Mielopatía por déficit de cobre: serie de casos y revisión de la literatura / Myelopathy due to copper deficiency: A case series and review of the literature

El déficit de cobre puede presentarse como una mielopatía y manifestarse como una ataxia sensorial secundaria a una desmielinización de los cordones posteriores de la médula espinal. Puede acompañarse de citopenias, principalmente anemia y leucopenia. Se presenta una serie de casos de tres pacientes con mielopatía por déficit de cobre, diagnosticados y manejados desde el año 2020 al 2022 en un hospital universitario de alta complejidad en Colombia. Dos de los casos eran mujeres. El rango de edad fue entre 57 y 68 años. En los tres casos, los niveles séricos de cobre estaban disminuidos y en dos de ellos, se descartaron diferentes causas de mielopatía que afectan los cordones posteriores de la médula espinal como el déficit de vitamina B12, vitamina E y ácido fólico, tabes dorsal, mielopatía por virus de la inmunodeficiencia humana, esclerosis múltiple e infección por el virus linfotrópico humano de tipo I y II, entre otras. Sin embargo, un paciente tenía deficiencia de vitamina B12 asociada con de cobre en el momento del diagnóstico de la mielopatía. En los tres casos hubo ataxia sensitiva y en dos, la paraparesia fue el déficit motor inicial. Se deben incluir siempre la determinación de los niveles de cobre dentro del abordaje diagnóstico de todo paciente con enfermedad gastrointestinal crónica, con diarrea crónica, síndrome de mala absorción o reducción significativa de la ingestión en la dieta, y que desarrolle síntomas neurológicos sugestivos de compromiso de los cordones, ya que se ha reportado que el retraso en el diagnóstico de las mielopatías se asocia con pobres desenlaces neurológicos.

Copper deficiency can present as myelopathy by the manifestation of sensory ataxia, secondary to demyelination of the posterior cords of the spinal cord, accompanied by cytopenia, mainly anemia, and leukopenia. Case series study of three patients with myelopathy due to copper deficiency, diagnosed and managed from 2020 to 2022 in a highly complex university hospital in Colombia. Regarding gender, two cases were female patients. The age range was between 57 and 68 years. In all three cases serum copper levels were decreased, and in two of these, different causes of myelopathy affecting the posterior cords of the spinal cord were ruled out, such as vitamin B12, vitamin E and folic acid deficiency, tabes dorsalis, myelopathy due to human immunodeficiency virus, multiple sclerosis and infection by the human lymphotropic virus type I and II, among others. However, at the moment of the myelopathy diagnosis, one patient had vitamin B12 deficiency associated with copper insufficiency. All three cases presented sensory ataxia, and in two, paraparesis was the initial motor deficit. The diagnostic approach must include copper levels assessment in every case of patients with chronic gastrointestinal pathology, chronic diarrhea, malabsorption syndrome, or significant reduction in dietary intake; and the development of neurological symptoms that may suggest cord involvement. It has been reported that a delay in diagnosis can lead to poor neurological outcomes.

Síndrome de plaquetas grises y embarazo: reporte de un caso y revisión de la bibliografía / Grey platelet syndrome and pregnancy: case report and literature review

Resumen ANTECEDENTES: Las repercusiones del embarazo en el síndrome de plaquetas grises no están definidas, la bibliografía reporta pocos casos; por tanto, los desenlaces no son muy conocidos. OBJETIVO: Describir el caso de una paciente con síndrome de plaquetas grises y embarazo para proponer pautas de atención y recomendaciones para el seguimiento antenatal, peri y posparto en este grupo de pacientes. Además, revisar la bibliografía más reciente. CASO CLÍNICO: Paciente primigesta de 29 años, con diagnóstico de trombocitopenia a partir de los 6 años. Durante el embarazo se consideró de origen genético por lo que se solicitó el exoma clínico que reportó una variante en el gen NBEAL2 c 7244G>T p G1y2415Val homocigoto, con diagnóstico de síndrome de plaquetas grises. Permaneció en seguimiento en los servicios de Hematología y Obstetricia, sin complicaciones mayores; cerca del parto requirió transfusión de plaquetas. A las 39 semanas de embarazo ingresó para atención del parto, se dio prueba de trabajo de parto; sin embargo, por indicación obstétrica (detención de la dilatación) se decidió la finalización mediante cesárea. METODOLOGÍA: Se revisaron las bases de datos de PubMed, LILACS, Medline, Clinical trials de los últimos 20 años. Los MeSH de búsqueda fueron "grey platelet" "syndrome" "pregnancy". Se encontraron 11 artículos de los que se descartaron 2 por estar fuera del rango de tiempo, un artículo duplicado y otros excluían embarazadas. En total se revisaron 9 artículos. CONCLUSIÓN: Este caso muestra que las mujeres con síndrome de plaquetas grises, si son debidamente acompañadas por un equipo interdisciplinario con experiencia pueden tener un embarazo y parto seguros.

