Abstract
IntroductionHistorically, single tissue vasculitis has been managed with steroid monotherapy. Recent data from large longitudinal databases on systemic vasculitis suggest Non-Systemic Vasculitic Neuropathy (NSVN) has higher rates of relapse, recommending that more aggressive immunotherapy is employed.AimTo investigate the relapse rate in NSVN in response to steroid monotherapy.MethodsA retrospective case note review of clinically and/or pathologically defined cases of (Systemic Vasculitic Neuropathy) SVN and NSVN in two London specialist peripheral nerve centres, between 2005- 2012 and 2015 - 2019.Results32 cases of SVN and 34 cases of NSVN were identified. In each group 14 individuals were treated first-line with steroid monotherapy, and 8 with cyclophosphamide. 8 SVN and 9 NSVN cases received steroids plus azathioprine. 15/32 SVN and 13/34 NSVN relapsed after first-line therapy (10/14 and 9/14 on steroid monotherapy, 3/8 and 3/9 on steroids and azathioprine, 2/8 and 1/8 on cyclophosphamide). 10 individuals stabilised with the addition of azathioprine, 13 with cyclophosphamide and 4 with Rituximab.ConclusionThis representative case series suggests that steroid monotherapy is inadequate in the treatment of NSVN and supports an approach akin to that recommended in SVN, even if nerve is the only tissue clinically involved.e.bunting@nhs.net

Abstract
BACKGROUND Patients with major depressive disorder (MDD) having active suicidal ideation with intent require immediate treatment. METHODS This double-blind study (ASPIRE II) randomized adults (aged 18-64 years) with MDD having active suicidal ideation with intent to esketamine 84 mg or placebo nasal spray twice weekly for 4 weeks, given with comprehensive standard of care (hospitalization ≥5 days and newly initiated or optimized oral antidepressant[s]). Change from baseline to 24 hours post-first dose in Montgomery-Asberg Depression Rating Scale total score (primary efficacy endpoint) was analyzed using ANCOVA. Clinical Global Impression-Severity of Suicidality-revised (key secondary endpoint) was analyzed using ANCOVA on ranks of change. RESULTS Of 230 patients who were randomized (115 per arm), 227 received study drug and were included in efficacy/safety analyses; 184 (80.0%) completed double-blind treatment. Greater improvement in Montgomery-Asberg Depression Rating Scale total score was observed with esketamine (mean [SD]: -15.7 [11.56]) vs placebo (-12.4 [10.43]), each with standard of care, at 24 hours (least-squares mean difference [SE]: -3.9 [1.39], 95% CI: -6.60, -1.11; 2-sided P = .006). This was also noted at the earlier (4-hour) timepoint (least-squares mean difference -4.2, 95% CI: -6.38, -1.94). Patients in both treatment groups experienced rapid reduction in Clinical Global Impression-Severity of Suicidality-revised score; the between-group difference was not statistically significant. The most common adverse events among esketamine-treated patients were dizziness, dissociation, nausea, dysgeusia, somnolence, headache, and paresthesia. CONCLUSION This study confirmed rapid and robust reduction of depressive symptoms with esketamine nasal spray in severely ill patients with MDD who have active suicidal ideation with intent.

Abstract
The use of digital health products has gained considerable interest as a new way to improve therapeutic research and development. Although these products are being adopted by various industries and stakeholders, their incorporation in clinical trials has been slow due to a disconnect between the promises of digital products and potential risks in using these new technologies in the absence of regulatory support. The Foundation for the National Institutes of Health (FNIH) Biomarkers Consortium hosted a public workshop to address challenges and opportunities in this field. Important characteristics of tool development were addressed in a series of presentations, case studies, and open panel sessions. The workshop participants endorsed the usefulness of an evidentiary criteria framework, highlighted the importance of early patient engagement, and emphasized the potential impact of digital monitoring tools and precompetitive collaborations. Concerns were expressed about the lack of real‐life validation examples and the limitations of legacy standards used as a benchmark for novel tool development and validation. Participants recognized the need for novel analytical and statistical approaches to accommodate analyses of these novel data types. Future directions are to harmonize definitions to build common methodologies and foster multidisciplinary collaborations; to develop approaches toward integrating digital monitoring data with the totality of the data in clinical trials, and to continue an open dialog in the community. There was a consensus that all these efforts combined may create a paradigm shift of how clinical trials are planned, conducted, and results brought to regulatory reviews.

