The Association of M235T Genetic Polymorphism in Angiotensinogen Gene and Other Non-Genetic Factors with Essential Hypertension among Jordanian Patients.

BACKGROUND: Hypertension, characterized by elevated pressure, poses a significant health risk. Recent studies in Jordan highlight high hypertension rates, emphasizing the need for genetic investigations to comprehend essential hypertension determinants. The AGT gene, part of the Renin Angiotensin System, is linked to blood pressure regulation. Limited information exists on the frequency of this polymorphism among Jordanian hypertensive patients. AIMS: This study explores the association between the AGT M235T polymorphism and essential hypertension in Jordan. METHODS: A cross-sectional study with 435 participants (199 hypertensive, 236 non-hypertensive) was conducted at the University of Jordan Hospital. Blood pressure was measured, and genetic analysis of the AGT M235T polymorphism was completed using the PCR-RFLP technique. Chi-square and t-tests were used for comparisons using SPSS software. RESULTS: Hypertensive patients exhibited significantly higher weight, BMI, and blood pressure. Genotyping results showed no significant difference (p > 0.05, Chi-square) in AGT M235T polymorphism distribution between control and patient groups. In addition, allele frequencies showed comparable patterns (p > 0.05, Chi-square). All genotype frequencies showed no deviation from the Hardy-Weinberg equation (p > 0.05, Chi-square). CONCLUSIONS: The AGT M235T genetic polymorphism is not more prevalent among hypertensive patients in Jordan, although the average weight and BMI among hypertensive patients is higher than the non-hypertensive participants. Obesity can be addressed as a potential risk factor for essential hypertension in Jordan. In addition, it is recommended to find out the influence of the AGT M235T genetic polymorphism on the response of antihypertensive drugs among hypertensive patients in Jordan.

Blood pressure difference between pre and post-menopausal women and age-matched men: A cross-sectional study at a tertiary center.

Hypertension is a prominent risk factor for cardiovascular and cerebrovascular diseases. Gender differences and menopausal status contribute to blood pressure changes across the lifespan which have not been completely characterized. Our study aims to explore the impact of multiple factors on blood pressure levels in previously healthy women and men. Factors of interest included gender, menopausal status, age, and body mass index. Healthy women and men were recruited through healthcare facility announcements. Detailed menopausal history was obtained from females. The authors measured each participant's systolic and diastolic blood pressure at our outpatient clinics twice on the same day, and two different days, one week apart, and the authors included the mean of the averaged two readings for each participant. The study sample consisted of 313 participants. Female gender was a significant predictor of lower systolic and diastolic blood pressure (p < .001), while age significantly correlated with higher systolic blood pressure readings (p = .004). Although systolic blood pressure levels were significantly higher in postmenopausal females (124 mmHg) compared to premenopausal females (116 mmHg), our multiple linear regression analysis revealed that postmenopausal status did not significantly predict changes in either systolic or diastolic blood pressure. Our study demonstrates significant associations between blood pressure levels and various factors such as gender and age. This could emphasize the intricate interplay of demographic and clinical factors in blood pressure variations among individuals, highlighting the importance of a holistic approach to diagnosing hypertension, which considers various individual factors, including gender and age.

Comparison of Baseline and Test Day Cardiovascular Parameters, Anxiety Scores and Coffee Consumption Among Medical Students Undergoing Objective Structured Clinical Examinations in Jordan.