Abstract BACKGROUND: The repercussions of pregnancy in grey platelet syndrome are undefined, with few cases reported in the literature; therefore, outcomes are not well known. OBJECTIVE: To describe the case of a patient with grey platelet syndrome and pregnancy in order to propose care guidelines and recommendations for antenatal, peri- and postpartum follow-up in this group of patients. In addition, to review the most recent literature. CLINICAL CASE: A 29-year-old primigravida patient diagnosed with thrombocytopenia since the age of 6. During pregnancy it was considered to be of genetic origin, so the clinical exome was requested, which reported a variant in the NBEAL2 c 7244G>T p G1y2415Val homozygous gene, with a diagnosis of grey platelet syndrome. She remained under follow-up in the haematology and obstetrics departments, without major complications; close to delivery she required platelet transfusion. At 39 weeks of pregnancy, she was admitted for delivery care, proof of labour was given; however, due to obstetric indications (arrest of dilatation) it was decided to terminate the pregnancy by caesarean section. METHODOLOGY: The databases of PubMed, LILACS, Medline, Clinical trials of the last 20 years were reviewed. The MeSH search terms were "grey platelet" "syndrome" "pregnancy". Eleven articles were found of which two were discarded for being out of time range, one article duplicated and others excluded pregnant women. In total 9 articles were reviewed. CONCLUSION: This case shows that women with grey platelet syndrome, if properly supported by an experienced interdisciplinary team, can have a safe pregnancy and delivery.

Asociación entre la variación de glóbulos blancos y las manifestaciones clínicas, anticuerpos e infecciones en adultos con lupus eritematoso sistémico / White blood cells count variation in systemic lupus erythematosus: its association to disease manifestations, antibodies and risk of infections

Introducción: la asociación de leucopenia, linfopenia y neutropenia con la presencia de autoanticuerpos, manifestaciones clínicas e infecciones en pacientes con lupus eritematoso sistémico (LES) no está bien establecida. Los objetivos de este estudio fueron analizar los cambios en los recuentos de leucocitos y linfocitos en pacientes con LES y su asociación con manifestaciones clínicas, autoanticuerpos y riesgo de infecciones. Materiales y métodos: se recolectaron retrospectivamente los valores de leucocitos, linfocitos y neutrófilos. Se agruparon a los pacientes en cinco categorías: recuento de glóbulos blancos normales, leucopenia (persistente o intermitente) y linfopenia (persistente o intermitente). Se registraron las manifestaciones clínicas, los autoanticuerpos acumulados, el daño, la mortalidad, las infecciones y los tratamientos inmunosupresores recibidos de cada paciente. Resultados: se incluyeron 89 pacientes. La linfopenia (89%) fue la anormalidad más frecuente. La leucopenia intermitente y la persistente se detectaron en el 44% y en el 11% de los pacientes, respectivamente. La linfopenia intermitente y la persistente se hallaron en el 44% y en el 45% de los casos. En el análisis univariado, la presencia de rash discoide se asoció a leucopenia (20,4 vs. 5,1; p=0,059) y el tratamiento con mofetil micofenolato a un recuento normal de leucocitos (p=0,046). El compromiso neurológico se asoció a recuento normal de linfocitos (22,2% vs. 0% y 7,5%; p=0,027); los pacientes con anti-RNP (anti ribonucleoproteína nuclear) presentaron más frecuentemente linfopenia persistente (47% vs. 15,4% y 20%; p=0,007). Ninguno de los grupos se asoció a una mayor prevalencia de infecciones. En el análisis multivariado, el mofetil micofenolato se asoció negativamente a leucopenia (OR 0.33 IC 95% 0,1-0,9; p=0,042) y el compromiso neurológico se asoció negativamente a linfopenia (OR 0.08; p=0,022). Conclusiones: en el análisis univariado, el rash discoide se asoció a leucopenia y el anti-RNP a linfopenia. Al ajustar por otras variables significativas, el tratamiento con mofetil micofenolato se asoció a un recuento normal de leucocitos, mientras que las manifestaciones neurológicas se relacionaron a linfocitos normales. No se demostró asociación de las infecciones con ninguno de los grupos.

Introduction: leukopenia, lymphopenia and neutropenia association to clinical manifestations and infections in systemic lupus erythematosus (SLE) is not well defined. The objectives were to analize leucocytes and lymphocytes variations in SLE patients and their association to clinical manifestations, autoantibodies and infections risk. Materials and methods: total white blood cell (WBC) count, lymphocyte, and neutrophils counts were collected retrospectively. Data were grouped into normal WBC cell count, persistent or intermittent leucopenia and lymphopenia. Disease manifestations, accumulated autoantibodies, damage, mortality, infections and immunosuppressants ever received were registered. Results: study sample included 89 patients. Lymphopenia (89%) was the most common abnormality. Intermittent and persistent leukopenia were detected in 44% and 11% cases. Intermittent and persistent lymphopenia were found in 44% and 45% cases. In univariate analysis, discoid rash was associated to leukopenia (20.4 vs 5.1 p=0.059) and mycophenolate treatment to normal leukocyte count (p=0.046). Patients with neurological disorder tended to have normal lymphocyte counts rather than intermittent or persistent lymphopenia (22.2% vs 0% and 7.5% p=0.027); patients with anti-RNP tended to belong to the persistent lymphopenia group (47% vs 15.4% and 20% p=0.007). Infections were not associated to any of the categories. In multivariate analysis mycophenolate was negatively associated to leukopenia (OR 0.33 95% CI 0.1-0.9 p=0.042) while neurological disorder was negatively associated to lymphopenia (OR 0.08 p=0.022). Conclusions: in univariate analysis, discoid rash was associated to leukopenia and anti-RNP to lymphopenia. When adjusted to other significant variables, mycophenolate was related to normal leukocyte while neurological manifestations were to normal lymphocyte counts. Infections were not associated to any of the categories.

