Association of Chronic Urticaria With Hepatitis C Infection In Female Patients Visiting Tertiary Care Hospital In Pakistan

Objective: To evaluate association of chronic urticaria with hepatitis C infection in female patients. Study Design: comparative cross-sectional study. Place and Duration of Study: Fauji Foundation Hospital Rawalpindi. One-year duration (Jan 2020-Jan 2021). Methodology: One Hundred female patients (group 1) of age 60 years or less with chronic urticaria were enrolled in this study. Patients with chronic liver disease or signs of hepatic decompensation were excluded. Equal number of age and gender matched patients not having urticarial symptoms were selected as group 2. Anti-Hepatitis C Virus Antibody (HCV ab) was evaluated by Enzyme linked immunosorbent assay (ELISA). Disease severity was calculated by Urticaria activity score 7(UAS 7). Association of HCV infection with chronic urticaria and its severity was analyzed by applying appropriate statistical tests. Results: Anti HCV antibody positivity frequency was 14/100(14%) in group 1 and 4/100(4%) in group 2 (p value: 0.013; significant). Mean ages in group 1 and 2 were 39.88+1.38 and 38.79+1.35 years respectively (p value: 0.57; insignificant). Mean UAS 7 calculated in the HCV negative Urticaria cases was 6.73+2.94 while it was significantly higher in HCV positive group i.e. 8.78+6.459 (p value 0.01). Frequency of HCV positivity in patients with well controlled urticaria and mild urticaria was 6/59(10.0%) and 5/36(13.8%) respectively while in moderate urticaria was 3/5(60%) which was significantly higher (p value 0.04). Conclusion: There is a significant association of chronic urticaria with anti HCV antibody positivity. HCV positive patients have more severe disease as compared to HCV negative patients.

Frequency of Scabies in Pediatric Allergy Clinic and Evaluation of Demographic Characteristics of Affected Patients

Objective: There has been an increase in the number of cases as pediatricians mistakenly refer scabies to an allergy clinic, misdiagnosing it as allergic illnesses, particularly atopic dermatitis (AD), because of the presence of symptoms such as itching and eczematous lesions. The objective of our study was to examine the prevalence of scabies in children who were referred to the pediatric allergy clinic after being misdiagnosed with AD. We also aimed to determine the clinical and demographic distinctions between individuals with AD and scabies. Methods: The files of 610 patients those referred to Sakarya Training and Research Hospital Pediatric Allergy Clinics between February-December 2022 with complaints of 'itching and rash' were documented retrospectively. Cases of acute urticaria, chronic urticaria, mastocytosis, insect bite, maculopapular rash with viral infection, drug-induced reactions were excluded. Patients whose final diagnosis was AD and who were diagnosed with 'definite scabies' were included in the study. Results: A total of 404 patients were included in the study. The rate of definite diagnosis of scabies was 18.5% (n:75/404). The median age at presentation was 19 months (IQR 8-51) in patients diagnosed with AD and 53 months (IQR 17-117) in patients diagnosed with scabies (p<0.005). The median time from symptom onset to diagnosis was seven months (IQR 2.5-24) in the AD group and two months (IQR 1-4) in the scabies group (p<0.005). Only 20% (n:15/75) of patients with scabies had family history, 16% of patients (n:12/75) had received one or more treatments before. Pruritis was present in only 72% (54/75) of children. Hospitalization rate was 0.05% (n:4/75). Conclusion: We recommend that scabies should be considered as a potential diagnosis for patients who visit to any clinic with symptoms of itching and a skin rash. Timely identification and medical intervention for scabies in children is crucial in order to minimize the spread of the disease throughout the community and prevent potential complications.

A comparison of mast cells in skin biopsies of cutaneous mastocytosis with other inflammatory dermatoses: A study of 33 cases.

Histopathologic criteria for diagnosis of cutaneous mastocytosis include 20 mast cells per high-power field or clusters of 15 mast cells. We aimed to determine the specificity of these criteria for cutaneous mastocytosis in comparison with inflammatory disorders of mast cell activation. Twenty-six cases of spongiotic dermatitis or urticaria were identified from 2021 to 2022. Recuts were stained with mast cell tryptase and slides were reviewed for the presence of 20 mast cells per high-power field and for clusters of 15 mast cells. In addition, seven cases of mastocytosis were reviewed for the same criteria. Twelve of 26 cases (46.1%) of spongiotic dermatitis/urticaria had at least 20 mast cells per high-power field. Three of 26 cases (11.5%) of spongiotic dermatitis/urticaria had a cluster of 15 mast cells. Six of seven cases (85.7%) of mastocytosis had at least 20 mast cells per high-power field; four of seven cases (57.1%) of mastocytosis had a cluster of 15 mast cells. In our study, the finding of 20 mast cells per high-power field was nonspecific as a single criterion for cutaneous mastocytosis. The finding of clusters of 15 mast cells was more specific but not sensitive.

