ABSTRACT

BACKGROUND: While the burden of rotavirus infection with regard to hospitalizations has been extensively investigated, there are sparse data on the cost and impact of this infection on the ambulatory part of the health system in Israel. OBJECTIVES: To investigate the burden of rotavirus infection on the ambulatory system in Israel. METHODS: Infants younger than 3 years examined for acute gastrointestinal symptoms in four pediatric clinics had their stool tested for rotavirus. The parents were contacted 7-10 days later and questioned about the symptoms of illness, medications given, use of diapers, consumption of formula, and any loss of parents' workdays. RESULTS: Rotavirus was detected in 71 of the 145 stool samples tested (49%). A total of 54 parents responded to the telephonic survey. Patients' mean age was 15.4 months. Three patients were hospitalized due to the illness. The mean duration of fever was 1.7 days. Infants with rotavirus gastroenteritis had on average 2.25 days of vomiting and 7.5 days of diarrhea. The average number of workdays lost was 2.65 days per RVGE case. The cost of the average case of RVGE in Israel is 257 euros; 69.64% of this cost (179 euros) is due to parental work loss. CONCLUSIONS: Our results indicate that the economic impact of the ambulatory cases in Israel is quite significant.

ABSTRACT

Genetic defects along the interleukin (IL)-12/interferon (IFN)-gamma pathway have been found in patients with mendelian susceptibility to mycobacterial disease (MSMD) caused by live BCG vaccine or non-tuberculous Mycobacterium (NTM) species, highlighting the crucial role of this axis in human immunity to Mycobacterium. The aims of this study were to characterize healthy children presenting with cervical lymphadenitis caused by NTM and to investigate their IL-12/IFN-gamma pathway. Epidemiological, clinical, laboratory and pathological findings were reviewed retrospectively. Blood samples from five patients and healthy controls were in vitro activated with BCG, BCG + IL-12 and BCG + IFN-gamma and levels of IL-12p40 and IFN-gamma were measured. Fourteen patients (11 males, median age 24 months, range 12-78 months) were studied. The mean duration of illness before diagnosis was 9.1 weeks. Mycobacterium tuberculosis purified protein derivate (PPD) was positive in all patients (mean 14.5 +/- 9.8 mm). Caseous granuloma was found in all ten patients who underwent excision biopsy. However, acid fast stain was positive in only five children and cultures were positive in only three cases. The amplified M. tuberculosis direct test was negative in all tested cases. No significant differences in IL-12p40 and IFN-gamma levels were found between patients and controls. In spite of the normal response as measured in the screening test, it is still possible that patients might have a monogenic/mendelian disease for which the genetic defect(s) have yet to be elucidated. Alternatively, some single nucleotide polymorphisms along the IL-12/IFN-gamma axis might be associated with an isolated cervical lymph node infection and not a disseminated disease in children.
