Liver abscess (LA) is a serious infectious disease, but is relatively rare in the paediatric population, especially in developed countries. Mostly, hepatic abscesses are pyogenic, caused by Staphylococcus aureus, while in extremely rare cases can be caused by parasites, such as Ascaris lumbricoides. Antimicrobial therapy and percutaneous drainage are the treatments of choice, lowering the mortality caused by this infection. We report a case of a 3-year-old girl admitted to the hospital for abdominal pain and a low-grade fever, with abdominal ultrasonography revealing a hepatic lesion. Initial laboratory tests showed moderate anaemia, thrombocytosis, eosinophilia, high inflammatory markers, and normal liver function. A computed tomography scan revealed two liver abscesses located subdiaphragmatically, and a high immunoglobulin E (IgE) value (22,300 U/mL). After excluding other possible etiologies, the patient was tested for parasitic infections. IgE for Ascaris lumbricoides came slightly higher. In addition to empirical antibiotic treatment, the patient received albendazole and made an uneventful recovery, with the full remission of the abscesses and without the need for drainage. In certain cases, parasites such as Ascaris lumbricoides are capable of inducing a T helper 2 (Th2) dominated immune response, predisposing the host to eosinophilia, hyperIgE, and increased susceptibility to bacterial infections. Early diagnosis and treatment in these cases may lead to less invasive therapy options in order to obtain a full recovery. To the best of our knowledge, this is the only reported case in the literature of a paediatric patient with parasite-induced liver abscesses, with extremely high IgE values, minimal symptomatology, that made a fast, full recovery without the need of drainage.
One of the most widespread bacterial infections worldwide, Helicobacter pylori is thought to affect almost half of the world’s population. Due to rising antibiotic resistance, treatment should be tailored according to antibiotic susceptibility testing (AST). This study aims to evaluate Helicobacter pylori antibiotic resistance and its therapeutic efficacy in children. We conducted a prospective, single-center study, that evaluated 68 children referred for upper gastrointestinal endoscopy (UGE) following chronic dyspeptic syndrome. Each patient underwent multiple biopsies to perform bacterial cultures with AST and histopathological examinations for the diagnosis. Patients without antibiotic resistance or negative cultures received a 10-day sequential therapy, while the others had the antibiotic regimen tailored based on AST. Fifty-nine patients with a positive biopsy-based diagnosis (24 males) were finally included. Bacterial cultures with AST were positive for 13 patients (22.03%) and the antibiotic resistance for clarithromycin was 15.38%. Fifty-seven patients were administered sequential therapy with an eradication rate of 94.73%. Clarithromycin-resistant patients were successfully treated with 10-day triple therapy of esomeprazole, amoxicillin, and metronidazole. Although bacterial cultures had a low positivity rate, sequential therapy had a successful eradication rate. Further studies are necessary to better assess Helicobacter pylori antibiotic resistance to provide tailored treatment and identify children that need closer monitoring.
Helicobacter pylori (H. pylori) is one of the most common chronic bacterial infections in the world, and it is currently estimated that approximately half of the world's population is infected with the bacterium. The correct diagnosis and effective treatment of H. pylori gastric infection are essential in controlling this condition. The available diagnostic methods have advantages and limitations related to factors such as age of patients, technical difficulty level, costs and extensive accessibility in hospitals. The eradication therapy of H. pylori infection is still a challenge for gastroenterologists. One of the main causes of failure in H. pylori eradication is antibiotic resistance. Biopsy cultures are the most widely used methods among the antimicrobial susceptibility tests. In case of a negative culture, H. pylori can be clearly recognised in histological sections. The sensitivity and specificity of histology for the diagnosis depend on clinical settings, density of colonisation and the experience of the histopathologist. A prospective study was performed in order to analyse patients with H. pylori gastric infection with positive histology and positive culture versus positive histology and negative culture.
Pediatric multisystem infl ammatory syndrome (PMIS) appears to be a relatively rare complication of COVID-19 in children, occurring in less than 1% of children with confi rmed SARS-CoV-2 infection. This condition can appear several weeks after the acute SARS-CoV-2 infection and is assumed to be a delayed immune response to coronavirus disease 2019 which can lead to a severe cardiovascular involvement. In this retrospective study, our main purpose was to summarize the clinical data from three types of onsets in patients diagnosed with PMIS and report the experience to the known data in the literature. We put the emphasis on the course of management considering the three different presenting faces of the PMIS in children. All patients received IV immunoglobulin and antiplatelet treatment, 66% (2 of 3) necessitated inotropic support, corticosteroid therapy (metilprednisolon), anticoagulation, 33% (1 of 3) received Anakinra (antagonist of the interleukin 1 receptor). All of them received cardiac remodeling treatment with Lisinopril and Bisoprolol (associated or not with Spironolactone and Furosemide). Evolution was good with discharge in approximately 2 weeks from admission, without symptoms, and with cardiac improvement at echocardiography. PMIS is an alarming situation that necessitate multidisciplinary approach and a complex management. The cardiac evaluation is crucial in risk evaluation and guidance for a correct approach of the disease.
Hymenolepis diminuta is primarily a rodent parasite that is ubiquitously distributed worldwide, but with only a few cases described as human infections. We report a case of Hymenolepis diminuta infection in a 15-month-old child, living in an urban setting, with no previous medical history. The patient presented with two episodes of seizures, and complaints of abdominal pain, vomiting, and diarrhea, with no apparent history of rodent contact. Furthermore, the patient’s gastrointestinal symptoms were linked to the emission of suspected tapeworm proglottids in the feces. After excluding other possible etiologies, a diagnosis of Hymenolepis diminuta infection was made, based on the examination of characteristic eggs in a concentrated stool specimen. The infant was successfully treated with praziquantel and fully recovered. After two weeks, the stool sample was free of Hymenolepis diminuta eggs. The clinical follow-up over the next 3 years was normal. Hymenolepis diminuta is rarely found in humans, and, when present, the infection is frequently asymptomatic. Abdominal pain, irritability, itching, eosinophilia, and seizures have also been reported. In this paper, we report, for the first time in the literature, an infection with Hymenolepis diminuta in a Romanian infant who had atypical neurological presentation, with full recovery, without subsequent neurological sequelae.
