Predictors of adherence to antiretroviral therapy among people living with HIV and AIDS at the regional hospital of Sokodé, Togo

BackgroundAdherence to antiretroviral therapy (ART) is beneficial in reducing the risk of emergence of HIV resistant strains. Adherence to ART among Persons Living with HIV/AIDS (PLWHA) is influenced by several factors related to the patient, the medication, and health facilities. In Togo, previous studies on adherence to ART have reported good adherence to ART during the first year of follow-up. However these may hide many disparities dues to cultural specificities which may differ across geographic areas of the country. We sought to determine the level of adherence to ART and document the associated factors among PLWHA at the regional hospital of Sokodé, Togo.MethodsThis was an analytical cross-sectional study conducted from May to July 2013 at the regional hospital of Sokodé among 291 PLWHA who had been on ART for at least three months before the study.ResultsA total of 291 PLWHA on ART were enrolled in the study. The mean age (±SD) was 37.3 ± 9.3 years and the sex ratio (Male/Female) was 0.4. Among them, 195 (67.0%) were living with their partners and 210 (72.2%) had formal education. Two-thirds (194/291; 66.7%) of the PLWHA interviewed lived in urban areas. The global adherence to ART was 78.4%; the factors associated with ART adherence were: level of education (aOR = 3.54; p = 0.027), alcohol consumption (aOR = 0.43; p = 0.033), ART perception (aOR = 2.90; p = 0.026) and HIV status disclosure to sexual partner (aOR = 7.19; p ≤ 0.001).ConclusionAlthough the level of adherence to ART in this study was higher than those reported in some studies in Sub-Saharan Africa, it remains sub-optimal and needs improvement. This may therefore hinder the implementation of efficient interventions related to access to ART services.

Morbidity and mortality due to malaria in Est Mono district, Togo, from 2005 to 2010: a times series analysis

BackgroundIn 2004, Togo adopted a regional strategy for malaria control that made use of insecticide-treated nets (ITNs), followed by the use of rapid diagnostic tests (RDTs), artemisinin-based combination therapy (ACT). Community health workers (CHWs) became involved in 2007. In 2010, the impact of the implementation of these new malaria control strategies had not yet been evaluated. This study sought to assess the trends of malaria incidence and mortality due to malaria in Est Mono district from 2005 to 2010.MethodsSecondary data on confirmed and suspected malaria cases reported by health facilities from 2005 to 2010 were obtained from the district health information system. Rainfall and temperature data were provided by the national Department of Meteorology. Chi square test or independent student’s t-test were used to compare trends of variables at a 95% confidence interval. An interrupted time series analysis was performed to assess the effect of meteorological factors and the use of ACT and CHWs on morbidity and mortality due to malaria.ResultsFrom January 2005 to December 2010, 114,654 malaria cases (annual mean 19,109 ± 6,622) were reported with an increase of all malaria cases from 10,299 in 2005 to 26,678 cases in 2010 (p<0.001). Of the 114,654 malaria cases 52,539 (45.8%) were confirmed cases. The prevalence of confirmed malaria cases increased from 23.1 per 1,000 in 2005 to 257.5 per 1,000 population in 2010 (p <0.001). The mortality rate decreased from 7.2 per 10,000 in 2005 to 3.6 per 10,000 in 2010 (p <0.001), with a significant reduction of 43.9% of annual number of death due to malaria. Rainfall (β-coefficient = 1.6; p = 0.05) and number of CHWs trained (β-coefficient = 6.8; p = 0.002) were found to be positively correlated with malaria prevalence.ConclusionThis study showed an increase of malaria prevalence despite the implementation of the use of ACT and CHW strategies. Multicentre data analysis over longer periods should be carried out in similar settings to assess the impact of malaria control strategies on the burden of the disease. Integrated malaria vector control management should be implemented in Togo to reduce malaria transmission.

HIV prevalence and behavioral studies in female sex workers in Togo: a decline in the prevalence between 2005 and 2011.

Introduction We determined the sero-prevalence of HIV among female sex workers (FSWs) in Togo identified their sexual risk behaviors. Methods We conducted a cross-sectional study from 17 to 27 December, 2011 on 1106 FSWs in Togo. Venous sample were collected to estimate HIV prevalence as per national algorithms. Behavior data were collected by interviewer-administered questionnaires. Results Of the 1106 FSWs (mean age = 27.6 years) surveyed, 17% and 63% had their first sexual intercourse before the age of 15 and 18 years respectively. Overall, 43.4% of the FSWs had more than seven clients per week. Most FSWs (95%) said they had sex using a condom in their lifetime while 8.8% had used a condom during their last sexual intercourse. About 79% of FSWs used a condom during their sexual encounters the previous week and 11.6% had used a condom during each of their sexual encounters the previous day. Most FSWs (62.2%) reported to have been tested for HIV. Of these, 145 (13.1%) were HIV positive. HIV sero-prevalence decreased from 19.4% in the south to 7.5% in the north of the country. Behaviors associated with FSW being HIV positive included: FSW having more than 7 clients per week (p < 0.001), not using condoms at every intercourse act (p = 0.003) or during the last sexual encounter (p = 0.006) and trading sex in brothels (p < 0.001). Conclusion We estimate HIV sero-prevalence among FSWs in 2011 to be 13.1% in Togo, significantly lower than a prevalence of 29.5% estimated previously in 2005. Inconsistent use of condoms was identified as associated with high risk factor for acquiring HIV.

