RESUMEN
BACKGROUND: Pandemic period may affect aeroallergen sensitization. OBJECTIVE: The study aimed to investigate changes in allergen sensitivities of skin prick test (SPT) in patients with allergic rhinitis (AR) during pandemic and to evaluate relationship with disease severity. METHODS: In all, 164 AR patients with or without asthma, aged 6-17 years, who have undergone SPTs prior to the pandemic and after October 1, 2021 (18th month of the pandemic), were evaluated retrospectively. The wheal size of allergens in performed SPTs during and prior to the pandemic were compared. Detected changes in allergen sensitivities via SPT results were compared with changes in the disease severity parameters (AR severity, asthma severity, and the number of asthma exacerbations per year), frequency of upper respiratory tract infections and antibiotic use, laboratory parameters, demographic characteristics, and visual analogue scores (VAS). RESULTS: House dust mites (HDMs), cat, pollen, Artemisia, and Cupressus sensitization increased in AR patients during the Coronavirus disease 2019 (COVID-19) pandemic. HDM, mold, and pollen wheal diameters increased in SPTs. Proportion of polysensitization increased during the pandemic, compared to pre-pandemic period (9.1% vs 3%; P < 0.001), and number of non-sensitized patients decreased during the pandemic period compared to the pre-pandemic period (7.9% vs 22.6%; P < 0.001). An increase in HDM sensitivity in SPTs was correlated with VAS for nasal blockage, and an increase in cat sensitivity was correlated with VAS for all nasal symptoms. CONCLUSION: We believe that inhalant allergen sensitization might have been affected by the lifestyle changes of patients during the pandemic. Hence, it is important to evaluate patients for allergen sensitization, especially patients with moderate/severe AR, to revise disease control measurements.

OBJECTIVE: This study aimed to evaluate the knowledge, attitude, and practices of parents about breastfeeding, complementary food, and infant nutrition who have healthy infants born at term and under 2 years of age. MATERIALS AND METHODS: This is a cross-sectional study conducted among the parents of infants who came for well-child visits to pediatric clinics of 4 hospitals. Healthy infants under 2 years of age and who had been born at term were interviewed. The questionnaire included 35 questions to evaluate parents' knowledge, attitude, and practices about breastfeeding and infant nutri- tion in addition to sociodemographic data. Data were obtained via questionnaire and were analyzed using Statistical Package for the Social Sciences 20.0 package program. RESULTS: The study group consisted of 679 infants and their parents. The median durations of exclusive breastfeeding and total breastfeeding time were found to be 4 months and 10 months. Although 75% of the participants stated that infants must be exclusively breastfed for 6 months, the rate of exclusive breastfeeding for the first 6 months was 44%. The 393 (58%) participants used formula for infant nutrition and 47 (12%) of those started with complementary feeding. 90% of the participants stated that formula advertisements did not affect their decision on starting formula but the rate of thinking that other people may be affected by the advertisements was 80%. CONCLUSION: The knowledge of parents on human milk is not insufficient but they need to be supported especially to continue exclusive breastfeeding during the first 6 months and appro- priate complementary food during the weaning period.
RESUMEN
Studies describing paediatric sleep patterns are needed by taking culture into consideration. The aim of this study was to identify parent-reported sleep-wake patterns in young children and explore possible factors influencing sleep problems. The mothers of 2,434 young children enrolled from well-child outpatient clinics in Turkey completed an online survey including sociodemographic variables, Brief Infant Sleep Questionnaire, Edinburgh Postnatal Depression Scale and Generalised Anxiety Disorder scales. Overall, young children in Turkey go to bed late (10:00 p.m.), awaken twice per night for 30 min, and obtain 11.5 h of total sleep, showing no sex-specific differences. Distinct night-time sleep patterns emerged after 18 months of age. Importantly, although currently breastfed healthy children were 3.8-times less likely to sleep through the night, total sleep duration and exclusive breastfeeding duration were higher in children who were not sleeping through the night. Overall, bedsharing was identified in 11.5%, and only room sharing was reported in 52.9%. Parental perception of a child's sleep as problematic was 35.8%. Mothers with higher educational attainment were more likely to perceive their children's sleep as a problem. Maternal depressive and anxious symptoms and a history of excessive infant crying were the determinants predicting the likelihood of both parent-perceived sleep problems and poor sleepers. The present analysis of sleep structure in infancy and toddlerhood provides reference data for well-child visits. These findings highlight the importance of considering maternal anxiety, depression and behaviour management techniques to cope with fussy infants in addressing childhood behavioural sleep problems.

