Abstract
INTRODUCTION Diagnosis of specific molecular defects of Mendelian susceptibility to mycobacterial diseases (MSMD) patients is important with respect to their clinical outcomes and their response to therapy. The aim of this study was to perform functional tests on blood samples of a group of patients who were suspected of having MSMD. METHODS This study was performed on 11 cases who had mycobacterial infections and suspected MSMD. Whole blood cell culture was performed in presence of different stimulators. The supernatants were assayed for IFN-γ, IL-12p40 by ELISA method. RESULTS All patients presented with complications of BCG vaccine in the form of localised lymphadenitis or disseminated BCG infection and chronic mycobacterial osteomyelitis. Infections with Salmonella species occurred in two patients. In-vitro studies showed that 10 cases had impaired response to IL-12. However, the baseline levels of IL-12p40 were normal, while one of our patients may have a potential IFN-γ signalling defect or an IL-12p40 defect. CONCLUSIONS Early detection of MSMD and commencing of appropriate combination therapy could prevent severe or even fatal complications of uncontrolled mycobacterial infections.

Abstract
BACKGROUND Primary antibody deficiency (PAD) is the most common group of primary immunodeficiency disorders (PID), with a broad spectrum of clinical features ranging from severe and recurrent infections to asymptomatic disease. OBJECTIVES The current study was performed to evaluate and compare demographic and clinical data in the most common types of PAD. MATERIALS AND METHODS We performed a retrospective review of the medical records of all PAD patients with a confirmed diagnosis of common variable immunodeficiency (CVID), hyper IgM syndrome (HIgM), selective IgA deficiency (SIgAD), and X-linked agammaglobulinemia (XLA) who were diagnosed during the last 30 years at the Children's Medical Center, Tehran, Iran. RESULTS A total number of 280 cases of PAD (125 CVID, 32 HIgM, 63 SIgAD, and 60 XLA) were enrolled in the study. The median (range) age at the onset of disease in CVID, HIgM, SIgAD, and XLA was 2 (0-46), 0.91 (0-9), 1 (0-26), and 1 (0-10) years, respectively. Gastrointestinal infections were more prevalent in CVID patients, as were central nervous system infections in XLA patients. Autoimmune complications were more prevalent in HIgM patients, malignancies in CVID patients, and allergies in SIgAD patients. The mortality rate for CVID, HIgM, and XLA was 27.2%, 28.1%, and 25%, respectively. No deaths were reported in SIgAD patients. CONCLUSIONS SIgAD patients had the best prognosis. While all PAD patients should be monitored for infectious complications, special attention should be paid to the finding of malignancy and autoimmune disorders in CVID and HIgM patients, respectively.

Abstract
BACKGROUND AND OBJECTIVE Selective immunoglobulin A deficiency (SIgAD) is the most common primary antibody deticiency. Patients with SIgAD have a greater risk of concomitant autoimmune disorders than healthy individuals. The exact mechanism underlying the relationship between autoimmunity and SIgAD is not fully understood. The aim of this study was to evaluate potential associations between autoimmunity and specific clinical or immunological findings in patients with SIgAD. METHODS The study population comprised 57 symptomatic patients (65% males) with confirmed SIgAD who were referred to our center. Demographic data and history of autoimmunity were recorded both for patients and for their relatives. Comprehensive clinical and laboratory examinations were performed to investigate autoimmune complications in all the patients. RESULTS Autoimmune disorders were documented in 17 cases (29.8%; 9 males and 8 females). The most common manifestations were thyroiditis, vitiligo, and hemolytic anemia (3 cases each). Ten patients (17.5%) had a family history of autoimmunity. Significant associations were detected between autoimmunity and increased duration of follow-up (P = .003), serum level of IgM (P = .01), regulatory T-cell count (P = .03), and class-switched memory B-cell count (P = .01). Four cases of autoimmune SIgAD (23.5%) progressed to common variable immunodeficiency during the follow-up period (P = .006). CONCLUSIONS Autoimmune disorders, autoimmune cytopenia, and Ig subclass deficiency can lead to severe clinical manifestations in patients with SIgAD. Therefore, immunologists and pediatricians should be aware of these conditions.

