Dengue is a highly prevalent mosquito-borne disease that is endemic in over 100 countries. It has a wider impact in terms of severity of illness and mortality risk in the absence of an effective vaccine as yet. The purpose of this study was to use meta-analysis to find out how common the dengue virus (DENV) is in India based on public data and to figure out how much of a problem. We searched, read, and reviewed about DENV in India that were available online. Forty-four cross-sectional studies were selected from the 178 records. There were reports of dengue cases in 14 out of the 28 states. Out of the patients presenting with symptoms of Dengue 27% of people were confirmed to have DENV infection with 82.29% (95% CI. 81-84%), having dengue IgM, 41.67% (95% CI: 40.16-43.43), having dengue IgG, and 23.97% (95% C.I. 14-43%), having both IgG and IgM from positive sample n=27156. Hospital-based cross-sectional studies on suspected Dengue-like illness (DLI) found that 99.48% of people had confirmed dengue out of the patients with features of DLI, and community-based studies found that 0.52% of DLI cases had dengue. The seroprevalence rates for East, South, North, and Western regions were 35.38% (95% C.I.14-31%), 11.57% (95% C.I. 2-69%), 38.10% (95% C.I. 9-61%), and 14.87% (95% C.I. 6-38%) correspondingly. DENV is interestingly spreading across the whole country, and the disease’s frequency varies a lot from place to place and from 2010-2023. However this review does not find appropriate published literature from 50% of the Indian states. The identification of IgG-class antibodies to dengue virus is indicative of prior exposure to this pathogen. Almost all immunocompetent individuals should have developed IgG antibodies against the dengue virus within three weeks of exposure. The presence of dengue virus IgM-class antibodies is indicative of an acute phase of infection. National Vector borne Disease Control Programme (NVBDCP) has some surveillance information, appropriate designed research into prevalence and risk factors for DENV infection would be required to provide adequate information for public health intervention.

BackgroundMaternal malnutrition affects the somatic growth of the fetus and subsequent adverse events during infancy and childhood period. Though trials have been conducted on multiple micronutrient (MMN) supplements initiated during the preconception period, there is no collated evidence on this.Materials and methodsWe performed a systematic review of published trials with the application of Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The searches were conducted until 30 September 2023. Meta-analysis was performed using Review Manager 5 software. The primary objective was to compare the effect of preconception MMN vs. iron–folic acid (IFA) supplementation on newborn anthropometric parameters at birth.ResultsOf the 11,832 total citations retrieved, 12 studies with data from 11,391 participants [Intervention = 5,767; Control = 5,624] were included. For the primary outcome, there was no significant difference in the birth weight [MD, 35.61 (95% CI, −7.83 to 79.06), p = 0.11], birth length [MD, 0.19 (95% CI, −0.03 to 0.42), p = 0.09], and head circumference [MD, −0.25 (95% CI, −0.64 to −0.14), p = 0.22] between the MMN and control groups. For all the secondary outcomes [except for small for gestational age (SGA) and low birth weight (LBW)], the difference between the MMN and control groups was not significant. The GRADE evidence generated for all the outcomes varied from “very low to moderate certainty.”ConclusionA “very low certainty” of evidence suggests that MMN supplementation may not be better than routine IFA supplementation in improving newborn anthropometric parameters (weight, length, and head circumference). The adverse events resulting from the supplementation were not significant. We need better quality uniformly designed RCTs before any firm recommendation can be made.Systematic review registration: identifier (CRD42019144878: https://www.crd.york.ac.uk/prospero/#searchadvanced).

