1. Lymphadenopathy: lymphadenopathy is the swling or enlargement
of lymph nodes caused due to infection, malignancy or autoimmune
disorders.
2. Polymorphonucleocytes : Polymorphonucleocytes are white blood
cells found in the blood that contains granulous cytoplasm and
polymorphic nucleus. Polymorphonucleocytes include neutrophils,
eosinophils, and basophils.
3. Leukopenia is the decrease in number of leukocyte count in
blood. It may be caused due to radiotherapy, chemotherapy,
autoimmune diseases, HIV , AIDS, dengue.
Leukopenia increases the risk for infection.
4. Anemia : Anemia is the decrease in red blood cells resulting in
reduced capacity of blood to carry oxygen to different parts of
body. Causes for anemia includes iron deficiency, folate
deficiency, vit B12 deficiency, blood loss, hemolysis, renal or
hepatic diseases.
5. Thrombocytopenia is the decrease in number of platelets in blood
below 150000 platelets/uL of blood. It may be caused due to hepatic
diseases, folate deficiency, vit B12 deficiency, leukemia,
dengue.
6. Immunodeficiency: Body immune system helps to fight against
pathogens and protect the body against various kinds of infection.
immunodeficiency is a condition characterised by weak immune system
of the body. This may be due to antibody production against self
cells or decreased immune system cells.
7. Retrovirus : retrovirus are type of RNA virus that enters the
host cell and attacks the DNA resulting in alteration of cell
genome. It produces its own DNA from the RNA with the help of
reverse transcriptase enzyme. Retrovirus have been found to be
oncogenic and cause cancer. The most common retrovirus is HIV1 and
HIV2 that causes AIDS.
8. Protease inhibitors are antiviral drugs that inhibits the
protease enzyme resposible for proteolytic cleavage of protein
precursors and thus prevent viral replication. Protease inhibitors
are used in treatment of many viral diseases such as hepatitis C,
AIDS and some types of malignacy.
Some of the protease inhibitors are indinavir, boceprevir
