RESUMO

A transgender person has a gender identity opposite to the sex assigned at birth. Transgender individuals may have altered sexual function (SF) due to psychosocial factors related to body image distortion, shame, and dissatisfaction with genital appearance, and these conditions can increase the risk of sexual dysfunction. This study aimed to characterize the SF of trans-women after gender affirming surgery (GAS). We reviewed the Pubmed database for studies published between January 2008 and December 2021. 17 studies were included, four were cross-sectional studies, one prospective study, four prospective cohort studies, five retrospective studies. The instruments used to evaluate the SF were female sexual function index, semistructured questionnaires, patients' opinion, Sexual Desire Inventory, Maudsley Marital Questionnaire-S, WHOQOL-100. The results of our review indicate there is weak evidence that GAS improves the SF of trans-women. We thus recommend that future studies use questionnaires that are validated for the assessment of the SF of trans-women to better determine the impact of genital surgery in this population.

RESUMO

INTRODUCTION AND HYPOTHESIS: Hyperandrogenism in women with polycystic ovary syndrome (PCOS) could increase muscle mass and thereby pelvic floor muscle (PFM) strength, reducing the risk of urinary incontinence (UI). The aim of the present study was to assess PFM strength and UI among hyperandrogenic women with PCOS and a control group for comparison. METHODS: This is an observational, cross-sectional, case-control study. Seventy-nine women, aged 18 to 40 years with a mean body mass index (BMI) of 23.4 kg/cm(2) were recruited at the University Hospital: PCOS (n = 36) and control group for comparison (n = 43). All PCOS women had clinical and/or laboratory hyperandrogenism (> 80 ng/dL) and control women had regular menstrual cycles. PFM strength was assessed by vaginal manometry. The International Consultation on Incontinence Questionnaire of Urinary Incontinence Short Form (ICIQ-UI SF) was used to assess UI. Descriptive analysis, analysis of variance (ANOVA) and Fisher's exact test were used for statistical analyses. RESULTS: There was no statistically significant difference in mean PFM strength between the PCOS and the control group: 2.7 cm H2O (95% CI -6.2-11.6) p = 0.55. The prevalence of UI was 18.6% in the control group compared with 0% in the PCOS group p < 0.01. CONCLUSIONS: Women with PCOS showed absence of UI, but PFM strength did not differ from the control group.

RESUMO

Breaking bad news is common in obstetrics and gynecology (ob-gyn). However, it is difficult, and few doctors receive training on how to deal with this situation. This narrative review aims to gather, analyze, and synthesize part of the knowledge on the area, focused on Ob-Gyn. Among the 16 selected articles, two are randomized controlled intervention studies, and most studies refer to obstetrics. The results found by us pointed out that simulation, feedback/debriefing, lectures, and protocols could improve doctors' performance in communicating bad news. For patients, the context and how the information is transmitted seem to impact more than the content of the news. Ob-Gyn doctors could benefit from specific protocols and education, given the specialty's particularities. There is a lack of evidence about the most effective way to conduct such training. Finding validated ways to quantify and classify studies' results in the area, which would allow for the objective analysis of outcomes, is one of the biggest challenges concerning this topic.


Dar más notícias é comum em obstetrícia e ginecologia. Porém, é difícil e poucos médicos recebem treinamento sobre como lidar com essa situação. Esta revisão narrativa tem como objetivo reunir, analisar e sintetizar parte do conhecimento sobre a área, com foco na obstetrícia. Dentre os 16 artigos selecionados, dois são estudos de intervenção randomizados e controlados, e a maioria dos estudos refere-se à obstetrícia. Os resultados encontrados ressaltaram que simulação, feedback/entrevistas, palestras e protocolos podem melhorar o desempenho dos médicos na comunicação de más notícias. Para os pacientes, o contexto e como as informações são transmitidas parecem ter maior impacto do que o conteúdo das notícias. Os obstetras e ginecologistas poderiam se beneficiar de cursos e protocolos específicos, dadas as particularidades da especialidade. Faltam evidências sobre a forma mais eficaz de realizar esse treinamento. Encontrar formas validadas de quantificar e classificar os resultados dos estudos na área, permitindo uma análise objetiva dos resultados, é um dos maiores desafios neste tema.

