A major goal of this initiative is to facilitate the development of novel collaborative research programs among physiologists, neuroscientists, behavioral neuroscientists, imaging specialists and clinicians in order to develop integrative research programs to accelerate progress in CRPS/RSD research. This PA is intended to encourage cross-disciplinary research focused on a mechanism-based diagnostic classification of CRPS/RSD, which might lead to mechanism-based therapeutic strategy for this chronic condition. RESEARCH OBJECTIVES Background Complex Regional Pain Syndrome (CRPS), formerly known as Reflex Sympathetic Dystrophy (RSD), is a chronic debilitating condition characterized by severe burning pain, pathological changes in bone and skin, excessive sweating, tissue swelling, and extreme sensitivity to touch. It is estimated that between 2-5% of individuals with peripheral nerve injury, and up to 20% of those with paralysis on one side of the body, will suffer from RSD. Though highly debated, the syndrome is thought to evolve through three stages (acute, dystrophic, atrophic), each marked by progressive pain and physical changes in the skin, muscles, joints and bones. CRPS/RSD can affect both genders and all ages (including children), although it is thought to be more common between the ages of 40 and 60 and may be more frequent in women. The cause of CRPS/RSD is unknown, and most treatments for the symptoms experienced by CRPS/RSD patients are not optimal. Current theories of the potential mechanisms of CRPS/RSD are based on the notion that a pathologic sympathetically maintained reflex arc is involved in the generation and maintenance of pain. Although there have been many anecdotal reports of pain relief after local anesthetic or pharmacological sympathetic ganglion blockade, the sympathetic nervous system is not involved in every case. Moreover, a reflex arc has not been demonstrated in CRPS/RSD. CRPS/RSD has been subdivided into type 1 and type 2. The clinical features are similar for both subtypes and the distinguishing feature is the presence of a major peripheral nerve injury in patients with type 2. The incidence of CRPS/RSD type 1 is high in patients with stroke, spinal cord injury, multiple sclerosis and many other neurological disorders. The occurrence of CRPS/RSD is related to the intensity of the motor deficit, the spasticity and the sensory deficits in these patients. Despite recognition of the comorbidity of CRPS/RSD with other neurological disorders and the disabling consequences of the condition, a clear understanding of the disorder is still lacking. This paucity of information often results in inappropriate treatment modalities and delay in treatment affecting long term recovery of CRPS/RSD patients. Scope CRPS/RSD is thought to be a form of central hypersensitization in which the central nervous system overreacts to the incoming noxious stimuli. Several plausible theories have been advanced to explain the CRPS/RSD disorder, including the formation of dysfunctional synapses after peripheral nerve injury, sensitization of peripheral sensory receptors, abnormal discharges in sympathetic and nociceptive afferent nerves after trauma, improper communication with the central nervous system through damaged and necrotic nerve endings, spontaneous electrical discharges, and increased responsiveness to high-threshold and slow conducting C-fibers. The disorder could result from peripheral afferent mechanisms, peripheral efferent mechanisms, central mechanisms (including psychological mechanisms), or combinations of more than one mechanism. While theories abound, there has been a paucity of research to elucidate the pathophysiology of CRPS/RSD. CRPS/RSD is characterized in the acute stage by symptoms of regional inflammation. This inflammatory response is also seen in the rodent chronic nerve constriction injury model that is produced by loose ligation of the sciatic nerve. Inflammation could be caused by cellular hypoxia and diminished oxygen utilization. In the chronic stage, CRPS/RSD is manifested as a more neuropathy-like disorder. It has been hypothesized that this alteration results from the development of sensitization or plasticity during the early inflammation phase of the disorder. Impairments of sympathetic vasoconstrictor activity and other autonomic functions have been observed in CRPS patients. Pain is maintained by sympathetic efferent innervation or by supersensitivity to circulating catecholamines and can be relieved by a sympatholytic procedure such as ganglionic nerve blockade or pharmacological intervention. It is not yet known how direct and indirect effects in the manifestation of pain are achieved. Clinical examination and quantitative assessment of neurologic function in CRPS/RSD reveal abnormalities of spinothalamic, trigemino-thalamic, and corticospinal function, suggesting medullary dysfunction in RSD/CPRS. Moreover, recent imaging studies have suggested that prefrontal abnormalities may alter pain consciousness in CRPS/RSD patients. The development and maintenance of the disorder may be influenced by psychological factors such as anxiety, depression and life stressors. The clinical manifestations of CRPS/RSD are widespread throughout the body with inflammation associated with increased temperature, edema, redness, pain and loss of function. The mediators of one or more of these manifestations including various neuropeptides, cytokines, eicosanoids, substance P, and