Contiguous ABCD1/ DXS1357E deletion syndrome (CADDS) is a rare deletion syndrome involving two contiguous genes on Xq28, ABCD1 and BCAP31 (formerly known as DXS1357E). Only nine individuals with this diagnosis have been reported in the medical literature to date. Intragenic loss-of-function variants in BCAP31 cause the deafness, dystonia, and cerebral hypomyelination syndrome (DDCH). Isolated pathogenic intragenic variants in ABCD1 are associated with the most common peroxisomal disorder, X-linked adrenoleukodystrophy (X-ALD), a single transporter deficiency, which in its more severe cerebral form is characterised by childhood-onset neurodegeneration and high levels of very-long-chain fatty acids (VLCFA). While increased VLCFA levels also feature in CADDS, the few patients described to date all presented as neonates with a severe phenotype. Here we report a tenth individual with CADDS, a male infant with dysmorphic facial features who was diagnosed through ultra-rapid whole genome sequencing (WGS) in the setting of persistent cholestatic liver disease, sensorineural hearing loss, hypotonia and growth failure and developmental delay. Biochemical studies showed elevated VLCFA and mildly reduced plasmalogens. He died at 7 months having developed pancreatic exocrine deficiency and interstitial lung disease, two features we propose to be possible extensions to the CADDS phenotype. We also review the genetic, phenotypic, and biochemical features in previously reported individuals with CADDS.
Heterozygous pathogenic variants in POLR1A, which encodes the largest subunit of RNA Polymerase I, were previously identified as the cause of acrofacial dysostosis, Cincinnati-type. The predominant phenotypes observed in the cohort of 3 individuals were craniofacial anomalies reminiscent of Treacher Collins syndrome. We subsequently identified 17 additional individuals with 12 unique heterozygous variants in POLR1A and observed numerous additional phenotypes including neurodevelopmental abnormalities and structural cardiac defects, in combination with highly prevalent craniofacial anomalies and variable limb defects. To understand the pathogenesis of this pleiotropy, we modeled an allelic series of POLR1A variants in vitro and in vivo. In vitro assessments demonstrate variable effects of individual pathogenic variants on ribosomal RNA synthesis and nucleolar morphology, which supports the possibility of variant-specific phenotypic effects in affected individuals. To further explore variant-specific effects in vivo, we used CRISPR-Cas9 gene editing to recapitulate two human variants in mice. Additionally, spatiotemporal requirements for Polr1a in developmental lineages contributing to congenital anomalies in affected individuals were examined via conditional mutagenesis in neural crest cells (face and heart), the second heart field (cardiac outflow tract and right ventricle), and forebrain precursors in mice. Consistent with its ubiquitous role in the essential function of ribosome biogenesis, we observed that loss of Polr1a in any of these lineages causes cell-autonomous apoptosis resulting in embryonic malformations. Altogether, our work greatly expands the phenotype of human POLR1A-related disorders and demonstrates variant-specific effects that provide insights into the underlying pathogenesis of ribosomopathies.

BACKGROUND: Primary Sjögren syndrome (pSS) is a chronic autoimmune disease with its main target being exocrine glands, and is the connective tissue disease more frequently associated with other autoimmune diseases. The aim of this study was to assess the frequency of another autoimmune rheumatic disease (ARD) developed in primary Sjögren syndrome (pSS) patients and to describe it's clinical, serological and histologic characteristics. MATERIALS AND METHODS: This is a retrospective cohort study. Data of patients with pSS diagnosis (American-European criteria 2002), included in the GESSAR database (Grupo de Estudio Síndrome de Sjögren, Sociedad Argentina de Reumatología) were analyzed. The development of a second ARD was registered during the follow up. RESULTS: 681 patients were included, 94.8% female. The mean age was 54 (SD 14) years and mean age at diagnosis of 50 (SD 13) years. The mean follow-up was 4.7 (SD 4.9) years; 30 patients (4.41%, CI 95%: 3.1-5.7) developed a second ARD during the follow up, incidence rate was 9.1/1000 patients-year (IR 95%: 5.8-12.4/1000 patients-year), the most frequent being rheumatoid arthritis (RA). 96% out of these 30 patients had xerophthalmia, 86.2% xerostomia, 92% positive Schirmer test, 88.24% positive Rosa Bengala test, lisamine green or Ocular Staining Score, 81.2% positive unstimulated salivary flow, 82.1% Ro(+) and 33.33% La(+). Minor salivary gland biopsy had been performed in 14 of the 30 patients, 12 with positive results. There were no statistically significant differences respect baseline characteristics when comparing the patients who developed another ARD to the ones that did not. CONCLUSIONS: Of all the patients analyzed, 4.4% presented another ARD during their follow-up. It is important to be aware of this, to make an early and proper diagnosis and treatment of our patients.

