Nitrofurantoin-induced pulmonary fibrosis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Nitrofurantoin is a commonly used drug in the treatment and prevention of urinary tract infections. Many adverse effects of nitrofurantoin have been documented, including aplastic anemia, polyneuritis, and liver and pulmonary toxicity.</p> <p>Case presentation</p> <p>We describe the clinical history and the autopsy findings in a 51-year-old woman with lung fibrosis of unknown etiology. She had a history of recurrent urinary tract infections, treated with nitrofurantoin for many years. She was referred to our hospital for screening for lung transplantation because of severe pulmonary restriction and dyspnea. Unfortunately, she died as a result of progressive respiratory insufficiency. At autopsy bilateral patchy, sharply circumscribed fibrotic areas in the upper and lower lobes of the lungs were seen with honeycombing. Microscopically, end-stage interstitial fibrosis with diffuse alveolar damage was observed. Due to the atypical distribution of the fibrosis involving both the lower and upper lobes of the lung, the microscopic pattern of the fibrosis and the history of long-term nitrofurantoin use, we concluded that this drug induced the lung fibrosis. The recurrent urinary tract infections were probably caused by a diverticulum of the urinary bladder, which was discovered at autopsy.</p> <p>Conclusion</p> <p>This case shows that the use of nitrofurantoin may cause severe pulmonary disease. Patients with long-term use of nitrofurantoin should be monitored regularly for adverse pulmonary effects.</p

A rare form of obstructive pulmonary disease Background

Lymphangioleiomyomatosis (LAM) is characterised by progressive dyspnoea, spontaneous pneumothorax and cystic pulmonary destruction. The disease may show similarities with emphysema clinically, radiologically and on lung function tests. Case description A 44-year-old woman was referred for lung transplantation because of a 6-year history of dyspnoea and severe obstructive pulmonary function disorder with decreased diffusion capacity. Both her relatively young age and the fact that she had never smoked made us doubt the diagnosis 'COPD'. The pulmonary cysts seen on high-resolution CT (HRCT) suggested LAM. This was confirmed when we revised a pulmonary biopsy that had previously been performed. Conclusion CT investigation should be carried out in patients with severe obstructive pulmonary disease without a risk profile appropriate for COPD. Diffuse, homogenous cysts on CT scan can indicate LAM, particularly in women. Conflict of interest and financial support: none declared.</p

Lung Transplantation in Gaucher Disease: A Learning Lesson in Trying to Avoid Both Scylla and Charybdis

Gaucher disease (GD), a lysosomal storage disorder, may result in end-stage lung disease. We report successful bilateral lung transplantation in a 49-year-old woman with GD complicated by severe pulmonary hypertension and fibrotic changes in the lungs. Before receiving the lung transplant, the patient was undergoing both enzyme replacement therapy (imiglucerase) and triple pulmonary hypertension treatment (epoprostenol, bosentan, and sildenafil). She had a history of splenectomy, severe bone disease, and renal involvement, all of which were related to GD and considered as relative contraindications for a lung transplantation. In the literature, lung transplantation has been suggested for severe pulmonary involvement in GD but has been reported only once in a child. To our knowledge, until now, no successful procedure has been reported in adults, and no reports deal with the severe potential posttransplantation complications specifically related to G
