What are the immunological and hematological changes in HIV infection?

The immunological changes include depletion in CD4+ T cell, cytokine dysregulation and immune dysfunction. The dominant immunologic feature of HIV infection is progressive depletion of the helper T cell (CD4+ T cell), which reverses the normal CD4:CD8 ratio and subsequently lead to immunodeficiency.

How does HIV affect hematology?

Anemia, neutropenia, lymphopenia, and thrombocytopenia are hematologic complications of HIV infection. Anemia is the most common hematological disorder that frequently occurs in HIV patients and it is an indicator of transition to acquired immune deficiency syndrome (AIDS) or death.

What labs are abnormal with HIV?

These include ALT (SGPT), AST (SGOT), LDH, alkaline phosphatase and total bilirubin. Elevated liver enzymes are caused by some medications. It can also be caused by liver disease such as hepatitis B or C, injuries and tumors. Abnormal LFTs are common in 60–70% of people with HIV, but liver failure is unusual.

What type of anemia is associated with HIV?

Background. Anemia (hemoglobin < 10 g/dL) and severe anemia (hemoglobin< 7.5 g/dL) [1] are common among people living with HIV (PLWH) [2], and the prevalence of anemia increases with HIV disease severity [3, 4].

What are the causes of leukopenia?

What causes leukopenia?

• Blood cell or bone marrow conditions. WBCs originate from the stem cells in the bone marrow.
• Treatments for cancer.
• Congenital disorders.
• Infectious diseases.
• Autoimmune disorders.
• Malnutrition.
• Medications.
• Sarcoidosis.

Why there is leukopenia in viral infection?

A person with leukopenia has a low number of white blood cells, or leukocytes, in their blood. White blood cells help fight infection in the body. A person with a low white blood cell count is more likely to contract an infection. Leukopenia usually involves a lack of neutrophils, which are a type of white blood cell.

What viral infections cause low WBC?

They help your body fight off diseases and infections. If you have too few WBCs, you have a condition known as leukopenia….Several infectious diseases that can cause leukopenia include:

• HIV or AIDS.
• tuberculosis.
• viral hepatitis.
• malaria.
• typhoid fever.

What causes leukopenia and neutropenia?

Neutropenia is associated with bacterial infections and a high fever, while leukopenia tends to be associated with viral infections, although these effects can occur with either condition. These conditions are diagnosed with a CBC blood test that measures the different types of white blood cells.

Do lymphocytes increase with viral infection?

For example, if you have a bacterial infection, you will have an increase of neutrophils and a decrease in lymphocytes. Conversely, if you have a viral infection, you will have a decrease in neutrophils and an increase in lymphocytes.

How does a CBC detect viral infection?

A simple and very informative test is the white blood cell “differential”, which is run as part of a Complete Blood Count. The white blood cell “differential” will usually tell you whether you have a bacterial infection or a viral infection.
