BestPractice Nordic proudly presents: In this magazine, we are happy to introduce our newly established dermatology advisory board. The doctors who have

taken on this job will act as sparring partners to the editorial desk on topics, studies, and newest research.

Our board members will ensure the high

quality of our publications and keep our readers up to date within the field.

All content published through BestPrac-

tice Nordic’s channels is made by clini-

cians, for clinicians within the field. We hope and encourage all of you to con-

tinue to contribute to the development

by asking questions and sharing your knowledge and research.

Kristina Ibler Medical doctor at Zealand University Hospital since 2007. Specialty: AD. Country: Denmark.

Being part of the clinical advisory board is unpaid, but makes a great difference,

not only by ensuring knowledge sharing between Nordic health professionals but

also by supporting our collaboration with Doctors Without Borders. Hence, last year

we were able to donate close to DKK 100,000 on behalf of all of our contributors.

We are looking forward to a great collabo­ ration with this new board of experts.

Pligtoplysninger/Forkortet produktresumé Olumiant® 2 mg og 4 mg filmovertrukne tabletter (baricitinib) Indikationsområde: Reumatoid artritis: Olumiant er indiceret til behandling af moderat til svær aktiv reumatoid artritis hos voksne patienter, der ikke har responderet tilstrækkeligt på eller ikke tåler et eller flere sygdomsmodificerende antireumatiske lægemidler (DMARDs). Olumiant kan anvendes som monoterapi eller i kombination med methotrexat. Atopisk dermatitis: Olumiant er indiceret til behandling af moderat til svær atopisk dermatitis hos voksne patienter, der er kandidater til systemtisk behandling. Dosering: Den anbefalede dosis af Olumiant er 4 mg én gang dagligt. En dosis på 2 mg én gang dagligt er passende til f.eks. patienter ≥ 75 år og kan være passende til patienter med kroniske eller tilbagevendende infektioner i anamnesen. En dosis på 2 mg én gang dagligt kan også overvejes til patienter, der har opnået vedvarende kontrol af sygdomsaktivitet med 4 mg én gang dagligt og er egnede til nedtrapning af dosis. Atopisk dermatitis: Olumiant kan anvendes med eller uden topikale kortikosteroider. Olumiants virkning kan øges, når det gives sammen med topikale kortikosteroider. Topikale calcineurin-hæmmere kan anvendes, men skal udelukkende forbeholdes følsomme områder, såsom ansigtet, halsen, intertriginøse- og genitale områder. Det bør overvejes at seponere behandlingen hos patienter, som ikke viser tegn på terapeutisk effekt efter 8 ugers behandling. Behandling bør ikke indledes hos patienter med absolut lymfocyttal (ALC) < 0,5 x 109 celler/l, absolut neutrofiltal (ANC) < 1 x 109 celler/l eller med hæmoglobin < 4,96 mmol/l. Behandling kan indledes, når værdierne er kommet op over disse grænser. Der henvises til produktresume for dosisjustering hos særlige populationer. Bivirkninger: Meget almindelig (≥1/10): Infektioner i øvre luftveje. Hyperkolesterolæmi. Almindelig (≥1/100 til <1/10): Herpes zoster. Herpes simplex. Gastroenteritis. Urinvejsinfektioner. Pneumoni. Trombocytose > 600 x 109 celler/l. Hovedpine. Kvalme. Abdominalsmerter. Alanin-aminotransferase (ALAT) ≥ 3 x øvre normal grænse (ULN). Udslæt. Akne. Forhøjet kreatinkinase >5 x ULN. Ikke almindelig (≥1/1.000 til <1/100): Neutropeni < 1 x 109 celler/l. Hypertriglyceridæmi. Divertikulitis. Aspartat-aminotransferase (ASAT) ≥ 3 x ULN. Hævelse i ansigtet. Urticaria. Lungeemboli. Dyb venetrombose. Vægtstigning. Kontraindikationer: Graviditet. Overfølsomhed over for det aktive stof eller over for et eller flere af hjælpestofferne. Særlige advarsler og forsigtighedsregler: Infektioner: Baricitinib er forbundet med en øget forekomst af infektioner, f.eks. infektioner i øvre luftveje. Risiciene og fordelene ved Olumiant-behandling skal derfor nøje overvejes forud for indledning af behandling hos patienter med aktive, kroniske eller tilbagevendende infektioner. Patienter bør screenes for tuberkulose (TB), før behandling med Olumiant indledes. Olumiant må ikke gives til patienter med aktiv TB. Viral reaktivering: I kliniske studier blev der rapporteret viral reaktivering (f.eks. herpes zoster, herpes simplex). Hvis en patient udvikler herpes zoster, bør Olumiant-behandlingen afbrydes midlertidigt, indtil episoden er gået over. Før opstart af behandling med Olumiant bør udføres screening for viral hepatitis i overensstemmelse med kliniske retningslinjer. Hvis hepatitis B virus (HBV-DNA) påvises, bør en specialist i leversygdomme konsulteres. Vaccination: Anvendelse af levende, svækkede vacciner under eller umiddelbart før behandling med Olumiant anbefales ikke. Før behandling med Olumiant påbegyndes, anbefales det, at patienterne bringes a jour med al immunisering i overensstemmelse med gældende retningslinjer for immunisering. Lipider:

10 Se annonce side 11.

Lipidparametre bør vurderes ca. 12 uger efter indledning af behandling med Olumiant, og herefter bør patienterne håndteres i overensstemmelse med internationale kliniske retningslinjer for hyperlipidæmi. Hematologiske anomalier: Behandlingen bør midlertidigt afbrydes ved lav ALC/ANC/hæmoglobin, henvisning til afsnittet “dosering”. Risikoen for lymfocytose er øget hos ældre patienter med reumatoid artritis. Sjældne tilfælde af lymfoproliferative tilstande er blevet rapporteret. Stigning i leveraminotransferaser: Der blev rapporteret dosisafhængige stigninger i ALAT og ASAT i blodet hos patienter, der blev behandlet med bacitinib. Hvis der observeres stigning i ALAT eller ASAT under den rutinemæssige kontrol af patienterne, og der er mistanke om lægemiddelinduceret leverskade, skal behandlingen med Olumiant afbrydes midlertidigt, indtil denne diagnose er udelukket. Malignitet: Immunmodulerende lægemidler kan øge risikoen for malign sygdom, herunder lymfom. De kliniske data er ikke tilstrækkelige til at vurdere den potentielle incidens af malign sygdom efter eksponering for baricitinib. Venøs tromboembolisme: Olumiant skal anvendes med forsigtighed til patienter med kendte risici for dyb venetrombose (DVT) og lungeemboli (PE). Behandling med Olumiant skal seponeres, hvis der opstår kliniske symptomer på DVT/PE, og patienten skal straks vurderes efterfulgt af en passende behandling. Overfølsomhed: Efter markedsføring er der rapporteret om tilfælde af lægemiddeloverfølsomhed forbundet med administration af baricitinib. Hvis der opstår en alvorlig allergisk eller anafylaktisk reaktion, skal behandling med baricitinib straks seponeres Divertikulitis: Der er rapporteret om tilfælde af divertikulitis og gastrointestinal perforation i kliniske studier og efter markedsføring. Baricitinib bør anvendes med forsigtighed hos patienter med divertikelsygdom og især hos patienter, der er i kronisk behandling med samtidige lægemidler, som er forbundet med øget risiko for divertikulitis: non-steroide anti-inflammatoriske lægemidler, kortikosteroider og opioider. Patienter, der har ny forekomst af abdominale tegn og symptomer, bør undersøges øjeblikkeligt med henblik på tidlig identifikation af divertikulitis eller gastrointestinal perforation. Fertilitet, graviditet og amning: Olumiant er kontraindiceret under graviditet. Fertile kvinder skal anvende sikker kontraception under behandlingen og i mindst 1 uge efter afsluttet behandling. Hvis en patient bliver gravid under behandling med Olumiant, skal kvinden og hendes partner informeres om den potentielle risiko for fosteret. Det vides ikke, om baricitinib/metabolitter udskilles i human mælk og Olumiant bør ikke anvendes under amning. Overdosering: Enkeltdoser på op til 40 mg og flere doser på op til 20 mg dagligt i 10 dage er blevet administreret i kliniske studier uden dosisbegrænsende toksicitet. Bivirkningerne var sammenlignelige med de bivirkninger, der blev set ved lavere doser, og der blev ikke identificeret nogen specifikke toksiske virkninger. I tilfælde af overdosering anbefales det, at patienten monitoreres for symptomer på bivirkninger. Lægemiddelformer: Filmovertrukne tabletter. Pakningsstørrelser og priser: 2 mg og 4 mg i pakninger af 28 tabletter.

