Cephazolin sodium was shown to be as effective as ampicillin in the treatment of respiratory and urinary system infections in patients who were infected with susceptible organisms and had a much less troublesome side reaction rate of hypersensitivity type. In addition, it was found that predictable blood levels of cephazolin could be obtained in patients with renal failure when dosage was regulated according to a nomogram calculated from the patient's serum half-life based on clearance of creatinine.

Twelve patients with severe renal failure and intercurrent urinary tract infections were treated with either ampicillin trihydrate, 500 mg four times a day, or trimethoprim-sulfamethoxazole, two tablets (80 mg trimethoprim, 400 mg sulfamethoxazole) twice a day. All patients achieved bacteriologic cure, including six with proved upper tract infection. Serum levels of all drugs were increased to values above those seen in normal subjects without adverse effects. Urine concentrations of trimethoprim, 28.6 mug/ml, and ampicillin, 88.6 mug/ml, were well above the minimum inhibitory concentrations of urinary pathogens. Urine sulfamethoxazole concentrations were less than 10 mug/ml in four of the six patients treated; however, this did not hamper bacteriologic success. It is concluded that both drugs can be used to treat urinary tract infections in patients with renal functional impairment.

This paper reports on a 26 year old male who died of toxic diphtheria with all typical features such as: Bullneck, paralysis of the soft palate, renal failure accompanied by proteinuria and--most notably--myocarditis (very typical microscopically) with circulatory disturbances and finally left and right hand failure. The myocarditis hat caused increases of SGOT, SGPT, CPK, LDH and HBDH to values not seen before by us in the course of myocarditis. The patient had been immunized against diphtheria as a child. Initial treatment consisted of the application of ampicillin which caused rapid regression of the local symptoms in the pharyngeal region including the bullneck-symptom; of course the course of intoxication was not influenced, even after the patient had been admitted to the hospital, the disease correctly diagnosed and antitoxin given three days before death.

A case of acute anuric renal failure following hypersensitivity to ampicillin is presented. Renal biopsy showed severe interstitial nephritis. Treatment with prednisolone and heparin, together with supportive measures and peritoneal dialysis, was followed by rapid recovery of renal function. It is concluded that hypersensitivity to ampicillin can cause acute interstitial nephritis, analogous to that seen with penicillin and methicillin.

Ampicillin was tested with regards to its capacity to reduce gastric ammonia production in basal and betazole-stimulated gastric secretion. A 7-day course of oral ampicillin (4 g per day) reduced basal gastric ammonia concentration from 5.5 +/- 1.4 to 1.8 +/- 0.3 mM and postbetazole ammonia from 4.7 +/- 0.9 to 1.3 +/- 0.3 mM (P less than 0.01) in 7 control subjects. Similar results were obtained after oral neomycin (4 g per day) or intramuscular ampicillin (4 g per day), each given to a separate group of 7 control subjects. In 5 azotemic patients, oral ampicillin treatment resulted in a reduction of ammonia concentration from 16.3 +/- 4.7 to 3.1 +/- 0.7 mM in basal secretion and from 18.3 +/- 8.1 to 2.3 +/- 0.6 mM in betazole-stimulated gastric juice (P less than 0.01). Antibiotic therapy did not alter volume of gastric secretion. Gastric acidity appeared lower in azotemic patients and increased significantly after treatment, indicating that the higher ammonia content could account for at least part of the hypoacidity. Because ampicillin is active orally as well as parenterally and can be readily used in renal failure, it may be of value for the treatment of hepatic encephalopathy, especially in the azotemic patient in whom neomycin is toxic.

To reassess the epidemiology and treatment of listeriosis in the United States, we reviewed greater than 120 cases of listeriosis from four medical centers in three geographically separated cities: Los Angeles County-University of Southern California Medical Center (LAC-USCMC); Rush-Presbyterian-St. Luke's Hospital, Chicago; the University of Illinois Hospital, Chicago; and Vanderbilt University Hospital, Nashville, Tennessee. The epidemiological pattern at LAC-USCMC was relatively narrow; more than two-thirds of the cases occurred during the perinatal period. Cases at Vanderbilt University Hospital represented the opposite end of the spectrum; the majority of these occurred in nonpregnant, older adults who had received organ transplants. An intermediate pattern of cases was observed at the two medical centers in Chicago. Potential risk factors included pregnancy, neonatal status, organ transplantation, renal failure, malignancy, systemic lupus erythematosus, steroid therapy, and AIDS (two cases). Antimicrobial agents noted to be effective were, as expected, penicillin and ampicillin; the cephalosporins were ineffective. The mortality associated with listeriosis occurred mainly among premature infants and stillbirths delivered from infected pregnant women and was markedly less among neonates and adults.

