Health-Related Quality of Life and Psychosocial Variables in Women with Colorectal Pelvic Floor Dysfunction: A Cross-Sectional Study.

Pelvic floor dysfunction comprises various disorders, including urinary incontinence, fecal incontinence, pelvic organ prolapse, and chronic pelvic pain. This study aimed to evaluate health-related quality of life (HRQoL), anxiety, depression, sleep disturbance, and sexual functioning in women with pelvic floor dysfunction of colorectal etiology compared with control women. Patients were recruited from a specialized colorectal unit and controls were selected from among the patients' friends and relatives. Sociodemographic and clinical data were collected. Pelvic floor dysfunction distress and impact, HRQoL, depression, anxiety, insomnia, and sexual functioning were assessed using the following validated questionnaires: Short-Form Pelvic Floor Distress Inventory (PFDI-20), Short Form Pelvic Floor Impact Questionnaire (PFIQ-7), 36-Item Short-Form Health Survey (SF-36), Beck Depression Inventory II (BDI-II), Beck Anxiety Inventory (BAI), Insomnia Severity Index (ISI), and Changes in Sexual Functioning Scale (CSFQ). Statistical analyses included Welch's t-test, Fisher's exact test, and Spearman's correlation coefficients. Eighty-four patients and 57 controls were included. Compared with controls, patients were more likely to be obese or overweight, have had higher numbers of deliveries, more vaginal deliveries, more frequent use of forceps, and have had more associated comorbidities, mainly in the urinary, neurological, and psychiatric domains. As expected, patients scored significantly higher than controls on both the PFDI-20 and PFIQ-7 and their respective sub-scales, with the highest mean values in the patient group on the sub-scales related to the colorectal-anal domain. QoL, depression, anxiety, insomnia, and sexual functioning were significantly worse in patients than in controls (p < 0.0001 in every case). In patients, PFIQ-7 scores correlated significantly with HRQoL (p < 0.001 for the physical component and p < 0.01 for the mental component), depression (p < 0.001), anxiety (p < 0.001), insomnia (p < 0.05), and sexual functioning scores (p < 0.05). Colorectal pelvic floor dysfunction had a markedly deleterious impact on the HRQoL, depression, anxiety, sleep disturbance, and sexual functioning of patients. It is concluded that colorectal pelvic floor dysfunction exerts a considerable burden on patients' lives. Addressing these issues in clinical settings could significantly improve patients' well-being.

Psychosocial Variables and Healthcare Resources in Patients with Fibromyalgia, Migraine and Comorbid Fibromyalgia and Migraine: A Cross-Sectional Study.

Fibromyalgia and migraine frequently coexist. We aimed to compare the burden caused by fibromyalgia (FM), migraine (M) and comorbid fibromyalgia and migraine (FM + M) by assessing psychosocial variables and the use of healthcare resources. A survey was posted to the websites of different patients' associations. It included sociodemographic data, the Patient Health Questionnaire-9, the Insomnia Severity Index, the EuroQOL-5D-5L and a questionnaire evaluating the use of healthcare resources during the past six months. In total, 139 FM patients, 169 M patients and 148 FM + M patients participated in the survey. Mean depression and insomnia scores were clinically relevant in every group and significantly higher in FM + M (16.3 ± 5.4 for depression, 18.5 ± 5.6 for insomnia) than in FM (14.3 ± 5.7 for depression, 16.8 ± 5.5 for insomnia) or M (11.7 ± 5.4 for depression, 13.1 ± 5.9 for depression), where p < 0.001 in both cases. Suicidal ideation was frequent in every group, but significantly more frequent in FM + M (63% vs. 45% in FM and 35% in M; p < 0.001). EQ-5D-5L (0.656 ± 0.1 in FM + M, 0.674 ± 0.1 in FM, 0.827 ± 0.1 in M, p < 0.001) and EQ-5D-5L VAS scores (38.2 ± 21.9 in FM + M, 45.6 ± 21.8 in FM, 63.5 ± 23.7 in M, p < 0.00) were lower than the reported mean population values and the lowest in FM + M. FM and FM + M used more healthcare resources than M. It is concluded that the psychosocial burden was high in the three samples. FM and FM + M had a more relevant impact on patients' wellbeing and required more medical attention than M. The burden caused by FM + M was higher than in both individual diseases.

