Atopic dermatitis and atopic march: which link?

There is a long standing debate on the atopic march in childhood. The natural progression of allergic manifestations may be considered as comorbidities, which occur more frequently in a specific evolutive age. On the other hand, the natural history of allergies in children may follow trajectories that may be heterogeneous. The effects of atopic march in clinical practice have also been reported

Activated phosphoinositide 3-dinase delta syndrome (APDS): An update

Activated phosphoinositide 3-kinase delta syndrome (APDS) is a recently described form of inborn error of immunity (IEI) caused by heterozygous mutations in PIK3CD or PIK3R1 genes, respectively, encoding leukocyte-restricted catalytic p110\u3b4 subunit and the ubiquitously expressed regulatory p85 \u3b1 subunit of the phosphoinositide 3-kinase \u3b4 (PI3K\u3b4). The first described patients with respiratory infections, hypogammaglobulinemia with normal to elevated IgM serum levels, lymphopenia, and lymphoproliferation. Since the original description, it is becoming evident that the onset of disease may be somewhat variable over time, both in terms of age at presentation and in terms of clinical and immunological complications. In many cases, patients are referred to various specialists such as hematologists, rheumatologists, gastroenterologists, and others, before an immunological evaluation is performed, leading to delay in diagnosis, which negatively affects their prognosis. The significant heterogeneity in the clinical and immunological features affecting APDS patients requires awareness among clinicians since good results with p110\u3b4 inhibitors have been reported, certainly ameliorating these patients\u2019 quality of life and prognosis

Vernal keratoconjunctivitis: state of art and update on treatment

Vernal keratocongiuntivitis (VKC) is a chronic inflammatory disease affecting the ocular conjunctiva and cornea. It is a rare and underestimated pathology, whose missed or delayed diagnosis can lead to the development of serious ocular complications. Moreover, despite VKC symptoms are well known, they can overlap and be mistaken with allergic conjunctivitis. In fact, diagnostic criteria and severity grading are not standardized yet. The pathogenesis of VKC is still controversial and it is difficult to identify a single mechanism underlying the chronic ocular inflammation. Different studies hypothesized both allergies and autoimmune diseases and also oxidative stress contribute significantly to the origin of the disease. However, the unclear pathogenesis and the lack of specific disease biomarkers make treatment a challenge. The standard therapy includes antihistamines, anti-inflammatory and immunosuppressant drugs and novel therapies are currently under investigation. However, considering treatment guidelines and recommendations are not well defined yet, therapy should be personalized on the clinical features of the patient. This paper provides an overview of the VKC and updates on the challenges that need to be addressed in the future to improve the management of the patient with this disease and improve his quality of life

Management of Malaria in Children Younger Than 5 Years Old During Coronavirus Disease 2019 Pandemic in Sierra Leone: A Lesson Learned?

Growing evidences are showing the potential indirect effects of the Coronavirus Disease 2019 (COVID-19) on the health systems of low-resource settings, where diseases such as Tuberculosis, Human Immunodeficiency Virus (HIV) and Malaria represent major killers. Therefore, we performed a retrospective study aimed to evaluate the impact of COVID-19 on Malaria programs in a peripheral region of Sierra Leone, previously involved by the Ebola outbreak in 2015, when malaria care have been impaired since local health systems were overwhelmed by Ebola cases. During COVID-19 in Sierra Leone, we did not notice a significant drop in malaria diagnosis in children, suggesting that a proactive approach in the management of malaria in endemic countries during COVID-19 may have had a positive impact. A comprehensive approach that include also educational activities to sensitize the local population, was useful to guarantee successful malaria diagnosis and treatment, and prevents excess of malaria deaths due to potential disruption of the local health systems related to the SARS-CoV-2 pandemic

Pilot study proposal on non-selective response to vaccination against HBV in children with juvenile idiopathic arthritis

The etiology of Juvenile Idiopathic Arthritis (JIA) is unknown though some correlations has been found with HLA genes. Since it is known that the immune response to HBV vaccine is largely determined by the presentation of the immunogenic peptides through HLA-DR and DQ molecules, it has been suggested that the presence of some of these haplotypes predisposes to a lower response to this vaccine. Some studies have found that patients affected by coeliac disease and type 1 diabetes mellitus have a less effective response to hepatitis B vaccination. The cause can probably be attributed to patients’ genetic predisposition or the inflammatory condition established if the coeliac patient doesn’t follow the correct gluten-free diet. In literature we found no studies on HBV vaccination response in patients affected by JIA. We hypothesized to lead a pilot study dosing the antibody titer against mandatory vaccines and lymphocyte activity after stimulation with HBV antigens in all our JIA patients, as well as performing immunological first level exams and HLA genes. Furthermore these same parameters will be studied in two groups of children similar in age and sex: a group of coeliac patients and an healthy control group. We casually found some of our patients affected by JIA without the necessary antibody against HBV, although it has been shown that this may not be correlated with the real ability of the immune system to react to HBV infection. This study may be useful to identify patients susceptible to HBV infection and to improve vaccinal policies

Point-of-care ultrasound (POCUS) in a remote area of Sierra Leone: impact on patient management and training program for community health officers

Purpose: Point-of-care ultrasound (POCUS) has been shown to have unique potential in low-income countries. Physicians and other healthcare providers can perform effective scans after a short period of training. This study aimed to evaluate indications and utility of ultrasonography as the main imaging service in a poor rural sub-Saharan region of Africa. Second, it evaluated the effect of a short training on POCUS for non-physician health providers and their agreement with a group of Italian physicians. Methods: This study was undertaken in Lokomasama—a chiefdom of Sierra Leone—between January and February 2019. Based on clinical indications, ultrasound findings were evaluated with respect to the initial diagnostic hypothesis. Volunteer doctors conducted a theoretical–practical training of two community health officers (CHO) on chest and abdominal POCUS and E-FAST protocol. The evaluation of the achieved technical skills was obtained with a numeric score. Inter-observer agreement concerning ultrasound diagnosis based on clinical indications was assessed. Results: A total of 196 consecutive patients underwent ultrasound examination. POCUS findings were in keeping with the clinical diagnosis in the 49.5%. POCUS changed the initial diagnosis in 17% of cases. After training, E-FAST and POCUS knowledge score was 90% and 83%, respectively. An excellent inter-observer agreement (0.88) was found between CHOs and physicians. Conclusion: POCUS represents a powerful diagnostic tool in a low-income country that may improve the patient management. Training of non-physician health providers is doable and may improve healthcare management in resource-limited settings
