[E.coli bacterial suspension in the treatment of hemorrhoids]. / Vozmozhnosti ispol'zovaniya preparatov suspenzii kul'tury bakterii E.coli v lechenii gemorroya v svete sovremennykh kontseptsii.

Hemorrhoidal disease is the most common proctologic disease and the search for new treatment methods, as well as an in-depth understanding of the mechanisms underlying effects of well-known agents on disease pathogenesis still remain relevant. There have been long recognized the effects of the E.coli bacterial culture suspension (BCS) as a therapeutic means eliciting decreased exudation during inflammation, wound healing, tissue regeneration, and stimulated immunity. Here, based on recent findings related to innate and adaptive immune cells, we set out to present mechanisms accounting for some effects coupled to commensal bacteria, particularly inactivated E.coli BCS, which are important for understanding pathogenesis-related action of drug Posterisan and Posterisan forte, and outline their broad application in therapy of hemorrhoids. Based on the analysis, it was concluded that such effects are mediated via multi-pronged and complementary interactions between diverse human receptors expressed in the anorectal region cells and microbial components: NOD ligands, metabolites, enzymes, heat shock proteins and nucleic acids, which lead to production of pro-inflammatory cytokines by anodermal colonocytes, innate and adaptive immune cells, neurons in the submucosal plexus covered by transitional zone epithelium, and hemorrhoid plexus endothelium. Based on current concepts, it may be plausible that E.coli BCS-derived biologically active components contained in drug Posterisan are capable of exerting both positive local and systemic effects, which extend our understanding and substantiate its use in hemorrhoidal disease. The effectiveness of using Posterisan and Posterisan forte is corroborated by their indications in real-life clinical practice, both as a conservative therapy as well as after surgical interventions.

Prevalence and Association of Mycobacterium avium subspecies paratuberculosis with Disease Course in Patients with Ulcero-Constrictive Ileocolonic Disease.

BACKGROUND: Association of Mycobacterium avium subspecies paratuberculosis (MAP) and Crohn's disease (CD) has been controversial due to contradictory reports. Therefore, we determined the prevalence of MAP in patients with CD and intestinal tuberculosis (ITB) and its association with clinical course. METHODOLOGY: Blood and intestinal biopsies were taken from 69 CD, 32 ITB patients and 41 patients with haemorrhoidal bleed who served as controls. qPCR targeting of MAP-specific IS900 gene was used to detect the presence of MAP DNA. qPCR results were further validated by sequencing. Immunohistochemistry (IHC) was used to detect the presence of MAP antigen in biopsy specimens. CD and ITB patients were followed-up for disease course and response to therapy. PRINCIPAL FINDINGS: The frequency of MAP-specific DNA in biopsies by qPCR was significantly higher in CD patients (23.2%, p = 0.03) as compared to controls (7.3%). No significant difference in intestinal MAP presence was observed between ITB patients (12.5%, p = 0.6) and controls (7.3%). MAP presence in blood of CD patients was 10.1% as compared to 4.9% in controls while no patients with ITB were found to be positive (p = 0.1). Using IHC for detection of MAP antigen, the prevalence of MAP in CD was 2.9%, 12.5% in ITB patients and 2.4% in controls. However, long-term follow-up of the patients revealed no significant associations between clinical characteristics and treatment outcomes with MAP positivity. CONCLUSION: We report significantly high prevalence of MAP in intestinal biopsies of CD patients. However, the presence of MAP does not affect the disease course and treatment outcomes in either CD or ITB patients.

Effect of fermented milk containing Lactobacillus casei strain Shirota on constipation-related symptoms and haemorrhoids in women during puerperium.

