Recurrent diffuse pulmonary hemorrhage with minor kidney lesions
Abstract:
This case report concerns a 14-year-old boy with a 3 month history of dyspnea and iron deficiency anemia. On admission he had hemoptysis and bilateral pulmonary shadows. Transbronchial lung biopsies showed linear deposits of IgG and C3 in the alveolar basement membrane, but no anti-GBM antibodies were observed in serum or kidney biopsy. The ratio of the T cell subpopulations T4/T8 in peripheral blood was in the early stage, 5 and, thus, elevated. The patient was given prednisolone 1 to 0.25 mg/kg and cyclophosphamide 2 mg/kg with temporary cessation of pulmonary bleeding. Hemoptysis recurred and plasma exchange was performed with success.
Insights
This case report details a teen with lung bleeding and anemia. Treatment involved steroids, chemotherapy, and plasma exchange, successfully managing pulmonary hemorrhage.
Area of Science:
- Pulmonology
- Nephrology
- Immunology
Background:
- A 14-year-old male presented with a 3-month history of dyspnea and iron deficiency anemia.
- Admission findings included hemoptysis and bilateral pulmonary shadows, suggesting significant respiratory compromise.
Observation:
- Transbronchial lung biopsies revealed linear immunoglobulin G (IgG) and complement 3 (C3) deposits in the alveolar basement membrane.
- Serum and kidney biopsies were negative for anti-glomerular basement membrane (anti-GBM) antibodies.
- An elevated T helper/T suppressor (T4/T8) cell ratio of 5 was noted in peripheral blood.
Findings:
- The patient received prednisolone and cyclophosphamide, leading to temporary cessation of pulmonary bleeding.
- Recurrent hemoptysis necessitated plasma exchange, which proved successful in controlling the bleeding.
Implications:
- This case highlights a potential autoimmune pulmonary hemorrhage in a pediatric patient.
- The findings suggest a possible role for T-cell dysregulation in the pathogenesis.
- Successful management involved a combination of immunosuppression and plasma exchange.
