The renal uptake of radioactivity following intravenous administration of radiolabeled octapeptides is one of the highest among various organs making the kidney a potential target for radiation injury (771) quinine muscle relaxant mechanism cheap voveran sr 100 mg on line. No renal toxicity was observed in another trial that included 154 patients receiving cumulative doses up to 8. Many patients exhibit only mild renal insufficiency, and such patients may recover renal function with improvement in concurrent hematologic abnormalities (731). More severe cases may require dialysis; in such patients, mortality may be high (731). While antihypertensive properties of these drugs are definitely beneficial, the primary mechanisms of renoprotection appear to be vasodilation of the glomerular arterioles with consequent lowering of intraglomerular pressures and through potential antioxidant properties (763). Although no definite increase in markers of chronic oxidative stress was identified in the kidneys of a rat model after total-body irradiation (678), suppression of renin-angiotensin system has been proven to be clinically useful in randomized controlled studies to limit the radiation nephrotoxicity in hematopoietic transplantation (699,761). Individual studies suggest that administration of anticoagulant sulodexide (669) and the anti-inflammatory agent dexamethasone (765) also may diminish the nephrotoxic effect of radiation in experimental systems, but such findings have not yet been translated into clinical trials in human patients. The low molecular weight proteins such as octreotide are filtered through the glomerular capillary basement membranes followed by tubular reabsorption. Multiple transport mechanisms appear to be involved in the proximal tubular reabsorption of these peptides (767). But in vitro studies suggest that the primary reabsorption mechanism is by receptor-mediated endocytosis, possibly involving megalin and cubilin receptors in proximal tubules (783). These peptides may also be actively secreted from the peritubular capillary blood into the tubular lumen (767). Proteolytic digestion of the peptides by tubular lysosomal enzymes results in breakdown products including radionuclide-chelated amino acids. Entrapment of these chelated amino acids within the kidney tubules occurs by binding to intracellular metal-binding proteins. Several studies indicate that development of radiation nephropathy after radionuclide therapy likely depends on multiple factors, such as dose of radiation, the type of isotope, the characteristics of the carrier monoclonal antibody or peptide used, such as size, charge, and clearance pathways, individual renal volume, dose rate, and fractionation. The severity of nephrotoxicity can be reduced by accurate pretreatment renal dosimetry, especially in the setting of renal impairment (784). Alpha emitters, such as 111In, have high ionizing properties over a short range that result in a high relative biologic effectiveness as compared to a similar dose of x-rays (785). The mean particle range of Auger electrons emitted by 111In is less than one cell diameter, while beta particles emitted by 90Y have much deeper penetration range (R95 5. The nephrotoxicity can be reduced by several methods that limit tubular reabsorption of and damage by these radiolabeled peptides. The pharmacokinetics of the peptides can also be altered by adding polyethylene glycol groups or albumin-binding sequences, with resultant renoprotection (789). The competition for the negative charges on the tubular basement membrane between the radiolabeled compound and other cationic compounds may also inhibit renal tubular reabsorption (790,791), and radiolabeled monoclonal antibodies could be inhibited significantly by cationic amino acids (792). There are several human studies indicating that renoprotection during radionuclide therapy can be achieved by coinfusions of cationic, basic amino acids such as lysine and arginine (776,794,795). Eleven of sixty-five patients in this study had more than 15% decline of creatinine clearance per year. Although experimental, other protective modalities of proximal tubular reabsorption interference include disruption of endocytosis by reducing the energy supply using maleate that inhibits the citric acid cycle and blocking tubular transporters by using probenecid (797). The oxidative stress caused by radionuclide-induced release of free radicals can be countered by using radioprotectors such as amifostine (798). Dose fractionation may give the normal tissue a chance to repair between the irradiation cycles without significantly altering the tumor response (798). Although somatostatin analogs are most commonly used, many other radiolabeled peptides have been studied including gastrin, cholecystokinin, and exendin analogs that target gastrin receptor, cholecystin-2 receptor, and glucagon-like peptide receptors, respectively, expressed by various neuroendocrine and nonneuroendocrine tumors (799,800). The toxicity depends on multiple factors, including the dose of radiation, type of radionuclide, and the physicochemical properties of the carrier molecules. Renal toxicity can be limited by various renoprotective modalities during therapy; however, gradual renal functional deterioration over long range may still be the consequence.

