Advantage of the Subcutaneous Immunoglobulin Replacement Therapy in Primary Immunodeficient Patients With or Without Secondary Protein Loss

In recent years subcutaneous immunoglobulin is widely used for primary immunodeficient patients. Subcutaneous administration provides a more stable and higher serum immunoglobulin levels due to continuous and steady transition from lymphatics to the systemic circulation. We aimed to evaluate the changes in serum immunoglobulin levels under subcutaneous immunoglobulin therapy in patients with primary immunodeficiency with or without secondary protein loss. Nine patients with primary immunodeficiency who switched to subcutaneous immunoglobulin were enrolled. Age, gender, diagnosis, reasons of transition to subcutaneous route, reasons of secondary protein loss were recorded. A questionnaire consisting of frequencies and types of infections, side effects observed with intravenous and subcutaneous routes; date and reason of transition to subcutaneous route were asked to all participants. Serum immunoglobulin levels at the 3rd and the 6th months before and after subcutaneous route were recorded. Of the 9 patients (M/F=4/5) the median age was 12 years (6.1-28.7) and 5 of them had protein loss. In total, 444 injections were applied, and all patients experienced local reactions. Infections were more frequent under intravenous than subcutaneous route (p=0.004). We observed an increase in immunoglobulin levels under subcutaneous route (p=0.069 at 3rd; p=0.13 at 6th month). This increase was evident at the 3rd month of transition to subcutaneous route in patients with protein loss (p=0.080). There was an increase in serum immunoglobulin levels under subcutaneous route. However, increase was not statistically significant since the study group was small. This increment was prominent in patients with protein loss. Subcutaneous administration may be a good alternative for primary immunodeficient patients with protein loss who have persistent low serum immunoglobulin levels despite increments in the intravenous immunoglobulin doses

Proposal for a simple algorithm to differentiate adult-onset Still's disease with other fever of unknown origin causes: a longitudinal prospective study

Objective: To identify several clinical and/or laboratory parameters which can differentiate adult-onset Still's disease (AOSD) from other causes of fever of unknown origin (FUO) and create a clinician-friendly algorithm for this purpose. Methods: FUO patients hospitalized between March 2015 and September 2017 were recruited prospectively. AOSD patients diagnosed between 2001 and 2017 in our department were analyzed. Clinical and laboratory parameters were recorded for all patients. A multivariate analysis was performed to identify possible parameters related to the discrimination of AOSD from FUO. Results: We recruited 69 AOSD patients (51 females, 74%) and 87 patients (43 females, 49.4%) evaluated for FUO. Median ages were 45 (30-57) and 45 (30-62), respectively. Arthralgia, rash, sore throat, neutrophilia, serum ferritin level higher than 5 times of the upper limit, and elevated lactate dehydrogenase levels were associated with the likelihood of diagnosing AOSD; on the other hand, the number of daily fever peaks equal or greater than 3 was associated with the unlikelihood of diagnosing AOSD. After the clinical feasibility assessment of possible parameters derived from the multivariate analysis, in the setting of fever, two clinical (arthralgia, sore throat) and two laboratory (ferritin level, neutrophilia) parameters were selected to develop an algorithm for discrimination of AOSD and FUO. Conclusion: Presence of arthralgia, hyperferritinemia, sore throat, and neutrophilia suggests AOSD in patients presenting as FUO. This study proposes a clinician-friendly algorithm for the first time in current literature to discriminate AOSD from other causes of FUO.PubMe

Response rate of initial conventional treatments, disease course, and related factors of patients with adult-onset Still's disease: Data from a large multicenter cohort

WOS: 000374919900006PubMed ID: 26970681Background: Adult-onset Still's disease (AOSD) is a rare condition, and treatment choices are frequently dependent on expert opinions. The objectives of the present study were to assess treatment modalities, disease course, and the factors influencing the outcome of patients with AOSD. Methods: A multicenter study was used to reach sufficient patient numbers. The diagnosis of AOSD was based on the Yamaguchi criteria. The data collected included patient age, gender, age at the time of diagnosis, delay time for the diagnosis, typical AOSD rash, arthralgia, arthritis, myalgia, sore throat, lymphadenopathy, hepatomegaly, splenomegaly, pleuritic, pericarditis, and other rare findings. The laboratory findings of the patients were also recorded. The drugs initiated after the establishment of a diagnosis and the induction of remission with the first treatment was recorded. Disease patterns and related factors were also investigated. A multivariate analysis was performed to assess the factors related to remission. Results: The initial data of 356 patients (210 females; 59%) from 19 centers were evaluated. The median age at onset was 32 (16-88) years, and the median follow-up time was 22 months (0-180). Fever (95.8%), arthralgia (94.9%), typical AOSD rash (66.9%), arthritis (64.6%), sore throat (63.5%), and myalgia (52.8%) were the most frequent clinical features. It was found that 254 of the 306 patients (83.0%) displayed remission with the initial treatment, including corticosteroids plus methotrexate with or without other disease-modifying antirheumatic drugs. The multivariate analysis revealed that the male sex, delayed diagnosis of more than 6 months, failure to achieve remission with initial treatment, and arthritis involving wrist/elbow joints were related to the chronic disease course. Conclusion: Induction of remission with initial treatment was achieved in the majority of AOSD patients. Failure to achieve remission with initial treatment as well as a delayed diagnosis implicated a chronic disease course in AOSD. (C) 2016 Elsevier Ltd. All rights reserved
