein was the only parameter able to significantly discriminate active from inactive UC (B: 0.222; p = 0.017; odds ratio: 1.248; 95% confidence interval: 1.041–1.497).

RELATIONSHIPS AMONG THYROID HORMONES AND OBESITY SEVERITY, METABOLIC SYNDROME AND ITS COMPONENTS IN TURKISH CHILDREN WITH OBESITY.

BACKGROUND we investigated the relationships between thyroid function and obesity severity, metabolic syndrome (MS) and MS components in 260 obese children and adolescents 10-17 years of age. OBJECTIVES we aimed to determine the association of thyroid functions with obesity severity and the components of metabolic syndrome (MS) in pediatric obese patients. METHODS only obese children and adolescents were included, and divided the obese children into three groups according to body mass index (BMI)-SDS quartiles. The first quartile was group 1, the second and third quartiles were group 2, and the fourth quartile was group 3. Group 3 indicated severe obesity. The modified WHO criteria adapted for children were used to diagnose MS. We assessed anthropometric data and serum biochemical parameters, including the lipid profile and fasting glucose (FG), insulin, thyroid-stimulating hormone (TSH), free thyroxine (fT4), and free triiodothyronine (fT3) levels. Blood pressure (BP) was measured with a standard digital sphygmomanometer. The homeostasis model assessment of insulin resistance was calculated to determine insulin resistance (IR). RESULTS TSH level was significantly higher in obese children with MS than that in the others (p = 0.045). Mean TSH level was not different among the BMI-SDS groups (p = 0.590). TSH levels and the fT3/fT4 ratio were not different in children with dyslipidemia, IR or hypertension (p = 0.515, 0.805, 0.973, 0.750, 0.515, and 0.805, respectively). DISCUSSION obesity severity does not affect TSH level or the fT3/fT4 ratio in obese children and adolescents. IR is in close relationship with TSH level. Elevated TSH level is a risk factor for MS.

Evaluation of executive functions in children and adolescents with familial Mediterranean fever

ABSTRACT The aim of the present study was to investigate neuropsychological test performance in children and adolescents with familial Mediterranean fever (FMF). A total of 88 children and adolescents aged 8 to 17 years were included, 52 with FMF and 36 healthy controls. After the participants were administered the Children Depression Inventory (CDI) and the Screen for Child Anxiety Related Emotional Disorders (SCARED), they completed the battery tests of the Central Nervous System Vital Signs (CNSVS), a neurocognitive test battery, via computer. The battery calculates seven domain scores (Memory, Psychomotor Speed, Processing Speed, Reaction Time, Complex Attention, Executive Function, and Cognitive Flexibility) and a summary score (Neurocognition Index [NCI]). A statistically significant difference between the FMF and control groups was found in six out of seven domains, where the scores of the participants with FMF were found to be significantly lower than those of the control participants (p < .05). Although the mean Reaction Time score of the participants with FMF was found to be lower than that of the control participants, the finding was not statistically significant (p > .05). The mean CDI and SCARED scores of the participants with FMF were found to be significantly higher than those of the control participants (p < .05). Low scores in the Processing Speed and Psychomotor Speed domains of the CNSVS were significantly correlated with higher SCARED scores (r = −.37, p = .01). Impaired cognitive functions should be taken into consideration in children and adolescents with FMF when assessing and managing this population.

GENETIC ASSOCIATION BETWEEN ARTERIAL STIFFNESS-RELATED GENE POLYMORPHISMS IN BRVO AND CRVO PATIENTS IN A TURKISH POPULATION.