Segmental deposits of insudative/degenerative material in diabetes and focal segmental glomerulosclerosis often react with antibodies to IgM and C3 used in the routine panel of immunofluorescence stains quinine muscle relaxant mechanism generic 100 mg voveran sr otc. Diabetic fibrillosis is typically associated with the typical light microscopic and immunofluorescence microscopy findings of diabetic nephropathy. The clinical information available should also be correlated with the overall biopsy findings. Ultrastructural immunolabeling may also be helpful to link specific antigenic epitopes to ultrastructural correlates, thus clarifying their nature (110). Immunoelectron microscopy demonstrates a frequent association of complement component with these structuures, especially C3d and C9 (113). All these can be confusing to the inexperienced eyes and even troublesome to experienced renal pathologists. The fibrillary material in the mesangium is predominantly 4 to 6 nm in diameter and difficult to discern in the normal mesangium. When the fibrils that normally form the mesangium become prominent, as in the case in mesangiolysis, the fibrillary nature of the mesangial matrix becomes noticeable and may be confused with other fibrils such as amyloid. While matrix fibrils most commonly appear organized and display a parallel arrangement, amyloid fibrils are randomly disposed. In a variety of other conditions, the mesangial matrix may acquire a fibrillary substructure. This may represent biochemically abnormal, structurally deformed, normally or aberrantly synthesized matrix. For example, as noted earlier in this chapter, in a subset of patients with nodular diabetic glomerulosclerosis, the increased extracellular matrix has a conspicuous fibrillary texture (diabetic fibrillosis) (36,61,62). Fibrillary Glomerular sclerosis may be associated with the deposition of banded fibrillary collagen and/or nonfibrillary collagen, as well as precollagen. In this setting, precollagen can also be a source of confusion, as it lacks the typical banding pattern of mature collagen. Segmental glomerular sclerosis represents more of a problem than global glomerular sclerosis. It is difficult to identify specific diagnostic features in globally sclerosed/hyalinized glomeruli and in segmentally sclerosed glomeruli where areas with hyalinosis and cellular debris are common findings. Cellular Debris Cellular debris in the mesangium may have a variety of ultrastructural appearances difficult to separate from diagnostically specific structures. This debris may be associated with complement components detectable by immunoelectron microscopy (113). This may be a source of confusion with diagnostic entities such as immunotactoid glomerulopathy (114). Intracellular Fibrils Intracytoplasmic fibrils may sometimes appear to be extracellular and create confusion if the cellular outlines become ill defined as a consequence of pathology. This occurs in particular in cases where the cell membranes are not well preserved and it becomes difficult to separate intracellular from extracellular compartments (9). Fibrin Tactoids On light microscopy, this material generally appears vaguely fibrillary. Phosphotungstic acid-hematoxylin stain may be useful to confirm the presence of fibrin, which stains blue. It is in these situations that confusion with fibrillary material such as amyloid may occur. Artifacts are most prevalent in specimens mishandled as a result of delay or improper fixation of the samples or retrieval from paraffin or frozen blocks. Prompt and adequate fixation of the renal biopsy samples eliminates the majority and most common artifacts. Use of the proper fixative for ultrastructural evaluation and sectioning of the samples into small 1-mm cubes allows for adequate penetration of the fixative, and appropriate fixation generally avoids artifacts. Overheating of tissues while processed for light microscopy results in marked tissue changes, especially if specimens are taken from paraffin blocks and reprocessed for electron microscopy. B: Microspherical particles in subepithelial deposits of membranous glomerulonephritis. These should not be confused with microspherical particles that are not artifacts but rather are a distinctive feature of a disease process. These microspherical particles are not artifacts and typically are present in repeat biopsies from the same patient. The epidemiology and clinical course of these patients are similar to other matched membranous nephropathy cases. Similar particles have also been reported in focal, segmental glomerulosclerosis (115). Delineation between intra- and extracellular compartments may become blurred, as cellular membranes may disappear or fragment when samples are not handled appropriately. Extracellular matrix artifacts can mimic structured deposits such as cryoglobulins or deposits seen in immunotactoid glomerulopathy (116), among others. Fibrillary glomerulonephritis: an entity with unusual immunofluorescence features. Renal diseases with organized deposits: an algorithmic approach to classification and clinicopathologic diagnosis.

