It should be noted that potassium levels remained low until 66 days of life with values of 3.1 mmol/L (Figure 1).

Finally, at 115 days of life, there were still signs of proximal tubulopathy with glycosuria, tubular proteinuria and loss of phosphorus and sodium and the need for supplementation (oral sodium at 5 mEq/kg/day and phosphate at 2 mEq/kg/day) (Figure 2).
