Antibody (IgA, IgG, and IgG Subtype) Responses to SARS-CoV-2 in Severe and Nonsevere COVID-19 Patients

For the assessment of vaccine-induced immune response and to understand the role of antibodies in neutralization, it is necessary to assess dynamics of various antibodies in patients with different clinical manifestations. This study aims to quantitate circulating levels of IgA/IgG and IgG subtypes induced at different days postonset of symptoms, in severe and nonsevere patients. For this, serum or plasma samples (n = 146) collected from 79 COVID-19 patients were used. Indirect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific IgA, IgG, and IgG subtype specific enzyme-linked immunosorbent assays (ELISAs) were performed. Antibody titers between severe and nonsevere patients were compared at different times postonset of clinical symptoms. Titers in ELISA were compared to neutralizing antibody (Nab) titers determined by plaque reduction neutralization test (PRNT). Over 75% patients were positive for IgA/IgG antibodies in the first week. The ELISA titers did not differ during the first week; however, severe disease exhibited raised titers thereafter. Nab titers correlated with the ELISA titers in mild presentation but not in severe disease. IgA and IgG1 antibodies correlated stronger with Nabs. The findings highlighted that IgA together with IgG play an important in SARS-CoV-2 neutralization. These results will prove useful in assessing efficacy of vaccines and understanding disease pathogenesis.

Implementation of the Comprehensive Unit-Based Safety Program to Improve Infection Prevention and Control Practices in Four Neonatal Intensive Care Units in Pune, India

Objective: To implement the Comprehensive Unit-based Safety Program (CUSP) in four neonatal intensive care units (NICUs) in Pune, India, to improve infection prevention and control (IPC) practices. Design: In this quasi-experimental study, we implemented CUSP in four NICUs in Pune, India, to improve IPC practices in three focus areas: hand hygiene, aseptic technique for invasive procedures, and medication and intravenous fluid preparation and administration. Sites received training in CUSP methodology, formed multidisciplinary teams, and selected interventions for each focus area. Process measures included fidelity to CUSP, hand hygiene compliance, and central line insertion checklist completion. Outcome measures included the rate of healthcare-associated bloodstream infection (HA-BSI), all-cause mortality, patient safety culture, and workload. Results: A total of 144 healthcare workers and administrators completed CUSP training. All sites conducted at least 75% of monthly meetings. Hand hygiene compliance odds increased 6% per month [odds ratio (OR) 1.06 (95% CI 1.03-1.10)]. Providers completed insertion checklists for 68% of neonates with a central line; 83% of checklists were fully completed. All-cause mortality and HA-BSI rate did not change significantly after CUSP implementation. Patient safety culture domains with greatest improvement were management support for patient safety (+7.6%), teamwork within units (+5.3%), and organizational learning-continuous improvement (+4.7%). Overall workload increased from a mean score of 46.28 ± 16.97 at baseline to 65.07 ± 19.05 at follow-up (p < 0.0001). Conclusion: CUSP implementation increased hand hygiene compliance, successful implementation of a central line insertion checklist, and improvements in safety culture in four Indian NICUs. This multimodal strategy is a promising framework for low- and middle-income country healthcare facilities to reduce HAI risk in neonates.

Anti-SARS-CoV-2 IgG antibody response among Indian COVID-19 patients using β-propiolactone-inactivated, whole virus-based indirect ELISA

BACKGROUND

Coronavirus disease 2019 (COVID-19) pandemic caused by infection with severe acute respiratory syndrome - coronavirus-2 (SARS-CoV-2) continues to affect many countries and large populations. Serologic assays for antibody detection aid patient diagnosis and seroepidemiologic investigations.

METHODS

An indirect IgG ELISA was developed indigenously using β-propiolactone (BPL) inactivated SARS-CoV-2. This assay was used for screening 200 healthy donor sera collected prior to COVID-19 emergence (2017-2019), 185 serum/plasma samples of confirmed COVID-19 patients (n = 137) and 57 samples of viral RNA positive asymptomatic contacts (n = 51). The IgG response was studied in relation to duration and severity of illness.

