Objective: To study evolution of pSS immunological profile, impact on pSS activity and the long-term evolution of patients with atypical auto-antibodies in a bicentric cohort of patients with pSS (n=445, mean age 53.6+/-14years, mean follow-up 76.1+/-51months).
Results: 212 patients were SSA positive and 131 were both SSA and SSB positive. During follow-up, SSA antibodies disappear in 8 patients; 2 of them exhibit new systemic complications of pSS. 68 patients had cryoglobulinemia. 52 patients had other anti-nuclear antibodies (ANA) specificities: anti-RNP (n=12), anti-centromere (n=14), anti-DNA native (n=19), anti-Scl70 (n=3), anti-JO1 (n=3), anti-Sm (n=3) and anti-histone (n=1). Fourteen patients developed ANA-associated auto-immune disease during the follow-up: 5 polymyositis (mean apparition delay 78months), 6 systemic lupus erythematosus (mean occurrence delay 77months) and 2 systemic sclerosis (mean occurrence delay 133+/-64months). Among these 14 patients, only three presented atypical-ANA at pSS diagnosis. Cryoglobulinemia and anti-SSA and SSB antibodies at diagnosis were associated with new systemic involvements.
In Conclusion: Cryoglobulinemia and SSA/SSB positivity are associated with systemic activity after diagnosis in pSS. Although atypical ANA are found in 12% of the cases, long-term evolution to ANA associated auto-immune diseases concerned patients with active immunological profile and extra-glandular manifestations.

Use of immunomodulating agents to prevent the progression of autoimmune β-cell damage leading to type 1 diabetes mellitus (T1DM) is an interesting area for research. These include non-specific anti-inflammatory agents, immunologic vaccination and anti-inflammatory agents targeting specific immune cells or cytokines. Teplizumab is an anti-CD3-molecule that binds to and leads to the disappearance of the CD3/TCR complex and rendering the T cell anergic to its target antigen.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse manifestations, requiring long-term treatment that can have side effects, particularly in pediatric patients. has shown potential for improving SLE symptoms due to its anti-inflammatory and immunomodulatory effects. The aim of this study was to investigate the immunomodulatory effect of oil (NSO) on disease activity, T lymphocyte activity and inflammatory cytokine profiles in pediatric SLE patients.

Background: Nocturnal cough affects approximately 1 in 3 children, can negatively impact child health, and is often attributable to asthma. The association of the gut microbiome with nocturnal cough has not been investigated.
Objective: To investigate the association between early-life gut microbiome composition and nocturnal cough overall and in the context of asthma.

Background: Limited data exist on bictegravir pharmacokinetics in pregnancy among persons with HIV (PWH) and infant washout.
Setting: Nonrandomized, open-label, multi-center phase-IV prospective study of bictegravir pharmacokinetics and safety in pregnant PWH and their infants.
Methods: Steady-state 24-hour pharmacokinetic sampling of oral bictegravir 50 mg once daily (a component of fixed-dose combination bictegravir/emtricitabine/tenofovir alafenamide) during the 2nd and 3rd trimesters and postpartum was performed.

Background: The presented study identified the appropriate ocrelizumab dosing regimen for patients with pediatric-onset multiple sclerosis (POMS).
Methods: Patients with POMS aged 10-17 years were enrolled into cohort 1 (body weight [BW] < 40 kg, ocrelizumab 300 mg) and cohort 2 (BW ≥ 40 kg, ocrelizumab 600 mg) during a 24-week dose-exploration period (DEP), followed by an optional ocrelizumab (given every 24 weeks) extension period.
Primary Endpoints: pharmacokinetics, pharmacodynamics (CD19 B-cell count); secondary endpoint: safety; exploratory endpoints: MRI activity, protocol-defined relapses, Expanded Disability Status Scale (EDSS) score change.
