What Causes SRNS in Children?
The exact cause of SRNS in children is often not well understood, but it is believed to be associated with genetic mutations, especially in genes related to the function of podocytes, the cells in the kidney that filter blood. Other potential causes include
immune system dysregulation and secondary conditions like infections or exposure to toxins.
How is SRNS Diagnosed?
Diagnosis of SRNS typically involves a combination of clinical evaluation, laboratory tests, and possibly a
kidney biopsy. Initial diagnosis may involve the use of steroids to see if there is any response. If there is no response after an adequate trial period, the condition is classified as steroid-resistant. Additional tests may include genetic testing to identify any underlying mutations.
What are the Symptoms of SRNS?
The primary symptoms of SRNS are similar to those of other forms of nephrotic syndrome, including severe
proteinuria (excess protein in the urine), hypoalbuminemia (low levels of albumin in the blood), edema (swelling), and hyperlipidemia (high levels of fats in the blood). Because SRNS does not respond to steroids, these symptoms persist despite treatment.
What are the Treatment Options for SRNS?
Treatment for SRNS often involves a multi-faceted approach. Immunosuppressive drugs like
calcineurin inhibitors (e.g., cyclosporine, tacrolimus) and other medications such as mycophenolate mofetil or rituximab may be used. Supportive treatments focus on managing symptoms and may include diuretics for edema, ACE inhibitors or ARBs for proteinuria, and statins for hyperlipidemia.
What is the Prognosis for Children with SRNS?
The prognosis for children with SRNS can vary widely. Some children may respond to alternative immunosuppressive therapies, while others may progress to chronic kidney disease and require
renal replacement therapy, such as dialysis or kidney transplantation. Early and aggressive treatment is crucial for improving outcomes.
Are There Any Preventive Measures?
Currently, there are no specific preventive measures for SRNS due to its often idiopathic nature. However, early diagnosis and treatment, along with genetic counseling for families with a history of nephrotic syndrome, can help manage the condition more effectively.
How Can Families Support a Child with SRNS?
Families can provide crucial support by ensuring adherence to medication regimens, attending regular follow-up appointments, and maintaining a balanced diet as advised by healthcare providers. Emotional and psychological support is also essential, as chronic illness can be challenging for both the child and family members.
What is the Role of Research in SRNS?
Ongoing research is vital for better understanding and managing SRNS. Studies focus on identifying new genetic mutations, developing novel therapies, and improving existing treatment protocols. Participation in clinical trials may also be an option for some patients, providing access to cutting-edge treatments.
