Alpha 1-blocker combination therapy for hypertension.

Combination therapy is a cost-effective and rational approach to treatment of severe hypertension and of mild to moderate hypertension that is refractory to monotherapy. The method has several advantages, most notably improved tolerability and enhanced antihypertensive efficacy. Long-term prospective studies are needed to confirm that such agents as calcium channel blockers, ACE inhibitors, and alpha 1 blockers reduce end-organ damage more effectively than do older antihypertensive drugs. However, scientific evidence strongly suggests that reducing risk factors for end-organ damage reduces heart, brain, kidney, and large-artery injury. Alpha 1 blockers appear to be a particularly suitable choice for use in combination regimens. The only class of agents that should be avoided in combination with alpha 1 blockers is central alpha agonists; all other agents act in an additive or synergistic fashion. Unlike diuretics and beta blockers, alpha 1 blockers do not adversely affect serum lipid, glucose, or insulin levels. In fact, alpha 1 blockers may improve these measurements and also counteract the adverse effects of other antihypertensive agents on them. Alpha1-blocker therapy may bring about regression of LVH, and it does not have deleterious effects on disorders that often coexist with hypertension (e.g., gout, chronic obstructive lung disease, peripheral ischemia).

Cost-effectiveness analysis of hypertension treatment: controlled release nifedipine and candesartan low-dose combination therapy in patients with essential hypertension--the Nifedipine and Candesartan Combination (NICE-Combi) Study.

Societal interest in pharmaco-economic analysis is increasing in Japan. In this study, the cost-effectiveness of low-dose combination therapy with controlled release nifedipine plus candesartan and up-titrated monotherapy with candesartan was estimated, based on the results of the NICE-Combi study. The NICE-Combi study was a double-blind, parallel arm, randomized clinical trial to compare the efficacy of low-dose combination therapy of controlled release nifedipine (20 mg/day) plus candesartan (8 mg/day) vs. up-titrated monotherapy of candesartan (12 mg/day) on blood pressure control in Japanese patients with mild to severe essential hypertension who were not sufficiently controlled by the conventional dose of candesartan (8 mg/ day). The incremental cost effectiveness of each cohort during the 8-week randomization period was compared, from the perspective of a third-party payer (i.e., insurers). The average total cost per patient was 29,943 Japanese yen for the combination therapy group and 33,182 Japanese yen for the candesartan monotherapy group, while the rate of achievement of the target blood pressure was significantly higher in the combination therapy group than in the up-titrated monotherapy group. In the combination therapy group, higher efficacy and lower incremental treatment cost ("Dominance") were observed when compared to the monotherapy group. The sensitivity analyses also supported the results. In conclusion, these results suggest that combination therapy with controlled release nifedipine and low-dose candesartan (8 mg) is "dominant" to up-titrated candesartan monotherapy for the management of essential hypertension. This conclusion was robust to sensitivity analysis.

Use of pharmacodynamic parameters to predict efficacy of combination therapy by using fractional inhibitory concentration kinetics.

Combination therapy with antimicrobial agents can be used against bacteria that have reduced susceptibilities to single agents. We studied various tobramycin and ceftazidime dosing regimens against four resistant Pseudomonas aeruginosa strains in an in vitro pharmacokinetic model to determine the usability of combination therapy for the treatment of infections due to resistant bacterial strains. For the selection of an optimal dosing regimen it is necessary to determine which pharmacodynamic parameter best predicts efficacy during combination therapy and to find a simple method for susceptibility testing. An easy-to-use, previously described E-test method was evaluated as a test for susceptibility to combination therapy. That test resulted in a MICcombi, which is the MIC of, for example, tobramycin in the presence of ceftazidime. By dividing the tobramycin and ceftazidime concentration by the MICcombi at each time point during the dosing interval, fractional inhibitory concentration (FIC) curves were constructed, and from these curves new pharmacodynamic parameters for combination therapy were calculated (i.e., AUCcombi, Cmax-combi, T>MIC-combi, and T>FICi, where AUCcombi, Cmax-combi, T>MIC-combi, and T>FICi are the area under the FICcombi curve, the peak concentration of FICcombi, the time that the concentration of the combination is above the MICcombi, and the time above the FIC index, respectively). By stepwise multilinear regression analysis, the pharmacodynamic parameter T>FICi proved to be the best predictor of therapeutic efficacy during combination therapy with tobramycin and ceftazidime (R2 = 0.6821; P < 0.01). We conclude that for combination therapy with tobramycin and ceftazidime the T>FICi is the parameter best predictive of efficacy and that the E-test for susceptibility testing of combination therapy gives promising results. These new pharmacodynamic parameters for combination therapy promise to provide better insight into the rationale behind combination therapy.

