Qualitative and quantitative phytochemical analysis of different extracts from Thymus algeriensis aerial parts
This study was performed to evaluate the metabolite recovery from different extraction
methods applied to Thymus algeriensis aerial parts. A high-performance liquid chromatographic
method using photodiode array detector with gradient elution has been developed and validated
for the simultaneous estimation of different phenolic compounds in the extracts and in their
corresponding purified fractions. The experimental results show that microwave-assisted aqueous
extraction for 15 min at 100 C gave the most phenolics-enriched extract, reducing extraction
time without degradation effects on bioactives. Sixteen compounds were identified in this extract,
11 phenolic compounds and five flavonoids, all known for their biological activities. Color analysis
and determination of chlorophylls and carotenoids implemented the knowledge of the chemical
profile of this plant
Common Variable Immunodeficiency in Elderly Patients: A Long-Term Clinical Experience
none7siAbstract: Background: Common variable immunodeficiency (CVID) is a complex, predominantly
antibody deficiency usually diagnosed between 20–40 years. Few data about elderly patients are
reported in the literature. Our aim was to evaluate the clinical phenotypes of elderly patients with
CVID. Method: A retrospective analysis of adult patients with CVID was performed in our Referral
Centre, focusing on the main differences between “older” patients (≥65 years at the diagnosis) and
“younger” patients (<65 years). Results: The data from 65 younger and 13 older patients followed
up for a median period of 8.5 years were available. At diagnosis, recurrent infections represented
the only clinical manifestation in 61% and 69% of younger and older patients, respectively. The
incidence of autoimmune diseases was higher in elderly patients compared with younger ones (30 vs.
18%, respectively). During the follow-up, the incidence of autoimmune disorders and enteropathy
increased in the younger patients whereas neoplasia became the most prevalent complication in
the elderly (38%). All patients received a replacement therapy with immunoglobulin, with good
compliance. Conclusion: CVID occurrence in elderly patients is rarely described; therefore, the
clinical characteristics are not completely known. In our series, neoplasia became the most prevalent
complication in the elderly during the follow-up. In elderly patients, 20% SCIg was as safe as in
the younger ones, with good compliance. A genetic analysis is important to confirm the diagnosis,
identify specific presentations in the different ages, clarify the prognosis and guide the treatment.
Future clinical research in this field may potentially help to guide their care.openDanieli, Maria Giovanna; Mezzanotte, Cristina; Verga, Jacopo Umberto; Menghini, Denise; Pedini, Veronica; Bilò, Maria Beatrice; Moroncini, GianlucaDanieli, Maria Giovanna; Mezzanotte, Cristina; Verga, Jacopo Umberto; Menghini, Denise; Pedini, Veronica; Bilò, Maria Beatrice; Moroncini, Gianluc
La scelta della maternità. Una guida alla decisione per le donne con LES
La decisione di affrontare una gravidanza riguarda la scelta se avere o no un bambino o se avere un altro bambino, per chi già ne ha uno o più di uno. Prendere questa decisione è importante per ogni donna; dopo la diagnosi di LES, diventa più difficile. Va ricordato il rischio per la salute della madre durante la gravidanza e dopo il parto, così come va considerata la capacità per la madre di essere fisicamente in grado di prendersi cura del proprio figlio nel tempo. Valutare questi rischi fa parte delle gioie e delle preoccupazioni del diventare genitori. Questo libro ha lo scopo di fornire informazioni sui rischi e i benefici
che investono chi, portatore di LES, vuole affrontare una gravidanza e diventare genitore. Vuole aiutare la donna e il partner a prendere una
decisione informata

High-dose Facilitated subcutaneous Immunoglobulin in a Patient with refractory Polymyositis and severe Interstitial Lung disease
A Case of CVID-Associated Inflammatory Bowel Disease with CTLA-4 Mutation Treated with Abatacept
CTLA-4 (cytotoxic T-lymphocyte-associated protein 4) deficiency is a widely known cause of
immunodeficiency and autoimmunity, determining an immune dysregulation syndrome. We here present the case of
a Caucasian woman with common variable immunodeficiency (CVID) and severe enteropathy secondary to CTLA4 deficiency, successfully treated with abatacept.
Case Report: A 54-year-old woman affected by CVID, treated with 20%subcutaneous immunoglobulin, came to
our attention for chronic diarrhoea, severe malabsorption and significant weight loss, requiring parenteral nutrition.
Her past clinical history comprised psoriatic arthritis, idiopathic thrombocytopenic purpura and multifactorial
anemia. She started treatment with glucocorticoids and adalimumab, with partial benefit. However, after six months
anti-TNF-alpha agent was withdrawn for recurrent serious infectious episodes. Due to the complex phenotype, we
performed a genetic analysis, which revealed the presence of a CTLA-4 heterozygous mutation, with consequent
CTLA-4 deficiency. We decided therefore to start abatacept, a CTLA-4 fusion protein, at the dose of 125 mg/week
subcutaneously in association with budesonide, with improvement. At one year of follow-up diarrhea is still in
remission and the patient has gained weight. Even cutaneous lesions improved, whereas we documented only a
partial benefit for peripheral arthritis. CVID could present with complicated phenotype and immune dysregulation, underlying a more
complex syndrome, like CTLA-4 deficiency, thus suggesting the importance of genetic investigations in selected
patients. Abatacept is a potential effective treatment in patients with documented CTLA-4 deficiency, in particular
to induce and maintain remission of enteropathy
