Item Can RDW be used as a screening test for subclinical inflammation in children with FMF? Is RDW related to MEFV gene mutations?(2023) Parmaksiz, Gonul; Noyan, Z. Aytul; 36103024Objective Subclinical inflammation, an insidious feature of familial Mediterranean fever (FMF), can lead to life-threatening amyloidosis. We aimed to investigate acute phase reactants and complete blood count parameters to identify a useful marker for subclinical inflammation in children with FMF. A secondary aim was to identify an association between subclinical inflammation and specific Mediterranean fever (MEFV) gene mutations. Methods This study included 420 pediatric patients with FMF. Laboratory parameters of patients during the attack-free period and MEFV gene mutation analyses were recorded. Results Of the 420 patients, 88 (21%) had subclinical inflammation. Of those with subclinical inflammation, 48 (55%) had mutations in exon 10, 36 (41%) had M694V mutation, and 10 (11%) had M694V homozygous mutation. Red cell distribution width (RDW) value was higher in exon 10, M694V, and M694V homozygous mutations compared to other mutations. RDW was positively correlated with serum amyloid A (SAA) (r = 0.390, p = 0.0001). Analysis of a receiver-operating characteristic curve of RDW revealed that its optimal cut-off value for subclinical inflammation was 12.69%, its sensitivity was 64.10%, and its specificity was 50.90%. The area under the curve was 0.616 (p = 0.004, 95% confidence interval = 0.538-0.695). Conclusion We suggest that RDW can be used as a screening test as a marker of subclinical inflammation. A high RDW value should alert the clinician about subclinical inflammation in FMF children's patients with M694V (heterozygous, homozygous, compound heterozygous) mutation.Item The relationship between body mass index and renal length in obese children(2020) Parmaksiz, Gonul; Kekec, Senay Demir; Cengiz, Nurcan Dinler; Noyan, Aytul; 0000-0003-2373-1837; 31997076; AAD-5713-2021; AAM-2935-2021Background Obesity in the pediatric population is a severe public health problem and is associated with various comorbidities. Renal length is an important clinical parameter for the diagnosis and follow-up of renal diseases. The aim of this study was to determine the relationship between renal length (measured ultrasonographically) and body mass index (BMI) in obese children, and to develop nomograms for renal length according to BMI. Methods Renal ultrasound was performed in 368 children without renal disease. Each child's age, gender, weight, height, and BMI (kg/m(2)) were recorded. The children were divided into three groups according to BMI percentiles: obese group: BMI >= 95th percentile; overweight group: BMI 85th-94th percentile; normal weight group: BMI 5th-84th percentile. Results Weight, height, BMI, and right and left renal length differed significantly between the three groups (p = 0.001). There were significant correlations between renal length with age, weight, height, and BMI. Measurement of renal length was independently associated with BMI, age, and height. BMI was used to create renal length nomograms for obese children, based on multiple regression analysis (R-2 = 0.32 and p = 0.0001). Mean renal length was highest in the obese group (96.9 +/- 13.4 mm) and lowest in the normal weight group (88.3 +/- 12.9 mm). Conclusions Ultrasonographic measurement of the renal length according to BMI in children can be a useful method in evaluating these children. Smaller-than-normal kidneys can easily remain undiagnosed in obese and overweight children and this nomogram offers an additional method to evaluate the renal size in obese children.
