Gastrointestinal and sensory manifestations, nutrition management, and energy-protein intake in hospitalized patients with COVID-19.

BACKGROUND: Gastrointestinal and sensory manifestations (GSMs) of coronavirus disease 2019 (COVID-19) may affect food intake, resulting in malnutrition and poor outcomes. We characterized the impact of GSMs and oral nutrition supplementation on energy-protein intake (EPI) and hospital discharge in adult patients with COVID-19. METHODS: Patients from two hospitals were enrolled (n = 357). We recorded the presence and type of GSM at admission, estimated energy requirements (EER) and the EPI based on regular food intake (plate diagram sheets) during hospital stays. Patients not achieving 60% of their EER from food over 2 consecutive days received oral nutrition supplementation (ONS) with a high-energy-protein oral drink. RESULTS: Most patients (63.6%) presented with GSMs at admission. Anorexia was the most common manifestation (44%). Patients with anorexia or more than one GSMs were more likely to not achieve 60% EER on the first day of follow-up and to require the ONS intervention (P ≤ 0.050). Prevalence of at least one GSM was higher in patients who did not achieve hospital discharge than in patients who achieved it (74.2% vs 54.6%, P = 0.038). The patients requiring ONS (26.9%) demonstrated good adherence to the intervention (79.3%), achieved their EER during 95.7% of the supplementation time, and presented with hospital discharge rates similar to patients not requiring ONS (92.2% vs 91.9%, respectively; P = 1.000). CONCLUSIONS: GSM were prevalent in COVID-19 and it impaired EER attendance and patient recovery. ONS was well-tolerated, aided EER attendance, and potentially facilitated hospital discharge.

Assessment of Alcohol Consumption and Anxiety as Predictors of Risk of Anorexia and Bulimia in Non-Clinicals Samples.

The objective of this study is to assess the effect of alcohol consumption, anxiety, and food restriction before and after consuming alcohol and body image on the risk of anorexia and bulimia in college students from Tijuana, Baja California, through predictive statistical models. A quantitative, descriptive, and cross-sectional design and a non-probabilistic sample of 526 college students from Tijuana, Baja California, México were used. Application of the scales (with acceptable psychometric properties) was conducted in classrooms. Through path analyses, four models were found with adequate indicators of goodness of fit: (1) risk of anorexia in women [Chi Square (X2) = 5.34, p = 0.376, Adjusted Determination Coefficient (R2)= 0.250]; (2) anorexia risk for men (X2 = 13.067, p = 0.192, R2 = 0.058); (3) risk of bulimia in women (X2 = 3.358, p = 0.645, R2 = 0.202); and bulimia risk for men (X2 = 14.256, p = 0.075, R2 = 0.284). The findings provide empirical evidence for the food and alcohol disturbance model.

Role that anorexia and weight loss play in patients with stage IV lung cancer.

OBJECTIVE: To evaluate the prevalence of anorexia and weight loss at diagnosis (pre-treatment), to identify the factors associated with pre-treatment weight loss, and to determine the prognostic role of anorexia and weight loss in the overall survival of patients with stage IV lung cancer. METHODS: This was a retrospective observational cohort study. The patients were stratified by the presence/absence of anorexia and of pre-treatment weight loss, which generated a measure composed of four categories, which were the independent variables. RESULTS: Among the 552 patients included in the study, anorexia and pre-treatment weight loss were present in 39.1% and 70.1%, respectively. After adjusting for age, male gender, and Karnofsky performance status, we found that anorexia and tumor size were significantly associated with pre-treatment weight loss. In a Cox multivariate analysis, adjusted for age, male gender and low Karnofsky performance status were found to be independent predictors of worse survival, as was concomitance of anorexia and weight loss. CONCLUSIONS: Anorexia and pre-treatment weight loss appear to be relevant problems in the follow-up of patients with advanced (stage IV) lung cancer Specific interventions are of crucial importance in individualized treatment plans, even within the context of palliative care.

