This study aims to evaluate immunization with polymeric microparticles containing recombinant antigen 85B (rAg85B) delivered directly to the lungs to protect against tuberculosis. rAg85B was expressed in Escherichia coli and encapsulated in poly(lactic-co-glycolic acid) microparticles (P-rAg85B). These were delivered as dry powders to the lungs of guinea pigs in single or multiple doses of homologous and heterologous antigens. Bacille Calmette-Guérin (BCG) delivered subcutaneously was employed as the positive control and as part of immunization strategies. Immunized animals were challenged with a low-dose aerosol of Mycobacterium tuberculosis (MTB) H37Rv to assess the extent of protection measured as reduction in bacterial burden (CFU) in the lungs and spleens of guinea pigs. Histopathological examination and morphometric analysis of these tissues were also performed. The heterologous strategy of BCG prime-P-rAg85B aerosol boosts appeared to enhance protection from bacterial infection, as indicated by a reduction in CFU in both the lungs and spleens compared with untreated controls. Although the CFU data were not statistically different from the BCG and BCG-BCG groups, the histopathological and morphometric analyses indicated the positive effect of BCG-P-rAg85B in terms of differences in area of tissue affected and number and size of granulomas observed in tissues. P-rAg85B microparticles appeared to be effective in boosting a primary BCG immunization against MTB infection, as indicated by histopathology and morphometric analysis. These encouraging observations are relevant to boosting adults previously immunized with BCG or exposed to MTB, commonly the case in the developing world, and should be followed by further assessment of an appropriate immunization protocol for maximum protection.

OBJECTIVESTo evaluate the effect of amine ratio (ethyl 4-dimethylaminobenzoate, EDMAB) on the maximum rate of polymerization (R(p)(max)), degree of conversion (DC), Knoop hardness (KH), water sorption (Wsp), water solubility (Wsl) and color changes (DeltaE) over time of resin composites formulated with the photoinitiators camphorquinone (CQ), phenylpropanedione (PPD) and CQ-PPD in combination.MATERIALS AND METHODSExperimental resin composites were made with photoinitiator:amine ratios of 2:1, 1:1, 1:1.5 and 1:2 by weight. R(p)(max) was evaluated with differential scanning calorimetry (DSC), DC with DSC and Fourier transformed infrared (FTIR) spectroscopy, KH with Knoop indentation, Wsp and Wsl adapted from ISO 4049; and color with a chromameter. The results were analyzed with two-way ANOVA/Tukey's multiple comparison test (p<0.05).RESULTSThe higher the amine ratio in the composite, the higher was DC, R(p)(max), and KH, and the lower was Wsl, regardless of the photoinitiator type. The use of PPD alone resulted in poorer properties than CQ and CQ-PPD. Many factors seem to affect the color changes and the b-axis data revealed that the higher the amine ratio, the higher was the +b value (yellowing) for CQ and CQ-PPD formulations.CONCLUSIONSHigher amine ratios led to improved polymer properties, but also produced more yellowing in resin composites with CQ and CQ-PPD. The use of PPD alone was not advantageous for producing good final properties when compared to CQ and CQ-PPD.

Setting a New Standard for Topical Therapy of Upper-Tract Transitional-Cell Carcinoma: BCG and Interferon-α2B

BACKGROUND AND PURPOSEWe report our office-based technique and results of BCG and interferon-alpha2B (BCG-IFN) for upper-tract transitional-cell carcinoma (TCC).TECHNIQUEPapillary lesions were ablated endoscopically after biopsy. Office flexible cystoscopy was performed, and a 0.038-inch guidewire or Glidewire was advanced into the renal pelvis. A 5F ureteral catheter was placed over the wire, and a free flow of urine was confirmed. Half-strength BCG + 50 million units of IFN was infused under low pressure for 1 hour. The ureteral catheter was removed, and patients were instructed to void 1 hour later.RESULTSBetween 2000 and 2006, 10 patients with a median age of 72 years were treated with BCG-IFN for upper-tract TCC in 11 renal units. Follow-up ureteroscopy with or without biopsy was performed after a 6-week induction to evaluate response. Complete responders were placed on a maintenance regimen. With a median follow-up of 24 months, 8 patients (80%) demonstrated a complete response (CR) to therapy, and 2 had a partial response (decrease in tumor size, number, or both). Six patients with a CR have continued on maintenance therapy. There were no side effects or complications with the instillation therapy.CONCLUSIONWe describe a safe, minimally invasive, and effective office-based technique for upper-tract BCG-IFN instillation.
