Choroba addisona
Epidemiologia
Choroba Addisona, czyli pierwotna niedoczynność kory nadnerczy, charakteryzuje się zróżnicowaną częstością występowania na świecie, wahającą się od 40 do 140 przypadków na milion populacji, z najwyższą częstością w krajach nordyckich (np. Islandia 221/milion, Norwegia 144/milion). Roczna zachorowalność wynosi 4,4-6,2 na milion. Etiologia choroby różni się regionalnie: w krajach rozwiniętych dominuje autoimmunologiczne zapalenie nadnerczy (70-90% przypadków), natomiast w krajach rozwijających się, zwłaszcza w Afryce Subsaharyjskiej, znaczącą rolę odgrywa gruźlica (do 34%). Choroba najczęściej diagnozowana jest u dorosłych w wieku 30-50 lat, z wyraźną przewagą kobiet (stosunek do mężczyzn nawet 12,3:1), choć w młodszych grupach wiekowych dominują mężczyźni. Współistnienie innych chorób autoimmunologicznych, takich jak cukrzyca typu 1, niedoczynność przytarczyc czy choroby tarczycy, występuje u około 50% pacjentów. Wysoka odziedziczalność (0,97; 95% CI 0,88-0,99) i rodzinne występowanie podkreślają znaczenie czynników genetycznych.
Epidemiologia choroby Addisona
Choroba Addisona (pierwotna niedoczynność kory nadnerczy) jest rzadkim schorzeniem endokrynologicznym o zróżnicowanej częstości występowania w różnych regionach świata. Według najnowszych danych, częstość występowania choroby Addisona waha się od 40 do 140 przypadków na milion populacji, choć niektóre badania wskazują, że liczba ta może być wyższa, sięgając nawet 185-220 przypadków na milion mieszkańców.123 Roczna zachorowalność (liczba nowych przypadków) szacowana jest na poziomie 4,4-6,2 przypadków na milion osób.45
W Wielkiej Brytanii częstość występowania choroby Addisona wynosi około 39 przypadków na milion populacji, w Danii około 60 przypadków na milion, natomiast w Islandii odnotowano wyższą częstość – 22,1 przypadków na 100 000 mieszkańców (czyli 221 na milion).6 Z kolei w Korei częstość ta jest znacznie niższa i wynosi zaledwie 4,17 przypadków na milion populacji.7 W Wielkiej Brytanii zdiagnozowanych jest około 8 400 osób z chorobą Addisona, z ponad 300 nowymi przypadkami diagnozowanymi każdego roku.89
Według nowszych badań epidemiologicznych obserwuje się trend wzrostowy w częstości występowania choroby Addisona, szczególnie wśród kobiet. Może to wynikać ze zwiększonej predyspozycji do chorób autoimmunologicznych, ale również z poprawy metod diagnostycznych i większej świadomości tego schorzenia wśród lekarzy.1011
Rozkład demograficzny
Choroba Addisona może wystąpić w każdym wieku, jednak najczęściej diagnozowana jest u osób dorosłych w wieku 30-50 lat.1213 Warto zauważyć, że istnieje wyraźna przewaga kobiet wśród chorych, ze stosunkiem częstości występowania u kobiet do mężczyzn wynoszącym nawet 12,3:1 według niektórych źródeł.14 Inne badania wskazują na mniej wyraźną, ale wciąż znaczącą przewagę kobiet.15
Interesujący jest fakt, że w przypadku izolowanej autoimmunologicznej niedoczynności kory nadnerczy pojawiającej się w pierwszych dwóch dekadach życia, dominują chorzy płci męskiej (71%), natomiast wśród osób diagnozowanych po 30. roku życia przeważają kobiety (81%).1617
Nie stwierdzono istotnych predyspozycji etnicznych do występowania choroby Addisona, choć częstość jej występowania może być wyższa w krajach nordyckich.1819
Czynniki ryzyka i choroby współistniejące
Do głównych czynników ryzyka rozwoju autoimmunologicznej choroby Addisona (stanowiącej 70-90% przypadków w krajach rozwiniętych) należą inne choroby o podłożu autoimmunologicznym:2021
- Cukrzyca typu 1
- Niedoczynność przytarczyc
- Niedoczynność przysadki
- Anemia złośliwa
- Choroba Gravesa-Basedowa
- Przewlekłe zapalenie tarczycy
- Opryszczkowate zapalenie skóry (Dermatitis herpetiformis)
- Bielactwo
- Miastenia gravis
Co najmniej jedna współistniejąca choroba autoimmunologiczna towarzyszy chorobie Addisona w około 50% przypadków.23 Wśród pacjentów z cukrzycą typu 1, około 1% choruje również na chorobę Addisona, podczas gdy 2-5% ma chorobę autoimmunologiczną tarczycy (głównie niedoczynność).24
Istotnym czynnikiem ryzyka jest również obecność choroby Addisona w rodzinie. Badania wykazały wysoką odziedziczalność tego schorzenia (szacowaną nawet na 0,97; 95% CI 0,88-0,99), co wskazuje na silny wpływ czynników genetycznych.25 Około 3,6-10% pacjentów z chorobą Addisona zgłasza występowanie tego schorzenia u członków rodziny.2627
Zachorowalność w różnych regionach świata
Istnieją znaczące różnice w częstości występowania choroby Addisona w różnych regionach świata, co może być związane z czynnikami genetycznymi, środowiskowymi oraz różnicami w możliwościach diagnostycznych poszczególnych krajów.28
| Kraj/Region | Częstość występowania (na milion populacji) |
|---|---|
| Norwegia | 144 |
| Islandia | 221 |
| Dania | 60 |
| Wielka Brytania | 39 |
| Korea | 4,17 |
| RPA (szacunkowo) | 3 |
