We report a rare case with multiple renal infarction associated with lupus anticoagulant and SLE. A 20-year old woman presented with remitent fever, butterfly rash and, abdominal pain. Laboratory findings showed leukopenia, positive antinuclear and anti-DNA antibodies, and biological false positive for syphilis. Despite a therapy with prednisolone 25 mg/day, the patient showed hypocomplementemia, high titer of anti-DNA antibody and a development of proteinuria and an elevation of serum creatinine. Renal biopsy revealed no abnormalities. She presented abdominal pain with an elevation of serum LDH. Abdominal dynamic computed tomography demonstrated multiple perfusion defects in both kidneys indicating multiple renal infarction. Brain MRI showed multiple micro infarction in the anterior lobes. She was treated with 80 mg of aspirin and have been in remission for two years. Although there have been reported 18 cases with renal infarction associated with antiphospholipid syndrome, this is the first report in Japan. Renal infarction should be differentiated from renal involvement in patients with SLE who have antiphospholipid antibodies.

Rizatriptan and zolmitriptan are both used to relieve acute migraine and cluster headaches. The mechanism of action is similar to the other triptans, in that they reverse abnormal cerebral vasodilation through their activity as 5-HT1B receptor agonists. Triptan-induced vasoconstriction is attributed to its activity on peripheral 5-HT1B receptors and has rarely been reported to result in stroke, myocardial infarction and ischemic colitis. We present two cases of renal infarction associated with therapeutic triptan use. The first patient is a 57-year-old man with a history of hypertension that was well controlled on valsartan and hydrochlorothiazide. He was recently diagnosed with cluster headaches and was treated with indomethacin, prednisone, butalbital-acetaminophen-caffeine and hydrocodone without relief. He then received two therapeutic doses of rizatriptan on each of the two days prior to presentation. Subsequently, he presented to the emergency department complaining of nausea, vomiting and right-sided abdominal pain. A computerized tomography (CT) scan of the abdomen and pelvis with intravenous contrast revealed a very large wedge shaped infarction of the right kidney. The second patient is a 34-year-old man with a past medical history significant only for life-long migraine headaches successfully treated for the past six years with zolmitriptan. Shortly after taking one therapeutic dose of zolmitriptan, he presented to the emergency department complaining of nausea and left-sided abdominal pain. A CT scan of the abdomen and pelvis with intravenous contrast revealed multiple wedge-shaped infarctions of the left kidney. Renal infarction was confirmed in both patients by arteriogram of the renal arteries. Although both rizatriptan and zolmitriptan are effective in the treatment of migraine and cluster headaches, they may induce peripheral vasospasm leading to renal infarction.

Renal infarction is caused by profound hypoperfusion secondary to embolic/thrombotic occlusion of the renal artery or vasospasm of the renal artery. We present a case of a 54-year-old patient who presented with nausea, vomiting, and vague abdominal pain. He had frequent episodes of migraine headaches and he treated himself with as needed rizatriptan. CT scan of the abdomen showed renal cortical infarction. After extensive investigations, etiology of his renal infarct was deemed to be due to rizatriptan.

Renal infarction is a rare clinical entity that is not easily detected by low-sensitivity ultrasound. We herein report a case of dermatomyositis with renal infarction detected during corticosteroid therapy. The patient was followed up for 18 months. A woman who was clinically diagnosed with dermatomyositis complained of severe pain in the right flank of the low back and abdomen, accompanied by nausea and vomiting during corticosteroid therapy. Based on the findings of routine blood tests, abdominal X-ray radiography, and abdominal ultrasound, the patient was diagnosed with acute gastroenteritis and treated with levofloxacin. However, her symptoms were not relieved. Abdominal contrast-enhanced computed tomography revealed renal infarction. Clinicians should be alert to the occurrence of thrombosis, especially when it manifests as vasculitis in patients with rheumatic disease who complain of severe abdominal pain, because it may suggest the presence of renal infarction.

Renal infarction is relatively a rare condition that is often linked to the presence of underlying cardiac disease such as atrial fi brillation and valvular heart disease. While the classic presentation of renal infarction includes persistent abdominal or loin pain with high serum levels of lactate dehydrogenase (LDH), microscopic hematuria and high C-reactive protein (CRP), patients can present without these features. It is important to have high index of suspicion for this condition in patients who present with unexplained back or abdominal pain, even if there are no known traditional risk factors. Herein, we describe the case of a 42-year-old man who presented with abdominal pain and found to have acute right and subacute bilateral renal infarcts. No cause was identifi ed despite exhaustive work up. Interestingly, his urinalysis, LDH and CRP were within normal limits.
