Many questions are raised in this review about the role of adult donor granulocyte transfusions in the setting of overwhelming bacterial neonatal sepsis. There clearly exists a number of variables, which influence the survival and morbidity associated with bacterial sepsis. The important differences in these studies highlight the need for prospective large multicenter studies to definitely clarify these issues. Important criteria, which are yet to be established and which impact significantly, include the time of administration of adjuvant granulocytes, the number of granulocytes that need to be harvested, which group of neonates require early granulocyte transfusions, the best method for optimal and easy granulocyte collection, the frequency and intervals of granulocyte transfusions, and improved methods for the early identification of neonatal candidates who would benefit from the granulocyte transfusions. The benefits of granulocyte transfusions (ie, the improvement in morbidity and mortality) in septic neutropenic neonates must be weighed against the possible and reported side effects associated with such transfusions. Adverse reactions including graft-versus-host disease, CMV, HIV and hepatitis infection, fluid retention and pulmonary edema, blood group sensitization, and pulmonary insufficiency may all result from the use of granulocyte transfusions in a host who has evidence of developmental immaturity. All future studies must continue to evaluate these potential complications to balance and analyze the true benefits of survival with reported treatment results. Recently, a number of investigators including ourselves, have begun to examine the role of alternate adjuvant immunotherapy in enhancing neonatal host defense in the clinical setting of overwhelming bacterial sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

For diagnosing pulmonary disease on 82 occasions in 68 patients (64 males) aged 39 (23-73) years infected with HIV-1 we used flexible fiberoptic bronchoscopy (FFB) with bronchoalveolar lavage (BAL) or washing with or without transbronchial lung biopsy (TBB) and brushing. A clinical diagnosis of lower respiratory tract disease was obtained in 68/82 episodes (83%). An etiological diagnosis was reached by FFB in 59/82 episodes (72%). Pneumocystis carinii (PC), the dominating pathogen causing pneumonia in 54/82 episodes (66%), was detected by FFB in 51/54 (94%). In spite of being isolated in bronchoscopy material in 36/82 episodes (44%) cytomegalovirus (CMV) seemed to be the cause of pneumonia only in 2/36 (5%) episodes. Except PC and CMV, only bacteria (including mycobacteria) were found as infectious etiological agents. Kaposi's sarcoma and pulmonary edema were diagnosed in one patient each. For detection of PC in 37 episodes we compared staining of BAL fluid with indirect immunofluorescence (IF) using monoclonal antibodies (MoAB) with staining of BAL material by silver methenamine (Grocott). Staining with IF MoAB alone of BAL fluid only seemed to be even more sensitive than silver methenamine staining of BAL, TBB and brushing material. When using IF MoAB staining of BAL fluid, TBB and brushing added nothing to the result, except in the patient with Kaposi's sarcoma, diagnosed by TBB. Sputum investigation using IF MoAB for detection was increasingly adopted during the study time. It was very useful (sensitivity approximately 74%) and reduced the number of required FFBs.

Widespread vaccination has largely eliminated anthrax in Europe (the last case was reported in France in 1972) but the disease remains endemic in many developing countries. The usual cutaneous presentation (malignant pustules) is much more familiar than the various visceral manifestations including digestive tract, pulmonary or meningeal signs. We report a case of a 33-year-old immigrant living in France who was hospitalized for asthenia, dyspnoea, mucopurulant expectoration and moderate diarrhoea 3 days after a 3-month stay in Senegal and Gambia. The temperature was 39 degrees C at admission and blood pressure 110/70 mmHg. Crepitants were heard at the base of the right lung and the rest of the physical examination was normal. Blood was drawn for culture. Laboratory tests and the chest X-ray led to the diagnosis of pneumopathy and a treatment of amoxicillin and clavulanic acid was given with oxygenotherapy. The patient's temperature returned to normal but over the next 48 hours the dyspnoea worsened together with the black diarrhoea. The abdomen was painful. There were no skin lesions. The chest X-ray revealed an extension of the bilateral pulmonary images and bilateral pleural effusion. Laboratory tests revealed thrombopenia (platelet count 38,000/mm3) hyperleukocytosis (WBC 48,000/mm3) and haemolysis (Hb 4 milligrams). The diagnosis was made on the basis of the initial blood cultures which were positive for Bacillus anthracis. All other samples were negative, including HIV serology. Despite adapted antibiotic therapy (penicillin G, 8MU/day, was initiated on day 2), multiple organ failure occurred with septic shock and pulmonary oedema. The patient died in the intensive care unit on day 7. Fatal outcome due to anthrax is described in 25% of the visceral forms but reaches 100% in cases of septicaemia. The haemolysis observed in this case is not mentioned in the classical descriptions of anthrax. When treating septic syndromes in patients who have returned from endemic zones, clinicians should entertain the diagnosis of anthrax since the risk of fatal outcome is increased greatly in case of delayed diagnosis.

