Introduction

The case presented involves a middle-aged woman, DC, experiencing right upper quadrant (RUQ) abdominal pain, nausea, and vomiting shortly after a large meal. Given her clinical presentation, laboratory results, and medical history, the most probable diagnosis is acute cholecystitis secondary to gallstone disease. The following analysis will elaborate on the diagnostic reasoning and propose an appropriate pharmacological treatment plan tailored to her clinical profile.

Diagnosis and Rationale

The patient’s symptomatology of sudden RUQ pain that began after a fatty meal aligns strongly with gallbladder pathology, particularly gallstone-related complications. Her nausea and one episode of vomiting further support gastrointestinal distress commonly associated with biliary colic or cholecystitis. The physical examination information indicates minimal tenderness, which does not rule out inflammation but suggests a mild presentation.

Laboratory results are essential in corroborating the clinical suspicion. The elevated WBC count (13,000/mm³) indicates an inflammatory process, likely infectious or immune-mediated. Liver function tests reveal normal total bilirubin (0.8 mg/dL) and direct bilirubin (0.6 mg/dL), with mildly elevated AST (45 U/L) and normal ALT (30 U/L), implying that hepatic involvement is limited at this stage. The alkaline phosphatase (100 U/L) is within normal limits or mildly elevated, suggesting no significant bile duct obstruction currently.

Imaging studies, although not provided, would typically show gallstones in the gallbladder lumen. The temporal relationship of symptoms after a high-fat meal and laboratory data suggest an initial episode of biliary colic progressing toward early cholecystitis. Her lack of jaundice and relatively mild labs make acute cholecystitis probable, but less likely to be complicated by bile duct obstruction or cholangitis.

Her medical history, including hypertension, diabetes mellitus, gout, and DVT, influences the treatment plan. Her current medications, particularly antihypertensives and allopurinol for gout, are well tolerated and should be considered when prescribing new medications.

Proposed Treatment Plan

The primary management approach for uncomplicated acute cholecystitis involves supportive care initially, including fasting, IV fluids, analgesia, and antibiotics. Pharmacological intervention plays a vital role in symptom relief and infection control.

Since her presentation is within 24 hours with evidence indicative of early inflammation, initiating empiric antibiotic therapy targeting common biliary pathogens (Enterobacteriaceae, anaerobes, Enterococcus spp.) is indicated. A broad-spectrum antibiotic such as ceftriaxone combined with metronidazole provides effective coverage for biliary infections. Ceftriaxone (1 g IV once daily) is a suitable choice due to its efficacy, convenient dosing, and renal elimination, which minimizes interactions with her current medications.

Metronidazole (500 mg IV every 8 hours) complements ceftriaxone by covering anaerobic pathogens often involved in biliary infections. This combination is supported by clinical guidelines recommending empiric antibiotics for acute cholecystitis cases, especially when the patient shows signs of early or mild inflammation (Kumar & Abbas, 2021).

Analgesia is essential for symptom management. Given her allergy to codeine, non-opioid analgesics such as acetaminophen (500-1000 mg orally every 6 hours as needed) can be used. If pain persists beyond initial intervention, consideration of NSAIDs, such as ketorolac (15-30 mg IV every 6 hours), could be appropriate, provided renal function and bleeding risk are assessed.

Her existing medications should be continued cautiously. Lisinopril and HCTZ may affect renal function; thus, kidney function should be monitored during IV therapy (Kaiser et al., 2020). Allopurinol therapy is unaffected but should be continued to prevent gout flares.

Once clinical improvement is observed, plans for definitive management, such as cholecystectomy, should be discussed. Antibiotics should be continued for 7-10 days or until clinical resolution.

Justification of the Plan

The recommended empiric antibiotics address common biliary pathogens and are supported by guidelines from the Infectious Diseases Society of America (IDSA, 2018). Ceftriaxone's once-daily dosing and safety profile make it suitable for outpatient or inpatient settings. Metronidazole’s anaerobic coverage complements ceftriaxone, reducing the risk of secondary infections.

Non-opioid analgesics prevent unnecessary sedation and side effects, with acetaminophen being a safe initial choice owing to reported allergies to codeine. NSAIDs like ketorolac are; effective in managing analgesia in biliary colic if tolerated and renal function allows.

Consideration of her comorbidities is crucial. Monitoring blood pressure and renal function during therapy ensures safety, especially since NSAIDs and certain antibiotics can impact renal status. Continuing her current chronic medications avoids abrupt changes that could destabilize her condition.

In summary, the diagnosis of early uncomplicated cholecystitis is supported by her clinical presentation, lab findings, and history. The proposed antibiotic regimen and supportive care align with evidence-based practices for effective symptom management, infection control, and preparation for definitive surgical treatment.
