Abstract

A system for evaluating a subject, including: a processor in communication with a carbon monoxide (CO) detector, and a memory in communication with the processor having stored thereon a set of instructions which, when executed by the processor, cause the processor to: receive, from the CO detector, a measure of CO in a subject suspected of having at least one of autism spectrum disorder (ASD), autoimmunity, or inflammation; obtain a level of at least one biomarker associated with the subject based on receiving the measure of CO in the subject; and generate a report based on obtaining the level of the at least one biomarker.

Claims (51)

1 . A system for evaluating a subject, comprising:

a housing,

a processor in communication with a carbon monoxide (CO) detector, and

a memory in communication with the processor having stored thereon a set of instructions which, when executed by the processor, cause the processor to:

receive, from the CO detector, a measure of CO in a subject suspected of having at least one of autism spectrum disorder (ASD), autoimmunity, or inflammation;

determine a measure of ASD severity associated with the subject based on receiving the measure of CO in the subject by comparing the measure of CO to a calibration curve correlating the measure of ASD severity to the measure of CO; and

report the correlation between the measure of ASD severity to the measure of CO,

wherein the CO detector, the processor, and the memory are disposed within the housing.

2 . The system of claim 1 , wherein the processor, when receiving a measure of CO in a subject, is further caused by the instructions to:

receive a level of blood carbon monoxide (SpCO) in the subject.

3 . The system of claim 1 , wherein the system further comprises a user interface,

wherein the user interface is disposed within the housing, and

wherein the housing is configured to be coupled to the subject.

4 . The system of claim 1 , wherein the measure of CO comprises an average of measurements collected at a first time point and a second time point.

5 . The system of claim 1 , wherein the processor, when generating the report, is further caused by the instructions to:

generate the report indicating a level of ganglioside-monosialic acid (GM1) in the subject.

6 . The system of claim 1 , wherein the processor, when generating the report, is further caused by the instructions to:

generate the report indicating a treatment for the subject suspected of having at least one of ASD, autoimmunity, or inflammation.

7 . The system of claim 6 , wherein the processor, when indicating the treatment for the subject suspected of having at least one of ASD, autoimmunity, or inflammation, is further caused by the instructions to:

indicate the treatment comprising administration of a probiotic to the subject suspected of having at least one of ASD, autoimmunity, or inflammation.

8 . The system of claim 7 , wherein the processor, when indicating the treatment comprising administration of a probiotic to the subject suspected of having at least one of ASD, autoimmunity, or inflammation, is further caused by the instructions to:

indicate the treatment comprising administration of Lactobacillus plantarum probiotic to the subject suspected of having at least one of ASD, autoimmunity, or inflammation.

9 . The system of claim 6 , wherein the treatment is administered to the subject suspected of having at least one of ASD, autoimmunity, or inflammation for at least 16 weeks.

10 . The system of claim 1 , wherein the processor, when generating the report, is further caused by the instructions to:

generate the report indicating a subgrouping of the subject suspected of having ASD.

11 . The system of claim 1 , wherein the processor is further caused by the instructions to:

obtain a level of at least one biomarker based on a correlation between the measure of CO and level of the at least one biomarker.

12 . A method for evaluating a subject, comprising:

providing a housing;

receiving, from a processor in communication with a carbon monoxide (CO) detector, a measure of CO in a subject suspected of having at least one of autism spectrum disorder (ASD), autoimmunity, or inflammation,

wherein the processor and the CO detector are disposed within the housing;

determining, by the processor, a measure of ASD severity associated with the subject based on receiving the measure of CO in the subject by comparing the measure of CO to a calibration curve correlating the measure of ASD severity to the measure of CO; and

reporting the correlation between the measure of ASD severity to the measure of CO.

13 . The method of claim 12 , wherein receiving the measure of CO in the subject further comprises:

receiving a level of blood carbon monoxide (SpCO) in the subject.

14 . The method of claim 12 , wherein a user interface is disposed within the housing, and

wherein the housing is configured to be coupled to the subject.

15 . The method of claim 12 , wherein the measure of CO comprises an average of measurements collected at a first time point and a second time point.

16 . The method of claim 12 , wherein generating the report further comprises:

generating the report indicating a level of ganglioside-monosialic acid (GM1) in the subject.

17 . The method of claim 12 , wherein generating the report further comprises:

generating the report indicating a treatment for the subject suspected of having at least one of ASD, autoimmunity, or inflammation.

18 . The method of claim 17 , wherein indicating the treatment for the subject suspected of having at least one of ASD, autoimmunity, or inflammation further comprises:

indicating the treatment comprising administration of a probiotic to the subject suspected of having at least one of ASD, autoimmunity, or inflammation.

19 . The method of claim 18 , wherein indicating the treatment comprising administration of the probiotic to the subject suspected of having at least one of ASD, autoimmunity, or inflammation further comprises:

indicating the treatment comprising administration of Lactobacillus plantarum probiotic to the subject suspected of having at least one of ASD, autoimmunity, or inflammation.

20 . The method of claim 17 , wherein the treatment is administered to the subject suspected of having at least one of ASD, autoimmunity, or inflammation for at least 16 weeks.

21 . The method of claim 12 , wherein generating the report further comprises:

generating the report indicating a subgrouping of the subject suspected of having ASD.

22 . The method of claim 12 , wherein the method further comprises:

obtaining a level of at least one biomarker based on a correlation between the measure of CO and the level of the at least one biomarker.
