Abstract
Renal transplant recipients (RTR) have a 50-200-fold higher risk for nonmelanoma-skin cancer (NMSC) causing high rates of morbidity and sometimes mortality. Cohort-studies gave evidence that a sirolimus-based immunosuppression may inhibit skin tumor growth. This single-center, prospective, assessor-blinded, randomized trial investigated if switching to sirolimus treatment inhibits the progression of premalignancies and moreover how many new NMSC occur compared to continuation of the original immunosuppressive therapy. Forty-four RTR (mean age 59.9 years, mean duration of immunosuppression 229.5 months) with skin lesions were randomized to sirolimus or continuation of their original immunosuppression. Blinded dermatological assessment at month 6 and 12 by the same dermatologist evaluated the clinical change compared to baseline. Biopsy was performed in suspected malignancy. Already the 6-month-assessment showed significant superiority of sirolimus-therapy: a stop of progression, even regression of preexisting premalignancies (p < 0.0005). This effect was increased at month 12 (p < 0.0001). Nine patients developed histologically confirmed NMSC: one in the sirolimus group, eight in the control group, p = 0.0176. Sirolimus-based immunosuppression in RTR, even when established many years after transplantation, can delay the development of premalignancies, induce regression of preexisting lesions and decelerate the incidence of new NMSC.

Abstract
OBJECTIVES Mesenchymal-epithelial interactions play a pivotal role in tubular morphogenesis and in maintaining the integrity of the kidney. During renal repair, similar mechanisms may regulate cellular reorganization and differentiation. We have hypothesized that soluble factors from proximal tubular epithelial cells (PTC) induce differentiation of adipose-derived adult mesenchymal stem cells (ASC). This hypothesis has been tested using cultured ASC and PTC. MATERIAL AND METHODS Conditioned medium was prepared from injured PTC and transferred to ASC cultures. ASC proliferation was analysed by a fluorometric and photometric assay. Signal transduction was analysed by phosphorylation of extracellular signal-regulated kinase 1 and 2 (ERK1/ERK2). Grade of ASC differentiation was assessed by morphological analysis and cell expression of characteristic markers. RESULTS Conditioned medium significantly induced proliferation and phosphorylation of ERK1/ERK2 of ASC. After 12 days of incubation, cell morphology changed to an epithelial-like monolayer. Expression of cytokeratin 18 was induced by conditioned medium, while alpha-smooth muscle actin, CD49a and CD90 expression decreased. These alterations strongly indicate onset of the differentiation process to the epithelial lineage. In summary, soluble factors from PTC induce signal transduction and differentiation of ASC. CONCLUSIONS Our study shows that conditioned medium from renal tubular epithelial cells provides a convenient source of inductive signals to initiate differentiation of ASC towards epithelial lineage. We deduce that these interactions may play an important role during renal repair mechanisms.

Abstract
We analyzed characteristics, motivation, and effectiveness of complementary and alternative medicine in a large sample of people with multiple sclerosis. A 53-item survey was mailed to the members of the German Multiple Sclerosis Society, chapter of Baden-Wuerttemberg. Surveys of 1573 patients (48.5 ± 11.7 years, 74% women, duration of illness 18.1 ± 10.5 years) were analyzed. In comparison with conventional medicine, more patients displayed a positive attitude toward complementary and alternative medicine (44% vs 38%, P < 0.05), with 70% reporting lifetime use of at least one method. Among a wide variety of complementary and alternative medicine, diet modification (41%), Omega-3 fatty acids (37%), removal of amalgam fillings (28%), vitamins E (28%), B (36%), and C (28%), homeopathy (26%), and selenium (24%) were cited most frequently. Most respondents (69%) were satisfied with the effects of complementary and alternative medicine. Use of complementary and alternative medicine was associated with religiosity, functional independence, female sex, white-collar job, and higher education ( P < 0.05). Compared with conventional therapies, complementary and alternative medicine rarely showed unwanted side effects (9% vs 59%, P < 0.00001). A total of 52% stated that the initial consultation with their physician lasted less than 15 min. To conclude, main reasons for the use of complementary and alternative medicine include the high rate of side effects and low levels of satisfaction with conventional treatments and brief patients/physicians contacts.

