buprenorphine and Skin-Diseases

Our understanding of the long-term safety of prenatal exposure to opioid maintenance treatment (OMT) is insufficient. We compared childhood morbidity (0-3 years) between OMT-exposed and relevant comparison groups.. Nation-wide, registry-based cohort study. Registries on reproductive health, addiction treatment, hospitalization and death were linked using identification numbers.. The Czech Republic (2000-14).. Children with different prenatal exposure: (i) mother in OMT during pregnancy (OMT; n = 218), (ii) mother discontinued OMT before pregnancy (OMT-D; n = 55), (iii) mother with opioid use disorder, but not in OMT during pregnancy (OUD; n = 85) and (iv) mother in the general population (GP) (n = 1 238 452) MEASUREMENTS: Episodes of hospitalization were observed as outcomes. Information on in-patient contacts, length of stay and diagnoses (International Classification of Diseases version 10) were assessed. Binary logistic regressions were conducted to estimate the associations between OMT exposure and the outcomes, crude and adjusted for the socio-economic status and smoking.. No significant differences were found in the overall proportion of hospitalization among OMT-exposed children, children of OMT-D and children of women with OUD [54.1%, 95% confidence interval (CI) = 47.3-60.1%; 47.3%, 95% CI = 33.9-61.1%; 51.8%, 95% CI = 40.7%-62.6%], while the proportion was significantly lower (35.8%, 95% CI = 35.7-35.8%) in the GP. There were no significant differences in risk of specific diagnoses between OMT-exposed children, children of OMT-D and children of women with OUD. In the adjusted analyses, differences between OMT-exposed and children in the GP were still present for infections and parasitic diseases (OR = 2.0, 95% CI = 1.4-2.7), diseases of the digestive system (OR = 1.7, 95% CI = 1.2-2.6) and diseases of the skin and subcutaneous tissue (OR = 1.9, 95% CI = 1.2-3.2).. This study did not find clear evidence for an increase in risk of morbidity during the first 3 years of life in children with prenatal opioid maintenance treatment exposure compared with children of women who discontinued such treatment before pregnancy or suffered from opioid use disorder without this treatment. Compared the general population, there appears to be an increased risk of hospitalizations for infectious, gastrointestinal and skin diseases.

High dose buprenorphine (HDB), commonly known as Subutex(®), is nowadays largely prescribed as a replacement therapy for major opiate dependence. Its sublingual administration allows a decrease in the withdrawal syndrome accompanying opiate abuse cessation. Over the past few decades, epidemiological data on people on replacement therapy have emphasized an increase in the misuse of Subutex(®) and more specifically intravenous injections of HDB. These growing practices pave the way to major physical consequences or even death. Several studies have highlighted the infectious, vascular, venous and arterial (pseudo-aneurysm) complications stemming from this habit. Among the possible vascular complications, we can notice the presence of abscess, venous thrombosis, phlegmons, skin necrosis, cellulite, and profound and superficial thrombophlebitis at injection sites. These can evolve into chronic edemas of the tips and subcutaneous nodules. The Popeye syndrome is one of the possible complications of this misuse. This syndrome is characterized by the swelling of both sides of the forearms and hands. These edemas tend to become persistent and to be paired with tissue changes such as skin thickening. Besides, the increase in the hands volume can occur bilaterally or sometimes in an asymmetrical way, accentuated on the hand of the non-dominant limb. This syndrome does not decrease, or just a little, after the stoppage of injections. It can have a psychological, social, psychopathological and esthetic impact.. In this article, we will focus on the clinical case of a 43-year-old man, who is hospitalized in an addictology unit for massive injections of HDB. This patient suffers from a Popeye syndrome as well as from an alcoholic dependence.. Following the description of psychopathological disorders, our analysis will originate from a clarification relative to the specificities of the practice of intravenous HDB injection to better sharpen the understanding of these misuses in their psychopathological and clinical aspects. We will discuss some proposals for interventions aiming at taking better care of the people suffering from a drug addiction characterized by the injection of HDB replacement therapy.. Adam requested an admission in an addictology ward for treatment of a self-medication by Subutex started 4 years ago. A certain awkwardness can be perceived when he lays his highly damaged and marked hands on the desk. His upper limbs, thus on display, have tripled in volume: this indicates the presence of a Popeye syndrome, consequence of repeated Subutex injections. These observations lead us to question the function and the sense of this injection behavior in the mental economy, as this repeated behavior engages the body specifically. This bruised body, marked with repeated injection holes has become a place of inscription, of representation that shows the impossibility to access other ways of expression. In this sense, taking action is becoming an act of speech. Within this speech, we can notice the existence of a profound state of uneasiness. To put up with the painful feeling of inner emptiness that is calling for a necessary filling, aiming at re-establishing a frail balance, Adam appeals to repeated injections. However, when the tortured body signifies its incapacity to receive an ultimate injection, thus showing its limits and the destruction it is undergoing, it is no longer possible to resort to Subutex injections. As a consequence, Adam came up with the idea of quitting. The withdrawal was initiated by himself and not coupled with medical care. It has led him to feel a gap, beyond the physical uneasiness. Adam has tried to fill in this unbearable feeling of empty body with tobacco, alcohol and food. The body, highly mobilized, translates the presence of a physical conflict where a massive mental anxiety is expressed in a hidden way. During the interview, Adam also addressed the repetitive familial pattern and the transgeneration effects. He seems to be fully aware of these.. Several perspectives can be addressed as part of Adam's treatment and especially cognitive-behavioral therapies as they could prove to be of a certain interest. The aim of this therapy would thus be to assess the motivation for change in order to begin a psychotherapeutic work based on personal adherence to the cessation of this misuse. This could be set up in parallel with an anxiety management work.. A better understanding and an extensive knowledge of the possible complications linked to the misuse of HDB seems necessary to sensitize and better inform people who suffer from high-risk behaviors and also to enable a more adapted care.

