"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Introduction: Diabetes Mellitus is a prothrombotic state characterised by enhanced platelet activity, which may lead to microvascular and macrovascular complications. Platelet indices, such as Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW), are routinely available in laboratories and can serve as a prognostic markers for patients.

Aim: To evaluate platelet indices in patients with Type 2 Diabetes Mellitus (T2DM) and associated complications.

Materials and Methods: A cross-sectional study was conducted at the Department of Pathology in Krishna Vishva Vidyapeeth’s Krishna Hospital and Medical Research Centre, Karad, Maharashtra, India, from July 2020 to May 2022. A total of 120 patients with type 2 diabetes, both with and without complications, were investigated. Haematological parameters (platelet count and platelet indices such as MPV and PDW) and biochemical parameters {fasting blood sugar and Haemoglobin A1c (HbA1c)} were compared between the two groups. Platelet indices were measured using an automated haematology analyser. Statistical analysis was performed using the t-test, Analysis of Variance (ANOVA), and Statistical Package for Social Sciences (SPSS) version 16.0.

Results: The study included 60 cases each of DM with complications and without. Among those with complications, 17 (28.33%) were aged 51-60 years, 14 (23.33%) were 61-70 years old, and 12 (20%) were over 70 years. The mean MPV was 12.74±3.076 fL for patients with complications and 8.65±1.58 fL for those without. The mean PDW was 15.54 15.54±3.31 fL for patients with complications and 13.94±2.66 for those without. The mean HbA1c levels were 8.33 mmol/mol for patients with complications and 6.75 mmol/mol for those without. The mean platelet count was 3.12 lakh/mm3 for patients with complications and 2.45 lakh/mm3 for those without. The mean fasting blood sugar levels were 219.65 mmol/L for patients with complications and 109.96 mmol/L for those without.

Conclusion: Diabetes contributes to endothelial dysfunction and platelet hyperactivity. The present study reveals that diabetic patients with uncontrolled glycaemic indices and elevated fasting blood sugar levels have higher platelet indices compared to patients without complications, where the platelet count, platelet indices, and glycaemic indices were within normal limits. These indices may also serve as useful prognostic tools.

Keywords

Diabetes mellitus, Prognostic marker, Vascular complications

Diabetes mellitus is a group of metabolic disorders characterised by hyperglycaemia, resulting from defects in insulin secretion, insulin action, or both. It is a leading cause of end-stage renal disease, adult-onset blindness, and non traumatic lower extremity amputations. Currently, the prevalence of diabetes among Indian adults is estimated at 8.8% (1),(2).

The complications associated with T2DM are primarily due to suboptimal glycometabolic control. Fasting Blood Glucose (FBG) and HbA1c are widely used to monitor glycometabolic control, with HbA1c reflecting the mean blood glucose levels over a three-month period. Factors contributing to diabetic complications include altered platelet morphology, increased platelet dysfunction, and reactivity, leading to a prothrombotic state and consequent vascular complications, which increase morbidity and mortality in diabetic patients (3),(4).

Platelets in DM are hyperactive, releasing more granules, leading to increased platelet turnover and the release of large, enzymatically and metabolically active platelets with a greater tendency to form clots, resulting in both macro and microvascular complications (4),(5).

Platelet indices are measured using automated haematology analysers (Nihon Kohden) as part of routine haematological procedures (6). The normal range for MPV in the laboratory is between 7.4-10.4 fL, and for PDW, it is 9-14 fL. MPV indicates the average size and activity of platelets and is calculated by dividing the Platelet Crit (PCT) by the platelet count. PDW measures the variability in platelet size and is calculated by determining the width of the platelet histogram at the 20% height level. PDW typically elevates earlier than other indices (7),(8). The present study investigates the effects of long-standing diabetes on complications and emphasises platelet function. The objectives of the study were to analyse the distribution of platelet indices in DM patients with and without complications and to compare the levels of HbA1c and FBS in complicated and uncomplicated cases of DM.

Material and Methods

This cross-sectional study was conducted in the Department of Pathology, Krishna Vishwa Vidyapeeth, Karad, Maharashtra, India, with data collected over a 24-month period (July 2020 to May 2022). Blood samples were collected into K2 Ethylenediaminetetraacetic Acid (EDTA) tubes, and platelet parameters were measured within one hour after venipuncture to avoid in-vitro changes. Parameters included MPV, PDW, platelet count, FBS, and HbA1c levels, with HbA1c categorised as <7.5, 7.5 to 10, and >10 mmol/L. The study aimed to compare platelet values and HbA1c between diabetic patients with and without complications and to note the presence of microvascular (diabetic retinopathy, chronic kidney injury, and acute kidney injury) and macrovascular complications (stroke, myocardial infarction, gangrenous toe, and peripheral vasculopathy). The study protocol was approved by the Institutional Ethics Committee (Protocol Reference number KIMS/030/2020-21).

