Persistence of SARS-CoV-2 in COVID-19 patients during the second wave of the pandemic in India.

INTRODUCTION: India witnessed the catastrophic second wave of COVID-19 during the summer months of 2021. Many patients with non-resolution of symptoms admitted to dedicated COVID-19 treatment centers required prolonged inpatient care which led to the unavailability of beds for other COVID-19 patients. The objective of this study was to determine the duration of SARS-CoV-2 positivity in moderate and severe COVID-19 patients requiring long-term pulmonary care as well as to find out the association between different variables with the persistence of the virus. METHODOLOGY: A retrospective chart review of clinical and laboratory data of patients with moderate and severe COVID-19 between 1st April 2021 and 15th July 2021 admitted for more than 28 days and requiring long-term pulmonary care was carried out at National Cancer Institute, AIIMS, India. SARS-CoV-2 RNA was detected with real-time reverse transcriptase-polymerase chain reaction-based tests. Data from all consecutively included patients satisfying the selection criteria were presented temporally and analyzed by Fisher's exact test (p < 0.05). RESULTS: All 51 patients tested positive for SARS-CoV-2 RNA at the 5th week of initial laboratory confirmation of COVID-19. The majority of the patients (38; 74.5%) remained positive for viral RNA till the 6th week and the median duration of viral positivity was 45 days. The clinical presentation of SARI at admission was significantly higher among patients with viral persistence till the 6th week (p < 0.05). CONCLUSIONS: The median duration of the viral positivity was 45 days and SARI at admission was significantly associated with viral persistence till the 6th week.

Clostridium septicum arthritis in a young infant: A case report.

Septic arthritis is one of the most serious conditions leading to grave consequences in all age groups, with a number of cases seen in infancy and childhood. Although septic arthritis in neonates is a known clinical entity, it is a diagnostic dilemma for the paediatricians. Of the reported causes of bacterial arthritis, anaerobic bacteria account for only 1%. Anaerobic bacterial septic arthritis may be more common than appreciated and therefore anaerobic as well as aerobic cultures should be done in all cases of septic arthritis. We report the first documented case of spontaneous septic arthritis due to Clostridium septicum in an infant with successful outcome.

Antimicrobial resistance profile of Methicillin-resistant Staphylococcus aureus colonizing the anterior nares of health-care workers and outpatients attending the remotely located tertiary care hospital of North India.

INTRODUCTION: Resistance to antimicrobial agents is a major concern worldwide and is exemplified by the global spread of the Methicillin resistant Staphylococcus aureus (MRSA). Health care workers (HCWs) and asymptomatically colonized patients are important sources of nosocomial MRSA infections. AIMS AND OBJECTIVES: To determine the prevalence of MRSA colonisation, two hundred HCWs and 200 consecutive outpatients attending our tertiary care hospital were studied. MATERIAL AND METHODS: Two sterile pre-moistened cotton tipped swabs were used to collect specimens from their anterior nares. These were inoculated immediately on Blood agar with oxacillin, Mannitol salt agar with oxacillin and CHROM agar. Resistance to cefoxitin was confirmed by PCR by demonstration of mecA gene. Antibiotic susceptibility was determined by Kirby Bauer's disc diffusion method and MIC of vancomycin by using broth dilution and Vitek-2 Compact system. RESULTS: The nasal carriage of MRSA among HCWs was found to be 7.5% and in outpatients 3%. All strains of MRSA from HCWs and outpatients grew on three selective media and mecA gene amplified in all of them. All the isolated strains of MRSA showed high degree of resistance to co-trimoxazole (93.3%), ciprofloxacin (80%) and erythromycin (66.66%). However, there was 100% susceptiability to vancomycin, teicoplanin, linezolid and Rifampicin. CONCLUSION: Although a direct casual relationship could not be established, it could be assumed that the transmission from colonised health care worker is responsible atleast in part for MRSA infection among patients. Therefore emphasis should be laid on strict implementation of standard infection control practices which would help in minimizing the carriage and transmission of MRSA in the hospital.

Hepatitis B virus and hepatitis C virus co-infection in hemodialysis patients: A retrospective study from a tertiary care hospital of North India.

BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections represent significant public health issues globally. They are important causes of morbidity and mortality in hemodialysis patients. Patients with HBV/HCV co-infection have a higher risk of progression to cirrhosis and decompensated liver disease and have an increased risk of hepatocellular cancer (HCC). Because the two hepatotropic viruses share same modes of transmission, co-infection with the two viruses is not uncommon, especially in areas with a high prevalence of HCV infection and among people at high-risk for parenteral infection. AIMS: To estimate the prevalence of HBV and HCV co-infection among hemodialysis patients. MATERIALS AND METHODS: This retrospective, single centered hospital record-based study was carried out in a tertiary care hospital in Faridkot (Punjab), India. All the patients who underwent hemodialysis from January 2013 to December 2014 were included in the study. Patients of all age groups were tested for anti-HCV antibodies by fourth Generation HCV Tridot ELISA (J. Mitra & Co. Pvt. Ltd., New Delhi, India) and for hepatitis B surface antigen (HBsAg) by Hepalisa (J. Mitra & Co. Pvt. Ltd). RESULTS: Of the total 262 patients on hemodialysis, 88 (33.5%) were found to be having HCV infection, 4 (1.5%) were found to be positive for HBsAg. Co-infection with HBV/HCV was observed in 2 (0.8%) patients. Out of the total 92 patients having HBV and HCV infection, 62 (67.4%) were males and 30 (32.6%) were females. The majority of the patients were found to be of 41-60 years of age (41.3%) followed by 21-40 years (31.5%) and thereafter in 61-80 years (23.9%) and lowest prevalence was observed in the age group of <20 years (2.2%) and >80 years (1.1%). CONCLUSION: The risk of co-infection is greater among the chronic renal failure (CRF) patients due to the high frequency of transfusions of blood/blood products and extracorporeal circulation during hemodialysis. Patients with HBV/HCV co-infection have a higher risk of progression to cirrhosis and decompensated liver disease and further have an increased risk of HCC. In our study, out of the total 262 patients, 88 (33.5%) were found to be having HCV infection, 4 (1.5%) were found to be positive for HBsAg and dual infection was observed in 2 (0.8%) patients which is higher than the rates reported from different studies all over the world and India.

Hepatitis C Virus (HCV) Infection among Seronegative Patients undergoing Haemodialysis in a Remotely Located Tertiary Care Hospital of Northern India: Value of HCV-RNA and Genotypes.

BACKGROUND: Haemodialysis (HD) patients are at an increased risk of Hepatitis C virus (HCV) infection, which is significantly associated with increased morbidity and mortality. AIM: The aim of this study was to find the prevalence of HCV infection in anti-HCV antibody negative haemodialysis patients by Real-time PCR (RT-PCR) and value of HCV-RNA among seronegative patients undergoing haemodialysis in a remotely located tertiary care hospital. MATERIALS AND METHODS: A total of 100 chronic renal failure patients on haemodialysis were studied. All the patients were screened for anti-HCV antibodies by ELISA test and for HCV-RNA by RT-PCR. RESULTS: The overall prevalence of HCV infection was 32%. Antibody positivity was 30% and HCV-RNA by RT-PCR was detected in 20%. HCV-RNA in seronegative patients was detected in 2.8%. CONCLUSION: Serological assays (30%) are quite reliable for detecting HCV infection in patients undergoing haemodialysis in our tertiary care hospital. Only a small proportion of them (2.8%) require the documentation of viral genome for current infection.
