Abstract
BACKGROUND Activated phosphoinositide-3-kinase δ syndrome (APDS) is an inborn error of immunity (IEI) with infection susceptibility and immune dysregulation, clinically overlapping with other conditions. Management depends on disease evolution, but predictors of severe disease are lacking. OBJECTIVES This study sought to report the extended spectrum of disease manifestations in APDS1 versus APDS2; compare these to CTLA4 deficiency, NFKB1 deficiency, and STAT3 gain-of-function (GOF) disease; and identify predictors of severity in APDS. METHODS Data was collected from the ESID (European Society for Immunodeficiencies)-APDS registry and was compared with published cohorts of the other IEIs. RESULTS The analysis of 170 patients with APDS outlines high penetrance and early onset of APDS compared to the other IEIs. The large clinical heterogeneity even in individuals with the same PIK3CD variant E1021K illustrates how poorly the genotype predicts the disease phenotype and course. The high clinical overlap between APDS and the other investigated IEIs suggests relevant pathophysiological convergence of the affected pathways. Preferentially affected organ systems indicate specific pathophysiology: bronchiectasis is typical of APDS1; interstitial lung disease and enteropathy are more common in STAT3 GOF and CTLA4 deficiency. Endocrinopathies are most frequent in STAT3 GOF, but growth impairment is also common, particularly in APDS2. Early clinical presentation is a risk factor for severe disease in APDS. CONCLUSIONS APDS illustrates how a single genetic variant can result in a diverse autoimmune-lymphoproliferative phenotype. Overlap with other IEIs is substantial. Some specific features distinguish APDS1 from APDS2. Early onset is a risk factor for severe disease course calling for specific treatment studies in younger patients.

Abstract
Newborn screening (NBS) for severe combined immunodeficiency (SCID) utilizing T-cell receptor excision circles (TRECs) has been implemented in all 50 states as of December 2018 and has been transformative for the clinical care of SCID patients. Though having high sensitivity for SCID, NBS-SCID has low specificity, therefore is able to detect other causes of lymphopenia in newborns including many inborn errors of immunity (IEIs). In a recent study, three of six newborns later diagnosed with Warts, Hypogammaglobulinemia, Infections, and Myelokathexis (WHIM) syndrome were found to have a low TRECs and lymphopenia at birth. This presents an opportunity to increase the detection and diagnosis of WHIM syndrome by NBS-SCID with immunological follow-up along with a combination of flow cytometry for immune cell subsets, absolute neutrophil count, and genetic testing, extending beyond the conventional bone marrow studies. Coupled with emerging technologies such as next-generation sequencing, transcriptomics and proteomics, dried blood spots used in NBS-SCID will promote earlier detection, diagnosis, and therefore treatment of IEIs such as WHIM syndrome.

Abstract
Severe combined immunodeficiency, SCID, is a pediatric emergency that represents the most critical group of inborn errors of immunity (IEI). Affected infants present with early onset life-threatening infections due to absent or non-functional T cells. Without early diagnosis and curative treatment, most die in early infancy. As most affected infants appear healthy at birth, newborn screening (NBS) is essential to identify and treat patients before the onset of symptoms. Here, we report 47 Brazilian patients investigated between 2009 and 2020 for SCID due to either a positive family history and/or clinical impression and low TRECs. Based on clinical presentation, laboratory finding, and genetic information, 24 patients were diagnosed as typical SCID, 14 as leaky SCID, and 6 as Omenn syndrome; 2 patients had non-SCID IEI, and 1 remained undefined. Disease onset median age was 2 months, but at the time of diagnosis and treatment, median ages were 6.5 and 11.5 months, respectively, revealing considerable delay which affected negatively treatment success. While overall survival was 51.1%, only 66.7% (30/45) lived long enough to undergo hematopoietic stem-cell transplantation, which was successful in 70% of cases. Forty-three of 47 (91.5%) patients underwent genetic testing, with a 65.1% success rate. Even though our patients did not come from the NBS programs, the diagnosis of SCID improved in Brazil during the pilot programs, likely due to improved medical education. However, we estimate that at least 80% of SCID cases are still missed. NBS-SCID started to be universally implemented in the city of São Paulo in May 2021, and it is our hope that other cities will follow, leading to early diagnosis and higher survival of SCID patients in Brazil.

