RSV bronchiolitis was the most important risk factor for the development of asthma and allergen-specific IgE, although a family history of atopy or asthma further increased the risk.

Objective. To study the occurrence of bronchial obstructive symptoms and immunoglobulin (Ig) E antibodies after respiratory syncytial virus (RSV) bronchiolitis in infancy. Previous studies of this subject have mostly been retrospective or without controls, or the controls have not been followed prospectively. Design. This was a prospective cohort study with matched controls. Participants. Forty-seven infants had experienced RSV bronchiolitis severe enough to cause hospitalization at a mean age of 3½ months. For each child with RSV infection, two controls were acquired from the local Child Health Center and matched for date of birth, sex, and residence. Only one control was obtained for one RSV child, and the control group thus contained 93 children. Methods. All the children underwent two follow-up examinations, the first one at a mean age of 1 year and the second at a mean age of 3 years. At the first follow-up, a skin-prick test against egg white was performed, and serum IgG antibodies against RSV were measured. At the second follow-up, serum IgE antibodies were measured using screening tests for common food and inhalant antibodies, and skin-prick tests against egg white, cat, birch, and mite allergen were performed. Hereditary and environmental factors (passive smoking, indoor furred animals) and duration of breast-feeding were recorded. Results. At the first follow-up, 89% in the RSV group and 27% in the control group had IgG antibodies against RSV (P < .001). At the second follow-up, asthma, defined as three episodes of bronchial obstruction verified by a physician, was found in 11 of 47 children (23%) in the RSV group and in 1 of 93 children (1%) in the control group (P < .001). A positive test for IgE antibodies was noted in 14 of 44 (32%) RSV children and in 8 of 92 (9%) children in the control group (P = .002). An analysis of risk factors for the development of asthma and IgE antibodies on the whole group of 140 children showed that RSV bronchiolitis was the most important risk factor, and a family history of atopy or asthma further increased the risk. Conclusions. Respiratory syncytial virus bronchiolitis during the first year of life apparently is an important risk factor for the development of asthma and sensitization to common allergens during the subsequent 2 years, particularly in children with heredity for atopy/asthma.

Common Manifestation

Background: Acute lower respiratory infection (ALRI) is one of the main causes of morbidity and mortality in children under five years of age, and the respiratory syncytial virus (RSV) remains its leading etiological factor. Although RSV infections occur in all age groups, the most severe course is observed among children. The clinical manifestations include both mild upper respiratory infections and severe infections of the lower tract, such as bronchiolitis and pneumonia that can lead to hospitalization and severe complications, including respiratory failure. Objectives: The study aimed to evaluate the manifestations of RSV infection in hospitalized children younger than 18 months of age and predictors of disease severity, as well as their comparison with the same age group hospitalized due to ALRI of different etiology. Methods: A retrospective analysis was performed on medical records of 448 children hospitalized due to ALRI. The analysis was performed on the total study group and subgroups of children with positive and negative results of the nasal swab for RSV detection. In each group, clinical data, laboratory test results, and imaging results were analyzed. Results: The most common manifestation was pneumonia (n = 82; 63.08%). Otitis media was observed mainly in children under six months of age with lowered inflammatory markers (P < 0.05), conjunctivitis in those with a positive family history of allergies (P < 0.05), and pneumonia in children under six months of age, with lower blood oxygen saturation and inflammatory markers, features of acidosis, and fever-free course (P < 0.05). Respiratory failure affected 13 children (10%). However, no predictors of this complication were noted. Conclusions: As pneumonia was the most common manifestation in children with both RSV-positive and RSV-negative ALRI, it seems advisable to perform the imaging of the lungs on admission and carefully monitor the child’s condition during hospitalization. In both groups, special attention should be paid to the youngest children with low inflammatory markers on hospital admission, increased clinical symptoms, and family history of allergies. Nevertheless, widely known risk factors of RSV infection itself do not reflect the risk of developing pneumonia or respiratory failure in its course.

Importance Migraine is a highly prevalent and disabling primary headache disorder that is two to three times more prevalent in young women. Among females, there is a steep increase in incidence from puberty to young adulthood, but the mechanisms for the increase are unknown. Objective To determine if age of menarche is a risk factor for developing migraine headache vs. non-migraine headache by young adulthood. Design A prospective cohort study, The Growing Up Today Study (GUTS), of adolescents who have been followed since 1996, when they were nine, to 14 years of age. Headache questions were included on the 2007 and 2010 surveys. Setting Youth from across the United States who are offspring of women participating in the Nurses’ Health Study II. Participants 6112 female participants who had provided data on headache symptoms, age at menarche and family history of migraine and were followed through 2007 or 2010 were included in this analysis. Main outcomes Migraine or non-migraine headache. Results Many females had a history of headaches, with approximately equal numbers reporting symptoms consistent with migraine (29.7%) and non-migraine headaches (25.3%). We found that, independent of age and family history of migraine, each one-year delay in onset of menarche decrease the odds of migraine by 7% (odds ratio (OR) = 0.93, 95% confidence interval (CI) 0.89–0.97), but was not related to non-migraine headaches. Conclusions and relevance The findings of this study suggest that early puberty increases the risk of developing migraines by young adulthood. As such, the study emphasizes the need for understanding the pathophysiological links between puberty and developmental changes that occur in the brain during that period and the mechanisms of onset of the migraine disease and its trajectory.
