The effect of "universal test and treat" program on HIV treatment outcomes and patient survival among a cohort of adults taking antiretroviral treatment (ART) in low income settings of Gurage zone, South Ethiopia.

BACKGROUND: Through universal "test and treat approach" (UTT) it is believed that HIV new infection and AIDS related death will be reduced at community level and through time HIV can be eliminated. With this assumption the UTT program was implemented since 2016. However, the effect of this program in terms of individual patient survival and treatment outcome was not assessed in relation to the pre-existing defer treatment approach. OBJECTIVE: To assess the effects of UTT program on HIV treatment outcomes and patient survival among a cohort of adult HIV infected patients taking antiretroviral treatment in Gurage zone health facilities. METHODS: Institution based retrospective cohort study was conducted in facilities providing HIV care and treatment. Eight years (2012-2019) HIV/AIDS treatment records were included in the study. Five hundred HIV/AIDS treatment records were randomly selected and reviewed. Data were abstracted using standardized checklist by trained health professionals; then it was cleaned, edited and entered by Epi info version 7 and analyzed by STATA. Cox model was built to estimate survival differences across different study variables. RESULTS: A total of 500 patients were followed for 1632.6 person-year (PY) of observation. The overall incidence density rate (IDR) of death in the cohort was 3 per-100-PY. It was significantly higher for differed treatment program, which is 3.8 per-100-PY compared to 2.4 per-100-PY in UTT program with a p value of 0.001. The relative risk of death among differed cases was 1.58 times higher than the UTT cases. The cumulative probability of survival at the end of 1st, 2nd, 3rd, and 4th years was 98%, 90.2%, 89.2% and 88% respectively with difference between groups. The log rank test and Kaplan-Meier survival curve indicated patients enrolled in the UTT program survived longer than patients enrolled in the differed treatment program (log rank X2 test = 4.1, p value = 0.04). Age, residence, base line CD4 count, program of enrolment, development of new OIS and treatment failure were predicted mortality from HIV infection. CONCLUSION: Mortality was significantly reduced after UTT. Therefore, intervention to further reduce deaths has to focus on early initiation of treatment and strengthening UTT programs.

Therapeutic efficacy of chloroquine for treatment of Plasmodium vivax malaria cases in Guragae zone southern Central Ethiopia.

BACKGROUND: Malaria continues to be a public health problem and important cause of morbidity and mortality in Ethiopia. Due to continuous interventions to combat malaria in endemic regions, a decline in malaria related deaths and morbidity has been registered. These gains, however, are threatened with the emergency of antimalarial drugs resistant strains of plasmodium parasites. This study aimed to determine therapeutic efficacy of chloroquine for treatment of Plasmodium vivax malaria cases in Guragae zone, southern central Ethiopia. METHODS: A one arm prospective study with recurrence of parasitaemia and clinical conditions of patients were evaluated on days 0, 1, 2, 3, 7, 14, and 28. Patients with Plasmodium vivax malaria mono infection and eligible for study inclusion criteria were recruited. SPSS-21 used for data analysis and management. Kaplan-Meier survival probability analysis was estimated. Mean geometric parasitaemia and average haemoglobin concentration were calculated. RESULTS: Among 87 total recruited subjects, 81 of them completed the 28 days follow up. More than half of (57.5%) the study participants had a history of fever and 42.5% of them had fever at the time of enrollment. The mean body temperature on day of recruitment was 38.2 °C and 36.8 °C on day 28. Geometric mean parasitaemia calculated on day of enrollment was 2270 parasites/µl of blood. Recurrence of parasitaemia was registered from two subjects during entire follow up. The mean haemoglobin concentration of study participants on day of enrolment was 11.8 g/ dl and 13.8 g/dl on day 28. CONCLUSION: This study registered a high chloroquine efficacy rate among the study participants. Therefore, chloroquine remains efficacious for the treatment of Plasmodium vivax malaria in the study area. However, there is a need to monitor chloroquine resistance by employing molecular tools for better evaluation of treatment outcome.

Essential in-vitro laboratory diagnostic services provision in accordance with the WHO standards in Guragae zone primary health care unit level, South Ethiopia.

