1/104. Renal granulomatous sarcoidosis in childhood: a report of 11 cases and a review of the literature.We analysed retrospectively 11 children with renal granulomatous sarcoidosis confirmed by renal histology in order to describe the course and prognosis of the disease. Symptomatic sarcoidosis was diagnosed at a mean age of 10.1 years. Nine children had renal involvement at the time of diagnosis. In the course of the disease, nine patients developed renal failure and mild proteinuria, seven had transient sterile leukocyturia, four showed microscopic haematuria, seven had a urinary concentrating defect, and enlarged kidneys were seen in three patients. One child had hypercalcaemia and hypercalciuria, none had hypertension. light microscopy of the kidney showed interstitial infiltration by mononuclear cells in all children, interstitial fibrosis in nine patients, epithelioid granulomas in seven, tubular involvement in eight, and mild glomerular involvement in seven patients. Renal immunofluorescence was negative. Ten children received prednisone for 1-11 years. After a mean follow up of 5.5 years, three patients had entered end-stage renal failure and one had chronic insufficiency after interruption of medical supervision and prednisone therapy. CONCLUSION: Renal failure, proteinuria, leukocyturia, haematuria, and concentration defect are the prominent features of renal granulomatous sarcoidosis in children. Steroid therapy, adjusted according to disease activity, may prevent end-stage renal failure.- - - - - - - - - - ranking = 1keywords = interstitial (Clic here for more details about this article) |
2/104. sarcoidosis associated with multiple large pulmonary nodules.Parenchymal manifestations of pulmonary sarcoidosis include a diffuse, symmetric, reticulonodular interstitial pattern, a fibrotic pattern, and an acinar pattern. Large pulmonary nodules in sarcoidosis are rare, and their frequency (> 1 cm in diameter) has been estimated at 2-4%. We report a rare case of sarcoidosis associated with large bilateral pulmonary nodules. These nodules reached up to 7 cm in diameter, which is larger than any others reported previously. Furthermore, these nodular lesions developed within only 6 months of normal chest X-ray results and were not found to accompany bilateral hilar lymph adenopathy, which is observed in the usual course of sarcoidosis. As described above, this case of pulmonary sarcoidosis was significant not only in terms of the large size of the nodules but also the unique chest X-ray course.- - - - - - - - - - ranking = 0.5keywords = interstitial (Clic here for more details about this article) |
3/104. Granulomatous interstitial nephritis in extrapulmonary sarcoidosis.sarcoidosis is a multisystem disorder in which the lungs or intrathoracic lymph nodes are involved in more than 90% of patients with the disease. It occasionally involves kidneys most commonly due to disordered calcium metabolism. Granulomatous interstitial nephritis is a distinct renal pathology in sarcoidosis. Renal dysfunction due to granulomatous interstitial nephritis is rare. We recently encountered a sarcoidosis patient without hypercalcemia and any evidence of pulmonary involvement which is distinctly unusual.- - - - - - - - - - ranking = 65.86762979keywords = interstitial nephritis, nephritis, interstitial (Clic here for more details about this article) |
4/104. Sarcoid-like pulmonary disorder in human immunodeficiency virus-infected patients receiving antiretroviral therapy.We report two cases of hiv-infected patients who presented with diffuse interstitial micronodular lesions on chest X-ray after institution of protease inhibitor-containing highly active antiretroviral therapy (HAART). Granulomatous pulmonary disorder mimicking sarcoidosis was diagnosed on histopathological studies revealing noncaseating granuloma and bronchoalveolar lavage analysis showing an intense CD4( ) lymphocyte alveolitis. Causative agents such as infectious organisms and environmental compounds were excluded. The relationship between sarcoid-like reaction and immune reconstitution under HAART is discussed.- - - - - - - - - - ranking = 0.5keywords = interstitial (Clic here for more details about this article) |
5/104. Systemic sarcoidosis and cutaneous lymphoma: is the association fortuitous?The association of systemic sarcoidosis and malignant lymphoma is known as the 'sarcoidosis-lymphoma syndrome'. Cutaneous involvement is rare in this syndrome. We report a 52-year-old woman who was diagnosed as having tumour-stage mycosis fungoides. Complete remission was achieved by combination therapy consisting of isotretinoin, interferon (IFN) alpha, electron beam irradiation, photochemotherapy and topical corticosteroids. Three years later, the patient developed systemic sarcoidosis characterized by yellowish papules on the abdominal wall and the eyelids that histologically revealed non-caseating granulomas, multiple fine-nodular interstitial pulmonary infiltrates on chest X-ray, hilar lymphadenopathy, decreased vital capacity and increased lymphocyte count in bronchoalveloar lavage fluid. As opposed to most of the reported cases, in our patient the manifestation of cutaneous lymphoma preceded the diagnosis of systemic sarcoidosis. We review the cases reported in the literature and discuss a possible causal and temporal relationship as well as the role of IFN alpha in the development of sarcoidosis.- - - - - - - - - - ranking = 0.5keywords = interstitial (Clic here for more details about this article) |
6/104. Renal sarcoidosis with superimposed postinfectious glomerulonephritis presenting as acute renal failure.We describe two patients with sarcoidosis with lesions of granulomatous interstitial nephritis (GIN) and postinfectious glomerulonephritis (GN). Both patients presented with heavy proteinuria, hematuria, and renal failure. Renal histology in both showed GIN and glomerular changes of proliferative GN with hump-like subepithelial deposits by electron microscopy of postinfectious GN. Antecedent history of pneumonia was present in one, and ASO titer was elevated in the other. The proteinuria and azotemia improved in both with steroid therapy. Reports of "postinfectious" or diffuse proliferative GN in patients with sarcoidosis are rare. The authors are unaware of reports of concomitant sarcoid GIN and postinfectious GN. Although acute renal insufficiency or failure can occur with GIN or other more common renal lesions primary glomerular disease should be considered in patients with sarcoidosis who present with renal dysfunction. This is a US government work.

