Cardiovascular disease is a leading cause of mortality among TTP survivors in clinical remission.

ABSTRACT: Immune-mediated thrombotic thrombocytopenic purpura (iTTP) survivors experience high rates of adverse health sequelae and increased mortality over long-term follow-up. We conducted this multicenter cohort study to evaluate long-term mortality and causes of death in iTTP survivors. Between 2003 and 2020, 222 patients were enrolled in the Ohio State University and Johns Hopkins TTP registries and followed for a median of 4.5 (interquartile range [IQR], 75 0.4-11.5) years. Nine patients died during their first iTTP episode, and 29 patients died during follow-up. Mortality rate was 1.8 times higher than expected from an age-, sex-, and race-adjusted reference population. Cardiovascular disease was a leading primary cause of death (27.6%) tied with relapsed iTTP (27.6%), followed by malignancy (20.7%), infection (13.8%), and other causes (10.3%). Male sex (hazard ratio [HR], 3.74; 95% confidence interval [CI], 1.65-8.48), increasing age (HR, 1.04; 95% CI, 1.01-1.07), and number of iTTP episodes (HR, 1.10; 95% CI, 1.01-1.20) were associated with mortality in a model adjusted for African American race (HR, 0.70; 95% CI, 0.30-1.65), hypertension (HR, 0.47; 95% CI, 0.20-1.08), chronic kidney disease (HR 1.46; 95% CI, 0.65-3.30), and site (HR, 1.46; 95% CI, 0.64-3.30). There was a trend toward shorter survival in patients with lower ADAMTS13 activity during remission (P = .078). Our study highlights the need for survivorship care and investigation focused on cardiovascular disease and early mortality in TTP survivors.

Project description:PurposeConduct a systematic umbrella review to evaluate the relationship of physical activity (PA) with all-cause mortality, cardiovascular mortality, and incident cardiovascular disease (CVD); to evaluate the shape of the dose-response relationships; and to evaluate these relationships relative to the 2008 Physical Activity Guidelines Advisory Committee Report.MethodsPrimary search encompassing 2006 to March, 2018 for existing systematic reviews, meta-analyses, and pooled analyses reporting on these relationships. Graded the strength of evidence using a matrix developed for the Physical Activity Guidelines Advisory Committee.ResultsThe association of self-reported moderate-to-vigorous physical activity (MVPA) on all-cause mortality, CVD mortality, and atherosclerotic CVD-including incident coronary heart disease, ischemic stroke and heart failure-are very similar. Increasing MVPA to guidelines amounts in the inactive US population has the potential to have an important and substantial positive impact on these outcomes in the adult population. The following points are clear: the associations of PA with beneficial health outcomes begin when adopting very modest (one-third of guidelines) amounts; any MVPA is better than none; meeting the 2008 PA guidelines reduces mortality and CVD risk to about 75% of the maximal benefit obtained by physical activity alone; PA amounts beyond guidelines recommendations amount reduces risk even more, but greater amounts of PA are required to obtain smaller health benefits; and there is no evidence of excess risk over the maximal effect observed at about three to five times the amounts associated with current guidelines. When PA is quantified in terms of energy expenditure (MET·h·wk), these relationships hold for walking, running, and biking.ConclusionsTo avoid the risks associated with premature mortality and the development of ischemic heart disease, ischemic stroke, and all-cause heart failure, all adults should strive to reach the 2008 Physical Activity Guidelines for Americans.

Project description:ObjectivesIndividuals with prior cancer diagnosis are more likely to have low muscle mass (LMM) than their cancer-free counterparts. Understanding the effects of LMM on the prognosis of cancer survivors can be clinically important. The aim of this study was to investigate whether risks for all-cause and cardiovascular disease (CVD)-specific mortality differ by status of LMM in cancer survivors and a matched cohort without cancer history.MethodsWe used cohort data from the 1999-2006 and 2011-2014 National Health and Nutrition Examination Survey. Participants included 946 adults surviving for ≥1 since cancer diagnosis and a matched cohort (by age, sex, and race) without cancer history (N = 1857). LMM was defined by appendicular lean mass and body height (men <7.26 kg/m2, women <5.45 kg/m2). Death was ascertained via the National Death Index and cause of death was assessed via International Classification of Diseases, Tenth Revision. Multivariable Cox proportional hazards models were used to estimate adjusted hazard ratio (aHR) and 95% confidence interval (CI) of LMM.ResultsThe mean age of cancer survivors and matched cohort was 60.6 y (SD 15) and 60.2 y (SD 14.9), respectively. The median follow-up was 10.5 y for survivors and 10.9 y for matched cohort. Overall, 22.2% of cancer survivors and 19.7% of the matched cohort had LMM, respectively. In all, 321 survivors (33.9%) and 495 participants (26.7%) in the matched cohort died during follow-up. CVD-specific deaths were identified in 58 survivors (6.1%) and 122 participants in the matched cohort (6.6%). The multivariable Cox model suggested that LMM was positively associated with all-cause (aHR, 1.73; 95% CI, 1.31-2.29) and CVD-specific (aHR, 2.13; 95% CI, 1.14-4.00) mortality in cancer survivors. The associations between LMM and risk for all-cause (aHR, 1.24; 95% CI, 0.98-1.56) and CVD-specific (aHR, 1.21; 95% CI, 0.75-1.93) mortality were not statistically significant in the matched cohort.ConclusionCancer survivors with LMM have an increased risk for all-cause and CVD-specific mortality. This increase appears to be larger than that in counterparts without cancer history.

