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.

HIV - Quick Facts Need To Know!

Chlamydia is one of the most common STD. It is a bacterial infection, caused by Chlamydia trachomatis. Occurring in both males and females, it can be transmitted via oral, genital, or anal sex. it has been dubbed as silent infection, as the affected person hardly ever presents with symptoms. It is extremely common though about 1 in 20 females in the age group of 15 to 25 can be affected. The disease, if left untreated, can cause severe reproductive issues including infertility in both males and females. Let us look at symptoms in men and women separately.

Men: About 50% of men infected with Chlamydia will go with no symptoms. It may take about 3 weeks for the symptoms to manifest and will include

    Small amounts of discharge from the penis
    Discomfort or pain with urination
    Painful, swollen, and inflamed testicles
    Burning and itching around the tip of the penis

Depending on the mode of transmission, the eyes, throat, and rectum can also be infected and there could be throat infection or conjunctivitis also.

If left untreated, Chlamydia can affect the sperm quality and lead to infertility in men in the long run.

Women: The infection is "silent" even in females and does not manifest itself with a lot of symptoms, only 30% of infected females present symptoms including:

    Abnormal, white or light yellow vaginal discharge
    Painful sex
    Bleeding or spotting in between regular periods
    Sometimes even bleeding during sex
    Burning or itching sensation around the vagina
    Severe abdominal discomfort
    Fever

In females, the infection usually travels up the urinary and reproductive tract. So, from vaginitis, it can lead to urinary tract infection, cervicitis, bartholinitis, and even pelvic inflammatory disease. If it reaches the fallopian tubes and/or the uterus, then the chances of fallopian tubes getting blocked is high. There can be scarring of the tubes and this can lead to infertility or ectopic pregnancy (pregnancy in areas other than the uterus, for example the fallopian tubes). This can be very dangerous and can be life-threatening situation too.

Pelvic inflammatory disease (PID) is a serious bacterial infection of the uterus and the fallopian tubes. Untreated Chlamydia infection often results in PID and requires antibiotics and bed rest.
Chlamydia infections have two negative sides to it, on one hand, it is difficult to detect given the absence of symptoms. On the other hand, there are serious implications leading to even fertility. It is therefore very important to prevent it. It is best to use a condom, especially with unknown partners; and in case of any doubt, one should get themselves tested and treated.

Symptoms of Chlamydia in Men and Women

A couple of decades ago, medical professionals believed that a lot of females could not climax at all. There are a number of reasons for this. It is easy for the male to know when he has achieved an orgasm, which usually happens with ejaculation, which is quite evident. For the females, on the other hand, it is not so evident. It is a perceived feeling and while the media showcase it in a particular way, reality is far moved from it.
There are various reasons why it is very difficult to pin this down. Orgasms are not just an elusive feeling for the woman, it is an elusive topic for the medical professionals too. Read on to know some of the common causes (more beliefs or notions) about this and some simple but effective ways of managing this.
- Private topic: Girls are very shy compared to boys and both their exposure to sex education and discussion about this is limited compared to boys. We might tend to think of it as common in India alone, but this is true across a vast number of countries. We are not alone! This shyness continues into their later years too, and unless transformed by the partner, it may continue to be a topic that is shunned.
- Purpose: Sex is more deemed as a form of procreation rather than for sex. Therefore, while sex is necessary for conception, orgasm is not. This is one more reason (strange but true) that orgasm is very elusive for a woman.
- Psychological factors: It could be guilt from past relationships or fear of past abuse. It could be fear of losing control or fear of coming across as vulnerable. For any of these reasons, women can have difficulties climaxing during the act.
In men, the causes are more defined and physical in nature and include erectile dysfunction, premature ejaculation, retrograde ejaculation, and delayed ejaculation.
Whatever the cause of the problem, the first step in coping up with the issue is to acknowledge the issue. Being a private topic, this is not something that is going to draw the person towards medical help. However, this needs to be discussed frankly with the partner or with the doctor. Getting the partner involved removes a lot of psychological barriers (guilt, fear, anxiety, etc.) This would result in natural ironing out of issues, improving the performance of both the people involved.
If that does not happen, seeking professional help, be it medical help to correct physical issues or counselling, is the next suggestion. A frank discussion will do wonders, and what was once elusive can be well within your reach.

The Elusive Orgasm - Causes and Coping!

HIV infection and AIDS (commonly referred to as HIV/AIDS) are caused by the Human Immunodeficiency Virus (HIV). HIV is transmitted sexually and through exchange of body fluids, such as blood. The HIV attacks our defense system (immune system) giving opportunity to many illnesses to attack the body. These infections (called opportunistic infections) range from common cold and diarrhea to life-threatening illnesses including uncommon pneumonias and cancers. The type, range and intensity of opportunistic infections vary with the severity of the HIV infection and the extent to which our immunity is compromised. 

AIDS is the last stage disorder of the HIV infection. Though there is no complete cure for the HIV-infection till date - despite thousands of scientists across the world working on it, spending countless hours of research involving billions of dollars - there has been tremendous progress in medicare improving the quality of life of the HIV-infected, in extending their life-span to almost normal levels and in preventing mother-child transmission. 

The key factors in extending the life-span, and in keeping good immunity and good health are 

balanced and nutritious diet

regular physical exercise

correct, consistent and lifelong use of the prescribed medicines

periodic medical checkups

staying psychologically positive and strong

good family support and

good lifestyle habits.

The last one involves maintaining good personal hygiene, avoiding smoking (active as well as passive), alcohol, recreational drugs, unhygienic and disease-prone environments and sedentary life style. Those who follow these will guidelines certainly have better prognoses. 

