Efectos colaterales de antibacilares en pacientes con enfermedad de Hansen / No disponible

Introducción: La Organización Mundial de la Salud (OMS) recomendó el uso de la poliquimioterapia (PQT) desde 1981, y desde 1998 esta pauta de tratamiento fue introducida en Paraguay. Desde ese entonces y hasta la actualidad el esquema Multibacilar (MB) comprende tres drogas: rifampicina, clofazimina y dapsona, y, el esquema Paucibacilar (PB), dos drogas: rifampicina y dapsona. Todas ellas relacionadas en mayor o menor medida a efectos colaterales. A pesar de ello, hay pocos estudios a nivel mundial, y ningún estudio en el Paraguay. Métodos: Estudio retrospectivo, observacional, de corte transversal con componente analítico, llevado a cabo en la Cátedra de Dermatología del Hospital de Clínicas - Universidad Nacional de Asunción, en San Lorenzo, Paraguay. En el periodo de enero de 2013 a octubre de 2017. Resultados: Fueron incluidos en el estudio 58 pacientes con enfermedad de Hansen, de los cuales 45 (78%) presentaron al menos un efecto colateral a la PQT, 3 pacientes presentaron más de un efecto colateral. De los 45, 25 (56%) fueron del sexo masculino y 20 (44%) del sexo femenino. En cuanto a la distribución por rango de edad: Dos (4%) en menores de 18 años, 8 (18%) de 19 a 30 años, 27 (18%) de 31 a 59 años y 8 (18%) 60 y más años. Seis (3%) pacientes de procedencia rural y 39 (87%) de procedencia urbana. Cuarenta y siete (98%) casos de efectos colaterales hematológicos (Anemia: 45; leucopenia: 1 y trombocitopenia: 1) y 1 (2%) caso de efecto colateral gastrointestinal (hepatitis). La conducta en casos de anemia: suplementación con hierro y ácido fólico: 40, suspensión de dapsona: 10 y ninguna conducta: 6 suspensión de la dapsona en 1 caso de leucopenia, suspensión de la dapsona en 1 caso de trombocitopenia y suspensión de la rifampicina en 1 caso de hepatitis. En 26 (58%) pacientes los efectos colaterales se presentaron al mes del inicio de la PQT, en 15 (33%) pacientes entre 2 y 5 meses del inicio y en 4 (9%) pacientes a los 6 y más meses del inicio. En 14 (31%) de los pacientes con efectos colaterales existía comorbilidad y en 31 (69%) casos, eran pacientes sanos. De los 45 pacientes, 41 (91%) estaban en tratamiento MB, 4 (9%) en tratamiento PB. Conclusión: La mayoría de los pacientes incluidos en el estudio presentaron efectos colaterales. Los hombres fueron los más afectados, el rango etario en el cual se presentaron con mayor frecuencia fue entre los 31 y 59 años. La mayoría procedían del medio urbano. Los efectos colaterales más frecuentes fueron los hematológicos y, de entre ellos, la anemia. Ante tal situación la medida más frecuentemente adoptada fue la suplementación con hierro y ácido fólico. En la mayoría de los casos los efectos colaterales aparecieron en el primer mes de recibir la medicación. Aquellos pacientes que recibieron PQT MB presentaron la mayor frecuencia de efectos colaterales

Introduction: The World Health Organization (WHO) recommends the implementation of multidrug (MDT) since 1981, and this régimen was introduced in Paraguay in 1998. The MDT administrate three drugs: rifampicin, clofazimine and dapsone to multibacillary patients (MB) and only two: rifampicina and dapsone to paucibacillary patients (PB). All the drugs have some adverse effects. But very few statistics have been carried out in the world on this matter and none at all in Paraguay. Methods: The work is a retrospective, observational, cross-sectional and analytical study carried out at Catedra de Dermatología del Hospital de Clínicas-Universidad Nacional de Asunción, San Lorenzo, Paraguay between January 2013 and October 2017. Results: Fifty eight leprosy patients were registered in the study and 45 (78%) presented at least one adverse effect to the MDT and 3 patients presented more tan one. 25/45 were men and 20 (44%) women. The age distributions were: Two (4%) less than 18 years old, 8 (18%) between 19-30 years old, 27(18%) 31-59 years old and 8 (18%) 60 and older. Six (3%) lived in rural setting and 39 (87%) urban. Forty seven (98%) presented adverse hematological effects (anemia: 45, leucopenia: 1 and thrombocytopenia:1) and 1 (2%) presented a gastrointestinal effect. Forty patients with anemia received iron and folic acid supplements and 6 cases with no modifications. There was 1 case leucopenia, 1 thrombocytopenia, and 1 hepatitis due to rifampicine. In 26 patients (58%) adverse effects were detected during first month of MDT, in 15 (33%) between 2-5 of treatment and in 4 (9%) patients after 6 or more months of treatment. Fourteen (31%) patients had comorbility and 31 (69%) were healthy patients. Forty one (91%) patients were receiving MB MDT and 4 (9%) PB MDT. Conclusions: The mayority of the patients in the study presented adverse effects. Men were the most affected and the mayority were in the 31-59 years age group and from urban settings. Most of the effects were hematological and among them, anemia the most frequent. These cases were supplemented with iron and folic acid. Most adverse effects appeared during the first month of treatment and MB MDT group was the most affected

