Clinicopathological Features and Survival of Patients with Hepatocellular Carcinoma in Ethiopia: A Multicenter Study

(1) Background: Hepatocellular carcinoma (HCC) is one of the deadliest cancers globally, killing over 700,000 people each year. Despite the rising incidence and mortality rates of HCC in Ethiopia, only few single-centered studies have been conducted; therefore, we aimed to explore the clinicopathological characteristics and survival of patients with HCC in multicenter settings. (2) Methods: We conducted a retrospective analysis of 369 patients with confirmed HCC diagnosed between 2016 and 2021. The survival of patients weas determined using the Kaplan−Meier method, and hazard ratios of the prognostic factors were estimated in Cox proportional hazard models. (3) Results: Majority patients were male (67%) and had a mean age of 52.0 ± 15.6 years. The majority of patients (87%) had a large tumor size (>5 cm) at diagnosis and presented with an advanced-stage condition. Cirrhosis (58%) and viral hepatitis (46.5%) were the main risk factors associated with HCC. The median overall survival was 141 days (95% CI: 117−165). Patients who took antivirals for HBV had a higher survival benefit compared to the untreated group (469 vs. 104 days; p < 0.001). The risk of death was 12 times higher in patients with Barcelona Clinic Liver Cancer-D (BCLC-D) terminal stage HCC compared to patients with an early stage (BCLC-A) HCC. The stage of HCC and treatment against HBV are the most significant survival predictors. (4) Conclusions: The overall survival of HCC patients in Ethiopia is poor. Cirrhosis and viral hepatitis are the primary risk factors linked with HCC. Patients who received antiviral therapy for HBV had a better survival outcome.

Challenges of Anticoagulation Management Service and Need of Establishing Pharmacist-Led Anticoagulation Clinic in Tertiary Care Teaching Hospital, Ethiopia: A Qualitative Study

Pupose

To explore the challenges of anticoagulation management (AMS) and assess the need for establishing a pharmacist-led anticoagulation clinic (PLAC) at Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa, Ethiopia.

Methods

We conducted a qualitative study at TASH. Using a semistructured interview guide, we interviewed 15 physicians from different specialties, heads of pharmacy and laboratory departments. We also included 20 patients to explore their general perceptions, and experiences with and challenges of AMS; and the need to implement PLAC in the hospital.

Results

Only three physicians responded that they had protocols for initiating and maintaining warfarin dosing. Having protocols for venous thromboembolism (VTE) risk assessment, VTE prophylaxis and treatment, bleeding risk assessment, and contraindication to anticoagulant therapy were reported by seven, six, four, and three participants, respectively. Lack of trained healthcare professionals and a separate AMS clinic, inconsistency in INR testing and anticoagulant availability, and longer appointment times were the biggest challenges of the existing AMS, according to 80% of respondents. Fourteen patient respondents indicated that their satisfaction with the AMS was affected by long wait times and inconsistent availability of anticoagulants and INR testing. The head of the laboratory stated that the facilities for INR testing are inadequate and affect the quality of AMS and customer satisfaction, and supplemented by the head of the pharmacy by adding irregularities of supplies and inadequate counseling on anticoagulants. Respondents suggested that there is a need to establish a PLAC with well-adopted standard operating procedures, qualified manpower, adequate training of assigned staff, and sustained supply of anticoagulants and INR testing.

Conclusion

The hospital’s AMS is not optimal to provide adequate services during the study period. Based on these findings and recommendations, the supporting literature, and the experiences of other facilities, the PLAC was established in TASH.

Prevalence of soil-transmitted helminths infections among preschool and school-age children in Ethiopia: a systematic review and meta-analysis

BACKGROUND

There is a lack of comprehensive national data on prevalence, geographical distribution of different species, and temporal trends in soil-helminthiasis (STHs). Therefore, this study aimed to provide a summary and location of the available data on STHs infection among preschool and school-age children in Ethiopia.

METHODS

The search was carried out in Medline via PubMed, Scopus, Science Direct, Web of Science, and Google Scholar on data published between 1997 to February 2020 for studies describing the rate of STHs infection among preschool and school-age in Ethiopian. We followed the Patient, Intervention, Comparison, and Outcome (PICO) approach to identify the studies. Meta-regression was performed to understand the trends and to summarize the prevalence using the "metaprop" command using STATA software version 14.0 RESULTS: A total of 29,311 of the 61,690 children examined during the period under review were infected with one or more species of intestinal parasites yielding an overall prevalence of 48% (95% CI: 43-53%). The overall pooled estimate of STHs was 33% (95% CI: 28-38%). The prevalence was 44% (95% CI: 31-58%) in SNNPR, 34% (95% CI: 28-41%) in Amhara region, 31% (95% CI: 19-43%) in Oromia region and 10% (95% CI: 7-12%) in Tigray region. Soil-transmitted helminths infection rate has been decreasing from 44% (95% CI: 30-57%) pre-Mass Drug Administration (MDA) era (1997-2012) to 30% (95% CI: 25-34%) post-MDA (2013-2020), although statistically not significant (p = 0.45). A lumbricoides was the predominant species with a prevalence of 17%.

CONCLUSION

Southern Nations Nationalities and Peoples Region, Amhara, and Oromia regions carry the highest-burden and are categorized to Moderate Risk Zones (MRZ) and therefore, requiring MDA once annually with Albendazole or Mebendazole. The prevalence of STHs decreased after MDA compared to before MDA, but the decline was not statistically significant. A. lumbricoides was the predominant species of STHs among preschool and school-age children in Ethiopia. The high prevalence of STHs observed in this review, underscores the need for better control and prevention strategies in Ethiopia.

Prevalence and antimicrobial susceptibility of group B streptococci among pregnant women in Ethiopia: A systemic review and meta-analysis study

Objective:

Maternal colonization or infection with drug-resistant Group B streptococcus is a serious disease that affects mother, fetus, and infant. The knowledge of maternal colonization and antimicrobial susceptibility test is substantially needed for a nation to formulate a policy or change the already existing one to reduce maternal, fetus, and infant mortality. As a result, the goal of this review was to determine the pooled prevalence Group B streptococcus colonization and antimicrobial susceptibility among Ethiopian pregnant women.

Methods:

Literature searches were carried out in the electronic biomedical databases and indexing services such as PubMed/MEDLINE, Scopus, Science Direct, Web of Science, and Google Scholar. Original records of research articles, available online from 2014 to December 2020, addressing prevalence and antimicrobial-resistance pattern of Group B streptococcus in pregnant women were identified and screened. Endnote citation manager software version X9 for windows was utilized to collect and organize search outcomes and for removal of duplicate articles. The relevant data were extracted from included studies using a format prepared in Microsoft Excel and exported to STATA 14.0 software for the outcome measures analyses and subgrouping. The I2 index was used to measure heterogeneity between studies and median, and interquartile (25%, 75%) was used to assess antimicrobial susceptibility rate.

Results and conclusion:

Sixteen original articles were found in both qualitative and quantitative analyses. Group B streptococcus colonization was recorded in 979 of the 5743 pregnant women, resulting in a 16% overall frequency (95% confidence interval: 13%−20%). The estimated prevalence varied significantly between studies with significant heterogeneity (χ2 = 154.31, p = 0.001, I2 = 90.28). Ampicillin (97.8%; interquartile range = 89.5%−100%), penicillin G (95.5%; interquartile range = 89.5%−100%), and vancomycin (100%; interquartile range = 89.5%−100%) susceptibility were all high in Group B streptococcus, whereas tetracycline (29%; interquartile range = 89.5%−100%) susceptibility was low. Group B streptococcus colonization rates in Ethiopian women during pregnancy were virtually similar to those in many underdeveloped countries, and Group B streptococcus isolates were highly sensitive to ampicillin, penicillin G, and vancomycin.

Bacterial profile and antimicrobial resistance patterns of common bacteria among pregnant women with bacteriuria in Ethiopia: a systematic review and meta-analysis

Background

Globally, antimicrobial resistance (AMR) restricted the armamentarium of the health care providers against infectious diseases, mainly due to the emergence of multidrug resistant. This review is aimed at providing contemporary bacterial profile and antimicrobial resistance pattern among pregnant women with significant bacteriuria.

Methods

Electronic biomedical databases and indexing services such as PubMed/MEDLINE, Web of Science, EMBASE and Google Scholar were searched. Original records of research articles, available online from 2008 to 2021, addressing the prevalence of significant bacteriuria and AMR pattern among pregnant women and written in English were identified and screened. The relevant data were extracted from included studies using a format prepared in Microsoft Excel and exported to STATA 14.0 software for the outcome measure analyses and subgrouping.

Results

The data of 5894 urine samples from 20 included studies conducted in 8 regions of the country were pooled. The overall pooled estimate of bacteriuria was 15% (95% CI 13–17%, I² = 77.94%, p < 0.001) with substantial heterogeneity. The pooled estimate of Escherichia coli recovered from isolates of 896 urine samples was 41% (95% CI 38–45%) followed by coagulase-negative Staphylococci, 22% (95% CI 18–26%), Staphylococcus aureus, 15% (95% CI 12–18%), Staphylococcus saprophytic, 12% (95% CI 6–18%) Proteus mirabilis, 7% (95% CI 4–10%), Enterococcus species, 6% (0–12%), Pseudomonas aeruginosa, 4% (2–6%), Citrobacter species, 4% (95% CI 2–4%), Group B streptococcus, 3% (1–5%), and Enterobacter species, 2% (1–4%). Multidrug resistance proportions of E. coli, Klebsiella species, Staphylococcus aureus and Coagulase negative staphylococci, 83% (95% CI 76–91%), 78% (95% CI 66–90%), 89% (95% CI 83–96%), and 78% (95% CI 67–88%), respectively.

