Background: Lupus nephritis (LN) is one of the most severe manifestations of systemic lupus erythematosus (SLE). There are increased studies examining the role of different markers that would facilitate diagnosis, LN activity monitoring, relapse occurrence, and the right time to introduce maintenance therapy. We aimed to examine the importance of determining the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), systemic immuneinflammatory index (SII) and systemic inflammatory response index (SIRI) in LN, comparing their significance with other standard parameters of active disease. Methods: The clinical examination included 66 patients (34 with active and 32 with LN in remission) and 23 healthy controls. The investigated parameters were CRP, CBC, creatinine, albumin, GFR, C3, C4, ANA, anti-ds DNA Ab, in urine: sediment analysis, SLEDAI/r, proteinuria 24h and Up/cre. We determined the derived markers: NLR, PLR, SIRI, and SII and their correlation with other parameters of active disease. Results: Comparing the group with active LN with LN in remission and the control group, a statistically significant difference was obtained for CRP (p=0.004) and RBW and haemoglobin, albumin, C3, ANA and anti-ds DNA Ab (p

Background: Metabolic syndrome (MetS) in patients with systemic lupus erythematosus (SLE) represents an additional burden and a poor prognostic factor for the onset or worsening of atherosclerosis and cardiovascular complications. In many patients with lupus nephritis (LN), MetS is often already manifested initially. Our work aimed to determine the frequency and characteristics of MetS in patients with LN, as well as the relationship components of MetS and characteristics of disease activity. Methods: The clinical study included 67 patients with LN, 54 (80.59%) female and 13 (19.41%) male, with an average age of 42.86±14.46 years. Patients were divided into two groups: with MetS (35.82%) and without MetS (64.18%), active LN had (34 or 50.74%), and LN in remission (33 or 49.25%). We monitored clinical and biochemical parameters of interest. Results: Comparing patients with LN collectively, as well as those with MetS and without MetS, we observed that patients with MetS were older (p=0.001), BMI (p

Background/Aim. Lupus nephritis (LN), as an immuno-inflammatory kidney lesion and the most severe manifestation of systemic lupus erythematosus (SLE), is accompanied by a disorder of nutritional status of patients. The aim of our study was to determine the importance of parameters of nutritional status [nutritional risk index (NRI), prognostic nutritional index (PNI), and Controlling Nutritional Status (CONUT)] and their association with standard parameters of LN activity. Methods. The clinical study included a group of 92 participants: 67 patients with LN (34 patients had LN active disease – the LNa group, and 33 patients were in LN remission – the LNr group) and 25 healthy subjects in the control group. In addition to standard laboratory parameters and LN activity parameters, derived parameters were also determined: PNI = 10 × serum albumin value (g/dL) + 0.005 × total lymphocyte count/mm3; N RI = 1 .519 × serum albumin value (g/dL) + 41.7 × present weight (kg)/usual body weight (defined as stable body weight for last six months) (kg); CONUT score = serum albumin value (g/dL) + total lymphocyte count/mm3 + total cholesterol level (mmol/L). Results. A statistically significant difference between all three groups was observed for the PNI (p = 0.001) and the CONUT score (p = 0.000), while there was no significant difference for NRI. In the LNa group, a statistically significant correlation was found for PNI in relation to albumin, complement C 3 and C 4, and a statistically significant negative correlation with the level of anti-double stranded (ds) DNA antibodies (Abs). NRI had a statistically significant correlation only with proteinuria in the LNa group. CONUT showed significant correlations with most of the parameters of disease activity: negative correlation with albumin and complement C3 (p = 0.000), and positive correlation with anti-dsDNA Abs (p = 0.002), Systemic Lupus Erythematosus Disease Activity Index/renal (SLEDAI/r), and proteinuria g/24 hrs (p = 0.000). Conclusion. A statistically significant difference was observed between the groups for the nutrition score CONUT and the PNI. Their correlation with standard parameters of active disease was significant for most parameters in the group of patients with LNa.