RESULTS

The ELISA demonstrated 97 % specificity and IgG detection in >50 %, 80 %, 93.8 % and 100 % of the patients respectively during the first, second, third and fourth week of illness. IgG detection rate was higher in patients with severe disease (SD, 90.9 %) than those with mild disease (MD, 68.8 %) during the second week of illness (P = 0.027). IgG seropositivity among asymptomatic contacts was 64.7 %. IgG ELISA absorbance values were higher in SD than MD patients during the first 2 weeks of illness (P < 0.05). No significant difference was observed between the absorbance values of asymptomatic subjects and MD patients (P = 0.94).

CONCLUSION

The BPL inactivated virus-based ELISA could detect IgG antibodies early and in a significant proportion of COVID-19 patients suggesting its potential utility as a supplement to the currently used viral RNA detection tests in patient diagnosis and contact screening algorithms.

Prevalence and determinants of undernutrition among under-five children residing in urban slums and rural area, Maharashtra, India: a community-based cross-sectional study

BACKGROUND

Undernutrition among under five children in India is a major public health problem. Despite India's growth in the economy, the child mortality rate due to undernutrition is still high in both urban and rural areas. Studies that focus on urban slums are scarce. Hence the present study was carried out to assess the prevalence and determinants of undernutrition in children under five in Maharashtra, India.

METHODS

A community-based cross-sectional study was conducted in 16 randomly selected clusters in two districts of Maharashtra state, India. Data were collected through house to house survey by interviewing mothers of under five children. Total 2929 mothers and their 3671 under five children were covered. Multivariate logistic regression analysis was carried out to identify the determinants of child nutritional status seperately in urban and rural areas.

RESULTS

The mean age of the children was 2.38 years (±SD 1.36) and mean age of mothers was 24.25 years (± SD 6.37). Overall prevalence of stunting among children under five was 45.9%, wasting was 17.1 and 35.4% children were underweight. Prevalence of wasting, stunting and underweight were more seen in an urban slum than a rural area. In the rural areas exclusive breast feeding (p < 0.001) and acute diarrhea (p = 0.001) were associated with wasting, children with birth order 2 or less than 2 were associated with stunting and exclusive breast feeding (p < 0.05) and low maternal education were associated with underweight. Whereas in the urban slums exclusive breast feeding (p < 0.05) was associated with wasting, sex of the child (p < 0.05) and type of family (p < 0.05) were associated with stunting,and low income of the family (p < 0.05) was associated with underweight.

CONCLUSIONS

Factors like sex of the child, birth order,exclusive breast feeding,economic status of the family, type of family,acute diarrhea and maternal education have influence on nutritional status of the child. Improvement of maternal education will improve the nutritional status of the child. Strategies are needed to improve the economic status of the community.

Association of preeclampsia with anthropometric measures and blood pressure in Indian children

BACKGROUND AND OBJECTIVE

Birth weight and post-natal growth are important predictors of adult health. Preeclampsia (PE) is associated with low birth weight and may have long term effects on the health of the children. The current study aims to compare anthropometry and blood pressure between children of mothers with and without PE in an Indian cohort.

METHODS

We studied children born to women with (PE; n = 211) and without preeclampsia (non-PE; n = 470) at Bharati Hospital, Pune, India. Anthropometry and blood pressure were measured in children at 3-7 years of age. Weight and height Z-scores were calculated using the WHO 2006 growth reference. Independent t-tests were used to compare means between the two groups, and associations between preeclampsia and child outcomes were analyzed using multiple linear regression, adjusting for potential confounders.

RESULTS

Weight and height Z-scores (p = 0.04 and 0.008), and subscapular skinfold thickness (p = 0.03) were higher among children of PE compared with children of non-PE mothers. Systolic blood pressure was also higher in children of PE mothers (1.70 mmHg [95% CI 0.05, 2.90] p = 0.006). BMI and diastolic blood pressure did not differ between groups. In regression models adjusted for newborn weight and gestational age, current age and sex, and maternal height, BMI and socio-economic status, children of PE mothers had higher weight Z-score (0.27 SD [95%CI 0.06, 0.48] p = 0.01), height Z-score (0.28 SD [95%CI 0.09, 0.47] p = 0.005), and subscapular skinfold thickness (0.38 mm [95%CI 0.00, 0.76] p = 0.049). A trend for higher systolic blood pressure (1.59 mmHg [95%CI -0.02, 3.20] p = 0.053) in the children was also observed in the adjusted model. The difference in systolic blood pressure was attenuated after adjusting further for the child's weight and height (1.09 mmHg [95%CI -0.48, 2.67] p = 0.17). There was no evidence of differences in effects between boys and girls.