Efficacy and safety of combinations of H1 antihistamines in the treatment of urticaria: A scoping review.

The efficacy and safety of combining H1 antihistamines (AHs) for treating urticaria are currently unclear. This scoping review aims to provide a comprehensive overview of the evidence regarding the efficacy and safety of H1 AH combinations in the management of urticaria up to May 2023. The search encompassed databases such as PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, and the China Biological Medicine Database. The inclusion criteria comprised randomised controlled trials (RCTs), non-randomised trials (NRTs), case reports, and case series focusing on urticaria treatment. Initially screening 12,887 studies, this review ultimately selected 109 studies involving 11,435 patients. These studies documented 43 different combination treatments across 11 types of urticaria. In comparison to monotherapy, combination therapy exhibited superior efficacy in 94 studies that reported treatment efficacy. Regarding adverse drug reactions (ADRs), 67 studies disclosed ADR incidences, with combination therapy showing lower ADR rates in 32 studies. Additionally, 7 studies reported similar ADR rates between combination therapy and monotherapy with AHs. Common ADRs included symptoms such as drowsiness, nausea, fatigue, dry mouth, dizziness, and headache, while less frequent side effects encompassed hypotension, otitis media, polyuria, rhinorrhoea, abnormal liver function, and rash. ADR rates ranged from 0% to 21% in the treatment group, and from 0.5% to 75% in the control group. Importantly, patients generally tolerated these ADRs well, with symptoms resolving upon discontinuation of treatment. The study's findings suggest that combining AHs leads to enhanced efficacy and reduced safety risks compared to monotherapy in the context of urticaria treatment. These results advocate for considering combination therapy as a viable option in clinical practice, especially for chronic urticaria cases. Nonetheless, caution is advised, and close monitoring for potential ADRs is crucial during treatment.

Global, regional, and national levels and trends in burden of urticaria: A systematic analysis for the Global Burden of Disease study 2019.

Urticaria places a significant burden on individuals and society due to its widespread nature. The aim of this study was to evaluate the burden of urticaria in different regions and nations by analysing data from the Global Burden of Disease study 2019 (GBD 2019), with the goal of providing information to health care policymakers. By utilising data from the GBD 2019 database, this study analysed metrics such as incidence, prevalence, disability-adjusted life years (DALYs), age-standardised rate (ASR), and estimated annual percentage changes (EAPC) globally and across 204 countries and regions. The data was further stratified by age, sex, and sociodemographic index (SDI). In 2019, global incidence cases, prevalence cases, and overall disease burden as measured by DALYs all increased. The distribution of the burden exhibited marked geographical heterogeneity. At the regional level, the burden is highest in Central and Eastern Europe and Central Asia, with the strongest growth in South Asia, compared with a decline in the high-income Asia Pacific. At the country level, Nepal reports the highest burden of urticaria, while Portugal has the lowest. Gender and age analyses showed that the burden of urticaria is higher in females than in males, with urticaria cases declining with age, especially in children, and picking up among the elderly. The study also finds a correlation between the burden of urticaria and the SDI, with the central part of the SDI showing a consistent increasing trend. This study found that the global burden of urticaria has risen from 1990 to 2019. Factors like geographic location, gender, and SDI influenced the urticaria burden. Overall, these results offer a resource to guide public health strategies seeking to reduce the burden of urticaria.

Red Meat Hypersensitivity and Probable Alpha-Gal Syndrome: Prevalence Among Adolescents.

It is unknown whether late adolescents represent a particular risk group for the development of red meat hypersensitivity (RMH) and alpha-gal syndrome (AGS). This age group's physiological changes and eating habits could play a determining role. This study aimed to estimate the self-reported prevalence of RMH and probable AGS among late adolescents. A cross-sectional study analyzed a sample of 1992 Mexican adolescents between 15 and 18 years of age. The data were obtained with a previously validated questionnaire that asked about the clinical manifestations related to red meat intake. Confidence intervals at 95% (95% CI) were estimated for proportions. In total, there were 19 adolescents with RMH, a prevalence of 1.0% (95% CI: 0.6-1.5%). The main red meats related to symptoms were pork (89.5%), beef (21.1%), lamb (10.5%), and mutton (5.1%). The most frequent manifestations of RMH were gastrointestinal (73.7%), respiratory (63.2%), and cutaneous (63.2%). Once the symptoms were grouped, there were two cases of urticaria (2/19, 10.5%) and six cases with probable anaphylaxis (6/19, 31.6%). Finally, three adolescents were considered probable cases of AGS, which represents a prevalence of 0.15% (95% CI: 0.1-0.4%). Although the prevalence of RMH in late adolescents is low, early detection is justified because approximately one-third present with severe symptoms.

