Prevalence of polypharmacy and drug interaction in older adults with rheumatic disease.

INTRODUCTION/AIM: Older people with rheumatic diseases tend to have a greater number of associated comorbidities, which will require the use of more drugs, increasing the risk of hospitalizations, complications, and drug interactions. In Mexico, there has been an estimated prevalence of polypharmacy of up to 55%, however there are scarce reports on the topic in our elderly population with rheumatic diseases. We aimed to determine the prevalence of polypharmacy and the association of drug interactions in patients treated for rheumatic disease. METHODS: A retrospective observational study was conducted on patients undergoing treatment for rheumatic diseases who were treated in geriatrics and rheumatology clinics from January to December 2021. The presence of polypharmacy and drug interactions was evaluated using the BOT Plus Pharmacological Surveillance System. The prevalence of polypharmacy and the association of drug interactions were estimated. RESULTS: We evaluated 320 patients, with a mean age of 67.05±5.8 years, predominantly female (85%). The prevalence of polypharmacy was 68.1% (n=218), of which 214 (98.1%) patients had related drug interactions; 27.1% were severe and 53.2% as moderate interactions. Factors related with increased risk of drug interactions were being exposed to hypertension increased the risk of drug interactions (POR 1.75, 95% CI 1.44-2.14; P<0.001), having osteoarthritis (POR 1.21, 95% CI 1.04-1.42; P=0.032) and thyroid disease (POR 1.45, 95% CI 1.28-1.65; P=0.001). The most prevalent serious interactions were leflunomide-methotrexate in 27 (46.5%) patients and buprenorphine-tramadol in 8 (13.7%). CONCLUSIONS: A high prevalence of polypharmacy and drug interactions was observed in elderly patients with rheumatic diseases. The main associated factors were comorbidities, particularly high blood pressure, osteoarthritis and thyroid diseases.

Update of the guidelines for the pharmacological treatment of rheumatoid arthritis by the Mexican College of Rheumatology 2023.

OBJECTIVE: To develop updated guidelines for the pharmacological management of rheumatoid arthritis (RA). METHODS: A group of experts representative of different geographical regions and various medical services catering to the Mexican population with RA was formed. Questions based on Population, Intervention, Comparison, and Outcome (PICO) were developed, deemed clinically relevant. These questions were answered based on the results of a recent systematic literature review (SLR), and the evidence's validity was assessed using the GRADE system, considered a standard for these purposes. Subsequently, the expert group reached consensus on the direction and strength of recommendations through a multi-stage voting process. RESULTS: The updated guidelines for RA treatment stratify various therapeutic options, including different classes of DMARDs (conventional, biologicals, and JAK inhibitors), as well as NSAIDs, glucocorticoids, and analgesics. By consensus, it establishes the use of these in different subpopulations of interest among RA patients and addresses aspects related to vaccination, COVID-19, surgery, pregnancy and lactation, and others. CONCLUSIONS: This update of the Mexican guidelines for the pharmacological treatment of RA provides reference points for evidence-based decision-making, recommending patient participation in joint decision-making to achieve the greatest benefit for our patients. It also establishes recommendations for managing a variety of relevant conditions affecting our patients.

Multicenter Study on the Frequency of Low Bone Mineral Density in Young Women With Breast Cancer and Associated Factors.

INTRODUCTION: Young women with breast cancer (BC) may experience bone mineral density (BMD) loss secondary to cancer treatment effects on estrogen levels. Studies assessing BMD in BC patients have had a limited representation of young women. This multicenter retrospective study analyzed the frequency of low BMD and associated factors in this age group. METHODS: Women diagnosed with stage 0-III BC at ≤40 years, treated with chemotherapy and/or endocrine therapy between 2010 and 2020 at 5 Mexican BC referral centers were eligible. Demographic, clinical and treatment data were collected, as well as bone dual-energy X-ray absorptiometry (DEXA) results. Low BMD was defined as lumbar or femoral neck T-score < -1.0 or Z-score ≤ -2.0. RESULTS: A total of 1259 patients were included; median age at diagnosis was 36 years (21-40). Overall, 93% received chemotherapy and 65% endocrine therapy (tamoxifen was received at some point by 61%, aromatase inhibitors by 17%, and GnRH agonists/bilateral oophorectomy by 21%). DEXA scans were documented in 254 (20%), of which 163 (64%; 95% confidence interval [CI] 58%-70%) had a low BMD report. Low BMD was associated with receiving aromatase inhibitors (Odds ratio [OR] 1.92; 95% CI 1.13-3.24), and GnRH agonists/bilateral oophorectomy (OR 2.25; 95% CI 1.21-4.21). CONCLUSION: The suboptimal frequency of BMD monitoring observed displays an alarming disregard for bone health in young patients. Thus, a high proportion of women with low BMD are potentially being missed and precluded from the opportunity to receive timely interventions. Particular focus should be put on BMD monitoring among patients treated with aromatase inhibitors, GnRH agonists or bilateral oophorectomy.

