- Effect of Penicillin G Every Three Weeks on Oral Microflora by Penicillin Resistant Viridans Streptococci(2012) AGUIAR, Andre Andrade de; SAMPAIO, Roney Orismar; SAMPAIO, Jorge Luiz de Mello; SPINA, Guilherme Sobreira; NEVES, Ricardo Simoes; MOREIRA, Luiz Felipe Pinho; GRINBERG, MaxBackground: Benzathine penicillin G every 3 weeks is the standard protocol for secondary prophylaxis for recurrent rheumatic fever. Objective: Assess the effect of Benzathine penicillin G on Streptococcus sanguinis and in patients with cardiac valvular disease due to rheumatic fever receiving secondary prophylaxis. Methods: Oral streptococci were evaluated before (baseline) and 7 days (day 7) after Benzathine penicillin G in 100 patients receiving routine secondary rheumatic fever prophylaxis. Saliva samples were evaluated for colony count and presence of S. sanguinis and S. oralis. Chewing-stimulated saliva samples were serially diluted and plated onto both nonselective and selective 5% sheep blood agar containing penicillin G. The species were identified using conventional biochemical tests. Minimal inhibitory concentrations were determined with the Etest. Results: No statistical differences were found in the presence of S. sanguinis comparing baseline and day 7 (p = 0.62). However, the existing number of positive cultures of S. oralis on day 7 after Benzathine penicillin G presented a significant increase compared to baseline (p = 0.04). No statistical difference was found between baseline and day 7 concerning the number of S. sanguinis or S. oralis CFU/mL and median minimal inhibitory concentrations. Conclusion: This study showed that Benzathine penicillin G every 3 weeks did not change the colonization by S. sanguinis, but increased colonization of S. oralis on day 7 of administration. Therefore, susceptibility of Streptococcus sanguinis and Streptococcus oralis to penicillin G was not modified during the penicillin G routine secondary rheumatic fever prophylaxis.

- Heyde's Syndrome: Therapeutic Strategies and Long-Term Follow-Up(2021) ROSA, Vitor Emer Egypto; RIBEIRO, Henrique Barbosa; FERNANDES, Joao Ricardo Cordeiro; SANTIS, Antonio de; SPINA, Guilherme Sobreira; PAIXAO, Milena Ribeiro; PIRES, Lucas Jose Tachotti; BETTEGA, Marcelo; ACCORSI, Tarso Augusto Duenhas; SAMPAIO, Roney Orismar; TARASOUTCHI, FlavioBackground: Heyde's syndrome is the association of severe aortic stenosis with episodes of gastrointestinal due to angiodysplastic lesion. Little is known about the factors associated with new episodes of bleeding and long-term outcomes. Furthermore, most data are restricted to case reports and small case series. Objective: To assess the clinical, laboratory and echocardiography profile of patients with Heyde's syndrome who underwent valve intervention or drug therapy. Methods: Prospective cohort of 24 consecutive patients from 2005 to 2018. Clinical, laboratory and echocardiography data were assessed, as well as those related to valve intervention and to outcomes after diagnosis. Statistical significance was set p < 0.05. Results: Half of the 24 patients (50%) presented with bleeding requiring blood transfusion on admission. Angiodysplasias were more frequently found in the ascending colon (62%). Valve intervention (surgical or transcatheter) was performed in 70.8% of the patients, and 29.2% remained on drug therapy. News episodes of bleeding occurred in 25% of the cases, and there was no difference between clinical and intervention groups (28.6 vs 23.5%, p = 1.00; respectively). Mortality at 2-year and 5-year follow-up was 16% and 25%, with no difference between the groups (log-rank p = 0.185 and 0.737, respectively). Conclusions: Patients with Heyde's syndrome had a high rate of bleeding requiring blood transfusion on admission, suggesting that is a severe disease with high mortality risk. No difference was found between the groups subjected to clinical treatment and to valve intervention with regard to rates of rebleeding and late mortality.

The patient was diagnosed with active rheumatic fever (RF), systemic lupus erythematosus (SLE) and Antiphospholipid syndrome (APS). The combination of three unusual diagnoses in the same patient makes this a unique case, modifying patient treatment and prognosis.