Inclusion criteria: Patients with T2DM, both with and without complications such as stroke, myocardial infarction, acute kidney injury, chronic kidney injury, gangrenous toe, diabetic nephropathy, and peripheral vasculopathy were included in the study.

Exclusion criteria: Patients with systemic diseases in addition to DM, such as hypertension, systemic lupus erythematosus, rheumatoid arthritis, those on corticosteroids or antiplatelet drugs like aspirin, patients with Cushing syndrome, and those with any diagnosed malignancy were excluded from the study.

Normal range was considered as following: MPV: 7.4-10.4 fL, PDW: 9-14 fL, FBS: <100 mg/dL, HbA1c: <6.5% (7).

Study Procedure

Methodology involved the collection of blood into K2 EDTA tubes, with platelet parameters measured within one hour postvenipuncture to minimise the risk of platelet swelling. Blood specimens were gently mixed five times before a full blood count was measured using an automated blood analyser (Nihon Kohden). Given the heterogeneity in the volume and structure of platelets, the following haematological parameters were analysed in all blood samples: platelet count, MPV, PDW, and the biochemical parameters FBS and HbA1c.

Statistical Analysis

Statistical analysis was performed using SPSS version 16.0. Qualitative data were described as numbers and percentages. Quantitative data were presented as ranges (maximum and minimum), means, and Standard Deviations (SD). Comparisons between different groups regarding categorical variables were performed using the Student’s t-test. A p-value (probability) of <0.05 was considered statistically significant.

Results

Age distribution of DM with and without complications: The present cross-sectional study was conducted over a period of two years. Among the total number of cases of DM with complications, 17 (28.33%) of 60 patients were in the age group of 51-60 years, 14 (23.33%) of 60 belonged to the age group of 61-70 years, and 12 (20%) of 60 were older than 70 years of age. In patients with DM without complications, 21 (35%) of 60 patients were between the ages of 51-60 years, 5 (8.33%) of 60 were in the age group of 61-70 years, and 8 (13.3%) of 60 were older than 70 years of age (Table/Fig 1).

Gender-wise distribution: In DM with complications, out of 60 (100%) patients, 39 (65%) were male and 21 (35%) were female. In DM without complications, out of 60 (100%) patients, 37 (61.67%) were male and 23 (38.33%) were female. Both groups showed a nearly equal number of males and females, so the Chi-square test was used, and it was found that the p-value was not significant (p>0.05).

Comparing platelet indices with HbA1c levels in patients of DM and complications: The MPV was 11.95±2.55 for HbA1c <7.5 (n=21), 12.20±2.88 for HbA1c between 7.5 and 10 (n=29), and 15.91±3.35 for HbA1c >10 (n=10). The mean PDW was 15.10±1.56 for HbA1c <7.5, 16.08±2.11 for HbA1c between 7.5 and 10, and 17.00±1.99 for HbA1c >10. The mean platelet count was 2.93 lac/mm3±1.11 lac/mm3 for HbA1c <7.5, 3.54 lac/mm3±1.12 lac/mm3 for HbA1c between 7.5 and 10, and 3.67 lac/mm3±1.14 lac/mm3 for HbA1c >10 (Table/Fig 2).

Comparing platelet indices in DM without complications: The MPV for DM without complications was 8.63±1.51 for HbA1c <7.5 and 8.83±2.05 for HbA1c between 7.5 and 10. The mean PDW for DM without complications was 13.88±2.77 for HbA1c <7.5 and 14.23±2.09 for HbA1c between 7.5 and 10. The mean platelet count for DM without complications was 2.48 lac/mm3±83,398 for HbA1c <7.5 and 2.25 lac/mm3±78,757 for HbA1c between 7.5 and 10 (Table/Fig 3).

Comparison of HbA1c and FBS in diabetic patients with and without complications: The mean HbA1c was 8.33±1.45 for diabetes with complications and 6.75±0.61 for diabetes without complications. The mean FBS was 219.65±101.32 for diabetes with complications and 109.96±26.17 for diabetes without complications (Table/Fig 4).

