Abstract
Several prognostic models have been introduced to predict outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Endothelial activation and stress index (EASIX) is a surrogate of endothelial dysfunction which has been shown to predict outcomes of patients with various hematologic malignancies. However, the prognostic implication of EASIX for DLBCL is limited and warrants exploration. We conducted a retrospective study enrolling adult DLBCL patients including a discovery cohort from the single-centered university hospital database and a validation cohort from the independent nationwide multi-center registry. EASIX scores were calculated using creatinine, lactate dehydrogenase, and platelet levels. The receiver operating characteristic curve analysis was used to determine optimal cutoff. Statistical analysis explored the impact of EASIX on survival outcomes. A total of 323 patients were included in the discovery cohort. The optimal EASIX cutoff was 1.07 stratifying patients into low (53.9%) and high EASIX (46.1%) groups. Patients with high EASIX had worse 2-year progression-free survival (PFS) (53.4% vs. 81.5%, p<0.001) and overall survival (OS) (64.4% vs. 88.7%, p<0.001) than patients with low EASIX. Multivariate analysis revealed that older age, bulky disease, impaired performance status, and high EASIX were associated with an unfavorable OS. In the validation cohort of 499 patients, the optimal EASIX cutoff was 1.04. Similar to the discovery cohort, high EASIX score was associated with high-risk diseases, worse PFS, and inferior OS. In conclusion, EASIX score was significantly associated with survival outcomes and may be used as a simple prognostic tool to better risk-classify DLBCL.

Abstract
INTRODUCTION Ineffective erythropoiesis (IE) is a significant risk factor for osteoporosis in individuals with thalassemia. Growth differentiation factor-15 (GDF15), a biomarker of IE, was found to be elevated in thalassemia patients. This study aimed to examine the association between GDF15 levels and osteoporosis in patients with thalassemia. METHODS A cross-sectional study was conducted in 130 adult patients with thalassemia in Thailand. Bone mineral density (BMD) at the lumbar spine was evaluated by dual-energy X-ray absorptiometry (DXA), and with a Z-score of less than -2.0 SD was defined as osteoporosis. GDF-15 was measured using the enzyme-linked immunosorbent assay (ELISA). Logistic regression analysis was used to examine the associated factors with the development of osteoporosis. Receiver operator characteristic (ROC) curve analysis was used to estimate the threshold of GDF15 in predicting osteoporosis. RESULTS Osteoporosis was detected in 55.4% (72/130) of the patients. Advanced age and high GDF15 levels were positively associated with osteoporosis, while an increased hemoglobin level was negatively associated with osteoporosis in patients with thalassemia. In this study, the GDF15 level's ROC demonstrated a good performance in predicting osteoporosis (AUC=0.77). CONCLUSIONS The prevalence of osteoporosis is high among adult thalassemia patients. Age and high GDF15 levels were significantly associated with osteoporosis in this study. A higher hemoglobin level is associated with a lower risk of osteoporosis. This study suggest that GDF15 could be used as a predictive biomarker for osteoporosis in patients with thalassemia. Adequate red blood cell transfusions and suppression of GDF15 function may be beneficial in preventing osteoporosis.

Abstract
INTRODUCTION Patients with thalassemia increase the risk of developing cognitive impairment. Chronic anemia, oxidative stress from excess iron, and hypercoagulable state were related to this condition. The study regarding its prevalence and the associated factor in Southeast Asia is limited. Therefore, the study aimed to investigate the prevalence of cognitive impairment and associated factors. METHODS This was a cross-sectional study of thalassemic patients aged 18 years or more at the Hematology Clinic of Srinagarind Hospital, Khon Kaen University, Thailand, from January to May 2021. The Thai version of the Mini-Cog test was used to determine the presence of cognitive impairment. The clinical and laboratory parameters indicated as potential risk factors for dementia were evaluated in all patients. A stepwise logistic regression analysis was used to determine the associated risk factors for cognitive impairment. RESULTS Among 150 patients, cognitive impairment was found in 40 patients (26.7%). Age per 10-year increase (adjusted odds ratio [AOR] of 1.6), no iron chelation therapy (AOR of 9.8), current smoking (AOR of 5.0), hemoglobin (Hb) (AOR of 0.63), and ferritin (AOR of 1.0001) were independent factors associated with cognitive impairment. CONCLUSIONS The prevalence of cognitive impairment was high among thalassemic patients. Increasing age, low Hb, iron overload, and current smoking were significant associated factors with cognitive impairment. Screening for dementia in these patients is recommended, particularly in patients with high-risk factors.

