Abstract
Unpolarized and beam-polarized fourfold cross sections (d^{4}σ/dQ^{2}dx_{B}dtdϕ) for the ep→e^{'}p^{'}γ reaction were measured using the CLAS detector and the 5.75-GeV polarized electron beam of the Jefferson Lab accelerator, for 110 (Q^{2},x_{B},t) bins over the widest phase space ever explored in the valence-quark region. Several models of generalized parton distributions (GPDs) describe the data well at most of our kinematics. This increases our confidence that we understand the GPD H, expected to be the dominant contributor to these observables. Through a leading-twist extraction of Compton form factors, these results support the model predictions of a larger nucleon size at lower quark-momentum fraction x_{B}.

Abstract
A reliable, low-cost and easy-to-use ELIME (Enzyme-Linked-Immuno-Magnetic-Electrochemical) assay for detection of Salmonella enterica in irrigation water is presented. Magnetic beads (MBs), coupled to a strip of eight-magnetized screen-printed electrodes localized at the bottom of eight wells (8-well/SPE strip), effectively supported a sandwich immunological chain. Enzymatic by-product is quickly measured by chronoamperometry, using a portable instrument. With the goal of developing a method able to detect a wide range of Salmonella serotypes, including S. Napoli and S. Thompson strains responsible for various community alerts, different kinds of MBs, antibodies and blocking agents were tested. The final system employs MBs coated with a broad reactivity monoclonal antibody anti-salmonella and blocked with dry milk. For a simple and rapid assay these two steps were performed in a preliminary phase, while the two sequential incubations for the immuno-recognition events were merged in a single step of 1h. In parallel a Real-Time PCR (RTi-PCR) method, based on a specific locked nucleic acid (LNA) fluorescent probe and an internal amplification control (IAC), was carried out. The selectivity of the ELIME and RTi-PCR assays was proved by inclusivity and exclusivity tests performed analyzing different Salmonella serotypes and non-target microorganisms, most commonly isolated from environmental sources. Furthermore, both methods were applied to experimentally and not experimentally contaminated irrigation water samples. Results confirmed by the ISO culture method, demonstrated the effectiveness of ELIME and RTi-PCR assays to detect a low number of salmonella cells (1-10 CFU/L) reducing drastically the long analysis time usually required to reveal this pathogen.

Abstract
STUDY OBJECTIVE To evaluate the effect of acarbose on glycemic control and glycemic variability, using a continuous glucose-monitoring system, in patients with type 2 diabetes mellitus who were not well controlled on metformin and vildagliptin therapy. DESIGN Multicenter, randomized, double-blind, placebo-controlled study. SETTING Clinical research units at three hospitals in Italy. PATIENTS Fifty-three patients with type 2 diabetes who were taking stable dosages of metformin 850 mg 3 times/day and vildagliptin 50 mg twice/day for at least 3 months and who were not adequately controlled with these therapies. INTERVENTION Patients were randomized to either placebo or acarbose 100 mg 3 times/day to be added to their metformin-vildagliptin regimen. MEASUREMENTS AND MAIN RESULTS Glycemic excursions were assessed by using a continuous glucose-monitoring system for 1 week. Glycemic control was estimated as the mean blood glucose (MBG) level, the area under the glucose concentration-time curve for a glucose level above 70 mg/dl (AUC above 70) or 180 mg/dl (AUC above 180), and the percentage of time that the glucose level was above 70 mg/dl (T above 70) or 180 mg/dl (T above 180). Intraday glycemic variability was assessed by the standard deviation of the blood glucose level, the mean amplitude of glycemic excursions (MAGE), the M value, and continuous overlapping net glycemic action. Day-to-day glycemic variability was assessed as the mean of daily difference (MODD). The MBG level was ~20 mg/dl lower in the acarbose group than in the placebo group (p<0.05), particularly during the postprandial period. The AUC above 70 did not significantly differ between the two groups, whereas the AUC above 180 was ~40% lower in the acarbose group than in the placebo group during the daytime (p<0.01). The T above 180 was significantly higher in the placebo group than in the acarbose group (31% vs 8%, p<0.01. Moreover, the standard deviation and MAGE values were significantly lower in the acarbose group. The MODD value was not significantly changed in either group, and no significant differences were recorded between groups. All adverse events were mild in both groups, with only a significantly greater frequency of flatulence noted in the acarbose group (5% with acarbose vs 0.5% with placebo, p<0.05). CONCLUSION The addition of acarbose to metformin and vildagliptin background therapy in patients with inadequately controlled type 2 diabetes decreased intraday glycemic variability, especially postprandial variability, but it was not associated with a significant change in interday glycemic variability.

