Sarcoidosis, a multisystem disorder of unknown etiology that involves multiple organs, is rare in children. The true incidence and prevalence of childhood sarcoidosis is unknown. As in adults, many children with sarcoidosis may be asymptomatic; the disease may remain undiagnosed. A complete and systematic evaluation of the patient is essential for the sarcoidosis diagnosis in children. Here, we describe a case of 12-year-old female who presented with 2 years history of uveitis and hepatosplenomegaly. A chest computerized tomography revealed scattered peripheral pulmonary nodules and bilateral hiliar lymphadenopathy. Bone marrow aspiration and liver biopsy were not diagnostic. A lung biopsy showed non-necrotizing epithelioid cell granulomas. She was diagnosed with sarcoidosis according to demonstration of granulomatous inflammation and the exclusion of confusable entitiesLa sarcoidosis, un trastorno multiorgánico de etiología desconocida que afecta varios órganos, es poco frecuente en los niños. Se desconocen la incidencia y la prevalencia reales de la sarcoidosis infantil. Al igual que en los adultos, muchos niños con sarcoidosis tal vez no presentan síntomas y la enfermedad cursa sin diagnosticarse. Es fundamental realizar una evaluación completa y sistemática del paciente para establecer el diagnóstico de sarcoidosis en los niños. Se describe el caso de una niña de 12 años con uveítis y hepatoesplenomegalia de dos años de evolución. Mediante una tomografía computarizada del tórax, se hallaron nódulos pulmonares periféricos dispersos y linfadenopatía hiliar bilateral. La aspiración de médula ósea y la biopsia de hígado no fueron diagnósticas. La biopsia de pulmón mostró granulomas de células epitelioides no necrosantes. A la paciente se le diagnosticó sarcoidosis en virtud del hallazgo de inflamación granulomatosa y de la exclusión de entidades confusoras.

Hyperimmunoglobulinemia is documented in patients with Gaucher disease of all ages. We investigated the frequency of hyperimmunoglobulinemia in 12 pediatric patients with type I and III Gaucher disease and the effects of enzyme replacement therapy on these abnormalities. The incidence of hyperimmunoglobulinemia was 77%, 66%, and 60% at the diagnosis, before and after ERT, respectively. Immunoglobulin G abnormalities were the most commonly seen isotype abnormality. After enzyme replacement therapy normalization of IgA and IgM levels were recorded but decline in IgG levels was less likely to occur. This study indicated the higher frequency of hyperimmunoglobulinemia in pediatric Gaucher patients.

TTV DNA has been reported in patients with a broad spectrum of hepatic disorders as well as in healthy people.To clarify the role of TTV in children with liver disease and in healthy children.Degenerate primers designed to amplify a target sequence from the ORF 1 region of TTV genome were used for nested PCR, to detect TTV DNA in sera.TTV was detected in 3 of 18 children with chronic hepatitis B (16.7%), 2 of 17 hepatitis B carriers (11.8%), 2 of 17 children with cryptogenic chronic liver disease (11.8%), and 1 of 40 (2.5%) children without liver disease. The infection rate was similar among the various study groups and in the various age groups. There was no difference between TTV positive and negative children in respect to gender, history of surgery, parenteral treatment, transfusion of blood and blood products, presence of hepatomegaly, splenomegaly, jaundice, and transaminase values.TTV does not seem to have an etiologic role in cryptogenic liver disease in children and does not seem to influence the clinical course of liver disease.
