PRACTICE QUESTIONS Flashcards
A 20 year old male heart transplant recipient is 2 days post transplant who is currently receiving daily ATG at 1 gram/kg and is 60 kg. His labs came back today with WBC at 5.0, platelets at 70, 0.1% lymphocytes and a HCT of 24 on his CBC. What are your initial next steps?
- Continue his daily ATG, contact transplant MD regarding HCT of 24
- Hold daily ATG, draw CBC in am, reassess CBC, contact MD regarding HCT of 24
- Give ½ dose of ATG, contact transplant MD regarding HCT of 24
- Continue daily ATG, repeat CBC in 12 hours
- ATG should be held. Platelets are too low, additional ATG will lower platelets even further, HCT already low, could be bleeding, need to look for possible source of bleeding, patient only has 1% of lymphocytes, so patient is covered at the moment for immunosuppression, also receiving steroids and mycophenolate .
A 20 year old female lung transplant recipient who is 6 months post transplant came in for routine clinic follow-up. Her immunosuppression regimen consists of
tacrolimus/mycophenolate/steroids. You are counseling her on tacrolimus side effects. You would include which of the following:
A. Hypomagmesium, hyperkalemia, hyperlipidemia
B. Hypomagnesium, hypokalemia, hyperlipidemia
C. Hypermagnesium, hyperkalemia, hypolipidemia
D. Hypermagnesium, hyperkalemia, hypolipidemia
A- tacrolimus will lower your magnesium, increase your potassium and increase your lipids
A 21 year old female kidney recipient 10 years post transplant was seen in your post transplant clinic. She has been on cyclosporine for the past 10 years. After reviewing her history and reviewing laboratory studies you note she has a creatinine 1.2 and a cyclosporine level of 250. She also has worsening gingival hyperplasia. You have a long discussion about options. Your next initial step will be to:
- Switch from cyclosporine to a non CNI as this is causing ongoing renal injury
- Start referral and evaluation for kidney re-transplant due to rise in creatinine
- Lower cyclosporine dose and repeat laboratory studies within the week
- Referral to oral surgeon for gingival hyperplasia
3- First will be to lower cyclosporine dose and repeat level and creatinine within the week. Normal levels at 10 years post transplant would be between 100-150 at most (would run lower with rising creatinine). A referral is warranted for the gingival hyperplasia which may need surgical intervention for appropriate hygiene (is not your initial step). You do not need to eval for re-transplant.
A 25 year old liver transplant recipient who is 10 years post transplant came in for routine labs. His immunosuppression regimen consists of tacrolimus/mycophenolate. A tacrolimus level was drawn. The patients calls to tell you he was placed on clarithromycin 4 weeks ago as he was diagnosed with lymes disease. Based on this information, you can expect his tacrolimus level to results to be:
A. Therapeutic between 15-20
B. Supratherapeutic over 20
C. Therapeutic between 5-10
D. Undetectable, less than <2.5
B- Clarithomycin will increase tacrolimus levels, dose will need to be adjusted and repeat levels, remember, all “mycins”, erythromycin clarithromycin, azithromycin- Zpak.
A 30 year old heart transplant was seen in your post transplant clinic. He has been on sirolimus for the past 3 years due to coronary artery disease. You are doing his annual laboratory studies which will include a urine analysis (UA). Your initial reason for screening is due to:
- Sirolimus can cause hematuria in your urine
- Monitoring for UTI bacteria in urine is required
- Sirolimus can cause protienurinia
- Monitoring for yearly viral studies in urine is necessary
3- sirolimus is associated with proteinuria. Patient may need to have dose lowered or taken off of sirolimus if noted to have high levels of protein in the urine.
A 30 year old male kidney transplant recipient is on tacrolimus, mycophenolate and prednisone 9 months post transplant. You are seeing him in clinic for his routine appointment. He has complaints of diarrhea and vomiting and a 5 pound weight loss. You have ruled out rejection and bacterial/viral cause for his symptoms. You are reviewing his medication list. Based on his immunosuppression medications, which is most likely causing the symptoms:
- Prednisone
- Tacrolimus
- Mycophenolate
- Sirolimus
- Mycophenolate has known side effects of nausea, vomiting and diarrhea and possible weight loss.
Based on the symptoms, you switched the 30 year old male kidney transplant recipient immunosuppression regimen. You took him off the tacrolimus, mycophenolate and prednisone due to the complaints of diarrhea and vomiting and a 5 pound weight loss. Since you believe the mycophenolate was the cause of the symptoms, what is the initial regimen you would switch to?
- Tacrolimus/Azathioprine/Prednisone
- Tacrolimus/Sirolimus/Prednisone
- Tacrolimus/Myfortic/Prednisone
- Cyclosporin/Myfortic/Prednisone
- Tacrolimus, myfortic and prednisone- you would first change to the enteric coated mycophenolate. It was developed to reduce the upper GI effects of mycophenolate. Unlike mycophenolate which releases in
the stomach, myfortic is released in the small intestine. You can still have some constipation and nausea with myfortic when released in the small intestines.
A 30 year old male kidney transplant recipient who is 5 years post transplant clinically stable outpatient has new rejection. The pathologist calls you with the results. He states the biopsy is characterized by vascular inflammation and damage. There is endothelial activation with intravascular macrophages and capillary destruction. There is complement and HLA deposition. Based on what you know about cellular and antibody rejection, you know the diagnosis and next steps will be:
- Cellular rejection and treat, admit with IV high dose steroids
- Antibody mediated rejection and treat with IVIG or Rituximab
- Cellular rejection and treat with oral high dose steroids
- Antibody mediated rejection and treat with bortezomib
- Description is for AMR, 1st line treatment is IVIG and Rituximab, may use pheresis 1st, bortezomib is not 1st line therapy
Immunosuppressive agents can include antibodies. An example of a polyclonal antibody used in solid organ transplantation to control allograft rejection is:\
- Alemtuzemab
- Rapamycin
- Tacrolimus
- Anti-thymocyte globulin
