Drug-Induced Hypertension

Different characteristics but comparable hypertension rates between two MMT "twin" clinics

BACKGROUND

Patients in methadone maintenance treatment (MMT) may develop age-related medical problems. Objective: To compare hypertension prevalence and its risk factors between two MMT clinics, having similar treatment guidelines, but different characteristics, one from Tel Aviv (TA) and one from Las Vegas (LV).

METHODS

Prevalence of hypertension (systolic ≥140 and or diastolic ≥90 mmHg BP) among all current 291 MMT patients in TA and 180 patients in LV were studied, including body mass index (BMI), drugs in urine, sociodemographic, and addiction history data.

RESULTS

Hypertension prevalence was comparable in TA (35.4%) and LV (34.4%), however TA patients were older (55.9 ± 9.5 vs. 45.5 ± 13.3, p < 0.001), with fewer females (22 vs. 42.2%, p < 0.001), fewer obese (BMI ≥30) (24 vs. 40.9%, p < 0.001), higher cocaine (21 vs. 7.8%, p < 0.001), and lower cannabis (14.1 vs. 32.4%, p < 0.001) and amphetamines (0 vs. 33.5%) users. Logistic regression found higher BMI to characterize hypertension in both clinics, but in TA also negative urine cocaine, benzodiazepine, and opioids screen, while in LV older age (≥50 y), male gender, and negative urine cannabis screen.

CONCLUSIONS

While TA was characterized with older patients, LV patients had a comparable hypertension rate, as obesity was more prevalent. No drug use was accompanied by higher BMI in TA and therefore associated with hypertension. Weight reduction, hypertension detection and treatment are recommended.

2024 ISFM and AAFP consensus guidelines on the long-term use of NSAIDs in cats

PRACTICAL RELEVANCE

Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used and are effective for the management of pain in cats. These Guidelines will support veterinarians in decision-making around prescribing NSAIDs in situations of chronic pain, to minimise adverse effects and optimise pain management. Information is provided on mechanism of action, indications for use, screening prior to prescription, use in the presence of comorbidities, monitoring of efficacy, and avoidance and management of adverse effects.

CLINICAL CHALLENGES

The cat's unique metabolism should be considered when prescribing any medications, including NSAIDs. Chronic pain may be challenging to detect in this species and comorbidities, particularly chronic kidney disease, are common in senior cats. Management of chronic pain may be complicated by prescription of other drugs with the potential for interactions with NSAIDs.

EVIDENCE BASE

These Guidelines have been created by a panel of experts brought together by the International Society of Feline Medicine (ISFM) and American Association of Feline Practitioners (AAFP). Information is based on the available literature, expert opinion and the panel members' experience.

Side effects of chronic systemic glucocorticoid therapy: what dermatologists should know

In dermatologists' clinical practice, the use of systemic glucocorticoids is recurrent for the management of different comorbidities that require chronic immunosuppression. The prescription of this medication requires caution and basic clinical knowledge due to the several adverse effects inherent to the treatment. However, different doubts may arise or inappropriate conduct may be adopted due to the lack of objective and specific guidelines for the screening, prophylaxis and management of complications from chronic corticosteroid therapy. Considering this problem, the authors carried out a narrative review of the literature to gather up-to-date data on adverse effects secondary to the chronic use of systemic glucocorticoids. The broad approach to this topic made it possible to review the pathophysiology and risk factors for these complications, as well as to develop updated orientation that can be used as a learning tool and quick reference for dermatologists during their clinical practice with glucocorticoids.

Are Proton Pump Inhibitors Contributing in Emerging New Hypertensive Population?

Balancing the therapeutic advantages of a medicine with its possible risks and side effects is an important part of medical practice and drug regulation. When a drug is designed to treat a particular disease or medical condition ends up causing additional risks or side effects that lead to the development of other serious health problems, it can have detrimental consequences for patients. This article explores the correlation between persistent proton pump inhibitor (PPI) use and hypertension, a common cardiovascular ailment. While PPIs are beneficial in treating various gastrointestinal problems, their availability without a prescription has resulted in self-medication and long-term use without medical monitoring. Recent findings have revealed a link between long-term PPI usage and increased cardiovascular risks, particularly hypertension. This study investigates the intricate mechanisms underlying PPI's effects, focusing on potential pathways contributing to hypertension, such as endothelial dysfunction, disruption of nitric oxide bioavailability, vitamin B deficiency, hypocalcemia, and hypomagnesemia. The discussion explains how long-term PPI use can disrupt normal endothelial function, vascular control, and mineral balance, eventually leading to hypertension. The article emphasizes the significance of using PPIs with caution and ongoing research to better understand the implications of these medications on cardiovascular health.

