Assessment of Carotid Intima Media Thickness and Left Ventricular Mass Index in Children with Idiopathic Nephrotic Syndrome.

BACKGROUND: Children with nephrotic syndrome (NS) are at a greater risk of atherosclerosis due to recurrent exposures to hyperlipidemia, hypertension, and immunosuppressive medications. CIMT (carotid intima media thickness) is a reliable marker for assessment of atherosclerosis of large and medium-sized blood vessels; endothelial dysfunction and increased CIMT usually precede the development of cardiovascular diseases. Some manifestations of NS, like proteinuria and hyperlipidemia, are associated with an increased risk of cardiac morbidity and mortality. The aim of the current study was to evaluate the carotid intima media thickness and LVM (left ventricular mass) thickness in children with nephrotic syndrome. SUBJECTS AND METHODS: Eighty-one children with nephrotic syndrome and 100 healthy children as controls were enrolled in the study. The inclusion criteria were: disease duration of minimum of 12 months, glomerular filtration rate >60mL/min/1.73m 2 and children aged two years or more at the time of study. CIMT and left ventricular mass index, lipid profile, protein/creatinine ratio in urine and kidney function tests were done for cases and controls after approval of internal ethical committee. RESULTS: The mean CIMT (mm) was significantly higher in NS (0.51± 0.12) compared to controls (0.42± 0.09) (P <0.001). LVM and LVM Index were significantly higher in NS than controls (p< 0.001, for both). Subsequently, CIMT was significantly correlated to duration of the disease (p< 0.001), LVM index was significantly correlated with duration of the disease, body mass index (BMI), blood pressures and triglycerides level (p< 0.05). CONCLUSION: Children with NS are at increasing risk to develop atherosclerosis as measured by CIMT. LVM was significantly higher in NS and positively correlated to BP, disease duration, triglyceride levels and BMI.

Anemia is a novel predictor for clinical ISR following PCI.

BACKGROUND: Conflicting data were found regarding the anemia's effect on percutaneous coronary intervention (PCI) outcomes. We directed our study to investigate anemia's effect on clinical in-stent restenosis (ISR) following PCI. RESULTS: A prospective multi-center cohort study was performed on 470 consecutive participants undergoing elective PCI. We classified the participants into two groups: group 1 who were anemic and group 2 who were non-anemic as a control group. At 1, 3, 6, and 12 months by clinic visits, we followed up with the patients to assess anemia's clinical ISR effect. We found that 20% of the patients undergoing PCI had anemia. Anemic patients showed a statistically significant higher rate of impaired renal function and diabetes and a higher percentage of the female gender. Multivariate regression analysis for major adverse cardiovascular events (MACEs) after adjusting for confounding factors revealed that anemia represents a more risk on MACE (adjusted hazard ratio (HR) was 4.13; 95% CI 2.35-7.94; p value < 0.001) and carries a higher risk upon clinical ISR (adjusted HR was 3.51; 95% CI 1.88-7.16; p value < 0.001) over 12 months of follow-up. CONCLUSION: Anemic patients going through PCI are generally females, diabetics, and have renal impairment. Anemia might be considered another indicator for clinical ISR and is fundamentally associated with an increased MACE incidence.

Assessment of Cardiovascular Risk Factors in Patients with Type 2 Diabetes in Upper Egypt Villages.