CONCLUSION

Children of PE mothers were taller and heavier, and had higher systolic blood pressure, partly explained by their increased body size, than children of non-PE mothers. In utero exposure to preeclampsia may increase the risk of future cardiovascular disease.

Efficacy, Immunogenicity, and Safety of a 9-Valent Human Papillomavirus Vaccine: Subgroup Analysis of Participants From Asian Countries

Background

A 9-valent human papillomavirus-6/11/16/18/31/33/45/52/58 (9vHPV) vaccine extends coverage to 5 next most common oncogenic types (31/33/45/52/58) in cervical cancer versus quadrivalent HPV (qHPV) vaccine. We describe efficacy, immunogenicity, and safety in Asian participants (India, Hong Kong, South Korea, Japan, Taiwan, and Thailand) from 2 international studies: a randomized, double-blinded, qHPV vaccine-controlled efficacy study (young women aged 16–26 years; NCT00543543; Study 001); and an immunogenicity study (girls and boys aged 9–15 years; NCT00943722; Study 002).

Methods

Participants (N = 2519) were vaccinated at day 1 and months 2 and 6. Gynecological samples (Study 001 only) and serum were collected for HPV DNA and antibody assessments, respectively. Injection-site and systemic adverse events (AEs) were monitored. Data were analyzed by country and vaccination group.

Results

9vHPV vaccine prevented HPV-31/33/45/52/58–related persistent infection with 90.4%–100% efficacy across included countries. At month 7, ≥97.9% of participants seroconverted for each HPV type. Injection-site AEs occurred in 77.7%–83.1% and 81.9%–87.5% of qHPV and 9vHPV vaccine recipients in Study 001, respectively, and 62.4%–85.7% of girls/boys in Study 002; most were mild to moderate.

Conclusions

The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Asian participants. Data support 9vHPV vaccination programs in Asia.

Age-stratified anti-HAV positivity in Pune, India after two decades: Has voluntary vaccination impacted overall exposure to HAV?

The degree of transmission of hepatitis A virus (HAV) is inversely proportional to the socioeconomic status of a community. Serosurveys conducted at Pune, India during 1982-98 documented significant reduction in HAV exposure of paediatric, higher socioeconomic status (HSS) population. Anti-HAV positivity (ELISA) in age-stratified Pune population representing HSS and lower middle socioeconomic status (LMSS) (n = 1065) and infants till the age of 15 months (n = 690) was determined in 2017. Anti-HAV positivity in the LMSS population decreased significantly in 2017 while an increase was seen in the HSS category. The surprising rise in anti-HAV positivity in the HSS population reflected vaccine- and infection-induced antibodies while only infection-induced antibodies were present in the LMSS category. Lowest antibody prevalence in infants was at 12 months, the recommended age for hepatitis A vaccination. Improved hygiene and selective immunization practices impacted HAV exposure of the LMSS population. The data emphasize the need for hepatitis A vaccination irrespective of socioeconomic status.

Seroepidemiology of respiratory syncytial virus in western India with special reference to appropriate age for infant vaccination

Respiratory syncytial virus (RSV) causes significant infant mortality worldwide and a vaccine may be available soon. This study determined age-stratified anti-RSV antibody positivity (enzyme-linked immunosorbent assay [ELISA]) at Pune, India (cord blood-85 years). Antibody positivity declined from 100% at birth to 71.3% (3 months), and 0.7% (6 months). A significant rise was noted at 15 months (16%), 16 to 24 months (64.5%) and 4 years (95.2%) with concomitant IgM-anti-RSV positivity indicative of recent infection. Antibody decline was higher in infants born preterm than full-term. Across subsequent age groups including the elderly, antibody positivity was similar and comparable, suggestive of repeated exposure to the virus. Early protection/vaccination is essential for the infant population.

Clinical study of safety and immunogenicity of pentavalent DTP-HB-Hib vaccine administered by disposable-syringe jet injector in India

Introduction

We conducted a randomized, observer-blind, non-inferiority, parallel-group clinical study of diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type b conjugate (pentavalent) vaccination of infants in India. Goals were to determine whether the seropositivity rate after vaccination via disposable-syringe jet injector (DSJI) was non-inferior to that via needle and syringe (N-S), and to compare the safety of vaccination by the two methods.

