    Echocardiographic Follow-up of Perinatally HIV-infected Children and Adolescents Results From a Single-center Retrospective Cohort Study in Brazil
    (2020) VALLILO, Nathalia Gaspar; DURIGON, Giuliana Stravinskas; LIANZA, Alessandro Cavalcanti; DINIZ, Maria de Fatima Rodrigues; SAWAMURA, Karen Saori Shiraishi; BRITO, Carolina Rocha; MARQUES, Heloisa Helena de Souza; FERRARO, Alexandre Archanjo; LEAL, Gabriela Nunes
    Background: The effects of HIV and antiretroviral therapy on cardiovascular system of perinatally infected children throughout their development are not fully understood. Objectives: To determine the prevalence of cardiac abnormalities in a retrospective cohort of perinatally HIV-infected patients and to investigate associations between echocardiographic and clinical data during their follow-up. Methods: Review of medical records and echocardiogram reports of 148 perinatally HIV-infected patients between January 1991 and December 2015. Results: Four hundred and eighty echocardiograms were analyzed and 46 (31%) patients showed cardiac abnormalities, frequently subclinical and transient. Nadir CD4 count was higher in patients with consistently normal echocardiogram: 263 (4-1480) versus 202 (5-1746) cells/mu L, P = 0.021. Right ventricular (RV) dilation was detected in 18.9%, left ventricular (LV) dilation in 21.6%, septal hypertrophy in 12.2%, LV posterior wall hypertrophy in 6%, LV systolic dysfunction in 8% and pulmonary hypertension in 8.7% of patients. Opportunistic infections were associated with RV dilation [odds ratio (OR = 4.34; 1.78-10.53; P < 0.01)], pulmonary hypertension (OR = 8.78; 2.80-27.51; P < 0.01) and LV systolic dysfunction (OR = 5.38; 1.55-18.71; P < 0.01). Longer duration of highly active antiretroviral therapy was associated with reduced risk of LV dilation (OR = 0.91; 0.85-0.97; P < 0.01) and systolic dysfunction (OR = 0.71; 0.59-0.85; P < 0.01). Protease inhibitors use was associated with reduced risk of RV dilation (OR = 0.54; 0.30-0.97; P < 0.05), LV dilation (OR = 0.35; 0.21-0.60; P < 0.01) and LV systolic dysfunction (OR = 0.07; 0.02-0.31; P < 0.01). Higher CD4 count was associated with lower risk of LV systolic dysfunction (OR = 0.82; 0.69-0.98; P < 0.05). Conclusions: Echocardiograms identified cardiac abnormalities among children with perinatally acquired HIV infection, and data suggest that immunologic status and therapeutic strategies throughout development can influence cardiac disease burden in this population.

    Impact of ERT and follow-up of 17 patients from the same family with a mild form of MPS II
    (2022) STEPHAN, Bruno de Oliveira; QUAIO, Caio Robledo; SPOLADOR, Gustavo Marquezani; PAULA, Ana Carolina de; CURIATI, Marco Antonio; MARTINS, Ana Maria; LEAL, Gabriela Nunes; TENORIO, Artur; FINZI, Simone; CHIMELO, Flavia Teixeira; MATAS, Carla Gentile; HONJO, Rachel Sayuri; BERTOLA, Debora Romeo; KIM, Chong Ae
    Background: Mucopolysaccharidosis type II, also known as Hunter syndrome, is a rare X-linked recessive disorder caused by deficiency of the lysosomal enzyme Iduronate-2-Sulfatase (IDS), leading to progressive accumulation of Glycosaminoglycans (GAGs) in several organs. Over the years, Enzyme Replacement Therapy (ERT) has provided significant benefits for patients, retarding the natural progression of the disease. Results: The authors evaluated 17 patients from the same family with a mild form of MPS type II; the proband had developed acute decompensated heart failure refractory to clinical measurements at 23 years and needed a rather urgent heart transplant; however, he died from surgical complications shortly after the procedure. Nevertheless, subsequent to his tragic death, 16 affected male relatives were detected after biochemical tests identifying the low or absent activity of the IDS enzyme and confirmed by molecular analysis of the IDS gene. Following diagnosis, different options of treatment were chosen: 6 patients started ERT with Elaprase (R) (Idursulfase) soon after, while the other 10 remained without ERT. Eventually, 4 patients in the latter group began ERT with Hunterase (R) (Idursulfase Beta). None presented adverse effects to either form of the enzyme. Among the 6 individuals without any ERT, two died of natural causes, after reaching 70 years. Despite the variable phenotype within the same family (mainly heart dysfunctions and carpal tunnel syndrome), all 14 remaining patients were alive with an independent lifestyle. Conclusion: Here, the authors report the variable progress of the disease with and without ERT in a large Brazilian family with a slowly progressive form of MPS II, harboring the same missense variant in the IDS gene.

