Endometrial metastasis of lung adenocarcinoma: a case report.

The female genital tract is an infrequent site of metastasis, in particular from extragenital primary tumors such as non-small cell lung cancer. Ovarian metastases have been described as disseminations of lung adenocarcinoma; rare cases of secondary localizations in adnexa, cervix and vagina were also observed in the literature, but none of these had endometrial involvement. We report the first case, to our knowledge, of non-small cell lung cancer with metastatic spread to the endometrium.

Typhlitis during second-line chemotherapy with pemetrexed in non-small cell lung cancer (NSCLC): A case report.

Neutropenic enterocolitis, or typhlitis, is an unusual acute complication of chemotherapy-induced neutropenia, characterized by inflammatory process involving colon and/or small bowel that may progress to necrosis, haemorrhage, perforation and septicaemia. Typhlitis is usually seen in the setting of severe chemotherapy-induced neutropenia for acute leukaemia. Nevertheless, it is increasingly recognized as a complication of therapy in solid tumors.

Ability of epistatic interactions of cytokine single-nucleotide polymorphisms to predict susceptibility to disease subsets in systemic sclerosis patients.

Objective: Gene-gene interaction, or epistasis, is considered a ubiquitous component of complex human diseases such as systemic sclerosis (SSc). Epistasis is difficult to model by traditional parametric approaches; therefore, nonparametric computational algorithms, such as multifactor dimensionality reduction (MDR), have been developed.

Methods: A total of 242 consecutive unrelated Italian SSc patients and an equal number of well-matched healthy controls were genotyped for 22 cytokine single-nucleotide polymorphisms (SNPs; 13 cytokine genes).

Interleukin-1 gene complex polymorphisms in systemic sclerosis patients with severe restrictive lung physiology.

Increased concentrations of interleukin-1 (IL-1) were observed in bronchoalveolar lavage fluids from patients with systemic sclerosis (SSc), and their levels were correlated with the patients' forced vital capacity (FVC). Because IL-1 production is regulated at the genetic level, we hypothesized that IL-1 gene complex single nucleotide polymorphisms (SNPs) might be relevant to the progression of ventilatory restriction in SSc. Two-hundred four Italian SSc patients were genotyped for the following IL-1 gene complex SNPs: IL-1alpha C-889T, IL-1beta C+3962T, IL-1beta C-511T, IL-1R Cpst1970T, and IL-1Ra Cmspal11100T, as well as for the following SNPs of cytokines with regulatory functions on IL-1 production: IFNgamma AUTR5644T, TNFalpha A-308G, and IL-10 A-1082G.

Proximal interleukin-10 gene polymorphisms in Italian patients with systemic sclerosis.

Interleukin-10 (IL-10) can favour the development of fibrosis by promoting a relative shift towards T helper 2 responses. Three single base pair substitutions in the 5' flanking region of the IL-10 gene (G/A -1082, C/T -819 and C/A -592) influence the amount of IL-10 secreted in cell cultures: the GCC haplotype is associated with an increased production, while the ACC and the ATA haplotypes are associated with intermediate and decreased production. Accordingly, three phenotypes have been individuated: high producers (GCC+/GCC+), medium producers (GCC+/GCC-) and low producers (GCC-/GCC-).

T-889C IL-1alpha promoter polymorphism influences the response to oral cyclophosphamide in scleroderma patients with alveolitis.

Cyclophosphamide (CYC) is the cornerstone of the treatment of systemic sclerosis (SSc)-associated fibrosing alveolitis (FAS). Despite treatment with CYC, in a not negligible proportion of SSc-FAS patients, deterioration in lung function can be observed. Interleukin-1 (IL-1) cluster gene single nucleotide polymorphisms (SNPs) were implicated in the pathogenesis of some interstitial lung diseases and may favor the progression of restrictive lung disease in SSc.

HLA class II antigens associated with lupus nephritis in Italian SLE patients.

Human leukocyte antigen DR2 (HLA-DR2), namely the allelic variant HLA-DR15, have been associated with lupus nephritis (LN) in Caucasians. The study investigated the relationships between HLA class II alleles and lupus nephritis in Italian patients. Two hundred forty-four patients fulfilling the American Rheumatism Association criteria for systemic lupus erythematosus (SLE) were typed for HLA-DRB1*, -DQA1*, -DQB1*, and -DPB1* alleles by polymerase chain reaction-sequence-specific oligonucleotide and polymears chain reaction-single-strand polymorphism; 71 patients had renal damage assessed by renal biopsy.

Anti-thyroid antibodies in Italian scleroderma patients: association of anti-thyroid peroxidase (anti-TPO) antibodies with HLA-DR15.

Objective: To evaluate the frequency of anti-thyroid antibodies in a group of patients with scleroderma (SSc) and to analyze their genetic association with the HLA class II antigens.

Methods: Anti-thyroglobulin (anti-TG) and anti-thyroid peroxidase (anti-TPO) antibodies were measured by hemagglutination techniques. Thyroid function was evaluated by determining the levels of FT3, FT4 and TSH.
