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 a Sexually Transmitted Disease. It is generally found in men and women under the age of 25. Researchers have found that in the United States about 2.9 million individuals develop this disease every year. 

Here are things that you must know about the disease:

What is it all about?
It is caused due to bacterial infection and is transferred sexually. You can be infected with disease by having vaginal, oral or anal sex with the patient. You must be aware of the fact that you can develop chlamydia even if your partner doesn t ejaculate inside your vaginal tract. If you had suffered from this disease in the past, you can still get it again by having unprotected sex with an infected person.

What are the symptoms of this disease?
There aren t any obvious symptoms for this disease. Most of the patients show no sign of developing this disease. Thus, you never get to know when you were infected actually. However, some patients do reflect some symptoms after 4 to 5 days of infection. These symptoms include abnormal penis or vaginal discharge and painful, burning urination. Men can also develop a bleeding rectum.

How do you know for sure that you are infected?
Well, you can get yourself tested to confirm about the infection.

What happens if you don t get treated?
If the patient doesn t seek medical help, he or she is posing threat to his or her health. Women may develop pelvic inflammatory diseases, infertility or ectopic pregnancy. In men, it can cause pain and fever as the infection spreads along the tube carrying sperm.

Is there any treatment?
This disease is curable. But it is important to avoid sexual contact with anyone during the period of treatment or medication. First, you need to undertake the test to confirm the infection. You shouldn t have sex for seven days after the treatment is over. It is advisable to get yourself tested thrice in a year.

Chlamydia - Things You Must Know About It!

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.

Symptoms of Chlamydia and Ways to Treat the Disease

The HIV (human immunodeficiency virus) is a critical disease. This virus invades a person's immune system which is the body's defense against infections such as viruses and bacteria. The immune system doesn't work properly and becomes deficient once attacked by HIV. One social acknowledgement to HIV that has gained enough recognition is the HIV counselling due to the crucial need to counsel the patient about sexual behavior and the risks associated with it. 

Importance of HIV counselling 
The human immunodeficiency virus has become an epidemic in nature and has reached to a distressing proportion worldwide as it is in its third decade. Thus, counselling becomes remarkably crucial part of the treatment. 

HIV prevention counselling is a significant mode of behavioral invasion particularly in the deficiency or lack of an effective curative treatment or vaccine. HIV counselling varies from other forms of counselling sessions. Apart from being a health obstacle, the disease is equally overwhelming for the family as well as people around you. family. It is also connected with endless and intense human suffering which stimulates multiple emotional responses. Such reactions involve self-denial, grief, fear, loss, anxiety, anger, annoyance, depression self-blaming, pity, self-condemnation isolation and suicidal thoughts. 

Also, the risk of passing the virus to the partner during sexual activity is high and the patient must be aware of safe sex and the risks associated with unprotected sex. Hence, counselling becomes paramount. 

Counselling session s information Self-care counselling: 
The patient must be well informed about the disease and should be supported in embracing attitudes, actions, and beliefs which will defend and serve as a protective shield to the body s immune system. Improving, enhancing, and transforming nutrition is required. A few other things that are emphasized are, encouraging physical activity, avoiding objects, actions, and events that threaten the body, overcoming anxiety and stress that compromise the psychological, mental, physical and welfare of the body, and seeking and giving support for self-care. 

Types of counselling: 

Patient centered counselling: It changed the focus of counselling from a single informative one to one that concentrated on a patient s circumstances and needs. This involved active listening, to render better support and managing client's particular prevention needs. 
Risk reduction counselling: This includes examining client s awareness about sexual activity and their feelings.Using their current HIV knowledge as an appealing tool, the limitations they have for protected sex is discussed. A better understanding is ensured in the patients so that unsafe behaviors can be avoided. 
Grief counselling: People who are contaminated with HIV have an elevated risk of acquiring depression. Counselling helps you to deal with any emotional outburst. 
Aims of counselling in HIV infection-

Prevention is the first purpose of HIV counselling. It decides whether the lifestyle puts that individual at a higher risk. Helping to recognize and distinguish the definitions of high-risk behavior. The counselling contributes to behavioral change and also aims at working with the person and his family to obtain and sustain that change in approach and behavior.

