A 49 years-old man presented with dry cough, low grade fever, and abnormal shadow on a chest X-ray. He had suffered from follicular lymphoma of the liver 5 years previously. He received irradiation therapy in combination with chemotherapy for approximately three years and had been in complete remission. Physical and radiological examination revealed pleural effusion and softly dense masses in the right lung. The laboratory data were within normal limits. He was diagnosed as having lymphomatoid granulomatosis (LYG) by open lung biopsy. The lung lesion was mainly infiltrated with T cells. The patient received prednisolone and the lung lesions disappeared. However , when a lung mass was noted two months later , he started to receive combination chemotherapy consisting of cyclophosphamide , adriamycin , vincristine , and prednisolone every three months . He has not shown relapse of LYG so far. To investigate the association between the preceding follicular lymphoma and subsequent LYG at this time, DNA analysis using the PCR technique was carried out. The LYG lesion did not show a rearranged band for the JH probe, while the paraffin-embedded specimen of the preceding follicular lymphoma had shown rearranged band for the JH band. Southern blot analysis of the LYG lesion, showed no rearrangement for TCR beta, gamma or JH probe. These findings indicate that the LYG was different from the preceding follicular lymphoma in terms of origin.

] | [] | The role of beta-blockade therapy for ventricular tachycardia induced with isoproterenol: a prospective analysis. Isoproterenol is sometimes required for ventricular tachycardia (VT) induction. However, the role of beta-blockade for treatment of such VT has not been critically assessed. The use of beta-blockade was evaluated prospectively in 14 consecutive patients who required isoproterenol 2.4 +/- 1.3 (+/- S.D.) micrograms/min to induce sustained monomorphic VT (greater than 30 seconds, or requiring termination due to hemodynamic collapse) after a negative baseline study. The VT mechanisms were enhanced automaticity (group A, six patients), triggered automaticity (group B, three patients), and reentry (group C, five patients). Groups A and B had serial intravenous electropharmacologic tests with propranolol alone (0.2 mg/kg), verapamil alone (0.15 mg/kg), and propranolol plus verapamil, and group C had serial tests with propranolol alone, procainamide or quinidine (class Ia drug) alone, and propranolol plus a class Ia drug until VT could no longer be induced. All six patients in group A responded to propranolol alone. In group B, one patient responded to verapamil alone, and two patients responded to propranolol plus verapamil. In group C, three patients responded to propranolol alone, one patient responded to a class Ia drug alone, and one patient responded to propranolol plus a class Ia drug. During a follow-up of 7 to 37 (17.9 +/- 10.7) (+/- S.D.) months, VT has not recurred in any patient. Three patients treated initially with propranolol alone have required substitution of amiodarone due to refractory congestive heart failure .

The specific mechanism of cetuximab endocytosis and its influence on cetuximab uptake, biodistribution and efficacy still remain elusive. Recently, statins have been reported to synergize with EGFR-targeting agents. Our prior work established that nystatin, a cholesterol-sequestering antifungal drug, facilitates endocytosis via the clathrin-dependent pathway. This study aimed to investigate whether nystatin regulates the uptake and efficacy of cetuximab and cetuximab-based antibody-drug conjugates (cetuximab-ADCs). In vitro and in vivo efficacies of nystatin on the uptake and activity of cetuximab/cetuximab-ADCs were studied in multiple human carcinoma cell lines and xenograft models, respectively. We identified that cholesterol sequestration by nystatin enhanced cetuximab internalization in EGFR-positive carcinoma cells by regulating EGFR trafficking/turnover and facilitating a switch from lipid rafts to clathrin-mediated endocytosis. Combination treatment with cetuximab and nystatin selectively increased cetuximab uptake by tumor tissues , translating into potentiated antitumor efficacy of cetuximab in vivo ( A431 and A549 tumors ) . Nystatin-enhanced internalization of cetuximab further improved the uptake and potency of cetuximab-doxorubicin and cetuximab-methotrexate conjugates in EGFR-positive cetuximab-resistant tumors. Combination therapy with nystatin plus either cetuximab or cetuximab-ADC further prolonged animal survival and significantly suppressed tumor growth, as compared with single-agent cetuximab or cetuximab-ADC. In summary, our results identify a novel mechanism whereby cholesterol sequestration enhances the uptake of EGFR-targeting mAb and ADCs, therefore providing preclinical proof-of-concept that combination with nystatin can potentiate the delivery and efficacy of these EGFR-targeted agents. | null | ### Instruction:

The patients were treated with a combination of CDCA 750 mg daily and an increasing dose of simvastatin from 10 mg to 40 mg daily for a period of 6 months. We found a significant effect of this combination therapy compared with CDCA alone in terms of decreasing the serum cholestanol and LDL cholesterol levels, particularly with a daily dose of 40 mg simvastatin. The mean cholestanol level decreased from 9.27 micromol/L (baseline) to 6.69 micromol/L (40 mg simvastatin), while the mean LDL cholesterol level decreased from 5.08 mmol/L (baseline) to 3.04 mmol/L (40 mg simvastatin). No side effects were reported, and there were no effects on the clinical condition, cerebral magnetic resonance imaging (MRI), visual evoked potentials, and electroencephalographic features. We conclude that a combination of 750 mg CDCA and 40 mg simvastatin daily is effective to further reduce serum cholestanol, LDL cholesterol, and lathosterol in adult CTX patients treated with long-term CDCA.

Aromatase inhibitors (AI's) are increasingly being incorporated in the treatment strategy for hormone receptor positive breast cancer either alone or in combination with chemotherapy, biologics in both the adjuvant and metastatic setting [1]. They markedly suppress plasma estrogen levels by inhibiting or inactivating aromatase, the enzyme responsible for the synthesis of estrogens from androgenic substrates [1]. Currently, the three selective aromatase inhibitors that are available are anastrozole, letrozole and exemestane which reduce circulating estrogen to 1 to 10% of pretreatment levels [2]. For advanced breast cancer, aromatase inhibitors appear to be at a minimum, equivalent and perhaps even better than tamoxifen in the first line setting [3, 4]. In primary breast cancer, adjuvant therapy with anastrozole or letrozole appears to be superior to tamoxifen in reducing the risk of relapse [5, 6]. Common adverse effects associated with AI's include arthralgias (21%), myalgias (12%), other musculoskeletal disorders (28%) and an up to 60% increased risk of bone fracture [7, 8]. However , anastrozole , exemestane and letrozole are associated with significantly fewer endometrial cancers , as well as venous and arterial vascular events , when compared with tamoxifen [ 9 , 10 ] .

The long-term clinical outcome of pediatric intracranial epepdymoma is poor with a high rate of recurrence. One of the main reasons for this poor outcome is the tumor's inherent resistance to chemotherapy. Signal transducer and activator of transcription 3 (STAT3) is overactive in many human cancers, and inhibition of STAT3 signaling is an emerging area of interest in oncology. In this study, the possibility of STAT3 inhibition as a treatment was investigated in pediatric intracranial ependymoma tissues and cell lines. STAT3 activation status was checked in ependymoma tissues. The responses to conventional chemotherapeutic agents and a STAT3 inhibitor WP1066 in primarily cultured ependymoma cells were measured by cell viability assay. Apoptosis assays were conducted to reveal the cytotoxic mechanism of applied agents. Knockdown of STAT3 was tried to confirm the effects of STAT3 inhibition in ependymoma cells. High levels of phospho-STAT3 (p-STAT3) expression were observed in ependymoma tissue, especially in the anaplastic histology group. There was no cytotoxic effect of cisplatin , ifosfamide , and etoposide . Both brain tumor-initiating cells (BTICs) and bulk tumor cells (BCs) showed considerably decreased viability after WP1066 treatment. However, BTICs had fewer responses than BCs. No additive or synergistic effect was observed for combination therapy of WP1066 and cisplatin. WP1066 effectively abrogated p-STAT3 expression. An increased apoptosis and decreased Survivin expression were observed after WP1066 treatment. Knockdown of STAT3 also decreased cell survival, supporting the critical role of STAT3 in sustaining ependymoma cells.

