We describe three cases of subcutaneous phaeohyphomycosis developing in the lower limbs of renal transplant recipients shortly after transplantation. Each case presented with dark-colored nodules that subsequently ulcerated. Histopathologic examination revealed dematiaceous fungal hyphae with a surrounding granulomatous reaction. The fungi were subsequently identified as Alternaria alternatum in two cases and Phialophora richardsiae in one case. In one case, the lesions resolved during a prolonged (6-month) course of itraconazole without the requirement for surgical excision. In the other two cases, combined medical and surgical treatment resulted in cure. A review of the literature on phaeohyphomycosis is presented.

Background: In an Italian cohort of lupus podocytopathy patients, we aimed to characterize the presenting features, therapy, and outcomes, and explore differences between relapsing and non-relapsing patients.
Methods: We identified 29 patients with lupus podocytopathy from 1994 to 2023 in 11 Italian Nephrology/Rheumatology Units, and divided them into two groups: relapsing and non-relapsing. Given the limited sample size, a p-value ≤ 0.
The impact of a secondary, rare, non-pathogenic PKD1 variant on disease progression in autosomal dominant polycystic kidney disease.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by pathogenic variants in the PKD1 and PKD2 genes. Although the type of ADPKD variant can influence disease severity, rare, hypomorphic PKD1 variants have also been reported to modify disease severity or cause biallelic ADPKD. This study examines whether rare, additional, potentially protein-altering, non-pathogenic PKD1 variants contribute to ADPKD phenotypic outcomes.

Predicting the risks of progression to chronic kidney disease (CKD) stage 5 in idiopathic nephrotic syndrome (NS) and recurrence of the disease (rNS) following kidney transplantation (KT) is a key assessment to provide essential management information. NS has been categorized etiologically as genetic and immune-based. A genetic cause can be identified in ~ 30% of children with steroid-resistant NS (SRNS), a finding associated with a very low risk of rNS following KT.

Patients with kidney failure require dialysis or kidney transplantation. Kidney transplantation offers great benefits, including reduced mortality; however, many patients who wish to undergo kidney transplantation are unable to do so due to a shortage of donor organs. This shortage is a global issue, and xenotransplantation has emerged as a potential solution.
