“…45 Indeed, FZD is reported as a mutagenic, genotoxic and potentially carcinogenetic. 46,47 However, MTZ is also listed as a potential carcinogen by FDA and yet it is commonly used worldwide. 45 The sensitivity of H. pylori to furazolidone seems to vary from one geographical region to another.…”

“…Studies suggested that irreversible damage to the DNA of human epithelial cells (HEp-2) as well as hormone disturbances (reflecting endocrine dysfunction) occurred prevalently when cells were exposed to furazolidone (De Angelis et al, 1999;Ahmed et al, 2008). The majority of the information available describes in vivo studies which utilise mouse and rat models for examination of the effects of furazolidone and mainly nitrofurazone or its residue semicarbazide.…”

Nitrofuran antibiotics, employed for the treatment of bacterial diseases in livestock production, were banned from use in the European Union (EU) in 1995 due to concerns about the carcinogenicity of their residues in edible tissue. This review provides an overview of nitrofuran toxicity, metabolism, and also specific aspects of legislation surrounding their prohibition. Special attention is devoted to semicarbazide -a nitrofuran metabolite and food contaminant. Analytical procedures for nitrofuran analysis in various matrices and validation requirements for screening and confirmation methods with respect to EU regulations are also reviewed.Keywords: nitrofurans; tissue bound metabolites; semicarbazide; bioavailability; mutagenicity; legislation; sample preparation; validation; detection methods List of abbreviations AHD = 1-aminohydantoin; AOZ = 3-amino-2-oxazolidinone; AMOZ = 3-amino-5-morpholino-methyl-1,3-oxazolidinone; CC α = decision limit; CC β = detection capability; EC = European Commission; EFSA = European Food Safety Authority; ELISA = enzyme linked immuno-adsorbent assay; ESI = electro-spray ionisation; EU = European Union; FTD = furaltadone; FZD = furazolidone; HPLC = high performance liquid chromatography; IC = inhibition concentration; LC = liquid chromatography; LOD = limit of detection; MS = mass spectrometry; NFT = nitrofurantoin; NFZ = nitrofurazone; NP = nitrophenyl; NPAHD = 3-(2-nitrobenzylidenamino)-2,4-imidazolidinedione); NPAMOZ = 5-(morpholinomethyl)-3-(2-nitrobenzylidenamino)-2-oxazolidinone); NPAOZ = [3-(2-nitrobenzylidenamino)-2-oxazolidinone]; NPSEM = 3[(2-nitrophenyl)methylene]-hydrazinecarboxamide; o-NBA = ortho-nitrobenzaldehyde; RASFF = Rapid Alert System for Food and Feed; SE = solvent extraction; SEM = semicarbazide; SPE = solid phase extraction; UV = ultraviolet

Background/Aim:Furazolidone-based therapies are used in developing countries to cure Helicobacter pylori infection due to its low cost. The low bacterial resistance toward furazolidone may render appealing the use of this drug even in developed countries. However, some relevant safety concerns do exist in using furazolidone.Patients and Methods:This was a systematic review with pooled-data analysis of data regarding both eradication rate and safety of furazolidone-based therapies for H. pylori infection. Intention-to-treat (ITT) and per-protocol (PP) eradication rates were calculated.Results:Following furazolidone-based first-line therapy, H. pylori eradication rates were 75.7% and 79.6% at ITT and PP analysis, respectively (P<0.001). The overall incidence of side effects and severe side effects were 33.2% and 3.8%, respectively. At multivariate analysis, only high-dose furazolidone was associated with increased therapeutic success (OR: 1.5, 95% CI: 1.3-2.7; P<0.001), while occurrence of side effects was relevant following treatment for a long duration (OR: 2.9, 95% CI: 2.2-4.1; P<0.001), high-dose furazolidone (OR: 2.3, 95% CI: 1.7-3.2; P<0.001) and bismuth-containing regimens (OR: 2.1, 95% CI: 1.5-2.8; P<0.001).Conclusions:Furazolidone-based regimens usually achieve low eradication rates. Only a high-dose regimen improves the cure rate, but simultaneously increases the incidence of severe side effects. Therefore, we suggest that patients have to be clearly informed about the possible genotoxic and carcinogenetic effects for which furazolidone use is not approved in developed countries.
