Genetic and clinical aspects of Wolfram syndrome 1, a severe neurodegenerative disease.

Wolfram syndrome 1 (WS1) is a rare autosomal recessive neurodegenerative disease characterized by diabetes insipidus, diabetes mellitus, optic atrophy, deafness, and other abnormalities.

Key-role of thyrotropin deficiency in disclosing craniopharyngioma diagnosis in a short girl with Hashimoto's thyroiditis.

In a short girl with celiac disease and Hashimoto's thyroiditis (HT), suspicion of an associated pituitary lesion was suggested by the finding of a thyroid function pattern that was not compatible with HT-related hypothyroidism (low FT4 with normal TSH). This case report reinforces the view that the finding of a normal TSH in presence of a low FT4 should always alert pediatricians and raise suspicion of central hypothyroidism, even when a primary thyroid disease has been already identified. In this case TSH deficiency played a critical role in disclosing diagnosis of craniopharyngioma (CP). Therefore, the subsequent work-up was directed towards investigating pituitary function and morphology. Endocrinological investigations evidenced a picture of TSH and other pituitary hormone deficiency, whereas magnetic resonance imaging revealed an intrasellar CP. Therefore, in this case TSH deficiency played a key-role in disclosing CP diagnosis.

APECED syndrome in childhood: clinical spectrum is enlarging.

Autoimmune polyendocrinopathy-candidiasis-ectodermal-distrophy (APECED) is a rare autosomal recessive disease, which is mainly characterized by the association of many autoimmune diseases, with a classic triad including chronic mucocutaneous candidiasis, hypoparathyroidism and adrenocortical failure. Its clinical spectrum has significantly enlarged in the last years and other non-classic components have been recently described. Aim of this review was to alert pediatricians to these novel clinical aspects of this syndrome, that have been recently included among the autoimmune APECED manifestations: a) chronic lung disease, that may evolve to cor pulmonale and terminal respiratory failure; b) chronic inflammatory demyelinating polineuropathy, with progressive muscular weakness of both arms and legs and sensory loss; c) gastrointestinal dysfunction, with recurrent diarrhea, malabsorption and steatorrhea or chronic constipation. For each of these novel components of APECED, specific autoantibodies against either lung autoantigens or peripheral nerves or tryptophan hydroxylase have been just recently identified.

Frequency of genetic defects in combined pituitary hormone deficiency: a systematic review and analysis of a multicentre Italian cohort.

OBJECTIVE: Combined pituitary hormonal deficiency (CPHD) can result from mutations within genes that encode transcription factors. This study evaluated the frequency of mutations in these genes in a cohort of 144 unrelated Italian patients with CPHD and estimated the overall prevalence of mutations across different populations using a systematic literature review. MATERIAL AND METHODS: A multicentre study of adult and paediatric patients with CPHD was performed. The PROP1, POU1F1, HESX1, LHX3 and LHX4 genes were analysed for the presence of mutations using direct sequencing. We systematically searched PubMed with no date restrictions for studies that reported genetic screening of CPHD cohorts. We only considered genetic screenings with at least 10 individuals. Data extraction was conducted in accordance with the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS: Global mutation frequency in Italian patients with CPHD was 2·9% (4/136) in sporadic cases and 12·5% (1/8) in familial cases. The worldwide mutation frequency for the five genes calculated from 21 studies was 12·4%, which ranged from 11·2% in sporadic to 63% in familial cases. PROP1 was the most frequently mutated gene in sporadic (6·7%) and familial cases (48·5%). CONCLUSION: The frequency of defects in genes encoding pituitary transcription factors is quite low in Italian patients with CPHD and other western European countries, especially in sporadic patients. The decision of which genes should be tested and in which order should be guided by hormonal and imaging phenotype, the presence of extrapituitary abnormalities and the frequency of mutation for each gene in the patient-referring population.

Cadmium delays puberty onset and testis growth in adolescents.