Abstract
BACKGROUND This study was performed to evaluate association of gene polymorphisms among proinflammatory cytokines and susceptibility to chronic idiopathic urticaria (CIU). METHODS Ninety patients with prolonged urticaria more than 6 weeks were included as case group. Single nucleotide polymorphisms (SNPs) of IL-6 (G/C -174, G/A nt565) and TNF-α (G/A -308, G/A -238) were evaluated, using polymerase chain reaction (PCR); and the results were compared to the control group. RESULTS G allele was significantly higher in the patients at locus of -238 of promoter of TNF-α gene (p<0.001). Frequency of following genotypes were significantly lower in patients with CIU, compared to controls: AG at -308 and GA at -238 of TNF-α gene (p<0.05 and p<0.001, respectively), CG at -174 and GG at +565 of IL-6 gene (p<0.05). Additionally, following genotypes were more common among patients with CIU: GG at -308 and -238 of TNF-α gene (p<0.05 and p<0.001, respectively), GG at -174 and GA at +565 of IL-6 gene (p<0.05). CONCLUSIONS Pro-inflammatory cytokine gene polymorphisms can affect susceptibility to CIU. TNF-α promoter polymorphisms as well as IL-6 gene polymorphisms are associated with CIU.

Abstract
BACKGROUND Chronic granulomatous disease is a phagocyte defect, characterised by recurrent infections in different organs due to a defect in NADPH oxidase complex. This study was performed to investigate pulmonary problems of CGD in a group of patients who underwent computed tomography (CT) scan. METHODS Computed tomography scan was performed in 24 patients with CGD. The findings of the CT scan were documented in all of these patients. RESULTS Areas of consolidation and scan formation were the most common findings, which were detected in 79% of the patients. Other abnormalities in order of frequencies were as follows: small pulmonary nodules (58%); mediastinal lymphadenopathy (38%); pleural thickening (25%); unilateral hilar lymphadenopathy (25%); axillary lymphadenopathy (21%); bronchiectasis (17%); abscess formation (17%); pulmonary large nodules or masses (8%); and free pleural effusion (8%). CONCLUSION The pulmonary CT scans of the patients with CGD demonstrated a variety of respiratory abnormalities in the majority of the patients. While recurrent respiratory infections and abscesses are considered as prominent features of CGD, early diagnosis and precise check-up of the respiratory systems are needed to prevent further pulmonary complications.

Abstract
BACKGROUND Primary antibody deficiencies (PADs) are a heterogeneous group of disorders, characterised by increased susceptibility to recurrent bacterial infections. Common variable immunodeficiency (CVID) is the most important PAD from the clinical point of view and selective IgA deficiency (IgAD) is the most common PAD. However, the underlying gene defect in both is still unknown. As a recent study in Europe showed an association between a single nucleotide polymorphism (SNP) of AICDA gene with PADs, this study was performed to evaluate such an association in Iranian patients. METHODS Fifty-eight patients with PAD, including 39 CVID and 19 IgAD, as well as 34 healthy volunteers, were enrolled in this study. Genotyping was done in all groups for an intronic SNP in AICDA (rs2580874), using real-time PCR genotyping assay. RESULTS The less frequent genotype of AICDA in IgAD patients was AA, seen in 10.5% of the patients, which was much lower than the 30.8% in CVID patients and 38.2% in the controls. However, these differences were not significant. Indeed the GG genotype in the patients with PADs was seen in 20.7%, compared to 8.8% in the controls without any significant difference. CONCLUSIONS There was no significant association between the previously reported genetic variant of AICDA gene and the development of CVID or IgAD, but further multi-center studies are also needed.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder of unknown etiology; although infection and inflammation have recently been considered as important etiologic agents. A recent meta-analysis showed correlations between cytokine [interleukin-10 (IL-10) and tumor necrosis factor (TNF)] gene polymorphisms and IBS; however, it is still unknown whether patients with IBS have different cytokine profiles compared to healthy population. METHODS To determine the relationships between serum/plasma levels or mucosal expression of IL-10/TNF-α and IBS, we conducted a systematic review and meta-analysis based on case-control studies retrieved from PubMed and EMBASE search through August 2013. Standardized mean difference (SMD) was generated by using the inverse variance method. Heterogeneity was assessed based on I(2) values. KEY RESULTS Serum/plasma levels of TNF-α tended to be higher in IBS vs controls (p = 0.09); this reached significance in IBS subtypes vs controls and in female patients with IBS. However, serum/plasma levels of IL-10 were not significantly different in IBS patients vs controls. Further analysis of serum/plasma IL-10 levels in IBS subtypes did not show any difference; however, analysis based on gender showed a significantly lower serum/plasma IL-10 levels in male patients with IBS vs male controls (p = 0.02). Colonic IL-10 mRNA had a significantly lower expression in IBS vs control (p = 0.001). CONCLUSIONS & INFERENCES There is an imbalance of proinflammatory TNF-α, and anti-inflammatory IL-10, cytokines in IBS. Stratifying IBS patients based on cytokine profile may represent an opportunity for personalized treatment of this condition.

