ABSTRACT

Strenuous exercise triggers deleterious effects on the intestinal epithelium, but their mechanisms are still uncertain. Here, we investigated whether a prolonged training and an additional exhaustive training protocol alter intestinal permeability and the putative effect of alanyl-glutamine (AG) pretreatment in this condition. Rats were allocated into 5 different groups: 1) sedentary; 2 and 3) trained (50 min per day, 5 days per week for 12 weeks) with or without 6 weeks oral (1.5 g/kg) AG supplementation; 4 and 5) trained and subjected to an additional exhaustive test protocol with or without oral AG supplementation. Venous blood samples were collected to determine gasometrical indices at the end of the 12-week protocol or after exhaustive test. Lactate and glucose levels were determined before, during, and after the exhaustive test. Ileum tissue collected after all experimental procedures was used for gene expression analysis of Zonula occludens 1 (ZO-1), occludin, claudin-2, and oligopeptide transporter 1 (PepT-1). Intestinal permeability was assessed by urinary lactulose/mannitol test collected after the 12-week protocol or the exhaustive test. The exhaustive test decreased pH and base excess and increased pCO2. Training sessions delayed exhaustion time and reduced the changes in blood glucose and lactate levels. Trained rats exhibited upregulation of PEPT-1, ZO-1, and occludin mRNA, which were partially protected by AG. Exhaustive exercise induced intestinal paracellular leakage associated with the upregulation of claudin-2, a phenomenon protected by AG treatment. Thus, AG partially prevented intestinal training adaptations but also blocked paracellular leakage during exhaustive exercise involving claudin-2 and occludin gene expression.

ABSTRACT

BACKGROUND: Scorpion venom causes renal injury and affects vascular ion-channels function. Centruroides margaritatus scorpion is found in Colombia and is frequently the cause of envenomation accidents; however, its renal impact has never been investigated. OBJECTIVE: To evaluate the effects of C. margaritatus venom (CmV) on renal parameters using isolated rat kidney and renal cell culture models. METHODS: Wistar rats (n = 5, weighing 240-300 g) were first perfused with Krebs-Henseleit solution containing 6 g 100 mL-1 bovine serum albumin. After 30 minutes, the kidneys were perfused with CmV to a final concentration of 10 µgmL-1; evaluation was performed by measuring Perfusion Pressure (PP), Renal Vascular Resistance (RVR), Urinary Flow (UF), Glomerular Filtration Rate (GFR), and percentage of electrolyte tubular transport. Moreover, kidney histological analyses and cell cytotoxicity in renal tubule epithelial cells (MDCK) and proximal tubular cells (LLC-MK2) were assessed. RESULTS: CmV increased PP and RVR 60 min after perfusion. On the other hand, UF, GFR, and the percentages of sodium, potassium and chloride tubular transport decreased after experimental envenomation. UF dropped after 120 min, while GFR and percentage of electrolyte tubular transport diminished after 60, 90 and 120 min. CmV was not toxic to MDCK cell line but reduced the viability of LLC-MK2 cells at concentrations ranging from 6.25 to 200 µgmL-1. Histological analyses disclosed hydropic degeneration, edema, and protein deposits. Flow cytometry disclosed that cell death occurred predominantly by necrosis. CONCLUSION: Our results suggest that C. margaritatus venom can trigger renal impairment, mainly in the proximal kidney tubule.

ABSTRACT

The transport of myo-inositol is the main mechanism for the maintenance of its high intracellular levels. We aimed to measure the mRNA and protein levels of myo-inositol cotransporters in the sciatic nerve (SN) and dorsal root ganglia (DRG) during experimental diabetes. Streptozotocin-induced (STZ; 4, 8, and 12 weeks; 65 mg/kg; ip) diabetic rats (DB) and age-matched euglycemic (E) rats were used for the analysis of mRNA and protein levels of sodium myo-inositol cotransporters 1, 2 (SMIT1, SMIT2) or H+/myo-inositol cotransporter (HMIT). There was a significant reduction in the mRNA levels for SMIT1 in the SN and DRG (by 36.9 and 31.0%) in the 4-week DB (DB4) group compared to the E group. SMIT2 was not expressed in SN. The mRNA level for SMIT2 was up-regulated only in the DRG in the DB4 group. On the other hand, the protein level of SMIT1 decreased by 42.5, 41.3, and 44.8% in the SN after 4, 8, and 12 weeks of diabetes, respectively. In addition, there was a decrease of 64.3 and 58.0% of HMIT in membrane and cytosolic fractions, respectively, in the SN of the DB4 group. In the DRG, there was an increase of 230 and 86.3% for SMIT1 and HMIT, respectively, in the DB12 group. The levels of the main inositol transporters, SMIT1 and HMIT, were greatly reduced in the SN but not in the DRG. SMIT-1 was selectively reduced in the sciatic nerve during experimental STZ-induced diabetes.

