ABSTRACT
To investigate two clusters of severe fever with thrombocytopenia syndrome virus (SFTSV) in Xinyang City, Henan Province, in 2022, and analyze their causes, transmission route, risk factors, and the characteristics of virus genetic variation. Case search and case investigation were carried out according to the case definition. Blood samples from cases, family members and neighbors and samples of biological vectors were collected for RT-PCR to detect SFTSV. The whole genome sequencing and bioinformatics analysis were performed on the collected positive samples. A total of two clustered outbreaks occurred, involving two initial cases and ten secondary cases, all of which were family recurrent cases. Among them, nine secondary cases had close contact with the blood of the initial case, and it was determined that close contact with blood was the main risk factor for the two clustered outbreaks. After genome sequencing analysis, we found that the SFTSV genotype in two cases was type A, which was closely related to previous endemic strains in Xinyang. The nucleotide sequence of the SFTSV in the case was highly homologous, with a total of nine amino acid mutation sites in the coding region. It was not ruled out that its mutation sites might have an impact on the outbreak of the epidemic.

Liver disease-associated thrombocytopenia syndrome refers to thrombocytopenia caused by liver disease or the treatment of liver disease, and its incidence rate is related to the duration and severity of liver disease. The direct effect of thrombocytopenia on clinical outcomes is an increased risk of bleeding in patients with liver disease, whereas the indirect effect involves delay or termination of treatment due to the potential risk of bleeding. Liver disease-associated thrombocytopenia pathophysiological mechanisms involve decreased platelet production, abnormal distribution, destruction, or increased consumption. Presently, treatment strategies targeting different mechanisms include platelet-stimulating drugs, surgery, immunosuppressive drugs, and platelet transfusion, but the clinical application needs to be standardized further. The National Clinical Research Center for Infectious Diseases organized experts to discuss and formulate consensus with reference to the latest evidence-based medical evidence in the field so as to improve the clinical management level of liver disease-associated thrombocytopenia syndrome in China in terms of diagnosis, typing, and reasonable selection of treatment schemes.

Resumen El síndrome de Evans es una enfermedad conformada por la presencia simultánea o secuencial de trombocitopenia inmunitaria y anemia hemolítica autoinmunitaria, que puede ser primaria o secundaria a otra patología. Es una afección poco frecuente, por lo que es necesario tener una alta sospecha, y descartar otras patologías que cursan con dichas alteraciones hematológicas, para hacer el diagnóstico. Su manejo representa un desafío terapéutico dado su curso crónico y recidivante. La presentación durante el embarazo se asocia a morbilidad materna y fetal. A continuación presentamos el caso de una gestante en quien se pesquisó trombocitopenia severa aislada al ingreso al control prenatal, y que en el curso del embarazo desarrolló AHAI conformando un síndrome de Evans, que se consideró secundario a LES incompleto al realizar el estudio reumatológico. Debido a la pobre respuesta al tratamiento médico con corticoides e inmunosupresores, la mayor parte del embarazo se mantuvo hospitalizada para observación, ajuste y cambio de terapia, siendo necesario recurrir a manejo quirúrgico con esplenectomía.
Abstract Evans syndrome is a rare entity formed by the simultaneous or sequential presence of immune thrombocytopenia and autoimmune hemolytic anemia, which can be primary or secondary to another pathology. The presentation of this disease during pregnancy is associated with maternal and fetal morbidity. The syndrome's diagnosis requires a high suspicion and the ruling out of other pathologies that can happen with the same hematological alterations. The management represents a therapeutic challenge because of its chronic and recurrent course. Below we present the case of a pregnant woman in whom isolated severe thrombocytopenia was detected at admission for prenatal control, and who developed AIHA during the pregnancy, forming Evans syndrome, which was considered secondary to incomplete SLE when performing the rheumatological study. Due to the poor response to medical treatment with corticosteroids and immunosuppressants, the patient was hospitalized for most of her pregnancy for observation, adjustment and change of therapy, and even it was necessary resort to surgical management with splenectomy.

