RESUMEN

Heart failure (HF) and chronic kidney disease (CKD) are two pathological conditions with a high prevalence in the general population. When they coexist in the same patient, a strict interplay between them is observed, such that patients affected require a clinical multidisciplinary and personalized management. The diagnosis of HF and CKD relies on signs and symptoms of the patient but several additional tools, such as blood-based biomarkers and imaging techniques, are needed to clarify and discriminate the main characteristics of these diseases. Improved survival due to new recommended drugs in HF has increasingly challenged physicians to manage patients with multiple diseases, especially in case of CKD. However, the safe administration of these drugs in patients with HF and CKD is often challenging. Knowing up to which values ​​of creatinine or renal clearance each drug can be administered is fundamental. With this review we sought to give an insight on this sizable and complex topic, in order to get clearer ideas and a more precise reference about the diagnostic assessment and therapeutic management of HF and CKD.

RESUMEN

PURPOSE: The study aimed to present the results of a Delphi consensus involving Italian experts focusing on the management of hypophosphatemia in adults. METHODS: A multidisciplinary advisory board of nine physicians, experts in hypophosphatemia management, was established. Next, a literature search was performed to identify international guidelines, consensus, and clinical pathways, which were later presented to the advisory board. Collaboratively, the advisory board and authoring team selected key statements for the consensus process and focused on areas of uncertainty related to the management of hypophosphatemia. The advisory board also indicated the experts to be invited to participate in the consensus process. The Delphi method was employed to reach a consensus. RESULTS: The literature search yielded one guideline, five consensus documents, and one clinical pathway. While our search strategy aimed to identify documents on the management of all types of hypophosphatemia, most of the guidelines and consensus documents retrieved focused on X-linked hypophosphatemia. The consensus process focused on 11 key issues, achieving strong convergence (over 70% consensus) in the first Delphi round for 8 out of the 11 statements. Three statements proceeded to the second round, with strong agreement reached for two. Notably, consensus was not reached for the statement concerning the measurement of fibroblast growth factor 23 for diagnostic purposes. CONCLUSION: The study revealed that the community of clinical experts is well-informed and in agreement regarding hypophosphatemia management. It emphasized the importance of developing clear national guidance documents to support clinicians and multidisciplinary teams in patient management. These documents are crucial not only for healthcare professionals but also for those responsible for defining pathways and services, facilitating a more accurate management of hypophosphatemic patients.

RESUMEN

BACKGROUND/AIMS: The new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes a wide spectrum of effects, including acute kidney injury (AKI) in up to 40% of hospitalized patients. Given the established relationship between AKI and poor prognosis, whether AKI might be a prognostic indicator for patients admitted to the hospital for SARS-CoV-2 infection would allow for a straightforward risk stratification of these patients. METHODS: We analyzed data of 623 patients admitted to San Raffaele Hospital (Milan, IT) between February 25 and April 19, 2020, for laboratory-confirmed SARS-CoV-2 infection. Incidence of AKI at hospital admission was calculated, with AKI defined according to the KDIGO criteria. Multivariable Cox regression models assessed the association between AKI and overall mortality and admission to the intensive care unit (ICU). RESULTS: Overall, 108 (17%) patients had AKI at hospital admission for SARS-CoV-2 infection. After a median follow-up for survivors of 14 days (interquartile range: 8, 23), 123 patients died, while 84 patients were admitted to the ICU. After adjusting for confounders, patients who had AKI at hospital admission were at increased risk of overall mortality compared to those who did not have AKI (hazards ratio [HR]: 2.00; p = 0.0004), whereas we did not find evidence of an association between AKI and ICU admission (HR: 0.95; p = 0.9). CONCLUSIONS: These data suggest that AKI might be an indicator of poor prognosis for patients with SARS-CoV-2 infection, and as such, given its readily availability, it might be used to improve risk stratification at hospital admission.

