Burden of malaria among adult patients attending general medical outpatient department and HIV care and treatment clinics in Oromia, Ethiopia: a comparative cross-sectional study
Background
Malaria and HIV/AIDS constitute major public health problems in Ethiopia, but the burden associated with malaria-HIV co-infection has not been well documented. In this study, the burden of malaria among HIV positive and HIV negative adult outpatients attending health facilities in Oromia National Regional State, Ethiopia was investigated.
Methods
A comparative cross-sectional study among HIV-positive patients having routine follow-up visits at HIV care and treatment clinics and HIV-seronegative patients attending the general medical outpatient departments in 12 health facilities during the peak malaria transmission season was conducted from September to November, 2011. A total of 3638 patients (1819 from each group) were enrolled in the study. Provider initiated testing and counseling of HIV was performed for 1831 medical outpatients out of whom 1819 were negative and enrolled into the study. Malaria blood microscopy and hemoglobin testing were performed for all 3638 patients. Data was analyzed using descriptive statistics, Chi square test and multivariate logistic regression.
Results
Of the 3638 patients enrolled in the study, malaria parasitaemia was detected in 156 (4.3 %); malaria parasitaemia prevalence was 0.7 % (13/1819) among HIV-seropositive patients and 7.9 % (143/1819) among HIV-seronegative patients. Among HIV-seropositive individuals 65.4 % slept under a mosquito bed net the night before data collection, compared to 59.4 % of HIV-seronegative individuals. A significantly higher proportion of HIV-seropositive malaria-negative patients were on co-trimoxazole (CTX) prophylaxis as compared to HIV-malaria co-infected patients: 82 % (1481/1806) versus 46 % (6/13) (P = 0.001). HIV and malaria co-infected patients were less likely to have the classical symptoms of malaria (fever, chills and headache) compared to the HIV-seronegative and malaria positive counterparts. Multivariate logistic regression showed that HIV-seropositive patients who come for routine follow up were less likely to be infected by malaria (OR = 0.23, 95 % CI = 0.09–0.74).
Conclusion
The study documented lower malaria prevalence among the HIV-seropositive attendants who come for routine follow up. Clinical symptoms of malaria were more pronounced among HIV-seronegative than HIV-seropositive patients. This study also re-affirmed the importance of co-trimoxazole in preventing malaria symptoms and parasitaemia among HIV- positive patients
Prevalence and correlates of physical violence and rape among female sex workers in Ethiopia : a cross-sectional study with respondent-driven sampling from 11 major towns
OBJECTIVE: This study examined the prevalence and correlates of physical violence and rape among female sex workers (FSWs) in Ethiopia.DESIGN: A cross-sectional study using respondent-driven sampling technique.SETTING: Eleven major towns in Ethiopia.PARTICIPANTS: 4900 FSWs.MAIN OUTCOME MEASURES: The prevalence of experiences of physical beating and rape.RESULTS: Among FSWs, 17.5% reported physical beating within the last year and 15.2% reported rape since they started selling sex. FSWs aged 35+ years (AOR 0.59, 95% CI 0.38 to 0.92) were less exposed to physical beating than those aged 15-24 years. FSWs working on the street (AOR 1.92, 95% CI 1.53 to 2.39), in red-light houses (AOR 1.63, 95% CI 1.12 to 2.38) and in local drinking houses (AOR 1.35, 95% CI 1.02 to 1.78) experienced more physical beating than FSWs working in bars/hotels. FSWs who consumed alcohol four or more days in a week (AOR 1.92, 95% CI 1.21 to 3.04), and who chewed khat frequently experienced more physical violence. Rape was associated with having a low monthly income, drinking alcohol four or more days per week (AOR 2.33, 95% CI 1.47 to 3.7), experience of heavy episodic drinking in a month (AOR 1.71, 95% CI 1.24 to 2.38) and chewing khat 3-4 days per week (AOR 2.15, 95% CI 1.55 to 2.98). Condom breakage was more frequent among FSWs who reported both physical beating (AOR 1.51, 95% CI 1.25 to 1.84) and rape (AOR 1.26, 95% CI 1.03 to 1.55).CONCLUSION: FSWs in Ethiopia are vulnerable to physical and sexual violence, and the risk increases when they are younger, street-based and high consumers of alcohol or khat. Therefore, targeted efforts are needed for prevention and harm reduction
