Abstract
Fibromyalgia (FM) is a chronic disease characterized by widespread musculoskeletal pain of unknown etiology. The condition is commonly associated with other symptoms, including fatigue, sleep disturbances, cognitive impairment, and depression. For this reason, FM is also referred to as FM syndrome. The nature of the pain is defined as nociplastic according to the latest international classification and is characterized by altered nervous sensitization both centrally and peripherally. Psychosocial conditions have traditionally been considered critical in the genesis of FM. However, recent studies in animal models and humans have provided new evidence in favor of an inflammatory and/or autoimmune pathogenesis. In support of this hypothesis are epidemiological data of an increased female prevalence, similar to that of autoimmune diseases, and the frequent association with immune-mediated inflammatory disorders. In addition, the observation of an increased incidence of this condition during long COVID revived the hypothesis of an infectious pathogenesis. This narrative review will, therefore, discuss the evidence supporting the immune-mediated pathogenesis of FM in light of the most current data available in the literature.

Plaut S. Scoping review and interpretation of myofascial pain/fibromyalgia syndrome: An attempt to assemble a medical puzzle. PLoS One 2022; 17:e0263087. [PMID: 35171940 PMCID: PMC8849503 DOI: 10.1371/journal.pone.0263087] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 01/11/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Myofascial Pain Syndrome (MPS) is a common, overlooked, and underdiagnosed condition and has significant burden. MPS is often dismissed by clinicians while patients remain in pain for years. MPS can evolve into fibromyalgia, however, effective treatments for both are lacking due to absence of a clear mechanism. Many studies focus on central sensitization. Therefore, the purpose of this scoping review is to systematically search cross-disciplinary empirical studies of MPS, focusing on mechanical aspects, and suggest an organic mechanism explaining how it might evolve into fibromyalgia. Hopefully, it will advance our understanding of this disease. METHODS Systematically searched multiple phrases in MEDLINE, EMBASE, COCHRANE, PEDro, and medRxiv, majority with no time limit. Inclusion/exclusion based on title and abstract, then full text inspection. Additional literature added on relevant side topics. Review follows PRISMA-ScR guidelines. PROSPERO yet to adapt registration for scoping reviews. FINDINGS 799 records included. Fascia can adapt to various states by reversibly changing biomechanical and physical properties. Trigger points, tension, and pain are a hallmark of MPS. Myofibroblasts play a role in sustained myofascial tension. Tension can propagate in fascia, possibly supporting a tensegrity framework. Movement and mechanical interventions treat and prevent MPS, while living sedentarily predisposes to MPS and recurrence. CONCLUSIONS MPS can be seen as a pathological state of imbalance in a natural process; manifesting from the inherent properties of the fascia, triggered by a disrupted biomechanical interplay. MPS might evolve into fibromyalgia through deranged myofibroblasts in connective tissue ("fascial armoring"). Movement is an underemployed requisite in modern lifestyle. Lifestyle is linked to pain and suffering. The mechanism of needling is suggested to be more mechanical than currently thought. A "global percutaneous needle fasciotomy" that respects tensegrity principles may treat MPS/fibromyalgia more effectively. "Functional-somatic syndromes" can be seen as one entity (myofibroblast-generated-tensegrity-tension), sharing a common rheuma-psycho-neurological mechanism.

Abstract
Ritonavir is a BCS class II antiretroviral agent which shows poor aqueous solubility and low oral bioavailability. The cocrystallization approach was selected to overcome these problems and to improve the physicochemical and mechanical properties of Ritonavir. The novel pharmaceutical Ritonavir-L-tyrosine cocrystals (RTC at a molar ratio of 1:1) were synthesized using the liquid assisted grinding (LAG) method. The possibility of molecular interactions between drug and coformer were studied using Gold software version 5.2. The newly formed crystalline solid phase was characterized through Differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), Fourier transform-infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), and Solid-State Nuclear magnetic resonance (SSNMR). The improved pharmaceutical properties were confirmed by solubility, dissolution, and powder compaction study. The prepared cocrystals exhibited an 11.24-fold increase in solubility and a 3.73-fold increase in % of drug release at 1 h compared to pure drug. Tabletability and compaction behaviour of the pure drug and cocrystal with added excipients assessed. The tabletability profile of cocrystals showed enhanced tabletting performance as compared to pure drug. The stability studies revealed that cocrystals were stable for at least one month when stored at 40 °C/75% RH and 25 °C/60% RH conditions. The cocrystallization approach was found to be very promising and showed an overall improved performance of Ritonavir.