INTRODUCTION: Laboratory services are crucial parts of the health system having a great contribution to disease prevention and management. The importance of accurate and reliable laboratory test results is less recognized in developing countries like Ethiopia where most medical decisions are based on clinical judgment. It is time for countries like Ethiopia to not only increase health care coverage but also improve access to essential diagnostic tests. Hence, this proposed study aims to assess essential in-vitro laboratory service provision in accordance with the WHO standards in Guragae Zone primary health care unit level, South Ethiopia. METHODS: Health institution-based cross-sectional study was carried out. 30% randomly selected primary health care units were recruited. Each facility was visited with a WHO checklist by a trained data collector to assess the availability of essential diagnostics service provision. The proportion of available in-vitro diagnostics services was calculated. Results were presented as percentages in tables and figures. RESULT: Twenty-one primary health care facilities located in Guragae Zone were assessed between May and July 2019. All surveyed facilities had major gaps in essential test availability. Among essential diagnostic tests listed with WHO like C-reactive protein, lipid profile, Amylase and Lipase, TroponinT/I, hepatitis B e-antigen, IgM-specific antibodies to hepatitis B core antigen, Glucose-6-phosphate dehydrogenase activity, and anti-HIV/p24 rapid test were not provided in any facilities. However, essential diagnostic services like urine dipstick testing, random blood sugar, smear microscopy, and few serological tests were provided at all primary health care units. All surveyed facilities had limited major laboratory equipment and consumables. CONCLUSION AND RECOMMENDATION: The present study shows limited access to essential laboratory tests at the primary health care level. Hence, the responsible body should invest to make essential tests accessible at the primary care unit level within the framework of universal health coverage in the study area. The fact that access to essential diagnostic tests is the first key step in improving quality of care; such study has its own efforts to enable the implementation of essential diagnostic lists, and improve access to diagnostics in the country.

Fruit and vegetable contamination with medically important helminths and protozoans in Tarcha town, Dawuro zone, South West Ethiopia.

Background: Fresh vegetables supply the body with essential supplements. The consumption of raw vegetables and fruits are among the ways for transmission of intestinal parasitic organisms to human beings. This study was aimed at detecting the parasitic contamination in fresh vegetables sold at the central open-aired market of Tarcha town, Ethiopia. Methods: A total of 270 fresh vegetables and fruit samples were collected from the main market of Tarcha town during August 1, 2017-August 22, 2017. The samples were microscopically examined for detection of medically important parasites after washing with 500 mL normal saline and 24-hr sedimentation of the washing solution followed by centrifuging at 2000 g for 5 mins. After centrifugation, the supernatant was decanted leaving the sediment. Finally, the sediment was examined under a light microscope for protozoans and helminths worms. Results: Of the 270 fresh vegetable and fruit samples, 115 (42.6%) were found positive for intestinal parasites. A high level of contamination in fresh vegetable and fruit samples was recorded in cabbage 71.1% (32/45) while tomato was the least contaminated 24.4% (11/45). The identified medically important parasites were Entamoeba histolytica/dispar, Giardia intestinalis, Ascaris lumbricoides, Hymenolepis nana, Toxocara spp, Hymenolepis diminuta, and Cystoisospora belli. The most predominant parasite encountered was Ascaris lumbricoides (16.7%) whereas Cystoisospora belli (2.6%) the least detected. All of the vegetables and fruits that were contaminated were with more than one parasite species. A statistically significant association between the type of vegetables and the presence of parasites was also observed (p=0.002). Conclusion: This study has shown that fruits and vegetables which are sold in the study area are highly contaminated with medically important parasites. Fruits and vegetables sold in the study area may play a role in the transmission of intestinal parasitic infections to humans. Effective and comprehensive prevention measures should be taken to ensure food safety. Relevant bodies should work on addressing the issue of high rate of vegetable and fruit contamination in the study area.

Helminth infections in light of an ongoing intervention in endemic areas of Guragae zone, Southern Ethiopia: an implication for neglected tropical diseases elimination in Ethiopia by 2020.

INTRODUCTION: Helminth infections are among the major public health problems in developing countries. Considerable efforts have been made towards the control of morbidity caused by infection with helminths in Ethiopia. The national control program is designed to achieve the elimination of helminth infections as a major public health problem by 2020. OBJECTIVE: The objective of this study was to determine the current status and infection intensity of helminths in the endemic area of Guragae zone, Southern Ethiopia. METHODS: An institutional based cross-sectional study was carried out between April and June 2017 in Gurage zone. School-aged children (SAC) were selected using a multistage sampling method and invited to participate in the study. Parasitological test examination was done using the Kato-Katz technique in Wolkite University parasitology laboratory. SPSS version 21 was used for data management and analysis. RESULTS: A total of 597 (98% compliance rate) participants were able to provide complete data. The study revealed that 21.6% (129/597) SAC were infected with one or more species of helminth. S. mansoni was the most prevalent helminth (12.9%) followed by hookworms (4.3%). The overall infection intensity expressed as geometric mean for A. lumbricoides, T. trichiura, hookworms, and S. mansoni were 301, 31,103, and 158 eggs per gram of stool, respectively. The multivariable logistic regression model estimated that being in the age group of 5-9 years (AOR = 1.43, 95% CI 0.4-0.9), washing raw food and vegetables using river water (AOR = 2.4, 95% CI 0.16-0.75), and a regular bathing habit in river (AOR = 2.14, 95% CI 0.3-0.9) were independent predictors of helminth infections. CONCLUSION: Despite the fact that Ethiopia planned to eliminate helminth infection-related morbidity by 2020, this study showed that helminth infection is prevalent in the study area. Efforts should be made to improve hygienic practices of the schoolchildren in addition to school-based deworming. Moreover, the deworming program should also focus on reaching those SAC who do not attend school through communal social places to achieve the targeted goal in the study area in particular and nationwide in general.

