A 19-year-old woman with a childhood history of cavitating left upper lobe
pneumonia
presented with persistent weight loss, fever, cough and roentgenographic evidence of right upper lobe
pneumonia
resistant to antibiotic therapy. An open lung biopsy led to the diagnosis of botryomycosis. Neutrophil function studies including flow cytometric evaluation of oxidative burst, bacterial killing and evaluation of neutrophil cytosolic proteins required for oxidase activation were consistent with chronic granulomatous disease. This is the first case report of primary pulmonary botryomycosis as a clinical manifestation of CGD. Other recent cases of
immunodeficiency
states associated with botryomycosis are reviewed.

During 1983-1988, hospitalizations of patients with a diagnosis of human
immunodeficiency
virus (HIV) infection increased from 1.3 to 33.7 per 100,000 persons. We used the National Hospital Discharge Survey, which is based on a representative sample of discharges from nonfederal short-stay hospitals, to describe illnesses among hospitalized patients with HIV infection. Of 222,200 such hospitalizations during 1983-1988, most occurred among persons who were 25-44 years of age (79%), white (66%), and male (90%). Among men 25-44 years of age, HIV admissions increased from 8.5 to 148.6 per 100,000 persons during 1983-1988; among black men 25-44 years of age, HIV hospitalizations increased from 43.1 to 387.4 per 100,000 persons. Among women, hospitalizations increased 3.4-fold. Frequently listed illnesses in the Centers for Disease Control (CDC) AIDS case definition were Pneumocystis carinii pneumonia (30%), candidiasis (20%), and Kaposi's sarcoma (13%). Other frequently listed illnesses included infections (39%) such as
pneumonia
, sepsis, and urinary tract infections; blood dyscrasias (30%) such as anemia, thrombocytopenia, and agranulocytosis; metabolic (17%), gastrointestinal (16%), and respiratory disorders (12%); and drug abuse (9%). These data provide a minimum estimate of HIV hospitalizations because for some patients HIV infection may not be specified on the discharge record. HIV hospitalizations are increasing markedly and are associated with a broad spectrum of severe morbidity.

This study reports on four empirical models likely to contribute to understanding the behaviors linked with human
immunodeficiency
virus (HIV) among intravenous drug users. The sample comprises 1,637 intravenous drug users recruited between May 1989 and June 1990 in San Juan, Puerto Rico. Adjusting for sociodemographics, four logistic regression models were constructed to assess the association of risk behaviors with HIV seropositivity. In model 1, the variables found to be significantly associated with HIV seropositivity were injecting four times a day, injection as the only route of consuming drugs, and years of injection. In model 2, the only risk behavior significantly associated with HIV seropositivity was injecting drugs in shooting galleries. In model 3, all sex risk variables failed to meet the adjusted level of significance. In model 4,
pneumonia
, hepatitis, and syphilis were significantly linked with HIV infection. In order to assess the individual effects of the significant variables in each one of the four models, a logistic regression analysis was performed simultaneously controlling for all of the variables. After adjustment for the Bonferroni correction, age group 25-34 years, injection as the only route of using drugs, number of years of injection, and syphilis were the only significant variables remaining.

Although AIDS was largely recognized and defined because of the increased presence of diseases that reflect deficiencies in cell-mediated immunity, susceptibility to common extracellular bacterial pathogens has also been shown to be increased. To our knowledge, adults with concurrent infection due to human
immunodeficiency
virus (HIV) and Streptococcus pneumoniae whose cases have been described to date have all had pneumococcal
pneumonia
and/or bacteremia. We describe five cases of HIV-infected patients who had unusual manifestations of pneumococcal infection, which include recurrent exudative pleural effusion, pyopneumothorax, purpura fulminans, mediastinitis with chest wall abscess, and multiple brain abscesses. Such complications of pneumococcal infection occurred more or less commonly in the preantibiotic era, but on the basis of our experience and an exhaustive literature search, these complications have been exceedingly rare in the past few decades. In four of our five patients, the unusual, complicated pneumococcal disease preceded and prompted a search for HIV infection. Because concurrent HIV infection increases the susceptibility to pneumococcal disease, other such cases are likely to be seen.

Pneumonia
by Pneumocystis carinii (NPC) presents a high incidence in the evolution of patients infected by the human
immunodeficiency
virus (HIV). Common clinical signs include fever, dry cough and dyspnea, in the presence of pulmonar interstitial affection with several degrees of hypoxemia. One hundred and sixteen patients with NPC and infection by HIV were diagnosed between December 1986 and January 1990. Criteria of persistent fever was established in 10 of them (8.7%), with normal thoracic radiography at the time of hospitalization. NPC in the adquired
immunodeficiency syndrome
(SIDA) may develop' with persistent fever, joining the large relation of entities manifesting in this way.

