The side effect of anticancer agents such as nausea and vomiting frequently interrupt chemotherapy. To reduce these side effects, 5-hydroxytryptamine (5-HT3) receptor antagonist or metoclopramide is administered combined with steroid. In this study, we examined the effect of 5-HT3 receptor antagonist on the frequency of nausea and vomiting in a male cancer patient treated with/without steroid. This patient in his sixties had esophageal cancer (stage IV). He was administered nedaplatin 100 mg/day for 1 day and then 5-fluorouracil (5-FU) 750 mg/day for 5 days combined with radiotherapy (60 Gy) as one cycle of this chemotherapy. In the first cycle, 5-HT3 receptor antagonist was administered, and in the second, the antagonist was administered after treatment with steroid. The blood levels of total bilirubin, GOT, GPT, BUN, Cre, Na, K and Cl were stable normally during both cycles of the chemotherapy, indicating that the hepatopathy and nephropathy which cause nausea and vomiting did not occur in these periods. The frequency and period of the nausea and vomiting were one-third decreased, respectively, by the combination of 5-HT3 receptor antagonist and steroid.

HELLP syndrome belongs to the group of pathological disorders associated with pregnancy-induced hypertension and may accompany preeclampsia. The basic criteria for establishing the diagnosis are as follows: H--for hemolysis, EL--for elevated liver enzymes and LP--for low platelets. In this report the authors present the case of a 32 years old primipara admitted to the Obstetrics Clinic complaining of epigastric pain, nausea and vomiting. Medical history revealed previously diagnosed and treated reflux disease. In the 39th week of gestation epigastric pain manifested again, blood pressure was high (150/100) and on the basis of laboratory parameters HELLP syndrome was diagnosed (GPT 319 U/L, GOT 204 U/L, platelet 80 x 10(9)/L, antithrombin III 63.9%, D-dimer (+++)). With this case report, authors wished to point out the importance of early diagnosis and treatment of this rare, but having high percentage of perinatal mortality syndrome.

A late phase II clinical study (II) of a novel vinca alkaloid derivative KW-2307 (vinorelbine ditartrate) in advanced/recurrent breast cancer patients was performed at 22 institutions throughout Japan. An intravenous dose of KW-2307, 20 mg/m2, was administered once a week. Of the 60 patients enrolled in the study, 58 were eligible and 56 were evaluable. The response rate was 33.9% (19/56; 95% confidence interval: 21.8 to 47.8%) with one CR and 18 PRs. The response rate was as high as 37.0% (17/46; 95% confidence interval: 23.2 to 52.5%) when KW-2307 was used as a first-line chemotherapy for advanced/recurrent disease. The most common adverse event was myelosuppression including leukopenia in 96.4% (54/56) and neutropenia in 94.3% (50/53). Other events observed were increased GOT in 51.8% (29/56), increased GPT in 55.4% (31/56), LDH increased in 50.0% (27/54), serum total protein decrease in 39.3% (22/56), anorexia in 41.1% (23/56), nausea and vomiting in 66.1% (37/56), constipation in 30.4% (17/56), alopecia in 33.9% (19/56) and general fatigue in 46.4% (26/56). None of them were serious. This study demonstrated that KW-2307 was an effective and safe treatment for advanced/recurrent breast cancer patients.

In a randomized, double-blind, controlled trial, 546 patients with complicated skin and skin structure infections received tigecycline 100 mg/day (a 100-mg initial dose and then 50 mg intravenously twice daily) or the combination of vancomycin 2 g/day (1 g intravenously twice daily) and aztreonam 4 g/day (2 g intravenously twice daily) for up to 14 days. The primary end point was the clinical response in the clinical modified intent-to-treat (c-mITT) and clinically evaluable (CE) populations at the test-of-cure visit 12 to 92 days after the last dose. The microbiologic response at the test-of-cure visit was also assessed. Safety was assessed by physical examination, laboratory results, and adverse event reporting. Five hundred twenty patients were included in the c-mITT population (tigecycline group, n = 261; combination group, n = 259), and 436 were clinically evaluable (tigecycline group, n = 223; combination group, n = 213). The clinical responses in the tigecycline and the combination vancomycin and aztreonam groups were similar in the c-mITT population (84.3% versus 86.9%; difference, -2.6% [95% confidence interval, -9.0, 3.8]; P = 0.4755) and the CE population (89.7% versus 94.4%; difference, -4.7% [95% confidence interval, -10.2, 0.8]; P = 0.1015). Microbiologic eradication (documented or presumed) occurred in 84.8% of the patients receiving tigecycline and 93.2% of the patients receiving vancomycin and aztreonam (difference, -8.5 [95% confidence interval, -16.0, -1.0]; P = 0.0243). The numbers of patients reporting adverse events were similar in the two groups, with increased nausea and vomiting rates in the tigecycline group and an increased incidence of rash and increases in alanine aminotransferase and aspartate aminotransferase levels in the combination vancomycin and aztreonam group. Tigecycline was shown to be safe and effective for the treatment of complicated skin and skin structure infections.

