Ceftriaxone, a third-generation cephalosporin with a long half-life, was administered intramuscularly to 30 adult women suffering from acute pyelonephritis. Standard bacteriologic methods were used to identify the pathogens and their susceptibilities before treatment and at intervals during and after treatment. Overall cure was achieved in 25 (85%) of the patients 6 weeks after completion of therapy. The results demonstrate that ceftriaxone is an effective drug when given once a day intramuscularly to out-patients with acute pyelonephritis.

Efficiency of ceftriaxone (Rocephin Hoffman Laroche) was assessed in 16 children aged between 3 and 14 years and in 4 adults aged between 17 and 70 years with severe infections of the urinary and respiratory tracts caused by E. coli. S. pneumoniae, P. aeruginosa, P. mirabilis or enterococci. Pyelonephritis as a sole pathology was diagnosed in 10 patients whereas in further 8 patients it complicated other diseases (nephrotic syndrome, hepatitis, cholangitis, leukemia). Pneumonia complicated nephritis leukemia or lymphoma in 8 children. Peritonitis was diagnosed in 1 adult patient. Ceftriaxone was given in a single daily dose of 50 mg/kg to all children and 2.0 g to adult patients for 7-10 days. No adverse reactions were noted. Clinical improvement was achieved in all treated patients. Cultures became negative in 17 cases after the treatment. Significant bacteremia caused by P. aeruginosa persisted in 2 patients and by E. coli in 1 patient. No toxic effects on liver, renal, pancreatic and bone marrow functioning were seen. Ceftriaxone may be safely and efficiently used for the treatment of the urinary and respiratory infections.

Ceftriaxone (CTRX) was evaluated for clinical efficacy on uncomplicated and complicated pyelonephritis by administering 2 g once daily for 5 days to 16 female patients between 20 and 65 years old (average: 39.7 years); i.e., 3 with uncomplicated pyelonephritis and 13 with complicated pyelonephritis. The pathogens in all 3 cases of uncomplicated pyelonephritis were E. coli. All of them disappeared after the treatment. Twenty-two strains of 10 strains of bacteria were isolated from the 13 cases of complicated pyelonephritis. Twenty of the 22 (91%) strains disappeared. The clinical efficacy was evaluated according to the Criteria for Evaluation of Clinical Efficacy of Antimicrobial Agents on UTI Japan in 15 cases except for 1 case of the complicated type where the CTRX administration was discontinued after the initial dose due to an adverse event. The efficacy rate was 100% in the 3 uncomplicated cases; 'excellent' in 1 case and 'good' in 2, and 92% in 12 of the complicated cases; 'excellent' in 9, 'good' in 2 and 'poor' in 1 (infection was with multiple pathogens including P. aeruginosa). No abnormal values were observed in any cases except for a slight increase in glutamic-pyruvic transaminase and alkaline phosphatase in one case and skin rash in another case which appeared following the initial dose and required the immediate withdrawal of the drug. CTRX is characterized by a long half-life and shows a strong antibacterial activity against GNRs, especially E. coli. The efficacy rate was high particularly following the initial dose in the acute stage of pyelonephritis.(ABSTRACT TRUNCATED AT 250 WORDS)

Ceftriaxone (CTRX) was studied for its efficacy and safety in 8 cases of infection during the perinatal period; 6 before, and 2 after delivery. The results obtained are recognized as follows: 1. CTRX was administered by intravenous drip infusion at a daily dose between 2 and 4 g for 2 to 10 days (a total dose: 4 to 20 g) each of 8 cases of infections during the perinatal period; 3 of amniotic fluid infection and 1 each of intrauterine infection, puerperal fever, puerperal wound infection, appendicitis and pyelonephritis. CTRX was evaluated to be very effective in 3, effective in 3 and ineffective in 2, with an efficacy rate of 75% (6/8). 2. Two strains of Enterococcus faecalis and 1 each of Pseudomonas cepacia and Streptococcus intermedius were isolated. All of them were eradicated by the CTRX treatment bacteriologically. 3. No adverse reactions were observed subjectively or objectively. A slight transient elevation of GOT, GPT and Al-P was observed in 1 case. No abnormal sign was observed in neonates.

