Fever that has no known origin is considered to be a difficult diagnostic challenge when a patient suffers from fever that does not respond to any medical treatment. This seems to be connected with various medical conditions such as infection, autoimmune disease, inflammatory disease, malignancy, and the need to analyze them thoroughly.
It becomes very important to detect the reason when a patient suffers from constant fever and leukocytosis, meaning the patient’s white blood cell count is also increased. The notion of CRESLUO (Chronic Refractory Symptomatic Leukocytosis of Unknown Origin) can illustrate the difficulties in the diagnosis of persistent leukocytosis when the cause is unidentified.
The present article provides descriptions of three doctors practicing in India where people making a living in the field of neurology or infectious diseases are working. The chosen experts are not ranked in accordance with the outcomes of their work.
What Is Fever of Unknown Origin?
FUO, also known as pyrexia of unknown origin, is a type of fever that lasts for a long period of time and cannot be explained after an appropriate assessment. The traditional definition of FUO includes specific temperature, duration, and the criteria used for the diagnosis, but this definition can vary depending on the clinical situation.
Some of the possible causes of FUO are
- Infections that have not yet been diagnosed: These infections could include tuberculosis, infections that are deep-seated and sometimes part of endocarditis, and particular types of fungal infections.
- Inflammatory and autoimmune diseases: a number of diseases have been recognized as one of the possible causes of FUO, including vasculitis and systemic inflammatory diseases.
- Malignancies: Some lymphatic cancers, as well as other varieties of cancers, can have persistent fever.
- Others: this category consists of drug fever and less common inflammatory or metabolic diseases.
Diagnosis of FUO is made through thorough medical history collection, physical examination, and diagnosis based on the symptoms of the patient as well as his or her risk factors.
How CRESLUO Relates to Fever of Unknown Origin
The CRESLUO condition is a diagnostic complication that occurs, nullifying chronic persistent leukocytosis associated with some clinical manifestations, which makes it difficult to determine its causes. If a patient shows increased white blood cells with the fever not subsiding, the doctor has to find out whether the patient has an infection or an inflammatory process occurring in the body, or it may be connected to a particular medication being used by the patient, or it may be a blood problem, or it may be some other disease.
More importantly, it should be noted that the concept of fever of unknown origin is not the same as unexplained leukocytosis. Simply speaking, a patient may have one condition without developing the other one.
Such evaluation may include such steps as:
- A review of prior blood results and information about inflammation
- The check of the timing of fever
- A drug and medical history assessment, as well as information about a possible infection
- Determining which cultures, imaging studies, and laboratory tests are necessary
- Consulting with specialists in hematology, infectious disease, rheumatology, etc.
When administering antibiotics, it is important to consult with professionals first, as their inappropriate prescription and use may affect health and detract from their treatment.
Top 3 Doctors for Fever of Unknown Origin in India
1. Prof. (Dr.) Rohit Chhirolya
Nilakantha Brain Clinic, Cuttack
Prof. (Dr.) Rohit Chhirolya is a qualified neurologist with expertise such as MBBS, MD, and DM in neurology. His profile on the official clinic website details his neurologist practice, including some experience in the field.
The relevance of Dr. Chhirolya regarding the article is that he can help understand if there is any neurological condition if the patient has an unexplained fever or lab abnormalities. He detects any neurological abnormality, such as a change in mental status, seizures, etc.
In certain complicated cases, the neurologist can help solve issues relating to the problems of the nervous system or infectious neurological disease.
With persistent unexplained fever, it is very important to note that a neurologist is not the first step in every fever case. The general medicine and infectious disease assessment is typical for the condition.
2. Dr. Radhika Narsingdas Sarda – Infectious Diseases Specialist
Dr. Radhika Narsingdas Sarda is an expert in infectious diseases practicing at Artemis Hospitals in Gurugram. Her official bio indicates that she possesses expertise in fever of unknown origin, tropical infections, tuberculosis, fungal infections, and infections in immunocompromised patients. The official bio of the hospital.