Alternatively muscle relaxant sciatica purchase voveran sr 100 mg line, gain-of-function CaR mutations lead to hypocalcemia and hypercalciuria owing to hypoparathyroidism (349,378). These mutations cause autosomal dominant as well as sporadic cases of hypoparathyroidism (381). In individuals with gain-of-function mutations, the hypercalciuria leads to an increased tendency toward developing nephrocalcinosis and nephrolithiasis (378,382). Other symptoms vary by patient; some have asymptomatic hypocalcemia, whereas others may have spasms and seizures due to hypocalcemia (378). Vitamin A taken as a dietary supplement can build up in tissues and produce acute as well as chronic toxicity. Hypercalcemia caused by vitamin D excess has been documented to occur in several ways. Cases of ingestion of excessively fortified milk have been reported (386,387), with some individuals developing hypercalcemia. Whether the lymphomatous cells themselves produce the excess vitamin D or whether, as suggested by Hewison et al. Pathologic descriptions of vitamin D excess in the older literature depict kidneys that are normal in size or enlarged, pale, swollen, and yellow. Calcification takes place in all segments of the tubules, and foreign body giant cells are sometimes seen. Tubular loss, lymphocytic infiltration of the interstitium, periglomerular fibrosis, and sclerosis may all be present (389). Metastatic calcification may be evident in the heart, arteries, this syndrome was formerly a complication of peptic ulcer disease in patients who took large quantities of milk and absorbable alkali as therapy, which led to hypercalcemia and alkalosis. With the advent of histamine blockers, the classic milk-alkali syndrome became rare; however, cases of milk-alkali syndrome associated with the use of calcium carbonate to treat osteoporosis or chronic renal failure became more common. Renal pathologic descriptions are scanty, but they document foci of calcification in the tubules and interstitium with interstitial fibrosis and inflammation (393). Defects of Tubular Handling Vitamin A or D Excess Although not always associated with hypercalcemia, several disorders of tubular handling are associated with nephrocalcinosis and/or nephrolithiasis owing to hypercalciuria. Abnormalities have been identified in paracellin, a tight junction protein, in phosphate transporter regulatory proteins, and in potassium channels and chloride channels. Familial hypomagnesemic hypercalciuria, autosomal dominant hypoparathyroidism, antenatal Bartter syndrome (or hyperprostaglandin E syndrome), and classic Bartter syndrome all have in common hypercalciuria, which predisposes to nephrocalcinosis and nephrolithiasis. Pathology of Renal Calcification (Nephrocalcinosis) Renal calcification refers to calcium deposits in the form of calcium phosphate and calcium oxalate in the kidney parenchyma. In most cases, calcium phosphate deposits are focal and may be seen in many conditions including in patients with significant proteinuria, following ischemic tubular injury, aging kidneys, and preterm babies partly because of intrinsic kidney calcium losses and partly from enhanced calcium excretion following diuretic therapy (399). Diffuse calcium phosphate crystals are particularly associated with oral sodium phosphate bowel preparations (phosphate nephropathy) and gastric bypass surgery (dumping syndrome). Calcium phosphate deposits appear purple on H + E (basophilic) and stain black with von Kossa stain and red with alizarin red, which stains calcium (red). Calcium phosphate crystals do not show birefringence under polarized light in contrast to calcium oxalate. Calciumcontaining deposits were called dystrophic in the older pathology literature and the term nephrocalcinosis referred to deposits associated with tissue necrosis or malignancy. Recent autopsy studies found kidney calcium deposits in 223 out of 12,960 autopsies; an incidence of 1. Calcium-containing deposits can be classified according to location as cortical or medullary. Medullary sponge kidney (a distinctly radiologic diagnosis recognized by calcifications in the collecting ducts) is an example of exclusive medullary calcium deposits (see Chapter 4). Some authors use the term crystalline nephropathies for calcium-containing kidney deposits and include four categories: (a) calcium-containing deposits, (b) drug-induced crystals, (c) metabolic- or genetic-associated deposits, and (d) dysproteinemia (400). In the