Substance Use and Sexually Transmitted Infections Among Anti-Retroviral Treatment Attendees in Jimma University Specialized Hospital,Jimma, Ethiopia

Background

Substance use increases both the risk of Human Immunodeficiency Virus and other Sexually Transmitted Infections, either directly or indirectly. The association of substance use and Sexually Transmitted Infections has not yet studied in Southwestern Ethiopia. The main aim of this study is to determine the associations between substance use and Sexually Transmitted Infections on clients under follow up in Anti-Retroviral Treatment clinic at Jimma University Specialized Hospital.

Methods

A cross-sectional study was conducted on clients under follow up at Anti-Retroviral Treatment clinic from June 10 to July 10, 2011 at Jimma University Specialized Hospital. Data collection was done using a pre-coded and pre-tested questionnaire. Trained Anti-Retroviral Treatment adherence counselors collected the data. Data were entered and analyzed using SPSS for Windows version 16.0. Chi-square test was used to measure the levels of significance. P-value < 0.05 was considered as significant.

Results

Three hundred thirty eight Anti-Retroviral Treatment attendees participated in the study. Two hundred twenty (65.1%) of the study participants were females and their mean (±SD) age was 33.6 ± 8.04 years while 156 (46.2%) of them lied in the age group of 25–34 years. Clients who reported that they had Sexually Transmitted Infections were 120 (35.5%). Those who consumed alcohol were more likely to have contracted in Sexually Transmitted Infections: AOR (95% CI) =0.46 (0.26–0.80).

Conclusion

Prevalence of Sexually Transmitted Infections was comparable among females and males. Substance use, particularly alcohol consumption, found to be a potential risk factor for Sexually Transmitted Infections.     

Quality of life,socioeconomic profile,knowledge and attitude toward sexuality from the perspectives of individuals living with Human Immunodeficiency Virus

Objectives:

to analyze the quality of life of "patients" with Human Immunodeficiency Virus and relate it to their socioeconomic profile, knowledge and attitudes toward sexuality.

Method:

crosssectional and analytical study with 201 individuals who are 50 years old or older. The Targeted Quality of Life and Aging Sexual Knowledge and Attitudes Scales were applied during interviews. Multiple Linear Regression was used in data analysis.

Results:

dimensions of quality of life more strongly compromised were disclosure worries (39.0), sexual function (45.9), and financial worries (55.6). Scores concerning knowledge and attitudes toward sexuality were 31.7 and 14.8, respectively. There was significant correlation between attitudes and the domains of overall function, health worries, medication worries, and HIV mastery.

Conclusion:

guidance concerning how the disease is transmitted, treated and how it progresses, in addition to providing social and psychological support, could minimize the negative effects of the disease on the quality of life of patients living with the Human Immunodeficiency Virus.     

Acute Loss of Vision in a Young Woman: A Case Report on Psychogenic Blindness

Background

Acute loss of vision needs urgent attention and treatment. We report on a young Ethiopian woman who experienced acute bilateral blindness. In the presence of normal ophthalmological findings psychogenic blindness has to be considered.

Case Details

A 21 years old woman was admitted to the psychiatry clinic at Jimma University specialized Hospital, Jimma, South West Ethiopia. She had not been able to see for a few days. Ophthalmological and neurological examinations showed normal findings. No severe psychopathology was found. Stressful life events had preceded the appearance of the symptoms. An attitude of accepting the perspective of the patient of a seemingly organic disease is a precondition for a successful intervention. Treatment aimed at a gradual return to normal functioning. The patient regained her sight and fully recovered. The final psychiatric diagnosis was psychogenic blindness.

Conclusion

The psychosocial intervention was successful and encouraging for the patient and clinicians.     