steroids offer various classes of pharmaceutical compounds as potential therapeutic agents for development and clinical testing in this disease. Future research on the mechanisms of CRPS/RSD must be much better integrated with clinical observations in human patients. Design of both animal and human models must be more closely integrated with each other and with the clinic in order to focus the scientific questions, the formulation of hypotheses and the experimental approaches. Interdisciplinary and multidisciplinary approaches could help uncover the pathophysiology of CRPS/RSD and improve treatment of this disorder. The present PA seeks to achieve this overall goal by creating basic research programs in association with the clinic in which the CRPS/RSD patients are diagnosed and treated. These research programs would require the involvement of experts from a wide variety of clinical and basic research areas, including neuroimaging, pain, neural plasticity, the sympathetic nervous system and the immune system. Examples of potential research questions would include but not be limited to issues such as: o Development and validation of animal models that recapitulate the unique features of CRPS/RSD o Characterization of neurobiological mechanisms of CRPS/RSD including peripheral afferent and efferent mechanisms, central mechanisms and factors that influence these processes o Studies of neurotransmitter systems and neuropeptides involved in CRPS/RSD o Studies of signaling mechanisms in CRPS/RSD o Research on the immune system mechanisms and autoimmune inflammatory processes in CRPS/RSD (for example, role of glial cell activation and cytokine release in central and peripheral pathophysiology of CRPS/RSD) o Studies of the role of estrogen (genomic and non-genomic effects) in the pathophysiology of CRPS/RSD o Studies that investigate the correlation between the clinical manifestations of CRPS and the underlying neurobiological and neurochemical mechanisms that will provide the means to measure the effect of therapeutic interventions on specific targets in clinical trials o Translational studies that integrate the research paradigms validated in animal and human models with clinical research on patients (development and application of clinically relevant assays of nociception in human studies) o Studies of gene and protein expression profiling in models of CRPS/RSD o Development of new CRPS/RSD therapies for prospective clinical trials o Neuroimaging studies of nervous system activation in CRPS/RSD o Comparison of brain activation studies between normal pain as compared to pain experienced by RSD/CRPS patients (allodynia, hyperalgesia) in order to identify which regions of the nervous system are abnormally activated in this disease state o Studies of the effect of psychological stress on CRPS/RSD in the context of disease progression and treatment response o Development of standardized diagnostic criteria for CRPS/RSD o Assessment of risk factors and incidence of CRPS/RSD through epidemiological studies o Studies of disease mechanisms that give rise to CRPS/RSD in susceptible individuals o Studies that assess the effect of gender, age and co-morbid neurological conditions on the development and maintenance of CRPS/RSD Summary Though this solicitation, the NINDS encourages a broad analysis of the experience of pain and recommend that an integrated approach be adopted toward the development of new treatment modalities. Research programs that combine anatomical, physiological, psychological, or molecular approaches are needed to accelerate progress in Complex Regional Pain Syndrome (CPRS)/Reflex Sympathetic Dystrophy (RSD) research. This PA initiative will encourage applications to study CRPS/RSD in the context of 1) disease mechanisms, 2) CRPS/RSD model systems, 3) epidemiology, 4) diagnostic criteria, 5) integration between basic research and clinical research, and 6) therapy.

The CSR will not accept any application in response to this PA that is essentially the same as one currently pending initial review unless the applicant withdraws the pending application. The CSR will not accept any application that is essentially the same as one already reviewed. This does not preclude the submission of a substantial revision of an application already reviewed, but such application must include an Introduction addressing the previous critique. Although there is no immediate acknowledgement of the receipt of an application, applicants are generally notified of the review and funding assignment within 8 weeks. PEER REVIEW PROCESS Applications submitted for this PA will be assigned on the basis of established PHS referral guidelines. An appropriate scientific review group convened in accordance with the standard NIH peer review procedures (http://www.csr.nih.gov/refrev.htm) will evaluate applications for scientific and technical merit. As part of the initial merit review, all applications will: o Receive a written critique o Undergo a selection process in which only those applications deemed to have the highest scientific merit, generally the top half of applications under review, will be discussed and assigned a priority score o Receive a second level review by the appropriate national advisory council or board REVIEW CRITERIA The goals of NIH-supported research are to advance our understanding of biological systems, improve the control of disease, and enhance health. In the written comments, reviewers will be asked to discuss