ABSTRACT

Epithelial cell migration is an essential response to enteric pathogens such as enteropathogenic Escherichia coli (EPEC). This study aimed to investigate the effects of EPEC infection on intestinal epithelial cell migration in vitro, as well as the involvement of type III secretion system (T3SS) and Rho GTPases. Crypt intestinal epithelial cells (IEC-6) were infected with EPEC strains (E2348/69, ΔescF, and the LDI001 strain isolated from a malnourished Brazilian child) and commensal E. coli HS. Wound migration and cell death assays were performed at different time-points. Transcription and expression of Rho GTPases were evaluated using real-time PCR and western blotting. Overall, EPEC E2348/69 reduced migration and increased apoptosis and necrosis levels compared to EPEC LDI001 and E. coli HS strains. Moreover, EPEC LDI001 impaired cell migration at a higher level than E. coli HS and increased necrosis after 24 hours compared to the control group. The different profiles of virulence genes between the two wild-type EPEC strains, characterized by the absence of espL and nleE genes in the LDI001, might explain the phenotypic results, playing significant roles on cell migration impairment and cell death-related events. Moreover, the type III secretion system is determinant for the inhibition of intestinal epithelial cell migration by EPEC 2348/69, as its deletion prevented the effect. Active Rac1 concentrations were increased in E2348/69 and LDI001-infected cells, while the T3SS-deficient strain did not demonstrate this activation. This study contributes with valuable insight to characterize the mechanisms involved in the impairment of intestinal cell migration induced by EPEC.

ABSTRACT

Undernutrition represents a major public health challenge for middle- and low-income countries. This study aimed to evaluate whether a multideficient Northeast Brazil regional basic diet (RBD) induces acute morphological and functional changes in the ileum of mice. Swiss mice (∼25 g) were allocated into two groups: i) control mice were fed a standard diet and II) undernourished mice were fed the RBD. After 7 days, mice were killed and the ileum collected for evaluation of electrophysiological parameters (Ussing chambers), transcription (RT-qPCR) and protein expression (western blotting) of intestinal transporters and tight junctions. Body weight gain was significantly decreased in the undernourished group, which also showed decreased crypt depth but no alterations in villus height. Electrophysiology measurements showed a reduced basal short circuit current (Isc) in the undernourished group, with no differences in transepithelial resistance. Specific substrate-evoked Isc related to affinity and efficacy (glutamine and alanyl-glutamine) were not different between groups, except for the maximum Isc (efficacy) induced by glucose. Transcription of Sglt1 and Pept1 was significantly higher in the undernourished group, while SN-2 transcription was decreased. No changes were found in transcription of CAT-1 and CFTR, while claudin-2 and occludin transcriptions were significantly increased in the undernourished group. Despite mRNA changes, SGLT-1, PEPT-1, claudin-2 and occludin protein expression showed no difference between groups. These results demonstrate early effects of the RBD on mice, which include reduced body weight and crypt depth in the absence of significant alterations to villus morphology, intestinal transporters and tight junction expression.

ABSTRACT

We evaluated retrospectively the incidence of acute kidney injury (AKI), defined by risk, injury, failure, loss and end-stage kidney disease (RIFLE) and its influence on long-term survival, in 82 patients aged 18-60 years who underwent a reduced intensity conditioning (RIC) haematopoietic cell transplantation (HCT). Patients (53.6%) developed AKI after HCT: 25% were on risk, 45.5% on injury and 29.5% on failure. In all, 64 patients survived after 100 days of post transplant and were available for long-term survival analysis. At follow-up, 43.7% of patients died. A 5-year overall survival of AKI patients was 41.6% as compared with 67.1% for those who did not develop AKI (P=0.028), and decreased according to AKI severity (risk, 55.6%; injury plus failure, 33.3%; P=0.045). After adjusting for age, history of cardiovascular disease, high-risk disease and chronic GVHD, AKI predicted 5-year overall mortality (AKI: adjusted hazards ratio (AHR), 2.36, 95% CI: 1.03-5.37; P=0.041). Moreover, moderate and severe AKI (injury plus failure) was also associated with an increased 5-year overall mortality (injury plus failure: AHR, 1.64, 95% CI: 1.06-2.54; P=0.024). According to RIFLE, 53.6% of patients had AKI after RIC HCT. Such patients have poor long-term survival, particularly in moderate or severe AKI.