The Probiotic VSL#3® Does Not Seem to Be Efficacious for the Treatment of Gastrointestinal Symptomatology of Patients with Fibromyalgia: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

Gastrointestinal symptomatology is frequent among patients with fibromyalgia, which increases disease burden and lacks specific treatment, either pharmacological or non-pharmacological. We aimed to evaluate the efficacy and tolerability of a multi-strain probiotic, VSL#3®, for the treatment of fibromyalgia-associated gastrointestinal manifestations. This randomized, placebo-controlled trial included 12 weeks of probiotic or placebo treatment followed by 12 weeks of follow up. The primary outcome variable was the mean change from the baseline to the endpoint in the composite severity score of the three main gastrointestinal symptoms reported by patients with fibromyalgia (abdominal pain, abdominal bloating and meteorism). Secondary outcome variables were the severity of additional gastrointestinal symptoms, fibromyalgia severity, depression, sleep disturbance, health-related quality of life and patients' overall impression of improvement. No differences were found between VSL#3® (n = 54) and the placebo (n = 56) in the primary outcome (estimated treatment difference: 1.1; 95% confidence interval [CI]: -2.1, 4.2; p = 0.501), or in any of the secondary outcomes. However, responders to VSL#3 were more likely to maintain any improvement during the follow-up period compared to responders in the placebo arm. Overall, VSL#3 tolerability was good. Our data could not demonstrate any beneficial effects of VSL#3® either on the composite score of severity of abdominal pain, bloating and meteorism or in any of the secondary outcome variables. More research is needed to elucidate specific factors that may predict a favourable response to treatment in patients with fibromyalgia.

Marital Adjustment in Patients with Cancer: Association with Psychological Distress, Quality of Life, and Sleep Problems.

Marital adjustment plays a key role in the physical and psychosocial wellbeing. We conducted a cross-sectional study to evaluate marital adjustment and its association with psychological distress, suicidal ideation, sleep problems, and quality of life in patients with cancer. We collected demographic and clinical information using a structured survey. We assessed marital adjustment, quality of life, psychological distress profile, and sleep problems of participants using validated instruments: the Locke and Wallace Marital Adjustment Test (LWMAT), the Short-Form Health Survey-12, the Beck's Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and the Insomnia Severity Index (ISI). Suicidal ideation was assessed with item nine of the BDI. Of the 130 patients (52.3% females, mean age 57.9 ± 12.4 years) enrolled, 20 (15%) were classified as experiencing poor marital adjustment. Moderate to severe depression, anxiety, and insomnia were found in 25.4%, 34.6%, and 24.7% of participants, respectively. Positive suicidal ideation was documented in 13.8% of participants. We found a significant association between poor marital adjustment and depression, anxiety, suicidal ideation, and poor sleep. Our study confirms the relevance of marital adjustment in relation to the psychological wellbeing of patients with cancer. Depression, anxiety, and poor sleep were found to be significantly associated with poor marital adjustment.

Dietary habits in patients with fibromyalgia: a cross-sectional study.

