We describe pathological findings utilizing autopsy tissue from several organs from a patient affected by a new variant of endemic pemphigus in El Bagre, Colombia, South America; our patient was receiving high-dosage immunosuppressors when hospitalized, and died suddenly following contact with a second patient affected by chicken pox. We performed studies utilizing hematoxylin and eosin, immunohistochemistry and direct immunofluorescence techniques on tissues from several organs. We detected the presence of varicella-zoster virus (VZV), as well as strong positivity for alpha 1 antitrypsin in the heart, kidneys, spleen, liver, skin, brain, lungs, pancreas, small and large intestines, and skeletal muscle. In regard to structural damage in the kidney and heart, we believe the observed damage is associated with the presence of autoantibodies to these organs, as both of them are rich in plakins, and patients with El Bagre endemic pemphigus foliaceus (EPF) present significant antibodies to plakin molecules. In patients with EPF, we recommend complete isolation of the patient when receiving high dosages of systemic immunosuppressive agents. We further suggest the clinical possibility of a synergistic, fatal interaction between active pemphigus foliaceus, VZV, herpes simplex virus, immunosuppressive agents and a systemic activation of alpha 1 antitrypsin. Thus, we suggest adequate bed spacing, barrier nursing and preventative testing for alpha 1 antitrypsin activation are warranted in these patients to address these complications.

We report a patient affected by El BagreEPF. Classically, due to limited therapeutic options in El Bagre, patients affected by generalized El Bagre-EPF are transferred to a reference hospital in Medellin, 45 min away by airplane.10–15 The patients are typically thus hospitalized, and undergo therapeutic baths in common tubs without special isolation or sterilization.

Report We report a 38-year-old Mestizo male presenting with generalized El Bagre-EPF who was hospitalized in Medellin after being referred from the endemic area in El Bagre. The initial physical examination revealed an ocular ulcer, clinically interpreted to be herpes virus infection (without confirmatory testing). The patient lived in the endemic area, and displayed clinical and histopathological features of EPF, as previously described.10–15 The patient also demonstrated direct (DIF) and indirect immunofluorescence skin epidermal staining between keratinocytes, consistent with previously described EPF diagnostic criteria. The patient serum contained antibodies to human total IgG and IgG4 against skin epidermal keratinocyte cell junctions.10–15 The patient serum also immunoprecipitated a Con-A affinity-purified bovine tryptic 45-kDa fragment of desmoglein 1 (Dsg1), and his serum also tested positive by: (1) immunoblotting for reactivity Dsg1 and plakin molecules; and (2) by diagnostic ELISA testing, as previously described.10–15 During the initial hospitalization, the patient denied systemic symptoms. No pre-treatment infectious disease testing was obtained before initiation of high-dosage immunosuppressant therapy. An initial dose of 15 mg/d of prednisone was initiated, increasing up to 120 mg/d, with the addition at that time of azothioprine at 50 mg/d. During the course of the hospitalization, the patient was receiving these dosages of Abreu Velez et al. 1 immunosuppressors without isolation from other patients. During the course of the hospitalization, the patient was also diagnosed with acquired molluscum contagiosum, in addition to furunculosis. The patient was thus started on empiric treatment for furunculosis with ciprofloxacin and topical bacitracin, without culture confirmation. The ‘‘ocular herpes’’ lesion was treated with topical acyclovir. Several days after the initiation of the immunosuppressive therapy, tests for tuberculosis and stool ova and parasite tests were negative. The furunculosis lesions were drained, and the lesions improved. The molluscum lesions were curettaged. Later, the patient was diagnosed with cellulitis of the thigh; prostaphilin was initiated following culture of the lesions, which demonstrated positivity for Staphylococcus aureus. During the course of the hospitalization, a urinary tract infection was also reported in the patient, again without culture confirmation. The patient was subsequently diagnosed with diabetes mellitus secondary to the corticosteroid therapy, and insulin was initiated. Days after, the patient clinically displayed signs of oral and esophageal candidiasis infection, and topical Nystatin was initiated, also empirically. Later, the patient reported abdominal pain, and a renal computerized axial tomography scan demonstrated urolithiasis and hydronephrosis of the left kidney. Serum renal studies at this time showed increased creatinine and blood urea nitrogen. The patient was hospitalized for a total period of 4 months, and received high doses of systemic immunosuppressors throughout the hospitalization. Near the end of this hospital course, the patient presented abruptly with numerous 2–4-mm vesicles and pustules with central crusting and small ulcerations over most of his body (Figs 1–3). Within 24 h of the onset of these lesions, an erythematous maculopapular eruption developed on the upper trunk and face. The papules Figure 1 (a–i) IHC staining.

