Trimethoprim-sulfamethoxazole prophylaxis and antibiotic nonsusceptibility in invasive pneumococcal disease.

ABSTRACT: Among 5,043 invasive pneumococcal disease (IPD) isolates identified through South African national surveillance from 2003 to 2007, we estimated the effect of trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis on antimicrobial resistance. Patients on TMP-SMX prophylaxis were more likely to have a pneumococcal isolate nonsusceptible to TMP-SMX, penicillin, and rifampin. TMP-SMX nonsusceptibility was associated with nonsusceptibility to penicillin, erythromycin, and rifampin and multidrug resistance. This study informs empirical treatment of suspected IPD in patients with a history of TMP-SMX use.

Project description:BackgroundTrimethoprim-sulfamethoxazole (TMP-SMX) is a commonly used antibiotic. While cutaneous adverse drug reactions associated with TMP-SMX are commonly recognized, lung toxicity induced by TMP-SMX is an unusual condition, with scattered reports of hypersensitivity pneumonitis, acute fibrinous organizing pneumonia, interstitial lung disease and acute respiratory distress syndrome. Reports of TMP-SMX-associated drug-induced lung injury (DLI) are rare in the pediatric population and its pathogenesis is not well understood. Diagnosis of DLI remains a challenge, given the wide range of clinical presentations that overlap with other conditions and the lack of diagnostic tests. In this report, we describe a case of TMP-SMX-induced lung injury in an eight-year-old child.Case descriptionAn eight-year-old girl presented in respiratory failure with acute symptoms of shortness of breath, fever, maculopapular rash and vomiting. This was associated with pneumonitis, pneumothorax, pneumomediastinum and subcutaneous emphysema on imaging. She had been on 25 days of TMP-SMX for treatment of Group D Salmonella bacteremia and osteomyelitis that was diagnosed prior to this current presentation. TMP-SMX was discontinued on admission due to concerns of possible drug reaction. Extensive infective, autoimmune and immunologic workup did not reveal the cause of the respiratory failure. Considering the absence of an alternative explanation for her clinical presentation and similarities in clinical courses to other reported cases, she was eventually diagnosed with TMP-SMX-associated DLI. She received a course of corticosteroids with subsequent clinical improvement and was weaned off home oxygen therapy a few months after her discharge from the hospital.ConclusionsDiagnosis of DLI can be challenging. The early identification of DLI and discontinuation of culprit drug is essential in its management. Further understanding of the underlying pathophysiology and risk factors for TMP-SMX-associated DLI is required.