Abstract
OBJECTIVE To compare esketamine to placebo, each in addition to standard-of-care treatment, for rapidly reducing major depressive disorder symptoms, including suicidal ideation. METHODS This phase 3, double-blind, multicenter study (ASPIRE I), conducted between June 2017 and December 2018, enrolled 226 adults having major depressive disorder based on Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) criteria, active suicidal ideation with intent, and need for psychiatric hospitalization. Patients were randomized 1:1 to esketamine 84 mg or placebo nasal spray twice-weekly for 4 weeks, each with comprehensive standard-of-care treatment (initial psychiatric hospitalization and newly initiated or optimized oral antidepressant[s] therapy). Change from baseline to 24 hours post-first dose in Montgomery-Asberg Depression Rating Scale (MADRS) total score (primary endpoint) was analyzed using analysis of covariance (ANCOVA), and change in Clinical Global Impression of Severity of Suicidality Revised version (CGI-SS-r; key secondary endpoint) score was analyzed using ANCOVA on ranks with treatment difference estimated using the Hodges-Lehmann estimate. RESULTS Greater improvement in MADRS total score was observed with esketamine + standard-of-care versus placebo + standard-of-care at 24 hours (least-squares mean difference [SE]: -3.8 [1.39]; 95% CI, -6.56 to -1.09; 2-sided P = .006), as well as at earlier (4 hours) and later time points during 4-week double-blind treatment. The difference between groups in the severity of suicidality was not statistically significant (median of treatment difference [95% CI]: 0.0 [-1.00 to 0.00]; 2-sided P = .107). The most common adverse events among esketamine-treated patients were dizziness, dissociation, headache, nausea, and somnolence. CONCLUSIONS These findings demonstrate rapid and robust efficacy of esketamine nasal spray in reducing depressive symptoms in severely ill patients with major depressive disorder who have active suicidal ideation with intent.

Abstract
OBJECTIVE To evaluate long-term safety and efficacy of esketamine nasal spray plus a new oral antidepressant (OAD) in patients with treatment-resistant depression (TRD). METHODS This phase 3, open-label, multicenter, long-term (up to 1 year) study was conducted between October 2015 and October 2017. Patients (≥ 18 years) with TRD (DSM-5 diagnosis of major depressive disorder and nonresponse to ≥ 2 OAD treatments) were enrolled directly or transferred from a short-term study (patients aged ≥ 65 years). Esketamine nasal spray (28-mg, 56-mg, or 84-mg) plus new OAD was administered twice a week in a 4-week induction (IND) phase and weekly or every-other-week for patients who were responders and entered a 48-week optimization/maintenance (OP/MAINT) phase. RESULTS Of 802 enrolled patients, 86.2% were direct-entry and 13.8% were transferred-entry; 580 (74.5%) of 779 patients who entered the IND phase completed the phase, and 150 (24.9%) of 603 who entered the OP/MAINT phase completed the phase. Common treatment-emergent adverse events (TEAEs) were dizziness (32.9%), dissociation (27.6%), nausea (25.1%), and headache (24.9%). Seventy-six patients (9.5%) discontinued esketamine due to TEAEs. Fifty-five patients (6.9%) experienced serious TEAEs. Most TEAEs occurred on dosing days, were mild or moderate in severity, and resolved on the same day. Two deaths were reported; neither was considered related to esketamine. Cognitive performance generally either improved or remained stable postbaseline. There was no case of interstitial cystitis or respiratory depression. Treatment-emergent dissociative symptoms were transient and generally resolved within 1.5 hours postdose. Montgomery-Åsberg Depression Rating Scale total score decreased during the IND phase, and this reduction persisted during the OP/MAINT phase (mean [SD] change from baseline of respective phase to endpoint: IND, -16.4 [8.76]; OP/MAINT, 0.3 [8.12]). CONCLUSIONS Long-term esketamine nasal spray plus new OAD therapy had a manageable safety profile, and improvements in depression appeared to be sustained in patients with TRD.