Abstract
BACKGROUND The occurrence of a variety of pathological lesions of the heart and kidneys have been described in patients with ankylosing spondylitis (AS). The frequency of these alterations and whether they are specific for AS has been discussed controversially. - METHODS Outpatients with AS were studied to determine the frequency of cardiac and renal alterations and to assess the associated clinical and demographic factors. - RESULTS A total of 77 patients with AS participated in the study (male 84.4%, mean age 48.3 +/- 1.5 years, mean duration of disease 15.4 +/- 1.2 years). Hypertension was present in 36.4% and diabetes mellitus in 13.0%. Impaired renal function (defined by a decrease in GFR) combined with markers of kidney damage suspective for chronic kidney disease were present in 3 patients (3.9%). Pathologic alterations of the heart were found in 25 patients (37.3%). Echocardiographic abnormalities were present in 20 patients (e.g. aortic and mitral insufficiency). Electrocardiographic abnormalities were present in 12 patients (e.g. atrioventricular, left and right branch block). Patients with cardiac abnormalities were older (54.2 +/- 2.9 vs. 44.9 +/- 1.7 years) and had a longer duration of disease (20.6 +/- 2.1 vs. 13.9 +/- 1.6 years) as compared to non-affected patients. - CONCLUSION In our study, cardiac abnormalities were frequently seen in patients with AS, while renal disease was more rare and might be due to diseases not related to AS in most of patients. In contrast to cardiac involvement, it therefore appears questionable, that chronic kidney disease is part of the extraskeletal manifestations, or at least that AS has a high impact on renal integrity.

Abstract
Polymorphisms of DNA repair genes RAD51 and XRCC3 increase susceptibility to acute myeloid leukemia (AML) in adults, an effect enhanced by deletion of the glutathione-S-transferase M1 (GSTM1) gene. In this study, we genotyped 452 children with de novo AML treated on CCG protocols 2941 and 2961 and compared genotype frequencies with those of normal blood donors, and analyzed the impact of genotype on outcome of therapy. XRCC3 Thr241Met, RAD51 G135C and GSTM1 genotypes did not increase susceptibility to AML when assessed singly. In contrast, when XRCC3 and RAD51 genotypes were examined together a significant increase in susceptibility to AML was seen in children with variant alleles. Analysis of outcome of therapy showed that patients heterozygous for the XRCC3 Thr241Met allele had improved post-induction disease-free survival compared to children homozygous for the major or minor allele, each of whom had similar outcomes. Improved survival was due to reduced relapse in the heterozygous children, and this effect was most marked in children randomized to therapy likely to generate DNA double-strand breaks (etoposide, daunomycin), compared with anti-metabolite (fludarabine, cytarabine) based therapy. In contrast, RAD51 G135C and the GSTM1 deletion polymorphism did not influence outcome of AML therapy in our study population.

Abstract
We determined the cellular location of interleukin-18 (IL-18) and caspase-1 and the purinergic receptor P2X7, two proteins necessary for its activation and secretion. The mRNA and protein of IL-18 were detectable in normal human kidney by means of polymerase chain reaction (PCR), in situ hybridization, and Western blot. Immunohistochemistry located IL-18 to nephron segments containing calbinbin-D28k or aquaporin-2 that suggest location in the distal convoluted and the connecting tubule and to parts of the collecting duct. IL-18 was not detected in the thick ascending limb of Henle. Confocal microscopy showed that IL-18 was expressed in cells negative for calbindin-D28k and for aquaporin-2 but positive for the vacuolar H(+)-ATPase. This demonstrates that the intercalated cells produce IL-18. These segments were also positive for caspase-1 and P2X7 that are essential for IL-18 secretion. Our results show that IL-18 is constitutively expressed by intercalated cells of the late distal convoluted tubule, the connecting tubule, and the collecting duct of the healthy human kidney. Since IL-18 is an early component of the inflammatory cytokine cascade, its location suggests that renal intercalated cells may contribute to immediate immune response of the kidney.

Abstract
HISTORY AND ADMISSION FINDINGS A 45-year-old female presented with somnolence and convulsions after finishing her first ironman triathlon. Besides the neurological symptoms she had a swollen face and swollen ankles. Rales could be heard on pulmonary auscultation. The past medical history was unremarkable. Due to musculoskeletal pain the patient had taken ibuprofen until two days before the race. INVESTIGATIONS The laboratory tests showed severe hyponatremia ( 111 mmol/l ) and hypoosmolalitiy of the serum. The osmolality of the urine was high (314 mosm/kg). Radiological examination revealed pulmonary as well as cerebral edema. TREATMENT AND COURSE On admission the patient was treated with hypertonic saline which increased the serum sodium concentration. Nevertheless she developed respiratory and hemodynamic failure. She had to be intubated, mechanically ventilated and needed catecholamines. After treatment with furosemide recovery occurred. The patient was extubated and was transferred to a hospital near her home without any neurolgical deficits one week after admission. One year later the former patient was again participant of the ironman triathlon. She was advised not to drink excessively and received oral salt supplementation. This time the athlete finished the race with a serum sodium concentration of 141 mmol/l. CONCLUSIONS Ultra-endurance exercise can lead to severe hyponatremia, pulmonary and cerebral edema. This is caused mainly by fluid overload due to excesssive drinking and a release of ADH induced by hypovolemia and stress which impairs the excretion of free water. Hence a moderate fluid intake during and after endurance exercise is very important.

