Determinants of Poison-related Mortality in Tertiary Care Hospital, South India.

Aims and background: Acute poisoning is one of the most common emergencies in India and around the world. Understanding the factors associated with mortality can aid us in devising appropriate preventive strategies to curtail deaths due to poisoning. Purpose of this study is to find various factors that determine the mortality among acute poisoning cases admitted in a tertiary care center. Materials and methods: A retrospective hospital records-based study was conducted at Chengalpattu Medical College Hospital. The study included 2,123 cases of various poisoning cases admitted for a year from January to December 2022. Cases of bites, stings, drowning, and hanging were excluded. Information on sociodemographic profile, type of poison, time since ingestion and admission, and treatment outcome were collected using a structured pro forma. Results: The mean age of the study population was 29.90 ± 14.98 years. Poisoning was found to be predominantly among males (56.42%) and residents of rural areas (58%). Insecticide consumption (27.0%) was the most common modality, followed by oleander poisoning (20%), corrosive poison (17%), rat poison (15%), tablet poison (13%), and other poisons. The overall case fatality rate (CFR) was 5.2%, with the highest CFR of 12.25% with insecticide poisoning. In multivariate analysis, Glasgow coma scale (GCS) score at admission is the only parameter showing a statistically significant association with mortality (adjusted odds-ratio 0.271(0.2-0.38, p-value < 0.01). Conclusion: Acute poisoning primarily affects the young and economically productive population. In the south Indian population, pesticides are still the major contributor though corrosives are a major contributor among children. Mortality is still significant, and GCS status admission is the only predictor of mortality.

Convalescent plasma transfusion for the treatment of COVID-19: Systematic review.

The recent emergence of coronavirus disease 2019 (COVID-19) pandemic has reassessed the usefulness of historic convalescent plasma transfusion (CPT). This review was conducted to evaluate the effectiveness of CPT therapy in COVID-19 patients based on the publications reported till date. To our knowledge, this is the first systematic review on convalescent plasma on clinically relevant outcomes in individuals with COVID-19. PubMed, EMBASE, and Medline databases were searched upto 19 April 2020. All records were screened as per the protocol eligibility criteria. We included five studies reporting CPT to COVID-19 patients. The main findings from available data are as follows: (a) Convalescent plasma may reduce mortality in critically ill patients, (b) Increase in neutralizing antibody titers and disappearance of SARS-CoV-2 RNA was observed in almost all the patients after CPT therapy, and (c) Beneficial effect on clinical symptoms after administration of convalescent plasma. Based on the limited scientific data, CPT therapy in COVID-19 patients appears safe, clinically effective, and reduces mortality. Well-designed large multicenter clinical trial studies should be conducted urgently to establish the efficacy of CPT to COVID-19 patients.

Analysis of blood lead level and its clinical significance among occupational exposed painters in chennai based population: A cross sectional study.

INTRODUCTION AND AIM: Lead is a ubiquitous element found in the earth crust. There is no known physiologic role of lead in human body and hence any amount of lead present in human tissue considered as a contamination. Several studies on lead toxicity show that, occupational exposure remains the main source for lead toxicity and is emerging as important public health problem. Burden and severity of occupational exposure of lead and its clinical significance are gaining more interest in the field of toxicology. Only limited studies are available and there is scarcity of epidemiology data to assess the blood lead levels of workers and the contribution of common workplace practices to lead exposure in India especially from our region. So, the current study is designed to assess the blood lead levels (BLL) and its clinical significance among high risk workers especially painters working in the construction and public private sector in Chennai based population. MATERIALS AND METHODS: This cross-sectional case control study included 122 painters and 122 healthy individuals. A detailed questionnaire about demographic details, personal habits, work related safety precautions, presenting symptoms of lead toxicity were given to painter followed by detailed medical examination and blood investigations including blood lead levels were collected and statistically analyzed. The t-test were used to compare mean blood lead levels and to investigate the associations between specific job type, use of self-protection device,sex, service years and occurrence of non-specific symptoms with BLLs. RESULTS: The mean BLL of the painters were less than the recommended threshold level. Among painters 13.1% were categorized under BLL > 10 µg/dL. The higher BLL among the painters were directly proportional to year of experience and poor usage of personal protective materials. The levels of Hb, HCT and eosinophil were much correlated with lead toxicity. A marginal significance were observed in some parameters especially urea and creatinine when compared with control. The Cognitive dysfunction, hypertension and renal dysfunction were also observed among the painters. CONCLUSION: The BLL in painters among our group were minimal compared to biological reference value. Duration of exposure and association of patient's clinical features like cognitive dysfunction, hypertension and renal dysfunction conditions were observed and this should be carefully monitored and study on huge population of painters with longitudinal aspect is recommended to rule out the clinical correlation of lead toxicity.

Elevated Liver Enzymes along with Comorbidity Is a High Risk Factor for COVID-19 Mortality: A South Indian Study on 1,512 Patients.