BACKGROUND: Periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome is the most common cause of periodic fever in childhood. This study aimed to investigate sleep patterns and possible factors that are associated with sleep disturbances among children with PFAPA syndrome. METHODS: Sixty-two patients with PFAPA and 68 age and sex matched healthy controls were enrolled in the study. Patients who had an attack during the former 2 weeks were not included. Demographic and anthropometric data, duration of fever episodes, laboratory results, and clinical manifestations of patients were recorded. The Children`s Sleep Habits Questionnaire was administered. RESULTS: The total sleep scores of patients with PFAPA were significantly higher than the control group (49.6 ± 10.7 vs. 38.3 ± 7.5, p = 0.002 ). Children with PFAPA had significantly higher scores regarding sleep-onset delay, sleep anxiety and night wakening (p=0.003, p=0.007, and p=0.014, respectively). Total sleep durations were similar between children with PFAPA and the control group. There was a significant positive correlation between the total sleep score and disease duration (r=0.425, p=0.002). Also there was a significant positive correlation between disease duration and sleep onset delay (r=0.561, p < 0.001) and night wakening (r=0.327, p=0.003). CONCLUSION: This study showed for the first time that patients with PFAPA have significantly disturbed sleep when compared to otherwise normal children. This study emphasized the need to assess sleep problems in children with PFAPA.

BACKGROUND: Burkholderia cepacia complex (Bcc) comprises multi-drug resistant, Gram-negative, motile, and aerobic bacteria. Bcc causes severe nosocomial infections particularly in patients with intravascular catheters and in those with cystic fibrosis. We studied a Bcc outbreak in non-cystic fibrosis patients. METHODS: We analyzed data from six patients hospitalized at our center. Blood cultures identified as infectious were incubated onto 5% blood sheep agar, chocolate agar, and eosin methylene blue (EMB) agar. We examined possible sites that could be sources of infection at the clinic. We confirmed isolations with pulsed-field gel electrophoresis (PFGE) tests. RESULTS: The first patient was hospitalized due to left renal agenesis, urinary tract infection, and renal failure. Bcc was isolated in blood cultures obtained due to high fever on the third day of hospitalization. We stopped new patient hospitalizations after detecting Bcc in blood cultures of other five patients. We did not detect further positive specimens obtained from other clinic and the patient rooms. PFGE patterns were similar in all clinical isolates of Bcc indicating that the outbreak had originated from the source. CONCLUSIONS: Bcc infection should be considered in cases of nosocomial outbreaks of multi-drug resistant organisms that require hospitalization at intensive care units. Control measures should be taken for prevention of nosocomial infections and required investigations should be done to detect the source of infection.

Obesity in children appears to be associated with increased risk of cardiovascular and metabolic diseases later in life. Early development of insulin resistance (IR) may lead to endothelial dysfunction and increased carotid intima-media thickness (cIMT) even in childhood. We compared endothelial cell-specific molecule-1 (endocan) levels in pediatric obese patients with those in healthy controls to determine whether endocan could be used as a biological marker of complications caused by endothelial damage. In 80 obese pubertal children (44 males [M] and 36 females [F], mean age: 12.8 ± 2.5 years), anthropometric measurements, cIMT, endocan levels, and IR indices (homeostasis model assessment of insulin resistance [HOMA-IR]) were evaluated and compared with 80 healthy pubertal patients (42M/38F, mean age: 12.3 ± 3.2 years). High-resolution ultrasound was used to measure the cIMT. Obese children had higher levels of endocan compared with the controls (P < .001). Fasting insulin levels and HOMA-IR were also higher in obese children (P < .001 for both). In addition, obese children had an increased cIMT (P < .001). In obese children, there was a significant correlation between cIMT and HOMA-IR (ß = -1.314, P = .002) and between cIMT and endocan (ß = .483, P = .004). Measuring cIMT and endocan levels (noninvasive investigations) in obese children, together with early preventive measures, could significantly decrease morbidity and mortality in adulthood.

