  • My personal experience with research paper writing services was highly positive. I sent a request to ⇒ www.HelpWriting.net ⇐ and found a writer within a few minutes. Because I had to move house and I literally didn’t have any time to sit on a computer for many hours every evening. Thankfully, the writer I chose followed my instructions to the letter. I know we can all write essays ourselves. For those in the same situation I was in, I recommend ⇒ www.HelpWriting.net ⇐.

  3. 3. Lupus is not… • HIV/AIDS • Leukemia • Cancer • Contagious • Your fault • All in your head 3
  4. 4. Warning Signs of LupusWhen lupus first sets in, symptoms such as fatigue and pain are often non-specific.They can be signs of so many other health problems, which can make diagnosishard. The most common complaint people have is fatigue that is so severe it stopsthem from being able to function normally. This fatigue is often related tofibromyalgia. Fever, muscle and joint pain are also quite common.Muscle & Joint Pain95% of people with lupus experience muscle and joint pain.Fever Greater Than 100° F90% of people with lupus get a fever of more than 100 degrees Fahrenheit (38degrees Celsius).Prolonged or Extreme Fatigue81% of people with lupus suffer from prolonged or extreme fatigue.Anemia71% of people with lupus simultaneously suffer from anemia.
  5. 5. Kidney Problems50% of people with lupus find that their kidneys are affected. Symptoms includeweight gain, swollen ankles, high blood pressure, and decreased kidney function.Pain in the Chest45% of people with lupus experience a pain in their chest upon breathing deeply.This condition is called pleurisy.Rashes80% of people with lupus observe rashes on their skin. A butterfly-shaped rashacross the cheeks and nose is especially common (42%).Light Sensitivity30% of people with lupus become sensitive to light, a condition calledphotosensitivity.Hair Loss27% of people with lupus experience hair loss resulting in patchy or bald spots.
  6. 6. Abnormal Blood Clotting20% of people with lupus report abnormal blood clotting problems.Eye Disease20% of people with lupus concurrently suffer from eye complications such asdry eyes, eye inflammation, and eyelid rashes.Seizures15% of people with lupus experience seizures.Mouth or Nose Ulcers12% of people with lupus report ulcers on their nose or mouth.

  11. 11. Immune system vs. Blood Cells Antibodies attach to blood cellsRed blood cells White blood cells Platelets•Damage to cells •Damage to cells •Damage to cells•Accelerated spleen clearance •Can’t replace fast enough •Can’t replace fast enough•Can’t replace fast enough Anemia Leukopenia Thrombocytopenic anemia Fatigue Difficulty fighting infection Clotting difficulties Bleeding into skin & organs Treatment goal-reduce these antibodies in blood Aladjem (1988) 11
  12. 12. Immune system vs. cell debris Normal breakdown of cells Cell debris in blood stream Antibodies + debris=immune complexesDefective clearance of immune complexes Immune complex + serum proteinsMistakenly deposit in organs other than spleen Activation of complement systemInflammation in organ Complement attracts white cells to site White cells try to eat complex White cells release enzymes Enzymes cause inflammation & tissue damage Repeated attacks of inflammation, healing and scarring can result in more severe organ impairment Aladjem (1988) 12
