Satellite Epidemic of Covid-19 Associated Mucormycosis in India: A Multi-Site Observational Study.

BACKGROUND: Sudden upsurge in cases of COVID-19 Associated Mucormycosis (CAM) following the second wave of the COVID-19 pandemic was recorded in India. This study describes the clinical characteristics, management and outcomes of CAM cases, and factors associated with mortality. METHODS: Microbiologically confirmed CAM cases were enrolled from April 2021 to September 2021 from ten diverse geographical locations in India. Data were collected using a structured questionnaire and entered into a web portal designed specifically for this investigation. Bivariate analyses and logistic regression were conducted using R version 4.0.2. RESULTS: A total of 336 CAM patients were enrolled; the majority were male (n = 232, 69.1%), literate (n = 261, 77.7%), and employed (n = 224, 66.7%). The commonest presenting symptoms in our cohort of patients were oro-facial and ophthalmological in nature. The median (Interquartile Range; IQR) interval between COVID diagnosis and admission due to mucormycosis was 31 (18, 47) days, whereas the median duration of symptoms of CAM before hospitalization was 10 (5, 20) days. All CAM cases received antifungal treatment, and debridement (either surgical or endoscopic or both) was carried out in the majority of them (326, 97.02%). Twenty-three (6.9%) of the enrolled CAM cases expired. The odds of death in CAM patients increased with an increase in HbA1c level (aOR: 1.34, 95%CI: 1.05, 1.72) following adjustment for age, gender, education and employment status. CONCLUSION: A longer vigil of around 4-6 weeks post-COVID-19 diagnosis is suggested for earlier diagnosis of CAM. Better glycemic control may avert mortality in admitted CAM cases.

A case control investigation of COVID-19 associated mucormycosis in India.

BACKGROUND: Increased occurrence of mucormycosis during the second wave of COVID-19 pandemic in early 2021 in India prompted us to undertake a multi-site case-control investigation. The objectives were to examine the monthly trend of COVID-19 Associated Mucormycosis (CAM) cases among in-patients and to identify factors associated with development of CAM. METHODS: Eleven study sites were involved across India; archived records since 1st January 2021 till 30th September 2021 were used for trend analysis. The cases and controls were enrolled during 15th June 2021 to 30th September 2021. Data were collected using a semi-structured questionnaire. Among 1211 enrolled participants, 336 were CAM cases and 875 were COVID-19 positive non-mucormycosis controls. RESULTS: CAM-case admissions reached their peak in May 2021 like a satellite epidemic after a month of in-patient admission peak recorded due to COVID-19. The odds of developing CAM increased with the history of working in a dusty environment (adjusted odds ratio; aOR 3.24, 95% CI 1.34, 7.82), diabetes mellitus (aOR: 31.83, 95% CI 13.96, 72.63), longer duration of hospital stay (aOR: 1.06, 95% CI 1.02, 1.11) and use of methylprednisolone (aOR: 2.71, 95% CI 1.37, 5.37) following adjustment for age, gender, occupation, education, type of houses used for living, requirement of ventilatory support and route of steroid administration. Higher proportion of CAM cases required supplemental oxygen compared to the controls; use of non-rebreather mask (NRBM) was associated as a protective factor against mucormycosis compared to face masks (aOR: 0.18, 95% CI 0.08, 0.41). Genomic sequencing of archived respiratory samples revealed similar occurrences of Delta and Delta derivates of SARS-CoV-2 infection in both cases and controls. CONCLUSIONS: Appropriate management of hyperglycemia, judicious use of steroids and use of NRBM during oxygen supplementation among COVID-19 patients have the potential to reduce the risk of occurrence of mucormycosis. Avoiding exposure to dusty environment would add to such prevention efforts.

Unusual clinical presentations of scrub typhus, a neglected tropical disease: A case series from north India.