We present the pulmonary findings in 36 autopsies of children affected by the acquired immunodeficiency syndrome (AIDS). Twenty-three patients were male and 13 were female, ranging in age between 3 days and 13 years. Twenty children had human immunodeficiency virus (HIV)-positive parents or parents who were at high risk of exposure (intravenous drug abusers and prostitutes), five had a history of transfusion, and one had a history of renal transplantation and blood transfusion. Clinically, the patients presented with recurrent infections, failure to thrive, hepatosplenomegaly, fever, cough, and/or hemoptysis. Histologically, specific infectious processes were the most common finding (75% of cases), with Pneumocystis carinii pneumonia being the most prevalent type of infection, followed by bacterial pneumonia. Neoplastic conditions and lymphoid interstitial pneumonia were less frequent (approximately 10% of cases). In addition, in approximately 10% of the cases the pulmonary findings were non-specific (ie, pulmonary edema and atelectasis) and probably unrelated to HIV infection. Our findings suggest that specific infectious conditions constitute the most common type of pulmonary pathology in children with AIDS. However, because there is a small percentage of children with nonspecific findings, a transbronchial biopsy is important for proper evaluation before institution of therapy.

To examine intensive care unit (ICU) admission rates and diagnoses of patients with HIV infection, and to determine the outcomes of different critical illnesses, we analyzed data derived from the 63 patients who were admitted to an ICU from among the 1,130 adults with HIV infection who did not have AIDS at the time of enrollment in a multicenter prospective study. Patients were admitted and treated according to the judgment of their physicians. During 4,298 patient-years of follow-up for the entire cohort, there were 1,320 hospital admissions, of which 68 (5%) included admission to an ICU. Twenty-five (40%) of the patients admitted to the ICU died during that admission. Twenty-four patients (38%) were admitted with a principal diagnosis of lung disease; 11 had Pneumocystis carinii pneumonia (PCP), one of whom was coinfected with Aspergillus fumigatus and Legionella pneumophilia, and six of them (55%) died. Four had bacterial pneumonia, two had pulmonary edema caused by renal failure, and one each had pulmonary tuberculosis, pulmonary Kaposi's sarcoma, pneumothorax, adult respiratory distress syndrome, severe pulmonary fibrosis, cytomegalovirus pneumonitis, and metastatic adenocarcinoma to the lungs. Eleven of these 14 patients (79%) died. Thirty-nine patients had 44 admissions for nonpulmonary diagnoses, including gastrointestinal disorders (14 admissions), cardiovascular disorders (nine), sepsis syndrome (six), neurologic disorders (four), monitoring and ICU nursing care during or after a procedure (four), metabolic disorders (three), trauma (two), drug overdose (one), and unknown reasons (one). Nine (23%) of these patients died. Twenty-eight patients underwent mechanical ventilation, and 16 (57%) died. Seven (25%) had PCP (five died), seven had other primary pulmonary diseases (six died), and 14 were placed on mechanical ventilation for nonpulmonary disorders (five died). Survival did not correlate with CD4 count determined within 6 mo of admission to the ICU. In conclusion, the range of indications for critical care in patients with HIV infection is diverse. PCP accounted for only 16% of the ICU admissions, and mechanical ventilation for PCP and other pulmonary disorders was associated with a high mortality rate. In contrast, mechanical ventilation for nonpulmonary disorders, and admission to the ICU for nonpulmonary diagnoses was associated with a more favorable outcome.

With changes in the demographics of human immunodeficiency virus (HIV) infection, women and children are becoming the fastest growing group of newly infected patients. With longer survival after HIV infection, more women infected with HIV are becoming pregnant. Pulmonary disease is one of the most common presenting conditions in an AIDS-defining illness. Pneumocystis carini pneumonia and tuberculosis are the most common disorders that herald the onset of AIDS. They are also the most frequently encountered HIV-related pulmonary complications during pregnancy. Others have been rarely reported during pregnancy and include fungal infections (Cryptococcus neoformans, Histoplasma capsulatum, and Coccidioides immitus), bacterial infections (Haemophilus influenzae and Streptococcus pneumoniae along with Pseudomona aeruginosa), viral infections (CMV), opportunistic neoplasms (Kaposi's sarcoma, lymphoma) and miscellaneous conditions peculiar to HIV-infected individuals (nonspecific interstitial pneumonitis, lymphoid interstitial pneumonitis, isolated pulmonary hypertension, and pulmonary edema secondary to cardiac disease or drug abuse). Most of the data regarding the pulmonary complications of HIV infection come from studies in nonpregnant patients. The extent to which pregnancy affects the course of respiratory disease in HIV infection and vice versa is not well documented. Clinical presentation is usually not altered by pregnancy. Except for minor modifications mainly related to potential fetal effects, the diagnostic work-up and management are similar to those in the nonpregnant patient. The most important effect of pregnancy on these conditions remains the delay in diagnosis and treatment. A high index of suspicion should, therefore, be maintained. In addition, most prophylactic measures recommended in nonpregnant HIV-infected individuals also apply to pregnant women.

