BACKGROUND: IgE-mediated cow's milk allergy (CMA) is one of the most common food allergies in infants. It is still controversial whether the early introduction of cow's milk formula (CMF) prevents the development of CMA. OBJECTIVE: We aimed to evaluate the duration and frequency of CMF ingestion as compere with exclusive breast-fed for preventing CMA in high-risk infants. METHODS: We enrolled the patients diagnosed with hen's egg allergy by an oral food challenge. A questionnaire was completed by the caregivers of the patients regarding the timing of introduction and discontinuation of CMF, and the frequency of CMF ingestion. Based on the information, we analyzed the relationship between the duration and frequency of CMF ingestion and the development of CMA at 3–24 months of age. RESULTS: Three hundred seventy-four patients were analyzed; 171 were diagnosed with CMA (45.7%). The analyzed patients (n = 374) were categorized into the following subgroups: exclusively breast-fed (breast-fed group, n = 75); discontinued ingestion of CMF before 3 months of age (temporary group, n = 177); continuous ingestion of CMF, but not daily, up to 3 months of age (nondaily group, n = 47); continuous ingestion of CMF at least once daily (daily group, n = 75). The incidence of developing CMA between the breast-fed group and temporary group did not show any statistical difference. Nondaily group and daily group had significantly lower incidence of developing CMA in comparison to the breast-fed group (nondaily group odds ratio 0.43; p = 0.02, daily group odds ratio 0.11; p < 0.001). CONCLUSION: Ingestion of CMF during the first 3 months of life might prevent the development of CMA in high-risk infants.

BACKGROUND: Oral food challenge (OFC) tests are conducted in both specialized institutions and general hospitals. We aimed to compare the severity of the conditions of the patients between these 2 types of institutions in order to consider the role of such institutions in society. OBJECTIVE: We evaluated the results of OFC tests for hen's egg, cow's milk, and wheat that were conducted in a specialized institution (Aichi Children's Health and Medical Center [ACHMC], n = 835) and in 4 general hospitals (n = 327) in Aichi prefecture, Japan. METHODS: The symptoms provoked were scored using the total score (TS) of the Anaphylaxis Scoring Aichi scoring system in combination with the total ingested protein dose (Pro) before the appearance of allergic symptoms. RESULTS: The total ingested dose of the challenge-positive patients in ACHMC was significantly less than that in the general hospitals (p < 0.01). The median TS of the provoked symptoms in ACHMC and the general hospitals did not differ to a statistically significant extent in the hen's egg or cow's milk challenges; however, the median TS in ACHMC was significantly lower than that in the general hospitals for the wheat challenge (p = 0.02). The median TS/Pro values in ACHMC were almost identical to the upper 25% of the TS/Pro values in the general hospitals, suggesting that the specialized institution usually managed more severe patients. CONCLUSION: The specialized institution performed OFC tests at a lower threshold dose, but provoked similar TSs to the general hospitals. This evaluation may help in optimizing the distribution of patients to general hospitals and specialized institutions.

Objectives: Locomotive syndrome (LS) leads to reduced physical function and a high risk of becoming bedridden.Grip strength serves as an indicator of upper limb and overall physical function. Rheumatoid arthritis (RA) patients with reduced grip strength frequently show finger and wrist joint inflammation. The purpose of this study was to verify grip strength as an evaluation tool for physical function and LS in RA patients. Methods: As part of an ongoing multicenter observational study, 591 consecutive RA patients whose background information was available, including data for the 25-question Geriatric Locomotive Function Scale (GLFS-25) and grip strength, were examined. LS was defined as a GLFS-25 score ≥ 16 points. Finger and wrist joint inflammation were defined as tender or swollen joints. Results: Among the 591 patients, 244 (41.3%) patients had LS, and 167 (28.3%) were male. Receiver operating characteristic curve analysis yielded cut-off values of grip strength for LS of 24 kg (specificity 72.2%; sensitivity 62.7%) for males and 17 kg (specificity 65.7%; sensitivity 67.6%) for females. Multivariable logistic regression analysis revealed a significant association of grip strength with LS, even after adjusting for finger and wrist joint inflammation. Conclusions LS was significantly associated with grip strength, even after adjusting for the presence of finger and wrist joint inflammation. We recommend adopting grip strength measurement as a screening tool for evaluating LS and guiding interventions.
