RESUMO

BACKGROUND: Use of rotavirus vaccines worldwide since 2006 has led to a significant impact on the burden of rotavirus disease. However, only a third of European countries have introduced rotavirus vaccination in their immunization programs. In October 2014, rotavirus vaccination was introduced for Norwegian infants under strict age restrictions. Exclusive use of the monovalent rotavirus vaccine (RV1) and high vaccination coverage from the beginning enabled evaluation of the impact of this vaccine during the first 4 years after introduction. METHODS: Prospective laboratory-based surveillance among children <5 years of age hospitalized for acute gastroenteritis at 5 Norwegian hospitals was used to assess the vaccine effectiveness of 2 vaccine doses against rotavirus hospitalization in a case-control study. We used community controls selected from the national population-based immunization registry, and test-negative controls recruited through hospital surveillance. We also assessed the vaccine impact by using time-series analysis of retrospectively collected registry data on acute gastroenteritis in primary and hospital care during 2009-2018. RESULTS: Vaccine effectiveness against rotavirus-confirmed hospitalization was 76% (95% confidence interval [CI]: 34%-91%) using test-negative controls, and 75% (95% CI: 44%-88%) using community controls. In the postvaccine period, acute gastroenteritis hospitalizations in children <5 years were reduced by 45% compared with the prevaccine years (adjusted incidence rate ratios 0.55; 95% CI: 0.49-0.61). Reduction in hospitalizations was also seen in cohorts not eligible for vaccination. Rates in primary care decreased to a lesser degree. CONCLUSIONS: Four years after introduction of rotavirus vaccination in the national childhood immunization program, we recorded a substantial reduction in the number of children hospitalized for acute gastroenteritis in Norway, attributable to a high vaccine effectiveness.

RESUMO

AIM: Using routine blood sampling in a gastroenteritis diagnostic workup is debatable. This study examined the relationship between the severity of acute gastroenteritis and blood test abnormalities. METHODS: We prospectively enrolled children under five years of age referred for outpatient or inpatient management for gastroenteritis from February 2014 to April 2016. The four study hospitals cared for 30% of Norwegian children. The severity of gastroenteritis was assessed using Vesikari scores. Blood samples were analysed at each hospital. RESULTS: The 659 children had a median age of 19 months. The rotavirus was found in 314/514 children with stool samples (61%). Severe gastroenteritis, indicated by a Vesikari score of ≥11, was found in 392/549 (71%) with completed scores, but only 40 of 649 (6%) assessed for dehydration were more than 5% dehydrated. None had sodium <130 mmol/L. Glucose of 3.0-3.3 mmol/L was detected in 52/578 (9%) and <3.0 mmol/L in 33/578 (6%). Hypoglycaemia, elevated urea, low bicarbonate and negative base excess were associated with disease severity. The duration of vomiting and the rotavirus infection were associated with hypoglycaemia. Elevated urea, low bicarbonate and negative base excess had high specificities, but low sensitivities. CONCLUSION: Hypoglycaemia was common in acute gastroenteritis, but major electrolyte disturbances were infrequent.

RESUMO

BACKGROUND: Norway introduced routine rotavirus immunization for all children born on or after September 1, 2014. We estimated the healthcare burden of all-cause gastroenteritis and rotavirus disease in children <5 years old to establish the prevaccine baseline and support the ongoing immunization program. METHODS: We examined national registry data on gastroenteritis-associated primary care consultations and hospitalizations for 2009-2013 and data on all deaths in children <5 years old reported during 2000-2013. We also established rotavirus hospital surveillance from February 2014 through January 2015. RESULTS: Before vaccine introduction, 114.5 cases per 1000 children <5 years old were treated in primary care and 11.8 children per 1000 were hospitalized with gastroenteritis annually. During hospital surveillance, rotavirus was detected in 65% (95% confidence interval: 60-70) of inpatient gastroenteritis cases. We estimated that 4.0 inpatient and 2.3 outpatient cases per 1000 children were seen in hospital with rotavirus disease annually, suggesting that 1 in 32 children was hospitalized by age 5. Additional 30.6 rotavirus cases per 1000 children consulted primary care annually or 1 in every 7 children by the age of 5 years. Rotavirus-associated mortality was estimated at 0.17 deaths per 100,000 children <5 years old, corresponding to 1 death every second year. CONCLUSIONS: Rotavirus remains the primary cause of severe gastroenteritis in children in Norway. The unique population-based registers, in combination with an established rotavirus surveillance platform, provide a well-suited setting to evaluate the impact of rotavirus vaccination.

RESUMO

Abdominal pain combined with fever is common during childhood. We present a 12-year-old girl who was admitted to hospital with abdominal pain, fever and nausea, but she also complained of cough, weight loss and night sweat. Investigations revealed multiple and randomly distributed lung nodules, impaired lung function, meningitis and multiple small brain lesions, consistent with tuberculomas. The polymerase chain reaction was positive for Mycobacterium tuberculosis in sputum. Cultures of sputum and cerebrospinal fluid were also positive and confirmed miliary tuberculosis with concomitant meningitis. The result of the Mantoux test was 13 mm and that of the Quantiferon-TB Gold was 5.17 IU/ml. She was given four antituberculous drugs (isoniazide, rifampicin, pyrazinamide and ethambutol) for two months and two drugs (isoniazide and rifampicin) for an additional ten months. The intracranial tuberculomas increased in size during the first two months of treatment, but demonstrated regression after seven months. The girl was HIV-negative and had no sign of immunodeficiency, but had recently been ill with mononucleosis and varicella infections. She recovered completely. The combination of miliary tuberculosis and meningitis is uncommon, particularly among previously healthy children of this age. Temporary immune suppression, caused by viral infections, could possibly explain the unusual clinical course. Pediatricians should be aware of miliary tuberculosis as a possible diagnosis in children presenting with common symptoms.

RESUMO

OBJECTIVE: To explore obstructions for quality care from experiences by patients suffering from chronic fatigue syndrome (CFS). METHODS: Qualitative case study with data drawn from a group meeting, written answers to a questionnaire and a follow-up meeting. Purposeful sample of 10 women and 2 men of various ages, recruited from a local patient organization, assumed to have a special awareness for quality care. RESULTS: CFS patients said that lack of acknowledgement could be even worse than the symptoms. They wanted their doctors to ask questions, listen to them and take them seriously, instead of behaving degrading. Many participants felt that the doctors psychologized too much, or trivialized the symptoms. Participants described how doctors' lack of knowledge about the condition would lead to long-term uncertainty or maltreatment. Even with doctors who were supportive, it would usually take months and sometimes years until a medical conclusion would be reached, or other disorders were ruled out. Increased physical activity had been recommend, but most of the informants experienced that this made them worse. CONCLUSION: Current medical scepticism and ignorance regarding CFS shapes the context of medical care and the illness experiences of CFS patients, who may feel they neither get a proper assessment nor management. PRACTICE IMPLICATIONS: CFS patients' reports about patronizing attitudes and ignorance among doctors call for development of evidence based strategies and empowerment of patients, acknowledging the patients' understanding of symptoms and the complex nature of the disease. The NICE guidelines emphasize the need of patient participation and shared decision-making.
