Abstract
BACKGROUND Wiskott-Aldrich syndrome is an Inborn Error of Immunity characterized by thrombocytopenia, small platelets, severe eczema, recurrent infections, tendency to autoimmune diseases and neoplasms. The diagnosis of the syndrome can be difficult, especially when platelets are of normal size. CASE REPORT A three-year-old male patient was referred to a specialized sector of university hospital for presenting acute otitis media that progressed to sepsis by Haemophilus influenzae. At one month of age, he had been diagnosed with autoimmune thrombocytopenia, and splenectomy was performed at two years of age. During follow-up, three hospitalizations were necessary: an infection by Streptococcus pneumoniae, which progressed to sepsis; one due to exacerbation of eczema, isolating S. epidermidis; another due to fever of undetermined origin. The tests showed normal number of platelets after splenectomy, platelets always with normal size. At age four, tests were performed: IgE 3128 Ku/L; IgA, IgG, and normal anti-polysaccharide antibodies; decreased IgM; decrease CD19, TCD4, naïve T and B; increased TCD8; normal NK. A diagnostic hypothesis of "probable" WAS was made. Genetic research has identified the c.295C>T mutation in the WAS gene. CONCLUSIONS The case reported expressed a new mutation in the SWA gene, characterized by clinical manifestations of the mild phenotype of Wiskott-Aldrich syndrome, with thrombocytopenia, platelets of normal size, and X-linked inheritance. It is important to establish the early diagnosis and treatment to offer a better quality of life in these patients.

Abstract
CD40 ligand (CD40L) deficiency is a rare inborn error of immunity presenting with heterogeneous clinical manifestations. While a detailed characterization of patients affected by CD40L deficiency is essential to an accurate diagnosis and management, information about this disorder in Latin American patients is limited. We retrospectively analyzed data from 50 patients collected by the Latin American Society for Immunodeficiencies registry or provided by affiliated physicians to characterize the clinical, laboratory, and molecular features of Latin American patients with CD40L deficiency. The median age at disease onset and diagnosis was 7 months and 17 months, respectively, with a median diagnosis delay of 1 year. Forty-seven patients were genetically characterized revealing 6 novel mutations in the CD40LG gene. Pneumonia was the most common first symptom reported (66%). Initial immunoglobulin levels were variable among patients. Pneumonia (86%), upper respiratory tract infections (70%), neutropenia (70%), and gastrointestinal manifestations (60%) were the most prevalent clinical symptoms throughout life. Thirty-five infectious agents were reported, five of which were not previously described in CD40L deficient patients, representing the largest number of pathogens reported to date in a cohort of CD40L deficient patients. The characterization of the largest cohort of Latin American patients with CD40L deficiency adds novel insights to the recognition of this disorder, helping to fulfill unmet needs and gaps in the diagnosis and management of patients with CD40L deficiency.

Abstract
Objective: To report a case of a child with primary immunodeficiency who at eight years developed digestive symptoms, culminating with the diagnosis of a neuroendocrine tumor at ten years of age. Case description: One-year-old boy began to present recurrent pneumonias in different pulmonary lobes. At four years of age, an immunological investigation showed a decrease in IgG and IgA serum levels. After the exclusion of other causes of hypogammaglobinemia, he was diagnosed with a Common Variable Immunodeficiency and started to receive monthly replacement of human immunoglobulin. The patient evolved well, but at 8 years of age began with epigastrium pain and, at 10 years, chronic persistent diarrhea and weight loss. After investigation, a neuroendocrine tumor was diagnosed, which had a rapid progressive evolution to death. Comments: Medical literature has highlighted the presence of gastric tumors in adults with Common Variable Immunodeficiency, emphasizing the importance of early diagnosis and the investigation of digestive neoplasms. Up to now there is no description of neuroendocrine tumor in pediatric patients with Common Variable Immunodeficiency. We believe that the hypothesis of digestive neoplasm is important in children with Common Variable Immunodeficiency and with clinical manifestations similar to the case described here in the attempt to improve the prognosis for pediatric patients.

