The first AIDS patient was a homosexual male who contacted HIV infection in 1982 in Tanzania. In December 1985 the first sign of Kaposi's sarcoma was noted in this patient. HIV infection was diagnosed in him only in February 1987. He was treated with AZT, reaferon, immunoglobulin and underwent electronic therapy. His state of health was stable till February 1991. Then he got severe bacterial pneumonia, candidosis. Pancytopenia progressed. The dose of AZT (0.8 g daily) was increased and intensive antibiotic therapy and the course of diflucan were prescribed. In spite of this treatment the number of CD4 lymphocytes catastrophically decreased (CD4 = 0.01 x 10(9)/l) and the patient died. Thus, more than 63 months passed from the date of the appearance of the first symptoms of AIDS in the patient to his death.

Lymphoid interstitial pneumonitis (LIP) is a rare complication of AIDS in adults. Patients with AIDS and LIP are at high risk for bacterial pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. We have described an HIV-positive patient with LIP complicated by recurrent pneumonia due to Streptococcus pneumoniae; recurrence was apparently prevented by maintenance penicillin therapy.

The purpose of this study was to determine the prevalence of fever of unknown origin (FUO) in a cohort of HIV positive patients and to describe their evolution and the final diagnosis. The clinical records of 412 patients followed from January 1987 to December 1990 at our HIV outpatient clinic were reviewed: in 151 patients 255 episodes of fever had been observed of which 22 (in 21 patients) met the criteria for FUO. 19 patients (90%) presented with a CDC/WHO stage IV HIV infection and the mean CD4+ lymphocyte count was 0.160 G/l. The etiology was ultimately determined in 13/22 episodes (3 Pneumocystis carinii pneumonia, 3 invasive infections due to atypical mycobacteria, 2 bacterial pneumonia, 1 Cytomegalovirus colitis, 1 Isospora belli enteritis, 1 visceral leishmania, 1 candida septicemia and 1 lymphoma). In 6/22 episodes, the fever subsided after zidovudine was started and was therefore attributed to HIV itself. In 3/22 episodes no etiology was found. In conclusion, this series shows that FUO is usually seen in advanced HIV infection and that it often represents an early sign of opportunistic infection. This observation underlines the importance of follow-up, since it finally served to detect the etiology of FUO in 86% of cases. Trial treatment with zidovudine can be useful where no pathology has been discovered despite 3 weeks' follow-up and appropriate investigations.

An increased frequency of bacterial pneumonia occurs in HIV-infected individuals: however the development of bronchiectasis is not well recognized. We describe seven patients with HIV infection who developed chronic symptomatic lung disease, six with troublesome recurrent infective exacerbations. Bronchiectasis was demonstrated by computed tomography in five patients, and bronchial wall thickening was shown in a further two patients. The characteristics of the patients are described, and possible aetiological factors are discussed. As measures become available which prolong the later stages of HIV disease, bronchiectasis may become an increasing problem in this patient population. Early recognition and appropriate management may significantly alter morbidity in advanced HIV disease.

Purulent bronchitis was identified in 19 of 422 patients undergoing fiberoptic bronchoscopy during a 32-month period because of suspicion of an opportunistic lung infection complicating acquired immunodeficiency syndrome or human immunodeficiency virus infection. Five patients had Pneumocystis carinii pneumonia, but other opportunistic lung infections were excluded in the remaining 14 patients. Characteristics of these 14 patients included fever (greater than 38.3 degrees C), cough, and dyspnea in 14 of 14 patients; purulence of expectorated sputum (11/14); and widened alveolar-arterial oxygen gradient (13/14). Rapid (2 +/- 1.4 days) clinical response (defervescence and resolution of pulmonary symptoms) occurred with antibiotic therapy in 10 of 14 patients. In three patients, there was no improvement, and adult respiratory distress syndrome developed. Bacterial isolates from bronchoalveolar lavage included Streptococcus viridans (n = 12), Haemophilus influenzae (n = 7), Staphylococcus aureus (n = 3). Roentgenographic features of bronchiectasis were present in seven patients. Differential cell counts revealed greater than 50% neutrophils in the bronchial washings of all patients with purulent bronchitis. Neutrophil percentages in bronchoalveolar lavage were as follows: patient with purulent bronchitis without P carinii pneumonia (n = 14), 54.53% +/- 29.18%; patients with purulent bronchitis and concomitant P carinii pneumonia (n = 5), 62% +/- 31.9%. In a control group of 17 patients with P carinii pneumonia who did not have purulent bronchitis, the neutrophil percentage was 6.8% +/- 6.17% (p = less than 0.00001, t-test). Purulent bronchitis appears to be a distinct, treatable entity in patients with HIV infection and may accompany bacterial pneumonia, bronchiectasis, and P carinii pneumonia.

