A208 REAL WORLD EVIDENCE ANALYSIS WITH ADALIMUMAB BIOSIMILAR, MSB 11022, REPORTED WITH PATIENT CARE PROGRAM

Background

Injection site reactions (ISR), including injection site pain (ISP) are common adverse events reported with drugs administrated via subcutaneous injections. In clinical trials, the rates of ISR of adalimumab and adalimumab biosimilars range from 3% to 22.8% with citrate-buffer formulations, and from 1.7% to 16.6% with acetate-buffered and other formulations.

Purpose

The objective of this study is to evaluate ISR of adalimumab biosimilar, MSB 11022, in real world setting.

Method

Patients with immune mediated inflammatory diseases (IMIDs) enrolled with patient care program (PSP), and received at least one dose of adalimumab biosimilar, MSB 11022, were followed up. Incidences of injection site reactions, including injection site pain, burning sensation, bruise, erythema, hemorrhage, pruritus, and/or swelling were documented through unsolicited and solicited (outgoing following up calls with patients after their first injection through PSP contacts) reports. The data were collected between April 2021 and July 2022, and the rates of ISRs were assessed.

Result(s)

There were 2812 patients that met criteria through data collection period, with 219 cases of ISR. More than 99% of case reports were through solicited contacts, i.e., through case-manager follow up calls. Overall, rate of injection site reaction is 7.8% in patients with IMIDs treated with adalimumab biosimilar, MSB 11022. The rates of ISRs reported by disease are as follows: 6.8% of patients with Crohn's disease, 8.7% with ulcerative colitis, 8.8% with rheumatoid arthritis, 6.5% with psoriatic arthritis, 7.8% ankylosing spondylitis, 6.1% uveitis, 8.3% with hidradenitis suppurativa, and 11.1% of juvenile rheumatoid arthritis.

Conclusion(s)

Real world data provided evidence that ISR rate of adalimumab biosimilar, MSB 11022, is within the ranges of clinical trial data of adalimumab with citrate-buffer, and other formulations. As far as we know, this is the first real world evidence reported for ISR among adalimumab biosimilars with IMID patients.

Quality of life of Iranian and Afghan pregnant women in rural Iran

Background

Pregnancy is a unique experience in a woman's life, which comes with physiological, metabolic, social, and psychological changes. The combination of these changes along with migration, may reduce the quality of life of pregnant women and mothers. This study aims to determine the quality of life in rural pregnant women.

Methods

A cross-sectional study was conducted. Three hundred pregnant Iranian and Afghan women who attended the public health centers in regional Tehran, Iran, were systematically selected and included in the study. Different dimensions of health status were investigated using the standard health-related quality of life questionnaire (SF-26) through interviews. SPSS version 23 was used for data analysis.

Results

The psychological health subscale (38.00) in the Iranian pregnant women and the physical health subscale (38.83) in the Afghan pregnant women had the highest scores. The lowest score was in social functioning subscale in both groups (20.59 in Iranian and 21.22 in Afghans). In general, Iranian mothers had lower scores compared to Afghan mothers. There was a relationship between the quality of life of Iranian pregnant women, their level of education and family's monthly income (P <0.05), and between the quality of life of Afghan pregnant women with the lesser number of pregnancies (P <0.05).

Conclusions

In rural Iran, the quality of life score and its subscales is comparably low in both Iranian and Afghan pregnant women. Interventions are needed to improve the quality of life in this vulnerable population.

[Indications and techniques for intubation of the lacrimal ducts]

There are several well established methods to correct congenital and acquired lacrimal canalicular stenosis. The primary goal of all these surgical methods is the reopening and recanalization of a functional lacrimal pathway. Intubation by bicanalicular or monocanalicular silicone tubes has been established as a means of enhancing the redevelopment of a smooth epithelial surface and keeping the recanalized tear ducts continuously open. The use after endocanalicular surgery is mostly undisputed and unequivocally advocated after trauma but the use after either endonasal or transcutaneous dacryocystorhinostomy is still controversial as there is no clear evidence that it produces superior results. There are several systems available to place monocanalicular or bicanalicular silicone tubes. The decision to place an intubation depends mainly on the level and the type of stenosis.

[Lower lid entropion and ectropion. Indication, technique and key points of "classical" surgical methods]

Lower lid malposition is common, increases with age and leads to impaired optical function of the ocular surface through chronic irritation of the conjunctiva and cornea. Numerous techniques have been described to reposition the lid margin to the globe and secure this position while maintaining intact motility. Some of these techniques have passed the test of time and have reached the status of "classic" standard procedures that need to be in the armamentarium of every oculoplastic surgeon. The aim of this article is to consider the merits of a selection of standard methods for the correction of lower lid entropion and ectropion by describing their indication, technique and key points.

