Abstract
BACKGROUND Allogenic hematopoietic stem cell transplantation (HSCT) and gene therapy (GT) are potentially curative treatments for severe combined immunodeficiency (SCID). Late-onset posttreatment manifestations (such as persistent hepatitis) are not uncommon. OBJECTIVE We sought to characterize the prevalence and pathophysiology of persistent hepatitis in transplanted SCID patients (SCIDH+) and to evaluate risk factors and treatments. METHODS We used various techniques (including pathology assessments, metagenomics, single-cell transcriptomics, and cytometry by time of flight) to perform an in-depth study of different tissues from patients in the SCIDH+ group and corresponding asymptomatic similarly transplanted SCID patients without hepatitis (SCIDH-). RESULTS Eleven patients developed persistent hepatitis (median of 6 years after HSCT or GT). This condition was associated with the chronic detection of enteric viruses (human Aichi virus, norovirus, and sapovirus) in liver and/or stools, which were not found in stools from the SCIDH- group (n = 12). Multiomics analysis identified an expansion of effector memory CD8+ T cells with high type I and II interferon signatures. Hepatitis was associated with absence of myeloablation during conditioning, split chimerism, and defective B-cell function, representing 25% of the 44 patients with SCID having these characteristics. Partially myeloablative retransplantation or GT of patients with this condition (which we have named as "enteric virus infection associated with hepatitis") led to the reconstitution of T- and B-cell immunity and remission of hepatitis in 5 patients, concomitantly with viral clearance. CONCLUSIONS Enteric virus infection associated with hepatitis is related to chronic enteric viral infection and immune dysregulation and is an important risk for transplanted SCID patients with defective B-cell function.

Abstract
Recessive or dominant inborn errors of type I interferon (IFN) immunity can underlie critical COVID-19 pneumonia in unvaccinated adults. The risk of COVID-19 pneumonia in unvaccinated children, which is much lower than in unvaccinated adults, remains unexplained. In an international cohort of 112 children (<16 yr old) hospitalized for COVID-19 pneumonia, we report 12 children (10.7%) aged 1.5-13 yr with critical (7 children), severe (3), and moderate (2) pneumonia and 4 of the 15 known clinically recessive and biochemically complete inborn errors of type I IFN immunity: X-linked recessive TLR7 deficiency (7 children) and autosomal recessive IFNAR1 (1), STAT2 (1), or TYK2 (3) deficiencies. Fibroblasts deficient for IFNAR1, STAT2, or TYK2 are highly vulnerable to SARS-CoV-2. These 15 deficiencies were not found in 1,224 children and adults with benign SARS-CoV-2 infection without pneumonia (P = 1.2 × 10-11) and with overlapping age, sex, consanguinity, and ethnicity characteristics. Recessive complete deficiencies of type I IFN immunity may underlie ∼10% of hospitalizations for COVID-19 pneumonia in children.

Abstract
During the past 50 years, the mortality due to childhood cancers decreased dramatically thanks to improvements in supportive care and the use of multimodal approaches. In this context, the long-term follow up after childhood cancer has become a main concern for pediatric oncologists. The SALTO programme was developed in 2012 at the CHR Citadelle in Liège in order to organize a multidisciplinary long-term follow-up for the patients previously treated in our department for a childhood cancer. The aim of the present study was to review, for the most frequent childhood cancers, the long-term sequellae and the second cancers developed by the patients participating to the SALTO programme in order to define the follow-up needed. Our data confirm the importance of a multidisciplinary long-term follow-up, based on the treatments received and following international guidelines.

Abstract
Sickle cell disease and systemic lupus erythematosus (SLE) are two distinct chronic conditions sharing many clinical manifestations. Coexisting of these two diseases is rare, but it is important to make the diagnosis of SLE in sickle cell patients to initiate appropriate treatment and limit the risk of complications. High titers of autoantibodies have been reported in sickle cell patients as well as a higher risk of immune deficiency. These patients present a defective activation of the alternative pathway of the complement that increases the risk of infection with encapsulated bacteria and a difficulty in eliminating antigenes that could predispose to autoimmune diseases. We report three case of children with sickle cell disease. They developed symptoms initially attributed to sickle cell disease, but after investigations revealed an underlying SLE.

