RESUMO
Data on features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children and adolescents are scarce. We report preliminary results of an Italian multicentre study comprising 168 laboratory-confirmed paediatric cases (median: 2.3 years, range: 1 day-17.7 years, 55.9% males), of which 67.9% were hospitalised and 19.6% had comorbidities. Fever was the most common symptom, gastrointestinal manifestations were frequent; two children required intensive care, five had seizures, 49 received experimental treatments and all recovered.

Viral and host factors can influence HIV-1 progression, among them human leucocyte antigen (HLA) has shown the strongest effect. However, studies on the functional contribution of HLA in controlling HIV progression toward AIDS are limited by multiple issues, including the viral strain variability within the study subjects. In this study, in a cohort of children infected with a monophyletic strain (CRF02_AG) during an outbreak, we evaluated the HIV-1 Gag, Vif, Vpr, Tat and hepatitis C virus E1/E2 (as control) proteins circulating in a cohort for the capability to be presented by the HLA molecules in the same population. A total of 70 Non-progressors and 37 Progressors to AIDS were evaluated. In the presence of a constant capability of HIV-1 to mutate in the region containing epitopes of Gag protein, the number of epitopes recognized in silico by the combination of the HLA alleles along the Gag consensus sequence is significantly higher in the Non-progressors compared with Progressors (HLA-A: Non-progressors = 1.532 ± 1.211, Progressors = 0.7714 ± 1.031, P = 0.0016; HLA-B: Non-progressors = 1.556 ± 1.298, Progressors = 1.000 ± 0.817, P = 0.0319; HLA-DR: Non-progressors = 13.30 ± 9.488, Progressors = 7.294 ± 6.952, P = 0.0006). Similar results were obtained for the other HIV-1 proteins Vif and Vpr, whereas no differences were obtained in the number of epitopes for the hepatitis C virus E1/E2 protein sequence or for the scrambled HIV-1 sequence. Finally, the results were confirmed also in a subgroup of subjects where both HLA typing and Gag sequence were available. In conclusion, in the absence of bias due to viral strain diversity, it is the overall fitting of the HLA molecules that are capable of better binding HIV-1 proteins in determining the major role in the control of HIV-1 replication and progression to AIDS.

Sotrovimab is a monoclonal antibody approved in adult and adolescents at high risk for COVID-19. Thirty-three children evaluated in five Italian paediatric centres received Sotrovimab infusion and were retrospectively enrolled from December 2021 to April 2022. In more than half of cases (19/33, 57.6%) Sotrovimab was prescribed off-label. Overall, the infusion was well tolerated with no significative differences in those receiving an off-label prescription. All children had a complete recovery. Data on the safety of Sotrovimab should be investigated in a larger paediatric cohort, considering the continuous selection of new SARS CoV-2 variants which may be more or less susceptible to the effects of the Sotrovimab.

BACKGROUND: COVID-19 is generally milder in children than in adults, however severe infection has been described in some patients. Few data are available on use of Remdesivir (RDV) in children, as most clinical trials focused on adult patients. We report a multicenter study conducted in 10 Italian Hospitals to investigate the safety of RDV in children affected by COVID-19. METHODS: We collected the clinical data of children with COVID-19 treated with RDV between March 2020 and February 2022 in 10 Italian hospitals. Clinical data were compared according to a duration of RDV therapy more or less than 5 days. Linear regression model was used to determine the association of significant variables from the bivariate analysis to the duration of RDV therapy. RESULTS: A total of 50 patients were included, with a median age of 12.8 years. Many patients had at least one comorbidity (78%), mostly obesity. Symptoms were fever (88%), cough (74%) and dyspnea (68%). Most patients were diagnosed with pneumonia of either viral and/or bacterial etiology. Blood test showed leukopenia in 66% and increased C-reactive protein (CRP) levels in 63% of cases. Thirty-six patients received RDV for 5 days, nine patients up to 10 days. Most children who received RDV longer were admitted to the PICU (67%). Treatment with RDV was well tolerated with rare side effects: bradycardia was recorded in 6% of cases, solved in less than 24 h after discontinuation. A mild elevation of transaminases was observed in 26% of cases, however for the 8%, it was still detected before the RDV administration. Therefore, in these cases, we could not establish if it was caused by COVID-19, RDV o both. Patients who received RDV for more than 5 days waited longer for its administration after pneumonia diagnosis. The presence of comorbidities and the duration of O2 administration significantly correlated with the duration of RDV therapy at the linear regression analysis. CONCLUSION: Our experience indicates that RDV against SARS-CoV-2 is safe and well-tolerated in pediatric populations at high risk of developing severe COVID-19. Our data suggest that delaying RDV therapy after diagnosis of pneumonia may be associated with a longer duration of antiviral therapy, especially in patients with comorbidities.

