Full textObjective: To perform the molecular characterization of C1q, C4 and C2 genes in patients with Juvenile Systemic Lupus Erythematosus (JSLE). Methods: Four patients with JSLE and C1q, C4 and/or C2 deficiencies were chosen. Patient P1 had undetectable C1q serum level and normal levels of C3 and C4; Patient P2 had decreased levels of C2 and C4 serum while P3 had decreased C2 with normal C3 and C4 levels. Lastly P4 had repeated decreased C4 and normal C1q, C2 and C3 serum levels. C1q and C2 genes were sequenced. Peripheral mononuclear cells from patients P1, P3 and P4 and from three healthy individuals were both cultivated and stimulated with interferon gamma and a quantitative PCR (qRT-PCR) was also performed to verify mRNA expression. Results: C1q molecular characterization for P1 revealed heterozygous silent mutations in A chain (c.276 A>G Gly) and in C chain (c.126 C>T Pro). Additionally, in B chain two homozygous single-base exchanges were detected in the 5´UTR (c. -159 T>G) and 3\'UTR region (c*78 A>G). The qRTPCR revealed that C1qA gene mRNA expression without stimulation was decreased 1.3 times and with interferon gamma was 1.6 times more expressed compared with controls samples. C1qB gene expression without stimulation was 2.2 times decreased and when stimulated was 1.5 times more expressed. Controls did not expressed C1qC gene and patient P1 had low expression both with and without stimulation. P2 had 2 copies of C4A and 1 copy of C4B. C2 gene sequencing (P2 and P3) showed 100% match with referenced sequence, with exception to 28bp deletion at the exon 6 (heterozygous C2 deficiency type I). C2 mRNA expression from P3 without stimulation was 23 times decreased and with interferon was 4.2 times decreased compared with controls. P4 had 2 copies of C4A and 3 copies of C4B. The qRT-PCR were performed only in C4B gene showed without stimulation a 14 times decreased expression and with interferon stimulation the expression were similar to controls. Conclusions: The two homozygous single-base exchanges in 5\'UTR and 3\'UTR that correspond to the promoter region and stabilization mRNA region in B chain of C1q gene, may have modified mRNA transcription as its expression was decreased without stimulation. Further analysis is necessary to relate C1q gene variations and undetectable serum C1q. In addition, heterozygous C2 deficiency type I may lead to reduced mRNA expression and may be present in JSLE patients with detectable C2 levels. Finally, the decreased C4B gene expression showed that serum dosage and gene copy number may not be sufficient to assess C4 deficiency

Full textActivation of complement and contact systems results in the formation of vasoactive peptides such as bradykinin and anafilatoxinas. The C1 esterase inhibitor (C1-INH) is the main regulator of these two systems and the deficiency of this protein results in hereditary angioedema (HAE). It is a rare disease of autosomal dominant inheritance, characterized by deficiency of C1-INH, which is due to mutations in its structural gene, leading with severe episodes of edema in subcutaneous tissue, gastrointestinal and respiratory tract, potentially fatal. There are two phenotypic variants: HAE type I, with reduced plasma antigen levels and HAE type II with normal or low levels of C1-INH and dysfunctional activity. Several mutations have been described in the gene of the C1 esterase inhibitor (SERPING1), however, no studies to assess the relevance of this disease and the gene mutations in our population. The purpose of this study was to evaluate the molecular changes in patients with HAE, correlating it with clinical and laboratory manifestations. Samples of plasma, serum and DNA from fifteen patients from the same family were collected. CH50 hemolytic assay for assessing the integrity of the classical pathway of the complement system and quantitative evaluation of C1-INH and C4 by nephelometry tests were performed to confirm the diagnosis of disease. The functional activity of the protein was assessed by colorimetric assay and the possible relationship between mutations in the protein and the phenotype of the disease was assessed by polymerase chain reaction (PCR) and sequencing of genomic DNA. Hemolytic activity of complement and the total dosage of C3 were normal in patients and controls. Levels of antigenic activity of C1-INH and C4 were shown to be less valued in most (13/15). Functional evaluation found low activity (<50%) of normal (70% - 130%) in all patients examined. The distribution of mutations among the 8 exons of the gene for C1-INH concentrate in the exons 4 (g.4706-88A> G) and 7 (g.14145 +20 A> G) and 8 (Val480Met). Two of these mutations have not been described yet, which contributes to understanding the function of serpins and also helps to define more fully the biological role of the C1 inhibitor