Alterações hematológicas na dengue grave ­ uma revisão sistemática / Hematological changes in serious dengue ­ a systematic review

A infecção causada pelo vírus da dengue gera quase 400 milhões de novos casos a cada ano especialmente nos países tropicais e subtropicais, sendo considerada um problema de saúde pública em todo o mundo. Trata-se de uma doença sistêmica e infectocontagiosa, que pode ser classificada como dengue com ou sem sinais de alarme, e dengue grave. As alterações hematológicas estão relacionadas com a gravidade da doença e direcionam condutas médicas. Neste estudo foram realizadas buscas nas plataformas CAPES, LILACS e PubMed no período de janeiro de 2014 a janeiro de 2021 com o objetivo de reunir e avaliar artigos publicados que traziam informações sobre as alterações hematológicas na infecção de dengue grave. Após revisão minuciosa, foram incluídos no estudo um total de 15 artigos e os principais dados observados foram: diminuição da contagem de plaquetas (66,7%), aumento do hematócrito (26,6%), aumento do tempo de tromboplastina parcial ativada (26,6%) e leucopenia (26,6%).

The infection caused by the dengue virus generates almost 400 million new cases each year, especially in tropical and subtropical countries, being considered a public health problem worldwide. It is a systemic and infectious disease, which can be classified as dengue with or without alarm signs, and severe dengue. Hematological changes are related to the severity of the disease and may guide medical procedures. In this study, researches were carried out on the CAPES, LILACS and PubMed platforms with the aim of gathering and evaluating published articles that brought information about hematological changes in severe dengue infection from January 2014 to January 2021. After thorough review, a total of 15 articles were included in the study and the main data observed were: decreased platelet count (66.7%), increased hematocrit (26.6%), increased activated partial thromboplastin time (26.6%) and leukopenia (26.6%).

Haematological manifestations in primary hyperparathyroidism

Background & objectives: Primary hyperparathyroidism (PHPT) is a common endocrine disorder caused by the elevated secretion of the parathormone (PTH). The aim of this study was to evaluate the haematological manifestations of PHPT in patients with normal renal functions who were treated surgically for parathyroid adenomas. Methods: In this retrospective cross-sectional study, 134 patients with normal renal functions who underwent parathyroidectomies for PHPT were included. The haematological manifestations were evaluated in the total study cohort and in the two groups of different calcium (Ca) levels (Group 1 ?11.2 mg/dl and Group 2 ?11.2 mg/dl). Results: The overall prevalence of anaemia, leucopenia and thrombocytopenia was 20.1, 6.7 and 6.0 per cent, respectively. Normocytic anaemia was present in 19 (14.2%) patients. There were no significant differences in the prevalence of anaemia, leucopenia and thrombocytopenia between the two groups. There were no correlations between the PTH levels and the leukocyte, haemoglobin or platelet values. Six to 12 months after the parathyroidectomy (PTX), 35.7 per cent of the patients with anaemia, 85.7 per cent of the patients with leucopenia and 100 per cent of the patients with thrombocytopenia had recovered. Interpretation & conclusions: In the present study, anaemia was seen with a variable frequency in PHPT, but there was no relationship between anaemia and high PTH or Ca levels. The development of anaemia can be seen regardless of the PTH levels in PHPT patients with normal renal functions. High-resolution rates after PTX indicate a possible association between PHPT and thrombocytopenia or leucopenia, although their prevalence is low in PHPT.

Comparison between hematological and biochemical changes caused by conventional and metronomic chemotherapies in the treatment of canine transmissible venereal tumor / Comparação entre as alterações hematológicas e bioquímicas ocasionadas pela quimioterapia convencional e quimioterapia metronômica no tratamento do tumor venéreo transmissível canino

This study aimed to report the hematological and biochemical changes caused by conventional and metronomic chemotherapies, using vincristine sulfate to treat canine Transmissible Venereal Tumor (TVT). Twelve dogs were selected, six of them for the group receiving conventional chemotherapy (G1), and six dogs for the group receiving metronomic chemotherapy (G2). The G1 group received vincristine sulfate once a week at the dose of 0.75mg/m² until the tumor had disappeared with treatment, and the G2 group was treated with vincristine sulfate three times a week at the dose of 0.25mg/m2 until the tumor had disappeared. Before and after chemotherapy treatment, hematological and biochemical blood tests were performed to evaluate the main alterations caused by both chemotherapeutic models. Dogs undergoing conventional chemotherapy had significant leukocyte changes (p<0.05), causing neutropenia and leukopenia. In dogs undergoing metronomic chemotherapy, leukocytes remained within the reference range. Half of the dogs in group G1 had normochromic, normocytic anemia. The only biochemical alteration observed was the increase of urea in group G2. Thus, metronomic chemotherapy for the treatment of TVT with vincristine sulfate proved to be an excellent method for treatment, with fewer adverse effects, especially in maintaining the leukogram of dogs within normal range and reducing the number of anemia in animals during treatment.(AU)