Abstract
BACKGROUND Fibromyalgia is a chronic pain syndrome of unknown etiology characterized by chronic widespread musculoskeletal pain and tenderness. It affects the quality of life of patients and has been associated with the human immunodeficiency virus (HIV). The study aimed to determine the prevalence of fibromyalgia in HIV-positive patients and assess the effect of fibromyalgia on their functional status. METHODOLOGY This was a cross-sectional study comprising 160 treatment-naive HIV-positive patients and 160 age- and sex-matched HIV-negative controls. The diagnosis of fibromyalgia was based on the 2011 modification of the 2010 American College of Rheumatology diagnostic criteria by assessing the widespread pain index and symptom severity score. The severity of fibromyalgia was assessed with the revised fibromyalgia impact questionnaire. RESULTS The prevalence of fibromyalgia in HIV-positive individuals was found to be 10.6%, which was significantly higher compared with controls (3.1%; P = .008). There was no significant association between fibromyalgia and age, gender, or occupation. There was a significant relationship between CD4 count levels (P < .001), WHO clinical stage (P < .001), and fibromyalgia. A statistically significant higher score on the Revised FM Impact Questionnaire was found in HIV-positive individuals with fibromyalgia (P < .001). CONCLUSION The study found that HIV-positive patients had a significantly higher incidence of fibromyalgia than controls and this was related to active indices of HIV disease. Fibromyalgia had a greater clinical impact on HIV patients than in controls. As a result, fibromyalgia should be identified and treated in people living with HIV.

Abstract
OBJECTIVE Musculoskeletal manifestations in children infected with human immunodeficiency virus (HIV) are responsible for increased morbidity and decreased quality of life. Even in this era of highly active anti-retroviral therapy (HAART), there are limited studies on different rheumatological manifestations in pediatric patients with HIV, and the spectrum of musculoskeletal manifestation in pediatric HIV is yet to be established. METHODS A single-center, prospective, observational study was carried out from October 2014 to September 2016 in a tertiary care hospital of Eastern India with 517 children infected with HIV aged between 3 and 19 years. Particulars of musculoskeletal involvement were at first screened with pediatric gait, arm, leg, spine (pGALS) screening protocol, followed by detailed examination in patients identified through screening. All the participants were re-examined at three and six months of follow-up. RESULTS Musculoskeletal manifestations were found in 11.2% of the study population. The most common non-infective manifestation found in the study population was arthralgia (5.22%), followed by myalgia (3.29%). The prevalence of definite arthritis was found to be 6/1000 children, whereas infective manifestations (including arthritis, myositis, and osteomyelitis) were found in 2.12% of study population. Musculoskeletal manifestations were commonly found in children infected with HIV who were on anti-retroviral drugs. These manifestations were found commonly in the children in the second decade of their lives. Malnutrition, advanced stage of HIV infection (WHO clinical stage 4), lower CD4 count at the time of evaluation, and longer duration of disease were associated with increased frequency of musculoskeletal manifestations. CONCLUSION Musculoskeletal manifestations are frequent in pediatric population infected with HIV. But for better delineation, further multicentric studies are warranted in future in children infected with HIV.

Abstract
Chronic pain remains a prevalent and disabling problem for people living with HIV in the current antiretroviral treatment era. Psychosocial treatments may have promise for managing the impact of this pain. However, research is needed to identify psychosocial processes to target through such treatments. The current systematic review and meta-analysis examined the evidence for psychosocial factors associated with pain, disability, and quality of life in people living with HIV and persistent pain. Observational and experimental studies reporting on the association between one or more psychosocial factors and one or more pain-related variables in an adult sample of people living with HIV and pain were eligible. Two reviewers independently conducted eligibility screening, data extraction, and quality assessment. Forty-six studies were included in the review and 37 of these provided data for meta-analyses (12,493 participants). "Some" or "moderate" evidence supported an association between pain outcomes in people with HIV and the following psychosocial factors: depression, psychological distress, posttraumatic stress, drug abuse, sleep disturbance, reduced antiretroviral adherence, health care use, missed HIV clinic visits, unemployment, and protective psychological factors. Surprisingly, few studies examined protective psychological factors or social processes, such as stigma. There were few high-quality studies. These findings can inform future research and psychosocial treatment development in this area. Greater theoretical and empirical focus is needed to examine the role of protective factors and social processes on pain outcomes in this context. The review protocol was registered with PROSPERO (CRD42016036329).

