Mucocutaneous Manifestations in Kidney Transplant Patients: Risk Factors.

Introduction Mucocutaneous complications in kidney transplant patients are due to drug toxicity or immunosuppression. The main objective of our study was to determine the risk factors associated with their occurrence. Methods We conducted a prospective analytical study (January 2020- June 2021) including kidney transplant patients seen at the Nephrology Department.We described the characteristics of the patients who presented mucocutaneous complications and then compared them to those who didn't to deduce the risk factors.Statistical analysis was performed using SPSS 20.0 (p<0.05). Results Of the 86 patients recruited, thirty patients had mucocutaneous complications. The mean age was 42.73, with a male predominance (73%). Ten kidney transplants were performed from a living-related donor. All the patients received corticosteroids, Mycophenolate Mofetil, and the Calcineurin Inhibitor: Tacrolimus (76.7%) or Ciclosporin (23.3%). Induction was performed with Thymoglobulin (n=20) or Basiliximab (n=10). Mucocutaneous complications were dominated by infectious manifestations (53.4%): eight cases of fungal infections; six cases of viral infections: warts (n=3), herpes labialis (n=2), intercostal herpes zoster (n=1), and two cases of bacterial infections: atypical mycobacteria and boils. Inflammatory complications (36.6%) included acne (n=4), urticaria (n=3), rosacea (n=1), simple maculopapular exanthema (n=1), aphthous lesion (n=1), and black hairy tongue (n=1). Actinic keratosis, skin xerosis, and bruises were found in one patient respectively. The evolution with a symptomatic treatment was good in all the patients.After statistical analysis, the factors significantly associated with the occurrence of mucocutaneous complications were advanced age, male gender, anemia, HLA non-identical donor, as well as the use of Tacrolimus or Thymoglobulin. Conclusion Infectious mucocutaneous complications are the most common dermatological manifestations among renal transplant recipients. Their occurrence is related to advanced age, male gender, anemia, HLA non-identical donor, and the use of Tacrolimus or Thymoglobulin.

Oral Complications of ICU Patients with COVID-19: Case-Series and Review of Two Hundred Ten Cases.

Background: The critically ill patients suffering from coronavirus disease (COVID-19) and admitted to the intensive care units (ICUs) are susceptible to a wide array of complications that can be life-threatening or impose them to long-term complications. The COVID-19 oral mucocutaneous complications require multidisciplinary management and research for their pathophysiological course and epidemiological significance; therefore, the objective of this study was to evaluate the prevalence and characteristics of the critically ill COVID-19 patients with oral complications. Methods: We described the clinical and microbiological characteristics of the critically ill COVID-19 patients in our ICU department (Banska Bystrica, Slovakia). In addition, we reviewed the current body of evidence in Ovid MEDLINE®, Embase, Cochrane Library, and Google Scholar for the oral mucocutaneous complications of ICU patients with COVID-19. Results: Three out of nine critically ill patients (33.3%) in our ICU department presented with oral complications including haemorrhagic ulcers and necrotic ulcers affecting the lips and tongue. The microbiological assessment revealed the presence of opportunistic pathogens, confirming the possibility of co-infection. On reviewing the current literature, two hundred ten critically ill patients were reported to have oral complications due to their stay in the ICU setting. Perioral pressure ulcers were the most common complication, followed by oral candidiasis, herpetic and haemorrhagic ulcers, and acute onset macroglossia. The prolonged prone positioning and mechanical ventilation devices were the primary risk factors for those oral complications, in addition to the immunosuppressive drugs. Conclusions: The multidisciplinary approach is strongly advocated for monitoring and management of COVID-19 patients, thus implying that dermatology and oral healthcare specialists and nurses should be integrated within the ICU teams.

