Comparison of Covid-19 antibody status after vaccination between residents in long-term geriatric care and residents assisted-living facilities.

OBJECTIVE: To compare 2 CoV-SARS-2 ('anti-s') antibody levels after vaccination between residents in long-term geriatric care (LTGC) and residents in assisted-living facilities who had received two doses of the BNT162b2 vaccine. SARS-CoV-2 serology was tested with Quant II IgG CoV-SARS-2. Blood samples were collected 3-4 months after administration of the second vaccine dose. RESULTS: Anti-s ≥ 50 AU/ml was found in 85.4% of 90 residents in LTGC (median 498 AU/ml) and 94.9% of 214 residents in assisted living (median 728 AU/ml). p = .006. Factors associated with anti-s < 300 AU/ml were multi-morbidity, diabetes mellitus and cancer.

Cancer-Associated Atherothrombosis: The Challenge.

The association between venous thrombosis and malignancy, having typical features of a paraneoplastic syndrome, has been established for a century. Currently, it is recognized that arterial thromboembolism (ATE) may also behave as a paraneoplastic syndrome. Recent matched cohort studies, systematic reviews, and observational studies concur in showing an increased incidence of acute coronary events, ischemic stroke, accelerated peripheral arterial disease, and in-stent thrombosis during the 6-month period before cancer diagnosis, peaking for 30 days immediately before cancer diagnosis. Cancer patients with ATE are at higher risk of in-hospital and long-term mortality as compared with noncancer patients. In the present review, we focus on the epidemiology, clinical variants and presentation, morbidity, mortality, primary and secondary prevention, and treatment of cancer-associated ATE. The awareness that cancer can be a risk factor for ATE and that cancer therapy can initiate cardiovascular complications make it mandatory to identify high-risk patients, modify preexistent cardiovascular risk factors, and adopt effective antithrombotic prophylaxis. For ATE prophylaxis, modifiable patient-related risk factors and oncology treatment-related factors are levers for intervention. Statins and platelet antiaggregants have been studied, but their efficacy for prevention of cancer-associated ATE remains to be demonstrated. Results of revascularization procedures for cancer-associated ATE are worse than for ATE in noncancer patients. It is important that a multidisciplinary approach is adopted for making informed decisions, by involving the vascular surgeon, interventional radiologist, oncologist, and palliative medicine, as well as the patients and their family.

Blood pressure management in older people: balancing the risks.

Guidelines of arterial hypertension treatment based on individualised expected outcomes are not available for frail older persons. In this paper, we review the evidence, concerning management of arterial blood pressure (BP) in frail older patients. We focused on the best affordable methods for BP measurement; the age-related optimum BP; specific BP goals in agreement with the patients' general heath, frailty status, orthostatic and postprandial hypotension; balancing the benefits against risks of antihypertensive treatment. Lenient BP goals are generally recommended for older persons with moderate or severe frailty, multimorbidity and limited life expectancy. To this aim, there may be a need for deintensification of antihypertensive treatment.

Electrocardiographic QT interval and cardiovascular reactivity in fibromyalgia differ from chronic fatigue syndrome.

BACKGROUND: Fibromyalgia (FM) and chronic fatigue syndrome (CFS) frequently overlap clinically and have been considered variants of one common disorder. We have recently shown that CFS is associated with a short corrected electrocardiographic QT interval (QTc). In the present study, we evaluated whether FM and CFS can be distinguished by QTc. METHODS: The study groups were comprised of women with FM (n=30) and with CFS (n=28). The patients were evaluated with a 10 min supine-30 min head-up tilt test. The electrocardiographic QT interval was corrected for heart rate (HR) according to Fridericia's equation (QTc). In addition, cardiovascular reactivity was assessed based on blood pressure and HR changes and was expressed as the 'hemodynamic instability score' (HIS). RESULTS: The average supine QTc in FM was 417 ms (SD 25) versus 372 ms (SD 22) in CFS (p<0.0001); the supine QTc cut-off <385.7 ms was 79% sensitive and 87% specific for CFS vs. FM. The average QTc at the 10th minute of tilt was 409 ms (SD 18) in FM versus 367 ms (SD 21) in CFS (p<0.0001); the tilt QTc cut-off <383.3 ms was 71% sensitive and 91% specific for CFS vs. FM. The average HIS in FM patients was -3.52 (SD 1.96) versus +3.21 (SD 2.43) in CFS (p<0.0001). CONCLUSION: A relatively short QTc and positive HIS characterize CFS patients and distinguish them from FM patients. These data may support the contention that FM and CFS are separate disorders.