Abstract
Pain has always been an important part of human immunodeficiency virus (HIV) disease and its experience for patients. In this guideline, we review the types of chronic pain commonly seen among persons living with HIV (PLWH) and review the limited evidence base for treatment of chronic noncancer pain in this population. We also review the management of chronic pain in special populations of PLWH, including persons with substance use and mental health disorders. Finally, a general review of possible pharmacokinetic interactions is included to assist the HIV clinician in the treatment of chronic pain in this population.It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. The Infectious Diseases Society of American considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.

Abstract
BACKGROUND Irritable bowel syndrome and other gastrointestinal (GI) and non-GI disorders such as functional dyspepsia, fibromyalgia, temporomandibular joint disorder, interstitial cystitis/painful bladder syndrome, and chronic fatigue syndrome are known as functional pain syndromes. They commonly coexist within the same individual. The pathophysiologic mechanisms of these disorders are not well understood, but it has been hypothesized that they share a common pathogenesis. PURPOSE The objective of this review is to discuss the proposed pathophysiologic mechanisms, which have been similarly studied in these conditions. These mechanisms include enhanced pain perception, altered regional brain activation, infectious etiologies, dysregulations in immune and neuroendocrine function, and genetic susceptibility. Studies suggest that these functional disorders are multifactorial, but factors which increase the vulnerability of developing these conditions are shared.

Abstract
BACKGROUND Rheumatic manifestations were described soon after human immunodeficiency virus (HIV) was discovered. Since however, combination anti-retroviral therapy (cART) has revolutionized the course of the infection. Less clear is what effect cART has had on rheumatic manifestations. SOURCES OF DATA References were retrieved from the PubMed database using keywords including: 'HIV' and 'arthritis'; 'myalgia'; 'arthralgia' and other disease-specific terms, e.g. 'rheumatoid arthritis'. AREAS OF AGREEMENT Musculoskeletal pain was common in HIV and increased with AIDS. Immune restoration inflammatory syndrome on initiation of cART causes de novo autoimmune inflammatory rheumatic disorders. Seronegative inflammatory arthritis with/without axial involvement has been reported widely with HIV. AREAS OF CONTROVERSY It is unclear if HIV causes these conditions, creates an environmental milieu supportive of these conditions or acts as a marker of other risk factors. It is unclear what effect cART has had on these conditions. GROWING POINTS Variable diagnostic classification criteria have caused this literature to be poorly comparable. AREAS TIMELY FOR DEVELOPING RESEARCH High-quality controlled epidemiological studies using standardized criteria are needed among cART users. Treatment of active autoimmune disease in HIV patients needs to be evaluated formally.

Abstract
Although there are some studies suggesting relation between different types of infection and fibromyalgia syndrome (FM), there is presently no proof that FM is caused by an infection. Helicobacter pylori (HP) infection may cause extragastric manifestations. Inflammation is an important mediator of increased sympathetic nervous system activity and may lead to pain in fibromyalgia patients. In this study, we aimed to investigate the HP seropositivity in fibromyalgia patients compared with controls for possible role of HP infection in FM. Sixty-seven patients with fibromyalgia were evaluated. Two of them were excluded from the study because of high level of acute phase reactants. Sixty-five female patients with fibromyalgia and 41 randomly selected age-matched female healthy controls were enrolled to study. Serum HP IgA and IgG antibodies were measured by enzyme-linked immunosorbent assay technique. Fibromyalgia Impact Questionnaire was assessed in patients and controls. Seropositivity of HP IgG antibody in the fibromyalgia patients was significantly higher than in the control group. No statistically significant differences were found regarding the clinical features between fibromyalgia patients with HP IgG antibody and patients without IgG antibody. Our study suggests that former HP infection may have a role in the etiopathogenesis of fibromyalgia syndrome or may act as a triggering factor. However, high seroprevalence of HP in general population and prevalent asymptomatic infection make it difficult to interpret these results for the definite role of HP in FM. Highlighting the pathophysiologic mechanisms of FM will result in more effective treatment regimens.

Abstract
In this article, the authors discuss the occurrence and prevalence of rheumatic syndromes before and after highly active antiretroviral therapy became the usual mode of treatment. The immunologic, environmental, and genetic factors behind the combination of HIV infection and rheumatic manifestation contribute to the complexity of these diseases. Miscellaneous case reports are discussed in relation to HIV infection. The authors conclude that geriatric care of HIV patients is on the horizon as more people have access to newer, more effective therapy and mortality is on the decline. Younger HIV patients will be committed to a lifetime of therapy to address bone disease and other chronic problems. In the future, newer agents may steer the clinical scenario in unforeseen directions.

