Abstract
OBJECTIVE This article discusses the clinical manifestations and management of infectious peripheral neuropathies. LATEST DEVELOPMENTS Several infectious etiologies of peripheral neuropathy are well-recognized and their treatments are firmly established. The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with several central and peripheral nervous system manifestations, including peripheral neuropathies. Additionally, some COVID-19 vaccines have been associated with Guillain-Barré syndrome. These disorders are an active area of surveillance and research. Recent evidence-based guidelines have provided updated recommendations for the diagnosis and treatment of Lyme disease. ESSENTIAL POINTS Infectious agents of many types (primarily bacteria and viruses) can affect the peripheral nerves, resulting in various clinical syndromes such as mononeuropathy or mononeuropathy multiplex, distal symmetric polyneuropathy, radiculopathy, inflammatory demyelinating polyradiculoneuropathy, and motor neuronopathy. Knowledge of these infections and the spectrum of peripheral nervous system disorders associated with them is essential because many have curative treatments. Furthermore, understanding the neuropathic presentations of these disorders may assist in diagnosing the underlying infection.

Abstract
Neurologic complications are common in immunocompromised patients, including those with advanced human immunodeficiency virus, transplant recipients, and patients on immunomodulatory medications. In addition to the standard differential diagnosis, specific pathogens and other conditions unique to the immunocompromised state should be considered in the evaluation of neurologic complaints in this patient population. A thorough understanding of these considerations is critical to the inpatient neurologist in contemporary practice, as increasing numbers of patients are exposed to immunomodulatory therapies. In this review, we provide a chief complaint-based approach to the clinical presentations and diagnosis of both infectious and noninfectious complications particular to immunocompromised patients.

Abstract
With increasing survival of patients infected with human immunodeficiency virus type 1 (HIV-1), the manifestation of heterogeneous neurological complications is also increasing alarmingly in these patients. Currently, more than 30% of about 40 million HIV-1 infected people worldwide develop central nervous system (CNS)-associated dysfunction, including dementia, sensory, and motor neuropathy. Furthermore, the highly effective antiretroviral therapy has been shown to increase the prevalence of mild cognitive functions while reducing other HIV-1-associated neurological complications. On the contrary, the presence of neurological disorder frequently affects the outcome of conventional HIV-1 therapy. Although, both the children and adults suffer from the post-HIV treatment-associated cognitive impairment, adults, especially depending on the age of disease onset, are more prone to CNS dysfunction. Thus, addressing neurological complications in an HIV-1-infected patient is a delicate balance of several factors and requires characterization of the molecular signature of associated CNS disorders involving intricate cross-talk with HIV-1-derived neurotoxins and other cellular factors. In this review, we summarize some of the current data supporting both the direct and indirect mechanisms, including neuro-inflammation and genome instability in association with aging, leading to CNS dysfunction after HIV-1 infection, and discuss the potential strategies addressing the treatment or prevention of HIV-1-mediated neurotoxicity.

Differential diagnosis and treatment of acute cauda equina syndrome in the human immunodeficiency virus positive patient: a case report and review of the literature. J Med Case Rep 2016; 10:165.

Abstract
BACKGROUND Acute cauda equina syndrome is an uncommon but significant neurologic presentation due to a variety of underlying diseases. Anatomical compression of nerve roots, usually by a lumbar disk hernia is a common cause in the general population, while inflammatory, neoplastic, and ischemic causes have also been recognized. Among human immunodeficiency virus (HIV) infected patients with acquired immunodeficiency syndrome, infectious causes are encountered more frequently, the most prevalent of which are: cytomegalovirus, herpes simplex virus 1/2, varicella zoster virus, and Mycobacterium tuberculosis infections. Studies of cauda equina syndrome in well-controlled HIV infection are lacking. We describe such a case of cauda equina syndrome in a well-controlled HIV-infected patient, along with a brief review of the literature regarding the syndrome's diagnosis and treatment in individuals with HIV infection. CASE PRESENTATION A 36-year-old Greek male, HIV-positive patient presented with perineal and left hemiscrotal numbness, lumbar pain, left-sided sciatica, and urinary incontinence. Magnetic resonance imaging of the patient's lumbar spine revealed intrathecal migration of a fragment from an intervertebral lumbar disk exerting pressure on the cauda equina. A cerebrospinal fluid examination, brain computed tomography scan, spine magnetic resonance imaging, and serological test results were negative for central nervous system infections. Our patient underwent emergency neurosurgical spinal decompression, which resolved most symptoms, except for mild urinary incontinence. CONCLUSIONS Noninfectious etiologies may also cause cauda equina syndrome in HIV-infected individuals, especially in well-controlled disease under antiretroviral therapy. Prompt recognition and treatment of the underlying cause is important to minimize residual symptoms. Targeted antimicrobial chemotherapy is used to treat infectious causes, while prompt surgical decompression is favored for anatomical causes of cauda equina syndrome in the HIV-infected patient.