OBJECTIVE: Cadmium (Cd) has been shown to impair pubertal development in experimental animals. However, no data are available for male adolescents with increased urinary cadmium levels. DESIGN: The aim of this cross-sectional study was to evaluate pubertal onset and pituitary-gonadal axis hormones in male adolescents with increased urinary levels of Cd. SUBJECTS: We studied 111 males, aged 12-14 years living in the Milazzo-Valle del Mela area. A control age-matched population (n = 60) living 28-45 km far from the industrial site was also enrolled. MEASUREMENTS: Pubertal stages were assessed by clinical examination according to Tanner's score. Mean testicular volume was also investigated by ultrasound examination. Urinary Cd concentration and blood levels of FSH, LH, testosterone and inhibin B were also investigated. RESULTS: Cd levels were significantly higher in adolescents living in the Milazzo-Valle del Mela area, compared to both age-matched subjects living far from the industrial plants and the reference values. Our population showed also a delayed onset of puberty, a smaller testicular volume and lower testosterone levels. An inverse correlation was found between urinary Cd and testicular volume (r = -0·25; P = 0·0008), testosterone levels (Spearman's r = -0·0·37; two-tailed P < 0·0001) and LH levels (Spearman's r = 0·048; P < 0·05). Testosterone levels were positively correlated with testicular volume (Spearman's r = 0·48; P < 0·0001). CONCLUSIONS: This study, for the first time, suggests that increased Cd burden is associated with delayed onset of puberty in male adolescents and impaired testicular growth.

Blockade of the JNK signalling as a rational therapeutic approach to modulate the early and late steps of the inflammatory cascade in polymicrobial sepsis.

Cecal ligation and puncture (CLP) is an experimental polymicrobial sepsis induced systemic inflammation that leads to acute organ failure. Aim of our study was to evaluate the effects of SP600125, a specific c-Jun NH2-terminal kinase (JNK) inhibitor, to modulate the early and late steps of the inflammatory cascade in a murine model of CLP-induced sepsis. CB57BL/6J mice were subjected to CLP or sham operation. Animals were randomized to receive either SP600125 (15 mg/kg) or its vehicle intraperitoneally 1 hour after surgery and repeat treatment every 24 hours. To evaluate survival, a group of animals was monitored every 24 hours for 120 hours. Two other animals were sacrificed 4 or 18 hours after surgical procedures; lung and liver samples were collected for biomolecular and histopathologic analysis. The expression of p-JNK, p-ERK, TNF-α, HMGB-1, NF-κB, Ras, Rho, Caspase 3, Bcl-2, and Bax was evaluated in lung and liver samples; SP600125 improved survival, reduced CLP induced activation of JNK, NF-κB, TNF-α, and HMGB-1, inhibited proapoptotic pathway, preserved Bcl-2 expression, and reduced histologic damage in both lung and liver of septic mice. SP600125 protects against CLP induced sepsis by blocking JNK signalling; therefore, it can be considered a therapeutic approach in human sepsis.

Hyperuniformity in phase ordering: the roles of activity, noise, and non-constant mobility.

Hyperuniformity emerges generically in the coarsening regime of phase-separating fluids. Numerical studies of active and passive systems have shown that the structure factorS(q) behaves asqςforq → 0, with hyperuniformity exponentς = 4. For passive systems, this result was explained in 1991 by a qualitative scaling analysis of Tomita, exploiting isotropy at scales much larger than the coarsening length. Here we reconsider and extend Tomita's argument to address cases of active phase separation and of non-constant mobility, again findingς = 4. We further show that dynamical noise of varianceDcreates a transientς = 2 regime forq^≪q^∗∼Dt[1-(d+2)ν]/2, crossing over toς = 4 at largerq^. Here,νis the coarsening exponent for the domain sizeℓ, such thatℓ(t)∼tν, andq^∝qℓis the rescaled wavenumber. In diffusive coarseningν=1/3, so the rescaled crossover wavevectorq^∗vanishes at large times whend⩾2. The slowness of this decay suggests a natural explanation for experiments that observe a long-livedς = 2 scaling in phase-separatingactivefluids (where noise is typically large). Conversely, ind = 1, we demonstrate that with noise theς = 2 regime survives ast→∞, withq^∗∼D5/6. (The structure factor is not then determined by the zero-temperature fixed point.) We confirm our analytical predictions by numerical simulations of continuum theories for active and passive phase separation in the deterministic case and of Model B for the stochastic case. We also compare them with related findings for a system near an absorbing-state transition rather than undergoing phase separation. A central role is played throughout by the presence or absence of a conservation law for the centre of mass positionRof the order parameter field.

