RESUMO

The abuse and misuse of antibiotics is one of the main drivers of antimicrobial resistance (AMR). Globally, AMR in food-producing animals is a significant public health concern. This study, therefore, assessed the knowledge, attitudes, and practices related to antibiotic usage (AMU) and AMR among poultry farmers in Nepal. We conducted a cross-sectional survey of 605 poultry farmers from six districts of Nepal from May to June 2022 to assess the status of knowledge, attitude, as well as practices toward prudent antibiotic usage (AMU) and AMR. The majority of the participants in our study were from the Chitwan district (31.6%; n = 191/605), aged 30-44 (54.2%; n = 328/605), males (70.4%; n = 426/605), and farmers with a higher secondary (28.76%; n = 174/605) level of education. The tetracyclines (28%, n = 228/828), aminoglycosides (23%, n = 188/828), and fluoroquinolones (15%, n = 126/828) were the most used antibiotics classes among poultry farmers. Although 87.8% (n = 531/605) of poultry farmers used antibiotics, 49.8% (n = 301/605) of them were aware of AMR, and 55.7% (n = 337/605) knew that the misuse of antimicrobials could affect human and environmental health. There were significant differences in the knowledge, attitude, and practices toward prudent AMU and AMR among farmers who reared different birds. The mean knowledge, attitude, and practice score of the respondents were 7.81 ± 3.26, 5.8 ± 2.32, and 7.59 ± 3.38 when measured on a scale of 12, 10, and 15, respectively. Based on a cut-off of 75% of the maximum score, 49.4% (n = 299/605), 62.8% (n = 380/605), and 12.73% (n = 77/605) of the respondents had good knowledge, attitude, and practices toward prudent AMU and AMR, respectively. The multivariable logistic regression analyses revealed that the positive predictors of good knowledge and attitude were male gender, higher level of education, district, and the types of birds (layers). Similarly, those of the male gender (OR: 3.36; 95% CI: 1.38-8.20; p = 0.008) and those that rear layers (OR: 4.63; 95% CI: 1.75-12.25; p = 0.003) were more likely to practice prudent usage of antimicrobials. The findings of this study show poor practice toward prudent antibiotic usage despite good knowledge of AMR. This study provides essential baseline data on the knowledge, attitudes, and practices of poultry farmers in Nepal and offers valuable insights that could help in the design of interventions and policies aimed at addressing illicit AMU and AMR in poultry in Nepal.

RESUMO

Environmental pollution is a growing threat to wildlife health and biodiversity. The relationship between marine mammals and pollutants is, however, complex and as new chemicals are introduced to ecosystems alongside concomitant, interacting threats such as climate change and habitat degradation, the cumulative impact of these stressors to wildlife continues to expand. Understanding the health of wildlife populations requires a holistic approach to identify potential threatening processes. In the context of environmental pollution in little studied wildlife species, it is important to catalogue the current exposome to develop effective biomonitoring programs that can support diagnosis of health impacts and management and mitigation of pollution. In New South Wales, Australia, the New Zealand fur seal (Arctocephalus forsteri) is a resident species experiencing population growth following devastating historic hunting practices. This study presents a retrospective investigation into the exposure of New Zealand fur seals to a range of synthetic organic compounds and essential and non-essential trace elements. Liver tissue from 28 seals were broadly analyzed to assess concentrations of organochlorine and organophosphate pesticides, polychlorinated biphenyls, per- and polyfluoroalkyl substances, and essential and non-essential trace elements. In addition to contributing extensive pollution baseline data for the species, the work explores the influence of sex, age, and body condition on accumulation patterns. Further, based on these findings, it is recommended that a minimum of 11 juvenile male New Zealand fur seals are sampled and analyzed annually in order to maintain a holistic biomonitoring approach for this population.

