A Multicenter ICET-A Study on Age at Menarche and Menstrual Cycles in Patients with Transfusion-Dependent Thalassemia (TDT) who Started Early Chelation Therapy with Different Chelating Agents.

Introduction: To evaluate the effect of early chelation therapy (≤ 3 years) with a variety of chelating agents on age at menarche and menstrual characteristics in patients with transfusion-dependent thalassemia (TDT). Design: A retrospective multicenter study promoted by the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A). Setting: Eight of 13 International Thalassemia Centers (61.5%) in the ICET-A Network participated. Patients: Fifty-seven female TDT patients, aged 11 to 26 years, and with early iron chelation therapy, were eligible for the present study. They were enrolled from one center from Iran (33 patients), 3 centers from Bulgaria (9), 1 from Greece (8), one from Oman (4), 1 from Cyprus (2), and 1 from Italy (1). Seven patients were excluded, four still prepubertal (age 12-14 years) and 3 with primary amenorrhea. Therefore 50 patients were finally enrolled. Results: All fifty TDT patients developed spontaneous menarche at a mean age of 14.2 ± 2.24 years (range 9 - 20). A significant positive correlation was observed between age at menarche and serum ferritin levels (r: 0. 41, p=0.005). Regular menstrual cycles were reported from 32 (64%) patients, of whom 28 (83.3%) get menarche at age ≤ 14 years. Complications were more frequent in patients older than 14 years at menarche and in those with secondary amenorrhea. Conclusions: Age at menarche greater than 14 years was a forerunner of menstrual irregularities and associated complications in 36% of patients despite precocious chelation therapy. The poor adherence to treatment, to be demonstrated in future studies, could explain the finding.

Screening of COVID-19 in children admitted to the hospital for acute problems: preliminary data.

BACKGROUND: The new Coronavirus identified in Whuan at the end of 2019 (SARS-CoV-2) belongs to the Beta Coronavirus genus and is responsible for the new Coronavirus 2019 pandemia (COVID-19). Infected children may be asymptomatic or present fever, dry cough, fatigue or gastrointestinal symptoms. The CDC recommends that clinicians should decide to test patients based on the presence of signs and symptoms compatible with COVID-19. MATERIAL AND METHODS: 42 children (the majority < 5 years of age) were referred, to our Pediatric Department, as possible cases of COVID-19 infection. Blood analysis, chest X-ray, and naso-oropharyngeal swab specimens for viral identification of COVID-19 were requested. RESULTS: None of the screened children resulted positive for COVID-19 infection. At first presentation, the most frequent signs and symptoms were: fever (71.4%), fatigue (35.7%) and cough (30.9%).  An  high  C-reactive protein value and abnormalities of chest  X-ray (bronchial wall thickening) were detected in 26.2% and 19% of patients, respectively. Almost half of patients (45.2%) required hospitalization in our Pediatric Unit and one patient in Intensive Care Unit. CONCLUSIONS: Testing people who meet the COVID-19 suspected case definition criteria is essential for clinical management and outbreak control. Children of all ages can get COVID-19, although they appear to be affected less frequently than adults, as reported in our preliminary survey. Further studies are needed to confirm our observations.

Cutaneous toxicity from epidermal growth factor receptor inhibitors: would a subcutaneous desensitization be helpful? Case report.

PURPOSE: Cetuximab and panitumumab are monoclonal antibody inhibitors that bind the epidermal growth factor receptor (EGFR) currently used in the treatment of metastatic colorectal cancer. The main adverse event related to EGFR inhibitors (EGFR-Is) is cutaneous toxicity, which can cause dosage reduction and interruption of treatment. State-of-the-art management of skin toxicity associated with EGFR-Is therapy involves the topical administration of corticosteroids and oral antibiotics, but is not completely effective in the management of toxicity. Subcutaneous desensitization with increasing concentrations of monoclonal antibodies can induce a tolerance to drug administration and reduce cutaneous adverse effects. To our knowledge, this is the first case in which a reduction or a disappearance of skin toxicity caused by EGFR-Is through subcutaneous desensitization has been achieved. CASE REPORT: We present cases of 2 Caucasian patients with adenocarcinoma of the colon treated with EGFR-Is who developed severe cutaneous toxicity. A 73-year-old man presented grade 4 skin toxicity of the face and grade 3 skin toxicity of the trunk during treatment with cetuximab. A 68-year-old woman developed G2 rash on the face after the first administration of cetuximab. These patients underwent subcutaneous desensitization with increasing concentrations of EGFR-Is. After this procedure, patients restarted therapy at the optimal dosage with reduction or disappearance of skin toxicity. CONCLUSIONS: These cases suggest that by giving rising doses of antibody it is possible to obtain desensitization able to prevent severe cutaneous adverse events in patients treated with EGFR-Is.