Abstract
Febrile neutropenia (FN) is considered an oncologic emergency in acute leukemia. There were 250 FN events in 124 hospitalized patients with hematologic malignancy. These data imply that two FN events may occur per patient, yet data on the prevalence, risk factors, and outcomes of recurrent FN in adult patients with leukemia are limited. A retrospective cohort study was conducted that enrolled adult patients diagnosed with acute leukemia who developed FN. The eligible patients were categorized as with or without recurrent FN. A stepwise, multivariate logistic regression analysis was performed to identify predictors of recurrent FN. A total of 203 patients met the study criteria; of these, 46 (22.66%) had recurrent FN, and this group had a median of three recurrent FN emergencies. After adjusted, three independent factors remained in the final model including ALL, FN at admission, and treatment with idarubicin (3 days) and cytarabine (7 days). The three factors were positively associated with recurrent FN with adjusted odds ratios of 6.253, 4.068, and 10.757, respectively. No significant differences were found between the two groups in terms of other sources of infection, other pathogens, ICU stay, hospital stay, and mortality. ALL and FN at admission and treatment with idarubicin (3 days) and cytarabine (7 days) were associated with recurrent FN in acute leukemia patients with FN. Clinical outcomes for patients with or without recurrent FN were mostly comparable; however, due to its small sample size, further studies are required to confirm the results of this study.

Abstract
INTRODUCTION Liver iron overload is common in patients with thalassemia. In patients with beta-thalassemia, the correlation between serum ferritin and liver iron concentration is well established. The correlation between serum ferritin levels and liver iron concentrations in patients with alpha-thalassemia remains limited. METHODS This is a cross-sectional study in patients with alpha-thalassemia aged ≥ 18 years old at Srinagarind Hospital, Khon Kaen University, Thailand. Liver iron concentration (LIC) was evaluated by the MRI-T2* technique. Linear logistic regression analysis was used to determine the correlation between serum ferritin levels and liver iron concentrations. RESULTS One hundred and thirty-one of the MRI-T2* measurements from 65 patients with alpha-thalassemia were evaluated. Patients with non-deletional alpha-thalassemia had higher LIC compared to patients with deletional alpha-thalassemia. The serum ferritin levels were relatively low at the same levels of LIC in patients with non-deletional alpha-thalassemia compared to deletional alpha-thalassemia. CONCLUSIONS The correlation of serum ferritin levels and LIC was modest and different among alpha-thalassemia genotypes. A different serum ferritin threshold is needed to guide iron chelation therapy in patients with alpha-thalassemia. Evaluation of liver iron concentration is necessary for patients with alpha-thalassemia, especially in patients with non-deletional alpha-thalassemia.

Abstract
BACKGROUND Acute leukemia is mainly treated with chemotherapy leading to febrile neutropenia (FN). There is limited data on clinical factors predictive of mortality in adults with acute leukemia and FN. METHODS This was a retrospective cohort study and enrolled adult patients, diagnosed as acute leukemia, and developed FN. The eligible patients were admitted and followed up with mortality as the primary outcome. A stepwise, multivariate logistic regression analysis was used to find predictors for mortality. RESULTS There were 203 patients met the study criteria. Of those, 14 patients died (6.89%). AML was the most common type of acute leukemia with FN (64.04%). There were five remaining factors in the final model: AML, FN at admission, prolong broad spectrum antibiotics, lower respiratory tract infection, and Aspergillosis. Only lower respiratory tract infection was significant with adjusted odds ratio of 7.794 (95% CI of 1.549, 39.212). The Hosmer-Lemeshow Chi square was 2.74 (p value 0.907). The lower respiratory tract infection group had higher proportions of Gram negative and fungus than the non-lower respiratory tract infection group; specifically E. coli (p 0.003), and Aspergillus (P < 0.001). CONCLUSIONS There were two independent predictors of mortality in acute leukemia patients with FN: septic shock and lower respiratory tract infection regardless of leukemia type or pathogen. E. coli and Aspergillus were more common in those with lower respiratory tract infection than those without. No specific pathogens were found in cases of septic shock.

