Whipple disease revealed by lung involvement: a case report and literature review.

We report the case of a man with a history of intermittent fever and arthritis who presented with a dry cough and associated lung involvement, who was eventually given the diagnosis of Whipple disease. The pulmonary symptoms preceded the development of GI manifestations. Five years later, periodic acid-Schiff (PAS)-positive macrophages were identified in duodenal biopsy specimens and polymerase chain reaction for Tropheryma whipplei was positive in the duodenum, stools, saliva, and cerebrospinal fluid.

Churg-Strauss syndrome associated with omalizumab.

Reports have suggested that the leukotriene receptor antagonists may cause Churg-Strauss syndrome following the tapering of oral corticosteroids or even in patients not treated with corticosteroids. We report a patient not treated with long-term corticosteroids and who developed Churg-Strauss syndrome with myocarditis and central nervous system involvement following the initiation of omalizumab. Given the possible role of omalizumab in the development of this vasculitis in our patient, we recommend careful monitoring of the appearance of Churg-Strauss symptoms and rising eosinophil count in patients treated with omalizumab.