Abstract
INTRODUCTION Endogenous immunoglobulins (Igs) are of fundamental importance in the host defense after microbial infections. However, the therapeutic administration of intravenous IgG (IVIgG) has not yet been shown to improve clinical outcomes in patients suffering from sepsis, and in the case of IgM-containing preparations (IVIgGMA) the positive evidence is only weak. Recently published studies implicate that Ig levels on admission could have an impact on the patient's response to IVIg treatment and on outcomes of critically ill patients. METHODS In this noninterventional study, the serum levels of IgG, IgM, and IgA were determined in 340 medical patients on ICU admission, and clinical outcomes were prospectively recorded (ICU mortality, need for renal replacement therapy (RRT), need for mechanical ventilation, substitution of coagulation factors, and amount of red cell transfusions). Patients were prospectively grouped according to their main reason for ICU admission (sepsis, respiratory failure, cardiovascular diseases, acute renal failure, postoperative condition, state after cardiopulmonal resuscitation, gastrointestinal diseases, and others). RESULTS AND DISCUSSION There was no correlation between the Ig levels on admission and ICU mortality neither in the total cohort of medical ICU patients nor in any prespecified subgroup. However, in a logistic regression model that was adjusted for APACHE II score on admission, an increase in serum IgG was associated with a reduced need for mechanical ventilation in patients suffering from cardiovascular disease. On the other hand, in patients suffering from sepsis, an increased level of IgM was linked to an increased administration of coagulation factors. CONCLUSION Our data do not support the hypothesis that serum levels of immunoglobulins are linked to mortality in medical ICU patients.

Abstract
BACKGROUND Adoptive cell therapy based on mononuclear cells (MNCs) became an important modality of cancer immunotherapy. Data about collection results and donor response of leukapheresis with the Spectra Optia v.5.0 (Terumo BCT) in nonmobilized donors are required. STUDY DESIGN AND METHODS Twelve MNC collections were performed using the Spectra Optia v.5.0 in non-cytokine-stimulated donors. Leukapheresis products and peripheral blood samples from donors were assayed for CD45+, CD34+, CD3+, and CD14+ cells by flow cytometry. Prefreeze and postthaw cell counts, cell viability, and numbers of colony-forming units were assessed in cryobags and compared to data from cryovials. RESULTS Leukapheresis yielded a mean of 5.26×10(9) ±2.2×10(9) CD45+ cells, 1.5×10(9) ±0.77×10(9) CD14+ monocytes, and 2.28×10(9) ±1.2×10(9) CD3+ Tcells by processing 6690±930mL of whole blood. A significant positive correlation between yield of CD3+ Tcells and residual platelets (PLTs) and red blood cells (RBCs) was observed. This did not apply for CD34+ and CD14+ white blood cell subsets. Mean collection efficiencies for CD14+ monocytes and CD3+ Tcells were 61.8±17 and 37.2±18%, respectively. Recovery of CD14+ cells after cryopreservation was 75.2±8.2%, which was significantly lower than recovery of CD45+ cells (81.4±5.5%; p=0.01). CONCLUSION This study of a small cohort demonstrates that the Spectra Optia v.5.0 is capable of collecting low product volumes with satisfactory MNC yields and low residual RBCs and PLTs in non-cytokine-mobilized apheresis. Our data suggest that cryovials can serve as a representative surrogate for the primary product cryobag.

Abstract
Muscular dystrophies (MD) are a clinically and genetically heterogeneous disease group. In the last few years, remarkable progress has been made in understanding the close und various relations between skeletal muscle disease and heart muscle disease. Cardiac involvement has been documented in a number of primary MDs and is even the dominant feature in some of them. The myocardium can be affected in the form of a dilated cardiomyopathy while the conduction system can be affected resulting in arrhythmias and conduction defects. Many patients with MD die because of cardiac complications like sudden cardiac death or congestive heart failure. Detailed clinical data about cardiac involvement are available for Duchenne/Becker MD, Emery-Dreifuss MD, myotonic dystrophy, and the different limb girdle MDs. Cardiac manifestations were also found in congenital MD, central core disease, proximal myotonic myopathy, and nemaline myopathy. No data about cardiac abnormalities are available in oculopharyngeal MD and rippling muscle disease. The heart of patients with primary MD should be carefully investigated because of the life-threatening events caused by cardiac complications. There is a strong need for a close collaboration between neurologists and cardiologists in order to provide optimal disease management for the affected patients.

