Clinical management of carbamazepine intoxication during anti-tubercular treatment: a case report

We describe a 67-year-old man with medical history of focal post-stroke seizure and type 2 diabetes mellitus treated with carbamazepine, clobazam, gliclazide, insulin glargine, and omeprazole we visited for the onset in the last 7 days of asthenia, cough with mucus, breathing difficulty, chest pain, and weight loss. After clinical and laboratory tests, pulmonary tuberculosis was diagnosed, and a treatment with isoniazid, ethambutol, pyrazinamide rifampicin, and pyridoxine was started. Therapeutic drug monitoring of tuberculosis treatment documented that all drugs were in normal therapeutic range. Four days after the beginning of the treatment, we documented the improvement of fever, and three days later the patient showed sleepiness, visual disorder and asthenia. Clinical and pharmacological evaluation suggested a carbamazepine toxicity probably related to a drug interaction (Drug Interaction Probability Scale score = 6). The impossibility to switch carbamazepine for another antiepileptic drug, due to a resistant form of seizure, induced the discontinuation of tuberculosis treatment, resulting in the normalization of serum carbamazepine levels in one day (10 µg/ml) and in the worsening of fever, requiring a new clinical and pharmacological evaluation. The titration dosage of carbamazepine and its therapeutic drug monitoring allowed to continue the treatment with both antitubercular drugs and carbamazepine, without the development of adverse drug reactions. To date, tuberculosis treatment was stopped and clinical evaluation, radiology and microbiology assays documented the absence of tubercular infection and no seizures appeared (carbamazepine dosage 800 mg/bid; serum levels 9.5 µg/ml)

Aeromonas sobria Induced Sepsis Complicated with Necrotizing Fasciitis in a Child with Acute Lymphoblastic Leukemia

Aeromonas species are gram negative and able to induce systemic diseases (i.e., gastrointestinal, respiratory, and cardiovascular, diseases, in addition to infection of brain and soft tissues). In this study, we describe the development of necrotizing fasciitis in a young immunocompromised girl, with a low response to drug treatment and who died after some months

Group B streptococcal meningitis in an adult: A possible complication of olecranon bursitis

Background: We report a man with septic olecranon bursitis who had an early development of meningitis. Case Summary: A 74-year-old man presented to the emergency room with malaise, headache, mental confusion, a fever unsuccessfully treated with oral NSAIDs and ice, and with a 10-day history of pain and swelling in his right elbow. Clinical and laboratory evaluation excluded other causes and microbiological evaluation documented a S. agalactiae infection. Antibiotic treatment induced a rapid improvement, without the development of side effects. Conclusion: This is the first report on olecranon bursitis and concomitant meningitis related to S. agalactiae infection

The Role of a Rapid Prevention of <i>Ralstonia pickettii</i> Growth during Dialysis in a Frail Patient

Ralstonia pickettii is an opportunistic bacillus found in Pseudomonas species, with the ability to induce systemic infections. We report the case of a 69-year-old man, with a clinical history of myeloma, Type IIdiabetes, renal failure (grade IV), and colon cancer, that developed a severe bacterial infection, with acute asthenia and a fever, that appeared at the end of dialysis. Using theMALDI-TOF technology, the bacillus Ralstonia pickettii was identified, and an antimicrobial treatment was quickly started with a rapid microbiological remission

When Clinical History Addresses the Diagnosis in a Case of Uncommon Meningitis

Migraine pain is usually cyclic and may be evocated by inflammatory mediators released around the nerves and blood vessels. Acute migraine pain is more common in women than in men, and correlates with age. In this study, we report the development of an acute migraine attack in a young man (32 years old), which led to his admission to the emergency department. The positive functional brain changes recorded by electroencephalogram (EEG) during the migraine attack, and the non-contrast brain computed tomography scan showed the presence of an arachnoid cyst, which explained the acute migraine attack inducing a misdiagnosis. Using the case described herein, we aim to draw the attention of clinic/scientific communities toward the existence of brain infections in absence of the typical symptoms (e.g., fever and/or rigor nucalis). Considering this case, we propose that when a diagnosis is uncertain the invasive liquor test should be performed

