Cyclophosphamide is widely used in neoplastic and inflammatory diseases. Although several adverse events have been described with its use, acute and subacute interstitial pneumonitis leading to pulmonary fibrosis is rare and potentially fatal. This case report describes a 64-year-old man who, after the fifth chemotherapy cycle, developed a severe ARDS leading to pulmonary fibrosis in just 30 days.

Current international consensus guidelines identify a number of indicators for the establishment of home mechanical ventilation (HMV) for patients with neuromuscular diseases but do not address the possible clinical differences between each of the underlying disorders. This study assessed the differences in the physiological parameters of patients with neuromuscular disease commenced on HMV for the treatment of symptomatic chronic hypercapnic respiratory failure. ⋯ Blood gases and lung function parameters vary substantially between patients with differing underlying neuromuscular disorders when commenced on HMV for the treatment of symptomatic chronic hypercapnic respiratory failure. In contrast, PImax is equally reduced in all patients and more severely reduced compared with consensus guidelines. The specific underlying neuromuscular disease has a major impact on outcome. Specific selection criteria are needed for the use of HMV in the different diseases that comprise neuromuscular disorders.

A variety of markers, such as serum angiotensin-converting enzyme (sACE) and CXR have been used to evaluate the disease activity and progression of sarcoidosis. There are patients who have developed cardiac involvement several years after the initial diagnosis despite stable or decreased disease activity. This study clarified the clinical characteristics of those patients. ⋯ Middle-aged women with multiple organ involvement of sarcoidosis are at risk of developing cardiac sarcoidosis.
