Prevalence of hepatitis B and C and relationship to liver damage in HIV infected patients attending Joint Clinical Research Centre Clinic (JCRC), Kampala, Uganda.

Background: Hepatitis B and C viruses cause death due to liver disease worldwide among Human Immunodeficiency Virus (HIV) positive individuals. Hepatitis B (HBV) and HIV have similar routes of transmission primarily; sexual, intravenous injections and prenatal while hepatitis C (HCV) is transmitted mainly through blood transfusion. Human immunodeficiency virus increases the pathological effect of hepatitis viruses and potentiates re-activation of latent hepatitis infections as a result of reduced immunity. The increase in use of antiretroviral (ARVs) drugs has led to longer period for patient survival and apparent increase in liver disease among HIV positive individuals.Objective: This study aimed at determining the prevalence of HBV, HCV, their co-infection with HIV and their effect on liver cell functionMethod: This was a cross sectional study conducted at the Joint Clinical Research Centre (JCRC) among HIV positive individuals attending the clinic. Patients were enrolled after obtaining a signed informed consent or assent for children below 17 years. Serum samples were collected for detection of Hepatitis B surface antigen (HBsAg), HCV specific antibodies and alanine aminotransferase (ALT) liver enzyme.Results: Of the 89 patients enrolled, 20 (22.5%) had at least one hepatitis virus, 15 tested positive for HBsAg (16.9%) and 5 for HCV (5.6%), one had both viruses. Hepatitis B was more prevalent among women (13 out of 57, 22.8%) than men, (2 out of 32, 6.2%), while HCV was higher among men (4 out of 32, 12.5%) than women (1 out of 57, 1.8%). Seven of 89 patients (7.9%) had elevated ALT, indicative of liver cell injury. Of these with liver cell injury, one individual tested positive for HBsAg and another one individual tested positive for HCV specific antibodies.Conclusion: The prevalence of HBV is high in HIV positive individuals with more women commonly infected. The Prevalence of HCV is lower than that of HBV with more men commonly infected. Co-infection of Hepatitis B and C viruses was uncommon. This study reveals a high prevalence of liver cell injury among HIV positive individuals although the injury due to HBV or HCV infection was lower than that which has been documented. From this study, the high prevalence of HBV and HCV among HIV positive individuals point to a need for screening of HIV positive individuals for the hepatitis viruses.Key words: Hepatitis B virus, HBV surface antigen, Hepatitis C virus, Hepatitis C virus antibodies, HIV, Liver damage

Integration of Mental Health into Primary Health Care in a rural district in Uganda

Objective: Mental health has been identified as a major priority in the Ugandan Health Sector Strategic Plan. Efforts are currently underway to integrate mental health services into the Primary Health Care system. In this study, we report aspects of the integration of mental health into primary health care in one rural district in Uganda. Method: Qualitative methods were used for data collection. Semi-structured interviews and focus group discussions were conducted with various stakeholders within the ministry of health as well as line ministries. Data analysis was done using Nvivo 7, specifically adopting framework analysis approach. Results: Attempts to offer organized mental health services were found to be present in only a few health facilities. The district had only a single mental health nurse, and very few General Health Workers adequately equipped with the knowledge and skills to provide mental health services. The vertical referral system was not being followed as planned and there was no evidence of any organized community interventions for those with mental disorders. The mental health nurse and a few PHC nurses however expressed interest and commitment to providing services for persons with mental illness, despite the challenges. Conclusion: Although mental healthis expected to be integrated into primary health care, mental health services in this district have not yet achieved the expected level of integration. This implies that this important policy requirement has not yet been effectively realized in this rural district, which could be the case in many other districts of a similar status. There is thus a need to direct more efforts towards realization of this important policy requirement.Key words: Mental health; Primary Health Care; Integration; Ugand