RESUMO

BACKGROUND Reversible cerebral vasoconstriction syndrome (RCVS) is a disorder characterized by recurrent thunderclap headaches and reversible cerebral vasoconstriction. CASE REPORT Herein, we present the case of a man in his forties with a disease entity related to RCVS accompanied by vasospasm of the extracerebral blood vessels throughout the body. The patient presented to the Emergency Department with a severe headache and epigastric pain. Initially receiving a misdiagnosis of functional pain, he continued to experience severe recurrent headaches, most often after urinating or defecating and was referred to our department. Suspecting RCVS, we performed magnetic resonance angiography, which revealed beaded irregularity in the right anterior cerebral and V4 vertebral arteries. The patient also had epigastric pain that coincided with each headache. Electrocardiography revealed pronounced ST-segment elevation in leads I and aVL and inverted T wave in lead III, while abdominal computed tomography angiography showed narrowing of the colic arteries. We named this disease "reversible systemic vasoconstriction syndrome" (RSVS) as a potential suggested terminology for the future. CONCLUSIONS RSVS is a clinical syndrome characterized by thunderclap headaches and simultaneous unbearable pain in extracerebral organs. To the best of our knowledge, this is the first case report of RCVS with coronary and colic artery vasospasm. We need to take great care of patients with chest or abdominal pain accompanied by recurrent thunderclap headaches, since they can be misdiagnosed with functional or psychogenic disorders.

RESUMO

Gastric subepithelial lesions (SEL) are usually found incidentally during esophagogastroduodenoscopy. Most gastric SELs are benign lesions, such as leiomyoma and pancreatic rests. However, neoplastic lesions including neuroendocrine tumors, gastrointestinal stromal tumors, and certain types of gastric adenocarcinoma (GA), such as the recently WHO-classified fundic gland type adenocarcinoma, may be found. The lack of simple and established diagnostic methods for SEL remains a clinical challenge. Standard biopsy is suboptimal for diagnosis due to the subepithelial location of lesions and is therefore often omitted. Furthermore, guideline-based algorithmic approaches for diagnosing SEL also differ between Japan and the USA. In this case series, we describe three cases of gastric SEL that were subsequently diagnosed as GA. Case 1 was a fundic gland type (chief cell predominant type) adenocarcinoma; Case 2 was a poorly differentiated GA; Case 3 was an advanced GA, found after 4 serial years of endoscopic follow-up for SEL. While standard biopsy led to successful diagnosis in the first 2 cases, no standard biopsy was performed during surveillance in Case 3, making its diagnostic effectiveness unclear. The third case highlights the importance of longitudinal observation for endoscopic mucosal alterations that may suggest certain types of GA. Clinicians should be aware that standard biopsy may play an important role in the evaluation of malignant gastric SEL-like lesions. It is crucial to remain vigilant for surface changes in SEL and not to summarily omit standard biopsy.

RESUMO

AIM: The North Queensland region of Australia has a high incidence of pediatric thoracic empyema (pTE). We describe the management of empyema at the Townsville University Hospital which is the regional referral center for these children. The impact of a newly developed institutional guideline is also discussed. METHODS: This retrospective audit included children under the age of 16 years treated for empyema between 1 Jan 2007 and 31 December 2018. Demographic and management-related variables were correlated to outcomes. A local guideline was introduced at the beginning of 2017 and patient outcomes characteristics pre, and post introduction of this guideline are compared. RESULTS: There were 153 children with pTE (123 before and 30 after the introduction of a local guideline). Nonsurgical management was associated with a higher treatment failure rate. Median length of stay (LOS) was 11.8 (IQR 9.3-16) days. Longer hospital LOS was associated with younger age (r2 -0.16, P = 0.04), Aboriginal and/or Torres Strait (ATSI) ancestry (13.8 vs. 10.5 days, P = 0.002) and concomitant respiratory viral infections (14.4 vs. 10.9 days, P = 0.003). The introduction of local guideline was associated with significant decrease in the use of empirical chest CT scans (54.4% before vs. 6.7% after, P < 0.001) and duration of intravenous antibiotics (14 days before vs. 10 days after, P = 0.02). There was no significant change in the hospital LOS (12.1 days pre and 11.7 post, P = 0.8). CONCLUSIONS: Younger age, concomitant viral respiratory infections and ATSI ancestry were identified as potential risk factors for increase LOS. Hospital LOS following the adoption of an institutional guideline was unchanged. However, such a guideline may identify populations at risk for an unfavorable course and avoid unnecessary antibiotic treatment and radiation exposure.

