Ifosfamide side effects infection
Eligibility Between January 1998 and May 2003, 48 patients with advanced metastatic GCT were accrued to this prospective trial approved by the institutional review board at Memorial Sloan-Kettering Cancer Center New York, NY ; . All patients had histologically confirmed GCT and assessable disease; clinical resistance to cisplatin established by failure to achieve a durable CR to a cisplatin-based regimen; and one or more unfavorable prognostic features for treatment with conventional-dose salvage therapy. Unfavorable prognostic factors for achieving a CR to conventional-dose salvage therapy included: extragonadal primary site; progressive disease after an IR to first-line therapy; and poor or lack of response to prior treatment with cisplatin plus ifosfamide conventional-dose therapy. Progressive GCT was documented by increasing values of serum alpha-fetoprotein AFP ; and or human chorionic gonadotropin HCG ; . In the absence of elevated serum tumor marker s ; , a biopsy was performed to document the presence of active GCT and to exclude teratoma ; . The intent of this trial was to restrict eligibility to patients with prior therapy of six or more cycles of cisplatin combination therapy group A ; and, in this group of patients, to increase the carboplatin target AUC in the manner of a phase I trial. Once the maximum-tolerated dose MTD ; was established, additional patients would be treated at the MTD. Because this program was relatively well tolerated and to accumulate additional pharmacologic data, more heavily pretreated patients were enrolled at a fixed dose level of carboplatin AUC of 21 mg mL ; min group B ; . Additional eligibility criteria included WBC count 3, 000 L, platelets 100, 000 L, and creatinine clearance more than 50 mL min. Exclusionary.

Bone with metastases at diagnosis were enrolled onto this trial. A light microscopic appearance consistent with Ewing's sarcoma, PNET of bone, or any other primitive sarcoma of bone was required for enrollment. Representative slides were reviewed centrally by one of us P.S.D. ; but this review was not required for study enrollment. This trial accrued patients from 1988 to 1992. The patients were assigned randomly to regimen A standard therapy ; or regimen B standard therapy plus combined ifosfamide and etoposide ; . To participate, patients or their guardians gave written informed consent according to institutional and US National Cancer Institute guidelines, and the protocol was reviewed and approved by institutional human subjects review boards. The protocol review and implementation were in compliance with the Declaration of Helsinki. Before enrollment, every patient was assessed for the presence of metastatic disease. This evaluation included a chest x-ray and computed tomography of the lung, a bone scan, a bone marrow biopsy, and a bone marrow aspiration. Patients were randomly assigned to receive either regimen A or B, as described subsequently. The randomization was stratified according to the presence of metastatic disease. The protocol schema is shown in Figure 1. Regimen A consisted of vincristine 2 mg m2, doxorubicin 75 mg m2, cyclophosphamide 1, 200 mg m2, and dactinomycin 1.25 mg m2, with each course containing doxorubicin the first five courses ; or dactinomycin subsequent courses ; . Regimen B consisted of those four agents alternating every 3 weeks with combined ifosfamide 1, 800 mg m2 d for 5 days and etoposide 100 mg m2 d for 5 days. Therapy for both arms was planned to last 51 weeks.5 Of the four agents in common to the two regimens, only the planned dose of doxorubicin was the same. Seventeen courses of therapy were to be administered. If the patient did not have treatment delays, this would be accomplished in 51 weeks. Local control of the primary and metastatic disease was recommended at week 9. Surgery of the primary site was recommended if feasible. Patients were to receive radiation therapy to all sites of metastatic disease. This was to be administered concurrently with radiation therapy to the primary tumor site, if it was to be given. For patients who received radiotherapy only to the primary tumor site, the initial tumor volume soft tissue and osseous extent of tumor ; with a 3-cm margin was treated to 45 Gy. That was followed by reduction in treatment volume to the postchemotherapy, preradiotherapy tumor extent for 10.80 Gy.