Media and Mental Health in Uganda

Objective: The media is largely regarded as an important stakeholder in health service delivery, with a great influence on publicattitudes. However, little is known about its interest in mental health and the guiding factors that influence media coverage of mentalhealth issues. This article describes the importance accorded to mental health by the media and the factors that influence mediacoverage of mental health issues in Uganda. Method: Semi-structured interviews were held with representatives from sixprominent media houses as part of the situational analysis of the mental health system in Uganda. Data was analyzed using Nvivo7 qualitative data analysis software. Results: The media was found to be interested and actively involved in health initiatives, butwith little attention devoted to mental health. Coverage and interest in mental health was noted to be mainly dependent on theindividual journalists’ interests, and mostly for personal reasons. Low interest was largely attributed to mental health beingperceived as a non-priority area, and the fact that mental illness is not a major contributor to mortality. Media coverage andreporting is guided by prioritization of the Health Department. Conclusion: The media in Uganda is an important stakeholderin the health care system with a key role of advocacy, publicity and mass education. Media houses however are less interested inmental health as evidenced by low coverage of mental health issues. This calls for advocacy and sensitization as a way ofpersuading media for more involvement in mental health initiatives.Key words: Media; Mental health; Uganda; Publi

Effect of anti-retroviral therapy on oxidative stress in hospitalized HIV-infected adults with and without TB.

BackgroundHIV infection and opportunistic infections cause oxidative stress (OS), which is associated with tissue damage. Anti-retroviral therapy (ART) is used to treat HIV and decrease the risk of opportunistic infections, but it is unclear whether ART reduces OS. Association of ART with OS was investigated.MethodsWe stratified a convenience sample of frozen serum or plasma from HIV-infected, ART-naïve (n=21); HIV-infected, ART-treated (n=14); HIV and PTB co-infected, ART-naïve (n=21); HIV and PTB co-infected, ART-treated (n=25) patients. Controls (n=21) were HIV-negative adults without TB symptoms. Concentration of OS markers namely: transaminases (ALT and AST), gamma glutamyl transpeptidase (GGT), albumin, total protein, malondialdehyde (MDA), vitamin C, and total anti-oxidant status (TAS) were determined.ResultsAST (p<0.001), GGT (p<0.001), total protein (p=0.001) and MDA (p<0.001) were higher in HIV patients compared to controls. Vitamin C (P<0.0001) and albumin (p<0.01) were lower in HIV-patients relative to controls. ART was only associated with higher albumin (p=0.001), higher GGT (p=0.02) and lower vitamin C (p=0.009). HIV and PTB co-infection was only significantly associated with higher GGT (p=0.01) and AST (p=0.03).ConclusionWe identified severe OS among HIV-patients. ART was associated with both increased and reduced markers of OS hence suggesting that ART may not attenuate OS

Metabolite changes in blood predict the onset of tuberculosis

Immunogenetics and cellular immunology of bacterial infectious disease

Concise gene signature for point‐of‐care classification of tuberculosis

There is an urgent need for new tools to combat the ongoing tuberculosis (TB) pandemic. Gene expression profiles based on blood signatures have proved useful in identifying genes that enable classification of TB patients, but have thus far been complex. Using real‐time PCR analysis, we evaluated the expression profiles from a large panel of genes in TB patients and healthy individuals in an Indian cohort. Classification models were built and validated for their capacity to discriminate samples from TB patients and controls within this cohort and on external independent gene expression datasets. A combination of only four genes distinguished TB patients from healthy individuals in both cross‐validations and on separate validation datasets with very high accuracy. An external validation on two distinct cohorts using a real‐time PCR setting confirmed the predictive power of this 4‐gene tool reaching sensitivity scores of 88% with a specificity of around 75%. Moreover, this gene signature demonstrated good classification power in HIV (+) populations and also between TB and several other pulmonary diseases. Here we present proof of concept that our 4‐gene signature and the top classifier genes from our models provide excellent candidates for the development of molecular point‐of‐care TB diagnosis in endemic areas

Stakeholder's perceptions of help-seeking behaviour among people with mental health problems in Uganda

<p>Abstract</p> <p>Introduction</p> <p>Mental health facilities in Uganda remain underutilized, despite efforts to decentralize the services. One of the possible explanations for this is the help-seeking behaviours of people with mental health problems. Unfortunately little is known about the factors that influence the help-seeking behaviours. Delays in seeking proper treatment are known to compromise the outcome of the care.</p> <p>Aim</p> <p>To examine the help-seeking behaviours of individuals with mental health problems, and the factors that may influence such behaviours in Uganda.</p> <p>Method</p> <p>Sixty-two interviews and six focus groups were conducted with stakeholders drawn from national and district levels. Thematic analysis of the data was conducted using a framework analysis approach.</p> <p>Results</p> <p>The findings revealed that in some Ugandan communities, help is mostly sought from traditional healers initially, whereas western form of care is usually considered as a last resort. The factors found to influence help-seeking behaviour within the community include: beliefs about the causes of mental illness, the nature of service delivery, accessibility and cost, stigma.</p> <p>Conclusion</p> <p>Increasing the uptake of mental health services requires dedicating more human and financial resources to conventional mental health services. Better understanding of socio-cultural factors that may influence accessibility, engagement and collaboration with traditional healers and conventional practitioners is also urgently required.</p