Abstract
Hypertrophic cardiomyopathy (HCM) is a relatively frequent, genetically determined primary cardiomyopathy, characterized by most often asymmetric hypertrophy of the ventricular septum with or without systolic obstruction of the left ventricular outflow tract. HCM is a genetically heterogeneous disease, with 12 different disease-causing genes beeing indentified to date. Histologically the disease is characterized by hypertophy and disarray of myofibrils as well as by an increase in myocardial fibrosis. Clinically, these changes may lead to palpitations, dyspnoe on exertion, and/or angina pectoris. However, they also lead to an increased propensity to the development of severe ventricular tachyarrhythmias and sudden cardiac death. The incidence of sudden death is significantly increased in HCM, particularly in affected young subjects. Risk stratification in HCM should include a complete clinical-cardiological evaluation that should also consider new diagnostic features, e. g. MR imaging. Major risk factors for sudden cardiac death include a survived cardiac arrest (ventricular fibrillation), non-sustained and sustained ventricular tachycardia, a history of premature familial sudden death, unexplained syncope, an abnormal blood pressure response on exercise, and left ventricular thickness greater than or equal to 3 cm. Ideally, risk stratification should also include genetic testing, since some gene mutations seem to be associated with a higher risk for sudden cardiac death than others. However, genetic testing in HCM in not yet available on a routine basis. The implantation of a cardioverter/defibrillator is first-line therapy in patients with documented ventricular tachycardia/fibrillation or patients who have survived sudden cardiac death. These devices also play an important role in the primary prevention of sudden cardiac death in HCM. Algorithms and scores are available to estimate the risk of sudden death, however, the decision to implant a cardioverter/defibrillator remains an individual decision in every single patient.

Abstract
Cholesterol transport is an essential process in all multicellular organisms. In this study we applied two recently developed approaches to investigate the distribution and molecular mechanisms of cholesterol transport in Caenorhabditis elegans. The distribution of cholesterol in living worms was studied by imaging its fluorescent analog, dehydroergosterol, which we applied to the animals by feeding. Dehydroergosterol accumulates primarily in the pharynx, nerve ring, excretory gland cell, and gut of L1-L3 larvae. Later, the bulk of dehydroergosterol accumulates in oocytes and spermatozoa. Males display exceptionally strong labeling of spermatids, which suggests a possible role for cholesterol in sperm development. In a complementary approach, we used a photoactivatable cholesterol analog to identify cholesterol-binding proteins in C. elegans. Three major and several minor proteins were found specifically cross-linked to photocholesterol after UV irradiation. The major proteins were identified as vitellogenins. rme-2 mutants, which lack the vitellogenin receptor, fail to accumulate dehydroergosterol in oocytes and embryos and instead accumulate dehydroergosterol in the body cavity along with vitellogenin. Thus, uptake of cholesterol by C. elegans oocytes occurs via an endocytotic pathway involving yolk proteins. The pathway is a likely evolutionary ancestor of mammalian cholesterol transport.

Abstract
A cDNA expression library of the larval stage of the cestode worm Echinococcus multilocularis has been established in the phage lambda ZAPII system. By immunoscreening with pooled sera from patients with alveolar echinococcosis an immunoreactive clone, termed pEM13, was isolated. EM13 was expressed using the expression vector pGEX-3X, resulting in the synthesis of a glutathione S-transferase fusion protein. 82% of the sera from 28 patients suffering from E. multilocularis disease had antibodies against EM13, whereas none of the 55 sera obtained from Echinococcus granulosus-infected patients and none of the 15 sera from patients with other helminthic infections reacted with recombinant EM13. By use of a polyclonal rabbit anti-EM13 hyperimmune serum native EM13 protein could be detected only in the protoscolices of E. multilocularis, but not in E. granulosus larvae or hydatid fluid. Immunoelectron microscopy suggested that EM13 is located in the microtriches on the surface of the larvae. In contrast, EM13 mRNA could be detected by Northern blot analysis in both E. multilocularis and E. granulosus larval RNA preparations. Nucleotide and amino acid sequence analysis of a cDNA clone coding for the corresponding antigen of E. granulosus larvae, termed EG13, revealed a 21-bp insertion, a 51-bp deletion and additional 22 nucleotide exchanges resulting in a 96.3% identity at the nucleotide sequence level and a 96.6% identity at the amino acid sequence level to the coding region of the cDNA pEM13. Cross-reactivity of the polyclonal anti-EM13 serum with the recombinant EG13 indicates a posttranscriptional regulation mechanism, resulting in an EG13 negative phenotype in E. granulosus.

