Osteoarticular disease is the most common complication of brucellosis in Western Iran. Sacroiliitis is the most common form of osteoarticular complication. With the use of a proper treatment regimen, the prospect for recovery is good.
We conclude that the DOX-STR combination should remain the first-line regimen for the treatment of brucellosis in our region; we recommend DOX-RIF and OFX-RIF combinations as the second-line regimens.
According to the results, tuberculosis patients still have a low quality of life in spite of receiving new care strategies. Therefore, enhancement in quality of life may improve adherence to anti-tuberculosis treatment, functioning and well-being of patients with tuberculosis.
The rapid increase of drug resistance and failure of available antibiotics to treat biofilm-associated infections is of great health concern. Accordingly, our study aimed to evaluate the synergistic antibacterial, biofilm inhibitory, and biofilm removal activities of melittin in combination with colistin, imipenem, and ciprofloxacin against multidrug-resistant (MDR) strong biofilm producer Acinetobacter baumannii isolates. The kinetics of biofilm formation were evaluated for the isolates for 144 h. Minimum inhibitory concentrations (MICs), minimum bactericidal concentrations (MBCs), minimum biofilm inhibitory concentrations (MBICs), and biofilm removal activities for melittin and combinations with antibiotics were determined. Inhibition of biofilm-associated protein (bap) expression by melittin was evaluated with real-time polymerase chain reaction (PCR). Field emission scanning electron microscopy (FE-SEM) was used to visualize the effect of synergism on the inhibition of biofilm production. The geometric means of the fractional inhibitory concentration index (FICi) for melittin-colistin, melittin-imipenem, and melittin-ciprofloxacin combinations were calculated as 0.31, 0.24, and 0.94, respectively. Comparing the geometric means of the removal activity for melittin, colistin, imipenem, and combinations of them in both 6 and 24 h showed a significant difference between the groups (p-value < 0.05). Exposure to melittin induced a statistically significant downregulation of bap mRNA levels in all isolates at sub-MIC doses. Analysis of the FE-SEM results demonstrated that the synergism of melittin-colistin at 0.125-0.25 μg inhibited biofilm formation completely. In conclusion, our findings indicate that melittin possesses considerable potential for use in combination with colistin and imipenem to treat infections caused by MDR strong biofilm producer A. baumannii isolates.
Given the fact that the ADR regimen had a higher efficacy and more rapid action in terms of relief of symptoms compared to the DR regimen, and that no significant difference in drug side-effects and disease relapse existed in the patients of either group, adding amikacin to the DR standard treatment regimen seems beneficial.
Despite the decreasing trend in hepatitis D virus (HDV) infection worldwide, the importance of this disease cannot be underestimated. The aim of this study was to evaluate patients positive for HBsAg with respect to HDV infection and related factors. Patients with chronic hepatitis B who presented at Hamedan Province Hepatitis Community Center in 2002-2007 were included. A questionnaire covering demographic variables and history of hepatic disease was completed for each patient. Necessary tests were performed and antibodies to HDV were measured using an enzyme-linked immunosorbent assay. Of 81 HBsAg positive patients, 14 (17.3%) contained anti-HDV IgG. Only one of the patients with anti-HDV IgM was positive for HBsAg. Of the anti-HDV IgG positive patients, two (14.3%) were women. Among the women examined in this study, 24 (35.8%) were anti-HDV IgG negative (p = 0.21), and of these, six (42.8%) were HBeAg positive while 17 (25.4%) of the anti-HDV IgG negative women were positive for HBeAg (p = 0.16). The prevalence of chronic hepatitis B among anti-HDV IgG positive and negative patients was 28.6% and 39.2% respectively (p = 0.31). Because of the relatively high rate of hepatitis B virus (HBV) and HDV co-infection in our study subjects, it is vital that healthcare providers and policy makers to recognize the risk factors associated with this HBV and HDV co-infection as well as the reasons for this increased anti-HDV serology in HBV carriers.
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.