Ifosfamide is a white crystalline powder that is soluble in water and iloprost.
Gemcitabine and cisplatin has demonstrated impressive activity in a pilot study [41]. Preliminary data using frontline combinations with platinum, paclitaxel, and gemcitabine have also been presented [42], and GOG is conducting a front-line phase I trial of gemcitabine in combination with carboplatin and paclitaxel to define a feasible regimen for phase III evaluation. Other nonplatinum combinations are also under development, and may show promise as second-line therapy. However, at the present time, single-agent therapy, or possibly a conservative combination with cisplatin, due to the risk of cumulative nonhematologic toxicity, are the most appropriate options for patients with recurrent disease. Ifosfamide Several clinical trials have demonstrated ifosfamide to be an active agent in ovarian cancer patients after initial platinum-based therapy 10%-20% objective response rate ; [4345]. As an older agent, most of the experience with ifosfamide has been in patients previously treated with a combination of platinum and cyclophosphamide, prior to the incorporation of paclitaxel. It has been suggested that the current second-line activity of ifosfamide might be enhanced as a consequence of a reduction in the use of cyclophosphamide during initial therapy of ovarian cancer. However, a recently reported trial of single-agent ifosfamide in patients refractory to both platinum and paclitaxel has revealed an objective response rate of only 15%, similar to that achieved in patients previously treated with cyclophosphamide [46]. Ifosfamide has a number of important toxicities to be considered in the ovarian cancer population, including neutropenia, renal dysfunction, injury to the urothelium hemorrhagic cystitis ; , and reversible central nervous system dysfunction. Risk for these toxicities is increased in elderly patients with renal dysfunction and low serum albumin, which are common findings in recurrent ovarian cancer. The drug also has the disadvantage of being administered over multiple days, or requiring a 24-h intravenous infusion. Vinorelbine Vinorelbine has been explored in the treatment of ovarian cancer when administered by one of several schedules, including 25 to 30 mg m2 week [47, 48], and 20 mg m2 day for three days repeated on an every-three-week schedule [49]. Objective responses have been observed in approximately 15% to 30% of the patients defined in the trials as having platinum resistant or refractory disease. The major toxicities of vinorelbine are neutropenia and anemia. In addition, the drug can result in a worsening of a pre-existing peripheral neuropathy from the initial platinum paclitaxel treatment program.

The median follow-up was 58 months; 4-year distant recurrence survival rates for ifosfamide chemotherapy vs none were 74% vs 46% p ; , and disease-specific survival rates were 88% vs 67% p and indinavir.
Clinical studies, as the glucose concentration at which glucose effectiveness is assessed frequently differs between groups and after various interventions. The present experiments were, therefore, undertaken to determine whether short term restoration of euglycemia by means of an overnight insulin infusion improves the ability of glucose to stimulate its own uptake and to suppress its own release in subjects with type 2 diabetes mellitus. To do so, we measured glucose effectiveness in diabetic individuals after either overnight hyperglycemia i.e. glucose concentrations permitted to remain at ambient levels ; or overnight euglycemia. On the hyperglycemic study day, the glucose concentration was acutely lowered the following morning by means of a variable insulin infusion so that glucose effectiveness was assessed in all subjects in the presence of comparable baseline glucose and insulin concentrations. We report that in contrast to its effects on insulin action 19 ; , overnight restoration of euglycemia does not alter glucose effectiveness in subjects with type 2 diabetes.

Because there has been no agreement as to the criteria that should be used to gauge an increase in heart rate before ischemic episodes. Recent data from our laboratory suggest that there are at least two separate populations of ambulatory ischemic episodes distinguished by the presence or absence of an increase in heart rate .5 beats per minute during the 30-minute period preceding the onset of ST-segment depression.25 Analysis of the heart rate patterns in the present study and infliximab.

Man and said unto him: art thou the man that spakest unto my wife? And he said, yee. Then Manoah said, now when thy saying is come to pass: what shall be the manner of the child, and what shall he do? And the Angel of the Lord said unto Manoah: thy wife must abstain from all that I said unto her: she may eat of nothing that cometh of the vine tree, nor drink wine or strong drink, nor eat any unclean thing: But must observe all that I bade her. Then said Manoah unto the Angel of the Lord, grant us to tarry until we have made ready a kid and have set it before thee. And the angel of the Lord said unto Manoah: though thou make me abide, I will not eat of thy meat. And moreover, if thou wilt prepare a burntoffering, that thou must offer unto the Lord. For Manoah knew not that it was an angel of the Lord. And Manoah said unto the angel of the Lord: what is thy name, that when thy saying is come to pass, we may do thee some worship? And the angel of the Lord said unto him: why askest thou after my name? when it is marvelous. And Manoah took a Kid with a meat offering and offered it upon a rock unto the Lord. And the angel did wonderfully, Manoah and his wife looking upon. For when the flame came up out of the altar, the angel of the Lord ascended up in the flame of the altar. And Manoah and his wife looked upon and fell flat on their faces unto the ground: But the angel of the Lord did no more appear unto Manoah and his wife. And then Manoah knew that it was an angel of the Lord: and said unto his wife: we shall surely die, because we have seen God. But his wife said unto him: If the Lord would kill us, he would not have received a burntoffering and a meatoffering of our hands, neither would he have showed us all these things, nor would have told us as he hath of things to come. And the wife bare a son, and called his name Samson. And the lad grew, and the and intal.

