Laura E Levin, Cynthia Magro, James Horowitz, Joanna Harp
Hydralazine-induced small vessel vasculitis is a rare entity with a limited number of cases reported in the dermatologic literature. A characteristic pattern of acral pseudoembolic vesiculopustules with necrosis and ulceration has been suggested along with involvement of the aerodigestive tract, indicating mucosal involvement is an important feature of this disease. We report the case of a patient with hydralazine-induced vasculitis who exemplified this characteristic presentation associated with severe involvement of the aerodigestive tract and gastrointestinal tract bleeding...

Wilbert S Aronow
Heart failure (HF) with abnormal left ventricular (LV) ejection fraction should be identified and treated. Treat hypertension with diuretics, angiotensin-converting enzyme (ACE) inhibitors, and β-blockers. Treat myocardial ischemia with nitrates and β-blockers. Treat volume overload and HF with diuretics. Treat HF with ACE inhibitors and β-blockers. Sacubitril/valsartan may be used instead of an ACE inhibitor or ARB in chronic symptomatic HF and abnormal LV ejection fraction. Add isosorbide dinitrate/hydralazine in African Americans with class II to IV HF treated with diuretics, ACE inhibitors, and β-blockers...

Diabetes-induced neuropathic pain (DNP) substantially influences people's life qualities. Hyperglycemia-induced excess free radicals have been considered as the most critical mechanisms underlying DNP. As an unsaturated aldehyde and a reactive product of lipid peroxidation, acrolein plays critical roles in diabetic nephropathy and inflammatory pain. We sought to determine whether acrolein is involved in DNP in the present study. Diabetes was induced by a single intraperitoneal (i.p.) injection of 60 mg/kg streptozotocin (STZ)...

The Interagency Emergency Health Kit (IEHK) provides a standard package of medicines and simple medical devices for aid agencies to use in emergencies such as disasters and armed conflicts. Despite the increasing burden of non-communicable diseases (NCDs) in such settings, the IEHK includes few drugs and devices for management of NCDs. Using published data to model the population burden of acute and chronic presentations of NCDs in emergency-prone regions, we estimated the quantity of medications and devices that should be included in the IEHK...

REVIEW
Margaret-Ann M Nelson, Shahid P Baba, Ethan J Andersonc
Aldehydes are continuously formed in biological systems through enzyme-dependent and spontaneous oxidation of lipids, glucose, and primary amines. These highly reactive, biogenic electrophiles can become toxic via covalent modification of proteins, lipids and DNA. Thus, agents that scavenge aldehydes through conjugation have therapeutic value for a number of major cardiovascular diseases. Several commonly-prescribed drugs (e.g., hydralazine) have been shown to have potent aldehyde-conjugating properties which may contribute to their beneficial effects...

This study investigated the influence of sodium restriction and antihypertensive drugs on atherogenesis utilizing hypertensive (H) low-density lipoprotein-receptor knockout mice treated or not with losartan (Los) or hydralazine (Hyd) and fed low-sodium (LS) or normal-sodium (NS) chow. Despite reducing the blood pressure (BP) of H-LS mice, the LS diet caused arterial lipid infiltration due to increased plasma total cholesterol (TC) and triglycerides (TG). Los and Hyd reduced the BP of H-LS mice, and Los effectively prevented arterial injury, likely by reducing plasma TG and nonesterified fatty acids...

The neovascularization of atherosclerotic lesions is involved in plaque development and may contribute to intraplaque hemorrhage and plaque fragilization and rupture. Among the various proangiogenic agents involved in the neovascularization process, proatherogenic oxidized LDLs (oxLDLs) contribute to the formation of tubes via the generation of sphingosine 1-phosphate (S1P), a major mitogenic and proangiogenic sphingolipid mediator. In this study, we investigated whether 4-hydroxynonenal (4-HNE), an aldehydic lipid oxidation product abundantly present in oxLDLs, contributes to their proangiogenic properties...

Increased blood pressure variability has been shown to be associated with cardiovascular morbidity and mortality. Recently we reported that continuous infusion of angiotensin II not only elevated blood pressure level, but also increased blood pressure variability in a manner assumed to be independent of blood pressure elevation in rats. In the present study, the effects of the angiotensin type I receptor blocker losartan and the calcium channel blocker azelnidipine on angiotensin II-induced blood pressure variability were examined and compared with that of the vasodilator hydralazine in rats...

BACKGROUND: Left ventricular hypertrophy (LVH) secondary to hypertension has been accepted to prevent heart failure (HF) while paradoxically increasing cardiovascular morbi-mortality. OBJECTIVES: To evaluate whether antihypertensive treatment inhibits LVH, restores beta-adrenergic response and affects myocardial oxidative metabolism. METHODS: Ninety spontaneously hypertensive rats (SHR) were distributed into groups and treated (mg/kg, p.o...

Pre-eclampsia (PE) is defined as pregnancy-induced hypertension and proteinuria, and is a major cause of maternal and perinatal morbidity and mortality. A large subgroup of pregnant women with PE is nonresponsive to antihypertensive drugs, including methyldopa, nifedipine and hydralazine. Pharmacogenomics may help to guide the individualized therapy for this nonresponsive subgroup. However, just a few pharmacogenetic studies examined the effects of genetic polymorphisms on response to antihypertensive drugs in PE, and the criteria of responsiveness used to define responsive or nonresponsive subgroups to antihypertensive therapy should be replicated by others...

Endothelin 1 (ET-1), a potent vasoconstrictor, pro-mitogenic and pro-inflammatory peptide, may promote development of endothelial dysfunction and arterial remodeling. ET-1 can be formed through cleavage of big-ET-1 by endothelin-converting enzyme (ECE) or neutral endopeptidase (NEP). We investigated whether chronic treatment with the novel dual NEP/ECE inhibitor SOL1 improves functional and structural properties of resistance-sized arteries of 32-week-old male spontaneously hypertensive rats (SHR). SHR received a chronic 4-week treatment with SOL1, losartan or hydralazine...

Previous studies have demonstrated that a range of stimuli activate neurons, including catecholaminergic neurons, in the ventrolateral medulla. Not all catecholaminergic neurons are activated and other neurochemical content is largely unknown hence whether stimulus specific populations exist is unclear. Here we determine the neurochemistry (using in situ hybridization) of catecholaminergic and noncatecholaminergic neurons which express c-Fos immunoreactivity throughout the rostrocaudal extent of the ventrolateral medulla, in Sprague Dawley rats treated with hydralazine or saline...

This study investigated the effect of epinephrine (a vasoconstrictor) and hydralazine (a vasodilator) on the hepatic disposition of 5-fluorouracil (5-FU) after application to the surface of the liver in rats. Normal livers were compared with a Walker 256 carcinoma cell tumor model. A cylindrical diffusion cell was attached to the liver surface. 5-Fluorouracil was added into the diffusion cell in combination with vasomodulators or after pretreatment with epinephrine. After selected treatment times, the 5-FU concentrations were assayed at three sites in the excised livers...

BACKGROUND: Hydralazine-nitrate combination is recommended for patients with heart failure with reduced ejection fraction (HFrEF)/systolic heart failure who are symptomatic despite guideline-directed medical therapy (GDMT). Use of nitrates alone for this indication is not well-established. This study aims to evaluate the effect of oral nitrates on all-cause mortality and hospitalization in HFrEF patients using GDMT. METHODS AND RESULTS: Nitrate prescription at discharge and its association with all-cause mortality and heart failure hospitalization were examined in a propensity-matched analysis of 648 HFrEF patients followed for a median of 56 months...
