THE VALUE OF THE MICROBIAL FLORA OF THE NASAL AND OROPHARYNGEAL MUCOSA IN THE FORMATION OF CLINICAL AND IMMUNOLOGICAL FEATURES OF INFECTIOUS MONONUCLEOSIS IN CHILDREN

Objective. The article presents the results of studies to determine the significance of the microbial flora of the nasal mucosa and oropharynx in the formation of the clinical course and immune response in children with infectious mononucleosis (IM). Materials and methods. Under the supervision were 93 children aged three to nine years, patients with mononucleosis. In 32 children (first group), Streptococcus pyogenes at concentrations of 10-5 and higher was isolated during bacteriological examination of the mucosa of the nasopharynx and oropharynx. 30 (second group) - 10-4 degrees or less. In 31 (the third group), Staphylococcus aureus, Spirochetae buccalis, E. Coli and other bacteria, except streptococcus, were sown in smears from the mucous membrane of the nasoropharynx. The immune status of patients was assessed by indicators of levels of lymphocytes CD3+, CD4+, CD8+, CD22+ and the content of interleukins 1β, 4, TNFα. Results. The acute period of the mononucleosis in children of the first group was characterized more severe symptoms of intoxication, more severe morphological changes in the tissues of the tonsils, lymph nodes, liver and spleen. Also a significant decrease in the relative amount of CD3+, CD4+, CD8+ was observed compared with the indicators of children of the second and third groups. The increase in blood CD22+ content was more significant in children of the first group. The content of pro-inflammatory IL-1β and TNF-α in patients of all groups was significantly higher than in healthy children. The IL-4 increased in children of the second and third groups. In the period of early convalescence in children of the second and third groups, the relative content of CD3+, CD4+, CD8+ cells approached the corresponding indices of the control group. This was not observed in children of the first group. CD22+ levels in all observation groups decreased by the convalescence period, but remained high compared with the control group. In children of the studied groups, by the period of reconvalescence, a decrease in the levels of IL-1β, TNF-α is noted, more significant in children of the second and third groups. At the same time, in children of the first group, the level of pro-inflammatory interleukins by the period of reconvalescence remained at high numbers. The content of IL-4 was a significant difference in the indicators of its content in comparison with the digital characteristics of healthy ones in children of the second and third groups. Conclusion. An analysis of the results of the study found that the presence of streptococcus in its high concentration on the mucosa of the nosopharynx of children with mononucleosis already contributes to the formation of cellular immunosuppression and a pronounced reaction of pro-inflammatory interleukins at the initial stage of the disease, which, in general, leads to aggravation of the clinical manifestations of the disease and, in our opinion, may be a causative factor of a possible unfavorable course of the disease.

Abstract In this study, we aimed to investigate epidemiologic factors in children with Acute Lymphoblastic leukemia (ALL). The parents of 105 children diagnosed and treated as ALL between the years 1997 –2007 in our Clinic of Pediatric Hematology-Oncology were questioned and results were compared with control group that consisted of 102 healthy children with similar age and gender. The mean age of the patients was 8.57 ± 3.95 years. The mean age at diagnosis was 5.87 ± 3.73 years. There was no significant difference between the groups in terms of type of delivery, birth weight, asphyxia at birth, resuscitation with high-concentration oxygen and ventilatory support (p>0.05). There was also no significant difference between the groups in terms of duration of breast feeding. The rate of exposure to infections prior to diagnosis was higher in control group (p:0.003). Besides that, the rate of going to nursery was also significantly higher in control group (p:0.014). There was no difference between the groups in terms of X-ray exposure (p>0.05). In conclusion over-protection from infectious agents in and delay in meeting with some specific agents seems to increase ALL risk. Infections in early infantile period can be protective against leukemia. There has to be more extended studies on this subject.