Abstract
Event-free survival at 12 months (EFS12) is a surrogate endpoint for long-term outcomes in many histologic lymphoma subtypes. However, most reports have primarily investigated the implication of EFS12 in advanced-stage non-Hodgkin lymphoma (NHL). There are limited data regarding the significance of EFS12 in early-stage NHL. Herein, we evaluated the prognostic significance of EFS12 in patients with stage 1 diffuse large B-cell lymphoma (DLBCL). Out of 282 patients with stage 1 DLBCL who received intensive therapy, 227 (80.5%) achieved EFS12. The 4-year overall survival (OS) was 91.4% and 4.0% for patients who achieved and failed to achieve EFS12, respectively. Multivariable analyses demonstrated response to treatment and achievement of EFS12 as independent predictors for OS. In conclusion, our study demonstrated EFS12 as a powerful prognostic factor for stage 1 DLBCL. Further validation in more extensive prospective studies is warranted.

Abstract
Event free survival at 24 months (EFS24) has been described as a powerful predictor for outcome in several subtypes of B cell lymphoma. However, it was limitedly described in T cell lymphoma. We explored the implication of EFS24 as a predictor marker for peripheral T cell lymphoma (PTCL). We reviewed 293 systemic PTCL patients at 13 nationwide major university hospitals in Thailand from 2007 to 2014. The median event free survival (EFS) and overall survival (OS) of PTCL patients in our cohort was 16.3 and 27.7 months with corresponding 2-year EFS and 2-year OS of 45.8% and 51.9%, respectively. A total of 118 patients achieved EFS24 (no events during the first 24 mo). Patients who achieved EFS24 had better OS than patients who did not (2-y OS 92% vs 18.8%; HR, 0.1; P < .001). The standardized mortality ratio of patients achieving EFS24 was 18.7 (95% CI, 14.6-22.8). Multivariable analysis demonstrated performance status, histologic subtype, remission status, and EFS24 achievement as independent predictors for OS. Our study affirmed the value of EFS24 as a powerful prognostic factor for PTCL. Further validation in prospective study setting is warranted.

Abstract
INTRODUCTION Thalassemia-related complications are one of the main factors that increase morbidity and mortality in aging patients with thalassemia. This study was aimed to report the prevalence and clinical risk factors for the complications in thalassemia. METHODS A multi-center prospective cohort study was conducted in patients with thalassemia aged ≥10 years old. Thalassemia-related complications were heart failure, pulmonary hypertension, extramedullary hematopoiesis, endocrine disorders, infections, thrombosis and leg ulcers. The clinical parameters significantly associated with the complications were analyzed by logistic regression methods. RESULTS The prevalence of thalassemia-related complications was 60.5% in patients with transfusion-dependent thalassemia (TDT) and 43% in patients with non-transfusion-dependent thalassemia (NTDT). Splenectomy was statistically associated with complications in both TDT and NTDT patients (adjusted odds ratio (AOR) = 7.4, p-value = 0.0001 and AOR = 2.6, p-value = 0.001). Age ≥50 years old (AOR = 2.9, p-value = 0.04) and female gender (AOR = 0.5, p-value = 0.03) were statistically associated with the complications in patients with NTDT. CONCLUSION Nearly half of the patients in this cohort had disease-related complications. Splenectomy and advanced age were important factors for complication involvement. Early screening for the complications may reduce the morbidity and mortality in patients with thalassemia.

Abstract
BACKGROUND Paraspinal extramedullary hematopoiesis (EMH) is uncommon, but it is one of major complications of increased morbidity in patients with thalassemia. OBJECTIVE To develop a clinical risk score for predicting paraspinal extramedullary hematopoiesis in patients with thalassemia. MATERIAL AND METHOD A retrospective study was conducted in adult patients with thalassemia at Srinagarind Hospital, Khon Kaen University (KKU) and Udonthani Hospital, Thailand. Paraspinal EMH was defined as radiologic evidence of EMH foci with or without symptoms. The clinical parameters significantly associated with EMH were entered into the logistic regression model. The risk score was derived from the final model’s coefficients. A receiver-operating characteristic (ROC) curve was constructed to determine the area under the ROC curve and the cut-off point. RESULTS The KKU-EMH score included: 1) age greater than 25 year (2 points) and 2) thalassemic facie (3 points). Using the cut-off of 5 points, the score showed good discrimination with an area under the ROC curve of 0.83 (95% CI 0.76 to 0.90). CONCLUSION Advanced age and thalassemic facie are independent risk factors for paraspinal EMH in patients with thalassemia. The KKU-EMH score is a practical score. It can be used as a screening tool for paraspinal EMH in patients with β-thalassemia.

