Stigma in Ethiopia: association with depressive symptoms in people with HIV

Rates of depression among people living with HIV can be as high as 50%. In many settings, HIV-related stigma has been associated with depressive symptoms which may lead to poor engagement in care and ultimately, poorer health outcomes. Stigma is a major issue in Ethiopia but data examining the relationship between stigma and depression in Ethiopia are lacking. We performed a mixed-methods cross-sectional study to examine the relationship between stigma of HIV/AIDS and depressive symptoms in Gondar, Ethiopia. We interviewed patients who presented for routine HIV care at Gondar University Hospital during the study period, examining depressive symptoms and HIV/AIDS-related stigma using standardized measures. Multiple-regression was used to assess the relationship between depressive symptoms, stigma, and gender. Of 55 patients included in this analysis, 63.6% were female and most participants had limited formal education (69%, less than 12th grade education). The majority reported experiencing both stigma (78%) and depressive symptoms (60%) ranging in severity from mild to moderately severe. Higher levels of HIV-related stigma were significantly associated with higher levels of depressive symptoms (β = 0.464, p ≤ 0.001). Although gender was associated with stigma, it was not associated with depressive symptoms (β = ?0.027, p > 0.05). Results suggest the importance of psychosocial issues in the lives of people with HIV in Ethiopia.     

Replication Kinetics for a Reporter Merkel Cell Polyomavirus

Merkel cell polyomavirus (MCV) causes one of the most aggressive human skin cancers, but laboratory studies on MCV replication have proven technically difficult. We report the first recombinase-mediated MCV minicircle (MCVmc) system that generates high levels of circularized virus, allowing facile MCV genetic manipulation and characterization of viral gene expression kinetics during replication. Mutations to Fbw7, Skp2, β-TrCP and hVam6p interaction sites, or to the stem loop sequence for the MCV-encoded miRNA precursor, markedly increase viral replication, whereas point mutation to an origin-binding site eliminates active virus replication. To further increase the utility of this system, an mScarlet fusion protein was inserted into the VP1 c-terminus to generate a non-infectious reporter virus for studies on virus kinetics. When this reporter virus genome is heterologously expressed together with MCV VP1 and VP2, virus-like particles are generated. The reporter virus genome is encapsidated and can be used at lower biosafety levels for one-round infection studies. Our findings reveal that MCV has multiple, self-encoded viral restriction mechanisms to promote viral latency over lytic replication, and these mechanisms are now amenable to examination using a recombinase technology.     

Phenotypic traits of the hypothalamic PVN cells innervating airway-related vagal preganglionic neurons

The paraventricular nucleus of the hypothalamus (PVN) integrates multiple inputs via projections from arginine vasopressin (AVP)- and oxytocin (OXT)-containing neurons to the brain stem and spinal cord as well as regulates respiratory and cardiovascular stress-related responses, which also affect airway function. In the present study, we used immunocytochemistry and the retrograde transneuronal tracer, Bartha strain of pseudorabies virus expressing green fluorescent protein (PRV-GFP), to localize AVP- and OXT-producing neurons that project to airway-related vagal preganglionic neurons (AVPNs) innervating intrapulmonary airways. PRV-GFP was microinjected into the upper right lung lobe, and after 4 days survival, hypothalamic tissue sections were processed for co-expression of PRV-GFP and AVP or PRV-GFP and OXT. In addition, in a separate group of five rats, Phaseolus vulgaris leucoagglutinin (PHAL), an anterograde tracer, was injected unilaterally into the PVN and cholera toxin beta subunit was microinjected into the tracheal wall. Analysis of five successfully infected animals showed that 14% of PRV-GFP labeled neurons express AVP traits and 18% of transneuronally-labeled neurons contain OXT. Furthermore, the identified AVPNs innervating extrathoracic trachea receive axon terminals of the PVN neurons. The results indicate that AVP- and OXT-producing PVN cells, via direct projections to the AVPNs, could modulate cholinergic outflow to the airways, as a part of overall changes in response to stress.

Involving religious leaders in HIV care and treatment at a university-affiliated hospital in Ethiopia: Application of formative inquiry

In sub-Saharan Africa, religious views strongly influence how people relate to illness, health, and healing. Belief in the curative power of religion, including for HIV, persists in many communities. As such, many funding agencies and organisations working in the field of HIV have incorporated religious institutions into their programmes in various capacities. Yet, debate continues regarding the benefits and drawbacks of including sectarian organisations in the fight against HIV. In the current study, we sought to explore whether patients with HIV would be amenable to receiving HIV-related psychosocial support from religious leaders. We interviewed 48 Ethiopian Orthodox Church followers who presented for routine HIV care at Gondar University Hospital ART (antiretroviral treatment) clinic. Although almost half (46%) of participants self-identified as ‘very religious’, the majority of them (73%) had not disclosed their HIV status to a religious leader. Study participants highlighted multiple factors that could potentially affect their willingness to involve religious leaders in their HIV care. We discuss these findings in relation to religion and HIV in the African context. Our findings support the use of formative qualitative work prior to developing and implementing programmes that integrate faith and medical communities.     

