Introduction. Polycystic kidney disease is a hereditary kidney disease characterized by the occurrence of cysts (fluid-filled enlargements) in cortex or medula of the kidney, and is inherited in an autosomal dominant or autosomal recessive manner. In addition to multiple cysts in kidneys, there may be many extra-renal manifestations (cysts of the liver, pancreas, lungs, heart, etc.), among which the most serious one is intracranial aneurysms. Case report. A 57-year-old female patient with polycystic kidney disease and stage IV renal failure was hospitalized at our clinic due to decreased renal function, the development of urinary tract infections, headaches and unregulated blood pressure despite the usual treatment. This patient also had a number of associated diseases: obesity, diabetes mellitus (the insulindependent type), hypothyroidism, and depression syndrome. After better regulation of blood pressure, resolved urinary tract infections and improved renal function, there were still persistent headaches (resulting in the excessive use of analgesics). With adequate preparation, multislice computed tomography (MSCT) angiography of blood vessels of the head was performed. As a result, we diagnosed the saccular intracranial aneurysm (IA) with anterior localization. Regarding the symptoms, age and comorbidity, digital subtraction angiography (DSA) was performed, and showed saccular IA (5.2 mm ? 4 mm), with wide neck affecting both middle cerebral artery branches (MCA). During the procedure the stent was placed, which filled the aneurysm with spirals, cutting it off from circulation. After the successful procedure and without further complications, the patient no longer had headaches and blood pressure was maintained within the required limits with stable parameters of chronic renal failure. Conclusion. The case of the patient with polycystic kidney disease, stage IV chronic renal failure, with a number of comorbidities (headache, obesity, hypertension, diabetes mellitus, hypothyroidism) and diagnosed with symptomatic intracranial aneurysm was successfully solved with a multidisciplinary approach, emphasizing the importance of teamwork in daily practice.

Renal Complication

Abstract Background: Autosomal dominant polycystic kidney disease (ADPKD) is a renal inherited disease characterized by the growth of bilateral renal cysts that lead to deterioration in renal function and end-stage renal disease (ESRD). These patients frequently present complications like urinary tract infection, acute pyelonephritis, acute or chronic pain, renal lithiasis or high blood pressure (HBP). The aim of this study is to compare the renal evolution in ADPKD patients with renal complications and/or HBP compared to those without complications nor HBP.Methods: Observational retrospective study of 29 ADPKD patients with normal renal function and <70 years followed up in our center. Clinical and analytical information of 2010, 2015 and 2017 were determined.Results: 29 patients were enrolled with a median age of 41 years [34-54], eighteen women (62,1%) and eleven men. Median of estimation of glomerular function rate (eGFR) was 85.8ml/min [70.7-115.6] in 2010, 76.0 ml/min [57.0-99.9] in 2015 and 63.1ml/min [45.0-95.8] in 2017. Eight patients (27.6%) have never had kidney complication nor HBP. Nine patients (31.0%) have normal blood pressure, 6 others (20.7%) have well controlled high blood pressure (HBP) and 14 (48.3%) have badly controlled HBP. When patients were divided between those who have never presented a complication (C-) and those who present renal complication and/or HBP (C+), the first group presented better kidney function. When patients were segregated into those who have never presented complication or well-controlled HBP (CHBP-) and those with renal complication and/or badly-controlled HBP (CHBP+) no differences were found at the initial eGFR, but a faster worsening of kidney function in CHBP+ group.Conclusions: In ADPKD patients, the decrease in eGFR is significantly important in individuals showing complications (including HBP) compared to those who did not present complications. Individuals with complications and badly-controlled HBP show even greater differences in kidney function decrease compared with patients without complications or well controlled HBP.

Urinary Citrate

Abstract Background and Aims In polycystic kidney disease (PKD) it is frequently found a reduction in urinary citrate that is related with degree of renal impairment but it is unknown if this alteration is specific or if it is also present in other nephropathies. Recently it has been suggested that urinary citrate could be a marker of covert metabolic acidosis and reflects acid retention in chronic kidney disease (CKD). Our aim was to compare urinary citrate in PKD with other renal diseases and to show its relation with serum bicarbonate and excretion of uric acid and calcium. Method We determined citrate, calcium and uric acid in 24-hour urine in patients with PKD and with other nephropathies with varied degree of renal impairment followed in a outpatient clinic of nephrology. Results We included 291 patients, 119 with glomerular diseases, 116 with PKD, 21 with other nephropathies, and 35 patients with normal renal function. Urinary citrate was higher in women (Females 309±251 mg/gCr vs. males 181±145 mg/gCr, p&lt;0.001) and in patients with normal renal function (normal 380±210 mg/gCr; PKD 203±166 mg/gCr; glomerular 279±282 mg/gCr; p&lt;0,001). PKD patients showed similar values of urinary citrate to patients with glomerular diseases and with other nephropathies. We observed a progressive reduction in urinary citrate parallel to degree of renal impairment, in a comparable way among patients with PKD and glomerular diseases. We did not observe a relationship between urinary citrate and serum bicarbonate levels. Calcium and uric acid elimination in ADPKD patients was similar to other nephropathies and lower to patients with normal renal function. However, serum uric acid was significantly higher in glomerular patients than other nephropathies after adjust with glomerular filtration rate and sex. Conclusion Hypocitraturia is not specific of PKD but it is also present in all nephropathies. Urinary citrate are related to degree of renal impairment and it is not related with serum bicarbonate. We think that it could be interesting to study urinary citrate as a marker of renal function and its role as prognostic factor of renal deterioration.