BACKGROUND: US Food and Drug Administration has issued Emergency Use Authorizations for hundreds of serological assays to support Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) diagnosis. The aim of this study is to evaluate, for the first time in children, the performance of three widely utilized SARS-CoV-2 serology commercial assays, Diesse Diagnostics (IgG, IgA, IgM) and Roche Diagnostics, both Roche Nucleocapsid (N) IgG and Roche Spike (S) IgG assays. METHODS: Sensitivity and 95% confidence intervals (CIs) were estimated for each of the three different serological tests and mixed and direct comparison were performed. Univariate and multivariate Poisson regression models were fitted to calculate incidence rate ratios and 95% CIs as estimate of the effects of age, gender, time on the serology title. A p-value < 0.05 indicated statistical significance. RESULTS: Overall, 149 children were enrolled in the study. A low sensitivity was found for Diesse IgA, IgM and IgG. Compare to Diesse, Roche S had a higher sensitivity at 15-28 days from infection (0.94, 95%CI: 0.73-1.0) and Roche N at 28-84 days (0.78, 95%CI: 0.58-0.91). When a direct comparison of IgG tests sensitivity was feasible for patients with pairwise information, Roche S and Roche N showed a statistically significant higher sensitivity compared to Diesse in all the study periods, whereas there was no difference between the two Roche tests. CONCLUSION: Roche S and Roche N serology tests seem to better perform in children. Large prospective studies are needed to better define the characteristics of those tests.

The fast diffusion of the SARS-CoV-2 pandemic have called for an equally rapid evolution of the therapeutic options.The Human recombinant monoclonal antibodies (mAbs) have recently been approved by the Food and Drug Administration (FDA) and by the Italian Medicines Agency (AIFA) in subjects aged ≥12 with SARS-CoV-2 infection and specific risk factors.Currently the indications are specific for the use of two different mAbs combination: Bamlanivimab+Etesevimab (produced by Eli Lilly) and Casirivimab+Imdevimab (produced by Regeneron).These drugs have shown favorable effects in adult patients in the initial phase of infection, whereas to date few data are available on their use in children.AIFA criteria derived from the existing literature which reports an increased risk of severe COVID-19 in children with comorbidities. However, the studies analyzing the determinants for progression to severe disease are mainly monocentric, with limited numbers and reporting mostly generic risk categories.Thus, the Italian Society of Pediatrics invited its affiliated Scientific Societies to produce a Consensus document based on the revision of the criteria proposed by AIFA in light of the most recent literature and experts' agreement.This Consensus tries to detail which patients actually have the risk to develop severe disease, analyzing the most common comorbidities in children, in order to detail the indications for mAbs administration and to guide the clinicians in identifying eligible patients.