Transient spontaneous engraftment of CD34 hematopoietic cord blood stem cells as seen in peripheral blood: treatment of leprosy patients with anemia by placental umbilical cord whole blood transfusion.

Cord blood, because of its rich mix of fetal and adult hemoglobin, high platelet and white blood cell (WBC) counts, and a plasma filled with cytokine and growth factors, as well as its hypoantigenic nature and altered metabolic profile, has all the potential of a real and safe alternative to adult blood transfusion. Our experience of 74 units (50 ml-146 ml mean, 86 ml +/- 7.6 ml SD, median 80 ml, mean packed cell volume 48 +/- 4.1 SD, mean percent hemoglobin concentration 16.2 g/dl +/- 1.8 g/dl of placental umbilical cord whole blood collection (from 1 April 1999) after lower uterine cesarean section (LUCS) from consenting mothers and transfusion of the same to 16 informed, consenting patients with percent plasma hemoglobin 8 g/dl or less, is presented here. After collection the blood was immediately preserved in the refrigerator and transfused within 72 hours of collection. Fifteen males and one female, aged 12-72 yrs (mean 48.4 yrs) participated: five cases were pausibacillary type (PB) and 11 cases were multibacillary type (MB). The clinical spectrum of the cases varied widely from the tuberculoid to the lepromatous type and one patient presented with gangrene of the leg preceding an auto amputation which was infested with maggots. Each case was approved by the institutional ethical committee and received two to eight units of freshly collected placental umbilical cord blood in one transfusion without encountering any clinical, immunological or non-immunological reaction. Seven days after completion of the placental umbilical cord blood transfusion, the peripheral blood hematopoietic stem cell (CD34) estimation revealed a rise from the pretransfusion base level (.09%), varying from 3.6% to 16.2%, in 75% of the cases, without provoking any clinical graft vs host reaction in any of the leprosy victims. This value returned to normal within three months in most cases.

Negligible clinical effects of thalidomide in patients with myelofibrosis with myeloid metaplasia.

We conducted a nonrandomized prospective phase II study of thalidomide in anemic patients with myelofibrosis with myeloid metaplasia (MMM), with or without preceding polycythemia vera or essential thrombocythemia, with a primary aim to improve anemia. Thalidomide was given in escalating doses with a target dose of 800 mg daily, but the median dose of thalidomide that was actually tolerated was 400 mg daily. Fifteen patients were entered into the study and 14 were evaluable for response. Five of 14 (36%) patients discontinued thalidomide before 3 mo because of side effects, and none of these five patients had a response at the time when thalidomide was stopped. When evaluated after 3 mo of therapy, none of the remaining nine patients exhibited a discernible clinical response. Three patients showed progressive disease defined as > 50% increase in the need for red cell transfusions. Treatment was poorly tolerated, with all patients reporting side effects of thalidomide, the most prominent being fatigue documented in 80% of patients. Two patients died while on study, one from acute myelogenous leukemia and one from pneumonia. We conclude that thalidomide given in doses employed in the treatment of multiple myeloma gives no clinically relevant hematological effects in advanced MMM and is hampered by a very high incidence of side effects.

Anemia leprosa / Leprosy anemia

Se presentan 3 casos de lepra que acusaban una anemia pronunciada. Durante 2 meses se le sometio a tratamiento con Diasone y se noto una franca mejoria de la anemia. Esto indica que a pesar de que las ulfonas son anemizantes se puede y se debe usarlas despues de haber estudiado e investigado la causa de la anemia.

Lepra e opilação

Opilação e lepra são duas calamidades nacionaes que estão desafiando a capacidade dos medicos e a visão dos dirigentes brasileiros.A primeira, pela extensão, trazendo em estado de anemia a quase totalidade da população rural, e no de permanente intoxicação, a urbana, constituindo o principal factor da decantada indolencia, da displicencia e da mentalidade apathica e passiva do povo brasileiro; a segunda, pela sua gravidade, durabilidade, repugnancia e incurabilidade; ainda mais, pela apavorante diffusão, desde trinta anos, em coincidencia com o incremento da immigração, o desenvolvimento dos meios de transportes e comunicações, a criação de indústrias extemporaneas e o estonteante urbanismo, em detrimento dos trabalhos agricolas.
