RESUMEN

AIM: To evaluate the vaccine response and the effect of the booster dose on COVID-19 positivity in haemodialysis (HD) and peritoneal dialysis (PD) patients who received and did not receive BNT162b2 as a booster dose after two doses of CoronaVac. METHODS: The study included 80 PD and 163 HD patients, who had been administered two doses of the CoronaVac. Antibody levels were measured on Days 42 and 90 after the first dose. Measurements were repeated on Day 181 after the first dose in the patients that received two vaccine doses and on Day 28 after the third dose in those that also received the booster dose. Antibody levels below 50 AU/mL were considered negative. RESULTS: The seropositivity rate was similar in the HD and PD group on Days 42 and 90 (p = 0.212 and 0.720). All patients were seropositive in the booster group. The antibody level was lower in the patients that received CoronaVac as the booster compared to those administered BNT162b2 in HD and PD groups (p < 0.001 and 0.002). COVID-19 positivity was detected in 11 patients (7 = had not received the booster dose, 4 = had received third dose of CoronaVac). The multivariate analysis revealed that as age increased, COVID-19 positivity also increased (OR: 1.080, 95% CI: 1.017 - 1.146, p = 0.012), while booster dose administration decreased this positivity (OR: 0.113, 95% CI: 0.028 - 0.457, p = 0.002). CONCLUSION: Our results may indicate the need for additional vaccination doses in patients with HD and PD. Our findings indicate a higher antibody response in dialysis patients with heterologous BNT162b2 as a booster dose after two doses of CoronaVac compared to homologous CoronaVac.

RESUMEN

BACKGROUND: Immunoglobulin A (IgA) nephropathy (IgAN) treatment consists of maximal supportive care and, for high-risk individuals, immunosuppressive treatment (IST). There are conflicting results regarding IST. Therefore, we aimed to investigate IST results among IgAN patients in Turkiye. METHOD: The data of 1656 IgAN patients in the Primary Glomerular Diseases Study of the Turkish Society of Nephrology Glomerular Diseases Study Group were analyzed. A total of 408 primary IgAN patients treated with IST (65.4% male, mean age 38.4 ± 12.5 years, follow-up 30 (3-218) months) were included and divided into two groups according to treatment protocols (isolated corticosteroid [CS] 70.6% and combined IST 29.4%). Treatment responses, associated factors were analyzed. RESULTS: Remission (66.7% partial, 33.7% complete) was achieved in 74.7% of patients. Baseline systolic blood pressure, mean arterial pressure, and proteinuria levels were lower in responsives. Remission was achieved at significantly higher rates in the CS group (78% vs. 66.7%, p = 0.016). Partial remission was the prominent remission type. The remission rate was significantly higher among patients with segmental sclerosis compared to those without (60.4% vs. 49%, p = 0.047). In the multivariate analysis, MEST-C S1 (HR 1.43, 95% CI 1.08-1.89, p = 0.013), MEST-C T1 (HR 0.68, 95% CI 0.51-0.91, p = 0.008) and combined IST (HR 0.66, 95% CI 0.49-0.91, p = 0.009) were found to be significant regarding remission. CONCLUSION: CS can significantly improve remission in high-risk Turkish IgAN patients, despite the reliance on non-quantitative endpoints for favorable renal outcomes. Key predictors of remission include baseline proteinuria and specific histological markers. It is crucial to carefully weigh the risks and benefits of immunosuppressive therapy for these patients.

