Abstract Background We studied patients with IgA nephropathy (IgAN) and compared those with and without renal vasculitic lesions (RVLs). Methods From January 2006 to December 2011, patients with biopsy-proven primary IgAN at our institution were retrospectively examined and assigned to an RVL group or a no-RVL group. RVLs were defined as thromboses in arteries and/or arterioles, necrosis of capillary loops, crescent formation, and fibrinoid necrosis of small blood vessels. The association of RVLs with clinical outcomes was analyzed using multivariate models. The primary composite endpoint was end-stage renal disease or doubling of serum creatinine. Results There were 1570 patients, 50.2% (788) with RVLs and 49.8% (782) without RVLs. The RVL group was younger; had shorter disease course, more severe proteinuria and hematuria, worse renal function; and were prescribed more steroids and/or immunosuppressants. The RVL group had a greater prevalence of global glomerular sclerosis, more crescents, and a higher Oxford classification grade. A total of 501 patients in the RVL group (50.7%) and 487 in the no-RVL group (49.3%) completed follow-up. The RVL group was more likely to reach the composite endpoint after 1, 3, and 5 years (all P < 0.001). Proteinuria, anemia, low eGFR, and global and segmental sclerosis were independent predictors of progression to the composite endpoint in patients with RVLs. Conclusions Almost half of our IgAN patients had RVLs, and these patients were younger and had worse renal function, with more severe proteinuria, hematuria, and severe pathologic lesions. IgAN patients with RVLs had worse renal outcomes than those without RVLs.

Fibrillary glomerulonephritis (FGN) is a rare glomerular disease. The prognosis is usually unfavorable with nearly half of patients progressing to end-stage renal disease within 4 years. We report a case of biopsy-proven FGN characterized by an unusual benign clinical course in which a kidney biopsy, repeated after an extended follow-up of 26 years, confirmed the presence of fibrils deposition. In 1993, a 32-year-old Caucasian man was admitted to our nephrology ward because of macroscopic hematuria. Renal function was normal. Kidney biopsy displayed an FGN with mesangial pattern. The patient was treated with lisinopril, titrated for blood pressure; the therapy was maintained during 26 years of follow-up. The yearly slope of estimated glomerular filtration rate was -3.17 mL/ min). Starting from March 2018, a rapid worsening of renal function was observed and proteinuria increased up to a nephrotic range. We planned a second renal biopsy to assess the cause of the rapid change of clinical course. The diagnosis of FGN on advanced sclerosis was made, and the severity of glomerular sclerosis. We report a case of FGN with an unusually benign clinical course, characterized by a slow progression to end-stage renal disease over a very extended follow-up time; thus, to better clarify the reason for renal function worsening, a second renal biopsy was performed. The persistence of fibrils deposition confirmed the initial diagnosis of FGN, and a histological pattern characterized by global glomerular sclerosis and interstitial fibrosis has been observed.

Patients with end-stage renal disease (ESRD) experience higher rates of hospitalisation, cardiovascular events, and all-cause mortality and are more likely to require admission to the intensive care unit (ICU) than patients with normal renal function. Sepsis and cardiovascular diseases are the most common reasons for ICU admission. ICU mortality rates in patients requiring chronic hemodialysis are significantly higher than for patients without ESRD; however, dialysis patients have a better ICU outcome than those with acute kidney injury (AKI) requiring renal replacement therapy suggesting that factors other than loss of renal function contribute to their prognosis. Current evidence suggests, the longer-term outcomes after discharge from ICU may be favourable and that long-term dependence on dialysis should not prejudice against prompt referral or admission to ICU.