Methods

Healthy children received a three-dose series of vaccine intramuscularly by DSJI or N-S beginning at 6–8 weeks of age. Immunoglobulin G antibody levels were measured by ELISA at 4–6 weeks after the third dose. The main secondary endpoint was safety, measured as injection site and systemic reactions.

Discussion

The study was stopped early out of caution beyond that specified in the protocol stopping criteria, after the Data Safety Committee noted a higher frequency of injection site reactions, especially moderate and severe, in the DSJI group. As a result, 128 subjects—DSJI group 61; N-S group 67—completed the study, rather than the 340 planned, and the study was not sufficiently powered to compare immunogenicity endpoints for the groups. Descriptive statistics indicate that seropositivity induced by vaccination with the DSJI was similar to that of N-S for all five antigens. Pentavalent vaccine includes whole-cell pertussis vaccine and an aluminum adjuvant, which may have contributed to the higher number of local reactions with the DSJI. The reactions caused no serious or long-term sequelae, and may be more acceptable in other populations or circumstances.

Reported incidence and risk factors of childhood pneumonia in India: a community-based cross-sectional study

Background

Pneumonia is responsible for high morbidity and mortality amongst children under five year of age. India accounts for one-third of the total WHO South East Asia burden of under-five mortality. There is a paucity of epidemiological studies indicating the true burden of pneumonia. Identification of the risk factors associated with pneumonia will help to effectively plan and implement the preventive measures for its reduction.

Methods

It was a descriptive cross-sectional study conducted in 16 randomly selected clusters in two districts of Maharashtra state, India. All mothers of under-five children in the selected clusters were included. A validated pretested interview schedule was filled by trained field supervisors through the house to house visits.WHO definition was used to define and classify clinical pneumonia. Height and weight of children were taken as per standard guidelines. Quality checks for data collection were done by the site investigators and critical and noncritical fields in the questionnaire were monitored during data entry. For continuous variables mean and SD were calculated. Chi-square test was applied to determine the association between the variables. Level of significance was considered at 0.05.

Results

There were 3671 under five-year children, 2929 mothers in 10,929 households.Unclean fuel usage was found in 15.1% of households. Mean birth weight was 2.6 kg (SD;0.61). Exclusive breastfeeding till 6 months of age was practiced by 46% of mothers. Reported incidence of ARI was 0.49 per child per month and the reported incidence of pneumonia was 0.075 per child per year. It was not associated with any of the housing environment factors (p > 0.05) but was found to be associated with partial immunization (p < 0.05). Poor practices related to child feeding, hand hygiene and poor knowledge related to signs and symptoms of pneumonia amongst mother were found.

Conclusions

Very low incidence of pneumonia was observed in Pune and Sangli districts of Maharashtra. Partial immunization emerged as a most important risk factor. Reasons for low incidence and lack of association of pneumonia with known risk factors may be a better literacy rate among mothers and better immunization coverage.

Effect of informed consent on patients undergoing gastrointestinal surgery and living donor liver transplantation and on their relatives in a developing country

Background

Informed consent is a systematic process for obtaining permission before conducting a healthcare intervention. In a developing country, gaining informed consent is generally perceived to be a ritual only to comply with legal requirements. The present study examined this by assessing the process of informed consent in patients undergoing gastrointestinal surgery or living donor liver transplantation (LDLT) and their relatives, based on their comprehension and overall satisfaction, in India.

Methods

All patients undergoing any gastrointestinal surgery or LDLT procedure between August 2015 and July 2016 and their relatives were included, and were administered a structured questionnaire 5 days after the procedure.

Results

The majority of patients (94·2 per cent) could recall the nature of their disease, the surgery performed (81·6 per cent) and anticipated complications (55·6 per cent). Among their relatives, these proportions were 97·8, 87·3 and 58·5 per cent respectively. Recall was associated with age, occupation and education among both patients and relatives. Patients undergoing LDLT, their donors and their relatives had better recall than those who had other gastrointestinal procedures (P < 0·001). Many patients found the process of informed consent useful and reassuring.

