The aim of this study was to construct and validate a visual depression screening instrument in a setting of low literacy and a high burden of HIV/AIDS. We engaged the help of a fine artist to draw pictures depicting DSM-IV-TR criteria for a depressive episode. We then validated this instrument named the Akena's visual depression inventory (AVIDI), in 92 persons living with HIV/AIDS in Uganda. The performance of the AVIDI in those with high and low education levels was determined. The area under curve (AUC) score of the AVIDI was 0.82. There was no difference between the AUC scores in persons with lower versus higher education levels. The AVIDI demonstrated a good psychometric property and can therefore be used to screen for depression in settings with higher rates of illiteracy.

Methods This is an international multicentre cross-sectional study conducted in 25 hospitals across 11 countries. The research team at each study site approached a consecutive target sample of 30 discharged patients to measure their satisfaction using the five-item study-specific questionnaire. Individual and institution level correlates of 'low satisfaction' were examined by comparisons of binary and multivariate associations in multilevel regression models.

There is limited information on the effect of older age (.50 years) at ART initiation on patient retention in ART programs in Uganda. This study aimed to investigate demographic and clinical differences between older and younger human immunodeficiency virus (HIV)-positive individuals prior to ART initiation and then to assess the effect of older age at ART initiation on patient retention in an ART program. Methods: A retrospective chart review of all medical charts belonging to 773 HIV-positive individuals who initiated ART from January 2005 through July 2009 was conducted. Factors associated with older HIV-positive individuals were determined using simple and multivariate logistic regression. Survival analysis techniques were used to compare median survival times in the ART program between older and younger HIV-positive individuals. Cox regression models were used to assess the impact of older age on patient retention while adjusting for variables associated with both older age and patient retention. Results: Older HIV-positive individuals were significantly more likely to have a clinical diagnosis of HIV-related dementia (odds ratio [OR] = 7.65; P = 0.037), severe mental illness (OR = 1.28; P = 0.39), peripheral neuropathy, (OR = 3.76; P = 0.024), and HIV wasting syndrome (OR = 1.92; P = 0.023). Median survival time for older HIV-positive individuals was eight months longer than that of their younger counterparts (log-rank χ 2 = 3.3, P = 0.45) Independent predictors of loss to follow-up were a clinical diagnosis of HIV-related dementia (hazards ratio [HR] = 4.63; P = 0.000), severe mental illness (HR = 1.44; P = 0.005), and HIV wasting syndrome (OR = 1.35; P = 0.008). Conclusion: There was no difference in patient retention rates between younger and older HIV-positive individuals. However, a clinical diagnosis of HIV dementia, severe mental disorder, HIV wasting syndrome, and CD4 counts less than 200 were independent predictors of low patient retention rates in this ART program.

Task-shifting, protocolized approaches to depression care have been used to overcome severe shortages of mental health specialists in developing countries, but not in sub-Saharan Africa and not with HIV clients. The aims of this trial are to evaluate the implementation outcomes and cost-effectiveness of a task-shifting, protocolized model of antidepressant care for HIV clinics in Uganda. Methods/Design: INDEPTH-Uganda is a cluster randomized controlled trial that compares two task-shifting models of depression care -a protocolized model versus a model that relies on the clinical acumen of trained providers to provide depression care in ten public health HIV clinics in Uganda. In addition to data abstracted from routine data collection mechanisms and supervision logs, survey data will be collected from patient and provider longitudinal cohorts; at each site, a random sample of 150 medically stable patients who are depressed according to the PHQ-2 screening will be followed for 12 months, and providers involved in depression care implementation will be followed over 24 months. These data will be used to assess whether the two models differ on implementation outcomes (proportion screened, diagnosed, treated; provider fidelity to model of care), provider adoption of treatment care knowledge and practices, and depression alleviation. A cost-effectiveness analysis will be conducted to compare the relative use of resources by each model.