Resumen Introducción: La trombocitopenia inmune primaria (PTI) es una enfermedad caracterizada por la destrucción acelerada de plaquetas o la producción inadecuada de estas. Se puede clasificar según su etiología en primaria y secundaria. Métodos: Se presenta el caso de un paciente sexo masculino de 30 años de edad, que acude al servicio de urgencia dental del Hospital Barros Luco, por lesiones hemorrágicas mucosa oral y pequeñas manchas rojas en manos, brazos y espalda, de veinticuatro horas de evolución, asintomáticas y sin causa atribuible. Al examen físico se corrobora la presencia de múltiples vesículas hemorrágicas en región bucal y petequias en las zonas descritas. Se realiza diagnóstico presuntivo de PTI que se confirma al obtener un recuento plaquetario (RP) de 2000 uL. Se deriva a medicina interna para evaluación y manejo. La literatura describe que para confirmar esta enfermedad se requiere una historia clínica exhaustiva, descartar una patología sistémica o infecciosa previa y pruebas de laboratorio que evidencien recuento normal de células sanguíneas con una trombocitopenia marcada. Conclusión: El odontólogo tiene un rol significativo en el manejo multidisciplinario en este tipo de cuadros donde el conocimiento de manifestaciones orales de enfermedades sistémicas es de vital importancia para el diagnóstico, derivación y posterior tratamiento de estas.
Abstract Introduction: Primary immune thrombocytopenia (ITP) is a disease characterized by accelerated destruction of platelets or inadequate production of platelets. It can be classified according to its etiology in primary and secondary. Methods: We present the case of a 30-year-old male patient, who comes to the dental emergency service of the Barros Luco Hospital, for oral mucosa hemorrhagic lesions and small red spots on the hands, arms and back, 24 hours of evolution, asymptomatic and without attributable cause. Physical examination corroborates the presence of multiple hemorrhagic vesicles in the oral region and petechiae in the areas described. A presumptive diagnosis of ITP is made and confirmed by obtaining a platelet count (RP) of 2000 uL. He is referred to internal medicine for evaluation and management. The literature describes that confirming this disease requires an exhaustive medical history, ruling out a previous infectious or systemic pathology, and laboratory tests that show normal blood cell counts with marked thrombocytopenia. Conclusions: The dentist has a significant role in multidisciplinary management in this type of condition, where knowledge of oral manifestations of systemic diseases is of vital importance for the diagnosis, referral and subsequent treatment of these. Oral manifestations in primary immune thrombocytopenia patients. Case report

RESUMO Objetivo: Investigar os fatores prognósticos em pacientes graves com meningite bacteriana adquirida na comunidade e lesão renal aguda. Métodos: Estudo retrospectivo com inclusão de pacientes em um hospital terciário dedicado a doenças infecciosas localizado em Fortaleza (CE), com diagnóstico de meningite bacteriana adquirida na comunidade complicada por lesão renal aguda. Investigaram-se os fatores associados a óbito, ventilação mecânica e uso de vasopressores. Resultados: Incluíram-se 41 pacientes, com média de idade de 41,6 ± 15,5 anos, 56% dos quais do sexo masculino. O tempo médio entre a admissão à unidade de terapia intensiva e o diagnóstico de lesão renal aguda foi de 5,8 ± 10,6 dias. A mortalidade global foi de 53,7%. Segundo os critérios KDIGO, 10 pacientes foram classificados como estágio 1 (24,4%), 18 como estágio 2 (43,9%) e 13 como estágio 3 (31,7%). A classificação em estágio KDIGO 3 aumentou de forma significante a mortalidade (OR = 6,67; IC95% = 1,23 - 36,23; p = 0,028). A presença de trombocitopenia não se associou com aumento da mortalidade, porém foi um fator de risco para a ocorrência da classificação KDIGO 3 (OR = 5,67; IC95% = 1,25 - 25,61; p = 0,024) e para necessidade de utilizar ventilação mecânica (OR = 6,25; IC95% = 1,33 - 29,37; p = 0,02). Os pacientes que necessitaram de ventilação mecânica 48 horas após o diagnóstico de lesão renal aguda tiveram níveis mais elevados de ureia (44,6 versus 74mg/dL; p = 0,039) e sódio (138,6 versus 144,1mEq/L; p = 0,036). Conclusão: A mortalidade de pacientes graves com meningite bacteriana adquirida na comunidade e lesão renal aguda é alta. A severidade da lesão renal aguda se associou com mortalidade ainda mais elevada. A presença de trombocitopenia se associou com lesão renal aguda mais grave. Níveis mais elevados de ureia podem prever mais precocemente a ocorrência de lesão renal aguda de maior gravidade.
ABSTRACT Objective: To investigate prognostic factors among critically ill patients with community-acquired bacterial meningitis and acute kidney injury. Methods: A retrospective study including patients admitted to a tertiary infectious disease hospital in Fortaleza, Brazil diagnosed with community-acquired bacterial meningitis complicated with acute kidney injury. Factors associated with death, mechanical ventilation and use of vasopressors were investigated. Results: Forty-one patients were included, with a mean age of 41.6 ± 15.5 years; 56% were males. Mean time between intensive care unit admission and acute kidney injury diagnosis was 5.8 ± 10.6 days. Overall mortality was 53.7%. According to KDIGO criteria, 10 patients were classified as stage 1 (24.4%), 18 as stage 2 (43.9%) and 13 as stage 3 (31.7%). KDIGO 3 significantly increased mortality (OR = 6.67; 95%CI = 1.23 - 36.23; p = 0.028). Thrombocytopenia was not associated with higher mortality, but it was a risk factor for KDIGO 3 (OR = 5.67; 95%CI = 1.25 - 25.61; p = 0.024) and for mechanical ventilation (OR = 6.25; 95%CI = 1.33 - 29.37; p = 0.02). Patients who needed mechanical ventilation by 48 hours from acute kidney injury diagnosis had higher urea (44.6 versus 74mg/dL, p = 0.039) and sodium (138.6 versus 144.1mEq/L; p = 0.036). Conclusion: Mortality among critically ill patients with community-acquired bacterial meningitis and acute kidney injury is high. Acute kidney injury severity was associated with even higher mortality. Thrombocytopenia was associated with severer acute kidney injury. Higher urea was an earlier predictor of severer acute kidney injury than was creatinine.

