Dexketoprofen más pamabrom versus acetaminofen en dismenorrea primaria: estudio controlado, randomizado, doble ciego, multicéntrico / Dexketoprofen plus pamabrom versus acetaminophen in primary dysmenorrhea: a controlled, randomized, double-blind, multicenter study

RESUMEN Introducción: se sabe que las concentraciones plasmáticas de hormona antidiurética o vasopresina son más altas en las mujeres con dismenorrea primaria (DiPr) y podría ser causa de retención de agua con signos y síntomas concomitantes que agravan su cuadro clínico. La monoterapia con AINEs en ocasiones alcanza solo un alivio parcial porque no incide sobre la vasopresina. Objetivo: evaluar la eficacia y tolerabilidad del dexketoprofeno + pamabrom en la DiPr tomando como referencia el acetaminofén. Materiales y métodos: estudio doble ciego, controlado, randomizado, en pacientes con DiPr asignados al azar. Fueron aleatorizadas 172 pacientes, 86 en cada grupo 1) Grupo casos (DP): dexketoprofeno + pamabrom o 2) Grupo control (AC): acetaminofén. Se evaluó la evolución de la intensidad del dolor, el alivio del dolor, la gravedad de otros síntomas presentes y la satisfacción global del médico y paciente. Se registró las reacciones adversas. Resultados: la disminución de la intensidad del dolor, de los síntomas acompañantes y el alivio del dolor evaluados por la EVA, la PID, la SPID, el PAR y el TOTPAR respectivamente es mayor y más rápida de modo significativo en todos los tiempos para la combinación DP. Las reacciones adversas fueron mínimas. La satisfacción global de pacientes y médicos respecto al tratamiento es significativa a favor de la combinación DP. Conclusiones: dexketoprofeno + pamabrom es significativamente más eficaz y rápido en el control del dolor y otros síntomas presentes en la dismenorrea primaria que acetaminofén demostrando la validez de añadir un diurético suave a un AINE para incrementar su eficacia. El tratamiento DP es bien tolerado (AU).

ABSTRACT Background: It is known that plasma concentrations of antidiuretic hormone or vasopressin are higher in women with primary dysmenorrhea (DiPr) and could cause water retention with concomitant signs and symptoms that aggravate the illness. Monotherapy with NSAIDs sometimes achieves only partial relief because it does not affect vasopressin. Objective: The aim was to evaluate the efficacy and tolerability of dexketoprofen + pamabrom in DiPr taking as reference acetaminophen. Materials and methods: Double-blind, controlled, randomized study in patients with DiPr random to 1) Case group (PD): dexketoprofen + pamabrom or 2) Control group (CA): acetaminophen. The evolution of pain intensity, pain relief, severity of other present symptoms and overall satisfaction of the doctor and patient were evaluated. Adverse reactions were recorded. Results: 172 patients were randomized, 86 in each group. The decrease in pain intensity, accompanying symptoms and pain relief evaluated by VAS, PID, SPID, PAR and TOTPAR respectively is significantly greater and faster at all times for the combination DP. Adverse reactions were minimal. The overall satisfaction of patients and doctors regarding treatment is significant in favor of the DP combination. Conclusions: Dexketoprofen + pamabrom is significantly more effective and faster in the control of pain and other symptoms present in primary dysmenorrhea than acetaminophen demonstrating the validity of adding a mild diuretic to an NSAID to increase its effectiveness. DP treatment is well tolerated (AU).

Dismenorreia membranosa: uma doença esquecida / Membranous dysmenorrhea: a forgotten disease

OBJETIVO: apresentar uma série de casos de dismenorreia membranosa. MÉTODOS: todas as pacientes foram selecionadas a partir da suspeição diagnóstica, após atendimento clínico em consultório privado por relato de dismenorreia dolorosa associada à eliminação espontânea de material elástico com formato semelhante a útero. Apenas fatos relevantes foram descritos do quadro álgico, história médica atual e pregressa e hábitos de vida. O material eliminado foi encaminhado para laboratório de patologia no qual ocorreu a análise macro e microscópica. Os casos em que não se pode provar a eliminação de material com característica membranácea não foram selecionados. Após a confirmação diagnóstica, realizou-se uma revisão da literatura até o ano de 2008 utilizando o método MeSH com o termo "membranous dysmenorrhea". RESULTADOS: três casos clínicos de dismenorreia foram transcritos. Todos os casos, além do quadro característico de dor e eliminação vaginal de material elástico, foram associados ao uso de métodos anticoncepcionais hormonais. CONCLUSÕES: embora haja apenas escassos relatos de caso de dismenorreia membranosa na literatura científica, sua etiologia deve ser suspeita em casos de dor associada a sangramento vaginal com eliminação de material elástico ou firme. O diagnóstico final é dependente do exame anatomopatológico que nunca deve ser dispensado. Observamos necessidade de mais discussões sobre esta patologia com o objetivo de manter o profissional atualizado para exercer diagnóstico e terapêutica adequados.

