ACUTE RESPIRATORY SYNDROMES
Substance P or its analogs are useful for treating and protecting against acute respiratory syndromes including ARDS and SARS. The active agents can be administered via inhalation therapy, intravenously, intramuscularly, sublingually, or by other methods. Disease indicia are reduced by substance P treatment.
1 . A method of treating a SARS or ARDS patient, comprising:
administering to the patient an effective amount of an agent selected from the group consisting of: substance P, [Met-OH 11 ]-substance P, [Met-OMe 11 ]-substance P, [Nle 11 ]-substance P, [Pro 9 ]-substance P, [Sar 9 ]-substance P, [Tyr 8 ]-substance P, Sar 9 , Met (0 2 ) 11-Substance P, and [p-Cl-Phe 7,8 ]-substance P, whereby a disease feature selected from the group consisting of: Clara cell necrosis, pulmonary alveolar macrophage number, neutrophil number, alveolar-capillary barrier membrane damage, and 6-keto-PGF 1α and PGE 2 concentration is decreased.
2 . The method of claim 1 wherein the patient is a SARS patient.
3 . The method of claim 1 wherein the patient is an ARDS patient.
4 . The method of claim 1 wherein Sar 9 , Met (0 2 ) 11-Substance P is administered.
5 . The method of claim 1 wherein Substance P is administered.
6 . The method of claim 1 wherein the step of administering is performed by inhalation of an aerosol.
7 . The method of claim 1 wherein the step of administering is performed by intravenous delivery.
8 . The method of claim 1 wherein the step of administering is performed by intramuscular delivery.
9 . The method of claim 1 wherein the step of administering is performed by sublingual delivery.
10 . A method of protecting an individual prior to or after exposure to a patient with SARS or ARDS from developing SARS or ARDS, comprising:
administering to the individual an effective amount of an agent selected from the group consisting of substance P, [Met-OH 11 ]-substance P, [Met-OMe 11 ]-substance P, [Nle 11 ]-substance P, [Pro 9 ]-substance P, [Sar 9 ]-substance P, [Tyr 8 ]-substance P, Sar 9 ,Met (0 2 ) 11-Substance P, and [p-Cl-Phe 7,8 ]-substance P, whereby risk of developing SARS or ARDS is reduced.
11 . The method of claim 10 wherein the agent is substance P.
12 . The method of claim 10 wherein the agent is Sar 9 , Met (0 2 ) 11-Substance P.
13 . The method of claim 10 wherein the step of administering is performed by inhalation of an aerosol.
14 . The method of claim 10 wherein the step of administering is performed by intravenous delivery.
15 . The method of claim 10 wherein the step of administering is performed by intramuscular delivery.
16 . The method of claim 10 wherein the step of administering is performed by sublingual delivery.