Częstość występowania choroby Addisona jest szczególnie wysoka w krajach nordyckich, osiągając 144 przypadki na 100 000 w Norwegii i 221 przypadków na 100 000 w Islandii.32 Natomiast w krajach rozwijających się, w tym w Afryce Subsaharyjskiej, częstość ta jest znacznie niższa, co może być związane z niedostateczną diagnostyką.33
Etiologia i jej wpływ na epidemiologię
W krajach rozwiniętych główną przyczyną choroby Addisona jest autoimmunologiczne zapalenie nadnerczy, odpowiedzialne za 70-90% przypadków.3435 Proces autoimmunologiczny prowadzi do stopniowego niszczenia kory nadnerczy, co skutkuje niedostateczną produkcją hormonów kortyzolu i aldosteronu.
W przeciwieństwie do krajów rozwiniętych, w krajach rozwijających się znaczącą przyczyną choroby Addisona pozostaje gruźlica. W krajach rozwiniętych gruźlica odpowiada za około 7-20% przypadków, natomiast w krajach rozwijających się lub wśród populacji imigrantów odsetek ten jest znacznie wyższy.3637
Różnice w etiologii między regionami przedstawiają się następująco:38
- Rejon Bliskiego Wschodu i Afryki Północnej:
- Choroby autoimmunologiczne: 60,3%
- Gruźlica: 4,1%
- AIDS: 1%
- Afryka Subsaharyjska:
- Choroby autoimmunologiczne: 20%
- Gruźlica: 34%
- AIDS: 29,8%
Wraz z lepszą kontrolą gruźlicy w krajach rozwiniętych, ogólna częstość występowania choroby Addisona zmniejszyła się, jednak jednocześnie obserwuje się wzrost liczby przypadków związanych z autoimmunologiczną etiologią.40
Czynniki genetyczne w epidemiologii choroby Addisona
Badania genetyczne wskazują na znaczący wpływ czynników dziedzicznych w rozwoju autoimmunologicznej choroby Addisona. Zgodność zachorowalności wśród bliźniąt jednojajowych szacowana jest na 0,71 (95% CI 0,40-0,90), co potwierdza silny wpływ czynników genetycznych.41
Występowanie rodzinne choroby Addisona jest szczególnie wysokie wśród rodzeństwa. Wskaźnik ryzyka (SIR) dla rodzeństwa jest wyjątkowo wysoki, osiągając nawet 909 dla rodzeństwa jednojajowego zdiagnozowanego przed 10. rokiem życia. Pozostaje on wysoki (32) nawet u osób zdiagnozowanych po 29. roku życia.42
Choroba Addisona wykazuje związek z wieloma innymi chorobami autoimmunologicznymi, w tym chorobami tarczycy, cukrzycą typu 1, a także rzadszymi schorzeniami, takimi jak zespół Guillaina-Barrégo, miastenia gravis, polimialgia reumatyczna i zespół Sjögrena.43
Przebieg kliniczny i nadzór epidemiologiczny
Przebieg choroby Addisona jest zazwyczaj podstępny, z powolnym rozwojem objawów, co może opóźniać rozpoznanie. Pierwsze objawy autoimmunologicznej niedoczynności kory nadnerczy to zwykle wzrost aktywności reniny w osoczu w połączeniu z normalnym lub niskim stężeniem aldosteronu w surowicy, co sugeruje, że początkowo zajęta jest strefa kłębkowata kory nadnerczy.44
Choroba często pozostaje nierozpoznana przez długi czas, a diagnoza stawiana jest dopiero po wystąpieniu przełomu nadnerczowego. Szacuje się, że około 16% pacjentów z chorobą Addisona (376/2302) prezentuje się w stanie przełomu nadnerczowego w momencie diagnozy.45
Przełom nadnerczowy w epidemiologii
Przełomy nadnerczowe są stosunkowo rzadkie, z szacowaną częstością występowania 5-10 przypadków na 100 pacjento-lat. Około 40% pacjentów z chorobą Addisona doświadcza co najmniej jednego przełomu nadnerczowego w ciągu życia, a 20% doświadcza więcej niż jednego.46
Przełom nadnerczowy stanowi zagrożenie życia i wymaga natychmiastowego leczenia. Może być wywołany de novo, na przykład przez krwotok do nadnerczy, lub w wyniku ostrego zdarzenia nałożonego na przewlekłą lub niedostatecznie leczoną niewydolność kory nadnerczy.47
Śmiertelność i chorobowość
Nawet po zdiagnozowaniu i odpowiednim leczeniu, ryzyko zgonu u pacjentów z chorobą Addisona jest ponad dwukrotnie wyższe w porównaniu z populacją ogólną.48 Chorobowość i śmiertelność związane z chorobą Addisona wynikają zwykle z niepowodzenia lub opóźnienia w ustaleniu rozpoznania, bądź z niepowodzenia w wprowadzeniu odpowiedniego leczenia zastępczego glikokortykosteroidami i mineralokortykosteroidami.49
Badania wykazały, że kobiety z autoimmunologiczną chorobą Addisona mają zwiększone ryzyko choroby niedokrwiennej serca, ze skorygowanym współczynnikiem ryzyka (aHR) wynoszącym 2,15 w porównaniu z grupą kontrolną.50
U pacjentów z cukrzycą typu 1 lub 2, którzy jednocześnie cierpią na chorobę Addisona, wskaźnik śmiertelności jest wyższy niż u osób z samą cukrzycą.51
Badanie kobiet z autoimmunologiczną chorobą Addisona wykazało, że 10,2% z nich rozwija pierwotną niewydolność jajników (POI; tj. menopauzę przed 40. rokiem życia), przy czym jedna trzecia przypadków POI występuje przed 30. rokiem życia.52
Wyzwania w nadzorze epidemiologicznym
Nadzór epidemiologiczny nad chorobą Addisona napotyka na szereg wyzwań, które mogą wpływać na dokładność danych dotyczących częstości występowania tego schorzenia.53
Główne trudności w monitorowaniu epidemiologicznym choroby Addisona obejmują:5455
- Niespecyficzne objawy początkowe, które mogą być przypisywane innym schorzeniom
- Opóźniona diagnoza (często od 3 do 6 miesięcy od wystąpienia pierwszych objawów)