early stages, the structures are pale to clear with rounded or somewhat irregular contours. As they grow, they progressively calcify and become granular and basophilic, sometimes with a faintly lamellar appearance resembling miniature psammoma bodies. The tubular cytoplasm, if it persists, becomes flattened and pale, but often, it is completely eroded away. These isolated concretions are usually confined to the tubule without surrounding inflammation. Phosphate crystals in hyperthyroidism are deposited along the basement membrane of the proximal tubules. Calcium Phosphate Crystals and BowelCleansing Agents (Phosphate Nephropathy) Diffuse calcium phosphate crystals are particularly associated with oral sodium phosphate bowel preparations, also called phosphate nephropathy. Deposition of nonpolarizable calcium phosphate crystals in this case are found without hypercalcemia or other known risk factor for the development of nephrocalcinosis. Most of these patients have normal renal function prior to the procedure and develop acute renal failure following colonoscopy. Calcium phosphate crystals in phosphate nephropathy have a brown color and stain black with von Kossa stain. Calcium Oxalate (CaOx) Nephropathy these deposits are often found in end-stage native kidneys and allograft kidneys (36,402). In many instances, nephrocalcinosis is but one manifestation of multiorgan calcification in the liver, spleen, adrenals, and lymph nodes during the course of disseminated infection with Pneumocystis carinii organisms (403). Acute and chronic tubular injury and inflammation occur in early stages of CaOx deposition, sometimes including a giant cell reaction; later, there is tubular atrophy and interstitial fibrosis. Dietary, metabolic, and endocrine factors including obesity, diabetes, hypertension, cardiovascular disease, atherosclerosis, dyslipidemia, and other diseases predispose stone formation. The majority of patients with nephrocalcinosis are men; most stones in women are due to either metabolic defects such as cystinuria or infection. The peak age at first episode is approximately 30 to 40 years with a later initial presentation Adrenal Disorders Nephrocalcinosis and nephrolithiasis have been described in primary hyperaldosteronism due to adenoma producing excess aldosterone leading to significant hypertension and nephrocalcinosis, persisting despite removal of the tumor (406).

Voveran sr 100 mg buy with mastercard

As noted earlier spasms headache discount voveran sr 100 mg with amex, interstitial changes may be found in relation to tubular changes (137). In older patients, preexisting vascular abnormalities, such as arterial and arteriolar sclerosis, may be seen, and, according to Gallo et al. Arteritis has been described (140), but in such cases, systemic necrotizing vasculitis must be excluded. The pattern is granular ("lumpy-bumpy") and usually more coarse than in patients with membranous glomerulonephritis. These deposits may assume a somewhat linear or band-like (garland) pattern in some areas, owing to the confluence of subepithelial deposits. The granular deposits correspond to the glomerular subepithelial deposits evident on electron microscopy, although there has been controversy over this feature in the past (153). The garland pattern has a discrete, more densely packed and sometimes confluent heavy disposition of IgG and C3, corresponding to numerous humps noted on the subepithelial side of the glomerular capillary wall (147,149). This picture may turn into the mesangial pattern, characterized by a granular deposition of IgG and C3 (usually with predominance of C3). In B, there are hypercellularity and numerous subepithelial deposits of varying density. The deposits are generally noted in the mesangial matrix of the glomerulus and are accompanied by mesangial hypercellularity. Edelstein and Bates (154) studied 42 adult patients with characteristic acute postinfectious glomerulonephritis and divided the biopsies into these three subtypes. Patients with the garland pattern had significantly more proteinuria, whereas the renal biopsies with the mesangial pattern had a lesser degree of glomerular hypercellularity and leukocytes. There are diffuse and irregularly distributed fine and coarse granular deposits in the glomerular capillary walls and in the glomerular mesangial regions. The lumen of the glomerular capillary is totally occupied by a monocyte and by endothelial cells with prominent nuclei and swollen