Systemic acyclovir at 0.3 mg/kg/d was administered. Within the next 24 h, the vesicles became cloudy, and pruritus developed. A diagnosis of chicken pox/varicella was made, based upon the presence of a similar outbreak throughout the ward. No confirmatory laboratory tests were performed. The patient died 2 d Report 1 3 after the onset of the initial vesiculopustular cutaneous eruption, demonstrating clinical features of disseminated intravascular coagulation. Biopsies were taken of the maculopapular skin lesions at autopsy, and the collected tissue subsequently maintained in both buffered formalin and fresh frozen in OCT for hematoxylin and eosin (H&E), DIF and immunohistochemistry (IHC) studies.

Intercellular epidermal keratinocyte staining diagnostic of EPF was weak, likely secondary due to the significant, pre mortem immunosuppressant therapy. However, we were able to appreciate EPF punctate immunoreactivity inside several epidermal keratinocytes, as well against the epi- dermal basement membrane zone (BMZ) area. Additional EPF reactivity was noted against sebaceous glands and sweat glands, consistent with similar reactivity observed in pre mortem skin biopsies. In addition, reactivity against renal glomeruli and against heart cell junctions was clearly observed in the post mortem biopsies, despite the large dosages of immunosuppressants.

Figure 2e (IHC) and j (DIF) show heart tissue with positive staining of alpha 1 antitrypsin antibody (brown staining, blue arrows; Fig. 2e), and in Fig. 2j, positive staining to VZV antibody (round, white structures), both utilizing FITC-conjugated IgG antibodies (red arrows). As noted above, observed autoreactivity against skin Pacinian corpuscles (PCs) and some nerves was confirmed by co-localization with antibody to PPG 9.5, and by modified silver (Bielschowsky) staining, performed as previously described.16 Figure 3 shows H&E staining and DIF demonstrating immunoreactivity against a partially autolytic PC utilizing FITC-conjugated antihuman IgM, complement/C3 and fibrinogen. Figure 3b shows the corresponding H&E for the DIF images, displaying focal dermal autolysis, as well as a lymphohistocytic infiltrate surrounding a PC. Finally, in Fig. 3d we demonstrate positive staining of a PC, utilizing modified Bielschowsky silver staining. We demonstrate some of the most prominent H&E and DIF patterns observed, as well as the improvement of the quality and power of DIF staining by the use of simultaneous multicolor fluorescence and counterstaining of cell nuclei. The DIF results were classified as follows: (0, negative; +, weak positive; ++ and +++, positive; and ++++, maximum positivity). We noted: (1) deposits of IgG in a granular pattern at the skin epidermal BMZ; as well as (2) at the BMZ of the sebaceous glands and within cytoplasms of selected sebocytes (+++); (3) deposits of IgM in a granular pattern at the epidermal BMZ (+++); (4) deposits of complement/C3 in a granular pattern at the epidermal BMZ and the sebaceous gland BMZ (+++); and (5) deposits of fibrinogen, in a granular pattern at the epidermal BMZ (++). In addition, we found autoreactivity to multiple cells junctions within cardiac tissue, with FITC-conjugated anti-human IgG, complement/C3 and fibrinogen antibodies. In the kidney, reactivity was also detected with these antibodies, and further with FITC-conjugated anti-human IgA. Immunohistochemistry studies Immunohistochemistry studies were as previously documented.16,17 Testing for HSV-1 and -2 (Dako) was performed, with negative results. We utilized IHC stains for: (1) blood vessel endothelium, including von Willebrand factor, CD34 and CD31; (2) D2-40 for lymphatic endothelium; and (3) smooth muscle actin to confirm vascular co-localization of positive alpha 1 antitrypsin staining. Staining with polyclonal rabbit anti-human matrix metalloproteinase 9 was negative in all samples. Staining for VZV was performed using IE62 (0361) antibodies (sc-58211; Santa Cruz Biotechnology, Santa Cruz, International Journal of Dermatology 2011 CA, USA), with positive staining observed in multiple organs (Figs 1–3). We also stained the VZV-positive cells with CD3, CD4, CD5 and CD8, to co-localize infiltrating lymphocytes to these cells. In addition, we found IHC staining to antigen-presenting cells in the areas of VZV infection, characterized by positive S-100, myeloid/ histioid and HAM-56 positivity in multiple organs. We found strongly positive IHC staining for alpha 1 antitrypsin in most organs (Figs 1–3). In control, routine skin biopsies from living patients affected by El BagreEPF, as well as in unaffected, negative control biopsies from the endemic area, alpha 1 antitrypsin IHC staining was negative (negative controls for the DIF and IHC staining were obtained from cadaver donors at the same hospital, deceased secondary to cardiac arrest or traumatic injuries). The presence of strong staining for mast cell tryptase (MCT) and immunoglobulin D (IgD) was seen around the vessels, sweat and sebaceous glands. Finally, control tissues were consistently negative when tested for HSV-1 and -2, VZV and anti-alpha 1 antitrypsin utilizing IHC and DIF. Discussion Varicella-zoster virus is an ubiquitous, neurotropic