RESUMO

Vaccination is the most effective preventive measure of COVID-19 available at present, but its success depends on the global accessibility of vaccines and the willingness of people to be vaccinated. As the vaccination rollouts are increasing worldwide, it is important to assess public perception and willingness towards vaccination, so that the aim of mass vaccination will be successful. This study aimed to understand public perception towards COVID-19 vaccines and their willingness to get vaccinated in Nepal. This cross-sectional online survey was conducted among 1196 residents of Nepal in August 2021; most of the participants of this online survey were young adults (18-47 years) with university-level education. A total of 64.5% (771/1196) of the participants perceived COVID-19 vaccines to be safe and risk-free, while 68.6% (820/1196) agreed that vaccination would be efficient in the fight against this pandemic. Most of the participants (841/1196, 70.3%) disagreed that people are getting COVID-19 vaccines easily in Nepal, while they agree with the prioritization of older adults and healthcare workers for vaccination. A total of 61.1% (731/1196) of the participants had received at least one dose of the vaccine. Among the unvaccinated, 93.3% (434/465) were willing to get vaccinated when their turn came. The higher confidence of younger adults in vaccines and the vaccination process is encouraging, as that can help educate others who are hesitant or are not positive towards the idea of receiving vaccines. Dissemination of correct and current information, acquisition of enough doses of vaccines, and equitable distribution of vaccines will be required to achieve successful completion of the COVID-19 vaccination campaign in Nepal.

RESUMO

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are autoimmune mediated diseases triggered by group A streptococcal (GAS) infections. Molecular mimicry between GAS M-proteins and host tissue proteins has been proposed as the mechanism that initiates autoreactive immune responses in ARF/RHD. However, the individual role of antibodies and T-cells specific for GAS M-proteins in the pathogenesis of autoimmune carditis remains under-explored. The current study investigated the role of antibodies and T-cells in the development of carditis in the Lewis rat autoimmune valvultis (RAV) model by transferring serum and/or splenic T-cells from rats previously injected with GAS recombinant M5 protein. Here we report that serum antibodies alone and serum plus in vitro expanded rM5-specific T-cells from hyperimmune rats were capable of transferring carditis to naïve syngeneic animals. Moreover, the rats that received combined serum and T-cells developed more severe carditis. Recipient rats developed mitral valvulitis and myocarditis and showed prolongation of P-R intervals in electrocardiography. GAS M5 protein-specific IgG reactivity and T-cell recall response were also demonstrated in recipient rats indicating long-term persistence of antibodies and T-cells following transfer. The results suggest that both anti-GAS M5 antibodies and T-cells have differential propensity to induce autoimmune mediated carditis in syngeneic rats following transfer. The results highlight that antibodies and effector T-cells generated by GAS M protein injection can also independently home into cardiac tissue to cross-react with tissue proteins causing autoimmune mediated immunopathology.

RESUMO

AIM: The Townsville Hospital and Health Service is the regional referral centre for children in the north of Queensland. Aboriginal and Torres Strait Islander (ATSI) people make up 7-10% of the population. Increasing numbers of children with paediatric thoracic empyema (pTE) are being referred to Townsville Hospital and Health Service for management. This study aims to describe the incidence rates, epidemiology, microbiology and trends of this disease in North Queensland over a 10-year period. METHODS: A retrospective chart review of all children (1 month to 16 years), admitted in the years 2007-2016, with community-acquired pTE was conducted. International Classification of Diseases codes were used to identify the patients. Epidemiological and microbiological data were extracted from records. RESULTS: Of the 123 cases identified, incidence rates per 100 000 were 8.5 (95% confidence interval (CI) 8.4-8.6) in all children and much higher at 19.8 (95% CI: 19.5-21.9) in ATSI children. The under 5 years age group had the highest rate (24.5; 95% CI: 24.4-24.6). There was a progressive rise in incidence during the 10-year period, with the highest incidence of 15.2 (95% CI: 15.1-15.2) occurring in 2016. A pathogen was isolated in 76% of cases. Non-multi-resistant methicillin-resistant Staphylococcus aureus was the most common pathogen isolated in 22 of 64 ATSI children (34%), while Streptococcus pneumoniae was the most common pathogen isolated in 27 of 59 non-ATSI children (46%). CONCLUSIONS: A high and increasing incidence of pTE in North Queensland is being observed. ATSI children have higher incidence rates and are more likely to have non-multi-resistant methicillin-resistant Staphylococcus aureus as a causative agent.