Diet:

A nutritious diet is of utmost importance to the HIV-infected, as adequate nutrition contributes to the development of the immune system, prevents malnutrition and wasting, achieves and maintains optimal body weight and strength, enhances the body s ability to fight opportunistic infections, helps delay the progression of HIV, improves the effectiveness of drug treatments, and improves the quality of life. 

Ensure that the food contains adequate macronutrients, that is, carbohydrates, proteins and fat, otherwise the patient may end up with - protein-energy malnutrition, manifesting itself in the weight loss and wasting that is typical of AIDS patients.

As per WHO, an HIV-infected person has additional nutrient requirements: 10-15 percent additional energy intake and 50 to 100 percent increase in protein intake as compared to a non HIV-infected person.

Consuming micronutrients (especially Vitamins A, B6 and B12, iron and zinc) is important for building a strong immune system and fighting infections.

Try and maintain a daily diet containing rice/roti, vegetables, legumes, and fruits which provide you energy and micronutrients. Choose foods that are low in saturated fat, trans fat, and cholesterol.

Eat at least two servings of fish each week. Oily fish, which contain omega-3 fatty acids, are best. If you cannot eat fish, you can also get omega-3 fats from omega-3 eggs, walnuts, flax seeds.

Better avoid fast foods.

Living with HIV/AIDS: Diet, Nutrition, and Food Safety

People who suffer from human immunodeficiency virus, commonly known as'hiv, are known as hiv positive people. The virus is the agent of aids that is currently incurable. Hiv is known to alter the human immune system and makes people much more susceptible and vulnerable to diseases and infections. 

Body fluids such as semen, blood, breast milk, vaginal fluids etc. Of an infected individual contains the virus, which can be passed from one person to another during blood-to-blood and/or sexual contact. Hiv positive women may even pass on this virus to their children during pregnancy, delivery or by breast feeding them. Hiv is also transmitted during oral, anal or vaginal sex, by contaminated hypodermic needles and by blood transfusion. 

Mentioned below are a few issues that a hiv positive woman have to face apart from discrimination and stigma, fear of infecting their children or partners, violence and abandonment. 

1. Menstrual disorders: changes in menstrual cycles are frequently reported by hiv infected women. However, menstrual dysfunctions are due to varied reasons that aren't directly related to the disease. Although most of the hiv positive women suffer from amenorrhea i. E. The unusual absence of periods, it is not just due to hiv but also because of weight loss or immunosuppression. 
 
2. Contraception: it is very important that the contraception a hiv positive woman chooses not only acts as birth control, but also to prevent the transmission of sexually transmitted diseases and hiv. Although condoms do not provide exceptional pregnancy prevention, they are excellent at preventing transmission of the hiv virus. Permanent sterilization is usually the most chosen contraceptive method for hiv serodiscordant couples.

3. Surgical complications: hiv positive women are at a higher risk of undergoing gynecologic surgery. This is because they are more vulnerable to pelvic infectious disease that requires surgical intervention. There is also a greater risk of developing vulvar cancer in hiv positive women. 

4. Fertility: there has been an increase in the number of seropositive women contemplating pregnancy and childbirth. Most couples resort to assisted reproduction to lower the risk of horizontal hiv transmission. Studies show that undergoing hiv treatment and having an undetectable viral load is helpful in preventing the transmission of hiv. It is important to consult a medical expert if you are unable to get pregnant after at least 6 months of trying. Fertility problems are more common in hiv positive women than hiv negative women.

Issues for HIV Positive Women

HIV or Human Immunodeficiency Virus is a type of immune disorder which attacks the immune system of the body and slowly destroys it overtime. The HIV virus targets the immune system and makes the body susceptible to other diseases. HIV infection can progress to AIDS although it may take up to 10 or 12 years to fully go into the last stage.

Risks and Causes
HIV is a communicable disease which spreads through only the following methods

    It can spread from one person to another by means of unprotected sexual intercourse due to the exchange of bodily fluids.
    The virus spreads if you share drug needles with someone who is already contaminated with HIV virus. It can also occur due to improperly trained medical staff that may reuse syringes although this is very uncommon.
    The HIV virus transmits from the mother to the child during pregnancy through the placenta.
    Any exchange of blood in significant amounts such as blood transfusion from a contaminated patient will result in infection as well although this is very rare.

Any other form of contracting the disease such as through kissing or food is a untrue and only propagates due to ignorance.

Symptoms
The initial symptoms of HIV infection are noticed after a few weeks although it can take a few months to come up as well. The initial symptoms may include
1. Severe headache along with intense pain in the muscles and the joints of the body.
2. Frequent appearances of rashes
3. inflation of the lymph nodes
4. Itchy skin
5. Disorders which stay for sustained periods such as an upset stomach or a cold.

The early symptoms disappear within 2 to 3 weeks without any treatment. The later symptoms might appear after few years (sometimes up to or more than a decade), which will stay. This is usually the time HIV is diagnosed. The symptoms now may also include
1. severe muscle fatigue
2. severe loss in body weight,
3. High fever and recurrent instances of sweating at the night time.
HIV is suspected if the later symptoms tend to last for a long time without any other diagnosable cause.

Treatment
HIV can be treated by means of antiretroviral therapy which reduces the rate at which the virus multiplies. However, there is no cure for HIV as of yet.
Prevention
In order to prevent yourself from getting HIV, you should adopt the following precautionary measures:
1. You should use protection every time when engaging in sexual intercourse and if you are unsure of your partner s HIV status.
2. You should use new blades in barbershops for shaving purposes in order to prevent yourself from HIV as well
3. If you are diagnosed with HIV/AIDS while you are pregnant, to prevent spreading it to your unborn baby, you might immediately need undergo a medical check-up and follow the doctor s advice.
4. Ensure that disposable syringes are used whenever they are being use for medical tests or treatments.