OBJECTIVES: To the scarce information on dietary habits in fibromyalgia (FM), it is added that there are no comparative studies with other rheumatic diseases. The objective of this study was to characterise the dietary habits of patients with FM by comparing, for the first time, with healthy controls (HC) and rheumatoid arthritis (RA). METHODS: This cross-sectional, observational study was based on data obtained from the Dietfibrom project for FM and from the IMID Consortium for RA and HC. All participants completed a food frequency questionnaire evaluating their weekly dietary intake of main food groups. The three cohorts were compared using a multiple logistic regression model adjusted for age, sex, and body mass index. RESULTS: After quality control, n=287 FM, n=1,983 HC and n=1,942 RA patients were analysed. We found that FM had a profound impact in the diet compared to HC, reducing the consumption of dairy (OR=0.32, p<0.0001), bread and/or whole grain cereals (OR=0.59, p=0.0006), fresh fruit (OR=0.66, P=0.008), and fish (OR=0.64, p=0.002). These same four food groups were also significantly reduced in FM patients in comparison to RA patients (p<0.0005 in all cases). Additionally, a lower consumption of pasta, rice and/or potatoes was also observed in FM compared to RA (OR=0.72, p=0.028). CONCLUSIONS: The present cross-sectional study shows that FM is associated to a significant change in the normal dietary patterns. These results underscore the importance of diet in this prevalent disease and are a warning of the potential long-range effects of a deficient nutritional status.

Marital adjustment in patients with fibromyalgia: its association with suicidal ideation and related factors. A cross-sectional study.

OBJECTIVES: Fibromyalgia has been associated with suicidal ideation, suicide attempts and completed suicide. Non-married status is a risk factor for suicidal behaviours but the quality of the marital relationship has been scarcely investigated. The objectives of the present study were to evaluate, in patients with fibromyalgia, the relationship between marital adjustment suicidal ideation and potentially related variables: depression severity, sleep disturbance, perceived burdensomeness, thwarted belongingness, fibromyalgia severity and pain intensity. METHODS: A survey was done in patients with fibromyalgia which collected sociodemographic data and included the following questionnaires: the Locke and Wallace Marital Adjustment Test, the Beck's Depression Inventory II, the Plutchik Suicide Risk Scale, a 10-item version of the Interpersonal Needs Questionnaire, the Insomnia Severity Index, and the Revised Fibromyalgia Impact Questionnaire. Suicidal ideation was assessed with item 9 of the Beck's Depression Inventory, and pain intensity was measured with the VAS scale of the Revised Fibromyalgia Impact Questionnaire. RESULTS: Of 257 participants 71 were single, 107 had a good marital adjustment and 79 a poor marital adjustment. Suicidal ideation was most frequent among patients with poor marital adjustment than among those with good marital adjustment or patients without partner. The poor marital adjustment group showed significantly worse scores in most of the remaining variables with the only exceptions of the FIQR and pain scores. CONCLUSIONS: In patients with fibromyalgia the degree of marital adjustment seems to be a relevant factor for suicidal ideation and related variables.

Patterns of pharmacologic and non-pharmacologic treatment, treatment satisfaction and perceived tolerability in patients with fibromyalgia: a patients' survey.

OBJECTIVES: To evaluate the patterns of treatment among patients with fibromyalgia (FM) in Spain and to assess patient satisfaction and perceived tolerability of the treatment received. METHODS: An observational, cross-sectional study was conducted in Spain via internet from September 2015 to March 2017. We recorded sociodemographic and clinical information, including treatment satisfaction evaluated using a 10-point numerical rating scale (NRS) and adverse events. RESULTS: Evaluable subjects (n=915) were predominantly middle-aged, married women who presented with moderate to severe pain, sleep disturbance and affected quality-of-life. The most frequent non-pharmacologic treatments were physical exercise (85%), diet (47%), supplements such as magnesium and vitamins (47%), and psychotherapy (31%). The most frequently prescribed drugs were tramadol (40%), benzodiazepines (30%), duloxetine (22%), pregabalin (19%), amitriptyline (17%) and nonsteroidal anti-inflammatory drugs (NSAIDs; 16%); 7.5% of patients received stronger opioids. After excluding benzodiazepines, NSAIDs, and paracetamol, 46% of patients received ≥2 drugs. Satisfaction with treatment (NRS mean score) was generally poor for pharmacologic treatment (4.1), exercise (4.7), psychotherapy (5.2), diet (5.0), physiotherapy (6.2) and acupuncture (6.3). The increase in the number of drugs prescribed was not associated with an increase in satisfaction, but rather with an increase in adverse events. CONCLUSIONS: Patients with FM in Spain are overtreated with a combination of non-pharmacologic and pharmacologic therapies. Several of these therapies lack adequate support from randomised clinical trials and/or clinical practice guidelines. This overtreatment is not associated with relevant clinical benefits or patient satisfaction and, in the case of pharmacologic treatments, poses tolerability and safety issues.

