Abstract
A 33-year-old woman with past history of Sjögren's syndrome and systemic lupus erythematosus presented with dyspnea and syncope secondary to pulmonary hypertension. After progressive symptoms over 4 years, she received bilateral lung transplantation. Histopathology of the explanted lungs showed isolated pulmonary amyloid light-chain amyloidosis and pulmonary cysts. No evidence of systemic amyloidosis was found at the time of transplantation. Seven years post lung transplantation, she remains well with no evidence of systemic amyloidosis recurrence.

Abstract
Amyloid A (AA) amyloidosis occurs secondary to long-standing inflammation and causes nephropathy and various internal manifestations, which leads to mortality. It is very rare in some rheumatic diseases, such as systemic lupus erythematosus (SLE). Therefore, there are few articles that report AA amyloidosis in SLE. This article focuses on the previously reported cases of 24 patients with SLE that are complicated by AA amyloidosis, and on the underlying mechanisms.

Abstract
Secondary amyloidosis is an unusual complication of systemic lupus erythematosus (SLE). We report the case of a 60-year-old woman with SLE and secondary amyloidosis who developed class III proliferative lupus nephritis 13 years after the onset of amyloid nephropathy. The patient was treated with mycophenolate mofetil (1.5 g/day) with a significant improvement in proteinuria.

Abstract
We report autopsy findings in an 83-year-old woman with myeloperoxidase-type anti-neutrophil cytoplasmic antibody (MPO-ANCA)-positive microscopic polyangiitis and systemic AA amyloidosis. With a diagnosis of MPO-ANCA-related microscopic polyangiitis, the patient was treated with corticosteroids, but she died of intractable enteritis. Autopsy showed inactive vasculitis affecting small arteries in kidney, lung, intestinal tract, and skeletal muscle. Gastrointestinal viscera were thickened, and AA-amyloid was demonstrated in arterioles and surrounding tissues. Amyloidosis also involved heart, kidney, gallbladder, pancreas, salivary gland, and subcutis. ANCA-positive microscopic polyangiitis appears to have been the likely cause of this patient's AA-amyloidosis.

Abstract
PURPOSE OF REVIEW This review evaluates the role of kidney biopsy as a tool in the diagnosis, prognostication and therapeutic management of lupus nephritis. The renal biopsy is the only method available for diagnosing and classifying lupus nephritis. However, disagreements persist regarding the appropriate role of a renal biopsy in the management and identification of predictors of short and long-term outcomes. RECENT FINDINGS Recent modifications to the classification of lupus nephritis, the emergence of newer scoring indices, and the availability of a variety of therapeutic options predicate a reassessment of the role of the renal biopsy in the management of lupus nephritis, especially for high-risk patients. SUMMARY Despite some controversy, the renal biopsy has been shown to provide information over and above that provided by the clinical variables, and remains a pivotal element in optimizing therapy and the rational management of lupus nephritis.

Abstract
A young male presented with oral ulceration for two years; swelling face and feet of seven days duration; diffuse goiter without signs of thyroid disease; normocytic normochromic anemia, thrombocytopenia, deranged renal functions, albuminuria of 2.5 g/24h with active urinary sediment. ANA and anti-ds DNA were positive, sonography of abdomen suggested medical renal disease. Testing for HIV, HBV, VDRL, CRP, rheumatoid factor, p-ANCA and c-ANCA were negative. Thyroid hormone assays were normal. Kidney biopsy done to stage lupus nephritis did not show any evidence of lupus involvement but staining for SAA amyloid was positive. Subsequent biopsies from the liver and rectum also stained positive for amyloid. Diagnosis of "Systemic lupus erythematosus with renal and systemic secondary amyloidosis with euthyroid diffuse goiter" was made. The case is being reported and discussed because of the interesting and rare association between amyloidosis and systemic lupus erythematosus.

