[Hormonal interactions and glucocorticoid receptors in patients with the nephrotic syndrome]
Insights
Thyroid dysfunction and low hormone levels are common in children with nephropathies, particularly renal dysplasia. This may explain resistance to glucocorticoid treatment in immune-related kidney diseases.
Area of Science:
- Pediatric Nephrology
- Endocrinology
- Internal Medicine
Context:
- Nephrotic syndrome in children presents with diverse clinical and pathological features.
- Thyroid status alterations are increasingly recognized in pediatric kidney diseases.
- Understanding these links is crucial for effective treatment strategies.
Purpose:
- To investigate the relationship between thyroid status and different variants of nephrotic syndrome in children.
- To identify specific thyroid function patterns associated with distinct nephropathies.
- To explore the role of thyroid hormones and steroid receptors in treatment resistance.
Summary:
- This study examined 27 children (6-15 years) with verified nephropathies, identifying four thyroid status variants in nephrotic syndrome: primary hypothyroidism, secondary hypothyroidism, low T3, and hypophyseal-thyroid dysfunction.
- Children with renal dysplasia showed low steroid receptors, thyroid hormones (T3, T4), and cortisol.
- The presence of immune glomerulopathy (glomerulonephritis, nephrotic syndrome) alongside these factors may lead to glucocorticoid treatment resistance.
Impact:
- Highlights the complex interplay between renal disease, thyroid function, and hormone receptor status in pediatric patients.
- Suggests potential biomarkers for predicting treatment outcomes in childhood nephrotic syndrome.
- Informs the development of targeted therapeutic approaches for refractory cases.
Abstract:
As many as 27 children aged 6 to 15 years with morphologically verified nephropathies were examined. Four variants of changes in the thyroid status, characteristic of children with different variants of nephrotic syndrome were distinguished: 1) biochemical signs of primary hypothyroidism, 2) biochemical signs of secondary hypothyroidism, 3) low content of T3, 4) dysfunction of the hypophyseal and thyroid system. It is shown that the low level of steroid receptors, thyroid hormones that the low level of steroid receptors, thyroid hormones (T3 and T4) and cortisol is typical of children with the signs of renal dysplasia. It is assumed that superaddition under such conditions of immune glomerulopathy (glomerulonephritis and nephrotic syndrome) gives rise to the resistance to the treatment with glucocorticoids.
