RESUMO

Contraception, pregnancy and fertility are seldom discussed with women receiving dialysis and the medical staff of dialysis centres. Since the majority of women on dialysis are past childbearing age, these themes are not always given proper consideration and this category of patients may be missing important information. Young women of childbearing age who are on dialysis frequently experience sexual dysfunction and hormonal disorders of the hypothalamic-pituitary-gonadal axis. In addition, dialysis often has a relevant psychological impact and affects the person's social role. Physical changes may accompany kidney failure, including the presence of a vascular or peritoneal access. The dialysis ward is not a place that facilitates privacy, and discussing contraception is not always easy, particularly in some cultural contexts, or between a male doctor and a young woman. While pregnancy and contraception are routinely addressed with women waiting for a kidney transplant, they are less frequently discussed with women on dialysis. Numerous studies have found that over half of the pregnancies in women on dialysis are unplanned. How frequently patients are seen (at each dialysis session, or during periodic visits) does not necessarily make things better, as often some issues are taken for granted or discussing them is postponed. In our centre, over 160 patients are on chronic hemodialysis (HD) and 20 are on peritoneal or home HD. Only nine women were of childbearing age in our center, all on HD. We discussed with them on counselling about pregnancy, and to ensure that all women of childbearing age would be offered counselling on contraception and pregnancy, we designed simple leaflets and an infographic, in collaboration with our nursing team and residents, as a guide and a reminder for our staff to discuss these topics with the patients.

RESUMO

Chronic kidney disease (CKD) is linked to an elevated risk of malnutrition and sarcopenia, contributing to the intricate network of CKD-related metabolic disorders. Adipokines and myokines are markers and effectors of sarcopenia and nutritional status. The aim of this study was to assess whether the adipokine-myokine signature in patients on kidney replacement therapy could help identify malnutrition and sarcopenia. The study involved three groups: 84 hemodialysis (HD) patients, 44 peritoneal dialysis (PD) patients, and 52 kidney transplant recipients (KTR). Mean age was 56.1 ± 16.3 years. Malnutrition was defined using the 7-Point Subjective Global Assessment (SGA) and the Malnutrition-Inflammation Score (MIS). Sarcopenia was diagnosed based on reduced handgrip strength (HGS) and diminished muscle mass. Concentrations of adipokines and myokines were determined using the enzyme-linked immunosorbent assay (ELISA). 32.8% of all study participants were identified as malnourished and 20.6% had sarcopenia. For malnutrition, assessed using the 7-Point SGA, in ROC analysis albumin (area under the curve (AUC) 0.67 was the best single biomarker identified. In dialysis patients, myostatin (AUC 0.79) and IL-6 (AUC 0.67) had a high discrimination value for sarcopenia, and we were able to develop a prediction model for sarcopenia, including age, albumin, adiponectin, and myostatin levels, with an AUC of 0.806 (95% CI: 0.721-0.891). Adipokines and myokines appear to be useful laboratory markers for assessing malnutrition and sarcopenia. The formula we propose could contribute to a better understanding of sarcopenia and potentially lead to more effective interventions and management strategies for dialysis patients.

RESUMO

The ongoing climate change and the ecological challenges call for sustainable medicine and, in our field, sustainable kidney care. Dialysis is life-saving and resource-consuming, and high water consumption is one of the main concerns. Circular water economy, meaning reuse and recycling of water, and recovering resources can help reducing emissions and enhancing resilience to climate change. Several actions are possible including reusing reverse osmosis reject water, employable for gardening, aquaponics or even simply for toilet flushing, or in sterilization settings, reusing spent dialysate, at least for toilet flushing, but with wider use if microbiologically purified, recovering thermal energy from spent dialysate, that can probably be done with simple devices, or using phosphate-rich spent dialysate for producing fertilizers, namely struvite. All these options may be economically sound, and all help reducing the final dialysis carbon footprint. There is room for open-minded innovative approaches to improve water-related sustainability in hemodialysis, ultimately reducing ecological impact and increasing availability.

RESUMO

Pregnancy in women living with chronic kidney disease (CKD) was often discouraged due to the risk of adverse maternal-fetal outcomes and the progression of kidney disease. This negative attitude has changed in recent years, with greater emphasis on patient empowerment than on the imperative 'non nocere'. Although risks persist, pregnancy outcomes even in advanced CKD have significantly improved, for both the mother and the newborn. Adequate counselling can help to minimize risks and support a more conscious and informed approach to those risks that are unavoidable. Pre-conception counselling enables a woman to plan the most appropriate moment for her to try to become pregnant. Counselling is context sensitive and needs to be discussed also within an ethical framework. Classically, counselling is more focused on risks than on the probability of a successful outcome. 'Positive counselling', highlighting also the chances of a favourable outcome, can help to strengthen the patient-physician relationship, which is a powerful means of optimizing adherence and compliance. Since, due to the heterogeneity of CKD, giving exact figures in single cases is difficult and may even be impossible, a scenario-based approach may help understanding and facing favourable outcomes and adverse events. Pregnancy outcomes modulate the future life of the mother and of her baby; hence the concept of 'post partum' counselling is also introduced, discussing how pregnancy results may modulate the long-term prognosis of the mother and the child and the future pregnancies.

