- Hand, Foot, and Mouth Syndrome in an Immunocompetent Adult: a Case ReportPublication . Flor de Lima, B; Silva, J; Rodrigues, AC; Grilo, A; Riso, N; Vaz Riscado, MBACKGROUND: Hand, foot, and mouth syndrome (HFMS) is a common acute illness. It is characterized by mild clinical symptoms including fever, blisters, and sores in the mouth and on the palms and soles following a 3- to 7-day incubation period. This syndrome is rarely seen in adults. CASE PRESENTATION: A 35-year-old male Caucasian patient had a history of multiple episodes of acute pharyngitis, hypertension, hypercholesterolemia, and occasional abdominal pain. He presented with polyarthralgia in the knees and hands and odynophagia, followed by fever, oral mucosal aphthous lesions, and vesicles on the palms and soles. Three weeks after presentation, he was admitted to the emergency room with acute myocarditis. The in-hospital evaluation revealed positive serology for coxsackie A9 (1:160), positive anti-transglutaminase and anti-gliadin antibodies, normal immunoglobulins, and human immunodeficiency virus negativity. CONCLUSION: We herein describe a case of HFMS that was associated with coxsackie A9 infection complicated by acute myocarditis. Although an association between celiac disease and HFMS has not been described, this patient's immunologic disruption could have favored the development of infection and ultimately HFMS.
- Severe Acute Hepatitis E in a Woman with an Autoimmune BackgroundPublication . Nascimento, M; Almeida-Santos, M; Fernandes, M; Maltez, F; Lino, S; Curran, M; Mesquita, JHepatitis E virus genotype 3 infections are normally asymptomatic in immunocompetent individuals. Symptomatic cases of acute icteric hepatitis E are seldom observed among women, younger men and children but are particularly seen in middle-aged/elderly men. We report a case of severe acute hepatitis E caused by genotype 3 in an immunocompetent 40-year-old woman that required prolonged hospitalization. Her medical history included an autoimmune background, namely atrophic gastritis and Graves' disease. She presented an extensive hepatic necrosis as revealed by the high levels of aminotransferases (ALT 4893 U/L; AST 3138 U/L). She showed also a coagulation disorder (prothrombin time; INR = 1.33). Serological markers for hepatitis viruses A, B and C were negative but serum was positive for hepatitis E virus RNA. Sequencing and phylogenetic analysis revealed that the hepatitis E virus strain belonged to subgenotype 3a. This is suggestive of an association between the severe acute hepatitis E virus genotype 3 infection and the autoimmune background.
