Abstract
Renal disease associated with pulmonary hemorrhage is seen in a variety of clinical disorders and is a common cause of admission to intensive care units. Recent advances in the understanding of the pathogenesis of these disorders have improved the therapeutic options significantly and have favorably influenced the course of many of these disorders. This article discusses rheumatologic diseases that involve both the kidney and lungs, with emphasis on pathogenesis and therapeutic options. Common pulmonary-renal syndromes including anti-glomerular basement membrane disease and anti-neutrophil cytoplasmic autoantibodies-associated vasculitis.

Abstract
Antineutrophil cytoplasmic antibodies (ANCA) are useful serologic markers for the diagnosis and management of patients with Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA). However, problems in diagnosis and classification may occur when patients with other disorders develop ANCA. A 7-year review (1993-1999) disclosed 247 patients whose sera tested positively for ANCA by an indirect immunofluorescence method: 166 patients for cytoplasmic-ANCA (C-ANCA) and 81 patients for perinuclear-ANCA (P-ANCA) Twenty-seven patients had active pulmonary disease and underwent open-lung biopsy or transbronchial biopsy. Eight patients (30%) had a disease other than WG or MPA, and their clinical, pathological, and serological findings were reviewed. The patients, all women, ranged in age from 28 to 77 years (median, 37 y). Dyspnea (n = 6), cough (n = 6), chest pain (n = 2), and/or hemoptysis (n = 2) were present. The duration of symptoms lasted from 3 weeks to 6 years (median, 6 mo). ANCA titers were C-ANCA (n = 4; range, 1:40-1280) or P-ANCA (n = 4; range, 1:40-640). The lung biopsies disclosed nonspecific interstitial pneumonia (n = 4), bronchiolitis obliterans organizing pneumonia (n = 1), diffuse alveolar damage (n = 1), organizing diffuse alveolar hemorrhage without capillaritis (n = 1), and necrotic granuloma (n = 1). No cases showed characteristic histology for WG or MPA. The final diagnoses were various connective tissue disorders (n = 5), chronic hypersensitivity pneumonia (n = 1), postinfectious bronchitis/bronchiectasis (n = 1), and ulcerative colitis-related lung disease (n = 1). Surgical pathologists should be aware that significantly elevated ANCA titers may be associated with diverse forms of pulmonary disease. ANCA positivity alone, in the absence of appropriate clinical or pathologic findings, should not be used to substantiate a diagnosis of WG or MPA.

Abstract
A case is described involving Sjögren's syndrome, high sustained levels of antibodies to serine proteinase 3, and cavitating lung disease. Possible diagnoses accounting for this unusual combination include a novel association of Sjögren's syndrome and Wegener's granulomatosis (suggested by the high and sustained levels of antibodies to serine proteinase 3) or a rare presentation of bronchiolitis obliterans organising pneumonia. Identification of the true nature of the patients illness facilitated more active management and a swift resolution of the clinical problem.

Abstract
CONTEXT The term pulmonary-renal syndrome has been used frequently to describe the clinical manifestations of a great number of diseases in which pulmonary hemorrhage and glomerulonephritis coexist. The classic example of this type of vasculitis is Goodpasturés syndrome, a term used to describe the association of pulmonary hemorrhage, glomerulonephritis and the presence of circulating antiglomerular basement membrane antibodies (anti-GBM). Among the several types of systemic vasculitides that can present clinical manifestations of the pulmonary-renal syndrome, we focus the discussion on two types more frequently associated with antineutrophil cytoplasm antibodies (ANCA), microscopic polyangiitis and Wegener's granulomatosis, concerning a 10 year old girl with clinical signs and symptoms of pulmonary-renal syndrome, with positive ANCA and rapidly progressive evolution. CASE REPORT We describe the case of a 10-year-old girl referred to our hospital for evaluation of profound anemia detected in a primary health center. Five days before entry she had experienced malaise, pallor and began to cough up blood-tinged sputum that was at first attributed to dental bleeding. She was admitted to the infirmary with hemoglobin = 4 mg/dL, hematocrit = 14 %, platelets = 260,000, white blood cells = 8300, 74 % segmented, 4 % eosinophils, 19 % lymphocytes and 3 % monocytes. Radiographs of the chest revealed bilateral diffuse interstitial alveolar infiltrates. There was progressive worsening of cough and respiratory distress during the admission day, when she began to cough up large quantities of blood and hematuria was noted. There was rapid and progressive loss of renal function and massive lung hemorrhage. The antineutrophil cytoplasm antibody (ANCA) test with antigen specificity for myeloperoxidase (anti-MPO) was positive and the circulating anti-GBM showed an indeterminate result.