EKB-569 is a potent, low molecular weight, selective, and irreversible inhibitor of epidermal growth factor receptor (EGFR) that is being developed as an anticancer agent. A phase 1, dose-escalation study was conducted in Japanese patients. EKB-569 was administered orally, once daily, in 28-day cycles, to patients with advanced-stage malignancies known to overexpress EGFR. Two patients with advanced non-small cell lung cancer with EGFR mutations and acquired gefitinib resistance from the phase 1 study are described in detail. Case #1 is a 63-year-old man with smoking history. He received treatment from 4 March 2004. Because he had no severe adverse events, a total of 10 courses of therapy were completed through December 16. Grade 2 skin rash and ALT elevation, and grade 1 diarrhea and nail changes developed. A chest CT scan on 4 August 2003 revealed multiple pulmonary metastases that had decreased in size. Case #2 is a 49-year-old woman with no smoking history. She received therapy from 9 February 2004. She received a total of five courses of the therapy until 22 June 2004. Grade 3 nausea and vomiting and grade 1 diarrhea and dry skin developed. A chest CT scan on March 3 revealed multiple pulmonary metastases that had decreased in size. A brain MRI on March 4 showed that multiple brain metastases also had decreased in size. Based on RECIST criteria, they had stable disease but radiographic tumor regression was observed.

The pharmacokinetics and toxicity profile of stampidine (STAMP, DDE-113, HI-113, N-[p-(4-bromophenyl)-2',3'-didehydro-3'-deoxy-5'-thymidylyl]-L-alanine methyl ester, CAS 217178-62-6) were studied in beagle dogs and feline immunodeficiency virus-infected domestic cats. Therapeutic plasma concentrations of STAMP 3-4 logs higher than its IC50 value can be achieved after its p.o. administration to dogs as well as cats at the 100 mg/kg nontoxic dose level. In accordance with its safety profile in rodent species, a 4- to 7-week STAMP treatment course with twice daily administration of hard gelatin capsules containing 25-100 mg/kg (50-200 mg/kg/ day) STAMP was very well-tolerated by dogs and cats at cumulative dose levels as high as 8.4 g/kg. Except for the sporadic occurrence of nausea and vomiting after its administration and elevation of serum ALT levels in some of the cats, STAMP therapy was not associated with any clinical or laboratory evidence of toxicity. No STAMP-related toxic lesions were found in any of the organs from STAMP-treated cats or dogs. These findings encourage the further development of stampidine for possible clinical use in HIV-infected persons.

Saw palmetto is a frequently used botanical agent in benign prostatic enlargement (BPH). Although it has been reported to cause cholestatic hepatitis and many medical conditions, Saw palmetto has not been implicated in acute pancreatitis. We report a case of a probable Saw palmetto induced acute hepatitis and pancreatitis. A 55-year-old reformed alcoholic, sober for greater than 15 years, presented with severe non-radiating epigastric pain associated with nausea and vomiting. His only significant comorbidity is BPH for which he intermittently took Saw palmetto for about four years. Physical examination revealed normal vital signs, tender epigastrium without guarding or rebound tenderness. Cullen and Gray Turner signs were negative. Complete blood count and basic metabolic profile were normal. Additional laboratory values include a serum amylase: 2,152 mmol/L, lipase: 39,346 mmol/L, serum triglyceride: 38 mmol/L, AST: 1265, ALT: 1232 and alkaline phosphatase was 185. Abdominal ultrasound and magnetic resonance cholangiography revealed sludge without stones. A hepatic indole diacetic acid scan was negative. Patient responded clinically and biochemically to withdrawal of Saw palmetto. Two similar episodes of improvements followed by recurrence were noted with discontinuations and reinstitution of Saw Palmetto. Simultaneous and sustained response of hepatitis and pancreatitis to Saw palmetto abstinence with reoccurrence on reinstitution strongly favors drug effect. "Natural" medicinal preparations are therefore not necessarily safe and the importance of detailed medication history (including "supplements") cannot be over emphasized.

