- Natural history of 39 patients with Achondroplasia(2018) CERONI, Jose Ricardo Magliocco; SOARES, Diogo Cordeiro de Queiroz; TESTAI, Larissa de Cassia; KAWAHIRA, Rachel Sayuri Honjo; YAMAMOTO, Guilherme Lopes; SUGAYAMA, Sofia Mizuho Miura; OLIVEIRA, Luiz Antonio Nunes de; BERTOLA, Debora Romeo; KIM, Chong AeOBJECTIVES: To characterize the natural history of 39 achondroplastic patients diagnosed by clinical, radiological and molecular assessments. METHODS: Observational and retrospective study of 39 patients who were attended at a public tertiary level hospital between 1995 and 2016. RESULTS: Diagnosis was made prenatally in 11 patients, at birth in 9 patients and within the first year of life in 13 patients. The most prevalent clinical findings were short stature, high forehead, trident hands, genu varum and macrocephaly. The most prevalent radiographic findings were rhizomelic shortening of the long bones and narrowing of the interpediculate distance of the caudal spine. There was motor developmental delay in 18 patients and speech delay in 16 patients. The most common clinical intercurrences were middle ear dysfunction, sleep apnea, limb pain and obesity from 2 to 9 years of age. One patient was large for the gestational age but did not develop obesity. One patient developed hydrocephalus at 10 years old. The current age of the patients varies from 15 months to 36 years. The molecular study performed by Sanger sequencing of the common heterozygous mutation 1138G >A in FGFR3 was positive in all patients. Four cases were inherited, and 35 were sporadic (paternal age from 19 to 66 years). CONCLUSIONS: The diagnoses were made early based on clinical and radiographic findings. All cases were confirmed molecularly. Despite presenting a benign course, it is necessary to establish a systematic protocol for the surveillance of these patients due to the common clinical intercurrences.

Q.; MELONI, V. A.; BELANGERO, S. I.; CARVALHEIRA, G. G.; MELARAGNO, M. I.- Herpetiform keratitis and palmoplantar hyperkeratosis: warning signs for Richner-Hanhart syndrome(2017) SOARES, Diogo C.; STROPARO, Mariana N.; LIAN, Yu C.; TAKAKURA, Cristina Y.; WOLF, Sabrina; BETZ, Regina; KIM, Chong A.Richner-Hanhart syndrome (RHS, tyrosinemia type II) is a rare, autosomal recessive inborn error of tyrosine metabolism caused by tyrosine aminotransferase deficiency. It is characterized by photophobia due to keratitis, painful palmoplantar hyperkeratosis, variable mental retardation, and elevated serum tyrosine levels. Patients are often misdiagnosed with herpes simplex keratitis. We report on a a boy from Brazil who presented with bilateral keratitis secondary to RHS, which had earlier been misdiagnosed as herpes simplex keratitis.
conferenceObject Analysis of soluble mediators of promotion and suppression of the immune response in patients with the 22q11.2 deletion syndrome(2021) SOARES, Diogo; KIM, Chong; TORRES, Leuridan; DANTAS, Anelisa; NUNES, Natalia; MELARAGNO, Maria Isabel; CARNEIRO-SAMPAIO, Magda- CD4(+)CD25(high)Foxp3(+) Treg deficiency in a Brazilian patient with Gaucher disease and lupus nephritis(2016) MATTA, Marina Cadena; SOARES, Diogo Cordeiro; KERSTENETZKY, Marcelo Soares; FREITAS, Augustus Cesar Pinto; KIM, Chong Ae; TORRES, Leuridan CavalcanteGaucher Disease (GD) is a rare autosomal recessive disorder caused by the deficient activity of beta-glucocerebrosidase. GD is one of the lysosomal storage diseases with the most remarkable alterations in the immune system, and that may manifest clinically as autoimmune disorders and malignancy. We reported the immunological evaluation of a patient with GD and lupus nephritis. Decreased absolute values of T, and NK, and an inversion of CD4(+)/CD8(+) ratio, low levels of IgM and normal B cells were found when compared to reference values in a Brazilian population. Absence ofCD4(+)CD25(high)Foxp3(+) Treg and high levels of total NKT, iNKT cells and CD8(+) iNKT subsets were also observed when compared to the healthy control and GD patient without lupus nephritis. Treg subset and CD8(+) iNKT abnormalities might be involved in severe lupus nephritis in a GD patient. We conclude by emphasizing the importance of the immunological evaluation on early diagnosis of autoimmunity contributing to reduce mortality and morbidity of these patients.
