A 61-year-old Japanese woman with both Takayasu's arteritis (TA) and systemic lupus erythematosus (SLE) presented with proteinuria due to glomerulopathy associated with podocytic infolding. She presented with unequal pulses in the upper extremities at 38 years old. TA was diagnosed on the basis of angiographic identification of stenosis in the left subclavian artery. Eight years after onset of TA, SLE was diagnosed on the basis of clinical and laboratory findings, including proteinuria, hematological and immunological abnormalities, high titer of antinuclear antibody, and a positive lupus band test on the skin. A renal biopsy showed lupus nephritis coexisting with podocytic infolding associated with TA, which has rarely been reported. After low-dose prednisolone therapy and immunosuppressive therapy by cyclosporine for 14 years, proteinuria has persisted without deterioration of serum creatinine levels.

Three children under the age of 3 years presented with malignant hypertension, proteinuria, and acute kidney injury. Takayasu's arteritis was diagnosed on the basis of clinical symptoms of weight loss and low grade fever in conjunction with elevated sedimentation rate and radiographic evidence of aortic and renal artery stenosis. One patient had a renal biopsy which showed arteriolar sclerosis and focal glomerulosclerosis. All three patients required multiple antihypertensive agents, ultimately including angiotensin receptor blockers and/or angiotensin converting enzyme inhibitors. The vasculitis was treated with pulse corticosteroids followed by cyclophosphamide in one patient and mycophenolate mofetil as maintenance therapy in all. Follow-up has ranged from 2 to 8 years. Although global renal function has normalized in each patient, two have unilateral non-function of one kidney. The last patient has persistent aortic and renal artery stenosis with complex collateralization requiring ongoing medical and anticipated surgical management.

Premature atherosclerosis has been observed during the course of different systemic inflammatory diseases such as rheumatoid arthritis and sytemic lupus erythematosus. Remarkably, relatively few studies have been published on the occurrence of accelerated atherosclerosis in patients with vasculitis. In giant cell arteritis (GCA), mortality because of ischaemic heart disease is not increased. In addition, intima media thickness (IMT) is lower in patients with GCA than in age-matched controls. In contrast, IMT is increased significantly in Takayasu arteritis, another form of large vessel vasculitis occurring in younger patients. In Takayasu arteritis and in Kawasaki disease, a form of medium-sized vessel vasculitis, accelerated atherosclerosis has been well documented. In small vessel vasculitis because of anti-neutrophil cytoplasmic autoantibodies-associated vasculitis, cardiovascular diseases are a major cause of mortality. IMT measurements reveal conflicting results. During active disease these patients experience acceleration of the atherosclerotic process. However, when inflammation is controlled, these patients have atherosclerotic development as in healthy subjects. Several risk factors, such as diabetes and hypertension, are present more often in patients with vasculitis compared with healthy controls. In addition, steroids may be pro-atherogenic. Most importantly, many patients have impaired renal function, persistent proteinuria and increased levels of C-reactive protein, well-known risk factors for acceleration of atherosclerosis. Enhanced oxidation processes, persistently activated T cells and reduced numbers of regulatory T cells are among the many pathophysiological factors that play a role during acceleration of atherogenesis. Finally, autoantibodies that may be relevant for acceleration of atherosclerosis are found frequently in elevated titres in patients with vasculitis. Because patients have an increased risk for cardiovascular events, vasculitis should be treated with as much care as possible. In addition, treatment should be considered with angiotensin-converting-enzyme inhibitors and/or angiotensin receptor-1 blockers, statins and acetylsalicyl acid. Finally, classical risk factors for cardiovascular disease should be monitored and treated as much as possible.

Takayasu arteritis is a large vessel systemic granulomatous vasculitis characterized by stenosis or obliteration of large and medium sized arteries. It commonly involves elastic arteries such as the aorta and its main branches. Renal artery involvement is rare and has not been reported in a child. We report a 12-year-old boy with Takayasu arteritis who developed severe hypertension, proteinuria, microscopic hematuria and renal dysfunction. Conventional angiography demonstrated aneurysms of both renal arteries and multiple microaneurysms of the superior mesenteric artery. This case report illustrates that the children with Takayasu arteritis can develop renal involvement resulting in hematuria, proteinuria and even renal failure.

