Several kidney diseases associated with complement activation. Complement activation occurs in progressive chronic kidney disease and may contribute to the chronic inflammation that is characteristically found in the kidney. This study was aimed to detect the level of complement system in kidney failure patients. This study was included (30) patients with renal failure and (15) healthy donors as control group. Serum samples separated from the whole blood of patients and healthy individuals. C3, C4, and high sensitive C- reactive protein (hsCRP) levels were estimated for all samples. The results were analyzed according to patients who were dialysis, non-dialysis, with diabetes, without diabetes, with high blood pressure, and without high blood pressure. The results showed that there was a significant increase (P < 0.05) in C3 level for patients with renal failure (154.12 mg/dl) compared to control group (126.08 mg/dl) while C4 level for renal failure patients (35.38 mg/dl) showed no significant change compared to control group (36.26 mg/dl). However, C3 level of patients under dialysis (152.15 mg/dl), not dialysis (162.01 mg/dl), with diabetic (155.80 mg/dl), and without diabetic (153 mg/dl) recorded significant elevation compared with control group (126.08 mg/dl) but C4 level did not show any significant change for all groups. C3 and C4 concentrations did not record significant alteration (P < 0.05) in patient with hypertension, nonhypertension, and control group. Moreover, seropositivity of CRP for patients with renal failure was ranged from 33.33% to 60% in all patients groups included in this study. hsCRP concentration significantly elevated (P < 0.05) in under dialysis (1.787 mg/L), nondialysis (1.583 mg/L), with diabetic (2.766 mg/L), nondiabetic (1.066 mg/L), with hypertension (1.84 mg/L), and nonhypertension (1.26 mg/L) when compared with control group (0.667 mg/L). The present findings suggest that the increased serum levels of C3, C4, and hs-CRP reflect the of kidney injury. Hence, this reflects the complement system as an important mediator of kidney injury and the role of anti-complement therapy in nephropathy will expand in the future.

Blood pressure is the force of blood pushing against blood vessel walls as the heart pumps out blood, and high blood pressure, also called hypertension, is an increase in the amount of force that blood places on blood vessels as it moves through the body. Factors that can increase this force include higher blood volume due to extra fluid in the blood and blood vessels that are narrow, stiff, or clogged(1). High blood pressure can damage blood vessels in the kidneys, reducing their ability to work properly. When the force of blood flow is high, blood vessels stretch so blood flows more easily. Eventually, this stretching scars and weakens blood vessels throughout the body, including those in the kidneys.

Introduction: Cardiovascular diseases (CVD) are known as important reasons of the increased morbidity and mortality observed in patients with chronic renal failure (CRF). The association of serum Interlukin-6 , homocysteine as well as other cardiovascular risk factors in relation to existence and cause of CVD were investigated. Method: In this study 200 CRF patients were recruited and further stratified into group with Male and Female as case groups. Those without renal failure were assigned as control group (n=200). Results: The patients with CRF showed a significant increase in plasma levels of Cpk-MB homocysteine and C-reactive protein (CRP) compared to control. The positive association were observed between homocysteine, Urea and Hs-CRP, IL_6 . It shows a significant Association of parameters in CRF . Conclusion: The results demonstrated elevation in plasma values IL-6 , homocysteine and HS-CRP in patients with CRF . However, these modifications may be lead to atherosclerosis and consequence CVD event. These parameters may be important with respect to the high morbidity and mortality of CVD found in patients with CRF.

Essential hypertension is high blood pressure that doesn't have any known etiopathology. Most of sufferers (85%) are asymptomatic and as per available reports, in more than 95% cases of hypertension under lying cause is not found. It is estimated that 600 million people are affected worldwide. Hypertension is a major risk factor for the development of cardiovascular diseases (CVD). Its impact is greatest on stroke, MI and end stage is renal failure as it’s known as a Silent Killer. Hence there is no direct reference of hypertension in Ayurvedic classics by name as well as by its path physiological views. Many works have been carried out on hypertension to evaluate the perfect diagnosis and mode of treatment on the basis of Different nomenclatures also have been adopted by Ayurveda experts like Raktagata Vata, Raktagata Vyana Vaisamya, Uccha Rakta Chapa, Raktavrita Vata, Siragata Vata etc. Keywords: Essential hypertension, Raktagata Vyana Vaisamya, Uccha Rakta Chapa, Cardiovascular diseases, Silent Killer.