BACKGROUND: Recurrent aphthous stomatitis is one of the most prevalent oral mucosa diseases and the etiology is unclear. As a potent anti-inflammatory and immunomodulating agent, vitamin D can significantly affect oral cavity homeostasis. However, to the best of our knowledge, no study has been conducted in pediatric population on the potential role of vitamin D in recurrent aphthous stomatitis to date. The aim of the present study is to determine the vitamin D status in recurrent aphthous stomatitis in children. METHODS: This study is conducted retrospectively. Seventy-two patients with minor recurrent aphthous stomatitis and 70 age-matched healthy controls included in the study. 25-Hydroxyvitamin D levels were measured in all patients using enzyme immunoassay. RESULTS: Serum vitamin D levels were 16.4 (8.6) ng/mL in patient group and 23.1 (11.5) ng/mL in healthy controls. There was a statistically significant difference between the groups in terms of serum vitamin D levels (P = .002). There was no significant correlation between serum vitamin D levels and the severity of the recurrent aphthous stomatitis (r = 0.54, P = .76). CONCLUSIONS: Our study showed a significant difference in vitamin D levels between patients with recurrent aphthous stomatitis and the healthy control group. We also found no correlation between vitamin D status and the severity of the disease.

We measured brachial artery flow-mediated dilatation (FMD) and common carotid intima-media thickness (cIMT) in overweight (n = 67) and normal weight children (n = 115, controls). Age at examination ranged from 72 to 182 months (mean 123 ± 27). Compared to controls, the overweight children had increased weight, waist and hip circumference, systolic and diastolic blood pressures (all P < .001), right and left mean cIMT (mm; 0.58 [0.42-0.68] vs 0.44 [0.3-0.64], P < .001 and 0.56 [0.32-0.70] vs 0.44 [0.3-0.60], P < .001), respectively, and decreased FMD (%; 6.25 [3.33-19.05] vs 7.69 [3.45-16], P < .001). The cIMT and FMD were closely related to the serum insulin concentrations. Age, waist circumferences, and serum triglycerides were independent predictive risk factors for increased cIMT, and fasting glucose and BMI were independent predictive variables for decreased FMD. Overweight children are also potentially at risk of early atherosclerosis as much as obese children.

OBJECTIVE: The periodic fever, aphthous stomatitis, pharangytis and cervical adenitis (PFAPA) syndrome, is an idiopathic chronic disease of non-hereditary origin, primarily affecting pre-school children and is the most common periodic fever disorder in children. Rapid response to corticosteroid treatment suggest an immune dysregulation. Recently, emerging evidence suggest that vitamin D plays an important role in immunity regulation. The aim of our study was to assess the vitamin D levels in children with PFAPA syndrome. METHODS: This study was conducted prospectively. We have consecutively evaluated 50 patients after having excluded other causes of recurrent fever between May 2017 and May 2018 in addition to age-matched 50 patients as control group. All patients has complete physical examination and laboratory tests. Laboratory tests included complete blood count, C-reactive protein (CRP), and vitamin D levels. Serum 25 (OH) vitamin D levels were measured in all patients twice yearly. RESULTS: Vitamin D levels was 18⯱â¯10â¯ng/ml in the patient group and 35⯱â¯13â¯ng/ml in the control group. There was statistically significant difference between the groups (pâ¯<â¯0.001). 38 patients from the PFAPA group and 20 patients from the control group had low vitamin D levels. Multivariate logistic regression analysis showed that CRP (odd ratio (OR)â¯=â¯2.7, 95% confidence interval (CI)â¯=â¯2.4-4.1) and serum 25 (OH) vitamin D levels <30â¯ng/ml ORâ¯=â¯2.1, 95% CIâ¯=â¯1.8-2.5) were associated with PFAPA occurrence. CONCLUSION: We found strong correlation between PFAPA and vitamin D insufficiency. Hypovitaminosis D can be a significant risk factor for PFAPA episode recurrence.

