  Background: Tuberculosis disease affects survival among HIV co-infected patients on antiretroviral therapy. Prevalence of pulmonary tuberculosis in western Uganda is 15.3% and 7.2% in Tororo, Eastern Uganda. A study in Kampala revealed Tuberculosis prevalence among immuno-incompetent group at 10%. To assess the prevalence of Pulmonary Tuberculosis (PTB) infection in HIV/AIDS patients attending ART clinic in Bududa general hospital, Bududa district, a hospital-based, cross-sectional study was carried out. 
  Methods and materials: Two hundred thirty eight (238) HIV/AIDS positive patients attending ART clinic were recruited using consecutive simple non-probability sampling on consenting. Data collection guide was used to capture the socio-demographic information from study participants and two sputum samples (spot and early morning samples) were obtained from each participant, and processed using Hot Ziehl Neelsen for Tubercle Bacilli. Data collected was entered into MS Excel spreadsheets and Statistical Package of Social Sciences was used for descriptive data analysis and outputs in form of percentages, figures and tables presented. 
  Results: Out of 238 study participants recruited, 14/238 were positive for Acid Fast Bacilli (AFB); giving a prevalence of pulmonary tuberculosis at 5.9% (14/238) and the most affected age group was between 26 - 35 years with the prevalence of 3.4%. More females (65.6%) participated in the study than males (34.4%). 
  Conclusion: Tuberculosis remains a health challenge in HIV/AIDS positive people in Bududa district and there is need for early screening of all HIV patients for TB as part of their routine and intensification to follow up TB positive patients. We recommend large-scale studies on the trends in TB/HIV co-infection and associated factors should be carried out in this area. In addition, we recommend intensification of public awareness campaign about TB infection in relation to its transmission, prevention and control.

Introduction</title><p>Tuberculosis disease affects survival among HIV co-infected patients on antiretroviral therapy. The risk of developing tuberculosis is estimated to be between 16 - 27 times greater in people living with HIV than among those without HIV infection. In Uganda, with national HIV prevalence of 7.3%, 45,546 TB patients were diagnosed in the year 2010 of which 54% were HIV-infected [<xref ref-type="bibr" rid="scirp.94930-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.94930-ref2">2</xref>].</p><p>Uganda is one of the high burden twenty two countries in Sub-Sahara Africa that contributes 80% of the world’s tuberculosis burden [<xref ref-type="bibr" rid="scirp.94930-ref3">3</xref>].

Accurate estimates of prevalence are important for public policy and planning to prevent disease spread yet, the magnitude of TB disease on mortality is poorly understood in Bududa Hospital.

Discussions</title>Prevalence of Pulmonary Tuberculosis<p>The objective of this study was to determine the prevalence of Pulmonary Tuberculosis among adult HIV-positive patients receiving ART services from ART Clinic at Bududa Hospital.</p><p>Pulmonary complications have been one of the commonest causes of morbidity and mortality since the advent of AIDS (Acquired Immune Deficiency Syndrome) pandemic. According to an estimate of World Health Organization, TB has become one of the leading causes of death among HIV-infected persons. In Uganda, with national HIV prevalence of 7.3%, 45,546 TB patients were diagnosed in the year 2010 of which 54% were HIV-infected [<xref ref-type="bibr" rid="scirp.94930-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.94930-ref2">2</xref>]. From this study, the prevalence of pulmonary tuberculosis in HIV/AIDs patients was 5.9% (14/238). People living with HIV are most vulnerable to contracting active TB because of the deficiency of immune response. This study finding showed a lower prevalence compared to global prevalence at 11%. Similar trends have been observed in different settings in Uganda by many authors [<xref ref-type="bibr" rid="scirp.94930-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.94930-ref6">6</xref>] [<xref ref-type="bibr" rid="scirp.94930-ref7">7</xref>]. These could be explained by the fact that unlike in this study, different approaches were used for TB diagnosis that increased sensitivity hence detecting more positive cases and could also be associated to the control interventions in the area.</p><p>The study findings are not in line with the findings from a related study that showed that 17% of HIV infected persons had tuberculosis co-infection [<xref ref-type="bibr" rid="scirp.94930-ref10">10</xref>]. The difference could be attributed to several diagnostic methods employed like use of chest X-ray, and microscopic examination of sputum for acid fast bacillus hence increasing sensitivity compared to our study that used only smear microscopy affecting sensitivity so we might have missed some cases of tuberculosis hence a lower prevalence.</p><p>Despite the low prevalence of HIV-TB co-infection revealed by this study, Tuberculosis attributes to a six-fold to seven-fold increase of viral load in HIV positive population [<xref ref-type="bibr" rid="scirp.94930-ref11">11</xref>] where the infection induces cytokines that enhance the replication of HIV and this drives the patient into full picture of AIDS [<xref ref-type="bibr" rid="scirp.94930-ref12">12</xref>].</p><p>This study had 238 participants in which females were more than males with 65.6% and 34.4% respectively. The higher number of female participants could have been due to their pronounced health seeking behaviors than males [<xref ref-type="bibr" rid="scirp.94930-ref13">13</xref>].</p><p>The prevalence of pulmonary tuberculosis (PTB) based on gender was 4.2% and 1.61% in females and males respectively. The gender-related prevalence of PTB observed in this study had a similar trend to findings obtained in similar studies [<xref ref-type="bibr" rid="scirp.94930-ref13">13</xref>] [<xref ref-type="bibr" rid="scirp.94930-ref14">14</xref>] [<xref ref-type="bibr" rid="scirp.94930-ref15">15</xref>].</p><p>The age-related prevalence was high among participants who were between 26 - 35 age group constituting a prevalence of 8/238 (3.4%). The high prevalence in the age group of 26 - 35 could be attributed to their increased social behaviors like being socially active and attractive to the peers from whom the infections acquired and transmitted. smoking, stress due to poverty and alcoholism predispose this age group to high chances of acquiring the disease [<xref ref-type="bibr" rid="scirp.94930-ref16">16</xref>] , The positive cases in 46-above age group could be due to their social behaviors like sharing drinking tubes for local brewed alcohol like “malwa” from which infected cases/people infect others, smoking, and consumption of insufficiently boiled milk, poor nutrition status.</p><p>These study findings provide the current knowledge about the burden of tuberculosis in HIV/AIDS positive living thus creating awareness to health Authorities and policy makers about the infection dangers and is expected to lead to improved efforts in controlling and eradicating of pulmonary tuberculosis among HIV/AID’s patients and their community.</p><p>All HIV-infected individuals should be tested for tuberculosis prior to the initiation of ART and while on ART in places where this disease is Endemic; where several tests including Gene Xpert, chest X-ray and sputum hot ZN and cultures should be carried out routinely to aid in early detection and treatment to reduce the spread of the disease.</p></sec><sec id="s5"><title>5. Conclusion</title><p>Tuberculosis remains a health challenge in HIV/AIDS positive people in Bududa district and there is need for early screening of all HIV patients for TB as part of their routine and intensification to follow up TB positive patients.</p></sec><sec id="s6"><title>6. Recommendations</title><p>These findings suggest that strategies for early HIV diagnosis to increase timely diagnosis of HIV before it is adversely advanced could potentially reduce the occurrence of Tuberculosis in this setting.</p><p>In addition, we recommend intensification of public awareness campaign about TB infection in relation to its transmission and prevention, control and treatment.</p></sec><sec id="s7"><title>Acknowledgements</title><p>I acknowledge Mzee Mutanje Solomon Masudi and the family for the parental, financial and social support.
