Unclear pulmonary infiltrates with eosinophilia, a problem of differential diagnosis. HISTORY AND ADMISSION FINDINGS: A 60-year-old woman was admitted for the diagnosis of pulmonary infiltrates. A year before she had been exposed to tuberculosis when working as a doctor in Manila, the Philippines. Ten days before admission she had spent 10 days in Sao Paulo, Brazil. On admission she complained of fatigue, dry cough and nocturnal sweating. Her body temperature was 37.8; C. At auscultation of the chest fine rales were heard with diminished percussion sounds over both lungs. INVESTIGATIONS: The chest radiogram showed bilateral apical infiltrates. Blood count indicated normal white and red cells, but platelets were raised to 606 x 10 9/l. The differential blood count revealed an eosinophilia of 30%, ESR was raised at 91 mm/h and C-reactive protein increased to 103 mg/l. Angiotensin-converting enzyme, IgG, IgA, IgM, IgE, C3 and C4, paraproteins, antinuclear antibodies and double-strand DNA antibodies were all within normal limits. There was no direct or indirect evidence of tuberculosis and no parasites were found in sputum, stool, urine and blood. DIAGNOSIS, TREATMENT AND COURSE: After bronchoscopy with bronchial biopsy had failed to establish a diagnosis, an open lung biopsy with partial lung resection was performed. This revealed histologically an eosinophilic pneumonia with intra-alveolar protein precipitation and multinucleated giant cells, as well as interstitial fibroblast proliferation without demonstrable mincroorganisms. Under cortisone administration there was striking improvement of symptoms within a few days, and C-reactive proteins fell to 3 mg/l, ESR to 25 mm/h and the eosino-philia to 2%. CONCLUSION: Eosinophilic pneumonia should be included in the differential diagnosis of unclear pulmonary infiltrations with eosinophilia, once parasitological and malignant diseases, tuberculosis and allergic pulmonary aspergillosis have been excluded.

An increasing number of human cases of gnathostomiasis have been reported in Sinaloa, Mexico, most of whom have a custom of eating of raw fish dishes such as 'cebiche'. Here we report five adult patients, three women and two men, having an acute episode of vomiting and abdominal pain a few minutes after eating a dish of cebiche prepared from a spotted sleeper perch (Eleotris picta) fished from a nearby lake in southern Sinaloa. All five patients experienced acute throat pain, chest and joint pains, headache and fever. One patient, a 55-year-old male, was hospitalized with suspected pancreatitis and pneumonia. By 8-9 days later, all five patients developed between three and 12 edematous, migrating skin lesions on the back, abdomen, upper and lower extremities, face, eye and scalp. By ELISA, all of them were sero-positive to Gnathostoma doloresi antigen and had elevated IgE levels. Eosinophilia was found in two patients. These patients lived in an agricultural and fishing community. In this community we carried out a sero-epidemiological survey and study of living conditions in a random sample of 309 individuals distributed in 74 households. Frequent consumption of raw fish was reported in 36% of households, and 12 individuals had a clinical history of migrating skin lesions. The sero-prevalence to Gnathostoma antigens was 34.95%. Five fish species and four species of ichthyophagous birds collected from three lakes in the village and a nearby estuary were infected with the advanced third-stage larvae of G. binucleatum, a species found in Ecuador and Mexico. The results describe the first known outbreak of acute gnathostomiasis on the American continent.

The levels of leukotriene E4 (LTE4) of the urine were determined in 24 pediatric patients with infectious diseases due to respiratory syncytial virus (RSV), i.e., bronchitis, pneumonia, and bronchiolitis, and compared with those in controls without allergic disease. The level for LTE4 of the acute-phase urine was 620+/-562 pg/mg. cr in the pediatric patients infected with RSV, being significantly higher than 190+/-67 pg/mg. cr in controls (P<0.005). The levels for LTE4 of the urine in the recovery phase showed a tendency toward decrease, as compared to those in the acute phase. However, there was no significant difference in the level for LTE4 of the acute-phase urine between the presence and the absence of each of the following conditions: expiratory wheezing; the association of pneumonia; family history of allergic diseases; the association of atopic dermatitis; and a past history of expiratory wheezing. An allergological study also revealed that there was no significant difference in LTE4 level between the presence and the absence of peripheral eosinophilia or between the presence and the absence of the high total level for IgE of the serum or positivity for the specific IgE level in the serum. These results suggest that LT is involved with the pathological conditions of RSV infection, but there are no direct relation between atopic diathesis or expiratory wheezing and the amounts of LT production.

