The present invention relates to methods of treating a subject with a lysosomal disorder, by administering an agent for enzyme replacement therapy and an agent for anti-TNF-&#x3b1; therapy; by administering a pentosan polysulfate therapy; or by administering a substrate reduction therapy and an anti-TNF-&#x3b1; therapy. The invention further relates to a method of reducing inflammatory cytokines in a subject with a lysosomal disorder that is being treated by enzyme replacement therapy, by administering an agent for anti-TNF-&#x3b1; therapy.

Anti-TNF-&#x3b1; therapy for the mucopolysaccharidoses and other lysosomal disorders

Oral pentosan polysulfate (PPS) compositions treat diseases such as diabetes, inflammation, atherosclerosis. The compositions are also effective in reducing matrix metalloproteinases (MMPs).

Inhibition of TNF-&#x3b1; induced activation of NFKB by pentosan polysulfate

The present invention relates generally to the non-enzymatic glycosylation of amyloidogenic proteins and the consequent formation of advanced glycosylation endproducts (AGEs). It has been found that formation of AGE-amyloidogenic proteins can enhance amyloidosis. The invention further relates to compositions and methods for the prevention and treatment of amyloidosis associated with amyloid diseases, particularly neurodegenerative disease and Type II diabetes, and more particularly Alzheimer's disease. In a specific example, aggregation of an amyloidogenic peptide, &bgr;AP, is enhanced by the glycosylation reaction of &bgr;AP to form AGE-&bgr;AP as defined herein. Accordingly, the invention extends to a method for modulating the in vivo aggregation of amyloid polypeptides and associated amyloidosis by controlling the formation and presence of AGE-amyloid polypeptide. A corresponding diagnostic utility comprises the measurement of the course and extent of amyloidosis by a measurement of the presence and amount of AGEs and particularly, AGE-amyloid. An assay is included that may use the AGE-amyloid polypeptide of the present invention to identify disease states characterized by the presence of AGE-amyloid. Additionally, such an assay can be utilized to monitor therapy and thus adjust a dosage regimen for a given disease state characterized by the presence of AGE-amyloid.

Compositions and methods for advanced glycosylation endproduct-mediated modulation of amyloidosis

Methods are provided for measuring the accumulation of advanced glycosylation endproducts (AGEs), and for lowering the accumulation of advanced glycosylation endproducts, which are predicated on the discovery that such AGEs and their precedent glycotoxins are present in tobacco and its byproducts. More particularly, the methods focus on the observation that individuals who smoke or otherwise use tobacco have increased levels of AGEs relative to non-smoking individuals. The present methods relate to the measurement of AGE levels in both individuals and in tobacco and its byproduct, smoke, and to the treatment of such individuals with agents capable of reacting with glycosylation products to either avert or diminish the accretion of AGEs in the body. Methods are also provided for the evaluation of the tobacco products to determine their storage status and organoleptic capacity and potential, for the treatment of the ambient atmosphere to lower AGE levels, and for the treatment of the tobacco products and combustion byproducts to lower AGE levels therein. For example, air or other samples may be taken and evaluated by a dosimeter or like device, to determine whether AGE levels exceed normal, after which measures could be implemented to remediate the ambient condition. Likewise, filters and similar devices for removing AGEs from tobacco smoke are provided. All such methods and corresponding materials are contemplated and included.

Methods for treatment predicated on the presence of advanced

The present invention is directed to methods for detecting the presence of advanced glycosylation endproducts using the unexpected discovery that certain antibacterial proteins, in particular lysozyme and lactoferrin, bind to advanced glycosylation endproducts (AGEs) with high affinity, and that this binding activity is substantially noncompetitive with binding of bacterial carbohydrates to the antibacterial proteins. Accordingly, the invention relates to diagnostic methods for diseases and disorders associated with increased levels of AGEs, by using compositions having associated therewith a molecule having a hydrophilic loop domain, which domain is associated with AGE-binding activity, and compositions comprising such a domain. The invention further relates to compositions and devices for partitioning AGEs away from a sample.

The in vivo oxidation of lipids and lipid-containing molecules has been discovered to be initiated by the concurrent reaction of such lipid materials with reducing sugars such as glucose, advanced glycosylation endproducts such as AGE-peptides, or a compound which forms advanced glycosylation endproducts, to form materials or particles known as AGE-lipids. AGE-lipids have been implicated in the aging process, the abnormal formation of lipofuscin and in various disease states such as diabetes and atherosclerosis. Diagnostic methods are contemplated, extending in utility from the detection of the onset and course of conditions in which variations in lipid oxidation, AGE-lipid levels, LDL levels, apolipoprotein levels, apolipoprotein receptor binding the like, may be measured, to drug discovery assays. Corresponding methods of treatment and pharmaceutical compositions are disclosed that are based on an active ingredient or ingredients that demonstrates the ability to modulate the levels of all of the foregoing markers of lipid oxidation.
