To examine the impact of the AIDS epidemic on morbidity and mortality in a defined population of intravenous drug users, we analyzed overall and cause-specific death rates, AIDS incidence, and acute medical hospitalizations among patients in a long-term methadone maintenance program in New York City for the years 1984 through 1987 (midyear population for each year 828 to 891; demographic characteristics did not differ). The number of deaths while in treatment increased from 11 (13.3/1000) in 1984 to 39 (44.2/1000) in 1987. Deaths from AIDS increased from 3.6/1000 to 14.7/1000, deaths due to bacterial pneumonia/sepsis from 3.6/1000 to 13.6/1000; deaths from cirrhosis, drug overdose, trauma, and other causes remained relatively stable. AIDS incidence rose from six cases/1000 in 1984 to 20.4.1000 in 1987. Hospitalizations for AIDS, pneumonia, tuberculosis, and endocarditis/sepsis increased from 84.9/1000 in 1986 to 144.8/1000 in 1987. These data suggest that the AIDS epidemic has had a profound effect on patterns of morbidity and mortality among intravenous drug users in this methadone program population. Drug treatment programs may be important sites for targeting clinical services for drug users with AIDS, although the increasing burden of AIDS-related disease will require expansion of existing funding and treatment resources.

Between 1912 and 1980, many English language publications analyzed the correlation between clinicians' diagnoses and postmortem examinations. Surprisingly, the percentage of cases with undiagnosed principal underlying diseases or primary causes of death has not diminished during this period. The autopsy's unvarying percentage yield does not indicate a lack of progress, however, since bacterial pneumonia, hepatic cirrhosis, and common tumors were missed routinely in earlier eras but were rarely missed after 1970. Pulmonary embolism remains commonly missed, but the striking recent finding is the emergence of fungal and other systemic infections that were rarely noted in prior eras. Progress in diagnosis and treatment may allow patients to live longer and new or obscure diseases may develop that will often be missed clinically. An appropriately high autopsy rate will be required if medical progress is to continue.

This study is based on a retrospective logistic regression analysis of all human immunodeficiency virus (HIV)-infected patients with Staphylococcus aureus pneumonia (SAP) admitted to the Department of Infectious Diseases, Catholic University, Rome, Italy between January 1986 and December 1994. Nineteen patients with 24 episodes of SAP were enrolled in the study. A control group of 38 HIV-infected patients without pneumonia was included. The attack rate of SAP was 8.31/1000 HIV-related hospital admissions and the frequency, out of the total number of bacterial pneumonia observed in the study period, was 16% (24 of 154 patients). The large majority of SAP was community acquired. On the univariate analysis, intravenous drug abuse (IVDA) (P = 0.02), history of previous Pneumocystis carinii pneumonia (PCP) (P = 0.03) and cirrhosis (P = 0.03) were significant risk factors for SAP. In addition, IVDA and previous PCP were independent risk factors on multivariate analysis. All patients presented with fever associated with cough (74%), chest pain (26%) or shortness of breath (37%). Chest X-ray documented lobar pneumonia (78%), predominantly in the lower lobes, consolidation with cavitation (11%), and interstitial-nodular infiltrates (11%). Pleural effusion was present in 31% of patients. The response to therapy was favourable in 79% of patients. Recurrence occurred in 26% and death occurred in 21% of patients. Death was significantly associated with the low level (< 50 mm-3) of circulating T CD4+ cells (P = 0.03) and the recurrence of pneumonia (P = 0.03). In conclusion, the present study indicates that S. aureus is an important aetiologic agent of bacterial pneumonia in HIV-infected patients, especially if they are drug abusers with previous PCP.

