|a Objective: To evaluate the effectiveness and safety of treatment with Burosumab in pediatric X-linked hypophosphatemia (XLH) patients. Methods: In this retrospective case study, 4 children with pediatric XLH, who were treated with Burosumab in Beijing Children's Hospital, Capital Medical University and Shandong Provincial Hospital affiliated to Shandong First Medical University from July 2022 to December 2023, were selected as the study objects. We collected and analyzed their clinical characteristics, biochemical indicators, imaging results, and treatment. The children were followed up every 3 months until December 2023, and the clinical outcomes and adverse drug reactions after treatment were evaluated. Results: Of the 4 patients, 3 were males and 1 was female; they were aged 6.7, 2.9, 2.1, and 2.3 years, respectively. Three patients had previously received treatment with phosphate supplements and active vitamins, but their wadding gait and lower limb deformities did not improve significantly, neither did their imaging changes of active richets. The initial dose of Burosumab in the 4 patients was 0.8 mg/kg, administered subcutaneously every 2 weeks, with a treatment course of 0.8-1.3 years. The fasting serum phosphorus and tubular maximum reabsorption of phosphate/glomerular filtration rate (TmP/GFR) of the 4 patients before treatment were 0.72, 0.95, 0.81, 0.66 mmol/L and 0.67, 0.85, 0.87, 0.61 mmol/L, respectively. At the last follow-up, the fasting serum phosphorus and TmP/GFR levels were significantly increased (0.96, 1.09, 1.09, 0.90 mmol/L, and 0.85, 0.79, 1.03, 0.98 mmol/L, respectively). Among them, only the TmP/GFR level (1.17 mmol/L) in case 2 achieved normal values at 3 months post-therapy, while the rest did not reach the normal range for children of the same age. After treatment, the alkaline phosphatase levels of all patients gradually decreased (the values were 461, 240, 423, and 237 U/L, respectively), and the ALP levels in cases 2 and 4 returned to normal at the last visit. Case 4 showed a slight increase in parathyroid hormone (PTH) levels after 9 months of treatment, while the PTH levels in the rest 3 cases remained normal. Case 1 underwent a 6-minute walking test, and the walking distance increased from 245 m to 570 m. Abnormal gait, lower limb deformity, and the severity of rickets in the 4 patients had all improved. No adverse drug reactions such as nephrocalcinosis, local skin injection reaction, hyperphosphatemia, or vitamin D deficiency were observed. Conclusion: Burosumab can improve clinical symptoms in children with XLH with a good safety profile