Abstract Objective To investigate the clinical characteristics, treatment, prognosis, and risk factors of chronic active EBV infection (CAEBV) associated with coronary artery dilatation (CAD) in children.Methods Children with CAEBV associated with CAD hospitalized in Beijing Children’s Hospital, Capital Medical University, from March 2016 to December 2019 were analyzed. At the same time, children with CAEBV without CAD were selected as the control group, matched by sex, age, treatment and admission time. The clinical manifestations, laboratory and ultrasonic examinations, treatment and prognosis of the children were collected in both groups.Results There were 10 children with CAEBV combined with CAD, accounting for 8.9% (10/112) of CAEBV patients at the same period, which including 6 males and 4 females, with onset age of 6.05 (2.8-14.3) years. The median follow-up time was 20 (6-48) months. All the patients had high copies of EBV-DNA in whole blood 1.18x107（1.90x105-3.96x107）copies/mL and plasma 1.81x104（1.54x103-1.76x106）copies/mL, and the Epstein-Barr virus encoded small RNA in biopsy was all positive. Among the 10 children, 8 had bilateral CAD, with 2 patients unilateral. After diagnosis, 7 children were treated with L-DEP chemotherapy in our hospital. After chemotherapy, four patients accepted allo-genetic Hematopoietic Stem Cell Transplantation (HSCT). The others were waiting for HSCT. By the end of the follow-up, CAD had returned to normal in 3 patients, and the time from diagnosis of CAD to recovery was 21 (18-68) d. The level of LDH, serum ferritin, TNF-α and IL-10 had statistically significant difference between the two groups (P=0.009, 0.008, 0.026 and 0.030). There were no significant differences in survival rate between the two groups (P=0.416).Conclusion The incidence of CAEBV with CAD was low. CAEBV with CAD did not influence the prognosis. Patients with CAEBV had high LDH, serum ferritin, TNF-α and IL-10 in the early onset were prone to have CAD.

Background: Cystic fibrosis (CF) is characterized by malnutrition and chronic inflammation predominantly occurring in lungs. Evidence suggests a relation between inflammatory activity and nutritional status. Proinflammatory cytokines, playing crucial role in pulmonary destruction in CF, are regarded as a component of the pathogenesis of illness-related malnutrition. Chemerin - a novel marker of a crosstalk between nutrition and inflammation, has not been investigated in children with cystic fibrosis. The aim of this study was to determine serum level of chemerin, interleukin-1b (IL-1b), interleukin-6 (IL-6), tumor necrosing factor α (TNF-α) and interleukin-10 (IL-10) and to verify if they correlate with the nutritional status in children with CF. Methods: The study included 72 pediatric patients with cystic fibrosis. The control group was comprised of 30 healthy children. Nutritional status parameters: Body Mass Index (BMI), fat mass percentage (FM %) and fat free mass percentage (FFM%) have been assessed in all the subjects basing on bioimpedance and anthropometry according to Slaughter. Serum concentrations of chemerin and cytokines were estimated with ELISA. Results: No statistically significant difference in serum chemerin was found between the studied and the control group. We have documented a significantly higher level of IL-1b, IL-6, TNF-α and IL-10 in CF patients when compared to healthy controls. Neither the chemerin nor the cytokine levels correlated with parameters of nutritional status in our cohort. No statistically significant correlation was found between the serum chemerin and the inflammatory cytokines: IL-1b, IL-6, and TNFα. Conclusions: Our results show that chemerin is not associated with the nutritional status in children with cystic fibrosis. Chemerin has no impact on the levels of IL-1b, IL-6, TNFα in CF patients. IL-1b, IL6, TNFα and also IL10 are upregulated in cystic fibrosis.

