Achalasia is not associated with measles or known herpes and human papilloma viruses.

Abstract:

:Achalasia is an esophageal motility disorder of unknown etiology. Several studies suggest possible herpes or measles virus etiology, but results are inconclusive. The aim of this study was to test whether herpesvirus (HV), measles (MV), or human papilloma virus (HPV) sequences could be detected in myotomy specimens from a wide spectrum of achalasia patients, using the polymerase chain reaction (PCR) technique. Myotomy specimens from 13 achalasia patients, esophagectomy specimens from nine esophageal cancer patients, and autopsy specimens from six fetuses were studied with the PCR technique. Paired oligonucleotide primers of HV (HSV-1 and 2, CMV, EBV, VZV, and HHV-6), MV and HPV sequences and exon 3 of the HPRT gene were used for the PCR DNA amplification. Amplified products were resolved on agarose gels and stained with ethidium bromide. All specimens yielded the appropriate-sized products for exon 3 of the HPRT and viral controls. No amplified products were seen in the achalasia specimens or controls corresponding to any of the virus sequences tested. The absence of HV, MV, and HPV sequences suggests that these viruses are not associated with achalasia but does not exclude the possibility of a previously unidentified virus as a causal agent. Further studies aimed at identifying an unknown viral agent as a cause for achalasia are warranted.