Serum thyrotropin concentration in children with isolated thyroid nodules.

OBJECTIVE: To investigate the correlation between serum thyroid-stimulating hormone (TSH) concentration and nodule nature in pediatric patients with thyroid nodules, with the aim of identifying a marker able to differentiate benign and malignant nodules. STUDY DESIGN: This was a retrospective analysis of serum TSH concentrations in a multicentric case series of 125 pediatric patients with benign and malignant thyroid nodules. RESULTS: Of the 125 patients, 99 had benign thyroid nodules and 26 had differentiated thyroid cancer (24 papillary and 2 follicular). Final diagnosis was based on surgery in 57 cases and on a benign cytology plus clinical follow-up in 68 cases. Serum TSH concentration was significantly higher in patients with thyroid cancer compared with those with benign nodules (3.23 ± 1.59 mU/L vs 1.64 ± 0.99 mU/L; P < .001). Binary logistic regression analysis revealed that serum TSH was the sole predictor of malignancy (P < .001). Dividing the patient cohort into 5 groups based on serum TSH quintiles (TSH cutoffs 0.40, 1.00, 1.50, 1.80, and 2.80 mU/L), we observed that cancer prevalence increased in parallel with serum TSH (P < .001), with respective rates of 0%, 4%, 16%, 32%, and 52% in the 5 quintile groups. CONCLUSION: Because cases with malignant nodules are most likely seen in the upper normal serum TSH range (ie, >2.8 mU/L), serum TSH concentration can serve as a predictor of thyroid cancer in pediatric patients with thyroid nodules and can inform the decision of when to submit patients to further investigation by cytology.

Pulmonary autoimmunity as a feature of autoimmune polyendocrine syndrome type 1 and identification of KCNRG as a bronchial autoantigen.

Patients with autoimmune polyendocrine syndrome type 1 (APS-1) suffer from multiple organ-specific autoimmunity with autoantibodies against target tissue-specific autoantigens. Endocrine and nonendocrine organs such as skin, hair follicles, and liver are targeted by the immune system. Despite sporadic observations of pulmonary symptoms among APS-1 patients, an autoimmune mechanism for pulmonary involvement has not been elucidated. We report here on a subset of APS-1 patients with respiratory symptoms. Eight patients with pulmonary involvement were identified. Severe airway obstruction was found in 4 patients, leading to death in 2. Immunoscreening of a cDNA library using serum samples from a patient with APS-1 and obstructive respiratory symptoms identified a putative potassium channel regulator (KCNRG) as a pulmonary autoantigen. Reactivity to recombinant KCNRG was assessed in 110 APS-1 patients by using immunoprecipitation. Autoantibodies to KCNRG were present in 7 of the 8 patients with respiratory symptoms, but in only 1 of 102 APS-1 patients without respiratory symptoms. Expression of KCNRG messenger RNA and protein was found to be predominantly restricted to the epithelial cells of terminal bronchioles. Autoantibodies to KCNRG, a protein mainly expressed in bronchial epithelium, are strongly associated with pulmonary involvement in APS-1. These findings may facilitate the recognition, diagnosis, characterization, and understanding of the pulmonary manifestations of APS-1.

Fibroscan: a new noninvasive method for evaluation of liver dysfunction in Turner syndrome.