Introduction: Objective Structured Clinical Examinations (OSCEs) are considered an integral part of the assessment process of many schools of medicine worldwide. Close monitoring by examiners, scrutinized interactions with patients, and fear of the unknown, among other factors have been reported to cause psychological stress among students during the examinations period. In this study, we aimed to assess changes in cardiovascular parameters, anxiety scores, and lifestyle patterns of medical students during their OSCEs as compared to their baseline. Materials and Methods: We recruited healthy medical students from our institution's medical school. General demographics, academic, and baseline lifestyle characteristics were collected 1-2 months before the OSCE day. The Generalized Anxiety Disorder 7-item (GAD-7) scale was used to measure anxiety symptoms. Data related to coffee consumption in addition to systolic, diastolic blood pressure and heart rate measurements were collected both at baseline and on OSCE day. Results: This study included 325 students (144 (44.3%) males and 181 (55.7%) females). The mean systolic blood pressure, diastolic blood pressure, and heart rate measurements were significantly higher on OSCE day as compared to the baseline. In addition, the daily consumption of coffee increased significantly during OSCE day as compared to the baseline. Although the anxiety score increased during OSCE day compared to the baseline, the difference was not statistically significant. However, the change in anxiety score (OSCE day - baseline) was significantly higher in females compared to males. Conclusion: In our study, we observed significant increases in blood pressure, heart rate, and coffee intake on the day of the test compared to baseline measurements. These findings underscore the significance of implementing measures to reduce the harmful effects of stress on students during exam preparations and medical school assessments.

Level of Depression and Anxiety on Quality of Life Among Patients Undergoing Hemodialysis.

Background: Despite the growing concern worldwide regarding the quality of life (QoL) and mental well-being among chronic kidney disease (CKD), a few research has been done to address this issue. The study aims to measure depression, anxiety, and QoL prevalence among Jordanian patients with End Stage Renal Disease (ESRD) on hemodialysis and how all of these variables are correlated. Methods: This is a cross-sectional, interview-based study on patients at the Jordan University Hospital (JUH) dialysis unit. Sociodemographic factors were collected, and the prevalence of depression, anxiety disorder, and QOL was assessed using the Patient Health Questionnaire 9 (PHQ9), the Generalized Anxiety Disorder 7-item (GAD7), and the WHOQOL-BREF, respectively. Results: In a study of 66 patients, 92.4% had depression, and 83.3% had generalised anxiety disorder. Females had significantly higher depression scores than males (mean = 6.2 ± 3.77 vs 2.9 ± 2.8, p < 0.001), and single patients had significantly higher anxiety scores than married patients (mean = 6.1 ± 6 vs 2.9 ± 3.5, p = 0.03). Age was positively correlated with depression scores (rs= 0.269, p = 0.03), and QOL domains showed an indirect correlation with GAD7 and PHQ9 scores. Males had higher physical functioning scores than females (mean = 64.82 vs 58.87, p = 0.016), and patients who studied in universities had higher physical functioning scores than those with only school education (mean of College/University = 78.81 vs mean of School Education = 66.46, p = 0.046). Patients taking <5 medications had higher scores in the environmental domain (p = 0.025). Conclusion: The high prevalence of depression, GAD, and low QOL in ESRD patients on dialysis highlights the need for caregivers to provide psychological support and counselling for these patients and their families. This can promote psychological health and prevent the onset of psychological disorders.

Hypertension and depression among medical students: is there an association?

Introduction: Several studies suggested a higher prevalence of hypertension and depression among medical students. Patients with depression have a higher prevalence of hypertension and vice versa. In this study, we assessed the frequency of hypertension and depression in a sample of medical students and the impact of depression on hypertension. Methods: We recruited medical students from the largest medical school in Jordan. For each participant, we measured blood pressure and heart rate under standardized measurement conditions. Participants were also surveyed using the 9-item Patient Health Questionnaire (PHQ-9). We performed univariate analysis followed by linear regression analysis of factors affecting mean arterial pressure. Results: 354 medical students were included. The mean age was 21 years. 196 (55.4%) were females and 158 (44.6%) were males. 139 (70.9%) of females had normal blood pressure (BP), 7 (3.6%) had elevated BP, 44 (22.4%) had stage 1 hypertension (HTN), and 6 (3.1%) had stage 2 HTN. Within males: 60 (38.0%) had normal BP, 27 (17.1%) had elevated BP, 55 (34.8%) had stage 1 HTN, and 16 (10.1%) had stage 2 HTN. 114 participants (32.2%) had no or minimal depression, 197 (55.6%) had mild-moderate depression and 43 (12.1%) had moderately severe-severe depression. There was an association between higher depression scores and higher diastolic blood pressure. Conclusion: The frequency of hypertension and depression was notably high in our sample. There was an association between higher depression scores and higher diastolic blood pressure. We strongly believe that this association should encourage us again to screen our hypertensive patients in general for depression and vice versa. We also recommend adopting screening programs for depression and hypertension in general.

