Dear Sir, My daughter twisha age 5 was suffering from acute nephritis at age of 3. she was on steroids then. she recovered from the same in 6 months. she went in to relapse after 6 months but recovered in 3 weeks. later there were no issues and she was normal. now for past 4 months she is regularly getting few symptoms as seen at age of 3 like swollan eyes, aulbumin varys from plus one to plus four. I have shown here to child specialist as well as nephrologist. she has under gone various test for kidney such as sonography, dsma scan, urine creatin ratio, blood tests etc. she showns symptoms and then goes back to normal. this is being happening for last 3 months. Doctors are not able to judge the cause. all reports show that kidney is normal, but cause is not yet traceable. Request to guide us on the issue as we are very much concern about her.

### output:

Hi, If I were your treating Doctor for this case, I would come up with three possibilities, these include:1. The first possibility is B-hemolytic Streptococcus of group A. Diagnosis can be confirmed by test for Antistreptolysin-O, then she also will be required throat culture and sensitivity to antibiotics and consulting of ENT .2. The second possibility is herpes persistent infection. IGM, G to HHV 6 type, CMV, EBV should be measured to rule out any herpes.3. Hereditary, consult genetic doctor. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
