Abstract
Hypertension and diabetes mellitus (DM) are two of the leading lifestyle diseases in the Indian and South Asian populations that often co-exist due to overlapping pathophysiological factors. Obesity, insulin resistance, inflammation, and oxidative stress are thought to be some common pathways. Up to 50% of hypertensive cases in India are diagnosed with type 2 diabetes mellitus (T2DM), which defines the need for a comprehensive guideline for managing hypertension in diabetic patients. These RSSDI guidelines have been formulated based on consultation with expert endocrinologists in India and Southeast Asia, acknowledging the needs of the Indian population. Ambulatory blood pressure monitoring and office and home-based blood pressure (BP) monitoring are recommended for the early analysis of risks. Cardiovascular risks, end-organ damage, and renal disorders are the primary complications associated with diabetic hypertension that needs to be managed with the help of non-pharmacological and pharmacological interventions. The non-pharmacological interventions include the nutrition education of the patient to reduce the intake of salt, sodium, and trans fats and increase the consumption of nuts, fresh fruits, vegetables, and potassium-rich foods. It is also recommended to initiate 50 to 60 min of exercise three to four times a week since physical activity has shown to be more beneficial for hypertension control in Indian patients than dietary modulation. For the pharmacological management of hypertension in patients with T2DM, angiotensin II receptor blockers (ARBs) are recommended as the first line of therapy, demonstrating their superiority over other antihypertensive agents such as ACEi. However, most of the global hypertension guidelines recommend initiation with combination therapy to achieve better BP control in most patients and to reduce the risk of adverse events. For combination therapy, calcium channel blockers (CCBs) are recommended to be administered along with ARBs instead of beta-blockers or diuretics to avoid the risk of cardiovascular events and hyperglycaemia. Among the CCBs, novel molecules (e.g. cilnidipine) are recommended in combination with ARBs for better cardiovascular and reno-protection in diabetic hypertensive patients.

Abstract
Resistant hypertension (RH) is characterized by the use of three or more antihypertensive drugs without reaching the goal of controlling blood pressure (BP). For a definitive diagnosis of RH, it is necessary to exclude causes of pseudoresistance, including the white-coat effect, errors in BP measurement, secondary hypertension, therapeutic inertia, and poor adherence to lifestyle changes and pharmacological treatment. Herein, we report the history of a patient with long-standing uncontrolled BP, even when using seven antihypertensive drugs. Causes of secondary hypertension that justified the high BP levels were investigated, in addition to the other causes of pseudo-RH. In view of the difficult-to-control BP situation, it was decided to hospitalize the patient for better investigation. After 5 days, he had BP control with practically the same medications previously used. Finally, all factors related to the presence of pseudo-RH are discussed, especially poor adherence to treatment. Poor adherence to antihypertensive treatment is common in daily medical practice, and its investigation is of fundamental importance for better management of BP.

Abstract
The prognostic importances of on-treatment clinic and ambulatory blood pressure (BP) levels have never been investigated in individuals with resistant hypertension. We aimed to evaluate them for the occurrence of incident cardiovascular and mortality outcomes in a prospective cohort of 1726 patients with resistant hypertension. Clinic and ambulatory BPs were measured at baseline and serially during follow-up (analyzed as time-varying and as mean cumulative BPs) and also categorized as controlled/uncontrolled as defined by the traditional and new 2017 American College of Cardiology/American Heart Association criteria. Multivariate Cox analyses examined the associations between BP parameters and the occurrence of total cardiovascular events, major adverse cardiovascular events, and cardiovascular and all-cause mortalities. C statistics and the integrated discrimination improvement indexes evaluated the improvement in risk discrimination. Over a median follow-up of 8.3 years, 417 total cardiovascular events occurred (358 major adverse cardiovascular events) and 391 individuals died (233 cardiovascular deaths). All single systolic BP (SBP) parameters significantly predicted all outcomes, but the associations were stronger for ambulatory SBPs than for clinic SBPs and for on-treatment SBPs (particularly for mean cumulative) than for baseline SBPs, and both improved risk discrimination (with increases in C statistic of up to 0.021 and integrated discrimination improvements of up to 19.7%). These findings were consistent for diastolic BPs. Uncontrolled ambulatory BPs were associated with higher risks for all outcomes, whereas uncontrolled clinic BPs were not. In conclusion, mean cumulative ambulatory BPs during follow-up were the best prognostic markers of adverse cardiovascular outcomes and mortality in patients with resistant hypertension. Serial ambulatory BP monitoring shall be more widely used in resistant hypertension management.

