Accuracy of Cerebrospinal Fluid C-Reactive Protein and Multiplex Polymerase Chain Reaction and Serum Procalcitonin in Diagnosis of Bacterial and Viral Meningitis in Children.

BACKGROUND: Meningitis is one of the most dangerous infection affecting children. The need for rapid and accurate diagnosis is mandatory for improving the outcome. AIM OF THE WORK: to evaluate the role of multiplex polymerase chain reaction (PCR), cerebrospinal fluid (CSF)-C-reactive protein (CRP) and serum procalcitonin (PCT) in diagnosis of meningitis and to detect its accuracy. PATIENTS AND METHODS: A cross-sectional study was carried out in University Children hospital, Faculty of Medicine, between November 2019 and September 2020. The study was approved by the Ethics Review Board of Faculty of Medicine, Assiut University, and informed written consent was obtained. The committee's reference number is 17200161. CLINICALTRIALS: gov ID: NCT03387969. 48 Children aged 2 to 18 years with meningitis were included. Detailed history and examination. Blood glucose level at time of admission prior to lumbar puncture, serum CRP level, serum PCT, CSF-CRP level and Multiplex PCR were evaluated. FUNDING: The study was supported by Grant Office of Faculty of Medicine, Assiut University with grant NO. 2018-01-04-006-R2. RESULTS: The mean age of children was 3.27 plus or minus 1.27 years. 35 (72.9%) cases were bacterial meningitis, while 13 (27.1%) cases were viral meningitis. Patients with bacterial meningitis had significantly higher serum CRP, serum PCT and higher CSF-CRP and significantly lower CSF/blood glucose compared to viral meningitis. Multiplex PCR had 94% sensitivity and 100% specificity for diagnosis of bacterial and viral meningitis. CONCLUSION: CSF-CRP, CSF/blood glucose, PCT and Multiplex-PCR may help in diagnosis and differentiation of bacterial and viral meningitis.

Ovarian reserve in adolescent girls with autoimmune thyroiditis.

Objective: To assess serum anti-Müllerian hormone (AMH) levels as an ovarian reserve marker in adolescent girls with autoimmune thyroiditis (AIT) and explore the relationship of this marker with autoimmunity and thyroid function biomarkers. Subjects and methods: This study included 96 adolescent girls with newly diagnosed AIT and 96 healthy, age- and sex-matched controls. All participants were evaluated with detailed history taking and physical examination, thyroid ultrasound, and measurement of levels of thyroid-stimulating hormone (TSH), free thyroxin (FT4), free triiodothyronine (FT3), antithyroid peroxidase antibodies (TPOAb), antithyroglobulin antibody (TGAb), estradiol, total testosterone, and anti-Müllerian hormone (AMH) levels. The LH/FSH ratio was also calculated. Among 96 patients evaluated, 78 were overtly hypothyroid and 18 were euthyroid. AMH levels were significantly lower in participants with overt hypothyroidism and euthyroidism compared with controls. Results: Serum levels of AMH correlated negatively with age, body mass index (BMI) standard deviation score (SDS), and TPOAb, TGAb, and TSH levels but positively with FT4 levels. In multivariate analysis, AMH levels correlated significantly with age (odds ratio [OR] = 1.65, 95% confidence interval [CI] 1.18-2.32, p = 0.05), BMI SDS (OR = 2.3, 95% CI, 2.23-3.50, p = 0.01), TSH (OR = 2.43, 95% CI 1.5-2.8, p = 0.01), and TPOAb (OR = 4.1, 95% CI 3.26-8.75, p = 0.001). Conclusion: Ovarian reserve of adolescent girls with AIT, as measured by serum AMH levels, is affected by thyroid autoimmunity and hypothyroidism, indicating a possible need for ovarian reserve monitoring in these patients.

Evaluation of the effectiveness of valproic acid for treating cyanotic breath holding spells: A Pilot prospective study.

