Abstract

From 180 patients infected with human immunodeficiency virus (HIV) and followed-up for one year, 17 cases (9.44%) were referred to detect oesophageal pathology. They were prospectively analyzed through fibroscopy, radiology, biopsies for histopathology, virology and mycology and brush cytology. Most frequent symptoms were dysphagia. Odynophagia and retrosternal pain, usually associated, and not providing an accurate diagnostic clue. The most common causes of symptoms were oesophageal candidiasis (47.70%), and herpetic ulcers (23.52%) caused by herpes simplex virus (HSV) type 2. Reflux pathology was also found (11.76%). Cytomegalovirus, other opportunistic infections and tumors were not detected. Seven (64%) of the eleven patients with oesophageal candidiasis also had oral involvement. Four (66%) of six oesophageal ulcers were herpetic; two of them (50%) showed oral ulcers too, and one (25%) had perioral herpetic blisters. Almost in every case endoscopic features allowed diagnosis. Endoscopy in candidiasis showed isolated or confluent white plaques of variable grade. Herpetic ulcers, alone or multiple, were deep with slightly elevated borders. Radiology yielded a poor diagnostic profit (50%), specially in case of multiple lesions. Cytology was highly specific and sensitive (both 90.9%) and suggested viral etiology in 100% of HSV patients. Histopathology was less sensitive than endoscopy and cytology (73% in candida and one HSV non-ulcer case). Both, cytology and histopathology showed koilocytosis in herpetic virus infected patients. The studies performed allowed to change the HIV disease stage in ten patients (62.5%) and to diagnose AIDS in seven (43.75%). In every case medical behavior was oriented or changed by these studies.

PIP: 16 HIV seropositive patients among the 180 treated at the Hospital Muniz and the Hospital Posadas in Buenos Aires between December 1988 and December 1989 were referred to the Hospital Posadas Endoscopy Service for esophageal studies. The 16 patients were prospectively studies by means of fiberoscopy, radiology, biopsies, virology, mycology, and brush cytology. Early treatment is of utmost importance because opportunistic infections may aggravate the general condition, increase immune system effects, and probably permit greater replication of HIV, in addition to producing symptoms. 14 patients were male and 2 female. Ages ranged from 18 to 41 and averaged 32 years. 10 were male homo- or bisexuals and the other 6 were intravenous drug users. 14 of the patients consulted because of specifically esophageal symptoms. 12 reported dysphagia, 8 odynophagia, and 6 retrosternal pain. 9 patients presented various symptoms. 15 of the 16 symptomatic patients had some pathology related to HIV. The remaining case presented a small submucus tumor and gastroesophageal reflux. The symptoms had appeared between 10 days and 1 year prior to study. Symptoms did not provide accurate diagnostic clues. 11 cases of esophageal candidiasis were diagnosed endoscopically by isolated or confluent white plaques. 3 patients classified as grade 1 or 2 on the basis of the intensity and density of plaques had mild symptoms, and 8 classified as grade 3 or 4 had more severe symptoms. 7 of the 11 patients also had oral candidiasis. 4 of 6 patients presenting ulcerative pathology were diagnosed virologically with herpes simplex virus type 2. Herpetic ulcers were single or multiple and were deep with slightly raised edges. No ulcers attributable to cytomegalovirus were diagnosed. 4 of the 11 patients with candidiasis also had ulcers, in 2 cases herpetic. The studies indicated a change in the stage of HIV infection following Centers for Disease Control criteria in 10 cases. AIDS was diagnosed in 7 cases based on esophageal findings. Endoscopic study and the samples obtained guided treatment in the 16 patients. In 1 case a repeat endoscopy led to a change in treatment. It is recommended that endoscopy be performed in all patients with esophageal symptoms. Radiology was relatively ineffective, with 50% of diagnoses in error. Histopathology required multiple biopsies and was less sensitive than endoscopy and cytology. Cytology was highly specific and sensitive.