Abstract
Refractory hypertension (RfH) is an extreme phenotype of resistant hypertension
(RH), being considered an uncontrolled blood pressure besides the use of 5 or
more antihypertensive medications, including a long-acting thiazide diuretic and
a mineralocorticoid antagonist. RH is common, with 10-20% of the general
hypertensives, and its associated with renin angiotensin aldosterone system
hyperactivity and excess fluid retention. RfH comprises 5-8% of the RH and seems
to be influenced by increased sympathetic activity. RH patients are older and
more obese than general hypertensives. It is strongly associated with diabetes,
obstructive sleep apnea, and hyperaldosteronism status. RfH is more frequent in
women, younger patients and Afro-americans compared to RFs. Both are associated
with increased albuminuria, left ventricular hypertrophy, chronic kidney
diseases, stroke, and cardiovascular diseases. The magnitude of the white-coat
effect seems to be higher among RH patients. Intensification of diuretic therapy
is indicated in RH, while in RfH, therapy failure imposes new treatment
alternatives such as the use of sympatholytic therapies. In conclusion, both RH
and RfH constitute challenges in clinical practice and should be addressed as
distinct clinical entities by trained professionals who are capable to identify
comorbidities and provide specific, diversified, and individualized
treatment.

Abstract
INTRODUCTION Despite type 2 diabetes (T2D) management offers a variety of pharmacological interventions targeting different defects, numerous patients remain with persistent hyperglycaemia responsible for severe complications. Unlike resistant hypertension, treatment resistant T2D is not a classical concept although it is a rather common observation in clinical practice. Areas covered: This article proposes a definition for 'treatment resistant diabetes', analyses the causes of poor glucose control despite standard therapy, briefly considers the alternative approaches to glucose-lowering pharmacotherapy and finally describes how to overcome poor glycaemic control, using innovative oral or injectable combination therapies. Expert opinion: Before considering intensifying the pharmacotherapy of a patient with poorly controlled T2D, it is important to verify treatment adherence, target obesity and consider various non pharmacological improvement quality interventions. If treatment resistant diabetes is defined as not achieving glycated haemoglobin target despite oral triple therapy with a third glucose-lowering agent added to metformin-sulfonylurea dual treatment, the combination of a dipeptidyl peptidase-4 (DPP-4) inhibitor and a sodium glucose cotransporter type 2 (SGLT2) inhibitor may offer new opportunities before considering injectable therapies. Insulin basal therapy (± metformin) may be optimized by the addition of a SGLT2 inhibitor or a glucagon-like peptide-1 (GLP-1) receptor agonist.

Abstract
The authors previously demonstrated that acute administration of sildenafil-a phosphodiesterase 5 (PDE5) inhibitor-improves hemodynamic parameters in patients with resistant hypertensive (RH), but its effect on ambulatory blood pressure monitoring (ABPM) is unknown. This interventional, nonrandomized, single-blinded, placebo-controlled, crossover trial included 26 patients with RH. A dose of sildenafil (187.5mg) was given, and after a washout period of 14 days the patients received a single oral dose of placebo and the protocol was repeated. The patients underwent 24-hour ABPM recordings the day before and immediately after the protocols. The reduction of systolic (-8.8±1.4 vs 1.3±1.2 mm Hg, P=.02), diastolic (-5.3±3.3 vs 1.8±1.1 mm Hg, P=.03), and mean (-7.9±3.6 vs 0.8±0.9 mm Hg, P=.01) 24-hour BP were found after the use of sildenafil compared with placebo. Improvement in daytime BP levels was also observed (systolic -6.0±4.7 vs 4.4±1.5 mm Hg [P=.02] and mean -4.8±3.9 vs 3.5±1.4 mm Hg [P=.02] for sildenafil vs placebo, respectively). Considering its antihypertensive effect, sildenafil may represent a therapeutic option for RH treatment.