Abstract
This study was aimed to evaluate the seroprevalence of parvovirus B19 in patients with fibromyalgia syndrome (FS). Seventy-five patients with FS (44.3 +/- 8.3) and 75 healthy controls (44.2 +/- 8.1) were evaluated. Serum anti-B19 IgM and IgG antibodies were measured by ELISA technique. Patients were questioned about duration of symptoms, characteristic features of FS, and symptoms related with viral infection preceding the onset of FS. No significant difference was found regarding the prevalence of anti-B19 IgM antibodies between the groups (p = 0.494). Seropositivity of anti-B19 IgG of the patients was significantly higher than control group (81.3% vs. 64% respectively, p = 0.027). No statistically significant differences were found regarding to the clinical features between fibromyalgia patients with IgG antibody compared to those without IgG antibody. Parvovirus B19 IgG seropositivity was found to be significantly higher in patients with FS. Parvovirus B19 infection might have a role in the etiopathogenesis of FS or might act as a triggering factor.

Abstract
OBJECTIVE To write a systematic review on the etiology and pathophysiology of the fibromyalgia syndrome (FMS) and of chronic widespread pain (CWP). METHODS An interdisciplinary level-3 guideline (i.e. systematic literature search and assessment, logic analysis, formal consensus procedure) for the diagnosis and therapy of FMS was created in cooperation with 10 medical and psychological societies and 2 patient self-help organizations. A literature search was performed covering all available review articles on the etiology and pathophysiology of FMS and CWP using the Cochrane Collaboration Reviews (1993-12/2006), Medline (1980-2006), PsychInfo (1966-12/2006), and Scopus (1980-12/2006). For the assignment of evidence classes the system of the Oxford Centre for Evidence-Based Medicine was applied. Consensus was achieved by a multi-step nominal group procedure. RESULTS FMS aggregates in families (evidence level 2c). Physical and psychological stress at the workplace are risk factors for the development of CWP and FMS. Affective disorders are risk factors for the development and maintenance of FMS. Operant learning mechanisms and sensitization are risk factors for the chronification of FMS (evidence levels 2b). Several factors are associated with the pathophysiology of FMS, but the causal relationship is unclear. This includes alterations of central pain pathways, hyporeactivity of the hypothalamus-pituitary-adrenal axis, increased systemic pro-inflammatory and reduced anti-inflammatory cytokine profiles and disturbances in the dopaminergic and serotonergic systems. CONCLUSIONS FMS is the common final product of various etiological factors and pathophysiological mechanisms.

Abstract
The pandemic caused by the human immunodeficiency virus (HIV) has entered its second quarter-century, with 40 million people now affected worldwide - particularly in Africa, where the impact has been most devastating. A complex array of rheumatic disease manifestations has been described, including diseases specific to HIV infection such as HIV-associated arthritis and the diffuse infiltrative lymphocytosis syndrome; other conditions which occur prominently in HIV-positive individuals include vasculitis, reactive and psoriatic arthritis and HIV-associated polymyositis, opportunistic musculoskeletal infections, and finally disorders that were originally ameliorated by HIV infection, such as rheumatoid arthritis and lupus. Effective antiretroviral treatment ameliorates many of these disorders; however, the introduction of highly active antiretroviral treatment (HAART) has introduced a new spectrum of disorders and new challenges confronting the clinician, including osteonecrosis, rhabdomyolysis, and, with immune reconstitution, the appearance de novo of a variety of autoimmune disorders and phenomena.

Abstract
Rheumatic complaints are common in patients with HIV, and HIV positivity confers an increased susceptibility in populations with similar risk factors for HIV infection. With the advent of the modern combined antiretroviral treatment, HAART has had a profound beneficial effect on survival in HIV-infected patients, with lifelong control of HIV infection and normalization of life expectancy; but it has also contributed to both an altered frequency and a different nature of rheumatic complications now being observed in this population, with new rheumatic complications, such as osteoporosis, osteonecrosis, gout, mycobacterial, mycotic osteoarticular infections, and neoplasia perhaps more prevalent. Rheumatologists, internists, and general physicians need to be aware of these changes to provide optimal diagnosis and how to disclose the results to their patients. They also need to be familiar with the management of HIV infection and to direct careful attention to the prevention of HIV transmission in health care facilities.