Background. The individual and typological features of the central nervous system are interpreted as highly genetically determined. Each somatotype is characterized by morphofunctional features of the activity of different systems, including the circulatory system. Objective. The aim of the research was to study the features of the main individual and typological parameters of higher nervous activity in persons of different somatotype with normal and high blood pressure (BP). Methods. In the control group of the surveyed patients the BP value corresponded to the optimal level according to the WHO classification (125 people). The second group consisted of individuals, whose systolic blood pressure exceeded 130 mmHg at the time of the study and (or) diastolic – 85 mmHg (135 people). Somatotyping technique by Carter and Heath was used. Functional mobility (FMNP) and strength of nervous processes (SNP) were determined using the Diagnost-1 program (Makarenko and Lizogub). Results. In the individuals with predominance of ecto- and mesomorphic somatotype component, higher levels of major nervous processes were reported in response to strenuous processing of information, which was associated with more advanced mechanisms of information processing, its neurophysiological support. In people with endomorphic somatotype the lower levels of FMNP and SNP were clearly detected that could indicate that the speed characteristics of the nervous processes in them are at a lower level. Conclusions. In normal blood pressure, the highest indicator of FMNP was found in the individuals with predominance of ecto- and mesomorphic component. In the group with high blood pressure, the indicator at the level below the average was in endomorphs. Predominance of the ectomorphic component tended to increase in the surveyed, and in the mesomorphs was at the average level. The lowest level of SNP was found in the individuals with endomorphic somatotype of both groups.

INTRODUCTION The causes of high blood pressure are complex and based on an interaction between multiple biological factors and behaviours. Insulin resistance and inflammation are commonly acknowledged mechanisms in the development of CVD, while insulin resistance and relative body weight correspondingly predict the development of high blood pressure. HYPOTHESIS We aimed to compare insulin resistance, relative body weight, and inflammation in the association with SBP. METHODS In 2001-2005 a random sample of residents aged 30-74 years in the municipalities of Vara and Skövde, South-western Sweden, were invited to a survey of cardiovascular risk factors. In all 1811 participants in Vara (participation rate 81%) and 1005 participants in Skövde (70%) were enrolled. Subjects with a known history of hypertension were excluded for the current study. Specially trained nurses saw all subjects in the morning after a 10 hours over night fast, and venous blood samples were taken. A physical examination included body height and body weight (light cloths and no shoes), blood pressure was measured twice in a supine position after a 5 minutes rest (arm in heart level). The mean of the 2 measurements was used for statistical analyses. Hs-CRP and plasma insulin were analysed, and BMI and HOMA-index were calculated using standard algorithms. The log form of HOMA-ir was used in statistical analyses. Associations were explored in males and females separately using multivariate linear regression. RESULTS In all 2538 subjects, 1266 men (50%) and 1272 women (50%) without known hypertension were included. BMI and HOMA-ir were both significantly associated with SBP in both males and females, while hs-CRP was associated with SBP in women only. These factors were accordingly entered into a multivariate linear regression model also including age. In men HOMA-ir [regression coefficient, (95% confidence interval), and p-value] [5.4 (2.5-8.4), p<0.001], was significantly associated with SBP, while BMI [0.2 (-0.3-0.5), p=0.087], and CRP was not [0.02 (-0.1-0.1), p=0.138]. In women all three mechanisms came out significantly; HOMA-ir [5.4 (2.2-8.6), p<0.001], BMI [0.4 (0.2-0.5), p<0.001], and CRP [0.2 (0.02-0.4), p=0.031]. There were statistically significant interaction terms between gender and CRP (p=0.037), and gender and HOMA-ir (P=0.045), respectively, while no corresponding interaction was found for BMI. CONCLUSIONS Our study confirms a strong impact of insulin resistance and relative body weight on blood pressure levels in both men and women. However, a significant association between hs-CRP and systolic blood pressure in women was not seen in men. Gender differences in insulin resistance and inflammation were statistically confirmed by interaction terms. These findings have implications for future research and for development of clinical practice.

A 77-year-old woman on metoprolol and lisinopril presented to an emergency department with giddiness after vomiting for few hours. She was found to have low blood pressure and bradycardia 38 beats per minute due to atrioventricular nodal blockade. Her bradycardia was refractory to atropine and dopamine infusion; but improved with calcium gluconate. She was found to have acute kidney injury and hyperkalemia at 6.4 mEq/L. This is a case of Bradycardia, Renal Failure, Atrioventricular-Nodal Blockers, Shock, and Hyperkalemia (BRASH) syndrome, precipitated by dehydration and perpetuated by atrioventricular blockade, illustrating the degree of bradycardia and electrocardiographic changes being out of proportion to the potassium level. BRASH syndrome should be recognized and intervened early in the course to avoid the patient entering a vicious cycle that could be rapidly fatal.

Abstract Introduction Carfilzomib (Cfz), an irreversible proteasome inhibitor, is a first line antineoplastic agent indicated for relapsed/refractory multiple myeloma, with its clinical use being hampered by cardiovascular adverse effects. Hypertension, is the most common cardiovascular side effect of Cfz, remaining of unknown pathogenicity. Purpose Considering that management of Cfz-related hypertension remains an unmet clinical need and that renal function plays a pivotal role in blood pressure regulation we sought to investigate the renal contribution in Cfz-induced hypertension. Methods We have previously established a translational model of Cfz-induced cardiomyopathy, based on clinically applicable dose regimens and we have concluded that two and four dose protocols successfully resemble the clinical observations in vivo. Herein, sixty C57Bl/6 male mice (12–14 weeks old) were randomized to: 1. Two doses Protocol: i. Control (N/S 0.9%), ii. Cfz (8mg/kg) for two consecutive days; and 2. Four doses Protocol: i. Control (N/S 0.9%), ii. Cfz (8mg/kg) for seven days intraperitoneally. Systolic (SBP) and diastolic blood pressure (DBP) were measured by tail cuffs; the latter protocol was repeated and urine collection was performed via metabolic cages studies. Renal samples were collected for histological, proteomic, metabolomic and molecular signaling analyses. Finally, eplerenone, a mineralocorticoid receptor (MR) blocker, was orally co-administered with Cfz to the mice daily (165 mg/kg) in the four doses protocol. Results Cfz increased SBP only in the four doses protocol (78.50±2.05 vs 68.20±0.73 in the Control group, **P&lt;0.01). Histological evaluation of the kidneys revealed a juxtaglomerular apparatus hyperplasia (JAH) in the same dose regimen. Proteomic analysis presented that metabolic and transport of small molecules pathways were differentially regulated in the Cfz treated murine kidneys. Metabolomic analysis revealed an increase in urea cycle metabolites (L-Alanine, L-Glutamine, glutamate, aspartate) and taurine content in the kidneys. Additionally, mice presented decreased diuresis without any differences in other metabolic parameters. In parallel an upregulation of β-ENaC expression and activation of MR/SGK-1 signaling in the kidneys was observed, indicating that Cfz activates MR signaling. Co-administration of eplerenone and Cfz, restored diuresis, decreased SBP and inhibited MR/SGK-1 signaling in the kidneys. Conclusions Activation of MR signaling by Cfz in the kidneys orchestrates renal water/salt retention and drives an increase in blood pressure in vivo. Histological and metabolomic analyses present that Cfz induces an acute kidney injury and a tonicity increase. Eplerenone reversed Cfz-induced blood pressure increase and restored diuresis by inhibiting MR/SGK-1 signaling. Therefore, MR blockade emerges as a potent therapeutic approach against Cfz-related cardiovascular adverse events. FUNDunding Acknowledgement Type of funding sources: None.

Background: Hypertension and renal injury are common complications of type 2 diabetes mellitus (T2DM). Hyperglycemia stimulates renal proximal tubular angiotensinogen (AGT) expression via elevated oxidative stress contributing to the development of high blood pressure and diabetic nephropathy. The sodium glucose cotransporter 2 (SGLT2) in proximal tubules is responsible for the majority of glucose reabsorption by renal tubules. We tested the hypothesis that SGLT2 inhibition with canagliflozin (CANA) prevents intrarenal AGT augmentation and ameliorates kidney injury and hypertension in T2DM. Methods: We induced T2DM in New Zealand obese mice with a high fat diet (DM, 30% fat) with control mice receiving regular fat diet (ND, 4% fat). When DM mice exhibited > 350 mg/dL blood glucose levels, both DM- and ND-fed mice were treated with 10 mg/kg/day CANA or vehicle by oral gavage for 6 weeks. We evaluated intrarenal AGT, blood pressure, and the development of kidney injury. Results: Systolic blood pressure in DM mice (133.9 ± 2.0 mm Hg) was normalized by CANA (113.9 ± 4.0 mm Hg). CANA treatment ameliorated hyperglycemia-associated augmentation of renal AGT mRNA (148 ± 21 copies/ng RNA in DM, and 90 ± 16 copies/ng RNA in DM + CANA) and protein levels as well as elevation of urinary 8-isoprostane levels. Tubular fibrosis in DM mice (3.4 ± 0.9-fold, fibrotic score, ratio to ND) was suppressed by CANA (0.9 ± 0.3-fold). Furthermore, CANA attenuated DM associated increased macrophage infiltration and cell proliferation in kidneys of DM mice. Conclusions: CANA prevents intrarenal AGT upregulation and oxidative stress and which may mitigate high blood pressure, renal tubular fibrosis, and renal inflammation in T2DM.

AbstractTransplant-associated thrombotic microangiopathy (TA-TMA) is a severe and life-threatening complication of hematopoietic cell transplantation (HCT) that often coincides with graft-versus-host-disease (GVHD). Although endothelial damage seems to be the common denominator for both disorders, the role of complement system, neutrophils, and coagulation has not been clarified. In an effort to distinguish the pathogenesis of TA-TMA from GVHD, we evaluated markers of complement activation, neutrophil extracellular trap (NET) release, endothelial damage, and activation of coagulation cascade in the circulation of patients with these two disorders, as well as control HCT recipients without TA-TMA or GVHD. We observed that the terminal complement product C5b-9 levels, the levels of markers of NET formation, and thrombin–antithrombin complex levels were significantly increased in the TA-TMA group compared with patients without complications, whereas there was no significant difference between the GVHD and the control group. On the other hand, the levels of circulating thrombomodulin, an endothelial damage marker, were significantly increased in both TA-TMA and GVHD patients. These findings propose a role for the interplay between complement system, neutrophil activation through NET release, and activation of the coagulation cascade in TA-TMA.