Background/Aim. Inflammation is the main cause of the onset, progression, and outcome of chronic kidney disease (CKD). The aim of the study was to examine the predictive value of inflammatory biomarkers in patients with CKD stages I–V and their association with parameters characteristic of CKD. Methods. A cross-sectional study analyzed 117 adult patients with CKD who were divided into two groups according to the glomerular filtration rate (GFR): Group 1, with normal to mild impairment of renal function (GFR ≥ 60 mL/min/1.73 m2), stages I and II, and Group 2 with moderate and severe impairment of renal function (GFR < 60 mL/min/1.73 m2), stages III, IV, and V, who have not started dialysis treatment. In addition to standard laboratory analyses, we determined derived parameters in patients, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and system inflammation response index (SIRI), as markers of inflammation. Results. A statistically significant difference between Groups 1 and 2 was observed for body mass index (p < 0.003), for platelets, hemoglobin, creatinine, urea, acidum uricum, iron, phosphorus, parathyroid hormone, and proteinuria 24 hrs (p < 0.001), for calcium (p < 0.031) and leukocytes (p < 0.030). By analyzing the values of NLR, PLR, SII, and SIRI in patients with CKD, a statistically significant difference (p < 0.001) was observed between the groups; the values were elevated in Group 2. NLR, PLR, and SII showed statistical significance for essential parameters in CKD (C-reactive protein, creatinine, GFR, hemoglobin, calcium, phosphorus, parathyroid hormone) and SIRI showed statistical significance for phosphorus in Group 2. The most sensitive was NLR at 87.7%, and PLR had the highest specificity, at 81.7%, with cut-off values for PLR – 151.75, NLR – 2.06, SII – 493.57, and SIRI – 0.739. Conclusion. Our results indicate that the detection of biomarkers NLR, PLR, SII, and SIRI could have a significant role in predicting inflammation in patients with CKD and would contribute to the timely recognition of patients at risk of developing complications.

Background: Lupus nephritis (LN) is one of the most serious complications in the development of systemic lupus erythematosus, that can adversely affect the course and prognosis of this autoimmune disease. Therefore, monitoring the effect of applied therapy, achieving remission, or monitoring class IV LN activity is still a great challenge for nephrologists. This study aimed to compare the urinary neutrophile gelatinase associated lipocalin (u/NGAL) with traditionally accepted parameters for LNactivity to indicate the importance of its determination in these patients. Methods: The study group consisted of 40 patients with class IV LN, who were prospectively followed for a period of 4 months within three control visits to 2 months. The first group (20/40) had active disease (Group A), and the second group had diseasein remission (Group B). The parameters we monitored and compared at each visit were standard biochemical parameters and kidney function parameters: C-reactive protein (CRP), blood count (CBC), creatinine, total proteins, albumin, cholesterol, triglycerides, glomerular filtration rate (eGFR). Regarding immune parameters, complement C3 and C4, antinuclear antibodies (ANA), anti-double stranded DNA antibody(anti ds DNA Ab) were monitored. Urine sediment, proteinuria 24h, urine culture, urinary protein/creatinine ratio - Up/Cre, and urinary NGAL (u/NGAL) were monitored in Results: Comparing standard parameters of disease activity and u/NGAL between groups, a statistically significant difference was obtained (p < 0.001). Within Group A, comparing the parameters by visits (0 : 2) for anti-ds-DNA Ab a significance of p< 0.05 was obtained, for albumin/s and C3 a significance of p

Background/Aim. Contrast-induced acute kidney injury (CI-AKI) is a common complication after the percutaneous coronary intervention, associated with a prolonged hospital stay, increased medical costs, and risk of adverse clinical outcomes. The aim of this study was to compare changes in levels of serum creatinine (sCr) and cystatin C (sCyC) 24 h after coronary angiography as an early indicator of CI-AKI. Methods. The study included 45 patients with chronic renal failure grade I–III scheduled for coronary angiography. Levels of sCr and sCyC were measured a day before and 24 h after coronary angiography. CI-AKI was defined as a 25% and 10% increase of sCr and sCyC levels from baseline within 24 h from contrast media exposure, in the absence of alternative causes. Results. Mean sCr and sCyC concentra-tions were 86.4 ± 22.6 μmol/L and 1.18 ± 0.52 mg/dL, respectively before contrast administration, and 90.6 ± 24.1 μmol/L and 1.24 ± 0.65 mg/dL, respectively 24 h after contrast media exposure. sCr-based CI-AKI occurred in 4 patients (8.89%) and sCyC-based CI-AKI was detected in 19 patients (42.22%) after the contrast procedure (p < 0.001). Conclusion. sCyC level measured 24 h after contrast media exposure is a more sensitive indicator of CI-AKI than sCR level.