External validation of the 2017 ACR/EULAR classification criteria for inflammatory myopathies in a Mexican cohort: Role of autoantibodies in the diagnosis and classification of patients with inflammatory myopathies.

OBJECTIVE: This retrospective study aimed to perform the first external validation of the ACR/EULAR classification criteria for inflammatory myopathy (IIM) in a Mexican dynamic cohort where the patients were evaluated with clinical and laboratory values. As secondary objectives, we presented the clinical characteristics of the patients and included antibodies other than anti Jo1 to evaluate their impact on our population. METHODOLOGY: This study included 70 patients with IIM and 70 patients with differential diagnoses of IIM, according to the absolute score of the classification criteria. We obtained sensitivity and specificity in the modality without biopsy, and as an exploratory analysis, we added other antibodies from the myositis extended panel. We analyzed the area under the curve (AUC) of three models: score without antibodies, with anti Jo1 and with any antibody. RESULTS: The ACR/EULAR criteria showed increased specificity and at least similar sensitivity to that of the original cohort (85% sensitivity and 92% specificity), with a cohort point of >55%. When we classified patients into definite, probable, possible, and no IIM categories, by adding the extended myopathy panel, 6 of the 10 patients initially classified as "no IIM" changed their classification to "Probable IIM" and 4 to "Definite IIM"; of the 16 patients classified as "probable IIM," 15 changed their classification to "Definite IIM." CONCLUSION: Considering the limitations of this study, we concluded that the 2017 EULAR/ACR criteria for IIM classification are sensitive and specific for classifying patients with IIM in the Mexican population. Additionally, the addition of antibodies other than anti-Jo1 may improve performance in certain populations.

Clinical features of patients with hands arthralgia referred from primary care physicians to rheumatologists: A cohort study.

PURPOSE: Early referral of patients with suspicious of rheumatoid arthritis (RA) has an impact on prognosis. Our study aimed to evaluate the clinical characteristics of patients with hands arthralgia who were referred from primary care physicians (PCP) to the rheumatologist. METHODS: A descriptive, observational, prospective cohort study was performed. We included patients who visited a PCP for the first time for hands arthralgia. Demographics and the European Alliance of Associations for Rheumatology criteria for arthralgia suspicious for progression to RA plus seven complementary questions, the time to referral, the pressure needed to provoke pain with an automatic squeeze test machine in the metacarpophalangeal joints of both hands, and the diagnoses established at the last review of medical charts from patients on follow-up were documented. The primary outcome was the referral to a rheumatologist. RESULTS: A total of 109 patients were included. The mean age was 49.9 years, 81.6% were women. 30.3% were referred to the rheumatologist. The time to referral was a median of 38 days. The main clinical characteristics associated with referral to the rheumatologist were the "most severe symptoms are present after midnight" (OR=6.29) and the "difficulty with making a fist" (OR=3.67). An isolated "positive squeeze test of metacarpophalangeal joints" was not associated with a referral to the rheumatologist. CONCLUSIONS: Among patients with hands arthralgia who attended PCP, those with most severe symptoms after midnight and difficulty making a fist were more likely to be referred to the rheumatology clinic. Isolated positive squeeze tests are not a parameter for referral, it should only be performed if arthralgia is clinically suspected.

Comparison of Two Strategies for Hypercholesterolemia Detection through Point-of-Care Testing.

BACKGROUND: Childhood dyslipidemia is a common condition that can lead to atherosclerotic cardiovascular disease in adulthood. It is usually multifactorial. Screening for cholesterol disorders in children varies based on risk factors, with some guidelines recommending cascade screening for children with a clear family history of familial hypercholesterolemia, targeted screening for those with specific risk factors, and universal screening. Point-of-care testing (POCT) cholesterol tests offer potential advantages, including ease of use, portability, increased patient access, low cost, fewer medical or laboratory visits, and instant results. This study aimed to evaluate the effect of POCT cholesterol screening on the diagnosis of hypercholesterolemia in children in a family practice setting. METHODS: We used a POCT cholesterol analyzer to perform two different (universal and targeted) screening approaches for dyslipidemia in children. We used the NCEP guidelines for the classification of the results. RESULTS: We screened 183 children, 105 in the universal screening group and 78 in the targeted screening group. Eight patients in the targeted screening group had elevated cholesterol levels (p = 0.02). CONCLUSIONS: All participants received instant feedback and recommendations. Using a targeted screening approach, POCT could be a practical and effective tool for identifying at-risk children with hypercholesterolemia.