Surgical site infections (SSIs), which are a potential complications in surgical procedures, are associated with prolonged hospital stays and increased postoperative mortality rates, and they also have a significant economic impact on health systems. Data in literature regarding risk factors for SSIs in pediatric age are scarce, with consequent difficulties in the management of SSI prophylaxis and with antibiotic prescribing attitudes in the various surgical procedures that often tend to follow individual opinions. The lack of pediatric studies is even more evident when we consider surgeries performed in subjects with underlying conditions that may pose an increased risk of complications. In order to respond to this shortcoming, we developed a consensus document to define optimal surgical antimicrobial prophylaxis (SAP) in neonates and children with specific high-risk conditions. These included the following: (1) colonization by methicillin-resistant Staphylococcus aureus (MRSA) and by multidrug resistant (MDR) bacteria other than MRSA; (2) allergy to first-line antibiotics; (3) immunosuppression; (4) splenectomy; (5) comorbidity; (6) ongoing antibiotic therapy or prophylaxis; (7) coexisting infection at another site; (8) previous surgery in the last month; and (9) presurgery hospitalization lasting more than 2 weeks. This work, made possible by the multidisciplinary contribution of experts belonging to the most important Italian scientific societies, represents, in our opinion, the most up-to-date and comprehensive collection of recommendations relating to behaviors to be undertaken in a perioperative site in the presence of specific categories of patients at high-risk of complications during surgery. The application of uniform and shared protocols in these high-risk categories will improve surgical practice with a reduction in SSIs and consequent rationalization of resources and costs, as well as being able to limit the phenomenon of antimicrobial resistance.
RESUMO
Compared to adults, severe or fatal COVID-19 disease is much less common in children. However, a higher risk for progression has been reported in infants. Different pediatric COVID-19 severity scores are reported in the literature. Methods: Subjects under 90 days of age admitted to 35 Italian institutions for COVID-19 were included. The severity of COVID-19 was scored as mild/moderate or severe/critical following the classification reported in the literature by Venturini, Dong, Kanburoglu, and Gale. To assess the diagnostic accuracy of each classification system, we stratified all enrolled patients developing a posteriori severity score based on clinical presentation and outcomes and then compared all different scores analyzed. Results: We included 216 infants below 90 days of age. The most common symptom was fever, followed by coryza, poor feeding, cough, and gastrointestinal manifestations. According to Venturini, Dong, Kanburoglu, and Gale's severity scores, 18%, 6%, 4.2%, and 29.6% of infants presented with severe/critical disease, respectively. A correlation analysis between these four scores and the a posteriori severity score assigned to all enrolled subjects was performed, and a crescent strength of correlation from Gale (R = 0.355, p < 0.001) to Venturini (R = 0.425, p < 0.001), Dong (R = 0.734, p < 0.001), and Kanburoglu (R = 0.859, p < 0.001) was observed. Conclusions: The percentage of infants with severe COVID-19 varies widely according to the score systems. A unique clinical score should be designed for neonates and infants with COVID-19.

BACKGROUND: Although eHealth technology makes it possible to improve the management of complex health care systems and follow up on chronic patients, it is not without challenges, thus requiring the development of efficient programs and graphic user interface (GUI) features. Similar information technology tools are crucial, as health care populations are going to have to endure social distancing measures in the forthcoming months and years. OBJECTIVE: This study aims to provide adequate and personalized support to complex health care populations by developing a specific web-based mobile app. The app is designed around the patient and adapted to specific groups, for example, people with complex or rare diseases, autism, or disabilities (especially among children) as well as Alzheimer or senile dementia. The app's core features include the collection, labeling, analysis, and sorting of clinical data. Furthermore, it authorizes a network of people around the patient to securely access the data contained in his or her electronic health record. METHODS: The application was designed according to the paradigms of patient-centered care and user-centered design (UCD). It considers the patient as the main empowered and motivating factor in the management of his or her well-being. Implementation was informed through a family needs and technology perception assessment. We used 3 interdisciplinary focus groups and 2 assessment surveys to study the contexts of app use, subpopulation management, and preferred functions. Finally, we developed an observational study involving 116 enrolled patients and 253 system users, followed by 2 feedback surveys to evaluate the performance and impact of the app. RESULTS: In the validated general GUI, we developed 10 user profiles with different privacy settings. We tested 81 functions and studied a modular structure based on disease or medical area. This allowed us to identify replicable methods to be applied to module design. The observational study not only showed good family and community engagement but also revealed some limitations that need to be addressed. In total, 42 of 51 (82%) patients described themselves as satisfied or very satisfied. Health care providers reported facilitated communication with colleagues and the need to support data quality. CONCLUSIONS: The experimented solution addressed some of the health system challenges mentioned by the World Health Organization: usability appears to be significantly improved when the GUI is designed according to patients' UCD mental models and when new media and medical literacy are promoted. This makes it possible to maximize the impact of eHealth products, thereby overcoming some crucial gaps reported in the literature. Two main features seemed to have potential benefit compared with other eHealth products: the modeling, within the app, of both the formal and informal health care support networks and the modular structure allowing for comorbidity management, both of which require further implementation.
RESUMO
Background: Many aspects of SARS-CoV-2 infection in children and adolescents remain unclear and optimal treatment is debated. The objective of our study was to investigate epidemiological, clinical and therapeutic characteristics of pediatric SARS-CoV-2 infection, focusing on risk factors for complicated and critical disease. Methods: The present multicenter Italian study was promoted by the Italian Society of Pediatric Infectious Diseases, involving both pediatric hospitals and general pediatricians/family doctors. All subjects under 18 years of age with documented SARS-CoV-2 infection and referred to the coordinating center were enrolled from March 2020. Results: As of 15 September 2020, 759 children were enrolled (median age 7.2 years, IQR 1.4; 12.4). Among the 688 symptomatic children, fever was the most common symptom (81.9%). Barely 47% of children were hospitalized for COVID-19. Age was inversely related to hospital admission (p < 0.01) and linearly to length of stay (p = 0.014). One hundred forty-nine children (19.6%) developed complications. Comorbidities were risk factors for complications (p < 0.001). Viral coinfections, underlying clinical conditions, age 5-9 years and lymphopenia were statistically related to ICU admission (p < 0.05). Conclusions: Complications of COVID-19 in children are related to comorbidities and increase with age. Viral co-infections are additional risk factors for disease progression and multisystem inflammatory syndrome temporarily related to COVID-19 (MIS-C) for ICU admission.
RESUMO
HIV-1 infection causes a severe T-cell impairment with alteration of immune response. However, in children the natural decline of lymphocytes and CD4 cells in early life makes it more difficult to monitor immunocompetence and progression of HIV-infection. Aim of this study was to characterize the CD8 response in non-vertically HIV-infected children exposed persistently to viremia and in HIV-infected children controlling efficiently viremia by ART, by analysing the effect of persistent viremia on CD4 and CD8 T-cells count, HIV-specific immune-response and naive/memory pattern of CD8 T-cell. Whereas, no differences of CD4 count between viremic patients and viral controllers were observed (1046.9 +/- 472.1 cells/microl vs 1101.3 +/- 415.4 cells/microl; p > 0.05), CD8 count was higher in the viremic patients (1080.6 +/- 652.1 cells/microl vs 747.5 +/- 389.9 cells/microl, p < 0.05). In viremic patients, HIV-specific CD8 T-cells correlated with viral load. However, in this group a loss of HIV-specific CD8 response was associated with a 7 fold decrease of naïve and increase of pre-effector CD8 T-cells (62.8% +/- 10.21% vs 10.37% +/- 7.91%, p < 0.03). Persistent exposure to viremia alters HIV-specific CD8 response possibly through a persistent immune activation process leading to exhaustion of naive CD8 T-cells and skewed maturation of memory subset. Therefore, memory CD8 T-cells might lose the ability to respond correctly and efficiently to HIV-antigen exposure.

