"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."

Dr. Mamta Gupta,
"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: Hepatitis C infections continue to be a threat to safe transfusion practices. We analyzed the prevalence and trends of the Hepatitis C infection among voluntary and replacement donors in a 6.5 years retrospective study from January 2005 till June 2011 at the blood bank at Sri Guru Ram Das Institute of Medical Sciences And Research, Vallah, Amritsar, India. The donors were evaluated for the sero prevalence of the Hepatitis- C virus (HCV).

Methods: A total of 35793 healthy blood donations which were collected from January 2005 to July 2011 were screened for anti -HCV antibodies by using third and fourth generation (for confirmation) ELISA kits (HCV Microlisa; J. Mitra/ Eliscan HCV; RFCL Qualisa HCV; Qualpro) with a reported sensitivity and a specificity of 100% each (for the fourth generation kits).

Results: Out of these, 7089(19.8%) were voluntary donors and 28704 (80.1%) were replacement donors. 493 blood donors tested positive for HCV. The average prevalence in percentage was found to be 1.38%. The prevalence rate showed a decline from 2.03% in 2005 to 0.87% by June 2011. The statistical analysis which was done by using the Chi-square test (51.193), demonstrated that the decreasing trend in the prevalence of HCV was statistically significant.

Conclusion: The screening of blood products is the only way to prevent the transfusion associated complications and this should be rigorously implemented. There is a need to stress more stringent donor selection criteria to ensure a safer blood supply. The health authorities need to include hepatitis C on their radar as a disease which can result in significant morbidity and mortality in the years to come.

Introduction
The use of blood transfusion in clinical practice has brought untold benefits to countless individuals, but simultaneously, unsafe transfusion practices carry the risk of transmitting life- threatening Transfusion – Transmissible Infections (1). The strategies which were used to reduce Transfusion Transmitted Infections (TTI) have been extremely effective. Some of the strategies include improving the donor selection, testing the donated blood for antibodies for infectious agents, reducing the exposure to allogenic blood by the use of autologous transfusions and changing the transfusion guidelines to use blood more conservatively (2). TTI is a major concern to the patients, physicians and the policy makers who wish to see a risk free blood supply. Hepatitis C is the major cause of acute hepatitis after a blood transfusion, that is neither related to Hepatitis A nor to Hepatitis B. It was first detected in 1989 by the extensive testing of serum from experimentally infected animals by using molecular biology techniques (3). Later, it was characterized to be a small, enveloped, RNA virus which belonged to the flavin family. An important feature of the HCV genome is its high degree of genetic variability and the different mutants of the parent strains which co exist as quasi species in a single infected individual. The genomic instability and the antigenic variability have seriously hamperedSectionthe efforts which were made for developing an HCV vaccine. It has been estimated that 3% of the world’s population or that almost 200 million individuals have chronic HCV infection (4). Several studies on voluntary and mixed blood donors have noted a prevalence of hepatitis of below 2% in India (5),(6).

Punjab has been found to have the maximum number of HCV carriers due to the use of unsterilized syringes and recycled needles by drug abusers and lack of awareness about the prevention and the treatment of this disease (7). More recently, blood transfusion has emerged as one of the most common transmission pathways of HCV, which is the major cause of acute hepatitis after a blood transfusion, that is neither related to Hepatitis A nor to Hepatitis B. Serosurveys one of the primary methods to determine the prevalence of the HCV seorpositivity. The assessment of the infection thereby helps in determining the safety of the blood products. The present study was a six and a half year retrospective study. It presented the data on the seroprevalence of the Hepatitis C virus among the voluntary and the replacement donors in the Amritsar district of Punjab, in a teaching tertiary care hospital. This study gave an overview of the epidemiology/prevalence of Hepatitis C in this part of the country. The aim of this study was to lay stress on enhancing the standards of the blood banking system and tomake long term strategies to decrease the transmission of this deadly virus.

Material and Methods

This study was conducted in the blood bank, a unit of the Department of Pathology, Sri Guru Ram Das Institute of Medical Sciences and Research, Vallah, Amritsar, Punjab, India. A total of 35,793 healthy blood donors (both voluntary and replacement) were reviewed for Hepatitis C among other mandatory tests, over a period of 6.5 years, from the records of the blood bank of the institute. The blood donations which were collected from January 2005 to July 2011 were screened for the presence of anti HCV antibodies by using third and fourth generation (for confirmation) ELISA kits (HCV Microlisa; J. Mitra/ Eliscan HCV; RFCL Qualisa HCV; Qualpro) with a reported sensitivity and a specificity of 100% each (for the fourth generation kits). The third generation anti-HCV ELISA tests kits utilize a combination of antigens with the sequences of both the HCV structural and non structural antigens i.e. Core, E1, E2, NS3, NS4 and NS5, with increased sensitivity and specificity .The ELISA was validated by the acceptance criteria which were laid down by the manufacturer for the absorbance of the reagent blank as well as for the mean absorbance of the positive and negative controls which were provided with the test kits. The cut off value was calculated as per manufacturer’s directions for reporting the positive and the negative results. Known positive and negative samples were used randomly as the external controls in each screening.