RESUMEN

INTRODUCTION: There is insufficient data on the role of the medium cutoff (MCO) membranes in the clearance of pro-inflammatory cytokines and oxidant radicals in patients with sepsis requiring hemodialysis. METHODS: The study consisted of 38 septic patients who developed acute kidney injury (AKI) and who were scheduled to undergo 2 sessions of hemodialysis. Nineteen patients underwent their first dialysis session with the MCO membrane and 19 patients with the high-flux (HF) membrane. In the second session, the membranes were switched. Pro-inflammatory cytokine and oxidative marker levels were measured in blood samples obtained before and after both dialysis sessions. Reduction ratios were compared for the 2 types of hemodialysis membranes. RESULTS: After the first session, there was a greater reduction in tumor necrosis factor (TNF)-α with the MCO membrane (28.2 ± 21.1 vs. 8.0 ± 6.6, p = 0.001). After the second session, there was a greater reduction in interleukin (IL)-6 (27.8 ± 26.5 vs. 5.9 ± 13.3, p = 0.003) and IL-1ß (20.5 ± 21.1 vs. 4.0 ± 6.5, p = 0.004) with the MCO membrane. When the first and second sessions of all 38 patients were compared, the reductions in TNF-α, IL-6, and IL-1ß were consistently greater for MCO than HF (p = 0.001, p = 0.006, p < 0.001, respectively). The reductions in total antioxidant status, total oxidant status, and myeloperoxidase were not statistically different for the 2 types of dialysis membranes. CONCLUSIONS: MCO membrane was superior to HF membrane in the removal of cytokines in septic patients with AKI. However, a similar effect was not observed for oxidative stress markers.

RESUMEN

Eggerthia catenaformis is a Gram-positive bacilli and an anaerobic and non-spore-forming bacterium, which rarely causes infections in humans. We present a case of peritonitis caused by E. catenaformis in a peritoneal dialysis patient. The isolate was identified as E. catenaformis with the MALDI-TOF MS method as in other cases in the literature. To the best of our knowledge, this is the first case of peritonitis caused by E. catenaformis in a human host.

RESUMEN

BACKGROUND: Galactose-deficient IgA1 (Gd-IgA1) has an increased tendency to form immunocomplexes with IgG in the serum, contributing to IgAN pathogenesis by accumulating in the glomerular mesangium. Several studies showed that glomerular IgG deposition in IgAN is an important cause of mesangial proliferation and glomerular damage. This study aims to determine the association of the positivity of IgG and the intensity of IgG staining with a poor renal prognosis. METHODS: A total of 943 IgAN patients were included in the study. Glomerular IgG staining negative and positive patients were compared using Oxford classification scores, histopathological evaluations, proteinuria, eGFR, albumin, blood pressures. IgG positive patients were classified as (+), (++), (+++) based on their staining intensity, and the association with the prognostic criteria was also evaluated. RESULTS: 81% (n = 764) of the patients were detected as IgG negative, while 19% (n = 179) were positive. Age, gender, body mass index, blood pressure, proteinuria, eGFR, uric acid values were similar in IgG positive and negative patients who underwent biopsy (p > 0.05). Intensity of glomerular IgG positivity was not found to be associated with diastolic and systolic blood pressure, urea, uric acid, age, eGFR, albumin, proteinuria (p > 0.05 for all, r = - 0.084, r = - 0.102, r = - 0.006, r = 0.062, r = 0.014, r = - 0.044, r = - 0.061, r = - 0.066, r = 0.150, respectively). There was no difference for histopathological findings between IgG (+), IgG (++), IgG (+++) groups (for all, p > 0.05). CONCLUSION: Glomerular IgG negativity and positivity detected by routine IFM in IgAN patients is not associated with poor renal prognostic risk factors.

RESUMEN

Background/aim: Neutrophil gelatinase-associated lipocalin (NGAL) is used previously to estimate the etiology, severity, and clinical outcomes of acute kidney injury (AKI). However, the role of urinary NGAL (uNGAL) in the postrenal setting is not clear. In our study, we aimed to discover the cut-off value of uNGAL that can be used in the differential diagnosis of underlying AKI etiologies. Materials and methods: In this prospective cross-sectional study, we examined 82 subjects in four groups: patients that had (1) postrenal AKI; (2) AKI other than postrenal etiologies; (3) stable chronic kidney disease; and (4) healthy subjects. A renal function assessment was carried out by measuring serum creatinine (sCr) and uNGAL at the time of diagnosis [0th min (T0)]. We followed the study group for three months. Results: At the time of diagnosis, sCr (T0) was highest in the postrenal AKI and AKI groups in contrast to stable chronic kidney disease patients and healthy subjects (P < 0.001), as expected. T0 median uNGAL was highest in the postrenal group (P < 0.001). Area under curve (AUC) of uNGAL to estimate postrenal AKI presence was 0.957 (95% CI, 0.897­1.000; P < 0.001). The cut-off point of uNGAL was 42.625 ng/mL for this estimation. Conclusion: Patients with AKI must be classified according to the underlying etiologies as soon as possible. uNGAL may be useful to estimate the etiologies, and whether the problem is acute or chronic in the course. In postrenal kidney problems, to plan the urgency of the urologic procedures, it is crucial.