Abstract
OBJECTIVE Neuroimaging abnormalities in central nervous system (CNS) brucellosis are not well documented. The purpose of this study was to evaluate the prevalence of imaging abnormalities in neurobrucellosis and to identify factors associated with leptomeningeal and basal enhancement, which frequently results in unfavorable outcomes. METHODS Istanbul-3 study evaluated 263 adult patients with CNS brucellosis from 26 referral centers and reviewed their 242 magnetic resonance imaging (MRI) and 226 computerized tomography (CT) scans of the brain. RESULTS A normal CT or MRI scan was seen in 143 of 263 patients (54.3 %). Abnormal imaging findings were grouped into the following four categories: (a) inflammatory findings: leptomeningeal involvements (44), basal meningeal enhancements (30), cranial nerve involvements (14), spinal nerve roots enhancement (8), brain abscesses (7), granulomas (6), and arachnoiditis (4). (b) White-matter involvement: white-matter involvement (32) with or without demyelinating lesions (7). (c) Vascular involvement: vascular involvement (42) mostly with chronic cerebral ischemic changes (37). (d) Hydrocephalus/cerebral edema: hydrocephalus (20) and brain edema (40). On multivariate logistic regression analysis duration of symptoms since the onset (OR 1.007; 95 % CI 1-28, p = 0.01), polyneuropathy and radiculopathy (OR 5.4; 95 % CI 1.002-1.013, p = 0.044), cerebrospinal fluid (CSF)/serum glucose rate (OR 0.001; 95 % CI 000-0.067, p = 0.001), and CSF protein (OR 2.5; 95 % CI 2.3-2.7, p = 0.0001) were associated with diffuse inflammation. CONCLUSIONS In this study, 45 % of neurobrucellosis patients had abnormal neuroimaging findings. The duration of symptoms, polyneuropathy and radiculopathy, high CSF protein level, and low CSF/serum glucose rate were associated with inflammatory findings on imaging analyses.

Abstract
Polyradiculopathy (PRP) is a rare but serious neurologic complication of cytomegalovirus (CMV) in patients with acquired immunodeficiency syndrome (AIDS). We herein report three cases of CMV PRP in patients with AIDS. Although providing a prompt diagnosis and initiating anti-CMV therapy may achieve clinical improvements, administering single-drug treatment may result in virologic failure. Therefore, introducing antiretroviral therapy is a key step for improving the treatment outcomes of CMV PRP.

Abstract
Peripheral nerve disorders are associated with all stages of HIV infection. Distal sensory polyneuropathy is characterised by often-disabling pain that is difficult to treat. It is prevalent in both high-income and low-income settings. In low-income settings, use of potentially neurotoxic antiretrovirals, which are inexpensive and widely available, contributes substantially to incidence. Research has focused on identification of factors that predict risk of distal sensory polyneuropathy and elucidation of the multifactorial mechanisms behind pathogenesis. Sensorimotor polyneuropathies and polyradiculopathies are less frequent than distal sensory polyneuropathy, but still occur in low-income settings and have potentially devastating consequences. However, many of these diseases can be treated successfully with a combination of antiretroviral and immune-modulating therapies. To distinguish between peripheral nerve disorders that have diverse, overlapping, and frequently atypical presentations can be challenging; a framework based on a clinicoanatomical approach might assist in the diagnosis and management of such disorders.