RESUMO Objetivo: Avaliar a prevalência de anorexia e perda de peso ao diagnóstico (pré-tratamento), os fatores associados à perda de peso pré-tratamento e o papel prognóstico da anorexia e da perda de peso na sobrevida global de pacientes com câncer de pulmão em estádio IV. Métodos: Estudo de coorte retrospectivo observacional. Os pacientes foram estratificados, dependendo da presença/ausência de anorexia e da presença/ausência de perda de peso pré-tratamento, o que gerou uma medida composta de anorexia e perda de peso de quatro níveis, que foi a variável independente. Resultados: Entre os 552 pacientes incluídos no estudo, as prevalências de anorexia e de perda de peso pré-tratamento foram de 39,1% e 70,1%, respectivamente. Após ajustar para idade, sexo masculino e índice de Karnofsky, a presença de anorexia e o tamanho do tumor foram significativamente associados à perda de peso pré-tratamento. Na análise multivariada de Cox, após ajustar para a idade, as variáveis sexo masculino, presença concomitante de anorexia e perda de peso e índice de Karnofsky reduzido foram preditores independentes de pior probabilidade de sobrevida. Conclusões: O presente estudo demonstrou que a presença de anorexia e de perda de peso pré-tratamento são problemas relevantes no seguimento de pacientes com câncer de pulmão avançado (estádio IV). Intervenções específicas são de crucial importância no plano de assistência individualizada, mesmo dentro da proposta de cuidados paliativos.

Malnutrition associated with nutrition impact symptoms and localization of the disease: Results of a multicentric research on oncological nutrition.

BACKGROUND & AIMS: Malnutrition in cancer is an independent factor associated with negative clinical outcomes. The aim was to evaluate the prevalence and independent risk factors for malnutrition in hospitalized cancer patients using the Patient-Generated Subjective Global Assessment (PG-SGA). METHODS: We evaluated 4783 cancer patients, aged ≥20 years, in a hospital-based, multicenter, cross-sectional study. Patients were classified as well-nourished (PG-SGA Stage A), moderate/suspected malnutrition (PG-SGA Stage B), or severely malnourished (PG-SGA Stage C), and provided a score to define required nutritional interventions. Multivariate analysis was composed of the odds ratio (OR) estimated by ordinal polytomous logistic regression. RESULTS: 45.3% were classified as Stage B and 11.8% as Stage C. Moreover, 45.3% of the patients presented a need for nutritional intervention. The variables that presented the highest ORs for Stage B or Stage C were: problems with swallowing (OR 2.8, 95% confidence interval (CI) 2.2-3.4, p < 0.001), loss of appetite (OR 1.9, 95% CI 1.6-2.3, p < 0.001), vomiting (OR 1.8, 95% CI 1.5-2.3, p < 0.001), presence of more than 3 nutrition impact symptoms (OR 8.3, 95% CI 5.8-12, p < 0.001), and cancer site: lung (OR 4.6, 95% CI 3.2-6.6, p < 0.001), upper digestive cancer (OR 3.7, 95% CI 2.7-5.2, p < 0.001), and head and neck cancer (OR 3.7, 95% CI 2.7-5.2, p < 0.001). The score for Worksheet 4 on the PG-SGA had a higher association with malnutrition (OR 7.3, 95% CI 6.6-8.2, p < 0.001). CONCLUSIONS: Malnutrition is highly prevalent in cancer patients in Brazil, and is associated with nutritional impact symptoms, cancer site and age ≥65 years.

[Anorexia-cachexia frequency and its gastrointestinal symptoms association in paliative patients at the Instituto Nacional de Cancerología, México]. / Frecuencia de anorexia-caquexia y su asociación con síntomas gastrointestinales, en pacientes paliativos del Instituto Nacional de Cancerología, México.

BACKGROUND: Anorexia-cachexia is a frequent syndrome among cancer patients, specially in late stages: the global prevalence of para-neoplastic anorexia-cachexia ranges between 20-40% in the diagnostic stage and between 70-80% in the late stage of the disease. The co-existence of functional or structural digestive abnormalities is frequently observed among cancer patients; this is a consequence of the tumor growth and of those systemic phenomena related to metabolism, which are affected by the relationship tumor-host specific to anorexia- cachexia. OBJECTIVE: This study aimed at establishing the frequency of anorexia-cachexia, as well as its relationship to GI symptoms in the context of palliative care patients at the Instituto Nacional de Cancerología, México City. METHODS AND MATERIAL: Analytic cross-sectional study including 100 patients diagnosed with late-stage cancer, age range 18-80, and a Karnofsky score > 50, as well as an ECOG <2; patients with a bad general health status were not allowed in the study. After reviewing inclusion and exclusion criteria, participants fulfilled the FAACT questionnaire, as well as the EGS. Patients recruitment was carried out by the Instituto Nacional de Cancerología. Results and discussion: Results show that 61% (n=61)of the patients had anorexia-cachexia, and 39% (n=39)did not. 56% of the sample participants (n=34) were women, and 44% (n=27) were men. GI symptoms associated with anorexia-cachexia were: nausea (p= 0.0001), vomiting (p=0.004), early satiety (p=0.0005), dysgeusia(p=0.0005) and dysphagia (p=0.001). CONCLUSION: Anorexia and cachexia are among the most devastating and frequent symptoms in late-stage cancer patients and they are also associated with GI symptoms affecting the physical, psychosocial and existential aspects of the patient's life. Data from this research validate the importance of an early nutrition support in palliative patients so that they can achieve a better quality of life.

