Challenges of accessing care in art clinic during COVID-19 lockdown in Lagos

Background: As the SARS-CoV-2 pandemic continues to ravage the world, its impact on the health systems and survival of people with chronic diseases especially People living with HIV [PLWH] could be undermined. It becomes relevant to assess the challenges PLWH face during this period to institute measures towards combating the negative effects of the pandemic. Aims: This study aims to investigate the challenges faced by PLWH in accessing care during the lockdown period in Lagos, Nigeria. The study was a cross-sectional one involving PLWH aged 18 years and above who presented for care. An interviewer-administered questionnaire was used to obtain information on demographic characteristics, their knowledge about COVID-19 disease, and challenges experienced in accessing care during the COVID-19-induced lockdown. Ethical approval was obtained from the Institution Research Ethics Board (IRB) of NIMR. Patients and Methods: Data generated from the survey was exported to Excel and analyzed using SPSS version 23.0. Results: The mean age of PLWH who participated in the study was 42.2 (±12.2) years. The majority were female (74.3%), married (66.3%), employed (58.9%), and on less than $100 monthly income (80.5%). The commonest challenges experienced were psychological (78.5%), financial (68%) and food (40.7%). There were significant association among the income status, lack of food (OR: 2.5, CI: 1.4-4.5, P = 0.002), financial challenges (OR: 1.7, CI: 1.0­3.0, P = 0.048) and psychological challenges (OR; 1.8, CI: 1.0-3.5, P = 0.05). Ninety­five percent of participants believed SARS-COV-2 infection is a viral infection. Conclusions: PLWH faces a myriad of challenges that would have a significant impact on their overall well-being and the gains of HIV care.

Blood Pressure Control and Left Ventricular Hypertrophy in Hypertensive Nigerians

Background : Hypertension is a disease characterized by end-organ complications; leading to high morbidity and mortality in many cases. People with untreated or uncontrolled hypertension often run the risk of developing complications directly associated with the disease. Left ventricular hypertrophy (LVH) has been shown to be a significant risk factor for adverse outcomes both in patients with hypertension and in the general population. We investigated the prevalence and pattern of LVH in a treated hypertensive population at the University College Hospital; Ibadan; Nigeria; using non-hypertensive subjects as control. Design and Setting : A prospective observational study performed at the University College Hospital; Ibadan; Nigeria. Methods : Patients had 6 visits; when at least one blood pressure measurement was recorded for each hypertensive subject and average calculated for systolic blood pressure (SBP) and diastolic blood pressure (DBP) separately. The values obtained were used for stratification of the subjects into controlled and uncontrolled hypertension. Subjects also had echocardiograms to determine their left ventricular mass. Results : LVH was found in 14 (18.2) of the normotensive group; 40 (20.8) of the uncontrolled hypertensive group and 14 (24.1) of the controlled hypertensive group when left ventricular mass (LVM) was indexed to body surface area (BSA). When LVM was indexed to height; left ventricular hypertrophy was found in none of the subjects of the normotensive group; while it was found present in 43 (22.4) and 14 (24.1) subjects of the uncontrolled and controlled hypertensive groups; respectively. Significant difference in the prevalence of LVH was detected only when LVM was indexed to height alone. Conclusion : Clinic blood pressure is an ineffective way of assessing BP control. Thus in apparently controlled hypertensive subjects; based on office blood pressure; cardiac structural changes do remain despite antihypertensive therapy. This population is still at risk of cardiovascular events

Electrocardiographic Left Ventricular Hypertrophy with Strain Pattern : Prevalence; Mechanisms and Prognostic Implications : Review Article

Background: Electrocardiographic left ventricular hypertrophy with strain pattern has been documented as a marker for left ventricular hypertrophy. Its presence on the ECG of hypertensive patients is associated with a poor prognosis. This review was undertaken to report the prevalence; mechanism and prognostic implications of this ECG abnormality. Materials and methods: We conducted a comprehensive search of electronic databases to identify studies relating to the title of this review. The search criteria were related to the title. Two of the reviewers independently screened the searches. Results: Results were described qualitatively. The data were not pooled because there were no randomised studies on the topic. The prevalence of ECG strain pattern ranged from 2.1 to 36. The highest prevalence was reported before the era of good antihypertensive therapy. The sensitivity as a measure of left ventricular hypertrophy ranged from 3.8 to 50; while the specificity was in the range of 89.8 to 100. Strain pattern was associated with adverse cardiovascular risk factors as well as increased all-cause and CV morbidity and mortality. ST-segment depression and T-wave inversion on the ECG was recognised as the strongest marker of morbidity and mortality when ECG-LVH criteria were utilised for risk stratification in hypertensive subjects. Conclusion: Electrocardiographic strain pattern identifies cardiac patients at higher risk of cardiovascular-related as well as all-cause morbidity and mortality

Profile of chloroquine - induced pruritus in Nigerian children resident in Ibadan, Nigeria

Chloroquine is still the first-line drug in the treatment of malaria in Nigeria and West- Africa sub-region. A major drawback to the use of chloroquine is pruritus. We studied a total of 175 children aged 1­15 years with a view to assessing some factors that may influence chloroquine induced pruritus and the possible impact on therapy with this drug. The mean age was 5.2+4.0 and there were 87 females and 88 males. Chloroquine-induced pruritus was found in 43/175 (24.6%). All the subjects experienced the itching within 24 hours of ingestion of the drug and median duration of the itching was 2 days. Majority of those who itched still used chloroquine to treat malaria for various reasons. There was positive family history in 34/43 (79%) of those who itched and 57/132 (43%) of those who did not itch to chloroquine. Those who had chloroquine-induced pruritus were relatively older (mean age 6.90+3.68 years versus 4.64+4.00; p< 0.05) and mean age onset of chloroquine-induced pruritus was positively associated with mean age of the children r = 0.91; 95% confidence limits: 0.71< r < 0.91. We concluded that chloroquine-induced pruritus in this group of children evolved with increasing age and was associated with positive family history
