Oxandrolona no tratamento da lipodermatoesclerose: relato de caso / Oxandrolone for treatment of lipodermatosclerosis: case report

A lipodermatoesclerose é uma paniculite que se caracteriza por endurecimento e hiperpigmentação da pele envolvendo as panturrilhas, com a aparência de "garrafa de champanhe invertida". Muitas abordagens terapêuticas têm sido recomendadas, mas o uso de oxandrolona para essa finalidade foi pouco estudado até o momento. Relatamos um caso de lipodermatoesclerose aguda em uma mulher de 61 anos, com história prévia de tratamento cirúrgico para insuficiência venosa de membros inferiores. A paciente apresentava edema e lesões dolorosas e eritematosas com infiltração difusa, que acometiam principalmente a face posterior da panturrilha esquerda. Foi tratada inicialmente com estanozolol e pentoxifilina, com boa resposta. Devido à indisponibilidade do estanozolol, iniciou-se o uso de oxandrolona. Esse tratamento foi bem tolerado, resultando em redução significativa do edema, do eritema e da infiltração presentes nos membros inferiores, além de alívio da dor. A oxandrolona pode representar uma opção útil e segura no tratamento da lipodermatoesclerose aguda

Lipodermatosclerosis is a panniculitis characterized by hardening and hyperpigmentation of the skin involving the calves with an "inverted champagne bottle" appearance. Many therapeutic approaches have been recommended, but the use of oxandrolone for this purpose has been studied very little to date. We report a case of acute lipodermatosclerosis in a 61-year-old woman with a previous history of surgical treatment for venous insufficiency of the lower limbs. The patient presented with edema and painful, erythematous lesions with diffuse infiltration, mainly affecting the posterior aspect of the left calf. She was initially treated with stanozolol and pentoxifylline, with good response. Due to unavailability of stanozolol, she was put on oxandrolone. This treatment was well tolerated, reduced the intensity of edema, erythema, and infiltration in the lower limbs, effectively leading to pain relief. Oxandrolone may be a useful and safe treatment for patients with acute lipodermatosclerosis

Quantitative Evaluation of the First Order Creatine-Kinase Reaction Rate Constant in in vivo Shunted Ovine Heart Treated with Oxandrolone Using Magnetization Transfer 31P Magnetic Resonance Spectroscopy (MT-31P-MRS) and 1H/31P Double-Tuned Surface Coil: a Preliminary Study

PURPOSE: Children born with single ventricle physiology demonstrate poor growth rate and suffer from malnutrition, which lead to increased morbidity and mortality in this population. We assume that an anabolic steroid, oxandrolone, will promote growth in these infants by improving myocardial energy utilization. The purpose of this paper is to study the efficacy of oxandrolone on myocardial energy consumption in these infants. MATERIALS AND METHODS: We modeled single ventricle physiology in a lamb by prenatally shunting the aorta to the pulmonary artery and then postnatally, we monitored cardiac energy utilization by quantitatively measuring the first order reaction rate constant, kf of the creatine-kinase reaction in the heart using magnetization transfer 31P magnetic resonance spectroscopy, home built 1H/31P transmit/receive double tuned coil, and transmit/receive switch. We also performed cine MRI to study the structure and dynamic function of the myocardium and the left ventricular chamber. The spectroscopy data were processed using home-developed python software, while cine data were analyzed using Argus software. RESULTS: We quantitatively measured both the first order reaction rate constant and ejection fraction in the control, shunted, and the oxandrolone-treated lambs. Both kf and ejection fraction were found to be more significantly reduced in the shunted lambs compared to the control lambs, and they are increased in oxandrolone-treated lambs. CONCLUSION: Some improvement was observed in both the first order reaction rate constant and ejection fraction for the lamb treated with oxandrolone in our preliminary study.

Oxandrolone use in adult burn patients. Systematic review and meta-analysis

PURPOSE: This study is a systematic literature review and meta-analysis concerning the use of a testosterone synthetic analog, oxandrolone, and its use in severe adult burns. METHODS: Randomized prospective clinical studies, in English, Portuguese or Spanish, were sought on the following databases: MEDLINE, COCHRANE, EMBASE and LILACS. There was no restriction in relation to the publication date. RESULTS: This search produced 24 studies on MEDLINE and twelve articles were presented on the COCHRANE database .Sixteen were excluded due to the title not being related to this search or by including children. Of the eigth residual studies, after adaptation to the inclusion criteria, only four were selected. After analyzing the results, two were discarded since they did not present adequate patient characterization and the facts on these articles were analyzed differently from the others, hindering the meta-analysis. CONCLUSION: The analysis of the available data demonstrated significant benefits (p<0.05) considering lesser loss of corporal mass, lesser nitrogen loss, and shorter donor area healing time, when Oxandrolone was used, comparatively with the control group (placebo or not). .

