It included several groups of subjects: 31 overweight subjects; 91 obese adults divided into two subgroups according to the BMI value (BMI 30\u201335\u200aKg\/m2 and BMI\u200a&gt;\u200a35\u200aKg\/m\n                    <jats:sup>2<\/jats:sup>\n                    ); 90 subjects with metabolic syndrome (MS) divided into two subgroups (with and without diabetes mellitus); 100 subjects with preclinical carotid atherosclerosis (PCA) divided according to the number of cardiovascular risk factors and to the insulin resistance degree; 48 subjects with obstructive sleep apnoea syndrome (OSAS) divided according to the apnoea\/hypopnea index (AHI); 27 subjects with chronic kidney disease (CKD) on conservative management; 31 subjects with CKD on regular haemodialysis treatment. We have found a significant increase of MMP-9 and TIMP-1 in overweight subjects, in obese adult and in MS subjects. In obese adults, the behaviour of these two parameters was not influenced by the degree of obesity, while in the group of MS subjects both these parameters were clearly influenced by the presence of diabetes mellitus. In subjects with PCA, we observed an increase of MMP-9 associated with a significant decrease of TIMP-1; the same trend was found by subdividing the entire group in accordance with the number of cardiovascular risk factors and with the insulin resistance degree. In subjects with OSAS, we noted an increase in MMP-9 and TIMP-1; this increase was more evident in subjects with OSAS having AHI\u200a&gt;\u200a30. In individuals with CKD on conservative and haemodialysis treatment we have found, at baseline, a marked increase in MMP-9 and a significant decrease of TIMP-1. In dialyzed subjects, after a standard dialysis session was noted, a significant increase in MMP-9 was associated with a further decrease in TIMP-1.\n                  <\/jats:p>","DOI":"10.3233\/ch-201094","type":"journal-article","created":{"date-parts":[[2021,4,2]],"date-time":"2021-04-02T14:37:11Z","timestamp":1617374231000},"page":"401-416","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["The function of matrix metalloproteinase-9 (MMP-9) and its tissue inhibitor (TIMP-1) in several clinical conditions: Results and analysis of our survey"],"prefix":"10.1177","volume":"78","author":[{"given":"Gregorio","family":"Caimi","sequence":"first","affiliation":[{"name":"Department of Health Promotion, Mother and Child Care, Internal Medicine and Medical Specialties, Universit\u00e1 degli Studi di Palermo, Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eugenia","family":"Hopps","sequence":"additional","affiliation":[{"name":"Department of Health Promotion, Mother and Child Care, Internal Medicine and Medical Specialties, Universit\u00e1 degli Studi di Palermo, Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Montana","sequence":"additional","affiliation":[{"name":"Department of Health Promotion, Mother and Child Care, Internal Medicine and Medical Specialties, Universit\u00e1 degli Studi di Palermo, Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caterina","family":"Urso","sequence":"additional","affiliation":[{"name":"Fondazione Istituto \u201cG.
