Leukocytosis autoimmune

Juvenile idiopathic arthritis (JIA) is a heterogeneous group of arthritis of autoimmune aetiology. Systemic-onset juvenile idiopathic arthritis (soJIA) presents with fever, transient erythematous rash, hepatomegaly, splenomegaly, lymphadenopathy, and serositis. SoJIA presents multiple complications, and the most severe is the macrophage activation syndrome (MAS); the timely treatment of MAS must be established early and aggressively to avoid a fatal outcome. Therapeutic plasma exchange has anecdotally been used in refractory cases...

BACKGROUND: Myelin oligodendrocyte glycoprotein (MOG) antibodies mediate inflammatory demyelinating diseases of the central nervous system. This study aimed to understand the clinical characteristics of MOG antibody-associated aseptic meningitis (MOGAM). METHODS: Here, we report the cases of two children with MOGAM. A systematic literature review was conducted and included patients who had MOGAM only, without neurological parenchymal lesions. The clinical characteristics that may have affected the outcome were statistically analyzed...

BACKGROUND: This case reveals a novel presentation of drug rash with eosinophilia and systemic symptoms syndrome that mimics a lymphoproliferative disorder. The heterogeneous clinical presentation of drug rash with eosinophilia and systemic symptoms syndrome gives rise to a broad differential diagnosis that includes a multitude of infectious, inflammatory, and autoimmune conditions. This patient was diagnosed with drug rash with eosinophilia and systemic symptoms syndrome 4 weeks after starting sulfasalazine and 5 weeks after starting hydroxychloroquine for rheumatoid arthritis...

BACKGROUND: Bickerstaff brainstem encephalitis (BBE) is a rare demyelinating disease of the central nervous system (CNS) that is caused by a direct viral infection or secondary autoimmune responses. BBE secondary to Herpes zoster has rarely been reported. CASE PRESENTATION: A 68-year-old man developed a painful vesicular rash and drooping eyelid on the left side of his face for 20 days. Physical examination revealed left-sided blepharoptosis and crusted erythema on the left front side of his face, left upper eyelid, and left nasal tip...

BACKGROUND: Tuberculosis is a bacterial infection involving multiple organs and systems. Its hematological presentation mainly includes anemia and leukocytosis. Evans syndrome is a rare autoimmune disease characterized by autoimmune hemolytic anemia, immune thrombocytopenia, and neutropenia, with positive results for the direct Coombs test and platelet antibodies. The cooccurrence of tuberculosis and Evans syndrome is rarely reported. CASE PRESENTATION: A 69-year-old female presented with a fever and shortness of breath...

BACKGROUND: Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is the most frequent autoimmune paraneoplastic encephalitis, and is primarily associated with ovarian teratomas. Here, we report the first case of a patient diagnosed with chronic myelogenous leukemia (CML) during the recovery phase of anti-NMDAR encephalitis. CASE PRESENTATION: The patient was admitted with fever, headache, and seizures. Brain MRI revealed a cerebrospinal fluid (CSF)-containing arachnoid cyst in the left temporal lobe with no other abnormal signals...

We report a rare case of sterile neutrophilic dermatosis (Sweet's syndrome) accompanied by systemic inflammatory response syndrome. A 5-year-old, neutered male Maltese dog presented with extensive crusts on the whole-body surface and multifocal erosions and plaques on the four limbs. The lesions had been present for two months and did not respond to antibiotics before the presentation. In addition, the dog was lethargic, anorexic, and febrile, with joint swelling. A clinicopathologic analysis revealed neutrophilic leukocytosis with left shift and increased C-reactive protein level...

Hypocalcemia can manifest as a variety of presentations, ranging from neuromuscular irritability to seizures, and psychiatric manifestations such as emotional instability, anxiety, and depression. Here, we present a unique case of hypocalcemia-induced acute psychosis. A 24-year-old woman presented to the emergency department (ED) with confusion and agitation for four to five days. The patient was noted by the family to have decreased oral intake and sleep. Auditory and visual hallucinations prompted the family to bring the patient to the ED...

Invasive aspergillosis is a rare opportunistic infection mainly occurring in patients with a well-established risk such as neutropenia or conditions that lead to chronically impaired cellular immune responses. Systemic corticosteroids are a well-known risk factor for fungal infections. Recently, reports of invasive aspergillosis in patients treated with monoclonal biologic agents, such as tumor necrosis factor-alpha inhibitors, have been increasing. We present the case of a 47-year-old female patient with seronegative spondyloarthropathy treated with infliximab and corticosteroids...

BACKGROUND Acute fatty liver of pregnancy (AFLP) is a rare obstetric emergency resulting from microvesicular infiltration of the liver by fat, leading to liver failure. It usually presents at 36 weeks of gestation, and risk factors include twin pregnancy and low BMI. The presentation of AFLP is nonspecific, requiring a high index of suspicion. The Swansea Criteria is used to aid diagnosis. CASE REPORT Case 1: A 23-year-old woman, G1P0 at 39 weeks of gestation, presented to the hospital with a 1-week history of fever, nausea, vomiting, and diarrhea...