Acute sensorineural hearing loss associated with peginterferon and ribavirin combination therapy during hepatitis C treatment: outcome after resumption of therapy.

Peginterferon and ribavirin combination therapy for the treatment of hepatitis C virus (HCV) is well known to be associated with significant adverse effects. Sensorineural hearing loss, that in most cases is unilateral, has been reported as a consequence of therapy with both non-pegylated and pegylated interferon (pegIFN) but is not a well-known adverse effect. We report a 45-year-old Caucasian woman who developed acute sensorineural hearing loss 2 mo after starting therapy with pegIFN-alpha 2b and ribavirin for the treatment of chronic HCV, genotype 1a. She did not report the hearing loss to the hepatitis clinic until 1 mo, later whereupon therapy was promptly discontinued. Although her serum alanine aminotransferase (ALT) normalized and her HCV-RNA became undetectable after 12 wk of pegIFN and ribavirin therapy, after discontinuation, her HCV-RNA became detectable with significant elevations of serum ALT. Four months after initial discontinuation, the patient re-commenced pegIFN and ribavirin combination therapy. After 44 of 48 wk of therapy, the patient's liver biochemistry has normalized and the HCV-RNA is undetectable. She has not developed worsening of her hearing loss and hearing on the left-side is unaffected. Both patients and physicians should be aware that sensorineural hearing loss may occur with pegIFN therapy. Our experience suggests that re-institution of therapy is not always associated with further hearing impairment.

Rescue of combination therapy failures using infliximab, while maintaining the combination or monotherapy with methotrexate: results of an open trial.

OBJECTIVE: To assess the possible clinical and biological rescue of rheumatoid arthritis (RA) in 16 patients who were still active despite intensive combination therapy after receiving infliximab following the Anti-Tumour necrosis factor Trial in Rheumatoid Arthritis with Concomitant Therapy (ATTRACT) schedule. METHODS: Sixteen patients who were still active despite combination therapy with optimal doses of methotrexate (MTX 15-17.5 mg/week) and cyclosporin A (CsA 2.5-3.5 mg/day) received infliximab. Ten received their combination plus infliximab (Combi), and six received infliximab plus MTX alone (Mono). The follow-up was carried out for 30 weeks in all patients and for 46 weeks in eight. Efficacy and safety were examined. RESULTS: At entry, the mean disease activity score (DAS) was 5.6 (all patients had a DAS >3.7). After therapy, eight of 10 patients in Combi and four out of six in Mono showed an improvement of >50% in the initial swollen joint count, yet only one patient reached 50% improvement in the initial DAS after 30 weeks, and one patient had a DAS <2.4 (low disease activity). Of the eight patients who reached 46 weeks of follow-up, three showed an improvement in DAS of 50% and two had a DAS <2.4. When considering the change over time, the difference between DAS at entry and at week 30 was statistically significant only in patients receiving MTX plus CsA, while it was not significant in those receiving MTX only. Two patients developed recurrent febrile upper respiratory infections in the Combi therapy group, while two had a single febrile infection in the MTX alone group. Two patients became strongly anti-cardiolipin positive (IgM >40 MPL) and one developed a coronary syndrome. CONCLUSION: Infliximab can be added incrementally to MTX plus CsA, with favourable results in terms of efficacy and safety over time in severe rapidly aggressive and progressive RA. Finally, minor evidence emerged for a stronger efficacy of the Combi treatment compared with Mono.

Mutations in the NS5B region of the hepatitis C virus genome correlate with clinical outcomes of interferon-alpha plus ribavirin combination therapy.