RESUMO

INTRODUCTION: The sexual response depends on the adequate function of all systems related to the genital and extra-genital organs. Physiological conditions such as menopause can interfere with sexual expression because of central and peripheral changes. Genital effects of estrogen include vaginal trophism, lubrication, and local pleasure sensation in the sexual arousal phase. Hypoestrogenism causes changes in the four layers of the vaginal wall that may result in dyspareunia and a loss in the quality of the genital arousal response. AIM: The purpose of this review is to highlight the changes in the vaginal wall caused by hypoestrogenism, its possible relationship with dyspareunia, and its repercussions for genital arousal. Treatments for hypoestrogenism are also discussed. METHODS: We evaluated the data available in PubMed (1982-2008) and surveyed the reference list for relevant studies. Two reviewers analyzed the data independently. A study was considered to be of high quality if it had all three of the following characteristics: (i) prospective design; (ii) valid data; and (iii) adequate sample size. Reviews and experimental animal studies were also considered. MAIN OUTCOME MEASURES: Normal genital morphology, hypoestrogenism and hormone replacement therapy were the focus of the studies reviewed in this paper. RESULTS: Atrophy of the vaginal wall may be associated with dyspareunia and genital sexual arousal disorder, but psychological and sociocultural aspects must also be considered. Regardless, however, local estrogen therapy is useful in improving vaginal wall trophism and, thus, in improving the sexual response. CONCLUSIONS: There are many possible alterations in the structure of the vaginal wall that are related to estrogen deficiency that may require medical intervention beyond the usual strategies used to attain adequate sexual function. Physicians should attempt to treat these alterations, and more research is needed to elucidate the physiopathology of dyspareunia and genital sexual arousal physiology.

RESUMO

BACKGROUND: Cultural, social, physiological and psychological factors may alter the course of sexual function in climacteric women. OBJECTIVE: The objective of the present literature review is to survey the prevalence of sexual dysfunctions in the climacteric and to establish the association between the organic and psychic changes that occur during this phase and sexual dysfunction. We also discuss potential treatments. METHODS: We evaluated the data available in PubMed (1982-2008). For each original article, two reviewers analyzed the data independently and considered a study to be of high quality if it had all three of the following characteristics: prospective design, valid data and adequate sample size. Both reviewers extracted data from each of the 99 studies selected: 34 cross-sectional studies, 25 cohort studies, 9 trials, 31 reviews related to sexuality in pre- and post-menopausal women. RESULTS: Sexual dysfunction among climacteric women is widespread and is associated with bio-psychosocial factors. However, there is not enough evidence to correlate sexual dysfunction with a decrease in estrogen levels and biological aging. A strong association exists between climacteric genital symptoms and coital pain. There is, however, sufficient evidence demonstrating the benefits of local estrogen therapy for patients with genital symptoms. CONCLUSION: A significant decline in sexual function occurs in climacteric women, although it is still unclear whether this is associated with the known decrease in estrogen levels or with aging, or both. Relational factors may interfere with sexual function during this phase. The climacteric genital symptoms improve with estrogen replacement therapy, and positively influence sexual function. Further studies are needed to establish the actual impact of the decrease in estrogen levels and of aging on the sex life of climacteric women.

RESUMO

BACKGROUND & AIMS: Women with polycystic ovary syndrome (PCOS) have greater predisposition to obesity, but the mechanisms are still unknown. Hyperinsulinemia, insulin resistance and low levels of ghrelin are common in this group. For the purposes of the present study, it was assumed that such changes could have an influence on hunger. This study aimed to assess the hunger pattern before and after an ad libitum meal and the association between insulin and plasma ghrelin with hunger perception in women with obesity, with and without PCOS. METHOD: This cross-sectional study included 53 women with obesity, 30 with PCOS, and 23 controls (with obesity but without PCOS). Insulin, ghrelin, glucose and subjective ratings of hunger (by 100 mm visual analogue scales) were analyzed in a fasting state, preprandially at 12:00 before the ad libitum meal, and postprandially 15, 45, 75 and 135 min after the beginning of the ad libitum meal. RESULTS: There was a significant increase in hunger one hour after the beginning of the ad libitum meal (75 min) in the PCOS group (p = .01) compared to 15 min, whereas this only occurred after 135 min in the control group (2 h later). The usual energy intake adjusted by the intra-individual variability was higher in the PCOS group than in the control group (2309 ±â€¯461 kcal·d-1 × 2124 ±â€¯480 kcal·d-1; p = .04). The concentrations of insulin and ghrelin, in both preprandial and postprandial periods, were not associated with the perception of hunger. CONCLUSIONS: Women with obesity and PCOS had an earlier return of hunger in the postprandial period after an ad libitum meal, but there was not associated with postprandial ghrelin and insulin levels.

