RESUMO
Objective:To investigate the clinical features of amoebic enteritis with acquired immunodeficiency syndrome (AIDS) patients.Methods:The clinical data of patients diagnosed of amoebic enteritis in Beijing Ditan Hospital, Capital Medical University from April 2011 to October 2019 were collected. They were divided into amoebic enteritis group and amoebic enteritis with AIDS group. The laboratory indexes, pathological examination and colonoscopic appearance of the two groups were analyzed retrospectively. The clinical characteristics of amoeba enteritis with AIDS patient were summarized. Pearson chi-square test, continuous calibration chi-square test, Fisher′s exact test, independent sample t test and Mann-Whitney U test were used for statistical analysis. Results:A total of 53 patients with amoebic enteritis were included, including 31 cases in amoebic enteritis group and 22 cases in amoebic enteritis with AIDS group. The detection rate of amoebic trophozoite in cases feces in amoebic enteritis with AIDS group was lower than that in amebic enteritis group (68.2%(15/22) vs 96.8%(30/31)) with statistical significance ( χ2=6.13, P=0.013). The detection rate of amoebic trophozoite by colonoscopy in amoebic enteritis with AIDS was higher than that in amebic enteritis group (7/15 vs 1/16) with statistical significance (Fisher′s exact test, P=0.015). Amoebic enteritis with AIDS cases had lower levels of red blood cell count ((3.48±0.80)×10 12/L vs (4.11±0.81)×10 12/L), hemoglobin ((102.40±25.74) g/L vs (121.52±22.73) g/L), albumin ((29.07±5.94) g/L vs (35.48±6.92) g/L), CD4 + T-lymphocyte counts (76.00 (26.25, 228.50)/μL vs 514.50 (444.00, 752.25)/μL) than patients with amoebic enteritis, which were all statistically significant ( t=2.80, 2.86, 3.52 and Z=-5.27, respectively, all P<0.050). And amoebic enteritis with AIDS cases had higher level of alanine aminotransferase (ALT) (21.00 (12.85, 41.33) U/L vs 13.40 (9.40, 22.40) U/L, Z=-2.32, P=0.020). The results of colonoscopy showed that amoebic enteritis with AIDS cases had higher rate of intestinal mucosa ulcer than amoebic enteritis cases ((11/15 vs 5/16) Fisher′s exact test, P=0.032). Conclusions:Amoebic enteritis with AIDS cases have lower levels of red blood cells, hemoglobin, albumin and CD4 + T-lymphocyte counts and higher levels of ALT. Amoebic enteritis with AIDS cases have higher rate of intestinal mucosa ulcer detected by colonoscopy. Colonoscopy combined with biopsy play an important role in the diagnosis of amoebic enteritis with AIDS patients.
