First case of New Delhi metallo β-lactamase-1 (NDM-1)-producing Burkholderia cepacia complex in Iran
Abstract
The Burkholderia cepacia complex (Bcc) is a gram-negative bacillus, which is intrinsically resistant to several used antibiotics, and is now recognized as a group of opportunistic pathogens in Cystic Fibrosis patients. Here, for the first time, we report the case of a patient with New Delhi metallo β-lactamase (NDM)-positive Bcc lower respiratory tract infection in Iran. The patient was a 57-year-old male admitted to our hospital due to breathlessness, with a history of pulmonary thromboembolism and hypertension. On day 14, the patient underwent bronchoscopy and a bronchoalveolar lavage (BAL) specimen was taken. BAL culture grew Bcc. The drug resistance analysis showed positive NDM resistance, with susceptibility to only quinolones, therefore, levofloxacin was prescribed to the patient. He was discharged from the hospital on the 20th day, 4 days after the initiation of levofloxacin therapy, and died at home on the fifth day after discharge. This is the first report of a lung infection caused by an extensively drug-resistant NDM-positive Bcc strain in Iran.
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.