Comparison of platelet indices and platelet count in patients of DM with complications: The mean platelet count for stroke patients was 2.97±1.022 lac/mm3, for Myocardial Infarction (MI) it was 2.0 lac/mm3±64500, for Acute Kidney Injury (AKI) it was 4.09±1.15 lac/mm3, for Chronic Kidney Injury (CKI) it was 2.71 lac/mm3±69429 for gangrene toe it was 3.70 lac/mm3±1.13 lac/mm3, for diabetic retinopathy it was 3.52 lac/mm3±1.07 lac/mm3, and for peripheral vasculopathy, it was 3.19 lac/mm3±58174 mm3. The mean Platelet Distribution Width (PDW) was 13.48±3.28 fL for stroke, 12.05±1.27 fL for MI, 13.78±1.38 fL for AKI, 14.05±2.29 fL for CKI, 14.8±3.15 fL for gangrenous toe, 14.1±3.31 fL for diabetic retinopathy, and 11.86±1.067 fL for peripheral vasculopathy. The Mean Platelet Volume (MPV) was 13.98±1.37 fL for stroke, 12.82±0.12 fL for MI, 12.07±0.98 fL for AKI, 11.56±0.94 fL for CKI, 12.48±1.43 fL for gangrene toe, 13.02±1.29 fL for diabetic retinopathy, and 10.36±0.72 fL for peripheral vasculopathy (Table/Fig 5).

The DM is a significant global health concern, characterised by increased prothrombotic activity, which leads to accelerated atherosclerosis, inflammation, and enhanced platelet activity (9),(10). This contributes to multi-organ involvement-including the heart, nerves, eyes, Central Nervous System (CNS), kidneys, gastrointestinal tract, and blood vessels-resulting in long-term complications associated with increased mortality and morbidity (11),(12).

Discussion

In DM, platelets are often immature, larger, and exhibit increased activity. Hyperglycaemia directly enhances platelet reactivity and promotes the glycation of platelet proteins. Both insulin resistance and insulin deficiency can increase platelet reactivity, as insulin normally inhibits platelet activation. Thus, a relative or absolute deficiency of insulin could lead to heightened platelet reactivity. Diabetic patients exhibit platelet hyperaggregability and activation, causing circulating platelets to release more granules, which shortens platelet lifespan and leads to the release of larger platelets from the bone marrow due to megakaryocyte activation. These larger and younger platelets have greater volume and are functionally more active because of increased surface markers. The resulting enhanced platelet aggregation and activation play a role in the development of various microvascular and macrovascular complications (13).

Age Distribution

In the present study, the mean age of the study population was 57.49±14.48 years. DM with complications was more prevalent in older age groups. A total of 17 (28.33%) out of 60 patients belonged to the age group of 51-60 years, 14 (23.33%) out of 60 were in the 61-70 years age group, and 12 (20%) out of 60 were over 70 years of age. In studies by Dwivedi T and Davangeri R, Spandana T et al., Shilpi K and Potekar RM, Bhattacharjee P et al., and Subashini S et al., the mean age of patients with DM and complications was similar to the present, as shown in (Table/Fig 6) (14),(15),(16),(17),(18),(19),(20).

Platelet Indices

In the present study, the mean MPV and PDW for DM without complications were 8.65±1.58 and 13.94±2.66, respectively. The mean MPV and PDW for DM with complications were 12.74±3.076 and 15.54±3.31. These findings align with the studies by Shilpi K and Potekar RM, Bhattacharjee P et al., Hekimsoy Z et al., and Jindal S et al., as shown in [Table/Fig-7,8] (13),(14),(16),(17),(18),(20),(21),(22),(23),(24). Analysis revealed that diabetic patients had higher PDW values than MPV, as PDW is independent of platelet count, while MPV is dependent on it and is calculated using a histogram.

Platelet Count

In our study, the mean platelet count for DM with complications was 3.12±1.07 lac/mm3, which is consistent with studies by Dwivedi T and Davangeri R, Subashini S et al., Taderegew M et al., and Jindal S et al., which reported mean platelet values of 257±75,600 lac/mm3, 285.29±75,380 lac/mm3, 257.9±48,500 lac/mm3, and 229.33±70,000 lac/mm3, respectively (14),(18),(20),(24).

Gylcosylated Haemoglobin (HbA1c)

In the present study, the mean HbA1c in patients with DM and complications was 8.33±1.45. The mean HbA1c in patients with DM without complications was 6.75±0.61, which is similar to the findings of studies by Dwivedi T and Davangeri R, Spandana T et al., Shilpi K and Potekar RM, (2017), and Walinjkar RS et al., which reported HbA1c levels of 8.9±1.37, 7.28±0.88, 7.3±1.1, and 7.45±1.48, respectively (14),(15),(16),(25). Patients with an HbA1c level >6.5% had higher platelet indices (MPV and PDW) than patients with an HbA1c level <6.5%.

