Abstract
Orthostatic intolerance is a broad term that represents a spectrum of dysautonomic disorders, including postural orthostatic tachycardia syndrome (POTS) and orthostatic hypotension (OH), as manifestations of severe autonomic failure. While the etiology of orthostatic intolerance has not yet fully been uncovered, it has been associated with multiple underlying pathological processes, including peripheral neuropathy, altered renin-aldosterone levels, hypovolemia, and autoimmune processes. Studies have implicated adrenergic, cholinergic, and angiotensin II type I autoantibodies in the pathogenesis of orthostatic intolerance. Several case series have demonstrated that immunomodulation therapy resulted in favorable outcomes, improving autonomic symptoms in POTS and OH. In this review, we highlight the contemporary literature detailing the association of autoimmunity with POTS and OH.

Abstract
Serotonin syndrome (SS) is a drug-induced clinical syndrome characterised by a combination of cognitive, neuromuscular and autonomic dysfunctions. The symptoms may include mild non-specific symptoms such as tremors and diarrhoea to coma and sudden death. Herein, we describe a case of SS in which acute dizziness was associated with supine hypertension and orthostatic hypotension. A man in his mid-30s had a 10-month history of anxiety, depression and chronic tension-type headache. He had been on amitriptyline (25 mg daily) and sertraline (50 mg daily). Increment of sertraline (75 mg daily) and amitriptyline (75 mg daily) and the addition of tramadol led to the development of acute severe dizziness. Physical examinations demonstrate supine hypertension and orthostatic hypotension. He also met the diagnostic criteria of SS. The administration of cyproheptadine provided a complete response to dizziness, supine hypertension, orthostatic hypotension and other clinical features of SS.

Shadmand M, Elliott B, Lautze J, Mehdirad A. A retrospective analysis of neurogenic orthostatic hypotension in long-term care facility residents with recurrent falls. Auton Neurosci 2024; 251:103135. [PMID: 38065033 DOI: 10.1016/j.autneu.2023.103135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 11/08/2023] [Accepted: 11/30/2023] [Indexed: 01/23/2024]
Abstract
INTRODUCTION Approximately 50 % of residents in long-term care facilities fall yearly and orthostatic hypotension accounts for a significant portion of them. Neurogenic orthostatic hypotension - a subtype of orthostatic hypotension - is important to be recognized as its management is far more complex; undertreatment of these older adults can lead to recurrent falls, high healthcare cost burden, and increased morbidity and mortality. The primary purpose of our study was to describe the rate of neurogenic orthostatic hypotension in older adults in a long-term care facility, with a secondary purpose to describe risk factors for neurogenic orthostatic hypotension in this population. METHODS We conducted a retrospective case-control study of residents with recurrent falls at the Dayton Veteran's Affairs long-term care facility. Charts were manually reviewed. Inclusion criterion was three or more falls and age 65 or greater; we did not have exclusion criteria. ICD10 codes and most recent primary care physician notes were used to identify comorbidity diagnoses. Recent orthostatic vitals were used to assess orthostatic hypotension or neurogenic orthostatic hypotension diagnoses. RESULTS Of our sample of 224 residents, we observed a prevalence of 20.5 % for neurogenic orthostatic hypotension and 32.1 % for orthostatic hypotension. Neither of them had diagnosis of neurogenic orthostatic hypotension documented. Parkinson's disease was associated with neurogenic orthostatic hypotension (OR-4.3; p = 0.002). Hypertension was prevalent in 69.6 % of residents with orthostatic vitals suggestive of neurogenic orthostatic hypotension. CONCLUSION Older adults with recurrent falls at a long-term care facility meet criteria for neurogenic orthostatic hypotension diagnosis far more often than is documented. Common comorbidities associated with neurogenic orthostatic hypotension in this population include Parkinson's disease.

