A 27-year-old woman presented with multiple indurated, ill-defined, erythematous plaques and nodules distributed along her upper arms, back, abdomen and thighs (Figures 1-3). Cutaneous biopsies revealed inflammatory infiltrates with fibrotic changes within the dermis and septa. Serum α1-antitrypsin (A1AT) level was low at 0.30 g/l (RR: 1.10-2.40 g/l). The clinical, hematological and histological findings were in keeping with a diagnosis of A1AT deficiency panniculitis. Further genetic phenotyping revealed a homozygous ZZ variant. Panniculitis is a rare, but recognised cutaneous manifestation of A1AT deficiency. Histopathological examination usually reveals a lobular panniculitis, but may demonstrate septal involvement. It is often refractory to many medical treatments including corticosteroids and immunosuppressant. However, treatments with dapsone, tetracyclines and A1AT repositioning have been used with varying efficacy [1,2]. Although surgical debridement should be avoided in the acute stage, patients may seek surgery for cosmetic purposes.
Case Reports in Dermatology
Alpha-1 antitrypsin deficiency, although one of the most common genetic diseases, is a very rare and often undiagnosed cause of panniculitis. The authors present a case characterized by an acute involvement of several areas in the thorax, abdomen, and limbs, occurring after repetitive trauma of the perineal area caused by a long period of cycling. After performing the differential diagnosis and establishing etiology, the patient was started on augmentation therapy with plasma-derived synthetic human alpha-1 proteinase inhibitor and the disease has been under control since then. We recommend lifelong treatment with this medication. At the end of a 10-year follow-up, there has been no evidence of pulmonary emphysema or liver disease. The authors perform a concise review of the genetic and pathogenic mechanisms behind this disease, with a special focus on panniculitis and its treatment.

Background Alpha-1-antitrypsin is the principal serum protease inhibitor. In addition to the well-recognized association with early-onset emphysema and cirrhosis, alpha-1-antitrypsin deficiency may be associated with panniculitis. The treatment of this type of panniculitis presents a significant challenge. Previous attempts using immunosuppressive, antiinflammatory, and cytotoxic drugs have shown variable results.
American Journal of Medical Genetics, 1982
Alpha 1 antitrypsin phenotypes and serum levels are presented for a family in which two brothers have Weber Christian disease and a1 antitrypsin (PI) Z phenotypes. Clinical histories are described for these two men. A younger brother has the PI Z phenotype but does not have the disease, indicating that additional genetic and/or environmental factors contribute to the pathogenesis of Weber Christian disease. However, the two cases described provide additional evidence for a relationship between a 1 antitrypsin deficiency and the development of symptoms.
QJM, 1996
We describe the clinical presentation and outcome in a series of eight patients with systemic necrotizing vasculitis and severe alpha t -antitrypsin (AAT) deficiency followed up at three Swedish hospitals during 1968-92. We also review six other cases reported in the literature during the same period. Diagnosis of severe AAT deficiency was based on the presence of the PiZZ phenotype, or low plasma total trypsin inhibitory capacity, or a low plasma AAT concentration (10-40% of the normal mean value) and presence of the PiSZ or PiFZ phenotype. The diagnosis of systemic vasculitis was biopsy-verified in all eight patients. Pretreatment laboratory findings, treatment protocol, and outcome were reviewed in each of the 14 patients. Of the eight patients in the Swedish series, six had systemic vasculitis of the microscopic polyangiitis form, one had Wegener's granulomatosis, and another had Henoch-Schonlein purpura. In the series as a whole ( n = 1 4 ) , median age at diagnosis was 48 years (range 44-84), the median number of affected organs was eight, and all 14 patients had skin involvement, and either renal or joint involvement (in most cases both); 7 1 % (10/14) had emphysema; 57% (8/14) had hepatic abnormalities (two having cirrhosis, two fibrosis, and one multiple aneurysms in hepatic arteries); one patient who presented with acute ulcerative colitis developed manifest vasculitic syndrome three years later; and 64% (9/14) died, the major cause of death being renal failure. This syndrome, characterized by multiple organ involvement and fatal outcome, has been underdiagnosed. Physicians should be alert to the presence of the PiZ AAT deficiency gene in patients with systemic vasculitis, especially when the course is progressive or when the patient also has emphysema or cirrhosis. Awareness of those features may aid prompt recognition and enable early treatment.