En los enfermos oncológicos es frecuente la coexistencia de alteraciones digestivas estructurales o funcionales, secundarias al crecimiento tumoral y a los fenómenos sistémicos de carácter metabólico, determinados por la interrelación tumor-huésped específicos de la anorexia-caquexia. Objetivo: El objetivo de este trabajo es conocer la frecuencia de anorexia-caquexia, y su asociación con síntomas gastrointestinales en pacientes en terreno paliativo del Instituto Nacional de Cancerología, Ciudad de México, atendidos en el servicio de Cuidados Paliativos. Material y métodos: Se realizó un estudio transversal analítico. Se incluyeron 100 pacientes con diagnóstico de cáncer avanzado, con un rango de edad de 18 y 80 años, y una puntuación de Karnofsky > 50, así como un ECOG.

Assessment of the reliability and consistency of the "malnutrition inflammation score" (MIS) in Mexican adults with chronic kidney disease for diagnosis of protein-energy wasting syndrome (PEW).

BACKGROUND: The protein-energy wasting syndrome (PEW) is a condition of malnutrition, inflammation, anorexia and wasting of body reserves resulting from inflammatory and non-inflammatory conditions in patients with chronic kidney disease (CKD).One way of assessing PEW, extensively described in the literature, is using the Malnutrition Inflammation Score (MIS). OBJECTIVE: To assess the reliability and consistency of MIS for diagnosis of PEW in Mexican adults with CKD on hemodialysis (HD). METHODS: Study of diagnostic tests. A sample of 45 adults with CKD on HD were analyzed during the period June-July 2014.The instrument was applied on 2 occasions; the test-retest reliability was calculated using the Intraclass Correlation Coefficient (ICC); the internal consistency of the questionnaire was analyzed using Cronbach's αcoefficient. A weighted Kappa test was used to estimate the validity of the instrument; the result was subsequently compared with the Bilbrey nutritional index (BNI). RESULTS: The reliability of the questionnaires, evaluated in the patient sample, was ICC=0.829.The agreement between MIS observations was considered adequate, k= 0.585 (p <0.001); when comparing it with BNI, a value of k = 0.114 was obtained (p <0.001).In order to estimate the tendency, a correlation test was performed. The r² correlation coefficient was 0.488 (P <0.001). CONCLUSION: MIS has adequate reliability and validity for diagnosing PEW in the population with chronic kidney disease on HD.

[Epidemiology and risk factors of eating disorder in adolescence: a review]. / La epidemiología y los factores de riesgo de los trastornos alimentarios en la adolescencia: una revisión.

INTRODUCTION: Currently, there is a higher occurrence of biopsychosocial diseases, especially eating disorders, involving different body systems and aspects related to the individual and their social relations. OBJECTIVE: Addressing current and relevant issues about the prevalence, incidence and risk factors for anorexia and bulimia nervosa in adolescence. METHODS: Search the databases: MEDLINE, SciELO and LILACS for studies published on the epidemiology and risk factors for eating disorders in adolescence. RESULTS: The highest incidence of anorexia and bulimia nervosa among girls in the middle and final phase of adolescence. Factors that increase the risk for the onset of eating disorders in adolescents are: genetics, body changes during puberty, the vulnerability of adolescents to the ideals of thinness, social pressures to be thin, body image dissatisfaction, restrictive diet, depression and low self-esteem. However, it is suggested that in different cultures, eating disorders may come from a number of conditions unrelated to compensatory behaviors or weight, but the shape of the body. CONCLUSIONS: Several factors determine the occurrence of anorexia and bulimia nervosa in adolescence, however, there is no consensus how these factors interact in this complex process, which indicates the need for further investigations.

Risk behaviors for eating disorders in Brazilian dancers.

