Abstract
AIM Mental disorders and HIV are the main contributors to the increase in years lived with disability rates per person in sub-Saharan Africa. A complex inter-relationship exists between HIV and mental illness, especially in a region with a high HIV prevalence. We examined the duration of untreated psychosis (DUP), and the nature of psychotic and cognitive symptoms in people with first episode psychosis (FEP) living with and without HIV. METHODS Adults aged between 18 and 45 years were assessed using a clinical interview, physical examination and several psychiatric tools. These included the Mini International Neuro-psychiatric Interview to confirm psychosis, Positive and Negative Syndrome Scale, International HIV Dementia Scale and other scales to measure symptom variables. HIV ELISA was used for HIV serology testing, with measures being carried out within 6 weeks of the first presentation. RESULTS Of the 172 people presenting with FEP, 36 (21%) had comorbid HIV, those with both being older and more likely to be female (p < .001). Clinically, participants with FEP and HIV scored lower on the positive subscale (p = .008). There were no statistically significant differences for DUP or cognitive screening. Of those living with HIV and FEP (n = 36) comorbidity, nine were newly diagnosed with HIV at the time of the study. CONCLUSION Individuals presenting with FEP and comorbid HIV were older, female and reported more mood symptoms. The identification of nine new HIV infections also reflects the ongoing need to test for HIV in people presenting with severe mental illness.

Abstract
BACKGROUND Psychiatric morbidity in human immunodeficiency virus (HIV) patients is being studied all over the world. There is paucity of Indian literature particularly in asymptomatic HIV individuals. AIM The aim of the following study is to establish the prevalence and the determinants of psychiatric morbidity in asymptomatic HIV patients. MATERIALS AND METHODS A cross-sectional study was undertaken to assess psychiatric morbidity as per ICD-10 dacryocystorhinostomy criteria in 100 consecutive asymptomatic seropositive HIV patients and an equal number of age, sex, education, economic and marital status matched HIV seronegative control. All subjects were assessed with the general health questionnaire (GHQ), mini mental status examination, hospital anxiety and depression scale (HADS) and sensation seeking scale (SSS) and the scores were analyzed statistically. RESULTS Asymptomatic HIV positive patients had significantly higher GHQ caseness and depression but not anxiety on HADS as compared to HIV seronegative controls. On SSS asymptomatic HIV seropositive subjects showed significant higher scores in thrill and adventure seeking, experience seeking and boredom susceptibility as compared to controls. HIV seropositive patients had significantly higher incidence of total psychiatric morbidity. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. CONCLUSION Psychiatric morbidity is higher in asymptomatic HIV patients when compared to HIV seronegative controls. Among the individual disorders, alcohol dependence syndrome, sexual dysfunction and adjustment disorder were significantly increased compared with HIV seronegative controls. High sensation seeking and substance abuse found in HIV seropositive patients may play a vital role in engaging in high-risk behavior resulting in this dreaded illness.

Abstract
Our understanding of the vast collection of microbes that live on and inside us (microbiota) and their collective genes (microbiome) has been revolutionized by culture-independent "metagenomic" techniques and DNA sequencing technologies. Most of our microbes live in our gut, where they function as a metabolic organ and provide attributes not encoded in our human genome. Metagenomic studies are revealing shared and distinctive features of microbial communities inhabiting different humans. A central question in psychiatry is the relative role of genes and environment in shaping behavior. The human microbiome serves as the interface between our genes and our history of environmental exposures; explorations of our microbiomes thus offer the possibility of providing new insights into our neurodevelopment and our behavioral phenotypes by affecting complex processes such as inter- and intra personal variations in cognition, personality, mood, sleep, and eating behavior, and perhaps even a variety of neuropsychiatric diseases ranging from affective disorders to autism. Better understanding of microbiome-encoded pathways for xenobiotic metabolism also has important implications for improving the efficacy of pharmacologic interventions with neuromodulatory agents.

