Medical Complications Of Kidney Transplantation

However, an important position within the genesis of post-transplant neurologic issues is played by immunosuppressive remedy, which can cause direct neurotoxicity or could favor the development of tumors and opportunistic infection. Since the introduction of new immunosuppressive protocols, the character of post-transplant neurologic problems has modified up to now few years . The prognosis of some neurologic complications in renal transplant recipients has improved considerably, because of development in diagnostic and therapeutic measures. Merkel-cell carcinoma Merkel-cell carcinoma is an unusual tumor, most commonly affecting aged Caucasians. Usually the tumor manifests as a solitary painless erythematous nodule, typically ulcerated, positioned on the top or neck.

In amyloidosis secondary to rheumatoid arthritis, the danger of recurrence is correlated with the exercise of the underlying major disease (Figure 7.17). Good results have been reported in patients with familial Mediterranean fever (Sever et al., 2001). Recurrence is possible, however the early administration of colchicine, 1 mg/day indefinitely, can prevent the deposit of amyloid substance on the transplanted kidney.

Identification of the offending organism could additionally be obtained by blood culture or by deep bone aspiration/biopsy. Waiting for identification of the microorganism, the intravenous administration of broad-spectrum antibiotics over 4–6 hours is really helpful. Bone ache Patients treated with calcineurin inhibitors may undergo from a painful leg syndrome characterized by pain over the long bones, localized to the knees and ankles, without joint inflammation. The pain is mostly symmetrical, may interfere with strolling, just isn't relieved by relaxation, and should wake the patient from sleep.

Gastrointestinal complications are frequent in renal transplant recipients and should involve any tract of the gastrointestinal tube (Helderman and Goral, 2002; Ponticelli and Passerini, 2005). Most complications are trivial and are often not referred by the patient to the transplant clinician. Nevertheless, even minor gastrointestinal symptoms could impair the psychological general well-being (Strid et al., 2002). In about 10% of renal transplant sufferers, severe gastrointestinal issues might develop, ultimately resulting in graft loss and even affected person dying (Sarkio et al., 2004). The most frequent gastrointestinal problems in renal transplant recipients include oral lesions, esophagitis, peptic ulcer, diarrhea, colon hemorrhage, or perforation. These disorders may be associated to medicines, infections, and/or exacerbation of pre-existing gastrointestinal pathology.

Herpes simplex virus (HHV-1 and -2) Reactivation of herpes simplex virus infection is widespread in renal transplant recipients. Infection often includes the orolabial region, and fewer commonly the anogenital area.

Kidney transplant recipients who develop donor-specific antibodies or non-HLA antibodies might develop an antibody-mediated form of rejection, additionally referred to as humoral rejection (Figure 4.2). A number of related techniques have been proposed to forestall hyperacute rejection in ABO-incompatible kidney transplants. Graft nephrectomy may be necessary when severe systemic toxicity from necrotic renal tissue and consumption coagulopathy develop. Diabetes Both CsA and TAC can trigger hyperglycemia, by inducing an acquired insulin sensitivity defect . Their diabetogenic impact is strongly enhanced by the concomitant administration of corticosteroids. There is agreement that tacrolimus is extra diabetogenic than cyclosporine (Gourishankar et al., 2004; Martinez-Castelao et al., 2005; Wong et al., 2005), most likely as a end result of it also exerts a direct toxicity on islet cells (Tamura et al., 1995).

Renal carcinoma According to the CTTR, renal carcinomas represent 14% of all tumors . Most renal carcinomas in renal transplant recipients occur within the native kidney, although about 10% of them might contain the transplanted kidney (Moudouni et al., 2005). This elevated prevalence could also be defined by the excessive variety of renal tumors in sufferers with end-stage renal failure. The prognosis for sufferers with renal cancer is carefully related to tumor dimension and extension outdoors Gerota’s fascia. Experimental research confirmed that rapamune could be very efficient in halting the development of renal carcinoma and in inhibiting metastasis (Luan et al., 2003).

Clinical analysis Clinically, CAN is characterized by a slowly progressive increase in serum creatinine, often related to proteinuria and hypertension. Proteinuria generally ranges from 0.four to 2 g/day, but nephrotic proteinuria may be observed within the presence of transplant glomerulopathy (Banfi et al., 2005).
