An 80-year-old woman being treated with anti-hypertensive drugs developed eruption and itching of the skin. High fever and lymph node enlargement subsequently developed in spite of discontinuing all antihypertensive drugs, and she was admitted to our hospital. At the initial examination, multiple papules were noted over the entire body, and the skin showed thickening and lichenification with scratch marks. There was also generalized enlargement of the superficial lymph nodes. From these findings, her condition was diagnosed as chronic prurigo due to drug allergy. Laboratory tests showed inflammatory findings, anemia and a high serum level of IgE. Analysis of the surface marker of peripheral lymphocytes revealed no abnormalities. Bacteriologic cultures of blood revealed methicillin-resistant Staphylococcus aureus (MRSA). Histologic examination of the lymph nodes revealed chronic reactive lymphadenitis with a follicular pattern. She was strongly suspected of having MRSA septicemia, and so combination chemotherapy with vancomycin, minocycline and cefoperazone/sulbactam was started. However, 1 month after initiation of chemotherapy, the low-grade fever, eruption and moderate inflammatory findings persisted, and culture of the eruptions revealed MRSA. The prurigo was therefore considered to be the source of the septicemia, and daily application of diflucortolone ointment containing 3% acetic acid was started. Thereafter, the clinical and laboratory findings showed a rapid improvement. MRSA infections usually occur in compromised patients who are receiving antibiotics during prolonged hospitalization. The present case, who did not have any underlying disease, indicates that old-age is also an important factor for the development of MRSA septicemia.

Definitions of shock types. Hypovolaemic shock is a state of insufficient perfusion of vital organs with consecutive imbalance of oxygen supply and demand due to an intravascular volume deficiency with critically impaired cardiac preload. Subtypes are haemorrhagic shock, hypovolaemic shock in the narrow sense, traumatic-haemorrhagic shock and traumatic-hypovolaemic shock. Cardiac shock is caused by a primary critical cardiac pump failure with consecutive inadequate oxygen supply of the organism. Anaphylactic shock is an acute failure of blood volume distribution (distributive shock) and caused by IgE-dependent, type-I-allergic, classical hypersensibility, or a physically, chemically, or osmotically induced IgE-independent anaphylactoid hypersensibility. The septic shock is a sepsis-induced distribution failure of the circulating blood volume in the sense of a distributive shock. The neurogenic shock is a distributive shock induced by generalized and extensive vasodilatation with consecutive hypovolaemia due to an imbalance of sympathetic and parasympathetic regulation of vascular smooth muscles.

Large T-cell lymphoma was diagnosed in a 13-year-old girl with hyperimmunoglobulinemia E syndrome (HIES). Her past medical history included severe dermatitis, recurrent pneumonia, urinary tract infections, mucocutaneous herpetic infections, fungal skin infections, and staphylococcal sepsis. The diagnosis of HIES, based on the clinical features and a serum IgE level of >20000 IU/ml, was established when the girl was 6 years old. This is the eighth case of lymphoma in a patient with HIES reported in the English-language medical literature. HIES has not usually been considered a predisposing factor for malignancy, but in view of the rarity of HIES and the young age of the patients, this association seems to be more than coincidental. A link between lymphoma and Epstein-Barr virus (EBV) infection in patients with HIES has been proposed. Serological tests for EBV in our patient were positive 6 years prior to the development of the lymphoma; however, examination for EBV DNA in the lymph node biopsy failed to detect EBV in the tumor.