- Różnice w dostępie do opieki zdrowotnej między regionami
- Zróżnicowane możliwości diagnostyczne w różnych krajach
- Niskie nakłady na służbę zdrowia w niektórych regionach (np. w Afryce Subsaharyjskiej roczne wydatki rządowe na zdrowie per capita wahają się od 942 USD w RPA do 32 USD w Demokratycznej Republice Konga)
W krajach rozwiniętych wprowadzono rejestry chorób rzadkich, które pomagają w monitorowaniu epidemiologii choroby Addisona. Na przykład w Wielkiej Brytanii pacjenci z chorobą Addisona są rejestrowani w Krajowym Rejestrze Wad Wrodzonych i Chorób Rzadkich (National Congenital Anomaly and Rare Disease Registration Service – NCARDRS).57
Tendencje w epidemiologii choroby Addisona
Najnowsze badania wskazują na wzrost częstości występowania choroby Addisona w niektórych regionach świata. Przykładowo, badanie przeprowadzone w Banbury w Oxfordshire (Wielka Brytania) wykazało częstość występowania na poziomie 185 przypadków na milion mieszkańców, co jest znacznie wyższe niż wcześniej raportowane dane.58
Wzrost ten może być spowodowany:5960
- Zwiększoną świadomością choroby wśród lekarzy
- Udoskonalonymi metodami diagnostycznymi
- Rzeczywistym wzrostem częstości występowania chorób autoimmunologicznych w populacji
- Lepszym raportowaniem i rejestracją przypadków
W Nowej Południowej Walii (Australia) zaobserwowano znaczący wzrost liczby przyjęć szpitalnych związanych z diagnozą złośliwości nadnerczy z towarzyszącą niedoczynnością kory nadnerczy. Częstość przyjęć szpitalnych z powodu złośliwości nadnerczy wzrosła z 129,9 na milion w 2006 roku do 215,7 na milion w 2017 roku (p<0,01). W tym samym okresie częstość diagnoz niedoczynności kory nadnerczy wzrosła z 1,2 na milion do 3,4 na milion (p<0,01).61
Znaczenie wczesnego rozpoznania i edukacji
Ze względu na rzadkość występowania choroby Addisona (szacowaną na 1 przypadek na 20 000 osób w Stanach Zjednoczonych i Europie Zachodniej), konieczne jest utrzymanie wysokiego poziomu podejrzenia klinicznego, aby uniknąć błędnego rozpoznania zagrażającego życiu przełomu nadnerczowego.62
Postęp w optymalizacji terapii zastępczej dla pacjentów z chorobą Addisona pozwolił chorym prowadzić normalne życie. Jednak ciągła edukacja pacjentów i pracowników służby zdrowia na temat nieustannie obecnego zagrożenia przełomem nadnerczowym jest niezbędna do ratowania życia pacjentów z tą chorobą.63
Chociaż choroba Addisona jest rzadka, jej częstość w populacji może być niedoszacowana z powodu przypadków niezdiagnozowanych.64 Istnieje przypuszczenie, że wielu pacjentów z tą chorobą pozostaje niezdiagnozowanych lub jest błędnie diagnozowanych jako cierpiących na inne schorzenia, takie jak zaburzenia psychiczne czy anoreksja.65
Badania kliniczne nad chorobą Addisona są prowadzone na całym świecie. Według danych z ClinicalTrials.gov, przeprowadzono co najmniej 25 badań klinicznych, w tym 1 aktywne, 14 zakończonych i 4 w fazie rekrutacji.66 Prowadzenie tych badań jest kluczowe dla lepszego zrozumienia choroby, poprawy diagnostyki i leczenia.
Rola lekarzy podstawowej opieki zdrowotnej
Lekarze podstawowej opieki zdrowotnej odgrywają kluczową rolę we wczesnym wykrywaniu choroby Addisona, ponieważ są często pierwszym kontaktem dla pacjentów. Podstępny początek choroby może stanowić wyzwanie dla wczesnej diagnozy, dlatego konieczne jest utrzymanie wysokiego poziomu czujności klinicznej.67
Choroba Addisona powinna pozostać w diagnostyce różnicowej u pacjentów z następującymi objawami:68
- Utrata masy ciała
- Hipotensja
- Hiperpigmentacja
- Zmęczenie
- Zaburzenia elektrolitowe (hiponatremia, hiperkaliemia)
Zachowanie czujności, proaktywne podejście i edukacja pacjentów pozwalają lekarzom pomóc chorym w unikaniu przełomów nadnerczowych i utrzymaniu odpowiedniej jakości życia, co prowadzi do poprawy wyników leczenia.69
Wyzwania w diagnozowaniu osób starszych
Badania epidemiologiczne dotyczące niedoczynności kory nadnerczy wśród osób starszych są ograniczone. Czynniki przyczyniające się do rozwoju choroby oraz jej objawy nie są dobrze poznane w tej grupie wiekowej.70
Częstość występowania niedoczynności kory nadnerczy u osób starszych wydaje się rosnąć, ale choroba jest często nierozpoznawana ze względu na niespecyficzną prezentację. Badanie przeprowadzone na Tajwanie wykazało wzrost częstości występowania niedoczynności kory nadnerczy z różnych przyczyn w ciągu 13 lat z 6,4 do 15,2 na 100 000. Może to być spowodowane starzeniem się populacji, wzrostem częstości występowania chorób podstawowych prowadzących do niedoczynności kory nadnerczy oraz lepszymi możliwościami diagnostycznymi.71
U osób starszych niedoczynność kory nadnerczy często objawia się niespecyficznie, co prowadzi do opóźnionej diagnozy. Hipotensja jest najczęstszą manifestacją niedoczynności kory nadnerczy wśród starszych pacjentów w opiece rehabilitacyjnej. Klinicyści powinni być bardziej świadomi objawów niedoczynności kory nadnerczy, które są łatwo przeoczane w populacji osób starszych.72

