Abstract
BACKGROUND Coronavirus Disease 2019 (COVID-19) seems to affect children only marginally, as a result, there is less knowledge of its manifestations in childhood. The purpose of this retrospective cross-sectional study was to investigate the oral and cutaneous manifestations in children affected by COVID-19. MATERIAL AND METHODS All the medical records of children with COVID-19 admitted to the Pediatric Clinic- ASST Spedali Civili of Brescia from March to April 2020 were reviewed. The following data were recorded: age, temperature, clinical presentation, oral mucosa lesions, taste alteration and cutaneous lesions. RESULTS The medical records of twenty-seven pediatric patients (mean age 4,2 years + 1,7) were analyzed. The clinical presentation of the disease mainly included elevated body temperature and cough. The following oral lesions were recorded: oral pseudomembranous candidiasis (7.4 %), geographic tongue (3.7%), coated tongue (7.4 %) and hyperaemic pharynx (37 %). Taste alteration was reported by 3 patients. Six patients presented cutaneous flat papular lesions. CONCLUSIONS As for our paediatric sample, COVID-19 resulted to be associated with non-specific oral and cutaneous manifestations.

Abstract
In the management of adolescents with systemic lupus erythematosus (SLE), sexual activity and prevention of unwanted pregnancies are important topics. Many contraceptive methods are available nowadays. Oral contraceptives (OCs) are the preferred choice among adolescents in general. However, the use of these medications in adolescents with SLE raises serious concerns, particularly the risk of thrombotic events from estrogen exposure and the impact of these medications on lupus activity. In this article, different contraceptive methods available are reviewed and their application in adolescents with SLE is discussed. In conclusion, OCs are the methods of choice in adolescents with stable disease and no antiphospholipid antibodies (aPL) detected. In patients with aPL, fewer options are available, and the selection of the preferred form of contraception should be made on an individual basis. Lupus (2007) 16, 600—605.

Abstract
OBJECTIVE To evaluate genetic, demographic and clinical features in patients with cryopyrin-associated periodic syndrome (CAPS) from the Eurofever Registry, with a focus on genotype-phenotype correlations and predictive disease severity markers. METHODS A web-based registry retrospectively collected data on patients with CAPS. Experts in the disease independently validated all cases. Patients carrying NLRP3 variants and germline-mutation-negative patients were included. RESULTS 136 patients were analysed. The median age at disease onset was 9 months, and the median duration of follow-up was 15 years. Skin rash, musculoskeletal involvement and fever were the most prevalent features. Neurological involvement (including severe complications) was noted in 40% and 12% of the patients, respectively, with ophthalmological involvement in 71%, and neurosensory hearing loss in 42%. 133 patients carried a heterozygous, germline mutation, and 3 patients were mutation-negative (despite complete NLRP3 gene screening). Thirty-one different NLRP3 mutations were recorded; 7 accounted for 78% of the patients, whereas 24 rare variants were found in 27 cases. The latter were significantly associated with early disease onset, neurological complications (including severe complications) and severe musculoskeletal involvement. The T348M variant was associated with early disease onset, chronic course and hearing loss. Neurological involvement was less strongly associated with V198M, E311 K and A439 V alleles. Early onset was predictive of severe neurological complications and hearing loss. CONCLUSIONS Patients carrying rare NLRP3 variants are at risk of severe CAPS; onset before the age of 6 months is associated with more severe neurological involvement and hearing loss. These findings may have an impact on treatment decisions.

