In subgroup analyses of specific ARBs, switching between different ARBs was allowed. Case reports demonstrate that there is some degree of angioedema cross-reactivity between ACE inhibitors and ARBs; however, the reports fail to describe the incidence of or identify the mechanism for this reaction. Correspondence to Björn Pasternak, MD, PhD. Variations in compliance, persistence, and switching behavior were detected between specific ACE inhibitors, but not between specific ARBs. This large nationwide cohort study found no significant association between use of ARBs and the risk of incident cancer overall compared with use of ACE inhibitors. Risk of incident cancer according to duration of angiotensin receptor blocker (ARB) use compared with any angiotensin-converting enzyme inhibitor use in a nationwide cohort in Denmark, 1998 to 2006. We also performed exploratory analyses of lung cancer by histological type: small-cell carcinoma, adenocarcinoma, squamous cell carcinoma, and other/unspecified types. Figure 3 shows that none of the specific ARBs was associated with significantly increased risk of incident cancer overall compared with ACE inhibitors. Using participants' unique personal identification numbers, we linked individual-level information from nationwide registries on filled drug prescriptions, cancer diagnoses, and potential confounders. Arbs with betting exchanges As of today, there are not so many sports betting exchanges, where the most popular are Betfair, Betdaq, Matchbook and Smarkets. Risk estimates were similar for men and women and across specific ARBs and did not increase with increasing duration of exposure. Given the narrow CIs, a 4% risk increase associated with ARB exposure could be excluded. Among 107 466 ARB users, 3954 cases of cancer were detected during 312 753 person-years of follow-up compared with 6214 cases during 435 207 person-years of follow-up in 209 692 angiotensin-converting enzyme inhibitor users (adjusted rate ratio, 0.99; 95% confidence interval, 0.95 to 1.03). code!switching!between!arabic!and!english,!social!motivations!and! The views expressed in this article are the personal views of the author, and do not necessarily represent the position of the Danish Medicines Agency. The other authors report no conflicts. *Adjusted for calendar year, age in 5-year intervals, sex, socioeconomic class, degree of urbanization, number of hospitalizations in the previous 3 years, Charlson comorbidity index, and use of other antihypertensives (β-blockers, thiazides, and calcium channel blockers). Applying a Poisson regression model (log-linear regression of the counts of cancer using the logarithm of the follow-up time as offset), we estimated the RR for incident cancer or cancer mortality comparing ARB and ACE inhibitor users (SAS version 9.1). The study was approved by the Danish Data Protection Agency. A trial of 54 patients, all of whom experienced ACE inhibitor–induced angioedema, was performed to determine the safety of using other antihypertensive medications in … Strengths of our study include the use of individual-level nationwide registry data and a comprehensive pharmacoepidemiological design. Thus, each participant could contribute several distinct use and past use episodes that, when added together, represented this participant's total person-time of use and past use, respectively. Can angiotensin receptor-blocking drugs perhaps be harmful in the COVID-19 pandemic? Figure 2. Dallas, TX 75231 In these analyses, 365 defined daily doses were defined as equivalent to 1 year, and the cumulative received doses were counted starting after the lag period. However, if they later refilled a prescription and fulfilled criteria for use, past users could again be recategorized and contribute person-time to the user group. Results were similar when ARBs were compared with other antihypertensive drugs in a sensitivity analysis. However, type 2 receptor activation would be expected to have antitumor effects,28–31 although data are somewhat conflicting.27,32 Safety studies in animals have also demonstrated the absence of carcinogenicity with high doses of ARBs.33–39, Some strengths and limitations of our large nationwide cohort study deserve particular mention. After cohort entry, defined by the date of filling the first prescription for an ARB or ACE inhibitor, we allowed for a 180-day lag period. To adjust for comorbidity, we used diagnostic information from the National Patient Registry,22 which documents all hospitalizations and outpatient hospital visits in the country, and calculated the Charlson comorbidity index23,24 (cancer diagnoses were not included) on the basis of data registered before cohort entry. Mineralocorticoid Receptor Antagonists in CKD: In Need of a Few Large Trials. 1-800-AHA-USA-1 The observed significant association between ARB use and male genital cancer should therefore be viewed in the context of multiple testing because it could represent a chance finding. In exploratory analyses of lung cancer by histological type, adjusted RRs were 0.80 (95% CI, 0.65 to 0.99) for small-cell carcinoma (n=128 among ARB users), 1.24 (95% CI, 1.01 to 1.52) for adenocarcinoma (n=173), 0.86 (95% CI, 0.67 to 1.12) for squamous cell carcinoma (n=87), and 0.80 (95% CI, 0.65 to 0.98) for other/unspecified types (n=136). §As captured by the National Patient Registry (documents hospitalizations and outpatient hospital visits).