Esta pesquisa teve como objetivo relatar as alterações hematológicas e bioquímicas causadas pelo tratamento quimioterápico convencional e pela quimioterapia metronômica, utilizando-se sulfato de vincristina para o tratamento do tumor venéreo transmissível canino(TVTC). Foram selecionados 12 cães, sendo seis para o grupo que recebeu quimioterapia convencional (G1) e seis cães para o grupo que recebeu quimioterapia metronômica (G2). O grupo G1 recebeu sulfato de vincristina, uma vez por semana, na dose de 0,75mg/m2, até o desaparecimento do tumor e o grupo G2 foi tratado com sulfato de vincristina, três vezes por semana, na dose de 0,25mg/m2, até o desaparecimento do tumor. Antes e após o tratamento quimioterápico foram realizados exames hematológicos e bioquímicos sanguíneos para avaliação das principais alterações causadas pelos dois modelos quimioterápicos. Os cães submetidos à quimioterapia convencional tiveram alterações leucocitárias significativas (p<0,05), causando uma leucopenia por neutropenia enquanto nos cães, submetidos à quimioterapia metronômica, os leucócitos mantiveram-se dentro do intervalo de referência. A metade dos cães do grupo G1 tiveram uma anemia do tipo normocítica normocrômica. A única alteração bioquímica observada foi o aumento da ureia no grupo G2. Desta forma, a quimioterapia metronômica para o tratamento do TVT com sulfato de vincristina, demonstrou ser um excelente método para a cura do animal, com menores reduções de efeitos adversos, sobretudo, na manutenção do leucograma dos cães e na redução de animais com anemia.(AU)

Altas dosis de cobalamina y ácido fólico en el tratamiento de leucopenias post covid-19 / High doses of cobalamin and folic acid in post-covid-19 leukopenia treatment

Introducción: La leucopenia es una de las manifestaciones observadas en pacientes que padecieron COVID-19 y sus características son similares a las observadas en deficiencia de vitamina B12 y ácido fólico. Objetivo: Mostrar la utilidad de altas dosis de vitamina B12 y ácido fólico en el tratamiento de leucopenias post COVID-19. Métodos: Estudio descriptivo transversal de tipo retrospectivo. Se recolectó datos demográficos, clínicos y laboratoriales de pacientes (n=22) con leucopenia post COVID-19 que fueron tratados con dosis de vitamina B12 y ácido fólico. Se valoró seguimiento de datos clínicos y laboratoriales correspondientes tanto al diagnóstico como a las 4 y 8 semanas del tratamiento. Resultados: El cuadro de leucopenia se revirtió totalmente, los leucocitos incrementaron hasta alcanzar valores normales. Los niveles de hemoglobina incrementaron, aunque sin alcanzar valores normales. Si bien los linfocitos no presentaron disminución al diagnóstico, estos incrementaron manteniéndose dentro de parámetros normales. El VCM se mantuvo con leves modificaciones y las plaquetas no presentaron modificaciones. La sintomatología remitió a los 2 meses. Conclusiones: Los datos obtenidos pueden servir como parte de los fundamentos para el tratamiento del síndrome post COVID-19.

Introduction: Leukopenia is one of the persistent manifestations in patients who have suffered from COVID-19 and its characteristics are similar to those patients with vitamin B12 and folic acid deficiency. Objective: To show the usefulness high doses of vitamin B12 and folic acid in post COVID-19 leukopenia treatment. Material and methods: Retrospective descriptive cross-sectional study. Demographic, clinical and laboratory data were collected from patients (n = 22) with post COVID-19 leukopenia who were treated with doses of vitamin B12 and folic acid. Follow-up of clinical and laboratory data corresponding to diagnosis as well as 4 and 8 weeks after treatment was assessed. Results: Leukopenia was totally reversed, leukocytes increased and reached normal values. Hemoglobin levels increased, although without reaching normal values. Lymphocytes increased within normal parameters though they were not decreased at diagnosis. MCV levels remained with slight modifications, and platelets without modifications. Patients symptoms subsided after 2 months treatment. Conclusion: Data obtained can serve as part of treatment rationale in post-COVID-19 syndrome.

Prognostic values of physical and hematological parameters of dogs naturally infected with parvovirus PVC-2: retrospective study of 103 cases / [Valores prognósticos de parâmetros físicos e hematológicos de cães naturalmente infectados pelo parvovírus PVC-2: estudo retrospectivo de 103 casos]

Canine parvovirosis is a high mortality disease with acute clinical picture. However, there are few available resources to help stablish prognosis accurately. This study aimed to determine the prognostic threshold values for vital and hematological parameters of dogs naturally infected by the Carnivore protoparvovirus 1 (CPV). A retrospective study of 103 canine parvovirosis cases was carried out. Twenty seven percent of these (28/103) died, 96% (27/28) of which within the first four days of hospitalization. Deceased animals had significantly higher median values for heart (HR) and respiratory (f) rates, as well as significantly lower systolic blood pressure (SBP) than survivors. Severely leukopenic animals (<1,000 cells/µL), had a significantly higher mortality rate (68%, n=13) compared to that of other patients (P<0.0007). Animals with at least two of the following findings: severe hypotension (SBP< 90mmHg), tachycardia (HR > 150 bpm) and leukopenia, represented 34% (34/101) of the cases and had a survival rate of 29% (10/34), while animals with at most one of these parameters represented 66% (67/101) and had a survival rate of 94% (63/67). The presence of two or three abnormal parameters was significantly related to the higher death risk among dogs with parvovirosis (P<0.0001).(AU)

