Background: Knowledge of pulmonary complications (PCs) in children after hematopoetic stem cell transplantation (allo-HSCT) is limited; most data are from adult studies. Case: We describe a 8 year old girl with high risk acute myeloid leukemia who developed graft versus host disease (GVHD) on Day 20, Cytomegalovirus (CMV) pneumonia on Day 50 and Cryptogenic organizing pneumonia (COP) on Day 170 after allo-HSCT. Discussion: Cryptogenic organizing pneumonia is a rare noninfectious PCs that can be idiopathic or have several risk factors as a secondary causes, such as viral respiratory infections, drugs, GVHD and allo-HSCT. Viral respiratory infections and alloimmune lung syndromes have been reported in a few patients who have undergone transplantation. Conclusion: Transplant physicians should be kept in mind for the development of alloimmune lung syndrome in the form of COP following CMV pneumonia in patients after allo- HSCT

Background: Pure red cell aplasia is characterized by anemia, reticulocytopenia and diminished bone marrow erythroid precursors. It has multifactorial etiology and consequently several therapeutic interventions. Case: In August 2017, a young patient was diagnosed to have pure red cell aplasia. She was given immunosuppressive therapy for approximately two months but this treatment was stopped due to intolerance. Later on she developed herpes zoster infection that was treated with valacyclovir. Subsequently, it was noted that the patient became blood transfusion independent due to normalization of her hemoglobin and regeneration of the erythroid precursors in the bone marrow. Discussion: Varicella zoster virus behaves differently from other members of the herpes group of viruses such as cytomegalovirus and Epstein-Barr virus. Two retrospective studies, performed in patients with malignant hematological disorders and bone marrow failure, have shown that infection with the virus may cause stimulation of the three cell lines in the bone marrow and superior overall survival. Conclusion: The outcome of the patient presented confirms the findings of the two studies showing long-term beneficial effects of varicella zoster virus infections in immunocompromised individuals.

Introduction and aim: Idiopathic nephrotic syndrome (INS) is the most common type of this disease during childhood. Minimal change nephrotic syndrome (MCNS) is the most common histopathological lesion (80 – 90%) of INS in children and about 90% of patients are steroid responsive, while congenital nephrotic syndrome is disorder that may be caused by several diseases. Intrauterine infections, especially CMV infection, have frequently been incriminated as etiological factors of secondary CNS. The aim of this research was to evaluate the frequency of CMV infection children with active nephrotic syndrome in our pediatric nephrology unit Patients and methods: This descriptive (cross sectional) study was conducted in pediatric nephrology unit, Zagazig University Hospitals and included 60 patients WITH NS in activity; Participants were subjected to, Full history taking, Clinical examination; general & local, Routine laboratory investigations and Serum samples were tested for HCMV specific immunoglobulin G (IgG) and immunoglobulin M (IgM) using ELISA Kit. Results: We found 100% of cases were IgG positive and 7/60 cases were IgM positive, There were no statistically significant differences between IgM positive-patients vs IgM-negative patients according to age, sex and first attack or relapsed NS, There were statistically significant differences between IgM positive-patients vs IgM-negative patients in blood laboratory data in decreases in HB (P=0.024) and serum urea nitrogen (P=0.04) Conclusion: We concluded that serofrequency of cytomegalovirus infection in pediatric nephrology unit, Zagazig university hospitals during follow-up was 12% for cmv IgM and 100% for cmv IgG at ns children patients

Targeted screening for Cytomegalovirus (CMV) in Deaf and Hard of Hearing (DHH) children is now internationally recommended. With newborn genomic screening for DHH children a future possibility, the commercially-available human genomic DNA collection kit (ORACollect, Oragene OCR-100) could enable one single sample to screen for CMV and genetic causes of deafness at scale with minimal additional costs. Our pilot study validated ORACollect against Copan FLOQswabs® (gold standard clinical procedure) for detecting CMV using 15 sets of saliva samples from 14 infants/children, comparing CMV PCR results using different testing protocols. ORACollect stored at room temperature had high sensitivity (up to 89%), specificity (up to 80%) and percent agreement (up to 86%) in detecting CMV DNA compared to FLOQswabs®. This suggests that ORACollect is an appropriate alternative to FLOQswabs® for collecting viral CMV DNA for PCR testing, independent of the DNA extraction approach. This could be revolutionary in facilitating dual genomic and viral screening in newborns and would enable CMV screening in non-tertiary hospital settings where laboratory facilities are not available.
