From the Guidelines
The next best step in managing a patient with fever and night sweats, despite normal TSH, negative HIV screen, and negative Quantiferon test, is to conduct a comprehensive history and physical examination, including evaluation of B symptoms, followed by additional targeted laboratory testing and imaging as recommended by the NCCN guidelines for Hodgkin lymphoma 1.
Key Components of Evaluation
- Comprehensive history and physical examination to assess for B symptoms (unexplained fever >38°C, drenching night sweats, or weight loss >10% of body weight within 6 months) and other disease-related symptoms such as fatigue, pruritus, and alcohol intolerance 1.
- Laboratory tests should include a complete blood count (CBC) with differential, erythrocyte sedimentation rate (ESR), comprehensive metabolic panel, lactate dehydrogenase (LDH), and liver function tests (LFTs) as outlined in the NCCN guidelines for Hodgkin lymphoma 1.
- Imaging studies such as a diagnostic CT scan (contrast-enhanced) or PET/CT scan (skull base to mid-thigh) may be useful in selected cases, especially if there is suspicion of lymphoma or other malignancies 1.
Considerations for Further Testing
- If lymphadenopathy is present, a lymph node biopsy should be considered for definitive diagnosis 1.
- Screening for hepatitis B and C, as well as HIV, is recommended as part of the initial workup for patients with suspected lymphoma 1.
- Given the patient's symptoms of fever and night sweats, which are suggestive of B symptoms, a thorough evaluation for lymphoma, including classical Hodgkin lymphoma (CHL), should be undertaken, following the guidelines for diagnosis, treatment, and follow-up as recommended by ESMO and NCCN 1.
Approach to Diagnosis
- The approach should be systematic and guided by clinical findings, considering the broad differential diagnosis of fever and night sweats, which includes infections, malignancies (particularly lymphoma), and autoimmune disorders that were not excluded by the initial tests performed 1.

Next Steps in Managing a Patient with Fever and Night Sweats
- The patient's normal TSH, negative HIV screen, and negative Quantiferon test results indicate that the cause of their symptoms may not be related to thyroid dysfunction, HIV infection, or latent tuberculosis 2, 3.
- Given the absence of clear indications for thyroid dysfunction or other specific infections, a comprehensive diagnostic approach is necessary to identify the underlying cause of the patient's fever and night sweats 4, 5.
- The evaluation of diagnostic tests, including their anatomy, phases, and statistical treatment of data, is crucial in determining the best course of action for this patient 5.
- Considering the high base rates of many symptoms, the type of population studied, and the methods of symptom detection, a thorough assessment of the patient's symptoms and medical history is essential 6.
- A step-by-step approach, including the selection of an adequate patient population, determination of diagnostic power, and relation of new tests to current diagnostic tools, should be employed to guide the diagnostic process 4.
- The patient's symptoms, such as fever and night sweats, should be thoroughly evaluated, including their recency of onset, episodicity, duration, and severity, as well as their impact on the patient's functional status and health-related quality of life 6.
