These patients with reactive arthritis did extremely well on the regimen described. In our study group, the number of patients and the number of samples with positive findings of bacteria or their DNA were lower after the antibiotic treatment combined with surgery, although not all bacteria were eradicated. Adverse effects of prolonged azithromycin administration were insignificant. This open treatment approach is recommended but does need a study with controls.
Reiter's syndrome is a multisystem disease, predominantly occurring in human leukocyte antigen B27 positive young males. The fact that the causative agents are found in the synovial membrane or synovial fluid is indicative of infectious rather than reactive arthritis.
Postvenereal reactive arthritis is an inflammatory form of arthritis that commonly develops after urogenital infection, predominantly in human leucocyte antigen-B27-positive men in the third decade of life. In our hospital, patients underwent synovectomy before a 4-month course of antibiotics (ciprofloxacin, tetracycline and roxithromicin). The clinical remission was achieved in approximately 70% patients. At molecular level, the remission was associated with the negative polymerase chain reaction findings of bacteria.
Background: The effect of aflatoxin B1 (AFB1) administration on expression of genes coding for acute-phase proteins, and nuclear protooncogenes c-fos and c-jun, and alpha-fetoprotein gene has been studied in rats. Methods: AFB1 was administered to male Albino Oxford (AO) rats as a single intraperitoneal dose (1 mg/kg body weight). The expression of genes for albumin, cystein protease inhibitor, fibrinogen, haptoglobin, a1-acid glycoprotein and for c-Fos, c-Jun and alpha-fetoprotein in rat liver was measured by Northern hybridization. Results: The mild increase in the levels of mRNA for acute-phase proteins after AFB1 administration was observed during the first 24 hours. The exceptions were the mRNA levels in liver for cystein protease inhibitor, which were 50%, decreased as compared to the control values. In addition, mild increase of the expression of c-fos protooncogene with two peaks were noted at three (1.3 fold) and 72 hours (1.5 fold) after injection AFB1 to rats. The expression of nuclear protooncogene c-jun at 1 hour and 72 hour after acute poisoning was 2.6 fold and 3.7 fold increased as compared to control values, respectively. The mRNA levels in liver for the alpha-fetoprotein reached a maximum at 1 hour after AFB1 injection and it was 1.8 times higher than the levels in the livers of nontreated animals. Conclusion: Single administration of AFB1 induced increased transcription of c-jun and c-fos genes while typical acute-phase response was not found
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
