Background and Objective: Disease activity score 28 (DAS28) for rheumatoid arthritis (RA) is the commonly used DAS; it relies on clinical parameters that could be subjective. This work aimed to create a more accurate DAS for RA and assess its validity. Patients and Methods: The study included 98 RA patients and 53 matched controls; they were interviewed, clinically examined, their visual analogue scales (VAS) were reported, and then blood samples were withdrawn for erythrocyte sedimentation rate (ESR), complete blood count (CBC), and C-reactive protein (CRP). Platelet indices (PIs) were obtained from the CBC including Plt (platelet count), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT). DAS28 was calculated for each patient using RheumaHelper mobile software. Minitab Statistical Package® and SPSS v20 software were used for data analysis. Results and Conclusions: Results revealed perfect matching between patients and controls as regarding age and gender. ESR, CRP and PDW were significantly higher in patients than controls; also positive correlations were detected among these variables. A new DAS for RA was developed; ESR, CRP, PDW and MPV were the components for this index. Further analyses showed that this new score was significantly higher in patients than controls and correlated with DAS28 of the patients. Furthermore the new score could identify RA patients from healthy subjects (cut off value < − 0.79) and stratified RA patients according to their disease activity into low, intermediate, high, or in remission. Conclusively, we developed a more precise, easily obtained new DAS for RA. This new DAS has both diagnostic/prognostic values in patients with RA.

Background and objectives: IL27 and IL35 are regulatory T cells (T-regs) related cytokines; they were accused in eukemogenesis of acute myeloid leukemia (AML). This study aimed to assess the expression of these cytokines in de novo AML and investigate their role as biomarkers. Subjects and methods: Seventy newly diagnosed patients with primary AML and 30 matched healthy volunteers were recruited. AML diagnosis was confirmed with flowcytometric and immunophenotypic analyses, while ELISA was used to assess serum levels of IL27 and IL35 in patients and controls. Receiver operating characteristic curve analysis was used to estimate IL27 and IL35 optimum cutoff values for predicting AML. Results: Serum levels of both cytokines were significantly higher in AML patients than controls (P43, AUC (0.926) with a sensitivity 74% and specificity 96.6% (P27.8, AUC (0.972) with 88% and 98% sensitivity and specificity, respectively (P<0.001). Conclusion: Conclusively, this study proved that IL27and IL35 could identify AML patients from healthy subjects, and their overexpression denotes poor prognosis. Based on the simplicity and wide availability of their detection technique we recommend the inclusion of IL27 and IL35 in the diagnostic/prognostic workup of AML; however, further longitudinal research is needed to prove their exact prognostic value.

Background: The distress thermometer (DT) is an effective tool for identifying distress among cancer patients worldwide. However, DT has not been studied in Egyptian patients. We aimed to study the prevalence of distress among Egyptian patients with different types of cancers using DT. Methods: A total of 550 patients with newly diagnosed hematological and solid cancers who were followed up at 3 Oncology Centers in Egypt were enrolled. They completed a sociodemographic and clinical status questionnaire, the DT and the Problem List (PL) scale. Results: At a DT cut-off score of ≥4, 46% of patients had significant distress, which was related to the tumor site and stage. The most frequent problems reported were treatment decision (64.4%), worry (47%), and fears (44.5%). In univariate logistic regression analysis, participants who had significant distress described 23 out of 36 problems in the practical, family, emotional, and physical areas. After adjustment to sociodemographic and clinical characteristics, multivariable analysis confirmed that insurance, depression, fear, sadness, worry, loss of interest in usual activity, and sleep were independent factors associated with significant distress in cancer patients. Conclusions: Almost half of Egyptian patients newly diagnosed with cancer reported significant distress. Those who had significant distress described extra problems in the practical, family, emotional, and physical areas. We recommend the routine use of DT for screening Egyptian patients with cancer, as well as the involvement of the psycho-oncology and social services, at the time of their initial diagnosis.