BACKGROUND AND AIM: Combination treatments of interferon-alpha (IFN) and ribavirin (RBV) are more effective than those of IFN alone in hepatitis C virus (HCV) infection. However, mechanisms of the action of the combination regimen are not well understood. To elucidate the viral genetic basis of IFN plus RBV combination therapy, genetic variabilities of HCV-1b were analyzed. METHODS: We performed pair-wise comparisons of full-length HCV genomic sequences in three patients' sera before and after initiation of IFN plus RBV treatment. Subsequently, we analyzed amino acid sequences of the NS5B region, which codes for the viral RNA-dependent RNA polymerase, and compared these with the outcomes of the therapy in 81 patients. RESULTS: Analysis of the entire HCV sequence in patients who received IFN plus RBV therapy did not show consistent amino acid changes between before and after the initiation of the therapy. NS5B sequence analyses revealed that mutations at positions 300-358 of NS5B, including polymerase motif B to E, occurred more frequently in a group of patients exhibiting a sustained viral response (SVR) or an end-of-treatment response (ETR) compared with a group of patients exhibiting a non-response (NR). Closer examination revealed that mutations at aa 309, 333, 338 and 355 of NS5B occurred significantly more frequently in the SVR plus ETR group than in the NR group (P = 0.0004). Multivariate analysis showed that the number of mutations at these four sites was an independent predictor of SVR plus ETR versus NR. CONCLUSIONS: Particular amino acid changes in the NS5B region of HCV may correlate with outcomes of IFN plus RBV combination therapy.

Major advantages of "early" administration of endocrine combination therapy in advanced prostate cancer.

Combination therapy with the antiandrogen flutamide and the luteinizing hormone-releasing hormone (LHRH) agonist [D-Trp6, des-Gly-NH2(10)] LHRH ethylamide or orchiectomy was administered to 268 patients with previously untreated metastatic stage D2 prostate cancer for an average of 1,191 d (3.26 y). Only 17 of the 268 evaluable patients (6.5%) showed no objective positive response to the combination therapy assessed according to the National Prostatic Cancer Project objective criteria of response. The median duration of the disease-free response was 2.23 y and median overall survival was 3.58 y. The median survival for patients with only 1-5 bone metastases was not yet reached at 8 y, but for patients with 6-10 bone lesions, 11-40 bone lesions, and multiple bone metastases (superscan), median survival was markedly reduced to 3.56, 2.36, and 1.76 y, respectively. Analysis of patients according to general symptomatology, pain, and performance status showed median survivals of 5.47, 2.71, and 2.1 y for minimal, moderate, and severe symptoms, respectively. The present data demonstrate that administration of combination therapy to stage D2 prostate cancer patients having 1-5 bone metastases adds a minimum of 4.4 y of good quality life compared with patients whose disease is slightly more advanced. Our findings clearly demonstrate the major importance of starting combination therapy as soon as possible after diagnosis of metastatic prostatic cancer.

Emergence of zidovudine and multidrug-resistance mutations in the HIV-1 reverse transcriptase gene in therapy-naive patients receiving stavudine plus didanosine combination therapy. STADI Group.

OBJECTIVE: Assessment of genotypic changes in the reverse transcriptase gene of HIV-1 occurring in antiretroviral naive patients treated by stavudine plus didanosine combination therapy. METHODS: Sequence analysis (codons 1-230) was performed after amplification of the reverse transcriptase gene from plasma samples collected at baseline and at the end of treatment from 39 previously treatment-naive patients treated for 24-48 weeks. RESULTS: At baseline, mutations associated with zidovudine resistance were detected in plasma from two patients: Asp67Asn/Lys219Gln and Leu210Trp. Among the 39 subjects, 18 (46%) developed mutations: one developed the Val75Thr/Ala mutation, four (10%) developed a Gln151Met multidrug-resistance mutation (MDR), associated in one of them with the Phe77Leu and the Phe116Tyr MDR mutations and 14 (36%) developed one or more zidovudine-specific mutations (Met41Leu, Asp67Asn, Lys70Arg, Leu210Trp, Thr215Tyr/Phe). The development of a Met41Leu zidovudine-specific mutation was associated with the development of a Gln151Met mutation in one patient. Other reverse transcriptase mutations known to confer resistance to nucleoside analogues were not detected. At inclusion, there was no statistical difference in HIV-1 load between patients who developed resistance mutations and those who did not. RNA HIV-1 load decrease was higher (P = 0.05) in patients who maintained a wild-type reverse transcriptase genotype (-2.22 log10 copies/ml) than in patients who developed resistance mutations (-1.14 log10 copies/ml). CONCLUSION: Stavudine/didanosine combination therapy is associated with emergence of zidovudine-related resistance or MDR mutations in naive patients. These findings should be considered when optimizing salvage therapy for patients who have received a treatment including stavudine/didanosine combination.