Abstract
Over 60,000 Canadians are infected with human immunodeficiency virus (HIV). Greater than 50% of these individuals will develop a neurological disorder despite the availability of highly active antiretroviral therapy. HIV causes nervous system disease at all stages of infection with adverse effects on quality of life, adherence to medications, employment and survival. These disorders include opportunistic infections in addition to distinct HIV-associated neurological syndromes and undesirable treatment-related effects. The latter two groups of disorders are often undiagnosed and untreated in both adolescents and adults. Direct HIV infection of central nervous system causes HIV-associated dementia, which is a progressive subcortical dementia. HIV infection of the peripheral nervous system produces a painful sensory neuropathy termed distal sensory polyneuropathy, which may be exacerbated by several antiretroviral drugs. Other important HIV-induced neurological disorders include vacuolar myelopathy and an increased risk of seizures. Future issues that will confound the presentation and treatment of HIV-induced nervous system disorders include the increasing prevalence of drug-resistant HIV strains, increasing age of HIV-infected patients, hepatitis C virus co-infection and the Immune Reconstitution Inflammatory Syndrome. Herein, we review the clinical presentations, underlying pathogenesis and treatments of this burgeoning group of neurological disorders.

Abstract
Almost 65 million people worldwide have been infected with HIV since it was first identified in the early 1980s. Neurologic disorders associated with HIV type 1 affect between 40% and 70% of infected individuals. The most significant of these disorders include HIV-associated neurocognitive disorder, which comprises HIV-associated dementia, mild neurocognitive disorder, and asymptomatic neurocognitive impairment. Despite the availability of combination antiretroviral therapy, HIV-related central nervous system disorders continue to represent a substantial personal, economic, and societal burden. This review summarizes the clinical manifestations, diagnosis, treatment, and pathogenesis of the primary HIV-associated central nervous system disorders.

Abstract
Neurotoxic viral proteins released from HIV-infected cells are believed to play a major role in the pathogenesis of the dementia displayed in a significant number of AIDS patients. HIV-1 associated neuropathology severely affects dopaminergic regions of the brain. Growing evidence indicates that HIV-1 neurotoxic proteins, such as Tat may affect the function of the dopamine transmission system. In turn, molecular components of dopamine neurotransmission may participate in a complex network of Tat-induced cell responses which result in neurodegeneration. In this study we investigated whether D1 dopamine receptors are involved in the mechanism of Tat neurotoxicity in primary rat neuronal cell cultures. We found that in rat midbrain cell cultures, which express significant levels of D1 dopamine receptors, the specific D1 antagonist SCH 23390 attenuates the cell death caused by HIV-1 Tat. In rat hippocampal cell cultures, where the expression of D1 receptors is low, SCH 23390 did not change the toxicity of Tat. Thus, the protective effect of SCH 23390 in rat primary neuronal cell cultures is a function of the level of D1 receptor protein expression. Our results provide further evidence for the involvement of the dopaminergic transmission system in the mechanism of HIV-1 Tat neurotoxicity.

Abstract
This study aims to detect different psychopathological dimensions in first-episode psychoses with different underlying causes. We evaluated 22 subjects with first-episode psychosis, who differed in biological variables (HIV-positive versus HIV-negative) and who were compared by using the Structured Clinical Interview for DSM-III-Reviewer, the 18-item Brief Psychiatric Rating Scale (BPRS), the 17-item Hamilton Depression Rating Scale, the 14-item Hamilton Anxiety Rating Scale and the Mini-Mental State Examination. HIV-positive subjects had higher mean scores on the global BPRS and on the paranoid Positive and Negative Syndrome Scale subscale compared with HIV-negative subjects. Conversely, higher prevalence of affective and anxious symptoms was found in the HIV-negative patients in comparison to HIV-positives. HIV-positives had significantly greater attention/concentration impairment than HIV-negative persons. In conclusion, taking into account psychopathological dimensions may help psychiatrists in clinical decision-making regarding the differential diagnosis of psychotic symptoms. The psychopathological pattern of first-episode psychosis in HIV-positive patients may represent an 'elementary model' of acute psychosis characterized by paranoid delusions in the absence of the usual affective symptoms.