The donors were selected and screened thoroughly, as per the guidelines of the Gazette of India (8). Professional blood donors and those with a previous history of jaundice were excluded. All the blood donors were pre-counseled and they were asked to fill a form as a part of the routine blood donation screening procedure. In this form, the donors gave their consent and they authorized the blood bank to test their blood as per the law and to use it as it was deemed fit. The information regarding the risk factors like a history of surgery, hospitalization, blood transfusion, occupation, high risk behaviour and tattoo marks was specifically taken. All the reactive samples were repeat tested before they were labelled as seropositive. The data retrieved was tabulated annually. The statistical analysis was done. Chi-squared (x2) statistics was used to estimate whether a significant difference existed between the prevalence of Hepatitis- C over the years or not.

Results

A total of 35793 units of blood were collected over a period of 6.5 years. Among these, 19.8% were from voluntary donors and 80.2% were from replacement donors (Table/Fig 1).The voluntary donations increased in number year over year, though the replacement donors still continued to comprise the major chunk of the donations. Even the number of donations gradually increased during the past 6 years from 4720 in 2005 to 6743 in 2010. The %age of the HCV seropositivity showed a gradual downward trend from 2.03% in 2005 to 0.87% in July 2011, with an overall seropositivity of 1.38%. Chi-squared test = 51.193; Degree of Freedom (df) =6; p-value= <0.001, which was significant. The year wise change in the Hepatitis C prevalence had declined over the years and it was statistically significant.(Table/Fig 2).

Discussion

In the present retrospective study, we evaluated the seroprevalence of the Hepatitis C virus among the blood donors in and around the Amritsar district. This study gave an overview of the epidemiology of the disease in the community. The figures from the epidemiology studies in different regions of India were compared (Table/Fig 2). The data will help in evaluating the seroprevalence of the Hepatitis C infection in India. The Hepatitis C infection is spreading fast in India. Over one lakh people get infected by the deadly HCV virus every year. According to the Indian National Association for the Study of the Liver, nearly 12.5 million Indians are suffering from the Hepatitis C disease, with the death rate exceeding over one lakh. Hepatitis C has increasingly been found to be a significant aetiological agentwhich causes liver disease in India. The clinical manifestations include acute hepatitis, chronic hepatitis, cirrhosis and hepatocellular carcinoma (9). The Hepatitis C infection is one of the transfusion transmissible infections and hence, it is mandatory to test all the blood donors for its presence. To ensure the transfusion of safe blood to the recipient, not only a mandatory screening of such infection markers is necessary, but it is also important to study the prevalence and the risk factors of the HCV infection among the donor population.

In the present study, the number of HCV positive cases dropped from 96 in 2005 to 66 in 2010. The anti-HCV seropositivity also came down from 2.06% to 0.96% in 2010 and till mid 2011, it was found to be 1.008%. The average seroprevalence of HCV over a period of 6.5 years was found to be 1.38%. A similar study in Chandigarh observed an overall seropositivity of 0.44% (72/16,250) among the blood donors. There was no prior history of blood transfusion in any of these donors; however, a history of some surgical procedures was present in 25.8% of the donors. Another study in Rajasthan evaluated the seroprevalence of the blood donors to be 0.29%. However, the data in this study was collected in 5 years from 3870 donors (10). Studies from eastern India, one from Sikkim, detected the seroprevalence of HCV to be 0.27% among 3735 blood donors (11). The other from West Bengal detected an increased prevalence of HCV from 314 in 2004 to 372 in 2005. The percentage increase was from 0.28% in 2004 to 0.35% in 2005, which was statistically significant (12).