Cardiometabolic Effects of Cabergoline and Combined Oral Contraceptive Pills in Young Women with Hyperprolactinemia: A Pilot Study

Although dopaminergic agents are the drugs of choice in treatment of prolactin excess, women who cannot be treated with these agents are recommended to receive estrogen preparations. The aim of this study was to compare cardiometabolic effects of both treatment options. The study population included three groups of young women. Subjects with mild-to-moderate hyperprolactinemia received either low-dose cabergoline or oral combined contraceptives (ethinyl estradiol plus desogestrel), while normoprolactinemic women were drug-naive. Plasma prolactin, glucose homeostasis markers, lipids, circulating levels of uric acid, high-sensitivity C-reactive protein (hsCRP), fibrinogen and homocysteine, and the urinary albumin-to-creatinine ratio (UACR) were assessed at entry and six months later. Hyperprolactinemic women differed from normoprolactinemic ones in glucose homeostasis markers, high-density lipoprotein (HDL)-cholesterol, triglycerides, uric acid, hsCRP, fibrinogen, homocysteine and UACR. Cabergoline decreased total and monomeric prolactin levels, which was accompanied by normalization of glucose, insulin sensitivity, glycated hemoglobin, HDL-cholesterol, triglycerides, uric acid, hsCRP, fibrinogen, homocysteine and UACR. Despite a neutral effect on prolactin levels, combined contraceptives worsened insulin sensitivity and increased triglycerides, hsCRP, fibrinogen and UACR. At follow-up, cabergoline-treated women were characterized by a better cardiometabolic profile than women receiving ethinyl estradiol plus desogestrel. Our findings suggest that only cabergoline reduces cardiometabolic risk in young women with hyperprolactinemia.

Selective serotonin reuptake inhibitors and preeclampsia: A quality assessment and meta-analysis

Serotonin modulates vascular, immune, and neurophysiology and is dysregulated in preeclampsia. Despite biological plausibility that selective serotonin reuptake inhibitors (SSRIs) prevent preeclampsia pathophysiology, observational studies have indicated increased risk and providers may be hesitant. The objective of this meta-analysis and quality assessment was to evaluate the evidence linking SSRI use in pregnancy to preeclampsia/gestational hypertension. PubMed was searched through June 5, 2020 manually and using combinations of terms: "preeclampsia", "serotonin", and "SSRI". This review followed MOOSE guidelines. Inclusion criteria were: 1) Observational cohort or population study, 2) exposure defined as SSRI use during pregnancy, 3) cases defined as preeclampsia or gestational hypertension, and 4) human participants. Studies were selected that addressed the hypothesis that gestational SSRI use modulates preeclampsia and/or gestational hypertension risk. Review Manager Web was used to synthesize study findings. Articles were read and scored (Newcastle-Ottawa Quality Assessment Scale) for quality by two independent reviewers. Publication bias was assessed using a funnel plot and the Egger test. Of 179 screened studies, nine were included. The pooled risk ratio (random effects model) was 1.43 (95 % CI: 1.15-1.78, P < 0.001; range 0.96-4.86). Two studies were rated as moderate quality (both with total score of 6); others were high quality. Heterogeneity was high (I2 = 88 %) and funnel asymmetry was significant (p < 0.00001). Despite evidence for increased preeclampsia risk with SSRIs, shared risk factors and other variables are poorly controlled. Depression treatment should not be withheld due to perceived gestational hypertension risk. Mechanistic evidence for serotonin modulation in preeclampsia demonstrates a need for future research.