RSV is the primary cause of hospitalisation in the first year of life for children in most parts of the world, and nearly 100% of children in the USA are infected with the virus by 2 to 3 years of age. The agent is an enveloped RNA virus with a non-segmented single-stranded negative-sense genome. The viral genome encodes 8 structural and 2 non-structural proteins. Important structural proteins include the fusion (F) protein and the attachment (G) protein which are essential for viral penetration and attachment to the host cells. Both proteins are important in development of immune responses. The virus is estimated to cause 3000 to 4000 deaths annually. Primary infections are as a rule symptomatic. The spectrum of clinical manifestations ranges from mild upper tract illness, infection in middle ear which progresses to acute otitis media, croup, to apnoea in premature infants, pneumonia and bronchiolitis. Premature babies born at 30-35 weeks of gestation, infants with cyanotic congenital heart disease, HIV-infected subjects, and patients on intensive immunosuppressive therapy especially after bone marrow transplant are considered to be at risk for increased mortality and morbidity during RSV infection. The virus does not normally replicate outside of the bronchopulmonary tree and the infection is exquisitely restricted to the respiratory mucosa. However, development of extrapulmonary disease has been observed in certain T and B cell immunodeficiency states. The association of RSV with asthma and reversible reactive airway disease in early childhood has attracted significant attention. Recurrent wheezing for up to 5 to 7 years of age and established airway disease has been observed in a significant number of children with a strong family history of allergy, after primary infection or reinfection with RSV. Immune response to primary infection is relatively small but on reinfection, a significant booster effect with sustained immunologic reactivity is observed in serum and respiratory mucosa. Both CD(4)- and CD(8)-specific as well as Th(1)- and Th(2)-cell specific immune responses have been observed during human infection. In addition, proinflammatory as well as immunoregulatory cytokines and chemokines are induced in the respiratory tract after natural and induced (in vitro) infection. Significant progress has been made in understanding the role of Th(1) vs. Th(2), IgE, viral induced cytokines and chemokines in the mechanisms of pathogenesis of the disease, development of wheezing and in the prevention and treatment of the infection and its sequelae. Respiratory syncytial virus (RSV) is one of the commonest human viral infections, and virtually every child is infected by the third birthday. Because of its restricted mucosal immunopathology, and frequent association with bronchial hyperreactivity and development of wheezing, RSV has served as an important model to investigate mechanisms of mucosal immune responses and development of mucosal disease following infection. The importance of RSV in bronchopulmonary disease and development of bronchial hyperreactivity has been the focus of several recent symposia [Kimpen JL, Simoes EAF. Am J Respir Crit Care Med 2001; 163:S1-S6]. This brief report will only summarise, based on selected references, the historical landmarks of its discovery and current understanding of the mechanisms of immunity, and their possible role in the pathogenesis of bronchopulmonary disease.

The hyperimmunoglobulin E (HIE) (Job's) syndrome often has it onset in childhood and is characterized by markedly elevated serum IgE levels, chronic dermatitis and recurrent pyogenic infections. Lymphoid malignancies have most commonly been associated with this syndrome while the first case in the literature of carcinoma associated with HIE syndrome was a squamous cell carcinoma of the vulva, described by Clark et al. in 1998. We observed a male patient with Job's syndrome diagnosed at age three who presented with bone pain and a metastatic epithelial tumor of the bone revealed by biopsy. Diagnostic procedures aimed at detecting the primary site showed multiple mediastinal lymph nodes with lung and liver metastases on computed tomography scans and an extradural spinal metastasis at the upper thoracic level on magnetic resonance imaging. Although the patient refused a bronchoscopic procedure, a diagnosis of pulmonary adenocarcinoma was established on the basis of sputum cytology and the clinical aspects of tumor extent. Intravenous corticosteroids and palliative radiotherapy were given for the spinal metastasis. Palliative chemotherapy could not be started because of the patient's poor performance status as well as nosocomial fungal pneumonia and pseudomonal urogenital infection with bacteremia. Despite the antifungal and broad-spectrum antimicrobial treatments, the patient died of pseudomonal sepsis.

