RESUMO
Teduglutide is a glucagon-like-peptide-2 analogue that reduces the need for parenteral support in patients with short bowel syndrome (SBS). Nevertheless, data about long-term therapy with teduglutide in children are still scarce. Our objective was to describe the real-life experience with teduglutide in children with SBS over the last 5 years in Spain. This was a national multicentre and prospective study of paediatric patients with intestinal failure (IF) treated with teduglutide for at least 3 months. The data included demographic characteristics, medical background, anthropometric data, laboratory assessments, adverse events, and parenteral nutrition (PN) requirements. Treatment response was defined as a > 20% reduction in the PN requirement. The data were collected from the Research Electronic Data Capture (REDCap) database. Thirty-one patients from seven centres were included; the median age at the beginning of the treatment was 2.3 (interquartile range (IQR) 1.4-4.4) years; and 65% of the patients were males. The most frequent cause of IF was SBS (94%). The most common cause of SBS was necrotizing enterocolitis (35%). The median residual bowel length was 29 (IQR 12-40) cm. The median duration of teduglutide therapy was 19 (IQR 12-36) months, with 23 patients (74%) treated for > 1 year and 9 treated for > 3 years. The response to treatment was analysed in 30 patients. Twenty-four patients (80%) had a reduction in their weekly PN energy > 20% and 23 patients (77%) had a reduction in their weekly PN volume > 20%. Among the responders, 9 patients (29%) were weaned off PN, with a median treatment duration of 6 (IQR 4.5-22) months. The only statistically significant finding demonstrated an association between a > 20% reduction in the weekly PN volume and a younger age at the start of treatment (p = 0.028). Conclusions: Teduglutide seems to be an effective and safe treatment for paediatric patients with IF. Some patients require a prolonged duration of treatment to achieve enteral autonomy. Starting treatment with teduglutide at a young age is associated with a higher response rate. What is Known: ⢠Glucagon-like peptide-2 (GLP-2) plays a crucial role in the regulation of intestinal adaptation in short bowel syndrome (SBS). Teduglutide is a GLP-2 analog that reduces the need for parenteral support in patients with SBS. ⢠Data about long-term therapy with teduglutide in children in real life are still scarce. What is New: ⢠Most pediatric patients with SBS respond in a satisfactory manner to teduglutide treatment. The occurrence of long-term adverse effects is exceptional. ⢠Starting treatment with the drug at a young age is associated with a greater response rate.

Tumor-necrosis-factor-α inhibitors (anti-TNF-α) are associated with an increased risk of tuberculosis (TB) disease, primarily due to reactivation of latent TB infection (LTBI). We assessed the performance of parallel LTBI screening with tuberculin skin test (TST) and QuantiFERON-TB Gold In-Tube assays (QFT-GIT) before anti-TNF-α treatment in children with immune-mediated inflammatory disorders in a low TB-burden setting. We conducted a multicenter cohort study involving 17 pediatric tertiary centers in Spain. LTBI was defined as the presence of a positive TST and/or QFT-GIT result without clinical or radiological signs of TB disease. A total of 270 patients (median age:11.0 years) were included, mainly with rheumatological (55.9%) or inflammatory bowel disease (34.8%). Twelve patients (4.4%) were diagnosed with TB infection at screening (LTBI, n = 11; TB disease, n = 1). Concordance between TST and QFT-GIT results was moderate (TST+/QFT-GIT+, n = 4; TST-/QFT-GIT+, n = 3; TST+/QFT-GIT-, n = 5; kappa coefficient: 0.48, 95% CI: 0.36-0.60). Indeterminate QFT-GIT results occurred in 10 patients (3.7%) and were associated with young age and elevated C-reactive protein concentrations. Eleven of 12 patients with TB infection uneventfully completed standard LTBI or TB treatment. During a median follow-up period of 6.4 years, only 2 patients developed TB disease (incidence density: 130 (95% CI: 20-440) per 100,000 person-years), both probable de novo infections. CONCLUSION: A substantial number of patients were diagnosed with LTBI during screening. The dual strategy identified more cases than either of the tests alone, and test agreement was only moderate. Our data show that in children in a low TB prevalence setting, a dual screening strategy with TST and IGRA before anti-TNF-α treatment is effective. WHAT IS KNOWN: ⢠The optimal screening strategy for latent tuberculosis in children with immune-mediated inflammatory disorders remains uncertain. ⢠Children receiving anti-TNF-α drugs are at increased risk of developing severe tuberculosis disease. WHAT IS NEW: ⢠A dual screening strategy, using TST and an IGRA assay, identified more children with latent tuberculosis than either of the tests alone. ⢠Identification and treatment of latent tuberculosis before initiation of anti-TNF-α therapy averted incident tuberculosis cases.