Growth pattern in Ethiopian infants – the impact of exposure to maternal HIV infection in relation to socio-economic factors
Background: Infants exposed to maternal HIV infection who remain HIV-uninfected (HIV-exposed/uninfected; HIV-EU) may be at increased risk of growth retardation, which could be due both to directly HIV-related effects and to socio-economic factors overrepresented among HIV-positive women. Objective: To investigate growth development at 9–12 months of age in HIV-EU infants participating in prevention of mother-to-child transmission (PMTCT) care compared to HIV unexposed (HIV-U) infants in relation to socio-economic conditions. Methods: Anthropometric and socio-economic data were collected retrospectively from PMTCT registers (for HIV-EU infants), with HIV-U controls recruited at measles vaccination at public health facilities in Ethiopia. Growth was compared with regard to HIV exposure and socio-economic variables in multivariate regression analysis. Results: The following growth measurements were found for 302 HIV-EU and 358 HIV-U infants at 9–12 months of age, respectively: mean weight-for-age z-score (WAZ) 0.04 and −0.21, p < 0.001 (proportion underweight 5.7% and 6.7%, p = 0.60); median length-for-age z-score (LAZ) −0.92 and −0.91, p = 0.53 (proportion stunted 25.1% and 20.5%, p = 0.17). In multivariate analysis, lower WAZ was associated with male sex (p = 0.021), lower maternal education (p < 0.001), presence of siblings (p < 0.01) and HIV-U (p < 0.01). Underweight was associated with male sex (p = 0.017) and absence of maternal education (p = 0.019). Lower LAZ was associated with male sex (p < 0.001), presence of siblings (p < 0.001) and poor maternal education (p < 0.01), while stunting was associated with male sex (p < 0.001), presence of siblings (p < 0.001), few rooms in the home (p < 0.01), access to running water (p = 0.026) and low level of maternal education (p = 0.014). Conclusions: At 9–12 months of age, HIV-EU infants had non-inferior growth and higher mean WAZ than HIV-U controls. Poor growth development was associated with socio-economic factors. This suggests health benefits from PMTCT participation for infant growth. Similar interventions could be considered for Ethiopian infants, irrespective of HIV exposure, with a particular focus on children with poor socio-economic status
Long-term Outcome of Antiretroviral Treatment in Patients With and Without Concomitant Tuberculosis Receiving Health Center-Based Care-Results From a Prospective Cohort Study
Background: In order to increase treatment coverage, antiretroviral treatment (ART) is provided through primary health care in low-income high-burden countries, where tuberculosis (TB) co-infection is common. We investigated the long-term outcome of health center-based ART, with regard to concomitant TB.Methods: ART-naïve adults were included in a prospective cohort at Ethiopian health centers and followed for up to 4 years after starting ART. All participants were investigated for active TB at inclusion. The primary study outcomes were the impact of concomitant TB on all-cause mortality, loss to follow-up (LTFU), and lack of virological suppression (VS). Kaplan-Meier survival estimates and Cox proportional hazards models with multivariate adjustments were used.Results: In total, 141/729 (19%) subjects had concomitant TB, 85% with bacteriological confirmation (median CD4 count TB, 169 cells/mm3; IQR, 99-265; non-TB, 194 cells/mm3; IQR, 122-275). During follow-up (median, 2.5 years), 60 (8%) died and 58 (8%) were LTFU. After ≥6 months of ART, 131/630 (21%) had lack of VS. Concomitant TB did not influence the rates of death, LTFU, or VS. Male gender and malnutrition were associated with higher risk of adverse outcomes. Regardless of TB co-infection status, even after 3 years of ART, two-thirds of participants had CD4 counts below 500 cells/mm3.Conclusions: Concomitant TB did not impact treatment outcomes in adults investigated for active TB before starting ART at Ethiopian health centers. However, one-third of patients had unsatisfactory long-term treatment outcomes and immunologic recovery was slow, illustrating the need for new interventions to optimize ART programs
