The frequency of severe reactions to allopurinol has probably been underestimated. A retrospective study encompassing a five-year period has yielded 20 patients with severe hypersensitivity reactions to allopurinol. Patients with preexisting renal impairment or who were receiving concomitant thiazide diuretics appeared to be especially predisposed. Cutaneous reaction patterns included maculopapular eruptions, exfoliative dermatitis, and toxic epidermal necrolysis. eosinophilia was uncommon. Forty percent of the patients developed hepatic involvement and 45% had renal involvement. Hepatic and renal changes usually were reversible and were not unique to any one cutaneous reaction pattern. Three patients with renal involvement required prolonged administration of systemic steroids. Complications included sepsis, decubitus ulcers, and thromboembolism. Two patients required hyperalimentation. Sequelae included dry eyes, pigmentary disturbances, and keloids. Three patients died as a result of their reaction. It is concluded that allopurinol should be used only in select patients, and the dosage should be modified if renal disease exists.

Case records of 1,098 patients treated with amikacin at 79 research centers in 10 countries in a program of worldwide clinical trials were reviewed. Of the 697 patients eligible for use in evaluation of efficacy of the drug, 81% were cured, as evidenced by clinical remission and eradication of the infecting pathogen. The usual dosage was 7.5 mg/kg administered intramuscularly at 12-hr intervals. This dosage was modified in patients with renal impairment. Amikacin was effective in 90% of 322 patients with genitourinary infections, 85% of 97 patients with septicemia, 70% of 73 patients with infections of skin, soft tissue, or bone (excluding burns), and 69% of 68 patients with infections of the lower respiratory tract. Amikacin was effective in treatment of 88% of 85 infections due to gentamicin-resistant pathogens. The drug was generally well tolerated, and no side effects were reported in 80.6% of the 1,098 patients evaluated. Amikacin shares with other aminoglycosides the risk of ototoxicity and nephtotoxicity; previous exposure to gentamicin was a major factor in the development of such adverse effects. Other adverse reactions were relatively infrequent and in most cases were characterized as mild and transient.

Obstructive jaundice is frequently associated with septic complications and renal impairment. The present study was performed in order to evaluate reticuloendothelial system (RES) function in obstructive jaundice and the influence of a septic challenge. Male Sprague-Dawley rats were allocated into four groups (laparotomy alone, caecal ligation and puncture (CLP), ligation of the common bile duct (CBD) alone and CBD+CLP, respectively). Mortality, blood clearance and organ distribution of 125I labelled Escherichia coli were determined. Mortality in sepsis (CLP) significantly increased in jaundiced animals (p less than 0.033). Blood clearance of radiolabelled E. coli was significantly impaired in both jaundiced groups. In jaundiced animals, hepatic localisation and renal uptake of E. coli significantly increased (p less than 0.001), while radioactive counts in bile significantly decreased (p less than 0.01). Changes in organ distribution of bacteria did not depend on alterations in blood flow. Thus, RES function was impaired in jaundiced animals and mortality increased in a concomitant septic challenge in jaundiced animals.

A 39 year old woman presented with a short history of bloody diarrhoea. She subsequently developed microangiopathic haemolysis, platelet consumption, and renal impairment. Initial investigations suggested underlying Crohn's disease of the terminal ileum complicated by sepsis and disseminated intravascular coagulation. However, after resection of a perforated caecum and terminal ileum, the diagnosis of thrombotic thrombocytopenic purpura was made. There was weak serological evidence of yersinia infection, this may have caused the early localisation of the lesions to the terminal ileum. This is believed to be the first report of thrombotic thrombocytopenic purpura affecting the small bowel alone at presentation.

Thoracoabdominal aortic reconstruction distal to the left subclavian artery was carried out on 19 patients between 1974 and 1990. Screening procedures to detect cardiac, respiratory or renal impairment were undertaken in all patients. Reconstruction was in the upper third of the descending aorta in 6 patients, middle third in 6 patients, and lower third in 7 patients. The Crawford inclusion technique was used in all cases. There were six deaths, four of which were from the high reconstruction group, and one each from the middle and lower group. Paraparesis occurred in 4 patients, 2 of whom survived with some impairment. Temporary renal failure was seen in 2 patients, liver failure in 2, respiratory failure in 2, sepsis in 1, myocardial infarction in 1, and severe coagulopathy in 3. The perioperative mortality rate was 32% for the group as a whole and 15% for reconstructions which started at the middle or lower thoracic level. We conclude that the mortality rate for the middle and lower reconstructions is acceptable but that alternative techniques for the high aneurysms should be sought.

