Recurrent haemoptysis following sildenafil administration.

Sildenafil is widely used in the treatment of male erectile disorder and is generally well-tolerated. Its adverse effects are reported to be mild and include flushing, headache, dyspepsia and visual disturbances. We document a case of recurrent haemoptysis observed soon after self administration of sildenafil in a 38-year-old male with no other causative factors. The episodes of haemoptysis stopped following stoppage of sildenafil.

Diffuse Alveolar Hemorrhage Associated with Antineutrophil Cytoplasmic Antibody levels in a Pregnant Woman Taking Propylthiouracil

Propylthiouracil (PTU) is known to be a potential cause of antineutrophil cytoplasmic antibody (ANCA) positive small vessel vasculitis, resulting in glomerulonephritis and diffuse alveolar hemorrhage (DAH). Herein, we describe a 25-year-old pregnant woman who developed a perinulcear ANCA (p-ANCA) and myeloperoxidase ANCA (MPO-ANCA) positive DAH during PTU therapy. The patient improved after corticosteroid therapy and discontinuation of the PTU. Methimazole was prescribed in spite of the risk of recurrence of DAH because of the pregnancy. The patient is currently free from pulmonary problems. Our case shows that the alternative agent, methimazole, can be used to treat hyperthyroidism in a pregnant patient with PTU associated DAH.
