Hypertension is a major modifiable risk factor for cardiovascular disease (CVD) which is a leading cause of death in developing countries affecting both genders. Gender dissimilarity in clinical characteristics and hypertension (HTN) management among hypertensive patients has been reported in several reports before. The aim was to detect sex differences in clinical characteristics and HTN management among Egyptian hypertensive patients. Data from 4701 hypertensive patients attending 9 university located Specialized Hypertension clinic (SHC) were collected from October 2014 to September 2017. The collected data included demographics, cardiovascular risk profile, hypertension-related history, anthropometric and blood pressure (BP) measurements, antihypertensive medications used, number of patients attending the follow-up visits, and HTN control rate. Females represented 58.5% of the recruited patients, they were younger, with higher BMI, lower education level, and employment rate compared with males. Females had lower mean office systolic and diastolic BP than males (144.2 ± 22.6 vs. 146.5 ± 22.0 mmHg and 88.1 ± 13.0 vs. 89.9 ± 12.6 mmHg, respectively) and lower rate of uncontrolled BP (54.8% vs. 61.1% in males P < .001). Antihypertensive drugs were comparable among both sexes except for angiotensin converting enzyme inhibitors which were more prescribed in males. Compliance to antihypertensive medications was better in females (63.6% vs. 60.1% in males, P = .015). To conclude, Egyptian hypertensive females have different clinical characteristics as compared to their counterpart males with better BP control, adherence to antihypertensive medications, lower systolic and diastolic BP, and no major differences in the prescribed antihypertensive distribution.

Once versus twice daily antihypertensive medications for the control of nocturnal blood pressure: a comparative study.

Egypt Heart J 2020 Mar 4;72(1). Epub 2020 Mar 4.

Helwan University, Faculty of Medicine, Cairo, Egypt.

Background: Blood pressure (BP) shows short-term variability within the 24 h, which can only be assessed with 24-h ambulatory blood pressure monitoring (ABPM). It is of utmost importance to control BP throughout the night to reduce incidence of hypertension complications. The purpose of this study is to evaluate the effect of timing and frequency of antihypertensive medications on the average nighttime and 24-h blood pressure control.

Results: The study enrolled 199 hypertensive patients with controlled office blood pressure; 135 (67.8%) patients were on once daily antihypertensive medication (group 1) while 64 (32.2%) patients were on twice daily doses (group 2). The mean office SBP was 128.7 ± 7.8 mmHg in group 1 vs 129.6 ± 6.6 mmHg in group 2, (p = 0.421). ABPM readings for both groups were as follows: mean daytime SBP was 125.4 ± 11.6 mmHg vs 130.1 ± 12.9, p = 0.011; mean nighttime SBP was 117.0 ± 12.4 mmHg vs 123.1 ± 13.9 mmHg, p = 0.002, and mean 24-h SBP was 122.7 ± 10.6 mmHg vs 127.5 ± 12.0, p = 0.005. The prevalence of non-dipping was 68.9% in group 1 vs 70.3% in group 2 patients, p = 0.8 (the mean dipping ratio was 0.93 ± 0.08 in group 1 vs 0.95 ± 0.07 in group 2, p = 0.198). The prevalence of masked hypertension was higher in group 2 (28.1% vs 43.8%, p = 0.029).

Conclusion: Taking an extra antihypertensive pill at night did not show a decrease in the nighttime or the average 24H blood pressure in hypertensive patients with controlled office BP. On the contrary, patients who used twice daily antihypertensive medications seem to have higher nighttime and 24-h SBP, although the dipping ratio was comparable in both groups.

Registry of the Egyptian specialized hypertension clinics: patient risk profiles and geographical differences.

J Hum Hypertens 2020 07 26;34(7):520-527. Epub 2019 Sep 26.

Cardiology Department, Cairo University, Cairo, Egypt.

