RESUMO
Nutrition in paediatrics has always been one of the most important factors for optimal growth. Children with chronic kidney disease (CKD) need special consideration for better long-term outcomes, including nutritional status, optimal height, and cognitive function. Nonetheless, there are many obstacles to overcome to attain optimal linear growth and nutritional status in children with CKD. This review highlights the need for tools to assess the growth parameters in CKD. In addition, recommendations for dietary intake play a major role in controlling electrolyte disturbances in patients with CKD. For example, it is still unclear whether it is better to restrict phosphate sources in inorganic, organic, or food additives. The review also summarises different factors such as fluid intake, route of feeding, and essential nutrients that require particular attention in paediatric patients with CKD. In summary, a multidisciplinary team is needed to devise individual nutritional plans to achieve the best outcome and improve the quality of life of patients.
RESUMO
Background Acute lymphoblastic leukemia (ALL) is an invasive cancer that results from the malignant conversion and rapid replication of white blood cells and hematopoietic stem cells that supply multiple lymphocytes. Harmful gene mutations occur in more than two-thirds of patients with ALL; however, these mutations have not been extensively identified in Saudi Arabia. Aim The aim of this study was to identify the types of mutations in patients with ALL at King Abdulaziz University Hospital (KAUH) in Jeddah. In addition, we identified the most common mutations. Methods A retrospective study was performed on patients who were diagnosed with ALL from January 2009 to January 2019 at the Department of Hematology at KAUH. Our target population comprised patients diagnosed with ALL, including all age groups and both sexes. Patients were excluded if they had Down syndrome or central nervous system involvement, Li-Fraumeni syndrome, or neurofibromatosis. Results Of the 130 patients with ALL, 101 (77.77%) were children. The number of men (n=81) was substantially more than that of women (n=49). The data showed that 13.1% of our patients had mutations, and they occurred more frequently in patients with B-cell lymphoblastic ALL (B-ALL) than in those with T-cell lymphoblastic ALL (T-ALL). Several mutations, including BCR-ABL and ETV6/RUNX1, were more common in B-ALL, whereas the MLL-F0X04mutation was more commonly observed in T-ALL. There was a significant difference between the types of ALL and the genes involved (p=0.039). One female patient had translocation t(X;11)(q26;q23) (MLL-F0X04), which is a rare mutation. Conclusion In summary, 13.1% of our study population had mutations. The BCR-ABL fusion gene was the most frequent mutation in patients at KAUH, and it occurred at a higher rate in B-ALL. Moreover, we detected other mutations, such as ETV6/RUNX1 and MLL-F0X04. The gene mutations were significantly different between B-ALL and T-ALL.