PURPOSE: We report a patient with a human cationic amino acid transporter 2 (CAT-2) defect discovered due to a suspected arginase 1 deficiency observed in newborn screening (NBS). METHODS: A NBS sample was analyzed using tandem mass spectrometry. Screen results were confirmed by plasma and urine amino acid quantification. Molecular diagnosis was done using clinical exome sequencing. Dimethylated arginines were determined by HPLC and nitrate/nitrite levels by a colorimetric assay. The metabolomic profile was analyzed using 1D nuclear magnetic resonance spectroscopy. RESULTS: A Spanish boy of nonconsanguineous parents had high arginine levels in a NBS blood sample. Plasma and urinary cationic amino acids were high. Arginase enzyme activity in erythrocytes was normal and no pathogenic mutations were identified in the ARG1 gene. Massive parallel sequencing detected two loss-of-function mutations in the SLC7A2 gene. Currently, the child receives a protein-controlled diet of 1.2 g/kg/day with protein-and amino-acid free infant formula, 30 g/day, and is asymptomatic. CONCLUSION: We identified a novel defect in human CAT-2 due to biallelic pathogenic variants in the SLC7A2 gene. The characteristic biochemical profile includes high plasma and urine arginine, ornithine, and lysine levels. NBS centers should know of this disorder since it can be detected in arginase 1 deficiency screening.

AIM: To explore the clinical presentation, course, treatment and impact of early treatment in patients with remethylation disorders from the European Network and Registry for Homocystinurias and Methylation Defects (E-HOD) international web-based registry. RESULTS: This review comprises 238 patients (cobalamin C defect n = 161; methylenetetrahydrofolate reductase deficiency n = 50; cobalamin G defect n = 11; cobalamin E defect n = 10; cobalamin D defect n = 5; and cobalamin J defect n = 1) from 47 centres for whom the E-HOD registry includes, as a minimum, data on medical history and enrolment visit. The duration of observation was 127 patient years. In 181 clinically diagnosed patients, the median age at presentation was 30 days (range 1 day to 42 years) and the median age at diagnosis was 3.7 months (range 3 days to 56 years). Seventy-five percent of pre-clinically diagnosed patients with cobalamin C disease became symptomatic within the first 15 days of life. Total homocysteine (tHcy), amino acids and urinary methylmalonic acid (MMA) were the most frequently assessed disease markers; confirmatory diagnostics were mainly molecular genetic studies. Remethylation disorders are multisystem diseases dominated by neurological and eye disease and failure to thrive. In this cohort, mortality, thromboembolic, psychiatric and renal disease were rarer than reported elsewhere. Early treatment correlates with lower overall morbidity but is less effective in preventing eye disease and cognitive impairment. The wide variation in treatment hampers the evaluation of particular therapeutic modalities. CONCLUSION: Treatment improves the clinical course of remethylation disorders and reduces morbidity, especially if started early, but neurocognitive and eye symptoms are less responsive. Current treatment is highly variable. This study has the inevitable limitations of a retrospective, registry-based design.