Abstract
Peripheral neuropathies are the most common neurological manifestations occurring in HIV-infected individuals. Distal symmetrical sensory neuropathy is the most common form encountered today and is one of the few that are specific to HIV infection or its treatment. The wide variety of other neuropathies is akin to the neuropathies seen in the general population and should be managed accordingly. In the pre-ART era, neuropathies were categorized according to the CD4 count and HIV viral load. In the early stages of HIV infection when CD4 count is high, the inflammatory demyelinating neuropathies predominate and in the late stages with the decline of CD4 count opportunistic infection-related neuropathies prevail. That scenario has changed with the present almost universal use of ART (antiretroviral therapy). Hence, HIV-associated peripheral neuropathies are better classified according to their clinical presentations: distal symmetrical polyneuropathy, acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), mononeuropathies, mononeuropathies multiplex and cranial neuropathies, autonomic neuropathy, lumbosacral polyradiculomyelopathy, and amyotrophic lateral sclerosis (ALS)-like motor neuropathy. Treated with ART, HIV-infected individuals are living longer and are at a higher risk of metabolic and age-related complications; moreover they are also prone to the potentially neurotoxic effects of ART. There are no epidemiological data regarding the incidence and prevalence of the peripheral neuropathies. In the pre-ART era, most data were from case reports, series of patients, and pooled autopsy data. At that time the histopathological evidence of neuropathies in autopsy series was almost 100%. In large prospective cohorts presently being evaluated, it has been found that 57% of HIV-infected individuals have distal symmetrical sensory neuropathy and 38% have neuropathic pain. It is now clear that distal symmetrical sensory neuropathy is caused predominantly by the ART's neurotoxic effect but may also be caused by the HIV itself. With a sizeable morbidity, the neuropathic pain caused by distal symmetrical sensory neuropathy is very difficult to manage; it is often necessary to change the ART regimen before deciding upon the putative role of HIV infection itself. If the change does not improve the pain, there are few options available; the most common drugs used for neuropathic pain are usually not effective. One is left with cannabis, which cannot be recommended as routine therapy, recombinant human nerve growth factor, which is unavailable, and topical capsaicin with its side-effects. Much has been done to and learned from HIV infection in humans; HIV-infected individuals, treated with ART, are now dying mostly from cardiovascular disease and non-AIDS-related cancers. It hence behooves us to find new approaches to mitigate the residual neurological morbidity that still impacts the quality of life of that population.

Abstract
Among the human herpes viruses, three are neurotropic and capable of producing severe neurological abnormalities: herpes simplex virus type 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV). Both the acute, primary infection and the reactivation from the site of latent infection, the dorsal sensory ganglia, are associated with severe human morbidity and mortality. The peripheral nervous system is one of the major loci affected by these viruses. The present review details the virology and molecular biology underlying the human infection. This is followed by detailed description of the symtomatology, clinical presentation, diagnosis, course, therapy, and prognosis of disorders of the peripheral nervous system caused by these viruses.

Abstract
The human immunodeficiency virus (HIV) epidemic, now entering its fourth decade, affects approximately 33 million people living in both developed and resource-limited countries. Neurological complications of the peripheral nervous system are common in HIV-infected patients, and neuromuscular pathology is associated with significant morbidity. Peripheral neuropathy is the most common neuromuscular manifestation observed in HIV/AIDS, and in the antiretroviral era, its prevalence has increased. The purpose of this review was to describe the clinical spectrum of neuromuscular disorders in the setting of HIV infection and to provide an approach to diagnosis and management.

Abstract
Polyradiculopathies are uncommon peripheral nervous system syndromes that result from a variety of conditions. The clinical manifestations are variable but often include symmetric or asymmetric distal and proximal weakness with a variable degree of sensory loss and reduction or loss of reflexes. The most common cause of an acute polyradiculopathy is acute inflammatory demyelinating polyradiculopathy (also known as Guillain-Barré syndrome); however, other inflammatory, infectious, or neoplastic causes can present with similar features. Chronic polyradiculopathies include chronic inflammatory demyelinating polyradiculopathy as well as paraprotein-related syndromes and other inflammatory and infectious causes. Evaluation using a combination of serologic studies, electrodiagnostic testing, and CSF evaluation can help to identify the underlying etiology and implement the appropriate treatment. This article reviews the approach to patients with suspected polyradiculopathy and the features of the more common causes of acute and chronic polyradiculopathies.

