Lipid Profile and Diabetes Mellitus in People With HIV
Lipid Profile and Diabetes Risk of HIV Patients Treated by Austrian HIV -Physicians: a 7 Year Follow up Study
Study Overview
Status
Detailed Description
Background: In developed countries, an increase in cardiovascular events and related mortality has been seen; even more prominent in people living with HIV (PLWHIV) as compared to non-HIV control groups. Studies have shown dyslipidaemia and diabetes mellitus type 2 as important risk factors for cardiovascular diseases in PLWHIV.
The original study by this group in 2014 was a cross sectional study into the prevalence of cardiovascular risk factors (dyslipidaemia and diabetes mellitus) in PLWHIV in Austria and identified characteristics associated with these two risk factors. In that previous study dyslipidaemia was diagnosed in 46.3% of cases and half of all the study participants showed an increased insulin resistance. Eight persons (1.6%) fulfilled the criteria for diabetes mellitus type 2.
Purpose: The aim of this follow up study is to see the progression of our study sample and to see what prevalence levels may be found after 7 years. Additionally, a look into previously identified characteristics associated with dyslipidaemia and diabetes mellitus type may provide valuable insight into the temporal effects. Finally, examining resource use this population in terms of medications can provide insights into current practice and its associated costs in Austria, as well as an estimate of the added medication cost of dyslipidaemia and diabetes mellitus type 2 in this population.
It is our aim to close the existing knowledge gap on the role of dyslipidaemia and diabetes mellitus on cardiovascular risk among PLWHIV in Austria. Therefore, the investigation will be carried out by using routine data within minimum additional effort to the study team. The data obtained may serve as a base for future decisions on treatment of the Austrian HIV population.
Study details: Our epidemiologic evaluation documents real life major cardiovascular risk factors of HIV-infected patients, focusing on lipid profiles and diabetes mellitus risk. The gathered data from approximately 450 originally enrolled patients will be compared with the baseline values analysed in the original study in 2014.
Data collection: Dataset definitions and the minimum dataset will be determined by the study authors. Parameters used and documented must match those that were taken in the original study. These were specified in the case report form (CRF). The data collection and preparation will be done by a student of the Medical University of Vienna (Department of Social and Preventive Medicine) as a part of the graduate thesis.
Enrolment Strategy: Patients will be recruited through the original study sites (2 extramural HIV clinics in Vienna). Original patient lists will be screened through the official Mortality Register of the Statistics Austria, where patients who have died during the follow up period will be identified. Additionally, other patients who decline participation will be asked to give reasons of declining participation.
Data Validation and Data quality: Accurate data are crucial contributors to informative statistical analyses. Missing data will not be systematized.
Quality Control: Source documentation and data accuracy will be verified by site visit(s) in 1 randomly selected site after termination of the enrolment period. 10% of case report forms of the reviewed site will be randomly selected for monitoring.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in dyslipidemia prevalence from baseline - total cholesterol
Time Frame: 7 years
|
Total cholesterol values will be analyzed by an authorized laboratory
|
7 years
|
Changes in dyslipidemia prevalence from baseline- triglycerides
Time Frame: 7 years
|
Triglyceride values will be analyzed by an authorized laboratory
|
7 years
|
Changes in dyslipidemia prevalence from baseline - HDL-cholesterol
Time Frame: 7 years
|
HDL-Cholesterol values will be analyzed by an authorized laboratory
|
7 years
|
Changes in dyslipidemia prevalence from baseline - Apolipoprotein B
Time Frame: 7 years
|
Apolipoprotein B values will be analyzed by an authorized laboratory
|
7 years
|
Changes in dyslipidemia prevalence from baseline - LDL-cholesterol
Time Frame: 7 years
|
a. LDL will be calculated using the Friedewald formula.
As the Friedewald formula does not work in case of triglycerides > 300, in these patients only non-HDL-C will be used.
|
7 years
|
Changes in dyslipidemia prevalence from baseline - Non-HDL-Cholesterol
Time Frame: 7 years
|
Non-HDL-Cholesterol will be calculated additionally.
|
7 years
|
Changes from baseline in diabetes mellitus type II prevalence
Time Frame: 7 years
|
The diabetes mellitus prevalence will be assessed through patient history (checking for a diabetes mellitus type II diagnosis since baseline)
|
7 years

---|---|---|
Description of risk profile for cardiovascular events in the sample population
Time Frame: at follow up recruitment, Day 0
|
The cardiovascular risk will be assessed through the European Society of Cardiology (ESC) calculator.
Therefore, the risk profile for cardiovascular events will be assessed through documentation of risk factors (sex, age, smoking status, history of diabetes, hypertension, dyslipidaemia, previous cardiovascular events, other comorbidities) and laboratory parameters on the CRF by the investigator.
|
at follow up recruitment, Day 0
|
Changes from baseline in drug utilization for PLWHIV
Time Frame: 7 years
|
Drug utilization will be assessed through documentation on the CRF by the investigator
|
7 years
|
Prevalence of diabetes mellitus type 2 in correlation to the prescribed antiretroviral regime during the follow up time
Time Frame: 7 years
|
Diabetes mellitus type 2 will be assessed from patient history
|
7 years
|
Changes from baseline in the lipid profile of patients in correlation to prescribed antiretroviral regime
Time Frame: 7 years
|
Lipid profile will be assessed with laboratory parameters (total cholesterol, triglycerides, HDL, Apolipoprotein B).
LDL will be calculated using the Friedewald formula, additionally, non-HDL-Cholesterol (Non-HDL-C) will be calculated .
As the Friedewald formula does not work in case of triglycerides > 300, in these patients only Non-HDL-C will be used.
|
7 years
|