Fourteen patients with Wegener's granulomatosis (WG) and severe renal and extrarenal involvement were studied (serum creatinine on admission 5.8 +/- 3.4 mg/dl). Renal histology showed a necrotizing, crescentic glomerulonephritis in all patients. Despite advanced renal disease on admission cyclophosphamide, steroids (in 13 patients) and plasma exchange (in 9 patients) caused a rapid and sustained improvement of renal function. Four patients required intermittent hemodialysis over a period of one week. After 2 weeks of treatment serum creatinine values below 2 mg/dl (n = 4) indicated a nearly complete recovery of renal function in the long-term follow up (mean serum creatinine achieved after 12 months therapy: 1.1 +/- 0.1 mg/dl (n = 4). Therefore serum creatinine values observed after 2 weeks of therapy, appear to be of prognostic value with regard to renal outcome. No relapse of active WG or progressive renal deterioration was observed during follow-up (22 +/- 13 months) except in one patient with persisting renal impairment. Three patients died (staphylococcus sepsis, intracerebral hemorrhage during hypertensive crisis, pulmonary embolism) during the first two months of therapy. The decline of serum creatinine seemed to be a better indicator of successful therapy than the decrease of anticytoplasmatic antibody (ANCA), erythrocyte sedimentation rate (ESR) and hematuria. On admission ANCA titer neither correlated with serum creatinine, the degree of renal involvement, nor was it of prognostic value. ANCA, serum creatinine and hematuria normalized within 2 to 8 months, whereas ESR and proteinuria remained elevated. Our data indicate a good prognosis of WG even with advanced renal involvement and generalized vasculitis provided aggressive treatment is performed early.

The monobactam antibiotics are synthetic compounds, although monocyclic beta-lactam compounds have been found in nature in various soil bacteria. Although additional orally and parenterally administered monobactams are under investigation, the first marketed monobactam was aztreonam. This agent has an antimicrobial spectrum similar to that of gentamicin and tobramycin, aminoglycoside antibiotics. Aztreonam, however, is not nephrotoxic, is weakly immunogenic, and has not been associated with disorders of coagulation. Aztreonam may be administered intramuscularly or intravenously; absorption after oral administration is poor. The primary route of elimination is the urine. The serum half-life of the drug in patients with normal renal function is 1.5 to 2.1 hours; the recommended dosing interval in patients with normal renal function is every 8 hours. Dosage adjustment is necessary in patients with renal impairment. The strictly gram-negative aerobic spectrum of aztreonam limits its use as a single empiric agent. Approved indications for its use include infections of the urinary tract or lower respiratory tract, intra-abdominal and gynecologic infections, septicemia, and cutaneous infections caused by susceptible organisms. Concurrent initial therapy with other antimicrobial agents is recommended before the causative organism (or organisms) has been determined in patients who are seriously ill and at risk for gram-positive or anaerobic infections.

A woman with a history of drug allergy, renal impairment and carcinoma of the breast with pulmonary micrometastases developed haemolytic anaemia and Stevens-Johnson syndrome following the use of mefenamic acid, paracetamol (acetaminophen) and furosemide (frusemide). In addition there was severe cholestatic hepatitis in the absence of clinical evidence of sepsis, biliary obstruction or recurrent metastases. The rash resolved on steroid therapy but the patient eventually died from both renal and liver failure. Acute tubular necrosis with a background of chronic tubulointerstitial nephritis was also found at autopsy. Although in the presence of multiple drug therapy the causative agent cannot be identified with absolute certainty, the association of these severe idiosyncratic hepatic and dermatological reactions with haemolytic anaemia strongly suggests mefenamic acid as the most likely culprit.

We performed bone scans with 99mTechnetium phosphates in 15 cases of clinically suspected rhabdomyolysis admitted to Chigasaki Tokushukai Hospital. Whole body scans were performed within 5 days from the onset of illness or admission. Accumulation of the radioactivity in the skeletal muscle was revealed in 13 of the 15 cases and the involved muscle groups were visualized vividly. Etiologies of rhabdomyolysis were diverse, ranging from malignant syndrome to sepsis. Myocardial concentration was absent in all of the cases. Renal concentration of the isotope was seen in cases where the degree of rhabdomyolysis was higher and renal impairment was present. We conclude that 99mTechnetium phosphate bone scan is useful in clinically suspected rhabdomyolysis as a diagnostic test and as a test to localize and quantitate the muscular involvement.

Aztreonam, the first monobactam, has been used extensively in the treatment of a variety of infections caused by gram-negative pathogens. It has been shown to be highly effective against susceptible bacteria without causing serious adverse reactions. Its pharmacologic profile can be attributed to its unique chemical properties and mechanisms of action, which differ substantially from those of the bicyclic beta-lactams, such as the penicillins and cephalosporins. Administered parenterally, aztreonam provides peak serum concentrations for most Enterobacteriaceae and Pseudomonas aeruginosa. It is widely distributed throughout the body. Excretion is largely dependent on renal mechanisms, so dosage can be adjusted in the presence of renal impairment. The clinical uses of aztreonam include treatment of urinary tract, lower respiratory tract, and intraabdominal infections, as well as septicemia, endometritis, pelvic cellulitis, and skin and skin structure infections due to aerobic gram-negative organisms. It is concluded that aztreonam can be used with confidence in the single-drug treatment of susceptible aerobic, gram-negative pathogens. In the treatment of mixed infections, or those of unknown etiology, however, combination therapy is recommended to ensure coverage of gram-positive and anaerobic bacteria.