Abstract
PURPOSE OF REVIEW The purpose of this review is to address bacterial, viral, and other infectious causes of neuropathy or neuronopathy, with an emphasis on clinical manifestations and treatment. RECENT FINDINGS Most infectious neuropathies have been well described for some time and treatments are well established. An exception is HIV-associated distal symmetric polyneuropathy, which is an area of active research. Current work in this area focuses on epidemiology, risk factors, and underlying mechanisms. SUMMARY Infectious diseases are an important part of the differential diagnosis of peripheral nerve disorders because they are among the most amenable to treatment. However, diagnosis of infectious peripheral neuropathy may be challenging because of variability in a number of factors, including the pattern of deficits, geographic distribution of pathogens, length of time from the onset of infection to the development of neuropathy, and mechanism of nerve injury.

Abstract
Diffuse infiltrative lymphocytosis syndrome (DILS) is a hyperimmune reaction against HIV. It leads to MHC-restricted clonal expansion of CD8 T cells characterized by circulating CD8 hyperlymphocytosis and CD8 T-cell infiltration in organs. Our patient presented with painful lumbosacral radiculoplexus neuropathy and tested positive for HIV. Nerve biopsy showed large collections of CD8 lymphocytes suspicious for lymphoma. Symptoms, signs, and repeat biopsy improved with antiretroviral treatment. The presentation and treatment response suggest that this case is localized DILS.

Abstract
The human immunodeficiency virus (HIV), the cause of AIDS, has infected an estimated 33 million individuals worldwide. HIV is associated with immunodeficiency, neoplasia, and neurologic disease. The continuing evolution of the HIV epidemic has spurred an intense interest in a hitherto neglected area of medicine, neuroinfectious diseases and their consequences. This work has broad applications for the study of central nervous system (CNS) tumors, dementias, neuropathies, and CNS disease in other immunosuppressed individuals. HIV is neuroinvasive (can enter the CNS), neurotrophic (can live in neural tissues), and neurovirulent (causes disease of the nervous system). This article reviews the HIV-associated neurologic syndromes, which can be classified as primary HIV neurologic disease (in which HIV is both necessary and sufficient to cause the illness), secondary or opportunistic neurologic disease (in which HIV interacts with other pathogens, resulting in opportunistic infections and tumors), and treatment-related neurologic disease (such as immune reconstitution inflammatory syndrome).

Abstract
Neuromuscular disorders are common in human immunodeficiency virus (HIV); they occur at all stages of disease and affect all parts of the peripheral nervous system. These disorders have diverse etiologies including HIV itself, immune suppression and dysregulation, comorbid illnesses and infections, and side effects of medications. In this article, we review the following HIV-associated conditions: distal symmetric polyneuropathy; inflammatory demyelinating polyneuropathy; mononeuropathy; mononeuropathy multiplex; autonomic neuropathy; progressive polyradiculopathy due to cytomegalovirus; herpes zoster; myopathy; and other, rarer disorders.

Abstract
Meningitis and myelitis represent common and very infrequent viral infections of the central nervous system, respectively. The number of cases of viral meningitis that occurs annually exceeds the total number of meningitis cases caused by all other etiologies combined. Focal central nervous system infections, such as occur in the spinal cord with viral myelitis, are much less common and may be confused with noninfectious disorders that cause acute flaccid paralysis. This article reviews some of the important clinical features, epidemiology, diagnostic approaches, and management strategies for patients with aseptic meningitis and viral myelitis. Particular focus is placed on the diseases caused by enteroviruses, which as a group account for most aseptic meningitis cases and many focal infections of the spinal cord.