RESUMEN

BACKGROUND: Blood from patients who are receiving anticoagulant therapy may take longer to clot. Anticoagulation is an important component of the dialysis prescription. We compared BD Vacutainer® Barricor™ Plasma Blood Collection Tubes (BD BarrricorTM), BD Vacutainer® PST™ Lithium Heparin Tubes (BD PST™), and BD (Becton-Dickinson, Franklin Lakes, NJ, USA) Vacutainer Serum Separator Tubes (BD SST), as reference tube in dialysis patients to examine whether they had an effect on routine biochemical tests. MATERIALS AND METHODS: A total of 29 chronic hemodialysis patients were included in this study. Samples were collected into BD BarrricorTM, BD PST™, and BD SST tubes after the dialysis. All the tubes were centrifuged by NF 1200R rotor (1,300 g for 10 minutes at 22°C, 1,200 g for 10 minutes at 4°C, 2,400 g for 10 minutes at 22°C, respectively) after the incubation period. Eleven routine clinical chemistry parameters (Creatinine, Urea, Na, K, Cl, AST, ALT, Total Bilirubin, Direct Bilirubin, Calcium, Cholesterol) were analyzed on a Beckman Coulter AU 5800. RESULTS: Results of creatinine, K and cholesterol were statistically significantly different between the SST and LiH (p = 0.014, p = 0.009, and p < 0.001, respectively). In terms of other biochemical parameters we tested for all three tubes there was no clinically significance inspite of the statistically significance. CONCLUSIONS: BD Barricor™ tubes provide fast, clean, high-quality plasma samples, safe results, and may lower times and costs.

RESUMEN

The data regarding primary FSGS (pFSGS) from different parts of the world differ. While the prevalence of pFSGS has been increasing in Western countries like the USA, it follows an inconsistent trend in Europe and Asia and a decreasing trend in Far Eastern countries such as China in the last two decades. There are undetermined factors to explain those national and geographic discrepancies. Herein, we aimed to reveal the current prevalence with clinical and histopathological characteristics of pFSGS in Turkish adults. This study includes the biopsy-proven pFSGS patients data recorded between 2009 and 2019, obtained from the national multicenter primary glomerulonephritis registry system of the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) database. 850 of the 3875 primer glomerulonephritis patients(21.9%) have pFSGS. The mean age is 40.5 ± 14.2 and 435 (51.2%) of patients are male. Nephrotic syndrome is the most common biopsy indication (59.2%). 32.6% of patients have hematuria, 15.2% have leukocyturia and 7.8% have both. Serum creatinine, albumin, and proteinuria are 1.0 mg/dL (IQR = 0.7-1.4) mg/dl, 3.4 ± 0.9 g/dl, 3400 mg/day(IQR, 1774-5740), respectively. Females have lower mean arterial pressure (- 2.2 mmHg), higher eGFR (+ 10.0 mL/min/1.73 m2), and BMI (+ 1.6 kg/m2) than males. Thickened basal membrane(76.6%) and mesangial proliferation (53.5%) on light microscopy are the major findings after segmental sclerosis. IgM (32.7%) and C3 (32.9%) depositions are the most common findings on immunofluorescence microscopy. IgM positivity is related to lower eGFR, serum albumin, and higher proteinuria. The prevalence of pFSGS is stable although slightly increasing in Turkish adults. The characteristics of the patients are similar to those seen in Western countries.

