Tuberculosis is an opportunistic infection caused by the bacteria Mycobacterium tuberculosis. The infections occurring in people with weak immunity as compared to the people with a healthy immune system are called as opportunistic infections. As, HIV enters the human body, it replicates and weakens the immune system which in turn increases the risk of contracting Tuberculosis in people already suffering from HIV infection.

An HIV and Tuberculosis co-infection occurs when an individual has both, the HIV infection and an either latent or active TB disease simultaneously.  Each disease acts in speeding up the progress of the other, when HIV and TB infection is present together in the body. HIV infection speeds up the progression from latent to active Tuberculosis, Mycobacterium tuberculosis also accelerates the progression of replication and spread of the HIV infection.

HIV infection and Tuberculosis are totally different type of infectious diseases. HIV is a viral infection and TB is a bacterial one. An HIV infected person will not contract TB unless a contact happens with a TB infected person. TB spreads via droplet infection and is communicable. If a person lives in a country with a high prevalence rate of TB, an HIV patient is highly susceptible to contracting the infection. In the similar manner, a person suffering from TB gets infected with the HIV infection only through the blood and bodily fluids borne route, with unprotected sexual intercourse with an HIV infected individual being the most important cause.

Amongst all the other opportunistic infections, TB occurs at an earlier stage in the course of an HIV infection than most other opportunistic infections. Mortality rate in the co-infected patients is more than twice that of HIV infected individuals without a TB infection. Even if a patient is undergoing anti-retroviral therapy, the death rates remain high in co-infected individuals.The natural history and course of TB gets altered in people with an infected immune system. The damage to immunity due to HIV infection causes a drastic reduction in the pathogen killing capacity of the body. In such patients if there is no anti-retroviral treatment prescribed, then the latency period between the infection and progression of disease gets eliminated. 

An active phase of TB is observed in such individuals progressing within a short span of time, ranging from weeks to months, rather than years as it normally should be spanning. Risk of progression from a latent stage to an active stage of TB is around 10-15 times greater in an HIV infected individual as compared to the non-infected person. Such individuals also communicate the disease more rapidly to others.Pulmonary tuberculosis in an HIV infected person can present similar symptoms like that of a classic TB disease. However, a co-infection can sometimes show less presenting TB symptoms, where even the chest X-ray scans can be observed to be normal. A  subclinical  phase of Tb in co-infected patients can cause delay in the diagnosis of the symptoms and subsequently affect the prognosis due to lack of timely treatment.

Social stigma and discrimination has caused an obstacle in provision of adequate treatment for people with HIV. Proper counseling  and initiatives taken to provide indiscriminate care can aid in identification of co-infection and earlier stages. Anti-retroviral treatment teamed up with anti-tubercular drug regimen is prescribed and a successful treatment for drug sensitive cases of TB can be provided with medications for 6-8 months.

How HIV & TB  Are Related?


- hiv testing in pregnancy should be done early so as standard care can be taken for the pregnant women.


- this hiv testing must be repeated in the third trimester, usually before 36 weeks of gestation. This should be done in women with hiv-seronegative and also in pregnant women who are at a high risk of developing hiv infection.


- expedited hiv tests should be performed at the time of delivery and labor and this is a must in women who have not been documented for hiv. The results of the test should be available in one hour of the test and the testing should be available 24 hours. In case the results are positive then, infant postnatal antiretroviral and intrapartum drug prophylaxis should be started immediately.


- women who have not been able to be tested for hiv at the time of labor and delivery are suggested expedited screening for hiv. Their screening can be done immediately postpartum or their babies should undergo screening. In case the infant and mother, both are positive, then infant antiretroviral drug prophylaxis should be started immediately. These mothers should avoid breastfeeding their babies, until the supplemental hiv tests are negative. In infants with positive hiv, prophylaxis should be discontinued and antiretroviral drug therapy should be started.


- in case of acute hiv infection during pregnancy, that is in the intrapartum period, or during breast feeding, initial testing can be performed with an antigen/antibody combination immunoassay. If the supplemental test is negative, then an additional test which is the virologic test (dna, rna) are necessary for the diagnosis of the hiv infection.
- if the mother is hiv positive then this information must be documented in the infant's medical record and also communicated to the infants care provider.
The knowledge of an antenatal maternal hiv infection allows the:
- women with hiv infection to get the correct antiretroviral therapy along with prophylaxis for the infections which might occur due to the immunocompromised state of the body. This also prevents and decreases the risk of transmission to their partners.
- when there is provision for antiretroviral therapy for the mother during pregnancy and labor along with antiretroviral drug prophylaxis for the baby there is less risk of perinatal transmission of the hiv.
- the hiv infected women should be counseled for a cesarean delivery. The option of an elective cesarean reduces the perinatal transmission of the hiv.
- the hiv women should be counseled about the risk of breastfeeding.