Abstract
We report a case of a 14-year-old girl that presented headache, amaurosis, drowsiness, fever, vomiting and diffuse reduction of muscle strength. She had been diagnosed with ADEM one year before and had a previous diagnosis of Toll-Like 3 receptor deficiency. Cerebrospinal fluid analysis revealed pleocytosis (28/mm3, 12/mm3 red blood cells, 70% lymphocytes cells, 2% monocytes cells, 28% neutrophils), normal total protein (38 pg/mL) and normal glucose level (53/mm3). Studies for CSF oligoclonal bands and serum anti-MOG were negative but polymerase chain reaction (PCR) testing was positive for herpes virus 1. In the first ADEM episode, PCR for herpes virus was also positive. Magnetic resonance imaging (MRI) of the brain revealed disseminated hyperintense lesions on T2-weighted and FLAIR images in the white matter of frontal, parietal and temporal lobes, corresponding to extensive asymmetric areas of demyelination that produced mass effect and gadolinium enhancement. Electroencephalography demonstrated irregular diffuse and generalized slow-wave activity with predominance in frontal region. The diagnosis of multiphasic disseminated encephalomyelitis (MDEM) triggered by herpes simplex virus was made. Herpes virus is a neurotropic virus that can cause a wide variety of neurological infection-triggered autoimmune disorders and that is particularly damaging to the central nervous system in situations of impaired immune system. TLR3 is expressed in astrocytes and dendritic cells of the central nervous system and is essential for natural immunity to herpes simplex. TLR3-deficient patients have already been described with herpes simplex encephalitis. TLR3 deficiency may predispose and explain autoimmune and demyelinating manifestations induced by herpes virus. The association of multiphasic disseminated encephalomyelitis triggered by herpes virus in a patient with TLR3 deficiency has not been previously reported in the literature.

Abstract
BACKGROUND Hospital-acquired infection, often with Staphylococcus aureus, is an important complication in intestinal transplant. CLINICAL CASE A 2-year-old girl underwent small bowel transplantation owing to a small bowel volvulus. On the first postoperative day, lymphocyte phenotypes, serum immunoglobulins and chemotactic and phagocytic activity of neutrophils were assessed in peripheral blood. A decrease in the ingestion phase of phagocytosis by neutrophils was identified, in comparison with the results of 20 healthy children. On the second day, the patient had low fever and, on the third, abdominal pain. In view of this, she underwent a laparotomy that revealed purulent ascites due to Staphylococcus aureus. Specific treatment resulted in rapid regression of the infectious condition and good evolution of the patient. CONCLUSIONS A decrease in the ingestion stage of phagocytosis by neutrophils preceded staphylococcal purulent ascites clinical manifestations, and immunologic assessment contributed to early diagnosis and treatment of the infection. We believe evaluation of neutrophilic activity is important in patients undergoing intestinal transplantation in order for possible hospital-acquired infections to be early diagnosed.

Abstract
In the last few years, new primary immunodeficiencies and genetic defects have been described. Recently, immunoglobulin products with improved compositions and for subcutaneous use have become available in Brazil. In order to guide physicians on the use of human immunoglobulin to treat primary immunodeficiencies, based on a narrative literature review and their professional experience, the members of the Primary Immunodeficiency Group of the Brazilian Society of Allergy and Immunology prepared an updated document of the 1st Brazilian Consensus, published in 2010. The document presents new knowledge about the indications and efficacy of immunoglobulin therapy in primary immunodeficiencies, relevant production-related aspects, mode of use (routes of administration, pharmacokinetics, doses and intervals), adverse events (major, prevention, treatment and reporting), patient monitoring, presentations available and how to have access to this therapeutic resource in Brazil.

Abstract
BACKGROUND The presence of cryoglobulins in patients with chronic kidney disease (CKD) on hemodialysis is well described. However, the generation of cryoglobulins during the dialysis treatment has yet to be established. The aim of the present study was to determine the presence of serum cryoglobulins over time in the dialysis treatment in patients with CKD not infected with hepatitis C virus (HCV). METHOD Peripheral blood samples were collected at the beginning of dialysis treatment and at 30, 60, 90 and 120 days afterwards. Cryoglobulins were defined by the presence of immunocomplexes that precipitated in vitro with exposure to cold and resolubilized when rewarmed. The components of the cryoprecipitate were analyzed by radial immunodiffusion. RESULTS In this study, 14 patients were included: 11 male and three female, aged 28-88 years, with mean time on hemodialysis of 57 ± 36 days at baseline. The presence of cryoglobulin, constituted by IgM, IgA, IgG and the C3 and C4 components of the complement, was observed in the serum of all patients at the beginning of hemodialysis. Sequence analyses showed that the amount of cryoprecipitate decreased during the dialysis treatment. CONCLUSION There was a high prevalence of mixed cryoglobulins in CKD patients at the beginning of hemodialysis, and the amount of cryoprecipitate decreased during the treatment.

