Hi Suzi :lol:
We are getting a nice collection of "Susie's" here..all with variations of spellings. You are most welcome to our family where many of us have gone through the mis-diagnosis phase (some to the point of being critically ill by the time they were correctly diagnosed).
You are right, Lupus can cause Pericarditis as well as Pulmonary Hypertension. However, there are many different types of rashes with Lupus with almost an equal amount of different causes. Most of the Lupus rashes are sun sensitive and worsen (or appear) after sun exposure. The skin is involved in more than 90% of people with lupus. There is the classic lupus rash which is a redness on the cheeks and over the nose (malar blush) often brought on by sun exposure (aka: Acute Cutaneous Lupus Erythematosus). Then, there is Discoid lupus with the red skin patches on the skin and scaliness that can lead to scarring. This rash usually occurs on the face and scalp and can lead to loss of scalp hair (alopecia).
Then there is Subacute Cutaneous Lupus Erythematosus lesions. This rash usually occurs after sun exposure, the lesions are usually itchy. It may involve any place on the body, and because the lesions may be on the palms of the hands and the soles of feet, they resemble a drug reaction.
Chronic Cutaneous Lupus Erythematosus, referred as Discoid Lupus Erythematosus, usually involves the face, scalp and ears, but it may occur anywhere. This rash may also be itchy and red. The rash may have slightly elevated plaques, that in time become raised and bright red, later on the center becomes depressed, the color fades and becomes atrophic (wasting away).
Lupus Panniculitis, appears as deep nodules. The lesion is situated below the skin in the subcutaneous tissue, and heals with a deep atrophy of the involved area.
Bullous Lupus Erythematosus is characterized by the presence of blisters which contain a clear seurous fluid, and may range from 3 to 40mm in diameter. The rash usually appears in sun exposed areas, and only rarely is associated with burning sensation, mild pruritus or redness.
There is a relationship between kidney problems and skin rash. Hyperphosphatemia (elevated phosphate in the blood) can occur, most commonly from kidney dysfunction. Phosphate is eliminated from the
body through the kidneys, and if they are not functioning properly,
phosphate will accumulate in the body. Most of the time,
hyperphosphatemia is asymptomatic, however, it can cause various
symptoms including 1) muscle cramps, 2) tetany ( involuntary contraction of muscles), and 3) perioral numbness or tingling (occurring in, or being the tissues around the mouth), 4) bone and joint pain, 5) pruritus (itchy), or 6) skin rashes. Most of the symptoms of hyperphosphatemia (1-4) result from hypocalcemia (elevated levels of phosphate lead to low levels of calcium in the body). Other symptoms (5-6) may exist on their own, or
may be exacerbated by other compounds that are not eliminated from the
body due to kidney dysfunction.
I hope that this information has been helpful to you. Please let us know if you need anything further.
Peace and Blessings