ABSTRACT MYH9-related disease is an autosomal dominant disorder caused by mutations of the MYH9 gene, which encodes the non-muscle myosin heavy chain IIA on chromosome 22q12. It is characterized by congenital macrothrombocytopenia, bleeding tendency, hearing loss, and cataracts. Nephropathy occurs in approximately 30% of MYH9-related disease in a male patient carrier of a de novo missense mutation in exon 1 of the MYH9 gene [c.287C > T; p.Ser(TCG)96(TTG)Leu]. He presented all phenotypic manifestations of the disease, but cataracts. Renal alterations were microhematuria, nephrotic-range proteinuria (up to 7.5 g/24h), and rapid loss of renal function. The decline per year of the glomerular filtration rate was 20 mL/min/1.73m2 for five years. Blockade of the renin-angiotensin system, the only recommended therapy for slowing the progression of this nephropathy, was prescribed. Although MYH9-related disease is a rare cause of glomerulopathy and end-stage renal disease, awareness of rare genetic kidney disorders is essential to ensure accurate diagnosis and proper management of orphan disease patients.
RESUMO A doença relacionada ao MYH9 é um distúrbio autossômico dominante causado por mutações no gene MYH9 que codifica a cadeia pesada da miosina não muscular IIA no cromossomo 22q12. Ela é caracterizada por macrotrombocitopenia congênita, tendência a sangramento, perda auditiva e catarata. A nefropatia ocorre em aproximadamente 30% dos pacientes. O presente artigo relata o caso de um paciente com doença relacionada ao MYH9 portador de mutação missense de novo no exon 1 do gene MYH9 [c.287C > T; p.Ser(TCG)96(TTG)Leu]. Com a exceção de catarata, o paciente apresentou todas as manifestações fenotípicas da doença. As alterações renais incluíram micro-hematúria, proteinúria nefrótica (até 7,5 g/24h) e perda rápida da função renal. O declínio anual da taxa de filtração glomerular foi de 20 mL/min/1,73 m2 durante cinco anos. Foi receitado bloqueio do sistema renina-angiotensina, a única terapia recomendada para retardar a progressão dessa nefropatia. Embora a doença relacionada ao MYH9 seja uma causa rara de glomerulopatia e doença renal terminal, a conscientização sobre distúrbios genéticos renais raros é essencial para garantir o diagnóstico preciso e o manejo adequado dos pacientes com tal doença órfã.