Conclusion

The result of current review revealed the occurrence of substantial bacteriuria among pregnant women in Ethiopia. Resistance among common bacteria (E. coli, Klebsiella species, Staphylococci species) causing UTIs in pregnant women is widespread to commonly used antibiotics. The high rate of drug resistance in turn warrants the need for regular epidemiological surveillance of antibiotic resistance and implementation of an efficient infection control and stewardship program.

Clinicians' prescribing pattern, rate of patients' medication adherence and its determinants among adult hypertensive patients at Jimma University Medical Center: Prospective cohort study

Background

Many studies conducted in the past focused on patients’ sociodemographic factors and medical profiles to identify the determinants of suboptimal blood pressure control. However, prescribing patterns and clinicians’ adherence to guidelines are also important factors affecting the rate of blood pressure control. Therefore, this study aimed to determine clinicians’ prescribing patterns, patients’ medication adherence, and its determinants among hypertensive patients at Jimma University Medical Center.

Methods

A general prospective cohort study was conducted among hypertensive patients who had regular follow-up at Jimma university ambulatory cardiac clinic from March 20, 2018, to June 20, 2018. Patients’ specific data was collected with a face-to-face interview and from their medical charts. Clinicians’ related data were collected through a self-administered questionnaire. Data were analyzed using SPSS version 21.0. Bivariate and multivariable logistic regression analyses were done to identify key independent variables influencing patients’ adherence. P-Values of less than 0.05 were considered statically significant.

Results

From the total of 416 patients, 237(57.0%) of them were males with a mean age of 56.50 ± 11.96 years. Angiotensin-converting enzyme inhibitors were the most frequently prescribed class of antihypertensives, accounting for 261(63.7%) prescriptions. Combination therapy was used by the majority of patients, with 275 (66.1%) patients receiving two or more antihypertensive drugs. Patients’ medication adherence was 46.6%, while clinicians’ guideline adherence was 44.2%. Patients with merchant occupation (P = 0.020), physical inactivity (P = 0.033), and diabetes mellitus co-morbidity (P = 0.008) were significantly associated with a higher rate of medication non-adherence.

Conclusion

The rate of medication adherence was poor among hypertensive patients. Physicians were not-adherent to standard treatment guideline. The most commonly prescribed class of drugs were angiotensin-converting enzyme inhibitors. Effective education should be given to patients to improve medication adherence. Prescribers should be trained on treatment guidelines regularly to keep them up-to-date with current trends of hypertension treatment and for better treatment outcomes.

Rate of blood pressure control and its determinants among adult hypertensive patients at Jimma University Medical Center, Ethiopia: Prospective cohort study

Introduction

Despite the fact that the goals for the management of hypertension are well-defined and effective therapies are available, control of hypertension remains poor in countries with low resources including Ethiopia. This study aimed to determine blood pressure control rate and its determinants among ambulatory adult hypertensive patients at Jimma University Medical Center.

Methods

A general prospective cohort study was conducted among adult hypertensive patients who had regular follow-up at Jimma University Cardiac Clinic from 20 March to 20 June 2018. Hypertensive patients who fulfilled the inclusion criteria were selected in the first month of the data collection period. Then, only those patients who visited the clinic at the first month were consequently followed-up for the next 3 months. The Eighth Joint National Committee guideline was used to categorize controlled and uncontrolled blood pressures. Patients' specific data were collected using a structured data collection tool. Data were analyzed using the statistical software package SPSS version 21.0. Bivariate and multivariable logistic regression analysis was used to identify independent variables influencing blood pressure control. p-values of less than 0.05 were considered statistically significant.

Results

From a total of 416 patients, 237 (57.0%) were male with a mean age of 56.50 ± 11.96 years. Two hundred and fifty eight (62.0%) participants had comorbid conditions and 275 (66.1%) were on combination therapy. The rate of blood pressure control was 42.8%. Age ⩾60 years was negatively associated with uncontrolled blood pressure (adjusted odd ratio = 0.52, confidence interval = 0.31-0.88, p = 0.015). Medication non-adherence (adjusted odd ratio = 1.64, confidence interval = 1.04-2.58, p = 0.034) and non-adherence to international guidelines (adjusted odd ratio = 2.33, confidence interval = 1.49-3.64, p < 0001) were positively associated with uncontrolled blood pressure.

Conclusion

The rate of blood pressure control among hypertensive patients was suboptimal. Age, clinicians' non-adherence to international guidelines, and patients' non-adherence to medications were independent predictors of blood pressure control. Physicians and clinical pharmacists should adhere to guidelines for better treatment and care of hypertensive patients.

Management and 30-Day Mortality of Acute Coronary Syndrome in a Resource-Limited Setting: Insight From Ethiopia. A Prospective Cohort Study

Background: Despite the fact that the burden, risk factors, and clinical characteristics of acute coronary syndrome (ACS) have been studied widely in developed countries, limited data are available from sub-Saharan Africa. Therefore, this study aimed at evaluating the clinical characteristics, treatment, and 30-day mortality of patients with ACS admitted to tertiary hospitals in Ethiopia. Methods: A total of 181 ACS patients admitted to tertiary care hospitals in Ethiopia were enrolled from March 15 to November 15, 2018. The clinical characteristics, management, and 30-day mortality were evaluated by ACS subtype. The Cox proportional hazards model was used to determine the predictors of 30-day all-cause mortality. A p-value < 0.05 was considered statistically significant. Results: The majority (61%) of ACS patients were admitted with ST-segment elevation myocardial infarction (STEMI). The mean age was 56 years, with male predominance (62.4%). More than two-thirds (67.4%) of patients presented to hospital after 12 h of symptom onset. Dyslipidemia (48%) and hypertension (44%) were the most common risk factors identified. In-hospital dual antiplatelet and statin use was high (>90%), followed by beta-blockers (81%) and angiotensin-converting enzyme inhibitors (ACEIs; 72%). Late reperfusion with percutaneous coronary intervention (PCI) was done for only 13 (7.2%), and none of the patients received early reperfusion therapy. The 30-day all-cause mortality rate was 25.4%. On multivariate Cox proportional hazards model analysis, older age [hazard ratio (HR) = 1.03, 95% CI = 1.003-1.057], systolic blood pressure (HR = 0.99, 95% CI = 0.975-1.000), serum creatinine (HR = 1.32, 95% CI = 1.056-1.643), Killip class > II (HR = 4.62, 95% CI = 2.502-8.523), ejection fraction <40% (HR = 2.75, 95% CI = 1.463-5.162), and STEMI (HR = 2.72, 95% CI = 1.006-4.261) were independent predictors of 30-day mortality. Conclusions: The 30-day all-cause mortality rate was unacceptably high, which implies an urgent need to establish a nationwide program to reduce pre-hospital delay, promoting the use of guideline-directed medications, and increasing access to reperfusion therapy.

Treatment Outcome and Associated Factors of Neonatal Sepsis at Mizan Tepi University Teaching Hospital, South West Ethiopia: A Prospective Observational Study

INTRODUCTION

Neonatal sepsis is the gravest problem in neonates, ending in significant morbidity and mortality. World wide 6.9 million neonates were spotted with potentially severe bacterial infections needing treatment and 2.6 million of them occurred in sub-Saharan Africa (SSA). Sepsis is the leading cause of neonatal mortality and is perhaps answerable for about 30-50% of the total neonatal deaths per year in emerging countries.

OBJECTIVE

This study aims to assess the treatment outcome and associated factors of neonatal sepsis at Mizan Tepi University Teaching Hospital, South West Ethiopia.

METHODS

A hospital-based prospective observational study was done at Mizan Tepi University Teaching Hospital (MTUTH) from May to November 2019 among neonates admitted with sepsis. Data were entered to Epi-data 4.2 and analyzed by SPSS version 21. Bivariate and multivariate Cox regression was used to identify the relationship between dependent and independent variables. All neonates ≤28 days who were admitted to MTUTH at the neonatal intensive care unit (NICU) and neonates diagnosed with sepsis by the attending physician either clinically or laboratory-confirmed included in the study.

RESULTS

Of the 211 neonatal sepsis patients, 110 (52.1%) were females, 161 (76.3%) were admitted with late-onset sepsis, 16 (7.6%) were very low birth weight, and 156 (73.9%) were term. About 143 (67.8%) had a good outcome and 68 (32.2%) had a poor outcome. Very low birth weight [P = 0.006, AHR = 1.692, 95% CI: (1.245, 4.36)], age of neonate being less than 4 days at admission [P = 0.001, AHR = 9.67, 95% CI: (2.24, 41.70)], maternal infection [P = 0.032, AHR = 3.186, 95% CI: (1.32, 30.68)], and prolonged length of hospital stay [(P = 0.017, AHR = 12.29, 95% CI: (1.55, 96.31), were significantly associated to mortality.

CONCLUSION

The mortality rate of neonatal sepsis was found to be high. Age of neonate <4 days, birth weight of the neonate <1500 gm, and prolonged length of hospital stay were identified as independently associated factors of increased risk of mortality.

Burden of intestinal parasitic infections among pregnant women in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Comprehensive nationwide data on prevalence and distribution of intestinal parasites (IPIs) among pregnant women are lacking. Therefore, the aim of this study was to provide pooled prevalence estimate, prevalence in different regions and species-specific IPIs among pregnant women in Ethiopia.

