Abstract
Introduction and Aim: Hypertension and proteinuria is known to cause renal and cardiovascular disease and mortality in patients irrespective of diabetes. It is beneficial to identify proteinuria and probable glomerular injury early to take preventive measures from cardiovascular event. In our study, we aimed to evaluate whether a biomarker such as nephrin can detect early glomerular injury in treatment naïve hypertensive subjects.
Materials and Methods: Forty newly diagnosed, treatment naïve hypertensive subjects were recruited for the study along with 40 normotensive controls after obtaining informed consent and procuring approval from. Institutional Ethics Committee. The hypertensive group was classified as diabetic and non-diabetic hypertensives and compared with apparently healthy controls (normotensive). Urine sample was analyzed for microalbumin, creatinine and nephrin. Blood sample was analyzed for glycated hemoglobin, urea, creatinine, sodium, and potassium. Statistical analysis was performed using ANOVA to compare the groups for various parameters. Odds ratio was calculated.
Results: Hypertensives were sub-grouped based on amount of microalbumin excreted. Urine nephrin excretion was significantly higher in hypertensive subjects than normotensive subjects (nephrin cut-off: 0.09 mg/g of creatinine). Urine nephrin (mg/g) was found to be elevated (median 0.15; interquartile range, 0.12 and 0.17) in hypertensives with normoalbuminuria and it was significantly higher than normotensive subjects (median 0.07; interquartile range, 0.04 and 0.09).
Conclusion: Urine nephrin may be used as a biomarker of early glomerular injury in hypertensive subjects even before microalbuminuria is detected.

J Pers Med 2022; 12:jpm12060971. [PMID: 35743755 PMCID: PMC9225554 DOI: 10.3390/jpm12060971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 06/09/2022] [Accepted: 06/13/2022] [Indexed: 11/19/2022] Open
Abstract
Proteinuria, frequently observed in hypertensive crisis, is a risk factor for cardiovascular and all-cause mortality in patients with hypertension. Here we investigated the association between proteinuria and all-cause mortality in patients with a hypertensive crisis in the emergency department (ED). This retrospective study included patients admitted to the ED of a tertiary referral center between 2016 and 2019 with hypertensive crisis (systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg); 3599 patients with an assay for proteinuria were included in this study. Proteinuria was defined as a trace or more protein on a urine dipstick test. Proteinuria was present in 1964 (54.6%) of 3599 patients. At 3 years, crude all-cause mortality rates were 10.8% for patients with negative proteinuria, 21.7% for those with trace proteinuria, 29.0% for those with proteinuria (1+), 32.0% for those with proteinuria (2+), and 35.4% for those with proteinuria (≥3+). After adjusting for age, sex, blood pressure, and comorbid conditions, the hazard ratio (95% confidence interval) for dipstick proteinuria was 1.91 (1.53–2.37) for those with trace proteinuria, 2.32 (1.85–2.91) for those with proteinuria (1+), 2.40 (1.86–3.10) for those with proteinuria (2+), and 2.40 (1.78–3.24) for those with proteinuria (≥3+) compared to the reference of negative proteinuria. In patients with hypertensive crisis, dipstick proteinuria was a significant predictor of all-cause mortality, and the risk of all-cause mortality increased in a dose-dependent manner according to its degree. Moreover, even trace proteinuria was associated with an increased risk of mortality. The dipstick urine test could be used as a simple and useful method for risk assessment of all-cause mortality in patients with hypertensive crisis.

Abstract
Background Cardiovascular diseases are a group of disorders of the heart and blood vessels. Globally an estimated 17.9 million people died from cardiovascular diseases, which covers 31% of all global deaths, and the three quarters taking place in developing countries. Hypertension is the major cause of cardiovascular diseases. Its influence is high with other risk factors. This study aimed to determine the major risk factors of cardiovascular disease among hypertensive patients at Jimma University Medical Center. Methods Using December to January 2017 hypertension-related report of Jimma University Medical Center (JUMC), a retrospective cohort study type was conducted on purposively selected 343 patients. Three nurses from JUMC participated in the data collection, and the data were fitted using the Cox-Proportional Hazard (Cox-PH) model. Results About 138 (40.23%) patients were experienced cardiovascular disease at 28 months median time. From the Cox-PH model, the hazard ratio and 95% CI of age (HR = 1.0495, 95% CI: 1.0250-1.0747), urban (HR = 2.1225, 95% CI: 1.3813-3.2613), diabetes mellitus (HR = 1.702, 95% CI: 1.0082-2.8731), proteinuria (HR = 1.8749, 95% CI: 1.2675-2.7734), two drug users (HR = 0.2533, 95% CI: 0.1376-0.4662), systolic blood pressure (HR = 1.0343, 95% CI: 1.0147-1.0542) and pulse rate (HR = 1.0111, 95% CI: 0.9933-1.0293). Conclusion The presence of proteinuria, diabetes mellitus, and being an urban resident had a great impact on the cardiovascular diseases of hypertensive patients.

Abstract
OBJECTIVES The objective of this study was to determine if inflammatory markers are associated with antithrombin activity in cats. METHODS For a retrospective population of 231 cats admitted to a referral hospital, antithrombin activity was classified as decreased (n = 77), intermediate (n = 97) or in the upper quartile (n = 57). Odds ratios (ORs) were calculated for an association between decreased or upper quartile activity and hypoalbuminemia, hyperfibrinogenemia, band neutrophilia and toxic change. Multiple logistic regression was performed to determine if an association between band neutrophilia and decreased antithrombin activity was independent of decreased hepatic synthesis, consumptive coagulopathy or protein loss. RESULTS Cats with decreased antithrombin activity were more likely than cats with intermediate-to-upper quartile activity to have band neutrophilia (OR 2.85, P = 0.0050), hypoalbuminemia (OR 12.1, P <0.0001) or toxic neutrophils (OR 4.47, P <0.0001). Cats with antithrombin activity in the upper quartile were less likely than those with intermediate-to-low activity to have hypoalbuminemia (OR 0.31, P = 0.0023) or toxic neutrophils (OR 0.44, P = 0.033). In a regression model that included other mechanisms for decreased antithrombin, band neutrophilia remained associated with decreased antithrombin activity (adjusted OR 2.62, P = 0.013). CONCLUSIONS AND RELEVANCE Contrary to previous studies suggesting antithrombin is a feline positive acute phase protein, this study demonstrates an association between decreased antithrombin activity and inflammation. Further studies are needed to determine the mechanistic basis of this association.

Abstract
Introduction By definition, hypertensive cardiopathy is a series of complex and variable effects responsible for the chronic elevation of blood pressure in the heart. It stands out within a broad spectrum of cardiovascular diseases associated with hypertension. Objective To evaluate the capacity to predict the development of adaptive changes to hypertensive cardiopathy within ten years following diagnosis of the condition, using a model based on prognostic factors. Methods A prospective cohort study was conducted in hypertensive patients. The patients were followed at the specialized hypertension physicians office of the specialty policlinic attached to Carlos Manuel de Céspedes University Hospital, in the Bayamo Municipality, Granma Province, Cuba, from 1 January 2008 to 31 December 2018. Results Coxs proportional regression model showed a significant statistical relationship between most of the factors and the development of the adaptive changes in hypertensive cardiopathy within ten years of follow-up after the diagnosis of this condition. The lack of blood pressure control (Hazard ratio: 2.090; confidence interval 95%: 1.688 to 2.588; p: 0.000) followed by stage 2 of hypertension (hazard ratio: 1.987; confidence interval 95%: 1.584 to 2.491; p: 0.000) were the main factors. Internal validation of the model, discriminant capacity (C- statistic: 0.897) and calibration Hosmer-Lemeshow (χ2: 5.384; p: 0.716), was acceptable. Conclusions We develop a model to predict the progression of hypertensive cardiopathy from grade I to grade IV with adequate discriminatory capacity. The model is based on prognostic factors, among which characteristic effects of arterial hypertension, diabetes mellitus, and chronic kidney disease stood out.

Abstract
INTRODUCTION Among the conditions resulting from target organ damage by arterial hypertension, hypertensive cardiopathy is the one that exhibits the highest morbidity and mortality rates. Its prevention should be a target of all high blood pressure medical care programs. OBJECTIVE To identify risk factors for the development of hypertensive cardiopathy. METHODS A prospective cohort study was carried out in hypertensive patients assisted at the specialized arterial hypertension physicians offices of the Carlos Manuel de Céspedes Specialty Policlinic attached to the General University Hospital, Bayamo Municipality, Granma Province, Cuba, from January 1st, 2000 to December 31st, 2009. RESULTS Multivariate analysis done to estimate the hazard rate (HR) of developing hypertensive cardiopathy, showed significant independent statistic association for most factors. The first place was occupied by lack of blood pressure control (HR=2.022; 95% CI: 1.659-2.465; p<0.005), followed by hypertension stage 2 (HR=2.015; 95% CI: 1.715-2.366; p<0.005). Another factors with significant HRs were microalbuminuria (HR=1.9; 95% CI: 1.6-2.2) and age over 60 years (HR=1.6; 95% CI: 1.4-1.9). CONCLUSIONS Several risk factors must be considered for the prevention of hypertensive heart disease in high blood pressure patients.

Association of home and ambulatory blood pressure changes with changes in cardiovascular biomarkers during antihypertensive treatment. Am J Hypertens 2012; 25:306-12.

Abstract
BACKGROUND Our aim was to assess whether home blood pressure (HBP) and ambulatory BP monitoring measurement (ABPM), in addition to office BP (OBP) predict changes of cardiovascular biomarkers during antihypertensive treatment. METHODS Two hundred and fifty-two hypertensive patients (mean age, 68 years; men: 41%) underwent measurements of OBP, HBP, ABPM, and cardiovascular biomarkers (urinary albumin excretion (UAE) and brain natriuretic peptide (BNP)) before and after 6 months of treatment with candesartan (± thiazide-diuretics). RESULTS During the intervention, the OBP, HBP, daytime and night-time BP, and UAE levels were all significantly reduced (all P < 0.01). BNP was reduced only in the patients using diuretics (P = 0.003). For predicting the treatment-induced change in UAE, each of home systolic BP (SBP) and night-time SBP changes, but not daytime SBP change, had independent and significant value beyond OBP measurement (both P < 0.05). In contrast, for predicting the treatment-induced change in BNP, night-time SBP changes, but not home or daytime SBP changes, had significant value beyond OBP measurement (both P < 0.05). Patients who achieved a reduction in all three SBP parameters (office, home, and night-time SBP; n = 122) showed a more significant reduction of UAE compared with those who did not (-52.6 vs. -32.5%; P = 0.001), and patients who achieved a reduction in both office and night-time SBP (n = 134) showed a more significant reductions of BNP than those who did not (-12.9 vs. +12.8%; P < 0.05). CONCLUSIONS HBP and ABPM measurements, particularly night-time SBP values provide additional information for predicting treatment-induced changes of cardiovascular biomarkers when used in conjunction with office SBP measurement during antihypertensive treatment.