RESUMEN

OBJECTIVE: Irisin is a circulating myokine released from skeletal muscles after physical exercise. Irisin production decreases during the course of chronic kidney disease (CKD) as a potential consequence of sarcopenia and physical inactivity. METHODS: This observational study explored the relationship of serum irisin with cardiovascular outcome in 79 patients with stage 3-5 CKD. RESULTS: Serum irisin was significantly higher in healthy subjects (n = 20) than that in CKD patients (7 ± 2 vs. 3.1 ± 0.9 µg/mL; P = .0001) and was higher in patients with CKD stage 3 (3.2 ± 1 µg/mL) than in patients at stage 4 and 5 taken together (n = 36, 2.8 ± 0.7 µg/mL, P = .05). Patients in the lowest serum irisin tertile had lower serum 1,25(OH)2D levels (21 ± 11 pg/mL) than patients in the middle (30 ± 13 pg/mL; P = .005) and the highest tertile (27 ± 14 pg/mL; P = .047). Patients in the highest tertile had lower Kauppila score (10.6 ± 6.9) than patients in the middle (11.8 ± 5.5; P = .007) and the lowest tertile (6.9 ± 6.8; P = .043). Twenty patients suffered from cardiovascular events during a 3-year follow-up. A Cox regression model using age, body weight, presence of diabetes mellitus, gender, Kauppila calcification score, serum values of FGF23 (as logarithm), phosphate, sclerostin, albumin and cholesterol, estimated glomerular filtration rate, and serum irisin tertiles as covariates showed that patients in the highest tertile of serum irisin had a lower cardiovascular risk than patients in the middle tertile (B, 2.38; odds ratio, 10.8; 95% confidence interval, 1.65-58.13; P = .013) or in the lowest tertile (B, 1.61; odds ratio, 5; 95% confidence interval, 1.09-22.83; P = .038). CONCLUSIONS: These findings suggest that serum irisin may be a marker of cardiovascular outcome in patients with CKD.

RESUMEN

The recent COVID-19 pandemic has had a significant impact on the population worldwide. Patients with chronic kidney disease treated with kidney replacement therapy were no exception because they were considered highly vulnerable due to multiple comorbidities. The consequences of the physical, biological, and ecological system on the environment as a result of human activity represent a huge global health care danger. The purpose of this article is to identify strategies that improve environmental sustainability, improve prevention of COVID-19 infection in dialysis centers, and improve the environmental impact of hemodialysis centers.

RESUMEN

The northern fowl mite (NFM),Ornithonyssus sylviarum, is the most common ectoparasite of laying hens in North America. Infestation can cause a reduction in egg production, egg weights, and feed conversion efficiency. However, there is a lack of information on the effects of NFM on hen physiology, physical condition, and egg quality. Singly caged beak-trimmed White Leghorn hens (N=32) were infested with mites at 25 wk of age. The condition of each hen was assessed at wk 0 (infestation) and wk 5 and 7 post-infestation to determine comb temperatures and feather, skin, and comb condition. Heterophil-lymphocyte (H/L) ratios and body weight (BW) were evaluated at wk 0 and wk 1, 3, 5, and 7 post-infestation. Egg weight, egg specific gravity, yolk color, Haugh unit (HU), and eggshell thickness were determined prior to infestation (wk -1) and at 1, 3, 5, and 7 wk post-infestation. The H/L ratio (P<0.0001), HU (P<0.0001), and egg specific gravity (P=0.001) were lowest, and the egg yolk color was lightest (P=0.087) at wk 5, the peak of infestation. At wk 5 and 7, more than 65% of the hens had red skin and more than 75% had scabs on the vent; in addition more than 84% had grey-black vent feathers. There were no effects of infestation on comb color, comb temperature, feather cover, BW, or eggshell thickness. It was concluded that infestation with NFM has negative effects on interior egg quality and hen integument. A decrease in H/L ratio was also observed at the peak of infestation. However, the effects of NFM on the immune system are unclear, and H/L ratio might not be a good stress measure in hens highly infested with NFM.