Abstract
INTRODUCTION Bacterial infection is one of the major causes of death in patients with thalassemia. Clinical predictive factors for severe bacterial infection were evaluated in patients with non-transfusion-dependent thalassemia (NTDT). METHODS A retrospective study was conducted of patients with NTDT aged ≥ 10 years at Srinagarind Hospital, Khon Kaen University, Thailand. Clinical characteristics and potential clinical risk factors for bacterial infection were collected. Risk factors for bacterial infection were evaluated by multivariate logistic regression analysis. RESULTS A severe bacterial infection was found in 11 of the total 211 patients with NTDT (5.2%). None of the clinical factors assessed was shown to be statistically associated with severe bacterial infection in patients with NTDT. However, three factors were demonstrated to be potential predictive factors for severe bacterial infection: time after splenectomy >10 years, deferoxamine therapy, and serum ferritin >1000 ng/ml. None of the patients died from infection. CONCLUSION The prevalence of bacterial infection in patients with NTDT was found to be moderate. Time after splenectomy >10 years, deferoxamine therapy, and iron overload may be clinical risk factors for severe bacterial infection in patients with NTDT. Bacterial infection should be recognized in splenectomized patients with NTDT, particularly those who have an iron overload.

Abstract
INTRODUCTION Pulmonary hypertension is one of the major complications in patients with non-transfusion-dependent thalassemia (NTDT). Patients with NTDT have distinct genetic subgroups. Therefore, the effects of different genotype groups on pulmonary hypertension risk in patients with NTDT were assessed. METHODS A cross-sectional study was conducted in patients with NTDT aged ≥ 10 yr old at Srinagarind University Hospital and Udonthani Hospital, Thailand. Pulmonary hypertension risk was defined as peak tricuspid regurgitation velocity > 2.9 m/s by trans-thoracic echocardiography. Clinical characteristics and laboratory data that literature has indicated as risk factors for pulmonary hypertension were collected. The effect of genotype group on pulmonary hypertension risk was evaluated by using multivariate logistic regression analysis. RESULTS Of 219 patients, pulmonary hypertension risk was found in 24 patients (10.96%). All patients were categorized into two groups according to genetic data that included: (i) β-thalassemia (139, 63.5%), (ii) α-thalassemia and combined α and β-thalassemia (80, 36.5%). Genotype groups were statistically and significantly associated with pulmonary hypertension risk based on the adjusted odds ratios after adjustment for other factors. Patients with β-thalassemia had a statistically significant higher risk for pulmonary hypertension risk (odds ratio = 9.47, P = 0.036) compared to patients with α-thalassemia and patients with combined α and β-thalassemia. CONCLUSION The genotype group is an independent risk factor for pulmonary hypertension in patients with NTDT. Echocardiography should be routinely recommended for all patients with β-thalassemia. Routine screening in patients with α-thalassemia and combined α and β-thalassemia, however, may not be necessary or should focus on the older population.

Abstract
Immune thrombocytopenic purpura (ITP) is the condition caused by increased platelet destruction and or decreased platelet production. Previous studies have demonstrated the association and efficacy of Helicobacter pylori (H. pylori) eradication therapy in patients with chronic ITP. Data in Thai patients, however, are limited. A prospective cross-sectional analytic study was conducted in adult patients with chronic ITP to determine the prevalence and clinical predictive factors of H. pylori infection and evaluate the efficacy of H. pylori eradication therapy. H. pylori-infected patients received eradication therapy (omeprazole 40 mg/day, clarithromycin 1000 mg/day, amoxicillin 2000 mg/day) for 2 weeks. The platelet counts at baseline and monthly for 6 months after the end of treatment were evaluated. Of the 25 patients, 9 patients (36%) had H.pylori infection. H. pylori infection is higher among women than men. There were two clinical factors included 1) relapsed ITP 2) response after the first-line treatment statistically proven to be associated with H. pylori infection with an odds ratio and p value of 7.7, p = 0.035 and ND (not determined due to small sample size), p < 0.001. Nearly 80% of infected patients had the platelet count response after eradication therapy with the median time to response of 4 months. The prevalence of H. pylori infection is modest in Thai adult patients with chronic ITP. A history of relapsed ITP and high quality of response after first-line treatment indicated H. pylori infection. Therefore, the urea breath test should be recommended in patients who have a relapsed ITP condition with a history of good response after first-line therapy.