Conclusion

The details and risks of an operation were understood by most of the patients, especially those undergoing liver transplantation. Patients from developing countries can generally understand ‘informed consent’, and value it.

Does the presence of Klebsiella pneumoniae carbapenemase and New Delhi metallo-β-lactamase-1 genes in pathogens lead to fatal outcome?

INTRODUCTION

Infections due to multidrug-resistant (MDR) pathogens are a medical challenge. There is considerable apprehension among clinicians regarding pathogens reported as carrying New Delhi metallo-β-lactamase-1 (NDM) and Klebsiella pneumoniae carbapenemase (KPC) genes from their patients. In the face of extremely high rates of antimicrobial resistance, it is essential to gauge the clinical significance of isolation of pathogens carrying these genes from clinical samples. This study compares the outcome of patients infected with pathogens carrying NDM/KPC genes versus those without these genes.

METHODS

The study was conducted over a 1-year period at a Level-1 trauma centre. Hospital-acquired infections were diagnosed on the basis of CDC's criteria. The correlation of isolation of a multi-resistant pathogen carrying KPC or NDM genes with the clinical outcome was ascertained.

RESULTS

A total of 276 consecutive patients admitted to the Intensive Care Units/wards of the JPNA Trauma Centre were included in this study. Of the 371 isolates recovered from these patients, 116 were from patients who had a fatal outcome. The difference in prevalence of blaNDMand blaKPCwas not significant in any genera of Gram-negative pathogens isolated from patients who survived versus those who had a fatal outcome.

CONCLUSION

Isolation of MDR pathogens carrying NDM/KPC genes from clinical samples is not always a harbinger of a fatal outcome. Efforts should be made to prevent cross-transmission of these pathogens.

Invasive pneumococcal disease in children aged younger than 5 years in India: a surveillance study

BACKGROUND

Invasive pneumococcal disease continues to be a major cause of morbidity and mortality among children younger than 5 years of age in India. We aimed to provide nationally representative data for the pattern of disease due to Streptococcus pneumoniae, trends in the serotype of invasive pneumococci, and invasive pneumococci antimicrobial resistance patterns, in India.

METHODS

In this prospective hospital-based and retrospective laboratory-based surveillance study, we prospectively enrolled children aged younger than 5 years with suspected or proven invasive pneumococcal disease from 18 hospitals or institutional centres and retrospectively included laboratory-confirmed pneumococcal isolates from ten sentinel laboratories, together representing 11 states in India. Eligibility criteria were fever higher than 38°C without localising symptoms, clinical presentation of suspected meningitis or pneumonia, and evidence of radiographic pneumonia. We cultured blood and other normally sterile body fluids, reconfirmed and serotyped pneumococcal isolates, and established antimicrobial susceptibility using standard study protocols.

FINDINGS

Between Jan 1, 2011, and June 30, 2015, we enrolled 4377 patients. Among 361 (8%) patients with culture-proven pneumococcal disease, all clinical data were known for 226 (63%); among these patients, 132 (58%) presented with pneumonia, 78 (35%) presented with meningitis, and 16 (7%) had other clinical conditions. 131 (3%) died overall and 29 (8%) patients with invasive pneumococcal disease died. Serotypes 14 (52 [14%] of 361), 1 (49 [14%]), 5 (37 [10%]), and 19F (33 [9%]) were the most common. Penicillin non-susceptibility occurred in isolates from 29 (8%) patients, co-trimoxazole resistance occurred in 239 (66%), erythromycin resistance occurred in 132 (37%), and chloramphenicol resistance occurred in 33 (9%). We found multidrug resistance in 33 (9%) of 361 patients.

INTERPRETATION

The proportion of positive blood cultures, number of isolates, geographical representation, and data generated over the 4·5 years of the study are representative of data for most of India. Continued surveillance is warranted as the decision to introduce protein conjugated vaccine in India is made.

Immunogenicity and Safety of a Liquid Hexavalent Vaccine in Indian Infants

OBJECTIVE

To evaluate the immunogenicity and safety of a fully liquid, hexavalent diphtheria-tetanus-acellular pertussis-inactivated poliovirus-hepatitis B-Haemophilus influenzae type b (DTaP-IPV- HB-PRP~T) vaccine in Indian infants.

DESIGN

Phase III, single-arm study.

SETTING

Two tertiary care hospitals.

