CD5 is a unique protein which acts as a differentiator on the surface of various types of T cells and in a subset of B cells, specifically B-1a. The exact functionality and role of the CD5 protein as a receptor and differentiator is a controversial topic in the field of haematology and blood topology. As of now, there has been no consensus about its exact role as a receptor in human B-cells. Until recently, the CD5 protein was used as a marker for T-cells until the process of using monoclonal antibodies against CD3 were developed. The protein is present in higher concentration on T-cells rather than B-cells.
The CD5 protein is found in humans on the long arm of the 11th chromosome and is therefore widely available throughout the body. The steps for extracting the protein is through a simple blood test. Usually, about 2ml of blood is extracted for the test, and other tests can be performed with the same sample. The blood is taken from the vein near the elbow, hence short-sleeved clothing is expected to be worn. The process is nearly painless and takes less than a few seconds to complete. There are no dietary recommendations for this test, however, your doctor might inform you about certain dietary restrictions for other types of tests.
While the exact use of CD5 protein has not yet been discovered, it has been found to act as a marker for T-cells, however, they are not as sensitive as CD3. CD5 can be used to diagnose rare conditions such as mantle lymphoma and chronic lymphocytic leukemia. The absence of the protein can be considered as malignancy of the condition.
The process of extracting blood is fairly simple and common. It can be performed at any place which is clean and well lit. The process requires an expert hand, therefore it is not recommended that you try to do it by yourself. The usual process is as follows: A rubber nozzle is tied tightly near the biceps to thrust the veins towards the top near the elbow. The location is cleaned and de-sensitized by scrubbing it hard with some medicated alcohol. A hypodermic syringe is pierced through the skin and vein to extract the blood. Once the blood has been extracted, the needle is pulled out swiftly and the location is squeezed hard to allow the blood to coagulate.

HIV, which is short for Human Immunodeficiency Virus, penetrates your body and directly attacks your immune system. In this process, the virus weakens your body's natural defense mechanism against diseases and infections. A compromised immune system makes the body prone to minor infections, which healthy people would generally overcome. The virus itself doesn't cause any physical symptoms. It only serves to ease the entry of other bacteria and viruses into the body.
The following are some of the ways HIV affects your body:
1. Immune system - The human immunodeficiency virus destroys CD4 cells, the white blood cells that help the immune system ward off foreign substances. If left unchecked, HIV can develop into AIDS. During such time, the virus may damage the immune system to an extent that it wouldn't be able to ward off minor infections that a healthy immune system would. A person with HIV could thus suffer from fever, chills, sweats, shortness of breath, white spots in the mouth, fatigue, skin rash and weight loss from time to time.
2. Respiratory system - As HIV develops into AIDS, the body can contract infections such as pneumocystis pneumonia (PCP), tuberculosis and Kaposi's sarcoma. These conditions lead to serious respiratory problems. PCP is found to be one of the most common infections among people with HIV. 85% of the people would develop the infection if the condition is left untreated.
3. Skin problems - As in healthy individuals, many skin conditions can also occur in people with HIV or AIDS. But a compromised immune system heightens the condition and causes difficulty in treatment. Dermatitis, psoriasis, and hives are common conditions. They are also prone to a rare type of skin cancer known as Kaposi's sarcoma.

What are the causes, symptoms and treatment for HIV
HIV AIDS kaise spread hota hai, iske symptoms kya hai, iska treatment kaise karte hai, iske barey mein aaj hum baat karengey. HIV ek retrovirus hai jo usually sexual mode se transmit hota hai. Sexual mode ke ilawa yeh infected needles se bhi spread ho sakta hai yah infected blood transfusion se bhi spread ho sakta hai, aur lastly mother agar infected hai toh mother se child ko bhi aa sakta hai. Toh hum isko kaise diagnosis karte hai? Basically blood test se yeh pata chal jata hai, iske do tarah ke blood test available hai, ek se aap directly antigens ko detect kar sakte hai jaise p24 antigens yah aap directly antibodies ko detect kar sakte hai jaise ki ELISA aur western blot. Yeh test se malum ho jata hai ki patient HIV infected hai yah nahin. Agar HIV hai confirm honey ke baad patient ko hum stage kya hai pata karne ke liye further test karte hai jaise ki CD4 Count aur viral load keh ke do test rehte hai iske liye toh iske hisaab se patient ko hum 4 stage mein divide kar sakte hai stage 1, stage 2, stage 3, stage 4.
Agar stage 1 mein dekha jaye toh patient mein bilkul sympotoms nahin dikhte hai. 2nd stage mein patient ko khasi se chhotey motey bukhar aur skin infections jaise herpes infection jaise problems aa sakte hai. 3rd stage mein patient ko long term problems aatey hai jaise ki fever yah chronic lose motions jo ek mahine do mahine se zyada rehte hai aur jo dawa lene ke bawajud bhi kam nahin hota hai, yah patient ko agar tb ho jata hai, HIV patients mein 80% se zyada logo ko TB aa jata hai, toh yeh sab infections stage 3 mein aa sakte hai. Agar yeh stage mein bhi dawa nahin lete hai patient toh 4th stage yaani ki AIDS stage mein phuch jatey hai. Jismein ki patient ka CD4 count bohut kam hota hai, usually less than 100 rehta hai. Aur yeh stage mein patient ko opportunistic infections aa jaatey hai jaise ki TB, extrapulmonary TB, Lungs ke ilawa dusre jagah bhi aa sakta hai jo ki very common hai yeh stage mein.