Clinical Gastroenterology and Hepatology, 2012
α1-antitrypsin (A1AT) deficiency is an autosomal co-dominant disease that can cause chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC) in children and adults and increases risk for emphysema in adults. The development of symptomatic disease varies-some patients have life-threatening symptoms in childhood whereas others remain asymptomatic and healthy into old age. As a result of this variability, patients present across multiple disciplines, including pediatrics, adult medicine, hepatology, genetics, and pulmonology. This can give physicians the mistaken impression that the condition is less common than it actually is, and can lead to fragmented care that omits critical interventions commonly performed other specialists. We sought to present a rational approach for hepatologists to manage adult patients with A1AT deficiency.

Purpose of Review Commonly categorized as a rare disease, alpha-1 antitrypsin deficiency (AATD) is neither rare, when compared to many other genetic disorders, nor an actual disease, but rather a predisposition toward a wide variety of diseases. It is one of the most common genetic disorders which can lead to a spectrum of clinical manifestations, ranging from no symptoms to progressively debilitating systemic disease, most commonly affecting the lung and liver. It is therefore imperative for clinicians to recognize and be familiar with the spectrum of presentations, methods of diagnosis, and clinical management of AATD. It is also imperative for scientists to recognize the potential for progress in the management of this disorder. Recent Findings This review focuses on the current state of knowledge of AATD, including the wide range of presentations, diagnosis, and clinical management. In addition to the clinical implications of severe AATD, we discuss the relevance of heterozygous state with mild or moderate AATD in the development of both lung and liver disease. While our understanding of the multiple roles of alpha-1 antitrypsin (AAT) is on the rise, with appreciation of its immunomodulatory, anti-infective, and anti-inflammatory properties, this knowledge has yet to impact our ability to predict outcomes. We discuss nuances of augmentation therapy and review novel therapeutic approaches currently under investigation. Summary With the expanding knowledge about the complexities of AAT function and its clinical relevance, and with the increasing ability to diagnose early and intervene on AATD, it should be our goal to change the perception of AATD as a correctable inherited disorder rather than a fatal disease.
Mutation Research/Reviews in Mutation Research, 2017
Alpha-1-antitrypsin (AAT) is an acute phase secretory glycoprotein that inhibits neutrophil proteases like elastase and is considered as the archetype of a family of structurally related serine protease inhibitors termed serpins. Serum AAT predominantly originates from liver and increases three to five fold during host response to tissue injury and inflammation. The AAT deficiency is unique among the protein misfolding diseases in that it causes target organ injury by both loss-of-function and gain-of-toxic function mechanisms. Lack of its antiprotease activity is associated with premature development of pulmonary emphysema and loss of function due to accumulation of resultant aggregates in chronic obstructive pulmonary disease (COPD). This in turn markedly reduces the amount of AAT that is available to protect lungs against proteolytic attack by the enzyme neutrophil elastase. The coalescence of AAT deficiency, its reduced efficacy, and cigarette smoking or poor ventilation conditions have devastating effect on lung function. On the other hand, the accumulation of retained mutant proteins in endoplasmic reticulum of liver cells in a polymerized form rather than secreted into the blood in its monomeric form is associated with chronic liver disease and predisposition to hepatocellular carcinoma (HCC) by gain of toxic function. Liver injury resulting from this gain-of-toxic function mechanism in which mutant AAT retained in the ER initiates a series of pathologic events, eventually culminating at liver cirrhosis and HCC. Here in this review, we underline the structural, genetic, polymorphic, biochemical and pathological advances made in the field of AAT deficiency and further comprehensively emphasis on the therapeutic interventions available for the patient.
International wound journal, 2015
Wound healing disturbance is a common complication following surgery, but the underlying cause sometimes remains elusive. A 50-year-old Caucasian male developed an initially misunderstood severe wound healing disturbance following colon and abdominal wall surgery. An untreated alpha-1-antitrypsin (AAT) deficiency in the patient's medical history, known since 20 years and clinically apparent as a mild to moderate chronic obstructive pulmonary disease, was eventually found to be at its origin. Further clinical work-up showed AAT serum levels below 30% of the lower reference value; phenotype testing showed a ZZ phenotype and a biopsy taken from the wound area showed the characteristic, disease-related histological pattern of necrotising panniculitits. Augmentation therapy with plasma AAT was initiated and within a few weeks, rapid and adequate would healing was observed. AAT deficiency is an uncommon but clinically significant, possible cause of wound healing disturbances. An augme...