PURPOSE: to present a series of cases of membranous dysmenorrhea. METHODS: all the patients selected were under diagnostic suspicion, after being clinically attended in a private medical office due to the report of painful dysmenorrhea associated with spontaneous elimination of elastic material with uterine shape. Only relevant facts about the pain condition have been described, together with the present and previous medical history and life habits. The material eliminated was forwarded to the pathology laboratory, where the macro and microscopic analyses were done. Cases with no confirmation of membranous material elimination were not selected. After the diagnostic confirmation, literature up to 2008 was carried out using the MeSH method, with the words "membranous dysmenorrheal". RESULTS: three cases of dysmenorrhea were transcribed. Besides the characteristic picture of pain and vaginal elimination of elastic material, all the cases were associated with the use of hormonal contraceptive methods. CONCLUSIONS: despite the fact that there are only sporadic reports of cases of membranous dysmenorrhea in the scientific literature, this etiology must be considered in cases of pain associated with vaginal bleeding plus elimination of elastic or solid material. The final diagnosis depends on anatomopathological exam, which should not be dismissed. We highlight the need for more discussion about this pathology, to keep the professionals updated with the aim of exerting adequate diagnosis and therapeutics.

Dismenorrea / Dysmenorrhea

La dismenorrea es la menstruación dolorosa de variable intensidad que puede asociarse a malestar general, cefalea, náuseas y vómitos. Afecta en algún período de la vida al 50 por ciento de la población femenina(especialmente adolescentes y adultos jóvenes). Disminuye su frecuencia con el uso de anticonceptivos orales y luego de partos vaginales. La dismenorrea puede ser primaria en la que no existe patología ginecológica orgánica y secundaria sea a afecciones ginecológicas (malformaciones, adenomiosis, endometriosis, etc.) o no ginecológicas(pélvicas, musculoesquelético, etc). Clínicamente la dismenorrea se clasifica en grado de 1 a 4 según la intensidad y su respuesta a los antinflamatorios

Dysmenorrhea.

Dysmenorrhea affects over 50% of menstruating women and causes extensive personal and public health problems, a high degree of absenteeism and severe economic loss. In primary dysmenorrhea there is no macroscopically identifiable pelvic pathology, while in secondary dysmenorrhea gross pathology is present in the pelvic structures. With primary dysmenorrhea the pain is suprapubic and spasmodic, and associated symptoms may be present. Characteristically dysmenorrhea starts at or shortly after menarche. The pain lasts for 48-72 hours during the menstrual flow and is most severe during the first or second day of menstruation. It is now clear that in many women with primary dysmenorrhea the pathophysiology is due to increased and/or abnormal uterine activity because of the excessive production and release of uterine prostaglandins. Treatment with many of the prostaglandin synthetase inhibitors (nonsteroidal antiinflammatory drugs) will produce significant relief from dysmenorrhea and a concomitant decrease in menstrual fluid prostaglandins. For dysmenorrheic women who desire oral contraception, this agent will relieve the dysmenorrhea by suppressing endometrial growth, thus resulting in a decrease in the menstrual flow as well as in menstrual fluid prostaglandins. For those not requiring oral contraception the drug of choice for primary dysmenorrhea remains a prostaglandin inhibitor. Laparoscopy need be resorted to only if a pelvic abnormality is detected on examination or if treatment with prostaglandin inhibitors for up to six months is not significantly effective. In secondary dysmenorrhea, relief is obtained when the pelvic pathology--such as ovarian cysts, uterine fibroids, adhesions, cervical stenosis, congenital malformation of the uterus and endometriosis--is treated. In women using IUDs the dysmenorrhea is readily controlled with prostaglandin inhibitors since the underlying pathophysiology is excessive prostaglandin production and release.