Full textObjectives. The objectives of this study were: to establish the frequency of primary immunoglobulin and Complement deficiency in Juvenile SLE (JSLE); to evaluate possible associations between the presence of primary immunodeficiency and demographic data, occurrence of infections, JSLE clinical manifestations, disease activity, cumulative damage and therapy; and to determine the frequency of anti-C1q antibody, establishing its sensitivity, specificity and predictive values for JSLE diagnosis. Methods. Seventy-two JSLE patients were analyzed for serum levels of immunoglobulin classes (IgG, IgA, IgM e IgE) and IgG subclasses and early components of the classical Complement pathway (C1q, C1r, C1s, C4, C2, C3). Sixty-seven patients and 26 healthy controls were evaluated for the presence of anti-C1q antibody. C4 gene copy number was determined by real time PCR (polymerase chain reaction) in C4 deficient patients. Seventy patients were analyzed by PCR for the presence of type I C2 deficiency. Results. Evidence of PID was identified in 16 patients (22%): 3 with C2 deficiency (D), 3 with C4D, 2 with C1qD, 4 with IgG2D (<20mg/dL), 3 with IgAD (<7mg/dL), and 3 with IgMD (<35mg/dL); one of these patients presented concomitant IgA, C2 and C4 deficiency. Four out of the 13 boys (30%) and 12 out of 59 girls (20%) had PID diagnosis. SLE features did not differ between patients with and without PID. The median SLICC/ACR-DI was higher among PID subjects (p=0.0033), as was the frequency of SLICC/ACR-DI>1 (p=0.023). Both groups did not differ regarding the occurrence of infections and therapeutic for JSLE. The only 2 cases with age of onset below 2 years presented C1qD and IgMD, respectively. For JSLE diagnosis, the anti-C1q antibodies presented a specificity of 100% (CI 86.7-100%), sensitivity of 19.4% (CI 10.7-30.8%), positive predictive value of 100% (CI 75.3-100%) and negative predictive value of 32,5% (CI 22,4-43,9%). Conclusions. A high frequency of immunoglobulin and Complement deficiency was observed in this JSLE series, suggesting that these defects may contribute to lupus development. Our findings indicate that these two groups of PID should be investigated in early-onset and severe lupus

Full textCryptococcus sp is a fungal pathogen with a worldwide distribution. Although it is ubiquitous in the environment, cryptococcal disease occurs predominantly in immunocompromised hosts and can also occur in apparently immunocompetent individuals. The innate immunity is of special relevance for the antifungal reaction, as it allows an immediate reaction and recognizes a broad variety of fungal pathogens. The host immune response is a major determinant of the outcome of cryptococcal infection; however, the antibodies response is poorly understood. In addition, most of the studies are experimental and there is restricted knowledge concerning the human immune response. Complement system has soluble factors, restrictive regulator proteins and cellular receptors involved in defense mechanism. Glucuroxylomannan (GXM) monoclonal antibodies (MAbs) have numerous biological activities: a) opsonization for phagocytosis, b) activation of the classical complement pathway leading to early deposition of C3 fragments on the yeast, c) suppression overall accumulation of C3 via the alternative pathway; d) clearance facilitation of GXM from serum in vivo, leading to increased accumulation of GXM in tissues rich in mononuclear phagocyte system; e) protection in murine models of cryptococcosis and f) facilitation of various aspects of cellular immunity to Cryptococcus sp. The goal of our study was to evaluate if the antibody response to GXM and cell wall proteins regarding specific antibodies as well as complement system in sera of immunocompetent adults with and without neurocryptococcosis. The aim of our research was to evaluate classical and alternative complement system pathway, to quantify mannose-binding lectin (MBL) as well antibody response to GXM and cell wall proteins (AgS) regarding specific antibodies in sera of immunocompetent adults with and without neurocryptococcosis. One hundred and six samples were collected and classified in 3 groups: group 1- 21 individuals with neurocryptococcosis and low exposure to the yeast; group 2- was composed by 23 healthy individuals, chicken farmings from Jurumirim, a town 164 km to São Paulo, and with high exposure to Cryptoccocus spp and HIV negative. The