A79.82
Anaplasmosis [A. phagocytophilum]
Clinical Classification Guidelines
Inclusion Terms
- Transfusion transmitted A. phagocytophilum
Medical Intelligence & Overview
Anaplasmosis is a tick-borne infectious disease caused by the bacteria Anaplasma phagocytophilum. It primarily affects individuals exposed to tick habitats and can sometimes be transmitted through blood transfusions. Recognized under ICD-10 code A79.82, anaplasmosis can lead to serious health issues if not diagnosed and treated promptly. This guide aims to provide a clear understanding of the disease's causes, symptoms, diagnosis, and treatment options in an accessible manner.
Causes & Symptoms
Clinical Causes: Tick bites from infected Ixodes ticks, which carry the bacteria Anaplasma phagocytophilum. Blood transfusions involving blood contaminated with A. phagocytophilum, which can lead to transfusion-transmitted anaplasmosis. Rarely, by contact with contaminated blood or tissues from an infected individual.
Key Symptoms: Fever and chills Headache Muscle aches and joint pain Fatigue and weakness Nausea and vomiting Difficulty breathing in severe cases Confusion or changes in mental state Sometimes, rash or skin changes (less common)
Diagnostic & Treatment
Diagnosis Path: Diagnosis of anaplasmosis involves a combination of medical history, physical examination, and laboratory tests. Blood tests such as blood smears under a microscope can reveal infected cells. Polymerase chain reaction (PCR) tests are highly sensitive and can detect bacterial DNA. Serological tests may also be used to identify antibodies to Anaplasma phagocytophilum, indicating recent or past infection. Prompt diagnosis is vital for effective treatment and recovery.
Treatment Protocols: Treatment typically includes antibiotics such as doxycycline, which are effective against the bacteria. Most patients recover fully with appropriate therapy. Supportive care, including rest and hydration, can help alleviate symptoms. In severe cases, hospitalization may be necessary to manage complications. Preventive measures include avoiding tick habitats, using protective clothing, applying tick repellents, and, in transfusion cases, screening blood donors for A. phagocytophilum.