METHODS

The search was carried out in Medline via PubMed, Scopus, Science Direct, Web of Science and Google Scholar on published and unpublished data between 2008 and Sep 2020 for studies describing rate of IPIs among pregnant women in Ethiopian. A random-effects model and forest plots to estimate pooled effect size and effect of each study with their confidence interval (CI) were used to provide a visual summary of the data. We conducted meta-regression to understand the source of heterogeneity and pooled the prevalence using 'metaprop' command using STATA software version 14.

RESULTS

A total of 3149 of the 9803 pregnant women were infected with one or more species of IPIs resulted in an overall prevalence of 29% (95% CI 22-37%). The prevalence estimate varied among studies with considerable heterogeneity (χ² = 2069.19, p < 0.001 I² = 98.84). The prevalence of IPIs was 36% (95% CI 22-50%) in Oromia region, 29% (95% CI 10-47%) in Amhara region, 24% (95% CI 17-32%) in southern nation, nationality and people region, 24% (95% CI 22-27%) in Tigray region and 24% (95% CI 20-29%) in Addis Ababa city. Hookworms with pooled prevalence estimate of 10% (95% CI 8-13%) followed by Ascaris lumbricoides 10% (95% CI 7-13%), and Entamoeba histolytica/dispar 6% (95% CI 4-8%) were the three common species of IPIs identified in this group of population.

CONCLUSION

The prevalence of IPIs among pregnant women is relatively high in comparison to other general population. Hookworms and Ascaris lumbricoides were the most dominant species of intestinal helminths, whereas Entamoeba histolytica/dispar was the dominant intestinal protozoa among pregnant women in Ethiopia.

Bacterial profile and antimicrobial susceptibility patterns of isolates among patients diagnosed with surgical site infection at a tertiary teaching hospital in Ethiopia: a prospective cohort study

BACKGROUND

Globally, surgical site infections are the most reported healthcare-associated infection and common surgical complication. In developing countries such as Ethiopia, there is a paucity of published reports on the microbiologic profile and resistance patterns of an isolates.

OBJECTIVE

This study aimed at assessing the bacterial profile and antimicrobial susceptibility patterns of isolates among patients diagnosed with surgical site infection at Jimma Medical Center in Ethiopia.

METHODS

A prospective cohort study was employed among adult patients who underwent either elective or emergency surgical procedures. All the eligible patients were followed for 30 days for the occurrence of surgical site infection (SSI). From those who developed SSI, infected wound specimens were collected and studied bacteriologically.

RESULTS

Of 251 study participants, 126 (50.2%) of them were females. The mean ± SD age of the patients was 38 ± 16.30 years. The overall postoperative surgical site infection rate was 21.1% and of these 71.7% (38/53) were culture positive. On gram stain analysis, 78% of them were Gram-negative, 11.5% were Gram-positive and 10.5% were a mixture of two microbial growths. Escherichia coli accounted for (21.43%), followed by Pseudomonas aeruginosa (19.05%), Proteus species (spp.) 14.29%), Staphylococcus aureus (11.90%), Klebsiella species (11.90%), Citrobacter spp. (9.5%), streptococcal spp. (7.14%), Coagulase-negative S. aureus (CoNS) (2.38%) CONCLUSION: Gram-negative bacteria were the most dominant isolates from surgical sites in the study area. Among the Gram-negative bacilli, Escherichia coli were the most common bacteria causing surgical site infection. As there is high antibiotic resistance observed in the current study, it is necessary for routine microbial analysis of samples and their antibiogram.

Evaluation of Adult Outpatient Antibiotics Use at Jimma Medical Center (with Defined Daily Doses for Usage Metrics)

Introduction

Inappropriate antibiotic use is a major public health concern and driver of antibiotic resistance. Excessive exposure to antibiotics results in the emergence and spread of drug-resistant microorganisms. This study aimed to measure the volume of antibiotic consumption at the outpatient settings in a tertiary-care teaching hospital in Ethiopia.

Methods

A cross-sectional study was undertaken from February 01, 2019 to March 31, 2019 at Jimma Medical Center in southwest Ethiopia. Antibiotics use was analyzed using Anatomical Therapeutic Chemical Classification and Defined Daily Dose (DDD) system. Antibiotic use was calculated as DDD per 100 outpatients per day. Antibiotics were classified based on World Health Organization "AWaRe" classification scheme as "Access", "Watch" and "Reserve" group antibiotics and measured their consumption intensity.

Results

A total of 496 adult patients were included in the study. The mean (SD) age of participants was 33.07 (14.05) years. The total amount of antibiotics consumed was 5.31 DDD/100 outpatients per day. Ciprofloxacin was the most commonly [122 (21.12%)] prescribed antibiotics with DDD/100 outpatients per day value of 1.13, followed by amoxicillin [68 (11.76%)] with DDD/100 outpatients per day value of 0.44, and azithromycin [61 (10.55%)] with DDD/100 outpatients per day value of 0.51. On antibiotic consumption index, antibiotics in the "Watch" group had 2.10 DDD/100 outpatients per day.

Conclusion

There was high consumption of antibiotics in the study setting. Based on the use control criteria, half of the antibiotics used were in the "Watch" group. The high level of consumptions of antibiotics, such as ciprofloxacin, norfloxacin, and azithromycin, in particular, requires further scrutiny and calls for an urgent implementation of an antibiotic stewardship program at the hospital.

Management quality indicators and in-hospital mortality among acute coronary syndrome patients admitted to tertiary hospitals in Ethiopia: prospective observational study

Background

Acute coronary syndrome (ACS) remains the leading cause of cardiovascular disease mortality and morbidity worldwide. While the management quality measures and clinical outcomes of patients with ACS have been evaluated widely in developed countries, inadequate data are available from sub-Saharan Africa countries. So, this study aimed to assess the clinical profiles, management quality indicators, and in-hospital outcomes of patients with ACS in Ethiopia.

Methods

A Prospective observational study was conducted at two tertiary hospitals in Ethiopia from March 2018 to November 2018. The primary outcome of the study was in-hospital mortality. Data were analyzed using SPSS version 23.0. Multivariable cox-regression was conducted to identify predictors of time to in-hospital mortality. Variable with p -value < 0.05 was considered statistically significant.

Results

Among 181 ACS patients enrolled, about (61%) were presented with ST-elevation myocardial infarction (STEMI). The mean age of the study participant was 55.8 ± 11.9 years and 62.4% were males. The use of guideline-directed medications within 24 h of hospitalization were sub-optimal (57%) [Dual antiplatelet (73%), statin (74%), beta-blocker (67%) and ACEI (61%)]. Only (7%) ACS patients received the percutaneous coronary intervention (PCI). Discharge aspirin and statin were high (> 90%) while other medications were sub-optimal (< 80%). The all-cause in-hospital mortality rate was 20.4% and the non-fatal MACE rate was 25%. Rural residence (AHR: 3.64, 95% CI: 1.81–7.29), symptom onset to hospital arrival > 12 h (AHR: 4.23, 95% CI: 1.28–13.81), and Cardiogenic shock (AHR: 7.20, 95% CI: 3.55–14.55) were independent predictors of time to in-hospital death among ACS patients.

Conclusion

In the present study, the use of guideline-directed in-hospital medications was sub-optimal. The overall in-hospital mortality rate was unacceptably high and highlights the urgent need for national quality-improvement focusing on timely initiation of evidence-based medications, reperfusion therapy, and strategies to reduce pre-hospital delay.

Incidence, risk factors and outcomes of surgical site infections among patients admitted to Jimma Medical Center, South West Ethiopia: Prospective cohort study

Background

Surgical site infections are one of the leading health care–associated infections in developing countries. Despite improvements in surgical technique and the use of best infection prevention strategies, surgical site infections remained the major cause of hospital acquired infections. Therefore, this study aimed to determine incidence, risk factors, and outcomes of surgical site infections among patients admitted to Jimma Medical Center, South West Ethiopia.

Methods

A hospital based prospective cohort study design was employed to follow adult patients admitted to general surgery ward, orthopaedic ward and gynaecologic/obstetrics ward of Jimma Medical Centre, from April 20 to August 20, 2019. All patients were followed daily before, during and after operation for 30 days to determine the incidence of surgical site infection and other outcomes. Data was entered using EpiData version 4.2 and analyzed using statistical software package for social science version 20.0. To identify the independent predictors of outcome, multiple stepwise backward cox regression analysis was done. Statistical significance was considered at p-value <0.05.

Results

Of total of 251 participants included to the study, about 126 (50.2%) of them were females. The mean ± SD age of patients was 38 ± 16.30 years. Considerable number of patients 53(21.1%) developed surgical site infections. American Society of Anaesthesiologists score ≥3 [ Adjusted Hazard Ratio (AHR) = 2.26; 95%CI = (1.03–4.93)], postoperative antibiotic prescription [AHR = 3.2; 95%CI = (1.71–6.01)], contaminated-wound [AHR = 7.9; 95%CI = (4.3–14.60)], emergency surgery [AHR = 2.8; 95% CI = (1.16–6.80)], duration of operation ≥ 2 h [AHR = 4; 95% CI = (2.17–7.50)] and comorbidity [AHR = 2.52; 95%CI = (1.28–4.94)] were independent predictors for surgical site infections. Twenty nine (11.6%) patients returned to operation room. The result of the multivariate cox regression analysis showed that SSI [AHR (95% CI) = 7(3.16–15.72)], and incision site [AHR (95% CI) = 2.5(1.14–5.42)] had statistically significant association with re-operation

Conclusion

The incidence of surgical site infection was high in the study setting. There were significant numbers of contributing factors for the occurrence of surgical site infections. Although no mortality observed during the study period, significant number of patients re-operated. Large multicenter study is urgently needed to confirm the outcome of this study.