    Mucopolysaccharidosis type VI: case report with first neonatal presentation with ascites fetalis and rapidly progressive cardiac manifestation
    (2020) HONJO, Rachel Sayuri; VACA, Evelyn Cristina Nunez; LEAL, Gabriela Nunes; ABELLAN, Deipara Monteiro; IKARI, Nana Miura; JATENE, Marcelo Biscegli; MARTINS, Ana Maria; KIM, Chong Ae
    Background The Mucopolysaccharidosis type VI (MPS VI), also known as Maroteaux-Lamy syndrome (OMIM 253200) is an autosomal recessive lysosomal disorder, caused by the deficiency of the enzyme N-acetylgalactosamine 4-sulfatase (also known as arylsulfatase B) due to mutations of the ARSB gene. Cardiologic features are well recognized, and are always present in MPS VI patients. Generally, the onset and the progression of the cardiologic symptoms are insidious, and just a few patients have developed a rapidly progressive disease. Cardiac involvement in MPS VI is a common and progressive feature. For MPS patients, cardiac evaluations are recommended every 1 to 2 years, including blood pressure measurement, electrocardiography and echocardiography. However, congestive heart failure and valvular surgical repair are not frequently seen, and if so, they are performed in adults. Here we report on an atypical MPS VI case with ascites fetalis and a rapidly progressive cardiac disease. Case presentation A 6-month-old Brazilian male, only child of a Brazilian healthy non-consanguineous couple. During pregnancy, second trimester ultrasonography observed fetal ascites and bilateral hydrocele. Physical exam at 6 months-old revealed a typical gibbus deformity and MPS was suspected. Biochemical investigation revealed a diagnosis of MPS type VI, confirmed by molecular test. Baseline echocardiogram revealed discrete tricuspid regurgitation and a thickened mitral valve with posterior leaflet prolapse, causing moderate to severe regurgitation. The patient evolved with mitral insufficiency and congestive heart failure, eventually requiring surgical repair by the first year of age. Conclusions We report the first case of MPS VI whose manifestations started in the prenatal period with fetal ascites, with severe cardiac valvular disease that eventually required early surgical repair. Moreover, in MPS with neonatal presentation, including fetal hydrops, besides MPS I, IVA and VII, clinicians should include MPS VI in the differential diagnosis.

    Heart function in juvenile idiopathic arthritis patients: A biventricular two-dimensional speckle-tracking echocardiography study
    (2022) LIANZA, Alessandro C.; LEAL, Gabriela N.; AIKAWA, Nadia E.; KOZU, Katia T.; DINIZ, Maria De Fatima R.; SAWAMURA, Karen S. S.; MENEZES, Carolina R. B.; MARTINS, Camila Lino; CAMPOS, Lucia M.; ELIAS, Adriana M.; SILVA, Clovis A.
    Objectives We evaluated cardiac function in juvenile idiopathic arthritis (JIA) patients by 2D speckle-tracking echocardiography (2DSTE) and to assess possible associations with clinical, laboratorial, and treatment data. Methods A group of 42 JIA patients and 42 healthy controls were evaluated using both conventional echocardiography and 2DSTE. JIA patients underwent clinical and laboratory assessment. Results Conventional echocardiography data demonstrated normal left ventricular (LV) ejection fraction in both groups (71 vs. 71%; p = .69). 2DSTE analysis demonstrated that JIA patients presented significantly lower LV global systolic longitudinal strain (LVGLS) (-18.76 vs. -22%; p < .0001), LV systolic strain rate (LVSSR) (1.06 vs. 1.32 s(-1); p < .0001), LV diastolic strain rate (LVDSR) (1.58 vs. 1.8 s(-1); p < .0137), right ventricular global systolic strain (RVGLS) (-24.1% vs. -27.7%; p = .0002), and right ventricular systolic strain rate (RVSSR) (1.4 vs. 1.8 s(-1); p = .0035). JIA patients under biological agents presented higher LVGLS (p = .02) and RVLS (p = .01). We also detected an association between LVGLS and C-reactive protein [CRP; -20% in normal CRP (10/42) vs. -18% in elevated CRP patients (32/42), p = .03]. Conclusions JIA patients present different echocardiographic status from healthy patients. Moreover, our data suggest that JIA patients under biological agents present association with better cardiac function as shown by strain analysis.