Suicidal Ideation Profiles in Patients with Fibromyalgia Using Transdiagnostic Psychological and Fibromyalgia-Associated Variables.

Several studies have emphasized the heterogeneity of fibromyalgia patients. Furthermore, fibromyalgia patients are considered a high-risk suicide group. The ideation-to-action framework proposes a set of transdiagnostic psychological factors involved in the development of suicidal ideation. The present study aims to explore the existence of different subgroups according to their vulnerability to suicidal ideation through these transdiagnostic psychological variables and a set of variables typically associated with fibromyalgia. In this cross-sectional study, 151 fibromyalgia patients were assessed through the Revised Fibromyalgia Impact Questionnaire, Beck Depression Inventory-II, Plutchik Suicide Risk Scale, Interpersonal Needs Questionnaire, Defeat Scale, Entrapment Scale, Psychache Scale, and Beck Hopelessness Scale. A K-means cluster analysis identified two clusters, one (45.70%) according to a low vulnerability, and a second (54.30%) with a high vulnerability to suicidal ideation. These clusters showed statistically significant differences in suicidal ideation and suicide risk. However, no differences were observed in most socio-demographic variables. In conclusion, fibromyalgia patients who present a clinical condition characterized by a moderate-high degree of physical dysfunction, overall disease impact and intensity of fibromyalgia-associated symptoms, along with a high degree of perceived burdensomeness, thwarted belongingness, defeat, entrapment, psychological pain and hopelessness, form a homogeneous group at high risk for suicidal ideation.

Clustering a large Spanish sample of patients with fibromyalgia using the Fibromyalgia Impact Questionnaire-Revised: differences in clinical outcomes, economic costs, inflammatory markers, and gray matter volumes.

The main objective of this study is to identify fibromyalgia syndrome (FMS) clusters using the Revised Fibromyalgia Impact Questionnaire (FIQR), and to examine whether the clusters differ in sociodemographic characteristics, clinical measures, direct and indirect costs, levels of inflammatory markers, and brain morphometry. A hierarchical cluster analysis was performed to classify a large, pooled Spanish sample of patients with FMS (N = 947) using the FIQR as clustering variable. A latent profile analysis was subsequently conducted to confirm the optimal number of FMS clusters. To examine external validity, a battery of clinical measures, economic costs, inflammatory markers, and gray matter volumes of relevant cortical and subcortical areas were analyzed. We also compared the discriminant validity of the clusters with the original FIQR severity categories. To promote the implementation in real-world clinical practice, we built a free online cluster calculator. Our findings indicated that a four-cluster solution more clearly captured the heterogeneity of FIQR data and provided the best fit. This cluster solution allowed for detection of differences for most clinical outcomes and economic costs. Regarding the inflammatory and brain-based biomarkers, differences were found in C-reactive protein, and tendencies were found in the right medial prefrontal cortex, the right parahippocampal gyrus, and the right middle cingulate cortex; brain regions associated with executive functions and pain processing. The original FIQR categories presented similar results, although their precision in discriminating among the nonextreme categories (ie, moderate and severe) was not sound. These findings are discussed in relation to previous research on FMS clustering.

Psychiatric Comorbidity in Children and Adults with Gluten-Related Disorders: A Narrative Review.

