<b>Background</b>: <span>Miscarriage is a common phenomenon complicating more than half of</span> pregnancies. Recurrent Pregnancy Loss (RPL) is defined as three or more pregnancies lost before the twentieth week of gestation. It is believed that abnormality in maternal immune reaction to fetus and sharing of HLA antigens might be associated with RPL. <br/><b>Objective</b>: <span>To investigate the effect of HLA-DRB1 sharing between the couples with</span> recurrent pregnancy loss on the pregnancy outcome after leukocyte therapy. <span><br/><b>Methods</b>:</span> Sixty primary RPL women who were immunized and followed after therapy (30 successful and 30 unsuccessful) and their husbands formed the cases of this study. In addition, one hundred healthy women were considered as the controls. HLA-DRB1 genotypes of all the cases and controls were checked by PCR-SSP method. <span><br/><b>Results</b>:</span> HLA typing indicated that the prevalence of HLA-DRB1 sharing (defined as at least one allele sharing) between the couples with unsuccessful outcomes was significantly higher compared to those with successful outcomes (63.3% vs. 23.3%, p<0.004). Moreover, HLA DRB1*07:01 allelic group was significantly more frequent in the patients with unsuccessful outcome compared to the controls (18.3% vs. 8%, p<0.04). <br/><b>Conclusion</b>: <span>Our results confirmed the role of HLA sharing in RPL and revealed that</span> HLA-DRB1 typing may be a valuable prognostic factor for the leukocyte therapy outcome.

<b>Background</b>: <span>Pediatric bronchial asthma is associated with considerable morbidity. The</span> study was carried out to examine the association of Human Leukocyte Antigen (HLA)- Class II with the disease as we found no similar study on Asian Indian population. <br/><b>Objective</b>: <span>To define the HLA-Class II antigens in Asian Indian pediatric patients with</span> asthma. <span><br/><b>Methods</b>: </span><span>A total of 103 children with asthma and 152 controls were analysed</span> for HLA Class II (DRB1, DQB1and DPB1) by PCR-SSP (Sequence Specific Primers) method. Total serum IgE levels were determined by ELISA assay. <span><br/><b>Results</b>: </span><span>A positive</span> family history was recorded in 59 patients <span>(</span><span>57%) and 13 (8.5%) of healthy controls.</span> Serum IgE levels were more than normal range in 72% of the patients and 33% of healthy subjects with mean values of 4877 and 627 IU/ml, respectively. DRB1*04 and DQB1*03 showed significant positive relations while DRB1*15 showed a negative association with asthma. DQB1*02 was more common in healthy individuals but was not statistically significant. <span><br/><b>Conclusions</b>: </span><span>A positive association of the DR4/DQB1*03</span> and a negative association of DRB1*15 was seen with extrinsic bronchial asthma. However, more studies are required on larger populations to confirm the association of HLA Class II alleles in Indians before a particular allele can be labeled as being protective or causative for asthma.

<b>Background</b>: <span lang="KO">Interleukin-17 (IL-17), as a potent proinflammatory cytokine, has a</span> critical role in post liver transplant outcomes. However, there is not much information about the effects of IL-17 cytokine on acute liver rejection. <span><br/><b>Objective</b>: </span><span lang="KO">To evaluate the</span> role of IL-17 in post-liver transplant acute rejection. <span><br/><b>Methods</b>: </span><span lang="KO">Ninety seven adult liver</span> transplant patients who enrolled in this cross sectional study were divided into Non- Acute Rejected (Non-AR) and Acute Rejected (AR) patient groups. Three blood samples were collected from each patient in days 1, 4 and 7 post liver transplantation. The IL-17 mRNA levels were evaluated using an in-house real time PCR protocol. IL- 17 protein levels were also analyzed in Non-AR, AR and also control groups using ELISA method. <span><br/><b>Results</b>: </span><span lang="KO">The IL-17 mRNA expression level continuously increased in</span> AR patients in all days of follow-up post liver transplantation. IL-17 expression was, however, down regulated after day 4 post-transplant follow-up in Non-AR patients. Both IL-17 mRNA expression and protein levels were also significantly increased in AR patients compared with Non-AR ones. <span><br/><b>Conclusion</b>: </span><span lang="KO">Based on these findings,</span> significant increase of IL-17 mRNA and protein levels in AR patients highlights the important role of IL-17 in acute liver rejection.

