GUNTHER DISEASE

Gunther disease is a metabolic disease that affects the production of hemoglobin, the iron-containing component that bonds oxygen into red blood cells.

It is a hereditary disease caused by a mutation in the genes producing uroporphyrinogen III synthase on chromosome 10. Further, Gunther disease is an autosomal recessive, which implies both parents have acquired a defective gene. The majority of people who have a single faulty gene do not show any indications or symptoms of the disease.

Field fever is an animal-to-human bacterial illness. It is carried via urine, particularly by dogs, rats, and agricultural animals. Even if they develop no symptoms, they are nonetheless carriers.

A bacteria called Leptospira interrogans causes field fever. Most animals carry the bacterium, which dwells in their kidneys. Through their pee, it goes up in the water and soil. In this case, the germ may enter your body via breaches in your skin, such as scrapes, open wounds, or dry patches, if you’re near in the soil or water where an infected animal has urinated.

Field fever, like the flu, is often unpleasant but not fatal. It typically lasts a week. However, when you have a serious type of field fever approximately 12% of the time you will get well, but then get ill again. This is known as Weil’s illness, and it may lead to much more severe complications such as chest discomfort and swelling limbs and legs. It often necessitates hospitalization.

SYMPTOMS

Gunther disease symptoms may appear at any age and can vary from minor to severe. These symptoms include:

  • Anemia
  • Reddish urine
  • Scarring, erosions, blistering, and swelling of skin
  • Stained teeth
  • Inflamed eyes
  • Deformities of facial structures
  • Rupture and scarring cornea
  • Fragile bones and enlarged spleen

If you see any of these symptoms, see a doctor right once to avoid severe complications.

DIAGNOSIS

There are four stages of making a diagnosis of Gunther disease. First, a detailed history (including family history) and health assessment with specific care given to sun-exposed skin. 

Furthermore, porphyrins and precursors must be measured biochemically in urine, feces, and blood. However, only specialized laboratories can assist with assessing the efficiency of particular enzymes in the heme production pathway, as well as DNA and mutational studies. 

Also,the presence of high amounts of uroporphyrin 1 in urine, feces, and circulating red blood cells confirms the diagnosis of Gunther disease. The following are the findings:

  • Coproporphyrin I and raised urinary uroporphyrin I 
  • Stable fluorescence of circulating RBC on vulnerability to UVA.
  • Raised faecal coproporphyrin I

TREATMENT

There are many methods to cure Gunther’s illnesses, but one of the most important things that a person with this condition can do is restrict or prevent sun exposure. Some skin care products, like tropical sunscreens, have unfavorable side effects. However sunscreens including zinc oxide and titanium dioxide have been proven to guarantee safety owing to their light-reflective properties.

Other therapies that have been suggested include:

  • High dosage of beta carotene, to acquire light energy.
  • Low-dosage of hydroxychloroquine to boost porphyrin excretion
  • Afamelanotide
  • Blood transfusion

Another possible treatment is bone marrow transplant. Although long-term outcomes are not yet known, bone marrow transplantation has been effective in a few instances. This therapy is currently being tested.