PURPOSE: To assess how the current practice of newborn screening (NBS) for homocystinurias compares with published recommendations. METHODS: Twenty-two of 32 NBS programmes from 18 countries screened for at least one form of homocystinuria. Centres provided pseudonymised NBS data from patients with cystathionine beta-synthase deficiency (CBSD, n = 19), methionine adenosyltransferase I/III deficiency (MATI/IIID, n = 28), combined remethylation disorder (cRMD, n = 56) and isolated remethylation disorder (iRMD), including methylenetetrahydrofolate reductase deficiency (MTHFRD) (n = 8). Markers and decision limits were converted to multiples of the median (MoM) to allow comparison between centres. RESULTS: NBS programmes, algorithms and decision limits varied considerably. Only nine centres used the recommended second-tier marker total homocysteine (tHcy). The median decision limits of all centres were ≥ 2.35 for high and ≤ 0.44 MoM for low methionine, ≥ 1.95 for high and ≤ 0.47 MoM for low methionine/phenylalanine, ≥ 2.54 for high propionylcarnitine and ≥ 2.78 MoM for propionylcarnitine/acetylcarnitine. These decision limits alone had a 100%, 100%, 86% and 84% sensitivity for the detection of CBSD, MATI/IIID, iRMD and cRMD, respectively, but failed to detect six individuals with cRMD. To enhance sensitivity and decrease second-tier testing costs, we further adapted these decision limits using the data of 15 000 healthy newborns. CONCLUSIONS: Due to the favorable outcome of early treated patients, NBS for homocystinurias is recommended. To improve NBS, decision limits should be revised considering the population median. Relevant markers should be combined; use of the postanalytical tools offered by the CLIR project (Collaborative Laboratory Integrated Reports, which considers, for example, birth weight and gestational age) is recommended. tHcy and methylmalonic acid should be implemented as second-tier markers.

OBJECTIVE: The aim of the study was to describe clinical, epidemiological, and management characteristics of food protein-induced enterocolitis syndrome (FPIES) cases in Spain. PATIENTS AND METHODS: Multicenter observational retrospective study. FPIES cases diagnosed in specialized units in Spain over 12 months in 2017 (January-December) according to the recently published international diagnostic criteria were included. RESULTS: One hundred twenty patients (53.3% boys) were included. The majority were acute cases (111) with mild-to-moderate severity (76.7%). Triggering foods were cow's milk (48/120), fish (38), egg (13), rice (12), and soy (1). The majority (84.2%) of the patients had FPIES to 1 food only. In addition to vomiting (100%), pallor (89.2%), and altered behavior (88.3%) were most frequently observed in acute forms. On the contrary, diarrhea (70%), abdominal distension (33.3%), and blood in stools (44.4%) were more frequently observed in chronic cases. Oral challenge was performed in 18.9% of the acute forms compared to 44.4% of the chronic forms. The most common treatment was intravenous fluids followed by ondansetron. Corticosteroids were used in 6 patients (5 with acute symptoms and 1 chronic). Seven patients were treated with antibiotics for suspicion of infection. Most cases of cow's milk FPIES were treated with extensively hydrolyzed formulas (69.8%). CONCLUSIONS: FPIES is not uncommon in our units. Unlike other published series, fish and egg are important triggers in our country. A greater knowledge and diffusion of the international consensus criteria will allow a better characterization of the cases and a standardization of their management.

