A Fatal Case of Multidrug-Resistant Pleural Nocardiosis by Nocardia otitidiscaviarum in an Immunosuppressed Patient: A Case Report and Literature Review
Abstract
Nocardiosis is known as an opportunistic infection in immunocompromised hosts. We present to you a case of pleural nocardiosis in a 38-year-old male patient who was a chronic smoker and presented with a left-sided pleural effusion. He was a known case of thrombocytopenia due to immune thrombocytopenia (ITP) and was on steroid therapy. On admission, he was found to be positive for HIV. Pleural fluid was sent to microbiology, where acid-fast staining with 1% sulfuric acid (H2SO4)showed acid-fast branching filamentous rods and cultures grew Nocardia, which was resistant to ampicillin, ceftriaxone, imipenem, cotrimoxazole, erythromycin, tetracycline, and susceptible to amikacin, linezolid, and levofloxacin. The isolate was identified as Nocardia otitidiscaviarum using 16S rRNA gene sequencing. Culture from the chest wall drain grew Escherichia coli and Stenotrophomonas maltophilia. Subsequently, the patient developed sepsis, and paired blood cultures grew Candida guilliermondii. Unfortunately, the patient could not survive despite aggressive efforts and died after 40 days of admission.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
