ABSTRACT
Introduction: The Sunderban area of West Bengal is home to tribal and religious minorities inhabiting various islands. There is a high prevalence of thalassemia among poverty-stricken residents of this region living with meagre health care facilities. This work was planned to determine the proportion of four viral transfusion-transmitted infections (TTIs): HIV-1, HIV-2, hepatitis B virus (HBV) and hepatitis C virus (HCV) among thalassemia patients attending the sole rural medical college in the region. Materials and Methods: Thalassemia patients (n = 359, age ranging from 1 year to 60 years) attending the thalassemia clinic or being admitted to the indoor facilities for better management were included in the study. Only patients diagnosed with high-performance liquid chromatography (HPLC) and with classical clinical features were included in the study. Blood samples of these patients were tested for HIV as per NACO protocol. For HBV and HCV, samples were first tested serologically; reactive samples were collected and sent in the cold chain to a higher centre for nucleic acid amplification testing (NAAT) for qualitative and quantitative estimation. Clinical and laboratory data was collected, patients were followed up for complications and hospitalisation during the study period, and statistical analysis was performed. Results: Majority of our patients had E-beta-thalassemia (245, 59.81%), followed by beta-thalassemia major (102, 28.30%). NAAT-confirmed HCV infection (14.21%) infection was the most common, followed by HBV (2.51%), and lastly by HIV-1 (0.58%) infection. Among infected thalassemia patients, the mean HCV RNA was 741063 ± 438514.67 IU/ml while the mean HBV DNA level was 4082863 ± 7298514 IU/ml. Co-infections of HIV-1 and HCV and that of HBV and HCV were noted in one patient each (0.28%). HCV-related liver disease (14.21%) and growth retardation (10.31%) were the most typical complication noted, and death occurred in five patients (1.39%) during the study period. Conclusion: Primary care physicians should know HCV infection is the most common TTI among thalassemia patients in rural eastern India.
ABSTRACT
Introduction: During the 2 years and 9 months from March 2020 to December 2022, the SARS-CoV-2 virus raged across the country. Cases occurred in three particular time clusters recognised by World Health Organisation as coronavirus disease 2019 (COVID-19) waves. In this study, we compare the clinical parameters of adult non-obstetric COVID-19 patients admitted to our rural tertiary care hospital during the three distinct waves of the pandemic. Materials and Methods: Retrospective chart analysis of 272, 853 and 97 patients admitted with SARS-CoV-2 infection to the only rural medical tertiary care centre in the Sunderbans of West Bengal in the first, second and third waves, respectively, was done after obtaining ethical and scientific clearance. Clinical [vital parameters, oxygen requirement, mental status, risk factor assessment, duration of hospital stay, modified-emergency warning score (m-EWS), quick Sequential Organ Failure Assessment (qSOFA), confusion, uraemia, respiratory rate, blood pressure, age ≥ 65 years (CURB65)], epidemiological variables (age, gender, and vaccination status), laboratory parameters and in-hospital outcome were recorded and analysed statistically. Results: Statistically significant (P < 0.05) m-EWS and qSOFA scores were recorded during the second wave of the pandemic. The second wave also recorded the highest mortality (14.89%) compared to the first (12.87%) and third (11.96%) waves, though this was not statistically significant. The highest duration of hospital stay was recorded in the first wave of the pandemic (mean = 9.99 days, P < 0.01). The difference in mortality rates between patients with and without co-morbidity (P < 0.05) was observed during Wave-1, across any pandemic wave, and overall but not in Wave-2 and Wave-3. Conclusion: The second wave of the COVID-19 pandemic was the most severe in comparison with the other two waves, while the outcome was poorer in those with co-morbidities, especially in the first wave.