Abstract
BACKGROUND Thalassemia is a common genetic disease in Thailand. However, current data on the impact and disease burden of thalassemia in Thailand remains limited. OBJECTIVE To determine the admission rate, OPD visit rate, mortality rate, hospital cost, length of hospital stay, blood transfusion rate and major complications rate in patients with thalassemia. MATERIAL AND METHOD The present study analyzed the data of inpatients and outpatients with a diagnosis of thalssemia according to ICD10 coded D56, D56.0, D56.1, D56.2, D56.3, D56.4, D56.8 and D56.9 which came from nationwide health financing schemes in the fiscal year 2010. RESULTS The overall admission rate and OPD visit rate were 154 and 562 per 100,000 populations and higher in children and adolescents. The overall mortality rate was 1.13 per 100,000 populations. The total healthcare cost was 744,998,997 Baht or US$ 23,486,727 per year. Blood transfusion rate was significantly higher among children and adolescents. The thalassemia-related complications commonly occurred at the second and the third decades of life. CONCLUSION The admission rate, OPD visit rate, blood transfusion rate were higher among children and adolescents. The total healthcare cost was high which was nearly 745 million Baht per year. The hospital cost, length of stay and major complications were increased with age.

Abstract
BACKGROUND Immune thrombocytopenic purpura (ITP) is not rare disease and it ispotentially fatal, particularly in patients with bleeding events which usually lead to hospitalization. Current data on the impact and disease burden of ITP in Thailand are lacking. OBJECTIVE To determine admission rate, mortality rate, hospital cost, length of hospital stay, co-morbidities, treatment and major bleeding events in patients with ITP. MATERIAL AND METHOD The authors analyzed the data of inpatients with a diagnosis of ITP according to ICD10 coded D69.3 which were retrieved from a nationwide health financing schemes in fiscal 2010. The data were analyzed by age groups, gender and health financing schemes. RESULTS The overall admission rate and mortality rate were 7.68 and 0.29 per 100,000 populations, respectively and increased with age. Women were predominant. Average hospital costs and hospital stays were 27,133 Baht and 6.7 days per admission, respectively and slightly higher among men than women. The most common co-morbidity was hypertension. Gastrointestinal hemorrhage was the most common bleeding event which was 21.5 per 1,000 admissions. Patients in the civil servant medical benefit scheme had the highest percentage of high cost treatment accessibility. CONCLUSION The admission rate, mortality rate and major bleeding events increased with age and was higher among women than men. Average hospital cost and length of hospital stay are higher in men than women. Common co-morbidities may be related to the treatment of ITP There are the differences in high-cost treatment accessibility between health insurance schemes.

Abstract
A 16-year-old Thai male presented with sudden onset severe epigastric and right upper quadrant pain, fever (39 degrees C), chills and malaise. He gave no history of underlying disease, migratory swelling or urticarial skin rash. He had a history of frequently eating raw pork. Physical examination revealed a soft abdomen with markedly tender hepatomegaly. His blood count showed extreme leukocytosis with hypereosinophilia. After admission he developed a non-productive cough with left sided chest pain, a chest x-ray showed a left pleural effusion. Serological findings were positive for Gnathostoma larval antigen but not Fasciola antigen. The patient recovered completely after albendazole treatment. His clinical presentation is compatible with abdominopulmonary hypereosinophilic syndrome or visceral larva gnathostomiasis. The presented case is interesting not only for physicians who work in endemic areas of gnathostomiasis but also for clinicians who work in travel medicine clinics in developed countries, to consider abdominopulmonary gnathostomiasis when patients present with the signs and symptoms of visceral larva migrans.

Abstract
Aplastic anemia has been linked to environmental exposures, from chemicals and medical drugs to infectious agents. The disease occurs more frequently in Asia than in the West, with incidence rates 2- to 3-fold higher. We report updated results of an epidemiologic study conducted in Thailand from 1989 to 2002, in which 541 patients and 2261 controls were enrolled. Exposures were determined by in-person interview. We observed significantly elevated relative risk estimates for benzene (3.5) and other solvents (2.0) and for sulfonamides (5.6), thiazides (3.8), and mebendazole (3.0). Chloramphenicol use was infrequent, and no significant association was observed. Agricultural pesticides were implicated in Khonkaen (northeastern Thailand). There were significant associations with organophosphates (2.1), DDT (6.7), and carbamates (7.4). We found significant risks for farmers exposed to ducks and geese (3.7) and a borderline association with animal fertilizer (2.1). There was a significant association in Khonkaen with drinking other than bottled or distilled water (2.8). Nonmedical needle exposure was associated in Bangkok and Khonkaen combined (3.8). Most striking was the large etiologic fraction in a rural region accounted for by animal exposures and drinking of water from sources such as wells, rural taps, and rainwater, consistent with an infectious etiology for many cases of aplastic anemia in Thailand.