Vinca alkaloids. Vincristine use has been associated with a number of cases of hyperinfection 54, 94, 118 ; . Although most of these patients also received glucocorticoids, it has been proposed that vinca alkaloids exert a toxic effect on myenteric neurons, decreasing intestinal motility and increasing the amount of time that rhabdtiform larvae have to molt to invasive filariform larvae. The first reported case of hyperinfection complicating lymphoma was a 63-year-old man with Hodgkin's who received vinblastin sulfate but not glucocorticoids ; and developed fecal impaction shortly thereafter 95 ; . Two reports describe S. stercoralis in patients who received vincristine but not glucocorticoids: one was a case of hyperinfection that occurred in a patient with high endogenous adrenocorticotropin levels due to small cell lung carcinoma 21 the other was a case not of hyperinfection but of eosinophilic gastroenteritis and recurrent eosinophilia 99 ; . Therefore, evidence for vinca alkaloids themselves causing hyperinfection remains anecdotal. Cyclosporine. Given its widespread use, the absence of an association of cyclosporine with S. stercoralis hyperinfection is striking. In fact, one notes a decline in case reports of hyperinfection occurring in renal transplant recipients after about 1990, when cyclosporine became a standard part of the posttransplant regimen. There is some experimental evidence that cyclosporin A may actually have an anthelmintic effect on S. stercoralis 105 ; . The one case of S. stercoralis hyperinfection in a patient on cyclosporine occurred after the drug was withdrawn and cyclosporine levels were declining 87 ; . Resuming cyclosporine therapy alone was not sufficient to cure the hyperinfection, but the patient did well once treated with thiabendazole. Other immunosuppressive drugs. Numerous other drugs have contributed to immunosuppressive states associated with hyperinfection, including azathioprine 129 ; , cyclophosphamide 29, 99, 118 ; , antithymocyte globulin 74, 131 ; , anti-CD3 87 ; , chlorambucil 94 ; , 6-mercaptopurine 94 ; , methotrexate 99, 118 ; , bleomycin 118 ; , adriamycin 99 ; , doxorubicin 104, 118 ; , daunorubicin 23 ; , ifosfamide 118 ; , melphalan 104 ; , carmustine 104 ; , VP16 96, 118 ; , and mitoxantrone 118 ; , as well as total body irradiation 95 ; . In all of these cases, glucocorticoids were administered contemporaneously. Attributing hyperinfection to any of these other drugs alone is therefore difficult. Hematologic Malignancies Glucocorticoids are employed in the treatment of many hematologic malignancies, but there are case reports of S. stercoralis hyperinfection developing in such patients prior to therapy 1, 132 ; . In one case of small intestinal lymphoma, in which S. stercoralis larvae were seen in large numbers in the lymphomatous tissue itself; the authors suggest that chronic parasiteinduced inflammation may have contributed to the development of the lymphoma in the first place 16 ; . Kidney Transplants The majority of cases of hyperinfection that have occurred following organ transplant have occurred following renal transplant, and most of these cases seem to have been precipitated by increased glucocorticoid doses in response to rejection 9.

Mesna is used to protect a patient from the urothelial toxic effects of oxazaphosphorines ifosfamide or cyclophosphamide ; . The duration of treatment is equal to that of the oxazaphosphorine plus the time taken for the concentration of oxazaphosphorine metabolites to fall to nontoxic levels. The oral dose of mesna is 40% w w of the oxazaphosphorine dose, rounded down to the nearest whole tablet. A dose is sometimes prescribed equivalent to half a tablet, i.e. 200 mg, and although the tablet can be halved, it has such a good safety profile, that the normal minimum dose is 400 mg.1 Mesna regimens vary according to the protocols used in chemotherapy. The following examples are as listed in the Summary of Product Characteristics.
