Cefpirome (HR 810) is a new cephalosporin with a 2,3-cyclopentenopyridine group in the 3-position side chain. It was compared with other cephem antibiotics in protective and therapeutic effects on various experimental infections, systemic and local, in mice and rats. HR 810 had more potent protective effect than ceftazidime (CAZ), cefoperazone (CPZ), and cefotaxime (CTX) on systemic infections induced by Escherichia coli Ec-31, Staphylococcus aureus SMITH, and Serratia marcescens Sm-6 in mice. Against systemic infection with Pseudomonas aeruginosa HR 810 was as effective as CAZ. Mice with
leukopenia
induced by cyclophosphamide were systemically infected with methicillin-resistant S. aureus (MRSA), methicillin-susceptible S. aureus (MSSA), Enterobacter cloacae, Acinetobacter calcoaceticus, and Enterococcus faecalis. HR 810 was superior to cefuzonam (CZON) and cefmetazole against MRSA and MSSA and was much more active than any other antibiotics tested against E. cloacae and A. calcoaceticus. In the activity against E. faecalis, HR 810 was inferior to ampicillin but superior to CZON. In mice with
pyelonephritis
caused by E. coli Ec-7, the rank order of activities was HR 810 greater than CAZ greater than CTX greater than CPZ. HR 810 was more effective than latamoxef, CAZ, CTX, and CPZ in improving lung infections induced by Streptococcus pneumoniae HL 438 and Klebsiella pneumoniae Kp-51 in mice. HR 810 was superior to CTX and CPZ and comparable to cefazolin in therapeutic effects on intrauterine infections with E. coli Ec-89 and S. aureus SMITH in rats.

Ofloxacin, a new fluoroquinolone, was given to fifty patients (29 females and 21 males) aged 25 to 86 years with urinary tract infection or prostatitis. Urinary tract infections usually chronic and associated with urologic anomalies, included 17 cases of cystitis and 19 cases of
pyelonephritis
. 14 patients had prostatitis. Pathogens recovered from the urine were 26 E. coli, 2 Citrobacter, 4 Proteus mirabilis, 2 Klebsiella, 2 Enterobacter, 3 Serratia, 3 Staphylococcus aureus and 11 Pseudomonas. Minimal inhibitory concentrations of ofloxacin ranged from 0.03 to 0.12 microgram/ml (mean MIC: 0.6 microgram/ml) for 27 nalidixic acid-sensitive strains, and from 0.25 to 4 micrograms/ml (mean MIC: 1 microgram/ml) for 26 nalidixic acid-resistant strains. Ofloxacin was given as single drug therapy in all patients, in a daily dosage of 200 mg b.i.d. in 46 patients and 400 mg b.i.d. in 4 patients, for 7 to 97 days (average 40 days). Follow-up after discontinuation of treatment was 3 to 12 months. Therapeutic results were as follows: 17 cures for the 17 cystitis patients, 17 cures and 2 failures by relapse for the 19 cases of
pyelonephritis
, and 11 cures, 1 failure by persistence of bacteriuria and failure by relapse for the 14 cases of prostatitis. Digestive disorders, i.e. nausea, abdominal pain, constipation, occurred in 6 patients and required withdrawal of the drug in 1; candidiasis of the tongue was recorded in one patient and digestive complaints with neuropsychic disorders in another. Two patients had short-lived, moderate
leukopenia
with granulopenia and one had transient worsening of preexisting renal failure. Hepatic tolerance was good.

Cefuzonam (L-105, CZON), a new parenteral cephalosporin, was evaluated for its efficacy and safety in 22 children with bacterial infections (Table 1). The results obtained are summarized below. MICs of CZON to 26 strains of isolated organisms are shown in Table 2. MICs to all 14 strains of Haemophilus influenzae and 6 strains of Streptococcus pneumoniae were less than 0.05 microgram/ml. The MIC to 2 strains of Staphylococcus aureus was 0.39 microgram/ml and that to another was 0.78 microgram/ml. Two strains of Escherichia coli showed MICs of less than 0.05 and 0.10 microgram/ml, respectively. The MIC to 1 strain of Enterococcus faecalis was 6.25 micrograms/ml. The CZON was administered in 3 or 4 divided doses at a daily dosage ranging from 58.5 to 85.7 mg/kg by 30-minute drip infusion or intravenous injection to 22 patients (9 cases of pneumonia, 9 cases of tonsillitis, 2 cases of bronchitis, 1 case each of suppurative parotitis and acute
pyelonephritis
) and the following clinical results were obtained; excellent: 12 cases; good: 7 cases; fair: 3 cases. The overall efficacy rate was 86% (Table 4). Diarrhea was observed in four patients, and was resolved with or without discontinuation of the medication within a week. Anemia was noted in 2 cases.
Leucopenia
and neutropenia was observed in 1 case. There were a moderate rises in S-GOT and S-GPT activities in 1 patient (Table 4), and they necessitated the cessation of the CZON therapy. The S-GOT and S-GPT activities became normal after the drug treatment was stopped.(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)

