Abstract
Azithromycin, a broad-spectrum azalide, and co-amoxiclav were compared in a randomized, multicentre, open-label trial in 759 patients treated for acute tracheobronchitis (n = 620) or acute infectious exacerbations of chronic bronchitis (n = 139). Patients were randomized (2:1) to a 3-day regimen of two azithromycin 250 mg capsules once daily or a 5-10-day regimen of co-amoxiclav, one 625 mg tablet three times daily. Azithromycin produced a significantly higher cure rate (70.6% versus 61.1%) than co-amoxiclav (P = 0.011) and there were fewer failures (7.8% versus 13.6%) and relapses in the azithromycin-treated group, giving a higher overall response rate for azithromycin (89.7% versus 80.2%, P = 0.0003). With azithromycin, compliance was better than with co-amoxiclav and there was a significantly shorter time to improvement or cure. A higher incidence of adverse events, mostly gastrointestinal, was reported by patients taking co-amoxiclav (21.3% versus 14%, P = 0.0097), causing more patients in this group to discontinue therapy (7% versus 1.2%, P = 0.00004).

Abstract
Amoxycillin/clavulanic acid liver injury is very rare. We describe an exceptional case of intrahepatic cholestasis without hepatitis induced by amoxycillin/clavulanic acid. Recognition of this benign cholestatic syndrome as a side-effect may obviate unnecessary complementary and costly procedures.

Abstract
AIMS To review spontaneous reports of drug-associated adverse hepatic reactions. METHODS Reports of drug-associated adverse hepatic reactions received by the New Zealand Centre for Adverse Reactions Monitoring over the 21 year period January 1974 to December 1994 were reviewed. Subdivision into three 7 year periods was undertaken to compare patterns. RESULTS Of a total of 22,455 adverse medicine reaction (AMR) reports there were 943 reports of liver injury (4.2%). Two hundred and five drugs were associated with hepatic reactions. The top 20 drugs accounted for 57% of all liver reactions. Fifty-seven percent were reported in females. Hepatotoxicity was most commonly reported among patients 50-80 years old. Liver reactions were associated with a 3.3% mortality, but were responsible for 7.4% of all fatal occurrences. There was a steady increase in the number of reports over the 21 years. Although the largest number of reports of liver injury were received between 1988 and 1994, mortality was lowest during this period. There were substantial differences in the medicines associated with hepatic reactions during each of the three periods, although erythromycin was the commonest cause throughout. Erythromycin was associated with two deaths. Halothane and perhexilene were the most frequent cause of death and were two of the most important causes of liver injury during the first and second periods. Diclofenac, Augmentin and flucloxacillin were important causes of hepatotoxicity during period 3 but were not associated with a fatal outcome. CONCLUSION Hepatic reactions accounted for 4.2% of all adverse medicine reactions and 7.4% of all fatal occurrences. The top 20 drugs were responsible for 57% of all liver reactions. Despite a steady increase in the number of reports during the 21 years, mortality was lowest during the last 7 years. Differences in the medicines causing liver injury during the three periods influenced the number of fatalities. Erythromycin was the most commonly reported cause of hepatic reactions but was usually associated with a favourable outcome. There were no reported deaths with diclofenac, Augmentin or flucloxacillin.