RESUMEN

OBJECTIVE:  Latent tuberculosis infection (LTBI) screening is strongly recommended in the pre-transplant evaluation of solid organ transplant (SOT) recipients, although it remains inadequate in many transplant centers. We decided to investigate pre-transplant TB risk assessment, LTBI treatment, and registry rates in Turkey. MATERIAL AND METHODS:  Adult SOT recipients who underwent tuberculin skin test (TST) and/or interferon-gamma release test (IGRA) from 14 centers between 2015 and 2019 were included in the study. An induration of ≥5 mm on TST and/or probable/positive IGRA (QuantiFERON-TB) was considered positive for LTBI. Demographic features, LTBI screening and treatment, and pre-/post-transplant TB history were recorded from the electronic database of transplantation units across the country and pooled at a single center for a unified database. RESULTS:  TST and/or IGRA were performed in 766 (33.8%) of 2266 screened patients most of whom were kidney transplant recipients (n = 485, 63.4%). LTBI screening test was positive in 359 (46.9%) patients, and isoniazid was given to 203 (56.5%) patients. Of the patients treated for LTBI, 112 (55.2%) were registered in the national registry, and 82 (73.2%) completed the treatment. Tuberculosis developed in 6 (1.06%) of 563 patients who were not offered LTBI treatment. CONCLUSION:  We determined that overall, only one-third of SOT recipients in our country were evaluated in terms of TB risk, only 1 of the 2 SOT recipients with LTBI received treatment, and half were registered. Therefore, we want to emphasize the critical importance of pretransplant TB risk stratification and registration, guided by revised national guidelines.

RESUMEN

INTRODUCTION: Hypertension is an early finding of autosomal dominant polycystic kidney disease (ADPKD) and is related to different mechanisms. Cyst expansion-related renin secretion or early endothelial dysfunctions are some of these hypotheses. In addition, the underlying genetic factor is thought to play a role in the inheritance of hypertension. The differential course of hypertension in ADPKD preoccupies that relatives of ADPKD patients may also be at risk for this underlying mechanisms with a genetically determined abnormal endothelial-vascular state. In this study, we aimed to evaluate blood pressure response to exercise as an initial vascular problem in unaffected and normotensive relatives of hypertensive ADPKD patients. METHODS: This is an observational study including unaffected and normotensive relatives (siblings and children) of ADPKD patients (relative group) and healthy controls (control group) who performed an exercise stress test. A 6-lead electrocardiogram was recorded and blood pressure was measured automatically with a cuff worn on the right arm, immediately before the test and every 3 min during the exercise and the recovery phase. Participants continued the test until their age-specific target heart rate was reached or symptoms occurred that required discontinuation of the test. The highest blood pressure and pulse values during exercise were noted. In addition, as a marker for endothelial function, nitric oxide (NO) and asymmetric dimethylarginine (ADMA) levels were measured at baseline and post-exercise. RESULTS: There were 24 participants in the relative group (16 female, mean age 38.45 years) and 30 participants in the control group (15 female, mean age 37.96 years). Two groups were similar in terms of age, gender, body mass index (BMI), smoking status, resting systolic blood pressure (SBP)/diastolic blood pressure (DBP) and biochemical parameters. Mean SBP and DBP were similar in both groups during 1st, 3rd and 9th minutes of exercise (1st minute: 136.25 ± 19.71 mmHg vs 140.36 ± 30.79 mmHg for SBP, p = 0.607, 84.05 ± 14.75 mmHg vs 82.60 ± 21.60 mmHg for DBP, p = 0.799; 3rd minute: 150.75 ± 30.39 mmHg vs 148.54 ± 27.30 mmHg for SBP, p = 0.801, 98.95 ± 26.92 mmHg vs 85.92 ± 17.93 mmHg for DBP, p = 0.062; 9th minute: 156.35 ± 30.84 mmHg vs 166.43 ± 31.90 mmHg for SBP, p = 0.300, 96.25 ± 21.99 mmHg vs 101.78 ± 33.11 mmHg for DBP, p = 0.529 for control and relatives, respectively). During the recovery phase, SBP decreased in both groups in 6th minute (119.85 ± 14.06 mmHg vs 122.86 ± 16.76 mmHg, p = 0.538 for control and relatives respectively); however, in the relatives of ADPKD patients DBP remained high at the end of the 6th minute (78.95 ± 11.29 mmHg vs 86.67 ± 9.81 mmHg p = 0.025 for control and relatives, respectively). Baseline and post-exercise NO and ADMA levels were similar in both groups (Baseline p = 0.214 and p = 0.818, post-exercise p = 0.652 and p = 0.918 for NO and ADMA, respectively). CONCLUSION: Abnormal blood pressure response to exercise was observed in unaffected normotensive relatives of ADPKD. Although its clinical significance needs to be demonstrated by additional research, it is an important finding that unaffected relatives of ADPKD may be at risk for an altered arterial vascular network. Furthermore, these data are the first to demonstrate that relatives of ADPKD patients may also be under risk with a genetically determined abnormal vascular state.

