Study summary

Diabetic nephropathy is one of the most common microvascular complications of diabetes mellitus and a leading cause of chronic kidney disease. Inflammation and platelet activation are believed to play a significant role in its pathogenesis and progression.

Developmental endothelial locus-1 (DEL-1) is an anti-inflammatory protein that regulates leukocyte adhesion and endothelial function, while thromboxane A2 is a marker of platelet activation and contributes to vascular dysfunction.

This study aims to evaluate serum levels of DEL-1 and thromboxane A2, and their relationship with platelet count in patients with diabetic nephropathy. Additionally, the study investigates the correlation between these biomarkers and disease severity.

This observational cross-sectional study will be conducted on 80 participants, including patients with diabetic nephropathy and healthy controls, to explore the potential role of these biomarkers in disease progression and their possible use as diagnostic or prognostic indicators.

Study population

The study population will include adult participants aged 18 to 70 years, recruited from Aswan University Hospital. The study will consist of patients diagnosed with diabetic nephropathy based on clinical and laboratory criteria, in addition to a group of age- and sex-matched healthy controls.

Patients with diabetic nephropathy will be enrolled regardless of disease stage to allow assessment of biomarker variation across different levels of disease severity. All participants will undergo clinical evaluation and laboratory investigations.

Participants with significant comorbid conditions that may affect inflammatory status or platelet function will be excluded to minimize confounding factors.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult patients aged between 18 and 70 years.
  • Patients diagnosed with diabetic nephropathy based on clinical and laboratory findings.
  • Patients undergoing evaluation or follow-up for diabetic kidney disease.
  • Ability and willingness to provide .

Exclusion criteria

Exclusion Criteria:

  • - Patients with known hepatic disease.
  • Patients with significant cardiovascular disease.
  • Patients with .
  • Patients who have undergone recent surgery.
  • Patients with known hematological disorders or hypercoagulable states.
  • Patients receiving medications that significantly affect function.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