Abstract
The authors reported a case of systemic lupus erythematosus (SLE) with an unusual presentation. The patient presented with acute febrile illness along with progressive pancytopenia related to increasing hemophagocytic activity of histiocytes in the bone marrow. Concomitant polyarthritis, myositis, nephritis, high titer of antinuclear factor (1:2,560) and positive test for anti-DNA antibody made him fit the diagnostic criteria of SLE. No definite evidence of associated infections was confirmed by bacteriologic, serologic and viral studies. He did not respond to empiric antibiotic therapy but dramatically responded to corticosteroid treatment. Therefore, diagnosis of acute lupus hemophagocytic syndrome was made. The clinical presentation, laboratory diagnosis, and management of the patient are discussed and the literature was reviewed and presented.

Abstract
The objective of this study was to determine the hematopoietic effects and toxicity of low-dose granulocyte colony-stimulating factor (G-CSF) in myelodysplastic syndrome (MDS) patients with neutropenia. Recombinant human G-CSF (Lenograstim) was administered by daily subcutaneous injection with an initial dosage of 0.5 microg/kg per day for 2 weeks. Patients not responding to the initial dosage received the escalated dosage, 1 to 2 microg/kg per day for 2 weeks. Eligibility criteria were the following: French-American-British disease classification subtype refractory anemia (RA), refractory anemia with ringed sideroblasts (RARS), or refractory anemia with excess blasts (RAEB) with an absolute neutrophil count (ANC) of <1.5 x 10(9)/L. Criteria indicating response to treatment were ANC of >1.5 x 10(9)/L and doubling of ANC on at least 2 occasions. Thirty-two MDS patients were recruited from 6 university hospitals. Eighteen patients had RA, 4 had RARS, and 10 had RAEB. Median age was 56.4 years (range, 28-87 years). Twenty-six patients (81.2%) had an increase in ANC from a median of 0.94+/-0.35 x 10(9)/L to 4.24+/-3.78 x 10(9)/L. Three of 6 patients who did not respond to the initial dosage responded to the escalated dosage of 1 microg/kg per day. Eighteen (81.8%) of 22 patients with RA or RARS responded compared with 8 (80%) of 10 patients with RAEB. The response rates in patients with ANCs of <0.5 x 10(9)/L. 0.5 to <1.0 x 10(9)/L, and 1.0 to 1.5 x 10(9)/L were 80%, 70%, and 88.2%, respectively. The side effects were minimal. No significant changes in hemoglobin levels or platelet counts were observed. In conclusion, low-dose G-CSF administered by subcutaneous injection is well tolerated and effective in improving neutropenia in MDS patients.

Abstract
The annual incidence of aplastic anemia has been determined in a rigorous and standardized epidemiologic study conducted in Thailand. A total of 374 cases were identified over a period of 3-6 years in three geographically defined and distinct regions of the country; Bangkok, Khonkaen in the northeast, and Songkla in the south. The incidence was 3.9 cases per million persons in Bangkok, 3.0 per million in Songkla, and 5.0 per million in Khonkaen. These rates are as high or higher than in any region of Europe or Israel as reported in the International Agranulocytosis and Aplastic Anemia Study, in which the methods and case definition were the same. Rates were stable over the course of the study. There were marked differences in incidence between northern and southern rural regions of Thailand, and among Bangkok suburbs. These differences, together with an unusual peak in the incidence among young people in Bangkok, suggest the possibility of occupational and environmental factors in the etiology of aplastic anemia.

Abstract
Agranulocytosis, a syndrome characterized by a marked reduction in circulating granulocytes, is strongly associated with medical drug use in Europe and the United States. Unregulated use of common pharmaceutical agents in developing countries has been suspected of causing large numbers of cases of agranulocytosis and deaths, especially among children. To elucidate the incidence and etiology of agranulocytosis in Thailand, a population-based case-control study of symptomatic agranulocytosis that resulted in hospital admission was conducted in Bangkok from 1990 to 1994. An attempt was also made to study the disease in Khonkaen (in northeastern Thailand) and Songkla (in southern Thailand), but there were insufficient cases in the latter regions, and the analysis was confined to subjects from Bangkok. In that region, the overall incidence of agranulocytosis was 0.8 per million per year; there were no deaths. As expected, the incidence was higher in females (0.9 per million), and it increased with age (4.3 per million beyond age 60). Among 25 cases and 529 controls the relative risk estimate for a combined category of all suspect drugs was 9.2 (95% confidence interval = 3.9-21), and the proportion of cases that could be attributed to drug use was 68%. For individual drugs and drug classes the data were sparse; within these limitations, the strongest association appeared to be with antithyroid drugs. One case and three controls were exposed to dipyrone, a drug known to cause agranulocytosis; with such scanty data the risk could not be evaluated. Exposure to pesticides or solvents was not associated with an increased risk. This is the first formal epidemiologic study of agranulocytosis in a developing country. As in the West, most cases are attributable to medical drug use. However, the incidence of agranulocytosis in Bangkok, and apparently, in Thailand as a whole, is unusually low, and the disease does not pose a public health risk.

