RESUMO

Introduction: Longer survival in dialysis led to a higher incidence of vascular access complications and failure. With the limited access to kidney transplantation programs and peritoneal dialysis, exhaustion of vascular access for hemodialysis is an increasingly common situation. Among the available options, atrial tunneled dialysis catheter (ATDC) has been reported as an effective vascular access in this population. Methodology. We report the experiences of two nephrology centers in Tunis with ATDC as an ultimate vascular access for dialysis. Case Reports. Two patients with exhausted vasculature underwent ATDC insertion in 2020 and 2022, respectively, as a vascular access of last resort. Both patients underwent CRBI, which resolved with favorable outcomes. One case was complicated by post-operative thrombosis and was successfully treated with thrombolysis. Both patients are currently on dialysis via their ATDC with a catheter patency of 29 months. Conclusion: ATDC is a life-saving and safe vascular access in cases of depleted vasculature. Little more than 50 cases have been reported in the literature during the last 30 years. As the frequency of vasculature exhaustion is expected to increase, preservation of veinous access in patients at risk of chronic kidney disease have never been more crucial.

RESUMO

Background: During its course, spondyloarthritis (SpA) may be associated with extra-articular manifestations affecting several organs. Renal involvement is one of the most common extra-articular manifestations and is dominated by secondary amyloidosis (AA), immunoglobulin A (IgA) nephropathy, and urolithiasis. Other nephropathies such as Focal segmental glomerulosclerosis and hyalinosis (FSGS) are less common and are limited to few case reports. Case: We report the case of a patient followed for axial SpA, who consulted, after being lost to follow-up for 3 years, for elevated blood pressure and edema of both lower limbs associated with an hydrocele and bilateral pleural effusion. Biological examinations showed hypoproteinemia, hypoalbuminemia, and proteinuria. In this context of nephrotic syndrome, the diagnosis of FSGS was confirmed by renal biopsy. Furthermore, the etiological investigation ruled out the causes of secondary FSGS. Conclusion: Renal involvement is a sign of severity in SpA. Its detection and management should be part of the overall management of SpA.

RESUMO

Introduction: hospital readmission after kidney transplantation is an important metric for health care quality, which associated with increased morbidity, costs and transition-of-care errors. It is influenced by population demographics and the comprehensiveness of the healthcare system. The aim of this study was to evaluate incidence causes and risk factors associated with hospital readmission within the first year after transplantation. Methods: all patients undergoing kidney transplantation at a single center over a ten-year period were analyzed via retrospective chart review. A multivariable logistic regression analysis was performed to identify associated factors. Results: in 86 patients, the incidence of unplanned readmissions within the first year was 68.6% (n = 59). The main reasons for HR were infection (33%), renal events (32%), surgical complications (16%), and metabolic disturbances (9%). In univariate analyses, hospital readmission was associated with Dyslipidemia p=0.04; OR=2.6; 95% CI= [1.93-13.17], anemia p=0.011; OR=4.5; 95% CI = [1.33-15.6], hemodialysis p=0,012; OR=4.8 ; 95% CI= [1.3-18.5], new onset diabetes after transplantation p=0.05 ; OR=3.5 ; 95% CI= [1.6-13,80], medical history of cardiomyopathy p=0,016 ; OR=6.4 ; 95% CI = [5.4-7.5]. While independent risk factors were: hemodialysis vintage and cardiomyopathy. There was no difference in one-year patient survival and death-censored graft survival in HR group and non-HR group. Conclusion: hospital readmissions severely affect a patient's physical and mental well-being after kidney transplantation, which is also independently associated with morbidity. Our study showed that risk factors associated with hospital readmission often reflect pretransplant comorbidity.

RESUMO

We highlight the importance of a thorough nail examination in every clinical encounter, especially in uremic patients. Absent lunula should prompt the clinician to rule out underlying kidney disease even in the absence of signs of uremia.