the following aspects of your application in order to judge the likelihood that the proposed research will have a substantial impact on the pursuit of these goals: o Significance o Approach o Innovation o Investigator o Environment The scientific review group will address and consider each of these criteria in assigning your application's overall score, weighting them as appropriate for each application. Your application does not need to be strong in all categories to be judged likely to have major scientific impact and thus deserve a high priority score. For example, you may propose to carry out important work that by its nature is not innovative but is essential to move a field forward. (1) SIGNIFICANCE: Does your study address an important problem? If the aims of your application are achieved, how do they advance scientific knowledge? What will be the effect of these studies on the concepts or methods that drive this field? (2) APPROACH: Are the conceptual framework, design, methods, and analyses adequately developed, well integrated, and appropriate to the aims of the project? Do you acknowledge potential problem areas and consider alternative tactics? (3) INNOVATION: Does your project employ novel concepts, approaches or methods? Are the aims original and innovative? Does your project challenge existing paradigms or develop new methodologies or technologies? (4) INVESTIGATOR: Are you appropriately trained and well suited to carry out this work? Is the work proposed appropriate to your experience level as the principal investigator and to that of other researchers (if any)? (5) ENVIRONMENT: Does the scientific environment in which your work will be done contribute to the probability of success? Do the proposed experiments take advantage of unique features of the scientific environment or employ useful collaborative arrangements? Is there evidence of institutional support? ADDITIONAL REVIEW CRITERIA: In addition to the above criteria, the following items will be considered in the determination of scientific merit and the priority score: PROTECTIONS: The adequacy of the proposed protection for humans, animals, or the environment, to the extent they may be adversely affected by the project proposed in the application. INCLUSION: The adequacy of plans to include subjects from both genders, all racial and ethnic groups (and subgroups), and children as appropriate for the scientific goals of the research. Plans for the recruitment and retention of subjects will also be evaluated. (See Inclusion Criteria included in the section on Federal Citations, below) BUDGET: The reasonableness of the proposed budget and the requested period of support in relation to the proposed research. AWARD CRITERIA Applications submitted in response to a PA will compete for available funds with all other recommended applications. The following will be considered in making funding decisions: o Scientific merit of the proposed project as determined by peer review o Availability of funds o Relevance to program priorities REQUIRED FEDERAL CITATIONS HUMAN SUBJECTS PROTECTION: Federal regulations (45CFR46) require that applications and proposals involving human subjects must be evaluated with reference to the risks to the subjects, the adequacy of protection against these risks, the potential benefits of the research to the subjects and others, and the importance of the knowledge gained or to be gained. http://www.hhs.gov/ohrp/humansubjects/guidance/45cfr46.htm INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH: It is the policy of the NIH that women and members of minority groups and their sub-populations must be included in all NIH-supported clinical research projects unless a clear and compelling justification is provided indicating that inclusion is inappropriate with respect to the health of the subjects or the purpose of the research. This policy results from the NIH Revitalization Act of 1993 (Section 492B of Public Law 103-43). All investigators proposing clinical research should read the "NIH Guidelines for Inclusion of Women and Minorities as Subjects in Clinical Research - Amended, October, 2001," published in the NIH Guide for Grants and Contracts on October 9, 2001 (http://grants.nih.gov/grants/guide/notice-files/NOT-OD- 02-001.html); a complete copy of the updated Guidelines are available at http://grants.nih.gov/grants/funding/women_min/guidelines_amended_10_2001 .htm. The amended policy incorporates: the use of an NIH definition of clinical research; updated racial and ethnic categories in compliance with the new OMB standards; clarification of language governing NIH-defined Phase III clinical trials consistent with the new PHS Form 398; and updated roles and responsibilities of NIH staff and the extramural community. The policy continues to require for all NIH-defined Phase III clinical trials that: a) all applications or proposals and/or protocols must provide a description of plans to conduct analyses, as appropriate, to address differences by sex/gender and/or racial/ethnic groups, including subgroups if applicable; and b) investigators must report annual accrual and progress in conducting analyses, as appropriate, by sex/gender and/or racial/ethnic group differences. INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN SUBJECTS: The NIH maintains a policy that children (i.e., individuals under the age of 21) must be included in all human subjects research, conducted or supported by the NIH, unless there