RESUMO

Background & objectives: Oxidative stress, lifestyle factors as also exposure to certain environmental factors are known to affect the fertility status in human beings. The aim of this study was to evaluate the role of OS and lifestyle and environmental factors affecting IVF outcome. Methods: A total of 253 couples were included, and biological samples such as blood, follicular fluid (FF), cumulus cells and semen were collected. Relevant biochemical parameters and metals namely lead (Pb), cadmium (Cd), copper (Cu) and zinc (Zn) were determined in the biological samples. ß-human chorionic gonadotropin levels ≥100 IU/l were considered to predict viable pregnancy on the 15th day of embryo transfer (ET). Results: The mean body mass index (BMI) was significantly lower in females with positive IVF outcome compared to those with negative outcome. Couples residing in the residential area showed more percentage of positive IVF outcomes as compared to couples residing in industrial/agricultural area. FF Zn level was significantly higher (P<0.001) among the females' participants who have undergone ET as compared to those who have not undergone ET. FF MDA and serum Cu levels were significantly higher (P<0.05) in the female participants with negative IVF outcome as compared to positive IVF outcome. Logistic regression revealed that maternal BMI (P=0.034) and FF MDA level (P=0.047) were significantly associated with the IVF outcome. Interpretation & conclusions: The success rate of IVF was about 31.8 per cent, and BMI was significantly lower in females with positive outcome. The higher levels of MDA in FF and SP might have a negative impact on IVF outcome, higher Zn level in SP, FF and serum might have a positive role in embryo transfer as well as IVF outcome. The role of stress management and nutrition supplementation during the IVF treatment may be explored.

RESUMO

Arsenic (As) is an abundant toxicant present in groundwater and soil in various parts of the world including eastern part of India. The epidemiological studies have shown that arsenic exposure is linked to developmental defects and miscarriage. Placenta is known to utilize vasculogenesis to develop its vasculature circulation. The effects of four different doses of sodium meta-arsenite (0, 10, 20, 75, and 150 ppm) were assessed on the vascular structure using two different in vivo models, i.e., Matrigel and chorioallantoic membrane (CAM) assay. For the Matrigel assay, mice were exposed to different doses of arsenic through drinking water for 1 month. Placenta and Matrigel plug (which was inserted on gestational day (GD 0.5)) were removed on GD 14. Similar arsenic concentration was used in CAM assay to observe the effect of vessel development in hen's eggs. The CAM assay outcome evaluated by Angiosys software showed that arsenic exposure reduced the total and mean tubule length in all the arsenic-treated groups. The percentage tubule inhibition was declined significantly in 20, 75, and 150 ppm arsenic-treated groups as evaluated by ImageJ software. Analysis of the CAM outcome by both the image analysis software indicated the adverse effect of arsenic on the tubules. Further, a significant higher blood vessel density in 10 ppm and lower vessel density in 20, 75, and 150 ppm arsenic-exposed mice were also observed in Matrigel plug assay. The placental hypertrophy and dysplasia especially in the labyrinth zone (vasculature) were noted in placenta of arsenic-treated mice. The study indicated that higher arsenic exposures inhibited the angiogenesis which was dose-dependent in both CAM and Matrigel assay and altered structural morphology of placenta. However, no inhibition of blood vessels was noted at lower, i.e., 10 ppm of arsenic-treated group.

RESUMO

A method based on pressurized fluid extraction (PFE) was developed for measuring microplastics in environmental samples. This method can address some limitations of the current microplastic methods and provide laboratories with a simple analytical method for quantifying common microplastics in a range of environmental samples. The method was initially developed by recovering 101% to 111% of spiked plastics on glass beads and was then applied to a composted municipal waste sample with spike recoveries ranging from 85% to 94%. The results from municipal waste samples and soil samples collected from an industrial area demonstrated that the method is a promising alternative for determining the concentration and identity of microplastics in environmental samples.

RESUMO

Phthalate compounds are widely used industrial chemicals; when incorporated into polyvinyl chloride, they are not covalently bound and released into the surrounding media. Some of them have estrogenic potential in vitro but data on in vivo studies are scanty. For the 3-day uterotrophic assay, di-n-butyl phthalate (DBP;10 and 100 mg/kg), butyl benzyl phthalate (BBP; 20 and 200 mg/kg), and diethylstilbestrol (DES, 40 µg/kg, positive control) were administered orally to immature female rats for three consecutive days from postnatal day (PND) 21. For the 20-day pubertal onset assay, DBP (10 and 20 mg/kg), BBP (20 and 200 mg/kg), and DES (6 µg/kg) were administered orally from PND 21 daily for 20 days. In the uterotrophic assay, in groups treated with higher dose of DBP and BBP, the uterine wet weight significantly decreased in the higher dose, and there were minor variations in the ovary wet weight, while the wet weight of these organs increased significantly in DES-treated group. In the 20-day pubertal assay, the weight of uterus and ovary declined significantly and changes in vaginal weight were nonsignificant in DBP- and BBP-treated groups. However, in DES-treated group nonsignificant elevation in vagina weight was observed. All the DES-treated animals showed the vaginal opening (VO) on day 26.17 ± 0.16. However, VO was not observed in any of the animals in control, vehicle control, BBP-, and DBP-treated groups up to PND 42, except in one animal each in vehicle control and DBP (100 mg/kg)-treated groups. The data indicated that both DBP and BBP were unable to induce elevation in the uterine and ovarian weight. While DES treatment can accelerate the growth of uterus and ovary and alter the onset of puberty and estrous cyclicity in prepubertal rats. These suggest that these compounds may not have estrogenic potential in vivo.