Abstract
AIM To evaluate the effects on glycemic excursions during bicarbonate dialysis (BHD) compared to hemodiafiltration (HDF) in type 2 diabetic or not diabetic patients affected by end-stage renal disease (ESRD). MATERIAL AND METHODS Thirty-six patients (20 affected by type 2 diabetes mellitus, and 16 not diabetic patients) were evaluated and underwent BHD dialysis, followed by HDF dialysis two days later. All patients underwent also glucose continuous monitoring system, using iPro Continuous Glucose Monitor System (Medtronic MiniMed) starting just before the BHD, and ending five days later, two days after the HDF dialysis. Glycemic control was estimated as the mean blood glucose (MBG), the area under the glucose curve above 70mg/dl (AUC>70) or 180mg/dl (AUC>180), and the percentage of time above 70mg/dl (t>70) or 180mg/dl (t>180). Intraday glycemic variability was assessed as the standard deviation (SD), M value, and the mean amplitude of glycemic excursions (MAGE). Day-to-day glycemic variability was assessed as the mean of daily difference (MODD), that is the mean of the absolute difference among glucose values taken on 2 consecutive days at the same time. RESULTS glycemic control was better with HDF: MBG, and AUC>180 were lower during HDF compared do BHD. We also observed a significant decrease of glycemic excursions during HDF dialysis: SD, M value, and the MAGE value were lower with HDF. The MODD value was significantly changed in BHD group, while no differences were recorded during HDF. CONCLUSION HDF seems to greater reduce glycemic excursions during the treatment compared to BHD.

Abstract
UNLABELLED The aim of this study was to evaluate the effects of perindopril or barnidipine alone or combined with simvastatin on metabolic parameters and hepatic steatosis degree. One hundred and forty nine mild to moderate hypertensive, normocholesterolemic, overweight or obese outpatients with hepatic steatosis were enrolled. They were treated with perindopril 5mg/day, or barnidipine, 20mg/day, for 6 months; subsequently simvastatin, 20mg/day was added to both treatments for further 6 months. Blood pressure variation was recorded. Patients also underwent an ultrasound examination, at baseline and after 6, and 12 months. We also assessed: fasting plasma glucose (FPG), fasting plasma insulin (FPI), lipid profile, adiponectin (ADN), tumor necrosis factor-α (ΤΝF-α), interleukin-6 (IL-6), high-sensitivity C reactive protein (Hs-CRP). Both perindopril and barnidipine reduced blood pressure, with barnidipine being more effective. Barnidipine, but not perindopril, slightly decreased total cholesterol and triglycerides after 6 months compared to baseline; lipid profile improved in both groups when simvastatin was added. Regarding inflammatory parameters, barnidipine reduced TNF-a, IL-6, and Hs-CRP, both in monotherapy, and after simvastatin addition. Hepatic steatosis parameters improved only when simvastatin was added. We can conclude that barnidipine better reduced blood pressure compared to perindopril and inflammatory parameters. Regarding hepatic steatosis parameters, only the addition of simvastatin improved them. REGISTRATION NUMBER NCT02064218, ClinicalTrials.gov.