Prevalence, infection intensity and associated factors of soil transmitted helminths among primary school children in Gurage zone, South Central Ethiopia: a cross-sectional study design.

OBJECTIVE: The aim of this study was to determine the prevalence of soil transmitted helminthes among primary school children. School based cross-sectional study design was employed. A total of six hundred study subjects were selected by a multistage sampling method. Fresh stool specimens were collected using clean, dry and wide mouthed labeled stool cups. It was processed by Kato-Katz technique. The data were analyzed using SPSS version 20 and p-value < 0.05 was considered statistically significant. RESULT: The overall prevalence of soil transmitted helminthes was 57 (9.5%). Hookworm was the most prevalent helminthes species isolated (4.2%) followed by A. lumbricoide (3%). The prevalence of Taenia species, T. trichiura, H. nana and E. vermicularis were; 1.2%, 0.5%, 0.7% and 0.8% respectively. The prevalence of the Soil transmitted helminthes infection was low and all cases of Soil transmitted infections in this study were with low infection intensity. This might be due to the preventive chemotherapy given to the school children.

Burden of malaria in Ethiopia, 2000-2016: findings from the Global Health Estimates 2016.

BACKGROUND: Globally malaria remains one of the high burden diseases particularly in developing countries. Ethiopia is one of the sub-Saharan countries highly endemic to malaria. Although, recently the burden of malaria was reduced remarkably through public health interventions designed during the Millennium Development Goals, it is still a major public health problem in Ethiopia. Hence, measuring the burden of the disease and assessing the trend is very important for monitoring the extent and changes over a period of time. OBJECTIVE: This study aimed to assess the burden of malaria in terms of death and Disability-Adjusted Life Years lost (DALY) between 2000 and 2016. METHODS: The research used data from Global Health Estimate 2016; that originally collected the information through vital registration, verbal autopsy, surveys, reports, published scientific articles, Global Burden of Disease study (GBD 2016) and modeling. RESULTS: In 2016 there were an estimated 2,927,266 (95% CI, 525,000-6,983,000) new malaria cases in Ethiopia. It caused an estimated 4,782 deaths (95% CI 122.5-12,750) with a crude death rate of 4.7/100,000 and Age-standardized death rate (ASDR) of 4.9/100,000 population. However, the number of deaths due to malaria declined by 54% from the 2000's record of 10,412 deaths (95% CI 98.8-16180) within 16 years and ASDR declined by 63% from the 2000 record. In the same year, DALY due to malaria was 365,900 years (187,000 years among male and 178,900 years among females). It contributed for 0.78% of the total DALY in Ethiopia and 1% of the global DALY due to malaria. Around 332,100 life years (YLL) were lost and 35,200 years were lived with disability (YLD) due to malaria. Mortality and DALY related to malaria is slightly higher among males; and under 5 children are highly affected. CONCLUSION AND RECOMMENDATION: Although, the burden of malaria is remarkably declining in Ethiopia; with a higher level of mortality and DALY, it still remained one of the public health problems. Therefore, strengthening the existing malaria prevention program is important to eliminate the disease within the target period.

Impact of annual preventive mass chemotherapy for soil-transmitted helminths among primary school children in an endemic area of Gurage zone: a prospective cross-sectional study.

BACKGROUND AND AIM: School-based preventive mass chemotherapy has been a key component of Ethiopia's national plan for the control of soil-transmitted helminths. Without an impact evaluation on the impact of a deworming program on infection levels, it is unclear whether the deworming program warrants levels of environmental transmission of infection. This study aimed to determine the impact of annual preventive mass chemotherapy for soil-transmitted helminths among schoolchildren in an endemic area of Gurage zone, south-central Ethiopia. METHODS: A repeated school-based quantitative prospective cross-sectional method was employed. Data were collected from study participants selected using systematic sampling with probability proportional to size at baseline and after annual treatment. Fresh stool samples were collected and processed using the Kato─Katz technique at the Wolkite University parasitology laboratory. SPSS-21 was used for data management and analysis. Changes in parasitological variables after treatment were estimated. RESULTS: Overall, 41.1% prevalence and 22.3% mean geometric infection-intensity reduction were found. Reductions in prevalence of Schistosoma mansoni and hookworms were 13.2% and 15.3%, respectively. Similarly, decreases in prevalence were seen in Ascaris lumbricoides and Trichuris trichiura, representing 94.4% and 80.0% reduction rates, respectively, while 25.9% of the children had heavy S. mansoni (≥400 eggs per gram) infections at baseline, which were reduced to 4.5% after annual treatment. Geometric mean infection intensity-reduction rates for hookworms, A. lumbricoides, and T. trichiura were 80.8%, 20.2%, and 96.7%, respectively. CONCLUSION: Annual mass chemotherapy failed to clear soil-transmitted helminths completely in the present study. However, it resulted in a substantial reduction in overall prevalence and infection intensity. Therefore, other than deworming for school children, interventions such as access to improved personal hygiene and environmental hygiene in school should be emphasized to interrupt transmission.