PURPOSE: Common diagnostic next-generation sequencing strategies are not optimized to identify inherited variants in genes associated with dominant neurodevelopmental disorders as causal when the transmitting parent is clinically unaffected, leaving a significant number of cases with neurodevelopmental disorders undiagnosed. METHODS: We characterized 21 families with inherited heterozygous missense or protein-truncating variants in CHD3, a gene in which de novo variants cause Snijders Blok-Campeau syndrome. RESULTS: Computational facial and Human Phenotype Ontology-based comparisons showed that the phenotype of probands with inherited CHD3 variants overlaps with the phenotype previously associated with de novo CHD3 variants, whereas heterozygote parents are mildly or not affected, suggesting variable expressivity. In addition, similarly reduced expression levels of CHD3 protein in cells of an affected proband and of healthy family members with a CHD3 protein-truncating variant suggested that compensation of expression from the wild-type allele is unlikely to be an underlying mechanism. Notably, most inherited CHD3 variants were maternally transmitted. CONCLUSION: Our results point to a significant role of inherited variation in Snijders Blok-Campeau syndrome, a finding that is critical for correct variant interpretation and genetic counseling and warrants further investigation toward understanding the broader contributions of such variation to the landscape of human disease.

Materials and methods: This is a retrospective cohort study. Data of patients with pSS diagnosis (American-European criteria 2002), included in the GESSAR database (Grupo de Estudio Síndrome de Sjögren, Sociedad Argentina de Reumatología) were analyzed. The development of a second ARD was registered during the follow up. Results: 681 patients were included, 94.8% female. The mean age was 54 (SD 14) years and mean age at diagnosis of 50 (SD 13) years. The mean follow-up was 4.7 (SD 4.9) years; 30 patients (4.41%, CI 95%: 3.1-5.7) developed a second ARD during the follow up, incidence rate was 9.1/1000 patients-year (IR 95%: 5.8-12.4/1000 patients-year), the most frequent being rheumatoid arthritis (RA). 96% out of these 30 patients had xerophthalmia, 86.2% xerostomia, 92% positive Schirmer test, 88.24% positive Rosa Bengala test, lisamine green or Ocular Staining Score, 81.2% positive unstimulated salivary flow, 82.1% Ro(+) and 33.33% La(+).

There were no statistically significant differences respect baseline characteristics when comparing the patients who developed another ARD to the ones that did not. Conclusions: Of all the patients analyzed, 4.4% presented another ARD during their follow-up. It is important to be aware of this, to make an early and proper diagnosis and treatment of our patients. Key points Patients with primary Sjögren's Syndrome may develop another connective tissue disease during follow-up. The most frequently connective tissue disease developed during follow-up in the population of patients with primary Sjogren's Syndrome studied was rheumatoid arthritis. It is important to be aware of this to make an early and proper diagnosis.
