A Case Report of Urinary Tract Infection and Fungemia Due to Pichia ohmeri Complicated with Pulmonary Thromboembolism.

Pichia ohmeri (P. ohmeri) is a rare human pathogen known to cause severe conditions such as sepsis, fungemia, endocarditis, and peritonitis, often resulting in high mortality rates. This report presents a case of a febrile 66-year-old male with a urinary tract infection and fungemia caused by P. ohmeri. The patient had additional complications of pulmonary thromboembolism (PTE) and deep venous thrombosis (DVT) in the left lower extremity. Notably, the pathogen was isolated in both urine and blood cultures, an uncommon finding in immunocompetent patients. Treatment with fluconazole was initiated based on the antifungal susceptibility testing (AFST) results. Following treatment, the patient experienced a gradual resolution of fever and urinary tract infection symptoms. Concurrently, anticoagulant therapy was administered for the management of PTE and DVT. The patient was eventually discharged in a stable condition.
