Endocr Metab Immune Disord Drug Targets 2021 Jan 4. Epub 2021 Jan 4.

Department of Nutrition, School of Health, Qazvin University of Medical Science, Qazvin, Iran; 7Metabolic Diseases Research Center, Qazvin University of Medical Sciences, Qazvin. Iran.

Background: Curcumin demonstrated many pharmacological effects including antioxidants, anti-inflammation, eliminating free radicals, anti-tumor, lipid regulation, and anti-coagulation.

Objective: This study aimed to assess and compare curcumin and nano-curcumin effects on lipid profile, oxidative stress, and inflammatory factors related to patients 'heart.

Method: This randomized, double-blind, placebo-controlled clinical trial was conducted on 90 patients undergoing coronary elective angioplasty which were randomly divided into 3 groups. The doses administered for 8 weeks were a 500 mg capsule of curcumin daily for the first group and an 80 mg capsule of nano-curcumin for the second group. However, the placebo group received capsules like curcumin. Lipid profile, oxidative stress factors, and inflammatory markers were measured at the baseline and end of the experiment.

Results: Statistically significant changes were observed in the total cholesterol (TC), triacylglycerol (TG) and low-density lipoprotein cholesterol (LDL-C) in the intervention groups to the control group (p<0.05). Curcumin and nano-curcumin supplementation also improved significant changes in plasma levels of total antioxidant capacity (TAC), malondialdehyde (MDA), Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), high-sensitivity C-reactive protein (hs-CRP), Interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in comparison to the placebo (p<0.05). Furthermore, the nano-curcumin group compared to the curcumin group demonstrated significant changes (p<0.05) in TC, TG, SOD, MDA and TNF-α levels.

Conclusion: The effects of curcumin on nano formula may be better for cardiac patients due to its high bioavailability.

Bronchodilatory effects of B-type natriuretic peptide in acute asthma attacks: a randomized controlled clinical trial.

Adv Respir Med 2020 ;88(6):531-538

Biostatistics Department, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Khouzestan, Iran.

Introduction: B-type natriuretic peptide (BNP) regulates different physiological processes such as blood pressure, cardiac growth, and neural and skeletal development. Thus, the aim of this study w as to evaluate the effect of BNP in the treatment of acute asthma attacks.

Material And Methods: In this randomized clinical trial, patients with acute asthma attacks were enrolled. The patients were divided randomly into two groups. Patients in the interventional group received BNP via intravenous infusion. Two µg/kg of BNP was injected as a bolus in 60 seconds. Then, infusion of BNP immediately began and was given in 0.01, 0.02, and 0.03 µg/kg/min doses every 30 minutes for the first 1.5 hours. The patients in the control group received nebulized salbutamol. Afterwards, peak flow meter findings, hemodynamic parameters, and estimation of the clinical severity of asthma in both groups were checked every 30 minutes.

Results: In total, 40 patients were included in this study. The values of PEFR in the 60th and 90th minutes in the control group were lower than those in the interventional group. In the 60th minute, the mean of PEFR was 377.3 in the BNP group but 335.95 in the control group (P = 0.049). Moreover, this difference remained significant in the 90th minute (P = 0.021). However, forced expiratory volume in one second (FEV1) did not differ between the groups at any time (p > 0.05).

Conclusion: Although a large experimental study is needed to verify our hypothesis, it seems that BNP might be a therapeutic option in asthma exacerbations, particularly in those with b2 agonist receptor polymorphism.

Prevention of Contrast-induced Nephropathy in Patients with Chronic Kidney Disease Undergoing Elective Coronary Angioplasty or Angiography with Sodium Potassium Citrate Solution, a Double Blind Randomized Clinical Trial.

Iran J Kidney Dis 2019 05;13(3):182-190

1Chronic Renal Failure Research Center, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Introduction: Contrast-induced nephropathy (CIN) is a frequent complication of contrast exposure. A recent study suggested that Na/K citrate might have a preventive role. We investigated the efficacy of Na/K citrate to prevent CIN in patients with renal dysfunction undergoing coronary intervention.

Methods: The randomized, double-blind, placebo-controlled trial included 201 patients with estimated creatinine clearance < 90 mL/ min, randomized to receive oral Na/K citrate plus saline infusion (treatment group, 104 patients) or oral water plus saline infusion (placebo group, 97 patients). CIN was defined as an absolute increase of serum creatinine ≥ 0.5 mg/dL or a relative increase ≥ 25% or a relative decrease of estimated GFR ≥ 25% within 5 days.

