Pilot Study of Rapamycin as Treatment for Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Polycystic Kidney Diseases

This study is a prospective, randomized, open-label, pilot clinical trial designed to compare the effects of an agent that has antiproliferative (1,2), antiangiogenesis (3),and tumor-progression blocking capabilities (4), namely, rapamycin (Rapamune®), in the treatment of autosomal-dominant polycystic kidney disease (ADPKD). Up to this time, only generic renal disease treatments for ADPKD have been in use, such as the treatment of hypertension, urinary tract infections, renal stones, renal call carcinomas, and replacement therapy with dialysis and/or renal transplantation. The fundamental aberrations in ADPKD are proliferation of cyst-forming tubuloepithelial cells, secretion of cytokine-rich fluid into those cysts, and progressive cyst expansion and release of inflammatory mediators that injure surrounding normal renal tissue. Consequently, therapy directed specifically at blocking the proliferation of tubuloepithelial cells and their tendency to malignant transformation, as well as impeding their blood supply, should have obvious merit. General Procedures: In Group I participants will have an iothalamate glomerular filtration rate (GFR) equal to or greater than 60 ml/min/1.73 m2, and in Group II participants will have a GFR less than 25-59 ml/min/1.73 m2. Both males and females with ADPKD who volunteer and qualify, will be randomly and prospectively assigned to treatment with rapamycin at either a high or low trough blood level or to standard care (each 1/3 of enrolled patients) for one year. The two treatment groups will receive rapamycin doses aimed at maintaining the 20- to 24-hour trough blood levels at either 2 to 5 ng/mL (low-dose), or greater than 5 to 8 ng/mL (high-dose). These trough levels are in the lower range of levels used when treating renal transplant recipients in whom trough levels are typically maintained between 5 and 15 ng/mL.

Autosomal Dominant Polycystic Kidney Disease

ADPKD patients who were enrolled in Study 156-05-002 will receive repeated oral administration of OPC-41061 at doses of 15 mg twice daily (morning and evening). Administration will be continued until the time of manufacturing and distribution approval of OPC-41061 for ADPKD in Japan.

Using Preimplantation Genetic Diagnosis in Autosomal Dominant Polycystic Kidney Disease Patients:...

Polycystic KidneyType 1 Autosomal Dominant Disease

Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic hereditary kidney disease in humans. ADPKD may affect all the generations of the ADPKD family and the probability of ADPKD is 50% in the second generation for each gender. It has been confirmed that PKD1 and PKD2 are two pathogenic genes of ADPKD. Nowadays, the investigators have established an effective gene detection technology platform for PKD1/2 gene with long fragment PCR and next generation sequencing. First, the investigators performed genetic testing in patients with clinically diagnosed ADPKD and strong fertility desire, but afraid of hereditary risk. Using Preimplantation genetic diagnosis, including multiple annealing and looping-based amplification cycles amplification technique, the investigators successfully screened out healthy embryos by In Vitro Fertilization. Then the investigators transplanted embryos returned to the parent. When the baby is born, using umbilical cord blood gene detection, the investigators confirmed that the neonates do not inherit genetic defects form parents. The investigators have succeeded in one couple. The investigators design a multicenter clinical trial to confirm those procedures efficacy and safety.

Adrenal Functions in Autosomal Dominant Polycystic Kidney Disease

Autosomal Dominant Polycystic Kidney Disease

We aimed to evaluate the hypothalamus-pituitary-adrenal axis in autosomal dominant polycystic kidney disease (ADPKD) patients. Twenty two ADPKD patients and 27 healthy subjects were enrolled.

A New Diet for Patients With Autosomal Dominant Polycystic Disease (ADPKD)

Autosomal Dominant Polycystic Kidney Disease

Recent evidence has shown that kidney volume predicts the likelihood of developing renal insufficiency over a finite length of time in ADPKD, suggesting a linkage between the growth of cysts and the harm they do to kidney function. Recent studies indicate that the rate of kidney volume increase is hastened by excess dietary protein, salt, and potential net acid precursors, and slowed by increased water intake sufficient to lower plasma vasopressin levels. Diets are commonly prescribed to treat ADPKD and other renal patients with disease near the end-stage, but there is currently no specific diet prescription that takes potentially harmful dietary elements into account for ADPKD patients in the earliest stages of the disease. This study will examine a novel diet for ADPKD created by the researcher termed the ADPKD diet.