Abstract
There have been a number of recent advances in this field. First, the "International Consensus Statement on Testing and Reporting of Antineutrophil Cytoplasmic Antibodies (ANCA)" has been developed to optimize ANCA testing. It requires that all sera are tested by indirect immunofluorescent (IIF) examination of normal peripheral blood neutrophils and, where there is positive fluorescence, in enzyme-linked immunosorbent assays (ELISAs) for antibodies against both proteinase 3 (PR3) and myeloperoxidase (MPO). Testing will be further improved when international standards and common ELISA units are available. Second, new diagnostic criteria for the small vessel vasculitides that take into account ANCA-positivity and target antigen specificity as well as histologic features are currently being produced. Third, we understand that the complications associated with treatment of the ANCA-associated vasculitides are often more hazardous than the underlying disease, and regimens that use effective but less toxic agents are being evaluated. The factors associated with increased risk of relapse, however, remain incompletely understood. Finally, ANCA with specificities other than PR3 and MPO are present in many nonvasculitic autoimmune diseases. Their clinical significance is still largely unclear, and some of the target antigens are present in other cells as well as neutrophils and thus are not strictly "ANCA."

Abstract
Given the variability in rate of radiographic resolution, it remains controversial to decide when to initiate an invasive diagnostic work-up for nonresolving or slowly resolving pulmonary infiltrates. In immunocompetent patients who present with classical features of CAP (i.e., fever, chills, productive cough, new pulmonary infiltrate), clinical response to therapy is the most important determinant for further diagnostic studies. Within the first few days, persistence or even progression of infiltrates on chest radiographs is not unusual. Defervescence, diminished symptoms, and resolution of leukocytosis strongly support a response to antibiotic therapy, even when chest radiographic abnormalities persist. In this context, observation alone is reasonable, and invasive procedures can be deferred. Serial radiographs and clinical examinations dictate subsequent evaluation. In contrast, when clinical improvement has not occurred and chest radiographs are unchanged or worse, a more aggressive approach is warranted. In this setting, we advise fiberoptic bronchoscopy with BAL and appropriate cultures for bacteria, legionella, fungi, and mycobacteria. When endobronchial anatomy is normal and there is no purulence to suggest infection, TBBs should be done to exclude noninfectious causes (discussed earlier) or infections attributable to mycobacteria or fungi. An aggressive approach is also warranted in patients who are clinically stable or improving when the rate of radiographic resolution is delayed. As discussed earlier, what constitutes excessive delay is controversial, and depends upon the acuity of illness, specific pathogen, extent of involvement (i.e., lobar versus multilobar), comorbidities, and diverse host factors. Stable infiltrates even 2 to 4 weeks after institution of antibiotic therapy does not mandate intervention provided patients are improving clinically. Invasive techniques can also be deferred when unequivocal, albeit incomplete, radiographic resolution can be demonstrated. Lack of at least partial radiographic resolution by 6 weeks, even in asymptomatic patients, however, deserves consideration of alternative causes (e.g., endobronchial obstructing lesions, or noninfectious causes). Fiberoptic bronchoscopy with BAL and TBBs has minimal morbidity and is the preferred initial invasive procedure for detecting endobronchial lesions or substantiating noninfectious causes. The yield of bronchoscopy depends on demographics, radiographic features, and pre-test likelihood. In the absence of specific risk factors, the incidence of obstructing lesions (e.g., bronchogenic carcinomas, bronchial adenomas, obstructive foreign body) is low. Bronchogenic carcinoma is rare in nonsmoking, young (< 50 years) patients but is a legitimate consideration in older patients with a history of tobacco abuse. Non-neoplastic causes (e.g., pulmonary vasculitis, hypersensitivity pneumonia, etc.) should be considered when specific features are present (e.g., hematuria, appropriate epidemiologic exposures). Ancillary serologic tests or biopsies of extrapulmonary sites are invaluable in some cases. In rare instances, surgical (open or VATS) biopsy is necessary to diagnose refractory or non-resolving "pneumonias."