Ceftriaxone treatment (50 to 80 mg/kg once daily) was given to 201 children between 1 month and 18 years of age. There were 201 serious bacterial infections, including epiglottitis, pneumonia, cellulitis, osteomyelitis, septic arthritis, pyelonephritis, sepsis, and meningitis. The common pathogens responsible for pediatric infections isolated from these patients included Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, and Escherichia coli. The overall clinic cure rate was 94%. Ten patients were clinically improved but not cured. There were two clinical failures. Bacteriologic failure occurred in six patients. The overall bacteriologic cure rate was 97%. Twenty patients (10%) experienced adverse effects; none required discontinuation of therapy. The efficacy, safety, spectrum, and convenience of ceftriaxone monotherapy make this antimicrobial agent a candidate for the treatment of choice of selected serious pediatric infections.

An acute exudative Escherichia coli pyelonephritis rat model was used to study the influence of progressive pyelonephritis on the efficacy of antibiotic treatment. In this model, transient ureteral obstruction after E. coli bladder inoculation induces early bacterial multiplication in the kidney parenchyma, and the bacterial counts peak by 48 h. The inflammatory response (assessed by the increase in kidney weight) is somewhat delayed, starting 36 h after inoculation and peaking by 72 h. Groups of rats received 4 doses over 48 h of saline, ceftriaxone (100 mg/kg), or ceftriaxone (100 mg/kg) plus gentamicin (4 mg/kg). These treatments were initiated 24, 36, 48, or 72 h after bladder inoculation. Antibiotic treatment started at 24 h was significantly more effective in reducing bacterial counts in the kidney parenchyma than at any later therapy onset. Only when started 24 h after inoculation was the synergistic combination of ceftriaxone plus gentamicin more effective in reducing bacterial counts than ceftriaxone alone. Ceftriaxone and ceftriaxone plus gentamicin regimens started at 24 h reduced significantly (by 42 and 55%, respectively) the incidence of acute exudative pyelonephritis when compared with the incidence in saline-treated controls. Early therapy onset (24 h) strikingly reduced the development of the inflammatory response. This reduction was less marked when antibiotic therapy was started at 36 h and no longer apparent when therapy onset was delayed up to 48 or 72 h. In conclusion, the efficacy of antibiotics in eradicating bacteria from the kidney parenchyma and in preventing acute exudative pyelonephritis was markedly hampered by the development of pyelonephritis.

Thirty patients (17 male, 13 female; age 17 to 84 years; normal renal function in 23 cases) with severe bacterial infections were treated with ceftriaxone. The infections was septicemia in 20 cases, a septicemia-like condition in 2 and a focal infection in 8 (2 abscesses of the lung, 2 pyelonephritis, 1 abscess of the liver, 1 subphrenic abscess, 1 meningitis developed from an abscess of the brain and 1 acute intestinal infection). 25 infections were bacteriologically documented, with recovery of the following pathogens: 20 Gram negative rods (including 10 E. coli) that were all susceptible to ceftriaxone (MIC = 0.02 to 0.5 mg/l) except 2 (1 Pseudomonas and 1 E. cloacae), 5 susceptible Gram positive cocci (3 Pneumococcus, 1 Streptococcus and 1 Staphylococcus epidermidis) and 3 susceptible anaerobes (2 B. fragilis and 1 B. melaninogenicus). Ceftriaxone was given alone in 15 cases and in association with another antibiotic in 15 cases (aminoglycoside in 10 cases, nitroimidazole in 4 and fosfomycin in 1). The dose of ceftriaxone was 1 to 2 g per day in 28 cases, 3 g per day in 1 case (meningitis with abscess of the brain) and 1 g every other day in 1 case (chronic renal failure under hemodialysis). Duration of treatment ranged from 10 to 62 days (average 17 days). The usual routes of administration were IV and IM; the SC route was used on 4 occasions. Pharmacokinetic studies of serum levels were carried out in several patients including two who had ceftriaxone subcutaneously; results were consistent with those previously reported in the literature.(ABSTRACT TRUNCATED AT 250 WORDS)