BACKGROUND: Raised liver enzyme value is frequently detected in patients with Turner syndrome (TS), but its clinical importance is still unclear. OBJECTIVE: To investigate the entity of liver involvement in TS and to avoid the invasiveness of liver biopsy, we planned to measure liver stiffness by transient elastography (TE). DESIGN: Cross-sectional study. PATIENTS AND METHODS: Twenty-five consecutive patients with TS and a chronological age ≥ 12·5 years (mean age = 21·7 years), full pubertal development and final height's achievement were enrolled and investigated by blood biochemical analyses [glucose, insulin, aspartate-aminotransferase (AST), alanine-aminotransferase (ALT), gamma-glutamil transferase (GGT), alkaline phosphatase, cholesterol, triglyceride, HDL-cholesterol], ultrasonography and TE of the liver. RESULTS: Of 25, 7 subjects (28%) showed liver enzyme levels higher than the normal upper limit. Mean liver stiffness value in the entire study group was 4·5 ± 1·7 kPa, being significantly higher in patients with abnormal liver enzymes than in those with normal liver biochemistry (6·0 ± 2·9 vs. 4·0 ± 0·9, P < 0·05). Strong correlations were found between TE values and ALT (P < 0·005), GGT (P < 0·0001), Body mass index (P < 0·05), HOMA index (P < 0·05), HDL-cholesterol (P < 0·05) and triglycerides (P < 0·0001). CONCLUSIONS: We can assert that (i) liver stiffness, measured by TE, strongly correlates with liver enzyme levels in patients with TS ; (ii) the increased liver stiffness in patients with TS with biochemical signs of liver dysfunction is significantly related to metabolic syndrome parameters; (iii) TE may be an useful tool to select among patients with TS with elevated liver enzymes or other metabolic risk factors, those who deserve more invasive diagnostic procedures, namely liver biopsy, for the best characterisation of liver damage.

Transient natural killer deficiency in a boy with herpes simplex virus-associated recurrent erythema multiforme.

Erythema multiforme is characterized by itching macules, papules and bullae, symmetrically distributed on the dorsum of the hands. They can follow the administration of several drugs or infections with various agents, and in particular with herpes simplex virus. The recurrent variant is very rare, especially in the paediatric age group. We describe the case of a male adolescent with recurrent erythema multiforme caused by herpes virus and transient natural killer deficiency.

Scurvy may occur even in children with no underlying risk factors: a case report.

BACKGROUND: Since ancient times, scurvy has been considered one of the most fearsome nutritional deficiency diseases. In modern developed countries, this condition has become very rare and is only occasionally encountered, especially in the pediatric population. Underlying medical conditions, such as neuropsychiatric disorders, anorexia nervosa, celiac disease, Crohn disease, hemodialysis, and severe allergies to food products may enhance the risk of developing scurvy. CASE PRESENTATION: We report the case of an otherwise healthy 3-year-old white boy who developed scurvy due to a selective restrictive diet derived from his refusal to try new food. He presented to our clinic with asthenia and refusal to walk. During hospitalization he developed severe anemia and hematochezia. A diagnosis of scurvy was assessed on the basis of nutritional history, clinical features, radiographic findings, and laboratory findings. Supplementation of ascorbic acid enabled a prompt resolution of symptoms. CONCLUSIONS: Scurvy is caused by vitamin C deficiency. Cutaneous bleeding, mucosal bleeding, and anemia represent typical manifestations of the disease. These symptoms are directly connected to ascorbic acid involvement in collagen biosynthesis. Some radiographic findings can be useful for the diagnosis. Treatment aims to normalize serum levels of vitamin C in order to counteract the deprivation symptoms. The present case report demonstrates that scurvy may sporadically occur in pediatric patients, even in individuals with no predisposing medical conditions and/or potential risk factors.

Evaluation of the autoimmune regulator (AIRE) gene mutations in a cohort of Italian patients with autoimmune-polyendocrinopathy-candidiasis-ectodermal-dystrophy (APECED) and in their relatives.