BACKGROUND & OBJECTIVES: Scrub typhus is a neglected tropical disease common in Asia and Africa. It usually presents with non-specific symptoms like fever, rashes, and lymphadenopathy. It has a varying range of clinical picture that often leads to misdiagnosis and initiation of non-specific treatment. This disease is thus associated with high morbidity and mortality. We aim to highlight the uncommon presentations of this common disease to create awareness regarding the unusual presentations of scrub typhus. METHODS: This prospective study was performed over a period of two months enrolling eleven adult patients with serological evidence of anti-scrub typhus IgM antibodies. RESULTS: All enrolled 11 cases [5 males (45.5%) and 6 females (54.5%)] were positive for anti-ST IgM antibodies and negative for other tested microbial agents. 7/11 (63.6%) patients were admitted with a clinical diagnosis of acute encephalitis syndrome (AES as per standard WHO definition), 3/11 (27.3%) patients presented with jaundice and 1/11 (9.1%) patients presented with rashes. Two out of 7 (28.6%) AES cases had developed peripheral gangrene of extremities. INTERPRETATION & CONCLUSION: Scrub typhus is a common tropical disease that can have various unusual clinical presentations like meningoencephalitis, vasculitis, acute kidney injury, jaundice, MODS. It closely mimics other infective etiologies making its diagnosis difficult. A high index of suspicion and clinical awareness is required in clinical practice to identify the different presentations of this disease so that early treatment can be initiated to reduce morbidity and mortality associated with this disease.

Thrombocytopenia as a Prognostic Marker in Patients with Acute Encephalitis at a Tertiary Care Centre in Northern India.

Encephalitis is challenging to manage given the diversity of clinical and epidemiologic features. Various predictors of outcome have been studied so far including thrombocytopenia, cerebral edema, hypoglycaemia, development of status epilepticus and need for endotracheal intubation. Thrombocytopenia represents one of the potentially modifiable risk factors for poor prognosis in encephalitis. A better understanding of the epidemiology of this devastating disease and identification of predictors of outcome and management of reversible factors will pave the way for better management of the disease. MATERIAL: A total of 98 Hospitalised patients of Acute Encephalitis were enrolled in the study. Diagnoses were confirmed by CSF and Neuroimaging studies. Platelet count <150,000/cumm was considered as thrombocytopenia. Mild, moderate and severe thrombocytopenia was categorized at platelet count 100,000-150,000, 50,000-100,000 and <50,000/ cumm, respectively. Outcome at discharge was assessed using the Modified Ranking Score, categorized into 3 groups - good (0-2), fair (3-4), and poor (5-6). Chi-square, ANOVA and Independent samples 't'-tests were used to compare the data. OBSERVATION: Mean age of patients was 34.06±18.76 (range 14-85) years. Majority of patients were males (54.1). Mean GCS at admission was 9.41±1.90. Acute viral encephalitis(unclassified) (n=33; 33.7%), Scrub typhus (n=24; 24.5%) and Japanese encephalitis virus (n=12; 12.2%) were the most common underlying etiologies. A total of 74 (75.5%) patients had thrombocytopenia. Mild, moderate and severe thrombocytopenia was seen in 34 (34.7%), 30 (30.6%) and 10 (10.2%) cases. Thrombocytopenia was significantly higher in Dengue and Scrub as compared to other etiologies. Thrombocytopenia and its severity showed a significant association with lower GCS and higher mRS scores indicating a poor outcome. CONCLUSION: Thrombocytopenia is associated with a poor clinical status and adverse outcomes in patients with encephalitis of all causes.