Nephrolithiasis, kidney failure and bone disorders in Dent disease patients with and without CLCN5 mutations. SPRINGERPLUS 2015; 4:492. [PMID: 26389017 PMCID: PMC4571032 DOI: 10.1186/s40064-015-1294-y] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/19/2015] [Accepted: 08/31/2015] [Indexed: 12/18/2022]
Abstract
Dent disease (DD) is a rare X-linked recessive renal tubulopathy characterised by low-molecular-weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis and/or nephrolithiasis. DD is caused by mutations in both the CLCN5 and OCRL genes. CLCN5 encodes the electrogenic chloride/proton exchanger ClC-5 which is involved in the tubular reabsorption of albumin and LMW proteins, OCRL encodes the inositol polyphosphate 5-phosphatase, and was initially associated with Lowe syndrome. In approximately 25 % of patients, no CLCN5 and OCRL mutations were detected. The aim of our study was to evaluate whether calcium phosphate metabolism disorders and their clinical complications are differently distributed among DD patients with and without CLCN5 mutations. Sixty-four male subjects were studied and classified into three groups: Group I (with CLCN5 mutations), Group II (without CLCN5 mutations) and Group III (family members with the same CLCN5 mutation). LMWP, hypercalciuria and phosphaturic tubulopathy and the consequent clinical complications nephrocalcinosis, nephrolithiasis, bone disorders, and chronic kidney disease (CKD) were considered present or absent in each patient. We found that the distribution of nephrolithiasis, bone disorders and CKD differs among patients with and without CLCN5 mutations. Only in patients harbouring CLCN5 mutations was age-independent nephrolithiasis associated with hypercalciuria, suggesting that nephrolithiasis is linked to altered proximal tubular function caused by a loss of ClC-5 function, in agreement with ClC-5 KO animal models. Similarly, only in patients harbouring CLCN5 mutations was age-independent kidney failure associated with nephrocalcinosis, suggesting that kidney failure is the consequence of a ClC-5 dysfunction, as in ClC-5 KO animal models. Bone disorders are a relevant feature of DD phenotype, as patients were mainly young males and this complication occurred independently of age. The triad of symptoms, LMWP, hypercalciuria, and nephrocalcinosis, was present in almost all patients with CLCN5 mutations but not in those without CLCN5 mutations. This lack of homogeneity of clinical manifestations suggests that the difference in phenotypes between the two groups might reflect different pathophysiological mechanisms, probably depending on the diverse genes involved. Overall, our results might suggest that in patients without CLCN5 mutations several genes instead of the prospected third DD underpin patients’ phenotypes.

Abstract
BACKGROUND We compared the changes in cell morphology, total and differential cell counts between cerebrospinal fluid (CSF) samples analyzed within an hour of collection (fresh sample) and after the addition of autologous serum and storage for 24 h (stored sample) in 27 cattle with central nervous system disorders. RESULTS There was a positive linear correlation between total and differential cell counts in the fresh and the stored samples. Cell morphology was preserved in all stored samples, except for increased vacuolization of mononuclear cells and cleaved nuclei of some small mononuclear cells. In the stored CSF samples, the total nucleated cell count and monocyte percentage were decreased (P = 0.01; P = 0.03), while the lymphocyte percentage was increased (P = 0.04). Mononuclear pleocytosis diagnosed in 20 fresh samples was cytologically confirmed in 12 of the 20 stored samples. In the remaining eight stored samples, the number of total nucleated cells was within the normal range. Neutrophilic pleocytosis was confirmed in all seven stored samples. The overall agreement rate between cytologic interpretation of the fresh and the stored CSF samples was 70 % (100 % for neutrophilic pleocytosis and 60 % for mononuclear pleocytosis). CONCLUSIONS Adding 11 % of autologous serum to CSF samples might allow delayed analysis with a good agreement rate for CSF cytological interpretation. Caution is nonetheless warranted, as animal age, anamnesis, and neurological presentation need to be considered when interpreting stored CSF without pleocytosis.

Abstract
The aim of this study was to evaluate the effects of lercanidipine or barnidipine on echocardiographic parameters, in hypertensive, type 2 diabetics with left ventricular hypertrophy. One hundred and forty-four patients were randomized to lercanidipine, 20 mg/day, or barnidipine, 20 mg/day, in addition to losartan, 100 mg/day, for 6 months. We evaluated: blood pressure, fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), lipid profile, creatinine, estimated glomerular filtration rate (eGFR), sodium, potassium, and acid uric. Echocardiography was performed at baseline and after 6 months. Both lercanidipine and barnidipine decreased blood pressure. Left ventricular mass index was reduced to a greater extent with barnidipine + losartan. Interventricular septal thickness in diastole was reduced by barnidipine + losartan. Posterior wall thickness in diastole was decreased by both treatments, even if barnidipine + losartan were more effective. Ratio of peak early diastolic filling velocity to peak filling velocity at atrial contraction was increased by barnidipine + losartan, but not by lercanidipine + losartan. Finally, isovolumetric relaxation and time and left atrial volume index were reduced by barnidipine + losartan, while lercanidipine + losartan did not affect them. In conclusion, barnidipine + losartan provided a greater improvement of echocardiographic parameters compared to lercanidipine + losartan.