Abstract
We report the case of a 38-year-old Caucasian male who was admitted because of end-stage liver failure due to primary sclerosing cholangitis. Because of the rapidly progressive severe hepatic encephalopathy and development of hepatorenal syndrome type I, the patient was immediately upgraded to a high priority status on the liver transplantation waiting list (T2 status according to Eurotransplant criteria). Intermittent therapy with an extracorporeal liver support system (Prometheus) was initiated in order to bridge the time period until the expected transplantation date. Under therapy with the extracorporeal liver support system, total serum bilirubin decreased significantly from 33 to 15 mg/dL after 8 sessions. Simultaneously the encephalopathy resolved gradually within 3 weeks (10 sessions) from initially grade 3 to grade 1. Extracorporeal detoxification therapy was continued for 51 days (23 sessions) until the patient underwent his successful liver transplantation in good general clinical condition. Prometheus, a new liver support system, seemed to sufficiently replace hepatic detoxification on a long-term basis in this patient with end-stage liver failure in order to bridge the time period until liver transplantation.

Abstract
A 45-year-old man was admitted with fever and elevated pancreas enzymes 6 months after simultaneous pancreas-kidney transplantation (SPKT). Function of the allografts was normal. Bacterial and fungal infections were excluded, while Epstein-Barr virus (EBV)-polymerase chain reaction (PCR) was positive. However, screening for EBV-associated lymphoma was negative. EBV infection did not respond to antiviral therapy. After an 18F-Fluorodeoxyglucose positron emission tomography positive signal and an abnormal computed tomography scan of the pancreas transplant, a biopsy revealed a diffuse large monomorphic B-cell lymphoma, which was confined to the grafted organ. Its origin was assigned to the donor by microsatellite analysis. Reduction of immunosuppression and immunotherapy with rituximab was unsuccessful. After 10 weeks, the patient developed an acute hemolytic uremic syndrome which required explantation of the allografts. Subsequent to the intervention, fever disappeared, EBV DNA became undetectable and lymphoma screening remained negative. In posttransplant lymphoproliferative disorder of donor origin after SPKT, transplantectomy may be a curative therapy.

Abstract
AIMS C-reactive protein (CRP) is a component of the acute-phase reaction to inflammation, severe tissue injury, and infection. Investigations have shown that CRP concentration is highly increased in the urine during acute renal graft dysfunction and, therefore, may affect tubular cell metabolism. Nevertheless, no data about the effects of CRP on human renal tubular epithelial cells are available. METHODS Human renal distal tubular cells (DTC) were isolated immunomagnetically and cultured. Cells were stimulated with affinity chromatography pure native CRP from human ascites (10 - 0.001 microg/ml). Phosphorylation of MAP-K was assessed by Westernblot analysis. Release of RANTES and interleukin-6 was evaluated with an enzyme immunoassay. Cytotoxic effects of CRP were determined by a commercially available Live/Dead assay and MTT assay. Effects on cell proliferation were analyzed by a fluorimetric assay. RESULTS Westernblot analysis clearly showed that CRP activates the MAP-K pathway of DTC. CRP upregulated RANTES expression of DTC in a significant and dose-dependent manner. CRP (10 microg/ml) induced a 12.3-fold upregulation, CRP 1 or 0.1 microg/ml induced a 6.3-/2.8-fold RANTES upregulation, respectively. Interleukin-6 synthesis was not influenced. Cytotoxic, proliferative or apoptotic effects were not observed at the concentrations used. CONCLUSIONS We demonstrated an activating effect of CRP on DTC in vitro. In vivo, this effect of CRP might be part of the immune activation cascade during episodes of renal graft rejection or bacterial infections.

Abstract
The main cause of death for diabetic patients and patients on dialysis is coronary artery disease (CAD). The most common cause of graft loss following simultaneous pancreas and kidney transplantation (SPK) is death with a functioning graft due to CAD. Therefore, careful pretransplantation evaluation of CAD is mandatory. In our series, every patient undergoes a noninvasive cardiac function test like dobutamine stress echocardiography (DSE) or myocardial thallium scintigraphy using adenosine to induce medical stress. Thirty patients were evaluated for SPK: 15 patients with myocardial scintigraphy and 8 with DSE. Seven investigations showed pathological findings and we performed coronary angiograms, none of which showed coronary artery stenosis. Seven primary coronary angiograms were performed: four due to a history of CAD and three as a primary diagnostic. Following SPK one patient died at 21 days after transplantation due to myocardial infarction. He had a history of CAD with angioplasty and stent implantation. Noninvasive cardiac function tests like DSE or myocardial scintigraphy are reliable methods to evaluate CAD in patients with diabetic nephropathy awaiting SPK. In case of a suspicious finding or a history of CAD, a coronary angiogram should be performed to assess the need for revascularization. Following this algorithm we may further reduce the mortality of SPK.