Background/aim: Various studies have shown that adult patients with polycystic ovary syndrome (PCOS) have higher levels of anxiety and depression compared to their normal counterparts. However, it is still unclear whether these mood disorders already exist in adolescents affected by PCOS. The aim of the present study is to assess differences in anxiety and depression levels between adolescents with PCOS and age- and body mass index (BMI)-matched controls and to determine the possible factor(s) impacting these psychological parameters in adolescents with PCOS. Materials and methods: The study included 80 adolescents with PCOS and 50 age- and BMI-matched controls. All participants completed standardized questionnaires assessing anxiety and depression. A multiple linear regression model was used to analyze the impact of potential variables on anxiety and depression scores of the adolescents with PCOS. Results: Significantly higher levels of anxiety, specifically generalized and social anxieties, as well as depression were found in adolescents with PCOS compared to controls. Higher BMI was found to be associated with higher levels of depression and generalized anxiety, and higher modified Ferriman-Gallwey score with higher level of panic disorder in adolescents affected by PCOS. Conclusion: Adolescents with PCOS experience significantly more emotional distress compared to adolescents without PCOS. This emotional distress may be related, at least in part, to certain clinical features of PCOS including obesity and hirsutism. PCOS in adolescents should be assessed not only for the gynecological and metabolic aspects but also for the emotional aspects of the disease.
RESUMEN
BACKGROUND: Infertility is a problem concerning 10-15% of the individuals in the fertile period. This study investigated effects of proinflammatory factors as well as lipid hydroperoxides (LPO) levels upon in vitro fertilization (IVF) success. MATERIALS AND METHODS: In this prospective, non-randomized, controlled clinical study, sera obtained from 26 fertile (group-1), 26 infertile women before (group-2) and after (group-3) IVF treatment were analyzed. Leptin, leptin receptor, resistin, tumor necrosis factor-alpha (TNF-α), and C-reactive protein (CRP) were analyzed using enzyme-linked immunosorbent assay (ELISA). LPO was determined spectrophotometrically. Mann- Whitney U test, paired samples t test, Wilcoxon signed-rank test as well as Pearson correlation analysis by SPSS were performed for statistical analysis. RESULTS: TNF-α, resistin and LPO levels increased (P=0.020, P=0.003, P=0.001, respectively) in group-3 compared to group-2. A significant increase in LPO was noted both in group-2 and -3 compared to controls (P=0.000). LPO were higher in non-pregnants than pregnants in group-2. For pregnants, significant correlations were observed between leptin and resistin in group-2 and TNF-α and leptin in group-3. None of these correlations were found for the women, who could not conceive. CONCLUSION: LPO, leptin-resistin correlation, associations with TNF-α may be helpful during the interpretation of IVF success rates.
RESUMEN
The aim of this prospective case control study is to determine CD4(+), CD25(+), and FoxP3(+) T regulatory cells (Tregs) and T helper cells (Ths) in obese, asthmatic, asthmatic obese, and healthy children. Obese (n = 40), asthmatic (n = 40), asthmatic obese (n = 40), and healthy children (n = 40) were included in this study. Blood samples collected from children were marked with CD4, CD25, ve Foxp3 in order to detect Tregs and Ths by flow cytometric method. Statistical analyses were performed. p ≤ 0.05 was chosen as meaningful threshold. Tregs exhibiting anti-inflammatory nature were significantly lower in obese (0.16 %; p ≤ 0.001), asthmatic (0.25 %; p ≤ 0.01), and asthmatic obese (0.29 %; p ≤ 0.05) groups than control group (0.38 %). Ths were counted higher in asthma group than control (p ≤ 0.01) and obese (p ≤ 0.001) groups. T cell immunity plays important roles in chronic inflammatory diseases such as obesity and asthma pathogeneses. Decreased numbers of Tregs found in obese, asthmatic, and asthmatic obese children might represent a challenge of these cells.

OBJECTIVES: It is known that obesity is related to heart failure. Asymptomatic left ventricular diastolic dysfunction (LVDD) is associated with the development of heart failure. The relationship between subclinical LVDD and overweight in children is not clear. The purpose of this study was to evaluate the effect of body mass index (BMI) and waist circumference on left ventricular mass index (LVMI) and LVDD in overweight children. STUDY DESIGN: A total of 153 children were enrolled in the study. Of these, 91 were normal weight (age-adjusted BMI: 15-85 percentile), and 62 were overweight (age-adjusted BMI: 85-95 percentile). After measuring two-dimensional and M-mode echocardiographic variables, left and right ventricle diastolic functions were assessed by conventional and tissue Doppler imaging. RESULTS: Compared to controls, overweight children had increased left atrium, aortic and left ventricular diameters, left ventricular wall thickness, LVM and LVMI, and septal mitral annulus e', septal e'/a', lateral e', lateral e'/a', lateral tricuspid annulus e', and e'/a' values. There were negative correlations between tissue Doppler diastolic parameters (septal mitral annulus e', lateral mitral annulus e', lateral tricuspid annulus e', septal mitral annulus e'/a', lateral mitral annulus e'/a', and lateral tricuspid annulus e'/a') and BMI, waist circumference, insulin, HOMA index, as well as systolic and diastolic blood pressure. Positive correlations were found between LVMI and BMI and between LVMI and waist circumference. BMI was found to be the predictor of decreased mitral anulus septal e', septal e'/a', lateral e', lateral e'/a'. CONCLUSION: Compared with normal-weight children, overweight children have decreased LV diastolic function. BMI is associated with a reduction in LV diastolic function in overweight children.