Background: Snakebite remains a significant public health problem worldwide, particularly in rural areas with unexpected morbidity and mortality. This study evaluated the clinical, laboratory profile and outcomes in children with snake bites from Eastern India. Methods: This was a retrospective case record-based study between January 2017 and December 2021. The clinical features, complications, laboratory profiles and outcomes were analysed. Results: Thirty children with snake bites were admitted during this study period. There was a male predominance with a ratio of 2.3:1. The mean age of presentation was 10.4 years. About 60% of bites occurred during the rainy season between July and September. Most bites (96%) were on lower limbs, predominantly showing vasculotoxic features followed by neurotoxic and a combined presentation. In this study, around 53% received anti-snake venom (ASV) before reaching our centre; the median time to reach our centre was 13 h. Complications such as acute kidney injury (AKI), cellulitis, shock and coagulation abnormalities were common in those who arrived early (before 6 h) than in those who reached late (after 6 h). Similarly, the mean duration of hospital stay was less for those seeking medical attention early as compared to those reaching late for treatment (4.7 days vs. 7.2 days). Twenty-six out of 30 (86.7%) were discharged without any sequelae, 3 (10%) children were left against medical advice and one died. Conclusions: Snakebite remains a major health problem in children causing significant morbidity and mortality. Children, in general, especially males, are particularly vulnerable because of their playful and explorative nature and considerable time spent in outdoor activities. Preventive measures, education about avoiding traditional first aid methods and early administration of ASV reduce complications, duration of hospital stay and avoid the use of antibiotics.

Acute encephalitis syndrome (AES) is a major public health challenge in India. We report here the epidemiology of sporadics and outbreaks of Japanese Encephalitis (JE) in Odisha state during 2012–2018. A total of 4235 AES cases (sporadics – 3394, outbreak cases – 841) recorded including 42 outbreaks; majority (n = 18) of which were during 2016. Overall JE virus (JEV) positivity was 11.78% (outbreak cases – 24.5%, sporadic cases – 8.6%). Age ≤15 years were largely affected during outbreaks, while 16–60 years population was dominant among sporadics. The major outbreak (2016) involved 336 patients from a tribal dominated district, spread over 173 villages. JEV seropositivity was high (43.45%) with 28.57% mortality. Epidemiological linkage with pig rearing was documented through JEV neutralizing antibodies in 50% of pig serum samples. Although the postvaccination period (2017–18) showed increase in AES case reporting but low JE proportion. Ongoing surveillance and preparedness of the health system would be of importance, especially in tribal-dominated districts.

Summary: Background: The phenotypical profile of cardiovascular malformations in patients with congenital rubella syndrome (CRS) is varied. We aimed to describe the profile of cardiac defects among CRS patients detected in the sentinel CRS surveillance in India during 2016–22. Methods: Sentinel sites enrolled infants with suspected CRS based on presence of cardiac defects, hearing impairment, eye signs, or maternal history of febrile rash illness. Suspected CRS cases underwent detailed systemic examination, including echocardiography and serological investigation for rubella. Cardiac defects were categorized as ‘Simple’ or ‘Complex’ as per the National Heart, Lung, and Blood Institute classification. We compared the distribution of cardiac defects among laboratory confirmed CRS cases and seronegative discarded cases. Findings: Of the 4578 suspected CRS cases enrolled by 14 sites, 558 (12.2%) were laboratory confirmed. 419 (75.1%) laboratory confirmed cases had structural heart defects (simple defects: n = 273, 65.2%, complex defects: n = 144, 34.4%), with ventricular septal defect (42.7%), atrial septal defect (39.4%), patent ductus arteriosus (36.5%), and tetralogy of Fallot as the commonest defects (4.5%). Laboratory confirmed CRS cases had higher odds of left to right shunt lesions (OR = 1.58, 95% CI: 1.15–2.17). This was mainly on account of a significant association of PDA with CRS (OR = 1.77, 95% CI: 1.42–2.21). Mortality was higher among CRS patients with complex heart defects (HR = 2.04, 95% CI: 1.26–3.30). Interpretation: Three-fourths of the laboratory confirmed CRS cases had structural heart defects. CRS patients with complex cardiac defects had higher mortality. Detecting CRS infection early and providing timely intervention for cardiovascular defects is critical for the management of CRS patients.