Abstract
BACKGROUND Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPS) is a hereditary autoinflammatory syndrome characterized by recurrent episodes of fever and localized inflammation. Clinical presentation can be very variable in terms of duration of fever attacks, periodicity, and accompanying manifestations. One of the most characteristic symptoms is the occurrence of migrating skin rash with myalgia that is sustained by monocytic inflammation. OBSERVATIONS We herein present the case of a family suffering from TRAPS who had been misdiagnosed for a long period of time and whose main symptom was migrating angioedema. Skin biopsy from one of the patients documented a monocytic panniculitis. All the living patients responded dramatically to anakinra treatment. CONCLUSIONS The classic symptom of migratory angioedema with myalgia in TRAPS can be produced by monocytic panniculitis.This manifestation is so characteristic of TRAPS that its occurrence, even in the absence of other manifestations, should prompt genetic analysis. Our patient's condition responded promptly to anakinra treatment.

Abstract
Reactive astrogliosis, a feature of neuro-inflammation is induced by a number of endogenous mediators including cytokines. Despite interleukin-1 beta (IL-1β) stands out as the major inducer of this process, the underlying mechanism and its role on neuronal viability remain elusive. We investigated in human astrocytoma cells and the rat brain striatum, the role of the nuclear factor-kB (NF-kB) intracellular Ca(2+) concentration ([Ca(2+)]i) calmodulin (CaM) and extracellular regulated mitogen-activated protein kinases (ERK1/2) in IL-1β-induced expression of glial fibrillary acidic protein (GFAP) and neuronal apoptosis associated to a brain trauma. Cell data showed that IL-1β (1 ng/ml) increased NF-kB, pERK1/2 and GFAP expression. Nevertheless, further increase in IL-1β levels reversed progressively these responses. Preventing ERK1/2 activation with 1,4-diamino-2,3-dicyano-1,4-bis[2-aminophenylthiol]-butadiene antagonized IL-1β-induced GFAP expression while inhibiting selectively nuclear translocation of NF-kB with caffeic-acid phenethyl-ester down-regulated both ERK1/2 and GFAP expression induced by IL-1β. The GFAP response was also prevented by antagonizing selectively increase in [Ca(2+)]i, CaM activity or inducible nitric oxide synthase expression with respectively ryanodine plus 2-aminoethoxydiphenyl-borate, N-(6-aminohexyl)-5-chloro-1-naphthalensulfonamide hydrochloride and N-[(3-(aminomethyl)-phenyl]methyl]-ethanimidamide dihydrochloride. Data in vivo supported these findings and showed that GFAP expression induced by IL-1β (50 ng/ml) correlated with attenuated glial scar formation and reduced neuronal apoptosis. Our data identified the NF-kB/Ca(2+)-CaM/ERK signaling pathway as a novel in vivo key regulator of IL-1β-induced astrogliosis which may represent a potential target in neurodegeneration.

Abstract
Aicardi-Goutières syndrome (AGS) is a rare genetic encephalopathy characterized by neurological and extraneurological involvement. A clinical overlap between AGS and systemic lupus erythematosus (SLE) has been reported. We describe an AGS patient who developed autoimmune manifestations: thyroiditis, cANCA positivity, antiphospholipid antibodies and cerebral ischemia. This first description of antiphospholipid syndrome in a TREX1-mutated patient further expands the clinical spectrum of AGS. Although the clinical overlap with SLE may indicate common pathogenic mechanisms, the autoimmune manifestations in AGS are so extensive that we suggest they should be considered a clinical feature of the disease, rather than a sign of coexistent SLE.