third group included 60 healthy HIV negative individuals with presumed low exposure to Cryptococcus. Two patients were excluded by report of previous malignancies (timoma and pulmonary cancer). The complement system was evaluated by hemolytic assay and ELISA to MBL. CH 50 and AP 50 values were within the normal range in 17/21; 13/23; 59/60 patients in groups 1, 2 and 3 respectivelly. Mean CH 50 values were significantly different among the three groups (P < 0,0001). Group 2 showed significantly reduced levels in comparison with groups 1 and 3. AP 50 values were within the normal range in 11/21; 21/23; 60/60 patients in groups 1, 2 and 3 respectivelly. There was difference in the AP 50 values (P=0,0005) and one no activation of this pathway in group 1. There was significant difference in MBL among the groups (P = 0,0277). GXM antibodies IgG was measured by ELISA and expressed as optical density (OD). GXM- IgG was detected in all the groups with significant difference among them (P = 0,0127). The means of IgG anti-GXM (OD) were: 1.191 (range 0,49 to 1.217) in group 1, 1.572 (range 0,815 to 2.479) in group 2 and 0,965 (range 0,321 to 1.295) in the group 3. Two of the group 2 individuals had low GXM titers (1/256 and 1/32) and no symptoms. Four patients (4/21; 19%) with neurocryptococcosis died and the results showed: normal classical pathway activation, 2/4 had low (12 UI/mL) or undetectable alternative pathway values ; 3/4 had high MBL concentrations and only one had low OD for IgG anti-GXM. In conclusion, our results suggest that constant and high exposure to Cryptococcus sp can prevent the development of cryptococcosis, i.e. constant and intensive fungal exposition induces protective antibodies to clinical disease but not to the infection. In the other side, genetic factors which determine MBL concentrations could influence the susceptibility to neurocryptococcosis. The antibodies contribute to GXM clearance, however, the concentrations did not correlate with the resistance to the disease

Full textBACKGROUND: Advanced liver disease caused by hepatitis C virus (HCV) is the leading indication for liver transplantation worldwide. More than half of patients present disease recurrence up to one year after transplantation. Liver biopsy plays an essential role in disease recurrence diagnosis and consequently in its treatment, and differential diagnosis regarding acute rejection may sometimes be difficult. Tissue marker C4d and quantification of tissue HCV RNA have been proposed as auxiliary methods in this differential diagnosis. OBJECTIVES: Main objective was to evaluate the role of C4d deposition and tissue quantification of HCV RNA in the differential diagnosis between acute rejection and viral recurrence in liver transplant recipients. Secondary objectives were: to evaluate the association between C4d deposition and epidemiological, clinical, laboratorial, and histological features of acute rejection and chronic hepatitis; and to evaluate the association between tissue quantification of HCV RNA and epidemiological, clinical, laboratorial and histological features of chronic hepatitis. METHODS: A retrospective diagnostic study was performed with liver biopsy samples. Specimens were selected based on histological diagnosis, and divided into four groups: acute rejection in patients transplanted for HCV (group I), HCV recurrence without rejection (group II), acute rejection in patients transplanted for conditions other than HCV (group III), and non-transplanted chronic HCV (group IV). Patients charts were reviewed and laboratorial data were collected in order to obtain demographic, clinical and laboratorial data. Samples were stained for C4d with quantitative grading of compartments (portal area, hepatic sinusoids and centrilobular) and were submitted to HCV RNA quantification. The following outcomes were compared among groups: C4d quantitative tissue staining and tissue HCV RNA quantification. RESULTS: Twenty-eight cases were included in group I, 25 cases in group II, 20 cases in group III, and 25 cases in group IV. The main compartment of deposition was portal, with intense staining in group IV, with statistical difference compared to all other groups (p=0,002). Portal C4d presented intense correlation with periportal inflammation. There was no statistical difference in C4d quantification between rejection and recurrence groups among patients transplanted for HCV. Tissue HCV RNA quantification was higher in hepatitis C recurrence samples compared to acute rejection samples (p<0,001), and there was significant correlation with serum HCV RNA quantification and with time of biopsy