Summary
Late onset systemic lupus erythematosus (SLE) presents after age 50, often mimicking aging symptoms. Early recognition is crucial for accurate diagnosis and management of this autoimmune condition.
Area of Science:
- Rheumatology
- Immunology
- Geriatric Medicine
Background:
- Systemic lupus erythematosus (SLE) is a complex autoimmune disorder typically affecting individuals aged 15-40.
- Late onset SLE (LO-SLE) is defined as onset after age 50, representing 2-20% of all SLE cases.
- LO-SLE diagnosis can be challenging due to overlapping symptoms with common aging-related conditions.
Observation:
- The case highlights a patient initially suspected of having polymyalgia rheumatica (PMR).
- Elderly patients presenting with arthralgia, myalgia, fatigue, and sicca symptoms may have LO-SLE.
- Symptoms can be misattributed to normal aging or other degenerative processes.
Findings:
- LO-SLE requires specific clinical consideration in older adults.
- Differentiating LO-SLE from PMR and other conditions is essential for appropriate treatment.
- This case underscores the importance of a high index of suspicion for autoimmune diseases in the elderly.
Implications:
- Timely diagnosis of LO-SLE can prevent long-term organ damage.
- Increased awareness among clinicians can improve patient outcomes for LO-SLE.
- Further research into LO-SLE's unique presentation and management is warranted.

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