conferenceObject Investigation of copy number variations as possible genetic modifiers in patients with the 22q11.2 deletion syndrome(2023) NUNES, Beatriz Carvalho; ZAMARIOLLI, Malu; DANTAS, Anelisa Gollo; SOARES, Diogo Cordeiro Queiroz; KIM, Chong Ae; MELARAGNO, Maria Isabel- Impact of early enzyme-replacement therapy for mucopolysaccharidosis VI: results of a long-term follow-up of Brazilian siblings(2016) FRANCO, J. F.; SOARES, D. C.; TORRES, L. C.; LEAL, G. N.; CUNHA, M. T.; HONJO, R. S.; BERTOLA, D. R.; KIM, C. A.Mucopolysaccharidosis type VI (MPS VI) is an autosomal recessive multisystem lysosomal storage disorder, which is characterized by the deficiency of the enzyme arylsulfatase B encoded by the ARSB gene. Treatment of this disease with enzyme-replacement therapy (ERT) improves the clinical status of and generates hope for MPS VI patients. However, only few reports on patients with MPS VI treated before 5 years of age have been published. Thus, the objective of this study was to compare the clinical parameters of two sisters affected by MPS VI who started ERT at different ages (9 years and 1 year 5 months, respectively) and to determine the most relevant clinical impacts of early treatment after 85 months of evaluation. The treatment was well tolerated by both siblings. ERT in the younger sibling resulted in increased growth, an improved 6-minute walk test, less coarse face, slower progression of cardiac valve disease, and the absence of compressive myelopathy compared to that in her older sister. On the other hand, the older sibling had typical MPS VI phenotypic features before the commencement of ERT. Corneal clouding, clawed hands, and progressive skeletal changes were observed in both siblings despite the treatment. Both siblings displayed reduced frequencies of upper respiratory infections and apnea indices. This study emphasizes that early diagnosis and treatment of MPS VI are critical for a better disease outcome and to enhance the quality of life for these patients.
- Clinical description of 41 Brazilian patients with oculo-auriculo-vertebral dysplasia(2016) PEGLER, José Roberto Mendes; SOARES, Diogo Cordeiro de Queiroz; QUAIO, Caio Robledo D’Angioli Costa; FERNANDES, Natalia; OLIVEIRA, Luiz Antonio Nunes de; HONJO, Rachel Sayuri; BERTOLA, Debora Romeo; KIM, Chong AeSUMMARY Objective: To describe the most prominent clinical features of a cohort of patients with oculo-auriculo-vertebral (OAV) dysplasia in Brazil. Method: A review of medical records of patients with diagnosis of OAV from 1990 to 2010 was performed in a medical genetics center. Results: 41 patients were included in the study. Their average age at diagnosis was 2y 10mo (34,4±48,8 months) and the female proportion was 53.7%. Mean maternal age at patient’s birth was 28.5y (min: 17, max: 46y) for mothers and 31.4y (min: 21, max: 51y) for fathers. Most patients (97.5%) had auricular involvement, with facial manifestation in 90.2%, spinal in 65.9%, ocular in 53.7%, 36.6% with cardiovascular involvement, 29.3% urogenital, and 17% of the cases with central nervous system (CNS) involvement. The classic OAV triad was present in only 34%. All patients except one had concomitant problems in other organs or systems. Conclusion: Since the diagnosis of OAV dysplasia relies only on a comprehensive medical evaluation, it is imperative that clinicians be aware of the most common presentation of the syndrome. Once suspected, every patient should undergo a complete medical evaluation of multiple systems including complementary exams. Treatment of these patients is based on surgical correction of malformations and rehabilitation.