OBJECTIVES: In this observational, analytical, cross-sectional study we aimed to describe the impact of primary Sjögren's syndrome (pSS) on work productivity and activities of daily living (ADL) to assess the association between ADL impairment and clinical manifestations and to compare ADL impairment according to patients' socioeconomic condition. METHODS: Patients diagnosed with pSS attending 11 centres from Argentina were included. To evaluate work productivity and ADL impairment, a work productivity and activity impairment questionnaire (WPAI) was used. A multiple linear regression model was performed, considering deterioration on ADL due to health as a dependent variable, adjusted for potential confounders. RESULTS: 252 patients were included, 98.4% were women, with a mean age of 52.6 years (±14.8). The average percentage of time lost due to health was 15.7 hours (±30.1 95% CI: 9.6-21.9); the decrease in work productivity was 27.2 (±30.2 95% CI: 21.3-33.1), the total disability was 33.7 (±35.8 95% CI: 26.4-4) and ADL deterioration was 34.2 (±30.9. 95% CI: 30.4-38). In the multivariate analysis, xerostomia, arthritis and depression showed significant and independent association. The mean of ADL impairment was 38.2 (±30.7) in patients attending public centres versus 28 (± 30.6) in private centres, which was a statistically significant difference. CONCLUSIONS: We found a compromise in all WPAI domains. Arthritis, xerostomia and depression were associated significantly and independently with ADL impairment. Deterioration in ADL was greater in patients treated in public centres. Considering these aspects will allow a better understanding of patients who suffer from this disease.

Conclusión: Nuestro estudio sugiere un menor compromiso glandular en pacientes con SSp diagnosticados a menor edad, sin un patrón diferencial característico en cuanto al compromiso sistémico.
Objective: To describe and compare the clinical manifestations, in adult patients diagnosed with primary Sjögren's Syndrome at age less than or equal to 35 years versus those over 35 years of age. Materials and Methods: We analyzed the data of patients older than 18 years, with diagnosis of primary Sjögren's syndrome (American - European criteria 2002), included in the GESSAR database (Sjögren Syndrome Study Group of the Argentine Society of Rheumatology). Results: 665 patients were included. One hundred of them with an age at diagnosis less than or equal to 35 years and with a mean age at diagnosis of 29 + 4 years, 92% of them women. The average age at diagnosis of the group over 35 years was 54 + 11 years, 96% women. Statistically significant differences were found between less than or equal to 35 years vs over 35 years, in xerophthalmia (90.72% vs 95.64%, p: 0.04) and xeroderma (42.35% vs 57.36% , p: 0.03), and in the following domains of ESSDAI (EULAR Activity Index for primary Sjögren's syndrome): peripheral nervous system (4.05 vs 11.32, p: 0.03), respiratory (6% vs 15.40%, p: 0.01) and renal (6% vs 1.59%, p: 0.02). Conclusion: Our study suggests less glandular involvement in patients with pSS diagnosed at a younger age, without a characteristic differential pattern regarding systemic involvement.

INTRODUCCIÓN: El Educational Needs Assessment Tool-versión española (SpENAT) es un cuestionario autorreportado que evalúa las necesidades educacionales (NEd) con el fin de dar información adaptada y centrada en el paciente con artritis reumatoide (AR). Comprende 39 preguntas agrupadas en 7 dominios: Manejo del dolor, Movimiento, Sentimientos, Proceso de artritis, Tratamientos, Medidas de autoayuda y Sistemas de apoyo. OBJETIVOS: Evaluar las NEd en pacientes con AR mediante el SpENAT y determinar cuáles son las principales fuentes de información a las que consultan. MATERIAL Y MÉTODOS: Estudio multicéntrico, observacional, analítico, de corte transversal. Se incluyeron pacientes consecutivos≥18 años con diagnóstico de AR (ACR 87 y/o ACR-EULAR 2010). Se consignaron datos demográficos, nivel educativo, características de la enfermedad y medidas clinimétricas. Todos los pacientes completaron el SpENAT y fueron interrogados acerca de las fuentes a las que acuden para obtener información de su enfermedad. ANÁLISIS ESTADÍSTICO: Se describieron las características poblacionales. Se determinaron las NEd como porcentajes del puntaje máximo posible de cada dominio. Se compararon las necesidades por dominio según sexo, años de educación, tiempo de evolución, uso de biológico y capacidad funcional mediante test de Anova y las comparaciones de a pares con prueba t de Student y corrección de Bonferroni. Se determinó correlación entre los dominios con test de Spearman. Se comparó la edad según la fuente de información con la prueba t de Student. RESULTADOS: Se incluyeron 496 pacientes de 20 centros de todo el país. Se observaron mayores NEd en los dominios Movimiento, Sentimientos y Proceso de artritis. Los pacientes de mayor nivel educacional (>7 años) refirieron mayores NEd en los dominios Proceso de artritis y Medidas