Abstract
To gain more insight into the understanding of myelodysplastic syndromes (MDS) as they occur in Thailand, a retrospective clinicopathologic analysis was conducted in patients (age > 15 years) diagnosed as MDS from January 1992 to December 1996 at the five major medical centers in various geographic regions of the country. The central reviewers independently examined the bone marrow and peripheral blood smears of all the patients and classify the disease according to the French-British-American (FAB) classification. There were a total of 117 eligible patients. The median age of the patients was 56 years (range 16-86). The male:female ratio was 1:1. Thirty-two percent of the patients were younger than 40 years. The frequency of the FAB subtypes was RA/RARS, 54.7; RAEB, 23.1; CMML, 9.4; and RAEB-T, 12.8%. Anemia was the most common symptom presenting in 84.6% of the patients. In the 34 patients in whom the cytogenetics in the bone marrow were analysed, 44.1% revealed abnormalities. Of these, monosomy 7 and trisomy 8 were the most common aberration, each being detected in 26.7% of the patients. Transfusions were the main therapeutic modality in 80% of the patients. Kaplan-Meier analysis revealed a 5 year survival rate of 29% for the whole group with a median survival of 24 months. Twenty-five percent of the patients had progressed to acute myelogenous leukemia (AML) with a median time to disease-progression of 23 months. The median survival for RA/RARS, RAEB, CMML and RAEB-T were 58.4, 19.9, 10.7 and 8.7 months, respectively (P < 0.001). The stepwise Cox regression analysis revealed the percentage of blasts in the bone marrow as the only parameter significantly associated with survival and disease progression. On comparison with data from other countries, the age of Thai patients with MDS is considerably lower than the western population but is comparable to other asian countries. The distribution of the FAB subtypes and the survival of the patients are similar. The major prognostic features, however, lie in the percentage of blasts in the bone marrow rather than the degree of the observed cytopenia.

Abstract
OBJECTIVES A population-based case-control study was conducted to elucidate the incidence and etiology of aplastic anemia in Thailand. METHODS Case patients and hospital control patients were enrolled in three regions from 1989 to 1994; data were collected by interview. RESULTS Forty-six percent of 81 case patients and 19% of 295 control patients from Khonkaen were grain farmers (estimated relative risk [RR] = 2.7, 95% confidence interval [CI] = 1.4, 5.2). Sixteen percent of case patients and 6% of control patients used agricultural pesticides (estimated RR = 2.7, 95% CI = 1.1, 6.6). The association with grain farming remained among those not exposed to pesticides. In Songkla, 16% of 43 case patients and 2% of 181 control patients were grain farmers (crude RR estimate = 11, 95% CI = 3.4, 35). CONCLUSIONS The relation of aplastic anemia to grain farming may partly explain the high incidence of aplastic anemia in Thailand.

Abstract
BACKGROUND Aplastic anaemia is a severe blood dyscrasia that is more common in Thailand than in Western countries. Its a etiology remains poorly understood. METHODS A case-control study was conducted in Bangkok and two rural regions of Thailand. The effect of household pesticides was evaluated among 253 incident cases of aplastic anaemia and 1174 hospital controls. RESULTS A total of 54% of the cases and 61% of the controls were exposed 1-6 months previously. For most individual household pesticides and for groups classified according to chemical type (organophosphates, pyrethrins, and organochlorines), the relative risk (RR) estimates approximated 1.0; upper 95% confidence limits were below 2.0 for many comparisons. A significant association was observed for exposure to combination products containing dichlorvos and propoxur, with an overall RR estimate of 1.7 (95% confidence interval [CI]: 1.1-2.6); the estimate for regular use was 1.6 (95% CI: 0.9-2.9). CONCLUSIONS The absence of a higher risk for the regular use of dichlorvos/propoxur reduces the credibility of the apparent association, which could well have been an artefact of multiple comparisons. We conclude that most household pesticides used in Thailand do not appear to increase the risk of aplastic anaemia.