This study investigated the frequency of risk behaviors for eating disorders and their association with anthropometric, demographic, and socioeconomic variables in Brazilian professional dancers. Portuguese-language versions of the Eating Attitudes Test and of the Bulimic Investigatory Test, Edinburgh (BITE) were applied to 39 female and 22 male dancers considered to be some of the best classical ballet performers in Brazil. Prevalence ratios (PR) and 95% confidence intervals (CI) were estimated. Risk behaviors for eating disorders were observed in 31% of the dancers. Those who had a percentage of body fat above (PR=4.04; 95% CI=1.42-11.47) or below (PR=3.57; 95% CI=1.04-12.24) what is considered normal for the profession, and those who lived alone (PR=3.13; 95% CI=1.16-8.48) presented higher risk for eating disorders. In conclusion, the frequency of risk behaviors for eating disorders among the Brazilian dancers was high, which seems to be associated with the physical requirements of the profession. Those who are outside the BF% expected for dancers and those who live alone are the groups most vulnerable to developing eating disorders, and thus are the ones which are most in need of receiving special attention in regard to the intervention measures.

Molecular and epidemiological investigations of cryptosporidiosis in Cuban children.

Molecular and epidemiological studies of Cryptosporidium infections amongst 28 Cuban children (aged 2-8 years) with diarrhoea are described. As few of the younger infected children but most of the older infected children had been breastfed, short-term protection from maternal antibodies passed to infants during breastfeeding may result in a lack of cryptosporidial infection in infancy. This protection of breastfeeding children may, however, result in such children developing less anti-Cryptosporidium immunity of their own (than their bottle-fed counterparts), so that, by school age, the children who had been breastfed are those most likely to be found infected. In the present study, in contrast with the observations made during a previous study of cryptosporidiosis in Cuban children, vomiting was rare (7%) whereas abdominal pain was common (57%). These differences in expression of symptoms between studies may be age-related. As seen in other studies from similar countries, including those of the Caribbean and Latin America, C. hominis was found to predominate, the results of the successful molecular analyses revealing 10 C. hominis infections but no C. parvum. Subgenotyping (at the gp60 locus) indicated that the C. hominis infections included a wide range of subtypes, with isolates from three subtype families (Ia, Ib and Id) being detected.

Trastornos de la conducta alimentaria en mujeres embarazadas controladas en atención primaria / Eating disorders in pregnant women controlled in primary care

Antecedentes: En relación al impacto de los trastornos de la conducta alimentaria (TCA) sobre el embarazo, la mayoría de la evidencia advierte sobre consecuencias negativas prenatales y postnatales para la madre y el feto. Objetivo: Determinar la presencia de comportamientos alimentarios anormales en gestantes controladas en atención primaria, y analizar descriptiva y comparativamente las pacientes con estas actitudes en relación con variables maternas, del embarazo, rasgos psicológicos y conductuales. Método: 141 pacientes embarazadas fueron encuestadas con el test de actitudes alimentarias (EAT-40) y el inventario de trastornos alimentarios (EDI), a los cuales se añadieron preguntas relativas al embarazo e historia de TCA. Resultados: 23,4 por ciento de las encuestadas obtuvieron puntajes en rango patológico de EAT-40, donde la historia previa de TCA emerge como un factor de riesgo importante para el desarrollo de un desorden alimentario en estas pacientes. Otras diferencias se observaron en los puntajes del EAT-40, el EDI y todas sus subescalas. Conclusión: La cifra alcanzada para conductas anormales de alimentación supera ampliamente a la planteada para TCA clínicos, los que además reflejan tendencia a la cronicidad aun en el embarazo. Se requieren estudios adicionales que orienten a los profesionales de salud en la prevención, detección y tratamiento de los TCA en el embarazo.

Background: According to the impact of eating disorders on pregnant women, most evidence shows negative pre and post natal consequences for the mother and the fetus. Objective: To determine the presence of abnormal eating behaviors in pregnant women controlled in primary care, and to describe and compare eating disordered patients in relation to the pregnancy, maternal, psychological and behavioral characteristics. Method: The Eating Attitudes Test (EAT-40), the Eating Disorders Inventory (EDI) and a questionnaire about demographic and pregnancy data and previous history of eating disorders were administered to 141 pregnant women. Results: 23.4 percent of the polled women scored within the pathological range of EAT-40, in whom the prior history of eating disorders emerged as the most important factor of risk to develop an eating disorder in these patients. Furthermore, considerable differences were seen in the average of EAT-40 scores and in the EDI and its all subscales. Conclusion: The percentage of pregnant women who displayed abnormal eating behaviors exceeds the rate described in literature for clinical eating disorders. Besides, it reflect tendency to be a chronic disease even in pregnancy. Additional studies are required to help health personnel to prevent, detect and treat women with eating disorders in pregnancy.