Abstract
Objective: To evaluate the results of the tests used to identify the IgE mediated sensitization to Aspergillus fumigatus in patients with cystic fibrosis. Methods: This is a cross-sectional descriptive study with a convenience sample of 86 patients diagnosed with cystic fibrosis in the Reference Service in Cystic Fibrosis at a tertiary teaching hospital. The following tests were performed to assess the sensitization to A. fumigatus in patients with cystic fibrosis: Total serum IgE, eosinophil count, fungus detection through oropharyngeal swab or sputum culture, serum-specific IgE, and immediate-type hypersensitivity (IgE) skin tests. We compared the results of the different tests performed. Results: In 33 (38.4%) patients with cystic fibrosis, with ages ranging from 1 to 33 years (median of 8 years), the IgE-mediated A. fumigatus sensitization test results were: in 16 patients, there was an increase in serum-specific IgE (>0.35 kU/L); in 23, skin tests were positive; and six had sensitization in both tests. We observed two patients with eosinophilia (>1,000 eosinophils/mm3) and seven with increasing total serum IgE (>1,000 IU/mL), all of whom obtained negative results in skin tests and had no IgE increase specific to A. fumigatus. A. fumigatus was not detected in oropharyngeal swabs and/or sputum culture of any patients. Conclusions: We conclude that, among the tests used to assess sensitization to A. fumigatus in cystic fibrosis patients, both serum-specific IgE and immediate-type hypersensitivity (IgE) skin tests are required. Serum eosinophilia and respiratory secretion culture were not essential in this study.

Abstract
Objective: Ventilator-associated pneumonia (VAP) is the leading type of hospital-acquired infection in ICU patients. The diagnosis of VAP is challenging, mostly due to limitations of the diagnostic methods available. The aim of this study was to determine whether antibody-coated bacteria (ACB) evaluation can improve the specificity of endotracheal aspirate (EA) culture in VAP diagnosis. Methods: We conducted a diagnostic case-control study, enrolling 45 patients undergoing mechanical ventilation. Samples of EA were obtained from patients with and without VAP (cases and controls, respectively), and we assessed the number of bacteria coated with FITC-conjugated monoclonal antibodies (IgA, IgM, or IgG) or an FITC-conjugated polyvalent antibody. Using immunofluorescence microscopy, we determined the proportion of ACB among a fixed number of 80 bacteria. Results: The median proportions of ACB were significantly higher among the cases (n = 22) than among the controls (n = 23)-IgA (60.6% vs. 22.5%), IgM (42.5% vs. 12.5%), IgG (50.6% vs. 17.5%), and polyvalent (75.6% vs. 33.8%)-p < 0.001 for all. The accuracy of the best cut-off points for VAP diagnosis regarding monoclonal and polyvalent ACBs was greater than 95.0% and 93.3%, respectively. Conclusions: The numbers of ACB in EA samples were higher among cases than among controls. Our findings indicate that evaluating ACB in EA is a promising tool to improve the specificity of VAP diagnosis. The technique could be cost-effective and therefore useful in low-resource settings, with the advantages of minimizing false-positive results and avoiding overtreatment.