This case control study assessed risk factors and prognostic indicators of 350 episodes of bacterial pneumonia in 285 HIV-infected patients. On univariate analysis, intravenous drug abuse (i.v.DA; p < .001 versus controls), regular cigarette smoking (p < .001), cirrhosis (p = .04), and history of a previous episode of pneumonia (p = .04) were risk factors for community-acquired episodes of bacterial pneumonia, whereas length of hospitalization (p = .01) was a risk factor only for nosocomial bacterial pneumonia. The small amount of circulating T CD4+ cells (<100/ mm3) was a risk factor in both groups of pneumonia (p < .05). Stepwise logistic regression analysis revealed that i.v.DA in community-acquired episodes and low levels of circulating T CD4+ cells, both in community-acquired and hospital-acquired episodes, were independent risk factors for the development of bacterial pneumonia. The case-fatality rate observed in our study was 27%. On stepwise logistic regression analysis, T CD4+ cell counts < or = 100/mm3 (p = .02), neutropenia (p = .04), PO2 arterial level < or = 70 mm Hg (p = .01), and Karnofsky score < or = 50 (p = .04) were independent indicators of mortality. According to a personally developed prognostic score, 211 episodes of pneumonia (60%) were classified as mild, 63 (18%) as moderate, and 76 (22%) as severe. Clinicians must carefully evaluate those variables that can influence the prognosis of bacterial pneumonia to make early identification of affected patients and to promptly establish the most appropriate therapeutic strategy in each case.

A 66-year old man was admitted to our hospital because of vomiting, diarrhea and progressive dyspnea. Acute respiratory distress syndrome (ARDS) due to bilateral pneumonia was diagnosed and he was also in septic shock. The patient had a history of partial hepatectomy for hepatoma, and suffered from liver cirrhosis. Emergency bronchoalveolar lavage (BAL) revealed abundant gram-positive cocci and polymorphonuclear leukocytes in the collected sample. Blood culture revealed corynebacterium. Treatment consisted of mechanical ventilation and administration of fluids, effective antibiotics, and high-dose methylprednisolone (MPS). MPS was administered from the onset of ARDS with a starting dose of 1,000 mg, which was gradually reduced to 60 mg over 8 days. Pulmonary infiltrates shown on the chest X-ray film were alleviated, and arterial blood gas data rapidly improved. The patient was successfully extubated on the 10th hospital day, and discharged on the 30th hospital day. Serial BAL and plasma levels of inflammatory cytokines decreased rapidly in parallel with the improvement of the patient's clinical condition. This is a case report of severe bacterial pneumonia that was successfully treated with effective antibiotics and high-dose MPS for several days from the onset of ARDS.

We performed limited autopsy with histological examination of tissue cores obtained percutaneously using the Tru-Cut needle and the Jamshidi trocar in 150 adult HIV-positive patients. Data were compared retrospectively with the antemortem clinical diagnosis. Eighty-one percent of the patients were male, and 78% were intravenous drug users. Specimens were obtained from the brain, liver, lung, bone marrow, and kidney of most patients. The main findings included liver cirrhosis in 22 cases (associated with HCV infection in 81%), Pneumocystis carinii pneumonia in 21, Cytomegalovirus (CMV) infection in 19, Mycobacterium avium-intracellulaire (MAI) infection in 17, bacterial pneumonia in 14, tuberculosis in 12, and lymphoma in 13 cases. Forty-six (30.6%) patients had at least one clinical diagnosis that was confirmed by autopsy, i.e., there was 40.6% agreement between pre- and postmortem findings. Forty-six (30.6%) patients had at least one clinical diagnosis that was not confirmed at autopsy, whereas 41 (27.3%) had at least one AIDS-related or unrelated disease that was not suspected clinically. The results obtained by limited autopsy are principally comparable to those achieved by full necropsy, with the advantages of decreasing the contagious risk, saving cost and time, including a rapid final diagnosis, and easily obtaining the consent for postmortem examination so that necropsy studies may be performed on a larger number of patients, thus contributing to a better understanding of the spectrum of HIV infection in our environment.

Pneumoccocal vaccination of HIV-positive individuals is recommended to prevent pneumococcal infection. We present a case of a 44-year-old HIV-infected male who came to the emergency room with bacterial pneumonia and sepsis. The patient also had a history of HBV and HCV infection. He expired in the emergency room and blood cultures were positive for Streptococcus pneumoniae. The autopsy confirmed the clinical diagnosis and, in addition, hepatitis C-related cirrhosis and splenic abnormalities. The patient had no history of opportunistic infections. His CD4 count 3 months prior to coming to the emergency room was 216 cells/microL with a viral load of 1,270 copies/mL. The patient had received Pneumovax two years before his death. The organism isolated from blood cultures was Streptococcus pneumoniae isotype 3, a strain included in Pneumovax. This is a case of pneumococcal vaccine failure with a fatal outcome in a person with an HIV infection and hepatitis C-related liver cirrhosis.