<b>Background</b>: <span>Primary antibody deficiency, the most common primary</span> immunodeficiency disorder, represents a heterogeneous spectrum of conditions caused by a defect in any critical stage of B cell development and is characterized by impaired production of normal amounts of antigen-specific antibodies. <span><br/><b>Objective</b>: </span><span>This</span> retrospective study aimed at description and analysis of demographic, clinical, immunological features and complications of subjects diagnosed with primary antibody deficiency at a referral center in Jordan. <span><br/><b>Methods</b>: </span><span>The medical records of pediatric</span> patients who were diagnosed as primary antibody deficiency (PAD) during the period from January 2006 to June 2013 were reviewed. Patients were diagnosed as PADs based on the Pan-American Group for Immunodeficiency (PAGID) and the European Society for Immunodeficiency (ESID) diagnostic criteria. <span><br/><b>Results</b>: </span><span>A total number of 53</span> patients with PAD were identified; 37(70%) males and 16(30%) females, 16(30%) patients with congenital agammaglobulinemia, 16(30%) patients with common variable immunodeficiency, 4(7.5%) patients with IgG subclass deficiency, 10(19%) cases with transient hypogammaglobulinemia of infancy and 7(13.5%) patients as undefined PAD. The most common infection among patients was pneumonia (62%); followed by suppurative otitis media in 49% of patients. Cytopenia was the most noted autoimmune association and was found at prevalence of 22 %, other autoimmune associations (17%) including inflammatory arthritis, discoid lupus, inflammatory bowel disease, vasculitis and celiac disease. The prevalence of long-term complications was 58%, the most frequent ones were; stunted growth in 13%, bronchiectasis and lymphoproliferation in 11% for each. <span><br/><b>Conclusions</b>: </span><span>Our results indicated that congenital agammaglobulinemia</span> and common variable immunodeficiency are the most frequent primary antibody deficiency in our patients. The awareness of families, general population as well as primary health physicians is crucial in the establishment of early diagnosis and prompt commencement of appropriate therapy for PADs.

X-linked agamaglobulinemia (XLA) or Bruton’s disease is a genetic disease resulting from a mutation in the Bruton’s tyrosine kinase (Btk) gene. This mutation leads to B cell arrest during differentiation (1). This disease was first described by Ogden Bruton in 1952 (2). Approximately 85% of the affected subjects are male (3). This disorder is inherited as an X-linked recessive trait. Carrier females have no symptoms but have a 50% chance for transmission of the disorder to each of their sons. It is now possible to determine if the fetus of a carrier mother has XLA (4). The prevalence of the disease ranges from 1 in 10,000 to 1 in 50,000 (1). Half of the affected individuals are diagnosed during the first year of life and more than 90% of them are diagnosed up to fifth year (3). Diagnosis of the disease is suggested by lymphoid hypoplasia (minimal or no tonsillar tissue and no palpable lymph node) and total immunoglobulins level less than 100 mg/dl. Isohemagglutinins and antibodies to antigens given during routine immunization are abnormally low in this disorder as well. Flow cytometry is an important test for this diagnosis (5). Patients with XLA are protected for the first few months of life by maternal antibody and therefore do not typically present clinically with infection until after 6 months of age, when the maternally-derived antibody level decreases significantly. After diagnosis, treatment includes replacement of intravenous immunoglobulin (IVIG), which significantly reduces the risk of infection (6). The most common organisms affecting these patients are <em><span>Haemophilus influenza</span></em><span>, </span><em><span>Streptococcus pneumonia </span></em><span>and</span> Staphylococcus aureus <span>(3).</span> Based on our knowledge, 4 cases of XLA patients with normal IgG levels (above 500 mg/dl) and 5 cases of XLA subjects with near normal IgG levels (400-500 mg/dl) have been reported in the world (7). Here, we report a case of Bruton’s disease as the fifth case with normal serum IgG level.
