PURPOSE: Paclitaxel is associated with both an acute pain syndrome (P-APS) and chronic chemotherapy-induced peripheral neuropathy (CIPN). Given that extensive animal data suggest that minocycline may prevent chemotherapy-induced neurotoxicity, the purpose of this pilot study was to investigate the efficacy of minocycline for the prevention of CIPN and the P-APS. METHODS: Patients with breast cancer were enrolled prior to initiating neoadjuvant or adjuvant weekly paclitaxel for 12 weeks and were randomized to receive minocycline 200 mg on day 1 followed by 100 mg twice daily or a matching placebo...

We describe a case of lymphocytic thrombophilic arteritis in a 15-year-old girl who had previously taken minocycline for a year. Cutaneous polyarteritis nodosa and lymphocytic thrombophilic arteritis share many features and may both be triggered by minocycline. There may be a long latency between drug exposure to minocycline and development of disease.

PURPOSE: A case of ocular pythiosis successfully treated with surgery and intraocular and oral minocycline is reported. SUMMARY: A 30-year-old man who wore corrective contact lenses traveled to Brazil and Colombia where he swam in salt and fresh waters while wearing contact lenses. He sought treatment at an emergency department after 2 weeks of suffering with a painful corneal ulcer, redness, and loss of vision in his right eye that had been treated at other centers with ophthalmic moxifloxacin for 10 days and with fortified topical antibiotics (amikacin and vancomycin) for 2 days...

AIMS: We previously demonstrated that intrathecal IL-1β upregulated phosphorylation of p38 mitogen-activated protein kinase (P-p38 MAPK) and inducible nitric oxide synthase (iNOS) in microglia and astrocytes in spinal cord, increased nitric oxide (NO) release into cerebrospinal fluid, and induced thermal hyperalgesia in rats. This study investigated the role of spinal glutamatergic response in intrathecal IL-1β-induced nociception in rats. METHODS: The pretreatment effects of MK-801 (5 μg), minocycline (20 μg), and SB203580 (5 μg) on intrathecal IL-1β (100 ng) in rats were measured by behavior, Western blotting, CSF analysis, and immunofluorescence studies...

Peripheral nerve injury induces substantial molecular changes in the somatosensory system that leads to maladaptive plasticity and cause neuropathic pain. Understanding the molecular pathways responsible for the development of neuropathic pain is essential to the development of novel rationally designed therapeutics. Although lipids make up to half of the dry weight of the spinal cord, their relation with the development of neuropathic pain is poorly understood. We aimed to elucidate the regulation of spinal lipids in response to neuropathic peripheral nerve injury in mice by utilizing matrix-assisted laser desorption/ionization imaging mass spectrometry, which allows visualization of lipid distribution within the cord...

Tochukwu C Ikpeze, Addisu Mesfin
Spinal cord injuries (SCIs) are sustained by more than 12 500 patients per year in the United States and more globally. The SCIs disproportionately affect the elderly, especially men. Approximately 60% of these injuries are sustained traumatically through falls, but nontraumatic causes including infections, tumors, and medication-related epidural bleeding have also been documented. Preexisting conditions such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis can render the spine stiff and are risk factors as well as cervical spondylosis and ensuing cervical stenosis...

A 63-year-old man with follicular lymphoma was administered standard R-CHOP chemotherapy. Six days after the second course of chemotherapy, the patient developed fever and chills. Blood cultures yielded rod-shaped gram-negative bacteria, but no further identification was obtained. High fever and chills returned on the fifth and sixth days after the third and fourth courses of R-CHOP, respectively. These blood cultures were also positive. Since we detected spiral-shaped gram-negative rods, we performed a prolonged culture during the febrile period after the fourth course of R-CHOP...

We examined the in vitro activity of minocycline against 103 Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae isolates and found approximately half had susceptible (26%) or intermediate (26%) MICs. For a subset of 35 isolates, susceptibility was highest to tigecycline (71% FDA vs. 20% EUCAST) followed by minocycline (14%) and then doxycycline (6%).

Introduction: For chronic prosthetic joint infections (PJI), complete removal of the infected prosthesis is necessary in order to cure the infection. Unfortunately, a subgroup of patients is not able to undergo a revision surgery due to high surgical risk. Alternatively, these patients can be treated with antibiotic suppressive therapy (AST) to suppress the infection. Aim: To evaluate the efficacy and tolerability of AST. Methods: We retrospectively collected data (period 2009-2015) from patients with a PJI (of hip, knee or shoulder) who were treated with AST at the University Medical Center Groningen, the Netherlands...

