Opportunistic Infections and associated factors among HIV infected patients on anti-retroviral treatment at Bombo Hospital in Tanga Region, Tanzania

Background: A substantive number of People Living with HIV (PLHIV) develop Opportunistic Infections (OIs). The introduction of Anti-Retroviral Therapy (ART) in Tanzania led to a significant decline in opportunistic infections and a slower progression to AIDS, but OIs are still prevalent. This study was set to determine the magnitude of OIs and associated factors among HIV/AIDS patients on Anti-Retroviral Therapy (ART) attending care and treatment clinic at Bombo Regional Referral hospital, Tanga region. Materials And Methods: A cross­sectional descriptive study was conducted on HIV/AIDS patients on ART attending Bombo Hospital in Tanga from July to October 2019. A non-probability, consecutive sampling technique was employed to obtain study participants. Data were collected using available data obtained from the patients' files, hospital record books and interviews of study participants by using semi-structured questionnaires. Data were entered into the computer using Excel 2013, cleaned and analysed using Epi Info version 7.2.2.6. Any p-value of < 0.05, at a 95% confidence interval was regarded as statistically significant. Results : The study showed that out of the 360 participants, 126 cases (35.0%) of OIs were reported. Pulmonary Tuberculosis had the highest prevalence of 18.0% among PLHIV while other opportunistic Infections altogether contributed 17.0%. Late ART initiation (OR=10.9, 95% CI: 6.5 ­ 18.3, p-value <0.001), Poor drug adherence (OR=19, 95% CI: 9.0 ­ 39.7, p-value <0.001), female gender (69% vs. 31%), which was however, not statistically significant (p-value ­ 0.904), Informal and Primary School education (OR = 1.6, 95% CI: 1.1 ­ 1.6, p-value 0.04) being married (OR=2.1, 95% CI: 1.3 ­ 3.4, p ­ value 0.004) and widowed/widower (OR=7.7, 95% CI: 1.7 ­ 33.7, p ­ value 0.007) respectively were found to be associated with OIs to PLHIV.CONCLUSION : The rate of OIs still high among PLHIV, Pulmonary Tuberculosis is the leading disease with 18.0% of all OIs symptomatic patients. Delay in ART initiation after positive test results, poor drug adherence and moderate malnutrition have been identified as major risk factors affecting 66.0%, 70.0%, 71%of PLWHA with OIs. We recommend early initiation of ART, Education on ART adherence and refilling of large quantities of ARV drugs to individuals working far from their homes.

Prevalence and Factors Associated With Hazardous Alcohol Consumption Among Motorcycle Taxi Riders in Kinondoni District, Dar-Es-Salaam, Tanzania: A Cross-Sectional Study.

BACKGROUND: Hazardous alcohol consumption is a significant public health problem contributing to road traffic accidents in nearly all countries. Despite the fact that motorcycles are involved in more than half of all road traffic accidents in Tanzania, little has been reported about hazardous alcohol consumption among motorcyclists. This study investigated the prevalence and factors associated with hazardous alcohol consumption among motorcycle taxi riders in Kinondoni District, Dar es Salaam. METHODS: A cross-sectional survey was conducted in Kinondoni District in August 2018 among motorcycle taxi riders. Multistage sampling was applied to select the study participants. Data were collected using structured self-administered questionnaires incorporating the Alcohol Use Disorders Identification Test. Analysis was done using IBM SPSS version 20. RESULTS: A total of 210 individuals participated in the study. Within the study sample, the prevalence of hazardous alcohol consumption was 61.5% (n=128). Hazardous alcohol consumption was positively associated with a positive family history of alcohol consumption (odds ratio [OR] 11.74; 95% confidence interval [CI], 5.14 to 26.79; P<.001). Protective factors were younger age (OR 0.09; 95% CI, 0.02 to 0.40; P<.001), having a secondary level of education (OR 0.21; 95% CI, 0.04 to 0.99; P=.034), having a primary level of education (OR 0.06; 95% CI, 0.01 to 0.26; P<.001), and being employed (OR 11.74; 95% CI, 5.14 to 26.79; P<.001). CONCLUSION: A high prevalence of hazardous alcohol consumption among motorcycle taxi riders was reported along with several associated factors. Interventions to mitigate hazardous alcohol consumption among commercial motor vehicle drivers must be developed and implemented.

Estimating and projecting HIV prevalence and AIDS deaths in Tanzania using antenatal surveillance data.

