Accelerated usual interstitial pneumonitis, anti-DNA antibodies and hypocomplementemia.
A healthy 60-year-old patient presented with progressive dyspnoea. Clinical, radiographic and pathological features of interstitial lung disease were found and an open lung biopsy established the diagnosis of usual interstitial pneumonitis (UIP) (idiopathic pulmonary fibrosis). Despite treatment, the patient died 4 months later in respiratory failure. Although the patient had no extra-thoracic involvement at autopsy, his illness was associated with a very high titre of anti-double-stranded DNA antibodies, hypocomplementemia, hypergammaglobulinaemia and lymphoid hyperplasia. These features and a literature review, suggest immune-mediated lung damage in a subset of patients with UIP.