Background: In India, facility-based surveillance for congenital rubella syndrome (CRS) was initiated in 2016 to estimate the burden and monitor the progress made in rubella control. We analyzed the surveillance data for 2016–2021 from 14 sentinel sites to describe the epidemiology of CRS. Method: We analyzed the surveillance data to describe the distribution of suspected and laboratory confirmed CRS patients by time, place and person characteristics. We compared clinical signs of laboratory confirmed CRS and discarded case-patients to find independent predictors of CRS using logistic regression analysis and developed a risk prediction model. Results: During 2016–21, surveillance sites enrolled 3940 suspected CRS case-patients (Age 3.5 months, SD: 3.5). About one-fifth (n = 813, 20.6%) were enrolled during newborn examination. Of the suspected CRS patients, 493 (12.5%) had laboratory evidence of rubella infection. The proportion of laboratory confirmed CRS cases declined from 26% in 2017 to 8.7% in 2021. Laboratory confirmed patients had higher odds of having hearing impairment (Odds ratio [OR] = 9.5, 95% confidence interval [CI]: 5.6–16.2), cataract (OR = 7.8, 95% CI: 5.4–11.2), pigmentary retinopathy (OR = 6.7, 95 CI: 3.3–13.6), structural heart defect with hearing impairment (OR = 3.8, 95% CI: 1.2–12.2) and glaucoma (OR = 3.1, 95% CI: 1.2–8.1). Nomogram, along with a web version, was developed. Conclusions: Rubella continues to be a significant public health issue in India. The declining trend of test positivity among suspected CRS case-patients needs to be monitored through continued surveillance in these sentinel sites.

Rubella is a contagious disease caused by rubella virus leading to adverse outcomes among pregnant women including abortions, low birth weight, stillbirths and congenital rubella syndrome (CRS) in the baby. If not pregnant, the clinical manifestations are mild and self-limiting. In this hospital based cross-sectional study, 1985 blood samples were collected from females attending outpatient services of various hospitals to serologically detect Rubella infection. Rubella antibodies namely Immunoglobulin M (IgM)/Immunoglobulin G (IgG) were detected through enzyme linked immunosorbent assay (ELISA) or by identifying virus through polymerase chain reaction (PCR). From the total enrolled participants, 1951 samples were tested with age ranging from 16 to 38 years. Among the positive samples, about 60% patients had IgG antibodies as compared to less than 1% IgM and 0.40% by PCR. Out of 1951 samples, 7/849 (0.82%) and 651/1070 (60.8%) had IgM & IgG rubella antibodies respectively. The odds of having abortion was [OR-13.14 (4.94–34.97)] among anti-rubella positive and primi-gravida [OR-43.6 (5.9–322)] women. Therefore, vaccination of women against rubella before planning of pregnancy or at adolescence seems to be the need of hour to avoid the ill consequences during pregnancy as well as for the new born baby.

Introduction: India introduced a hepatitis-B (HB) vaccine in the Universal Immunization Program in 2002–2003 on a pilot basis, expanded to ten states in 2007–2008 (phase-1), and the entire country in 2011–2012 (phase-2). We tested sera from a nationally representative serosurvey conducted duing 2017, to estimate the seroprevalence of different markers of HB infection among children aged 5–17 years in India and to assess the impact of vaccination. Methods: We tested sera from 8273 children for different markers of HB infection and estimated weighted age-group specific seroprevalence of children who were chronically infected (HBsAg and anti-HBc positive), and immune due to past infection (anti-HBc positive and HBsAg negative), and having serological evidence of HB vaccination (only anti-HBs positive). We compared the prevalence of serological markers among children born before (aged 11–17 years) and after (aged 5-10 years) introduction of HB-vaccine from phase-1 states. Results: Among children aged 5–8 years, 1.1% were chronic carriers, 5.3% immune due to past infection, and 23.2% vaccinated. The corresponding proportions among children aged 9–17 years were 1.1%, 8.0%, and 12.0%, respectively. In phase-1 states, children aged 5–10 years had a significantly lower prevalence of anti-HBc (4.9% vs. 7.6%, p