RESUMO

UNLABELLED: The correlation of prolactin (PRL) levels with SLE activity is a controversial issue, which could be explained by the presence of macroprolactin (MPRL), a high molecular weight form of PRL with a lower in vivo biological activity. OBJECTIVES: We aimed to evaluate the prevalence of hyperprolactinemia, PRL and MPRL levels in SLE patients, and to correlate these levels with disease activity as measured by the SLE Disease Activity Index (SLEDAI). MATERIAL AND METHODS: We conducted a case-control, cross-sectional study with 73 SLE patients (L group), sixty-two of which were evaluated before and after treatment, and correlated the results with serum PRL and MPRL levels. These results were compared to those of 29 healthy women with ovulatory cycles (C group) and 34 women in the third trimester of pregnancy (G group). RESULTS: Mean PRL levels were: 8,8 ng/ml on C group; 12,0 ng/ml on L group (p = 0.02) and 158,5 ng/ml on G group. Hyperprolactinemia was present in 19.4% of SLE patients, but was not found on C group. The MPRL form was predominant among 20.5% of SLE patients, in none of the C group and in only 5.8% of pregnant women. There was a strong correlation between the PRL levels and SLE activity, regardless of the hormone's molecular form. SLE treatment was able to reduce levels of all forms of PRL. The predominance of MPRL, however, did not change after treatment. CONCLUSIONS: Despite its lower biological activity, MPRL levels correlated with LES activity as much as free prolactin.

RESUMO

PURPOSE: This study investigated the effects of progressive resistance training (PRT) on lean muscle mass (LMM) in women with or without polycystic ovary syndrome (PCOS) and its effects on metabolic factors and concentrations of related steroid hormones. DESIGN: This was a nonrandomized, therapeutic, open, single-arm study. PARTICIPANTS: All in all, 45 sedentary women with PCOS and 52 without (non-PCOS), 18-37 yr of age, with body mass indexes (BMI) of 18-39.9 kg·m(-2) of all races and social status, performed PRT three times a week for 4 months. Before and after PRT, the concentrations of hormones and metabolic factors and waist circumference were measured. LMM and total body fat percentage were determined using dual-energy x-ray absorptiometry. Clinical characteristics, LMM, and fasting glucose were adjusted for confounding covariables and compared using general linear mixed models. Each patient's menstrual history was taken before study enrollment and after PRT. RESULTS: PRT resulted in reduced plasma testosterone and fasting glucose levels. After PRT, the androstenedione concentration increased and the sex hormone-binding globulin concentration decreased in women with PCOS. The waist circumference was reduced (P < 0.01) and the muscle mass index, lean mass (LM)/height2, increased in women with PCOS (P = 0.04). Women with PCOS showed increased muscle mass indexes of appendicular LM/height2 (P = 0.03) and LM/height2 (P < 0.01) compared with the baseline. Total LM and trunk LM were elevated in women with PCOS (P = 0.01) at the baseline and after PRT. CONCLUSION: To our knowledge, this is the first report to show that resistance exercise alone can improve hyperandrogenism, reproductive function, and body composition by decreasing visceral fat and increasing LMM, but it has no metabolic impact on women with PCOS.

