[Haemophilus influenzae pulmonary infection in patients infected with the human immunodeficiency virus]. / Infección pulmonar por Haemophilus influenzae en pacientes infectados por el virus de la inmunodeficiencia humana.

BACKGROUND: Haemophilus influenzae has frequently been identified as the etiologic agent in pneumonias of patients with the human immunodeficiency virus (HIV) infection. The experience of the authors is reviewed and the significance of isolating this microorganism in respiratory samples commented upon. METHODS: The clinical, radiological and microbiological data of patients with HIV infection in whom H. influenzae was identified in blood, lung tissue, or samples of the lower respiratory tract obtained by fibrobronchoscopy were retrospectively evaluated. RESULTS: Twenty cases were diagnosed with 75% presenting bilateral lung infiltration. In 70% the isolation sample was that of bronchoalveolar lavage. In 40% of the total another microorganism was identified in coinfection with H. influenzae, of which Mycobacterium tuberculosis was the most frequent. Thirty-five percent of the cases presented antecedents of one or several previous pulmonary infections. H. influenzae infection was not observed with either concomitant or previous infections in 20% of the patients. CONCLUSIONS: A high frequency of pneumonias by Haemophilus influenzae with bilateral radiologic presentation have been found. H. influenzae is frequently demonstrated as in coinfection with other agents. The role that this microorganism has in pulmonary infection of patients with HIV infection is not clearly defined.

[Multifocal tubercular osteitis in a female patient infected with the human immunodeficiency virus]. / Osteítis tuberculosa multifocal en una paciente infectada por el virus de la inmunodeficiencia humana.

We discuss the case of a 22-year-old female, carrying of antibodies to against human immunodeficiency virus (HIV), who developed several tumors on different bone localizations, which corresponded to plurifocal bone tuberculosis. We reviewed multifocal bone tuberculosis reports in the literature. The exceptionally of this case in underlined and the relationship between this atypical clinical presentation and immunodeficiency in discussed.

[Abdominal tuberculosis in patients with acquired immunodeficiency syndrome]. / Tuberculosis abdominal en los pacientes con síndrome de inmunodeficiencia adquirida.

BACKGROUND: In individuals with HIV infection, extrapulmonary forms of tuberculosis are considered as opportunistic infections and are included in the diagnosis of AIDS. They often have atypical clinical features. Abdominal participation is uncommon and its diagnosis may be difficult. METHODS: The clinical, radiological and pathological features of patients with a diagnosis of AIDS with abdominal tuberculosis in a series of 254 AIDS cases in a general hospital from 1984 to October 1990 were reviewed. RESULTS: Tuberculosis developed in 104 (41%) of AIDS patients. In 25 (24%) the disease was exclusively pleuropulmonary and in 79 (76%) extrapulmonary tuberculosis was present, either alone or in association. Extrapulmonary tuberculosis was the first opportunistic infection in 66 AIDS cases (26%). The abdominal participation was demonstrated in 19 patients, with the following localizations: lymph nodes (9), liver (8), spleen (5), ileum (1) and peritoneum (1). Four patients with splenic tuberculosis also had multifocal nodular lesions. CONCLUSIONS: Abdominal participation was found in 19 of the 104 AIDS patients with tuberculosis (18%). Lymph node involvement was the most common type. Hepatosplenic tuberculosis had a miliary form or showed multifocal images in echography or computed tomography.