after transplantation. Area under ROC curve was 0,818 for tissue HCV RNA quantification, and with a cutpoint of 58,15 IU/ml, the test presented sensitivity of 70% for the diagnosis of disease recurrence, specificity of 89%, and positive and negative predictive values of 84% and 78%, respectively. CONCLUSIONS: Although there was no difference in C4d quantification between acute rejection and viral recurrence groups in patients transplanted for HCV, there was intense portal C4d deposition in non-transplanted chronic hepatitis C cases. Correlation was found between portal C4d and periportal inflammation grading. Tissue HCV RNA quantification was statistically higher in disease recurrence group compared to acute rejection, and this test is a potential diagnostic test for this differential diagnosis

Full textMalaria is one of the major causes of disease and death worldwide, mainly of children. It is also the strongest known force for evolutionary selection in the recent history of the human genome. Besides environmental and parasite factors, host genetic factors play a major role in determining both susceptibility to malaria and the course of infection. Innate immune mechanisms directed against Plasmodium parasites both contribute to protection from malaria and modulate adaptive immune responses. The innate immune system recognizes Plasmodium via a limited number of pattern-recognition receptors (PRRs) and initiates a broad spectrum of defense mechanisms that result in the development of inflammation and host resistance to infection. But, the complete control of the infection requires adaptive immune responses; and the innate immune system is also very efficient in instructing the cellular mediators of adaptive immunity to lead a powerful additional strike force against the parasite. Clinical malaria is characterized by high levels of circulating proinflammatory cytokines, which are thought to contribute to the immunopathology of the disease. The balance between pro- and anti-inflammatory responses toward the parasite is considered critical for clinical protection. The innate immune system initiates and thus sets the threshold of immune responses. In this study, we investigated single nucleotide polymorphisms (SNP) in the genes of three PRRs: TLR, MBL and CR1 in Plasmodium-infected individuals living in endemic areas of Brazil. The SNPs TLR1 (I602S), TLR4 (D229G), TLR6 (S249P), TLR9 (T-1237C/ -1486C), MBL [in the coding sequence of exon 1 at codons 52, 54, and 57 (MBL2*A or D, A or B, and A or C, respectively); in the promoter region at position -221 (*X or *Y); and in the untranslated sequence at position +4 (*P or *Q)] and CR-1(C5507G) were determined by PCR-RFLP. We observed associations of the TLR1 I602S, TLR6 S249P and untranslated sequence at position +4 MBL (*Q) variants with clinical manifestations of malaria and of the TLR9 T-1486C, TLR9 T-1237C, MBL2*D and MBL-insufficient diplotype (XA+O/O) with higher parasitemias. No association was observed to the CR-1 C5507G ) and clinical manifestations of malaria or parasitemia. Also, we observed that individuals with MBLsufficient haplotype (YA/YA+YA/XA+YA/O+XA/XA) and not bearing the allele TLR1 I602S had less clinical manifestations of malaria and individuals with MBL-sufficient haplotype and not bearing TLR9 -1486C had lower parasitemias when compared to individuals with MBL-insufficient diplotype and bearing the variant alleles TLR1 I602S and TLR9 -1486C, respectively. Altogether, our data indicate that TLR-9 promoter and MBL-insufficient haplotype (XA+O/O) polymorphisms to some extent may control the level of Plasmodium parasitemia while TLR1 deficiency seems to predispose to mild malaria. Also, they could suggest cooperation among TLR1, TLR9 and MBL in the immune response against malaria. These genetic findings may contribute to the understanding of the pathogenesis of malaria and raise a potentially interesting issue that is worthy of further investigation in other population in order to validate the genetics contribution of these loci to the pathogenesis of malaria

