Citalopram and fluoxetine affects blood chemistry, hematology and brain serotonin in rats.

BACKGROUND: Depression is caused as a result of combination of genetic, biochemical, environmental, and psychological factors. Citalopram and fluoxetine are antidepressants which are considered the current standard for depression treatment. There are little or no reports as to whether these antidepressants affect blood chemistry and haematological parameters in humans. OBJECTIVE: The effects of citalopram and fluoxetine on blood chemistry, hematology and brain serotonin in rats were investigated. METHODS: Forty-five Sprague Dawley male albino rats (140.69 +/- 5.86g) were divided into 3 equal groups. The first group of rats were orally administered 2 ml of 0.25 mg/ml of citalopram, the second group was administered 2 ml of 0.25 mg/ml of fluoxetine and the third group was administered 2 ml of saline (0.89% NaCl) daily for 4 weeks. The body weights and feed intake of rats were recorded every other day throughout the duration of drug administration. Five rats from each group were sacrificed by cervical dislocation after 7, 14, 21 and 28 days of drug administration. Blood was taken intravenously into lithium heparinized tubes and brain excised. Blood chemistry and hematology were determined by auto analyzer, while brain serotonin levels were determined using High Performance Liquid Chromatography. Serum levels of creatinine, urea, albumin, protein, glucose and activities of aspartate aminotransferase (AST) and alanine amino transferase (ALT) were determined in rats administered citalopram, fluoxetine and saline. The packed cell volume, white blood cells, red blood cells and platelets of rats administered the respective drugs were determined. RESULTS: There was no significant (P > 0.01) difference in the mean body weight of rats administered fluoxetine, citalopram or saline for 2 weeks. There were no significant differences in the hematological parameters of rats. The results of the study showed that citalopram increase the body weight of rats in the third and fourth week and was reduced in fluoxetine administered rats. The drugs also affected brain serotonin level, lipid profile of rats and increased levels of albumin, glucose and activities of liver enzymes; aspartate aminotransferase and alanine aminotransferase. CONCLUSION: Data of the study indicate that oral administration of citalopram and fluoxetine in rats for 4 weeks daily affected blood chemistry and do not affect haematological parameters.

Factors associated with anxiety disorders among HIV-positive attendees of an HIV clinic in Lagos, Nigeria.

Anxiety disorders (ADs) occurring in people living with HIV/AIDS (PLWHA) are often poorly identified in spite of the untold consequences that may result if not diagnosed and treated promptly. This study aimed to describe factors associated with ADs among PLWHA. Three hundred participants were administered sociodemographic/clinical profile questionnaires, and diagnoses of ADs were made using Schedule for Clinical Assessment in Neuropsychiatry (SCAN) based on International Classification of Diseases, 10th edition (ICD-10) criteria. In this study, 65 (21.7%) participants were diagnosed with ADs. A lack of family support, unemployment, younger mean age and being unmarried (P < 0.05) were factors associated with ADs in PLWHA; however, lack of family support (odds ratio [OR] = 0.458, 95% confidence interval [CI] = 0.254-0.827, P = 0.010), being unmarried (OR = 1.930, 95% CI = 1.046-3.560, P = 0.035) and unemployment (OR = 0.495, 95% CI = 0.264-0.926, P = 0.028) were the only factors that remained significant following logistic regression analysis. Prompt identification with active management of ADs and their associated factors among PLWHA are advocated. Further research on the risk factors for ADs is also warranted.

Burden and psychological effects: caregiver experiences in a psychiatric outpatient unit in Lagos, Nigeria.

OBJECTIVE: Worldwide, research into experiences of care givers are gradually increasing and their central role in community care is being acknowledged. Caregivers experience a multidimensional range of problems, often associated with their caregiving role. It becomes important to identify these areas of burden and provide necessary support. The study sought to determine the prevalence of psychological distress and experience of burden of care among the caregivers of mentally ill patients. METHOD: A cross sectional descriptive study. Eligible consecutive subjects were recruited to the study over a 6 month period. Fifty three caregiver relatives of patients diagnosed with a psychiatric illness were assessed using the General Health questionnaire version 12, an Adapted Burden of Care (BOC) Schedule and a Sociodemographic questionnaire. RESULTS: The caregivers were 51% male and 49% female. Most were above 35years in age (66.1%). They were either parents (38.8%), siblings (18.4%), uncle/aunt (14.3%), first cousin (12.2%) or other extended relatives (16.3%). Almost half of the relatives had psychological distress (43.8%) and most of which (63%) had more burden. The mean score on the BOC among the caregivers was 41 (±18.68SD), with scores ranging from 0.00-89.00, and 45.3% of relatives experiencing more than average burden of care. CONCLUSION: There is a significant level of burden and psychological distress experienced by caregivers in this study location. It is recommended that effectively planned interventions are targeted at alleviating this burden and at improving the ability of caregivers to cope, within the Nigerian mental health service delivery system.