Estatura final (EF) em síndrome de Turner (ST): experiência de 76 casos acompanhados na Unidade de Endocrinologia Pediátrica do Hospital de Clínicas da Universidade Federal do Paraná / Final height (FH) in Turner syndrome (TS): experience of 76 cases followed at the Pediatric Endocrinology Unit, Hospital de Clinicas, Federal University of Paraná

Objetivo: Relatar estatura final (EF) em 76 pacientes com síndrome de Turner (ST). Materiais e métodos: Revisão de prontuários e avaliação dos escores z: da estatura alvo (EA) e EF segundo o NCHS/CDC/2000 e da EF segundo Lyon e cols. Resultados: Pacientes foram classificados em três grupos: A (n = 16), tratamento com estrogênios e progestágenos; B (n = 21), tratamento com oxandrolona; C (n = 39), tratamento com hormônio de crescimento (GH) e oxandrolona. Não houve diferença no escore z da EA entre os grupos e no escore z da EF entre A e B. O escore z da EF do grupo C foi maior que o dos outros grupos, maior que 2 DP segundo Lyon e no percentil 3 da curva NCHS/CDC. Análise de regressão múltipla mostrou tipo de tratamento (p < 0,001) e estatura materna (p = 0,02) como fatores que mais influenciaram a EF. Conclusão: GH mais OX e estatura materna contribuíram significativamente para aumento da EF na ST.

Objective: To report the final height (FH) of 76 patients with Turner syndrome (TS). Materials and methods: Review of the files and calculation of z scores: of target height (TH), and FH according to NCHS/CDC/2000 and FH according to Lyon and cols. Results: Patients were classified in three groups: A (n = 16), treatment with estrogens and progestogens; B (n = 21), treatment with oxandrolone (OX); C (n = 39), growth hormone (GH) plus OX. The z score of TH was not different among the groups and z score of FH was not different between A e B. Z score of FH of group C was greater than the other groups, > 2SDS of Lyon's curve and fitted on the 3rd percentile of NCHS/CDC. Multiple regression analysis showed type of treatment (p < 0.001) and maternal height (p = 0.02) as most influencing factors on FH. Conclusion: GH plus OX and maternal height contributed significantly to enhance FH of TS patients.

Turner syndrome: searching for better outcomes

OBJECTIVES: To assess the results of growth hormone on the growth of girls with Turner Syndrome and identify relevant parameters to improve outcomes. METHODS: Growth velocity and final height were studied in a historical cohort of 41 girls, regularly followed up for hormone distribution at three referral centers. The influence of oxandrolone and of estrogens on the final height was analyzed. The girls (initial chronological age=8.9±3.4years; initial bone age=7.0±3.1years) used 0.19 mg/kg/week of growth hormone for 4.0 ± 2.0 years. RESULTS: In the first year, growth velocity increased by 71.5 percent in 41 girls and 103.4 percent in those who reached final height (11 girls). The whole group had a gain in the height SDS of 0.8 ± 0.7 (p<0.01) and for those who reached a final height of 1.0 ± 0.8 (p<0.01). Final height (143.6 ±6.3 cm) was 3.9 ± 5.3 cm higher than the predicted height, and the height gain occurred before estrogen therapy. Oxandrolone had no significant influence on height gain. The significant variables contributing to the final height were the duration of growth hormone used and its use prior to starting estrogens, the initial height SDS, and the growth velocity during the first year of treatment. CONCLUSIONS: We concluded that the use of growth hormone significantly increased the final height, which remained lower than the target. Results point to a need for starting growth hormone use as early as possible and to maximize treatment before estrogen replacement. It has been observed that even moderate doses of growth hormone may significantly increase early growth velocity.