Full textAllograft rejection mediated by cellular or humoral mechanisms represents an important complication after kidney transplantation. Capillary C4d deposition was recognized as a specific and independent prognostic marker of antibody mediated rejection. The gold standard technique for C4d detection is the immunofluorescence in cryostat sections. However, this technique involves some operating and costs limitations, particularly in Brazil. In antibody mediated rejection, the analysis of B lymphocytes and plasma cells is of pathogenetic relevance since these cells are responsible for antibody production. Considering that the involvement of B lymphocytes and plasma cells in the rejection process is not clear, in this study the CD20 and CD138 expression in kidney biopsies will be also analyzed. Therefore, the aim of the present study was to analyze the C4d detection by 4 different techniques and the infiltration of B lymphocytes and plasma cells in renal allograft biopsies, correlating these findings with the capillary C4d deposition. One hundred and seven biopsies of 82 renal transplant patients were analyzed. C4d was evaluated by immunofluorescence (IF) and immunohistochemistry (IHC) techniques in frozen and paraffin sections (obtained from the same patients), whereas B-lymphocytes and plasma cells were evaluated by immunohistochemistry in paraffin sections using specific antibodies anti-B Lymphocytes (CD20) and anti-plasma cells (CD138). Regarding the C4d detection, the techniques with higher concordance rate with frozen-IF, considered the gold standard, were the frozen-IHC technique (85.4% of cases showed coincident results, r=0.72; p<0.0001) and the paraffin-IF technique (73%, r=0.59; p=0.0001), whereas the concordance rate in the paraffin-IHC technique was only 51.4% (r=0.35; p=0.03). The clinical follow up analysis demonstrate that C4d positive group was associated with a poor graft survival at 3 years post-diagnosis (67% vs 96% in C4d negative group; p=0.01). The histological analysis of mature B cells (CD20+) infiltrate showed 2 distinct patterns: scattered cells and clusters. The cluster pattern was associated with poor graft survival at 3 years (61% vs 89% in the CD20 negative group; p=0.03; and 61% vs 87% in the CD20+ scattered pattern group; p=0.03). The plasma cells infiltrate was not associated with a worse clinical transplant outcome. The analysis of the capillary C4d and B lymphocytes correlation demonstrate that the number of CD20+ and CD138+ cells was significantly higher in C4d positive cases (CD20+: 155±53 vs 26±7 cells/mm2, respectively; p=0.001; CD138+: 46±22 vs 4±1 cells/mm2, respectively; p=0.002). This study concluded that C4d capillary and mature B cells (clusters pattern) are associated with worse graft survival. Another important conclusion is a positive association between B lymphocytes (mature B cells and plasma cells) and capillary C4d, suggesting a possible role of these cells, responsible for antibodies production, in the in situ complement system activation. Finally, the frozen-IHC and paraffin-IF techniques may be considered alternative to frozen-IF technique for C4d detection

Full textBACKGROUND: Mannose-binding lectin (MBL) is a protein that recognizes carbohydrates on microbial surface leading to complement activation. This process is mediated by MBL-associated serine proteases, such as MASP-2. MBL/MASP-2 complex is responsible for generating the C3 convertase C4bC2b. Both MBL and MASP-2 levels are genetically determined, and can be influenced by the presence of single nucleotide polymorphisms (SNPs) in the genes encoding for these proteins (namely MBL2 and MASP-2). OBJTECTIVE: to determine MBL and MASP-2 serum levels and the frequencies of MBL2 and MASP-2 gene polymorphisms in a Brazilian population sample. METHODS: 294 blood donor samples [median age = 36.51 ± 10.56 years, range 18-63, 91/294 (31%) females and 203/294 (69%) males] were genotyped for MBL2 exon 1 SNPs: single point mutation in codon 52 (ArgCys), 54 (GlyAsp) and 57 (GlyGlu), and MASP-2 polymorphism Asp371Tyr (D371Y, A>C) (exon 9). A melting temperature assay was used to perform the genotyping of MBL2 SNPs. The combination of variants of MBL2 were grouped together as allele O, wild types were indicated as A. Exon 1 promoters were evaluated by direct genotype sequencing- alleles H/L, X/Y and P/Q (positions -550, -221 and +4, respectively). MASP-2 exon 9 genotyping was performed by using TaqMan pre-developed assay. RESULTS: MBL2: 58.5% A/A, 36.39% A/O, 5.1% O/O; promoters: 13% H/H, 39% H/L, 48% L/L; 2% X/X, 26% X/Y, 72% Y/Y; 52% P/P, 37% P/Q, 11% Q/Q; haplotypes: 15% LXPA, 28% HYPA, 8% LYQO, 12% LYPO, 11% LYPA, 22% LYQA and 4% HYPO. MASP-2: 38.78% A/A, 44.56% A/C and 16.67% C/C. CONCLUSION: The prevalence (5.1%) of O/O genotype of MBL2 exon 1 SNPs in our population is in accordance with Brazilian reports, similar to European (4%) and Japanese (5%); lower than Africans (10-14%). There is a correlation between MBL serum levels and genotyping. Moreover, this is the first report of D371Y MASP-2 polymorphism frequency in a Brazilian population. Our data may contribute to new insights on the role of MBL and MASP-2 in clinical conditions
