Metabolomic Profiling Reveals Common Metabolic Alterations in Plasma of Patients with Toxoplasma Infection and Schizophrenia. Genes (Basel) 2022; 13:genes13081482. [PMID: 36011393 PMCID: PMC9408728 DOI: 10.3390/genes13081482] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/17/2022] [Accepted: 08/18/2022] [Indexed: 11/17/2022] Open
Abstract
Toxoplasma gondii is an opportunistic protozoan parasite known to affect the human brain. The infection has been associated with an increased incidence of schizophrenia; however, the link between the two conditions remains unclear. This study aimed to compare the plasma metabolome of schizophrenia and non-schizophrenia subjects with or without Toxoplasma infection. Untargeted metabolomic profiling was carried out by liquid chromatography-mass spectrometry. Elevation of the α-hydroxyglutaric acid level and reduced adenosine monophosphate, inosine, hypoxanthine and xanthine were found in the subjects with either toxoplasmosis or schizophrenia alone. These results suggest that purine catabolism is a common metabolic alteration in Toxoplasma infection and schizophrenia. The roles of these metabolites on the pathogenesis of schizophrenia in relation to Toxoplasma infection warrant further studies.

A Review on the Prevalence of Toxoplasma gondii in Humans and Animals Reported in Malaysia from 2008-2018. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E4809. [PMID: 32635389 PMCID: PMC7369958 DOI: 10.3390/ijerph17134809] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 04/18/2020] [Accepted: 04/25/2020] [Indexed: 12/17/2022]
Abstract
Toxoplasmosis is a disease caused by the protozoan parasite Toxoplasma gondii (T. gondii). Human toxoplasmosis seroprevalence in Malaysia has increased since it was first reported in 1973 as shown in previous reviews of 1991 and 2007. However, over a decade since the last review, comprehensive data on toxoplasmosis in Malaysia is lacking. This work aimed at reviewing articles on toxoplasmosis research in Malaysia in order to identify the research gaps, create public awareness, and efforts made so far and proffer management options on the disease. The present review examines the available published research articles from 2008 to 2018 related to toxoplasmosis research conducted in Malaysia. The articles reviewed were retrieved from nine credible databases such as Web of Science, Google Scholar, ScienceDirect, PubMed, Scopus, Springer, Wiley online library, Ovid, and Cochrane using the keywords; Malaysia, toxoplasmosis, Toxoplasma gondii, toxoplasma encephalitis, seroprevalence, human immunodeficiency virus (HIV) patients, pregnant women, genotype strain, anti-toxoplasma antibodies, felines, and vaccine. The data highlighted seropositive cases from healthy community members in Pangkor Island (59.7%) and among migrant workers (57.4%) at alarming rates, as well as 42.5% in pregnant women. Data on animal seroprevalence were limited and there was no information on cats as the definitive host. Genetic characterization of Toxoplasma gondii from HIV patients; pregnant women, and domestic cats is lacking. This present review on toxoplasmosis is beneficial to researchers, health workers, animal health professionals, and policymakers. Therefore, attention is required to educate and enlighten health workers and the general public about the risk factors associated with T. gondii infection in Malaysia.

Abstract
Toxoplasma gondii is an opportunistic infection that often presents in the setting of acquired immunodeficiency syndrome. The infection can cause severe and potentially fatal encephalitis because of the reactivation of latent infections in the setting of immune suppression. Diagnosing toxoplasmosis encephalitis (TE) in immunocompromised patients often is difficult because the signs and symptoms can be nonspecific, but making a diagnosis of TE is even more challenging in a patient who is not known to have human immunodeficiency virus/acquired immunodeficiency syndrome and shows no other signs of being immunocompromised. Early diagnosis and treatment can result in rapid radiologic and clinical improvement; however, no studies exist that evaluate the utility of functional rehabilitation for patients diagnosed with TE. Although previous studies report a good prognosis for patients who receive antibiotic treatment, they do not discuss the extent to which functional abilities lost during the infection are returned after their treatment. We discuss a case of stroke-like presentation of cerebral TE in a patient whose human immunodeficiency virus status was previously unknown and report the functional improvements that were made during acute inpatient rehabilitation.