    Subclinical left ventricular dysfunction in childhood-onset systemic lupus erythematosus: a two-dimensional speckle-tracking echocardiographic study
    (2016) LEAL, G. N.; SILVA, K. F.; LIANZA, A. C.; GIACOMIN, M. F.; ANDRADE, J. L.; KOZU, K.; BONFA, E.; SILVA, C. A.
    Objectives: The main purpose of the study was to investigate left ventricular (LV) subclinical systolic and diastolic dysfunction in childhood-onset systemic lupus erythematosus (c-SLE) patients using two-dimensional speckle-tracking (2DST) echocardiography. We also interrogated possible correlations between impairment of myocardial deformation and the SLE Disease Activity Index 2000 (SLEDAI-2K), as well as the presence of traditional and disease-related cardiovascular risk factors (CRFs).Method: A total of 50 asymptomatic patients and 50 controls (age 14.74 vs. 14.82years, p=0.83) were evaluated by standard and 2DST echocardiography.Results: Despite a normal ejection fraction (EF), there was reduction in all parameters of LV longitudinal and radial deformation in patients compared to controls: peak longitudinal systolic strain (PLSS) [-20.3 (-11 to -26) vs. -22 (-17.8 to -30.4)%, p<0.0001], PLSS rate [-1.190.21 vs. -1.3 +/- 0.25s(-1), p=0.0005], longitudinal strain rate in early diastole [1.7 (0.99-2.95) vs. 2 (1.08-3.00) s(-1), p=0.0034], peak radial systolic strain [33.09 +/- 8.6 vs. 44.36 +/- 8.72%, p<0.0001], peak radial systolic strain rate [1.98 +/- 0.53 vs. 2.49 +/- 0.68s(-1), p<0.0001], and radial strain rate in early diastole [-2.31 +/- 0.88 vs. -2.75 +/- 0.97s(-1), p=0.02]. Peak circumferential systolic strain [-23.67 +/- 3.46 vs. -24.6 +/- 2.86%, p=0.43] and circumferential strain in early diastole [0.37 +/- 0.17 vs. 0.41 +/- 0.15, p=0.27] were similar between patients and controls, although peak circumferential systolic strain rate [-1.5 +/- 0.3 vs. -1.6 +/- 0.3s(-1), p=0.036] was reduced in c-SLE. Further analysis of patients revealed a negative correlation between LV PLSS and SLEDAI-2K (r= -0.52, p<0.0001), and also between LV PLSS and the number of CRFs per patient (r= -0.32, p=0.024).Conclusions: 2DST echocardiography has identified subclinical LV deformation impairment in c-SLE patients. Disease activity and cumulative exposure to CRFs contribute to myocardial compromise.

    Contraception for adolescents with chronic rheumatic diseases
    (2017) LOURENCO, Benito; KOZU, Katia T.; LEAL, Gabriela N.; SILVA, Marco F.; FERNANDES, Elisabeth G. C.; FRANCA, Camila M. P.; SOUZA, Fernando H. C.; SILVA, Clovis A.
    Contraception is an important issue and should be a matter of concern in every medical visit of adolescent and young patients with chronic rheumatic diseases. This narrative review discusses contraception methods in adolescents with juvenile systemic lupus erythematosus (JSLE), antiphospholipid syndrome (APS), juvenile idiopathic arthritis (JIA) and juvenile dermatomyositis (JDM). Barrier methods are safe and their use should be encouraged for all adolescents with chronic rheumatic diseases. Combined oral contraceptives (COC) are strictly prohibited for JSLE and APS patients with positive antiphospholipid antibodies. Reversible long-acting contraception can be encouraged and offered routinely to the JSLE adolescent patient and other rheumatic diseases. Progestin-only pills are safe in the majority of rheumatic diseases, although the main concern related to its use by adolescents is poor adherence due to menstrual irregularity. Depot medroxyprogesterone acetate injections every three months is a highly effective contraception strategy, although its long-term use is associated with decreased bone mineral density. COC or other combined hormonal contraceptive may be options for JIA and JDM patients. Oral levonorgestrel should be considered as an emergency contraception method for all adolescents with chronic rheumatic diseases, including patients with contraindication to COC.

