The Hermansky-Pudlak syndrome is a form of oculocutaneous albinism, characterized by a qualitative platelet defect and deposition of ceroid-like material throughout the reticuloendothelial system. During a 16 month period five patients with Hermansky-Pudlak syndrome presented with symptoms, chest films and pulmonary function studies consistent with restrictive pulmonary disease. In two patients, lung biopsies revealed diffuse interstitial fibrosis. However, light and electron microscopy demonstrated ceroid-like material within alveolar macrophages. In addition, two patients presented with inflammatory bowel disease with deposition of ceroid-like material in the colon. This disorder appears to be more common than is currently recognized and should be considered in the differential diagnosis of diffuse interstitial pulmonary disease and inflammatory bowel disease. A relationship between the deposition of ceroid-like material and pulmonary fibrosis is discussed in light of recent research concerning inflammatory processes. In view of the serious pulmonary, gastrointestinal and hematologic consequences of this syndrome, there is a need for genetic counseling of these patients.

This is a report on two brothers with the Hermansky-Pudlak syndrome who developed pulmonary fibrosis. In the first, a gradual course lasting 13 years was observed, the patient finally died of long-standing colitis. His brother died of progressive respiratory failure 15 months after the subjective onset of the disease. Immunosuppressive therapy proved ineffective.

The Hermansky-Pudlak syndrome (HPS) is a triad of tyrosine-positive albinism, platelet dysfunction, and the deposition of an abnormal ceroid-like pigment in the tissues. Complications of the syndrome, such as pulmonary fibrosis, renal failure, and cardiomyopathy, have been described. Granulomatous colitis has been documented in several families with the HPS. The bowel disease of the HPS is a unique type of inflammatory bowel disease with clinical features suggestive of idiopathic ulcerative colitis and pathologic features suggestive of Crohn's disease. Analogous to the presentation of Crohn's disease with perianal and perirectal involvement, we describe the occurrence of perianal disease and a perirectal abscess in a 29-yr-old woman with HPS and mild granulomatous colitis.

Two cases of Hermansky-Pudlak syndrome with interstitial pneumonia were reported. Both patients had evidence of pulmonary involvement characterized by diffuse bilateral infiltrates. They had oculocutaneous albinism. Case 1 was a 55 year-old female who had a history of easy bruising. Her two sisters were albino and had died of pulmonary fibrosis. One of them was diagnosed as Hermansky-Pudlak syndrome on autopsy. Bone marrow aspirate disclosed typical macrophages with ceroid-like pigment. Transbronchial lung biopsy showed alveolar wall thickening. Lumi-aggregometer showed a decrease of platelet aggregation and an absence of ATP release. Case 2 was a 43 year-old female and had a bleeding tendency during a surgical procedure. Lumi-aggregometer showed normal platelet aggregation but an absence of ATP release. BALF analysis did not disclose macrophages with ceroid-like pigment.

In addition to the triad in the Hermansky-Pudlak syndrome (tyrosine-positive oculocutaneous albinism, mild bleeding tendency with a normal platelet-count and widespread accumulation of ceroid-like pigment in various organs), we document severe pulmonary fibrosis, pseudomelanosis coli and deeply pigmented renal cortex. In the liver, innumerable number of pigment-laden Kupffer cells and macrophages in the Glisson capsule were seen. Interestingly, many intralysosomal accumulations of the pigment within the hepatocytes were found by electron microscopy, suggesting that these configurations possibly resulted from a dysfunction of the lysosome itself, especially with regard to loss of digestive and secretory activity. The triad and other complications may also be resultants of a lysosomal dysfunction.

Clinical and pathologic evidence for interstitial pulmonary fibrosis occurring in some patients with the Hermansky-Pudlak syndrome is well described in the literature, but data on immunologic mechanisms operating in this form of lung disease have not been published. In this case report, we describe bronchoalveolar lavage (BAL) findings in a patient with this syndrome. Recovered alveolar macrophages (AM) contained the characteristic ceroidlike material previously described in interstitial macrophages in pathologic specimens. The BAL analysis was similar to that seen in idiopathic pulmonary fibrosis, with increased levels of immunoglobulins and numbers of IgG and IgA secreting cells, and normal percentages of putative helper and suppressor T-cell subsets. In addition, superoxide production by stimulated AM was increased, possibly secondary to phagocytosis of the ceroidlike material. The lavage in this patient was compatible with a mild inflammatory process that was consistent with gallium scan results and the patient's clinical course.

The Hermansky-Pudlak syndrome consists of tyrosine-positive albinism, a defect in the second phase of platelet aggregation, and widespread accumulation of a ceroidlike pigment in tissue. Pulmonary fibrosis has also been reported. In this paper, we describe two families with documented Hermansky-Pudlak syndrome in which four members, two from each family, developed granulomatous colitis. This adds another disease entity to those associated with this syndrome. We discuss possible connecting links between these disease expressions.

The Hermansky-Pudlak syndrome consists of albinism, platelet function defect, pigment laden macrophases and, on occasions, pulmonary fibrosis. The clinical course and postmortem findings of a patient with pulmonary fibrosis which mimicked cryptogenic fibrosing alveolitis are reported. Histological examination revealed a chronic inflammatory infiltrate of pigment laden microphages.

Peptides that modulate mesenchymal cell function have been detected in the fibrotic lung disorders once physiologic dysfunction is present. Despite this close association with manifest disease, their role in initiating alveolar remodeling remains unknown. We examined the hypothesis that one potent peptide, platelet-derived growth factor (PDGF), would be present at the alveolar surface before the onset of physiologic dysfunction in patients in whom pulmonary fibrosis subsequently develops. Bronchoalveolar lavage and physiologic assessment were performed in asymptomatic patients with the Hermansky-Pudlak syndrome (n = 30), obligate heterozygous (n = 9), and normal volunteers (control group). Lavage cell number and profile were normal, but alveolar macrophages demonstrated characteristic autofluorescence and ultrastructural features of ceroid. Lavage fluid from physiologically normal patients with Hermansky-Pudlak syndrome and from those with occult restrictive disease demonstrated two PDGF-related peptides (14 kd and 38 kd). Radioligand binding and fibroblast proliferation assay demonstrated that the peptides were functional. By immunoassay the concentration of PDGF in lavage fluid was six times greater than control values (p < 0.01). In situ hybridization together with bioassay indicated that alveolar macrophages were one cellular source of PDGF. Similar results were obtained for heterozygotes. These data identify macrophage-derived PDGF peptides as important candidate molecules in the initiation of alveolar remodeling in the fibrotic lung disorders.

The Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disease characterized by a triad of oculocutaneous albinism, accumulation of auto-fluorescent ceroid-like pigments within macrophages, and bleeding tendency due to a storage pool disease of the platelets. We report an autopsy case (39y, male), who died of pulmonary fibrosis and hemorrhage, with analysis of auto-fluorescent ceroid-like pigments (CLP). Pigmented macrophages were seen in almost all organs, especially marked in bone marrow, spleen, liver, colon, lymph nodes and kidneys. Ultrastructurally, CLP was intracytoplasmic electron-dense and -lucent congeries. Histochemical characteristics and auto-fluorescence of CLP showed similarities to ceroid. Substance which revealed brilliant lemon yellow autofluorescent was extracted from homogenized tissue of spleen with chloroform/methanol (2:1), then separated by thin-layer chromatography. The fluorescent substance had an excitation maximum at 360nm and a fluorescence maximum at 440nm, which is the same characteristic as described fluorescent lipid peroxidation products in vitro.