Abstract
OBJECTIVE To review the pathophysiology of fibromyalgia syndrome. DESIGN Review of the literature available on Medline (1965-2001). RESULTS Fibromyalgia syndrome is a chronic pain syndrome that predominantly afflicts women. It is characterized by widespread pain, insomnia, fatigue, and the presence of multiple tender points. Despite intensifying research, the etiology of fibromyalgia has remained unclear. Importantly, neither infections, trauma, nor psychiatric abnormalities consistently precede the onset of pain in patients with this syndrome. There is, however, mounting evidence for central pain processing abnormalities in almost all fibromyalgia patients. These anomalies include hyperalgesia, allodynia, abnormal temporal summation of second pain, neuroendocrine abnormalities, and abnormal activation of pain-related brain regions. CONCLUSIONS Multiple abnormal findings in fibromyalgia patients strongly indicate a neuropathic pain syndrome, reminiscent of complex regional pain syndrome or postherpetic neuralgia. In addition, fibromyalgia syndrome seems to share similar characteristics with these neuropathic pain syndromes, including ineffective response to many analgesics.

Abstract
PURPOSE OF REVIEW Fibromyalgia Syndrome (FMS) is a chronic pain condition of unknown origin. Multiple abnormalities have been described, including peripheral tissue and central nervous system changes. The relation of these mechanisms, however, is likely bidirectional. FMS pain clearly depends on peripheral nociceptive input as well as abnormal central pain processing. This review will focus on the role of peripheral nociceptive input for pain in FMS. RECENT FINDINGS There is strong evidence for abnormal central pain processing in FMS. Sensitized spinal cord neurons in the dorsal horn are responsible for augmented pain processing of nociceptive signals from the periphery. In addition, glial activation, possibly by cytokines and excitatory amino acids may play a role in the initiation and perpetuation of this sensitized state. SUMMARY Nociceptive input clearly plays an important role in FMS. Acute or repetitive tissue injury has been associated with FMS pain. Cytokines related to such injuries may be responsible for long-term activation of spinal cord glia and dorsal horn neurons, thus resulting in central sensitization. A better understanding of these important neuro-immune interactions may provide relevant insights into future effective therapies.

Abstract
Chronic widespread musculoskeletal pain has been subjected to several epidemiological studies during the last decade. According to these, approximately 10% of the general population report such complaints, clearly indicating chronic widespread musculoskeletal pain as a major health problem in the Western world. Almost unanimously, all studies found higher rates of such complaints among women compared with men, but the mechanisms responsible for the skewed gender ratio remain unknown.Chronic widespread musculoskeletal pain is the clinical hallmark of fibromyalgia and has been the subject of numerous epidemiological studies. The prevalence of fibromyalgia is reportedly 3-5%, again with a significant female predominance. Although the aetiopathogenesis of both fibromyalgia and chronic widespread musculoskeletal pain without other features of fibromyalgia remains an enigma, there is a body of evidence suggesting psychological and sociocultural factors as important for contracting such pain syndromes.

Abstract
The purpose of this study was to determine the prevalence and correlates of fibromyalgia (FM) in a prospective, multiethnic systemic lupus (SLE) cohort. A total of 266 SLE patients with disease duration of < or = 5 years at study entry were evaluated longitudinally for the presence of FM (per ACR criteria). Sociodemographic factors, behavioral/psychological variables, clinical features, serologic factors (autoantibodies), and self-reported functioning (MOS SF-36) were ascertained in all patients. Subjects were evaluated at study entry and annually thereafter. The prevalence of FM was then calculated, as was the prevalence of FM-like manifestations (widespread pain with at least 6, but fewer than 11/18 tender points). Variables were evaluated for association with FM or FM-like manifestations by univariate and stepwise logistic regression analyses. FM was present in 14 patients (5%; 9/92 Caucasians (C), 4/109 African Americans (AA), 1/65 Hispanics (H)) and FM/FM-like manifestations in 35 (13%; 16 C, 9 AA, 10 H). There was no difference noted between those with and without FM with respect to gender, education level, income below poverty level, disease activity or damage. By stepwise logistic regression analyses, the strongest association with both FM and FM/FM-like manifestations was a self-reported history of anxiety or affective disorder (P = 0.0237, OR = 4.6 and P = 0.0068, OR = 3.4, respectively). Caucasian ethnicity was strongly associated with FM (P = 0.0066, OR = 7.5) and African American ethnicity was negatively associated with FM/FM-like (P = 0.0204, OR = 0.3). Poorer self-reported physical functioning was associated with FM/FM-like (P = 0.0443, OR = 0.96). FM and FM-like manifestations correlate best with the presence of Caucasian ethnicity, concomitant anxiety or affective disorder, and to a lesser extent with poorer self-reported physical functioning. African American ethnicity is negatively associated with the combination of FM and FM-like manifestations. Clinical measures of disease activity, disease damage, specific organ dysfunction, sociodemographic factors and serologic features are not correlated with FM in this early SLE cohort.