Abstract Background From 2016, the Government of India introduced the oral rotavirus vaccine into the national immunization schedule. Currently, two indigenously developed vaccines (ROTAVAC, Bharat Biotech; ROTASIIL, Serum Institute of India) are included in the Indian immunization program. We report the rotavirus disease burden and the diversity of rotavirus genotypes from 2005 to 2016 in a multi-centric surveillance study before the introduction of vaccines. Methods A total of 29,561 stool samples collected from 2005 to 2016 (7 sites during 2005–2009, 3 sites from 2009 to 2012, and 28 sites during 2012–2016) were included in the analysis. Stools were tested for rotavirus antigen using enzyme immunoassay (EIA). Genotyping was performed on 65.8% of the EIA positive samples using reverse transcription- polymerase chain reaction (RT-PCR) to identify the G (VP7) and P (VP4) types. Multinomial logistic regression was used to quantify the odds of detecting genotypes across the surveillance period and in particular age groups. Results Of the 29,561 samples tested, 10,959 (37.1%) were positive for rotavirus. There was a peak in rotavirus positivity during December to February across all sites. Of the 7215 genotyped samples, G1P[8] (38.7%) was the most common, followed by G2P[4] (12.3%), G9P[4] (5.8%), G12P[6] (4.2%), G9P[8] (4%), and G12P[8] (2.4%). Globally, G9P[4] and G12P[6] are less common genotypes, although these genotypes have been reported from India and few other countries. There was a variation in the geographic and temporal distribution of genotypes, and the emergence or re-emergence of new genotypes such as G3P[8] was seen. Over the surveillance period, there was a decline in the proportion of G2P[4], and an increase in the proportion of G9P[4]. A higher proportion of mixed and partially typed/untyped samples was also seen more in the age group 0–11 months. Conclusions This 11 years surveillance highlights the high burden of severe rotavirus gastroenteritis in Indian children

Background: The nonzoonotic (nonsevere acute respiratory syndrome (SARS)/Middle East respiratory syndrome) human coronaviruses (HCoVs) are usually considered as the causative agent for acute respiratory infection. We studied the characteristics and outcome of children with non-SARS HCoV acute lower respiratory infection (ALRI). Methods: This was a cross-sectional study from a tertiary care teaching hospital in eastern India. Results: Of 137 samples tested positive for respiratory viruses, 13 were due to HCoV (7 boys, median age: 2 years). Cough was the most common symptom, followed by breathing difficulty and fever. An underlying comorbid condition present in 38.4%. Co-infection with other viruses was seen in 69% of cases. Chest radiograph was abnormal in 69.3% of children. Antibiotics were administered in 53.8%. The median length of hospitalization was 5 d, irrespective of underlying disease. There was no mortality. Conclusions: HCoV is an uncommon but increasingly recognized cause of ALRI in hospitalized children. No severe illness was found in children with underlying comorbidities. This study underscores the importance of HCoV in causation of childhood ALRI, necessitating a surveillance system in India.

BackgroundIndia has set a goal to eliminate measles and rubella/Congenital Rubella Syndrome (CRS) by 2023. Towards this goal, India conducted nationwide supplementary immunization activity (SIA) with measles-rubella containing vaccine (MRCV) targeting children aged between 9 months to MethodsWe conducted serosurveys in 2019-20 among pregnant women attending antenatal clinics of 6 hospitals, which were also sentinel sites for CRS surveillance, to estimate the prevalence of IgG antibodies against rubella. We systematically sampled 1800 women attending antenatal clinics and tested their sera for IgG antibodies against rubella. We used rubella seroprevalence data from the current survey and the survey conducted in 2017 among antenatal women from another 6 CRS surveillance sites to construct a catalytic models to estimate the incidence and burden of CRS.ResultThe seroprevalence of rubella antibodies was 82.3% (95% CI: 80.4-84.0). Rubella seropositivity did not differ by age group and educational status. Based on the constant and age-dependent force of infection models, we estimated that the annual incidence of CRS in India was 225.58 per 100,000 live births (95% CI: 217.49-232.41) and 65.47 per 100,000 live births (95% CI: 41.60-104.16) respectively. This translated to an estimated 14,520 (95% CI: 9,225-23,100) and 50,028 (95% CI: 48,234-51,543) infants with CRS every year based on age-dependent and constant force of infection models respectively.ConclusionsOur findings indicated that about one fifth of women in the reproductive age group in India were susceptible for rubella. The estimates of CRS incidence will serve as a baseline to monitor the impact of MRCV SIAs, as well progress towards the elimination goal of rubella/CRS.