Topotecan dosing based on simultaneous drug monitoring and pharmacokinetic analysis can yield more accurate and precise estimation of the topotecan systemic exposure than that attainable with the fixed dosing approach. Therefore, a combined approach could provide a tool assisting the clinicians in individualization of the topotecan dosing. The aim of the study was to estimate the topotecan exposure in pediatric patients with acute myeloid leukemia (AML) based on the plasma concentration-time data and using the pharmacokinetic analysis. The primary goal was achieve the correct estimation of the target plasma area against the topotecan concentration-time curve ( AUC ) in a 5 day course of cladribine followed by monitored topotecan in pediatric patients with recurrent/refractory AML . A sensitive and selective reversed-phase liquid chromatographic-mass spectrometry (LC-MS) assay was developed to quantify total topotecan in the human plasma samples. This method, with its lower quantification limit of 1 ng/ml, was validated over a linear range of 1-150 ng/ml. Under the proposed approach, the topotecan dosing was selected so as to achieve the final AUC value of 140±20 ng/ml h. The presented analytical and pharmacokinetic data demonstrate that the proposed approach can be a practical, useful, efficient, and accurate tool for individualizing the topotecan dosing in children with AML. | null | ### Instruction:

Topotecan exposure estimation in pediatric acute myeloid leukemia supported by LC-MS-based drug monitoring and pharmacokinetic analysis. Individualization of the topotecan dosing can reduce inter-patient variability, toxicity, and at the same time increases chemotherapy efficacy.

] | [] | Brodalumab for the Treatment of Moderate-to-Severe Plaque Psoriasis: An Evidence Review Group Evaluation of a NICE Single Technology Appraisal. As part of the National Institute for Health and Care Excellence single technology appraisal process, brodalumab was assessed to determine the clinical and cost effectiveness of its use in the treatment of moderate-to-severe plaque psoriasis. The Centre for Reviews and Dissemination and the Centre for Health Economics Technology Assessment Group at the University of York were commissioned to act as the independent Evidence Review Group. This article provides a summary of the Evidence Review Group's review of the company's submission, the Evidence Review Group report and the National Institute for Health and Care Excellence Appraisal Committee's subsequent guidance issued in March 2018. The main clinical effectiveness data were derived from three well-conducted, multicentre, double-blind randomised controlled trials. The trials demonstrated that brodalumab statistically significantly reduced the severity of psoriasis and its impact on health-related quality of life, compared with placebo, at 12 weeks. In comparison with ustekinumab, statistically significantly more patients taking brodalumab had reduced psoriasis severity at 12 weeks. Psoriasis severity and quality of life also appeared improved at 52 weeks, although statistical significance was not assessed. Withdrawal rates were comparable to drug survival rates of other biological therapies and rates of adverse events were similar between brodalumab and ustekinumab . A network meta-analysis was presented, comparing brodalumab with other therapies available at the same point in the treatment pathway (i.e. in patients for whom standard systemic therapy or phototherapy is inadequately effective, not tolerated or contraindicated). The network meta-analysis ranked treatments in order of effectiveness, in terms of achieving different levels of Psoriasis Area and Severity Index response. The results indicated that brodalumab had a similar probability of response to ixekizumab, secukinumab and infliximab and a higher probability of response than ustekinumab, adalimumab, etanercept, apremilast, dimethyl fumarate and placebo. The company's economic model compared nine treatment sequences that included three lines of active therapy, consisting of brodalumab and other comparators recommended by the National Institute for Health and Care Excellence, followed by best supportive care. The sequence with brodalumab in the first-line position dominated sequences that started with adalimumab, infliximab, secukinumab and ustekinumab. The incremental cost-effectiveness ratio of the brodalumab sequence compared to less effective and non-dominated sequences ranged from £7145 (vs. the etanercept sequence) to £13,353 (vs. the dimethyl fumarate sequence) per quality-adjusted life-year gained. The incremental cost-effectiveness ratio for the more costly and effective ixekizumab sequence was £894,010 per quality-adjusted life-year gained compared to the brodalumab sequence. At a threshold of £20,000 per quality-adjusted life-year gained, the brodalumab sequence had the highest probability of being cost effective (96%). The main limitation of the company's economic model was the restrictive nature of the sequences compared. Twelve separate scenarios based on key uncertainties were explored by the Evidence Review Group. The only scenarios where brodalumab was ranked lower than first were not considered to be more appropriate or plausible than the assumptions or scenarios included in the company's base case. The treatment rankings identified in the Evidence Review Group's alternative base case were identical to those derived from the company's base case model. At the first National Institute for Health and Care Excellence Appraisal Committee meeting, the Committee concluded that brodalumab appears to be as effective as other anti-interleukin-17 agents and is cost effective, based on the discount agreed in the patient access scheme. Brodalumab is recommended as an option for treating adults with severe plaque psoriasis (defined by a total Psoriasis Area and Severity Index score of 10 or more and a Dermatology Life Quality Index score of more than 10) who have not responded to other systemic non-biological therapies. Brodalumab should be stopped at 12 weeks if the psoriasis has not responded adequately. | null | ### Instruction:

