July 2024 Critical Care Case of the Month: Community-Acquired Meningitis

Robert A. Raschke MD

The University of Arizona College of Medicine – Phoenix

Phoenix, AZ USA

History of Present Illness

A 59-year-old man was brought to our emergency department at 0300 with a possible stroke. He was last known well at 2230 the previous evening, when he complained of severe headache and took some acetaminophen before going to bed. His wife (who provided all history) noted that the patient awoke about midnight, vomited and took some naproxen. The wife next heard the patient awake at 0230, and found him back in the bathroom vomiting again, slow to respond, “mumbling” and confused. The wife was able to get the patient into their car with some difficulty and drove him to the ER.

Past Medical History, Social History, Family History

Only minimal past medical history was elicited. There was no known trauma, no fever and no recent illnesses. The patient took no prescription medications. He did not have any history of neurological disease or of substance abuse.

Physical Examination

Vitals from the ER at 0300 included: BP 157/130 mmHg, HR 101 bpm, RR 16 bpm, temperature 97.7°F.

The patient was described as “non-toxic appearing.” His eyes were open, but he was mute and didn’t obey commands. His Glascow Coma Scale was E4, V1, M5. Formal strength testing wasn’t performed, but he was observed to spontaneously move his arms. No facial asymmetry was noted.

Hospital Course

A “Stroke alert” was called based on the clinical presentation. The laboratory evaluation was significant for: WBCC 14.9x10⁹/L, hemoglobin 13.2 g/L, platelets 181x10⁹/L; Na 135 mmol/L, K 4.0 mmol/L, Cl 100 mmol/L, CO2 23 mmol/L, BUN 14 mg/dL, creatinine 0.7 mg/dL, glucose 349 mg/dL and INR 1.0. A procalcitonin was elevated at 0.8 ng/mL. Urinalysis showed >500 mg/dL glucose, moderate leukocyte esterase, WBCC 19/hpf, and no bacteria. A urine drugs of abuse screen was negative. CT head, CTA head/neck and brain perfusion scans were all negative for acute abnormalities. A virtual stroke neurologist recommended against lytics and/or thrombectomy, due to the lack of radiographic evidence of a large vessel occlusion.

The patient was admitted to the family medicine service. Ceftriaxone 1gm was administered for a presumed urinary tract infection. His temperature was retaken at 0630, at which time it had risen to 102.7°F. At 0730 the patient became agitated, diaphoretic and his SpO₂ fell to 79%. His BP was 223/139 mmHg, HR 115 bpm, and RR 53 bpm and he was emergently intubated and transferred to the ICU.

Which of the following is false regarding the clinical findings of community-acquired bacterial meningitis? (Click on the correct answer to be directed to the second of 5 pages)

1. Fifty percent of patients present within 24 hours of symptom onset.
2. The majority of patients have the classic triad of fever, stiff neck and altered mental status.
3. Ninety-five percent of patients have at least two of four findings: (headache, fever, stiff neck and altered mental status).
4. Patients may less commonly present with community-acquired hemiplegia, aphasia, seizure, and cranial nerve deficits.
5. All are true.

History of Present Illness: A 53-year-old man was admitted for acute onset of left hemiparesis, left facial droop and dysarthria witnessed by his wife (a nurse) while they were watching TV that evening. She reported the patient had no previous history of coronary artery disease or cerebral vascular disease, prior to an admission occurring three weeks earlier. The patient presented at that time with acute, severe left-sided chest pain that began while he was doing some heavy yardwork. While being evaluated in the emergency department (ED), he developed left-sided facial numbness, hemiparesis and dysarthria. A CT scan of the brain was normal. Neurological symptoms resolved before lytic therapy could be administered. Troponins and EKG were normal. A D-dimer was >20 mg/L, but a CTA of the chest showed no pulmonary embolism and was otherwise unrevealing. The chest pain resolved without specific therapy. Subsequent CTA of the head and neck and a brain MRI were both normal. Other labs drawn during that two-day hospitalization, including a CBC, complete metabolic profile, INR and aPTT, were all essentially normal. The patient was diagnosed with transient ischemic attack, atypical chest pain and new onset hypertension, and discharged on 81 mg aspirin and 2.5 mg amlodipine daily.

The patient did well over the intervening three weeks except for poor control of his hypertension, with blood pressures measured at home as high as 178/105. On the morning before his current presentation, the patient coughed up blood. The patient’s wife examined his mouth and noted several “blood blisters” of his buccal mucosa which she attributed to his poorly fitting dentures. The patient was otherwise well until the onset of stroke symptoms at 2200, after which he  complained of diffuse headache. 

Past Medical History: The patient had no known allergies. He had a history of emphysema, GERD and hypercholesterolemia and was taking rosuvastatin, esomeprazole and inhaled fluticasone/umeclidinium/vilanterol in addition to amlodipine and aspirin. He had a remote history of major trauma resulting in asplenia. He didn’t smoke, vape, drink alcohol excessively or use drugs. He worked as a truck driver.

Physical Examination: Initial physical examination was significant for HR 117 bpm, RR 18 bpm, temp. 36.5°C, BP 169/99 mmHg. His Glascow Coma Scale (GCS) was 14 and he was dysarthric, with a rightward gaze preference and a dense L hemiplegia. Ecchymoses of his left knee and right shoulder were noted. A stat CT brain showed a 6x4x4cm intraparenchymal hematoma centered on the right basal ganglia, effacing the right lateral ventricle and causing 6mm of midline shift. It was confirmed that the patient had not taken any antithrombotic medications or clopidogrel. Admission labs demonstrated a WBCC 22.8 x10³/uL, Hb 12.8 g/dL and platelet count of 64 x10³/uL. An automated five-part differential (neutrophils, lymphocytes, monocytes, basophils, and eosinophils) was normal. The INR was 2.2 and aPTT 38 secs. Fibrinogen was 62 mg/dL and a D-dimer >20 ml/L. A complete metabolic profile was unremarkable.

Routine management of acute hemorrhagic stroke includes which of the following except? (Click on the correct answer to be directed to the )

1. Rapid control of systolic blood pressure to levels <140mmHg using intravenous antihypertensives if necessary.
2. Rapid reversal of antithrombotic effects of medications such as warfarin with four-factor prothrombin complex concentrate (4F PCC), and Xa inhibitors with andexanet alpha or 4FPCC.
3. Platelet transfusion to maintain platelet count >100 x10³/uL in patients with thrombocytopenia.
4. Platelet transfusion to restore platelet function in patients with normal platelet counts, but platelet dysfunction due to aspirin or other antiplatelet drugs.
5. Neurosurgical consultation.
