Genetics and Altered Immune

Responses







Susan Wise, RNC, PhD

Basic Principles of Genetics

 Genes – arranged in a specific formation

along the chromosomes. There are

dominant and recessive traits that are

inherited by offspring.

 Chromosomes – 22 pair plus sex

chromosomes. Females have two X

chromosomes and males have one X and

one Y.

 DNA – stores genetic information on double

strands.

 RNA – stores genetic information on single

strands.

 B lymphocyte differentiates into plasma cells

 Mature plasma cells secrete immunoglobulins

(antibodies)

 Memory cells remain

 Successive exposures trigger memory cells to

rapidly produce antibodies

to maintain self-tolerance

 Type I – anaphylaxis, allergic rhinitis,

asthma

 Type II – cytotoxic (transfusion reaction)

loss of mobility due to

pain/joint destruction.

 systemic disease

 blood vessels

 heart

 lungs

 muscles

 A family of chronic diseases of joints.

 can occur in children and adults.

 inclosing spondylitis

 Reiter's syndrome (reactive arthritis)

 psoriatic arthritis

 joint problems associated with inflammatory bowel disease

(enteropathic arthritis)

 All of them:

 sacroiliac joint

 Affect areas around the joint where your ligaments and

tendons attach to bone such as at the knee, foot, or hip.

 Spondyloarthropathies are different from rheumatoid

arthritis (RA) in adults and juvenile rheumatoid arthritis

(JRA) in children

Lyme Disease

 Borrelia burgdorferi

 Bite of infected blacklegged ticks

 Symptoms

 Fever

 Headache

 Fatigue

 Characteristic skin rash called erythema migrans

 If left untreated, infection can spread to joints, the

heart, and the nervous system

 Most cases of Lyme disease can be treated

successfully with a few weeks of antibiotics

 Steps to prevent Lyme disease include using insect

repellent, removing ticks promptly, landscaping, and

integrated pest management.

Gout

 also called metabolic arthritis

 congenital disorder of uric acid

metabolism

 monosodium urate or uric acid

crystals are deposited on the

articular cartilage of joints, tendons

and surrounding tissues due to

elevated concentrations of uric acid

in the blood stream

Gout

Systemic Lupus Erythematosus

 body's natural defense system attacks its own tissues

 This causes inflammation

 Inflammation causes swelling, pain, and tissue

damage throughout the body

 Kidneys

 Heart

 Lungs

 nervous system

 blood cells

 Although some people with lupus have only mild

symptoms, the disease is lifelong and can become

severe.

(endothelial cells)

 Excessive activation of the dermal

connective tissue cells, the fibroblasts

 Fibroblasts normally produce collagen and

other glycosamine proteins

Organ Transplantation



 Allograft - tx from same species

 Autograft – tx from self

and heart. Heart to someone else.

Major Organs and Tissues

Transplanted



 Thoracic organs

 Other organs

 Tissues

 Cells

 Fluids

Acute Tissue Rejection

 Most common and treatable

 Recipient’s T lymphocytes attack organ

 Occurs days to months after transplant

 Prevent - use of antimetabolites or anti-inflammatory

medications prior to surgery

 Treat with immunosuppressants and steroids

 Elevated BUN, creatinine, liver enzymes, bilirubin, and

cardiac enzymes.

 Fever, redness, swelling, and tenderness over graft site.

Chronic Rejection



 Antibody-mediated response

 Occurs months to years post transplant

 Resembles chronic inflammation and scarring. Tissue is

fibrotic and scar-like tissue.

 Organ in not able to perform function.

 Antibodies and complement are deposited in the

transplant vessel walls, causing narrowing and decreased

organ function. Scaring caused by chronic ischemia from

blood vessel injury.

 Changes are permanent and irreversible.

 Back on the transplant list.

Graft-versus-host disease (GVHD)

 Fatal complication; not a close match.

 Blood transfusion. Bone marrow transplant

 Occurs within the first 100 days of transplant.

 T cells in graft recognize host as foreign and attack.

 Affects skin, liver, and GI. A pruritic rash begins on

hands and feet, and it may

spread, abdominal pain,

nausea, bloody diarrhea.

More organs involved, poorer

prognosis.