INTRODUCTION AND OBJECTIVES: Metastatic Crohn's disease (MCD) is an extraintestinal manifestation of Crohn's disease, with biopsy as fundamental diagnostic tool. There are few references to MCD in children, with a 0.5-1% estimated incidence in adults. There is no consensus about its therapeutic approach. We describe our diagnostic and therapeutic experience in MCD. RESULTS: Four cases of MCD are described in our Pediatric Gastroenterology Unit in a tertiary care hospital. The age at diagnosis was between 7 and 13 years. Lesions appeared before the diagnosis of Crohn's disease in three of them, and during the course of the disease in another one, with genital location in three patients and bilateral pretibial region in the other. All four cases demonstrated non-caseificant granulomas on biopsy. Only two patients used exclusive enteral nutrition therapy with complete resolution, while other two cases received a combination of therapies (corticosteroids, azathioprine, tacrolimus, infliximab and adalimumab) because of recurrence. Only one case required surgery after poor clinical control. CONCLUSION: The MCD is infrequent but must always be included in the differential diagnosis of cutaneous lesions in Crohn's disease, considering it could be the debut of the disease. We will rely on biopsy anyway for definitive diagnosis. In this series the genital region is verified as the most commonly affected in children. The therapeutic approach does not differ from the management of intestinal involvement.

BACKGROUND: The clinical presentation of patients with organic acidurias (OAD) and urea cycle disorders (UCD) is variable; symptoms are often non-specific. AIMS/METHODS: To improve the knowledge about OAD and UCD the E-IMD consortium established a web-based patient registry. RESULTS: We registered 795 patients with OAD (n = 452) and UCD (n = 343), with ornithine transcarbamylase (OTC) deficiency (n = 196), glutaric aciduria type 1 (GA1; n = 150) and methylmalonic aciduria (MMA; n = 149) being the most frequent diseases. Overall, 548 patients (69 %) were symptomatic. The majority of them (n = 463) presented with acute metabolic crisis during (n = 220) or after the newborn period (n = 243) frequently demonstrating impaired consciousness, vomiting and/or muscular hypotonia. Neonatal onset of symptoms was most frequent in argininosuccinic synthetase and lyase deficiency and carbamylphosphate 1 synthetase deficiency, unexpectedly low in male OTC deficiency, and least frequently in GA1 and female OTC deficiency. For patients with MMA, propionic aciduria (PA) and OTC deficiency (male and female), hyperammonemia was more severe in metabolic crises during than after the newborn period, whereas metabolic acidosis tended to be more severe in MMA and PA patients with late onset of symptoms. Symptomatic patients without metabolic crises (n = 94) often presented with a movement disorder, mental retardation, epilepsy and psychiatric disorders (the latter in UCD only). CONCLUSIONS: The initial presentation varies widely in OAD and UCD patients. This is a challenge for rapid diagnosis and early start of treatment. Patients with a sepsis-like neonatal crisis and those with late-onset of symptoms are both at risk of delayed or missed diagnosis.

BACKGROUND: The disease course and long-term outcome of patients with organic acidurias (OAD) and urea cycle disorders (UCD) are incompletely understood. AIMS: To evaluate the complex clinical phenotype of OAD and UCD patients at different ages. RESULTS: Acquired microcephaly and movement disorders were common in OAD and UCD highlighting that the brain is the major organ involved in these diseases. Cardiomyopathy [methylmalonic (MMA) and propionic aciduria (PA)], prolonged QTc interval (PA), optic nerve atrophy [MMA, isovaleric aciduria (IVA)], pancytopenia (PA), and macrocephaly [glutaric aciduria type 1 (GA1)] were exclusively found in OAD patients, whereas hepatic involvement was more frequent in UCD patients, in particular in argininosuccinate lyase (ASL) deficiency. Chronic renal failure was often found in MMA, with highest frequency in mut(0) patients. Unexpectedly, chronic renal failure was also observed in adolescent and adult patients with GA1 and ASL deficiency. It had a similar frequency in patients with or without a movement disorder suggesting different pathophysiology. Thirteen patients (classic OAD: 3, UCD: 10) died during the study interval, ten of them during the initial metabolic crisis in the newborn period. Male patients with late-onset ornithine transcarbamylase deficiency were presumably overrepresented in the study population. CONCLUSIONS: Neurologic impairment is common in OAD and UCD, whereas the involvement of other organs (heart, liver, kidneys, eyes) follows a disease-specific pattern. The identification of unexpected chronic renal failure in GA1 and ASL deficiency emphasizes the importance of a systematic follow-up in patients with rare diseases.