Are the cut-offs of the rheumatoid factor and anti-cyclic citrullinated peptide antibody different to distinguish rheumatoid arthritis from their primary differential diagnoses?

OBJECTIVE: Rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (anti-CCP) are commonly used for diagnosis of rheumatoid arthritis (RA), although other rheumatic diseases with arthritis can test positive. This study aimed to determine the cutoff values for RF and anti-CCP with the best diagnostic performance in a sample of patients with RA, compared with other rheumatic diseases. METHODS: This was a descriptive, prospective study. EUROINMMUN enzyme-linked immunosorbent assays for RF isotypes immunoglobulin (Ig) A (IgA), IgG and IgM and third-generation assay IgG for anti-CCP were used in serum samples of patients with RA, other rheumatic diseases and healthy subjects. The cutoff with the best diagnostic performance was determined by the Youden Index and receiver operating characteristic analysis Results: Three hundred and thirty-two serum samples were analysed. The cutoffs proposed in our population were for RF in RA patients versus other rheumatic diseases, and healthy subjects IgM 135 IU/mL, for each disease, compared with RA, were psoriatic arthritis (Psa) IgA 47.2 IU/mL, clinically suspicious arthralgia (CSA) IgA 39.5 IU/mL, primary Sjögren's syndrome (pSS) IgM 180.6 IU/mL, systemic lupus erythematosus (SLE) IgA 42.6 IU/mL, primary fibromyalgia (pFM) IgM 68.6 IU/mL, osteoarthritis (OA) IgM 48 IU/mL, gout IgM 117 IU/mL and healthy IgM 16.3 IU/mL. For anti-CCP, in RA patients versus other rheumatic diseases, and healthy subjects 6.95 IU/mL, for each disease, compared with RA, were Psa 6.8 IU/mL, CSA 9.95 IU/mL, pSS 20.7 IU/mL, SLE 6 IU /mL, pFM 11.8 IU/mL, OA 11.9 IU/mL, gout 5 IU/mL and healthy 5 IU/mL. CONCLUSION: Irrespective of the manufacturer's suggested cutoff, the RA versus differential diagnosis cutoffs must be considered.

Impact of obesity and overweight on C-reactive protein concentrations and disease activity in rheumatoid arthritis: A systematic review and meta-analysis.

AIM: This study aims to assess the association of obesity and CRP concentrations in adult patients with rheumatoid arthritis (RA), and its influence on measures of disease activity. METHODS: A comprehensive search was performed using Scopus, Web of Science, MEDLINE, and EMBASE, from the time of their inception to November 2021. Observational studies that evaluated the association between CRP concentrations and obesity or overweight in patients with RA were considered eligible. Correlation coefficients were pooled using the inverse variance method, while effect sizes were pre-calculated for adjusted standardized regression coefficients (ß). RESULTS: A total of 10 studies, which comprised 4024 patients, were included in this systematic review. Individually, most studies report a significant association between CRP concentrations and a higher body mass index or other adiposity measures, but the statistical significance was not sustained when pooling their data together. Through the estimates provided in the present review, it is noted that CRP tends to be more elevated in female patients with RA that have a higher BMI. However, this association is not present in men. CONCLUSION: CRP tends to be elevated in female patients with RA that have a higher BMI. Further research is required to assess this possible sex-related difference and to aid shared decision-making in order to avoid over-treatment and increased burden in patients with obesity and RA. PROSPERO registration number: CRD42022314580.

Bone erosions by MRI in first-degree relatives of patients with RA: an exploratory study.