    Report of a Large Brazilian Family With a Very Attenuated Form of Hunter Syndrome (MPS II)
    (2012) QUAIO, C. R. D. C.; GRINBERG, H.; VIEIRA, M. L. C.; PAULA, A. C.; LEAL, G. N.; GOMY, I.; LEISTNER-SEGAL, S.; GIUGLIANI, R.; BERTOLA, D. R.; KIM, C. A.
    Hunter syndrome, or Mucopolysaccharidosis type II (MPS II), is a rare X-linked recessive disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase (IDS). The phenotypic spectrum varies from severe to attenuated clinical forms. We report a large Brazilian family with 16 affected individuals exhibiting a very attenuated form of MPS II. Fourteen female carriers were also identified. Twelve affected male patients, whose ages ranged from 1 to 35 years, were examined. Molecular analysis showed a novel missense mutation (p.A77D) in the IDS gene, confirming the diagnosis. Nine of the family members presented some degree of heart damage, though only the proband became symptomatic and required heart transplantation. One 19-year-old adult and 1-year-old twin boys each had a normal echocardiogram. Short stature was found in two adults while macrocephaly was found in one; the remaining adults had anthropometric measures within normal range. All affected adults had normal cognitive development and were able to perform normal daily activities, except one who had mild learning disability. Two patients died due to natural causes beyond 70 years of age. The female carriers did not present any signs of disease. In this large family with a mild form of MPS II and variable degree of clinical manifestations, it is noteworthy that several affected individuals have remained asymptomatic even at advanced age and even without enzyme replacement therapy.

    Subclinical Pulmonary Hypertension in Childhood Systemic Lupus Erythematosus Associated with Minor Disease Manifestations
    (2017) ANUARDO, Pedro; VERDIER, Monica; GORMEZANO, Natali W. S.; FERREIRA, Gabriela R. V.; LEAL, Gabriela N.; LIANZA, Alessandro; FERREIRA, Juliana C. O. A.; PEREIRA, Rosa M. R.; AIKAWA, Nadia E.; TERRERI, Maria Teresa; MAGALHES, Claudia S.; APPENZELLER, Simone; SANTOS, Maria Carolina dos; SACHETTI, Silvana B.; LEN, Claudio A.; PILLEGGI, Gecilmara S.; LOTUFO, Simone; BONFA, Eloisa; SILVA, Clovis A.
    The aim of this study was to evaluate pulmonary hypertension (PH) in 852 childhood-onset systemic lupus erythematosus (cSLE) patients. This was a large multicenter study conducted in 10 Pediatric Rheumatology Services of So Paulo state, Brazil. PH was defined as systolic pulmonary artery pressure > 35 mmHg and/or measurement of the mean pulmonary artery pressure > 25 mmHg and/or diastolic pressure > 15 mmHg by transthoracic echocardiogram. Demographic data, clinical manifestations, disease activity score (SLEDAI-2K), disease damage score (SLICC/ACR-DI) and treatments were also evaluated. Statistical analysis was performed using Bonferroni correction (p < 0.002). PH was observed in 17/852 (2%) cSLE patients. Effort dyspnea occurred in 3/17, chest pain in 1/17 and right ventricle dysfunction in 3/17 cSLE patients. None had pulmonary thromboembolism or antiphospholipid syndrome. Further comparison between 17 cSLE with PH and 85 cSLE control patients without PH with similar disease duration [15 (0-151) vs. 15 (0-153) months, p = 0.448], evaluated at the last visit, revealed higher frequencies of fever (47 vs. 9%, p < 0.001), reticuloendothelial manifestations (41 vs. 7%, p < 0.001) and serositis (35 vs. 5%, p = 0.001) in the former group. Frequencies of renal and neuropsychiatric involvements and antiphospholipid syndrome, as well as the median of SLEDAI-2K and SLICC/ACR-DI scores, were comparable in both groups (p > 0.002). Normal transthoracic echocardiography was evidenced in 9/17 (53%), with median cSLE duration of 17.5 months (1-40) after PH standard treatment. PH was a rare manifestation of cSLE occurring in the first two years of disease. The majority of patients were asymptomatic with mild lupus manifestations. The underlying mechanism seemed not to be related to pulmonary thromboembolism and/or antiphospholipid syndrome.
