To assess the health values of patients infected with human immunodeficiency virus (HIV) and examine the relationships between their health values and health status at two points in time, the authors sought to determine whether patients' physical and mental health statuses were good predictors of how they valued their current state of health. One hundred thirty-nine patients with various stages of HIV infection were interviewed in a prospective cohort study based in a primary care practice of a community-based teaching hospital. Patients were interviewed twice at 6-month intervals using three health value measures--the time trade off, rating scale, and Quality of Well-being Scale--and three health status measures: the 18-item Mental Health Inventory, the Dyspnea-Fatigue Index, and the Medical Outcomes Study SF-36 Health Survey. The health status of HIV-infected patients was compromised and, with the exception of mental health, generally was worse among patients with more advanced HIV-infection. Rating scale and Quality of Well-being Scale scores were related inversely to disease stage, but time-trade off scores generally were higher regardless of disease stage. Health value measures showed moderate relationships with measures of physical functioning (r = 0.34-0.68) but only a fair relationship with mental health (r = 0.00-0.48). The health status of HIV-infected patients who remained asymptomatic or remained symptomatic but without developing acquired immunodeficiency syndrome (AIDS) changed little over 6 months, whereas the health status of patients with AIDS and of patients manifesting progression of HIV-infection deteriorated over time. In contrast, health values, particularly time-tradeoff scores, remained stable even in the face of changes in health status and disease progression. With the exception of mental health, the impact of HIV infection on health status tends to parallel the clinical stage of disease. Health values of HIV-infected patients, however, generally are high and correlate better with physical functioning than with mental health.

A 33-yr-old homosexual man with acquired immune deficiency syndrome (AIDS) and Mycobacterium avium intracellulare (MAI) infection presented with fever, sweats, lethargy and dyspnea. A chest radiograph showed cardiomegaly and an echocardiograph revealed a large pericardial effusion. After pericardial aspiration, which confirmed T cell non-Hodgkin's lymphoma, he remained dyspneic. Gallium-67 imaging was performed to determine whether the patient's residual dyspnea was related to pulmonary MAI infection or lymphomatous infiltration of the heart. Planar 67Ga scintigraphy revealed intense tracer uptake in two areas within the mediastinum and surrounding the entire heart shadow but no evidence of pulmonary MAI infection. SPECT 67Ga scintigraphy precisely localized the two mediastinal abnormalities and demonstrated the tracer uptake around the heart to be pericardial rather than myocardial. Gallium-67 scintigraphy suggested that pericardial lymphoma was the likely basis of the patient's dyspnea.

This report describes a 28-year-old, HIV-infected man presenting with subacute onset of pyrexia, cough, dyspnoea and pleuritic pain. Chest radiograph showed bilateral multiple cavitary lesions. The diagnosis of salmonellosis was secured by isolation of salmonella typhimurium in blood, as well as in sputum. Therapy with sequential ceftriaxone/ciprofloxacin led to satisfactory improvement symptomatically and radiologically. The present report serves to heighten the awareness of AIDS-associated salmonella bacteremia and lung abscesses.

We identified 31 patients with human immunodeficiency virus (HIV) infection and lung abscess. All patients had advanced HIV disease, and the mean CD4 cell count was 17/mm3 (range, 2-50/mm3). Twenty-two patients (71%) had previous opportunistic infections, and 24 (77%) had previous pulmonary infections. Symptoms at the time of presentation included fever (90% of patients), cough (87%), dyspnea (35%), pleuritic chest pain (26%), and hemoptysis (10%). The microbiological etiology was established for 28 patients, and the pathogens recovered were bacteria (65%), Pneumocystis carinii (6%), fungi (3%), and mixed microorganisms (16%). The pathogens included Pseudomonas aeruginosa (11), Streptococcus pneumoniae (6), P. carinii (5), Klebsiella pneumoniae (5), Staphylococcus aureus (4), Aspergillus species (3), viridans streptococcus (2), Haemophilus influenzae (1), Streptococcus milleri (1), Proteus mirabilis (1), and Cryptococcus neoformans (1). Mycobacterium tuberculosis was not isolated; two patients for whom a microbiological etiology was not established responded to antituberculous therapy. Patients were treated for 2-12 weeks; 25% of the patients received > 4 weeks of therapy. The outcome was poor: 36% of the patients had recurrences, and 19% died. In patients with AIDS, lung abscess is associated with advanced HIV infection, is due to a broad spectrum of pathogens, responds poorly to antibiotics, and has a poor prognosis.

A 22 year-old Thai male was admitted to our hospital because of chest pain and dyspnea. In 1989, he met with a traffic accident and was injured his head and the arm, and was given a blood transfusion in Thai. Laboratory examinations on admission revealed that serolopositivity for HIV, and CD4+T lymphocyte count was 17/microliter. Chest X-ray on admission showed bilateral diffuse nodular shadow, and he was diagnosed as miliary tuberculosis with AIDS. On the chest X-ray, in the right upper middle lung fields, the shadow was rough and partly influent. In the left lung, the nodular shadow were smaller and distributed evenly. As there was a difference in the distribution of nodular shadows between the left and right lung, the chest X-ray findings of this case was atypical of miliary tuberculosis.