Acute Kidney Injury Among Patients with Multi-Drug Resistant Infection: A Study from Jordan.

Background: Acute kidney injury (AKI) is a well-known complication for hospitalized patients. Sepsis and various infections play a significant role in increasing the incidence of AKI. The present study evaluated the risk for Multidrug-resistant (MDR) infections and its effect on the incidence of AKI, hospitalization, need for dialysis, and mortality. Methods: In a retrospective study design, data were collected from all adult patients with a positive multi-drug resistant culture who were admitted to King Abdullah University Hospital (KAUH). Records of 436 patients were reviewed between January 2017 - December 2018 with at least one year of follow-up. Results: The mean age was 57.3 years (SD± 23.1), and 58.5% were males. The most common source of positive cultures was sputum, with 50% positive cultures. The incidence of AKI was 59.2%. The most isolated microorganism was Acinetobacter baumannii (76.8%), followed by Pseudomonas aeruginosa (14.9%).On multivariate analysis, age (OR 1.1, 95% CI 1.1-1.2, P=0.001), HTN (OR 1.8, 95% CI 1.0-3.3, P=0.02), DM (OR 1.1, 95% CI 0.6-1.9, P=0.69) and the use of Foley catheter on chronic bases (OR 4.3, 95% CI 2.6-6.8, P<0.0001) were strong predictors of AKI. Among patients with AKI, 74.4% died compared to 44.4% among non-AKI patients (p<0.001). Conclusion: In patients with MDR, AKI incidence, hospitalization, and mortality were high. Early detection and addressing the problem may decrease bad outcomes, and health education for reducing antibiotic abuse is needed to lower MDR.

Prevalence of Undiagnosed Hypertension and Its Predictors in Jordan: A Cross-Sectional Study.

Introduction: Hypertension is an important cause of morbidity and mortality worldwide. Undiagnosed hypertension is a serious issue that leads to increased morbidity and mortality. In this study, we aim to identify the prevalence of undiagnosed hypertension in the healthy Jordanian population, as well as identify predictors of high blood pressure readings in presumably healthy Jordanians. Materials and Methods: We recruited healthy visitors accompanying patients at our Jordan University Hospital Clinics ranging from 18 to 80 years of age. We measured each participant's systolic and diastolic blood pressure at our outpatient clinics on two different days, one week apart. We also obtained demographic data, weight, height, smoking status, and family history of hypertension and cardiovascular diseases. Results: A total of 896 participants were included in this study with a mean age of 48 years. The median of systolic blood pressure readings was 125 mmHg, and the median of diastolic blood pressure readings was 83 mmHg. 38.5% had undiagnosed stage 1 hypertension and 30.5% had undiagnosed stage 2 hypertension according to the American College of Cardiology/American Heart Association guidelines. On the other hand, 25.4% had undiagnosed grade 1 hypertension and 5.1% had undiagnosed grade 2 hypertension according to the European Society of Hypertension guidelines. Conclusion: According to the ACC/AHA guidelines, 68.5% of previously healthy Jordanians met the criteria to be diagnosed with hypertension. Predictors of high systolic blood pressure were age, BMI and family history of CAD, while female gender is associated with a lower systolic blood pressure. For diastolic blood pressure, only BMI and family history of CAD were associated with significantly higher diastolic blood pressure, while female gender and exercise were significantly associated with lower diastolic blood pressure.

Prevelance of depression and anxiety with their effect on quality of life in chronic kidney disease patients.

