However, these immunologic barriers are present in several potential recipients with willing organ donors, and patients are left to wait for a deceased donor or undergo pretransplant immunomodulation in an attempt to prevent these antibodies from affecting the allograft. 4 »» abo incompatibility the expanding deceased donor waiting list encouraged some centers to evaluate the use of abo desensitization protocols in order to transplant patients with esrd that had willing but abo-incompatible donors. 4 the desensitization protocol most commonly used in the united states involves reducing abo antibody titers through plasmapheresis with iv immune globulin (ivig). Use of plasma exchange to achieve an abo antibody titer of less than 1:8 to 1:32 has resulted in long-term renal transplant results that are comparable to those of abo-compatible transplants, despite an incidence of acute amr that approaches 10% to 30%. 4 »» hla sensitization evaluation of the presence or absence of alloantibodies and t-cell activities to hla antigens plays a significant role in individualization of immunosuppression. 4 a patient’s degree of sensitization is often reported as the percentage of panel-reactive antibodies (pra), which is an estimate of the likelihood of a positive crossmatch to a pool of potential donors. Advancement in hla antibody screening and identification through flow cytometry or solid-phase multiplex platforms has overcome many of the issues stemming from older methods of pra calculations. Patients are considered to be highly sensitized to hla if they have a pra of greater than or equal to 80%, making them less likely to receive a deceased donor organ. Patients with higher pras and preformed antibodies have poorer long-term allograft survival. Although pra is a sensitive test and has predictive value, lymphocytes directly obtained from the donor is a superior method of immune monitoring. The assay is aimed to detect the presence of antibodies directed against the hla antigens of the donor. In this setting, the presence of donor-specific antibodies (dsa) is identified. In one study, allograft survival was significantly lower in patients with dsa. 5 thus detecting dsa and the presence of high pra may indicate the need to enhance immunosuppression to improve posttransplant outcomes and allograft survival. 4 like abo incompatibilities, it is possible to desensitize patients against a willing donor despite the presence of dsa or those awaiting a deceased donor transplant with a broad array of preformed anti-hla antibodies (pra greater than or equal to 30%). 4 there are two general protocols used for hla desensitization. High-dose ivig and low-dose ivig with plasmapheresis. Despite the relatively high degree of amr seen in desensitized patients, this population of patients has acceptable short-term patient and allograft survival. Unfortunately, the long-term results for graft and patient outcomes using either of these two protocols are unknown. 4 treatment desired outcome the major focus of pharmacotherapy in transplantation is to achieve long-term patient and allograft survival. 1,3,5,6 short-term outcomes (eg, acute rejection rates, 1-year graft survival) have improved significantly since the first successful transplant due to an improved understanding of the immune system and enhancements in surgical techniques, organ procurement, immunosuppression, and posttransplant care. Despite the success in improving short-term outcomes, the frequency of graft loss remains higher than desired. 1,3,5,6 it is imperative that transplant practitioners be aware of the specific advantages and disadvantages of the available immunosuppressants, as well as their adverse reactions and drug–drug interaction (ddi) profiles. There are generally three stages of medical immunosuppression. (a) induction therapy, (b) maintenance therapy, and (c) treatment of rejection. Overall, the immunosuppressive regimens utilize multiple medications working on different targets of the immune system. Please refer to table 55–2 for a list of all available immunosuppressive agents. 1,5,6 immunosuppressive therapies—induction therapy the goal of induction therapy is to provide a high level of immunosuppression in the early posttransplant period, when the risk of acute rejection is highest. 5 this stage of immunosuppression is initiated intraoperatively and is concluded within the first 1 to 10 days after transplantation. Antibody induction therapy is not a mandatory stage of recipient immunosuppression and is typically predicated on immunologic risk. However, since acute rejection is a major concern in solid organ transplant recipients and its impact on chronic rejection is undeniable, induction therapy is often considered essential in some organs to optimize outcomes.

Loss o balance and coordination in the setting o vestibular system dys unction or its connections. Patients with chronic bilateral loss o vestibular unction report a sense o unsteadiness, dizziness, vertigo, post-movement gaze variability, and oscillopsia. What is the role of history and examination in the diagnosis of cerebellar ataxia?. From the history, we may elicit the common symptoms o cerebellar ataxia. T e key eatures in disorders presenting with cerebellar ataxia are the presence o poor balance with alls, imprecise hand coordination, postural or kinetic tremors o the extremities or trunk, dysarthria, dysphagia, vertigo, and diplopia. What is ataxia?. 1 ataxia is de ned as a syndrome characterized by lack o coordination o movements and posture secondary to a variety o reasons. 1. Sensory ataxia. Proprioceptive loss causes the brain to be unaware o the position o limbs and trunk. T us, there is incoordination o movements because o incomplete eedback. For example, the major mechanism by which we are able to maintain our balance while walking on uneven ground comes rom the proprioceptive eedback rom muscles and tendons around the ankle. Loss o ankle proprioception results in problems with balance. 2. Optic ataxia. Caused by damage to the parietal lobes, it is characterized by a dys unction o reaching movements under visual guidance (see chapter on dementias). 3. Cerebellar ataxia. T e cerebellum is involved in coordination o movement o di erent muscle groups.