Highlights from the 35th NCDV 2022 At NCDV 2022, Nordic and Baltic dermatologists came together to share the newest research and discuss hot topics.

Day 1: Psoriasis, AD, and chronic urticaria On Wednesday, April 20, the official programme started with the General assembly meeting of the Danish Dermatological Society (DDS). The chair position of DDS changed. Christian Vester­ gaard, Aarhus University Hospital is succeeded by Simon Francis Thomsen, Bispebjerg Hospital. Kristina Ibler, Bispebjerg Hospital becomes treasurer. The autumn meeting of DDS will be held in Aarhus on November 4-5 in a new and exciting format. All members are more than welcome to join.

Understanding and treating itch

Afternoon plenary sessions were split into par-

allel sessions on the two major chronic skin dis-

eases: Psoriasis and Atopic Dermatitis (AD). Each session had excellent speakers from across the

Nordic countries. The “itch session” held by Jes-

per Elberling, Gentofte Hospital, was quite an


enthusiasm for getting to grips with the patho-

fer significantly between patients with AD comsee in our clinics, as AD is often plastered by

secondary excoriations, which is almost never seen in patients suffering from urticaria. In AD,

itch is an inflammatory signal and part of the cascade of immunological reactions from the patient’s skin, which seeks to get rid of the sensation by initiating a mechanical action in the

form of scratch. The efferent sensation is led by the epidermal non-myelinated polymodal C-fi-

bres. The afferent mechanism is led by motor neurons that innovate and activate muscle contractions to achieve relief from itch. Itch is a

sensation that is rewarded with increased levels of oxytocin in the postsynaptic nerve endings of the CNS.

In addition, functional MRI studies of itch have

shown repeated activity in specific areas in the cerebral cortex. This can be imaged faster/ear-

lier than when the patient recognizes the visual

signs of dermatitis on their skin. Hence, itch in AD should be referred to as an inflammatory, and even more important, non-histaminerge itch. In contrast, in urticaria the itch sensation is a consequence of the rapid release of antihistamines

and prostaglandins from epidermal mast cells.

It is merely a consequence of the human innate immune response. In AD patients, JAK inhibitors

In the following parallel sessions, some of the

with EASI scores that are about to match the reported scores of PASI, for example EASI-50, EASI75 and EASI-90.

Addressing sexuality in dermatologic nursing care Sexuality is a basic human need. However, sexuality is not always included in the nursing assessment. Studies have uncovered barriers that give us insights into how we can improve our clinical practice and assess sexuality more frequently with our patients. How can we assess sexuality by increasing our knowledge? And how do we promote a positive attitude toward sexuality, combined with standardized use of the “Dermatology Life Quality Index”?

Interaction between hand eczema, HRQOL, and changed exposures for health care workers during the COVID-19 pandemic Studies on the prevalence of hand eczema during the pandemic found that more than one-third of health care workers reported hand eczema. But a 11-month follow-up study conducted during the COVID-19 pandemic with healthcare workers exposed to covid patients suggests that the links between changed exposures including hand hygiene procedures in patient care, and hand eczema are complex, and cannot be linked to a single factor.

CONCLUSION: Despite intense focus on hand hygiene during the pandemic, a slightly declining hand eczema prevalence was found in health care workers, but with a significant worsening of the hand eczema severity. We found a reduction in hand washings, but an increase in the use of ABHRs on wet skin and glove use, which was significantly associated with hand eczema. Our findings suggest that the interaction between hand eczema and changed exposures is quite complex and cannot be linked to a single factor. The prolonged use of gloves has previously

putation, even though aggressive therapies were initiated in the early stages. The data suggest that the

presence of PAD is a risk factor for a poor prognosis of PG. The simultaneous presence of PG and PAD seems to aggravate the prognosis, resulting in amputation in a significant proportion of our patients.