Introduction. Kidney failure in multiple myeloma is some-times initial symptomatology and a very serious complication with an unfavorable effect on the course and prognosis of the disease. Multiple myeloma is a disease characterized by the proliferation of plasmocytes in the bone marrow, and in rare cases, it can be extramedullary in various organs and systems. Pulmonary plasmacytoma localization is a rare extramedullary localization, especially when it represents one of the initial manifestations of multiple myeloma. Case report. We present a patient with progressive acute kidney failure who has started hemodialysis treatment. On chest radiography, a homogeneous shadow was observed along the left chest wall, and the multislice computed tomography (MSCT) pointed to the tumor formation in the pulmonary parenchyma in the projection of the left upper pulmonary lobe with signs of pleural infiltration, intercostal muscles, and V rib destruction. Laboratory examination indicated the presence of Bence-Jones proteinuria in the urine sample in addition to anemia syndrome and azotemia with hyperuricemia. After bronchoscopy and needle biopsy, diffuse infiltration of mature plasma cells was demonstrated in the cytological and histopathological findings of the lungs. The histopathological finding of bone marrow biopsy indicated multiple myeloma of Lambda type with infiltration of plasma cells – about 70%. The hematologist determined a diagnosis of multiple myeloma BJ lambda III BCS, with extramedullary lung infiltration and acute kidney failure. Further treatment was continued according to the hematological protocol while performing intermittent hemodialysis. Conclusion. Sometimes, extremely rarely, and in completely asymptomatic patients with massive pulmonary infiltration observed initially, the differential diagnosis may also represent an extramedullary presentation of multiple myeloma, which should be considered.

Background/Aim. Vitamin D insufficiency/deficiency is often present in patients with type-2 diabetes mellitus (DM) and could present a risk factor for rapid progression of diabetic nephropathy and for higher incidence of cardiovascular events. The aim of this study was to examine the influence of vitamin D supplementation on proteinuria, cholesterol, triglycerides, C-reactive protein (CRP) and hemoglobin A1c in patients with type-2 DM and vitamin D insufficiency/ deficiency. Methods. This prospective, cohort study included 90 patients with type-2 DM and vitamin D insufficiency/ deficiency divided into 3 equal groups: with normal proteinura, with microproteinuria and with macroproteinuria. Therapy included six months of supplementation with cholecalciferol drops: first two months with 20,000 IU twice weekly, than if level of vitamin D was below normal the same dose was given next four months. If the level of vitamin D was normal 5,000 IU was given twice weekly. At the begining and at the end of the study the levels of urea, creatinine, fasting blood glucose, calcium, phosphorus, cholesterol, triglycerides, CRP, hemoglobin A1c, intact parathyroid hormone, 24-hour urine protein and creatinine clearance were determined. Levels of calcium, phosphorus and vitamin D were also checked 2 months after beginning of therapy due to possible correction of cholecalciferol dose. Results. The lowest level of vitamin D before therapy was found in patients with macroproteinuria, while at the end of the study the significantly higher level of vitamin D was found in all three groups. After 6 months of therapy a significant decrease of 24-hour urine protein, cholesterol, triglycerides, hemoglobin A1c in all three groups, and CRP in patients with normal proteinuria and microproteinuria were found. Significantly negative correlation between vitamin D and 24-hour urine protein, cholesterol and CRP was found in patients with macroproteinuria. Also, significantly negative correlation was found between vitamin D and hemoglobin A1c, in patients with normal proteinuria, vitamin D and CRP in patients with microproteinuria. Conclusion. A preventive use of high-dose cholecalciferol supplementation in patients with type-2 DM (with or without proteinuria) decreases cholesterol, triglycerides, proteinuria, CRP and hemoglobin A1c.

