We reviewed 43 adult kidney transplant patients (32 males and 11 females, 14-68 years of age) performed at our center between July 1999 and February 2002. Donors (39 males and 4 females) comprised two cadaverics, five living-related and 36 living-unrelated; age 18-44 years. Indications for kidney transplantation (KT) were: chronic glomerulonephritis (8), re-transplantation (4) and chronic pyelonephritis (3); kidney disease was unknown in 15 cases. ATG-F was given as a single intra-operative bolus induction therapy in 26 patients; extended ATG-F dose was given in 17 patients because of a high sensitization status, slow graft function (SGF) or development of calcineurin inhibitors toxicity. ATG-F was stopped in seven out of 17 patients because of thrombocytopenia or severe anemia. ATG-F-related fever occurred in six patients. Acute rejection (AR) occurred in eight patients (18%) 5-11 days post-KT. ATG-F was given in three steroid-resistant AR. Infection occurred in 19 patients (44%) for a total of 32 infectious episodes comprising 24 bacterial infections (nine urinary, seven catheter-related and three respiratory), six viral infections (five CMV and one herpes) and two fungal infections (one pulmonary aspergillosis and one catheter-related candidiasis). The hospital stay was 8-75 days for a median of 13 days. The mean serum creatinine upon discharge, at 1 and 6 months after KT were: 2.04+/-0.37, 1.43+/-0.16 and 1.29+/-0.08, respectively. One patient lost his graft on day 9 because of graft microthrombi related to Factor V-Leiden mutation. The 6 months actuarial patient and graft survival were 100 and 97.6%, respectively. ATG-F as a bolus therapy is an effective and safe induction treatment in KT.

Treatment modalities of patients with atopic dermatitis (AD) are dependent on patient age, on the intensity of both skin symptoms and subjective signs of the disease i.e. itch and sleep disturbances, on the body surface involved with lesions, as well as on the type of sensitizing allergens. The characteristic of these allergens is crucial to start prophylaxis and to make decision about specific immunotherapy. In asymptomatic period of the disease the most important factor is to prevent dryness of the skin using emollients, which reconstruct integrity and continuity of stratum corneum. This procedure prevents penetration of air-borne allergens across damaged skin barrier into the skin. In mild AD cases, pimecrolimus (mainly in children) and corticosteroids of the lowest potency alternatively with their basis should be recommended. In moderate intensity AD either topical treatment with calcineurin inhibitors i.e. tacrolimus and pimecrolimus or topical corticosteroids from 4-5 group of American classification should be applied. In addition, PUVA/UVB phototherapy may be beneficial, as well as immunotherapy with specific airborne allergen/s. Coexisting bacterial skin infections should be treated with systemic antibiotics (macrolides, quinolones, and cephalosporins), viral herpes infection systemically using acyclovir for 5-7 days, and fungal infections applying ketoconazole orally, accompanied by topical treatment with miconazole or other antimycotics. Severe AD is an indication for the systemic use of cyclosporin A (rather than corticosteroids), and antibiotics as mentioned above. Prolonged 3-5 year specific immunotherapy is significant concern for selected cases. Sensitive skin areas such as face, orbicular skin, flexures should be treated with pimecrolimus and tacrolimus rather than with corticosteroids, however, topical corticosteroids are recommended on involved skin of the trunk and the extremities besides of flexures. While the improvement of severe AD is reached, the treatment modalities for benign and mild AD should be observed. In all AD patients with active skin lesions antihistaminic drugs of 2nd generation reactive with H1 receptor are a gold standard (or short treatment with these drugs of 1st generation to achieve a sedative effect, followed by the 2nd generation drug), as well as tranquilizers as the combined treatment. There is no reason for the use of anti-leukotriene drugs.