Abstract Objectives There are several hypotheses on the effects of the rs1738074 T/C single nucleotide polymorphism in the TAGAP gene; however, there has been no study on Turkish pediatric patients. We aimed to investigate the association of celiac disease (CD) and type 1 diabetes mellitus (T1DM) comorbidity with the polymorphism in the TAGAP gene of Turkish pediatric patients. Methods Totally, 127 pediatric CD patients and 100 healthy children were included. We determined the polymorphism by the allele-specific polymerase chain reaction method. We used IBM SPSS Statistics version 25.0 and Arlequin 3.5.2 for the statistical analyses. The authors have no conflict of interest. Results It was determined that 72% (n=154) of only CD patients had C allele, whereas 28% (n=60) had T allele. Of the patients with celiac and T1DM, 42.5% (n=17) and 57.5% (n=23) had T and C alleles, respectively. Of the individuals in control group, 67% (n=134) had C allele, whereas 33% (n=66) had T allele. Conclusions There was no significant difference in the genotype and allele frequencies between the patient and control groups (p>0.05). There was no significant association between the disease risk and the polymorphism in our study group.

AbstractThe aim of this study was to investigate the thyroid functions in children receiving levetiracetam or valproate monotherapy. We retrospectively reviewed the records of children with controlled epilepsy receiving valproic acid (VPA group) or levetiracetam monotherapy (LEV group) for at least 6 months. Free thyroxine 4 levels (fT4) and thyroid stimulating hormone (TSH) levels were compared between VPA group, LEV group, and age- and gender-matched healthy children (control group). A total of 190 children were included in the study: 63 were in the VPA, 60 in the LEV, and 67 in the control group. Although there was no significant difference regarding average fT4 levels, higher TSH levels were found in the VPA group when compared with the LEV and control groups (p < 0.001 and p < 0.001, respectively). There was no significant difference in terms of fT4 and TSH values in the LEV group when compared with the control group (p = 0.56 and p = 0.61, respectively). Subclinical hypothyroidism (defined as a TSH level above 5 uIU/mL with a normal fT4 level was detected in 16% of patients in the VPA group, none in the LEV and control groups. Our study found that VPA therapy is associated with an increased risk of subclinical hypothyroidism while LEV had no effect on thyroid function tests.

Experimental Pneumococcal Meningitis

ABSTRACT The polysaccharide fucoidin is a selectin blocker that inhibits leukocyte recruitment into the cerebrospinal fluid (CSF) during experimental pneumococcal meningitis. In the present study, the effect of fucoidin treatment on the release of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), and IL-8 into the CSF was investigated. Rabbits (n = 7) were treated intravenously with 10 mg of fucoidin/kg of body weight every second hour starting 4 h after intracisternal inoculation of ∼106 CFU of Streptococcus pneumoniae type 3 (untreated control group, n = 7). CSF samples were obtained every second hour during a 16-h study period. Treatment with fucoidin caused a consistent and significant decrease in CSF IL-1 levels (in picograms per milliliter) between 12 and 16 h (0 versus 170, 0 versus 526, and 60 versus 1,467, respectively;P < 0.02). A less consistent decrease in CSF TNF-α levels was observed in the fucoidin-treated group, but with no significant difference between the two groups (P > 0.05). In contrast, there was no attenuation in CSF IL-8 levels. Indeed, there was a significant increase in CSF IL-8 levels (in picograms per milliliter) in the fucoidin-treated group at 10 and 12 h (921 versus 574 and 1,397 versus 569, respectively;P < 0.09). In conclusion, our results suggest that blood-derived leukocytes mainly are responsible for the release of IL-1 and to some degree TNF-α into the CSF during pneumococcal meningitis, whereas IL-8 may be produced by local cells within the brain.

