Zocoler- Cardiovascular risk reduction with periodontal treatment in patients on the waiting list for renal transplantation(2019) SANTOS-PAUL, Marcela A.; NEVES, Ricardo Simoes; GOWDAK, Luis Henrique W.; PAULA, Flayio J. de; DAVID-NETO, Elias; BORTOLOTTO, Luiz A.; RAMIRES, Jose Antonio F.; LIMA, Jose Jayme G. DeBackground Cardiovascular mortality is increased in chronic kidney disease, a condition with a high prevalence of periodontal disease. Whether periodontitis treatment improves prognosis is unknown. Methods The effect of periodontal treatment on the incidence of cardiovascular events and death in 206 waitlist hemodialysis subjects was compared with that in 203 historical controls who did not undergo treatment. Patients were followed up for 24 months or until death or transplantation. Results The prevalence of moderate/severe periodontitis was 74%. Coronary artery disease correlated with the severity of periodontal disease (P = .02). Survival free of cardiovascular events (94% vs 83%, log-rank 0.009), coronary events (97% vs 89%, log-rank = 0.009), and cardiovascular death (96% vs 87%, log-rank = 0.037) was higher in the evaluated group. Death by any cause did not differ between groups. Multivariate analysis showed that treatment was associated with reduction in cardiovascular events (HR 0.43; 95% CI 0.22-0.87), coronary events (HR 0.31; 95% CI 0.12-0.83), and cardiovascular deaths (HR 0.43; 95% CI 0.19-0.98). Conclusion Periodontal treatment reduced the 24-month incidence of cardiovascular events and cardiovascular death, suggesting that periodontal treatment may improve cardiovascular outcomes. We suggest that periodontal screening and eventual treatment may be considered in patients with advanced renal disease.

C.- The role of therapy with aminoglycoside in the outcomes of kidney transplant recipients infected with polymyxin- and carbapenem-resistant Enterobacteriaceae(2019) FREIRE, Maristela P.; GARCIA, Doroti de Oliveira; CURY, Ana Paula; FRANCISCO, Gabriela R.; SANTOS, Nathamy F. dos; SPADAO, Fernanda; BUENO, Maria Fernanda Campagnari; CAMARGO, Carlos Henrique; PAULA, Flavio J. de; ROSSI, Flavia; NAHAS, Willian C.; DAVID-NETO, Elias; PIERROTTI, Ligia C.Kidney transplant recipients are at risk for infections due to carbapenem-resistant Enterobacteriaceae (CRE). Polymyxin-resistant CRE (PR-CRE) infections are especially difficult to treat. The aim of this study was to characterize PR-CRE infections among kidney transplant recipients and identify risk factors for treatment failure. This retrospective cohort study involved all kidney transplant recipients with PR-CRE infection between 2013 and 2017 at our center. Minimal inhibitory concentrations for polymyxin B were determined by broth microdilution. Carbapenem-resistant genes (bla(KPC), bla(NDM), and bla(OXA-48)), aminoglycoside-resistance genes, and polymyxin-resistant gene mcr-1 were identified by polymerase chain reaction. All but one of the 47PR-CRE infections identified were due to Klebsiella pneumoniae. The most common type of infection (in 54.3%) was urinary tract infection (UTI). Monotherapy was used in 10 cases. Combined treatment regimens included double-carbapenem therapy in 19 cases, oral fosfomycin in 19, and amikacin in 13. Treatment failure occurred in 21 cases (45.7%). Clinical success was achieved 78.9% of patients who used aminoglycosides versus 37.0% of those who not used this drug (p=0.007). Multivariate analysis showed diabetes mellitus to be a risk factor for treatment failure; amikacin use and UTI were found to be protective. Nine strains were RmtB producers. Although aminoglycosides constitute an important therapeutic option for PR-CRE infection, the emergence of aminoglycoside resistance could have a major impact on the management of CRE infection.
- Effect of polyoma viremia on 3-year allograft kidney function(2019) DAVID-NETO, Elias; AGENA, Fabiana; DAVID, Daisa Silva Ribeiro; PAULA, Flavio Jota de; PIERROTTI, Ligia Camera; FINK, Maria Cristina Domingues; AZEVEDO, Luiz Sergio Fonseca deBackground Polyoma viremia is associated with damage to renal tubular and urothelial cells. This may imply that a certain level of viremia, even cleared thereafter, could be associated with long-term renal dysfunction. Methods We, retrospectively, analyzed 390 first renal transplants adult recipients (>= 18 years) who were monitored for BK viremia in the first 12 months and evaluated estimated GFR (MDRD-4 equation) at 1 month and at the last follow-up (959 +/- 392 days). Results One hundred and ninety-nine patients (51%) developed at least one positive viremia: 105 (53%) low viremia (<10(4) copies/mL), 36 (18%) high viremia (4 x 10(4) > viremia >= 10(4) copies/mL) and 58 (15%) viremia (>= 4 x 10(4) copies/mL) consistent with polyoma virus associated nephropathy (PyVAN). Out of these 58 patients, 24 (6%) developed bx-proven (SV40+) PyVAN and 34(8.7%) presumptive PyVAN (SV40-). Baseline characteristics, immunosuppression, KDRI, rejection episodes, etc., did not differ among groups but there were more deceased donors and ATG induction therapy in the high viremia group. At last follow-up, all patients in the low, high viremia and presumptive PyVAN (except 2) had cleared BK viremia. Bx-proven PyVAN led to 14 graft losses, 10 due to PyVAN. In the presumptive PyVAN there was only one graft loss registered as due to PyVAN. eGFR, at 1 month after KTx, did not differ among groups (51 +/- 22 vs 48 +/- 24 vs 45 +/- 27 vs 43 +/- 18 vs 46 +/- 22 mL/min/1.73 m(2)), for no, low and high viremia as well for presumptive PyVAN and bx-proven PyVAN groups, respectively. At the last follow-up, eGFR did not differ between the no, low, and high viremia compared to baseline and to each other but was statistically lower in the presumptive and bx-proven PyVAN (38 +/- 15 and 17 +/- 7 mL/min/1.73 m(2)) either compared to baseline or to the other groups. Conclusions This study shows that low and high levels of BK viremia do not lead to GFR changes although very high viremia levels, compatible with presumptive or bx-proven PyVAN, even if cleared thereafter, lead to allograft damage and decreased GFR.
