Hematological Profile with Peripheral Blood Smear Morphology of Admitted COVID-19 Infected Patients: A Study at a COVID Dedicated Hospital in Kashmir.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection started in Wuhan, China, and spread to the rest of the world to become a pandemic affecting over 385 million people throughout the world to date. Coronavirus disease 2019 (COVID-19) is primarily started as a respiratory tract infection. Recent studies indicate that it should be regarded as a systemic disease involving multiple systems including the hematopoietic system. Complete blood count and its parameters are important investigative tools in its prognosis. However, very few studies highlight the importance of peripheral blood cell morphology in this disease. AIM: To study the hematological parameters (complete blood count and peripheral blood film) of COVID-19-positive patients and to compare the hematological parameters of those admitted in intensive care units (ICUs) with those admitted in non-ICUs of the hospitals. MATERIALS AND METHODS: This retrospective study was carried out at a COVID-19 dedicated tertiary care center over a period of 3 months from July 2020 to September 2020. In our study, all 79 patients had complete blood counts performed at the time of admission. Complete blood count was repeated during the hospital stay for all severe cases. The data which provided information on the age and gender of each patient were obtained from the Laboratory Information System (LIS) of the hospital. RESULTS: The mean age of our study group was 46.05 years. Out of 79 cases, lymphopenia was seen in 16.5% with five patients presenting with severe lymphopenia (<0.5 × 109 /L). All the patients that required ICU care presented with moderate to severe lymphopenia. The patients in the ICU setting showed significant neutrophilia (mean 14.16 × 109 /L) on follow-up complete blood count. Thrombocytopenia was observed in 35.3% of cases. It was observed that the mean neutrophil- lymphocyte ratio was higher in ICU admitted patients as compared to the non-ICU admitted patients. Among the ICU patients, 80% showed a neutrophil-lymphocyte ratio above the baseline cutoff (3.1). A wide array of morphological changes were observed in the peripheral blood smear including toxic-like granules in neutrophils, fetus-like C-shaped nucleus, lymphoplasmacytoid cells, bizarre cells, and apoptotic cells. CONCLUSION: The study highlights that at the time of admission older age, decreased lymphocyte count, and raised neutrophil-lymphocyte ratio were closely associated with ICU admissions. Also, the morphological changes in peripheral blood film reveal atypical changes predominantly in the white blood cell (WBC) lineage.

Diagnosis and Management of Diffuse Large B-Cell Lymphoma: Society of Medical Oncology, Pakistan Society of Hematology, and Pakistan Society of Clinical Oncology Joint Clinical Practice Guideline.

Diffuse large B-cell lymphoma (DLBCL) is the commonest non-Hodgkin lymphoma encountered by hematopathologists and oncologists. Management guidelines for DLBCL are developed and published by countries with high income and do not cater for practical challenges faced in resource-constrained settings. This report by a multidisciplinary panel of experts from Pakistan is on behalf of three major national cancer societies: Society of Medical Oncology Pakistan, Pakistan Society of Hematology, and Pakistan Society of Clinical Oncology. The aim is to develop a practical and standardized guideline for managing DLBCL in Pakistan, keeping in view local challenges, which are similar across most of the low- and middle-income countries across the globe. Modified Delphi methodology was used to develop consensus guidelines. Guidelines questions were drafted, and meetings were convened by a steering committee to develop initial recommendations on the basis of local challenges and review of the literature. A consensus panel reviewed the initial draft recommendations and rated the guidelines on a five-point Likert scale; recommendations achieving more than 75% consensus were accepted. Resource grouping initially suggested by Breast Health Global Initiative was applied for resource stratification into basic, limited, and enhanced resource settings. The panel generated consensus ratings for 35 questions of interest and concluded that diagnosis and treatment recommendations in resource-constrained settings need to be based on available resources and management expertise.

Left Ventricular Systolic Dysfunction Predicted By Early Troponin I Release After Anthracycline Based Chemotherapy In Breast Cancer Patients.