We assessed the impact of antidepressant therapy on measures of work, condom use, and psychosocial well-being among depressed HIV clients in Uganda. Methods: Paired t-tests and McNemar tests were used to assess change in survey data collected from participants at initiation of antidepressant therapy (baseline) and 6 months later. Results: Ninety-five participants completed the 6-month assessment, of whom 82 (86%) responded to treatment (defined as Patient Health Questionnaire-9 score < 5). Among study completers, work functioning improved significantly, as did measures of self-efficacy related to condom use and work (as well as general self-efficacy), and internalized HIV stigma declined; however, actual engagement in work activity and consistent condom use did not show significant change. Similar findings were observed among treatment responders. Conclusions: Antidepressant treatment benefits functional capacity, psychological well-being, and cognitive intermediary factors that may be essential for behavioral change related to work and condom use, but supplementary therapeutic strategies may be needed to impact more direct behavioral change.

However there has been no systematic review on non-prescription antimicrobial use in these settings. This review thus intended to establish the burden, risk factors and effects of antimicrobial self-medication in Low and Middle Income Countries. Methods: In 2012, we registered a systematic review protocol in PROSPERO (CRD42012002508). We searched PubMed, Medline, Scopus, and Embase databases using the following terms; "self-medication", "non-prescription", 'self-treatment', "antimicrobial", "antimalarial", "antibiotic", "antibacterial" "2002-2012" and combining them using Boolean operators. We performed independent and duplicate screening and abstraction of study administrative data, prevalence, determinants, type of antimicrobial agent, source, disease conditions, inappropriate use, drug adverse events and clinical outcomes of antibiotic self-medication where possible. We performed a Random Effects Meta-analysis. Results: A total of thirty four (34) studies involving 31,340 participants were included in the review. The overall prevalence of antimicrobial self-medication was 38.8 % (95 % CI: 29.5-48.1). Most studies assessed non-prescription use of antibacterial (17/34: 50 %) and antimalarial (5/34: 14.7 %) agents. The common disease symptoms managed were, respiratory (50 %), fever (47 %) and gastrointestinal (45 %). The major sources of antimicrobials included, pharmacies (65.5 %), leftover drugs (50 %) and drug shops (37.5 %). Twelve (12) studies reported inappropriate drug use; not completing dose (6/12) and sharing of medicines (4/12). The main determinants of antimicrobial self-medication include, level of education, age, gender, past successful use, severity of illness and income. Reported negative outcomes of antimicrobial self-medication included, allergies (2/34: 5.9 %), lack of cure (4/34: 11.8 %) and causing death (2/34: 5.9 %). The commonly reported positive outcome was recovery from illness (4/34: 11.8 %). Conclusion: The prevalence of antimicrobial self-medication is high and varies in different communities as well as by social determinants of health and is frequently associated with inappropriate drug use.

This study examined the effectiveness of antidepressant treatment and predictors of treatment response among depressed HIV patients in Uganda. Data was obtained from two open label trials in which 184 HIV patients were diagnosed with depression and started on antidepressants. Data at treatment baseline and month 6 were compared to assess treatment response, and baseline predictors of response were assessed. 154 completed Month 6, of whom 122 (79%) had responded to treatment and were no longer depressed (Patient Health Questionnaire-9 score < 5). Bivariate analysis found that education, CD4 count, general health functioning, physical health, pain, quality of life, and social support variables were associated with antidepressant treatment response; however, only secondary education and social support independently predicted treatment response in logistic multiple regression analysis. Baseline depression severity was not associated with treatment response. In conclusion, antidepressants are effective in treating both moderate and more severe depression among persons living with HIV in Uganda, and education [O.R. (95% C.I.) = 4.33 (1.33 -14.11)] and social support [O.R. (95% C.I.) = 1.54 (1.03 -2.30)] were most predictive of treatment response.

The effect of depression screening on case detection, and rates of antidepressant prescription is unknown.We assessed 368 participants for major depressive disorder, and provided clinicians with the results. Four weeks later, we abstracted information from the charts of the depressed patients to ascertain if they received antidepressants. We also randomly sampled the charts of 368 non-screened patients, to ascertain whether clinicians had diagnosed and prescribed antidepressant treatment.Major depressive disorder was identified in 17.9 % of the screened group, and in 2.1 % of the non-screened group [OR = 9.65, CI = (4.54-20.50)]. The screened individuals were 7.8 times more likely to receive antidepressants (95 % CI = 3.04-20.24). Identification of major depressive disorder by clinicians in HIV settings remains poor. However, routine screening can improve case detection rates and the proportion of patients receiving antidepressants.

