Antiphospholipid syndrome (APS) is a cause of infertility and fetal loss. Ovarian stimulation can induce previously unknown APS. Ovarian hyperstimulation syndrome (OHS) is uncommon but potentially life-threatening, as well as catastrophic APS. A woman that simultaneously developed a severe OHS and a catastrophic APS is described in this paper. Both entities produced thrombotic cardiac and brain thrombosis. A peculiar mechanism of cardiac ischemia is also described. In spite of the life-threatening risk of this situation, the indication for preventive anti-aggregation and/or anticoagulation is not clear.

In this case, we describe a 33-year-old man presenting with acute mesenteric ischemia. When we searched for a source of embolism, a giant right atrial mass and patent foramen ovale was discovered. Standard electrocardiography showed signs of an old, silent anteroseptal wall myocardial infarction, confirmed by echocardiography and left ventriculography. Coronary angiography revealed complete occlusion of the left anterior descending artery. The diagnosis of primary antiphospholipid syndrome was confirmed by anticardiolipin antibodies test. Surgical myocardial revascularization along with the resection of the mass and the closure of the patent foramen ovale were performed. Histological examination of the operative specimen showed a thrombus. This is the first reported case presenting with acute paradoxical mesentery embolism accompanying an old myocardial infarction in a young patient with primary antiphospholipid syndrome.

It has been widely accepted that the antiphospholipid syndrome (APS) is an autoimmune hypercoagulability syndrome in which a variety of venous and arterial thrombotic events may occur. Peripheral obliterating arterial disease characterized by aortoiliac steno-occlusion occurring in young women, is reported in the literature under the name of Small Aorta Syndrome (SAS). Although it remains unclear whether SAS represents a separate entity, the small size of the distal aorta increases the risk for aortoiliac occlusive disease. A 41-year old white woman was admitted with acute digital ischemia of the left foot. She had positive lupus anticoagulant and IgG anti-cardiolipin antibodies (61 UI/mL), but antinuclear antibodies and anti-ds-DNA antibodies were negative. She previously had two deep venous thromboses of the legs and, despite the oral anticoagulant therapy, pulmonary embolism occurred. Shortly thereafter, abdominal angio-magnetic resonance imaging suggested that the infra-renal aorta was narrowed more than 50%, without thrombotic occlusion of the terminal aorta and common iliac arteries. These findings were compatible with the features of SAS. There were no atherosclerotic changes in the artery wall and no other prediposing risk factors such as smoking, oral contraceptive or hyperlipidemia. After adequate anticoagulation and intravenous prostacyclin treatment the patient's symptoms and the ischemic lesions improved markedly. To our knowledge this is the first report of the association of SAS and primary APS. The occurrence of SAS in patients with APS may dramatically increase the risk of trombothic events.

The presence of anticadiolipin antibodies (aCL) has been associated with vascular occlusive events. However, the role of aCL in predicting ischemic events, particularly ischemic stroke, is controversial. In order to determine if aCL is either associated with thrombotic disease or with an increased risk of recurrent stroke or thrombotic events, we performed a prospective study on a cohort of Romanian patients with stroke that were tested for aCL. We studied the prevalence of cardiovascular risk factors in the two subgroups (aCL positive or aCL negative) considering the age of patients and the medical evolution in the first 12 months after the index stroke. Globally, neither the antecedents of thrombotic events or abortions, nor the clinical or biological profile or the recurrence of vascular events showed any significant difference between the group with or without aCL. Only in two patients the criteria for antiphospholipid syndrome were fulfilled. In 37% of cases, there was a variability of aCL positive titers at 8 weeks after the index event. This raised the necessity to isolate a subpopulation with higher risk of ischemia in the presence of aCL, and the need of more specific subtypes of antiphospholipid antibodies as a marker of thrombophilia.

Polyarteritis nodosa (PAN) is a vasculitis of small- and medium-sized vessels, characterized by vascular aneurysms that can lead to ischemia and infarction. We present the case of a patient with classic polyarteritis nodosa in abdominal organs who additionally demonstrated antitreponemal and antiphospholipid antibodies, resulting in a severe cerebral thrombosis. This case highlights: 1. The potential for false-positive syphilis serology in PAN patients, and 2. The rare coexistence of polyarteritis nodosa and the catastrophic antiphospholipid syndrome.

Intestinal ischemia in antiphospholipid antibody syndrome (PAPS) could be due to arterial thrombosis from hypercoagulability. A male patient, 45 years old, was admitted to the hospital with symptoms of acute abdomen and after laparotomy he developed sepsis, right kidney infarction, jejunal ischemia, aortic thrombosis, wide necrosis of both gluteus muscles, left subclavian vein thrombosis. Our therapeutic and diagnostic strategy was delineated after demonstration of antiphospholipid antibodies. The patient was treated with total parenteral nutrition in the presence of 5 enteric fistulas with very high outflow, arterial stent insertion and daily changes of medicated dressings. Outcome was excellent with small residual deficit in walking. Continuous nutritional status monitoring and very high nitrogen supply allowed excellent healing of huge wounds and closure of enteral fistulas.

Spontaneous native aortic valve thrombosis is an uncommon event occurring after heart valve disease, during cardiac catheterization, bacterial endocarditis, or as a hypercoagulative state as in antiphospholipid antibody syndrome. We report the case of a 55-year-old woman in whom thrombi developed on a native aortic valve with no predisposing cause. The thrombi were responsible for recurrent lower limb ischemia. Eighteen months after aortic valve replacement, the patient is doing well.

Catastrophic antiphospholipid syndrome (CAPS), described by Asherson in 1992, is a rare form of antiphospholipid syndrome resulting in multiorgan failure with a mortality rate of about 50%. The syndrome occurs in patients with either systemic lupus erythematosus and other rheumatic diseases (systemic sclerosis, rheumatoid arthritis, primary Sjogren syndrome) or alone. Whereas in "classic" antiphospholipid syndrome (APS), medium-large vessels are involved, a diffuse small vessel ischemia and thrombosis (microangiopathic disease) leading to a severe multiorgan dysfunction is predominant in CAPS. "Trigger" factors have been demonstrated in 45% of patients, but in the majority, they remain unknown. Not infrequently, CAPS arises in patients without any previous thrombotic history. The kidney is the organ most commonly affected, followed by the lung, the central nervous system, the heart and the skin. Disseminated intravascular coagulation occurs in approximately 13% of patients. The present study reports the clinical and serological features of 4 patients affected by this rare form of antiphospholipid syndrome. Nephrologists should be aware of the possibility of this syndrome as a cause of multiorgan failure since prompt recognition is essential for effective treatment.

Systemic sclerosis (SSc) patients typically experience Raynaud phenomena that is often complicated by digital ischemic lesions, gangrene, and digital loss. Other causes of peripheral ischemia, such as atherosclerosis, cryoglobulinemia, antiphospholipid syndrome, myeloproliferative disorders, paraneoplastic syndromes, and hyperadrenergic endocrine conditions, may be masked in SSc patients. We present a woman with limited SSc who developed toe necrosis and acute coronary events as a complication of a previously undiagnosed pheochromocytoma.

The association of the antiphospholipid syndrome with malignancy has been extensively reported. Raynaud's phenomenon has also been reported to be associated with various malignancies. In this report, we describe two patients who presented with severe digital ischemia mimicking Raynaud's phenomenon. The patients were found to have antiphospholipid syndrome, and upon extensive evaluation, a diagnosis of a malignancy was made. This report highlights the importance of malignancy workup in patients with severe digital ischemia associated with antiphospholipid syndrome.