RESUMO

Endemic fluorosis was detected in 31 villages in the Dhar district of Madhya Pradesh, Central India. Out of the 109 drinking water sources that were analyzed, about 67 % were found to contain high concentration of fluoride above the permissible level of 1.0 mg/l. Dental fluorosis among the primary school children in the age between 8 and 15 served as primary indicator for fluoride intoxication among the children. Urinary fluoride levels among the adults were found to be correlated with drinking water fluoride in 10 villages affected by fluoride. Intervention in the form of alternate safe water supply in five villages showed significant reduction in the urinary fluoride concentration when compared to the control village. Urinary fluoride serves as an excellent marker for assessing the effectiveness of intervention program in the fluoride-affected villages.

RESUMO

OBJECTIVES: To determine the incidence, risk factors and impact of ventilator-associated pneumonia (VAP) in a mixed tertiary paediatric intensive care unit. DESIGN: Prospective observational study. METHODS: Patients in the intensive care unit who were mechanically ventilated for more than 48 hours were assessed daily, according to criteria for a diagnosis of VAP. Potential risk factors for VAP, if present, were documented. RESULTS: Of 692 invasively ventilated patients, 269 (38.9%) were ventilated for > 48 hours and met no exclusion criteria. Eighteen (6.7%) patients had episodes of VAP, and the VAP incidence density was 7.02 per 1000 intubation days. The mean admission Paediatric Index of Mortality 2 risk of death was similar in patients with and without VAP (0.084 v 0.056; P =0.8). Patients with VAP (compared with patients without VAP) had a longer median duration of ICU stay, (19.35 v 7.35 days; P < 0.001), duration of ventilation (11.99 v 4.92 days; P=0.024) and duration of hospital stay (35.5 v 20 days; P < 0.001). Univariate analysis showed that reintubation, absence of tube feeding and absence of stress ulcer prophylaxis were risk factors for VAP. While backward selection removed reintubation as a positive predictor during multivariate analysis, tube feeds (hazard ratio (HR), 0.27; 95% CI, 0.09-0.85; P = 0.02) and stress ulcer prophylaxis (HR, 0.29; 95% CI, 0.11-0.76; P = 0.01) were independently associated with reduced VAP incidence. CONCLUSIONS: VAP in children is associated with significant morbidity and increased length of hospital stay. Enteral feeding and stress ulcer prophylaxis while intubated are associated with lower VAP hazards.

RESUMO

PURPOSE: To redress the paucity of studies evaluating non-invasive respiratory support in bronchiolitis patients. METHODS: Following ethics committee approval, the clinical database of a tertiary 23-bed paediatric intensive care unit (PICU) was reviewed for bronchiolitis admissions from January 2000 to December 2009. Length of stay (LOS), ventilatory requirements and risk factors, including prematurity, respiratory syncytial virus (RSV) status, chronic lung, neuromuscular, immune and congenital heart disease, were analysed. RESULTS: Of 8,288 admissions, 520 (6.27 %) had bronchiolitis with 343 (65.9 %) having RSV. Median (±SD) age and LOS were 2.78 months and 2.68 (±4.32) days. One (0.2 %) patient died. Assisted ventilation was required for 399 (76.7 %) patients. A total of 114 (28.6 %) patients were intubated directly and 285 (71.4 %) had a trial of non-invasive ventilation (NIV). Significant increase in the use of NIV was seen (2.8 %/year) with decline in intubation rates (1.9 %/ year) (p = 0.002). Of NIV patients, 237 (83.2 %) needed only NIV and 48 (16.8 %) failed and therefore needed intubation. The median LOS was shorter in those who succeeded NIV (2.38 ± 2.43 days) compared to those with invasive ventilation (5.19 ± 6.34 days) and those who failed NIV (8.41 ± 3.44 days). Presence of a risk factor increased the chances of failing NIV from 6 to 10 %. CONCLUSION: NIV was successful in the vast majority of patients, particularly in those without risk factors and halved the LOS in intensive care. Failure of NIV was associated with increased duration of invasive ventilation and PICU LOS. A prospective study comparing different techniques of NIV will be helpful in defining the risks of failure of NIV.