Ambulatory Blood Pressure Monitoring in Chronic Obstructive Pulmonary Disease Patients.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is now considered as multisystem disorder with high cardiovascular mortality. The study was carried out with an objective to observe the pattern and variation of blood pressure (BP) using ambulatory blood pressure monitoring (ABPM) in COPD patients. METHODS: Thirty six cases of COPD diagnosed by spirometry underwent ABPM for blood pressure evaluation. Thirty controls without COPD underwent spirometry and ABPM. Analysis were carried out both during wakefulness and sleep. RESULTS: Out of 36 COPD cases 25 were found to be hypertensive on ABPM, while 2 out of 30 controls were found to be hypertensive on ABPM. A significant difference was found between blood pressure levels during the wakefulness, sleep, and 24-hour BP amongst COPD cases and controls. Higher blood pressure levels were observed in COPD patients then in control, except for diastolic levels during wakefulness. The normal nocturnal dip was attenuated in COPD patients whereas physiological dip was present in controls. CONCLUSION: COPD patients had higher blood pressure levels than the control group and had abnormal dipping pattern of blood pressure which may lead to high cardiovascular mortality in patients of COPD.

Helicobacter pylori Reactivates Human Immunodeficiency Virus-1 in Latently Infected Monocytes with Increased Expression of IL-1ß and CXCL8.

BACKGROUND: Helicobacter pylori are gram-negative bacteria, which colonize the human stomach. More than 50% of the world's population is infected by H. pylori. Based on the high prevalence of H. pylori, it is very likely that HIV and H. pylori infection may coexist. However, the molecular events that occur during HIV-H. pylori co-infection remain unclear. Latent HIV reservoirs are the major obstacle in HIV cure despite effective therapy. Here, we explored the effect of H. pylori stimulation on latently HIV-infected monocytic cell line U1. METHODS: High throughput RNA-Seq using Illumina platform was performed to analyse the change in transcriptome between unstimulated and H. pylori-stimulated latently HIV-infected U1 cells. Transcriptome analysis identified potential genes and pathways involved in the reversal of HIV latency using bioinformatic tools that were validated by real-time PCR. RESULTS: H. pylori stimulation increased the expression of HIV-1 Gag, both at transcription (p<0.001) and protein level. H. pylori stimulation also increased the expression of proinflammatory cytokines IL-1ß, CXCL8 and CXCL10 (p<0.0001). Heat-killed H. pylori retained their ability to induce HIV transcription. RNA-Seq analysis revealed 197 significantly upregulated and 101 significantly downregulated genes in H. pylori-stimulated U1 cells. IL-1ß and CXCL8 were found to be significantly upregulated using transcriptome analysis, which was consistent with real-time PCR data. CONCLUSION: H. pylori reactivate HIV-1 in latently infected monocytes with the upregulation of IL-1ß and CXCL8, which are prominent cytokines involved in the majority of inflammatory pathways. Our results warrant future in vivo studies elucidating the effect of H. pylori in HIV latency and pathogenesis.

Status of adult immunity to hepatitis A virus in healthcare workers from a tertiary care hospital in north India.

Background & objectives: Humans are considered to be the principal host for hepatitis A virus (HAV) infection. In India, heterogeneous groups of susceptible individuals coexist in different regions. There has been a decline in antibody titres to HAV among young adults which may pose a major public health problem. The objective of this study was to assess the IgG anti-HAV level among healthcare workers (HCWs) in the age group of 20-60 yr and its association with the socio-demographic variables. Methods: Blood sample (2 ml) was collected under aseptic conditions from each participant followed by the preparation of serum and storing at -20°C. ELISA-based kits were used for the determination of IgG antibodies to HAV in the human serum samples. Results: Two hundred and fifty four HCWs were enrolled. IgG anti-HAV antibodies were detected in 97.2 per cent of the samples analyzed. No differences were observed in the levels of IgG anti-HAV antibody and education, income, occupation and socio-economic classes of the HCWs. A seropositivity rate of over 90 per cent was seen amongst all the socio-economic classes. Interpretation & conclusions: High levels of IgG protective antibodies were seen among the studied HCWs, hence HAV vaccination may not be required. It will be advisable to do a cost-benefit analysis of vaccination for HAV.

