Systemic inflammatory response in erderly patients following hernioplastical operation
The number of old and oldest old patients undergoing surgery of varying severity is increasing. Ageing is a process that changes the performances of most physiological systems and increases susceptibility to diseases and death; accordingly, host responses to surgical stress are altered with ageing and the occurrence of age-related increase in susceptibility to post-operative complications has been claimed. Twenty-four male patients undergoing Lichtenstein (LH) hernioplasty for unilateral inguinal hernia were included in this study and divided in two groups (Young and Old respectively), according to their age. As expression of the acute phase response, we measured changes in concentration of pro-inflammatory cytokines Tumor necrosis factor-α and Interleukin-1β, leukocytes, acute phase proteins C-reactive protein and α 1-antitrypsin. Elderly humans showed prolonged and strong inflammatory activity compared to younger subjects in response to surgical stress, indicating that the acute-phase response to surgical stress of elderly humans varies from that of the young, showing initial hyperactivity and a delayed termination of the response. Thus, the acute phase response to surgical stress is higher in old subjects, but the clinical significance of this remains unclear. It is not known whether a causal relationship exists between this stronger acute phase response and the increases in susceptibility to post-operative complications observed in aged patients
Validation of a Commercial Loop-Mediated Isothermal Amplification (LAMP) Assay for the Rapid Detection of Anisakis spp. DNA in Processed Fish Products
Parasites belonging to the Anisakis genera are organisms of interest for human health because they are responsible for the Anisakiasis zoonosis, caused by the ingestion of raw or undercooked fish. Furthermore, several authors have reported this parasite to be a relevant inducer of acute or chronic allergic diseases. In this work, a rapid commercial system based on Loop-Mediated Isothermal Amplification (LAMP) was optimised and validated for the sensitive and rapid detection of Anisakis spp. DNA in processed fish products. The specificity and sensitivity of the LAMP assay for processed fish samples experimentally infected with Anisakis spp. larvae and DNA were determined. The LAMP system proposed in this study was able to give positive amplification for all the processed fish samples artificially contaminated with Anisakis spp., giving sensitivity values equal to 100%. Specificity tests provided no amplification for the Contracaecum, Pseudoterranova, or Hysterothylacium genera and uninfected samples. The limit of detection (LOD) of the LAMP assay proposed was 102 times lower than the real-time PCR method compared. To the best of our knowledge, this is the first report regarding the application of the LAMP assay for the detection of Anisakis spp. in processed fish products. The results obtained indicate that the LAMP assay validated in this work could be a reliable, easy-to-use, and convenient tool for the rapid detection of Anisakis DNA in fish product inspection

The impact of puberty on the onset, frequency, location, and severity of attacks in hereditary angioedema due to C1-inhibitor deficiency: A survey from the Italian Network for Hereditary and Acquired Angioedema (ITACA)
IntroductionHereditary angioedema due to C1-inhibitor deficiency is influenced by hormonal factors, with a more severe course of disease in women. Our study aims to deepen the impact of puberty on onset, frequency, location and severity of attacks.MethodsRetrospective data were collected through a semi-structured questionnaire and shared by 10 Italian reference centers of the Italian Network for Hereditary and Acquired Angioedema (ITACA).ResultsThe proportion of symptomatic patients increased significantly after puberty (98.2% vs 83.9%, p=0.002 in males; 96.3% vs 68,4%, p<0.001 in females); the monthly mean of acute attacks was significantly higher after puberty, and this occurred both in females (median (IQR) = 0.41(2) in the three years before puberty vs 2(2.17) in the three years after, p<0.001) and in males (1(1.92) vs 1.25(1.56) respectively, p<0.001). The increase was greater in females. No significant differences were detected in attack location before and after puberty.DiscussionOverall, our study confirms previous reports on a more severe phenotype in the female gender. Puberty predisposes to increased numbers of angioedema attacks, in particular in female patients
A mild form of Familial Mediterranean Fever associated with a polymorphisms C.NT 1588,-69G>
Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease caused by mutation(s) in the Mediterranean fever (MEFV, pyrinmarenostrin) gene [1,2]. FMF is characterized by recurrent fever crises combined with serosal, synovial, or cutaneous inflammation and, in some individuals, by the eventual development, in the long-term, of systemic amyloidosis [3,4]. FMF mainly affects peoples living along eastern Mediterranean Sea (Turks, Sephardic Jews, Armenians) and it is not a rare disease in other Mediterranean areas such as Greeks, Italians and Iranians [4,6]. Until now, more than 304 sequence variants have been recorded [6]. In Italy M694V, V726A, M680I, M694I and E148Q are the most frequent FMF-associated mutations [7].
