The interaction between diabetes and major world infections like TB is a major public health concern because of rapidly rising levels of diabetes. The dual burden of tuberculosis (TB) and diabetes mellitus (DM) has become a major global public health problem. Diabetes mellitus is a major risk factor for the development of active and latent tuberculosis. Immune mechanisms contributing to the increased susceptibility of diabetic patients toTBare due to the defects in bacterial recognition, phagocytic activity, and cellular activation which results in impaired production of chemokines and cytokines. The initiation of adaptive immunity is delayed by impaired antigen-presenting cell (APC) recruitment and function in hyperglycemic host, which results in reduced frequencies of Th1, Th2, and Th17 cells and its secretion of cytokines having a great role in activation of macrophage and inflammatory response of tuberculosis. In addition, impaired immune response and killing of intracellular bacteria potentially increase bacterial load, chronic inflammation, and central necrosis that facilitate bacterial dissemination and miliary tuberculosis. Understanding of the immunological and biochemical basis ofTBsusceptibility in diabetic patients will tell us the rational development of implementation and therapeutic strategies to alleviate the dual burden of the diseases. Therefore, the aim of this review was focused on the association between diabetes and tuberculosis, focusing on epidemiology, pathogenesis, and immune dysfunction in diabetes mellitus, and its association with susceptibility, severity, and treatment outcome failure to tuberculosis.
Background: Hospital-acquired infections can be acquired by a patient or develop among hospital staff, as a more serious problem in low- and middle-income hospital settings. Assessing the level of knowledge, attitude and practice towards hospital-acquired infection prevention among healthcare workers and identifying the associated factors has an unquestionable importance of handling and management of these infections. Thus, in this study, we evaluated the knowledge, attitude and practice towards HAIs prevention and associated factors in healthcare workers at the University of Gondar Comprehensive Specialized Hospital, North West Ethiopia. Methods: Hospital-based cross-sectional study was conducted among healthcare workers towards HAIs prevention from January to June 2019. Each study participant was selected by simple random sampling. Data were collected using structured self-administered questionnaires. Descriptive analysis was used to present frequency and percentage of the main findings. The association between independent variables and KAP scores on HAI prevention was calculated using Pearson’s Chi square and p-values less than 0.05 were considered as statistically significant. Results: A total of 236 participants were included in this study with a 100% response rate; 90% and 57.2% of the participants had good knowledge and positive attitude towards HAI prevention, respectively. Meanwhile, only 36% of the study participants had good practice towards HAI prevention, suggesting less than satisfactory scores in this study. Level of education and work experience were significantly associated with safe-infection prevention attitude and practice (P value < 0.005). Conclusion: Even though the respondents have good knowledge with a sympathetic attitude about HAI preventions, good knowledge did not translate into prudent practices. Level of education and work experience were the independent risk factors towards HAI prevention of attitude and practice. Provision of continual on-job and off-job trainings together with strict implementation of updated standard operational procedures (SOP) may reduce the identified gap.
Background: Tuberculosis (TB) and HV have been intertwined and makeup a deadly human syndemic worldwide, especially in developing countries like Ethiopia. Previous studies have reported different TB incidences and its association with CD4+ T cell counts among HIV positive patients in Ethiopia. Thus, the goal of this meta-analysis was, first, to determine pooled incident TB among adult HIV positive patients, and second, to assess the association between incident TB and baseline CD4+ T cell count strata’s. Methods: We searched PubMed, Cochrane library, Science Direct and Google scholar databases from June 1 to 30, 2018. The I2 statistics and Egger’s regression test was used to determine heterogeneity and publication bias among included studies respectively. A random effects model was used to estimate pooled incident TB and odds ratio with the respective 95% confidence intervals using Stata version 11.0 statistical software. Results: A total of 403 research articles were identified, and 10 studies were included in the meta-analysis. The pooled incident TB among adult HIV infected patients in Ethiopia was 16.58% (95% CI; 13.25–19.91%). Specifically, TB incidence in Pre-ART and ART was 17.16% (95% CI; 7.95–26.37%) and 16.24% (95% CI; 12.63–19.84%) respectively. Moreover, incident TB among ART receiving patients with baseline CD4+ T cell count < and > 200 cells/mm3 was 28.86% (95% CI; 18.73–38.98%) and 13.7% (95% CI; 1.41–25.98%) correspondingly. The odds of getting incident TB was 2.88 (95% CI; 1.55–5.35%) for patients with baseline CD4+ T cell count < 200 cells/mm3 compared to patients with baseline CD4+ T cell count > 200 cells/mm3. Conclusion: High incident TB among adult HIV positive patients was estimated, especially in patients with CD4+ T cell count < 200 cells/mm3. Therefore, Early HIV screening and ART initiation, as well as strict compliance with ART and increasing the coverage of TB preventive therapy to more risky groups are important to prevent the problem.

