Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of T-cell lymphomas with a characteristic feature of subcutaneous nodules associated with hemophagocytic lymphohistiocytosis (HLH). Treatment options for SPTCL are mainly chemotherapy (CMT) or immunosuppressive agents with selection currently dependent on physician decisions. Outcomes between the 2 treatment remedies have not yet been comprehensively compared.

Despite several existing laboratory-based studies of hemoglobin (Hb) E (HBB:c.79 G > A)/ β (nucleotide (NT) -28 A > G) (HBB:c.-78 A > G) -thalassemia, no reports have ever provided clinical severity information as well as dependency of blood transfusion.

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.

The study aimed to identify essential phenotype-modulating factors among the pre-existence of several important ones and clarify their measurable impact on the clinical severity of hemoglobin (Hb) E/β-thalassemia in a community-recruited population analysis. This prospective study was designed to compare modifiers between community- (less or no symptoms) and hospital-recruited individuals with Hb E/β-thalassemia. The formerly included couples previously assessed for prenatal thalassemia at-risk status at 42 community and 7 referral hospitals in Thailand through on-site investigations between June 2020 and December 2021.

Article Synopsis
  • Relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) is tough to treat, and there's a need for better therapies; polatuzumab vedotin (Pola), combined with bendamustine-rituximab (BR), has recently been approved for patients.
  • A study in Thailand included 35 patients treated with Pola, showing a 62.8% overall response rate (ORR) and survival outcomes better than 180 patients receiving non-Pola therapies.
  • Despite some serious adverse events reported, they were manageable, indicating that Pola-based treatment could be a promising option for R/R DLBCL patients with limited alternatives.

In diabetes patients, urban lifestyle has been concerned as one of the risk factors for peripheral arterial disease (PAD). The aims of this study were to find out the prevalence and associated risk factors of PAD in type 2 diabetes patients who live in a non-urban community area. A total of 885 participants with type 2 diabetes mellitus were enrolled from six primary care units in the health network centered at Naresuan University Hospital, Phitsanulok, between May and June 2018.

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.

Objective: To assess the outcome of a thalassemia screening program at community hospitals by determining the proportion of at-risk couples able to obtain a prenatal diagnosis (PND) in relation to gestational age (GA).

Methods: We accessed records documenting prenatal screening for thalassemia in lower northern Thailand between January 2014 and December 2016. The proportion of at-risk pregnancies able to obtain a PND was determined and median GAs at the time of at-risk notification were compared.

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).

Introduction: Peripheral T cell NHL (PTCL) and natural killer/T cell NHL (NKTCL) are relatively rare disorders. Data on clinical presentation, treatment and outcome are limited especially in older age groups.

Methods: We identified 127 patients with PTCL and NKTCL, excluding cutaneous T/NK cell lymphoma, aged over 60 years old from Thailand nationwide multicenter registry.

Prevalence of cardiac and liver iron overload in patients with thalassemia in real-world practice may vary among different regions especially in the era of widely-used iron chelation therapy. The aim of this study was to determine the prevalence of cardiac and liver iron overload in and the management patterns of patients with thalassemia in real-world practice in Thailand. We established a multicenter registry for patients with thalassemia who underwent magnetic resonance imaging (MRI) as part of their clinical evaluation.

Systemic reports on the descriptive epidemiology of non-Hodgkin lymphoma (NHL) from Southeast Asia are scarce. A nationwide multi-institutional registry was conducted to compare the histopathology, clinical features, and survival of Thai adult patients with NHL using large registries, especially those from Far East Asia (FEA). Using a web-based registry system, 13 major medical centers from the 4 geographic regions of Thailand prospectively collected, from 2007 to 2014, the diagnostic pathology, according to the World Health Organization classification, 2008, clinical features and survival of 4056 patients who were newly diagnosed with NHL.

Objectives: For beta thalassemia control program in pregnancy, mass screening of the carrier state by determination of the hemoglobin (Hb) A and Hb E proportions and mutation analysis is a preferred method for making prenatal diagnoses. Q Sepharose micro-column chromatography, developed for the determination of Hb A and Hb E for screening purposes, was compared with high performance liquid chromatography (HPLC) to ascertain its relative accuracy and reliability.

Design And Methods: Results using Q Sepharose micro-column chromatography in 350 blood specimens, including 50 samples genetically proven to be beta thalassemia heterozygotes, were compared to HPLC for validation.

Secondary central nervous system (CNS) relapse is a serious and fatal complication of diffuse large B cell lymphoma (DLBCL). Data on secondary CNS (SCNS) relapse were mostly obtained from western countries with limited data from developing countries. We analyzed the data of 2034 newly diagnosed DLBCL patients enrolled into the multi-center registry under Thai Lymphoma Study Group from setting.

Background And Objectives: In newborns and infants during their first year of life, there is a dynamic change in the fraction of hemoglobin (Hb). To apply Hb analysis as a phenotypic diagnosis of thalassemia in newborns and infants, we need normal values of each Hb fraction for reference.

Methods: Seventeen cord bloods from normal deliveries were collected for analysis.

A bone marrow transplant (BMT) is one kind of standard treatment modality in advanced hemato-oncology. In order to set up a BMT unit, one of the important steps before starting a clinical program is to evaluate the cryopreservation procedure for stem cell storage. Twenty one bags of buffy coat were used to be the testing specimens.

Background And Objective: β-Thalassaemia is a major public health problem in Thailand. Use of appropriate iron-chelating agents could prevent thalassaemia-related complications, which are costly to the healthcare system. This study aimed to evaluate the cost effectiveness of deferoxamine (DFO), deferiprone (DFP) and deferasirox (DFX) in Thai transfusion-dependent β-thalassaemia patients from the societal perspective.

Objective: The incidence and etiologies of hospital-acquired anemia has not been well defined A prospective study was conducted to determine the incidence and etiologies of hospital-acquired anemia developed in patients admitted in the medical ward of a tertiary care university hospital.

Material And Method: All non-anemic (hemoglobin (Hb) > or = 13 g/dl in male, > or = 12 g/dl in female) patients who were admitted to the general medical wards for at least 1 week, between March 2001 to October 2001, were included in the present study. Outcome of interest was anemia developed during hospital stay.