Introducción. Las inmunodeficiencias primarias son un grupo de enfermedades de origen genético que implican altera - ciones asociadas a la respuesta inmunológica. El infra diagnóstico de estas conlleva al retraso de tratamiento, evitables en gran parte; Entre estas existe el síndrome de Wiskott-Aldrich; es un trastorno raro, ligado al cromosoma X, recesivo, que se caracteriza por trom - bocitopenia, eczema e inmunodeficiencia donde su tratamiento curativo es el trasplante de medula ósea. CASO CLÍNICO : Paciente de 10 años, con antecedentes de múltiples hospitalizaciones por procesos infecciosos importantes: neumonías recurrentes, menin - gitis, diarreas, erupción cutánea generalizada y trombocitopenia de hasta 9,000 mm³. Después de múltiples estudios realizados, se confirma el diagnóstico de síndrome de Wiskott -Aldrich por inmunogenetica (mutación del gen WAS) y mediante colaboración médica internacional, se realiza trasplante de médula ósea con posterior resolución de su enfermedad. DISCUSION: Las inmunodeficiencias primarias son patologías más comunes de lo que se creía (prevalencia de hasta 1/1200), la evidencia de aparición y su importancia clínica deben ser tomadas en consideración. En este caso de Síndrome de Wiskot-Aldrich en donde el diagnóstico definitivo es in - munogenetico, (actualmente el país no cuenta), además de tratamiento inmuno-oncológico adecuado, el paciente pudo sobrevivir y mejorar su calidad de vida gracias a soporte investigativo y terapéutico multinacional.

The causes of cytopenia in patients with severe fever with thrombocytopenia syndrome (SFTS) are not fully understood until now. We reviewed the bone marrow (BM) findings of patients with SFTS to unravel the cause of the cytopenia. Three Korean SFTS were enrolled in this study. Thrombocytopenia, neutropenia, and anemia were detected in all three patients. Severe hypocellular marrow (overall cellularity <5%) and a decreased number of megakaryocytes were noted in one patient, and hypo-/normocellular marrow and an increased number of hemophagocytic histiocytes were observed in two patients. Megakaryocytes were relatively preserved in two patients. Although a limited number of cases are available, our observations suggest that both BM suppression and peripheral destruction or sequestration are causes of cytopenia of patients with SFTS. To the best of our knowledge, this is the first well documented pathologic evaluation of Korean SFTS.

La trombocitopenia se encuentra presente entre un 6 al 10% de los todos los embarazos. La trombocitopenia gestacional (TG) es definida como una trombocitopenia moderada que ocurre en el tercer trimestre del embarazo y presenta remisión espontanea después del parto no estando relacionada a la trombocitopenia neonatal. Asimismo, no requiere tratamiento y existen pocos datos para distinguirla de la Púrpura Trombocitopénica Inmune en mujeres embarazadas de las no embarazadas debido a que el manejo clínico es diferente En este trabajo se pretende establecer un método confiable para el recuento de plaquetas (RP) y repasar las diferentes causas de trombocitopenia en nuestra Institución.Se incluyeron 9.890 mujeres embarazadas que ingresaron al Servicio de Obstetricia del Hospital "José R. Vidal" de la Ciudad de Corrientes durante octubre 2009 a octubre 2011. La incidencia de trombocitopenia durante el embarazo encontrada fue del 6.7% de las cuales, 667 embarazadas con trombocitopenia, 459 (68.8%) presentaron trombocitopenia leve, 193 (28.9 %) trombocitopenia moderada y 15 (2.2 %) trombocitopenia severa. En la población normal, el RP promedio fue de 287.61 ± 9.78 109, en las pacientes con trombocitopenia fue de 90.59 ± 6.27 109con el método de Fonio mostrando una diferencia estadísticamente significativa entre ambos grupos (p < 0.05). Lasconclusiones de este estudio indican que la incidencia de trombocitopenia durante el embarazo es similar a la encontrada por otros autores y la TG es la causa más importante de trombocitopenia. Finalmente, existen diferencias significativas en el RP cuando se emplea el método indirecto de Fonio comparado con métodos automático
Thrombocytopenia during pregnancy is present between 6 to 10% of all pregnancies. Gestational thrombocytopenia (GT) is defined as a moderate thrombocytopenia, which occurs in the third trimester of pregnancy and the spontaneous remission is presents after birth and is not related to neonatal thrombocytopenia. The GT requires no treatment and there are few data to distinguish Púrpura thrombocytopenic autoimmune in the pregnant women and in the non-pregnant because the clinical management differs. The aim of this work was to establish a reliable method for counting platelets and analyzed different causes of thrombocytopenia in our institution. 9,890 pregnancy women were admitted to the Obstetrics Service of the Hospital "Jose R.Vidal" of Corrientes during October 2009-October 2011. The incidence of thrombocytopenia during pregnancy was found 6.7 % and of the 667 pregnant women with thrombocytopenia, 459 (68.8 %) had mild thrombocytopenia, 193 (28.9 %) moderate thrombocytopenia and 15 (2.2 %) severe thrombocytopenia. In the normal population average was 287.61 109± 9.78 in patients with thrombocytopenia was 90.59 ± 6.27 109using the method of Fonio which showing a statistically significant difference between groups (p < 0.05). The findings of this study were that the incidence of thrombocytopenia during pregnancy is similar to that found by other authors being the GT is the most important cause of thrombocytopenia. Finally, there are significant differences in the RP when the indirect method of Fonio compared to automatized methods