ABSTRACT. Primary IgA nephropathy (IgAN) is characterized by recurrent episodes of macroscopic hematuria accompanied by upper respiratory tract infections or persistent asymptomatic microscopic hematuria with or without proteinuria. IgAN may involve one or more members of a family. Three generations of a cohort of 110 patients with biopsy-proven IgAN, living in Southern Italy, were checked for urinalysis, and the relative risk (RR) of developing the disease was evaluated. A total of 19 unrelated familial, 37 suspected, and 54 sporadic cases of IgAN were identified. Renal survival was estimated by the Kaplan-Meier method for censored data and compared by use of the log-rank test. More than 50% of the patients with IgAN clustered in kindred with more than two probably affected relatives. In 19 unrelated IgAN families, 8 had single-generation (SG) and 11 multigenerational (MG) involvement showing a prevalent vertical transmission of the trait. The RR was 16 times higher in first-degree relatives (odds ratio [OR], 16.4; 95% confidence interval [CI], 5.7 to 47.8; P < 0.0001) and >2 times higher, even if NS, in second-degree relatives (OR, 2.4; 95 % CI, 0.7 to 7.9; P = 0.145). The clinical and histologic picture of familial and sporadic IgAN appeared to be similar. The 20-yr renal survival rate from the apparent onset of the disease was significantly poorer in patients with familial (41%) than in patients with sporadic (94%) IgAN (P = 0.003). Furthermore, 15-yr renal survival from the time of renal biopsy was significantly worse in familial IgAN (P = 0.02); end-stage renal disease was present in 64% of familial and only in 8% of patients with sporadic IgAN. Finally, renal survival was significantly worse in patients belonging to families with SG rather than with MG involvement (P = 0.03). These data show, for the first time, that familial IgAN may be considered a nonbenign disease that occurs frequently in first-degree relatives. Familial IgAN has a poorer outcome than sporadic IgAN. Therefore, an accurate family history and urinalysis in all family members is urgently recommended in clinical practice. This procedure might avoid late referral of subjects with persistent and underestimated urinary abnormalities and late diagnosis of the disease.

Renal Sympathetic

Sympathetic activation is a hallmark of chronic and end-stage renal disease and adversely affects cardiovascular prognosis. Hypertension is present in the vast majority of these patients and plays a key role in the progressive deterioration of renal function and the high rate of cardiovascular events in this patient cohort. Augmentation of renin release, tubular sodium reabsorption, and renal vascular resistance are direct consequences of efferent renal sympathetic nerve stimulation and the major components of neural regulation of renal function. Renal afferent nerve activity directly influences sympathetic outflow to the kidneys and other highly innervated organs involved in blood pressure control via hypothalamic integration. Renal denervation of the kidney has been shown to reduce blood pressure in many experimental models of hypertension. Targeting the renal nerves directly may therefore be specifically useful in patients with chronic and end-stage renal disease. In this review, we will discuss the potential role of catheter-based renal denervation in patients with impaired kidney function and also reflect on the potential impact on other cardiovascular conditions commonly associated with chronic kidney disease such as heart failure and arrhythmias.

Background: Worsening renal function (WRF) during heart failure (HF) hospitalization is an accepted correlate of poor prognosis. Loop diuretics are increasingly being considered as a potential cause of worsened HF outcomes, perhaps via WRF. However, the magnitude of worsening in renal function attributable to loop diuretics has not been quantified. Methods: This was a retrospective cohort study of patients who received care from a large health system and had a primary hospital discharge diagnosis of HF between Jan 1, 2000 and June 30, 2008. Patients with preexisting end-stage renal disease were excluded. Daily creatinine (Cr) measurements, furosemide dosing (only loop diuretic on hospital formulary), and radiocontrast dye studies were collected using administrative data. Day-to-day changes in Cr and MDRD estimated glomerular filtration (eGFR) calculated. The first Cr or eGFR value during hospitalization or in the emergency department was considered baseline. Generalized estimating equations were used to test the association furosemide exposure over previous 2 days to the daily change in Cr and eGFR. Covariates included undergoing radiocontrast study, age, race, gender, and baseline Cr or eGFR. Results: Among 6071 patients who met inclusion criteria there were a total of 20,645 observations. This cohort was 51% female, 68% African American, and baseline Cr was 1.36 mg/dl. Furosemide exposure was associated with an average daily increase in Cr of 0.021 mg/dL and decrease in eGFR of 0.72 ml/min/1.73m2 (per 100 mg furosemide daily, both p<0.001). Over a typical length of stay of 5 days this would amount to a Cr increase of 0.11 mg/dL or decrease in eGFR of 3.6 ml/min/1.73m 2 . Furosemide exposure accounted for only 0.4% and 0.1% of the variation in Cr and eGFR changes, respectively. Undergoing radiocontrast study, African American race, and higher age were associated with day-to-day creatinine increases (all p<0.01). Conclusions: While loop diuretic exposure is statistically associated with WRF among hospitalized HF patients, the associated magnitude of renal function change is very small, and loop diuretics explains little of the variability in renal function during hospitalization. More important predictive factors likely exist but remain unidentified.