INTRODUCTION/OBJECTIVES: First-degree relatives (FDR) of patients with rheumatoid arthritis (RA) are at increased risk of RA diagnosis. Magnetic resonance imaging (MRI) has been proposed as a useful tool to detect subclinical synovitis and bone abnormalities as predictors of progression to RA. The presence of grade ≥ 2 bone erosions in RA MRI scoring system (RAMRIS) was reported to be RA-specific. We aim to describe the prevalence and characteristics of MRI findings in RA patients and FDR. METHODS: A cross-sectional and exploratory study of 60 individuals was performed in 38 RA patients and 22 FDR with hand arthralgia without clinical arthritis and positive rheumatoid factor or anticitrullinated protein antibodies. All patients underwent an MRI and were evaluated for synovitis, bone erosion, and bone marrow edema. We evaluated second to fifth metacarpophalangeal joints of the dominant hand according to RAMRIS. RESULTS: Among the total population, eighteen (30%) subjects had grade ≥ 2 bone erosions, and 42 (70%) had at least one erosion of any grade. In patients with grade ≥ 2 bone erosions, 12 (31.6%) were from RA patients and 6 (27.2%) from FDR (p = 0.72). In patients with erosions of any grade, 26 (68.4%) were from RA patients and 15 (68.2%) were from FDR (p = 0.98). CONCLUSION: A high prevalence of bone erosions was found in RA patients' FDR who had symptoms without clinical arthritis and positive serology. MRI might be helpful in this population for an early detection of RA-specific erosions. The prognosis and the treatment decisions in these subjects should be elucidated. KEY POINTS: • First-degree relatives (FDR) of rheumatoid arthritis (RA) patients with positive serology and joint symptoms constitute a select subpopulation of individuals with an increased risk of developing RA. • Magnetic resonance imaging (MRI) of FDR shows a high prevalence of bone erosions of any grade, grade ≥ 2 erosions, and synovitis. • MRI might be helpful in FDR of RA patients to screen for the presence of RA-specific erosions or clinically undetectable synovitis.

Anti-carbamylated protein antibodies positivity and disease activity in Hispanic patients with established rheumatoid arthritis: An observational study.

OBJECTIVES: We aimed to determine the prevalence of anti-carbamylated protein (anti-CarP) antibodies in Mexican Hispanics with established rheumatoid arthritis (RA) and to assess their relationship with disease activity. METHODS: A cohort study was conducted in 278 patients with established RA during an 18-month follow-up. We measured IgG/IgM/IgA rheumatoid factor (RF), IgG anticitrullinated protein antibodies (ACPA) and IgG/IgM/IgA anti-CarP antibodies using enzyme-linked immunosorbent assay (ELISA). For disease activity, we performed the 28-joint disease activity score with erythrocyte sedimentation rate (DAS28-ESR). Repeated measures one-way ANOVA was used to test the association between anti-CarP IgG antibody status and longitudinal DAS28-ESR scores. Patients were evaluated at baseline and at 6, 12, and 18 months during follow-up. RESULTS: Anti-CarP IgG antibodies were positive in 47.8% of patients and, accounting for all isotypes, in 9.5% of patients with negative RF and ACPA. Triple antibody positivity was present in 42.6% of patients in our sample. Anti-CarP IgG antibody positivity did not show statistically significant differences in mean DAS28-ESR when compared to anti-CarP IgG antibody negative patients at baseline, 6, 12 or 18 months. CONCLUSION: Anti-CarP IgG antibodies are not associated to a higher disease activity in Hispanic patients with established RA. Our findings suggest that the clinical value of measuring anti-CarP antibodies in RA diminishes over time.

Comorbidity burden in terms of disability in patients with osteoarthritis in Mexico. The IMPACTAR registry.

OBJECTIVE: To determine the comorbidities associated with disability in patients with OA in Mexico (2013-2015). MATERIAL AND METHODS: A cross-sectional, retrospective and multicentre IMPACTAR study (n=7703) in Mexican patients (2013-2015). Comorbidities associated with disability were identified in 4971 patients diagnosed with OA from the IMPACTAR registry (n=7073). An adjusted logistic regression analysis was carried out by demographic, economic, clinical and medical variables. RESULTS: Mean age was 63 years; and 75% of the patients were women. Subjects with OA and presence of comorbidities are 42% more likely to develop disabilities than patients without associated comorbidity, considering age, sex, family income, OA diagnosis duration, and education level. The highest rate of people with disability (28.9%) was concentrated in Region 7, which corresponds to Mexico City. There are also significant differences between median family incomes, when the income of persons with disability is under $13 000 (IQR: 9000-16 000) Mexican pesos, compared to patients without disability. Almost half of the subjects (49.6%) reported having at least one comorbidity. Arterial hypertension was the risk factor with a statistically significant difference (32.8%) among those with disability (34.7%). CONCLUSIONS: Programs and interventions for OA patients should take into consideration comorbidity factors, being female, family income, and the region of residence as variables that may increase the possibility of developing an OA-associated disability.