Abstract
Seventy-five pregnant women (mean gestational age 32.26 weeks, range 20-36 weeks) with premature rupture of the membranes (PROM) were admitted in our department during 1989 and the first 6 months of 1990. Amoxicillin and clavulanic acid was initially administered at a dose of 1.2 g i.v. every 8 hours for 3-4 days and was followed by oral administration of 625 mg every 8 hours until labor. Sixty-one patients (mean gestational age 32.6 +/- 2.3 weeks, range 26-36 weeks) achieved an uncomplicated course of their pregnancies with a mean time of 11.4 +/- 5.7 days (range 3-27 days), from rupture to delivery. Fourteen women (mean gestational age 30.8 +/- 5 weeks, range 20-36 weeks) developed chorioamnionitis 3.5 +/- 0.9 days (range 1.4-5.6 days) after the rupture with several degrees of leukocyte infiltration of the membranes, placenta and the umbilical cord. Five women (mean gestational age 23.8 +/- 2.3 weeks, range 20-26 weeks) had complications resulting in fetal/infant death, three of them because of fetal sepsis (Escherichia coli, Pseudomonas aeroginosa, Staphylococcus aureus). The newborns were followed up 6 months from delivery and had no signs of drug influence. Few side effects were observed with the chief complaints involving the gastrointestinal tract (4%). No one discontinued the drug. It seems therefore, that the prophylactic administration of amoxicillin and cluvalanic acid in women with PROM is associated with a significant prolongation of pregnancy and with a reduction in the incidence of fetal/maternal infections.

Abstract
BACKGROUND Amoxicillin-clavulanic acid combination-associated hepatitis and jaundice was first identified in 1988. Numerous case reports and case series have been published since then, but there is no precise estimate of this risk. METHODS A retrospective cohort study in the United Kingdom to estimate the risk of acute liver injury associated with the combination of amoxicillin and clavulanic acid and compare it with the one of amoxicillin alone. Data were derived from a cohort of 93,433 users of the combination drug amoxicillin-clavulanic acid and 360,333 users of amoxicillin alone who were aged between 10 and 79 years and who were followed up from 1991 through 1992. After reviewing the information on subjects with suspected liver injury that was recorded on computer files, the clinical records of 177 patients from the attending general practitioners were requested. RESULTS They were 35 cases of idiopathic acute liver injury. None was fatal. There were 14 cases of acute liver injury among users of amoxicillin alone. The type of liver injury was hepatocellular in half the cases. There were 21 cases of acute liver injury among users of amoxicillin and clavulanic acid together. The type of liver injury was cholestatic in three quarters of the cases. The incidence rates and 95% confidence intervals (CIs) of developing acute liver injury associated with the combination of amoxicillin and clavulanic acid and amoxicillin alone were 1.7 (1.1-2.7) and 0.3 (.02-0.5) per 10 000 prescriptions, respectively. The rate ratios and 95% CIs of acute liver injury for amoxicillin and clavulanic acid together compared with amoxicillin alone were 6.3 (3.2-12.7) for all patients and 8.4 (3.6-20.8) for patients presenting with jaundice. Among users of amoxicillin and clavulanic acid together, the risk of developing acute liver injury was more than 3 times greater after a course of 2 or more consecutive prescriptions than after a single course of therapy. The risk also increased with age among users of amoxicillin and clavulanic acid together. The combination of advancing age and repeated prescriptions resulted in a risk of developing acute liver injury greater than 1 per 1000 users of amoxicillin and clavulanic acid together.

Abstract
OBJECTIVE Evaluate antibiotic-associated diarrhea and toxigenic Clostridium difficile in stool specimens obtained from children before and after 10 days of amoxicillin/clavulanate for otitis media. DESIGN Children, 12 to 47 months of age, treated with amoxicillin/clavulanate for otitis media in an outpatient setting were enrolled. Stool specimens were obtained at enrollment, when diarrhea occurred and at the end of therapy. All stool specimens were tested for C. difficile toxins A and B by enzyme immunoassay. RESULTS Seventy-six children who had stool specimens collected at enrollment and after therapy were included in the analysis. None had C. difficile toxin in stool specimens at enrollment. Six (27%) of 22 children with diarrhea, and 4 (7%) of 54 children without diarrhea had C. difficile toxin present at completion of therapy (P = 0.03). CONCLUSION Toxigenic C. difficile was identified in 13% of children at the conclusion of amoxicillin/clavulanate therapy with a significantly higher frequency in children with diarrhea.