Practical approaches to the initial evaluation of solid organ transplant patients, BMT patients, and HIV-infected patients with pulmonary disease are summarized in Figures 2, 3, and 4. These algorithms are meant to be used as guidelines for the clinician. The clinical setting will ultimately determine the extent and speed of the evaluation. Patients who are recipients of solid organ transplants and have pulmonary symptoms may have focal or diffuse changes or may have normal chest radiographs. In all these groups, sputum is obtained by expectation. If a pathogen is found in any of the groups, it is treated. When no pathogen is found on sputum examination in patients with focal disease, empiric antibiotic therapy is given. If the patients do not improve on the empiric antibiotics, then bronchoscopy is performed. Some centers proceed directly to bronchoscopy before antibiotics are started in the hope of directing antibiotic therapy. Patients who have a normal CXR or diffuse infiltrates and no identified pathogen on examination of sputum undergo bronchoscopy, and the protocol is followed until a diagnosis is made (see Fig. 2). Patients who have received a BMT and who present with pulmonary symptoms are treated as shown in Figure 3. The CXR will reveal if the infiltrate is focal or diffuse. Those with focal infiltrates are treated with broad-spectrum antibiotics for 48 to 72 hours. If the symptoms and signs do not show some resolution, then bronchoscopy is usually performed. The effect of diffuse infiltrates in BMT patients depends to a large extent how far along in recovery from the transplant the patient is when they develop the infiltrates. During the first 30 days posttransplant, pulmonary edema commonly occurs, and the infiltrates may resolve with diuresis. If the patient is not clinically fluid overloaded or they do not respond to the diuretic therapy, then bronchoscopy with BAL is indicated. Finally, many HIV-infected patients may present with pulmonary symptoms. They may have a normal CXR or a diffuse or focal pattern (Fig. 4). All patients are subjected to sputum induction to identify a pathogen. If one is identified, it is treated. Should the patient not respond to treatment adequately or a pulmonary pathogen is not found, then bronchoscopy with BAL, protected specimen brush, or a transbronchial biopsy is attempted. The above schema is a general guideline to the initial evaluation of pulmonary disorders in the ICP. The respiratory abnormality is found in most of the cases if these algorithms are closely followed. If the patient does not improve or deteriorates further, additional diagnostic procedures such as video-assisted thorascopic lung biopsy or CT-directed transthoracic needle biopsy may be needed.

176 patients with HIV-infection and AIDS were examined. 77 of them underwent various surgical interventions the most frequent of which were: opening of abscess and phlegmons--14 (23%), biopsy of lymphatic nodes--10 (13.1%), appendectomy--5 (6.2%), condyloma excision--21 (27.2%), removal of uterus adnexa--2 (2.5%), pleural puncture--4 (5.9%), cholecyst- and splenectomy--5 (8.2%). Operations for stomach cancer (creation of gastroenteroanastomosis), extrauterine pregnancy, brain tumor (drainage of IV ventricle of the brain), penetrating wound of cornea were performed less often. 43 patients underwent emergency operations without preoperative preparation, 34 patients underwent elective operations. The causes of 6 deaths were secondary diseases (Kaposi's sarcoma, purulent processes, metastases, pulmonary edema). There were no complications and blood changes in postoperative period in infected patients. These patients were discharged in the same terms as non-infected patients. In patients with AIDS, especially in combination with other infections, fever persisted long after the operation. The wound healed by first intention in all the patients, but the sutures were removed on day 10-30. Immunologically, a high ratio T-suppressors/T-helpers existed. An increase in fibrinolytic activity without high tissues hemorrhage was observed.

Drug abuse is a growing problem in industrialized countries, opening the way to new diseases of the respiratory tract. It has been demonstrated that regular inhalation of cannabis has the same consequences as tobacco smoking. The same cannot be said for other drugs. Cocaine, amphetamines or crack expose the patient to particular toxic effects: in addition to barotrauma related to the administration route, syndromes of acute respiratory distress have been described. These result either from bronchial reactions, asthma exacerbation or eosinophil bronchopneumonia, or alveolar involvement: intra-alveolar bleeding, pulmonary edema or organized pneumonia. Respiratory complications induced by opiates, often used in injections, are related to central alveolar hypoventilation and/or the development of injury from pulmonary edema or pneumonia. The pathophysiology of these lesions is not perfectly understood. Besides these specific conditions, infection is a major problem in drug abusers, irrespective of the drug: bacterial pneumonia, tuberculosis, HIV infection are much more frequent in this high-risk group. Finally repeated intravenous injections of various drugs designed for oral intake can lead to severe complications such as pulmonary hypertension or toxic interstitial lung disease. Summarizing, respiratory diseases in drug abuses can take on a wide range of quite complex presentations. Occasional or regular use of illicit drugs can lead, not exceptionally, to severe respiratory complications requiring rapid management. Knowledge of the principal complications and the appropriate diagnostic procedures is indispensable.