Abstract
BACKGROUND Recent findings strongly support hematopoietic stem cell transplantation (HSCT) in patients with severe presentation of LPS-responsive beige-like anchor protein (LRBA) deficiency, but long-term follow-up and survival data beyond previous patient reports or meta-reviews are scarce for those patients who do not receive a transplant. OBJECTIVE This international retrospective study was conducted to elucidate the longitudinal clinical course of patients with LRBA deficiency who do and do not receive a transplant. METHOD We assessed disease burden and treatment responses with a specially developed immune deficiency and dysregulation activity score, reflecting the sum and severity of organ involvement and infections, days of hospitalization, supportive care requirements, and performance indices. RESULTS Of 76 patients with LRBA deficiency from 29 centers (median follow-up, 10 years; range, 1-52), 24 underwent HSCT from 2005 to 2019. The overall survival rate after HSCT (median follow-up, 20 months) was 70.8% (17 of 24 patients); all deaths were due to nonspecific, early, transplant-related mortality. Currently, 82.7% of patients who did not receive a transplant (43 of 52; age range, 3-69 years) are alive. Of 17 HSCT survivors, 7 are in complete remission and 5 are in good partial remission without treatment (together, 12 of 17 [70.6%]). In contrast, only 5 of 43 patients who did not receive a transplant (11.6%) are without immunosuppression. Immune deficiency and dysregulation activity scores were significantly lower in patients who survived HSCT than in those receiving conventional treatment (P = .005) or in patients who received abatacept or sirolimus as compared with other therapies, and in patients with residual LRBA expression. Higher disease burden, longer duration before HSCT, and lung involvement were associated with poor outcome. CONCLUSION The lifelong disease activity, implying a need for immunosuppression and risk of malignancy, must be weighed against the risks of HSCT.

Abstract
DOCK2 is a guanine-nucleotide-exchange factor for Rac proteins. Activated Rac serves various cellular functions including the reorganization of the actin cytoskeleton in lymphocytes and neutrophils and production of reactive oxygen species in neutrophils. Since 2015, six unrelated patients with combined immunodeficiency and early-onset severe viral infections caused by bi-allelic loss-of-function mutations in DOCK2 have been described. Until now, the function of phagocytes, specifically neutrophils, has not been assessed in human DOCK2 deficiency. Here, we describe a new kindred with four affected siblings harboring a homozygous splice-site mutation (c.2704-2 A > C) in DOCK2. The mutation results in alternative splicing and a complete loss of DOCK2 protein expression. The patients presented with leaky severe combined immunodeficiency or Omenn syndrome. The novel mutation affects EBV-B cell migration and results in NK cell dysfunction similar to previous observations. Moreover, both cytoskeletal rearrangement and reactive oxygen species production are partially impaired in DOCK2-deficient neutrophils.

Abstract
Cancer is the second leading cause of death among children aged 5 to 14, after accidents. We conducted a study on the epidemiology of childhood cancer in the university pediatric oncology department of the CHU-CHR in Liège, Belgium. We studied a cohort of 662 patients between the ages of 0 and 17 whose malignancy diagnosis was made between 1985 and 2016. The analyzes were performed retrospectively using medical files. The number of new cases, the proportion of different cancers, sex ratio, age at diagnosis and survival at 5 and 10 years were the epidemiological factors studied.We have been able to show an increase in the number of new diagnoses per year. More than 40 % of childhood cancers occur before the age of five. The most common neoplasias are leukemias, tumors of the central nervous system and lymphomas. This distribution is influenced by age. All malignant tumours combined, we observed a slightly larger proportion of affected boys than girls. Overall survival at 5 years reaches 80.2 %. However, it varies according to the type of tumour from 59.3 % for malignant soft tissue tumors up to 100 % for hepatoblastomas.

