To Evaluate Platelet Indices, Platelet to Lymphocyte Ratio and Neutrophil to Lymphocyte Ratio as Prognostic and Risk Factors in Patients with Coronary Artery Disease.

To evaluate platelet indices, platelet to lymphocyte ratio and neutrophil to lymphocyte ratio as prognostic and risk factors in patients with coronary artery disease Introduction: cardiovascular diseases have 12 million deaths annually which is one of the commonest causes of death globally. Platelet parameters like Mean platelet volume (MPV), platelet distribution width (PDW) and WBC parameters like Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio(PLR) have recently been emerging as a new prognostic marker in number of coronary artery disease (CAD) with limited studies to explore their utility. AIMS AND OBJECTIVES: this study aimed to evaluate MPV, P-LCR, PDW, PLR, NLR and GRACE risk score in CAD patients. MATERIAL AND METHODS: this descriptive cross-sectional study was done in 330 cases of CAD and 200 healthy controls were studied.MPV, platelet-large cell ratio (P-LCR), PLR, NLR and PDW of patients were analyzed. RESULTS: In our study, 245 were males and 85 were females. Mean PDW, MPV, Mean PLCR, Mean NLR was significantly higher in CAD cases as compared to controls (p value < 0.05). Mean PLR was not significantly different in CAD cases and controls. MPV was more associated risk predictor of CAD (8.98 times) followed by NLR (2.79 times), PDW (1.53 times) and PLCR (1.02 times). DISCUSSION AND CONCLUSION: platelet indices, NLR and PLR are simple cost effective parameters and in future these might be useful adjuvant tests in conjunction with conventional biochemical cardiac markers in early prediction of risk of CAD in patients admitted to hospital and can guide clinicians in assessing the prognosis on short and long term follow up of these patients in terms of morbidity and mortality.

A retrospective study to assess the impact of ABO incompatibility on outcomes of allogeneic peripheral blood stem cell transplants at a tertiary care hospital in Western Maharashtra.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) has emerged as a curative measure for life-threatening hematological disorders. It can be autologous or allogeneic depending on the disease characteristics. Providing transfusion support to the transplant patients can be challenging, especially in AB-mismatched allogeneic HSCT. In this study, we investigated the impact of ABO incompatibility in patients undergoing allogeneic HSCT. MATERIALS AND METHODS: A retrospective review was conducted in 76 patients with hematological diseases who underwent allogeneic HSCT. Transfusion requirements, engraftment profile, incidence of graft versus host disease (GvHD), and mortality for a period of 1 year were analyzed. RESULTS: ABO incompatibility between donor and the patient did not significantly affect the neutrophil and platelet (PLT) engraftment time (P = 0.389, 0.349, respectively), packed red blood cells transfusion requirement, and duration of initial hospital stay. However, patients of ABO-incompatible HSCT received more PLT transfusions posttransplant which was statistically significant. 29.1% of ABO compatible and 16.7% incompatible HSCT patients developed GVHD. Mortality rates in the two groups were 16.7% and 8.3%, respectively. However, differences in both the parameters were not statistically significant. CONCLUSION: Our study showed that ABO incompatibility does not significantly affect the outcome and should not be a limiting factor for selection of donor. Donor availability and human leukocyte antigen (HLA) matching remain the critical selection criteria.

Successful therapeutic plasma exchange in a patient with Morvan syndrome.

Morvan syndrome is a rare autoimmune disorder, characterized by hyperexcitability of both central and peripheral nervous systems, accompanied by autonomic dysfunction and hallucinations.[1] Therapeutic plasma exchange (TPE) has been found to be an effective mode of treatment for this disease, but there is limited literature supporting the same.[2] A 26-year-old male was admitted to our hospital and diagnosed with a case of Morvan syndrome, based on the clinical picture and laboratory findings. When standard drug therapy failed to show any improvement, a decision to carry out TPE was taken. The case presented with many peculiar challenges, mostly due to autonomic instability and hyperkinesia experienced by the patient while carrying out the procedure. All these challenges were diligently addressed and managed promptly. Clinical signs of improvement were evident from the 2nd TPE and by the time fifth TPE had finished, the patient was able to perform activities such as walking with support. His autonomic dysfunction and behavioral abnormalities had significantly subsided. This case report highlights the possible effectiveness of TPE in the management of a rare disease such as Morvan syndrome and appropriate application of basic principles and criteria for the use of TPE in cases where limited literature is available.

Single Dose Preemptive Plerixafor for Stem Cell Mobilization for ASCT After Lenalidomide Based Therapy in Multiple Myeloma: Impact in Resource Limited Setting.

Peripheral blood stem cell mobilization with cytokines for autologous stem cell transplant in multiple myeloma is adversely affected by initial induction therapy consisting of either Lenalidomide or cytotoxic drugs, with failure rates of up to 45%. The use of Plerixafor with G-CSF for PBSC mobilisation significantly improves the chances of a successful mobilization. Plerixafor is a costly therapy and increases the overall costs of ASCT which can affect the number of patients being taken up for ASCT in resource limited settings. We prospectively studied the impact of single dose preemptive Plerixafor for PBSC mobilization in patients with prior Lenalidomide exposure. 26 patients who had received Lenalidomide based induction protocol underwent PBSC mobilisation during the study period with G-CSF 10 µg/kg/day SC for 4 days and single dose preemptive Plerixafor 240 µg/kg SC stat 11 h before the scheduled PB stem cell harvest on D5, based on a D4 PB CD34+ counts of <20/µL. A median of 07 cycles of Lenalidomide based combination therapy was used for induction therapy prior to ASCT. 84% patients underwent successful mobilization with one sitting of stem cell harvest post a single dose of Inj Plerixafor. 7.6% patients failed to mobilise the predefined minimum cell dose of CD34 and could not be taken up for ASCT. The median CD34% of the harvest bag sample was 0.33% (0.1-0.97%). Injection site erythema (34%), paresthesia's (34%) and nausea (30%) were the commonest adverse events reported post Inj Plerixafor. We did a real-world cost analysis for a resource limited setting for PBSC mobilization and found significant cost savings for the preemptive Plerixafor group.

Patterns of acquired bleeding disorders in a tertiary care hospital.

Bleeding disorders constitute a large proportion of referrals to hematology departments. Worldwide, acquired causes of bleeding are commoner than inherited ones. To identify the spectrum of these disorders, we evaluated all referrals for bleeding encountered in this tertiary care centre over a one-year period. Of the total 1342 cases, 1040 (77.5%) had underlying exclusively acquired causes, whereas inherited causes constituted 302 cases (22.5%). Amongst acquired causes, disseminated intravascular coagulation was seen in 297 (28.6%), hepatic coagulopathy in 218 (20.9%), neurosurgical causes (intracranial bleeds) in 154 (14.8%), malignancy in 89 (8.6%), and miscellaneous multiple acquired causes including those due to anticoagulant drug overdose in 282 patients (27.1%). Referrals for isolated prolonged prothrombin time or thrombocytopenia were common, but were excluded from this study because not all presented with bleeding. Prompt laboratory work-up and precise identification of acquired causes of bleeding is the key to planning appropriate patient management including transfusion support.
