Summary, etc. &lt;span style="font-size: 10pt;"&gt;The central nervous system has been proposed as a sanctuary site where HIV can escape antiretroviral control and develop drug resistance. HIV-1&amp;nbsp;&lt;span class="highlight" style="font-family: arial, helvetica, clean, sans-serif;"&gt;RNA&lt;/span&gt;&amp;nbsp;can be at higher levels in CSF than plasma, termed CSF/plasma discordance. We aimed to examine whether discordance in CSF is associated with low level viraemia (LLV) in blood. In this MRC-funded multicentre study, we prospectively recruited patients with LLV, defined as one or more episode of unexplained plasma HIV-1&amp;nbsp;&lt;span class="highlight" style="font-family: arial, helvetica, clean, sans-serif;"&gt;RNA&lt;/span&gt;&amp;nbsp;within 12&amp;nbsp;months, and undertook CSF examination. Separately, we prospectively collected CSF from patients undergoing lumbar puncture for a clinical indication. Patients with durable suppression of viraemia and no evidence of CNS infection were identified as controls from this group. Factors associated with CSF/plasma HIV-1 discordance overall were examined. One hundred fifty-three patients were recruited across 13 sites; 40 with LLV and 113 undergoing clinical lumbar puncture. Seven of the 40 (18&amp;nbsp;%) patients with LLV had CSF/plasma discordance, which was significantly more than 0/43 (0&amp;nbsp;%) with durable suppression in blood from the clinical group (p = 0.005). Resistance associated mutations were shown in six CSF samples from discordant patients with LLV (one had insufficient sample for testing), which affected antiretroviral therapy at sampling in five. Overall discordance was present in 20/153 (13&amp;nbsp;%) and was associated with nadir CD4 but not antiretroviral concentrations in plasma or CSF. CSF/plasma discordance is observed in patients with LLV and is associated with antiretroviral resistance associated mutations in CSF. The implications for clinical practice require further investigation.&lt;/span&gt;
