Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with an unknown aetiology. Although there is no definite treatment for this disease using proper prescribed medications, mortality and morbidity ratios could be decreased. The present study attempted to investigate adherence to medical treatment in patients suffering from SLE and to evaluate the related factors which influence adherence in order to improve patients’ prognoses. In this cross-sectional study, 132 patients with SLE who referred to the rheumatology clinic of Imam Khomeini Hospital (Tehran, Iran) over the period of 2012-2013 wereexamined using a questionnaire. The applied questionnaire included two parts; the first part pertained to adherence to medication treatments (CQR: compliance questionnaire rheumatology), and the second part was related to the factors involved in adherence to medication treatments. The obtained data were analyzed using the Chi-Square test and processed by SPSS16.0 software.In this research, the mean adherence to drug treatment was calculated to be 72.48%. Among the variables of age, marital status, salary, education, distance from the clinic (accessibility), disease duration, level of patient activity, main medications consumed, and side effects, the only significant association was found between adherence level and lack of side effects due to SLE (p

Introduction: Hyperlipidemia is considered a prominent risk factor for coronary heart disease. Coronary heart disease is the most common cause of mortality and morbidity in chronic kidney disease (CKD) patients. Objectives: The aim of this study was to evaluate the effects of artichoke leaf extract (ALE) supplementation on the lipid profile of CKD patients. Patients and Methods: A randomized, double-blind, placebo-controlled clinical trial was conducted in 38 CKD subjects (GFR15 mL/min/1.73 m2 ) with hypercholesterolemia (total cholesterol ≥ 200 mg/dL or low-density lipoprotein cholesterol [LDL-C] ≥ 110 mg/dL). The intervention group received an artichoke capsule (320 mg) and an indistinguishable placebo was given to the control group twice daily for 6 weeks. Lipid profile and appetite were assessed at week 8 and the results were compared with the baseline data. Results: ALE supplementation was correlated with a statistically significant decrease in mean total cholesterol (P=0.028) and LDL-C (P=0.005) compared to the control group. The two groups did not show a significant difference in high-density lipoprotein-cholesterol (P=0.071) and triglyceride levels (P=0.22). There was a statistically significant difference in appetite between the two groups (P=0.016). Conclusion: This randomized controlled trial demonstrated that consumption of ALE supplement may improve appetite and lipid profile in CKD patients.

OBJECTIVE: Serum albumin is a marker of malnutrition and inflammation and has been demonstrated as a strong predictor of mortality in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. Yet, whether serum albumin levels in late-stage CKD are associated with adverse outcomes after the transition to ESRD is unknown. We hypothesize that lower levels and a decline in serum albumin in late-stage CKD are associated with higher risk of mortality and hospitalization rates 1 year after transition to ESRD. DESIGN AND METHODS: This retrospective cohort study included 29,124 US veterans with advanced CKD transitioning to ESRD between 2007 and 2015. We evaluated the association of pre-ESRD (91 days before transition) serum albumin with 12-month post-ESRD all-cause, cardiovascular, and infection-related mortalities and hospitalization rates as well as the association of 1-year pre-ESRD albumin slope and 12-month post-ESRD mortality using hierarchical multivariable adjustments. RESULTS: There was a negative linear association between serum albumin and all-cause mortality, such that risk doubled (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.87, 2.28) for patients with the lowest serum albumin 0.25 g/dL/year was associated with reduced mortality risk (HR: 0.76, 95% CI: 0.63, 0.91) compared with a slight decline in albumin (ref: >−0.25 to 0 g/dL/year), whereas a decline more than 0.5 g/dL/year was associated with a 55% higher risk in mortality (HR: 1.55, 95% CI: 1.43, 1.68) in fully adjusted models. CONCLUSIONS: Lower pre-ESRD serum albumin was associated with higher post-ESRD all-cause, cardiovascular, and infection-related mortalities and hospitalization rates. Declining serum albumin levels in the pre-ESRD period were also associated with worse 12-month post-ESRD mortality.