Abstract
Lumbosacral radiculopathy is one of the most common disorders evaluated by neurologists and is a leading referral diagnosis for the performance of electromyography. Although precise epidemiologic data are difficult to establish, the prevalence of lumbosacral radiculopathy is approximately 3% to 5%, distributed equally in men and women. Degenerative spondyloarthropathies are the principal underlying cause of these clinical syndromes and are increasingly commonplace with age. Men are most likely to develop symptoms in their 40s, whereas women are affected most commonly between ages 50 and 60. The clinical presentation and initial management of lumbosacral radiculopathies of various etiologies are discussed.

Abstract
BACKGROUND The clinical and pathologic spectrum of Guillain Barre Syndrome (GBS) has expanded to include both demyelinating and axon loss forms. GBS may also have atypical presentations. For these reasons, clinicians are more likely to overlook unrelated disorders that mimic GBS. REVIEW SUMMARY In this article, the classic presentation and variants of GBS are briefly reviewed. Disorders that mimic GBS are reviewed in detail, including those caused by neurotoxins, heavy metals, chemical toxins, drugs, vasculitis, hereditary disorders, infections, critical illness, and myelopathy. Illustrative case studies accompany a number of the descriptions. CONCLUSIONS Failure to recognize the mimics of GBS can lead to erroneous diagnosis, inappropriate treatment, and significant morbidity. Appropriate diagnosis requires a combination of careful history and examination, and accurate interpretation of diagnostic testing.

Abstract
This article addresses the clinical presentations of different peripheral neuropathies. The topic is discussed briefly with emphasis on the most important clinical features. MR imaging of the peripheral nerves is a rapidly advancing field, and it is hoped that the basic understanding of the clinical presentations of peripheral neuropathies will encourage radiologists to get more involved in MR imaging of the peripheral nerves.

Abstract
Peripheral nerve complications occurring in patients with human immunodeficiency virus (HIV) infection are frequent and challenging. This review discusses these various complications according to the degree of advancement of HIV disease. Particular emphasis is placed upon emerging causes of neuropathy found in the context of HIV disease, such as infection with hepatitis C and human T-lymphotropic virus type I, as well as neuropathies related to antiretroviral medications.

Abstract
It is now more than two decades since the AIDS epidemic began with a cluster of Pneumocystis carinii pneumonia (PCP) in a community of homosexual men. Since then, many other infections have been characterized as opportunistic infections secondary to HIV infection. These include, but are not limited to, infections with Toxoplasma gondii, Cytomegalovirus (CMV), Mycobacterium avium complex (MAC), and Cryptococcus neoformans. Over the last two decades, there have been dramatic improvements in diagnosis, prevention and treatment of all these infections. As a result, in North America and Western Europe the rates of opportunistic infections secondary to AIDS have decreased substantially. We will review these common opportunistic infections below.

Abstract
Suppression of the immune system by human immunodeficiency virus (HIV) infection or immunosuppressive therapy following transplantation increases susceptibility to CNS infection. Examination of the level and type of immunosuppression, in addition to the clinical and radiologic findings at the time of diagnosis can aid the clinician in determining the most likely etiology of infection. This article discusses how suppression of the host immune status modifies the presentation and diagnosis of selected CNS infections and the recommended treatment for these infections.

Abstract
This study examined the clinical correlation between the presence of human cytomegalovirus (HCMV) pp67 mRNA in cerebrospinal fluid (CSF) and active HCMV central nervous system (CNS) disease in patients with human immunodeficiency virus type 1 (HIV-1). In total, 76 CSF specimens collected from 65 HIV-1-positive patients diagnosed with HCMV CNS disease, other non-HCMV-related CNS diseases, or no CNS disease were tested for the presence of HCMV pp67 mRNA using the NucliSens cytomegalovirus (CMV) pp67 assay (Organon Teknika, Durham, N.C.). The results were compared to those of a nested PCR for the detection of HCMV glycoprotein B DNA and to those obtained by viral culture (54 samples). CSF specimens collected from patients without HCMV CNS disease yielded the following results: pp67 assay negative, 62 of 62 specimens; culture negative, 41 of 41 specimens; and PCR negative, 56 of 62 specimens (6 specimens were positive). CSF specimens collected from patients with HCMV CNS disease yielded the following results: pp67 assay positive, 9 of 13 specimens; PCR positive, 13 of 13 specimens; and culture positive, 2 of 13 specimens. After resolution of the discordant results, the following positive and negative predictive values (PPV and NPV, respectively) for the diagnosis of HCMV CNS disease were determined. The PPV for PCR, pp67 assay, and culture were 68.4, 100, and 100%, respectively, and the NPV for PCR, pp67 assay, and culture were 100, 97.0, and 82. 7%, respectively. The sensitivities for DNA PCR, pp67 assay, and culture for the detection of HCMV were 100, 84.6, and 18%, respectively, and the clinical specificities were 90.5, 100, and 100%, respectively. This study indicates that the detection of HCMV pp67 mRNA in CSF has good correlation with active HCMV CNS disease, whereas CSF culture is insensitive and qualitative DNA PCR may detect latent nonreplicating virus in CSF from patients without HCMV CNS disease.