Abstract
AIM We analyzed data from 71 patients with chronic granulomatous disease (CGD) with a confirmed genetic diagnosis, registered in the online Latin American Society of Primary Immunodeficiencies (LASID) database. RESULTS Latin American CGD patients presented with recurrent and severe infections caused by several organisms. The mean age at disease onset was 23.9 months, and the mean age at CGD diagnosis was 52.7 months. Recurrent pneumonia was the most frequent clinical condition (76.8%), followed by lymphadenopathy (59.4%), granulomata (49.3%), skin infections (42%), chronic diarrhea (41.9%), otitis (29%), sepsis (23.2%), abscesses (21.7%), recurrent urinary tract infection (20.3%), and osteomyelitis (15.9%). Adverse reactions to bacillus Calmette-Guérin (BCG) vaccination were identified in 30% of the studied Latin American CGD cases. The genetic diagnoses of the 71 patients revealed 53 patients from 47 families with heterogeneous mutations in the CYBB gene (five novel mutations: p.W361G, p.C282X, p.W483R, p.R226X, and p.Q93X), 16 patients with the common deletion c.75_76 del.GT in exon 2 of NCF1 gene, and two patients with mutations in the CYBA gene. CONCLUSION The majority of Latin American CGD patients carry a hemizygous mutation in the CYBB gene. They also presented a wide range of clinical manifestations most frequently bacterial and fungal infections of the respiratory tract, skin, and lymph nodes. Thirty percent of the Latin American CGD patients presented adverse reactions to BCG, indicating that this vaccine should be avoided in these patients.

Abstract
PURPOSE To assess the chemotactic activity and phagocytic response of neutrophilic polymorphonuclear leukocytes among women in the first five days postpartum. METHODS A prospective, cross-sectional clinical-laboratory study was conducted. Data of 31 postpartum women during the first five days after vaginal delivery were compared with those of 24 healthy non-pregnant non-postpartum women matched for age. The inclusion criteria were postpartum, clinically and obstetrically healthy women; vaginal delivery, singleton pregnancy carried to term; non-hypertensive, hyperglycemic, allergic, malnourished or with autoimmune or neoplastic diseases; not having received vaccines or blood products in the last three months. The Control Group was chosen according to the same inclusion criteria but involving non-pregnant non-postpartum women. The chemotactic activity of neutrophilic polymorphonuclear leukocytes was assessed by determining the distance from directed migration to bacterial lipopolysaccharide, in three Boyden chamber assays. The phagocytic response was identified by assessing the Zymosan particles' ingestion in three assays carried out in Leighton tubes. The Student's t-test was used in the statistical analysis, adopting a 5% level of significance. RESULTS The chemotactic activity of neutrophilic polymorphonuclear leukocytes from postpartum women in the presence of homologous (73.2 ± 6.9) and autologous (78.6 ± 13.9) sera showed a significant increase compared to the values observed in the Control Group (64.1 ± 4.1 and 66.6 ± 5.4). Both chemotactic response and phagocytosis ingestion phase of neutrophilic polymorphonuclear leukocytes were significantly increased (p < 0.05) in postpartum women compared to healthy non-pregnant and non-postpartum women. CONCLUSION There was an increase in the chemotactic activity and phagocytic response of neutrophilic polymorphonuclear leukocytes during the first five days after vaginal delivery in women.

Abstract
OBJECTIVE To analyze pulmonary function parameters and pharmacodynamic response to a bronchodilator, as well as the prescription of bronchodilators, in cystic fibrosis (CF) patients. METHODS This was a retrospective cohort study involving patients 6-18 years of age, diagnosed with CF, and followed at a referral center between 2008 and 2010. We evaluated only those patients who were able to perform pulmonary function tests (PFTs). We analyzed FVC, FEV1, and FEF25-75%, expressed as percentages of the predicted values, prior to and after bronchodilator tests (pre-BD and post-BD, respectively), in 312 PFTs. Repeated measures ANOVA and multiple comparisons were used. RESULTS The study included 56 patients, divided into two groups: those whose PFT results spanned the 2008-2010 period (n = 37); and those whose PFT results spanned only the 2009-2010 period (n = 19). In the 2008-2010 group, there were significant reductions in post-BD FEV1 between 2008 and 2010 (p = 0.028) and between 2009 and 2010 (p = 0.036), as was also the case for pre-BD and post-BD FEF25-75% in all multiple comparisons (2008 vs. 2009; 2008 vs. 2010; and 2009 vs. 2010). In the 2009-2010 group, there were no significant differences between any of the years for any of the variables studied. Among the 312 PFTs, significant responses to the bronchodilator occurred in only 24 (7.7%), all of which were from patients for whom no bronchodilator had been prescribed during the study period. CONCLUSIONS In the CF patients studied, there was loss of pulmonary function, indicating progressive lung disease, over time. The changes were greater for FEF25-75% than for the other variables, which suggests the initial involvement of small airways.