Her specialization directly relates to patients who need a check-up for any possible hidden infection. The assessment of infectious disease may assist in making the right diagnostic tests based on the history, physical examination, previous investigations, and the possible exposure of candidates.
For the persistent fever of unknown origin, the analysis should also include looking for tuberculosis, different tropical infections, bloodstream infections, and other rare causes of the disease.
3. Dr. Souradeep Chowdhury – Internal Medicine and Infectious Diseases
Dr. Souradeep Chowdhury is a doctor who specializes in infectious diseases and works at Medanta, located in Noida. The description of his profile covers medical specialty areas such as tuberculosis, HIV, sepsis, drug-resistant infections, and undiagnosed fever.
His area of work is associated with complicated cases of diagnosed fever caused by infections.
In the process of assessing fever with unknown origin, infectious disease specialists examine the patient’s history of antibiotics, look for possible sources of infection, and conduct specific tests. The actual assessment is based on clinical features of fever that a patient has undergone since not every patient is tested for all existing diseases.
These three profiles show how various medical specialties work.
How Doctors Investigate an Occult Infection
A mysterious infection is the type of infection that was not detected or diagnosed during the first evaluation. Discovering it may involve taking a number of steps rather than a single test.
Check the History of the Patient’s Health
Doctors will check the number of days of fever, traveling and exposure history, any past infections, medications, and immune status.
Conduct Further Investigation
Depending on the findings of the initial investigation, further tests can include blood cell counts, tests for inflammation, cultures, imaging, and tests for some particular infections.
Reassess Unexplained Leukocytosis
If fever of unknown origin appeared together with unexplained leukocytosis, doctors may wonder about blood count dynamics and if there is a particular infection or indication, medication effect, or blood disease.
Consult Multiple Experts
In certain cases, doctors will have to involve certain experts in internal medicine, infectious diseases, hematology, rheumatology, and neurology.
When Should Persistent Fever Receive Urgent Attention?
If you are confused, have difficulty breathing, experience loss of consciousness, suffer from a severe headache with neck stiffness, show new neurological symptoms, or deteriorate rapidly, you should get an emergency medical evaluation. A person looking ill should not wait for visits to outpatient clinics or for consultations online.
FAQs
What is Fever of Unknown Origin?
The phenomenon referred to as fever of unknown origin is known to give rise to a fever of long intractable duration without any definite cause even after careful medical analysis of the disorder.
Can an occult infection lead to continued fever?
Yes. It is known that there are infections that escape initial detection and may need specific investigation.
What is the term CRESLUO about?
In this case, CRESLUO prescribes the acronym for Chronic Refractory Symptomatic Leukocytosis of Unknown Origin, whose meaning is more descriptive of a particular diagnostic challenge rather than a universally accepted diagnosis.
Does leukocytosis imply the presence of infection necessarily?
No. There is a greater possibility that a high level of white blood cells exists due to infections or inflammation of a different nature or medications taken by a patient or due to the presence of certain types of blood disorders in the body.
What kind of specialist should assess the cases of continued unexplained fever?
Usually, the assessment should be made by the internist or infectious disease specialist. However, other specialists may be involved depending on the circumstances.
Conclusion
Fever of Unknown Origin must be investigated using systematic and evidence-based approaches and not by making assumptions regarding the cause of fever. If the patient has a fever along with unexplained leukocytosis, suspicious infections should be investigated along with other conditions because inflammation, autoimmune diseases, malignancies, or other conditions can also cause it.
In the case of Prof. Dr. Rohit Chhirolya, it is mainly concerned with the patients who may show neurological symptoms due to suspicion of involvement of the nervous system. Dr. Radhika Sarda and Dr. Souradeep Chowdhury have presented their expertise in the field of infectious diseases, having been involved in unexplained fever cases.
Hence, the priority for all the cases must be following the proper medical examination, focusing on proper tests, and referring to the appropriate expert in time.