Abstract
Fibromyalgia is a chronic pain syndrome of unknown etiology characterized by diffuse pain and tender points, which have been present for more than 3 months. Many patients with systemic illnesses can have diffuse pain similar to that found in fibromyalgia, including rheumatic diseases such as polymyalgia rheumatica, rheumatoid arthritis, idiopathic inflammatory myopathy, systemic lupus erythematosus, and joint hypermobility. Osteomalacia and thyroid disease are also in the differential diagnosis of diffuse pain and are imminently treatable. In addition, there has been interest throughout the past 10 years in infectious diseases including hepatitis C, Lyme disease, coxsackie B, HIV, and parvovirus infection, which may cause or trigger fibromyalgia. This paper provides a framework to use when identifying these diseases as part of the evaluation of a patient with chronic widespread musculoskeletal pain.

Abstract
Fibromyalgia (FM), also known as fibromyalgia syndrome (FMS) and fibrositis, is a common form of nonarticular rheumatism that is associated with chronic generalized musculoskeletal pain, fatigue, and a long list of other complaints. Some have criticized the classification of FM as a distinct medical entity, but existing data suggest that individuals meeting the case definition for FM are clinically somewhat distinct from those with chronic widespread pain who do not meet the full FM definition. Clinic studies have found FM to be common in countries worldwide; these include studies in specialty and general clinics. The same is true of general population studies, which show the prevalence of FM to be between 0.5% and 5%. Knowledge about risk factors for FM is limited. Females are at greater risk, and risk appears to increase through middle age, then decline. Although some authors claim that an epidemic of FM has been fueled by an over-generous Western compensation system, there are no data that demonstrate an increasing incidence or prevalence of FM; moreover, existing data refute any association between FM prevalence and compensation. Claims that the FM label itself causes illness behavior and increased dependence on the medical system also are not supported by existing research. This article reviews the classification, epidemiology, and natural history of FM.

Abstract
Infective endocarditis (IE) is due to a microbial infection of the heart valves or of the endocardium in close proximity to either congenital or acquired cardiac defects. This infection is associated with a high risk of complications. Rheumatic manifestations are known to be frequent complications of IE. Controversy, however, frequently exists about the actual incidence of these complications. This may be due to the small number of series describing the frequency and type of rheumatic manifestations, the absence of uniform criteria used for the diagnosis of IE, and the fact that some studies on rheumatic manifestations in IE have been described from tertiary referral centers, which implicates associated problems of referral bias and uncertainty of denominator population. To investigate further the incidence, clinical spectrum, and outcome of patients with IE and rheumatic manifestations, we examined the features of patients diagnosed with clinically definite IE according to the Duke classification criteria at the single reference hospital for a defined population in northwestern Spain during a 12-year period. Between 1987 and 1998, 100 consecutive patients had 110 episodes of clinically definite IE. Rheumatic manifestations were observed in 46 of the 110 episodes (41.8%). As in other western countries, they occurred more commonly in men aged in their 50s. The most frequent valve involved was the aortic (43.5%) followed by the mitral valve (30.4%). Myalgia was a frequent symptom. Peripheral arthritis, generally as monoarthritis, was clinically evident in 15 cases (13.6%), and sacroiliitis in 1 patient. Low back pain was described in 14 cases (12.7%). Septic discitis was observed in 2 cases, and biopsy-proved cutaneous leukocytoclastic vasculitis was found in 4 cases. Other conditions such as trochanteric bursitis and polymyalgia were observed in 2 and 1 case, respectively. Apart from a significantly higher frequency of hematuria and a trend to lower serum complement levels in patients with rheumatic complications, no differences in clinical features, laboratory tests, or microbiologic blood culture results were found between cases with IE with or without rheumatic manifestations. Also, although patients with rheumatic manifestations had more embolic complications, the inhospital mortality rate in patients with rheumatic manifestations was not significantly different from that of the rest of the patients. The present study supports the claim that rheumatic complications are frequent in patients with clinically definite IE from southern Europe. The presence of musculoskeletal or vasculitic manifestations may be of some help, as warning signs, for the recognition of patients with severe disease who require rapid diagnosis and therapy.