A parvovirose canina é uma doença de alta mortalidade e de quadro clínico agudo. No entanto, existem poucos recursos para se estabelecer prognóstico de maneira precisa. Este estudo objetivou analisar os valores prognósticos de parâmetros físicos e hematológicos de cães naturalmente infectados pelo Carnivore protoparvovirus 1 (CPV). Um estudo retrospectivo de 103 casos de parvovirose canina foi realizado. Desses, 27% dos animais (28/103) foram a óbito, sendo 96% (27/28) com ocorrência nos primeiros quatro dias de internamento. Os cães que foram a óbito apresentaram medianas das frequências cardíaca (FC) e respiratória (f) significativamente maiores e pressão arterial sistólica (PAS) consideravelmente menor que a dos sobreviventes. Entre os animais mais intensamente leucopênicos (<1.000 células/(L), a taxa de mortalidade (68%, n=13) foi expressivamente maior que a dos demais pacientes (P<0,0007). Os animais com hipotensão grave (PAS<90mmHg), taquicardia (FC>150bpm) e leucopenia intensa (leucometria<1.000 células/µL), ou duas dessas alterações clínicas, representaram 34% (34/101) dos casos e tiveram taxa de sobrevida de 29% (10/34), enquanto os animais com, no máximo, um desses parâmetros alterados representaram 66% (67/101) dos animais, com taxa de sobrevida de 94% (63/67). A presença de dois ou três parâmetros alterados esteve significativamente relacionada ao maior risco de óbito de cães com parvovirose (P<0,0001).(AU)

Trametinib and dabrafenib induced rhabdomyolysis, renal failure, and visual loss. Report of one case

ABSTRACT MEK- and BRAF-inhibitors trametinib and dabrafenib are successfully used for BRAF-mutated, metastasizing melanoma, but these compounds may induce side effects. We report a 50 years old female with BRAF-mutated metastasizing melanoma who received trametinib (2 mg/d) and dabrafenib (200 mg/d) after using interferon without benefit. Shortly after starting trametinib/dabrafenib, she experienced an inability to abduct the left eye. Eight days after starting this therapy the patient experienced loss of appetite, vomiting, diarrhea, vertigo, and fever of 40°C. Two days later she experienced visual loss, requiring permanent support for her daily activities. Two further days later myoglobinuria appeared in the absence of myalgias or muscle weakness but accompanied by marked tiredness and inactivity. She could not eat or drink during four days prior to admission. The patient suspected an adverse effect of trametinib/dabrafenib and discontinued it 2 days prior to admission. Thereafter, she experienced an almost complete remission of the deficits except for ocular muscle weakness and visual impairment.

Los inhibidores de MEX and BRAF como trametinib y dabrafenib se usan en el melanoma metastásico con mutación BRAF, pero pueden tener efectos secundarios. Informamos una paciente de 50 años con un melanoma metastásico con la mutación BRAF que recibió trametinib (2 mg/día) y dabrafenib (200 mg/día) después de usar interferón sin beneficio. Después de iniciar esta terapia la paciente notó una incapacidad de abducir el ojo izquierdo. Ocho días después de iniciar el tratamiento, tuvo falta de apetito, vómitos, diarrea, vértigo y fiebre de 40°C. Dos días después notó pérdida de su agudeza visual, requiriendo asistencia para efectuar sus actividades de vida diaria. Dos días después apareció coluria, en ausencia de mialgias o debilidad muscular, pero acompañadas de fatiga. Ella no pudo comer o tomar líquidos por cuatro días antes de ingresar al hospital. La paciente sospechó que estaba experimentando efectos secundarios de los medicamentos y los suspendió dos días antes del ingreso, experimentando una casi completa remisión de sus síntomas, con excepción de la debilidad de musculatura ocular y déficit visual.

Investigation of the incidence of vitamin B12 deficiency in leukopenia and neutropenia secondary to infection

Background: Infections and nutritional deficiencies are the most common causes of the leucopenia and neutropenia. In this study, we aimed to find the incidence of vitamin B12 deficiency in patients with leukopenia and neutropenia secondary to infection.Methods: Between September 2018 and December 2018, patients who were referred to Diyarbak?r Children Hospital's Pediatric Hematology and Oncology Clinic for leukopenia and/ or neutropenia were thought to develop secondary to infection retrospectively evaluated.Results: Of the 60 patients that evaluated, 23(38.3%) were female and 37(61.7%) were male. The mean age'SD was 4.75'4.5 years. Severe neutropenia was detected in 5(8.3%), moderate neutropenia in 31(51.7%) and mild neutropenia in 17(28.3%) patients. Neutrophil counts were within normal limits in 7(11.7%) patients. When vitamin B12 levels were examined, 17(28.3%) patients had B12 deficiency.Conclusions: Investigation and treatment of vitamin B12 deficiency in patients with leukopenia and neutropenia may shorten the duration of cytopenia and prevent the development of secondary complications.