Role of rheumatoid factor isotypes and anti-citrullinated peptide antibodies in the differential diagnosis of non-selected patients with inflammatory arthralgia.

BACKGROUND/OBJECTIVES: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by swelling, tenderness and destruction of synovial joints, leading to severe disability and premature mortality. The aim of the study was to determine the diagnostic accuracy of the 3 isotypes of rheumatoid factor (RF), anti-citrullinated peptide antibodies (ACPA) and the combination of both, for the diagnosis of rheumatoid arthritis (RA) in non-selected patients with inflammatory arthralgia. METHODS: We include 129 patients with inflammatory Arthalgia from a third level reference Center of rheumatic diseases in Monterrey, México. Their samples were analyzed for RF isotypes (IgA, IgG, and IgM) by ELISA (EUROINMUN), using a cut-off of 20IU/ml, and for ACPA's 5IU/ml; a medical examination was performed to obtain the definitive diagnoses of the patients. Data analysis was carried out using ROC curves for the measurement of sensitivity, specificity, for diagnostic accuracy to verify if the use of 3 RF isotypes and ACPA had a better prediction for the diagnosis of RA than use only one isotype and the ACPA alone. RESULTS: The ROC showed a sensitivity and specificity of the different antibodies with different cut-off points, being the best for the IgM with 0.802 followed by ACPA, IgA and IgG with 0.771, 0.63, and 0.728 respectively without statistical difference, the sensitivity and specificity of the combination of the 4 antibodies were 81.4 and 73.66%. CONCLUSION: In non-selected patients with inflammatory arthralgia, the combination of ACPA and isotypes of RF did not demonstrate more sensibility and specificity than IgM isoform of rheumatoid factor measurement only. We recommend that in the clinical scenario of arthralgia, where the diagnoses are Lupus, Sjogren syndrome and Osteoarthritis, RF IgM isoform is used followed by ACPA.

High frequency of rheumatic regional pain syndromes in first-degree relatives of patients with rheumatoid arthritis.

First-degree relatives (FDR) of patients with rheumatoid arthritis (RA) have a higher risk for the development of RA. In the stages prior to the development of arthritis, nonspecific musculoskeletal (MSK) manifestations may occur. The aim of the study is to describe the frequency of rheumatic regional pain syndromes (RRPS) in FDR of RA patients. A cross-sectional study was carried out from July 2016 to September 2018. Parents, offspring, and siblings of RA patients completed the Community Oriented Program in the Rheumatic Diseases (COPCORD) questionnaire. Rheumatoid factor (RF) IgG, IgM, and IgA; anticitrullinated peptide antibodies (ACPAs); C-reactive protein (CRP); and erythrocyte sedimentation rate (ESR) were determined. All subjects with a positive COPCORD (defined by the presence of musculoskeletal pain) were evaluated and classified. Three hundred thirty-five FDRs participated, 75.8% were female, mean age of 44.15 years; 138 (41.2%) were diagnosed with at least one RRPS; 72 (21.5%) had rotator cuff tendinitis, 51 (15.2%) pes anserine bursitis, and 39 (11.6) lateral epicondylitis; RA was diagnosed in 24 (7.16%) subjects, undifferentiated arthritis (UA) in 30 (8.9%) and inflammatory arthralgia (AI) in 104 (31%). We found anti-CCP positivity in 6.8%, RF IgA in 22.3%, RF IgM in 48.6%, and RF IgG in 8.9%. The presence of RRPS was higher in this RA-FDR group compared to general population. Clinical evaluation of this risk group should include screening for RRPS.

Levels of satisfaction with rheumatoid arthritis treatment and associated alignment between physicians and patients across Latin America.

