A neglected case of renal tubular acidosis

Area of Science:

• Pediatric Nephrology
• Endocrinology
• Clinical Case Reports

Background:

• Distal renal tubular acidosis (dRTA) is a condition affecting kidney function, potentially leading to growth impairment and bone disease.
• Failure to thrive (FTT) and rickets are known complications of dRTA, impacting a child's development.
• Early diagnosis and intervention are crucial for managing dRTA and its associated symptoms.

Observation:

• A 6-year-old child presented with severe failure to thrive (weighing only 7.8 kg) and profound rickets.
• The patient exhibited unique physical and radiographic findings not typically seen in standard dRTA cases.
• The case involved a detailed four-year follow-up assessing treatment efficacy.

Findings:

• The child showed a notable response to treatment for distal renal tubular acidosis.
• Despite commonality of FTT in dRTA, the specific clinical presentation and radiological signs were distinctive.
• Long-term monitoring revealed the impact of therapeutic interventions on growth and skeletal health.

Implications:

• This case underscores the importance of recognizing atypical presentations of dRTA in children.
• Understanding unique findings can improve diagnostic accuracy and treatment strategies for pediatric renal tubular acidosis.
• The study contributes to the literature on managing complex cases of dRTA with severe failure to thrive and rickets.