Abstract
Neurologic disease is commonly encountered in the population infected with human immunodeficiency virus type 1 (HIV-1). Although HIV-1 is responsible for many of these neurologic complications, other organisms will affect the nervous system as the immune deficiency state progresses. With the wide use of potent antiretroviral therapy, the mortality from and incidence of opportunistic infections (OIs) among persons with advanced HIV-1 infection has decreased. Nevertheless, these diseases are still seen frequently, especially among those with limited access to new antiretroviral therapies. Therefore, it remains important to recognize the most common OIs of the central nervous system (CNS) as well as primary CNS lymphoma, which will be the focus of this review.

Abstract
OBJECTIVE To evaluate the efficacy and safety of the foscarnet-ganciclovir combination in induction therapy (IT) and maintenance therapy (MT) for cytomegalovirus (CMV) central neurological disorders in HIV-infected patients. DESIGN An open pilot non-comparative multicentre study. METHODS Thirty-one patients with acute CMV encephalitis (CMVe) (n = 17) or CMV myelitis (CMVm) (n = 14) during the era before highly active antiretroviral therapy (HAART) received intravenous IT with foscarnet 90 mg/kg plus ganciclovir 5 mg/kg twice a day followed by MT. The primary endpoint was clinical efficacy, assessed at the end of the induction phase. RESULTS The foscarnet-ganciclovir combination in IT resulted in a 74% (23 out of 31 patients) clinical improvement or stabilization. Eight patients did not respond clinically. Side-effects leading to drug discontinuation occurred in 10 patients during IT. Among the 23 patients who qualified for the maintenance phase, CMV disease progressed in 10, with a median time to the first relapse of 126 days (range 64-264 days). Overall, the median survival time was 3 months [95% confidence interval (CI), 2-4 months]. CONCLUSION The combination of foscarnet and ganciclovir can safely be used for CMV central nervous system (CNS) infection, with an improvement or stabilization in 74% of patients. Life-long MT with this combination is recommended as long as the immune system is profoundly impaired.

Abstract
The syndrome of inflammatory subacute lumbosacral polyradiculoneuropathy (SLP) has been reported in acquired immunodeficiency syndrome (AIDS) patients in association with cytomegalovirus infection and is only partially amenable to anti-viral therapy. We report three cases of relatively benign inflammatory painful SLP in two non-AIDS, immunosuppressed patients and one who HIV-seroconversed at the time of clinical presentation. SLP developed: (1) in association with HIV seroconversion; (2) during ECHO virus infection in a patient with common variable immune deficiency; and (3) after a severe systemic infection that induced transient immunosuppression due to Epstein-Barr virus reactivation. This report expands the spectrum of viruses associated with acute and subacute lumbosacral polyradiculoneuropathy and may shed light on its possible pathogenesis.

Abstract
OBJECTIVE To review the neurologic manifestations of AIDS in patients who were admitted to Hospital Guilherme Alvaro (HGA) due to any clinical manifestation of the disease. DESIGN Case series. PATIENTS All HIV+ patients admitted to the Faculty Hospital (HGA) between July 96 and April 97 were included in this review. RESULTS From the 117 HIV+ patients admitted to hospitalization due to AIDS-related symptoms, 50 (42.7%) presented neurologic manifestations. The most prevalent of these was neurotoxoplasmosis (68%), but a variety of other neurologic diseases were observed. Only 36% of these 50 patients had neurological signs and symptoms as the main complaint for admission, 12% of the patients had at least complained of some neurologic dysfunction at the time of admission and 10% had no neurologic complaints at all. The remaining 42% (21 patients) only complained of neurologic manifestations of AIDS when specifically asked. CONCLUSIONS The prevalence of neurologic manifestations of AIDS is very high in patients admitted to hospital. Even in the absence of neurologic-related complaints, these patients have to be carefully questioned and examined in the search for an underlying neurologic complication which may present high morbidity and mortality.