Serum leptin levels in Ache Amerindian females with normal adiposity are not significantly different from American anorexia nervosa patients.

Serum leptin, a polypeptide hormone secreted primarily by adipocytes, is a reflection of somatic fat availability in humans and other vertebrates. Among Ache Amerindians, leptin levels are very low in contrast to other populations, despite comparable adiposity with individuals exhibiting much higher leptin levels. In order to gain a greater understanding of these differences, leptin levels were compared between Ache Amerindian females (n = 12, mean age = 32.2 +/- 14.0 SD), American females diagnosed with anorexia nervosa (n = 22, mean age = 23.0 +/- 4.0), and non-anorectic American controls (n = 23, mean age = 23.0 +/- 4.0). Ache leptin (5.6 +/- 3.2 ng/ml) was not significantly different from anorectic patients (5.6 +/- 3.7 ng/ml; P > 0.98) despite greater adiposity (Ache 33.3% +/- 4.4% vs. anorectic 7.0% +/- 2.0%; P < 0.0001). Ache adiposity was also higher than American controls (leptin 19.1 +/- 8.1 ng/ml; fat 28% +/- 5.0%; P < 0.004) underscoring the uniqueness of Ache leptin profiles. This suggests a greater range of population variation in leptin physiology than previously suspected and intimates the potential role of chronic environmental conditions.

[Tolerance to administration of massive doses of vitamin A associated to mass immunization of children in Northeast Brazil]. / Tolerância à aplicação de megadoses de vitamina A associada à vacinação em crianças no Nordeste do Brasil.

A follow-up study was carried out in two localities in the semi-arid region of the State of Bahia, Northeast Brazil, with the aim of identifying the occurrence and nature of possible acute side effects subsequent to vitamin A megadose supplement given together with mass immunization in children 6-59 months old. The sample consisted of 852 children, 416 from the county of Teofilandia who received vitamin A together with vaccines and 436 from Santa Barbara, who received only vaccine. In the 24 hours before immunization, children from both groups had similar incidences of diarrhea, fever, and vomiting. Anorexia was more prevalent in Teofilandia and remained so throughout the study period. The results suggest that acute side effects like diarrhea, vomiting, fever, or anorexia were not associated with the vitamin A dosage given with mass OPV, DPT, and measles immunization.

Anorexia y bulimia nerviosa. Aspectos odontológicos / Anorexia and nervous bulimia. Dental aspects

Estos trastornos del comportamiento alimentario se escapan cada vez con mayor frecuencia al examen clínico dental, por el aumento en el número de casos que en la actualidad se presentan, es imperativo el conocimiento y la capacitación en cuanto a cómo este tipo de desórdenes alimentarios de naturaleza psiquiátrica inciden y modifican la práctica dental rutinaria desde aspectos psicológicos y conductuales del paciente, hasta manifestaciones clínicas específicas que suponen un reacomodo de las prioridades preventivas y terapéuticas en odontología. Por la temprana edad promedio en la que estos pacientes acuden a la condulta, el dentista juega un rol importante en la detección y diagnóstico oportuno de esto padecimientos que usualmente son manejados tardíamente en las clínicas psiquiátricas varios años después. En este trabajo se presenta una revisión bibliográfica general de estos dos trastornos, exponiendo aspectos generales del síndrome y relativos a la repercusión que tienen en los dientes y demás tejidos bucales, como parte integral de estos trastornos y no como entidades aisladas, así como los recursos terapéuticos que existen para su manejo odontológico

Validity and epidemiology of reported poor appetite among Peruvian infants from a low-income, periurban community.

To assess the validity of maternal reports of poor infant appetite, these histories were compared with measured energy consumption on 1621 d of observation of 131 Peruvian infants in a low-income community. Mean (+/- SD) total energy intakes on days with reported anorexia were 338 +/- 88 kJ/kg body wt in infants 1-6 mo of age and 299 +/- 92 kJ/kg body wt in infants aged > 6 mo compared with 395 +/- 92 and 342 +/- 88 kJ/kg body wt in the respective age groups when appetites were reportedly normal (P < 0.001). Energy intake from non-breast-milk sources was more affected than energy from breast milk. The epidemiology of poor appetite was assessed in 153 infants who were monitored longitudinally during their first year of life. The prevalence of reported anorexia increased progressively from 22 to 317/1000 d of observation from < 1 to 11 mo of age. Infant age and the presence of fever, diarrhea, and respiratory illnesses were each associated negatively with the presence of reduced appetite. Poor appetite, rather than lack of food, may explain in part the low energy intakes by infants in this community.