Study of Pulmonary Function Test Abnormalities in Metabolic Syndrome.

INTRODUCTION: Metabolic Syndrome (MetS) is defined as a constellation of an interconnected physiological, biochemical, clinical, and metabolic factors that directly increases the risk of atherosclerotic cardiovascular disease and T2DM. Although the link between impaired lung function and cardiovascular events and T2DM has been recognized, the association between impaired lung function and MetS has not been comprehensively assessed. MATERIAL AND METHODS: A cross sectional prevalence study was done in tertiary care hospital in northern India on 100 patients of the age between 25-65 years who fulfilled the IDF criteria for MetS to evaluate pulmonary function test (Spirometry) abnormalities. RESULTS: Maximum number of patients were in 31-40 years of age group (45%) followed by those aged 41-50 year (26%), < 30 years (15%), >50 years (14%). Mean age of patients was 39.59±8.67 year. In this cross-sectional study, patients with Metabolic Syndrome showed significantly lower FVC % predicted (P< 0.001), FEV1 % predicted (P< 0.001) as compared to the group without Metabolic Syndrome. There was a strong linear decrease in FVC and FEV1 % predicted as the number of components of MetS increases. We observed that 28% of the male and 46.6% of female patients showed restrictive ventilatory pattern and 7% of male and 13.4% of female patients showed mixed pattern. CONCLUSION: All MetS components were associated with pulmonary function impairment. As the number of MetS components increases, patients had more severe decline in pulmonary functions.

Crestal Bone Loss under Delayed Loading of Full Thickness Versus Flapless Surgically Placed Dental Implants in Controlled Type 2 Diabetic Patients: A Parallel Group Randomized Clinical Trial.

PURPOSE: To compare crestal bone loss around dental implants using a delayed loading protocol. Bone loss was compared in patients following conventional full thickness flap and flapless surgery in controlled type 2 diabetic patients. MATERIALS AND METHODS: Eighty-eight type 2 diabetic patients satisfying predetermined inclusion and exclusion criteria were selected for this single center, parallel group study after obtaining institutional review board approval and informed consent. These patients were randomly divided into two groups. Group I consisted of patients undergoing full thickness flap surgery for implant placement, and group II consisted of patients undergoing flapless surgery for implant placement. The mean age, duration of diabetes, glycosylated hemoglobin levels, and male-to-female ratio in both groups were matched and compared statistically. Dental implants were placed followed by delayed loading (4 months) in both groups. Crestal bone loss was assessed with intraoral periapical radiographs with the help of computer software (DBSWIN viewer). Actual implant length acted as the radiographic index, and implant-abutment junctions were used as a reference point for all measurements. Mesial and distal bone levels at baseline, 6, and 12 months post implant placement of the two groups were determined. Mesial and distal crestal bone loss from baseline to 6 and 12 months were calculated and compared with Tukey test using SPSS v15.0 statistical analysis software. RESULTS: Tukey test revealed similar (not statistically different) mean mesial crestal bone loss between the two groups after 6 months (0.47 ± 0.08 mm vs. 0.36 ± 0.13 mm, p = 0.576) and after 12 months (1.56 ± 0.25 mm vs. 1.50 ± 0.22 mm, p = 0.891). The mean distal bone loss resulting between the two groups was not statistically different at 6 months (0.44 ± 0.08 mm vs. 0.35 ± 0.12 mm, p = 0.687) and at 12 months (1.57 ± 0.23 mm vs. 1.61 ± 0.22 mm, p = 0.947). CONCLUSIONS: The results of this clinical randomized control trial indicated that in controlled type 2 diabetic patients, levels of crestal bone loss around dental implants placed following conventional full thickness flap surgery was comparable to crestal bone loss around dental implants placed with the flapless surgical technique. More clinical studies are required regarding controlled type 2 diabetics with larger sample sizes, for long time periods to obtain more predictable results.

