The complex relationship between CD4 count, HIV viral load, .. isolate the immunological effect of a low CD4 count , the presumed goal of. The purpose of this study is to determine the relationship between South Africa assessed the change in CD4 count and viral load among HIV. The main goal of HIV drugs is to reduce viral load as much as possible for as long CD4 counts and viral load tests are usually done when you first see a new Blood chemistry tests are usually done a couple of times a year.
If a strain that is resistant to your HIV drugs develops, the virus will be able to grow even though you are on medication. Your viral load will start to rise.
CD4 vs. Viral Load: What’s in a Number?
The resistant virus soon will become the most common strain in your body. Complete blood count CBC This test looks at the different cells in your blood, including red blood cells, platelets, and white blood cells. Red blood cells carry oxygen to other cells in your body.
If the level of your red blood cells is too low, you have anemia. Anemia can lead to fatigue. Tests looking at your red blood cells include red blood cell count, hemoglobin, and hematocrit.
Platelets help with clotting, so if your platelets fall too low, your blood may not clot well. You may bleed more than usual, for example, when you brush your teeth or shave your skin. As the platelet count falls, the chance of internal bleeding rises.
White blood cells come in many types, and all are involved in your immune system's effort to keep you healthy. High white blood cell counts may indicate that you are fighting an infection. Low counts may put you at risk of getting an infection. These tests are usually done every 6 to 12 months, unless your lab values are fluctuating a lot, or you have symptoms of infections associated with HIV disease.
Then the tests are done more often, every 3 to 6 months. Blood chemistry tests Chemistry tests examine the levels of different elements and waste products in the blood and help determine how well different organs are functioning. Usually, the tests are divided into two panels: Electrolyte tests sometimes called "lytes" and kidney function--These tests help measure how well your kidneys are working, and measure the balance of fluids, acids, and sugar in your body.
They include tests for sodium, potassium, chloride, magnesium, blood urea nitrogen BUNcreatinine, and glucose.

Liver function tests LFTs --These tests measure whether your liver is being damaged. Things that can damage the liver are viral hepatitis, alcohol, medications, and street drugs. It is important to have a baseline measure of your liver health, because you may need to take HIV medications in the future, and some of these medications can cause liver damage. Blood chemistry tests are usually done a couple of times a year.
Fasting lipid profile The level of certain fatty substances in the blood can give clues to your risk of heart disease.
Triglycerides and cholesterol are important for health, but too much of them in the blood can cause fatty deposits to form in the arteries. This increases the chances of a heart attack. Too much triglyceride can also lead to pancreatitis, a serious inflammation of the pancreas. High cholesterol and high triglycerides can occur in people living with HIV for many years.
They can also be a side effect of HIV medications. Cholesterol is measured by three different tests: Your provider may want the lipid panel to be done while you are fasting, which mean nothing to eat or drink except water after midnight the night before the test. This gives the most accurate evaluation of the cholesterol and triglycerides in the blood.

Be sure to ask your provider if the blood tests are recommended to be done fasting. Most people who are exposed to TB don't get sick--the bacteria can live in the body for a long time without causing disease.
You can be tested for exposure to TB with several different tests. One is the TB skin test also known as PPDwhich requires a return visit days after the skin test is placed for an interpretation. Received Apr 10; Accepted Aug This article has been cited by other articles in PMC. HIV is an incurable chronic illness, making quality of life paramount. The direct relationship between quality of life and CD4 count is unclear. The purpose of this study is to determine the relationship between change in CD4 count and quality of life measures in a Ugandan cohort of people living with HIV.
Generalized estimating equations were used to analyze the data.
The primary predictor variable was change in CD4 count, and the outcome was quality of life scores. We controlled for sociodemographic characteristics, clinical factors and behavioral factors.
Twenty in-depth interviews were conducted to assess patient perception of quality of life and factors influencing quality of life. There was no association found between change in CD4 count and quality of life scores at univariate and multivariate analysis among the study participants whether on or not on antiretroviral therapy. Participants perceived quality of life as happiness and well-being, influenced by economic status, psychosocial factors, and health status.
Conclusions Clinicians and policy makers cannot rely on change in immunological markers to predict quality of life in this era of initiating antiretroviral therapy among relatively healthy patients.
In addition to monitoring immunological markers, socioeconomic and psychosocial factors should be underscored in management of HIV patients. Background There is an established relationship between immunological and virological outcomes as important markers of HIV disease progression and treatment failure [ 12 ]. CD4 cell count has been reported to have a strong association with progression to AIDS-related illness or death [ 3 ].
Quality of life QoL has become an important outcome variable to be monitored, in addition to other clinical outcomes and biological markers such as CD4 count [ 4 ]. With the prolonged survival of HIV patients in resource-limited settings, the focus in HIV care is no longer only on clinical outcomes such as morbidity and mortality but on QoL as well. QoL measurement is now more essential than ever, to optimize patient outcomes [ 4 ].
However, it is not clear how QoL and CD4 count are related, with few studies and inconsistent results. Understanding the relationship between immunological response and QoL will improve the effectiveness, receptiveness and accuracy of care and other support services to PLHIV in resource-limited settings.
Some studies have looked at factors associated with QoL, including CD4 count in developed and developing count [ 5 — 12 ].
Baseline CD4 count has been found to be a predictor of health-related QoL [ 14 ]. Another cross-sectional study reported that improving CD4 count is likely to also improve health-related QoL [ 15 ].