Abstract
OBJECTIVE Anti-β2 GPI are a formal laboratory criterion for the antiphospholipid syndrome (APS). They were demonstrated to be a risk factor for thrombosis and fetal losses but can also be detected in patients with systemic autoimmune disease (SAD), in healthy adults individuals and pre-school children. It has been suggested that different subpopulations of anti-β2GPI may carry different pathogenetic potential: autoantibodies against Domain1 seem to be associated with thrombosis; autoantibodies against Domain4/5 have been identified in patients with non-thrombotic conditions. METHODS We studied 48 patients with SAD (32 systemic lupus erythematosus, 16 undifferentiated connettive tissue disease), 64 patients with APS, 57 one-year-old healthy children born to mother with SAD, 33 children with atopic dermatitis. All subjects were IgG anti-β2 GPI positive. The specificity of anti-β2 GPI was investigated using ELISA research products containing recombinant β2 GPI D1 and D4/5 antigens. Cut-off values are calculated as 95th percentile on 100 NHD. IgG anti-β2 GPI were tested at a validated home-made ELISA routinely performed in our laboratory. No thrombotic events were recordered in patients with SAD and in both groups of children. RESULTS Patients with SAD and APS showed prevalent reactivity for D1 while children in both groups preferentially recognize D4/5. CONCLUSIONS IgG anti-β2 GPI against D1 seem to cluster in patients with systemic autoimmune conditions. Their pathogenic potential in determine APS manifestations may be mitigated by adequate prophylaxis.

Abstract
Objective To analyze the long-term impact of the R92Q mutation of TNFRSF1A in children with periodic fever, in comparison with children with tumor necrosis factor receptor–associated periodic syndrome (TRAPS) with TNFRSF1A structural mutations and children with periodic fever of unknown origin fulfilling the criteria for periodic fever, aphthosis, pharyngitis, and adenitis syndrome (PFAPA). Methods The extracellular region of TNFRSF1A was analyzed in 720 consecutive children with periodic fever, using denaturing high-performance liquid chromatography and DNA sequencing. Followup data on 11 pediatric patients with TNFRSF1A structural mutations (cysteine or T50M), 23 pediatric patients with an R92Q substitution, and 64 pediatric patients with PFAPA were collected during routine clinic visits. The 50-item Child Health Questionnaire was used to assess health-related quality of life (HRQOL). Results The frequency of typical TRAPS-related clinical manifestations was significantly lower and the impact of the disease on HRQOL was significantly reduced in patients with the R92Q mutation compared with TRAPS patients carrying structural mutations of TNFRSF1A. Followup data on 11 TRAPS patients with TNFRSF1A structural mutations (mean followup 7.9 years), 16 patients with theR92Q substitution (mean followup 7.3 years), and 64 patients with PFAPA (mean followup 5.2 years) were available. Patients with R92Q mutations and patients with PFAPA displayed a higher rate of self-resolution or amelioration of the fever episodes than did TRAPS patients with structural mutations. Conclusion Although some cases may progress to a more chronic disease course, the majority of children with an R92Q mutation of the TNFRSFA1 gene show a milder disease course than that in children with TNFRSFA1 structural mutations and have a high rate of spontaneous resolution and amelioration of the recurrent fever episodes.

Abstract
OBJECTIVE To evaluate the efficacy and safety of treatment with the interleukin-1 receptor antagonist anakinra in patients with tumor necrosis factor receptor-associated periodic syndrome (TRAPS) requiring high cumulative doses of steroids. METHODS Four children (mean age 9.1 years [range 4-13 years]) and 1 adult (age 33 years) with TRAPS were enrolled in the study. The 3 children with cysteine mutations (C52Y, C55Y, C43R) had prolonged and frequent attacks of fever. One child with the R92Q mutation and the adult patient with the C43R mutation displayed a more chronic disease course, with fluctuating, nearly continuous symptoms and persistent elevation of acute-phase reactant levels (including serum amyloid A [SAA]). All patients were treated with anakinra (1.5 mg/kg/day). RESULTS All of the patients had a prompt response to anakinra, with disappearance of symptoms and normalization of acute-phase reactant levels, including SAA. In all pediatric patients, anakinra was withdrawn after 15 days of treatment. After a few days (mean 5.6 days [range 3-8]) a disease relapse occurred, which dramatically responded to reintroduction of anakinra. During the following period of observation (mean 11.4 months [range 4-20 months]), the patients did not experience episodes of fever or other disease-related clinical manifestations. Levels of acute-phase reactants remained in the normal range. No major adverse reactions or severe infections were observed. CONCLUSION Continuous treatment with anakinra effectively controlled both the clinical and laboratory manifestations in patients with TRAPS and prevented disease relapses.