Awareness and Outcome of Changing Trends in Clinical Profile of Dengue Fever: A Retrospective Analysis of Dengue Epidemic from January to December 2014 at a Tertiary Care Hospital.

BACKGROUND: Dengue fever is caused by mosquito-borne arboviral infection that has become a public health concern globally. Recently, an alarming rise of dengue has also been seen in India. Hence the study was undertaken to know profile of clinical manifestations and laboratory findings during the evolution of dengue fever. METHODS: In this study, retrospective data analysis was done in 216 seropositive dengue patients admitted between January to December 2014 in department of medicine at a north Indian care hospital. The tests analyzed were blood counts, serum electrolytes, liver function tests, kidney function tests, chest x-ray and other relevant investigations. RESULTS: Males were commonly affected and the most exposed age group was found to be18-35 years. The seropositive case rate for dengue was 56% for NS1 antigen and 36% for IgM. There was rural dominancy of cases with a peak in September. Fever was the most common clinical feature followed by headache, myalgia, backache, nausea and abdominal pain. Petechia was most common haemorrhagic manifestation. Common laboratory findings included 89.35% decreased Platelet counts (<100 000/cmm), 67.59% increased hematocrit (>45%) and 58.33% deranged liver function test. There was no reported mortality in dengue. CONCLUSIONS: From prompt and proper treatment could prevent deaths in moderate and severe dengue. Atypical presentations of dengue should be kept in mind so as not to miss the cases. Increased community awareness and vector control measures need to be strengthened during peri-monsoon period to reduce burden of dengue cases.

Uttar Pradesh Association of Physicians of India Position Statement: Tobacco Use and Metabolic Syndrome.

Tobacco use is one of the main preventable causes of mortality and morbidity worldwide. The global disease burden due to tobacco use is huge with projected mortality of eight million lives per year by 2030. Metabolic syndrome (MS) is defined as a constellation of cardiovascular and endocrine risk factors such as insulin resistance, obesity, raised blood pressure, and abnormal lipid profile. The relationship between tobacco use and MS has been well established. Also, the causal association between tobacco use and development of individual components of MS is well established. The Uttar Pradesh Association of Physicians of India (UP API) has drafted this position statement on managing tobacco use among persons with or at risk of developing Metabolic Syndrome (MS). This position statement presents evidence-based recommendations as described below. Scope and purpose The objective of this position statement is to offer clinical recommendations for screening, diagnosis and management of tobacco use among persons with or at risk of developing Metabolic Syndrome (MS). The purpose of this document is to aid in identification and treatment of maladaptive patterns of tobacco use i.e. tobacco use disorder (tobacco dependence, harmful use, abuse) in person with or at risk of developing MS. Intended Audience The position statement is targeted at the clinicians engaged in care and management of person with or at risk of developing Metabolic Syndrome (MS). This might also be of relevance to the policy makers considering the public health burden of both MS and tobacco use disorders.

Conservative Surgical Management of a Pulmonary Hydatid Cyst in an Adolescent Having Extra-pulmonary Lesions by a Multi-disciplinary Approach.

Echinococcus granulosus causes hydatid cysts, a significant zoonotic and pulmonary parasitic disease that can mimic various pathologies and is often harder to manage than the disease itself. A hydatid cyst is considered a significant health problem in India, Iran, China, and Mediterranean countries, which lack satisfactory environmental health, preventive medicine, and veterinarian services. Echinococcosis continues to be a major community health burden in several countries, and in some terrains, it constitutes an emerging and re-emerging disease. Cystic echinococcosis is the most common human disease of this genus, and it accounts for a significant number of cases worldwide. Herein, a case involving an 11-year-old presenting with fever, dry cough, and right hypochondrial pain is presented, where imaging revealed a hydatid cyst in the lung. Surgical removal of the cyst was achieved through right posterolateral thoracotomy under one-lung ventilation and anesthesia using intubation with a double-lumen endotracheal tube (DLET or DLT), highlighting surgery as the primary treatment despite the lack of consensus on surgical methods. This case underscores the effectiveness of individualized, parenchyma-preserving surgery for even large, uncomplicated cysts, indicating a positive prognosis.