PIP: In Huascar (a low-income, periurban community in eastern Lima), Peru, a study followed 131 low birth infants (2.5 kg) for one year to compare mothers' reports of poor appetite with dietary intake (1621 days of observation). Infants consumed lower energy intakes during days mothers reported anorexia than during days mothers reported a normal appetite (1-6 month olds, 338 vs. 395 kJ/kg body weight; 6 month olds, 299 vs. 342 kJ/kg body weight) (p 0.001). In fact, when the researchers controlled for age, body weight, and the presence of specific symptoms of illness, intraindividual total energy intakes were almost 15% less on days of reported anorexia. Energy intake from non-breast milk sources was about 25-35% less in both age groups on days of reported anorexia (p 0.01). The researchers examined longitudinal data on 153 infants who were monitored during their first year of life to determine the epidemiology of poor appetite. As the age of the infant increased so did the prevalence of reported anorexia (22-317/1000 days of observation from 1 to 11 months of age). Mothers reported anorexia on about 15% of the 48,057 days of observation. A significant positive association between anorexia and fever, severe diarrhea, and respiratory illness existed. These findings suggest that poor appetite, instead of insufficient food, may partially account for the low energy intakes by infants in Huascar.

Trastornos psicosomáticos pacientes que acuden a consulta externa de un hospital de niños / Psicosomatic upsets dune in the pediatric consult of the Robert Reid Cabral Hospital, Santo Domingo, Dominican Republic

Estudio prospectivo y analítico de los trastornos psicosomáticos en la consulta pediátrica del Hospital Robert Read Cabral, Santo Domingo, República Dominicana, de noviembre a diciembre, 1990. De 102 casos en total tratados en este lapso de tiempo se encontró que el sexo masculino fue el más afectado (55.0//), la mayoría estaba entre los 4-9 años de edad (60.0//). Fueron los trastornos psicosomáticos más frecuentes: enuresis (29.41//), cefalea (17.65//) y los dolores abdominales (9.8//). Los niveles socioeconómicos (de medio bajo a bajo en la casi totalidad de los casos) se han considerado de importancia causal entre los trastornos estudiados

Simultaneous administration of a diphtheria and tetanus toxoids and acellular pertussis vaccine with measles-mumps-rubella and oral poliovirus vaccines.

OBJECTIVE: To compare the safety and immunogenicity of Lederle Laboratories' (Pearl River, NY) diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine with diphtheria and tetanus toxoids and whole-cell pertussis (DTwP) vaccine when administered simultaneously with measles-mumps-rubella (MMR) vaccine and trivalent oral poliovirus (OPV) vaccine at 15 to 16 months of age. DESIGN: Randomized and double-blind. SETTING: Two general pediatric practices. PARTICIPANTS: Ninety-seven infants, aged 15 to 16 months, who had received three previous DTwP immunizations. SELECTION PROCEDURES AND INTERVENTIONS: Healthy children received the DTaP or DTwP vaccine. Infants received the MMR vaccine at a separate site and the OPV vaccine concurrently. Blood was obtained on day 0 and at 6 weeks. Adverse events were recorded by parents at specified times after immunization. MEASUREMENTS/RESULTS: Within 3 days of immunization, DTaP vaccine recipients had less fever, drowsiness, and irritability (P = .01, .04, .01, respectively). They also experienced less tenderness, erythema, and induration (.001, .001, and .002, respectively). There was no difference in the frequency of adverse reactions 6 to 14 days after immunization. Enzyme-linked immunosorbent assays were used to determine all antibody values. Antibody responses to filamentous hemagglutinin and pertussis toxoid were significantly greater in the DTaP group (P = .0001 and .02, respectively). Immune responses to the other measured antigens were similar. CONCLUSIONS: Simultaneous administration of the Lederle DTaP with MMR and OPV vaccines did not interfere with antibody response to pertussis antigens measured or measles, mumps, or rubella viruses and was associated with fewer local and systemic adverse events during the first 3 days following immunization when compared with the simultaneous administration of the DTwP, OPV, and MMR vaccines. We conclude that the DTaP vaccine can be administered at 15 months of age concurrently with the MMR and OPV vaccines.