Abstract
Ataxia-telangiectasia is a rare multisystem neurodegenerative genetic disorder due to mutation of ATM gene. The clinical expression and the immunological abnormalities are variable and apparently not associated with the type of ATM mutations. We report on two siblings affected by A-T with different clinical and immunological presentations; in particular in one the immunological phenotype was reminiscent of hyper IgM syndrome.

Abstract
BACKGROUND Selective IgA deficiency is associated with coeliac disease, and studies have shown an increased prevalence of coeliac disease in these patients ranging from 0.71 to 30.7%, depending on the test used for screening. AIMS To determine the sensitivity of IgG anti-gliadin-antibodies and of IgG human-tissue-transglutaminase for diagnosing coeliac disease and assessing its prevalence in subjects with IgA deficiency. SUBJECTS We tested serum samples from 126 IgA-deficient children (66 female, median age: 10.8 years). METHODS All samples were analysed to measure IgG anti-gliadin-antibodies and IgG anti-human-tissue-transglutaminase. Patients testing positive to either test underwent intestinal biopsy. Subjects testing positive for IgG anti-human-tissue-transglutaminase underwent genetic testing for the human leucocyte antigen heterodimer. RESULTS Twenty-seven of 126 subjects tested positive for IgG anti-gliadin-antibodies (five of whom tested positive also for IgG anti-human-tissue-transglutaminase) and 18 (including the aforementioned five) for IgG anti-human-tissue-transglutaminase. Intestinal biopsy was performed in 37 of the 40 patients who tested positive (three subjects refused). Eleven had positive intestinal biopsies all of whom tested positive for IgG anti-human-tissue-transglutaminase, but only five of these tested positive also for IgG anti-gliadin-antibodies. All 22 patients testing positive for anti-gliadin-antibody alone had normal intestinal mucosa. All the patients who tested positive for IgG anti-human-tissue-transglutaminase and underwent genetic screening (15/18) had the coeliac-related human leucocyte antigen. Overall, coeliac disease was diagnosed in 11 of the 126 subjects with IgA deficiency (8.7%). CONCLUSIONS The prevalence of coeliac disease in subjects with total IgA deficiency was 8.7%. Assay of IgG anti-human-tissue-transglutaminase can be recommended for screening coeliac disease in IgA-deficient subjects.

Abstract
BACKGROUND Osteoprotegerin (OPG) is a secreted member of the TNF receptor superfamily. OPG is made by osteoblastic cells and is expressed in a wide variety of cell and tissue types. It acts as a decoy receptor by binding the receptor activator of nuclear factors kB (RANKL) and preventing RANKL-induced osteoclast formation and differentiation. Numerous cytokines and hormones (TGF-beta, PTH, vitamin D, glucocorticoids and oestrogens) exert their effects on osteoclastogenesis by regulating the production of OPG. PATIENTS AND METHODS In the present study we compared serum OPG and RANKL concentrations in a group of normal children (1-14 years old) with those of pair-aged children affected by different diseases [Turner's syndrome (TS), early/precocious puberty (PP) and rheumatoid arthritis (RA)]. OPG and RANKL concentrations were measured by an enzyme immunoassay method using a commercial kit. RESULTS Mean (+/- SD) OPG level in normal children was 4.05 +/- 1.63 pmol/l with no difference between males and females. OPG values in children 1-4 years old (5.87 +/- 2.22 pmol/l) were significantly higher than in children 4-14 years old (3.55 +/- 0.97 pmol/l). OPG levels in children with RA were significantly higher than in controls (6.33 +/- 2.57 pmol/l vs. 4.05 +/- 1.63 pmol/l, P < 0.01); patients with TS or PP had OPG levels superimposable to those of controls (2.61 +/- 0.67 pmol/l and 3.99 +/- 0.85 pmol/l, respectively), but in TS OPG levels were significantly lower than in age-matched females. Mean RANKL concentration in normal subjects was 0.81 +/- 1.55 pmol/l; there was a slight decline in RANKL levels with age. RANKL concentrations in subjects with TS, PP, RA and controls did not differ significantly, and did not differ from those published in adult normal subjects. CONCLUSIONS It appears from our data that OPG serum levels in healthy children aged > 4 years are similar to those present in young adult men, with higher levels in the first 4 years of life. Although the meaning of the alterations of OPG levels observed in pathological conditions is still obscure, they appear potentially interesting in view of a key role played by this protein in bone homeostasis.