Background/Aim. Hyperbaric oxygen therapy (HBOT) is a method which increases oxygen solubility in plasma up to 20 times. This effect is very important in the treatment of circulatory disorders, which reduces oxygenation and leads to increased production of inflammatory mediators and free oxygen radicals. The aim of this study was to examine the impact of HBOT on the oxidative stress parameters in the patients with systemic lupus erythematosus (SLE). Methods. This prospective study included 18 females with SLE [American College of Rheumatology (ACR) criteria], average age 52.2 ± 8.82 years, treated with HBOT for 60 min/day, with average partial oxygen pressure of 2.2 atmospheres absolute (ATA), during 10 days, in combination with appropriate medication therapy for SLE. The following parameters were determined in the serum: C-reactive protein (CRP), hemoglobin, creatinine, albumin, complement 3 (C3), antinuclear antibodies (ANA), glomerular filtration rate (GFR) using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. In the urine, parameters of oxidative stress were spectrofotometrically determined: levels of superoxide anion radical (O2 •–), hydrogen peroxide (H2O2), nitrites (NO2-) and concentration of thiobarbituric acid reactive substances (TBARS). In hemolysate, the parameters of antioxidant protection: superoxide dismutase (SOD), catalase (CAT) and reduced gluthatione (GSH), were measured. The samples for the analysis were collected three times: before HBOT (initial values), after 10 days of HBOT and 1 month after beginning the treatment in relation to the initial value. Results. We noticed a statistically significant (p < 0.05) decrease in a level of O2 •–, both after 10 days and after 1 month of HBOT (8.26 ± 13.62; 8.39 ± 4.94; 11.92 ± 6.86 nmol/mL, respectively). Values of other parameters of oxidative stress such as NO2-, TBARS and H2O2- showed no significant difference during the monitored period. Regarding the parameters of antioxidant the protection, we revealed slightly higher value of GSH after treatment (initial value: 66.34 ± 16.31; after 10 days of HBOT 79.43 ± 36.77; after 1 month of HBOT69.72 ± 22.32 μmol/mL red blood cells) which was held after a month, but it was not statistically significant. Activity of SOD and CAT, before and after HBOT, did not change significantly. Conclusion. Our results suggested the potential beneficial effects of HBOT on redox status in the patients with SLE by decreasing the levels of O2•–.

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.

Background/Aim. Patients with chronic renal failure (CRF) have increased cardiovascular morbidity and mortality. It is unknown which biomarkers best describe the degree of diastolic dysfunction in patients with CRF. The aim of this study was to determine the correlation between B-type natriuretic peptide (BNP), N-terminal prohormone brain natriuretic peptide (NTproBNP) and left ventricular diastolic dysfunction (DD-LV) with the degree of CRF. Methods. The study included 100 adult patients with CRF without major cardiac and cerebral incidents who did not start actively treating CRF. According to the degree of CRF, the patients were divided into two groups: G1 (moderate degree), glomerular filtration rate (GFR) ≥ 30 mL/min/1.73 m2, and G2 (more severe degree), GFR < 30 mL/min/1.73 m2. Blood concentrations of BNP and NTproBNP were measured and Doppler echocardiographic measurement performed to estimate diastolic dysfunction (DD-LV). According to the degree of DD-LV, all the patients were divided into two groups: DD-LV1 (mild diastolic dysfunction) and DD-LV2 (severe diastolic dysfunction). According to the degree of CRF and DD-LV, the patients were divided into four groups: I (G1, DD-LV1), II (G1, DD-LV2), III (G2, DD-LV1) and IV (G2, DD-LV2). Results. There was a highly significant statistical correlation between BNP and NTproBNP with GFR (p < 0.001), and DD-LV with BNP (p < 0.023) and NTproBNP (p = 0.035). In patients with DD-LV2, a statistically significantly higher BNP concentrations were registered in patients with G2 (p < 0.001). Unlike BNP in the patients with diastolic dysfunction DD-LV1 and those with diastolic dysfunction DD-LV2, significantly higher concentrations of NTproBNP were registered in the patients with G2 (DD- LV1: p = 0.006; DD-LV2: p < 0.001). Conclusion. Biomarkers BNP and NTproBNP are not the best predictors in the assessment of diastolic dysfunction because they are correlated with the degree of renal insufficiency.

Introduction. Situs inversus totalis (SIT) represents a total vertical transposition of the thoracic and abdominal organs which are arranged in a mirror image reversal of the normal positioning 1. We presented a successful pre-dialysis kidney transplantation from a living sibling donor with SIT and the longest donor follow-up period, along with analysis of the reviewed literature. Case report. The pair for pre-dialysis kidney transplantation included a 68-year-old mother and 34-year-old daughter at low immunological risk. Comorbidities evidenced in kidney donors with previously diagnosed SIT, included moderate arterial hypertension and borderline blood glucose level. Explantation of the left donor kidney and its placement into the right iliac fossa of the recipient were performed in the course of the surgical procedure. A month after nephrectomy, second degree renal failure was noticed in the donor. A 20-month follow-up of the donor’s kidney and graft in the recipient proved that their functions were excellent. Conclusion. In donors with previously diagnosed SIT the multidisciplinary approach, preoperative evaluation of the patient and detection of possible vascular anomalies are required to provide maximum safety for the donor.