BACKGROUND: Cyanotic breath-holding spells (CBHS) are self-limited conditions among younger children. Frequent spells cause parents' fear and anxiety. Seizures, brain damage and sudden death have been rarely reported with BHS. Some reported spells' frequency reduction with iron or piracetam. We evaluated the effectiveness of valproic acid (VPA) to treat CBHS and predictors of improvement. METHODS: Participants were 90 children with CBHS (≥4/week) (age: 1.6±0.4yrs). They were treated with VPA (5 mg/kg/d). Follow-ups occurred after 3-≥6 months. Autonomic nervous system functions were evaluated. RESULTS: The majority (74.4%) had daily spells and 19% had ≥2 spells/d. Crying or anger provoked spells. Postural hypotension was found in 46.7%. They had normal electroencephalography and QT, QTc interval or QTd or QTcd and heart rate. Compared to controls, postural fall in systolic (>20mmHg) and diastolic (>10mmHg) blood pressures and mean arterial pressure (>10mmHg) were observed in 46.7%, 74.4% and 72.2% and miosis observed with 0.125% pilocarpine in 28.9% (P=0.001). Spells' frequency reduction (P=0.001) occurred within 3 months with VPA. The independent prdictors for spell' frequency reduction were reduction of anger and crying [OR=4.52(95%CI=2.35-6.04), P =0.01]. CONCLUSION: VPA therapy reduces CBHS' frequency. Mood improvement is a suggestive effective mechanism. CLINICAL TRIAL REGISTRATION: www.clinicaltrials.gov identifier is NCT04482764.

Familial glucocorticoid deficiency presenting with generalized hyperpigmentation in an Egyptian child: a case report.

INTRODUCTION: Familial glucocorticoid deficiency, or hereditary unresponsiveness to adrenocorticotropic hormone, is a rare autosomal recessive disease characterized by glucocorticoid deficiency in the absence of mineralocorticoid deficiency. It may present in infancy or early childhood with hyperpigmentation, failure to thrive, recurrent infections, hypoglycemic attacks and convulsions that may result in coma or death. Here, we report the case of an 18-month-old Egyptian boy with familial glucocorticoid deficiency. CASE PRESENTATION: An 18-month-old Egyptian boy was referred to our institution for evaluation of generalized hyperpigmentation of the body associated with recurrent convulsions; one of his siblings, who had died at the age of nine months, also had generalized hyperpigmentation of the body. The initial clinical examination revealed generalized symmetrical deep hyperpigmentation of the body as well as hypotonia, normal blood pressure and normal male genitalia. He had low blood glucose and cortisol levels, normal aldosterone and high adrenocorticotropic hormone levels. Based on the above mentioned data, a provisional diagnosis of familial glucocorticoid deficiency was made, which was confirmed by a molecular genetics study. Oral hydrocortisone treatment at a dose of 10 mg/m2/day was started. The child was followed up after two months of treatment; the hyperpigmentation has lessened in comparison with his initial presentation and his blood sugar and cortisol levels were normalized. CONCLUSION: Familial glucocorticoid deficiency is a rare, treatable disease that can be easily missed due to nonspecific presentations. The consequences of delayed diagnosis and treatment are associated with high rates of morbidity and mortality.

Predictors of glycemic control in children with Type 1 diabetes mellitus in Assiut-Egypt.

BACKGROUND: Type 1 diabetes mellitus (T1DM) may lead to severe long-term health consequences, such as renal failure, blindness, as well as heart and cerebrovascular disease. Although a direct relationship between blood glucose control and diabetes complications remains to be established beyond doubt, most diabetologists aim to achieve the best possible glucose control in their patients with T1DM. The aim of this study was to detect the predictors of glycemic control among children with T1DM in Assiut Governorate-Egypt. MATERIALS AND METHODS: We enrolled 415 children aged 2 to 18 years with type 1 diabetes of >1-year duration. They were subjected to full history including demographic factors and disease-related factors. Examination was done with determination of the body mass index, and assessment of stage of maturity. Investigations included hemoglobin A1c (HbA1c) and lipid profile. Patients with HbA1c above the recommended values for age by the American Diabetes Association were considered as poor glycemic control group. RESULTS: Of the studied cases, 190 cases (45.8%) were of poor glycemic control. Patients with poor control had significantly higher mean age (16.83 ± 3.3 vs 9.77 ± 3.7, P<0.000). Girls aged 15 years or more had significantly higher prevalence of poor glycemic control than males of the same age group. As regard the disease-related factors, patients with poor control had significantly longer duration of disease (7.94 ± 2.6 vs 2.40 ± 2.0, P<0.000) and were older in age at onset of disease. Insulin regimen which consists of basal bolus insulin plus three injections of regular insulin was associated with more frequency of good glycemic control than other regimens. Patients with poor control had significantly higher mean of cholesterol, triglyceride (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol than patients with good control. Adjusting for other variables, age of the patients, duration of disease, and serum TG level were significant independent risk factors of poor glycemic control. CONCLUSIONS: This study concluded that children more than 15 years, duration of disease more than 5 years, and high serum TG level are the predictors of poor glycemic control of children with T1DM in Assiut - Egypt. Pediatricians need to be aware of factors associated with poor glycemic control in children with T1DM, so that more effective measures can be implemented to prevent deterioration in diabetes control .