HIV Counselling - Why It Is Important To Get It?

Spread of HIV infection from a woman who has transmits HIV to her child during pregnancy, childbirth (labor and delivery), or breastfeeding (breast milk) is called as  Mother to child  transmission (MTCT) of HIV. It is also termed as the perinatal transmission of the HIV infection or  vertical  transmission. In the absence of medical intervention, perinatal transmission rates are very high, between 20-45% in different parts of the world. In various regions of the African subcontinent a large number of HIV infected children are present. It is a major cause of deaths in teens and adolescents in that region. 

Almost 90% of all HIV infected children live in the sub-Saharan Africa. In some districts of AP, Karnataka, Maharashtra and TN that were highly HIV-prone, we have several HIV infected children and adolescents. The virus replicates in the body and affects the immune system. Due to decreased immunity, various opportunistic infections enter the body and cause AIDS related symptoms. Prevention of HIV infection in infants and young children is now a high priority and has been the rallying point for enhanced prevention efforts. MTCT HIV infection can be prevented with adequate measures by way of Anti-retroviral treatment (ART). All expecting mothers who are HIV infected should have access to the preventive medical services throughout the gestation period, during labor and also during breastfeeding. 



Proper provision of resources with skilled staff and awareness programs can help in avoiding new infection cases. Breastfeeding is the primary source of transmission of infection from mother to child. Basically, once ART is started in an HIV infected pregnant woman that should continue forever. With proper ART course, chances of MTCT are near Zero. At the Unison Medicare & Research Centre; which is India s first fully comprehensive clinic for HIV Care and infectious Diseases, during last decade, not a single MTCT has occurred after treating more than 160 such HIV infected mothers. Even prior to that MTCT rate was lower than 1%. Our motto has been making the mothers virally suppressed commensurate with the global principle of  Undetectable = Untransmittable ! In fact now more and more HIV infected couples have been coming forward for an elective pregnancy. Even HIV un-infected children orphaned by AIDS or living with sick caregivers are at the great risk of emotional and physical abuse, which in turn increases the child s vulnerability to HIV infection. 

Reduction of risks to these vulnerable children is of great importance and various programs are being implemented for the welfare of orphans and vulnerable children. Various risk factors that are implicated in the transmission of HIV infection from mother to child are as follows: 

Increased viral load 
Genital tract viral load 
Reduced CD4 cell count 
Unprotected sexual intercourse with infected partner 
Smoking, Substance and drug abuse 
Deficiency of Vitamin A and other essential nutrients 
Presence of other Sexually transmitted diseases (STDs) 
Pre-term delivery 
Placental disruption 
Invasive monitoring of the fetus 
Breast feeding In most cases, HIV will not cross through the placenta from mother to baby. 
In an otherwise healthy mother, risk of child getting infected is low. Prenatal visits shouldn t be increased until a complication arises. The physician should observe symptoms of AIDS and pregnancy-related complications on a regular basis. HIV may be the direct cause or a marker of a complex interaction of related medical and social conditions that affect pregnancy. Most HIV positive women are usually asymptomatic and have no major obstetrical problems during their gestation period. They should receive similar obstetric antenatal care as the HIV-negative women, unless indicated by the need to provide specific treatment for HIV related conditions. There is no evidence of a need to increase the number of antenatal visits, provided there are no complications of the HIV infection, although additional counseling sessions may be required to reassure the mother and family. 

Care of the HIV positive woman during pregnancy should include ongoing counseling and support as an integral part of the management. Invasive diagnostic procedures, such as chorionic villus sampling, amniocentesis or cordo-centesis should be avoided wherever possible, due to a possible risk of infection of the fetus.

How Can We Achieve HIV-Free Generation?

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.