Introduction. Oxygen is an essential element of life in aerobic organisms. However, if not controlled, inhalation of oxygen under increased pressure in conditions of hyperbaric oxygen therapy can lead to serious damage and even death. Case report. We presented a 20-year-old male who had begun exhibiting symptoms of epilepsy during diving test in a hyperbaric chamber while inhaling 100% oxygen. He was immediately taken off oxygen mask and started breathing air and began rapid decompression. He lost consciousness, began foaming at the mouth, and had a series of tonic spasms. The patient was previously completely healthy and not on any medications. He was admitted for emergency treatment in our hospital, where he was treated for epilepsy. On admission, he complained of muscle and joint pain, and had erythematous changes on the forehead, neck and chest. All these changes occurred after leaving the hyperbaric chamber. Bloodwork revealed leukocytosis with neutrophil (Leukocytosis 16.0 ´ 109/L (reference values 4.00-11.00 ´ 109/L), Neutrophili 13 ´ 109/L (reference values 1.9-8.0 ´ 109/L), with elevated enzymes aspartate aminotransferase (AST) 56 U/L (reference values 0-37 U/L), alanin aminotransferase (ALT) 59 U /L, (reference values 25-65 U/L), creatine kinase (CK) 649 U/L, (reference values 32-300 U /L), lactate dehydrogenase (LDH) 398 U/L (reference values 85- 227 U/L). Because of pain and his condition we began treatment in a hyperbaric chamber at a pressure of 2.0 ATA for 70 minutes, resulting in a reduction of symptoms and objective recovery of the patient. Within 24 h, repeated laboratory tests showed a reduction of leukocytosis (13 ´ 109/L and neutrophils (7.81 ´ 109/L), and the gradual reduction of the enzymes AST (47 U/L), ALT (50 U/L, CK (409 U/L), LDH (325 U/L). Since head CT and EEG were normal, epilepsy diagnosis was ruled out. This fact, along with medical tests, facilitated the differential diagnosis and confirmed that this was a case of neurotoxic effects of oxygen while the patient was in a hyperbaric chamber, not epileptic seizures. Conclusion. This case report suggests that in patients with symptoms of epileptic seizures while undergoing treatment in a hyperbaric chamber, it is always important to think of neurotoxic effects of pure oxygen which occurs at higher pressures and with a longer inhalation of 100% oxygen. In these patients, reexposure to hyperbaric conditions leads to recovery. This effect is important in daily inhalation of 100% oxygen under hyperbaric conditions which is why the use of pure oxygen is controlled and diving is allowed in shallow depths and for a limited time.

Introduction. Immunoglobulin D (IgD) myeloma is a rare disease, about 2% of all myelomas, even rarer when accompanied with another multiple myeloma in biclonal gammopathy. We presented a case of biclonal gammopathy - associated manifestation of IgD myeloma and light chain disease in a patient who initially had renal failure. Case report. 37-year-old male approximately one month before hospitalization began to feel malaise and fatigue along with decreased urination. Laboratory analysis revealed azotemia. A dialysis catheter was placed and hemodialysis started. The patient was then admitted to our hospital for further tests and during admission, objective examination revealed pronounced paleness with hepatosplenomegaly and hypertension (170/95 mmHg). Laboratory analysis showed erythrocyte sedimentation rate 122 mm/h, expressed anemic syndrome (Hb 71 g/L) and renal failure dialysis rank: creatinine 1,408 μmol/L, urea31.7 mmol/L. There was two M components in serum protein electrophoresis: IgD lambda and free light chain lambda. Proteinuria was nephrotic rank (5.4 g/24 h), whose electrophoresis revealed 2 M components - massive in α 2 fraction of 71%; 7% in the discrete β fraction, beta 2M /serum 110 mg/L, in urine 1.8 mg/L - extremely high; IgL kappa / lambda index 1 : 13 (reference value ratio 2 : 1). The findings pointed to double myeloma disease: IgD myeloma and Bence Jones lambda myeloma. Bone biopsy confirmed IgD myeloma lambda 100% infiltration medulla predominantly plasmablasts. The treatment continued with hemodialysis 3 times per week with chemotherapy protocol bortezomib, doxorubicin, dexamethasone. After 4 cycles of chemotherapy, there was a decrease of IgD, λ - light chains, reduction in proteinuria (1.03 g/24 h), so hemodialysis was reduced to once per week. Six months after treatment initiation the patient underwent autologous bone marrow transplantation. In a 2-year follow-up period double myeloma disease showed complete remission. Conclusion. The presented rare form of double myeloma disease with initial renal insufficiency underscores the importance of careful observation and team-work that can alter the course of this serious disease.