Abstract
Human immunodeficiency virus type 1 (HIV-1) infection is associated with psychiatric complications including cognitive impairment, affective disorders, and psychosis. Previous studies have revealed a disturbed kynurenine metabolism in these patients leading to increased levels of neuroactive compounds acting at glutamatergic neurotransmission. Kynurenic acid (KYNA), one of these metabolites is a glutamate-receptor antagonist, preferentially blocking the glycine site of the N-methyl-d-aspartate (NMDA) receptor. Increased levels of brain KYNA have been suggested to induce a NMDA receptor hypofunction that is associated with psychotic symptoms. In the present study, we analyze the concentration of KYNA in the cerebrospinal fluid (CSF) from HIV-1 infected patients (n=22), including HIV-1 infected patients with psychotic symptoms (n=8) and HIV-1 infected patients without psychiatric symptoms (n=14). We found that HIV-1 infected patients had significantly higher median concentration of CSF KYNA (3.02nM) compared to healthy controls (1.17nM). Furthermore, CSF KYNA levels were significantly elevated in HIV-1 infected patients with psychotic symptoms (4.54nM) compared to patients with HIV-1 without psychiatric symptoms (2.28nM). Present results indicate that increased levels of CSF KYNA may be associated with development of psychotic symptoms in HIV-1 infected patients.

Abstract
Since the acquired immune deficiency syndrome (AIDS) was first recognized in 1981, more than 25 million individuals have died from complications of the human immunodeficiency virus (HIV) infection. The introduction of highly active antiretroviral therapy (HAART) in 1995 has resulted in a significantly decreased incidence rate of AIDS in the developed world. As HAART led to considerable improvements in survival for patients with HIV infection, HIV-neurotropically associated neuropsychiatric disorders have become an increasingly important challenge for clinical medicine. This article gives an overview of epidemiology, clinical features, diagnosis, and therapy of HIV-induced cognitive-motor impairments including HIV-associated dementia complex, organic mood disorders and psychosis.

Abstract
Neuropsychiatric complications of human immunodeficiency virus (HIV) infection or acquired immune deficiency syndrome (AIDS) may present clinically as acute or chronic organic brain syndrome, or mimic functional psychiatric diseases. Among such psychiatric diseases, mania tends to occur with increased frequency after the onset of AIDS. We report a case in which manic manifestations were noted before the diagnosis of AIDS. The patient had no past or family history of mood disorders, but had risk factors for HIV infection. He had a rapid downhill course from initial manic symptoms to depression, dementia and then death within 10 months. Such rapid cognitive deterioration into AIDS dementia after mania is consistent with previous reports. Cases like this will become more common with spread of the AIDS pandemic in Asian regions, including Taiwan. Clinicians should be mindful of HIV infection/AIDS as a differential diagnosis in patients with manic episodes and risk factors for HIV infection.

Abstract
The basal ganglia, structures rich in the neurotransmitter dopamine, are primarily affected during human immunodeficiency virus (HIV) infection. The authors measured levels of dopamine and its metabolites, homovanillic acid and 3,4-dihydroxyphenylacetic acid, in brains of uninfected and simian immunodeficiency virus (SIV)-infected rhesus monkeys during the asymptomatic stage of the infection. Moreover, the authors investigated changes in cyclic adenosine monophosphate (cAMP) and cAMP response element-binding protein (CREB), two factors involved in the signaling pathway of dopamine. The brain regions examined were the nucleus accumbens and the corpus amygdaloideum, which are limbic structures of the basal ganglia that are involved in the pathophysiology of psychiatric disorders and substance abuse. Dopamine content was reduced in both regions of SIV-infected monkeys compared to uninfected animals. Moreover, dopamine deficits were associated with a decrease in expression of total CREB. Intracellular concentrations of cAMP were decreased in nucleus accumbens and remained unchanged in corpus amygdaloideum of SIV-infected macaques. Changes in dopamine signaling were not related to pathology or viral load of the investigated animals. The results suggest that dopamine defects precede neurologic deficits and implicate dysfunction of the dopaminergic system in the etiopathogenesis of HIV dementia. Therefore, affective complications in HIV subjects should not be interpreted only as reactive psychological changes. The alterations in the mesolimbic dopaminergic system during asymptomatic stage of SIV infection implicate a biological background for psychiatric disorders in HIV infection.
