The safety of teriparatide has been studied in various phase III and phase IV trials. However, a postmarketing study of the biosimilar of teriparatide, CinnoPar®, has not been conducted on Iranian patients. This was a phase IV study conducted on osteoporotic patients who received an Iranian teriparatide biosimilar with a dose of 20 μg daily. The primary outcome of this study was to monitor for adverse events (AEs). Effectiveness as the secondary outcome was measured using the EQ-5D quality-of-life questionnaire and back pain Visual Analogue Scale (VAS) score. Among 193 analyzed patients between September 2015 and March 2019, the most common AEs were hypercalcemia (4%), nausea, and pain (3%). No deaths, serious AEs, or other significant AEs occurred in this study. The mean EQ-5D scores decreased after the course of the treatment from 2.3 ± 0.66 at the baseline to 2 ± 0.66. The mean back pain VAS scores also decreased from 4.9 ± 3.6 at baseline to 1.8 ± 2.1 at the end of the study. Both changes were statistically significant (p < 0.001). Consistent with the findings of previous studies and the drug monograph, no new safety concern was observed with this biosimilar teriparatide, and the drug was effective based on the VAS score and EQ-5D in osteoporotic patients.

Background/aim: Studies have shown that anticyclic citrullinated peptide antibody (anti-CCP) titers can be useful in the diagnosis of rheumatoid arthritis (RA). We evaluate the association between anti-CCP antibody titers and the demographic, clinical, and laboratory characteristics of RA patients. Moreover, we explore whether there is any relation between joint destruction and demographic and clinical characteristics of RA patients. Materials and methods: One hundred and four RA patients with positive anti-CCP titers were compared to 104 RA patients with negative anti-CCP titers. The activity of RA was evaluated using the Disease Activity Score 28 (DAS28). Joint destruction was assessed in the subjects by X-rays of the wrists. Blood samples were collected for assessment of anti-CCP, rheumatoid factor (RF), and erythrocyte sedimentation rate. Results: Forty-eight (23.0%) males and 160 (76.9%) females were included in this study. RF, DAS28, and joint destruction were significantly different between patients with and without anti-CCP (P < 0.0001). DAS28, duration of disease, hospitalizations, and occupation differed significantly between patients with and without joint destruction (P < 0.0001). Conclusion: This study indicates that anti-CCP is correlated with a high disease activity index and more joint destruction in RA patients and it may be used as a prognostic factor for RA.

Sjogren syndrome (SS) can occur alone, primary Sjogren syndrome, or in association with other rheumatic diseases, secondary Sjogren syndrome (sSS), such as Rheumatoid arthritis (RA). The occurrence of Sjogren syndrome with RA makes it course worse and increases high morbidity and mortality of RA. In this exploratory study we aim to determine the prevalence of sSS (diagnosed based on the revised version of American-European consensus Group Classification Criteria: AUCG-criteria), sicca symptoms (dry eye, dry mouth), positive autoantibody tests (Anti RO or Anti-LA antibodies), UWSFR (Unstimulated Whole Salivary Flow Rate), Schirmer and Lissamine test. In this cross-sectional study, eighty three consecutive RA patients (according to American College of Rheumatology criteria 1987) who were visited at rheumatology clinic of Razi General Hospital located in the north of Iran entered into our study. Our exclusion criteria was a positive history of past head and neck radiation treatment, Hepatitis C infection, acquired immunodeficiency disease (AIDS), pre-existing lymphoma, sarcoidosis, graft versus host disease, use of anticholinergic drugs (including neuroleptics, antidepressants, antihypertensive and parasympatholytics). They examined with UWSFR by a rheumatologist and with Schirmer test and Lissamine test by an ophthalmologist. Participants were 90.4% female with the mean age 48.3±13 years. Duration of RA was in 36.1% less than 5 years, in 22.9% 5-10 years, in 12.1% 11-15 years and in 28.9% more than 15 years. Our results demonstrated that the prevalence of sSS was 5.9% (CI:0.6%-10.5%). Number of 27.7% of RA patients positively responded to at least one question about sicca symptoms. Among objective tests, only Positive UWSFR and Lissamine test were significantly more common in RA patients with sSS in comparison to ones without sSS (P<0.001, P=0.01 respectively). In RA patients, we found a linear trend between sicca symptoms and aging (P=0.02). In patients with sicca symptoms, among tests that used for assessing decrease in saliva or tear production, only USWFR significantly more common (P=0.01). In conclusion: In RA population in North of Iran prevalence of sSS was less than 10%. In them, a significant linear trend existed between aging and sicca symptoms. Among objective tests of AUCG-criteria (except for lip biopsy that was not performed in the current study) only UWSFR and Lissamine test were significantly more common in patients with sSS in comparison ones without it.