- #1 Addison Disease: Practice Essentials, Epidemiologyhttps://emedicine.medscape.com/article/1096911-overview
The prevalence of Addison disease is 40-60 cases per 1 million population. […] The occurrence of Addison disease is rare. The reported prevalence in countries where data are available is 39 cases per 1 million population in Great Britain and 60 cases per 1 million population in Denmark. A study by Olafsson and Sigurjonsdottir found the prevalence of primary adrenal insufficiency in Iceland to be 22.1 per 100,000 population. […] A study by Hong et al found the prevalence of primary adrenal insufficiency in Korea to be 4.17 per 1 million population. […] Morbidity and mortality associated with Addison disease usually are due to failure or delay in making the diagnosis or a failure to institute adequate glucocorticoid and mineralocorticoid replacement. […] If not treated promptly, acute addisonian crisis may result in death. This may be provoked either de novo, such as by adrenal hemorrhage, or in the setting of an acute event superimposed on chronic or inadequately treated adrenocortical insufficiency.
- #2 Addison’s Disease – Endocrinology Advisorhttps://www.endocrinologyadvisor.com/ddi/addisons-disease/
In the general population, Addisons disease occurs in 1 in 5000 to 1 in 7000 individuals. Estimates of the prevalence vary by country; the differences may be due to genetic variation, environmental factors, and differences in each countrys diagnostic capabilities and medical database quality. Recent evidence suggests the prevalence of Addisons disease is increasing, particularly in women, perhaps due to an increased predisposition to autoimmune disease. […] Adrenal crises are relatively rare, with an estimated incidence of 5 to 10 cases per 100 patient-years. Approximately 40% of patients with Addisons disease experience at least 1 adrenal crisis during their lifetime, and 20% experience more than 1.
- #3 Causes of primary adrenal insufficiency (Addison disease) – UpToDatehttps://www.uptodate.com/contents/causes-of-primary-adrenal-insufficiency-addison-disease
When Thomas Addison described the disease that now bears his name, bilateral adrenal destruction by tuberculosis was its most common cause. Now tuberculosis accounts for only 7 to 20 percent of cases; autoimmune disease is responsible for 70 to 90 percent, with the remainder being caused by other infectious diseases, replacement by metastatic cancer or lymphoma, adrenal hemorrhage or infarction, or drugs. The prevalence of Addison disease in Western countries has been estimated at 35 to 60 per million, but three studies indicate it may be as high as 144 per million. […] Disseminated tuberculous or fungal infections are still a major cause of adrenal insufficiency in populations with a high prevalence of these diseases, but as tuberculosis has been better controlled, the overall incidence of Addison disease has decreased.
- #4 Addison Disease – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK441994/
Addison’s disease is rare, with an incidence of .6 per 100,000 of the population annually. The total number of people affected by this condition at a given time ranges from 4 to 11 per 100,000 of the population. […] In adults, the typical age of Addison disease presentation is 30 to 50 years and is more frequently seen in women. Risk factors for the autoimmune type of Addison’s disease, which is the most common type, include other autoimmune conditions: Type I diabetes, Hypoparathyroidism, Hypopituitarism, Pernicious anemia, Graves’ disease, Chronic thyroiditis, Dermatis herpetiformis, Vitiligo, Myasthenia gravis.
- #5 An Overview of Addison Disease – Clinical Advisorhttps://www.clinicaladvisor.com/features/an-overview-of-addison-disease/
The prevalence of AD in the US is estimated at 100 to 140 cases per 1,000,000 people, with an increasing incidence rate of 4.4 to 6.2 new cases per 1,000,000 people per year. Approximately 80% of AD cases are because of autoimmune etiology with the remaining 20% resulting from infectious processes, genetics, adrenal hemorrhage, surgical complications (adrenalectomy), or medication side effects. […] The insidious onset of AD can pose a challenge in early diagnosis. Clinicians in primary care are often the most accessible to patients and play a crucial role in the early detection and treatment of this condition. Although rare, AD should remain on the differential with patients presenting with weight loss, hypotension, hyperpigmentation, fatigue, and electrolyte disturbances, such as hyponatremia and hypokalemia. By remaining suspicious, being proactive, and providing education, primary care providers can assist patients in avoiding adrenal crises and maintaining adequate quality of life, which leads to improved patient outcomes.