INTRODUCTION: Discordance (misalignment) regarding treatment satisfaction may exist in real-life clinical practice between patients and their physicians. We aimed to assess physician and patient treatment satisfaction levels and associated degree of misalignment in rheumatoid arthritis (RA). METHOD: A point-in-time, multinational survey of patients and physicians was conducted in Latin America from December 2014 to October 2015. Physician- and patient-reported satisfaction levels with current RA treatment, alignment levels in satisfaction perception, and factors associated with satisfaction misalignment were assessed through bivariate and logistic regression analyses. RESULTS: Participating physicians (N = 114) completed 555 patient record forms (PRFs); 372 patients completed self-complete questionnaires (PSC). A total of 346 physician-patient pairs were analyzed. Physicians reported satisfaction with current disease control in 270/346 (78.0%) PRFs; patients reported such satisfaction in 286/346 (82.7%) PSCs. Physician-patient alignment was observed in 78.6% of pairs. Compared with aligned patients, misaligned patients were younger, more likely to have moderate or severe disease (physician subjectively defined), deteriorating or unstable disease (physician subjectively defined), been exposed to a greater number of advanced therapy lines (biologic or Janus kinase inhibitor), greater current pain, a current acute episode, poorer health, and greater disability and impairment. Misaligned patients were less likely to be in remission. Logistic regression analysis revealed that misaligned patients were more likely to experience greater activity impairment. CONCLUSIONS: High treatment satisfaction and alignment were observed among RA patients and their physicians in Latin America. Misaligned patients were more likely to report more severe disease and were less likely to be in remission. Addressing misalignment may lead to improved RA disease control.Key Points• High treatment satisfaction was observed among RA patients and their treating physicians in Latin America.• One-fifth of physician-patient pairs were misaligned in treatment satisfaction.• Patients misaligned with their physicians reported higher disease activity, lower quality of life, and greater disability than those who were aligned with their physicians.• Understanding and addressing misalignment in treatment satisfaction may improve outcomes in this patient population.

Physician-patient alignment in satisfaction with psoriatic arthritis treatment in Latin America.

INTRODUCTION: Physician-patient misalignment may exist in real-life clinical practice. We aimed to assess physician and patient treatment satisfaction levels and associated degree of misalignment in psoriatic arthritis (PsA). METHOD: Data from a cross-sectional survey of patients and their physicians conducted in Latin America were analyzed. Physician-reported and patient-reported satisfaction levels with current PsA treatment, alignment in satisfaction levels, and factors associated with satisfaction misalignment were assessed through bivariable and multivariable regression analyses. RESULTS: A total of 179 physician-patient pairs were analyzed. Physicians reported satisfaction with current disease control in 87.7% (n = 157) of cases; patients reported satisfaction in 91.1% (n = 163 of cases). A total of 82.1% of physician-patient pairs were aligned. Compared with aligned patients, misaligned patients were older and more likely to have moderate or severe disease, deteriorating or unstable disease, a past hospital procedure, current or past psoriasis symptoms, greater current pain, a current acute episode, poorer health and quality of life, greater impairment, poorer medication compliance, to consider PsA a major daily burden, and to believe that PsA treatments were ineffective. Misaligned patients were less likely to be in remission. Logistic regression analysis revealed that misaligned patients were older, and more likely to consider PsA a major daily burden and PsA treatments as ineffective. CONCLUSIONS: High levels of treatment satisfaction and alignment were observed among PsA patients and their physicians in Latin America. Patients in this study nevertheless experienced a considerable clinical and quality-of-life burden, especially the misaligned patients. Addressing misalignment may lead to improved PsA disease control.Key points• High treatment satisfaction was observed among PsA patients and their treating physicians in Latin America.• Patients experienced a considerable clinical and quality-of-life burden, especially the misaligned patients.• One-fifth of physician-patient pairs were misaligned regarding satisfaction.• Understanding and addressing misalignment may improve outcomes in this patient population.

Esophageal symptoms and their lack of association with high-resolution manometry in systemic sclerosis patients.

BACKGROUND: The esophageal involvement in systemic sclerosis (SSc) causes impact in the morbidity and mortality. High resolution manometry assesses esophageal involvement. Our aim was to categorize esophageal motor disorder in patients with SSc by HRM. METHODS: We carried out an observational, descriptive and cross-sectional study. All patients underwent HRM as well as semi-structured interviews to assess frequency and severity of upper GI symptoms. Patients also completed the gastroesophageal reflux questionnaire (Carlsson-Dent). RESULTS: We included 19 patients with SSc, 1 with morphea, and 1 with scleroderma sine scleroderma. Dysphagia and heartburn were the most frequent symptoms (61% each). We found an abnormal HRM in 15 (71.4%) patients. We found no statistically significant association between clinical or demographic variables and an abnormal HRM, or between any upper GI symptom and HRM findings. CONCLUSION: We observed a high prevalence of esophageal symptoms and of HRM abnormalities. However, there was no clear association between symptomatology and HRM findings. HRM does not seem to accurately predict upper GI symptomatology.