Abstract
Perturbed cellular calcium homeostasis has been implicated in both apoptosis and necrosis, but the role of altered mitochondrial calcium handling in the cell death process is unclear. Recently we found that taurine, a naturally occurring amino acid potentiates Ca2+ sequestration by rat liver mitochondria. These data, which accounted for the taurine antagonism on Ca2+ release induced by the neurotoxins 1-methyl-4-phenylpyridinium plus 6-hydroxy dopamine previously reported, prompted us to investigate the effects of taurine on the permeability transition (PT) induced experimentally by high Ca2+ plus phosphate concentrations. The parameters used to measure the PT were, mitochondrial swelling, cytochrome c release and membrane potential changes. The results showed that, whereas taurine failed to reverse changes of these parameters, cyclosporin A completely reversed them. Even though these results exclude a role in PT regulation under such gross insult conditions, they cannot exclude an important role for taurine in controlling pore-opening under milder more physiological PT-inducing conditions.

Abstract
Experiments assessed whether long term exposure to 50 Hz pulsed electromagnetic fields with a peak magnetic field of 3 mT can alter the dynamics of intracellular calcium in human astrocytoma U-373 MG cells. Pretreatment of cells with 1.2 microM substance P significantly increased the [Ca(2+)](i). The same effect was also observed when [Ca(2+)](i) was evaluated in the presence of 20 mM caffeine. After exposure to electromagnetic fields the basal [Ca(2+)](i) levels increased significantly from 143 +/- 46 nM to 278 +/- 125 nM. The increase was also evident after caffeine addition, but in cells treated with substance P and substance P + caffeine we observed a [Ca(2+)](i) decrease after exposure. When we substituted calcium-free medium for normal medium immediately before the [Ca(2+)](i) measurements, the [Ca(2+)](i) was similar to that measured in the presence of Ca(2+). In this case, after EMFs exposure of cells treated with substance P, the [Ca(2+)](i), measured without and with addition of caffeine, declined from 824 +/- 425 to 38 +/- 13 nM and from 1369 +/- 700 to 11 +/- 4 nM, respectively, indicating that electromagnetic fields act either on intracellular Ca(2+) stores or on the plasma membrane. Moreover the electromagnetic fields that affected [Ca(2+)](i) did not cause cell proliferation or cell death and the proliferation indexes remained unchanged after exposure.