[Severe exacerbation of chronic hepatitis B during therapy with corticosteroids and lamivudine therapy and successful short-term combination therapy with interferon-beta and interferon-gamma].

Following an acute episode of undifferentiated collagenosis/autoimmune disease with joint pain, a 50-year-old female patient with known long-standing chronic hepatitis B was treated orally with corticosteroids (30 mg prednisolone in decreasing doses over a period of six months). During this treatment, exacerbation of hepatitis B and massive flare-up under simultaneous treatment with lamivudine occurred (GOT 530 U/L, GPT 791 U/L). Serology was positive for HBs-Ag and anti-HBc-lgM. HBV-DNA titer was > 400,000 copies/ml in polymerase chain reaction. Considering the increased risk of reactivation of autoimmune phenomena during a six months therapy with interferon-alpha, an intensive combination therapy with interferon-beta and -gamma (2 weeks: 1 x 3 MIU nIFN-beta Fiblaferon i.v.; 3 weeks: 1 x 3 MIU nIFN-beta i.v. plus 1 x 50 microg rIFN-gamma Imukine) was carried out over five weeks. After two months this resulted in a complete viral and biochemical response. During an observation period of twelve months no reactivation of the autoimmune disease occurred.

[Drug therapy of goiter. Iodine, thyroid hormones or combined therapy].

Recent in vitro and in vivo data indicate that intrathyroidal iodine deficiency is the most important factor for the development of endemic goitre. Normalisation of the thyroid iodine content is essential to achieve regression of hyperplasia of iodine-depleted thyroid tissue. As clinical studies clearly demonstrate iodine should always be part of therapy of euthyroid diffuse endemic goitre. After therapy with levothyroxine alone the intrathyroidal iodine deficiency remains unchanged, and relapse of goitre will soon occur. There are the following indications for conservative therapy of euthyroid diffuse endemic goitre: 1. Children and adolescents should be treated by iodine alone (100-200 micrograms/die). 2. For adults a combined therapy with levothyroxine (100 micrograms/die) plus iodine (200 micrograms/die) is to be preferred to avoid the possible induction of thyrotoxicosis or autoimmune thyroid disease by high iodine doses (monotherapy with iodine would need 400-500 micrograms/die). In addition no reduction of goitre volume can be expected in adults older than 40 years because of an increasing number of thyroid nodular formations. 3. During pregnancy the combination therapy has advantages as high iodine dosages of iodine, potentially dangerous for the foetus, can be avoided whereas goitre formation in the mother is effectively suppressed and iodine deficiency in mother and child is compensated. Goitre therapy should be carried out at least for 6 months. The efficacy of goitre therapy should be controlled by sonographic determination of thyroid volume at least once a year after the end of treatment. An effective goitre prophylaxis with 100-200 micrograms iodine per day is recommended following the actual therapy period.

Fixed combination therapy of hypertension: focus on valsartan/hydrochlorothiazide combination (Diovan/HCT).