Abstract
BACKGROUND Elderly patients with major depression have a poorer prognosis, are less responsive to treatment, and show greater functional decline compared with younger patients, highlighting the need for effective treatment. METHODS This phase 3 double-blind study randomized patients with treatment-resistant depression (TRD) ≥65 years (1:1) to flexibly dosed esketamine nasal spray and new oral antidepressant (esketamine/antidepressant) or new oral antidepressant and placebo nasal spray (antidepressant/placebo). The primary endpoint was change in the Montgomery-Åsberg Depression Rating Scale (MADRS) from baseline to day 28. Analyses included a preplanned analysis by age (65-74 versus ≥75 years) and post-hoc analyses including age at depression onset. RESULTS For the primary endpoint, the median-unbiased estimate of the treatment difference (95% CI) was -3.6 (-7.20, 0.07); weighted combination test using MMRM analyses z = 1.89, two-sided p = 0.059. Adjusted mean (95% CI) difference for change in MADRS score between treatment groups was -4.9 (-8.96, -0.89; t = -2.4, df = 127; two-sided nominal p = 0.017) for patients 65 to 74 years versus -0.4 (-10.38, 9.50; t = -0.09, two-sided nominal p = 0.930) for those ≥75 years, and -6.1 (-10.33, -1.81; t = -2.8, df = 127; two-sided nominal p = 0.006) for patients with depression onset <55 years and 3.1 (-4.51, 10.80; t = 0.8, two-sided nominal p = 0.407) for those ≥55 years. Patients who rolled over into the long-term open-label study showed continued improvement with esketamine following 4 additional treatment weeks. CONCLUSIONS Esketamine/antidepressant did not achieve statistical significance for the primary endpoint. Greater differences between treatment arms were seen for younger patients (65-74 years) and patients with earlier onset of depression (<55 years).

Abstract
IMPORTANCE Controlled studies have shown short-term efficacy of esketamine for treatment-resistant depression (TRD), but long-term effects remain to be established. OBJECTIVE To assess the efficacy of esketamine nasal spray plus an oral antidepressant compared with an oral antidepressant plus placebo nasal spray in delaying relapse of depressive symptoms in patients with TRD in stable remission after an induction and optimization course of esketamine nasal spray plus an oral antidepressant. DESIGN, SETTING, AND PARTICIPANTS In this phase 3, multicenter, double-blind, randomized withdrawal study conducted from October 6, 2015, to February 15, 2018, at outpatient referral centers, 705 adults with prospectively confirmed TRD were enrolled; 455 entered the optimization phase and were treated with esketamine nasal spray (56 or 84 mg) plus an oral antidepressant. After 16 weeks of esketamine treatment, 297 who achieved stable remission or stable response entered the randomized withdrawal phase. INTERVENTIONS Patients who achieved stable remission and those who achieved stable response (without remission) were randomized 1:1 to continue esketamine nasal spray or discontinue esketamine treatment and switch to placebo nasal spray, with oral antidepressant treatment continued in each group. MAIN OUTCOMES AND MEASURES Time to relapse was examined in patients who achieved stable remission, as assessed using a weighted combination log-rank test. RESULTS Among the 297 adults (mean age [SD], 46.3 [11.13] years; 197 [66.3%] female) who entered the randomized maintenance phase, 176 achieved stable remission; 24 (26.7%) in the esketamine and antidepressant group and 39 (45.3%) in the antidepressant and placebo group experienced relapse (log-rank P = .003, number needed to treat [NNT], 6). Among the 121 who achieved stable response, 16 (25.8%) in the esketamine and antidepressant group and 34 (57.6%) in the antidepressant and placebo group experienced relapse (log-rank P < .001, NNT, 4). Esketamine and antidepressant treatment decreased the risk of relapse by 51% (hazard ratio [HR], 0.49; 95% CI, 0.29-0.84) among patients who achieved stable remission and 70% (HR, 0.30; 95% CI, 0.16-0.55) among those who achieved stable response compared with antidepressant and placebo treatment. The most common adverse events reported for esketamine-treated patients after randomization were transient dysgeusia, vertigo, dissociation, somnolence, and dizziness (incidence, 20.4%-27.0%), each reported in fewer patients (<7%) treated with an antidepressant and placebo. CONCLUSIONS AND RELEVANCE For patients with TRD who experienced remission or response after esketamine treatment, continuation of esketamine nasal spray in addition to oral antidepressant treatment resulted in clinically meaningful superiority in delaying relapse compared with antidepressant plus placebo.

