Glukokortikoid,
muromonab-CD3,
azotiopürin,
takrolismus,

32
Q

selektif T hücre inhibisyonu yapan ilaç hangisidir Siklofosfamid, siklosporin, kortikosteroid, aktinomisin, bleomisin

A

siklosporin

33
Q

Spesifik tedavilere cevap alınamayan Behçet üveiti, psöriazis, atopik dermatit, ve romatoid Artrit tedavisinde kullanılan ve nefrotoksik etkisi olan ilaç aşağıdakilerden hangisidir?

Paramomisin,
metotreksat,
siklofosfamid,
siklosporin,
klorambusil

A

siklosporin

34
Q

cyclosporine and tacrolimus absorption and metabolism made by ?

A

CYP3A4, CYP3A5 and P-glycoprotein (P-gp)

35
Q

calcineurin inhibitor kulanımını engelleyen limit nedir?

A

nephrotoxicity

infections

36
Q

cyclosporine’in yan etkileri nelerdir?

A

Hirsutism, or excessive hair growth,

37
Q

sirolimus and everolimus are metabolized by?

A

CYP3A4

Sirolimus has a longer half-life

38
Q

Which drug used to prevent allograft rejection can cause hyperlipidemia?

A. Basiliximab
B. Belatacept
C. Mycophenolate mofetil
D. Sirolimus

A

Correct answer = D. Patients who are receiving sirolimus can develop elevated cholesterol and triglyceride levels,
which can be controlled by statin therapy. None of the other agents have this adverse effect.

39
Q

Which clinical situation is least appropriate for immunosuppression with sirolimus?

A. A patient with primary renal failure.
B. A patient who has failed calcineurin inhibitors due to neurotoxicity.
C. A patient who is 6 months postliver transplant and the incision site is fully healed.
D. A patient with an abnormal lipid profile.

A

Correct answer = D. A patient with an abnormal lipid profile is a poor candidate for immunosuppression with sirolimus, since this medication is known to cause or exacerbate hyperlipidemia, particularly triglycerides and total cholesterol. A patient with primary renal failure would be a candidate for sirolimus, since it does not cause
nephrotoxicity as calcineurin inhibitors do. It would be appropriate to switch a patient who has failed calcineurin inhibitors due to neurotoxicity to sirolimus for immunosuppression since it is not associated with that adverse effect. Sirolimus is known to impair wound healing, but a patient with a fully healed incision site could
appropriately be placed on sirolimus.

40
Q

mycophenolate neyi engeller?

A

guanosine monophosphate oluşumunu

B-cell proliferation by eliminating de novo production of guanosine monophosphate.

41
Q

Which immunosuppressant medication avoids the need for therapeutic drug monitoring?

A. Cyclosporine
B. Tacrolimus
C. Mycophenolate mofetil
D. Sirolimus

A

Correct answer = C. Calcineurin inhibitors (cyclosporine and tacrolimus) and mTOR inhibitors (sirolimus and everolimus) require therapeutic drug monitoring in order to maximize efficacy (prevent rejection episodes) and minimize toxicity (adverse effects). Mycophenolate mofetil is the correct answer since there is no role for routine monitoring with this medication.

42
Q

using corticosteroids cause?

A

cause hypercholesterolemia
, cataracts,
osteoporosis,
and hypertension with prolonged use