RESUMEN

The effects of beak condition on ectoparasite populations and preening in laying hens were investigated. Beak-trimmed and beak-intact caged Hy-Line W-36 hens were infested with either chicken body lice or northern fowl mites using a 2×2 factorial design with 4 replicate cages (each containing 2 hens)/treatment: 1) BTL: (beak-trimmed lice-infested); 2) BTM: (beak-trimmed mite-infested); 3) BIL: (beak-intact lice-infested); and 4) BIM: (beak-intact mite-infested). Mite scores and lice numbers were estimated weekly. Hens were video recorded the wk before infestation and at wk 6 and 9 post-infestation. Time spent preening on 6 body areas and in total were analyzed using a repeated measures ANOVA. There was a wk×beak condition interaction for lice loads, with BTL harboring approximately 17 times more lice than BIL from wk 7 to 10 post-infestation (P<0.0001). Beak condition affected mite loads (P<0.0001), with BTM having a higher mite score (3.8±0.26) than BIM (1.4±0.26). At peak infestation, BTL spent more total time preening (P=0.02, s±SE: 232.1±37.6) than prior to infestation (33.9±37.6) and directed their preening behavior towards the vent. In contrast, BIL (73.9±37.6), BTM (9.4±1.6), and BIM (8.6±1.6) did not increase total time spent preening over pre-infestation levels (103.6±37.6, 5.8±1.6, 6.7±1.6 respectively), although BTM did redirect their preening behavior toward the vent. This study confirmed previous studies showing that an intact beak is important for reducing ectoparasite infestations. Preening behavior increased in response to lice infestation, but only in beak-trimmed hens; preening behavior and louse load were correlated at peak infestation. In contrast, mite infestation did not lead to increased preening, and there was no correlation between preening and mite load. However, both lice- and mite-infested hens directed preening behavior predominantly towards the vent where these parasites are typically found.

RESUMEN

Currently, no animal-based protocol for on-farm welfare assessment of commercial turkeys is available. The birds' size and flighty nature make obtaining a representative sample using traditional methods difficult. The transect walks (TW) approach provides a potential alternative for on-farm assessments of turkey welfare. We compared the TW approach with a traditional method, and data collected as the birds were moved out of the house during the load out process (L). Ten commercial 19- to 20-week-old Hybrid turkey flocks were evaluated (1 flock/house/farm). Half of the flocks were housed on farms deemed as "faring well" by the company, the other half were on "suboptimal" farms. Each house was subdivided longitudinally into 4 transects. Two observers walked the transects in random order, recording the total number of birds per transect that were immobile; lame; aggressive towards a mate; interacting with humans; with visible head, vent, or back wounds; engaging in mounting behaviors; small; featherless; dirty; sick; terminal; or dead. Flocks were re-evaluated on the same day using the individual sampling method (S), where randomly selected birds were scored as they took 10 steps. Flocks were re-assessed within 48 h of the transect evaluation, as birds were funneled out of the house during load out. Using ANOVAs we determined the effects of observers, method, management, and their interactions on proportions of turkeys per house within each category. Outcome parameters were not affected by management (P>0.05 for all) or observer (P>0.05 for most), but an assessment method effect was detected (P<0.05). S differed from the 2 other methods (P<0.05) for most parameters except aggression towards a mate, back wounds, dirty, sick, and vent wounds. Differences were not detected between data collected using TW and during L, except for dead (P=0.0007) and immobile (P=0.007). Results suggest that the TW method is a promising tool for on-farm turkey welfare assessment as it produced results similar to those obtained at L when all birds could be scored individually.

RESUMEN

BACKGROUND: Nephrolithiasis is more frequent and severe in obese patients from different western nations. This may be supported by higher calcium, urate, oxalate excretion in obese stone formers. Except these parameters, clinical characteristics of obese stone formers were not extensively explored. AIMS: In the present paper we studied the relationship between obesity and its metabolic correlates and nephrolithiasis. MATERIALS AND METHODS: We studied 478 Caucasian subjects having BMI ≥ 25 kg/m². The presence of nephrolithiasis, hypertension, diabetes mellitus and metabolic syndrome were noted. They underwent measurements of anthropometry (BMI and waist circumference, body composition), serum variables (fasting glucose, serum lipids and serum enzymes) and Mediterranean diet (MedDiet) nutritional questionnaire. RESULTS: 45 (9.4%) participants were stone formers. Subjects with high serum concentrations of triglycerides (≥ 150 mg/dl), fasting glucose (> 100 mg/dl) and AST (>30 U/I in F or >40 U/I in M) were more frequent among stone formers than non-stone formers.Multinomial logistic regression confirmed that kidney stone production was associated with high fasting glucose (OR = 2.6, 95% CI 1.2-5.2, P = 0.011), AST (OR = 4.3, 95% CI 1.1-16.7, P = 0.033) and triglycerides (OR = 2.7, 95% CI 1.3-5.7, P = 0.01). MedDiet score was not different in stone formers and non-stone formers. However, stone formers had a lower consumption frequency of olive oil and nuts, and higher consumption frequency of wine compared with non-stone formers. CONCLUSIONS: Overweight and obese stone formers may have a defect in glucose metabolism and a potential liver damage. Some foods typical of Mediterranean diet may protect against nephrolithiasis.