Gender disparity in epidemiological trend of HIV/AIDS infection and treatment in Ethiopia.

BACKGROUND: The HIV/AIDS epidemic has been fuelled by gender inequality and disparity resulted in violation of women reproductive right. The "feminization" of the pandemic is more apparent in Sub-Saharan Africa where the larger numbers of HIV infected people are living. Although they carry the higher proportion of HIV cases; access to care and treatment is lower among women. In Ethiopia where HIV is prevalent and gender violence is common, the disparity may be higher. Therefore, this research aimed to assesses trends in gender disparity in the HIV/AIDS epidemic in Ethiopia to bring evidence for action. METHODS: This study was conducted using aggregates of HIV/AIDS indicator data from 1990 to 2016 of UNAIDS data bases. The data was compiled and analyzed with excel and STATA Version 11. The trend was assessed, gender difference was measured and rate of change was compared between genders and specific age groups. RESULT: Adult females (age 15+) accounted 61.5% of the HIV cases and new infection among adults. While, adolescent females (age 10-19) and young women (age 15-24) accounted 52.3 and 57.5% of prevalent cases and 74 and 68% of new infection in their age category respectively. HIV is 1.62 times more prevalent among adult women than men. Since 1990, HIV cases among adults has risen markedly in the first decade with 24 and 20%, then declined by 41.5% in the second decade and rose again by 5 and 8.7% among women and men respectively. The overall prevalence is declined by 72.4 and 71.5% from the maximum record. Women and men have equal access for ART; 62% of men and 61% of women from all adults living with HIV were on ART. While 61% of deaths were among adult women and the death rate is similar among adolescent women and men. AIDS- related death has been declined by 76% from the maximum record. CONCLUSION: HIV/AIDS prevalence, new infection and AIDS-related death are by far higher among adult women than men. While the coverage of treatment and HIV care is equal among both genders. Vulnerable age groups (adolescent females and young women) take the lion's share of the new infections and prevalent cases. Therefore due attention is needed to avert gender disparity with a particular emphasis for adolescents and young women.

Soil-Transmitted Helminths and Associated Factors among Pre-School Children in Butajira Town, South-Central Ethiopia: A Community-Based Cross-Sectional Study.

BACKGROUND: Soil-transmitted helminths (STH) remain a major public health problem, particularly in tropical and sub-tropical regions of the world. Though infections are prevalent among all age groups, the world health organization (WHO) considers Pre-school age children (PSAC), school-aged children, and pregnant women as segments of population at high risk of STH morbidities. OBJECTIVE: This study aimed at determining the prevalence and infection intensity of STH and associated factors among PSAC in Butajira Town, south-central Ethiopia. METHODS: A community-based cross-sectional study was conducted from May to June, 2014 in Butajira Town. The PSAC were selected by systematic sampling technique and invited to participate in the present study. McMaster technique was employed for parasitological analysis of stool samples. Pearson's Chi-square and Fisher's exact tests were performed where appropriate to identify any association between STH infection and independent factors. Multivariate logistic regression model was fitted to identify independent predictors of STH among the PSAC. P-value less than 0.05 was considered statistically significant. RESULTS: A total of 377 (with 96% compliance rate) PSAC were able to provide complete data (socio-demographic information and stool sample). The study showed that 23.3% (88/377) PSAC were infected with one or more species of STH. Ascaris lumbricoides was the most prevalent STH (14.9%) followed by Trichuris trichiura (6.4%). The overall infection intensity, expressed as geometric mean for A. lumbricoides, T. trichiura, and hookworms were 229, 178, and 154 eggs per gram of stool, respectively. The multivariate logistic regression model estimated that being in the age group of 36-47 months (AOR: 2.5, 95% CI: 1.2-5.3, P = 0.016), untrimmed finger nail (AOR: 3.2, 95% CI: 1.8-5.5, P < 0.001), and not washing hands before a meal (AOR: 3.0, 95% CI: 1.7-5.4, P < 0.001) were independent predictors of STH infections among the children. CONCLUSION: The present study showed that STH was a public health problem among PSAC in the study area necessitating annual deworming to control morbidities associated with STH. Besides, the existing health education program should also be strengthened to prevent re-infection.