RESUMO

Obese women with polycystic ovary syndrome (PCOS) may have impairment in the regulation of food intake associated with ghrelin and insulin. In order to compare postprandial ghrelin and insulin responses to an ad libitum meal, we assessed 30 obese women with PCOS and 23 obese women without PCOS (control group). Blood samples were taken under fasting conditions, preprandially, and 15, 45, 75, and 135 minutes after the beginning of an ad libitum meal and ghrelin and insulin concentrations were analyzed. Insulin resistance (IR) was classified using basal insulin, quantitative insulin sensitivity check index, and homeostasis model assessment index. Mean ad libitum food intake was similar between the groups (468 ± 150 vs 444 ± 165 g, P = .60). The IR was found in 56.6% in PCOS group compared with 30.4% in the control group (P < .01). The postprandial ghrelin response was similar in both the groups but the insulin area under the curve (AUC) tend to be greater in the PCOS group (12807 ± 8149.4 vs 8654.4 ± 7232.3 µIU/mL/min; P = .057). The ghrelin AUC was negatively correlated with the insulin AUC (r = -.5138; P = .01) only in the control group. The imbalance in the feedback mechanisms between insulin and ghrelin, present in obese women, especially those with IR, may affect food intake throughout the day and that could be a mechanism for the development of obesity in PCOS.

RESUMO

PURPOSE: To characterize patients with indeterminate values of hyperprolactinemia (PEG test for the identification of macroprolactinemias with recovery between 30 and 65%) (PRLi) or macroprolactinemia (PRLm), in relation to clinical characteristics, such as the presence or absence of symptoms, as well as their intensity and variation, and the presence or absence of central nervous system tumors. METHODS: This is a cross-sectional retrospective survey of records of 24 patients with hyperprolactinemia, in reproductive ages, with prolactin >25 ng/dL. Eleven women with PRLm and 13 with PRLi were included. Records from the two groups were extracted for analysis: age, parity, body mass index, presence of galactorrhea, infertility, and central nervous system tumor. Anthropometrics data were expressed as mean and standard deviation. To compare groups regarding the presence of central nervous system tumor, galactorrhea, as well as infertility we used the Student's t-test. RESULTS: Galactorrhea was more prevalent in patients with PRLi (p=0.01). Seventy percent of women with PRLi presented pituitary tumor (microprolactinoma), whereas this finding was evident in 17% of the PRLm Group (p=0.04). Among the patients with and PRLm PRLi, nine were not investigated with the image of the central nervous system because they have low levels of prolactin (five carriers and four PRLm PRLi). There were no significant differences regarding the occurrence of infertility or irregular menstrual cycles between groups. DISCUSSION: Women with intermediate hyperprolactinemia present more galactorrhea symptoms as well as central nervous system tumors than women with macroprolactinemia.

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is an endocrine disorder associated with metabolic dysfunction and changes in cardiovascular risk markers, and using oral contraceptives (OCs) may exert a further negative effect on these alterations in patients with PCOS. Thus, the primary objective of this study was to assess the effects on arterial function and structure of an OC containing chlormadinone acetate (2 mg) and ethinylestradiol (30 mcg), alone or combined with spironolactone (OC+SPL), in patients with PCOS. STUDY DESIGN: This was a randomized, controlled clinical trial. Fifty women with PCOS between 18 and 35 years of age were randomized by a computer program to use OC or OC+SPL. Brachial artery flow-mediated vasodilation, carotid intima-media thickness and the carotid artery stiffness index were evaluated at baseline and after 6 and 12 months. Serum markers for cardiovascular disease were also analyzed. The intragroup data were analyzed using analysis of variance with Tukey's post hoc test. A multivariate linear regression model was used to analyze the intergroup data. RESULTS: At 12 months, the increase in mean total cholesterol levels was greater in the OC+SPL group than in the OC group (27% vs. 13%, respectively; p=.02). The increase in mean sex hormone-binding globulin levels was greater in the OC group than in the OC+SPL group (424% vs. 364%, respectively; p=.01). No statistically significant differences between the groups were found for any of the other variables. CONCLUSION: The addition of spironolactone to an OC containing chlormadinone acetate and ethinylestradiol conferred no cardiovascular risk-marker advantages in young women with PCOS.

