Background:
Apart from leukocytosis, few laboratory markers suggestive of Clostridium difficile infections have been described.
Methods:
We retrospectively analyzed the association between thrombocytosis, leukocytosis and C. difficile infections at the Atlanta Veterans Affairs Medical Center.
Results:
Of 162 patients with C. difficile infection, 36 (22%) had thrombocytosis, and 97 (60%) had leukocytosis. C difficile toxin A ELISA was performed in 46/695 (6.6%) patients with thrombocytosis and was positive in 18 (39.1%). Leukocytosis was present in 16/18 (89%) of patients with positive C. difficile toxin A ELISA and thrombocytosis, but also in 21/28 (75%) of patients with negative C. difficile toxin A ELISA and thrombocytosis. Among patients with marked leukocytosis, C. difficile toxin A was more frequently detected in those with concomitant thrombocytosis (P = 0.07).
Conclusions:
The presence of thrombocytosis may be helpful to improve the pretest probability for C difficile infections.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
Inflammatory Bowel Disease III: Crohn's Disease
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