7/104. sarcoidosis with granulomatous interstitial nephritis: report of three cases.Three cases of sarcoidosis with granulomatous interstitial nephritis are reported. patients were all male and over 50 years of age. They simultaneously had evidence of multiorgan involvement of sarcoidosis including lung and skin and/or eye. In addition, distinct features were found in each case: a granulomatous infiltration mimicking unilateral renal tumor (case 1); renal insufficiency solely due to granulomatous interstitial nephritis (case 2); and renal insufficiency with calcemic nephropathy and granulomatous interstitial nephritis (case 3). prednisolone therapy resulted in disappearance of the pseudotumor in case 1 and partial improvement of renal function in cases 2 and 3. In cases 2 and 3, however, plasma creatinine did not return to normal values and a second renal biopsy in case 2 demonstrated residual interstitial fibrosis and few granulomas, suggesting that steroid therapy did not achieve complete reversal of changes.- - - - - - - - - - ranking = 77.345568088334keywords = interstitial nephritis, nephritis, interstitial (Clic here for more details about this article) |
8/104. diagnosis of cardiac sarcoidosis and evaluation of the effects of steroid therapy by gadolinium-DTPA-enhanced magnetic resonance imaging.BACKGROUND: Cardiac involvement is an important prognostic factor in patients with sarcoidosis. In this study, we evaluated the usefulness of gadolinium-DTPA (diethylene triamine pentaacetic acid)-enhanced magnetic resonance imaging (Gd-MRI) for diagnosing cardiac sarcoidosis and evaluating the effects of steroid therapy.methods: Sixteen patients with sarcoidosis diagnosed by histology or by Japanese Ministry of health and Welfare criteria for cardiac sarcoidosis underwent Gd-MRI with a 1.5-Tesla superconducting magnet system using a T1-weighted spin-echo sequence.RESULTS: Gd-MRI showed localized enhancement of signal intensity, indicating interstitial edema, in the left ventricle in 8 of the 16 patients. Two patients with enhancement also had thinning of the left ventricular septal wall. After 1 month of prednisolone therapy (60 mg every other day or 30 to 40 mg every day), the localized high-intensity signals were markedly diminished in all 8 patients.CONCLUSIONS: Images of the heart obtained by Gd-MRI may reflect active inflammation with interstitial edema in patients with sarcoidosis. Gd-MRI may be a useful noninvasive method for early detection of cardiac sarcoidosis and for evaluating the effects of steroid therapy.- - - - - - - - - - ranking = 1keywords = interstitial (Clic here for more details about this article) |

10/104. A rare cause of focal segmental glomerulosclerosis: sarcoidosis.A 58-year-old female patient diagnosed as having sarcoidosis 23 years ago developed nephrotic syndrome. No pathology was found which could explain this, so it was attributed to her sarcoidosis. Renal biopsy showed global and segmental sclerosis. The occurrence of focal segmentary glomerulosclerosis in a case of sarcoidosis is rare. In systemic sarcoidosis it is thought that T-cell dysfunction may play a role in the pathogenesis of glomerulonephritis. When treatment is considered, corticosteroid therapy may be used according to the clinical status at diagnosis as well as on follow-up of the patient.- - - - - - - - - - ranking = 5.1384734520339keywords = nephritis (Clic here for more details about this article) |
