Sixteen years of global experience with the first refrigerator-stable varicella vaccine (Varilrix).

Without vaccination, chickenpox (varicella) will affect almost every person in the world during their lifetime. The burden of disease due to varicella is often unrecognized. Varilrix is a varicella vaccine derived from the Oka strain of varicella virus. The vaccine, as a frozen formulation, was licensed for use in 1984 and was the first commercially available varicella vaccine. It subsequently became the first refrigerator-stable varicella vaccine; its development commenced in 1991 and it has been licensed for use since 1994. Varilrix is indicated for use in high-risk groups, potentially immunocompromised individuals, and healthy subjects in many countries. This article reviews data from extensive worldwide experience with the refrigerator-stable version of the vaccine, including information derived from its use in over 10,000 individuals participating in clinical trials investigating its immunogenicity, efficacy, effectiveness, and safety, as well as postmarketing data including its use in universal mass vaccination programs. Sixteen years of clinical and postmarketing experience with the same formulation represents the longest and most extensive experience with a refrigerator-stable varicella vaccine worldwide. Varilrix, in conjunction with the trivalent measles-mumps-rubella vaccine Priorix, has also been the basis for clinical development of the tetravalent measles-mumps-rubella-varicella vaccine (Priorix-Tetra).

Varicella vaccination in children with atopic eczema.

Chickenpox in children may be complicated by local or systemic bacterial infections. Group A streptococci and S. aureus are the predominant pathogens. Children with atopic dermatitis are particularly prone to bacterial superinfection. After the introduction of universal varicella vaccination in the USA ten years ago, the number of serious bacterial soft tissue infections in children dropped significantly. Since 2004, the VZV immunization has also been included in the routine German series.Many children with atopic dermatitis have not been immunized because of concerns on the part of parents or physicians. Recent studies demonstrated the safety and efficacy of VZV vaccination in children with atopic dermatitis who appear to benefit particularly from this vaccination.

Membranous nephropathy associated with familial chronic ulcerative colitis in a 12-year-old girl.

Glomerulonephritis is a rare complication in patients with inflammatory bowel disease. We report a case of membranous nephropathy (MN) in a 12.6-year-old girl with chronic ulcerative colitis. The girl was referred to the hospital with bloody diarrhea and arthralgia. Routine urinalysis showed 1 g/m(2) protein excretion in 24 h. Serum ANCA titers were positive. The diagnoses were confirmed by coloscopy and kidney biopsy. The patient's mother had also suffered from ulcerative colitis in adolescence. Proteinuria normalized under treatment with prednisone (60 mg/m(2)/day) and azathioprine, which was initiated to treat the colitis. Chronic ulcerative colitis can be associated with glomerulonephritis.