Pleuropulmonary amebiasis is the common and pericardial amebiasis the rare form of thoracic amebiasis. Low socioeconomic conditions, malnutrition, chronic alcoholism, and ASD with left to right shunt are contributing factors to the development of pulmonary amebiasis. Although no age is exempt, it commonly occurs in patients aged 20 to 40 years, with an adult male to female ratio of 10:1. Children rarely develop thoracic amebiasis: when it does occur there is an equal sex distribution. The infection usually spreads to the lungs by extension of an amebic liver abscess. Infection may pass to the thorax directly from the primary intestinal lesion through hematogenous spread, however. Lymphatic spread is one possible route. Inhalation of dust containing cysts and aspiration of cysts or trophozoites of E histolytica in the lungs are some other hypothetical routes. The lung is the second most common extraintestinal site of amebic involvement after the liver. Usually the lower lobe, and sometimes the middle lobe of the right lung, are affected, but it may affect any lobe of the lungs. The patient develops fever and right upper quadrant pain that is referred to the tip of the right shoulder or in between the scapula. Hemophtysis is common. The diagnosis of thoracic amebiasis is suggested by the combination of an elevated hemidiaphragm (usually right), hepatomegaly, pleural effusion, and involvement of the right lung base in the form of haziness and obliteration of costophrenic and costodiaphragmatic angles. Infection is usually extended to the thorax by perforation of a hepatic abscess through the diaphragm and across an obliterated pleural space, producing pulmonary consolidation, abscesses, or broncho-hepatic fistula. Empyema develops when a liver abscess ruptures into the pleural space. Rarely, a posterior amebic liver abscess can burst into the inferior vena cava and develop an embolism of the inferior vena cava and thromboembolic disease of the lungs with congestive cardiac failure or corpulmonale. Diagnosis by finding E histolytica in stool specimens is of limited value. In a limited number of cases amebae might be found in aspirated pus or expectorated sputum. "Anchovy sauce-like" pus or sputum may be found. Presence of bile in sputum indicates that the pus is of liver origin. Serological tests are of immense value in diagnosis. Liver enzymes are usually normal and neutrophilic leucocytosis may or may not be found. ESR is invariably elevated. Anti-amebic antibodies can be detected by ELISA, IFAT, and IHA. Amebic antigen can be detected from serum and pus by ELISA. Detection of Entamoeba DNA in pus or sputum may be a sensitive and specific method. Pleuropulmonary amebiasis is easily confused with other illnesses and is treated as pulmonary TB, bacterial lung abscesses, and carcinoma of the lung. A single drug regimen with metronidazole with supportive therapy usually cures patients without residual anomalies. Aspiration of pus from empyema thoracis may be needed for confirmation and therapeutic purposes. The pericardium is usually involved by direct extension from the amebic abscess of the left lobe of the liver, sometimes from the right lobe of the liver, and rarely from the lungs or pleura. An initial accumulation of serous fluid due to reactive pericarditis followed by intrapericardial rupture may develop either (1) acute onset of severe symptoms with chest pain, dyspnea, and cardiac tamponade, shock, and death, or (2) progressive effusion with thoracic cage pain, progressive dyspnea, and fever. Chest radiograph, ultrasound examination, and CT scan usually confirm the presence of a liver abscess in continuity with the pericardium and fluid within the pericardial sac with or without the fistulous tract. Echocardiography may demonstrate fluid in the pericardial cavity. Patients should be cared for in the ICU and ambecides should be started without delay. Pericardiocentesis usually confirms the diagnosis and improves the general condition of the patient. Aspiration of the accumulated fluid should be performed urgently in cardiac tamponade; repeated aspiration may be needed. Surgical drainage should be done if needed. Acanthamoeba, a free-living ameba, may also infect the lungs in the form of pulmonary nodular infiltration and pulmonary edema in association with amebic meningoencephalitis in immunocompromised patients. It usually spreads to the meninges of the brain by way of the blood from its primary lesion in the lung or skin. Early diagnosis and institution of treatment may be life saving for these patients. A literature review shows that HIV/AIDS patients are not prone to infection with E histolytica. It is now clear that there are an increasing number of HIV-seropositive patients among amebic liver abscess patients, however, which suggests that although the incidence of intestinal infection is not high among HIV-seropositive or AIDS patients they are more susceptible to an invasive form of the disease.