Objectives: Nocturnal enuresis (NE) is very common and is one of the most common causes for patients to be admitted to urology, pediatrics, child psychiatry and child surgery departments. We aimed to investigate the effect on depression and self-esteem of this disorder that can cause problems on person's social development and human relations. Material and methods: 90 patients who were admitted to our clinic with complaints of nocturnal enuresis were enrolled. Investigations to rule out organic causes were performed in this group of patients. Out of them 38 children and adolescents (age range 8-18 years) with primary monosymptomatic nocturnal enuresis (PMNE) agreed to participate in the study In the same period 46 healthy children and adolescents with a similar age range without bed wetting complaint were included in the study as a control group. The age of the family, educational and socioeconomic level were questioned and Piers-Harris Children's Self-Concept Scale (PHCSCS) and Children's Depression Inventory (CDI) forms were filled out. Results: Mean age of the cases (18 females or 47.4% and 20 males or 52.6%) was 10.76 ± 3.82 years whereas mean age of controls (26 females or 56.5% and 20 males or 43.5%) was 10.89 ± 3.11 years. Depression scale was significantly higher (p = 0.001) in the case group than in the control group (10.42 ± 4.31 vs 7.09 ± 4.35). In both groups there was no statistically significant difference by age and sex in terms of depression scale (p > 0.05). Conclusion: NE is widely seen as in the community and is a source of stresses either for children and for their families. When patients were admitted to physicians for treatment, a multidisciplinary approach should be offered and the necessary psychological support should be provided jointly by child psychiatrists and psychologists.

Background - Celiac disease is an autoimmune systemic disorder in genetically predisposed individuals precipitated by gluten ingestion. Objective - In this study, we aimed to determine asymptomatic spike-and-wave findings on electroencephalography in children with celiac disease. Methods - A total of 175 children with the diagnosis of celiac disease (study group) and 99 age- and sex-matched healthy children as controls (control group) were included in the study. In order to determine the effects of gluten free diet on laboratory and electroencephalography findings, the celiac group is further subdivided into two as newly-diagnosed and formerly-diagnosed patients. Medical histories of all children and laboratory findings were all recorded and neurologic statuses were evaluated. All patients underwent a sleep and awake electroencephalography. Results - Among 175 celiac disease patients included in the study, 43 were newly diagnosed while 132 were formerly-diagnosed patients. In electroencephalography evaluation of patients the epileptiform activity was determined in 4 (9.3%) of newly diagnosed and in 2 (1.5%) of formerly diagnosed patients; on the other hand the epileptiform activity was present in only 1 (1.0%) of control cases. There was a statistically significant difference between groups in regards to the presence of epileptiform activity in electroencephalography. Pearson correlation analysis revealed that epileptiform activity in both sleep and awake electroencephalography were positively correlated with tissue transglutaminase levels (P=0.014 and P=0.019, respectively). Conclusion - We have determined an increased epileptiform activity frequency among newly-diagnosed celiac disease patients compared with formerly-diagnosed celiac disease patients and control cases. Moreover the tissue transglutaminase levels were also correlated with the presence of epileptiform activity in electroencephalography. Among newly diagnosed celiac disease patients, clinicians should be aware of this association and be alert about any neurological symptoms.

Tuberculosis(TB) is aninfectious disease caused by Mycobacterium tuberculosis. The aim was to investigate the levels of immunomodulatory markers like interluekin-6 (IL-6), tumor necrotizing factor-α (TNF- α),cell differentiation-4 (CD4) and CD8 levels in those patients with active tuberculosis (TB) disease in comparison with control group. 41 Adults diagnosed with TB were included in comparison to 32 healthy individuals at Babylon health center for pulmonary diseases and TB. Descriptive data for patients and control group werecollected by well-trained researcher following a structured questionnaire. In parallel, peripheral blood collected to determine IL-6, TNF- α,CD4 and CD8. Then the assessment for the association between clinical and descriptive data and immunomodulatory markers levels was investigated statistically. The majority of TB patients were males (56%) and 71% were resident in rural areas; 47% of them were living in middle socioeconomic state,moreover,47% of TB cases had diabetes,furthermore,51% had chronic obstructive pulmonary diseases,12% had hypertension and 39% of them had chronic anemia with 47% smokers with no significant difference versus control. Following to that,there was highly increased in IL-6 and TNF-α levels in TB patients versus control (P<0.001),with low CD4 level versus control (P<0.001). While there was no significant change shown in CD8 levels versus control and this might highly be correlated with 30% of abnormal liver function tests among TB patients. A high proportion of TB patients have low CD4 level mostly associated with active disease. Moreover,the increase of IL-6 and TNF-α levels suggests a inverse impact on CD4 level which closely associated with the outcome of the disease.