Abstract
Renal biopsy specimens from patients with systemic lupus erythematosus (SLE) rarely show changes that are pathogenetically and morphologically unrelated to SLE. The morphology and behavior of these nonlupus nephritides are not well known. Two hundred fifty-two renal biopsies performed on 224 patients with SLE collected from 3,036 native kidney biopsies performed between 1975 and 1998 were reviewed, and those that showed nonlupus nephritides (index biopsies) were selected for studies. Thirteen biopsy specimens with nonlupus nephritides were identified in 13 patients, who belonged to 3 clinically distinct groups. Group I included 6 patients in whom SLE was diagnosed at the time of index biopsies. The index biopsies in these patients showed focal segmental glomerusclerosis (FSGS; 3 cases), Immunoglobulin (Ig) M nephropathy (1 case), and thin basement membrane disease (1 case). The diagnostic features for FSGS included segmental sclerosis involving at least 1 glomerulus, absence of lupus nephritis or other conditions that may cause nonspecific segmental sclerosis of glomeruli such as ischemia or nephrosclerosis, and nephrotic-range proteinuria. There was uniform, global, diffuse and marked thinning of the glomerular basement membrane in the case of thin basement membrane disease. Group II included 3 patients in whom SLE was diagnosed 2 to 9 years before the time of index biopsies and SLE was active at the time of biopsy. The index biopsies in these patients showed FSGS (2 cases) and hypertensive nephrosclerosis (1 case). Group III included 4 patients in whom SLE was diagnosed 5 to 36 years before the time of index biopsies and SLE was inactive at the time of biopsy. The index biopsies in these patients showed 1 case each of amyloidosis, FSGS, hypertensive nephrosclerosis, and allergic acute tubulointerstitial nephritis. Previous renal biopsies, performed in 5 patients, showed IgM nephropathy (1 case), diffuse proliferative lupus GN (1 case), focal proliferative lupus GN (1 case), and mesangial proliferative lupus GN (2 cases). Follow-up biopsies, performed in 3 patients, confirmed the diagnosis of FSGS (2 cases) and hypertensive nephrosclerosis (1 case) noted in the index biopsies. Nonlupus nephritides may occasionally be encountered in SLE patients, regardless of clinical or serologic disease activity. These renal lesions display a broad morphologic spectrum in which FSGS seems most frequent. Renal biopsy plays a crucial role in identifying these lesions, which may have prognostic and therapeutic implications distinct from those of lupus nephritis.

Abstract
The lack of sensitive and relatively non-invasive measures has hampered monitoring the clinical course of spontaneously developing colitis in IL-2-deficient (-/-) mice. We selected (i) to study the correlation of the acute phase plasma proteins serum amyloid A (SAA) and serum amyloid P component (SAP) levels with colonic disease and (ii) to characterize the amyloidosis in the IL-2(-/-)animals. IL-2(-/-)mice exhibited increasing severity of gross intestinal inflammation with age, confined to the distal colon. Histologically, the colonic disease score increased serially in IL-2(-/-)animals. Wild-type mice showed no activity, while 16-week-old IL-2(+/-)animals had minimal colitis with small ulcers and lamina propria inflammatory infiltrate. Periportal hepatitis was present and positive Congo red staining indicated amyloidosis of the liver and spleen in 16 week IL-2(-/-)mice. SAA immunostaining in the liver and spleen was increased in the 8 week and 16 week IL-2(-/-)and 16 week IL-2(+/-)animals indicating AA amyloid deposits. Plasma SAA and SAP levels were markedly elevated, and generally preceded the onset of colitis and reflected its severity. Northern analysis showed markedly increased SAA expression in the liver and intestine of IL-2(-/-)and intestine of IL-2(+/-)16-week-old animals. Increased intestinal expression of SAA3 (lamina propria macrophages) indicates local inflammation in IL-2(+/-)animals at 16 weeks. Treatment of 3-week-old animals with systemic IL-2 or IL-1 receptor antagonist (IL-1ra) delayed inflammation, postponed the increase in SAA levels and minimized disease onset. These results further demonstrate that IL-2 plays a significant role in normal immune responses in the body and that plasma SAA levels both reflect colonic disease severity and may indicate subclinical disease in both IL-2(-/-)and IL-2(+/-)mice. Furthermore. The mechanism of IL-2-deficient induced colitis appears to be mediated in part through the increase in IL-1. In addition, the IL-2(-/-)mouse of spontaneous enterocolitis may provide a unique system for studying spontaneously developing AA amyloidosis.

Abstract
Renal involvement is frequent in systemic lupus erythematosus (SLE). This lesion, termed lupus nephritis, has been reported clinically in at least 50% of the patients. It is generally assumed that in patients with SLE, renal abnormalities detected clinically are caused by lupus nephritis, especially lupus glomerulonephritis (GN). Thus, renal biopsy is performed not for diagnostic purposes, but rather for determining the type and extent of renal involvement. However, clinically significant renal abnormalities unrelated to lupus nephritis have rarely been described in patients with SLE. The reported case serves to emphasize this consideration. The patient was a 41-year-old woman who presented 11 years previously with severe hypertension, nephrotic syndrome, and a serum creatinine level of 2.9 mg/dL. Renal biopsy showed membranous GN and ischemic damage. After a prolonged remission induced by steroids and cyclophosphamide, the patient presented with nephrotic syndrome and a serum creatinine level of 2.1 mg/dL. Although she was normotensive at that time, there were features of SLE. Repeated renal biopsy showed focal segmental glomerulosclerosis without the changes of membranous GN or any type lupus GN. This case illustrates two interesting observations, ie, resolution of membranous GN and nonlupus renal lesions in patients with SLE.