Abstract
Many patients with primary immunodeficiency (PID) who have antibody deficiency develop progressive lung disease due to underlying subclinical infection and inflammation. To understand how these patients are monitored we conducted a retrospective survey based on patient records of 13 PID centres across Europe, regarding the care of 1061 adult and 178 paediatric patients with PID on immunoglobulin (Ig) G replacement. The most common diagnosis was common variable immunodeficiency in adults (75%) and hypogammaglobulinaemia in children (39%). The frequency of clinic visits varied both within and between centres: every 1-12 months for adult patients and every 3-6 months for paediatric patients. Patients diagnosed with lung diseases were more likely to receive pharmaceutical therapies and received a wider range of therapies than patients without lung disease. Variation existed between centres in the frequency with which some clinical and laboratory monitoring tests are performed, including exercise tests, laboratory testing for IgG subclass levels and specific antibodies, and lung function tests such as spirometry. Some tests were carried out more frequently in adults than in children, probably due to difficulties conducting these tests in younger children. The percentage of patients seen regularly by a chest physician, or who had microbiology tests performed following chest and sinus exacerbations, also varied widely between centres. Our survey revealed a great deal of variation across Europe in how frequently patients with PID visit the clinic and how frequently some monitoring tests are carried out. These results highlight the urgent need for consensus guidelines on how to monitor lung complications in PID patients.

Increased colony-forming unit-granulocyte-macrophage was found in the peripheral blood, mimicking granulocyte-macrophage colony-stimulating factor hypersensitivity. These findings fulfilled the diagnosis criteria for juvenile myelomonocytic leukemia (JMML), but no mutations in the CBL, NRAS, KRAS, or PTPN11 genes were detected. In addition to these findings severe hypogammaglobulinemia and elevated alkaline phosphatase were present. Bone X-ray showed dense and radiopaque bones with a bone-in-bone appearance characteristic of infantile malignant osteopetrosis (IMO). Genetic mutation in T-cell, immune regulator 1 (TCIRG1) was identified, confirming the diagnosis of IMO. Careful differential diagnosis including osteopetrosis, is therefore recommended in patients with clinical features and hematologic findings consistent with JMML.

Abstract
OBJECTIVES Clinical data are lacking on optimal levels of specific antipneumococcal antibodies (PnPsAbs) in patients with primary immunodeficiency (PID) receiving intravenous immunoglobulin (IVIG) replacement. Objectives were to conduct a prospective multicenter study providing data on total immunoglobulin G (IgG) and peak/trough levels of PnPsAbs specifically targeting the 16 most prevalent pneumococcal serotypes in IVIG-treated children with PID; to compare trough PnPsAb levels with those measured in healthy adults and the IVIG product; and to evaluate PnPsAb protection correlates with thresholds based on World Health Organization. METHODS Patients received 7 consecutive IVIG infusions. Total IgG and PnPsAb levels were determined on plasma samples obtained before and after infusion. RESULTS Twenty-two children with PID were treated with IVIG (mean weekly dose: 0.10 g/kg). The mean trough and peak levels of total IgG were 7.77 and 13.93 g/L, respectively. Trough and peak geometric mean concentrations and distribution curves differed between serotypes and showed wide dispersion (0.17-7.96 µg/mL). In patients (89%-100%), antibodies against most serotypes reached trough levels ≥ 0.2 µg/mL, a threshold considered protective against invasive pneumococcal infection. For several serotypes, trough levels reached ≥ 1.0 to 1.3 µg/mL, the level found in adults. Trough geometric mean concentrations correlated well with the PnPsAb contents of the IVIG product. CONCLUSIONS In IVIG-treated children with PID, protective PnPsAb levels for most pathogenic serotypes were obtained. A correlation was observed between PnPsAb levels in patients and in the IVIG product. This offers the potential to improve infection prevention by adapting the IVIG product and dose according to epidemiology.

Abstract
OBJECTIVE The goal of this study was to describe the spectrum of clinical signs of mevalonate kinase deficiency (MKD). METHODS This was a retrospective French and Belgian study of patients identified on the basis of MKD gene mutations. RESULTS Fifty patients from 38 different families were identified, including 1 asymptomatic patient. Symptoms began during the first 6 months of life in 30 patients (60%) and before the age of 5 years in 46 patients (92%). Symptoms consisted of febrile diarrhea and/or rash in 23 of 35 patients (66%). Febrile attacks were mostly associated with lymphadenopathy (71%), diarrhea (69%), joint pain (67%), skin lesions (67%), abdominal pain (63%), and splenomegaly (63%). In addition to febrile attacks, 27 patients presented with inflammatory bowel disease, erosive polyarthritis, Sjögren syndrome, and other chronic neurologic, renal, pulmonary, endocrine, cutaneous, hematologic, or ocular symptoms. Recurrent and/or severe infections were observed in 13 patients, hypogammaglobulinemia in 3 patients, and renal angiomyolipoma in 3 patients. Twenty-nine genomic mutations were identified; the p.Val377Ile mutation was the most frequently found (29 of 38 families). Three patients died of causes related to MKD. The disease remained highly active in 17 of the 31 surviving symptomatic patients followed up for >5 years, whereas disease activity decreased over time in the other 14 patients. Interleukin 1 antagonists were the most effective biological agents tested, leading to complete or partial remission in 9 of 11 patients. CONCLUSION MKD is not only an autoinflammatory syndrome but also a multisystemic inflammatory disorder, a possible immunodeficiency disorder, and a condition that predisposes patients to the development of renal angiomyolipoma.