Background/Aim. Tremendous breakthrough in solid organ transplantation was made with the introduction of calcineurin inhibitors (CNI). At the same time, they are potentially nephrotoxic drugs with influence on onset and progression of renal graft failure. The aim of this study was to evaluate the outcome of a conversion from CNIbased immunosuppressive protocol to sirolimus (SRL) in recipients with graft in chronic kidney disease (CKD) grade III and proteinuria below 500 mg/day. Methods. In the period 2003-2011 24 patients (6 famale and 18 male), mean age 41 ± 12.2 years, on triple immunosuppressive therapy: steroids, antiproliferative drug [mycophenolate mofetil (MMF) or azathiopirine (AZA)] and CNI were switched from CNI to SRL and followe-up for 76 ± 13 months. Nine patients (the group I) had early postransplant conversion after 4 ± 3 months and 15 patients (the group II) late conversion after 46 ± 29 months. During the regular outpatient controls we followed graft function through the serum creatinine and glomerular filtration rate (GFR), proteinuria, lipidemia and side effects. Results. Thirty days after conversion, in all the patients GFR, proteinuria and lipidemia were insignificantly increased. In the first two post-conversion months all the patients had at least one urinary or respiratory infection, and 10 patients reactivated cytomegalovirus (CMV) infection or disease, and they were successfully treated with standard therapy. After 21 ± 11 months 15 patients from both groups discontinued SRL therapy due to reconversion to CNI (10 patients) and double immunosuppressive therapy (3 patients), return to hemodialysis (1 patient) and death (1 patient). Nine patients were still on SRL therapy. By the end of the follow-up they significantly improved GFR (from 53.2 ± 12.7 to 69 ± 15 mL/min), while the increase in proteinuria (from 265 ± 239 to 530.6 ± 416.7 mg/day) and lipidemia (cholesterol from 4.71 ± 0.98 to 5.61 ± 1.6 mmol/L and triglycerides from 2.04 ± 1.18 to 2.1 ± 0.72 mmol/L) were not significant. They were stable during the whole follow-up period. Ten patients were reconverted from SRL to CNI due to the abrupt increase of proteinuria (from 298 ± 232 to 1639 ± 1641/mg day in 7 patients), rapid growth of multiple ovarian cysts (2 patients) and operative treatment of persisted hematoma (1 patient). Thirty days after reconversion they were stable with an insignificant decrease in GFR (from 56.10 ± 28.09 to 47 ± 21 mL/min) and significantly improved proteinuria (from 1639 ± 1641 to 529 ± 688 mg/day). By the end of the follow-up these patients showed nonsignificant increase in the serum creatinine (from 172 ± 88 to 202 ± 91 mmol/L), decrease in GFR (from 56.10 ± 28.09 to 47 ± 21 mL/day) and increased proteinuria (from 528.9 ± 688 to 850 ± 1083 mg/min). Conclusion. In this small descriptive study, conversion from CNI to SRL was followed by an increased incidence of infections and consecutive 25-50% dose reduction in the second antiproliferative agent (AZA, MMF), with a possible influence on the development of glomerulopathy in some patients, which was the major reason for discontinuation of SRL therapy in the 7 (29%) patients. Nine (37.5%) of the patients experienced the greatest benefit of CIN to SRL conversion without serious post-conversion complications.