•

Surgical site infections are one of the leading health care–associated infections in developing countries.

•

Considerable number of risk factors are associated with the occurrence of surgical site infection.

•

Surgical site infection is associated with increased length of hospital stay and number of patients re-operated.

Gram-Negative Bacteria Isolates and Their Antibiotic-Resistance Patterns in Patients with Wound Infection in Ethiopia: A Systematic Review and Meta-Analysis

BACKGROUND

Antibiotic resistance (ABR) restricts the armamentarium of health-care providers against infectious diseases due to the emergence of multidrug resistance (MDR), especially in Gram-negative bacteria. This study aimed to determine pooled estimates of Gram-negative bacteria, their resistance profiles, and rates of MDR in patients with wound infection in Ethiopia.

METHODS

Electronic databases such as PubMed/MEDLINE, EMBASE, Science Direct, Web of Science, and Google Scholar were searched. Original articles, available online from 1988 to 2020, addressing the prevalence and resistance patterns of Gram-negative bacteria in patients with wound infection and written in English were screened. The data were extracted using a format prepared in Microsoft Excel and exported to STATA 14.0 for the outcome analyses.

RESULTS

The data of 15,647 wound samples, from 36 studies conducted in 5 regions of the country, were pooled. The overall pooled estimate of Gram-negative bacteria was 59% [95% CI: 52-65%, I2 = 96.41%, p < 0.001]. The pooled estimate of Escherichia colirecovered from isolates of 5205 wound samples was 17% [95% CI: 14-20%], followed by Pseudomonas aeruginosa, 11% [95% CI: 9-14%], Klebsiella pneumonia, 11% [95% CI: 9-13%], Proteus mirabilis, 8% [95% CI: 6-10%], Acinetobacter species, 4% [95% CI: 2-6%], Enterobacter species, 4% [95% CI: 3-5%], and Citrobacter species, 3% [95% CI: 2-4%]. Multidrug resistance prevalence estimates of E. coli, K. pneumonia, P. aeruginosa, P. mirabilis, Citrobacter species, Enterobacter species and Acinetobacter species were 76% [95% CI: 66-86%], 84% [95% CI: 78-91%], 66% [95% CI:43-88%], 83% [95% CI:75-91%], 87% [95% CI:78-96%], 68% [95% CI:50-87%] and 71% [95% CI:46-96%], respectively.

CONCLUSION

There was high resistance in Gram-negative bacteria from wound specimens to commonly used antibiotics in Ethiopia. The data warrant the need of regular epidemiological surveillance of antimicrobial resistance and implementation of an efficient infection control program.

Prevalence and Impact of Metabolic Syndrome on Short-Term Prognosis in Patients with Acute Coronary Syndrome: Prospective Cohort Study

PURPOSE

Despite the increasing burden of metabolic syndrome (MS) and ischemic heart disease in sub-Saharan Africa, data on the prevalence of MS among patients with acute coronary syndrome (ACS) from the regions are limited. Hence, this study is aimed to evaluate the prevalence and impact of MS on 30-day all-cause mortality in patients hospitalized with ACS.

PATIENTS AND METHODS

We prospectively assessed 176 ACS patients, who were admitted to two tertiary hospitals in Ethiopia. MS was diagnosed based on a harmonized definition of MS. In-hospital major adverse cardiovascular events (MACE) and 30-day mortality were recorded. Multivariable cox-regression was used to identify predictors of 30-day mortality.

RESULTS

Among 176 ACS patients enrolled, 62 (35.2%) had MS. Majority of the patients (62.5%) were male with the mean age of 56±11.9 years. ACS patients with MS were older, presented with atypical symptoms, and they had history of hypertension, diabetes, dyslipidemia and coronary artery disease compared to those without MS. MS was also significantly associated with in-hospital MACE (30.6% vs 17.5%; p= 0.046) and 30-day mortality [adjusted hazard ratio (AHR) = 3.25, 95% CI=1.72-6.15]. The other significant predictors of 30-day mortality were pre-hospital delay >12h (HR= 4.32, 95% CI=1.68-11.100), killip class ≥2 (HR=10.7, 95% CI= 2.54-44.95), and ejection fraction <40 (HR= 2.59 95% CI=1.39-4.84).

CONCLUSION

The prevalence of MS among patients with ACS in Ethiopia is high. MS was significantly associated with high in-hospital MACE and it was an independent predictor of 30-day mortality. Initiating appropriate strategies on MS prevention and timely diagnosis of MS components could decrease the burden of ACS and improve patient's outcome.

Impact of HIV status and predictors of successful treatment outcomes among tuberculosis patients: A six-year retrospective cohort study

Tuberculosis (TB) remains a major global public health problem. Hence, the study aimed to assess the impact of human immune virus (HIV) status and predictors of successful treatment outcomes of TB patients enrolled at Nekemte specialized hospital. An institution-based retrospective cohort study was conducted and the data analyzed using SPSS version 24.0. A multivariable logistic regression model was fitted to identify the association between treatment outcome and potential predictor variables. The association was calculated using the Adjusted Odds ratio (AOR) and the statistical significance was considered at p < 0.05. Out of the total 506 study participants, 50.2% of them were males. The overall treatment success rate was 81.4% and 58.06% among HIV co-infected TB patients. Female sex (AOR = 2.01, 95%CI: 1.04–16.11), age 25–34 years (AOR = 3.982, 95%CI: 1.445–10.971), age 35–49 years (AOR = 5.392, 95%CI: 1.674–17.368), high school educational level (AOR = 5.330, 95% CI: 1.753–16.209), urban residence (AOR = 3.093, 95%CI: 1.003–9.541) and HIV negative (AOR = 10.3, 95%CI, 3.216–32.968) were positively associated with favorable TB treatment outcome. Whereas, being single (AOR = 0.293, 95%CI: 0.1–0.854), smear-negative pulmonary TB (AOR = 0.360, 95%CI: 0.156–0.834), extra-pulmonary TB (AOR = 0.839, 95%CI: 0.560–0.955) and retreatment case (AOR: 0.54, 95%CI: 0.004–0.098) were negatively associated with successful treatment outcome. The treatment success rate of TB patients was lower than World Health Organization target set of 85%. The increased unsuccessful outcome among TB/HIV patients requires urgent public health interventions to improve the evaluation policy and control framework.

•

Tuberculosis (TB) remains a major global public health problem.

•

TB is the leading cause of death for HIV-infected patients, and HIV is also risk factor for developing active TB.

•

The co-infection has emerged as a major public health threat throughout the world and have worse treatment outcomes.

•

Management of co-infected patients can be complex because of overlapping drug toxicities and interactions.

•

The increased unsuccessful outcome among TB/HIV patients requires urgent public health interventions.

Amputation rate of diabetic foot ulcer and associated factors in diabetes mellitus patients admitted to Nekemte referral hospital, western Ethiopia: prospective observational study

BACKGROUND

Diabetes foot ulcer is a devastating and much-feared complication of diabetes. Diabetes foot ulcerations which developed gangrene can take weeks or months to heal and can sometimes not heal at all so that amputation for non-traumatic causes is a frequent outcome in the diabetic foot. Despite this, there is no finding on predictors of the amputation rate of diabetes foot ulcers in Ethiopia. Hence this study was aimed to identify factors associated with the amputation rate of diabetes foot ulcer patients in Nekemte referral hospital.

PATIENTS AND METHODS

A prospective observational study was conducted among adult diabetes foot ulcer patients admitted to Nekemte referral hospital from March 15 to June 15, 2018. A pus swab was obtained from the ulcers before any ulcer cleaning to conduct gram staining. The primary outcome was the amputation rate. Cox regression analysis was used to estimate the hazard ratios and time from study entry to healing was evaluated as censored event times by Kaplan-Meier curves.

RESULT

Over the study period, 115 diabetes foot ulcer patients were admitted to the NRH; of these patients, 64(55.65%) were males while the mean age of participants was 44.4 ± 14.7. A total of 34(29.57%) of the diabetes foot ulcer were overweight and 16(13.91%) were obese while the mean ± standard deviation of body mass index (BMI) was 24.94 ± 3.69 kg/m2 and a total of 56(48.69%) diabetic foot ulcer had a diabetic complication. Of patients with diabetic foot ulcer, 35(30.43%) were undergone lower extremity amputations (LEA). Patients who were prescribed with inappropriate antibiotics were unlikely to heal. A total of 18(46.15%) of the patients who were taken inappropriate antibiotics were healed whereas 21(53.85%) were not healed (P = 0.017). Besides, the higher the Wagner grade, the worse the outcome of healing. A total of 19(21.84%) and 16(57.14%) of patients with grade < 4 and grade ≥ 4, respectively, did not heal (P = 0.005).

CONCLUSION

The amputation rate of diabetes foot ulcers was rapid for patients prescribed inappropriate antibiotics and higher grades of the foot ulcer. Therefore, the presence of clinical pharmacists plays a pivotal role to promote the appropriate use of antibiotics and besides the daily care, special attention should be given for patients having an advanced grade of diabetes foot ulcer.

<p>Clinical, Echocardiographic Characteristics and Management Practices in Patients with Rheumatic Valvular Heart Disease</p>

Background

Rheumatic heart disease (RHD) is the long-term consequence of acute rheumatic fever (ARF), continues unabated among middle-income and low-income countries. Thus, this study aimed to assess clinical characteristics, echocardiographic characteristics, and management practice of RHD patients.

Methods

Hospital-based prospective cross-sectional study was used. The data were collected from medical records of consecutive patients admitted to medical wards during the study period. The data were cleaned and analyzed using SPSS version 20. Descriptive statistics were used to describe the data. Chi-square was used to compare proportions between categorical variables.

Results

Forty-seven patients with a median (IQR) age of 28.0 (17.0-40.0) years were included. Pan systolic murmur was reported in 91.50% of patients. Forty-two (89.4%) of patients were presented with congestive heart failure and 23 (48.9%) with atrial fibrillation. Mitral valve leaflet thickening and calcification with restriction of motion were reported in 91.5% of patients. Mitral regurgitation (MR) (87.2%) and stenosis (MS) (85.1%) were the most common valvular lesions. The combinations of three (MR+MS+TR) 14 (29.8%) and four (MR+MS+TR+AR) 13 (27.7%) valve diseases were most commonly reported. Diuretics (95.7%), anticoagulants (38.3%), digoxin (36.2%), and beta-blockers (34.0%) were among the commonly prescribed medications.

Conclusion

Rheumatic heart disease affected younger adults. Pansystolic murmur was reported in nearly all patients. Congestive heart failure and atrial fibrillation were common clinical presentations. Morphologic changes in mitral valve and pathologic mitral regurgitation were the most common echocardiographic reports. Cardiovascular medications were commonly utilized for symptomatic management of complications Therefore, echocardiography should be done routinely for patients with RHD, focusing on younger adults, to facilitate diagnosis and treatment before complications develop.

Deep Venous Thrombosis Recurrence and Its Predictors at Selected Tertiary Hospitals in Ethiopia: A Prospective Cohort Study

Deep venous thrombosis (DVT) is a common clinical problem associated with substantial morbidity and mortality. Knowledge of the global burden of DVT recurrence is deficient in Africa, including Ethiopia. The objective of the study was to assess deep venous thrombosis recurrence and its predictors at selected tertiary hospitals in Ethiopia. Prospective cohort study was conducted among hospitalized DVT patients. Data were analyzed using SPSS version 21.0. To identify the independent predictors of DVT-recurrence, multiple stepwise-backward Cox-regression analysis was done. Statistical significance was considered at P value < .05. A total of 129 participants were included (65.1% females) with mean ± SD age of 38.63 ± 17.67 years. About 26.4% of patients developed recurrent venous thromboembolism. Pulmonary embolism accounted for 17.60% of recurrent event. The overall incidence density of DVT recurrence was 2.99 per 1000 person-days. The mean ± SD survival time to DVT recurrence was 42.03 ± 22.371 days. Age ≥ 50 years (adjusted hazard ratio [AHR]: 5.566; 95% CI: 1.587-19.518; P = .007), occasional alcohol consumption (AHR: 2.011; 95% CI: 1.307-6.314; P = .019), surgical history (AHR: 6.218; 95% CI: 1.540-25.104; P = .010), pregnancy (AHR: 2.0911; 95% CI: 1.046-4.179; P = .037), diabetes mellitus (AHR: 8.048; 95% CI: 2.494-25.966; P < .001), unmet activated partial thromboplastin time target after 24 hours of heparin (AHR: 1.129; 95% CI: 0.120-10.600; P = .011), proximal site involvement (AHR: 5.937; 95% CI: 1.300-27.110; P = .022), and previous history of DVT (AHR: 2.48; 95% CI: 1.085-11.20; P = .0002) were independent predictors of DVT recurrence. The DVT recurrence rate was high in the study area, which is even complicated with pulmonary embolism as well as death. Efforts are needed to prevent and reduce the development of DVT recurrence.

Effects of time of initiation of antiretroviral therapy in the treatment of patients with HIV/TB co-infection: A systemic review and meta-analysis

This systemic review and meta-analysis aimed to investigate the burden of tuberculosis immune reconstitution syndrome (TB-IRIS) and associated mortality to highlight the importance of future direction in preventing and treatment of TB-IRIS. Randomized clinical trials (RCTs) that compared early antiretroviral therapy (ART) versus late ART were included. PubMed, EMBASE, Science Direct and Cochrane Central Register of Controlled Trials electronic databases were searched. This meta-analysis included 8 RCTs with a total of 4, 425 participants. The result of analysis showed that early initiation of ART was associated with increase in TB-IRIS (RR = 1.83; 95% CI: 1.24-2.70, p = 0.002; I2 = 74%, p = 0.0007) and TB-IRIS associated mortality (RR = 6.05; 95% CI: 1.06-34.59, p = 0.04; I2 = 0%, p = 0.78). Early ART was associated with overall mortality compared with late ART initiation. Grade 3 or 4 adverse events, achieving lower viral load and development of new AIDS-defining illness were not associated with the time of ART initiation. Early ART in HIV/TB co-infected patients resulted conclusive evidence of increased TB-IRIS incidence and TB-IRIS associated mortality. Hence, the finding calls for clinical judgment as to the benefits of initiating ART earlier against the risk of TB-IRIS and associated mortality.

30-day and 60-day rates and predictors of mortality among adult stroke patients: Prospective cohort study

Stroke is one of the most common medical emergencies and the leading cause of preventable death and long-term disability worldwide. A prospective cohort study was conducted at the stroke unit of Jimma university medical center for four consecutive months (from March 10 to July 10, 2017). Of the total 116 study patients, 60 (51.7%) had an ischemic stroke. At 30-day follow-up, 81 (69.8%) patients were alive, 34 (29.3%) were died, and one patient (0.9%) was lost to follow-up. Elevated alanine aminotransferase (ALT) level (AHR: 3.77, 95% CI: 1.34-10.57), diagnosis of stroke clinically alone (AHR: 3.90, 95 CI: 1.49-10.26), brain edema (AHR: 4.28, 95% CI: 1.61-11.37), and National Institute of Health Stroke Scale (NIHSS) ≥ 13 during hospital arrival (AHR: 6.49, 95% CI: 1.90-22.22) were the independent predictors of 30-day mortality. At 60-day follow-up, 68 (58.6%) patients were alive, 46 (39.7%) were died, and 2 (1.7%) were lost to follow-up. Discharge against medical advice (AHR: 6.40, 95% CI: 2.31-17.73) and severe modified Rankin score/mRS (4-5) at discharge (AHR: 3.64, 95% CI: 1.01-13.16) were the independent predictors of 60-day mortality. The median (IQR) length of survival after hospital admission for patients died within 30 and 60 days were 4.65 (2.34-11.80) and 9.3 (3.93-33) days, respectively. Stroke significantly affects the morbidity and mortality in Ethiopia. There is a need to provide better care and future planning for stroke patients as an emergency diagnosis and treatment to minimize mortality and disability.

Health-Related Quality of Life Among People Living with Human Immunodeficiency Virus on Highly Active Antiretroviral Therapy in Ethiopia: PROQOL-HIV Based Survey

Background

As infection with the Human Immunodeficiency Virus (HIV) has evolved into a chronic disease, perceived health-related quality of life (HRQoL) is becoming a prominent and important patient-reported outcome measure in HIV care. This study aimed to assess HRQoL among people living with HIV on highly active antiretroviral therapy and factors associated with HRQoL in Ethiopia.

Methods

An institution-based cross-sectional study was conducted among 160 HIV–infected patients who were initiated highly active antiretroviral therapy at Jimma University Medical Center in 2016. HRQoL was assessed using the patient-reported outcome quality of life-HIV (PROQOL-HIV) measuring scale. Linear regressions were used to identify factors associated with outcome. Statistical significance was considered at p-value <0.05.

Results

Out of a total of 160 participants, 63.13% were females. The mean (±SD) age of study participants was 41.47±9.45 years. The median baseline CD₄+ cell count was 182.00 cells/µL (IQR: 104.53–262.40 cells/µL). The mean (±SD) score of PROQOL-HIV scale domains was 77.58 ±15.11, 58.32 ±7.79, 61.75± 17.95, 85.07 ±15.67, 76.92 ± 20.52, 80.00 ±16.83, 74.37 ± 1.47, 81.45 ± 8.17 for physical health and symptoms, emotional distress, health concerns, body change, intimate relationships, social relationships, stigma, and treatment impact domains, respectively. Second line antiretroviral therapy showed a negative effect on the quality of life, especially on the treatment impact domain (β=−6.301). Cotrimoxazole preventive therapy had a significant positive effect on the physical health and symptoms of HIV patients (β= +8.381, p<0.05). Advanced disease (β=−2.709, p<0.05), and non-communicable disease comorbidity (β=−14.340, p<0.001) showed a significant negative effect on physical health and symptoms.

Conclusion

Several behavioral, clinical & immunological factors were negatively associated with health-related quality of life. The double burden of chronic non-communicable disease(s) and the impact of treatment were highly significant in all dimensions of HRQoL measures. Therefore, with HRQoL emerging as a key issue for HIV–infected patients, its routine assessment and appropriate interventions at each clinic visit would be very crucial.

Risk factors and outcomes of diabetic foot ulcer among diabetes mellitus patients admitted to Nekemte referral hospital, western Ethiopia: Prospective observational study

Objectives

Diabetic foot ulcer is one of the complications of diabetes mellitus. The diabetic patients with foot infections especially gangrene require long-term hospitalization and carry the risk of limb amputation. Despite these challenges, there are a scarce studies done on risk factors and no finding on outcomes of diabetic foot ulcers in Ethiopia.

Patients and methods

A prospective observational study was conducted among diabetes patients with diabetic foot ulcer at Nekemte referral hospital from March 15 to June 15, 2018.

Results

Of the 115 diabetes foot ulcer patients admitted to Nekemte referral hospital, 64(55.65%) were males and the mean age of participants was 44.4 ± 14.7 years. Fifty-eight (50.43%) of the patients had chronic health problems and 56(48.69%) had diabetic complications. Of patients with complications, 35(30.43%) were undergone amputations. Diabetic foot ulcer grade ≥4 (AOR = 1.7; 95% CI: 1.604, 4.789), inappropriate antibiotics use (AOR = 2.526; 95% CI: 1.767, 8.314), overweight (AOR = 2.767; 95% CI: 1.827, 9.252), obesity (AOR = 3.020; 95% CI: 2.556, 16.397), poor blood glucose control (AOR = 2.592; 95% CI: 1.937, 7.168) and neuropathy (AOR = 1.565; 95% CI: 1.508, 4.822) were predictors of amputation up on multivariable logistic regression analysis.

Conclusion

Blood glucose level, higher body mass index, inappropriate antibiotics use, neuropathy and advanced grade of diabetic foot ulcer were independent predictors of amputation. Thus, special emphasis for patients having neuropathy and advanced grade of diabetic foot ulcer as well as weight reduction, managing hyperglycaemia, and appropriate antibiotics prescription practice would decrease untoward effects of diabetic foot ulcer.

•

Foot problems are common in people with diabetes throughout the world, affecting up to 15% of diabetic patients.

•

Diabetic foot complications is the major medical, social and economic problem for all types of diabetes.

•

Advanced diabetes foot infections are the most common diabetes-related cause of hospitalization.

•

Empiric antibiotic regimen is selected for diabetic foot infections on the basis of the likely etiologic agent(s).

•

Peripheral arterial disease (PAD) is present in one-half of all patients with foot ulcers.

Glycemic Control Among People Living with Diabetes and Human Immunodeficiency Virus in Ethiopia: Leveraging Clinical Care for the Looming Co-Epidemics

BACKGROUND

Antiretroviral therapy has decreased human immunodeficiency virus related mortality. However, the incidence of diabetes mellitus is increasing among people living with human immunodeficiency virus and adds complexity to the standards of care.

OBJECTIVE

The study was aimed to determine the glycemic control and delivery of clinical care among people living with diabetes and human immunodeficincy virus in Ethiopia.

METHODS

A comparative prospective cohort study was conducted among patients living with diabetes at follow-up clinics of Jimma Medical Center in two study arms. The first arm was people living with diabetes and human immunodeficiency virus. The second arm was human immunodeficiency virus negative patients living with diabetes. The expanded English version of the summary of diabetes self-care activities scale was used to measure self-care behaviors. In order to identify the predictors of glycemic control, multivariable Cox regression analysis was used. Statistical significance at p-value ≤0.05 was considered.

RESULTS

A total of 297 eligible participants were followed for one year, with a mean age of 44.35±12.55 years. Males accounted for 55.9%. After one year of follow-up, 61.9% of diabetes people living with human immunodeficiency virus, and 49% of human immunodeficiency virus-negative patients with diabetes poorly met blood glucose target (p=0.037). Female gender [AHR: 2.72; 95% CI (1.21-5.72)], age >31 years [AHR: 2.48; 95% CI (1.34-11.01)], increased waist circumference [AHR: 3.64; 95% CI (2.57-16.12)], overweight [AHR: 3.63; 95% CI (1.65-22.42)], chronic disease comorbidity [AHR: 2.02; 95% CI (1.44-2.84)], human immunodeficiency virus infection [AHR: 3.47; 95% CI (2.03-23.75)], living longer with diabetes (>5 years) [AHR: 3.67; 95% CI (3.26-4.14)] showed a higher risk of blood sugar control failure and were independent predictors of uncontrolled glycemia. Tuberculosis infection increased the risk of uncontrolled blood sugar among people living with diabetes and human immunodeficency virus[AHR:3.82;95% CI(2.86-5.84].

CONCLUSION

Significant gaps were observed in achieving the recommended glycemic target and involvement of patients on self-care care behavior in the study area. The co-occurrence of tuberculosis, human immunodeficiency virus, and diabetes is triple trouble needing special attention in their management. It is high time to leverage the clinical care of the looming co-epidemics through chronic comprehensive care clinic.

Risk factors, clinical presentations and predictors of stroke among adult patients admitted to stroke unit of Jimma university medical center, south west Ethiopia: prospective observational study

Background

Stroke is the second-leading global cause of death behind heart disease in 2013 and is a major cause of permanent disability. The burden of stroke in terms of mortality, morbidity and disability is increasing across the world. It is currently observed to be one of the commonest reasons of admission in many health care setups and becoming an alarming serious public health problem in our country Ethiopia. Despite the high burden of strokes globally, there is insufficient information on the current clinical profile of stroke in low and middle income countries (LMICs) including Ethiopia. So, this study was aimed to assess risk factors, clinical presentations and predictors of stroke subtypes among adult patients admitted to stroke unit of Jimma university medical center (JUMC).

Methods

Prospective observational study design was carried out at stroke unit (SU) of JUMC for 4 consecutive months from March 10–July 10, 2017. A standardized data extraction checklist and patient interview was used to collect data. Data was entered into Epi data version 3.1 and analyzed using SPSS version 20. Multivariable logistic regression was used to identify the predictors of stroke subtypes.

Result

A total of 116 eligible stroke patients were recruited during the study period. The mean age of the patients was 55.1 ± 14.0 years and males comprised 62.9%. According to world health organization (WHO) criteria of stroke diagnosis, 51.7% of patients had ischemic while 48.3% had hemorrhagic stroke. The most common risk factor identified was hypertension (75.9%) followed by family history (33.6%), alcohol intake (22.4%), smoking (17.2%) and heart failure (17.2%). The most common clinical presentation was headache complained by 75.0% of the patients followed by aphasia 60.3% and hemiparesis 53.4%. Atrial fibrillation was the independent predictor of hemorrhagic stroke (AOR: 0.08, 95% CI: 0.01–0.68).

Conclusion

The clinical characteristics of stroke in this set up were similar to other low- and middle-resource countries. As stroke is a high priority chronic disease, large-scale public health campaign should be launched focusing on public education regarding stroke risk factors and necessary interventions.

Immunologic Restoration of People Living with Human Immunodeficiency Virus on Highly Active Anti-retroviral Therapy in Ethiopia: The Focus of Chronic Non-Communicable Disease Co-Morbidities

Background:

The life expectancy of people living with Human Immunodeficiency Virus (HIV) has dramatically improved with the much-increased access to antiretroviral therapy. Consequently, a larger number of people living with HIV are living longer and facing the increased burden of non-communicable diseases. This study assessed the effect of chronic non-communicable disease(s) and co-morbidities on the immunologic restoration of HIV infected patients on highly active antiretroviral therapy.

Methods:

A nested case-control study was conducted among people living with HIV at Jimma University Medical Center from February 20 to August 20, 2016. Cases were HIV infected patients living with chronic non-communicable diseases and controls were people living with HIV only. Patient-specific data were collected using a structured data collection tool to identify relevant information. Data were analyzed using the Statistical Package for Social Science version 20.0. Logistic regressions were used to identify factors associated with outcome. Statistical significance was considered at p-value <0.05. A patient's written informed consent was obtained after explaining the purpose of the study.

Results:

A total of 240 participants (120 cases and 120 controls) were included in the analysis. Prevalence of hypertension was 12.50%, and diabetes was 10.84%. About 10.42% of study participants were living with multi-morbidity. At baseline, the mean (±SD) age of cases was 42.32±10.69 years, whereas it was 38.41±8.23 years among controls. The median baseline CD4+ cell count was 184.50 cells/µL (IQR: 98.50 - 284.00 cells/µL) for cases and 177.0 cells/µL (IQR: 103.75 - 257.25 cells/µL) for controls. Post-6-months of highly active antiretroviral therapy initiation, about 29.17% of cases and 16.67% of controls had poor immunologic restoration. An average increase of CD4+ cell count was 6.4cells/µL per month among cases and 7.6 cells/µL per month among controls. Male sex [AOR, 3.51; 95% CI, 1.496 to 8.24; p=0.004], smoking history [AOR, 2.81; 95% CI, 1.072, to 7.342; p=0.036] and co-morbidity with chronic non-communicable disease(s) [AOR, 3.99; 95% CI, 1.604 to 9.916; p=0.003)] were independent predictors of poor immunologic restoration.

Conclusions:

Chronic non-communicable disease(s) have negative effects on the kinetics of CD4+ cell count among HIV-infected patients who initiated antiretroviral therapy. So the integration of chronic non-communicable disease-HIV collaborative activities will strengthen battle to control the double burden of chronic illnesses.

Patterns and epidemiology of acute poisoning in Ethiopia: systematic review of observational studies

BACKGROUND

Acute poisoning is a common reason for emergency department visit and hospitalization worldwide with major morbidity and mortality. The burden of poisoning exposures in Africa is a significant public health concern, but only 10 of 58 countries have poisons information centers (PICs).

OBJECTIVE

The primary intention of our current review is to explore and summarize the published evidence on the patterns and epidemiology of poisoning in Ethiopia.

METHOD

PubMed and Scopus were searched for primary, case series and human studies for publications from inception to July 2017. A manual search for additional relevant studies using references from retrieved articles was also performed. Only studies that reported acute poisoning in both pediatric and adult patients were included. From the screened articles, data were extracted for baseline characteristics and relevant end points such as case fatality rate, time for health institution presentation and length of hospital stay.