i.v. buprenorphine hydrochloride (Subutex) misuse has been creating a number of medical complications, and cutaneous manifestations such as soft tissue infection are one of the commonest consequences. Between January 2004 and December 2006, amongst 130 i.v. buprenorphine abusers who presented to the National University Hospital, Singapore, cutaneous complications were identified in 45 patients (prevalence, 31%) with cellulitis and skin abscess being the commonest complications. Tissue and blood culture were positive in 19 (42%) patients and Methicillin-sensitive Staphylococcus aureus was the commonest microbiological isolate (20%). Univariate linear regression revealed significant relationships between body temperature (P = 0.03), heart rate (P = 0.02), respiratory rate (P < 0.001), total peripheral white cell count (P = 0.011), absolute neutrophil count (P < 0.001) and serum C-reactive protein (CRP) level (P < 0.001) on admission and through the duration of hospitalization. In multivariate analysis, respiratory rate on admission remained significantly associated with longer duration of hospitalization (P = 0.01). i.v. cloxacillin, i.v. crystallized penicillin and oral cloxacillin were the most commonly prescribed antibiotics while 11 (24%) patients required surgical treatment. The mean duration of hospitalization was 8 +/- 11 days and repeated cutaneous complications occurred in eight (18%) patients. In conclusion, cutaneous complications are common among i.v. buprenorphine users. Respiratory rates on admission predict duration of hospital stay. A high index of suspicion coupled with a correct choice of antibiotics based on local bacteriological surveillance is necessary in an attempt to reduce cutaneous complications and length of hospitalization.

Because of their low oral bioavailabilities and short half-lives, it may be more feasible to administer narcotic analgesics via the skin. However, this delivery method is limited by the low permeability of the stratum corneum (SC). The aim of this study was to enhance the transdermal delivery of three narcotic drugs, including morphine, nalbuphine, and buprenorphine, with an erbium:yttrium-aluminum-garnet (Er:YAG) laser pretreatment. In an in vitro pig skin permeation experiment, Er:YAG laser pretreatment of the skin produced a 10~35-fold enhancement in drug permeation that was dependent on the laser fluence and the narcotic analgesic used. The permeation of morphine and nalbuphine showed higher enhancement with Er:YAG laser treatment as compared to that of buprenorphine. This may have been due to the higher lipophilicity and molecular mass of buprenorphine than the other two narcotic drugs. A photomechanical wave was generated by filtering laser radiation through a polystyrene target. The experimental results showed that a single photomechanical wave was sufficient to enhance morphine permeation by sevenfold. This enhancement was significantly lower than that produced by direct laser irradiation, indicating the predominant mechanism of SC ablation by the Er:YAG laser for transdermal drug delivery.

High-dose buprenorphine (HDB) treatment began in France in 1996 according to relatively unrestricted prescription rules. Continued heroin injection by patients on HDB maintenance treatment and even HDB injection remain underestimated and may lead to a variety of infectious diseases.. Description of infectious complications occurring in patients receiving HDB maintenance treatment.. Retrospective study of drug addicts receiving HDB maintenance treatment, injecting (or highly suspected of injecting) it, and hospitalized for infections (other than HIV or viral hepatitis) in the department of infectious and tropical diseases in Nancy University Hospital. Data collection covered 1998 through 2003.. We identified 21 case reports, 9 concerning infectious endocarditis, 8 cutaneous abscesses, 2 osteoarticular infections, 1 meningitis and 1 Candida retinitis. The sex-ratio was of 1 woman for 2 men, and the patients' mean age was 29.8 years. Globally 13 patients had systemic infections. Nine patients admitted having injected HDB (and no other drugs) (including the case of Candida retinitis), while in the other 12 cases, the patients continued injecting heroin as well. The role of misused HDB was strongly suspected in those 12 infections, but was not clearly confirmed. All patients recovered from the infections. The long-term psychosocial outcome remains unknown.. The cases analyzed illustrate the dual reality that HDB is often ineffective as a maintenance treatment, since some patients continue to inject heroin, and that its misuse can have infectious consequences. The results of HDB maintenance treatment substitution are mixed. The individual benefit/risk ratio must be improved. Networking is crucial, notably between physician and pharmacist, and the monitoring system must be reinforced.