El síndrome de Evans Fisher, descrito por primera vez en 1951, es un desorden autoinmune caracterizado por la presencia simultánea o secuencial de anemia hemolítica, trombocitopenia inmune y, en ocasiones, neutropenia inmune; con una prueba de antiglobulina directa positiva. Puede ser de causa primaria o secundaria a otras condiciones, como el lupus eritematoso sistémico, los síndromes linfoproliferativos o inmunodeficiencias primarias. Es muy rara su asociación con la esclerodermia. Con el término esclerodermia, que en sentido literal significa piel dura, se designa un grupo de enfermedades y síndromes que tienen como característica común la induración y el engrosamiento cutáneos. Se caracteriza por la presencia de un depósito excesivo de los componentes del tejido conjuntivo, expresado en forma de fibrosis hística, y por alteraciones estructurales del lecho vascular. Con un cuadro clínico muy amplio, afecta fundamentalmente la piel y ciertos órganos internos, como tubo digestivo, pulmón, corazón y riñón. Se presenta una paciente femenina de 75 años de edad, piel negra, con antecedentes de hipertensión arterial, diabetes mellitus tipo 2, cardiopatía isquémica y esclerodermia, esta última diagnosticada seis meses antes de su ingreso. Acudió por decaimiento marcado, palidez cutáneo-mucosa intensa y petequias generalizadas. En los estudios realizados se detectó anemia y trombocitopenia severas, reticulocitosis, prueba de antiglobulina directa positiva e hipercelularidad medular con hiperplasia severa de los sistemas megacariopoyético y eritropoyético. Se diagnosticó un síndrome de Evans Fisher y se trató con esteroides e inmunomoduladores; se logró la mejoría clínica y la remisión hematológica
The Evans syndrome, first described in 1951, is an autoimmune disorder characterized by the simultaneous or sequential development of hemolytic anemia and immune thrombocytopenia or immune neutropenia. It may be of primary origin or secondary to other diseases or conditions such as systemic lupus erythematosus, lymphoproliferative disorders or primary immunodeficiencies. Its association with scleroderma is considered very rare. The word scleroderma, which literally means hard skin, designates a group of diseases and syndromes of common feature in induration and thickening the skin. It is characterized by the presence of excessive deposition of connective tissue components, expressed as histic fibrosis, and structural alterations of the vascular bed. With a broad clinical view, it primarily affects the skin and certain internal organs such as gastrointestinal tract, lung, heart and kidney. We present a 75 year-old female, black skin, with a history of hypertension, type 2 diabetes, ischemic heart disease and scleroderma, the latter diagnosed six months before admission. The patient referred marked weakness, pale skin and generalized petechiae. The complete blood count detected severe anemia, thrombocytopenia and reticulocytosis. Other studies showed positive direct Coombs test and severe hypercellularity. Evans Fisher syndrome was diagnosed and treated with steroids and immunomodulators; clinical improvement and hematologic remission was achieved

