Project description:We report a fatal case of disseminated acanthamebiasis caused by Acanthamoeba lenticulata (genotype T5) in a 39-year-old heart transplant recipient. The diagnosis was based on skin histopathologic results and confirmed by isolation of the ameba from involved skin and molecular analysis of a partial 18S rRNA gene sequence (DF3).

Fatal disseminated aspergillosis in an immunocompetent patient with COVID-19 due to Aspergillus ochraceus.

Project description:Aspergillus infection is a well-known complication of severe influenza and severe acute respiratory syndrome coronavirus (SARS-CoV), and these infections have been related with significant morbidity and mortality even when appropriately diagnosed and treated. Recent studies have indicated that SARS-CoV-2 might increase the risk of invasive pulmonary aspergillosis (IPA). Here, we report the first case of Aspergillus ochraceus in a SARS-CoV-2 positive immunocompetent patient, which is complicated by pulmonary and brain infections. Proven IPA is supported by the positive Galactomannan test, culture-positive, and histopathological evidence. The patient did not respond to voriconazole, and liposomal amphotericin B was added to his anti-fungal regimen. Further studies are needed to evaluate the prevalence of IPA in immunocompetent patients infected with SARS-CoV-2. Consequently, testing for the incidence of Aspergillus species in lower respiratory secretions and Galactomannan test of COVID-19 patients with appropriate therapy and targeted anti-fungal therapy based on the primary clinical suspicion of IPA are highly recommended.

Disseminated Mycobacterium genavense Infection in Patient with Adult-Onset Immunodeficiency.

Project description:We report a case of disseminated Mycobacterium genavense infection resulting from neutralizing anti-interferon-γ autoantibodies in the patient. We identified M. genavense targeting the hsp65 gene in an aspiration specimen of the lymph node. Adult-onset immunodeficiency caused by neutralizing anti-interferon-γ autoantibodies, in addition to HIV infection, can lead to disseminated nontuberculous mycobacterial infection.

Fatal Fulminant Hepatitis E in a Diabetic Patient on Metformin.

Project description:Hepatitis E is mostly autochthonous in Western developed countries, eating pig-derived products being the most frequently documented source. Hepatitis E virus (HEV) infection is usually asymptomatic or self-limiting, but it can cause acute liver failure. HEV serological testing was performed using EUROIMMUN immunoenzymatic assays. HEV RNA in the serum was determined using an in-house real-time reverse transcriptase PCR procedure. The HEV genotype was determined through phylogenetic analysis after Sanger sequencing was performed using an in-house procedure. The case patient, an immunocompetent patient in his 60s with type 2 diabetes and no documented chronic liver disease, was hospitalized in February 2021 in an intensive care unit due to an initially unexplained coma. He presented metformin overdose and fulminant hepatitis E (HEV RNA in the serum was 4,140,000 copies/mL) that evolved toward death. The HEV genotype was 3f. We identified eight previous hepatitis E in diabetic patients, but with no metformin excessive plasma concentration, in the literature. Three patients were liver transplant recipients and three died. HEV infection can be severe and life-threatening in diabetic patients, which warrants HEV testing in this special population in the case of an altered general condition and/or liver cytolysis.

Fatal disseminated infection due to <i>Sarocladium kiliense</i> in a diabetic patient with COVID-19.

Project description:Sarocladium kiliense is a soil saprophytic mold with worldwide distribution, which can infect humans and other mammals, sporadically. The clinical manifestations include mycetoma, onychomycosis, keratomycosis, pneumonia, and arthritis. Here, we present a disseminated infection due to S. kiliense in a diabetic patient infected to coronavirus disease 2019 (COVID-19) from Isfahan, Iran.

Adult-Onset Fatal Neurohepatopathy in a Woman Caused by MPV17 Mutation.

Project description:Hepatocerebral mitochondrial DNA depletion syndromes are classically considered diseases of early childhood, typically affecting the liver, peripheral, and central nervous systems with a rapidly progressive course. Evidence is emerging that initial symptom onset can extend into adulthood, though few such cases have been reported. We describe a 25-year-old woman who presented initially with secondary amenorrhea, followed by a megaloblastic anemia, lactic acidosis, leukoencephalopathy, progressive peripheral neuropathy, and liver cirrhosis. An apparently homozygous P98L mutation was identified in MPV17, a gene associated with a lethal infantile neurohepatopathy. Homozygosity for the same allele was recently reported in a man with a similar hepatic and neurologic phenotype. This is the first clinical report of an adult female with this disorder, and the first to describe amenorrhea and megaloblastic anemia as likely associated symptoms.