Abstract
The co-existence of pulmonary hemorrhage and glomerulonephritis delineates a severe syndrome, often underestimated, resulting from several diseases and frequently associated with serum positivity for antineutrophil cytoplasmic antibodies (ANCA) or antiglomerular basement membrane (GBM) antibodies. The most common illness presenting as pulmonary-renal syndrome is systemic vasculitis. Moreover, the idiopathic pulmonary-renal syndrome is a distinctive clinicopathologic entity with different pathogenetic mechanisms. Tissue immunofluorescence studies are fundamental in distinguishing anti-GBM antibody-mediated forms from immune-complex-mediated and ANCA-associated forms. The type of glomerular or alveolar immunologic injury is the main factor determining the outcome and thus the prognosis of the pulmonary-renal syndrome. Development and improvement of appropriate serologic detection techniques have given reliable and early guidance for diagnosing these cases.

Abstract
Pulmonary involvement due to Wegener's granulomatosis (WG) can present radiologically either as diffuse infiltrates or as nodular and linear opacities. Clinical experience suggest that these radiological patterns are associated with different bronchoalveolar lavage (BAL) cell profiles, but this has not been examined formally. We compared the BAL cell profile in eight WG patients with diffuse infiltrates on chest X-ray, indicative of highly active pneumonitis, with corresponding findings in 37 patients with nodular, linear and focal low-attenuation infiltrates on high-resolution computed tomography (HRCT) which reflected low-grade, mainly interstitial disease. A control group was composed of 11 patients with pulmonary sarcoidosis. Diffuse infiltrates occurred in association with high systemic disease activity and featured a neutrophilic BAL profile in the presence of generally normal BAL lymphocytes. HRCT findings suggestive mainly of interstitial disease were associated with either a lymphocytic BAL cell profile or a normal cell pattern. Patients with a lymphocytic cell profile generally had a preferential elevation of CD4+ cells in the BAL in the presence of a normal CD4/CD8 ratio in the blood. This was a common feature of WG and pulmonary sarcoidosis. In conclusion, highly active pneumonitis and pulmonary disease of low or moderate activity in WG are associated with disparate BAL cell profiles. It remains to be examined whether the preferential elevation of CD4+ cells in the latter condition reflects a common pathogenetic role of this subset of cells in WG and pulmonary sarcoidosis.

Abstract
Antineutrophil cytoplasmic antibodies (ANCA) have been associated with systemic vasculitis for almost 15 years. Significant advances in our understanding of the ANCA phenomenon have occurred with recognition of broadening the spectrum of diseases associated with ANCA, identification of specific antigens recognized by ANCA, and development of antigen specific assays for clinical use. Nevertheless problems continue for the chest physician in interpretation of this test. Although antigen specific testing improves overall performance of the test, accurate assessment of pretest probability of disease is still important for effective use of ANCA testing.

Abstract
We report on a patient with myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) associated glomerulonephritis who had an elevated MPO-ANCA level and necrotizing crescentic glomerulonephritis on renal biopsy. She was treated by double filtration plasmapheresis and immunoadsorption plasmapheresis combined with steroid therapy and immunosuppressive agents. After plasmapheresis, the MPO-ANCA level decreased, and the cellular crescents were reduced. We conclude that plasmapheresis combined with steroid and immunosuppressive therapy may be useful to decrease the activity of MPO-ANCA associated crescentic glomerulonephritis.

Abstract
We report a patient with microscopic polyarteritis nodosa (mPN) and interstitial pneumonia, who was subjected to investigation by bronchoalveolar lavage (BAL), thoracic computerized tomography (CT) and gallium-67 citrate (67Ga) scintigraphy before and after administration of glucocorticoid and immunosuppressive agents. Renal function, renal histology, interstitial inflammation of the lung, and pulmonary function and histology improved cytoplasmic autoantibody (MPO-ANCA), which decreased with decreasing disease activity after starting treatment. Interstitial pneumonia may be associated with pulmonary capillaritis due to mPN. Methylprednisolone pulse therapy followed by oral prednisolone and immunosuppressive agents is considered to be an effective therapeutic strategy for combined mPN and interstitial pneumonia.