- #11 Epidemiology of Adrenal Insufficiency Among Elderly Patients in a Convalescent Care Unit and One Year Outcome – European Journal of Geriatrics and Gerontologyhttps://ejgg.org/articles/doi/ejgg.galenos.2020.342
Adrenal insufficiency (AI) is associated with significant morbidity and mortality. The aim of this study is to describe the epidemiology, pattern of comorbidity and one-year outcome among elderly people after their initial diagnosis of AI. […] Epidemiological studies about AI among the elderly population are limited. Contributing factors and the signs and symptoms of AI are not well studied. […] The incidence of AI in elderly subjects is on the rising trend, yet, it is easily unrecognized; this study highlights the importance of infection that contributes to AI development and the non-specific presentation of this disease in older population. […] A study in Taiwan reported an increasing incidence of all-cause AI over a 13-year period of 6.4 to 15.2/105. This can be attributed by an ageing population, increasing incidence of underlying diseases that lead to AI and perhaps, better diagnostic ability.

Addison’s disease affects about 9 to 14 per 100,000 people in the developed world. […] The frequency rate of Addison’s disease in the human population is sometimes estimated at one in 100,000. Some put the number closer to 40144 cases per million population (1/25,0001/7,000). Addison’s can affect persons of any age, sex, or ethnicity, but it typically presents in adults between 30 and 50 years of age. Research has shown no significant predispositions based on ethnicity. […] About 70% of Addison’s disease diagnoses occur due to autoimmune reactions, which cause damage to the adrenal cortex.

