Serum gamma-glutamyltranspeptidase (GGTP) and alpha-amylase clearance were determined in a total group of 90 patients of whom 60 with renal diseases and 30 with extrarenal diseases. The renal patients were distributed, according to diagnosis in the following groups: acute glomerulonephritis, chronic glomerulonephritis, acute pyelonephritis, chronic pyelonephritis, nephrotic syndrome and manifest chronic renal failure. The 30 controls were hospitalized for different extrarenal diseases such as:
pneumonia
, gastroduodenal ulcer, arterial hypertension stage I and angina pectoris. Serum GGTP assay was performed in 60 patients (40 renal patients and 20 controls) using Boehringer monotest kits and in 30 patients (20 renal patients and 10 controls) using Romanian kits (I.C.C.F.). No changes suggesting a particular type of nephropathy were observed. The results obtained by using the two types of kits for the serum GGTP assay have proved to be very close. Alpha-amylase clearance was determined in all the patients with Spofa (R.S.C.) tablets concomitantly with the urea and
creatinine
clearance. Important decreases of alpha-amylase clearance in concordance with decreases of urea and
creatinine
clearances were observed in all the patients with severe renal failure. More moderate decreases of alpha-amylase clearance were observed in the patients with acute and chronic glomerulonephritis. The utility of this clearance as a test of glomerular filtration and sometimes as a prognostic test, is discussed.

The pharmacokinetics of the antiviral drug 9-[2-hydroxy-1-(hydroxymethyl) ethoxymethyl]guanine (DHPG) were examined in six patients receiving 2.5 or 5.0 mg/kg every 8 or 12 hours for human cytomegalovirus (HCMV)
pneumonitis
or retinitis. Biexponential decay with a mean distribution t1/2 of 0.23 hours and terminal t1/2 of 2.53 hours was observed. Total clearance correlated well with and exceeded
creatinine
clearance by a factor of 2.4. Mean volume of the central compartment was 15.26 L/1.73 m2 and the volume of distribution at steady state was 32.8 L/1.73 m2. Peak (model predicted) and trough plasma concentrations were 4.75 to 6.20 micrograms/ml and less than 0.25 to 0.63 microgram/ml, respectively, in patients receiving 2.5 mg/kg. Peak concentrations are well above those needed to inhibit HCMV at the 50% level (ID50) and troughs are near this ID50. Cerebrospinal fluid concentrations of DHPG indicate a penetration of 24% to 67%. No accumulation of DHPG was apparent in these patients. However, dosage reduction is necessary in renal insufficiency. Neutropenia occurred in one patient. The plasma concentration profile of DHPG suggests potential beneficial activity against HCMV.

Foscarnet was administered to eight AIDS patients for suspected cytomegalovirus (CMV)
pneumonitis
as a continuous intravenous infusion for a minimum of 8 days. All the patients improved, three showing complete resolution of symptoms. Evidence of CMV infection from bronchoalveolar lavage samples was lacking in two patients. Adverse drug experiences consisted of thrombophlebitis, transient decreases in haemoglobin concentration, and reversible rises in serum
creatinine
levels.

Between January 1984 and December 1985, 183 adult patients, subsequently shown to have pneumococcal bacteraemia, were admitted. Of these infections, nine were caused by penicillin-resistant strains, and three of these were resistant to other antibiotics. The organisms from 150 patients were serotyped/grouped. The primary site of infection was lung in 90 per cent of patients. Among the patients with
pneumonia
, those with serovar 3 strains accounted for most intensive care unit admissions, most cases requiring inotropic drugs, and mechanical ventilation and had the highest complication rate and mortality. Findings which predicted the need for intensive care included higher age, elevated concentrations of serum urea,
creatinine
, and phosphate and lower levels of total serum protein, albumin and calcium. Twenty-four patients died of whom 23 had
pneumonia
. The case fatality rate among all of the patients admitted to the intensive care unit was 60 per cent and among those not admitted to the unit, 9.2 per cent. Of the patients who died, 41.7 per cent did so within the first five days of admission. The prophylactic use of polyvalent pneumococcal vaccine in industrial workers from low socio-economic groups should be carefully considered.