cell bodies. Granular deposits are found in the mesangial regions, although the glomerular capillary wall remains largely negative. A portion of the glomerulus shows marked proliferation of mesangial cells but free and open glomerular capillary lumens. Mesangial deposits are located in the mesangial matrix, and individual subepithelial deposits are present in the region of the mesangial waist (arrow). B: Accompanying electron micrograph from the same patient showing mesangial electron-dense immune-type deposits. The patient was a 51-year-old diabetic male with low C3, normal C4, very high antistreptolysin-O titer after a sore throat. The biopsy showed diffuse endocapillary proliferative glomerulonephritis with polymorphonuclear leukocytes in the glomeruli as well as in the interstitium. B the starry sky pattern was noted in four of five patients with a crescentic pattern and six of seven patients with a chronic course (154). There is no evidence so far that different etiologic factors are responsible for these three subtypes (148). The individual immune response of the host and the stage of the disease are likely to play a role in their genesis. A diffuse granular pattern for IgG and, usually, C3 is also found in patients with subclinical glomerulonephritis (146,150,151) and in those with minimal urinary changes. There is usually more intense and more constant staining with anti-C3 than with anti-IgG (145,146,150,151). Some authors have noted the combination of granular and patchy, interrupted linear staining along the glomerular capillary wall and in the mesangial regions (59,88). This interrupted linear pattern has been found most commonly either in patients in whom the initial renal biopsy was performed at a later stage than usual or in subsequent biopsies (59). C3 without the presence of IgG has been recorded in the mesangial areas with no capillary wall deposits (149). This pattern also tends to be seen in patients who undergo biopsy later than usual. They suggested that IgG may have been covered up by C3, thus preventing its detection. Another explanation could be that C3 reaches detectable levels for the immunofluorescence technique, while IgG remains below the threshold level of detection. It was thought that the interrupted linear deposits of C3 in the absence of IgG could be the result of a direct toxic effect of the organism. In C3 glomerulonephritis, the glomerular deposits do not truly represent immunoglobulin-containing immune complexes. IgM is frequently present and was recorded in more than 50% of cases in one series (131). IgA is usually absent (59,145,146), but it has been noted from time to time (131,150,151). If IgA immunofluorescence is strong in postinfectious glomerulonephritis, the possibility of an underlying staphylococcal infection has to be considered irrespective of presence or absence of diabetes mellitus (section on Glomerulonephritis associated with staphylococcal infections). IgE has seldom been sought; in one series of 10 patients, it was present in 5 biopsies (151). Fibrin/ fibrinogen-related antigen also can be detected in the mesangial regions (as well as in the Bowman space in the crescentic form) (59,131,146). In three of these patients, the pattern was granular along the glomerular capillary walls, whereas in five, it was noted in the mesangium together with C3. Classic pathway components of complement, such as C1q and C4, are generally lacking (146,150,151). These various observations support the role of the alternative pathway of complement activation in postinfectious glomerulonephritis (151).

The absence of casts in multiple sections taken from autopsy kidneys represents substantial evidence that this lesion is clearly separable from light chain cast nephropathy and that it represents a specific pattern of renal damage in patients with plasma cell dyscrasias (164). Because the diagnosis requires the demonstration of monotypic light chains along the tubular basement membranes, it cannot be established by light microscopy alone. Highly concentrated monotypic light chains are also noted in proteinaceous material in tubular lumina, which does not organize into well-formed casts (150). Etiology and Pathogenesis Immunofluorescence Linear monotypic light chain staining may be demonstrated outlining the tubular basement membranes in association with the most intense interstitial inflammation. There may also be intracytoplasmic staining in proximal tubular cells for the monotypic