- #15 Causes of primary adrenal insufficiency (Addison disease) – UpToDatehttps://www.uptodate.com/contents/causes-of-primary-adrenal-insufficiency-addison-disease
Patients who develop isolated autoimmune adrenal insufficiency during the first two decades of life are predominately male (71 percent), whereas those diagnosed during the third decade are equally male and female, and those diagnosed thereafter are predominately female (81 percent). […] The first evidence of autoimmune adrenal insufficiency is usually an increase in plasma renin activity in association with a normal or low serum aldosterone concentration, suggesting that the zona glomerulosa is involved initially.

- #17 Adrenal Insufficiency | Treatment & Management | Point of Carehttps://www.statpearls.com/point-of-care/17241
As many as 144 million individuals in the developed world may have Addison disease. When treated properly, patients can have a roughly normal lifespan. Untreated patients have a high mortality rate. […] The autoimmune form of adrenal insufficiency has a male-female predisposition based on the type of autoimmune condition. Females are more likely to have a polyglandular form, while isolated adrenal damage is more common in males in the first two decades. By the fourth decade, the isolated form is more common in women. […] Due to the diverse causes of adrenal insufficiency, no distinct group of individuals is at increased risk of disease. […] The epidemiology of adrenal insufficiency in children is not well-defined. Congenital adrenal hyperplasia (CAH) is the most common etiology of primary adrenal insufficiency in children, occurring once in 14,200 live births.
- #18 Addison’s disease – Wikipediahttps://en.wikipedia.org/wiki/Addison%27s_disease
Addison’s disease affects about 9 to 14 per 100,000 people in the developed world. […] The frequency rate of Addison’s disease in the human population is sometimes estimated at one in 100,000. Some put the number closer to 40144 cases per million population (1/25,0001/7,000). Addison’s can affect persons of any age, sex, or ethnicity, but it typically presents in adults between 30 and 50 years of age. Research has shown no significant predispositions based on ethnicity. […] About 70% of Addison’s disease diagnoses occur due to autoimmune reactions, which cause damage to the adrenal cortex.

[…] AAD is most common in the Nordic countries, but it is still a rare disease with published prevalence estimates ranging from 14.4 per 100,000 in Norway to 22.1 per 100,000 in Iceland. […] The prevalence in Sweden appears to be similar to that in Norway with one study identifying 1305 patients in a population of 9 million. […] Familial aggregation of AAD is evident from previous studies. […] In a cohort of 660 Norwegian patients with AAD, 10% had another family member (first to third-degree relative) with AAD and in a Swedish study, 6.4% of the patients with AAD without APS-1 reported having a family member (sibling, parent, child, or relative) with AAD.

APS-2 is the most common autoimmune polyendocrine syndrome. It has a prevalence of 1:20,000 in the general population, an annual incidence of 1-2:100,000 and a 3:1 ratio of females to males affected. […] In patients with APS-2, autoimmune thyroid disease is present in 70-75%, T1DM in 40-60% and Addisons disease in 40-50%. […] The mode of inheritance is complex as it is a polygenic disorder with autosomal dominant inheritance and incomplete penetrance. […] Associated with genes coding for protein that regulate the adaptive and innate immune system, mainly HLA genes. HLA-DR3, HLA-DR4, and non HLA genes, MICA5.1, CTLA-4, PTPN22, BACH, VTNR and the CD25-IL-2 receptor have been associated. Environmental risk factors may also contribute. […] Among patients with T1DM, 1% of patients have Addisons disease, whereas 2-5% have autoimmune thyroid disease (mainly hypothyroidism) and up to 5% have celiac disease. Up to 33% may have thyroid autoantibodies and 12% have transglutaminase autoantibodies.