Abstract
A 3-day regimen of azithromycin (500 mg once daily) and a 10-day regimen of co-amoxiclav (625 mg three times daily) were compared in a double-blind study of 67 patients with acute infectious exacerbations of chronic bronchitis (AIECBs, n = 54), acute bronchitis (n = 7), or pneumonia (n = 6). In patients treated with azithromycin, satisfactory clinical responses (cure or improvement) were seen in 24/28 (86%) patients with AIECBs, 2/4 (50%) with acute bronchitis and 2/2 (100%) with pneumonia. Responses were satisfactory in 24/26 (92%), 4/4 (100%) and 4/4 (100%) patients, respectively, receiving co-amoxiclav. Streptococcus pneumoniae and Haemophilus influenzae were the commonest pathogens isolated at baseline. At the end of treatment, baseline pathogens were eradicated in 9/10 microbiologically-assessable patients treated with azithromycin and in 10/10 treated with co-amoxiclav. Adverse events related or possibly related to treatment occurred in five patients in each treatment group; the majority of these events affected the gastrointestinal system. One patient in each treatment group discontinued therapy because of adverse events. The study, therefore, demonstrates that 500 mg azithromycin administered once daily for 3 days is as efficacious and well tolerated as co-amoxiclav given three times daily for 10 days in the domiciliary treatment of adults with acute lower respiratory tract infections.

Abstract
Clinical and bacteriological efficacy and tolerability of azithromycin (500 mg once daily for 3 days) and those of a 10-day regimen of co-amoxiclav (37 mg three times daily) were evaluated in a large-scale, double-blind comparative study of 369 patients (> or = 18 years old) with acute lower respiratory tract infections. After treatment, 165/173 (95%) azithromycin- and 166/173 (96%) co-amoxiclav-treated patients had responded satisfactorily (cure or improvement). Baseline pathogens (mainly Streptococcus pneumoniae and Haemophilus influenzae) were eradicated in 82/82 (100%) azithromycin- and 73/74 (99%) co-amoxiclav-treated patients who were bacteriologically assessable. Adverse events, which were predominantly of mild to moderate severity and mostly affected the gastrointestinal system, were recorded in 13/186 (7%) azithromycin- and 19/183 (10%) co-amoxiclav-treated patients. Only two (1%) azithromycin-treated patients discontinued treatment due to adverse events compared with eight (4%) who received co-amoxiclav. The results show that azithromycin at a dose of 500 mg once daily for 3 days is an effective and safe alternative to a 10-day, three-times-daily course of co-amoxiclav in the treatment of lower respiratory tract infections in adults.

Abstract
Cefuroxime axetil has been evaluated previously in the treatment of lower respiratory tract infections, but not specifically in the treatment of community-acquired pneumonia. In a multicentre, investigator-blinded clinical trial, 162 patients with community-acquired pneumonia were randomly assigned to receive orally either cefuroxime axetil 500 mg bid (n = 84) or amoxycillin/clavulanate 500 mg/125 mg tid (n = 78) for 10 days. Organisms were isolated from the pretreatment sputum specimens of 97 of 162 (60%) patients, the commonest isolates being Streptococcus pneumoniae (38%) and Haemophilus influenzae (18%). A satisfactory clinical outcome (cure or improvement) was achieved in 100% (55 of 55) and 96% (49 of 51) of the clinically evaluable patients treated with cefuroxime axetil or amoxycillin/clavulanate, respectively (P = 0.23). With respect to eradication of bacterial pathogens, a satisfactory outcome (cure, presumed cure or cure with colonization) was obtained in 94% (32 of 34) and 93% (37 of 40) of bacteriologically evaluable patients treated with cefuroxime axetil or amoxycillin/clavulanate, respectively (P = 1.00). Both treatment regimens used in this study were well tolerated. The most common drug-related adverse experiences were gastrointestinal events, reported by 8% and 4%, respectively, of the patients in the amoxycillin/clavulanate and cefuroxime axetil groups, a difference which was not statistically significant (P = 0.32). These results indicate that cefuroxime axetil twice a day is as effective as amoxycillin/clavulanate three times a day in the treatment of outpatients with mild to moderate community-acquired pneumonia.