Objectives: The objective is to study the clinico-epidemiological features of viral acute encephalitis syndrome (AES) cases and compare them with nonviral AES cases in children from Eastern India. Methods: This prospective observational study was conducted in the department of pediatrics of a tertiary care teaching hospital in Eastern India over 18-month period. Children (6 months to 15 years) with acute onset of fever (≥37.5°C) and a change in mental status (including symptoms such as confusion, disorientation, coma, or inability to talk) and/or new onset of seizures (excluding simple febrile seizures) were included in the study. The main outcome measures were the etiology and proportion attributed to viruses causing AES with clinical correlation. Results: Of 834 of clinically suspected AES cases, viral etiology could be confirmed in 136 (16.3%) cases (herpes simplex virus-1 [HSV-I] was most common). The 5–15 years' age group was most commonly affected (boys > girls). More cases occurred from July to November. The presence of rash and Glasgow Coma Scale

The aim of this study was to determine the causative agent of acute respiratory infections (ARIs) in hospitalized children, as well as investigate the characteristics of ARIs with single and multiple pathogens detection from July 2015 to June 2016. The objective of the present study was to examine the role of viruses, bacteria and mix infection of both in hospitalized children with ARI and their correlation with two divergent geographical settings of Odisha. Hospitalized children with ARI aged 1bacteria, 40(15%) with > 1virus, 22(8.2%) with > 2 bacteria and 20(7-4%) with both bacteria and virus. Most frequently detected pathogens were Klebsiella pneumonae, Setrptococcus pneumonae, Parainfluenza A and Influenza A virus. Incidences of pathogens were detected more among children

Up to 25% of hepatitis E virus (HEV)-infected pregnant women in their third trimester die. Despite HEV being an important cause of viral hepatitis, no robust surveillance exists in India. We reviewed jaundice outbreaks records and hospital records from jaundiced individuals seeking treatment and linked those records to laboratory results (HEV immunoglobulin M enzyme-linked immunosorbent assay) for January 2012 to September 2013 in Odisha state. A total of 14 HEV confirmed outbreaks were identified, of which 33% of 139 jaundiced cases were HEV positive. There were two deaths. An additional 495 jaundiced cases were identified through hospital records, of which 18% were HEV positive. Among HEV-positive women (n = 35), 34% were of childbearing age. While one may not be able to generalize our results, this finding suggests HE is widespread in Odisha and may represent hidden disease burden in this region. The policymakers should monitor HEV infections in similar geographical areas, especially among population of childbearing age women to initiate evidence-based control measures.

Summary: Background: The burden of dengue virus (DENV) infection across geographical regions of India is poorly quantified. We estimated the age-specific seroprevalence, force of infection, and number of infections in India. Methods: We did a community-based survey in 240 clusters (118 rural, 122 urban), selected from 60 districts of 15 Indian states from five geographical regions. We enumerated each cluster, randomly selected (with an Andriod application developed specifically for the survey) 25 individuals from age groups of 5–8 years, 9–17 years, and 18–45 years, and sampled a minimum of 11 individuals from each age group (all the 25 randomly selected individuals in each age group were visited in their houses and individuals who consented for the survey were included in the study). Age was the only inclusion criterion; for the purpose of enumeration, individuals residing in the household for more than 6 months were included. Sera were tested centrally by a laboratory team of scientific and technical staff for IgG antibodies against the DENV with the use of indirect ELISA. We calculated age group specific seroprevalence and constructed catalytic models to estimate force of infection. Findings: From June 19, 2017, to April 12, 2018, we randomly selected 17 930 individuals from three age groups. Of these, blood samples were collected and tested for 12 300 individuals (5–8 years, n=4059; 9–17 years, n=4265; 18–45 years, n=3976). The overall seroprevalence of DENV infection in India was 48·7% (95% CI 43·5–54·0), increasing from 28·3% (21·5–36·2) among children aged 5–8 years to 41·0% (32·4–50·1) among children aged 9–17 years and 56·2% (49·0–63·1) among individuals aged between 18–45 years. The seroprevalence was high in the southern (76·9% [69·1–83·2]), western (62·3% [55·3–68·8]), and northern (60·3% [49·3–70·5]) regions. The estimated number of primary DENV infections with the constant force of infection model was 12 991 357 (12 825 128–13 130 258) and for the age-dependent force of infection model was 8 655 425 (7 243 630–9 545 052) among individuals aged 5–45 years from 30 Indian states in 2017. Interpretation: The burden of dengue infection in India was heterogeneous, with evidence of high transmission in northern, western, and southern regions. The survey findings will be useful in making informed decisions about introduction of upcoming dengue vaccines in India. Funding: Indian Council of Medical Research.