This was a great save. The crew could easily have missed the presentation of anaphylaxis and let the window for treatment with epinephrine slip away. This patient was in anaphylactic shock. There were no signs that supported a traumatic injury, and that, combined with diaphoresis, urticaria and tachycardic central pulse, contributed to the suspicion of anaphylaxis. Anaphylaxis is classified as distributive shock. This type of shock is caused by profound systemic vasodilation, and the heart is unable to increase output enough to maintain blood pressure. Other causes of distributive shock include sepsis and spinal cord injury. It is rare to have both hypotension and wheezing in such cases. In an anaphylactic reaction, an allergen, such as a food protein, medication, insect venom or latex, is introduced into the body. The mast cells of the immune system have a protein on their surface called IgE antibodies (Immunoglobulin E). The mast cells are filled with histamines [table: see text] and leukotrienes, which are chemical mediators. These are released when the allergen reacts with the IgE antibodies. When these mediators are released, they cause smooth-muscle constriction in the respiratory and gastrointestinal tracts, resulting in wheezing, stridor, nausea, vomiting and diarrhea. They also cause vascular dilation, leading to edema and urticaria. Most patients will present with either profound vascular effect (shock) or wheezing; this is a rather rare presentation of a patient having both. The medication best suited to counteract the effects of these medicators is epinephrine. Epinephrine is an alpha- and beta-agonist, acting to constrict the vasculature and dilate the smooth muscles in the bronchial tree. Antihistamines can alleviate symptoms of anaphylaxis, but should only be used in addition to epinephrine, not as a substitute. In life-threatening reactions, epinephrine must be given quickly and in a form that the body can distribute. Use of the subcutaneous route with a solution mixed at 1:1,000 dilution is appropriate in most patients, but if the patient is in profound shock and not perfusing the skin (pale, cold, clammy skin), then a more diluted concentration must be given i.v. at a slow rate (1 cc every minute of the 1:1,000 dilution) until the patient recovers. If i.v. access is delayed or not available, give the 1:1,000 dilution intramuscularly, in the tongue or down the endotracheal tube. Refer to your local protocols for dosage, but the usual dose of epinephrine is 0.3-0.5 mg, or 0.01 mg/kg in a child. There are more than 40 million people in the U.S. with allergic histories that place them at risk for developing anaphylaxis. Each year over 5,000 deaths are attributed to anaphylaxis. The risk of death from anaphylaxis increases with a more rapid onset of signs and symptoms. Up to 25% of patients will experience a biphasic reaction. This means there is a recurrence of symptoms several hours after the initial reaction, and it is prudent to observe patients for a period of time following their initial treatment.

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.

Haemophilus somnus is an important cause of bovine respiratory disease and septicemia with all it's sequelae. The role of immune responses in protection and immunopathogenesis is not well understood. We showed that infection with bovine respiratory syncytial virus (BRSV) 6 days before H. somnus increased clinical scores and levels of IgE antibody to H. somnus over that of infection with H. somnus alone. To determine whether antigenic specificity of IgE responses differed from IgG responses, Western blots were done with sera from the infected calves, at 0 time and at 21 days post infection. Thus each calf was its own control. IgG antibodies recognized primarily a 40 kDa outer membrane protein (OMP) in whole cell H. somnus preparations and a 270 kDa immunoglobulin binding protein (IgBPs) in culture supernatants but generally not the 41 kDa major OMP (MOMP). IgE antibodies recognized primarily the 41 kDa MOMP in whole cell pellet preparations. Results were consistent among calves. With culture supernatants, IgE antibodies recognized both the 270 kDa IgBPs and the MOMP. Since some H. somnus strains from asymptomatic carriers (including strain 129Pt), do not have IgBPs and express a truncated MOMP (33 kDa rather than 41 kDa), reaction of strain 129Pt cells with serum from calves infected with H. somnus or BRSV and H. somnus was studied. IgE did not react with the truncated MOMP even at much lower (1:100) dilutions than in Western blots with virulent strain 2336 (serum dilution of 1:500). Reactions of IgE with the 40 and 78 kDa antigens in strain 129Pt were noted but since the major reactivities with the IgBPs and the MOMP were not detected, this strain may be useful for inducing protective rather than immunopathogenic responses.