OBJETIVO: O presente trabalho tem como objetivo descrever o manejo do pré-natal e do parto em pacientes portadoras de hepatite autoimune associada à plaquetopenia moderada ou grave. MÉTODOS: Este trabalho foi realizado em hospital universitário, de nível terciário. Foram analisadas, retrospectivamente, 13 gestações em dez pacientes com diagnóstico de hepatite autoimune complicadas pela plaquetopenia. Os critérios de inclusão foram: diagnóstico clínico de hepatite autoimune, plaquetopenia moderada ou grave (contagem de plaquetas < 100 x 103/mm3), idade gestacional ao nascimento acima de 22 semanas e pacientes acompanhadas por equipe especializada da instituição. As variáveis estudadas incluíram idade materna, paridade, os regimes de tratamento, contagem de plaquetas, exames para investigação da função hepática, tipo de parto, peso ao nascer e idade gestacional no momento do parto. RESULTADOS: A média da idade materna foi de 24,5 anos (DP = 5,3) e seis (50%) ocorreram em nulíparas. Durante a gravidez, a monoterapia com prednisona foi adotada em 11 (92%) casos. De acordo com o perfil de autoanticorpos, sete (58%) gestações possuíam diagnóstico de hepatite autoimune tipo I, duas (17%) do tipo II e três (25%) eram portadoras de hepatite crônica criptogênica (títulos de autoanticorpos indetectáveis). A hipertensão portal foi caracterizada em 11 (92%) gestações. A idade gestacional média no parto foi de 36,9 semanas (DP = 1,5 semana), com média de peso ao nascer de 2446g (DP = 655g), sendo oito (67%) pequenos para a idade gestacional. No momento do parto, a plaquetopenia grave foi caracterizada em quatro (33%) casos e a cesárea foi realizada em sete (58%). As complicações no parto ocorreram em três casos (25%), uma paciente apresentou atonia uterina e duas, hematoma perineal. Não houve morte materna ou perinatal. CONCLUSÃO: As complicações em pacientes plaquetopênicas com hepatite autoimune são elevadas, no entanto, com os cuidados e atenção necessários, podem ser contornáveis. A associação de duas patologias graves parece aumentar o risco de prematuridade e restrição do crescimento fetal, demandando atenção pré-natal especializada, bem como vigilância do bem-estar do concepto.
OBJECTIVE: To describe the management of prenatal care and delivery in patients bearing autoimmune hepatitis associated with moderate or severe thrombocytopenia. METHODS: This study was performed in a tertiary level university hospital. Thirteen pregnancies in ten patients diagnosed with autoimmune hepatitis, complicated by thrombocytopenia, were retrospectively analyzed. The inclusion criteria were as follows: clinical diagnosis of autoimmune hepatitis, moderate or severe thrombocytopenia (platelet count < 100 x 103/mm3), gestational age at birth over 22 weeks, and patient followed-up by a specialized team at the institution. The variables studied were: maternal age, parity, treatment regimen, platelet count, examinations for investigation of hepatic function, type of delivery, weight at birth, and gestational age at the time of delivery. RESULTS: The average maternal age was 24.5 years (SD = 5.3) and six (50%) occurred in nulliparous women. During pregnancy, monotherapy with prednisone was adopted in 11 cases (92%). According to the autoantibody profiles, seven pregnancies (58%) had the autoimmune hepatitis type I diagnosis, two pregnancies had type II (17%), and three pregnancies (25%) had cryptogenic chronic hepatitis (undetectable titers of autoantibodies). Portal hypertension was featured in 11 pregnancies (92%). The average gestational age at delivery was 36.9 weeks (SD = 1.5 weeks), with an average weight at birth of 2,446 g (SD = 655 g). Eight infants (67%) were small for gestational age. At the time of delivery, severe thrombocytopenia was featured in four cases (33%) and cesarean surgery was performed in seven cases (58%). Complications at delivery occurred in three cases (25%), one patient presented uterine atony, and two patients presented perineal bruising. There was no perinatal or maternal death. CONCLUSION: The complications of thrombocytopenic patients with autoimmune hepatitis are elevated; nevertheless, with appropriate attention and care, they can be resolved. The association between two severe pathologies appears to increase the risk of prematurity and fetal growth restriction, demanding specialized prenatal care, as well as surveillance of newborn well-being.

Myelodysplastic Syndrome [MDS] is a disorder of haemopoietic stem cell. Since, it has not been commonly observed in Pakistan, this case study is to understand the scientific and therapeutical comprehension of MDS. An 81 year old male hypertensive patient was presented in a private hospital of Islamabad, Pakistan, with anemia. On medical investigation the physician prescribed him, multi-vitamins OD for a month; injection G-CSF 300 mcg once a week; Molgramostim 300 microg on every alternate day for 3 weeks: Thalidomide 100 mg OD with Alprazolam 0.5 mg at night for 4 weeks and 5'-azacytidine for a month. Clinical and pharmaceutical inaccuracies were observed. Moreover; the high cost and long term therapy are major obstacles to cure this disease. Therefore, affordable method and short-term effective therapy and reduced cost of drugs will help to cure the disease in more efficient way and in less time with more promising results