Gluten-related disorders are characterized by both intestinal and extraintestinal manifestations. Previous studies have suggested an association between gluten-related disorder and psychiatric comorbidities. The objective of our current review is to provide a comprehensive review of this association in children and adults. A systematic literature search using MEDLINE, Embase and PsycINFO from inception to 2018 using terms of ‘celiac disease’ or ‘gluten-sensitivity-related disorders’ combined with terms of ‘mental disorders’ was conducted. A total of 47 articles were included in our review, of which 28 studies were conducted in adults, 11 studies in children and eight studies included both children and adults. The majority of studies were conducted in celiac disease, two studies in non-celiac gluten sensitivity and none in wheat allergy. Enough evidence is currently available supporting the association of celiac disease with depression and, to a lesser extent, with eating disorders. Further investigation is warranted to evaluate the association suggested with other psychiatric disorders. In conclusion, routine surveillance of potential psychiatric manifestations in children and adults with gluten-related disorders should be carried out by the attending physician.

Pelvic floor dysfunction in women with fibromyalgia and control subjects: Prevalence and impact on overall symptomatology and psychosocial function.

AIMS: To evaluate the prevalence, distress, and impact of pelvic floor dysfunction (PFD) symptomatology in women with fibromyalgia and control women. We also aimed to evaluate the impact of PFD symptomatology on several psychosocial measures such as mood, sleep, pain, and quality of life. METHODS: We conducted a cross-sectional study in women with fibromyalgia and control women from the general population. Using a structured survey, we collected sociodemographic and clinical data, assessed the prevalence of PFD and evaluated the distress (PFDI-20) and the impact (PFIQ-7) caused by its symptomatology. Using Spanish-validated questionnaires, we also evaluated mood and sleep disturbances, bodily pain, and quality of life in subjects with and without PFD. In participants with fibromyalgia, we assessed the severity and impact of the disease using the Fibromyalgia Impact Questionnaire (FIQR). RESULTS: Two hundred and twenty-six patients with fibromyalgia and 222 control women completed the surveys. Two hundred and twenty patients (93%) and 140 controls (63%) reported PFD-related symptoms. Both the scores of distress (143.1 ± 5.7 vs 96.1 ± 4.8, P < 0.0001) and impact (122.4 ± 5.6 vs 100.6 ± 6.4, P < 0.0001) caused by PFD symptoms were significantly higher in women with fibromyalgia than in controls. There was a significant positive relationship between fibromyalgia severity and both PFDI-20 (r2 = 0.32, P < 0.0001) and PFIQ-7 scores (r2 = 0.375, P < 0.0001). Depression severity, sleep disturbances, bodily pain, and low quality of life were highest in women with fibromyalgia and PFD and lowest in control women without PFD. CONCLUSIONS: PFD-related symptoms were significantly more frequent in women with fibromyalgia than in controls. PFD symptomatology, when present, negatively influenced mood, sleep quality, and quality of life of both patients with fibromyalgia and controls.

Perceived burdensomeness, thwarted belongingness and suicidal ideation in patients with fibromyalgia and healthy subjects: a cross-sectional study.

Perceived burdensomeness and thwarted belongingness are key factors in the development of suicidal behaviors that have been frequently observed among patients with fibromyalgia. The aim of the present study was to compare these two factors in patients with fibromyalgia with and without suicidal ideation and healthy subjects. Secondary objectives were to evaluate the relationship between these two factors and the secondary variables included in the study, such as depression, sleep quality or the degree of marital adjustment. Perceived burdensomeness and thwarted belongingness were assessed with the Interpersonal Needs Questionnaire, depression and suicidal ideation with the Patients Health Questionnaire-9, suicidal risk with the Plutchik Suicide Risk scale, sleep with the Insomnia Severity Index, and marital adjustment with the Locke-Wallace Marital Adjustment scale. Questionnaire scores were compared with the Kruskal-Wallis test. 49 healthy subjects, 38 patients with fibromyalgia without suicidal ideation and 15 patients with fibromyalgia and suicidal ideations were included. Perceived burdensomeness scores were significantly higher in patients with suicidal ideation than in patients without suicidal ideation and controls; thwarted belongingness scores were significantly higher in patients with suicidal ideation than in controls. Marital adjustment was also significantly poor in patients with suicidal ideation than in patients without suicidal ideation and controls. Among patients with fibromyalgia, perceived burdensomeness seems to be strongly related with suicidal ideation, whereas thwarted belongingness seems to play a less relevant role at this respect. Poor marital adjustment could be related with depression.