Data regarding the prevalence and characteristics of cardiovascular (CV) risk factors among Egyptian hypertensive patients are limited. Nationwide Specialized Hypertension Clinics (SHCs) were initiated for screening, investigating, and treating hypertensive patients. This study aimed to determine the clinical characteristics and the CV risk profile of hypertensive Egyptians attending SHCs. Data from 4701 hypertensive patients were collected from the SHCs of nine university hospitals representing the different geographical regions of Egypt. Data collection started in October 2014 and ended in September 2017. Data included blood pressure (BP) measurements, clinical data, socio-demographic characteristics, anthropometric measurements, and cardiovascular risk profiles. The patients' mean age was 51.8 ± 11.5 years, 58.7% were older than 50 years, and 58.5% were females. The mean office systolic and diastolic BP values were 145.2 ± 22.4 and 88.7 ± 12.9 mmHg, respectively. Regarding CV risk factors, 58.6% were obese, 23.4% were smokers, and 25.1% had diabetes mellitus. Obesity was more prevalent in females than males (65.7% vs. 53.0%, p < 0.001, respectively), while dyslipidaemia and smoking were significantly more common in male patients. The highest levels of BP and the highest global risk were observed in the inhabitants of the Delta region, despite their younger age. In conclusion, this study revealed a high prevalence of modifiable CV risk factors among a cohort of Egyptian hypertensive patients attending SHCs. The pattern of the risk factors across the different geographic regions may be attributed to rapid urbanization. Governmental and community-based approaches are needed for better control of hypertension and its associated CV risk factors.

Masked uncontrolled hypertension: Prevalence and predictors.

Egypt Heart J 2018 Dec 22;70(4):369-373. Epub 2018 Oct 22.

Cairo University, Cairo, Egypt.

Background: There are limited data on 'masked uncontrolled hypertension' (MUCH) in patients with treated and apparently well-controlled BP is unknown.

Objectives: To define the prevalence and predictors of MUCH among hypertensive patients with controlled office blood pressure.

Methods: One hundred ninety-nine hypertensive patients presented to the specialized hypertension clinics at two University Hospitals. All patients had controlled office blood pressure (less than 140/90 mmHg). Patients were assessed regarding history, clinical examination, and laboratory data. All patients underwent ambulatory blood pressure monitoring (ABPM) for 24 h, within a week after the index office visit. MUCH was diagnosed if average 24-h ABPM was elevated (systolic BP ≥ 130 mmHg and/or diastolic BP ≥ 80 mmHg) despite controlled clinic BP.

Results: Sixty-six patients (33.2%) had MUCH according to 24-h ABPM criteria (mean age 53.5 ± 9.3 years, 60.6% men). MUCH was mostly caused by the poor control of nocturnal BP; with the percentage of patients in whom MUCH was solely attributable to an elevated nocturnal BP almost double that due to daytime BP elevation (57.3% vs. 27.1%, P < 0.001). The most common predictors of MUCH were smoking, DM and positive family history of DM.

Conclusion: The prevalence of masked suboptimal BP control is high. Office BP monitoring alone is thus inadequate to ascertain optimal BP control because many patients have an elevated nocturnal BP. ABPM is needed to confirm proper BP control, especially in patients with high cardiovascular risk profile. Smoking, DM and positive family history of DM were the most common predictors of MUCH.

Outcome of Living-Donor Liver Transplant for Hepatocellular Carcinoma: 15-Year Single-Center Experience in Egypt.

Exp Clin Transplant 2017 Mar;15(Suppl 2):12-20

Department of Surgery, Ein Shams University, Cairo, Egypt.

Objectives: Liver transplant performed for hepatocellular carcinoma must adhere to criteria for the size and number of focal hepatic lesions to lower the incidence of recurrence and achieve survival rates comparable to patients transplanted for other indications. Since the Milan criteria were established in 1996, there have been many less restrictive criteria yielding similar results. Our aim was to identify the prognostic factors for patient survival and for recurrence of hepatocellular carcinoma for patients within and beyond the Milan criteria.

Materials And Methods: This retrospective and prospective analysis was conducted in 60 adult patients who underwent right lobe living-donor liver transplant for cirrhosis complicated by hepatocellular carcinoma at Dar Al Fouad Hospital, 6th of October City, Egypt, between August 2001 and June 2012. The median follow-up was 39.5 months.

Results: Overall 1-, 3-, and 5-year survival rates were 98.3%, 93.5%, and 71.4%. Overall disease-free survival rates at 1, 3, and 5 years were 96.6%, 93.5%, and 64.2%. There was no statistically significant difference in overall survival time between patients within and beyond the Milan criteria. Factors affecting recurrence were the tumor grade, lobar distribution, size of the largest nodule, and the total tumor burden in the explanted liver. Recurrence adversely affected survival.

Conclusions: Using our criteria of a single tumor ≤ 6 cm, or 2 to 3 tumors with the largest ≤ 4.5 cm, or 4 to 5 tumors with the largest ≤ 3 cm and total tumor size ≤ 8 cm resulted in overall survival comparable to patients within the Milan criteria.
