@entity226 ( @entity226 ) is traditionally considered to spare the kidney, although an uncontrolled study reported microscopic haematuria in 10 out of 30 @entity1 with @entity226 . To study the frequency and the characteristics of microscopic haematuria in @entity226 , we retrospectively studied 42 @entity1 with biopsy-proven @entity226 , 39 @entity1 with @entity2760 rheumatica (PMR) and 62 control @entity1 >or=60 years of age, admitted to the general internal medicine unit. @entity1 with @entity4658 , significant @entity793 or a known @entity74 were excluded. Microscopic haematuria was defined as the presence of >5 red blood cells (RBC) per high-power field (sediment counts) or of >8 RBC/microl (direct counting). Microscopic haematuria was present at presentation in 47.6% of the @entity226 @entity1 , versus 17.9% of the PMR @entity1 (P = 0.005) and 21.0% of the control @entity1 (P = 0.008). Urinary RBC were predominantly dysmorphic in all @entity226 @entity1 in whom RBC morphology was assessed (n = 7). Presenting symptoms, @entity551 and degree of leukocyturia did not differ significantly between @entity226 @entity1 with or without haematuria. After the initiation of corticosteroid therapy, microscopic haematuria was no longer detectable in 25 of 35 @entity226 @entity1 (71.4%). Microscopic haematuria of renal origin is frequent but generally benign in @entity1 with @entity226 . Its presence, if unassociated with blood pressure elevation or renal function deterioration, helps to rule in rather than to rule out the diagnosis of @entity226 . In the typical setting invasive urologic and nephrologic work-up may not be warranted.