de autoayuda. Un mayor deterioro funcional (HAQ≥0,87) se asoció con unas mayores NEd en todos los dominios. Los pacientes con alta actividad mostraron mayores NEd que los pacientes en remisión en los dominios Manejo del dolor, Movimiento, Sentimientos, Tratamientos y Sistemas de apoyo, y que los pacientes con baja actividad en los dominios Medidas de autoayuda y Sistemas de apoyo. Todos los dominios del SpENAT mostraron correlaciones positivas entre sí (p < 0,0001), siendo las más importantes Manejo del dolor/Movimiento y Tratamientos/Proceso de artritis (r≥0,7). La fuente de información más consultada fue el reumatólogo (93,95%); quienes recurrían a Internet tenían una menor edad en promedio (p = 0,0004). CONCLUSIÓN: Los pacientes con AR manifestaron un gran interés por conocer más sobre su enfermedad. Un elevado deterioro funcional se asocia con mayores NEd. Los pacientes con alta actividad de la enfermedad presentan mayores NEd en casi todos los dominios. El médico reumatólogo es la principal fuente de información del paciente con AR
BACKGROUND: The SpENAT, a Spanish version of the Educational Needs Assessment Tool, is a self-completed questionnaire that assesses educational needs (ENs) with the purpose of providing tailored and patient-centered information. It consists of 39 questions grouped into the 7 following domains: Pain management, Movement, Feelings, Arthritic process, Treatments, Self-help measures and Support system. OBJECTIVES: The objective of the study was to describe the ENs of rheumatoid arthritis (RA) patients using the SpENAT and to determine the main sources of information consulted by these patients. MATERIAL AND METHODS: Multicenter, observational, cross-sectional study. We included consecutive patients≥18 years with diagnosis of RA (ACR 87/ACR-EULAR 2010). Sociodemographic data, disease characteristics and clinimetric properties were recorded. All patients completed the SpENAT and were asked about the sources employed to obtain information about their disease. STATISTICAL ANALYSIS: Population characteristics were described. ENs were determined as percentages of the highest possible score for each domain. Needs for each domain according to sex, years of education, disease duration, use of biologicals and functional capacity were analyzed by means of ANOVA, and bivariate comparisons were made with Student's t-test and the Bonferroni correction. Correlation between domains was determined with the Spearman correlation coefficient. We compared patients' age by source of information with Student's t-test. RESULTS: We included 496 patients from 20 centers across the country. More ENs were observed in the domains of Movement, Feelings and the Arthritic process. Patients with higher educational level (>7 years) reported more ENs in the Arthritic process and Self-help measure domains. A higher functional impairment (HAQ-A≥0.87) was associated with more ENs in every domain. Patients with high activity showed more ENs than those in remission in the domains of Pain management, Movement, Feelings, Treatments and Support system, as well as those with low activity in Self-help measures and Support system domains. All SpENAT domains showed positive correlations among each other (P<.0001), the most important being Pain management/Movement and Treatments/Arthritic process (r≥0.7). The source of information most frequently consulted was the rheumatologist (93.95%); those who made use of Internet were on average younger (P=.0004). CONCLUSION: RA patients were very interested about knowing more about their disease. High functional impairment was associated with more ENs. Patients with high disease activity had higher EN levels in almost every domain. The rheumatologist was the main source of information for the patient with RA

Objetivos: Determinar la frecuencia de enfermedades autoinmunes (EAI) en pacientes con Artritis Reumatoidea (AR) y comparar la frecuencia de EAI entre pacientes con AR y sin AR ni otra EAI reumatológica. Material y Métodos: Estudio multicéntrico, observacional, analítico, retrospectivo. Se incluyeron pacientes consecutivos con AR (ACR/EULAR 2010) y como grupo control pacientes con diagnóstico inicial de Osteoartritis primaria (OA). Resultados: Se incluyeron 1549 pacientes: 831 con AR (84% mujeres, edad media 55.2 años [DE 13.6]) y 718 con OA (82% mujeres, edad media 67 años [DE 11.1]). La frecuencia de EAI en el grupo AR fue del 22% (n=183). Estos presentaron mayor frecuencia de EAI reumatológicas (9.4 vs 3.3%, p< 0.001), y menor frecuencia de EAI no reumatológicas que aquellos con OA (15.3 vs 20.5, p=0.007). La EAI reumatológica más prevalente fue el Síndrome de Sjögren, el cual fue más frecuente en el grupo AR (87.2 vs 29.2%, p< 0,001). La frecuencia de EAI reumatológicas en los pacientes con AR fue mayor en la forma erosiva (11 vs 6.8%, p=0.048). Conclusión: La frecuencia de EAI en los pacientes con AR fue del 22%, en quienes predominaron las de etiología reumatológica mientras que, las no reumatológicas predominaron en pacientes con OA.