The fixed combination antibiotic ampicillin/sulbactam may provide a new, safe, and effective method of treating dialysis-related bacterial peritonitis. The pharmacokinetics of this antibiotic combination were determined in patients receiving continuous ambulatory peritoneal dialysis (CAPD). The pharmacodynamic activity of this drug was also determined by use of mean bactericidal titers against selected bacterial strains. Six noninfected CAPD patients in a randomized two-way crossover study were given a fixed dose of ampicillin (2 gm) and sulbactam (1 gm) either intravenously or intraperitoneally. The mean peak ampicillin and sulbactam serum concentrations following intravenous dosing were 170.3 and 87.5 micrograms/mL, respectively. The mean peak serum concentrations of ampicillin and sulbactam following intraperitoneal dosing were 48.0 and 27.8 micrograms/mL, respectively. Absolute bioavailabilities of the intraperitoneal ampicillin and sulbactam doses were 60% and 68%. Both drugs exhibited similar distribution and elimination characteristics. Renal failure markedly reduced drug elimination. Intraperitoneal administration of ampicillin/sulbactam provided satisfactory inhibitory and bactericidal antibiotic titers for most organisms in dialysate at 6 h but not 24 h. Ampicillin/sulbactam (2 gm/1 gm) should be administered every 12 h to patients with peritoneal dialysis-related peritonitis.

A 3 year old girl was admitted with suspected bacterial meningitis. The patient's history concerning renal and cerebral function and known allergies had been uneventful until that time. 36 h after initiation of a high dose antibiotic therapy with Penicillin G (0.5 Mega IE/kg/day) and Amoxicillin (400 mg/kg/day) macrohematuria and consecutive anuria was observed. Prerenal cardiocirculatory failure, a Schwartz-Bartter-reaction as well as coagulatory failure could be ruled out. There were no symptoms of hypersensitivity. Sonographic examinations of the kidneys and the urinary tract as well as urinanalysis suggested an acute tubular obstruction and papillary necrosis caused by amoxicillin. After changing the antibiotic regimen to chloramphenicol and induction of diuresis by furosemide and dopamine renal failure could be resolved within 39 h. The patient recovered completely. High dose therapy with amoxicillin (greater than 300 mg/kg/day) includes the risk of tubular obstruction due to cristalluria. Solubility of ampicillin in aqueous fluids (6.5 mg/ml at pH 7) should be supported by sufficient diuresis and urine alkalization.

The single-dose pharmacokinetics of intravenously administered ampicillin (2.0 g) and sulbactam (1.0 g) were studied in normal subjects and in patients with various degrees of creatinine clearance (CLCR). Six normal subjects (CLCR, greater than 60 ml/min), six patients with mild renal failure (CLCR, 31 to 60 ml/min), four patients with severe renal failure (CLCR, 7 to 30 ml/min), and four patients requiring maintenance hemodialysis (CLCR, less than 7 ml/min) were studied. The terminal half-lives for ampicillin and sulbactam more than doubled in patients with severe renal failure compared with subjects with normal renal function and mild renal insufficiency. CLCR significantly correlated with ampicillin (r = 0.88) and sulbactam (r = 0.54) total body clearance. Mean steady-state volume of distribution and nonrenal clearance for ampicillin and sulbactam were not affected by renal function. Hemodialysis approximately doubled the ampicillin and sulbactam total body clearance. Mean totals of 34.8 +/- 4.0% of the ampicillin dose and 44.7 +/- 3.2% of the sulbactam dose were removed during a 4-h hemodialysis treatment. A slight rebound in concentrations in serum after hemodialysis was observed for both drugs in all four subjects. In hemodialysis patients, the ampicillin half-life was 17.4 +/- 8.0 h and the sulbactam half-life was 13.4 +/- 7.4 h. The ampicillin and sulbactam half-lives were appreciably altered during the hemodialysis period (means of 2.2 and 2.3 h, respectively). The nearly parallel decrease in total body clearance, with volume of distribution and nonrenal clearance remaining relatively constant, suggests that the same ratio of ampicillin to sulbactam is appropriate regardless of renal function. An adjustment of the ampicillin (2.0 g) and sulbactam (1.0 g) dose to twice daily would be appropriate in patients with a CLCR between 7 and 30 ml/min. Doses should be given every 24 h for those undergoing maintenance hemodialysis. On hemodialysis days, doses should be given after hemodialysis.

To determine whether surgery could be avoided in some patients with perforated peptic ulcer, we conducted a prospective randomized trial comparing the outcome of nonoperative treatment with that of emergency surgery in patients with a clinical diagnosis of perforated peptic ulcer. Of the 83 patients entered in the study over a 13-month period, 40 were randomly assigned to conservative treatment, which consisted of resuscitation with intravenous fluids, institution of nasogastric suction, and intravenous administration of antibiotics (cefuroxime, ampicillin, and metronidazole) and ranitidine. Eleven of these patients (28 percent) had no clinical improvement after 12 hours and required an operation. Two of the 11 had a perforated gastric carcinoma, and 1 had a perforated sigmoid carcinoma. The other 43 patients were assigned to immediate laparotomy and repair of the perforation. One of these patients was found to have a perforated gastric carcinoma. The overall mortality rates in the two groups were similar (two deaths in each, 5 percent), and did not differ significantly in the morbidity (infection, cardiac failure, or renal failure) rates (40 percent in the surgical group and 50 percent in the nonsurgical group). The hospital stay was 35 percent longer in the group treated conservatively. Patients over 70 years old were less likely to respond to conservative treatment than younger patients (P less than 0.05). We conclude that in patients with perforated peptic ulcer, an initial period of nonoperative treatment with careful observation may be safely allowed except in patients over 70 years old, and that the use of such an observation period can obviate the need for emergency surgery in more than 70 percent of patients.