Risk Factors for Helminth, Malaria, and HIV Infection in Pregnancy in Entebbe, Uganda

Background: Infections during pregnancy may have serious consequences for both mother and baby. Assessment of risk factors for infections informs planning of interventions and analysis of the impact of infections on health outcomes. Objectives: To describe risk factors for helminths, malaria and HIV in pregnant Ugandan women before intervention in a trial of de-worming in pregnancy. Methods: The trial recruited 2,507 pregnant women between April 2003 and November 2005. Participants were interviewed and blood and stool samples obtained; location of residence at enrolment was mapped. Demographic, socioeconomic, behavioral and other risk factors were modelled using logistic regression. Results: There was a high prevalence of helminth, malaria and HIV infection, as previously reported. All helminths and malaria parasitemia were more common in younger women, and education was protective against every infection. Place of birth and/or tribe affected all helminths in a pattern consistent with the geographical distribution of helminth infections in Uganda. Four different geohelminths ( hookworm, Trichuris, Ascaris and Trichostrongylus) showed a downwards trend in prevalence during the enrolment period. There was a negative association between hookworm and HIV, and between hookworm and low CD4 count among HIV-positive women. Locally, high prevalence of schistosomiasis and HIV occurred in lakeshore communities. Conclusions: Interventions for helminths, malaria and HIV need to target young women both in and out of school. Antenatal interventions for malaria and HIV infection must continue to be promoted. Women originating from a high risk area for a helminth infection remain at high risk after migration to a lower-risk area, and vice versa, but overall, geohelminths seem to be becoming less common in this population. High risk populations, such as fishing communities, require directed effort against schistosomiasis and HIV infection

Neutrophil activation and enhanced release of granule products in HIV-TB immune reconstitution inflammatory syndrome

Background: Tuberculosis immune reconstitution inflammatory syndrome (TB-IRIS) remains incompletely understood. Neutrophils are implicated in tuberculosis pathology but detailed investigations in TB-IRIS are lacking. We sought to further explore the biology of TB-IRIS and, in particular, the role of neutrophils. Setting: Two observational, prospective cohort studies in HIV/TB coinfected patients starting antiretroviral therapy (ART), 1 to analyze gene expression and subsequently 1 to explore neutrophil biology. Methods: nCounter gene expression analysis was performed in patients with TB-IRIS (n = 17) versus antiretroviral-treated HIV/TB coinfected controls without IRIS (n = 17) in Kampala, Uganda. Flow cytometry was performed in patients with TB-IRIS (n = 18) and controls (n = 11) in Cape Town, South Africa to determine expression of neutrophil surface activation markers, intracellular cytokines, and human neutrophil peptides (HNPs). Plasma neutrophil elastase and HNP1-3 were quantified using enzyme-linked immunosorbent assay. Lymph node immunohistochemistry was performed on 3 further patients with TB-IRIS. Results: There was a significant increase in gene expression of S100A9 (P = 0.002), NLRP12 (P = 0.018), COX-1 (P = 0.025), and IL-10 (P = 0.045) 2 weeks after ART initiation in Ugandan patients with TB-IRIS versus controls, implicating neutrophil recruitment. Patients with IRIS in both cohorts demonstrated increases in blood neutrophil count, plasma HNP and elastase concentrations from ART initiation to week 2. CD62L (L-selectin) expression on neutrophils increased over 4 weeks in South African controls whereas patients with IRIS demonstrated the opposite. Intense staining for the neutrophil marker CD15 and IL-10 was seen in necrotic areas of the lymph nodes of the patients with TB-IRIS. Conclusions: Neutrophils in TB-IRIS are activated, recruited to sites of disease, and release granule contents, contributing to pathology