Urticaria in infants: A single-institution retrospective study.

Urticaria in infants can cause significant anxiety in parents, especially if a trigger cannot be identified. In a retrospective study of 246 infants seen for urticaria of unknown etiology at Boston Children's Hospital, 88.2% had resolution of urticaria within 6 weeks. The etiology of urticaria was ultimately established in 62.6% (72/115) of acute urticaria and 12.5% (2/16) of chronic urticaria cases with follow-up data. Pediatric healthcare providers can counsel families that while etiology of urticaria is never determined in over 40% of infants, symptoms are most likely to resolve spontaneously.

Urticaria Revealing an Hepatitis B Infection: About a Case at the Dermatology-Venereology Unit of the National University Hospital Center (NUHC) of Bangui

Urticaria is a common syndrom which is manifested by pruritic edematous erythematous plaques. These plaques have no predilection site. They can migrate during the evolution of urticaria. Their second particularity is their fleeting character for they disapear after few hours without treatment. Urticaria has been associated with psychological, allergic and infectious factors. Among incriminated infections, hepatitis viruses have been cited. We are reporting a case of urticaria revealing an anicteric hepatitis B infection.

From pharmacovigilance to pharmaceutical care: About a case of urticaria and angioedema

The concept of “pharmaceutical care” was developed in 2017 in Algeria to globally define the practice of clinical pharmacy. The EHU Oran pharmacovigilance department has thus benefited from the integration of pharmaceutical care to improve drug management. We report a clinical case of urticaria and angioedema in a 22-year-old female patient in a context of polymedication with non-steroidal anti-inflammatory drugs (NSAIDs). A notification was sent to the pharmacovigilance department to estimate the causality assessment. The aim of our article is to illustrate the integration of pharmaceutical care system with the pharmacovigilance, based on this clinical case.

Role of patient-reported outcome measures in the management of chronic urticaria and angioedema

Due to the lack of reliable biomarkers, patient-reported outcome measures (PROMs) have a crucial role in assessing and monitoring the progression of chronic urticaria (CU) and angioedema (AE). PROMs are described as “any report coming directly from subjects without interpretation of the physician or others about how they function overall or feel in relation to a condition and its therapy.” There are four urticaria-specific PROMs, namely, urticaria activity score (UAS), urticaria control test (UCT), CU quality of life (QoL) questionnaire, and urticaria severity score. UAS7 is the most widely used, simple, and validated scoring system to estimate disease activity in chronic spontaneous urticaria cases. UCT on the other hand is a retrospective assessment of the current control of the disease after initiation of the treatment. The current EAACI/GA2LEN/EuroGuiDerm/APAAACI international urticaria guidelines suggest the use of UCT for stepping up or stepping down in the treatment of urticaria. Similarly, the severity and control of AE can be assessed by two PROMs, namely, AE activity score and AE QoL questionnaire.

Genome-wide meta-analysis implicates variation affecting mast cell biology in urticaria

Urticaria is characterized by inappropriate mast cell degranulation leading to the development of wheals and/or angioedema. Twin and family studies indicate that there is a substantial heritable component to urticaria risk. Our aim was to identify genomic loci at which common genetic variation influences urticaria susceptibility. Genome-wide association studies of urticaria (including all subtypes) from 3 European cohorts (UK Biobank, FinnGen, and the Trøndelag Health Study [HUNT]) were combined through statistical meta-analysis (14,306 urticaria cases and 650,664 controls). Cases were identified via electronic health care records from primary and/or secondary care. To identify putative causal variants and genes, statistical fine-mapping, colocalization, and interrogation of publicly available single-cell transcriptome sequencing resources were performed. Genome-wide significant associations (P< 5×10-8) were identified at 6 independent loci. These included 2 previously reported association signals at 1q44 and the human leucocyte antigen region on chromosome 6. Genes with expected or established roles in mast cell biology were associated with the 4 other genome-wide association signals (GCSAML, FCER1A, TPSAB1, and CBLB). Colocalization of association signals consistent with the presence of shared causal variants was observed between urticaria susceptibility and increased expression of GCSAML (posterior probability of colocalization [PPcoloc]= 0.89) and FCER1A (PPcoloc= 0.91) in skin. Common genetic variation influencing the risk of developing urticaria was identified at 6 genomic loci. The relationship between genes with roles in mast cell biology and several association signals implicates genetic variability of specific components of mast cell function in the development of urticaria.

