A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and / or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration.

A pharmaceutical composition comprising as a first active ingredient an estrogen, such as estradiol or estradiol valerate, in sufficient amounts to treat disorders and symptoms associated with deficient endogenous levels of estrogen in women, and as a second active ingredient 6beta,7beta; 15beta; 16beta-dimethylene-3-oxo-17alpha-preg-4-ene-21,17-carbolactone (drospirenone, DRSP) in sufficient amounts to protect the endometrium from the adverse effects of estrogen is useful for, amongst others, treating peri-menopausal, menopausal and post-menopausal women. This composition may be used for hormone replacement therapy and may be administered as a multi-phased pharmaceutical preparation. This combination therapy may comprise continuous, sequential or interrupted administration, or combinations thereof, of DRSP and estrogen, each optionally in micronized form.

This invention provides various combinations of enzyme replacement therapy, gene therapy, and small molecule therapy for the treatment of lysosomal storage diseases.

A multichannel infusion system for use with a hemofilter includes first and second measurement devices that measure the weight of a replacement fluid in a first receptacle and an ultrafiltrate in a second receptacle, a first pumping module configured to accept a first desired flow rate and deliver the replacement fluid from the first receptacle to the hemofilter at the accepted first desired flow rate, a second pumping module configured to accept a second desired flow rate and remove the ultrafiltrate from the hemofilter to the second receptacle at the accepted second desired flow rate, and a control system in communication with the first and second measurement units and the first and second pumping modules. The control system is configured to adjust the first and second desired flow rates based on the measurements made by the first and second measurement devices.

The present invention provides compositions and methods for use in enzyme replacement therapy. The inventors disclose a method of producing membrane bound enzymes in an active soluble form by eliminating the glycosylphosphatidylinositol (GPI) membrane anchor. In particular the inventors disclose a soluble active form of the membrane bound enzyme TNSALP which they produced by deleting the GPI anchor single peptide sequence. They have further shown that this composition is useful for treatment of hypophosphatasia. The inventors also disclose oligo acid amino acid variants thereof which specifically target bone tissue.

The present invention is directed to a device for a portable convection enhanced delivery system that allows administering liquids to specific locations within the body, especially tissues and tumors also allowing outsubject treatment. The application system comprises a portable extracorporal pump with a fluid reservoir that is connected via an infusion system to an infusion catheter placeable to any tissue or tumor the fluid should be administered to by high flow microperfusion. The system enables administration of fluids of any kind by convection enhanced delivery also in out-patient treatment. The system can be used for delivering various drugs, proteins, protein toxins, antibodies-for treatment or imaging, proteins in enzyme replacement therapy, growth factors and viruses or oligonucleotides in gene therapy etc. The application methods as well as the surgical method to implant this device are enclosed to this invention.

The invention relates to dose escalation enzyme replacement therapy using acid sphingomyelinase (ASM) for the treatment of human subjects having acid sphingomyelinase deficiency (ASMD), and, in particular, patients with non-neurological manifestations of Niemann-Pick Disease (NPD), and in certain embodiments, NPD type B.

A hormone replacement therapy, comprising a plurality of daily doses of a pharmaceutical preparation, the doses being administered continuously and consecutively in alternating phases of three daily doses, a relatively dominant estrogenic activity phase comprising three daily doses of a substance exhibiting estrogenic activity equivalent to about 1 mg per day of 17beta-estradiol per day, and a relatively dominant progestagenic activity phase of a combination of a substance exhibiting estrogenic activity equivalent to about 1 mg per day of 17beta-estradiol and a substance exhibiting progestogenic activity equivalent to about 90 mug per day of norgestimate.

The present invention provides improved formulations for lysosomal enzymes useful for enzyme replacement therapy. Among other things, the present invention provides formulations that preserve or enhance the stability and / or efficacy of a lysosomal enzyme such as acid alpha-glucosidase.

The present invention provides, as an enzyme which can be used for enzyme replacement therapy for Fabry disease, a protein having α-galactosidase activity, which shows no allergic adverse side effect, shows a high stability in blood, and can be easily incorporated into a cell of an affected organ. The protein of the present invention is a protein which has acquired α-galactosidase activity by changing the structure of the active site of wild-type human α-N-acetylgalactosaminidase.

The invention provides reagents and methods for enzyme replacement therapy using chemically modified species of human cystathionine β-synthase (CBS) to treat homocystinuria and other related diseases and disorders.