Abstract
BACKGROUND About one-third of patients with depression fail to achieve remission despite treatment with multiple antidepressants and are considered to have treatment-resistant depression. METHODS This Phase 3, double-blind, multicenter study enrolled adults with moderate-to-severe depression and nonresponse to ≥2 antidepressants in the current depression episode. Eligible patients (N = 346) were randomized (1:1:1) to twice-weekly nasal spray treatment (esketamine [56 or 84 mg] or placebo) plus a newly initiated, open-label, oral antidepressant taken daily for 4 weeks. The primary efficacy endpoint was change from baseline to day 28 in the Montgomery-Asberg Depression Rating Scale total score, performed by blinded, remote raters. Based on the predefined statistical testing sequence, esketamine 84 mg/antidepressant had to be significant for esketamine 56 mg/antidepressant to be formally tested. RESULTS Statistical significance was not achieved with esketamine 84 mg/antidepressant compared with antidepressant/placebo (least squares [LS] means difference [95% CI]: -3.2 [-6.88, 0.45]; 2-sided P value = .088). Although esketamine 56 mg/antidepressant could not be formally tested, the LS means difference was -4.1 [-7.67, -0.49] (nominal 2-sided P value = .027). The most common (>20%) adverse events reported for esketamine/antidepressant were nausea, dissociation, dizziness, vertigo, and headache. CONCLUSIONS Statistical significance was not achieved for the primary endpoint; nevertheless, the treatment effect (Montgomery-Asberg Depression Rating Scale) for both esketamine/antidepressant groups exceeded what has been considered clinically meaningful for approved antidepressants vs placebo. Safety was similar between esketamine/antidepressant groups and no new dose-related safety concerns were identified. This study provides supportive evidence for the safety and efficacy of esketamine nasal spray as a new, rapid-acting antidepressant for patients with treatment-resistant depression.

Abstract
Digital technologies-including smartphones, wearables, and social media data-show great potential for helping to alleviate suffering from brain disorders such as Parkinson's disease, Alzheimer's disease, depression, and schizophrenia. However, as researchers, technology developers, disease-focused groups, and others forge forward to take advantage of the tremendous opportunities in this domain, it is important to avoid hype and overpromising, and to ensure that this work is done rigorously and collaboratively. In June 2018, the National Academies of Sciences, Engineering, and Medicine's Forum on Neuroscience and Nervous System Disorders hosted a workshop that brought together a wide range of experts and stakeholders. The workshop provided an opportunity to take stock of the rapidly-evolving landscape and discuss how to work together to address both scientific and practical challenges, so that the potential of digital technologies can be translated into meaningful contributions toward the health of individuals and society. Workshop presentations and discussions focused on four key challenges: transforming data into insight, navigating regulatory pathways, designing user-centered tools, and building partnerships across a complex ecosystem. This article highlights the many issues, challenges, and opportunities discussed by individual participants at the workshop.

Abstract
OBJECTIVE About one-third of patients with depression fail to achieve remission despite treatment with multiple antidepressants. This study compared the efficacy and safety of switching patients with treatment-resistant depression from an ineffective antidepressant to flexibly dosed esketamine nasal spray plus a newly initiated antidepressant or to a newly initiated antidepressant (active comparator) plus placebo nasal spray. METHODS This was a phase 3, double-blind, active-controlled, multicenter study conducted at 39 outpatient referral centers. The study enrolled adults with moderate to severe nonpsychotic depression and a history of nonresponse to at least two antidepressants in the current episode, with one antidepressant assessed prospectively. Confirmed nonresponders were randomly assigned to treatment with esketamine nasal spray (56 or 84 mg twice weekly) and an antidepressant or antidepressant and placebo nasal spray. The primary efficacy endpoint, change from baseline to day 28 in Montgomery-Åsberg Depression Rating Scale (MADRS) score, was assessed by a mixed-effects model using repeated measures. RESULTS Of 435 patients screened, 227 underwent randomization and 197 completed the 28-day double-blind treatment phase. Change in MADRS score with esketamine plus antidepressant was significantly greater than with antidepressant plus placebo at day 28 (difference of least square means=-4.0, SE=1.69, 95% CI=-7.31, -0.64); likewise, clinically meaningful improvement was observed in the esketamine plus antidepressant arm at earlier time points. The five most common adverse events (dissociation, nausea, vertigo, dysgeusia, and dizziness) all were observed more frequently in the esketamine plus antidepressant arm than in the antidepressant plus placebo arm; 7% and 0.9% of patients in the respective treatment groups discontinued study drug because of an adverse event. Adverse events in the esketamine plus antidepressant arm generally appeared shortly after dosing and resolved by 1.5 hours after dosing. CONCLUSIONS Current treatment options for treatment-resistant depression have considerable limitations in terms of efficacy and patient acceptability. Esketamine is expected to address an unmet medical need in this population through its novel mechanism of action and rapid onset of antidepressant efficacy. The study supports the efficacy and safety of esketamine nasal spray as a rapidly acting antidepressant for patients with treatment-resistant depression.

