Background

The prevalence of opportunistic infections in individuals with inflammatory bowel disease (IBD) remains relevant. Viral infections are a common cause of systemic inflammation of the digestive tract. Clinically expressed herpes and parvovirus infections are a serious problem, especially for people with prolonged immunosuppression. The aim of the study was

Methods

t:

o assess the incidence of certain herpes and parvovirus infections in patients with IBD.

Results

In total, 189 patients with IBD, 102 with ulcerative colitis and 87 with Crohn’s disease were examined. Of the number of patients: 98 women, 91man. The age of patients is from 16 to 63 years (mean age 41.4 ± 4.8). In addition to a standard examination, disease activity was assessed by indicators of highly sensitive C-reactive protein, homocysteine, vitamin D in blood serum, albumin in urine, calprotectin and lactoferrin in faeces. All patients underwent serological blood tests by ELISA for specific antibodies to herpes viruses and IgG/IgM antibodies to parvovirus B19, determination of DNA to herpes simplex viruses of types 1-2,6(HSV1-2?HSV6), Epstein–Barr (EBV}, cytomegalovirus (CMV), herpes zoster (HZV) by PCR in blood and mucosal biopsy, and also avidity.

Conclusion

Among patients with IBD, active infections (herpes and parvoviruses) in the blood occurred in 81 patients (42.8%); of them, 39 patients (20.6%) were diagnosed with monoherpesvirus infections, in 16 patients parvovirus (8.4%), and in 26 (13.8%) cases, active mixed viral infections were detected. In 79 cases (41.7%) of PCR biopsy material was positive for isolated infection: 36 cases (19%) of CMV, 21 cases (11.1%) of EBV, 22 cases (11.6%) of HSV6. Tissue viral infection was found in 34 patients (17.9%). Clinical endoscopic and laboratory indicators of activity in IBD were significantly higher in patients with active viral infections (p ˂ 0.05), which indicates the negative effect of chronic active herpes and parvovirus infections on the course of inflammatory bowel diseases. However, significant differences between patients with ulcerative colitis and Crohn’s disease were not detected.

The frequency of occurrence of herpes and parvovirus lesions in patients with IBD in the blood is more than 42.8%, isolated infection in the tissue in 41.7%, and mixed infection in 17.9% of the number of patients. The clinical endoscopic picture, as well as laboratory data indicate a more severe course of diseases in the presence of these infections.