Ceftriaxone has a very long serum half-life and enhanced in vitro activity against common pediatric pathogens. Therefore we evaluated the efficacy and safety of once daily ceftriaxone therapy in 57 children with serious infections including: meningitis (26 patients); ventriculitis (3); pyelonephritis (7); osteomyelitis (6); abscess (4); septic arthritis (3); sepsis (2); and miscellaneous infections (6). The most common isolates were Haemophilus influenzae (23), Escherichia coli (9) and Staphylococcus aureus (8). Ceftriaxone was given intravenously or intramuscularly in a dose of 50 mg/kg for non-central nervous system (CNS) infections. Patients with CNS infections received an initial dose of 100 mg/kg followed by 80 mg/kg 12 hours later and once daily thereafter. In a limited number of patients no major differences in serum ceftriaxone concentrations were found after intravenous or intramuscular injection. Of 57 patients with pathogens isolated 55 were completely cured; in one patient with Klebsiella pneumoniae ventriculitis, intraventricular gentamicin was briefly added to the regimen. Another patient with an anaerobic liver abscess recovered after metronidazole was administered. In three patients a delayed response to ceftriaxone was noted. One patient with previous recurrent infections had a second episode of H. influenzae meningitis 22 days after cessation of therapy. Clinical side effects were noted in 10 of 71 patients (including 14 treated patients who had negative cultures). Seven patients had diarrhea, one each had fever or rash and one had fever, rash and arthralgia. Laboratory side effects in 16 of 71 patients included eosinophilia (7), thrombocytosis (7), elevated liver enzymes (4) and leukopenia and neutropenia (2).(ABSTRACT TRUNCATED AT 250 WORDS)

Cefonicid (Monocid) and ceftriaxone (Rocephin) are long half-life cephalosporins that may be used for serious infections in the outpatient setting. They may be used as an extension of initial hospital treatment, or therapy can be initiated and completed in many cases with the patient remaining at home. Sufficient clinical experience exists with both ceftriaxone and cefonicid to recommend these agents for selected patients having pyelonephritis, osteomyelitis, or soft tissue infections. Cefonicid, perhaps in combination with erythromycin, will provide excellent coverage for complicated community-acquired pneumonias. Ceftriaxone is effective as single-dose therapy for even complicated gonococcal infections. The use of long half-life cephalosporins in ambulatory practice may result in substantial cost savings for certain patients.

Ceftriaxone (Ro 13-9904, CTRX), a new parenteral cephalosporin, was used for pediatric infections and the following results were obtained. CTRX was administered twice daily by intravenous injection with about 20 mg/kg in 6 cases consisting of 2 cases with purulent lymphadenitis of the neck, 2 with urinary tract infection, 1 with sepsis and pyelonephritis and 1 with sepsis and purulent lymphadenitis of the neck. The result was excellent in 4 and good in 2. One case with H. influenzae meningitis, receiving 50 mg/kg CTRX by intravenous injection twice daily, showed an excellent response without having any sequela. Among those mentioned above, diarrhea in 2 cases and elevated GOT and GPT in 2 were observed, all of which were transitory and not serious. The blood level of CTRX at 1/2, 1, 2, 4, 6 and 8 hours after intravenous injection with 20 mg/kg to a girl of 8 years and 8 months of age with urinary tract infection was 114, 86, 70, 42, 29 and 21.8 micrograms/ml, respectively. The half-life time was 3.5 hours while the urinary recovery rate up to 6 hours was 58.0%. The concentration in the cerebrospinal fluid of 1 case with H. influenzae meningitis ranged from 2.1 to 8.2 micrograms/ml at 3 hours after administration and from 1.15 to 2.65 micrograms/ml after about 12 hours (prior to the next administration). The above-mentioned results suggest that CTRX is a new antibiotic useful for pediatric infections caused with susceptible bacteria and is effective by intravenous injection with 10 mg/kg twice daily for moderate infections and with 20 mg/kg twice daily for severe ones, except for meningitis. As for purulent meningitis, the administration dosage and frequency will have to be further examined based on the intravenous injection with 50 mg/kg twice daily.