Project description:ImportanceHispanics are the largest minority group in the United States and face a disproportionate burden of risk factors for cardiovascular disease (CVD) and low socioeconomic position. However, Hispanics paradoxically experience lower all-cause mortality rates compared with their non-Hispanic white (NHW) counterparts. This phenomenon has been largely observed in Mexicans, and whether this holds true for other Hispanic subgroups or whether these favorable trends persist over time remains unknown.ObjectiveTo disaggregate a decade of national CVD mortality data for the 3 largest US Hispanic subgroups.Design, setting, and participantsDeaths from CVD for the 3 largest US Hispanic subgroups-Mexicans, Puerto Ricans, and Cubans-compared with NHWs were extracted from the US National Center for Health Statistics mortality records using the underlying cause of death based on coding from the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (I00-II69). Mortality data were evaluated from January 1, 2003, to December 31, 2012. Population estimates were calculated using linear interpolation from the 2000 and 2010 US Census reports. Data were analyzed from November 2015 to July 2016.Main outcomes and measuresMortality due to CVD.ResultsParticipants included 688 074 Mexican, 163 335 Puerto Rican, 130 397 Cuban, and 19 357 160 NHW individuals (49.0% men and 51.0% women; mean [SD] age, 75 [15] years). At the time of CVD death, Mexicans (age, 67 [18] years) and Puerto Ricans (age, 68 [17] years) were younger compared with NHWs (age, 76 [15] years). Mortality rates due to CVD decreased from a mean of 414.2 per 100 000 in 2003 to 303.3 per 100 000 in 2012. Estimated decreases in mortality rate for CVD from 2003 to 2012 ranged from 85 per 100 000 for all Hispanic women to 144 per 100 000 for Cuban men, but rate differences between groups vary substantially, with Puerto Ricans exhibiting similar mortality patterns to NHWs, and Mexicans experiencing lower mortality. Puerto Ricans experienced higher mortality rates for ischemic and hypertensive heart disease compared with other subgroups, whereas Mexicans experienced higher rates of cerebrovascular disease deaths.Conclusions and relevanceSignificant differences in CVD mortality rates and changes over time were found among the 3 largest Hispanic subgroups in the United States. Findings suggest that the current aggregate classification of Hispanics masks heterogeneity in CVD mortality reporting, leading to an incomplete understanding of health risks and outcomes in this population.

Project description:ImportanceThe role of bullous pemphigoid (BP) in cardiovascular disease (CVD) mortality remains controversial, and analyses of causes of death among patients with BP based on individual data remain lacking.ObjectiveTo evaluate the risk of all-cause mortality, CVD mortality, and cancer mortality in patients with BP.Design, setting, and participantsThis cohort study identified patients who received a diagnosis of and treatment for BP during their dermatology clinic visits at a tertiary medical center in central Taiwan between January 1, 2007, and December 31, 2017. Controls were patients without BP and were individually matched to cases (4:1) according to age, sex, and date of the dermatology clinic visit. Data were analyzed from March 6, 2019, to April 2, 2021.ExposuresBullous pemphigoid was confirmed pathologically with typical direct immunofluorescence findings or clinically with typical clinical presentation, positive findings of an anti-basement membrane zone antibody test, and corticosteroid use for at least 28 cumulative days.Main outcomes and measuresMortality outcomes confirmed by the National Death Registry.ResultsOf 252 patients with BP and 1008 matched control patients (N = 1260), 685 (54.4%) were men and the median age was 78.0 (IQR, 70.3-84.8) years. Patients with BP had higher CVD mortality at 1 year (20 [7.9%] vs 13 [1.3%]), 3 years (28 [11.1%] vs 24 [2.4%]), and 5 years (31 [12.3%] vs 39 [3.9%]) compared with matched control patients. After adjusting for potential confounding variables, patients with BP had a 5-fold higher risk of CVD mortality at 1 year (hazard ratio [HR], 5.29 [95% CI, 2.40-11.68]), 3 years (HR, 5.79 [95% CI, 3.11-10.78]), and 5 years (HR, 4.95 [95% CI, 2.88-8.51]). Subgroup analyses revealed that the CVD mortality risk associated with BP was higher in patients without a history of hypertension (HR, 7.28 [95% CI, 3.87-13.69]) or CVD (HR, 6.59 [95% CI, 3.40-12.79]) and in patients without prior diuretic use (HR, 5.75 [95% CI, 3.15-10.50]) compared with matched control patients. In addition, all-cause mortality associated with BP was higher in patients without prior corticosteroid use than in control patients (HR 5.65 [95% CI, 4.19-7.61]).Conclusions and relevanceThe findings of this cohort study suggest that BP was associated with a 5-fold higher risk of CVD mortality, particularly in patients without underlying hypertension or CVD or those without prior corticosteroid or diuretic use. Future studies should investigate the benefits of routine monitoring and timely management of CVD symptoms and signs in patients with BP.