Background: The Sjogren syndrome (SS) is the least well-known rheumatic condition. We aim to gradually resolve it by standardizing the process of SS care in our country, at first for primary Sjogren syndrome cases, through developing Iran Primary Sjogren Syndrome Registry (IRAPSS) which will create a representative and comparable data bank., Methods: Guilan Primary Sjogren Syndrome Registry (GUIRAPSS) is a pilot phase of IRAPSS, which is a prospective cohort. Care of its patients is done based on EULAR Sjögren's syndrome disease activity index (ESSDAI) recommendations. Other IRAPSS outcome measurements are EULAR Sjogren syndrome patient reported index (ESSPRI) and Sjögren's syndrome disease damage index (SSDDI) for detecting disease damage., Results: Female-male ratio was 17.5. The age at expert diagnosis was 46.97 ± 11.93 years old. The most common comorbidity was hypothyroidism (28.38%), followed by musculoskeletal conditions (27.02%). 28.38% had fatigue. Active disease existed based on the clinical form of ESSDAI and ESSDAI, 31.8% and 81.8% respectively. The most involved organs during disease activity based on ESSDAI were biological 68.12% following pulmonary (12.16%) and respiratory (10.81%) system. Hydroxychloroquine was the most prescribed drug (72.97%), followed by prednisolone (28.38%)., Conclusion: Disease registries provide an ideal opportunity for gathering standardized and comparable data which provides needed items for creating, updating, or adapting pSS classification criteria/diagnosis, outcome measurements and or treatment guidelines., Competing Interests: The authors declare that they have no competing interests., (© 2024 Iran University of Medical Sciences.)

Objectives: To compare fibromyalgia (FM) core symptoms, FM impact severity and health status between the recently defined type A and type B of fibromyalgia. To compare disease impact and health status between FM patients and non-FM chronic pain control group. Finally, to compare health related quality of life and disease symptom severity by demographic background and widespread pain index (WPI)., Methods: A total of 284 consecutive FM patients and 96 non-FM control patients were enrolled. The information of four questionnaires including the Fibromyalgia Survey Questionnaire (FSQ), the Fibromyalgia Impact Questionnaire (FIQ), the 12-item Short Form Health Survey (SF-12) and questionnaires regarding demographic features were collected from a local FM registry., Results: Of all FM patients, 102 (94%) and 7 (6%) were type A and B, respectively. We found statistically significant differences in symptomatology, the FIQ scores and the SF-12 subscales across two type and control groups (p<0.001). However, when we compared these scores pairwise, except WPI there were no significant differences in other scores between type A and B. Also, there were no significant differences in FIQ and SF-12 scores across different age or educational status groups. Interestingly, patients with higher WPI had significantly higher FIQ (overall, symptom, and total) scores, worse PCS-12 and MCS-12 scores, and vice versa., Conclusions: Type B constitutes a minor but important component of FM that probably has a marked impact on the patient's perceived illness severity and quality of life. Further, WPI probably is the most important single indicator of disease severity and quality of life in FM.