BACKGROUND AND AIMS: Liver enzyme abnormalities in coronavirus 2019 (COVID-19) are being addressed in the literature. The predictive risk of elevated liver enzymes has not been established for COVID-19 mortality. In this study, we hypothesized that elevated liver enzymes at admission can predict the outcome of COVID-19 disease with other known indicators, such as comorbidities. METHODS: This retrospective study included all the consecutive hospitalized patients with confirmed COVID-19 disease from March 4th to May 31st, 2020. The study was conducted in Rajiv Gandhi Government General Hospital, Chennai, Tamil Nadu, India. We assessed demography, clinical variables, COVID-19 severity, laboratory parameters, and outcome. RESULTS: We included 1,512 patients, and median age was 47 years (interquartile range: 34-60) with 36.9% being female. Liver enzyme level (aspartate aminotransferase and/or alanine aminotransferase) was elevated in 450/1,512 (29.76%) patients. Comorbidity was present in 713/1,512 (47.16%) patients. Patients with liver enzymes' elevation and presence of comorbidity were older, more frequently hospitalized in ICU and had more severe symptoms of COVID-19 at the time of admission. Presence of liver enzymes' elevation with comorbidity was a high risk factor for death (OR: 5.314, 95% CI: 2.278-12.393), as compared to patients with presence of comorbidity (OR: 4.096, 95% CI: 1.833-9.157). CONCLUSIONS: Comorbidity combined with liver enzymes' elevation at presentation independently increased the risk of death in COVID-19 by at least 5-fold.

In COVID-19 Patients, the Identified Gastrointestinal Symptoms in Tertiary Care Center of India.

Aim: This study aimed to assess the demographic details of coronavirus disease-2019 (COVID-19) patients, their comorbid conditions, preexisting illnesses such as tuberculosis (TB), the prevalence of gastrointestinal (GI) symptoms, duration of GI symptoms, gender-wise distribution of GI symptoms, age-wise distribution of GI symptoms, lab investigation, and computed tomography (CT) scanning was done to record the grading. Materials and methods: In total, 956 COVID-19 patients admitted to an isolation ward of a tertiary care center were screened for 3 months. Patients were confirmed positive for SARS-CoV-2 virus by real-time polymerase chain reaction (RT-PCR) test with a throat swab. Patient's age, demographic details, preexisting illness, and GI symptoms such as fever, impairment of appetite, loss of taste, loss of smell, hiccups, nausea, vomiting, diarrhea, abdominal pain, symptom's duration, history of chronic drug intake, biological markers, CT scanning, and comorbidities were recorded. Based on the provided protocol, standard care management was given to the admitted COVID-19 patients.Statistical analysis was performed using SPSS version 20.0. Frequencies with percentages, median (min, max), Chi-square test, and Mann-Whitney U test were used to test the statistical significance, and a p-value of <0.05 was considered statistically significant. Results: In our prospective study of 956 COVID-19 hospitalized patients, details were analyzed and the results are: the median age was 45 years, 70% of male, 60% were above 35 years, comorbidities like diabetes present in 42%, hypertension in 36%, asthma in 8%, cardiovascular diseases (CVD) in 5%, and history of chronic drug intake in 21%.Among 956 COVID-19 patients, GI symptoms were loss of smell (29.2%), loss of taste (26.4%) for 3 days; nausea (10%), vomiting (7.1%), abdominal pain (12.7%), and fever (42.5%) were observed for 2 days among the 36-45 years of age-group; and the loss of appetite (19%) for 3 days among the age-group of 46-55 years.The loss of appetite (23.7 vs 16.9%) (p= 0.014), taste (32.4 vs 23.8%) (p = 0.005), nausea (14.6 vs 8.2%) (p = 0.003), and vomiting (10.8 vs 5.5%) (p = 0.004) were higher in females than in males. No gender difference was observed in loss of smell (p = 0.057), abdominal pain (12 vs 14.3%) (p = 0.491), hiccups (4 vs 2.1%) (p = 0.132), and fever (41.3 vs 45.3%) (p = 0.329).Females had significantly higher levels of C-reactive protein (CRP) than males (6.1 vs 3.8) (p = 0.002). No gender difference was observed in neutrophil/lymphocyte ratio (NLR) (p = 0.772), ferritin, and lactate dehydrogenase (LDH). CT-grade IV was higher in males than in females (1.7 vs 1.5%), but the rest of the CT grades were higher in females than in males. Conclusion: In conclusion, GI symptoms are the onset of symptoms that are first expressed after being infected with the SARS-CoV-2 virus. Several studies showed the GI symptoms but did not analyze the age and gender that are risk factors for any disease, but our study showed all GI symptoms and their association with age and gender, which will shed light for our clinicians for early symptom identification, diagnosis, and appropriate treatment.

Clinical Outcomes among Asymptomatic or Mildly Symptomatic COVID-19 Patients in an Isolation Facility in Chennai, India.

Globally, India has reported the third highest number of COVID-19 cases. Chennai, the capital of Tamil Nadu state, witnessed a huge surge in COVID-19 cases, resulting in the establishment of isolation facilities named COVID Care Center (CCC). In our study, we describe the demographic, epidemiological, and clinical characteristics; clinical progression; and outcome of 1,263 asymptomatic/mildly symptomatic COVID-19 patients isolated in one such CCC between May 4, 2020 and June 4, 2020. Around 10.5% of the patients progressed to moderate/severe illness, requiring referral for tertiary care, and three died. Nearly half (49.5%) of the patients were symptomatic at the time of admission, 2.2% of the patients developed symptoms post-testing, and 48.5% patients remained asymptomatic during the entire course of illness. Most common presenting symptoms were fever (69.9%) and cough (29.6%), followed by generalized body pain, breathlessness, and loss of smell and taste. On multivariate analysis, we identified that symptomatic patients with comorbidities and higher neutrophil-lymphocyte ratio (NLR) were more likely to progress to severe illness warranting referral for tertiary care. COVID Care Center ensured case isolation and monitoring of asymptomatic/mildly symptomatic patients, thereby providing hospital beds for sick patients. COVID Care Center isolation facilities are safe alternatives for medical institutions to isolate and monitor COVID-19 patients. Older symptomatic patients with comorbidities and a high NLR admitted in an isolation facility must be frequently monitored for prompt identification of clinical progression and referral to higher center for advanced medical care.