RESULT

Initial entry and search resulted in the retrieval of 332 articles. Finally, 9 studies comprised of 4763 participants were included in this current review. In 78% of the studies included in this review, acute poisoning is reported to be more prevalent in females. Acute poisoning was revealed to be prevalent in less than 30 years old. Organophosphates and household cleaning agents were the predominant agents of acute poisoning. Intentional poisoning was identified responsible for the majority of acute poisoning cases and factors such as psychiatric problems, and quarrel were identified as the underlying reasons for poisoning. Time of presentation to health institution after poisoning, length of hospital stay and case fatality rate were reported and lies in the ranges between 0.2 h-24 h, 0.5 days-17.7 days and 0-14.8%, respectively.

CONCLUSION

The occurrence of acute poisoning was higher in females and common in less than 30 years of age, making this a real public health burden in Ethiopia. Psychiatric problems, quarrel and substance abuse were identified as the most common reasons for acute poisoning. Awareness creation how to handle chemicals and prescribed drugs and psychiatric consultations should be in place for the community.

Blood pressure control and its determinants among diabetes mellitus co-morbid hypertensive patients at Jimma University medical center, South West Ethiopia

Background

Hypertension is the major contributor to cardiovascular diseases related morbidity and mortality. Blood pressure is not well controlled in the majority of patients with both diabetes and hypertension. The main objective of this study was to assess blood pressure control and its determinants among diabetes mellitus co- morbid hypertensive ambulatory patients.

Methods

Hospital based cross sectional study was conducted among diabetes mellitus co-morbid hypertensive ambulatory adult patients based on the inclusion criteria. Patient specific data was collected using structured data collection tool. Data was analyzed using statistical software package, SPSS version 20.0. To identify the independent predictors of blood pressure control, multiple stepwise backward logistic regression analysis was done. Statistical significance was considered at p-value <0.05. Patient’s written informed consent was obtained after explaining the purpose of the study. Patients were informed about confidentiality of the information obtained.

Results

From a total of 131 study participants 51.14% were males with the mean (SD) age of the 50.69 ± 13.71. The mean duration of time since the diagnosis of hypertension was 7.44 ± 5.11 years. The mean (SD) SBP was 149.79 ± 16.32 mmHg, while the mean (SD) DBP was 89.77 ± 9.34 mmHg. More than one fourth (25.20%) of study participants had a controlled SBP, while about 27.48% had a controlled DBP. The overall control of BP was achieved in about 57 (43.51%) of the study participants. Older age (≥50 years) (AOR = 2.06; 95% CI: 2.65–7.79; P = 0.002), female gender (AOR = 1.42; 95% CI: 1.19–2.14; P = 0.042), duration of hypertension (AOR = 2.88, 95% CI: 1.27, 8.31, P = 0.02), non-adherence (AOR 2.05; 95% CI: 2.61–9.33; P = 0.01) and uncontrolled blood sugar(AOR = 1.65; 95% CI: 2.14–3.32; P = 0.04) are independent predictors for uncontrolled blood pressure.

Conclusions

Blood pressure control to target goal was suboptimal in the study area. Diabetic patients who were older, female, live longer duration with hypertension, non-adherent to their medications and poor glycemic control were more likely to have uncontrolled BP. Therefore, more effort should be dedicated to control the blood pressure in diabetics.

The Effect of High-dose Parenteral Sodium Selenite in Critically Ill Patients following Sepsis: A Clinical and Mechanistic Study

INTRODUCTION

Severe sepsis and septic shock is characterized by inflammation and oxidative stress. Selenium levels have been reported to be low due to loss or increased requirements during severe sepsis and septic shock. We investigated the effect of high-dose parenteral selenium administration in septic patients.

METHODS

A prospective, randomized control clinical trial was performed in septic patients. After randomization, patients in selenium group received high-dose parenteral sodium selenite (2 mg intravenous [IV] bolus followed by 1.5 mg IV continuous infusion daily for 14 days) plus standard therapy and the control group received standard therapy. The primary endpoint was mortality at 28 days. Changes in the mean levels of high mobility group box-1 (HMGB-1) protein and superoxide dismutase (SOD), duration of vasopressor therapy, incidence of acute renal failure, and 60 days' mortality were secondary endpoints.

RESULTS

Fifty-four patients were randomized into selenium group (n = 29) and control group (n = 25). There was no significant difference in 28-day mortality. No significant difference between the two groups with respect to the average levels of HMGB-1 protein and SOD at any point in time over the course of 14 days had observed.

CONCLUSION

In early administration within the first 6 h of sepsis diagnosis, our study demonstrated that high-dose parenteral selenium administration had no significant effect either on 28-day mortality or the mean levels of HMGB-1 and SOD (Trial Registration: IRCT201212082887N4 at WHO Clinical Trial Registry, August 29, 2014).

Olanzapine for chemotherapy-induced nausea and vomiting: systematic review and meta-analysis

Background:

Chemotherapy induced nausea and vomiting (CINV) remains the most distressing event in patients receiving highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC).

Objective:

Therefore, this meta-analysis was conducted to evaluate the efficacy of olanzapine containing regimen in preventing acute, delayed and overall phases of CINV.

Methods:

PubMed, EBSCO, and Cochrane central register of controlled trials electronic databases were searched to identify RCTs that compared the effects of olanzapine with non-olanzapine regimen in preventing CINV. Randomized clinical trials (RCTs) that compared olanzapine containing regimen with non-olanzapine regimen were included. The primary outcomes were the percentage of patients achieving no vomiting or no nausea in acute, delayed and overall phases.

Results:

13 RCTs that enrolled 1686 participants were included in this meta-analysis. 852 patients were assigned to olanzapine and 834 patients were assigned to non-olanzapine regimen (other standard antiemetic regimen). The percentages of no emesis achieved were 87.5%, 76.2%, 73.6% in olanzapine versus 76.7%, 61.8%, and 56.4% in non-olanzapine regimen in acute, delayed and overall phases, respectively. The percentages of no nausea were 82%, 64.3%, 61.6% in olanzapine group versus 71.3%, 41.8%, and 40.6% in non-olanzapine group in acute, delayed and overall phases, respectively. In general, olanzapine containing regimen achieved statistical superiority to non-olanzapine regimen in no vomiting endpoint in acute phase (OR 2.16; 95%CI 1.60 to 2.91, p<0.00001; I-square=5%; p=0.40), delayed phase (OR 2.28; 95%CI 1.1.46 to 3.54, p=0.0003; I-square=65%; p=0.001) and overall phase (OR 2.48; 95%CI 1.59 to 3.86, p<0.0001; I-square=69%; p< 0.0001).

Conclusion:

The current meta-analysis showed that olanzapine was statistically and clinically superior to non-olanzapine regimen in preventing CINV in most domains of the parameters.

Effect of Calories Delivered on Clinical Outcomes in Critically Ill Patients: Systemic Review and Meta-analysis

Introduction:

International guidelines are promoting early enteral nutrition (EN) as a means of feeding critically ill adult patients to improve clinical outcomes. The question of how much calorie intake is enough to improve the outcomes still remained inconclusive. Therefore, we carried out a meta-analysis to evaluate the effect of low calorie (LC) versus high calorie (HC) delivery on critically ill patients' outcomes.

Methods:

We included randomized clinical trials (RCTs) that compared LC EN with or without supplemental parenteral nutrition with HC delivery in this meta-analysis irrespective of the site of nutritional delivery in the gastrointestinal tract. We searched PubMed, EMBASE, and Cochrane central register of controlled trials electronic databases to identify RCTs that compared the effects of initially different calorie intake in critical illness. The primary outcome was overall mortality.

Results:

This meta-analysis included 17 RCTs with a total of 3,593 participants. The result of analysis showed that there was no significant difference between the LC group and HC group in overall mortality (risk ratio [RR], 0.98; 95% confidence interval [CI], 0.87–1.10; P = 0.74; I² = 6%; P = 0.38), or new-onset pneumonia (RR, 0.92; 95% CI, 0.73–1.16, P = 0.46; I² = 38%, P = 0. 11).

Conclusion:

The current meta-analysis showed that there was no significant difference in mortality of critically ill patients initially between the two groups.

Intestinal polyparasitism with special emphasis to soil-transmitted helminths among residents around Gilgel Gibe Dam, Southwest Ethiopia: a community based survey

BACKGROUND

One third of the world population is estimated to be infected with intestinal parasites. The most affected people are children and the poor people living in tropics and subtropics. Polyparasitism (the concurrent infection with multiple intestinal parasite species) is found to be the norm among the same population although accurate estimate of its magnitude is unknown. It was found that polyparasitism might have a greater impact on morbidity than single species infection which might also increase susceptibility to other infections. Therefore, this study aimed at determining the prevalence and distribution of intestinal polyparasitism with special emphasis on Soil-Transmitted Helminths (STH) among residents around Gilgel Gibe dam located in Jimma zone of Oromia regional state, Ethiopia.

METHODS

A total of 1,021 participants were recruited in this study and provided stool samples for parasitological examination. Direct wet mount and Kato-Katz techniques were employed for stool examination. Pearson chi-square test was employed to assess the association of infection status and polyparasitism with gender and age group of the study participants.

RESULTS

Five hundred thirty two individuals were infected with at least one parasite, providing the overall prevalence of 52.1%. Among positive individuals, 405 (76.1%), 114 (21.4%), and 13 (2.5%) individuals were infected with only one, two and three species of parasites, respectively. The overall prevalence of intestinal polyparasitism observed among the study participants was 12.4% (127/1,021). The predominant STH was hookworm, with a prevalence of 44.1%. Hookworm and Ascaris lumbricoides were the most frequently recorded combination in cases of polyparasitic infection. The study revealed that there was no significant difference in the distribution of polyparasitism with regard to age group and sex of the study participants (p > 0.05).

CONCLUSION

The study indicated the presence of high prevalence of parasites as well as distribution of polyparasitism in the area. Moreover, the detection of Schistosoma mansoni in the community living within close proximity of the newly constructed dam would be taken as an indication of future risk factor. Further investigation on the predictors of polyparasitism and the assessment of effects of polyparasitism on the population are needed. Finally, there is a need to undertake integrated control strategies which involve improved sanitation, health education and chemotherapy that targets the whole community instead of only certain segments of populations.

The effect of parenteral selenium on outcomes of mechanically ventilated patients following sepsis: a prospective randomized clinical trial

Background

Sepsis and septic shock is characterized by oxidative stress that mainly promotes systemic inflammation and organ failure due to excessive free radical production and depletion of antioxidant defenses. Therefore, we investigated the effect of selenium administration on antioxidant status, levels of cytokines and clinical outcomes.

Methodology

This study was a prospective randomized control trial (RCT) whereby patients received selenium as sodium selenite (2 mg IV bolus followed by 1.5 mg continuous infusion for 14 days) plus standard therapy. The control group received standard therapy without selenium. The primary endpoint was 28-day mortality. The changes in the mean levels of glutathione peroxidase (GPX) activity, IL-6, IL-8 and IL-10, the incidence of ventilator-associated pneumonia (VAP) and other secondary endpoints were also recorded. VAP was broken down into early VAP and late VAP to see the clinical significance of each. We also recorded any adverse outcomes from selenium infusion.

Results

Over 24-month period, 54 patients were recruited and randomized and an intention to treat (ITT) principle was applied (selenium, n = 29; control, n = 25) in the final analysis. There was no statistically significant difference between the two groups in 28-day mortality although it was lower in the selenium group compared with the control group: 9 (31 %) in the selenium versus 10 (40 %) in the control groups (p = 0.49). At day 0, GPX activity was 0.185 ± 0.3 versus 0.19 ± 0.3 U/mL (p = 0.9), day 3, GPX activity was 0.52 ± 0.5 versus 0.17 ± 0.2 U/mL (p = 0.02), at day 7 it was 0.55 ± 0.5 versus 0.24 ± 0.3 U/mL (p = 0.032), at day 10 it was 0.62 ± 0.7 versus 0.33 ± 0.4 U/mL (p = 0.048) and at day 14 it was 1.1 ± 1 versus 0.89 ± 1 U/mL (p = 0.70) for the selenium versus control groups, respectively. However, there were no significant differences between the mean plasma levels of all the three inflammatory cytokines at any point in time between the two groups. There was a significant reduction in occurrence of VAP in the selenium group compared with the control group (55.2 versus 84 %, p = 0.023), respectively.

Conclusion

High-dose selenium administration within the time frame of early goal-directed therapy was not resulted in reduction of 28-day mortality, but increased the activity of glutathione peroxidase with no effect on the levels of inflammatory cytokines at any point in time in mechanically ventilated septic patients. However, selenium supplementation in mechanically ventilated patients following sepsis was associated with reduced occurrence of VAP.

Early goal-directed therapy reduces mortality in adult patients with severe sepsis and septic shock: Systematic review and meta-analysis

Introduction:

Survival sepsis campaign guidelines have promoted early goal-directed therapy (EGDT) as a means for reduction of mortality. On the other hand, there were conflicting results coming out of recently published meta-analyses on mortality benefits of EGDT in patients with severe sepsis and septic shock. On top of that, the findings of three recently done randomized clinical trials (RCTs) showed no survival benefit by employing EGDT compared to usual care. Therefore, we aimed to do a meta-analysis to evaluate the effect of EGDT on mortality in severe sepsis and septic shock patients.

Methodology:

We included RCTs that compared EGDT with usual care in our meta-analysis. We searched in Hinari, PubMed, EMBASE, and Cochrane central register of controlled trials electronic databases and other articles manually from lists of references of extracted articles. Our primary end point was overall mortality.

Results:

A total of nine trails comprising 4783 patients included in our analysis. We found that EGDT significantly reduced mortality in a random-effect model (RR, 0.86; 95% confidence interval [CI], 0.72–0.94; P = 0.008;   I² =50%). We also did subgroup analysis stratifying the studies by the socioeconomic status of the country where studies were conducted, risk of bias, the number of sites where the trials were conducted, setting of trials, publication year, and sample size. Accordingly, trials carried out in low to middle economic income countries (RR, 0.078; 95% CI, 0.67–0.91; P = 0.002; I² = 34%) significantly reduced mortality compared to those in higher income countries (RR, 0.93; 95% CI, 0.33–1.06; P = 0.28; I² = 29%). On the other hand, patients receiving EGDT had longer length of hospital stay compared to the usual care (mean difference, 0.49; 95% CI, –0.04–1.02; P = 0.07; I² = 0%).

Conclusion:

The result of our study showed that EGDT significantly reduced mortality in patients with severe sepsis and septic shock. Paradoxically, EGDT increased the length of hospital stay compared to usual routine care.

Comparison of anti-retroviral therapy treatment strategies in prevention of mother-to-child transmission in a teaching hospital in Ethiopia

Background:

More than 90% of Human immunodeficiency virus (HIV) infection in children is acquired due to mother-to-child transmission, which is spreading during pregnancy, delivery or breastfeeding.

Objective:

To determine the effectiveness of highly active antiretroviral and short course antiretroviral regimens in prevention of mother-to-child transmission of HIV and associated factors Jimma University Specialized Hospital (JUSH).

Method:

A hospital based retrospective cohort study was conducted on HIV infected pregnant mothers who gave birth and had follow up at anti-retroviral therapy (ART) clinic for at least 6 months during a time period paired with their infants. The primary and secondary outcomes were rate of infant infection by HIV at 6 weeks and 6 months respectively. The Chi-square was used for the comparison of categorical data multivariate logistic regression model was used to identify the determinants of early mother-to-child transmission of HIV at 6 weeks. Cox proportional hazard model was used to analyze factors that affect the 6 month HIV free survival of infants born to HIV infected mothers.

Results:

A total of 180 mother infant pairs were considered for the final analysis, 90(50%) mothers received single dose nevirapine (sdNVP) designated as regimen-3, 67 (37.2%) mothers were on different types of ARV regimens commonly AZT + 3TC + NVP (regimen-1), while the rest 23 (12.8%) mothers were on short course dual regimen AZT + 3TC + sdNVP (regimen-2). Early mother-to-child transmission rate at 6 weeks for regimens 1, 2 and 3 were 5.9% (4/67), 8.6% (2/23), and 15.5% (14/90) respectively. The late cumulative mother-to-child transmission rate of HIV at 6 months regardless of regimen type was 15.5% (28/180). Postnatal transmission at 6 months was 28.5% (8/28) of infected children. Factors that were found to be associated with high risk of early mother-to-child transmission of HIV include duration of ARV regimen shorter than 2 months during pregnancy (OR=4.3, 95%CI =1.38-13.46), base line CD4 less than 350 cells/cubic mm (OR=6.98, 95%CI=0.91-53.76), early infant infection (OR=5.4, 95%CI=2.04-14.4), infants delivered home (OR=13.1, 95%CI=2.69-63.7), infant with birth weight less than 2500 g (OR=6.41, 95%CI=2.21-18.61), and mixed infant feeding (OR=6.7, 95%CI=2.2-20.4). Antiretroviral regimen duration less than 2 months, maternal base line CD4 less than 350 cells/cubic mm and mixed infant feeding were also important risk factors for late infant infection or death.

Conclusion:

The effectiveness of multiple antiretroviral drugs in prevention of early mother-to-child transmission of HIV was found to be more effective than that of single dose nevirapine, although, the difference was not statistically significant. But in late transmission, a significant difference was observed in which infants born to mother who received multiple antiretroviral drugs were less likely to progress to infection or death than infants born to mothers who received single dose nevirapine.

The immunological benefit of higher dose N-acetyl cysteine following mechanical ventilation in critically ill patients

BACKGROUND

Sepsis complication is a major cause of death in multiple trauma critically ill patients. Defensin (cysteine rich anti-microbial peptides), as an important component of immune system, might play an important role in this process. There is also rising data on immunological effects of N-acetyl-cysteine (NAC), a commonly used anti-oxidant in oxidative stress conditions and glutathione (GSH) deficiencies. The aim of the present study was to evaluate the potential beneficial effects of NAC administration on multiple trauma patients with sepsis.

METHODS

In a prospective, randomized controlled study, 44 multiple trauma critically ill patients who were mechanically ventilated and met the criteria of sepsis and admitted to the intensive care unit (ICU) were randomized into two groups . Control group received all standard ICU therapies and NAC group received intravenous NAC 3 gr every 6 hours for 72 hours in addition to standard therapies. Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores, length of ICU stay, ICU mortality were recorded. Levels of serum Immunoglobulin M (IgM), Human β-Defensin 2 (HβD2) and GSH were assessed at baseline and 24, 72, 120 hours after intervention.

RESULTS

During a period of 13-month screening, 44 patients underwent randomization but 5 patients had to be excluded. 21 patients in NAC group and 18 patients in control group completed the study. For both groups the length of ICU stay, SOFA score and systemic oxygenation were similar. Mortality rate (40% vs. 22% respectively, p = 0.209) and ventilator days (Mean ± SD 19.82 ± 19.55 days vs. 13.82 ± 11.89 days respectively, p = 0.266) were slightly higher for NAC group. IgM and GSH levels were similar between two groups (p = 0.325, 0.125 respectively), HβD2 levels were higher for NAC group (at day 3).

CONCLUSION

High dose of NAC administration not only did not improve patients' outcome, but also raised the risk of inflammation and was associated with increased serum creatinine.