RESUMEN

We evaluated neutralizing antibodies against the Omicron variant and Anti-Spike IgG response in solid organ (SOT) or hematopoietic stem cell (HSTC) recipients after a third dose of BNT162b2 (BNT) or CoronaVac (CV) following two doses of CV. In total, 95 participants underwent SOT (n = 62; 44 liver, 18 kidney) or HSCT (n = 27; 5 allogeneic, 22 autologous) were included from five centers in Turkey. The median time between third doses and serum sampling was 154 days (range between 15 to 381). The vaccine-induced antibody responses of both neutralizing antibodies and Anti-Spike IgGs were assessed by plaque neutralizing assay and immunoassay, respectively. Neutralizing antibody and Anti-Spike IgG levels were significantly higher in transplant patients receiving BNT compared to those receiving CV (Geometric mean (GMT):26.76 vs. 10.89; p = 0.03 and 2116 Au/mL vs. 172.1 Au/mL; p < 0.001). Solid organ transplantation recipients, particularly liver transplant recipients, showed lower antibody levels than HSCT recipients. Thus, among HSCT recipients, the GMT after BNT was 91.29 and it was 15.81 in the SOT group (p < 0.001). In SOT, antibody levels after BNT in kidney transplantation recipients were significantly higher than those in liver transplantation recipients (GMT: 48.32 vs. 11.72) (p < 0.001). Moreover, the neutralizing antibody levels after CV were very low (GMT: 10.81) in kidney transplantation recipients and below the detection limit (<10) in liver transplant recipients. This study highlights the superiority of BNT responses against Omicron as a third dose among transplant recipients after two doses of CV. The lack of neutralizing antibodies against Omicron after CV in liver transplant recipients should be taken into consideration, particularly in countries where inactivated vaccines are available in addition to mRNA vaccines.

RESUMEN

AIM: Internal jugular vein (IJV) catheterization is often required to gain access for haemodialysis. Use of ultrasound guidance has reduced the complication rates of this procedure. We hypothesized that nephrologists may perform IJV cannulation with a high technical success and low immediate complication rates under real-time ultrasound guidance. METHODS: We prospectively analyzed 323 patients (186 male, 137 female) who underwent IJV cannulation with real-time ultrasound guidance. The number of needle punctures, technical success, the time between injection of local anaesthetic and entry into the IJV, and immediate complications were recorded. Patients with a history of multiple catheter insertions, previous difficulties during catheterization, poor compliance, obesity, impaired consciousness, skeletal deformity, disorder of haemostasis were regarded as high-risk group. RESULTS: Cannulation of IJV was achieved in all patients. Of the 323 catheters, 125 (38.7%) were placed in high-risk patients. Average number of puncture was 1.26 (range, 1-4). IJV was entered on the first attempt in 261 (80.8%) patients. Only ten complications (10/323, 3.2%) developed; five (2.5%) in the normal-risk group, and five (4.0%) in the high-risk group. Cannulation of IJV took a longer time in the high-risk group than in the normal-risk group. The number of needle punctures, percent of successful cannulation on the first attempt, and the frequency of complications were similar between the high- and normal-risk groups. CONCLUSIONS: Cannulation of IJV under real-time ultrasound guidance is very safe with high technical success rates. Nephrologists can use this technique with ease and with minimal complications in normal- and high-risk patients.

