Most patients with thin basement membrane disease are incidentally discovered to have [[microscopic hematuria]] on [[urinalysis]]. The [[blood pressure]], [[kidney function]], and the urinary protein excretion are usually normal. Mild [[proteinuria]] (less than 1.5 g/day) and [[hypertension]] are seen in a small minority of patients. Frank [[hematuria]] and loin pain should prompt a search for another cause, such as  [[kidney stone]]s or [[loin pain-hematuria syndrome]]. Also, there are no systemic manifestations, so presence of [[hearing impairment]] or [[visual impairment]] should prompt a search for [[hereditary]] nephritis such as [[Alport syndrome]].
*New onset [[hypertension]].
*[[Proteinuria]].
*[[Renal impairment]].
*[[Renal failure]].


Thin basement membrane disease must be differentiated from the other two common causes of [[glomerulus|glomerular]] [[hematuria]], [[IgA nephropathy]] and [[Alport syndrome]]. The history and presentation are helpful in this regard:
*In [[Alport syndrome]], there is often a family history of [[kidney failure]], which may be associated with [[hearing impairment]]. Also, males tend to be more affected as Alport syndrome it is [[X-linked]] in most cases.
*In [[IgA nephropathy]], episodes of frank [[hematuria]] are more common, and a family history is less common.

Overview

Obtaining complete history both for the patient and family is an important aspect of diagnosing TBMD. The hallmark of TBMD is benign hematuria. A positive family history of incidental finding of intermittent or persistent hematuria is suggestive of TBMD. TBMD is mostly asymptomatic. Microscopic hematuria is found incidentally.

History and Symptoms

History

Obtaining complete medical and family history is an important aspect of diagnosing TBMD. It provides insight to cause and differentiation of TBMD with Alport syndrome, IgA nephropathy, Lupus Nephritis and other glomerulopathies. History may be obtained focusing specific areas including:

Symptoms

TBMD is mostly asymptomatic. The following signs are included:
