Abstract
PURPOSE Diabetes mellitus (DM) increases the risk of morbidity and mortality after liver resection. Albuminuria is associated with a higher risk for all-cause and cardiovascular mortality. This study evaluated albuminuria as a predictor of the outcome of living donor liver transplantation (LDLT) in patients with pre-existing DM. METHODS This retrospective study involved 103 type II diabetic patients with end-stage liver disease who received LDLT. Preoperative spot urine albumin: creatinine ratio was used to determine the degree of albuminuria. The primary outcome measure was the impact of urinary albumin excretion on the 3-year mortality rate after LDLT in this diabetic cohort. RESULTS Hepatitis C virus infection was the main cause of cirrhosis. Albuminuria was detected in 41 patients (39.8%); 15 had macroalbuminuria, while 26 had microalbuminuria. Patients with microalbuminuria were significantly older than those with macroalbuminuria and normal albumin in urine. After 3 years, twenty-four patients (23.3%) died within 3 years after LT. Myocardial infarction was the leading cause of death (25%). Albuminuria was an independent factor affecting 3-year mortality with an odds ratio of 5.17 (95% CI: 1.86-14.35). CONCLUSION Preoperative albuminuria is an independent factor affecting mortality within 3 years after LDLT in type II diabetic patients. Myocardial infarction was the leading cause of death in 25% of cases, followed by hepatocellular carcinoma recurrence, sepsis, and graft failure.KEY MESSAGESDiabetes mellitus (DM) increases the risk of morbidity and mortality after liver resection.Albuminuria is associated with a higher risk for all-cause and cardiovascular mortality.Preoperative albuminuria is a significant predictor of mortality within 3 years after LDLT in diabetic patients.

Early life body mass index trajectories and albuminuria in midlife: A 30-year prospective cohort study. EClinicalMedicine 2022; 48:101420. [PMID: 35516445 PMCID: PMC9065297 DOI: 10.1016/j.eclinm.2022.101420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 04/09/2022] [Accepted: 04/11/2022] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Albuminuria is a marker of vascular dysfunction and is associated with chronic renal and cardiovascular diseases. Data on the association between the longitudinal patterns of weight change early in life and albuminuria later in life are limited. We aimed to identify the body mass index (BMI) trajectory across a 30-year span and evaluate its association with middle-age albuminuria. METHODS Of the 4623 participants aged 6-18-year-old recruited by Hanzhong Adolescent Hypertension Study cohort in northern China from March 10, 1987 to June 3, 2017, a total of 1,825 participants followed up with 6 visits over 30 years were enrolled. Group-based trajectory modeling was used to identify distinct BMI trajectories in longitudinal analyses. Albuminuria was defined as a urinary albumin-to-creatinine ratio (uACR) ≥ 30 mg/g. FINDINGS Three distinct BMI trajectories were identified: low-increasing (n = 671, 36.8%), moderate-increasing (n = 940, 51.5%), and high-increasing (n = 214, 11.7%); male participants exhibited a steeper increase in BMI than females. The uACR was increased linearly from the low- to high-increasing group. A total of 201 individuals developed albuminuria, with an incidence of 11.0%. Compared with the low-increasing group, the odds ratio (OR) of albuminuria in middle age was 2.13(95% confidence interval [CI]: 1.26 to 3.61) for the high-increasing group after full adjustment for age, sex, smoking, alcohol consumption, marital status, systolic blood pressure, diabetes, and hyperlipidemia. The unadjusted ORs of the high-increasing BMI group were 5.08 (2.76-9.37) for males and 3.45 (1.78-6.69) for females, and the association remained significant in males in the fully adjusted models. INTERPRETATION Higher BMI trajectories are associated with higher uACR and an increased risk of albuminuria in middle age, especially in males. Identifying long-term BMI trajectories from an early age may assist in predicting the risk of renal diseases and cardiovascular disease later in life.

Abstract
AIMS Advanced glycation endproducts (AGEs) are sugar-modified adducts which arise during non-enzymatic glycoxidative stress. These compounds may become systemically elevated in disease states, and accumulate in tissue, especially on long-lived proteins. AGEs have been implicated in various acute, and chronic diseases, stressing the need for reliable and comprehensive measuring techniques. Measurement of AGEs in tissue such as skin requires invasive skin biopsies. The AGE Reader has been developed to assess skin autofluorescence (SAF) non-invasively using the fluorescent properties of several AGEs. RESULTS/CONCLUSION Various studies have shown that SAF is a useful marker of disease processes associated with oxidative stress. It is prospectively associated with the development of cardiovascular events in patients with diabetes, renal or cardiovascular disease, and it predicts diabetes, cardiovascular disease, and mortality in the general population. However, when measuring SAF in individual subjects, several factors may limit the reliability of the measurement. These include endogenous factors present in the skin that absorb emission light such as melanin in dark-skinned subjects, but also factors that lead to temporal changes in SAF such as acute diseases and strenuous physical exercise associated with glycoxidative stress. Also, exogenous factors could potentially influence SAF levels inadvertently such as nutrition, and for example the application of skin care products. This review will address the AGE Reader functionality and the endogenous, and exogenous factors which potentially influence the SAF assessment in individual subjects.

Abstract
The clinical significance of albuminuria in diabetic subjects and the impact of its reduction on the main cardiorenal outcomes by different drug classes are among the most interesting research focuses of recent years. Although nephrologists and cardiologists have been paying attention to the study of proteinuria for years, currently among diabetics, increased urine albumin excretion ascertains the highest cardio-renal risk. In fact, diabetes is a condition by itself associated with a high-risk of both micro/macrovascular complications. Moreover, proteinuria reduction in diabetic subjects by several treatments lowers both renal and cardiovascular disease progression. The 2019 joint ESC-EASD guidelines on diabetes, prediabetes and cardiovascular (CV) disease assign to proteinuria a crucial role in defining CV risk level in the diabetic patient. In fact, proteinuria by itself allows the diabetic patient to be staged at very high CV risk, thus affecting the choice of anti-hyperglycemic drug class. The purpose of this review is to present a clear update on the role of albuminuria as a cardio-renal risk marker, starting from pathophysiological mechanisms in support of this role. Besides this, we will show the prognostic value in observational studies, as well as randomized clinical trials (RCTs) demonstrating the potential improvement of cardio-renal outcomes in diabetic patients by reducing proteinuria.

Abstract
Objectives To assess the influence of abnormalities in fluid status and body composition on agreement between multifrequency bioimpedance analysis (MF-BIA), segmental BIA (ΣBIA), the Watson formula, and tracer dilution techniques. Design Cross-sectional. Setting Multicenter. Patients 40 patients (29 males, 11 females) on peritoneal dialysis (PD). Main Outcome Measures Agreement between the various techniques used to assess total body water (TBW) [MF-BIA, deuterium oxide (D2O), and the Watson formula] and extracellular water (ECW) [MF-BIA, bromide dilution (NaBr), and ΣBIA], also in relation to the relative magnitude of the body water compartments [ECW (NaBr):body weight (BW) and TBW (D2O):BW] and body composition (DEXA). Second, the relation between body water compartments with echocardiographic parameters. Results Wide limits of agreement were observed between tracer dilution techniques and MF-BIA [TBW (D2O – MF-BIA) 2.0 ± 3.9 L; ECW (NaBr – MF-BIA) –2.8 ± 3.9 L], which were related to the relative magnitude of the body water compartments: r = 0.70 for ECW and r = 0.40 for TBW. ΣBIA did not improve the agreement [ECW (NaBr – ΣBIA): 3.7 ± 2.9 L]. Also, wide limits of agreement were observed between D2O and the Watson formula (–2.3 ± 3.3 L). The difference between D2O and Watson was related to hydration state and to percentage of fat mass ( r = 0.70 and r = –0.53, p < 0.05). Both ECW and TBW as assessed by BIA and tracer dilution were related to echocardiographic parameters. Conclusion Wide limits of agreement were found between MF-BIA and ΣBIA with dilution methods in PD patients, which were related to hydration state itself. The disagreement between the Watson formula and dilution methods was related to both hydration state and body composition.

Abstract
We investigated the mechanism by which diabetes renders the capillary endothelium more permeable to macromolecules in the lungs of short-term diabetic rats. We used quantitative immunocytochemistry (ICC) to comparatively assess the permeability of alveolar capillaries to serum albumin in diabetic and normoglycemic animals. The effect of diabetes on the population of endothelial caveolae was evaluated by morphometry and by ICC and immunochemical quantification of the amount of caveolin in the whole cell or associated with the purified endothelial plasma membrane. A net increase in the amount of serum albumin taken up by the plasmalemmal vesicles of alveolar endothelial cells and transported to the interstitium was documented in diabetic animals. Interendothelial junctions were not permeated by albumin molecules. The alveolar endothelial cells of hyperglycemic rats contain more caveolae (1.3-fold), accounting for a larger (1.5-fold) fraction of the endothelial volume than those of normal animals. The hypertrophy of the caveolar compartment is accompanied by overexpression of endothelial caveolin 1. Although the aggregated thickness of the endothelial and alveolar epithelium basement membranes increases in diabetes (1.3-fold), the porosity of this structure appears to be unchanged. Capillary hyperpermeability to plasma macromolecules recorded in the early phase of diabetes is explained by an intensification of transendothelial vesicular transport and not by the destabilization of the interendothelial junctions.

Abstract
Background We aimed to estimate the glomerular filtration rate (GFR) in women with
polycystic ovary syndrome (PCOS) and to determine the relationship between GFR with
C-reactive protein (CRP) and uric acid. Materials and Methods In this cross-sectional study, one-hundred and forty PCOS
women and 60 healthy subjects were evaluated. The study was carried out at Endocrinol-
ogy Outpatient Clinic, Erzurum Training and Research Hospital, Erzurum, Turkey, from
December 2010 to January 2011. GFRs were estimated by Modification of Diet in Renal
Disease (MDRD) formula. CRP, urinary albumin excretion (UAE) and uric acid levels
were also measured. Results GFRs were significantly higher in PCOS group than control (135.24 ±
25.62 vs. 114.92 ± 24.07 ml/min per 1.73 m2). CRP levels were significantly higher
in PCOS patients (4.4 ± 3.4 vs. 2.12 ± 1.5 mg/l). The PCOS group had significantly
higher serum uric acid levels (4.36 ± 1.3 mg/dl vs. 3.2 ± 0.73 mg/dl). There was also
significantly higher proteinuria level in PCOS patients. Conclusion Even though PCOS patients had higher GFR, serum uric acid and UAE val-
ues than control patients, the renal function was within normal limits. Increased GFR in
PCOS women positively correlates with elevated serum CRP and uric acid.

Abstract
BACKGROUND Increased microvascular permeability is a hallmark of microangiopathy in Type I diabetes mellitus and is associated with endothelial dysfunction and haemodynamic alterations. Type II diabetes mellitus is characterized by insulin resistance and hyperinsulinaemia. The purpose of this study was to determine whether acute hyperinsulinaemia, under both normoglycaemic and hyperglycaemic conditions, increases skin capillary permeability through its effect on skin haemodynamics, capillary recruitment or circulating markers of endothelial dysfunction in Type II diabetes. METHODS Nine Type II diabetic patients without microalbuminuria, (pre-) proliferative retinopathy or clinical neuropathy underwent three glucose clamps of 210 min., in random order, on separate days. A "standard" clamp (insulin-infusion rate 30 mU kg(-1) h(-1), glucose-target 5.0 mmol/L) was compared with a hyperinsulinaemic (insulin-infusion rate 150 mU kg(-1) h(-1), glucose-target 5.0 mmol/L) and a hyperinsulinaemic, hyperglycaemic (insulin-infusion rate 150 mU kg(-1) h(-1), glucose-target 12.0 mmol/L) clamp. Skin capillary permeability and density were measured using large-window sodium fluorescein videodensitometry, and skin blood flow by laser Doppler flowmetry. Endothelial dysfunction was estimated from increases in soluble intercellular adhesion molecule-1 (sICAM-1) and von Willebrand factor antigen (vWF). RESULTS No differences were found in skin capillary permeability, skin haemodynamics and capillary density at the end of the three glucose clamp periods. sICAM-1 and vWF did not increase as compared to the standard glucose clamp. sICAM-1 (r=-0.76, p<0.05) and vWF (r=-0.71, p<0.05) correlated negatively with insulin sensitivity, but not with skin microcirculatory parameters. CONCLUSIONS Acute hyperinsulinaemia, both with and without concomitant hyperglycaemia, does not increase skin microvascular permeability, haemodynamics or parameters of endothelial dysfunction in Type II diabetic patients. Furthermore, these data suggest that the coexistence of hyperinsulinaemia and endothelial dysfunction in Type II diabetes does not indicate a causal relationship, but may rather indicate decreased insulin sensitivity as a common underlying cause.

Abstract
The endothelium-derived vasoconstrictor molecule endothelin-1 (ET-1) has been suggested to play a role in the pathogenesis of Raynaud’s phenomenon (RP) and systemic sclerosis (SSc). We studied the effect of bosentan on microvascular structure and function in patients with RP secondary to limited cutaneous SSc in a mechanistic pilot study. In this single center, open study, 15 patients with limited cutaneous SSc were treated with bosentan for 16 weeks with a follow-up period of 4 weeks. Changes in microvascular structure and function were studied with assessment of vasodilatory microvascular responses using laser Doppler fluxmetry combined with iontophoresis, capillary permeability using fluorescence videomicroscopy, nailfold capillary microscopy, and serological markers of endothelial activation. No significant changes were seen in vasodilator responses to acetylcholine and sodium nitroprusside following bosentan treatment. No effect was noted on capillary permeability during treatment. The number of nailfold capillaries remained unchanged. The endothelial activation marker vascular cell adhesion molecule did not change during treatment, but levels of thrombomodulin significantly decreased after 12 weeks of treatment. Bosentan did not induce significant changes in vasodilator responses, capillary permeability, and capillary density during treatment, so no evidence was obtained for structural improvement of microvascular structure and function in this short-time mechanistic pilot study in patients with lcSSc.

Abstract
Diabetic angiopathy is a major cause of morbidity and mortality in diabetes mellitus. Endothelial dysfunction and associated alterations in blood flow, pressure and permeability are widely accepted phenomena in the diabetic milieu and are understood to lead to microangiopathy. Despite the clinical importance of diabetic microangiopathy, the mechanisms of pathogenesis remain elusive. In particular, much is yet to be understood about the nature of the putative increased permeability with respect to diabetes. Microvessel permeability is intrinsically difficult to measure and a surrogate (solute or solvent flux) is usually reported, the measurement of which is hampered by haemodynamic factors, such as flow rate, hydrostatic pressure gradient, solute concentration and surface area available for exchange. Very few studies describing the measurement of permeability with respect to diabetes have controlled for all these factors. As a result, the nature of the increased microvessel permeability in diabetes mellitus and indeed its causes are poorly understood. Recent studies have shown that hyperglycaemia can alter the glycocalyx structure, and parallel findings have shown that the apparent increase in permeability demonstrated in hyperglycaemia may be due to an increase in the permeability of the vessels to water, and not an increase in protein permeability, an effect attributable to altered glycocalyx. This review focuses on the current understanding of microvascular permeability in terms of the endothelial glycocalyx-fibre-matrix theory, those methods used to determine permeability in the context of diabetes, and the more recent developments in our understanding of elevated microvascular permeability in the diabetic circulation.

Abstract
Excretion of albumin in the urine is highly variable, ranging from nondetectable quantities to milligrams of albumin and even grams of albumin. Microalbuminuria is defined as low levels of urinary albumin excretion of 30 to 300 mg/d. Microalbuminuria is highly prevalent; in hypertensive and diabetic populations, its prevalence varies from 10 to 40%. It is interesting that microalbuminuria also is found frequently in seemingly healthy individuals (5 to 7%). The variable excretion of albumin in the urine is related to the risk for the individual to develop cardiovascular (CV) disease: Absence or very low levels of albuminuria is associated with low CV risk, whereas the CV risk increases markedly with increasing amount of albumin in the urine (even within the now considered normal range). The predictive power of urinary albumin levels for CV risk is independent of other CV risk factors and not only is present in individual with diabetes and/or hypertension but also in healthy individuals. Treatments that lower albuminuria are associated with CV protection, as demonstrated in randomized, controlled trials of patients with diabetes as well as in patients with hypertension. There is preliminary evidence that albuminuria lowering is CV protective in healthy individuals with an elevated albumin excretion rate. Differences between individuals in their level of albumin excretion are already observed at a very early age (just after birth). In fact, the interindividual variability seems to be relatively constant in the first 5 decades of life, indicating that microalbuminuria is not necessarily a consequence of vascular damage at later age. Higher levels of urinary albumin seem to reflect the ordinary interindividual variability in (renal and systemic) endothelial function. Experimental data show that between strains and even within strains, rats at young age show a remarkable difference in individual endothelial function, and this is strongly related to the susceptibility of that rat to organ damage. In conclusion, albuminuria seems to be a sensitive marker very early in life for the susceptibility of an individual to CV disease. It therefore may be an ideal target for early primary prevention using CV-protective therapy regimens.

Abstract
AIMS/HYPOTHESIS A loss of sympathetic function could lead to changes in capillary fluid filtration in diabetic patients. We investigated whether a decreased sympathetically mediated vasomotion in the skin in diabetic patients with peripheral neuropathy is associated with an abnormal capillary leakage. METHODS Three matched groups were studied: 18 diabetic patients with documented peripheral neuropathy (DN), 18 diabetic patients without peripheral neuropathy (D), and 18 healthy control subjects (C). Sensory and motor nerve function of the distal extremities were assessed by standard neurography, and expressed in a sensory-motor nerve function score. Sympathetic vasomotion of the skin microcirculation was assessed by determining the power of blood flow variability in the low-frequency (0.02-0.14 Hz) band by spectral analysis of laser Doppler flowmetry at the median ankle. Skin capillary leakage was evaluated by sodium fluorescein videodensitometry at the same site of the foot. RESULTS Sympathetically mediated vasomotion of the foot skin microcirculation was lower in diabetic patients with documented peripheral neuropathy compared with diabetic patients without peripheral neuropathy and control subjects (p<0.001). Capillary sodium fluorescein leakage was larger in 18 diabetic patients with documented peripheral neuropathy than in diabetic patients without peripheral neuropathy (p<0.02) and C (p<0.005). Multiple regression analysis disclosed that a reduced sympathetically mediated vasomotion, together with a lower sensory-motor nerve function score, independently contributed to the variance in sodium fluorescein leakage, for 30% (p<0.001) and 17% (p<0.01), respectively. CONCLUSIONS A loss of sympathetic tone, apart from sensory-motor nerve dysfunction, seems to be a major determinant of an increased capillary permeability in diabetic patients with neuropathy.

Abstract
OBJECTIVE Several lines of evidence suggest that the GH-IGF-1 axis affects capillary permeability and angiogenesis. We evaluated skin capillary permeability and capillary density in GH-deficient adults, before and after GH replacement therapy. PATIENTS Seven normotensive, nondiabetic GH-deficient adults (two women) were matched with 14 control subjects. MEASUREMENTS Large-window videodensitometry with sodium fluorescein was performed in all subjects. Capillary permeability was expressed as the average relative light intensity over the first 7 min after the appearance of fluorescein in the skin capillaries; Iav(7). Skin capillary density was determined by counting the visualized capillaries and was expressed as n/mm2. The GH-deficient patients were restudied after 12 months of GH replacement therapy (2 U/day). RESULTS Both capillary permeability and capillary density were lower in untreated GH-deficient patients than in control subjects (median, interquartile range): Iav(7) in GH-deficient patients 47.1 (45.1-52.2)% vs. 57.5 (50.5-64.8)% in controls, P < 0.05; capillary density in GH-deficient patients 18 (12-24)/mm2 vs. 32 (26-36)/mm2 in controls, P < 0.05. GH treatment normalized plasma IGF-1 from 4.3 (1.0-13.4) to 22.2 (19.8-48.2) nmol/l (P < 0.05). Furthermore, both capillary permeability [Iav(7) 53.1 (48.8-58.4)%, P < 0.05] and capillary density [26 (17-34)/mm2, P < 0.05] increased to a level that was not different from that in control subjects. CONCLUSIONS The present study demonstrates that the growth hormone deficiency syndrome is associated with microvascular alterations, which are responsive to growth hormone replacement therapy.

Abstract
Uncomplicated Type 1 (insulin-dependent) diabetes mellitus is characterized by generalized vasodilatation. Its possible correlates, increased microvascular permeability and endothelial dysfunction, have been associated with long-term complications. The objective was to study the effects of acute hyperglycemia and hyperinsulinemia, both separately and in combination, on skin microvascular flow, capillary permeability, capillary recruitment, and endothelial dysfunction in Type 1 diabetes mellitus. Sixteen Type 1 diabetic patients (all normoalbuminuric, no (pre-)proliferative retinopathy) underwent a euglycemic (glucose target 5.0 mmol/L, insulin infused at 30 mU x kg(-1) x h(-1)), a hyperglycemic (glucose target 12.0 mmol/L, insulin 30 mU x kg(-1) x h(-1)), a hyperinsulinemic (glucose target 5.0 mmol/L, insulin 150 mU x kg(-1) x h(-1)), and a hyperglycemic-hyperinsulinemic (glucose target 12.0 mmol/L, insulin 150 mU x kg(-1) x h(-1)) clamp on separate days, in random order. Skin microvascular flow was measured by laser Doppler flowmetry. Capillary permeability and density were determined by large-window sodium-fluorescein videodensitometry. Increases in serum soluble intercellular adhesion molecule-1 (sICAM-1) and plasma von Willebrand factor antigen (vWF-Ag) were considered to represent abnormal endothelial function. Hyperglycemia (P < 0.01) and hyperinsulinemia (P < 0.05) as well as both interventions combined (P < 0.001) induced an increase in laser Doppler flow, without capillary recruitment. Transcapillary leakage of sodium-fluorescein and sICAM-1 and vWF-Ag levels were unaffected by hyperglycemia or hyperinsulinemia. Microvascular permeability appears to be determined primarily by properties of the capillary wall and not by acute changes in local hemodynamics. The acute hyperglycemia- and hyperinsulinemia-induced vasodilatation is not accompanied by changes in microvascular permeability or endothelial markers.
