Background National evidence-based recommendations for diagnosis, treatment, imaging, and follow-up in urinary tract infection are crucial being a major health problem in pediatrics. Every region should follow international recommendations with respect to the disease local profile and available facilities for that area. Methods Based on AGREE II (the assessment tool of practice guidelines), Egyptian CGLs used *American Academy Pediatrics, *European Association Urology, European Society Pediatric Urology, and *Asian Association Urinary tract infections as its evidence-based references. Health questions were listed for evidence base answers adopted from selected CGLs after their permission. Key statements were approved by all members and further approved by the Egyptian Pediatric Guidelines Committee after local and international external peer reviewing. Results (1) Diagnosis recommendations: Urine culture with diagnostic colony counts is essential for diagnosis. Catheter samples are important for critical cases and non-toilet-trained cases especially when they show significant bacteriuria and pyuria. (2) Treatment plan included areas of debate as choice of antibiotic, oral versus intravenous, duration, antibiotic prophylaxis considering age, disease severity, recurrence, + risk factors, and imaging reports. (3) Imaging recommendations were tailored to suit our community. Renal bladder ultrasound is important for children with febrile UTI, due to the high prevalence of congenital anomalies of the kidney and urinary tract, paucity of prenatal ultrasound, and lack of medical documentation to reflect previously diagnosed UTI or US reports. We recommend renal isotopic scan and voiding cystography for serious presentation, high-risk factors, recurrence, and abnormal US. (4) Urological consultation is recommended: in urosepsis or obstruction, male infants < 6 months. Acute basal DMSA is recommended in congenital renal hypodysplasia. Six months post-infection, US and DMSA are recommended in severe pyelonephritis and vesico-ureteric reflux, where those with abnormal US or DMSA or both should have voiding cystography. (5) Follow-up recommendations include family orientation with hazards of noncompliance and monitoring at pregnancy. Conclusion Diagnosis and treatment show strong recommendations. Imaging depends on patient assessment. Referral to a pediatric nephrologist and urologist in complicated cases is crucial. Follow-up after the age of 16 years in adult clinics is important.

Background: Cardiovascular disease (CVD) is considered a major cause of death in renal insufficiency (RI). Contributing genetic factors is a recent focus of research. This study aims to elucidate apolipoprotein E (APO-E) and plasminogen activator inhibitor 1 (PAI-1) gene polymorphisms in RI children associated with CVD. Methods: We studied 50 cases with chronic kidney disease (CKD) associated with CVD, and 30 healthy controls. Study sample was grouped as one on conservative treatment, the second on hemodialysis and the third was posttransplant. PAI-1 and APO-E gene polymorphisms were investigated using allele-specific polymerase chain reaction (AS-PCR) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) respectively. Results: 4G4G and 4G5G were the most common PAI-1 polymorphism denoting high association of 4 G allele in renal insufficiency associated with CVD with absent link to dyslipidemia, echocardiography changes or thrombosis. E3E3 was the most common among APO-E polymorphism without relation to dyslipidemia or thrombosis. Dyslipidemia was significantly linked to thrombosis. The study confirmed the role of dyslipidemia and hemodialysis in promoting thrombosis. Conclusion: Although PAI 4G Genotyping did not show significant association with echocardiography severity or thrombotic severity, yet genetic expression for high levels of PAI in plasma is expected in response to CRI factors known to trigger its release, in addition to those related to dialysis. APO-E3E3 genotyping showed a significant association with echocardiography severity as it enhances APO-A which contributes to CVD. The current study confirmed a significant association between dyslipidemia and CVD; however, the prevalent patterns 4G and E3E3 did not show a significant association with dyslipidemia. The genetic role for APO-A, B, O, or even other isomers for APO-E should be further studied as well.

IntroductionImmunosuppressive agents are recommended for the management of children with steroid-resistant (SRNS), frequently-relapsing (FRNS), and steroid-dependent idiopathic nephrotic syndrome (SDNS). This study evaluated the efficacy of immunosuppressive agents in these cases.MethodsThis is a retrospective analysis of the records of 130 pediatric cases recruited from a tertiary-care center over a period of two years. They were divided into two groups: 51 patients with SRNS (Group I) and 79 cases with SDNS and FRNS (Group II). They were treated with immunosuppressive agents in addition to steroids, either as double- or triple-combination therapy. Complete or partial remission was considered a good response.ResultsIn group I, the proportions of good response to cyclophosphamide, cyclosporine A, and mycophenolate mofetil were 48.6, 60, and 80%, respectively (p = 0.162). In group II, the resistance rate was significantly higher with levamisole than with cyclophosphamide and azathioprine (p = 0.046). Leukopenia was reported infrequently after the administration of cyclophosphamide or azathioprine. The most serious adverse reaction was to cyclosporine A, which induced nephrotoxicity (6.4%), while no adverse effects related to levamisole were reported. Histopathological diagnoses were available in only 39 patients.ConclusionThe high potency of cyclosporine with steroids recommends its use in patients with idiopathic SRNS with a normal glomerular filtration rate. Its efficacy is augmented when combined with mycophenolate mofetil. Cyclophosphamide, orally or as intravenous boluses, together with alternate-day steroids, could be a good option outside the peripubertal age. The outcomes of FRNS and SDNS could be improved by encouraging compliance with the use of levamisole.