Acute Liver Failure Prognostic Criteria: It's Time to Revisit.

INTRODUCTION: Acute liver failure (ALF) is a devastating disease, and patients are at a higher risk of death without liver transplantation. Indicators are needed to identify the risk of death in ALF, which will help in the timely referral of patients to specialized centers. Clichy criteriaand King's College Hospital (KCH) criteria are the most widely used prognostic criteria. Real-life application of Clichy criteria is limited due to the non-availability of factor V level measurement. KCH criteria have good specificity but low sensitivity to predict outcomes. Therefore, we attempted to use the model for end-stage liver disease (MELD) score and chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score in ALF patients as prognostic indicators and need for liver transplantation. METHODS: Forty-one patients with ALF were enrolled in the study. On the day of admission, MELD and CLIF-SOFA scores were calculated for each patient. Area under receiver operating characteristics (AUROC) curve, sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and diagnostic accuracy (DA) of MELD and CLIF-SOFA score were calculated to predict the outcome of the patients. RESULTS: Out of 41 patients, nine patients left against medical advice. The sensitivity, specificity, PPV, NPV, and DA for the MELD score of enrolled patients in the study were 81.5%, 62.5%, 59.5%, 83.3%, 70.1%, and for the CLIF-SOFA score of enrolled patients in the study were 88.9%, 90.0%, 85.7%, 92.3%, 89.6% respectively. Patients who did not survive had higher INR, MELD, CLIF-SOFA scores, and hepatic encephalopathy (HE) grades. Five patients who had a combination of MELD ≥30 and CLIF-SOFA ≥10, expired. CONCLUSION:  In our study, we used MELD score and CLIF-SOFA as prognostic markers, and we concluded that CLIF-SOFA is a better predictor of mortality than MELD score in terms of sensitivity, specificity, NPV, PPV, and diagnostic accuracy. AUROC for CLIF-SOFA score is higher when compared to the MELD score.

Obstructive Sleep Apnea in Hypertension.

Introduction About one-half of patients who have essential hypertension have obstructive sleep apnea (OSA), and about one-half of patients who have obstructive sleep apnea have essential hypertension. OSA can cause even resistant hypertension if left untreated. These two entities often co-exist and are seen as a continuum of the same process. Eighty percent to 90% of OSA cases are undiagnosed mostly because of a lack of awareness. Material and methods This was a cross-sectional study done over a period of one year in a tertiary care hospital. After taking informed consent, 179 hypertensive patients of >18 years were included in the study. All patients were screened for OSA by the STOP-BANG questionnaire. Patients having scores of ≥3 were subjected to overnight polysomnography to confirm the diagnosis of OSA (AHI ≥5). Patients with a STOP-BANG score ≤2 or score ≥3 with AHI <5, were considered non-OSA. Results More than half (53.1%) of the patients enrolled in the study had OSA. Their age ranged from 18 to 78 years and the mean age was 52.07±11.40 years. The mean age of OSA cases was found to be slightly higher than that of non-OSA. The majority of OSA cases were males (73.7%). There was an increase in the prevalence, as well as the severity of OSA, with an increase in BMI. Most of the cases had snoring and a history of tiredness. Triglyceride (TG) and low-density lipoprotein (LDL) levels of the OSA group were found to be significantly higher and high-density lipoprotein (HDL) levels were significantly lower than that of the non-OSA group. Conclusion More than half of our hypertensive patients had OSA. These two conditions often co-exist and are known as a dangerous pair. Physicians ought to have increased suspicion for early diagnosis and treatment to improve cardiovascular outcomes, reduce road traffic accidents, and improve quality of life.