Jacobsen syndrome (JS), a rare disorder with multiple dysmorphic features, is caused by the terminal deletion of chromosome 11q. Typical features include mild to moderate psychomotor retardation, trigonocephaly, facial dysmorphism, cardiac defects, and thrombocytopenia, though none of these features are invariably present. The estimated occurrence of JS is about 1/100,000 births. The female/male ratio is 2:1. The patient admitted to our clinic at 3.5 years of age with a cardiac murmur and facial anomalies. Facial anomalies included trigonocephaly with bulging forehead, hypertelorism, telecanthus, downward slanting palpebral fissures, and a carp-shaped mouth. The patient also had strabismus. An echocardiogram demonstrated perimembranous aneurysmatic ventricular septal defect and a secundum atrial defect. The patient was <3rd percentile for height and weight and showed some developmental delay. Magnetic resonance imaging (MRI) showed hyperintensive gliotic signal changes in periventricular cerebral white matter, and leukodystrophy was suspected. Chromosomal analysis of the patient showed terminal deletion of chromosome 11. The karyotype was designated 46, XX, del(11) (q24.1). A review of published reports shows that the severity of the observed clinical abnormalities in patients with JS is not clearly correlated with the extent of the deletion. Most of the patients with JS had short stature, and some of them had documented growth hormone deficiency, or central or primary hypothyroidism. In patients with the classical phenotype, the diagnosis is suspected on the basis of clinical findings: intellectual disability, facial dysmorphic features and thrombocytopenia. The diagnosis must be confirmed by cytogenetic analysis. For patients who survive the neonatal period and infancy, the life expectancy remains unknown. In this report, we describe a patient with the clinical features of JS without thrombocytopenia. To our knowledge, this is the first case reported from Turkey.

OBJECTIVE: The aim of this study was to investigate the effect of infliximab on experimentally induced ovarian ischemia/reperfusion injury (IRi). STUDY DESIGN: A total of 42 female rats were equally divided into 6 experimental groups; group 1: sham operation, group 2: 3-h ischemia, group 3 and 4: 3-h ischemia, 3-h reperfusion, group 5 and 6: 3-h ischemia, 24h reperfusion. In group 4 and group 6, 30 min before reperfusion, infliximab was administered intraperitoneally at a dose of 5mg/kg. Bilateral ovaries were removed for histopathologic and biochemical analysis. Serum MDA (sMDA), tissue MDA (tMDA), serum NO (sNO), tissue NO (tNO) and serum catalase concentrations were analyzed. Tissue damage of ovarian tissue was scored by histological examination. RESULTS: The infliximab administration significantly lowered the sNO, tNO and sMDA concentrations in group 4 compared to group 3 (p=0.041, p=0.025 and p=0.035, respectively). sNO, tNO and sMDA concentrations were also lower in group 6 when compared to group 5, but this differences were not significant (p>0.05). On the other hand, tMDA concentrations were lower in infliximab-applied groups when compared to ischemia/reperfusion groups (group 3 vs. 4 and 5 vs. 6) (p=0.045 and p=0.048, respectively). Moreover, histopathologic tissue damage scores in infliximab administration groups were significantly lower than in ischemia/reperfusion groups (p<0.001). CONCLUSION: Infliximab attenuates I/R-induced ovarian tissue injury in rats subjected to ischemia/reperfusion.

OBJECTIVES: The effects of obesity on atrial conduction and ventricular repolarization have been studied in detail, but these parameters have not been well documented in overweight children. The aim of our study was to investigate the effects of overweight on atrial conduction and ventricular repolarization in children by using P-wave dispersion (Pw-d) and QT dispersion (QT-d) analyses. STUDY DESIGN: Sixty-seven overweight children and 70 children within normal limits were included in this cross-sectional prospective controlled study. All subjects underwent electrocardiographic and anthropometric evaluation, and blood samples were obtained. Pw-d and QT-d were investigated between two groups. RESULTS: Homeostatic model assessment of insulin resistance levels were higher in the overweight group (2.9±1.2 vs. 1.1±0.8, p=0.001). No statistically significant differences were found in Pw-d and QT-d when the groups were compared. The following findings were recorded for the overweight and control groups, respectively: mean RR interval (635±42 msec vs. 645±45 msec, p=0.867), Pw-d [30 (10-55) msec vs. 27.5 (15-50) msec, p=0.441] and QT-d (30 (15-55) msec vs. 22.5 (10-60) msec, p=0.476). In addition, Pw-d and QT-d were not correlated with the levels of insulin or body mass index. CONCLUSION: There was no significant difference in atrial conduction or ventricular repolarization features between overweight children and normal-weight children.