Objectives: To determine the frequency of autoimmune diseases (AID) in Rheumatoid Arthritis (RA) patients and to compare this frequency between patients with and without RA or other rheumatologic AID. Methods: Multicenter, observational, analytical, retrospective study. Consecutive patients with diagnosis of RA (ACR/EULAR 2010) were included. Patients with initial diagnosis of primary ostearthritis (OA) were used as control group. Results: A total of 1549 patients were included: 831 RA (84% women, mean age 55.2 [±13.6]) and 718 OA (82% women, mean age 67 [± 11.1]). The frequency of AID in the RA group was 22% (n=183). RA patients showed higher frequency of rheumatologic AID (9.4 vs 3.3%, p< 0.001), and lower frequency of non-rheumatologic AID than OA patients (15.3 vs 20.5%, p= 0.007). The most prevalent rheumatic AID was Sjögren's Syndrome, which was more frequent in the AR group (87.2 vs 29.2%, p<0.001). The frequency of rheumatologic AID in RA patients was higher in those with erosive RA (11 vs 6.8%, p=0.048). Conclusion: The frequency of AID in RA patients was 22%. Rheumatologic AID were more frequent in RA patients, whereas non-rheumatologic AID prevailed in OA patients.

El síndrome de Sjögren primario (SSp) afecta preferentemente al sexo femenino. Los informes sobre la evolución de los embarazos en estas pacientes son pocos y contradictorios. Objetivo: Describir las características del embarazo y su desenlace en mujeres con SSp, así como la morbilidad del recién nacido. Material y métodos: Se incluyeron pacientes con SSp que quedaron embarazadas luego del comienzo de los síntomas de dicha enfermedad. Se describieron las características clínicas y serológicas, los factores de riesgo y las comorbilidades maternas previas. Se detalló la evolución de cada embarazo, el desenlace y las características del recién nacido. Resultados: Se evaluaron 11 pacientes con 18 embarazos posteriores al inicio de síntomas: todas presentaban FAN+; 10 anti-Ro/SSA+ y 7 anti-La/SSB+. El promedio de edad en años al inicio de los síntomas fue de 24,9 (DE 6,9) y al momento del embarazo fue de 30,3 (DE 5,4). Hubo 13 embarazos previos al diagnóstico, reportándose solo un aborto espontáneo. Después de la presentación del SSp, se informaron: 2 partos prematuros, un oligoamnios, 2 roturas prematuras de membranas y 2 recién nacidos con bajo peso al nacer. Se halló un caso con bloqueo cardíaco congénito y otro con lupus cutáneo neonatal. Todas las mujeres con complicaciones obstétricas (6) presentaban Ac anti-Ro/SSA+, 5 con Ac anti-La/SSB+. Quienes no tuvieron complicaciones (5): 2 presentaban anti-Ro/SSA y anti-La/SSB+, y 2 solo anti-Ro/SSA. Conclusiones: Casi la mitad de los embarazos de las pacientes con SSp analizados presentaron alguna complicación no atribuible a otro factor distinto de su enfermedad de base
Primary Sjögren's syndrome (pSS) is a condition that predominantly affects women. Reports of pregnancy outcome in these patients are limited and contradictory. Objective: To describe pregnancy characteristics and outcomes and newborn morbidity in women with pSS. Material and methods: We included women with pSS who became pregnant after the onset of the symptoms of the disease. Clinical and serological characteristics, risk factors and previous maternal comorbidities are described. For each pregnancy in a woman with pSS, we recorded pregnancy course and outcome and newborn condition. Results: We assessed 11 patients with 18 pregnancies after the onset of pSS symptoms. All of them presented FAN +; 10 anti-Ro / SSA + and 7 anti-La / SSB +. The mean age in years at the onset of symptoms was 24.9 (SD 6.9) and at the time of pregnancy was 30.3 (SD 5.4). Thirteen pregnancies happened before the diagnosis, reporting only one miscarriage. Two preterm births, 1 case of oligohydramnios, 2 of premature membrane rupture and 2 low birthweight babies were reported after the onset of pSS symptoms. There was 1 newborn with congenital atrioventricular block and another with neonatal cutaneous lupus. All the women with pregnancy complications (n=6) had anti-Ro/SSA antibodies. Conclusions: Almost half of the pregnancies assessed in women with pSS were associated with complications not attributable to factors other than the disease

RESUMEN Objetivos: Describir la frecuencia de manifestaciones cutáneas extraglandulares en pacientes con síndrome de Sjögren primario. Determinar el perfil clínico y de laboratorio de los pacientes que presentan estas manifestaciones en comparación con aquellos que no las presentan. Materiales y métodos: Se analizaron los datos de los pacientes incluidos en la base GESSAR (Grupo de Estudio Síndrome de Sjögren de la Sociedad Argentina de Reumatología). Para la comparación entre grupos, los controles se seleccionaron en forma aleatoria con una relación casos: controles de 1:4. A su vez, se compararon los pacientes con púrpura con los controles. Resultados: Sesenta y siete (14,1%) de los 474 pacientes incluidos en la base de datos tuvieron manifestaciones cutáneas extraglandulares. De ellos, el 58% tuvo púrpura. La artritis, la neuropatía, el descenso de C3 y de C4, y la crioglobulinemia fueron estadísticamente más frecuentes en los casos en comparación con los controles; sin embargo, no se encontró asociación independiente con ninguna de estas variables. En lo que respecta a púrpura, la artritis, la neuropatía periférica, la anemia, el descenso de C3 y de C4, anti-La y crioglobulinemia fueron estadísticamente más frecuentes en comparación con los controles. Solo el descenso de C4 y la positividad de crioglobulinas se asociaron en forma independiente a la presencia de púrpura. Conclusión: El 14% de los pacientes presentaron manifestaciones cutáneas extraglandulares. La púrpura fue la manifestación más frecuente. Esta se asoció en forma independiente con el descenso de C4 y la presencia de crioglobulinas.
ABSTRACT Objectives: To describe the frequency of extra-glandular cutaneous manifestations in patients with primary Sjögren's syndrome. To determine the clinical and laboratory profile of patients who present with these manifestations compared to those who do not. Materials and methods: A study was made of patients included in GESSAR database (Sjögren Syndrome Society of Argentina Rheumatology Study Group) were analyzed. For the comparison between groups, the controls were randomly selected, with a case:control ratio of 1:4. Patients with purpura were compared with controls. Results: A total of 67 (14.1%) of the 474 patients included in the database had extra-glandular cutaneous manifestations. Of them, 58% had purpura. Arthritis, neuropathy, a decrease in C3 and C4 levels, and the presence of cryoglobulins, were statistically more frequent in cases compared to controls, although there was no independent association found with any of these variables. As regards purpura, arthritis, peripheral neuropathy, anaemia, decrease in C3 and C4, anti-La, and cryoglobulinemia were statistically more frequent compared to controls. Only the decrease in C4, and the presence of cryoglobulins were independently associated with the presence of purpura.
