Diabetes Mellitus and HIV Study in Mwanza (CICADA)
2021年6月28日 更新者：Dr George PrayGod、National Institute for Medical Research, Tanzania
Diabetes and Associated Complications in HIV Patients
Emerging evidence from high-income countries suggests that diabetes mellitus is become a major health problem among HIV-infected patients.
However, due to differences in social, environmental, and genetic factors data from high-income countries can not be extrapolated directly to low-income countries.
This study investigates HIV, ART, inflammation, and body composition changes as risk factors for diabetes mellitus among HIV-infected patients in Tanzania.
調査の概要
詳細な説明
Access to antiretroviral therapy (ART) is increasing rapidly in low-income countries and HIV-infected patients initiate ART much earlier. As a result, these patients have prolonged life spans and, hence, longer HIV and ART exposure. Emerging data from developed countries suggest that HIV-infected patients have a higher risk than HIV-uninfected people of developing diabetes mellitus (DM) and other non-communicable diseases. The excess diabetes risk is probably related to multiple factors including HIV-associated inflammation, the use of some antiretroviral therapy (ART) regimens, and body composition changes associated with HIV and ART. As a result, HIV-infected populations may develop DM at a younger age and may have a higher mortality if management is not optimal as may be the case in resource-limited countries of Sub-Saharan Africa (SSA).
Most of the data to-date on HIV and DM are from high-income countries, and data in SSA are few and inconsistent. Because of differences in genetic composition as well as environmental factors including high burden of infectious diseases in resource-limited settings, data from high-income countries cannot be extrapolated and reliably used to improve quality of DM care among HIV patients in SSA. The objective of this study is to investigate if HIV, ART, and body composition changes occurring during ART use are associated with higher risk of DM as well as other risk factors for cardiovascular diseases in Tanzanian patients, and examine if HIV increases the risk of DM associated complications. This study is funded by the Danish Ministry of Foreign Affairs from 2016 to 2021.

調査対象母集団
A prospective cohort study with two annual follow-ups will be conducted.
This will be based on two existing HIV cohorts i.e.
Nutrition, Diabetes and Pulmonary Tuberculosis (TB)/HIV (NUT-TB) (NCT00311298) conducted in Mwanza from 2006-2009 and Nutritional Support for African Adults Starting Antiretroviral Therapy (NUSTART) ( PACTR201106000300631) conducted in Mwanza during 2011-2013 and a new HIV cohort which will be recruited at study initiation.
In the New HIV cohort, investigators will recruit both HIV patients and HIV negative participants who will act as controls.
These 3 groups will provide about 1900 participants with and without HIV infection to address study objectives.
説明
Inclusion Criteria:
- For existing cohorts, patients should come from NUT-TB or NUSTART Cohorts
- For New HIV cohort, patients should be HIV positive ART naive, HIV negative participants will be come from the same neighborhood as newly recruited HIV positive patients
- Age will be 18 years and above
- Mwanza region residency
- Not planning to relocate outside Mwanza within the study period
Exclusion Criteria:
- Very severe illness

HIV and Diabetes Cohort
Participants recruited in the study will have diverse characteristics.
Participants will either be HIV infected or HIV negative and among those HIV-infected there will be those on ART and those not on ART.
In addition, participants will have other background characteristics like having history of tuberculosis treatment, being malnourished while starting ART, having diabetes at ART initiation etc.
Investigators will also be able to examine the effect of immune activation, body composition changes, and other related factors on the risk of diabetes.
This diversity of characteristics will help provide adequate data to address study outcomes.

Combined prevalence of pre-diabetes and diabetes
時間枠：Baseline and follow-up (12 and 24 months)
|
The investigators will determine the combined prevalence of pre-diabetes and diabetes according to World Health Organization (WHO) diagnosis guidelines and investigate if behavioural and socio-demographic factors, and HIV, Tuberculosis (TB), ART, dyslipidaemia,chronic immune activation, parasitic infections, and body composition changes increase the risk of the outcome measure
|
Baseline and follow-up (12 and 24 months)

Prevalence of hypertension
時間枠：Baseline and follow-up (12 and 24 months)

The investigators will determine the prevalence of hypertension according to WHO diagnosis guidelines and investigate if behavioural and socio-demographic factors, and HIV, TB, ART, dyslipidaemia,chronic immune activation, parasitic infections, and body composition changes increase the risk of the outcome measure

|
Combined incidence of pre-diabetes and diabetes
時間枠：Follow-up (12 and 24 months)
|
The investigators will determine the combined incidence of pre-diabetes and diabetes.
The number of patients meeting WHO diagnostic criteria of pre-diabetes and those meeting WHO diagnostic criteria for diabetes will added together and become the numerator whereas participants who are not pre-diabetic or diabetic at the beginning of the observation period will constitute the denominator.
Investigators will determine if behavioural and socio-demographic factors, and HIV, TB, ART, dyslipidaemia,chronic immune activation, parasitic infections, and body composition changes increase the risk of the outcome measure