Abstract
BACKGROUND Primary immunodeficiency diseases (PIDs) are a group of heterogeneous inherited disorders, characterised by recurrent infections, autoimmunity and malignancy. Some PIDs such as hyper IgE syndrome (HIES) and Wiskott-Aldrich syndrome (WAS) may be initially presented as atopic dermatitis (AD), especially in its severe form, resulting in diagnostic delay and poor prognosis of patients. OBJECTIVE The aim of this study was to evaluate the frequency of PIDs among patients with severe AD and to determine factors that can help to raise suspicion towards these disorders. METHODS Seventy-five patients with a well-established diagnosis of severe AD were enrolled in this study. Initial immunological evaluations, including humoral and cellular investigation, were performed in all individuals. Patients underwent further investigations in a case of suspicion of a probable PID. RESULTS Among all patients with severe AD, five (6.6%) were diagnosed with HIES and one (1.3%) with WAS. Family history of PIDs, family history of death in early infancy, positive history of recurrent infections such as skin and respiratory infections, otitis media and sinusitis were observed significantly higher in patients with a diagnosis of PID. CONCLUSIONS The presence of an underlying PID could explain the poor prognosis and refraction to the treatment of some patients with severe AD. Several clinical and laboratory findings can help the physicians to focus towards PIDs which are more serious. Delay in diagnosis of PID cases with skin manifestation of AD without proper management may result in lower quality of life and higher morbidity and mortality rates.

Abstract
BACKGROUND Interleukin-1 (IL-1) seems to have an important role in early reactions towards microbes, while its genetic variability could affect this role in atopic patients who have a distressed immunity towards dermatological infections. METHODS Eighty-nine patients with atopic dermatitis (AD), who were referred to a main referral paediatric hospital, were enrolled in this study. Single nucleotide polymorphisms (SNP) of the following IL-1 cluster genes were assessed in this group of patients: IL-1α -889, IL-1β -511, IL-1β +3962, IL-1R Pst-I 1970, and IL-1RA Mspa-I 11100. The results were compared with a group of 140 healthy subjects from the same region. RESULTS Fourteen percent of the controls had TT homozygous genotype in IL-1R at position Pst-I 1970, while only 2% of the patients with AD had this genotype (p=0.005, OR: 0.14, 95%CI: 0.02-0.64). The CC homozygous genotype was the most common genotype in IL-1α position -889 and IL-1β at position +3962 in both groups of patients with AD and the controls, while the TC heterozygous genotype was the most common genotype in IL-1β at position -511 and IL-1R at position Pst-I 1970, with no significant difference between the two groups. CONCLUSIONS This study showed a significant negative association in the IL-1R Mspa-I 11100 TT homozygous genotype in the patients with AD.

Abstract
Expression of selected genes in hematopoietic stem cells has been identified as a regulator of differentiation of B cells in the liver and bone marrow. Moreover, naïve B cells expressing surface immunoglobulin need other types of genes for antigen-dependent development in secondary lymphoid organs. Many advanced molecular mechanisms underlying primary antibody deficiencies in humans have been described. We provide an overview of the mutations in genes known to be involved in B-cell development and their clinical consequences.

Abstract
BACKGROUND Hypozincemia could lead to a variety of defects in growth and the immune system, while it seems to be associated with increased rate of asthmatic attacks in children. METHODS This study was performed to assess the serum zinc level in 100 paediatric asthmatic patients in comparison with a control group. RESULTS Mean serum level of zinc in the asthmatic patients was 70.5±22.6 μg/dL, which was significantly lower than 80.9±16.9 μg/dL in the control group (p<0.001). Forty-two asthmatic patients (42%) had hypozincemia, while this rate was 12% in healthy children (p<0.001). There was a significant association between the zinc level and severity of asthma (p<0.001). However, no significant association was detected between the serum level of zinc and other factors, including control and treatment of the disease. CONCLUSIONS As for high rate of hypozincemia in the asthmatic children, evaluation of serum zinc level in asthmatic children could be suggested, while zinc substitution in the diet of those with hypozincemia could be recommended.

