Abstract: A method of preventing transmission of a retrovirus from a mother to her offspring, by administering to the mother a therapeutically effective amount of a composition comprising a Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-associated endonuclease, and the two or more different multiplex gRNAs, wherein each of the at least two gRNAs is complementary to a different target nucleic acid sequence in a long terminal repeat (LTR) of proviral DNA of the virus that is unique from the genome of the host cell, cleaving a double strand of the proviral DNA at a first target protospacer sequence with the CRISPR-associated endonuclease, cleaving a double strand of the proviral DNA at a second target protospacer sequence with the CRISPR-associated endonuclease, excising an entire HIV-1 proviral genome, eradicating the HIV-1 proviral DNA from the host cell, and preventing transmission of the proviral DNA to the offspring.

Abstract: Provided is a method of detecting mild neurocognitive disturbance (MNCD) or HIV associated dementia (HAD) in a patient comprising detecting the level of acetyl spermine and/or acetyl spermidine from a cerebrospinal fluid test sample of the patient; and comparing the level of acetyl spermine and/or acetyl spermidine in the test sample to the level of the acetyl spermine and/or acetyl spermidine in a cerebrospinal fluid control sample or to a control value for lack of neurocognitive impairment, MNCD or HAD; wherein an elevated level of acetyl spermine and/or acetyl spermidine in the test sample as compared to the level in the control sample or a control value for lack of neurocognitive impairment, or a level of acetyl spermine and/or acetyl spermidine that is similar to that of a control value for MNCD or HAD, indicates that the patient suffers from MNCD or HAD. Also provided are methods for measuring the progression of an HIV-1-associated neurocognitive disorder, as well as methods for staging such a disorder.
