How histopathological diagnosis interacts with kidney ultrasound parameters and glomerular filtration rate.

The evaluation of estimated GFR (eGFR) is a pivotal staging step in patients with chronic kidney disease (CKD), and renal ultrasound plays an important role in diagnosis, prognosis and progression of CKD. The interaction between histopathological diagnosis and ultrasound parameters in eGFR determination has not been fully investigated yet. The study examined the results of native kidney biopsies performed in 48 Italian centers between 2012 and 2020.

[Examination of Urinary Sediment in a Patient with Lupus-Like HIV-Associated Immune Complex Kidney Disease (HIVICK) - Case Report and Review of the Literature].

Renal involvement is very common in patients with HIV infection. The phenotype varies from the most frequently "collapsing" variant of focal and segmental glomerulosclerosis (FSGS) to "lupus-like HIV-immune complex kidney disease" (HIVICK). The latter is characterized by a histological picture that recalls lupus nephropathy.

[Collapsing Glomerulopathy Secondary to Anabolic Steroids for Bodybuilding: A Case Series].

The abuse of anabolic androgenic steroids (AAS) for competitive (and non-competitive) purposes for bodybuilding practice is increasingly common. The consequences of these substances on the various organs are only partially known. Cases of FSGS following the use of AAS have been reported in the literature, even with evolution to ESKD.

[Anti-MBG crescentic glomerulonephritis with negative immunofluorescence: case report and literature review].

Anti-glomerular basement membrane (anti-GBM) antibody disease is a rapidly progressive glomerulonephritis characterized by (i) positivity to anti-GBM in serum reacting with a specific antigen present in type IV collagen at both the glomerular and alveolar levels (ii) presence of crescent on light microscopy and positivity to linear deposits of IgG and C3 on immunofluorescence. In the classic variant, the clinic is that of a nephro-pneumological syndrome but there are variants. Rarely, the glomerular damage is pauci-immune.

[Inflammation in kidney diseases].

The term "inflammation" is certainly one of the oldest medical terms still in use. However, its meaning has changed over the centuries. This work gives a historical and critical review of the concept of inflammation, with special reference to kidney diseases.

Interaction between phosphorus and parathyroid hormone in non-dialysis CKD patients under nephrology care.

Background: Whether the traditional treatment of chronic kidney disease (CKD)-mineral and bone disorder is effective in the setting of tertiary nephrology care is an unexplored question. We evaluated phosphate, calcium and PTH levels during the first year of nephrology care and the prognostic role of month-12 levels in non-dialysis patients referred prior to availability of the novel P binders.

Methods: We studied a historical cohort of consecutive patients with CKD stage 3-5 at referral (baseline), and after 6 and 12 months of nephrology care; thereafter, patients were followed for renal survival (time to death or end-stage renal disease).

[Chronic kidney dysfunction in the elderly patient: physiological process or disease?].

The last few years have seen a steady rise in numbers of patients with chronic kidney disease (CKD), mainly because of the increased prevalence of older patients. Today, most new diagnoses of CKD are made in patients belonging to the large subgroup of subjects aged 65 years or over, who often present with mild-to-moderate CKD. Given the recent rise in numbers of elderly CKD patients referred to American renal clinics, the American Society of Nephrology has recently endorsed a study group dedicated to this group of patients, Geriatric Nephrology, with the aim of increasing knowledge on CKD in the elderly and subsequently improving the clinical management of older patients.

Survey of hidden costs of dialysis in Italian for-profit and not-for-profit centers.

Background: Chronic dialysis exposes patients to several procedures that may influence lifestyle and quality of life. These hidden costs, however, have never been evaluated.

Aim And Methods: To compare the costs related to diagnostic and therapeutic procedures between not-for-profit (nFP) and for-profit (FP) dialysis care systems, we mailed to Italian nephrology units a questionnaire on modalities of medical prescriptions and reservations, waiting time for tests and modalities of drugs distribution.