BACKGROUND: Anthracyclines are one of the most effective chemotherapeutic agents in management of Breast cancer, however Anthracycline induced cardiotoxicity remains a matter of special concern. Detection of early toxicity by use of biomarkers like Troponins has been the focus of interest in recent years. We measured Troponin I levels after chemotherapy with anthracyclines and correlated it with ECG, Echocardiography and clinical findings. METHODS: Patients with early Breast cancer eligible for chemotherapy were included in the study. All patients underwent clinical evaluation, Left Ventricular Ejection Fraction (LVEF) measurement by echocardiography at baseline and every 03 monthly for first year. Serum samples for TNI were obtained immediately after chemotherapy and after 24 hrs. RESULTS: A total of 82 patients (all females) were included in the study. Median age was 47 (range 30-64) years. Anthracycline mediated cardiotoxicity occurred in 6 patients (7%) and was more frequent in patients with TNI elevation (p<0.001). Five patients (83%) recovered from cardiotoxicity. At multivariate analysis, TNI elevation was the only independent predictor of cardiotoxicity (95% CI 0.0007879-0.2821) and of lack of LVEF recovery (95% CI 0.002484 to 1.680). CONCLUSIONS: Measurements of Trop I levels after Anthracyclines can be useful in detecting early cardiotoxicity and tailoring further therapy.

Clinical predictors of anticipatory emesis in patients treated with chemotherapy at a tertiary care cancer hospital.

OBJECTIVE: To determine the clinical predictors of anticipatory emesis in patients treated with chemotherapy at a tertiary care cancer hospital. METHODS: This was a cross-sectional study conducted on 200 patients undergoing first line chemotherapy with minimum of two cycles at inpatient department and chemotherapy bay of Shaukat Khanum Memorial Cancer Hospital and Research Centre Pakistan. Anticipatory nausea and vomiting develops before administration of chemotherapy. Clinical signs and symptoms in patients with or without anticipatory emesis were compared using chi square test statistics. RESULTS: The mean age of the study participants was 36.68 years (SD±12.23). The mean numbers of chemotherapy cycles administered were 3.23 (SD±1.2). Chemotherapy related nausea and vomiting was experienced by 188 (94%) patients and anticipatory nausea vomiting was reported in 90 (45%) of patients. Greater proportions of patients with anticipatory emesis were females. Fourteen (15.5%) p-value=0.031 patients with anticipatory emesis had history of anxiety and depression. Fifty nine (65.5%) p-value =< 0.0001 patients with anticipatory emesis had severe nausea after last chemotherapy cycle. Forty six (51.11%) p=<0.0001 patients had motion sickness. CONCLUSION: Female gender, history of motion sickness, anxiety and depression, severe nausea and vomiting experienced in pervious cycle of chemotherapy were clinical predictors of anticipatory nausea and vomiting.

Piperacillin-tazobactam as a cost effective monotherapy in febrile neutropenia.

BACKGROUND: Fever in neutropenic patient is a medical emergency. Timely intervention with antibiotics has been demonstrated to be effective. We assessed Piperacillin-Tazobactem as a cost effective mono-therapy in solid malignancy patients in our institution in relation to dual antibiotic therapy and other monotherapies. METHODS: This study was conducted to determine the efficacy, and cost effectiveness of Piperacillin-Tazobactem as monotherapy in febrile neutropenia. Total 150 patients with chemotherapy induced febrile neutropenia were selected. Piperacillin-Tazobactem was given intravenously 4500 mg every 6 hour. Outcome was assessed as success and failure. Success was defined as afebrile for four consecutive days, clearance of signs of infection, no new cultures, and no recurrence of primary infection after completion of therapy. Failure was defined as modification or addition of antibiotic due to clinical deterioration, cultured organism resistant to Piperacillin-Tazobactem and Death. RESULTS: The mean age was 43 years, 31% males and 69% were females. Out of total 150 patients, 73 patients were of breast carcinoma. There were 143 patients with negative blood cultures, and 7 patients with positive blood cultures, out of which 3 patients were resistant to Piperacillin-Tazobactem. Success was achieved in 83.3% of total patients. Daily cost of Piperacillin-Tazobactem was much less in relation to other monotherapies and dual antibiotic therapy including Gentamicin. None of the patient had adverse effects of Piperacillin-Tazobactem. CONCLUSION: We concluded that Piperacillin-Tazobactem is a safe, well tolerated as well as cost effective monotherapy in patient with febrile neutropenia with solid cancers. Only two percent organisms were resistant to Pipercillin-Tazobactam.