Mucocutaneous complications in pediatric patients with liver transplantation

Background Liver transplant recipients can develop mucocutaneous lesions and the severity of these lesions can vary from benign to life-threatening conditions. The aim of this study was to investigate the frequency and clinical features of mucocutaneous complications after liver transplantation (LT) in pediatric patients. Methods Retrospectively, children who underwent LT and were detected with skin and mucosa lesions while being followed up in our Pediatric Gastroenterology outpatient clinic between June 2005 and July 2020 were evaluated. Age, gender, primary diagnosis, graft type, immunosuppression history and post-transplantation mucocutaneous complications were recorded from the patients’ file. Results Mucocutaneous lesions were observed in 16 (9 girls, 7 boys) of 37 patients after LT. Mean transplantation age ± SD was 1.96 ± 2.03 years and a mean follow-up period was 7.31 ± 2.69 years. The lesions due to viral infections were the most common dermatologic findings (n=7, 20.5%), followed by soft tissue infection (n=6), xerosis (n=5), urticaria (n=3), eczema (n=2), fissured tongue (n=3), acne vulgaris (n=3), tinea (n=2), alopecia areata (n=1), oral aphthae (n=1) and leukocytoclastic vasculitis (n=1). No premalignant or malignant lesion was detected in any patient. Conclusion Studies about mucocutaneous complications are limited in children after LT and these lesions are often caused by infections associated with the side effects of immunosuppressive treatment. Accordingly, a carefully dermatological examination should be performed during the follow-up of patients undergoing LT.

Immune Thrombocytopenic Purpura in Patients with COVID-19.

We described three COVID-19-infected patients with profound immune thrombocytopenia causing haemorrhagic mucocutaneous complications. We conclude that an immune mechanism was responsible as common causes were excluded. Since corticoids were considered harmful in the circumstances, the patients were successfully treated with intravenous immunoglobulins without later relapse.LEARNING POINTSThe severity of haemorrhagic syndrome is not correlated with the severity of COVID-19 infection.Thrombocytopenia in mild COVID-19 infection seems to have an autoimmune mechanism.Intravenous immunoglobulins (1 g/kg) should be the first line of treatment.

Toxic Epidermal Necrolysis and Steven-Johnson Syndrome: A Comprehensive Review.

Significance: Toxic epidermal necrolysis (TEN) and Steven-Johnson syndrome (SJS) are potentially fatal acute mucocutaneous vesiculobullous disorders. Evidence to date suggests that outcomes for patients with both TEN and SJS are largely dependent on stopping the causative agent, followed by supportive care and appropriate wound management in a specialized burns unit. These are life-threatening conditions characterized by widespread full-thickness cutaneous and mucosal necrosis. This article outlines the approach to holistic management of such patients, in a specialized unit, highlighting various practical aspects of wound care to prevent complications such as infection, mucosal and adhesions, and ocular scaring. Recent Advances: There is improved understanding of pain and morbidity with regard to the type and frequency of dressing changes. More modern dressings, such as nanocrystalline, are currently favored as they may be kept in situ for longer periods. The most recent evidence on systemic agents, such as corticosteroids and cyclosporine, and novel treatments, are also discussed. Critical Issues: Following cessation of the culprit trigger, management in a specialized burns unit is the most important management step. It is now understood that a multidisciplinary team is essential in the care of these patients. Following admission of such patients, dermatology, ear, nose, and throat surgery, ophthalmology, urology, colorectal surgery, and gynecology should all be consulted to prevent disease sequelae. Future Directions: Looking forward, research is aimed at achieving prospective data on the efficacy of systemic immunomodulating agents and dressing types. Tertiary centers with burns units should develop policies for such patients to ensure that the relevant teams are consulted promptly to avoid mucocutaneous complications.

Mucocutaneous Features of Zika-a Review.

We review the range of dermatological signs seen in Zika infection and the possible relationship between the rash and viremia. We also hoped to explore the utility of mucocutaneous manifestations in narrowing the differential diagnosis from other similar flaviviruses. Clinical manifestations of Zika infection share many similarities with other mosquito-borne viruses such as dengue. These include non-specific symptoms such as a fever, rash, arthralgia, myalgia, and conjunctivitis. The morphology of the rash in Zika infection is not very specific and commonly described as maculopapular and centrifugal that usually extends to become diffuse. We reviewed 123 publications, encompassing a total of 368 Zika cases. One hundred seven cases with rash had sufficient data for detailed analysis. 8.4% of cases with rash had hemorrhagic manifestations such as palatal petechiae and bleeding ulcers. Only 20 reported cases were tested for viremia during presence of rash, and 70.6% of these cases were positive. While mucocutaneous complications are common in Zika infection, more research is necessary to determine the impact of rash on diagnosis, prognosis, and transmissibility in Zika infection.

Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis in the Pediatric Population

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe dermatologic reactions with mucocutaneous involvement that carry elevated mortality rates. They differ along a spectrum of severity based upon body surface area affected. These conditions, usually caused by a drug or infection, are believed to result from cell-mediated and often drug-specific cytotoxic reactions against keratinocytes, leading to widespread dermal-epidermal detachment. Studies attempting to identify potential curative therapies such as intravenous immune globulin (IVIG) and corticosteroids remain inconclusive. However, improved outcomes have been demonstrated by early withdrawal of offending medications, early transfer to an intensive care unit or burn unit, and aggressive supportive care. Due to the rare incidence of SJS and TEN, its recurrence among survivors hints at future vulnerability for these patients, and notorious offending medications should thus be avoided. This clinical review will highlight the diagnostic and therapeutic challenges posed by SJS and TEN, while emphasizing the need to maintain them high on the emergency medicine physician's differential. The review will also detail the supportive measures to take for preventing the rapid progression of mucocutaneous complications and subsequent sepsis-related mortality.

Analysis of Radiomodulatory Effect of Low-Level Laser Irradiation by Clonogenic Survival Assay.

The aim of this study was to investigate the radiomoulatory effects of low-level laser irradiation (LLLI) in normal and cancer cells exposed to ionizing X-ray radiation on clonogenic survival assay. LLLI does have radioprotective effects on normal tissue. LLLI can reduce the incidence of mucocutaneous complications of ionizing radiation. Few in vitro studies reported adaptive responses for LLLI to ionizing radiation in normal and cancer cells, particularly with respect to clonogenic cell survival assay. Normal NIH 3T3 cells and cancer HeLa cells were irradiated with 685 and 830 nm LLLI at different energy densities prior to ionizing X-ray radiation. The survival fraction was determined after ionizing radiation (0, 2, 4, and 6 Gy). The values of the linear (α) and quadratic (β) parameters were calculated based on the clonogenic survival curves. Clonogenic radiation survival assay showed that the application of LLLI at 685 nm prior to ionizing radiation could significantly inhibit clonogenic growth of HeLa cells compared with unirradiated HeLa cells. LLLI could also significantly increase the α parameter of the linear quadratic (LQ) model. In contrast, application of LLLI at 830 nm could significantly protect NIH 3T3 cells against radiation and decreased α parameter. This study suggests that various physical parameters of LLLI can be diverse adaptive responses to ionizing radiation on normal and cancer cells.