Aur iske ilawa patient ko esophageal infections like fungal infections, oral candidiasis jaise problems aa sakte hai. Yah patient ko dusre malignancies aa sakte hai jaise lymphoma malignancies. Toh yeh stage pata karne ke baad humko kaunse treatment start karna hai iske liye hum anti retroviral treatment start karte hai jo ki HIV ko phailne se rok deta hai aur HIV ko khatam karne ke liye best treatment hai.
HIV treatment ko hum ART Treatment kehte hai. ART Treatment Government se bhi available hai aur private mein bhi available hai. ART treatment se kya hota hai, jo virus hai who kam ho jata hai. Iske wajah se hum cd4 ko badha sakte hai. CD4 count normal person mein 500 se le kar 1500 tak rehta hai, jo HIV infected rehte hai unka CD4 count kam ho jata hai. Patient ko dawa start karne se pehle counseling karte hai. Counseling mein hum patient ko iske dawa ka important effects kya hai batate hai.
Main important cheez hai dawa ko regular lena hai, isko rok nahin sakte, aise important cheez hum patient ko batate hai, aur patient ko motivate karte hai ki jo regular aap dawa logey toh apko koi bhi symptoms nahin ayengey, aur dawa lene se cd4 improve hoga aur immunity improve hoga, appetite badhega aur apka swasth thik rahega. Hum advice karte hai patient ko hamesha condom use karey aur agar aap ART treatment lete ho iske affect se HIV dusro mein phailne se rukk jata hai, to hiss tarah se humlog HIV ko prevent bhi kar sakte hai.
Aaj ke liye bus itna hi HIV ke barey mein. Agaar aap ko koi doubts hai yah apko treatment ke barey mein baat karna hai toh aap mujhe Lybrate se contact kar skte hai. Agar aap Hyderabad mein ho toh aap mujhe Srinivasa Hospital mein morning yah evening time mil sakte hai. Dhanyabaad.
Here are the symptoms , diagnosis , prevention & treatment of HIV
This is Dr. Ajay. Last time I spoke to you about HIV the symptoms, the staging and how to identify the patient with HIV phase down symptoms. So today in this video I will be discussing more about how to diagnose the patient with HIV.
What are the tests available? What are the treatment options available? And how to prevent HIV?
So when we come across the patient with HIV the only way we can diagnose the patient with HIV is by doing blood test. There are different kinds of blood tests available. They can be from the tests that detect the antibodies for HIV. There are tests to detect the antigens on HIV like P-24. Then there are tests to detect the virus itself like PCR. So when a patient is exposed the HIV positive patient either sexually or through injections. Then the patient develops antibodies in his body. So these antibodies take at least three to six months’ time to develop. So in this duration which is called as window period. In this period we won’t be able to detect antibodies. So all the tests like Elisa, Tridot, and Western blot. These tests won’t be able to pick up the patient’s window period when the antibodies are not there. So if you want to detect the antibodies you need to wait for three months or three to six months after exposure.
So if you can’t wait for three to six months you can do the other tests which can pick up the virus directly. So once we diagnose the patient with HIV then the next step would be to monitor the disease I mean how to stage the patient. So because HIV damages the immune system. So there are the tests which can assess the immune system of the patient so these tests are called cd4 count and viral load. CD-4 is nothing but it is a sub site of T-cell. So the normal CD count for a patient would range from 500-1500 which is a normal range. The other test which is available is viral load. The viral load is nothing but it detects how many viral copies are present in the body. After diagnosing the patient with HIV. The next step would be to start the treatment. So the treatment what we give for HIV is what we call is antiretroviral treatment or ART. ART is the most popular treatment available for treatment and in this ART there are different medicines available.
The most important thing which determines is the CD-count and the viral load. So before we start the antiretroviral treatment we assess the patient. First we counsel the patient whether the patient is prepared to start the treatment or not. Then we also rule out the other opportunistic infections. Because patients who have HIV already have other opportunistic infections. So before you start the antiretroviral treatment you need to assess whether the patient is having any opportunistic infection. You have to rule out those then you also have to assess the baseline function of the patient like whether the patient is having any liver abnormalities or if the patient is having normal liver function, normal kidney function and we also have to do the complete blood picture.
So if the patient is having all the parameters normal and if the patient is not having any opportunistic infection. Then we do preparedness counselling for the patient that is when we start the treatment. So before we start the treatment we see the CD-4 count. Now previously the guideline was to depend on the CD-4 count. They use to start the treatment when the CD-4 count is low but now the guidelines say that HIV treatment can be started irrespective of the CD-4 count.
So this is all about HIV treatment and in the subsequent video I will be talking more about the HIV treatment and I would like to thank lybrate and if you want to consult me you can consult me through lybrate or you can directly walk in or take an appointment and meet me at my clinic at Narayanguda.
