Chronic cough and cystic lung disease caused by Bordetella bronchiseptica in a patient with AIDS. Issue 4 (16th April 2019) - Sameed, Muhammad
Abstract : A 24-year-old man with a history of HIV and large B cell lymphoma (currently in remission) presented with fever, dry cough and dizziness. His CD4+ count was undetectable, and the HIV viral load was 109 295 cop/mL. Physical examination revealed fever, hypotension and tachycardia with coarse breath sounds in the middle and lower chest zones bilaterally. Chest imaging showed diffuse abnormal micronodular and patchy infiltrates, without focal consolidation. A cavitary lesion was noted measuring 5×2 cm in axial dimensions within the left lower lobe and multiple small cystic lesions in the background. Bronchoalveolar lavage fluid culture grew Bordetella bronchiseptica . The patient was empirically treated with vancomycin and piperacillin–tazobactam for multifocal pneumonia with concerns for sepsis and was started on combined antiretroviral therapy (cART) with abacavir/dolutegravir/lamivudine. Symptoms improved after day 3 of therapy, and the patient was discharged home on 2 weeks of moxifloxacin, in addition to the cART and appropriate chemoprophylaxis.
