The clinical significance of lupus non-inflammatory necrotizing vasculopathy (NINV) is not well established. For example, since lupus renal NINV is usually reported to coexist with proliferative and active glomerulonephritis, it is difficult to demonstrate the role of NINV on renal pathophysiology. Here we report a 16-year-old SLE boy with renal NINV presenting as ischemic glomerulopathy and small vessels-related ischemic heart failure. The renal biopsy demonstrated mild proliferative glomerulonephritis and NINV initially, and one month later repeated renal biopsy showed NINV with ischemic glomerulopathy. These findings established that NINV, but not proliferative glomerulonephritis, was responsive for his acute renal failure (ARF). Another interesting question is about the pathophysiology of his myocardial dysfunction. This patient presented typical angina and congestive heart failure (CHF). Echocardiograms and ventriculography revealed dilatation of four chambers and low ejection fraction. Serial electrocardiograms demonstrated evolutionary ischemic changes. Coronary angiography revealed no abnormality of large vessels. These findings suggested small vascular lesions-induced myocardial ischemia was the underlying mechanism of dilated cardiomyopathy. As myocardial biopsy was not done in our case, we could only speculate, but not prove, that the NINV observed in renal biopsy may also involve in cardiac microvascular beds. Nevertheless, this interesting case emphasized the role of obliterative small vascular lesions in the pathophysiology of ARF and myocardial dysfunction. The patient was treated with high-dose corticosteroid, plasma infusion and hemodialysis. His cardiac function improved gradually, however the renal function did not recover.

A 41-year-old woman presented with acute angina in the emergency unit. Additionally, she reported pain in both legs and a weight loss of 5 kilograms within the last 10 days. ECG revealed an acute anterior myocardial infarction. However, immediate coronary angiography showed open arteries with minimal arteriosclerosis. A characteristic rise of cardiac enzymes together with an akinesis of the anterior wall and an adjacent mural thrombus was highly suggestive of a transient coronary thrombosis. Further investigations showed occlusion of multiple arteries in both legs and a splenic infarct. Although there was a typical risk profile including smoking, hyperlipidemia and regular estrogen medication, a further work-up was started. Urin analysis was decisive for the presence of proteinuria and a severe nephrotic syndrome. The definite diagnosis was made by direct biopsy of the kidney that revealed the characteristic findings of a minimal change glomerulopathy. Rapid remission could be induced by high-dose oral steroids. During routine work-up of coronary syndromes, especially in those with normal coronaries, rare but treatable causes of myocardial infarction and coagulopathy have to be thought of and should carefully be excluded.