RESUMEN

BACKGROUND: Calcium nephrolithiasis is a multifactorial disease with a polygenic milieu. Association studies identified genetic polymorphisms potentially implicated in the pathogenesis of calcium nephrolithiasis. The present article reviews the mechanisms of calcium stone formation and the potential contribution of gene polymorphisms to lithogenic mechanisms. SUMMARY: Endoscopy observations suggested that precipitation of calcium-oxalate on the Randall's plaque at the papilla surface may cause idiopathic calcium-oxalate stones. The Randall's plaque is a hydroxyapatite deposit in the interstitium of the kidney medulla, which resembles a soft tissue calcification. Conversely, calcium-phosphate stones may develop from crystalline deposits located at the tip of the Bellini duct. Polymorphisms of eleven genes have been associated with stones in genome-wide association studies and replicated candidate-gene association studies: VDR, SLC34A1, SLC34A4, CLDN14, and CaSR genes coding for proteins regulating tubular phosphate and calcium reabsorption; CaSR, MGP, OPN, PLAU, and UMOD genes coding for proteins preventing calcium salt precipitation; AQP1 gene coding for a water channel in the proximal tubule. The renal activity of the last gene, DGKH, is unknown. Polymorphisms in these genes may predispose to calcium-oxalate and -phosphate stones by increasing the risk of calcium-phosphate precipitation in the tubular fluid. Key Messages: Genetic findings suggest that tubular fluid supersaturation with respect to calcium and phosphate predisposes to calcium-oxalate stones by triggering cellular mechanisms that lead to the Randall's plaque formation.

RESUMEN

PURPOSE: In patients with chronic kidney disease (CKD), renal osteodystrophy may be associated with a progressive bone mass loss that increases fracture risk. Denosumab, a monoclonal antibody inhibiting osteoclast activity, is an antiresorptive medication used for the treatment osteoporosis. METHODS: Its efficacy and safety were initially established in the FREEDOM study, showing a significant reduction in incident fractures in osteoporotic women treated with denosumab. Subsequent post hoc analyses showed its efficacy in patients stratified by kidney function, but these analyses did not include patients with advanced stages of CKD. The capability of denosumab in improving bone mineral density in uremic patients was evaluated in 12 studies including 461 dialysis patients with low bone mineral density. The improvement of bone mineral density was the final end point in these studies assessed during a follow-up of 6-60 months. Nine of these studies did not have hyperparathyroidism among criteria for patient inclusion and their participants may have low-turnover bone disease. Despite current recommendations, no patients underwent bone biopsy before denosumab therapy. RESULTS: Overall, findings in these studies suggest that denosumab is a viable option for promoting bone mass recovery in patients with advanced stages of CKD having either high or low serum levels of PTH. However, the increase of bone mineral density was lower in patients with low serum markers of bone turnover at baseline. These studies also highlighted the need for calcium and vitamin D supplementation to prevent hypocalcemia that remains a serious concern. CONCLUSIONS: Denosumab emerges as a potentially safe and effective option for enhancing bone health in CKD patients.

