Analysis of the course and treatment of toxocariasis in children—a long-term observation

Toxocariasis is a helminthozoonotic disease caused by ascarid larvae of Toxocara genus: Toxocara canis and Toxocara cati. In the reported study, the clinical course of toxocariasis and administered therapy were evaluated in 103 children. The majority of the children (68.9%) were from the rural environment, with a prevalence of boys (62.1%). At diagnosis of infection, 36 (35%) children reported recurrent abdominal pain, 19 (18.4%) headache, 6 (5.8%) loss of appetite, 2 subfebrile conditions, and 2 arthralgia, Moreover, 23 (22.3%) children demonstrated symptoms of atopic diseases; in 30 (29.1%) children, moderate enlargement of lymphatic nodes was noted. In five children (4.9%), ophthalmic examination revealed unilateral changes in the eye: in two cases retinitis; in one case fibrotic lesions in the vitreous body, complicated 1 year from diagnosis by retinal detachment; and in other children parafoveal lesions and cataract. Only two children with ocular changes at diagnosis reported visual disorders. In 64.3% of children, eosinophilia was observed. A covert form of the disease was diagnosed in 95.1% of the children and an ocular form in 4.9%. In all the children, antiparasitic treatment was implemented, repeated several times in some of them. After therapy, the mean titer of specific antibodies, the number of children with abdominal pains and enlarged lymphatic nodes were decreased, while headaches maintained at unchanged levels. In approximately one fourth of the children with negative results of antibodies after the therapy, the symptoms of the disease were still reported. Evaluation of the efficacy of treatment is not easy due to non-characteristic symptoms and low kinetics of specific anti Toxocara IgG decrease; however, high IgG titers suggest non-effective treatment of concomitant infection requiring subsequent therapy. Due to risk of ocular form, which may develop in any stage of the disease, irrespectively of specific antibodies concentrations, it seems justified to implement antiparasitic treatment in all children infected with T. canis

HBV DNA suppression during entecavir treatment in previously treated children with chronic hepatitis B

The aim of this study was to assess HBV DNA suppression after 24 weeks of treatment with entecavir in previously treated children with CHB. Thirty children aged 5–17 years (25 males and 5 females) with CHB were treated with entecavir 0.5 or 1 mg daily. Twenty-two children were HBeAg-positive, eight were HBeAg-negative, and in eight HBV polymerase mutations were detected. After 24 weeks of treatment, mean and median HBV DNA levels and ALT activity were lower versus baseline, overall and in both subgroups. The overall median HBV DNA level decreased from 1.2 x 107 IU/mL to 3.3 x 102 IU/mL (p < 0.000004), in HBeAg-positive from 7.8x107 IU/mL to 6.3x103 IU/mL (p < 0.00004), and in HBeAg-negative from 2.5x104 IU/mL to 5.01x101 IU/mL (p < 0.03). The serum HBV DNA disappearance was observed in 7/8 (88%) HBeAg-negative and in 5/22 (23%) HBeAg-positive patients. The overall mean ALT activity decreased from 164+ 290 U/L to 34.1+ 18.9 U/L (p < 0.000007), in HBeAg-positive from 214+326 U/L to 38.59+19.2 U/L (p < 0.000074), and in HBeAg-negative from 27+14 U/L to 20+8 U/L (p < 0.03). Twenty-four weeks of treatment with entecavir results in suppression of HBV DNA in a substantial proportion of children previously treated ineffectively with CHB

Mycotic complications of shunt infection in children with primary hydrocephalus. Recently, the incidence of fungal infections in children, including cbildren with shunt-dependent hydrocephalus, has increased. The analysis comprised 8 cbildren treated in the III Clinic of Pediatrics of ICZMP during the period of 12 months (12% of all infectious complications of the shunt system). The clinical picture of fungal infection included Symptoms of shunt dysfunction: febrile conditions, vomiting, distress and loss of appetite. The most common pathogens isolated from the cerebro-spinal fluid were fungi from the Candida species. Mean value of pleocytosis in the cerebro-spinal fluid was 812 cell/μ, and mean protein concentration was 311 mg/dl. Treatment consisted of monotherapy with Dillucan, monotherapy with Ancotil or combined treatment with Ancotil and Amphotericine B. The drugs were administered intravenously and intraventricolarly after removal of the shunt and application of external drainage. Sterility of cerebro-spinal fluid was obtained in the shortest time with the use of Ancotil. Propbylactic application of antifungal drugs decreases the frequency of infections in children with shunt-dependent hydrocepbalus