Abstract
We studied the expression of lysosomal acid phosphatase (LAP) in mouse by hybridizing Northern blots and tissue sections with the mouse LAP cDNA. Three mRNA species of 2.3, 3.2 and 5.2 KB were identified, which differ in the length of their 3' untranslated region (UTR). The 3.2 KB mRNA is expressed in equal amounts in all tissues and represents the major species in most tissues, whereas the amounts of the 2.3 and 5.2 KB species differ. In situ hybridization of different tissues of adult mice showed a uniform expression of LAP, as expected for a housekeeping gene, except in testis and brain. In testis we found an increase in the LAP mRNA level in spermatocytes. By Northern blot analysis of young mouse testis, this increase could be attributed to late pachytene primary spermatocytes or secondary spermatocytes. In brain tissue the neurons were predominantly labeled, especially the Purkinje and pyramidal cells, whereas glial cells expressed only low amounts of LAP mRNA. Very high LAP expression was also found in the epithelial cells of the choroid plexus. Analysis of LAP expression during mouse embryonic development between Days 9.5 and 17.5 revealed a prominent expression relative to other tissues in the neural tube from Day 9.5 to Day 13.5.

Abstract
The mouse cDNA for lysosomal acid phosphatase was cloned. The deduced amino-acid sequence shows 89 and 96% identity with that of the human and rat enzyme, respectively. Namely all residues known to be important for the structure, catalytic activity and transport of lysosomal acid phosphatase are conserved among the three species.

Abstract
We have isolated a 12-kb genomic clone, which encodes human lysosomal acid phosphatase (LAP), a lysosomal membrane glycoprotein. The human LAP gene has a size of about 9 kb and contains 11 exons (83-947 bp in size). The signal sequence and the first eight amino acids of the LAP protein are encoded by exon 1, the remaining luminal domain by exons 2-10 and the transmembrane and cytoplasmic domains, as well as the 3'-untranslated region, by exon 11. The sequence of the LAP gene confirmed the sequence deduced from the cDNA clone except for nucleotide 1917 in the 3'-untranslated region, where T is changed to C. The 5'-flanking sequence shows promoter activity, as analysed by coupling to bacterial chloramphenicol acetyltransferase. S1-nuclease-protection and primer-extension analysis demonstrate transcription initiation at multiple sites clustering within 23 bp upstream of the translation-initiation codon. Sequences characteristic for promoter regions like TATA-box and CAAT-box sequences could not be identified at typical positions. The absence of these sequences, the high GC content (63.5%), two GC boxes and a region complying with the properties of a CpG island, indicate that LAP is a housekeeping gene.

Abstract
Alignment of the amino-acid sequences of the human lysosomal acid phosphatase (LAP) and human prostatic acid phosphatase (PAP) yielded an extensive homology between the two mature polypeptide chains. In the overlapping part, which extends over the entire PAP sequence and the N-terminal 90% of the LAP sequence, the identity is 49.1%. The LAP has an additional C-terminal sequence, which is encoded by the last exon of the LAP gene. This sequence contains the transmembrane domain of LAP, which is lacking in the secretory PAP. All six cysteine residues as well as 20 out of 27 (LAP) and 26 (PAP) proline residues present in the overlapping part of the proteins are conserved, suggesting that they are involved in stabilization of the tertiary structure of both proteins. Only two out of 8 N-glycosylation sites in LAP and 3 in PAP are conserved, suggesting that the dense N-glycosylation of LAP is related to its function in lysosomes.

Abstract
A 2112-bp cDNA clone (lambda CT29) encoding the entire sequence of the human lysosomal acid phosphatase (EC 3.1.3.2) was isolated from a lambda gt11 human placenta cDNA library. The cDNA hybridized with a 2.3-kb mRNA from human liver and HL-60 promyelocytes. The gene for lysosomal acid phosphatase was localized to human chromosome 11. The cDNA includes a 12-bp 5' non-coding region, an open reading frame of 1269 bp and an 831-bp 3' non-coding region with a putative polyadenylation signal 25 bp upstream of a 3' poly(A) tract. The deduced amino acid sequence reveals a putative signal sequence of 30 amino acids followed by a sequence of 393 amino acids that contains eight potential glycosylation sites and a hydrophobic region, which could function as a transmembrane domain. A 60% homology between the known 23 N-terminal amino acid residues of human prostatic acid phosphatase and the N-terminal sequence of lysosomal acid phosphatase suggests an evolutionary link between these two phosphatases. Insertion of the cDNA into the expression vector pSVL yielded a construct that encoded enzymatically active acid phosphatase in transfected monkey COS cells.