Study on the Intervention Effects of Huangqi Injection on Leukopenia Model Mice Based on LC-MS Metabolomics / 中国药房

OBJECTIVE：To study the intervention effects of Huan gqi injecti on on leucopenia model mice. METHODS ： Kunming mice were randomly divided into normal group ，model group and drug group ，with 8 mice in each group. Model group and drug group were given intraperitoneal injection of cyclophosphamide to induce leukopenia model. Normal group was given intraperitoneal injection of equal volume of sterile water. After modeling successfully ，normal group and model group were given intraperitoneal injection of equal volume of sterile water ；drug group was given intraperitoneal injection of Huangqi injection 0.04 mL/10 g，once a day ，for consecutive 7 d. Based on the detection of blood routine indexes （leukocyte，lymphocyte，neutrophil， monocyte count ）of mice in each group ，the metabolites in serum were analyzed by LC-MS. Principal component analysis （PCA）， partial least squares discriminant analysis （PLS-DA），orthogonal partial least squares-discriminant analysis （OPLS-DA），HMDB， METLIN， KEGG and other databases as well as related literatures were used to identify the differential metabolites. The metabolic pathways of differential metabolites were analyzed with MetPA online tools ，and the correlation of blood routine indexes and differential metabolites were analyzed on the basis of Pearson correlation coefficient. RESULTS： Compared with normal group ， blood rountine indexes of model group were decreased significantly （P＜ 0.01）. Compared with model group ，above blood r ountine indexes of drug group were all increased siginificantly （P＜0.01）. LC-MS chromatogram of serum samples in normal group and model group were significantly different ，and LC-MS metabonomics data of serum samples in drug group were similar to those of normal group. Multivariate statistical analysis and correlated database analysis revealed that compared with normal group ，serum contents of 17 metabolites as L-isoleucine，eicosapentaenoic acid were increased significantly in model group ，while the contents of 4 metabolites as spermidine were decreased significantly （P＜0.05 or P＜0.01）. Compared with model group ，Huangqi injection could reverse the serum contents of 9 metabolites in mice ，such as citric acid ，L-proline，acetylcarnitine，L-isoleucine， L-phenylalanine，sphingosine-1-phosphate，lysophosphatidylinositol，eicosapentaenoic acid and linoleic acid （P＜0.05 or P＜ 0.01），which were associated with linoleic acid metabolism ，biosynthesis of phenylalanine ，tyrosine and tryptophan ，and phenylalanine metabolism （metabolism pathway influential values were all higher than 0.1）. Correlation analysis showed that there was a significant correlation between blood routine indexes and the contents of D-sphingosine，linoleic acid and citric acid in model group（the absolute values of r were generally greater than 0.5）. CONCLUSIONS ：Huangqi injection can increase the counts of leukocytes，lymphocytes，neutrophils and monocytes in leucopenia model mice. The increase of leukocytes may be related to linoleic acid metabolism ，biosynthesis of phenylalanine ，tyrosine and tryptophan ，and phenylalanine metabolism.

Caso Clínico: Citopénia Autoinmune como complicación inmunológica de Trasplante Alogénico de Donante no emparentado, en paciente pediátrico con Anemia Drepanocítica / Clinical Case: Autoimmune Cytopenia as an immunological complication of Allogeneic Unrelated Donor Transplantation, in a pediatric patient with Sickle Cell Anemia

Introducción: La enfermedad de células falciformes es una condición heredada en la quese produce una hemoglobina anómala que desfavorece a la oxigenación tisular, crisis vaso-oclusivas y reacciones hemolíticas. Los pacientes con esta enfermedad presentan una activación anómala de la vía del complemento llevándolos al aumento en frecuencia de infecciones y enfermedades autoinmunes. Presentamos un caso de asociación de una enfermedad autoinmune en un paciente con enfermedad de células falciforme. Caso clínico: Niño de 10 años con Anemia drepanocítica (2009) con esplenectomía y crisis veno-oclusivas recurrentes, fue sometido a trasplante Alogénicoen abril del 2019fuera de la institución con donante isogrupo O+ no emparentado (10/10). Tratado con: Fludarabina ­Busulfan, Timoglobulina+ y Metotexate. Desarrolló Bicitopenia autoinmune y síndrome febril al día +165 post TPH. Glóbulos blancos: 360 uL, neutrófilos: 14 %, hemoglobina: 7.90 g/dL, plaquetas: 25000 uL, ferritina: 4695 ng/ml, IgG total: 9.88 gr/l, LDH: 190 UI/l. Proteína C reactiva: 2.79 mg/dL, Procalcitonina 0.13 ng/mL. Evolución: posterior a descartar infección viral, se completó un tratamiento antibiótico de amplio espectro y se realizó la suspensión del tratamiento inmunosupresor por sospecha de toxicidad, sin respuesta. Se realizó un estudio medular por citometría de flujo determinando una disminución de la línea linfoide B, y se concluye Citopenia Autoinmune como complicación inmunológica del trasplante. Desenlace: recibióterapia transfusional (plaquetoféresis + glóbulos rojos concentrados). Se utilizó metilprednisolona IV por 3 días y prednisona 30 mg por 14 días con reducción posterior gradual para inicio de Rituximab y ciclosporina. Se completó el tratamiento con Imnunoglobulina 6g IV por 5 días. Al alta glóbulos blancos: 5080 uL, neutrófilos: 67%, hemoglobina: 9.20 g/dL, plaquetas: 20000 uL, después de 18 días de ingreso hospitalario. Conclusión: Los resultados con el tratamiento en este caso sugieren que puede serrazonable considerar las citopeniasautoinmunes como una manifestación hematológica diagnóstica de la EICH crónica. Alternativamente, es posible que el tratamiento de citopenia inmune con esteroides, Rituximab y otros inmunosupresores

