Evaluation of rejection, infection, and malignancy outcomes in elderly liver transplant recipients receiving a similar level of immunosuppression compared to a younger group.

Elderly liver transplant (LTx) recipients at a lower risk of acute rejection compared to younger recipients due to immunosenescence. As such, they may benefit from reduced immunosuppression (IS) to minimize infectious and malignant complications. We aimed to evaluate outcomes in LTx recipients ≥60 years compared to a younger group of LTx recipients aged 18-59 years maintained on a similar level of IS. This was a single-center retrospective evaluation of adult LTx recipients from 2013 to 2018 who received methylprednisolone induction and were maintained on tacrolimus, mycophenolate mofetil (MMF), and a prednisone taper. A total of 143 LTx recipients were evaluated. Mean age in the older group was 65 ± 3.8 compared to 49 ± 10.4 years in the younger group (p < 0.0001). Mean tacrolimus levels and the duration of MMF and steroids were comparable. Both groups had a similar incidence of first rejection within 1 year (19.2% in the elderly group vs. 23.1% in the younger group, p = 0.57). There were no statistical difference in terms of infection, malignancy, or patient survival. In conclusion, our data suggests that elderly LTx recipients, when treated with a similar level of IS, had similar 1 year incidence of rejection, infection, malignancy, and patient survival as younger LTx recipients.

Management of hyperkalemia: A focus on kidney transplant recipients.

Hyperkalemia is a frequent complication among kidney transplant recipients that can lead to fatal arrhythmias. The causes of hyperkalemia post kidney transplant are multifactorial and often are drug-induced, and include decreased glomerular filtration rate, tubular dysfunction, and impaired sodium delivery in the distal nephron. This review will discuss pathophysiology and recent updates in the management of both acute and chronic hyperkalemia with a focus on kidney transplant recipients.

Corticosteroids.

Corticosteroids are commonly prescribed for a variety of indications due to the wide range of effects on the human body. Although they exhibit many therapeutic uses, corticosteroids are unfortunately known for their many dose- and duration-dependent toxicities. The purpose of this review is to explore indications for corticosteroid use, differences among formulations, and adverse effects and their management.