Abstract
BACKGROUND Renal failure patients submitted to chronic hemodialysis can present with cryoglobulinemia. There are few studies on cryoglobulins in chronic hemodialysis patients. The aim of the present study was to determine the prevalence and to identify the components of cryoglobulins in chronic hemodialysis patients. METHODS Fifty-four patients on chronic hemodialysis were evaluated for the presence of cryoglobulins, after inclusion and exclusion criteria. The components of the cryoprecipitate were analyzed. RESULTS Cryoglobulins were detected in 83% (45/54) of the patients on chronic hemodialysis. The cryoprecipitate was constituted by IgG, IgM, IgA, and complement fractions C3 and C4. CONCLUSION We concluded that there was a high prevalence of cryoglobulins in chronic hemodialysis patients, and the cryoprecipitate was constituted by IgG, IgM, IgA, and complement fractions C3 and C4.

Abstract
Allergic reactions against GH are rare, and usually represented by the hypersensitivity type I (IgE-mediated). This type of reaction can be treated by desensitization. In this case report, we present a patient showing an allergic reaction soon after starting GH therapy mediated by immune complex (hypersensitivity type III reaction). In this condition, the attempt to perform the desensitization procedure can perpetuate immune complex deposition determining a life threatening renal and respiratory insufficiency.

Abstract
BACKGROUND: Surgical treatment of hemorrhagic complication in schistosomal portal hypertension in our hospital is an esophagogastric devascularization procedure with splenectomy. Infectious risks and immunological alterations imputed to splenectomy may have significant importance. To minimize the consequences of spleen absence, the use of subtotal splenectomy and spleen auto-transplantation were stimulated. AIM: To verify the immunologic alterations imposed by this procedure in our patients. METHOD: Twenty-eight patients with schistosomal portal hypertension and previous history of upper digestive bleeding due to esophagogastric varices rupture underwent elective esophagogastric devascularization and splenectomy. They were prospectively studied before esophagogastric devascularization procedure with splenectomy, 15 and 30 days, 3 and 6 months after the procedure. T and B-lymphocytes, CD4 and CD8 subpopulations were determinated by monoclonal antibodies. Immunoglobulins A, M, G and C3, C4 components of the complement were determinated by radial immunodiffusion. RESULTS: We observed important reduction of all immune cells, increase of IgG and normal levels of IgM, IgA, C3 and C4 at preoperative. CD4/CD8 relation was normal. Six months after esophagogastric devascularization procedure with splenectomy, significant increase in T-lymphocytes, CD4, CD8 and B-lymphocytes were observed. CD4/CD8 relation remained normal. We noted significant increase in C3. IgA, IgM, IgG and C4 had increased, but without significant difference. CONCLUSION: Esophagogastric devascularization procedure with splenectomy determines an increase in T and B-lymphocytes, CD4 and CD8 subpopulations without compromising immunoglobulins and components of complement levels.

Abstract
UNLABELLED The aim of this study was to evaluate immune function in acute stress in medical students before academic examinations. Twenty-five medical students were selected because they presented intense acute stress, evaluated by the presence of the following classic signs: cold hands, intense sudoresis in the extremities, generalized sudoresis, paleness, tachycardia, confused reasoning, nervous irritability, diarrhea, and sleep disorders in the hours preceding the examination (agitated sleep, insomnia). METHODS Immediately before the examination, peripheral blood was collected from the 25 students presenting acute stress to analyze T and B cells, CD4+ and CD8+ cells, immunoglobulins, and C3 and C4 complement components, as well as phagocytic activity in neutrophils and monocytes. These investigations were repeated in the same students in situations free of acute stress. The results of the two samples collected from each student were compared. RESULTS The means and standard deviations showed no significant differences for any of the parameters analyzed (p> or =0.01). CONCLUSION We conclude that acute stress did not cause changes in the lymphocyte subpopulations, phagocytic activity of neutrophils and monocytes, serum immunoglobulins, or C3 and C4 complement components in students participating in the present study. In conditions of basal chronic stress, acute stress may cause alterations in immune function.