Hypertension is a major risk factor for cardiovascular morbidity and mortality. Monotherapy of hypertension is often ineffective, since it controls approximately 50% of the blood pressure of hypertensive patients. For lowering blood pressure to less than 140/90 mmHg (or <130/80 mmHg among people with diabetes or chronic renal disease) according to JNC-7 guidelines, combination therapy of two or more drugs is often necessary. The combination of a diuretic with an angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin receptor blocker (ARB) is effective and provides the additional benefit of blocking the effects of angiotensin II, which is responsible for cardiovascular remodeling and its complications. ARBs may have an advantage over the ACEIs because they block the action of all angiotensin II directly, whereas ACEIs are ineffective in blocking angiotensin II generated by nonclassical ACE pathways. Valsartan (Diovan, Novartis) is one of the seven currently approved ARBs in the USA for the treatment of hypertension, and it has been shown to be very effective in controlling blood pressure given once-daily in doses of 80-160 or 320 mg. Its fixed combination with hydrochlorothiazide (HCT) is even more effective in controlling blood pressure in 70% of the cases. The most commonly used combinations are valsartan/HCT (Diovan/HCT), 80/12.5 and 160/12.5 mg given once-daily.

[A clinical study on combination therapy of antimicrobial agents for complicated urinary tract infection--with special reference to combination with clarithromycin].

PURPOSE: To confirm the clinical efficacy of the combined therapy to complicated urinary tract infection (UTI), we conducted a comparative clinical study of the combined therapy with ciprofloxacin (CPFX) and clarithromycin (CAM) acting an biofilm elimination or CPFX alone in patients with complicated UTI. PATIENTS AND METHODS: The study was carried out in patients with complicated UTI having WBCs with 5/hpf or more in urinary sediment and bacteriuria at least 10(4) CFU/ml. The combined therapy was CPFX and CAM, each 600 mg/day, for 14 days, and the single therapy group CPFX, 600 mg/day, for 14 days. On Day 7 and 14, the eradication rate and efficacy rate (according to the criteria of the Japanese UTI committee) were determined. In the patients with indwelling catheter, the surface of the catheter tip was observed under a scanning electron microscope (SEM) on Day 14. RESULTS: In both cases with and without catheters, clinical efficacy was higher in the combined therapy group than in the single therapy group. In particular, the efficacy rates at 14 Day were significantly higher in the former group. Furthermore, we investigated the therapeutic effect in the below MIC breakpoint of CPFX in complicated UTI. The combined therapy group showed a higher clinical efficacy in both cases with and without indwelling catheter than the single therapy group, although there was not statistically significant. Biofilm on the surface of the catheter tip was eliminated in 75% of the combined therapy group. However, none of the biofilm was eliminated in the single therapy group. CONCLUSION: From the above results, we surmise that the combined use of CPFX and CAM will show some degree of efficacy in eliminating both the causative organism and its biofilm in the complicated UTI.

Biguanides and sulfonylureas as combination therapy in NIDDM.

Oral combination therapy with biguanides (metformin) and sulfonylureas is discussed. The rationale for the use of this combination is based on the different sites of action of the two kinds of drugs and the possibility for obtaining additive or potentiating effects and reduced side effects. The clinical usefulness of chlorpropamide and glyburide in combination with metformin has been demonstrated in some clinical trials. The combination may provide satisfactory glycemic control for several years, and possibly insulin therapy can be postponed or even avoided. No special safety problems are encountered with the use of the combination other than those attributed to the use of metformin or sulfonylurea alone, i.e., lactic acidosis and hypoglycemia, respectively. The lethality risks of these associated conditions are comparable. It is concluded that more data are needed to evaluate the full clinical potential and the mechanism of action of oral combination therapy.

[Combination therapy of high dose doxifluridine (5'-DFUR)+mitomycin C (MMC) for advanced or recurrent colorectal cancer. Joint Research Group in the Osaka Area for Combination Therapy of 5'-DFUR with Other Drugs].

A co-study was conducted on treatment with high dose 5'DFUR+MMC in order to determine its effectiveness as a systemic chemotherapy in patients with advanced and recurrent colorectal cancers. The treatment schedule included 5'-DFUR given orally at a dose of 1,600 mg/body/day for five consecutive days, a two-day discontinuation, then repeated medication with the above, and MMC injected intravenously at a dose of 6 mg/m2 once every four weeks. One course consisted of four weeks, and courses were repeated as long as tolerated by the patients. Twenty-nine patients were registered for the study and 28 cases were perfectly capable of anti-tumor responses. The response rate was 25.5%, including: CR, 2; PR, 5; NC, 11; and PD, 10 cases. Responding cases were found in metastases to the lung, cervical lymph node and abdominal wall. Response rate was especially high in pulmonary metastases at 41.7% (5/12 cases). The slight side effects were mostly gastrointestinal in nature and did not necessitate drug discontinuance. The results suggest that treatment with high dose 5'-DFUR+MMC is useful for advanced and recurrent colorectal cancers, especially those with pulmonary metastases.