We conducted a single institution phase II trial to evaluate the tolerability and effectiveness of therapy with arsenic trioxide (ATO) and ascorbic acid (AA) with temozolomide (TMZ) in patients with advanced melanoma. Planned enrollment was for 40 patients. Eligible patients were required to have metastatic melanoma with or without brain metastases, an ECOG performance status of 0-2, and adequate organ function. The primary endpoints were overall response rate and degree of grade 4 toxicity. ATO was administered as a loading dose at 0.25 mg/kg/day for 5 days during week 0, and then twice weekly at 0.35 mg/kg during an 8-week cycle. Each infusion of ATO was followed by an infusion of 1000 mg of AA. TMZ was given at the standard dose of 200 mg/m for 5 days during weeks 1 and 5 of each cycle. Eleven patients were enrolled with 10 evaluable for response, five with central nervous system disease. No responses were seen among the first 10 patients and on the basis of a predetermined stopping rule, the trial was terminated. Common grade 1 and 2 side effects included nausea and vomiting (10), fatigue (six), edema (six), rash (six), and elevated AST or ALT (six). Grade 3 and 4 side effects included nausea and vomiting (three), elevated AST or ALT (two), seizure (one), and renal failure (one). This is the first trial combining ATO with chemotherapy in a solid tumor. ATO and AA were administered in the outpatient setting with TMZ in 11 patients with an acceptable side effect profile. No responses were seen in the first 10 evaluable patients leading to early closure of the study. Further studies using ATO and AA with TMZ with this dosing schedule in advanced melanoma are not warranted.

Tigecycline exhibits potent in vitro activity against many community-acquired pneumonia (CAP) pathogens, including antibiotic-resistant ones. Its spectrum of activity and ability to penetrate lung tissue suggest it may be effective for hospitalized CAP patients. Hospitalized CAP patients (n=418) were randomized to receive intravenous (i.v.) tigecycline or levofloxacin. Patients could be switched to oral levofloxacin after receiving 6 or more doses of i.v. study medication. Therapy duration was 7 to 14 days. Coprimary efficacy end points were clinical responses in the clinically evaluable (CE: tigecycline, n=138; levofloxacin, n=156) and clinical modified intent-to-treat (c-mITT: tigecycline, n=191; levofloxacin, n=203) populations at test-of-cure (TOC). Safety was assessed in the mITT population (tigecycline, n=208; levofloxacin, n=210). Cure rates in tigecycline and levofloxacin groups were comparable in CE (90.6% versus 87.2%, respectively) and c-mITT (78% versus 77.8%, respectively) populations at TOC. Nausea and vomiting occurred in significantly more tigecycline-treated patients; elevated alanine aminotransferase and aspartate aminotransferase levels were reported in significantly more levofloxacin-treated patients. There were no significant differences in hospital length of stay, median duration of i.v. or oral antibiotic treatments, hospital readmissions, or number of patients switched to oral levofloxacin. Tigecycline was safe, effective, and noninferior to levofloxacin in hospitalized patients with CAP.

In a randomized, double-blind, multicenter, multinational, controlled trial, 546 patients with complicated skin and skin structure infections received tigecycline 100 mg/day (a 100-mg initial dose and then 50 mg intravenously twice daily) or the combination of vancomycin 2 g/day (1 g intravenously twice daily) and aztreonam 4 g/day (2 g intravenously twice daily) for up to 14 days. Three hundred eighty-five (385) were from Europe. The primary endpoint was the clinical response in the clinical modified intent-to-treat (c-mITT) and clinically evaluable populations at the test-of-cure visit 12 to 92 days after the last dose. The microbiologic response at the test-of-cure visit was also assessed. Safety was assessed by physical examination, laboratory results and adverse event reporting. Of the patients enrolled in Europe, 376 patients were included in the c-mITT population (tigecycline group, n = 189; vancomycin/aztreonam group, n = 187), and 326 were clinically evaluable (tigecycline group, n = 167; vancomycin/aztreonam group, n = 159). The clinical responses in the tigecycline and the vancomycin/aztreonam groups in the clinically evaluable population were 89.8% versus 95.0%. Microbiologic eradication (documented or presumed) occurred in 84.8% of the European patients receiving tigecycline and 93.2% of the European patients receiving vancomycin/aztreonam. The number of European patients reporting adverse events was similar in the two groups, with increased nausea and vomiting rates in the tigecycline group and an increased incidence of rash and increases in alanine aminotransferase and aspartate aminotransferase levels in the vancomycin/aztreonam group. Current data support findings from the overall results in the Phase 3 study and suggest that tigecycline is safe and effective for the treatment of complicated skin and skin structure infections.
