In an open, non-comparative study 40 patients with severe, often life-threatening infections, were treated with Timentin 5.2 g (5 g ticarcillin plus 200 mg potassium clavulanate) by iv infusion every 6 or 8 h. They were suffering from septicaemia (9), obstructed UTI (8), non-obstructed urinary tract infection (10), respiratory tract infection (6), infected burns (4) or malignant otitis externa (3). Many patients had important aggravating factors such as renal transplantation, peritoneal or haemodialysis, leukaemia, extensive burns, renal stones, tracheostomy and diabetes. Pathogens included Pseudomonas aeruginosa (21), Escherichia coli (7), and other Enterobacteriaceae (6). Twenty-four pathogens (13 P. aeruginosa) were ticarcillin-resistant. Thirty-six patients were clinically cured including all cases of malignant otitis externa, infected burns and non-obstructed urinary tract infection. Three patients improved and one patient with obstructed urinary tract infection failed. In 32 patients the pathogen was eradicated, in one patient it persisted and in seven it reappeared. In particular, 11 of 13 patients with infections due to ticarcillin-resistant P. aeruginosa were cured and two improved. There was, however, bacteriological relapse in five. There were no side-effects or evidence of toxicity in any of the patients. In an in-vitro study a synergistic effect between ticarcillin and clavulanate was noted against Enterobacteriaceae but only a slight synergistic effect against P. aeruginosa. Studies in patients with normal liver and kidney function showed pharmacokinetic compatibility of the two agents. Timentin can be recommended for the initial treatment of serious infections.

Timentin (5.2 g tds) and tobramycin (40 mg tds) were administered to 51 patients (22 male, 29 female, age range 17-72, mean age 40.4) with acute leukaemia, chronic myeloid leukaemia in blastic crisis, severe aplastic anaemia and acute agranulocytopenia. All patients had neutropenia (PMN less than 1000/mm3) and fever (greater than 38 degrees C). Febrile episodes consisted of 22 proved septicaemias due to Gram-positive organisms (Staphylococcus aureus, S. epidermidis, enterococcus) in 11 cases and to Gram-negative organisms (Escherichia coli, Pseudomonas aeruginosa, Alkaligenes faecalis, Serratia marcescens, Klebsiella pneumoniae) in 10 cases. One patient had a polymicrobial infection (P. aeruginosa, S. aureus, non-haemolytic streptococcus). Twenty-nine infections were diagnosed only clinically. The mean duration of treatment was 11.1 days (range 4-20 days). Eighty-seven per cent of evaluable febrile episodes improved. Among 11 infections due to Gram-positive cocci, eight (72%) resolved, and in nine (90%) of ten cases due to Gram-negative bacilli success was obtained. The polymicrobial infection also resolved. In only four patients were mild side effects seen, e.g. exanthema, pruritus, phlebitis: renal toxicity was not observed. These data suggest that the combination of Timentin and tobramycin is an effective and safe empirical antibiotic regimen in febrile neutropenic patients.