BACKGROUND: Measles is a highly communicable infection with potentially severe complications. It is rarely reported in high-income countries and the limited awareness and experience of pediatricians may result in misdiagnosis. The present study aimed at investigating physician's ability and timing to reach diagnosis during a recent outbreak in Italy. METHODS: The Italian Society for Pediatric Infectious Diseases conducted a retrospective, multicenter study in children hospitalized for measles between 1 January 2016 and 30 August 2017 in secondary and tertiary care hospitals. The appropriateness of diagnosis at admission, the time to reach clinical diagnosis, and serological confirmation of measles were recorded. RESULTS: At hospital admission, measles was misdiagnosed in 101 (40.5%) of the 249 children (median age, 14.5 months) enrolled. The appropriate diagnosis increased from 30% to 72.5% during the period of observation (P < .001). A greater chance of receiving an appropriate diagnosis was demonstrated in children who reported a contact with measles (odds ratio [OR], 5.2; 95% confidence interval [CI], 3.0-9.2) or in those seen in institutions that managed more cases (OR, 7.39; 95% CI, 3.22-16.9; P = .0001). In contrast, children with underlying chronic conditions had a higher risk of misdiagnosis (appropriate diagnosis OR, 0.19; 95% CI, 0.10-0.33). The mean time from the onset of symptoms to clinical diagnosis was 4.55 ± 2.2 days and to serological confirmation was 7.0 ± 3.4 days. CONCLUSIONS: Measles is frequently misdiagnosed in low-prevalence settings. Specific measures to increase pediatricians' awareness about vaccine-preventable infections need to be implemented.

BACKGROUND: Seasonal influenza in Health-Care Workers (HCWs) is a topic of growing interest in public health for its organizational implications. The study aims at measuring absenteeism due to influenza in HCWs of an Italian pediatric hospital. RESEARCH DESIGN AND METHODS: A retrospective observational study on absenteeism for influenza and influenza-like illness was carried out on all hospital HCWs. Sickness absences up to 5 days and vaccination status of HCWs were recorded during the last two years (2016/2017, 2017 /2018). Average sickness absenteeism rate in vaccinated and unvaccinated HCWs and total working days lost were estimated. Daily mean cost for HCW was calculated in order to define the non-vaccination costs. RESULTS: In this study, the authors analyzed the overlapping between the trend of weekly sickness absenteeism and the morbidity rate associated with influenza epidemics in adults living in the Lazio region, Italy. An excess of 0.38 (p = 0.03) and 0.46 (p = 0.01) of average days lost was recorded in unvaccinated HCWs in the 2016/2017 and 2017/2018 epidemic seasons. The total amount of days lost in unvaccinated HCWs is 1.485,4 with a total cost of 252.060,54. CONCLUSIONS: Seasonal influenza vaccination confirms its key role in preventing outbreaks of influenza and promoting HCWs health.