Abstract
Cytomegalovirus (CMV) polyradiculopathy is a rare complication of AIDS in which ascending motor weakness, sensory loss and urinary retention are associated with polymorphonuclear pleocytosis and positive CMV polymerase chain reaction in the cerebrospinal fluid (CSF). We describe three patients with this syndrome. One patient's paresis improved after ganciclovir therapy. Another patient deteriorated despite foscarnet treatment, but improved after ganciclovir was added. The third patient died from ascending paralysis despite ganciclovir-foscarnet combination. Reviewing the literature, we conclude that antiviral treatment reduced mortality from 100 to 22%. In patients with ascending paralysis treatment, failure may be caused by viral drug resistance, at least in some patients. Risk factors for treatment failure are preceding monotherapy for other CMV diseases or persistent CSF pleocytosis on serial CSF analysis. We suggest that these patients should therefore be treated with the alternative drug or a ganciclovir-foscarnet combination therapy.

Abstract
BACKGROUND Herpesvirus infections of the central nervous system are often severe but are fortunately rare. The incidence of these infections has however, increased in recent years as a consequence of an increase in the number of immune-compromised individuals. New diagnostic procedures have improved our ability to diagnose these infections and herpesviruses may yet be implicated as the cause of further neurological diseases with no known aetiology. Methodological standards for selection and evaluation of patient materials are essential to the provision of reliable diagnosis, yet few studies have addressed this important issue. OBJECTIVES To describe and define methodological standards and reference methodology for diagnosis of herpesvirus infections of the CNS. STUDY DESIGN Information gathered by literature review. RESULTS Only for herpes simplex encephalitis is there sufficient data to allow the definition of reference methodology. Good methodological standards exist but few studies have adhered to these standards. As methods for the detection of specific intrathecal antibody synthesis are well established yet under-used in diagnostic virology, the principle of these measurements is reviewed in some detail. CONCLUSIONS Herpesvirus infections of the CNS are of increasing importance. High quality, multi-centre studies are needed to establish the value of the new diagnostic test procedures if further improvement in the diagnostic sensitivity and specificity of these procedures is to be achieved.

Abstract
OBJECTIVES To describe the abnormalities in CSF from HIV infected patients with acute lumbosacral polyradiculopathy (ALP) caused by cytomegalovirus (CMV) infection. METHODS Retrospective case notes and laboratory records were reviewed for 17 consecutive patients with CMV associated ALP admitted to specialist HIV/AIDS units at UCL Hospitals and Chelsea and Westminster Hospital. RESULTS Infection with CMV was confirmed by detection of CMV DNA by polymerase chain reaction amplification in 15 patients (all of whom were negative by culture), by culture in one patient, and by objective clinical response to anti-CMV treatment in one patient. Only nine patients had a CSF pleocytosis 28-1142 (median 150) cells/mm3; in seven there was a polymorphonuclear (PMN) leucocyte preponderance. Protein concentrations in CSF were moderately or considerably raised in 13 patients; CSF: plasma glucose ratios were < or = 50% in five patients. Two patients had no pleocytosis, normal CSF: plasma glucose, and normal or near normal protein values. CONCLUSIONS Abnormalities in CSF in CMV associated ALP are varied: only 50% of patients have a "typical" PMN preponderant pleocytosis. The diagnosis of this condition should not rely on demonstration of a PMN preponderant pleocytosis, but on identification of CMV DNA in CSF and the exclusion of other opportunistic infections and lymphoma in order that specific anti-CMV treatment may be instituted.