RESUMEN

We hereby describe a 49-year-old woman with acute renal failure due to tubulointerstitial nephritis and uveitis (TINU) syndrome. This patient presented with vomiting and nausea and was found to have chronic uveitis, elevated creatinine, and interstitial nephritis. The combination of tubulointerstitial nephritis and uveitis emerged the diagnosis of TINU syndrome after a stepwise examination for differential diagnosis. Clinical course and renal function improved quickly on oral steroids but not to normal range. TINU syndrome, although known to some ophthalmologists and nephrologists, is still rather obscure. TINU syndrome should be considered in patients with uveitis in combination with acute renal failure. The prognosis for the renal disorder is excellent, although the uveitis often recurs or remains chronic.

RESUMEN

Thrombotic thrombocytopenic purpura (TTP) is an uncommon cause of hematological and renal abnormalities in the postoperative period. An association between TTP and orthopedic surgery, a rare entity, has been reported in the literature. It has the strong possibility of being fatal and therefore should be treated immediately, mostly by plasmapheresis. We report a 15-year-old girl of TTP following a high tibial valgus osteotomy (HTO).

RESUMEN

A 56-year-old male admitted to the hospital for generalized weakness and fever. He was treated in hospital for 10 days due to COVID-19. He did not receive any immunosuppressive therapy during admission. One day after his discharge he experienced back pain and received analgesic therapy for 10 days. About one month later he experienced severe back pain and gross hematuria. He was admitted to hospital with acute kidney injury and new-onset lower extremity muscle weakness. His renal biopsy revealed IgA nephropathy and thoracic/cervical/lumbar-spine imaging showed an epidural abscess. This is a unique case report of a patient developing an epidural abscess and acute kidney injury together as a serious complication of COVID-19 infection.

RESUMEN

OBJECTIVE: Systemic amyloidosis may affect many organs, and may cause endocrinologic problems which may result in adrenal insufficiency. However, assessment of adrenocortical reserve is challenging in amyloidosis patients with renal involvement. We aimed to evaluate adrenocortical reserve with various methods of cortisol measurement to determine any occult clinical condition. METHODS: Patients with renal amyloidosis and healthy subjects were evaluated in this cross-sectional study. Basal cortisol, corticosteroid-binding globulin (CBG), and albumin levels were measured. Serum free cortisol (cFC) level was calculated. Cortisol response tests performed after ACTH stimulation test (250 µg, intravenously) were evaluated, and free cortisol index (FCI) was calculated. RESULTS: Twenty renal amyloidosis patients, and 25 healthy control subjects were included in the study. Patients and control subjects had similar median serum baseline cortisol levels [258 (126-423) vs 350 (314-391) nmol/L, p=0.169)] whereas patients' stimulated cortisol levels at the 60th minute were lower [624 (497-685) vs 743 (674-781) nmol/L, p=0.011)]. The 60th-minute total cortisol levels of 8 of the 20 (40%) amyloidosis patients were <500 nmol/L, but only three of these 8 patients had stimulated FCI <12 nmol/mg suggesting an adrenal insufficiency (15%). CONCLUSION: ACTH stimulation test and cortisol measurements should be considered in renal amyloidosis patients with severe proteinuria to avoid false positive results if only ACTH stimulation test is used. It will be appropriate to evaluate this group of patients together with estimated measurements as FCI.

RESUMEN

INTRODUCTION: Calcium channel blockers (CCBs) are commonly used agents in the treatment of hypertension as part of monotherapy or combination therapy. Peripheral edema is the most common side effect that requires discontinuation or replacement of treatment. Some studies in the literature have shown that long-acting dihydropyridine type CCBs lead chylous ascites in peritoneal dialysis patients. However, amlodipine-associated serous ascites cases are not available in the literature. CASE REPORT: In this case report, we describe a rare case of amlodipine induced massive ascites in a 30-year-old male with renal transplantation. CONCLUSION: We aimed to create awareness that pharmacologic causes should be considered in cases of ascites of unknown aetiology.