Human papilloma virus (HPV)-associated diseases are increasingly diagnosed in solid organ recipients. Cidofovir (CDV) is a broad-spectrum antiviral agent with activity against all human herpes viruses and HPV. From 2000-2004, a total of 1303 solid organ transplants (SOT) were performed at our center. Six transplant recipients were treated with topical CDV for HPV-associated lesions. One cardiac recipient responded to a single injection of CDV into his recurrent anal condylomata. In a renal recipient with recurrent penile condylomata CDV was injected into the lesions four times (2 week interval) until lesions regressed. One renal recipient developed multiple vaginal and anal intradermal neoplasias, which relapsed after laser ablation. The lesions were repeatedly injected with CDV and completely disappeared. Two renal recipients with widespread verrucae vulgares were treated with CDV gel, which resulted in regression of the lesions. One patient developed donor derived verrucae vulgares on both transplanted hands, which responded to CDV gel. Four of the six patients were switched from calcineurin inhibitors (CNIs) to Sirolimus (SIR). CDV was found effective in the treatment of HPV-associated skin lesions in SOT recipients. It needs to be determined whether switch from CNIs to SIR might have contributed to the beneficial effect of CDV.

Renal transplantation is method of choice for treatment of patients with end-stage renal disease without contraindications for immunosuppressive therapy. Neurological complications occur frequently in renal transplant recipients. They may be the consequence of immunosuppressive treatment, but more often evolve as the consequence of previous disturbances which developed during the state of uraemia and treatment with dialysis. The most pronounced neurotoxic effect has calcineurin inhibitors tacrolimus and cyclosporine. The spectrum of neurological disturbances caused by calcineurin inhibitors range from very mild symptoms as paraesthesiae, tremor, headache or flushing, to severe changes that may cause lethal outcome. Peripheral neuropathies in renal transplant recipients may occur in the form of mononeuropathy or polyneuropathy. Cerebrovascular diseases are consequence of changes on blood vessels caused by uraemia, dialysis and side effects of immunosuppressive drugs. They cause death in 8% of renal transplant recipients. Central nervous system (CNS) infections usually occur during the first posttransplant year. Unclear symptomatology frequently postpones the diagnosis. Diagnostic evaluation should include magnetic resonance imaging for localization of the process, as well as lumbal puncture in cases without contraindications for the procedure, in order to determine the causative agent. Regarding the ominous prognosis of CNS infections in the immunocompromised host, only timely diagnosis may improve survival. The most common causative agents are Cryptococcus neoformans, Listeria monocytogenes and Aspergillus funigatus. Viral infections also occur, and are commonly caused by herpes virideae, varicella-zoster virus and papova virus. CNS infections clinically present as meningitis, progressive dementia or focal neurological defect. The most common primary brain tumors are B-cell lymphomas, but glioblastoma, hemangioblastoma, leiomyosarcoma or glioma may also occur. In cases of neurological posttransplant complications, optimal treatment should be guided by neurologist, nephrologist and infectologist, in some cases also by neurosurgeons.

Human herpes virus (HHV)6-associated limbic encephalitis and/or myelitis is one of the life-threatening central nervous system complications following allogeneic hematopoietic stem cell transplantation (HSCT). Recent reports have shown significant correlations of these complications with unrelated cord blood transplantation (UCBT). We retrospectively analyzed 228 allogeneic HSCT recipients in our single institution; 13 patients (5.7%) were diagnosed with HHV6-associated encephalitis/myelitis. This complication was documented in 8 of 51 UCBT recipients (15.7%) and 5 of 177 recipients (2.8%) transplanted with bone marrow or peripheral blood stem cells, indicating a higher incidence of this complication occurring in UCBT recipients (P = .0005). In addition, HHV6-associated encephalitis/myelitis occurred more frequently in recipients who underwent 2 or more HSCTs (7 of 59 recipients [11.9%]), compared to those who received only 1 HSCT (6 of 169 recipients [3.6%], P = .018). Of note, the incidence of this complication increased to 28.6% (6 of 21 recipients), when the analysis was restricted to a second or more UCBT recipients. All 13 patients presented preengraftment immune response prior to the onset of encephalitis. Two patients manifested typical symptoms at the onset of HHV6-associated encephalitis/myelitis, such as memory dysfunction, disorientation, and consciousness disturbance. However, 4 patients presented only with dysesthesia and pruritus, described as typical manifestations of patients with calcineurin-inhibitor-induced pain syndrome (CIPS), and the remaining 7 showed both symptoms, indicating that CIPS-like symptoms might be manifestations of HHV6-associated myelitis. Thus, physicians should be alert to this rare but often fatal complication, particularly for those who receive 2 or more HSCTs using UCB.