are scientific and ethical reasons not to include them. This policy applies to all initial (Type 1) applications submitted for receipt dates after October 1, 1998. All investigators proposing research involving human subjects should read the "NIH Policy and Guidelines" on the inclusion of children as participants in research involving human subjects that is available at http://grants.nih.gov/grants/funding/children/children.htm REQUIRED EDUCATION ON THE PROTECTION OF HUMAN SUBJECT PARTICIPANTS: NIH policy requires education on the protection of human subject participants for all investigators submitting NIH proposals for research involving human subjects. You will find this policy announcement in the NIH Guide for Grants and Contracts Announcement, dated June 5, 2000, at http://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-039.html. PUBLIC ACCESS TO RESEARCH DATA THROUGH THE FREEDOM OF INFORMATION ACT: The Office of Management and Budget (OMB) Circular A-110 has been revised to provide public access to research data through the Freedom of Information Act (FOIA) under some circumstances. Data that are (1) first produced in a project that is supported in whole or in part with Federal funds and (2) cited publicly and officially by a Federal agency in support of an action that has the force and effect of law (i.e., a regulation) may be accessed through FOIA. It is important for applicants to understand the basic scope of this amendment. NIH has provided guidance at http://grants.nih.gov/grants/policy/a110/a110_guidance_dec1999.htm. Applicants may wish to place data collected under this PA in a public archive, which can provide protections for the data and manage the distribution for an indefinite period of time. If so, the application should include a description of the archiving plan in the study design and include information about this in the budget justification section of the application. In addition, applicants should think about how to structure informed consent statements and other human subjects procedures given the potential for wider use of data collected under this award. STANDARDS FOR PRIVACY OF INDIVIDUALLY IDENTIFIABLE HEALTH INFORMATION: The Department of Health and Human Services (DHHS) issued final modification to the "Standards for Privacy of Individually Identifiable Health Information", the "Privacy Rule," on August 14, 2002. The Privacy Rule is a federal regulation under the Health Insurance Portability and Accountability Act (HIPAA) of 1996 that governs the protection of individually identifiable health information, and is administered and enforced by the DHHS Office for Civil Rights (OCR). Those who must comply with the Privacy Rule (classified under the Rule as "covered entities") must do so by April 14, 2003 (with the exception of small health plans which have an extra year to comply). Decisions about applicability and implementation of the Privacy Rule reside with the researcher and his/her institution. The OCR website (http://www.hhs.gov/ocr/) provides information on the Privacy Rule, including a complete Regulation Text and a set of decision tools on "Am I a covered entity?" Information on the impact of the HIPAA Privacy Rule on NIH processes involving the review, funding, and progress monitoring of grants, cooperative agreements, and research contracts can be found at http://grants.nih.gov/grants/guide/notice-files/NOT-OD-03-025.html. URLs IN NIH GRANT APPLICATIONS OR APPENDICES: All applications and proposals for NIH funding must be self-contained within specified page limitations. Unless otherwise specified in an NIH solicitation, Internet addresses (URLs) should not be used to provide information necessary to the review because reviewers are under no obligation to view the Internet sites. Furthermore, we caution reviewers that their anonymity may be compromised when they directly access an Internet site. HEALTHY PEOPLE 2010: The Public Health Service (PHS) is committed to achieving the health promotion and disease prevention objectives of "Healthy People 2010," a PHS-led national activity for setting priority areas. This RFA is related to one or more of the priority areas. Potential applicants may obtain a copy of "Healthy People 2010" at http://www.health.gov/healthypeople. AUTHORITY AND REGULATIONS: This program is described in the Catalog of Federal Domestic Assistance at http://www.cfda.gov/ and is not subject to the intergovernmental review requirements of Executive Order 12372 or Health Systems Agency review. Awards are made under the authorization of Sections 301 and 405 of the Public Health Service Act as amended (42 USC 241 and 284) and under Federal Regulations 42 CFR 52 and 45 CFR Parts 74 and 92. All awards are subject to the terms and conditions, cost principles, and other considerations described in the NIH Grants Policy Statement. The NIH Grants Policy Statement can be found at http://grants.nih.gov/grants/policy/policy.htm. The PHS strongly encourages all grant recipients to provide a smoke-free workplace and discourage the use of all tobacco products. In addition, Public Law 103-227, the Pro-Children Act of 1994, prohibits smoking in certain facilities (or in some cases, any portion of a facility) in which regular or routine education, library, day care, health care, or early childhood development services are provided to children. This is consistent with the PHS mission to protect and advance the physical and mental health of the American people.
