No difference in outcome was observed in patients with metastatic renal-cell carcinoma who were treated with interferon gamma-1b as compared with placebo. These results emphasize the necessity of testing the efficacy of immunomodulators in randomized studies.

Objective: The purpose of this study was to evaluate the impact of diabetes and periodontal disease in us-CRP, an inflammatory marker in patients with and without acute myocardial infarction (AMI). Subjects and methods: A case-control study was conducted in 401 subjects aged between 30 and 75 years, living in Bogotá D.C. (Colombia). Patients arriving at the emergency room of the San Ignacio University Hospital with AMI were included into the case group. The control group was defined as those subjects without AMI. The following blood tests were performed: complete blood count (CBC), glycemia, total cholesterol, triglycerides, cHDL, cLDL, and us-CRP. Patients with infections or antibiotic treatment within the last three months, who had received periodontal treatment within the six months prior to the study entry, had oral ulcerations, or less than seven teeth were excluded from the study. Periodontal disease was diagnosed based on the 1999 Armitage's classification. Results: The mean us-CRP value found in diabetic patients with severe chronic periodontitis was 5.31 mg/L (SD 6.82), and 2.38 mg/L (SD 4.42) in non-diabetic patients, being statistically significant (p = 0.000). Conclusion: Diabetes had an impact in periodontal disease and us-CRP. In patients with AMI, DM and PD considerably increased the us-CRP.

Sujeitos e métodos: Um estudo caso-controle foi conduzido em 401 sujeitos com idades entre 30 e 75 anos que moravam em Bogotá D.C. (Colômbia). Os pacientes que chegavam ao pronto--socorro do hospital universitário de San Ignacio com IAM foram incluídos no grupo caso. O grupo controle foi definido por sujeitos sem IAM. Foram feitos os seguintes exames de sangue: contagem total de eritrócitos (CTE), glicemia, colesterol total, triglicérides, cHDL, cLDL e us-CRP. Os pacientes com infecções ou em tratamento com antibióticos nos últimos três meses, que receberam tratamentos periodontal nos seis meses anteriores ao estudo, tinham úlceras orais ou menos de sete dentes foram excluídos do estudo. A classificação de Armitage de 1999 foi usada para definir a doença periodontal. Resultados: O valor médio de us-CRP observados em pacientes diabéticos com periodontite crônica grave foi 5,31 mg/L (SD 6,82) e 2,38 mg/L (SD 4,42) em pacientes não diabéticos, um valor estatisticamente significativo (p = 0,000). Conclusão: O diabetes tem um impacto na doença periodontal e na us-CRP. Em pacientes com IAM, DM e DP, a us-CRP foi consideravelmente mais alta.