No adequate treatment

Immunosuppressive Therapy

(Sandimmune, Neoral, Gengraf) and

tacrolimus (Prograf)

 Corticosteroids – prednisone,

methlprednisolone (Solu-Medrol)

 Mycophenolate mofetil (CellCept)

 Sirolimus (Rapamune)



 Often used in combinations

Altered Protection

output

Clinical Management of HIV

Disease in Adults

 First recognized 25 years ago.

 First decade - prevention and treatment of the

infectious complications.

 Second decade - effective antiretroviral therapies.

 “Lazarus effect” - 1996 - highly active antiretroviral

therapy (HAART).

 1997 the incidence of many opportunistic diseases

declined dramatically

 During the last several years in this decade, new

drugs with less adverse effects and in more

convenient dosing schedules

25,000,000



More than 25

million

people have

died of AIDS

since 1981.



Africa has 12

million AIDS

orphans

HIV/AIDS is

100%

preventable

Still Many Underserved

 Opportunistic infections and progression to AIDS is still

occurring among key members of our global society,

namely

 Undiagnosed or untreated

 Disenfranchised or marginalized

 Under-treated

 Unempowered (e.g., women)

 Impaired (e.g., psychiatric or addicted members of society)

 Nonadherent patients

 Patients in third-world countries who do not have access to

HAART

 Patients not under the care of an HIV-specialist or experienced

HIV provider

 Patients who are just starting treatment

 People for whom antiretroviral therapy has failed

HAART - Highly Active

Anti-Retroviral Therapy

 Rapid, significant improvement in immune function in HIV-

infected patients

 Patient’s lives have been extended substantially

 Dramatic reductions in the incidence of many opportunistic

diseases

 Pneumocystis jiroveci pneumonia (PCP)

 cytomegalovirus retinitis

 mycobacterium avium complex

 cytomegalovirus infection

 cryptosporidiosis

Primary HIV

Infection/Seroconversion

• Two to six weeks after an exposure to HIV, a newly infected person

will develop a high level of viral load (measured by HIV/RNA plasma

levels)

• About 50% to 90% of these people will manifest as “mononucleosis-

like.”

• “Seroconversion” illness”

• Primary infection manifests in a variety of ways

•Mild fever, myalgia

•Arthralgia, lymphadenopathy

•Anorexia, pharyngitis

•Weight loss

•Rash

•Meningitis

Patients are Partners in Care

Patients need to be considered full partners

in care.

Patients must be fully apprised of the risks

and benefits as well as their

responsibilities

Issues of drug toxicity, pill burden, dosing

time constraints, drug-nutrient

interactions, and the unwavering

commitment to adhere to complex

medication schedules

Goals of Therapy

 Prolongation of life and improved quality of life.

 The greatest possible reduction in viral load

 Immune system reconstitution that is quantitative and

qualitative

 Rational sequencing of drugs that achieve virologic goals

but also:

 Maintains therapeutic options

 Relatively free of adverse effects

 Realistic with regard to probability of

adherence.

 The epidemiologic goal is the reduction of HIV

transmission

Adverse Effects of Treatment



 Dyslipidemia and Lipodystrophy

 A syndrome consisting of altered fat

distribution within the body and

metabolic abnormalities, such as

hyperlipidemia

 First described in 1998

Fat Redistribution

 Changes in the placement of visceral

fat to the

 Trunk (truncal obesity)

 Neck (buffalo hump)

 Especially in women, the breasts

 Subcutaneous fat is lost in the

 Face (e.g., “facial wasting”)

 Extremities

 The buttocks

Nurses - HIV

 CDC has documented 32 cases of

occupationally transmitted HIV in health

care workers, including 12 nurses. And

investigated another 69 cases, including

14 nurses.

 These are reported cases. Many

exposures go unreported for fear of

discrimination or loss of confidentiality.

Nurses - Hepatitis B



 HBV. . . is more readily transmitted: 8,700

health care workers each year contract

hepatitis-B on the job; more than 200 die.

 A safe and effective vaccine is now available;

many employers must provide it for free

 If you are not yet vaccinated, don't wait. Begin

the series of three shots now, so you can begin

building immunity to this deadly disease

Nurses – Hepatitis C



 HCV. . . is a growing threat to nurses.

Infection with HCV appears to carry a

great potential for chronic liver disease.

 Antibody tests have been developed to

detect the virus, but the number of

health care workers infected is not

known.

 No vaccine is currently available.