The familial risk for AD was very high implicating genetic etiology, which for juvenile siblings may be ascribed to APS-1. The adult part of sibling risk was probably contributed by recessive polygenic inheritance. AD was associated with many common AIDs; some of these were known co-morbidities in AD patients while some other appeared to more specific for a familial setting. […] Due to the sparsity of population-based family studies in AD, we used Swedish hospital data to characterize familial clustering of concordant (between AD) and discordant (AD and other AIDs). […] The present nation-wide study covered a rare AID, which accounted for 0.4% of all hospitalized AIDs in Sweden. Familial AD accounted for 3.6% among all AD patients. We provided novel population-based familial risk estimates, which were very high, 41.49, and equal for men and women.

A surprising finding was that most familial cases (54/62) were siblings rather than offspring of affected parents. The sibling risk was remarkably high, reaching 909 for the youngest singleton siblings but remaining as high as 32 in those diagnosed past age 29 years. The risk for twins was 323, and all but one twin were diagnosed past age 29 years. […] In summary, we found a very high familial risk for AD, particularly among siblings. The juvenile component of the risk could be ascribed to ASP-1. The adult component of sibling risk was probably contributed to by polygenic inheritance. AD was associated with many common AIDs, some of which were known co-morbidities in AD patients.

[…] The likely causes of PAI in Sub-Saharan Africa (SSA) vs the Middle East and North Africa (MENA) regions included autoimmune disease (20% vs 60.3%; P0.001), tuberculosis (34% vs 4.1%; P0.001), AIDS (29.8% vs 1%; P0.001), malignancy, and genetic conditions. […] Sixteen percent of AD patients (376/2302) presented in an adrenal crisis. […] Through the perception and practice of healthcare professionals, we identified significant challenges in the diagnosis and management of PAI which may herald high mortality. […] The estimated prevalence of PAI in South Africa is three per million, in contrast to Western countries in which prevalence estimates vary from 30 per million to 221 per million.

The diagnosis of PAI is often delayed by between 3 and 6 months. […] The annual government health spending per capita in SSA ranges from $942 (South Africa) to $32 in (Democratic Republic of Congo), with a median of $109 for all African countries. […] The study has strengths and weaknesses that are worth noting: The main limitation stems from the nature of the study being a physicians survey rather than a patients series. […] This is the first Africa-wide and MENA study of primary adrenal insufficiency, demonstrating that there are substantial barriers to diagnosis and management, and these may likely herald high mortality.

This study aimed to investigate the lived experiences and issues central to patients with Addisons disease when they are hospitalised due to an adrenal crisis. […] There is no epidemiology data for Addisons disease in Aotearoa New Zealand, although internationally the prevalence in western countries is estimated to be 118 per million population. […] Increasing awareness and knowledge of healthcare practitioners in primary and secondary settings will improve the rate of diagnosis and reduce the risk of a life-threatening adrenal crisis. […] The experiences of being diagnosed as shared by participants was consistent with other literature. […] The journey to diagnosis is experienced as long and vague with patients encountering multiple healthcare professionals and undertaking multiple interventions.

In the general population, Addisons disease occurs in 1 in 5000 to 1 in 7000 individuals. Estimates of the prevalence vary by country; the differences may be due to genetic variation, environmental factors, and differences in each countrys diagnostic capabilities and medical database quality. Recent evidence suggests the prevalence of Addisons disease is increasing, particularly in women, perhaps due to an increased predisposition to autoimmune disease. […] Adrenal crises are relatively rare, with an estimated incidence of 5 to 10 cases per 100 patient-years. Approximately 40% of patients with Addisons disease experience at least 1 adrenal crisis during their lifetime, and 20% experience more than 1.

