Alpha-chain disease in a non-Mediterranean climate. A case report
South African Medical Journal = Suid-Afrikaanse Tydskrif Vir Geneeskunde
|December 13, 1975
Summary
This case study details a patient with alpha-chain disease, highlighting clinical, biochemical, and immunological findings. Chemotherapy led to symptomatic improvement but not full recovery, indicating complex disease management.
Area of Science:
- Immunology
- Gastroenterology
- Hematology
Background:
- Alpha-chain disease is a rare lymphoproliferative disorder characterized by the production of abnormal immunoglobulin heavy chains.
- Understanding its clinical, biochemical, immunological, and histopathological features is crucial for diagnosis and management.
Observation:
- A 20-year-old male presented with severe steatorrhoea, malabsorption, abdominal pain, and progressive deterioration.
- Electrophoresis revealed an abnormal IgA band in serum and urine, identified as free alpha-chain.
- Jejunal biopsy showed characteristic features, with bone marrow involvement and abnormal lymphoid cells observed.
Findings:
- The patient exhibited a heterogeneous abnormal band with IgA specificity, confirmed as free alpha-chain in various bodily fluids.
- Histopathology revealed distinctive appearances of alpha-chain disease in the jejunal mucosa and bone marrow.
- Abnormal lymphoid cells and an increased B lymphocyte population were noted in circulation.
Implications:
- This case contributes to the understanding of alpha-chain disease, particularly in South Africa.
- Partial remission was achieved with chemotherapy, showing symptomatic and protein normalization but limited objective response.
- Further research is needed to optimize treatment strategies for alpha-chain disease.

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

01:24Nephrotic Syndrome I : Introduction
708
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

01:30Atherosclerosis I: Introduction
1.4K
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

9.3K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