A similar study which was carried out among the Armed Forces showed that the seropositivity for anti-HCV had decreased amongst the voluntary donors from 0.46% to 0.20% and that in the replacement donors, it had increased from 0.43% to 0.65% in a span of 4 years from 2000 till 2004 (13). The study emphasized the implementation of strict donor criteria and the use of sensitive laboratory screening tests to reduce the incidence of TTI in Indian scenarios. A study from Andhra Pradesh showed a higher seroprevalence of HCV in the blood donors. The study estimated the prevalence to be 0.84% from a total of 8067 donors over a six year period from 2004 to 2009. In this study, the prevalence of HCV among the donors showed a downward trend over a period of six years (14). Our present study showed similar results, in which the prevalence of HCV among the donors also showed a decreasing trend over a period of more than 6 years from 2.03% in 2005 to 1.008% by mid 2011. A study from northern India, from east Delhi, showed that the prevalence of the antibodies for HCV ranged from 0.65% (15). The anti HCV positivity was found to vary from 0.91% to 1.09% (483/44064) in two other studies (16),(17).

The prevalence of the seropositivity for anti-HCV in a 4 year study which was done by Pahuja et al., was found to 0.66%. The study showed a decline of the seroprevalence of HCV from 1.01% in the year 2002 to 0.29% in 2005 (18). The seroprevalence in the present study has also reduced over the years. The number of new infections have dropped, probably due to the identification of the virus and due to the increased awareness of the blood borne pathogens. This has reduced the spread of the virus through transfusion, injection drug use, unprotected sexual activity and workplace exposure incidents.

A variation in the seropositivity was also seen due to the difference in the donor base, the testing methodology and its stringent regulations, the degree to which the risk factors are prevalent in the donor population, the literacy rate and the self exclusion by the high risk donors. There are studies which raise serious concerns regarding the Hepatitis-B virus (HBV) and the HCV prevalence in our country. Although the HBV transmission is showing a decreasing trend, it cannot be relied upon, because the donors were screened only for the HBsAg. In fact, the inclusion of the antibody to the Hepatitis B core antigen and other sensitive markers to the screening protocol, and better donor recruitment is the need of the hour. HCV is clearly on the rise. An increasing trend in the seroprevalence of Hepatitis C shows that it may replace Hepatitis B as the most common cause of liver failure (19).

Currently, the blood donations are screened only for anti-HCV. The screening for the HCV RNA is at present, not practical, and probably not appropriate in most of the cases. A major problem that was being faced by the transfusion services and the laboratories at the start of the anti-HCV screening was the generally poor specificity of the anti-HCV screening assays. A second problem was that true confirmatory assays were not yet available. The prevalence of HCV, as was apparent from this study, has gradually declined. But still, the seropositivity of HCV in the blood donors of Amritsar is high as compared to that which was found in the studies from other parts of India. The data in (Table/Fig 2) presents the picture of the prevalence of the Hepatitis C infection in various regions of India.

The reasons for the increasing trend in most of the studies are widespread drug abuse and lack of awareness about the prevention and treatment of Hepatitis C, especially in rural areas. Besides the difficulty in developing a vaccine against HCV, there is an added handicap that the elevated titres of anti-HCV IgG which occur after the infection do not confer active immunity. Moreover, HCV is able to actively evade the Interferon mediated cellular antiviral response. And to add to the problem, the window period for HCV has a long range (6-12 weeks), during which anti HCV cannot be detected in the blood, thus making the blood donation very dangerous and life threatening for the recipient. The clinical significance of the presence of the anti-HCV antibodies in healthy blood donors remains uncertain. The anti-HCV positive blood donors are usually asymptomatic and they have no symptoms that obviously relate to liver disease and deny any risk factors from the exposure to viral hepatitis during the pre-donation questioning. Various western studies have suggested that 60-80 per cent of the blood donors with anti-HCV have elevated serum aminotransferase levels (20),(21). The elevations in most of the cases are persistent, indicating the presence of chronic hepatitis. Furthermore, most of the anti-HCV positive blood donors have HCV RNA in the serum and they can transmit Hepatitis C, regardless of whether the serum aminotransferases are elevated or not (22). The HCV positive donors should be informed about their disease, counseled and referred to a hepatologist. They should also be permanently deferred for future donations (5).

Conclusion

The given data raises serious concerns regarding the HCV prevalence in Punjab. Although HCV showed decreasing trends, thereis an immediate need of developing locally relevant guidelines for the counseling and the further management of the HCV seropositive donors. Prevention is the only effective cure which is available at present for the HCV infection and so in such scenarios, propaganda and education of the masses regarding the prevention and the consequences of acquiring the HCV infection becomes extremely important. This increasing trend should be considered seriously and alarming bells should be raised by the health authorities. The screening and the treatment of blood products is the only way for preventing the transfusion associated cases and these should be rigorously implemented. The introduction of donor counseling, screening for different pathogens and donor self exclusion and ensuring a 100% voluntary blood donation will be effective in decreasing the hepatitis rate. The results of these studies will help in improving the standards of the blood banking systems in India and long term strategies can be made to improve the public health and to decrease the transmission of this deadly virus.