OBJECTIVE: Autoimmune-polyendocrinopathy-candidiasis-ectodermal-dystrophy (APECED) is a rare syndrome characterized by chronic candidiasis, chronic hypoparathyroidism and Addison's disease. APECED has been associated with mutations in autoimmune regulator (AIRE) gene. Our aim is to perform a genetic analysis of the AIRE gene in Italian APECED patients and in their relatives. Design AIRE mutations were determined by DNA sequencing in all subjects. Patients were tested for clinical autoimmune or non-autoimmune diseases, or for organ and non-organ specific autoantibodies. PATIENTS: A total of 24 Italian patients with APECED (15 from the Venetian region, 2 from Southern-Tyrol, 4 from Apulia, 3 from Sicily), 25 relatives and 116 controls were studied. RESULTS: Ten out of the 15 Venetian patients (66%) were homozygous for R257X or compound heterozygous with 1094-1106del13. One patient was homozygous for 1094-1106del13 and another for R139X. A novel mutation (1032-1033delGT) in combination with 1094-1106del13 was identified in one patient. No mutations were found in two cases. Two patients from Southern Tyrol were homozygous for R257X and for 1094-1106del13bp. All patients from Apulia were homozygous or heterozygous for W78R combined with Q358X. The patients from Sicily were homozygous for R203X or compound heterozygous with R257X. The analysis of the genotype-phenotype revealed that patients carrying 1094-1106del13 at the onset of Addison's disease were significantly older than those carrying other mutations. The genetic study of 25 relatives identified 20 heterozygous subjects. They suffered from various autoimmune and non-autoimmune diseases but no major disease of APECED was found. CONCLUSION: These data demonstrate the great genetic heterogeneity for the AIRE mutations in Italian APECED patients, and that the heterozygosity for AIRE mutations do not produce APECED.

Menarcheal timing in intensively treated girls with type 1 diabetes mellitus.

BACKGROUND AND AIM: Previous studies on menarcheal age (MA) in type 1 diabetes mellitus (T1DM) have shown conflicting results about the effects of DM, but most lack a control group. The present study design is peculiar in that it covers a study population of 73 intensively treated menarcheal adolescents with premenarcheal onset of T1DM (Group A), whose MA was compared with that recorded in three control populations: the first one consisting of 280 healthy adolescents, the second one consisting of 20 T1DM adolescents with postmenarcheal DM onset (Group B) and the third one represented by the respective mothers. METHODS AND RESULTS: MA of Group A patients was significantly delayed when compared with the respective mothers, healthy controls and Group B patients. By contrast MA of Group B girls was superimposable to the one of both their respective mothers and healthy controls. In Group A MA was strongly related (p<0.0005) to HbA1c at the time of menarche and to average HbA1c concentrations during the last years before menarche. In Group A no relationship between patients' and mothers' MAs was found, whilst such a correlation was significant in Group B. CONCLUSIONS: (a) MA is significantly delayed in girls with premenarcheal presentation of T1DM, even if intensively treated; (b) menarcheal retardation is more severe in the patients with suboptimal metabolic control at the time of menarche; and (c) MA in premenarcheal presenting T1DM is irrespective of maternal MA, age and HbA1c concentrations at DM presentation, body mass index and daily insulin dose at menarche.

Chronic inflammatory demyelinating polyneuropathy as a possible novel component of autoimmune poly-endocrine-candidiasis-ectodermal dystrophy.

We describe two unrelated boys with autoimmune poly-endocrine-candidiasis-ectodermal dystrophy syndrome (APECED) who, in addition to manifesting the most common symptoms (chronic mucocutaneous candidiasis, hypoparathyroidism and Addison's disease), developed progressive muscular weakness in both the proximal and distal limbs, sensory loss and absent tendon reflexes. Electrophysiological studies disclosed a reduction of nerve conduction velocity in both patients that was consistent with the diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP).This diagnosis was supported by histological demyelination in nerve biopsy specimens with patchy CD4, CD8 and CD68-positive cell infiltration in the first patient and increased protein content in the cerebrospinal fluid in the second patient. Our cases represent the first report of an association between APECED and CIDP, in which peripheral nerve demyelination may represent a novel disease component in APECED. Our findings highlight the need to explore apparently rare manifestations in patients with APECED.

