"Hypertensive emergency"

BACKGROUND: Increased neuroinflammation in brain regions regulating sympathetic nerves is associated with hypertension. Emerging evidence from both human and animal studies suggests a link between hypertension and gut microbiota, as well as microbiota-derived metabolites short-chain fatty acids (SCFAs). However, the precise mechanisms underlying this gut-brain axis remain unclear. METHODS: The levels of microbiota-derived SCFAs in spontaneously hypertensive rats (SHRs) were determined by gas chromatography-mass spectrometry...

Resistant hypertension (RHT) is characterized by persistently high blood pressure (BP) levels above the widely recommended therapeutic targets of less than 140/90 mmHg office BP, despite life-style measures and optimal medical therapies, including at least three antihypertensive drug classes at maximum tolerated dose (one should be a diuretic). This condition is strongly related to hypertension-mediated organ damage and, mostly, high risk of hospitalization due to hypertension emergencies or acute cardiovascular events...

Portal hypertension (PH) is a complex clinical challenge with severe complications, including variceal bleeding, ascites, hepatic encephalopathy, and hepatorenal syndrome. The gut microbiota (GM) and its interconnectedness with human health have emerged as a captivating field of research. This review explores the intricate connections between the gut and the liver, aiming to elucidate how alterations in GM, intestinal barrier function, and gut-derived molecules impact the development and progression of PH. A systematic literature search, following PRISMA guidelines, identified 12 original articles that suggest a relationship between GM, the gut-liver axis, and PH...

Thrombotic microangiopathy (TMA) is associated with both hypertensive emergency and primary thrombocytopenia purpura (TTP). However, their clinical management is vastly different, with the latter necessitating urgent plasma exchange (PEX). We report two cases of hypertension-associated TMA (HTN-TMA) and a literature review of the clinical management of malignant hypertension. We suggest that in patients presenting with hypertensive emergency associated with TMA, a clinical diagnosis of HTN-TMA should be made, with emergent treatment to lower blood pressure started immediately...

Nuclear factor kappa B (NF-κB) family plays a central role in the human immune system. Heterozygous variants in NFKB2 typically cause immunodeficiency with various degrees of central adrenal insufficiency, autoimmunity, and ectodermal dysplasia. No reported case has presented kidney failure as an initial symptom. Moreover, documentation of kidney involvement of this disease is limited. CASE DIAGNOSIS: A 2-year-old female who presented with dyspnea and hypertensive emergency in the setting of new-onset nephrotic syndrome with acute-on chronic kidney injury with resultant chronic kidney disease (CKD) was found to have a novel heterozygous N-terminal variant in NFKB2 (c...

BACKGROUND: Management of elevated blood pressure (BP) during hospitalization varies widely, with many hospitalized adults experiencing BPs higher than those recommended for the outpatient setting. PURPOSE: To systematically identify guidelines on elevated BP management in the hospital. DATA SOURCES: MEDLINE, Guidelines International Network, and specialty society websites from 1 January 2010 to 29 January 2024. STUDY SELECTION: Clinical practice guidelines pertaining to BP management for the adult and older adult populations in ambulatory, emergency department, and inpatient settings...

BACKGROUND: Hypertension (HTN) is common in discharged emergency department (ED) patients, yet the short-term outcomes of treating HTN at ED discharge are unclear. This study aimed to investigate whether emergency physician (EP) prescription of oral antihypertensive therapy at ED discharge for hypertensive patients is associated with a decreased 30-day risk of the severe adverse events (AEs), death, and revisits to the ED. METHODS: We conducted an observational cohort study assessing the 30-day outcomes of discharged ED patients with HTN, comparing outcomes based on whether antihypertensive therapy was prescribed...

A 28-year-old woman with a 5-year history of untreated hypertension was admitted for respiratory distress, hemoptysis, and retinopathy. Computed tomography showed diffuse plaques in both lung fields. Acute kidney injury, hemolytic anemia, and thrombocytopenia were noted. Kidney biopsy showed thrombosis with fibrinoid necrosis and edematous intimal thickening and luminal narrowing of the small renal artery, indicating thrombotic microangiopathy; the majority of glomeruli were collapsed. After 8 weeks of treatment with antihypertensive drugs, serum creatinine decreased to 1...

The delayed onset of posttraumatic subdural hemorrhage (SDH) represents non-specific clinical features, complicating the diagnostic process, especially in individuals predisposed due to pre-existing risk factors and comorbidities. This case report delineates the medical trajectory of a 61-year-old female patient who sustained a traumatic fall, initially displaying neither clinical nor radiological signs indicative of hemorrhage. However, three weeks post-injury, she developed altered mental status, cephalgia, and emesis...