Chronic kidney disease is one of the most common chronic diseases globally. Many studies have shown it is strongly associated with increased social and psychological problems such as depression and anxiety which are considered as common psychiatric disorders that occur in patients with chronic kidney disease. We investigated the prevalence of depression, anxiety and perception of quality of life in a sample of chronic kidney disease patients at the Jordan University Hospital. We aimed to see any association of the mental health in these patients; mainly depression and anxiety with their quality of life and correlation to socio-demographics or laboratory and metabolic profile of this population. 103 chronic kidney disease patients were interviewed using a questionnaire in the Nephrology outpatient clinics of the Jordan University Hospital, the questionnaire included four sections, the first sections handled socio-demographic data. Also, it contains a brief Clinical and laboratory parameter of our patients. The second part consisted of the 9-item Patient Health Questionnaire (PHQ-9) that used to measure the severity of depression. The third part included the 7-item Generalized Anxiety Disorder (GAD-7) to evaluate the severity of anxiety, the fourth part assessed participants quality of life (QOL) using The World Health Organization Quality of Life, Short Form (WHOQOL-BREF) questionnaire. More than half of the participants have depression and anxiety with a percentage of 58.3% and 50.5%, respectively. There was a negative moderate to strong correlation between depression score and quality of life domains scores (p < 0.001).Only marital status had a significant relationship with depression (p < 0.001).Weak positive correlation between Glomerular Filtration Rate and anxiety score (p = 0.04),with significant positive correlation between lipid profile and anxiety score. There was a negative correlation between anxiety score and quality of life domains scores. Females had higher anxiety score than males (p = 0.27). Patients who do not work had a lower physical functioning score compared to others (p value = 0.024).Patients with higher serum Hemoglobin had higher physical and psychological scores. Anxiety, Depression are common among our chronic kidney disease patients, more interventions are needed to improve the mental health of our patients and their quality of life perception. This kind of study allows us to gain a deeper understanding regarding the effects of chronic kidney disease on psychosocial well-being of those patients, and helps health care providers to put depression, anxiety and Quality of life into consideration when treating patients.

Acute Kidney Injury among Hospital-Admitted COVID-19 Patients: A Study from Jordan.

Objective: During the COVID-19 pandemic, many patients have been admitted to hospitals with severe respiratory disease and suffered complications. Acute kidney injury (AKI) is among the more dangerous complications contributing to morbidity and mortality among patients. Methods: This retrospective study focused on all hospital-admitted COVID-19 patients between September and December 2020. A total of 1,044 patients were enrolled. Patient demographics, medical records, and laboratory data were gathered. Patients were split into two groups: AKI and non-AKI. Comparisons comprised demographics, labs, ICU transfer, need for ventilation and oxygen therapy, medications, hospital stay, and deaths. Results: AKI incidence in the cohort was 25.3%, and a majority were stage 1 (53.3%). Among these, hemodialysis was started in 1.8%. Higher age (P<0.001), diabetes mellitus (P=0.001), hypertension (P=0.001), ACEI/ARB use (P=0.008), erythrocyte-sedimentation rate (P=0.002), CRP (P<0.0001), and ferritin (P=0.01) were predictors of AKI. Among all admitted COVID-19 patients, 30.2% died in hospital. Among those with AKI, 75.9% died in comparison to 24.1% of non-AKI patients (P<0.001). Among COVID-19 patients admitted to the ICU, 80.5% died: 70.5% were from the AKI group and 29.5% from the non-AKI group (P<0.001). Conclusion: High mortality and morbidity is associated with COVID-19 infection, and AKI is contributing significantly to the outcomes of hospitalized patients with the infection. Early recognition of and treatment for AKI will decrease mortality and hospitalization in patients with COVID-19.

Elevated interleukin 31 serum levels in hemodialysis patients are associated with uremic pruritus.