Hepatotoxicity and Associated Risk Factors in HIV-Infected Patients Receiving Antiretroviral Therapy at Felege Hiwot Referral Hospital,Bahirdar, Ethiopia

Background

In Human Immunodeficiency Virus (HIV) infected patients on antiretroviral treatment (ART), hepatotoxicity is life threatening. Its outcome may lead to liver failure and death. This study was conducted to determine the rate and determinants of elevated alanine amino transferase (ALT) (referred as >40IU/L for both males and females).

Methods

A cross sectional study was conducted on HIV infected individuals who are on ART and suspected of drug resistance at Felege Hiwot Referral Hospital, Bahir Dar from July to December 2012. Venous bloods were collected from each patient and processed parallely to determine ALT, number of HIV RNAs, CD4 and CD8 T cells count, anti hepatitis C virus (HCV) and hepatitis B surface antigen.

Results

Out of 269 HIV infected patients receiving ART, 32% were confirmed of grades 1–4 levels of elevated ALT. The rate of severe hepatotoxicity (grade 3 and 4) was 1.84%. Patients with increased CD8 T cell counts (P=0.011; AOR=1.82; CI: 1.12 –2.54), alcohol over use (P=0.014; AOR = 1.23; CI: 1.36–3.29) and detectable HIV-1 RNA copies (P=0.015; AOR=2.07; CI: 1.15–3.74) independently predicts the elevation of ALT.

Conclusions

In HIV infected patients on ART, extreme elevations of ALT were infrequent but minor elevations were common so that patient-linked variables such as use of alcohol intake must be taken in to account for better clinical management of ART patients. The role of active HCV co-infection on the treatment outcome of ART should be further studied.     

Prevalence and predictors of intestinal helminthiasis among school children in jimma zone; a cross-sectional study

Background

Globally, millions of people suffer from intestinal parasitic infections. These infections are among the most common resulting in considerable morbidity and mortality. In Ethiopia and particularly in Jimma and its surroundings intestinal parasitic infections are highly prevalent because of low living standards and poor environmental sanitation. The objective of the survey was to determine the prevalence and predictors of intestinal parasitosis among school children in four woredas of Jimma zone surrounding Gilgel gibe hydraulic dam and serve as a base line data to help evaluate health promoting activities for the future and monitor those already delivered to the community.

Methods

A cross-sectional study was carried out in October, 2008 in four Woredas of Jimma zone bordering Gilgel Gibe Dam. Children attending grades 1–8 in the schools located within 10 Kms ofthe Dam in the four bordering woredas and those living 30 Kms away from the shore line were the study subjects. Six hundred twenty four and 321 children were selected from the schools around Gilgel Gibe dam and from the schools in Bulbul, respectively. Data on background of participant was collected and stool specimen collected and processed. Data were filtered and entered into computer then analyzed using SPSS for windows version 13.0.1.

Results

Of the 937 selected individuals, 855 participated in the study giving a response rate of 91.2%. The prevalence of intestinal parasitosis was 47.1% where 174 (20%) had Ascaris lumbricoides monoinfection; 4.3% had dual infection involving Ascaris lumbricoides and hookworm and 0.2% had triple infection but all the infections were of light intensity. In addition, there was no association between prevalence of intestinal parasitosis with availability or regular use of latrine and clinical symptoms.

Conclusion

The prevalence and intensity of intestinal parasites in the study area is lower than national, urban and rural setting of Jimma zone. These might be due to a better awareness of the study community on prevention of intestinal parasitosis following increased health promoting activities in the area, delivered through various activities of Jimma Public health training program.     

Empathy Without Borders? Cross-Cultural Heart and Mind-Reading in First-Year Medical Students

Background

This cross-cultural study was designed to examine cultural differences in empathy levels of first-year medical students.

Methods

A total of 257 students from the academic year 2010/11, 131 at Jimma University, Ethiopia, and 126 at the Ludwig Maximilian University, Munich, Germany, completed the Balanced Emotional Empathy Scale (BEES), the Reading the Mind in the Eyes (RME-R) test, and a questionnaire on sociodemographic and cultural characteristics. Furthermore, we conducted a qualitative analysis of the students'' personal views on the definition of empathy and possible influencing factors. Group comparisons and correlation analyses of empathy scores were performed for the entire cohort and for the Jimma and Munich students separately. We used a regression tree analysis to identify factors influencing the BEES.

Results

The male students in Jimma (39.1 ± 22.3) scored significantly higher in the BEES than those male students from Munich (27.2 ± 22.6; p = 0.0002). There was no significant difference between the female groups. We found a moderate, positive correlation between the BEES and RME-R test, i.e. between emotional and cognitive empathy, within each university. Nevertheless, the RME-R test, which shows only Caucasian eyes, appears not to be suitable for use in other cultures.

Conclusions

The main findings of our study were the influence of culture, religion, specialization choice, and gender on emotional empathy (assessed with the BEES) and cognitive empathy (assessed with the RME-R test) in first-year medical students. Further research is required into the nature of empathy in worldwide medical curricula.     

The quality of care provided to patients with chronic non-communicable diseases: a retrospective multi-setup study in jimma zone, southwest ethiopia

Background

Chronic Non-Communicable Diseases are among the major causes of morbidity and mortality worldwide. However, access to and quality of health care for patients is very low in developing countries including Ethiopia. Hospitals and Health Centers are the main sources of health care for such patients in Ethiopia. In this study we assessed the quality of care patients with Chronic Non-Communicable Diseases received in hospital and health center setups.

Methods

A retrospective multi-setup study was conducted in Jimma University Specialized Hospital and four Health Centers in Jimma Zone from February to March 2010. A total of 52 process indicators of quality covering three disease conditions: Diabetes, Hypertension and Epilepsy were measured by reviewing randomly selected medical records. Quality of care was measured as a proportion of recommended components of care actually provided to patients. And also outcome and structural measures were assessed to supplement process measures of quality.

Results

Six hundred seventy four medical records were reviewed. Recommended care components were actually provided to patients in 35.1% (95% CI:34.1%, 36.0%), 38.5% (95% CI:37.5%, 39.5%) and 60.1% (95% CI:59.3%, 61.0%) of times on which patients were eligible, among patients with Diabetes, Hypertension and Epilepsy, respectively. After case mix adjustment, it was found that 45.9% (95% CI:45.4%, 46.5%) of recommended components of care was actually provided to patients. This was 45.1% (95% CI:44.4%, 45.8%) in the hospital and 30.5% (95% CI:29.7%, 31.3%) in the health centers. Among patients for whom outcome data was available, optimal level of disease control was achieved only for 47 (30.5%), 40 (38.5%) and 193 (52.9%) of patients with Diabetes, Hypertension and Epilepsy, respectively.

Conclusion

The quality of care provided to patients with Chronic Non-Communicable Diseases is very low in both settings though it is relatively better in Jimma University Specialized Hospital. Therefore, a continuous process of quality improvement is recommended in both settings.     

Khat chewing and mental distress: a community based study, in jimma city, southwestern ethiopia

Background

Khat (Catha edulis) contains a psychoactive substance, cathinone, which produces central nervous system stimulation analogous to amphetamine. It is believed that khat chewing has a negative impact on the physical and mental health of individuals as well as the socioeconomic condition of the family and the society at large. There is lack of community based studies regarding the link between khat use and poor mental health. The objective of this study was to evaluate the association between khat use and mental distress and to determine the prevalence of mental distress and khat use in Jimma City.

Methods

A cross-sectional community-based study was conducted in Jimma City from October 15 to November 15, 2009. The study used a structured questionnaire and Self Reporting Questionnaire-20 designed by WHO and which has been translated into Amharic and validated in Ethiopia. By multi stage sampling, 1200 individuals were included in the study. Data analysis was done using SPSS for window version 13.

Results

The Khat use prevalence was found to be 37.8% during the study period. Majority of the khat users were males (73.5%), age group 18–24 (41.1%), Muslims (46.6%), Oromo Ethnic group (47.2%), single (51.4%), high school students (46.8%) and employed (80%). Using cut-off point 7 out of 20 on the Self Reporting Questionnaire-20, 25.8% of the study population was found to have mental distress. Males (26.6%), persons older than 55 years (36.4%), Orthodox Christians (28.4%), Kefficho Ethnic groups (36.4%), widowed (44.8%), illiterates (43.8%) and farmers (40.0%) had higher rates of mental distress. We found that mental distress and khat use have significant association (34.7% Vs 20.5%, P<0.001). There was also significant association between mental distress and frequency of khat use (41% Vs 31.1%, P<0.001)

Conclusion

The high rate of khat use among the young persons calls for public intervention to prevent more serious forms of substance use disorders. Our findings suggest that persons who use khat suffer from higher rates of mental distress. However, causal association could not be established due to cross-sectional study design.     

Evaluation of an Antigen-Antibody “Combination” Enzyme Linked Immunosorbent Assay for Diagnosis of Hepatitis C Virus Infections

Background

Development of “combination” assays detecting in parallel, within a single test, Hepatitis C Virus (HCV) antigens and antibodies, not only reduces the window period in HCV-infection but also costs. Reduction of costs is important for developing countries where money and personal resources are limited.

Methods

We compared the Monolisa® HCV Antigen-Antibody Ultra (Bio-Rad Laboratories Limited, Marnes La Coquette, France) with the AXSYM HCV version 3.0 (Abbot Diagnostics, Germany)-the latter assay detecting only antibodies to HCV. Seventy three HCV-PCR positive and negative samples were tested.

Results

Although the two assays showed comparable results, two samples from a bone marrow transplant (BMT) patient of viral loads 7.8 × 10₅ and 8.9 × 10₆ IU/mL could not be detected by the Monolisa® HCV Antigen-Antibody Ultra assay. Failure to detect the two samples with viral loads considered above threshold of detection for antigen proteins suggested a lack of sensitivity by this assay to discover viral capsid protein in patient samples. Genotyping of these samples revealed genotype 1b, a HCV-subtype which is widespread and should thus be easily detected.

Conclusion

We conclude that although this assay depicts high sensitivity and specificity in detecting antibodies to HCV, it seems not to add further benefit in our study population to detect HCV infections by enhanced sensitivity due the potential contingency to trace viral capsid antigens.     

Risky Sexual Behavior and Predisposing Factors among Students of Jimma University,Ethiopia

Background

Students of higher institutions are assumed to be exposed to many risky sexual behaviors. However, little has been explored about the magnitude of risky behavior and predisposing factors in the context of higher education institutions in Ethiopia. Thus, the objective of this study was to assess the pattern of risky sexual behaviors and predisposing factors among Jimma University students.

Methods

This cross-sectional study was conducted in November 2009 involving quantitative and qualitative methods. The quantitative study was conducted on 1010 students selected by multistage cluster sampling technique. The data were collected using self-administered questionnaire and analyzed using SPSS V.16.0. Multi-variate logistic regression was used to see association between variables. The qualitative part involved 10 focus group discussions and 17 key-informant interviews selected purposively. The qualitative data were analyzed by thematic areas.

Results

Among the respondents, 267(26.9%) ever had sexual intercourse. The mean age at first sexual intercourse was 17.7±2.7 years. Most, 75.6%, started sexual intercourse during secondary school. Among whoever had sex, 51.0% had sex in the last 12 months and 28.3% had multiple sexual partners. Consistent condom use with non-regular partner in the last 12 months was 69.1%. Lack of parental control, substance use, peer pressure, campus and outside environment were identified as predisposing factors.

Conclusion

Risky sexual behaviour such as having multiple sexual partner and sexual practice without condom with non-regular partner exists. The university and local health bodies should work together to address the identified risky behaviours with particular focus on Behaviour change communication.     