Introduction: Sickle cell disease is an inherited condition in which an abnormal hemoglobin is produced that impairs tissue oxygenation, vaso-occlusive crises and hemolytic reactions. Patients with this disease present an abnormal activation of the complement pathway, leading to an increase in the frequency of infections and autoimmune diseases. We present a case of association of an autoimmune disease in a patient with sickle cell disease. Clinical case:10-year-old boy with sickle cell anemia (2009) with splenectomy and recurrent veno-occlusive crisis, underwent Allogeneic transplantation in April 2019 outside the institution with an unrelated isogroup O + donor (10/10). Treated with: Fludarabine -Busulfan, Thymoglobulin + and Metotexate. He developed autoimmune bicytopenia and febrile syndrome at +165 day post HSCT. White blood cells: 360 uL, neutrophils: 14%, hemoglobin: 7.90 g / dL, platelets: 25,000 uL, ferritin: 4695 ng / ml, total IgG: 9.88 gr / l, LDH: 190 IU/l. C-reactive protein: 2.79 mg/dL, procalcitonin 0.13 ng / mL. Evolution:after ruling out viral infection, the patient completed a broad-spectrum antibiotic treatment and underwent suspension of immunosuppressive treatment due to suspected toxicity, with no response. A medullary study by flow cytometry was performed, determining a decrease in the B lymphoid line, and autoimmune cytopenia was concluded as an immunologicalcomplication of the transplant. Outcome:The patient received transfusion therapy (plateletpheresis + concentrated red blood cells). He also received IV methylprednisolone for 3 days and 30 mg prednisone for 14 days with gradual subsequent reduction to start Rituximab and cyclosporine. The treatment with Immunoglobulin 6g IV for 5 days was completed. At discharge, white blood cells: 5080 uL, neutrophils: 67%, hemoglobin: 9.20 g / dL, platelets: 20,000 uL, after 18 days of hospital admission. Conclusion:The results with treatment in this case suggest that it may be reasonable to consider autoimmune cytopenias asa diagnostic hematological manifestation of chronic GVHD. Alternatively, it is possible to treat immune cytopenia with steroids, rituximab, and other immunosuppressants

Bone marrow evaluation of patients having pancytopenia at tertiary care center, M. Y. hospital, Indore, India: one-year study

Background: Pancytopenia is reduction of all three formed elements of blood below the normal reference range leading to anemia, leucopenia, thrombocytopenia. Bone marrow aspiration is extremely helpful in evaluating the cause of pancytopenia by cellularity and cytology in order to prevent grave complications and mortality as the underlying pathology determines the management and prognosis of the patients. Aim of research study was to evaluate the patients having pancytopenia at tertiary care center, M.Y.H. Hospital, Indore, India.Methods: The present study was carried out over a period of one year from 2017 to 2018, in the Department of Pathology, M. Y. Hospital, Indore. During this period, a total of 109 bone marrow smears were examined. Out of these, 42 cases had the clinical presentation of pancytopenia. A detailed study was done regarding clinical examination and hematological and radiological investigations.Results: In this study 42 cases of pancytopenia were examined over a period of one year. The commonest cause of pancytopenia was megaloblastic anemia (33.34%) followed by aplastic anemia (19.05%). Others includes myelodysplastic syndrome (MDS), acute leukemia, erythroid hyperplasia and plasmacytosis.Conclusions: Bone marrow aspiration can diagnose majority of the cases of pancytopenia. Megaloblastic anemia and aplastic anemia are the commonest causes of pancytopenia.

