Objective Hypertensive crisis is an increasingly frequent medical condition in our context. Its management in medical emergencies is a real challenge for physicians. Few data on hypertensive crisis are available in Chad. The aim of this study was to investigate the epidemiological, clinical and prognostic characteristics of hypertensive crisis in the medical emergency department of Reference National Teaching Hospital in N'Djamena. Patient and methods This was a prospective cohort study running from 1er March 2020 to October 31 2020. Patients presenting with a sudden and severe rise in blood pressure (systolic ≥ 180 mmHg and/or diastolic ≥ 110 mmHg) with or without acute target-organs damage, had been consecutively included and followed up over a period of one (01) month. Epidemic and clinical characteristics on admission, and morbidity and mortality parameters during the course of the disease were collected. The Kaplan-Meier method and the Cox model were used to analyze survival and factors associated with death, with a significance level of p<0.05. Results Of the 3978 hypertensive patients admitted to medical emergencies, 252 had a hypertensive crisis, i.e. a prevalence of 6.3%. Two hundred and seventeen (217) patients were included in the study, divided into 149 cases (69%) of hypertensive emergency and 67 cases (31%) of hypertensive hypertensive urgencies. The mean age of the patients was 55.2 ± 14 years (20 and 80 years) and 67% were male. Hypertension was known in 138 patients (64%). At least one complication was present on admission in 69% of patients. Complications were classified as cardiac (50.7%), neurological (38.2%), kidney impairment (46.5%) and ocular (46.1%). The average number of antihypertensive drugs used was 2 ± 0.83 14. Calcium antagonists (86.5%), diuretics (35.5%), converting enzyme inhibitors or angiotensin II receptor antagonists (33.3%) and betablockers (18%) were the pharmacological classes prescribed. Good compliance during follow-up was observed in 124 patients. One-month survival was 84% for all patients, with a 16% mortality rate. Factors associated with death were the duration of hypertension, and the occurrence of cardiovascular, renal dysfunction and ocular disease (p < 0.05). Conclusion Hypertensive crisis is a frequent pathology in sub-Saharan Africa, with high morbidity and mortality. Prevention requires early detection and effective management of hypertension.

Background Hypertension in adolescents has been shown to tracks into adulthood, as well as causing premature cardiovascular and renal diseases. Objectives To determine the prevalence of elevated blood pressure and hypertension among adolescents of ages 10-19 years old attending secondary schools in Benue South, Nigeria; characterise their demographics and determine factors associated with the development of high blood pressure. Materials and Methods A cross-sectional descriptive study of secondary school adolescents selected through multistage sampling from across three Local Government Areas of Benue South, Nigeria. All the participants had their blood pressure measured using mercury sphygmomanometer and their height and weight taken for the calculation of their body mass index. A dipstick urinalysis with was carried out on their urine samples. Data analysis was with SPSS version 25. Results Atotal of 260 adolescents were studied, males were 132 (50.8%) and the mean age was 13.65 ±2.01 years. The prevalence of elevated blood pressure and hypertension was 5.4% and 2.3% respectively. Fifteen females (75.0%) had elevated blood pressure/hypertension as against five males (25%) and it was statistically significant. Adolescents in mid-adolescence age (60.0%) and lower social class (70.0%) had higher rate of high blood pressure. Significant proteinuria (+) was found among eleven (55.0%) of those with high blood pressure. Conclusion The prevalence of elevated blood pressure and hypertension among the adolescents was 5.4% and 2.3% respectively; being female, within mid-adolescence age and from lower social class are associated factors. Recommendation Regular blood pressure measurement should be part of school health programme. Show less