Angioedema hereditário: considerações sobre terapia / Therapeutic approach of hereditary angioedema

OBJETIVOS: A primeira descrição clínica completa do angioedema hereditário (HAE) foi relatada por William Osler, em 1888. As formas de angioedema com deficiência de C1-INH são divididas em hereditárias e adquiridas. A terapêutica pode ser direcionada aos ataques agudos ou profilaxia de novos episódios. O tratamento de escolha é feito através de hormônios masculinizantes, podendo também ser indicado os inibidores da ativação do cininogênio e do plasminogênio como o ácido tranexâmico ou o ácido e-aminocapróico e a reposição de concentrado de C1-INH. O presente estudo relata a evolução de 10 pacientes (quatro famílias) acometidos por HAE e as peculiaridades do tratamento utilizado em cada caso. MÉTODOS: Dez pacientes (1-38 anos) com HAE foram diagnosticados através de história clínica e exames laboratoriais. Os testes realizados para avaliação do sistema complemento foram: dosagem sérica de C1-INH, C4 e C3 e ensaio hemolítico (CH50 e APH50) para as vias clássica e alternativa. O tratamento foi indicado de acordo com a gravidade dos sintomas, idade, sexo e resposta terapêutica. RESULTADOS: A avaliação clínica evidenciou 4/10 pacientes com edema subcutâneo recorrente; 3/10 pacientes com edema de laringe prévio e 3/10 pacientes com sintomas esporádicos. Sintomas de gravidade diferentes foram evidenciados na mesma família. A avaliação laboratorial (dosagem sérica) demonstrou: níveis de C1-INH diminuídos em 10/10; níveis diminuídos de C4 8/10; níveis indetectáveis de CH50 em 3/10 e diminuídos em 6/10; níveis diminuídos de APH50 em 2/10. 6/10 pacientes não receberam tratamento específico, sendo que dois deles apresentam alto risco para asfixia; uma adolescente tem sido controlada com ácido e-aminocapróico, uma criança que fazia uso de danazol passou a receber ácido tranexâmico, uma paciente de 30 anos recebe oxandrolona e um homem de 38 anos está em tratamento com danazol. CONCLUSAO: Apesar do HAE ser causado pelo mesmo defeito e acometer membros da mesma família, diferentes critérios têm sido estabelecidos para o tratamento desses pacientes. Foram indicados diferentes esquemas terapêuticos para HAE e alguns dos pacientes puderam ser seguidos sem terapia medicamentosa.

Final Adult Height in Patients with Turner Syndrome / 대한소아내분비학회지

PURPOSE: Short stature is the most constant finding in Turner syndrome. Short stature in Turner syndrome has lately received considerable attention, mostly because of recent attemp to improve growth by hormonal treatments; growth hormone, oxandrolone, estrogen. The aim of this study was to find out whether growth promoting treatment would improve final height in girls with Turner syndrome. METHODS:Seventy-one girls with the clinical chracteristics Turner syndrome verified by karyotype analysis were entered into this study. The following selection criteria for final adult height were used; Chronological age of more than 14years old, bone age of more than 15years old and growth velocity of less than 0.5cm per 6months. Analysis was performed by means of multiple regression analysis between descriptive data; modality of treatment with oxandrolone and/or estrigen, parental height, karyotype and final adult height. RESULTS: 1) The final adult height of untreated Turner syndrome was 138.9+/-3.9cm. 2)The final adult height in 29 GH treated Turner girls was 143.9+/-6.5cm, significant higher value than 42 GH untreated Turner girls height, 139.8+/-5.2cm(p<0.01). 3) The final height in GH only group and combined group were 141.2+/-6.0cm, 146.2+/-6.2cm, respectively. The combined therapy was more effective than GH therapy(p<0.01). 4) The final height in 32 patients with karyotype of 45,X was 141.6+/-5.6cm, and that of 31 structural aberration group was 140.3+/-6.2cm. There was no significant difference between two groups. But in mosaicism, only numeric abnormalities, the final height 145.9+/-6.1cm was much more higher than other two groups(p<0.05). 5) The final adult height in Turner syndrome was in good correlation with target height. Final adult height(cm)= 1.01*Target height(cm)- 4.97 r=0.51, p<0.05. 6) There was positive correlation between final adult height and height SDS at start GH treatment and negative correlation with age at start GH treatment. The delta height (final height - height at start treatment) correlate with GH treatment duration. CONCLUSIONS:The final adult height in Turner syndrome in a given ethinic or national population varies in the same way as adult height in normal women. Growth hormone therapy may increase final height in Turner syndrome irrespective of ethinic or national difference. Further growth was observed in GH combined with estrogen or oxandrolone.