Evaluation and Management of Secondary Hypertension

Hypertension is a major cause of cardiovascular morbidity and mortality globally. Many patients with hypertension have secondary causes of hypertension that merit further evaluation. For example, secondary hypertension can result in target organ damage to the heart, kidneys, and brain independent of the effects of blood pressure. Several causes benefit from targeted therapies to supplement first-line antihypertensive agents. However, secondary hypertension is often underrecognized. The goal of this review is to highlight optimal approaches to the diagnosis and management of common causes of secondary hypertension, including primary aldosteronism, renovascular hypertension, obstructive sleep apnea, and drug-induced hypertension.

Management of Osteoarthritis: Expert Opinion on NSAIDs

Osteoarthritis (OA) is a leading cause of disability among older adults worldwide. Treatment aims are to alleviate inflammatory pain and improve physical function through non-pharmacological and pharmacological interventions. Non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as first-line therapy. However, selection is challenged by patient age, comorbidities and polypharmacy, and by the drug's benefit/risk balance, all of which together influence the risk of cardiovascular (CV), gastrointestinal (GI) and renal adverse events (AEs). While the efficacy profile of the various NSAIDs is delineated, the differences in their safety profile are not straightforward. This narrative review provides practical indications by a multidisciplinary Italian expert panel for general practitioners and specialists managing OA patients with chronic inflammatory pain; the goal is to maximize therapy efficacy while reducing untoward effects caused by inappropriate NSAID use. The discussion on the best approach to NSAIDs spanned the following topics: (1) patient evaluation: investigate pain origin, duration and components together with possible risk factors for CV, GI and renal AEs; (2) non-pharmacological interventions: the physiatrist provides a person-centered, holistic approach accounting for all patient aspects; (3) pharmacological interventions: patient profile and drugs' pharmacological properties affect NSAID selection, which drugs to be used in combination or to be avoided, formulation and therapy duration; (4) the pharmacologist's, general practitioner's and pain therapist's points of view; (5) NSAID safety: the individual baseline risk and the drug's safety profile are major determinants of CV, GI and renal risk; consider possible drug-drug interactions; (6) periodical re-evaluation of treatment response and adherence, using scales to assess pain and function.

Specific disruption of calcineurin-signaling in the distal convoluted tubule impacts the transcriptome and proteome, and causes hypomagnesemia and metabolic acidosis

Adverse effects of calcineurin inhibitors (CNI), such as hypertension, hyperkalemia, acidosis, hypomagnesemia and hypercalciuria, have been linked to dysfunction of the distal convoluted tubule (DCT). To test this, we generated a mouse model with an inducible DCT-specific deletion of the calcineurin regulatory subunit B alpha (CnB1-KO). Three weeks after CnB1 deletion, these mice exhibited hypomagnesemia and acidosis, but no hypertension, hyperkalemia or hypercalciuria. Consistent with the hypomagnesemia, CnB1-KO mice showed a downregulation of proteins implicated in DCT magnesium transport, including TRPM6, CNNM2, SLC41A3 and parvalbumin but expression of calcium channel TRPV5 in the kidney was unchanged. The abundance of the chloride/bicarbonate exchanger pendrin was increased, likely explaining the acidosis. Plasma aldosterone levels, kidney renin expression, abundance of phosphorylated sodium chloride-cotransporter and abundance of the epithelial sodium channel were similar in control and CnB1-KO mice, consistent with a normal sodium balance. Long-term potassium homeostasis was maintained in CnB1-KO mice, but in-vivo and ex-vivo experiments indicated that CnB1 contributes to acute regulation of potassium balance and sodium chloride-cotransporter. Tacrolimus treatment of control and CnB1-KO mice demonstrated that CNI-related hypomagnesemia is linked to impaired calcineurin-signaling in DCT, while hypocalciuria and hyponatremia occur independently of CnB1 in DCT. Transcriptome and proteome analyses of isolated DCTs demonstrated that CnB1 deletion impacts the expression of several DCT-specific proteins and signaling pathways. Thus, our data support a critical role of calcineurin for DCT function and provide novel insights into the pathophysiology of CNI side-effects and involved molecular players in the DCT.

The Association Between Psoriasis and Cardiovascular Diseases

Cardiovascular diseases and psoriasis have been well established as separate entities, however, there is uncertainty with regards to a link between the two diseases. A few environmental, psychological and social factors have been implicated as potential common risk factors that may exacerbate the two diseases, and an array of complex immune and non-immune inflammatory mediators can potentially explain a plausible link. Pharmacotherapy has also played a role in establishing a potential association, especially with the advent of biological agents which directly act on inflammatory factors shared by the two diseases. This review will look at existing evidence and ascertain a potential correlation between the two.

