Suicidal behaviour among patients with congestive cardiac failure in a Nigerian teaching hospital.

Background: Suicidal behaviour is an established psychiatric complication of congestive cardiac failure (CCF), contributing significantly to morbidity and death by suicide. The magnitude and risk factors for suicidal behaviour among patients with CCF are yet to be unpacked, especially in developing nations such as Nigeria. Aim: To determine the prevalence of suicidal behaviour and the risk factors associated with suicidal behaviour, among patients with CCF in Nigeria. Setting: Cardiology outpatient clinic of Lagos State University Teaching Hospital, Lagos, Nigeria. Methods: A cross-sectional study was conducted among 98 randomly selected patients with a diagnosis of CCF. Participants were assessed with a socio-demographic and clinical factors questionnaire and Beck Scale of Suicidal Ideation. Chi-square test, t-test and logistic regression were used to analyse data. Results: The prevalence of suicidal ideation and suicidal attempt among patients with CCF was 52% and 1%, respectively. No socio-demographic factor was significantly associated with suicidal ideation. Clinical factors associated with suicidal ideation were age at diagnosis (p = 0.042), aetiology of CCF (p = 0.001) and severity of CCF (p = 0.032). Only the severity of CCF (odds ratio [OR] = 20.557, p = 0.014) predicted suicidal ideation among patients with CCF. Conclusion: Suicidal behaviour constitutes a huge burden among the outpatient CCF population. The identification of clinical risk factors for suicidal ideation (age at diagnosis, aetiology and severity of CCF) further illuminates a pathway to mortality among patients with CCF. Contribution: The findings lend a voice to the need for screening for suicidal behaviour, suicide prevention programmes, surveillance systems and government policies that support mental health for patients with CCF.

Pattern of arrhythmias among Nigerians with congestive heart failure.

BACKGROUND: In patients with heart failure, death is often sudden due to life-threatening arrhythmias. This work was carried out to evaluate the pattern of arrhythmias in Nigerians with heart failure. MATERIALS AND METHODS: Thirty subjects with congestive heart failure (CHF), 30 subjects with hypertensive heart disease, and 15 normal subjects with no obvious features of heart disease were evaluated with resting and 24-hour electrocardiographic monitoring and transthoracic echocardiography. Data were analyzed with one-way analysis of variance with post hoc Duncan's analysis, Fisher's exact test, and linear regression analysis using SPSS version 16. RESULTS: CHF subjects had more instances of supraventricular tachycardia (P=0.005), ventricular extrasystoles (P<0.001), bigeminy (P<0.001), trigeminy (P<0.001), couplets (P<0.001), triplets (P<0.001), and nonsustained ventricular tachycardia (VT) (P=0.003) than the other two control groups. They also showed a significantly longer VT duration (4.6±5.6 seconds) compared with the other groups (P<0.001). Linear regression analysis showed a significant direct relationship between VT and the maximum number of ventricular extrasystoles per hour (P=0.001). CONCLUSION: Cardiac arrhythmias are common in subjects with CHF and are more frequent when compared with patients with hypertensive heart disease and normal subjects.

The effect of psychological distress on medication adherence in persons with HIV infection in Nigeria.

BACKGROUND: A high level of adherence to prescribed antiretroviral (ARV) regimens is required to achieve and maintain suppression of human immunodeficiency virus (HIV) replication and prevent drug resistance. OBJECTIVE: This study aimed to determine the possible relationship between psychopathology and ARV medication adherence in Nigeria. METHOD: Persons with HIV infection (N=182) completed various questionnaires on sociodemographic and clinical details, general psychopathology, self-esteem, and medication adherence. RESULTS: Low medication adherence was reported in 26.9% of the participants; significant correlates included presence of psychopathology and perceived poor social support. CONCLUSION: The success of any intervention policy for HIV-infected persons in sub-Saharan Africa must consider both low level of medication adherence and its associated factors.

Post-traumatic stress disorder (PTSD) after stigma related events in HIV infected individuals in Nigeria.

