A proposta deste trabalho foi identificar a presença de microrganismos superinfectantes (bastonetes entéricos Gram-negativos e Candida sp.) em pacientes transplantados cardíacos e correlacioná-la com a presença de crescimento gengival. Foram examinados 30 pacientes (10 mulheres e 20 homens - média de idade: 45 anos). Todos os pacientes estavam sob terapia com ciclosporina-A (CsA) sem terem sido submetidos a antibioticoterapia e nem a tratamento periodontal prévio, por pelo menos três meses antes do início do estudo. O paciente deveria ter, no mínimo, seis dentes. Foram registrados os índices de placa bacteriana (IP), índice gengival (IG), valores de profundidade clínica de sondagem (PCS) e nível clínico de inserção (NCI). Análise microbiológica foi realizada a partir de amostras coletadas de sulco/bolsa gengival (s/b) e da saliva estimulada (se). Os pacientes foram divididos em dois grupos: com crescimento gengival (CCG) e sem crescimento gengival (SCG). Após análise estatística (teste do qui-quadrado; teste t de Student; prova exata de Fisher; p < 0,05), concluiu-se que não houve diferença entre os dois grupos de pacientes com relação a sexo dos pacientes, dosagem de CsA, tempo decorrido após o transplante, IP, IG, PCS e NCI. O exame microbiológico das amostras coletadas mostrou a ausência de bastonetes entéricos Gram-negativos. Foi possível a detecção de Candida sp. (s/b-30% e se-30%). Na amostra de saliva estimulada a presença desse microrganismo estava associada aos pacientes SCG.
The aim of this study was to identify the presence of superinfecting microorganisms (Gram-negative enteric rods and Candida sp.) in heart transplant patients and correlate this with gingival overgrowth. Thirty patients (10 females, 20 males - mean age 45 years) were examined. All were under cyclosporin-A (CsA) therapy. Patients who had taken any antibiotics 3 months prior the study or had been submitted to periodontal therapy were not enrolled. Patients were required to have at least 6 teeth. The plaque index (PI), gingival index (GI), pocket depth (PD) and clinical attachment level (CAL) were recorded. Microbiological samples were taken from sulcus/pocket (s/p) and from stimulated saliva (ss) and submitted to analysis. Patients were divided into two groups: the ones with gingival overgrowth (GO) and those without gingival overgrowth (WGO). After statistical analysis (chi-square test, Student's t-test, Fisher test, p < 0.05), we concluded that there was no statistical difference between groups in the parameters of gender, CsA dosage, time since transplantation, PI, GI, PD and CAL. Gram-negative rods from either the sulcus/pocket or saliva samples were not found. Candida sp. was detected (s/p - 30% and ss - 30%). Stimulated saliva samples analysis determined that the presence of Candida sp. was associated with patients without gingival overgrowth.
