About this study

Official title: Klotho and Bone Mineral Density (BMD) in Systemic Sclerosis Patients: Relationship with Microvascular Damage and Fibrosis

The present study recruits female patients aged 45-65 years with a diagnosis of Systemic Sclerosis according to the EULAR/ACR 2013 criteria and age and gender-matched healthy control subjects. The purpose of the study is to investigate the possible role of Klotho and other cytokines involved in the osteoimmunological control of bone turnover as a possible determinant of the microvascular damage and fibrosis observed in SSc patients

Read the detailed description

The present study recruits female patients aged 45-65 years with a diagnosis of Systemic Sclerosis according to the EULAR/ACR 2013 criteria and age and gender-matched healthy control subjects. The purpose of the study is to investigate the possible role of Klotho and other cytokines involved in the osteoimmunological control of bone turnover as a possible determinant of the microvascular damage and fibrosis observed in SSc patients . For each patient demographic data, history of fractures and smoking habits will be gathered. Evaluation of bone mineral density will be performed and blood samples to dose DDK1, sclerostin, osteoprotegerin and Klotho will be collected.

Being tested
Possible Klotho effects on SSc clinical conditions, namely skeletal, fibrotic and microangiopathic damage, Evalution in healthy patients of bone mineral density, Klotho level and key bone-related cytokines
Medical subject headings
Scleroderma, Systemic

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Possible Klotho effects on SSc clinical conditions, namely skeletal, fibrotic and microangiopathic damageOther

    Female patients with a diagnosis of Systemic Sclerosis ( EULAR/ACR 2013 criteria ) attending the FPG Department of Rheumatology will be recruited after exclusion criteria are ruled out and informed consent is signed. DXA bone mineral density determination (Lunar Prodigy ) will be performed and bone metabolism parameters, according to routinary clinical practice, will be collected. Immunological and SSc-related disease features will also be recorded. Fibrosis will be determined by the extent of cutaneous involvement (limited or diffuse) and modified Rodnan Skin Score. Microangiopathy will be assessed by videocapillaroscopy and presence of acral ulcers or acrosteolysis; Presence of calcinosis will also be assessed .

    Upon recruitment each SSc patient will undergo blood sampling, which will be centrifuged and stored at -80° until the day of the processing. Biomarkers (Klotho, OPG, DKK, and sclerostin) will be determined using commercial kit of the ELISA Immunoenzyme techniques

  • Evalution in healthy patients of bone mineral density, Klotho level and key bone-related cytokinesOther

    Healthy female control patients undergoing bone mineral density determination will be recruited upon exclusion criteria are ruled out. A detailed clinical history will be assessed and blood sempling will be processed for detection of bone-related cytokines

Study groups in NCT05777954
Study groupRoleWhat they receive
Systemic Sclerosis patientsFemale patients with systemic sclerosis with an age between 45 and 65 years old and did not met the exclusion criteria. Blood sample were collected to determine DKK1, Sclerostin Klotho and Osteoprotegerin. Bone mineral density was assessed. No drug was tested during the study.
Receives: Other: Possible Klotho effects on SSc clinical conditions, namely skeletal, fibrotic and microangiopathic damage
Healthy subjectsFemale patients with no history of inflammatory rheumatic disease and who di not met the exclusion criteria. Blood sample were collected to determine DKK1, Sclerostin Klotho and Osteoprotegerin. Bone mineral density was assessed. No drug was tested during the study.
Receives: Other: Evalution in healthy patients of bone mineral density, Klotho level and key bone-related cytokines

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment of Klotho serum levels in a group of 63 female SSc patients aged 45-65 years compared to 63 age and sex-matched healthy controls

    Klotho serum levels in each SSc and control subject will be determined by a commercial ELISA assay

    Measured: 21 months

Secondary outcomes (3)
  1. Klotho serum levels in female SSc patients: relationship to microvascular damage and fibrosis

    Evaluation of a possible relationship among Klotho serum levels, the extent and type of the microvascular damage assessed by videocapillaroscopy, and the extent of the cutaneous fibrotic involvement assessed by the modified Rodnan skin score (mRSS).

    Measured: 21 months

  2. Klotho serum levels in female SSc patients: relationship to bone mineral density values

    Detection of a possible relationship between Klotho serum levels and bone mineral density values in female SSc patients stratified according to the extent of vascular and fibrotic damage

    Measured: 21 months

  3. Klotho serum levels in female SSc patients relationship to key bone-related cytokine serum levels

    Assessment of a possible relationship among Klotho, DDK-1, OPG, and sclerostin serum levels

    Measured: 21 months

Questions about this trial

What is this clinical trial studying?

An observational study of Systemic Sclerosis, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of Klotho serum levels in a group of 63 female SSc patients aged 45-65 years compared to 63 age and sex-matched healthy controls (time frame: 21 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2025.