BACKGROUND: In recent years, new information has been acquired regarding the diagnosis, treatment and prevention of acute otitis media (AOM). The Italian Pediatric Society, therefore, decided to issue an update to the Italian Pediatric Society guidelines published in 2010. METHODS: The search was conducted on Pubmed, and only those studies regarding the pediatric age alone, in English or Italian, published between January 1, 2010 and December 31, 2018, were included. Each study included in the review was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology. The quality of the systematic reviews was evaluated using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 appraisal tool. The guidelines were formulated using the GRADE methodology by a multidisciplinary panel of experts. RESULTS: The importance of eliminating risk factors (passive smoking, environmental pollution, use of pacifier, obesity, limitation of day-care center attendance) and the promotion of breastfeeding and hygiene practices (nasal lavages) was confirmed. The importance of pneumococcal vaccination in the prevention of AOM was reiterated with regard to the prevention of both the first episode of AOM and recurrences. Grommets can be inserted in selected cases of recurrent AOM that did not respond to all other prevention strategies. Antibiotic prophylaxis is not recommended for the prevention of recurrent AOM, except in certain carefully selected cases. The use of complementary therapies, probiotics, xylitol and vitamin D is not recommended. CONCLUSIONS: The prevention of episodes of AOM requires the elimination of risk factors and pneumococcal and influenza vaccination. The use of other products such as probiotics and vitamin D is not supported by adequate evidence.

Despite relevant recommendations and evidences on the efficacy of influenza vaccination in health care workers (HCWs), vaccination coverage rates in Europe and Italy currently do not exceed 25%. Aim of the study is to measure the variations in vaccination coverage rates in an Italian pediatric hospital after a promotion campaign performed in the period Octoberâ»December 2017. The design is a pre-post intervention study. The intervention is based on a wide communication campaign and an expanded offer of easy vaccination on site. The study was carried out at Bambino Gesù Children’s hospital in Rome, Italy, on the whole population of HCWs. Univariate and multivariate statistical analyses were performed. Vaccination coverage rate increased in 2017/18 campaign compared with the 2016/17 one (+95 HCWs vaccinated; +4.4%). The highest increases were detected in males (+45.7%), youngest employees (+142.9%), mean age of employment (+175%), other HCWs (+209.1%), Emergency Area (+151.6%) and Imaging Diagnostic Department (+200.0%). At multivariate logistic regression, working in some departments and being nurses represents a higher risk of being unvaccinated. Although the vaccination coverage rate remained low, a continuous increase of the coverage rate and development of a different consciousness in HCWs was highlighted. The study significantly identified the target for future campaigns.

To evaluate the effects of switching from successful long-term protease inhibitor (PI)-based HAART to a three nucleoside reverse transcriptase inhibitor PI-sparing regimen, viral load quantification, HIV-specific lymphoproliferative assay and T-cell receptor (TCR) spectratyping were performed during 96 weeks of simplification follow-up in 19 HIV-infected children. Our data showed that simplification of therapeutic strategies acts positively on immune competence in HIV paediatric patients. Our children maintained viral suppression, increased lymphoproliferative responses and normalized TCRBV repertoire on the CD8 subset.