Introducción: La Neutropenia Febril es una complicación potencialmente fatal del tratamiento del cáncer, relacionada con mayor morbilidad, mortalidad, disminución de dosis o retardo en los ciclos de quimioterapia, y resultados finales pobres. Estudios anteriores han demostrado el beneficio de Factor Estimulante de Colonias de Granulocitos en la reducción de tiempo de hospitalización, antibióticos intravenosos, fiebre y recuperación del conteo absoluto de neutrófilos. Se decide realizar el presente reporte ya que no existen datos respecto al manejo y respuesta al tratamiento en nuestro medio. Métodos: El presente estudio descriptivo, retrospectivo, fue realizado en el Instituto del Cáncer SOLCA ­ Cuenca. Se revisaron las historias clínicas del período 2010 ­ 2011. Las variables analizadas fueron: número de días de hospitalización, fiebre, uso de antibióticos intravenosos, y días de recuperación de neutropenia a >500/mm3 y >1000/mm3. Resultados: La estancia hospitalaria tuvo una mediana de 6 días, los días de terapia antibiótica intravenosa fueron iguales a los días de hospitalización. 79 eventos se recuperaron a un conteo absoluto de neutrófilos >500/mm3, en una mediana de 4 días; 72 eventos se recuperaron a >1000 /mm3 en una mediana de 4 días. La mayoría de los eventos se volvieron afebriles en una mediana de 1 día. Conclusión: Los resultados de las variables estancia hospitalaria, uso de antibióticos intravenosos y la duración de la fiebre fueron similares a los ya descritos en estudios anteriores, la recuperación del conteo absoluto de neutrófilos, fue más tardía, mostrando diferencias importantes con la bibliografía.

Introduction: Febrile Neutropenia is a potentially fatal complication of cancer treatment, related to higher morbidity, mortality, dose reduction or retard in chemotherapy cycles, and poor final outcomes. Previous studies have demonstrated the benefit of G-CSF (Granulocyte ­ Colony Stimulating Factors) in reduction of hospital stay, the use of intravenous antibiotics, fever and absolute neutrophil count (ANC) recovery. There is no data about the management and treatment response in our population. Methods: This is a retrospective descriptive study, developed in SOLCA ­ Cuenca Cancer Institute. 83 febrile neutropenia events met the inclusion and exclusion criteria, medical records from years 2010 to 2011 were reviewed. The analyzed variables were: days of hospital stay, fever, intravenous antibiotics use, and neutropenia recovery to a level >500/mm3 and >1000/mm3. Results: The median of hospital stay was 6 days, the duration of IV antibiotic therapy was the same as the days of hospital stay. 79 events recovered to an ANC >500/mm3, with a median of 4 days; 72 events recovered to >1000 /mm3 with a median of 4 days. The majority of events became afebrile with a median of 1 day. Conclusion: The results in the variables hospital stay, use of intravenous antibiotics and fever duration, were similar to those described in previous studies. The ANC recovery was delayed, showing important differences with cited references.

Resumen Introducción: la infección viral más importante postrasplante renal es la infección por citomegalovirus (CMV), hay discrepancia entre centros y países en datos de incidencia de infección-enfermedad en esta población de pacientes. Diseño: se realiza un estudio observacional analítico, tomando una cohorte retrospectiva de pacientes mayores de 18 años, trasplantados renales de donante vivo o cadavérico entre el 2004 y 2015 con al menos seis meses de seguimiento. Material y métodos: se realiza muestreo no probabilístico por conveniencia, se toman los datos de las historias clínicas de los pacientes trasplantados renales, calculando la densidad de incidencia de infección-enfermedad por CMV y se describen las características clínicas y demográficas de los pacientes que presentaron estas patologías. Resultados: se analizaron 252 pacientes, encontrando 92.4% receptores con riesgo intermedio para CMV y 7.5% con riesgo alto, ninguno fue de riesgo bajo. Se identificaron 19 casos, 13 con infección (5.1%) y seis con enfermedad (2.3%). El compromiso gastrointestinal fue el más frecuente. El tiempo promedio desde el momento del trasplante hasta la aparición de la infección-enfermedad fue de 417 (±479) y 650 días (±481), respectivamente. La tasa de infección fue de 10.08 casos por 1000 pacientes/año y la tasa de enfermedad de 5.88 por 1000 pacientes/año. Conclusiones: la densidad de incidencia de infección-enfermedad por CMV en pacientes trasplantados renales fue de 10.08 casos y 5.88 casos por 1000 pacientes/año, respectivamente. Estas tasas son menores a las reportados en la literatura. Dada la baja frecuencia de eventos, no fue posible establecer factores de asociación.

Abstract Introduction: the most important viral infection after renal transplantation is cytomegalovirus (CMV) infection. There is a discrepancy between centers and countries in terms of incidence data of infection-disease in this population of patients. Design: an analytical observational study was conducted, taking a retrospective cohort of patients older than 18 years old, kidney transplant recipients of living or cadaveric donors between 2004 and 2015, with at least 6 months of follow-up. Material and methods: non-probability convenience sampling was done; data from the clinical records of the kidney transplant patients were taken, calculating the incidence density of CMV infection-disease and the clinical and demographic characteristics of the patients who presented these pathologies were described. Results: 252 patients were analyzed; 92.4% of recipients with intermediate risk for CMV and 7.5% with high risk were found. None of them had low risk. 19 cases were identified, 13 with infection (5.1%) and 6 with disease (2.3%). Gastrointestinal involvement was the most frequent. The average time from the time of transplant to the onset of the infection-disease was 417 (± 479) and 650 days (± 481), respectively. The infection rate was 10.08 cases per 1000 patients / year and the disease rate was 5.88 per 1000 patients/year. Conclusions: the incidence density of CMV infection-disease in renal transplant patients was 10.08 cases and 5.88 cases per 1000 patients / year, respectively. These rates are lower than those reported in the literature. Given the low frequency of events, it was not possible to establish association factors. (Acta Med Colomb 2018; 43: 20-23).