It is not unusual for patients with severe motor and intellectual disabilities to present with eating and swallowing disorders, and such patients often require long term enteral nutrition. These patients tend to receive all their nutrients in the form of a single nutrient solution that is administered over a long period, and there are concerns about the impact of the composition of these nutrient formulas on patient health. Therefore, it is very important that adequate care be taken when selecting a nutrient formula for patients of this type. In the present study we administered two types of enteral nutrient solutions and examined the effect of the differences in nutrient composition on the degree of oxidative stress experienced by human patients. Subjects were 5 patients (mean age: 27.2 years; male/female ratio: 4:1) with severe motor and intellectual disabilities who were incapable of oral feeding, and who were receiving long term enteral nutrition. The subjects were administered a standard elemental diet for 2 months, and this was followed by administration of an n-3 polyunsaturated fatty acid enriched enteral nutrient solution for three months. Results showed that the n-3 polyunsaturated fatty acid enriched diet improved serum concentrations of trace elements, protein synthesis, and the balance between n-6 polyunsaturated fatty acids and n-3 polyunsaturated fatty acids, which are essential fatty acids. At the same time oxidative stress was reduced, and serum IgE levels declined significantly. Patients with severe psychophysiological disorders often suffer from repeated bouts of pneumonia due to immune system suppression, and there are reports that such patients are subject to increased allergic diathesis. The present results indicated that the in vivo membrane damage induced by oxidative stress may be closely related to the onset of these disorders. The results also suggested that in addition to attaining an adequate understanding of the effect of each of the various nutrients in enteral nutrient formulas, it will also be important to consider not only trace elements but also fatty acid composition in the nutritional management of patients with such disorders.

A 62-year-old man with chronic hepatitis was admitted to the hospital because of severe asthma, fever, and a chest radiograph abnormality. He had previously been treated unsuccessfully with several antibiotics in another hospital. The chest radiographs and CT films showed multiple infiltrations along the bronchi and in the peripheral regions of both lungs. Aspergillus fumigatus was detected in a sputum culture and the non-specific serum IgE was elevated. Allergic broncho-pulmonary aspergillosis (ABPA) was suspected and then steroids were administered. Although the asthma symptoms improved after the steroid therapy, lung infiltration deteriorated rapidly, affecting both lungs, and cavitations appeared. We concluded that invasive aspergillosis had developed from ABPA. Itraconazole and amphotericin B were administered, resulting in gradual improvements in the bilateral infiltration seen in the chest radiographs. The patient underwent open lung biopsy to rule out systemic vasculitis. The histological diagnosis was organizing pneumonia without vasculitis and without aspergillus or other organisms. The pathological findings resulted from the intensive anti-fungal therapy. There is a possibility that the temporal steroid therapy may have affected the conversion of ABPA to invasive aspergillosis.

Hyper-IgE syndrome is a rare primary immunodeficiency disease characterized by recurrent staphylococcal skin abscesses, chronic eczematoid dermatitis, pneumonia, pneumatoceles, and extreme elevation of serum IgE. The most common pathogens are S. aureus, and C. albicans. Abnormalities of dentition, bone manifestations, and connective tissue disorders are also common features of the disease. The authors report here a 19-year-old female with hyper-IgE syndrome who developed necrotising fasciitis and toxic shock syndrome. Methicillin resistant S. aureus and S. pyogenes cultured from the skin lesions. Association of hyper-IgE syndrome with necrotising fasciitis is a rarity in the medical literature. In addition to the case report, the authors describe here the major immunologic and clinical manifestations of hyper-IgE syndrome.

Job's or hyper immunoglobulin E recurrent infection syndrome (Hyper-IgE syndrome) is a rare, often inherited multisystem disorder, characterized by cutaneous abscesses, pneumonia, elevated IgE levels and skeletal defects. We report a case of a 22-year-old man with Job's syndrome who presented with back pain. He was found to have diffuse large B-cell lymphoma involving his second lumbar vertebrae and spleen. Treatment with dose-adjusted EPOCH-rituximab (DA-EPOCH-R) chemotherapy achieved a complete remission after 4 cycles. A review of reported cases of lymphoma in Job's syndrome indicates an increase in relative risk of 259 (95% confidence interval 102, 416). The cause of the increased risk has yet to be defined but has similarities to a pathogenetic model of AIDS related lymphoma. In previous reports of lymphoma in Job's syndrome, patients presented with extranodal disease and had poor outcomes. With appropriate chemotherapy and hematological support, lymphoma associated with Job's syndrome can achieve complete remission.

A 50-year-old male, living in the rural distinct of Kagoshima Prefecture complained of high fever and fatigue. Chest X-ray showed ground glass opacities in the right lung field. His symptoms and radiographic findings were gradually improved by intravenous or per os administraions of some antibiotics intravenously or per os. Following the chest computed tomography one month later demonstrated ground glass opacities in the right lung field. Examinations of peripheral blood showed increased IgE level but no eosinophila. Bronchoalveolar lavage fluid obtained from B4 showed high proportion of eosinophils. Because of the positive finding for Ascaris suum in the assay of multi dot-ELISA for parasite, he was diagnosed as Ascaris suum infection. The patient was successfully treated with Alvendazol. This is a rare case of Ascaris suum infection causing eosinophilic pneumonia.