Systemic inhibition of tumor growth by soluble Flk-1 gene therapy combined with cisplatin.

Soluble Flk-1, a soluble vascular endothelial growth factor (VEGF) receptor, is a potent inhibitor of angiogenesis, which could restrain growth and metastasis of some experimental tumors. However, antiangiogenic agents alone cannot eradicate tumor completely, and should be combined with other therapy to enhance their effects. In this study, we evaluated the antitumor activity of the combination therapy in the immunocompetent BALB/c mice bearing H22 hepatoma and Meth A fibrosarcoma, respectively. Mice were treated with either msFlk-1 i.m. at 100 microg/mouse once every 3 days for four times from day 3 after the tumor cell injection, cisplatin cycled twice (2 mg/kg i.p. on days 4 and 11 after the tumor cell inoculation), or both agents together. Tumor growth and survival time were continually observed. Antiangiogenesis in vivo was determined by CD31 immunohistochemistry. Assessment of apoptotic cells and histological analysis was also conducted in tumor tissues. Our results showed that the combination therapy could evidently improve antitumor efficacy, including tumor growth suppression, mice survival prolongation, tumor cell apoptosis augmentation as well as neovascularization inhibition as compared with controls, without serious adverse effects. Our data suggest that the combination of DDP with msFlk-1 is more effective to suppress tumor growth in mice than either agent alone, and this combination regimen showed its potential for future clinical application.

Combination therapy with flutamide and castration (orchiectomy or LHRH agonist): the minimal endocrine therapy in both untreated and previously treated patients with advanced prostate cancer.

One hundred fifty-four patients with clinical stage D2 prostate cancer with no previous endocrine therapy or chemotherapy received the combination therapy with the pure antiandrogen Flutamide and the LHRH agonist [D-Trp]LHRH ethylamide for an average of 22 months (3 to 49). The objective response to the treatment was assessed according to the criteria of the US NPCP. There was a 6.3-fold increase (29.2 versus 4.6%) in the percentage of patients who achieved a complete response as compared to the results achieved in 5 recent studies limited to removal (orchiectomy) or blockade (DES or Leuprolide) of testicular androgens. Only 4.5% of patients did not respond to the combination therapy as compared to an average of 18% by standard therapy. The duration of response is also significantly increased in the patients who received the combination therapy while the death rate was decreased by approximately 2-fold between 2 and 3 years of treatment. The marked (6.3-fold) improvement in the rate of complete objective responses coupled with the 4-fold decrease in the number of non responders, the increased duration of the positive responses and the 2-fold decrease in the death rate at 2 to 3 years of treatment are obtained with the combination therapy using Flutamide and castration with no or minimal secondary effects. In addition, two hundred nine patients with biopsy-proven stage D2 prostatic adenocarcinoma showing disease progression after orchiectomy, DES or an LHRH agonist used alone received the combination therapy with the pure antiandrogen Flutamide. In patients treated with DES, the estrogen was replaced by the LHRH agonist [D-Trp6]LHRH ethylamide. Objective response to therapy was also assessed according to the criteria of the US NPCP. Thirteen patients (6.2%) had a complete response to treatment while partial and stable responses were achieved in 20 (9.6%) and 39 (18.7%) patients, respectively, for a total objective response rate of 34.5%. The mean duration of response was 24 months. While, in the non responders, the median survival was 8.13 months with a 17% probability of survival at 2 years, the probability of survival of patients who showed partial and stable responses at 2 years was 87 and 67%, respectively. All patients who achieved a complete response are still alive. Considering the excellent tolerance coupled with an objective response observed in 34.5% of the patients, the combination therapy with Flutamide and castration (surgical or LHRH agonist) appears to be the treatment of choice for prostate cancer patients in relapse after standard endocrine therapy.
