Herpetic infections are common complications in AIDS patients. The clinical features could be uncommon and antiviral chemotherapy is imperative. A rapid diagnosis could prevent incorrect approaches and treatment. The polymerase chain reaction is a rapid, specific and sensible method for DNA amplification and diagnosis of infectious diseases, especially viral diseases. This approach has some advantages compared with conventional diagnostic procedures. Recently we have reported a new PCR protocol to rapid diagnosis of herpetic infections with suppression of the DNA extraction step. In this paper we present a case of herpetic whitlow with rapid diagnosis by HSV-1 specific polymerase chain reaction using the referred protocol.
As infecções herpéticas são complicações comuns em pacientes com AIDS. As manifestações clínicas podem ser incomuns e o tratamento antiviral é imperativo. Um método diagnóstico rápido pode previnir abordagens e tratamentos incorretos. A reação em cadeia da polimerase (PCR) é um método rápido, sensível e específico para a amplificação de DNA e para o diagnóstico de doenças infecciosas, especialmente as de etiologia viral. Esta abordagem tem vantagens quando comparada com os métodos convencionais de diagnóstico virológico. Recentemente nós relatamos um novo protocolo de PCR para o diagnóstico rápido de infecções herpéticas com supressão da etapa de extração de DNA. Neste trabalho nós apresentamos um caso de paroníquea herpética com diagnóstico através de PCR específico para Herpes Simplex tipo 1 usando o referido protocolo