Abstract Human Papillomavirus is the major etiological agent in the development of cervical cancer but not a sufficient cause. Despite significant research, the underlying mechanisms of progression from a low-grade squamous intraepithelial lesion to high grade squamous intraepithelial lesion are yet to be understood. Deregulation of viral gene expression and host genomic instability play a central role in virus-mediated carcinogenesis. Key events such as viral integration and epigenetic modifications may lead to the deregulation of viral and host gene expression. This review has summarized the available literature to describe the possible mechanism and role of viral integration in mediating carcinogenesis. HPV integration begins with DNA damage or double strand break induced either by oxidative stress or HPV proteins and the subsequent steps are driven by the DNA damage responses. Inflammation and oxidative stress could be considered as cofactors in stimulating viral integration and deregulation of cellular and viral oncogenes during the progression of cervical carcinoma. All these events together with the host and viral genetic and epigenetic modifications in neoplastic progression have also been reviewed which may be relevant in identifying a new preventive therapeutic strategy. In the absence of therapeutic intervention for HPV-infected individuals, future research focus should be directed towards preventing and reversing of HPV integration. DNA damage response, knocking out integrated HPV sequences, siRNA approach, modulating the selection mechanism of cells harboring integrated genomes and epigenetic modifiers are the possible therapeutic targets.

Once interruption of transmission of lymphatic filariasis is achieved, morbidity prevention and management becomes more important. A study in Brugia malayi filariasis from India has shown sub-clinical lymphatic pathology with potential reversibility. We studied a Wuchereria bancrofti infected population, the major contributor to LF globally.Children aged 5-18 years from Odisha, India were screened for W. bancrofti infection and disease. 102 infected children, 50 with filarial disease and 52 without symptoms were investigated by lymphoscintigraphy and then randomized to receive a supervised single oral dose of DEC and albendazole which was repeated either annually or semi-annually. The lymphatic pathology was evaluated six monthly for two years.Baseline lymphoscintigraphy showed abnormality in lower limb lymphatics in 80% of symptomatic (40/50) and 63·5% (33/52) of asymptomatic children. Progressive improvement in baseline pathology was seen in 70·8, 87·3, 98·6, and 98·6% of cases at 6, 12, 18, and 24 months follow up, while in 4·2, 22·5, 47·9 and 64·8%, pathology reverted to normal. This was independent of age (p = 0·27), symptomatic status (p = 0·57) and semi-annual/bi-annual dosing (p = 0·46). Six of eleven cases showed clinical reduction in lymphedema of legs.A significant proportion of a young W. bancrofti infected population exhibited lymphatic pathology which was reversible with annual dosage of DEC and albendazole. This provides evidence for morbidity prevention & treatment of early lymphedema. It can also be used as a tool to improve community compliance during mass drug administration.ClinicalTrials.gov No CTRI/2013/10/004121.