Thus, screening and diagnosis of PAD in the clinical setting of PG are essential for the prognosis. However, the rapid development of severe PAD in patients with initial standard TBI could suggest that the pres-

ence of PG could trigger the action of PAD. More stud-

ies are required to optimize the management of this

complex subgroup of PG patients and to investigate a possible causality effect between PAD and PG.

we feel the need to scratch. He has high hopes for the

Nail fold changes as a marker for psoriatic arthritis in psoriasis of the skin Patients with psoriatic arthritis may have decreased capillary density and blood flow as well as microbleeds in the nail fold. However, no single diagnostic capillary pattern could identify psoriatic arthritis. JØRGEN GULDBERG-MØLLER is a trained physiotherapist, doctor and PhD. He is employed as a ward doctor at Sjællands Universitetshospital in Køge as an ultrasound manager. He specializes in musculoskeletal diagnostic imaging and has a special interest in ultrasound. METTE MOGENSEN is a dermatologist. For more than 15 years, she has been working with the development of new advanced imaging diagnostics to detect skin diseases faster, easier, and more accurately by scanning the skin – in close collaboration with the Technical University of Denmark and leading international research groups.

Environmental factors and autoimmune diseases – a hypothesis

The use of pesticides and chemicals may give us new insights and predictions about the human intestinal virome’s handling of chronic diseases, for example, COVID19, using cytochrome polymorphism as a measurement. HENRIK NIELSEN is a rheumatologist and specialist in internal medicine and rheumatology. He holds several research and advisory positions in rheumatology. His professional interests cover environmental issues, and he works to promote aware-

ness of the negative impact of pesticide use on autoimmune diseases. MERETE ENGELHART is a specialist in internal medi­ cine and rheumatology at Department of Rheumatology, Gentofte and Center for Rheumatology and Spine Diseases, Rigshospitalet, Denmark. Her research is focused on connective tissue diseases, Raynaud Phenomenon, and connective tissue lung diseases.

For many years, the dialogue involving rheu-

matic diseases has focused on triggers involv-

ing environmental factors combined with viral components in the body; the triggers reactivat-

ing the sleeping virus, also called “the human intestinal virome.” But the interplay is poorly

understood between environmental factors

and possible viral components. The use of pesticides, chemicals, and other factors may give

us new insights into chronic diseases, especially if these diseases arise at an earlier living age resulting in new manifestations.

Organophosphate pesticides Organophosphate pesticides (OPs) are among the most widely used synthetic chemicals for the control of a variety of pests. Reactive oxygen species (ROS) caused by OPs might be involved in one of several toxicities of various pesticides. Previous studies have demonstrated that

the reactivation of Epstein-Barr virus (EBV), la-

tent in the human body (>95%), could involve

oxidative stress. In one study, OPs were able

to reactivate EBV through ROS accumulation.

Data showed that OP (chlorpyriphos, abbrevi-

ated as CPF) induces oxidative stress, accom-

immunity, increasing mortality by infectious

activity. Moreover, CPF exposure significantly These results suggest that OPs could contribute

to the reactivation of the EBV lytic cycle through ROS induction, a process that may play an im-

portant role in the development of EBV-­associated diseases as well as other rheumatic diseases.

EBV is a well-known factor in the mechanism

in systemic lupus erythematosus (SLE) , tak2

ing part in the crosstalk between the entero­

virus. But reactivation of EBV because of pes-

ticide exposure in SLE has not been reported. A postulate that rheumatoid arthritis could

be an occupational disease has been open

for discussion in past years – but bigger pop3

ulation studies are needed to confirm this hypothesis.

OP compounds: “immunotoxin” potential in human and non-target organisms Due to the overuse of pesticides, OP-residues have contaminated drinking water, grains, vegetables, fruits, and other food items, and for many years this has provoked a global health concern about potential neurological disorders.4 These chemicals block the activity of

acetylcholine esterase at synapses, leading to a disproportionate accumulation of the neurotransmitter acetylcholine.

