[Emergence of a new pathogen: Cyclospora cayetanensis in patients infected with human immunodeficiency virus]. / Emergencia de un nuevo patógeno: Cyclospora cayetanensis en pacientes infectados por el virus de inmunodeficiencia humana.

The emergence of a new pathogen Cyclospora cayetanensis as a cause of clinical disease in immunosuppressed hosts is related with prolonged, severe and highly recurrent diarrheas. This paper reports two Cuban cases of cyclosporiasis associated with infection from human immunodeficiency virus in which non sporulated oocysts of Cyclospora cayetanensis were detected in feces by modified Zielhl Neelsen's technique. The most significant clinical symptoms were chronic diarrheas and loss of body weight, with CD4 levels below 200 cells per mm3. The occurrence of severe digestive symptoms in patients with Cyclospora cayetanensi and important immune compromise backed up the concept that this pathogen may act as a new opportunistic pathogen in patients with HIV.

[HIV infection and isosporiasis. Presentation of a case]. / Infección por VIH e isosporiasis. Presentación de un caso.

A HIV seropositive patient with chronic diarrheic syndrome, in which oocysts of Isospora belli were detected in feces by the modified technique of Ziehl-Neelsen was studied. Other coproparasitological techniques were applied and cultures were applied made with negative results. Any other infectious origin was excluded from the picture. The patient was treated with 2 tablets of Co-trimoxazole (trimethoprin 80 mg, sulphamethoxazole 400 mg) every 6 hours for ten days, with referral of the symptoms.

[Infection by Schistosoma intercalatum and probable hybridization with Schistosoma haematobium in East Africa. Report of a case]. / Infección por Schistosoma intercalatum y probable hibridización con Schistosoma haematobium en el este de Africa. Reporte de un caso.

It is reported the infection due to Schistosoma intercalatum and the probable hybridization with Schistosoma haematobium in a patient from the eastern region of Africa, where it has not been demonstrated before. The main clinical manifestations were abdominal pain and diarrhea with blood. The diagnosis was possible thanks to the finding in the microscopic examination of the characteristic eggs of Schistosoma intercalatum in faeces and urine by the modified technique of Ziehl-Neelsen.

[The minimum dosage of praziquantel in the treatment of Taenia saginata, 1986-1993]. / Dosis mínima de praziquantel en el tratamiento de Taenia saginata, 1986-1993.

Praziquantel was used in a therapeutic trial in 50 patients presenting with Taenia saginata in a dose of 5 mg/body weight as a single dose. The most frequent symptoms were: abdominal pain (72%), nervousness (42%), and body weight loss (32%). Tolerance to the drug was excellent. In 100% of patients the elimination of proglottids and/or strobilus of Taenia saginata.