Psychometric properties of the Spanish version of the 12-item Interpersonal Needs Questionnaire in fibromyalgia syndrome patients / Propiedades psicométricas de la versión en español del Cuestionario de Necesidades Interpersonales de 12 ítems en pacientes con síndrome de fibromialgia

According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness are key elements in the development of suicidal ideation. The Interpersonal Needs Questionnaire (INQ) was developed to assess the degree of frustration of these two interpersonal needs related to suicidal ideation. This study aims to analyze the psychometrics properties of a Spanish adaptation of INQ-12 in fibromyalgia patients. Exploratory factor analysis (n = 180) and confirmatory factor analysis (n = 179) were performed in two randomly selected subsamples. The first analysis leads to the elimination of two items, whereas the second one confirmed the fit of the proposed two-factor structure. The reliability estimated using the Cronbach's alpha coefficient and the Spearman-Brown coefficient was adequate. To obtain further validity evidence based on the relationship with other variables three variables were used. Moreover, a control group (n = 99) was used to contrast the means of INQ scores as evidence of validity based on differential scores. These findings support the usefulness of the Spanish version of the INQ-10 for assessing the degree of frustration of these interpersonal needs in patients with fibromyalgia

Según la teoría interpersonal del suicidio, la pertenencia frustrada y la carga percibida son elementos clave en el desarrollo de la ideación suicida. El Cuestionario de necesidades interpersonales (INQ) fue diseñado para evaluar el grado de frustración de estas dos necesidades interpersonales relacionadas con la ideación suicida. El objetivo de este estudio fue analizar las propiedades psicométricas de una adaptación al español del INQ-12 en pacientes con fibromialgia. Un análisis factorial exploratorio (n = 180) y un análisis factorial confirmatorio (n = 179) fueron realizados en dos submuestras seleccionadas al azar. El primer análisis llevó a la eliminación de dos ítems, mientras que el segundo confirmó el ajuste de la estructura propuesta de dos factores. La fiabilidad estimada mediante el coeficiente alfa de Cronbach y el coeficiente Spearman-Brown fue adecuada. Para obtener evidencias de validez basadas en la relación con otros variables, se utilizaron tres variables relacionadas con el suicidio. Además, se utilizó un grupo control (n = 99) para contrastar los promedios de las puntuaciones INQ como evidencia de validez basada en puntajes diferenciales. Estos hallazgos respaldan la utilidad de la versión española del INQ-10 para evaluar el grado de frustración de estas necesidades interpersonales en pacientes con fibromialgia

Suicidal behaviors in patients with rheumatic diseases: a narrative review.

Chronic rheumatic disorders are characterized by inflammation and chronic pain, and both anxiety and depression have been frequently observed in these patients. Depression and chronic pain are recognized as risk factors for the development of suicidal behaviors. Accordingly, the objective of the present review is to provide a comprehensive review of suicidal behaviors associated with rheumatic diseases. Medline and EMBASE were searched for English language publications using key words related with rheumatic diseases, suicide, suicide attempts, and suicidal ideation. 34 records (30 full-length published papers and 4 studies published in abstract form) that included data related to the frequency and/or potential determinants of suicidal behaviors in rheumatic diseases were included in the review. It was found that both suicidal ideation and completed suicide seem to be more frequent in patients experiencing systemic lupus erythematosus, fibromyalgia and arthritis. Major determinants were comorbid depression in fibromyalgia and arthritis, and neuropsychiatric disease in systemic lupus erythematosus. Based on these findings, suicide risk should be assessed in patients suffering from systemic lupus erythematosus, fibromyalgia and/or arthritis.

The Effects of a Gluten-free Diet Versus a Hypocaloric Diet Among Patients With Fibromyalgia Experiencing Gluten Sensitivity-like Symptoms: A Pilot, Open-Label Randomized Clinical Trial.