Results: CIN occurred in 22 patients (12.29%); 10 (11%) in treatment group and 12 (13.6%) in placebo group (P > .05). Post-exposure Cr values were not significantly different between the two groups (1.18 ± 0.28 mg/dL in the placebo vs. 1.15 ± 0.29 mg/dL in the treatment group, P > .05). CIN-negative patients in the treatment group showed a significantly higher increase in urine pH than that of CIN-positive patients (1.642 ± 0.577 vs. 1.20 ± 0.422, P < .05).

Conclusion: Na/K citrate solution is not effective for prophylaxis of CIN in patients with renal dysfunction. However, a probable preventive effect might exist in a subgroup of patients with at least 1.6 units increase in urine pH values following Na/K citrate administration.

Cytomegalovirus infection and atherosclerosis in candidate of coronary artery bypass graft.

Jundishapur J Microbiol 2015 Mar 21;8(3):e15476. Epub 2015 Mar 21.

Health College, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, IR Iran.

Background: Although there is enough evidence that infectious agents such as Chlamydia pneumonia and Helicobacter pylori may play a pathogenic role in atherosclerosis, this role for cytomegalovirus (CMV) is yet controversial.

Objectives: The aim of the present study was to detect CMV-DNA in atherosclerotic plaques in patients who underwent coronary artery bypass graft (CABG).

Patients And Methods: In this case-control study, candidates for CABG (cases) and patients with valvular or congenital malformation but without atherosclerotic plaques (controls) were studied from 2012 to 2013 at Golestan hospital, Ahvaz, IR Iran. Demographic and laboratory data were collected. Atherosclerotic and histological samples were obtained from visible plaques and from aorta by the surgeon. All the samples were examined for the presence of CMV-DNA by polymerase chain reaction (PCR) method using a commercial kit (SinaClon, Tehran, IR Iran).

Results: The mean ages in case and control groups were 60.8 ± 6.8 and 57.5 ± 11.5 years, respectively, with no significant difference (P = 0.09). Thirty patients (54.5%) in case and 32 (58.2%) in control groups were male with no significant difference (P = 0.7). CMV-DNA was present in 8 (14.5%) of the cases and 2 (4%) of the controls. CMV-DNA was associated with higher risk of atherosclerosis (OR: 7.7, 95% CI = 1.1-51.4, P = 0.03). Of the total normal aortic samples (55 in cases and 55 in controls), there was no individual with simultaneous positive CMV-DNA among aortic atherosclerotic and normal tissue samples.

Conclusions: The presence of CMV-DNA in aortic plaques is associated with increased risk of atherosclerosis. CMV infection may be considered as an independent risk factor for this event.

Clinical, high resolution computed tomography and pulmonary function in sulphur mustard victims.

Acta Med Iran 2012 ;50(9):603-8

Department of Internal Medicine, Ahwaz Jundishapur University of Medical Sciences, Ahwaz, Iran.

We aimed to evaluate clinical, high resolution computed tomography (HRCT) and pulmonary function test (PFT) findings after 18-23 years of exposure in veterans of sulphur mustard (SM) exposure. We performed a cross-sectional study of 106 patients. Inclusion criteria were 1: documented exposure to SM as confirmed by toxicological analysis of their urine and vesicular fluid after exposure 2: single exposure to SM that cause skin blisters and subsequent transient or permanent sequel. Cigarette smoking and pre-exposure lung diseases were of exclusion criteria. After taking history and thorough respiratory examination, patients underwent high resolution computed tomography and spirometry. Clinical diagnoses were made considering the findings. More than 85% of the patients were complaining of dyspnea and cough. Obstructive pattern (56.6%) was main finding in spirometry followed by restrictive and normal patterns. HRCT revealed air trapping (65.09%) and mosaic parenchymal attenuation patterns (58.49%) as most common results. Established diagnoses mainly were chronic obstructive pulmonary disease (COPD) (54.71%), bronchiolitis obliterans (27.35%) and asthmatic bronchitis (8.49%). There were not any significant association between the clinical findings and results of PFT and HRCT imaging and also between PFT and HRCT findings (P-values were more than 0.05). Considering debilitating and progressive nature of the respiratory complications of SM exposure, attempts are needed for appropriate diagnosis and treatment.