INTRODUCTION: Uremic pruritus is a multifactorial devastating complication of renal failure, which has a significant negative impact on patients' quality of life including medical, psychological, as well as social aspects. It is also associated with an increased mortality in dialysis patients. METHODS: A cross sectional study evaluating the traditional risk factors for uremic pruritus (UP) - using pruritus grading system (PGS) and visual analogue scale (VAS) - as well as measuring the serum levels of different inflammatory cytokines (ILs 13, 31 and 33) in chronic hemodialysis and healthy controls, in a tertiary referral hospital. RESULTS: 65 hemodialysis (HD) patients and 49 heathy controls were enrolled in the study. The mean age for the HD patients was 43.4 years (SD ± 21.3), and 31.5 years (SD ± 11.1) for the control group. The most common cause for End Stage Renal Disease (ESRD) was diabetes mellitus (DM) 27.7%. The mean PGS score in HD patients was 5.92 (SD ± 2.9); 50% had mild itch, 43.8% moderate itch and 6.2% had severe itch. The mean serum levels for IL-13 was 8674.3 pg/ml (SD ± 4353.9), serum levels of IL-31 were 150.7 pg/ml (SD ± 178.2) and for IL-33 it was 42850.5 pg/ml (SD ± 11370.7) in hemodialysis patients; in comparison to serum levels of 7913.4 pg/ml (SD ± 3454.1), 67.1 pg/ml (SD ± 71.9) and 44875.9 pg/ml (SD ± 12114.6), respectively in the control group. IL-31 level was significantly higher in HD patients than in the control group (P = 0.0001), while the difference in the levels of IL-13 and IL-33 between the two groups were not statistically significant (P = 0.41 and 0.18, respectively). IL-13 had a statistically significant relationship with the itch score (P = 0.014) and the severity of itch (P = 0.03), while IL-31 and IL-33 were not statistically significant. CONCLUSION: UP is a complex and multifactorial problem. In patients with UP the high levels of IL-31 indicates a possible role in pathogenesis. IL-13 serum level on the other hand may be related to the severity of itch in these patients. Optimizing dialysis and targeting these cytokines may provide a potential therapeutic option especially in refractory UP. Further studies addressing these cytokines and their levels in response to various treatments may provide additional information on UP.

Renal dysfunction among rheumatoid arthritis patients: A retrospective cohort study.

BACKGROUND: Rheumatoid arthritis (RA) is a common rheumatological disease which can involve a variety of different renal manifestations. This may be explained by disease effect itself or by medications used for treatment that may lead to renal dysfunction and its complications.We aimed to identify the prevalence and factors that played a role in renal dysfunction among RA Jordanian patients. METHOD: 285 patients with RA visiting outpatient clinic between March 2016 and March 2017 were included in a retrospective study design. Age, gender, comorbidities, duration of the disease, medications and laboratory results were gathered and scoring of RA activity was done. RESULTS: Data gathered from the 285 patients showed a female predominance with 88.4% female and 11.6% male. The average disease duration was 6.7 years. Age, DM, HTN, and serum CRP were associated with worse renal function on univariate analysis. 44 patients (18.8%) presented with microscopic hematuria, 16 (6.9%) with proteinuria and only 5 (2.1%) patients presented with both microscopic hematuria and proteinuria. Patients with eGFR <60 ml/min had longer disease duration with a mean of 11 years (±7.7) in comparison to 6.4 years (±6.1) for those with eGFR>90 ml/min (P = 0.001). CONCLUSION: Renal dysfunction is not common in RA Jordanian population and has variable presentations. Age and the duration of illness play a major role in the progression of CKD if present. Future prospective studies evaluating renal biopsies in RA patients are needed.

Sarcoidosis in Jordan: A Study of the Clinical Phenotype and Disease Outcome.