Abstract
CONTEXT Although it has been known for over 15 years that a number of rheumatic diseases occur in patients with human immunodeficiency virus (HIV) infection, increasing knowledge about these disorders and advances in HIV treatment need to be considered in approaching patients with HIV-associated rheumatic disease. OBJECTIVE To examine the clinical, pathologic, and therapeutic features of HIV-associated rheumatic diseases in the context of what is known about the immunology of HIV infection. DATA SOURCES The author's own extensive collection of references, supplemented by PubMed Medline searches for articles in English-language journals published between 1985 and 2000. The indexing term HIV and the following coindexing terms were used for searching: arthritis, Reiter's syndrome, psoriatic arthritis, rheumatoid arthritis, osteonecrosis, vasculitis, pulmonary hypertension, myositis, myopathy, fibromyalgia, septic arthritis, parotid enlargement, diffuse infiltrative lymphocytosis syndrome, systemic lupus erythematosus, septic arthritis, mycobacterial arthritis, fungal arthritis, autoantibodies, anti-cardiolipin antibodies, and anti-neutrophilic cytoplasmic antibodies. STUDY SELECTION All papers identified in the literature search were reviewed. Studies presenting data that merely confirmed previous studies were not included in the analysis. DATA EXTRACTION All identified papers were abstracted by the author. Letters to the editor were included only if a new observation had been made. DATA SYNTHESIS This was a qualitative review of papers published, with new knowledge about these disorders summarized and presented. RESULTS Despite new treatments for HIV, reports of rheumatic diseases presenting in AIDS patients persist, especially in HIV-associated arthritis, diffuse infiltrative lymphocytosis syndrome, HIV-associated vasculitis, and polymyositis. However, new HIV treatments may ameliorate these diseases. CONCLUSIONS The spectrum of HIV-associated rheumatic disease remains a diagnostic and therapeutic challenge for the clinician. The impact of changes in HIV treatment on these disorders requires further assessment.

Abstract
We have encounted two patients with fibromyalgia (FM) initially diagnosed as having autoimmune fatigue syndrome (AIFS). To investigate the relationship between AIFS and FM, the distribution of the tender points in patients with AIFS was assessed according to the ACR criteria for FM. It was revealed that AIFS patients had 5.6 tender points on averages. Patients with headaches, digestive problems, or difficulty going to school had more tender points than patients without. Patients with ANA titers < 1: 160 had more tender points than patients with ANA > or = 1: 160. Anti-Sa negative patients had more tender points than positive patients. These results suggest a relationship between AIFS and FM in terms of the pathophysiologic mechanisms of the numerous tender points. In other words, ANA-positive FM patients could be one form of AIFS, as well as ANA-positive chronic fatigue syndrome patients. Thus, autoimmunity could explain the controversial disease entities of FM and/or CFS.

Abstract
To delineate the demographic features and clinical profile of male and female individuals utilizing a respite, rehabilitation and hospice centre in London, a retrospective study of patient notes was undertaken. The subjects were 59 male and 59 female HIV patients at first admission to the hospice. The study revealed clinically important differences between men and women and also identified special problems for African women and intravenous drug users. Women experienced more constipation, headache and musculoskeletal pain than men. Men suffered more neuropathic pain and visual loss. Lower respiratory tract infections were more common in women, especially in those with a history of injection drug use. Gynaecological morbidity was common. There was no difference in AIDS diagnoses between men and women. HIV encephalopathy developed in 23% of the cohort during the follow-up period which has implications for provider units. There are increasing numbers of HIV-positive women and injection drug users being referred for palliative care services. Multidisciplinary teams should be aware of the particular symptom profile of these groups.

Abstract
CFS and FM are clinical conditions characterized by a variety of nonspecific symptoms including prominent fatigue, myalgia, and sleep disturbances. There are no diagnostic studies or widely accepted, pathogenic, explanatory models for either illness. Despite remarkably different diagnostic criteria, CFS and FM have many demographic and clinical similarities. More specifically, few differences exist in the domains of symptoms, examination findings, laboratory tests, functional status, psychosocial features, and psychiatric disorders. FM appears to represent an additional burden of suffering among those with CFS, however, underscoring the importance of recognizing concurrent CFS and FM. Further clarification of the similarities (and differences) between CFS and FM may be useful in studies of prognosis and help define subsets of patients who may benefit from specific therapeutic interventions.

Abstract
Fatigue is widely recognized as a significant source of morbidity in persons with human immunodeficiency virus (HIV) infection, yet there are few data examining fatigue in this population. We present pilot data assessing the relationship between fatigue and various physical and psychosocial measures in 20 men with HIV infection prior to the clinical development of acquired immunodeficiency syndrome (AIDS). Fatigue was measured by a visual analogue scale (VAS) and the Fatigue Assessment Inventory (FAI). No statistically significant associations were found between fatigue measures and physical parameters including haemoglobin, haematocrit, albumin, total protein, and physical dimension score of the Sickness Impact Profile (SIP). The FAI correlated well with Beck's Depression Inventory and SIP-Psychosocial Dimension (r = 0.72 and 0.81, respectively; p < 0.001.) Both the FAI and VAS held moderate associations with the total SIP score. The SIP profile was similar to that observed in a sample of persons with chronic fatigue but without HIV infection, reported previously. Although the sample size is small, our data suggest a stronger association with psychosocial, rather than physical, parameters among persons with HIV infection and fatigue. The implications for clinical management and further research are discussed.