Musculoskeletal syndromes associated with malignancy (excluding hypertrophic osteoarthropathy).

PURPOSE OF REVIEW: To examine recent data about the association between rheumatic disorders and cancer. This article focuses on paraneoplastic rheumatic disorders, which usually precede by a short period of time the diagnosis of malignancy, and on malignant transformation, which occurs late in the course of rheumatic disorders. Evidence of causality between malignancies and rheumatic disorders was reviewed based on statistical indicators (standardized incidence ratios and odds ratios) and by applying Bradford Hill's criteria of causality. RECENT FINDINGS: Firm epidemiological evidence was found attesting that dermatomyositis and polymyostis may present as paraneoplastic syndromes. Several other musculoskeletal disorders may be present akin to paraneoplastic syndrome, based on clinicians' impressions, but with scarce epidemiological evidence supporting a causal determinism. In contrast, robust evidence has accumulated on the role of longstanding rheumatoid arthritis, Sjögren's syndrome and systemic sclerosis as premalignant conditions. Evidence that systemic lupus erythematosus may evolve into lymphoma is equivocal. SUMMARY: The link between malignancies and rheumatic disorders may impact on clinical practice. First, paraneoplastic rheumatic syndromes can provide the clinician with hints for earlier diagnosis of occult cancer. Second, the risk of malignant transformation during the course of rheumatic disorders may motivate the search for strategies aimed at prevention.

Orthostatic hypotension: framework of the syndrome.

According to the 1996 consensus definition, orthostatic hypotension (OH) is diagnosed when a fall in systolic blood pressure of at least 20 mm Hg and/or diastolic blood pressure of at least 10 mm Hg within 3 min of standing is recorded. The elements of orthostatic blood pressure drop that are relevant to the definition of OH include magnitude of the drop, time to reach the blood pressure difference defined as OH, and reproducibility of the orthostatic blood pressure drop. In each of these elements, there exist issues that argue for modification of the presently accepted criteria of OH. Additional questions need to be addressed. Should one standard orthostatic test be applied to different patient populations or should tests be tailored to the patients' clinical circumstances? Are different OH thresholds relevant to various clinical settings, aetiologies of OH and comorbidity? Which test has the best predictive power of morbidity and mortality?

Isolated periaortitis: clinical and imaging characteristics.

Chronic periaortitis includes a variety of conditions that have similar clinical and histopathological findings, and thus probably represents different manifestations of the same disease: idiopathic retroperitoneal fibrosis, perianeurysmal retroperitoneal fibrosis, and inflammatory abdominal aortic aneurysms. We describe the clinical and imaging characteristics of the nonaneurysmal form of chronic periaortitis, recognized as isolated periaortitis, in an adult male patient presented with low back pain.

Patterns of hypocapnia on tilt in patients with fibromyalgia, chronic fatigue syndrome, nonspecific dizziness, and neurally mediated syncope.

OBJECTIVES: To assess whether head-up tilt-induced hyperventilation is seen more often in patients with chronic fatigue syndrome (CFS), fibromyalgia, dizziness, or neurally mediated syncope (NMS) as compared to healthy subjects or those with familial Mediterranean fever (FMF). PATIENTS AND METHODS: A total of 585 patients were assessed with a 10-minute supine, 30-minute head-up tilt test combined with capnography. Experimental groups included CFS (n = 90), non-CFS fatigue (n = 50), fibromyalgia (n = 70), nonspecific dizziness (n = 75), and NMS (n =160); control groups were FMF (n = 90) and healthy (n = 50). Hypocapnia, the objective measure of hyperventilation, was diagnosed when end-tidal pressure of CO2 (PETCO2) less than 30 mm Hg was recorded consecutively for 10 minutes or longer. When tilting was discontinued because of syncope, one PETCO2 measurement of 25 or less was accepted as hyperventilation. RESULTS: Hypocapnia was diagnosed on tilt test in 9% to 27% of patients with fibromyalgia, CFS, dizziness, and NMS versus 0% to 2% of control subjects. Three patterns of hypocapnia were recognized: supine hypocapnia (n = 14), sustained hypocapnia on tilt (n = 76), and mixed hypotensive-hypocapnic events (n = 80). Hypocapnia associated with postural tachycardia syndrome (POTS) occurred in 8 of 41 patients. CONCLUSIONS: Hyperventilation appears to be the major abnormal response to postural challenge in sustained hypocapnia but possibly merely an epiphenomenon in hypotensive-hypocapnic events. Our study does not support an essential role for hypocapnia in NMS or in postural symptoms associated with POTS. Because unrecognized hypocapnia is common in CFS, fibromyalgia, and nonspecific dizziness, capnography should be a part of the evaluation of patients with such conditions.