OBJECTIVES: This study aims to evaluate the clinical phenotypic features of sarcoidosis in a single-center academic hospital in Jordan. PATIENTS AND METHODS: A retrospective file review was performed at an academic medical center in Jordan that included all patients diagnosed with sarcoidosis between January 2000 and December 2018. A total of 150 patients with sarcoidosis (38 males, 112 females; mean age 47.8±11.7 years; range, 17 to 79 years) were evaluated. Clinical data extracted from the files included the sex of the patient, the age at time of diagnosis, diagnosis date, the season during which the diagnosis was established, and smoking history. Biopsy histopathology, spirometry, nerve conduction, echocardiography, and imaging reports including plain radiographs, ultrasonographic, magnetic resonance and computed tomography reports were reviewed. Data including laboratory values, medication usage, clinical outcomes, and morbidity/mortality were collected. Pulmonary function tests including spirometry and lung volumes along with the diffusing capacity for carbon monoxide were reviewed for the presence of restriction, obstruction or reduction in the diffusion capacity of carbon monoxide. Identification of extra-thoracic organ involvement was determined in each patient in accordance with the criteria suggested by the updated World Association of Sarcoidosis and Other Granulomatous Disorders. RESULTS: A total of 77.3% of the patients were diagnosed by biopsy. One case of Lofgren's syndrome was identified. Of the patients, 18.0% had isolated pulmonary sarcoidosis, 75.3% had pulmonary and extra-pulmonary sarcoidosis and 6.7% had isolated extra-pulmonary sarcoidosis while 81.3% had respiratory symptoms, mostly shortness of breath and cough. Extra-thoracic organ involvement mostly involved the musculoskeletal system (33%) followed by the skin (20%). Female patients had more extra-thoracic involvement but the sex difference was only statistically significant for cutaneous involvement. Of the patients, 84% received treatment while 20% had disease remission during the first two years after diagnosis and 70% required treatment beyond two years after diagnosis. CONCLUSION: Various sarcoidosis clinical phenotypes are seen among Jordanian patients. Jordanian females are more affected by the disease and have more extra-thoracic involvement compared to male patients. A large number of the study patients received treatment.

Long-Term Follow-Up of Contrast-Induced Acute Kidney Injury: A Study from a Developing Country.

INTRODUCTION: Contrast-induced acute kidney injury (CI-AKI) is a worldwide known complication related to the use of contrast media with either imaging or angiography; it carries its own complications and effect on both morbidity and mortality; early identification of patients at risk and addressing modifiable risk factors may help reducing risk for this disease and its complications. METHODS: This was a prospective observational study, where all patients admitted for cardiac catheterization between June 2015 and January 2016 were evaluated for CI-AKI. There were two study groups: contrast-induced acute kidney injury (CI-AKI) group, and noncontrast-induced acute kidney injury (non-CI-AKI) group. RESULTS: Patients (n = 202) were included and followed up for 4 years. Death and development of chronic kidney disease (CKD) need for another revascularization were the end points. The incidence of CI-AKI was 14.8%.In univariate analysis, age (P = 0.016) and serum albumin at admission (P = 0.001) were statistically significant predictors of overall death. Age (P = 0.002), HTN (P = 0.002), DM (P = 0.02), and the use of diuretics (P = 0.001) had a statistically significant impact on eGFR. The rate of recatheterization was not statistically significant between the two groups (61 (35.5%) for the non-CI-AKI vs. 12 (40%) for the other group; P = 0.63). Some inflammatory markers (NGAL P = 0.06, IL-19 P = 0.08) and serum albumin at admission P = 0.07 had a trend toward a statistically significant impact on recatheterization. Death (P = 0.66) and need for recatheterization (P = 0.63) were not statistically different between the 2 groups, while the rate of eGFR decline in for the CI-AKI was significant (P = 0.004). CONCLUSION: CI-AKI is a common complication post percutaneous catheterization (PCI), which may increase the risk for CKD, but not death or the need for recatheterization. Preventive measures must be taken early to decrease the morbidity.

Incidence, Risk Factors, and Outcome of Acute Kidney Injury in the Intensive Care Unit: A Single-Center Study from Jordan.

