The term B symptoms denotes a triad of the following symptoms
- Unexplained fever (> 38 ° C)
- massive night sweats (wet hair, soaked sleeping clothes)
- Unintentional weight loss of more than ten percent of body weight within six months
The B symptoms can occur in inflammatory diseases such as tuberculosis , actinomycosis , HIV infection, or invasive intestinal diseases caused by amoebas, but also in malignant processes (e.g. Hodgkin lymphoma ) and are considered to be an unfavorable prognostic sign. The most important means of recording B symptoms is a precise history of the patient.
For concept formation
The letter “B” in the term “B symptoms” is explained by the two additions “A” and (as here) “B” of the Ann Arbor classification for malignant lymphomas . If the above-mentioned symptoms are present, one speaks of a "B-symptomatology", if they are missing, of an "A-symptomatology". In German, the term "B-Symptomatik" can also stand for "accompanying symptoms".