A novel protocol to assess the impact of prescription stimulants on blood pressure in adults using ambulatory blood pressure monitoring

Prescription stimulants are an important cause of secondary hypertension and their use is increasing in adult patients who are also at risk for essential hypertension. Although stimulants increase blood pressure, a systematic approach for assessing their impact in individual patients is lacking. We developed a protocol using ambulatory blood pressure monitoring for up to 36 h to compare blood pressure over two sequential days. Average blood pressure on the first day (without stimulant medication) was compared to average blood pressure on the second day (after re‐starting stimulant medication). We describe the outcomes of this protocol for a case series of eleven adults. Patients demonstrated one of three outcomes: normal blood pressure on both days, hypertension on both days, or hypertension only on the day patients received their stimulant medications. This novel protocol provides valuable information on the blood pressure effects of stimulant medications and allows clinicians to make personalized decisions regarding treatment.

Hypertensive Cardiotoxicity in Cancer Treatment-Systematic Analysis of Adjunct, Conventional Chemotherapy, and Novel Therapies-Epidemiology, Incidence, and Pathophysiology

Cardiotoxicity is the umbrella term for cardiovascular side effects of cancer therapies. The most widely recognized phenotype is left ventricular dysfunction, but cardiotoxicity can manifest as arrhythmogenic, vascular, myocarditic and hypertensive toxicities. Hypertension has long been regarded as one of the most prevalent and modifiable cardiovascular risk factors in the general population, but its relevance during the cancer treatment journey may be underestimated. Hypertensive cardiotoxicity occurs de novo in a substantial proportion of treated cancer patients. The pathology is incompletely characterized—natriuresis and renin angiotensin system interactions play a role particularly in conventional treatments, but in novel therapies endothelial dysfunction and the interaction between the cancer and cardiac kinome are implicated. There exists a treatment paradox in that a significant hypertensive response not only mandates anti-hypertensive treatment, but in fact, in certain cancer treatment scenarios, hypertension is a predictor of cancer treatment efficacy and response. In this comprehensive review of over 80,000 patients, we explored the epidemiology, incidence, and mechanistic pathophysiology of hypertensive cardiotoxicity in adjunct, conventional chemotherapy, and novel cancer treatments. Conventional chemotherapy, adjunct treatments, and novel targeted therapies collectively caused new onset hypertension in 33–68% of treated patients. The incidence of hypertensive cardiotoxicity across twenty common novel therapies for any grade hypertension ranged from 4% (imatinib) to 68% (lenvatinib), and high grade 3 or 4 hypertension in <1% (imatinib) to 42% (lenvatinib). The weighted average effect was all-grade hypertension in 24% and grade 3 or 4 hypertension in 8%.

Psychiatric Medications and Hypertension

PURPOSE OF REVIEW

The purpose of this review is to provide an overview of psychiatric medications that impact blood pressure in adult patients either as a direct side effect or indirectly, via negative metabolic impact or interactions with other medications. In addition, pertinent interactions between psychiatric medications and antihypertensive agents will be discussed.

RECENT FINDINGS

Although the novel intranasal antidepressant, esketamine, has been shown to increase blood pressure shortly after dosing, treatment with antihypertensive medications is not typically required. In addition, no increase in serious adverse cardiac events was reported with this medication. The negative metabolic impact of antipsychotic medications has been shown to occur within the first month of treatment and necessitates early monitoring. When compared with the general population with cardiovascular disease, mortality risk in patients with severe and persistent psychiatric illness is higher, and death occurs 10 years earlier. There are several psychiatric treatments that increase blood pressure directly as well as indirectly, via negative metabolic impact and drug/diet interactions. Fortunately, there are no absolute contraindications for use of any psychiatric medication in patients with pre-existing hypertension. Given data which suggests that patients diagnosed with more severe psychiatric disorders are known to receive inadequate medical care for hypertensive illness and experience increased mortality risk from cardiovascular disease, it is important for all physicians to be aware of the increased risk in this population and for both thorough assessment and treatment to occur.