Here, we describe a recent case of mild FMF, characterized by all the clinical manifestations indicative of FMF described in the literature, according to Tei-Hashomer criteria [4] and by the analysis of MEFV gene, characterized by polymorphism c1588-69G>A. This is in agreement with previous our observations in a wider sample collected in the years. We are training to define the relations among gene mutations and clinical forms of FMF
The complex alteration in the network of IL-17-type cytokines in patients with hereditary angioedema
Hereditary angioedema (HAE) is a rare autosomic-dominant disorder characterized by a deficiency of C1 esterase inhibitor which causes episodic swellings of subcutaneous tissues, bowel walls and upper airways that are disabling and potentially life-threatening. We evaluated n = 17 patients with confirmed HAE diagnosis during attack and remission state and n = 19 healthy subjects. The samples were tested for a panel of IL (Interleukin)-17-type cytokines (IL-1\u3b2, IL-6, IL-10, granulocyte\u2013macrophage colony stimulating factor (GM-CSF), IL-17, IL-21, IL-22, IL-23) and transforming growth factor-beta (TGF-\u3b2) subtypes. Data indicate that there are variations of cytokine levels in HAE subjects comparing the condition during the crisis respect to the value in the remission phase, in particular type 17 signature cytokines are increased, whereas IL-23 is unmodified and TGF-\u3b23 is significantly reduced. When comparing healthy and HAE subjects in the remission state, we found a significant difference for IL-17, GM-CSF, IL-21, TGF-\u3b21 and TGF-\u3b22 cytokines. These results confirm and extend our previous findings indicating that in HAE there is operating an inflammatory activation process, which involves also T helper 17 (Th17) cytokines and TGF-\u3b2 isoforms, associated with localized angioedema attacks and characterized by elevated bradykinin levels
Refurbishment scenario to shift nearly net ZEBs towards net ZEB target: an Italian case study
Production of cytokines at the operation site
Background and aim: Cytokines are part of a family of molecules
involved in the initiation, control and termination of the events that occurs in
wound healing process. Aim of this study was to evaluate the production of
some cytokines [interleukin (IL)-6, IL-10, IL-1a, IL-1ra, interferon
(IFN)-g] in the drainage wound fluid from patients undergoing incisional
hernia repair.
Methods: Ten female patients with abdominal midline incisional hernia undergoing to surgical repair were included in this study. In all cases a
closed suction drain was placed in the wound below the fascia and it was
removed on the 4 th postoperative day. Wound fluid was collected on the 1st
,
2
nd, 3rd and 4th day and its amount in each time was recorded. The production of IL-6, IL-10, IL-1a, IL-1ra and IFN-g were evaluated as quantity
produced in 24 hour.
Results: In all patients the amount of drain fluid from surgical wound
was highest on the 1st day after surgery, afterwards there is a significant
reduction. The production of all cytokines evaluated was highest on the 1st
day decreasing on the 2nd day except for IL-1a that not show any modification. The produciton of IL-1ra, IL-6, IL-1a and IL-10 was significantly
reduced on the 3rd and 4th postoperative day in comparison with the respectively values recorded on the 1st day, whereas IFN-g levels were similar.
Conclusions: The dosage of cytokines in the drain fluid led us to better evaluated the events that follow surgical wound and their analysis offers
further information in the role of cytokines in healing process, with the goal to
get supportive treatments to promote the best evolution
