History of Present Illness

A 67-year-old woman with history of chronic lymphocytic leukemia (CLL) was referred due to a 6-week history severe cough. Her CLL had recently relapsed and she was begun on ibrutinib (a small molecule drug that binds permanently to Bruton's tyrosine kinase) in addition to acyclovir, sulfamethoxazole/trimethoprim and allopurinol.

Past Medical History, Social History and Family History

Her CLL was initially diagnosed in 2009 and had responded to fludarabine, cyclophosphamide, and rituximab. She had no other chronic medical diseases. She smoked ½ pack per day but quit with the development of her cough. Family history was noncontributory.

Laboratory Evaluation

Her complete blood count revealed her to be mildly anemic with a hemoglobin of 9.0 g/dL, an elevated white count of 33,700 cells/mcL with 88% lymphocytes, and a low platelet count of 60,000 cells/mcL. Her electrolytes were within normal limits and her blood urea nitrogen was 20 mg/dL, creatinine 1.1 mg/dL and uric acid 7.1 mg/dL.

Chest Radiography

A chest x-ray was performed (Figure 1).

2. Ibrutinib is well known to cause a chronic cough