Identification and Management of Perinatal HIV Treatment

For nearly 30 years, HIV (human immunodeficiency virus) and AIDS (acquired immunodeficiency syndrome) have been shrouded in myths and misconceptions. In some cases, these mistaken ideas have prompted the very behavior that cause more people to become HIV positive. Here are the top five myths about HIV, along with the facts to dispute them.

Myth No. 1: I can get HIV by being around people who are HIV-positive.

The evidence shows that HIV is non communicable and does not spread through touch, tears, sweat or saliva. You cannot catch HIV by:

    Breathing the same air as someone who is HIV-positive
    Touching a toilet seat or doorknob handle after an HIV-positive person
    Drinking from a water fountain
    Hugging, kissing, or shaking hands with someone who is HIV-positive
    Sharing eating utensils with an HIV-positive person
    Using exercise equipment at a gym

You can get it from infected blood, semen, vaginal fluid, or mother's milk.

Myth No. 2: I can get HIV from mosquitoes.

Because HIV is spread through blood, people have worried that biting or bloodsucking insects might spread HIV. Several studies, however, show no evidence to support this, even in areas with lots of mosquitoes and cases of HIV. When insects bite, they do not inject the blood of the person or animal they have last bitten. Also, HIV lives for only a short time inside an insect.

Myth No. 3: I'm HIV positive, my life is over.

In the early years of the disease epidemic, the death rate from AIDS was extremely high. But today, antiretroviral drugs allow HIV positive people and even those with AIDS to live much longer, normal and productive lives.

Myth No. 4: My partner and I are both HIV positive there's no reason for us to practice safer sex.

Practising safer sex, wearing condoms or using dental dams can protect you both from becoming exposed to other (potentially drug resistant) strains of HIV.

Myth No. 5: You can't get HIV from oral sex.

It's true that oral sex is less risky than some other types of sex. But you can get HIV by having oral sex with either a man or a woman who is HIV positive. Always use a latex barrier during oral sex.

Top 5 Myths & Misconceptions About HIV & AIDS!

According to the tenets of Ayurveda, HIV is primarily a disease involving low immunity which is considered the most vital sap of the body. Immunity is in charge of providing both mental and physical strengths required to cope up with the foreign bodies that cause unwanted changes in the human body. When the immune system gets disrupted, the individual becomes susceptible to a host of infections and disorders. There are incessant numbers of bacteria and viruses in the environment, and some of them are highly contagious which can easily cause an infection.

Ayurveda has numerous highly effective therapies to combat HIV exposure. There is a sector of Ayurveda specifically dedicated to boosting immunity and vitality in the body with the help of herbs, minerals, and practice of Ayurvedic techniques. The treatment first aims to detoxify the body and strengthen the immune system which improves the immune system with the help of certain "rasayanic" techniques.

How is HIV exposure treated through Ayurveda?
The first step of HIV exposure treatment through Ayurveda is having nourishing food and leading a positive life supported by well-meaning friends and relatives. The patient can also take part in some physical exercises which don't cause any strain to the fragile health condition. Engaging in comfortable yet fruitful activities can help in strengthening good tendencies and stimulating appetite as well.

Then the patient will have to take some Ayurvedic tonics along with rejuvenators that can boost immunity levels and eliminate the toxins from the body. This is particularly done through emesis, purgation, and enemas. The medications which are given at this stage are neither drastic nor very harsh for the body so that they can be digested without any difficulty.

In the third stage of treatment, appropriate medications will help in purifying the blood, and this is where the role of liver corrective measures come to the fore. The patient has to take preparations with medicated ghee and soups that can alleviate the signs and symptoms of HIV exposure. There is no scope of consuming spicy and oily junk foods as they can take a toll on the patient s liver. Medicated alcohol may have to be used to aid in the digestive procedure and removal of blockages in the flow of energy.

Participating in physical activities on a daily basis is important. In case the patient is too weak to exercise or even run, then steaming can be helpful. This is very crucial since it is believed in Ayurveda that heated blood can weaken and sometimes destroy the virus involved in HIV.

There are some herbal cum mineral compounds which are helpful for subsiding the conditions of HIV exposure. It is important to consult with an expert who can evaluate your condition and help in healing the signs and symptoms that you are suffering from.

HIV Exposure - How Ayurveda Can Help You Manage It?

What is Monogamous Relationship?

You (who have been tested for STD/STIs and don't have any) are having sex with only one partner (who also has been tested for STD/STIs and doesn't have any) who only has sex with you. And you both keep it that way! 

Stated another way, you are both STD/STI free and only have sex with each other. People of any sexual orientation can engage in monogamous relationships. The only thing implied by the term monogamy is that the relationship consists of two people who are romantically and/or sexually exclusive. Theoretically, outside of abstinence, this is really the safest type of "safer sex" that you can have. 

Celebrated on 1st December of each year, World AIDS Day, aims to spread awareness about HIV / AIDs. It is an STD wherein, HIV stands for human immunodeficiency infection and AIDS stands for acquired immune deficiency syndrome. The disease hinders the immune system in keeping up our body s security against sickness. HIV causes individuals to end up wiped out with infections that regularly would not affect them and HIV leads to AIDS.