Abstract
In order to illustrate epidemiologic features and survival rate, 31 Wilm's tumours treated in our institution have been retrospectively studied. The mean age at diagnosis in our series was surprisingly higher than usually described: 25% of the patients were older than 8 years. Moreover, a mesoblastic nephroma congenital kidney tumour--appeared in a 10 month old girl. Symptoms were usually abdominal mass or gross hematuria. Young children are often brought to medical attention because of abdominal swelling: a large flank mass was palpable in all children under 5 years. Our study shows that preoperative chemotherapy results in a less intensive treatment regimen conducting probably to less sequellae. Event free survival and overall survival were respectively 87% and 94% at 10 years after diagnosis. Renal insufficiency was the most important side effect: 2 children required renal transplantation.

Abstract
Activation-induced cell death (AICD) is involved in peripheral tolerance by controlling the expansion of repeatedly stimulated T cells via an apoptotic Fas (CD95; APO-1)-dependent pathway. The TNFRSF-6 gene encoding Fas is mutated in children suffering from autoimmune lymphoproliferative syndrome (ALPS), which is characterized by lymphoproliferation and autoimmunity. We examined AICD in Fas-deficient T cells from ALPS patients. We showed that primary activated Fas-deficient T cells die by apoptosis after repeated T cell antigen receptor (TCR) stimulation despite resistance to Fas-mediated cell death. This Fas-independent AICD was found to be mediated through a cytotoxic granules-dependent pathway. Cytotoxic granules-mediated AICD was also detected in normal T lymphocytes though to a lesser extent. As expected, the cytotoxic granules-dependent AICD was abolished in T cells from Rab27a- or perforin-deficient patients who exhibited defective granules-dependent cytotoxicity. Supporting an in vivo relevance of the cytotoxic granules-dependent AICD in ALPS patients, we detected an increased number of circulating T lymphocytes expressing granzymes A and B. Altogether, these data indicated that the cytotoxic granules-dependent cell death in ALPS may compensate for Fas deficiency in T lymphocytes. Furthermore, they identified a novel AICD pathway as a unique alternative to Fas apoptosis in human peripheral T lymphocytes.

Abstract
The recent demonstration that bone sialoprotein (BSP) is expressed in osteotropic cancers suggests that this bone matrix protein might be implicated in the preferential seed and growth of metastatic cells in bone. High expression of BSP in breast and prostate primary carcinomas is associated with progression and bone metastases development. The exact mechanisms by which BSP may favor bone metastases formation are not clearly established yet. Although BSP expression has been detected in breast, prostate, lung, thyroid, and neuroblastoma primary tumors, no information regarding its expression in metastases is available to date. In this study, we have examined BSP expression in 15 bone and 39 visceral metastatic lesions harvested from 8 breast cancer patients and 7 prostate cancer patients who died of disseminated disease. We were able to retrieve the primary lesions from 5 of the 8 breast cancer patients as well as from all 7 prostate cancer patients. All the primary breast tumor patients and 5 of the 7 primary prostate cancer patients expressed a detectable level of BSP. Bone metastases from all 8 breast cancer patients and from 5 out of 7 prostate cancer patients exhibited detectable levels of the protein. Metastatic cells in close contact with bone trabeculae usually were highly positive for BSP. BSP also was detected in secondary lesions developed at visceral sites including liver, thyroid, lung, and adrenal glands. However, BSP expression was significantly lower in visceral metastases than in skeletal ones (Mann-Whitney test, p < 0.05). Our data represent the first demonstration of an increased expression of BSP in bone metastases compared with nonskeletal metastases in human breast and prostate cancers and add weight to the body of evidence attributing a significant role to this protein in the genesis of bone metastases.