Abstract
BACKGROUND In recent years there has been considerable interest in reducing the duration of antibiotic treatment regimens in patients with common bacterial infections. We conducted two independent, investigator-blinded, multicenter, randomized clinical trials, one of which included microbiologic evaluation of middle ear fluid obtained by tympanocentesis, comparing the efficacy and safety of 5 or 10 days of treatment with cefuroxime axetil suspension (CAE) with that of 10 days of treatment with amoxicillin/clavulanate suspension (AMX/CL) in children with acute otitis media. METHODS A total of 719 pediatric patients from the ages of 3 months to 12 years were enrolled in the 2 studies. Patients received CAE for either 5 or 10 days at 30 mg/kg/day in 2 divided doses (n = 242 and 235, respectively) or AMX/CL for 10 days at 40 mg/kg/day in 3 divided doses (n = 242). Patients in the CAE (5 days) group received placebo on Days 6 through 10. In the study that included tympanocentesis, bacteriologic assessments were based on middle ear fluid cultures obtained pretreatment and, when possible, after treatment in patients with an unsatisfactory clinical outcome. RESULTS Organisms were isolated from the pretreatment middle ear fluid specimens of 177 of 244 (73%) patients undergoing tympanocentesis, with the primary pathogens being Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis (37, 35 and 12% of isolates, respectively). Pathogens were eradicated or presumed to be eradicated in 92% (24 of 26), 84% (32 of 38) and 95% (36 of 38) of bacteriologically evaluable patients treated with CAE for 5 or 10 days or with AMX/CL, respectively. A satisfactory clinical outcome (cure or improvement) occurred in 69% (101 of 147), 70% (121 of 173) and 74% (131 of 177) of clinically evaluable patients treated with CAE (5 days), CAE (10 days) or AMX/CL, respectively. Treatment with AMX/CL was associated with a significantly higher incidence of drug-related adverse events than was treatment with CAE for either 5 or 10 days (P < 0.001), primarily reflecting a higher incidence of drug-related gastrointestinal adverse events (34% vs. 17 and 12%, respectively; P < 0.001), particularly diarrhea. CONCLUSIONS Treatment with CAE given twice daily for 5 days is equivalent to treatment for 10 days either with the same regimen of CAE or with AMX/CL given three times daily in pediatric patients with acute otitis media.

Abstract
The association amoxicillin-clavulanic acid is a widely used medication. Only about 15 cases of cholestatic hepatitis were reported in Belgium between 1990 and 1993; about 100 cases have been reported to the pharmaceutical company. This effect is severe but reversible. The injury is probably idiosyncratic or immunologically based. Age, sex and treatment duration are as many agents of risk. The diagnosis is undertaken on basis of clinical examination, chronological study, biological evolution and histology.

Abstract
The treatment of community-acquired pneumonia is empirical in most cases and must cover a wide range of potential pathogens, such as Streptococcus pneumoniae, including penicillin-resistant strains, Haemophilus influenzae and intracellular microorganisms. The objective of this double-blind, randomized, parallel group study was to compare the efficacy and safety of sparfloxacin (400 mg loading dose, followed by 200 mg o.d.) with that of oral amoxycillin-clavulanic acid (500/125 mg t.i.d.) or oral erythromycin (1 g b.i.d.), during 7-14 days in 808 patients with confirmed community-acquired pneumonia. The overall success rates for sparfloxacin (87%), amoxycillin-clavulanic acid (80%) and erythromycin (85%) were similar in evaluable patients, and the equivalence hypothesis used for the statistical analysis showed at least an equivalent efficacy for the three antibiotics tested. The analysis of microbiologically documented infections (40% of the patients) showed that overall success rates were similar for S. pneumoniae and H. influenzae infections. Treatment withdrawal was necessary in 3.5, 2.5 and 7.7% of the patients treated with sparfloxacin, amoxycillin-clavulanic acid and erythromycin, respectively. This study indicates that sparfloxacin was at least as effective as amoxycillin-clavulanic acid or erythromycin in the treatment of mild-to-moderate community-acquired pneumonia and that the adverse effects were similar in the three groups.