Microglia are essential in developmental processes and maintenance of neuronal homeostasis. Experimental axotomy of motor neurons results in neurodegeneration, and microglia in motor nuclei become activated and migrate towards injured neurons. However, whether these activated microglia are protective or destructive to neurons remains controversial. In the present study, we transected the hypoglossal nerve in BALB/c mice, causing activating transcription factor 3 (ATF3) and growth associated protein 43 (GAP43) induction, and partial neuronal death...

BACKGROUND: Central pain (CP) is a common clinical problem in patients with spinal cord injury (SCI). Recent studies found the pathogenesis of CP was related to the remodeling of the brain. We investigate the roles of iron overload and subsequent microglia activate in the remodeling of the brain after SCI. METHODS: An SCI-induced CP model was established in Sprague-Dawley rats that were randomly assigned to SCI, sham operation, deferoxamine (DFX), minocycline, and nitric oxide synthase inhibitor treatment groups...

Objectives. Slowly growing mycobacteria (SGM) are prevalent worldwide and cause an extensive spectrum of diseases. Methods. In this study, the antimicrobial susceptibility of 33 reference strains of SGM to 19 antimicrobial agents was tested using a modified microdilution method. Results. Cefmetazole (32/33) and azithromycin (32/33) exhibited the highest antimicrobial activity, and dapsone (9/33) exhibited the lowest activity against the tested strains. Cefoxitin (30/33), cefoperazone (28/33), and cefepime (28/33) were effective against a high proportion of strains, and macrolides were also highly effective as well as offering the benefit of convenient oral administration to patients...

Drug-induced pauci-immune crescentic glomerulonephritis has been described with several agents, including propylthiouracil, minocycline, D-penicillamine, and hydralazine. We present the case of a 60-year-old man who presented with rapidly progressive glomerulonephritis in the setting of recent use of trimethoprim-sulfamethoxazole complicated by the development of the Stevens-Johnson syndrome, and was found to have biopsy-proven pauci-immune crescentic glomerulonephritis and undetectable anti-neutrophilic cytoplasmic antibodies...

Neuropathic pain occurs after peripheral nerve damage, inflammation or infection. In this situation, microglial cells become activated and play a key role in producing pain. Minocycline (microglia inhibitor), was reported to reduce pain when used preventively. However, it seems that, when used after nerve injury, results in its pain reducing effects are different. In this regard, to assess the pain reducing differences of minocycline, neuropathic pain was induced by the ligation of the sciatic nerve in the rat which is recognized as chronic constriction injury (CCI) and minocycline was administered before and after sciatic nerve injury...

Kidney diseases need specialized health care and still are a reason of death. There is a large body of evidence that indicates minocycline possesses some cytoprotective effects beside of antibacterial properties. In this review, we aimed to explain cytoprotective mechanisms and kidney protection of minocycline. In order to find the effects of minocycline on kidney diseases a systematic literature search was performed, according to the guidelines proposed at the PRISMA statement in the electronic databases, including: PubMed, Scopus, and Web of Science up to August 2016, using the term 'minocycline' combined either by 'kidney' or 'renal' and published in English language...

Glaucoma is a leading cause of blindness, characterized by retinal ganglion cell (RGC) loss and optic nerve (ON) damage. Cumulative evidence suggests glial cell involvement in the degeneration of the ON and RGCs. We analyzed the contribution of microglial reactivity to early axoglial alterations of the ON in an induced model of ocular hypertension. For this purpose, vehicle or chondroitin sulfate (CS) were weekly injected into the eye anterior chamber from Wistar rats for different intervals. The amount of Brn3a(+) RGC significantly decreased in CS-injected eyes for 10 and 15 (but not 6) weeks...

Botulinum neurotoxin type A (BoNT/A) and minocycline are potent drugs used in clinical therapies. The primary molecular mechanism of BoNT/A is the cleavage of SNARE proteins, which prevents cells from releasing neurotransmitters from vesicles, while the effects of minocycline are related to the inhibition of p38 activation. Both BoNT/A and minocycline exhibit analgesic effects, however, their direct impact on glial cells is not fully known. Therefore, the aim of the present study was to determine the effects of those drugs on microglial and astroglial activity after lipopolysaccharide (LPS) stimulation and their potential synergistic action...

A stroke or cerebrovascular accident is a serious, life-threatening medical condition that occurs when the blood supply to part of the brain is severely reduced or cut off, depriving brain tissue of oxygen and nutrients. Studies suggested that level of gelatinases (MMP-2 and MMP-9) usually increases in the brain after stroke. The elevated activity of gelatinases plays the deleterious role in ischemic stroke, hemorrhagic stroke and perinatal hypoxic-ischemic brain injury. Therefore, matrix metalloproteinase (MMP)-2 and MMP-9 inhibition have therapeutic importance in stroke condition...