Five case of intestinal cryptosporidiosis with pulmonary involvement in patients with AIDS are reported. The diagnosis was based on the recognition of acid-fast oocysts in sputum or aspirated bronchial material and stool specimens. Coughing and excess secretions were present in all cases. Four patients had other associated pulmonary pathogens: two Mycobacterium tuberculosis, one Mycobacterium fortuitum and one Cytomegalovirus + Pneumocystis carinii; all of them had a previous (three cases) or simultaneous (one case) diagnosis of intestinal cryptosporidiosis, presenting with diarrhoea and vomiting. In the fifth patient Cryptosporidium was the only pulmonary pathogen found in a bronchial aspirate, and the onset of diarrhoea was 1 month after respiratory detection. Fifty-seven cases of respiratory cryptosporidiosis have been reported since 1980. In 17 of them, no other pathogen was found. Diarrhoea was present in 77% of the patients, cough in 77%, dyspnea in 58%, expectoration in 54%, fever in 45%, thoracic pain in 33%.

We reviewed all cases of pulmonary toxoplasmosis (PT) that were documented by detection of Toxoplasma gondii in bronchoalveolar lavage fluid specimens during a French nationwide review of extracerebral toxoplasmosis in patients infected with human immunodeficiency virus (HIV). Only 64 cases of proven PT were recorded during the 33-month survey. The patients were similar to other patients with AIDS in terms of age, sex, and risk factors for HIV infection. PT occurred mainly in patients with advanced immunodeficiency (mean [+/- SD] CD4+ lymphocyte count, 40 +/- 75/mm3). Clinical features of PT usually include fever, cough and dyspnea; the associated radiological findings were mainly diffuse interstitial infiltrates. Serological data were uninformative. The treatment for PT was the same as that for cerebral toxoplasmosis. A clinical response was observed for 47% of patients, 23% of whom relapsed. Twenty-four patients (37%) died of toxoplasmosis, and 17 (27%) died of other causes. The median survival time was 150 days. We conclude that PT is an infrequent but severe infection in HIV-patients in France.

In May 1995, a 52-year-old man complaining of fever and dyspnea was admitted to a hospital. Based on clinical and radiographic findings, hypersensitivity pneumonitis was suspected. Steroid pulse therapy was unsuccessful, and he was then transferred to our hospital. A chest X-ray film showed bilateral ground-glass shadows and a high-resolution CT scan showed cystic air spaces. The number of CD4-positive lymphocytes in peripheral blood was very low. A test for anti-human immunodeficiency virus antibody was positive and Pneumocystic carinii was found in bronchoalveolar lavage fluid. The acquired immunodeficiency syndrome and Pneumocystis carinii pneumonia were diagnosed. In this patient, the level of serum KL-6, a new marker of interstitial pneumonitis, was very high, and KL-6 was expressed on type II pneumocytes. The level of serum KL-6 may be useful as a marker of the activity of Pneumocystis carinii pneumonia.

This randomized, open-labeled, multicenter study was designed to assess safety and pharmacokinetics of dronabinol (Marinol) tablets and megestrol acetate (Megace) micronized tablets, alone and in combination, for treatment of HIV wasting syndrome. Weight and quality of life data were also collected. Fifty-two patients (mean CD4+ count, 59 cells/microliter) were randomized to one of four treatment arms: dronabinol 2.5 mg twice/day (D); megestrol acetate 750 mg/day (M750); megestrol acetate 750 mg/day+dronabinol 2.5 mg twice/day (M750+D); or megestrol acetate 250 mg/day+dronabinol 2.5 mg twice/day (M250+D). After therapy initiation, 47 patients returned for at least one visit, and 39 completed the planned 12 weeks of study visits. Occurrence of adverse events, drug discontinuation, new AIDS-defining conditions, or CD4+ T lymphocyte changes were not statistically significantly different among arms. Serious adverse events assessed as related to dronabinol included CNS events (e.g., confusion, anxiety, emotional lability, euphoria, hallucinations) and those assessed as related to megestrol acetate included dyspnea, liver enzyme changes, and hyperglycemia. The mean weight change +/- SE over 12 weeks was as follows: D, -2.0 +/- 1.3 kg; M750, +6.5 +/- 1.1 kg; M750+D, +6.0 +/- 1.0 kg; and M250+D, -0.3 +/- 1.0 kg (difference among treatment arms, p = 0.0001). Pharmacokinetic parameters measured after 2 weeks of therapy for M750 were Cmax = 985 ng/ml and AUC = 22,487 ng x hr/ml, and for dronabinol and its active metabolite (HO-THC), respectively, were Cmax = 2.01; 4.61 ng/ml and AUC = 5.3; 23.7 ng x hr/ml. For megestrol acetate, but not dronabinol, there was a positive correlation at week 2 between both Cmax and AUC with each of the following: (1) weight change, (2) breakfast visual analog scale for hunger (VASH) score, and (3) dinner VASH score.

The records of patients in whom Pneumocystis carinii pneumonia (PCP) was diagnosed between January 1989 and December 1991 were reviewed. Thirty-two patients--all immunocompromised--were included in the study: 41% were HIV-positive and 59% HIV-negative. In 23 patients (72%) concomitant pathogens were isolated, most frequently Cytomegalovirus. Presenting symptoms included fever (97%), cough (75%) and dyspnea (63%). All HIV-infected patients had a T4-lymphocyte count below 200/mm3 (or 20%). The majority of patients (80%) treated with trimethoprim-sulfamethoxazole experienced adverse events which were usually well tolerated so that a therapy change was necessary in only 12% of patients. PCP was fatal in 34% of the patients. Respiratory failure requiring mechanical ventilation carries a poor prognosis. The ratio of non-AIDS/AIDS patients infected with PC is increasing. This increase is due to the growing contribution of patients treated with immunosuppressive agents and patients with disease-associated immunodeficiencies other than AIDS. Our study suggests that treatment of PCP is more successful with early diagnosis. In addition, as mortality rate is high in non-AIDS patients, our data suggest that the more frequent use of PCP prophylaxis in patients given immunosuppressive drugs, might reduce the incidence of PCP and PCP related mortality.
