Chronic kidney disease (CKD) and renal transplantation (RTx) are associated with a higher risk of all-cause mortality and morbidity than the general population. Apart from cardiovascular disease, infectious complications actually represent the most relevant and perhaps preventable cause of death among these specific groups of patients. The increased susceptibility to infections observed in CKD and RTx recognizes several predisposing factors such as uremia, impaired primary host immunity, sustained exposure to microbiological agents during dialysis, and, especially in RTx patients, chronic immunosuppression.
In this Special Issue of Pathogens, we will provide an updated representation of the current prevention, diagnosis, and management strategies of common and rare infections in CKD and RTx patients. In addition, we will offer further insight into future directions and emerging trends in basic, clinical, and translational science relevant to the topic.
With those aims, we invite researchers to submit high-quality works for consideration. Original articles, as well as narrative reviews of particular interest and case reports of exceptional didactical value, will be considered.
“Infectious Complications in Chronic Kidney Disease and Renal Transplant Patients: Prevention, Diagnosis, Management, and Emerging Trends” will give specialists and scientists involved in the care of renal patients the opportunity to share their experience or point of view on several critical issues, with the primary objective of improving global knowledge and patients outcome.

Abstract: Cryptococcosis ranks as the third cause of fungal infection in solid organ transplant recipients (1). Central nervous system involvement (CNS) varies greatly in this setting with rates ranging from 25% to 72% (2–4) and has been recognized to portend an increased risk of mortality (2–4). Whether these results holds true in the context of kidney transplantation (KT) has never been verified (5). Furthermore, clinical features, radiological characteristics, laboratory findings and cerebrospinal fluid analysis had yet to be scrutinized in this specific population with cryptococcal meningitidis (CM). We performed a retrospective cohort study of adult patients diagnosed with cryptococcosis after kidney transplantation between 2002 and 2019 in France. Patients’ outcomes were compared according to CM. From 2002 and 2019, 88 cases of cryptococcosis were diagnosed in France in the setting of KT and included. CNS disease was the most common organ involvement in patients with cryptococcosis (n=61, 69.3%) and in 60.7% of cases, the CNS was the only site of infection. Of these 61 patients, only 2 did not yield fungemia. When considering patients with CM, 10% (n=6) disclosed no neurological symptoms at diagnosis. , Brain imaging (MRI and / or CT) was performed in 91.7% (n=77) of the cases of CM. The predominant injury patterns consisted in vascular damage (n=13, 15.5%), parenchymal lesions (n=12) and meningeal (pachymeningeal and leptomeningeal) lesions (n=11). Patient with CM were more likely to display higher serum cryptococcosis antigen titer and were more frequently fungemic than those without CM (48.3%, p=0.029). Fever was not associated with CM (61%, p=0.27). The time between transplantation and the onset of cryptococcosis did not differ whether patients presented with CM (35.7 [14.4-72.9] months) or not (36.4 [12.3-114.8], (p = 0.8497). CM was not significantly associated with a worst survival (p=0.409). Graft survival was not significantly altered whether CM was demonstrated or not (p=0.298). CM represents the prevailing organ involvement, consistent with previous studies indicating that non-HIV patients are more prone to developing CNS disease than HIV-related cryptococcosis (6–8). Brain imaging displayed 3 main types of injury patterns with a relative predominance of vascular involvement. Prior studies have produced conflicting results with respect to the type of CNS lesion upon imaging : Singh's study (5) did not describe cerebrovascular lesions in organ transplant recipients. Conversely, recent reports (9,10) highlighted the relative importance of vascular involvement with cerebral ischemia detected in 15-43% of non-HIV patients. Fungemia is closely associated with CM and should therefore encourage clinicians to perform CSF analysis and imaging to document CM. At odds with results stemming from previous studies in other settings, we failed to demonstrate that cryptococcosis-related CNS disease conferred a worst overall survival or kidney graft survival

Abstract: Background. Since the declaration of the first wave COVID-19 pandemic, we have witnessed a dramatic reduction in the number of solid organ transplants performed worldwide. Besides the generalized healthcare crisis, this unprecedented drop of the kidney transplant (KT) rate recognizes multiple reasons such as the risk of direct viral transmission through the allograft, the perceived increase in SARS-CoV-2-related mortality and morbidity in immunocompromised hosts, and the possibility to safely remain on dialysis while waiting for an effective antiviral treatment. As a leading national healthcare service hospital operating at the epi-centrum of the COVID-19 pandemic (Milan, Italy), our institution continued the adult KT program without prespecified restrictions or limitations. We herein report our experience offering an in-depth evaluation of the outcomes of the patients transplanted or remaining on the transplant waiting list, before and during the pandemic. Methods. In this single-centre retrospective observational study with a median follow-up of 1 year, we analysed baseline characteristics and outcomes of four groups of patients: 1) subjects transplanted during the pandemic (COV-KT, n=123); 2) subjects transplanted before the pandemic (pre-COV-KT, n=122); 3) subjects awaiting a KT during the pandemic (COV-WL, n=396); and 4) subjects awaiting a KT before the pandemic (pre-COV-WL, n=427). Donors, recipients and patients in the WL were regularly screened for SARS-CoV-2 infection by PCR assay on nasal swab, BAS and/or BAL as appropriate. Results. Main demographic and clinical characteristics of the patients in the WL (pre-COV-WL or COV-WL) were equivalent whereas there was a significant difference in the prevalence of diabetes mellitus between pre-COV-KT and COV-KT (15.6% vs 4.1%; P<0.05). We observed that the pandemic did not affect post-transplant mortality or allograft loss as the number of events for each group was substantially similar (death: n=1 in pre-COV-KT vs n=2 in COV-KT; graft loss: n=6 in pre-COV-KT vs n=8 in COV-KT). On the contrary, there was an excess in mortality among COV-WL patients compared to pre-COV-WL (n=19 vs n=10). This discrepancy was primarily caused by SARS-CoV-2 infection (7/19). Patients transplanted during the pandemic exhibited slightly higher DGF rate (28% vs 22%; P=ns) and incidence of rejection (n=14 vs n=11). After 1-year follow-up, recipients in the COV-KT group showed significantly higher median serum creatinine than those in pre-COV-KT group. Median tacrolimus levels, MMF and steroid daily doses were not significantly different at any time point of the study, reflecting the fact that we did not change our immunosuppressive strategy after the onset of the pandemic. Overall, we recorded 22 COVID-19 infections in COV-KT (asymptomatic: n=5; moderate: n=13; severe: n=4), 19 in pre-COV-KT (asymptomatic: n=2: moderate: n=10; severe: n=7; and fatal: n=3), and 43 in COV-WL (asymptomatic: n=13; moderate: n=13; severe: n=15; and fatal: n=7). Infections were mostly acquired during in-centre haemodialysis or while attending outpatient clinics. Conclusions. Our study demonstrates that KT performed during the COVID-19 pandemic were not associated with increased mortality or inferior transplant-related outcomes compared to KT carried out before the pandemic. The observation that overall survivals in transplant recipients and patients remaining in the WL were substantially similar, might reassure transplant centres willing to continue their programs and might offer some reliable data for patient counselling. The perceived increase in the risk of death from SARS-CoV-2 among those awaiting a KT further supports this point of view provided that strict infection control strategies and aggressive follow-up monitoring are adopted. National multicentre studies with wider populations and different logistics are warranted.