Severe Drug Eruption in Guinea Conakry

Severe drug reactions are defined as mucocutaneous complications secondary to systemic admin- istration of drugs likely to be life threatening. Our work was designed to determine the evolutio- nary epidemiological and etiological characteristics of severe drug reactions to the Department of Dermatology Venereology, at Donka Teaching Hospital. A prospective descriptive study of all cases of severe drug reactions received at the Department of Dermatology Venereology of the Donka Teaching Hospital was conducted over a period of two years, from June 2009 to May 31, 2011. We identified 22 Stevens-Johnson syndrome, 13 Toxic Epidermal Necrolysis, 1 Stevens-Johnson syn- drome Border Toxic Epidermal Necrolysis, 1 Drug Rash with Eosinophilia and Systemic Symptoms and 2 Acute generalized exanthematous pustulosis among 481 hospitalized patients, of whom 50 had consulted for drug reactions, that is to say, a frequence of 10.40%. The Stevens-Johnson syn- drome accounted for 44%, the Stevens-Johnson syndrome Border Toxic Epidermal Necrolysis 2%, Toxic Epidermal Necrolysis 26%, Drug Rash with Eosinophilia and Systemic Symptoms 2% and Acute generalized exanthematous pustulosis 4% of drug reaction. The female sex was predomi- nant (28 women vs. 11 men), that is to say 71.59% vs. 26.21 with a sex ratio of 2.55. The average age of our patients was 29.72 years; the range of ages 21 - 40 years was the most affected (51.28%) followed by 0 - 20 years (33.33%). The lethality rate was 9.09% (2/22) in the Stevens-Johnson syndrome and 53.85% (7/13) in the Toxic Epidermal Necrolysis. HIV infection was found in 17.95% (7/26) of our patients and 71.42% (5/7) of the deceased. The drug accountability was established in 79.48%; the most commonly implicated drugs in the Toxic Epidermal Necrolysis were sulfona- mides followed by ARVs (nevirapine) and anti TB (isoniazid); in the SJS sulfonamides followed by salts of quinine and anti TB, the only case of DRESS was due to quinine. No drug was found in 20.52% (8 cases). HIV infection remains a poor prognostic factor. Our study shows the scarcity of Drug Rash with Eosinophilia and Systemic Symptoms and Acute generalized exanthematous pustulosis in our service. * Corresponding author.

Mucocutaneous complications of smoking cessation therapies

Despite widespread knowledge of the morbidity and mortality associated with smoking, this addictive practice continues to be quite prevalent throughout the United States, as about one-fifth of the population smokes cigarettes. Because of the financial burden, and the significant psychosocial and health implications of smoking, many individuals are now attempting to quit, and often using some type of pharmacotherapy for assistance. Given that dermatologists will likely encounter patients using smoking cessation aids, it is important to be aware of their potential mucocutaneous adverse effects. We present a brief review of the dermatologic complications associated with smoking cessation therapies. Hopefully, this article will alsoremind dermatologists to encourage smoking cessation at every visit.

Clinical Evaluation of the European LeukemiaNet Criteria for Resistance/Intolerance to Hydroxyurea In Essential Thrombocythemia

AbstractAbstract 4086Definition of resistance/intolerance to hydroxyurea (HU) in essential thrombocythemia (ET) has been proposed by the European LeukemiaNet (ELN) however its clinical utilility has not been validated yet. We have retrospectively evaluated such criteria in 166 ET patients treated with HU for a median of 4.5 years. Response to HU treatment was categorized using the ELN criteria. The ELN definitions of resistance/intolerance to HU required the fulfillment of at least one of the following criteria: platelet count greater than 600 × 109/L after 3 months of at least 2 g/day of HU (2.5 g/day in patients with a body weight over 80 kg); platelet count greater than 400 × 109/L and leukocytes less than 2.5 × 109/L or hemoglobin (Hb) less than 100 g/L at any dose of HU; presence of leg ulcers or other unacceptable mucocutaneous manifestations at any dose of HU; HU-related fever. Survival and time-to-event curves were estimated using the Kaplan-Meier method.Variab les attaining a significant level at the univariate analysis were included in a Cox proportional hazards model. Overall, 134 patients achieved a complete clinicohematologic response (CR) and 25 a partial response. Thirty-three patients met at least one of the ELN criteria defining resistance (n=15) or intolerance (n=21) to HU. Fifteen cases developed anemia with thrombocytosis. Other definitions of resistance were less useful. When compared with the others, resistant patients were more likely to display hyperproliferative features at ET diagnosis, such as higher levels of leukocytes (p= 0.05), platelets (p=0.004) and serum LDH (p=0.02). Eleven patients developed leg ulcers leading to a permanent discontinuation of the drug in 8 cases. No distinctive clinical profile could be ascribed to patients exhibiting leg ulcers, with the exception of a high prevalence of cardiovascular risk factors. Other unacceptable mucocutaneous manifestations occurred in 9 patients. Hematologic and mucocutaneous complications were unrelated, with only two patients presenting both types of toxicities. With a median follow-up from ET diagnosis of 7 years (range: 0.5–23), 38 patients (23%) had died, resulting in a survival probability of 65% at 10 years from HU start. The risk of death from any cause was increased by 6.2-fold (95%CI: 2.3–16.7, P<0.001) in patients who met any of the ELN criteria of resistance to HU. Anemia was in all instances the first finding qualifying for resistance to HU, with the median subsequent survival of patients with anemia being only 2.4 years (range, 0.01–4.9). A remarkable incidence of myelofibrosis was observed in patients fulfilling the ELN criteria for resistance, since this complication was recorded in 7 of 15 such cases (p>0.001). In conclusion, the best discriminating ELN criterion of resistance to HU is based on the detection of anemia. Moreover, such criterion is particularly useful since it also identifies a subset of ET patients with a poor prognosis. Disclosures:No relevant conflicts of interest to declare.