Takayasu arteritis (TA) is a rare chronic large-vessel vasculitis of unknown etiology. Although commonly thought of as an adult disease, initial manifestations frequently appear during adolescence. This is a case discussion of an 11-year-old boy with a recent history of fever who presented with shortness of breath, sore throat, chest pain, hypertension, and a new murmur. He had a markedly elevated antistreptolysin O titer, had a prolonged PR interval, and was initially evaluated with acute rheumatic fever. After admission, he had persistent hypertension, proteinuria, and hemoptysis, which prompted a magnetic resonance angiography that revealed aortic enhancement and thickening, and he was evaluated with TA. To our knowledge, this is the first case report in the pediatric literature of TA presenting with heart block. This case highlights the recondite nature of the systemic vasculitides and emphasizes the importance of keeping a broad differential diagnosis when seeing patients who present with common complaints.

Patients with different forms of systemic vasculitis experience long-term morbidity and mortality caused by cardiovascular disease due to premature atherosclerosis. Epidemiologic reports of patients with GCA suggest that long-term mortality in this disease is not increased compared with the general population of the same age. The risk of a stroke, however, in particular in the vertebrobasilar territory, is increased. In addition, the occurrence of aortic aneurysmal disease and aortic dissection is also clearly increased in GCA. Mortality due to ischaemic heart disease, however, is not increased. In Takayasu arteritis accelerated atherosclerosis has been clearly documented both clinically and in autopsy reports. Atherosclerotic plaques in the carotid artery may be present in the carotid arteries especially in patients with a documented history of arteritis involving the carotid artery. It is controversial whether Kawasaki disease is associated with accelerated atherosclerosis. Young adults with a history of Kawasaki disease may have abnormal brachial artery reactivity, increased carotid IMT values and increased arterial stiffness. At autopsy examinations of KD patients, however, no significant atherosclerotic lesions are detected and carotid IMT measurements were found to be clearly different from those in young adults with familiar hypercholesterolaemia, suggesting that the remodeling process in KD is different from atherosclerosis. In ANCA-associated vasculitis (AAV), an increased mortality as a consequence of cardiovascular disease is well-documented. In these patients the relative risk for coronary heart disease is two- to fourfold that in control subjects. In addition, a similar relative risk has been found for stroke. Diabetes, hypertension, dyslipidemia, abdominal obesity (metabolic syndrome), impaired renal function, persistent proteinuria and increased production of C-reactive protein are common risk factors for premature atherosclerosis in patients with systemic vasculitis. Furthermore, cholesterol and its modifications play a pivotal role in the pathogenesis of accelerated atherosclerosis in vasculitis. The (preventive) therapy for accelerated atherosclerosis in systemic vasculitis is based on an aggressive approach against inflammation and against risk factors of premature atherosclerosis such as smoking, inactivity, obesity and unhealthy diet. In addition, patients should be treated with angiotensin-converting enzyme inhibitors and/or angiotensin receptor-1 blockers for hypertension and statins for dyslipidemia. Finally, low dose acetylsalicylic acid should be prescribed in patients with large vessel vasculitis, i.e., both in GCA and TA, who do not have contraindications for ASA.

Takayasu arteritis is a systemic vasulitis of large vessels that mainly involves the aorta and its branches. It normally presents in third decade of life and has rarely been reported in children under 10 years of age. We report here a case of Takayasu arteritis in a 5 years old girl who presented with headache, generalized body swelling, severe hypertension, proteinuria and minimal functioning kidneys. Conventional angiography demonstrated narrowing of descending aorta, right subclavian artery and right common iliac artery. She responded steroids, diuretics, antiplatelets and digoxin and discharged home on maintenance therapy.