Abstract
A pANCA autoantibody (antineutrophil cytoplasmic antibody, perinuclear pattern) has been described in uveitis patients, but its correlation with systemic illnesses and the specific type of pANCA has not been defined. The goals of this study were to determine the (1) frequency of pANCA autoantibodies in uveitis, (2) systemic associations in the pANCA + uveitis patients, and (3) type of pANCA antigen recognized by the uveitis-associated autoantibody. Serum was obtained from 59 patients with anterior uveitis or panuveitis and from nonuveitis controls. A detailed medical and family history was obtained from each subject at the time of phlebotomy. Sera were screened by neutrophil ELISA to determine the frequency of ANCA positivity. Immunofluorescence assays were then used to differentiate cANCA from pANCA. The specificity of the pANCA + antibodies was further characterized by DNase 1 sensitivity and granule antigen ELISAs. ANCA antibodies were detected in 29% of all patients with panuveitis or anterior uveitis. In 41% of these ANCA + patients, serum antibody detected a perinuclear antigen that was sensitive in all cases to DNase 1. The majority of pANCA + uveitis patients were either HLA-B27 positive or had systemic evidence of immune-mediated diseases. Two pANCA + patients had no medical or family history of other immune-mediated diseases. This study identifies a subset of uveitis patients distinguished by expression of a specific pANCA marker antibody. The characteristics of this antibody are similar to the pANCA antibody present in most patients with ulcerative colitis. Expression of the pANCA autoantibody in uveitis patients is a susceptibility marker for other immune-mediated diseases.

Abstract
STUDY OBJECTIVES To demonstrate that pulmonary capillaritis and diffuse alveolar hemorrhage (DAH) occur and are isolated to the lung and therefore not part of systemic vasculitis at the time of the DAH episode in rheumatoid arthritis (RA) and mixed connective tissue disease (MCTD). DESIGN Lung biopsy specimens from patients with DAH were reviewed and those with the histologic features of pulmonary capillaritis were identified. SETTING The patients were selected from seven Denver-area general hospitals. PATIENTS Fifty-eight patients with biopsy specimen proved pulmonary capillaritis (1991 to 1997) were identified and classified according to disease. Three patients met the American Rheumatism Association criteria for RA and one patient fulfilled clinical and serologic criteria for MCTD. INTERVENTIONS All clinical, laboratory, and radiographic data on initial presentation and at follow-up periods were extracted from the charts of the four study patients. Histologic slides were reviewed and immunofluorescent studies of lung tissue were performed. MEASUREMENTS AND RESULTS All four patients had a connective tissue disease diagnosis prior to the DAH episode. Symptoms referable to pulmonary capillaritis were of short duration (2 to 14 days) and there was no clinical or serologic evidence for an accompanying systemic vasculitis, in particular glomeronephritis. Three patients, two with RA and one with MCTD, demonstrated pulmonary immune complex deposition. Three resolved their illness following IV methylprednisilone and cyclophosphamide therapy. One RA patient died following a myocardial infarction. In the three survivors, no further episodes of DAH have occurred after a mean of 24 months (range, 10 to 48 months). CONCLUSIONS To our knowledge, these are the first cases of DAH due to pulmonary capillaritis documented to complicate RA and MCTD. The capillaritis was not part of a systemic vasculitis at the time of the DAH episode, but rather represented an isolated small-vessel vasculitis of the lungs in this group of patients. Immune complex deposition may be involved in the pathogenesis.

Abstract
Wegener's granulomatosis is a distinct form of necrotizing granulomatous vasculitis which usually affects the kidneys and the upper and lower respiratory tracts. Unusual manifestations have also been reported, and these include colitis, urethritis and diabetes insipidus. We describe a case of Wegener's granulomatosis which presented with rapidly progressive renal insufficiency, sudden deafness, red eye, facial palsy, and complicated by uncommon manifestations that were diffuse pulmonary hemorrhage and thrombotic thrombocytopenic purpura.