Adrenal insufficiency (AI) causes considerable morbidity but may remain undiagnosed in patients with adrenal malignancy (AM). The epidemiology of AI and adrenal crises (AC) in AM is uncertain. […] There were 15,376 hospital admissions with a diagnosis of AM in NSW over the study period, corresponding to 1281 admissions/year. The AM admission rate increased significantly over the study period from 129.9/million to 215.7/million (p0.01). An AI diagnosis was recorded in 182 (1.2%) admissions, corresponding to an average of 2.1/million/year. This rate increased significantly over the years of the study from 1.2/million in 2006 to 3.4/million in 2017 (p0.01). […] Admission with a diagnosis of AM has increased over recent years and has been accompanied by an increase in AI diagnoses. While AI is diagnosed in a small proportion of patients with AM, ACs do occur in affected patients.

Primary adrenal insufficiency, or Addison disease, has many causes, the most common of which is autoimmune adrenalitis. In the United States and Western Europe, the estimated prevalence of Addison disease is one in 20,000 persons; therefore, a high clinical suspicion is needed to avoid misdiagnosing a life-threatening adrenal crisis (i.e., shock, hypotension, and volume depletion). […] Because the estimated prevalence of Addison disease is one in 20,000 persons in the United States and Western Europe, a high clinical suspicion is needed to avoid misdiagnosing a life-threatening adrenal crisis.

According to the National Organization for Rare Disorders (NORD), approximately 1 in 100,000 people in the United States have Addison’s disease. Experts estimate the overall prevalence as 40 to 60 people per million of the general population. However, this number may be inaccurate as there is expected to be many undiagnosed instances in the population. […] The condition affects males and females at the same rate. Although people of any age can develop Addison’s disease, it is most likely to occur in individuals between the ages of 30-50.

Adrenal crisis is a bit like DKA. It can either be caused by chronic adrenal insufficiency plus a trigger, or it can be caused by acute adrenal insufficiency alone. […] Addison’s disease (may be associated with other autoimmune disorders or endocrinopathies). […] Addison’s disease may initially be misdiagnosed as a psychiatric condition or anorexia nervosa. […] Mineralocorticoid deficiency only occurs in primary adrenal insufficiency (e.g., Addison’s disease), but not in secondary insufficiency (e.g., pituitary dysfunction). […] Aldosterone is deficient only in cases involving failure of the entire adrenal gland (e.g. Addison’s disease).

The prevalence of AD in the US is estimated at 100 to 140 cases per 1,000,000 people, with an increasing incidence rate of 4.4 to 6.2 new cases per 1,000,000 people per year. Approximately 80% of AD cases are because of autoimmune etiology with the remaining 20% resulting from infectious processes, genetics, adrenal hemorrhage, surgical complications (adrenalectomy), or medication side effects. […] The insidious onset of AD can pose a challenge in early diagnosis. Clinicians in primary care are often the most accessible to patients and play a crucial role in the early detection and treatment of this condition. Although rare, AD should remain on the differential with patients presenting with weight loss, hypotension, hyperpigmentation, fatigue, and electrolyte disturbances, such as hyponatremia and hypokalemia. By remaining suspicious, being proactive, and providing education, primary care providers can assist patients in avoiding adrenal crises and maintaining adequate quality of life, which leads to improved patient outcomes.

Adrenal insufficiency (AI) is associated with significant morbidity and mortality. The aim of this study is to describe the epidemiology, pattern of comorbidity and one-year outcome among elderly people after their initial diagnosis of AI. […] Epidemiological studies about AI among the elderly population are limited. Contributing factors and the signs and symptoms of AI are not well studied. […] The incidence of AI in elderly subjects is on the rising trend, yet, it is easily unrecognized; this study highlights the importance of infection that contributes to AI development and the non-specific presentation of this disease in older population. […] A study in Taiwan reported an increasing incidence of all-cause AI over a 13-year period of 6.4 to 15.2/105. This can be attributed by an ageing population, increasing incidence of underlying diseases that lead to AI and perhaps, better diagnostic ability.

The proportion of subjects with AI with age 80 is on the rising trend as reported in a nationwide survey. […] The most common indication for performing SST in our sample population was electrolytes abnormalities. This is one of the alerting sign for the diagnosis of AI. […] Inpatient and one year mortality were high in our study population. 11.6% of our sample died during the index hospitalization while the one year mortality was up to 40%. This reflects the severity of medical problems and the poor health status of our study sample. […] It is suggested that those frail elderly with a low or borderline electrolytes abnormalities and/or unexplained low blood pressure should have screening for AI. […] A certain proportion of elderly people with AI were unrecognized in acute hospital and present non-specifically. Infection of the chest and urinary tract were the most common comorbidity. Hypotension was the most common manifestation of AI among convalescence care elderly patients. Clinicians should be more aware of the signs and symptoms of AI, which is easily overlooked in the elderly population.