Tuberculosis screening among ambulatory people living with HIV: a systematic review and individual participant data meta-analysis
Background: The WHO-recommended tuberculosis screening and diagnostic algorithm in ambulatory people living with HIV is a four-symptom screen (known as the WHO-recommended four symptom screen [W4SS]) followed by a WHO-recommended molecular rapid diagnostic test (eg Xpert MTB/RIF [hereafter referred to as Xpert]) if W4SS is positive. To inform updated WHO guidelines, we aimed to assess the diagnostic accuracy of alternative screening tests and strategies for tuberculosis in this population. Methods: In this systematic review and individual participant data meta-analysis, we updated a search of PubMed (MEDLINE), Embase, the Cochrane Library, and conference abstracts for publications from Jan 1, 2011, to March 12, 2018, done in a previous systematic review to include the period up to Aug 2, 2019. We screened the reference lists of identified pieces and contacted experts in the field. We included prospective cross-sectional, observational studies and randomised trials among adult and adolescent (age ≥10 years) ambulatory people living with HIV, irrespective of signs and symptoms of tuberculosis. We extracted study-level data using a standardised data extraction form, and we requested individual participant data from study authors. We aimed to compare the W4SS with alternative screening tests and strategies and the WHO-recommended algorithm (ie, W4SS followed by Xpert) with Xpert for all in terms of diagnostic accuracy (sensitivity and specificity), overall and in key subgroups (eg, by antiretroviral therapy [ART] status). The reference standard was culture. This study is registered with PROSPERO, CRD42020155895. Findings: We identified 25 studies, and obtained data from 22 studies (including 15 666 participants; 4347 [27·7%] of 15 663 participants with data were on ART). W4SS sensitivity was 82% (95% CI 72–89) and specificity was 42% (29–57). C-reactive protein (≥10 mg/L) had similar sensitivity to (77% [61–88]), but higher specificity (74% [61–83]; n=3571) than, W4SS. Cough (lasting ≥2 weeks), haemoglobin (<10 g/dL), body-mass index (<18·5 kg/m2), and lymphadenopathy had high specificities (80–90%) but low sensitivities (29–43%). The WHO-recommended algorithm had a sensitivity of 58% (50–66) and a specificity of 99% (98–100); Xpert for all had a sensitivity of 68% (57–76) and a specificity of 99% (98–99). In the one study that assessed both, the sensitivity of sputum Xpert Ultra was higher than sputum Xpert (73% [62–81] vs 57% [47–67]) and specificities were similar (98% [96–98] vs 99% [98–100]). Among outpatients on ART (4309 [99·1%] of 4347 people on ART), W4SS sensitivity was 53% (35–71) and specificity was 71% (51–85). In this population, a parallel strategy (two tests done at the same time) of W4SS with any chest x-ray abnormality had higher sensitivity (89% [70–97]) and lower specificity (33% [17–54]; n=2670) than W4SS alone; at a tuberculosis prevalence of 5%, this strategy would require 379 more rapid diagnostic tests per 1000 people living with HIV than W4SS but detect 18 more tuberculosis cases. Among outpatients not on ART (11 160 [71·8%] of 15 541 outpatients), W4SS sensitivity was 85% (76–91) and specificity was 37% (25–51). C-reactive protein (≥10 mg/L) alone had a similar sensitivity to (83% [79–86]), but higher specificity (67% [60–73]; n=3187) than, W4SS and a sequential strategy (both test positive) of W4SS then C-reactive protein (≥5 mg/L) had a similar sensitivity to (84% [75–90]), but higher specificity than (64% [57–71]; n=3187), W4SS alone; at 10% tuberculosis prevalence, these strategies would require 272 and 244 fewer rapid diagnostic tests per 1000 people living with HIV than W4SS but miss two and one more tuberculosis cases, respectively. Interpretation: C-reactive protein reduces the need for further rapid diagnostic tests without compromising sensitivity and has been included in the updated WHO tuberculosis screening guidelines. However, C-reactive protein data were scarce for outpatients on ART, necessitating future research regarding the utility of C-reactive protein in this group. Chest x-ray can be useful in outpatients on ART when combined with W4SS. The WHO-recommended algorithm has suboptimal sensitivity; Xpert for all offers slight sensitivity gains and would have major resource implications.

Complementary Feeding Habits in Children Under the Age of 2 Years Living in the City of Adama in the Oromia Region in Central Ethiopia : Traditional Ethiopian Food Study
Updated information on child feeding practices, nutritional status, and trends related to parental sociodemographic variables is required in developing countries. The objective of this study was to describe infant feeding practices and associated sociodemographic factors among Ethiopian children with an emphasis on complementary feeding (CF). Information on infant feeding and anthropometric measures was obtained from 1,054 mother-child pairs participating in a birth cohort study of children born between 2017 and 2020 prospectively followed in the city of Adama located in the Oromia region of central Ethiopia. Logistic regression models were used to identify sociodemographic and food groups associated with the initiation of CF. The introduction of complementary foods at 6 months of age was 84.7% (95% CI, 82.5, 86.8). Vegetables, cereals (teff, wheat, barley), and fruits were most often the earliest types of foods introduced. Wasting, stunting, underweight, and low body mass index (BMI) by age were found in 6.0, 16.9, 2.5, and 6.3%, respectively. Maternal age and occupation were the factors associated with timely initiation of CF [OR = 2.25, (95% CI, 1.14, 4.41)] and [OR = 0.68, (95% CI, 0.48, 0.97)], respectively. This study demonstrates that the majority of Ethiopian children in the Oromia region follow the recommendations of WHO on CF
Brief Report : Interferon-γ-Inducible Protein 10-A Potential Marker for Targeted Viral Load Monitoring of Antiretroviral Treatment?
BACKGROUND: The use of surrogate markers for targeting viral load (VL) testing could be an alternative to universal VL testing during antiretroviral treatment (ART) and would allow for more effective resource allocation. We investigated the correlation between levels of HIV RNA and interferon-γ-inducible protein 10 (IP-10) in Ethiopian adults at 12 months after ART initiation. In addition, we specifically investigated differences in IP-10 levels between patients with and without virological suppression.SETTING: Cohort of HIV-positive adults receiving ART at Ethiopian health centers.METHODS: Using a nested case-control design, individuals without virological suppression (HIV RNA ≥ 150 copies/mL) at 12 months after ART initiation were gender-matched with virologically suppressed controls (1:2 ratio). IP-10 levels were correlated with HIV RNA, and the distribution of IP-10 was compared for 3 VL strata: <150 copies/mL (VL < 150), 150-999 copies/mL (VL150-999), and ≥1000 copies/mL (VL ≥ 1000).RESULTS: At 12 months after ART initiation, the following VL distribution was found among 192 individuals (50% women): VL < 150, 122/192 (63.5%); VL150-999, 23/192 (12.0%); and VL ≥ 1000 47/192 (24.5%). IP-10 and HIV RNA levels were positively correlated (r = 0.481; P < 0.0001). Median IP-10 levels for the VL strata were VL < 150: 159 pg/mL [interquartile range (IQR) 121-246], VL150-999: 174 pg/mL (IQR 131-276), and VL ≥ 1000: 343 pg/mL (IQR 190-529), respectively. These differences were statistically significant for VL ≥ 1000 versus VL < 150 (adjusted P < 0.001) and VL150-999 (adjusted P = 0.004), respectively.CONCLUSIONS: IP-10 and HIV RNA levels during ART showed significant correlations, with significantly higher IP-10 concentration in ART recipients with VL ≥ 1000 copies/mL compared to those with suppressed or undetectable VL
Prevalence of Celiac Disease Autoimmunity in Ethiopian Pregnant Women: A Cross Sectional Study from the Oromia region
Celiac disease is a chronic small bowel disease induced by ingestion of gluten in genetically susceptible individuals affecting 1% among Caucasians in the Western world. The prevalence of celiac disease is still unknown in most developing countries, especially in Africa which suffer from lack of resources to perform screening of the general population. The aim of this study was to determine the prevalence of celiac disease autoimmunity in women undergoing antenatal care in selected Ethiopian health institutes. A total of 1942 pregnant women were included at median 25 (range 15-45) years of age who were attending antenatal care at 14 health centers