Purpose: To investigate possible associations between five different single-nucleotide polymorphisms, from genes associated with arterial stiffness and branch retinal vein occlusion (BRVO), or central retinal vein occlusion. Methods: A total of 187 patients with retinal vein occlusion (133 with BRVO and 54 with central retinal vein occlusion), and 167 controls, were enrolled in this study. All subjects were screened for hypertension, diabetes, smoking status, body mass index, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, total cholesterol, and very low-density lipoprotein. The genotyping of adiponectin +276 G/T, ACE I/D, AGTR1 A1166C, eNOS E298D, and p22phox −242 C/T polymorphisms was performed using real-time polymerase chain reaction. Results: The percentage of the adiponectin +275 T allele carriers was significantly higher in the BRVO patients (37%) than in the controls (23%, P < 0.001). Similarly, the percentage of AGTR1 1166 C allele carriers was significantly higher in the BRVO patients (38%) than in the controls (24%, P < 0.001). At the multiple logistic regression analysis, the adiponectin +275 T allele carrier and AGTR1 1166 C allele carrier status were found to be associated with an increased risk of BRVO (TT vs. GG and TG: odds ratio = 2.278, P = 0.002, 95% confidence interval: 1.370–3.789; CC vs. AA and AC: odds ratio = 1.804, P = 0.025, 95% confidence interval: 1.079–3.017). The genotype distributions or allelic frequencies of ACE I/D, eNOS E298D, and p22phox −242 C/T did not significantly differ between the patients with BRVO and the control subjects. There was no significant difference between the central retinal vein occlusion patients and controls for the genotype or the allele frequency distributions of all evaluated single-nucleotide polymorphisms. Conclusion: Adiponectin +276 G/T and AGTR1 A1166C single-nucleotide polymorphism are likely to be risk factors for BRVO.

Does Prolidase Indicate Worsening of Hepatitis B Infection

Hepatitis B infection is a health problem that affects more than 400 million people all over the world. We aimed to evaluate the usability of prolidase enzyme that plays an important role in collagen synthesis. Prolidase levels increase in hepatic damage, which can be used as diagnostic parameters in the progressions to chronic hepatitis B (CHB) infection by evaluating it in different clinical forms of hepatitis B infection.

Caffeic acid phenethyl ester as a remedial agent for reproductive functions and oxidative stress-based pathologies of gonads.

In recent years, the studies on the roles of caffeic acid phenethyl ester (CAPE) in several disease models and cell cultures are tremendously growing. It is such a great molecule that was used by ancient times to ameliorate some diseases and nowadays, it is used by modern medicine to test the effectiveness. In this mini-review article, the protection capability of CAPE, as a liposoluble antioxidant and a potent nuclear factor kappa B inhibitor, on oxidative and non-oxidative ovary, and testis damages has been summarized. In view of our laboratory findings/experience and those reported in the hitherto literature, we suggest that CAPE possesses protective effects for pathologies of the reproductive organs induced by untoward effects of harmful molecules such as free oxygen radicals, pesticides, methotrexate, and MK-801 (dizocilpine).

Prevalence of hypercalciuria and urinary calcium excretion in school-aged children in the province of Tokat

AIM Hypercalciuria is an important cause of urinary tract symptoms, and also frequently results in urolithiasis. Urinary calcium excretion varies for geographic areas. We aimed to assess percentiles of urinary calcium excretion and prevalence of hypercalciuria for school-aged children in Tokat (city located in inner northern region of Turkey). MATERIAL AND METHODS One thousand three hundred seventy-five children aged 6 to 18 years were enrolled in the study. Urine samples were obtained randomly. The childrens variables as sex, age, length, and weight were recorded. Urinary calcium and creatinine determined from the urine samples and urinary calcium/creatinine ratios (mg/mg) were calculated. Percentiles of urinary calcium/creatinine ratios were also assessed for each age of the children. RESULTS Six hundred eighty-three of the 1 375 children were girls and 692 were boys. The mean age of the children was 11.68±3.43 years. Some 23.9% of the children were living in rural regions and 76.1% were were living in urban regions. The mean urinary calcium/creatinine ratio was 0.080±0.24 and the 95th percentile value of the urinary calcium/creatinine ratio was 0.278. The hypercalciuria prevalence for school-aged children was 4.7% when the urinary calcium/creatinine ratio value for hypercalciuria was accepted as ≥0.21. The prevalence of hypercalciuria in rural and urban regions was 7.60% and 3.82%, respectively (p<0.05). Hypercalciuria was present in 7 of 141 patients who were obese (4.96%) and 58 of 1 234 patients who were not obese (4.70%) (p>0.05). CONCLUSION The prevalence of hypercalciuria and urinary calcium excretion vary for different geographic areas, not only for countries. The percentiles of urinary calcium excretion should be assesed for every geographic region and the prevalance of hypercalciuria should be determined with these values. There is controversy as to whether obesity is a risk factor for hypercalciuria.
