Objective: Health-related quality of life (HRQOL) in hypertensive patients may be influenced by the presence and the knowledge of disease, beliefs associated with the disease, blood pressure (BP) control, and drug utilization. The impact of hypertension on HRQOL in hypertensive patients compared to the normal population has not been assessed in Nigeria, the most populous country in sub-Saharan Africa. This study compares HRQOL in hypertensive patients and the normal population; the effect of BP control and medication on HRQOL of hypertensive patients is also assessed. Materials and methods: A prospective cross-sectional study of 713 individuals, 606 were hypertensive patients attending the University College Hospital in Oyo State, Nigeria, while 107 were normal persons residing in Ibadan. Data on sociodemographic status, clinical variables, and drug utilization were collected. World health organization-quality of life short version (WHO-QOL-BREF) questionnaires were used to assess HRQOL of participants. Results: Hypertensive patients had poorer HRQOL compared with normal individuals in the physical health (p < 0.05), psychological (p < 0.01), and total quality of life domains. Blood pressure control had no effect on HRQOL in domain (p > 0.05). Drug use significantly worsened HRQOL of hypertensive patients in the psychological (p ˂ 0.01), social relationship (p < 0.01), and the total quality of life domains (p < 0.01). Multiple regression analysis showed that while income per month was positively predictive of physical, psychological, and total quality of life domains (r2 = 1.988, p=0.001; r2 = 3.710, p < 0.001; r2 = 2.748, p < 0.001), symptom count was negatively predictive of the same (r2 = –0.746, p = 0.005; r2 = 1.869, p < 0.001; and r2 = –1.094; p < 0.001), respectively. Reduced symptoms and higher income improved quality of life in hypertensive patients. Conclusion: The presence of hypertension and antihypertensive medication reduced HRQOL of hypertensive patients, although BP control surprisingly did not impact HRQOL. However, lower symptom count and higher income improved quality of life.

A methanol extract of the seeds of Adenanthera pavonina was evaluated for pharmacological effects in animal models. The extract (50-200 mg/kg) produced statistically significant (P < 0.05) inhibition of the carrageenan-induced paw oedema in the rat, as well as the acetic-acid-induced vascular permeability in mice. At doses of 100 and 200 mg/kg, pleurisy induced with carrageenan was also inhibited. The extract (50-200 mg/kg) exhibited a dose-dependent and significant (P < 0.05) analgesic activity in the acetic-induced writhing in mice. In addition, both early and late phases of the formalin-induced paw licking in mice was inhibited by the extract. Acute toxicity studies revealed that the extract produced reduced motor activity. The LD50 value of the extract was found to be 1.36 g/kg. This study demonstrated the anti-inflammatory and analgesic effects of A. pavonina extract.

Prospective cohort study on 1280 adult patients admitted to the medical wards of a tertiary institution over 12 months. Patients were assessed for ADRs during and throughout admission; causality and preventability of ADRs were assessed. Results: Sixty-seven (5.2%) patients had ADRs, 51 (3.9%) caused hospitalisation while 17(1.3%) occurred during hospitalisation, and 42 (62.7%) of total ADRs were preventable. Nonsteroidal anti-inflammatory drugs, 14 (20.3%), antidiabetics, 12 (17.4%) and antibacterial, 11 (15.8%) were the most implicated drug classes. Gastrointestinal tract (37%), central nervous system (30.2%), and skin (24.7%) were the most affected organ/systems, while upper gastrointestinal bleeding and hypoglycaemia were the most observed ADRs. ADRs led to deaths in 7 (10.4%) patients, with an overall case fatality rate of 0.5%. The highest number of deaths were among patients with Stevens-Johnson syndrome 2/7 (28.6%) and hepatotoxicity 2/7 (28.6%). Risk factors, adjusted odds ratio (AOR [95% confidence interval, CI]) for ADRs leading to hospitalisation was male sex 3.11 (1.11, 8.73) while for ADRs during hospitalisation were number of drugs used before admission (AOR [95% CI] = 6.67 [1.16, 38.47]) and comorbidities (AOR [95% CI] = 3.0 [1.13, 8.01]). Patients admitted with ADRs had prolonged hospital stay (AOR [95% CI] = 3.37 [1.11, 8.71]). Conclusion: Preventable ADRs are common and important causes of hospitalisation and inpatients' morbidity and mortality among medical patients in Nigeria. Upper gastrointestinal bleeding and hypoglycaemia, resulting from nonsteroidal antiinflammatory drugs and antidiabetic drugs were the most observed ADRs.