Gynecomastia disclosing diagnosis of Leydig cell tumour in a man with thalassemia, secondary hypogonadism and testis microlithiasis.

Aim of this paper is to report about a 35-year old man suffering from beta-Thalassemia major and longstanding untreated hypogonadotropic hypogonadism, who was referred because of a recent onset and painful bilateral gynecomastia, with no palpable testicular masses. Due to the finding of a solid mass at left testis ultrasonography, monolateral testicular exeresis was performed and histology revealed a Leydig Cell Tumour and testicular microlithiasis. Post-surgical restoration of testosterone/estradiol ratio under testosterone therapy was followed by a very rapid reduction of gynecomastia. Our report confirms the usefulness of scrotal ultrasonography for finding an occult testicular tumour in a patient with painful and recent onset bilateral gynecomastia and underlines: a) the important role of testosterone/estradiol ratio in the pathophysiology of gynecomastia; b) the questionable significance of testicular microlithiasis as marker of testis tumours; c) the possible association between beta-Thalassemia and tumoral pathologies.

Could AGE/RAGE-Related Oxidative Homeostasis Dysregulation Enhance Susceptibility to Pathogenesis of Cardio-Metabolic Complications in Childhood Obesity?

Background: Advanced glycation end-products (AGEs) and their cell receptor (RAGE) are involved in the pathophysiology of cardio-metabolic diseases. Interaction of AGEs with RAGE results in increased generation of oxygen radicals and pro-inflammatory cytokines. Circulating soluble RAGE (sRAGE) interacts with AGEs in order to counterbalance the negative effects of AGEs-RAGE interaction. Objectives: To define factors influencing AGEs, sRAGE, AGEs/sRAGE-ratio, and advanced oxidation-protein products (AOPPs) levels and to investigate changes in oxidative balance among overweight/obese children. Materials and methods: Cross-sectional, one Center, case-control study included 41 overweight and obese children aged between 5 and 16 years and 36 lean matched controls. Inclusion criteria were: BMI ≥ 1 SD; term birth; no genetic or endocrine causes of obesity; no associated chronic diseases neither chronic therapies. All patients underwent clinical and biochemical investigations (lipid and glucose profiles, liver, renal and thyroid function tests, uric acid, C-reactive protein (CRP), AGEs, sRAGE, and AOPPs serum concentrations). Significance was established at 0.050. Results: AOPPs, AGEs/sRAGE-ratio, HOMA-IR, triglycerides, triglycerides/HDL-ratio, total cholesterol (TC)/HDL-ratio, atherogenic-index of plasma (AIP), uric acid, CRP were significantly higher, whereas sRAGE and HDL were significantly lower in overweight/obese children than controls. sRAGE was significantly negatively correlated with BMI SD, TC/HDL-ratio, CRP, AOPPs, and positively with HDL. AGE/sRAGE-ratio and AOPPs were significantly positively correlated with BMI SD, TC/HDL-ratio, AIP, CRP, and negatively with HDL. BMI SD was independently associated with AGEs/sRAGE-ratio (B = 0.06; p = 0.008), AOPPs (B = 0.13; p = 0.02), and sRAGE (B = -73.18; p = 0.000). Conclusions: We demonstrated, for the first time in a pediatric cohort, a significant higher value of AGEs/sRAGE-ratio among overweight/obese children, expression of a relative shift to oxidant from anti-oxidant factors, suggesting an AGE/RAGE-related oxidative homeostasis dysregulation that could enhance susceptibility to oxidative/inflammatory tissues damage. Severity of overweight, influencing the increase of oxidative stress in human organism and even in children, may contribute to the pathogenesis of long-term cardiovascular and metabolic alterations.
