Treatment Plan for Macrocytosis, Blocked Ear, Fatigue, and Prostate Issues

Immediate Management Priorities

The most critical immediate action is to check B12 and folate levels to address the macrocytosis and fatigue, while treating the blocked ear with cerumenolytic agents or irrigation, and continuing specialist management of the prostate enlargement without initiating new treatment based solely on the PSA elevation. 1, 2

1. Macrocytosis and Fatigue Management

Diagnostic Workup

  • Check serum B12 and folate levels immediately given the MCV of 105 (elevated from 104) and ongoing fatigue/weakness 1, 2
  • The combination of macrocytosis (MCV 105), alcohol consumption, and fatigue strongly suggests either B12/folate deficiency or alcohol-related bone marrow suppression 1, 2
  • High altitude living (5,000 feet in Mexico) may contribute to fatigue but does not explain macrocytosis 1

Treatment Approach

  • If B12 deficiency confirmed: Start cyanocobalamin 1,000 mcg daily orally 1
  • If folate deficiency confirmed: Initiate folate supplementation 2
  • Critical caveat: Never give folate alone without checking B12 first, as folic acid in doses above 0.1 mg daily may mask pernicious anemia while neurological damage progresses 2
  • Counsel on alcohol reduction, as this is a reversible cause of macrocytosis 1, 2

2. Blocked Ear Management

Treatment

  • Prescribe cerumenolytic agents (such as carbamide peroxide drops) or perform in-office irrigation for the blocked left ear 3
  • The patient admitted to not using previously prescribed treatment, so emphasize importance of compliance 3
  • If simple wax impaction, this should resolve within days of proper treatment 3

3. Elevated PSA and Prostate Management

Critical Context

The PSA of 9.4 should NOT trigger immediate intervention in this patient for several important reasons:

Confounding Factors for PSA Elevation

  • The elevated neutrophil count (8.0) suggests possible subclinical prostatic inflammation, which can significantly elevate PSA 4, 5, 6
  • Studies show that chronic prostatitis can elevate PSA by 36-40%, and treatment of inflammation can normalize PSA in nearly half of affected patients 4, 7, 8
  • PSA determination should be obtained after complete clinical resolution of any inflammation to exclude false elevation 8
  • White blood cell count is positively associated with benign prostatic hyperplasia and can confound PSA interpretation 6

Appropriate Management Strategy

  • Continue with scheduled urologist telephone appointment in April 2026 as planned 3
  • The patient is already under specialist care with documented prostate enlargement on 3 prior MRI scans 3
  • Do NOT initiate hormonal therapy or additional interventions based solely on PSA elevation 3
  • For patients with known benign prostatic hyperplasia under specialist care, annual follow-up with repeat evaluation is appropriate 3

When PSA Should Trigger Action

According to guidelines, a rising PSA after definitive treatment (surgery/radiation) requires specific criteria before intervention 3:

  • PSA > 0.2 ng/ml after prostatectomy (not applicable here) 3
  • PSA doubling time < 12 months suggesting aggressive disease 3
  • Development of symptoms or documented metastases 3, 9

This patient has none of these criteria - he has known benign enlargement, not post-treatment recurrence 3

Repeat PSA Testing

  • Recheck PSA after treating any inflammation and after 4-6 weeks of B12/folate supplementation 4, 5, 8
  • If neutrophil count normalizes and PSA remains elevated, this provides more accurate baseline for urologist evaluation 4, 8

4. Follow-Up Timeline

Immediate (1-2 weeks)

  • Treat blocked ear 3
  • Order B12 and folate levels 1, 2
  • Begin alcohol reduction counseling 1, 2

Short-term (4-6 weeks)

  • Recheck CBC to assess MCV response to supplementation 1, 2
  • Repeat PSA after inflammation resolution 4, 8
  • Assess symptom improvement (fatigue, weakness) 1, 2

Medium-term (3-4 months)

  • Continue monitoring macrocytosis response 1, 2
  • Urologist appointment as scheduled (April 2026) 3

Key Clinical Pitfalls to Avoid

  1. Do not start folate without checking B12 first - risks masking pernicious anemia with progressive neurological damage 2

  2. Do not initiate prostate cancer treatment based on PSA alone in a patient with known BPH and possible inflammation 4, 5, 8

  3. Do not attribute all fatigue to altitude - the macrocytosis requires investigation regardless of living situation 1, 2

  4. Do not ignore the elevated neutrophil count - this suggests inflammation that can confound PSA interpretation 4, 6, 7

  5. Do not bypass the scheduled urologist appointment - specialist continuity of care is essential for proper prostate management 3