RESUMO

Chronic kidney disease (CKD) treated by hemodialysis (HD) is a worldwide major public health problem. Its incidence is getting higher and higher, leading to an alarming social and economic impact. The survival of these patients is significantly low, especially during the first year of treatment. The purpose of our study was to identify the epidemiological and clinico-biological characteristics of patients at the HD initiation and to reveal the predictive factors of mortality at three months and one year of HD. This is a prospective, analytical, and descriptive study dealing with 229 patients with an end-stage renal disease (ESRD), followed up in the Nephrology Department of Charles Nicolle Hospital and La Rabta Hospital in Tunisia, that was started HD between January and June 2017. A multivariate logistic regression analysis allowed us to identify the independent predictors of mortality at three months and one year. The average age was 60.2 ± 15.3 years, with a gender ratio of 1.41. Seventy-eight percent of patients had more than two comorbidities, 59% had diabetes, and 88% had hypertension. Diabetic nephropathy was the leading etiology of kidney disease (48.9%), while 11% of nephropathies were of unknown etiology. Only 58% were early referred to a nephrologist. The average glomerular filtration rate at HD initiation was 6.06 ± 2.33 mL/min/1.73 m2. Hypocalcemia and hyperphosphatemia were noted, respectively, in 60.8% and 84.9% of cases. Anemia was objectified in 98.6% of cases. HD was started in an emergency in 56.8% of cases. One of the most urgent indications was acute pulmonary edema (APE) for 43.8% of patients. Only 10.5% of patients had functional arteriovenous fistula at the dialysis initiation. Patients were hemodialyzed one, two, or three sessions per week, respectively, in 23.2%, 26.6%, and 50.2% of cases. The crude mortality rate was 25% and 13% in, respectively, one year and three months of HD. On multivariate analysis, we identified heart failure and insufficient dialysis dose per week as predictive factors of mortality at the 1st year of HD. C-reactive protein more than 21 mg/L, insufficient dialysis per week, modified Charlson Comorbidity Index less than 6, and APE at the dialysis initiation were identified as predictive factors of three-month mortality. Despite the short period of study, this work revealed the alarming conditions of patients at HD initiation. This critical situation is due to the delay in CKD diagnosis, the late nephrologist referral, and the lack of preparation before HD initiation.

RESUMO

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerular disease. The main challenge in this disease is the evaluation of prognostic factors for end-stage renal disease (ESRD). The aim of our study was to assess the clinical and prognostic implications of C4d staining in primary IgAN. This was a retrospective study, including adults with primary IgAN. The study was conducted over a period of 10 years. Renal biopsies were scored according to the Oxford classification. C4d immunohistochemical staining was performed. We included 44 patients with a sex ratio of 2.6. The average age was 35.1 ± 11 years. Twenty-two patients (57%) had hypertension (HTN). The median proteinuria was 1.92 g/day. The median of the glomerular filtration rate was 47.66 mL/min/1.73 m2. According to the Oxford classification, mesangial proliferation, endocapillary proliferation, glomerulosclerosis, interstitial fibrosis and/or tubular atrophy and crescents were present in 41%, 36%, 86%, 34%, and 25 % of cases, respectively. We found positive glomerular C4d staining in 25 renal biopsies (57%). Age at diagnosis, mean arterial pressure, HTN, and baseline glomerular filtration rate were not correlated with C4d staining. On the other hand, proteinuria was significantly higher in patients with C4d-positive renal biopsy. The median follow-up duration was 30.5 months. Ten patients (23%) reached ESRD. At univariate analysis, positive C4d staining in more than 25% of glomeruli in patients without C1q deposition in the immunofluorescent study was associated with ESRD. Our study confirms the prognostic value of C4d staining in primary IgAN.

RESUMO

Cardiovascular disease is the leading cause of death of dialyzed patients. Aortic stiffness, evaluated by the carotid-femoral pulse wave velocity (cfPWV), is now considered as a prognostic factor for cardiovascular mortality in patients with chronic kidney diseases. The peritoneal dialysis (PD) patients had significantly stiffer arteries. cfPWV was 9.12 ± 2.7 m/s in PD patients without significant correlation compared to hemodialysis (HD) patients (8.97 ± 2.52 m/s). In the univariate study, we found a statistically significant correlation between PWV and age (P = 0), between the pulse wave velocity and phosphorus (P = 0.46), between the VOP and PTH (P = 0.013) and between PWV and dyslipidemia (P = 0.014). Other variables such as phospho-calcic product, hemoglobin, total cholesterol, and KT/V were not significant. To identify the risk factors independently linked to the event, we conducted a multi-varied analysis. A correlation was found between VOP and dyslipidemia (P = 0.008). The other variables were insignificant.

