[Detection of urate tubulointerstitial nephritis: contribution of diagnostic questionnaire]
Aim:
To develop a diagnostic questionnaire to identify individuals with uric acid hyperproduction and risk of urate tubulointerstitial nephritis (UTIN).
Materials And Methods:
Clinical symptoms of 650 patients with verified hyperuricemia or hyperuricosemia have been summarized to design a special questionnaire which will be able to identify subjects to whom test for uricemia and uricosuria may be recommended to prevent onset and/or progression of UTIN.
Results:
The questionnaire has been compiled which has rather high sensitivity and specificity in identification of persons with hyperuricemia and/or hyperuricosuria at risk to develop UTIN.
Conclusion:
The designed questionnaire allows to select subjects with existing UTIN or at UTIN risk both in population and individual studies.