Comparing bone mineral density in postmenopausal women with and without vertebral fracture and its value in recognizing high-risk individuals

Vertebral fracture, the hallmark of osteoporosis, usually occurs in postmenopausal women with low bone mineral density (BMD). The aim this study was to determine which BMD parameter can best predict women at high risk of fracture. BMD values at the spine and femoral neck were compared in 34 women with vertebral fracture and 34 controls. Mean BMD (g/cm2), T-score, and Z-score values at both femoral neck and spine were significantly lower in the fracture than the nonfracture group. Z-score was more sensitive than BMD T-score for detecting low bone mass. T-score was not sensitive enough to identify low BMD in the spine, whereas the femoral neck T-score could recognize women at high risk of fracture with higher accuracy.

Severe tardy ulnar nerve palsy caused by traumatic cubitus valgus deformity: functional outcome of subcutaneous anterior transposition

Ten male patients with McGowan's grade III ulnar neuropathy due to traumatic cubitus valgus deformity underwent anterior subcutaneous ulnar transposition. Evaluation was performed using subjective and objective measures, and a modified Bishop score. After operation, subjective sensory and motor disturbances were improved or resolved in most of the patients, while objective measures improved less well. Improvement in two-point discrimination (2PD) was consistently associated with symptom relief. All of the patients reported satisfaction with the operation. There were no complications or recurrences. The results of ulnar nerve transposition in our patients were comparable to the results of this operation in patients with severe idiopathic cubital tunnel syndrome. Although the outcome of surgery is not always satisfactory in severe ulnar neuropathy, symptom relief may justify performing the operation.

Assessment of body mass index and hand anthropometric measurements as independent risk factors for carpal tunnel syndrome

The goal of this study was to clarify the role of body mass index (BMI) (weight divided by square of height; kg/m2) and hand anthropometric measurements as independent risk determinants in the development of carpal tunnel syndrome (CTS) and their relationship to the severity of CTS. A total of 131 patients with clinical symptoms of CTS and 131 normal subjects were enrolled, of whom 121 were female both in the CTS cases and the controls. All cases were electrodiagnostically confirmed and assigned to three severity groups. BMI, wrist ratio, shape index, digit index and hand length/height ratio were measured in all participants. Mean values for each item were compared between cases and controls and severity subgroups. A logistic regression analysis was performed to determine independent CTS risk factors. The mean values of BMI, wrist ratio and shape index were significantly higher in all CTS patients and females compared to controls, whereas in males only BMI and wrist ratio were higher. The patients in the mild severity subgroup had a significantly lower age and wrist ratio. BMI, wrist ratio and shape index were found to be independent risk factors of CTS development in all patients and females. Our study showed BMI, wrist ratio and shape index as independent risk factors for CTS. These findings are of potential anatomical and clinical importance and outline the risk factors of anatomical malfunction of the wrist in CTS.

Trapezoid supracondylar femoral extension osteotomy for knee flexion contractures in patients with haemophilia

Flexion deformity of the haemophilic knee is a considerable cause of disability and may need to be managed surgically in severe cases. We have used a trapezoid supracondylar femoral extension osteotomy to correct severe knee flexion deformity. Nine severe haemophilic patients with contractures >30 degrees that were unresponsive to conservative measures underwent 11 trapezoid osteotomies. The angle of deformity was measured using anteroposterior and lateral knee X-ray films at maximum extension. Factor levels of 80-100% were achieved before the operation. A trapezoid osteotomy of the distal femur bone was performed using a lateral approach. The frontal plane angular deformity (if any) was corrected at the same time. The osteotomy site was fixed using an Arbeitsgemeinschaft für Osteo synthesefragen (AO) condylar blade plate. Following surgery, the knee was supported by a plaster splint at 20 degrees of flexion. Physiotherapy was started on third postoperative day and continued three times a week. There was no serious complication. The deformities were corrected in all of the patients and the mean range of motion increased form 68.6 degrees to 98.1 degrees . Bleeding episodes decreased in all four knees which had a bleeding score of 3 before surgery. Using the Orthopaedic Advisory Committee of the World Federation of Haemophilia scores, nine good and two fair results were obtained. All patients regained the ability to walk for both short and long distance without any aid, climb the stairs, bath, and use public transportation. Trapezoid supracondylar femoral extension osteotomy should be considered in the surgical management of severe haemophilic flexion deformity of the knee joint.

Exudative pleural effusion: effectiveness of pleural fluid analysis and pleural biopsy

The study compared pleural fluid analysis and pleural biopsy in the diagnosis of 100 patients with exudative pleural effusion (PE) in Babol, Islamic Republic of Iran. Tuberculous pleurisy and malignant pleural effusion were confirmed by the identification of acid-fast bacilli from body fluids or tumour cells from tissue specimens. Malignant diseases and tuberculosis were the causes of exudative PE in 43% and 33% of patients respectively. The diagnostic sensitivity of pleural biopsy in patients with tuberculous PE and malignant PE was 70% and 54%, and the diagnostic sensitivity of pleural fluid analysis was 33% and 70% respectively. Combined pleural biopsy and pleural fluid analysis were positive in 97% of tuberculous PE cases and 91% of malignant PE.