Abstract
The aim of this study was to assess the presence of cryoglobulins, the constitution of the cryoprecipitate, as well as the possible etiology and clinical features in kidney transplant recipients. We excluded patients with clinical or laboratory evidence of autoimmune, liver or neoplasm disease, infections, blood transfusions or immunizations in the previous 3 months. Detection of cryoglobulins was obtained from the peripheral venous blood. In cases of cryoprecipitate formation it was analyzed using anti-IgG, anti-IgM, anti-IgA, anti-C3, and anti-C4 antibodies. The hepatitis C virus (HCV) was detected by the polymerase chain reaction. Thirty-nine patients were selected, of whom 23 were men and the overall mean age was 40.6 +/- 12.7 years. Cryoprecipitate was detected in 74.4% (29/39) patients. Among patients with or without cryoprecipitate formation, the serum creatinine values, the percentage of patients with proteinuria, and the posttransplantation times were similar. In patients with cryoglobulins, 37.9% (11/29) were HCV positive. The etiology was not determined for the other patients. The IgG, IgM, and IgA immunoglobulins and the complement fractions C3 and C4 were found in the cryoprecipitate. Their compositions were similar among patients with or without HCV. Few clinical features were associated with the presence of cryoglobulins, including deep venous thrombosis, cutaneous purpura and peripheral neuropathy. In conclusion, cryoglobulinemia was prevalent in kidney transplant recipients, but appeared to not affect graft function. HCV infection was the most frequently associated etiology and clinical features were infrequent.

Abstract
UNLABELLED Infections and malnutrition remain the main causes of infant mortality in developing countries. In protein-calorie malnutrition, immunologic responses are affected, which often facilitates infections. However, the presence of asthma and allergic rhinitis are not commonly recognized in malnourished individuals. The aim of this study was to evaluate serum IgE values in children with primary moderate protein-calorie malnutrition. METHODS The level of IgE in peripheral blood of 18 children between 2 and 4 old with moderate protein-calorie malnutrition and without associated parasitic infestation was compared with that of 15 well nourished children of similar age. IgE serum levels were measured by an immunoenzymatic method. RESULTS The median level of serum IgE in malnourished children was 69.30 ng/ml while the control group showed a mean level of 95.97 ng/ml. This difference was significant (p < 0.01). CONCLUSION Malnourished children show decreased serum IgE levels. This might be one of the adaptive mechanisms of malnutrition employed in an attempt to use energy and protein reserves for growth and other functions. Our results are coherent with the decrease in IgE mediated reactions in malnourished patients.

Abstract
OBJECTIVE To evaluate the presence of immune complexes and the phagocytes by polymorphonuclear neutrophils in patients with systemic lupus erythematosus, with and without disease activity. METHODS The peripheral blood of 55 subjects was analyzed. Ten of those subjects had disease activity, 15 had not disease activity, and 30 were healthy. We used radial immune diffusion to detect immune complexes. The phagocytic function was estimated by the ingestion of zymosan by polymorphonuclear neutrophils. RESULTS In this study we found the presence of immune complexes formatted of IgM, IgG, IgA, and complement component C3 and C4 in LES patients. The arithmetic average of zymosan particles ingested by the neutrophils incubated with homologous human serum and autologous human serum was significantly decreased (p<0.05) in the LES activity patients when we compare with the group without activity, and the control group. CONCLUSION We conclude that there are immune complexes in the LES patients with and without disease activity, and there is a reduction in the digestive step of the phagocytes by polymorphonuclear neutrophils in patients with disease activity. The conclusions of the present study are according with the pathogenesis of the disease and with the high mortality in these patients.

Abstract
Five patients with atopic dermatitis, three males and two females, aged 2 to 17 years, had positive reactions to air allergens (Dermatophagoides pteronyssinus and/or farinae). All the patients suffered from severe recurrent dermatophytosis that responded poorly to antifungal treatment. The results of immunologic evaluation by laboratory tests were normal, except for a decrease in the ingestion phase by mononuclear phagocytes. After diagnosis of immunodeficiency, ketoconazole shampoo was used prophylactically and at the very first signs of recurrence of dermatophytosis, systemic antifungal treatment was started, without concurrent use of macrolides and with monitoring of hepatic function. The fungal infections responded well to this treatment and the patients' quality of life markedly improved.