light chain (147,164). As with acute tubulopathy, there are cases in which staining for both light chains is present, but if the pertinent light chain is more prominently stained, this finding supports the diagnosis. The inflammatory interstitial reaction that may occur in these cases is probably induced by the binding of pathogenic light chains to the tubular basement membranes, which alters intrinsic tissue antigens and promotes the release of cytokines, resulting in chemoattraction and activation of interstitial mononuclear inflammatory components (166,167). Light chains may reach the tubular basement membranes by transcytosis after reabsorption or by passive tissue diffusion from peritubular capillaries (164). Immunohistochemistry Differential Diagnosis In some of these cases, monotypic light chain staining deposition along tubular basement membranes in areas with interstitial inflammation and tubulitis can be clearly demonstrated using immunohistochemistry (164). Specifically, neither there are light chain deposits nor there is evidence of amyloid deposition. In some cases, there may be focal deposition of light chains, represented by punctate to powdery, electron-dense material along the outer aspect of the tubular basement membranes (147,147a,164). By ultrastructural immunogold technique, distinct labeling for monotypic light chains can be demonstrated along the tubular basement membranes in areas with prominent interstitial inflammation and in tubules exhibiting tubulitis. When eosinophils are present, a hypersensitivity reaction is an important consideration in the differential diagnosis. It is imperative for an accurate diagnosis to demonstrate that monotypic light chains are associated with the tubulointerstitial compartment using ancillary diagnostic techniques. Interestingly, proximal tubulopathy with basolateral monoclonal light chain deposition can also be associated with an interstitial inflammatory response (147,147a). Treatment, Course of the Disease Process, and Prognosis this disease may require steroid therapy, just as needed for any type of tubulointerstitial nephritis (97) and treatment of the plasma cell clone producing the tubulopathic light chains. Note labeling of tubular basement membranes for (A) but not (B) light chains in an area with prominent interstitial inflammatory activity. There are no specific studies addressing kidney survival or the clinical course of this disease. Historical Perspective In 1957, Kobernick and Whiteside showed nonamyloid glomerular abnormalities in patients with myeloma and recognized the similarity of these lesions with diabetic nephropathy (173). Rapid deterioration of renal function occurs as the disease advances, if not treated aggressively. Careful evaluation of the plasma cells in the latter case using either immunohistochemical techniques or flow cytometry can identify a monoclonal population of plasma cells, albeit a small clone in many cases. Biosynthetic studies of the plasma cells often demonstrate paraprotein production, even when serum and urine electrophoresis fail to show any abnormalities (40). Even with use of the most sensitive techniques available, the percentage of patients falling into this category remained at 15% to 20% (186). Light Chain Deposition Disease Clinical Presentation and Laboratory Findings Gross Pathology There is no significant sex predilection for this disease, but males predominate slightly in most series (7:5). At the time of diagnosis, acute renal failure is present in 30%, and a similar percentage is dialysis dependent. Interestingly, full-blown nephrotic syndrome is noted in a minority of these cases (156). These cases comprised approximately 10% of all cases with myeloma that died during the period of time this study covered at the institution. The mesangial nodules are argyrophilic and composed of extracellular matrix proteins admixed with monotypic light chains (196,197), and the principal matrix protein deposited is tenascin (197). In silver methenamine-stained sections, there may be lamellation of the peripheral portions of the mesangial nodules. Mesangial hypercellularity accompanies the increase in extracellular matrix in some of the cases. The peripheral capillary walls are variably thickened, and the capillary wall alterations are uneven from one glomerulus to the other and as well as within the same glomerulus. The thickened walls are a consequence of the subendothelial deposition of light chains (110,156).