BACKGROUND: The Estimations and Projections Package (EPP 2005) for HIV/AIDS estimates and projects HIV prevalence, number of people living with HIV and new HIV infections and AIDS cases using antenatal clinic (ANC) surveillance data. The prevalence projection produced by EPP can be transferred to SPECTRUM, a demographic projection model, to calculate the number of AIDS deaths. This paper presents estimates and projections of HIV prevalence, new cases of HIV infections and AIDS deaths in Tanzania between 2001 and 2010 using the EPP 2005 and SPECTRUM soft-wares on ANC data. METHODS: For this study we used; the 1985-2004 ANC data set, the 2005 UN population estimates for urban and rural adults, which is based on the 2002 population census, and results of the 2003 Tanzania HIV Indicator Survey. The ANC surveillance sites were categorized into urban and rural areas on the basis of the standard national definitions of urban and rural areas, which led to 40 urban and 35 rural clinic sites. The rural and urban epidemics were run independently by fitting the model to all data and on level fits. RESULTS: The national HIV prevalence increased from 0% in 1981 to a peak of 8.1% in 1995, and gradually decreased to 6.5% in 2004 which stabilized until 2010. The urban HIV epidemic increased from 0% in 1981 peaking at 12.6% in 1992 and leveled to between 10.9% and 11.8% from 2003 to 2010. The rural epidemic peaked in 1995 at 7.0% and gradually declined to 5.2% in 2004, and then stabilized at between 5.1% and 5.3% from 2005 to 2010. New infections are projected to rise steadily, resulting in 250,000 new cases in 2010. Deaths due to AIDS started in 1985 and rose steadily to reach 120,000 deaths in 2010, with more females dying than men. CONCLUSION: The fact that the number of new infections is projected to increase steadily to reach 250,000 per year in 2010 calls for more concerted efforts to combat the spread of HIV infection particularly in the rural areas where the infrastructure needed for prevention programmes such as counseling and testing, condom accessibility and AIDS information is less developed.

Surveillance of HIV and syphilis infections among antenatal clinic attendees in Tanzania-2003/2004.

BACKGROUND: This paper presents the prevalence of human immunodeficiency virus (HIV) and syphilis infections among women attending antenatal clinics (ANC) in Tanzania obtained during the 2003/2004 ANC surveillance. METHODS: Ten geographical regions; six of them were involved in a previous survey, while the remaining four were freshly selected on the basis of having the largest population among the remaining 20 regions. For each region, six ANC were selected, two from each of three strata (urban, peri-urban and rural). Three of the sites did not participate, resulting into 57 surveyed clinics. 17,813 women who were attending the chosen clinics for the first time for any pregnancy between October 2003 and January 2004. Patient particulars were obtained by interview and blood specimens were drawn for HIV and syphilis testing. HIV testing was done anonymously and the results were unlinked. RESULTS: Of the 17,813 women screened for HIV, 1,545 (8.7% (95% CI = 8.3-9.1)) tested positive with the highest prevalence in women aged 25-34 years (11%), being higher among single women (9.7%) than married women (8.6%) (p < 0.07), and increased with level of education from 5.2% among women with no education to 9.3% among those at least primary education (p < 0.001). Prevalence ranged from 4.8% (95% CI = 3.8%-9.8%) in Kagera to 15.3% (95% CI = 13.9%-16.8%) in Mbeya and was; 3.7%, 4.7%, 9.1%, 11.2% and 15.3% for rural, semi-urban, road side, urban and 15.3% border clinics, respectively (p < 0.001). Of the 17,323 women screened for syphilis, 1265 (7.3% (95%CI = 6.9-7.7)) were positive, with highest prevalence in the age group 35-49 yrs (10.4%) (p < 0.001), and being higher among women with no education than those with some education (9.8% versus 6.8%) (p < 0.0001), but marital status had no influence. Prevalence ranged from 2.1% (95% CI = 1.4%-3.0%) in Kigoma to 14.9% (95% CI = 13.3%-16.6%) in Kagera and was 16.0% (95% CI = 13.3-18.9), 10.5% (95% CI = 9.5-11.5) and 5.8% (95% CI = 5.4-6.3) for roadside, rural and urban clinics, respectively. Syphilis and HIV co-infection was seen in 130/17813 (0.7%). CONCLUSION: The high HIV prevalence observed among the ANC clinic attendees in Tanzania call for expansion of current voluntary counselling and testing (VCT) services and access to antiretroviral drugs (ARV) in the clinics. There is also a need for modification of obstetric practices and infant feeding options in HIV infection in order to prevent mother to child transmission of HIV. To increase uptake to HIV testing the opt-out strategy in which all clients are offered HIV testing is recommended in order to meet the needs of as many pregnant women as possible.