RESUMEN

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic kidney disease and the 4th leading cause of renal replacement therapy in the world. ADPKD is a systemic disorder as cysts may develop in several organs. Liver cysts are the most common extrarenal manifestations and are often incidentally detected. Even though cysts do not influence liver function, they can grow to a very great size and can significantly enlarge liver volume, causing structural distortion of the biliary tree and patient discomfort due to the mass effect. Nephrectomy is frequently considered in preparation for renal transplantation in patients with remarkable kidneys' enlargement. There are currently no globally recognized clinical guidelines for nephrectomy. Although cysts do not normally affect liver function in ADPKD, after nephrectomy cases of liver fibrosis and Budd-Chiari have been reported. These are uncommon disorders due to the obstruction of the blood flow in the hepatic venous causing spleen and liver volume enlargement, portal hypertension, and hepatic cirrhosis. Case Presentation: We present a case of hepatic fibrosis with splenomegaly and severe pancytopenia as a tardive complication after bilateral nephrectomy in 47-year-old ADPKD patient. Conclusion: This finding underscores the critical significance of meticulously examining the anatomical relationship between polycystic kidneys and the liver before performing nephrectomy. Additionally, it highlights the importance of assessing liver involvement and associated complications. By integrating liver assessment into the criteria, we can significantly enhance patient care and improve the overall management of ADPKD before kidney transplantation.

RESUMEN

This article constitutes a review of the existing literature on the potential correlation between autosomal dominant polycystic kidney disease (ADPKD) and intraductal papillary mucinous neoplasms (IPMN) of the pancreas. Additionally, it presents a clinical case where familiarity for both pathologies was observed, derived from the direct experience of our clinic, reinforcing the hypothesis of a possible common pathogenetic pathway. The review focuses on the potential genetic correlation between these two pathologies within the realm of ciliopathies, emphasizing the importance of targeted screening and monitoring strategies to detect pancreatic complications early in patients with ADPKD. Furthermore, it highlights the complexity in the clinical management of these rare conditions and underscores the importance of early diagnosis in optimizing clinical outcomes.

RESUMEN

This review navigates the intricate relationship between gender, hormonal influences, and the progression of autosomal dominant polycystic kidney disease (ADPKD), highlighting the limited literature on this crucial topic. The study explores the impact of female sex hormones on liver and renal manifestations, uncovering gender-specific differences in disease progression. Actually, hormonal therapy in women with ADPKD remains a challenging issue and is a source of concern regarding its potential impact on disease outcomes, particularly at the hepatic level. Notably, women with ADPKD exhibit a slower renal disease progression compared to men, attributed to hormonal dynamics. This review sheds light on the role of estrogen in regulating pathways of the renin-angiotensin-aldosterone system, revealing its complex interplay and implications for cardiovascular and renal health. Therapeutic considerations for fertile women with ADPKD, including contraception options, are discussed, emphasizing the necessity for personalized approaches. In the postmenopausal phase, the review evaluates the role of hormonal replacement therapy, considering its potential benefits and risks in the context of ADPKD. The review concludes by underscoring the imperative need for tailored treatment approaches for ADPKD patients, considering individual risks and benefits. The scarcity of literature underlines the call for further research to enhance our understanding of optimal hormonal therapies in the context of ADPKD, ultimately paving the way for innovative and personalized therapeutic interventions.

RESUMEN

Idiopathic calcium nephrolithiasis is a multifactorial disease with a complex pathogenesis due to genetic and environmental factors. The importance of social and health effects of nephrolithiasis is further highlighted by the strong tendency to relapse of the disease. Long-term prospective studies show a peak of disease recurrence within 2-3 years since onset, 40-50% of patients have a recurrence after 5 years and more than 50-60% after 10 years. International nutritional studies demonstrated that nutritional habits are relevant in therapy and prevention approaches of nephrolithiasis. Water, right intake of calcium, low intake of sodium, high levels of urinary citrate are certainly important for the primary and secondary prevention of nephrolithiasis.