Predicting outcomes on head-up tilt based on orthostatic hypotension patterns.

OBJECTIVE: To assess the frequency of different orthostatic hypotension (OH) patterns in patients having supine hypertension with OH ('SHOH') versus patients with OH and normal supine blood pressure ('OH alone'); and to relate OH patterns with outcomes on head-up tilt. METHODS: Consecutive patients with nonspecific dizziness were studied with a 10-min supine, 30-min head-up tilt test. Supine hypertension was diagnosed when supine systolic blood pressure (SBP) was at least 140 mmHg and/or supine diastolic blood pressure was at least 90 mmHg. OH was defined as SBP reduction of at least 20 mmHg within 3 min of tilt. OH patterns were identified corresponding to SBP time-curves during the initial 5 min of tilt: progressive, sustained and transient patterns. RESULTS: Among 400 patients tested, 31 had 'SHOH' and 39 had 'OH alone'. Frequencies of OH patterns were similar in both groups. The progressive OH pattern predicted symptomatic hypotension, leading to early tilt termination in all 'SHOH' and 88% of 'OH alone' patients. In comparison, tilt was early terminated in 33-48% of patients with sustained OH, transient OH and without OH. Early tilt termination was unrelated to age, gender, magnitude of supine SBP, pulse pressure and nadir SBP within 5 min tilt. CONCLUSIONS: Five minutes of postural challenge permitted assessing OH patterns. Outcome on protracted tilt was related to OH patterns, the worse outcome being likened to progressive OH, both in patients with 'SHOH' and in patients with 'OH alone'. Future studies will show whether OH patterns may serve as guidance for blood pressure therapy in selected patients.

Cardiovascular reactivity in fibromyalgia: evidence for pathogenic heterogeneity.

OBJECTIVE: To evaluate disease-specific cardiovascular reactivity patterns in patients with fibromyalgia (FM) using a recently described method called fractal and recurrence analysis score (FRAS). METHODS: The study group included 30 women with FM, average age 46.7 years (SD 7.03). An age matched group of 30 women with other rheumatic disorders or having a dysautonomic background [chronic fatigue syndrome (CFS), non-CFS fatigue, neurally mediated syncope, and psoriatic arthritis (PsA)] served as controls. Subjects were evaluated with a head-up tilt test with beat-to-beat recording of the heart rate (HR) and pulse transit time. A 10-minute supine phase was followed by 600 cardiac cycles recorded on tilt. Data were processed by recurrence plot and fractal analysis. Variables acting as independent predictors of the cardiovascular reactivity were identified in FM patients versus controls. RESULTS: No statistically significant differences were found between the groups by univariate analysis comparing 92 variables of cardiovascular reactivity in FM patients compared to controls. CONCLUSION: Study of cardiovascular reactivity utilizing a head-up tilt test and processing the data using the FRAS method did not reveal a specific FM-associated abnormality. Our data confirm studies that utilized other methodologies and reached similar conclusions. Patients with FM represent a heterogenous group with respect to their pattern of cardiovascular reactivity.

Search for disease-specific cardiovascular reactivity patterns: developing the methodology.

Aberrations of CVR (cardiovascular reactivity), an expression of autonomic function, lack specificity for a particular disorder. Recently, a CVR pattern particular to chronic fatigue syndrome has been observed. In the present study, we aimed to develop methodologies for assessing disease-specific CVR patterns. As a prototype, a population of 50 consecutive patients with FMF (familial Mediterranean fever) was studied and compared with control populations. A 10 min supine/30 min head-up tilt test with recording of the heart rate and blood pressure or the pulse transit time was performed. Five studies were conducted applying different methods. In each study, statistical analysis identified independent predictors of CVR in FMF. Based on regression coefficients of these predictors, a linear DS (discriminant score) was computed for every subject. Each study established an equation to assess CVR, calculate DS for FMF and determine the sensitivity and specificity of the DS cut-off. In each of the five studies, abnormal CVR was observed in FMF patients. The best accuracy (88% sensitivity and 90.1% specificity for FMF) was obtained by a method based on beat-to-beat heart rate and pulse transit time recordings. Data was processed by fractal and recurrence quantitative analysis with recordings in FMF patients compared with a mixed control population. Identification of disease-specific CVR patterns was possible with the methodologies described in the present study. In FMF, disease-specific CVR may be explained by the interplay between neuroendocrine loops specific to FMF with cardiovascular homoeostatic mechanisms. Recognition of disease-specific CVR patterns may advance the understanding of homoeostatic mechanisms and have implications in clinical practice.