The primary objective of this study was to evaluate BP control after switching of ARB therapy in patients … Table 2. While intravenous medications may be more bioavailable and have greater effects, some oral drugs produce serum levels comparable to those of the parenteral form. In case of a switch from ACE inhibitors to ARBs, it seems reasonable to stop ACE inhibitors and start ARBs the following day at an equivalent dose. During the lag period, participants did not contribute person-time. Switching from intravenous (IV) to oral (PO) therapy as soon as patients are clinically stable can reduce the length of hospitalization and lower associated costs. The American Heart Association is qualified 501(c)(3) tax-exempt Among ARB users, 894 (0.8%) had filled only 2 prescriptions and 106 572 (99.2%) had filled at least 3 prescriptions. Effect measures were adjusted for sex, age in 5-year intervals, calendar year, socioeconomic class, degree of urbanization, and use of other antihypertensives (β-blockers [C07A], calcium channel blockers [C08CA, C08D], and thiazides [C03A]). ARBs, by contrast, went through testing on top of these more modern medicines. Pregnant women and those planning a pregnancy — due to risks to the fetus. (Micromedex Healthcare series, Vol 119) 2: Ramipril 5-10mg daily is considered equivalent to Captopril 50mg bd for the treatment of hypertension (Micromedex Healthcare series, Vol 119) Monitoring requirements when switching ACE-inhibitors In subgroup analyses, there was a significant association between ARB use and cancer of male genital organs (rate ratio, 1.15; 95% confidence interval, 1.02 to 1.28), but no significantly increased risk of any of the other 15 cancer subgroups, including lung cancer (rate ratio, 0.92; 95% confidence interval, 0.82 to 1.02). Furthermore, because risk of prostate cancer did not appear to increase with increasing duration of exposure, biological plausibility of this association is less likely. The main one in this list is Betfair as it has obtained quite extensive popularity among thousands of bettors all over the world. RR indicates rate ratio; CI, confidence interval. All rights reserved. Furthermore, we did not detect increased risk associated with increasing exposure time; this analysis included a subgroup with >5 years of cumulative exposure (RR, 1.01; 95% CI, 0.94 to 1.08). By continuing to browse this site you are agreeing to our use of cookies. Users of ARBs or ACE inhibitors who subsequently stopped treatment were recategorized to a distinct group of patients—past users—and contributed person-time to this group from the day the maximum gap time after a prescription was exceeded. Furthermore, a comparison to nonusers would have introduced a surveillance bias for cancer because patients under antihypertensive treatment are more likely to be examined by healthcare providers. between. Rifampin (Rifadin) reduces the blood levels of losartan, and fluconazole (Diflucan) reduces the conversion of losartan to its active form. If 2 prescriptions overlapped, the overlap was disregarded and exposure time was counted from the dispensing day of the most recent prescription. Our finding of no significant association between ARBs and cancer contrasts with that of a recently published meta-analysis of randomized trials by Sipahi et al,4 who found a modestly increased risk of new cancer among patients treated with ARBs (RR, 1.08; 95% CI, 1.01 to 1.15) compared with placebo or comparator drugs. Breast and female genital organs subgroups were estimated in women only (173 657 person-years of follow-up among ARB users).

We cannot, however, exclude the possibility of unmeasured confounding, because differences between ARB and ACE inhibitor users may still exist. Relation between drug treatment and cancer in hypertensives in the Swedish Trial in Old Patients With Hypertension 2: a 5-year, prospective, randomised, controlled trial, Angiotensin-converting enzyme inhibitors, calcium channel blockers, and breast cancer. Clinical outcomes after endovascular therapy among hemodialysis patients with peripheral artery disease stratified by the primary kidney disease. ‡Excludes basal cell carcinoma. Individuals diagnosed with any cancer before cohort entry (back to 1978) were excluded. This retrospective data-base analysis study was conducted to compare mainte-nance of BP control in patients who continue olmesartan monotherapy with patients who switch to therapy with another ARB. We grouped cancers according to anatomic site (International Classification of Diseases codes in Table I in the online-only Data Supplement) and subdivided the respiratory group into lung and nonlung.

All rights reserved. We also analyzed cancer risk according to total duration of ARB use (estimated by cumulative received defined daily doses) compared with the overall risk associated with ACE inhibitor use. ARB use was also associated with a significantly reduced risk of the subgroup of other cancers in our study; thus, associations pointed in different directions. Department of Epidemiology Research, Statens Serum Institut, Artillerivej 5, 2300 Copenhagen S, Denmark. Hudson (1980) distinguished between code switching, code mixing, and borrowing in his section on the mixture of varieties.

Single-cell RNA-seq data analysis on the receptor ACE2 expression reveals the potential risk of different human organs vulnerable to 2019-nCoV infection. Furthermore, although the angiotensin receptor system is involved in the process of carcinogenesis, experimental data point, if anything, toward beneficial effects of angiotensin signaling inhibition. Calendar year and age categories were collapsed to include wider intervals in these subgroups because of small numbers of exposed cases and therefore nonconvergence of statistical models with original category definitions. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Kuster et al., on pages 1801–1803. A more conservative definition that did not allow gaps between prescriptions, thereby probably limiting analyses to those with more consistent drug exposure, yielded results very similar to the main analysis. †Adjusted for calendar year in 2-year intervals, age in 10-year intervals, sex, socioeconomic class, degree of urbanization, number of hospitalizations in the previous 3 years, Charlson comorbidity index, and use of other antihypertensives (β-blockers, thiazides, and calcium channel blockers). In a subgroup analysis, there was no significant association between ARBs and lung cancer. (p. 51). Medications involved in switch therapy include antibiotics, … Diagnoses of incident cancer were identified via the Danish Cancer Registry,20 which documents all cases of cancer in the country with high completeness and validity20; cancers are classified according to the International Classification of Diseases. Unauthorized A dose equivalency between enalapril:captopril of 1:7.5 is suggested for the treatment of hypertension. Within each treatment episode, a gap between prescriptions of up to 50% of the duration of the preceding prescription (in defined daily doses) was accepted to leave room for variations in drug intake habits. Angiotensin II receptor blockers (ARBs) are also used to prevent diabetes and reduce the risk of stroke in patients with high blood pressure and an enlarged heart, and they may also prevent the recurrence of atrial fibrillation. A recent meta-analysis of randomized trials suggested that use of angiotensin receptor blockers (ARBs) may be associated with a modestly increased risk of incident cancer, particularly lung cancer. Among patients who remained in the cohort after this extended lag period, 64 036 ARB users were followed up during 140 562 person-years and compared with 89 259 ACE inhibitor users who were followed up during 163 617 person-years; ARB use was not associated with cancer (adjusted RR, 0.99; 95% CI, 0.95 to 1.03).