RESUMO

Carotid-femoral pulse wave velocity (cf-PWV) is the noninvasive gold standard technique for measuring aortic stiffness. Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic renal disease in adults. It is associated with a high risk of cardiovascular complications. We aimed to assess the prevalence of increased arterial stiffness and its predicting factors in a population of ADPKD patients. Sixty-two patients with ADPKD underwent noninvasive measurement of cf-PWV using a COMPLIOR Analyse device. Recruitment period was 17 months and we used the cut-off of 10 m/s to define a high cf-PWV. Mean age was 51 ± 12.7 years. Gender ratio male/female was 0.63. Smoking, hypertension (HTN), and dyslipidemia were reported in 14%, 66%, and 27% of the cases, respectively. Mean glomerular filtration rate (GFR) was 47.7 ± 44 mL/min/1.73 m2. Among our patients, 39% had chronic kidney disease stages 1 or 2 and 45% stage 5 (40% stage 5D). Mean cf-PWV was 9 ± 2.4 m/s, and 31% of the patients had a high cf-PWV. In univariate analysis of all our patients, cf- PWV correlated with age (r = 0.565; P <10-3), GFR (r = -0.268;P = 0.035), C-reactive protein (r = 0.447; P = 0.007), peripheral systolic arterial pressure (r = 0.309; P = 0.015), and peripheral pulse pressure (r = 0.335; P = 0.008). Patients with high cf-PWV were on average nine years older than the others. Patients with HTN were 3.84 times more likely to have high cf-PWV (P = 0.046). cf-PWV did not seem to be lower with any antihypertensive treatment. A level of C-reactive protein higher than 10 mg/L was the only independent predicting factor of a high cf-PWV in multivariate analysis (P = 0.043). Our study confirmed the relationship between cf-PWV and age, renal failure, and HTN in patients with ADPKD. It also emphasized the close relationship between systemic inflammation and arterial stiffness in this nephropathy.

RESUMO

Epstein syndrome is characterized by sensorineural hearing impairment, macro- thrombocytopenia without neutrophil inclusion bodies, and hereditary nephritis which can progress to end-stage renal disease (ESRD) in adolescence. The prognosis of Epstein's syndrome depends on the severity of the hematological disorders and renal involvement that can lead to ESRD at an early age. Thrombocytopenia in Epstein syndrome is not an absolute contraindication for major surgical procedures like arteriovenous fistula formation or kidney transplantation. There are no set guidelines for preoperative prophylaxis in a patient with this pathology.

RESUMO

Pellagra usually results from niacin deficiency and presents with the classic triad of dermatitis, diarrhea, and dementia. It is most commonly associated with malnutrition and poverty. We report a case of pellagra in a hemodialysis (HD) patient with breast neoplasia, aged 68-years, female, on HD unit for seven years. Her original nephropathy was indeterminate. The patient was followed up for homozygous beta-thalassemia and breast neoplasia with hepatic metastases on chemotherapy. The body mass index of the patient was 18.5 kg/m2. Physical examination showed a thickening of the epidermis with a scaly surface, pigmented, and atrophied areas. We noted neuropsychiatric signs (apathy, irritability, anorexia, and depression) and digestive symptomatology (diarrhea). The laboratory tests revealed hypoproteinemia at 55 g/L, hypoalbuminemia at 21 g/L, and hypocholesterolemia at 0.8 g/L. The diagnosis of pellagra disease was made. Vitamin and protein supplementation was initiated, but the patient committed suicide by puncture of her arteriovenous fistula, causing hemorrhagic shock. Pellagra is usually reported to be associated with malnutrition, chronic alcoholism, and some chemotherapeutic agents. In our patient, pellagra was caused by malnutrition and co-morbidities. Pellagra disease requires multidisciplinary care and can be frequently seen in HD patients due to the associated malnutrition.