INTRODUCTION: Acute acalculous cholecystitis (AAC) occurs more frequently in critically ill patients, in the immediate postoperative period, after trauma or extensive burns. It has a high rate of morbidity and mortality. Ischemia, infection and vesicular stasis are determinants in its pathogenesis. MATERIAL AND METHOD: Retrospective study including all cases of AAC diagnosed in our pediatric intensive care unit between January 1997 and December 2012. RESULTS: We included 7 patients, all associated with viral or bacterial infection. All of them suffered from abdominal pain, mainly localized in the right upper quadrant, jaundice and dark urine. Abdominal ultrasound showed thickening and hypervascularity of the gallbladder wall in all cases. The outcome was satisfactory without surgery in all patients. CONCLUSIONS: The clinical presentation is oligosymptomatic within severe systemic diseases. The AAC should be suspected in the appearance of any abdominal pain with jaundice/dark urine and hypertransaminasemia in patients suffering from critical or serious infections.

INTRODUCTION: The conventional 24-hour pH monitoring is the gold standard for the diagnosis of gastro-esophageal reflux (GER), a possible cause of Apparent Life Threatening Episodes (ALTE). However, multichannel intraluminal impedance (MII) may provide advantages. OBJECTIVES: Comparison of the results of MII and pH monitoring in patients undergoing MII-pH monitoring in the 3-year study period because of having suffered from ALTE. MATERIAL AND METHODS: Prospective study of MII-pH monitoring performed in our unit to infants < 12 months of ageadmitted for ALTE for a 3-year period. RESULTS: Thirty nine patients studied. 2,692 pH monitoring episodes, with median of 24 (IQ: 15-44) episodes/patient, 1.30 (IQ: 0.80-2.60) reflux/hour, 1 (IQ: 0-4) reflux episode > 5 min per patient and clearance of 1.20 (IQ: 0.70-2.20) min/reflux. With pH monitoring analysis, 14 children (35.9 %) could have been diagnosed as GER (8 mild, 4 moderate and 2 severe) based on the classical criteria. MII identified a total of 8,895 events; only 3,219 among them were refluxes, with a median of 75 (IQ: 54-111) per patient, 1.30 (IQ: 1.3-2.6) episodes/hour). With MII-pH monitoring combination there were 21.60 (SD 15.21) acid reflux episodes, 67.33 weekly acid (SD 32.09) and 3.34 (SD 7.23) non-acid, being finally diagnosed 33 patients as GER. CONCLUSIONS: The association of pH monitoring and MII provides additional information that improves GER diagnostic performance without posing any additional risk to the infant patient. The non-acid/weekly acid refluxes, not detected by pH monitoring, account for a high percentage of episodes, this may have diagnostic and therapeutic significance, especially in infants. Further studies are needed to assess the normality of MMI in pediatric patients.

OBJECTIVES: to describe the efficacy and safety of adalimumab (ADA) in inducing clinical remission and reducing inflammation of intestinal mucosa in children with Crohn´s disease (CD). METHODS: we carried out a descriptive, observational study with all patients diagnosed with CD and treated with ADA between January 2007 and March 2013. Disease activity was determined using the Pediatric Crohn´s Disease Activity Index (PCDAI), and the degree of mucosa inflammation by fecal calprotectin (FC). RESULTS: sixteen patients were included. Mean age at diagnosis was 10.6 ± 2.5 years, with a mean age at start of ADA treatment of 12.4 ± 1.8 years, and a median of 1.4 years (IQR 0.5-3) duration from CD diagnosis to start of treatment. Twelve patients were naïve to anti-TNF-a. The PCDAI score at start of ADA treatment was significantly reduced at 12 weeks of follow-up (31.25 IQR 26.8-37.5 vs. 1.2 IQR 0.0-5.0; p = 0.001). Similarly, the FC level decreased at 12 weeks (749 µg/g IQR 514-898 vs. 126 µg/g IQR 67.7-239.2; p = 0.02). Surgery was performed in 4 patients. Adverse events were reported in 4 patients. One patient developed lymphoma at 4 years of ADA treatment in monotherapy. CONCLUSIONS: ADA has been shown to be effective in children with moderate-to-severe CD. Treatment benefits should be weighed against side effects. Multicenter longitudinal studies with longer follow-up periods are required to determine the true efficacy and safety of long-term ADA treatment.