Abstract
More than 80 million Americans have hypertension (HTN), and African Americans (AAs) are disproportionately affected. AAs also have lower rates of adherence to HTN treatment. It is important to understand AAs' perceptions of adherence to develop effective interventions. The aim of this study is to examine AAs' perceptions of adherence to medications and lifestyle changes prescribed to treat HTN. In this qualitative study, we used purposive sampling to recruit Southern AAs with HTN aged 21 and older from a free, faith-based clinic. We recorded individual, in-person interviews about perceptions related to adherence to treatment of HTN and analyzed verbatim transcripts using content analysis and constant comparison. We also conducted medical record audits. Twenty-nine AAs participated (52% female, 38% were <50 years of age, 52% had taken anti-HTN medications for ≥5 years). Audits indicated that 65% had uncontrolled HTN during the previous year. Two main themes included causes of HTN and ways to improve blood pressure. Perceived causes of HTN included diet, stress, unhealthy actions, genes, and obesity. Ways to improve HTN included using cultural treatments "passed down," increasing exercise, reducing stress, and losing weight. Many reported using home remedies to control HTN, including drinking pickle juice. More than half of this sample had uncontrolled HTN. They identified influences of culture on perceptions of adherence including causes and treatment of HTN, and possibly detrimental home remedies. It is imperative that clinicians identify culturally appropriate interventions for this high-risk group.

Abstract
With an increased prevalence, resistant hypertension is recognized as an entity with a high cardiovascular morbidity and mortality. In a large cohort of patients with resistant hypertension, the crude incidence rate of total cardiovascular events reached 4.32 per 100 patient-years of follow-up (19.6 %), with a cardiovascular mortality of 8.3 % (incidence rate of 1.72 per 100 patient-years). Cardiovascular event rates are significantly higher in resistant hypertensives compared with non-resistant (18.0 % versus 13.5 %). In the same way, the prevalence of established cardiovascular and renal disease, as the asymptomatic organ damage (represented by left ventricular hypertrophy, carotid wall thickening, arterial stiffness, and microalbuminuria) is higher in these patients. Many studies have demonstrated a strong association between damage to these organs with higher blood pressure levels, the diagnosis of true resistant hypertension, and refractory hypertension. All efforts should be employed in order to control blood pressure and also to regress and/or prevent subclinical cardiovascular and renal damage. The focus should be on prevention of cardiovascular and renal complications, improving the prognosis of resistant hypertension.

Abstract
AIM Hydralazine, a vasodilator used in resistant hypertension (RH) treatment is metabolized by an acetylation reaction mediated by N-acetyltransferase 2, the activity of which depends on NAT2 polymorphisms. Our aim was to evaluate whether different acetylation phenotypes influenced the antihypertensive effect of hydralazine in patients with RH. PATIENTS & METHODS DNA samples from 169 RH patients using hydralazine were genotyped by sequencing the NAT2 coding region, and acetylation phenotypes were defined. RESULTS Sixty-five patients (38.5%) were intermediate, 60 (35.5%) slow and 21 (12.4%) fast acetylators. Twenty-three (13.6%) patients were indeterminate. Upon association analysis, only slow acetylators had significant blood pressure reductions after hydralazine use, with mean 24-h systolic and diastolic blood pressure reductions of 9.2 and 5.5 mmHg. Four patients presented hydralazine adverse effects resulting in drug withdrawal, three of them were slow acetylators. CONCLUSION The slow acetylation phenotype, determined by polymorphisms within NAT2, influenced both the antihypertensive and adverse effects of hydralazine in RH.

