ABSTRACT
Background. Survival of myeloma patients has improved considerably in the past decade. However, limited data are available on their long-term outcome. We analysed the data of 225 consecutive patients who underwent autologous stem cell transplantation (ASCT) at our centre. Methods. Between April 1990 and December 2013, a total of 225 patients with multiple myeloma (median age 53 years, range 27–67 years, 69.3% men) underwent ASCT. High-dose melphalan 200 mg/m2 was used for conditioning. Before transplant, the patients received induction therapy with novel agents (thalidomide and dexamethasone, or lenalidomide and dexamethasone, or bortezomib and dexamethasone); or vincristine, doxorubicin, dexamethasone; or alkylating agents (vincristine, melphalan, cyclophosphamide and prednisolone; or melphalan and prednisolone). The response to transplant was evaluated using the European Bone Marrow Transplant criteria, and an intention-to-treat analysis was done. Results. Four-fifths (79.6%) of our patients had Durie Salmon Stage (DSS) IIIA and nearly a quarter (24%) of them had International Stage III disease. Before the transplant, 80.4% of patients had chemosensitive disease. The median interval from diagnosis to transplant was 10 months (range 2–128 months). Following ASCT, 197 (87.5%) patients responded. Complete response was obtained in 54.7%, very good partial response in 19% and partial response in 13.8%. At a median follow-up of 90 months (range 18–266 months), the median progression-free survival (PFS) and overall survival (OS) were 32 and 85.5 months, respectively. The estimated PFS and OS at 10 years were 29.7% and 43.6%, respectively. On multivariate analysis, the presence of extramedullary disease (HR 3.05, p<0.001), and ISS III (HR 0.50, p<0.02)
ABSTRACT
OBJECTIVE: This prospective study was conducted to evaluate the role of hemoglobin level, as a risk factor for Lower Respiratory Tract Infections in children (LRTI). METHODS: 100 children who came to the outpatient department for LRTI were included in the study. Age and sex-matched 100 children, not having any respiratory illness, were taken as control. They were subjected to complete blood count (CBC),C-reactive protein estimation (CRP), Mantoux test and X-ray chest. Peripheral smear, serum ferritin and serum iron binding capacity were done for all anemic children. Results. Radiological evidence of pneumonia was present in 63 children(63%).Hyper inflated lungs were seen in 27 (27%). Mantoux was positive in 22 children (22%) of study group and none among control group. CRP > 6 mg/L was noted in 45 children (45%) of study group and 14 (14%) of control group. Seventy four of study group (74 %) and 33 of control group (33%) had anemia. Of the anemic children, 60 (60%) had iron deficiency,10 (10%) chronic inflammation and 4 (4%) had hemolytic anemia. These values were 30 (30%), 2 (2%) and 1 (1%)respectively for control group. Low hemoglobin level due to whatever etiology, was a risk factor (p=0.000). CONCLUSION: Anemic children were 5.75 times more susceptible to LRTI compared to the control group. Prevention of anemia, due to whatever etiology, will reduce the incidence of LRTI.