Moreover, recent investigations have linked

OPs to several biological responses mediating severe toxic outcomes. Studies have sug-

ther later or acutely. For example, exposure to carbamates (OP) is followed by hypersensitivity reactions, inflammatory/chronic man-

ifestations, or cancers. Short-term exposure to atrazine, a widely used herbicide, can persist for a longer duration even after termination of the exposure.9

The agricultural uses of OP pesticides are

gaining in popularity, and they account for

more than 30% of global insecticide sales. The global market for sales of OP pesticides is ex-

pected to grow by a compound annual growth rate of 5.5% during the period 2018–2023.10

Unfortunately, in many developing coun-

tries, OPs are being used indiscriminately in ways that could further amplify unintentional exposure to these compounds.

Systemic lupus erythematosus The etiology of SLE is not well understood, but it is known that certain demographic groups are more affected than others. SLE is signifi-

cantly more common among women; approximately 90% of patients diagnosed with SLE are women.

CONCLUSION: To summarize, we have limited understanding of whether diseases such as SLE or other manifestations (child adiposity,16 Gulf War illness (GWI),17 chronic fatigue syndrome18 …) present themselves at an earlier living age following exposure to environmental factors. Likewise, our understanding is limited as to whether environmental factors can alter the body’s natural defense mechanism – “the human intestinal virome” – so it will attack the body instead of defending it, thereby escalating SARS-COV-2 – pathogenicity. ing, environmental pollutants, infections, sex

hormones and other factors. Studies of (NZB 12

x NZW) F1 lupus-prone mice have pointed to

a role of chemicals (silica) in the pathogenesis of SLE and human smoking although 13


the evidence in human observational studies has been limited until now. Clear evidence has been missing for ethical reasons.

Further studies are needed to examine any

potential relationship between exposure to pesticides/chemicals via e.g. food intake and

CYP polymorphism as exemplified by the SLE model. Whether or not changes in the human

intestinal virome result in a defense or attack mechanism is just at the beginning of our understanding.15

Atopic dermatitis is a persistent skin disease that commonly begins in childhood. It is characterized

by intense itching, eczematous and irritating dryness of the skin. Although a predisposition to at-

CONCLUSION: Our findings are interesting in view of the increased use of antibiotics around the world. Further understanding is needed as to how exactly antibiotics affect the pathways that activate the onset of atopic dermatitis. It has been suggested that the effect of antibiotics may vary depending on how antibiotics act on the skin, the gut, duration of use, their mode of action and route of administration. It may also be important to see if the use of multiple drugs at the same time has a different effect than single dosed agents.2

Exposure to antibiotics or environmental factors? In the total population which comprised more than 700,000 singleton children aged between 3 and 9 years, we found that exposure to antibiotics during pregnancy or the first year of life was associated with a higher risk of atopic dermatitis during early childhood. However, when we accounted for familial and other environmental factors by sibling analysis, we found that exposure to antibiotics in pregnancy was not associated with a greater risk of atopic dermatitis. However, exposure during the first year of life was still associated with a

residence, income, migration, prescribed medi-

Furthermore, when we consider the association

Against this background, we recently published a scientific article in JAMA network open1 using a

nationwide study to test the theory that the use of antibiotics during pregnancy or during the first

year of life is associated with an increased risk of atopic dermatitis.

Low prevalence of patients diagnosed with psoriasis in Nuuk: a call for increased awareness of chronic skin disease in Greenland This study set out to estimate the age- and gender-specific prevalence of psoriasis in Nuuk, Greenland. No overall gender-specific difference in prevalence was observed. Further, the study showed a low prevalence of patients diagnosed with psoriasis in Nuuk.

Psoriasis around the world Psoriasis is a multifactorial polygenic chronic, immune-mediated inflammatory skin disease characterized by the formation of sharply demarcated, scaly erythematous plaques.2 Psoriasis is estimated to affect 125 million people worldwide. In Europe, it is estimated that approximately 5 million people suffer from psoriasis, while 7 million people in the US have psoriasis.

