Abstract
Key Clinical Message Toxoplasmosis-related huge brain lesions may require decompressive craniectomy and lesion excision to avoid brain damage. In this situation, injectable cotrimoxazole is a better choice for treatment. Abstract Toxoplasma gondii is a worldly distributed obligate intracellular protozoa. Toxoplasmosis is a prevalent opportunistic infection in HIV-infected people, but it was rarely recorded prior to the identification of HIV infection. Here, we report a toxoplasmosis brain lesion in an Iranian HIV-positive patient. A 45-year-old woman with a complaint of malaise was referred to the Valiasr Hospital in Arak city. In her past clinical history, the patient had a history of anemia, deep vein thrombosis (DVT), and positive HIV. The patient was informed of the diagnosis of massive brain toxoplasmosis as a definite diagnosis. The patient was then taken to the operating room for a left decompressive craniectomy, during which the ensuing brain lesion was excised. After a few days, she was discharged from the hospital in good condition and without any complications.

Unveiling of brain transcriptome of masked palm civet (Paguma larvata) with chronic infection of Toxoplasma gondii. Parasit Vectors 2022; 15:263. [PMID: 35871661 PMCID: PMC9308931 DOI: 10.1186/s13071-022-05378-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Accepted: 06/15/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The aim of this study was to gain an understanding of the transcriptomic changes that occur in a wild species when infected with Toxoplasma gondii. The masked palm civet, an artifically domesticated animal, was used as the model of a wild species. Transcriptome analysis was used to study alterations in gene expression in the domesticated masked palm civet after chronic infection with T. gondii. METHODS Masked palm civets were infected with 105 T. gondii cysts and their brain tissue collected after 4 months of infection. RNA sequencing (RNA-Seq) was used to gain insight into the spectrum of genes that were differentially expressed due to infection. Quantitative reverse-transcription PCR (qRT-PCR) was also used to validate the level of expression of a set of differentially expressed genes (DEGs) obtained by sequencing. RESULTS DEGs were screened from the sequencing results and analyzed. A total of 2808 DEGs were detected, of which 860 were upregulated and 1948 were downregulated. RNA-Seq results were confirmed by qRT-PCR. DEGs were mainly enriched in cellular process and metabolic process based on gene ontology enrichment analysis. Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that transcriptional changes in the brain of infected masked palm civets evolved over the course of infection and that DEGs were mainly enriched in the signal transduction, immune system processes, transport and catabolic pathways. Finally, 10 essential driving genes were identified from the immune signaling pathway. CONCLUSIONS This study revealed novel host genes which may provide target genes for the development of new therapeutics and detection methods for T. gondii infection in wild animals.

[PMID: 34512827 DOI: 10.5847/wjem.j.1920-8642.2021.04.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 07/08/2021] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND To explore the clinical manifestations, diagnosis, and treatment of patients with acquired immunodeficiency syndrome (AIDS) complicated with drug-induced erythroderma. METHODS The clinical data of 12 AIDS patients with drug-induced erythroderma in our hospital were retrospectively analyzed. The general information, offending medications, complications, modified severity-of-illness score for toxic epidermal necrolysis (SCORTEN) scores, and disease outcome spectrums were analyzed. RESULTS Drug-induced erythroderma was mostly caused by antiviral drugs, antituberculosis drugs, antibiotics, traditional Chinese medicine, and immune checkpoint inhibitors. The spectrum of sensitizing drugs was broad, the clinical situation was complex, and infections were common. The affected areas were greater than 40% body surface area in all patients. The modified SCOTERN score averaged 3.01±0.99. All patients were treated with glucocorticoids, and nine patients were treated with intravenous immunoglobulin (IVIG) pulse therapy at the same time. The average time to effectiveness was 7.08±2.23 days, and the average hospital stay was 17.92±8.46 days. Eleven patients were cured, and one patient died of secondary multiple infections, who had a modified SCORTEN score of 5 points. The mortality rate in this study was 8.3%. CONCLUSIONS The clinical situation of AIDS patients with drug-induced erythroderma in hospitalized patients is complex and the co-infection rate is high. The use of modified SCORTEN score may objectively and accurately assess the conditions, and the use of glucocorticoid combined with IVIG therapy may improve the prognosis.
