          ABSTRACT

          CONTEXT:

          Anti-glomerular basement membrane (anti-GBM) antibody syndrome is characterized by deposition of anti-GBM antibodies on affected tissues, associated with glomerulonephritis and/or pulmonary involvement. This syndrome has been described in association with other autoimmune disorders, but as far as we know, it has not been described in association with dermatomyositis and psoriasis.

          CASE REPORT:

          A 51-year-old man with a history of dermatomyositis and vulgar psoriasis presented with a condition of sensitive-motor polyneuropathy of the hands and feet, weight loss of 4 kg, malaise and fever. On admission, he had been making chronic use of cyclosporin and antihypertensive drugs for three months because of mild arterial hypertension. Laboratory tests showed anemia and leukocytosis, elevated serum urea and creatinine and urine presenting proteinuria, hematuria, leukocyturia and granular casts. The 24-hour proteinuria was 2.3 g. Renal biopsy showed crescentic necrotizing glomerulonephritis with linear immunoglobulin G (IgG) deposits on the glomerular basement membrane by means of direct immunofluorescence, which were suggestive of anti-GBM antibodies. The patient was then treated initially with methylprednisolone and with monthly cyclophosphamide in the form of pulse therapy.

          RESUMO

          CONTEXTO:

          A síndrome do anticorpo anti-membrana basal glomerular (anti-MBG) é caracterizada pela deposição de anticorpos anti-MBG em tecidos afetados, associada à glomerulonefrite e/ou ao envolvimento pulmonar. Essa síndrome já foi descrita em associação a outras doenças autoimunes, mas até onde conhecemos, não há relatos de sua associação com dermatomiosite e psoríase.

          RELATO DE CASO:

          Um homem de 51 anos com antecedentes de dermatomiosite e psoríase vulgar apresentou quadro de polineuropatia sensitivo-motora de mãos e pés, perda de 4 kg, adinamia e febre. À admissão estava em uso crônico de ciclosporina e de anti-hipertensivos há três meses devido a hipertensão arterial leve. Exames laboratoriais mostraram anemia e leucocitose, creatinina e ureia séricas elevadas e urina com proteinúria, hematúria, leucocitúria e cilindros granulosos. A proteinúria de 24 horas foi de 2,3 g. A biópsia renal revelou uma glomerulonefrite crescêntica necrotizante com depósitos lineares de imunoglobulina G (IgG) na MBG à imunofluorescência, sugestivos de anticorpos anti-MBG. O paciente foi então tratado inicialmente com metilprednisolona e com ciclofosfamida mensalmente na forma de pulsoterapia.

            Coexistence of anti-glomerular basement membrane antibodies and myeloperoxidase-ANCAs in crescentic glomerulonephritis.

            In a substantial proportion of patients with crescentic glomerulonephritis (CGN), both anti-glomerular basement membrane (GBM) antibodies and antineutrophil cytoplasmic antibodies (ANCAs) with specificity for myeloperoxidase (MPO-ANCA) are detected. In the present study, we questioned whether histological and clinical features of patients with both ANCA and anti-GBM antibodies differ from those of patients with either ANCA or anti-GBM alone. We reviewed the Limburg renal biopsy registry (1978 to 2003; n = 1,373) for cases of CGN. The presence of linear fluorescence on renal biopsy and the presence of ANCA and/or anti-GBM antibodies were measured. Subsequently, we assessed patient characteristics and follow-up and compared histological findings among the different groups. We identified 46 MPO-ANCA-positive, 10 double-positive, and 13 anti-GBM-positive patients. Mean ages were 63, 64, and 52 years (P = 0.04), and serum creatinine levels were 5.0, 10.3, and 9.6 mg/dL (445, 910, and 850 micromol/L), respectively (P = 0.01). Granulomatous periglomerular inflammation was found in either MPO-ANCA- or double-positive patients, but not in anti-GBM-positive patients with CGN without MPO-ANCAs. Patient survival among the 3 groups was different, although not statistically significant (log rank P = 0.17, with 75%, 79%, and 100% alive at 1 year, respectively). Renal survival analysis showed significant differences among the 3 groups (P = 0.04, with 65%, 10%, and 15% off dialysis therapy at 1 year, respectively). In patients with both anti-GBM antibodies and MPO-ANCAs, histological findings differ from those of patients with anti-GBM antibodies only. However, renal survival in these patients is not better than that in anti-GBM-positive patients and is worse compared with patients with MPO-ANCAs only.

              Antineutrophil cytoplasmic antibodies.

              Much like other autoantibodies (eg, anti-double stranded DNA in systemic lupus erythematosus or antiglomerular basement membrane antibodies in Goodpasture's syndrome), antineutrophil cytoplasmic antibodies (ANCA) have provided doctors with a useful serological test to assist in diagnosis of small-vessel vasculitides, including Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome, and their localised forms (eg, pauci-immune necrotising and crescentic glomerulonephritis). 85-95% of patients with Wegener's granulomatosis, microscopic polyangiitis, and pauci-immune necrotising and crescentic glomerulonephritis have serum ANCA. ANCA directed to either proteinase 3 or myeloperoxidase are clinically relevant, yet the relevance of other ANCA remains unknown. Besides their diagnostic potential, ANCA might be valuable in disease monitoring. In addition, data seem to confirm the long-disputed pathogenic role of these antibodies. Present treatments for ANCA-associated vasculitis are not free from side-effects and as many as 50% of patients relapse within 5 years. Accurate understanding of the key pathogenic points of ANCA-associated vasculitis can undoubtedly provide a more rational therapeutic approach.