Perioperative haemostatic management of Glanzmann thrombasthenia for abdominal surgery

Glanzmann thrombasthenia is a rare congenital platelet disorder characterized by spontaneous mucocutaneous bleeding and severe bleeding complications during major surgery. This report centres on the perioperative haemostatic management of a patient with Glanzmann thrombasthenia undergoing elective major abdominal surgery. The treatment regimen was based mainly on recombinant activated factor VII, fibrinogen, and factor XIII, reducing platelet transfusion to a minimum. No red blood cell transfusions were needed perioperatively. For haemostatic monitoring, routine laboratory tests were sufficient.

Ecthyma Gangrenosum Following Toxic Epidermal Necrolysis Syndrome in a 3-Year-Old Boy—a Survivable Series of Events

Toxic epidermal necrolysis syndrome (TENS) is a severe but rare skin reaction leading to epidermal desquamation of greater than 30% of the TBSA. It is most commonly precipitated by the administration of medication. Frequent complications of this syndrome include local wound infections, respiratory, mucocutaneous, and ocular complications. Ecthyma gangrenosum (EG) is a rare disease characterized by a milliary seeding of the cutaneous tissue with Gram-negative bacteria; it is most commonly seen in immunocompromised individuals. Here we report a 3-year-old boy who developed EG subsequent to TENS. Although he had a complicated and prolonged hospital course, he survived these series of events. To our knowledge, this is the first reported case of TENS/EG in the pediatric population, and the first report of survivability following these illnesses.

Clinical management of the complications of HIV infection

Patients with advancing HIV infection are subject to a broad range of complications that may challenge the primary care physician. The presence of more than one complication at a time is common. Selected, common complications are discussed, including a discussion of the approach to diagnosis and management. Areas covered include pulmonary, gastrointestinal, ocular, and mucocutaneous complications, as well as lymphadenopathy, the HIV wasting syndrome, and Kaposi's sarcoma.

Mucocutaneous complications of intraarterial 5-bromodeoxyuridine and radiation

5-Bromodeoxyuridine (BUDR), a halopyrimidine thymidine analogue, is incorporated into the DNA of dividing cells and causes photoradiosensitization. Twenty-five patients with malignant astrocytomas were treated with continuous intracarotid BUDR radiosensitization and radiotherapy for 8 1/2 weeks. Unique dose-limiting mucocutaneous complications were encountered. Ipsilateral facial dermatitis with epilation of eyebrows and eyelashes, ocular irritation, and bilateral nail dystrophy developed in all patients. Less common reactions included oral ulceration in six patients, body exanthem on the trunk in five, and atypical erythema multiforme major in one.

METHISAZONE THERAPY IN PEDIATRIC VACCINIA COMPLICATIONS

Methisazone 40 mg/kg/day was administered orally to six pediatric and one adult patient who contracted vesicular complications affecting the skin or mucocutaneous junctions 3 to 9 days after antismallpox vaccination, and to one elderly man with myeloid leukemia who developed vaccinia necrosum. Therapy was commenced 2 to 10 days after onset of complications and was administered for 3 days. All patients with skin or mucocutaneous complications showed dramatic clinical responses within one day after commencement of antiviral chemotherapy, and complete recovery occurred within one week. Clinical improvement was noted 4 days after therapy was begun in the case of vaccinia necrosum, and recovery occurred after 3 weeks.