Tizanidine is commonly prescribed for muscle spasticity and pain. Yet, withdrawal is rarely reported. Tizanidine stimulates presynaptic α-2 adrenergic and imidazoline receptors decreasing norepinephrine release. Abrupt cessation can cause withdrawal. Current treatment strategies include tapering oral tizanidine or substituting oral clonidine. A 52-year-old male with a history of hypertension, diabetes, coronary artery disease, and chronic back pain presented with altered mental status, agitation, hypertensive emergency (blood pressure: 250/145 mmHg), and tachycardia...

Falls constitute a leading cause of unintentional injury deaths among older adults. This study aimed to examine the comprehensive characteristics of fatal falls among older individuals in Yunnan Province, China, to highlight the challenges faced in elderly care. A total of 22,798 accidental fall-related deaths were extracted from China's National Disease Surveillance Points System aged 60 and above between 2015 and 2019. Quantitative and textual data were analyzed to assess the incidence rates of initiating factors, locations, symptoms, and overall survival (OS) outcomes after falling...

We present the case of a patient with a history of renal-vascular hypertension treated with stent one year previously, who attended the emergency room due to hypertensive emergency and dyspnea. Once the first suspicion of renal artery restenosis was ruled out with CT angiography, the study was completed, confirming the diagnosis of lung cancer through imaging and pathological anatomy. In the hormonal study, elevation of ACTH, hypercortisolism and analytical data of hyperaldosteronism were detected. With the final diagnosis of Cushing's syndrome secondary to ectopic production of ACTH, medical treatment was started, without being able to receive anything else due to the death of the patient after a few days...

BACKGROUND: Erenumab is a monoclonal antibody that targets the calcitonin gene-related peptide (CGRP) receptor and is approved for the preventative treatment of migraine in adults. CGRP is involved in the regulation of vasomotor tone under physiologic and pathologic conditions, including hypertension. While there has not been evidence of hypertension in preclinical models or clinical trials, post-marketing data suggest erenumab may be associated with hypertension. This led to a warning in the United States Food and Drug Administration prescribing information for erenumab...

Individuals with depression face an elevated stroke risk, marked by an unfavorable prognosis. This meta-analysis aims to determine the impact of depression on stroke risk. The current meta-analysis was conducted using the guidelines established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We selected studies through a systematic review of electronic databases, including PubMed, EMBASE, and CINAHL from January 2011 to January 2023. Google Scholar was utilized to identify supplementary studies...

Cardiovascular pathology can complicate the course of COVID-19. The study aimed to identify echocardiographic abnormalities and key prognostic factors influencing severe and fatal COVID-19 outcomes. This retrospective cohort study included clinical and echocardiogram data from 194 medical records of hospitalized patients with COVID-19: 100 moderate cases, 34 severe cases with favorable outcomes, and 60 severe cases with fatal outcomes. Severe patients with favorable outcomes had greater reductions in left ventricular systolic fraction of left ventricle compared to moderate cases (23...

Atropine, a competitive antagonist of acetylcholine muscarinic receptors, is commonly used to treat severe bradycardia by blocking parasympathetic activity. We present a rare case of hypertensive emergency following atropine administration, with only one previous report in the literature. A 78-year-old woman with essential hypertension and hypercholesterolemia was admitted to the cardiac intensive care unit for non-ST segment elevation myocardial infarction. During coronary angiography, an occlusion of the right coronary artery was identified...

Posterior reversible encephalopathy syndrome is an emergency medical condition with varied causes presenting as reversible subcortical vasogenic brain edema caused by endothelial injury, resulting from changes in blood pressure or direct effects of cytokines on endothelium. Posterior reversible encephalopathy syndrome is manifested by neurologic symptoms. Common causes include hypertensive emergency, renal disease, preeclampsia, eclampsia, and immunosuppressive drugs. In this case report, a 17-year-old female patient on hemodialysis as a result of lupus nephritis who had previously undergone deceased donor organ transplant and was on triple immunosuppression presented with neurological symptoms of posterior reversible encephalopathy syndrome in the early posttransplant period...

Pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS) is a rare condition characterized by microangiopathic hemolytic anemia and kidney injury from thrombotic microangiopathy. P-aHUS occurs in approximately 1 in 25,000 pregnancies and is strongly related to complement dysregulation and pregnancy-related disorders, such as preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, low platelet (HELLP) syndrome, resulting in adverse perinatal and fetal outcomes. Complement dysregulation in P-aHUS is commonly attributed to genetic mutations or autoantibodies affecting complement factors, including CFH , CFI , and MCP...

BACKGROUND: Few certainties exist regarding optimal management of Blood Pressure (BP) in the very first hours after an ischemic stroke and many questions remain still unanswered. Our work aimed to evaluate the role of BP and its trend as possible determinants of in-hospital mortality (primary outcome), discharge disabilities and hospitalization length (secondary outcomes) in ischemic stroke patients presented with Hypertensive Emergencies (HE). METHODS: We retrospectively evaluated patients presented to Niguarda Hospital, Emergency Department (ED), from 2015 to 2017 with a neurological ischemic HE...