Background and objectives: Glycerol phenylbutyrate (GPB) has demonstrated safety and efficacy in patients with urea cycle disorders (UCDs) by means of its clinical trial program, but there are limited data in clinical practice. In order to analyze the efficacy and safety of GPB in clinical practice, here we present a national Spanish experience after direct switching from another nitrogen scavenger to GPB. Methods: This observational, retrospective, multicenter study was performed in 48 UCD patients (age 11.7 ± 8.2 years) switching to GPB in 13 centers from nine Spanish regions. Clinical, biochemical, and nutritional data were collected at three different times: prior to GPB introduction, at first follow-up assessment, and after one year of GPB treatment. Number of related adverse effects and hyperammonemic crisis 12 months before and after GPB introduction were recorded. Results: GPB was administered at a 247.8 ± 102.1 mg/kg/day dose, compared to 262.6 ± 126.1 mg/kg/day of previous scavenger (46/48 Na-phenylbutyrate). At first follow-up (79 ± 59 days), a statistically significant reduction in ammonia (from 40.2 ± 17.3 to 32.6 ± 13.9 µmol/L, p < 0.001) and glutamine levels (from 791.4 ± 289.8 to 648.6 ± 247.41 µmol/L, p < 0.001) was observed. After one year of GPB treatment (411 ± 92 days), we observed an improved metabolic control (maintenance of ammonia and glutamine reduction, with improved branched chain amino acids profile), and a reduction in hyperammonemic crisis rate (from 0.3 ± 0.7 to less than 0.1 ± 0.3 crisis/patients/year, p = 0.02) and related adverse effects (RAE, from 0.5 to less than 0.1 RAEs/patients/year p < 0.001). Conclusions: This study demonstrates the safety of direct switching from other nitrogen scavengers to GPB in clinical practice, which improves efficacy, metabolic control, and RAE compared to previous treatments.
RESUMO
The establishment of national neonatal screening systems has resulted in improved quality of life and life expectancy in patients with phenylketonuria (PKU). This has led to the development of multidisciplinary treatment units for adult patients with PKU. We present a retrospective descriptive study of a cohort of 90 adult patients (>16 years) with PKU under active follow-up in two reference centers in Andalusia. We analyzed disease severity, treatment type, demographic variables, cardiovascular risk factors, vitamin and hormone profiles, and bone metabolism. The median (interquartile range)age was 29 (23−38) years, 47 (52.2%) were women and 43 (47.8%) were men. Eighty (88.9%) had classical PKU, five (5.6%) moderate PKU, and five (5.6%) mild PKU. Diagnosis was by neonatal screening in 62 (68.9%) of the patients. The rest had late diagnosis. Treatment with sapropterin was given to 18 (20%) patients and diet and nutrition therapy to 72 (80%). There was adequate metabolic control according to Phe levels in 43 (47.78%) patients. Body mass index was 26.61 (22.7−31.1) kg/m2. Twenty-six (29.2%) patients had obesity, 7 (7.9%) hypertension, 2 (2.2%) type 2 diabetes, 26 (28.89%) dyslipidemia, 14 (15.6%) elevated total cholesterol, 9 (15.8%) decreased high-density lipoprotein cholesterol and 16 (17.8%) hypertriglyceridemia. Seven (10.3%) patients had osteoporosis and 28 (41.17%) osteopenia. Twenty-six (30.6%) had vitamin D (25OH) deficiency and four (4.5%) vitamin B12 deficiency. Although we observed no differences with most vascular risk factors, we found a high prevalence of obesity in relation to the age of the cohort. A continued evaluation of comorbidities in these patients is therefore needed, despite adequate metabolic control.