Liver Damage and microRNAs: An Update

One of the major organs in the body with multiple functions is the liver. It plays a central role in the transformation of macronutrients and clearance of chemicals and drugs. The serum biomarkers often used to indicate liver damage are not specifically for drug-induced liver injury (DILI) or liver injury caused by other xenobiotics, nor for viral infection. In this case, microRNAs (miRNAs) could play an exciting role as biomarkers of specific liver damage. In this review, we aimed to update the current literature on liver damage induced by drugs, as acute conditions and viral infections mediated by the hepatitis B virus (HBV) linked these two conditions to advanced research, with a focus on microRNAs as early biomarkers for liver damage. The undoubtable evidence that circulating miR-122 could be used as a human biomarker of DILI came from several studies in which a strong increase of it was linked with the status of liver function. In infancy, there is the possibility of an early miRNA detection for hepatitis B virus infection, but there are a lack of solid models for studying the HVB molecular mechanism of infection in detail, even if miRNAs do hold unrealized potential as biomarkers for early detection of hepatitis B virus infection mediated by HBV

Expression of MMP-2, MMP-9, and NGAL in Tissue and Serum of Patients with Vascular Aneurysms and Their Modulation by Statin Treatment: A Pilot Study

Background: Matrix metalloproteinases (MMPs) are involved in vascular wall degradation, and drugs able to modulate MMP activity can be used to prevent or treat aneurysmal disease. In this study, we evaluated the effects of statins on MMP-2, MMP-9, and neutrophil gelatinase-associated lipocalin (NGAL) in both plasma and tissue in patients with aneurysmal disease. Methods: We performed a prospective, single-blind, multicenter, control group clinical drug trial on 184 patients of both sexes &gt;18 years old with a diagnosis of arterial aneurysmal disease. Enrolled patients were divided into two groups: Group I under statin treatment and Group II not taking statins. In addition, 122 patients without aneurysmal disease and under statin treatment were enrolled as a control group (Group III). The expression of MMPs and NGAL in plasma was evaluated using ELISA, while their expression in endothelial tissues was evaluated using Western blot. Results: The ELISA test revealed greater plasma levels (p &lt; 0.01) of MMPs and NGAL in Groups I and II vs. Group III. Western blot analysis showed higher expression (p &lt; 0.01) of MMPs and NGAL in Group II vs. Group I, and this increase was significantly higher (p &lt; 0.01) in patients treated with low potency statins compared to high potency ones. Conclusions: MMPs and NGAL seem to play a major role in the development of aneurysms, and their modulation by statins suggests that these drugs could be used to prevent arterial aneurysmal disease

Comparison of Allplex™ 2019-nCoV and TaqPath™ COVID-19 Assays

The clinical presentation of COVID-19 is non-specific, and to improve and limit the spread of the SARS-CoV-2 virus, an accurate diagnosis with a robust method is needed. A total of 500 nasopharyngeal swab specimens were tested for SARS-CoV-2. Of these, 184 samples were found to be positive with Allplex™ 2019-nCoV Assay, which is fully automated. All the positive samples were retested with TaqPath™ COVID-19 CE-IVD RT-PCR Kit (after this, referred to as TaqPath™ COVID-19), semi-automated. The comparison of RT-qPCR for SARS-CoV-2 genes target points shows only one target point in common, the N gene. Therefore, the N gene was used to compare both assays. We noticed different Ct values between the tests. Therefore, samples were divided into four groups depending to the Ct value results: (1) Ct 35. TaqPath™ COVID-19 Kit reconfirmed the results obtained from Allplex™ 2019-nCoV Assay. In conclusion, both the Allplex™ 2019-nCoV assay and TaqPath™ COVID-19 tests accurately confirm the diagnosis of SARS-CoV-2 infection. Even if TaqPath™ COVID-19 has a semi-automated workflow, it does not introduce bias in the diagnostic screening of SARS-CoV-2, and it supports the indirect identification of variants of concern to undergo sequencing