Abstract
AIM To evaluate the relevance of adding acetylsalicylic acid (ASA) in primary prevention in subjects with type 2 diabetes mellitus. METHODS 213 patients with type 2 diabetes mellitus and hypertension were randomized to amlodipine 5 mg, or amlodipine 5 mg + ASA 100 mg for 3 months (Phase A); then, if adequate blood pressure control was reached patients terminated the study; otherwise, amlodipine was up-titrated to 10 mg/day for further 3 months and compared to amlodipine 10 mg + ASA 100 mg (Phase B). We assessed at baseline, at the end of Phase A, and at the end of Phase B the levels of some new emerging biomarkers of cardiovascular risk including: high sensitivity C-reactive protein (Hs-CRP), adiponectin (ADN), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), myeloperoxidase (MPO), soluble CD40 ligand (sCDL40). RESULTS Compared to baseline, at the end of Phase A, patients treated with amlodipine 5 mg + ASA 100 mg showed a statistically significant reduction of Hs-CRP (-15.0%), TNF-α (-21.7%), MPO (-9.7%), and sCDL40 (-15.7%), and a statistically significant increase of ADN (+15.0%). These values were significantly better than the ones obtained with amlodipine alone. Similarly, at the end of Phase B, amlodipine 10 mg + ASA significantly lowered Hs-CRP (-18.8%), TNF-α (-15.0%), MPO (-9.2%), and sCDL40 (-20.0%) and increased ADN (+11.8%), with a better effect compared to amlodipine alone. CONCLUSION All biomarkers considered were significantly improved by ASA addition. These data suggest that the use of ASA in primary prevention could be useful in patients with type 2 diabetes mellitus and hypertension. TRIAL REGISTRATION ClinicalTrials.gov: NCT02064218.

Abstract
AIM To compare, using a continuous glucose monitoring (CGM) system, the effect on glycaemic variability of insulin glargine, detemir and lispro protamine. METHODS A total of 49 white people with type 1 diabetes, not well controlled by three times daily insulin lispro, taken for at least 2 months before study and on a stable dose, were enrolled. The study participants were randomized to add insulin glargine, detemir or lispro protamine, once daily, in the evening. We used a CGM system, the iPro Digital Recorder (Medtronic MiniMed, Northridge, CA, USA) for 1 week. Glycaemic control was assessed according to mean blood glucose values, the area under the glucose curve above 3.9 mmol/l (AUC(>3.9)) or above 10.0 mmol/l (AUC(>10.0)), and the percentage of time spent with glucose values >3.9 or >10.0 mmol/l. Intraday glycaemic variability was assessed using standard deviation (s.d.) values, the mean amplitude of glycaemic excursions and continuous overlapping of net glycaemic action. Day-to-day glycaemic variability was assessed using the mean of daily differences. RESULTS The s.d. was found to be significantly lower with insulin lispro protamine and glargine compared with insulin detemir. AUC(>3.9) was higher and AUC(>10.0) was lower with insulin lispro protamine and glargine compared with detemir. The mean amplitude of glycaemic excursions and continuous overlapping net glycaemic action values were lower with insulin lispro protamine and glargine compared with detemir. In addition, the mean of daily differences was significantly lower with insulin lispro protamine and glargine compared with detemir. Fewer hypoglycaemic events were recorded during the night-time with insulin lispro protamine compared with glargine and detemir. CONCLUSIONS The results suggest that insulin lispro protamine and glargine are more effective than detemir in reducing glycaemic variability and improving glycaemic control in people with type 1 diabetes. Insulin lispro protamine seems to lead to fewer hypoglycaemic events than other insulin regimens.

Abstract
AIM The aim of this study was to evaluate the prevalence of erectile dysfunction (ED) in a sample of type 2 diabetic patients. As secondary endpoint, we evaluated the levels of some adipocytokines in patients with and without ED. MATERIAL AND METHODS We enrolled 220 males affected by type 2 diabetes mellitus. We administered the IIEF (International Index of Erectile Function), SAS (self-rating anxiety scale) and SDS (self-rating depression scale) questionnaires. We evaluated body mass index, glycemic control, fasting plasma insulin (FPI), homeostasis model assessment of insulin resistance index (HOMA-IR), lipid profile, sexual hormones, adiponectin (ADN), resistin, retinol binding protein-4 (RBP-4), visfatin, vaspin. RESULTS 52.9% of patients were affected by ED. Patients with a HbA1c <7% (53 mmol/mol) in all measurements in the two previous years had a lower incidence of ED, while the prevalence of ED increased with the increasing of times HbA1c was >7% (53 mmol/mol). Patients with ED had higher levels of triglycerides, and higher levels of FPI, 9.9 μU/ml vs 8.2 μU/ml (p<0.05). Resistin levels were higher in patients with ED compared to those without ED (p<0.05) and free testosterone was lower in patients affected by ED. CONCLUSIONS Almost half of type 2 diabetic patients attending our clinic were affected by ED and glycemic control seems to play a role in ED pathogenesis.