RESUMO

Abstract Objectives To assess the prevalence of hypovitaminosis D, altered arterial blood pressure, and serum levels of glucose and lipids in community-dwelling women in the city of Ribeirão Preto, in the southeast of Brazil. Methods Thiswas a cross-sectional studyof women aged40-70years old.Calciumintake and level of sun exposure were assessed by means of a questionnaire. A blood sample was used to determine glucose, lipid profile and 25-hydroxyvitaminD(25[OH]D) concentration. Results Ninety-one women were enrolled (age = 54.2 ± 7.1 years). Themean serum 25(OH)D concentration was 25.7 ± 8.9 ng/mL. A total of 24 (26.4%) women had 25 (OH)D levels < 20 ng/mL. Seventy women (76.9%) had 25(OH)D levels < 30 ng/mL. Seventy-five women (90.4%) had inadequate calcium intake, and 61 women (67%) had appropriate sun exposure, 49 of whom (80.3%) had serum 25(OH)D levels < 30 ng/mL. Conclusion This study indicates that even in community-dwelling women, living in a city with high sun exposure, serum levels of 25(OH)D > 30 ng/ml are hardly reached. Thus, it is probable that other intrinsic factors besides sun exposure may regulate the levels of vitamin D.


Resumo Objetivos Estimar a prevalência de hipovitaminose D, hipertensão arterial, e níveis séricos de glicose e perfil lipídico em uma comunidade de mulheres de Ribeirão Preto, no Sudeste brasileiro. Métodos Estudo transversal com mulheres de 40 a 70 anos de idade, submetidas a um questionário para determinar ingestão diária de cálcio e nível de exposição solar, e coleta de sangue para determinar glicose, perfil lipídico e concentração de 25- hidroxivitamina D (25[OH]D). Resultados Noventa e uma mulheres foram incluídas (idade = 54,2 ± 7,1 anos). O nível sérico médio de 25(OH)D foi 25,7 ± 8,9 ng/mL. Um total de 24 (26,4%) mulheres teve níveis de 25(OH)D < 20 ng/mL. Setenta mulheres (76.9%) tiveram níveis de 25 (OH)D < 30 ng/mL. Setenta e uma mulheres (90.4%) tiveram uma ingesta inadequada de cálcio e 61 mulheres (67%) tiveram exposição solar adequada; 49 das quais (80.3%) tiveram níveis séricos de 25(OH)D < 30 ng/mL. Conclusão Este estudo indica que mesmo morando em uma cidade com exposição solar adequada, níveis séricos de 25(OH)D > 30 ng/mL dificilmente são atingidos por mulheres climatéricas. Logo, é provável que outros fatores intrínsecos podem regular o nível de vitamina D.

RESUMO

BACKGROUND: The purpose of this study was to evaluate the effect of long-term use of oral contraceptives (OC) containing 0.20 mg of ethinylestradiol (EE) combined with 0.15 mg of gestodene (GEST) on the peak aerobic capacity and at the anaerobic threshold (AT) level in active and sedentary young women. STUDY DESIGN: Eighty-eight women (23+/-2.1 years old) were divided into four groups - active-OC (G1), active-NOC (G2), sedentary-OC (G3) and sedentary-NOC (G4) - and were submitted to a continuous ergospirometric incremental test on a cycloergometer with 20 to 25 W min(-1) increments. Data were analyzed by two-way ANOVA with Tukey post hoc test. Level of significance was set at 5%. RESULTS: The OC use effect for the variables relative and absolute oxygen uptake VO(2) mL kg-(1) min(-1); VO(2), L min(-1), respectively), carbon dioxide output (VCO(2), L min(-1)), ventilation (VE, L min(-1)), heart rate (HR, bpm), respiratory exchange ratio (RER) and power output (W) data, as well as the interaction between OC use and exercise effect on the peak of test and at the AT level did not differ significantly between the active groups (G1 and G2) and the sedentary groups (G3 and G4). As to the exercise effect, for all variables studied, it was noted that the active groups presented higher values for the variables VO(2), VCO(2), VE and power output (p<.05) than the sedentary groups. The RER and HR were similar (p>.05) at the peak and at the AT level between G1 vs. G3 and G2 vs. G4. CONCLUSIONS: Long-term use of OC containing EE 0.20 mg plus GEST 0.15 mg does not affect aerobic capacity at the peak and at the AT level of exercise tests.

