Clarithromycin Subject 4003/3212/003with ERSP Isolates, PPb
PresentationPresentation:: • 51 year old female, Fine Score II, no relevant risk factors for pneumonia• Chest X-ray: Right median lobe pneumonia and right inferior lobe• Blood cultures:
− S. pneumoniae: susceptible to TEL (MIC = 0.03 mcg/mL),susceptible to Pen G (MIC = 0.03 mcg/mL),resistant to Ery A (MIC = 512 mcg/mL –
genotype ermA / ermB)resistant to CLA (MIC = 64 mcg/mL)
• Sputum cultures: − S. pneumoniae: susceptible to TEL (MIC = 0.25 mcg/mL),
susceptible to Pen G (MIC = 0.03 mcg/mL),resistant to Ery A (MIC = 256 mcg/mL) resistant to CLA (MIC = 256 mcg/mL)
− M. catarrhalis: susceptible to TEL (MIC = 0.12 mcg/mL)
Clinical course:Clinical course:• Day 6: pneumonia worsened with development of septic arthritis. S. pneumoniae
isolated from the pus of septic arthritis. Chest X-ray unchanged. S. pneumoniae was re-isolated from sputum resistant to CLA (MIC=6 μg/mL). Subject hospitalized, discontinued from study medication.
• Patient was switched to IV antibiotics and received gentamicin ceftazidime, metronidazole, penicillin G, cefuroxime with subsequent clinical cure.

Telithromycin Subject 3000/605/1091PresentationPresentation:: • 78 year old female, Fine score III• Chest X-ray: consolidation• Blood cultures:
− S. pneumoniae: susceptible to TEL (MIC = 0.03 mcg/mL),susceptible to Pen G (MIC = 2 mcg/mL),resistant to Ery A (MIC = 32 mcg/mL) –
genotype ermB− Respiratory cultures:
H. influenzae: susceptible to TEL (MIC = 1 mcg/mL)M. catarrhalis: TEL MIC not performed, susceptible by disk
Clinical course:Clinical course:• Initial improvement and sterilization of blood culture at day 12 of therapy,
subject had a recurrence of dyspnea and fever associated with a secondary UTI (S. aureus), treated with intravenous antibiotics
• Clinical status at TOC was improved, blood culture negative for S. pneumoniae (presumed persistent because of the IV antibiotic)

Study 3014: Usual Care • Large experience of co-morbidities (e.g. elderly, elderly female,
CHF, CAD) known to increase TdP risk without any clinical signal (death, arrhythmic death, syncope).
• Large experience of co-therapies (e.g. CYP P450 inhibitors, diuretics, drugs prolonging QTc, digitalis, antiarrhythmics, ) known to increase TdP risk without any clinical signal (death, arrhythmic death, syncope).
• Absence of mortality, arrhythmic death or syncope signals in real-use trial vs. AMC
• Time-course of arrhythmic deaths mitigates against any causal relationship (occurred more than 7 days after telithromycin therapy completed).
