The switch from proteasome to immunoproteasome is increased in circulating cells of patients with fast progressive immunoglobulin A nephropathy and a…
2021
The proteasome to immunoproteasome (iPS) switch consists of β1, β2 and β5 subunit replacement by low molecular weight protein 2 (LMP2), LMP7 and multicatalytic endopeptidase-like complex-1 (MECL1) subunits, resulting in a more efficient peptide preparation for major histocompatibility complex 1 (MHC-I) presentation. It is activated by toll-like receptor (TLR) agonists and interferons and may also be influenced by genetic variation. In a previous study we found an iPS upregulation in peripheral cells of patients with immunoglobulin A nephropathy (IgAN). We aimed to investigate in 157 IgAN patients enrolled through the multinational Validation Study of the Oxford Classification of IgAN (VAL…
Anti-glomerular basement membrane antibody-mediated glomerulonephritis due to glue sniffing
1987
A 16-year-old girl developed rapidly progressive glomerulonephritis and renal failure. The disease was associated with high titres of antiglomerular basement membrane antibodies in serum, linear deposits of immunoglobulin G and diffuse epithelial crescents on renal biopsy. Past history revealed heavy smoking and deliberate sniffing of Pattex glue, a mixture of hydrocarbons which possibly may affect the structure of glomerular basement membrane. After treatment by repeated plasmapheresis and drug immunosuppression autoantibodies disappeared from serum but renal function was not influenced. Renal damage is a potential hazard for glue sniffing adolescents.
Tubulointerstitielle-Nephritis-Uveitis-Syndrom (TINU-Syndrom)
1995
Abstract For 10 weeks a 25-year-old man had been suffering from tiredness, fatigue, nausea and a 16 kg weight loss. Erythrocyte sedimentation rate (83/133 mm), serum C-reactive protein (5.5 mg/dl) and creatinine (5.05 mg/dl) were all elevated. He also had proteinuria (1120 mg daily), sterile leukocytosis and a creatinine clearance of 10 ml/min. Renal biopsy showed interstitial nephritis and bone marrow biopsy revealed non-caseous epithelioid-cell granulomas. 14 days after admission he developed acute iritis in the right eye. Other causes having been excluded, the diagnosis of tubulo-intestinal nephritis with uveitis (TINU syndrome) was made. The clinical symptoms and laboratory findings imp…
Efficacy of epidural anesthesia for retroperitoneoscopic renal biopsy
2000
Laparoscopic procedures are performed using general anesthesia due to the perceived limitations of regional anesthesia in the upper abdomen and retroperitoneum. We present our initial experience with epidural anesthesia for retroperitoneal laparoscopic renal biopsy.
Mitomycininduziertes hämolytisch-urämisches Syndrom
2003
HISTORY AND CLINICAL FINDINGS A 58-year-old patient suffered from rapidly progressing renal insufficiency and 11 kg weight-loss three months after adjuvant treatment of a carcinoma of the lower bowel (G 2 T 3 N 1 M 0 ) with mitomycine C. At the point of hospitalisation the patient was anuric while suffering from pulmonary oedema, hemolytic anemia and thrombocytopenia. INVESTIGATIONS Computed tomography and bronchial endoscopy showed pulmonary haemorrhage. Recurrence of carcinoma or metastases were excluded. Renal biopsy revealed mesangiolysis and concentric intimaproliferation (onion skinning). Beside haemolytic anaemia and fragmentocytes toxic damage of the bone marrow was found. TREATMENT…
Per-protocol repeat kidney biopsy portends relapse and long-term outcome in incident cases of proliferative lupus nephritis
2019
Abstract Objectives In patients with LN, clinical and histological responses to treatment have been shown to be discordant. We investigated whether per-protocol repeat kidney biopsies are predictive of LN relapses and long-term renal function impairment. Methods Forty-two patients with incident biopsy-proven active proliferative (class III/IV±V) LN from the database of the UCLouvain were included in this retrospective study. Per-protocol repeat biopsies were performed after a median [interquartile range (IQR)] time of 24.3 (21.3–26.2) months. The National Institutes of Health activity index (AI) and chronicity index (CI) scores were assessed in all biopsies. Results Despite a moderate corre…
IgE in patients with glomerulonephritis and minimal-change nephrotic syndrome
1979
Serum levels of IgE were studied in 30 children with minimal-change nephrotic syndrome and 32 children with mesangioproliferative glomerulonephritis during different stages of the disease and treatment. In addition, tissue obtained by renal biopsy was investigated by immunofluorescence histology; no deposits of IgE could be found. The serum IgE levels, however, were increased, particularly in patients with minimal-change nephrotic syndrome. It is concluded that IgE does not play a pathogenic role in the development of the renal disease, but that increased IgE levels are an indication of a disturbance of the immune system.
Development of systemic lupus erythematosus in a patient with selective complete C1q deficiency
1997
A 7-year-old male with recurrent erythematous and desquamated skin lesions and respiratory infections was diagnosed as selective complete C1q deficiency following detailed studies of the complement system. His asymptomatic sister also had selective complete C1q deficiency. During a follow up period of 3 years, his skin lesions persisted, he suffered from recurrent bronchopneumonias and glomerulonephritis developed. Renal function deteriorated with the appearance of anti-DNA antibodies. Renal biopsy was consistent with systemic lupus erythematosus. The patient was treated with immunosuppressive drugs, but died of renal failure. It is postulated that in this patient defective clearance of ant…
Epistaxis and systemic disease
2008
Abstract We report the case of a 77-year-old man who presented nasal obstruction sensation and epistaxis. Otorhinolaryngologic examination revealed occupation of the left nasal passage and the left maxillary sinus by an inflammatory tumour, the biopsy results of which were inconclusive. While diagnostic tests were being carried out, the patient presented a severe systemic condition consisting mainly of anemia, acute renal failure, and cavitated diffuse bilateral lung infiltrates. In the light of the results of anti-neutrophilic cytoplasmic antibodies and renal biopsy, Wegener's granulomatosis was diagnosed and treatment for the disease was instituted, with a favourable response. Finally, cl…
Interstitielle Nephritis bei atypischer Manifestation eines Sj�gren's Syndrom
1980
A patient was observed with interstitial nephritis which resulted in renal tubular acidosis (distal type), tubular proteinuria and defective urinary concentrating ability in the absence of edema, elevated arterial blood pressure, glomerular proteinuria or abnormal urinary sediment. The presence of interstitial nephritis was established by renal biopsy which showed dense infiltrates in the interstitium, interstitial fibrosis and thickening and splitting of the pericapillary basal membranes. Immunofluorescence was non contributory. Extrarenal symptoms were discrete (arthralgia of both hands, Raynaud's syndrome upon cold exposure). Mixed connective tissue disease (MCTD) was suspected because o…