PARTICIPANTS

177 healthy, 6-week-old infants.

INTERVENTION

All participants received hepatitis B vaccine and Oral polio vaccine (OPV) at birth and DTaP-IPV-HB-PRP~T at 6, 10, 14 weeks of age.

MAIN OUTCOME MEASURES

Serum was analyzed for immune responses to all antigens 1 month post- 3rd dose; safety was assessed for 30 minutes post-vaccination, and for 7 days (solicited reactions) and 30 days (unsolicited events).

RESULTS

Seroprotection rates were 100% for anti-HB (>10 mIU/mL), anti-PRP (>0.15 ug/mL), anti-T (>0.01 IU/mL), anti-polio 1, 2, and 3 (>8 [1/dil]), and 99.3% for diphtheria (>0.01 IU/mL). For the pertussis antigens, vaccine response rate was 93.8% for anti-PT and 99.3% for anti-FHA. 37.9% and 54.6% of participants experienced at least one solicited injection site and systemic reaction, respectively, and 20.3% of participants experienced at least one unsolicited event (none of which was related to the vaccination). Four serious adverse events (including one death) were reported, but none was related to the vaccination.

CONCLUSION

The fully liquid DTaP-IPV-HB-PRP~T vaccine is highly immunogenic in infants in India when administered in a 6, 10, 14 week schedule along with HB and OPV administered at birth, and was well tolerated.

Altered breast milk components in preeclampsia; An in-vitro proton NMR spectroscopy study

OBJECTIVE

To investigate the metabolic profile of milk on day 3 and at the 6th month of lactation in mothers with preeclampsia (PE) and normotensive mothers.

STUDY DESIGN

Women with PE (n=29) and control women (n=31) were recruited for this study. Milk was collected on day 3 and at the 6th month of lactation. Proton NMR spectroscopy was used to identify 25 milk metabolites (alpha-lactose, beta-lactose, oligosaccharides, myo-inositol, alanine, glutamate, glutamine, glycine, histidine, isoleucine, leucine, lysine, phenylalanine, tyrosine, valine, acetone, citrate, creatine, phosphocreatine, acetate, choline, lactate, lipid, phosphocholine and glycerophosphocholine). Principle component analysis (PCA) and Partial Least Square Discriminant Analysis (PLS-DA) were carried out to identify differences in milk metabolite composition between both the groups.

RESULTS

The levels of milk metabolites varied between the control and PE groups. Alpha and beta-lactose, glycine, glycerophosphocholine (p<0.01 for all); glutamate, glutamine and phosphocholine levels (p<0.05 for all) were increased at the 6th month as compared to day 3 of lactation in the control group. However, in the PE group, only glycerophosphocholine level showed an increase (p<0.01) at the 6th month. The levels of acetate, acetone (p<0.05 for both) and creatine (p<0.01) decreased at the 6th month as compared to day 3 of lactation in both groups. However, the levels of oligosaccharides were similar between groups and also similar at day 3 and at the 6th month of lactation.

CONCLUSION

Our data indicates differential levels of metabolites in the milk of women with PE. Future studies are required to investigate the associations between milk components and infant growth and development.

Multi Organ Dysfunction in Term Neonates with Perinatal Asphyxia

Introduction: Multiorgan dysfunction (MOD) is one of the four consensus based criteria for the diagnosis of intrapartum asphyxia. The theoretical concept behind MOD is the diving reflex -conservation of blood flow to vital organs at the cost of non-vital organs. The objective of this study was to assess the patterns of involvement of each major organ/system in term asphyxiated neonates.Material and Methods: This was a hospital based prospective study. Sixty term neonates who had suffered perinatal asphyxia were assessed for central nervous system, kidney, cardiovascular system, gastrointestinal system and liver dysfunction. Results: Out of 60 eligible neonates, 57 (95%) had evidence of at least one organ dysfunction. Cardiovascular system involvement (95%) was most common, followed by renal system (37%), hepatic system (22%), central nervous system and hematological system (20% each) and finally, gastrointestinal tract (8%).Conclusion: MOD is frequently associated with perinatal asphyxia with cardiovascular system being the most commonly affected.J Nepal Paediatr Soc 2015;35(3):307-311.

