Early anakinra treatment improves cardiac outcome of multisystem inflammatory syndrome in children, regardless of disease severity.

OBJECTIVE: The main aim of this study was to define the best treatment option for multisystem inflammatory syndrome in children (MIS-C) and to analyse the role of anakinra. METHODS: This is a multicentre retrospective cohort study. Patients were treated according to the attending physician's decision. The patients were divided into four groups on the basis of the first treatment at time of admittance: (i) IVIG, (ii) IVIG and methylprednisolone (≤2 mg/kg/day), (iii) IVIG with high-dose methylprednisolone (>2 mg/kg/day) and (iv) anakinra with or without IVIG and/or methylprednisolone. Primary outcomes were defined as the presence of at least one of the following features: death, the failure of initial treatment, meaning the need for additional treatment for clinical worsening and cardiac involvement at the end of follow-up. RESULTS: Two hundred thirty-nine patients were recruited. At univariate analysis, persistent heart involvement at discharge was more frequent in those not receiving anakinra as initial treatment (3/21 vs 66/189; P = 0.047). After comparisons between the four treatment regimens, adjusting for the propensity score, we observed that early treatment with anakinra was associated with a lower probability of developing persistent heart disease at the end of follow-up (odds ratio: 0.6; 95% CI: 0.4-1.0). CONCLUSION: We report that early treatment with anakinra is safe and very effective in patients with severe MIS-C. In addition, our study suggests that early treatment with anakinra is the most favourable option for patients with a higher risk of developing a severe disease outcome.

Pediatric Tuberculosis in Italian Children: Epidemiological and Clinical Data from the Italian Register of Pediatric Tuberculosis.

Tuberculosis (TB) is one of the leading causes of death worldwide. Over the last decades, TB has also emerged in the pediatric population. Epidemiologic data of childhood TB are still limited and there is an urgent need of more data on very large cohorts. A multicenter study was conducted in 27 pediatric hospitals, pediatric wards, and public health centers in Italy using a standardized form, covering the period of time between 1 January 2010 and 31 December 2012. Children with active TB, latent TB, and those recently exposed to TB or recently adopted/immigrated from a high TB incidence country were enrolled. Overall, 4234 children were included; 554 (13.1%) children had active TB, 594 (14.0%) latent TB and 3086 (72.9%) were uninfected. Among children with active TB, 481 (86.8%) patients had pulmonary TB. The treatment of active TB cases was known for 96.4% (n = 534) of the cases. Overall, 210 (39.3%) out of these 534 children were treated with three and 216 (40.4%) with four first-line drugs. Second-line drugs where used in 87 (16.3%) children with active TB. Drug-resistant strains of Mycobacterium tuberculosis were reported in 39 (7%) children. Improving the surveillance of childhood TB is important for public health care workers and pediatricians. A non-negligible proportion of children had drug-resistant TB and was treated with second-line drugs, most of which are off-label in the pediatric age. Future efforts should concentrate on improving active surveillance, diagnostic tools, and the availability of antitubercular pediatric formulations, also in low-endemic countries.

[Reports on nine cases of spondylodiscitis]. / Osservazioni su nove casi di spondilodiscite.

Spondylodiscitis is an infection of the intervertebral disk and the adjacent vertebrae, with or without associated epidural or psoas abscesses. It is a serious disease both due to its long-term course and the possible outcomes. It is frequently caused by S. aureus and, in endemic areas, by Mycobacterium tuberculosis and Brucella spp. We describe 9 cases, from October 2004 to August 2005, all spontaneous diseases occurring in adults (mean age 64 years). The site of infection was lumbar in 7, lumbar-sacral in 1 and dorsal in 1. None were associated to sepsis. The causative bacteria were known in 6 cases (1 BK, 1 S. aureus, 4 Brucella) and unknown in 3 cases. In all cases therapy was only medical. Significant circulation in Sicily of both Mycobacterium tuberculosis and Brucella spp. make those microorganisms the most frequent agents of spondylodiscitis.

[Hormonal, auxological and clinical follow-up in children with connatal HIV infection: personal records]. / Valutazione plurispecialistica per un follow-up clinico, auxologico ed endocrino di pazienti con infezione connatale da HIV: dati di una casistica personale.

Auxological and endocrinological complications frequently occur in children with connatal HIV infection. These complications seem to be related both to the infection itself and the antiretroviral therapy. Many children consequently show height-weight and pubertal retardation without any evidence of hormonal deficit. We studied 10 children with connatal HIV infection who were enrolled in this analysis and followed up for 7 years in order to evaluate their height-weight growth, pubertal maturation, bone age progression and hormonal pattern [basal Growth hormone (GH) and GH after Clonidine or Insulin stimulation, Insulin-like Growth Factor 1 (IGF-1), Insulin-like Growth Factor Binding Protein 3 (IGFBP-3), FSH, LH, ACTH and Cortisol, TSH, fT4, T4, T3, Ab-TGO, Leptin]. Three children showed a height lower than 3rd centile during the first two years of their life and in prepubertal age, with recurring improvement in their growth rate. Weight growth was very compromised in one girl, remaining firmly lower than 3rd centile during the follow-up. Three children presented a weight lower than 3rd centile until they were two years old. However, a height growth rate higher than 10th centile was found in nine children throughout the follow-up, while it was pathological in five children. The blood level of Leptin was higher at the beginning of the study: 0.82 - 11.68 ng/l (M+/-DS: 3.29+/-4.15) than at its conclusion: 0.2 - 3 ng/l (M+/-DS: 1.65+/-1.01). There was a statistically significant correlation between leptinemia and the CD4/CD8 count (p: 0.010; r: 0.916) and the CDC classification (p: 0.006; r: 0.937), indicating a strong relationship with the degree of virological and immunological impairment. The authors stress the importance of a careful height-weight growth rate control in HIV-infected children, as it reflects the clinical and virological course of the disease. Adequate control of the infection allows physiological growth in most patients. Moreover, we emphasize the utility of IGFBP-3 and IGF-1 measurements, since they represent growth markers which are more exact and better capable of reproduction than GH.

[Epidemiology of paediatric tuberculosis today]. / Epidemiologia della tubercolosi pediatrica oggi

Tuberculosis (TB) kills 2 million people each year in the world, of which 250,000 are children. In Italy, paediatric TB is 3.5% of total cases with a steady trend in the last ten years. Childhood tuberculosis remains a disease of great concern because its occurrence always indicates recent transmission and is a pivotal indicator of effectiveness of TB control efforts. The epidemiological study, including DNA fingerprinting, of 71 children affected by TB - 62 pulmonary, 9 meningitis, 2 renal- shows that the source case is frequently a parent or household member. Sensitivity to anti-tubercular drugs was tested for 18/20 isolates obtained from the children and 21/44 isolates obtained from infection sources with 5 resistant strains in each group. One child was resistant to isoniazid, and one adult source to rifampin. Multi-drug resistance was observed in 8 cases: 4 children and 4 sources. In the children's case, we may use the term primary resistance as the patients have not been previously treated with the drugs. These children's treatment lasted longer, not only because their regimen had been changed, but also because of their delayed clinical-radiological response to the treatment. These data suggest that it would be opportune to re-evaluate current treatment of childhood tuberculosis, encouraging active and integrated cooperation between epidemiologists, infectious disease specialists and paediatricians.