Abstract
BACKGROUND Congenital cystic adenomatoid malformations (CCAMs) are considered rare developmental anomalies of the lower respiratory tract. These are hamartomatous abnormalities of the lung with adenomatoid proliferation of cysts resembling bronchioles and ususally occur sporadically occur and unilaterally with single lobe involvement. METHOD A 6-year-old girl was admitted to our center because of prolonged fever and non-productive cough lasting3 months before admission. RESULTS The only other complaint was night sweating. She did not have dyspnea and did not mention any respiratory symptoms. On examination, coarse crackle and decreased lung sounds in the left side were detected. White blood cell count was 9.100 /µL, hemoglobin was 11.2 g/dL, erythrocyte sedimentation rate was 50 and C-reactive protein was 1+. IgA and IgM for hydatid cyst were tested and both were raised (14 and 1.4, respectively). CONCLUSION The patient underwent surgery, with the probable diagnosis of hydatid cyst but in operating room diagnosis was changed and it was adenomatoid cystic malformation. In follow-up, she was in good general condition without any post-surgical complaints (Fig. 3, Ref. 11).

Abstract
A girl who developed severe BCGitis and vaccine-derived poliovirus infection was discovered to have a novel deletion of RAG1. A neonatal screening program for SCID would identify affected infants at birth, before live vaccines are administered.

Abstract
BACKGROUND Common variable immunodeficiency (CVID) is a heterogeneous group of disorders characterized by decreased serum immunoglobulin levels and increased susceptibility to recurrent bacterial infections. There is increasing evidence that the type 1 helper T cell (T(H)1)/T(H)2 cell balance is shifted towards a T(H) 1-type immune response in patients with CVID. This study was performed to measure levels of soluble CD26 (sCD26) and CD30 (sCD30) as plausible markers of a dysregulated immune response in a group of patients with CVID. METHODS Twenty-five patients with CVID and 20 age- and sex-matched controls were enrolled in this study. A sandwich enzyme-linked immunosorbent assay was used to measure serum sCD26 and sCD30 levels. RESULTS The mean (SD) serum sCD26 level was significantly higher in patients with CVID than in controls (88.47 [59.82] ng/mL vs 28.31 [25.61] ng/mL, P = .001). Serum sCD30 levels were also significantly higher in patients with CVID than in controls (196.37 [169.71] ng/mL vs 30.72 [12.98] ng/mL, P < .001). Analysis of serum sCD30 levels in association with different clinical variables indicated that patients with splenomegaly and malignancy had significantly higher levels than patients without these disorders. However, serum sCD30 levels did not differ with bronchiectasis or autoimmunity. CONCLUSIONS The presence of increased serum levels of sCD26 and sCD30 in patients with CVID suggests that CVID patients have a polarized immune response towards a T(H)1-like phenotype, whereas the association between high levels of these markers and disease severity suggests that the soluble form could be used as a prognostic tool in CVID.

Abstract
BACKGROUND Allergic rhinitis is a complex polygenic disorder of the upper respiratory tract. Given that proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin (IL) 1 seem to play a role in the development of allergic rhinitis, we evaluated the associations between various single-nucleotide polymorphisms (SNPs) of the TNF and IL1 genes in a case-control study. METHODS The study population comprised 98 patients with allergic rhinitis. Genotyping was performed using polymerase chain reaction with sequence-specific primers for 2 TNFA promoter variants (rs1800629 and rs361525), 1 variant in the promoter region of IL1A (rs1800587), 2 SNPs in the IL1B gene (rs16944 and rs1 143634), 1 variant in the IL1 receptor (rs2234650), and 1 in IL1RA (rs315952). RESULTS Patients who were homozygous for the T allele of rs16944 in IL1B had an 8.1-fold greater risk of allergic rhinitis than those with the C allele. In TNFA, a significant relationship was also detected between rs1800629 and rs361525 and allergic rhinitis. Except for rs1800587 in IL1A and rs315952 in IL1RA, significant differences were found between the patient and control groups for all other SNPs. CONCLUSIONS We found that allelic variants in the TNFA and IL1 genes were not only associated with the risk of developing allergic rhinitis, but also affected disease course and severity.