OBJECTIVE: To investigate the relation between copeptin, arginine vasopressin (AVP), and nocturnal enuresis (NE). METHODS: Forty-four patients with NE and 44 healthy children aged between 6 and 14 years were enrolled. Patients with nonmonosymptomatic and secondary NE were excluded from the study. A small questionnaire, filled by parents, collected information about sociodemographic characteristics. Blood was obtained for plasma AVP and copeptin concentrations. RESULTS: Copeptin levels were significantly lower in patient group (3.74 ± 1.44 pg/mL) than the control group (16.57 ± 3.91 pg/mL), whereas AVP levels were not significantly different between groups. Copeptin levels were significantly lower in patients (3.17 ± 1.15 pg/mL) who had bed-wetting 2 or more nights a week, which is considered as severe bed-wetting, than the patients (4.95 ± 1.24 pg/mL) who had bed-wetting 1 night or less than 1 night a week. CONCLUSION: This study demonstrates the presence of decreased levels of copeptin in patients with NE compared with healthy patients. AVP levels were not different between groups. To our knowledge, this is the first report assessing the relationship between copeptin and NE.

BACKGROUND: The aim of our study is to investigate the effects of low birth weight (LBW) on atrial conduction and ventricular repolarization in children by using P-wave dispersion (Pw-d) and QT dispersion (QT-d) analyses. These effects have not yet been studied in detail in LBW children. METHODS: Fifty LBW children and 70 normal birth weight (NBW) children were enrolled in this cross-sectional controlled study. The Pw-d and QT-d of the LBW and NBW children were investigated. Independent Student's t-test, Mann-Whitney U test, and χ(2) test were performed to compare these two groups. Stepwise multiple regression analysis was performed to investigate whether there was a relationship between P-wave indices, QT derivatives, anthropometric and clinical features, and echocardiographic parameters. RESULTS: Age, gender, body mass index, waist circumferences, systolic and diastolic blood pressure, and echocardiographic measurements were similar between the LBW group and the NBW group (all P values > 0.05). The following findings were recorded for the LBW and NBW groups, respectively: the Pw-d (30 [10-50] ms vs 30 [10-50] ms, P = 0.977), QT-d (20 [10-50] ms vs 30 [15-50] ms, P = 0.561), and QTc-d (26 [14-54] ms vs 33 [17-62] ms, P = 0.866). No significant difference was found in Pw-d, QT-d, and QTc-d in comparison between the groups (all P values > 0.05). Pw-d was related to left atrial diameter and QTc-d was associated with left ventricle mass index even though they were within the normal range. CONCLUSION: Compared with the NBW group, no significant difference was found in both atrial conduction and ventricular repolarization features in LBW children.

OBJECTIVE: This study was designed to determine the current age-related hepatitis A virus (HAV) seroprevalance, vaccination status of children and to evaluate the epidemiological shift in HAV serostatus living in Tekirdag, which is located in Thrace region, the European part of Turkey. METHODS: Children 6 months-12 years of age with simple health problems were included. Blood samples were studied for HAV IgM and IgG collectively. A questionnaire addressing several characteristics of subjects was administered to obtain basic descriptive data on HAV epidemiology. Vaccination status of the children was recorded according to the immunization cards. FINDINGS: The overall anti-HAV IgM and anti-HAV IgG prevalance in children aged 6 months - 12 years was 3.3% and 25.4% respectively. Maximum hepatitis A IgM positivity was in the 7-12 years age group 4.8% (n= 12; P<0.001) and maximum hepatitis A IgG positivity in the same age group was 34% (n = 85; P<0.001). HAV vaccination rate among patients aged more than 2 years was 11.03%. HAV IgG seroprevalance was higher in children of low monthly income families (36.1%, n = 78; P<0.001) than in the intermediate (17%, n = 31) and high income families (11.1%, n = 6). CONCLUSION: These results indicate a shift in Hepatitis A seroprevalance when compared with the previous studies. As HAV infection in childhood is decreasing, the pool of susceptible adolescents and young adults is increasing. Introduction of hepatitis A vaccination into the national immunization schedule of Turkey should be considered.