Juvenile polyposis syndrome (JPS) is a rare disease with an autosomal dominant inheritance pattern characterized by the development of multiple hamartomatous polyps in the gastrointestinal tract. The most frequent signs and symptoms are recurrent abdominal pain, rectal bleeding, anemia, and iron deficiency. The treatment of JPS is symptomatic, requiring serial endoscopic polypectomies or intestinal resections in the most severe cases. We describe the clinical case of a patient with JPS with a childhood juvenile polyposis phenotype because of a mutation on the SMAD4 gene, who received treatment with sirolimus successfully.
RESUMO
BACKGROUND: Mucopolysaccharidosis (MPS) IVA or Morquio A syndrome is a progressive and disabling disease characterized by a deficiency of the enzyme N-acetylgalactosamine-6-sulphate sulphatase. Its clinical presentation is very heterogeneous and poorly understood in adults. The aim of this study was to describe the clinical manifestations of MPS IVA in adult patients in Spain and to assess their health-related quality of life (HRQoL). RESULTS: Thirty-three patients from nine reference centres participated in the study. The median age was 32 (interquartile range [IQR]: 20.5-40.5) years. The phenotype was classical in 54.5% of patients, intermediate in 33.3% of patients, and non-classical in 12.1% of patients. The most common clinical manifestation was bone dysplasia, with a median height of 118 (IQR: 106-136) cm. Other frequent clinical manifestations were hearing loss (75.7%), ligamentous laxity (72.7%), odontoid dysplasia (69.7%), limb deformities that required orthopaedic aids (mainly hip dysplasia and genu valgus) (63.6%), and corneal clouding (60.6%). In addition, 36.0% of patients had obstructive sleep apnoea/hypopnoea syndrome and 33.3% needed non-invasive ventilation. Cervical surgery and varisation osteotomy were the most common surgical interventions (36.4% each). Almost 80% of patients had mobility problems and 36.4% used a wheelchair at all times. Furthermore, 87.9% needed help with self-care, 33.3% were fully dependent, and 78.8% had some degree of pain. HRQoL according to the health assessment questionnaire was 1.43 (IQR: 1.03-2.00) in patients with the non-classical phenotype, but 2.5 (IQR: 1.68-3.00) in those with the classical phenotype. Seven patients were initiated on enzyme replacement therapy (ERT), but two of them were lost to follow-up. Lung function improved in four patients and slightly worsened in one patient. The distance achieved in the six-minute walk test increased in the four patients who could perform it. HRQoL was better in patients treated with elosulfase alfa, with a median (IQR) of 1.75 (1.25-2.34) versus 2.25 (1.62-3.00) in patients not treated with ERT. CONCLUSIONS: The study provides real-world data on patients with MPS IVA. Limited mobility, difficulties with self-care, dependence, and pain were common, together with poor HRQoL. The severity and heterogeneity of clinical manifestations require the combined efforts of multidisciplinary teams.

Chronically active ulcerative colitis (UC) constitutes a challenge in an era where medical therapeutic options have increased while experience with colectomies has decreased. The change in the therapeutic paradigm of the disease means that patients with chronically active UC are being managed waiting to find their therapeutic target. We present 2 cases of children with chronically active UC who did not respond to intravenous steroids nor sequential therapy. A response was obtained with ustekinumab and tofacitinib, 2 drugs widely used in adults but still with little evidence in children. Highlighting the important role of patients and their families helped decision-making, facilitating the work of the medical team. With multidisciplinary management and close follow-up, they have been able to avoid surgery entering complete clinical remission.