RESUMO

UNLABELLED: Chewing mixture containing areca nut and tobacco is believed to be associated with oral cancer. Habit of chewing such mixture is prevalent among South Asian countries. This study aimed to evaluate the genotoxic effect of areca nut and tobacco on human lymphocytes. Peripheral blood from 107 subjects (nonchewers, 48; chewers, 59, including 20 subjects with oral submucous fibrosis [OSMF]) analyzed by cytokinesis-block micronucleus (CBMN) and alkaline comet assay. Nuclear anomalies, namely, binucleated cells with micronuclei (BN MN), total MN, nucleoplasmic bridge, and nuclear buds were higher in chewers whereas elevation in BN MN and total MN were significant among subjects with OSMF than nonchewers. DNA damage assessed by comet assay showed increased percentage of Tail DNA, Tail moment, and Olive tail moment among chewers as well as OSMF subjects. Significant positive correlation was observed between induction of CBMN and consumption of quids per day (r = .280, P = .033). RESULTS: suggested cytotoxic and genotoxic potential of mixture containing areca nut and tobacco.

RESUMO

OBJECTIVES: To determine seminal antioxidant capacity, oxidative stress markers, and their association with semen quality as oxidative stress is considered to be a major etiological factor in male infertility. SUBJECTS AND METHODS: Semen samples were obtained from 138 men and categorized on the basis of sperm count, motility, and morphology. Seminal oxidative and antioxidant markers are as follows: lipid peroxidation (LPO), protein carbonyls (PC), superoxide dismutase (SOD), catalase (CAT), thiols, and ascorbic acid were determined. RESULTS: Sperm count significantly correlated positively with progressive sperm motility and normal morphology. Sperm count and normal morphology showed significant negative correlation with LPO and PC. Sperm count and progressive motility showed significant positive relationship with SOD. The SOD, CAT, and thiols positively whereas LPO and PC negatively associated with elevated sperm count. CONCLUSION: Insufficient antioxidant enzymes and increased oxidative stress may attribute to the risk of declining semen quality and hence protective role for antioxidant enzymes against the oxidative damage cannot be ruled out.

RESUMO

AIMS: To determine the prevalence of celiac disease (CD) in siblings of patients with this disease in Punjab, where wheat is the staple diet. METHODS: Families of 80 patients with CD diagnosed as per modified ESPGAN criteria were offered family screening. Their siblings aged 2-15 years were tested for serum IgA anti-tissue transglutaminase antibody (anti-tTG) antibody. Those with positive or borderline test and some of those with negative test underwent endoscopic duodenal biopsy. Siblings with characteristics histological findings and showing improvement on follow-up were labeled as having celiac disease. RESULTS: Of the 63 siblings of 48 index cases studied, 15 tested positive for anti-tTG; of these 13 had celiac disease. Three tested borderline for anti-tTG; none of them had CD. Of the 45 anti-tTG-negative subjects, two agreed to undergo biopsy; one of these had features of CD. Overall, 14 of 63 (22%) siblings had CD, including 8 who had no symptoms suggestive of CD. CONCLUSIONS: CD is common among siblings of patients with CD in Punjab and may be asymptomatic.

RESUMO

This prospective study was carried out to evaluate the clinical and anthropometric profile of 71 children confirmed to have celiac disease on the basis of clinical features, duodenal biopsy and unequivocal improvement on gluten-free diet. Serological tests were performed in 35 cases. The patients were divided into three age groups <5 years, 5-10 years, and >10 years as per the age of presentation to the hospital. Mean age was 8.7 years with a slight female preponderance. Diarrhea was the commonest presentation in group I and failure to thrive in group III. All patients in group III, had weight for age (w/a) <3rd percentile and majority (83 per cent) had short stature, with delayed puberty in all. All children had significant improvement in symptoms and growth on gluten restriction. None of the patients had been suspected to have celiac disease before, which signifies that in spite of increasing incidence of celiac disease, this disease is grossly under-diagnosed in North India where wheat is the staple diet. It is essential to make an early diagnosis of celiac disease in children to prevent growth delay.