We examined the feasibility and safety of using paclitaxel and trastuzumab as maintenance therapy after high-dose chemotherapy ( HDC ) with autologous hematopoietic stem cell transplantation ( AHST ) for patients with HER2-positive metastatic breast cancer . Ten patients (9 women and 1 man) were enrolled in the study. The median age was 46.5 years (range, 27-65 years). The median follow-up time was 1003 days (range, 216-2526 days). All patients had metastatic disease, but 2 had only bone metastasis. One patient had complete response, 6 had partial response and 3 had stable disease to the standard-dose chemotherapy prior to transplantation. The conditioning regimen consisted of cyclophosphamide, carmustine, and thiotepa. After AHST, patients received weekly paclitaxel for 12 doses and trastuzumab every 3 weeks for 1 year as maintenance therapy. All patients experienced successful engraftment. The only grade 4 toxic effects observed were leukopenia and thrombocytopenia. The most common grade 3 toxic effect was neutropenic fever. No treatment-related deaths were observed. The median progression-free survival time was 441 days, and the median overall survival time was 955 days. Two patients died in accidents while their disease remained in remission. Five patients died with disease progression. At the time of this report, 3 patients are alive with stable disease, 1 of whom has remained free of disease progression for 2526 days since transplantation.

The conditioning regimen consisted of cyclophosphamide, carmustine, and thiotepa. After AHST, patients received weekly paclitaxel for 12 doses and trastuzumab every 3 weeks for 1 year as maintenance therapy. All patients experienced successful engraftment. The only grade 4 toxic effects observed were leukopenia and thrombocytopenia. The most common grade 3 toxic effect was neutropenic fever. No treatment-related deaths were observed. The median progression-free survival time was 441 days, and the median overall survival time was 955 days. Two patients died in accidents while their disease remained in remission. Five patients died with disease progression. At the time of this report, 3 patients are alive with stable disease, 1 of whom has remained free of disease progression for 2526 days since transplantation. Our findings indicate that paclitaxel plus trastuzumab as maintenance therapy after HDC with AHST for patients with HER2-positive metastatic breast cancer not only is feasible and safe but also results in survival outcomes similar to historical results.
### Response:
paclitaxel, trastuzumab

