Although genetics play a key role in the development and progression of kidney disease, the genetic make-up of an individual does not tell the whole story. How genes are regulated, how such regulation interacts with the environment and how these phenomena are peculiar to kidney tissue are increasingly recognized as key features of critical pathologic processes such as kidney fibrosis. Find out how new developments in kidney single-cell transcriptomics can help in this journey.

Kidney transplantation offers an advantage over dialysis in terms of both survival and quality of life. However, several aspects of kidney transplant require further improvement, including tools for risk stratification of rejection and strategies to personalize immunosuppressive regimens to avoid the complications of overimmunosuppression. Furthermore, ex-vivo perfusion protocols might help achieving even better outcomes in transplanted patients. All these interesting topics are thoroughly reviewed here.

Aging is a physiological process occurring in all organisms. Aging and chronic kidney disease (CKD) are bidirectionally related. In CKD patients, premature aging at a cellular level typically manifests by accelerated shortening of telomeres and an accumulation of growth-arrested cells. Senescent cells accumulate in many renal diseases, including IgA nephropathy, several types of glomerular nephritis, hypertensive and diabetic nephropathy, and delayed graft function. Find out whether and how senescence activation also plays a role in lupus nephritis.

Chronic kidney disease is characterized by renal fibrosis. Single cell transcriptomics now allows to decipher the cellular origin of the fibrogenic niche. Distinct pericyte and fibroblast populations were found to be the major source of myofibroblasts in the human kidney. Using this approach, a novel myofibroblast-specific target in human kidney fibrosis was identified.

Hypoxia begins at the early stages of CKD and seems to predict a decline in kidney function in diabetic CKD patients. Also, in acute kidney injury hypoxia can help to explain the transition from AKI to CKD. Pharmacological HIF activators can have a role in both diabetic CKD and AKI and HIF-PH inhibitors proved to be helpful in anaemia treatment. Find out more about hypoxia and hypoxia-related drugs reading this summary.

In this summary you will find a review of the importance of pre-dialysis blood pressure (BP) evaluation. We already know that pre-dialysis BP is not sufficient to estimate the interdialytic BP, which is done by ambulatory BP monitoring. Nevertheless, both systolic and diastolic pre dialysis BP are important and with prognostic value. Let’s find why and how it was assessed.

Pregnancy in dialysis and after transplantation is a challenge to both healthcare professionals and to patients. In dialysis, pregnancy rates are low, and increase after transplantation, although low compared to the general population. Pregnancy in transplantation should be planned to reduce pregnancy and graft-related complications and infections: timing of pregnancy, adjustment of immunosuppressive therapy, schedule of prenatal visits, introduction of therapy to reduce preeclampsia risks, and intrapartum care. Postnatal care is also of utmost importance, not only to the mother, but also to the baby. Stay updated about these topics!

In nephrology we have numerous data, not only biologic (serum, urine, tissue) that can provide genomic, transcriptomic, proteomic and metabolomic data, but we also have clinical and electronic medical data, which can be analysed, incorporated in machine learning models to predict outcomes of interest. In this summary, examples of performed studies using machine learning methods are revised and their importance detailed.

Vascular calcification is associated with cardiovascular disease. Positive net calcium and phosphate balance is the hallmark of vascular calcification, suggesting that adequate phosphate control might be a priority in CKD patients. Although phosphate binders seem effective in attenuating hyperphosphatemia, evidence of potential cardiovascular benefits from their use is still lacking, especially in the dialysis population. Currently recruiting PHOSPHATE and HiLo trials are expected to provide substantiated data on the effects of targeting high or low serum phosphate levels on vascular complications, rate of hospitalization, and cardiovascular and all-cause mortality.

The renoprotective mechanisms of SGLT-2 inhibitors are not completely understood, some hypotheses have been postulated:
1) renal hemodynamic effect with attenuation of renal hyperfiltration through tubular-glomerular feedback,
2) increased urinary adenosine and prostaglandin concentrations and,
3) post-glomerular vasodilation. Research into oxygenation effects and elevation of hematocrit is underway. Although the SGLT-2 inhibitors provide an immense cardiovascular benefit, the mechanisms behind that effect are still poorly understood. It is still speculated whether natriuresis is the key factor yielding favorable cardiovascular outcomes.

Lupus nephritis (LN) affects up to 40 percent of adults with systemic lupus erythematosus. Prompt therapy in LN is associated with improved outcomes. However, unfortunately, neither demographic nor clinical or serological data can predict the onset of renal involvement in SLE. Gene expression studies (transcriptomics) performed on mouse models and patients with LN, demonstrated a shared immune cell transcriptome in these species. Several machine learning models were developed based on histological and clinical features to predict response to treatment and disease flares but could not predict the onset of the disease. Using this model, 20 mouse genes, together with the human age, gender, and the presence of Anti ds-DNA could non-invasively discriminate between patients who will and those who will not develop LN, with an accuracy of 82%. The mouse kidney-specific set of gene predictors (20 genes) could be used towards enhanced vigilance in the monitoring of LN development in SLE patients.

The European Quality study on treatment in advanced CKD (EQUAL study) is a prospective multicenter cohort study that investigated the evolvement of health-related quality of life before and after starting dialysis in older patients with kidney failure from six European countries. It included over 1,700 patients over 65 years. Individual symptom patterns varied. The most frequent ones are fatigue, decreased interest in sex, and difficulty becoming sexually aroused. These symptoms burden deteriorated in the year before starting dialysis but stabilized in the year after the start.
