Hematological and biochemical parameters as diagnostic and prognostic markers in SARS-COV-2 infected patients of Pakistan: a retrospective comparative analysis.

Objectives: This study was conducted to investigate alteration in blood parameters and their association with the presence, severity, and mortality of COVID-19 patients as the data on hematological abnormalities associated with the Pakistani COVID-19 patients is limited.Methodology: A double-centered, hospital-based comparative retrospective case study was conducted, to include all the admitted patients (n = 317) having COVID-19 Polymerase chain reaction (PCR) positive. The control group (n = 157) tested negative for COVID-19.Results: Of 317 admitted cases, the majority were males n = 198 (62.5%). Associated comorbidities, lower lymphocytes, platelets, and higher White blood cells, neutrophil, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were found in COVID-19 cases as compared to healthy controls (p < 0.001 for all). The biochemical parameters of cases including Ferritin, D-Dimer, CRP, IL-6, LDH, ALT, AST, and APTT also showed a statistically significant difference compared with standard values (p < 0.001 for all). However, their comparison with a severity level of the severe and non-severe groups showed significance for WBCs, neutrophils, NLR (p < 0.001 for all), and PLR (p = 0.06) only. Receiver operating characteristic curve analysis showed that NLR had the highest area under curve (0.84) followed by 1/lymphocyte (0.82), neutrophils (0.74), PLR (0.67),1/platelets (0.68) and WBC's (0.65). Comparison of cases and controls with recommended cut-off values derived from sensitivity and 1-specificity was also done (p < 0.001).Conclusion: Monitoring all the hematological and biochemical parameters including novel hemograms NLR, PLR can aid clinicians to identify potentially severe cases at early stages and initiate effective management in time which may reduce the overall mortality of COVID-19 patients.

Evaluation of hematological parameters as an indicator of disease severity in Covid-19 patients: Pakistan's experience.

BACKGROUND: The severity of COVID-19 could be evaluated by examining several blood parameters mainly white blood cell (WBC) count, granulocytes, platelet, and novel hemocytometric markers neutrophils to lymphocyte ratio (NLR), platelet-to-lymphocyte (PLR), and lymphocyte to monocyte ratio (LMR). The current study was conducted to investigate alteration in blood parameters and their association with the severity and mortality of COVID-19 patients. METHODOLOGY: An observational cross-sectional study was conducted retrospectively, a total of 101 COVID-19 positive patients were examined: 52 were mild, 24 were moderate, 09 were severe, and 16 were critically diseased patients. We also recorded 16 deaths associated with the critical group. The overall mean age observed in our study was 48.94 years, where the mean age for critical individuals was 62.12 ± 14.35 years. RESULTS: A significant association between the disease severity and elevation in blood parameters were observed. The WBC's and granulocyte count were significantly increased (p value <0.001) while the mean platelet count (165.0 × 109 /L) and red blood cell volume distribution width (RDW) were decreased in the critical group (57.86%) compared to mild group's patients (177.3%) (p = 0.83). The lymphocytes count was decreased in critical patients (1.40 × 109 /L) compared to mild patients (1.92 × 109 /L) (p = 0.28). A significant association was observed in platelet-lymphocyte ratio (p < 0.001), Neutrophil-Lymphocyte ratio (p = <0.001), and Lymphocyte-Monocyte ratio (0.011). CONCLUSION: These blood parameters could be used as a suitable biomarker for the prognosis and severity of COVID-19. Evaluating novel hemograms NLR, PLR, and LMR can aid clinicians to identify potentially severe cases at early stages, initiate effective management in time, and conduct early triage which may reduce the overall mortality of COVID-19 patients.

Is COVID-19 Immune to Misinformation? A Brief Overview.

During the current COVID-19 pandemic, misinformation is a major challenge, raising several social and psychological concerns. This article highlights the prevailing misinformation as an outbreak containing hoaxes, myths, and rumours. In comparison to traditional media, online media platforms facilitate misinformation even more widely. To further affirm this ethical concern, the researchers cite relevant studies demonstrating the role of new media in misinformation and its potential consequences. Besides other significant psychosocial impacts, such as xenophobia, psychological distress, LGBT rights violation, gender-based violence, misinformation is undermining healthcare workers' psychological health and their efforts to mitigate the impact of COVID-19. In view of the adverse consequences of misinformation, this article addresses it as a massive ethical challenge during the current outbreak. Thus, the researchers make relevant suggestions to evaluate misinformation sources and mitigate the psychosocial impacts attributed to misinformation during crises. They include forming mental health teams comprising of psychologists, psychiatrists, and trained paramedical staff; rapid dissemination of authentic and updated COVID-19 situation reports regularly; establishing helpline services; and recognizing a broader range of personal needs. All health authorities should make clear that they are listening and responding to public concerns. Much effort is needed to counteract COVID-19 misinformation.

COVID-19 and its Challenges for the Healthcare System in Pakistan.

This article aims to highlight the healthcare issues raised by COVID-19 in Pakistan's scenario. Initially, Pakistan lacked "standard operating procedures," and the government had to ship testing kits from China and Japan. Moreover, due to violations of the lockdown and standard operating procedures (SOPs), the rapidly increasing number of cases created a burden on the healthcare system. More and more, this pandemic and its impact have grown. As vaccine development has not been successful yet, "herd immunity" can only be achieved if about three quarters of the population contract the virus-requiring immunocompromised citizens to be sacrificed for the sake of the country. Moreover, Pakistan has limited testing capacity, so most COVID-19 tests are missing their mark even as the virus spreads. The current scenario is also raising several concerns about the capacity of the government to tackle the prevailing healthcare crisis. In this regard, healthcare professionals suggest that the government must act responsibly to ensure better security provided to healthcare professionals. Identifying suspected cases, introducing personal protective equipment, and taking administrative measures to ensure that better security is provided to healthcare professionals are the needs of the hour to improve outcomes of COVID-19 patients. Testing, tracking, and lockdowns must be focused on areas where clusters are detected. The healthcare professionals must be given utmost protection before this pandemic could wreak havoc in terms of fatalities. Investing in the chronically underfunded healthcare system is needed, so that Pakistan can build capacity to fight the pandemic.
