RESUMEN
Calcium pyrophosphate deposition disease is categorized into radiographic chondrocalcinosis, acute calcium pyrophosphate arthritis, chronic calcium pyrophosphate arthritis, and osteoarthritis with calcium pyrophosphate deposition. These entities collectively are characterized by the deposition of calcium into joints, which then may cause localized and systemic inflammation, resulting in pain and swelling in the affected joints. Patients with the ANKH gene are more susceptible to the development of CPP arthritis as are those with primary hyperparathyroidism, hypomagnesemia, and hemochromatosis. Radiographic chondrocalcinosis is asymptomatic. Acute calcium pyrophosphate arthritis results in self-limited periods of joint pain and swelling in the affected joint. Along with localized inflammation, there may also be systemic inflammation characterized by fever and elevated inflammatory markers. Chronic calcium pyrophosphate arthritis results in periods of quiescence interrupted by flares that are identical to acute periods of disease. Osteoarthritis associated calcium pyrophosphate arthritis presents with chronic pain well described in osteoarthritis with periods of acute flares. In 2023, a joint effort by the American College of Rheumatology and the European League Against Rheumatism developed guidelines meant to aid in the recognition of calcium pyrophosphate deposition diseases. The diagnosis is made if there is proof of either crowned dens syndrome or synovial fluid analysis demonstrating calcium pyrophosphate crystals or when more than 56 points are summed utilizing the criteria described in the guidelines. Radiographic chondrocalcinosis requires no therapy. Acute calcium pyrophosphate arthritis is treated with the goal of aborting the flare. Treatment options include nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, oral corticosteroids, parenteral corticosteroids, intraarticular corticosteroids, IL-1 inhibitors, or parenteral adrenocorticotropic hormone (ACTH). The goal in treatment for chronic calcium pyrophosphate arthritis is the suppression of acute flares. The drugs used for acute flare treatment may be given as maintenance therapy with the additional options of methotrexate and hydroxychloroquine.
RESUMEN
A novel coronavirus was identified at the end of 2019, causing a pneumonia epidemic in China, which later rapidly spread to cause a global pandemic. However, most people who contracted the COVID-19 had mild to moderate symptoms. A fair percentage developed ARDS, Septic shock, and multi-organ failure. Given the necessity of immunization in combating this disease, COVID-19 vaccines were widely deployed, giving rise to multiple reported cases of post-vaccination autoimmune flareups and new onset of autoimmune phenomena. We present a case of an 81-year-old female who was diagnosed with erosive arthritis post COVID-19 vaccination.
RESUMEN
Encephalopathy with autoimmune thyroid disease (EAATD) is mostly associated with Hashimoto's thyroiditis and has been uncommonly reported with Grave's disease. This case is aimed to report the association of EAATD with thyroid peroxidase (TPO) and thyroid-stimulating immunoglobulin (TSI) antibodies in Grave's disease. We report a 55-year old male who presented with thyrotoxicosis and cerebellar ataxia and was diagnosed with Grave's disease based on clinical and biochemical findings. The patient was managed with anti-thyroid medications with resolution of both thyrotoxicosis and cerebellar symptoms proving the hypothesis that patient's encephalopathy was autoimmune and related to his thyroid disease. High index of suspicion should be maintained for EAATD in patients presenting with neurological deficits with associated clinical and biochemical evidence of autoimmune thyroid disease.
RESUMEN
A 23-year-old woman with history of systemic lupus erythematous presented with dizziness and headache and was admitted for the stroke workup. During her stay, she had sudden painless loss of vision in her right eye consistent with central retinal artery occlusion (CRAO). Ocular massage and paracentesis were attempted without success to resume the flow. She was started on oral high-dose steroids (1 mg/kg) for lupus flare and therapeutic anticoagulation for antiphospholipid syndrome (positive for anticardiolipin and beta-2 microglobulin antibodies). On day 4, she started having painful bluish discoloration of her left index finger and right fifth toe, and on day 5 she had acute onset of left blurry vision with findings consistent with CRAO. She fulfilled the criteria of catastrophic antiphospholipid syndrome and was started on intravenous pulse steroids, plasmapheresis and higher international normalised ratio goal of 3-3.5 with improvement in her left eye vision from 20/200 to 20/20 on near card test by the end of treatment.