Abstract
OBJECTIVE The authors compared the efficacy of standard-of-care treatment plus intranasal esketamine or placebo for rapid reduction of symptoms of major depression, including suicidality, among individuals at imminent suicide risk. METHOD In a double-blind, multicenter, proof-of-concept study, 68 participants were randomly assigned to receive esketamine (84 mg) or placebo twice weekly for 4 weeks, in addition to comprehensive standard-of-care treatment. The primary efficacy endpoint was change in score from baseline to 4 hours after initial dose on the Montgomery-Åsberg Depression Rating Scale (MADRS). Clinician global judgment of suicide risk (from the Suicide Ideation and Behavior Assessment Tool) was also assessed. Secondary endpoints included these measures at 24 hours and double-blind endpoint at day 25. RESULTS A significantly greater improvement in MADRS score was observed in the esketamine group compared with the placebo group at 4 hours (least-square mean difference=-5.3, SE=2.10; effect size=0.61) and at ∼24 hours (least-square mean difference=-7.2, SE=2.85; effect size=0.65), but not at day 25 (least-square mean difference=-4.5, SE=3.14; effect size=0.35). Significantly greater improvement was also observed in the esketamine group on the MADRS suicidal thoughts item score at 4 hours (effect size=0.67), but not at 24 hours (effect size=0.35) or at day 25 (effect size=0.29). Between-group reductions in clinician global judgment of suicide risk scores were not statistically different at any time point. The most common adverse events among participants in the esketamine group were nausea, dizziness, dissociation, unpleasant taste, and headache. CONCLUSIONS These preliminary findings indicate that intranasal esketamine compared with placebo, given in addition to comprehensive standard-of-care treatment, may result in significantly rapid improvement in depressive symptoms, including some measures of suicidal ideation, among depressed patients at imminent risk for suicide.

Abstract
Importance Approximately one-third of patients with major depressive disorder (MDD) do not respond to available antidepressants. Objective To assess the efficacy, safety, and dose-response of intranasal esketamine hydrochloride in patients with treatment-resistant depression (TRD). Design, Setting, and Participants This phase 2, double-blind, doubly randomized, delayed-start, placebo-controlled study was conducted in multiple outpatient referral centers from January 28, 2014, to September 25, 2015. The study consisted of 4 phases: (1) screening, (2) double-blind treatment (days 1-15), composed of two 1-week periods, (3) optional open-label treatment (days 15-74), and (4) posttreatment follow-up (8 weeks). One hundred twenty-six adults with a DSM-IV-TR diagnosis of MDD and history of inadequate response to 2 or more antidepressants (ie, TRD) were screened, 67 were randomized, and 60 completed both double-blind periods. Intent-to-treat analysis was used in evaluation of the findings. Interventions In period 1, participants were randomized (3:1:1:1) to placebo (n = 33), esketamine 28 mg (n = 11), 56 mg (n = 11), or 84 mg (n = 12) twice weekly. In period 2, 28 placebo-treated participants with moderate-to-severe symptoms were rerandomized (1:1:1:1) to 1 of the 4 treatment arms; those with mild symptoms continued receiving placebo. Participants continued their existing antidepressant treatment during the study. During the open-label phase, dosing frequency was reduced from twice weekly to weekly, and then to every 2 weeks. Main Outcomes and Measures The primary efficacy end point was change from baseline to day 8 (each period) in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Results Sixty-seven participants (38 women, mean [SD] age, 44.7 [10.0] years) were included in the efficacy and safety analyses. Change (least squares mean [SE] difference vs placebo) in MADRS total score (both periods combined) in all 3 esketamine groups was superior to placebo (esketamine 28 mg: -4.2 [2.09], P = .02; 56 mg: -6.3 [2.07], P = .001; 84 mg: -9.0 [2.13], P < .001), with a significant ascending dose-response relationship (P < .001). Improvement in depressive symptoms appeared to be sustained (-7.2 [1.84]) despite reduced dosing frequency in the open-label phase. Three of 56 (5%) esketamine-treated participants during the double-blind phase vs none receiving placebo and 1 of 57 participants (2%) during the open-label phase had adverse events that led to study discontinuation (1 event each of syncope, headache, dissociative syndrome, and ectopic pregnancy). Conclusions and Relevance In this first clinical study to date of intranasal esketamine for TRD, antidepressant effect was rapid in onset and dose related. Response appeared to persist for more than 2 months with a lower dosing frequency. Results support further investigation in larger trials. Trial Registration clinicaltrials.gov identifier: NCT01998958.