Background Urinary tract infection (UTI) accounts for about half of all post- kidney transplant infections. There is conflicting data regarding vitamin C and UTI prevention. So far, its efficacy has not been studied in renal transplant patients. Methods Kidney transplant candidates were randomized between vitamin C and placebo arms. In the treatment group, patients received vitamin C infusion at a single dose of 70 mg/kg. In another study arm, only the diluent solution was administered. Data regarding bacteriuria during the first hospitalization after transplantation were recorded. Results A total of 19 patients were randomized to the placebo (n = 10) and vitamin C (n = 9) group. The rate of bacteriuria during the first hospitalization after transplantation was significantly lower in the vitamin C group than in the placebo group, 11.1% versus 60%, respectively. (P = 0.02). Conclusion Vitamin C as a safe treatment is a potential prophylactic agent in post kidney transplantation UTI.

Background Delayed graft function (DGF) can affect short- and long-term allograft outcomes in kidney transplant recipients. One of the pathophysiological pathways in the occurrence of DGF is ischemia-reperfusion injury (IRI). High dose intravenous vitamin C has proven efficacy in decreasing IRI consequences. Accordingly, we designed this study to assess the effect of high dose intravenous vitamin C on the incidence and duration of DGF. Methods This is a pilot, single-center, double-blinded, randomized, placebo-controlled trial. In the treatment group, kidney transplant recipients received vitamin C infusion at the dose of 70 mg/kg diluted in 0.45% saline, and in another study arm, only the diluent solution was administered. Data regarding allograft function and other clinical information was recorded. Results This preliminary study on 19 patients (9 cases in the vitamin C and 10 cases in the placebo group) showed that after administration of single, high dose vitamin C the incidence of DGF was not significantly different between the groups, but the duration of DGF was substantially shorter in the vitamin C group than the placebo group (7.33 ± 5.68 versus 19.66 ± 0.57 days; P = 0.02). Acute rejection episodes were more seen in the vitamin C group than in the placebo group. Although this data was not statistically significant (P = 0.37), it led to the termination of the study. Conclusion A high dose of intravenous vitamin C before allograft implantation was effective in decreasing DGF duration but not DGF incidence. Trial registration The trial was registered in the Iranian registry of clinical trials encoded IRCT20100111003043N13 on June 24, 2019.

Estimating glomerular filtration rate (eGFR) using different formulas is common clinical practice for evaluating kidney function and drug dosing. But, the performance of available eGFR equations is questionable during early days after kidney transplantation.This study compared the performance of three common eGFR equations (Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)) in relation with measured GFR (mGFR) using clearance of Tc-99m-diethylenetriaminepentaacetic acid, 7 to 10 days post kidney transplantation. Agreement of mGFR and different eGFR equations in the staging of kidney function and dosing of 8 common antimicrobials were assessed.Thirty kidney and 5 simultaneous pancreas-kidney transplant recipients were included. CG applying total body weight (CGTBW) had the lowest bias (-12 mL/min/ 1.73 m2) and the highest percentage of estimation within 30% of mGFR (71.4%). MDRD showed the best precision (13.14 mL/min/ 1.73m2) and linear correlation with mGFR. CKD-EPI and MDRD acted better than CG for staging the level of kidney function. CGTBW had the lowest discordance rate with mGFR for antimicrobials dosing (33.6%). Discordance rates of drug dosing between mGFR and eGFR formulas were greater for drugs that have higher dosing levels such as (val)-ganciclovir (≥ 54.3%).Until developing more accurate methods for estimating kidney function during first 1 to 2 weeks after kidney transplantation, CGTBW method is suggested for drug dose adjustment and MDRD or CKD-EPI equation for the staging of kidney function in these patients, keeping in mind that these formulas underestimate the level of kidney function in new transplant recipients.

Introduction: Delayed graft function (DGF) is associated with significant adverse outcomes in deceased donor kidney transplantation (KT) including lower graft survival. However, risk factors and potential preventive strategies like intraoperative rabbit antithymocyte globulin (rATG; thymoglobulin) have not yet been fully evaluated. Objectives: The aim of this study was to investigate DGF risk factors and determine the association of intraoperative rATG with the risk of DGF in deceased donor kidney recipients. Patients and Methods: We retrospectively examined medical records of 163 first time deceased donor kidney transplant recipients at two major kidney transplant centers from 2014 to 2016. All the donors were standard heart-beating, brain death donors. Risk factors for DGF in recipients were evaluated using multivariate logistic regression analysis. Results: The mean recipients’ age was 43±13 years and the majority of participants were male (64%). The overall rate of DGF was 27%. Intraoperative rATG was significantly associated with a lower rate of DGF (adjusted odds ratio [AOR], 0.33, 95% CI, 0.11-0.95). Intraoperative transfusion (AOR, 3.7, 95% CI, 1.4-9.9) and diabetes mellitus (AOR, 3.7, 95% CI, 1.5-8.9) were significantly associated with higher risk of DGF. Conclusion: This study showed that intraoperative blood transfusion and diabetes mellitus were associated with increased risk of DGF. Meanwhile, administration of intraoperative rATG was associated with reduced odds ratio of DGF. Future studies are needed to evaluate the potential role of rATG in DGF-related renal outcomes.