BACKGROUND: A large percentage of diabetic patients also have other components of metabolic syndrome, which is a group of cardiovascular (CV) hazard factors related to both diabetes mellitus (DM) and cardiovascular diseases (CVD). We do not know about the prevalence of CV risk factors in diabetic patients in Upper Egypt. We aimed to assess the CV risk factors in type 2 diabetic patients in Upper Egypt villages. METHODS: We conducted a cross-sectional study that included 800 patients with type 2 DM. We classified the participants into three groups according to the hemoglobin A1c (HbA1c) levels. We assessed the prevalence of other cardiovascular risk factors and their association with HbA1c levels through a detailed history, full clinical examination, and laboratory tests. RESULTS: We found that 75% of the participants were males, 25.5% elderly, 60.25% had hypertension, 60.75% had dyslipidemia, 33.25% were overweight or obese, 19.75% had a family history of coronary artery disease (CAD), 55.75% had established CVD, 42.5% were smokers, and only 12.25% were physically inactive. We found that 84% of the participants had ≥ two cardiovascular risk factors other than DM. HbA1c level was ≥ 7% in 77% of patients. After multivariate regression analysis, we found a significant association of higher systolic blood pressure (BP), more elevated diastolic BP, higher body mass index (BMI), increased waist circumference, old age, long duration of DM, and an increase in the number of clustered CV risk factors with a higher HbA1c level. At the same time, insulin therapy was significantly associated with a lower HbA1c level. CONCLUSION: All type 2 diabetic patients in Upper Egypt villages have other associated CV risk factors. The clustering of cardiovascular risk factors showed a significant association with higher HbA1c levels. These findings require the thought of associated CV risk factors in choosing medical treatments to optimize glycemic control and multifactorial intervention to improve CV risk.

Patient adherence to antihypertensive medications in upper Egypt: a cross-sectional study.

BACKGROUND: Control of hypertension is a very difficult issue. Non-adherence to medications is a well-recognized factor contributing to uncontrolled hypertension. It is required to detect factors that affect adherence of patients to antihypertensive medications at different societies and good planning with the collaboration of governments, universities, media, pharmaceutical companies, and civil society to create intervention programs ensuring good adherence to medications. In our study, we aimed to determine different factors affecting adherence to antihypertensive medications in Upper Egypt societies. RESULTS: From September 2015 to September 2019, we conducted a large cross-sectional multi-center study among 2420 hypertensive patients attending the out-patient cardiac clinics at three different university hospitals. Data was collected through a personal interview with the patients using a questionnaire to cover a variety of items. In the total of 2420 patients, we found that 1116 (46.12%) patients were adherent to medications and 1304 (53.88%) were non-adherent. From the final regression analysis of the results, we found that age > 65 years, illiterate patients, low income, associated comorbidities, using three or more antihypertensive pills, and living in rural areas were statistically significant socio-demographic factors associated with non-adherence to treatment. Also, missing doses of medication and lack of complying with dietary regimen were statistically significant behavioral causes associated with non-adherence. CONCLUSION: Many factors are predictors of good adherence to antihypertensive drugs, including young age, urban residence, a smaller number of pills, absence of comorbid conditions, high income, and high education level. Also missed doses of drugs and absence of complies with dietary regimen were the significant causes of non-adherence. Health institutions and governmental efforts should be directed toward improving adherence by creating effective intervention programs targeting these factors. Therefore, it might be concluded that patients who are more health ware are more adherent to medications than non-health aware patients.

Mean platelet volume as a predictor of pulmonary hypertension in patients with stable COPD.

Background: Pulmonary hypertension (PH) is one of the most common complications developed during the course of chronic obstructive pulmonary disease (COPD). Platelet activation plays an important role in its pathophysiology, and mean platelet volume (MPV) is considered a respectable index of platelet activation. The aim of this work is to assess the ability of MPV in predicting PH secondary to COPD as well as its severity. Methods: A cross-sectional study was conducted on 228 stable COPD patients. CBC, echocardiography, and pulmonary function tests were performed. Results: The prevalence of PH in stable COPD patients was high (63%), and the majority of patients had a mild degree (33%). There was no significant association between PH presence with different COPD grade, but, in very severe COPD, severe PH was significantly presented. MPV in COPD patients with PH was significantly higher than those without (9.02±1.14 vs 7.11±0.98, P<0.001). Moreover, a significant statistical rising of MPV with increased severity of PH. Multivariate regression analysis of predictors of PH demonstrated that; MPV is a real predictor of PH in such patients. The likelihood probability of PH increased up to 7-times with increasing one unit of MPV; (OR=6.7). A cut-off value of MPV >7.25 had 96% sensitivity and 76% specificity in predicting PH. Conclusion: MPV was higher in COPD patients with PH and positively correlated with PH severity. If the data are to be confirmed, MPV may be taken into consideration in decision-making and management of COPD patients.