Giardiasis as a cause of acute urticaria (case study)

The article describes a clinical case of acute urticaria against the background of a parasitic infection in a child who was examined and treated in the pediatric department of the State Budgetary Institution of Healthcare of JSC "Childrens Hospital No. 1". The description of this clinical case shows the ambiguity of the search for verification of the diagnosis.

Treatment of Urticaria caused by severe cryptosporidiosis in a 17-month-old child – a case report

BackgroundCryptosporidium is an intracellular protozoan that causes gastrointestinal symptoms in humans and animals. In immunocompromised patients and children under 5 years of age, the infection is severe and can be life-threatening due to severe diarrhea.Case presentationWe report a case of urticaria associated with Cryptosporidium in a 17-month-old female Iranian child. The patient had moderate diarrhea (> 3 loose, watery stools but not more than 10 diarrhea stools in a day), weight loss, and acute urticarial (rash clears completely within 6 weeks). Since the child’s father worked in livestock farming, the parasite may have been transferred from the cow or calve to the house and the child. Several Cryptosporidium oocysts were detected in the modified acid-fast staining of the child’s stool sample. The patient was successfully treated with nitazoxanide (100 mg twice daily) and became negative for parasites three days after treatment and one week after discharge from the hospital. The child was observed to produce < 3 loose stools in the previous 24 h after 1-week post-treatment and after 6 months of follow-up.ConclusionA number of parasites are associated with urticaria, but to our knowledge, there is no information on Cryptosporidium-induced urticaria. Therefore, our result may be evidence for the role of this parasite in the development of urticaria if other causes such as food allergies, autoimmune diseases and etc. don’t role in urticaria.

Self-Reported Allergic Occupational Contact Dermatitis among Dental Healthcare Professionals in United Arab Emirates -A Cross Sectional Study.

In dentistry, occupational contact dermatitis may affect dental professionals along with technicians, nurses, and patients. Changes to dental practice in recent years have altered the reported frequencies of allergens causing contact dermatitis in both dental professionals and dental patients. In the current cross-sectional study, we used a structured questionnaire and clinical examinations to examine the prevalence of self-reported hand eczema among United Arab Emirates (UAE). The relationship between subjective skin discomfort and latex, composite/bonding, or other dental materials also was explored. A structured questionnaire was designed to analyze the prevalence of skin conditions among dental professionals and study its implication in gender, occupation, and age groups. The questionnaire included information about skin symptoms, atopy, occupational experience, and other background factors like respiratory symptoms, work history and methods, and exposure at work. It was distributed to 550 randomly selected dental healthcare professionals. Out of 550 dental healthcare workers contacted, 434 responded giving a response rate of 79%. The prevalence of dry and rough skin on the hands was highest (45%). There was a total of 29 cases of allergic contact dermatitis, 15 cases of contact urticaria, 12 cases of irritating contact dermatitis, and 1 incidence of onychomycosis among the 100 dental healthcare professionals who reported having dermatitis on their hands, forearms, or faces due to their daily dental chores. Rubber chemicals and natural rubber latex (NRL) in protective gloves used by dentists, as well as dental-restorative plastic materials (methylacrylates), were the most common causes of allergy. Dry skin and hand eczema were more common among dental healthcare professionals. Plastic gloves or NRL gloves with a low protein content are recommended for dental work. Skin exposure to methylacrylates or latex should be avoided.

Cold-induced urticaria after black ant bite anaphylaxis.

Acquired cold-induced urticaria is a form of physical urticaria that is usually spontaneous. However, reports have shown that bees, wasps, or jellyfish stings can trigger it. We report the first case of cold-induced urticaria following black ant bite-induced anaphylaxis. A 41-year-old lady with no chronic illness with a known black ant bite allergy history. Three years ago, she sustained a black ant bite that required an emergency room visit to treat anaphylaxis. A few days later, she developed attacks of generalized hives on exposure to cold air and objects. She was started on desloratadine tablets which controlled her symptoms. The patient was given EpiPen and instructed to avoid black ants' approach and exposure to cold. She was then followed up in our clinic. Acquired cold-induced urticaria is a form of physical chronic inducible urticaria. Physical urticarias account for 25 % of chronic urticarias. The patient can have wheals, angioedema, or both in response to the cold exposure. Symptoms can be mild or severe, limiting the patient's quality of life. Acquired cold urticaria is idiopathic; however, cases have been reported after different triggers, such as insect stings (bees, wasps, and jellyfish). The black Samsum ant is a recognized trigger of allergic reactions in Qatar and the Gulf region. In a study done in Qatar, 23.5% of anaphylaxis cases were due to black ant stings. There are no validated or standardized skin tests or immunotherapy for the black Samsum ant, which necessitates physicians to be careful in assessing such patients and focus on taking a detailed history. The limitation of testing and immune therapy makes history the tool for diagnosis, and avoidance is the mainstay of treatment.