Abstract
Intracellular Ca(2+) mobilization and release into mammal CSF plays a fundamental role in the etiogenesis of fever induced by the proinflammatory cytokine interleukin-1beta (IL-1beta) and other pyrogens. The source and mechanism of IL-1beta-induced intracellular Ca(2+) mobilization was investigated using two experimental models. IL-1beta (10 ng/ml) treatment of rat striatal slices preloaded with (45)Ca(2+) elicited a delayed (30 min) and sustained increase (125-150%) in spontaneous (45)Ca(2+) release that was potentiated by l-arginine (300 microm) and counteracted by N-omega-nitro-l-arginine methyl ester (l-NAME) (1 and 3 mm). The nitric oxide (NO) donors diethylamine/NO complex (sodium salt) (0.3 and 1 mm) and spermine/NO (0.1 and 0.3 mm) mimicked the effect of IL-1beta on Ca(2+) release. IL-1beta stimulated tissue cGMP concentration, and dibutyryl cGMP enhanced Ca(2+) release. The guanyl cyclase inhibitors 1H-[1,2, 4]oxadiazole[4,3-a] quinoxalin-1-one (100 microm) and 6-[phenylamino]-5,8 quinolinedione (50 microm) counteracted Ca(2+) release induced by 2.5 but not 10 ng/ml IL-1beta. Ruthenium red (50 microm) and, to a lesser extent, heparin (3 mg/ml) antagonized IL-1beta-induced Ca(2+) release, and both compounds administered together completely abolished this response. Similar results were obtained in human astrocytoma cells in which IL-1beta elicited a delayed (30 min) increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) (402 +/- 71.2% of baseline), which was abolished by 1 mm l-NAME. These data indicate that the NO/cGMP-signaling pathway is part of the intracellular mechanism transducing IL-1beta-evoked Ca(2+) mobilization in glial and striatal cells and that the ryanodine and the inositol-(1,4,5)-trisphosphate-sensitive Ca(2+) stores are involved.

Abstract
We evaluated the effects of 50 Hz pulsed electromagnetic fields (EMFs) with a peak magnetic field of 3 mT on human astrocytoma cells. Our results clearly demonstrate that, after the cells were exposed to EMFs for 24 h, the basal [Ca(2+)](i) levels increased significantly from 124+/-51 nM to 200+/-79 nM. Pretreatment of the cells with 1.2 microM substance P increased the [Ca(2+)](i) to 555+/-278 nM, while EMF exposure caused a significant drop in [Ca(2+)](i) to 327+/-146 nM. The overall effect of EMFs probably depends on the prevailing Ca(2+) conditions of the cells. After exposure, the proliferative responses of both normal and substance P-pretreated cells increased slightly from 1.03 to 1.07 and 1.04 to 1.06, respectively. U-373 MG cells spontaneously released about 10 pg/ml of interleukin-6 which was significantly increased after the addition of substance P. Moreover, immediately after EMF exposure and 24 h thereafter, the interleukin-6 levels were more elevated (about 40%) than in controls. On the whole, our data suggest that, by changing the properties of cell membranes, EMFs can influence Ca(2+) transport processes and hence Ca(2+) homeostasis. The increased levels of interleukin-6 after 24 h of EMF exposure may confirm the complex connection between Ca(2+) levels, substance P and the cytokine network.

Abstract
In the 5 X-linked agammaglobulinemia (XLA) patients studied we show that memory T cells are present and that T lymphocytes proliferate normally to mitogens, monoclonal antibodies and, in particular, to recall antigens demonstrating normal in vivo T cell priming despite the absence of B cells. Furthermore, in vitro T cell activation in response to both T cell receptor-independent and T-cell receptor-dependent signals leads to a pattern of cytokine production characteristic of primed T cells and necessary for normal T cell function. These data are in good agreement with results obtained in gene-targeted mice and further support the concept that the absence of B cells does not impair induction of in vivo T cell memory and effector function which is generally considered to be of great importance in conferring protection against viral infections. Thus, while there is no risk of inducing infections in XLA patients by administering vaccines containing killed viruses or recombinant viral proteins, stimulation of T cell immunity by such vaccines may be of potential benefit particularly in the defense against infections with viruses such as the hepatitis B virus to which hypogammaglobulinemic patients are particularly exposed.