Chemotherapy is the initial treatment of choice for patients with a negative estrogen receptor status, as well as for those with a positive estrogen receptor status who have failed to respond to endocrine treatment. Patients who fail on first-line chemotherapy become candidates for second-line salvage chemotherapy; the outlook for these patients is poor, and new active agents continue to be sought. docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) is a semisynthetic taxoid that is an inhibitor of microtubule depolymerization. This new anticancer agent has been studied in an extensive phase II clinical trial program involving 162 patients with second-line metastatic breast cancer, 134 of whom were anthracycline resistant. Doses of 100 mg/m2 of docetaxel, administered over 1 hour every 3 weeks, produced an overall response rate of 50% (range, 41% to 58%) in 129 evaluable patients, with a median duration of 6 months (range, 2 to 17 months). The response rates achieved to date with docetaxel in anthracycline-resistant patients compare favorably with those produced by the best monotherapies currently available, and are equivalent to those achieved with current combination chemotherapy options. docetaxel also was found to be highly effective in patients with a poor prognosis, having metastases in three or more organs (53%), and/or visceral sites of disease (47%). Furthermore , the overall response rate for docetaxel in the intent-to-treat population ( 42.5 % ) is superior to the response rate of either doxorubicin as second-line therapy ( 29.3 % ) or paclitaxel ( Taxol ; Bristol-Myers Squibb Oncology , Princeton , NJ ) when used as first- or second-line therapy ( 29 % ) in metastatic disease .

] | [] | The effects of intravesical lidocaine on bladder dynamics of children with myelomeningocele. Other studies have suggested that intravesical lidocaine may temporarily improve bladder dynamics but details of these effects and their application to children have not been examined. We evaluated the effects of intravesical lidocaine on bladder urodynamics of children with myelomeningocele and tried to correlate these effects with subsequent clinical response to oral oxybutynin. ### Materials And Methods Charts of children with myelomeningocele who had undergone urodynamic examinations from 1992 to 1998 were reviewed retrospectively. In children with uninhibited contractions or poor compliance 150 to 300 mg. lidocaine were instilled for 8 minutes and cystometry was repeated. Changes in bladder capacity and compliance, number of uninhibited contractions and bladder volume at which pressure of 40 cm. H2O was reached were recorded before and after the lidocaine instillation. Clinical response to subsequent treatment with oral oxybutynin was assessed from chart review. ### results A total of 48 urodynamic studies in 22 girls and 20 boys with a mean age plus or minus standard deviation of 8.3 +/- 5.7 years and myelomeningocele were evaluable. After instillation of lidocaine, urodynamics showed increased bladder capacity in 70.8% of studies (34 of 48), with an average increase in volume of 66% (p <0.05). No change or decreased bladder capacity occurred in 29.2% of studies. Bladder compliance improved in 61.7% of the studies (29 of 47, p <0.05) and worsened in 38.3%. Bladder volume at which the pressure of 40 cm. H2O was reached increased in 77.8% of studies (14 of 18, p <0.05). After lidocaine the number of uninhibited contractions decreased by 3.2 in 56.8% of studies (21 of 37, p <0.05). Correlation of lidocaine induced changes in bladder capacity , compliance and number of uninhibited contractions with improvement on oral oxybutynin was 70.6 % , 64.3 % and 66.7 % , respectively . ### conclusions Intravesical lidocaine can improve bladder capacity and compliance and decrease the number of uninhibited contractions in many children with neurogenic bladder caused by myelomeningocele. These observations suggest that intravesical lidocaine has effects on the neurogenic bladder that improve bladder dynamics. Although intravesical lidocaine testing may not reliably predict clinical response to oral oxybutynin at the prescribed dosages, a possible therapeutic role for intravesical lidocaine or similar agents should be explored further. | https://pubmed.ncbi.nlm.nih.gov/11371945/ | ### Instruction:

] | Statins have additive effects to vertebral bone mineral density in combination with risedronate in hypercholesterolemic postmenopausal women. Recent data suggest that statins used in the treatment of hypercholesterolaemia decrease fracture risk. In this study, we aimed to investigate prospectively whether statins have an additive effect to bisphosphonates (risedronate) according to the primary hypothesis that the addition of atorvastatin to risedronate would produce an increase, from baseline, in lumbar vertebrae and total hip BMD that was greater than that observed with risedronate alone. ### methods A total of 120 hypercholesterolaemic postmenopausal women with osteoporosis or osteopenia were randomized to receive risedronate (5 mg/day) or risedronate (5 mg/day) plus atorvastatin (20 mg/day). Changes in bone mineral density in the lumbar spine and hip, and serum lipid and glucose metabolism changes were assessed. ### results Compared with risedronate alone , at 6 months , risedronate plus atorvastatin produced significantly greater increases in the bone mineral density of the lumbar spine ( 1.58 % versus 0.75 % , p < 0.05 ) . We found no difference after therapy in BMD of the total hip (1.2% versus 1.1%). risedronate plus atorvastatin therapy had favorable effects on the serum lipid profile: LDL and total cholesterol. Serum fasting glucose and HbA1c levels were not affected during the treatments. ### conclusion Statins have modest additive effects to bisphosphonates in improving lumbar spine bone mineral density in hypercholesterolaemic postmenopausal women with established osteoporosis-osteopenia.

The aim of this study was to investigate the mutagenic and antigenotoxic effects of different doses of the flavonoid , apigenin , alone and in combination with the antitumor drugs , cyclophosphamide and doxorubicin , in vitro and in vivo . Using bacterial reverse mutation inhibition in vitro, with and without metabolic activation, the effect of apigenin (10-400 μg/plate) was studied on genotoxicity induced by cyclophosphamide (800 μg/plate) and by doxorubicin (0.2 μg/plate). Subsequent to a dose-finding study in vivo, CD1 mice were treated with either cyclophosphamide (40 mg/kg, i.p.) or doxorubicin (5 mg/kg, i.p.) with or without co-administration of apigenin (1-100 mg/kg, p.o.). Micronuclei were determined microscopically in blood smears and glutathione peroxidase (GPX), superoxide dismutase (SOD) and total antioxidative status (TAS) in whole blood, erythrocytes and plasma, respectively. Apigenin decreased doxorubicin-induced, but not cyclophosphamide-induced mutagenicity in vitro. In vivo, apigenin caused a statistically significant decrease in micronucleus frequency in response to cyclophosphamide, possibly due to active flavonoid metabolite formation or inhibition of cyclophosphamide metabolic activation. In animals treated with apigenin and doxorubicin, a significant decrease in micronucleus frequency was not observed, probably due to interindividual variability. No changes in GPX, SOD or TAS were observed in response to either cytotoxic agents or the flavonoid, possibly due to limited metabolic transformation of the drugs at the doses used.

] | [] | Treatment of peripheral T-cell lymphoma: are we data driven or driving the data? Peripheral T-cell lymphomas (PTCL) are a group of uncommon and heterogeneous malignancies arising from a postthymic or mature T-lymphocyte. The treatment of PTCL remains a challenging endeavor. Compared with the more common aggressive B-cell lymphomas, more patients with PTCL will be refractory to initial therapy and those who achieve responses often will have shorter progression-free survival. Despite retrospective data that suggest that anthracycline-based multiagent chemotherapy regimens may not provide a benefit compared with nonanthracycline regimens, nonanthracycline-based regimens, with the notable exception of L-asparaginase regimens for extranodal NK/T-cell lymphoma, have been disappointing so far. Based on phase II evidence and subset analyses available, we believe that the addition of etoposide to standard regimens and consolidation of first remissions with autologous stem cell transplantation (autoSCT) provides the best outcome in patients with PTCL and currently use CHOEP followed by ASCT for eligible patients with the common PTCL subtype: PTCL-NOS, AITL, and ALK negative ALCL. For those with ALK-positive ALCL standard CHOP or CHOEP is appropriate with consideration of ASCT only for those with high-risk disease. Other strategies to incorporate additional agents, such as with dose-adjusted EPOCH or sequential CHOP-ICE regimens are logical options; however, they lack the supporting literature of CHOEP. Whereas the above recommendation is our current off-protocol approach, with the possible exception of low risk ALK positive ALCL, none of these choices is supported by strong enough data to supplant a well-conceived clinical trial as the truly preferred strategy in PTCL. The novel agents , romidepsin , pralatrexate , and brentuximab vedotin , are currently approved in the relapsed/refractory setting . These agents are being studied as additions or substitutions for other agents in up-front multiagent chemotherapy regimens. In the relapsed/refractory setting, both pralatrexate and romidepsin remain well-studied choices with some patients achieving a response with durability. Clinical trials of new agents in PTCL continue to be a valuable option and an important part of routine patient management as progressive disease often is seen. Lastly, we believe patients with relapsed/refractory PTCL should be considered for allogeneic stem cell transplantation if a suitable response is demonstrated and a willing donor is available. | https://pubmed.ncbi.nlm.nih.gov/23568456/ | ### Instruction:

This study investigated the effect of the antineoplastic agent gemcitabine (dFdC) in combination with cyclosporine (CsA) or with FK506 on acute heart allograft rejection in a rat model. ### methods Transplantations were performed in the fully allogeneic Lewis-to-Brown Norway strain combination. dFdC, CsA, and FK506 single-drug therapy and combinations of dFdC with CsA and FK506 were administered at various dosages starting on day 1 to prevent and on day 4 to treat acute rejection until day 20. Animals who did not reject their graft were intraperitoneally injected with 108 splenic donor-type lymphocytes. In addition, Lewis and third-party skin grafts were transplanted to these animals. ### results Mean graft survival times under CsA, FK506, and dFdC monotherapy were 18.3/63.7 days (1 mg/5 mg per kg), 41.7 days, and 24.7/38.7 days (100 microg/150 microg per kg), respectively. CsA and FK506 in combination with dFdC prolonged graft survival to more than 100 days (CsA) and more than 95.2 days (FK506). Graft survival after treatment of an ongoing rejection was 21.5/38.3 days for CsA (1 mg/5 mg per kg) and 17.7/59.2 days for dFdC (100 microg/150 microg per kg). The combination of CsA+dFdC prompted indefinite survival of five of six hearts. Lymphocyte inoculation did not induce graft rejection. Notably, none of the Lewis, but all third-party, skin grafts were rejected immediately. Histomorphologic analysis of grafted hearts, however, demonstrated typical features of chronic rejection. ### conclusions The combination of CsA and FK506 with low-dose dFdC exerts a synergistic effect in the prevention and treatment of acute allograft rejection in this model. Although chronic rejection could not be prevented, strain-specific tolerance was achieved. Therefore, combining standard immunosuppressants with dFdC is a novel, promising strategy for prevention and treatment of acute allograft rejection. | https://pubmed.ncbi.nlm.nih.gov/14557751/ | ### Instruction:

Although chronic rejection could not be prevented, strain-specific tolerance was achieved. Therefore, combining standard immunosuppressants with dFdC is a novel, promising strategy for prevention and treatment of acute allograft rejection.

