<s>[INST] My sister was told she has idiopathic cryoglobulinemia. She has been treated for 9 months for glomerulonephritis membranoproliferative. How could they have mis-diagnosed this? She was on cancer & steriods for months which now they say damaged her kidneys. Is there hope for her to be cured of this? [/INST] HIWell come to HCMI really appreciate your concern, misdiagnosed is happens some time because doctor is after all human beings, it is not the single factor that cause this and it is not possible to discuss it here if this is the chronic renal condition then it can be well manageable even it not cured    hope this information helps. </s>
