Summary of "Metabolic Changes in Lymphangioleiomyomatosis Patients Treated with Sirolimus and Hydroxychloroquine."

Lymphangioleiomyomatosis (LAM), a destructive lung disease that primarily affects women, is caused by loss-of-function mutations in TSC1 or TSC2, leading to hyperactivation of mechanistic/mammalian Target of Rapamycin 1 (mTORC1). Rapamycin (sirolimus) treatment suppresses mTORC1, but also induces autophagy, which promotes the survival of TSC2-deficient cells. Based on the hypothesis that simultaneous inhibition of mTORC1 and autophagy would limit the availability of critical nutrients and inhibit LAM cells, we conducted a Phase I clinical trial of sirolimus and hydroxychloroquine for LAM. Here, we report the analyses of plasma metabolomic profiles from the clinical trial.

Medical and Biotech [MESH] Definitions

A chemotherapeutic agent that acts against erythrocytic forms of malarial parasites. Hydroxychloroquine appears to concentrate in food vacuoles of affected protozoa. It inhibits plasmodial heme polymerase. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p970)

A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.

A derivative of sirolimus and an inhibitor of TOR SERINE-THREONINE KINASES. It is used to prevent GRAFT REJECTION in heart and kidney transplant patients by blocking cell proliferation signals. It is also an ANTINEOPLASTIC AGENT.

A hematopoietic growth factor which promotes proliferation and maturation of neutrophil granulocytes. Clinically it is effective in decreasing the incidence of febrile neutropenia in patients with non-myeloid malignancies receiving myelosuppressive therapy or in reducing the duration of neutropenia and neutropenia-related clinical sequelae in patients with non-myeloid malignancies undergoing myeloblastive chemotherapy followed by BMT. It has also been used in AIDS patients with CMV retinitis being treated with GANCICLOVIR. (Gelman CR, Rumack BH & Hess AJ (eds): DRUGDEX(R) System. MICROMEDEX, Inc., Englewood, Colorado (Edition expires 11/30/95))

Number of patients who need to be treated in order to prevent one additional bad outcome. It is the inverse of Absolute Risk Reduction.
