Ragweed pollen is an important component of biological pollution in the urban environment, responsible for increasing respiratory allergies and significant contribution to the health impact of air pollution in the Bucharest area. The aim of this paper is to present the eight-year ragweed pollen monitoring data from Bucharest, to place them in the context of local air pollution, public health regulations and available data on the health impact of ragweed pollen in the urban environment. Our pollen data were correlated with major air pollutant concentrations and with meteorological factors in a recently published local paper and the clinical data of patients with ragweed-induced respiratory symptoms were collected and published in 2019.

Eosinophilic gastroenteritis (EGE) is a subgroup of the eosinophilic gastro-intestinal disorders (EGIDs), characterized by eosinophilic infiltration and chronic inflammation of the gastrointestinal tract. These are rare diseases with still incompletely elucidated causes and mechanisms, with frequently delayed diagnosis and variable outcome. Despite increased interest in eosinophilic diseases in recent years, fewer data have been published on EGE and no standardized diagnostic and therapeutic approach exists.

Introduction Vaccination is the most important confirmed tool that can stop the ongoing coronavirus disease 2019 (COVID-19) pandemic, but the vaccination rate remains low in some countries, including Romania, despite consistent and undoubtedly scientific proof of this disease-prevention method. The risk of allergic reactions after COVID-19 vaccines may be a reasonable cause for the antivaccination attitude of people with a history of allergies or who consider themselves at risk for having severe allergic reactions after vaccination. Objective Our paper aims to analyze the role of allergist advice in getting people with a history of allergies to trust and accept COVID-19 vaccines and to evaluate the real risk of allergic reactions to these vaccines in this population.

Mast cells are granulocytic immunomodulatory cells with an important role in physiologic and pathogenic processes due to their location at the junction between the internal and external environment and to their capacity to release a broad range of active mediators. Mast cells mediators have both pro-inflammatory and anti-inflammatory activities and are implicated in various and complex pathology. Mast cells disorders (MCDs) represent a heterogeneous pathology, with frequently difficult and challenging evaluation and diagnostic workup.

Biologic therapy is recommended by Global Initiative for Asthma (GINA) guidelines in asthma patients not controlled with maximal inhaled therapy corresponding to GINA step 4. Omalizumab is an anti- immunoglobulin E (IgE) monoclonal antibody and the first biological available for the add-on treatment of severe allergic asthma, approved by Food and Drug Administration (FDA) in 2003. Diagnosing and managing asthma patients during coronavirus disease 2019 (COVID-19) pandemic since early 2020 has been challenging, mainly due to the risk of contracting COVID-19 disease and to the limited access to hospital care and pulmonary function tests.

According to recent data, psoriatic patients have an increased prevalence of non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome, compared with the general population. In some published studies, the severity and presence of psoriasis disease were correlated with the severity of NAFLD. In the current study, we aimed to compare the sensibility and specificity of the non-invasive scores and liver biopsy in determining fibrosis in patients with NAFLD and moderate to severe psoriasis.

Mast cell activation syndromes (MCAS) represent a heterogeneous clinical entity caused by episodic and severe mast cell activation, including primary and secondary mast cell disorders (MCDs). The group of primary or clonal MCDs refers to systemic mastocytosis, other clonal MCAS and hereditary hypertryptasemia, while the secondary MCAS is characterized by normal mast cells (MCs) which are activated by external triggers, such as allergens or physical stimuli. Another category of MCAS is the idiopathic form, when no trigger or genetic mutation can be identified.

Angiotensin-converting enzyme inhibitors (ACEIs) represent an important group of pharmacological compounds, largely prescribed for more than 30 years. They have been extensively evaluated in clinical trials, demonstrating significant reduction of morbidity and mortality of patients with cardiovascular diseases, mainly high blood pressure, myocardial infarction, heart failure and stroke. Besides their beneficial effects and a general good safety profile, it was proven that ACEIs might also induce adverse effects in some patients, most notably angioedema (AE) and chronic cough.

Eosinophilic disorders represent a group of pathologic conditions with highly heterogeneous pathophysiology and clinical presentation and variable prognosis, ranging from asymptomatic or mild, to severe and complex cases, with fatal outcome. Interest in this group of disorders has increased during the last two decades, with consistent progress made regarding understanding of molecular mechanisms, refining of diagnostic criteria, classification and evaluation of therapeutic options. There are still many gaps and difficulties in evaluating eosinophilic syndromes and diseases in medical practice.

Eosinophils are innate immune leukocytes recruited in large numbers to sites of allergic inflammation and parasitic infections. Recent studies show additional pleiotropic effects of recruited eosinophils impacting immunomodulation, tissue homeostasis and repair. Pathologic conditions accompanied by blood eosinophilia are quite frequent in medical practice and may raise serious differential diagnosis problems in severe cases, that require a multidisciplinary approach.

Allergic diseases represent an important health problem in the most of developed countries, due to continuous increasing prevalence, with significant individual and social consequences. Allergic diseases may raise serious problems in clinical practice, derived from complexity of clinical forms and mechanisms and from rising incidence of severe cases, with high fatality risk. Taking into consideration the dramatic increase of all allergies forms during the last decades, they are considered a real "epidemic" of the XXIst century, being classified by the World Health Organization as the fourth most frequent chronic diseases.