HIV Status Disclosure to Sexual Partners, among People Living with HIV and AIDS on Antiretroviral Therapy at Sokodé Regional Hospital, Togo

Background Many studies have reported factors associated with HIV status disclosure among People Living With HIV and AIDS (PLWHA) but very few were conducted among PLWHA receiving ART. In Togo, no study on HIV status disclosure to sexual partners has been conducted among PLWHA on ART yet. We sought to document factors associated with HIV status disclosure among PLWHA receiving ART at Sokodé regional hospital in Togo. Method This was a cross-sectional study conducted from May to July 2013 at the regional hospital of Sokodé among 291 PLWHA who had been on ART for at least three months. Results A total of 291 PLWHA on ART were enrolled in this study. Their mean age (±SD) was 37.3±9.3 years and the sex ratio (Male/Female) was 0.4. Among them, 215 (74.6%) completed the questionnaire on HIV sero-status disclosure. We found that 131 PLWHA (60.9%) had disclosed their HIV sero-status to their sexual partners; 130 (60.5%) were aware of the HIV status of their sexual partners. In the multivariate analysis, the factors associated with HIV status disclosure to sexual partners were: adherence to ART (aOR = 4.89; 95%CI = [1.52; 15.78]), sexual partner awareness of HIV sero-status (aOR = 52.73; 95%CI = [14.76; 188.36]) and marital status of PLWHA (aOR = 6.10; 95%CI = [1.74; 21.37]). Conclusion This study allowed us to note that the disclosure of HIV status to sexual partners is relatively low and to document the associated factors such as adherence to ART, sexual partner awareness of HIV sero-status and marital status.

Loss of HIV-infected patients on potent antiretroviral therapy programs in Togo: risk factors and the fate of these patients

Introduction National programs are facing challenges of loss to follow-up of people living with HIV/AIDS (PLWHA) on antiretroviral therapy (ART). We sought to identify risk factors associated with early loss to follow-up among HIV-infected patients on ART in Togo and the outcome of such patients. Methods This was a retrospective cross-sectional study using medical records of all patients older than age 15 years enrolled at 28 treatment centers who were on ART programs and who were lost to follow-up from 2008 to 2011. Results Of the 16,617 patients on ART, 1,216 (7.3%) were lost to follow-up. Most (94.1%) were infected with HIV-1 and 32.6% were in WHO stage III or IV. The median CD4 count was 118/mm3 (IQR: 58-178 cells/mm3). No telephone number was mentioned in the medical records of 212 patients. Of the 1004 patients whose phone number was listed, 802 patients (79.9%) were not reachable on the recorded number, 114 patients (11.4%) were alive and 88 patients (8.8%) had died. In multivariate analysis, factors associated with loss to follow-up during the first 6 months of ART were: age below 35 years (OR = 1.6; 95%CI: 1.2-2.2), female sex (OR = 1.8; 95%CI: 1.3-2.5), WHO stage III or IV (OR = 1.7; 95%CI: 1.3-2.2), existence of an opportunistic infection (OR = 2.3; 95%CI: 1.5-3.1), and follow-up in a public centre (OR = 1.9; 95%CI: 1.2-3.3). Conclusion This study identified several factors associated with lost to follow-up during the first 6 months of ART, and confirmed high mortality among these patients. The National AIDS Program should strengthen medical support of PLWHA in Togo including active case follow-up.

Is There an Association between Keloids and Blood Groups

Objective. The aim of the study is to investigate the possible associations between the blood groups ABO and Rhesus systems and the presence of keloids in patients with black skin. Method. This case-control study was conducted between September 2007 and August 2011 comparing dermatologic outpatients with keloids to matched controls recruited in preanesthetic consultation at Tokoin Teaching Hospital of Lomé (Togo). Results. The distribution of different ABO blood groups and Rhesus blood groups in both groups (cases versus controls) was not significantly different. This distribution of different blood groups was superimposed on the general population of blood donors at the National Blood Transfusion Center of Lomé. Univariate analysis between each blood group and the presence of keloid does not yield any statistically significant association between blood groups and presence of keloids in the subjects. Conclusion. The study shows no significant association between blood groups and the presence of keloids in our patients. Further investigation needs to be conducted to elucidate this hypothesis further by conducting multicenter studies of several ethnic groups.

Consistent Condom Use during Casual Sex among Long-Truck Drivers in Togo

Background In 2008, the proportion of truck drivers who were not systematically protected during sex was 63% with casual partners and 60% with sex workers. Despite the high level of knowledge on HIV/AIDS and the growing awareness of the existence of the risk of HIV infection, condom use always encounters resistance among truck drivers in Togo. We sought to document the factors associated with condom use during casual sex among trucks’ drivers in Togo. Methods This was an analytical cross-sectional study conducted in 2010 and targeted truckers at truck station on the two main roads of Togo, Lomé-Cinkassé and Kodjoviakopé-Sanvee Condji. Results In this study, 1,782 trucks’ drivers and their helpers were interviewed. All were men, and their mean age was 28.8 ± 8.8 years. Trucks’ drivers were doing an average of 3 stops on their journeys and 1,229 (69%) of them had at least two years of experience in the work. Of the 1,782 trucks’ drivers, only 620 (34.8%) had consistently used condoms during casual sex in the last three months. In multivariate analysis, predictors were: education level (primary schooling: OR = 1.54; p = 0.002; Secondary schooling and higher OR = 1.38; p = 0.036), good knowledge of ways of HIV transmission (OR = 1.53; p = 0.000), tested for HIV (OR = 1.67, p = 0.000), duration in the profession (2–5 years: OR = 1.43, p = 0.008; more than 5 years: OR = 1.38, p = 0.027), and HIV risk’s perception (OR = 1.44, p = 0.000). Conclusion These results highlight factors associated with consistent condom use during casual sex by truck drivers in Togo. This is a key population group at high risk of HIV transmission toward which the national HIV/AIDS control program should strengthen the HIV prevention strategies.