Abstract
A wide spectrum of central and peripheral nervous system abnormalities may be associated with HIV infection. These disorders may be caused by HIV infection, result as secondary complications related to immunosuppression, or be a neurotoxic effect of therapeutic agents. The range of neurologic disorders includes dementia, focal cerebral mass lesions, myelopathy, peripheral neuropathies, and myopathy. Early diagnosis and therapy is critical, and may result in substantial improvement in patients' quality and quantity of life. This article reviews the approach to differential diagnosis of these neurologic disorders and presents theories of pathogenesis and current approaches to treatment.

Abstract
We studied whether there was an association between nerve conduction studies (NCS), CSF, and CD4-T lymphocyte parameters in a large cohort of HIV positive individuals. Two hundred and twenty-eight HIV positive individuals underwent motor and sensory nerve conduction studies, CSF evaluation, peripheral CD4-T lymphocyte count, and neurologic evaluation to determine the presence or absence of peripheral neuropathy. We compared NCS of HIV positive subjects with and without abnormal CSF parameters in the entire cohort. We also compared CSF parameters in a subset of CD4-matched patients with and without neuropathy. CSF abnormalities (in excess of laboratory norms) occurred frequently in the entire study group. There was no statistically significant relationship between NCS and CSF parameters. In addition, there was no significant difference in the CSF findings in the group of patients with clinical neuropathy compared to the group without neuropathy. However, there was an association (p < 0.05) between lower CD4 counts and NCS parameters. In general, abnormal CSF findings are not associated with deteriorating peripheral nerve function in HIV infected patients and are just as likely to be found in an HIV positive patient whether or not a peripheral neuropathy is present.

Abstract
We studied three patients with myelomeningoradiculitis caused by Borrelia burgdorferi, herpes zoster virus or cytomegalovirus infection. All patients underwent MRI of the spinal cord with gadolinium-DTPA and showed enhancing lesions of the spinal cord or nerve roots that correlated with clinical signs. Gadolinium-DTPA enhancement may visualize lesions that suggest an inflammation associated with blood-brain-barrier alteration and indicate the diagnosis before serological results are available.

Abstract
Cytomegalovirus polyradiculopathy, a late complication of HIV infection, is characterized by lower extremity weakness, urinary retention, and sacral dysesthesias. We describe four patients (mean CD4 T-cell count = 25 cells/mm3) who developed this "infectious cauda equina syndrome." The characteristic cerebrospinal fluid (CSF) findings, notably atypical for a viral infection, included polymorphonuclear leukocytosis (mean white blood cell count = 1512 cells/mm3, 72% polymorphonuclear leukocytes), elevated protein level (mean = 370 mg/dl), and hypoglycorrhacia (mean = 28 mg/dl). Physicians who treat patients with HIV should be familiar with this syndrome because early intervention, prior to microbiologic confirmation, provides the best hope for improving neurologic function.

Abstract
We report 4 autopsy-proven cases of cytomegalovirus ventriculoencephalitis (CMV-VE) and a further case with dramatic clinical and radiological response to ganciclovir therapy. The diagnoses were based upon clinical features, cerebrospinal fluid (CSF) examination and either brain computerized tomography (CT) or magnetic resonance imaging (MRI), and confirmed by autopsy findings in 4 cases. All patients had previously had an AIDS-defining condition. CMV retinitis was diagnosed in 3 patients, 2 of them before the onset of encephalitis. CMV viremia was present in 4 patients. Examination of CSF demonstrated elevated protein and hypoglycorachia in all cases. CSF culture was negative for CMV in 3 of 3 patients. Periventricular enhancement was detected by MRI in 2 of 3 patients, but in only 1 of 5 patients by CT. Three patients received ganciclovir and 2 patients foscarnet therapy. All 4 patients died. Pathologic examination revealed periventriculitis with ependymal necrosis and CMV intranuclear inclusion bodies all 4 patients. One showed a marked neurological improvement and radiological resolution by MRI after 4 weeks of ganciclovir therapy. We conclude that CMV-VE should be suspected in HIV-infected patients who present with altered neurological status, CMV viremia or retinitis, hypoglycorachia and ventriculitis as demonstrated by MRI. Although more effective therapy is needed, ganciclovir may be beneficial, as shown in one of our patients.