Abstract
Background Large animals have a relatively high seizure threshold, and in most cases seizures are acquired. No published case series have described this syndrome in cattle. Objectives To describe clinical findings and outcomes in cattle referred to the Veterinary Teaching Hospital of the University of Turin (Italy) because of seizures. Animals Client‐owned cattle with documented evidence of seizures. Methods Medical records of cattle with episodes of seizures reported between January 2002 and February 2014 were reviewed. Evidence of seizures was identified based on the evaluation of seizure episodes by the referring veterinarian or 1 of the authors. Animals were recruited if physical and neurologic examinations were performed and if diagnostic laboratory test results were available. Results Forty‐three of 49 cases fulfilled the inclusion criteria. The mean age was 8 months. Thirty‐one animals were male and 12 were female. Piedmontese breed accounted for 39/43 (91%) animals. Seizures were etiologically classified as reactive in 30 patients (70%) and secondary or structural in 13 (30%). Thirty‐six animals survived, 2 died naturally, and 5 were euthanized for reasons of animal welfare. The definitive cause of reactive seizures was diagnosed as hypomagnesemia (n = 2), hypocalcemia (n = 12), and hypomagnesemia‐hypocalcemia (n = 16). The cause of structural seizures was diagnosed as cerebrocortical necrosis (n = 8), inflammatory diseases (n = 4), and lead (Pb) intoxication (n = 1). Conclusion and Clinical Importance The study results indicate that seizures largely are reported in beef cattle and that the cause can be identified and successfully treated in most cases.

Abstract
AIM To evaluate the effects of Berberis aristata combined with Silybum marianum in dyslipidemic patients intolerant to statins at high doses. METHODS 137 euglycemic, dyslipidemic subjects, with previous adverse events to statins at high doses, were enrolled. Statins were stopped for 1 month (run-in), then they were re-introduced at the half of the previously taken dose. At randomization, patients tolerating the half dose of statin, were assigned to add placebo or B. aristata/S. marianum 588/105 mg, 1 tablet during the lunch and 1 tablet during the dinner, for six months. We evaluated lipid profile and safety parameters variation at randomization, and after 3, and 6 months. RESULTS B. aristata/S. marianum reduced fasting plasma glucose (-9 mg/dl), insulin (-0.7 μU/ml), and HOMA-index (-0.35) levels compared to baseline and also to placebo. Lipid profile did not significantly change after 6 months since the reduction of statin dosage and the introduction of B. aristata/S. marianum, while it worsened in the placebo group both compared to placebo and with active treatment (+23.4 mg/dl for total cholesterol, +19.6 mg/dl for LDL-cholesterol, +23.1 mg/dl for triglycerides with placebo compared to B. aristata/S. marianum). We did not record any variations of safety parameters in nether of groups. CONCLUSIONS B. aristata/S. marianum can be considered as addition to statins in patients not tolerating high dose of these drugs.

Abstract
Medullary nephrocalcinosis is a hallmark of medullary sponge kidney (MSK). We had the opportunity to study a spontaneous calcification process in vitro by utilizing the renal cells of a patient with MSK who was heterozygous for the c.-27 + 18G>A variant in the GDNF gene encoding glial cell-derived neurotrophic factor. The cells were obtained by collagenase digestion of papillary tissues from the MSK patient and from two patients who had no MSK or nephrocalcinosis. These cells were typed by immunocytochemistry, and the presence of mineral deposits was studied using von Kossa staining, scanning electron microscopy analysis and an ALP assay. Osteoblastic lineage markers were studied using immunocytochemistry and RT-PCR. Staminality markers were also analysed using flow cytometry, magnetic cell separation technology, immunocytochemistry and RT-PCR. Starting from p2, MSK and control cells formed nodules with a behaviour similar to that of calcifying pericytes; however, Ca2PO4 was only found in the MSK cultures. The MSK cells had morphologies and immunophenotypes resembling those of pericytes or stromal stem cells and were positive for vimentin, ZO1, αSMA and CD146. In addition, the MSK cells expressed osteocalcin and osteonectin, indicating an osteoblast-like phenotype. In contrast to the control cells, GDNF was down-regulated in the MSK cells. Stable GDNF knockdown was established in the HK2 cell line and was found to promote Ca2PO4 deposition when the cells were incubated with calcifying medium by regulating the osteonectin/osteopontin ratio in favour of osteonectin. Our data indicate that the human papilla may be a perivascular niche in which pericyte/stromal-like cells can undergo osteogenic differentiation under particular conditions and suggest that GDNF down-regulation may have influenced the observed phenomenon.