RESUMO

Dialysis patients have higher rates of sudden cardiac death. The study of the electrocardiogram could identify patients at risk of developing rhythm disorders. The aim of this study was to evaluate the electrocardiographic findings before and after the hemodialysis (HD) session and to examine associations of clinical and serum electrolytes with electrocardiogram findings. We conducted a multicentric transversal study, including chronic HD patients during January 2018. Standard 12-lead electrocardiogram was recorded, before and after the HD session. A medical history was documented. It included age, gender, initial nephropathy, and comorbidities. Serum potassium and total serum calcium were measured before a routine HD session. Serum potassium was measured after HD session. Corrected QT for heart rate was calculated using Bazett's formula. The study included 66 patients. Nineteen patients (28.8%) had hyperkalemia before the HD session and 44 (66.7%) patients had hypokalemia after the HD session. Seventeen patients had prolonged QTc interval (25.7%). On multiple regression analysis, only the prolonged QTc interval was significantly correlated with the serum potassium (P = 0.046).When comparing the mean values of electrocardiogram parameters before and after the HD session, we noted a significant change of heart rate (P = 0.001), R wave (P = 0.016), T wave (P = 0.001), and T/R (P = 0.001) wave. Delta K+ did not correlate with the change in T wave amplitude (r = 0.23, P = 0.59), R wave amplitude (r = -0.16, P = 0.2), T/R wave (r = 0.055, P = 0.65), or QRS duration (r = 0.023, P = 0.85). Delta QTc was correlated to ΔK+. We conclude that usual electrographic manifestations of hyperkalemia are less pronounced in HD patients. Our results confirmed the unstable status of cardiac electrophysiology during HD session.

RESUMO

Glomerulonephritis associated with anti-neutrophil cytoplasmic antibody (ANCA) vasculitis still has a high prevalence of end-stage renal disease (ESRD), particularly in patients with advanced renal failure at presentation. This study aims to evaluate the clinical and histo- pathological features of renal involvement and investigate factors associated with ESRD. Patients with renal biopsy-proven ANCA-associated glomerulonephritis were included retrospectively over a period of nine years (June 2007 to March 2016). The renal survival, defined as time to reach ESRD, was evaluated based on clinical parameters, histopathological classification, and renal risk score. A total of 37 patients with crescentic glomerulonephritis were included in the study. The average age was 54 ± 16 years (range: 17-80) and 51.3% were female. Twenty-two patients were diagnosed with microscopic polyangiitis and 15 had granulomatosis with polyangiitis. The median glomerular filtration rate at presentation was 16.73 mL/min/1.73 m2. Thirty-five patients (94.5%) had renal failure at presentation and 23 patients (62.1%) required initial hemodialysis (HD) therapy. The pattern of glomerular injury was categorized as sclerotic in 48.6% of cases, crescentic in 24.3%, mixed in 24.3%, and focal class in 2.7%. Regarding renal risk score, we had five patients with low risk, 17 with intermediate risk and 15 with high risk. ESRD occurred in 47% of intermediate-risk group and 66% of the high risk group. During follow-up, 17 patients (45.9%) developed ESRD. Tobacco addiction (P = 0.02), alveolar hemorrhage (P = 0.04), hypertension (P = 0.04), initial HD (P = 0.04), and sclerotic class (P = 0.004) were associated with ESRD. In our patients, a sclerotic class was associated with a higher risk of ESRD, suggesting that histo- pathological classification is potentially an important parameter to predict outcomes in renal disease secondary to ANCA-associated vasculitis.

RESUMO

Immunoglobulin A nephropathy is the most common primary glomerular disease. The main challenge in this disease is the evaluation of prognostic factors for end-stage renal disease. The aim of our study was to describe the characteristics of immunoglobulin A nephropathy, to evaluate the histological data according to Oxford classification, and to identify factors associated with renal survival. This was a retrospective study, including adults with primary immunoglobulin A nephropathy. The study was conducted over a period of 10 years. Renal biopsies were scored according to Oxford classification. Oxford score, based on the sum of the different histological lesions of Oxford classification, was calculated for each patient. We included 50 patients with a gender ratio (male:female) of 2.8. The average age was 35.6 ± 10.6 years. Fifty-eight percent of the patients had hypertension (HTN). The median proteinuria was 1.9 g/day. The median of the glomerular filtration rate was 47.6 mL/min/1.73 m2. According to Oxford classification, mesangial proliferation, endocapillary proliferation, glomerulosclerosis, interstitial fibrosis, and/or tubular atrophy and crescents were present in 40%, 38%, 88%, 36%, and 22% of the cases, respectively. The median Oxford score was 2. The median follow-up duration was 30 months. Ten patients (20%) reached end-stage renal disease. At univariate analysis, HTN, glomerular filtration rate, proteinuria, tubular involvement, and Oxford score >3 were associated with progression to end-stage renal disease (ESRD). Tubular involvement was an independent risk factor for ESRD. Our study confirms the prognostic value of the Oxford classification in immunoglobulin A nephropathy.