The sickle cell trait (SCT) disorder possesses a clinical heterogeneity ranging from a symptomless condition to sudden death. This study aimed to develop a diagnostic approach that helps the characterization and identification of SCT from normal subjects and sickle cell disease (SCD) patients, and to assess its severity. Sixty controls, 24 SCD patients and 31 SCT subjects were assessed clinically, radiologically and by laboratory investigations. Of the SCT subjects, 12.8% were symptomatic (3.2% anemic, 6.4% hemolytic crisis, and 3.2% painful crises). Anemia was normocytic in 66.6%, and normochromic and polychromatic in 33.4%. Significantly lower red blood cells (RBCs), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), hematocrit (Hct), Shine and Lal index (SL), and hemoglobin A (Hb A), and higher mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), Ricerca index (RI), and Huber-Herklotz index (HH) were found in SCT subjects compared with the controls. Hb A and hemoglobin S (Hb S) were excellent in discriminating SCT from SCD (cut-off for SCT > 50% and < 40%) followed by Hct, MCHC, Hb, Green and King index (GK), and England and Fraser index (EF) (cut-off for SCT > 33%, > 32, > 11, < 71, and < 10, respectively). Radiologically normal findings were detected in 87% of SCT subjects; they had nearly normal liver and renal function tests (except one case each). A schematic diagnostic paradigm for SCT was proposed. This study allowed understanding of SCT in various aspects, i.e., clinical, hematological, biochemical and radiological. Thus, it could help prevention of the Hb S variant disorder and proper management of carriers. This might be applied in pre-marital screening, particularly in those with family history of Hb S disorder.

Background and objectives: Myeloid leukemias (MLs) are clonal stem cell disorders affecting myeloid lineage cells. Advances in cytogenetic and molecular studies partially disclosed the mystery about risk factors and pathophysiology of MLs. Regarding incidence, risk factors, response to treatment, and overall survival of patients, research showed differences among different countries. However, the Western registry data are the basis for the documented description of MLs in medical textbooks. This research aimed to study MLs in Middle Eastern health centers. Egypt has the highest population in the Middle East; furthermore, 96.6% of the population is native Egyptians; accordingly the study focused on Egypt. Patients and methods: Data of 468 patients with MLs were collected from hospital records at two big tertiary health centers. They were grouped into group 1 (chronic myeloid leukemia, CML) and group 2 (acute myeloid leukemia, AML); the latter was subgrouped into 2a (primary AML) and 2b (secondary AML). Results and conclusions: The median age of patients was 43 years; males predominate in group 2a and females in groups 1 and 2b. 37.2% of group 1 patients were treated with Gleevec. Hematopoietic stem cell transplantation was planned for only 5% of group 2 and 18% relapsed. Of groups 1 and 2 patients, 25% and 12%, respectively, stopped follow up, and 15% and 35% died. ORR and overall survival were 53%, 27% and 7%, 0.4% for groups 1 and 2, respectively. Conclusively, this study showed a young age of ML patients, with female predominance in CML, and poor outcome. This reflected racial, ethnic and risk factor differences in incidence of MLs.

Background: Acute myeloid leukemia (AML) is a hematopoietic stem cell disorder that carries very poor prognosis. Understanding molecular basis of AML leukemogenesis could lead to the emergence of effective targeted therapies for AML. AML bearing nucleophosmin (NPM) gene mutation has distinct features. This study was conducted to investigate the role of mutated (m) NPM in pathogenesis of de novo AML through studying its contribution in proliferation of AML cell line cells. Methods: Two types of human leukemia cell lines were used. One of them was a model for AMLs with mNPM and the other for AMLs with wild type (wt) NPM. Assessment of the proliferative role of mNPM in AML was carried out using cell culture and viability studies. The obtained results were reaffirmed by immunocytochemical and immunoblotting techniques. Results: Analysis of results was done with the appropriate computer software. It showed higher proliferative potential of cells with mNPM compared to those bearing wtNPM only. Furthermore, the immunocytochemical studies demonstrated subcellular localization of NPM isoforms during various phases of mitosis. Mitosis was associated with cytoplasmic translocation of wtNPM in certain phases, while localization of mNPM remained unchanged throughout the cell cycle. Results of immunoblotting showed little or no change in protein expression of either NPM moieties during mitosis. Conclusions: The current study demonstrated important contribution of NPM gene mutation in enhancing proliferation of AML cell lines. These results confirmed the role of mNPM in AML leukemogenesis, and highlighted the importance of targeting mNPM in new evolving AML therapies.