Summary Background and aim There are several observational and interventional studies regarding the advantages of sufficient serum levels of vitamin C and the evaluation of the effects of vitamin C supplementation post kidney transplantation. These studies have been put together to investigate the role of vitamin C post-kidney transplantation and make suggestions for designing future studies based on the use of vitamin C supplements or nutritional interventions among these patients. Methods This narrative review was done by searching in the Embase, PubMed, and SCOPUS databases. Results The results are presented in several sections as follows; nutritional status, potential protective effects, safety concerns, and medications/laboratory tests interactions of vitamin C. Conclusions: Kidney transplant recipients are prone to vitamin C deficiency, which is related to higher mortality based on several long-term observational studies. Vitamin C supplementation improves endothelial function and creatinine clearance. Vitamin C is considered as a safe supplement, however, side effects such as kidney stones, pro-oxidant effect, hemolysis in patients with glucose-6-phosphate dehydrogenase deficiency, impact on lymphocytic activity, acid-base disturbance, and increased sodium load following its administration have been reported. Interaction of vitamin C and cyclosporine is the most important interaction with post-renal transplant medications. Vitamin C also interferes with creatinine assay using Jaffe and enzymatic methods.

Background: Maternal hypertensive disorder is a well-known medical problem during pregnancy and is associated with morbidity and mortality. Out-of-office blood pressure (BP) measurement has been widely used but the importance of detecting white coat hypertension (WCH) is still a topic for debate. Objectives: The aim of this study was to determine the prevalence of WCH in high-risk pregnant women. Methods: We included 56 pregnant women with in-office higher-than-normal BP without previous history of HTN to assess their BP using 24-hour ambulatory blood pressure monitoring (ABPM). Results: The mean age of the participants was 31.61 ± 5.42 years (n = 56) and the majority in the second or third trimesters. Hypertension was detected in 55.4% using 24-hour ABPM. Twenty-five patients (44.6%) had WCH, 60% of whom were in the third trimester. There was a significant difference in the incidence of WCH between women younger than 30 and older individuals (P = 0.041). The mean age was 33.13 ± 5.16 years in patients with true HTN and 29.72 ± 5.22 years in WCH patients (P = 0.018). Conclusions: The prevalence of WCH in pregnancy is noteworthy. Regarding its favorable outcome, this might be a heads-up to avoid unnecessary medication during pregnancy and be concise about defining HTN in this population.

Serum albumin (sAlb) may be a strong predictor of longevity in the general population and in chronic kidney disease. This study aimed to determine the relationship between sAlb concentrations and mortality risk independent of kidney function.This was a retrospective cohort study of 31 274 adults from the 1999-2010 National Health and Nutrition Examination Survey. The estimated glomerular filtration rate (eGFR) was examined as both a confounder and modifier of the association of sAlb with mortality risk. We examined the association of sAlb (categorized as3.8, 3.8 to4.0, 4.0 to4.2, 4.2 to4.4, 4.4 to4.6, 4.6 to4.8, and ≥4.8 g/dL) with mortality using Cox models. Subsequently, we conducted spline analyses to estimate the association of sAlb with all-cause mortality across varying eGFR levels.In unadjusted analyses, participants with incrementally lower sAlb concentrations of4.6 g/dL had an increasingly higher mortality risk compared with those with sAlb levels ranging from 4.6 to4.8 g/dL (reference), whereas those with higher sAlb levels of ≥4.8 g/dL had a lower mortality risk (hazard ratios [95% confidence interval]: 3.88 [3.26-4.62], 3.59 [3.01-4.27], 2.79 [2.37-3.29], 2.10 [1.79-2.48], 1.72 [1.45-2.03], and 0.71 [0.55-0.92] for sAlb concentrations of3.8, 3.8 to4.0, 4.0 to4.2, 4.2 to4.4, 4.4 to4.6, and ≥4.8 g/dL, respectively). Adjusted analyses showed similar findings, although the association of higher sAlb levels of ≥4.8 g/dL with better survival was attenuated to the null. Spline analyses showed that participants with sAlb levels of4.6 g/dL had higher mortality across all concentrations of eGFR, ranging from 30 to 120 mL/min/1.73 mAmong a nationally representative U.S. cohort, a graded association was observed between lower sAlb concentrations and higher death risk, which was robust across varying levels of kidney function.

