[Coinfection of Mycobacterium malmoense and Mycobacterium tuberculosis in a patient with acquired inmune deficiency syndrome].

A case is presented of coinfection with Mycobacterium malmoense and Mycobacterium tuberculosis in a Cuban patient with AIDS which produced respiratory and liver disease respectively. Cultures done from sputum samples showed the presence of a non-pigmented, slow growing mycobacterial strain belonging to Runyon group III and identified as Mycobacterium malmoense. From cultures of liver tissue removed laparoscopically, a strain was isolated and subsequently identified as Mycobacterium tuberculosis.

[Behaviour of HIV/AIDS-related lymphoma in Pedro Kouri Institute. 2004-2005].

A prospective and descriptive study of 20 patients infected with HIV and admitted to "Pedro Kouri" Institute of Tropical Disease after a diagnosis of lymphoma was conducted. They were all evaluated at the onset of diagnosis by a thorough medical record exam and supportive studies such as complete blood count, globular sedimentation speed, CD4+ count, lactic acid dehydrogenase, HIV viral load, cytology and biopsy. Of this number, 85% presented with CD4+ count under 350 cell/mm3 at the time of diagnosis; however, only 55% showed viral loads exceeding 50,000 copies/mL.

[Disseminated mycobacteriosis associated with Mycobacterium avium-intracellular (MAI) complex in HIV infected patients].

Different types of samples from a 27-year-old female patient who was diagnosed AIDS after presenting an acute respiratory picture caused by Pneumocistis carinii, in 1997, were studied. From that moment on, the patient continued having respiratory pictures repeatedly, until she was admitted at "Pedro Kouri" Institute of Tropical Medicine with a chronic diarrheical picture, significant loss of weight and extreme anorexia, together with a constant wet cough, fever, etc. The necessary complementary tests were made and a hyperergic Mantoux and very low levels of CD4 cells (under 200 cells/m3) outstood.