Abstract
BACKGROUND Hydrolysed casein and whey protein formulas have been developed with the aim of preventing sensitization in infants at high risk of cow milk allergy. Subsequently these products have also been used for treatment of children with cow milk allergy. However, severe reactions have occurred in some allergic infants fed with these formulas raising doubts about their absolute safety and suggest the need for developing in vitro techniques for detection of eventual residual allergenic activity in such preparations. OBJECTIVES Our purpose was to evaluate the usefulness of monoclonal and polyclonal antibodies against casein components (alpha, beta and kappa casein) as reagents for the detection of the residual antigenic activity of casein components in several hydrolysed formulas. METHODS The monoclonal and polyclonal antibodies were produced according to standard procedures by immunizing female Balb/c mice with casein fraction (a mixture of alpha, beta and kappa casein). ELISA assays were developed to test the specificity of the antibodies and to detect and evaluate the amount of residual antigenic activity of the casein components in hydrolysed formulas. RESULTS Use of polyclonal antiserum specific for casein allowed detection of residual antigenic activity of casein components in all partial hydrolysates and in the two extensive whey protein hydrolysates in the amounts ranging from 0.05 to 0.67% of total protein. No such activity was detectable in either the two extensive casein hydrolysates tested or the aminoacid based formula. The polyclonal antiserum proved to be more suitable than monoclonals for detecting residual antigenic activity in the hydrolysates. The monoclonal antibodies were directed against epitopes expressed on different casein components. CONCLUSIONS In this study the ELISA inhibition assay with polyclonal antibodies specific for casein components of cow milk proved to be a sensitive method for estimating residual antigenicity in the hydrolysed formulas commercially available for infants with cow milk allergy suggesting their potential application for the quality control of hypoallergenic infant formulas.

Abstract
We report the case of a boy with low expression of HLA class I molecules on peripheral blood mononuclear cells, which is associated with immunodeficiency. The patient, who had a Marfan-like phenotype, had chronic deep skin ulcers and sinobronchiectasis. Immunohistologic examination of the ulcerated skin showed a dense perivascular infiltrate composed of normal mature lymphocytes and macrophages. All cells in the infiltrate showed an apparently normal expression of HLA class I molecules, but intraepidermal dendritic Langerhans' cells were negative for CD1a, an antigen that is a highly specific marker for these cells and is abundantly expressed in some self-healing forms of cutaneous lesions. It is therefore speculated that a defective expression of CD1a molecules can contribute to the chronic persistence of deep skin ulcers, which have already been reported in association with defective expression of HLA class I molecules.

Abstract
BACKGROUND Reported frequencies of celiac disease in selective IgA deficiency in childhood vary widely and this is probably due to the different characteristics of the patients studied and to the different criteria used for intestinal biopsy: all patients or only those with symptoms of malabsorption. Diagnosis of celiac disease is of considerable importance in IgA deficiency because of its increased frequency and also because avoidance of dietary gluten permits elimination of the symptoms and complications of celiac disease. OBJECTIVES To obtain a more reliable estimate of the incidence of celiac disease in childhood IgA deficiency jejunal biopsies were performed in 65 consecutively diagnosed IgA-deficient children whose parents consented. Some clinical and laboratory parameters including IgA-antigliadin and IgG-antigliadin antibodies were evaluated to predict their usefulness in selecting IgA-deficient patients for intestinal biopsy. METHODS All IgA-deficient patients had serum IgA levels below 5 mg/dL and salivary IgA below 0.5 mg/dL. Jejunal biopsy was performed using a peroral Watson capsule and IgA-antigliadin and IgG-antigliadin antibodies were performed by an ELISA assay. RESULTS Biopsy findings of severe villous atrophy permitted diagnosis of celiac disease in 7.7% (5/65 children). IgG-antigliadin antibody levels, elevated in 16 patients including all five celiacs, were the best parameter for predicting celiac disease and gave no false negatives. CONCLUSIONS The 7.7% frequency of celiac disease observed in these IgA-deficient children is about 20 times higher than in the general Italian population, and the lowest among the studies biopsying all patients; this is probably attributable to the presence of a substantial proportion of healthy children (20/65) and very few (2/65) with autoimmune disorders. The elevated sensitivity and negative-predictive value of IgG-antigliadin antibodies lead us to suggest that positive IgG-antigliadin antibodies can be used to select IgA-deficient children for jejunal biopsy with a very low probability of missing celiac disease while allowing a drastic reduction in the number of biopsies performed.

