Percutaneous Onsite Insertion of Catheter for Peritoneal Dialysis - A New Method Introduction in the Country.

Peritoneal dialysis (PD) is one of the options for renal replacement therapy (RRT) in the end stage renal disease (ESRD) patients. Compared to hemodialysis (HD), patients on PD experience a greater sense of well-being, an improved steady state in terms of extracellular fluid volume shifts and hemodynamics and it is preferred method for patients with problematic vascular access, bleeding tendencies, heart failure and elderly patients. In order to perform PD, a tunneled catheter should be placed through the abdominal wall and into peritoneal space, with positioning of the catheter within the most dependent portion of pelvis.

Glomerulopathies with Fibrillary Deposits.

The glomerulopathies associated with the deposition of extracellular fibrils in the glomeruli are subdivided into Congo red positive (amyloidosis) and Congo red negative (non-amyloidotic glomerulopathies) based on Congo red staining. The non-amyloidotic glomerulopathies are divided into immunoglobulin-derived and non-immunoglobulin-derived glomerulopathies. The immunoglobulin-derived glomerulopathies: fibrillary glomerulopathy (FGn) and immunotactoid glomerulopathy (ITG) are rare glomerulopathies.

Using a Catheter for Hemodialysis Placed in the Inferior Vena Cava for the First Time in N. Macedonia - Translumbar Approach.

Maintenance of vascular access for hemodialysis remains a challenge for every doctor. Exhausted conventional vascular access is the cause for the placement of the central venous catheter in unconventional sites such as enlarged collateral vessels, hepatic veins, hemiazygos, azygos, renal veins, and the inferior vena cava. The percutaneous translumbar catheter for hemodialysis in the inferior vena cava was described over 20 years ago.

Percutaneous Nephrostomy in the Treatment of Hydronephrosis in Renal Transplant Patients - Case Report.

Percutaneous nephrostomy is a first-line minimal invasive treatment option for ureteral obstruction following kidney transplantation, with high effectiveness and a low complication rate. Percutaneous nephrostomy might be used as a temporary salvage therapy, providing acute decompression of the kidney collecting system and preventing graft loss. It can also function as a permanent and sometimes only possible option in transplant patients with frequent recurrences of ureteral stenosis who either fail an open surgical reconstruction or who are not good candidates for these procedures.

Rhabdomyolysis Associated with Recent Infection in a Patient with Carnitine Palmitoyltransferase II Deficiency.

Carnitine palmitoyltransferase II deficiency (CPT II) is an autosomal recessive inherited disorder of long-chain fatty acid oxidation in the mitochondrial matrix, resulting in an inability to utilize fat for energy in cells. The most frequent myopathic form occurs in young adults and is associated with recurrent episodes of exercise-induced rhabdomyolysis. The myopathic form is caused by the Ser113Leu mutation of the CPT II gene.

Methods: Eighty patients with a newly created radio cephalic AVF were analyzed. Hemodynamics and morphological characteristics of the blood vessels were assessed by Doppler ultrasound.

Pharmacotherapeutic options for the prevention of kidney transplant rejection: the evidence to date.

Introduction: Although early rejection episodes are successfully controlled, the problem of unrecognized production of de novo anti-HLA antibodies and associated chronic rejection still persists.

Areas Covered: In addition to the standard induction and maintenance therapy, we present a couple of new drugs as induction (Alemtuzumab), CNI-free protocol (Belatacept, Sirolimus, and Everolimus), and maintenance treatment in transplant patients with various types of malignancies (T cell-targeted immunomodulators blocking the immune checkpoints CTLA-4 and PD1/PDL1) and TMA (aHUS)-eculizumab and IL6 receptor antagonists in antibody-mediated rejection (AMR).

Expert Opinion: There are a couple of issues still preventing improvement in kidney transplant long-term outcomes with current and anticipated future immunosuppression: patients more susceptible to infection and CNI nephrotoxicity in kidneys obtained from elderly donors and highly sensitized patients with limited chances to get appropriate kidney and a higher risk for late AMR.

COVID 19 Pneumonia and a Rare Form of Fungal Peritonitis in a Patient Survivor on Peritoneal Dialysis.

Peritoneal dialysis (PD) related peritonitis is usually caused by bacteria, but viruses and fungi could also affect the peritoneal membrane and cause cloudy effluent with negative bacterial cultures. We present a case of a PD patient who survived fungal peritonitis caused by (March 2015) and COVID-19 pneumonia (April 2021) with peritonitis probably caused by the virus. The fungal peritonitis followed one episode of exit-site infection and two episodes of bacterial peritonitis treated with a wide-spectrum antibiotic.

Urinary Proteomics in Kidney Transplantation.

Although kidney transplantation is the best treatment option for end stage kidney disease, it is still associated with long-term graft failure. One of the greater challenges for transplant professionals is the ability to identify grafts with a high risk of failure before initial decline of eGFR with irreversible graft changes. Transplantation medicine is facing an emerging need for novel disease end point-specific biomarkers, with practical application in preventive screening, early diagnostic, and improved prognostic and therapeutic utility.
