    Sero-prevalence and Predictors of Syphilis and HIV Co-infection among pregnant women attending ANC in Mekelle City of Conflict-Affected Tigray Region, Ethiopia: Evidence from Firth Penalized Regression
    (Mekelle University, 2024-11-21) SENAIT HADDIS
    Background: Sexually transmitted infections (STIs), particularly syphilis and HIV, significantly impact pregnant women in resource-limited countries, complicating treatment and increasing maternal and neonatal risks. In Mekelle City, Tigray, Ethiopia, barriers including limited antenatal care (ANC) access, physiological vulnerability, behavioral risks, socio-economic constraints, and conflict further exacerbate the burden of these infections, underscoring the critical need for accurate prevalence data and identification of predictive factors. Objective: This study aimed to determine the sero-prevalence of HIV/syphilis co-infection and identify associated predictors among pregnant women attending ANC in Mekelle City. Method: A facility-based cross-sectional study was conducted among pregnant women attending ANC services in selected health facilities across Mekelle City, Tigray, Ethiopia. A two-stage stratified sampling procedure was utilized to draw representative pregnant women under ANC from a health facility in each sub city. Data collection involved an interview-administered questionnaire and pregnant women’s registration books. Due to the relatively small sample size and rarity of co-infection events, Firth penalized logistic regression was employed for statistical analysis to mitigate bias and ensure model stability. Adjusted odds ratios (AOR) with 95% confidence intervals (CI) were computed to identify significant predictors. Result: Out of 438 pregnant women enrolled, the sero-prevalence of HIVsyphilis co-infection was 3.7% (95% CI: 1.87–5.43%). Significant predictors included sexual violence (frequency: 13.7%; AOR=2.2, 95% CI: 1.27–3.81, p=0.001), displacement (frequency: 41.1%; AOR=1.6, 95% CI: 1.10–2.32, p=0.043), frequent alcohol consumption (most frequent: 8.9%; AOR=2.1, 95% CI: 1.27–3.46, p=0.004), and limited ANC visits (frequency: 47.5%; AOR=1.8, 95% CI: 1.13–2.87, p=0.014). Conclusion & Recommendation: The high prevalence of HIV and syphilis co-infection rate underscores the need for targeted sexual violence prevention, improved ANC access, and integrated STI screening within ANC services in Mekelle City. Enhanced education on substance abuse and sexual health is essential.

    Assessment and Comparison of Serum Electrolyte Level among Pulmonary Tuberculosis Patients with and without HIV Co-infection at Ayder Comprehensive Specialized Hospital, Tigray, North Ethiopia, 2023/2024
    (Mekelle University, 2025-01-25) Tsegay G/her Birhane
    According to a World Health Organization report from 2021, tuberculosis is a primary cause of morbidity and one of the top causes of mortality globally. It has been discovered that electrolyte and fluid imbalances, which are common in tuberculosis and HIV/AIDS, have a significant role in morbidity and mortality. The aim of this study was to assess and compare serum electrolyte level among pulmonary tuberculosis patients with or without HIV co-infection at Ayder Comprehensive Specialized Hospital, Tigray, North Ethiopia. A comparative cross-sectional study utilizing a convenience sampling technique was used to sample 50 pulmonary tuberculosis patients with or without HIV co-infection at Ayder Comprehensive Specialized Hospital in the period from October 2023 to December 2024. HIV-PTB co-infected patients and PTB without HIV co-infection who fulfilled the inclusion criteria were included in the study. Socio-demographic and clinical data were collected using an interviewer administered structured questionnaire and medical record review. K-Light electrolyte analyser automachine analyser was used to determine the serum electrolyte status of pulmonary tuberculosis patients with or without HIV co-infection directly by taking 3 milliliters of venous blood. After checking for completeness and cleaning, the data were entered into Epi-data version 4.5 and exported into the SPSS software version 25 package for analysis, and the different variables were analyzed. Linear Regression was used to assess the relationship of anti-TB and ART Rx duration with serum electrolyte level. This study found that serum sodium levels were significantly higher in pulmonary tuberculosis (PTB) patients compared to those co-infected with HIV (132.65±4.15 vs. 130.28±4.09 mEq/L; p = 0.047). Conversely, serum potassium levels were significantly elevated in HIV-PTB coinfected patients (5.05±0.75 vs. 3.83±0.59 mEq/L; p = 0.000), and serum chloride levels were higher in PTB patients without HIV co-infection (103.42±3.16 vs. 100.61±5.10 mEq/L; p = 0.023). The study highlights the significantly higher level of serum sodium in pulmonary tuberculosis (PTB) patients without HIV co-infection compared to those co-infected with HIV. This study also showed a significantly higher level of serum potassium in HIV-PTB co-infected patients and significantly higher chloride level in PTB patients without HIV co-infection.