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease involving the neuromuscular junction. Myasthenic crisis (MC), which is characterized by respiratory failure and the requirement of mechanical ventilation in patients with MG, is still a medical emergency despite the decrease in mortality with the advances in acute management. Hemogram is a cost-effective test for evaluating hematological complications and systemic inflammation, and hemogram data have been used to predict various clinical outcomes of several diseases...

BACKGROUND AND OBJECTIVE: To present 6 new cases with Homer-3 antibodies that expand their clinical spectra and to evaluate the effect of immunotherapy. METHODS: Patients with suspected autoimmune cerebellar disorder were tested for rare autoimmune cerebellar ataxia (ACA) antibodies (anti-Tr(DNER)/Zic4/ITPR1/Homer-3/NCDN/PKCγ/PCA-2/AP3B2/mGluR1/ATP1A3 antibodies) using both cell-based and tissue-based assays. Patients with positive serum or CSF results who were diagnosed with ACA were registered and followed up...

A 24-year-old previously healthy woman was brought to the hospital for acute altered mental status. One week prior to presentation, she had developed a sore throat, nausea, and vomiting. At that time, SARS-CoV-2 polymerase chain reaction and rapid streptococcal pharyngitis test results were both negative. On the day prior to presentation, the patient had developed an erythematous painful rash on her left arm. The following day she was noted to be agitated, combative, and having trouble communicating, prompting ED evaluation...

Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive malignancy with a presentation like either autoimmune diseases, drug reactions, or infections. We hereby present a unique case of AITL. A 61-year-old Caucasian male with a past medical history of chronic obstructive pulmonary disease (COPD) presented to the emergency department with a rash over his bilateral knees, shortness of breath, and productive cough of few days. He was managed for suspected COPD exacerbation associated with community-acquired pneumonia...

Rheumatoid arthritis (RA) is an autoimmune disease characterized by inflammation in the joints. Although methotrexate (MX) is the first-line treatment, side effects are common. This study aimed to investigate the effects of quercetin (QT) and/or MX on inflammation and systemic toxicity in a rat model of RA. Male Wistar rats were divided into control (C), RA, QT, MX, and QT + MX groups (n=6). The RA induction consisted of three intra-articular injections of methylated bovine serum albumin (1×/week) in the temporomandibular joint (TMJ)...

Immunoglobulin G4-related disease (IgG4-RD) is a heterogeneous autoimmune fibrosing disorder that presents common pathologic features but with unclear etiology. We report a rare case of IgG4-RD accompanied by primary myelofibrosis that eventually transformed into acute myeloid leukemia. A 50-year-old woman suffered from progressive lacrimal and parotid gland enlargement, diaphoresis, and rapid weight loss. Important clinical findings included remarkable leukocytosis, hyperglobulinemia, and splenomegaly. IgG4-RD was confirmed by salivary gland biopsy...

BACKGROUND: Adult-onset Still's Disease (AOSD) is a systemic inflammatory condition, mainly characterized by high spiking fevers, leukocytosis, skin rash, arthralgia and myalgia. Liver involvement is a frequent feature, usually presenting with hepatomegaly and mild liver enzymes abnormalities, which usually normalize after treatment with anti-inflammatory or immunomodulatory drugs given for AOSD. Although uncommon, the onset of severe acute hepatitis and even of life-threatening liver failure is possible and requires a prompt diagnosis and an aggressive therapy and, in some cases, an emergency liver transplantation...

Schnitzler syndrome (SS) is a rare disease of unknown etiology. Literature suggests that only around 300 well-diagnosed cases have only been reported worldwide and rarely from India. This syndrome has a slight male predominance with a mean age of onset of around 50 years. It is considered an autoinflammatory disease with presentation mimicking adult-onset Still's disease and systemic lupus erythematosus, and its presentation most commonly includes recurrent fever, urticarial rash, arthralgia, and bone pains...

Peripheral lymphadenopathy (LAP) is an important and common abnormal finding of the physical exam in general medical practice. We aimed to reveal the LAP etiology and demographic, clinical and laboratory variables that may be useful in the differential evaluation of LAP. This multicenter, nested case-control study including 1401 patients between 2014 and 2019 was conducted in 19 tertiary teaching and research hospitals from different regions in Turkey. The ratio of infectious, malign and autoimmune/inflammatory diseases was 31...

Kawasaki disease is an acute multisystem vasculitis characterized by involvement of medium-sized vessels that mostly affects children under the age of 5 years. The presentation is typically preceded by five or more days of fever with additional clinical findings including rash, peripheral edema, mucositis, conjunctival changes, and unilateral cervical lymphadenopathy. The most feared complication of Kawasaki disease is development of coronary artery aneurysms. Common laboratory abnormalities include normocytic anemia, thrombocytosis, leukocytosis, and elevated inflammatory markers...