A small tear in the urinary bladder of a severely debilitated 4-day-old foal was managed with an indwelling urinary catheter connected to a urine collecting system. Fluid therapy, parenteral nutrition, and antimicrobial agents were used during the initial management of the ruptured bladder. Aseptic technique for catheter care and systemic administration of antimicrobial agents prevented the development of bacterial cystitis. Catheter management required constant monitoring, but the bladder defect was sealed within 5 days. Fungal arthritis caused by Candida tropicalis, immune-mediated anemia, diarrhea, constipation, venous thrombosis, and
pneumonia
were observed during 43 days of hospitalization. Although the foal died at 3 months of age, serum
creatinine
concentration and electrolyte values remained within normal limits during the 3-month period.

We prospectively studied 51 consecutive bacteremic patients with chronic liver disease in order to evaluate their clinical presentation and to assess the relationship of various clinical parameters to mortality. Forty-two patients had alcoholic liver disease and 40 were in Class C, by the Pugh modification of Child's criteria. Soft tissue infections were the most common source of bacteremia, followed by
pneumonia
, spontaneous bacterial peritonitis and urinary tract infection. Gram positive organisms were isolated in 69% of cases, and Gram negative ones in 31%. In nine patients, no source of bacteremia was detected. Leukocytosis occurred in 59% of patients and bandemia in only 41%. Although appropriate antibiotic therapy was begun in all cases on admission, 17 patients (33%) died in the hospital. Of 38 clinical parameters evaluated, multivariate analysis revealed that the three variables contributing the most independent information toward predicting in-hospital mortality were the absence of a history of fever, an elevated serum
creatinine
and marked leukocytosis. Improved understanding of the pathophysiologic relationship between these parameters and patient outcome may enable us to improve the therapy of bacteremic patients with chronic liver disease.

Although various complications such as electrolyte imbalance and urinary infection are known to be induced by ureterosigmoidostomy, it is still a surgical technique difficult to ignore since it allows patients to lead an almost normal life without the encumbrance of external urinary devices. At our hospital, we performed eighteen ureterosigmoidostomy operations between 1976 and 1985. Herein, we review the postoperative conditions of electrolyte, renal function and other complications. The patients (16 male, 2 female) were between 53 and 72 years old, the mean age being 61.5 years. The primary diseases were bladder tumor (14 patients), prostatic cancer (2), carcinoma of the female urethral diverticulum (1) and urethral stricture (1). As to the electrolytes, both serum Na and serum K values fluctuated within the normal range. Hyperchloremia was detected in 4 cases (22.2%), but it was only slightly above the normal range and the conditions were more or less stabilized a year after the operation. Although blood urea nitrogen had a tendency to elevate one or two years after the operation, serum
creatinine
fluctuated within the normal range. During the observation period, only 7 of the 18 cases (38.9%) showed complications, the major complication being pyelonephritis (3 cases). Postoperative excretory urogram revealed slight to medium hydronephrosis two months after the operation in 9 of the 18 cases (50%), but most of these conditions were normalized within a year. Four patients died after leaving hospital; 3 due to the recurrence of cancer and one due to
pneumonia
. The 14 other outpatients are enjoying a normal life without the use of any external urinary device.