HPV is the major causative agent for cervical cancer. Study on the risk of cervical cancer associated with different hr-HPV genotypes would be useful for disease management and new vaccine strategy. With limited reports available, the present study aimed to investigate the pattern of HPV genotypes coinfections and risk of cervical carcinoma associated with them in Indian population. 15 HPV genotypes were detected by E6/E7 multiplex nested type-specific PCR in the HPV-positive cervical samples of 172 cervical cancer cases and 174 subjects with normal cytology. Association between the genotypes and cervical cancer was estimated by calculating the Odds ratio and 95% confidence interval. Risk of cervical carcinoma was associated with multiple genotypes excluding HPV16 (OR:5.87; 95% CI-1.28-26-29; p = .02), multiple genotypes excluding HPV18 (OR = 2.5; 95% CI = 1.09-6.05; p = .03), multiple genotypes of α9 species(OR = 5.3 95% CI = 1.14-24.03; p = .007), and multiple genotypes of α7 species (OR = 2.5; 95% CI = .49-13.45; p = .2). Genotypes not targeted by quadrivalent vaccine types (OR = 2.94 95% CI = 1.48-5.80; p = .001) conferred 2.94 fold higher risk of cervical carcinoma. Cases those coinfected with phylogenetically related genotypes (OR = 2.29; 95% CI(.69-7.59) p = .17) were at 2.9 fold higher risk of invasive cervical carcinoma than those infected with other genotypes although it is not statistically significant. Whereas phylogenetically unrelated genotypes coinfection is negatively associated with cervical carcinoma (OR = .44 95% CI (.244-.8) p = .007) and it is statistically significant.Genotypes not targeted by 9-valent vaccines (OR = .40; 95% CI = .19-.85; p = .017) associated with lesser risk of cervical carcinoma as compared to other genotypes. Subjects infected with any HPV genotype/genotypes excluding HPV16 in association with HPV 18 (OR = 4.1; 95% CI = 1.81-9.25 P = < .001) were at 4.1 fold higher risk of developing invasive cervical carcinoma.In conclusion, the risk of development of cervical cancer is genotype specific and might be associated with type-specific interactions between the genotypes in multiple infections.

Background. Acute respiratory infections (ARIs) are important cause of mortality and morbidity in children under five in developing country. Methods. This observational study was conducted over two-year period in a tertiary care teaching hospital of Eastern India. Nasal and throat swabs were collected, transported to the laboratory at 2–8°C in viral transport media, and then processed for detection of viruses using mono/multiplex real-time polymerase chain reaction. Results. A total of 300 children aged 2–60 months with ARIs were included. The most common age group affected with LRI was 2–12 mo and with URI was >12–60 mo. Viruses were detected in 248 cases. In URI, 77 were positive for single virus and 19 were positive for more than one virus; in LRI, 113 were positive for single virus and 12 were positive for more than one virus. The most common viruses isolated from URI cases were rhinovirus and adenovirus. The most common viruses isolated from LRI cases were respiratory syncytial virus and influenza virus. Most cases occurred in the months of January, December, and August. Conclusion. Viruses constitute a significant cause of ARI in children under five. RSV, ADV, RV, and IFV were the most prevalent viruses isolated.

Although current programmes to eliminate lymphatic filariasis have made significant progress it may be necessary to use different approaches to achieve the global goal, especially where compliance has been poor and 'hot spots' of continued infection exist. In the absence of alternative drugs, the use of higher or more frequent dosing with the existing drugs needs to be explored. We examined the effect of higher and/or more frequent dosing with albendazole with a fixed 300 mg dose of diethylcarbamazine in a Wuchereria bancrofti endemic area in Odisha, India. Following screening, 104 consenting adults were randomly assigned to treatment with the standard regimen annually for 24 months (S1), or annually with increased dose (800 mg albendazole)(H1) or with increased frequency (6 monthly) with either standard (S2) or increased (H2) dose. Pre-treatment microfilaria counts (GM) ranged from 348 to 459 mf/ml. Subjects were followed using microfilaria counts, OG4C3 antigen levels and ultrasound scanning for adult worm nests. Microfilarial counts tended to decrease more rapidly with higher or more frequent dosing at all time points. At 12 months, Mf clearance was marginally greater with the high dose regimens, while by 24 months, there was a trend to higher Mf clearance in the arm with increased frequency and 800 mg of albendazole (76.9%) compared to other arms, (S1:64%, S2:69.2% & H1:73.1%). Although higher and/or more frequent dosing showed a trend towards a greater decline in antigenemia and clearance of "nests", all regimens demonstrated the potential macrofilaricidal effect of the combination. The higher doses of albendazole did not result in a greater number or more severe side effects. The alternative regimens could be useful in the later stages of existing elimination programmes or achieving elimination more rapidly in areas where programmes have yet to start.