Evidence of occult alveolar haemorrhage was sought by Perls's staining of bronchoalveolar lavage fluid to detect haemosiderin laden macrophages in 63 human immunodeficiency virus positive (HIV-1) men who underwent bronchoscopy. Twenty three patients had bronchopulmonary Kaposi's sarcoma; occult alveolar haemorrhage was present in 16 of these (including two in whom no tracheobronchial lesions were evident at bronchoscopy, but in whom the diagnosis was confirmed at necropsy). Forty patients had other diagnoses including Pneumocystis carinii pneumonia and bacterial pneumonia; 18 had occult haemorrhage. Occult alveolar haemorrhage seems to be a non-specific finding in HIV-1 positive men undergoing bronchoscopy.

In a prospective study the efficacy of fiberoptic bronchoscopy was evaluated in the diagnosis of infections with opportunistic pathogens, Kaposi's sarcoma and nonspecific interstitial pneumonitis in 171 episodes of pneumonitis in 151 HIV-infected patients. Samples were collected by suction through the inner aspiration channel of the bronchoscope (n = 164), telescoping plugged catheter (n = 117) and transbronchial lung biopsy (n = 82). A high incidence of infections with pyogenic bacteria (12%), Legionella spp. (5 %) and Mycobacterium tuberculosis were diagnosed (9%). Bronchoalveolar lavage demonstrated a high diagnostic rate in bacterial pneumonia (significance level greater than 10(5) cfu/ml) and a low degree (10%) of contamination (less than 1% squamous epithelial cells). Bronchoalveolar lavage was more effective than the telescoping plugged catheter in yielding a significant number of colonies in patients with bacterial pneumonia previously treated with antibiotics. Nondiagnosed pneumonitis was more frequent in intravenous drug abusers than in homosexual men (p less than 0.001).

Ninety consecutive first-time fiberoptic bronchoscopies (FB) were performed on HIV-infected patients with pulmonary symptoms and radiographic evidence of active pneumonitis. Microbiological data were analysed for acute and long-term prognostic significance. 56/90 (63%) patients had one type of microbiological agent recovered from FB, 22/90 (24%) patients had more types recovered, and 12/90 (13%) patients had no types recovered. Nine patients (10%) died during the acute episode of pneumonia. A prognostic factor of a fatal outcome of the acute episode of pneumonia was concurrent multiple pulmonary infections (p = 0.002), mainly ascribed to patients with Pneumocystis carinii pneumonia (PCP) and concomitant bacterial pneumonia (p = 0.003). Specific microbiological findings at FB did not influence long-term survival of patients, and, when omitting patients who died during the acute episode of pneumonia (n = 9), no difference in survival was observed between patients with a) no agent, b) one type of agent or c) more types of agents recovered from FB. Only non-pulmonary parameters such as CD4-count, haemoglobin and age were found to be prognostic parameters. Thus, increased attention should be paid to co-pathogens presenting in HIV-infected patients with pulmonary infection and appropriate therapy instituted.

A 40-year-old, HIV-infected female patient received antibiotic treatment for a urinary tract infection. After the initial success of therapy and a symptom-free period, she developed pneumonia with septic shock and adult respiratory distress syndrome (ARDS). In spite of intensive care and respirator therapy with positive end-expiratory pressure (PEEP), she died of infectious toxic shock. Autopsy findings showed relapsing, gram-negative, bacterial pneumonia (morphologically compatible with Klebsiella pneumonia) and secondary, invasive aspergillosis. The pathogenesis and epidemiology of these unusual complications of AIDS are discussed.

Pneumonia caused by common pyogenic bacteria occurs frequently in HIV-infected patients. Its clinical presentation has been described as being similar to that seen in non-immunosuppressed hosts but clearly different to that of opportunistic pneumonias. An atypical presentation has rarely been seen. In a 10-month period, we saw 12 HIV-infected patients who presented with Haemophilus influenzae pneumonia which was clinically and radiologically indistinguishable from Pneumocystis carinii pneumonia. Ten of the patients were intravenous drug users and were in different stages of HIV disease. The clinical picture was characterized by a prolonged course (median 4 weeks), non-productive cough, dyspnoea, and absence of findings usually present in bacterial pneumonia. Laboratory data frequently showed absence of leukocytosis, increased lactate dehydrogenase levels, hypoxaemia, and decreased CD4+ cell counts. All presented with interstitial or mixed bilateral infiltrates. Resistance to ampicillin and trimethoprim-sulphamethoxazole were each found in seven cases. Eleven patients were cured with antibiotic therapy, although five relapsed. H. influenzae pneumonia should be considered in HIV-infected patients who present with pulmonary symptoms and bilateral infiltrates of subacute or chronic onset. Clinical resolution of pneumonia is the usual outcome, but recurrences of infection are frequent.