BACKGROUND: One of the most distressing concerns of many people living with HIV in sub-Saharan Africa is the stigma. Intense stigma may be traumatic. This study aimed to investigate the probability and correlates of Posttraumatic stress disorder (PTSD) following intense stigmatizing events and situations in HIV infected individuals in Nigeria. METHODS: Adult sero-positive attendees of an HIV care centre (N = 190) completed questionnaires regarding sociodemographic and clinical details; the 12-item General Health Questionnaire (GHQ-12) and the Rosenberg's Self-Esteem Scale. The clients were then interviewed for the presence of stigma related PTSD with a modified version of the mini international neuropsychiatry interview (MINI). RESULTS: About 2/3 of the participants had experienced at least an intense HIV-related stigmatizing event or situation. The rate of HIV-stigma related PTSD was 27.4%. Independent predictors of HIV stigma-related PTSD included past history of traumatic events (Single event, OR 2.28, 95% CI 1.08-4.73; Multiple events, OR 9.47, 95% CI 2.97-32.20), low self esteem (OR 6.52, 95% CI 2.59-16.55), poor level of social support (OR 3.33, 95% CI 1.24-9.79) and presence of general psychopathology (OR 2.18, 95% CI 1.07-4.44). CONCLUSION: PTSD may not be specific to traumatic events alone. There is a possibility of PTSD after an intense stigmatizing event or situation. While the validity for the validity of HIV-stigma related PTSD warrants further investigation, stigma needs to be considered when planning rehabilitation strategies for HIV infected individuals in sub-Saharan Africa. A closer attention to self esteem, level of social support and presence of psychopathology is needed in these individuals.

Relationship between depression and quality of life in persons with HIV infection in Nigeria.

OBJECTIVE: Despite the fact that two-thirds of all the people with HIV live in sub-Saharan Africa, little is known about the emotional state and quality of life (QOL) of subjects with HIV in this region. The objective of this study was to evaluate the association between clinical depression and quality of life in a group of HIV sero-positive subjects in Nigeria. METHODS: Subjects with HIV infection (n = 87) completed a questionnaire detailing sociodemographic and HIV related variables. The subjects were assessed for the diagnosis of depression using the Mini International Neuropsychiatric Interview (MINI) and their subjective health related quality of life (QOL) was assessed using the short version of the WHO quality of life scale (WHOQOL-BREF). RESULTS: There were 25 (28.7%) subjects with diagnosis of depression. Lower educational level correlated with poorer QOL in all the domains of WHOQOL-BREF except the "social relationship" domain. Also, poor social support correlated with poorer QOL scores on domains of "physical health" and "social relationship" and presence of medical problems was significantly associated with poorer scores on domains of "physical health" and "psychological health." Diagnosis of depression was significantly correlated with poorer QOL in all domains except the "social relationship" domain. CONCLUSION: Poorer health related QOL in Nigerian subjects with HIV was associated with depression, lower educational and socioeconomic levels, and poor social support. Early identification and referral of patients with depression needs to be incorporated into intervention programs designed for HIV infected individuals in this region.

Psychiatric disorders among the HIV-positive population in Nigeria: a control study.

OBJECTIVE: This article estimates the point prevalence of psychiatric disorders in a sample of HIV-positive subjects in Nigeria in comparison with normal HIV-negative controls and evaluates the possible sociodemographic and clinical correlates of psychiatric disorders in HIV-positive subjects. METHODS: HIV-positive subjects (n=88) and HIV-negative healthy controls (n=87) were assessed for their current diagnosis of DSM-IV psychiatric disorders via the Mini International Neuropsychiatric Interview. Sociodemographic and clinical details were also obtained. RESULTS: The rate of psychiatric disorders in subjects with HIV was 59.1% compared to 19.5% in subjects without HIV infection [odds ratio (OR)=5.95, 95% confidence interval (CI)=3.02-11.75]. The subjects with HIV had significantly higher rates of affective disorders (OR=3.58, 95% CI=1.44-8.94), anxiety disorders (OR=3.57, 95% CI=1.65-7.72), and psychotic disorders (OR=1.10, 95% CI=1.01-1.12) than healthy controls. The factors significantly associated with psychiatric disorders include poor level of social support and stage of the disease. CONCLUSION: Psychiatric disorders are common in our Nigerian subjects with HIV, and the rates are significantly higher when compared to the healthy general population. Proactive identification and treatment of mental disorders should be integrated into HIV intervention policies in this region.
