IgA nephropathy journey — proteinuria almost in remission, eGFR dropped and then stabilized. Looking for long-term experiences.
Hi everyone,
I was diagnosed with IgA nephropathy after a kidney biopsy. My biopsy had a MEST score of M1 E0 S1 T0 and mentioned a perihilar variant.
My biggest concern has always been long-term progression and whether I'm at significant risk of ESRD.
My treatment and timeline
I initially had significant proteinuria, with UPCR reaching around 1.15 g/g.
I was treated with prednisolone 40 mg, which substantially reduced my proteinuria. I eventually tapered off steroids and stopped them in February 2026.
My current kidney-protective treatment includes:
Telmisartan
Dapagliflozin (Dapa) 10 mg
Finerenone (Kerendia) 20 mg
I started Kerendia after 9 May 2026.
Recent kidney function
My recent numbers:
2 Apr 2026: creatinine 1.11, eGFR 92
8 May: creatinine 1.21, eGFR 83
5 Jun: creatinine 1.39, eGFR 70
4 Jul: creatinine 1.40, eGFR 69.7
14 Aug: creatinine 1.40, eGFR 69.65
So there was a noticeable drop in eGFR from May to June, but since June my creatinine/eGFR have been essentially completely stable.
I'm wondering whether the initial decline could have been partly related to the combination of Dapa + finerenone + telmisartan, particularly because Kerendia was started after the May test.
Proteinuria/albuminuria
This is where things have become very encouraging.
My ACR was around 1015 mg/g in March 2025.
More recently:
4 Jul 2026: ACR 27 mg/g
14 Aug 2026: ACR 30.8 mg/g
Today's urine dipstick was negative for protein and blood, with 0 RBC/HPF and no casts.
Potassium is currently 4.4.
So currently I'm around:
eGFR ~70 + ACR ~31 mg/g + negative urine protein + no hematuria + stable creatinine.
I'm actually feeling quite positive about my future now.
I'd especially like to hear from people using Dapa + Finerenone
For anyone with IgA nephropathy who has used these medications, I'd really appreciate your experiences:
- Dapagliflozin (Dapa 10 mg):
How much did it reduce your proteinuria/albuminuria?
Did you experience an initial eGFR drop?
Did your eGFR stabilize afterward?
How long did it take before you noticed the full effect?
- Finerenone (Kerendia 20 mg):
How long have you been taking 20 mg?
Did it reduce your proteinuria/ACR?
Did you experience an initial creatinine rise/eGFR drop?
Did the effect persist over time?
Did your nephrologist increase you from 10 → 20 mg, and did you notice a difference after the increase?
- Combination therapy: For those taking Dapa + finerenone 20 mg + an ARB/ACE inhibitor, how effective has this combination been for your proteinuria?
I'm particularly interested in long-term real-world experiences, rather than just clinical-trial results.
Finally
For people who have had IgA nephropathy for 5–10+ years:
Does my current situation — eGFR around 70 but ACR around 30 mg/g and stable kidney function — look like a relatively favorable trajectory?
I'm obviously continuing regular follow-up with my nephrologist, but I'd love to hear from people who have been through a similar journey.
Thanks!
