HIV/AIDS in INDIAN COUNTRY:Do we have a problem?

National Native HIV/AIDS Awareness Day

WHY ARE WE HERE?

To discuss the enormous risk for an HIV outbreak in one or more Indian communities

To underscore the new CDC recommendations for routine screening

Revised Recommendations for HIV Screening in Health-Care Settings

in the U.S.

CDC Recommendation for HIV Screening

Opt-out HIV screening and HIV diagnostic testing should be a part

of routine clinical care in all

healthcare settings.

September 22, 2006

This information is based on: Centers for Disease Control and Prevention (CDC). (2006, September 22). Revised recommendations for HIV testing of adults, adolescents, and pregnant women in health-care settings. Information take from: http://www.cdc.gov/hiv/topics/testing/healthcare

Individuals in the U.S. between the ages of 13 and 64 Patients receiving care for tuberculosis (TB) Patients in care for other sexually transmitted

diseases (STDs) Women who are considering conception and

pregnancy Women who are pregnant Women in delivery who have undocumented HIV

status at the onset of labor Infants born to mothers with undocumented HIV

status.

The CDC recommends that HIV screening be a routine part of health care for all:

BASIC TENETS OF DENTAL CARE IN THE HIV/AIDS PATIENT

Oral GuidelinesThe guidelines

for good oral health care are the same for HIV positive people as they are for all dental patients

Guidelines for Infection Control in Dental Health-Care Settings

Oral Manifestations of HIV Infection Oral manifestations may be among

the first signs of HIV infection and thus may lead to testing and diagnosis of HIV infection.

Oral conditions may develop as immunosuppression progresses, causing signs and symptoms that require management.

Treatment Planning For The HIV+ Patient Follows The Same

Guidelines As For Non-HIV+

Relieve pain Restore function Prevent further disease Consider esthetic

results

General Treatment Planning

Modifications of care for the HIV patient are similar to those of any medically compromised person.As an example, diabetics require special consideration

because of their impaired response to bacterial infections as well as delayed healing

General Treatment Planning Strong emphasis must be placed on prevention

Each patient is different and each treatment plan must be prioritized according to that patients health needs.Deviation from the

customary treatment sequence may be indicated

Early Stage

Patients with HIV who have a CD4 count above 200 are defined as being in the early stages of the disease.

These patients should be treated the same as HIV negative patients.

Late Stage

When CD4 counts fall below 200, patients are considered to have progressed to the later stages of the disease.

Most of these patients are still easily treated in the GP office, but occasionally require antibiotic prophylaxis for invasive procedures.

Antibiotic Prophylaxis

Indicated when:Neutrophils: <500 cells/mm3

According to AHA guidelines if patient has heart/valvular problems

Need for antibiotic prophylaxis is not based on CD4 count

Indicated when:Neutrophils: <500 cells/mm3

According to AHA guidelines if patient has heart/valvular problems

Need for antibiotic prophylaxis is not based on CD4 count

Antibiotic Prophylaxis

Patients with indwelling catheters such as a Hickman catheter may require antibiotic prophylaxis prior to dental care. Medical consultation may be warranted.

Renal dialysis patients with shunts for hemodialysis require antibiotic prophylaxis prior to invasive dental care.

Patients with indwelling catheters such as a Hickman catheter may require antibiotic prophylaxis prior to dental care. Medical consultation may be warranted.

Renal dialysis patients with shunts for hemodialysis require antibiotic prophylaxis prior to invasive dental care.

Considerations in the Use of Antibiotics Preferred use of narrow spectrum antibiotics (e.g.,

Metronidazole) to minimize development of antibiotic resistance

Possibility of presence of antibiotic resistant strains Culture and antibiotic sensitivity may be indicated

Use of antibiotics may lead to overgrowth of Candida albicans Antifungal treatment may be indicated in conjunction

with systemic antibiotics Local delivery antibiotics may be useful but have

not been evaluated

Factors that Predispose to Oral Lesions

CD4+ counts < 200cells/mm3

Viral load > 3000copies/mm3

Xerostomia Poor oral hygiene Smoking

HIV RISK FACTORS for NATIVES

Lack of knowledge of HIV/STI’s High STD/STI rates High rates of substance abuse High rates of emotional problems Low SES

SUBSTANCE ABUSEHighest rate of illicit drug use among ethnicities - 12.8%Second-highest rate of methamphetamine useAlcohol paradox –

highest rate of alcohol mortality = 638% US all races rate

highest rate of non-drinkers

SEXUALLY TRANSMITTED INFECTIONS

2nd highest rate of all ethnic groupsGonorrheaChlamydia

3rd highest rate of syphilis

HPV – Human Papillomavirus

Cause of most or all cancer of the cervix – which is one of the preventable cancers

AI/AN cervical cancer rates among highestDecreasing due to increased Pap smear screeningGardisil HPV vaccine now available

HEPATITIS

Hepatitis B – 2nd highest rate among ethnic groups

Hepatitis C – the highest rate of new cases among ethnic groups

Lack of HIV/STI Knowledge

Personal observation in the fieldAge-independentGender-independentUrban-rural independent

Add: “It won’t happen to me.”

LACK OF STD/STI KNOWLEDGE

Also related to…Level of education – low high school diploma rate

66% of Natives compared to 75% US average

Income level - 24.3% Natives living at poverty level

(2002-2004)

HIGH RATES of EMOTIONAL PROBLEMS

PTSD rates 8% US All Races 22% AI/AN 45-57% AI/AN Viet Nam vets

WAITING FOR THE AX TO FALL

WHAT DO WE NEED?

WE NEED AN ACCURATE, UP-TO-DATE, CONFIDENTIAL SURVEILLANCE SYSTEM!

WHAT DO WE NEED TO KNOW? We need to know new infection rates

We need to identify the most at-risk groups: Geographic areas? IDUsers? Sexually-active youth?

We need to know where to focus our meager resources Geographic areas? IDUsers? Sexually-active youth?

THEN WE NEED TO…

TEST, TEST, TEST! EDUCATE, EDUCATE, EDUCATE! IDENTIFY BEST PRACTICES FOR CREATING