Abstract
From 1989 to 1994, a population-based, case-control study of aplastic anemia was conducted in Thailand, including the regions of Bangkok, Khonkaen in the northeast, and Songkla in the south. An annual incidence in Bangkok of 3.7 cases per million population, about twice as high as in Western countries, has been reported. To evaluate the etiologic role of drugs, 253 subjects were compared with 1,174 hospital controls. With multivariate adjustment for confounding, a significant association was identified for exposure 2 to 6 months before admission to thiazide diuretics (relative risk estimate 7.7; 1.5 to 40). There were crude associations with sulfonamides (relative risk estimate, 7.9; P = 0.004) and mebendazole (6.3; P = 0.03) (there were insufficient data for multivariate adjustment). Excess risks for the three drugs were in the range of 9 to 12 cases per million users. There was no significant association with chloramphenicol, although the multivariate relative-risk estimate was elevated (2.7; 0.7 to 10). Other drugs that have been reported to increase the risk of aplastic anemia, such as nonsteroidal anti-inflammatory drugs and anticonvulsants, were not commonly used. There were no associations with commonly used drugs, including benzodiazepines, antihistamines, oral contraceptives, and herbal preparations. For all associated drugs, the overall etiologic fraction (the proportion of cases attributable to an exposure) was 5%, compared with 25% in Europe and Israel. Drugs are uncommon causes of aplastic anemia in Thailand, and their use does not explain the relatively high incidence of the disease in that country.

Abstract
Aplastic anemia is more common in the Orient than in western countries, with an incidence in Thailand that is 2- to 3-fold higher than in Europe. Aplastic anemia after hepatitis is a well characterized clinical entity, and clinical hepatitis is also prevalent in the Far East. We performed a prospective case-control study to determine risk factors for aplastic anemia in Bangkok and two rural regions during 1989 to 1994. A total of 375 cases were identified, along with 1,174 hospital controls matched for age and sex. Historical data were collected by trained interviewers. Sera from a subset of cases (N = 177) and controls (N = 183) were tested for antibodies to hepatitis viruses A, B, and C and hepatitis B surface antigen. There was no evidence of association of aplastic anemia with hepatitis B or hepatitis C. Previous exposure to hepatitis A, as determined by immunoglobulin G (IgG) seropositivity, was significantly associated with aplastic anemia: the relative risk adjusted for confounding was 2.9 (95% confidence interval 1.2-6.7). The same association also existed for persons under age 25 years, in whom the prevalence of hepatitis A IgG was lower than in the total population. However, no patients showed evidence of recent infection with hepatitis A (immunoglobulin M [IgM] seropositivity). These results indicate that exposure to a hepatitis virus is a risk indicator for aplastic anemia in Thailand, and while itself unlikely to be etiologic, hepatitis A may be a surrogate marker for another enteric microbial agent.

Abstract
The relationship of socioeconomic status to the risk of aplastic anaemia was evaluated in a case-control study conducted in Bangkok and two rural regions of Thailand (Khonkaen and Songkla). Among 152 cases and 921 controls there were significant trends of increasing risk with decreasing years of education (P = 0.01) and total household income (P = 0.0001), after control for confounding. The relative risk estimate for those with monthly incomes of < 1500 baht (about $60 U.S.) was 3.9 (95% confidence interval 2.1-7.3) compared to those with monthly incomes of at least 5000 baht (about $200). The pattern of increasing risk with decreasing income was observed in all three regions, with significant trends in Bangkok (P = 0.004) and Khonkaen (P = 0.003). This finding may partly explain the high incidence of aplastic anaemia in Thailand. Low socioeconomic status may be a surrogate for one or more environmental factors that could cause aplastic anaemia, such as infectious pathogens or toxic exposures.

Abstract
The outcomes of 39 pregnancies in 36 idiopathic thrombocytopenic purpura (ITP) patients were analysed. Among the 36 pregnant patients, 23 had active ITP (platelet count < 100,000 per mm3), 12 had inactive ITP, during pregnancies, while one patient had active and inactive ITP during each of her two pregnancies. Maternal bleeding during delivery occurred more commonly in thrombocytopenic patients and was more frequent by cesarean section than by vaginal delivery. There was a 56 per cent incidence of neonatal thrombocytopenia. Maternal platelet count had no predictive value for neonatal thrombocytopenia. There was no serious bleeding among neonates born from thrombocytopenic mothers. In our experience, vaginal delivery was a relatively safe procedure for delivering small neonates from multiparous ITP mothers. Cesarean section should be used to deliver relatively big neonates especially from primigravida ITP mothers and splenectomy should be done at the same time.
