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!

Oral sex is a form of sexual activity, which involves the arousal of one's genitalia by his/her partner using the mouth (tongue, lips and throat). It is also called Cunnilingus (performed on a female) and fellatio (performed on a male). It is done before intercourse and during foreplay for sexual arousal. It is safe as compared to vaginal or anal sex, the rate of getting a sexually transmitted disease or HIV is comparatively lower. 

Oral sex can spice up your life and can also make your partner reach orgasm. It is also a safe way of getting sexual pleasure without getting pregnant. But necessary precautions must be taken in order to have safe oral sex.

Some of these necessary precautions are:

1. You can get throat cancer from oral sex: Human papillomavirus (HPV) is a cancerous virus found in the body of infected people. This virus can be transmitted to the person with whom you are engaging in oral sex. Studies show that people who engage with more than 6 sexual partners at once are more prone to get oral cancer. It is advisable to get your partner tested for HPV virus before engaging in oral sex.

2. Oral sex also causes stress: Oral sex is generally related to hygiene, therefore the partner can be self conscious and worried about his/her genital hygiene. If oral sex is performed on a daily basis, some people prefer to wax their pubic hair often. This is harmful because it can cause red bumps and burning sensation occurs. It is advisable to trim your pubic hair and wash it properly before engaging in oral sex.

3. A condom should be worn by the male during oral sex so that there is no risk of male fluid entering the woman's body.

4. A latex, which is made into a thin sheet called dental dam can be used on the vagina or anus. This creates a thin barrier between the mouth and the genitalia. Hence, chances of getting infected by sexually transmitted diseases are greatly reduced.

Oral sex can be pleasurable and fun, but the risks of getting sexually transmitted diseases like herpes, gonorrhea and crabs is not altogether misplaced. So it is advisable to use proper protection and to maintain hygiene before engaging in oral sex.

4 Ways to Have Safe Oral Sex - Necessary Precautions


- 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

An STD or sexually transmitted disease is usually an infection which spreads from one person to another during sexual contact. Some STDs can also be transferred through touch, since they spread by skin contact. People hardly like to talk or discuss about STDs, but it is very important to rule out the possibilities of STD. Whether one likes it or not, if STD testing is ignored, then it can lead to long term consequences.

Why STD Testing is Important

Often STDs have no signs and symptoms, and the only way to know that are you suffering from an STD is to get tested for it. So it is a good idea to get yourself tested, as you never know if you might have STD even though you don't show symptoms. Also, when STDs are diagnosed, most of them can be cured.

Consequences of Not Getting Tested

If one has STD and is not getting tested for the same, then it could lead to health problems which can cause permanent damages or might prove to be fatal. Some of the problems are:

1. Undiagnosed and untreated STDs can lead to damaged reproductive system, leading to sterile men and women. 
2. Chlamydia, if untreated can lead to epididymitis and shrinkage of testicles and infertility in men. It also leads to pelvic inflammatory disease. But good news is, it can be treated easily.
3. Syphillis can make a person blind and deaf, and can also be passed on to babies. 
4. Gonorrhea, which can also be treated easily with antibiotics, can lead to infertility or death if untreated. 
5. Even HIV/AIDS if diagnosed in early stages can enable the patient to lead a normal life and does not mean only death, contrary to conventional perceptions.  

Symptoms of STD

While, gonorrhea, chlamydia and human papilloma virus (HPV) have no symptoms, the common symptoms of STDs might vary. 

1. In women, the common symptoms are pain and burning sensation during urination, blood in vaginal discharge as also abnormal vaginal discharge, abdominal pain, blisters, warts, and swollen glands. 
2. Men often experience inflammation of the testicles, prostate, sores, fever, urethral discharge and pain during urination.

If these symptoms are observed, it is vital to get tested for STDs. Also the best way to protect your partner is not to practice unsafe sex and to refrain from the same until diagnosed and treatment is complete.
 
Getting yourself tested for STD is also beneficial, as it can prevent against complications like cancers and infertility. The standard STD panel of tests consists of Herpes IgG antibody and HIV antibody blood tests, along with a blood test for syphilis antibody and DNA urine test for gonorrhea and Chlamydia.

The Dangers of Putting Off STD Testing

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

One of the most common physically transmitted diseases is chlamydia. Chlamydia is a type of infection caused by the bacteria "Chlamydia trachomatis". The symptoms of Chlamydia are similar to the symptoms of Gonorrhoea (a bacterial sexually transmitted infection). Chlamydia infection causes permanent fallopian tube damage in women, leads to future ectopic pregnancy (the fertilised egg attaches itself outside the uterus) and infertility.

Symptoms of Chlamydia 
Men and women afflicted with chlamydia exhibit different symptoms.
The symptoms of chlamydia in women include:
1. Abnormal, sometimes foul-smelling, vaginal discharge
2. Bleeding between menstrual cycles
3. Painful periods
4. Abdominal pain, accompanied with fever
5. Pain during intercourse
6. Burning or itching around or in the vagina
7. Painful urination

Men usually display the following symptoms if they have chlamydia:
1. Minimal amounts of cloudy or clear discharge from the head of the penis
2. Painful urination
3. Itching and burning around the slit of the penis
4. Swollen and painful testicles

Treatment options available
1. Chlamydia is diagnosed by taking a swab from the cervix (in women) or the urethra (in men). These swabs will be sent to the laboratory for analysis. Urine samples can also be taken to check for the appearance of bacteria.

2. Since chlamydia is a bacterial infection, it can be easily treated with antibiotics. Oral antibiotics such as azithromycin or doxycycline are commonly prescribed by doctors. Azithromycin is usually prescribed in a large, single dose. The dose may also be stretched out for five days. Doxycycline is taken two times daily for a week.

3. With the right antibiotic therapy, the infection will clear up in 1 to 2 weeks approximately. It is very important that you finish the medication course if you wish you heal completely without having to suffer from further bouts of this disorder.

4. Women with critical chlamydia may need hospitalisation, pain medicine and IV (intravenous, or directly through the vein) antibiotics. Pregnant women with chlamydia infection can be safely cured with antibiotic such as erythromycin ethylsuccinate, amoxicillin and azithromycin.

Your partner needs testing and treatment as well to avoid further spread and reinfection. It is vital not to engage in any sexual activity while the treatment is ongoing. A further retest should be done three months later to make sure the infection is rectified.