of Central and South-East Oromia regional state of Ethiopia. Serum samples were analyzed for both IgA and IgG autoantibodies against tissue transglutaminase (tTG) using radioligand binding assays. Celiac disease autoimmunity defined as testing positive for both of IgA-tTG and IgG-tTG. In all, 4 of 1942 (0.2%) were positive for IgG-tTG of whom one participant (0.05%) was positive for both IgA-tTG and IgG-tTG and defined as having celiac disease autoimmunity. Based on these results, it was concluded that celiac disease autoimmunity is expected to be less common among the female adult Ethiopian population compared with the expected prevalence in Caucasians
Plasma Levels of Neopterin and C-Reactive Protein (CRP) in Tuberculosis (TB) with and without HIV Coinfection in Relation to CD4 Cell Count
Background While the risk of TB is elevated in HIV-positive subjects with low CD4 cell counts, TB may in itself be associated with CD4 lymphocytopenia. We investigated markers of immune activation (neopterin) and inflammation (CRP) in TB patients with and without HIV coinfection and their association with CD4 cell levels, and determined their predictive capacity as alternative markers of advanced immunosuppression. Methods Participants selected from a cohort of adults with TB at Ethiopian health centers (195 HIV +/TB+, 170 HIV-/TB+) and 31 controls were tested for plasma levels of neopterin and CRP. Baseline levels of neopterin and CRP were correlated to CD4 cell count before and after anti-TB treatment (ATT). The performance to predict CD4 cell strata for both markers were investigated using receiver operating curves. Results Levels of both biomarkers were elevated in TB patients (neopterin: HIV+/TB+ 54 nmol/l, HIV-/TB+ 23 nmol/l, controls 3.8 nmol/l; CRP: HIV+/TB+ 36 mu g/ml, HIV-/TB+ 33 mu g/ml, controls 0.5 mu g/ml). Neopterin levels were inversely correlated (-0.53, p&lt;0.001) to CD4 cell count, whereas this correlation was weaker for CRP (-0.25, p&lt;0.001). Neither of the markers had adequate predictive value for identification of subjects with CD4 cell count &lt;100 cells/mm(3) (area under the curve [AUC] 0.64 for neopterin, AUC 0.59 for CRP). Conclusion Neopterin levels were high in adults with TB, both with and without HIV coinfection, with inverse correlation to CD4 cell count. This suggests that immune activation may be involved in TB-related CD4 lymphocytopenia. However, neither neopterin nor CRP showed promise as alternative tests for immunosuppression in patients coinfected with HIV and TB.Funding Agencies|Swedish Civil Contingency Agency; Swedish International Development Cooperation Agency; Region Skane; Swedish Medical Association</p
Validation of the Viral Load Testing Criteria – an algorithm for targeted viral load testing in HIV-positive adults receiving antiretroviral therapy
Objectives: Restricted capacity for viral load (VL) testing is a major obstacle for antiretroviral therapy (ART) programmes in high-burden regions. Algorithms for targeted VL testing could help allocate laboratory resources rationally. We validated the performance of the Viral Load Testing Criteria (VLTC), an algorithm with satisfactory performance in derivation (sensitivity 91%, specificity 43%). Methods: HIV-positive adults who had been receiving first-line ART for ≥12 months at three Ethiopian public ART clinics were included. Healthcare providers collected data on variables of the VLTC: current CD4 count, mid-upper arm circumference (MUAC) and self-reported treatment interruption. VL testing was performed in parallel. Performance of the algorithm for identification of patients with VL ≥ 1000 copies/ml was evaluated. Results: Of 562 patients (female 62%, median ART duration 92 months), 33 (6%) had VL ≥ 1000 copies/ml. Sensitivity for the VLTC was 85% (95% CI, 68–95), specificity 60% (95% CI, 55–64), positive predictive value 12% (95% CI, 10–14) and negative predictive value 98% (95% CI, 97–99). Use of the algorithm would reduce the number of VL tests required by 57%. Misclassification occurred in 5/33 (15%) of subjects with VL ≥ 1000 copies/ml. Conclusion: In validation, the VLTC performed similarly well as derivation. Use of the VLTC may be considered for targeted VL testing for ART monitoring in high-burden regions
