Because previous studies have suggested an important link between eosinophilia and immunologic reactivity, we investigated various components of the immune system in a large number of patients with the idiopathic hypereosinophilic syndrome (HES) to elucidate a possible role for immunologic phenomena in the etiology and pathogenesis of this disease. Immunoglobulin G, A, or M levels were only rarely abnormal. However, in 8 of 21 (38%) patients with HES, IgE levels were markedly elevated suggesting an association of an IgE-mediated mechanism with eosinophilia in this subgroup. Severe dermatographism was present in three fourths of patients, and 2 patients with intermittently elevated histamine levels manifested an unusual form of immediate-pressure urticaria. Serum complement determinations showed elevated C4 and C3 levels in 27% and 77% of patients, respectively. Antigen-antibody complexlike material measured by C1q binding was elevated in the serum of 7 of 22 (32%) patients; this finding may relate to the known ability of eosinophils to avidly phagocytose antigen-antibody complexes. When compared with normals, lymphocytes from patients with HES showed a variety of abnormalities of lymphocyte surface receptors and lymphocyte function. Thus, patients with HES demonstrate a variety of immunologic abnormalities which may be related primarily or secondarily to the pathogenesis of this syndrome.

Thirty-two asthmatic children, mean age 9.6 years (range: 6-14 years), were studied by oral challenge with acetylsalicylic acid (Aspirin), and their PEFR was recorded at 30 min intervals for 3 hr. They had been asthmatic for a mean of 7.1 years. Other allergic symptoms (urticaria, rhinitis or atopic dermatitis), were present in 81% of the patients, and a family history of atopy in 94%; the mean blood eosinophilia was 590 cells per mm3. In three children aspirin induced a fall in PEFR values less than 8% which was non-significant. In the group as a whole there was an increase in the PEFR values of 13.9%, 150 min after aspirin challenge. These values where subjected to statistical analysis (Kolmogorov-Smirnov, Student's and Wilcoxon tests), which showed this increase to be significant at a level of P = 0.001. Possible mechanisms involving prostaglandin synthetase inhibition by aspirin are discussed as an explanation for this increase.

Clinical and laboratory data were extracted from the medical records of 285 consecutive children after completion of their evaluations for suspected atopic disease. Blood eosinophilia, determined from a routine complete blood count, was present in more than 60% of patients tested. Nasal smear for eosinophils or a direct eosinophil count provided little additional evidence of atopic reactivity in simultaneously tested patients. Total serum IgE concentration was elevated in 75% to 81% of the children with asthma, nasal allergy and atopic dermatitis and an elevated serum IgE concentration or blood eosinophilia, or both, was noted in 85% of the patients studied. Selective IgA deficiency was documented in three children and hyperimmunoglobulinemia was found in 20 others. Serum complement activity was normal in 10 children with persistent urticaria, allergy, IgE, eosinophilia, immunoglobulins, complement.

Twenty-seven patients with serious gram-negative infections were treated with ticarcillin in an average daily dosage of 237 mg/kg (range, 174 to 307 mg/kg). Ticarcillin was bactericidal for all infecting organisms in concentrations ranging from 31.2 to 125 mug/ml. Five of 8 patients (62%) with overwhelming Pseudomonas pneumonia were cured or improved, and 9 of 12 (75%) were cured of pneumonia caused by other gram-negative organisms. Of six extrapulmonary infections caused by Pseudomonas, five (83%) were cured or improved. In seven cases, the infecting organism reisolated during therapy was more resistant to ticarcillin than the primary isolate. The serum half-life of ticarcillin in three patients with renal failure was 11.2 +/- 1.0 h, and during hemodialysis it decreased to 6.3 +/- 1.8 h. There were two episodes of superinfection with resistant organisms. Thirteen patients (48%) manifested eosinophilia, one of whom had severe urticaria. Prolongation of bleeding time was attributable to ticarcillin in two patients. Ticarcillin appears to be effective for therapy of serious gram-negative infections in dosages 30 to 50% less than those recommended for carbenicillin.

Eleven patients with recurrent bacterial infections were found to have impaired neutrophil chemotaxis. The infections were primarily staphylococcal abscesses involving the skin and the respiratory tract. All patients had chronic eczematour dermatitis and an elevated level of serum IgE. The peripheral blood eosinophil count was equal to or greater than 10% of the circulating leukocytes in 10 of 11 patients. Associated findings in some patients included urticaria and oral or cutaneous Candida infection. These observations suggest a relationship between chronic dermatitis, elevated serum IgE level, eosinophilia, defective neutrophil chemotactic responsiveness, and recurrent pyogenic infections of skin and lungs.