RESUMO

OBJECTIVE: To determine the influence of the use of tibolone on the frequency of flares of systemic lupus erythematosus (SLE) in postmenopausal patients. METHODS: Thirty patients with inactive or controlled SLE were included in the study. Patients were randomized to receive a 12-month course of either tibolona (2.5 mg/day) or placebo. The following were investigated: hypoestrogenism symptoms by Kupperman index, weight; anti-dsDNA antibodies; SLE flares (frequency) assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI); and biochemical profile (total cholesterol, high-density lipoprotein cholesterol [HDL-C], triglycerides, complement components [C3/C4], alpha1-acid glycoprotein, urea, creatinine, 24-h proteinuria, C-reactive protein and erythrocyte sedimentation rate). RESULTS: The reduction in Kupperman index was greater in the patients using tibolone than in those using placebo. The mean SLEDAI was not different between the groups during the study as well as SLE flare frequency (tibolone: 2/15 [13.3%] vs. placebo: 1/15 [6.7%]; p=0.54). All cases of flares were considered mild to moderate. Although the groups were similar at the baseline evaluation, after 6 and 12 months of treatment lower values were found in the tibolone group for triglycerides (6 months: 161.6+/-30.9 mg/dl vs. 194.4+/-46.5; p=0.04; 12 months 163.7+/-29.8 mg/dl vs. 204.1+/-49.9 mg/dl; p=0.02; tibolone vs. placebo group, respectively) and for HDL-C (6 months: 40.7+/-10.7 mg/dl vs. 53.4+/-16.5; p=0.02; 12 months: 47.2+/-7.9 mg/dl vs. 63.2+/-16.3mg/dl; p<0.01; tibolone vs. placebo group, respectively). There were no differences between the two groups in any of the remaining variables. CONCLUSION: In patients with inactive or stable SLE, the short-term use of tibolone did not significantly affect the frequency of flares. In addition, tibolone was well tolerated and effective to control hypoestrogenism related symptoms in SLE patients.

RESUMO

PURPOSE: to evaluate whether the presence of insulin resistance (IR) alters cardiovascular risk factors in women with polycystic ovary syndrome (POS). METHODS: transversal study where 60 POS women with ages from 18 to 35 years old, with no hormone intake, were evaluated. IR was assessed through the quantitative insulin sensitivity check index (QUICKI) and defined as QUICKI <0.33. The following variables have been compared between the groups with or without IR: anthropometric (weight, height, waist circumference, arterial blood pressure, cardiac frequency), laboratorial (homocysteine, interleucines-6, factor of tumoral-alpha necrosis, testosterone, fraction of free androgen, total cholesterol and fractions, triglycerides, C reactive protein, insulin, glucose), and ultrasonographical (distensibility and carotid intima-media thickness, dilation mediated by the brachial artery flux). RESULTS: Eighteen women (30%) presented IR and showed significant differences in the following anthropometric markers, as compared to the women without IR (POS with and without IR respectively): body mass index (35.56+/-5.69 kg/m(2) versus 23.90+/-4.88 kg/m(2), p<0.01), waist (108.17+/-11.53 versus 79.54+/-11.12 cm, p<0.01), systolic blood pressure (128.00+/-10.80 mmHg versus 114.07+/-8.97 mmHg, p<0.01), diastolic blood pressure (83.67+/-9.63 mmHg versus 77.07+/-7.59 mmHg, p=0.01). It has also been observed significant differences in the following laboratorial markers: triglycerides (120.00+/-56.53 mg/dL versus 77.79+/-53.46 mg/dL, p=0.01), HDL (43.06+/-6.30 mg/dL versus 40.45+/-10.82 mg/dL, p=0.01), reactive C protein (7.98+/-10.54 mg/L versus 2.61+/-3.21 mg/L, p<0.01), insulin (28.01+/-18.18 microU/mL versus 5.38+/-2.48 microU/mL, p<0.01), glucose (93.56+/-10.00 mg/dL versus 87.52+/-8.75 mg/dL, p=0.02). Additionally, two out of the three ultrasonographical markers of cardiovascular risk were also different between the groups: carotid distensibility (0.24+/-0.05 mmHg-1 versus 0.30+/-0.08 mmHg-1, p<0.01) and carotid intima-media thickness (0.52+/-0.08 mm versus 0.43+/-0.09, p<0.01). Besides, the metabolic syndrome ratio was higher in women with IR (nine cases=50% versus three cases=7.1%, p<0.01). CONCLUSIONS: POS and IR women present significant differences in several ultrasonographical, seric and anthropometric markers, which point out to higher cardiovascular risk, as compared to women without POS and IR. In face of that, the systematic IR evaluation in POS women may help to identify patients with cardiovascular risk.