Abstract
Patients with an established diagnosis of Wegener's granulomatosis (WG) sometimes undergo lung biopsy when the disease does not behave in the expected manner. Treatment affects the tissue reaction. The microscopic recognition of partially treated disease is important, as the absence of expected lesions may lead to nonspecific diagnoses and inappropriate management. The appearance of treated disease over time may offer insight into its histogenesis and natural history. We correlated clinical features and pulmonary histology in 20 patients with WG after they had been treated with corticosteroids or cyclophosphamide or both. All patients had inflammatory or fibrotic pulmonary disease resulting from WG, but only 4 (20%) had macronodular necrosis typical of WG. Serum antineutrophil cytoplasmic antibody (ANCA) was elevated in all patients in whom it was measured. We divided the pathological findings into (1) vasculitis, (2) extravascular necrosis, (3) bronchiolitis, and (4) other lesions, and further divided them into (a) diagnostic for active disease, (b) suspicious for active disease, (c) suspicious for healing disease, (d) suspicious for residual disease, and (e) possible disease. Diagnostic or suspicious vascular lesions occurred in 15 patients (75%) and included granulomatous vasculitis, capillaritis or suspicious capillaritis, and neutrophilic vasculitis. Diagnostic or suspicious extravascular lesions occurred in 12 patients (60%) and included palisading granuloma, microabscess, macronodular pathergic necrosis, giant cell nodules, and micronodular scars. The giant cell nodules and nodular scars were an unusual healing pattern of palisading granulomas. Diagnostic bronchiolar lesions occurred in 1 patient (6%) and suspicious lesions in 13 patients (65%), including three novel patterns of bronchiolitis fibrosa (BF): (1) BF with giant cells, (2) BF with hemosiderin, and (3) BF with micronodular scars. Other features related to WG included diffuse alveolar damage, peculiar alveolar fibrin, interstitial fibrosis, pneumonitis resembling usual interstitial pneumonitis, and lipoid pneumonia. Classic necrotic nodules and vasculitis of WG should not be anticipated after therapy, but the diagnosis of pulmonary WG after treatment may be made if the effects of treatment on histology are considered. Changes in anticipated histology are found after therapy as short as 6 days. The histology typically has muted features. BF develops in most patients and may reflect a salutary effect of therapy. Palisading granuloma may convert to giant cell nodule or micronodular scar. Interstitial fibrosis is common, and pneumonitis resembling usual interstitial pneumonitis can develop. If only healing or residual disease is encountered, one should search further clinically and pathologically for active disease. Dampened inflammatory lesions represent smoldering disease that presumably needs additional therapy. Scarring presumably represents successfully treated but permanent disease.

Abstract
Pulmonary vascular inflammatory disorders may involve all components of the pulmonary vasculature, including capillaries. The principal histopathologic features of pulmonary capillaritis include capillary wall necrosis with infiltration by neutrophils, interstitial erythrocytes, and/or hemosiderin, and interalveolar septal capillary occlusion by fibrin thrombi. Immune complex deposition is variably present. Patients often present clinically with diffuse alveolar hemorrhage, which is characterized by dyspnea and hemoptysis; diffuse, bilateral, alveolar infiltrates on chest radiograph; and anemia. Pulmonary capillaritis has been reported with variable frequency and severity as a manifestation of Wegener's granulomatosis, microscopic polyarteritis, systemic lupus erythematosus, Goodpasture's syndrome, idiopathic pulmonary renal syndrome, Behçet's syndrome, Henoch-Schönlein purpura, IgA nephropathy, antiphospholipid syndrome, progressive systemic sclerosis, and diphenylhydantoin use. In addition to history, physical examination, and routine laboratory studies, certain ancillary laboratory tests, such as antineutrophil cytoplasmic antibodies, antinuclear antibodies, and antiglomerular basement membrane antibodies, may help diagnose an underlying disease. Diagnosis of pulmonary capillaritis can be made by fiberoptic bronchoscopy with transbronchial biopsy, but thoracoscopic biopsy is often employed. Since many disorders can result in pulmonary capillaritis with diffuse alveolar hemorrhage, it is crucial for clinicians and pathologists to work together when attempting to identify an underlying disease. Therapy depends on the disorder that gave rise to the pulmonary capillaritis and usually includes corticosteroids and cyclophosphamide or azathioprine. Since most diseases that result in pulmonary capillaritis are treated with immunosuppression, infection must be excluded aggressively.