BACKGROUND: Acute kidney injury (AKI) is a common serious problem affecting critically ill patients in intensive care unit (ICU). It increases their morbidity, mortality, length of ICU stay, and long-term risk of chronic kidney disease (CKD). METHODS: A retrospective study was carried out in a tertiary hospital in Jordan. Medical records of patients admitted to the medical ICU between 2013 and 2015 were reviewed. We aimed to identify the incidence, risk factors, and outcomes of AKI. Acute kidney injury network (AKIN) classification was used to define and stage AKI. RESULTS: 2530 patients were admitted to medical ICU, and the incidence of AKI was 31.6%, mainly in stage 1 (59.4%). In multivariate analysis, increasing age (odds ratio (OR) = 1.2 (95% CI 1.1-1.3), P = 0.0001) and higher APACHE II score (OR = 1.5 (95% CI 1.2-1.7), P = 0.001) were predictors of AKI, with 20.4% of patients started on hemodialysis. At the time of discharge, 58% of patients with AKI died compared to 51.3% of patients without AKI (P = 0.05). 88% of patients with AKIN 3 died by the time of discharge compared to patients with AKIN 2 and 1 (75.3% and 61.2% respectively, P = 0.001). CONCLUSION: AKI is common in ICU patients, and it increases mortality and morbidity. Close attention for earlier detection and addressing risk factors for AKI is needed to decrease incidence, complications, and mortality.

Effect of Hydrocortisone on Intradialytic Hypotension: A Preliminary Investigational Study.

INTRODUCTION: Approximately 15 to 33% of all dialysis treatments are complicated by intradialytic hypotension (IDH). In this study, we tested the hypothesis that the intravenous administration of hydrocortisone prior to HD treatment could prevent IDH or at least decrease the drop in the blood pressure resulting from IDH. METHODS: This study was approved by our local ethics committee/IRB (2017/87) and by the Jordan Food and Drug Administration (7/clinical/18). Additionally, it is registered on ClinicalTrials.gov (NCT03465007). In this preliminary investigational study, we screened all chronic hemodialysis patients at our clinic who were 18 years of age or older (n = 82) for IDH. There were 14 patients included in the interventional part of this study; patients were given IV hydrocortisone for 3 consecutive HD sessions, followed or preceded by 3 intervention-free sessions where they were given 5 ml of saline as a placebo. RESULTS: The initial total sample size was 82 patients. The frequency of IDH at our clinic was 24.4%. Fourteen out of the 20 patients who were diagnosed with IDH agreed to enroll in the interventional part of our study. The mean age of the patients in the interventional part of our study was 53.5 years (±10.3). These patients included 5 (35.7%) men and 9 (64.3%) women. Upon comparing the number of hypotensive attacks with and without the hydrocortisone administration, we found a significant difference (p = 0.003) between the hydrocortisone and placebo treatments in which 12 (85.7%) patients had fewer IDH episodes with the hydrocortisone treatment than with placebo. CONCLUSION: This preliminary investigational study found that the administration of a stress dose of hydrocortisone prior to hemodialysis could be an effective measure for preventing or minimizing the risk of IDH episodes. Additional prospective studies on this subject are needed. Ruling out adrenal insufficiency in patients diagnosed with IDH is also crucial.

Prevalence of metabolic syndrome in dialysis and transplant patients.

Background: Several epidemiological studies have assessed various components of Metabolic Syndrome (MS) in different populations, but only a few compared the prevalence of metabolic syndrome in dialysis and transplant patients. Aim: The aim of this study is to compare the prevalence of MS in dialysis and transplant patients. Two groups of patients were included; hemodialysis patients and patients with transplanted kidneys. Methods: Demographic and clinical history, and lab data were collected. A total of 108 patients were included in this study with a mean age of 52.3 (±16.29) years. Study groups included 61 (56.5%) dialysis patients, and 47 (43.5%) patients with transplanted kidneys. Results: Upon comparing the prevalence of metabolic syndrome between the two study groups, transplant patients had significantly lower prevalence of metabolic syndrome (34%) compared to that of metabolic syndrome in patients on dialysis (55.7%; P=0.016). Conclusion: As metabolic syndrome plays an important role in the pathology of elderly patients, especially those with transplanted kidneys, such findings indicate the need for close monitoring of kidney transplant patients for the manifestations of metabolic syndrome.

Acute kidney injury among nonagenarians in Jordan: a retrospective case-control study.

