Acne vulgaris (acne) is a chronic inflammatory disease prevalent among adolescents and adults, with significant psychological effects. The aetiology of acne is multifactorial. Several pathophysiological associations have been identified in which Propionibacterium acnes plays a major role. This bacteria primarily affects areas containing oil glands including the face, back and trunk, where it causes the formation of seborrhoea and inflammatory lesions. The treatment methods currently in place have side effects...

BACKGROUND: Periprosthetic tissue cultures, sonication and synovial fluid cultures remain the gold standard for prosthetic joint infection (PJI) diagnosis. However, some 15-20% culture-negative PJI are still reported. Therefore, there is the need for other diagnostic criteria. One point of concern relative to the different definitions of PJI is as to the inclusion of the c-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR) as diagnostic criteria for PJI despite them being non-specific inflammatory blood tests...

Palladacycle complex DPPE 1.2 was previously reported to inhibit the in vitro and in vivo infection by Leishmania (Leishmania) amazonensis. The aim of the present study was to compare the effect of DPPE 1.2, in association with heat-killed Propionibacterium acnes, on L. (L.) amazonensis infection in two mouse strains, BALB/c and C57BL/6, and to evaluate the immune responses of the treated animals. Foot lesions of L. (L.) amazonensis-infected mice were injected with DPPE 1.2 alone, or associated with P. acnes as an adjuvant...

Although there have been few formal studies, scarring is a known bothersome companion of acne vulgaris. We performed a prospective study of subjects consulting a dermatologist for active acne to assess the frequency of acne scarring. Investigators performed a short questionnaire on all acne patients seen at their office for one consecutive 5-day work week to assess scar frequency. Additionally, the first four subjects with acne scars identified were enrolled for a second phase (scar cohort) of the study during which the investigator collected further medical history and performed a clinical evaluation and the patient completed a self-administered questionnaire about scar perceptions and impact on quality of life...

Although a number of facts on the physiopathological mechanisms of acne are now well established, it is still unclear what triggers the severity of this inflammatory disease of the sebaceous follicle. Thus, could the severity of the acne be somehow linked to different strains of its main bacterium, Propionibacterium acnes? We know that there are several types of P. acnes, and a study (1) has recently shown that different strains of P. acnes could up-regulate or down-regulate in vitro inflammatory keratinocyte response...

BACKGROUND: Modic changes (inflammatory-like changes visible on magnetic resonance imaging [MRI] scans of a vertebral end plate) are common and are associated with low back pain, but their origin is unclear. To our knowledge, there have been no previous in vivo animal models of Modic changes. We hypothesized that Modic changes may be related to Propionibacterium acnes. METHODS: Ten New Zealand White rabbits were injected percutaneously with 1 mL of P. acnes (1.6 × 10 colony forming units/mL) into the subchondral bone superior to the L4-L5 and L5-L6 discs; 10 other control rabbits received sham injections at L4-L5 and 1 mL of normal saline solution (vehicle) at L5-L6...

The present case exemplified the detrimental traits of prosthetic valve endocarditis caused by Propionibacterium acnes. As a baby, the patient had a congenital cardiac defect with truncus arteriosus type I with interrupted aortic arch and open ductus Botalli, and had undergone several operations. However, at 18 months after a Bentall procedure performed 29 years later he presented with major prosthetic dehiscence due to endocarditis. The patient underwent a high-risk reoperation for a re-do Bentall procedure and was treated postoperatively with intravenous antibiotics consisting of vancomycin for five weeks and penicillin and rifampicin each for six weeks...

OBJECTIVE: To compare a series of monomicrobial Propionibacterium acnes (P. acnes) knee and hip periprosthetic joint infection (PJI) cases with cases of polymicrobial PJI which included P. acnes. We hypothesized that the presence of a polymicrobial P. acnes infection would lead to worse outcomes than those in cases of monomicrobial P. acnes PJI. METHODS: Retrospective multicentre study. All patients with hip or knee PJIs including P. acnes diagnosed from August-2002 to July-2013 in two university hospitals were included...

The human commensal bacterium Propionibacterium acnes (P. acnes) resides in the pilosebaceous duct of the skin. It has been long implicated in the pathogenesis of acne, although its exact role in the development of inflammatory acne lesions and in the formation of the microcomedo in the early stages of acne remains controversial. The worldwide prevalence of antibiotic-resistant P. acnes is increasing, with rates varying in different parts of the world. The reason for the difference in the antibiotic resistance patterns of P...

Acne vulgaris is a chronic inflammatory skin condition classified by the Global Burden of Disease Study as the eighth most prevalent disease worldwide. The pathophysiology of the condition has been extensively studied, with an increase in sebum production, abnormal keratinization of the pilosebaceous follicle, and an inflammatory immune response all implicated in its etiology. One of the most disputed points, however, is the role of the gram-positive anaerobic bacterium Propionibacterium acnes in the development of acne, particularly when this organism is also found in normal sebaceous follicles of healthy skin...

Neglected and underestimated in the past, Propionibacterium acnes is currently the most prevalent organism associated with deep prosthetic infections around the shoulder. Surprisingly, it has never been reported as a cause of infection in the hand. Here we report a case of a late presentation of a P. acnes infection in a metacarpophalangeal joint replacement, resulting in chronic low-grade pain with movement. The patient underwent a 2-stage revision, with initial removal of the prosthesis. Positive cultures for P...