Antibody responses to a major purified human Pneumocystis carinii surface antigen (gp95) were determined by ELISA in human
immunodeficiency
virus (HIV)-infected patients. Serum IgG directed against gp95 was measured in 129 consecutive HIV-infected patients who underwent bronchoscopy for evaluation of pulmonary symptoms. Significantly more patients with P. carinii
pneumonia
(PCP) had detectable antibodies compared with HIV-infected patients without PCP and with HIV-negative controls (50 [66%] of 76 vs. 18 [34%] of 53 and 7 [35%] of 20, respectively; P less than .001), and the level of antibody response was higher (mean optical density ratio: 0.6 vs. 0.23 and 0.2, respectively; P less than .01). Changes in antibody response were investigated in 78 patients for whom serial serum samples taken around the time of bronchoscopy were available. Of the 47 patients with verified PCP, 20 (43%) mounted an antibody response, compared with only 1 (3%) of 31 patients without PCP (P less than .001). This patient had PCP on the basis of clinical criteria, including response to therapy. Thus, despite severe immunosuppression, a proportion of HIV-infected patients with PCP can mount a specific IgG-mediated antibody response to P. carinii.

Rhodococcus equi, a facultative intracellular bacterium, is a common cause of pulmonary infection in farm animals, especially foals. Pulmonary and disseminated infection caused by this organism is occasionally seen in humans, especially in patients whose cell-mediated immunity has been altered by glucocorticoids or cytotoxic chemotherapy. Not surprisingly, the organism may cause serious disease in human
immunodeficiency
virus (HIV)-infected humans whose T cell-dependent immune system has been profoundly suppressed. This report describes an HIV infected patient with Rhodococcus equi
pneumonia
and reviews nine additional HIV-infected patients. Treatment in humans is not standardized. Studies in foals indicate that erythromycin and rifampin together are the treatment of choice. The patient in this report responded to this treatment briefly before relapsing and dying of the infection.

The records of 18 immunocompromised patients with recent onset of pulmonary disease who had fibreoptic bronchoscopy and bronchoalveolar lavage over a two year period (1989-90) were reviewed. The underlying diseases were human
immunodeficiency
virus (HIV) infection (n = 7), organ transplantation (n = 9), and chemotherapy for malignancy (n = 2). Four patients were receiving prophylactic therapy and 12 had been started on empirical therapy for infection. Patients proceeded to bronchoscopy either because of atypical disease presentation or failure to respond to empirical therapy. Bronchoscopy with bronchoalveolar lavage was diagnostic in 13/18 (72%) patients and provided clinically useful information in 16/18 (89%). There was one diagnostic failure (6%); Pneumocystis carinii pneumonia in an HIV positive patient receiving nebulised pentamidine prophylaxis was missed. Transbronchial biopsies were not routinely performed and provided additional diagnostic information in only 1/6 (17%) patients. Overall, the commonest diagnoses were Pneumocystis carinii pneumonia (61%) and cytomegalovirus
pneumonitis
(28%). There were no complications of the procedures. In this highly selected setting of diagnostic or therapeutic uncertainty, fibreoptic bronchoscopy with bronchoalveolar lavage remains an effective and safe technique for evaluating pulmonary disease in immunocompromised patients.

This article describes the first case of Pneumocystis carinii pneumonia in a human
immunodeficiency
virus (HIV) seropositive infant in whom apnea was the earliest presenting clinical finding. Pediatricians treating infants with HIV infection need to be aware of this unusual clinical presentation of P carinii
pneumonia
to avoid a delay in diagnosis and management of this disease.

Four patients admitted with a pneumococcal
pneumonia
are described. Well-known risk factors such as
immunodeficiency
or preexisting cardiopulmonary problems were absent. They had been ill for three to five days and had not been treated with antibiotics. Three patients died; upon admission these had extensive pulmonary infiltrates (two or more lobes affected), respiratory insufficiency necessitating mechanical ventilation, and shock at or soon after admission. The prognosis of pneumococcal
pneumonia
with a fulminant course has not improved in the last few decades despite proper antibiotics and intensive care treatment. Mortality is over fifty percent. Early recognition and treatment can contribute to a better prognosis.