In a randomized prospective study, two different regimens of antibiotic prophylaxis have been tested: four-day cefazolin prophylaxis (Kefzol 0.5 gr every 6 h) compared with two-day cefuroxime administration (Zinacef 1.5 gr every 12 h). A total of 569 patients in the two groups were studied in a 10 month period. Haematological, liver function, serum
creatinine
and urea measurement were made preoperatively and repeated daily for the first four days and after one week. At least five chest X-rays were taken during the hospitalisation. Body temperature was measured regularly every two hours in the ICU and a least twice a day thereafter. The wounds were examined daily and the patients were carefully observed for other infections. Bacteriological examinations of the tips of all inserted catheters and pacemaker wires were undertaken on removal in the first four months of the trial. Swabs of any tracheal or wound secretion or pus taken for bacteriological examinations as also blood cultures in any suspected septicaemia. Of the 569 patients three had to be withdrawn from the study. Of the assessable ones 285 received cefuroxime and 281 were given cefazolin. Seven patients (1.2%) died postoperatively. The total infection rate was 5.5%: 5.7% in the cefazolin group and 5.3% in the cefuroxime group. The overall wound infection rate was 1.8%: 2.5% in the cefazolin group and 1.1% in the cefuroxime group. Septicaemia occurred in 0.5% of the cases.
Pneumonia
occurred in 11 (1.9%) patients; 1.5% in the cefazolin and 2.5% in the cefuroxime group. Seven patients (1.2%) developed a urinary tract infection; 1.4% in the cefazolin group and 1.1% in the cefuroxime group.(ABSTRACT TRUNCATED AT 250 WORDS)

Elevated plasma renin activity (PRA) has been documented in patients with established acute renal failure. To study the association of PRA and renal dysfunction, 53 patients who were at risk of developing acute renal failure had serial measurements of PRA, renal function, and urinary beta 2-microglobulin. Those entered for study had
pneumonia
, septicaemia, volume loss with hypotension, or major surgical procedures with complications. Patients were divided into groups of abnormal or normal renal function. Abnormal renal function was defined by an elevated plasma urea and/or
creatinine
level with a submaximal urine urea to plasma urea ratio. The mean values of PRA for the abnormal and normal renal function groups, respectively, were 29 and 5.2 ng/ml/h (p less than 0.0001) and for beta 2-microglobulin 16.2 and 6.4 micrograms/l X 10(3) (p less than 0.0005). A linear regression of the logs of PRA to beta 2-microglobulin for the total group of patients gave an r value of 0.526 (p less than 0.001). These data show an association of PRA to renal dysfunction and tubular injury/dysfunction in the prerenal phase of renal failure, suggesting an effect of the renin-angiotensin system at this phase. It is not possible, however, to conclude from our study that the renin-angiotensin system has a direct role in the development of established acute tubular necrosis, since only 3 patients fell within this category.

Thirty-five patients with serious infections and impaired renal function were treated empirically with 2 to 8 g of cefoperazone per day. Infections included sepsis in 14, nonbacteremic urinary infections in nine,
pneumonia
in five, intra-abdominal infection in five, fasciitis in one, and malignant otitis externa in one. The average age of this group was 64.3 years, 25 had ultimately fatal underlying diseases, and their average serum
creatinine
level was 5.2 mg/dl. Infections were caused by Enterobacteriaceae in 23 patients, Streptococcus faecalis in five, Pseudomonas aeruginosa in four, Staphylococcus aureus in four, Hemophilus influenzae in three, and Staphylococcus epidermidis, Streptococcus pneumoniae, and Clostridium sordelli in one each. Overall, 32 patients had clinical and microbiologic cures, two had improvement, and one had failure. Hypoprothrombinemia occurred in 18 of 28 patients not given vitamin K for prophylaxis and occurred more often in those with serum albumin concentrations below 3.5 g/dl. Prothrombin times returned to normal within 36 hours of treatment with vitamin K, although two patients experienced mild hematemesis. In anicteric patients with liver function abnormalities, 2 g every 12 hours produced peak and trough serum concentrations that averaged 254 and 125 micrograms/ml, respectively, compared with 179.5 and 19.5 micrograms/ml, respectively, in five with normal liver function test results. In jaundiced patients treated with 1 g every 12 hours, trough concentrations were comparably elevated. Serum concentrations did not correlate with hypoprothrombinemia, but high levels throughout the dosing interval may have contributed to the excellent cure rate in this study.