BACKGROUND AND AIMS: Patients with fibromyalgia frequently present with symptoms similar to those experienced by patients with gluten-related disorders, raising the possibility that a subgroup of these patients could be experiencing underlying gluten sensitivity. This study aimed to evaluate the effects of a gluten-free diet (GFD) compared with a hypocaloric diet (HCD) among patients with fibromyalgia. METHODS: Adult patients diagnosed with fibromyalgia were randomly allocated to receive a GFD or a HCD over a 24-week period. The primary outcome measure was the change in the number of gluten sensitivity symptoms. The following secondary outcomes were evaluated: body mass index, Revised Fibromyalgia Impact Questionnaire, Pittsburgh Sleep Quality Index, Brief Pain Inventory, Beck Depression Inventory-II, State-Trait Anxiety Inventory, Short-Form Health Survey, Patient Global Impression Scale of Severity, Patient Global Impression Scale of Improvement, and adverse events. RESULTS: Seventy-five subjects were randomly allocated to receive either a GFD (n=35) or an HCD (n=40). The least squares mean change in the total number of gluten sensitivity symptoms from baseline did not differ significantly between the GFD and HCD groups (-2.44±0.40 for the GFD; -2.10±0.37 for the HCD; P=0.343). Similarly, the 2 dietary interventions did not differ in any of the remaining measured secondary outcomes. Both dietary interventions were well tolerated. CONCLUSIONS: Both dietary interventions were associated with similar beneficial outcomes in reducing gluten sensitivity symptoms and other secondary outcomes. However, despite its specificity, GFD was not superior to HCD in reducing the number of gluten sensitivity symptoms or secondary outcomes.

Alpha2delta ligands, gabapentin, pregabalin and mirogabalin: a review of their clinical pharmacology and therapeutic use.

INTRODUCTION: The first two alpha2delta ligands - gabapentin (GBP) and pregabalin (PGB) - were initially synthesized as antiepileptics; however, they were later also found to be useful for the treatment of additional conditions. Areas covered: Relevant publications describing potential underlying mechanisms, clinical pharmacokinetics/pharmacokinetics, and clinical efficacy and safety of these drugs in various disease conditions were searched in PubMed and Scopus and included in this review. Expert commentary: GBP and PGB are effective for the treatment neuropathic pain, fibromyalgia and epilepsy; in addition, they may be useful for the reduction of postoperative pain. PGB is also effective for the treatment of generalized anxiety disorder and GBP for the treatment of restless legs syndrome. GBP may be considered a treatment option for pain associated with Guillain-Barré Syndrome and phantom limb and for the management of uremic pruritus. Mirogabalin (MGB), recently developed, is being investigated for the treatment of peripheral neuropathic pain and fibromyalgia, showing promising results in patients with diabetic peripheral neuropathy. Their most frequent adverse reactions are of neuropsychiatric nature and include fatigue, dizziness, sedation, somnolence, and ataxia; peripheral edema and weight gain are also frequently described. Pharmacokinetic interactions are scarce; however, pharmacodynamic interactions have been described in association with drugs with CNS-depressant effects.

Amitriptyline for the treatment of fibromyalgia: a comprehensive review.

Fibromyalgia is characterized by chronic generalized pain accompanied by a wide range of clinical manifestations. Most clinical practice guidelines recommend multidisciplinary treatment using a combination of pharmacological and non-pharmacological therapies. The tricyclic antidepressant amitriptyline has been most thoroughly studied in fibromyalgia. Amitriptyline has been evaluated in placebo-controlled studies, and it has served as an active comparator to other therapeutic interventions in the treatment of fibromyalgia. In addition, several systematic reviews and meta-analyses have evaluated its efficacy and safety for the treatment of fibromyalgia. Data from individual studies as well as from systematic reviews indicate that low doses (10-75 mg/day) of amitriptyline are effective for the treatment of fibromyalgia and, despite the limited quality of the data, they do not seem to be associated with relevant tolerability or safety issues. Consistent with some clinical guidelines, we believe amitriptyline in low doses should be considered a first-line drug for the treatment of fibromyalgia.