] | [] | Erythropoietin receptor expression and its relationship with trastuzumab response and resistance in HER2-positive breast cancer cells . Resistance to trastuzumab is a major issue in the treatment of human epidermal growth factor receptor 2 (HER2)-positive breast cancer. Several potential resistance mechanisms have been investigated, but the results are controversial and no conclusion has been reached. erythropoietin receptor (EPOR) may function in cell growth, and expressed in various cancer cells. Because the downstream signaling pathways for EPOR and HER2 partially overlapped, we hypothesized that EPOR may play a role in the inhibition effect of trastuzumab and resistance to trastuzumab. Here, we detected the expression of EPOR mRNA and protein in HER2-positive breast cancer cell lines and tissues. EPOR expressed in SKBR3, MDA-MB-453, and UACC-812 cell lines, but not in BT474. Of the 55 HER2-positive cancer tissues, EPOR was positive in 42 samples and highly expressed (H-score ≥ 25) in 24 by immunohistochemistry. The difference between EPOR expression and Ki67 index was significant (P = 0.033), and EPOR expression also positively correlated with higher pathological stage (Spearman correlation coefficient = 0.359; P = 0.007). Exogenous EPO antagonized trastuzumab-induced inhibition of cell proliferation in HER2/EPOR dual-positive breast cancer cells. We then exposed SKBR3 cells to trastuzumab for 4 months to obtain trastuzumab-resistant SKBR3 cell line, which demonstrated higher phosphorylated EPOR level, higher EPO expression and more extracellular secretion than non-resistant parental SKBR3 cells. Downregulation EPOR expression using short hairpin RNA resensitized trastuzumab-resistant cells to this drug, and SKBR3 cells with EPOR downregulation demonstrated attenuated trastuzumab resistance after the same resistance induction. EPOR downregulation plus trastuzumab produced a synergetic action in the inhibition of cell proliferation and invasion in SKBR3 and MDA-MB-453 cell lines. Therefore, EPOR expression may be involved in tumor progression and proliferation in HER2-positive breast cancer. EPO/EPOR contributes to the mechanism of trastuzumab resistance in SKBR3 cell lines, and EPOR downregulation can reverse the resistance to trastuzumab and increase the inhibition effect of this drug. | https://pubmed.ncbi.nlm.nih.gov/23117856/ | ### Instruction:

Both paclitaxel ( Taxol ; Bristol-Myers Squibb Company , Princeton , NJ ) and ifosfamide have been demonstrated to be active agents in patients with clinically defined platinum-refractory ovarian cancer . While there might be interest in combining these two drugs as salvage therapy for this disease, the recent inclusion of paclitaxel as initial therapy for advanced ovarian cancer, along with a platinum agent (cisplatin or carboplatin), makes it unlikely that paclitaxel and ifosfamide will be used clinically in this malignancy.

] | [] | Drug susceptibility testing and pharmacokinetics question current treatment regimens in Mycobacterium simiae complex disease. The Mycobacterium simiae complex bacteria can cause opportunistic infections in humans. In the case of definite disease, there are no evidence-based treatment regimens and outcomes are very disappointing. To increase the evidence base underpinning treatment regimens for M. simiae complex disease, drug susceptibility patterns and rifampicin/ethambutol synergy were assessed retrospectively in 69 clinical M. simiae complex isolates from 60 patients (22 patients with M. simiae, 24 with Mycobacterium lentiflavum, 8 with Mycobacterium triplex, 5 with Mycobacterium parascrofulaceum and 1 with Mycobacterium stomatepiae) submitted to the mycobacteriology laboratory at National Jewish Health (Denver, CO). Quantitative drug susceptibility testing (DST) was performed using the radiometric BacTec 460 macrodilution method. Results were related to pharmacokinetic (PK) measurements, where available. All M. simiae complex species proved susceptible to clarithromycin and , to a lesser extent , rifabutin , clofazimine , streptomycin and moxifloxacin . Synergy or additive action between rifampicin and ethambutol was observed for all species except M. simiae. Mycobacterium simiae is poorly susceptible in vitro to rifampicin and ethambutol alone as well as in combination; PK measurements support the limited efficacy of these drugs against M. simiae. The triple-drug regimen of a rifamycin, ethambutol and a macrolide may be advised to treat disease caused by M. lentiflavum, M. triplex, M. parascrofulaceum and M. stomatepiae; for M. simiae, this regimen appears less active. These findings may partly explain the limited treatment results in M. simiae disease. A treatment regimen including a macrolide, moxifloxacin and one or two additional drugs based on DST results may be advisable; clofazimine and amikacin or streptomycin are potential candidates. | https://pubmed.ncbi.nlm.nih.gov/22099521/ | ### Instruction:
