Mortality impact of AIDS in Addis Ababa,Ethiopia

OBJECTIVE: To measure the impact of HIV on mortality in Addis Ababa, Ethiopia. DESIGN: A retrospective review of burials at three cemeteries, 1987-2001 and a prospective surveillance of burials at all (n = 70) cemeteries, February-May, 2001. METHODS: The age, sex, and date of burial were recorded; in the absence of denominators, we compared the ratio of deaths of persons 25-49 versus 5-14 years of age per calendar year, using logistic regression, adjusting for sex and site. The age- and sex- specific mortality were calculated and compared with pre-HIV mortality in 1984. RESULTS: Of 17,519 deaths, retrospectively reviewed, complete data were available for 6342 (47%) females and 7269 (53%) males. During 1987-2001, the '25-49' versus '5-14' group all-cause mortality ratio increased by 8.5% per calendar year (P < 0.05). A total of 5101 deaths were recorded in the prospective surveillance. Crude mortality rates were 9.5/1000 per year (men) and 7.1/1000 per year (women). In comparison with 1984, 5.0-times as many men and 5.3-times as many women died in the age group 35-39 years. Attributing the increase in mortality in ages 15-60 to HIV in the period 1984-2001, Ethiopian men and women have a probability of 18.8 and 17.8%, respectively, of dying of HIV before age 60. CONCLUSION: Burials increased significantly among the '25-49', versus the '5-14' group, during the period 1987-2001. This trend, and a five-times higher mortality in 2001 than in 1984 in those aged 35-39 years demonstrate a severe impact of HIV on mortality. Continuing surveillance of burials is recommended.     

Intestinal microsporidiosis in diarrheal patients infected with human immunodeficiency virus-1 in Addis Ababa, Ethiopia

Intestinal microsporidiosis is most commonly associated with persistent diarrhea in advanced AIDS cases. To determine the prevalence and clinical manifestations of this infection in HIV/AIDS patients, a single fresh stool sample and blood were collected from 243 (214 HIV-positive and 29 HIV-negative) diarrheal patients. The presence of intestinal microsporidiosis in the stool was determined by Uvitex-2B staining and a PCR-based detection method. HIV screening was done by using ELISA, and reactive samples were confirmed by Western blotting. The CD4+ cell count was analyzed using FACScan. Out of 243 diarrheal patients, 39 (16.0%) cases were positive for intestinal microsporidial infection by either of the methods used. Of the 39, only 18 cases positive by microscopy were also positive by PCR. Based on PCR and microscopic analyses the microsporidial parasites were identified as Enterocytozoon bieneusi (30), Ecephalitozoon intestinalis (6), and double infections (3). All microsporidia-positive cases were HIV-positive, and 92.3% had diarrhea for over 4 weeks. The diarrhea was watery in 79.5% of the patients. Weight loss >10% was recorded in 37 (94.9%) cases. The CD4+ cell count was <100 cells/mm(3) in 84.4% of subjects, and 59.4% of the patients had a CD4+ cell count of < or =50 cells/mm(3), with a mean of 22.8 cells/mm(3). This study revealed that intestinal microsporidiosis is a common cause of chronic diarrhea and severe weight loss in advanced AIDS patients in Ethiopia. This condition is attributable mainly to E. bieneusi. Thus, early diagnosis of intestinal microsporidiosis in HIV/AIDS patients would certainly be helpful in the understanding and management of diarrheal illness.     

Factors associated with HIV-1 infection among sex workers of Addis Ababa, Ethiopia

OBJECTIVE: To study the prevalence and risk factors for HIV infection among sex workers of Addis Ababa, Ethiopia. Design and methods: Cross-sectional survey on socio-demographic characteristics, behaviours, and HIV serological status of sex workers attending two health centres of Addis Ababa. RESULTS: HIV prevalence among sex workers was 274 of 372 (73.7%). Several factors were significantly associated with an increased risk of being HIV-infected [among others, working in 'shared rooms', high number of clients, use of injectable hormones, and positive Treponema pallidum particle agglutination (TPPA) serology], and others with a decreased risk (being born in Addis Ababa, high level of education, peer education on sex work, condom use, use of oral pill, and use of condoms for contraception). Of interest, sex workers who were using condoms for contraception were, compared with others, more likely to use condoms consistently (65 versus 24%, respectively; P < 0.001), and less likely to be HIV-infected (55 versus 86%, respectively; P < 0.001). In multivariate analysis [log-binomial model, giving estimates of the prevalence ratio (PR)], being born in Addis Ababa (PR = 0.74; 95% confidence interval (CI), 0.61-0.91), using condoms for contraception (PR = 0.73; 95% CI, 0.64-0.85), and a positive TPPA serology (PR = 1.21; 95% CI, 1.09-1.36), remained significantly associated with HIV infection. CONCLUSIONS: HIV prevalence was remarkably high among sex workers of Addis Ababa. Condom use was higher, and HIV prevalence lower, in sex workers using condoms not only for prevention of HIV and sexually transmitted diseases, but also for contraceptive purpose. This finding is of particular interest for its implications for prevention strategies among sex workers in the developing world.     

The occurrence and driver characteristics associated with motor vehicle injuries in Addis Ababa, Ethiopia.

Ethiopian documentation of the occurrence and determinants of motor vehicle related morbidity and mortality is sparse. The purpose of this investigation was to determine the incidence of hospital treated motor vehicle injuries (MVI) in Addis Ababa and driver characteristics associated with involvement in a MVI. The study was conducted over a 12-week period in the autumn of 1988. Over 91% of MVI involved pedestrians. The overall MVI incidence density rate was 279.4 per 100,000 person years and the mortality rate was 17.6 per 100,000 population per year. Road accident injury and fatality rates were 946 and 59.5 respectively per 10,000 registered vehicles. Overall years of person life lost was 595 per 100,000 person-years exposure. Significantly increased odds of exposure among drivers inflicting a MVI were found for younger age, fewer years driving experience, male gender, and those driving newer, government owned, and mass transit vehicles.     

Predictors of voluntary HIV counselling and testing services utilization among people with disabilities in Addis Ababa,Ethiopia

The study investigated HIV testing prevalence and factors associated with the utilization of voluntary HIV counselling and testing (VCT) services among individuals with disabilities in Addis Ababa. The analysis was based on a survey of 209 men and 203 women with disabilities, aged 15–49, who had ever heard about HIV and AIDS in four sub-cities in Addis Ababa. HIV testing prevalence was 53.2%, with no significant difference between males and females. Comprehensive HIV knowledge, living with spouse, and religious affiliations positively predicted utilization of VCT services among participants. Living with both parents and having physical or mental/intellectual disabilities were negative predictors of VCT services utilization. More research on the predictors of utilization of VCT services by gender and urban/rural divides are needed among people with disabilities.     

Lay diagnosis of causes of death for monitoring AIDS mortality in Addis Ababa, Ethiopia

Lay diagnoses of death collected at burial sites were validated against two 'gold standards': the hospital discharge diagnosis of causes of death obtained by a surveillance of hospital deaths (including autopsy results) and the physician review of verbal autopsies (VAs) that were carried out for a sample of cemetery records. The diagnostic indicators of the lay diagnoses were then used to provide estimates of the share of AIDS-attribuTable mortality. The verbal autopsy results provide an independent estimate of the percentage of AIDS deaths. From a total of 21,274 burial records, 2546 hospital discharge diagnoses, 1480 outcomes of autopsies and 200 adult verbal autopsies were gathered over a period of 1 year starting from February 2001. Independent of the gold standard, lay diagnoses such as lung disease and cold have a specificity of about 90% and a combined sensitivity of about 55% in determining AIDS mortality. Without a significant loss in specificity, the sensitivity increases to 60-65% when diarrhoea, TB, herpes zoster and mental or nerve problem are included. We thus conclude that even in the presence of a reluctance to talk of HIV/AIDS, lay diagnosis of causes of death can be used for monitoring AIDS mortality. Lung disease and cold, in particular, have become well-known euphemisms for AIDS in the community. The share of AIDS deaths in the adult population (20-54) is estimated at 68%, without noticeable differences between men and women. Our results confirm the high impact of HIV/AIDS on mortality as was estimated by epidemiological projections for Addis Ababa.     

The economic impact of HIV/AIDS morbidity and mortality on households in Addis Ababa, Ethiopia

The present study investigates whether the household-level economic impact of an adult AIDS death is different from that of death from another cause. The data come from cross-sectional post-mortem interviews (verbal autopsies) with relatives or primary caregivers of deceased adults randomly selected from deaths recorded in an ongoing burial surveillance in Addis Ababa. Our analyses consist of three parts. First, we assess the sociodemographic risk factors for AIDS mortality. Subsequently, we reverse the causal order of this relationship and carry out an analysis of the effect of AIDS mortality on the subjective experience of change in the household's financial situation following the death of a household member. Finally, we quantify the direct and indirect costs of illness and death on the household. Results indicate that households experiencing an HIV/AIDS death are poorer than those experiencing a non-HIV/AIDS death. In addition, poorer households experience a greater decline in socioeconomic status following death of a household member. AIDS mortality has more detrimental effects on the household economic status than deaths due to other causes. While the difference between AIDS and non-AIDS mortality in terms of direct costs is minimal, the indirect cost of an AIDS death per household exceeds that of non-AIDS death by 58%. In conclusion, poor households are more likely to experience an AIDS death and in turn are more vulnerable to the socioeconomic impact of death. Therefore, it is justifiable to target HIV-impact mitigation programs on poorer households.     

Attracting female sex workers to HIV testing and counselling in Ethiopia: a qualitative study with sex workers in Addis Ababa

Despite growing efforts to increase HIV testing and counselling (HTC) services for most at risk populations in Ethiopia, the use of these services by female sex workers (FSWs) remains low. With rising numbers of FSWs in Addis Ketema and concerns about their high risk behaviours, exploring and addressing the barriers to uptake is crucial. This qualitative study explores the barriers to utilising HTC facilities and identifies the motives and motivations of FSWs who seek HTC through in-depth and semi-structured interviews with female sex workers, healthcare workers and key informants. Results indicate that FSWs face numerous barriers including inability to seek treatment if found to be positive due to the requirement of an identity (ID) card many do not own. Many FSWs reported discriminatory behaviour from healthcare workers and a lack of dedicated services. What is clear from the findings is that distinct strategies, which differ from those of the broader population, are required to attract FSWs — strategies which take into account the barriers and maximise the reported motives and motivations for testing.     

Assessment of Diabetes Education in the Teaching Hospital,Addis Ababa,Ethiopia

With the aim of assessing continuing diabetes education and obtaining baseline information, we have evaluated the knowledge of 139 randomly selected diabetic patients from the Diabetes Clinic of Tikur Anbessa Teaching Hospital, Addis Ababa, Ethiopia. Seventy-five Type 1 (insulin-dependent) and 64 Type 2 (non-insulin-dependent) diabetic patients, with a mean age of 36 ± 14 (± SD) (range 15–78, median 36) years, and mean duration of known diabetes 6.3 ± 5.5 (range 1–30, median 5) years participated in the study. Knowledge was assessed by a questionnaire which examined three principal areas: general knowledge on diabetes mellitus, diet plus self care, and chronic complications. Twenty-eight (20.1 %), did not attend any and 59 (42.5 %) attended the diabetes education programme more than once. The Adjusted Percentage Score (APSCORE) was 69 ± 1.4 (SEM). Type 1 diabetic patients had a significantly higher score (p < 0.001) for overall knowledge when compared to Type 2 patients. In both groups the knowledge on chronic complications was very poor when compared to the other areas (p < 0.001). No sex difference in knowledge was seen. Higher school and diabetes education attendance had a significant influence on the knowledge of diabetes. However, better knowledge about diabetes was not associated with better glycaemic control as measured by the fasting blood glucose concentration. The wide difference in knowledge, the low rate of attendance at diabetes education sessions, and the very low awareness about chronic complications is very worrying. To achieve the intended aim the diabetes education programme needs to be revised.     

Prevalence of HIV and other infections and injection behaviours among people who inject drugs in Addis Ababa,Ethiopia

Background: Ethiopia is one of the sub-Saharan African countries most affected by HIV/AIDS. However, the country lacks data describing the extent of the epidemic among people who inject drugs (PWID). Thus, a bio-behavioural study was conducted in 2015 to generate strategic information on the magnitude of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis and related risk behaviours among PWID in Addis Ababa.

Methods: A cross-sectional study using respondent-driven sampling was conducted among people reported to have injected illicit drugs within 6 months before the study. Males and females aged 15 years or above and who were resident in Addis Ababa were included in the study between 26 March and 22 May 2015. Data was analysed using respondent-driven (RDS) Analyst software.

Results: A total of 237 participants, including 6 seeds, enrolled in the study; most of the PWID were males (96%) with a mean age of 26 years. Most (79%) of the PWID reported injecting heroin but also reported using non-injecting drugs, including marijuana or ganja (47%) and/or khat (31%). Forty per cent of PWID reported ever sharing needles and 56% reported sharing other injecting equipment. However, only 14% reported injecting daily, and 49% reported injecting only 1 to 3 times a month. HIV prevalence was 6%, HBV was 5.1%, HCV was 2.9% and syphilis 5.1% among PWID. Among HIV-positive PWID, 60% reported sharing a needle the last time they injected.

Conclusion: Even though the prevalence of HIV among drug users is not much higher than in the general population in Addis Ababa, the needle sharing prevalence was high. Thus, this baseline study shows the need to establish harm reduction programmes and prevention strategies for the PWID in Addis Ababa.     

Temporal trends in the incidence of HIV infection in antenatal clinic attendees in Addis Ababa, Ethiopia, 1995-2003

BACKGROUND: The HIV incidence data are relevant in depicting the current dynamics and trend of the epidemic. Using a new laboratory method for HIV-1 incidence, we aimed at estimating a 10-year trend in HIV-1 incidence in Addis Ababa, Ethiopia. METHODS: We determined the temporal trends in HIV incidence based on a total of 7744 serum specimens from pregnant women who attended antenatal clinics in Addis Ababa between 1995 and 2003. HIV incidence was determined by IgG-capture HIV-1 BED incidence enzyme immunoassay following a validation using a well-characterized panel of serial serum specimens from subtype C-infected seroconverters. FINDINGS: Of the 1350 HIV+ specimens tested as part of the annual sentinel survey between 1995 and 2003, a total of 1332 (98.7%) were tested by BED HIV-1 incidence assay. The incidence rate of HIV-1 infection declined significantly from 7.7% (95% CI, 3.9-11.5%) in 1995 to 2.0% (95% CI, 0.7-3.3%) in 2003. Although there was a trend, amongst the age group of 15-29 years, in age-specific decline in incidence, it was not statistically significant. No change in HIV incidence rate was observed for the group aged above 30 years. INTERPRETATION: A corresponding decline in the incidence of HIV infection was observed with the decline in the prevalence of HIV infection between 1995 and 2003 in Addis Ababa City. Whether the declines were because of changes in sexual behaviours or other reasons needs to be explored. The BED HIV-1 incidence assay provides a valuable tool in obtaining information on recent HIV-1 infection.     

Immune reconstitution inflammatory syndrome among HIV/AIDS patients during highly active antiretroviral therapy in Addis Ababa, Ethiopia

Suppression of viral replication is followed by increases in CD4+ lymphocytes, and this has been shown to result in decreased susceptibility to opportunists after initiation of highly active antiretroviral therapy (HAART). However, clinical aggravations after the initiation of HAART have been thought to be due to the restored ability to mount an inflammatory response, or the immune reconstitution inflammatory syndrome (IRIS). The degree of IRIS observed in human immunodeficiency virus (HIV)-infected patients following initiation of HAART is variable. This prospective study was aimed at determining the proportion of IRIS and the pattern of opportunistic infections among 186 HIV/AIDS patients receiving HAART between December 2006 and July 2007 at Zewditu Memorial Hospital, Addis Ababa, Ethiopia. The proportion of IRIS was 17.2% (32/186). The mean number of days of IRIS occurrence for each disease ranged from 26 to 122 days with a mean of 80. Opportunistic diseases associated with IRIS were tuberculosis (68.8%, 22/32), herpes zoster rash (12.5%, 4/32), cryptococcosis (9.4%, 3/32), toxoplasmosis (6.3%, 2/32) and bacterial pneumonia (3.1%, 1/32). Compared to baseline readings there were significant increases in CD4 count, aspartate aminotransferase and alanine aminotransferase levels while hemoglobin values decreased during the development of IRIS. In summary, the proportion of IRIS and the pattern of opportunistic infections in HAART-treated patients in Ethiopia mirrored those reported in other countries. Further prospective surveys on epidemiological, immunological, microbial and clinical studies are imperative to assess the proportion and pattern of IRIS and effect of HAART in Ethiopia.     

Treatment outcome of tuberculosis patients under directly observed treatment in Addis Ababa,Ethiopia

BackgroundTuberculosis is one of the leading causes of mortality among infectious diseases worldwide. For effective tuberculosis control, it is a pre-requisite to detect the cases as early as possible, and to ensure that the tuberculosis patients complete their treatment and get cured. However, in many resource-constrained settings treatment outcome for tuberculosis has not been satisfactory.ObjectiveThe aim of the study was to assess the treatment outcome of tuberculosis patients and investigate the association of demographic and clinical factors with treatment success of patients enrolled in Directly Observed Treatment Short Course program in government owned health centers over the course of five consecutive years in Addis Ababa, Ethiopia.MethodsA register based historical cohort study covering the period of July 2004 to June 2009 was conducted to determine the treatment outcome of Directly Observed Treatment Short Course in government owned health centers in Addis Ababa. Sex and age of tuberculosis patients, health center at which the patient was treated, year of treatment, type of tuberculosis for which the patient was treated, type of treatment offered to the patient, follow-up status and documented treatment outcome were extracted from the Directly Observed Treatment Short Course clinics of three randomly selected health centers.ResultRecords of 6450 registered tuberculosis patients (n = 3147 males and 3433 females) were included in this document review. Of these patients 18.1% were reported as being cured, 64.6% were documented as treatment completed, 3.7% died during follow-up, 5.1% were reported as defaulters, 0.4% were documented as treatment failure and 8.2% were transferred out to another health institution. Treatment center and year of enrollment were significantly associated with treatment success.ConclusionYear of enrollment and treatment center were significantly associated with treatment success. Although the overall treatment success obtained in this study is in line with the World Health Organization (WHO) target, continuous follow-up of patients with frequent supportive supervision during the course of treatment, and further investigate the cause for the observed difference in treatment success across treatment centers are recommended.     

Disclosure of HIV status to infected children in a Nigerian HIV Care Programme

With increasing survival of HIV-infected children, parents face the challenges of disclosure to the children. The aim of this study was to assess the rate of HIV disclosure to children in Ibadan and the factors influencing it in order to guide design of strategies for successful disclosure. A semi-structured questionnaire was administered to consecutive consenting caregivers of HIV-infected children aged ≥6 years attending the Paediatric Infectious Disease Clinic of the University College Hospital, Ibadan, between November 2008 and October 2009. Caregivers of 96 children (46 boys, 50 girls) infected with HIV were interviewed. The ages of the children ranged from 6 to 14 years with a mean (SD) of 8.8 (2.2) years. Disclosure had been done in only 13 (13.5%) of the children; ages at disclosure ranged from 4.5 to 13 years with a mean of 8.7 (SD = 2.2). Disclosure was associated with age above 10 years. Reasons given by carers for non-disclosure in 83 caregivers included inability of the children to understand in 53 (63.9%), fear of disclosure to other children 34 (41.0%), fear of disclosure to family/friends in 28 (33.7%), fear of psychological disturbance of the children in 26 (31.3%) and fear of blaming the parents in 22 (26.5%). Twenty (20.8%) of the children have asked questions relating to their diagnosis and the responses are often evasive. Caregivers felt disclosure had helped adherence to antiretroviral therapy in 7 (63.6%) of the 11 children on antiretroviral drugs in whom there was disclosure but no effect on the remaining. There is a need to assist parents and health care providers in successfully disclosing HIV status to infected children without adverse consequences.     

Living with HIV in West Bengal,India: perceptions of infected children and their caregivers

Children living with HIV (CLH) face several physical and psychological challenges. The impact of the disease is not limited to the affected CLH, but also affects their caregivers and family members. We qualitatively explored the experiences, knowledge, concerns, and perceptions of primary caregivers and triangulated those aspects with those expressed by their CLH. We conducted 34 in-depth interviews (IDI) with primary caregivers of 8- to 15-year-old CLH residing in West Bengal, India. Four focus group discussions (FGD) with CLH were held, two each with children aged 8–12 and 13–15 years. Participants were recruited with the help of a community-based organization providing need-based services to adults and CLH. Five major themes shared by caregivers and children were identified, including concerns about HIV, medications, discriminatory behaviors, having a “healthy mind”, and the advantages and limitations of available HIV-related health services. Two primary themes exclusively from IDI with caregivers were caregiving challenges and concerns about the future of their CLH. Indian CLH and their caregivers face many daily challenges, and there are many unmet but relevant expectations. Caregiving goes beyond the child-caregiver dynamic, and is intertwined with the local community and the healthcare and support system structures. The current study underscores the need for comprehensive care programs focusing on improving support to both CLH and caregivers.     

Temporal trend and factors associated with late HIV diagnosis in Hong Kong, a low HIV prevalence locality

We studied the temporal trend of late HIV diagnosis and its determinants in Hong Kong. Three surrogate markers were used to proxy late diagnosis: AIDS within 3 months of HIV diagnosis, CD4 < 200/microL at HIV, and diagnosis at hospital. From 1984 to 2000, 1530 nonperinatal HIV infections and 495 patients with AIDS were reported. Overall, 23.9% to 52.1% of the patients were late presenters according to the three surrogates. There was no improvement in late diagnosis in the highly active antiretroviral therapy (HAART) era (1997-2000) compared to the pre-HAART era (1984-1996). Gender, ethnicity, age, and HIV exposure category were significant factors of late diagnosis on univariate analysis. On multivariate analysis, a lower risk of late diagnosis per all 3 surrogates was observed in men having sex with men (ranges of adjusted odds ratio [OR] [95% confidence interval [CI], 0.32-0.67 [0.21-0.91]) whereas the reverse was found for patients 35 years of age or older (ranges of adjusted ORs [95% CI], 1.62-2.80 [1.30-3.60]). In addition, male gender and Chinese ethnicity were associated with higher chance of having CD4 < 200/microL at HIV. The persistent trend of late HIV diagnosis in Hong Kong deserves attention. Strategies targeting infected people to enhance early HIV testing are needed, especially for those with risk factors of late diagnosis.     

Identifying barriers to HIV testing: personal and contextual factors associated with late HIV testing

Late diagnosis of HIV is associated with increased morbidity, mortality, and health care costs. Despite the availability of HIV testing, persons continue to test late in the course of HIV infection. We used the HIV/AIDS case registry of San Francisco Department of Public Health to identify and recruit 41 persons who developed AIDS within 12 months of their HIV diagnosis to participate in a qualitative and quantitative interview regarding late diagnosis of HIV. Thirty-one of the participants were diagnosed with HIV because of symptomatic disease and 50% of the participants were diagnosed with HIV and AIDS concurrently. Half of the subjects had not been tested for HIV prior to diagnosis. Fear was the most frequently cited barrier to testing. Other barriers included being unaware of improved HIV treatment, free/low cost care, and risk for HIV. Recommendations for health care providers to increase early diagnosis of HIV include routine ascertainment of HIV risk behaviors and testing histories, stronger recommendations for patients to be tested, and incorporating testing into routine medical care. Public health messages to increase testing include publicizing that (1) effective, tolerable, and low cost/free care for HIV is readily available, (2) early diagnosis of HIV improves health outcomes, (3) HIV can be transmitted to persons who engage in unprotected oral and insertive anal sex and unprotected receptive anal intercourse without ejaculation and from HIV-infected persons whose infection is well-controlled with antiretroviral therapy, (4) persons who may be infected based upon these behaviors should be tested following exposure, (5) HIV testing information will be kept private, and (6) encouraging friends and family to get HIV tested is beneficial.     

Myocardial dysfunction in patients infected with HIV: prevalence and risk factors

Objectives—To determine the prevalence of and risk factors for myocardial dysfunction in HIV infection.Subjects—173 patients infected with HIV underwent echocardiography. 119 were current or previous injection drug users, 38 were homosexuals, 10 were haemophiliac patients, and six were heterosexual.Main outcome measure—Detection of impaired ventricular function.Results—26 patients with abnormalities of ventricular size or function or both were identified. The abnormality was (a) dilated cardiomyopathy in 13 patients (eight homosexuals, three drug users, and two haemophiliacs) with a mean CD4 count of 38 cells/mm³, which accords with end-stage disease (in addition, three patients were identified as having borderline impairment of left ventricular function); (b) left ventricular dilatation without loss of function in a further six patients; and (c) isolated right ventricular dilation in seven patients. Follow up echocardiograms were obtained in 71 patients, 18 of whom had myocardial dysfunction (103 echocardiograms, mean (SD) 2·5 (0·6) scans per patient, mean interval 200 (116) days, range 14–538 days). These showed that in four cases of isolated right ventricular dilatation, one of isolated left ventricular dilatation, and two with borderline left ventricular dysfunction myocardial function subsequently reverted to normal. There was no excess of exposure to zidovudine in the patients with myocardial dysfunction. Similarly, patients with myocardial dysfunction had no serological evidence of excess secondary infection with Toxoplasma gondii and cytomegalovirus.Conclusions—There was a high prevalence and wide range of myocardial dysfunction in HIV positive patients. Dilated cardiomyopathy was a feature of advanced HIV disease and affected all major risk groups for HIV infection. In contrast, isolated dilatation of either ventricle occurred at an earlier stage of HIV infection and, particularly in the case of the right ventricle, often was transient. Neither treatment with zidovudine nor infection with Toxoplasma gondii or cytomegalovirus seemed to be responsible for these findings.

Psychosocial determinants of sexual activity and condom use intention among youth in Addis Ababa,Ethiopia

Determinants of sexual activity and intentions for condom use were examined guided by the Attitude, Social influences, and Self-efficacy (ASE) model as a theoretical framework. A total of 561 in and out-of-school youth (15-24 years) in Addis Ababa completed a self-administered questionnaire. A third of them reported sexual intercourse in the past and half of the sexually active used condoms during recent intercourse. Being out-of-school, male, aged 20-24 years, alcohol use and khat (amphetamine-like substance) consumption predicted the likelihood of engagement in sexual activity. Of these variables, however, male sex was more associated with reported condom use during recent sexual intercourse. Self-efficacy, skills, and barriers predicted 23% of the variance in intentions to use condoms. Self-efficacy was also associated with past condom use. Psychosocial constructs predicted more variations in condom use intention for males than for females. In general, self-efficacy was found to be the strongest predictor of the constructs, whereas attitude and social influences were the weakest. The study implies that HIV/AIDS prevention programmes for young people in Ethiopia need to emphasize building assertive communication skills in sexual negotiations and condom use. Minimizing the gender gap in sexual relationships forms the cornerstone for such educational strategies.