Abstract
In a prospective clinical trial the pre- and postoperative presence of S. aureus was examined in 130 patients undergoing nasal septal surgery. The patients were randomized into three groups. The first group received no perioperative antibiotics, the second group was given oral amoxicillin plus clavulanic acid, while the third group was treated with oral sulfamethoxazol and trimethoprim. A significant decrease in the incidence of S. aureus was observed in post-operative cultures, but the difference was not attributable to the antibiotic use. Overall, 18.9% of the S. aureus carriers harbored toxic shock syndrome toxin-1 positive strains. However, the decrease in the presence of S. aureus and the risk for toxic shock syndrome was not influenced by the antibiotics administered. These findings show that the routine use of oral prophylactic antibiotics for patients undergoing nasal surgery seems not indicated.

Abstract
Five hundred thirty-seven patients were enrolled in two independent, investigator-blinded, multicenter, randomized clinical trials comparing the clinical and bacteriologic efficacies and the safety of 5- or 10-day treatment with cefuroxime axetil with those of 10-day treatment with amoxicillin-clavulanate in the treatment of secondary bacterial infections of acute bronchitis. Patients received either 5 or 10 days of treatment (n = 177 in each group) with cefuroxime axetil at 250 mg twice daily or 10 days of treatment (n = 183) with amoxicillin-clavulanate at 500 mg three times daily. Patients in the cefuroxime axetil (5 days) group received placebo on days 6 to 10. Bacteriologic assessments were based on sputum specimen cultures obtained preceding and, when possible, following treatment. Organisms were isolated from the pretreatment sputum specimens of 242 of 537 (45%) patients, with the primary pathogens being Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis, Streptococcus pneumoniae, and Staphylococcus aureus (28, 25, 13, 9, and 8% of isolates, respectively). Pathogens were eradicated or presumed to be eradicated in 87% (52 of 60), 91% (53 of 58), and 86% (60 of 70) of bacteriologically evaluable patients treated with cefuroxime axetil (5 days), cefuroxime axetil (10 days), and amoxicillin-clavulanate, respectively. A satisfactory clinical outcome (cure or improvement) was achieved in 82% (107 of 130), 86% (117 of 136), and 83% (130 of 157) of the clinically evaluable patients treated with cefuroxime axetil (5 days), cefuroxime axetil (10 days), and amoxicillin-clavulanate, respectively. Treatment with amoxicillin-clavulanate was associated with a significantly higher incidence of drug-related adverse events than was treatment with cefuroxime axetil for either 5 or 10 days (P = 0.001), primarily reflecting a higher incidence of drug-related gastrointestinal adverse events (37 versus 19 and 15%, respectively; P < 0.001), particularly diarrhea and nausea. These results indicate that treatment with cefuroxime axetil at 250 mg twice daily for 5 days is as effective as treatment for 10 days with either the same dose of cefuroxime axetil or amoxicillin-clavulanate at 500 mg three times daily in patients with acute bronchitis. In addition, treatment with cefuroxime axetil for either 5 or 10 days is associated with significantly fewer gastrointestinal adverse events, particularly diarrhea and nausea, than is 10-day treatment with amoxicillin-clavulanate.