Constipation and haemorrhoids are common complaints after childbirth. The objective of this pilot study was to evaluate impact of fermented milk containing Lactobacillus casei strain Shirota (LcS) on stool consistency and frequency, constipation-related symptoms and quality of life, and incidence of haemorrhoids in women during puerperium. Forty women who had natural childbirth were randomised to group consuming either one bottle/day of fermented milk containing at least 6.5×109 cfu of LcS, or placebo, for 6 weeks after childbirth. Subjects filled in a diary on their bowel habits including number of bowel movement, stool consistency and incidence of haemorrhoids, and answered questionnaires on constipation-related symptoms (PAC-SYM) and quality of life (PAC-QOL) during the study period. The probiotic group showed the better scores on overall PAC-SYM (P=0.013), PAC-SYM subscales of abdominal symptoms (P=0.043) and rectal symptoms (P=0.031), and PAC-QOL satisfaction subscale (P=0.037) in comparison with the placebo group. In the probiotic group, two to four subjects experienced haemorrhoids during the first 3 weeks of treatment. The number decreased in week 4 and no one had haemorrhoids on most days in week 5-6. In the placebo group, on average four subjects had haemorrhoids from the beginning, and no obvious change was observed until week 6. No statistically significant effect was observed on stool consistency and frequency. The study products did not cause any adverse event in the subjects. Results of this study indicate that continuous consumption of fermented milk containing LcS might alleviate constipation-related symptoms, provide satisfactory bowel habit and result in earlier recovery from haemorrhoids in women during puerperium. Nonetheless, there are several limitations in interpretation of the results attributed to the study design, including lack of baseline data. Further study is required in order to confirm the efficacy.

[The use of methyldioxyline for the prevention of local complications following hemorrhoidectomy]. / Primenenie metildioksidina dlia profilaktiki mestnykh oslozhnenii posle gemorroidéktomii.

The article discusses the results of clinico-laboratory study of the application of methyl dioxyline ointment after hemorrhoidectomy with complete restoration of the anal canal mucosa. It is shown that the ointment is a reliable measure for the prevention of postoperative purulent complications, it improves the reparative processes. Its use in the treatment of wounds developing as the result of excision of hemorrhoids shortens the term of in-patient treatment after the operation and the period of general incapacity.

Intraepithelial neoplasia of the anal canal in hemorrhoidal tissue: a study of 19 cases.

The investigators report the clinical and pathologic features of 19 cases of intraepithelial neoplasia occurring in the anal canal mucosa of routinely excised hemorrhoidal tissue, a condition that has been infrequently described. The patients were 12 women and seven men having an age range of 21 to 74 years (mean, 48 years). Two patients had coexistent anogenital condylomata acuminata. Leukoplakia of the hemorrhoidal surface was noted in two patients. Intraepithelial neoplasia arose in the transition zone of the anal canal of 11 cases, in the squamous zone of three cases, and in both sites of five cases. All were high-grade intraepithelial neoplasms; one was classified moderate to severe dysplasia, 17 exhibited severe dysplasia/carcinoma in situ, and one contained microinvasive carcinoma. Both keratinizing and cloacogenic type neoplasms were observed. Associated koilocytotic atypia was identified in 16 cases (84%). In situ hybridization for human papillomavirus (HPV) messenger RNA demonstrated HPV RNA sequences in seven of nine neoplasms (78%) studied by that technique (five HPV type 16, one HPV type 18, and one coinfection with HPV types 6 and 18). Eighteen patients had no clinically evident recurrent or progressive disease at mean follow-up of 6.6 years. Residual/recurrent intraepithelial neoplasia was noted in one patient at 1, 2, 5, and 49 months posthemorrhoidectomy. Our data indicate that incidentally discovered high-grade intraepithelial neoplasia present in hemorroidal tissue is a clinically nonaggressive lesion frequently associated with HPV infection. Hemorrhoidectomy alone is curative in most cases.

Hemorrhoidal banding. A warning.

Band ligation of symptomatic internal hemorrhoids is a well-established and accepted outpatient procedure. The purpose of this paper is to alert the medical profession to potential complications and death following this procedure. Each of the four patients described in this report experienced pain and inability to urinate following banding. This report does not condemn banding but, rather, focuses on problems associated with a procedure perceived by many to be risk free.
