A high frequency of anti-Ro (SSA) circulating antibodies and lack of HLA-DR4 association described recently in Greek rheumatoid arthritis (RA) patients, prompted us to study their clinical and laboratory picture and compare it with that described in the literature. One hundred and ninety seven patients with definite or classical RA were divided into three groups A, B, and C with age at disease onset below 39, between 40 and 59, and above 60 years respectively. Disease duration below 5 and above 5 years resulted in further division of each group into subgroups 1 and 2. With few exceptions, there were no significant differences between the groups in terms of maximal articular index, lymphadenopathy, splenomegaly, hepatomegaly, frequency of rheumatoid nodules and lowest hematocrit, highest erythrocyte sedimentation rate, and C-reactive protein values. The presence of rheumatoid factor, antinuclear antibodies, cryoglobulins, and elevated levels of globulins, C3 and C4 in patients' sera were not significantly different among the groups. A statistically significant radiologic deterioration was observed with disease duration, common in all groups. Diffuse interstitial lung disease was the most common pulmonary abnormality noted. There were no differences between the groups. Penicillamine toxicity was independent of age and disease duration. This study suggests that the clinical picture of RA in Greece is similar to that in other populations and that there are no significant differences in general among its age groups.

A young dog was presented for cyanosis and right heart failure. Radiographic and CT characteristics included right heart/pulmonary artery enlargement, hepatomegaly, abdominal effusion, and severe, generalized air-space filling. Focal increased opacities were present in the peripheral lung, as were multiple pulmonary blebs and bullae. Echocardiographic findings were consistent with cor pulmonale and pulmonary hypertension. Bronchoscopic findings were consistent with chronic inflammation. Pulmonary alveolar proteinosis (PAP) was confirmed at necropsy. Pulmonary alveolar proteinosis is an interstitial lung disease that results in accumulation of phospholipoproteinaceous material and should be included as a differential diagnosis for dogs with these clinical and imaging characteristics.

Interstitial lung and liver disease (ILLD) is caused by biallelic mutations in the methionyl-tRNA synthetase (MARS) gene. To date, no genetic changes other than missense variants were reported in the literature. Here, we report a five-month old female infant with typical ILLD (failure to thrive, developmental delay, jaundice, diffuse interstitial lung disease, hepatomegaly with severe steatosis, anemia, and thrombocytosis) showing novel phenotypes such as kidney stones, acetabular dysplasia, prolonged fever, and extreme leukocytosis. Whole exome sequencing revealed a novel truncating variant (c.2158C>T/p.Gln720Stop) together with a novel tri-nucleotide insertion (c.893_894insTCG that caused the insertion of an arginine at amino acid position 299) in the MARS gene.

Aggressive natural killer (NK) cell leukemia (ANKL) is a rare form of leukemia with an aggressive clinical course. It commonly involves the peripheral blood, bone marrow, liver, and spleen but rarely involves the lungs. We report a 36 year-old woman who presented with pulmonary lesions we suspected to be interstitial lung disease on an imaging study. A lung biopsy showed extensive lymphoid infiltrate growing along pre-existing alveolar septa without destroying the alveolar spaces. Further workup revealed hepatomegaly, borderline splenomegaly, and multiple lymphadenopathies. Her laboratory tests showed leukocytosis, anemia, thrombocytopenia, abnormal liver enzymes, and elevated lactate dehydrogenase. A bone marrow (BM) aspirate smear revealed many intermediate to large lymphocytes with dispersed chromatin, basophilic cytoplasm, and some azurophilic granules. A BM biopsy showed hypercellularity with interstitial lymphoid infiltrate in a background of trilineage hematopoiesis and histiocytosis with hemophagocytosis. Immunohistochemical studies performed on both the lung and BM biopsies showed the neoplastic cells to be positive for CD2, CD3, CD7, CD56, granzyme B, phosphor-MAPK (pMAPK), EBER (Epstein-Barr Virus-encoded small RNA) by in situ hybridization; they were negative for CD4, CD5, CD8, CD30, LMP1, and phospho-STAT3 (pSTAT3). A flow cytometry analysis of the BM aspirate identified a population of atypical lymphocytes with the NK cell phenotype. Molecular studies were negative for T-cell receptor gene rearrangements, and the neoplastic cells displayed a complex karyotype. The patient responded initially to chemotherapy but died of multiorgan failure two months after the diagnosis. We present a case of ANKL mimicking interstitial lung disease with the activation of MAPK pathway.