The bacterium Neisseria meningitidis is the causative agent of meningitis and sepsis. A generally effective vaccine against N. meningitidis serogroup B is not yet available, but outer membrane vesicle vaccines are in development. These vaccines contain lipopolysaccharide (LPS). The inclusion of N. meningitidis wild-type LPS in a vaccine is controversial because of its high toxicity. Therefore, the adjuvant activity of a panel of different Toll-like receptor (TLR) agonists in combination with LPS-deficient meningococcal outer membrane complexes was compared after immunization of mice. The results demonstrate that TLR3, TLR4, TLR7, and TLR9 agonists enhance immune responses against LPS-deficient outer membrane complexes. Their adjuvant activity was characterized by higher levels of antigen-specific immunoglobulin G (IgG), IgG2a, and IgG2b; a higher IgG2a/IgG1 ratio; lower total IgE levels; and most importantly, higher serum bactericidal antibody titers compared to LPS-deficient outer membrane complexes alone.

Hyper IgE syndrome (Job's syndrome) is a rare multiorgan disease characterized by the triad: elevated serum IgE level, recurrent sinopulmonary infections, most often staphylococcal, and cutaneous cold abscesses starting in infancy. We report 21 years old patient with hyper IgE syndrome, diagnosed at age of 6 years on the basis of hyperimmunoglobulinaemia E and recurrent pulmonary and cutaneous infections. Now he was admitted because of pneumonia complicating with pneumatocele, which could not be resolved despite intravenous antibiotics. Surgical intervention was necessary. The postoperative period was complicated by Staphyloccocus aureus sepsis.

Histophilus somni (Haemophilus somnus) is one of the key bacterial pathogens involved in the multifactorial etiology of the Bovine Respiratory Disease Complex. This Gram negative pleomorphic rod also causes bovine septicemia, thrombotic meningencephalitis, myocarditis, arthritis, abortion and infertility, as well as disease in sheep, bison and bighorn sheep. Virulence factors include lipooligosaccharide, immunoglobulin binding proteins (as a surface fibrillar network), a major outer membrane protein (MOMP), other outer membrane proteins (OMPs) and exopolysaccharide. Histamine production, biofilm formation and quorum sensing may also contribute to pathogenesis. Antibodies are very important in protection as shown in passive protection studies. The lack of long-term survival of the organism in macrophages, unlike facultative intracellular bacteria, also suggests that antibodies should be critical in protection. Of the immunoglobulin classes, IgG2 antibodies are most implicated in protection and IgE antibodies in immunopathogenesis. The immunodominant antigen recognized by IgE is the MOMP and by IgG2 is a 40 kDa OMP. Pathogenetic synergy of bovine respiratory syncytial virus (BRSV) and H. somni in calves can be attributed, in part at least, to the higher IgE anti-MOMP antibody responses in dually infected calves. Other antigens are probably involved in stimulating host defense or immunopathology as well.

Churg-Strauss syndrome (CSS) is a rare type of necrotizing vasculitis affecting small to medium-sized vessels typically characterized by asthma, lung infiltrates, necrotizing granulomas and hypereosinophilia. Herein, we describe a case of CSS presenting severe and aggressive course. A 35-year-old male patient with weight loss, dyspepsia, dyspnea and hemoptysis was admitted. The laboratory analyses indicated a remarkable eosinophilia, elevated levels of serum total IgE and positive cANCA. Thorax CT findings were suggestive of alveolar hemorrhage. Bronchoalveolar lavage revealed alveolar hemorrhage with eosinophilia and transbronchial lung biopsy showed eosinophilic vasculitis. Cardiac enzymes were increased and murmurs were audible revealing cardiomyopathy proven by echocardiography. Pulse cyclophosphamide and methyl prednisolone was immediately started. On the 21st day, intestinal perforation developed and urgent surgery was performed. During a follow-up, although a radiological improvement was observed in the chest X-ray, cardiac failure, peripheral neuropathy and skin lesions developed and high-dose intravenous immunoglobulin and anti-TNF therapy (adalimumab) were applied. Despite the therapy, he died from heart failure and septicemia at 68th day of therapy.