While obesity is associated with a variety of complications including diabetes, hypertension, cardiovascular disease and premature death, observational studies have also found that obesity and increasing body mass index (BMI) can be linked with improved survival in certain patient populations, including those with conditions marked by protein-energy wasting and dysmetabolism that ultimately lead to cachexia. The latter observations have been reported in various clinical settings including end-stage renal disease (ESRD) and have been described as the "obesity paradox" or "reverse epidemiology", engendering controversy. While some have attributed the obesity paradox to residual confounding in an effort to "debunk" these observations, recent experimental discoveries provide biologically plausible mechanisms in which higher BMI can be linked to longevity in certain groups of patients. In addition, sophisticated epidemiologic methods that extensively adjusted for confounding have found that the obesity paradox remains robust in ESRD. Furthermore, novel hypotheses suggest that weight loss and cachexia can be linked to adverse outcomes including cardiomyopathy, arrhythmias, sudden death and poor outcomes. Therefore, the survival benefit observed in obese ESRD patients can at least partly be derived from mechanisms that protect against inefficient energy utilization, cachexia and protein-energy wasting. Given that in ESRD patients, treatment of traditional risk factors has failed to alter outcomes, detailed translational studies of the obesity paradox may help identify innovative pathways that can be targeted to improve survival. We have reviewed recent clinical evidence detailing the association of BMI with outcomes in patients with chronic kidney disease, including ESRD, and discuss potential mechanisms underlying the obesity paradox with potential for clinical applicability.

Background There is accumulating evidence that serum levels of non–high‐density lipoprotein cholesterol (non– HDL ‐C) are a more accurate predictor of cardiovascular outcomes when compared with low‐density lipoprotein cholesterol. However, we recently found that higher serum concentrations of triglycerides are associated with better outcomes in patients undergoing hemodialysis. Therefore, we hypothesized that the association of serum levels of non– HDL ‐C (which includes triglyceride‐rich lipoproteins) with outcomes may also be different in patients undergoing hemodialysis when compared with other patient populations. Methods and Results We studied the association of baseline and time‐dependent serum levels of non– HDL ‐C with all‐cause and cardiovascular mortality using Cox proportional hazard regression models in a nationally representative cohort of 50 118 patients undergoing incident hemodialysis from January 1, 2007, to December 31, 2011. In time‐dependent models adjusted for case mix and surrogates of malnutrition and inflammation, a graded inverse association between non– HDL ‐C level and mortality was demonstrated with hazard ratios (95% confidence intervals) of the lowest (HDL ‐C levels HDL / HDL cholesterol ratio and mortality, with the highest all‐cause and cardiovascular mortality being observed in patients with decreased non‐ HDL / HDL‐C ratio ( Conclusions Contrary to the general population, decrements in non– HDL ‐C and non‐ HDL / HDL cholesterol ratio were paradoxically associated with increased all‐cause and cardiovascular mortality in patients undergoing incident hemodialysis. The underlying mechanisms responsible for these associations await further investigation.

Objectives This study was carried out to investigate the medical students’ attitudes towards early clinical exposure at Tehran University of Medical Sciences. Methods A cross-sectional study was conducted during 2012-2015. A convenience sample of 298 first- and second-year students, enrolled in the undergraduate medical curriculum, participated in an early clinical exposure program. To collect data from medical students, a questionnaire consisting of open-ended questions and structured questions, rated on a five-point Likert scale, was used to investigate students’ attitudes toward early clinical exposure. Results Of the 298 medical students, 216 (72%) completed the questionnaires. The results demonstrated that medical students had a positive attitude toward early clinical exposure. Most students (80.1%) stated that early clinical exposure could familiarize them with the role of basic sciences knowledge in medicine and how to apply this knowledge in clinical settings. Moreover, 84.5% of them believed that early clinical exposure increased their interest in medicine and encouraged them to read more. Furthermore, content analysis of the students’ responses uncovered three main themes of early clinical exposure, were considered helpful to improve learning: “integration of theory and practice”, “interaction with others and professional development” and “desire and motivation for learning medicine”. Conclusions Medical students found their first experience with clinical setting valuable. Providing clinical exposure in the initial years of medical curricula and teaching the application of basic sciences knowledge in clinical practice can enhance students’ understanding of the role they will play in the future as a physician.

