Eighty-three episodes of Gram-positive infection in 82 patients were treated with teicoplanin in an open study. Infectious episodes included endocarditis (6 cases), bacteraemia (7), osteomyelitis (8), pseudomembranous colitis (13), cellulitis (11), urinary tract infection (5), pneumonia (1), wound and post-surgical infections (9) and erysipelas (23). Four patients affected by an overwhelming Gram-positive infection as well as eight cases of Gram-positive-Gram-negative mixed infections received teicoplanin in combination with other antibiotics. The average duration of treatment was 16 days (range 5-70). In pseudomembranous colitis teicoplanin was given by mouth for ten days. Staphylococcus aureus (11 methicillin-sensitive and 13 methicillin-resistant strains) and Clostridium difficile (13 isolates) were the most frequent pathogens. Overall 89% (74/83) of the infections were cured, 3.6% (3/83) improved and 3.6% (3/83) failed. Relapse and superinfection were observed in 2.4% (2/83) and 1.2% (1/83) episodes respectively. All pseudomembranous colitis cases were clinically cured and C. difficile was eradicated in all but one patient. The MIC range, MIC50 and MIC90 (mg/l) of teicoplanin for C. difficile were less than 0.125-0.250, less than 0.125 and 0.250 respectively. Pharmacokinetic studies in patients given a single iv daily maintenance dose of 400 mg showed that the steady-state trough teicoplanin concentrations in serum were reached on day 8. Assays of skin-subcutaneous tissue biopsies showed that teicoplanin penetrated well into these structures. Side effects were observed in six of the 82 treated patients (7.3%) and teicoplanin had to be discontinued in four cases. The results of the study show that teicoplanin is a safe and useful new agent for the treatment of infections caused by Gram-positive organisms, including methicillin-resistant staphylococci and C. difficile.

Aztreonam was used in the initial treatment of infection of the urinary tract (23 cases), respiratory tract (17 cases), skin and soft tissue (12 cases), abdominal cavity (three cases), endocarditis (two cases), septicemia (eight cases), and osteomyelitis (two cases). In 26 of 60 evaluable infectious episodes, aztreonam was used alone. Clinical cure was observed in 35 of 60, improvement in 24 of 60, and failure in one of 60 cases. Ten patients developed subsequent superinfection. Aztreonam was well tolerated, although one case of exfoliative dermatitis and one of pseudomembranous colitis occurred. However, these cases were complicated by proximal administration of other antibiotics.

Bacteria recently recognized as nosocomial pathogens generally fall into three categories: those that grow slowly, those that are fastidious in their nutritional or atmospheric requirements and those that resemble commensals. Each characteristic has contributed to the delay in perceiving their importance. Mycobacterium chelonei and Myco. fortuitum--which grow slowly, although characterized as "rapid-growing" mycobacteria--cause sternal osteomyelitis, pericarditis and endocarditis after cardiac surgery as well as other wound infections after many types of surgery. Myco. chelonei-like organisms have been found to cause "sterile" peritonitis in patients receiving long-term peritoneal dialysis. Legionella pneumophila and L. micdadei are fastidious bacteria that were more difficult to detect because they stain poorly with the Gram method. They cause pneumonia and lung abscess, especially in immunocompromised people. Clostridium difficile is an anaerobe that causes toxin-mediated pseudomembranous colitis in persons given antibiotics that inhibit competing gut bacteria. Chylamydia trachomatis, an intracellular organism that has not been grown in vitro, causes pneumonia and conjunctivitis in young infants who acquire the organism from their mothers at birth. Group JK bacteria cause septicemia in patients whose immune responses have been suppressed and must be distinguished from "diphtheroid" contaminants in blood cultures. Clinicians, microbiologists and epidemiologists must be alert to the characteristics of these organisms that make them easily overlooked and should also anticipate the existence of other bacteria not yet identified.

Patients with serious staphylococcal infections, e.g. endocarditis and osteomyelitis, need prompt and prolonged parenteral antibiotic treatment to ensure eradication of the causative pathogen. The major cost in the treatment of these infections is the long period of hospitalisation required for the administration of intravenous antibiotics. To shorten the hospitalisation period, outpatient treatment can be given to some patients. In this study, patients with acute exacerbations of chronic osteomyelitis (n = 44) or endocarditis (n = 10) were treated with intravenous teicoplanin. The pathogens were Staphylococcus aureus (n = 41, 13 of which were methicillin resistant) and coagulase-negative staphylococci (n = 13, one of which was methicillin resistant). After a mean loading dose of 15 mg/kg for 3 to 10 days, patients received teicoplanin 3 times a week at a dose (mean 15 mg/kg) individualised to achieve serum trough concentrations of approximately 10 mg/L for osteomyelitis and 20 mg/L for endocarditis. Treatment duration ranged from 28 to 150 (mean 62) days for patients with osteomyelitis and from 28 to 88 (mean 49) days for patients with endocarditis. 37 (84%) patients with osteomyelitis and 8 (80%) patients with endocarditis were treated successfully. Adverse events were observed in 9 patients and included rash (n = 3), thrombocytopenia (n = 3), and drug fever, pseudomembranous colitis, nausea, leucopenia and transient hearing impairment (one patient each). In conclusion, this study demonstrates that teicoplanin can be administered successfully in an outpatient setting according to a 3-times weekly schedule for the treatment of patients with staphylococcal osteomyelitis and endocarditis.

Clindamycin is an antimicrobial agent that dentists use in the UK for infective endocarditis prophylaxis but rarely for other clinical situations that require antimicrobial intervention. This has been largely due to its association with acute pseudomembranous colitis. Up to date information on the efficacy and safety of this antimicrobial agent should be known before prescription.