In western countries, the prevalence of psoria-

sis is believed to be around 2–4%,3-5 while the highest prevalence of psoriasis is found in the Scandinavian population. In Denmark, approximately

2.2–2.8% of the population suffer from psoriasis.6,7

The self-reported lifetime prevalence of psoriasis in northern Norway increased from 4.8% in 1979–

1980 to 11.4% in 2007–2008, indicating an increased

awareness of the disease over the last 40 years.8 Due to difficulties in accurately identifying and

documenting the disease, psoriasis is believed to be underdiagnosed and undertreated in many countries around the world.5

Pligtoplysninger/Forkortet produktresumé Taltz 80 mg injektionsvæske, opløsning i fyldt pen og i fyldt injektionssprøjte (ixekizumab) Indikationsområde: Plaque-psoriasis: Taltz er indiceret til behandling af moderat til svær plaque-psoriasis hos voksne, der er kandidater til systemisk behandling. Pædiatrisk plaque-psoriasis: Taltz er indiceret til behandling af moderat til svær plaque-psoriasis hos børn og unge fra 6 år med en vægt på mindst 25 kg, der er kandidater til systemisk behandling. Psoriasisartrit: Taltz, alene eller i kombination med methotrexat, er indiceret til behandling af aktiv psoriasisartrit hos voksne patienter, der ikke har responderet tilstrækkeligt på eller ikke tåler et eller flere sygdomsmodificerende antireumatiske lægemidler (DMARD) (se SPC pkt. 5.1). Aksial spondylartrit: Ankyloserende spondylitis (radiografisk aksial spondylartrit): Taltz er indiceret til behandling af aktiv ankyloserende spondylitis hos voksne patienter, der ikke har responderet tilstrækkeligt på konventionel behandling. Nonradiografisk aksial spondylartrit: Taltz er indiceret til behandling af aktiv nonradiografisk aksial spondylartrit hos voksne patienter med objektive tegn på inflammation indikeret ved forhøjet C-reaktivt protein (CRP) og/eller magnetisk resonans (MR) scanning, der ikke har responderet tilstrækkeligt på nonsteroide anti-inflammatoriske lægemidler (NSAID’er). Dosering: Taltz skal anvendes under vejledning og supervision af en læge med erfaring i diagnosticering og behandling af sygdomme, for hvilke Taltz er indiceret. Plaque-psoriasis hos voksne: Den anbefalede dosis er 160 mg som subkutan injektion (to injektioner a 80 mg) ved uge 0, efterfulgt af 80 mg (én injektion) ved uge 2, 4, 6, 8, 10 og 12 og herefter vedligeholdelsesdosis på 80 mg (én injektion) hver 4. uge. Pædiatrisk plaque-psoriasis (6 år og derover): Der foreligger ingen data for sikkerhed og virkning hos børn under 6 år (se SPC pkt. 5.1). Tilgængelige data understøtter ikke en dosering ved en vægt under 25 kg. Den anbefalede dosis givet ved subkutan injektion hos børn er baseret på følgende vægtkategorier: Barnets vægt: Højere end 50 kg, anbefalet startdosis (uge 0): 160 mg (to injektioner a 80 mg), og herefter anbefalet dosis hver 4. uge: 80 mg. Barnets vægt: 25 til 50 kg, anbefalet startdosis (uge 0): 80 mg, og herefter anbefalet dosis hver 4. uge: 40 mg. Psoriasisartrit: Den anbefalede dosis er 160 mg som subkutan injektion (to injektioner a 80 mg) ved uge 0 og herefter 80 mg (én injektion) hver 4. uge. For patienter med psoriasisartrit og samtidig moderat til svær plaque-psoriasis, er den anbefalede dosis den samme som for plaque-psoriasis. Aksial spondylartrit (radiografisk og nonradiografisk): Den anbefalede dosis er 160 mg (to injektioner a 80 mg) som subkutan injektion ved uge 0 og herefter 80 mg hver 4. uge (se SPC pkt. 5.1). For alle indikationer (plaque-psoriasis hos børn og voksne, psoriasisartrit, aksial spondylartrit) bør det overvejes at seponere behandlingen hos patienter, der ikke har vist respons efter 16 til 20 ugers behandling. Patienter med partielt respons initialt kan i visse tilfælde efterfølgende opnå bedring ved fortsat behandling ud over 20 uger. Pædiatrisk psoriasisartrit: Taltz’ sikkerhed og virkning hos børn og unge i alderen 2 år til under 18 år i behandlingen af psoriasisartrit (en kategori