Abstract
BACKGROUND Ambulatory blood pressure (BP) monitoring (ABPM) is a cornerstone in resistant hypertension (RHT) management. However, it has higher cost and lower patients' acceptance than home BP monitoring (HBPM). Our objective was to evaluate HBPM usefulness in the management of patients with RHT. METHODS A total of 240 patients were submitted to 24-hour ABPM and 5-day HBPM (triplicate morning and evening measurements). Patients with uncontrolled office BP (≥140/90mm Hg) were classified as true RHT (daytime or home BP ≥135/85mm Hg) or white-coat RHT (daytime or home BP <135/85mm Hg), and patients with controlled office BP were classified as masked RHT (daytime or home BP ≥135/85mm Hg) or controlled RHT (daytime or home BP <135/85mm Hg). Sensitivity, specificity, predictive values, and likelihood ratios for HBPM were calculated. Agreement between the procedures was evaluated using kappa coefficients and the Bland-Altman method. RESULTS Mean office BP was 157±26/84±16mm Hg, mean daytime BP was 134±18/77±13mm Hg, and mean home BP was 143±20/76±14mm Hg. The ABPM and HBPM diagnoses were 35% and 48%, respectively, for true RHT; 36% and 23%, respectively, for white-coat RHT; 7% and 17%, respectively, for masked RHT; and 22% and 13%, respectively, for controlled RHT. HBPM overestimated systolic BP by 8.8 (95% confidence interval (CI) = 6.8-10.7) mm Hg and diastolic BP by 0.2 (95% CI = -1.0 to 1.4) mm Hg. The specificity, sensitivity, and positive and negative predictive values of HBPM in detecting controlled ambulatory BP were 91%, 55%, 89%, and 59%. CONCLUSIONS HBPM presented good agreement with ABPM and can be used as a complementary method in the follow-up of resistant hypertensive patients, particularly in those with controlled ambulatory BPs.

Abstract
The effect of continuous positive airway pressure (CPAP) on blood pressures (BPs) in patients with resistant hypertension and obstructive sleep apnea is not established. We aimed to evaluate it in a randomized controlled clinical trial, with blinded assessment of outcomes. Four hundred thirty-four resistant hypertensive patients were screened and 117 patients with moderate/severe obstructive sleep apnea, defined by an apnea-hypopnea index ≥15 per hour, were randomized to 6-month CPAP treatment (57 patients) or no therapy (60 patients), while maintaining antihypertensive treatment. Clinic and 24-hour ambulatory BPs were obtained before and after 6-month treatment. Primary outcomes were changes in clinic and ambulatory BPs and in nocturnal BP fall patterns. Intention-to-treat and per-protocol (limited to those with uncontrolled ambulatory BPs) analyses were performed. Patients had mean (SD) 24-hour BP of 129(16)/75(12) mm Hg, and 59% had uncontrolled ambulatory BPs. Mean apnea-hypopnea index was 41 per hour and 58.5% had severe obstructive sleep apnea. On intention-to-treat analysis, there was no significant difference in any BP change, neither in nocturnal BP fall, between CPAP and control groups. The best effect of CPAP was on night-time systolic blood pressure in per-protocol analysis, with greater reduction of 4.7 mm Hg (95% confidence interval, -11.3 to +3.1 mm Hg; P=0.24) and an increase in nocturnal BP fall of 2.2% (95% confidence interval, -1.6% to +5.8%; P=0.25), in comparison with control group. In conclusion, CPAP treatment had no significant effect on clinic and ambulatory BPs in patients with resistant hypertension and moderate/severe obstructive sleep apnea, although a beneficial effect on night-time systolic blood pressure and on nocturnal BP fall might exist in patients with uncontrolled ambulatory BP levels.

Abstract
Severe hypertension (systolic blood pressure (BP) ⩾160 mm Hg) resistant to treatment with multiple antihypertensive medications, poses a serious challenge to therapeutic treatment. Catheter-based renal denervation (RDN) is being increasingly proposed and researched as a safe and effective method of treating this condition. This article evaluates the existing evidence on the effects of RDN on BP reduction and other conditions with increased sympathetic tone. Findings indicate that RDN is a safe and effective treatment for severe hypertension. Moreover, the antihypertensive response to RDN is sustained for up to 3 years of follow-up. RDN decreases office BP more than ambulatory BP, which may be explained by the white-coat effect that causes an increase in office BP. Findings indicate that although reinnervation may occur following RDN, it does not appear to attenuate or reverse the BP response over 24-36 months. There is also evidence that patients with milder forms of hypertension may benefit from RDN. Furthermore, there is emerging evidence that RDN may have a role in the treatment of heart failure, obstructive sleep apnea, insulin resistance, atrial fibrillation and hypertension associated with end-stage renal disease. Taking into account that resistant hypertension and other diseases associated with elevated sympathetic tone are associated with significant morbidity and mortality rates, RDN therapy may be expected to have a significant impact on public health.