Background. Systemic lupus erithematodes (SLE) is chronic, often febrile, multisystemic disease unknown origin and relapsing course which affects connective tissue of the skin, joints, kidney and serous membranes. Gastrointestinal manifestations are rarely the first sign of systemic lupus erythematosus. Case report. We presented a female patient, 35 years old, whose first symptoms of SLE were paralitic ileus (chronic intestinal pseudo-obstruction) and polyserositis (pleural effusion and ascites). Except for high parameters of inflammation, leucopenia and thrombocytopenia, all immunological and laboratory tests for SLE were negative in the onset of the disease. During next six months the patient had clinical signs of paralitic ileus several times and was twice operated with progressive malabsorptive syndrome. The full picture of SLE was manifested seven months later associated with lupus nephritis. Treatment with cyclophosphamide, corticosteroids and total parenteral nutrition (30 days) induced stable remission of the disease. Conclusion. The SLE can be initially manifested with gastroenterological symptoms without any other clinical and immunologic parameters of the disease. If in patients with SLE and gastrointestinal tract involvement malabsorption syndrom is developed, a treatment success depends on both immunosupressive therapy and total parenteral nutrition.

Background/Aim. Due to improved methods for removal of ABO isoagglutinins and novel immunosuppressive protocols, short and long term outcome in blood group incompatible is similar to blood group compatible kidney transplantation. The aim of this study was to determine the efficacy of our original method for removal of ABO isoagglutinins from the blood in ABO-incompatible kidney allograft recipients. Method. Between 2006 and 2008 twelve patients were transplanted from ABO incompatible living donors. Titers of ABO isoagglutinins were 4-128 (IgG). Immunosuppressive therapy started 14 days before kidney transplantation with rituximab, followed by a triple therapy (prednisone + tacrolimus + mycophenolate mofetil) and the first plasma exchange (PE) procedure, in which one plasma volume was substituted with albumin and saline on day 7 before transplantation. For selective extracorporeal immunoadsorption, the removed plasma was mixed with donor blood type filtered red blood cells, centrifuged and the supernatant separated and preserved. In the next PE procedure, the removed plasma was replaced with immunoadsorbed plasma, and so on. Titers of ABO agglutinins, renal allograft function and survival were followed-up. Results. The pre-transplant treatment consisting of 1-5 PE procedures and immunosuppressive therapy resulted in target ABO agglutinins titers below 4. During a 10-24 month follow-up three patients had an early acute rejection, one patient acute rejection and hemolytic anemia, two patients surgical complications and one of them lost his graft. In the post-transplant period, the titers of ABO antibodies remained below 4. All the patients had stable kidney allograft function with mean serum creatinine ±SD of 129 ± 45 μmol/l at the end of the study. Conclusion. Our method for removal of ABO antibodies was effective in a limited series of patients and short-term follow-up.

Background. Multiple myeloma is a plasmaproliferative disease characterized by the uncontrolled proliferation of a pathogenic plasma cell clone engaged in the production of monoclonal immunoglobulin. This condition affects the bone marrow, but it can be manifested in any other organ or tissue. The urinary bladder involvement is extremely rare. Case report. We reported a 70-year-old male with the history of multiple myeloma, receiving chemotherapy containing melphalan and prednisone (MP). Two years after the treatment, there was a renal failure associated with oligoanuria, hematuria and bilateral hydronephrosis. The urine cytology tests revealed the atypical cells, so was suspected obstructive uropathy to be caused by urothelium cancer. However, only upon the cystoscopy and biopsy performed on the urinary bladder mass, plasmacytoid infiltration diagnosis was confirmed. This extremely rare variant was presented throughout the illness period and proved to be resistant to the administered chemotherapy. Conclusion. When renal failure associated with hematuria and bilateral hydronephrosis is presented in a patient with multiple myeloma, this unusual and rare extramedular localization should be also considered.

Background. Systemic lupus erithematodes (SLE) is chronic, often febrile, multisystemic disease unknown origin and relapsing course which affects connective tissue of the skin, joints, kidney and serous membranes. Gastrointestinal manifestations are rarely the first sign of systemic lupus erythematosus. Case report. We presented a female patient, 35 years old, whose first symptoms of SLE were paralitic ileus (chronic intestinal pseudo-obstruction) and polyserositis (pleural effusion and ascites). Except for high parameters of inflammation, leucopenia and thrombocytopenia, all immunological and laboratory tests for SLE were negative in the onset of the disease. During next six months the patient had clinical signs of paralitic ileus several times and was twice operated with progressive malabsorptive syndrome. The full picture of SLE was manifested seven months later associated with lupus nephritis. Treatment with cyclophosphamide, corticosteroids and total parenteral nutrition (30 days) induced stable remission of the disease. Conclusion. The SLE can be initially manifested with gastroenterological symptoms without any other clinical and immunologic parameters of the disease. If in patients with SLE and gastrointestinal tract involvement malabsorption syndrom is developed, a treatment success depends on both immunosupressive therapy and total parenteral nutrition.