The Patient Health Questionnaire (PHQ-9) was used to classify depressive severity (none, minor and major depression) and symptom type (cognitive and somatic). Condom use was assessed over the past 6 months and during the last episode of sexual intercourse.

However, little research has examined whether depression alleviation improves work-related outcomes in this population, which is the focus of this analysis. Method A sample of 1028 depressed HIV clients in Uganda enrolled in a comparative trial of depression care models and were surveyed over 12 months. Serial regression analyses examined whether depression alleviation (measured by the nine-item Patient Health Questionnaire) was associated with change in self-reported weekly amount of hours worked and income earned, and whether these relationships were mediated by change in work-related self-efficacy. Results Among those with major depression, depression alleviation was associated with nearly a doubling of weekly hours worked in bivariate analysis. The relationship between depression alleviation and hours worked was partially mediated by change in work self-efficacy among those with major depression, as well as those with minor depression, in multivariate regression analysis that controlled for demographic and health covariates. Depression alleviation was not significantly associated with change in weekly income. Conclusion These findings suggest that depression alleviation benefits work functioning at least in part through improved confidence to engage in work-related activities. Integration of depression care services into HIV care may be important for improving the economic well-being of people living with HIV.

Both brief and long depression screening instruments have been validated in low and middle income countries (LMIC), including within HIV care settings. However, it remains unknown whether the brief instruments validated in LMIC are as accurate as the long ones. Methods: We conducted a search of PUBMED, the COCHRANE library, AIDSLINE, and PSYCH-Info from their inception up to July 2011, for studies that validated depression screening instruments in LMIC. Data were extracted into tables and analyzed using RevMan 5.0 and STATA 11.2 for the presence of heterogeneity. Results: Nineteen studies met our inclusion criteria. The reported prevalence of depression in LMIC ranged from 11.1 to 53%. The area under curve (AUC) scores of the validated instruments ranged from 0.69-0.99. Brief as well as long screening instruments showed acceptable accuracy (AUC≥0.7). Five of the 19 instruments were validated within HIV settings. There was statistically significant heterogeneity between the studies, and hence a meta-analysis could not be conducted to completion. Heterogeneity chi-squared = 189.23 (d.f. = 18) p<.001. Conclusion: Brief depression screening instruments in both general and HIV-PHC are as accurate as the long ones. Brief scales may have an edge over the longer instruments since they can be administered in a much shorter time. However, because the ultra brief scales do not include the whole spectrum of depression symptoms including suicide, their use should be followed by a detailed diagnostic interview.

It's still questionable whether HIV related depression is clinically different from depression in HIV-negative populations, a fact that could have treatment implications.This study compared the clinical features of major depression between HIV-Positive and HIV-negative patients with a view to intervention strategies. Method: A comparative, descriptive, cross-sectional study was carried out on 64 HIV-Positive depressed patients and 66 HIV-negative depressed patients in Butabika and Mulago hospitals. They were compared along the parameters of clinical features of depression, physical examination and laboratory findings. Pair wise comparisons, logistic regression and Multivariate analysis were done for the two groups on a number of variables. Results: Compared to HIV-Negative patients, HIV-Positive patients were more likely to be widowed ; older (≥ 30years), less likely to have a family member with a mental illness; a later onset of depressive illness (≥30years); more likely to have a medical illness and taking medication before onset of depressive, symptomatically compared to HIV-Negative patients, HIV-Positive patients were more critical of themselves ; had significantly more problems making decisions ; had poorer sleep; felt more easily tired; more appetite changes; more cognitive impairment. Low CD4 counts were not significantly associated with depression, but HIV related depression was more likely to occur in stages II and III illness. Conclusion: These findings show that the clinical and associated features of depression differ between HIV-Positive and HIV-Negative patients, thus requiring different management approaches and further studies related to HIV-related depression.