RESUMO

OBJETIVOS: Caracterizar as pacientes com valores indeterminados de hiperprolactinemia (teste de PEG para identificação de macroprolactinemias com recuperação entre 30 e 65 por cento) (PRLi) ou macroprolactinemia (PRLm), quanto às características clínicas, como intensidade e variação dos sintomas e presença ou não de tumores no sistema nervoso central. MÉTODOS: Estudo transversal, retrospectivo, de levantamento de prontuários, no qual foram incluídas 24 pacientes com diagnóstico de hiperprolactinemia (PRL>25 ng/dL), em idade reprodutiva, em seguimento em ambulatório de ginecologia endócrina. Foram incluídas 11 pacientes com PRLm e 13 com PRLi. Dos dois grupos (PRLm e PRLi), foram considerados para a análise registros dos dados relativos à idade, à paridade, ao índice de massa corporal, à presença de galactorreia, à infertilidade e ao tumor do sistema nervoso central. Os dados antropométricos foram expressos em média e desvio padrão e, para a comparação entre os grupos quanto à presença de tumor no sistema nervoso central, galactorreia e infertilidade, utilizou-se o teste t de Student. RESULTADOS: A galactorreia foi mais prevalente nas pacientes com PRLi (p=0,01). Setenta por cento das mulheres com PRLi apresentaram microprolactinoma de hipófise, enquanto que este achado foi evidente em 17 por cento das mulheres com PRLm (p=0,04). Dentre as pacientes com PRLm e PRLi, nove não foram investigadas com imagem do sistema nervoso central por apresentarem níveis pouco elevados de prolactina (cinco portadoras de PRLm e quatro de PRLi). Não houve diferença significativa quanto à ocorrência de infertilidade ou de ciclos menstruais irregulares. CONCLUSÕES: Mulheres com hiperprolactinemia intermediária apresentam mais sintomas de galactorreia e maior incidência de tumores do sistema nervoso central do que aquelas com macroprolactinemia.


PURPOSE: To characterize patients with indeterminate values of hyperprolactinemia (PEG test for the identification of macroprolactinemias with recovery between 30 and 65 percent) (PRLi) or macroprolactinemia (PRLm), in relation to clinical characteristics, such as the presence or absence of symptoms, as well as their intensity and variation, and the presence or absence of central nervous system tumors. METHODS: This is a cross-sectional retrospective survey of records of 24 patients with hyperprolactinemia, in reproductive ages, with prolactin >25 ng/dL. Eleven women with PRLm and 13 with PRLi were included. Records from the two groups were extracted for analysis: age, parity, body mass index, presence of galactorrhea, infertility, and central nervous system tumor. Anthropometrics data were expressed as mean and standard deviation. To compare groups regarding the presence of central nervous system tumor, galactorrhea, as well as infertility we used the Student's t-test. RESULTS: Galactorrhea was more prevalent in patients with PRLi (p=0.01). Seventy percent of women with PRLi presented pituitary tumor (microprolactinoma), whereas this finding was evident in 17 percent of the PRLm Group (p=0.04). Among the patients with and PRLm PRLi, nine were not investigated with the image of the central nervous system because they have low levels of prolactin (five carriers and four PRLm PRLi). There were no significant differences regarding the occurrence of infertility or irregular menstrual cycles between groups. DISCUSSION: Women with intermediate hyperprolactinemia present more galactorrhea symptoms as well as central nervous system tumors than women with macroprolactinemia.