Abstract
HISTORY AND FINDINGS A 61-year-old woman fell ill with recurrent nausea, loss of appetite and tiredness. Five days later she noted increasing jaundice of skin and sclerae, pale stools and dark urine, and she developed itching over the whole body. Among biochemical tests alkaline phosphatase (537 U/l) and bilirubin (32.0 mg/dl) were markedly increased, while both GOT (102 U/l) and GPT (39 U/l) were only slightly elevated. Ultrasonography was normal and extrahepatic cholestasis appeared unlikely on endoscopic retrograde cholangiopancreatography. Cholestasis due to virus hepatitis was also excluded. It was only on repeated and direct questioning that the patient reported having taken three tablets daily of Augmentin (amoxicillin and clavulanic acid) for 12 days 5 weeks before the onset of symptoms. TREATMENT AND COURSE After symptomatic treatment with Colestyramine (4 g three times daily), ursodeoxycholic acid (250 mg twice daily) and the antihistaminic Clemastine (1 g two times daily) the severe pruritus decreased quickly and alkaline phosphatase concentration became normal. At follow-up examination 4 and 8 weeks later the laboratory tests were normal. CONCLUSIONS This report of Augmentin-induced cholestasis is not unique. It shows that previous drug intake must be carefully investigated in any case of cholestasis of unknown cause.

Abstract
Two independent, investigator-blinded, multicenter, randomized clinical trials, one of which included microbiologic evaluation of middle-ear fluid obtained by use of tympanocentesis, compared the efficacy and safety of two oral antibiotics, cefuroxime axetil suspension and amoxicillin/clavulanate suspension, in the treatment of children 3 months to 12 years old diagnosed with acute otitis media with effusion (AOME). Four hundred seventy-seven pediatric patients with signs and symptoms of AOME were enrolled at 20 centers and were randomly assigned to receive 10 days of treatment with either cefuroxime axetil suspension 30 mg/kg per day in two divided doses (n = 235) or amoxicillin/clavulanate suspension 40 mg/kg per day in three divided doses (n = 242). Patients were assessed for their response to treatment once during treatment (at 3 to 5 days) and twice after treatment (at 1 to 4 days and at 14 to 18 days). In the study that included tympanocentesis, bacteriologic assessments were based on middle-ear fluid cultures obtained pretreatment, and, when possible, posttreatment in patients with an unsatisfactory clinical outcome. Organisms were isolated from the pretreatment middle-ear fluid specimens of 120 (73%) of 164 patients undergoing tympanocentesis, with the primary pathogens being Streptococcus pneumoniae. Haemophilus influenzae, and Moraxella catarrhalis (27%, 24%, and 6% of isolates, respectively). Forty-four percent of the H influenzae isolates and 94% of the M catarrhalis isolates that were tested for beta-lactamase production were positive. A satisfactory clinical outcome (cure or improvement) was obtained in 70% of clinically assessable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (P = 0.40). With respect to the eradication of bacterial pathogens, in the study that included tympanocentesis a satisfactory outcome (cure or presumed cure) was obtained in 84% (32 of 38) and 95% (36 of 38) of bacteriologically assessable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (P = 0.26). Treatment with amoxicillin/clavulanate was associated with a significantly higher incidence of drug-related adverse events than was treatment with cefuroxime axetil (37% vs 16%; P < 0.001), primarily reflecting a higher incidence of drug-related gastrointestinal adverse events (34% vs 12%; P < 0.001), particularly diarrhea. Eight patients in the cefuroxime axetil group and 11 patients in the amoxicillin/clavulanate group withdrew from the studies because of drug-related adverse events. These results indicate that cefuroxime axetil suspension 15 mg/kg twice daily is as effective as amoxicillin/clavulanate suspension 13.3 mg/kg three times daily in the treatment of pediatric patients with AOME, but produces fewer gastrointestinal adverse events, particularly diarrhea.