Human intestinal schistosomiasis in communities living near three rivers of jimma town, South Western ethiopia

Background

Schistosoma mansoni is one of the parasites with high public and medical importance in Ethiopia. However, information is scarce about S. mansoni epidemiology in people living with higher risk of infection in Jimma town. This study was designed to determine point prevalence, intensity and risk factors of S. mansoni infection among residents nearby three rivers of Jimma town and assess the rate of Biomphalaria species shading cercariae from January to April, 2007.

Methods

A cross-sectional study was conducted in communities residing nearby three rivers of Jimma town. Structured questionnaires were used to collect data on socio- demographic and behavioral risk factors. After physical examination, stool samples were collected from 517 study participants and processed with Kato-Katz technique for microscopic examination and quantification of egg load. Snails were collected for identification of Biomphalaria species and then checked for cercarial shading.

Results

The prevalence of S. mansoni was 26.3 % with intensity ranging 24 to 936 eggs per gram of stool. Participants in the age group 10–19 years, OR = 2.19 (95% CI; 1.10 – 4.34), and those living near the Awetu River, OR = 2.67 (95% CI; 1.06 – 6.75), had higher risk of S. mansoni infection. Moreover, water contact while crossing a river, OR = 3.77 (95% CI; 1.79 – 7.95), and swimming, OR = 2.59 (95% CI; 1.37 – 4.91, was significantly associated with infection. Biomphalaria snails collected from Chore and Awetu Rivers shaded higher rate of cercariae compared with Kito River.

Conclusion

A moderate prevalence of S. mansoni infection was shown in the study population. Infection rate among the residents correlated with rate of cercarial shading Biomphalaria snails. Treatment of targeted groups, appropriate health education and environmental measures (e.g. snail control) are needed to improve the situation.     

Knowledge, attitude and practice of emergency contraception among graduating female students of jimma university, southwest ethiopia

Background

Emergency contraception refers to methods that women can use to prevent pregnancy after unprotected sexual intercourse, method failure or incorrect use. Unwanted pregnancy followed by unsafe abortion can be avoided by using different contraceptive methods including emergency contraceptives. The objective of this study was to assess the knowledge, attitude and practice of emergency contraception among graduating female students of Jimma University main campus.

Methods

A cross-sectional study was conducted in Jimma University main campus in 2009. The calculated sample size was allocated to each faculty proportions to size of female students. Then within the faculty the sample unit was selected by using simple random sampling technique. Data was collected using self administered questionnaire and analyzed using SPSS for widow version 16.0.

Results

A total of 389 (96.5%) volunteered graduating female students participated in the study. One hundred sixty three (41.9%) were ever heard of Emergency Contraceptive, only 11(6.8%) used the method. The common sources of information were friends 60 (36.5%), radio 37 (22.8%) and television 20 (12.3%). One hundred sixteen (71.2%) agreed to use Emergency Contraceptive when they practice unintended sexual intercourse.

Conclusion

Awareness and use of emergency contraception among graduating female students of Jimma University was low. There is a need to educate adolescents about emergency contraceptives, with emphasis on available methods and correct timing of use.     

Risk Factors for Cardiovascular Diseases among Diabetic Patients In Southwest Ethiopia

Background

Studies on cardiovascular risk factors among diabetic persons in Ethiopia are lacking. The objective of this study was to determine the prevalence of the cardiovascular risk factors (hypertension, obesity, physical inactivity, dyslipidemia and smoking) among diabetic patients at the diabetic clinic of Jimma University Specialized Hospital.

Methods

A cross-sectional study was conducted from October to December 2007. Three hundred one individuals were randomly selected from 950 patients on follow-up. Data were collected using a structured format and appropriate equipments and reagents. Laboratory data were recorded in a separate checklist. The data were entered into SPSS for Windows version 12. Multivariate regression analysis was carried out to identify predictors of hypertension, obesity and dyslipidemia.

Results

Two hundred and fifty six (85.1%) of the sample participated in the study. The prevalence of hypertension, obesity, dyslipidemia, physical inactivity and current smoking was 46.5%, 23.4%, 63.5%, 55.1% and 5.5% respectively. Age ≥ 45 years, type 2 diabetes and obesity were predictors of hypertension. Females were less likely to be hypertensive (OR =2.26, 3.37, 3.79 and 0.48 respectively). Type 2 diabetics and females were more while rural diabetics were less likely to be obese. (OR =6.08, 4.17 and 0.37 respectively). Female gender, hypertension and fasting blood glucose ≥ 180mg/dl were predictors of dyslipidemia. Alcohol users were less likely to be dyslipidemic. (OR =4.25, 3.5, 3.56 and 0.39, respectively)

Conclusion

Hypertension, obesity, dyslipidemia and physical inactivity were common while smoking was uncommon among diabetic patients in Jimma University Specialized Hospital. Type 2 DM was a predictor of hypertension and obesity. Diabetic women were more likely to be obese and dyslipidemic. We recommend screening and management of these risk factors.     

Calcium,Magnesium, Iron,Zinc and Copper,Compositions of Human Milk from Populations with Cereal and ‘Enset’ Based Diets

Background

As breast milk is normally the only source of food in the early stages of life, the dietary levels of the essential elements in the milk of lactating mothers are significantly important. Ethiopia is a country of many nations and nationalities with distinct dietary habits. This variation in food habit may result in the variation of the nutritional quality of milk of lactating mothers who live in different part of the country, which in turn may affect the intake of nutrients by breast-fed infants. Therefore, a cross-sectional study of the levels of Ca, Mg, Fe, Zn and Cu in milk of mothers from societies with cereal and ‘enset’ based dietary habits was carried out to assess the influence of maternal diet on the levels of the elements in human milk.

Methods

Milk samples were collected from 27 voluntary mothers in Jimma and in 18 rural areas of Welkite. Breast milk samples were collected within four days postpartum and the concentrations of the elements were determined by using FAAS.

Results

Average concentrations (mg/L) of the elements determined in the milk of mothers from Jimma and rural Welkite respectively were: Ca (758 ± 107, 579 ± 168); Mg (22.6 ± 7.87, 30.5 ± 13.4); Fe (0.50 ± 0.08, 0.41 ± 0.17); Zn (2.3 ± 1.2, 2.49 ± 0.88) and Cu (0.28 ± 0.14, 0.16 ± 0.08).

Conclusions

Milk samples from Jimma were found to have significantly higher levels of Ca and Cu than those of rural Welkite (P < 0.05). Breast milk Ca and Cu levels were thus found to be influenced by dietary intake.     

The Ahmed Glaucoma Valve in Refractory Glaucoma: Experiences in Southwest Ethiopia

Background

The management of refractory glaucoma is a challenging task for any glaucoma surgeon. This study is aimed to evaluate the efficacy of Ahmed Glaucoma Valve implantation in refractory glaucomas in South-West Ethiopia.

Methods

A retrospective review was conducted on the charts of consecutive patients treated with Ahmed glaucoma valve implantation at Jimma University Specialized Hospital between August 2012 and August 2014. Success was defined as Intraocular Pressure (IOP) less than 22 mm Hg and greater than 5mm Hg at 6 months, with at least 30% reduction from baseline, without medical therapy (complete success) or either with or without medication (qualified successes).

Results

A total of 12 eyes of 11 patients were included. The mean age of patients was 40.7 (SD= 19.0) years; 63.6% of them were males. The main types of glaucoma were pseudoexfoliative (3 eyes), uveitic (2 eyes), chronic angle closure (2 eyes) and Juvenile Open Angle (JOAG) (2 eyes). The mean IOP was reduced from preoperative level (32.75±7.14 mmHg) to (15.75 ±4.35 mmHg) at six postoperative months, (P<0.001); 66.7% eyes had complete successes while 83.3% had qualified success. Intra-operative complications were encountered in 2(16.7%) eyes, while 5/12 (41.7%) eyes had post-operative complications-hypotony (one with choroidal effusion) and progression of cataract in 2 eyes each. Hypertensive phase was diagnosed in 2(16.7%) eyes.

Conclusion

The Ahmed glaucoma valve implant appears to be effective and relatively safe for treating complicated glaucomas with success rate comparable with those reported from other studies. KEYWORDS: Ahmed glaucoma valve, refractory glaucoma, complications, Ethiopia     

Clinical Characteristics of Cataract Patients with Pseudoexfoliation Syndrome at Jimma University Specialized Hospital,South West Ethiopia

Background

Pseudoexfoliation is the most common identifiable cause of secondary glaucoma and pseudoexfoliation patients have higher rates of intraoperative and postoperative complications of cataract surgery compared to those without the condition. Hence, the objective of this study was to assess the clinical characteristics of pseudoexfoliation syndrome among cataract patients examined at Jimma University Specialized Hospital, Southwest Ethiopia.

Methods

A cross-sectional clinic based study was conducted from January–March 2009. A total of 402 subjects with cataract were examined for the presence of pseudoexfoliation material, type of cataract, intraocular pressure, glaucoma and other factors. The presence of any exfoliation material on the iris, pupil and lens capsule was examined. Data were computed using SPSS version 16.0.

Results

Out of the 402 patients examined, 144(35.82%) of them had presenile and senile cataract with pseudoexfoliation and out of these 144 cases, 48(33%) were unilateral and 96(66.7%) were bilateral. Furthermore, 41(28.5%) cases had raised intraocular pressure, of which 2(4.9%) cases had chronic angle closure glaucoma and 39(95.1%) of the cases had open angle pseudoexfoliative glaucoma. There was also lens sublaxation in 10(6.9%) of the cases and dislocation in 6(4.2%) of the cases. The prevalence of PEX was higher (41%) in the age group of 70 years and above followed by 60–69 years (27.8%).

Conclusion

A significant number of patients with PEX had poor zonular integrity and high IOP and/or glaucoma. Population based studies are recommended to assess its prevalence in the general population and its association with cataract and glaucoma.     

A Meta-Analysis of Drug Resistant Tuberculosis in Sub-Saharan Africa: How Strongly Associated with Previous Treatment and HIV Co-Infection?

Background

In Sub-Saharan Africa, the fight against tuberculosis (TB) has encountered a great challenge because of the emergence of drug resistant TB strains and the high prevalence of HIV infection. The aim of this meta-analysis was to determine the association of drug-resistant TB with anti-TB drug treatment history and HIV co-infection.

Methods

After electronic based literature search in the databases of Medline, HINARI, EMBASE and the Cochrane library, article selection and data extraction were carried out. HIV co-infection and previous history of TB treatment were used as predictors for the occurrence of any anti-TB drug resistant or multiple drug resistant TB (MDR-TB). The risk ratios for each included study and for the pooled sample were computed using the random-effects model. Heterogeneity test, sensitivity analyses and funnel plots were also done.

Results

The pooled analysis showed that the risk of developing drug-resistant TB to at least one anti-TB drug was about 3 times higher in individuals who had a previous history of anti-TB treatment than new TB cases. The risk of having MDR-TB in previously anti-TB treated TB cases was more than 5-fold higher than that of new TB cases. Resistance to Ethambutol and Rifampicin was more than fivefold higher among the previously treated with anti-TB drugs. However, HIV infection was not associated with drug-resistant TB.

Conclusion

There was a strong association of previous anti-TB treatment with MDR-TB. Primary treatment warrants special emphasis, and screening for anti-TB drugs sensitivity has to be strengthened.
