ATP binding Cassette gene member 1 (ABCB1) polymorphism has been incriminated in susceptibility to many malignant, infectious and autoimmune diseases. Recently, it was reported that ABCB1 polymorphisms might have a link to disease progression as well as response to therapy. We aimed to study the association between ABCB1 gene polymorphism and glucocorticoid response in children with newly diagnosed immune thrombocytopenia (ITP). A case control study was conducted on 90 newly diagnosed children with ITP and 90 healthy controls over a period of 1 year. ABCB1 (C3435T) polymorphism was determined by restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) in patients and controls. There was no significant difference between patients and controls as regards to frequency of different ABCB1 genotypes (CC, CT, and TT genotypes were 44.4%, 36.7%, and 18.9% respectively in patients and 48.9%, 38.9%, and 12.2% respectively in controls, P value = 0.18). 80% of patients who received steroids alone or steroids in combination with intravenous immunoglobulin showed complete recovery. There was highly significant relationship between ABCB1 genotypes and response to steroids where 55 % of responders had CC (wild) genotype while 40 % of nonresponders had TT (mutant) genotype. We concluded that ABCB1 gene polymorphism may contribute to the response to steroids in Egyptian children with ITP where patients with homozygous CC genotype responded better to steroids than patients with homozygous TT genotype. These results may help us choose the appropriate initial treatment in these children.

Concepts surrounding the mechanisms of thrombocytopenia in ITP have shifted from the traditional view of autoantibody mediated platelet destruction to more complex mechanisms in which impaired platelet production, T-cell-mediated effects, and disturbed cytokine profiles play a role. Interleukin 27 (IL-27) plays pleiotropic roles in immunomodulation and autoimmune diseases.We aimed to determine the level of IL-27 in patients with ITP and its relationship to patient and disease characteristics as well as disease chronicity and response to treatment.Sixty childrens with primary immune thrombocytopenia were consequetively enrolled in this study as well as 20 age and sex matched healthy controls.ITP patients had significantly higher levels of IL-27 than controls (770.6 and 373.8 pg/ml, respectively). Patients with acute ITP had the highest levels of IL-27 among patient groups, while patients in remission had the lowest IL-27 levels (860.1and 622.9 pg/ml, respectively). Patients who received IVIG and combined steroids plus IVIG had significantly higher IL-27 levels than others. Patients who received Eltrombopag had significantly lower IL-27 levels than others.IL-27 seems to play a role in pathogenesis of childhood ITP. IL-27 can be used as a predictor for disease occurrence as well as responsiveness to treatment.

We aimed to investigate the role of urinary kidney injury molecule-1 (KIM-1) in detection of subclinical nephrotoxicity in patients with Beta-thalassemia (β-TM) in relation to chelation therapy and to correlate the urinary KIM-1 level with other clinical and laboratory findings. We conducted a cross-sectional study on 66 thalassemic patients. Their ages range from 7 to 22 years. Routine kidney indices and novel urinary KIM/creatinine ratio (U

Acute lymphoblastic leukemia is the most common malignancy in children. In children, venous thromboembolism is relatively common. In most cases, venous thromboembolism manifests in patients who are diagnosed with acute lymphoblastic leukemia. Several risk factors associated with acute lymphoblastic leukemia predispose patients to the development of venous thromboembolism. Unlike most reported cases of venous thromboembolism, herein we report a child who developed cerebral venous sinus thrombosis prior to the diagnosis of acute lymphoblastic leukemia. The patient recovered from an attack of acute gastroenteritis with sepsis, pancytopenia, and disseminated intravascular coagulation 2 weeks before the development of thrombosis. Her laboratory workup for coagulopathy and disseminated intravascular coagulation was normal at the time of diagnosis of cerebral sinus thrombosis. The genetic workup for thrombophilia risk identified several genetic thrombophilia mutations: the homozygous factor XIII V34L and MTHFR A1298C mutations and heterozygous factor V Leiden mutation. Three weeks later, the patient was diagnosed with acute lymphoblastic leukemia. However, it remains questionable whether the thrombotic event was caused by the previous infection of gastroenteritis, sepsis, and disseminated intravascular coagulation picture (which was augmented by her genetic thrombophilia risk), or was it caused by acute lymphoblastic leukemia (that was not detected at early stages with its associated hypercoagulable state), or was it caused by a type of paraneoplastic syndrome. A multifactorial etiology is proposed.

In β-thalassemia, certain mutations cause a complete absence of β-globin chain synthesis, termed β 0 -thalassemia, while others may allow certain β-globin production and are termed β + - or β ++ -thalassemia. The homozygous state results in severe anemia, which requires regular blood transfusion. By contrast, frequent blood transfusion can in turn lead to iron overload, which may result in several endocrinal complica- tions. The present study aimed to investigate the impact of genotype on the development of endocrine complications in β-thalassemia patients. A cross-sectional study was conducted on 100 thalassemia patients >10 years. A data abstraction form was designed to capture the appropriate information from the individual medical records, including full clinical, laboratory, transfusion and chelation data. The genotype of the patients was identified by the DNA sequencing technique. Growth retardation and hypogonadism were the most promi- nent endocrinal complications (70 and 67%, respectively) followed by hypothyroidism, diabetes mellitus and hypo- parathyrodism (8, 8 and 7%, respectively). The most common mutations identified were IVS‑1‑110, IVS‑1‑1 and IVS‑1‑6 (63, 47 and 41%, respectively). Patients with the β 0 β 0 genotype had a significantly higher prevalence of growth retardation, hypogonadism, hypothyroidism and hypoparathyrodism compared to those with the β 0 β + and β + β + genotypes (P

Diabetes mellitus has been suggested to be the most common metabolic disorder associated with magnesium deficiency, having 25% to 39% prevalence. This deficit could be associated with the development of late diabetic complications, especially macroangiopathy. We aimed to evaluate the status of serum Mg in children with type 1 diabetes and assess its relation to glycemic control and lipid profile. We included 71 Egyptian children with type 1diabetes having their follow-up at Pediatric Endocrinology outpatient clinic, Zagazig University Hospital and 71 age- and sex-matched control. We measured Serum magnesium, HbA1c, and lipid profile in all study subjects. Diabetic children had significantly lower serum magnesium level compared to control children (1.83 ± .27 mg/dL in diabetic children versus 2.00 ± .16 mg/dL in control children). Taking cut-off level of serum magnesium

Bacille Calmette-Guérin vaccine (BCG) vaccination is used routinely in most of countries, especially developing one. The efficacy of the BCG vaccination generally decreases with time. The tuberculin skin test (TST) is a most popular diagnostic test for suspicion of tuberculosis (TB) in children till now, but it has many false positives. The interferon-gamma release assay (IGRA) is more specific than TST for detection of childhood TB, as it is more specific to Mycobacterium tuberculosis. Evaluate the interferon gamma response and TST reaction in BCG vaccinated children in east of Egypt. 150 children were included in the study aged 1 month to 12 years; the collected data from the children included, full history taking, clinical examination, examination for the presence or absence of BCG scar under direct light. All the children had performed TST, IGRA. TST was done for all studied group reveal 51.3% with size of reaction

Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 109/L, hemoglobin 8.7 g/dL and platelet count 197 × 109/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.
