Subjective feeling of tiredness characterized by a lack of energy and motivation that persists for six months or longer.

Warts, benign growths on the skin or mucous membranes that cause cosmetic problems as well as pain and discomfort. Warts most often occur on the hands, feet, and genital areas.

Multiple verrucous lesions on the skin of the palm. These lesions are raised, have a thickened and rough surface, and may display prominent black dots (thrombosed capillaries). Palmar warts are caused by human papillomavirus (HPV).

Ulcerative colitis is a chronic disorder that affects the digestive system. This condition is characterized by abnormal inflammation of the inner surface (epithelium) of the rectum and colon. The rectum and colon make up most of the length of the large intestine. The inflammation usually causes open sores (ulcers) to develop in the large intestine. Ulcerative colitis usually appears between the age of 15 and 30, although it can develop at any age. The inflammation tends to flare up multiple times throughout a person's life, which causes recurring signs and symptoms.\n\nThe most common symptoms of ulcerative colitis are cramping abdominal pain and frequent diarrhea, often with blood, pus, or mucus in the stool. Other signs and symptoms include nausea, loss of appetite, bowel urgency, fatigue, and fevers. Chronic bleeding from the inflamed and ulcerated intestinal tissue can cause a shortage of red blood cells (anemia) in some affected individuals. People with this disorder have difficulty absorbing enough fluids and nutrients from their diet and often experience weight loss. Affected children usually grow more slowly than normal. Less commonly, ulcerative colitis causes problems with the skin, joints, eyes, kidneys, or liver, which are most likely due to abnormal inflammation.\n\nToxic megacolon is a rare complication of ulcerative colitis that can be life-threatening. Toxic megacolon involves a widening (dilation) of the colon and an overwhelming inflammatory response. Ulcerative colitis also increases the risk of developing colon cancer, especially in people whose entire colon is inflamed and in those who have had ulcerative colitis for 8 years or more.\n\nUlcerative colitis is one common form of inflammatory bowel disease (IBD). Another type of IBD, Crohn's disease, also causes chronic inflammation of the intestines. Unlike ulcerative colitis, which affects only the inner surface of the large intestine, Crohn's disease can cause inflammation in any part of the digestive system, and the inflammation extends deeper into the intestinal tissue.

A disorder of esophageal motility characterized by the inability of the lower esophageal sphincter to relax during swallowing and by inadequate or lacking peristalsis in the lower half of the body of the esophagus.

A recurrent form of sinusitis.

Celiac disease is a systemic autoimmune disease that can be associated with gastrointestinal findings (diarrhea, malabsorption, abdominal pain and distension, bloating, vomiting, and weight loss) and/or highly variable non-gastrointestinal findings (dermatitis herpetiformis, chronic fatigue, joint pain/inflammation, iron deficiency anemia, migraines, depression, attention-deficit disorder, epilepsy, osteoporosis/osteopenia, infertility and/or recurrent fetal loss, vitamin deficiencies, short stature, failure to thrive, delayed puberty, dental enamel defects, and autoimmune disorders). Classic celiac disease, characterized by mild to severe gastrointestinal symptoms, is less common than non-classic celiac disease, characterized by absence of gastrointestinal symptoms.

Failure of the immune system to protect the body adequately from infection, due to the absence or insufficiency of some component process or substance.

An abnormally decreased level of immunoglobulin M (IgM) in blood.

An infection of a hair follicle that extends subcutaneously, forming an abscess.

An abnormal decrease from the normal count of B cells.

Undetectable serum immunoglobulin A level at a value < 5 mg/dL (0.05 g/L).

An abnormally decreased level of immunoglobulin in blood.

A reduction beneath the normal level of total immunoglobulin G (IgG) in the blood.

A decreased proportion of circulating CD4-positive helper T cells relative to total T cell count.

Multiple verrucous lesions on the skin of the sole of the foot. These lesions are raised, have a thickened and rough surface, and may display prominent black dots (thrombosed capillaries). Palmar warts are caused by caused by human papillomavirus (HPV).

Inflammation of retinal blood vessels as manifested by perivascular sheathing or cuffing, vascular leakage and/or occlusion.