Effective antiretroviral therapy initially resulted in large decreases in hospitalization rates of HIV-infected patients. The goal of this study was to determine whether these gains were being maintained in 2001. A cross-sectional study of hospital admission characteristics during four time periods was performed. All patients receiving care at the HIV clinics of New York Presbyterian Hospital-Cornell Medical Center (NYPH) in New York City were included. In 1995, 883 outpatients were receiving care for HIV infection at NYPH; this increased to 1990 outpatients by 2001. Demographic and laboratory information was obtained for these outpatients, and diagnoses were recorded for all patients requiring hospitalization on at NYPH during the time periods January 1 through June 30, in 1995, 1997, 1999, and 2001. The incidence of hospital admission declined in all four time periods: 1995 (95 per 100 patient-years [pt-yr]), 1997 (48 per 100 pt-yr), 1999 (38 per 100 pt-yr, p < 0.05), and 2001 (25 per 100 pt-yr). The incidence of bacterial pneumonia and opportunistic infections (OIs) decreased in all four time periods. The median hospitalization were CD4(+) cell count for outpatients increased from 231 (1995) to 364 (2001). Important predictors of hospitalization were CD4(+) < 200, and IVDU as an HIV risk factor. Since 1995 and the introduction of highly active antiretroviral therapy, continuing increases in CD4(+) cell counts of outpatients has been reflected in persistent declines in hospitalization rates. Large decreases in OIs and pneumonia have been minimally offset by stable rates of hospital admissions for diagnoses such as hepatitis, cirrhosis, and cellulitis.

Human immunodeficiency virus (HIV)infection is usually followed by opportunistic infections, especially in the full-blown acquired immunodeficiency syndrome (AIDS). This study details the histopathological changes of different organs in relation to HIV infection, with particular emphasis on the opportunistic infections. Various organs from seventeen HIV-infected patients were collected by necropsy and analyzed for histopathological changes. The major histopathological changes included cytomegalovirus infection, cryptococcosis, penicilliosis, bacterial pneumonia, cryptosporidiosis, pneumocystosis, candidiasis, tuberculosis, granulomatosis of unknown etiology, early cirrhosis and chronic active hepatitis. General organ changes from seventeen cases of HIV-infected patients were described and discussed.

This case-control study assessed risk factors and prognostic indicators of 350 episodes of bacterial pneumonia in 285 HIV-infected patients. On univariate analysis, intravenous drug abuse (p<0.001), regular cigarette smoking (p<0.001), cirrhosis (p=0.04), and history of a previous episode of pneumonia (p=0.04), were risk factors for community-acquired episodes of bacterial pneumonia, whereas length of hospitalization (p=0.01) was a risk factor only for nosocomial bacterial pneumonia. The small amount of circulating T CD4+ cells, (<100/mmc) was a risk factor in both groups of pneumonia (p<0.05). Stepwise logistic regression analysis revealed that IVDA in community-acquired episodes and low levels of circulating T CD4+ cells, both in community-acquired and hospital-acquired episodes, were independent risk factors for the development of bacterial pneumonia. The case-fatality rate observed in our study was 27%. On stepwise logistic regression analysis, T CD4+ cell counts >100/mmc (p<0.02), neutropenia (p=0.04), PO2 arterial level <70 mmHg (p=0.01), and Karnofsky score <50 (p=0.04) were independent indicators of mortality. According to a personally developed prognostic score, 211 episodes of pneumonia (60%) were classified as mild, 63 (18%) as moderate, and 76 (22%) as severe. Clinicians must carefully evaluate those variables that can influence the prognosis of bacterial pneumonia to make early identification of affected patients and to promptly establish the most appropriate therapeutic strategy in each case.