RESUMO

Thalidomide, which is an angiogenesis inhibitor and immunomodulator that reduces tumor necrosis factor-alpha, has regained value in the treatment of multiple myeloma. Serious pulmonary complications due to thalidomide use remain relatively uncommon. We describe a case of bronchiolitis obliterans organizing pneumonia (BOOP) due to thalidomide. A 51-year-old man with IgG lambda myeloma was treated with thalidomide and dexamethasone. Seven days after the beginning of chemotherapy, the patient presented a fever and a persistent cough. Auscultation revealed crackles in both pulmonary bases. The chest X-ray showed a diffuse bilateral alveolar-interstitial syndrome. Computed tomography scan revealed bilateral pulmonary involvement, with bilateral interstitial alveolar infiltration and ground-glass pattern consolidations. Pulmonary infection, malignant tumor, and lung involvement of multiple myeloma were excluded through various tests. Thalidomide-induced BOOP was suspected, and the drug was withdrawn and replaced by Melphalan. The patient had complete resolution of his symptoms and radiologic pulmonary involvement on discontinuation of the drug. In the absence of other etiologies, physicians should be cognizant of this potential complication in patients receiving thalidomide who present with respiratory symptoms.

RESUMO

BACKGROUND: Glomerular deposits are a major pathologic feature of a wide range of human glomerulonephritis and may be located in the mesangial, subepithelial, and subendothelial regions. Rare cases of primary glomerulonephritis definied by exclusive or predominant mesangial IgG deposits were reported. We reviewed the pathologic findings for the 848 renal biopsies examined in our department between 2007 and 2016, one case of primary mesangial IgG glomerulonephritis (MIG) in the absence of any evidence of systemic lupus erythematous (SLE), of other systemic diseases or of Infections. REPOTED CASE: Male patient aged 55 years consults for nephrotic syndrome (proteinuria=7g/1.73m2/day; Albuminemia=14g/L) with hematuria.. The serum creatinine concentration was 88 µmol/l, and the creatinine clearance was on MDRD at 82 ml/min/1.73m2. He had a renal biopsy showing the absence of proliferative lesions and the presence of exclusive mesangial IgG deposit. CH50, C3 and C4 levels were normal and antinuclear antibody and anti-DNA antibody assays remained negative during the follow-up period. A full dose corticosteroid was initiated (1mg/Kg/day). The interval from onset of steroid therapy to remission was 2 months. During follow-up; the patient had developed 2 relapsing nephrotic syndrome episods. Then he was switched to Mycophenolate mofetil with remission after 2 months. CONCLUSION: MIG is a very rare but distinct type of primary glomerulonephritis that is characterized by exclusive or predominant mesangial IgG deposits. Its renal prognosis may be less favorable than previously reported because of the possibility of steroids resistance of the nephrotic syndrome and the recurrence after renal transplantation.

RESUMO

The arteriovenous fistula (AVF) is the vascular access of the first choice for hemodialysis (HD). Studies on patency of AVF and its affecting factors reveal a high risk for access failure. The aim of this study was to assess the primary and secondary AVF patency and their determinant factors. It was a retrospective, descriptive study conducted in the HD facility of the Nephrology Department in Rabta University Hospital. We included AVF created before December 2009 in end-stage renal disease (ESRD) patients. The end of the follow-up was fixed in December 2013. We included 126 AVFs created in 111 patients; 22.5% were aged >65 years, 39.6% were diabetic, 68.5% were hypertensive, and 26.1% had peripheral vascular disease. The primary patency rates were 78% at one year and 42% at five years. The secondary patency rates were 80% at one year and 69% at five years. Multivariate analysis revealed that the factors affecting the primary patency of AVF were: the use of jugular catheter for longer than three months (odds ratio (OR):1.91, P = 0.044) and a C-reactive protein >5 mg/L (OR: 1.7, P = 0.049). Aging (>65 years) (OR: 2.46, P = 0.042), referral time to a nephrologist <6 months before onset of ESRD (OR: 2.87, P = 0.015), absence of an antiplatelet therapy (OR: 4.47, P = 0.005), and serum phosphorus <45 mg/L (OR: 2.07, P = 0.045) were the significant impairing risk factors for secondary AVF patency. Our study suggests that early referral and creation of AVF and maturation before ESRD as well as its adequate monitoring are essential for maintaining patency.

