Anti-glomerular basement membrane (anti-GBM) disease usually presents as rapidly progressive glomerulonephritis, and, when accompanied with pulmonary hemorrhage, it is called Goodpasture's syndrome. Anti-neutrophilic cytoplasmic antibodies (ANCA) may co-exist with anti-GBM antibodies. In most of these "double positive" cases, ANCA is specific for myeloperoxidase (p-ANCA). We report a rare case of a critically ill patient c-ANCA-associated double-positive Goodpasture's syndrome with concomitant tuberculosis that was successfully treated with immunosuppression, plasmapheresis and anti-tuberculous therapy (ATT). A 32-year-old gentleman with a 15 pack-year smoking history presented with massive hemoptysis, respiratory failure and oliguria. Laboratory investigation revealed anemia, elevated creatinine and active urinary sediment. Chest X-ray revealed bilateral pulmonary infiltrates. Broad-spectrum antibiotics and intravenous corticosteroids were started. Bronchoscopy showed alveolar hemorrhage and smears from bronchial lavage from both lungs were positive for acid fast bacillus (AFB). Vasculitis work-up revealed high titers of c-ANCA and anti-GBM antibodies. Kidney biopsy revealed crescents in >50% glomeruli on light microscopy. Immunofluorescence showed linear deposition of IgG and C3. The patient received pulse methylprednisone for three days followed by oral prednisone and ATT. In addition, he also underwent nine sessions of plasmapheresis. Oral Cyclophosphamide was added on Day 10. The patient showed remarkable recovery as his lung fields cleared and his kidney function got stabilized. Cyclophosphamide was continued for three months and then switched to azathioprine. At six months, the creatinine is 1.2 mg/dL, with minimal proteinuria and a normal chest X-ray. To the best of our knowledge, this is the only reported case of double-positive Goodpasture's syndrome (c-ANCA and anti GBM) with active tuberculosis treated successfully.