Background. Hepatitis B virus (HBV) infection remains a serious public health concern worldwide. Mother-to-child transmission (MTCT) is the major mode in endemic areas, including Ethiopia, where little is known about pregnant women’s knowledge, attitudes, and practice towards HBV infection and MTCT. Therefore, the study is aimed at determining the knowledge, attitude, and practice towards HBV among pregnant women attending antenatal care. Method. A cross-sectional study was conducted from February to April 2018, at the University of Gondar Comprehensive Specialized Hospital. A total of 354 pregnant women were selected by systematic random sampling and included in this study. KAP of participants on HBV MTCT was assessed using a structured questionnaire. Data was analyzed using SPSS version 22 software. Result. The total response rate was 100% (354/354). Out of the 354 participants, 73.4% were within the poor knowledge. Only 18.9% of the respondents know HBV can be transmitted from mother to child during pregnancy. Less than half (43.8) of the participants think that they will never be infected with HBV, and 47.7% of them go to traditional healers when they have symptoms of HBV. Majority of the respondents (85.87%) had never screened for HBV, and only 28.5% of the participants believed that hepatitis B can cause liver cancer. In multivariable analysis, residence, income, and educational level were associated with mean score knowledge and attitude. Conclusions. Knowledge about HBV among pregnant women was found to be poor, and their attitude and practice were also limited. Therefore, extensive health education program should be given to the pregnant women to increase their awareness towards HBV infection. All pregnant women should be screened for HBV as part of ANC follow-up.
Despite the undeniable significance of blood transfusion in saving a millions life in emergencies and medical treatment, the quality of blood faced challenges from transfusion-transmitted infections (TTIs) such as HIV (human immunodeficiency virus), HBV (hepatitis B virus) and HCV (hepatitis C virus). This cross-sectional study was undertaken with the aim of determining the seroprevalence and risk factors of HIV, HBV, and HCV among blood donors. An institutional based cross-sectional study was conducted at Debre Tabor district hospital from January 2017 to February 2018. Blood samples from volunteer donors collected; serum separated and screened with ELISA tests for detection of anti-HIV, hepatitis-B surface antigen (HBsAg) and anti-HCV. Fishers’ exact test was employed to see the association between variables as well logistic regression tests were applied to identify potential risk factors. P-value of less than 0.05 was considered as statistically significant. A total of 310 volunteer donors were included in the study. The proportion of blood donors having at least one viral-TTI was 12.6% while the magnitudes of HIV, HBV, and HCV were 2.6, 5.8 and 4.2%, respectively. Educational status and multiple sexual behaviors are significantly associated with HIV acquisition whilst marital status was significantly associated with HBsAg seropositivity. Seroprevalence of transfusion-transmissible infections was high and alarming therefore proper screening of donated blood with test methods having better diagnostic performance should be employed. Also encouragement of blood donation from voluntary donors and creating awareness on the general public regarding HIV, HBsAg and HCV transmission and prevention should be strengthen.
Tuberculosis (TB) and HIV makeup a deadly synergy of infectious disease, and the combined effect is apparent in resource limited countries like Ethiopia. Previous studies have demonstrated inconsistent results about the protective effect of isoniazid preventive therapy (IPT) on active TB incidence among HIV positive patients receiving ART. Therefore, the aim of this meta-analysis was, first, to determine the protective effect of IPT on active tuberculosis incidence, and second, to assess the pooled incidence of active TB among HIV positive patients taking ART with and without IPT intervention in Ethiopia. PubMed, Google scholar and Cochran library databases were searched from April 1 to 30, 2018. Two independent authors explored and assessed studies for eligibility, and extracted data based on predefined criteria. Studies that reported TB incidence among HIV positive patients taking ART in Ethiopia with and without IPT concomitant intervention, and with a clear stratified data on the incidence of TB based on the duration of IPT intervention were selected. A random effects model was used to estimate risk ratios and the pooled incident TB with the respective 95% confidence intervals. We identified 7 suitable studies in this analysis. Accordingly, IPT reduced the risk of TB incidence by 74%, risk ratio (RR) 0.26 (95% CI; 0.16–0.43%), compared to no IPT group. Moreover, IPT for 12 months reduced incident TB by 91% (RR: 0.09, 95% CI: 0.04 to 0.21), whereas 6 months IPT averted TB incidence by 63% (RR: 0.37, 95% CI: 0.26 to 0.52). The overall pooled incident TB among HIV infected patients receiving ART was 10.30% (95% CI; 7.57–13.02%). Specifically, incident TB among study cohorts with and without IPT was 3.79% (95% CI; 2.03–5.55%) and 16.32% (95% CI; 11.57–21.06%) respectively. IPT reduced the risk of incident TB among HIV positive patients receiving ART in Ethiopian settings. Moreover, the duration of IPT intervention has effect on its protective role. Thus, scaling up the isoniazid preventive therapy program and its strict compliance is necessary to avert HIV fueled tuberculosis. CRD42018090804.