Abstract
Genome-wide association studies (GWAS) in psychiatry, once they reach sufficient sample size and power, have been enormously successful. The Psychiatric Genomics Consortium (PGC) aims for mega-analyses with sample sizes that will grow to >1 million individuals in the next 5 years. This should lead to hundreds of new findings for common genetic variants across nine psychiatric disorders studied by the PGC. The new targets discovered by GWAS have the potential to restart largely stalled psychiatric drug development pipelines, and the translation of GWAS findings into the clinic is a key aim of the recently funded phase 3 of the PGC. This is not without considerable technical challenges. These approaches complement the other main aim of GWAS studies, risk prediction approaches for improving detection, differential diagnosis, and clinical trial design. This paper outlines the motivations, technical and analytical issues, and the plans for translating PGC phase 3 findings into new therapeutics.

Abstract
OBJECTIVE Ketamine, an N-methyl-d-aspartate glutamate receptor antagonist, has demonstrated a rapid-onset antidepressant effect in patients with treatment-resistant depression. This study evaluated the efficacy of twice- and thrice-weekly intravenous administration of ketamine in sustaining initial antidepressant effects in patients with treatment-resistant depression. METHOD In a multicenter, double-blind study, adults (ages 18-64 years) with treatment-resistant depression were randomized to receive either intravenous ketamine (0.5 mg/kg of body weight) or intravenous placebo, administered over 40 minutes, either two or three times weekly, for up to 4 weeks. Patients who discontinued double-blind treatment after at least 2 weeks for lack of efficacy could enter an optional 2-week open-label phase to receive ketamine with the same frequency as in the double-blind phase. The primary outcome measure was change from baseline to day 15 in total score on the Montgomery-Åsberg Depression Rating Scale (MADRS). RESULTS In total, 67 (45 women) of 68 randomized patients received treatment. In the twice-weekly dosing groups, the mean change in MADRS score at day 15 was -18.4 (SD=12.0) for ketamine and -5.7 (SD=10.2) for placebo; in the thrice-weekly groups, it was -17.7 (SD=7.3) for ketamine and -3.1 (SD=5.7) for placebo. Similar observations were noted for ketamine during the open-label phase (twice-weekly, -12.2 [SD=12.8] on day 4; thrice-weekly, -14.0 [SD=12.5] on day 5). Both regimens were generally well tolerated. Headache, anxiety, dissociation, nausea, and dizziness were the most common (≥20%) treatment-emergent adverse events. Dissociative symptoms occurred transiently and attenuated with repeated dosing. CONCLUSIONS Twice-weekly and thrice-weekly administration of ketamine at 0.5 mg/kg similarly maintained antidepressant efficacy over 15 days.

Abstract
We report clinical, radiological and virological data from nine consecutive HIV-infected patients with herpes simplex virus (HSV) infection of the central nervous system (CNS). Three patients presented with confusion, two with fever and headache, two with anxiety and depression, one with slow mentation and memory loss and one with expressive dysphasia. Five patients had previous AIDS-defining diagnoses: four of these five patients had previous cutaneous HSV infection. HSV DNA was detected by the polymerase chain reaction (PCR) on cerebrospinal fluid (CSF) in seven patients. HSV infection was diagnosed by brain biopsy (after negative PCR on CSF) in one patient and at autopsy in one patient (after negative CSF PCR and brain biopsy). Seven patients received specific anti-viral therapy; two died of unrelated causes and the other five recovered. Two patients were not treated, in one the diagnosis was made at autopsy and the other recovered spontaneously. HIV-infected patients with CNS HSV infection have a varied presentation. Diagnosis by PCR on CSF identified the majority of cases. With specific treatment the outcome was good.