Fasting Blood Sugar (FBS)

The mean FBS was 219.65±101.32 mg/dL for patients with DM complications and 109.96±26.17 mg/dL for those without complications, which is consistent with the study by Dwivedi T and Davangeri R which reported a mean FBS of 170±83.46 mg/dL for those with complications. Shilpi K and Potekar RM, (2017) reported a mean FBS of 158.1±33.7 mg/dL, while Taderegew M et al., (2021) and Walinjkar RS et al., reported mean FBS levels of 147.9±35.2 mg/dL and 140.48±28.05 mg/dL, respectively (14),(16),(20),(25). Both FBS and HbA1c levels were higher in patients with DM complications than in those without complications.

Platelet Count in DM with Complications

The mean platelet count was 4.09±1.15 lac/mm3 in cases of AKI and 2.77 lac/mm3±69.42/mm3 in CKI. These values are similar to the mean platelet count of 2.98 lac/mm3±68.37/mm3 reported by Subashini S et al., and 2.63 lac/mm3±45.8/mm3 by Taderegew M et al., (18),(20). The mean platelet count was 3.52±1.07 lac/mm3 in diabetic retinopathy, which is comparable to the values reported by Subashini S et al., (2.84 lac/mm3±68.37/mm3) and Taderegew M et al., (2.55 lac/mm3±55.1/mm3) (18),(20).

Platelet Indices in DM with Complications

In the present study, the mean PDW was 12.05±1.27 in cases of myocardial infarction, which was similar to the studies by Dwivedi T, Davangeri R, and Buch A et al., which reported mean PDW values of 18.7±3.43 and 14.96±3.54, respectively (14),(26). The mean PDW was 13.78±1.38 in acute kidney injury and 14.05±2.29 in chronic kidney disease, aligning with the findings by Subashini S et al., Taderegew M et al., and Buch A et al., who reported mean PDW values of 15.72±3.97, 16.6±2.8, and 15.72±3.97, respectively (18),(20),(26).

The mean PDW in peripheral vasculopathy was 11.86±1.067, which is comparable to the study by Buch A et al., which reported a mean PDW of 12.67±4.93 (26). The mean PDW in diabetic retinopathy was 14.1±3.31, similar to the studies by Subashini S et al., Taderegew M et al., and Buch A et al., which reported mean PDW values of 12.97±0.97, 16.7±2.8, and 14.92±4.14, respectively (18),(20),(26). The mean PDW in gangrenous toe was 14.8±3.15, which was similar to the result reported by Buch A et al., with a mean PDW of 15.82±4.51 (26).

The MPV in myocardial infarction was 12.82±0.12, which was similar to the study by Buch A et al., which had a mean MPV of 10.94±1.73 (26). The MPV in acute kidney injury and chronic kidney disease was 12.07±0.98 and 11.56±0.94, respectively, aligning with the findings by Subashini S et al., Taderegew M et al., and Buch A et al., who reported MPVs of 12.92±0.97, 13.8±2.5, and 11.0±2.23, respectively (18),(20),(26). The MPV in diabetic retinopathy was 13.02±1.29, which is similar to the values reported by Subashini S et al., Taderegew M et al., and Buch A et al., with MPVs of 12.9±0.97, 13.7±1.9, and 11.40±1.96, respectively (18),(20),(26). The MPV for gangrene toe and peripheral vasculopathy was 12.48±1.43 and 10.36±0.72, which was similar to the results by Buch A et al., who reported MPVs of 12.22±1.98 in diabetic foot and 10.97±1.77 in peripheral vascular disease (26).

Therefore, platelet indices play a significant role in the early detection of microvascular and macrovascular complications in diabetes mellitus, potentially preventing associated complications.

Limitation(s)

The limitation of the present study was the lack of follow-up with a few cases, which made it impossible to compare them with current findings. Nevertheless, these cases constitute only a minimal number in this study. Additionally, patients with qualitative disorders and reactive causes for elevated platelet counts were not assessed; however, these are considered to play a minor role.

Conclusion

Diabetes contributes to endothelial dysfunction and platelet hyperactivity, leading to microvascular and macrovascular complications. In patients with DM, platelets tend to be larger, more active, and have a higher thrombogenic potential, resulting in elevated platelet indices. The present study observed variations in the levels of platelet count and platelet indices between diabetic patients with and without complications. Diabetic patients with uncontrolled glycaemic indices and high fasting blood sugar levels had increased platelet indices, which led to complications in comparison to patients without complications, where the platelet count, platelet indices, and glycaemic indices were within normal limits.