Abstract
A history of poor growth in early childhood associated with persistent diarrhea and iron deficiency anemia led to a diagnosis of celiac disease in a 9-yr-old boy hospitalized for acute rhabdomyolysis. Elevated serum creatine kinase levels had been documented over the previous years, and Becker's muscular dystrophy was diagnosed by immunostaining of dystrophin and DNA analysis.

Abstract
STUDY OBJECTIVE To estimate the incidence rate of newly diagnosed cases of coeliac disease in Italy. DESIGN This was a descriptive study of coeliac disease incidence in the period 1990-91. SETTING During 1990-91 newly diagnosed cases of coeliac disease were signalled by several sources including diagnostic records of departments of paediatrics, general medicine and gastroenterology, national health service records for the supply of gluten free diets and the archives of the Italian Coeliac Society. PATIENTS Altogether 1475 cases were flagged throughout Italy, 478 of whom were selected, corresponding to 270 individual patients from a target population resident in four areas: Provices of Turin and Cuneo (Piedmont Region, northern Italy); Province of Brescia (Lombardia Region, northern Italy); Umbria Region (central Italy) and Sardinia Region (insular Italy). Only for these areas were patients flagged from several sources and the reference population was identifiable. MAIN RESULTS The overall crude incidence rates for all ages per 100,000 residents per year were 2.4, 2.7, 1.5, and 1.7 in the four areas, respectively. The childhood cumulative incidence rates (aged < or = 15 years) per 100,000 live births were 143, 141, 72, and 80 respectively. The mean ages at diagnosis were similar for both childhood and adult cases throughout the areas--these were around 4 and 34 years respectively. For each area, the incidence rate was constantly higher in the main city than elsewhere. Using the capture-recapture method, an estimated completeness of case archives of 0.84 was obtained, whereas this figure was only 0.47 for hospital sources. CONCLUSIONS This population based study on the incidence of coeliac disease shows that several information sources should be used to avoid underestimation. The incidence rate of coeliac disease in Italy was among the highest in Europe, and was widely variable showing highest figures in Piedmont and Lombardia and the lowest in Umbria and Sardinia. This trend was not due to different age at diagnosis, which suggests variable diagnostic awareness of the disease rather than different environmental patterns affecting the clinical presentation.

Abstract
We describe a 9-year-old boy with Wiskott-Aldrich syndrome and IgM-rheumatoid factor-positive arthritis who presented expansion of two distinct subsets (one CD8dim and the other CD8-) of large granular lymphocytes. Natural killer activity against the K-562 cell line was absent. An increased percentage of CD5+ B cells was also observed. Since patients with Wiskott-Aldrich syndrome are at risk of developing autoimmune disorders - conditions in which increased CD5+ B cells have been observed - the high percentage of CD5+ B cells together with the presence of IgM-rheumatoid factor and anti-platelet antibodies may represent an early manifestation of an autoimmune process. The possible relationship between CD5+ B cells and large granular lymphocyte expansion is discussed.

Abstract
The influence of nutrient absorption, caloric content, and diet on lipoprotein (a) [Lp(a)] concentration is uncertain. To our knowledge, there are no reports on Lp(a) behavior in malabsorption. Serum lipids and Lp(a) concentrations were evaluated in 17 celiac patients (5 male and 12 female patients; age range, 1-24 years) when the diagnosis was established and after a 3-month gluten-free diet. Mean total and low-density lipoprotein cholesterol did not show significant change, while mean high-density lipoprotein cholesterol rose and triglycerides decreased significantly after the diet. The Lp(a) concentration remained unchanged in all patients (median values, 35 mg/L before and 40 mg/L after the diet). Our results suggest that, in our patients, the lipoprotein profile was influenced by the gluten-free diet, while the Lp(a) concentration was not modified.