Hives and Butterflies: A Curious Case of Urticaria

Hives and Butterflies: A Curious Case of Urticaria

Chronic Urticaria Caused by Five Types of Borrelia: Case Study

Background: Lyme disease (Lyme disease-LD) is a disease of humans and animals that is transmitted by hematophagous insects, especially ticks. The causative agent is the spirochete Borrelia burgdorferi, a bacterium with a complex structure and a slow biorhythm, which has the ability to coat the host's organism with mucus - create a biofilm - or turn into a cyst, and the host does not recognize it and does not create antibodies. This is the reason why, in 10-60% of cases, Borrelia tests are negative, even though it is present. The diagnosis of LD is made clinically, and it is confirmed serologically and microbiologically by isolation and/or detection of the causative agent by the PCR method from tissue samples and body fluids. Lyme disease stage II and III is called „the great imitator“ because its symptoms resemble those of other diseases, so diagnostic errors are often made. Objective: In this article we presented a case of stubborn urticaria in a 28-year-old saleswoman. Case presentation: Mother of two children, who was ruled out by clinical examination for autoimmune diseases and allergies to available allergens. We subsequently confirmed the diagnosis of chronic borreliosis, caused by five types of borrelia, serologically, after advanced intermittent antibiotic therapy, and after acquired food intolerance was discovered. In the available literature, we did not find information that chronic generalized urticaria was caused by Borrelia in combination with food intolerance. Conclusion: The presented case of a patient with chronic urticaria indicates that similar cases with urticaria, as well as all skin changes with intermittent walking symptomatology, should: Undergo clinical treatment, rule out immunological diseases and drug allergies, then test for Borrelia (ELISA+ immunoblot with Borrelia protein sequences!). Take into account the duration of the disease, the possibility of the disappearance of antibodies created in early childhood or a false-negative finding of antibodies, and in case of a negative finding, do not give up ex-yuvantibus therapy.

Unraveling the Complex Nexus of Chronic Spontaneous Urticaria: Immunological, Infectious and Psychosomatic Dimensions

Chronic Spontaneous Urticaria (CSU) is a complex dermatologic allergic condition characterized by unknown origins, frequent relapses, and resistance to therapy, contributing to a substantial psychosocial burden. Stressful experiences appear to coincide with CSU onset and exacerbation, suggesting a psychosomatic element within a psychoneuroimmunological framework. The condition significantly impairs patients’ quality of life, disrupting daily activities and exhibiting a high prevalence of psychiatric comorbidities. Recent theories propose autoantibodies activating mast cells as a potential key factor in CSU development. Psychological stress is considered both a trigger for CSU onset and a factor influencing the disease course and therapy effectiveness. Although the skin’s response mechanisms to psychological stress are not fully understood, inflammatory mediators, neuropeptides, and neurotransmitters are believed to play a role. Chronic Spontaneous Urticaria (CSU) is estimated to impact 0.5–1% of the global population at any given time, making up approximately two-thirds of all Chronic Urticaria (CU) cases. Among individuals with CSU/CIU, it is suggested that 33–67% experience both itchy welts and deeper skin swelling, while 29–65% solely have itchy welts, and 1–13% exclusively experience deeper skin swelling. Despite extensive research on the clinical aspects and origin of CSU/CIU in the last decade, the comprehensive understanding of the humanistic and economic implications of CSU/CIU remains unclear, especially for those with an inadequate response to initial treatment strategies. Research indicates that infections act as a facilitating factor for CSU initiation and perpetuation, with stress potentially necessary for the expression of the CSU phenotype. Detection and treatment of hidden infections have shown improvements in CSU patients, reinforcing the association between infections and CSU. A comprehensive, multidisciplinary approach that considers biological, psychological, and social aspects is emphasized for effective urticaria treatment. Current research underscores the significant psychological impact of CSU, particularly for individuals with more severe forms or those diagnosed with chronic autoimmune urticarial.
