Adult-onset Still's disease is characterized by high spiking fever, evanescent maculopapular rash and arthritis. Several recent reports have associated its development with a variety of infectious agents. We describe the case of a 25-year old woman presenting high fever, maculopapular rash and seronegative polyarthritis associated with lymphoadenopathy, splenomegaly and neutrophil leucocytosis together with acute acquired toxoplasmosis. Other causes of systemic illness were excluded by appropriate laboratory, radiological and histological investigations. Clinical, radiological and laboratory findings as well as possible etiopathogenetic correlations among both pathological conditions are discussed. Toxoplasma gondii should be considered as a further possible triggering agent associated with the development of adult-onset Still's disease.

A 2 year old girl presented with fever, malaise, a maculopapular rash and lymphadenopathy followed by the onset of haemolytic anaemia and massive splenomegaly. Serology was consistent with acquired toxoplasmosis. A 6 week course of pyrimethamine resulted in a rise in the haemoglobin and reduction of the splenomegaly. During the subsequent 10 years, pyrimethamine treatment of three similar acute episodes resulted in similar clinical responses. There was no spontaneous improvement in the haemolytic anaemia or splenomegaly when pyrimethamine was initially withheld for 6, 1, and 1.5 months respectively during three of these episodes. Investigations did not reveal an immunodeficiency state. This case suggests the possibility of a previously unreported causal association between acquired toxoplasmosis and haemolytic anaemia in a child.

Most cases of acute acquired toxoplasmosis (AAT) are oligosymptomatic and self-limited. Therefore, these infections rarely indicate treatment. Prospective studies of AAT patients are rare in the medical literature. The frequency of systemic manifestations has not been sufficiently studied. In order to search for risks factors for systemic and ocular involvement, 37 patients were submitted to a diagnostic investigative protocol. The most frequent findings were lymph node enlargement (94.6%), asthenia (86.5%), headache (70.3%), fever (67.6%) and weight loss (62.2%). Hepatomegaly and/or splenomegaly were present in 21.6% of cases (8/37). Liver transaminases were elevated in 11 patients (29.7%) and lactic dehydrogenase in 17 patients (45.9%). Anaemia was found in four patients (10.8%), leucopoenia in six patients (16.2%), lymphocytosis in 14 patients (37.8%) and thrombocytopenia in one patient (2.7%). Fundoscopic examination revealed retinochoroiditis in four patients (10.8%). No statistical association was found between any one morbidity and retinochoroiditis. Nevertheless, a significant association was found between the presence of more than eight morbidity features at evaluation and long-lasting disease. An ideal diagnostic protocol for AAT would include evidence of systemic involvement. Such a protocol could be used when planning treatment.

Disseminated toxoplasmosis presenting as a prolonged febrile illness is rare in immunocompetent individuals. We report a probable case of acquired toxoplasmosis in an immunocompetent woman who presented with fever of 6 months duration with lymphadenopathy and splenomegaly. The diagnosis was confirmed by serology and the presence of Toxoplasma gondii tachyzoites on bone marrow aspirate. The patient was successfully treated with pyrimethamine plus clindamycin.