BACKGROUND: Improvements in health care systems worldwide have had notable effects on the life expectancy of older individuals. As a result, nonagenarians are emerging as a separate age group with distinct health care needs. The aim of this study was to evaluate the incidence of acute kidney injury (AKI), the mortality rates, and length of in-hospital stay among nonagenarians. METHODS: This is a retrospective case-control chart review of patients of age 90 years and above who were admitted to hospital. Patients with Stage I, II, or III chronic kidney disease were included in the analysis. The incidence of AKI was determined using data from the Acute Kidney Injury Network (AKIN) classification. Primary outcome variables included length of in-hospital stay and mortality rates. RESULTS: Of the 253 patients who were included in the study, the mean age was 91.5 years, 61 of the patients (25.9%) developed AKI, and 41 patients (66.1%) were in Stage I AKI according to AKIN criteria. Fifty-seven patients died during the study period; 57.9% of those patients had AKI. Hospital stay was longer in patients with AKI with a mean length of stay of 8.1 days. Congestive heart failure, cancer, and use of non-steroidal anti-inflammatory drugs were the main risk factors for AKI among those patients. CONCLUSION: AKI is common in nonagenarians. It was associated with increased length of hospital stays and increased risk for mortality.

Inflammatory milieu in contrast-induced nephropathy: a prospective single-center study.

BACKGROUND: Acute kidney injury (AKI) caused by contrast exposure is a common problem, which may cause a significant increase in patients in-hospital stay and therefore the cost of treatment. This study was conducted to evaluate the role of inflammation, inflammatory markers in predicting contrast induced nephropathy (CIN). This is a prospective study that was carried out in a major tertiary referral hospital in Jordan. METHODS: Clinical data, blood and urine samples were collected from all patients admitted to the cardiology unit. All patients who agreed to participate in the study had creatinine level analysis 48-72 hours after the procedure. The CIN was defined as an increase in serum creatinine by 25% or 44 µmol/L from the baseline within 48-72 hours after the contrast administration. Patients with stage 4, 5 renal failure, patients on dialysis, and patients with recent intravenous contrast use, active infection or cancer were excluded from the study. RESULTS: Of the total 202 patients, 30 (14.8%) developed CIN. The incidence rate was 21.1% among females and 12.4% among males. In the multivariate analysis, beside eGFR, diuretics, and alkaline phosphatase, IL-33 was significantly associated with CIN, while the other cytokines did not to show this an association. CONCLUSION: Serum level of IL-33 was a significant predictor for development of CIN. Good clinical judgment and high serum levels of IL-33 may stratify patients into low and high risk for CIN.

Incidence and outcomes of acute kidney injury in octogenarians in Jordan.

OBJECTIVE: Improvements in the health care system, resulted in a greater number of geriatric patients diagnosed with acute kidney injury (AKI). We evaluated the incidence and outcome of AKI in octogenarians, as studies in the Middle-East region are few; moreover, treatment approaches, in addition to medical decisions, may require special consideration for advanced age to improve the outcomes. RESULTS: At King Abdullah II teaching and referral hospital, we recruited patients aged 80-90 years who were admitted to the medical floor between January 2010 and December 2013. Patients were followed-up for at least 1 year after discharge.850 patients were admitted during the study period. Of these, 135 were excluded from our analysis. The most common admission diagnoses were uncontrolled diabetes mellitus and acute coronary syndrome. AKI occurred in 216 patients (30.2%). Using the acute kidney injury network classification; stage 1, stage 2, and stage 3 disease were present in 59, 17.5, and 23.5% of patients, respectively. Of the 115 patients who died before discharge (16.1%), 87 (75.6%) had developed AKI. Hypertension, the use of angiotensin receptor blockers and non-steroidal anti-inflammatory drugs, heart failure, and exposure to radiologic contrast media were significant risk factors for AKI.

Circumferential stent fracture repaired using a covered stent in a 42-year-old man with coarctation of the aorta.

We present a case of circumferential fracture of aortic coarctation stent with severe re-stentosis presenting 16 years after initial stent implantation with end-stage renal disease. The patient was treated with a covered stent using the stent-in-stent technique. The use of an ultra-high-pressure balloon was proved necessary to overcome the tight, non-compliant stenosis.