Abstract
AIM to evaluate the efficacy of Berberis aristata/Silybum marianum (Berberol(®)) in a sample of dyslipidemic patients intolerant to statins at high dosages in a randomized, double blind, placebo-controlled clinical trial. METHODS we enrolled 175 euglycemic, dyslipidemic subjects, intolerant to statins at high dosages. During the run-in period, statins were stopped for 1 month, then they were re-introduced at the half of the previously taken dose. After that, patients were randomized to placebo or Berberol(®), 1 tablet during the lunch and 1 tablet during the dinner, for 6 months. Anthropometric, metabolic and inflammatory parameters were assessed at randomization, at 3 and 6 months. RESULTS fasting plasma glucose, insulin, and HOMA-index levels were reduced by Berberol(®), but not by placebo; moreover they were lower than the ones recorded with placebo. Total cholesterol, LDL-C, triglycerides, and myeloperoxidase did not change after 6 months since the reduction of statin dosage and the introduction of Berberol(®), while they increased in the placebo group, and were higher compared to the ones obtained with active treatment. No patients had serious adverse events in both groups. CONCLUSIONS our study displays the rationale of the combination of Berberol(®) and a reduced dosage of statin for the treatment of hyperlipidemia in patients intolerant to statins at high dosage.

Abstract
There is a significant discrepancy between the values of the proton electric form factor, G(E)(p), extracted using unpolarized and polarized electron scattering. Calculations predict that small two-photon exchange (TPE) contributions can significantly affect the extraction of G(E)(p) from the unpolarized electron-proton cross sections. We determined the TPE contribution by measuring the ratio of positron-proton to electron-proton elastic scattering cross sections using a simultaneous, tertiary electron-positron beam incident on a liquid hydrogen target and detecting the scattered particles in the Jefferson Lab CLAS detector. This novel technique allowed us to cover a wide range in virtual photon polarization (ϵ) and momentum transfer (Q(2)) simultaneously, as well as to cancel luminosity-related systematic errors. The cross section ratio increases with decreasing ϵ at Q(2)=1.45 GeV(2). This measurement is consistent with the size of the form factor discrepancy at Q(2)≈1.75 GeV(2) and with hadronic calculations including nucleon and Δ intermediate states, which have been shown to resolve the discrepancy up to 2-3 GeV(2).

Abstract
AIM To evaluate the effects of canrenone compared to placebo on blood pressure control, some non-conventional biomarkers in cardiovascular stratification, and on metalloproteinases in patients affected by metabolic syndrome. METHODS A total of 156 Caucasian patients were treated with placebo or canrenone, 50 mg once a day, for 3 months and then 50 mg twice a day, till the end of the study. We evaluated: systolic (SBP) and diastolic blood pressure (DBP), body weight, body mass index (BMI), fasting plasma glucose (FPG), lipid profile, plasma aldosterone, creatinine, potassium, brain natriuretic peptide (BNP), metalloproteinases 2 and 9 (MMP-2 and -9), lipoprotein (a) (Lp(a)), and serum myeloperoxidase (MPO). RESULTS We observed a significant decrease of SBP and DBP in the canrenone group compared to baseline. Canrenone gave a significant decrease of MMP-2 and -9, Lp(a), and MPO compared to baseline, not observed with placebo. Plasma aldosterone, but not BNP, decreased with canrenone, both compared to baseline and to placebo. CONCLUSION Canrenone seems to be effective in reducing blood pressure in patients with metabolic syndrome. Moreover, canrenone seems also to improve MPO, Lp(a), and metalloproteinases in these patients.