OBJECTIVE: To evaluate the longer-term utility of genotypic resistance testing in HIV-1-infected children with virological failure. METHODS: Children aged 3 months-18 years switching antiretroviral therapy (ART) with HIV-1 RNA > 2,000 copies/ml were randomized between genotypic testing (Virtual Phenotype) and no testing at baseline and subsequent virological failures. Children were followed to at least 96 weeks. RESULTS: One hundred and seventy eligible children, from 24 clinical centres in six countries, were randomized to resistance testing (n = 87) or no testing (n = 83) between June 2000-July 2003. At baseline, mean HIV-1 RNA and CD4+ T-cell percentage were 4.7 log10 copies/ml and 20%, respectively. Children had taken ART for a mean of 5 years; 24% had received all three classes, 53% nucleoside reverse transcriptase inhibitors (NRTIs)+protease inhibitors (PIs), 9% NRTIs+non-nucleoside reverse transcriptase inhibitors (NNRTIs) and 14% NRTIs only. There was no difference between the arms in the drug classes or the individual PIs/NNRTIs prescribed. However, 49% in the resistance test arm (RT) versus 19% in the no-test arm (NT) continued at least one NRTI from their failing regimen; 56% versus 19% were prescribed didanosine+stavudine as their NRTI backbone. Adjusting for baseline HIV-1 RNA, mean reductions in HIV-1 RNA at 48 weeks were 1.51 log10 copies/ml in the RT arm and 1.23 in the NT arm (P = 0.3); the difference between the arms was smaller at week 96 (RT: 1.50, NT: 1.47; P = 0.9). CONCLUSION: In this first paediatric trial of resistance testing, we observed a substantial difference in NRTI-prescribing behaviour across arms. However statistically significant evidence of a long-term virological or immunological benefit was not observed. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN14367816.

BACKGROUND: Invasive diseases (ID) caused by Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae), and Neisseria meningitidis are a major public health problem worldwide. Comprehensive data on the burden of bacteremia and ID in Italy, including data based on molecular techniques, are needed. METHODS: We conducted a prospective, multi-centre, hospital-based study (GSK study identifier: 111334) to assess the burden of bacteremia and ID among children less than five years old with a fever of 39 °C or greater. Study participation involved a single medical examination, collection of blood for polymerase chain reaction (PCR) and blood culture, and collection of an oropharyngeal swab for colonization analysis by PCR. RESULTS: Between May 2008 and June 2009, 4536 patients were screened, 944 were selected and 920 were enrolled in the study. There were 225 clinical diagnoses of ID, 9.8 % (22) of which were bacteremic. A diagnosis of sepsis was made for 38 cases, 5.3 % (2) of which were bacteremic. Among the 629 non-ID diagnoses, 1.6 % (10) were bacteremic. Among the 34 bacteremic cases, the most common diagnoses were community-acquired pneumonia (15/34), pleural effusion (4/34) and meningitis (4/34). S. pneumoniae was the most frequently detected bacteria among bacteremic cases (29/34) followed by H. influenzae (3/34). Ninety percent (27/30) of bacteremic patients with oropharyngeal swab results were colonized with the studied bacterial pathogens compared to 46.1 % (402/872) of non-bacteremic cases (p < 0.001). PCV7 (7-valent pneumococcal conjugate vaccine) vaccination was reported for 55.9 % (19/34) of bacteremic cases. S. pneumoniae serotypes were non-vaccine serotypes in children who had been vaccinated. Mean duration of hospitalization was longer for bacteremic cases versus non-bacteremic cases (13.6 versus 5.8 days). CONCLUSIONS: These results confirm that S. pneumoniae is one of the pathogens frequently responsible for invasive disease.

Shared transmission routes of HCV and HIV mean parenteral HIV/HCV coinfection still occurs, often in resource-limited settings. The extent to which coinfection and treatment impact on morbidity and mortality in HIV/HCV coinfected children remains unknown thus optimal management and treatment is difficult to achieve. Using data from a unique, large, prospective cohort of parenterally HIV/HCV coinfected children in Libya we determine the immunological, virological and clinical profiles of HIV/HCV coinfected children documenting the natural and treated history of parenterally acquired coinfection for the first time in such a large group. 160 parenterally HIV/HCV coinfected children were analysed. Thirty-three (21%) received antiretroviral treatment (ART) for HIV disease during follow-up. In children receiving ART, HIV RNA viral load decreased in two-thirds 6-12 months after initiation. 85% (17/20) experienced a positive immunological response to ART with a median increase in CD4 cell count z-score of 131%. Half had progressed to moderate or severe immunosuppression and/or moderate or severe clinical symptoms three years after infection. In those who progressed during follow-up, 85% had done so within three years of infection. Children progressing to moderate or severe immunosuppression and/or clinical symptoms were significantly more likely to be receiving ART. This novel investigation of the natural and treated history of parenterally HIV/HCV coinfected children in a large prospectively followed group demonstrates minimal clinical symptoms and immunosuppression to date, despite low prevalence of treatment, and a response to ART similar to vertically HIV-only infected children.