RESUMO

Various adverse reactions may occur after intravesical bacillus Calmette-Guérin (BCG) therapy. Although the virulence of attenuated BCG is low, serious complications such as bacterial cystitis, bladder contractures, granulomatous prostatitis, epididymitis, orchitis, and systemic reactions such as fever and malaise have been described. Disseminated granulomatosis such as hepatitis and pneumonitis have also been described, but are rare. We report here the case of a 67-year-old patient who presented with renal granulomatosis with polyangiitis following intravesical BCG therapy for superficial bladder tumor. The biological evaluation revealed the presence of perinuclear anti-neutrophil cytoplasmic antibodies with specificity for antimyeloperoxidase. Renal biopsy specimen revealed pauci-immune crescentic glomerulonephritis with segmental glomerular necrosis, presence of granulomas and no evidence of any caseating necrosis. He received antituberculosis drugs in addition to corticosteroids and cyclophosphamide without any improvement of the renal function.

RESUMO

The incidence of tuberculosis (TB) is high in patients undergoing chronic dialysis than it is in the general population. The diagnosis of TB is often difficult and extrapulmonary involvement is predominant. This study investigates the spectrum of clinical presentations and outcome in dialysis patients during a nine-year period. TB was diagnosed in 41 patients. Anti-TB drugs, adverse effects of therapy, and outcome were noted. Thirty-eight patients (92.6%) were on hemodialysis and three were on peritoneal dialysis (7.3%). The mean age at diagnosis was 50.8 years and the male/female ratio was 1.16. Four patients had a history of pulmonary TB. Extrapulmonary involvement was observed in 32 (78 %) patients. The bacteriological confirmation was made in 41.46% and histological confirmation was made in 26.83%, and in the rest, the diagnosis was retained on the criterion presumption. Nineteen patients (46.34%) developed adverse effects of antitubercular drugs. Eight patients (19.51%) died during the study from TB or adverse effects of treatment. Low urea reduction ratio and female sex were associated with poor prognosis in our study. The clinical manifestations of TB in patients on dialysis are quite nonspecific, making timely diagnosis difficult, and delaying the initiation of curative treatment, which is a major determinant of the outcome.

RESUMO

Transurethral resection of the prostate is currently the gold standard for the surgical treatment of the benign prostatic hyperplasia. This surgery may lead transurethral resection of the prostate (TURP) syndrome and in some cases, acute tubular necrosis can develop. We report a patient who developed hyponatremia, hemolysis and oliguric acute renal failure as a major complication following TURP using glycine as irrigating fluid.A 64-year-old man was admitted for a prostate resection procedure. Physical examination revealed a healthy elderly man. Preoperative laboratory data showed serum sodium 140 mEq/L, blood urea nitrogen (BUN) 0.6 g/L, creatinine 0.7 mg/dL and hemoglobin 12.9 g/dL. Few hours after, the patient becomes incoherent and developed oliguria, nausea and vomiting. The laboratory data revealed rapidly elevating BUN and creatinine levels (BUN 2.4 g/L; creatinine 6.1 mg/dL), the serum sodium concentration decreased by 14 meq/L. A decreased hemoglobin level (7.4 g/dL) with an elevated lactate dehydrogenase level (665 U/L) was observed. Renal ultrasonography was normal. The diagnosis of acute tubular necrosis complicating TURP syndrome was retained. The hyponatremia was slowly corrected to 132 mmol/L by diuresis and fluid restriction. The renal function recovered after four hemodialysis sessions. Using glycine as an irrigant for TURP may cause hyponatremia, hemolysis and also acute renal failure, especially in patients with longer resection time. It is necessary to carry out every effort to shorten resection time and avoid extravasation during surgery.