A six-year-old girl with recurrent urticaria and angioedema, vasculitis, and probable renal disease exhibited marked blood eosinophilia, increased levels of serum IgE, circulating Clq precipitins, and hypocomplementemia with evidence of activation of complement by the classic pathway. Biopsies of skin and muscle revealed heavy infiltrations of the vessel walls with eosinophils. Immunofluorescence studies revealed deposition of IgM, IgE, and C3 in the vessel walls. Exacerbations of the disease were associated with an increase in the eosinophil count and a decrease in the serum levels of C4 and C3. Remission was achieved with corticosteroid therapy. This patient has many features in common with the syndrome of skin lesions, angioedema, and hypocomplementemia recently described in adults.

A profound defect in granulocyte chemotaxis was documented in an otherwise healthy 21-yr-old man who failed to localize granulocytes to an area of cellulitis during an allergic reaction to cephalothin. During the period of drug allergy, characterized by urticaria, eosinophilia, and profound hypocomplementemia, in vitro migration of the patient's granulocytes in the Boyden chamber was markedly impaired. Although devoid of hemolytic complement activity, the patient's serum possessed supranormal chemotactic activity, even following heat inactivation, suggesting the presence of chemotactically active complement split products. Chemotactic function improved concomitantly with steroid therapy and normalization of serum complement levels, and was entirely normal following clinical recovery and cessation of steroid therapy. The chemotactic abnormality noted in the patient's cells was reproduced in normal granulocytes by preincubation either with patient serum or with cobra venom-activated fresh (but not heated) normal serum, suggesting that in vivo exposure of granulocytes to activated complement was responsible for the patient's abnormal chemotactic response. This mechanism may contribute to the increased infection propensity noted in other conditions characterized by in vivo complement activation, such as rheumatoid arthritis and systemic lupus erythematosis.

In a series of 136 cases of hydatid disease affecting various tissues and organs admitted to one surgical unit in the Medical City Hospital, Baghdad, and personally studied and treated by the author, the liver was involved in 94 cases (69-1 per cent) and intrabiliary rupture occurred in 15. Pain in the right upper abdominal quadrant associated with tenderness and rigidity, radiating to the back and right, shoulder, was the presenting feature in almost all the patients. Hectic fever was present in 14. Obstructive jaundice developed in all the patients at some stage of the illness, but was complete with clay-coloured stools in only half. Chills and rigors were present in 67 per cent, eosinophilia in 40 per cent, a positive Casoni's test in 87 per cent, itching with urticaria and weal formation in 20 per cent and a palpable mass in the liver in 67 per cent of cases. Operative treatment is mandatory in order to clean the mother cyst of hydatid membranes, debris and daughter cysts, to explore and clear the common bile duct and to ensure free biliary passage to the duodenum. Sphincterotomy is neither necessary nor advisable, and when the gallbladder is not invaded by the cyst it should be preserved.

Panipenem/betamipron (PAPM/BP) was given by 30 minutes drip infusion to 15 children with acute bacterial infections including 11 with acute pneumonia, 2 each with staphylococcal scalded skin syndrome and urinary tract infections. Good to excellent clinical responses were obtained in all of the 15 patients and bacterial eradications were obtained for all 12 strains identified in these cases. Urticaria considered to be drug related was observed in 1 patient. Slight elevations of GOT and GPT and eosinophilia were observed in 1 case each. From the above clinical results, it appears that PAPM/BP is a useful antibiotic for treatment of pediatric patients with various bacterial infections.

Eosinophilic gastroenteritis is a relatively uncommon disease of unknown etiology. Eosinophilic ascites resulting from significant serosal involvement is the rarest clinical subtype. The case reported here is of a 30-year-old male presenting with abdominal pain, diarrhea, and ascites. His personal history included childhood asthma, allergic rhinitis, and recurrent urticaria. The clinical picture was characterized by peripheral eosinophilia and eosinophilic infiltrates of the stomach and small bowel. Computed tomogram (CT) of the abdomen showed generalized thickening of the gastric and small bowel wall. Paracentesis revealed exudative ascites rich in eosinophils. The patient experienced an impressive response to steroid therapy.