Twenty-six children received a single daily intravenous dose of ceftriaxone, 50 mg/kg, for a variety of bacterial infections including abscess (5), cellulitis (5), periorbital cellulitis (5), bacteremia without focus (4), osteomyelitis (2), pneumonia (2),
pyelonephritis
(2) and otitis media (1). Organisms isolated from infectious foci were Staphylococcus aureus (9), Streptococcus pneumoniae (6), Streptococcus pyogenes (3), Escherichia coli (2); and Haemophilus influenzae type b, nontypable H. influenzae, Group B streptococcus, Pasteurella multocida, Haemophilus parainfluenzae and satelliting streptococcus (1 each). Microbiologic cure was achieved in 20 of 22 (91%) infections and clinical cure in 25 of 26 (96%). Fifteen possible adverse reactions occurred in 34 patients evaluable for drug safety; most were mild and self-limited. Neutropenia developed in two patients necessitating discontinuation of ceftriaxone in one, followed by prompt resolution. Seventeen children received ceftriaxone, 75 mg/kg/day, in two divided doses for a similar variety of infections. Bacteriologic and clinical cure rates of 100 and 94%, respectively, were demonstrated.
Leukopenia
developed in one patient and resolved when ceftriaxone was discontinued. Once a day dosing of ceftriaxone in pediatric patients provides greater ease of administration combined with efficacy equal to that achieved with a divided dosage schedule.

Renal scarring is considered to develop in the later stages of chronic
pyelonephritis
. In our experimental model of
pyelonephritis
, bacteria with mannose-sensitive (MS) pili on their surface promoted renal scarring following inoculation into the renal parenchyma. The administration of cyclophosphamide to induce
leukopenia
and of superoxide dismutase to inactivate superoxide released from polymorphonuclear leukocytes (PMN) at the infection site suppressed any renal scarring following the infection. Conversely, the administration of phorbol myristate acetate at an early stage of infection significantly enhanced the renal scarring. These findings suggest that the PMNs which infiltrate the infection site and the superoxide they release play an important role in any renal scarring following infection with MS-piliated bacteria.

We developed a new experimental model of ascending Candida pyelonephritis in female rats with
leukopenia
and vesicoureteral reflux. Rats were treated transperitoneally with cyclophosphamide (200 mg/kg) to induce
leukopenia
3 days before and transurethrally with diluted acetic acid solution to induce vesicoureteral reflux 1 day before inoculation of Candida albicans strain, ATCC 10259 (containing 10(7) cells). Microscopy revealed acute
pyelonephritis
in which Candida cells invaded from the fornix and/or papilla into the medulla within 3 days after inoculation. Between 7 and 28 days after inoculation, chronic
pyelonephritis
reached the cortex. The incidence of
pyelonephritis
increased gradually and was approximately 80% after 7 days. Candida colony counts of bladder urine specimens obtained by direct puncture were significantly greater in rats with
pyelonephritis
extending into the parenchyma than in those with
pyelonephritis
located along the pelvis (p < 0.01). These results suggest that this rat model shows the characteristic feature of ascending
pyelonephritis
due to C. albicans and that the severity of Candida pyelonephritis can be estimated from Candida counts of bladder urine.

A 48-year-old female with severe aplastic anemia was scheduled for transurethral lithotomy because of
pyelonephritis
and urethral stone. Laboratory studies showed anemia (168 x 10(4).mm-3),
leukopenia
(2300.mm-3) and thrombocytopenia (5000.mm-3). Bleeding time exceeded 30 min, but the transfusion of fresh platelet concentrate was not effective for bleeding tendency. Anesthesia was induced with midazolam 0.5 mg and fentanyl 100 micrograms, and maintained with N2O-O2-sevoflurane through a mask. The operation, which lasted for 40 min, was uneventful without marked hemodynamic changes, bucking or massive bleeding. Although 100 units of fresh platelet and 13 units of leucocyte poor red cells were infused during hospitalization, macrohematuria continued for about 3 weeks after this operation.

A 37-year-old woman with a personal history of appendicectomy, cholecystectomy, left oophorectomy secondary to an ovarian cyst complication, nephritic colic with repeated episodes of
pyelonephritis
, alcoholic hepatopathy, Raynaud's phenomenon and bilateral exophthalmos showed an increase in volume in the root of the upper limbs and in the base of the neck over a period of 4 years, painful to the touch and of a soft consistency. She presented with a pseudo-athletic appearance (Fig. 1) produced by an increase in the volume at the root of the upper limbs, upper back and the back of the neck (Fig. 2). The lesions produced a pulling sensation and were associated with paresthesia, hyperesthesia, and a moderate loss of strength in both arms. A biopsy taken from the upper third of the right arm showed a diffuse proliferation of the subcutaneous adipose tissue, which appeared normal, and extended between the collagen fibers, reaching in some cases into the most superficial zones of the reticular dermis (Fig. 3). Laboratory evaluation revealed a chronic anemia,
leukopenia
with moderate lymphopenia, increased erythrocyte sedimentation rate, elevation of enzymes of hepatic function, decrease in total proteins, and increase in ferritin, all in the context of hepatopathy. Antinuclear antibodies and the hormonal profile were normal. Abdominal and gynecologic echography revealed a right ovarian cyst of no clinical relevance. Cranial nuclear magnetic resonance (NMR) revealed an increase in the periorbital fat responsible for bilateral exophthalmos.