alpha herpes virus, causes chickenpox (varicella), becomes latent in dorsal root ganglia at all levels of the neuraxis, and may clinically represent years following initial infection to produce shingles (zoster).18 Years ago when fogo selvagem was more prevalent in Brazil, VZV superinfection was documented with occasional lethal outcomes.19,20 Both primary and recurrent VZV infections may be fatal in immunosuppressed patients. In our patient, we demonstrated the presence of VZV antibody in multiple organ systems. The possibility of concurrent HIV infection was excluded in our patient by both polymerase chain reaction and ELISA testing. For many years, herpes virus has been linked to pemphigus as a possible etiopathogenetic factor, or as a complication of the immunosuppressive treatment.2–5 Our study is the first report in the literature linking the presence of VZV to a strong, disseminated presence of alpha 1 antitrypsin antibodies in a patient affected by El Bagre-EPF receiving large dosages of immunosuppressant agents. Based on the clinical pre mortem findings and autopsy, this patient was affected with disseminated intravascular coagulation, with the additional systemic presence of VZV and alpha 1 antitrypsin antibodies in association with most blood and lymphatic vessels. Selected previous studies document the presence of significant levels of alpha 1 antitrypsin in viral infections.21,22 The authors suggested that serine proteases are responsible for triggering inflammatory cascades, resulting in ª 2011 The International Society of Dermatology Abreu Velez et al. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 increased titers of these proteins. Alpha 1 antitrypsin is a small glycoprotein that readily diffuses throughout interstitial fluids. It functions as an inhibitor of serine proteases in general, but the critical targets are the proteases released by stimulated neutrophils, specifically cathepsin G and, more particularly, neutrophil leukocyte elastase.21,22 Alpha 1 antitrypsin is considered a suicidal protein, reflecting the patient’s ability to respond to stress by increased synthesis, yielding a potential fourfold increase in plasma concentration in an acute phase state. In our case, we speculate that the patient’s body began producing this enzyme rapidly, to protect against deleterious effects of the secondary VZV infection. The presence of this protease inhibitor, and/or the presence of antibodies against this inhibitor may represent contributory factors in the outcome of our patient. Kaposi’s varicelliform eruption represents widespread cutaneous HSV infection in patients with pre-existing dermatoses, including fogo selvage.8,19,20 Also, chicken pox and other infections may occur in patients with EPF. Occasionally, these infections may present as nosocomial infections in hospital wards, especially if adequate bed spacing and barrier nursing methods are not employed; these infections may in turn result in a significant mortality increase in these patients.19,20 During initial exposure, HSV uses mucosal and epithelial cells, including epidermal keratinocytes, as its primary portal of entry and spreads through the epithelium.16,23 It has also been shown that the replication of HSV virus in cultured cells is accompanied by the appearance of cell receptors that have an affinity for the Fc region of IgG.16 The findings may help to explain observed associations of HSV and/or VZV with areas of the skin containing immunoglobulins deposited by EPF. In regard to the structural damage in the kidney, heart, the nerves23 and possibly other organs, we believe the damage is associated with the presence of autoantibodies to these organs, as many of them are rich in plakins, and patients with El Bagre-EPF have significant antibodies to plakin molecules.23 The reasons for reactivity to MCT and IgD in several biopsies, including sites other than the skin, also remain unknown. However, some authors have also reported strong responses to IgD with alpha 1 antitrypsin, and with infections due to other microorganisms.24 In the referral hospital caring for our patient, the median hospitalization of patients affected by El Bagre-EPF ranges from 6 to 12 months, which can make these patients vulnerable to nosocomial diseases. We conclude that vigilance to prevent infections with bacterial, fungal, virus and parasitic secondary infections is crucial, especially in long hospitalizations of these patients. Physicians need to recognize the risk of exposing these patients to any viral, bacterial, mycoplasmic, parasitic and/or other ª 2011 The International Society of Dermatology Endemic pemphigus and chicken pox Report 1 7 superinfecting agent in the event of a positive test for any infections agent, especially those of the herpes family (i.e. Tzanck smear or HSV serology). Finally, we propose a specific, synergistic mechanism to account for the increased alpha 1 antitrypsin found in our patient; additionally, pertinent cases need to be documented. However, we do strongly encourage physicians to perform autopsies on patients with fatal complications of autoimmune bullous disease therapy, and thus preserve organ tissues for further studies.
