Contrary to the general population, most infections occurred during the first pandemic wave and, specifically, during the first month, when personal protective equipment (PPE) shortages were more severe. Factors associated with infection in univariate analysis were younger age (P = 0.004), work in non-nephrology departments (P = 0.045), higher exposure to coronavirus disease 2019 patients (P < 0.001), lack of appropriate PPE (P < 0.001) and non-O ABO blood group. In an adjusted multivariate model, only lack of appropriate PPE remained predictive of infection [hazard ratio 3.5 (95% confidence interval 1.9-6.8), P < 0.0001].

SARS-CoV-2 infection was frequent among nephrologists, was frequently diagnosed late and was associated with working conditions.

Data on the activation of the acute inflammatory response and its clinicopathological associations in idiopathic nephrotic syndrome (INS) are scarce and discordant.

To analyse the associations between the activation of the inflammatory response, the clinicopathological characteristics of disease and the response to treatment with steroids in patients with INS.

A total of 101 patients with INS due to minimal change disease (MCD;
= 44), focal segmental glomerulosclerosis (FSGS;
= 33) and membranous nephropathy (MN;
= 24) and 50 healthy controls were included. At diagnosis, we measured the levels of haemopexin (Hx), haptoglobin (Hgl), interleukin-6 (IL-6), soluble urokinase-type plasminogen activator receptor (suPAR), tumour necrosis factor-α (TNF-α), soluble IL-1 receptor, interferon-γ and C-reactive protein. We analysed their clinicopathological associations. In MCD and FSGS patients, we determined the association between the levels of these variables and steroid resistance.

The levels of Hx, Hgl, TNF-α, suPAR and IL-6 were higher in patients with INS than in healthy controls, and were not associated with proteinuria, estimated glomerular filtration rate or serum albumin. In MCD and FSGS patients, Hx, Hgl, IL-6 and TNF-α levels were similar and significantly higher than in MN patients. In patients with MCD and FSGS, multivariate analyses identified FSGS and the levels of Hx, Hgl or IL-6 as independent predictors of steroid resistance.

The activation of the inflammatory response in patients with INS is heterogeneous and more prevalent in MCD or FSGS patients than in those with MN. In MCD and FSGS, elevated levels of Hx, Hgl or IL-6 are independently associated with steroid resistance.

Ischaemia-reperfusion (I/R) damage is a relevant cause of delayed graft function (DGF). Complement activation is involved in experimental I/R injury, but few data are available from kidney transplant (KT) patients. We studied the dynamics of membrane attack complex (C5b-9) as a soluble fraction (SC5b-9) and the histological deposit pattern of C3b, complement Factor H (FH) and C5b-9 in DGF patients.

We evaluated SC5b-9 levels in 59 recipients 38 with immediate graft function and 21 with DGF. The SC5b-9 was measured at admission for KT and 7 days after KT. DGF-kidney biopsies (
 = 12) and a control group of 1-year protocol biopsies without tissue damage (
 = 4) were stained for C5b-9, C3b and FH.

SC5b-9 increased significantly in DGF patients (Day 0 6621 ± 2202 mAU/L versus Day 7 9626 ± 4142  mAU/L; P = 0.006), while it remained stable in non-DGF patients. Days 0-7 increase >5% was the better cut-off associated with DGF versus non-DGF patient discrimination (sensitivity = 81%). In addition, SC5b-9 increase was related to DGF duration and worse graft function, and independently associated with DGF occurrence. SC5b-9, C3b and FH stains were observed in tubular epithelial cells basal membrane. DGF-kidney biopsies showed a more frequently high-intensity stain, a higher number of tubules with positive stain and larger perimeter of tubules with positive stains for SC5b-9, C3b and FH than control patients.

Both SC5b-9 levels and SC5b-9, C3b and FH deposits in tubular epithelial cells basal membrane are highly expressed in patients experiencing DGF. SC5b-9 levels increase could be useful as a marker of DGF severity.

The use of kidneys from elderly controlled donation after circulatory death (cDCD) donors has increased significantly in recent years. Concerns about outcomes achieved with these elderly cDCD kidneys have arisen. We aimed to compare outcomes from elderly cDCD kidney transplant recipients (KTrs) and elderly donation after brain death donors (DBDs) in KTrs.

We conducted a single-centre retrospective study including 87 cDCD-KTrs (46 from donors ≥65 years of age and 41 from <65 years) and 126 DBD-KTrs from donors ≥65 years of age from 2013 through 2017). Young cDCD-KTrs were used as controls. The median follow-up was 27.1 months for all cDCD-KTrs and 29.7 months for DBD-KTrs ≥65 years of age.

Donors >65 years of age represented more than half of our global cDCD cohort (52.9%). KTs from elderly cDCDs had similar rates of delayed graft function, primary non-function and vascular complications compared with young cDCD-KTrs and elderly DBD-KTrs. Short and medium-term graft survival from elderly cDCD kidneal studies are needed to assess long-term outcomes.
Kidney transplantation (KTx) is a strong trigger for the development of either recurrent or
atypical haemolytic uraemic syndrome (aHUS). L-glutamate According to previous studies, eculizumab (ECU) is effective for prophylaxis and for treatment of recurrence.

We evaluated the experiences of Spanish patients with recurrent and
aHUS associated with KTx, treated or not treated with ECU. In the
group, we classified patients as having early
(during the first month) or late
aHUS (subsequent onset).

We analysed 36 cases of aHUS associated with KTx. All of the 14 patients with pre-KTx diagnosis of aHUS were considered to have high or moderate risk of recurrence. Despite receiving grafts from suboptimal donors, prophylactic ECU was effective for avoiding recurrence. The drug was stopped only in two cases with low-moderate risk of recurrence and was maintained in high-risk patients with no single relapse. There were 22
aHUS cases and 16 belonged to the early
group. The median time of onset in the late group was 3.
