INTRODUCTION: Acute tubulointerstitial nephritis (ATIN) is a rare entity in the pediatric age. It is de fined by the infiltration of the renal parenchyma by mononuclear and/or polynuclear cells with se condary involvement of the tubules, without glomerular injury. It can be triggered by infections or immunological diseases, drugs like NSAIDs or be of idiopathic origin. OBJECTIVE: To raise awareness among pediatricians about the prescription of NSAIDs, especially to patients of less than a year old, since they can provoke renal damage...

PURPOSE: Acute lung injury (ALI) is a fatal syndrome in critically ill patients. It is characterized by lung edema and inflammation. Numerous pro-inflammatory mediators are released into alveoli. Among them, interleukin-1beta (IL-1β) causes an increase in solute permeability across the alveolar-capillary barrier leading to edema. It activates key effector cells (alveolar epithelial and endothelial cells) releasing inflammatory chemokines and cytokines. The purpose of the study was to demonstrate that nebulized liposomes inhibit ALI in vivo...

BACKGROUND: Although a combination therapy, comprising 2-year high-dose oral prednisolone (PSL), is effective for treating childhood immunoglobulin A nephropathy (IgAN), severe adverse effects and residual proteinuria occur in some patients after the therapy. METHODS: To clarify the efficacy of intravenous pulse methylprednisolone (IVMP; 15-20 mg/kg; maximum 600 mg/day; for 3 consecutive days/week for 3 weeks) followed by short-term reduced-dose PSL (initially 1 mg/kg; maximum 30 mg on alternate days; tapered off within approximately 12 months) and tonsillectomy as an initial treatment, we retrospectively reviewed the clinical courses of 54 consecutive children with IgAN (32 boys; mean age at onset, 12...

Malignant atrophic papulosis (MAP) is a rare type of obliterating vasculopathy that can present as pure cutaneous lesions or a systemic entity affecting multiple organs. Systemic disease, such as gastrointestinal or central nervous system involvement, may predispose the patients to poorer or even fatal outcomes. We present a 30-year-old female patient with systemic manifestation of MAP 10 days after delivery of a full-term pregnancy who subsequently developed motor aphasia and intestinal perforation. The patient was administrated empirical treatment with an antiplatelet, anticoagulant, methylprednisolone sodium succinate and alprostadil...

We present a case of an 82-year-old man with new-onset neuromyelitis optica (NMO) spectrum disorder, the treatment of which was complicated by a severe pre-existing prednisone allergy. His age caused much initial doubt about his diagnosis, and his corticosteroid allergy altered our management as we attempted to minimize risk to the patient. Our patient was a healthy 82-year-old, right-handed man who presented with sensory loss of the bilateral lower extremities and progressive, painless vision loss. MRI showed bilateral pre-chiasmatic optic nerve and optic chiasm enhancement, along with enhancement within the thoracic spinal cord from T3 to T7...

Glucocorticoids (GCs) are the most common cause of atraumatic osteonecrosis of the femoral head (ONFH) because their effect compromises the osteogenic capability of bone marrow‑derived mesenchymal stem cells (BMSCs). Valproic acid (VPA) is a widely used anti‑epileptic and anti‑convulsant drug. Previous studies have reported that VPA promotes osteogenic differentiation of MSCs in vitro and osteogenesis in vivo as a histone deacetylase (HDAC) inhibitor. The purpose of the present study was to investigate the efficacy of VPA as a precautionary treatment of ONFH after GC treatment in rats...

Idiopathic hypertrophic pachymeningitis (HP) is a rare clinical entity characterized by thickening of the dura mater without obvious underlying disease. High-dose steroid therapy is considered to be the first line for idiopathic HP, but half of patients show resistance for steroid therapy and suffer progressive clinical course. We describe low-dose methotrexate (MTX) administration for recurrent and steroid-resistant idiopathic HP resulting in noticeable improvement without severe adverse effects. A 51-year-old Japanese woman with dermatomyositis first presented with right retro-orbital pain caused by dural thickening in the sella and upper clivus involving the right trigeminal nerve, which was diagnosed as idiopathic HP by transsphenoidal biopsy...

Recent advances in immunosuppressive regimens have decreased acute cellular rejection (ACR) rates and improved intestinal transplant (ITx) recipient survival. We investigated the role of myeloid-derived suppressor cells (MDSCs) in ITx. We identified MDSCs as CD33+ CD11b+ lineage(CD3/CD56/CD19)- HLA-DR-/low cells with 3 subsets, CD14- CD15- (e-MDSC), CD14+ CD15- (M-MDSC), and CD14- CD15+ (PMN-MDSC), in peripheral blood mononuclear cells (PBMCs) and mononuclear cells in the grafted intestinal mucosa. Total MDSC numbers increased in PBMCs following ITx; among MDSC subsets, M-MDSC numbers were maintained at high level after 2 months following ITx...

Importance: Intravenous (IV) administration of corticosteroids is the standard of care in the treatment of acute optic neuritis. However, it is uncertain whether a bioequivalent dose of corticosteroid administered orally, which may be more cost-efficient and convenient for patients, is as effective as IV administration in the treatment of acute optic neuritis. Objective: To determine whether recovery of vision following treatment of acute optic neuritis with a high-dose IV corticosteroid is superior to that with a bioequivalent dose of an oral corticosteroid...

Drug-induced liver injury is the fourth most common cause of liver disease in industrialised countries. Methylprednisolone is often considered to be a treatment with a low hepatotoxicity. We report a case of methylprednisolone-induced liver injury in a 35-year-old woman. She was admitted to our department for acute liver injury 2 months after a treatment with high dose of methylprednisolone (1 g/day) for a multiple sclerosis relapse. No other cause of liver injury could be found (screening for hepatotropic viruses, autoimmune antibodies, ceruloplasmin, abdominal ultrasonography and liver biopsy)...

BACKGROUND: Visceral disseminated varicella zoster viral (VZV) infection is a rare but severe complication with a high mortality rate in immunosuppressed individuals, and an increased susceptibility to VZV has been reported in kidney transplant recipients who are treated with mycophenolate mofetil (MMF). In Japan, MMF is currently approved for patients with lupus nephritis (LN) and data to indicate its optimal dosage are still insufficient. CASE PRESENTATION: A 46-year-old Japanese woman with rheumatoid arthritis was diagnosed as having systemic lupus erythematosus (SLE) and LN class III (A/C)...