RESUMO

Megacystis-microcolon-hypoperistalsis-syndrome (MMIHS) is a rare and early-onset congenital disease characterized by massive abdominal distension due to a large non-obstructive bladder, a microcolon and decreased or absent intestinal peristalsis. While in most cases inheritance is autosomal dominant and associated with heterozygous variant in ACTG2 gene, an autosomal recessive transmission has also been described including pathogenic bialellic loss-of-function variants in MYH11. We report here a novel family with visceral myopathy related to MYH11 gene, confirmed by whole genome sequencing (WGS). WGS was performed in two siblings with unusual presentation of MMIHS and their two healthy parents. The 38 years-old brother had severe bladder dysfunction and intestinal obstruction, whereas the 30 years-old sister suffered from end-stage kidney disease with neurogenic bladder and recurrent sigmoid volvulus. WGS was completed by retrospective digestive pathological analyses. Compound heterozygous variants of MYH11 gene were identified, associating a deletion of 1.2 Mb encompassing MYH11 inherited from the father and an in-frame variant c.2578_2580del, p.Glu860del inherited from the mother. Pathology analyses of the colon and the rectum revealed structural changes which significance of which is discussed. Cardiac and vascular assessment of the mother was normal. This is the second report of a visceral myopathy corresponding to late-onset form of MMIHS related to compound heterozygosity in MYH11; with complete gene deletion and a hypomorphic allele in trans. The hypomorphic allele harbored by the mother raised the question of the risk of aortic disease in adults. This case shows the interest of WGS in deciphering complex phenotypes, allowing adapted diagnosis and genetic counselling.

RESUMO

BACKGROUND: In Italy, nephrology residency is available in twenty-one nephrology schools, each with its own strengths and weaknesses. The present study is aimed at exploring the residents' satisfaction with their training programs. METHODS: Between April 20th and May 19th, 2021, a questionnaire on residency satisfaction consisting of 49 items was sent to 586 residents and 175 recently certified specialists (qualified to practice as nephrologists in 2019 and 2020), with a response rate of 81% and 51%, respectively. The teaching organization was contextualized with a survey involving 13 European nephrology schools. RESULTS: Most residency fellowship programs received a good rating with regard to "satisfaction", in particular for the following items: number of hospitalizations followed-up, chronic hemodialysis training, follow-up of transplanted patients, diagnosis and treatment of glomerulonephritis. The teachings that were identified as being of lower quality or insufficient intensity included vascular access management, ultrasound diagnostics and renal nutrition. The need for improvement in formal teaching programs was underlined. Young nephrologists were rather satisfied with their salary and with the quality of the work they were doing, but only few were interested in an academic career since it was generally held that it is "too difficult" to obtain a university position. Many young nephrologists who filled in the questionnaire felt that lack of experience in peritoneal dialysis and vascular access management was a barrier to finding an ideal job. Compared to other European training programs, the Italian program differs with regard to longer exposure to nephrology (as compared to internal medicine), and greater flexibility for internships in different settings, including abroad. CONCLUSIONS: This first nationwide survey on the satisfaction of residents in nephrology indicates that, despite rather good overall satisfaction, there is room for improvement to make nephrology a more appealing choice and to fulfill the needs of a growing number of renal disease patients.

RESUMO

BACKGROUND: Several scores have been developed to predict mortality at anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) diagnosis. Their prognostic value in Caucasian patients with kidney involvement (AAV-GN) remains uncertain as none has been developed in this specific population. We aimed to propose a novel and more accurate score specific for them. METHODS: This multicentric study included patients diagnosed with AAV-GN since January 2000 in four nephrology centers (recorded in the Maine-Anjou AAV-GN Registry). Existing scores and baseline characteristics were assessed at diagnosis before any therapeutic intervention. A multivariable analysis was performed to build a new predictive score for death. Its prognosis performance (area under receiving operating curve and C-index) and accuracy (Brier score) was compared with existing scores. One hundred and eighty-five patients with AAV-GN from the RENVAS registry were used as a validation cohort. RESULTS: A total of 228 patients with AAV-GN from the Maine-Anjou registry were included to build the new score. It included the four components most associated with death: age, history of hypertension or cardiac disease, creatinine and hemoglobin levels at diagnosis. Overall, 194 patients had all the data available to determine the performance of the new score and existing scores. The new score performed better than the previous ones in the development and in the validation cohort. Among the scores tested, only Five-Factor Score and Japanese Vasculitis Activity Score had good performance in predicting death in AAV-GN. CONCLUSIONS: This original score, named DANGER (Death in ANCA Glomerulonephritis-Estimating the Risk), may be useful to predict the risk of death in AAV-GN patients. Validation in different populations is needed to clarify its role in assisting clinical decisions.