Abstract
Multiple system atrophy (MSA) is a sporadic, fatal, and rapidly progressive neurodegenerative disease of unknown etiology that is clinically characterized by autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs in any combination. Early onset and extensive autonomic dysfunction, including cardiovascular dysfunction characterized by orthostatic hypotension (OH) and supine hypertension, urinary dysfunction characterized by overactive bladder and incomplete bladder emptying, sexual dysfunction characterized by sexual desire deficiency and erectile dysfunction, and gastrointestinal dysfunction characterized by delayed gastric emptying and constipation, are the main features of MSA. Autonomic dysfunction greatly reduces quality of life and increases mortality. Therefore, early diagnosis and intervention are urgently needed to benefit MSA patients. In this review, we aim to discuss the systematic treatment of autonomic dysfunction in MSA, and focus on the current methods, starting from non-pharmacological methods, such as patient education, psychotherapy, diet change, surgery, and neuromodulation, to various drug treatments targeting autonomic nerve and its projection fibers. In addition, we also draw attention to the interactions among various treatments, and introduce novel methods proposed in recent years, such as gene therapy, stem cell therapy, and neural prosthesis implantation. Furthermore, we elaborate on the specific targets and mechanisms of action of various drugs. We would like to call for large-scale research to determine the efficacy of these methods in the future. Finally, we point out that studies on the pathogenesis of MSA and pathophysiological mechanisms of various autonomic dysfunction would also contribute to the development of new promising treatments and concepts.

Abstract
In Parkinson's disease (PD), cardiovascular dysautonomia accumulates with disease progression, but studies are lacking on the natural history behind each subtype except orthostatic hypotension. This study investigated the early natural history of orthostatic blood pressure (BP) subtypes in PD. Two hundred sixty-seven early PD patients were included. Their cardiovascular functions were assessed by head-up tilt-test and 123I-metaiodobenzylguanidine scintigraphy. All patients were classified as having supine hypertension (SH), orthostatic hypertension (OHT), delayed orthostatic hypotension (dOH), or orthostatic hypotension (OH) according to consensus criteria. The patients were assigned to one of three groups: extreme BP dysregulation (BPextreme), mild BP dysregulation (BPmild), and no BP dysregulation (BPnone) according to their orthostatic BP subtypes. The autonomic functions of 237 patients were re-assessed after approximately 3 years. Among initially enrolled subjects, 61.8% of the patients showed orthostatic BP dysregulation: 29.6% in the BPextreme group and 32.2% in the BPmild group. At follow-up, the BPextreme group increased in number, while the BPmild group diminished. Two-thirds of the initial BPextreme patients maintained their initial subtype at follow-up. In comparison, 40.7% of the initial BPmild patients progressed to the BPextreme group, and 32.4% and 14.7% of the initial BPnone group progressed to BPextreme and BPmild groups, respectively. Cardiac denervation was most severe in the BPextreme group, and a linear gradient of impairment was observed across the subtypes. In conclusion, various forms of positional BP dysregulation were observed during the early disease stage. SH and OH increased with disease progression, while OHT and dOH decreased, converting primarily to SH and/or OH.

Abstract
Abstract The autonomic nervous system (ANS) is a complex network of nerves originating in the brain, brain stem, spinal cord, heart and extracardiac organs that regulates neural and physiological responses to internal and external environments and conditions. A common observation among patients with the 2019 Coronavirus (CoV) (SARS-severe acute respiratory syndrome CoV-2) (SARS-CoV-2) or COVID-19 [CO for corona, VI for virus, D for disease and 19 for when the outbreak was first identified (31 December 2019)] in the acute and chronic phases of the disease is tachycardia, labile blood pressure, muscular fatigue and shortness of breath. Because abnormalities in the ANS can contribute to each of these symptoms, herein a review of autonomic dysfunction in SARS-COV-2 infection is provided to guide diagnostic testing, patient care and research initiatives. Graphic abstract The autonomic nervous system is a complex network of nerves originating in the brain, brain stem, spinal cord, heart and extracardiac organs that regulates neural and physiological responses to internal and external environments and conditions. A common collection of signs and symptoms among patients with the 2019 Coronavirus (CoV) (SARS-severe acute respiratory syndrome CoV-2) (SARS-CoV-2) or COVID-19 [CO for corona, VI for virus, D for disease and 19 for when the outbreak was first identified (31 December 2019)] is tachycardia, labile blood pressure, muscular fatigue and shortness of breath. Abnormalities in the autonomic nervous system (ANS) can contribute to each of these identifiers, potentially offering a unifying pathobiology for acute, subacute and the long-term sequelae of SARS-CoV-2 infection (PASC) and a target for intervention.