Background. Multiple myeloma is a plasmaproliferative disease characterized by the uncontrolled proliferation of a pathogenic plasma cell clone engaged in the production of monoclonal immunoglobulin. This condition affects the bone marrow, but it can be manifested in any other organ or tissue. The urinary bladder involvement is extremely rare. Case report. We reported a 70-year-old male with the history of multiple myeloma, receiving chemotherapy containing melphalan and prednisone (MP). Two years after the treatment, there was a renal failure associated with oligoanuria, hematuria and bilateral hydronephrosis. The urine cytology tests revealed the atypical cells, so was suspected obstructive uropathy to be caused by urothelium cancer. However, only upon the cystoscopy and biopsy performed on the urinary bladder mass, plasmacytoid infiltration diagnosis was confirmed. This extremely rare variant was presented throughout the illness period and proved to be resistant to the administered chemotherapy. Conclusion. When renal failure associated with hematuria and bilateral hydronephrosis is presented in a patient with multiple myeloma, this unusual and rare extramedular localization should be also considered.

Background: In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors., Method: We retrospectively identified 14 patients who received renal allograft from spousal donors between 1996 and 2009 (group I). The control group consisted of 14 patients who got graft from related donor retrieved from the database and matched than with respect to sex, age, kidney disease, immunological and viral pretransplant status, the initial method of the end stage renal disease treatment and ABO compatibility. In the follow-up period of 41 +/- 38 months we recorded immunosuppressive therapy, surgical complications, episodes of acute rejection, CMV infection and graft function, assessed by serum creatinine levels at the beginning and in the end of the follow-up period. All patients had pretransplant negative cross-match. In ABO incompatible patients pretransplant isoagglutinine titer was zero., Results: The patients with a spousal donor had worse HLA matching. There were no significant differences between the groups in surgical, infective, immunological complications and graft function. Two patients from the group I returned to hemodialysis after 82 and 22 months due to serious comorbidities., Conclusion: In spite of the worse HLA matching, graft survival and function of renal grafts from spousal donors were as good as those retrieved from related donors.

Introduction: Kidney transplantation is nowadays considered the most sophisticated method of treatment of chronic terminal renal insufficiency. The advancement in surgical technique and the use of new immunosuppressive medications provide a longer survival period of both the patient and the graft., Material and Methods: The objective of this paper is a retrospective presentation of the ten-year monitoring of kidney transplantation in patients undergoing peritoneal dialysis performed at the Military Medical Academy., Results and Discussion: During that period, 32 patients underwent the transplantation (18 men and 14 women of the average age of 32.48+/-2.1). The total of 34 transplantations were performed, out of which 2 were retransplantations. Patient monitoring period was 7-92 months. The immunosuppressive therapy was quadrupled in 17 (50%) patients and tripled in 17 (50%) of them. The loss of the graft in the early period following the transplantation occurred in 5 (15.6%) patients due to trombosis a. renalis, out of whom two were retransplantation cases. Registered surgical vascular complications included 5 (15.6%) bleeding, 4 (12.5%) hematomes and 6 (18.7%) lymfocells. Delayed graft function occurred in 5 (14.7%) and acute rejection in 7 (20.5%) patients while the disease reccured in 2 patients. As for the complications, rejection without the loss of graft was registered in 4 (12.5%) pts, ureter stenosis in 3 (8.82%) pts, bacterial infections in 4 (12.5%) pts and reactivation of CMV infections in 9 (26.4%) pts. Our patients are observed for the maintenance of stable medium volume of serum creatinine (which is 123.6 +/-10.2 umol/l in the early stage and 133.24+/-11.1 umol/l in the end of the monitoring period as well as the medium volume of clearence creatinine (which is 64.80+/-3.5 ml/min at the early phase of monitoring period and 69.47+/-3.3 ml/min. in the end)., Conclusion: Our group of renal transplantation patients, undergoing peritoneal dialysis was with stable renal function registered through the monitoring period.