Background: India accounts for more than one-fifth of the world's tuberculosis (TB) burden. In spite of efforts taken by the Revised National Tuberculosis Control Programme, tribal areas of the state of Odisha report a high TB incidence over the years. One of the reasons could be delay in reporting to health facilities by the symptomatic patients. During such delays an active case may infect numerous susceptible people thereby contributing to the perpetuation of the infection. The delay in diagnosis may be as long as 2–3 months and even more in hard-to-reach areas. Objective The present study aims to find out the extent of delay in diagnosis among pulmonary TB patients of a tribal dominated district that may help in planning effective control strategies for similar situations. Methods: The information on delay in diagnosis is part of a cross-sectional drug resistance study carried out from June 2011 to May, 2013 in 20 Designated Microscopy Centres (DMCs) of Rayagada district of Odisha, India. Out of 634 smear positive pulmonary TB patients enrolled in this study, information on health seeking by the patients were available for 580 patients. The patients included had clinical signs and symptoms suggestive of pulmonary TB (cough, chest pain, and hemoptysis), with/without radiological evidence. Patients found smear positive by Ziehl–Neelsen microscopy were requested to take part in the study and accordingly a written questionnaire including history of: TB treatment; symptoms experienced by the patient and duration of suffering; and radiological examination was completed. The delay in diagnosis at the DMCs due to delay in health seeking by the symptomatic TB patients was evident as only 5.2% patients reported within 2 weeks and 62.6% up to 1 month of onset of symptoms. Results: The delay in health seeking by the patients was not differentiated by sex or resistance profile, although more men attended the DMC for diagnosis. The present study is the first of its kind to report diagnostic delay of TB among smear-positive TB patients of Rayagada, a tribal-dominated district of Odisha, India and it reveals an extremely long diagnostic delay of TB in this area. We found that 12.9% of patients had a delay exceeding 2 months, and 50% of them had high sputum grade. This is a serious concern due to the fact that each of these patients dispenses up to 3500 bacilli in each cough, and may infect 10–15 people each year, eventually creating a public health problem. Conclusion: Poor awareness of patients about the disease and limited access to health care are the bottom-line in apparent diagnostic delay of TB patients. This substantial patient delay to diagnosis is a major contributing factor for increasing transmission of TB in tribal districts of Odisha. Increased awareness of the disease is crucial in improving health-seeking behavior in these areas.

Cervical cancer is the fourth most common cancer in women worldwide. It is well known that high-risk HPV is the main etiological agent for this infectious viral carcinoma. Human papillomaviruses are small (50 nm) double-stranded DNA viruses composed of a genome of 8 kilobase pair, enclosed inside a non-enveloped capsid protein. The genome includes three portions: (a) early genes (E1, E2, E4, E5, E6, E7) those regulate the vegetative and productive phase of viral life cycle; (b) late genes (L1, L2) which encode the capsid protein and (c) a noncoding regulatory region called long control region (LCR) involved in the regulation of viral replication and transcription. The HPV oncoproteins E6 and E7 recognize numerous host proteins, in large part by hijacking cellular domain-motif interaction networks. E6 and E7 oncoproteins disrupt cell cycle checkpoint control by inhibiting CDKs inhibitors (P21, P27) and degrading P53. In the process of E6 mediated degradation, E6 binds to a short leucine (L)-rich LxxLL consensus sequence within the cellular ubiquitin ligase E6AP3. Subsequently, the E6/E6AP heterodimer recruits and degrades p53. The LxxLL peptide of E6AP is sufficient to render E6 liable to interact with p53 ‘core’ (DNA binding) domain of p53 required for the interaction with E6/E6AP9–11. In the present study, we explored specific novel inhibitors targeting three different druggable pocket i.e., E6-binding cleft, LxxLL pocket of AP and the p53-binding cleft of E6/E6AP/p53 ternary complex using AutoDock tool. A total of five novel compounds with higher binding energy were identified as potential competitive inhibitors against HPV16 E6/AP/P53 ternary complex. The combinatorial strategies targeting these druggable pockets are expected to open up better avenues for the development of therapeutic strategies against HPV-mediated oncogenesis in near future.