Understanding the Symptoms:

HIV has few or no signs or symptoms for up to ten years or more before side effects of AIDS tends to manifest. There is no cure for HIV/AIDS, yet treatment is accessible. A few people have HIV symptoms not long after being infected. These include:

There are a few phases of HIV illness. The primary HIV side effects may include swollen glands in the throat, armpit, or crotch.
Other early HIV symptoms incorporate slight fever, headaches, exhaustion, and muscle throbs.
These symptoms may keep on going for just a couple of weeks. At that point, there are typically no HIV indications for a long time. That is the reason it can be difficult to know whether or not a person is suffering from HIV.
The symptoms of AIDS show up in the most advanced phase of the HIV disease. These are as follows:

Along with a severely damaged immune system, a person with AIDS may likewise have thrush. A thrush is a thick, whitish covering on the tongue that is brought about by a yeast infection and now and then joined by a sore throat.
Serious or repetitive vaginal yeast infection.
Pelvic inflammatory illness.
Serious and frequent infections.
Unexplained fatigue that might be followed by headaches, dizziness.
Loss of more than ten pounds of weight that is not because of physical exercise or consuming fewer calories.
Risk Factors: There are a lot of ways in which you can get the infection. HIV is transmitted through blood, semen, vaginal fluids and breast milk. The most well-known ways in which HIV is spread, are:

Having sexual intercourse without a condom with somebody who has HIV/AIDS.
Using needles or syringes that have been used by someone who has HIV/AIDS.
Being punctured with a needle or surgical instrument that has been contaminated with HIV.
Getting HIV blood, semen or vaginal discharge into open injuries or wounds.
Babies born to women with HIV/AIDS can get HIV from their mothers during birth or from breastfeeding.
There are numerous ways in which you can protect yourself from HIV. These are as follows:

The most secure way is to limit the number of sexual partners you take on.
Try to have safer sex and always use protection.
Get your partners tested for HIV.
HIV tests are a typical piece of social insurance.
In case that you think you may have been infected by HIV, talk to a specialist or a doctor about testing. Discussing what risks you might have taken can help you choose whether testing is ideal for you.

This World AIDS Day - Let's Spread the Awareness About HIV/AIDS

HIV: QUICK FACTSIntroductionThe human immunodeficiency virus (HIV) is a subgroup of retrovirus (lentivirus) that causes HIV infection. After a period of time, this infection leads to what is called acquired immunodeficiency syndrome (AIDS).

Epidemiology

According to the Centers for Disease Control and Prevention (CDC), from 2010-2015, the estimated rate of HIV infection in all 50 US states decreased from 14.2 per 100,000 population in 2010 to 12.3 per 100,000 population in 2015. In 2015, 39,513 individuals were diagnosed with HIV infection. From 2010 to 2014, the annual number of new HIV infections decreased by 9%.

Virology HIV-1 and HIV-2 are retroviruses in the Retroviridae family, Lentivirus genus. They are enveloped, diploid, single-stranded RNA viruses with a DNA intermediate.Upon entry into the target cell, the viral RNA genome is converted into double-stranded DNA by an enzyme, reverse transcriptase that is transported along with the viral genome in the virus particle. The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase. HIV contains three retroviral genes, namely gag, pol, and env.

Gag gene: Encodes group-specific antigen; the inner structural proteins
Pol gene: Encodes polymerase; it also contains integrase and protease
Env gene: Encodes the viral envelope, the outer structural proteins responsible for cell-type specificity. Glycoprotein 120, the viral envelope protein, binds to the host CD4+molecule
Pathophysiology

HIV infects vital cells in the human immune system, such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells and leads to cellular immune deficiency. This results in the development of opportunistic infections and neoplastic processes.

Mode of Transmission
Sexual intercourse: Unprotected sexual intercourse; especially receptive anal intercourse and different sexual partnersContact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids infected with the virus.Spread from an infected mother to her infant through breast milk. An HIV-positive mother can transmit HIV to her baby both during pregnancy and childbirth due to exposure to her blood or vaginal fluid.

Signs and Symptoms There are 3 categories of infection 

Category A: Asymptomatic HIV infection without a history of symptoms or AIDS-defining conditions
Category B: HIV infection with symptoms that are directly attributable to HIV infection
Category C: HIV infection with AIDS-defining opportunistic infections
Investigation

A high-sensitivity enzyme-linked immunosorbent assay (ELISA) should be used for screening.

Management

Start with antiretroviral therapy (ART) in all HIV-infected adults ready to start therapy. 
CD4 count is no longer a criterion for starting the therapy.
Use of nucleoside reverse transcriptase inhibitors and protease inhibitors.
For refractory cases, during the failing treatment regimen and before switching therapy, use rapid confirmation, perform resistance testing and reevaluate.
