A historical review and the present author's study on
diabetic nephropathy
have been presented. Three characteristic lesions in KW-lesion, namely nodular, exudative and doughnut lesion may all be regarded as to be caused by severe circulatory disturbance occurring in intraglomerular branches of the afferent artery. This circulatory disturbance is considered to be brought about by sudden
spasm
of the peripheral portion of the afferent branches. The diffuse form of Bell may be regarded as to be a slighter type without severe mesangiolysis. Arteriolar hyalinosis and arteriosclerosis and/or atherosclerosis may be caused by intraglomerular circulatory disturbances. The most important problem in
diabetic nephropathy
, including KW-lesion and Bell's diffuse form, is to elucidate the mechanism leading to the occurrence of
spasm
of the peripheral portion of intraglomerular afferent branches. Becker found fixation of antiactomyosin-antibody in the mesangial tissue by the immunofluorescent method. Many studies along this line have been made, but none are adequate in fully explaining the mechanism involved.

To evaluate the secretion of vasoactive factors in vascular endothelium of patients with non-insulin-dependent diabetes mellitus (NIDDM) the authors examined 31 NIDDM patients. Of them, 18 had no signs of renal involvement, 13 patients showed apparent
diabetic nephropathy
(DN). In the former patients the blood contained much greater content of vasodilating factor prostacyclin than of vasoconstricting factor endothelin-1 (ET-1) and thromboxan A2 (TxA2). In
diabetic nephropathy
the balance of vasoactive factors shifted to predominance of vasoconstrictors ET-1 and TxA2. Such rearrangement of vasoactive factors to higher quantities of vasoconstrictors in diabetes mellitus may initiate or promote progression of
diabetic nephropathy
with resultant
spasm
of afferent glomerular vessels, reduced glomerular filtration and renal blood flow rates, arterial hypertension, increased thrombogenesis. Thus, elevated levels of ET-1 and TxA2 in diabetics and their rise with progression of
diabetic nephropathy
are likely to act as pathogenetic factors underlying onset and progression of nephroangiopathy.

A 54-year-old male with chronic renal failure due to
diabetic nephropathy
suffered dysphagia and left facial
spasm
without head trauma during a hemodialysis session. CT scan revealed a right acute epidural hematoma. MRI and cerebral angiography did not reveal any abnormalities in the intracranial vasculature. The occurrence of intracranial spontaneous epidural hematoma in a haemodialysis patient has not been reported. During hemodialysis, the intracranial pressure transiently increases and rapidly recovers. It is assumed that the decreasing intracranial pressure caused epidural hematoma.