C: Higher magnification of the arteritis demarcated by the box showing transmural inflammation that has completely destroyed the muscularis on the right knee spasms causes best voveran sr 100 mg. The muscularis on the left is partially destroyed and has focal edema and slight focal accumulation of fibrinoid material. The infiltrate contains predominantly mononuclear leukocytes that are primarily monocytes and macrophages. Even though immunohistology demonstrated increased macrophages in glomeruli, no glomerular hypercellularity could be discerned by light microscopy in routinely stained sections. Theoretically, the glomerular macrophages may have broken away from the inflamed surface of larger arteries and embolized to the glomerular capillaries. Focal intestinal mononuclear cell infiltrates with prominent IgA-positive plasma cells have been described in kidneys of patients undergoing autopsy; however, IgA-positive plasma cells are more conspicuous in the coronary arteries and respiratory tract (77). As with other forms of arteritis, acute inflammatory lesions evolve into sclerotic lesions that often are accompanied by intimal thickening and gaps in the elastic laminae (68). B: Higher magnification of the arteritis demarcated by the box showing a histologically unremarkable segment of an interlobar artery on the right, leading into a severely inflamed segment of artery on the left. C: Higher magnification of the arteritis demarcated by the box showing transmural inflammation that extends from the markedly thickened intima (left), through the edematous and necrotic muscularis, to the inflamed perivascular adventitia (lower right). C raises the possibility of an etiologic role for an infectious pathogen or environmental antigen or toxin, but no such agent has been identified. These animal models raise the possibility that the human disease is the result of a genetic predisposition to develop a pathogenic innate or acquired immune response to a pathogenic organism. The predominance of monocytes rather than T cells in the early lesions favors an innate rather than an acquired immune response. C predilection for the coronary arteries although many other arteries may be involved, and (c) a pattern of inflammation in arteries that shares features with other forms of necrotizing arteritis but has distinctive characteristics of its own. If not treated early in the course of the disease, approximately 15% to 25% of patients will have serious cardiovascular damage such as myocardial infarction or sudden death (64). The disease also has been called aortic arch syndrome and pulseless disease because it often affects the aortic arch and the arteries arising from it and frequently causes diminished or absent pulses, especially in the upper extremities, because of arterial narrowing. Takayasu arteritis has a strong female predilection, with a female-to-male ratio of approximately 9:1. Affected individuals are usually between 10 and 20 years old, and it rarely occurs after 50 years of age. The differences in age distribution, demographic characteristics, and vascular distribution warrant considering these to be different forms of vasculitis. In addition to nonspecific constitutional symptoms such as fever, arthralgias, and weight loss, the major clinical manifestations of Takayasu arteritis are reduced pulses, vascular bruits, claudication, and renovascular hypertension (46,88,90,91,93,94). In an American College of Rheumatology study of 63 patients (46), 98% had reduced pulses, 98% had claudication, and 90% had subclavian or abdominal bruits. The major cause is renal ischemia secondary to renal artery stenosis, aortic coarctation, or both, although reduced aortic elasticity and impairment of carotid artery baroreceptors may play a role in some patients (10). Adequate control of renovascular hypertension may not be possible medically, and these patients may require surgical vascular repair (10,97) or transluminal angioplasty (98). In some instances, the lumen may be completely obliterated, usually by firm pale fibrous material rather than acute thrombus. The inflammatory infiltrates contain predominantly lymphocytes and macrophages with varying numbers of multinucleated giant cells. In some specimens, apparently in earlier phases of the disease, the inflammation is more pronounced in the media and adventitia. In the aorta, there is patchy destruction of medial elastic lamellae by the inflammation. In the chronic phase of the disease, the inflammation is replaced by fibrous scars with only a few scattered chronic inflammatory cells. The sclerotic changes, including marked intimal thickening, often result in luminal narrowing, which can be made worse acutely by thrombosis. Exacerbation of active granulomatous inflammation may be superimposed on sclerotic lesions (94). The kidney parenchyma may show histologic evidence for chronic hypertensive nephrosclerosis or, rarely, malignant hypertensive nephropathy (94,95). Pathologic Findings Gross Pathology Gross aortic lesions include segmental stenosis (80% of patients), dilation without overt aneurysm (60%), aneurysm (20%), and dissection (10%) (94). There is slight focal fragmentation and fraying of the internal elastic lamina; however, important in the differentiation from primary hypertensive arteriosclerosis, there is no replication of silver-positive laminae within the thickened intima. The diverse patterns of glomerular disease observed at least raise the possibility that they are coincidental or idiosyncratic occurrences. The most commonly described lesion is mesangial hypercellularity (103) and the most distinctive lesion that has been reported is nodular mesangial matrix expansion and mesangiolysis (99). No definitive data are available on the evaluation of the arteritis of Takayasu arteritis by immunohistology or electron microscopy. The internal elastica is running vertically near the center of the image with a markedly thickened intima on the right and the lumen at the far right.