ABSTRACT

The optimal prophylactic induction immunosuppressive therapy to prevent renal transplant rejection remains controversial. Recently, basiliximab efficiency has been reported in several studies. We sought to evaluate the efficiency of induction immunosuppressive therapy with basiliximab in renal transplantation in our unit based upon the acute rejection rate, patient and graft survivals, first hospital admission length, and incidence of infectious or malignant complications during 4 years of follow-up. We retrospectively evaluated the outcome of two groups of renal transplant recipients treated with triple immunosuppressive therapy (cyclosporine, mycophenolate mofetil, and prednisolone) without (group 1, 149 patients) or with (group 2, 104 patients) induction immunosuppression with basiliximab. The two groups did not differ in demographic characteristics, number of hypersensitized patients, cold ischemia time, or donor age. The group receiving basiliximab displayed a significantly lower acute rejection rate (7.6% vs 24%, P = .001) and shorter first hospital admission (14.4 +/- 8 vs 19.5 +/- 11 days). There was no difference in graft or patient survival, death due to sepsis, or incidence of posttransplant malignancies. Although there was no difference in graft or patient survival, immunosuppressive induction therapy with basiliximab yielded a significant reduction in the acute rejection rate.

ABSTRACT

Mycophenolate mofetil (MMF) use in renal transplantation has allowed a significant decrease in early acute rejection rates. We retrospectively evaluated the incidence of acute rejection episodes, renal function at the first year posttransplant, patient and graft survivals, cytomegalovirus (CMV) infection rate, influence of the degree of sensitization, and number of MHC antigen mismatches on graft survival in two groups of patients receiving either MMF or azathioprine. Group 1 included 149 patients receiving cyclosporine, MMF, and prednisolone; group 2 included 191 patients receiving cyclosporine, azathioprine, and prednisolone. The two groups did not differ in terms of age, sex, degree of sensitization (expressed as percentage of antibodies reactive to panel), MHC mismatch number, cold ischemia time, donor age, or anti-thymocyte globulin induction. In group 1 (MMF) there was a significant decrease in early acute rejection rate (19% vs 57%, P < .0001), longer graft survival at 10 years (92% vs 75%, P = .006), and higher rate of CMV infection (22% vs 12%, P = .004). Renal function at the first year posttransplant and patient survival during follow-up did not differ between the groups. The degree of sensitization influenced graft survival in group 2. The number of MHC mismatches did not influence graft survival in either group. With MMF, there was a significant reduction in early acute rejection rate, a significant increase in graft survival at 10-year follow-up, and diminished impact of the degree of sensitization on graft survival.

ABSTRACT

BACKGROUND: The long-term effect of recombinant human erythropoietin (rhEPO) on the blood-lipid profile has not been well documented. The aim of this study was to evaluate whether rhEPO therapy affects the lipid pattern. METHODS: A group of 102 maintenance haemodialysis patients were treated for 2 years with rhEPO given intravenously at the end of the dialysis session. Attempts were made to keep the haemoglobin (Hb) at 10-11 g/dl and/or the haematocrit (Hct) at 30-35%. Twenty maintenance haemodialysis patients not treated with rhEPO were examined as controls. Total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, apolipoproteins A1 and B, and lipoprotein (a)[Lp (a)] were assessed at baseline (without rhEPO), and 1 and 2 years after the beginning of treatment. Hb, Hct and ferritin were measured monthly, and Kt/v was evaluated monthly and kept above 1.1. RESULTS: During follow-up, in both groups, there was a significant increase in Apo A1 and no significant changes in the other lipid parameters. In the treated group, Hb and Hct increased significantly after the fourth month of treatment. CONCLUSIONS: Erythropoietin therapy does not affect significantly the levels of total cholesterol, LDL- and HDL-cholesterol, triglycerides, Apo B and Lp (a) in maintenance hemodialysis patients.
