CYSTIC FIBROSIS Essay Research Paper CYSTIC FIBROSISONE

CYSTIC FIBROSIS Essay, Research PaperCYSTIC FIBROSISONE OUT OF EVERY 2,500 BIRTHS IN THE UNITED STATES WILL BE DIAGNOSEDWITH CYSTIC FIBROSIS. THIS FACT MAKES CYSTIC FIBROSIS ONE OF THE MOST COMMONGENETIC DISEASES IN THE NATION. ABOUT 30,000 Americans HAVE THE DISEASE, BUTEven THOUGH CYSTIC FIBROSIS IS THE NATIONS MOST COMMON GENETIC DISEASE THEMAJORITY OF AMERICANS KNOW LITTLE ABOUT IT.

CYSTIC FIBROSIS IS RELATIVELYCOMMON IN CALCASTION PEOPLE BUT RARE IN AFRICAN-AMERICAN. THE DISEASE IS VERYUNCOMMON IN MONGOLIANS. FIVE PERCENT OF THE POPULATION IN THE UNITED STATES ARECarriers OF THE GENETIC DISEASE.

CYSTIC FIBROSIS, SOMETIMES CLASSIFIED AS MUCOVISCIDOSIS, IS A DisorderIN WHICH THE EXCRORINE GLANDS SECRETE ABNORMALLY THICK MUCUS. THIS LEADS TO THEObstruction OF THE PANCREAS AND CHRONIC INFECTIONS OF THE LUNGS, WHICH GENERALLYCAUSES DEATH IN CHILDHOOD OR EARLY ADULTHOOD. SOME MILDLY AFFECTED PATIENTS MAYSURVIVE LONGER. PATIENTS WITH PANCREATIC INSUFFICIENCY TAKE PANCREATIC ENZYMESWITH MEALS. THOSE WITH RESPIRATORY INFECTIONS ARE TREATED WITH ANTIBIOTICS,MOSTLY WITH AEROSOLS THAT RELIEVE CONSTRICTION OF THE AIRWAYS. PHYSICAL THERAPYIS USED TO HELP PATIENTS COUGH UP THE OBSTRUCTING MUCUS.

INTESTINAL OBSTRUCTION,WHICH OCCURS MOSTLY IN INFANCY, MAY REQUIRE SURGERY.Inch 1989, RESEARCHERS FOND THE ABNORMAL GENE THAT CAUSES CYSTIC FIBROSIS.THIS GENE IS LOCATED ON CHROMOSOME 7. A Person WHO HAS TWO CYSTIC FIBROSISGENES HAS THE DISEASE. A PERSON THAT CARRIES ONE OF THE GENES DOES NOT Have THEGENETIC DISEASE, BUT IS A CARRIER.THE SYMPTOMS OF CYSTIC FIBROSIS SOMETIMES OCCUR IMMEDIATELY AFTER BIRTH.MUCUS SECRETIONS MAY APPEAR IN THE BABY? S INTESTINES, WHICH CAN CAUSEObstruction IN THE INTESTINES.

IN ALL CASES, THE CHILD WILL GAIN LITTLE WEIGHTRight FROM BIRTH, BECAUSE THE PANCREAS IS NOT PRODUCING ENZYMES. LITTLE TO NOFoods ARE ABSORBED IN THE CHILD? S SYSTEM. A Child WITH CYSTIC FIBROSIS MAYHAVE REOCCURRING RESPIRATORY INFECTIONS, ALONG WITH COUGH AND FEVER. THIS MAY BeMORE Severe AND PERSISTENT THAT NORMAL THIS IS A RESULT OF THE THICK, STICKYMUCUS THAT WILL Keep AND TRAP GERMS IN THE BRONCHIAL TUBES. IT SHOULD BE TAKENIN TO CONSIDERATION THAT CHILDREN WITH CYSTIC FIBROSIS HAVE LARGE APPETITES ANDEat A GREAT DEAL. IN SPITE OF THEIR MALNUTRITION, THEY ART NOT IN PAIN AND DONOT GENERALLY FEEL IT.

Infusion OF ANIMAL PANCREAS, IN POWDER OR GRANULE FORM, ARE PRESCRIBEDTO REPLACE THE MISSING ENZYMES FROM THE PANCREAS, AND THE AMOUNT OF FAT ISDECREASED IN THE CHILD? S DIET. WITH THIS TREATMENT THE CHILD BEGINS TO GAINWEIGHT. TO KEEP THE LUNGS FREE OF AS MUCH MUCUS AS POSSIBLE, THE PATIENTS MAYNeed TO HAVE DAILY RESPIRATORY PHYSICAL THERAPY. ANY RESPIRATORY INFECTION THATARISE ARE TREATED WITH LARGE AMOUNTS OF ANTIBIOTICS.CYSTIC FIBROSIS CAN NOT Yet BE CURED.

ALTHOUGH THE IDENTIFICATION OFCHROMOSOME 7 HAS PAVED THE WAY FOR GENE THERAPY. ANTIBIOTICS AND ENZYMES ARE NOTTHE Lone TREATMENTS FOR CYSTIC FIBROSIS. ONE RELATIVELY NEW TREATMENT IS ABIOTECH DRUG THAT THINS THE MUCUS, WHICH HELPS THE LUNGS FUNCTION BETTER ANDReduce THE RISK OF INFECTIONS. GENE THERAPY IS STILL IN EXPERIMENTAL STAGES.