Abstract
Many different interventions have been studied in the therapy of fibromyalgia syndrome (Tables 1 and 2). While most have been effective, in general these trials have been short term. Furthermore, important or substantial improvement, when it has been assessed, occurs in only small proportions of patients. Long-term, comparative trials of both efficacy and toxicity are necessary. Trials such as these require large numbers of patients (compared with placebo-controlled trials, which are generally impractical in long-duration trials due to the large numbers of dropouts in the placebo arm) and therefore are expensive and difficult to accomplish. Two other approaches offer potential solutions to the problem of adequate long-term comparative trials: (a) N-of-1 trials and (b) meta-analysis. N-of-1 trials have the advantage of random assignment, double-blinding and multiple potential comparisons in the same patient. Meta-analysis involves combining the results of studies, which individually may have conflicting results and lack adequate statistical power, to reach an overall result with sufficient statistical power to make meaningful conclusions, especially with respect to comparative efficacy. Peluso and colleagues (1993) have performed a recent meta-analysis of available therapies in fibromyalgia syndrome and found that the effect-size (a standardized measure of the efficacy of a given therapy) of several non-medication therapies such as electroacupuncture exceeded that of traditional medication therapies. Unfortunately, lack of uniformity in the use of outcome measures across included trials and the small numbers of comparable non-medication trials makes definitive conclusions regarding relative efficacy of therapies difficult. Nevertheless, application of meta-analytic methods such as these should facilitate future comparisons of different interventions. Ideally, future clinical trials in fibromyalgia syndrome should employ the same outcome measures to permit application of these methods. Few trials have assessed improvement in functional status. Functional status measures such as the HAQ (Fries et al., 1980), the Fibromyalgia Impact Questionnaire (Burckhardt et al, 1991) or similar instruments should be employed in future studies of therapy in fibromyalgia. Given that individual modalities appear to confer relatively modest benefit on average. Combination approaches are reasonable, although randomized, blinded trials to assess these approaches are methodologically complex. Several preliminary studies which have addressed this approach appear promising (see Chapter 12; Goldenberg et al, 1993). Finally, no studies have yet assessed the comparative cost-efficacy of available treatments. Controlled trials which address the cost-efficacy of commonly employed, but unproven treatments such as physiotherapy chiropractic manipulation and injection techniques are urgently needed.

Abstract
OBJECTIVE To ascertain the prevalence of fibromyalgia syndrome (FMS) in systemic lupus erythematosus (SLE) and to evaluate its clinical impact and relationship to SLE disease activity. METHODS A cross-sectional analysis of 102 patients from a public hospital SLE clinic. Information was obtained on symptoms of FMS, disability, tender points, pain thresholds, and SLE disease activity. RESULTS Twenty-two SLE patients (22%) met the American College of Rheumatology criteria for FMS, and another 24 (23%) had clinical FMS but did not meet the classification criteria. The patients who met the criteria for FMS had a significantly increased frequency and severity of symptoms commonly associated with FMS, and were much more likely to be unable to perform daily activities. The FMS patients also were less likely to be employed, and more likely to be divorced and to be receiving welfare or medical disability benefits. However, patients with and those without FMS did not differ in measures of SLE activity. CONCLUSION FMS is very common in SLE patients, and accounts for many of the symptoms and much of the disability in these patients.

Abstract
Intravenous drug users present significant clinical challenges to internists. In this paper, we review common clinical dilemmas faced by internists when managing intravenous drug users in the inpatient hospital setting. Articles were identified through a MEDLINE search and bibliographies of published articles. Studies and reviews were selected for information relevant to the management of hospitalized intravenous drug users. Seventy-three papers were selected for this review. We summarize data and information from the relevant literature concerning common presenting medical problems (fever, musculoskeletal pain, and dyspnea), the importance of knowing patients' HIV status, common behavioral issues, special concerns of women, and the diagnosis and management of drug withdrawal in intravenous drug users. We also offer recommendations for hospital discharge planning. With appropriate knowledge of the epidemiology and management of important medical and substance use problems among intravenous drug users, internists may more effectively care for them in the hospital setting.