We present a case report of pregnant woman with Takayasu's arteritis diagnosed in childhood. The treatment was modified owing to the fact that the patient wished to get pregnant and she conceived spontaneously within the first year after that. Vasculitis activity was low during pregnancy Hypertension was treated with methyldopa and metoprolol. After the confirmation of pregnancy daily administration of prednizone and enoxaparin (at a dose of 5 mg and 40 mg, respectively) has been started. In the third trimester of pregnancy the values of blood pressure increased. The patient required higher doses of antihypertensive drugs. Proteinuria appeared in the daily urine collection. The values of liver enzymes have increased. Elective cesarean section was performed at 37 weeks of gestation due to narrow oscillations revealed by CTG and weaker fetal movements reported by the mother A male infant (weight 2840 g, Apgar 10) was born. The mother and the child were discharged on day 5 of the postpartum. Treatment with steroids, antihypertensive drugs, thyroxine and enoxaparin was continued. Hypertension and preeclampsia are the most dangerous complications in pregnant women with Takayasu's disease. They can affect the health status of the mother and the child. Maternal blood pressure should be controlled very accurately on the two superior limbs. Vaginal delivery of the baby is preferred. Cesarean section is indicated when the values of the maternal blood pressure are elevated in the second part of vaginal delivery

Glomerulonephropathy is a rare complication of Takayasu's arteritis (TA). To date, most glomerulonephropathies associated with TA show the histological feature of mesangial proliferation. Membranous glomerulonephropathy (MG) is a form of glomerulonephropathy in which the mesangial proliferation is not conspicuous and its association with TA is extremely rare. A 54-year-old man was referred to our hospital due to progressive edema in the lower limbs and nephrotic range proteinuria. Five years previously, he underwent percutaneous angioplasty for left subclavian artery stenosis. Kidney biopsy revealed stage II MG. General examination including enhanced CT scan confirmed the presence of TA. He started oral prednisolone therapy at a dose of 40 mg daily. The C-reactive protein level normalized 7 days after the prednisolone therapy. Three months later, proteinuria had remitted. Though the true relationship between MG and TA was not revealed in present case, considering the fact that complete remission of nephrotic syndrome occurred following the improvement of C-reactive protein level in response to steroid therapy, TA might be the secondary cause of MG. To our best knowledge, only two case reports described the association of MG and TA previously. Those two patients, however, also demonstrated the feature of systemic lupus erythematosus in addition to TA. This is the first case report that describes a patient who presented as MG associated with TA, but not complicated by systemic lupus erythematosus.

Renal involvement in Takayasu's arteritis is frequent and worsens the progression of the disease. This is primarily a renal artery stenosis causing renovascular hypertension. The glomerular disease is exceptional. This study was undertaken to determine the clinical, radiological, biological features and therapeutic response in patients with kidney disease associated with Takayasu arteritis. A retrospective chart review was conducted on 11 patients (five men and six females), with a mean age of 31.1 years (19-40 years). The discovery of kidney disease preceded the diagnosis of Takayasu's arteritis in eight cases. Ten patients developed hypertension. Laboratory finding showed proteinuria in five cases of which one case was due to nephrotic syndrome. Renal failure was found in six cases including four cases in stage of terminal chronic renal failure. Impairment of the renal artery was present in nine patients, proximal in seven cases and distal in two cases, bilateral in five cases and unilateral in four cases. Narrowing renal artery was found in seven cases. The renal biopsy revealed membranoproliferative glomerulonephritis in one case and nephrosclerosis in another case. Eleven patients were followed for an average period of 155 months (3-335 months). Remission of nephrotic syndrome was concomitant with the remission of the disease. Seven patients developed outbreaks of Takayasu's arteritis of which six were in care. Relapse of nephrotic syndrome was concomitant with the outbreak of the disease followed by spontaneous remission of both diseases. Improved pressure was obtained in 5 cases and worsening renal function in seven cases. Death was observed in two cases.