It represents infiltration of fibrin across the endothelial barrier, incorporation of an intraluminal thrombus into the vessel wall, or coagulation within the vessel wall. In addition, red blood cells or fragments of red blood cells (schistocytes) may be seen in the vascular lumina and permeating the vessel wall. Mucoid intimal hyperplasia of the interlobular arteries with prominent luminal narrowing. A: A small interlobular artery shows luminal narrowing due to pale mucoid intimal thickening and myointimal cellular proliferation. The internal elastic lamina is usually intact, but it may be slightly frayed with no major breaks or gaps. The media and the adventitia of the affected arteries are usually unremarkable; however, the media may be thinned by stretching around the extended intima, and the adventitia has been noted by some authors as being slightly fibrotic (439). Fibrinoid necrosis of the afferent arterioles consists of fibrin in the arterial walls, as seen with small arteries, but the extent of the change is much greater, and the entire wall may be involved. The arteriolar wall may have a smudgy appearance because of swelling of endothelial cells and medial myocytes. Inflammatory cells are usually not seen in fibrinoid necrosis, but such cells may occasionally be present. Sometimes, the arteriolar fibrinoid necrosis is accompanied by luminal thrombus, and on occasion, the process continues into the hilar region of the glomerulus. Arteriolar thrombi were detected in greater frequency than glomerular thrombi in patients with scleroderma renal crisis (549). Diffuse or focal C4d positivity in the renal arteries and arterioles has also been shown in patients with scleroderma renal crisis (549). Tubules are necrotic in the infarcted areas, and sometimes enclaves of necrotic tubules may be found without necrosis of the nearby glomeruli. Extensive (circumferential) fibrin insudation (fibrinoid necrosis) is seen in a small interlobular-size artery. Detachment of the endothelium from the underlying basement membrane is accompanied by subendothelial fibrin deposition in a small interlobularsize artery. There is significant chronicity with extensive tubulointerstitial fibrosis, ischemic glomeruli, and intimal fibroplasia of an interlobular size artery. The patient presented with scleroderma renal crisis; however, she had a long-standing history of systemic sclerosis. This finding does not imply infection but simply represents the normal cellular reaction at the periphery of an infarct; because the infarcts are small, the neutrophilic infiltration appears extensive. The extent of the positivity correlated with worse clinical outcome and also with peritubular capillary leukocyte margination and mild interstitial inflammation. Immunofluorescence Microscopy Fibrin or fibrinogen can be observed along the glomerular capillary walls and sometimes in the mesangium. Glomerular immunostaining with IgM and with C3 is more frequently seen than staining with IgG, IgA, C1q, and C4. Complement factors C3 and C1q are found with the same frequency as IgM, and C4 also has been commonly reported. In one case, scattered hyaline deposits with a periodicity of 9 to 12 nm were found in a subendothelial position in the glomerular capillaries. Glomerular intracapillary thrombi, if present, are composed of fibrin and platelets frequently admixed with fragmented red blood cells. Granular deposits were found in a subendothelial position in the arterioles and were indistinguishable from those seen in patients with hypertension. Fibrin tactoids and fragmented red blood cells can occasionally be seen embedded in the ground substance. Elongated myointimal or smooth muscle cells are present, but no discrete "immunetype" electron-dense deposits corresponding to the positive immunofluorescence findings have been noted. However, differentiation of "immune-type" deposits from areas of hyaline insudation may be difficult. The broad electron-lucent widening between the endothelium and the lamina densa. This widening of the lamina rara interna corresponds to the thickened glomerular capillary walls seen by light microscopy. Thickening and occasional "reduplication" of the glomerular the kidneys of these patients lack distinctive pathologic features and, when seen at autopsy, reveal fibrous intimal arterial thickening with areas of interstitial fibrosis or tubular atrophy. Photomicrograph shows strong fibrinogen positivity in an interlobular size artery (A). IgM positivity is present in the arteriolar wall and also along some of the glomerular capillary walls (B). However, the most severe intimal thickening was observed in patients with scleroderma renal crisis. Of the 44 hypertensive patients, 11 presented with the abrupt onset of severe hypertension associated with rapid deterioration of renal function; they had a poor prognosis-9 died within 2 months and the other 2 underwent bilateral nephrectomy and long-term dialysis. The remaining 33 patients had mild to moderate hypertension, and only 5 died during the follow-up period, the mean of which was 4. There was a longer interval between clinical onset of scleroderma and the development of hypertension in these 33 patients. Presumably, the pathologic features of this group would correspond to what was described in the previous section as the "chronic form," but knowledge of the natural history and pathology of this disorder is limited.