Abstract
Two independent, investigator-blinded, multicenter, randomized clinical trials compared the clinical and bacteriologic efficacy and safety of two oral antibiotics, cefuroxime axetil and amoxicillin/clavulanate, in the treatment of patients with secondary bacterial infections of acute bronchitis (hereafter denoted acute bronchitis). Three hundred sixty patients with signs and symptoms of acute bronchitis were enrolled at 22 centers and were randomly assigned to receive 10 days of treatment with either cefuroxime axetil 250 mg twice daily (BID) (n= 177) or amoxicillin/clavulanate 500 mg three times daily (TID) (n = 183). Patients were assessed for both clinical and bacteriologic responses once during treatment (at 3 to 5 days) and twice after treatment (at 1 to 3 days and at 13 to 15 days). Bacteriologic assessments were based on sputum specimen cultures obtained before treatment and, when possible, after treatment. Organisms were isolated from the pretreatment sputum specimens of 162 (45%) of 360 patients, with the primary pathogens being Haemophilus influenzae, Haemophilus parainfluenzae, Streptococcus pneumoniae, Moraxella catarrhalis, and Staphylococcus aureus (28%, 25%, 11%, 9%, and 8% of isolates, respectively). Thirty-four percent of the H influenzae isolates and 94% of the M catarrhalis isolates that were tested for beta-lactamase production were positive. A satisfactory clinical outcome (cure or improvement) was achieved in 86% (117 of 136) and 83% (130 of 157) of the clinically assessable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (P = 0.45). With respect to the eradication of bacterial pathogens, a satisfactory outcome (cure, presumed care, or cure with colonization) was obtained in 91% (53 of 58) and 86% (60 of 70) of bacteriologically assessable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (P = 0.32). Treatment with amoxicillin/clavulanate was associated with a significantly higher incidence of drug-related adverse events than was treatment with cefuroxime axetil (39% vs 23%; P = 0.001), primarily reflecting a higher incidence of drug-related gastrointestinal adverse events (37% vs 15%; P < 0.001), particularly diarrhea and nausea. Four patients in the cefuroxime axetil group and eight patients in the amoxicillin/clavulanate group withdrew from the study because of drug-related adverse events. These results indicate that cefuroxime axetil 250 mg BID is as effective as amoxicillin/clavulanate 500 mg TID in the treatment of patients with acute bronchitis but produces fewer gastrointestinal adverse events, particularly diarrhea and nausea.

Abstract
Oral antibiotic therapy can alter the gastrointestinal microflora and result in troublesome gastrointestinal complaints. Patients who have experience with broad-spectrum antibiotics may be reluctant to start or to comply with antibiotic therapy due to the associated discomfort. In the field of otolaryngology, oral antibiotic therapy is commonplace, and patient intolerance of a particular antibiotic may result in compromise to a less effective choice. Yogurt, which contains Lactobacillus acidophilus, is often recommended by practitioners to help reduce the side effects of oral antibiotic therapy. We wanted to objectively evaluate the effect of orally administered L. acidophilus on the gastrointestinal side effects of oral broad-spectrum antibiotic therapy. Twenty-seven outpatients, 10 years of age or older, with ear, sinus, or throat infections, in whom amoxicillin/clavulanate was felt to be the antibiotic of choice, were randomly assigned to amoxicillin/clavulanate only, or amoxicillin/clavulanate and Lactobacillus treatment groups. Each patient was advised by the nursing staff to consume a well-balanced diet, and a detailed explanation of the medication schedule was given. A questionnaire was given to each patient at the conclusion of therapy. The data were analyzed using Spearman's rank-order correlations. Concomitant therapy of L. acidophilus with amoxicillin/clavulanate was associated with a significant decrease in patient complaints of gastrointestinal side effects and yeast superinfection. Almost all patients (89%) reported resolution of infection during the course of therapy. We believe that use of L. acidophilus is warranted in patients on broad-spectrum antibiotic therapy with gastrointestinal complaints.

Abstract
A 25-year old man suffered from acute pancreatitis and cholestatic acute hepatitis simultaneously after 4 weeks of an antibiotic treatment withdrawal (amoxicillin plus clavulanic acid) which was given for pharyngitis. Other potential etiological causes of both acute pancreatitis and liver disease, were excluded. The causal relationship between amoxicillin plus clavulanic acid and cholestatic hepatitis is well know, but no data has been reported regarding acute pancreatitis. The medical literature is reviewed and the mechanisms of toxicity are discussed.