RESUMEN

OBJECTIVES: Helicobacter pylori (H. pylori) chronically infects the human stomach and may cause extra-gastrointestinal diseases. The role of H. pylori in the pathogenesis of atherosclerosis and its effect on lipids remains controversial. The aim of this study was to examine lipid levels in patients with and without H. pylori infection. METHODS: A total of 244 consecutive patients who underwent esophagogastroduodenoscopy were included in this study. Patients receiving statin and fibrate therapy and diabetic patients were excluded. Biopsies from each individual were taken and analyzed for H. pylori detection using ultrastructural methods. Patients were divided into two groups: H. pylori (+) (group 1) and H. pylori (-) (group 2). Total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride levels were measured in all subjects. RESULTS: A total of 163 patients were included in group 1 and 81 patients were included in group 2. Frequency of H. pylori was 67% in the study population. Total cholesterol (204 +/- 39 mg/dl versus 189 +/- 42 mg/dl, respectively; P = 0.007) and LDL-C (128 +/- 30 mg/dl versus 116 +/- 32 mg/dl, respectively; P = 0.003) were significantly higher in group 1 than in group 2. Updated Sydney classification score showed a positive correlation with LDL-C (r = 0.333, P < 0.001) and TC (r = 0.288, P < 0.001) levels. CONCLUSION: Increased levels of TC and LDL-C were found in patients infected with H. pylori, and updated Sydney System score showed a positive correlation with LDL-C and TC levels. These findings may explain why H. pylori infection is associated with increased risk of atherosclerosis.

RESUMEN

Scleroderma renal crisis (SRC) is a complication of systemic sclerosis characterized by the sudden onset of accelerated arterial hypertension, followed by progressive renal failure. Rarely, patients with SRC may be normotensive on presentation. These patients have poorer prognosis and higher mortality rates than those with hypertensive SRC. This is partly explained by the insidious course of normotensive SRC leading to delayed diagnosis and treatment. Normotensive patients also seem to be less responsive to current treatment modalities. Since available data on etiology, pathogenesis, and risk factors of the disease are inadequate, no effective therapy has been established to date. We report a patient with diffuse cutaneous scleroderma who developed SRC during his hospitalization. The patient remained normotensive and had an insidious course until oliguria and signs of hypervolemia occurred. Etiology, pathogenesis, risk factors, diagnosis, treatment modalities and prognosis of normotensive SRC are also discussed through previously published reports.

RESUMEN

OBJECTIVE: Previous studies suggest that the level of clinical insight in schizophrenia patients is related to working memory functions. However, these studies were not specifically concerned with the components of working memory and had not focused in detail on working memory functions. For this reason, the current study investigated the relationship between clinical insight and working memory components in patients with schizophrenia and schizoaffective disorder.  METHOD: The patient group was evaluated by using the Scale for Assessment of Negative Symptoms, the Scale for Assessment of Positive Symptoms, and the Scale to Assess Unawareness of Mental Disorder to measure clinical insight. Moreover, all participants underwent a "Situation Awareness" test in order to measure working memory functions. Based on published data, the first stage of this test was accepted to measure the "visual spatial sketchpad" component of working memory, and the second stage was accepted to measure the "episodic buffer" (bound information storage) component. The functions of these components were measured separately as top-down and bottom-up cognitive processes.  RESULTS: The episodic buffer function (managed by the bottom-up cognitive process) was related with clinical insight. This relationship also continued after correcting for the effect of positive symptoms on insight. The patients performed worse than the controls in terms of visual spatial sketchpad function, which was managed by both topdown and bottom-up cognitive processes. The patients performed worse than the controls in terms of both top-down and bottom-up cognitive processes and visual spatial sketchpad function. Furthermore, the patients were also worse than the controls in terms of episodic buffer function (managed by top-down cognitive processes).  CONCLUSION: Clinical insight may be associated with binding function (associated with episodic buffer function) managed by bottom-up cognitive processes in patients with schizophrenia and schizoaffective disorder. Further studies are necessary to confirm this novel finding.
