RESUMO

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.

RESUMO

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic kidney disease. Its main feature is the progressive enlargement of both kidneys with progressive loss of kidney function. ADPKD is the fourth leading cause of terminal renal failure in the world. Even today there are still uncertainties and poor information. Patients too often have a renunciatory and passive attitude toward the disease. However, there are currently no internationally accepted clinical practice guidelines, and there are significant regional variations in approaches to the diagnosis, clinical evaluation, prevention, and treatment of ADPKD. Therefore, we believe it is important to point out the conduct of our specialist outpatient clinic for ADPKD, which from the beginning has developed a multidisciplinary approach (nephrologists, geneticists, psychologists, radiologists, nutritionists) to face the disease at 360° and therefore not only from a purely nephrological point of view. Such a strategy not only enables patients to receive a timely and accurate diagnosis of the disease, but also ensures that they will receive a thorough and focused follow-up over time, that can prevent or at least slow down the disease in its evolution providing patients with a serene awareness of their condition as much as possible.

RESUMO

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.

RESUMO

The SARS-CoV-2 (Covid-19) has infected about 124 million people worldwide and the total amount of casualties now sits at a staggering 2.7 million. One enigmatic aspect of this disease is the protean nature of the clinical manifestations, ranging from total absence of symptoms to extremely severe cases with multiorgan failure and death. Chronic Kidney Disease (CKD) has emerged as the primary risk factor in the most severe patients, apart from age. Kidney disease and acute kidney injury have been correlated with a higher risk of death. Notably the Italian Society of Nephrology have reported a 10-fold increase in mortality in patients undergoing dialysis compared to the rest of the population, especially during the second phase of the pandemic (26% vs 2.4). These dramatic numbers require an immediate response. At the moment of writing, three Covid-19 vaccines are being administered already , two of which, Pfizer-BioNTech and Moderna, share the same mRNA mechanism and Vaxzevria (AstraZeneca) based on a more traditional approach. All of them are completely safe and reliable. The AIFA scientific commission has suggested that the mRNA vaccines should be administered to older and more fragile patients, while the Vaxzevria (AstraZeneca) vaccine should be reserved for younger subjects above the age of 18. The near future looks bright: there are tens of other vaccines undergoing clinical and preclinical validation, whose preliminary results look promising. The high mortality of CKD and dialysis patients contracting Covid-19 should mandate top priority for their vaccination.

RESUMO

BACKGROUND: In February 2020 the corona virus disease 2019 (COVID-19) infection started spreading throughout Italy, hitting the Lombardy region very hard. Despite the high diffusion, only a subset of patients developed severe COVID-19: around 25% of them developed acute kidney injury (AKI) and one-third of them died. Elderly patients and patients with high comorbidities were identified as being at higher risk of severe COVID-19. METHODS: Our prospective observational cohort study includes 392 consecutive patients hospitalized for COVID-19 in Milan (median age 67 years, 75% male). We evaluated the relationship between blood pressure at presentation, presence of AKI at Emergency Department admission and during hospitalization, and total in-hospital mortality (24%). RESULTS: Although 58% of our study patients reported a history of hypertension (HYP) (86% on treatment), 30% presented with low blood pressure levels. Only 5.5% were diagnosed with AKI on admission; 75% of hypertensive patients discontinued therapy during hospitalization (only 20% were on treatment at discharge). Gender and hypertension were strongly associated with AKI at admission (odds ratio 11). Blood pressure was inversely correlated with increased risk of AKI upon admission, regardless of the severity of respiratory distress. Age over 65, history of hypertension, and severity of respiratory distress were the main predictors of AKI, which developed in 34.7% of cases during hospitalization. AKI was associated with increased in-hospital mortality. Hypertension and low blood pressure at presentation were the main predictors of in-hospital mortality, together with age over 65, baseline pulmonary involvement, and severity of illness. CONCLUSIONS: In patients hospitalized for COVID-19, hypertension and low blood pressure at presentation are important risk factors for AKI and mortality. Early reduction of antihypertensive therapy may improve outcomes in patients with SARS-CoV-2 infection.
