ABO-incompatible kidney transplantation in perspective of deceased donor transplantation and induction strategies: a propensity-matched analysis.

Kidney transplant candidates are blood group incompatible with roughly one out of three potential living donors. We compared outcomes after ABO-incompatible (ABOi) kidney transplantation with matched ABO-compatible (ABOc) living and deceased donor transplantation and analyzed different induction regimens. We performed a retrospective study with propensity matching and compared patient and death-censored graft survival after ABOi versus ABOc living donor and deceased donor kidney transplantation in a nationwide registry from 2006 till 2019. 296 ABOi were compared with 1184 center and propensity-matched ABOc living donor and 1184 deceased donor recipients (matching: recipient age, sex, blood group, and PRA). Patient survival was better compared with deceased donor [hazard ratio (HR) for death of HR 0.69 (0.49-0.96)] and non-significantly different from ABOc living donor recipients [HR 1.28 (0.90-1.81)]. Rate of graft failure was higher compared with ABOc living donor transplantation [HR 2.63 (1.72-4.01)]. Rejection occurred in 47% of 140 rituximab versus 22% of 50 rituximab/basiliximab, and 4% of 92 alemtuzumab-treated recipients (P < 0.001). ABOi kidney transplantation is superior to deceased donor transplantation. Rejection rate and graft failure are higher compared with matched ABOc living donor transplantation, underscoring the need for further studies into risk stratification and induction therapy [NTR7587, www.trialregister.nl].

Discussing Sexual Dysfunction with Chronic Kidney Disease Patients: Practice Patterns in the Office of the Nephrologist.

INTRODUCTION: Sexual dysfunction (SD) is a common problem in patients suffering from chronic kidney disease (CKD). Sexual health remains a difficult subject to detect and discuss. Although many studies have been performed on the incidence of SD, little is known about practice patterns when it concerns quality of life (QoL)-related questions such as SD in the nephrologists' practice. AIM: The aim of this study was to determine to which extent nephrologists, important renal care providers, discuss SD with their patients and their possible barriers toward discussing this subject. METHODS: A 50-item questionnaire was sent to all Dutch nephrologists (n = 312). MAIN OUTCOME MEASURES: The survey results. RESULTS: The response rate of the survey was 34.5%. Almost all responders (96.4%) stated to address SD in less than half of their new patients. The most important barrier not to discuss SD was patients not expressing their concern regarding SD spontaneously (70.8%). Other important barriers were: "the lack of a suitable moment to discuss" (61.9%) and "insufficient time" (46.9%). Eighty-five percent of the nephrologists stated that insufficient attention was paid to SD and treatment options during their training. Sixty-five percent of the respondents stated to be in need of extending their knowledge on the discussing of SD. CONCLUSIONS: Dutch nephrologists do not discuss problems with sexual function routinely. The lack of knowledge, suitable education, and insufficient time are factors causing undervaluation of SD in CKD patients. Implementation of competent sexual education and raising awareness among nephrologists on the importance of paying attention to SD could improve care and QoL for patients with CKD. More research should be performed among patients and other renal care providers to develop an adequate method to enhance our current system.

Six month follow-up after 111In-DTPA-octreotide therapy in patients with progressive radioiodine non-responsive thyroid cancer: a pilot study.

BACKGROUND AND AIM: 111In-DTPA-octreotide is internalized by thyroid and neuroendocrine cancer cells via somatostatin receptor subtypes and can cause DNA damage by the emission of conversion and Auger electrons. The aim of the study was to determine the effect of 111In-DTPA-octreotide therapy in patients with progressive radioiodine non-responsive thyroid cancer in relation to 111In-DTPA-octreotide uptake by tumour localizations assessed on pre-treatment diagnostic octreotide scans. METHODS: Eleven consecutive patients, selected on positive pretreatment diagnostic scans, were treated with fixed doses of approx. 7400 MBq of 111In-DTPA-octreotide with an interval of 2-3 weeks between the doses. In one patient, the dose was adjusted because of sickle-cell disease. To assess the effects during treatment with 111In-DTPA-octreotide thyroglobulin levels were gathered from 2 years before treatment, during treatment and up to 1 year after treatment. A computed tomography scan was performed 3 months after the last treatment. RESULTS: Two patients died during and shortly after the treatment course. Death was due to a sepsis and an insulin overdose, respectively. In 44% of the patients, stable disease was achieved up to 6 months after the first treatment according to both criteria. All four had relative low pretreatment thyroglobulin values (mean value 275 microg.l), representing limited metastasized disease. In two patients biochemical stable disease was observed, whereas computed tomography showed tumour progression. CONCLUSION: Treatment with high doses of 111In-DTPA-octreotide in differentiated thyroid cancer results in a stable disease in a subgroup of patients. Our results suggest that a low pre-treatment thyroglobulin value, representing a small tumour load, may be a selection criterion for treatment.