RESUMEN

Burosumab is a monoclonal anti-FGF23 antibody used to treat patients with X-linked hypophosphatemic rickets (XLH). Its effect on serum phosphate and physical performance was compared in patients during a 6-month treatment with burosumab. Eight adult patients with XHL were treated with burosumab (1 mg/kg s.c. every 28 days). In the first 6 months of treatment, calcium-phosphate metabolism variables were measured, and muscle performance (tested with chair and walking test) and quality of life (tested with fatigue, BPI-pain and BPI-life questionnaires) were estimated. A significant increase in serum phosphate was observed during the treatment. From the 16th week, serum phosphate became significantly lower than its value in the 4th week. No patients had serum phosphate below the normal range at the 10th week, but seven patients were hypophosphatemic in the 20th and 24th week. All patients improved the execution time of the chair test and walking test, which reached a plateau after the 12th week. BPI-pain and BPI-life scores significantly decreased from baseline to the 24th week. In conclusion, a six-month burosumab treatment may significantly improve the general condition and physical performance of adult patients with XLH; this improvement was more stable and more indicative of treatment efficacy than that of serum phosphate.

RESUMEN

BACKGROUND: Primary hyperoxaluria is a genetic disorder of the metabolism of glyoxylate, the precursor of oxalate. It is characterized by high endogenous production and excessive urinary excretion of oxalate, resulting in the development of calcium oxalate nephrolithiasis, nephrocalcinosis, and, in severe cases, end-stage kidney disease and systemic oxalosis. Three different forms of primary hyperoxaluria are currently known, each characterized by a specific enzymatic defect: type 1 (PH1), type 2 (PH2), and type 3 (PH3). According to currently available epidemiological data, PH1 is by far the most common form (about 80% of cases), and is caused by a deficiency of the hepatic enzyme alanine:glyoxylate aminotransferase. METHODS: A survey on rare forms of nephrolithiasis and nephrocalcinosis with a focus on primary hyperoxaluria in the setting of Italian Nephrology and Dialysis Centers, using an online questionnaire, was recently conducted by the Project Group "Rare Forms of Nephrolithiasis and Nephrocalcinosis" of the Italian Society of Nephrology, with the aim of assessing the impact and management of this disorder in clinical practice in Italy. RESULTS: Forty-five public and private Italian Centers participated in the survey, and responses to the questionnaire were provided by 54 medical professionals. The survey results indicate that 21 out of the 45 participating Centers are managing or have managed primary hyperoxaluria patients, most of whom are on dialysis, or are recipients of kidney transplants. CONCLUSIONS: The data of this survey indicate the need to implement genetic testing in suspected cases of primary hyperoxaluria, not only in the setting of dialysis or transplantation, but also with the aim of encouraging early diagnosis of PH1, which is the only type of primary hyperoxaluria for which specific drug therapy is currently available.

RESUMEN

We present the case of a 41-year-old man patient diagnosed with solitary left kidney with few cysts. He has a family history of unilateral renal agenesis (URA) but no for autosomal dominant polycystic kidney disease (ADPKD). Genetic testing revealed PKD1 gene intron 11 heterozygous nucleotide variant c.2854-23G>T, but no gene mutation implicated in URA. Just eight cases of ADPKD with one kidney have been recorded globally. PC1 and PC2 disruption, causing primary cilia malformation or absence resulting in relevant in the first embryonic development alteration. Cillia's crucial significance in many diseases will require more research.

RESUMEN

Background. Polycystic kidney disease (ADPKD) is the most common monogenic cause of End Stage Renal Disease (ESRD), and, thus, of kidney transplantation and dialysis. Educational interventions aimed to improve adherence to therapy, physical performance, and adequate food intake in patients can slow down disease progression by developing self-care skills, which are useful to promote their autonomy while aligning their life plans and required treatments. The aim of this review is to analyze the adherence of patients with polycystic kidney to pharmacological therapy, low-sodium diet, and physical activity, as evidenced in the clinical literature to guide structured educational interventions. Methods. We conducted a literature review from 01/09/2021 to 30/12/2022 through the combination of free keywords and MeSH terms on the databases: PubMed, CINAHL and Cochrane. Results. Findings in medical literature show that physical activity can improve blood pressure control and a low-sodium diet can slow down the progression towards ESRD. Furthermore, although patients may adhere to the complex drug therapy, unresolved educational demands concern choices and behaviors of daily life that, involving the sphere of feelings and emotions, can evolve into manifestations of anxiety and stress. Conclusion. Among ADPKD patients a personalized educational support, considering disease stage and psychological factors, may enable them to acquire knowledge, skills, and behaviors that can improve clinical outcomes.