Complex regional pain syndrome type 1 (CRPS1) refers to a disorder usually caused by trauma; it is characterized by pain, swelling, limited range of motion, vasomotor instability, skin changes, joint stiffness, and patchy bone demineralization. Most often it occurs after trauma. Other etiologies include myocardial ischemia, cerebrovascular accidents, infection and emotional stress. We report a case of bilateral CRPS1 of the upper extremities in a 52-year-old woman suffering from major depressive disorder. She was complaining about her hands' stiffness and pain. She also reported swelling of both upper extremities and anhydrosis, thickening of the skin and muscle wasting, finger movement limitation, contracture of the digits and trophic skin changes. The diagnosis of CRPS1 was suspected, according to history, physical examination, radiographic changes and bone scintigraphy.

Objective: Delayed graft function (DGF) is an early complication after kidney transplantation with negative impact on allograft outcomes. This study assessed the effect of delayed initiation of tacrolimus as a nephrotoxic drug, on DGF occurrence and allograft function. Methods: This randomized, open-label clinical trial was conducted on kidney transplant recipients with the age of at least 14 years who underwent the first kidney transplantation from deceased or living donor. Patients were randomly allocated to immediate (n = 26) or delayed tacrolimus (n = 27) groups. All patients received thymoglobulin as induction therapy and similar maintenance immunosuppression including tacrolimus, mycophenolate, and prednisolone with the difference in the time of initiation of tacrolimus either on the day of transplantation (immediate tacrolimus group) or day 3 after transplant (delayed tacrolimus group). Findings: DGF incidence (46.15% vs. 37.04%; P = 0.501) and duration (9.75 ± 6.41 vs. 8.6 ± 6.16 days; P = 0.675) were not different between the immediate and delayed tacrolimus groups. Estimated creatinine clearance using Cockcroft–Gault equation (63.14 ± 18.81 vs. 58.19 ± 19.42 mL/min in immediate and delayed tacrolimus groups respectively; P = 0.373) and estimated acute rejection-free survival were also comparable between the groups over the 3 months of follow-up. Compared with the immediate group, the delayed tacrolimus group showed higher estimated 3-month grafts' survival (100% vs. 84.27%; P = 0.072). Conclusion: Delayed initiation of tacrolimus after kidney transplantation under the umbrella of thymoglobulin induction did not result in either lower incidence or duration of DGF or improved the level of graft function in kidney transplant recipients but non-statistically significant increased 3-month grafts' survival.

Diabetic neuropathy (DN) is the most common complication of diabetes mellitus (DM) and also the major cause of morbidity and mortality in diabetic patients. There have been recent speculations that circulating 25-hydroxyvitamin D (25(OH)-D) could be involved in DN development and progression. This study explored the association between serum 25(OH)-D and DN in diabetic subjects by performing strict matching of possible confounders. Overall, 33 diabetic subjects with DN and 29 controls matched in terms of age, sex, BMI, height and disease duration entered this study. Nerve conduction velocity (NCV) was performed to determine the existence and severity of large fiber neuropathy. 25(OH)-D had significantly lower value in DN group (21.2 ± 11.5 vs. 13.5 ± 5.1 ng/mL, P = 0.001). None of the other observed variables showed a significant association with existence and severity of DN. After adjustment for all studied variables, serum vitamin D had an independent and inverse association with both DN presence and severity, as each 1 ng/mL increase in serum 25(OH)-D was correlated with 2.2 and 3.4 % decrease in the presence and severity of NCV impairment, respectively. While adjusted for demographic variables, comorbidities and treatment of DM, our results imply that decreased levels of circulating 25(OH)-D may contribute to increased risk of large fiber neuropathy in type 2 diabetic subjects.
