किडनी ट्रांसप्लांट के बाद बढ़ते क्रिएटिनिन लेवल के बारे में क्या करें?

A gradual increase in creatinine levels alongside a decrease in eGFR can certainly raise concerns post-kidney transplant. Yes, tacrolimus toxicity is a potential cause for such changes even if a Doppler ultrasound appears normal. Tacrolimus can lead to nephrotoxicity, often visible as subtle changes in kidney function before any structural abnormalities are detectable via imaging. Monitoring tacrolimus trough levels would be sensible; elevated levels might necessitate dose adjustment. Declining eGFR and rising creatinine warrant close attention; it’s not uncommon but could point towards chronic changes, possibly related to medication or underlying chronic rejection, among other factors. Kidney biopsy becomes more pertinent if there is unexplained or significant deterioration in kidney function despite stable drug levels, normal imaging, and lack of any reversible causes like dehydration or infection. Speaking of dehydration, it’s a significant consideration. Ensuring adequate hydration is crucial as chronic mild dehydration can stress the transplanted kidney. Before considering biopsy, comprehensive lab work should include tacrolimus trough levels, complete metabolic panel, and potentially donor-specific antibody testing to assess for immune-mediated injury. It might also involve review of blood pressure control, any recent infections, dietary factors, and medication adherence. If these evaluations don’t reveal clear causes and creatinine continues to rise, a biopsy could help assess for subclinical rejection or medication effect. Engaging closely with your nephrologist is essential for timely interventions and optimal management.