Endoscopic management of post-liver transplant billiary complications: A prospective study from tertiary centre in India

BACKGROUND

Liver transplantation has become common in India over the last decade and biliary strictures after the procedure cause a significant morbidity. Endoscopic retrograde cholangiopancreatography (ERCP) is a safe and effective treatment modality for post-transplant biliary strictures so we decided to evaluate prospectively the outcomes of endoscopic treatment in post-living donor liver transplantation (LDLT) biliary strictures.

METHODS

We studied ten consecutive patients who had developed biliary strictures (out of 312 who had undergone liver transplantation between June 2009 and June 2013) and had been referred to the Department of Gastroenterology for management. All patients underwent liver function tests, ultrasound of the abdomen, magnetic resonance cholangiography and liver biopsy, if this was indicated.

RESULTS

Of these 312 patients who underwent liver transplantation, 305 had living donors (LDLT) and 7 deceased donors (DDLT). Ten patients in the LDLT group (3.3%) developed biliary strictures. There were seven males and three females who had median age of 52 years (range 4-60 years). The biliary anastomosis was duct-to-duct in all patients with one patient having an additional duct-to-jejunum anastomosis. The mode of presentation was cholangitis in four patients (40%), asymptomatic elevation of liver enzymes in four (40%) and jaundice in two patients (20%). The median time from transplantation to the detection of the stricture was 12 months (2-42.5 months). ERCP was attempted as initial therapy in all patients: seven were managed entirely by endoscopic therapy, and three required a combined percutaneous and endoscopic approach. Cholangiography demonstrated anastomotic stricture in all patients. A total of 32 sessions of ERCP were done with mean of 3.2 (2-5) endoscopic sessions and 3.4 (1-6) stents required to resolve the stricture. The median time from the first intervention to stricture resolution was 4 months (range 2-12 months). In four patients, the stents were removed after one session and in two patients each after two, three and four sessions. In six patients more than one stent was placed and all of them required dilatation of stricture. Seven patients completed treatment and are off stents at a median follow up period of 9.5 months (7-11 months). Two patients developed recurrence of their stricture after 7.5 months. Both had long strictures and required a combined endoscopic and percutaneous approach. There was one mortality due to sepsis secondary to cholangitis.

CONCLUSIONS

Post-LDLT biliary strictures can be successfully treated with ERCP, and most patients remain well on follow up (median 9.5 months). A combined endoscopic and percutaneous approach is useful when ERCP alone fails.

Functional Neonatal Echocardiography: Indian Experience

INTRODUCTION

Functional echocardiography, as opposed to echocardiography as performed by the cardiologist, is the bedside utilization of cardiac ultrasound to take after functional and haemodynamic changes longitudinally. Information reflecting cardiovascular capacity and systemic and pulmonary blood flow in sick preterm and term neonates can be observed utilizing this strategy. Information is lacking on its use in neonatal units in India.

AIM

To characterize the impact of Functional neonatal echocardiography (FnECHO) programme on decision making in a tertiary care centre in India by evaluating its frequency of use, patient characteristics, and indications.

MATERIALS AND METHODS

Prospective observational study of neonates in a tertiary Neonatal Intensive Care Unit (NICU) in Pune (India) from February 2014 to January 2015. All the neonates undergoing FnECHO during this 12 month period based on clinical findings were included in the study. Data extracted from the review of the clinical notes included gestational age, birth-weight, mode of delivery, Apgar scores, details of respiratory and cardiovascular support, timing of FnECHO and any other clinical diagnosis. The findings of echocardiography were recorded and correlated with the clinical and other laboratory or X-ray findings. If these findings indicated a change in management, it was instituted.

RESULTS

A total of 348 echocardiographic studies were performed in 187 neonates (mean 1.86; SD 2.02). The most frequent indication was Patent Ductus Arteriosus (PDA) assessment (n= 174, 50%), followed by haemodynamic instability (n=43, 12.36%). The results of FnECHO modified treatment in 148 cases (42.50%) in the form of addition and/or change in the treatment or avoidance of unnecessary intervention.

CONCLUSION

FnECHO is frequently used in the NICU setting and may be a useful tool to guide treatment. PDA assessment and haemodynamic instability are the most frequent indications. To validate its usefulness, well co-ordinated large prospective studies are needed.

Thymoma in a 14 Month Female with Mild Pure Red Cell Aplasia