Adherence to antihypertensive treatment and associated factors among patients on follow up at University of Gondar Hospital, Northwest Ethiopia

ABSTRACT: BACKGROUND: Hypertension is an overwhelming global challenge with high morbidity and mortality rates. In Ethiopia 6% and Addis Ababa, 30% of the population has been estimated to have hypertension. Poor adherence is associated with bad outcome of the disease and wastage of healthcare resources. In Ethiopia, particularly in the study area little is known about treatment adherence and associated factors. Therefore this study aimed to assess adherence to antihypertensive therapy and associated factors among HTN patients on follow up at University of Gondar Referral Hospital. METHOD: Institution based cross sectional study was conducted. Systematic sampling technique was used to select 384 participants. A structured standard questionnaire was used after some modifications. Morisky Medication Adherence Scale was used for labeling patients as adherent or non-adherent. Data were entered and analyzed using SPSS version 16. RESULTS: Only 64.6% of the study subjects were found to be adherent to their treatment. Sex (AOR=0.48, 95%CI = 0.28, 0.82), knowledge about HTN and its treatment (AOR=6.21, 95%CI=3.22, 11.97), distance from the hospital (AOR = 2.02, 95% CI =1.19-3.43) and co morbidity (AOR=2.5, 95%CI=1.01, 6.21) variables were found significantly associated with treatment adherence. Conclusion and Recommendations: Only 64.6% of the study subjects were found to be adherent to their treatment. Factors such as sex, distance from the hospital, number of co morbidities, Knowledge about HTN and its treatment were associated with adherence behavior of patients. Early diagnosis and management of co morbidities, adherence counseling and patient education about the disease and its treatment are important to improve adherence status of patients.     

The latent structure of generalized anxiety disorder in midlife adults

Generalized anxiety disorder (GAD) is identified as a discrete disorder in the DSM-5, but evidence suggests that GAD and the related construct of pathological worry possesses a dimensional latent structure. The objective of this study was to ascertain the latent structure of GAD using taxometric methods. A subsample of adults (N=2061) from the Midlife in the United States Study, a national sample of Americans, provided the data. Additional data from individuals who were re-interviewed 10 year later (n=1228) were also analyzed. Items corresponding to the DSM-IV-TR diagnostic criteria for GAD were used to generate indicators for the taxometric analyses. Multiple taxometric procedures provided no evidence that GAD has a categorical or taxonic latent structure. Instead, the results were more consistent with the proposition that GAD exists on a continuum. Evidence that GAD is dimensional suggests that dichotomizing individuals into GAD versus non-GAD groups will typically result in decreased statistical power. They also suggest that any diagnostic thresholds for identifying GAD are likely to be arbitrary. The findings are consistent with models that locate GAD within the framework of extant dimensional models of personality and with research that emphasizes a multifactorial etiology for GAD.     

Epilepsy,poverty and early under-nutrition in rural Ethiopia

PurposeThe incidence of epilepsy in Ethiopia is high compared with industrialised countries, but in most cases the cause of epilepsy is unknown. Childhood malnutrition remains widespread. We performed a case–control study to determine whether epilepsy is associated with poverty and markers of early under-nutrition.MethodsPatients with epilepsy (n = 112), aged 18–45 years, were recruited from epilepsy clinics in and around two towns in Ethiopia. Controls with a similar age and gender distribution (n = 149) were recruited from patients and relatives attending general outpatient clinics. We administered a questionnaire to define the medical and social history of cases and controls, and then performed a series of anthropometric measurements. Unconditional logistic regression was used to estimate multivariate adjusted odds ratios. Multiple linear regression was used to estimate adjusted case–control differences for continuously distributed outcomes.ResultsEpilepsy was associated with illiteracy/low levels of education, odds ratio = 3.0 (95% confidence interval: 1.7–5.6), subsistence farming, odds ratio = 2.6 (1.2–5.6) and markers of poverty including poorer access to sanitation (p = 0.009), greater overcrowding (p = 0.008) and fewer possessions (p < 0.001). Epilepsy was also associated with the father's death during childhood, odds ratio = 2.2 (1.0–4.6). Body mass index was similar in cases and controls, but patients with epilepsy were shorter and lighter with reduced sitting height (p < 0.001), bitrochanteric diameter (p = 0.029) and hip size (p = 0.003). Patients with epilepsy also had lower mid-upper arm circumference (p = 0.011) and lean body mass (p = 0.037).ConclusionEpilepsy in Ethiopia is strongly associated with poor education and markers of poverty. Patients with epilepsy also had evidence of stunting and disproportionate skeletal growth, raising the possibility of a link between early under-nutrition and epilepsy.