af juvenil idiopatisk artrit) er endnu ikke klarlagt. Der foreligger ingen data. Det er ikke relevant at anvende Taltz til børn under 2 år for indikationen psoriasisartrit.Taltz skal administreres som subkutan injektion. Bivirkninger: Meget almindelige (≥ 1/10): Infektion i øvre luftveje, reaktioner på injektionsstedet. Almindelige (≥ 1/100 til < 1/10): Tinea-infektion, Herpes Simplex (mukokutan), orofaryngeale smerter, kvalme. Ikke almindelig (≥ 1/1.000 til < 1/100): Influenza, rhinitis, oral candidiasis, konjunktivitis, cellulitis, neutropeni, trombocytopeni, angioødem, urticaria, udslæt, eksem, inflammatorisk tarmsygdom. Sjælden (1/10.000 til < 1/1.000): Anafylaksi. Kontraindikationer: Alvorlig overfølsomhed over for det aktive stof eller over for et eller flere af hjælpestofferne. Klinisk vigtige aktive infektioner (f.eks. aktiv tuberkulose, se nedenfor). Særlige advarsler og forsigtighedsregler: Behandling med Taltz er forbundet med en øget forekomst af infektioner, f.eks. infektion i øvre luftveje, oral candidiasis, konjunktivitis og tinea-infektioner. Taltz bør anvendes med forsigtighed hos patienter med en klinisk vigtig kronisk infektion eller en anamnese med tilbagevendende infektion. Patienter skal instrueres i at søge læge, hvis der opstår tegn eller symptomer, der tyder på en infektion. Hvis der udvikles en infektion, skal patienten overvåges nøje, og Taltz skal seponeres, hvis patienten ikke responderer på standardbehandling, eller hvis infektionen bliver alvorlig. Behandlingen med Taltz må ikke genoptages, før infektionen er i bedring. Taltz må ikke gives til patienter med aktiv tuberkulose (TB). Hos patienter med latent TB skal behandling mod TB overvejes, før behandling med Taltz indledes. Alvorlige overfølsomhedsreaktioner, herunder tilfælde af anafylaksi, angioødem, urticaria og i sjældne tilfælde sene (10-14 dage efter injektion) overfølsomhedsreaktioner inklusive udbredt urticaria, dyspnø og høje antistoftitre, er rapporteret. Hvis der opstår en alvorlig overfølsomhedsreaktion, skal administration af Taltz omgående ophøre og relevant behandling indledes. Inflammatorisk tarmsygdom (inklusive Chrons sygdom og colitis ulcerosa): Der er blevet rapporteret om tilfælde af nyopstået eller forværret inflammatorisk tarmsygdom hos patienter i behandling med Taltz (se SPC pkt. 4.8). Taltz anbefales ikke til patienter med inflammatorisk tarmsygdom. Hvis en patient udvikler tegn og symptomer på inflammatorisk tarmsygdom eller oplever forværring af en allerede eksisterende inflammatorisk tarmsygdom, skal Taltz seponeres og passende medicinsk behandling bør påbegyndes.Taltz bør ikke anvendes sideløbende med levende vacciner. Interaktion: Resultater fra et lægemiddelinteraktionsstudie hos patienter med moderat til svær psoriasis har vist at 12 ugers administration af ixekizumab i kombination med lægemidler som metaboliseres af CYP3A4 (dvs. midazolam), CYP2C9 (dvs. warfarin), CYP2C19 (dvs. omeprazol), CYP1A2 (dvs. koffein) eller CYP2D6 (dvs. dextromethorfan) ikke har en klinisk signifikant påvirkning på farmakokinetikken af disse lægemidler. Fertilitet, graviditet og amning: Fertile kvinder skal anvende sikker kontraception under behandlingen og i mindst 10 uger efter endt behandling. Som en sikkerhedsforanstaltning bør behandling med Taltz undgås under graviditet. Det skal besluttes, om amning skal ophøre eller behandling med Taltz seponeres, idet der tages højde for fordelene ved amning for barnet i forhold til de terapeutiske fordele for moderen. Virkningen af ixekizumab på fertiliteten hos mennesker er ikke blevet undersøgt. Dyrestudier indikerer hverken direkte eller indirekte skadelige virkninger, hvad angår fertilitet. Overdosering: Doser på op til 180 mg er blevet administreret subkutant i kliniske studier uden dosisbegrænsende toksicitet. I tilfælde af overdosering anbefales det, at patienten monitoreres for tegn eller symptomer på bivirkninger, og at relevant symptomatisk behandling omgående indledes.
